               MERGER PROPOSED
         YOUR VOTE IS VERY IMPORTANT


Dear Shareholders:

    The Imatron board of directors is soliciting your proxy and seeking your
approval of Imatron's merger with a wholly owned subsidiary of General Electric
Company which will result in:

    - Imatron becoming a wholly owned subsidiary of GE; and

    - each outstanding share of Imatron common stock being converted into the
      right to receive $1.89 payable in shares of GE common stock based on the
      average of the daily volume-weighted trading prices of GE common stock on
      the NYSE for the ten consecutive trading day period ending five calendar
      days prior to the closing of the merger.


    On October 29, 2001, there were 105,331,524 shares of Imatron common stock
outstanding, 10,022,801 shares of Imatron common stock issuable upon the
exercise of outstanding stock options, and 6,465,555 shares of Imatron common
stock issuable upon exercise of outstanding warrants.


    IMATRON'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT.
AFTER CONSIDERATION OF NUMEROUS FACTORS, INCLUDING RECEIPT OF A FAIRNESS OPINION
FROM THOMAS WEISEL PARTNERS, IMATRON'S BOARD HAS DETERMINED THAT THE MERGER
AGREEMENT IS ADVISABLE AND FAIR TO AND IN THE BEST INTERESTS OF IMATRON AND ITS
SHAREHOLDERS AND RECOMMENDS THAT IMATRON'S SHAREHOLDERS VOTE FOR THE ADOPTION OF
THE PLAN OF MERGER.

    The shares of Imatron common stock trade on the Nasdaq National Market under
the symbol "IMAT." The shares of GE common stock are principally listed on the
New York Stock Exchange under the symbol "GE."


                               /s/ S. Lewis Meyer


                                 S. Lewis Meyer
                            Chief Executive Officer

    NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED THE SHARES OF GE COMMON STOCK TO BE
ISSUED UNDER THIS PROXY STATEMENT/PROSPECTUS OR DETERMINED IF THIS PROXY
STATEMENT/PROSPECTUS IS ACCURATE OR ADEQUATE. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.


    This proxy statement/prospectus is dated November 14, 2001 and is first
being mailed to shareholders of Imatron on or about November 16, 2001.


                                  IMATRON INC.

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                        TO BE HELD ON DECEMBER 19, 2001



                                                               November 14, 2001


To our shareholders:


    A special meeting of shareholders of Imatron Inc., a New Jersey corporation,
will be held at the Embassy Suites Hotel, 250 Gateway Boulevard, South San
Francisco, California, on December 19, 2001 at 10:30 a.m., local time, for the
purpose of voting on the following proposals:


        1.  To consider and vote upon a proposal to adopt the Agreement and Plan
    of Merger, dated as of September 21, 2001, by and among Imatron, General
    Electric Company, a New York corporation, and Ruby Merger Corp., a wholly
    owned New Jersey subsidiary of GE, that provides for, among other things, a
    merger that will result in Imatron becoming a wholly owned subsidiary of GE
    and Imatron shareholders becoming GE stockholders. In the merger, each share
    of Imatron common stock will be converted into the right to receive $1.89
    payable in shares of GE common stock based on the average of the daily
    volume-weighted trading prices of GE common stock on the NYSE for the ten
    consecutive trading day period ending five calendar days prior to the
    closing of the merger, plus cash in lieu of fractional shares.

        2.  To consider and vote upon any other matters properly presented for
    action at the special meeting, including the postponement and adjournment of
    the special meeting in order to solicit additional votes to approve the
    merger agreement if the secretary of the special meeting determines that
    there are not sufficient votes to approve the merger agreement.

    The close of business on October 29, 2001, has been fixed as the record date
for determining those shareholders entitled to vote at the special meeting and
any adjournments or postponements of the special meeting. Therefore, only
shareholders of record on October 29, 2001, are entitled to notice of, and to
vote at, the special meeting and any adjournments or postponements of the
special meeting.

                       By Order of the Board of Directors


                               /s/ S. Lewis Meyer


                                 S. Lewis Meyer

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  WHAT IS THE PROPOSED TRANSACTION FOR WHICH I AM BEING ASKED TO VOTE?

    A.  Imatron proposes to be acquired by GE pursuant to the terms of a merger
agreement. In the merger, Ruby Merger Corp., a wholly owned subsidiary of GE,
will merge into Imatron with Imatron surviving the merger. As a result, Imatron
will become a wholly owned subsidiary of GE.

Q.  WHAT EFFECT WILL THE MERGER HAVE ON MY IMATRON SHARES?

    A.  Each share of your Imatron common stock will be exchanged for a fraction
of a share of GE common stock having a market value of approximately $1.89, plus
cash instead of fractional shares. The actual number of GE shares that you
receive will be determined based on the average of the daily volume-weighted
trading prices of GE common stock on the NYSE for the 10 consecutive trading-day
period ending five calendar days prior to the closing of the merger.


    For example, if the average per share price of GE stock for the valuation
period were $38.77 (which was the closing price of GE common stock on the NYSE
on November 5, 2001) an Imatron shareholder holding 750 shares of Imatron common
stock would receive 36 shares of GE common stock, $29.08 in cash instead of
fractional shares.


Q.  HOW WILL SHAREHOLDERS KNOW WHAT THE ACTUAL EXCHANGE RATIO IS?

    A.  We will issue a press release prior to the special meeting that will
disclose the exchange ratio assuming that the closing of the merger occurs on
the same day as the shareholders meeting. If the closing of the merger is
delayed for any reason, then the exchange ratio could change. The exchange ratio
is the fraction of a share of GE common stock that you would receive in the
merger for each share of Imatron common stock you own. Additionally, you can
call (800) 250-7979 to receive hypothetical information about the exchange ratio
updated as of the week of your call.

Q.  WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER ON IMATRON
  SHAREHOLDERS?

    A.  The consummation of the merger is conditioned upon the receipt by GE and
Imatron of legal opinions from their respective tax counsel to the effect that
the merger will qualify as a tax-free reorganization under the Internal Revenue
Code. Assuming that the merger so qualifies, you will not recognize any gain or
loss for U.S. federal income tax purposes on the exchange of your Imatron shares
for GE shares in the merger except for any gain or loss attributable to cash
received instead of fractional GE shares. The tax consequences to you of the
transaction will depend on your particular facts and circumstances. You should
consult your tax advisor for a full understanding of the tax consequences of the
merger to you.

Q.  AM I ENTITLED TO APPRAISAL RIGHTS?

    A.  No. Under New Jersey law, which governs Imatron and the rights of
Imatron shareholders in the merger, you are not entitled to appraisal rights.

Q.  WHEN AND WHERE IS THE SPECIAL MEETING?


    A.  The Imatron special meeting is scheduled to take place on December 19,
2001 at 10:30 a.m., local time, at Embassy Suites Hotel, 250 Gateway Boulevard,
South San Francisco, California.


Q.  WHAT WILL I VOTE ON AT THE SPECIAL MEETING?

    A.  At the special meeting you will be asked to vote to approve the merger
agreement and the merger.

                                       1

Q.  WHAT VOTE IS REQUIRED FOR APPROVAL?

    A.  The merger agreement and the merger must be approved by a majority of
the votes cast at the special meeting, so long as a quorum is present.

Q.  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

    A.  We expect to complete the merger promptly after we receive the Imatron
shareholder approval at the special meeting and after we receive all necessary
regulatory approvals.

Q.  WHAT DO I NEED TO DO NOW?

    A.  After carefully reading and considering the information contained in
this document, please fill out and sign the proxy card, and then mail your
signed proxy card in the enclosed envelope as soon as possible so that your
shares may be voted at the special meeting. Your proxy card will instruct the
persons named on the card to vote your shares at the special meeting as you
direct on the card. If you sign and send in your proxy card and do not indicate
how you want to vote, your proxy will be voted FOR the adoption of the merger
agreement. If you abstain, the effect will be a vote against the merger. YOUR
VOTE IS VERY IMPORTANT.

Q.  MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

    A.  You may change your vote at any time before your proxy is voted at the
meeting. You can do this in one of three ways. First, you can send a written
notice stating that you want to revoke your proxy. Second, you can complete and
submit a new proxy card. If you choose either of these two methods, you must
submit your notice of revocation or your new proxy card to:

       Imatron Inc.
       389 Oyster Point Boulevard
       South San Francisco, California 94080
       Attention: Corporate Secretary

    Third, you can attend the Imatron special meeting and vote in person. Simply
attending the meeting, however, will not revoke your proxy; you must vote at the
meeting. If you have instructed a broker to vote your shares, you must follow
directions received from your broker to change your vote.

Q.  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

    A.  No. After the merger is completed, you will receive written instructions
for exchanging your stock certificates.

Q.  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
  SHARES FOR ME?

    A.  Your broker will only vote your shares if you provide instructions on
how to vote. You should follow the directions provided by your broker to vote
your shares. You cannot vote shares held in "street name" by returning a proxy
card directly to us.

Q.  WHAT DOES IMATRON'S BOARD OF DIRECTORS RECOMMEND?

    A.  After consideration of numerous factors, including the receipt of a
fairness opinion from Thomas Weisel Partners, Imatron's board of directors has
determined that the proposed merger is advisable and fair to and in the best
interests of Imatron and its shareholders and unanimously recommends that you
vote FOR the proposal to approve the merger agreement and the merger.

RUBY MERGER CORP.
3135 Easton Turnpike
Fairfield, Connecticut 06431-0001
(203) 373-2211

    Ruby Merger Corp., a New Jersey corporation, is a company formed by GE on
September 7, 2001 solely for use in the merger.


WHAT YOU WILL RECEIVE IN THE MERGER
(PAGE 40)


    If the merger is completed, for each share of Imatron common stock you own
immediately prior to the merger, you will be entitled to approximately $1.89
worth of GE common stock.

                                       4

You will receive cash instead of fractional shares of GE common stock. The
number of shares of GE common stock to which you will be entitled for each
Imatron share will be determined by dividing $1.89 by the average of the daily
volume-weighted sales prices per share of GE common stock on the NYSE for the
ten consecutive trading days ending on the trading day which is five calendar
days prior to the date on which the merger occurs and then rounding to the
nearest thousandth. The price of GE common stock at the time of completion of
the merger may be higher or lower than the average GE price on which the merger
exchange ratio is based. As a result, the value of the shares of GE common stock
to which you become entitled on the date the merger closes may be more or less
than $1.89 per share of Imatron common stock.


    EXAMPLE:  If you own 750 shares of Imatron common stock when the merger is
consummated and if the average GE price on which the exchange ratio is based is
$38.77 (using the closing price of GE common stock on the NYSE on November 5,
2001 for purposes of this example), then after the merger you would be entitled
to receive 36 shares of GE common stock, $29.08 cash instead of fractional
shares.


    You may call, toll-free, (800) 250-7979 for information concerning the
estimated number of shares of GE common stock that would be issued in exchange
for your Imatron common stock if the merger were consummated as of the week you
call.


THE SPECIAL MEETING
(PAGE 15)



    At the special meeting, the holders of Imatron common stock will be asked to
approve and adopt the plan of merger. The close of business on October 29, 2001
is the record date for determining if you are entitled to vote at the special
meeting. On that date, there were approximately 105,331,524 shares of Imatron
common stock outstanding. Each share of Imatron common stock is entitled to one
vote at the special meeting. A majority of the outstanding shares for which
votes are cast at the special meeting is required to approve and adopt the plan
of merger. On the record date, directors and executive officers of Imatron owned
and had the right to vote 2,242,619 shares of Imatron common stock
(approximately 2.1% of the shares of Imatron common stock then outstanding).
S. Lewis Meyer, Douglas P. Boyd, Terry Ross and Jose Maria Salema Garcao have
executed shareholder agreements relating to the voting of their shares (see
below).



SHAREHOLDER AGREEMENTS
(PAGE 54)


    To induce GE to enter into the merger agreement, S. Lewis Meyer, Douglas P.
Boyd, Terry Ross and Jose Maria Salema Garcao entered into shareholder
agreements with GE. They have agreed, without any additional consideration being
paid to them, to vote 7,189,556 of shares owned directly by them and any
additional shares that may become owned by them (including 3,627,008 shares
issuable upon exercise of stock options or warrants) in favor of the merger.


IMATRON'S REASONS FOR THE MERGER
(PAGE 24)


    The Imatron board has approved the merger agreement and recommends that you
vote to approve and adopt the merger agreement and to approve the merger. The
Imatron board believes that the merger is in the best interests of Imatron and
its shareholders. In reaching its decision, the Imatron board considered a
number of factors, including the following (to which no relative weights were
assigned):

    - Imatron's need for significant additional capital to operate and compete,
      and the difficulty in obtaining such capital;

    - the lack of viable strategic alternatives;

    - the relative strength of GE and the specific financial and other terms of
      the merger agreement;

    - the receipt of an opinion from Thomas Weisel Partners that the merger
      consideration was fair to the Imatron shareholders from a financial point
      of view;

                                       5

    - and the potential strategic and other benefits of the merger to Imatron
      shareholders, employees and customers.


    To review Imatron's reasons for the merger in greater detail, see "The
Merger--Recommendation of the Imatron Board of Directors; Reasons for the
Merger" on page 24.



INTERESTS OF CERTAIN PERSONS IN THE MERGER
(PAGE 33)


    In considering the recommendation of the Imatron board regarding the merger,
you should be aware of the interests which executive officers and directors of
Imatron have in the merger that are different from your interests as
shareholders.


    On September 21, 2001 an aggregate of approximately 2,861,508 shares of
Imatron common stock were subject to options granted to executive officers and
directors of Imatron under Imatron's stock option plans which will terminate at
the effective time of the merger. Approximately 1,926,508 of these that have an
exercise price below $1.89 per share will be converted into the right to receive
shares of GE stock equal in value to the "spread" between the $1.89 and the
applicable strike price. The remaining options, to the extent held by employees
that continue with GE after the merger, will be cancelled in exchange for the
right to receive new GE options.


    On September 21, 2001, Imatron and S. Lewis Meyer executed a separation
agreement. Under this agreement, Mr. Meyer's employment with Imatron will
terminate at the effective time of the merger. Mr. Meyer will be entitled to
receive payments and debt forgiveness valued at approximately $626,950, but will
not be entitled to receive any GE stock options in exchange for options he holds
to purchase Imatron shares (which options will be cancelled at the effective
time of the merger).


    The Imatron board recognized all the interests described above and concluded
that these interests did not detract from the fairness of the merger to the
holders of Imatron common stock who are not executive officers or directors of
Imatron. Please refer to page 34 for more information concerning retention
agreements and other arrangements for Imatron's executive officers and
directors.



REGULATORY APPROVALS
(PAGE 56)



    In order to complete the merger, we must obtain the approval of federal and
foreign regulatory authorities. We have filed, or soon will file, all of the
required applications or notices with these regulatory authorities. The initial
filings under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 were made
effective October 19, 2001. Although we expect to obtain the necessary
approvals, we cannot be certain we will obtain them.



CONDITIONS TO THE MERGER
(PAGE 46)


    GE and Imatron will not complete the merger unless a number of conditions
are satisfied or waived by them, the most significant of which are: the holders
of a majority of the shares of Imatron common stock for which votes are cast at
the special meeting must approve and adopt the plan of merger; the GE common
stock issuable in the merger shall be authorized for listing on the NYSE; the GE
registration statement with respect to the GE common stock to be issued to
Imatron shareholders must be declared effective by the SEC and all necessary
authorizations imposed by state securities laws must have been received; the
parties must have received legal opinions from their respective tax counsel to
the effect that the merger will qualify as a tax-free reorganization under the
Internal Revenue Code, and that each of GE, Imatron and Ruby Merger Corp. will
be parties to that reorganization within the meaning of the Internal Revenue
Code; there must be no law, injunction or order that prohibits the merger; the
representations and warranties of each of GE and Imatron contained in the merger
agreement must be true and correct in all material respects as of the time given
and as of the closing; GE shall have received satisfactory results of
environmental site assessments of the real property at which Imatron and its
subsidiaries operate; and there must have been no material adverse change with
respect to Imatron.

                                       6

    Following the execution of the merger agreement, two civil actions were
filed against Imatron and its directors, seeking injunctive relief and damages
for, among other things, breach of the directors' fiduciary duties to Imatron
shareholders. See "THE MERGER--Shareholder Litigation." If these actions are
successful, or are pending at the proposed effective time for the merger and it
is determined that the existence of these actions is material, GE would have the
right to refuse to consummate the merger.

    The party entitled to the benefit of some of these conditions may waive
these conditions.


TERMINATION OF THE MERGER AGREEMENT
(PAGE 47)


    Imatron and GE can agree at any time to terminate the merger agreement
without completing the merger, and the merger agreement may be terminated by
either party if any of the following events occur: the other party materially
breaches any of its representations, warranties or obligations under the merger
agreement and does not cure the breach within five business days after receiving
notice of the breach; the merger is not completed by June 15, 2002; a court or
other governmental authority permanently prohibits the merger; the holders of
Imatron common stock do not approve the merger agreement; or Imatron enters into
an agreement to effect a more favorable business combination (subject to various
conditions).

    In addition, GE may terminate the merger agreement if the Imatron board
changes its recommendation in favor of the merger, recommends in favor of a
business combination other than the merger with GE or fails to recommend against
the acceptance of any tender offer or exchange offer for Imatron common stock.


TERMINATION FEES
(PAGE 48)



    To compensate GE if the merger is not consummated, the merger agreement
provides for termination fees plus reimbursement of actual expenses, up to a
maximum expense reimbursement of $1.5 million, under a variety of circumstances.
The termination fee, when added to any amounts received by GE pursuant to the
stock option agreement between GE and Imatron in connection with Imatron's
completion of a transaction with a party other than GE, shall not exceed a total
of $11 million.



NO SOLICITATION OF COMPETING TRANSACTIONS
(PAGE 43)


    The merger agreement imposes conditions on Imatron's ability to solicit,
encourage or participate in discussions with respect to any alternative
acquisition transactions with third parties, though Imatron's board can provide
information or negotiate with third parties to the extent required by their
fiduciary duties. Imatron must promptly notify GE if it receives offers or
proposals for any such alternative transactions.


STOCK OPTION AGREEMENT
(PAGE 51)


    Also as a condition to GE's entering into the merger agreement, GE and
Imatron entered into a stock option agreement, whereby Imatron has granted to GE
an option to purchase shares that, immediately prior to their issuance, would
represent up to 19.9% of Imatron's outstanding shares of common stock at an
exercise price of $1.89 per share, payable in cash. The option becomes
exercisable by GE only if specified events occur. The stock option agreement and
the termination fees may discourage persons from making a competing offer for
Imatron common stock.


APPRAISAL RIGHTS
(PAGE 38)


    Under New Jersey law, Imatron shareholders have no right to an appraisal of
the value of their shares of Imatron common stock in connection with the merger.
This is because the GE shares are listed on the New York Stock Exchange.

                                       7

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES


(PAGE 37)


    The consummation of the Merger is conditioned upon the receipt by Imatron
and GE of legal opinions from their respective tax counsel, to the effect that
the merger will constitute a reorganization for federal income tax purposes.
Accordingly, among other things, no gain or loss will be recognized by the
shareholders of Imatron on the exchange of their shares of Imatron common stock
for shares of GE common stock pursuant to the merger, except to the extent of
any gain or loss attributable to cash received instead of fractional shares of
GE stock.


    The tax consequences of the merger to you will depend on your particular
facts and circumstances. We urge you to consult your tax advisor to understand
fully the tax consequences of the merger to you. See "The Merger--Material
United States Federal Income Tax Consequences" on page 37.


COMPARISON OF RIGHTS OF IMATRON SHAREHOLDERS AND GE STOCKHOLDERS


(PAGE 57)



    After the merger, Imatron shareholders will become GE stockholders and their
rights as stockholders will be governed by the certificate of incorporation and
bylaws of GE and the New York corporate law. There are a number of differences
between the certificate of incorporation and bylaws of GE and the New York
corporate law and the certificate of incorporation and bylaws of Imatron and the
New Jersey corporate law. These differences are discussed under "Comparison of
Rights of Imatron Shareholders and GE Stockholders."


FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE


(PAGE 36)



    GE and Imatron have made forward-looking statements in this document and in
documents to which we have referred you. These statements are subject to risks
and uncertainties, and we cannot assure you that these statements will prove to
be correct. Forward-looking statements include assumptions as to how GE and
Imatron may perform in the future. You will find many of these statements in the
following sections: "The Merger--Recommendation of the Imatron Board of
Directors; Reasons for the Merger" on page 24; and "The Merger--Opinion of
Thomas Weisel Partners LLC" on page 26.


    Also, when we use words like "believes," "expects," "anticipates" or similar
expressions, we are making forward-looking statements. For those statements, GE
and Imatron claim the protection of the safe harbor for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995.
You should understand that the following important factors, in addition to those
discussed elsewhere in this document and in the documents that we incorporate by
reference, could affect the future results of GE and Imatron and could cause
those results to differ materially from those expressed in our forward-looking
statements. These factors include: the ability to timely and fully realize the
expected cost savings and revenues; the loss of consumer confidence by Imatron's
existing customers; the resulting economic impact of the events of
September 11, 2001 and any potential future military or other conflict; material
adverse changes in economic conditions and in the markets served by GE and
Imatron; regulatory, legal, economic and other changes in the healthcare
industry generally; a significant delay in the expected completion of the
merger; competitive pressures; GE's and Imatron's ability to attract and retain
key personnel; changes in the financial condition of major Imatron customers;
variability of quarterly results; uncertainty of entrance into new markets; and
integration of the acquired business.

SIGNIFICANT FACTORS AFFECTING OPERATING RESULTS


    Sometimes financial results reported in accordance with GAAP include unusual
or infrequent events and factors which are not expected to occur regularly in
the future. Examples of these events and factors include gains or losses on the
sale of businesses, the costs of completing major acquisitions and of other
business development activities, and the costs of business restructurings.
Certain unusual or infrequent events and transactions, as well as other
significant factors and trends, which may be helpful in understanding the past
performance and future prospects of Imatron and GE, are described briefly below.
The following discussion should be read with the "Summary Selected Financial
Data" of Imatron and "Selected Consolidated Financial Data" of GE included on
the previous pages and with the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" of Imatron contained in the
annual reports and other information that Imatron has filed with the SEC, and
with the "Management's Discussion and Analysis of Financial Condition and
Results of Operations" of GE contained in the annual reports and other
information that GE has filed with the SEC. See "Where You Can Find More
Information" on page 66.


    In considering the Selected Consolidated Financial Data of GE, you should be
aware that:

    - the consolidated financial statements represent the combined results of
      all companies that GE directly or indirectly controls;

    - results of associated companies--generally companies that are 20% to 50%
      owned by GE and over which GE, directly or indirectly, has significant
      influence--are included in the financial statements on a "one-line" basis;
      and

                                       11

    - the consolidated financial statements have been restated to reflect a
      two-for-one stock split, which took effect on April 28, 1997, and a
      three-for-one stock split, which took effect on April 27, 2000.

COMPARATIVE PER SHARE DATA


    The following tables present historical per share data of Imatron and GE.
The data presented below should be read in conjunction with the historical
financial statements of GE and Imatron incorporated by reference in this
document. Only the earnings per share data are calculated using the diluted
weighted average of shares outstanding. Because the number of shares of GE
common stock to be issued in the merger will not be known until five calendar
days prior to the completion of the merger, Imatron equivalent per share data
cannot be computed at this time. That information will be available via
telephone, toll-free, at (800) 250-7979. Hypothetical Imatron equivalent per
share data is presented below using the closing sale price of a share of GE
common stock on the NYSE on November 5, 2001 which was $38.77 and a resulting
hypothetical exchange ratio of 0.049. The hypothetical Imatron equivalent per
share data was calculated by multiplying the actual GE per share data by the
hypothetical exchange ratio of 0.049.

                                       13

    GE common stock is principally traded in the United States on the NYSE under
the symbol "GE." Imatron common stock is currently traded on the Nasdaq National
Market under the symbol "IMAT."

    GE declared dividends of $5.647 billion in 2000, or approximately 44% of
GE's 2000 consolidated earnings. Per share dividends declared of $0.57 in fiscal
year 2000 increased 17% from 1999, its 25th consecutive annual increase.
Following the merger, payment of cash dividends by GE in respect of GE common
stock will depend on GE's financial condition, results of operations and any
other factor GE's board of directors may consider relevant.

    At year-end 2000, GE had purchased and placed into treasury a total of
950 million shares having an aggregate cost of $17 billion under a share
repurchase program begun in December 1994. In December 1999, GE's board of
directors increased the authorization to repurchase GE common stock to
$22 billion and authorized the program to continue through 2002. Such shares are
from time to time reissued upon the exercise of employee stock options,
conversion of convertible securities and for other corporate purposes. GE
intends to continue repurchases of shares in the ordinary course under its
ongoing repurchase program between the date of this document and the merger, and
during the valuation period for the merger.


    Set forth below are the last reported sale prices of GE common stock and
Imatron common stock on September 21, 2001, the last trading day prior to the
public announcement of the execution of the merger agreement, and on
November 13, 2001, the last trading day prior to the date of this proxy
statement/prospectus. The GE common stock price is as reported on the NYSE, and
the Imatron common stock price is as reported by the Nasdaq National Market.

                              THE SPECIAL MEETING

GENERAL


    We are sending you this proxy statement/prospectus as part of a solicitation
of proxies by the board of directors of Imatron for use at the special meeting
of Imatron shareholders. We are first mailing this proxy statement/prospectus,
including a notice of the special meeting and a form of proxy, on or about
November 16, 2001.


    The special meeting is scheduled to be held on:


                               December 19, 2001
                                   10:30 a.m.


                              Embassy Suites Hotel
                             250 Gateway Boulevard
                        South San Francisco, California

PURPOSE OF THE SPECIAL MEETING

    The purpose of the special meeting is to vote on a proposal to approve and
adopt the merger agreement. As a result of the merger, each share of Imatron's
outstanding common stock will be converted into a fraction of a share of GE
common stock, and Imatron will become a wholly owned subsidiary of GE.

    We know of no other matters to be brought before the special meeting.
However, if any other matters are properly presented for action at the Imatron
special meeting, including a motion to adjourn the meeting to another time or
place, the persons named in the enclosed proxy card will have the discretion,
unless otherwise noted on any proxy form, to vote on those matters, subject to
applicable law. No proxy card that is voted against the merger will be voted in
favor of any adjournment or postponement.

RECOMMENDATION OF THE IMATRON BOARD

    Imatron's board of directors has unanimously approved the merger agreement.
IMATRON'S BOARD HAS DETERMINED THAT THE MERGER AGREEMENT IS ADVISABLE AND FAIR
TO AND IN THE BEST INTERESTS OF IMATRON AND ITS SHAREHOLDERS AND RECOMMENDS THAT
IMATRON'S SHAREHOLDERS VOTE FOR THE ADOPTION OF THE PLAN OF MERGER. See "The
Merger--Reasons for the Merger; Recommendation of the Imatron Board of
Directors."

REQUIRED VOTE

    Adoption of the plan of merger requires the affirmative vote of a majority
of the outstanding shares of Imatron common stock that vote at the special
meeting. Each share of outstanding Imatron common stock entitles its holder to
one vote.

RECORD DATE


    Imatron's board of directors has fixed the close of business on October 29,
2001 as the record date for the special meeting. At that date, there were
105,331,524 shares of Imatron common stock outstanding. Only shareholders of
record on the record date will receive notice of and be entitled to vote at the
meeting. No other voting securities of Imatron are outstanding.



    As of the record date, directors and executive officers of Imatron
beneficially owned and had the right to vote 2,242,619 shares of Imatron common
stock entitling them to exercise approximately 2.1% of the voting power of the
Imatron common stock


                                       15


    Additionally, as a condition to GE's willingness to enter into the merger
agreement, S. Lewis Meyer, Douglas P. Boyd, Terry Ross and Jose Maria Salema
Garcao have each entered into a shareholder agreement which requires them, among
other things, to vote 7,189,556 of the shares of Imatron common stock directly
owned by them in the aggregate (representing approximately 6.8% of the issued
and outstanding shares of Imatron common stock on October 29, 2001), as well as
any additional Imatron shares that they may subsequently acquire, including up
to 3,627,008 shares issuable upon exercise of warrants and stock options, in the
event of such exercise (which would represent an additional 3.4% of the issued
and outstanding shares of Imatron common stock on October 29, 2001) in favor of
approving and adopting the plan of merger at the special meeting. See "The
Shareholder Agreements."


QUORUM

    A majority of the outstanding shares of Imatron common stock entitled to
vote must be present at the special meeting, either in person, or by proxy, in
order for there to be a quorum at the special meeting. There must be a quorum in
order for the vote on the plan of merger to be held.

    We will count the following shares of Imatron common stock as present at the
special meeting for purposes of determining whether or not there is a quorum:

    - shares held by persons who attend or are represented at the Imatron
      special meeting whether or not the shares are voted; and

    - shares for which Imatron received properly executed proxies.

PROXIES

    You should complete and return the accompanying proxy card whether or not
you plan to attend the special meeting in person. All properly executed proxies
received by Imatron before the special meeting that are not revoked will be
voted at the special meeting in accordance with the instructions indicated on
the proxies or, if no direction is indicated, FOR approval of the plan of
agreement. Properly executed proxies also will be voted for any adjournment or
postponement of the Imatron special meeting for the purpose of soliciting
additional votes to approve the plan of merger, if necessary.

    Proxies marked "Abstain" will not be voted at the special meeting. In
addition, under Nasdaq rules, your broker cannot vote Imatron common shares
without specific instructions from you. You should follow the directions your
broker provides to you regarding how to instruct your broker to vote your
shares. Abstentions will have the same effect as votes against adoption of the
plan of merger. Accordingly, Imatron's board of directors urges you to complete,
date and sign the accompanying proxy card and return it promptly in the enclosed
envelope.

REVOCATION

    Your grant of a proxy on the enclosed proxy card does not prevent you from
voting in person or otherwise revoking your proxy at any time before it is voted
at the special meeting. To revoke your proxy, either:

    - deliver a signed notice of revocation or properly executed new proxy
      bearing a later date to:

                                  Imatron Inc.
                           389 Oyster Point Boulevard
                     South San Francisco, California 94080
                         Attention: Corporate Secretary

    - attend the Imatron special meeting and vote your shares in person.

                                       16

SOLICITATION OF PROXIES

    In addition to soliciting proxies by mail, officers, directors and employees
of Imatron, without receiving additional compensation, may solicit proxies by
telephone, telegraph, in person or by other means. Arrangements also will be
made with brokerage firms and other custodians, nominees and fiduciaries to
forward proxy solicitation materials to the beneficial owners of Imatron common
stock held of record by those persons, and GE and Imatron will reimburse these
brokerage firms, custodians, nominees and fiduciaries for related, reasonable
out-of-pocket expenses they incur. MacKenzie Partners, Inc., a proxy
solicitation firm, will assist Imatron in soliciting proxies and will be paid a
fee of approximately $10,000 plus out-of-pocket expenses. GE and Imatron will
share equally all expenses related to printing and filing the proxy
statement/prospectus and all the regulatory filing fees incurred in connection
with the proxy statement/prospectus. See "The Merger Agreement--Termination of
the Merger Agreement--FEES AND EXPENSES--EXPENSES."

                                       17

                                   THE MERGER

GENERAL

    The Imatron board of directors has unanimously approved the merger
agreement, which provides for the acquisition by GE of Imatron through a merger
that will result in Imatron becoming a wholly owned subsidiary of GE and you
becoming a GE stockholder. Upon completion of the merger, each share of your
Imatron stock will be converted into a fraction of a share of GE common stock,
plus cash in lieu of fractional shares. The conversion will be based on a
conversion ratio determined by dividing $1.89 by the average of the daily
volume-weighted sales prices per share of GE common stock on the NYSE for the
ten consecutive trading days ending on the trading day which is five calendar
days prior to the date on which the merger occurs and then rounding to the
nearest thousandth. The result of this equation is the fractional share of GE
common stock to be exchanged for each share of Imatron common stock. You will
have your shares aggregated and will receive whole shares of GE common stock
plus cash instead of fractional shares, if any.

BACKGROUND OF THE MERGER

    Believing that the ultimate market for non-invasive imaging of coronary
arteries and minimally invasive electron beam angiography was much larger than a
company with its limited resources could effectively commercially exploit, in
the summer of 1999 Imatron retained AmeriCal Securities, a regional investment
bank specializing in the healthcare industry, to explore potential strategic
opportunities for Imatron. Those potential strategic opportunities included
business combination transactions, private placements of Imatron equity
securities, sales of a significant number of EBT scanners to a single purchaser,
or a worldwide distribution agreement based upon a firm commitment for the
purchase of EBT scanners.

    Prior to retaining AmeriCal, in early 1998, at the American College of
Cardiology conference, S. Lewis Meyer, CEO of Imatron, and several members of
the business development group of GE Medical Systems, a division of GE, first
discussed the possibility of GE Medical Systems becoming a distributor of
Imatron scanners. As a result of those discussions, GE Medical Systems was
appointed as a non-exclusive sales representative for Imatron's products through
the execution of a Sales Representative Agreement, effective July 1, 1998.

    Also in early 1998, in connection with a pre-existing relationship with
Siemens AG, Imatron had proposed that Siemens and Imatron explore a potential
business combination prior to the scheduled March 31, 1998 expiration of
Siemen's EBT scanner distribution agreement and its agreements with Imatron
related to research and development of EBT technology. Although Siemens
expressed interest in a continuing limited distributor relationship, the
discussions ended without any agreement. Siemens did not express any further
interest in any business transactions with Imatron after March 1998.

    Following its retention in 1999, AmeriCal approached certain targeted major
pharmaceutical companies with a significant presence in the market for
cholesterol-lowering drugs as well as certain medical device companies. From the
summer of 1999 through the summer of 2000, AmeriCal contacted Pfizer, Inc.,
Bristol Myers Squibb Co., Bayer Corporation, Merck & Co., Inc., and Solvay
Pharmaceuticals, Inc. to solicit interest in a possible transaction involving
either the purchase of a significant number of Imatron EBT scanners, which would
be strategically deployed in screening centers operated by these pharmaceutical
companies, or the complete acquisition of Imatron. Although these pharmaceutical
companies appreciated the value of EBT technology as it related to the marketing
of their pharmaceutical products, none of these solicitations resulted in any
firm proposals. During the same period, AmeriCal contacted several medical
device manufacturers, including Guidant Corp., Medtronic, Inc., and Boston
Scientific Corp., to determine whether any of these companies had an interest in
an acquisition of, or strategic transaction with, Imatron. Despite extensive
discussions, those companies expressed only limited interest and ultimately
viewed the relatively high priced Imatron EBT

                                       18

scanner only as a marketing tool that could support their existing line of
medical devices and not as a primary line of business.

    Through existing relationships with executives and representatives of
Koninklijke Philips Electronics N.V., in March 2000, AmeriCal and Imatron
initiated discussions regarding a possible acquisition of Imatron or another
significant business relationship with Philips Medical Systems North America
division. These discussions led to several meetings in late 2000 and the first
half of 2001.

    In the summer of 2000, AmeriCal Securities approached GE Medical Systems
about the possibility of either forming a strategic alliance or pursing an
acquisition of Imatron by GE. Imatron generally believed that there would be
significant synergies between it and GE Medical Systems because of GE Medical
Systems' interest in developing a more extensive cardiac business and GE Medical
Systems' overall cardiovascular product line. Specifically, Imatron considered a
transaction with GE Medical Systems to be particularly advantageous to the
development and commercialization of Imatron's EBT technology because of GE
Medical Systems' commitment to, and extensive resources devoted to, GE Medical
Systems' cardiovascular business. Imatron believed these resources would
accelerate and strengthen the rapid development of Imatron's EBT technology.

    AmeriCal Securities' Richard F. Gaston, M.D., through Lewis Dudley, General
Manager of Americas CT division of GE Medical Systems, arranged a meeting
between Dr. Gaston and H. David He, Ph.D., Manager, Cardiology and Growth
Segment of GE Medical Systems, at the American Heart Association meeting in New
Orleans in November 2000. Following that introductory meeting, Imatron and GE
Medical Systems concluded that further discussions were appropriate, and Dr. He
agreed to arrange a meeting with Dow R. Wilson, General Manager, Global CT GE
Medical Systems, Mr. Meyer and Dr. He at the Radiological Society of North
America conference in November 2000 in Chicago. At that same conference, Imatron
management and AmeriCal met with members of the senior executive management of
Philips Medical Systems to continue the two companies' discussions concerning a
possible business transaction. Following the meetings in Chicago with GE Medical
Systems and Philips, both GE Medical Systems and Philips separately agreed to
conduct on-site visits to Imatron in early 2001. Subsequently, AmeriCal had
discussions with the chief executive of Philips Medical Systems North America
division, while Imatron commenced discussions with other representatives of
Philips.

    In the subsequent weeks, GE Medical Systems, Imatron and AmeriCal's Charles
Engelberg, M.D. and Dr. Gaston engaged in various phone and letter
correspondence. GE Medical Systems and Imatron executed a confidentiality
agreement on February 2, 2001, and later that month Mr. Wilson, Dr. He and Karim
Karti, Manager, Global Business Development, made an on-site visit to Imatron.
At that meeting, GE Medical Systems expressed interest in moving forward with a
possible acquisition of Imatron, and a second visit was arranged for the purpose
of conducting a more formal and extensive evaluation of Imatron's current and
future technologies.

    On February 12, 2001, Philips and Imatron entered into a Non-Disclosure
Agreement, and soon thereafter, Philips visited Imatron's facilities to conduct
an extensive due diligence review of Imatron's technology and non-public
information. After in-depth discussions concerning a possible business
combination in early 2001, Philips expressed that its preferred relationship
with Imatron was that of the exclusive worldwide distributor of Imatron EBT
scanners and as an investor in Imatron's equity securities. During the spring of
2001, Imatron negotiated the terms of a proposed distribution agreement pursuant
to which Philips would commit to purchase, on a firm basis, a substantial number
of EBT scanners and make a capital infusion of $25 million that would take the
form of a purchase of equity or debt securities, combined with advance deposits
on Imatron EBT scanners to be sold by Philips. In May 2001, Marconi Corporation
plc announced its intention to sell its Medical Systems division. Philips
indicated to Imatron at that time that it had elected to suspend further
discussions with Imatron concerning any significant transaction. Imatron's
management believed this was because Philips

                                       19

was actively engaged in acquiring the Marconi Medical Systems division. On
July 4, 2001, Philips announced its agreement to purchase Marconi's Medical
Systems unit.

    On May 10, 2001, a group from GE Medical Systems, including Mr. Wilson,
Dr. He, Mr. Karti, Armin H. Pfoh, Ph.D., Manager, CT Program, Robert Armstrong,
General Manager of CT Engineering, and Jiang Hsieh, Ph.D., Senior Scientist,
returned for a more thorough examination of Imatron's intellectual property,
technology development strategy and programs, patient database, and business
prospects. Principally based on oral comments made by GE Medical Systems'
representatives at the meeting, Imatron concluded that a transaction was not
likely because of a lack of enthusiasm for Imatron's EBT technology by GE
Medical Systems representatives and as a result, GE Medical Systems would be
unlikely to offer a price that was reflective of the value of Imatron's EBT
technology.

    After the May 10, 2001 meeting, Dr. Gaston continued to have further
communications with Mr. Wilson regarding the potential value of Imatron's EBT
technology to GE Medical Systems. In those discussions, Mr. Wilson and
Mr. Gaston decided that an additional due diligence visit to Imatron might be
helpful in moving a possible transaction ahead. On June 21, 2001, several
representatives from GE Medical Systems including Mr. Wilson, Dr. He,
Mr. Karti, Dr. Hsieh, Mr. Armstrong, Brian J. Kost, Manager, CT New Product
Programs, and Eugene Saragnese, Vice President of Global Technology Operation,
met for a full day at Imatron's headquarters. Following that meeting, AmeriCal
Securities and Imatron were notified that GE Medical Systems was prepared to
make a formal offer to purchase Imatron, subject to successful completion of a
full due diligence review of Imatron.

    On June 28, 2001, in a telephone conversation, Messrs. Wilson and Karti
indicated that GE Medical Systems would consider pursuing an acquisition of
Imatron at a purchase price of up to $2.00 per share of Imatron common stock,
subject to a more extensive diligence review. On July 5, 2001, Mr. Meyer
informed Messrs. Wilson and Karti that the offer was not acceptable. Mr. Meyer
explained that the proposed valuation was inadequate, and therefore, Imatron
could not pursue a transaction at that price.

    After renewing discussions with Imatron in July 2001, Philips requested on
August 15, 2001 that Imatron's board of directors postpone any decisions on any
definitive offer from any other offeror to give Philips additional time to
finalize its terms of the proposed distribution contract. In response to
Philips's request, Mr. Meyer agreed to use his best efforts to provide Philips
additional time to develop and present its offer.

    Throughout the first two weeks of August, negotiations between GE Medical
Systems and Imatron regarding price and other financial issues were conducted by
phone, mostly between Dr. Engelberg and Mr. Karti, which concluded in GE Medical
Systems proposing an acquisition of 100% of Imatron's common stock at a purchase
price of $2.10 per share, payable in GE stock, in a structure that GE Medical
Systems understood to be a taxable transaction. At a meeting of the Imatron
board of directors held on August 17, 2001, Dr. Engelberg made a formal
presentation in which he reported that GE Medical Systems had proposed an
acquisition at a purchase price of $2.10 per share, payable in GE stock, in a
structure that the board believed to be a tax-free reorganization. In the
presentation, Dr. Engelberg reviewed publicly available past business
combination agreements by GE Medical Systems in the medical equipment field.
Imatron's counsel then outlined for the directors their fiduciary duties with
respect to the offer. After discussion, Mr. Meyer was authorized to continue the
talks with GE Medical Systems, including negotiating an increase in price and
finalizing definitive terms, including clarifying that the transaction would be
structured as a tax-free reorganization. He was also authorized to seek other
buyers or alternative business combinations. Pursuant to this authority,
Mr. Meyer continued his discussions with Philips and GE Medical Systems.

    At that same meeting, the Imatron board of directors also considered the
need for an independent financial advisor to assist the board in evaluating the
fairness to Imatron's shareholders of any proposed transaction and, if
appropriate, to render a fairness opinion in connection with any proposed

                                       20

transaction. While AmeriCal believed that the proposed offer from GE Medical
Systems was fair and reasonable to the shareholders and recommended its
acceptance to the Imatron board of directors, AmeriCal indicated that it was not
specifically engaged to provide a formal written fairness opinion and that, as a
matter of AmeriCal's company policy, it did not provide such opinions.
Therefore, AmeriCal recommended that the board retain another investment bank to
assist the board in its evaluation of any proposed transactions and, if
requested to do so, to render a fairness opinion. As the directors believed that
obtaining an evaluation of the fairness of any proposed transaction from a well
recognized and independent investment bank would be helpful to the board in its
consideration of any offer to purchase Imatron, the Imatron board of directors
authorized Mr. Meyer to identify such an investment banking firm. On
September 10, 2001, Imatron retained Thomas Weisel Partners LLC for this
project.

    On August 23, 2001, in response to Mr. Meyer's statement that a price of
$2.10 per share in a taxable transaction would not be acceptable, Michael Jones,
General Manager of Business Development for GE Medical Systems, discussed a
proposed price of $2.20 per share with Mr. Meyer in a cash transaction that
would not qualify as a tax-free reorganization. Mr. Meyer indicated that a
transaction at that price could be acceptable, but objected to conducting any
transaction other than a tax-free reorganization because a tax-free
reorganization would facilitate gaining shareholder approval by enhancing the
value of the transaction to the individual Imatron shareholders and by allowing
them to exchange their Imatron investment into GE common stock on a tax free
basis. In the days following, Mr. Jones and Mr. Meyer had several telephone
discussions in which many different structures of the transaction were explored.
Mr. Jones explained the additional costs GE Medical Systems would incur in a tax
free reorganization, and Mr. Meyer explained that for the reasons discussed
above, a tax-free reorganization was important to the Imatron shareholders.

    During the week of August 27, 2001, Philips advised Imatron management that
it was no longer interested in pursuing a distribution agreement with Imatron
and discussions terminated. Philips explained that its recent acquisitions made
it impossible for it to pursue an additional significant strategic relationship
at that time.

    On August 31, 2001, Mr. Meyer tentatively agreed to present two pricing
possibilities for the business combination transaction to the Imatron board of
directors (in each case subject to due diligence and negotiation of a definitive
agreement): a $2.10 price per share, payable in GE shares that would qualify as
a tax-free reorganization, and a $2.20 price per share payable in cash, which
would not qualify as a tax-free reorganization. Given the status of
negotiations, and the likelihood that GE Medical Systems would be expending
considerable resources to pursue a transaction with Imatron, GE Medical Systems
requested that Imatron execute and deliver an Exclusivity Agreement. The
Exclusivity Agreement was executed by Imatron and GE Medical Systems on
August 31, 2001, and provided that until September 30, 2001, Imatron would
negotiate exclusively with GE Medical Systems and would not solicit or engage in
any business combination discussions with any party other than GE Medical
Systems. The Exclusivity Agreement did not prohibit, however, Imatron from
receiving unsolicited offers from parties other than GE Medical Systems,
provided that Imatron notified GE Medical Systems of such unsolicited offer.
Following the execution of the Exclusivity Agreement, Mr. Meyer received a
comprehensive due diligence materials request, and scheduled a formal Imatron
management presentation to representatives of GE Medical Systems for
September 5, 2001, in San Francisco. In the course of subsequent telephone
discussions that day, Mr. Karti confirmed to Mr. Meyer three alternative pricing
structures for a business combination transaction: for each share of Imatron
common stock, (i) $2.20 in cash (which would be a taxable transaction to the
Imatron shareholders); (ii) $2.20 payable in GE common stock in a taxable
transaction; and (iii) $2.10 payable in GE common stock in a tax-free
reorganization. Mr. Meyer agreed to discuss these three alternatives with the
Imatron board of directors and reported back to Mr. Karti the board's preference
for a tax-free reorganization.

                                       21

    In the afternoon of September 5, 2001, several members of the executive
management team of Imatron made presentations to representatives of GE Medical
Systems management team and arranged access to certain written financial and
other non-public information requested by GE Medical Systems in connection with
its due diligence investigation of Imatron. From September 5, 2001 through
September 10, 2001, Imatron management and its counsel met with representatives
of GE Medical Systems and its counsel and discussed certain business, personnel,
legal and financial information relating to Imatron.

    Between September 10 and 14, 2001, GE Medical Systems and Imatron and their
respective counsel extensively negotiated the terms of a definitive agreement
including, but not limited to, the break-up fee, legal and acquisition expenses
payable upon termination by Imatron of the transaction and the proposed option
to purchase 19.9% of Imatron's common stock. After several concessions,
including a reduction of the amount of GE Medical Systems' third party expenses
payable by Imatron under certain circumstances related to the termination of the
merger agreement, on September 14, 2001 GE Medical Systems advised Mr. Meyer
that it was unwilling to make further changes in the terms of the agreement and
requested that he submit the most recent draft of the merger agreement to the
Imatron board of directors for its consideration. Based on GE Medical Systems'
request, Mr. Meyer called a meeting of the board of directors for September 17,
2001 at 2:00 p.m. to present and discuss the outstanding Imatron issues with the
proposed merger agreement.

    On September 11, 2001, simultaneous terrorist attacks were directed at the
World Trade Center Towers in New York City and the Pentagon in Washington, D.C.,
resulting in catastrophic damage, loss of life and disruption to the U.S.
economy. In the wake of these attacks, the New York Stock Exchange and Nasdaq
National Market suspended trading, and transportation systems throughout the
United States suffered serious disruption. These events, along with the
continued prospect of overall weakness in the U.S. economy, caused the executive
sales team of Imatron to evaluate the consequences on Imatron's financial
condition, results of operations and prospects for Imatron's third and fourth
fiscal quarters of 2001 and future periods.

    After discussions with prospective customers and sales staff worldwide, it
was determined that the availability of private investment capital and third
party equipment financing capital necessary to complete the forecasted sales
transactions for the remainder of the calendar year could be adversely affected
by the events of September 11, 2001. Imatron also believed that its existing
customers, which planned business expansion based on the purchase of additional
EBT scanners, would re-evaluate future EBT scanner purchase requirements due to
economic uncertainty and expected reduced discretionary consumer spending. While
the precise impact could not be quantified, Imatron further believed that the
events of September 11, 2001 could also have an adverse impact on sales in 2002
and introduce a substantial element of uncertainty to the economy generally and
to the market for Imatron's products. Because of the likely consequences of the
events of September 11, 2001 and GE Medical Systems' insistence on a "material
adverse change" clause in the merger agreement that allowed GE Medical Systems
to terminate the merger agreement in the event there were material changes in
Imatron's results of operations, financial projections or forecasts between
signing and closing of the merger agreement, Imatron communicated to GE Medical
Systems that its internal sales and revenue forecasts might need to be modified.
Imatron management proceeded to review its anticipated sales for the third and
fourth quarters of 2001 in order to develop a realistic but achievable sales
projection for the remainder of the year. As a result of these forecasting
efforts, and for the purposes of the proposed agreement, GE Medical Systems was
further advised that Imatron's prior guidance to the investment community might
need to be reduced from its previously announced expectation of $80+ million in
revenue for 2001 (a 30% increase over 2000) to an estimated $71 million in
revenue for 2001 (a 14% increase over 2000). Furthermore, by September 17, 2001,
Imatron's management was considering the possibility of revising its previously
announced projection of a 50% increase in net

                                       22

operating income for fiscal year 2001 as compared to fiscal year 2000, to an
approximate 30% decrease in net operating income as compared to fiscal year
2000.

    On the morning of the scheduled September 17 board meeting, Jack Marquess,
Imatron's Vice President of Worldwide Sales, Mr. Meyer and Imatron's counsel met
with Mr. Karti and GE Medical Systems' counsel to discuss the information that
was being assembled regarding the possible need to revise sales forecasts.
Mr. Karti explained that the previously discussed $2.10 price would be
reconsidered by GE Medical Systems in light of the potential significant
decreases in sales and profitability. Despite the effective withdrawal of the
offer by GE Medical Systems, the Imatron board of directors convened its meeting
to discuss the outstanding issues in the merger agreement and in the
negotiations. Mr. Marquess attended portions of the meeting. Thomas Weisel
Partners LLC participated in portions of the meeting by videoconference phone.
First, the board discussed the current state of Imatron's business in light of
the events of September 11, 2001. Mr. Meyer provided the board with the
information regarding the preliminary reforecast of sales for the third and
fourth quarters of 2001, which was discussed with GE Medical Systems earlier
that day. Mr. Meyer reported to the board that Imatron would not be likely to
meet its projections for sales in the third and fourth fiscal quarters, and that
the entirety of the impact on the 2002 fiscal year sales could not then be
completely assessed. Mr. Marquess elaborated on the information he was receiving
from potential customers regarding their intentions to delay or postpone the
order and delivery of scanners. Second, the board considered a possible decline
in the price of Imatron stock if it failed to meet its publicly announced sales
and earnings forecasts. Third, the board considered the difficulties and risks
with respect to raising capital to support Imatron's planned technology and
product development programs, particularly in light of the economic climate
following September 11, 2001. Also, the board was cognizant of, among other
factors, Philips's recent withdrawal from discussions regarding a major
strategic transaction with Imatron. At this meeting, the directors reviewed a
written presentation regarding financial aspects of the transaction prepared by
Thomas Weisel Partners, although a detailed discussion concerning the written
presentation was not held at that meeting. Since a final price and terms had not
been agreed upon between Imatron and GE, Thomas Weisel Partners did not provide
any formal opinion of value at the meeting. Subsequently, a full presentation by
Thomas Weisel Partners of the financial aspects of the transaction was made at
the meeting of the board of directors on September 20, 2001, at which time a
discussion with the directors of Imatron was held. In addition, Imatron's
counsel thoroughly reviewed the terms of the proposed merger agreement, stock
option agreement and shareholder agreement, and reviewed its advice regarding
the fiduciary duties of the Imatron board of directors.

    On September 18, 2001, in a meeting between Mr. Karti and Mr. Meyer,
Mr. Karti stated that the potential decreased sales and profit forecast, in
addition to other matters that negatively impacted GE's views on the valuation
of Imatron, would result in approximately a $30,000,000 reduction in the value
of GE Medical Systems' acquisition offer for Imatron (or approximately $.30 per
share). Mr. Meyer indicated that such a reduction would not be acceptable to
Imatron's board of directors.

    On September 19, 2001, during a teleconference between Mr. Meyer,
Mr. Marquess, Mr. Karti and Mr. Wilson, GE Medical Systems stated a willingness
to pay $1.90 per share of Imatron common stock outstanding, payable in GE common
stock, in a transaction structured as a tax free reorganization, again subject
to Imatron's acceptance of the latest version of the merger agreement.
Mr. Meyer agreed to submit the offer to Imatron's board of directors. Over the
next two days, Mr. Karti, Mr. Meyer and counsel for GE Medical Systems and
Imatron continued to negotiate the final open issues in the merger agreement.

    In the afternoon of September 20, 2001, the Imatron board of directors met
to discuss the status of the negotiations with GE Medical Systems. Mr. Meyer
reported that, other than the remaining open issue in the merger agreement
related to a cap on Imatron's transaction costs, all other issues in the
transaction had been finalized. As of that date, GE Medical Systems' offer had
included a cap on

                                       23

transaction costs that would be incurred by Imatron in connection with the
merger. However, the sum of Imatron's transaction costs exceeded the cap.
Mr. Meyer was directed to negotiate a resolution to this matter, which could
include, if necessary, a per share merger price lower than the amount of $1.90
offered specifically reflecting the amount the transaction cost exceeded the
cap. Representatives of Thomas Weisel Partners then made a presentation
regarding the proposed financial terms of the merger, including the $1.90 per
share price, as well as a financial presentation regarding Thomas Weisel
Partners' valuation analysis of Imatron and rendered a fairness opinion based on
the projections and financial data provided by Imatron's management prior to
September 11, 2001. The Imatron board of directors discussed the effects that
the reduced sales and earnings forecast might have on the proposed financial
terms of the merger. The Imatron board of directors concluded that if the $1.90
per share offer was a fair price to the Imatron shareholders based upon
pre-September 11th projections, the $1.90 price would be more favorable to
Imatron shareholders in light of possible decreases in projected revenue and
earnings as a result of the September 11th attacks. Imatron's counsel then
reviewed the directors' fiduciary responsibilities to the Imatron shareholders,
as was discussed at the meeting earlier that week. The meeting was adjourned
with a direction to Mr. Meyer to seek conclusion to all remaining issues to the
transaction.

    On September 21, 2001, after extensive discussions between Mr. Meyer,
Mr. Karti and Dr. Engelberg, GE Medical Systems agreed that, in exchange for an
increase in the cap on Imatron's transaction costs, GE Medical Systems would
reduce its offer by $0.01 per share, and as a result GE Medical Systems
presented an offer of $1.89 payable in GE shares in a tax-free reorganization.
Mr. Meyer agreed to present that offer of $1.89 per share to the Imatron board
of directors. At the meeting of the Imatron board of directors, representatives
of Thomas Weisel Partners discussed the proposed financial terms of the merger
in light of the offer of $1.89 per share. Thomas Weisel Partners delivered its
oral opinion (which was subsequently confirmed in writing) that as of that date
and based on and subject to the assumptions, limitations and qualifications set
forth in the written opinion and explained orally, the consideration to be
received by the shareholders of Imatron pursuant to the merger agreement was
fair to such shareholders from a financial point of view. The Imatron board of
directors found the price to be fair, and that the overall terms of the
transaction were in the best interests of the Imatron shareholders. Accordingly,
upon management's recommendation, the board unanimously approved the merger
agreement and the stock option agreement in the form presented to the board
subject to such final revisions as management might approve, at the transaction
price of $1.89 per outstanding share of Imatron common stock, payable in GE
common stock based on the formula set forth in the merger agreement.

    Following the meeting, during the evening of September 21, 2001, Imatron and
GE executed the stock option agreement, Imatron, GE and Ruby Merger Corp.
executed the merger agreement, and GE and S. Lewis Meyer, Jose Maria Salema
Garcao, Terry Ross and Douglas P. Boyd executed the shareholder agreement. The
proposed merger was publicly announced prior to the opening of trading on
September 24, 2001, at which time Imatron also revised its guidance to the
investment community regarding projected 2001 results of operations.

RECOMMENDATION OF THE IMATRON BOARD OF DIRECTORS; REASONS FOR THE MERGER

    At a meeting held on September 21, 2001, the board of directors of Imatron
unanimously approved and adopted the merger agreement and plan of merger,
approved the merger and determined that the merger is advisable and fair to and
in the best interests of Imatron and its shareholders. The

                                       24

Imatron board unanimously recommends adoption of the merger agreement by Imatron
shareholders. The recommendation of the Imatron board is based on a number of
factors including the following:

    - THE IMPACTS OF IMATRON'S NEED FOR SIGNIFICANT ADDITIONAL CAPITAL TO
      OPERATE AND COMPETE, AND CURRENT MARKET CONDITIONS AFFECTING ACCESS TO
      CAPITAL, INCLUDING:

       - the limited ability of Imatron, based on forecasted levels of sales
         revenues, to produce sufficient internally generated capital to support
         the aggressive technology, marketing and product development programs
         required in an environment of increased competition and changing
         technologies;

       - the possibility that, absent additional capital from outside sources,
         current development programs would likely have to be curtailed or even
         eliminated in order to assure continued Imatron operations;


       - the threat to Imatron's ability to compete successfully in an
         increasingly competitive marketplace for its products and services
         where there are several competitors, including GE, who possess greater
         financial resources and lower cost structures than Imatron;


       - current industry, economic, market and other conditions, including the
         increased volatility and uncertainty in the economy and financial
         markets decreasing the ability of Imatron's customers to finance
         purchases of scanners and owning and operating such scanners; and

       - the risk of material dilution to Imatron's existing shareholders in the
         event substantial capital could be raised.

    - THE LACK OF VIABLE STRATEGIC ALTERNATIVES, INCLUDING:

       - the limited number of potential acquirers of Imatron, the thoroughness
         and breadth of the pursuit of potential purchasers, and the lack of any
         other viable offers being produced during the two year engagement of
         AmeriCal Securities; and

       - the termination by Philips of its interest in completing and entering
         into a major distribution agreement for Imatron's products.

    - THE RELATIVE STRENGTH OF GE AND THE FINANCIAL TERMS OF THE DEAL,
      INCLUDING:

       - information, analysis and presentations with respect to the financial
         condition, results of operations and sales, and prospects for Imatron
         and GE, comparatively both historically and on a prospective basis,
         including the risks associated with the current and likely future
         economic uncertainty relating to the September 11 attacks and
         subsequent events;

       - the presentations from and discussions with Thomas Weisel Partners, and
         the written opinion of Thomas Weisel Partners (a copy of which is
         attached as Annex B to this proxy statement/prospectus) that as of the
         date thereof and based on and subject to the assumptions, limitations
         and qualifications included in the written opinion the consideration to
         be received by the shareholders of Imatron pursuant to the merger
         agreement was fair to such shareholders from a financial point of view;

       - the trading prices of Imatron common stock and the trading volume of
         Imatron common stock compared to the trading prices and volume of GE
         common stock; and

       - the opportunity for Imatron shareholders to become shareholders of GE,
         which the Imatron board of directors viewed as a highly diversified
         corporation and with an extremely liquid common stock and a solid
         history of rewarding shareholders with dividends.

                                       25

    - OTHER SPECIFIC TERMS OF THE MERGER AGREEMENT, INCLUDING:

       - Imatron's right and ability to consider other proposals and the fact
         that the deal protections proposed by GE would not preclude other
         offers;

       - the structure of the merger, which is intended to permit Imatron
         shareholders to exchange their Imatron common stock for GE common stock
         on a tax-free basis, except to the extent they receive cash for
         fractional interests; and

       - the certainty of receiving a fixed value of GE stock, regardless of
         stock market fluctuations prior to the closing of the merger.

    - POTENTIAL STRATEGIC AND OTHER BENEFITS OF THE MERGER, INCLUDING:

       - the strategic and other benefits of the merger that would combine the
         EBT technology of Imatron with the substantial resources and
         distribution channels of GE Medical Systems to give access to EBT
         technology to the millions of people who could benefit from the
         quantification of calcium in the coronary arteries as an aid in
         diagnosis of pre-clinical coronary artery disease and other unique
         clinical applications of EBT technology;

       - the opportunity for Imatron shareholders to continue their investment
         in Imatron's EBT technology by exchanging their Imatron shares for GE
         shares; and

       - the interests of constituencies other than the Imatron shareholders,
         such as employees, customers and suppliers.

    The Imatron board did not find it necessary to and did not quantify or
otherwise assign relative weights to the foregoing factors or determine that any
factor was of particular importance. Rather, the Imatron board views its
recommendation as being based on the totality of the information presented to
and considered by it.

OPINION CAREFULLY IN ITS ENTIRETY FOR THE ASSUMPTIONS MADE, THE PROCEDURES
FOLLOWED, THE MATTERS CONSIDERED AND THE LIMITS OF THE REVIEW MADE BY THOMAS
WEISEL PARTNERS IN CONNECTION WITH ITS OPINION.

OPINION OF THOMAS WEISEL PARTNERS LLC

    In September 2001, the Board of Directors of Imatron Inc. hired Thomas
Weisel Partners LLC to render a fairness opinion in connection with its merger
with Ruby Merger Corp., a subsidiary of General Electric Corporation. Thomas
Weisel Partners is a nationally recognized merchant bank specializing in
advising and investing in companies participating in the growth sectors of the
economy including: health care, technology, consumer, business services and
telecommunications. On September 21, 2001, Thomas Weisel Partners delivered to
Imatron's Board of Directors its oral opinion that, as of that date, the merger
consideration to be received by Imatron shareholders (other than General
Electric and Ruby Merger Corp.) in connection with the merger was fair to the
shareholders from a financial point of view. Thomas Weisel Partners later
delivered its written opinion dated September 21, 2001, confirming its oral
opinion.

    Imatron negotiated the consideration to be received by its shareholders in
the merger with General Electric. Imatron did not impose any limitations on
Thomas Weisel Partners with respect to the investigations made or procedures
followed in rendering its opinion. Further, Imatron did not request the advice
of Thomas Weisel Partners with respect to alternatives to the merger, and Thomas
Weisel Partners did not assist Imatron in soliciting indications of interest
from third parties for all or any part

                                       26

of Imatron or advise Imatron with respect to alternatives to the merger or
Imatron's underlying decision to proceed with or effect the merger.

PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS IN THE SCOPE OF THE
REVIEW UNDERTAKEN BY THOMAS WEISEL PARTNERS IN DELIVERING ITS OPINION, IS
ATTACHED HERETO AS ANNEX B TO THIS PROXY STATEMENT/PROSPECTUS. YOU SHOULD READ
THIS OPINION CAREFULLY AND IN ITS ENTIRETY. THE FOLLOWING DESCRIPTION OF THE
THOMAS WEISEL PARTNERS OPINION IS ONLY A SUMMARY OF THE WRITTEN OPINION AND IS
QUALIFIED BY AND NOT A SUBSTITUTE FOR THE WRITTEN OPINION.


    THOMAS WEISEL PARTNERS HAS DIRECTED ITS OPINION TO THE IMATRON BOARD OF
DIRECTORS. THE OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO YOU AS TO HOW YOU
SHOULD VOTE WITH RESPECT TO THE MERGER. THE OPINION ADDRESSES ONLY THE FINANCIAL
FAIRNESS OF THE CONSIDERATION TO BE RECEIVED BY IMATRON SHAREHOLDERS. IT DOES
NOT ADDRESS THE RELATIVE MERITS OF THE MERGER OR ANY ALTERNATIVES TO THE MERGER.
FURTHER, IT DOES NOT ADDRESS IMATRON'S UNDERLYING DECISION TO PROCEED WITH OR
EFFECT THE MERGER, OR ANY OTHER ASPECT OF THE MERGER. IN FURNISHING ITS OPINION,
THOMAS WEISEL PARTNERS DID NOT ADMIT THAT IT IS AN EXPERT WITHIN THE MEANING OF
THE TERM "EXPERT" AS USED IN THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER, NOR DID
IT ADMIT THAT ITS OPINION CONSTITUTES A REPORT OR VALUATION WITHIN THE MEANING
OF SECTION 11 OF THE SECURITIES ACT. THE THOMAS WEISEL PARTNERS OPINION INCLUDES
STATEMENTS TO THIS EFFECT.

    In connection with its opinion, Thomas Weisel Partners:

    (1) reviewed certain publicly available financial and other data with
       respect to Imatron and General Electric, including the consolidated
       financial statements for the most recent year ending December 31, 2000
       and the interim periods ending June 30, 2001 and certain other relevant
       financial and operating data relating to Imatron and General Electric
       made available to Thomas Weisel Partners from published sources and from
       the internal records of Imatron;

    (2) reviewed the financial terms and conditions of the draft dated
       September 20, 2001 of the merger agreement;

    (3) reviewed certain publicly available information concerning the stock
       market trading history for General Electric common stock and Imatron
       common stock;

    (4) compared Imatron and General Electric from a financial point of view
       with certain other companies in the medical equipment industry which
       Thomas Weisel Partners deemed to be relevant;

    (5) considered the financial terms, to the extent publicly available, of
       selected recent business combinations of companies in the medical
       equipment industry which Thomas Weisel Partners deemed to be comparable,
       in whole or in part, to the merger;

    (6) reviewed and discussed with representatives of the management of Imatron
       certain information of a business and financial nature regarding Imatron,
       furnished to Thomas Weisel Partners by them, including financial
       forecasts and related assumptions of Imatron;


    (7) made inquiries regarding and discussed the merger and the merger
       agreement and other matters related thereto with Imatron's counsel; and


    (8) performed such other analyses and examinations as Thomas Weisel Partners
       deemed appropriate.

                                       27

    In preparing its opinion, Thomas Weisel Partners did not assume any
responsibility to independently verify the information referred to above.
Instead, with Imatron's consent, Thomas Weisel Partners relied on the
information being accurate and complete in all material respects. Thomas Weisel
Partners also made the following assumptions, in each case with Imatron's
consent:

       - that the financial forecasts for Imatron provided to Thomas Weisel
         Partners by Imatron's management, have been reasonably prepared on
         bases reflecting the best available estimates and judgments of
         Imatron's management at the time of preparation as to the future
         financial performance of Imatron and that they provide a reasonable
         basis upon which Thomas Weisel Partners could form its opinion;

       - that there have been no material changes in Imatron's or General
         Electric's assets, financial condition, results of operations, business
         or prospects since the respective dates of their last financial
         statements made available to Thomas Weisel Partners, except to reflect
         changes which were publicly disclosed by General Electric;

       - that the merger will be consummated in a manner that complies in all
         respects with the applicable provisions of the Securities Act, the
         Securities Exchange Act of 1934 and all other applicable federal and
         state statutes, rules and regulations; and

       - that the merger will be consummated in accordance with the terms
         described in the draft dated September 20, 2001 of the merger
         agreement, without any further amendments thereto, and without waiver
         by Imatron of any of the conditions to its obligations thereunder.

    In addition, for purposes of its opinion:

       - Thomas Weisel Partners relied on advice of counsel and independent
         accountants to Imatron as to all legal and financial reporting matters
         with respect to Imatron, the merger and the merger agreement.

       - Thomas Weisel Partners did not assume responsibility for making an
         independent evaluation, appraisal or physical inspection of the assets
         or liabilities (contingent or otherwise) of Imatron or General
         Electric, nor was Thomas Weisel Partners furnished with any of these
         appraisals.

       - Imatron's management informed Thomas Weisel Partners, and Thomas Weisel
         Partners assumed, that the merger would be recorded as a purchase
         transaction under GAAP.

       - Thomas Weisel Partners based its opinion on economic, monetary and
         market and other conditions as in effect on, and the information made
         available to Thomas Weisel Partners as of, the date of its opinion.
         Since Thomas Weisel Partners' opinion was rendered during a period of
         significant and uncommon volatility in the capital markets, it is
         subject to the absence of further material changes in economic,
         monetary and market and other conditions from those existing on the
         date of the opinion. Accordingly, although subsequent developments may
         affect its opinion, Thomas Weisel Partners has not assumed any
         obligation to update, revise or reaffirm its opinion.

    The following represents a brief summary of the material financial analyses
performed by Thomas Weisel Partners in connection with providing its opinion to
the board of directors of Imatron. Some of the summaries of financial analyses
performed by Thomas Weisel Partners include information presented in tabular
format. In order to fully understand the financial analyses performed by Thomas
Weisel Partners, you should read the tables together with the text of each
summary. The tables alone do not constitute a complete description of the
financial analyses. Considering the data set forth in the tables without
considering the full narrative description of the financial analyses, including
the

                                       28

methodologies and assumptions underlying the analyses, could create a misleading
or incomplete view of the financial analyses performed by Thomas Weisel
Partners.

    DISCOUNTED CASH FLOW ANALYSIS.  Thomas Weisel Partners used financial cash
flow forecasts of Imatron for calendar years 2002 and 2003, as estimated by
Imatron's management, and financial cash flow forecasts of Imatron for calendar
years 2004 through 2006, as estimated by Thomas Weisel Partners based on
conversations with Imatron's management regarding the historical performance of
Imatron and management's expectations for the future performance of Imatron, to
perform a discounted cash flow analysis. In conducting this analysis, Thomas
Weisel Partners assumed that Imatron would perform in accordance with these
forecasts. Thomas Weisel Partners first estimated the terminal value of the
projected cash flows by applying multiples to Imatron's estimated earnings
before interest, taxes, depreciation and amortization (EBITDA), which multiples
ranged from 15.0x to 20.0x. Thomas Weisel Partners then discounted the cash
flows projected through 2006 and the terminal values to present values using
rates ranging from 11.0% to 13.0%. Using a discount rate of 12.0% (which is the
midpoint between 11.0% and 13.0%), this analysis indicated a range of enterprise
values (defined as equity value plus total debt less cash and cash equivalents),
which were then reduced by Imatron's estimated net debt (defined as total debt
less cash and cash equivalents), to calculate a range of equity values. The
indicated range of equity values based on this analysis were $174 million to
$218 million. Thomas Weisel Partners noted that the value of stock consideration
to be received by Imatron shareholders was $203 million.

    PRECEDENT TRANSACTIONS ANALYSIS.  Based on public and other available
information, Thomas Weisel Partners calculated the multiples of enterprise value
to LTM (defined, with respect to each transaction (including the merger), as the
last 12 months ended on the last day of the calendar quarter prior to the
calendar quarter in which such transaction was announced) revenue and LTM EBITDA
and the multiple of equity value to LTM net income, for Imatron implied in the
following 10 comparable precedent acquisitions of medical equipment companies
that have been announced since January 1, 1997:

                                       29

    The comparable transaction analysis indicated a range of enterprise values,
which were then reduced by Imatron's estimated net debt, to calculate a range of
equity values. The indicated range of equity values based on this analysis were
$135 million to $220 million. Thomas Weisel Partners noted that the value of
stock consideration to be received by Imatron shareholders was $203 million.

    ONE DAY PREMIUMS PAID ANALYSIS.  Thomas Weisel Partners reviewed the
premiums paid by acquirers in selected medical equipment transactions to the
closing price one day prior to the announcement of each transaction. The
transactions selected were those with an implied target enterprise value between
one hundred million and five hundred million dollars.

 Transactions with Implied Target Company Enterprise Value between $100 million
                                and $500 million

    The range of premiums paid by acquirers to the closing stock price one-day
prior to the announcement of each transaction was compared with the implied
premium to be paid by General Electric for Imatron in the merger as follows:



PREMIUM PAID IN SELECTED
COMPARABLE TRANSACTIONS                        RANGE OF PREMIUMS    PROPOSED MERGER
------------------------                       ------------------   ---------------
                                                              
One Day Prior................................  15.0 -- 25.0%        26.8      %


    The premiums paid analysis indicated a range of enterprise values, which
were then reduced by Imatron's estimated net debt, to calculate a range of
equity values. The indicated range of equity values

                                       30

based on this analysis were $184 million to $200 million. Thomas Weisel Partners
noted that the value of stock consideration to be received by Imatron
shareholders was $203 million.

    PUBLIC MARKET COMPARABLES ANALYSIS.

    Thomas Weisel Partners compared the valuation multiples implied by the
merger to those of selected publicly-traded medical equipment companies. Since
there are no directly comparable publicly-traded companies, Thomas Weisel
Partners analyzed companies with similar business models in two areas:
Cardiovascular and Diversified equipment manufacturers. In so doing, Thomas
Weisel Partners did not attach any weight to any category. The companies
included in each category are:




           CARDIOVASCULAR                           DIVERSIFIED
-------------------------------------  -------------------------------------
                                    
Boston Scientific                      Integra Lifesciences
St. Jude Medical                       Vital Signs
Thoratec Corp.                         ICU Medical
Abiomed
Zoll Medical
Closure Medical
Novoste



    For each of these companies, Thomas Weisel Partners calculated the multiple
of enterprise value to estimates of total revenue and EBITDA for the fiscal year
2001 and equity value to estimates of net income before goodwill for 2001. For
purposes of this analysis, Thomas Weisel Partners calculated equity value on the
basis of closing stock prices on September 20, 2001. Estimated revenues for the
comparable companies were derived from equity research reports published by
investment banks. Thomas Weisel Partners then compared the mean and median
multiples of enterprise value to revenue and EBITDA estimates for fiscal year
2001 and the mean and median multiples of equity value to net income before
goodwill to the multiples of Imatron implied by the consideration to be received
in the merger.

    The following table sets forth the multiples indicated by this analysis:



ENTERPRISE VALUE TO:                             RANGE OF MULTIPLES    PROPOSED MERGER
--------------------                            --------------------   ---------------

2001 Net Income...............................  20.0x -- 30.0x              27.5x


    The comparable companies analysis indicated a range of enterprise values,
which were then reduced by Imatron's estimated net debt, to calculate a range of
equity values. The indicated range of equity values based on this analysis were
$137 million to $219 million. Thomas Weisel Partners noted that the value of
stock consideration to be received by Imatron shareholders was $203 million.

    No company or transaction used in the comparable company or comparable
transactions analyses is identical to Imatron or the merger. Accordingly, an
analysis of the results of the foregoing is not mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors that
could affect the public trading value of the companies to which Imatron and the
merger are being compared.

    While the comparable company analysis compared Imatron to ten companies in
the medical equipment industry, Thomas Weisel Partners did not include every
company that could be deemed to be a participant in this same industry, or in
the specific sectors of this industry.

                                       31

    PROJECTED SHARE PRICE ANALYSIS.  Thomas Weisel Partners projected Imatron's
share price based on the Company's projected earnings per share for 2001 and
2002 and the Company's current price to earnings multiple. The current price to
earnings multiple was computed by dividing Imatron's September 20, 2001 closing
share price of $1.49 by management's 2001 earnings per share estimate of $0.07,
resulting in a price to earnings ratio of 21.5x. Thomas Weisel Partners
calculated Imatron's CY2002 share price by multiplying management's 2002
earnings per share estimate of $0.05 by the current trading multiple of 21.5x,
resulting in an estimated stock price of $1.14 per share. Thomas Weisel Partners
noted that the value of stock consideration to be received by Imatron
shareholders in this transaction is $1.89 per share.

    The foregoing description is only a summary of the analyses and examinations
that Thomas Weisel Partners deems material to its opinion. It is not a
comprehensive description of all analyses and examinations actually conducted by
Thomas Weisel Partners. The preparation of a fairness opinion necessarily is not
susceptible to partial analysis or summary description. Thomas Weisel Partners
believes that its analyses and the summary set forth above must be considered as
a whole and that selecting portions of its analyses and of the factors
considered, without considering all analyses and factors, would create an
incomplete view of the process underlying the analyses set forth in its
presentation to the board of directors of Imatron. In addition, Thomas Weisel
Partners may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions. The fact that any specific analysis has been referred to in
the summary above is not meant to indicate that this analysis was given greater
weight than any other analysis. Accordingly, the ranges of valuations resulting
from any particular analysis described above should not be taken to be the view
of Thomas Weisel Partners with respect to the actual value of Imatron.

    In performing its analyses, Thomas Weisel Partners made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of Imatron. The analyses
performed by Thomas Weisel Partners are not necessarily indicative of actual
values or actual future results, which may be significantly more or less
favorable than those suggested by these analyses. These analyses were prepared
solely as part of the analysis performed by Thomas Weisel Partners with respect
to the financial fairness of the merger consideration to be received by Imatron
shareholders pursuant to the merger, and were provided to Imatron in connection
with the delivery of the Thomas Weisel Partners opinion. The analyses do not
purport to be appraisals or to reflect the prices at which a company might
actually be sold or the prices at which any securities may trade at any time in
the future.

    As described above, Thomas Weisel Partners' opinion and presentation were
among the many factors that the board of directors of Imatron took into
consideration in making its determination to approve, and to recommend that the
shareholders of Imatron approve, the merger.

    Imatron has agreed to pay Thomas Weisel Partners a fee of $1 million upon
delivery of its opinion. Further, Imatron has agreed to reimburse Thomas Weisel
Partners for its reasonable out-of-pocket expenses and to indemnify Thomas
Weisel Partners, its affiliates, and their respective partners, directors,
officers, agents, consultants, employees and controlling persons against
specific liabilities, including liabilities under the federal securities laws.

                                       32

    In the ordinary course of its business, Thomas Weisel Partners actively
trades the equity securities of Imatron and General Electric for its own account
and for the accounts of customers and, accordingly, may at any time hold a long
or short position in these securities.

INTERESTS OF CERTAIN PERSONS IN THE MERGER; CONFLICTS OF INTEREST

    In considering the merger, you should be aware of the interests executive
officers and directors of Imatron have in the merger that are different from
your interests as shareholders. In this regard, you should consider, among other
things, the stock option modifications and the agreements described below.

    STOCK OPTIONS.  The vesting of all Imatron stock options will be accelerated
immediately prior to the effective time of the merger, and will be cancelled.
Just prior to such cancellation, each outstanding Imatron stock option that has
an exercise price less than $1.89 will be converted into a right to receive the
number of shares of GE common stock (with cash in lieu of fractional shares)
determined by multiplying the number of shares of Imatron common stock subject
to such Imatron stock option immediately prior to the merger by an amount equal
to the product of (A) a fraction, the numerator of which is $1.89 minus the sum
of (i) the exercise or purchase price of the Imatron stock option per share and
(ii) all taxes required to be held in connection with the stock option per
share, and the denominator of which is $1.89, and (B) the amount determined by
dividing $1.89 by the average of the daily volume-weighted sales prices per
share of GE common stock on the NYSE for the ten consecutive trading days ending
on the trading day which is five calendar days prior to the closing of the
merger.

    Each Imatron stock option that has an exercise price equal to or greater
than $1.89 per share will terminate. However, each holder of Imatron stock
options who will be continuing as an employee of GE after the merger will be
offered the opportunity to waive their rights to these out-of-the-money options
in exchange for options to purchase GE common stock. The GE stock options will
be granted under GE's existing stock option plan and be subject to GE's
customary terms and conditions, except that

    - the number of shares subject to the new GE stock options will be equal to
      the number of shares subject to the terminated Imatron stock options,
      multiplied by the exchange ratio;

    - the exercise price of the new GE stock options will be equal to the
      exercise price of the terminated Imatron stock options divided by the
      exchange ratio; and

    - the vesting schedule for the new GE stock options will approximate the
      vesting schedule for the terminated Imatron stock options (without giving
      effect to any acceleration in connection with the merger), except that
      future vesting will occur only in September of each subsequent calendar
      year.

    The following table indicates for each person who is one of Imatron's
current executive officers or directors and who holds stock options:

    - the number of shares of Imatron's common stock subject to those options
      with an exercise price less than $1.89 as of October 29, 2001 ("In the
      Money");

    - the number of shares of Imatron's common stock subject to those options
      with an exercise price equal to or greater than $1.89 as of October 29,
      2001 ("Out of the Money");

    - the aggregate value, net of the exercise price and before any applicable
      taxes, for "In the Money" options based on a per share price of $1.89;


    - the number of GE shares to be received in exchange for In the Money
      Imatron options in the merger based on a hypothetical exchange ratio of
      0.049; and


                                       33


    - the number of shares of GE stock subject to new GE stock options as a
      result of Out of the Money options, in the event such person continues as
      an employee of GE after the merger, based on a hypothetical exchange ratio
      of 0.049.

------------------------


(1) The number of GE shares in this column is estimated based on a GE per share
    price of $38.77 which was the closing price of GE common stock on
    November 5, 2001 resulting in a hypothetical exchange ratio of 0.049.



(2) Under Mr. Meyer's Separation Agreement, he will not continue as an employee
    of GE after the merger. See "--Separation Agreements".


    RETENTION AGREEMENTS.  After consultation with GE and after the execution of
the merger agreement but before the closing, Imatron plans to enter into
retention agreements with certain executive officers of Imatron. These
agreements become effective when the merger occurs, but if the merger agreement
is terminated, the retention agreements will terminate. The retention agreements
are intended to induce these executives to remain employed by Imatron. Under
each agreement, the executive officer will be paid a retention bonus if the
executive officer remains in the employ of GE for a period of one year following
the effective time of the merger. Each such person will also receive a
termination fee (an amount equal to the retention bonus) if terminated other
than for "cause" as defined in the retention agreements, if permanently
disabled, and in other related circumstances. Each executive officer has also
agreed to confidentiality and non-competition covenants which survive
termination of the retention agreements.

    The Imatron directors and officers who have executed or will be asked to
execute retention agreements, each such person's potential retention payment and
termination payment are listed below:




                                                                RETENTION AND

    SEPARATION AGREEMENTS.  On September 21, 2001, in order to induce GE to
execute the merger agreement, Imatron and S. Lewis Meyer executed a separation
agreement. Under this agreement, Mr. Meyer's employment with Imatron will
terminate at the effective time of the merger. As a result, Imatron will pay to
Mr. Meyer $464,450, half of which is due within 5 days of such termination (but
not before January 3, 2002) and the remainder of which is due one year following
the initial payment. In addition, Imatron will forgive a promissory note of up
to $112,500, and will pay Mr. Meyer $50,000 that was anticipated to be paid
under Imatron's bonus plan. Mr. Meyer's stock options will be afforded the same
treatment as other Imatron option holders who will not be employees of GE
following the merger (that is, they will be exchanged for shares of GE stock to
the extent their exercise price is below $1.89 per share), except that he will
not be offered any GE stock options. In return, Mr. Meyer has agreed, among
other things, to not compete with the business of Imatron for one year following
termination, and to release Imatron of any claims he has as of the date of
termination. Mr. Meyer and GE also discussed whether entering into a consulting
agreement following the merger agreement would be in the parties' best interest.
However, no agreement regarding consulting services was reached.


    If terminated, Frank Cahill, by an offer letter given to him in 1999, is
entitled to severance and continued benefits for six months after the date of
termination.

    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.  The merger agreement
provides that, after the merger, GE will, as permitted by law, indemnify persons
who were Imatron's directors or officers immediately before the merger who
suffer liabilities or losses from any threatened or actual claim or proceeding
based on the merger agreement or on the fact that the person was a Imatron
director or officer. The merger agreement further allows Imatron to purchase
"tail" coverage under a director and officer liability insurance policy for the
people who were Imatron officers and directors immediately prior to the merger
for a period not to exceed six years from the merger. See "THE MERGER
AGREEMENT--Covenants and Agreements--INDEMNIFICATION; DIRECTORS' AND OFFICERS'
INSURANCE"

PROCEDURES FOR EXCHANGE OF IMATRON COMMON STOCK CERTIFICATES

    GE will deposit with its exchange agent, certificates representing the
shares of GE common stock and cash instead of any fractional shares that would
otherwise be issued to shareholders under the merger agreement in exchange for
the outstanding shares of Imatron common stock.

    As soon as practicable after the merger occurs, the exchange agent will mail
to Imatron shareholders a letter of transmittal. The letter of transmittal will
contain instructions for the surrender of certificates representing Imatron
common stock.

    PLEASE DO NOT RETURN IMATRON COMMON STOCK CERTIFICATES WITH THE ENCLOSED
PROXY AND DO NOT FORWARD YOUR CERTIFICATES TO THE EXCHANGE AGENT UNLESS AND
UNTIL YOU HAVE RECEIVED A LETTER OF TRANSMITTAL FOLLOWING THE MERGER.

    Upon surrender of the certificates representing Imatron common stock after
the merger, you will be paid cash instead of any fractional shares of GE common
stock you would otherwise receive. The amount of cash you receive instead of a
fractional share will be equal to:

    - the fraction of a share you would otherwise receive, multiplied by

    - the average of daily volume weighted prices per share of GE common stock
      sold during the ten-day trading period which ends on the trading day five
      calendar days prior to the close of the merger.

    GE will pay dividends or other distributions declared on GE common stock
only after the merger has occurred and after you have surrendered your Imatron
certificates.

    If a certificate for Imatron common stock has been lost, stolen or
destroyed, the exchange agent will issue your shares of GE common stock and any
cash instead of a fractional share only after you have delivered an affidavit as
to the loss, theft or destruction of the certificate and as to your

                                       35

ownership of the certificate. Imatron or the exchange agent may require you to
post a bond in an amount as GE or the exchange agent may determine is necessary
as an indemnity against any claim that may be made against GE with respect to
the lost, stolen or destroyed certificate.

ANTICIPATED ACCOUNTING TREATMENT

    GE will account for the merger under the "purchase" method of accounting in
accordance with generally accepted accounting principles. Therefore, the total
merger consideration paid by GE in connection with the merger, together with the
direct costs of the merger, will be allocated to Imatron's assets and
liabilities based on their fair market values with any excess being treated as
goodwill. The assets and liabilities and results of operations of Imatron will
be consolidated into the assets and liabilities and results of operations of GE
after the merger.

CHANGES IN STOCK RIGHTS

    If we complete the merger, Imatron common stock will stop trading on the
Nasdaq National Market. In addition, Imatron will deregister the Imatron common
stock under the Securities Exchange Act of 1934, and, accordingly, will no
longer file periodic reports.

    After the merger, shareholders of Imatron will become stockholders of GE.
After the merger, the rights of all former shareholders of Imatron will be
governed by applicable New York law (instead of the New Jersey corporate law),
including the New York corporate law, and by the certificate of incorporation
and bylaws of GE. For a description of the differences between the rights of GE
and Imatron shareholders, see "Comparison of Rights of Imatron Shareholders and
GE Stockholders."

FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

    GE and Imatron have made forward-looking statements in this proxy
statement/prospectus and the documents to which we have referred you that are
subject to risks and uncertainties. These forward-looking statements represent
expectations or beliefs of GE and Imatron concerning future events, and we
cannot assure you that the results described will be achieved. Forward-looking
statements include information concerning possible or assumed future results of
operations of GE and Imatron set forth under "Reasons for the Merger;
Recommendation of the Imatron Board of Directors" and "Opinion of Thomas Weisel
Partners LLC." Forward-looking statements can generally be identified by the use
of the words "believes," "expects," "anticipates," "projects," "foresee,"
"will," or similar expressions.

    GE and Imatron caution you that these forward-looking statements are subject
to risks, uncertainties and other factors, many of which are outside of our
control. Our actual results may therefore differ from those forward-looking
statements. Such risks and uncertainties include, among other things:

    - material adverse changes in economic conditions and in the markets served
      by GE and Imatron;

    - the loss of consumer confidence by Imatron's existing customers;

    - the resulting economic impact of the events of September 11, 2001 and any
      potential future military or other conflict;

    - regulatory, legal, economic and other changes in the healthcare industry
      generally;

    - a significant delay in the expected completion of the merger;

    - competitive pressures;

    - GE's and Imatron's ability to attract and retain key personnel;

    - changes in the financial condition of Imatron customers;

    - variability of quarterly results;

                                       36

    - uncertainty of entrance into new markets; and

    - integration of the acquired business.

    Forward-looking statements are not guarantees of performance. By their
nature, they involve risks, uncertainties and assumptions. You are cautioned not
to put undue reliance on any forward-looking statement. Any such statement
speaks only as of the date of this proxy statement/prospectus, and we do not
have any intention or obligation to revise or update forward-looking statements,
even if new information, future events, or other circumstances have made them
incorrect or misleading.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

    The following discussion is a summary of material income tax consequences of
the merger. This discussion is based on the Internal Revenue Code, the related
Treasury regulations promulgated thereunder, existing administrating
interpretations and court decisions, all of which are subject to change,
possibly with retroactive effect. Any such change could affect the accuracy of
the statements and the conclusions discussed herein and the tax consequences of
the merger to GE, Imatron and Ruby Merger Corp. This discussion also assumes
that Imatron shareholders hold their shares of Imatron common stock as capital
assets within the meaning of Section 1221 of the Internal Revenue Code. No
attempt has been made to comment on all federal income tax consequences of the
merger that may be relevant to particular holders, including holders that are
subject to special tax rules. Some examples of holders that are subject to
special tax rules are:

    - dealers in securities;

    - financial institutions;

    - insurance companies;

    - tax-exempt organizations;

    - holders of shares of Imatron stock as part of a position in a "straddle"
      or as part of a "hedging" transaction;

    - holders who have a "functional currency" other than the U.S. dollar;

    - holders who are foreign persons; and

    - holders who acquired their shares of Imatron stock through stock option or
      stock purchase programs or otherwise as compensation.

    In addition, we are not addressing any consequences arising under the laws
of any state, local or foreign jurisdiction. IMATRON SHAREHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS AS TO SPECIFIC TAX CONSEQUENCES TO THEM OF THE
MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN
TAX LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.

    The obligations of Imatron and GE to complete the merger are conditioned
upon the delivery of opinions to GE from Gibson, Dunn & Crutcher LLP and to
Imatron from Allen Matkins Leck Gamble & Mallory LLP, in each case substantially
to the effect that, for federal income tax purposes, the merger will constitute
a "reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code, and Imatron, Ruby Merger Corp. and GE will each be a party to that
reorganization within the meaning of Section 368(b) of the Internal Revenue
Code. These opinions of counsel will be given in reliance on representations and
covenants including those contained in certificates executed by officers of
Imatron, GE and others. These opinions are not binding on the courts or the
Internal Revenue Service, nor do they preclude the Internal Revenue Service from
adopting a position contrary to that expressed in the opinions. No assurance can
be given that contrary positions will not successfully be asserted by the
Internal Revenue Service or adopted by a court if the issues are litigated.
Neither Imatron nor GE intends to obtain a ruling from the Internal Revenue
Service with respect to the federal income tax consequences of the merger.

                                       37

    Assuming that the merger qualifies as a reorganization under Section 368(a)
of the Internal Revenue Code, the following material federal income tax
consequences will result from the Merger:

    - none of GE, Ruby Merger Corp. or Imatron will recognize any gain or loss
      solely as a result of the merger;

    - the shareholders of Imatron will not recognize any gain or loss upon the
      exchange of their shares of Imatron common stock for shares of GE common
      stock pursuant to the merger, except with respect to any gain or loss
      attributable to cash received instead of fractional shares of GE common
      stock;

    - the aggregate tax basis of the shares of GE common stock received in
      exchange for shares of Imatron common stock pursuant to the merger
      (including a fractional share of GE common stock for which cash is paid)
      will be the same as the aggregate tax basis of the shares of Imatron
      common stock surrendered in the merger;

    - the holding period for shares of GE common stock received in exchange for
      shares of Imatron common stock pursuant to the merger will include the
      holding period for the Imatron common stock surrendered in exchange
      therefor; and

    - cash payments received by Imatron shareholders instead of a fractional
      share of GE common stock will be treated as received in exchange for that
      fractional share interest, and gain or loss will be recognized for federal
      income tax purposes on receipt of the cash payment, measured by the
      difference between the amount of cash received and the portion of the
      basis of the Imatron common stock allocable to the fractional share
      interest. The gain or loss will be long term capital gain or loss if the
      Imatron common stock is considered to have been held for more than one
      year at the time of the merger.

    If the Internal Revenue Service determines successfully that the merger is
not a reorganization within the meaning of Section 368(a) of the Code, Imatron
shareholders would be required to recognize gain or loss with respect to each
share of Imatron stock surrendered in the merger in an amount equal to the
difference between the tax basis in that share of stock and the fair market
value of the GE common stock received in exchange therefor. In such event, a
Imatron shareholder's aggregate tax basis in the GE common stock received in the
merger would equal its fair market value, and the shareholder's holding period
for the GE common stock would begin the day after the merger.

APPRAISAL RIGHTS

    New Jersey corporate law provides that in some mergers, shareholders who
oppose a proposed merger or do not vote in favor of the merger and who comply
with a series of statutory requirements can request a court to order a fair
valuation of the merger consideration. Under the terms of the merger and in
accordance with New Jersey corporate law, however, the Imatron shareholders are
not entitled to these rights, called appraisal or dissenters' rights.

    No appraisal or dissenters' rights are available under the merger because
shareholders will receive GE shares, which are listed on the New York Stock
Exchange, a national securities exchange.

SHAREHOLDER LITIGATION


    Since the signing of the merger agreement, two suits have been filed by
shareholders of Imatron against Imatron and its directors seeking to enjoin the
merger, and seeking monetary relief for alleged breaches of fiduciary duty by
the board of directors of Imatron. In the suit styled as "Kirby Hammond v.
Imatron, Inc., Douglas P. Boyd, Allen M. Chozen, John L. Couch, William J.
McDaniel, S. Lewis Meyer, Richard K. Myler, Terry Ross and Aldo J. Test," filed
September 26, 2001 in the Superior Court of the State of California for the
County of San Mateo, the plaintiff seeks to certify a class action suit alleging
a breach of fiduciary duty, and seeking injunctive and monetary relief. In the
suit styled as


                                       38


"Alan Fisk, Jr., v. Imatron, Inc., Douglas P. Boyd, S. Lewis Meyer, Terry Ross,
Allen M. Chozen, John L. Couch, Rear Admiral William J. McDaniel, M.D.,
Richard K. Myler and Aldo J. Test," filed October 5, 2001, in the Superior Court
of the State of California for the County of San Mateo, the plaintiff also seeks
to certify a class action suit alleging a breach of fiduciary duty, and seeking
injunctive relief. Imatron and its directors believe the suits are without merit
and not in the best interests of the shareholders of Imatron, and intend to
mount a vigorous defense against these claims.


                                       39

                              THE MERGER AGREEMENT

    THE FOLLOWING IS A SUMMARY OF SOME OF THE PROVISIONS OF THE MERGER
AGREEMENT. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER
AGREEMENT, WHICH IS INCORPORATED BY REFERENCE IN ITS ENTIRETY AND ATTACHED TO
THIS PROXY STATEMENT/PROSPECTUS AS ANNEX A. WE URGE YOU TO READ THE MERGER
AGREEMENT IN ITS ENTIRETY.

FORM OF THE MERGER

    If the holders of Imatron common stock approve and adopt the plan of merger
and all other conditions to the merger are satisfied or waived, Imatron will be
merged with a subsidiary of GE, with Imatron surviving the merger and becoming a
wholly owned subsidiary of GE. GE and Imatron anticipate that the closing of the
merger will occur as promptly as practicable after the approval of the Imatron
shareholders at the special meeting.

MERGER CONSIDERATION

    As a result of the merger, each share of Imatron common stock will
automatically be converted into the right to receive from GE a fraction of a
share of GE common stock. The exact fraction of a GE common share to be
exchanged will be equal to $1.89 divided by the average of the daily volume-
weighted sales prices per share of GE common stock on the NYSE for the ten
consecutive trading days ending on the trading day which is five calendar days
prior to the closing of the merger. Shareholders will receive shares of GE
common stock plus cash instead of fractional shares of GE common stock.


    The merger consideration generally is intended to provide shares of GE
common stock in exchange for your Imatron common stock which is valued at $1.89.
The exchange ratio is based upon the average GE share price during the ten-day
valuation period, and, therefore, a higher average GE share price would result
in fewer shares of GE common stock constituting the merger consideration, and a
lower average GE share price would result in more shares of GE common stock
constituting the merger consideration. For example, if the average GE share
price during the ten-day valuation period were equal to $38.77 per share, one
Imatron share would become 0.049 shares of GE common stock. An average GE share
price during the ten-day valuation period greater than $38.77 would result in
fewer than 0.049 shares of GE common stock constituting the merger consideration
and an average GE share price less than $38.77 would result in more than 0.049
shares of GE common stock constituting the merger consideration.


    The merger agreement provides that the ten-day valuation period will end on
the trading day which is five calendar days prior to the date of the merger. As
a result, the number of shares of GE common stock constituting the merger
consideration will be fixed five calendar days before the merger. Because the
market price of GE common stock fluctuates, the value of GE common stock that
Imatron shareholders will receive in the merger may increase or decrease during
the five-day period between the end of the valuation period and the date of the
merger. You may call, toll-free, (800) 250-7979 for information concerning the
estimated number of shares of GE common stock that will be issued in exchange
for each share of Imatron common stock as of the date you call. As part of its
ongoing stock repurchase program, GE may reacquire shares of its common stock
during the valuation period. For additional information see "Summary Selected
Financial Data--Comparative Market Price Data."

    Shares of Imatron common stock held by GE and all treasury shares will be
cancelled in the merger.

    If, between the date of the merger agreement and the merger, the outstanding
shares of GE common stock have been changed into a different number of shares or
a different class, by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
the merger agreement provides that the merger consideration will be
correspondingly adjusted to the extent appropriate to reflect such changes.

                                       40

EFFECTIVE TIME

    The merger will become effective when a certificate of merger is received by

COVENANTS AND AGREEMENTS

    CONDUCT OF BUSINESS OF IMATRON.  Imatron has agreed that, between the date
of the merger agreement and the closing of the merger, it will carry on its
business in the ordinary course and use its reasonable best efforts to maintain
its current business organizations, retain its current officers and key
employees and preserve its relationships with customers, suppliers and others
having business dealings with it. In addition, the merger agreement limits
Imatron's ability, without GE's prior written consent, to:

    - pay any dividends or otherwise make any payments to its shareholders;
      effect a stock split, combination or reclassification or authorize the
      issuance of any other securities in respect of shares of its capital
      stock; or acquire any shares of its capital stock or any rights to acquire
      any such shares;

      otherwise encumber capital stock or any related warrants or options;

    - sell, lease or otherwise dispose of any of its material assets, other than
      sales of inventory in the ordinary course of business consistent with past
      practice;

      indebtedness between Imatron and any of its wholly owned subsidiaries or
      between any wholly owned subsidiaries;

    - alter the corporate structure or ownership of Imatron or any subsidiary;

    - subject to exceptions set forth in the merger agreement, enter into or
      amend any severance plan, employment agreement or consulting agreement
      outside of the ordinary course of business;

    - subject to exceptions set forth in the merger agreement, increase the
      compensation payable to its directors, officers or employees or enter into
      or amend any employment agreement or collective bargaining agreement;

    - knowingly violate any applicable material law;

    - make any change to accounting policies or procedures;

    - take any position with respect to taxes that is inconsistent with
      positions taken in prior periods;

    - make any tax election or settle any material income tax liability;

    - commence any litigation or settle any material claims or litigation;

    - subject to exceptions set forth in the merger agreement, enter into or
      amend any material agreement or contract, purchase any real property or
      agree to make any new capital expenditure in excess of an aggregate of
      $500,000;

    - discharge liabilities and obligations outside of the ordinary course of
      business;

    - make any further loans or advances to Positron without the consent to GE,
      which consent may not be withheld unreasonably; or

    - authorize any of the foregoing.

    NO SOLICITATION.  The merger agreement prohibits Imatron, its subsidiaries,
officers, directors, employees, financial advisors or attorneys or other advisor
or representative of Imatron from soliciting,

                                       43

initiating or encouraging the submission of a takeover proposal, entering into
any agreement with respect to or approve or recommend any takeover proposal, or
providing information to (other than referring a third party to this covenant in
the agreement or providing them with a copy of this covenant) or having
discussions or negotiations with anyone other than GE for any takeover proposal,
unless:

    - done in compliance with Rule 14e-2 of the Securities Exchange Act of 1934
      with regard to a tender or exchange offer; or

    - Imatron's board reasonably determines the takeover proposal constitutes a
      superior proposal, in which case Imatron may, to the extent required by
      the fiduciary obligations of Imatron's board, as determined in good faith
      by a majority of the board after consultation with independent counsel,
      furnish non-public information and participate in discussions or
      negotiations regarding the superior proposal and enter into an agreement
      with respect to or approve or recommend to its shareholders a superior
      proposal.

    Under the merger agreement, a takeover proposal is defined as any proposal
for a merger, tender offer, or other business combination involving Imatron or
any of its subsidiaries or any proposal or offer to acquire in any manner,
directly or indirectly, an equity interest in, any voting securities of, or a
substantial portion of the assets of Imatron or any of its subsidiaries, other
than the merger with GE. Under the merger agreement, a superior proposal is
defined as a bona fide proposal made by a third party to acquire Imatron
pursuant to a tender or exchange offer, a merger, a sale of all or substantially
all its assets or otherwise on terms which a majority of the disinterested
members of the board of directors of Imatron determines at a duly constituted
meeting of the board of directors or by unanimous written consent, in its
reasonable good faith judgment, after consultation with its financial advisor,
to be more favorable to the Imatron shareholders than the merger with GE and for
which financing, to the extent required, is then committed or reasonably capable
of being obtained.

    Imatron has agreed to advise GE orally and in writing within twenty-four
hours of

    - its receipt of any takeover proposal, expression of interest or inquiry
      regarding a potential takeover proposal received by any officer or
      director of Imatron or, to the knowledge of Imatron, any financial
      advisor, attorney or other advisor or representative of Imatron;

    - the material terms of such takeover proposal, including a copy of any
      written proposal; and

    - the identity of the person making any such takeover proposal or inquiry.

    If Imatron intends to participate in discussions with or furnish any
information to another party with respect to any inquiry or takeover proposal,
Imatron will advise GE in writing of such intention not less than forty-eight
hours in advance of providing such information.

    THIRD PARTY STANDSTILL AGREEMENTS.  From the date of the merger agreement
through the closing of the merger, Imatron has agreed not to terminate, amend,
modify or waive any provision of any confidentiality or standstill agreement to
which Imatron is a party, except those involving GE, and to enforce those
agreements to the fullest extent permitted by law.

    REORGANIZATION.  From the date of the merger agreement through the closing
of the merger, all the parties to the merger have agreed not to take or fail to
take any action with actual knowledge that such action would jeopardize the
qualification of the merger as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code. Additionally, the parties have
further agreed to use all reasonable best efforts to refrain from taking any
action or failing to take any action which would cause, or would be reasonably
likely to cause, the merger to fail to qualify as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code.

                                       44

    STOCK OPTION PLANS.  The vesting of all Imatron stock options will be
accelerated immediately prior to the effective time of the merger, and will be
cancelled. Just prior to such cancellation, each outstanding Imatron stock
option that has an exercise price less than $1.89 will be converted into a right
to receive the number of shares of GE common stock (with cash in lieu of
fractional shares) determined by multiplying the number of shares of Imatron
common stock subject to such Imatron stock option immediately prior to the
merger by an amount equal to the product of (A) a fraction, the numerator of
which is $1.89 minus the sum of (i) the exercise or purchase price of the
Imatron stock option per share and (ii) all taxes required to be held in
connection with the stock option per share, and the denominator of which is
$1.89, and (B) the amount determined by dividing $1.89 by the average of the
daily volume-weighted sales prices per share of GE common stock on the NYSE for
the ten consecutive trading days ending on the trading day which is five
calendar days prior to the closing of the merger.

    Each Imatron stock option that has an exercise price equal to or greater
than $1.89 per share will terminate. However, each holder of an Imatron stock
option who will be continuing as an employee of GE after the merger will be
offered the opportunity to waive their rights in these out-of-the-money options
in exchange for options to purchase GE common stock. The GE stock options will
be granted under GE's existing stock option plan and be subject to GE's
customary terms and conditions, except that

    - the number of shares subject to the new GE stock options will be equal to
      the number of shares subject to the terminated Imatron stock options,
      multiplied by the exchange ratio;

    - the exercise price of the new GE stock options will be equal to the
      exercise price of the terminated Imatron stock options divided by the
      exchange ratio; and

    - the vesting schedule for the new GE stock options will approximate the
      vesting schedule for the terminated Imatron stock options (without giving
      effect to any acceleration in connection with the merger), except that
      future vesting will occur only in September of each subsequent calendar
      year.

    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.  The merger agreement
provides that, after the merger, GE will, as permitted by law, indemnify persons
who were Imatron's directors or officers immediately before the merger who
suffer liabilities or losses from any threatened or actual claim or proceeding
based on the merger agreement or on the fact that the person was a Imatron
director or officer. The merger agreement further allows Imatron to purchase
"tail" coverage under a director and officer liability insurance policy for the
people who were Imatron officers and directors immediately prior to the merger
for a period of not more than six years from the merger. GE also agrees that,
after the merger, it will guarantee the obligations of the surviving corporation
under the preceding two sentences. In no event, however, will either GE or the
surviving corporation be obligated to pay, in the aggregate and including any
fines, penalties or other amounts paid to third parties, any amount in excess of
$35,600,000.

    EMPLOYEE BENEFIT PLANS.  The merger agreement provides that for the first
year following the closing of the merger, while employed by Imatron, U.S.
employees of Imatron will receive base wages and salaries at rates not less
favorable to those employees than the rates of wages and salaries paid by
Imatron on the date of the merger agreement (excluding bonuses and variable
pay). For a period of one year following the closing of the merger, GE shall or
shall cause Imatron to maintain in effect U.S. employee benefit plans and
arrangements which provide benefits which have a value which is substantially
comparable, in the aggregate, to the benefits provided by Imatron's U.S. benefit
plans not taking into account the value of any plans which are equity based. For
purposes of determining eligibility to participate, vesting and accrual or
entitlement to benefits where length of service is relevant, U.S. Imatron
employees will receive service credit for service with Imatron and its
subsidiaries

                                       45

to the same extent that credit was granted under Imatron's benefit plans,
subject to offsets for previously accrued benefits and no duplication of
benefits.

    EMPLOYEE STOCK PURCHASE PLAN.  The merger agreement requires Imatron to
suspend all purchases under Imatron's 1994 Employee Stock Purchase Plan
beginning with the first payroll period following signing of the merger
agreement.

filed against Imatron and its directors, seeking injunctive relief and damages
for, among other things, breach of the directors' fiduciary duties to Imatron
shareholders. See "THE MERGER--Shareholder Litigation." If these actions are
pending at the proposed effective time for the merger and it is determined that
the existence of these actions is material, or if the plaintiffs are successful
in enjoining the merger, GE would have the right to refuse to consummate the
merger. If this condition were to continue past June 15, 2001, GE could
terminate the merger agreement without penalty, as described below in
"Termination of the Merger Agreement--TERMINATION"

TERMINATION OF THE MERGER AGREEMENT

    TERMINATION.  The merger agreement may be terminated at any time prior to
the merger, whether before or after approval by the Imatron shareholders:

    - by the mutual written consent of GE and Imatron;

    - by either GE or Imatron if: the other party has failed to comply in any
      material respect with its covenants or agreements contained in the merger
      agreement and the failure to comply has not been cured within five
      business days after receiving written notice of the failure to comply;
      there has been a breach by the other party of any representation or
      warranty which has the effect of making such representation or warranty
      not true and correct in all material respects and the breach has not been
      cured within five business days after receiving written notice of the
      breach; the merger has not closed on or prior to the close of business on
      June 15, 2002, or the date that is 75 days after the Hart-Scott-Rodino
      waiting period has expired unless the terminating party caused the delay;
      any court or other governmental entity having jurisdiction over a party to
      the merger agreement has issued an order, decree or ruling or taken any
      other action prohibiting the merger; the Imatron shareholders do not
      approve the plan of merger at the special meeting or at any adjournment or
      postponement of the special meeting; or Imatron enters into a merger,
      acquisition or other agreement with another party that qualifies as a
      superior proposal, or the board resolves to do so; except that Imatron may
      not terminate the merger agreement for this reason unless: Imatron has
      delivered to GE a written notice of Imatron's intent to enter into

                                       47

      such an agreement; forty-eight hours have elapsed following delivery to GE
      of such written notice by Imatron; and during that period, Imatron has
      fully cooperated with GE, including informing GE of the terms and
      conditions of the takeover proposal and the identity of the person making
      the takeover proposal, with the intent of enabling GE to agree to a
      modification of the terms and conditions of the merger agreement so that
      the transactions contemplated thereby may be effected; and Imatron may not
      terminate the merger agreement unless at the end of the forty-eight hour
      period the Imatron board still reasonably believes that the takeover
      proposal is a superior proposal when compared to the GE merger, taking
      into account any such modification as may be proposed by GE, and
      concurrently with such termination Imatron pays to GE the amounts
      specified under "FEES AND EXPENSES" below.

    - by GE if: the Imatron board has not recommended, or has resolved not to
      recommend, or has qualified, modified or withdrawn its recommendation of
      the merger or its declaration that the merger is advisable and fair to and
      in the best interest of Imatron and its shareholders, or has resolved to
      do so; the Imatron board has recommended to the Imatron shareholders any
      takeover proposal or has resolved to do so; or a tender offer or exchange
      offer for 20% or more of the outstanding shares of Imatron common stock is
      made by a third party that is not an affiliate of GE, and the Imatron
      board does not recommend against acceptance of such tender offer or
      exchange offer by its shareholders.

    - by either GE or Imatron if the Hart-Scott-Rodino waiting period has not
      expired or been terminated by June 15, 2002.

    EFFECT OF TERMINATION.  If the merger agreement is terminated as described
above, the agreement will be null and void, and there will be no liability for
any party or its officers and directors except as to confidentiality and fees
and expenses.

FEES AND EXPENSES

    TERMINATION FEE.  Imatron has agreed to pay GE a termination fee of up to
$11 million if the merger agreement is terminated because Imatron enters into a
merger, acquisition or other agreement related to a superior proposal, or:

    - by Imatron due to the failure of the merger to close by June 15, 2002
      after receipt by Imatron of a superior proposal;

    - due to Imatron's failure to comply in any material respect with the
      covenants of the merger agreement;

    - due to the failure by the Imatron board of directors to recommend the plan
      of merger or merger agreement, its approval of another takeover proposal,
      or its failure to recommend against a tender or exchange offer as
      described above in "--TERMINATION";

    - due to Imatron's material breach of a representation or warranty after the
      receipt of a superior proposal; or

    - due to the failure of the Imatron shareholders to approve the merger at
      the special meeting or any adjournment or postponement, after the receipt
      of a superior proposal or after the failure by the Imatron board of
      directors to recommend the merger agreement, its approval of another
      takeover proposal, or its failure to recommend against a tender or
      exchange offer as described above in "--TERMINATION"; and

                                       48

    within twelve months of the termination of the merger agreement for one of
these reasons, one of the following events occurs:

    - any person, entity or group acquires or becomes the beneficial owner of
      20% or more of the outstanding shares of Imatron common stock;

    - any group is formed which beneficially owns 20% or more of the outstanding
      shares of Imatron common stock;

    - Imatron enters into, or announces that it proposes to enter into, any
      agreement providing for a merger or other business combination involving
      Imatron or the acquisition of a substantial interest in, or a substantial
      portion of the assets, business or operations of, Imatron, other than the
      transaction contemplated in the merger agreement;

    - any person, entity or group is granted any option or right, conditional or
      otherwise, to acquire or otherwise become the beneficial owner of shares
      of Imatron common stock which, together with all shares of Imatron common
      stock beneficially owned by that person, entity or group, results or would
      result in such person being the beneficial owner of 20% or more of the
      outstanding shares of Imatron common stock; or

    - there is a public announcement with respect to a plan or intention by
      Imatron to effect any of the foregoing transactions.

    The $11,000,000 termination fee will be reduced by the net amount realized
or realizable by GE under the stock option agreement. In addition, the total of
the termination fee and the net amount actually realized by GE under the stock
option agreement (after netting out the exercise price) will not exceed
$11,000,000.

    EXPENSES.  Whether the merger is completed, all costs and expenses incurred
in connection with the merger agreement, including the costs of counsel,
financial advisors and accountants, will be paid by the party incurring those
costs and expenses. Printing expenses and all filing fees, including filing fees
under the Securities Act of 1933, the Securities Exchange Act of 1934 and the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, will be divided equally
between GE and Imatron. However, Imatron has agreed to pay GE's costs and
expenses up to a maximum of $1.5 million if the merger agreement is terminated:

    - by Imatron due to the failure of the merger to close by June 15, 2002,
      after receipt by Imatron of a superior proposal;

    - due to Imatron's failure to comply in any material respect with the
      covenants of the merger agreement;

    - due to Imatron's material breach of a representation or warranty;

    - due to the failure by the Imatron board of directors to recommend the
      merger agreement and plan of merger, its approval of another takeover
      proposal, or its failure to recommend against a tender or exchange offer
      as described above in "--TERMINATION";

    - due to the failure of the Imatron shareholders to approve the merger at
      the special meeting after a superior proposal is made by a third party or
      after the failure by the Imatron board of directors to recommend the
      merger agreement and plan of merger, its approval of another takeover
      proposal, or its failure to recommend against a tender or exchange offer
      as described above in "--TERMINATION"; or

    - due to Imatron's agreement to a merger, acquisition or other agreement to
      effect a superior proposal.

                                       49

    GE has agreed to pay Imatron's costs and expenses up to a maximum of
$1.5 million if Imatron terminates the merger agreement due to:

    - GE's failure to comply in any material respect with the covenants of the
      merger agreement; or

    - GE's material breach of a representation or warranty.

AMENDMENT; WAIVER

    AMENDMENT.  The merger agreement may be changed by GE and Imatron at any
time prior to the approval of the plan of merger by the Imatron shareholders.
Any change made after the approval of the plan of merger by the Imatron
shareholders by law must be approved by the Imatron shareholders. The merger
agreement may only be amended in a writing signed by GE, Imatron and Ruby Merger
Corp.

    WAIVER.  At any time prior to the merger, GE and Imatron may agree to:

    - extend the time for the performance of any obligation or other act of the
      other party;

    - waive any inaccuracy in the representations and warranties contained in
      the merger agreement or in any document delivered under the terms of the
      merger agreement; and

    - waive compliance with any agreement or condition contained in the merger
      agreement which may be legally waived.

    Any extension or waiver will be valid only if made in writing and signed on
behalf of the waiving party.

                           THE STOCK OPTION AGREEMENT

    THE FOLLOWING IS A SUMMARY OF SOME OF THE PROVISIONS OF THE STOCK OPTION
AGREEMENT. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE STOCK
OPTION AGREEMENT, WHICH IS INCORPORATED BY REFERENCE IN ITS ENTIRETY AND
ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX C. WE URGE YOU TO READ THE
STOCK OPTION AGREEMENT IN ITS ENTIRETY.


    Concurrently with the execution of the merger agreement, GE and Imatron
entered into the stock option agreement pursuant to which Imatron granted to GE
an option to purchase a number of shares that, immediately prior to issuance,
would represent 19.9% of the issued and outstanding shares of Imatron common
stock. The option has an exercise price of $1.89 per share, payable in cash.
Based on the number of shares of Imatron common stock outstanding on
October 29, 2001, the option would be exercisable for 20,960,973 shares of newly
issued shares of Imatron common stock.


EXERCISABILITY

    The option is exercisable only if one or more of the following events
occurs:

    - any person, entity or group acquires or becomes the beneficial owner of
      20% or more of the outstanding shares of Imatron common stock;

    - any group is formed which beneficially owns 20% or more of the outstanding
      shares of Imatron common stock;

    - any person, entity or group commences a tender or exchange offer for 20%
      or more of the outstanding Imatron common stock or publicly proposes any
      merger, consolidation or acquisition of all or substantially all the
      assets of Imatron or other business combination involving Imatron;

    - Imatron enters into, or announces that it proposes to enter into, any
      agreement providing for a merger or other business combination involving
      Imatron or any significant subsidiary of Imatron or the acquisition of a
      substantial interest in, or a substantial portion of the assets, business
      or operations of, Imatron or a significant subsidiary of Imatron, other
      than the transactions contemplated in the merger agreement;

    - any person, entity or group is granted any option or right, conditional or
      otherwise, to acquire or otherwise become the beneficial owner of shares
      of Imatron common stock which, together with all shares of Imatron common
      stock beneficially owned by that person, entity or group, results or would
      result in such person, entity or group being the beneficial owner of 20%
      or more of the outstanding shares of Imatron common stock; or

    - there is a public announcement with respect to a plan or intention by
      Imatron to effect any of the foregoing transactions.

    Additionally, GE may not exercise the option if:

    - GE or Ruby Merger Corp. has breached any of its material obligations under
      the merger agreement;

    - an injunction or other order issued by any federal or state court which
      invalidates the grant or prohibits the exercise of the option is in
      effect;

    - the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
      has not expired or been terminated; or

    - the purchase of the shares will violate Rule 10b-13 promulgated under the
      Securities Exchange Act of 1934.

                                       51

PUT RIGHT

    At any time before the termination of the option, under the circumstances
described below, GE has the right to require Imatron to purchase the option from
GE at a cash purchase price equal to the product determined by multiplying
(A) the number of shares as to which the option has not yet been exercised by
(B) the per share cash value of the option as determined in accordance with the
stock option agreement.

    GE can require Imatron to purchase the option if any of the following events
occur:

    - any person, entity or group other than GE acquires or becomes the
      beneficial owner of 50% or more of the outstanding shares of Imatron
      common stock; or

    - Imatron consummates a merger or other business combination with a third
      party.

REPURCHASE RIGHT

    For 90 days after the termination of the option, Imatron has the right to
repurchase from GE all of the optioned shares acquired by GE, and with respect
to which GE then has beneficial ownership, at a price per share equal to the
greater of:

    - the average of the daily volume-weighted quoted on Nasdaq National Market
      of Imatron common stock during the five trading days immediately before
      Imatron provides written notice of its intent to repurchase; and

    - $1.89, plus interest at a rate per annum equal to the costs of funds to GE
      at the time of the repurchase.

REGISTRATION RIGHTS

    If GE exercises the option, it will have the following registration rights
with respect to the option shares:

    - subject to certain restrictions set forth in the stock option agreement,
      piggy-back registration rights which allow GE to participate in any
      registration of Imatron shares initiated by Imatron so long as GE is
      requesting participation with respect to at least 20% of the option
      shares; and

    - subject to certain restrictions set forth in the stock option agreement,
      demand registration rights which allow GE to request that Imatron register
      GE's shares so long as GE is demanding registration of at least 20% of the
      option shares.

TERMINATION

    The stock option agreement and the option terminate upon the earlier of:

    - the closing of the merger; and

    - the termination of the merger agreement in accordance with its terms.

However, the option will not terminate until 12 months after a termination under
certain circumstances related to a third party acquisition attempt, and, in such
case, Imatron's repurchase right will not terminate until 90 days after the
termination of GE's option.

MAXIMUM AMOUNT REALIZABLE BY GE

    If GE exercises the option and then sells the stock received by GE under the
option or if GE exercises its put right, GE may be required to give some of the
money it makes on that sale to Imatron. If the sum of the gross proceeds from
the sale of the option shares or the exercise of the put

                                       52

right and the amount of the termination fee received by GE exceeds the sum of
$11,000,000, GE must pay to Imatron the amount in excess of $11,000,000 less the
exercise price and the cost of discounts and commissions.

EFFECT OF THE STOCK OPTION AGREEMENT

    The option might increase the likelihood of closing the merger by
discouraging competing offers to acquire Imatron. Imatron entered into the stock
option agreement to induce GE to enter into the merger agreement. The stock
option agreement may discourage persons who may be interested in acquiring all
of or a significant interest in Imatron from considering or proposing an
acquisition, even if they were prepared to offer to pay a higher price than
$1.89 per share.

    THE FOLLOWING IS A SUMMARY OF SOME OF THE PROVISIONS OF THE SHAREHOLDER
AGREEMENTS. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
SHAREHOLDER AGREEMENTS, WHICH ARE INCORPORATED BY REFERENCE IN ITS ENTIRETY AND
ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEXES D AND E. WE URGE YOU TO

    Concurrently with the execution of the merger agreement, in order to induce
GE to enter into the merger agreement, certain shareholders entered into
shareholder agreements with GE.

COVENANTS

    The shareholder agreements provide, among other things, that the
shareholders subject to the agreements:

    - will attend the special meeting in person or by proxy, and vote the shares
      subject to the agreements in favor of the approval of the merger and
      adoption of the merger agreement and of the other transactions
      contemplated by the merger agreement;

    - will vote the shares subject to the agreements against: any merger
      agreement or merger other than the GE merger or other business combination
      or any other takeover proposal, or any amendment of the Imatron
      certificate of incorporation or the bylaws or other proposal or
      transaction which would in any manner impede, frustrate, prevent or
      nullify the merger, the merger agreement or any of the other transactions
      contemplated by the merger agreement;

    - will not sell, transfer, pledge, assign or otherwise dispose of or enter
      into any arrangement to transfer the shares subject to the agreements, or
      enter into any voting arrangement, whether by proxy, voting agreement or
      otherwise, in relation to the shares subject to the agreements;

                                       54

    - will not directly or through a representative solicit, initiate or
      encourage a third party to make a takeover proposal to Imatron, or take
      any action to facilitate any third party takeover proposal;

    - will use their reasonable best efforts to take all actions and to do all
      things necessary, proper or advisable to support and to close the merger
      in accordance with the terms of the merger agreement;

    - will notify GE in writing of the nature and amount of any acquisition by
      them of any voting securities of Imatron acquired by them after the date
      of the shareholder agreements;

    - will not knowingly take or fail to take any action which would cause any
      of the representations and warranties set forth in the tax certificate
      attached to the shareholder agreements to be untrue or incorrect; and

    - will revoke any and all prior proxies or powers of attorney in respect to
      any shares subject to the agreements and will irrevocably appoint GE and
      Ruby Merger Corp., at any time during the terms of the shareholder
      agreements, as its true and lawful attorney and proxy, for and in its
      name, place and stead, for any and all purposes, including without
      limitation, to demand that the Secretary of Imatron call a special meeting
      of the shareholders of Imatron for the purpose of considering any matter
      related to the merger agreement or voting against another takeover
      proposal, to vote each of the shares subject to the agreements as its
      proxy at every meeting of the shareholders of Imatron.

The agreements provide, however, that nothing in the agreement will be construed
to limit such shareholder's ability to discharge such shareholder's fiduciary
duties as a director of Imatron, including the right to vote for or support a
superior offer or proposal.

OPTION GRANT

    The shareholders granted to GE options to purchase the shares subject to
each shareholder agreement. Each option has an exercise price of $1.89 per
share, payable in cash. The options are exercisable only if one or more of the
following events occurs:

    - any person, entity or group acquires or becomes the beneficial owner of
      20% or more of the outstanding shares of Imatron common stock;

    - any group is formed which beneficially owns 20% or more of the outstanding
      shares of Imatron common stock;

    - any person, entity or group commences a tender or exchange offer for 20%
      or more of the outstanding Imatron common stock or publicly proposes any
      merger, consolidation or acquisition of all or substantially all the
      assets of Imatron, or similar business combination involving Imatron;

    - Imatron enters into, or announces that it proposes to enter into, any
      agreement providing for a merger or other business combination involving
      Imatron or a significant subsidiary of Imatron or the acquisition of a
      substantial interest in, or a substantial portion of the assets, business
      or operations of, Imatron or a significant subsidiary of Imatron, other
      than the transaction contemplated in the merger agreement;

    - any person, entity or group is granted any option or right, conditional or
      otherwise, to acquire or otherwise become the beneficial owner of shares
      of Imatron common stock which, together with all shares of Imatron common
      stock beneficially owned by that person, entity or group, results or would
      result in such person being the beneficial owner of 20% or more of the
      outstanding shares of Imatron common stock; or

                                       55

    - there is a public announcement with respect to a plan or intention by
      Imatron to effect any of the foregoing transactions.

    Additionally, GE may not exercise the option if:

    - GE or Ruby Merger Corp. has breached any of its material obligations under
      the merger agreement;

    - an injunction or other order issued by any federal or state court which
      invalidates the grant or prohibits the exercise of the option is in
      effect;

    - the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
      has not expired or been terminated; or

    - the purchase of the shares will violate Rule 10b-13 promulgated under the
      Exchange Act.

Shares subject to options or warrants that are held by the subject shareholders
will become shares subject to the shareholder agreements upon issuance. However,
GE does not have the power under the shareholder agreements to force the
shareholders to exercise such rights.

TERMINATION

    The shareholder agreements terminate on the earlier of six months (or sixty
days in the case of Mr. Ross) after the termination of the merger agreement, and
the effective time of the merger. However, if the merger agreement is terminated
either by the mutual agreement of GE and Imatron or solely by Imatron because of
a breach by GE of a covenant in the merger agreement; a material breach of a
representation or warranty; the failure of the merger to close by June 15, 2002,
or 75 days after the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act, unless it follows receipt of a superior proposal; or the
issuance of an order by any governmental entity permanently prohibiting the
transactions contemplated by the merger agreement, then the shareholder
agreements terminate immediately upon the termination of the merger agreement.

                               REGULATORY MATTERS

    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules
of the Federal Trade Commission, the merger may not be consummated until
notifications have been given and certain information has been furnished to the
FTC and the Antitrust Division of the United States Department of Justice and
specified waiting period requirements have been satisfied. GE and Imatron each
filed notification and report forms with the FTC and the Department of Justice
effective October 19, 2001.

    GE and Imatron have also made, or expect to make, filings with regulatory
authorities pursuant to antitrust laws in countries where such filing is
required. It is currently anticipated that necessary clearances under these laws
will be obtained prior to the special meeting.

    GE and Imatron are not aware of any material governmental or regulatory
approvals required to be obtained in order to consummate the merger, other than
compliance with the Hart-Scott-Rodino Antitrust Improvements Act and foreign
antitrust laws, mentioned above and applicable federal and state securities and
corporate laws.

                                       56

                   SUBMISSION OF FUTURE SHAREHOLDER PROPOSALS

    Due to the contemplated closing of the merger, Imatron does not currently
expect to hold a 2002 annual meeting of shareholders because, following the
merger, Imatron will not be a publicly-traded company. If the merger is not
consummated and the meeting is held, to be eligible for inclusion in Imatron's
proxy statement and form of proxy relating to the meeting, shareholders'
proposals must be delivered to the Secretary of Imatron at the principal
executive offices not less than 90 nor more than 120 calendar days in advance of
the anniversary date of the preceding year's annual meeting of shareholders.

        COMPARISON OF RIGHTS OF IMATRON SHAREHOLDERS AND GE STOCKHOLDERS

    THE STATEMENTS SET FORTH UNDER THIS HEADING WITH RESPECT TO THE NEW JERSEY
BUSINESS CORPORATION ACT ("NJBCA"), IMATRON'S CERTIFICATE OF INCORPORATION,
IMATRON'S BYLAWS, THE NEW YORK BUSINESS CORPORATION LAW ("NYBCL"), GE'S
CERTIFICATE OF INCORPORATION, AND GE'S BYLAWS, AS AMENDED, ARE BRIEF SUMMARIES
AND DO NOT PURPORT TO BE COMPLETE. THE STATEMENTS IN THIS SECTION ARE QUALIFIED
IN THEIR ENTIRETY BY REFERENCE TO AND ARE SUBJECT TO THE DETAILED PROVISIONS OF
THE NYBCL, NJBCA, IMATRON'S CERTIFICATE OF INCORPORATION, IMATRON'S BYLAWS, GE'S
CERTIFICATE OF INCORPORATION AND GE'S BYLAWS.

    After the merger, shareholders of Imatron will become stockholders of GE.
Since GE is a New York corporation, the rights of the stockholders of GE are
governed by the applicable laws of the State of New York, including the NYBCL,
and by the GE charter and the GE bylaws. Since Imatron is a New Jersey
corporation, the rights of the shareholders of Imatron are governed by the
applicable laws of the State of New Jersey, including the NJBCA, and by the
Imatron certificate of incorporation and the Imatron bylaws.

    While there are similarities between the NYBCL and the NJBCA, as well as
between the charters and bylaws of GE and Imatron, a number of differences
exist. The following is a summary of some of these differences between the
current rights of GE stockholders and Imatron shareholders under the NYBCL and
the NJBCA, and under the charters and bylaws of GE and Imatron.

AUTHORIZED CAPITAL STOCK

    GE.  The authorized capital stock of GE currently consists of 13,250,000,000
shares of capital stock, consisting of (i) 13,200,000,000 shares of GE common
stock, par value $0.06 per share, and (ii) 50,000,000 shares of preferred stock,
par value $1.00 per share.

    IMATRON.  The authorized capital stock of Imatron currently consists of
160,000,000 shares of capital stock, consisting of (i) 150,000,000 shares of
common stock, no par value per share and (ii) 10,000,000 shares of preferred
stock.

VOTING RIGHTS

    Under both the NYBCL and NJBCA, all matters submitted to stockholders for a
vote at a meeting require, for approval, the presence of a quorum, consisting of
holders of shares entitled to cast a majority of the votes at the meeting, and,
except for the election of directors, the affirmative vote of the majority of
votes cast, unless otherwise provided by statute, a corporation's certificate of
incorporation or, under the NYBCL, its bylaws. Directors are elected by a
plurality of the votes cast, unless otherwise provided in the certificate of
incorporation.

    Neither GE common stock nor Imatron common stock is divided into classes.
Each share of GE common stock and each share of Imatron common stock entitles
the holder to one vote on each matter upon which shareholders have the right to
vote.

                                       57

    Under the NYBCL, a plan of merger, consolidation, dissolution or disposition
of all or substantially all of the corporation's assets is required to be
approved (a) for corporations in existence on February 22, 1998 whose
certificates of incorporation expressly so provide (or for corporations formed
after that date), by a majority of the votes of all outstanding shares entitled
to vote thereon, and (b) in the case of all other corporations, including GE, by
two-thirds of the votes of all outstanding shares entitled to vote thereon.

    Under the NJBCA, a plan of merger, consolidation, dissolution or disposition
of all or substantially all of the corporation's assets is required to be
approved (a) for corporations in existence before January 1, 1969, unless
otherwise provided by statute or the corporation's certificate of incorporation,
by two-thirds of the votes cast by holders of shares entitled to vote thereon,
and (b) in the case of all other corporations, including Imatron, by a majority
of the votes cast by holders of shares entitled to vote thereon. However, no
authorizing shareholder vote is required of a corporation surviving a merger
unless required by the corporation's certificate of incorporation if:

    - the plan of merger does not make an amendment of the certificate of
      incorporation of the surviving corporation which is required by the NJBCA
      to be approved by the shareholders;

    - each shareholder of the surviving corporation whose shares were
      outstanding immediately before the effective date of the merger will hold
      the same number of shares, with identical designations, preferences,
      limitations, and rights immediately after;

    - the number of voting shares outstanding immediately after the merger, plus
      the voting shares issuable on conversion of other securities or on
      exercise of rights and warrants issued pursuant to the merger will not
      exceed by more than 40% the total number of voting shares of the surviving
      corporation outstanding immediately prior to the merger, and

    - the number of participating shares outstanding immediately after the
      merger, plus the number of participating shares issuable on conversion of
      other securities or on exercise of rights and warrants issued pursuant to
      the merger, will not exceed by more than 40% the number of participating
      shares of the surviving corporation outstanding immediately prior to the
      merger.

    Under the NYBCL, amendments to a certificate of incorporation generally must
be approved by the board of directors and a majority of all outstanding shares
entitled to vote thereon at a meeting of stockholders. The NYBCL requires that
any amendment to the certificate of incorporation of a provision specifying a
higher vote requirement than that required by the NYBCL must be approved in
compliance with such higher vote requirement.

    The GE charter may be amended if the amendment is approved by a majority
vote of the board of directors of GE and the affirmative vote of at least a
majority of outstanding shares of GE common stock.

    Under the NYBCL, except as otherwise provided in the certificate of
incorporation, bylaws may be amended, repealed or adopted by a majority of the
votes cast by the shares entitled to vote in the election of any directors. When
so provided in the certificate of incorporation or a bylaw adopted by the
stockholders, bylaws also may be amended, repealed or adopted by the board of
directors by such vote as may be specified in the bylaws, which vote may be
greater than the vote otherwise prescribed by the NYBCL, but any bylaw adopted
by the board of directors may be amended or repealed by the stockholders
entitled to vote thereon as provided by the NYBCL.

    The GE charter confers upon the GE board the power to amend or repeal the GE
bylaws, except that the GE board does not have the authority to amend or repeal
any bylaw which is adopted by the GE stockholders after April 20, 1948, unless
such authority is granted to the GE board by the specific provisions of a bylaw
adopted by the GE stockholders. The GE bylaws provide that the GE bylaws also
may be altered, amended or repealed, at any time, in the manner provided in the
GE charter.

                                       58

    Under the NJBCA, a proposed amendment to a corporation's certificate of
incorporation requires approval of the board of directors and an affirmative
vote of a majority of the votes cast by the holders of shares entitled to vote
thereon; provided that in the case of a corporation organized prior to
January 1, 1969, the proposed amendment requires board approval and the
affirmative vote of two-thirds of the votes cast by the holders of shares
entitled to vote thereon, unless the corporation has adopted the majority voting
requirement.

    The Imatron certificate of incorporation may be amended in any manner
permitted under New Jersey law. Imatron was incorporated after January 1, 1969.

    Under the NJBCA, the board of directors of a corporation has the power to
make, alter and repeal bylaws unless such power is reserved to the shareholders
in the certificate of incorporation, but bylaws made by the board of directors
may be altered or repealed or new bylaws may be adopted by the shareholders. In
addition, the shareholders may prescribe in the bylaws that any bylaws made by
shareholders shall not be altered or repealed by the board of directors.

    Under the Imatron certificate of incorporation, the Imatron bylaws may be
altered, amended or repealed or new bylaws may be adopted by the Imatron board
or by the affirmative vote of a majority of the outstanding shares at any annual
or special meeting of the shareholders, if notice of such alteration, amendment,
repeal or adoption is contained in the notice of such meeting or waiver of
notice. Bylaws adopted by the Imatron board may be amended or repealed by the
shareholders of Imatron. The Imatron bylaws contain provisions that are
consistent with the foregoing, and also provide that any amendment or repeal of
a bylaw concerning indemnification of officers and directors may only be
prospective.

SPECIAL MEETINGS OF STOCKHOLDERS; CONSENT TO ACTIONS OF STOCKHOLDERS IN LIEU OF
  MEETING

    SPECIAL MEETINGS.  Under the NYBCL, a special meeting of stockholders may be
called by the board of directors or by any person authorized to do so in the
certificate of incorporation or bylaws.

    The GE bylaws provide that special meetings of stockholders may be called by
the GE board, or by the written request of stockholders holding 40% of the
outstanding stock of GE.

    Under the NJBCA, a special meeting of shareholders may be called by the
president or the board of directors, by such other officers, directors or
shareholders as may be provided in the bylaws, or by the Superior Court of New
Jersey, for good cause, upon the application of holders of at least 10% of all
shares entitled to vote at a meeting.

    The Imatron bylaws provide that special meetings of the shareholders of
Imatron may be called at any time by the chairman of the board, the president,
the board of directors pursuant to a resolution adopted by a majority of the
total number of authorized directors, or at the written request of holders of
shares entitled to cast not less than a majority of the votes at the meeting.
Shareholders are entitled to not less than 10 and no more than 60 days notice of
any special meeting.

    CONSENT OF STOCKHOLDERS IN LIEU OF MEETING.  The NYBCL provides that
stockholder action may be taken without a meeting upon the written consent of
the holders of all the outstanding shares entitled to vote, and also allows, if
the certificate of incorporation so provides, stockholder action without a
meeting upon the written consent of holders of outstanding shares having not
less than the minimum number of votes that would be necessary to authorize such
action at a meeting at which all shares entitled to vote thereon were present
and voted. Neither the GE charter nor the GE bylaws contains any provision with
respect to actions by stockholders by written consent.

    Similarly, the NJBCA allows any action required or permitted to be taken at
a meeting of shareholders by statute or a corporation's certificate of
incorporation or bylaws to be taken without a meeting if all the shareholders
entitled to vote thereon consent thereto in writing, except that in the

                                       59

case of an action to be taken under Chapter 10 of the NJBCA (business
combinations), such action may be taken without a meeting only if all
shareholders consent thereto in writing, or if all shareholders entitled to vote
thereon consent thereto in writing and the corporation provides advance
notification (in accordance with the NJBCA) to all other shareholders.

    The NJBCA also allows, except as otherwise provided in a corporation's
certificate of incorporation, any action required or permitted to be taken by
shareholders at a meeting of shareholders, other than the annual election of
directors, to be taken without a meeting, without prior notice and without a
vote, upon a written consent of holders of not less than the minimum number of
votes necessary to authorize such action at a meeting at which all shares
entitled to vote thereon were present and voting, subject, however, to
compliance with statutorily prescribed notice and other requirements and, where
required by the NJBCA, dissenters' rights.

    The Imatron bylaws provide that any action required by statute to be taken
at any meeting of the shareholders, or any action which may be taken at any
meeting of shareholders, may be taken without a meeting, without prior notice
and without a vote, if a consent in writing setting forth the action so taken is
signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize such action at a meeting at
which all shares entitled to vote thereon were present and voted.

BUSINESS COMBINATIONS

    The NYBCL generally prohibits a domestic corporation from engaging in a
business combination with an "interested stockholder" for a period of five years
from the date the stockholder acquired the stock in such domestic corporation,
unless certain conditions are met. An interested stockholder is one who is the
beneficial owner of 20% or more of the corporation's stock or an affiliate or
associate of the corporation who has within the previous five years,
beneficially owned 20% or more of the corporation's then outstanding stock.

    The domestic corporation may engage in a business combination with the
interested stockholder within the five-year period if the interested
stockholder's stock purchase made on his stock acquisition date (as defined
below) was approved by the corporation's board of directors prior to the date
the stockholder became an interested stockholder (the "stock acquisition date").
The business combination is also permitted if any of the following criteria are
met:

    - the business combination was approved by the board of directors prior to
      the interested stockholder's stock acquisition date or where the purchase
      of stock by the interested stockholder on the stockholder's stock
      acquisition date had been approved by the board of directors prior to the
      stockholder's stock acquisition date;

    - the combination was approved by a majority of the outstanding voting stock
      not beneficially owned by the interested stockholder or any affiliate or
      associate of the interested stockholder at a meeting called no earlier
      than five years after the interested stockholder's stock acquisition date;
      or

    - the consideration to be received by stockholders meets certain
      requirements of the NYBCL with respect to form and amount.

    The NJBCA prohibits a corporation from engaging in a business combination
with an "interested stockholder" for a period of five years after the interested
stockholder's stock acquisition date, unless the board of directors approved the
business combination prior to the interested stockholder's stock acquisition
date. An interested stockholder is one who is the beneficial owner of 10% or
more of the corporation's stock or an affiliate or associate of the corporation
who has within the previous five years, beneficially owned 10% or more of the
corporation's then outstanding stock. After five years from the

                                       60

interested stockholder's stock acquisition date, the NJBCA continues to prohibit
a business combination with an interested stockholder unless:

    - the board of directors approved the business combination prior to the
      interested stockholder's stock acquisition date,

    - the business combination is approved by two-thirds of the outstanding
      voting stock not owned by the interested stockholder, or

    - the consideration to be received by stockholders meets certain
      requirements of the NJBCA with respect to form and amount.

BUSINESS CONDUCTED AT STOCKHOLDERS' MEETINGS

    Under NYBCL, stockholders must be given notice of the time and place of
every stockholder meeting and, in the case of a special meeting, the purpose or
purposes of the meeting. The business permitted to be conducted at any special
meeting of stockholders is limited to business related to the purpose or
purposes stated in the notice of meeting of stockholders.

    Under NJBCA, shareholders must be given written notice of the time, place
and purpose or purposes of every shareholder meeting, except as otherwise
provided in the NJBCA.

DIVIDENDS

    Under the NYBCL, a corporation may pay dividends out of surplus; however, no
dividends may be paid if the corporation is insolvent, if the dividend payment
would render the corporation insolvent or if such payment would be contrary to
any restrictions contained in the certificate of incorporation. Under the NJBCA,
subject to any restrictions in its certificate of incorporation, a corporation
may pay dividends unless, after the distribution of dividends, either of the
following would occur:

    - the corporation would not be able to pay its debts as they become due in
      the usual course of business, or

    - the corporation's total assets would be less than its total liabilities.

DISSENTERS' APPRAISAL RIGHTS

    The NYBCL provides that, upon compliance with the applicable statutory
requirements and procedures, a dissenting stockholder has the right to receive
payment of the fair value of such stockholder's shares if such stockholder
objects to:

    - certain mergers or consolidations to which the corporation is a party (but
      not if the corporation's shares are listed on a national securities
      exchange or quoted on NASDAQ-NMS);

    - dispositions of all or substantially all of the corporation's assets
      requiring stockholder approval other than a transaction wholly for cash
      where the stockholder's approval thereof is conditioned upon the
      dissolution of the corporation and the distribution of substantially all
      of its net assets to stockholders within one year after the date of such
      transaction;

    - specified share exchanges; or

    - amendments to the certificate of incorporation which adversely affect the
      rights of such stockholder in specified respects.

    The NJBCA similarly provides that a shareholder of a corporation is
generally entitled to receive payment of the fair value of such shareholder's
stock if such shareholder dissents from:

    - a proposed merger or consolidation,

                                       61

    - stock exchange, or

    - sale or exchange of all or substantially all of the property and assets of
      the corporation.

    However, unless otherwise provided for in the corporation's certificate of
incorporation, dissenters' rights are not available to holders of shares that
are registered on a national securities exchange or quoted on a national
securities exchange. Currently, Imatron common stock is quoted on NASDAQ and its
shares are held by more than 1,000 holders.

WARRANTS OR OPTIONS

    The NYBCL requires the approval of the holders of a majority of the votes
cast at a meeting of stockholders for the corporation's issuance of any rights
or options to directors, officers or other employees or for a plan to issue such
rights or options.

    Under the NJBCA, any plan involving the issuance of shares (including
options) to directors, officers or other employees of a corporation must be
adopted initially by the board of directors or a committee of the board.

NUMBER, TERM AND ELECTION OF DIRECTORS

    Under the NYBCL, the board of directors of a corporation must consist of one
or more members. The number of directors may be fixed by the bylaws or by action
of the stockholders or of the board of directors under the specific provisions
of a bylaw adopted by the stockholders. The number of directors may be increased
or decreased by amendment of the bylaws or by action of the stockholders or of
the board of directors under the specific provisions of a bylaw adopted by the
stockholders; provided that, if the board of directors is authorized by the
bylaws to change the number of directors, whether by amending the bylaws or by
taking action under the specific provisions of a bylaw adopted by the
stockholders, such amendment or action will require the vote of a majority of
the entire board of directors. Except where the certificate of incorporation or
stockholder adopted bylaw provides for a classified board, directors are elected
at each annual meeting, to hold office until the next annual meeting.

    Under the NJBCA, the board of directors of a corporation also must consist
of one or more members. Subject to any provision contained in a corporation's
certificate of incorporation, a corporation's by-laws must specify either the
number of directors, or that the number of directors shall not be less than a
stated minimum or more than a stated maximum, with the actual number to be
determined (except for the number constituting the first board) in accordance
with the by-laws. Except where the certificate of incorporation provides for
more than one class of directors, directors are elected at each annual meeting,
to hold office until the next annual meeting

    The GE charter provides that the GE board may not consist of less than 10
directors, with the exact number to be determined pursuant to the procedures set
forth in the GE bylaws. The GE bylaws provide that the exact number of directors
will be determined by a vote of the majority of the entire GE board, except that
the number of directors for any year will be fixed by the stockholders of GE at
any annual statutory meeting of the stockholders by a majority vote of the
outstanding shares entitled to vote thereon. The number of directors of GE is
currently fixed at fifteen. The GE bylaws provide that directors shall be
elected each year at the annual statutory meeting of stockholders. Directors of
GE hold office until the next statutory meeting of the stockholders and until
their successors are duly elected and have qualified. Any vacancy occurring in
the GE board may be filled for the unexpired term by the GE board. Neither the
GE charter nor the GE bylaws permits cumulative voting for the election of
directors

    The Imatron certificate of incorporation and bylaws provide that the board
of directors must consist of at least three and not more than twelve members.
Directors of Imatron hold office until the

                                       62

next annual meeting and until their successors are elected and qualified. Any
vacancy may be filled, until the next succeeding annual meeting of shareholders,
by the Imatron board with the affirmative vote of the majority of the directors
then in office, even if less than a quorum. Neither the Imatron certificate of
incorporation no the Imatron bylaws permits cumulative voting for the election
of directors.

CLASSIFICATION OF THE BOARD OF DIRECTORS

    Under the NYBCL, a corporation's certificate of incorporation or a
stockholder adopted bylaw may provide that the directors be divided into either
two, three or four classes. All classes must be as nearly equal in number as
possible. Under the NJBCA, a corporation's board of directors may be divided
into classes with staggered terms of office if the corporation's certificate of
incorporation so provides. No class of directors can hold office for a term of
less than one or more than 5 years and the term of at least one class must
expire each year.

    The GE charter does not contain a classified board provision. The Imatron
certificate of incorporation provides that the board of directors shall be
divided into three classes of not less than two directors with staggered
three-year terms of office.

REMOVAL OF DIRECTORS

    The NYBCL provides that any or all of the directors of a corporation may be
removed for cause and, if the certificate of incorporation or bylaws of the
corporation provide, without cause, by vote of the stockholders. A director may
also be removed for cause by the board of directors if the certificate of
incorporation or a stockholder-adopted bylaw so provides.

    Under the NJBCA, a director may generally be removed by the shareholders,
with or, unless otherwise provided in the certificate of incorporation, without
cause by the affirmative vote of a majority of the votes case by shareholders
entitled to vote for the election of directors (subject to any greater voting
requirement provided in the certificate of incorporation). A director may also
be removed for cause by the board of directors if the certificate of
incorporation or a shareholder-adopted bylaw so provides.

    Neither the GE charter nor the GE bylaws provides for removal of GE
directors. Consequently, GE directors may be removed only for cause by vote of
the stockholders of GE.

    The Imatron bylaws provide that directors of Imatron may be removed with or
without cause upon the vote a majority of the votes cast by holders of shares
entitled to vote at an election of directors.

TRANSACTIONS WITH INTERESTED DIRECTORS

    Generally, under the NYBCL and NJBCA, a contract or transaction between a
corporation and one or more of its directors, or between a corporation and any
other entity in which one or more of its directors are directors or officers, or
have a financial interest, is not void or voidable solely because of such
relationship or interest, if any of the following is true:

    - the material facts of the contract or transaction and the director's
      interest are disclosed or known to the board of directors or a committee
      of the board of directors and the board or committee in good faith
      authorizes the contract or transaction, under the NJBCA, by unanimous
      written consent (as long as one director is disinterested) or by the
      affirmative vote of a majority of the disinterested directors (even though
      less than a quorum), and under the NYBCL, by a vote sufficient for such
      purpose without counting the vote of the interested director or, if the
      votes of the disinterested directors are insufficient to constitute an act
      of the board, by unanimous vote of the disinterested directors;

                                       63

    - the material facts of the transaction and the director's interest are
      disclosed or known to shareholders entitled to vote thereon, and such
      contract or transaction is approved in good faith by a vote of such
      shareholders; or

    - under the NJBCA, the contract or transaction is fair to the corporation as
      of the time it was approved by the board, a committee or the shareholders.

INDEMNIFICATION; LIMITATION OF LIABILITY

    Both the NYBCL and the NJBCA allow a corporation to indemnify a director or
officer for certain expenses, liabilities and other amounts incurred by such
person in connection with legal proceedings.

    The NYBCL requires that, prior to making any indemnification, a
determination must be made that the indemnified person has met the applicable
statutory standard of conduct. Unless otherwise ordered by a court, that
determination is made by (i) a quorum of disinterested directors, (ii) the
board, acting upon the written opinion of independent legal counsel if so
directed by a quorum of disinterested directors or if a quorum of disinterested
directors is not obtainable, or (iii) by the company's shareholders.

    The NJBCA requires that, prior to making any indemnification, a
determination must be made that the indemnified person has met the applicable
statutory standard of conduct. Unless otherwise provided by the corporation's
certificate of incorporation or bylaws, that determination is made by (i) a
quorum of disinterested directors or a committee thereof, (ii) independent legal
counsel if so directed by a quorum of disinterested directors or if a quorum of
disinterested directors is not obtainable, or (iii) by the company's
shareholders if so directed by the certificate of incorporation, bylaws or a
resolution of the board of directors or shareholders.

    Both statutes allow for the advance payment of expenses prior to the final
disposition of an action upon receipt of an undertaking by or on behalf of such
director or officer to repay such amount if it shall ultimately be determined
that such person is not entitled to be indemnified by the company.

    The NJBCA permits a corporation to provide in its certificate of
incorporation that a director or officer will not be personally liable to the
corporation or its shareholders for breach of any duty owed to the corporation
or its shareholders except that such provision will not relieve a director or
officer from liability based upon an act or omission:

    - in breach of such person's duty of loyalty to the corporation or its
      shareholders,

    - not it good faith or involving a violation of law, or

    - resulting in receipt by such person of an improper personal benefit

    The NYBCL contains a similar provision, but allows a corporation so to limit
the liability only of directors, not officers, of the corporation.

    The GE charter provides that a person who is or was a director of GE will
have no personal liability to GE or its stockholders for damages for any breach
of duty except there is no limitation of liability where such liability is
imposed under the NYBCL. The GE bylaws provide that GE shall, to the fullest
extent permitted by applicable law, indemnify any person who is or was or has
agreed to become a director of GE against damages, provided that no
indemnification may be provided to any person if a judgment or other final
adjudication adverse to the director establishes that

    - his or her acts were committed in bad faith or were the result of active
      and deliberate dishonesty and, in either case, were material to the cause
      of action so adjudicated, or

                                       64

    - he or she personally gained a financial profit or other advantage to which
      he or she was not legally entitled

    The Imatron bylaws provide that directors, officers and employees of the
corporation will be indemnified by the corporation against expenses, judgments,
fines and amounts paid in settlement for actions taken by them which they
believed to be in the best interests in, or not opposed to the best interests
of, the corporation, and, with respect to criminal actions, had no reasonable
cause to believe their conduct was unlawful. The corporation's determination
that an individual has a right to indemnification will be made in accordance
with the requirements of the NJBCA.

                       DESCRIPTION OF GE'S CAPITAL STOCK

    SET FORTH BELOW IS A DESCRIPTION OF THE GE COMMON STOCK. THE FOLLOWING
STATEMENTS ARE BRIEF SUMMARIES OF, AND ARE SUBJECT TO THE DETAILED PROVISIONS
OF, THE GE CHARTER, THE GE BYLAWS AND THE RELEVANT PROVISIONS OF THE NEW YORK
CORPORATE LAW.

    GE currently is authorized to issue up to 13,200,000,000 shares of common
stock, par value $.06 per share. GE is also authorized to issue up to 50,000,000
shares of preferred stock, par value $1.00 per share, in series. GE has not
issued any of this preferred stock. If preferred stock is issued, GE's board of
directors may fix the designation, relative rights, preferences and limitations
of the shares of each series.

    Dividends may be paid on the GE common stock out of funds legally available
for dividends, when and if declared by GE's board of directors.

    Holders of the GE common stock are entitled to share ratably in any
dividends and in any assets available for distribution on liquidation,
dissolution or winding up, subject, if preferred stock of GE is then
outstanding, to any preferential rights of such preferred stock. Each share of
GE common stock entitles the holder thereof to one vote at all meetings of
stockholders, and the votes are noncumulative. The GE common stock is not
redeemable, has no subscription or conversion rights and does not entitle the
holder thereof to any preemptive rights.

                                 LEGAL MATTERS

    Robert E. Healing, Corporate Counsel of GE, will pass upon the validity of
the GE common stock to be issued in connection with the merger. Mr. Healing
beneficially owns or has rights to acquire an aggregate of less than 0.01% of
GE's common stock. Gibson, Dunn & Crutcher LLP, counsel to GE, and Allen Matkins
Leck Gamble & Mallory LLP, counsel to Imatron, will deliver opinions concerning
the federal income tax consequences of the merger.

                          AGREEMENT AND PLAN OF MERGER

    This AGREEMENT AND PLAN OF MERGER, dated as of September 21, 2001 (this
"AGREEMENT"), is among General Electric Company, a New York corporation
("PARENT"), Ruby Merger Corp., a New Jersey corporation and a wholly-owned
subsidiary of Parent ("SUB"), and Imatron Inc., a New Jersey corporation (the
"COMPANY") (Sub and the Company being hereinafter collectively referred to as
the "CONSTITUENT CORPORATIONS").

                                   RECITALS:

    A. The respective Boards of Directors of Parent, Sub and the Company have
approved and declared advisable the merger of Sub with and into the Company upon
the terms and subject to the conditions of this Agreement (the "MERGER"), and
the respective Boards of Directors of Parent, Sub and the Company have approved
and adopted this Agreement;

    B.  Based upon their expectations that the Merger will further certain
business objectives of the Sub and the Company (including, without limitation,
diversification and the realization of economies of scale), the respective
Boards of Directors of Sub and the Company have determined that the Merger is in
the best interest of their respective shareholders;

    C.  In order to induce Parent and Sub to enter into this Agreement,
concurrently herewith (i) Parent and the Company are entering into the Stock
Option Agreement dated as of the date hereof (the "STOCK OPTION AGREEMENT") in
the form of the attached EXHIBIT A and (ii) Parent and certain of the
shareholders of the Company are entering into the Shareholder Agreement dated as
of the date hereof (the "SHAREHOLDER AGREEMENT") in the form of the attached
EXHIBIT B; and

    D. For federal income tax purposes, it is intended by the parties hereto
that the Merger shall qualify as a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, and the rules
and regulations promulgated thereunder (the "CODE").

    NOW, THEREFORE, in consideration of the premises, representations,
warranties and agreements herein contained, the parties agree as follows:

                                   ARTICLE I
                                 PLAN OF MERGER

    SECTION 1.1  THE MERGER.  Upon the terms and subject to the conditions
hereof, and in accordance with the New Jersey Business Corporation Act (the
"NJBCA"), Sub shall be merged with and into the Company at the Effective Time
(as defined in Section 1.2). Following the Merger, the separate corporate
existence of Sub shall cease and the Company shall continue as the surviving
corporation (the "SURVIVING CORPORATION") and shall succeed to and assume all
the rights and obligations of Sub in accordance with the NJBCA. Notwithstanding
anything to the contrary herein, at the election of Parent, any direct
wholly-owned Subsidiary (as hereinafter defined) of Parent may be substituted
for Sub as a constituent corporation in the Merger. In such event, the parties
agree to execute an appropriate amendment to this Agreement, in form and
substance reasonably satisfactory to Parent and the Company, in order to reflect
such substitution.

    SECTION 1.2  EFFECTIVE TIME.  The Merger shall become effective when the
certificate of merger (the "CERTIFICATE OF MERGER"), executed in accordance with
the relevant provisions of the NJBCA, and attaching the "PLAN OF MERGER" in the
form of Exhibit C, is filed with the Treasurer of the State of New Jersey;
provided, however, that, upon mutual consent of the Constituent Corporations,
the Certificate of Merger may provide for a later date of effectiveness of the
Merger not more than 90 days after the date the Certificate of Merger is filed.
When used in this Agreement, the term "EFFECTIVE TIME" shall mean the date and
time at which the Certificate of Merger is accepted for filing or such later
time

                                      A-1

established by the Certificate of Merger. The filing of the Certificate of
Merger shall be made on the date of the Closing (as defined in Section 1.14).

    SECTION 1.3  EFFECTS OF THE MERGER.  The Merger shall have the effects set
forth in this Agreement and applicable provisions of the NJBCA.

    SECTION 1.4  CHARTER AND BY-LAWS; DIRECTORS AND OFFICERS.

        (a) The Certificate of Incorporation of the Company in effect at the
    Effective Time will be amended in its entirety at the Effective Time to read
    as set forth in EXHIBIT D hereto and shall be the Certificate of
    Incorporation of the Surviving Corporation until thereafter changed or
    amended as provided therein or by applicable law. The By-laws of Sub in
    effect at the Effective Time will be the By-laws of the Surviving
    Corporation until thereafter changed or amended as provided therein or by
    applicable law.

        (b) The directors of Sub at the Effective Time shall automatically, and
    without further action, be the directors of the Surviving Corporation, until
    the earlier of their resignation or removal or until their respective
    successors are duly elected and qualified, as the case may be. The officers
    of Sub at the Effective Time shall be the officers of the Surviving
    Corporation, until the earlier of their resignation or removal or until
    their respective successors are duly elected and qualified, as the case may
    be.

    SECTION 1.5  CONVERSION OF SECURITIES.  As of the Effective Time, by virtue
of the Merger and without any action on the part of Sub, the Company or the
holders of any securities of the Constituent Corporations:

        (a) Each issued and outstanding share of common stock, no par value per
    share, of Sub shall be converted into one validly issued, fully paid and
    nonassessable share of common stock of the Surviving Corporation.

        (b) All shares of Company Common Stock that are owned by Parent or Sub
    shall automatically be canceled and retired and shall cease to exist and no
    capital stock of Parent or other consideration shall be delivered in
    exchange therefor.

        (c) Subject to the provisions of Section 1.8 hereof, each share of
    Common Stock, no par value per share, of the Company ("COMPANY COMMON
    STOCK") issued and outstanding immediately prior to the Effective Time
    (other than shares to be canceled in accordance with Section 1.5(b)) shall
    be converted into the right to receive the number of shares of common stock,
    par value $0.06 per share, of the Parent ("PARENT COMMON STOCK") determined
    by dividing $1.89 by the Average Parent Share Price (as defined below) and
    rounding the result to the nearest one thousandth of a share (the "MERGER
    CONSIDERATION"); provided, however, that if between the first day of the
    Valuation Period (as defined below) and the Effective Time, the outstanding
    shares of Parent Common Stock shall have been changed into a different
    number of shares or a different class, by reason of any stock dividend,
    subdivision, reclassification, recapitalization, split, combination or
    exchange of shares, the Merger Consideration shall be correspondingly
    adjusted to the extent appropriate to reflect such stock dividend,
    subdivision, reclassification, recapitalization, split, combination or
    exchange of shares. The "AVERAGE PARENT SHARE PRICE" means the average of
    the daily volume-weighted sales prices per share of Parent Common Stock on
    the New York Stock Exchange Tape for each of the 10 consecutive trading days
    ending on the trading day which is five calendar days prior to the Closing
    Date, or, if such ending date does not fall on a trading day, then the
    trading day immediately preceding the fifth calendar day prior to the
    Closing Date (the "VALUATION PERIOD"). All such shares of Company Common
    Stock, when so converted, shall no longer be outstanding and shall
    automatically be canceled and retired and each holder of a certificate
    representing any such shares shall cease to have any rights with respect
    thereto, except the right to receive any dividends and other distributions
    in accordance with Section 1.7,

                                      A-2

    certificates representing the shares of Parent Common Stock into which such
    shares are converted and any cash, without interest, in lieu of fractional
    shares to be issued or paid in consideration therefor upon the surrender of
    such certificate in accordance with Section 1.6.

    SECTION 1.6  PARENT TO MAKE CERTIFICATES AVAILABLE.

        (a) EXCHANGE OF CERTIFICATES.  Parent shall authorize a bank, trust
    company, or such other person or persons as shall be reasonably acceptable
    to Parent and the Company, to act as Exchange Agent hereunder (the "EXCHANGE
    AGENT"). As soon as practicable after the Effective Time, Parent shall
    deposit with the Exchange Agent, in trust for the holders of shares of
    Company Common Stock converted in the Merger, certificates representing the
    shares of Parent Common Stock issuable pursuant to Section 1.5(c) in
    exchange for outstanding shares of Company Common Stock and cash, as
    required to make payments in lieu of any fractional shares pursuant to
    Section 1.8 (such cash and shares of Parent Common Stock, together with any
    dividends or distributions with respect thereto, being hereinafter referred
    to as the "EXCHANGE FUND"). The Exchange Agent shall deliver the Parent
    Common Stock contemplated to be issued pursuant to Section 1.5(c) out of the
    Exchange Fund. Except as contemplated by Section 1.9, the Exchange Fund
    shall not be used for any other purpose.

        (b) EXCHANGE PROCEDURES.  As soon as practicable after the Effective
    Time, the Exchange Agent shall mail to each record holder of a certificate
    or certificates which immediately prior to the Effective Time represented
    outstanding shares of Company Common Stock converted in the Merger (the
    "CERTIFICATES") a letter of transmittal (which shall specify that delivery
    shall be effected, and risk of loss and title to the Certificates shall
    pass, only upon actual delivery of the Certificates to the Exchange Agent,
    and shall contain instructions for use in effecting the surrender of the
    Certificates in exchange for certificates representing shares of Parent
    Common Stock and cash in lieu of fractional shares). Upon surrender for
    cancellation to the Exchange Agent of a Certificate held by any record
    holder of a Certificate, together with such letter of transmittal, duly
    executed, the holder of such Certificate shall be entitled to receive in
    exchange therefor a certificate representing that number of whole shares of
    Parent Common Stock into which the shares represented by the surrendered
    Certificate shall have been converted at the Effective Time pursuant to this
    Article I, cash in lieu of any fractional share in accordance with
    Section 1.8 and certain dividends and other distributions in accordance with
    Section 1.7, and any Certificate so surrendered shall forthwith be canceled.

    SECTION 1.7  DIVIDENDS; TRANSFER TAXES; WITHHOLDING.  No dividends or other
distributions that are declared on or after the Effective Time on Parent Common
Stock, or are payable to the holders of record thereof on or after the Effective
Time, will be paid to any person entitled by reason of the Merger to receive a
certificate representing Parent Common Stock until such person surrenders the
related Certificate or Certificates, as provided in Section 1.6, and no cash
payment in lieu of fractional shares will be paid to any such person pursuant to
Section 1.8 until such person shall so surrender the related Certificate or
Certificates. Subject to the effect of applicable law, there shall be paid to
each record holder of a new certificate representing such Parent Common Stock:
(a) at the time of such surrender or as promptly as practicable thereafter, the
amount of any dividends or other distributions theretofore paid with respect to
the shares of Parent Common Stock represented by such new certificate and having
a record date on or after the Effective Time and a payment date prior to such
surrender; (b) at the appropriate payment date or as promptly as practicable
thereafter, the amount of any dividends or other distributions payable with
respect to such shares of Parent Common Stock and having a record date on or
after the Effective Time but prior to such surrender and a payment date on or
subsequent to such surrender; and (c) at the time of such surrender or as
promptly as practicable thereafter, the amount of any cash payable with respect
to a fractional share of Parent Common Stock to which such holder is entitled
pursuant to Section 1.8. In no event shall the person entitled to receive such
dividends or other distributions be entitled to receive interest on such
dividends or other

                                      A-3

distributions. If any cash or certificate representing shares of Parent Common
Stock is to be paid to or issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it shall be a
condition of such exchange that the Certificate so surrendered shall be properly
endorsed and otherwise in proper form for transfer and that the person
requesting such exchange shall pay to the Exchange Agent any transfer or other
taxes required by reason of the issuance of certificates for such shares of
Parent Common Stock in a name other than that of the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of the Exchange
Agent that such tax has been paid or is not applicable. Parent or the Exchange
Agent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of Company Common
Stock such amounts as Parent or the Exchange Agent is required to deduct and
withhold with respect to the making of such payment under the Code or under any
provision of state, local or foreign tax law. To the extent that amounts are so
withheld by Parent or the Exchange Agent, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Company Common Stock in respect of which such deduction and
withholding was made by Parent or the Exchange Agent.

    SECTION 1.8  NO FRACTIONAL SECURITIES.  No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Certificates pursuant to this Article I, and no Parent
dividend or other distribution or stock split shall relate to any fractional
share, and no fractional share shall entitle the owner thereof to vote or to any
other rights of a security holder of Parent. In lieu of any such fractional
share, each holder of Company Common Stock who would otherwise have been
entitled to a fraction of a share of Parent Common Stock upon surrender of
Certificates for exchange pursuant to this Article I will be paid an amount in
cash (without interest), rounded to the nearest cent, determined by multiplying
(a) the Average Parent Share Price by (b) the fractional interest to which such
holder would otherwise be entitled. As promptly as practicable after the
determination of the amount of cash, if any, to be paid to holders of fractional
share interests, the Exchange Agent shall so notify the Parent, and the Parent
shall deposit such amount with the Exchange Agent and shall cause the Exchange
Agent to forward payments to such holders of fractional share interests subject
to and in accordance with the terms of Section 1.7 and this Section 1.8.

    SECTION 1.9  RETURN OF EXCHANGE FUND.  Any portion of the Exchange Fund
which remains undistributed to the former shareholders of the Company for six
months after the Effective Time shall be delivered to Parent, upon demand of
Parent, and any such former shareholders who have not theretofore complied with
this Article I shall thereafter look only to Parent for payment of their claim
for Parent Common Stock, any cash in lieu of fractional shares of Parent Common
Stock and any dividends or distributions with respect to Parent Common Stock.
Neither Parent nor the Surviving Corporation shall be liable to any former
holder of Company Common Stock for any such shares of Parent Common Stock, cash
and dividends and distributions held in the Exchange Fund which is delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.

    SECTION 1.10  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All
shares of Parent Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms hereof (including any cash paid
pursuant to Sections 1.7 and 1.8) shall be deemed to have been issued in full
satisfaction of all rights pertaining to the shares of Company Common Stock
represented by such Certificates.

    SECTION 1.11  CLOSING OF COMPANY TRANSFER BOOKS.  At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of shares of
Company Common Stock shall thereafter be made on the records of the Company. If,
after the Effective Time, Certificates are presented to the Surviving
Corporation, the Exchange Agent or the Parent, such Certificates shall be
canceled and exchanged as provided in this Article I.

                                      A-4

    SECTION 1.12  LOST CERTIFICATES.  If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Parent or the Exchange Agent, the posting by such person of a bond, in such
reasonable amount as Parent or the Exchange Agent may direct as indemnity
against any claim that may be made against them with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the shares of Parent Common Stock, any cash in lieu of
fractional shares of Parent Common Stock to which the holders thereof are
entitled pursuant to Section 1.8 and any dividends or other distributions to
which the holders thereof are entitled pursuant to Section 1.7.

    SECTION 1.13  FURTHER ASSURANCES.  If at any time after the Effective Time
the Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation its right, title or interest in, to or under any of
the rights, privileges, powers, franchises, properties or assets of either of
the Constituent Corporations, or (b) otherwise to carry out the purposes of this
Agreement, the Surviving Corporation and its proper officers and directors or
their designees shall be authorized to execute and deliver, in the name and on
behalf of either of the Constituent Corporations, all such deeds, bills of sale,
assignments and assurances and to do, in the name and on behalf of either
Constituent Corporation, all such other acts and things as may be necessary,
desirable or proper to vest, perfect or confirm the Surviving Corporation's
right, title or interest in, to or under any of the rights, privileges, powers,
franchises, properties or assets of such Constituent Corporation and otherwise
to carry out the purposes of this Agreement.

    SECTION 1.14  CLOSING.  The closing of the transactions contemplated by this
Agreement (the "CLOSING") and all actions specified in this Agreement to occur
at the Closing shall take place at the offices of Gibson, Dunn & Crutcher LLP,
One Montgomery Street, San Francisco, California 94104, at 10:00 a.m., local
time, no later than the second business day following the day on which the last
of the conditions set forth in Article VI shall have been fulfilled or waived
(if permissible) (the "CLOSING DATE") or at such other time and place as Parent
and the Company shall agree.

                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES
                               OF PARENT AND SUB

    Parent and Sub represent and warrant to the Company as follows:

    SECTION 2.1  ORGANIZATION, STANDING AND POWER.  Each of Parent and Sub is a
corporation duly organized, validly existing and in good standing under the laws
of its place of incorporation and has the requisite corporate power and
authority to carry on its business as now being conducted. Each of Parent and
Sub are duly qualified to do business, and are in good standing, in each
jurisdiction where the character of their properties owned or held under lease
or the nature of their activities makes such qualification necessary, except
where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect on Parent. For purposes of this
Agreement, "MATERIAL ADVERSE CHANGE" or "MATERIAL ADVERSE EFFECT" means, when
used with respect to Parent, any change or effect that is or could reasonably be
expected (as far as can be foreseen at the time) to be materially adverse to the
business, operations, properties, assets, liabilities, employee relationships,
customer or supplier relationships, earnings or results of operations, financial
projections or forecasts, or the business prospects and condition of Parent and
its Subsidiaries, taken as a whole.

    SECTION 2.2  AUTHORITY.  On or prior to the date of this Agreement, the
Board of Directors of Sub shall have declared the Merger advisable and have
approved and adopted this Agreement in accordance with the NJBCA. Each of Parent
and Sub has all requisite corporate power and authority

                                      A-5

to enter into this Agreement, Parent has all requisite corporate power and
authority to enter into the Stock Option Agreement and the Shareholder
Agreement, and to consummate the transactions contemplated hereby and thereby.
The execution and delivery of this Agreement by Parent and Sub, the execution
and delivery of the Stock Option Agreement and the Shareholder Agreement by
Parent and the consummation by Parent and Sub of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate action
(including all Board action) on the part of Parent and Sub, subject to the
filing of appropriate Certificate of Merger as required by the NJBCA. This
Agreement has been duly executed and delivered by Parent and Sub, the Stock
Option Agreement and the Shareholder Agreement have been duly executed and
delivered by Parent, and (assuming the valid authorization, execution and
delivery of this Agreement and the Stock Option Agreement by the Company, the
valid authorization, execution and delivery of the Shareholder Agreement by the
shareholder of the Company that is a party thereto and the validity and binding
effect hereof and thereof on the Company and such shareholder) this Agreement
constitutes the valid and binding obligation of Parent and Sub enforceable
against each of them in accordance with its terms and the Stock Option Agreement
and the Shareholder Agreement constitute a valid and binding obligation of
Parent enforceable against Parent in accordance with its terms. The filing of a
registration statement on Form S-4 with the Securities and Exchange Commission
(the "SEC") by Parent under the Securities Act of 1933, as amended (together
with the rules and regulations promulgated thereunder, the "SECURITIES ACT"),
for the purpose of registering the shares of Parent Common Stock to be issued in
the Merger (together with any amendments or supplements thereto, whether prior
to or after the effective date thereof, the "REGISTRATION STATEMENT") has been
duly authorized by Parent's Board of Directors.

    SECTION 2.3  CONSENTS AND APPROVALS; NO VIOLATION.  Assuming that all
consents, approvals, authorizations and other actions described in this
Section 2.3 have been obtained and all filings and obligations described in this
Section 2.3 have been made, the execution and delivery of this Agreement, the
Stock Option Agreement and the Shareholder Agreement do not, and the
consummation of the transactions contemplated hereby and thereby and compliance
with the provisions hereof and thereof will not, result in any violation of, or
default (with or without notice or lapse of time, or both) under, or give to
others a right of termination, cancellation or acceleration of any obligation or
result in the loss of a material benefit under, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the properties or
assets of Parent or any of its Subsidiaries under, any provision of (a) the
Certificate of Incorporation or the By-laws of Parent, each as amended to date,
(b) any provision of the comparable charter or organization documents of any of
Parent's Subsidiaries, (c) any loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise
or license applicable to Parent or any of its Subsidiaries or (d) any judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to Parent
or any of its Subsidiaries or any of their respective properties or assets,
other than, in the case of clauses (b), (c) or (d), any such violations,
defaults, rights, losses, liens, security interests, charges or encumbrances
that, individually or in the aggregate, would not have a Material Adverse Effect
on Parent, materially impair the ability of Parent or Sub to perform their
respective obligations hereunder or under the Stock Option Agreement or the
Shareholder Agreement or prevent the consummation of any of the transactions
contemplated hereby or thereby. No filing or registration with, or
authorization, consent or approval of, any domestic (federal and state), foreign
or supranational court, commission, governmental body, regulatory agency,
authority or tribunal (a "GOVERNMENTAL ENTITY") is required by or with respect
to Parent or any of its Subsidiaries in connection with the execution and
delivery of this Agreement, the Stock Option Agreement or the Shareholder
Agreement by Parent or Sub or is necessary for the consummation of the Merger
and the other transactions contemplated by this Agreement, the Stock Option
Agreement or the Shareholder Agreement, except for (i) in connection, or in
compliance, with the provisions of the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR ACT"), the Securities Act and the Securities
Exchange Act of 1934, as amended (together with the rules and regulations
promulgated thereunder, the "EXCHANGE ACT"), (ii) the filing of the Certificate
of

                                      A-6

Merger with the Secretary of State of the State of New Jersey and appropriate
documents with the relevant authorities of other states in which the Company or
any of its Subsidiaries is qualified to do business, (iii) such filings and
consents as may be required under any environmental, health or safety law or
regulation pertaining to any notification, disclosure or required approval
triggered by the Merger or by the transactions contemplated by this Agreement,
the Stock Option Agreement, or the Shareholder Agreement, (iv) such filings,
authorizations, orders and approvals as may be required by state takeover laws
(the "STATE TAKEOVER APPROVALS"), (v) applicable requirements, if any, of state
securities or "blue sky" laws ("BLUE SKY LAWS") and the New York Stock Exchange
(the "NYSE"), (vi) as may be required under foreign laws and (vii) such other
consents, orders, authorizations, registrations, declarations, approvals and
filings the failure of which to be obtained or made would not, individually or
in the aggregate, have a Material Adverse Effect on Parent, materially impair
the ability of Parent or Sub to perform its obligations hereunder or under the
Stock Option Agreement or the Shareholder Agreement or prevent the consummation
of any of the transactions contemplated hereby or thereby.

    SECTION 2.4  PARENT COMMON STOCK TO BE ISSUED IN THE MERGER.  All of the
shares of Parent Common Stock issuable in exchange for Company Common Stock at
the Effective Time in accordance with this Agreement will be, when so issued,
duly authorized, validly issued, fully paid and nonassessable and free of
preemptive rights created by statute, Parent's Certificate of Incorporation or
By-laws or any agreement to which Parent is a party or by which Parent is bound
and will, when issued, be registered under the Securities Act and the Exchange
Act and registered or exempt from registration under applicable Blue Sky laws.

    SECTION 2.5  SEC DOCUMENTS AND OTHER REPORTS.  Parent has filed all required
documents with the SEC since January 1, 1996 (the "PARENT SEC DOCUMENTS"). As of
their respective dates, the Parent SEC Documents complied in all material
respects with the requirements of the Securities Act or the Exchange Act, as the
case may be, and, at the respective times they were filed, none of the Parent
SEC Documents contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The consolidated financial statements (including, in each case,
any notes thereto) of Parent included in the Parent SEC Documents complied as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto, were prepared
in accordance with United States generally accepted accounting principles
(except, in the case of the unaudited statements, as permitted by Form 10-Q of
the SEC) applied on a consistent basis during the periods involved (except as
may be indicated therein or in the notes thereto) and fairly presented in all
material respects the consolidated financial position of Parent and its
consolidated Subsidiaries as at the respective dates thereof and the
consolidated results of their operations and their consolidated cash flows for
the periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments and to any other adjustments described therein).
Except as disclosed in the Parent SEC Documents or as required by generally
accepted accounting principles, Parent has not, since June 30, 2001, made any
change in the accounting practices or policies applied in the preparation of
financial statements.

    SECTION 2.6  REGISTRATION STATEMENT AND PROXY STATEMENT.  None of the
information to be supplied in writing by Parent or Sub for inclusion or
incorporation by reference in the Registration Statement or the proxy
statement/prospectus included therein (together with any amendments or
supplements thereto, the "PROXY STATEMENT") relating to the Shareholder Meeting
(as defined in Section 5.1) will (a) in the case of the Registration Statement,
at the time it becomes effective, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein not misleading or (b) in the
case of the Proxy Statement, at the time of the mailing of the Proxy Statement,
at the time of the Shareholder Meeting and at the Effective Time, contain any
untrue statement of a material fact or omit to state any material

                                      A-7

fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. If at any time prior to the Effective Time any event with respect to
Parent, its officers and directors or any of its Subsidiaries shall occur which
is required to be described in the Proxy Statement or the Registration
Statement, such event shall be so described, and an appropriate amendment or
supplement shall be promptly filed with the SEC and, as required by law,
disseminated to the shareholders of the Company. The Registration Statement will
comply (with respect to Parent) as to form in all material respects with the
provisions of the Securities Act, and the Proxy Statement will comply (with
respect to Parent) as to form in all material respects with the provisions of
the Exchange Act.

    SECTION 2.7  BROKERS.  No broker, investment banker or other person, is
entitled to any broker's, finder's or other similar fee or commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of Parent or Sub.

    SECTION 2.8  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
the Parent SEC Documents filed with the SEC prior to the date of this Agreement,
since June 30, 2001, there has been no event causing a Material Adverse Effect
on Parent, nor any development that would, individually or in the aggregate,
result in a Material Adverse Effect on Parent.

    SECTION 2.9  REORGANIZATION.  To the actual knowledge of the Vice President
and Senior Counsel of Parent, Taxes, neither Parent nor any affiliate has taken
or agreed to take any action or is aware of any fact with respect to Parent or
its affiliates that would prevent the Merger from qualifying as a reorganization
within the meaning of Section 368(a) of the Code.

    SECTION 2.10  OPERATIONS OF SUB.  Sub is a direct, wholly-owned subsidiary
of Parent, was formed solely for the purpose of engaging in the transactions
contemplated hereby, has engaged in no other business activities and has
conducted its operations only as contemplated hereby.

    SECTION 2.11  OWNERSHIP OF COMPANY COMMON STOCK.  Neither Parent nor any of
its Affiliates is the beneficial owner (as defined in Rule 13d-3 promulgated
under the Exchange Act) of, nor has Parent or any of its Affiliates within the
last three years been the beneficial owner of, Company Common Stock equal to or
greater than ten percent (10%) of the aggregate outstanding Company Common
Stock.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    securities under the Securities Act or (ii) any debt agreements or
    instruments which grant any rights to vote (contingent or otherwise) on
    matters on which shareholders of the Company may vote.

    represented by the Company's ownership in the entity, and the date of
    acquisition of the ownership interest in any such entity.

    SECTION 3.3  AUTHORITY.  On or prior to the date of this Agreement, the

binding effect of the Agreement on Parent and Sub and the Stock Option Agreement
on Parent) constitute the valid and binding obligation of the Company
enforceable against the Company in accordance with its terms. The filing of the
Proxy Statement with the SEC and the issuance of up to 19.9% of the issued and

                                      A-10

consents, approvals, authorizations and other actions described in this
Section 3.4 have been obtained and all filings and obligations described in this
Section 3.4 have been made, the execution and delivery of this Agreement and the
Stock Option Agreement do not, and the consummation of the transactions
contemplated hereby and thereby and compliance with the provisions hereof and
thereof will not, result in any violation of, or default (with or without notice
or lapse of time, or both) under, or give to others a right of termination,
cancellation or acceleration of any obligation or result in the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of the

losses, liens, security interests, charges or encumbrances that, individually or
in the aggregate, would not have a Material Adverse Effect on the Company,
materially impair the ability of the Company to perform its obligations
hereunder or under the Stock Option Agreement or prevent the consummation of any
of the transactions contemplated hereby or thereby. No filing or registration
with, or authorization, consent or approval of, any Governmental Entity is
required by or with respect to the Company or any of its Subsidiaries in

the Stock Option Agreement or prevent the consummation of any of the
transactions contemplated hereby or thereby.

    SECTION 3.5  SEC DOCUMENTS AND OTHER REPORTS.  The Company has filed all

consistent basis during the periods involved (except as may be indicated therein

Subsidiaries is and at all times has been in possession of all franchises,
grants, authorizations, licenses, permits, easements, variances, exceptions,
consents, certificates, approvals and orders of any Governmental Entity
necessary for the Company or any of its Subsidiaries to own, lease and operate
its properties or to carry on its business as it is now being conducted (the
"COMPANY PERMITS"), except where the failure to have any of the Company Permits
would not, individually or in the aggregate, have a Material Adverse Effect on
the Company, and no suspension or cancellation of any of the Company Permits is
pending or, to the Knowledge of the Company (as hereinafter defined),
threatened, except where the suspension or cancellation of any of the Company
Permits would not, individually or in the aggregate, have a Material Adverse
Effect on the Company. Neither the Company nor any of its Subsidiaries is or has
been in violation of (a) its charter, by-laws or other organizational documents,
(b) any applicable law, ordinance, administrative, or governmental rule or
regulation, including any consumer protection, equal opportunity, customs,

respects, with all current applicable statutes, rules, regulations, standards,
guidelines, policies or orders administered or issued by the United States Food
and Drug Administration (the "FDA") or comparable foreign Governmental Entity,
including, but not limited to, FDA's Quality System Regulation,
21 CFR Part 820; the Company does not have knowledge of any facts which furnish
any reasonable basis for any Form FDA-483 observations or regulatory or warning
letters from the FDA, Section 305 notices, or other similar communications from
the FDA or comparable foreign entity; and since March 13, 1997, there have been
no recalls, field notifications, alerts or seizures requested or threatened
relating to the Company's products, except set forth in Section 3.8 of the
Company Letter. The Company's products, where required, are being marketed under
valid 510(k) pre-market notifications cleared by FDA under Section 510(k) of the
Federal Food, Drug, and Cosmetic Act, 21 U.S.C. Section 360(k), and 21 C.F.R.
Part 807, Subpart E ("510(K)S") or pre-market approval applications approved by
the FDA in accordance with 21 U.S.C. Section 360e and 21 C.F.R. Part 814
("PMAS"). All 510(k)s and/or PMAs for the Company's products are exclusively
owned by the Company, and there is no reason to believe that FDA is considering
limiting, suspending, or revoking any such 510(k)s or PMAs or changing the
marketing classification or labeling of any such products. To the Knowledge of
the Company, there is no false information or significant omission in any
product application or product-related submission to the FDA or comparable
foreign Governmental Entity. The Company has obtained all necessary regulatory
approvals from any foreign regulatory agencies related to the products
distributed and sold by the Company. Neither the Company nor any Subsidiary, nor
the officers, directors, managing employees or agents (as those terms are
defined in 42 C.F.R. Section1001.1001) of the Company or any Subsidiary:

civil penalties or mandatory or permissive exclusion from, any Federal Health
Care Program under Sections 1128, 1128A, 1128B, or 1877 of SSA or related state
or local statutes, including knowingly and willfully offering, paying,
soliciting or receiving any remuneration (including any kickback, bribe or

                                      A-13

rebate), directly or indirectly, overtly or covertly, in cash or in kind in
return for, or to induce, the purchase, lease, or order, or the arranging for or
recommending of the purchase, lease or order, of any item or service for which
payment may be made in whole or in part under any such program; (ii) have had a
civil monetary penalty assessed against them under Section 1128A of SSA;

any of the categories of offenses described in Sections 1128(a) or 1128(b)(1),
(b)(2), or (b)(3) of SSA. Except as disclosed in the Company SEC Documents filed
prior to the date of this Agreement (excluding the Risk Factor Disclosures),
there are no contracts or agreements of the Company or its Subsidiaries having
terms or conditions which would have a Material Adverse Effect on the Company or
having covenants not to compete that materially impair the ability of the
Company to conduct its business as currently conducted or would reasonably be
expected to materially impair Parent's ability to conduct its businesses. Except
as set forth in the Company SEC Documents filed prior to the date of this
Agreement (excluding the Risk Factor Disclosures), no event of default or event
that, but for the giving of notice or the lapse of time or both, would
constitute an event of default exists or, upon the consummation by the Company
of the transactions contemplated by this Agreement or the Stock Option
Agreement, will exist under any indenture, mortgage, loan agreement, note or
other agreement or instrument for borrowed money, any guarantee of any agreement
or instrument for borrowed money or any lease, contractual license or other
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any such Subsidiary is bound or to which any of
the properties, assets or operations of the Company or any such Subsidiary is
subject, other than any defaults that, individually or in the aggregate, would
not have a Material Adverse Effect on the Company. "KNOWLEDGE OF THE COMPANY"

    shareholder of the Company or any Subsidiary with access to confidential or
    proprietary information of the Company or any Subsidiary has executed a
    legally binding agreement obligating such employee or consultant to hold
    confidential such proprietary information. To the Knowledge of the Company,
    no officer, director, employee, consultant, agent, or shareholder of the
    Company or any of Subsidiary is in violation of

                                      A-16

    any term of any Compensation Agreement, employment contract, confidentiality
    or non-disclosure agreement or any other contract, agreement, commitment or
    understanding relating to the relationship of such employee, consultant or
    agent with the Company, any Subsidiary, or any other party.

        (b) Set forth in Section 3.11(b) of the Company Letter is a list of all
    contracts that involve payments by the Company of more than $1,000,000 or
    are otherwise material to the business of the Company and its Subsidiaries
    taken as a whole (whether oral or written), including all distribution
    contracts, sole-source supply contracts, national accounts contracts, any
    indenture, mortgage, loan agreement, note or other agreement or instrument
    for borrowed money, any guarantee of any agreement or instrument for
    borrowed money or any material lease, contractual license or other agreement
    or instrument to which the Company or any of its Subsidiaries is a party or
    by which the Company or any such Subsidiary is bound or to which any of the
    properties, assets or operations of the Company or any such Subsidiary is
    subject (collectively, "SIGNIFICANT CONTRACTS"). Prior to the date hereof,
    the Company has provided true and complete copies of all such contracts to
    Parent.

        (c) Except as set forth on Section 3.11(c) of the Company Letter, each

    or its Subsidiaries, neither the Company nor any of its Subsidiaries (or to
    the Knowledge of the Company, any other party thereto) is in default under
    any Significant Contract, and none of such Significant Contracts has been
    canceled by the other party thereto; each Significant Contract is in full
    force and effect and no event has occurred which, with the passage of time
    or the giving of notice or both, would constitute a default, event of
    default or other breach by the Company or any Subsidiary party thereto which
    would entitle the other party to such Significant Contract to terminate the
    same or declare a default or event of default thereunder; the Company and
    the Subsidiaries are not in receipt of any claim of default under any such
    agreement; in each instance, except where it would not have a Material
    Adverse Effect on the Company.

    SECTION 3.12  ERISA

        (a) Each Company Plan is listed in Section 3.12(a) of the Company
    Letter. With respect to each Company Plan, the Company has delivered to
    Parent a true and correct copy of (i) the three most recent annual reports
    (Form 5500) filed with the appropriate agency, to the extent required by the
    Employee Retirement Income Security Act of 1974, as amended, and the rules
    and regulations promulgated thereunder ("ERISA"), (ii) each such Company
    Plan that has been reduced to writing and all amendments thereto,
    (iii) each trust agreement, insurance contract or administration agreement
    relating to each such Company Plan that is funded and the latest financial
    statements thereof, (iv) a written summary of each unwritten Company Plan,
    (v) the most recent summary plan description or other written explanation of
    each Company Plan provided to participants, (vi) the three most recent
    actuarial reports or valuations relating to a Company Plan subject to Title
    IV of ERISA, and the most recent report prepared with respect thereto in
    accordance with Statement of Financial Accounting Standards No. 35,
    (vii) the most recent determination letter and request therefore, if any,
    issued by the IRS with respect to any Company Plan intended to be qualified
    under section 401(a) of the Code, (viii) any request for a determination
    currently pending before the IRS including all correspondence related
    thereto, (ix) all correspondence with the IRS, the Department of Labor, the
    SEC or Pension Benefit Guaranty Corporation relating to any outstanding
    controversy, (x) all forms and certificate samples used to comply with
    Sections 4980B, 9801 and 9802 of the Code, (xi) the amounts of accrued
    benefits under any unfunded Company Plan that defers the receipt of income,
    and (xii) all official filings, plan documents, and computations related to
    COMPANY FOREIGN BENEFIT PLAN (AS DEFINED IN SECTION 3.12(E)). Except as
    would not have a Material Adverse Effect on the Company, each Company Plan
    and the administration thereof complies, and has at all times complied, in
    all

                                      A-17

    respects with ERISA, the Code and all other applicable statutes and
    governmental rules and regulations. Except as set forth in Section 3.12(a)
    of the Company Letter, no "reportable event" (within the meaning of
    Section 4043 of ERISA) has occurred with respect to any Company Plan for
    which the 30-day notice requirement has not been waived and no transaction
    prohibited by Section 406 of ERISA and no "prohibited transaction" under
    Section 4975(c) of the Code has occurred with respect to any Company Plan.
    Neither the Company nor any of its Subsidiaries or ERISA Affiliates (as
    hereinafter defined) has withdrawn from any Company Multiemployer Plan (as
    hereinafter defined) and would not incur any withdrawal liability if it
    withdrew from all Company Multiemployer Plans on the date of this Agreement.
    No action has been taken, or is currently being considered, to terminate or
    withdraw from any Company Plan subject to Title IV of ERISA and there is no
    reason to believe the Pension Benefit Guaranty Corporation would initiate
    the termination of any such Plan. No Company Plan, nor any trust created
    thereunder, has incurred any "accumulated funding deficiency" (as defined in
    Section 302 of ERISA), whether or not waived. All contributions to Company
    Plans that were required to be made under such Plans will have been made as
    of the Closing Date, and all benefits accrued under any unfunded Company
    Plan will have been paid, accrued or otherwise adequately reserved in
    accordance with GAAP, as of such date, and the Company and its ERISA
    Affiliates will have performed by the Closing all material obligations
    required to be performed as of such date under all Company Plans. None of
    the Company any of its Subsidiaries or ERISA Affiliates has any commitment
    or formal plan, whether legally binding or not, to create any additional
    employee benefit plan or modify or change any existing Company Plan that
    would affect any employee or former employee of the Company or any of its
    Subsidiaries or ERISA Affiliates. No person who is not an employee or former
    employee or the surviving spouse, beneficiary or dependent of such an
    employee or former employee of the Company or any Subsidiary or ERISA
    Affiliate is entitled to benefits under any Company Plan.

        (b) Except as listed in Section 3.12(b) of the Company Letter, with
    respect to the Company Plans, no event has occurred and there exists no
    condition or set of circumstances in connection with which the Company or
    any Subsidiary or ERISA Affiliate or Company Plan fiduciary could be subject
    to any liability under the terms of such Company Plans, ERISA, the Code or
    any other applicable law which would have a Material Adverse Effect on the
    Company. All Company Plans that are intended to be qualified under
    Section 401(a) of the Code have been determined by the IRS to be so
    qualified, or a timely application for such determination is now pending,
    and nothing has occurred with respect to the operation of such Company Plans
    which could cause the loss of such qualification or the imposition of any
    liability, penalty or tax under ERISA or the Code. Neither the Company nor
    any of its Subsidiaries or ERISA Affiliates has been notified by any Company
    Multiemployer Plan that such Company Multiemployer Plan is currently in
    reorganization or insolvency under and within the meaning of Section 4241 or
    4245 of ERISA or that such Company Multiemployer Plan intends to terminate
    or has been terminated under Section 4041A of ERISA. No event has occurred
    and there exists no condition or set of circumstances that would result in a
    material increase in the contributions required to be made to any Company
    Multiemployer Plan by the Company or any Subsidiary or ERISA Affiliate.
    Except as disclosed in Section 3.12(b) of the Company Letter, neither the
    Company nor any of its Subsidiaries or ERISA Affiliates has any liability or
    obligation under any welfare plan to provide benefits after termination of
    employment to any employee or dependent other than as required by
    Section 4980B of the Code. The Company and all ERISA Affiliates have at all
    times complied with the notice and continuation requirements of Code
    Section 4980B and ERISA Section 601. Neither the Company nor any ERISA
    Affiliate has incurred any liability for any tax imposed under Section 4971
    through 4980B of the Code or civil liability under Section 502(i) or (1) of
    ERISA.

        (c) As used herein, (i) "COMPANY PLAN" means a "pension plan" (as
    defined in Section 3(2) of ERISA (other than a Company Multiemployer Plan)),
    a "welfare plan" (as defined in

                                      A-18

    benefit, personnel policy, insurance or other plan, arrangement or
    understanding, or any plan or policy required under federal, state, local,
    or foreign law, in each case established, maintained or contributed to by
    the Company or any of its Subsidiaries or ERISA Affiliates or as to which
    the Company or any of its Subsidiaries or ERISA Affiliates has contributed
    or otherwise may have any liability, (ii) "COMPANY MULTIEMPLOYER PLAN" means
    a "multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) to which
    the Company or any of its Subsidiaries or ERISA Affiliates is or has been
    obligated to contribute or otherwise may have any liability, and
    (iii) "ERISA AFFILIATE" means any trade or business (whether or not
    incorporated) which would be considered a single employer with the Company
    pursuant to Section 414(b), (c), (m) or (o) of the Code and the regulations
    promulgated under those sections or pursuant to Section 4001(b) of ERISA and
    the regulations promulgated thereunder.

        (d) Section 3.12(d) of the Company Letter contains a list of all
    (i) severance and employment agreements with employees of the Company and
    each Subsidiary and ERISA Affiliate, (ii) severance programs and policies of
    the Company and each Subsidiary and ERISA Affiliate with or relating to its
    employees and (iii) plans, programs, agreements and other arrangements of
    the Company and each Subsidiary and ERISA Affiliate with or relating to its
    employees containing change of control or similar provisions.

        (e) Except as set forth in Section 3.12(e) of the Company Letter, with
    respect to each Company Plan not subject to United States law (a "COMPANY
    FOREIGN BENEFIT PLAN"), except as would not have a Material Adverse Effect
    on the Company, (i) the fair market value of the assets of each funded
    Company Foreign Benefit Plan, the liability of each insurer for any Company
    Foreign Benefit Plan funded through insurance or the reserve shown on the
    Company's consolidated financial statements for any unfunded Company Foreign
    Benefit Plan, together with any accrued contributions, is sufficient to
    procure or provide for the projected benefit obligations, as of the
    Effective Time, with respect to all current and former participants in such
    plan according reasonable, country specific actuarial assumptions and
    valuations and no transaction contemplated by this Agreement shall cause
    such assets or insurance obligations or book reserve to be less than such
    projected benefit obligations; and (ii) each Company Foreign Benefit Plan
    required to be registered has been registered and has been maintained in
    good standing with the appropriate regulatory authorities. No action has
    been taken, or is currently being considered, to terminate or withdraw from
    any Company Foreign Benefit Plan.

    SECTION 3.13  COMPLIANCE WITH WORKER SAFETY LAWS  The properties, assets and
operations of the Company and its Subsidiaries are in compliance with all
applicable federal, state, local and foreign laws, rules and regulations,
orders, decrees, judgments, permits and licenses relating to public and worker
health and safety (collectively, "WORKER SAFETY LAWS"), except for any
violations that, individually or in the aggregate, would not require
expenditures exceeding $100,000. With respect to such properties, assets and
operations, including any previously owned, leased or operated properties,
assets or operations, there are no past, present or reasonably anticipated
future events, conditions, circumstances, activities, practices, incidents,
actions or plans of the Company or any of its Subsidiaries that may interfere
with or prevent compliance or continued compliance with applicable Worker Safety
Laws, other than any such interference or prevention as would not, individually
or in the aggregate with any such other interference or prevention, require

    than $5,500,000 of indebtedness for borrowed money.

        (b) Since December 31, 1996, neither the Company nor any Subsidiary has
    received a claim for or based upon breach of product or service warranty or
    guaranty or similar claim (other than warranty or guaranty claims in the
    ordinary course of business not material in amount or significance), strict
    liability in tort, negligent design of product, negligent provision of
    services or any other allegation of liability, including or arising from the
    materials, design, testing, manufacture, packaging, labeling (including
    instructions for use), or sale of its products or from the provision of

    agreement between the Company or any of its Subsidiaries and any
    distributor, sales representative, sales agent or other third party who

    Subsidiaries constitutes a valid and binding obligation of the parties
    thereto and is in full force and effect and will continue in full force and
    effect after the Effective Time, in each case, without breaching the terms
    thereof, giving rise to a right of termination thereunder or resulting in
    the forfeiture or impairment of any rights thereunder and without the
    consent, approval or act of, or the making of any filing with, any other
    party. Except as set forth in Section 3.24 of the Company Letter, the

    Subsidiaries; and except as set forth in Section 3.24 of the Company Letter,
    no event has occurred and no condition or state of facts exists which, with

respective properties and assets, and are in character and amount similar to
that carried by persons engaged in similar businesses and subject to the same or
similar perils or hazards, except for any such failures to maintain insurance
policies that, individually or in the aggregate, would not have a Material
Adverse Effect on the Company. The Company and each Subsidiary have made any and
all payments required

                                      A-25

document provided by the Company or its Subsidiaries or any of their respective
employees or agents to Parent in connection with the transactions contemplated
herein contains an untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained therein, in
light of the circumstances under which they are made, not misleading.

    Documents filed with the SEC prior to the date hereof or in Section 3.28 of

    Company complies with its obligations in Section 4.2(b) and in Section 5.1,
    then, to the extent required by the fiduciary obligations of the Board of
    Directors of the Company, as determined in good faith by a majority thereof
    after consultation with independent counsel (who may be the Company's
    regularly engaged independent counsel), the Company may, in response to an
    unsolicited request, furnish non-public information, and afford access to
    the properties, books, records, officers, employees and representatives of
    the Company, participate in discussions or negotiations regarding the
    Superior Proposal and, provided that the Company has complied with the
    provisos to its rights to terminate this Agreement pursuant to
    Section 7.1(g) hereof, enter into an agreement with respect to or approve or
    recommend to its shareholders a Superior Proposal (and, to the extent
    permitted by Section 5.1 hereof, withdraw, modify or change its
    recommendation of this Agreement. Without limiting the foregoing, it is
    understood that any violation of the restrictions set forth in the preceding
    sentence by any officer or director of the Company or any of its
    Subsidiaries or any financial advisor, attorney or other advisor or
    representative of the Company or any of its Subsidiaries, whether or not
    such person is purporting to act on behalf of the Company or any of its
    Subsidiaries or otherwise, shall be deemed to be a breach of this
    Section 4.2(a) by the Company. For purposes of this Agreement, "TAKEOVER
    PROPOSAL" means any proposal for a merger, tender offer or other business
    combination involving the Company or any of its Subsidiaries or any proposal
    or offer to acquire in any manner, directly or indirectly, an equity
    interest in, any voting securities of, or a substantial portion of the
    assets of the Company or any of its Subsidiaries, other than the
    transactions contemplated by this Agreement and the Stock Option Agreement,
    and "SUPERIOR PROPOSAL" means a bona fide proposal made by a third party to
    acquire the Company pursuant to a tender or exchange offer, a merger, a

                                      A-30

    sale of all or substantially all its assets or otherwise on terms which a
    majority of the disinterested members of the Board of Directors of the
    Company determines, at a duly constituted meeting of the Board of Directors
    or by unanimous written consent, in its reasonable good faith judgment
    (after consultation with its financial advisor) to be more favorable to the
    Company's shareholders than the Merger and for which financing, to the
    extent required, is then committed or which, in the reasonable good faith
    judgment of a majority of such disinterested members of the Board of
    Directors of the Company, as expressed in a resolution adopted at a duly
    constituted meeting of such directors, is reasonably capable of being
    obtained by such third party.

        (b) The Company shall advise Parent orally and in writing within
    24 hours of (i) any Takeover Proposal or any inquiry with respect to or
    which could lead to any expression of interest regarding a potential
    Takeover Proposal that is received by or communicated to any officer or
    director of the Company or, to the Knowledge of the Company, any financial
    advisor, attorney or other advisor or representative of the Company,
    (ii) the material terms of such Takeover Proposal (including a copy of any
    written proposal), and (iii) the identity of the person making any such
    Takeover Proposal. If the Company intends to participate in discussions or
    negotiations with and/or furnish any Person with any information with
    respect to any inquiry or Takeover Proposal in accordance with
    Section 4.2(a), the Company shall advise Parent orally and in writing of
    such intention not less than 48 hours in advance of providing such
    information. The Company will keep Parent fully informed of the status and
    details of any such Takeover Proposal or inquiry.

    SECTION 4.3  THIRD PARTY STANDSTILL AGREEMENTS.  During the period from the
date of this Agreement through the Effective Time, the Company shall not
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which the Company or any of its Subsidiaries is a party
(other than any involving Parent). During such period, the Company agrees to
enforce, to the fullest extent permitted under applicable law, the provisions of
any such agreements, including, but not limited to, obtaining injunctions to
prevent any breaches of such agreements and to enforce specifically the terms
and provisions thereof in any court of the United States or any state thereof
having jurisdiction.

    SECTION 4.4  REORGANIZATION.  During the period from the date of this
Agreement through the Effective Time, unless the other party shall otherwise
agree in writing, none of Parent, the Company or any of their respective
Subsidiaries shall take or fail to take any action with the actual knowledge of
those taking or failing to take such action (or those directing such action or
failure to take action) that such action or failure would jeopardize the
qualification of the Merger as a reorganization within the meaning of
Section 368(a) of the Code.

    SECTION 4.5  WARRANTS.  The Parent shall cause the Surviving Corporation to
honor the terms of any warrants outstanding as of the date hereof and listed in
Section 3.2(b) of the Company Letter. The Company will use its best efforts to
obtain a waiver of all registration rights granted by the Company to the persons
listed in Schedule 4.5 of the Company Letter.

                                   ARTICLE V
                             ADDITIONAL AGREEMENTS

    SECTION 5.1  SHAREHOLDER MEETING.  The Company will, as soon as practicable
following the date of this Agreement, duly call, give notice of, convene and
hold a meeting of shareholders (the "SHAREHOLDER MEETING") for the purpose of
considering the approval and adoption of this Agreement and the Plan of Merger
at such meeting call for a vote and cause proxies to be voted in respect of the
approval and adoption of this Agreement. The Company will, through its Board of
Directors, recommend to its shareholders the adoption and approval of this
Agreement and shall not withdraw, modify or change such recommendation;
provided, however, that the Board of Directors of the Company may withdraw,
modify or change such recommendation if it (a) has not breached Section 4.2

                                      A-31

and (b) enters into a merger, acquisition or other agreement (including an
agreement in principle) to effect a Superior Proposal or the Board of Directors
resolves to do so, provided that the Company has complied with the provisos to
its right to terminate this Agreement in Section 7.1(g) of this Agreement.
Notwithstanding the Company's rights regarding a Superior Proposal in the
preceding sentence, the Company agrees that its obligations pursuant to the
first sentence of this Section 5.1 shall not be affected by the commencement,
public proposal, public disclosure or communication to the Company of a Takeover
Proposal or Superior Proposal.

    SECTION 5.2  PREPARATION OF THE REGISTRATION STATEMENT AND THE PROXY
STATEMENT.

        (a) The Company and Parent shall promptly prepare and file with the SEC
    the Proxy Statement and Parent shall prepare and file with the SEC the
    Registration Statement, in which the Proxy Statement will be included as a
    prospectus. Each of Parent and the Company shall use its reasonable best
    efforts to have the Registration Statement declared effective under the
    Securities Act as promptly as practicable after such filing. As promptly as
    practicable after the Registration Statement shall have become effective,
    the Company shall mail the Proxy Statement to its shareholders. If holders
    of warrants set forth in Section 3.2(b) of the Company Letter waive all
    registration rights that would affect Parent Common Stock other than the
    right granted pursuant to this Section (such warrants for which waivers are
    received being referred to herein as "AMENDED WARRANTS") Parent shall
    (i) include in the Registration Statement shares of Common Stock issuable
    upon exercise of the Amended Warrants (ii) convert the Registration
    Statement to a shelf registration which the Parent will keep effective for
    one year following the Effective Time, and (iii) amend the Amended Warrants
    to provide that such warrants may be exercised on a "cashless" or "net
    exercise" basis. Parent shall also take any action (other than qualifying to
    do business in any jurisdiction in which it is now not so qualified)
    required to be taken under any applicable state securities laws in
    connection with the issuance of Parent Common Stock in the Merger and upon
    the exercise of the Substitute Options (as defined in Section 5.7), and the
    Company shall furnish all information concerning the Company and the holders
    of Company Common Stock as may be reasonably requested in connection with
    any such action.

        (b) Parent and the Company promptly will notify each other of the
    receipt of comments from the SEC and of any request by the SEC for
    amendments or supplements to the Registration Statement or the Proxy
    Statement or for additional information, and promptly will supply each other
    with copies of all correspondence between the parties and the SEC with
    respect thereto. If, at any time prior to the Shareholder Meeting, any event
    should occur relating to or affecting the Company, Parent or Sub, or to
    their respective Subsidiaries, officers or directors, which event should be
    described in an amendment or supplement to the Registration Statement or the
    Proxy Statement, the parties promptly will inform each other and cooperate
    in preparing, filing and having declared effective or clearing with the SEC
    and, if required by applicable state securities laws, distributing to the
    Company's shareholders such amendment or supplement.

    SECTION 5.3  ACCESS TO INFORMATION.  Subject to currently existing
contractual and legal restrictions applicable to the Company or any of its
Subsidiaries, the Company shall, and shall cause each of its Subsidiaries to,
and shall instruct their agents and representatives to, afford to the Parent and
its Subsidiaries and each of their accountants, counsel, financial advisors and
other representatives of Parent reasonable access, and permit them to make such
inspections as they may reasonably require of, during the period from the date
of this Agreement through the Effective Time, all of their respective
properties, books, contracts, commitments and records (including engineering
records and Tax Returns and the work papers of independent accountants, if
available and subject to the consent of such independent accountants) and,
during such period, the Company shall, and shall cause each of its Subsidiaries
to (i) furnish promptly to Parent a copy of each report, schedule, registration
statement and other document filed by it during such period pursuant to the
requirements of federal or state securities laws, (ii) consistent with its legal
obligations, furnish promptly to Parent all other information

                                      A-32

concerning its business, properties and personnel as Parent may reasonably
request, (iii) promptly make available to Parent all personnel of the Company
and its Subsidiaries knowledgeable about matters relevant to such inspections as
reasonably requested by Parent and (iv) provide reasonable access to the
Company's and Subsidiaries' facilities and operations to enable Parent to
conduct a health and safety review of the business, including the right to drill
and take samples. No investigation pursuant to this Section 5.3 shall affect any
representation or warranty in this Agreement of any party hereto or any
condition to the obligations of the parties hereto. All information obtained by
Parent pursuant to this Section 5.3 shall be kept confidential in accordance
with the Confidentiality Agreement, dated February 2, 2001, between Parent and
the Company (the "CONFIDENTIALITY AGREEMENT").

    SECTION 5.4  RULE 145 LETTERS.  On the date hereof, the Company shall cause
to be prepared and delivered to Parent a list (reasonably satisfactory to
counsel for Parent) identifying all persons who, at the time of the Shareholder
Meeting, may be deemed to be "affiliates" of the Company as that term is used in
paragraphs (c) and (d) of Rule 145 under the Securities Act (the "RULE 145
AFFILIATES"). The Company shall use its reasonable best efforts to cause each
person who is identified as a Rule 145 Affiliate in such list to deliver to
Parent within 30 days of the date hereof a written agreement in substantially
the form of EXHIBIT E hereto, executed by each of such persons identified in the
foregoing list.

    SECTION 5.5  STOCK EXCHANGE LISTINGS.  Parent shall use its reasonable best
efforts to list on the NYSE, upon official notice of issuance, any shares of
Parent Common Stock to be issued in connection with the Merger or in connection
with Substitute Options that have not been previously listed.

    SECTION 5.6  FEES AND EXPENSES.

        (a) Except as provided in this Section 5.6, whether or not the Merger is
    consummated, all costs and expenses incurred in connection with this
    Agreement and the transactions contemplated hereby, including the fees and
    disbursements of counsel, financial advisors and accountants, shall be paid
    by the party incurring such costs and expenses, provided that all printing
    expenses and all filing fees (including filing fees under the Securities
    Act, the Exchange Act and the HSR Act) shall be divided equally between
    Parent and the Company.

        (b) Notwithstanding any provision in this Agreement to the contrary, if
    this Agreement is terminated (A) by the Company pursuant to
    Section 7.1(d)(i) after receipt of a Superior Proposal, (B) by Parent
    pursuant to Section 7.1(b), (c) or (f), (C) by Parent or the Company
    pursuant to Section 7.1(e) (after receipt of a Superior Proposal or after
    the occurrence of any of the events described in clause (i), (ii) or
    (iii) of Section 7.1(f)) or (g), then, in each case, the Company shall
    (without prejudice to any other rights of Parent against the Company)
    reimburse Parent upon demand for all out-of-pocket fees and expenses
    incurred or paid by or on behalf of Parent or any Affiliate (as hereinafter
    defined) of Parent in connection with this Agreement, the Stock Option
    Agreement and the transactions contemplated herein or therein, including all
    fees and expenses of counsel, investment banking firms, accountants and
    consultants (collectively, "PARENT FEES") up to a maximum of $1,500,000. As
    used herein, "AFFILIATE" shall have the meaning set forth in Rule 405 under
    the Securities Act.

        (c) Notwithstanding any provision in this Agreement to the contrary:

           (i) if this Agreement is terminated:

               (A) by the Company pursuant to Section 7.1(d)(i) after receipt of
           a Superior Proposal, or

               (B) by Parent pursuant to Section 7.1(b) or (f), or

                                      A-33

               (C) by Parent pursuant to Section 7.1(c) or by Parent or the
           Company pursuant to Section 7.1(e) in either case after receipt of a
           Superior Proposal or after the occurrence of any of the events
           described in clause (i), (ii) or (iii) of Section 7.1(f),

       and, in the case of (A), (B) or (C), prior to, concurrently with or
       within twelve months after such a termination a Third Party Acquisition
       Event (as defined below) occurs, then the Company shall (in addition to
       any obligation under Section 5.6(b) and without prejudice to any other
       rights of Parent against the Company) pay to Parent the Termination Fee
       (as defined below) in cash, such payment to be made promptly, but in no
       event later than the second business day following, the later to occur of
       such termination and such Third Party Acquisition Event; or

           (ii) if this Agreement is terminated by Parent or the Company
       pursuant to Section 7.1(g), then the Company shall (in addition to any
       obligation under Section 5.6(b) and without prejudice to any other rights
       of Parent against the Company) pay to Parent the Termination Fee in cash,
       such payment to be made by the Company concurrently with such termination
       if the termination is by the Company, or no later than the second
       business day following such termination if the termination is by Parent.

           "TERMINATION FEE" means $11,000,000, provided, however, that
       (i) such amount shall be reduced to an amount not less than zero by
       subtracting from $11,000,000 the net amount realized or realizable by
       Parent under the Stock Option Agreement, based on the facts as they exist
       on the date such fee shall become due, which net amount shall be
       determined by subtracting any exercise price and underwriting discounts
       or commissions incurred by Parent in connection with the acquisition and
       disposition of the "Optioned Shares" described in the Stock Option
       Agreement, and after giving effect to Section 9(c) thereof, and (ii) the
       total of the Termination Fee and any amount actually realized by Parent
       under the Stock Option Agreement shall not exceed $11,000,000; provided
       further that if such Fee shall be so reduced by an amount so realizable
       by Parent and thereafter the Stock Option Agreement shall terminate
       without receipt by Parent of such amount, then an additional payment
       shall be made to Parent in the amount by which the Termination Fee was
       reduced hereunder promptly following such termination.

           A "THIRD PARTY ACQUISITION EVENT" means any of the following events:
       (A) any person (other than Parent or its Affiliates) acquires or becomes
       the beneficial owner of 20% or more of the outstanding shares of Company
       Common Stock; (B) any group (other than a group which includes or may
       reasonably be deemed to include Parent or any of its Affiliates) is
       formed which, at the time of formation, beneficially owns 20% or more of
       the outstanding shares of Company Common Stock; (C) the Company enters
       into, or announces that it proposes to enter into, an agreement,
       including, an agreement in principle, providing for a merger or other
       business combination involving the Company or a "significant subsidiary"
       (as defined in Rule 1.02(w) of Regulation S-X as promulgated by the SEC)
       of the Company or the acquisition of a substantial interest in, or a
       substantial portion of the assets, business or operations of, the Company
       or a significant subsidiary (other than the transactions contemplated by
       this Agreement); (D) any person (other than Parent or its Affiliates) is
       granted any option or right, conditional or otherwise, to acquire or
       otherwise become the beneficial owner of shares of Company Common Stock
       which, together with all shares of Company Common Stock beneficially
       owned by such person, results or would result in such person being the
       beneficial owner of 20% or more of the outstanding shares of Company
       Common Stock; or (E) there is a public announcement with respect to a
       plan or intention by the Company to effect any of the foregoing
       transactions. For purposes of this Section 5.6(c), the terms "group" and
       "beneficial owner" shall be defined by reference to Section 13(d) of the
       Exchange Act.

                                      A-34

        (d) Notwithstanding any provision in this Agreement to the contrary, if
    this Agreement is terminated (i) by the Company pursuant to Section 7.1(b)
    or (c), then Parent shall (without prejudice to any other rights of the
    Company against Parent) reimburse the Company upon demand for all
    out-of-pocket fees and expenses incurred or paid by or on behalf of the
    Company or any Affiliate of the Company in connection with this Agreement,
    the Stock Option Agreement and the transactions contemplated herein or
    therein, including all fees and expenses of counsel, investment banking
    firms, accountants and consultants (collectively, "COMPANY FEES"), PROVIDED,
    HOWEVER, that (A) in no event shall the amount paid pursuant to this
    Section 5.6(d) in reimbursement of the Company Fees exceed $1,500,000.

    SECTION 5.7  COMPANY STOCK OPTIONS.

        (a) Prior to the Effective Time, the Company shall elect to accelerate
    all Company Stock Options pursuant to its right to do so under the Company
    Stock Option Plans, and shall provide that all such Company Stock Options
    will be cancelled at the Effective Time unless exercised prior thereto,
    except to the extent set forth in Section 5.7(b).

        (b) At the Effective Time, each Company Stock Option that is outstanding
    immediately prior to the Effective Time and that has an exercise or strike
    price less than $1.89 shall become and represent the right to receive a
    number of shares of Parent Common Stock (each a "SUBSTITUTE SHARE"), equal
    to:

       X = A X {[B-(C + T)] / B} X D

    where:

       X = number of Substitute Shares

       A = number of shares of Company Common Stock subject or related to such
           Company Stock Option

       B = $1.89

       C = exercise or purchase price per share of Company Common Stock subject
           or related to such Company Stock Option

       T = all applicable federal, state and local taxes required to be withheld
           by the Parent per share of Company Common Stock subject or related to
           such Company Stock Option

       D = the Merger Consideration

    Parent shall pay cash to holders of Substitute Shares in lieu of issuing
    fractional shares of Parent Common Stock.

        (c) Parent shall offer to employees of the Company who will become
    Employees of the Surviving Corporation or Parent and who hold Company Stock
    Options that are cancelled under Section 5.7(a), and that have exercise
    prices equal to or greater than $1.89 ("CANCELLED OPTIONS"), the election to
    waive any rights associated with the Cancelled Options in exchange for
    options to purchase Parent Common Stock ("PARENT STOCK OPTIONS") on terms
    consistent with options granted to Parent employees generally, which terms
    shall include the following:

           (i) the exercise price of any such Parent Stock Options shall be
       equal to the exercise price of the Cancelled Option divided by the
       Exchange Ratio, where the "EXCHANGE RATIO" is an amount equal to $1.89
       divided by the Average Parent Share Price;

           (ii) the number of shares of Parent Common Stock for which such
       Parent Stock Options shall be exercisable shall be equal to the number of
       shares of Company Common Stock subject to the Cancelled Option multiplied
       by the Exchange Ratio;

                                      A-35

          (iii) the vesting schedule of the Parent Stock Option shall provide
       for annual vesting in September of each year (each a "VESTING DATE");

           (iv) the amount of shares of Parent Common Stock vesting on each
       Vesting Date shall be determined as follows:

               (A) to the extent the Cancelled Option was vested as of the
           Effective Date, the portion of the Parent Stock Option attributable
           to such vested shares shall also be vested; and

               (B) to the extent the Cancelled Option would vest with respect to
           Company Common Stock after the Effective Date, the portion of the
           Parent Stock Option attributable to such unvested shares shall vest
           after the Effective Date on succeeding Vesting Dates such that on
           each Vesting Date, the number of shares of Parent Common Stock
           vesting on each Vesting Date shall equal the number of shares of
           Company Common Stock that would have, but had not already, vested
           over the prior 12-month period under the Cancelled Option.

           (v) Any determination of the extent to which a Cancelled Option is
       vested as of the Effective Date shall be made without regard to the
       operation of this Section 5.7 or any action by the Board of Directors of
       the Company between the date hereof and the Effective Time.

           (vi) Any grants of a Parent Stock Option may, at the request of
       Parent, be made pursuant to and subject to definitive stock option
       agreements between the Parent and each holder of a Cancelled Option.

        (d) The Company shall take all action necessary in implementing the
    provisions of this Section 5.7, including, for avoidance of doubt, amendment
    of the Company Stock Option Plans pursuant to a resolution of the Board of
    Directors in form and substance satisfactory to Parent, to ensure that,
    after giving effect to the foregoing, no Company Stock Option shall be
    exercisable for Company Common Stock or Parent Common Stock following the
    Effective Time.

    SECTION 5.8  REASONABLE BEST EFFORTS.

        (a) Upon the terms and subject to the conditions set forth in this
    Agreement, each of the parties agrees to use reasonable best efforts to
    take, or cause to be taken, all actions, and to do, or cause to be done, and
    to assist and cooperate with the other parties in doing, all things
    necessary, proper or advisable to consummate and make effective, in the most
    expeditious manner practicable, the Merger and the other transactions
    contemplated by this Agreement, including: (i) the obtaining of all
    necessary actions or non-actions, waivers, consents and approvals from all
    Governmental Entities and the making of all necessary registrations and
    filings (including filings with Governmental Entities) and the taking of all
    reasonable steps as may be necessary to obtain an approval or waiver from,
    or to avoid or vigorously defend an action or proceeding by, any
    Governmental Entity (including those in connection with the HSR Act and
    State Takeover Approvals), (ii) the obtaining of all necessary consents,
    approvals or waivers from third parties, (iii) the defending of any lawsuits
    or other legal proceedings, whether judicial or administrative, challenging
    this Agreement, the Stock Option Agreement or the consummation of the
    transactions contemplated hereby and thereby, including seeking to have any
    stay or temporary restraining order entered by any court or other
    Governmental Entity vacated or reversed, and (iv) the execution and delivery
    of any additional instruments necessary to consummate the transactions
    contemplated by this Agreement, including without limitation obtaining the
    waiver, cancellation or voluntary termination of the registration rights
    listed on Schedule 3.2(b) prior to the Closing by the holders thereof to the
    extent that they would otherwise be outstanding after the Merger. No party
    to this Agreement shall consent to any voluntary delay of the consummation
    of the Merger

                                      A-36

    at the behest of any Governmental Entity without the consent of the other
    parties to this Agreement, which consent shall not be unreasonably withheld.

        (b) Each party shall use reasonable best efforts to not take any action,
    or enter into any transaction, which would cause any of its representations
    or warranties contained in this Agreement to be untrue or result in a breach
    of any covenant made by it in this Agreement.

        (c) Notwithstanding anything to the contrary contained in this
    Agreement, in connection with any filing or submission required or action to
    be taken by either Parent or the Company to effect the Merger and to
    consummate the other transactions contemplated hereby, (i) the Company shall
    not, without Parent's prior written consent, commit to any divestiture
    transaction or commit to alter or restrict its business or commercial
    practices in any way, and (ii) neither Parent nor any of its Affiliates
    shall be required to (A) divest or hold separate or otherwise take or commit
    to take any action that limits its freedom of action with respect to, or its
    ability to retain, the Company or any of the businesses, product lines or
    assets of Parent or any of its Affiliates, or (B) alter or restrict in any
    way the business or commercial practices of Parent, any of its Affiliates,
    or the Company.

cause (i) any representation or warranty contained in this Agreement and made by
it to be untrue or inaccurate in any material respect or (ii) any covenant,
condition or agreement contained in this Agreement and made by it not to be
complied with or satisfied in all material respects, (b) any failure of Parent
or the Company, as the case may be, to comply in a timely manner with or satisfy
any covenant, condition or agreement to be complied with or satisfied by it
hereunder or (c) any change or event which would be reasonably likely to have a
Material Adverse Effect on Parent or the Company, as the case may be; PROVIDED,

any such plans which are equity based). For purposes of determining eligibility
to participate, vesting and accrual or entitlement to benefits where length of
service is relevant under any employee benefit plan or arrangement of the

Effective Time shall receive service credit for service with the Company and its
Subsidiaries to the same extent such credit was granted under the Company Plans,
subject to offsets for previously accrued benefits and no duplication of
benefits. Notwithstanding the foregoing, nothing in this Section 5.14 shall
require any action on the part of Parent or the Surviving Corporation with
respect to any employees subject the foreign laws or regulations relating to
employee benefits.

       instrument, except as to which the failure to obtain such consents and

           (ii) Any court or other Governmental Entity having jurisdiction over
       a party hereto shall have issued an order, decree or ruling or taken any

    Proposal, with the intent of enabling Parent to agree to a modification of
    the terms and conditions of this Agreement so that the transactions
    contemplated hereby may be effected; PROVIDED, FURTHER, that the Company may
    not terminate this Agreement pursuant to this Section 7.1(g) unless at the
    end of such 48 hour period the Board of Directors of the Company continues
    reasonably to believe that the Takeover Proposal constitutes a Superior
    Proposal when compared to the Merger (taking into account any such
    modification as may be proposed by Parent) and concurrently with such
    termination the Company pays to Parent the amounts specified under Sections
    5.6(a), (b) and (c);

        (h) By Company if the waiting period applicable to the consummation of
    the Merger under the HSR Act has not expired or been terminated on or prior

Section 7.1 shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers or directors,
whether prior to or after the execution of this Agreement.

    SECTION 7.2  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either Parent or the Company, as provided in Section 7.1, this
Agreement shall forthwith become void and there shall be no liability hereunder
on the part of the Company, Parent, Sub or their respective officers or
directors (except for the last sentence of Section 5.3 and the entirety of
Section 5.6, which shall survive the termination); PROVIDED, HOWEVER, that
nothing contained in this Section 7.2 shall relieve any party hereto from any
liability for any willful breach of a representation or warranty contained in
this Agreement or the breach of any covenant contained in this Agreement.

                                      A-43

    SECTION 7.3  AMENDMENT.  This Agreement may be amended by the parties
hereto, by or pursuant to action taken by their respective Boards of Directors,
in the case of Sub or the Company, or a Senior Vice President of Parent, at any
time before or after approval of the matters presented in connection with the
Merger by the shareholders of the Company, but, after any such approval, no
amendment shall be made which by law or the rules of the Nasdaq National Market
requires further approval by such shareholders without such further approval.
This Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto.

    SECTION 7.4  WAIVER.  At any time prior to the Effective Time, the parties
hereto may (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions contained herein which may legally be waived. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in an instrument in writing signed on behalf of such party. No delay
on the part of any party hereto in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any waiver on the part of
any party hereto of any right, power or privilege hereunder operate as a waiver
of any other right, power or privilege hereunder, nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege hereunder. Unless otherwise provided, the rights and remedies herein
provided are cumulative and are not exclusive of any rights or remedies which
the parties hereto may otherwise have at law or in equity. The failure of any

September 21, 2001

Imatron Inc.
Board of Directors
389 Oyster Point Boulevard
South San Francisco, CA 94080

Members of the Board:

    We understand that the General Electric Company, a New York corporation
("Parent"), Ruby Merger Corp., a New Jersey corporation and a subsidiary of
Parent ("Merger Sub"), and Imatron Inc., a New Jersey corporation ("Company"),
propose to enter into an Agreement and Plan of Merger (the "Merger Agreement")
pursuant to which Merger Sub will be merged with and into Company, which will be
the surviving entity (the "Merger"). Pursuant to the Merger, as more fully
described in the draft dated September 20, 2001 of the Merger Agreement, each
issued and outstanding share of common stock, no par value per share, of Company
("Company Common Stock"), excluding shares held by Parent or Merger Sub, will be
converted into the right to receive that number of shares of common stock, $0.06
par value per share, of Parent ("Parent Common Stock") determined by dividing
$1.89 by the average of the daily volume-weighted sales prices per share of
Parent Common Stock on the New York Stock Exchange Tape for each of the ten
consecutive trading days ending on the trading day which is five calendar days
prior to the closing of the Merger, or, if such ending date does not fall on a
trading day, then the trading day immediately preceding the fifth calendar day
prior to the closing of the Merger, subject to certain adjustments (such
consideration to be paid pursuant to the Merger for each share of Company Common
Stock shall hereinafter be referred to as the "Merger Consideration"). The terms
and conditions of the Merger are set forth in more detail in the Merger
Agreement.

    You have asked for our opinion as investment bankers as to whether the
Merger Consideration to be received by the shareholders of Company (other than
Parent and Merger Sub) pursuant to the Merger is fair to such shareholders from
a financial point of view, as of the date hereof. As you are aware, we were not
retained to nor did we advise Company with respect to alternatives to the Merger
or Company's underlying decision to proceed with or effect the Merger. Further,
we were not requested to nor did we solicit or assist Company in soliciting
indications of interest from third parties for all or any part of Company.

    In connection with our opinion, we have, among other things, (i) reviewed
certain publicly available financial and other data with respect to Company and
Parent, including the consolidated financial statements for the most recent year
ending December 31, 2000 and the interim periods ending June 30, 2001 and
certain other relevant financial and operating data relating to Company and
Parent made available to us from published sources and from the internal records
of Company; (ii) reviewed the financial terms and conditions of the draft dated
September 20, 2001 of the Merger Agreement; (iii) reviewed certain publicly
available information concerning the stock market trading history for Parent
Common Stock and Company Common Stock; (iv) compared Company and Parent from a
financial point of view with certain other companies in the medical equipment
industry which we deem to be relevant; (v) considered the financial terms, to
the extent publicly available, of selected recent business combinations of
companies in the medical equipment industry which we deemed to be comparable, in
whole or in part, to the Merger; (vi) reviewed and discussed with
representatives of the management of Company certain information of a business
and financial nature regarding Company, furnished to us by them, including
financial forecasts and related assumptions of Company; (vii) made

                                      B-1

inquiries regarding and discussed the Merger and the Merger Agreement and other
matters related thereto with Company's counsel; and (viii) performed such other
analyses and examinations as we have deemed appropriate.

    In connection with our review, we have not assumed any obligation
independently to verify the foregoing information and have relied on its being
accurate and complete in all material respects. With respect to the financial
forecasts for Company provided to us by Company's management, upon their advice
and with your consent we have assumed for purposes of our opinion that the
forecasts have been reasonably prepared on bases reflecting the best available
estimates and judgments of Company's management at the time of preparation as to
the future financial performance of Company and that they provide a reasonable
basis upon which we can form our opinion. We have also assumed that there have
been no material changes in Company's or Parent's assets, financial condition,
results of operations, business or prospects since the respective dates of their
last financial statements made available to us, except to reflect changes which
were publicly disclosed by Parent. We have relied on advice of counsel and
independent accountants to Company as to all legal and financial reporting
matters with respect to Company, the Merger and the Merger Agreement. We have
assumed that the Merger will be consummated in a manner that complies in all
respects with the applicable provisions of the Securities Act of 1933, as
amended (the "Securities Act"), the Securities Exchange Act of 1934 and all
other applicable federal and state statutes, rules and regulations. In addition,
we have not assumed responsibility for making an independent evaluation,
appraisal or physical inspection of any of the assets or liabilities (contingent
or otherwise) of Company or Parent, nor have we been furnished with any such
appraisals. The Company management team has informed us, and we have assumed,
that the Merger will be recorded as a purchase under generally accepted
accounting principles. Finally, our opinion is based on economic, monetary and
market and other conditions as in effect on, and the information made available
to us as of, the date hereof. Since this opinion is being rendered during a
period of significant and uncommon volatility in the capital markets, it is
subject to the absence of further material changes in economic, monetary, market
and other conditions from those existing on the date hereof. Accordingly,
although subsequent developments may affect this opinion, we have not assumed
any obligation to update, revise or reaffirm this opinion.

    We have further assumed with your consent that the Merger will be
consummated in accordance with the terms described in the draft dated
September 20, 2001 of the Merger Agreement, without any further amendments
thereto, and without waiver by Company of any of the conditions to its
obligations thereunder.

    We have been engaged to render a fairness opinion with respect to the Merger
Consideration and will receive a fee for our services. In the ordinary course of
our business, we actively trade the equity securities of both Parent and Company
for our own account and for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities.

    Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Merger Consideration to be received by shareholders
of Company (other than Parent and Merger Sub) pursuant to the Merger is fair to
such shareholders from a financial point of view, as of the date hereof.

    This opinion is directed to the Board of Directors of Company in its
consideration of the Merger and is not a recommendation to any shareholder as to
how such shareholder should vote with respect to the Merger. Further, this
opinion addresses only the financial fairness of the Merger Consideration to the
shareholders of Company and does not address the relative merits of the Merger
and any alternatives to the Merger, Company's underlying decision to proceed
with or effect the Merger, or any other aspect of the Merger. This opinion may
not be used or referred to by Company, or quoted or disclosed to any person in
any manner, without our prior written consent, which consent is hereby given to
the inclusion of this opinion in the proxy statement/prospectus to be filed with
the Securities and

                                      B-2

Exchange Commission in connection with the Merger, provided that this opinion be
disclosed in its entirety in such proxy statement/prospectus and that any
description of or reference to us or summary of this opinion or related
valuation analyses be in form and substance acceptable to us and our legal
counsel. In furnishing this opinion, we do not admit that we are experts within

                                                                         ANNEX C

                             STOCK OPTION AGREEMENT

    STOCK OPTION AGREEMENT, dated as of September 21, 2001 (the "AGREEMENT"),
between General Electric Company, a New York corporation ("PARENT"), and
Imatron Inc., a New Jersey corporation (the "COMPANY").

                                    RECITALS

    A. Simultaneously with the execution and delivery of this Agreement, Parent,
Ruby Merger Corp., a newly formed New Jersey corporation and a direct wholly
owned subsidiary of Parent ("SUB"), and the Company are entering into the
Agreement and Plan of Merger, dated as of the date hereof (the "MERGER
AGREEMENT"), which provides for the merger of Sub with and into the Company (the
"Merger");

    B. As a condition to Parent's willingness to enter into the Merger
Agreement, Parent has requested that the Company grant to Parent an option to
purchase up to 19.9% of the authorized and unissued shares of Company Common
Stock, upon the terms and subject to the conditions hereof; and

    C. In order to induce Parent to enter into the Merger Agreement, the Company
has agreed to grant Parent the requested option.

    NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

    1.  THE OPTION; EXERCISE; ADJUSTMENTS.  The Company hereby grants to Parent
an irrevocable option (the "OPTION") to purchase from time to time up to a
number of shares equal to 19.9% of the authorized and issued shares of Common
Stock, no par value per share, of the Company (the "COMPANY COMMON STOCK")
outstanding at the time of the Stock Exercise Notice (as defined below), upon
the terms and subject to the conditions set forth herein (the "OPTIONED
SHARES"). Subject to the conditions set forth in Section 2, the Option may be
exercised by Parent in whole or from time to time in part, at any time following
the occurrence of a Triggering Event (as defined below) and prior to the
termination of the Option in accordance with Section 19. If Parent wishes to
exercise the Option, Parent shall send a written notice to the Company (the
"STOCK EXERCISE NOTICE") specifying the total number of Optioned Shares it
wishes to purchase and a date (not later than 20 business days and not earlier
than two business days from the date such notice is given) for the closing of
such purchase (the "CLOSING DATE"). Parent may revoke an exercise of the Option
at any time prior to the Closing Date by written notice to the Company. If any
change in the number of issued and outstanding shares of Company Common Stock by
reason of any stock dividend, stock split, split-up, recapitalization, merger or
other change in the corporate or capital structure of the Company, the number of
Optioned Shares subject to the Option and the Exercise Price (as hereinafter
defined) per Optioned Share shall be appropriately adjusted. In the event that
any additional shares of Company Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the preceding sentence
or pursuant to this Agreement), the number of Optioned Shares subject to the
Option shall be adjusted so that, after such issuance, it equals (but does not
exceed) 19.9% of the number of shares of Company Common Stock then issued and
outstanding and 19.9% of the voting power of shares of capital stock of the
Company then issued and outstanding, after reduction, to the extent necessary to
comply with the exception to the shareholder approval requirements of the Nasdaq
National Market ("NASDAQ") for any shares issued pursuant to the Option.

                                      C-1

    2.  CONDITIONS TO EXERCISE OF OPTION AND DELIVERY OF OPTIONED SHARES.

        (a) Parent's right to exercise the Option is subject to the following
    conditions:

           (i) Neither Parent nor Sub shall have breached any of its material
       obligations under the Merger Agreement;

           (ii) No preliminary or permanent injunction or other order issued by
       any federal or state court of competent jurisdiction in the United States
       invalidating the grant or prohibiting the exercise of the Option or the
       delivery of the Optioned Shares shall be in effect;

          (iii) All waiting periods under the HSR Act (as defined below) that
       are applicable to the exercise of the Option shall have expired or been
       terminated; and

           (iv) One or more of the following events (a "TRIGGERING EVENT") shall
       have occurred on or after the date hereof: (A) any person, corporation,
       partnership, limited liability company or other entity or group (such
       person, corporation, partnership, limited liability company or other
       entity or group, other than Parent or an affiliate of Parent, being
       referred to hereinafter, singularly or collectively, as a "PERSON"),
       acquires or becomes the beneficial owner of 20% or more of the
       outstanding shares of Company Common Stock; (B) any group is formed which
       beneficially owns 20% or more of the outstanding shares of Company Common
       Stock; (C) any Person shall have commenced a tender or exchange offer for

       all or substantially all the assets of the Company, or other similar
       business combination involving the Company; (D) the Company enters into,
       or announces that it proposes to enter into, an agreement, including,
       without limitation, an agreement in principle, providing for a merger or
       other business combination involving the Company or a "significant
       subsidiary" (as defined in Rule 1.02(w) of Regulation S-X as promulgated
       by the Securities and Exchange Commission (the "SEC")) of the Company or
       the acquisition of a substantial interest in, or a substantial portion of
       the assets, business or operations of, the Company or a significant
       subsidiary (other than the transactions contemplated by the Merger
       Agreement); (E) any Person is granted any option or right, conditional or
       otherwise, to acquire or otherwise become the beneficial owner of shares
       of Company Common Stock which, together with all shares of Company Common
       Stock beneficially owned by such Person, results or would result in such
       Person being the beneficial owner of 20% or more of the outstanding
       shares of Company Common Stock; or (F) there is a public announcement
       with respect to a plan or intention by the Company, other than Parent or
       its affiliates, to effect any of the foregoing transactions. For purposes
       of this subparagraph (iv), the terms "group" and "beneficial owner" shall
       be defined by reference to Section 13(d) of the Securities Exchange Act
       of 1934, as amended (the "EXCHANGE ACT"), and the rules and regulations
       promulgated thereunder.

        (b) Parent's obligation to purchase the Optioned Shares following the
    exercise of the Option, and the Company's obligation to deliver the Optioned
    Shares, are subject to the conditions that:

           (i) No preliminary or permanent injunction or other order issued by
       any federal or state court of competent jurisdiction in the United States
       prohibiting the delivery of the Optioned Shares shall be in effect;

           (ii) The purchase of the Optioned Shares will not violate
       Rule 10b-18 promulgated under the Exchange Act; and

          (iii) All waiting periods under the Hart-Scott-Rodino Antitrust
       Improvements Act of 1976, as amended (the "HSR ACT") applicable to the
       exercise of the Option shall have expired or been terminated.

                                      C-2

    3.  EXERCISE PRICE FOR OPTIONED SHARES.  At any Closing Date, the Company
will deliver to Parent a certificate or certificates representing the Optioned
Shares in the denominations designated by Parent in its Stock Exercise Notice

Optioned Share equal to $1.89 (the "EXERCISE PRICE"), payable in cash. Payment
made by Parent to the Company pursuant to this Agreement shall be made by wire
transfer of federal funds to a bank designated by the Company or a check payable
in immediately available funds. After payment of the Exercise Price for the
Optioned Shares covered by the Stock Exercise Notice, the Option shall be deemed
exercised to the extent of the Optioned Shares specified in the Stock Exercise
Notice as of the date such Stock Exercise Notice is given to the Company.

    4.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company represents

the Company and the consummation by it of the transactions contemplated hereby

rights; (c) except as otherwise required by the HSR Act and, except for filings
required under the blue sky laws of any states and routine filings and subject
to Section 7, the execution and delivery of this Agreement by the Company and
the consummation by it of the transactions contemplated hereby do not require
the consent, approval or authorization of, or filing with, any person or public
authority and will not violate or conflict with the Company's Certificate of
Incorporation, or Bylaws, or result in the acceleration or termination of, or
constitute a default under, any indenture, license, approval, agreement,
understanding or other instrument, or any statute, rule, regulation, judgment,
order or other restriction binding upon or applicable to the Company or any of
its subsidiaries or any of their respective properties or assets; (d) the

actions so that the restrictions on business combinations contained in the New
Jersey Corporation Takeover Bid Disclosure Law and the Business Corporation Act
of New Jersey will not apply with respect to or as a result of the transactions

    5.  REPRESENTATIONS AND WARRANTIES OF PARENT.  Parent represents and
warrants to the Company that (a) the execution and delivery of this Agreement by
Parent and the consummation by it of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of Parent and
this Agreement has been duly executed and delivered by Parent and constitutes a
valid and binding agreement of Parent; and (b) Parent is acquiring the Option
and, if and when it exercises the Option, will be acquiring the Optioned Shares
issuable upon the exercise thereof, for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), and will not sell or
otherwise dispose of the Optioned Shares except pursuant to an effective
registration statement under the Securities Act or a valid exemption from
registration under the Securities Act.

    6.  THE CLOSING.  Any closing hereunder shall take place on the Closing Date
specified by Parent in its Stock Exercise Notice pursuant to Section 1 at
10:00 A.M., local time, or the first business day thereafter on which all of the
conditions in Section 2 are met, at the principal executive office of the
Company, or at such other time and place as the parties hereto may agree.

    7.  FILINGS RELATED TO OPTIONED SHARES.  The Company will make such filings
with the SEC as are required by the Exchange Act, and will use its best efforts
to effect all necessary filings by the Company under the HSR Act and to have the
Optioned Shares approved for quotation on NASDAQ.

                                      C-3

    8.  REGISTRATION RIGHTS.  (a) If the Company effects any registration or
registrations of shares of Company Common Stock under the Securities Act for its
own account or for any other shareholder of the Company at any time after the
exercise of the Option (other than a registration on Form S-4, Form S-8 or any
successor forms), it will allow Parent to participate in such registration or
registrations with respect to any or all of the Optioned Shares acquired upon
the exercise of the Option; PROVIDED, HOWEVER, that any request of Parent
pursuant to this Section 8(a) shall be with respect to at least 20% of the
Optioned Shares and PROVIDED, FURTHER, that if the managing underwriters in such
offering advise the Company that, in their written opinion, the number of
Optioned Shares requested by Parent to be included in such registration exceeds
the number of shares of Company Common Stock which can be sold in such offering,
the Company may exclude from such registration all or a portion, as may be
appropriate, of the Optioned Shares requested for inclusion by Parent.

        (b) At any time after the exercise of the Option, upon the request of
    Parent, the Company will promptly file and use its best efforts to cause to
    be declared effective a registration statement under the Securities Act (and
    applicable Blue Sky statutes) with respect to any or all of the Optioned
    Shares acquired upon the exercise of the Option; PROVIDED, HOWEVER, that any
    request of Parent pursuant to this Section 8(b) shall be with respect to at
    least 20% of the Optioned Shares and PROVIDED, FURTHER, that the Company
    shall not be required to have declared effective more than two registration
    statements hereunder and shall be entitled to delay the effectiveness of
    each such registration statement, for a single period not to exceed 90 days
    during any 365 day period, if the commencement of such offering would, in
    the reasonable good faith judgment of the Board of Directors of the Company,
    require premature disclosure of any material corporate development or
    otherwise materially interfere with or materially adversely affect any
    pending or proposed offering of securities of the Company. In connection
    with any such registration requested by Parent, the costs of such
    registration (other than fees of Parent's counsel and underwriting fees and
    commissions) shall be borne by the Company, and the Company and Parent each
    shall provide the other and any underwriters with customary indemnification
    and contribution agreements.

    9.  OPTIONAL PUT; OPTIONAL REPURCHASE.

        (a) Prior to the termination of the Option in accordance with
    Section 19, if a Put Event has occurred, Parent shall have the right, upon
    three business days' prior written notice to the Company, to require the
    Company to purchase the Option from Parent (the "PUT RIGHT") at a cash
    purchase price (the "PUT PRICe") equal to the product determined by
    multiplying (A) the number of Optioned Shares as to which the Option has not
    yet been exercised by (B) the Spread (as defined below). As used herein,
    "PUT EVENT" means the occurrence on or after the date hereof of any of the
    following: (i) any Person (other than Parent or its affiliates) acquires or
    becomes the beneficial owner of 50% or more of the outstanding shares of
    Company Common Stock or (ii) the Company consummates a merger or other
    business combination involving the Company or a "significant subsidiary" (as
    defined in Rule 1.02(w) of Regulation S-X as promulgated by the SEC) of the
    Company or the acquisition of a substantial interest in, or a substantial
    portion of the assets, business or operations of, the Company or a
    significant subsidiary (other than the transactions contemplated by the
    Merger Agreement). As used herein, the term "SPREAD" shall mean the excess,
    if any, of (i) the greater of (x) the highest price (in cash or fair market
    value of securities or other property) per share of Company Common Stock
    paid or to be paid within 12 months preceding the date of exercise of the
    Put Right for any shares of Company Common Stock beneficially owned by any
    Person who shall have acquired or become the beneficial owner of 20% or more
    of the outstanding shares of Company Common Stock after the date hereof or
    (y) the average of the daily volume-weighted sales prices quoted on NASDAQ
    of the Company Common Stock during the five trading days immediately
    preceding the written notice of exercise of the Put Right over (ii) the
    Exercise Price.

                                      C-4

        (b) For a period of 90 days after the termination of the Option granted
    hereunder pursuant to Section 19, the Company shall have the right, upon
    three business days' prior written notice, to repurchase from Parent (the
    "Repurchase Right"), all (but not less than all) of the Optioned Shares
    acquired by the Parent hereby and with respect to which the Parent then has
    beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) at a
    price per share equal to the greater of (i) the average of the daily
    volume-weighted sales price quoted on NASDAQ of the Company Common Stock
    during the five trading days immediately preceding the written notice of
    exercise of the Repurchase Right and (ii) the Exercise Price, plus interest
    at a rate per annum equal to the costs of funds to Parent at the time of
    exercise of the Repurchase Right, subject to paragraph (c) below.

        (c) Parent shall deliver to the Company all "Excess Compensation"
    realized upon the sale of any Optioned Shares. "Excess Compensation" shall
    mean the amount, if any, by which the sum of (i) the aggregate gross
    proceeds received upon the sale of any Optioned Shares, and (ii) any
    Termination Fee paid by the Company under Section 5.6 of the Merger
    Agreement, exceeds the sum of (x) $11,000,000, (y) the aggregate Exercise
    Price paid, and (z) any underwriters discount or selling commission incurred
    by Parent in connection with the acquisition and disposition of the Optioned
    Shares.

    10.  EXPENSES.  Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise provided in Section 8 or as
specified in the Merger Agreement.

    11.  SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable damage

                             SHAREHOLDER AGREEMENT

    SHAREHOLDER AGREEMENT, dated as of September 21, 2001 (this "AGREEMENT"), by
the undersigned shareholders (collectively, the "SHAREHOLDERS") of
Imatron Inc., a New Jersey corporation (the "COMPANY"), for the benefit of
General Electric Company, a New York corporation ("PARENT").

                                    RECITALS

    A. Parent, Ruby Merger Corp., a New Jersey corporation and a direct wholly
owned subsidiary of Parent ("SUB"), and the Company are entering into the
Agreement and Plan of Merger, dated as of the date hereof (the "MERGER
AGREEMENT"), whereby, upon the terms and subject to the conditions set forth in
the Merger Agreement, each issued and outstanding share of Common Stock, no par
value per share, of the Company ("COMPANY COMMON STOCK"), not owned directly or
indirectly by Parent or the Company, will be converted into shares of Common
Stock, par value $.06 per share, of Parent ("PARENT COMMON STOCK");

    B.  As of the date hereof, each Shareholder owns that number of shares of
Company Common Stock appearing opposite his name on SCHEDULE A (such shares of
Company Common Stock together with any other shares of capital stock of the
Company acquired by such Shareholder, individually, after the date hereof during
the term of this Agreement, whether upon the exercise of options or by means of
purchase, dividend, distribution or otherwise, being collectively referred to
herein as the "SUBJECT SHARES"); and

    C.  As a condition to its willingness to enter into the Merger Agreement,
Parent has required that the Shareholders agree, and in order to induce Parent
to enter into the Merger Agreement the Shareholders have agreed, to enter into
this Agreement.

    NOW, THEREFORE, in consideration of the promises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

    1.  COVENANTS OF SHAREHOLDERS.  Until the termination of this Agreement in
accordance with Section 3, the Shareholders agree as follows:

        (a) The Shareholders shall attend the Shareholder Meeting, in person or
    by proxy, and at the Shareholder Meeting (or at any adjournment thereof) or
    in any other circumstances upon which a vote, consent or other approval with
    respect to the Merger and the Merger Agreement is sought, the Shareholders
    shall vote (or cause to be voted) the Subject Shares in favor of the Merger,
    the adoption of the Merger Agreement and the approval of the terms thereof
    and each of the other transactions contemplated by the Merger Agreement.

        (b) At any meeting of shareholders of the Company or at any adjournment
    thereof or in any other circumstances upon which the Shareholders' vote,
    consent or other approval is sought, the Shareholders shall vote (or cause
    to be voted) the Subject Shares against (i) any merger agreement or merger
    (other than the Merger Agreement and the Merger), consolidation,
    combination, sale of substantial assets, reorganization, recapitalization,
    dissolution, liquidation or winding up of or by the Company or any
    Subsidiary or any Takeover Proposal or (ii) any amendment of the Company's
    Amended and Restated Certificate of Incorporation, or By-laws or other
    proposal or transaction involving the Company or any of its Subsidiaries,
    which amendment or other proposal or transaction would in any manner impede,
    frustrate, prevent or nullify the Merger, the Merger Agreement or any of the
    other transactions contemplated by the Merger Agreement or change in any
    manner the voting rights of any class of capital stock of the Company. The
    Shareholders further agrees not to commit or agree to take any action
    inconsistent with the foregoing.

                                      D-1

        (c) The Shareholders agree not to (i) sell, transfer, pledge, assign or
    otherwise dispose of (including by gift) (collectively, "TRANSFER"), or
    enter into any contract, option or other arrangement (including any
    profit-sharing arrangement) with respect to the Transfer of the Subject
    Shares to any person or (ii) enter into any voting arrangement, whether by
    proxy, voting agreement or otherwise, in relation to the Subject Shares, and
    agree not to commit or agree to take any of the foregoing actions.

        (d) The Shareholders shall not, nor shall the Shareholders authorize any
    investment banker, attorney or other advisor or representative of the
    Shareholders to, directly or indirectly (i) solicit, initiate or encourage
    the submission of, any Takeover Proposal or (ii) participate in any
    discussions or negotiations regarding, or furnish to any person any
    information with respect to the Company or any Subsidiary in connection
    with, or take any other action to facilitate any inquiries or the making of
    any proposal that constitutes or may reasonably be expected to lead to, any
    Takeover Proposal.

        (e) The Shareholders shall use the Shareholders' reasonable best efforts
    to take, or cause to be taken, all actions, and to do, or cause to be done,
    and to assist and cooperate with Parent in doing, all things necessary,
    proper or advisable to support and to consummate and make effective, in the
    most expeditious manner practicable, the Merger and the other transactions
    contemplated by the Merger Agreement.

        (f) The Shareholders agree to promptly notify Parent in writing of the
    nature and amount of any acquisition by such Shareholder of any voting
    securities of the Company acquired by such Shareholder hereafter.

        (g) The Shareholders shall not knowingly take or fail to take any action
    which would cause any of the representations and warranties set forth in the
    Shareholder Tax Certificate attached hereto as SCHEDULE B to be untrue or
    incorrect.

        (h) The Shareholder hereby revokes any and all prior proxies or powers
    of attorney in respect of any of Subject Shares and constitutes and appoints
    Sub and Parent, or any nominee of Sub and Parent, or any of them, with full
    power of substitution and resubstitution, at any time during the term
    hereof, as its true and lawful attorney and proxy (its "Proxy"), for and in
    its name, place and stead (i) to demand that the Secretary of the Company
    call a special meeting of the shareholders of the Company for the purpose of
    considering any matter referred to in Section 1(a) and 1(b) hereof, (ii) to
    vote each of such Subject Shares as provided in Sections 1(a) and 1(b) as
    its proxy at every annual, special, adjourned or postponed meeting of the
    shareholders of the Company, including the right to sign its name (as
    shareholder) to any consent, certificate or other document relating to the
    Company that New Jersey Law may permit or require as provided in Sections
    1(a) and 1(b) and (iii) to approve any other motion or action in furtherance
    of the foregoing.

        THE FOREGOING PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED
    WITH AN INTEREST THROUGHOUT THE TERM OF THIS AGREEMENT.

    2.  REPRESENTATIONS AND WARRANTIES.  Each Shareholder represents and
warrants with respect to himself to Parent as follows:

        (a) The Shareholder is the record and beneficial owner of, and has good
    and marketable title to, the Subject Shares. The Shareholder does not own,
    of record or beneficially, any shares of capital stock of the Company other
    than the Subject Shares. The Shareholder has the sole right to vote, and the
    sole power of disposition with respect to, the Subject Shares, and none of
    the Subject Shares is subject to any voting trust, proxy or other agreement,
    arrangement or restriction with respect to the voting or disposition of such
    Subject Shares, except as contemplated by this Agreement.

                                      D-2

        (b) This Agreement has been duly executed and delivered by the
    Shareholder. Assuming the due authorization, execution and delivery of this
    Agreement by Parent, this Agreement constitutes the valid and binding
    agreement of the Shareholder enforceable against the Shareholder in
    accordance with its terms. The execution and delivery of this Agreement by
    the Shareholder does not and will not conflict with any agreement, order or
    other instrument binding upon the Shareholder, nor require any regulatory
    filing or approval, other than pursuant to the HSR Act (as defined below).

        (c) To the knowledge of the Shareholder, the representations set forth
    in the Shareholder Tax Certificate attached hereto as Schedule B, if made on
    the date hereof (assuming the Merger were consummated as of the date
    hereof), would be true and correct.

    3.  THE OPTION; EXERCISE; ADJUSTMENTS.  Each Shareholder hereby grants to
Parent an irrevocable option (the "OPTION") to purchase from time to time the
Subject Shares, upon the terms and subject to the conditions set forth herein
(the "OPTIONED SHARES"). Subject to the conditions set forth in Section 4, the
Option may be exercised by Parent in whole or from time to time in part, at any
time following the occurrence of a Triggering Event (as defined below) and prior
to the termination of the Option in accordance with Section 8. In the event
Parent wishes to exercise the Option, Parent shall send a written notice to the
applicable Shareholder (the "STOCK EXERCISE NOTICE") specifying the total number
of Optioned Shares it wishes to purchase and a date (not later than 20 business
days and not earlier than two business days from the date such notice is given)
for the closing of such purchase (the "CLOSING DATE"). Parent may revoke an
exercise of the Option at any time prior to the Closing Date by written notice
to the applicable Shareholder. In the event of any change in the number of
issued and outstanding shares of Subject Shares by reason of any stock dividend,
stock split, split-up, recapitalization, merger or other change in the corporate
or capital structure of the Company, the number of Optioned Shares subject to
the Option and the Exercise Price (as hereinafter defined) per Optioned Share
shall be appropriately adjusted.

    4.  CONDITIONS TO EXERCISE OF OPTION AND DELIVERY OF OPTIONED SHARES.

        (a) Parent's right to exercise the Option is subject to the following
    conditions:

           (i) Neither Parent nor Sub shall have breached any of its material
       obligations under the Merger Agreement;

           (ii) No preliminary or permanent injunction or other order issued by
       any federal or state court of competent jurisdiction in the United States
       invalidating the grant or prohibiting the exercise of the Option or the
       delivery of the Optioned Shares shall be in effect;

          (iii) All waiting periods under the HSR Act (as defined below)
       applicable to the exercise of the Option shall have expired or been
       terminated; and

           (iv) One or more of the following events shall have occurred on or
       after the date hereof: (A) any person, corporation, partnership, limited
       liability company or other entity or group (such person, corporation,
       partnership, limited liability company or other entity or group, other
       than Parent or an affiliate of Parent, being referred to hereinafter,
       singularly or collectively, as a "PERSON"), acquires or becomes the
       beneficial owner of 20% or more of the outstanding shares of Company
       Common Stock; (B) any group is formed which beneficially owns 20% or more
       of the outstanding shares of Company Common Stock; (C) any Person shall
       have commenced a tender or exchange offer for 20% or more of the then
       outstanding shares of Company Common Stock or publicly proposed any bona

       assets of the Company, or other similar business combination involving
       the Company; (D) the Company enters into, or announces that it proposes
       to enter into, an agreement, including, without limitation, an agreement
       in principle, providing for a merger or other business combination
       involving the Company or a "significant

                                      D-3

       subsidiary" (as defined in Rule 1.02(w) of Regulation S-X as promulgated
       by the Securities and Exchange Commission (the "SEC")) of the Company or
       the acquisition of a substantial interest in, or a substantial portion of
       the assets, business or operations of, the Company or a significant
       subsidiary (other than the transactions contemplated by the Merger
       Agreement); (E) any Person is granted any option or right, conditional or
       otherwise, to acquire or otherwise become the beneficial owner of shares
       of Company Common Stock which, together with all shares of Company Common
       Stock beneficially owned by such Person, results or would result in such
       Person being the beneficial owner of 20% or more of the outstanding
       shares of Company Common Stock; or (F) there is a public announcement
       with respect to a plan or intention by the Company, other than Parent or
       its affiliates, to effect any of the foregoing transactions. For purposes
       of this subparagraph (iii), the terms "group" and "beneficial owner"
       shall be defined by reference to Section 13(d) of the Securities Exchange
       Act of 1934, as amended (the "EXCHANGE ACT"), and the rules and
       regulations promulgated thereunder.

        (b) Parent's obligation to purchase the Optioned Shares following the
    exercise of the Option, and the Company's obligation to deliver the Optioned
    Shares, are subject to the conditions that:

       prohibiting the delivery of the Optioned Shares shall be in effect;

           (ii) The purchase of the Optioned Shares will not violate
       Rule 10b-18 promulgated under the Exchange Act; and

          (iii) All applicable waiting periods under the Hart-Scott-Rodino
       Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), shall
       have expired or been terminated.

    5.  EXERCISE PRICE FOR OPTIONED SHARES.  At any Closing Date, the applicable
Shareholder will deliver to Parent a certificate or certificates representing
the Optioned Shares in the denominations designated by Parent in its Stock
Exercise Notice and Parent will purchase the Optioned Shares from such
Shareholder at a price per Optioned Share equal to $1.89 (the "EXERCISE PRICE"),
payable in cash. Payment made by Parent to such Shareholder pursuant to this
Agreement shall be made by wire transfer of federal funds to a bank designated
by such Shareholder or a check payable in immediately available funds. After
payment of the Exercise Price for the Optioned Shares covered by the Stock
Exercise Notice, the Option shall be deemed exercised to the extent of the
Optioned Shares specified in the Stock Exercise Notice as of the date such Stock
Exercise Notice is given to such Shareholder.

    6.  REPRESENTATIONS AND WARRANTIES OF PARENT.  Parent represents and
warrants to the Company that (a) the execution and delivery of this Agreement by
Parent and the consummation by it of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of Parent and
this Agreement has been duly executed and delivered by Parent and constitutes a
valid and binding agreement of Parent; and (b) Parent is acquiring the Option
and, if and when it exercises the Option, will be acquiring the Optioned Shares
issuable upon the exercise thereof, for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), and will not sell or
otherwise dispose of the Optioned Shares except pursuant to an effective
registration statement under the Securities Act or a valid exemption from
registration under the Securities Act.

    7.  THE CLOSING.  Any closing hereunder shall take place on the Closing Date
specified by Parent in its Stock Exercise Notice pursuant to Section 3 at
10:00 A.M., local time, or the first business day thereafter on which all of the
conditions in Section 4 are met, at the principal executive office of the
Company, or at such other time and place as the parties hereto may agree.

                                      D-4

    8.  TERMINATION.  The obligations of the Shareholders hereunder shall
terminate upon the earlier to occur of (i) 6 months after the termination of the
Merger Agreement pursuant to Section 7.1 thereof and (ii) the Effective Time;
PROVIDED, HOWEVER, that if the Merger Agreement is terminated by the Company
pursuant to Section 7.1(b), (c) or (d) thereof (other than a termination
pursuant to Section 7.1(d)(i) following receipt of a Superior Proposal) or if
the Merger Agreement is terminated pursuant to Section 7.1(a) thereof, then such
obligations shall terminate upon the termination of the Merger Agreement. No
such termination of this Agreement shall relieve any party hereto from any
liability for any breach of this Agreement prior to termination.

    9.  WAIVER OF REGISTRATION RIGHTS.  The Shareholders hereby waive,
relinquish and forego any and all registration rights and or obligations of the
Company, Parent, the Surviving Corporation, or any of their respective
affiliates to register any equity securities of the Company or any equity
securities of Parent received in exchange for securities of the Company.

    10.  FURTHER ASSURANCES.  The Shareholders will, from time to time, execute
and deliver, or cause to be executed and delivered, such additional or further
consents, documents and other instruments as Parent may reasonably request for
the purpose of effectively carrying out the transactions contemplated by this
Agreement.

    11.  SUCCESSORS, ASSIGNS AND TRANSFEREES BOUND.  Any successor, assignee or
transferee (including a successor, assignee or transferee as a result of the
death of the Shareholder, such as an executor or heir) shall be bound by the
terms hereof, and the Shareholders shall take any and all actions necessary to
obtain the written confirmation from such successor, assignee or transferee that
it is bound by the terms hereof.

    12.  AFFILIATE LETTER; SHAREHOLDER TAX CERTIFICATE.  The Shareholders agree
to execute and deliver on a timely basis, when and if requested by Parent, (i) a
written agreement in substantially the form of Exhibit E to the Merger Agreement
and (ii) the Shareholder Tax Certificate attached hereto as SCHEDULE B.

    13.  REMEDIES.  The Shareholders acknowledge that money damages would be
both incalculable and an insufficient remedy for any breach of this Agreement by
it, and that any such breach would cause Parent irreparable harm. Accordingly,
the Shareholders agree that in the event of any breach or threatened breach of
this Agreement, Parent, in addition to any other remedies at law or in equity it
may have, shall be entitled, without the requirement of posting a bond or other
security, to equitable relief, including injunctive relief and specific
performance.

    14.  SEVERABILITY.  The invalidity or unenforceability of any provision of
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

    15.  AMENDMENT.  This Agreement may be amended only by means of a written
instrument executed and delivered by both the Shareholders and Parent.

    16.  JURISDICTION.  Each party hereby irrevocably submits to the exclusive
jurisdiction of the U.S. District Court for the Southern District of New York in
any action, suit or proceeding arising in connection with this Agreement, and
agrees that any such action, suit or proceeding shall be brought only in such
courts (and waives any objection based on FORUM NON CONVENIENS or any other
objection to venue therein). Each party hereto waives any right to a trial by
jury in connection with any such action, suit or proceeding.

    17.  GOVERNING LAW.  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

                             SHAREHOLDER AGREEMENT

    SHAREHOLDER AGREEMENT, dated as of September 21, 2001 (this "AGREEMENT"), by
the undersigned shareholders (collectively, the "SHAREHOLDERS") of
Imatron, Inc., a New Jersey corporation (the "COMPANY"), for the benefit of
General Electric Company, a New York corporation ("PARENT").

                                    RECITALS

    A. Parent, Ruby Merger Corp., a New Jersey corporation and a direct wholly
owned subsidiary of Parent ("SUB"), and the Company are entering into the
Agreement and Plan of Merger, dated as of the date hereof (the "MERGER
AGREEMENT"), whereby, upon the terms and subject to the conditions set forth in
the Merger Agreement, each issued and outstanding share of Common Stock, no par
value per share, of the Company ("COMPANY COMMON STOCK"), not owned directly or
indirectly by Parent or the Company, will be converted into shares of Common
Stock, par value $.06 per share, of Parent ("PARENT COMMON STOCK");

    B.  As of the date hereof, each Shareholder owns that number of shares of
Company Common Stock appearing opposite his name on SCHEDULE A (a number of
shares equal to 70% of (i) such shares of Company Common Stock, and (ii) any
other shares of capital stock of the Company acquired by such Shareholder after
the date hereof during the term of this Agreement, whether upon the exercise of
options or warrants or by means of purchase, dividend, distribution or
otherwise, being collectively referred to herein as the "SUBJECT SHARES"); and

    C.  As a condition to its willingness to enter into the Merger Agreement,
Parent has required that the Shareholders agree, and in order to induce Parent
to enter into the Merger Agreement the Shareholders have agreed, to enter into
this Agreement.

    NOW, THEREFORE, in consideration of the promises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

    1.  COVENANTS OF SHAREHOLDERS.  Until the termination of this Agreement in
accordance with Section 8, the Shareholders agree as follows:

        (a) The Shareholders shall attend the Shareholder Meeting, in person or
    by proxy, and at the Shareholder Meeting (or at any adjournment thereof) or
    in any other circumstances upon which a vote, consent or other approval with
    respect to the Merger and the Merger Agreement is sought, the Shareholders
    shall vote (or cause to be voted) the Subject Shares in favor of the Merger,
    the adoption of the Merger Agreement and the approval of the terms thereof
    and each of the other transactions contemplated by the Merger Agreement.

        (b) At any meeting of shareholders of the Company or at any adjournment
    thereof or in any other circumstances upon which the Shareholders' vote,
    consent or other approval is sought, the Shareholders shall vote (or cause
    to be voted) the Subject Shares against (i) any merger agreement or merger
    (other than the Merger Agreement and the Merger), consolidation,
    combination, sale of substantial assets, reorganization, recapitalization,
    dissolution, liquidation or winding up of or by the Company or any
    Subsidiary or any Takeover Proposal or (ii) any amendment of the Company's
    Amended and Restated Certificate of Incorporation, or By-laws or other
    proposal or transaction involving the Company or any of its Subsidiaries,
    which amendment or other proposal or transaction would in any manner impede,
    frustrate, prevent or nullify the Merger, the Merger Agreement or any of the
    other transactions contemplated by the Merger Agreement or change in any
    manner the voting rights of any class of capital stock of the Company. The
    Shareholders further agrees not to commit or agree to take any action
    inconsistent with the foregoing.

                                      E-1

        (c) The Shareholders agree not to (i) sell, transfer, pledge, assign or
    otherwise dispose of (including by gift) (collectively, "TRANSFER"), or
    enter into any contract, option or other arrangement (including any
    profit-sharing arrangement) with respect to the Transfer of the Subject
    Shares to any person or (ii) enter into any voting arrangement, whether by
    proxy, voting agreement or otherwise, in relation to the Subject Shares, and
    agree not to commit or agree to take any of the foregoing actions.

        (d) The Shareholders shall not, nor shall the Shareholders authorize any
    investment banker, attorney or other advisor or representative of the
    Shareholders to, directly or indirectly (i) solicit, initiate or encourage
    the submission of, any Takeover Proposal or (ii) participate in any
    discussions or negotiations regarding, or furnish to any person any
    information with respect to the Company or any Subsidiary in connection
    with, or take any other action to facilitate any inquiries or the making of
    any proposal that constitutes or may reasonably be expected to lead to, any
    Takeover Proposal.

        (e) The Shareholders shall use the Shareholders' reasonable best efforts
    to take, or cause to be taken, all actions, and to do, or cause to be done,
    and to assist and cooperate with Parent in doing, all things necessary,
    proper or advisable to support and to consummate and make effective, in the
    most expeditious manner practicable, the Merger and the other transactions
    contemplated by the Merger Agreement.

        (f) The Shareholders agree to promptly notify Parent in writing of the
    nature and amount of any acquisition by such Shareholder of any voting
    securities of the Company acquired by such Shareholder hereafter.

        (g) The Shareholders shall not knowingly take or fail to take any action
    which would cause any of the representations and warranties set forth in the
    Shareholder Tax Certificate attached hereto as SCHEDULE B to be untrue or
    incorrect.

        (h) The Shareholder hereby revokes any and all prior proxies or powers
    of attorney in respect of any of Subject Shares and constitutes and appoints
    Sub and Parent, or any nominee of Sub and Parent, or any of them, with full
    power of substitution and resubstitution, at any time during the term
    hereof, as its true and lawful attorney and proxy (its "Proxy"), for and in
    its name, place and stead (i) to demand that the Secretary of the Company
    call a special meeting of the shareholders of the Company for the purpose of
    considering any matter referred to in Section 1(a) and 1(b) hereof, (ii) to
    vote each of such Subject Shares as provided in Sections 1(a) and 1(b) as
    its proxy at every annual, special, adjourned or postponed meeting of the
    shareholders of the Company, including the right to sign its name (as
    shareholder) to any consent, certificate or other document relating to the
    Company that New Jersey Law may permit or require as provided in Sections
    1(a) and 1(b) and (iii) to approve any other motion or action in furtherance
    of the foregoing.

        THE FOREGOING PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED
    WITH AN INTEREST THROUGHOUT THE TERM OF THIS AGREEMENT.

    2.  REPRESENTATIONS AND WARRANTIES.  Each Shareholder represents and
warrants with respect to himself to Parent as follows:

        (a) The Shareholder is the record and beneficial owner of, and has good
    and marketable title to, the Subject Shares. The Shareholder does not own,
    of record or beneficially, any shares of capital stock of the Company other
    than the Subject Shares. The Shareholder has the sole right to vote, and the
    sole power of disposition with respect to, the Subject Shares, and none of
    the Subject Shares is subject to any voting trust, proxy or other agreement,
    arrangement or restriction with respect to the voting or disposition of such
    Subject Shares, except as contemplated by this Agreement.

                                      E-2

        (b) This Agreement has been duly executed and delivered by the
    Shareholder. Assuming the due authorization, execution and delivery of this
    Agreement by Parent, this Agreement constitutes the valid and binding
    agreement of the Shareholder enforceable against the Shareholder in
    accordance with its terms. The execution and delivery of this Agreement by
    the Shareholder does not and will not conflict with any agreement, order or
    other instrument binding upon the Shareholder, nor require any regulatory
    filing or approval, other than pursuant to the HSR Act (as defined below).

        (c) To the knowledge of the Shareholder, the representations set forth
    in the Shareholder Tax Certificate attached hereto as Schedule B, if made on
    the date hereof (assuming the Merger were consummated as of the date
    hereof), would be true and correct.

    3.  THE OPTION; EXERCISE; ADJUSTMENTS.  Each Shareholder hereby grants to
Parent an irrevocable option (the "OPTION") to purchase from time to time the
Subject Shares, upon the terms and subject to the conditions set forth herein
(the "OPTIONED SHARES"). Subject to the conditions set forth in Section 4, the
Option may be exercised by Parent in whole or from time to time in part, at any
time following the occurrence of a Triggering Event (as defined below) and prior
to the termination of the Option in accordance with Section 8. In the event
Parent wishes to exercise the Option, Parent shall send a written notice to the
applicable Shareholder (the "STOCK EXERCISE NOTICE") specifying the total number
of Optioned Shares it wishes to purchase and a date (not later than 20 business
days and not earlier than two business days from the date such notice is given)
for the closing of such purchase (the "CLOSING DATE"). Parent may revoke an
exercise of the Option at any time prior to the Closing Date by written notice
to the applicable Shareholder. In the event of any change in the number of
issued and outstanding shares of Subject Shares by reason of any stock dividend,
stock split, split-up, recapitalization, merger or other change in the corporate
or capital structure of the Company, the number of Optioned Shares subject to
the Option and the Exercise Price (as hereinafter defined) per Optioned Share
shall be appropriately adjusted.

    4.  CONDITIONS TO EXERCISE OF OPTION AND DELIVERY OF OPTIONED SHARES.

        (a) Parent's right to exercise the Option is subject to the following
    conditions:

           (i) Neither Parent nor Sub shall have breached any of its material
       obligations under the Merger Agreement;

           (ii) No preliminary or permanent injunction or other order issued by
       any federal or state court of competent jurisdiction in the United States
       invalidating the grant or prohibiting the exercise of the Option or the
       delivery of the Optioned Shares shall be in effect;

          (iii) All waiting periods under the HSR Act (as defined below)
       applicable to the exercise of the Option shall have expired or been
       terminated; and

           (iv) One or more of the following events shall have occurred on or
       after the date hereof: (A) any person, corporation, partnership, limited
       liability company or other entity or group (such person, corporation,
       partnership, limited liability company or other entity or group, other
       than Parent or an affiliate of Parent, being referred to hereinafter,
       singularly or collectively, as a "PERSON"), acquires or becomes the
       beneficial owner of 20% or more of the outstanding shares of Company
       Common Stock; (B) any group is formed which beneficially owns 20% or more
       of the outstanding shares of Company Common Stock; (C) any Person shall
       have commenced a tender or exchange offer for 20% or more of the then
       outstanding shares of Company Common Stock or publicly proposed any bona

       assets of the Company, or other similar business combination involving
       the Company; (D) the Company enters into, or announces that it proposes
       to enter into, an agreement, including, without limitation, an agreement
       in principle, providing for a merger or other business combination
       involving the Company or a "significant

                                      E-3

       subsidiary" (as defined in Rule 1.02(w) of Regulation S-X as promulgated
       by the Securities and Exchange Commission (the "SEC")) of the Company or
       the acquisition of a substantial interest in, or a substantial portion of
       the assets, business or operations of, the Company or a significant
       subsidiary (other than the transactions contemplated by the Merger
       Agreement); (E) any Person is granted any option or right, conditional or
       otherwise, to acquire or otherwise become the beneficial owner of shares
       of Company Common Stock which, together with all shares of Company Common
       Stock beneficially owned by such Person, results or would result in such
       Person being the beneficial owner of 20% or more of the outstanding
       shares of Company Common Stock; or (F) there is a public announcement
       with respect to a plan or intention by the Company, other than Parent or
       its affiliates, to effect any of the foregoing transactions. For purposes
       of this subparagraph (iii), the terms "group" and "beneficial owner"
       shall be defined by reference to Section 13(d) of the Securities Exchange
       Act of 1934, as amended (the "EXCHANGE ACT"), and the rules and
       regulations promulgated thereunder.

        (b) Parent's obligation to purchase the Optioned Shares following the
    exercise of the Option, and the Company's obligation to deliver the Optioned
    Shares, are subject to the conditions that:

       prohibiting the delivery of the Optioned Shares shall be in effect;

           (ii) The purchase of the Optioned Shares will not violate
       Rule 10b-18 promulgated under the Exchange Act; and

          (iii) All applicable waiting periods under the Hart-Scott-Rodino
       Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), shall
       have expired or been terminated.

    5.  EXERCISE PRICE FOR OPTIONED SHARES.  At any Closing Date, the applicable
Shareholder will deliver to Parent a certificate or certificates representing
the Optioned Shares in the denominations designated by Parent in its Stock
Exercise Notice and Parent will purchase the Optioned Shares from such
Shareholder at a price per Optioned Share equal to $1.89 (the "EXERCISE PRICE"),
payable in cash. Payment made by Parent to such Shareholder pursuant to this
Agreement shall be made by wire transfer of federal funds to a bank designated
by such Shareholder or a check payable in immediately available funds. After
payment of the Exercise Price for the Optioned Shares covered by the Stock
Exercise Notice, the Option shall be deemed exercised to the extent of the
Optioned Shares specified in the Stock Exercise Notice as of the date such Stock
Exercise Notice is given to such Shareholder.

    6.  REPRESENTATIONS AND WARRANTIES OF PARENT.  Parent represents and
warrants to the Company that (a) the execution and delivery of this Agreement by
Parent and the consummation by it of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of Parent and
this Agreement has been duly executed and delivered by Parent and constitutes a
valid and binding agreement of Parent; and (b) Parent is acquiring the Option
and, if and when it exercises the Option, will be acquiring the Optioned Shares
issuable upon the exercise thereof, for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), and will not sell or
otherwise dispose of the Optioned Shares except pursuant to an effective
registration statement under the Securities Act or a valid exemption from
registration under the Securities Act.

    7.  THE CLOSING.  Any closing hereunder shall take place on the Closing Date
specified by Parent in its Stock Exercise Notice pursuant to Section 3 at
10:00 A.M., local time, or the first business day thereafter on which all of the
conditions in Section 4 are met, at the principal executive office of the
Company, or at such other time and place as the parties hereto may agree.

                                      E-4

    8.  TERMINATION.  The obligations of the Shareholders hereunder shall
terminate upon the earlier to occur of (i) 60 days after the termination of the
Merger Agreement pursuant to Section 7.1 thereof and (ii) the Effective Time;
PROVIDED, HOWEVER, that if the Merger Agreement is terminated by the Company
pursuant to Section 7.1(b), (c) or (d) thereof (other than a termination
pursuant to Section 7.1(d)(i) following receipt of a Superior Proposal) or if
the Merger Agreement is terminated pursuant to Section 7.1(a) thereof, then such
obligations shall terminate upon the termination of the Merger Agreement. No
such termination of this Agreement shall relieve any party hereto from any
liability for any breach of this Agreement prior to termination.

    9.  WAIVER OF REGISTRATION RIGHTS.  The Shareholders hereby waive,
relinquish and forego any and all registration rights and or obligations of the
Company, Parent, the Surviving Corporation, or any of their respective
affiliates to register any equity securities of the Company or any equity
securities of Parent received in exchange for securities of the Company.

    10.  FURTHER ASSURANCES.  The Shareholders will, from time to time, execute
and deliver, or cause to be executed and delivered, such additional or further
consents, documents and other instruments as Parent may reasonably request for
the purpose of effectively carrying out the transactions contemplated by this
Agreement.

    11.  SUCCESSORS, ASSIGNS AND TRANSFEREES BOUND.  Any successor, assignee or
transferee (including a successor, assignee or transferee as a result of the
death of the Shareholder, such as an executor or heir) shall be bound by the
terms hereof, and the Shareholders shall take any and all actions necessary to
obtain the written confirmation from such successor, assignee or transferee that
it is bound by the terms hereof.

    12.  AFFILIATE LETTER; SHAREHOLDER TAX CERTIFICATE.  The Shareholders agree
to execute and deliver on a timely basis, when and if requested by Parent, (i) a
written agreement in substantially the form of Exhibit E to the Merger Agreement
and (ii) the Shareholder Tax Certificate attached hereto as SCHEDULE B.

    13.  REMEDIES.  The Shareholders acknowledge that money damages would be
both incalculable and an insufficient remedy for any breach of this Agreement by
it, and that any such breach would cause Parent irreparable harm. Accordingly,
the Shareholders agree that in the event of any breach or threatened breach of
this Agreement, Parent, in addition to any other remedies at law or in equity it
may have, shall be entitled, without the requirement of posting a bond or other
security, to equitable relief, including injunctive relief and specific
performance.

    14.  SEVERABILITY.  The invalidity or unenforceability of any provision of
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

    15.  AMENDMENT.  This Agreement may be amended only by means of a written
instrument executed and delivered by both the Shareholders and Parent.

    16.  JURISDICTION.  Each party hereby irrevocably submits to the exclusive
jurisdiction of the U.S. District Court for the Southern District of New York in
any action, suit or proceeding arising in connection with this Agreement, and
agrees that any such action, suit or proceeding shall be brought only in such
courts (and waives any objection based on FORUM NON CONVENIENS or any other
objection to venue therein). Each party hereto waives any right to a trial by
jury in connection with any such action, suit or proceeding.

    17.  GOVERNING LAW.  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

                                      E-5

    18.  EXPENSES.  Each party hereto shall pay its own expenses incurred in

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 721 of the New York Business Corporation Law ("NYBCL") provides
that, in addition to indemnification provided in Article 7 of the NYBCL, a
corporation may indemnify a director or officer by a provision contained in the
certificate of incorporation or bylaws or by a duly authorized resolution of its
stockholders or directors or by agreement, PROVIDED that no indemnification may
be made to or on behalf of any director or officer if a judgment or other final
adjudication adverse to the director or officer establishes that his acts were
committed in bad faith or were the result of active and deliberate dishonesty
and were material to the cause of action so adjudicated, or that he personally
gained in fact a financial profit or other advantage to which he was not legally
entitled.

    Section 722(a) of the NYBCL provides that a corporation may indemnify a
director or officer made, or threatened to be made, a party to any action other
than a derivative action, whether civil or criminal, against judgments, fines,
amounts paid in settlement and reasonable expenses actually and necessarily
incurred as a result of such action, if such director or officer acted, in good
faith, for a purpose which he reasonably believed to be in, or not opposed to,
the best interests of the corporation and, in criminal actions or proceedings,
in addition, had no reasonable cause to believe that his conduct was unlawful.

    Section 722(c) of the NYBCL provides that a corporation may indemnify a
director or officer, made or threatened to be made a party in a derivative
action, against amounts paid in settlement and reasonable expenses actually and
necessarily incurred by him in connection with the defense or settlement of such
action, or in connection with an appeal therein if such director or officer
acted, in good faith, for a purpose which he reasonably believed to be in, or
not opposed to, the best interests of the corporation, except that no
indemnification will be available under Section 722(c) of the NYBCL in respect
of (1) a threatened or pending action which is settled or otherwise disposed of,
or (2) any claim as to which such director or officer shall have been adjudged
liable to the corporation, unless and only to the extent that the court in which
the action was brought, or, if no action was brought, any court of competent
jurisdiction, determines upon application, that, in view of all the
circumstances of the case, the director or officer is fairly and reasonably
entitled to indemnity for such portion of the settlement amount and expenses as
the court deems proper.

    Section 723 of the NYBCL specifies the manner in which payment of
indemnification under Section 722 of the NYBCL or indemnification permitted
under Section 721 of the NYBCL may be authorized by the corporation. It provides
that indemnification by a corporation is mandatory in any case in which the
director or officer has been successful, whether on the merits or otherwise, in
defending an action. In the event that the director or officer has not been
successful or the action is settled, indemnification must be authorized by the
appropriate corporate action as set forth in Section 723.

    Section 724 of the NYBCL provides that, upon application by a director or
officer, indemnification may be awarded by a court to the extent authorized
under Section 722 and Section 723 of the NYBCL. Section 725 of the NYBCL
contains certain other miscellaneous provisions affecting the indemnification of
directors and officers.

    Section 726 of the NYBCL authorizes a corporation to purchase and maintain
insurance to indemnify (1) a corporation for any obligation which it incurs as a
result of the indemnification of directors and officers under the provisions of
Article 7 of the NYBCL, (2) directors and officers in instances in which they
may be indemnified by a corporation under the provisions of Article 7 of the
NYBCL, and (3) directors and officers in instances in which they may not
otherwise be indemnified by a corporation under such section, provided the
contract of insurance covering such directors and

                                      II-1

officers provides, in a manner acceptable to the New York State Superintendent
of Insurance, for a retention amount and for co-insurance.

    Section 6 of the Restated Certificate of Incorporation, as amended, of GE
provides in part as follows:

           A person who is or was a director of the corporation shall have no
       personal liability to the corporation or its stockholders for damages for
       any breach of duty in such capacity except that the foregoing shall not
       eliminate or limit liability where such liability is imposed under the
       Business Corporation Law of the State of New York.

           Article XI of the bylaws, as amended, of GE provides, in part, as
       follows:

           The Company shall, to the fullest extent permitted by applicable law
       as the same exists or may hereafter be in effect, indemnify any person
       who is or was or has agreed to become a director or officer of the
       Company and who is or was made or threatened to be made a party to or is
       involved in any threatened, pending or completed action, suit or
       proceeding, whether civil, criminal, administrative or investigative,
       including an action by or in the right of the Company to procure a
       judgment in its favor and an action by or in the right of any other
       corporation of any type or kind, domestic or foreign, or any partnership,
       joint venture, trust, employee benefit plan or other enterprise, which
       such person is serving, has served or has agreed to serve in any capacity
       at the request of the Company, by reason of the fact that he or she is or
       was or has agreed to become a director or officer of the Company, or is
       or was serving or has agreed to serve such other corporation,
       partnership, joint venture, trust, employee benefit plan or other
       enterprise in any capacity, against judgments, fines, amounts paid or to
       be paid in settlement, taxes or penalties, and costs, charges and
       expenses, including attorney's fees, incurred in connection with such
       action or proceeding or any appeal therein, PROVIDED, HOWEVER, that no
       indemnification shall be provided to any such person if a judgment or
       other final adjudication adverse to the director or officer establishes
       that (i) his or her acts were committed in bad faith or were the result
       of active and deliberate dishonesty and, in either case, were material to
       the cause of action so adjudicated, or (ii) he or she personally gained
       in fact a financial profit or other advantage to which he or she was not
       legally entitled. The benefits of this Paragraph A shall extend to the
       heirs and legal representatives of any person entitled to indemnification
       under this paragraph.

           GE has purchased liability insurance for its officers and directors
       as permitted by Section 727 of the NYBCL.

ITEM 22.  UNDERTAKINGS.

    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.

    The undersigned registrant undertakes as follows: that any public reoffering
of the securities registered hereunder through use of a prospectus which is part
of this registration statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

    The registrant undertakes that every prospectus: (i) that is filed pursuant
to paragraph (1) immediately preceding, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and

                                      II-3

that for purposes of determining any liability under the Securities Act of 1933,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

Registrant has duly caused this Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Fairfield,
