NOW, THEREFORE, in order to induce Hexagon to make the Loan, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby jointly and severally covenants and agrees as follows: 1. Each Guarantor irrevocably, unconditionally, jointly and severally fully guarantees the due, prompt and complete performance of each and every one of the following obligations: (a) the payment and performance by Maker of each and every obligation of Maker under the Note and the other Loan Documents to which it is a party; and (b) the due, prompt and complete payment of all costs and expenses (including, without limitation, reasonable attorneys' fees) incurred by Hexagon in collection or enforcement of this Guaranty Agreement against the Guarantors (the obligations described in this Paragraph 1 are hereinafter collectively referred to as the "Indebtedness"). 2. Each Guarantor hereby grants to Hexagon, in the absolute discretion of Hexagon, and without notice to any Guarantor, the power and authority to deal in any lawful manner with the Indebtedness and the other obligations guaranteed hereby, and without limiting the generality of the foregoing, the further power and authority, from time to time: (a) to renew, compromise, extend, accelerate or otherwise change the time or place of payment of or to otherwise change the terms of the Indebtedness; (b) to modify or to waive any of the terms of the obligations guaranteed hereby; (c) to take and hold security for the payment of the Indebtedness and/or performance of the other obligations guaranteed hereby and to impair, exhaust, exchange, enforce, waive or release any such security; (d) to direct the order or manner of sale of any such security as Hexagon, in its discretion, may determine; (e) to grant any indulgence, forbearance or waiver with respect to the Indebtedness or any of the other obligations guaranteed hereby; and (f) to release or waive rights against any one or more Guarantors without releasing or waiving any rights against any other Guarantor.

The Guarantors agree that if any of the Indebtedness is not fully and timely paid or performed according to the tenor thereof, whether by acceleration or otherwise, the Guarantors shall immediately upon receipt of written demand therefor from Hexagon pay all of the Indebtedness hereby guaranteed in like manner as if the Indebtedness constituted the direct and primary obligation of the Guarantors. The Guarantors shall not have any right of subrogation as a result of any payment hereunder or any other payment made by the Guarantors or a Guarantor on account of the Indebtedness, and each Guarantor hereby waives, releases and relinquishes any claim based on any right of subrogation, any claim for unjust enrichment or any other theory that would entitle a Guarantor to a claim against Maker based on any payment made hereunder or otherwise on account of the Indebtedness until Hexagon is paid in full. 4. This Guaranty Agreement and the obligations of the Guarantors hereunder shall be continuing and irrevocable until the Indebtedness has been satisfied in full.

The provisions of the foregoing sentence shall survive termination of this Guaranty Agreement, and shall remain a valid and binding obligation of each Guarantor until satisfied. 5. Each Guarantor hereby waives notice of acceptance of this Guaranty Agreement by Hexagon and this Guaranty Agreement shall immediately be binding upon each Guarantor. Any Guarantor who executes this Guaranty Agreement shall be fully bound hereby regardless of whether or not any other Guarantor subsequently executes this Guaranty Agreement. 6.
