This Guaranty Agreement may not be revoked by Guarantor and shall continue to be effective with respect to debt under the Liabilities arising or created after any attempted revocation by Guarantor and shall remain in full force and effect until the Liabilities are paid in full and the Revolving Credit Commitments are terminated, notwithstanding that from time to time prior thereto no Liabilities may be outstanding.

This Guaranty Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the Liabilities is rescinded or must otherwise be returned by any of the Banks upon the insolvency, bankruptcy or reorganization of Company or otherwise, all as though such payment had not been made.

Guarantor authorizes the Agent, without notice or demand and without affecting Guarantor's liability hereunder, to take and hold security for the payment of this Guaranty Agreement and/or the Liabilities, and exchange, enforce, waive and release any such security; and to apply such security and direct the order or manner of sale thereof as the Agent in its discretion may determine; and to obtain a guaranty of the Liabilities from any one or more Persons and at any time or times to enforce, waive, rearrange, modify, limit or release any of such other Persons from their obligations under such guaranties.

Whether and when to exercise any of the remedies of the Banks under any of the Loan Documents shall be in the sole and absolute discretion of the Agent, and no delay by the Agent in enforcing any remedy, including delay in conducting a foreclosure sale, shall be a defense to the Guarantor's liability under this Guaranty Agreement.

Until the Liabilities have been paid in full, the Guarantor waives all rights of subrogation or reimbursement against the Company, whether arising by contract or operation of law (including, without limitation, any such right arising under any federal or state bankruptcy or insolvency laws) and waives any right to enforce any remedy which the Banks now have or may hereafter have against the Company, and waives any benefit or any right to participate in any security now or hereafter held by the Agent or any Bank.
