                     VASCO DATA SECURITY INTERNATIONAL, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1 - BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements include the
accounts of VASCO Data Security International, Inc. and its subsidiaries
(collectively, the "Company" or "VASCO") and have been prepared pursuant to the
rules and regulations of the Securities and Exchange Commission regarding
interim financial reporting. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements and should be read in conjunction with the audited
consolidated financial statements included in the Company's Annual Report on
Form 10-K for the year ended December 31, 2001.

     In the opinion of management, the accompanying unaudited consolidated
financial statements have been prepared on the same basis as the audited
consolidated financial statements, and include all adjustments, consisting only
of normal recurring adjustments, necessary for the fair presentation of the
results of the interim periods presented. All significant intercompany accounts
and transactions have been eliminated. The operating results for the interim
periods presented are not necessarily indicative of the results expected for a
full year.


NOTE 2- GOODWILL AND OTHER INTANGIBLE ASSETS

         During the first quarter of 2002, VASCO implemented SFAS No. 142,
"Goodwill and Other Intangible Assets", which replaced the requirements to
amortize intangible assets with indefinite lives and goodwill with a requirement
for an impairment test. SFAS 142 also established requirements for identifiable
intangible assets. As a result, during the first quarter VASCO reclassified
$1,222,898 of intangible assets into goodwill. Operating income for the first
nine months of 2001 includes $137,468 of amortization of goodwill and other
intangible assets that are not included in 2002 results, because of the
implementation of SFAS No. 142.

Intangible asset data as of September 30, 2002 is as follows:

                                             Gross Carrying      Accumulated
                                                 Amount          Amortization
                                                 ------          ------------
Amortized intangible assets -
         Current technology                   $ 5,455,609        $ 3,401,569

Unamortized intangible assets - Goodwill      $ 1,222,898        $   972,931

Aggregate amortization expense -
For the nine months ended September 30, 2002  $   405,807

Estimated amortization expense for the year ended:
         December 31, 2002                    $   548,637
         December 31, 2003                        532,355
         December 31, 2004                        319,186
         December 31, 2005                        319,186

     Net loss would have been $137,468 lower and basic and diluted loss per
share would have decreased $.01 for the nine months ended September 30, 2001, if
SFAS 142 had been implemented at the beginning of that period. For the three
months ended September 30, 2001, net loss would have been $45,823 lower and
diluted loss per share would not have changed, if SFAS 142 had been implemented
at the beginning of that period.

                                      -7-






NOTE 3 - ACQUISITION

     On March 29, 2001, VASCO acquired approximately 90% of the outstanding
capital stock of Identikey, Ltd. in exchange for 366,913 shares of Company
common stock. In May 2002, VASCO acquired approximately 9.7% of the outstanding
stock of Identikey, Ltd. in exchange for 126,426 shares of Company common stock
and approximately $23,000 in cash. The value of the stock and cash exchanged for
these shares in May 2002 was approximately $308,000. The Company intends to
acquire the remaining shares outstanding during the fourth quarter of 2002.

NOTE 4 - INVENTORIES

     Inventories, consisting principally of hardware and component parts, are
stated at the lower of cost or market. Cost is determined using the
first-in-first-out (FIFO) method.

     Inventories are comprised of the following:

                                                  December 31,   September 30,

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

                                                  ------------   -------------
                     Total                        $  2,012,567   $   1,015,292
                                                  ============   =============

NOTE 5 - IMPACT OF ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED

     In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement
Obligations." SFAS 143 addresses financial accounting and reporting obligations
associated with the retirement of tangible long-lived assets and for the
associated asset retirement costs. SFAS 143 must be applied starting with fiscal
years beginning after June 15, 2002. Management is currently evaluating the
impact that the adoption of SFAS 143 will have on the consolidated financial
statements.

     In June 2002, the FSAB issued SFAS 146, Accounting for Costs Associated
with Exit or Disposal Activities, which addresses financial accounting and
reporting for costs associated with exit or disposal activities and nullifies
Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for
Certain Employee Termination Benefits and Other Costs to Exit an Activity
(including Certain Costs Incurred in a Restructuring)." SFAS 146 requires that a
liability for a cost associated with an exit or disposal activity be recognized
when the liability is incurred. Under EITF 94-3, a liability for an exit cost
was recognized at the date of an entity's commitment to an exit plan. SFAS 146
also establishes that the liability should initially be measured and recorded at
fair value. The Company will adopt the provisions of SFAS 146 for exit or
disposal activities that are initiated after December 31, 2002. The adoption of
SFAS 146 will not have an impact on the Company's historical consolidated
financial statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     VASCO designs, develops, markets and supports open standards-based hardware
and software security systems which manage and secure access to data.

CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995

     This Quarterly Report on Form 10-Q, including the "Management's Discussion
and Analysis of Financial Condition and Results of Operations," contains
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995 concerning, among other things, the prospects,
developments and business strategies for the Company and its operations,
including the development and marketing of certain new products and the
anticipated future growth in certain markets in which the Company currently
markets and sells its products or anticipates selling and marketing its products
in the future. These forward-looking statements (i) are identified by their



                                      -8-







use of such terms and phrases as "expected," "expects," "believe," "believes,"
"will," "anticipated," "emerging," "intends," "plans," "could," "may,"
"estimates," "should," "objective," and "goals" and (ii) are subject to risks
and uncertainties and represent the Company's present expectations or beliefs
concerning future events. The Company cautions that the forward-looking
statements are qualified by important factors that could cause actual results to
differ materially from those in the forward-looking statements, including (a)
risks of general market conditions, including demand for the Company's products
and services, competition and price levels and the Company's historical
dependence on relatively few products, certain suppliers and certain key
customers, and (b) risks inherent to the computer and network security industry,
including rapidly changing technology, evolving industry standards, increasing
numbers of patent infringement claims, changes in customer requirements, price
competitive bidding, changing government regulations and potential competition
from more established firms and others. Therefore, results actually achieved may
differ materially from expected results included in, or implied by these
statements.

COMPARISON OF THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2002 AND SEPTEMBER 30,
2001

     The following discussion and analysis should be read in conjunction with
the Company's Consolidated Financial Statements for the three and nine months
ended September 30, 2002 and 2001.

Revenues

     Revenues for the three months ended September 30, 2002 were $5,127,000, an
increase of $339,000, or 7%, as compared to the three months ended September 30,
2001. The increase is primarily due to increased sales to the Corporate Network
Access market through VASCO's reseller channel. Geographically, 15% of revenues
in the third quarter of 2002 were from the U.S. with 85% from outside the U.S.,
primarily Europe and Asia Pacific. In the third quarter of 2001, 12% of revenues
were from the U.S. with 88% from outside the U.S., primarily Europe.

     For the nine months ended September 30, 2002, revenues were $15,310,000, a
decrease of $5,386,000, or 26%, as compared to the same period last year. The
decline is primarily a result of the challenging sales environment in the
Company's banking segment and the reduction in new sales of VACMAN Enterprise
partially offset by increased sales to the Corporate Network Access market.
Customers in the Company's banking segment continue to delay purchase decisions.
The decline in new sales of the VACMAN Enterprise (also known as SnareWorks and
which provides security for large enterprises using mainframe and client-server
applications) is a direct result of the decreased investment in sales and
marketing expenses targeted to this customer segment. Even though sales in the
Corporate Network Access market are higher than the prior year, sales into this
market has been affected by the overall reduction in spending on technology.
Geographically, 15% of revenues for the nine months ended September 30, 2002
were from the U.S. with 85% from outside the U.S. For the nine months ended
September 30, 2001, 25% of revenues were from the U.S. with 75% from outside the
U.S.

Cost of Goods Sold

     Cost of goods sold for the three months ended September 30, 2002 was
$2,067,000, a decrease of $281,000, or 12%, as compared to the three months
ended September 30, 2001. The improvement reflected lower costs in the Digipass
product line.

     For the nine months ended September 30, 2002, cost of goods sold was
$5,942,000, a decrease of $2,105,000 or 26%, as compared to the same period last
year. The decline in cost of goods sold was directly related to the reduction in
revenues.

Gross Profit

     The Company's gross profit for the three months ended September 30, 2002
was $3,060,000 an increase of $620,000 or 25%, as compared to the three months
ended September 30, 2001. Gross profit as a percentage of net revenue was 60%
for the quarter ended September 30, 2002, as compared to 51% for the same period
of 2001. The increase in gross profit in absolute dollars and as a percentage of
revenue reflected the increase in sales to the Corporate Network Access market,
which has a higher margin percentage than sales to the banking market, and the
overall reduction in Digipass costs.

     Gross profit for the nine months ended September 30, 2002, was $9,368,000,
a decrease of $3,281,000 or 26% compared to the same period last year. The
decline in gross profit is directly related to the reduction in net revenue. As
a percentage of net revenue, gross profit was approximately 61% in both years.
Gross profit as a percentage of net revenue remained constant as gross profit
from VACMAN Enterprise revenues has been offset by the increase in Corporate
Network Access as a percentage of total revenue, the increase in VACMAN Server
revenues and the lower cost of Digipass product.

Sales and Marketing Expenses

     Sales and marketing expenses for the three months ended September 30, 2002
were $1,835,000, a decrease of $1,817,000, or 50%, over the three months ended
September 30, 2001. The reduction of expense reflects the reduction in sales and
marketing headcount from 82 at September 30, 2001 to 49 at September 30, 2002.
The reduction in headcount is primarily related to the elimination of sales and
marketing activities related to the VACMAN Enterprise product line.
Additionally, reductions in advertising, public relations, and trade shows
contributed to this decline.


     For the nine months ended September 30, 2002, sales and marketing expenses
were $6,040,000, a decrease of $4,541,000, or 43% compared to 2001, for the same
reasons as outlined above.

Research and Development

     Research and development costs for the three months ended September 30,
2002 were $749,000, a decrease of $704,000, or 48%, as compared to the three
months ended September 30, 2001. The Company has consolidated its research and
development centers, reducing headcount from 45 to 19.

     For the nine months ended September 30, 2002, research and development
expenses totaled $2,328,000, a decrease of $2,121,000, or 48%, as compared to
the same period last year.

General and Administrative Expenses

     General and administrative expenses for the three months ended September
30, 2002 were $1,238,000, a decrease of $310,000, or 20%, compared to the three
months ended September 30, 2001. This decrease was principally due to headcount
reduction from 26 to 11. Also contributing to this decrease were reduced
depreciation and amortization expenses related to the assets written off at the
end of last year, and reduced costs to support a smaller world-wide
infrastructure.

     For the nine months ended September 30, 2002, general and administrative
expenses were $3,178,000, a decrease of $1,242,000, or 28% compared to the same
period last year primarily due to the aforementioned headcount reduction.

Interest Expense, Net

     Net interest expense for the three months ended September 30, 2002 was
$45,000, compared to net interest income of $558,000 for the same period in
2001. This change was due to a reduction of invested cash balances.

     For the nine months ended September 30, 2002, net interest expense was
$238,000, compared to net interest income of $766,000 for the same period last
year. This change was due primarily to a reduction of invested cash balances.


                                      -10-







Other Expense, Net

     Other expense, net for the three months ended September 30, 2002 was
$71,000 compared to other income of $62,000 for the same period in 2001. The
change was due primarily to changes in exchange rates.

For the nine months ended September 30, 2002, other expense, net was $116,000,
compared to other income, net of $135,000 for the same period last year. The
change was due primarily to changes in exchange rates.

Income Taxes

     No income tax expense or benefit was recorded for the three months ended
September 30, 2002. No benefit was recorded to offset the pretax loss as
realization of the benefit from the additional loss is not assured. Income tax
expense of $140,000 for the nine months ended September 30, 2002 is composed of
$57,000 related to foreign operations and $83,000 related to the write-off of a
deferred tax asset in the United States.

Income tax expense of $176,000 and $369,000 for the three and nine months ended
September 30, 2001, respectively, relate to foreign operations.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash and cash equivalents were $2,738,000 at September 30,
2002, which is a decrease of approximately $3,604,000 from $6,342,000 at
December 31, 2001. As of September 30, 2002, the Company had working capital of
$4,612,000 compared with $6,661,000 at December 31, 2001.

     The Company has an overdraft agreement with a European bank pursuant to
which the bank will provide funding in a maximum amount equal to 80% of VASCO's
Belgium subsidiary's defined receivables. As of September 30, 2002,
approximately $1,960,000 was available under that agreement. The agreement does
not have a fixed term and can be terminated by the bank without cause with 30
days notice. Should the Company continue to operate at a loss, the bank could
terminate the agreement and, as a result, the Company would need to obtain
additional financing. There is no assurance that such financing would be
available. Additionally, the Company continues to evaluate its options to reduce
expenses by consolidating operations where efficiencies can be gained and
eliminating expenses related to non-essential activities.

     The Company's term loan of $3.4 million due September 30, 2003, will be
classified as a current liability in the fourth quarter of 2002.

     Capital expenditures during the first nine months of 2002 were $415,000 and
consisted primarily of computer equipment and office furniture and fixtures.

     For the three months ended September 30, 2002, the Company recorded an
operating loss before non-cash recovery for stock options granted to certain
officers of the Company of $762,000 and a net loss before these option grants of
$878,000. The Company had a loss before non-cash recovery, interest, taxes
depreciation and amortization of $514,000.

     For the nine months ended September 30, 2002, the Company recorded an
operating loss before non-cash recovery for stock options granted to certain
officers of the Company of $2,178,000 and a net loss before these option grants
of $2,672,000. The Company has a loss before non-cash recovery, interest, taxes,
depreciation and amortization of $1,258,000.

     The Company may seek acquisitions of businesses, products and technologies
that are complementary or additive to those of the Company. While from time to
time the Company engages in discussions with respect to potential acquisitions,
there can be no assurance that any such acquisitions will be made.



                                      -11-





     In July 2002, the Company was notified that effective November 1, 2002, The
Nasdaq Stock Market, Inc. would be implementing its new minimum stockholders'
equity requirement of $10,000,000 for continued listing on the Nasdaq National
Market. The notification further stated that the Company's current shareholders'
balance was not adequate to meet the new standard and indicated that the Company
would receive a formal written notification of a deficiency if public filings
after November 1, 2002 did not reflect the new minimum standard. At the present
time, the Company's stockholders' equity balance does not meet the new standard
and the Company expects to receive a notice of deficiency from The Nasdaq Stock
Market, Inc. Once the notice is received, the Company expects that it will make
application for a transfer of the listing to the Nasdaq SmallCap Market.

the Company's Annual Report on Form 10-K for the fiscal year ended December 31,

ITEM 4. DISCLOSURE CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains a system of disclosure controls and procedures that is
designed to ensure that information required to be disclosed by the Company in
this Form 10-Q, and in other reports required to be filed under the Securities
Exchange Act of 1934, is recorded, processed, summarized and reported within the
time periods specified in the rules and forms for such filings. Management of
the Company, under the direction of the Company's Chief Executive Officer and
Chief Financial Officer, reviewed and performed an evaluation of the
effectiveness of the Company's disclosure controls and procedures within 90 days
prior to filing this quarterly report (the "Evaluation Date"). Based on that
review and evaluation, the Chief Executive Officer and Chief Financial Officer,
along with other key management of the Company, have determined that the
disclosure controls and procedures were and are effective as designed to ensure
that material information relating to the Company and its consolidated
subsidiaries would be made known to them on a timely basis.

Changes in Internal Controls

There were no significant changes in the Company's internal controls or other
factors that could significantly affect these controls subsequent to the
Evaluation Date.

                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

         On March 13, 2002, a suit was filed by ActivCard, S.A., against the
Company in the United States District Court, District of Delaware, claiming
