*Estimated for purposes of calculating the amount of the filing fee only. The
fee was calculated on a transaction valuation determined by (i) multiplying
$6.8426, the per share tender offer price for shares of Common Stock, by
12,572,038, the number of currently outstanding shares of Common Stock sought
in the Offer (including 2,714,347 shares of Common Stock issuable upon the
exercise or conversion of outstanding stock options and warrants), which
gives an aggregate consideration of $86,025,427.22 (the "Common Stock
Consideration"), and (ii) multiplying $13.6852, the per share tender offer
price for shares of Preferred Stock, by 1,114,485, the number of currently
outstanding shares of Series A Convertible Preferred Stock sought



in the Offer, which gives an aggregate consideration of $15,251,950.12 for such
Preferred Stock, and adding the amount determined by (i) and (ii) together.

**Calculated at the rate of $92.00 per $1 million.

     This Amendment No. 1 (the "Amendment") amends and supplements Items 2,
4, 6, 7, 11 and 12 of the Tender Offer Statement on Schedule TO (the
"Schedule TO") originally filed on May 30, 2002, by Broadway Acquisition
Corp., a Delaware corporation ("Purchaser"), and Boston Scientific
Corporation, a Delaware corporation ("Parent"), relating to the offer by
Purchaser to purchase all of the outstanding shares of common stock, par
value $0.001 per share, including the associated preferred share purchase
rights, and all of the outstanding shares of Series A Convertible Preferred
Stock, par value $0.001 per share (together, the "Shares"), of BEI Medical
Systems Company, Inc., a Delaware corporation ("BEI"), at a purchase price of
$6.8426 per share of Common Stock and $13.6852 per share of Preferred Stock,
net to the seller in cash, upon the terms and subject to the conditions set
forth in the Offer to Purchase dated May 30, 2002 (the "Offer to Purchase"),
and in the related Letter of Transmittal (which, together with the Offer to
Purchase and any amendments or supplements hereto and thereto, collectively
constitute the "Offer"), copies of which were filed as Exhibits (a)(1)(i) and
(ii), respectively, to the Schedule TO. The information set forth in the
Offer to Purchase and the related Letter of Transmittal was incorporated into
the Schedule TO by reference with respect to Items 1-9 and 11 of the Schedule
TO. The Agreement and Plan of Merger, dated as of May 13, 2002 (the "Merger
Agreement"), among Parent, Purchaser and BEI, a copy of which was attached as
Exhibit (d)(i) to the Schedule TO, was incorporated in the Schedule TO by
reference with respect to Items 5 and 11 of the Schedule TO.

ITEM 2. SUBJECT COMPANY INFORMATION.

1.  Item 2 of the Schedule TO is hereby amended and supplemented by deleting in
    its entirety the second sentence of the first paragraph of Section 7 of the
    Offer to Purchase on page 12 thereof, which had previously been incorporated
    by reference into the Schedule TO, and replacing it with the following
    sentence:

                  "The accuracy and completeness of such information has not
                  been independently verified by Parent or Purchaser and Parent
                  and Purchaser may be unaware of events that have not been
                  disclosed by BEI that may affect the significance or accuracy
                  of any such information."

ITEM 4. TERMS OF THE TRANSACTION.

1.  Item 4(a) of the Schedule TO is hereby amended and supplemented by deleting
    the phrase "the acceptance of Shares for payment pursuant to the Offer" in
    the first line of the first paragraph on page 5 of the Offer to Purchase,
    which had previously been incorporated by reference into the Schedule TO,
    and replacing it with the following:

                  "the Expiration Date, provided that the Offer has not been
                  terminated prior to such date pursuant to the terms of the
                  Offer."

2.  Item 4(a) of the Schedule TO is hereby further amended and supplemented by
    deleting the reference to the Public Relations Newswire in the second
    paragraph on page 5 of the Offer to Purchase which had previously been

3.  Item 4(a) of the Schedule TO is hereby further amended and supplemented by

    paragraph on page 5 of the Offer to Purchase, which had previously been
    incorporated by reference into the Schedule TO:

                  "and such press release shall be filed with the Commission in
                  compliance with Rule 14d-4(d)(1) under the Exchange Act."

4.  Item 4(a) of the Schedule TO is hereby amended and supplemented by deleting
    in their entirety the second and third sentence of the first paragraph of
    Section 2 of the Offer to Purchase on page 6 thereof, which had previously
    been incorporated by reference into the Schedule TO, and replacing them with
    the two sentences:

                                       3


                  "Purchaser shall pay for all Shares validly tendered and not
                  withdrawn promptly following the Expiration Date, provided,
                  that the Offer has not been terminated pursuant to the terms
                  of the Offer prior to such date. Notwithstanding the
                  immediately preceding sentence and subject to applicable rules
                  and regulations of the Commission and the terms of the Merger
                  Agreement, Purchaser expressly reserves the right to delay
                  payment for Shares in the event that governmental approvals
                  are required to make such payments and such approvals have not
                  yet been obtained."

5.  Item 4(a) of the Schedule TO is hereby further amended and supplemented by
    deleting in its entirety the first sentence of the second paragraph of
    Section 5 of the Offer to Purchase on page 10 of the Offer to Purchase,
    which had previously been incorporated by reference into the Schedule TO.

6.  Item 4(a) of the Schedule TO is hereby further amended and supplemented by
    deleting the parenthetical "(including any action or inaction by Parent or
    any of its affiliates)" in the last paragraph of Section 14 of the Offer to
    Purchase on page 32 thereof, which had previously been incorporated by
    reference into the Schedule TO, and by adding the following clause at the
    end of the first sentence of such paragraph:

                  "prior to the expiration of the Offer."

ITEM 6. PURPOSES OF THE TRANSACTION AND PLANS OR PROPOSALS.

1.  Item 6 of the Schedule TO is hereby amended and supplemented by deleting the
    second paragraph in the section of the Offer to Purchase entitled "Appraisal
    Rights" on page 28 thereof, which had previously been incorporated by
    reference into the Schedule TO, and replacing it with the following
    paragraphs:

                  "Each stockholder electing to demand the appraisal of their
                  Shares shall deliver to BEI, before the taking of the vote on
                  the Merger, a written demand for appraisal of such Shares. A
                  proxy or vote against the merger or consolidation shall not
                  constitute such a demand. Within 10 days after the effective
                  date of the Merger, the Surviving Corporation will notify each
                  stockholder of BEI who has complied with the demand for
                  appraisal procedures and has not voted in favor of, or
                  consented to, the Merger as of the date that the Merger has
                  become effective.

                  Additionally, within 120 days after the effective date of the
                  Merger, any stockholder who is entitled to appraisal rights
                  may file a petition in the Delaware Court of Chancery
                  demanding a determination of the value of their Shares.

                  At the hearing on such petition, the Court of Chancery shall
                  (i) determine the stockholders who have complied with the
                  provisions of Section 262, and who have become entitled to
                  appraisal rights, and (ii) appraise the Shares, determining
                  their fair value exclusive of any element of value arising
                  from the accomplishment or expectation of the Merger, together
                  with a fair rate of interest, if any, to be paid upon the
                  amount determined to be the fair value. In determining such
                  fair value, the Court is required to take into account all
                  relevant factors.

                  The foregoing summary of the rights of dissenting holders of
                  Shares under Delaware Law does not purport to be a complete
                  statement of the procedures to be followed by holders of
                  Shares desiring to exercise any dissenters' rights under
                  Delaware Law. The preservation and exercise of dissenters'
                  rights require strict adherence to the applicable provisions
                  of Delaware Law. The provisions of Section 262 are complex and
                  technical in nature. Holders desiring to exercise their
                  appraisal rights may wish to consult counsel, since the
                  failure to comply strictly with these provisions will result
                  in the loss of their appraisal rights."

                                       4


ITEM 7. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

1.  Item 7 of the Schedule TO is hereby amended and supplemented by adding the
    following paragraphs after the end of Section 9 of the Offer to Purchase on
    page 13 of thereof, which had previously been incorporated by reference into
    the Schedule TO:

                          "Parent has the ability to borrow up to approximately
                  $1.6 billion pursuant to (i) a $1.0 billion revolving credit
                  facility entered into by Parent on May 31, 2002 that
                  terminates in May 2003, and (ii) a $600 million revolving
                  credit facility entered into by Parent on August 15, 2001,
                  that terminates in August 2006. These agreements, filed as
                  exhibits (b)(1) and (b)(2), respectively, to this Schedule TO
                  and incorporated herein by reference thereto, were entered
                  into in the ordinary course by Parent and not specifically for
                  the purpose of the Offer. Each of the revolving credit
                  facilities is among Parent and a syndicate of lenders, the
                  composition of which may change from time to time.

                          Each of the $1.0 billion and the $600 million credit
                  facility makes available to Parent U.S. dollar denominated
                  loans, Euro dollar loans, letters of credit, multi-currency
                  loans and local currency loans. The amounts borrowed under
                  each facility bears a variable interest rate on (i) U.S.
                  dollar denominated same day loans, based upon the greater of
                  the applicable prime rate, a specified base CD rate plus 1%,
                  or the Federal Funds Effective Rate plus 0.5%, and on
                  (ii) Eurodollar denominated loans and multi-currency
                  denominated loans, based on the rate per annum determined by
                  the credit facility's administrative agent to be the offered
                  rate for deposits in the applicable currency with a term
                  comparable to the interest period of such loan plus an
                  applicable margin based upon Parent's then current credit
                  rating. Both the $1.0 billion and the $600 million credit
                  facilities are unsecured and contain customary negative and
                  affirmative covenants, including financial covenants, conduct
                  of business covenants, limitations on liens and indebtedness
                  and limitations on fundamental changes. For more information
                  regarding the Parent's available borrowings pursuant to the
                  revolving credit facilities, including any of the non-U.S.
                  currency loans, please see exhibits (b)(1) and (b)(2) to
                  this Schedule TO."

ITEM 11. ADDITIONAL INFORMATION.

1.  Item 11(a)(i) of the Schedule TO is hereby amended and supplemented by
    replacing the first sentence of the first paragraph of the section of the
    Offer to Purchase entitled "Stockholders Agreement" on page 25 thereof,
    which had previously been incorporated by reference into the Schedule TO,
    with the following sentence:

                  "The following is a summary of certain provisions of the
                  Stockholders Agreement entered into with each of the following
                  BEI stockholders: First Chicago Equity Corporation, affiliates
                  of Diaz Altschul, LLP, the Delta Opportunity Funds,

                  M. Richart, Jordan Davis and Radius Venture Partners I, L.P.
                  (collectively, the "Supporting Stockholders")."

2.  Item 11(a)(i) of the Schedule TO is hereby amended and supplemented by
    deleting the clause ", exercisable under certain limited circumstances," in
    the last paragraph entitled "Grant of Option" on page 25 of the Offer to
    Purchase, which had previously been incorporated by reference into the
    Schedule TO, and inserting the following sentence at the end of such
    paragraph:

                  "Such options granted by each of the Supporting Stockholders
                  to Purchaser may be exercised by Purchaser only in connection
                  with or after the initial purchase of

                                       5


                  Shares pursuant to the Offer, and only to the extent that a
                  number of options are concurrently exercised and a number of
                  Shares are concurrently purchased in the Offer such that,
                  after giving effect to such exercises and purchases, the
                  Purchaser or an affiliate thereof would own Shares and stock
                  options constituting not less than a majority of the then
                  outstanding Common Stock (including, without limitation, all
                  Common Shares issuable upon the conversion of Series A Shares
                  or upon the exercise or conversion of any options, warrants,
                  rights or other convertible securities), or such higher
                  percentage of the Common Shares as may be required to approve
                  the Merger pursuant to the Restated Certificate of
                  Incorporation of BEI or applicable law."
