NOTE A - NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

[1] BASIS OF PRESENTATION:

The accompanying condensed financial statements as of September 30, 2009 and for
the three and nine month periods ended September 30, 2009 and September 30, 2008
are unaudited, but in the opinion of the management of Network-1 Security
Solutions, Inc. (the "Company") contain all adjustments consisting only of
normal recurring items which the Company considers necessary for the fair
presentation of the Company's financial position as of September 30, 2009, and
the results of its operations and its cash flows for the three and nine month
periods ended September 30, 2009 and September 30, 2008. The condensed financial
statements included herein have been prepared in accordance with the accounting
principles generally accepted in the United States of America for interim
financial information and the instructions to Form 10-Q. Accordingly, certain
information and footnote disclosures normally included in the financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been omitted pursuant to such rules and
regulations, although management believes that the disclosures are adequate to
make the information presented not misleading. These financial statements should
be read in conjunction with the audited financial statements for the year ended
December 31, 2008 included in the Company's Annual Report on Form 10-K filed
with the Securities and Exchange Commission. The results of operations for the
nine months ended September 30, 2009 are not necessarily indicative of the
results of operations to be expected for the full year.

[2] BUSINESS:

(a) The principal business of the Company is the acquisition, development,
licensing and protection of its intellectual property. The Company presently
owns six patents (the "Patent Portfolio") covering various telecommunications
and data networking technologies including, among others, patents covering the
delivery of power over Ethernet cable for the purpose of remotely powering
network devices, and the transmission of audio, video and data over computer and
telephony networks. The Company's strategy is to pursue licensing and strategic
business alliances with companies in the industries that manufacture and sell
products that make use of the technologies underlying its patents as well as
with other users of the technology who benefit directly from the technology
including corporate, educational and governmental entities. To date, the
Company's efforts with respect to its Patent Portfolio have focused on licensing
its Remote Power Patent (U.S. Patent No. 6,218,930). As of September 30, 2009,
the Company had entered into 6 license agreements with respect to its Remote
Power Patent which, among others, included license agreements with D-Link (See
Note D[2]), Microsemi Corporation (See Note D[3]) and Netgear, Inc. (See Note
D[1]. The Company may seek to acquire additional patents in the future.

                                       6


[2] BUSINESS: (CONTINUED)

(b) As reflected in the accompanying financial statements, the Company has
incurred substantial losses and has experienced net cash outflows from
operations for the year ended December 31, 2008 and the three and nine month
period ended September 30, 2009. For the year ended December 31, 2008 and the
three and nine month period ended September 30, 2009, the Company had revenue
$349,000, $141,000 and $655,000, respectively. The Company will continue to have
operating losses for the foreseeable future until it is successful in licensing
its patented technologies. The Company has been dependent upon equity financing
to fund its operations. The Company had cash and cash equivalents of $3,450,000
as of September 30, 2009. The Company believes its current cash position will
more likely than not be sufficient to satisfy the Company's operations and
capital requirements until at least December 31, 2010, although there can be no
assurance that such funds will not be expended prior thereto.


[3] STOCK-BASED COMPENSATION:

On January 2, 2008, the Company granted the following options: (i) a 5 year

[3] STOCK-BASED COMPENSATION: (CONTINUED)


            shares owned by three principal stockholders of the Company), at an
            exercise price of $2.00 per share, which warrants were issued as
            part of the Company's private placement completed in April 2007,
            were adjusted to an exercise price of $1.75 per share for the
            remaining exercise period of such warrants (April 16, 2012), subject
            to the adjustments set forth in item (iv) below; and

     (iv)   in the event that any holders of the above referenced outstanding
            warrants, issued as part of the Company's December 2004/January 2005
            or the April 2007 private placements, exercise such warrants at
            anytime up to and including December 31, 2009, the exercise price of
            all such warrants shall adjust to $1.25 per share.

On June 8, 2009, as part of the terms of the Company's new employment agreement

price of $0.83 per share. The options vest in equal quarterly amounts of 62,500
shares beginning June 30, 2009 through March 31, 2012, subject to accelerated
vesting upon a change of control (See Note C). During the nine months ended
September 30, 2009 the Company recognized non-cash compensation expense of
$74,000 for these options based on the Black-Scholes option-pricing model.

In addition, on June 8, 2009, as part of the terms of the Company's new
employment agreement with its Chairman and Chief Executive Officer, the Board of
Directors extended the expiration dates for 5 years of options to purchase an
aggregate of 417,500 shares (which were to expire in 2009) issued to the
Company's Chairman and Chief Executive. The Company recorded non-cash
compensation of $132,000 relating to the aforementioned extension of such option
expiration dates.

The fair value of each Company option grant on the date of grant is estimated
using the Black-Scholes option-pricing model utilizing the following weighted
average assumptions:

calculation of diluted loss per share. Such potential common shares reflect
outstanding options and warrants.

NOTE C - EMPLOYMENT ARRANGEMENTS AND OTHER AGREEMENTS

On June 8, 2009, the Company entered into a new Employment Agreement with Corey

covered below) with respect to the Company's Remote Power Patent and 12.5% of
the Company's royalties and other payments with respect to the Company's other
patents besides the Remote Power Patent (the "Additional Patents") (all before

patented technologies (including patents owned as of the date of the Agreement
and acquired or licensed on an exclusive basis during the period in which Mr.

if terminated "For Cause" by the Company or "Without Good Reason" by Mr.
Horowitz.

NOTE D - LITIGATION

[1] In February 2008, the Company commenced litigation against several major
data networking equipment manufacturers in the United States District Court for
the Eastern District of Texas, Tyler Division, for infringement of the Company's
Remote Power Patent. The complaint named as defendants Cisco Systems, Inc.,
Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme
Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. The
Company seeks injunctive relief and monetary damages for infringement based upon
reasonable royalties as well as treble damages for the defendants continued
willful infringement of the Remote Power Patent. The Defendants, in their
answers to the complaint, asserted that they do not infringe any valid claim of
the Remote Power Patent, and further asserted that, based on several different
theories, the patent claims are invalid or unenforceable. In addition to these
defenses, the defendants also asserted counterclaims for, among other things,
non-infringement, invalidity, and unenforceability of the Remote Power Patent. A
Markman hearing, a hearing on claim construction of our Remote Power Patent, is
currently scheduled for December, 2009 and a trial date has been set for July,
2010. In the event that the court determines that the Remote Power Patent is not
valid or enforceable, and/or that the defendants do not infringe, any such
determination would have a material adverse effect on the Company.

In May 2009 the Company settled the above referenced litigation with respect to
Netgear, Inc. ("Netgear"). As part of the settlement and under the Company's
Special Licensing Program, Netgear entered into a license agreement with the
Company for the Remote Power Patent, effective April 1, 2009. Under the terms of
the license, Netgear licenses the Remote Power Patent from the Company for its
full term which expires in March 2020, and pays quarterly royalties (beginning
as of April 1, 2009) based on its sales of Power over Ethernet products,
including those PoE products which comply with the Institute of Electrical and
Electronic Engineers 802.3af and 802.3at Standards. Licensed products include
Netgear's Power over Ethernet enabled switches and wireless access points. The
royalty rates included in the license are 1.7% of the sales price of Power
Sourcing Equipment, which includes Ethernet switches, and 2% of the sales price
of Powered

                                       12


NOTE D - LITIGATION: (CONTINUED)

Devices, which includes wireless access points. The royalty rates are subject to
adjustment, under certain circumstances, if the Company grants a license to
other licensees with lower royalty rates and Netgear is able to and agrees to
assume all material terms and conditions of such other license. In addition,
Netgear paid the Company $350,000 upon the signing of the license agreement.

[2] In August 2005, the Company commenced patent litigation against D-Link
Corporation and D-Link Systems, Incorporated (collectively "D-Link") in the
United States District Court for the Eastern District of Texas, Tyler division
(Civil Action No. 6:05W291), for infringement of the Company's Remote Power
Patent (the "D-Link Litigation"). The complaint sought, among other things, a
judgment that the Company's Remote Power Patent is enforceable and has been
infringed by the defendants. The Company also sought a permanent injunction
restraining the defendants from continued infringement, or active inducement of
infringement by others, of the Remote Power Patent.

In August 2007, the Company finalized the settlement of the D-Link Litigation
(see below). Under the terms of the settlement, D-Link entered into a license
agreement for the Company's Remote Power Patent the terms of which include
monthly royalty payments of 3.25% (subject to adjustment as noted below) of the
net sales of D-Link Power over Ethernet products, including those products which
comply with the IEEE 802.3af and 802.3at Standards, for the full term of the
Remote Power Patent, which expires in March 2020. In addition, D-Link paid the
Company $100,000 upon signing of the Settlement Agreement. The royalty rate is
subject to adjustment to a rate consistent with other similarly situated
licensees of the Remote Power Patent based on units of shipments of licensed
products. In June 2009, based upon several licenses issued to third parties
under the Company's Special Licensing Program, the Company agreed with D-Link to
adjust the royalty rate to 1.7% of the sales price for Power Servicing Equipment
(which includes Ethernet switches) and 2.0% of the sales price for Powered
Devices (which includes wireless access points).

[3] On November 16, 2005 the Company entered into a Settlement Agreement with
PowerDsine, Inc and PowerDsine Ltd. which dismissed, with prejudice, a civil
action brought by PowerDsine in the United States District Court for the
Southern District of New York that sought a declaratory judgment that U.S.
Patent No. 6,218,930 (the "Remote Power Patent") owned by the Company was
invalid and not infringed by PowerDsine and/or its customers. Under the terms of
the Settlement Agreement, the Company agreed that it will not initiate
litigation against PowerDsine for its sale of Power over Ethernet (PoE)
integrated circuits. In addition, the Company agreed that it will not seek
damages for infringement from customers that incorporate PowerDsine integrated
circuit products in PoE capable Ethernet switches manufactured on or before
April 30, 2006. PowerDsine agreed that it will not initiate, assist or cooperate
in any legal action relating to the Remote Power Patent.

In June 2008, the Company entered into a new agreement with Microsemi
Corp-Analog Mixed Signal Group Ltd ("Microsemi Analog"), previously PowerDsine
Ltd, a subsidiary of Microsemi Corporation ("Microsemi"), a leading manufacturer
of high performance analog mixed-signal integrated circuits and high reliability
semiconductors, which, among other things, amended the prior Settlement
Agreement entered into between the parties in November 2005. As part of the
Company's Special Licensing Program and its agreement with Microsemi Analog
entered into in June 2008, Microsemi, entered into a license agreement, dated
August 13, 2008, with the Company with respect to the Remote Power Patent. The
license agreement provides that Microsemi is

                                       13


obligated to pay the Company quarterly royalty payments of 2% of the sales price
for certain of Microsemi's Midspan PoE products for the full term of the Remote
Power Patent (March 2020).

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATION

THIS QUARTERLY REPORT ON FORM 10-Q CONTAINS FORWARD-LOOKING STATEMENTS WHICH ARE
STATEMENTS THAT INCLUDE INFORMATION BASED UPON BELIEF OF OUR MANAGEMENT, AS WELL
AS ASSUMPTIONS MADE BY AND INFORMATION AVAILABLE TO MANAGEMENT. STATEMENTS
CONTAINING TERMS SUCH AS "BELIEVES", "EXPECTS", "ANTICIPATES", "INTENDS" OR
SIMILAR WORDS ARE INTENDED TO IDENTIFY FORWARD LOOKING STATEMENTS. ACTUAL
RESULTS, EVENTS AND CIRCUMSTANCES (INCLUDING FUTURE PERFORMANCE, RESULTS AND
TRENDS) COULD DIFFER MATERIALLY FROM THOSE SET FORTH IN SUCH STATEMENTS DUE TO
VARIOUS RISKS AND UNCERTAINTIES, INCLUDING, BUT NOT LIMITED TO, THOSE DISCUSSED
BEGINNING ON PAGES 8-14 OF OUR ANNUAL REPORT ON FORM 10-K FOR THE YEAR 2008 AND
AS DISCUSSED IN THIS QUARTERLY REPORT ON FORM 10-Q.

OVERVIEW

     Our principal business is the acquisition, development, licensing and
protection of our intellectual property. We presently own six patents covering
various telecommunications and data networking technologies (the "Patent
Portfolio") including, among others, patents covering the delivery of power over
Ethernet for the purpose of remotely powering network devices, and the
transmission of audio, video and data over computer and telephony networks. Our
strategy is to pursue licensing and strategic business alliances with companies
in the industries that manufacture and sell products that make use of the
technologies underlying our patents as well as with other users of the
technology who benefit directly from the technology including corporate,
educational and governmental entities.

     To date, our efforts with respect to our Patent Portfolio have focused on
licensing our patent (U.S. Patent No. 6,218,930) covering the control of power
delivery over Ethernet cables (the "Remote Power Patent"). As of September 30,
2009, we had entered into 6 license agreements with respect to our Remote Power
Patent which, among others, included license agreements with D-Link, Microsemi
Corporation and Netgear, Inc. (See Note [D] to our financial statements included
as part of this quarterly report). We may seek to acquire additional patents in
the future.

     To date we have incurred significant losses and at September 30, 2009 had
an accumulated deficit of $(52,611,000). For the year ended December 31, 2008
and for the three and nine months ended September 30, 2009, we incurred net
losses of $(1,618,000), $(457,000) and $(1,716,000), respectively. We anticipate
that we will continue to incur losses until we enter into additional license
agreements with respect to our patented technologies or achieve material
additional revenue from our existing license agreements. We achieved revenue of
$349,000 for the year ended December 31, 2008 and $655,000 for the nine months
ended September 30, 2009 with respect to royalties pertaining to our Remote
Power Patent. Our inability to consummate additional material license agreements
or achieve material additional revenue from our existing license agreements
would have a material adverse effect on our operations.

                                       14


     Our success and ability to generate revenue is largely dependent on our
ability to consummate licensing arrangements with third parties. In November
2004, we entered into an agreement with ThinkFire Services USA, Ltd.
("ThinkFire") pursuant to which ThinkFire has been granted the exclusive
worldwide rights to negotiate license agreements for our Remote Power Patent
with certain agreed-upon potential licensees. We agreed to pay ThinkFire a fee
ranging from 5% to 20% of the royalty payments received from license agreements
consummated by ThinkFire on our behalf after we recover our expenses.

     In February 2008, we commenced litigation against eight major data
networking equipment manufacturers in the United States District Court for the
Eastern District of Texas, Tyler Division, for infringement of our Remote Power
Patent. The complaint named as defendants Cisco Systems, Inc., Cisco Linksys,
LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc.,
Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief
and monetary damages for infringement based upon reasonable royalties as well as
treble damages for the defendant's continued willful infringement of our Remote
Power Patent. All of the defendants answered the complaint and asserted that
they do not infringe any valid claim of our Remote Power Patent, and further
asserted that, based on several different theories, the patent claims are
invalid or unenforceable. In addition to these defenses, the defendants also
asserted counterclaims for, among other things, non-infringement, invalidity,
and unenforceability of our Remote Power Patent. A Markman hearing, a hearing on
claim construction of our Remote Power Patent, is currently scheduled for
December, 2009 and a trial date has been set for July, 2010. In the event that
the Court determines that our Remote Power Patent is not valid or enforceable,
and/or that the defendants do not infringe, any such determination would have a
material adverse effect on us.

     On May 29, 2009 we announced that we had agreed to settle the above
referenced litigation with respect to Netgear, Inc. ("Netgear"). As part of the
settlement and under our Special Licensing Program, Netgear entered into a
license agreement with us for our Remote Power Patent. Under the terms of the
license, Netgear licenses the Remote Power Patent from us for its full term
(which expires in March 2020), and pays quarterly royalties (beginning as of
April 1, 2009) based on its sales of Power over Ethernet products, including
those Power over Ethernet products which comply with the Institute of Electrical
and Electronic Engineers 802.3af and 802.3at Standards. Licensed products
include Netgear's Power over Ethernet enabled switches and wireless access
points. The royalty rates included in the license are 1.7% of the sales price of
Power Sourcing Equipment, which includes Ethernet switches, and 2% of the sales
price of Powered Devices, which includes wireless access points. The royalty
rates are subject to adjustment, under certain circumstances, if we grant a
license to other licensees with lower royalty rates and Netgear is able to and
agrees to assume all material terms and conditions of the other license. In
addition, Netgear made a payment to us of $350,000 with respect to the
settlement.

     In August 2007 we finalized the settlement of our patent litigation against
D-Link in the United States District Court for the Eastern District of Texas,
Tyler Division, for infringement of our Remote Power Patent (U.S. Patent No.
6,218,930). Under the terms of the settlement, D-Link licenses our Remote Power
Patent the terms of which include monthly royalty payments of 3.25% (as adjusted
as noted below) of the net sales of D-Link branded Power over Ethernet products,
including those products which comply with the IEEE 802.3af and 802.3at
Standards, for the full life of our Remote Power Patent, which expires in March
2020. The royalty rate is

                                       15


subject to adjustment to a rate consistent with other similarly situated
licensees of our Remote Power Patent based on units of shipments of licensed
products. In addition, D-Link paid us $100,000 upon signing the settlement
agreement. In June 2009, based upon several licenses issued to third parties
under our Special Licensing Program, we agreed with D-Link to adjust the royalty
rate to 1.7% of the sales price for Power Servicing Equipment (which includes
Ethernet switches) and 2.0% of the sales price for Powered Devices (which
includes wireless access points).

     As part of our Special Licensing Program and our agreement with Microsemi
Corp-Analog Mixed Signal Group Ltd. ("Microsemi-Analog") entered into in June
2008, Microsemi Corporation ("Microsemi"), the parent company of
Microsemi-Analog, entered into a license agreement, dated August 13, 2008, with
us with respect to the Remote Power Patent. The license agreement provides that
Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales
price for certain of Microsemi's Midspan PoE products for the full term of the
Remote Power Patent (through March 2020).

     Notwithstanding our license agreements, including those with D-Link,
Microsemi and Netgear described above, there is no assurance that we will
achieve significant royalty revenue from such licenses, that we will be able to
achieve additional material license agreements with third parties relating to
our Remote Power Patent or our other patents, or that such license arrangements
will result in material revenue to us.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 2009 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2008

     We had revenue of $141,000 and $106,000 for the three months ended
September 30, 2009 and 2008, respectively, which were related to the receipt of
royalties from licensees of our Remote Power Patent. The increased revenue of
$35,000 for the three months ended September 30, 2009 as compared to the three
month period ended September 30, 2008 was due primarily to additional licensees
of our Remote Power Patent and increased royalties from our licensees.

     We had a cost of revenue of $4,000 and $5,000 for the three months ended
September 30, 2009 and 2008.

     The gross profit increased $36,000 from $101,000 for the three months ended
September 30, 2008 to $137,000 for the three months ended September 30, 2009.
Such increased gross profit was the result of increased licensing revenue for
the three months ended September 30, 2009.

     General and administrative expenses include overhead expenses, and finance,
accounting, legal and other professional services incurred by us. General and
administrative expenses increased by $103,000, from $439,000 the three months
ended September 30, 2008 to $542,000 for the three months ended September 30,
2009 due primarily to increased fees and expenses with respect to litigation
involving our Remote Power Patent.

     We incurred an operating loss of ($456,000) for the three months ended
September 30, 2009 compared with an operating loss of ($408,000) for the three
months ended September 30,

                                       16


2008. Included in the operating loss for the three months ended September 30,
2009 was $51,000 in charges relating to non-cash compensation expenses, as
compared to $70,000 for such non-cash compensation expenses for the three months
ended September 30, 2008.

     No provision for or benefit from federal, state or local income taxes was
recorded for the three months ended September 30, 2009 and September 30, 2008
because we incurred net operating losses and fully reserved our deferred tax
assets as their future realization could not be determined.

     As a result of the foregoing, we incurred a net loss of $(457,000) for the
three months ended September 30, 2009 compared with a net loss of $(383,000) for
the three months ended September 30, 2008.

NINE MONTHS ENDED SEPTEMBER 30, 2009 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
2008

     We had revenue of $655,000 and $240,000 for the nine months ended September
30, 2009 and 2008, respectively, which were related to the receipt of royalties
from licensees of our Remote Power Patent. The revenue increase of $415,000 for
the nine months ended September 30, 2009 as compared to the nine month period
ended September 30, 2008 was due primarily to the $350,000 payment from the
settlement of our litigation with Netgear, Inc., as well as additional royalties
from our licensees.

     We had a cost of royalties of $69,000 and $12,000 for the nine months ended
September 30, 2009 and 2008, respectively, which increase of $57,000 was related
to additional bonus compensation payable to our Chairman and Chief Executive
Officer pursuant to his employment agreement, and contingent legal fees paid to
Dovel & Luner, our patent litigation counsel.

     The gross profit for the nine months ended September 30, 2009 increased
$358,000 from $228,000 for the nine months ended September 30, 2008 to $586,000
for the nine months ended September 30, 2009. Such increased gross profit was
the result of increased revenue for the nine months ended September 30, 2009 due
primarily to the $350,000 upfront payment from settlement of our litigation with
Netgear, Inc., as well as additional royalties from our licensees.

     General and administrative expenses include overhead expenses, and finance,
accounting, legal and other professional services incurred by us. General and
administrative expenses increased by $296,000 from $1,209,000 for the nine
months ended September 30, 2008 to $1,505,000 for the nine months ended
September 30, 2009 due primarily to increased fees and expenses from our patent
litigation.

     We incurred an operating loss of ($1,716,000) for the nine months ended
September 30, 2009 compared with an operating loss of ($1,197,000) for the nine
months ended September 30, 2008. Included in the operating loss for the nine
months ended September 30, 2009 was $797,000 in charges relating to non-cash
compensation expenses primarily related to the adjustment of exercise prices for
outstanding options and warrants (see Note A[3] to our financial statements
included in this quarterly report) as compared to $216,000 for such non-cash
compensation expenses for nine months ended September 30, 2008.

                                       17


     No provision for or benefit from federal, state or local income taxes was
recorded for nine months ended September 30, 2009 and September 30, 2008 because
we incurred net operating losses and fully reserved our deferred tax assets as
their future realization could not be determined.

     As a result of the foregoing, we incurred a net loss of $(1,716,000) for
the nine months ended September 30, 2009 compared with a net loss of
$(1,104,000) for the nine months ended September 30, 2008.

LIQUIDITY AND CAPITAL RESOURCES

     We have financed our operations primarily from the sale of equity
securities and royalty revenue from licensing our Remote Power Patent. We
anticipate, based on currently proposed plans and assumptions, relating to our
operations, that our cash and cash equivalents of approximately $3,450,000 as of
September 30, 2009 will more likely than not be sufficient to satisfy our
operations and capital requirements until at least December 31, 2010. There can
be no assurance, however, that such funds will not be expended prior thereto. In
the event our plans change, or our assumptions change, or prove to be inaccurate
(due to unanticipated expenses, difficulties, delays or otherwise), we may have
insufficient funds to support our operations prior to December 31, 2010 Our
inability to consummate additional material licensing arrangements with respect
to our Remote Power Patent and generate revenues therefrom, achieve a material
increase in revenue from our existing licenses or obtain additional financing
when needed, would have a material adverse effect on our company, requiring us
to curtail or cease operations. In addition, any equity financing may involve
substantial dilution to our current stockholders.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

CONTRACTUAL OBLIGATIONS

We do not have any long-term debt, capital lease obligations, operating lease
obligations, purchase obligations or other long-term liabilities.


                                       18


CRITICAL ACCOUNTING POLICIES:

     Patents:

The Company owns a patent portfolio that relates to various telecommunications
and data networking technologies. The Company capitalizes the costs associated
with acquisition, registration and maintenance of the patents and amortizes
these assets over their remaining useful lives on a straight-line basis. Any
further payments made to maintain or develop the patents would be capitalized
and amortized over the balance of the useful life for the patents.

     Impairment of long-lived assets:

In accordance with Statement of Financial Accounting Standards ("SFAS") No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets", we record
impairment losses on long-lived assets used in operations or expected to be
disposed of when indicators of impairment exist and the cash flows expected to
be derived from those assets are less than carrying amounts of those assets.

     Use of estimates:

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not Applicable.

ITEM 4. CONTROLS AND PROCEDURES.

(a) Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer have reviewed our
disclosure controls and procedures as of the end of the period covered by this
Quarterly Report on Form 10-Q. Based upon this review, these officers concluded
that, as of the end of the period covered by this Quarterly Report on Form 10-Q,
our disclosure controls and procedures are effective to ensure that information
required to be disclosed by us in the reports we file or submit under Securities
Exchange Act of 1934 is recorded, processed, summarized and reported within the
time periods specified in the Securities and Exchange Commission's rules and
forms, and is accumulated and communicated to management, including our Chief
Executive Officer and Chief Financial Officer, as appropriate to allow timely
decisions regarding required disclosure.

(b) Changes in Internal Controls

There was no change in our internal control over financial reporting that
occurred during the fiscal quarter ended September 30, 2009 that has materially
affected, or is reasonably likely to materially affect, our internal control
over financial reporting.

                           PART II. OTHER INFORMATION

ITEM 1:  LEGAL PROCEEDINGS

   Pending Litigation Against Major Data Networking Equipment Manufacturers

In February 2008, we commenced litigation against eight major data networking
equipment manufacturers in the United States District Court for the Eastern
District of Texas, Tyler Division, for infringement of our Remote Power Patent.
The complaint named as defendants Cisco Systems, Inc., Cisco Linksys, LLC,
Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc.,
Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief
and monetary damages for infringement based upon reasonable royalties as well as
treble damages for the defendants' continued willful infringement of our Remote
Power Patent. The defendants, in their answers to our complaint, asserted that
they do not infringe any valid claim of our Remote Power Patent, and further
asserted that, based on several different theories, the patent claims are
invalid or unenforceable. In addition to these defenses, the defendants also
asserted counterclaims for, among other things, non-infringement, invalidity,
and unenforceability of our Remote Power Patent. A Markman hearing, a hearing on
claim construction of our Remote Power Patent, is scheduled for December, 2009
and a trial date has been set for July, 2010. In the event that the Court
determines that our Remote Power Patent is not valid or enforceable, and/or that
the defendants do not infringe, any such determination would have a material
adverse effect on our company.

On May 29, 2009 we announced that we had agreed to settle the above referenced
litigation with respect to Netgear, Inc. ("Netgear"). As part of the settlement
and under our Special Licensing Program, Netgear entered into a license
agreement with us for our Remote Power Patent and we agreed that all claims and
counterclaims involving Netgear in the litigation would be dismissed with
prejudice. Under the terms of the license, Netgear licenses the Remote Power
Patent from us for its full term (which expires in March 2020), and pays
quarterly royalties (beginning as of April 1, 2009) based on its sales of Power
over Ethernet products, including those Power over Ethernet products

                                       20


which comply with the Institute of Electrical and Electronic Engineers 802.3af
and 802.3at Standards. Licensed products include Netgear's Power over Ethernet
enabled switches and wireless access points. The royalty rates included in the
license are 1.7% of the sales price of Power Sourcing Equipment, which includes
Ethernet switches, and 2% of the sales price of Powered Devices, which includes
wireless access points. The royalty rates are subject to adjustment, under
certain circumstances, if we grant a license to other licensees with lower
royalty rates and Netgear is able to and agrees to assume all material terms and
conditions of such other license. In addition, Netgear made a payment of
$350,000 to us with respect to the settlement.

D-Link Settlement

In August 2005, we commenced patent litigation against D-Link Corporation and
D-Link Systems, Incorporated (collectively "D-Link") in the United States
District Court for the Eastern District of Texas, Tyler division, for
infringement of our Remote Power Patent. Our complaint sought, among other
things, a judgment that our Remote Power Patent is enforceable and has been
infringed by the defendants. We also sought a permanent injunction restraining
the defendants from continued infringement, or active inducement of infringement
by others, of our Remote Power Patent.

In August 2007, we finalized the settlement of our patent infringement
litigation against D-Link. Under the terms of the settlement, D-Link entered
into a license agreement for our Remote Power Patent the terms of which include
monthly royalty payments of 3.25% (subject to adjustment as noted below) of the
net sales of D-Link Power over Ethernet products, including those products which
comply with the IEEE 802.3af and 802.3at Standards, for the full term of our
Remote Power Patent, which expires in March 2020. In addition, D-Link paid us
$100,000 upon signing of the Settlement Agreement. The royalty rate is subject
to adjustment to a rate consistent with other similarly situated licensees of
our Remote Power Patent based on units of shipments of licensed products. In
June 2009, based upon several licenses issued to third parties under our Special
Licensing Program, we agreed with D-Link to adjust the royalty rate to 1.7% of
the sales price for Power Servicing Equipment (which includes Ethernet switches)
and 2.0% of the sales price for Powered Devices (which includes wireless access
points).

Microsemi - PowerDsine Settlement

On November 16, 2005, we entered into a Settlement Agreement with PowerDsine,
Inc. and PowerDsine Ltd. (collectively, "PowerDsine") which dismissed, with
prejudice, patent litigation brought by PowerDsine against us in March 2004 in
the United States District Court for the Southern District of New York that
sought a declaratory judgment that our Remote Power Patent was invalid and not
infringed by PowerDsine and/or its customers. Under the terms of the Settlement
Agreement, we agreed that, under certain circumstances, we will not initiate
litigation against PowerDsine for its sale of Power over Ethernet (PoE)
integrated circuits. In addition, we agreed that we will not seek damages for
infringement from customers that incorporate PowerDsine integrated circuit
products in PoE capable Ethernet switches manufactured on or before April 30,
2006. PowerDsine has agreed that it will not initiate, assist or cooperate in
any legal action relating to the Remote Power Patent. In June 2008 we entered
into a new agreement with Microsemi Corp-Analog Mixed Signal Group Ltd
("Microsemi Analog"), previously PowerDsine Ltd, a subsidiary of Microsemi
Corporation ("Microsemi"), a leading manufacturer of high performance analog
mixed-signal integrated circuits and high reliability semiconductors, which,
among other things, amended the prior Settlement Agreement entered into between
the parties in November 2005. As part of our Special Licensing

                                       21


Program and our agreement with Microsemi Analog entered into in June 2008,
Microsemi entered into a license agreement, dated August 13, 2008, with us with
respect to our Remote Power Patent. The license agreement provides that
Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales
price for certain of Microsemi's Midspan PoE products for the full term of our
Remote Power Patent (March 2020).
