ARTICLE V1 CERTAIN POST-CLOSING COVENANTS ------------------------------ 6.1 Seller Use of Buyer Emulation Services. -------------------------------------- (a) Seller agrees that when it is in need of emulation services either internally or with respect to a customer project, it will, where feasible, first offer Buyer the opportunity to undertake the project, giving Buyer a clear indication of the nature and timing of the project. In determining whether it has the resources available to undertake the project according to Seller's desired schedule, Buyer will give Seller's project priority status over projects of similar size (measured in realizable revenues) and schedule (measured in terms of timing to completion), unless in Buyer's reasonable judgment doing so will cause Buyer undue commercial harm. Buyer will in no event be required to divert resources from an existing project on Seller's behalf Buyer will notify Seller in writing of its determination whether to accept a particular project as promptly as is practicable, with a brief explanation of any refusal. If Buyer agrees to undertake the project, it will do so on terms no less favorable than with respect to other current projects of similar size and schedule. (b) Buyer agrees to sell its emulation products to Seller (1) for Seller's internal use (which shall not involve the provision of design or other services to others), and (ii) for Seller's use in a discrete design services consulting project, it being understood that following completion of such project, all Buyer emulation products used in connection with such project can be used thereafter only in Seller internal projects unless a Vice President of Buyer consents in writing to use in connection with a specific project. Such consent of a Vice President of Buyer must be obtained with respect to each subsequent project with respect to which the same Buyer emulation products are proposed to be used. 6.2 Noncompetition. -------------- (a) Neither Seller nor any of its affiliates, subsidiaries, or similarly controlled entities, shall, during the period commencing on the Closing Date and ending on the fifth 14 anniversary of the Closing Date, directly or indirectly engage in the integrated circuit emulation business anywhere in the world. The foregoing restriction shall include without limitation any investment of cash or other property, loan, joint venture, strategic alliance, license or other similar business arrangement relating to the integrated circuit emulation business, but shall not include Seller actions required to satisfy its service and support requirements pursuant to Section 6.3. In the event that Seller is acquired (whether through (i) sale of substantial assets, or (ii) merger, sale of stock or otherwise pursuant to which the shareholders immediately prior to such transaction hold less than a majority of the voting securities of the surviving or acquiring corporation after such transaction) by an entity with significant operations relating to the integrated circuit emulation business at the time of such transaction (a "Pre-Existing Emulation Business"), this prohibition shall not apply to the Pre-Existing Emulation Business. (b) Neither Buyer nor any of its affiliates, subsidiaries or similarly controlled entities shall, during the period commencing on the Closing Date and ending on the fifth anniversary of the Closing Date, directly or indirectly engage in the commercial logic synthesis business, relating to integrated circuit design creation (the "Synthesis Business"). The foregoing restriction shall include, without limitation, any investment of cash or other property, loan, joint venture, strategic alliance, license or other similar business arrangement relating to the Synthesis Business. In the event that Buyer is acquired (whether through (i) sale of substantial assets or (ii) merger, sale of stock or otherwise pursuant to which the shareholders immediately prior to such transaction hold less than a majority of the voting securities of the surviving or acquiring corporation after such transaction) by an entity with significant operations relating to the Synthesis Business at the time of such transaction (a "Pre-Existing Synthesis Business"), this prohibition shall not apply to the Pre-Existing Synthesis Business. (c) The parties agree that the covenants set forth in Sections 6.2(a) and 6.2(b) above are a material and substantial part of this Agreement. Because of the difficulty of measuring economic losses to the nonbreaching party as a result of a breach of the restrictive covenants set forth in Sections 6.2(a) and 6.2(b) above, and because of the immediate and irreparable damage that would be caused to the nonbreaching party by such breach, for which monetary damages would not be a sufficient remedy, the parties agree that in addition to all other remedies that may be available to the nonbreaching party at law or in equity, the nonbreaching party shall be entitled to specific performance and any injunctive or other equitable relief as a remedy for any breach or threatened breach of such restrictive covenant, 6.3 Buyer Support of Seller Emulation Business Customers. Buyer agrees ---------------------------------------------------- to provide service and support under the terms of its standard service and support agreements to each customer of the Seller Emulation Business (excluding customer sites at which equipment has been installed by Seller for free, or for which there is no Seller record of a revenue transaction or backlog), which agrees to terminate its existing support and service agreements with Seller or Sub and waive any remaining fights or claims thereunder or otherwise relating to support of such customer as a customer of the Seller Emulation Business in exchange for (i) replacement of its existing Sub emulation products with reasonably comparable Buyer emulation products, and (ii) Buyer entering into its standard service and support agreement with such customer (such exchange being referred to herein as the "Swap Arrangement"), but only as to those customers which accept the Swap Agreement prior to September 30, 1997. Seller's intent is that, until a 15 particular customer of the Seller Emulation Business accepts the Swap Arrangement (including the waiver by such customer of any remaining rights or claims under existing support and service agreements with Seller or Sub or otherwise relating to support of such customer as a customer of the Seller Emulation Business), Seller would, to the extent practicable, satisfy all service and support requirements of such customer in accordance with the terms of its existing support and service arrangements with such customer. Seller acknowledges that it may be required to satisfy such support and service requirements for an indefinite period which may exceed the duration of the term of the customer's existing support and service arrangements. Seller will inform Buyer when it believes it has completed its support of any customer. The parties acknowledge that Buyer shall have no obligation to a particular customer of the Seller Emulation Business other than to offer to enter into the Swap Arrangement and, only if such arrangement is agreed to by the customer prior to September 30, 1997, to fulfill the terms of such arrangement. In addition, with regard to each maintenance contract for which revenue has been deferred and as to which Buyer and the party to such maintenance contract have entered into the Swap Arrangement, Seller and Sub agree to return the unearned deferred maintenance amounts to the applicable customer. 6.4 License of Intellectual Property and Provision of Equipment for --------------------------------------------------------------- Support Services. ---------------- (a) Buyer hereby grants to Seller, for a period of one year from the date of this Agreement, a limited, nontransferable license (with no right to sublicense) to use the Intellectual Property, but solely for the purpose of providing support to Seller's customers as envisioned in Section 6.3 Buyer agrees that Seller may retain such number of copies of the software, documentation and other materials (excluding hardware) included in the Acquired Assets as are reasonably necessary to provide such support. (b) Buyer will provide Seller, for a period of one year from the date of this Agreement, at no charge, with at least one complete Seller emulation system, including hardware, software and documentation, for the purpose of providing support to Seller's customers as envisioned in Section 6.3, and will provide such additional systems as the parties may agree are reasonably necessary to carry out the purposes of Section 6.3 (keeping in mind their mutual goal to encourage customers to accept the Swap Arrangement). (c) Buyer will provide Seller, for a period of one year from the date of this Agreement, at no charge, such parts and equipment as Seller may require in fulfilling its support obligations as envisioned in Section 6.3, provided that Seller provides such parts and equipment to its customers without charge. To the extent that Seller sells any such equipment to its customers (e.g., for a system upgrade or capacity increase), the proceeds of such sale shall be passed on to Buyer. In addition, any new revenue recovered by Seller subsequent to the date of this Agreement from the end user as part of the ongoing process of maintenance and service will be passed on to Buyer. (d) Upon the termination of all support services by Seller as envisioned in Section 6.3, Seller shall notify Buyer of such termination and the license granted in Section 6.4(a) shall automatically terminate. At such time, Seller shall return all tangible materials 16 licensed or supplied by Buyer under this Section 6.4 and shall destroy all intangible copies of such materials in its possession. 6.5 Patent License Back. ------------------- (a) For purposes of this Section 6.5, "Transferred Patents" means the patents issuing from the applications listed in Schedule 1.2 or another application derived directly or recursively from such applications as a division, a continuation, a continuation-in-part, or a foreign counter-part of such applications. (b) For purposes this Section 6.5 Simulation Software means a computer program owned by Seller that operates on a general purpose computer for simulation or analyzing the behavior of digital circuits and systems, provided that such software does not perform or control emulation. (c) Buyer grants Seller a worldwide, non-exclusive, non-transferable (except as set forth in this Section 6.5), royalty-free rights and license (without right to sublease except as set forth in this Section 6.5) under the Transferred Patents to make, use, sell, offer for sale or import Simulation Software. Seller may license third Parties to use Simulation Software under the Transferred Patents in the ordinary course of Seller's business. Seller may transfer this license to a third party in the event that Seller disposes of all or substantially all of its assets or business related to Simulation Software. Seller may not otherwise transfer or sublicense the Transferred Patents. ARTICLE VII ESCROW INDEMNIFICATION ---------------------- 7.1 Escrow Fund. As soon as practicable after the Closing, the Escrow ----------- Amount shall be deposited with The First National Bank Boston (or other institution selected by Buyer with the reasonable consent of Seller) as escrow agent (the "Escrow Agent"), such deposit to constitute the Escrow Fund and to be governed by the terms set forth herein and in the Escrow Agreement attached hereto as Exhibit A. The Escrow Fund shall be available to compensate Buyer --------- pursuant to the indemnification obligations of Seller set forth in this Agreement, with respect to Damages (as defined below) arising by reason of Seller's failure to deliver any of the Acquired Assets. The Escrow Fund shall act as partial security for Seller's and Sub's indemnification obligations set forth in this Agreement, but shall not serve as Buyer's exclusive remedy with respect thereto. The Escrow Fund shall be released upon the later of (i) June 27, 1997 and (ii) completion of delivery of all Acquired Assets by Seller to Buyer, as provided in and subject to the terms of the Escrow Agreement. 7.2 Indemnification. --------------- (a) Subject to the limitations set forth in this Article VII, Seller will defend, indemnify and hold harmless Buyer and its respective officers, directors, agents and employees, and each person, if any, who controls or may control Buyer within the meaning of the Securities 17 Act (individually, an "Indemnified Person" and collectively "Indemnified Persons") and shall reimburse Indemnified Persons, for, from and against any and all losses (which shall include any diminution in value), costs, damages, liabilities and expenses arising from claims, demands, actions and causes of action, including, without limitation, reasonable legal fees, (collectively, "Damages") arising out of (i) any misrepresentation or breach of or default in connection with any of the representations, warranties, covenants and agreements given or made by Sub or Seller in this Agreement, or any exhibit or other schedule to this Agreement, or (ii) transactions, events, acts or omissions of or by Seller or Sub relating to the Seller Emulation Business on or before the Closing (including without limitation any claim or infringement (i) as a result of the inaccuracy of the representation set forth in Section 2.12(a) without regard to the knowledge qualifier and (ii) which relates to actions or events occurring prior to the date of the Agreement). (b) Subject to the limitations set forth in this Article VII, Buyer shall defend indemnify and hold harmless each Indemnified Person and shall reimburse Indemnified Persons for, from and against all Damages arising out of any misrepresentation or breach of or default in connection with any of the representation, warranties, covenants or agreements given or made by Buyer in this Agreement or any exhibit or other schedule to this Agreement. (c) Buyer and Seller each acknowledge that such Damages, if any, would relate to unresolved contingencies existing at the Closing, which if resolved at the Closing would have led to a reduction in the total purchase price. Buyer would have agreed to issue in connection with the Acquisition. Accordingly, Seller agrees that at the sole election of Buyer, certain warrants may become unexercisable and/or be cancelled in accordance with the provisions of the Buyer's Warrant. 7.3 Indemnification Procedure. All claims for indemnification under this ------------------------- Article VII (individually, a "Claim" and collectively, "Claims") shall be asserted and resolved as follows: (a) In the event that any claim for which Seller or Sub, as the case may be (the "Indemnifying Party"), would be enable to indemnify an Indemnified Person hereunder is asserted which Claim does not involve a Claim being asserted against or sought to be collected by a third party, the Indemnified Person shall with reasonable promptness send a Claim Notice (as defined in Section 7.3(b) below) with respect to such Claim to the Indemnifying Party. If the Indemnifying Party does not notify the Indemnified Person within 30 days from the date of receipt of such Claim Notice that the Indemnifying Party disputes such Claim, the amount of such Claim shall be conclusively deemed a liability of the Indemnifying Party hereunder. In case the Indemnifying Party shall object in writing to any Claim made in accordance with this Section 7.3(a), the Indemnified Person shall have fifteen (15) days to respond in a written statement to the objection of the Indemnifying Party. If after such fifteen (15) day period there remains a dispute as to any Claims, the parties shall attempt in good faith for sixty (60) days to agree upon the rights of the respective parties with respect to each of such Claims. If the parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties. (b) In the event that any Claim for which an Indemnifying Party would be liable to an Indemnified Person hereunder is asserted against an Indemnified Person by a third party, the Indemnified Person shall with reasonable promptness notify the Indemnifying Party of 18 such Claim including a copy of the Claim made if the Claim was made in writing, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such Claim) (the "Claim Notice"). The Indemnifying Party shall have 30 days from the receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Person (i) whether or not the Indemnifying Party disputes the Indemnifying Party's liability to the Indemnified Person hereunder with respect to such Claim and (ii) if the Indemnifying Party does not dispute such liability, whether or not the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend against such Claim, provided that the Indemnifying Party is hereby authorized (but not obligated) prior to and during the Notice Period to file any motion, answer or other pleading and to take any other action which the Indemnifying. Party shall deem necessary or appropriate to protect the Indemnifying Party's interests. In the event that the Indemnifying Party notifies the Indemnified Person within the Notice Period that the Indemnifying Party does not dispute the Indemnifying Party's obligation to indemnify hereunder and desires to defend the Indemnified Person against such Claim and except as hereinafter provided, the Indemnifying Party shall have the right to defend by appropriate proceedings, which proceedings shall be diligently settled or prosecuted by the Indemnifying Party to a final conclusion; provided that, unless the Indemnified Person otherwise consents in writing, which consent shall not be unreasonably withheld, the Indemnifying Party may not settle any matter (in whole or in part) unless such settlement includes a complete and unconditional release of the Indemnified Person. If the Indemnified Person desires to participate in, but not control, any such defense or settlement the Indemnified Person may do so at the Indemnified Person's sole cost and expense. If the Indemnifying Party elects not to defend the Indemnified Person against such Claim, whether by failure of the Indemnifying Party to give the Indemnified Person timely notice as provided above or otherwise, then the Indemnified Person, without waiving any rights against the Indemnifying Party, may settle or defend against any such Claim in the Indemnified Person's sole discretion and if it is determined that the Indemnifying Party is responsible therefore under this Article VII, the Indemnified Person shall be entitled to recover from the Indemnifying Party the amount of any settlement or judgment and, on an ongoing basis, all indemnifiable costs and expenses of the 1ndemnified Person with respect thereto, including interest from the date such costs and expenses were incurred. (c) The Indemnified Person's failure to give reasonably prompt notice to the Indemnifying Party of any actual, threatened or possible claim or demand which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which the Indemnifying Party may have to the Indemnified Person unless the failure to give such notice materially and adversely prejudiced the Indemnifying Party. ARTICLE VIII CERTAIN TAX MATTERS ------------------- Buyer and Seller hereby covenant and agree with respect to certain tax matters as follows: 8.1 Returns; Indemnification; Liability for Taxes. --------------------------------------------- 19 (a) Seller shall prepare and file (or cause to be prepared and filed) on a timely basis all Tax Returns with respect to Sub and its subsidiaries for all taxable periods ending on or before the Closing Date ("Sub Tax Returns") and shall pay, and shall indemnify and hold Buyer harmless against and from (i) all Taxes of Sub and its subsidiaries for all taxable years or periods which end on or before the Closing Date; (ii) all Taxes for all taxable years or periods of all members subsidiaries of any affiliated group. of which Sub and any of its subsidiaries is or has been a member prior to the Closing Date; and (iii) with respect to any taxable period commencing before the Closing Date and ending after the Closing Date (a "Straddle Period") all Taxes of Sub and its subsidiaries attributable to the portion of the Straddle Period prior to and including the Closing Date (the "Pre-Closing Period").

If as a result of such Changes, Buyer or its subsidiaries enjoy a net Tax benefit from an increase in deductions, losses or tax credits and/or a decrease in income, gains, premiums, revenues or recapture of tax credits ("Buyer Benefits") for taxable periods ending after the Closing Date, Buyer shall pay to Seller the amount of such Buyer Benefit, as and when such Buyer Benefits are realized by Buyer in accordance with Section 8.2(d). (c) If an audit examination of any Tax Return of Buyer or its subsidiaries for taxable periods ending after the Closing Date shall result (by settlement or otherwise) in any Change reflected on a Tax Return of Seller or its subsidiaries for any taxable periods ending on or before the Closing Date, Buyer will notify Seller and provide it with all necessary information so that Seller can reflect any appropriate Changes on its Tax Return. If as a result of such Changes, Seller or its subsidiaries enjoy a net Tax benefit from an increase in deductions, losses or tax credits and/or a decrease in the income, gains, premiums, revenues or recapture of tax credits ("Seller Benefits") for taxable periods ending on or before the Closing Date, Seller shall pay to Buyer the amount of such Seller Benefits as and when such Seller Benefits are realized by Seller, in accordance with Section 8.2(d). (d) Any payments of refunds or credits for Taxes, or any payment of Buyer Benefits or Seller Benefits, that are required to be paid under this Agreement shall be made within 10 business days of the receipt of any refund or 30 Business Days of the realization of any tax benefit, as the case may be. Any payments not made within such time period, shall be subject to an interest charge of 12% per annum. 8.3 Termination of Tax Sharing Agreements.

Each party shall promptly forward to the other in accordance with Section 9.2 all written notifications and other written communications, including if available the original envelope showing any postmark, from any taxing authority received by such party or its affiliates relating to any liability for Taxes for any taxable period for which such other party or any of its affiliates is charged with payment or indemnification responsibility under this Agreement and each indemnifying party shall promptly notify, and consult with, each indemnified party as to any action it proposes to take with respect to any liability for Taxes for which it is required to indemnify another party and 21 shall not enter into any closing agreement or final settlement with any Taxing Authority with respect to any such liability without the written consent of the indemnified parties, which consent shall not be unreasonably withheld.
