2 SHARE PURCHASE AGREEMENT THIS SHARE PURCHASE AGREEMENT (this "Agreement") is made and entered into as of the 29th day of March, 2001, by and among the persons and entities listed on Exhibit A hereto and identified as Sellers (sometimes referred to herein individually as a "Seller" and collectively as, "Sellers"), VASCO Data Security, Inc., a Delaware corporation ("Buyer"), VASCO Data Security International, Inc., a Delaware corporation and parent of Buyer ("Parent"), and, for purposes of consenting to the transactions contemplated hereunder, making the representations and warranties contained in Section 4 hereof and agreeing to certain covenants herein, Identikey Limited, a company registered under the Corporations Law of Queensland, Australia (ACN 092 888 910) (the "Company"). Recitals: A. Sellers own 100,500,000 ordinary shares (the "Ordinary Shares"), of the Company (the 100,500,000 Ordinary Shares owned by Sellers are referred to herein as the "Sale Shares"). B. The Sale Shares represent 90.2247% of the issued and outstanding securities of the Company. C. Buyer desires to purchase from Sellers, on the terms and conditions hereinafter set forth, all of the Sale Shares. D. Sellers desire to sell all of the Sale Shares to Buyer for the consideration, and on the terms and conditions, hereinafter set forth. E. It is the intention of Buyer to acquire from the Company's minority shareholders (the "Minority Shareholders") the remaining 9.7753% of the Company's issued and outstanding Ordinary Shares (the "Minority Shares"), in a manner to be determined by Buyer. NOW, THEREFORE, in consideration of the foregoing recitals, and of the respective covenants, representations, and agreements herein contained, the sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 1. PURCHASE AND SALE OF SALE SHARES; CLOSING. 1.1 PURCHASE AND SALE OF SALE SHARES. Sellers, in reliance on the representations, warranties, and covenants of Buyer contained herein and subject to the terms and conditions of this Agreement, hereby agree to sell to Buyer all of the Sale Shares which they own for the Purchase Consideration set forth in Section 2 below; and Buyer, in reliance on the representations, warranties, and covenants of Sellers contained herein and subject to the terms and conditions of this Agreement, hereby agrees to purchase from Sellers, the Sale Shares for the Purchase Consideration set forth in Section 2 below. Buyer shall pay any stamp duty assessed by the State of Queensland, Australia in -1-

3 connection with the transfer of the Sale Shares to Sellers. Any other fees, charges or taxes due and payable in connection with the delivery and transfer of the Sale Shares shall be paid by Sellers. 1.2 CLOSING. The purchase and sale of the Sale Shares (the "Closing") provided for in this Agreement will take place at the offices of Piper Marbury Rudnick & Wolfe LLP, 1200 19th Street, N.W., Washington, D.C., at 10:00 a.m. (local time) within five business days after the satisfaction of all conditions specified in Sections 9 and 10 hereof (the "Closing Date"), or at such other time and place as the parties may agree. In lieu of an in-person Closing, the Closing may take place via teleconference link and facsimile exchange of all documents required to be delivered pursuant to Section 3 hereof. 2. CONSIDERATION FOR SALE SHARES. In consideration of the transfer, sale and delivery of the Sale Shares to Buyer as provided hereunder, Buyer will deliver and issue to Sellers the following (collectively, the "Purchase Consideration"): 2.1 CLOSING CONSIDERATION. At Closing: (i) Sellers shall be entitled to receive, subject to Section 2.2(c), an aggregate of 366,913 shares of the common stock, par value $0.001 per share (the "Common Stock") of Parent (the "Closing Payment") and (ii) Buyer shall deliver to each Seller a stock certificate representing that portion of the Closing Payment that is payable to such Seller. The Closing Payment shall be apportioned among Sellers on a pro rata basis as specified on Exhibit A hereto. The shares of Common Stock to be issued as Purchase Consideration shall be in the form of unregistered shares of Common Stock and shall be free and clear of all liens, claims, charges, encumbrances, security interests, pledges or other claims. 2.2 POST-CLOSING ADJUSTMENT. (a) The parties agree that the amount of the Closing Payment was determined as if the Company's tangible stockholders' equity was going to be AUD$245,164 on the Closing Date. Accordingly, the parties agree that the amount of the Closing Payment shall be adjusted (the "Adjustment") in the event that the Company's actual tangible stockholders' equity on the Closing Date, as shown on the audited balance sheet to be prepared in accordance with Section 2.2(b) below, is less than AUD$245,164. If the tangible stockholders' equity so reflected is less than AUD$245,164 on the Closing Date, then the amount of the Closing Payment shall be decreased by one U.S. dollar (U.S.$1.00) for each Australian dollar (AUD$1.00) by which the Company's actual tangible stockholders' equity is below AUD$245,164. For purposes of this Agreement, "tangible stockholders' equity," shall mean the total assets of the Company less intangible assets and total liabilities, all determined in accordance with the Accounting Standards (as defined in Section 4.4 below). (b) For purposes of effecting the Adjustment, if any, pursuant to Section 2.2(a), within ninety days following the Closing Date, Sellers (as defined in Section 4 below) shall cause to be prepared and delivered to Buyer an audited balance sheet of the Company as at the Closing Date, along with Sellers' calculation of tangible stockholders' equity as at the Closing Date (the "Equity Statement"). If within fifteen days following delivery of the Equity Statement, the Buyer has not given Sellers notice of its objection to the Equity Statement (such notice must contain a statement -2-

4 of the basis of the Buyer's objection), then the Equity Statement shall be deemed accepted by Buyer and will be used to compute the Adjustment hereunder. If the Buyer gives such notice of objection as to the calculation of "tangible stockholders' equity," the parties will have thirty days to resolve the dispute among themselves. If the parties have not resolved such dispute within such thirty-day period, then the parties shall mutually select an independent expert from one of the "big-five" accounting firms in Australia who shall decide the dispute within thirty days after being selected. If the parties cannot agree on an independent expert, then the independent expert shall be selected by the President of the Institute of Chartered Accountants in Australia. The parties hereto each agree to be bound by the decision of the independent expert in the absence of manifest error. All costs of the independent expert in connection with this Section 2.2 shall be split equally between Sellers and Buyer. (c) At Closing, Buyer shall retain 40,667 shares (the "Retained Shares") of Common Stock from the Closing Payment for purposes of satisfying any Adjustment liability under this Section 2.2. Within ten days after the final determination of "tangible stockholders' equity" and determination of the amount of the Adjustment, if any, Buyer shall retain that portion of the Retained Shares necessary to satisfy the Adjustment and thereafter release to Sellers the remaining number of Retained Shares. For purposes of determining the number of Retained Shares, if any, that Buyer is entitled to retain as a result of the Adjustment, the per share value of the Common Stock will be deemed to be $7.50. 2.3 EARN-OUT. (a) In addition to the Closing Payment, Sellers shall be entitled to receive additional consideration (the "Earn Out Payment") for the sale of the Sale Shares as follows: to the extent that, during the 15-month period commencing February 1, 2001 and ending April 30, 2002 (the "Earn Out Period"), the Net Revenues (as defined below) from the sale of the Company's Products (as defined below) exceeds U.S. $3,050,000 (the "Threshold"), Sellers shall receive additional shares of Common Stock with an aggregate value equal to the product of (i) 90.2247% multiplied by (ii) six times the amount by which Net Revenues from the sale of the Company's Products exceeds the Threshold, provided that the maximum additional consideration that can be earned pursuant to this Section 2.3 is U.S. $11,503,649. For purposes of determining the number of shares of Common Stock, if any, to which Sellers are entitled as a result of the Earn Out Payment, the per share value of the Common Stock will be deemed to be the greater of (x) eighty percent (80%) of the average closing price of Buyer's Common Stock on the Nasdaq National Market for the ten trading days prior to the expiration of the Earn Out Period, or (y) $7.50. Any Earn Out Payment made pursuant to this Section 2.3 shall be apportioned among Sellers and in the manner specified on Exhibit B hereto. In connection with Buyer's acquisition of the Minority Shares, unless agreed otherwise between Buyer and the Minority Shareholders, it is the present intention of Buyer to issue to the Minority Shareholders an earn out payment comprised of additional shares of Common Stock with an aggregate value equal to the product of (i) 9.7753% multiplied by (ii) six times the amount by which Net Revenues from the sale of the Company's Products exceeds the Threshold, provided that the maximum additional consideration that can be earned by the Minority Shareholders is, in the aggregate, U.S. $1,246,351. For purposes of this Section 2.3; (i) "Net Revenues" shall mean revenues derived from sales of Company's Products, less all amounts due to resellers of the -3-

5 Company's Products in connection with such sales, and (ii) "Company's Products" shall mean products sold by Buyer or the Company (or any entity related to Buyer or the Company) that are substantially based on source codes developed by employees of the Company, even if such employees are employed by Buyer (or any entity related to Buyer) after the Closing. (b) For purposes of effecting the Earn Out Payment, within sixty days following the end of the Earn Out Period, Buyer will cause its Chief Financial Officer to prepare and deliver to Sellers a statement reflecting Buyer's calculation of the Net Revenues from the sale of Company's Products during the Earn Out Period (the "Revenue Statement"). If within fifteen days following delivery of the Revenue Statement, Sellers have not given Buyer notice of their objection to the Revenue Statement (such notice must contain a statement of the basis of Sellers' objection), then the Revenue Statement shall be deemed accepted by all Sellers and will be used to compute the Earn Out Payment. If Sellers give such notice of objection as to the calculation of Net Revenues the parties will have thirty days to resolve the dispute among themselves. If the parties have not resolved such dispute within such thirty-day period, then the parties shall select an independent expert in the manner specified in Section 2.2(b) above who shall decide the dispute within thirty days after being selected. The parties hereto each agree to be bound by the decision of the independent expert in the absence of manifest error. All costs of the independent expert in connection with this Section 2.3 shall be split equally between Sellers and Buyer. (c) Buyer and Parent will use commercially reasonable efforts to promote and market the Company's Products, in accordance with prudent business practice (as determined by Buyer and Parent), during the Earn Out Period; provided, however, that nothing contained in this Section 2.3(c) shall obligate Buyer or Parent to expend any minimum level of financial or other resources on promotion and marketing of the Company's Products. For each calendar quarter during the Earn Out Period, Buyer shall furnish to Sellers a report detailing the number and dollar amount of Company's Products sold by Buyer during such calendar quarter (each a "Quarterly Report"). Buyer shall deliver each Quarterly Report to Sellers within ten business days after the last day of the calendar quarter to which such Quarterly Report relates. 2.4 NO FRACTIONAL SHARES. No fractional shares of Common Stock shall be issued as Purchase Consideration hereunder. In lieu of any fractional shares to which any Seller would be entitled, Parent will pay to such Seller cash equal to the product of such fraction multiplied by (i) with respect to the Closing Payment, $7.50, or (ii) with respect to the Earn Out Payment, the fair market value of one share of Parent's Common Stock as determined in accordance with Section 2.3(a) above. 3. DELIVERIES AT CLOSING. 3.1 DELIVERIES OF SELLERS. At Closing, Sellers shall deliver, or cause to be delivered, to Buyer the following: (a) certificates representing the Sale Shares in negotiable form, duly endorsed in blank to Buyer or accompanied by appropriate share powers, free and clear of all liens, claims, charges, encumbrances, security interests, pledges or other claims of every kind; -4-

The tax returns of the Company have not been reviewed or audited by any federal, state, county, local or other taxing authority.

Neither the execution and delivery of this Agreement by Seller, nor the consummation of the transactions contemplated hereby, will contravene or violate any regulation or court order which is applicable to Seller, or will result in a default under, or require the consent or approval of any party to, any contract relating to Seller or to which Seller is a party or otherwise bound or affected, or require Seller to notify or obtain any license or consent from any federal, state, local or other court or governmental agency or body or from any other regulatory authority. 5.3 REGULATORY CONSENTS AND APPROVALS.

HOLDER AGREES THAT ANY HEDGING TRANSACTIONS INVOLVING THE SECURITIES WILL BE CONDUCTED IN COMPLIANCE WITH THE ACT AND AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

Buyer is duly qualified or licensed as a foreign corporation to do business and is in good standing in each jurisdiction in which the character of properties occupied, owned or held under lease by Buyer, or the nature of the business conducted by the Buyer, makes such qualification or license necessary, except where the failure to be so qualified or licensed would not have a Material Adverse Effect on the business, operations, assets, liabilities or financial condition of Buyer and its subsidiaries taken as a whole. 6.2 VALID ISSUANCE. The Common Stock, when issued and paid for in accordance with this Agreement, will be duly authorized, validly issued, fully paid and nonassessable and (assuming the accuracy of Sellers' representation set forth in Section 5.5 hereof) issued in compliance with all applicable U.S. securities laws and will not be subject to any preemptive or other similar rights. 6.3 AUTHORITY.

The execution and delivery by Buyer and Parent of this Agreement does not, and the sale and issuance of the Common Stock and consummation of the other transactions contemplated by this Agreement will not, conflict with, or result in any violation or breach of any provision of, the charter or bylaws of Buyer or Parent, as the case may be. 6.5 REQUIRED FILINGS AND CONSENTS. No consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality is required by or with respect to Buyer -18-

The activities described in this Section 7.5(a) shall be referred to as "Sellers' Negotiations." -20-

22 (b) If the Closing does not occur, and such failure is due to a breach by any Seller of Section 7.5(a) above, then Seller shall promptly (and in any event within two days of receipt of written notice from Buyer) pay to Buyer by wire transfer of immediately available funds to an account or accounts designated by Buyer (i) a break-up fee of U.S.$1,000,000, plus (ii) all actual out-of-pocket expenses (including all fees and expenses of Buyer's counsel, advisors, accountants and consultants) incurred by Buyer or on its behalf in connection with the transactions contemplated by this Agreement (the payments due under subsections (i) and (ii) hereof shall collectively be referred to herein as the "Break-Up Fee"). The Break-Up Fee shall be Buyer's sole remedy in the event of a breach by Seller of Section 7.5(a) above; provided, however, that neither the exercise of nor the failure to exercise Buyer's right to payment under this Section 7.5(b) will limit Buyer in any manner in the enforcement of any other remedies available to it in the event of a breach by any Seller of any other provision of this Agreement.

Each party's right of termination under Section 11.1 is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of a right of termination will not be an election of remedies. If this Agreement is terminated pursuant to Section 11.1, all further obligations of the parties under this Agreement will terminate; provided, however, that if this Agreement is terminated by a party because of the breach of the Agreement by the other party or because one or more of the conditions to the terminating party's obligations under this Agreement is not satisfied as a result of the other party's failure to comply with its obligations under this Agreement, the terminating party's right to pursue all legal remedies will survive such termination unimpaired. 12. INDEMNIFICATION. 12.1 Sellers shall, jointly and severally, indemnify and hold harmless Buyer as to the following matters: (a) any and all damages, losses, deficiencies, liabilities, costs and expenses resulting from, relating to or arising out of any breach of representation or warranty, non-fulfillment of any agreement or covenant, omission or misrepresentation by the Company or Sellers hereunder; (b) any and all claims, demands, causes of action or proceeding against the Company, whether arising before or after the date hereof, but relating to facts, events or circumstances in existence or occurring on or prior to the date hereof, except to the extent disclosed in this Agreement; and (c) any and all actions, suits, proceedings, demands, judgments, costs, and related legal expenses reasonably incurred, incident to any of the foregoing or to enforce this Section 12.1. Each Seller, individually, shall indemnify and hold harmless Buyer as to any and all damages, losses, deficiencies, liabilities, costs and expenses resulting from, relating to or arising out of any breach of a representation or warranty made by such Seller individually in Section 5 above. 12.2 Buyer shall indemnify and hold harmless Sellers as to the following matters: (a) any and all damages, losses, deficiencies, liabilities, costs and expenses resulting from, relating to or arising out of any breach of representation or warranty, non-fulfillment of any agreement or covenant, omission or misrepresentation hereunder; and (b) any and all actions, suits, proceedings, demands, judgments, costs, and related legal expenses reasonably incurred, incident to any of the foregoing or to enforce this Section 12. 12.3 With respect to indemnification hereunder relating to third party claims, promptly after receipt by an indemnified party under Section 12.1 or 12.2 of notice of the commencement of any proceeding against it, such indemnified party will, if a claim is to be made -25-

27 against an indemnifying party under such section, give notice to the indemnifying party of the commencement of such claim, but the failure to notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party demonstrates that the defense of such action is prejudiced by the indemnifying party's failure to give such notice. If any such proceeding is brought against an indemnified party and it gives notice to the indemnifying party of the commencement of such proceeding, the indemnifying party will be entitled to participate in such proceeding and, to the extent that it wishes (unless (i) the indemnifying party is also a party to such proceeding and the indemnified party determines in good faith that joint representation would be inappropriate, or (ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to defend such proceeding and provide indemnification with respect to such proceeding), to assume the defense of such proceeding with counsel satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under this Section 12 for any fees of other counsel or any other expenses with respect to the defense of such proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such proceeding, other than reasonable costs of investigation. If the indemnifying party assumes the defense of a proceeding: (a) it will be conclusively established for purposes of this Agreement that the claims made in that proceeding are within the scope of and subject to indemnification; (b) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party's consent unless (i) there is no finding or admission of any violation of any legal requirements or any violation of the rights of any person or entity and no effect on any other claims that may be made against the indemnified party, and (ii) the sole relief provided is monetary damages that are paid in full by the indemnifying party; and (c) the indemnified party will have no liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to an indemnifying party of the commencement of any proceeding and the indemnifying party does not, within fifteen (15) days after the indemnified party's notice is given, give notice to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will be bound by any determination made in such proceeding or any compromise or settlement effected by the indemnified party. Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such proceeding, but the indemnifying party will not be bound by any determination of a proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld). Sellers hereby consent to the non-exclusive jurisdiction of any court in which a proceeding is brought against any indemnified party for purposes of any claim that an indemnified party may have under this Agreement with respect to such proceeding or the matters alleged therein, and agree that process may be served on Sellers with respect to such a claim anywhere in the world. 12.4 A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought. -26-

28 12.5 Notwithstanding any other provision of this Agreement, the total sums to be paid by an indemnifying party pursuant to the indemnification obligations under this Agreement shall not, in the aggregate, exceed: (a) if the indemnifying party is a Seller, the amount of the Purchase Consideration received by such Seller; or (b) if the indemnifying party is Buyer, the Purchase Consideration. 12.6 Upon notice to Sellers specifying in reasonable detail the basis for such set-off, Buyer may set off any amount to which it may be entitled under this Section 12 against consideration otherwise payable to Sellers pursuant to Section 2.3. The exercise of such right of set-off by Buyer in good faith, whether or not ultimately determined to be justified, will not constitute an event of default hereunder. Neither the exercise of nor the failure to exercise such right of set-off will constitute an election of remedies or limit Buyer in any manner in the enforcement of any other remedies that may be available to it. 13. POST-CLOSING COVENANTS. 13.1 To the extent that Buyer has not acquired 100% of the issued and outstanding shares of the Company at Closing, Mark G. Kefford shall use his best efforts to cause all of the Minority Shareholders to sell all of the Ordinary Shares owned by such Minority Shareholders to Buyer, in any lawful manner of sale deemed desirable by Buyer, such that Buyer shall own 100% of the Company within 30 days following the Closing. 13.2 Following Closing, each of the parties hereto agrees that it will keep confidential and will not use, disclose or divulge, the terms and conditions of this Agreement and the transactions contemplated hereby; provided, however, that each party may disclose such matters as required by law or by the rules or regulations of any stock exchange applicable to such party, and such matters as are required to be disclosed in connection with consummating all of the transactions and actions contemplated by this Agreement. Notwithstanding the foregoing, Buyer may issue a press release (or releases) regarding the transactions contemplated hereby, the content of which must be approved in advance by Sellers, which approval shall not be unreasonably withheld. 13.3 Within ninety days following the determination of the amount of the Earn Out Payment, if any, payable by Buyer to Sellers, Parent shall file a registration statement on either Form S-3 or such other appropriate form, the choice of which will be at Parent's sole election, with the Securities and Exchange Commission for resale of the Common Stock under the Securities Act and use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable following such filing. 14. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. (a) All representations, indemnifications, warranties, and agreements made by Buyer and Sellers in this Agreement or pursuant hereto shall survive the date of this Agreement. -27-

29 (b) Notwithstanding any investigation or audit conducted before or after the date hereof, the parties shall be entitled to rely upon the representations and warranties set forth in this Agreement. 15. EXPENSES. Each of Sellers and Buyer shall pay their own respective expenses incurred in connection with the consummation of the transactions contemplated by this Agreement, including, without limitation, legal and accounting fees and expenses, and the fees and expenses of any investment banker or financial advisor engaged in connection with the sale of the Sale Shares. 16. FURTHER ACTIONS AND ASSURANCES. Sellers and Buyer shall execute and deliver any and all documents, and shall cause any and all other action to be taken after the date hereof, which may be necessary or proper to effect or evidence the provisions of this Agreement and the transactions contemplated hereby. 17. COUNTERPARTS. This Agreement may be executed in several counterparts each of which is an original and any Seller may become a party hereto by executing a counterpart hereof. This Agreement and any counterpart so executed shall be deemed to be one and the same instrument. 18. CONTENTS OF AGREEMENT; PARTIES IN INTEREST.

This Agreement may not be amended except by a writing executed by the party to be charged with the amendment.

2 [VASCO LOGO] NEWS RELEASE VASCO Acquires Global Web Security Software Company Identikey Ltd. Addition of new web security software products and experienced software engineers expected to speed VASCO's entry into new markets and accelerate revenue growth OAKBROOK TERRACE, Ill. and BRUSSELS, Belgium - April 4, 2001 - US-based VASCO Data Security International, Inc. (Nasdaq NM and Nasdaq Europe: VDSI; www.vasco.com), a global provider of security solutions that enable e-business and e-commerce, announced that it has acquired control of Identikey Ltd. (www.identikey.com), a privately held international security software company headquartered in Brisbane, Australia, with operations in the United States, Europe and Australia. The purchase price of approximately $2 million was paid in shares of VASCO Common Stock, with potential additional earnout payments based on defined performance incentives. VASCO expects the acquisition to be neutral to its earnings per share for the 12 months following the acquisition, and significantly accretive after that period. VASCO has acquired Identikey to increase its market share and revenues in the rapidly growing web security marketplace, to expand its product line for securing web-based applications, and to enhance its ability to deliver market-driven security software products. VASCO plans to announce its first new products from the acquisition of Identikey under its SnareWorks family of products during 2001. "We were able to close the Identikey acquisition in due course thanks in large part to the longstanding and mutually productive partnership between our two companies," noted Mario Houthooft, President and CEO of VASCO. "As a result, VASCO is now in a better position than ever to provide web portal and web-based application security to our customers worldwide. We will soon introduce innovative security software, based on the Identikey platform, that will enable any corporation, financial institution, and government agency to secure their e-business and e-commerce initiatives, easily and affordably." Mark Kefford, previously CEO of Identikey and now a member of the VASCO management team, concurred. "Our family of web security software products complements VASCO's expertise in strong authentication and enterprise-wide security, and will allow us to become what we believe will be the security platform of choice for supporting business initiatives, reaching from the mainframe to the web with equal ease." # # # About VASCO VASCO secures the enterprise from the mainframe to the Internet with infrastructure solutions that enable secure e-business and e-commerce, protect sensitive information, and safeguard the identity of users. The Company's family of Digipass(R) and SnareWorks(R) products offers end-to-end security through strong authentication and digital signature, true Single Sign-On, access control and advanced entitlements, web portal security, and PKI enablement, while sharply reducing the time and effort required to deploy and manage security. VASCO's customers
