obligations under this Guaranty that an Obligation is not due under the terms of the Definitive
Agreement or has been performed pursuant to the terms thereof, each Guarantor agrees that the
obligation of such Guarantor hereunder shall not be released or discharged, in whole or in part, or

Guaranty other than as expressly set forth herein. All sums payable by the Guarantors hereunder
shall be made in immediately available funds. The Company acknowledges that, subject to Section&nbsp;4
hereof, payment by the Guarantors of the amounts contemplated hereby shall constitute satisfaction

hereof, upon payment of the Obligations owing to the Company, each Guarantor shall be subrogated to
the rights of the Company against the Purchaser in respect of such payment. However, no Guarantor
may exercise any right of subrogation as to the Purchaser until the Obligations have been satisfied

the Obligations have been satisfied in full. If any amount shall be paid to the Guarantor in
violation of the immediately preceding sentence at any time prior to the payment in full in cash of
the Obligations, such amount shall be received and held for the benefit of the Company, shall be
segregated from other property and funds of the Guarantor and shall forthwith be paid or delivered
