Such Seller is duly qualified or licensed to do business and is in good standing (where such concept is applicable) in each jurisdiction in which the character of the properties or assets owned or operated by it, or the nature of its business, makes such licensing or qualification necessary, except where the failure to be so qualified, licensed or in good standing could not reasonably be expected to, individually or in the aggregate, result in a material adverse effect on such Seller’s ability to perform its obligations under this Agreement or to consummate the Transaction.

Section 3.2. Authority; No Conflict.

(a) Such Seller has all requisite corporate, limited liability company, partnership or analogous power, capacity and authority to execute and deliver this Agreement, to perform its obligations under this Agreement and to consummate the Transaction. The execution and delivery of this Agreement by such Seller, and the consummation by such Seller of the Transaction, have been duly and validly authorized by all necessary corporate, limited liability company, partnership or analogous action, and no other action or proceeding on the part of such Seller is necessary to authorize the execution and delivery of this Agreement or to consummate the Transaction.

Documents of such Seller; (ii) contravene, conflict with, or result in a violation of any Law to which such Seller, or any of the Securities, are subject; or (iii) contravene, conflict with, or result in a violation or breach of any provision of, or the forfeiture, impairment or acceleration of rights or obligations under, or give any Person the right to declare a default or exercise any remedy under, or to accelerate the maturity or performance of, or to cancel, terminate, or modify, any contract by which such Seller’s Securities are bound; except in the cases of clauses (ii) and (iii), for such matters as would not materially adversely impact the ability of such Seller to perform its obligations under this Agreement or to consummate the Transaction.

(c) The execution and delivery of this Agreement by such Seller does not, and the consummation of the Transaction will not, require any Consent of, registration or filing with, or declaration or notification to, any Person, except for (i) applicable requirements, if any, of the Exchange Act, the Securities Act and state securities or “blue sky” laws (“Blue Sky Laws”), and (ii) such other Consents, registrations, filings, declarations or notifications the failure of which to be obtained or made would not prevent such Seller from performing its obligations under this Agreement in any material respect.

Immediately following the Closing, Purchaser will own, beneficially and/or of record, the Securities sold to Purchaser by such Seller under this Agreement, and will have good and marketable title to such Securities, free and clear of any and all Liens (other than Liens imposed by applicable securities laws). Except pursuant to this Agreement or as contemplated by the Investment Agreements, such Seller has not, directly or indirectly, granted any option, warrant or other right to any Person to acquire any of such Seller’s Securities.

(a) Following the Closing, Purchaser may issue a press release announcing the Transaction, with the timing of such press release to be determined by Purchaser in its sole and absolute discretion; provided, however, that Purchaser shall give each Seller a reasonable prior opportunity to review and comment on such press release and shall consider Sellers’ comments in good faith.

(b) Except with respect to any reporting obligations under the Securities Exchange Act of 1934, as amended (including the obligation under Item 1.01 of the Current Report on Form 8-K to disclose the identities of the parties to a material definitive agreement), Purchaser will not, and Purchaser will not permit any of its Affiliates to, use or refer to any Seller, its name or any derivation thereof, as being a party to this Agreement or as being involved in the transactions contemplated by this Agreement (other than to the extent expressly contained in the Company’s filings with the SEC on or before the date hereof) including, without limitation, in any filing with any Governmental Body, any press release, any public announcement or statement, advertisement or in any interview or other discussion with any

Section 5.3. Further Assurances. Each Seller, as to itself, on the one hand, and Parent and Purchaser, on the other hand, agree that subsequent to the Closing Date, at the request of the other party or parties, they will execute and deliver, or cause to be executed and delivered, to the other party or parties such further instruments and take such other action as may be necessary or desirable to carry out the Transaction or to vest, perfect or confirm ownership of the Securities in Purchaser.

Section 5.4. General Release. Effective as of the Closing:

Section 6.2. Fees, Expenses and Taxes. All fees, expenses and Taxes incurred in connection with this Agreement and the Transaction shall be paid by the party incurring such fees, expenses, or Taxes.

Section 6.3. Amendment. This Agreement may not be amended, except by an instrument in writing signed by or on behalf of Purchaser and each of the Sellers.

Section 6.4. Waiver. Neither any failure nor any delay by any party in exercising any right, power or privilege under this Agreement or any of the documents referred to in this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by Law, (i) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (ii) no notice to or demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

Section 6.5. Entire Agreement. This Agreement (including the exhibits, annexes and appendices hereto), the CVR Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein constitute the entire agreement among the parties to this Agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof.

Section 6.6. Counterparts; Electronic Delivery.

(a) This Agreement may be executed in several counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original and all of which shall together constitute one and the same instrument, and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties.

Section 6.7. Governing Law. Except to the extent that the corporate laws of the State of Delaware apply to a party, this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.

The consents to jurisdiction set forth in this paragraph shall not constitute general consents to service of process in the State of Delaware and shall have no effect for any purpose, except as provided in this paragraph and shall not be deemed to confer rights on any person other than the parties hereto. Each of the parties hereto agrees that a final judgment in any such action, proceeding or counterclaim shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Section 6.9. WAIVER OF JURY TRIAL.

Section 6.10. Attorneys’ Fees. In any action at law or suit in equity to enforce this Agreement or the rights of any of the parties hereunder, and except as provided in Section 6.2, the prevailing party in such action or suit (as determined in a final, non-appealable decision by a court of competent jurisdiction) shall be entitled to receive a reasonable sum for its fees (including reasonable attorneys’ fees), costs and expenses incurred in such action or suit.

Any attempted assignment of this Agreement or of any such rights by any party without such consent shall be void and of no effect. Subject to the preceding two sentences, this Agreement shall be binding upon, and shall be enforceable by and inure to the benefit of, the parties hereto and their respective successors and assigns.

Section 6.12. No Third Party Rights. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; provided, however, that the Released Parties (with respect to their rights under Section 5.4) shall be intended third party beneficiaries.
