Stockholder hereby irrevocably and unconditionally waives, and agrees to cause to be waived and to prevent the exercise of, any rights of appraisal, any dissenters’ rights and any similar rights relating to the Merger or any related transaction that Stockholder or any other Person may have by virtue of, or with respect to, any shares of Common Stock Owned by Stockholder (including any and all such rights under Section 262 of the DGCL).

Stockholder agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, that may be brought against the Company, Buyer, Merger Sub, or any of their respective successors and assigns relating to the negotiation, approval, execution or delivery of this Agreement, the Merger Agreement, the Merger or the consummation of the transactions contemplated hereby and thereby (including, for the avoidance of doubt, any claims alleging a breach of fiduciary duty by the Board of the Directors of the Company or breaches of federal securities law in connection with any of the foregoing and any claim seeking to enjoin or delay the consummation of the Merger).

Such Stockholder shall cease immediately any solicitations, encouragement, discussions and negotiations by such Stockholder, its Affiliates or its Representatives that commenced prior to the date of this Agreement with respect to any Acquisition Proposal. Notwithstanding anything to the contrary provided in this Agreement, Stockholder and any of its Affiliates and Representatives shall not be prohibited from participating in any discussions or negotiations with respect to a possible tender and support, voting or similar agreement in connection with an Acquisition Proposal in the event that the Company is permitted to take the actions set forth in Section 6.10 of the Merger Agreement with respect to such Acquisition Proposal.

Nothing in this Agreement is intended to confer on any Person (other than Buyer and its successors and assigns) any rights or remedies of any nature.

8.11 Specific Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement required to be performed by either of the parties hereto were not performed in accordance with its specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. Stockholder agrees that, in the event of any breach or threatened breach by Stockholder of any covenant or obligation contained in this Agreement, Buyer shall be entitled, without any proof of actual damages (and in addition to any other remedy

that may be available to it at law or in equity, including monetary damages) to obtain: (a) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation; and (b) an injunction restraining such breach or threatened breach. Stockholder further agrees that neither Buyer nor any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 8.11, and Stockholder irrevocably waives any right Stockholder may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

In any action between any of the parties hereto arising out of or relating to this Agreement (whether at law or in equity, whether in contract or in tort or otherwise), each of the parties hereto: (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware unless (A) the federal courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware, or (B) the Chancery Court declines to accept jurisdiction over a particular matter, in which case in any other state or federal court within the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any court other than the Court of Chancery of the State of Delaware (unless (A) the federal courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware, or (B) the Chancery Court declines to accept jurisdiction over a particular matter, in which case in any other state or federal court within the State of Delaware). Service of any process, summons, notice or document to any party’s address and in the manner set forth in Section 8.06 shall be effective service of process for any such action.

The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission in .PDF format, through an electronic signature service or by facsimile shall be sufficient to bind the parties hereto to the terms of this Agreement.

8.16 Waiver. No failure on the part of Buyer to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of Buyer in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Buyer shall not be deemed to have waived any claim available to Buyer arising out of this Agreement, or any power, right, privilege or remedy of Buyer under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of Buyer; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

8.17 Independence of Obligations. The covenants and obligations of Stockholder set forth in this Agreement shall be construed as independent of any other Contract between Stockholder, on the one hand, and the Company or Buyer, on the other. The existence of any claim or cause of action by Stockholder against the Company or Buyer shall not constitute a defense to the enforcement of any of such covenants or obligations against Stockholder. Nothing in this Agreement shall limit any of the rights or remedies of Buyer under the Merger Agreement, or any of the rights or remedies of Buyer or any of the obligations of Stockholder under any agreement between Stockholder and Buyer or any certificate or instrument executed by Stockholder in favor of Buyer; and nothing in the Merger Agreement or in any other such agreement, certificate or instrument, shall limit any of the rights or remedies of Buyer or any of the obligations of Stockholder under this Agreement. Notwithstanding anything to the contrary in this Section 8.17, Stockholder will not be liable for claim, losses, damages, liabilities or other

8.18 No Agreement Until Executed; No Ownership Rights.

Nothing contained in this Agreement shall be deemed to vest in Buyer, the Company or any of their Affiliates any direct or indirect ownership of, or with respect to, the Subject Securities. All rights, ownership and economic benefits of and relating to the Subject Securities shall remain vested in and belong to the applicable Stockholder, and neither Buyer nor any of its Affiliates shall possess any power or authority to direct any Stockholder in the voting or disposition of any of the Subject Securities, except as otherwise specifically provided in this Agreement.
