                     NOTES TO CONDENSED FINANCIAL STATEMENTS

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

[1]      BASIS OF PRESENTATION:

         The accompanying condensed financial statements as of June 30, 2003 and
         for the three and six month periods ended June 30, 2003 and June 30,
         2002, are unaudited. In the opinion of the management of Network-1
         Security Solutions, Inc. (the "Company"), the condensed financial
         statements contain all adjustments which the Company considers
         necessary for the fair presentation of the Company's financial position
         as of June 30, 2003, the results of its operations for the three and
         six months ended June 30, 2003 and 2002 and its cash flows for the six
         months ended June 30, 2003 and June 30, 2002. 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-QSB. 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, 2002 included in the Company's Annual
         Report on Form 10-KSB filed with the Securities and Exchange
         Commission. The results of operations for the six months ended June 30,
         2003 and 2002 are not necessarily indicative of the results of
         operations to be expected for the full year.

[2]      BUSINESS:

         The Company developed, marketed, licensed and supported its proprietary
         network security software products designed to provide comprehensive
         security to computer networks. The Company also provided maintenance
         and training services.

         In December 2002, the Company discontinued its software product line
         and associated operations, ceased its product development and
         substantially eliminated its sales and marketing efforts and during May
         2003, sold substantially all of its intellectual property. Through a
         series of layoffs, the Company has reduced its workforce to a current
         level of two employees and a consultant. The Company has closed its
         various offices upon termination of leases during 2002 and 2003.
         Management is focusing its efforts on seeking a merger candidate for
         the Company or other strategic transaction.

[3]      STOCK-BASED COMPENSATION:

         The Company accounts for stock-based employee compensation under
         Accounting Principles Board ("APB") Opinion No. 25, "Accounting for
         Stock Issued to Employees", and related interpretations. The Company
         has adopted the disclosure-only provisions of Statement of Financial
         Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
         Compensation" and SFAS No. 148, "Accounting for Stock-Based
         Compensation - Transition and Disclosure", which was released in
         December 2002 as an amendment of SFAS No. 123. The following table
         illustrates the effect on net income (loss) and loss per share if the
         fair value-based method had been applied to all awards.

[5]      EARNINGS (LOSS) PER SHARE:

         Basic earnings (loss) per share is calculated by dividing the net
         income (loss) by the weighted average number of outstanding common
         shares during the period. Diluted earnings (loss) per share data
         includes the dilutive effects of options, warrants and convertible
         securities. Potential dilutive shares of 17,823,724 and 17,985,282 are
         outstanding for the three and six month periods ending June 30, 2003,
         respectively. However, these shares are not included in the calculation
         of diluted earnings per share because the options and warrants exercise
         prices and the preferred shares conversion prices were greater than the
         average market price of the Company's common stock during the three and
         six month periods ending June 30, 2003. Potential shares of 19,002,335
         for the three and six months ended June 30, 2002 are anti-dilutive and
         are not included in the calculation of diluted loss per share. Such
         potential common shares reflect options, warrants, convertible
         preferred stock and convertible notes.

[6]      CASH CONCENTRATION:

         The Company places cash investments in high quality financial
         institutions insured by the Federal Deposit Insurance Corporation
         ("FDIC"). At June 30, 2003, the Company maintained cash balances of
         $1,456,000 in excess of FDIC limits.


NOTE B - LIABILITY TO BE SETTLED IN EQUITY INSTRUMENTS

         On April 18, 2002, in consideration of additional consulting and
         financial advisory services, the Company issued to CMH Capital
         Management Corp.("CMH" ) options to purchase 750,000 shares of the
         common stock at an exercise price of $1.20 per share, which was the
         market price of the Company's common stock on the date of issuance.
         Corey M.Horowitz, Chairman of the Board of Directors of the Company, is
         the sole owner and officer of CMH. The shares underlying the option
         shall vest over a three-year period in equal amounts of 250,000 shares
         per year beginning April 18, 2003. In addition, the shares underlying
         the option shall vest in full in the event of a "change of control" or
         in the event that the closing price of the Company's common stock
         reaches a minimum of $3.50 per share for 20 consecutive trading days.
         These options are treated as contingent options and valued utilizing
         the Black-Scholes option pricing model at each balance sheet date.
         These options were originally priced in the quarter ended June 30, 2002
         at $416,000. Subsequently, they were revalued to $55,000 at December
         31, 2002 and $14,000 at March 31, 2003. The fair value of these options
         remained unchanged at April 18, 2003. On April 18, 2003, 250,000 of
         these options, having fair value of $5,000 as of that date, vested.
         Accordingly, $5,000 was reallocated to Additional Paid-in-Capital by
         correspondingly reducing the liability. The options to purchase the
         remaining 500,000 shares continue to be treated as contingent options
         and valued utilizing the Black-Scholes option pricing model at each
         balance sheet date using the same weighted average assumptions as
         stated in Note A[3]. At June 30, 2003 these 500,000 options were valued
         at $9,000.


NOTE C - GAIN ON SALE OF ASSETS

         On May 30, 2003, the Company completed the sale of its CyberwallPlus
         technology and related intellectual property (the "Assets") and
         assignment of its rights under the Falconstar Agreement for aggregate
         proceeds of $415,000. The carrying value of these Assets was written
         down to zero in the third quarter of 2002. The $415,000 is reflected as
         "Gain on Sale of Assets" in the condensed statements of operations.

NOTE D - LITIGATION

         In January 2003, the former Chief Financial Officer and a director of
         the Company commenced a lawsuit against the Company for breach of his
         employment agreement for $190,000. Management believes that it has
         meritorious defenses to the claims asserted. Accordingly, the Company
         has not accrued any amount at June 30, 2003 that might result from the
         outcome of this litigation.

NOTE E - SETTLEMENT WITH FORMER CHIEF EXECUTIVE OFFICER (THE "FORMER CEO")

         In January 2003, the former CEO of the Company commenced a lawsuit
         against the Company for breach of his employment agreement for
         $200,000. In June 2003, the Company entered into a settlement in which
         the Company agreed to pay approximately $127,000 to the Former CEO in
         full settlement of all claims asserted, which was charged to expense
         during the year ended December 31, 2002. In addition, as part of the
         settlement, the Former CEO agreed to forfeit his options to purchase
         1,200,000 shares of the Company's common stock.

Item 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


THIS QUARTERLY REPORT ON FORM 10-QSB CONTAINS FORWARD-LOOKING STATEMENTS WITHIN
THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), AND SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED (THE "EXCHANGE ACT"). 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 PAGE 10 OF OUR
ANNUAL REPORT ON FORM 10-KSB FOR THE YEAR ENDED DECEMBER 31, 2002.

OVERVIEW

Until December 2002, Network-1 Security Solutions, Inc. (the "Company")
developed, marketed and licensed security software products designed to prevent
unauthorized access to information residing on an enterprise's computers. In
December 2002, the Company discontinued offering its security software product
line as it was unable to achieve sufficient product revenue to support the
expenses of such operations. Management is focusing its efforts on seeking a
merger candidate or other strategic transaction for the Company. In May 2003,
the Company completed the sale of its CyberwallPlus technology and related
intellectual property to an unrelated third party for $415,000.

Results of Operations:

THREE MONTHS ENDED JUNE 30, 2003 COMPARED TO THREE MONTHS ENDED JUNE 30, 2002

Revenues decreased by $79,000 or 33%, from $243,000 for the three months ended
June 30, 2002 to $164,000 for the three months ended June 30, 2003. Revenues
during the quarter of $130,000 were related to the recognition of deferred
revenue relating to the Falconstor Agreement. Revenues during the quarter of
$34,000 were related to the amortization of deferred maintenance revenues from
customers who had elected to purchase maintenance and support contracts in
earlier periods. The Company's lack of new license revenues for the three months
ended June 30, 2003 resulted from the Company's decision to discontinue its
software product line in December 2002.

The cost of revenues for the three months ended June 30, 2003 was $17,000. This
cost relates to one employee who provides services under the Company's
maintenance and support contracts. Amortization of software development costs
was $125,000 for the three months ended June 30, 2002. Cost of licenses
consisted of software media (disks), documentation, product packaging,
production costs and product royalties. Cost of licenses was $7,000 for the

contracts. Cost of services decreased by $25,000 or 60% from $42,000 for the
three months ended June 30, 2002 to $17,000 for the three months ended June 30,
2003. The decrease in the cost of revenue during the quarter ended June 30, 2003
is directly a result of the Company's decision to discontinue its software
product line in December 2002.

Gross profit was $147,000 for the three months ended June 30, 2003 compared to a
gross profit of $69,000 for the three months ended June 30, 2002, representing

ended June 30, 2002. No provision for or benefit from federal, state or foreign
income taxes was recorded for three months ended June 30, 2003 and 2002 because
the Company incurred net operating losses and fully reserved its deferred tax
assets as their future realization could not be determined.

On May 30, 2003, the Company completed the sale of its CyberwallPlus technology
and related intellectual property (the "Assets") and assignment of its rights

Liquidity and Capital Resources

At June 30, 2003, the Company had $1,550,000 of cash and cash equivalents and
working capital of $1,103,000. Net cash used in operating activities was
$2,788,000 during the six months ended June 30, 2002 and net cash used in
operating activities was $894,000 during the six months ended June 30, 2003. Net
cash used in operating activities for the six months ended June 30, 2003 was
primarily attributable to a decrease in accounts payable, accrued expenses and
other current liabilities of $329,000 and the recognition of deferred revenue of
$206,000 which was partially offset by an increase in prepaid expenses of
$57,000 and depreciation and amortization expenses of $22,000. Net cash used in
investing activities during the six months ended June 30, 2002 was $310,000.

The Company's operating activities during the six months ended June 30, 2003
were financed with the remaining funds raised in the 2001 financing of
$6,765,000 and the $415,000 received from the Company's sale of its
CyberwallPLUS software and related intellectual property. The Company does not
currently have a line of credit from a commercial bank or other institution.

                       NETWORK-1 SECURITY SOLUTIONS, INC.

The Company anticipates, based on currently proposed plans and assumptions, that
its cash balance of approximately $1,266,000 as of October 31, 2003 will be
sufficient to satisfy the Company's limited operations and capital requirements
until at least October 2004. There can be no assurance, however, that such funds
will not be expended prior thereto. In the event the Company's plans change, or
its assumptions change, or prove to be inaccurate (due to unanticipated
expenses, difficulties, delays or otherwise), the Company may have insufficient
funds to support its operations prior to October 2004. In the third and fourth
quarters of 2002, the Company instituted certain measures to reduce its overhead
including decreasing its headcount from 39 employees to its current level of two
employees and one consultant and the closing of its China development office and
its Taiwan sales office. In December 2002 the Company discontinued its product
offering in order to preserve cash as the Company continues to seek a merger or
other strategic transaction. In May 2003, the Company completed the sale of its
CyberwallPlus technology and related intellectual property for an aggregate
consideration of $415,000. The Company is actively engaged in seeking merger
candidates or other strategic transaction. There is, however, no assurance that
the Company will consummate such a transaction, or that any such transaction
will be successful. The inability of the Company to consummate a merger
transaction or strategic transaction would have a material adverse effect on the
Company. In addition, any such merger or other strategic transaction may involve
substantial dilution to the interests of the Company's existing stockholders.

Item 3: Controls and Procedures.

Based on his evaluation, as of a date within 90 days of the filing of this Form
10-QSB, the Company's Interim Chief Executive Officer and Chief Financial
Officer has concluded that the Company's controls and procedures (as defined in
Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are
effective.

PART II. OTHER INFORMATION

Item 1.  LEGAL PROCEEDINGS.

         In January 2003, Richard J. Kosinski, former Chief Executive Officer,
President and a director, and Murray P. Fish, former Chief Financial Officer and
a director, commenced lawsuits against the Company in the Commonwealth of
Massachusetts, County of Essex, Superior Court, seeking severance and bonus
compensation and other benefits allegedly due them of $200,000 and $190,000,
respectively. Messrs. Kosinski and Fish also moved for an order of attachment,
temporary restraining order and preliminary injunction to prevent the Company
from transferring an aggregate of $400,000 of its funds pending the outcome of
the lawsuits. In February 2003, the Court denied plaintiffs' motions.

In June 2003, the Company entered into a settlement agreement with Mr. Kosinski
pursuant to which the Company paid Mr. Kosinski the sum of $127,000 in full
settlement of all claims asserted by him in the litigation. In addition, as part
of the settlement, Mr. Kosinski agreed to forfeit options to purchase 1,200,000
shares of the Company's Common Stock.

The Company intends to vigorously defend the lawsuit by Mr. Fish seeking
$190,000 in severance, bonus and other benefits allegedly due him and believes
it has meritorious defenses to the claims asserted.
