12.1The Guarantees. To induce the Noteholder to provide the credits described herein and in consideration of benefits expected to accrue to the Borrower by reason of the Commitments and the Advances and for other good and valuable consideration, receipt of which is hereby acknowledged, each Borrower and each Subsidiary of the Borrowers party hereto (including any Subsidiary executing an Additional Guarantor Supplement substantially in the form attached hereto as Exhibit B or such other form reasonably acceptable to the Noteholder and the Borrower (herein, an “Additional Guarantor Supplement”)), hereby unconditionally and irrevocably guarantees jointly and severally to the Noteholder, the due and punctual payment of all present and future Obligations, including, but not limited

to, the due and punctual payment of principal of and interest on the Advances and the due and punctual payment of all other Obligations now or hereafter owed by the Borrower under this Note, as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, according to the terms hereof and thereof (including all interest, costs, fees, and charges reimbursable hereunder after the entry of an order for relief against the Borrower or such other obligor in a case under the United States Bankruptcy Code or any similar proceeding, whether or not such interest, costs, fees and charges would be an allowed claim against the Borrower or any such obligor in any such proceeding). In case of failure by the Borrower or other obligor punctually to pay any Obligations guaranteed hereby, each Guarantor hereby unconditionally, jointly and severally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, and as if such payment were made by the Borrower or such obligor.

12.2Guarantee Unconditional. The obligations of each Guarantor under this Section 12 shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by:

(a)any extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of the Borrower or other obligor or of any other guarantor under this Note or by operation of law or otherwise;

(b)any modification or amendment of or supplement to this Note;

(c)any change in the corporate existence, structure, or ownership of, or any proceeding under any Debtor Relief Law affecting, the Borrower or other obligor, any other guarantor, or any of their respective assets, or any resulting release or discharge of any obligation of the Borrower or other obligor or of any other guarantor contained in this Note;

(d)the existence of any claim, set-off, or other rights which the Borrower or other obligor or any other guarantor may have at any time against the Noteholder or any other Person, whether or not arising in connection herewith;

(e)any failure to assert, or any assertion of, any claim or demand or any exercise of, or failure to exercise, any rights or remedies against the Borrower or other obligor, any other guarantor, or any other Person or property;

(f)any application of any sums by rights of set-off, counterclaim or similar rights to any obligation of any Borrower or other obligor, regardless of what obligations of the Borrower or other obligor remain unpaid, including the Obligations ;

(g)any invalidity or unenforceability relating to or against the Borrower or other obligor or any other guarantor for any reason of this Note or any provision of applicable law or regulation purporting to prohibit the payment by the Borrower or other obligor or any other guarantor of the principal of or interest on any Advance or any other amount payable under this Note; or

(h)any other act or omission to act or delay of any kind by the Noteholder or any other Person or any other circumstance whatsoever that might, but for the provisions of this clause (h), constitute a legal or equitable discharge of the obligations of any Guarantor under this Section 12.

12.3Discharge Only upon Payment in Full in Cash; Reinstatement in Certain Circumstances. Each Guarantor’s obligations under this Section 12 shall remain in full force and effect until the Commitments are terminated and the principal of and interest on the Advances and all other Obligations payable by the Borrower and the Guarantors under this Note (other than any contingent or indemnification obligations not then due) shall have been paid in full in cash. If at any time any payment of the principal of or interest on any Advance or any other amount payable by the Borrower or other obligor or any Guarantor under this Note is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of the Borrower or other obligor or of any guarantor, or

otherwise, each Guarantor’s obligations under this Section 12 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

12.4Subrogation. Each Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the Obligations (other than any contingent or indemnification obligations not then due) shall have been paid in full or subsequent to the termination of all the Commitments. If any amount shall be paid to a Guarantor on account of such subrogation rights at any time prior to the later of (a) the payment in full of the Obligation and all other amounts payable by the Borrower hereunder (other than any contingent or indemnification obligations not then due) and (b) the termination of the Commitments, such amount shall be held in trust for the benefit of the Noteholder and shall forthwith be paid to the Noteholder or be credited and applied upon the Obligations, whether matured or unmatured, in accordance with the terms of this Note.

12.5Subordination. Each Guarantor hereby subordinates the payment of all indebtedness, obligations, and liabilities of the Borrower or any other Guarantor owing to such Guarantor, whether now existing or hereafter arising, to the payment in full in cash of all Obligations (other than any contingent obligations not due and owing). During the existence of any Event of Default, subject to Section 12.4 above, any such indebtedness, obligation, or liability of the Borrower or any other Guarantor owing to such Guarantor shall be enforced and performance received by such Guarantor as trustee for the benefit of the holders of the Obligations and the proceeds thereof shall be paid over to the Noteholder for application to the Obligations (whether or not then due), but without reducing or affecting in any manner the liability of such Guarantor under this Section 12.

12.6Waivers. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice not provided for herein, as well as any requirement that at any time any action be taken by the Noteholder or any other Person against the Borrower or other obligor, another guarantor, or any other Person.

12.7Limit on Recovery. Notwithstanding any other provision hereof, the right of recovery against each Guarantor under this Section 12 shall not exceed $1.00 less than the lowest amount which would render such Guarantor’s obligations under this Section 12 void or avoidable under applicable law, including fraudulent conveyance law.

12.8Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Borrower or other obligor under this Note is stayed upon the insolvency, bankruptcy or reorganization of the Borrower or such obligor, all such amounts otherwise subject to acceleration under the terms of this Note shall nonetheless be payable by the Guarantors hereunder forthwith on demand by the Noteholder.

12.9Benefit to Guarantors. The Borrower and the Guarantors are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of the Borrowers has a direct impact on the success of each Guarantor. Each Guarantor will derive substantial direct and indirect benefit from the extensions of credit hereunder.

12.10Guarantor Covenants. Each Guarantor shall take such action as the Borrower is required by this Agreement to cause such Guarantor to take, and shall refrain from taking such action as the Borrower is required by this Agreement to prohibit such Guarantor from taking.

IN WITNESS WHEREOF, the Borrower has executed this Note as of the date first written above.
