“Abandonment of Belgium Transaction. Notwithstanding anything to the contrary in this Agreement, the sale, transfer and conveyance by Seller, and the purchase of the Belgium Purchased Entity Equity by MSC Software Benelux following the Closing pursuant to the terms hereof (the “Belgium Transaction”), may be abandoned at any time prior to the Belgium Closing:

(b)by Seller or by Purchaser via written notice to the other Party, if the Belgium Closing shall not have occurred on or prior to the Belgium Outside Date (as may be extended); provided, that the right to terminate the Belgium Transaction under this Section 8.4(b) shall not be available to any Party whose failure to perform any covenant or obligation under this Agreement or material breach of any representation or warranty herein has been the primary cause of the failure of the Belgium Closing to occur on or before such date; or

(c)by Seller or by Purchaser via written notice to the other Party, if there shall be enacted any Law or is any final and non-appealable Judgment issued after the date hereof enjoining, prohibiting or rendering illegal the consummation of the Belgium Closing; provided that the right to terminate this Agreement pursuant to this Section 8.4(c) shall not be available to any Party whose breach of any representations, warranty, covenant or agreement set forth in this Agreement has been the primary cause of the issuance, promulgation, enforcement or entry of such Law or Judgment.

“(i) solicit or recruit, or attempt to solicit or recruit, for employment or engagement (whether as an employee, contractor, consultant or otherwise) any individual employed or engaged by Seller or its Affiliates (other than, if the Closing occurs, the Transferred Entities or any Business Employees or individuals who are Excluded Entity Personnel as of the date hereof or as of Closing, or if the Belgium Transaction is abandoned in accordance with Section 8.4, Business Employees of the Belgium Purchased Entity) whom Purchaser or its Affiliates were first introduced to or made aware of in

9.Employee Matters. The first sentence of Section 5.7(a) of the Agreement is hereby amended by replacing “With respect to each Business Employee who continues in employment with a Transferred Entity as of immediately following the Closing (a “Continuing Employee”)” with “With respect to each Business Employee who continues in employment with a Transferred Entity as of immediately following the Closing or immediately following the Belgium Closing, as applicable (a “Continuing Employee”)”.

(e)From and after the Closing until the earlier to occur of the Belgium Closing and the abandonment of the Belgium Transaction pursuant to Section 8.4, Purchaser shall, and shall cause its Affiliates to, continue to own, directly or indirectly, all, and shall not transfer, sell or otherwise grant to any third party any interest in or to any, of the outstanding equity interests of MSC Software Benelux.

11.Waiver of Closing Condition. The Parties hereby waive the Belgium Approval as a condition to Closing for purposes of Section 7.1(a)(ii) of the Agreement (it being understood that the Belgium Approval will be required prior to the Belgium Closing).

“Following the Closing until the earlier of the Belgium Closing and the abandonment of the Belgium Transaction pursuant to Section 8.4, the Parties will cooperate in good faith to identify any additional services which may be required under the Transition Services Agreement to enable Seller to operate the Belgium Purchased Entity and the portion of the Business conducted by the Belgium Purchased Entity or for Purchaser to operate the portion of the Business transferred at Closing, subject to applicable Law, in each case in the ordinary course of business consistent with past practice during the period between the Closing and the earlier of the Belgium Closing and the abandonment of the Belgium Transaction pursuant to Section 8.4 in accordance with the terms hereof, and such services shall be added as Purchaser Services or Seller Services, as applicable. For the avoidance of doubt, for purposes of the Transition Services Agreement, until the Belgium Closing, the Belgium Purchased Entity shall be an Affiliate of Seller.”

(a)Seller shall, or shall cause its applicable Affiliate to, promptly pay or deliver to Purchaser (or its designated Affiliate) any monies or checks or other Cash Amounts that are in respect of the Business that have been delivered to, received by or otherwise identified in the possession of Seller or any of its Affiliates either after the Closing or, with respect to the Belgium Purchased Entity, the Belgium Closing, including any monies or checks or other Cash Amounts sent by customers, suppliers or other contracting parties in respect of the Business.

This Amendment shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In addition, each of the Parties (i) irrevocably submits to the personal jurisdiction of the Delaware Court of

The waiver by any Party of a breach, failure or default of any term or provision of this Amendment shall not be construed as a waiver of, or estoppel with respect to, any subsequent breach, failure or default unless expressly identified by such written waiver. No failure or delay by any Party in exercising any right, remedy, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Accordingly, the Parties acknowledge and agree that the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of this Amendment and to enforce specifically the terms and provisions hereof without proof of actual damages or the inadequacy of monetary relief, in addition to any other remedy to which such Party is entitled in Law or in equity. Each Party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other Party has an adequate remedy at Law or that any award of specific performance is not an appropriate remedy for any reason at Law or in equity. Any Party seeking an injunction or injunctions to prevent breaches or threatened breaches of this Amendment or to enforce specifically the terms and provisions of this Amendment shall not be required to provide any bond or other security in connection with such remedy. The foregoing is in addition to any other remedy to which any Party is entitled at Law, in equity or otherwise, including monetary damages.
