Section 2.01. Guarantee. (a) Guarantor hereby unconditionally, absolutely and irrevocably guarantees, undertakes and promises to cause, as herein provided, the due and punctual payment and the full and prompt performance by Obligor or its Affiliates of all of the amounts to be paid, including the payment of the Merger Consideration, and all of the terms and provisions to be performed or observed by or on the part of Obligor or its Affiliates, under the Merger Agreement (all such terms and provisions as now or hereafter in existence being collectively called the “Obligations”), whether according to the present terms thereof, or pursuant to any change in the terms, covenants and conditions thereof at any time hereafter made or granted, including pursuant to any amendments, extensions or renewals of the Merger Agreement or the Obligations, subject to the terms and limitations hereof and thereof. Guarantor agrees and acknowledges that no amendment, extension or renewal of the Merger Agreement (whether with or without Guarantor’s consent) or the Obligations will discharge or otherwise affect the liability of Guarantor under this Agreement.

(b) In the event that Obligor or its Affiliates shall fail in any manner whatsoever to pay, perform or observe any of the Obligations, when and as the same shall be required to be paid, performed or observed under the terms of the Merger Agreement, Guarantor will itself duly and punctually pay, or fully and promptly perform or observe, as the case may be, such Obligations, or cause the same to be duly and punctually paid, or fully and promptly performed or observed, in each case as if Guarantor were itself the obligor with respect to such Obligations under the Merger Agreement.

Section 2.02. No Demand or Notice. (a) It shall not be a condition to the guarantees and agreements set forth in Section 2.01 (the “Guarantee”) that the Company shall have first made any request of, or demand upon, or given any notice of the occurrence of a default under the Merger Agreement (unless such notice is specifically required under the Merger Agreement) or any other notice whatsoever to, Guarantor or

Obligor or its Affiliates or any other Person, or shall have instituted any action or proceeding against Obligor or its Affiliates or any other Person in respect thereof, or shall have joined Obligor or its Affiliates in any such action or proceeding.

(b) The Company, in asserting the benefit of the Guarantee shall give prompt notice to Guarantor of any failure by Obligor or its Affiliates to pay, perform or observe any Obligation; provided that any failure, delay or defect in the giving of such notice shall not alter or affect the Guarantee under this Agreement.

Section 2.03. Waiver of Resort to Security. Guarantor further agrees that this Agreement, insofar as it constitutes a guarantee of monetary Obligations, constitutes a guarantee of payment when due and not of collection, and Guarantor waives any right to require as a condition to its Guarantee that any resort be had by the Company to any security held for the payment of any Obligation.

Section 2.04. No Discharge. The Guarantee is and shall remain absolute and unconditional irrespective of any circumstance that might otherwise constitute a legal or equitable discharge of a surety or guarantor, as the case may be, with respect to its Guarantee.

Section 2.05. Waivers by Guarantor. (a) Guarantor hereby waives with respect to its Guarantee but without prejudice to the rights of the parties to the Merger Agreement, any notice of acceptance of this Agreement by the Company, grace, presentment, demand, protest, notice of the occurrence of a default under the Merger Agreement and any other notice of any kind whatsoever and promptness in making any claim or demand hereunder.

(b) The Guarantee shall not be affected by (i) the failure of the Company to assert any claim or demand or to enforce any right or remedy under the provisions of the Merger Agreement or any agreement related to the foregoing or otherwise, (ii) any extension of the Merger Agreement or any agreement related to the foregoing, (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of the Merger Agreement or of any agreement related to the foregoing, including any change in the time, manner or place of payment or performance of any of the obligations under the Merger Agreement or (iv) the release of any security held for payment of any Obligations.

Section 2.06. No Reduction. (a) The Guarantee shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever.

(b) Notwithstanding anything herein to the contrary, the Company hereby agrees that to the extent Obligor is relieved of any of its Obligations pursuant to the terms and conditions of the Merger Agreement, Guarantor shall be relieved to the same extent of its corresponding obligations under this Guarantee.

Section 2.07. Enforcement. Notwithstanding anything herein to the contrary, the Company may proceed to enforce the Guarantee against Guarantor without first pursuing or exhausting any right or remedy that the Company or any of its successors or assigns may have against Obligor or its Affiliates or any other Person.

Section 2.08. Continued Effectiveness. The Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation of Obligor or its Affiliates is rescinded or must otherwise be restored or returned by the Person receiving such payment upon the insolvency, bankruptcy or reorganization of Obligor or its Affiliates, all as though such payment or part thereof had not been made. Notwithstanding the foregoing, this Guarantee shall terminate and Guarantor shall have no further obligations under this Guarantee upon the termination of the Merger Agreement under circumstances in which the Company is entitled to retain the Parent Deposit or the Substituted Parent Deposit, as the case may be, pursuant to Section 11.04(e) of the Merger Agreement.

Section 2.09. No Recourse. Notwithstanding anything that may be expressed or implied in this Guarantee or any document or instrument delivered in connection herewith, by its acceptance of the benefits of this Guarantee, the Company covenants, agrees and acknowledges that no Person, other than Guarantor and any assignee permitted in accordance with Section 3.10, has any obligations hereunder and that, notwithstanding that Guarantor (and any assignee permitted in accordance with Section 3.10) may be a partnership or limited liability company, the Company has no right of recovery under this Guarantee, or any claim based on such obligations against, and no personal liability based on such obligations shall attach to, the former, current or future equity holders, controlling persons, directors, officers, employees, agents, Affiliates, members, managers or general or limited partners of any of Guarantor or Parent or Merger Subsidiary or any former, current or future stockholder, controlling person, director, officer, employee, general or limited partner, member, manager, Affiliate, financing source or agent of any of the foregoing, in each case, other than any assignee permitted in accordance with Section 3.10, Parent and Merger Subsidiary (each a “Non-Recourse Party”), through Parent, Merger Subsidiary or otherwise, whether by or through attempted piercing of the corporate veil, by or through a claim by or on behalf of Parent or Merger Subsidiary against any Non-Recourse Party, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or Applicable Law, or otherwise, and the Company further covenants, agrees and acknowledges that the only rights of recovery that the Company has in respect of the Merger Agreement or the transactions contemplated thereby are its rights to recover from Parent and Merger Subsidiary under and to the extent expressly provided in the Merger Agreement and its right to recover from Guarantor (but not any Non-Recourse Party) under and to the extent expressly provided in this Guarantee (subject to any limitations expressly provided herein). Recourse against Guarantor under and pursuant to the terms of this Guarantee shall be the sole and exclusive remedy of the Company and all of its Affiliates against Guarantor and the Non-Recourse Parties in respect of any liabilities or obligations arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby, including by piercing of the corporate veil or by a claim by or on behalf of Parent or Merger Subsidiary. The Company hereby covenants

and agrees that it shall not institute, and it shall cause its Affiliates not to institute, any proceeding or bring any other claim arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby, against Guarantor or any Non-Recourse Party except for claims against Guarantor under this Guarantee or Obligor under the Merger Agreement. Nothing set forth in this Guarantee shall confer or give or shall be construed to confer or give to any Person other than the Company (including any Person acting in a representative capacity) any rights or remedies against any Person including Guarantor, except as expressly set forth herein.
