WHEREAS, the execution and delivery by Guarantor of this Unconditional and Continuing Guaranty (the “Guaranty”) is a condition precedent to the obligation of Bank to extend credit to Borrower; and

WHEREAS, Guarantor will derive substantial benefits from the credit extended to Borrower.

NOW, THEREFORE, in contemplation of the premises and of other good and valuable consideration, the receipt of which is hereby acknowledged, Guarantor hereby represents and agrees as follows:

1.

Guaranty.

Guarantor hereby absolutely, irrevocably and unconditionally guarantees to Bank the punctual and full payment when due, whether at the stated date or dates for such payment, by acceleration or otherwise, of all indebtedness, liabilities and obligations of Borrower to Bank of every name and nature whatsoever, whether absolute or contingent, now existing or hereafter arising, secured or unsecured, created directly or acquired indirectly by assignment or otherwise and whether on open account, or evidenced by a promissory note, cheek, draft, continuing credit agreement, continuing agreement for letters of credit, continuing agreement for bankers’ acceptances or any other instrument or document, and whether created as maker, debtor, surety, endorser, guarantor, pledgor, account party or otherwise, and including, without limitation, all principal, interest, premiums, fees, cost and expense reimbursements, letter of credit reimbursement obligations, acceptance fees and commissions and all other obligations assumed under the documentation of such indebtedness, liabilities and obligations, all of which are referred to herein as the “Obligations.”

2.

Payment By Guarantor.

 In the event of a default by Borrower under any of the Obligations and/or the failure of a Borrower punctually to pay any of the Obligations when due, Guarantor hereby agrees to make such payment punctually when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise. Each such payment shall be made at the main office of Bank (or at such other office as Bank shall specify by written notice to Guarantor), in immediately available funds.

While this Guaranty is in effect, all accounts, deposits and property of Guarantor on deposit with or otherwise in the hands of Bank arc hereby and shall continue to be and stand pledged and impressed with a lien as collateral security for all Obligations, and Bank shall have the same right of set-off with respect to deposits and credits in favor of Guarantor as it has with respect to deposits and credits of Borrower.

3.

Obligations of Guarantor Unconditional.

 Guarantor hereby agrees that:

3.1.

Guarantor’s liability hereunder is unconditional, irrespective of:

3.1.1.

the legality, validity or enforceability of the Obligations;

3.1.2.

3.1.3.

the absence of any action or effort by Bank to either resort to, enforce or exhaust its remedies under or against the Obligations and/or the Collateral Security;

3.1.4.

the waiver or consent by Bank with respect to any provision in the documentation of the Obligations or the Collateral Security;

3.1.5.

the recovery of any judgment against Borrower or any action to enforce such judgment or any other circumstance which might, absent the unconditional nature of this Guaranty, constitute a legal or equitable discharge or defense of a Guarantor.

3.2.

Bank may at any time, or from time to time, in Bank’s sole discretion:

3.2.1.

change, alter, renew, continue, extend and/or accelerate the time of payment of, all or any of the Obligations, or any part or parts thereof or any renewal or renewals thereof;

3.2.2.

replace any existing Obligation and the documentation therefor with an amended and restated Obligation and the documentation therefor;

3.2.3.

3.2.4.

sell and/or purchase any or all of the Collateral at public or private sale, or at any broker’s board, and after deducting all costs and expenses of every kind for collection, sale and/or delivery, apply the proceeds of any such sale or sales against any of the Obligations;

3.2.5.

settle or compromise any or all of the Obligations with Borrower, and/or any other person or persons liable thereon, and/or subordinate the payment of same or any part thereof to the payment of any other debts or claims which may at any time be due or owing to Bank and/or other person, all in such manner and upon such terms as Bank may see fit and without notice to or the consent from Guarantor, who hereby agrees to be and remain bound upon this Guaranty, irrespective of the effect upon the existence or status of the Obligations or the Collateral Security and notwithstanding any such change, alteration, renewal, continuance, extension, acceleration, sale, exchange, release, compromise, surrender, application, settlement, subordination or other action hereinabove mentioned.

3.3.

The liability of Guarantor will not be discharged except by complete and final performance of the Obligations.

3.4.

The liability of Guarantor under this Guaranty shall be reinstated with respect to any amount paid to Bank by Borrower which is hereafter required to be returned to Borrower or any trustee, receiver or other representative of or for such Borrower, upon or by reason of the bankruptcy, insolvency, reorganization, or dissolution of such Borrower, or for any other reason, all as though such amount had never been paid by Borrower.

3.5.

This is a guaranty of payment and not merely of collection.

4.

No Subrogation.

 No payment by Guarantor pursuant to any provision of this Guaranty or other satisfaction of Guarantor’s liabilities hereunder shall entitle Guarantor, by subrogation to the rights of Bank or otherwise, to any payment from Borrower, from the proceeds of the property of Borrower or from any Collateral Security, except after satisfaction in full of all of the Obligations and the expiration of any and all applicable preference periods during which the payments credited to the satisfaction of the Obligations may be required to be returned to the payor thereof or such person’s trustee, receiver or other representative.
