         As of October 31, 2003, 30,425,284 shares of the Company's Common
Stock, $.001 par value per share ("Common Stock"), were outstanding.

EXPLANATORY NOTE:
The Company has restated its Consolidated Statements of Operations for the
three- and nine-month periods ended September 30, 2003 to reflect a beneficial
conversion feature of $3,720,000 related to the issuance of Series D Convertible
Preferred Stock, in accordance with Emerging Issues Task Force (EITF) No. 98-5,
"Accounting for Convertible Securities with Beneficial Conversion Features or
Contingently Adjustable Conversion Ratios." The beneficial conversion feature
represents the difference in the proceeds from the issuance of the preferred
stock and the value of the common stock it was immediately convertible into,
based upon the market value of the common stock on the date of issuance. The
beneficial conversion feature is analogous to a dividend and is recognized as a
return to the preferred shareholders.





The effect of the restatement was to reduce net income (loss) available to
common shareholders by $3,720,000; reduce basic and diluted income (loss) per
common share from $0.04 per share to ($0.08) per share for the three months
ended September 30, 2003 and from $0.06 per share to ($0.06) per share for the
nine months ended September 30, 2003; and reduce basic and diluted loss from
continuing operations from ($0.01) per share to ($0.13) per share for the three
months ended September 30, 2003 and from $0.00 per share to ($0.13) per share
for the nine months ended September 30, 2003.

The restatement had no impact on the Consolidated Balance Sheet as of September
30, 2003, or on the Consolidated Statements of Comprehensive Income (Loss) and
the Consolidated Statements of Cash Flows for the nine-month period ended
September 30, 2003.

STOCK-BASED COMPENSATION

         At September 30, 2003, the Company had a stock-based employee
compensation plan. The Company accounts for the plan using the intrinsic method
under the recognition and measurement principles of APB Opinion No. 25,
"Accounting for Stock Issued to Employees", and related Interpretations. No
stock-based compensation is reflected in net income, as all options granted to
employees under the plan had an exercise price equal to the market value of the
underlying Common Stock on the date of grant. The following table illustrates
the effect on net income (loss) and earnings per share if the Company had
applied the fair value recognition provisions of FASB Statement No. 123,
"Accounting for Stock-Based Compensation", to stock-based employee compensation.

NOTE 2 - RESTATEMENT

         The Company has restated its Consolidated Financial Statements for the
three- and nine-month periods ended September 30, 2003 to reflect a beneficial
conversion feature of $3,720,000 related to the issuance of its Series D
Convertible Preferred Stock in accordance with Emerging Task Force (EITF) No.
98-5, "Accounting for Convertible Securities with Beneficial Conversion Features
or Contingently Adjustable Conversion Ratios." The beneficial conversion feature
represents the difference in the proceeds from the issuance of the preferred
stock and the value of the Company's common stock it was immediately convertible
into, based upon the market value of the common stock on the date of issuance.
The beneficial conversion feature is analogous to a dividend and is recognized
as a return to the preferred shareholders.

         The effect of the restatement is to reduce net income (loss) available
to common shareholders, basic and diluted loss per share and basic and diluted
loss from continuing operations for the three- and nine-month periods ended
September 30, 2003. The restatement had no impact on our Consolidated Balance
Sheets as of December 31, 2002 and September 30, 2003. This restatement also had
no impact on our Consolidated Statements of Comprehensive Income (Loss) or our
Consolidated Statements of Cash Flow for the nine-month period ended September
30, 2003.

The restatement had the following impact to our Consolidated Statements of
Operations:

NOTE 4 - DISCONTINUED OPERATIONS

         On July 8, 2003, effective as of July 1, 2003, VASCO sold its VACMAN
Enterprise ("VME") business, originally known as Intellisoft and/or Snareworks,
to SecureD Services, Inc. (SSI). Under the terms of the agreement, VASCO
received a senior secured promissory note with a face value of approximately
$1.1 million, valued at $1.0 million by an independent valuation firm, and $2
million of Convertible Preferred Stock from SSI, valued at $0.6 million by an
independent valuation firm, in exchange for the VACMAN Enterprise assets. The
promissory note bears a 6% interest rate and is payable in 36 equal and
consecutive monthly payments. The Preferred Stock includes a 6% cumulative stock
dividend, payable quarterly, and can be converted into SSI's common stock at
defined intervals beginning July 1, 2005. In accordance with Statement of
Financial Accounting Standard (SFAS) No. 144 "Accounting for the Impairment or
Disposal of Long-Lived Assets", the assets and liabilities of this business unit
have been disaggregated from the operational assets and liabilities of the
Company. The results of the operations of VME for the three- and nine-month

NOTE 5 - STOCKHOLDERS' EQUITY

         On July 15, 2003, the Company reached an agreement with Ubizen N.V.
("Ubizen") whereby VASCO purchased and redeemed all of the VASCO Series C
Convertible Preferred Stock (the "Series C Preferred Stock") and Common Stock
Purchase Warrants owned by Ubizen. Under the terms of the Purchase Agreement,
the Company paid $3 million to Ubizen and issued 2 million shares of the
Company's Common Stock on July 25, 2003. Using the closing price of the
Company's Common Stock on July 25, 2003, the value of the stock issued was
$4,000,000. An additional $1 million will be paid to Ubizen on or before
November 14, 2003. The Common Stock issued by the Company is subject to a
lock-up period wherein the lock-up will expire in increments of 500,000 shares
each on October 15, 2003, January 15, 2004, April 15, 2004 and July 15, 2004.
Once the lock-up expires, the shares will be subject to volume trading
restrictions through January 1, 2005.

         On September 11, 2003, the Company sold 800 shares of its Series D 5%
Cumulative Convertible Voting Preferred Stock (the "Series D Preferred Stock")
and 600,000 warrants to purchase Common Stock. The Series D Preferred Stock
carries a 5% dividend, is convertible into 4 million shares of Common Stock at a
fixed price of $2.00 per share and will vote with the Common Stock as a class on
matters presented to the stockholders. The implied value of the Series D
Preferred Stock was $5,714,000, calculated based upon the annual dividend rate
divided by a required rate of return. The warrants are exercisable, over a
five-year period, at $3.47 per share and were valued at $1,455,000 using the
Black-Scholes pricing model. Of the net proceeds from the sale, $5,831,000 was
allocated to the Series D Preferred Stock and $1,485,000 was allocated to the
warrants based upon their relative fair values. In addition, a beneficial
conversion value was calculated for the Series D Preferred Stock as the
difference between the price of the Company's Common Stock at the transaction
date and the conversion price of the Series D Preferred Stock. The amount of the
beneficial conversion, $3,720,000, is analogous to a dividend and was recorded
to retained earnings.

         During the third quarter of 2003, the Company issued 25,625 shares of
Common Stock as a result of the exercise of options under the Company's stock
option plan generating total proceeds of $48,082.
