GUARANTY

Section 2.1 Guaranty

Subject to Section 2.7 hereof and solely to the extent demand for payment is made by Beneficiary under Section 2.5 hereof, Guarantor hereby irrevocably, absolutely, fully and unconditionally guarantees to Beneficiary and its permitted successors and assigns the prompt and complete payment when and as due of Obligor’s unfulfilled payment obligations under Section 5.2 of the MPA in accordance with, and subject to, the limitations and other provisions set forth in the MPA (the “Guaranteed Obligations”).

1

Section 2.2 No Release or Discharge

Subject to the limitations in Section 2.1 hereof, this Guaranty is a primary obligation of Guarantor and shall be an irrevocable, unconditional, and absolute guaranty, irrespective of:

(a) any modification, amplification, amendment, supplement, renewal or waiver of the MPA or any of the terms or conditions of the MPA;

(b) any postponement or extension of the date on which any payment must be made pursuant to the MPA or postponement or extension of the date on which any act must be performed by Obligor thereunder;

(c) any change in the organization or structure of Beneficiary or any of its Affiliates; and

(d) any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a guarantor, including any termination of or change in corporate existence, structure or ownership of Obligor or Guarantor, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting Obligor or its assets;

all without notice to or assent by Guarantor, who shall remain bound by this Guaranty, which shall remain in full force and effect until all of the Guaranteed Obligations have been indefeasibly paid, notwithstanding any such event or circumstance or any such act by Beneficiary.

Section 2.3 Waiver of Rights

Subject to the limitations expressly set forth in this Guaranty, Guarantor understands and agrees that the guaranty contained in Section 2.1 hereof shall continue in effective, irrespective of any circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor. Guarantor hereby expressly waives diligence, presentment, protest and all notices whatsoever (other than the notice contemplated by Section 2.5 hereof) and any requirement that Beneficiary exhaust any right, power or remedy or proceed against Obligor under the MPA or any other agreement or instrument referred to herein or therein. Without limiting Guarantor’s own defenses and rights hereunder, Guarantor reserves to itself all rights, setoffs, counterclaims and other defenses that Obligor may have to payment of all or any portion of the Guaranteed Obligations except any legal or equitable discharge or defense arising from bankruptcy, insolvency, dissolution or liquidation of Obligor and other defenses expressly waived in this Guaranty.

Section 2.4 Postponement of Subrogation

Guarantor shall be subrogated to all rights of Beneficiary against Obligor in respect of any amounts paid by such Guarantor pursuant to this Guaranty; provided, however, that Guarantor hereby postpones all rights of subrogation, reimbursement, indemnity and recourse (including any statutory rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C. § 509, or otherwise) until such time as the Guaranteed Obligations are paid or otherwise satisfied in full. If (a) Guarantor makes payment to Beneficiary of all or any part of the Guaranteed Obligations

2

and (b) all of the then outstanding Guaranteed Obligations shall have been paid or otherwise satisfied in full, Beneficiary shall, at Guarantor’s request, execute and deliver to Guarantor documents to evidence the transfer by subrogation to Guarantor of any interest in the Guaranteed Obligations resulting from such payment by Guarantor.

Section 2.5 Notice of Default

Beneficiary will provide written notice in compliance with Section 4.1 hereof to Guarantor if Obligor defaults in any of its obligations under the MPA and such default may trigger the obligations of Guarantor under this Guaranty describing in reasonable detail the default thereunder and the payment requested, or the amount of any claims made, by Beneficiary under this Guaranty with respect to such default.

Section 2.6 Guaranty of Payment and Not Collection

This is a guaranty of payment when and as due and not merely of collection.

Section 2.7 Reinstatement

If any of the Guaranteed Obligations have been paid by Guarantor but such payment is forfeited, reclaimed or otherwise repaid pursuant to bankruptcy, insolvency or similar Laws, then claims for such amount as was so forfeited, reclaimed or otherwise repaid shall be revived and continue as if such payment or proceeds had not been received by Beneficiary from Guarantor under this Guaranty.
