5. Limited Waiver. Subject to and on the terms and conditions set forth herein, Agent and the Lenders, hereby waive the Existing Defaults; provided however, that such waiver: (a) applies only to the instance specified above and for the times stated, (b) is not a waiver of any subsequent breach of the same provision of the Loan Agreement or any other Loan Document, and (c) shall not extend or apply to, and is not a waiver of any breach of, any other Default of Event of Default. Nothing herein constitutes a waiver, amendment or forbearance of Borrower’s obligation to pay the Obligations, as and when due. This waiver is not a continuing waiver with respect to any Event of Default or any obligation that Borrower may have under the Loan Agreement or the other Loan Documents after the date hereof. Except as expressly set forth above, Agent and Lenders do not waive any failure by Borrower to perform any obligation under the Loan Agreement or any other Loan Document. Agent and each Lender reserves all of their respective rights, powers and remedies available to them under the Loan Documents and applicable law, including the right to cease making advances to Borrower and to accelerate any or all of Borrower’s indebtedness if any subsequent breach of the same provisions or any other provision of the Loan Agreement or any other Loan Document should occur. Neither Agent nor any Lender is obligated to grant this or any other waiver, consent or loan modification.

6. Ratification and Confirmation of Loan Documents. Except as expressly set forth in Section 3 hereof, the execution, delivery, and performance of this Amendment shall not alter, modify, amend, or in any way affect any of the terms, conditions, obligations, covenants, or agreements contained in the Loan Agreement or any other Loan Document, and shall not operate as a waiver of any right, power, or remedy of Agent or any Lender under the Loan Agreement or any other Loan Document. The Loan Agreement, all promissory notes, guaranties, security agreements, and all other instruments, documents and agreements entered into in connection with the Loan Agreement and each other Loan Document shall be and remain in full force and effect in accordance with their respective terms and hereby are ratified and confirmed by Borrower in all respects.

7. No Other Waivers. This Amendment: (a) in no way shall be deemed to imply a willingness on the part of Agent or any Lender to grant any similar or other future waivers or to agree to any future consents, amendments or modifications to any of the terms and conditions of the Loan Agreement or the other Loan Documents; and (b) shall not in any way, prejudice, limit, impair or otherwise affect any rights or remedies of Agent or any Lender under the Loan Agreement or any of the other Loan Documents, including, without limitation, Agent’s or any Lender’s right to demand strict performance of Borrower’s liabilities and obligations to Agent and the Lenders and the Obligations under the Loan Documents at all times. Borrower acknowledges and agrees that Agent and each Lender is relying upon Borrower’s representations, warranties and agreements, as set forth herein and in the other Loan Documents in entering into this Amendment. Nothing in this Amendment shall constitute a satisfaction of Borrower’s Obligations.

8. Miscellaneous. Borrower acknowledges and agrees that the representations and warranties set forth herein are material inducements to Agent and the Lenders to deliver this Amendment. This Amendment shall be binding upon and inure to the benefit of and be enforceable by the parties

hereto, and their respective permitted successors and assigns. This Amendment and the Loan Agreement shall be read together as one document. No course of dealing on the part of Agent, the Lenders or any of their respective officers, nor any failure or delay in the exercise of any right by Agent or the Lenders, 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. The failure at any time to require strict performance by Borrower of any provision of the Loan Documents shall not affect any right of Agent or the Lenders thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Agent and/or the Lenders, as applicable. No other Person shall be entitled to claim any right or benefit hereunder, including, without limitation, the status of a third party beneficiary hereunder. This Amendment shall be governed by and construed in accordance with the laws of the State of California without reference to conflicts of law rules. If any provision of this Amendment or any of the other Loan Documents shall be determined by a court of competent jurisdiction to be invalid, illegal or unenforceable, that portion shall be deemed severed herefrom or therefrom, as applicable, and the remaining parts shall remain in full force as though the invalid, illegal or unenforceable portion had never been a part hereof or thereof, as applicable. This Amendment may be executed in any number of counterparts, including by electronic or facsimile transmission, each of which when so delivered shall be deemed an original, but all such counterparts taken together shall constitute but one and the same instrument.
