At the Effective Time, by virtue of the Merger and without any action on the part of VMARK or UNIDATA or the holders of any securities issued by either of them: (a) Conversion of UNIDATA Common Stock. Each share (a "Share") of UNIDATA's Class A common stock, no par value (the "UNIDATA Class A Common Stock") and Class B Common Stock, no par value (the "UNIDATA Class B Common Stock" and together with the UNIDATA Class A Common Stock, the "UNIDATA Common Stock"), issued and outstanding immediately prior to the Effective Time (excluding any Shares to be canceled pursuant to Section 1.06(b) and any Dissenting Shares, as defined in Section 1.09) shall be converted, subject to Sections 1.06(d) and 1.07(f) and (g), into the right to receive 0.44765 shares (the "Exchange Ratio") of validly issued, fully paid and nonassessable shares of VMARK common stock, $.01 par value per share ("VMARK Common Stock") and a pro rata right under the VMARK Rights Plan (as defined Section 3.29). (b) Cancellation of UNIDATA Common Stock. Each Share held in the treasury of UNIDATA and each Share owned by any direct or indirect subsidiary of UNIDATA immediately prior to the Effective Time (the "Cancelled Shares") shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding and be canceled and retired without payment of any consideration therefor. (c) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to reflect fully the effect of any subdivision, combination, stock dividend (including any dividend or distribution of securities convertible into VMARK Common Stock or UNIDATA Common Stock), reorganization, recapitalization or similar capital change with respect to VMARK Common Stock or UNIDATA Common Stock occurring after the date hereof and prior to the Effective Time, other than in connection with UNIDATA's consummation of the O2 Acquisition (as defined in Section 4.01). (d) Fractional Shares. No fraction of a share of VMARK Common Stock shall be issued, but in lieu thereof each holder of UNIDATA Common Stock who would otherwise be entitled to a fraction of a share of VMARK Common Stock (after aggregating all fractional shares of VMARK Common Stock to be received by such holder and providing for any amounts or shares to be withheld or delivered into escrow pursuant to Section 1.07(f) and (g), it being the intention of the parties that no holder of UNIDATA Common Stock will receive cash in an amount equal to or greater than the value of one full share of VMARK Common Stock) shall receive from VMARK an amount of cash (rounded to the nearest cent), without interest, equal to the product of (i) such fraction, multiplied by (ii) the closing price of VMARK Common Stock on the Nasdaq National Market on the date of the Effective Time. I-3 12 Section 1.07. Exchange of Certificates. (a) Exchange Agent. As of the Effective Time, VMARK shall supply, or shall cause to be supplied, to or for the account of a bank or trust company to be designated by VMARK (the "Exchange Agent"), in trust for the benefit of the holders of UNIDATA Common Stock (other than Dissenting Shares and Cancelled Shares), for exchange in accordance with this Section 1.07, certificates evidencing the VMARK Common Stock issuable pursuant to Section 1.06 in exchange for outstanding Shares and all cash required to be paid pursuant to Sections 1.06(d) and 1.07(c). (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, VMARK shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates (the "Certificates") which immediately prior to the Effective Time evidenced outstanding Shares, other than Dissenting Shares and Cancelled Shares, (i) a letter of transmittal, which letter shall specify, among other conditions, that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and (ii) instructions to effect the surrender of the Certificates in exchange for the certificates evidencing shares of VMARK Common Stock (the "VMARK Certificates") and, in lieu of any fractional shares thereof, cash. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and such other customary documents as may be reasonably required by VMARK or the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor (A) VMARK Certificates evidencing that whole number of shares of VMARK Common Stock which such holder has the right to receive in respect of the Shares formerly evidenced by such Certificate in accordance with the Exchange Ratio and the other applicable provisions hereof, together with an equal number of rights under the VMARK Shareholder Rights Plan, (B) any dividends or other distributions to which such holder is entitled pursuant to Section 1.07(c), and (C) cash in lieu of fractional VMARK Common Stock to which such holder is entitled pursuant to Section 1.06(d) (such VMARK Common Stock, rights, dividends, distributions and cash in lieu of fractional shares together with any amounts or shares to be withheld or delivered into escrow pursuant to Sections 1.07(f) and (g) being collectively referred to as the "Merger Consideration"), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Shares which is not registered in the transfer records of UNIDATA as of the Effective Time, VMARK Common Stock and cash may be issued and paid in accordance with this Article I to a transferee if the Certificate evidencing such Shares is presented to the Exchange Agent, accompanied by all documents required by law to evidence and effect such transfer pursuant to this Section 1.07(b) and by evidence that any applicable stock transfer taxes have been paid. Until so surrendered, each outstanding Certificate which, prior to the Effective Time, represented shares of UNIDATA Common Stock, shall be deemed from and after the Effective Time, for all corporate purposes other than the payment of dividends, to evidence the ownership of the number of full shares of VMARK Common Stock into which such shares of UNIDATA Common Stock may be exchanged in accordance herewith and the right to receive an amount in cash in lieu of the issuance of any fractional shares in accordance with Section 1.06(d). (c) Distributions With Respect to Unexchanged UNIDATA Common Stock. No dividends or other distributions with respect to VMARK Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the VMARK Common Stock such holder is entitled to receive until such holder shall surrender such Certificate. Subject to applicable law, following the surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of VMARK Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of VMARK Common Stock. (d) Transfers of Ownership. If any certificate evidencing shares of VMARK Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange shall have paid to VMARK, or any agent designated by VMARK, any transfer or other taxes required by I-4 13 reason of the issuance of a certificate for shares of VMARK Common Stock in any name other than that of the registered holder of the Certificate surrendered. (e) No Liability. VMARK and UNIDATA shall have no liability to any holder of UNIDATA Common Stock for any Merger Consideration (or dividends or distributions with respect thereto) which are delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (f) Withholding Rights. VMARK or the Exchange Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable to any holder of UNIDATA Common Stock such amounts as VMARK or the Exchange Agent may be required to deduct and withhold with respect to any provision of Federal, state, local or foreign tax laws. To the extent that amounts are so withheld by VMARK or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by VMARK or the Exchange Agent. (g) Escrowed Shares. As of the Effective Time, VMARK shall issue 50,000 shares of VMARK Common Stock (the "Escrowed Shares") and deliver a certificate or certificates therefor to Choate, Hall & Stewart (the "Escrow Agent") to be held and distributed in accordance with an agreement substantially in the form of Exhibit C (the "Escrow Agreement"). The Escrowed Shares shall be deemed to be part of the Merger Consideration and shall be allocated pro rata in accordance with the number of outstanding shares immediately prior to the Effective Time among the holders of UNIDATA Class A Common Stock and Class B Common Stock (treating shares of each class equally), other than holders of Dissenting Shares. In the event the Escrow Agent declines or is unable to serve prior to the Closing, it shall be succeeded by such person or entity, as VMARK and UNIDATA shall agree. Section 1.08. Stock Transfer Books. At the Effective Time, the stock transfer books of UNIDATA shall be closed, and there shall be no further registration of transfers of UNIDATA Common Stock on the records of UNIDATA. Section 1.09. Dissenting Shares. (a) Notwithstanding any provision of this Agreement to the contrary, any shares of UNIDATA Common Stock held by a holder who has exercised appraisal rights for such shares in accordance with the applicable provisions of the Colorado Law and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal rights (the "Dissenting Shares"), shall not be converted into, or represent a right to receive, the Merger Consideration pursuant to Section 1.06, but the holder thereof shall be entitled only to such rights as are granted by the Colorado Law with respect to the Dissenting Shares. (b) Notwithstanding the provisions of Section 1.09(a), if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect such rights or otherwise) such holder's appraisal rights, then, as of the later of Effective Time or the occurrence of such withdrawal or loss, such holder's shares shall automatically be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificate or Certificates in accordance with the terms hereof.

Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed (a "Lost Certificate"), the Exchange Agent shall, upon the making of an affidavit of that fact by the registered owner thereof, deliver to such owner such Merger Consideration as may be required pursuant to Section 1.06; provided, however, that VMARK may, in its sole discretion and as a condition precedent to the delivery thereof, require the registered owner of such Lost Certificate to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against VMARK or the Exchange Agent with respect to the Lost Certificate.

As promptly as practicable after the execution of this Agreement, VMARK shall prepare and file with the SEC (with appropriate requests for confidential treatment) a preliminary form of the Joint Proxy Statement/Prospectus and other proxy materials related thereto. Following clearance of the Joint Proxy Statement Prospectus by the SEC, VMARK shall prepare and file with the SEC a registration statement on Form S-4, containing the prospectus which is a part of the Joint Proxy Statement/Prospectus, in connection with the registration under the Securities Act of the shares of VMARK Common Stock to be issued in the Merger (the "Registration Statement").

Each of UNIDATA and VMARK shall use reasonable efforts to have or cause the Registration Statement to become effective (including clearing the Joint Proxy Statement/Prospectus with the SEC) as promptly as practicable, and shall take all actions required under any applicable federal or state securities laws in connection with the issuance of shares of VMARK Common Stock pursuant to the Merger. Without limiting the generality of the foregoing, each of UNIDATA and VMARK agrees to use all reasonable efforts, after consulting with the other party, to respond promptly to any comments made by the SEC with respect to the Joint Proxy Statement/Prospectus (including each preliminary version thereof) and the Registration Statement (including each amendment and I-31 40 supplement thereto). Each of UNIDATA and VMARK shall, and shall cause it respective representatives to, fully cooperate with the other party and its respective representatives in the preparation of the Joint Proxy Statement/Prospectus and the Registration Statement, and shall, upon request, furnish the other party with all information concerning it and its affiliates, directors, officers and stockholders as the other may reasonably request in connection with the preparation of the Joint Proxy Statement/Prospectus and the Registration Statement. The Joint Proxy Statement/Prospectus shall include the determination and recommendation of the Board of Directors of UNIDATA and VMARK that their respective stockholders vote in favor of the approval and adoption of this Agreement and the Merger; provided, however, that the Board of Directors of UNIDATA or VMARK may withdraw, modify or change such respective recommendation if either such Board of Directors determines in good faith, based upon the advice of outside counsel, that making such recommendation, or the failure to so withdraw, modify or change its recommendation, or the failure to recommend any other offer or proposal, could reasonably be deemed to cause the members of such Board of Directors to breach their fiduciary duties under applicable law. As promptly as practicable after the Registration Statement shall have become effective, UNIDATA and VMARK shall cause the Proxy Statement to be mailed to their respective stockholders. Thereafter, UNIDATA and VMARK shall each notify the other as promptly as practicable upon becoming aware of any event or circumstance which should be described in an amendment of, or a supplement to, the Joint Proxy Statement/Prospectus or the Registration Statement, and UNIDATA and VMARK shall each notify the other as promptly as practicable after the receipt by it of any written or oral comments of the SEC on, or of any written or oral request by the SEC for amendments or supplements to, the Proxy Statement or the Registration Statement, and shall promptly supply the other with copies of all correspondence between it or any of its representatives and the SEC with respect to any of the foregoing filings.

Upon reasonable notice and subject to restrictions contained in confidentiality agreements to which UNIDATA or VMARK may be subject (from which UNIDATA and VMARK shall each use reasonable efforts to be released), UNIDATA and VMARK shall each (and shall cause each of their subsidiaries to) afford to the officers, employees, accountants, counsel and other representatives of the other, reasonable access, during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records and, during such period, UNIDATA and VMARK shall each (and shall cause each of their subsidiaries to) furnish promptly to the other all information concerning its business, properties and personnel as such other party may reasonably request, and UNIDATA and VMARK shall each make available to the other the appropriate individuals (including attorneys, accountants and other professionals) for discussion of the other's business, properties and personnel as either VMARK or UNIDATA may reasonably request. Each party shall keep such information confidential in accordance with the terms of the Confidentiality and Standstill Agreements, dated February 19, 1997 and February 26, 1997 (the "Confidentiality Agreements"), each between VMARK and UNIDATA. Section 5.04. Consents, Approvals. UNIDATA and VMARK shall each use reasonable best efforts to obtain all consents, waivers, approvals, authorizations or orders (including, without limitation, all United States and foreign governmental and regulatory rulings and approvals), and UNIDATA and VMARK shall make all filings (including, without limitation, all filings with United States and foreign governmental or regulatory agencies) required in connection with the authorization, execution and delivery of this Agreement by UNIDATA and VMARK and the consummation by them of the transactions contemplated hereby.

Section 5.05. Stock Options. (a) At the Effective Time, the obligation to issue shares under each outstanding option to purchase UNIDATA Common Stock (each a "Stock Option") granted under UNIDATA's 1992 Stock Option Plan, 1993 Stock Option Plan, 1994 Stock Option Plan, 1995 Stock Option Plan, 1996 Stock Option Plan, and 1997 Stock Option Plan, each as amended (collectively, the "UNIDATA Stock Option Plans") and to former employees of O2 pursuant to the O2 Transaction, all of which shall be fully vested and exercisable at the Effective Time pursuant to the terms of the applicable Stock Option, shall be deemed assumed by VMARK and each such option shall be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such Stock Option prior to the Effective Time, the whole number (disregarding any fractional shares) of VMARK Common Stock as the holder of such Stock Option would have been entitled to receive pursuant to the Merger had such holder exercised such option in full immediately prior to the Effective Time (not taking into account whether or not such option was in fact exercisable), at a price per share equal to (x) the aggregate exercise price for UNIDATA Common Stock otherwise purchasable pursuant to such Stock Option, divided by (y) the number of shares of VMARK Common Stock deemed purchasable pursuant to such Stock Option, provided, however, that the exercisability or the other vesting of the assumed options and the underlying stock shall continue to be determined by reference to stock option agreements executed pursuant to UNIDATA's Stock Option Plans, and provided, further, that references in any Stock Option to UNIDATA, the board of directors of UNIDATA or any committee thereof, and any UNIDATA Stock Option Plan shall, commencing at the Effective Time, unless inconsistent with the context, be to VMARK, the board of directors of VMARK or a committee thereof, and VMARK's 1986 Stock Option Plan (for officers) or 1995 Non-Statutory Option Plan (for non-officers), respectively. (b) As soon as practicable after the Effective Time, VMARK shall deliver to each holder of an outstanding Stock Option an appropriate notice setting forth such holder's rights pursuant thereto and such Stock Option shall continue in effect on the same terms and conditions (including further anti-dilution provisions and subject to the adjustments required by this Section 5.05 after giving effect to the Merger). VMARK shall comply with the terms of all such Stock Options and ensure, to the extent required by, and subject to the provisions of, any such UNIDATA Stock Plan that Stock Options which qualified for special tax treatment prior to the Effective Time continue to so qualify after the Effective Time. VMARK shall take all corporate action necessary to reserve for issuance a sufficient number of VMARK Common Stock for delivery pursuant to the terms set forth in this Section 5.05. (c) VMARK shall use reasonable efforts after the Effective Time to maintain the effectiveness of a registration statement under the Securities Act with respect to the issuance by VMARK of shares of VMARK Common Stock which may be issued pursuant to the UNIDATA Options as provided for above in this Section 5.05. Section 5.06 Warrants. At the Effective Time, VMARK shall assume in writing all obligations under the UNIDATA Warrants (as defined below), and the holders of the UNIDATA Warrants thereafter shall have the right to acquire, on the same pricing and payment terms and conditions as are currently applicable under the UNIDATA Warrants, the same number of shares of VMARK Common Stock as the holders of the UNIDATA Warrants would have been entitled to receive in the Merger had such holder exercised the UNIDATA Warrants in full immediately prior to the Effective Time (rounded downward to the nearest whole number), at the price per share (rounded downward to the nearest whole cent) equal to (y) the aggregate exercise price for the shares of UNIDATA Common Stock purchasable pursuant to each UNIDATA Warrant immediately prior to the Effective Time divided by (z) the number of full shares of VMARK Common Stock deemed purchasable pursuant to such UNIDATA Warrant in accordance with the foregoing. As of the Effective Time, all of the UNIDATA warrants shall be fully vested and exercisable according to their terms. The "UNIDATA Warrants" mean, collectively, (i) the Warrant Agreements I-33 42 between UNIDATA and each of Massachusetts Mutual Life Insurance Company, Cudd & Co., and Webell & Co. for warrants to purchase an aggregate of 250,000 shares of UNIDATA Class B Common Stock and (ii) the Warrant Agreements between UNIDATA and each of Derek Miller and Neil Miller for warrants to purchase an aggregate of 255,000 shares of UNIDATA Class A Common Stock. Section 5.07. Notification of Certain Matters. UNIDATA shall give prompt notice to VMARK, and VMARK shall give prompt notice to UNIDATA, of (i) the occurrence or non-occurrence of any event which would cause any representation or warranty made by the respective parties in this Agreement to be materially untrue or inaccurate, and (ii) any failure of UNIDATA or VMARK, as the case may be, to materially comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 5.07 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice, and provided further, that failure to give such notice shall not be treated as a breach of covenant for the purposes of Sections 6.02(b) or 6.03(b) unless the failure to give such notice results in material prejudice to the other party. Section 5.08. Further Action/Tax Treatment. Upon the terms and subject to the conditions hereof, each of the parties hereto shall use reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all other things necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement, to obtain in a timely manner all necessary waivers, consents and approvals and to effect all necessary registrations and filings, and to otherwise satisfy or cause to be satisfied all conditions precedent to its obligations under this Agreement. The foregoing covenant shall not include any obligation by VMARK to agree to divest, abandon, license or take similar action with respect to any assets (tangible or intangible) of VMARK or UNIDATA. Both VMARK and UNIDATA shall each use reasonable efforts to cause the Merger to qualify, and will not (either before or after consummation of the Merger) take any actions which could prevent the Merger from qualifying, as a reorganization within the meaning of Section 368(a) of the Code. Section 5.09. Public Announcements. VMARK and UNIDATA shall consult with each other before issuing any press release or other public statement with respect to the Merger or this Agreement and shall not issue any such press release or make any such public statement without the prior consent of the other party, which shall not be unreasonably withheld; provided, however, that a party may, without the prior consent of the other party, issue such press release or make such public statement as may upon the advice of counsel be required by law if it has used reasonable efforts to consult first with the other party.

VMARK shall use reasonable efforts to cause the shares of VMARK Common Stock to be issued in the Merger to be approved for quotation on the Nasdaq National Market prior to the Effective Time.

Section 5.12. Pooling Accounting Treatment. UNIDATA and VMARK shall use reasonable efforts to avoid taking any action which would adversely affect the ability of both parties to treat the Merger as a pooling of interests and shall take such action as may be reasonably required to negate the impact of any past actions which would adversely impact the ability of VMARK or UNIDATA, as the case may be, to treat the Merger as a pooling of interests. Section 5.13. Indemnification; Directors' and Officers' Insurance. All rights to indemnification now existing in favor of the present or former directors or officers of UNIDATA or any of its subsidiaries as provided in UNIDATA's Articles of Incorporation and Bylaws, or in the certificate or articles of incorporation, by-laws or similar documents of any such subsidiaries, in effect as of the date hereof shall, with respect to matters occurring prior to the Effective Time, survive the Merger and continue in full force and effect after the Effective Time. All rights to indemnification in respect of any such claim or claims shall continue until I-34 43 disposition of such claim or claims. VMARK and UNIDATA further agree that all rights to indemnification now existing in favor of the present or former directors or officers of UNIDATA or any of its subsidiaries in any indemnification agreement between such person and UNIDATA or any such subsidiary, as the case may be, shall survive the Merger and continue in full force and effect in accordance with the terms of such agreement. Until the sixth anniversary of the Effective Time, VMARK shall maintain in effect with respect to matters occurring prior to the Effective Time, to the extent available, the policy of directors' and officers' liability insurance currently maintained by UNIDATA on behalf of its officers and directors and those of its subsidiaries; provided, however, that VMARK may substitute therefor a policy containing coverage, terms and conditions which are no less advantageous to the present or former directors and officers of UNIDATA. Notwithstanding anything to the contrary contained in this Agreement, the provisions of this Section 5.13 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each present and former director and officer of UNIDATA. Section 5.14. Employee Benefits (a) VMARK will maintain without change for a period of twelve months after the Effective Time each severance program and policy of UNIDATA listed in Schedule 2.13(d) (including any such plan, program or policy that is subject to the approval of the Board of Directors of UNIDATA as of the date of this Agreement) with respect to each VMARK employee who was employed by UNIDATA immediately prior to the Effective Time and for purposes of any such severance program or policy and any severance program and policy which UNIDATA was required to maintain by law; except as set forth in Section 5.14(d) below, VMARK will give full credit to such VMARK employee for all service performed for UNIDATA. VMARK will honor all severance and retention agreements in effect as of the Effective Time. (b) With respect to each VMARK Employee Plan, each VMARK employee employed by UNIDATA immediately prior to the Effective Time shall receive credit for all service performed for UNIDATA; such service credit shall apply for all purposes, including but not limited to, any vacation, sick time, insurance or other benefits and any eligibility or vesting requirements under any VMARK Employee Plan. (c) As of the Effective Time, each VMARK employee employed by UNIDATA immediately prior to the Effective Time shall be enrolled in the Group Health Benefit Plan for Employees of VMARK, or any successor plan thereto ("Group Health Plan") and shall be entitled to participate in the Group Health Plan without limitation or exclusion for any preexisting conditions applicable to any such employee or his enrolled dependents, except to the extent that any such preexisting condition limitation or exclusion applied to such individual under the group health plan provided by UNIDATA prior to the Effective Time. For purposes of participation in the Group Health Plan, each VMARK employee employed by UNIDATA immediately prior to the Effective Time shall also receive credit for all payments made toward deductible, co-payment and out-of-pocket limits under the group health plan of UNIDATA in which such employee was a participant immediately prior to the Effective Time for the plan year which includes the Effective Time as if such payments had been made for similar purposes for such period under the Group Health Plan by an employee employed by VMARK immediately prior to the Effective Time. (d) As soon as practicable after the Effective Time, VMARK will provide to each executive officer of UNIDATA that VMARK employs after the Merger (as listed on Schedule 5.14(d)) with a split-dollar insurance arrangement that provides substantially similar economic and other terms to those existing for current VMARK executives, provided, that for purposes of vesting of these agreements, each employee shall be considered a new employee of VMARK as of the Effective Time. Section 5.15. Name of the Surviving Corporation. Each of VMARK and UNIDATA shall use its best efforts to select a name for the Surviving Corporation prior to the last practicable date on which such name can be included in the Joint Proxy Statement/Prospectus to be mailed to the stockholders of VMARK. Provided such name has been selected in accordance with the foregoing, at the Effective Time, VMARK will I-35 44 change its name to a name mutually satisfactory to VMARK and UNIDATA, subject to approval of VMARK's stockholders.

Dresher registration rights with respect to his shares of VMARK Common Stock received at the Effective Time provided such rights are mutually satisfactory to Mr. Dresher and VMARK. Such rights shall be on standard, reasonable terms, including unlimited "piggyback" rights, subject to standard underwriter cutbacks, and two demand registrations on Form S-3, subject to reasonable blackout periods and other restrictions, and such other terms as the parties shall mutually agree. Section 5.18. Fairness Opinion; Restructuring. In the event that the Merger is not to be treated as a pooling of interests for accounting purposes, UNIDATA and VMARK shall each use its reasonable best efforts (a) to cause Volpe Brown Whelan & Co, LLC, or such other financial advisor reasonably satisfactory to VMARK, to deliver to VMARK an opinion that the consideration to be paid in the Merger is fair, from a financial point of view, to the stockholders of VMARK, and (b) to restructure the post-Merger operating plan for the Surviving Corporation developed by VMARK and UNIDATA to the extent commercially reasonable to permit the issuance of such opinion, provided that neither party shall have an obligation hereunder if the reason that the Merger is not to be treated as a pooling of interests for accounting purposes is due to a failure to observe the covenants in Section 5.12 by the other party or a Stockholder Support Agreement by the other party's affiliate signatory thereto, provided further that the breaching party shall still be obligated to perform the covenants contained in this section if the non-breaching party so requests.

WHEREAS, VMARK and UNIDATA propose to enter into an Agreement and Plan of Merger and Reorganization, of even date herewith (the "Merger Agreement"), which provides that, among other things, upon the terms and subject to the conditions thereof, UNIDATA will be merged with and into VMARK, with VMARK continuing as the surviving corporation; and WHEREAS, as a condition to the willingness of UNIDATA to enter into the Merger Agreement, UNIDATA has required that VMARK agree, and in order to induce UNIDATA to enter into the Merger Agreement VMARK has agreed, to grant UNIDATA an option to purchase certain shares of common stock of VMARK, in accordance with the terms of this Agreement; and WHEREAS, pursuant to the terms of an agreement of even date herewith, UNIDATA has granted VMARK an option to acquire certain shares of common stock of UNIDATA. NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto hereby agree as follows: ARTICLE I THE STOCK OPTION Section 1.1. Grant of Stock Option. VMARK hereby grants to UNIDATA an irrevocable option (the "Stock Option") to purchase up to 1,624,988 shares (the "Option Shares") of common stock, par value $.01 per share, of VMARK ("VMARK Common Stock"), including the associated rights (the "VMARK Rights") to purchase shares of VMARK capital stock pursuant to the Rights Agreement (the "Rights Plan"), dated as of June 12, 1996, between VMARK and State Street Bank and Trust Company, in the manner set forth below at a price (the "Purchase Price") of $9.87 per Option Share. All references in this Agreement to shares of VMARK Common Stock issued to UNIDATA hereunder shall be deemed to include the VMARK Rights associated therewith. Capitalized terms used herein but not defined herein shall have the meanings set forth in the Merger Agreement. Section 1.2. Exercise of Stock Option. (a) Subject to the satisfaction of the conditions set forth in Section 1.3 hereof, the Stock Option may be exercised by UNIDATA, in whole or in part, at any time or from time to time after the occurrence of an Exercise Event (as defined below) and prior to the Termination Date (as defined below). (b) An "Exercise Event" shall occur for purposes of this Agreement upon the occurrence of any event or circumstance which, pursuant to the terms of Section 7.03(c) of the Merger Agreement, would entitle UNIDATA, upon termination of the Merger Agreement, to payment of the termination fee specified in clauses (i), (ii) and (iii) Section 7.03(c) of the Merger Agreement (regardless of whether the Merger Agreement has actually been terminated as a result of such event or circumstance). Termination of the Merger Agreement pursuant to Section 7.03(c)(iv) of the Merger Agreement shall not be an Exercise Event. I-44 53 (c) The "Termination Date" shall occur for purposes of this Agreement upon the first to occur of any of the following: (i) the Effective Time; (ii) the date on which the Merger Agreement is terminated pursuant to Section 7.01 thereof, if an Exercise Event shall not have occurred on or prior to such termination date; or (iii) the date which is one year after the date on which the Merger Agreement is terminated pursuant to Section 7.01 thereof, if an Exercise Event shall have occurred on or prior to such termination date; provided that, with respect to clause (iii) above, if the Stock Option cannot be exercised as of such date by reason of any applicable judgment, decree, law, regulation or order, then the Termination Date shall be extended until thirty days after such impediment has been removed or such waiting period has expired. (d) In the event UNIDATA wishes to exercise the Stock Option, UNIDATA shall send a written notice (an "Exercise Notice") to VMARK specifying the total number of Option Shares UNIDATA wishes to purchase, the denominations of the certificate or certificates evidencing such Option Shares which UNIDATA wishes to receive, a date (a "Closing Date"), which shall be a business day which is at least five business days after delivery of such notice, and place for the closing of such purchase (a "Closing"). (e) Upon receipt of an Exercise Notice, VMARK shall be obligated to deliver to UNIDATA the number of Option Shares specified therein, in accordance with the terms of this Agreement, on the later of (i) the Closing Date and (ii) the first business day on which the conditions specified in Section 1.3 hereof shall be satisfied. Section 1.3. Conditions to Delivery of Option Shares. The obligation of VMARK to deliver Option Shares upon any exercise of the Stock Option is subject to the satisfaction of the following condition: (a) There shall be no preliminary or permanent injunction or other order by any court of competent jurisdiction preventing or prohibiting such exercise of the Stock Option or the delivery of the Option Shares in respect of such exercise. Section 1.4. Closings. At each Closing, VMARK will deliver to UNIDATA a certificate or certificates evidencing the number of Option Shares specified in UNIDATA's Exercise Notice, registered in the name of UNIDATA or its nominee, and UNIDATA will deliver to VMARK the aggregate Purchase Price for such Option shares. All payments made by UNIDATA to VMARK pursuant to this Section 1.4 shall be made, at the option of UNIDATA, (a) by wire transfer of immediately available funds, or (b) by delivery to VMARK of a certified or bank check or checks payable to or on the order of VMARK. Section 1.5. Adjustments Upon Share Issuances, Changes in Capitalization, etc. (a) In the event of any change in VMARK Common Stock or in the number of outstanding shares of VMARK Common Stock by reason of a stock dividend, stock split, reclassification, split-up, recapitalization, combination, exchange of shares or similar transaction or any other change in the corporate or capital structure of VMARK (including, without limitation, the declaration or payment of an extraordinary dividend of cash, securities or other property or a dividend under the Rights Plan), the type and number of shares or securities to be issued by VMARK upon exercise of the Stock Option, the Purchase Price and the VMARK Rights shall be adjusted appropriately, and proper provision shall be made in the agreements governing such transaction, so that UNIDATA shall receive upon exercise of the Stock Option the number and class of shares or other securities or property that UNIDATA would have received in respect of VMARK Common Stock if the Stock Option had been exercised immediately prior to such event, or the record date therefor, as applicable, and an election had been made to the fullest extent permitted to receive such securities, cash or other property. (b) In the event that VMARK shall enter into an agreement (i) to consolidate with or merge into any person, other than UNIDATA or one of its subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than UNIDATA or one of its subsidiaries, to merge into VMARK and VMARK shall be the continuing or surviving corporation, but, in I-45 54 connection with such merger, the then outstanding shares of VMARK Common Stock shall be changed into or exchanged for stock or other securities of VMARK or any other person or cash or any other property, or then outstanding shares of VMARK Common Stock shall after such merger represent less than 50% of the outstanding shares and share equivalents of the surviving corporation or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than UNIDATA or one of its subsidiaries, then, and in each such case, proper provision shall be made in the agreements governing such transaction so that UNIDATA shall receive upon exercise of the Stock Option the number and class of shares or other securities or property that UNIDATA would have received in respect of VMARK Common Stock if the Stock Option had been exercised immediately prior to such transaction, or the record date therefor, as applicable, and an election had been made to the fullest extent permitted to receive such securities, cash or other property. (c) No adjustment made in accordance with this Section 1.5 shall constitute or be deemed a waiver of any breach of any of VMARK's representations, warranties, covenants, agreements or obligations contained in the Merger Agreement. (d) The provisions of this Agreement, including, without limitation, Sections 1.1, 1.2, 1.4 and 3.2, shall apply with appropriate adjustments to any securities for which the Stock Option becomes exercisable pursuant to this Section 1.5. Section 1.6. Restrictive Legend. Each certificate representing Option Shares issued to UNIDATA hereunder shall include a legend in substantially the following form: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. ARTICLE II CASH EXERCISE Section 2.1. Cash Exercise. If at any time the Stock Option is then exercisable pursuant to the terms of Section 1.2 hereof, UNIDATA may elect, in lieu of exercising the Stock Option to purchase Option Shares provided in Section 1.1 hereof, to send a written notice to VMARK (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date VMARK shall pay to UNIDATA an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Option Shares subject to the Stock Option as UNIDATA shall specify. As used herein "Spread" shall mean the excess, if any, over the Purchase Price of the higher of (x) if applicable, the highest price per share of UNIDATA Common Stock (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by any person in an Alternative Transaction (as defined in clause (i), (ii) or (iii) of Section 7.03(e) of the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing sales price of the shares of VMARK Common Stock on the last trading day immediately prior to the date of the Cash Exercise Notice as quoted on The Nasdaq National Market (the "Closing Price"). If the Alternative Purchase Price includes any property other than cash, the Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Purchase Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing sales prices (or the average of the closing bid and asked prices if closing sales prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date of the Cash Exercise Notice shall be deemed to equal the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and, as of the payment date for the Spread, agreement on the value of such other property has not been reached, the Alternative Purchase Price shall be deemed to equal the Closing Price. Upon exercise of UNIDATA's right to receive cash pursuant to this Article II and the payment of such cash to UNIDATA, the obligations of VMARK to deliver Option Shares pursuant to Section I-46 55 1.2(e) shall be terminated with respect to such number of Option Shares for which UNIDATA shall have elected to be paid the Spread.

(a) VMARK shall, at its expense, use reasonable best efforts to cause the Option Shares to be approved for quotation on The Nasdaq National Market System (the "NASDAQ/NMS"), subject to notice of issuance, as promptly as practicable following the date of this Agreement, and will provide prompt notice to the NASDAQ/NMS of the issuance of each Option Share. (b) VMARK shall use its reasonable best efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated hereunder. Section 4.2. Registration. (a) As used in this Agreement, "Registrable Securities" means each of the Option Shares issued to UNIDATA hereunder and any other securities issued in exchange for, or issued as dividends or otherwise on or in respect of, any of such Option Shares. (b) At any time or from time to time within two years of the first Closing, UNIDATA may make a written request to VMARK for registration under and in accordance with the provisions of the Securities Act of 1993, as amended (the "Securities Act") with respect to all or part of the Registrable Securities (a "Demand Registration"). A Demand Registration may be, at the option of UNIDATA, a shelf registration or a registration involving an underwritten offering. As soon as reasonably practicable after UNIDATA's request I-47 56 for a Demand Registration, VMARK shall file one or more registration statements on any appropriate form with respect to all of the Registrable Securities requested to be so registered; provided that VMARK will not be required to file any such registration statement during any period of time (not to exceed 60 days after such request in the case of clause (A) below or 90 days in the case of clause (B) or (C) below) when (A) VMARK is in possession of material non-public information which it reasonably believes would be detrimental to be disclosed at such time and, in the written opinion of outside counsel to VMARK, such information would have to be disclosed if a registration statement were filed at that time, (B) VMARK is required under the Securities Act to include audited financial statements for any period in such registration statement that are not yet available for inclusion therein, or (C) VMARK determines, in its reasonable judgment, that such registration would interfere with any financing, acquisition or other material transaction involving VMARK or any of its affiliates. VMARK shall use its best efforts to have the Demand Registration declared effective as soon as reasonably practicable after such filing and to keep the Demand Registration continuously effective for a period of at least ninety days following the date on which the Demand Registration is declared effective, in the case of an underwritten offering, or at least six months following the date on which the Demand Registration is declared effective, in the case of a shelf registration; provided that, if for any reason the effectiveness of any Demand Registration is suspended, the required period of effectiveness shall be extended by the aggregate number of days of each such suspension; and provided, further, that the effectiveness of any Demand Registration may be terminated if and when all of the Registrable Securities covered thereby shall have been sold. UNIDATA shall be entitled to two Demand Registrations. If any Demand Registration involves an underwritten offering, (i) UNIDATA shall have the right to select the managing underwriter, which shall be reasonably acceptable to VMARK, (ii) VMARK shall enter into an underwriting agreement in customary form and (iii) unless the managing underwriter reasonably determines that such restriction would materially and adversely affect the success of such offering, the underwriter shall use its best efforts to prevent any person and its affiliates from purchasing through such offering Registrable Securities representing more than two percent of the outstanding shares of VMARK Common Stock on a fully diluted basis. VMARK shall not include in any Demand Registration any securities other than the Registrable Securities requested to be registered therein by UNIDATA. (c) If at any time within three years of the first Closing, VMARK proposes to file a registration statement under the Securities Act with respect to any shares of any class of its equity securities to be sold for the account of VMARK (other than a registration statement on Form S-4 or Form S-8 or any successor form), and the registration form to be used may be used for the registration of Registrable Securities, then VMARK shall in each case give written notice of such proposed filing to UNIDATA at least twenty days before the anticipated filing date, and UNIDATA shall have the right to include in such registration such number of Registrable Securities as UNIDATA may request (such request to be made by written notice to VMARK within fifteen days following UNIDATA's receipt from VMARK of such notice of proposed filing). VMARK shall use its best efforts to cause the managing underwriter of any proposed underwritten offering to permit UNIDATA to include in such offering all Registrable Securities requested by UNIDATA to be included in the registration for such offering on the same terms and conditions as any similar securities of VMARK included therein. Notwithstanding the foregoing, if the managing underwriter of such offering advises UNIDATA that, in the reasonable opinion of such underwriter, the amount of Registrable Securities which UNIDATA requests to be included in such offering would materially and adversely affect the success of such offering, then the amount of Registrable Securities to be offered shall be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by such underwriter, provided, however, that if the amount of Registrable Securities shall be so reduced, VMARK shall not be permitted to include in such registration any securities other than securities to be issued by VMARK and Registrable Securities. (d) In the event that Registrable Securities are included in a registration statement pursuant to Section 4.2(c) hereof, UNIDATA agrees not to effect any public sale or distribution of the issue being registered or a similar security of VMARK, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the ten business days prior to, and during the 90-day period beginning on, the effective date of such registration statement (except as part of such registration), if and to the extent timely notified in writing by VMARK, in the case of a non- I-48 57 underwritten public offering, or by the managing underwriter, in the case of an underwritten public offering. In the event that UNIDATA requests a Demand Registration or if Registrable Securities are included in a registration pursuant to Section 4.2(c) hereof, VMARK agrees not to effect any public sale or distribution of the issue being registered or a similar security of VMARK, or any securities convertible into or exchangeable for such securities, during the period from such request until 90 days after the effective date of such registration statement (except as part of such registration or pursuant to a registration of securities on Form S-4 or Form S-8 or any successor form). (e) Notwithstanding anything to the contrary contained herein, in the event that UNIDATA requests a Demand Registration or a registration of Registrable Securities pursuant to Section 4.2(b) or 4.2(c) hereof, respectively, VMARK shall have the right to purchase all, but not less than all, of the Registrable Securities requested to be so registered, upon the terms and subject to conditions set forth in this Section 4.2(e). If VMARK wishes to exercise such purchase right, then within two business days following receipt of UNIDATA's request for such registration, VMARK shall send a written notice (a "Repurchase Notice") to UNIDATA specifying that VMARK wishes to exercise such purchase right, a date for the closing of such purchase, which shall not be more than thirty days after delivery of such Repurchase Notice, and a place for the closing of such purchase (a "Repurchase Closing"). Upon delivery of a Repurchase Notice, a binding agreement shall be deemed to exist between UNIDATA and VMARK providing for the purchase by VMARK of the Registrable Securities requested to be registered by UNIDATA, upon the terms and subject to the conditions set forth in this Section 4.2(e). The purchase price per share or other unit of Registrable Securities (the "Repurchase Price") shall equal the average per share or per unit closing price as quoted on the NASDAQ/NMS (or if not then quoted thereon, on such other exchange or quotation system on which the Registrable Securities are quoted) for the period of five trading days ending on the trading day immediately prior to the date on which UNIDATA requests a registration of the Registrable Securities which VMARK subsequently elects to purchase. UNIDATA's obligation to deliver any Registrable Securities at a Repurchasing Closing shall be subject to the conditions that, at such Repurchase Closing. VMARK shall have delivered to UNIDATA a certificate signed on behalf of VMARK by VMARK's chief executive officer and chief financial officer, which certificate shall be reasonably satisfactory in form and substance to UNIDATA, to the effect that the purchase by VMARK of such Registrable Securities (i) is permitted under applicable Delaware corporate law and under the fraudulent conveyance provisions of the federal bankruptcy code and (ii) does not violate any material agreement to which VMARK or any of its subsidiaries is a party or by which any of their properties or assets is bound. At any Repurchase Closing, VMARK shall pay to UNIDATA the aggregate Repurchase Price for the Registrable Securities being purchased by wire transfer of immediately available funds or by delivering to UNIDATA a certified or bank check payable to or on the order of UNIDATA in an amount equal to such aggregate Repurchase Price, and UNIDATA will surrender to VMARK a certificate or certificates evidencing such Registrable Securities. No purchase of Registrable Securities by VMARK pursuant to this Section 4.2(e) shall reduce or otherwise modify VMARK's registration obligations under this Section 4.2 (including, without limitation, the number of Demand Registrations which VMARK is obligated to effect) with respect to any Registrable Securities held by UNIDATA following such purchase. (f) The registrations effected under this Section 4.2 shall be effected at VMARK's expense except for underwriting commissions allocable to the Registrable Securities and the fees and disbursements of UNIDATA's counsel. VMARK shall indemnify and hold harmless UNIDATA, its affiliates and controlling persons and their respective officers, directors, agents and representatives from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, all out-of-pocket expenses, investigation expenses, expenses incurred with respect to any judgment and fees and disbursements of counsel and accountants) arising out of or based upon any statements contained in, or omissions or alleged omissions from, each registration statement (and related prospectus) filed pursuant to this Section 4.2; provided, however, that VMARK shall not be liable in any such case to UNIDATA or any affiliate or controlling person of UNIDATA or any of their respective officers, directors, agents or representatives to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or omission or alleged omission made in such registration statement or prospectus in reliance upon, I-49 58 and in conformity with, written information furnished to VMARK specifically for use in the preparation thereof by UNIDATA, such affiliate, controlling person, officer, director, agent or representative, as the case may be. ARTICLE V COVENANTS OF UNIDATA UNIDATA hereby covenant and agrees as follows: Section 5.1. Distribution. UNIDATA shall acquire the Option Shares for investment purposes only and not with a view to any distribution thereof in violation of the Securities Act and shall not sell any Option Shares purchased pursuant to this Agreement except in compliance with the Securities Act.

If any term or other provision of this Agreement is held by a court or other competent authority to be invalid, illegal or incapable of being enforced by any rule of law, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law to the end that the transaction contemplated hereby are fulfilled to the extent possible.

By: ------------------------------------ Charles F. Kane Executive Vice President, Finance, Chief Financial Officer and Treasurer UNIDATA, INC. By: ------------------------------------ David W. Brunel President and Chief Operating Officer I-51 60 EXHIBIT B STOCK OPTION AGREEMENT (GRANTED TO VMARK) STOCK OPTION AGREEMENT, dated as of October 7, 1997 (this "Agreement"), between VMARK Software, Inc., a Delaware corporation ("VMARK"), and Unidata, Inc., a Colorado corporation ("UNIDATA"). WHEREAS, VMARK and UNIDATA propose to enter into an Agreement and Plan of Merger and Reorganization, of even date herewith (the "Merger Agreement"), which provides that, among other things, upon the terms and subject to the conditions thereof, UNIDATA will be merged with and into VMARK, with VMARK continuing as the surviving corporation; and WHEREAS, as a condition to the willingness of VMARK to enter into the Merger Agreement, VMARK has required that UNIDATA agree, and in order to induce VMARK to enter into the Merger Agreement UNIDATA has agreed, to grant VMARK an option to purchase certain shares of common stock of UNIDATA, in accordance with the terms of this Agreement; and WHEREAS, pursuant to the terms of an agreement of even date herewith, VMARK has granted UNIDATA an option to acquire certain shares of common stock of VMARK. NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto hereby agree as follows: ARTICLE I THE STOCK OPTION Section 1.1.

Capitalized terms used herein but not defined herein shall have the meanings set forth in the Merger Agreement. Section 1.2. Exercise of Stock Option. (a) Subject to the satisfaction of the conditions set forth in Section 1.3 hereof, the Stock Option may be exercised by VMARK, in whole or in part, at any time or from time to time after the occurrence of an Exercise Event (as defined below) and prior to the Termination Date (as defined below). (b) An "Exercise Event" shall occur for purposes of this Agreement upon the occurrence of any event or circumstance which, pursuant to the terms of Section 7.03(b) of the Merger Agreement, would entitle VMARK, upon termination of the Merger Agreement, to payment of the termination fee specified in Section 7.03(b) of the Merger Agreement (regardless of whether the Merger Agreement has actually been terminated as a result of such event or circumstance). (c) The "Termination Date" shall occur for purposes of this Agreement upon the first to occur of any of the following: (i) the Effective Time; (ii) the date on which the Merger Agreement is terminated pursuant to Section 7.01 thereof, if an Exercise Event shall not have occurred on or prior to such termination date; or (iii) the date which is one year after the date on which the Merger Agreement is terminated pursuant to Section 7.01 thereof, if an Exercise Event shall have occurred on or prior to such termination date; I-52 61 provided that, with respect to clause (iii) above, if the Stock Option cannot be exercised as of such date by reason of any applicable judgment, decree, law, regulation or order, then the Termination Date shall be extended until thirty days after such impediment has been removed or such waiting period has expired. (d) In the event VMARK wishes to exercise the Stock Option, VMARK shall send a written notice (an "Exercise Notice") to UNIDATA specifying the total number of Option Shares VMARK wishes to purchase, the denominations of the certificate or certificates evidencing such Option Shares which VMARK wishes to receive, a date (a "Closing Date"), which shall be a business day which is at least five business days after delivery of such notice, and place for the closing of such purchase (a "Closing"). (e) Upon receipt of an Exercise Notice, UNIDATA shall be obligated to deliver to VMARK the number of Option Shares specified therein, in accordance with the terms of this Agreement, on the later of (i) the Closing Date and (ii) the first business day on which the conditions specified in Section 1.3 hereof shall be satisfied. Section 1.3. Conditions to Delivery of Option Shares. The obligation of UNIDATA to deliver Option Shares upon any exercise of the Stock Option is subject to the satisfaction of the following condition: (a) There shall be no preliminary or permanent injunction or other order by any court of competent jurisdiction preventing or prohibiting such exercise of the Stock Option or the delivery of the Option Shares in respect of such exercise. Section 1.4. Closings. At each Closing, UNIDATA will deliver to VMARK a certificate or certificates evidencing the number of Option Shares specified in VMARK's Exercise Notice, registered in the name of VMARK or its nominee, and VMARK will deliver to UNIDATA the aggregate Purchase Price for such Option shares. All payments made by VMARK to UNIDATA pursuant to this Section 1.4 shall be made, at the option of VMARK, (a) by wire transfer of immediately available funds, or (b) by delivery to UNIDATA of a certified or bank check or checks payable to or on the order of UNIDATA. Section 1.5. Adjustments Upon Share Issuances, Changes in Capitalization, etc. (a) In the event of any change in UNIDATA Common Stock or in the number of outstanding shares of UNIDATA Common Stock by reason of a stock dividend, stock split, reclassification, split-up, recapitalization, combination, exchange of shares or similar transaction or any other change in the corporate or capital structure of UNIDATA (including, without limitation, the declaration or payment of an extraordinary dividend of cash, securities or other property), the type and number of shares or securities to be issued by UNIDATA upon exercise of the Stock Option and the Purchase Price shall be adjusted appropriately, and proper provision shall be made in the agreements governing such transaction, so that VMARK shall receive upon exercise of the Stock Option the number and class of shares or other securities or property that VMARK would have received in respect of UNIDATA Common Stock if the Stock Option had been exercised immediately prior to such event, or the record date therefor, as applicable, and an election had been made to the fullest extent permitted to receive such securities, cash or other property. (b) In the event that UNIDATA shall enter into an agreement (i) to consolidate with or merge into any person, other than VMARK or one of its subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than VMARK or one of its subsidiaries, to merge into UNIDATA and UNIDATA shall be the continuing or surviving corporation, but, in connection with such merger, the then outstanding shares of UNIDATA Common Stock shall be changed into or exchanged for stock or other securities of UNIDATA or any other person or cash or any other property, or then outstanding shares of UNIDATA Common Stock shall after such merger represent less than 50% of the outstanding shares and share equivalents of the surviving corporation or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than VMARK or one of its subsidiaries, then, and in each such case, proper provision shall be made in the agreements governing such transaction so that VMARK shall receive upon exercise of the Stock Option the number and class of shares or other securities or property that VMARK would have received in respect of UNIDATA Common Stock if the Stock Option had been exercised immediately prior to such transaction, or the record date therefor, as applicable, and an election had been made to the fullest extent permitted to receive such securities, cash or other property. I-53 62 (c) No adjustment made in accordance with this Section 1.5 shall constitute or be deemed a waiver of any breach of any of UNIDATA's representations, warranties, covenants, agreements or obligations contained in the Merger Agreement. (d) The provisions of this Agreement, including, without limitation, Sections 1.1, 1.2, 1.4 and 3.2, shall apply with appropriate adjustments to any securities for which the Stock Option becomes exercisable pursuant to this Section 1.5. Section 1.6. Restrictive Legend. Each certificate representing Option Shares issued to VMARK hereunder shall include a legend in substantially the following form: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. ARTICLE II CASH EXERCISE Section 2.1. Cash Exercise. If at any time the Stock Option is then exercisable pursuant to the terms of Section 1.2 hereof, VMARK may elect, in lieu of exercising the Stock Option to purchase Option Shares provided in Section 1.1 hereof, to send a written notice to UNIDATA (the "Cash Exercise Notice") specifying a date not later than 20 business days (except as set forth in clause (b)(ii) below) and not earlier than 10 business days following the date such notice is given on which date UNIDATA shall pay to VMARK an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Option Shares subject to the Stock Option as VMARK shall specify. As used herein "Spread" shall mean the excess, if any, over the Purchase Price of, (a) if UNIDATA Common Stock is publicly traded on a national securities exchange or The Nasdaq National Market (the "Exchange"), the higher of (i) if applicable, the highest price per share of UNIDATA Common Stock (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by any person in an Alternative Transaction (as defined in clause (i), (ii) or (iii) of Section 7.03(e) of the Merger Agreement) (the "Alternative Purchase Price") or (ii) the closing sales price of the shares of UNIDATA Common Stock on the last trading day immediately prior to the date of the Cash Exercise Notice as quoted on the Exchange (the "Closing Price"), or (b) if UNIDATA Common Stock is not publicly traded on an Exchange, the higher of (i) if applicable, the Alternative Purchase Price or (ii) the Fair Market Value (as defined below) of a share of UNIDATA Common Stock; provided that in such case the Cash Exercise Notice shall specify a date not later than 20 days beyond the determination of Fair Market Value. If the Alternative Purchase Price includes any property other than cash, the Alternative Purchase Price shall be the sum of (A) the fixed cash amount, if any, included in the Alternative Purchase Price plus (B) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing sales prices (or the average of the closing bid and asked prices if closing sales prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date of the Cash Exercise Notice shall be deemed to equal the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and, as of the payment date for the Spread, agreement on the value of such other property has not been reached, the Alternative Purchase Price shall be deemed to equal the Closing Price. For purposes of this Agreement, the "Fair Market Value" of a share of UNIDATA Common Stock shall be determined by dividing the appraised value of UNIDATA, as determined by an investment banker selected by and mutually satisfactory to UNIDATA and VMARK (or, in the case the parties cannot agree, by a majority of a panel of three investment bankers, one of which will be selected by UNIDATA, one of which will be selected by VMARK, and one of which will be selected by the two previously designated investment bankers), without discount for minority or illiquidity, by (II) the number of issued and outstanding shares of UNIDATA Common Stock on the date of the Cash Exercise Notice. Upon exercise of VMARK's right to receive cash pursuant to this Article II and the payment of such cash to VMARK, the obligations of I-54 63 UNIDATA to deliver Option Shares pursuant to Section 1.2(e) shall be terminated with respect to such number of Option Shares for which VMARK shall have elected to be paid the Spread. ARTICLE III REPRESENTATIONS AND WARRANTIES OF UNIDATA Section 3.1. Representations and Warranties of UNIDATA. UNIDATA represents and warrants to VMARK that (a) UNIDATA is a corporation duly organized, validly existing and in good standing under the laws of the State of Colorado and has all requisite corporate power and authority to enter into this Agreement and to consummate the transactions contemplated by this Agreement, (b) the execution and delivery by UNIDATA of this Agreement and the consummation by UNIDATA of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate action on the part of UNIDATA, (c) this Agreement has been duly executed and delivered by UNIDATA and constitutes the valid and binding obligation of UNIDATA, enforceable against UNIDATA in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles, (d) UNIDATA has taken all necessary corporate action to authorize and reserve and permit it to issue, and at all times from the date hereof through the Termination Date shall have reserved, all the Option Shares issuable pursuant to this Agreement, and UNIDATA will take all necessary corporate action to authorize and reserve and permit it to issue all additional shares of UNIDATA Common Stock or other securities which may be issued pursuant to Section 1.5 hereof, all of which, upon their issuance and delivery in accordance with the term of this Agreement, shall be duly authorized, validly issued, fully paid and nonassessable, shall be delivered free and clear of all security interests, liens, claims, pledges, options, rights of first refusal, agreements, limitation on VMARK's voting rights, charges and other encumbrances of any nature whatsoever (other than this Agreement) and shall not be subject to any preemptive rights, and (e) the execution and delivery of this Agreement by UNIDATA does not, and the consummation by UNIDATA of the transactions contemplated by this Agreement will not, conflict with, or result in a violation of, or default under (with or without notice or lapse of time or both), or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under (i) any provision of the Articles of Incorporation or Bylaws of UNIDATA or (ii) any mortgage, indenture, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to UNIDATA or its properties or assets. ARTICLE IV COVENANTS OF UNIDATA UNIDATA hereby covenant and agrees as follows: Section 4.1. Required Actions. UNIDATA shall use its reasonable best efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated hereunder. Section 4.2. Registration. (a) As used in this Agreement, "Registrable Securities" means each of the Option Shares issued to VMARK hereunder and any other securities issued in exchange for, or issued as dividends or otherwise on or in respect of, any of such Option Shares. (b) At any time or from time to time within two years of the first Closing, VMARK may make a written request to UNIDATA for registration under and in accordance with the provisions of the Securities Act of 1993, as amended (the "Securities Act") with respect to all or part of the Registrable Securities (a "Demand Registration"). A Demand Registration may be, at the option of VMARK, a shelf registration or a registration involving an underwritten offering. As soon as reasonably practicable after VMARK's request for a Demand Registration, UNIDATA shall file one or more registration statements on any appropriate form with respect to all of the Registrable Securities requested to be so registered; provided that UNIDATA will not be required to file any such registration statement during any period of time (not to exceed 60 days after such request in the I-55 64 case of clause (A) below or 90 days in the case of clause (B) or (C) below) when (A) UNIDATA is in possession of material non-public information which it reasonably believes would be detrimental to be disclosed at such time and, in the written opinion of outside counsel to UNIDATA, such information would have to be disclosed if a registration statement were filed at that time, (B) UNIDATA is required under the Securities Act to include audited financial statements for any period in such registration statement that are not yet available for inclusion therein, or (C) UNIDATA determines, in its reasonable judgment, that such registration would interfere with any financing, acquisition or other material transaction involving UNIDATA or any of its affiliates. UNIDATA shall use its best efforts to have the Demand Registration declared effective as soon as reasonably practicable after such filing and to keep the Demand Registration continuously effective for a period of at least ninety days following the date on which the Demand Registration is declared effective, in the case of an underwritten offering, or at least six months following the date on which the Demand Registration is declared effective, in the case of a shelf registration; provided that, if for any reason the effectiveness of any Demand Registration is suspended, the required period of effectiveness shall be extended by the aggregate number of days of each such suspension; and provided, further, that the effectiveness of any Demand Registration may be terminated if and when all of the Registrable Securities covered thereby shall have been sold. VMARK shall be entitled to two Demand Registrations. If any Demand Registration involves an underwritten offering, (i) VMARK shall have the right to select the managing underwriter, which shall be reasonably acceptable to UNIDATA, (ii) UNIDATA shall enter into an underwriting agreement in customary form and (iii) unless the managing underwriter reasonably determines that such restriction would materially and adversely affect the success of such offering, the underwriter shall use its best efforts to prevent any person and its affiliates from purchasing through such offering Registrable Securities representing more than two percent of the outstanding shares of UNIDATA Common Stock on a fully diluted basis. UNIDATA shall not include in any Demand Registration any securities other than the Registrable Securities requested to be registered therein by VMARK. (c) If at any time within three years of the first Closing, UNIDATA proposes to file a registration statement under the Securities Act with respect to any shares of any class of its equity securities to be sold for the account of UNIDATA (other than a registration statement on Form S-4 or Form S-8 or any successor form), and the registration form to be used may be used for the registration of Registrable Securities, then UNIDATA shall in each case give written notice of such proposed filing to VMARK at least twenty days before the anticipated filing date, and VMARK shall have the right to include in such registration such number of Registrable Securities as VMARK may request (such request to be made by written notice to UNIDATA within fifteen days following VMARK's receipt from UNIDATA of such notice of proposed filing). UNIDATA shall use its best efforts to cause the managing underwriter of any proposed underwritten offering to permit VMARK to include in such offering all Registrable Securities requested by VMARK to be included in the registration for such offering on the same terms and conditions as any similar securities of UNIDATA included therein. Notwithstanding the foregoing, if the managing underwriter of such offering advises VMARK that, in the reasonable opinion of such underwriter, the amount of Registrable Securities which VMARK requests to be included in such offering would materially and adversely affect the success of such offering, then the amount of Registrable Securities to be offered shall be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by such underwriter, provided, however, that if the amount of Registrable Securities shall be so reduced, UNIDATA shall not be permitted to include in such registration any securities other than securities to be issued by UNIDATA and Registrable Securities. (d) In the event that Registrable Securities are included in a registration statement pursuant to Section 4.2(c) hereof, VMARK agrees not to effect any public sale or distribution of the issue being registered or a similar security of UNIDATA, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the ten business days prior to, and during the 90-day period beginning on, the effective date of such registration statement (except as part of such registration), if and to the extent timely notified in writing by UNIDATA, in the case of a non-underwritten public offering, or by the managing underwriter, in the case of an underwritten public offering. In the event that VMARK requests a Demand Registration or if Registrable Securities are included in a registration pursuant to Section 4.2(c) hereof, UNIDATA agrees not to effect any public sale or distribution I-56 65 of the issue being registered or a similar security of UNIDATA, or any securities convertible into or exchangeable for such securities, during the period from such request until 90 days after the effective date of such registration statement (except as part of such registration or pursuant to a registration of securities on Form S-4 or Form S-8 or any successor form). (e) Notwithstanding anything to the contrary contained herein, in the event that VMARK requests a Demand Registration or a registration of Registrable Securities pursuant to Section 4.2(b) or 4.2(c) hereof, respectively, UNIDATA shall have the right to purchase all, but not less than all, of the Registrable Securities requested to be so registered, upon the terms and subject to conditions set forth in this Section 4.2(e). If UNIDATA wishes to exercise such purchase right, then within two business days following receipt of VMARK's request for such registration, UNIDATA shall send a written notice (a "Repurchase Notice") to VMARK specifying that UNIDATA wishes to exercise such purchase right, a date for the closing of such purchase, which shall not be more than thirty days after delivery of such Repurchase Notice, and a place for the closing of such purchase (a "Repurchase Closing"). Upon delivery of a Repurchase Notice, a binding agreement shall be deemed to exist between VMARK and UNIDATA providing for the purchase by UNIDATA of the Registrable Securities requested to be registered by VMARK, upon the terms and subject to the conditions set forth in this Section 4.2(e). The purchase price per share or other unit of Registrable Securities (the "Repurchase Price") shall equal the average per share or per unit closing price as quoted on the Exchange (or if not then quoted thereon, on such other exchange or quotation system on which the Registrable Securities are quoted) for the period of five trading days ending on the trading day immediately prior to the date on which VMARK requests a registration of the Registrable Securities which UNIDATA subsequently elects to purchase. VMARK's obligation to deliver any Registrable Securities at a Repurchasing Closing shall be subject to the conditions that, at such Repurchase Closing, UNIDATA shall have delivered to VMARK a certificate signed on behalf of UNIDATA by UNIDATA's chief executive officer and chief financial officer, which certificate shall be reasonably satisfactory in form and substance to VMARK, to the effect that the purchase by UNIDATA of such Registrable Securities (i) is permitted under applicable Colorado corporate law and under the fraudulent conveyance provisions of the federal bankruptcy code and (ii) does not violate any material agreement to which UNIDATA or any of its subsidiaries is a party or by which any of their properties or assets is bound. At any Repurchase Closing, UNIDATA shall pay to VMARK the aggregate Repurchase Price for the Registrable Securities being purchased by wire transfer of immediately available funds or by delivering to VMARK a certified or bank check payable to or on the order of VMARK in an amount equal to such aggregate Repurchase Price, and VMARK will surrender to UNIDATA a certificate or certificates evidencing such Registrable Securities. No purchase of Registrable Securities by UNIDATA pursuant to this Section 4.2(e) shall reduce or otherwise modify UNIDATA's registration obligations under this Section 4.2 (including, without limitation, the number of Demand Registrations which UNIDATA is obligated to effect) with respect to any Registrable Securities held by VMARK following such purchase. (f) The registrations effected under this Section 4.2 shall be effected at UNIDATA's expense except for underwriting commissions allocable to the Registrable Securities and the fees and disbursements of VMARK's counsel. UNIDATA shall indemnify and hold harmless VMARK, its affiliates and controlling persons and their respective officers, directors, agents and representatives from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, all out-of-pocket expenses, investigation expenses, expenses incurred with respect to any judgment and fees and disbursements of counsel and accountants) arising out of or based upon any statements contained in, or omissions or alleged omissions from, each registration statement (and related prospectus) filed pursuant to this Section 4.2; provided, however, that UNIDATA shall not be liable in any such case to VMARK or any affiliate or controlling person of VMARK or any of their respective officers, directors, agents or representatives to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or omission or alleged omission made in such registration statement or prospectus in reliance upon, and in conformity with, written information furnished to UNIDATA specifically for use in the preparation thereof by VMARK, such affiliate, controlling person, officer, director, agent or representative, as the case may be.

By: ----------------------------------- David W. Brunel President VMARK SOFTWARE, INC. By: ----------------------------------- Charles F. Kane Executive Vice President, Finance, Chief Financial Officer and Treasurer I-59 68 EXHIBIT C ESCROW AGREEMENT AGREEMENT made this day of December, 1997 by and among VMARK SOFTWARE, INC., a Delaware corporation ("VMARK"), James T. Dresher and David W. Brunel (together, the "Representatives") and CHOATE, HALL & STEWART (the "Escrow Agent"). WHEREAS, VMARK is the surviving corporation of a merger effective this date pursuant to an Agreement and Plan of Merger and Reorganization dated October 7, 1997 (the "Merger Agreement") between VMARK and Unidata, Inc., a Colorado corporation ("UNIDATA"); and WHEREAS, the Merger Agreement requires that a portion of the Merger Consideration be paid to the Escrow Agent to be held and distributed in accordance with an agreement substantially in the form hereof; NOW, THEREFORE, the parties hereby agree as follows: 1. Definitions. This Agreement is the Escrow Agreement to which reference is made in the Merger Agreement. Capitalized terms used in this Agreement and not defined herein shall have the same meaning as in the Merger Agreement. 2. Transfer of Escrowed Shares. Pursuant to Section 1.07(h) of the Merger Agreement, a certificate or certificates representing 50,000 shares of VMARK Common Stock registered in the name of the Escrow Agent (the "Escrowed Shares") has been delivered to the Escrow Agent, and the Escrow Agent acknowledges receipt of said certificate or certificates. 3. Investment Pending Distribution. The Escrowed Shares shall be held by the Escrow Agent subject to the direction of the Representatives to sell all or any portion thereof, provided that no sale thereof shall be made in violation of applicable securities laws. In the event of any sale thereof, the resulting funds shall be invested in short-term government securities or a mutual fund invested substantially solely in such securities, as directed by the Representatives. Interest and dividends shall not be added to or become part of the escrow account and shall be promptly distributed from time to time to the Stockholders (as defined in Section 5). 4. Distribution from Escrow Account. The Escrowed Shares and any other assets in the escrow account shall be distributed out of escrow by the Escrow Agent only as follows: (a) In the event that VMARK shall incur any loss, damage or expense, as a result of or in connection with any agreement between UNIDATA and Advent International Corporation ("Advent"), it shall be entitled to be indemnified and held harmless by the distribution, out of assets in the escrow account, of amounts equal to such loss, damages or expense, provided that (i) it shall not be entitled to indemnification hereunder in respect of the reimbursement to Advent of certain expenses not in excess of $100,000 or for costs and expenses, including legal fees, incurred in defending any claim by Advent, and (ii) it shall, jointly with the Representatives if they wish to participate therein (provided that in any event VMARK shall bear all costs and expenses, including legal fees), defend any claim by Advent (other than for the reimbursement of expenses up to $100,000 referred to above) vigorously and shall not settle any such claim without the consent of the Representatives. (b) When any loss, damage or expense, as to which VMARK is entitled to be indemnified and held harmless pursuant to (a) above, becomes reasonably quantifiable, VMARK shall promptly notify the Representatives and the Escrow Agent of the amount of the distribution it seeks out of the assets in the escrow account, which notice shall include reasonable detail in support of such amount. If the Representatives do not disagree with VMARK's entitlement to such amount by notice to the Escrow Agent within 21 days after receipt of such notice given by VMARK, the Escrow Agent shall distribute to VMARK out of the escrow account assets equal to the amount requested. If the Representatives do disagree with such entitlement by such notice, and such disagreement is not promptly resolved by discussion between VMARK and the Representatives, the matter shall be submitted to arbitration as provided in Section 8. I-60 69 (c) Upon the resolution (including pursuant to any applicable statute of limitations) of all claims by Advent described in (a) above, all assets remaining in the escrow account not subject to payment to VMARK shall be promptly distributed to the Stockholders. VMARK shall, and the Representatives may, notify the Escrow Agent and the other when it or they believe all such claims have been resolved, which notice shall include reasonable supporting detail. If the other party does not disagree with the notice by notice to the Escrow Agent within 21 days after receipt of the initial notice, then the Escrow Agent shall make the distribution to the Stockholders as provided above. If the other party does disagree by such notice, and such disagreement is not promptly resolved by discussion between VMARK and the Representatives, the matter shall be submitted to arbitration as provided in Section 8. 5. Allocation of Taxable Income. For purposes of taxation of any interest and dividends earned on assets held in escrow hereunder, the escrowed assets shall be deemed to have been placed in escrow by the holders of UNIDATA Class A Common Stock and Class B Common Stock (other than holders of Dissenting Shares) outstanding immediately prior to the Effective Time (the "Stockholders"), and any interest and dividends thereon shall be allocated to the Stockholders as provided in Section 6. 6. Distributions of Stockholders. All distributions to be made to the Stockholders hereunder shall be made to them pro rata in accordance with their respective holdings of UNIDATA Class A Common Stock of Class B Common Stock outstanding immediately prior to the Effective Time (treating such shares equally). 7. Matters relating to the Escrow Agents. (a) The Escrow Agent shall be entitled to rely and shall be protected in acting in reliance on any writing furnished to it by VMARK and the Representatives. The Escrow Agent shall not be liable to any party hereto by reason of any error of judgment, or any act taken or omitted in good faith, or for any matter in connection herewith unless caused by or arising out of its own gross negligence or bad faith. (b) The reasonable fees and expenses of the Escrow Agent shall be borne by VMARK. 8. Arbitration. Any dispute under this Agreement, including the disagreements described in Sections 4(b) and 4(c), shall be submitted to binding arbitration proceedings to be conducted in Boston, Massachusetts in accordance with (except as otherwise provided in this Agreement) the then current Commercial Arbitration Rules of the American Arbitration Association. There shall be one arbitrator chosen from the lists of said Association in accordance with its standard procedures. In addition to resolution of a matter, the arbitrator will have the right to award injunctive relief and reimbursement of arbitration costs. The award and decision of the arbitrator will be conclusive and binding, judgment on the award may be entered and enforced in a court of competent jurisdiction, and each party to this Agreement waives any right to contest the validity or enforceability of such award. The foregoing shall not prevent any party hereto from seeking temporary injunctive relief or other interim remedy pending an arbitration award pursuant hereto. 9. Notices. All notices and other communications hereunder shall be in writing and shall be deemed given, effective on receipt, if delivered personally or mailed by certified mail (return receipt requested) to the parties at the following addresses (or at such other address for a party as shall be specified by like notice): If to VMARK, to: VMARK Software, Inc. 50 Washington Street Westboro, MA 01581-1021 Attention: James K.
