(the “Stock Purchase Agreement”) and (b) consummation of the Transactions (as defined in the Stock Purchase Agreement). No course of dealing on the part of Bank or its officers shall operate as a consent by Bank, and Bank’s failure at any time to require strict performance by Borrower of any provision shall not affect any right of Bank thereafter to demand strict compliance and performance. Any further consent must be in writing signed by an officer of Bank.

5. Release.

(a) New Guarantor and Loan Parties acknowledge that Bank would not enter into this First Amendment and Joinder, without New Guarantor and Loan Parties’ assurance hereunder. Except for the obligations arising hereafter under the Loan Agreement, Loan Parties hereby absolutely discharge and release Bank, any person or entity that has obtained any interest from Bank under the Loan Agreement and each of Bank’s and such entity’s

2

former and present partners, stockholders, officers, directors, employees, successors, assignees, agents, and attorneys from any known or unknown claims which Loan Parties now have against Bank of any nature, including any claims that Loan Parties, their successors, counsel, and advisors may in the future discover they would have now had if they had known facts not now known to them, whether founded in contract, in tort, or pursuant to any other theory of liability, including but not limited to any claims arising out of or related to the Loan Agreement or the transactions contemplated thereby.

(b) The provisions, waivers, and releases set forth in this Section are binding upon New Guarantor and Loan Parties’ shareholders, members, agents, employees, assigns, and successors in interest. The provisions, waivers, and releases of this Section shall inure to the benefit of Bank and its agents, employees, officers, directors, assigns, and successors in interest.

(c) New Guarantor and Loan Parties warrant and represent that New Guarantor and Loan Parties are the sole and lawful owners of all right, title and interest in and to all of the claims released hereby, and New Guarantor and Loan Parties have not heretofore voluntarily, by operation of law or otherwise, assigned or transferred or purported to assign or transfer to any person any such claim or any portion thereof. New Guarantor and Loan Parties shall indemnify and hold harmless Bank from and against any claim, demand, damage, debt, liability (including payment of attorneys’ fees and costs actually incurred whether or not litigation is commenced) based on or arising out of any assignment or transfer.

(d) The provisions of this Section shall survive payment in full of the Obligations, full performance of all of the terms of this First Amendment and Joinder and the Loan Agreement, and/or Bank’s actions to exercise any remedy available under the Loan Agreement or otherwise.

6. No Course of Dealing; Strict Performance. No course of dealing on the part of Bank or its officers, nor any failure or delay in the exercise of any right by Bank, shall operate as a waiver thereof, and any single or partial exercise of any such right shall not preclude any later exercise of any such right. Bank’s failure at any time to require strict performance by New Guarantor and Loan Parties of any provision shall not affect any right of Bank thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Bank.

7. Ratification; No Amendment. The Loan Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its respective terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and performance of this First Amendment and Joinder shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Bank under the Loan Agreement, as in effect prior to the date hereof.

8. Representations and Warranties; No Event of Default. New Guarantor and Loan Parties hereby represent and warrant to Bank, which representations and warranties shall survive the execution and delivery hereof, that: (a) this First Amendment and Joinder is the legally valid and binding obligation of New Guarantor, enforceable against New Guarantor and Loan Parties in accordance with its terms, (b) except as otherwise set forth below, each of the representations and warranties contained in the Loan Agreement, as well as all other representations and warranties contained in the other Loan Documents, are true and correct in all material respects (without duplication of any materiality qualifier in the text of such representation or warranty) to the extent required under the Loan Agreement, and (c) that no Event of Default has occurred and is continuing.

9. Counterparts; Facsimile and other Electronic Transmission. This First Amendment and Joinder may be executed in any number of counterparts and by the different parties hereto on separate counterparts, and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute but one and the same First Amendment and Joinder. Receipt of an executed signature page to this First Amendment and Joinder by facsimile or other electronic transmission shall constitute for all purposes effective delivery thereof. Electronic records of this executed First Amendment and Joinder maintained by Bank shall be deemed to be originals.
