3. Surety’s determination in its sole and absolute discretion of the foregoing shall be final and conclusive upon the Undersigned.

4. An itemized statement of loss and expense incurred by Surety, sworn to by an officer of Surety, shall be prima facie evidence of the fact and extent of the liability of Undersigned to Surety in any claim or suit by Surety against Undersigned.

Agree that all monies earned by Contractor under any Contract are trust funds, whether in the possession of Contractor or otherwise, for the benefit of, and for payment of Contractor’s obligations for, labor, material, and supplies furnished to Contractor in performance of such Contract for which Surety would be liable under any Bond on such Contract, and the performance of Contractor’s or Surety’s obligations to any Obligee on such Contract;

5. Agree that this agreement may at any time be completed and filed by Surety in such a manner that it will qualify as a financing statement under the applicable provisions of any statute of any state which has adopted The Uniform Commercial Code, and that Surety may add such schedules to this agreement, describing specific items of security covered hereunder as shall be necessary under such statutes.

GENERAL PROVISIONS:

1. Assent by Surety to changes in any Contract or Bond or refusal to assent shall not release or affect the obligations of Undersigned to Surety even though any such assent by the Surety does or might increase the liability of the Undersigned.

2. Surety has the right to decline to execute, provide or procure any bond requested by Contractor. If Surety does execute, provide or procure the execution of a bid bond or proposal bond, or agrees or consents to provide such contract of suretyship, Surety retains the right to decline to execute the final bond (including, but not limited to, performance, payment or maintenance bonds) that may be required in connection with any award that may be made under the bid proposal or tender to which the bid proposal bond or agreement or consent to provide such contract of suretyship is given.

3. Surety shall have every right, defense or remedy which a personal surety without compensation would have, including the right of exoneration and the right of subrogation. The security interest, trust, and other rights granted herein will not be deemed a waiver of Surety’s equitable subrogation rights or other rights, said security in rights being in addition to the rights of exoneration, subrogation, and other rights to which Surety is entitled to under law or in equity.

4. Until Surety shall have been furnished with competent evidence of its discharge, without loss from any Bonds, Surety shall have the right to free access at reasonable times to the books, records and accounts of each of the Undersigned for the purpose of examining, copying or reproducing them. Each one of the Undersigned hereby authorizes any depositories in which funds of any of the Undersigned may be deposited to furnish to Surety the amount of such deposits as of any date requested, and any legal entity doing business with the undersigned is authorized to furnish any information requested by Surety concerning any transaction. Surety may furnish in confidence copies of any information, which it now has or may hereafter obtain concerning each of the Undersigned, to other persons or companies for the purpose of procuring co-suretyship or reinsurance or of advising interested persons or companies.

5. The Undersigned will, on request of Surety, procure the discharge of Surety from any Bond and all liability by reason thereof. If such discharge is unattainable, the Undersigned will, if requested by Surety, either deposit collateral with Surety, acceptable to Surety, sufficient to cover all exposure under such bond or bonds, or make provisions acceptable to Surety for the funding of the bonded obligation(s).

6. Undersigned warrant that each of them is specifically and beneficially interested in the obtaining of each Bond.

7. In case the execution hereof by any of the Undersigned may be defective or invalid for any reason, such defect or invalidity shall not in any manner affect the validity of this obligation or the liability hereunder of any other of the Undersigned. Invalidity of any provision of this agreement by reason of the laws of any state or for any other reason shall not render the other provisions hereof invalid.

8. Execution by Contractor or any of the Undersigned of any application for any Bond or of any other agreement of indemnity in behalf of Contractor, or the taking of indemnity of any other person by Surety with respect to any Bond of Contractor, shall in no way be deemed to waive, diminish or abrogate any rights of Surety under this agreement.

9. The Undersigned waive and subordinate all rights of indemnity, subrogation and contribution each against the other until all obligations to the Surety under this agreement, at law or in equity, have been satisfied in full.

10. The rights and remedies afforded to the Surety by the terms of this agreement and the terms themselves may not be waived or modified orally and no written change or modification shall be effective until signed by an employee of the Surety,

11. This agreement is to be liberally construed so as to protect, exonerate and indemnify the Surety.

12. All parties agree that any microfilmed, scanned or electronically digitized copy of this document made by Surety as part of its record storage and retention program shall be as effective as the original for all purposes.

13. The Undersigned has relied upon its own due diligence in making its own independent appraisal of Contractor and its business and financial condition, will continue to be responsible for making its own independent appraisal of such matters, and has not relied upon and will not hereafter rely upon Surety for information. Surety has no duty to inform any of the undersigned Indemnitors of the financial condition or other affairs related to Contractor.

14. The Undersigned shall remain responsible to Surety under this Agreement regardless of any changes in the relationship of the Undersigned with Contractor.

TERMINATION: This agreement is a continuing obligation of the Undersigned unless terminated as provided in this paragraph. An Undersigned desiring to terminate liability as to future Bonds of Contractor must:

2. State in such notice the effective date (not less than thirty days after the receipt of notice by Surety) of termination of such Undersigned's liability for future Bonds.

After the effective date of termination, the Undersigned giving notice shall be liable hereunder for:

1. Bonds executed or authorized prior to such date, and renewals and extensions thereof;

2. Bonds executed pursuant to a bid or proposal bond executed or authorized prior to such date, and renewals and extensions thereof.
