Capitalized terms not defined herein have the meanings ascribed to such terms in the Agreement and Plan of Merger dated of even date herewith (as the same may be amended from time to time, the “Merger Agreement”) by and among Parent, Sub and Versata, Inc., a Delaware corporation (the “Company”).

THE PARTIES ENTER THIS AGREEMENT ON THE BASIS OF THE FOLLOWING FACTS, UNDERSTANDINGS AND INTENTIONS:

A. Parent, Sub and the Company propose to enter into the Merger Agreement, which provides for Parent to make a cash tender offer (the “Tender Offer”) to purchase all of the outstanding shares of Company Common Stock, including the Shares beneficially owned (as hereinafter defined) by each Stockholder, and the merger of Sub with and into the Company (the “Merger”), upon the terms and subject to the conditions of the Merger Agreement;

B. As of the date hereof, each Stockholder is the beneficial owner (“beneficial owner,” “beneficial ownership,” “beneficially,” and related terms, wherever used herein, within the meaning of Section 13(d)(1) of the Exchange Act, but shall exclude any Shares issuable pursuant to outstanding options not exercised prior to the completion or expiration of the Tender Offer) and the owner of record of the number of shares and percentage of ownership of Company Common Stock, set forth opposite such Stockholder’s name on Exhibit A hereto; and

C. As a condition to their willingness to enter into the Merger Agreement, Parent and Sub have required each Stockholder to agree, and, in order to induce Parent and Sub to enter into the Merger Agreement each Stockholder, in such Stockholder’s capacity as a stockholder of the Company, is willing to agree, severally and not jointly, to (a) tender all Shares beneficially owned by such Stockholder (as to each Stockholder, the “Owned Shares”) into the Tender Offer; (b) grant to each of Parent and Sub the Option (defined below); and (c) grant Parent an irrevocable proxy in respect of such Owned Shares in connection with certain matters, in each case as more fully described in this Agreement, and to agree to such other matters as are set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein and in the Merger Agreement, the parties hereto agree as follows:

ARTICLE I

TRANSFER, TENDER AND VOTING OF SHARES

1.1 No Transfer; Other Actions.

(a) Without the prior written consent of Parent or as expressly contemplated hereby, from the date hereof until the Outside Date, each Stockholder agrees not to (directly or indirectly) (i) sell, transfer, pledge, assign, encumber (or suffer to exist any encumbrances) or otherwise dispose of or hypothecate (including in each case by gift or contribution, distribution to or from any trust or similar instrument, merger, consolidation, testamentary disposition, interspousal disposition pursuant to a domestic relations proceeding or otherwise or otherwise provided by law) (collectively, “Transfer”) any of such Stockholder’s Owned Shares; (ii) grant any proxy, power-of-attorney or other authorization or consent with respect to any of such Stockholder’s Owned Shares; (iii) deposit any of such Stockholder’s Owned Shares into a voting trust or enter into a voting agreement, arrangement or understanding with respect to any of such Stockholder’s Owned Shares or grant any proxy with respect thereto; (iv) enter into any Contract, option or other arrangement or undertaking (including any profit sharing arrangement) with respect to any of the items referred to in the foregoing clauses (i) through (iii); (v) acquire beneficial ownership of additional Shares (by exercise of any option, exchange, conversion of any right or otherwise); or (vi) knowingly take or cause the taking of any other action that would make such Stockholder’s representations and warranties contained herein incorrect or restrict, limit or interfere with the performance of such Stockholder’s obligations hereunder or the transactions contemplated hereby.

(b) Each Stockholder hereby authorizes and requests Parent or Sub to notify the Company’s transfer agent that there is a stop transfer order with respect to all of such Stockholder’s Owned Shares and that this Agreement places limits on the voting of all such Owned Shares; provided, however, that any such stop transfer order shall terminate upon the termination of this Agreement pursuant to Section 4.11 hereof.

1.2 Tender of Shares.

(a) Subject to Section 1.4 and Section 1.6 hereof, each Stockholder agrees that such Stockholder shall tender or cause to be tendered in the Tender Offer, prior to the Outside Date, all of such Stockholder’s Owned Shares as of the date hereof and any and all Shares such Stockholder may acquire prior to the expiration of the Tender Offer and that it shall not withdraw or cause to be withdrawn any such Shares so tendered. Each Stockholder hereby acknowledges and agrees that the obligation of Parent to commence the Tender Offer and accept for payment and pay for such Shares in the Tender Offer is subject to the terms and conditions set forth in Annex A to the Merger Agreement and subject to applicable law. In addition, each Stockholder hereby severally and not jointly grants to each of Parent and Sub an irrevocable option (as to each Stockholder, the “Option”) to purchase any or all of such Stockholder’s Owned Shares at a price per share equal to an amount not less than that which is offered in the Tender Offer. Subject to Section 4.11 hereof, the Option may be exercised at any time and from time to time after the date hereof and prior to the later of the expiration (as such date could be extended

2

pursuant to the Merger Agreement) or termination of the Merger Agreement and Tender Offer; provided, however, that the Option shall only be exercisable if Parent reasonably determines in good faith that the Minimum Condition would be met after giving effect to (i) the sale of all Shares properly tendered but not withdrawn in the Tender Offer and (ii) all other exercises (if any) of the Option with respect to the Shares for which the Parent intends to exercise the Option. If Parent shall for any reason have increased the price per share payable in the Tender Offer over the original Offer Price (and Parent accepts Shares for payment pursuant to the Tender Offer), then, immediately following payment by Parent for the Shares pursuant to the Tender Offer, each Stockholder shall pay to such Parent on demand an amount in cash equal to the product of (i) the number of such Stockholder’s Owned Shares purchased pursuant to the Tender Offer and (ii) the excess of (A) the per share cash consideration received by such Stockholder as a result of the Tender Offer, as amended, less (B) the original Offer Price.

(b) As of the date hereof, each Stockholder that has any currently exercisable options outstanding has currently exercisable options outstanding for such number of shares of Company Common Stock as set forth opposite such Stockholder’s name on Exhibit A hereto and no Stockholder has any options, warrants, or other rights exercisable, convertible, or exchangeable for any Shares that are not set forth opposite such Stockholder’s name on Exhibit A hereto.

(c) Each Stockholder hereby agrees to permit Parent and Sub to publish and disclose in the Tender Offer Material, and if required under applicable law, the Proxy Statement (including all documents and schedules filed with the SEC) such Stockholder’s identity and ownership of Company Common Stock and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement.

1.3 Voting of Shares.

(a) Subject to Section 1.4 and Section 1.6 hereof, each Stockholder, by this Agreement, at every annual, special, postponed or adjourned meeting of the stockholders of the Company called, and at every postponement or adjournment thereof, irrevocably agrees to vote any and all of such Stockholder’s Owned Shares entitled to be voted thereat or to cause any and all such Owned Shares to be voted: (i) in favor of the adoption of the Merger Agreement and approval of the Merger and the other Contemplated Transactions, (ii) against (a) any proposal for any merger, consolidation, recapitalization, sale of assets or other business combination (other than the Merger) between the Company and any Person (other than Parent or Sub), (b) any Acquisition Proposal or any Alternative Transaction (other than a Superior Proposal), (c) any change in the Company’s capital structure or any amendment of the Company’s Certificate of Incorporation or Bylaws, or (d) any other action or agreement intended to or that could result in (x) a breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement, (y) any of the conditions to the Company’s obligations under the Merger Agreement not being fulfilled, or (z) a delay of completion of the Tender Offer and/or the Merger, and (iii) in favor of any other matter relating to the consummation of the transactions contemplated by the Merger Agreement. Each Stockholder further agrees to cause such Stockholder’s Owned Shares to be voted in accordance with the foregoing. Each Stockholder acknowledges receipt and review of a copy of the Merger Agreement.

(b) Subject to Section 1.4 and Section 1.6 hereof, in furtherance of the agreements contained in Section 1.3(a) hereof and as security for such agreements, each Stockholder hereby irrevocably appoints Parent and Sub, or any nominee designated by Parent or Sub, and each of them individually, as the sole, exclusive, true and lawful Proxy (the “Proxy”) of such Stockholder, to vote each of such Stockholder’s Owned Shares as the Proxy of such Stockholder, for and in the name, place and stead of such Stockholder, with full power of substitution and resubstitution, (i) in favor of the adoption of the Merger Agreement and approval of the Merger and the other Contemplated Transactions, (ii) against any matter referred to in Section 1.3(a)(ii) of this Agreement, (iii) in favor of any other matter relating to consummation of the Contemplated Transactions, and (iv) in the discretion of the Proxy, with respect to any proposed postponements or adjournments of any annual or special meeting of the stockholders of the Company held in connection with any of the foregoing. Each Stockholder hereby affirms and agrees that the irrevocable proxy set forth in this Section 1.3(b) is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Each Stockholder hereby further affirms and agrees that the irrevocable proxy is coupled with an interest and, except as set forth in this Section 1.3(b) or Section 1.4 and Section 1.6 hereof, is intended to be irrevocable in accordance with the provisions of Section 212 of the DGCL. If for any reason the Proxy granted herein is not irrevocable, then such Stockholder agrees that it shall vote such Stockholder’s Owned Shares in accordance with Section 1.3(a) hereof as instructed by Parent in writing. Each Stockholder shall promptly deliver to Parent any proxy cards that such Stockholder receives with respect to the voting of the Company Common Stock. Each Stockholder hereby represents that any proxies heretofore given in respect of such Stockholder’s Owned Shares, if any, are revocable, and hereby revokes such proxies.

1.4 Limitation Upon Obligation to Tender and Voting Proxy. The obligations of each Stockholder specified in this Agreement shall apply whether or not (a) a Company Adverse Recommendation Change shall have occurred or (b) the Company breaches any of its representations, warranties, agreements or covenants set forth in the Merger Agreement. Parent acknowledges and agrees that this Agreement shall not be binding upon the Stockholders in the event that the Merger Agreement shall be amended by the parties thereto to lower the price or value of, or change the form of, the Offer Price.

1.5 No Solicitation.

(a) Each Stockholder agrees, in such Stockholder’s capacity as a stockholder of the Company, that it shall not, directly or indirectly, solicit, initiate, knowingly encourage or take any other action designed to facilitate any inquiries or the making of any proposal from any person (other than Parent or Sub) or offer that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal, or participate in any discussions or negotiations regarding any Acquisition Proposal.

4

(b) Each Stockholder shall notify Parent promptly of any Acquisition Proposal or any inquiry with respect to, or that could reasonably be expected to lead to, any Acquisition Proposal, in any such notice to Parent and Sub, indicate in reasonable detail the identity of the person making such proposal or inquiry and the material terms and conditions of any such Acquisition Proposal.

1.6 Fiduciary Duties. The parties acknowledge and agree that nothing contained in this Agreement shall restrict, limit or prohibit any Stockholder who is a director of the Company, from exercising in his capacity as a director of the Company his fiduciary duties as such a director, including, but not limited to, taking any action permitted pursuant to Section 6.02 of the Merger Agreement.
