1.6Advance Resignation Letters. Parent may require the Sponsor Designee, prior to or at any time after becoming a member of the Post-Closing Board of Directors, to execute and deliver an undated resignation letter (each, a “Resignation Letter”) addressed to the Secretary of Parent, which Parent agrees shall not be dated or become effective until such time as such Sponsor Designee’s resignation is required pursuant to Section 1.7(a).

1.7Removal of Directors; Obligations; Vacancies.

(a)Sponsor hereby acknowledges and agrees that, upon the occurrence of a 95% Reduction, Parent may effect the resignation of the Sponsor Designee pursuant to the dating of the Resignation Letter of such Sponsor Designee as of the date of the 95% Reduction, with such resignation deemed to have occurred, and being effective as of, such date.

(b)The obligations of the Voting Parties pursuant to this Section 1 shall include any stockholder vote approve such amendments to the Parent Certificate of Incorporation and/or Parent Bylaws as are required to effect the intent of this Agreement. Each of Sponsor, the Voting Parties and Parent agree to take all actions required to ensure that the rights given to each party hereunder are effective and that each party enjoys the benefits thereof. Each of the parties further agrees to not take any actions that would contravene or materially and adversely affect the provisions of this Agreement and the intention of the parties with respect to the composition of the Post-Closing Board of Directors as herein stated.

(c)In the event that any director elected pursuant to the terms hereof ceases to serve as a member of the Post-Closing Board of Directors, other than in connection with or following the termination of this Agreement pursuant to Section 7: (i) if such director is a Sponsor Designee, then the Voting Parties agree to vote the Voting Shares for the election or appointment to the Post-Closing Board of Directors of such other person designated by the Sponsor (a “Replacement Sponsor Designee”) in accordance with the terms provided herein; and (ii) if such director is a Company Designee, then the Sponsor agrees (A) to vote all Sponsor Shares for the election or appointment to the Post-Closing Board of Directors of such other person designated by the Company in accordance with the terms provided herein (a “Replacement Company Designee”) and (B) to use its good faith efforts to cause its Affiliates to vote all shares of voting capital stock of Parent that they own from time to time and are entitled to vote for the election or appointment to the Post-Closing Board of Directors of such Replacement Company

This Agreement has been duly executed and delivered by such Person and, assuming the due authorization, execution and delivery of this Agreement by the other parties to this Agreement, constitutes the valid and legally binding obligation of such Person, enforceable in accordance with its terms, except as enforcement may be limited by the Enforceability Exceptions.

2.3Governmental Consents and Filings. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of such Person in connection with the consummation of the transactions contemplated by this Agreement.

2.4Compliance with Other Instruments. The execution, delivery and performance by such Person of this Agreement and the consummation by such Person of the transactions contemplated by this Agreement will not result in any violation or default: (a) of any provisions of its organizational documents, if applicable; (b) of any instrument, judgment, order, writ or decree to which it is a party or by which it is bound; (c) under any note, indenture or mortgage to which it is a party or by which it is bound; (d) under any lease, agreement, contract or purchase order to which it is a party or by which it is bound; or (e) of any provision of any federal or state statute, rule or regulation applicable to such Person, in each case (other than clause (a)), which would have a material adverse effect on such Person or its ability to consummate the transactions contemplated by this Agreement.

3.Successors in Interest of the Voting Parties and Parent.

5.Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured party for the breach of this Agreement by any party hereto, that this Agreement shall be specifically enforceable, and that any breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order without the requirement to post any bond or other security or to prove that money damages would be inadequate. Further, each party hereto waives any claim or defense that there is an adequate remedy at Law for such breach or threatened breach and agrees that a party’s rights would be materially and adversely affected if the obligations of the other parties under this Agreement were not carried out in accordance with the terms and conditions hereof.

9.Severability. A determination by a court or other legal authority that any provision that is not of the essence of this Agreement is legally invalid shall not affect the validity or enforceability of any other provision hereof. The parties shall cooperate in good faith to substitute (or cause such court or other legal authority to substitute) for any provision so held to be invalid a valid provision, as alike in substance to such invalid provision as is lawful.

10.Governing Law. This Agreement and all disputes or controversies arising out of or relating to this Agreement, including the applicable statute of limitations, shall be governed by and interpreted in accordance with the Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware.

11.Counterparts; Electronic Signatures. This Agreement may be executed in any number of original, electronic or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.
