8.5. No Implied Waiver; Cumulative Remedies.

This Agreement and the other Loan Documents supersede all prior and contemporaneous understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein and therein.

Each Credit Party hereby agrees that if any Obligation of such Credit Party shall be due and payable (by acceleration or otherwise), and such Credit Party shall fail to pay the same beyond any cure period with respect thereto, the Lender shall have the right, without notice to such Credit Party, to set-off against and to appropriate and apply to such Obligation any indebtedness, liability or obligation of any nature owing to such Credit Party by the Lender, including all deposits (whether time or demand, general or special, provisionally credited or finally credited, whether or not evidenced by a certificate of deposit) now or hereafter maintained by such Credit Party with the Lender, in each case to the maximum extent permitted by Law. Such right shall be absolute and unconditional in all circumstances and, without limitation, shall exist whether or not the Lender or any other Person shall have given notice or made any demand to such Credit Party or any other Person, whether such indebtedness, obligation or liability owed to such Credit Party is contingent, absolute, matured or unmatured (it being agreed that the Lender may deem such indebtedness, obligation or liability to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty or any other security, right or remedy available to the Lender or any other Person. The Lender agrees promptly to notify such Credit Party after any such set-off and application made by the Lender; provided, however, that the failure to give such notice shall not effect the validity of set-off application. Each Credit Party hereby agrees that any branch, subsidiary or affiliate of the Lender shall have the same rights of set-off as the Lender as provided in this Section 8.13 (regardless of whether such branch, subsidiary or affiliate would otherwise be deemed in privity with or a direct creditor of such Credit Party). The rights provided by this Section 8.13 are in addition to all other rights of set-off and banker’s lien and all other rights and remedies which the Lender (or any such branch, subsidiary or affiliate) may otherwise have under this Agreement, any other Loan Document, at law or in equity, or otherwise, and nothing in this Agreement or any other Loan Document shall be deemed a waiver or prohibition of or restriction on the rights of set-off or banker’s lien of any such Person.

8.14. Successors and Assigns; Assignments.

(a) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Credit Parties, the Lender, all future holders of the Notes, and their respective successors and assigns, except that the Credit Parties may not assign or transfer any of their rights hereunder or interests herein without the prior written consent of all the Lender, and any purported assignment without such consent shall be void.

(b) Assignments. The Lender may at any time assign all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including all or any portion of its Commitments and Loans owing to it and any Note held by it) to any Person. Upon such assignment, the purchasing Lender shall be a party hereto and shall have the rights and obligations of the Lender hereunder, and the Lender shall be released from its obligations under this Agreement to the extent so transferred (and, in the case of an assignment covering all or the remaining portion of the Lender’s rights and obligations under this Agreement, the Lender shall cease to be a party to this Agreement).

(c) Financial and Other Information. The Credit Parties authorize the Lender to disclose to any transferee and any prospective transferee any and all financial and other information in its possession concerning the Credit Parties and affiliates which has been or may be delivered to it by or on behalf of the Credit Parties in connection with this Agreement or any other Loan Document or its credit evaluation of the Credit Parties.

8.15. Materiality.

Unless the context clearly indicates to the contrary, determinations regarding the materiality of any act, event, condition or circumstance shall be in the reasonable judgment of the Lender.

8.16. Governing Law; Arbitration: Waiver of Jury Trial; Limitation of Liability.

(a) Governing Law.

THIS AGREEMENT AND ALL OTHER LOAN DOCUMENTS (EXCEPT TO THE EXTENT, IF ANY, OTHERWISE EXPRESSLY STATED IN SUCH OTHER LOAN DOCUMENTS) SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF VIRGINIA, WITHOUT REGARD TO CHOICE OF LAW PRINCIPLES.

(b) Arbitration; Jury Trial Waiver.

(i) THIS PARAGRAPH CONCERNS THE RESOLUTION OF ANY CONTROVERSIES OR CLAIMS BETWEEN ANY

CREDIT PARTY AND LENDER, WHETHER ARISING IN CONTRACT, TORT OR BY STATUTE, INCLUDING BUT NOT LIMITED TO CONTROVERSIES OR CLAIMS THAT ARISE OUT OF OR RELATE TO: (I) THIS AGREEMENT (INCLUDING ANY RENEWALS, EXTENSIONS OR MODIFICATIONS); OR (II) ANY DOCUMENT RELATED TO THIS AGREEMENT (COLLECTIVELY A “CLAIM”);

(ii) AT THE REQUEST OF ANY CREDIT PARTY OR LENDER, ANY CLAIM SHALL BE RESOLVED BY BINDING ARBITRATION IN ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (TITLE 9, U.S. CODE) (THE “ACT”). THE ACT WILL APPLY EVEN THOUGH THIS AGREEMENT PROVIDES THAT IT IS GOVERNED BY THE LAW OF A SPECIFIED STATE;

(iii) ARBITRATION PROCEEDINGS WILL BE DETERMINED IN ACCORDANCE WITH THE ACT, THE APPLICABLE RULES AND PROCEDURES FOR THE ARBITRATION OF DISPUTES OF JAMS OR ANY SUCCESSOR THEREOF (“JAMS”), AND THE TERMS OF THIS PARAGRAPH. IN THE EVENT OF ANY INCONSISTENCY, THE TERMS OF THIS PARAGRAPH SHALL CONTROL;

(iv) THE ARBITRATION SHALL BE ADMINISTERED BY JAMS AND CONDUCTED IN ANY U.S. STATE WHERE REAL OR TANGIBLE PERSONAL PROPERTY COLLATERAL FOR THIS CREDIT IS LOCATED OR IF THERE IS NO SUCH COLLATERAL, IN THE COMMONWEALTH OF VIRGINIA. ALL CLAIMS SHALL BE DETERMINED BY ONE ARBITRATOR; HOWEVER, IF CLAIMS EXCEED $5,000,000, UPON THE REQUEST OF ANY PARTY, THE CLAIMS SHALL BE DECIDED BY THREE ARBITRATORS. ALL ARBITRATION HEARINGS SHALL COMMENCE WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION AND CLOSE WITHIN 90 DAYS OF COMMENCEMENT AND THE AWARD OF THE ARBITRATOR(S) SHALL BE ISSUED WITHIN 30 DAYS OF THE CLOSE OF THE HEARING. HOWEVER, THE ARBITRATOR(S), UPON A SHOWING OF GOOD CAUSE, MAY EXTEND THE COMMENCEMENT OF THE HEARING FOR UP TO AN ADDITIONAL 60 DAYS.

(v) THE ARBITRATOR(S) WILL HAVE THE AUTHORITY TO DECIDE WHETHER ANY CLAIM IS BARRED BY THE STATUTE OF LIMITATIONS AND, IF SO, TO DISMISS THE ARBITRATION ON THAT BASIS. FOR PURPOSES OF THE APPLICATION OF THE STATUTE OF LIMITATIONS, THE SERVICE ON JAMS UNDER APPLICABLE JAMS RULES OF A NOTICE OF CLAIM IS THE EQUIVALENT OF THE FILING OF A LAWSUIT. ANY DISPUTE CONCERNING THIS ARBITRATION PROVISION OR WHETHER A CLAIM IS ARBITRABLE SHALL BE DETERMINED BY THE ARBITRATOR(S). THE ARBITRATOR(S) SHALL HAVE THE POWER TO AWARD LEGAL FEES PURSUANT TO THE TERMS OF THIS AGREEMENT;

(vi) THIS PARAGRAPH DOES NOT LIMIT THE RIGHT OF ANY CREDIT PARTY OR LENDER TO: (I) EXERCISE SELF-HELP REMEDIES, SUCH AS BUT NOT LIMITED TO, SETOFF; (II) INITIATE JUDICIAL OR NONJUDICIAL FORECLOSURE AGAINST ANY REAL OR PERSONAL PROPERTY COLLATERAL; (III) EXERCISE ANY JUDICIAL OR POWER OF SALE RIGHTS, OR (IV) ACT IN A COURT OF LAW TO OBTAIN AN INTERIM REMEDY, SUCH AS BUT NOT LIMITED TO, INJUNCTIVE RELIEF, WRIT OF POSSESSION OR APPOINTMENT OF A RECEIVER, OR ADDITIONAL OR SUPPLEMENTARY REMEDIES; AND

(vii) BY AGREEING TO BINDING ARBITRATION, THE PARTIES IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM. FURTHERMORE, WITHOUT INTENDING IN ANY WAY TO LIMIT THIS AGREEMENT TO ARBITRATE, TO THE EXTENT ANY CLAIM IS NOT ARBITRATED, THE PARTIES IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF SUCH CLAIM. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING INTO THIS AGREEMENT.

(c) Limitation of Liability.

TO THE FULLEST EXTENT PERMITTED BY LAW, NO CLAIM MAY BE MADE BY ANY CREDIT PARTY AGAINST THE LENDER OR ANY AFFILIATE, DIRECTOR, OFFICER, EMPLOYEE, ATTORNEY OR AGENT OF IT FOR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN RESPECT OF ANY

CLAIM ARISING FROM OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY STATEMENT, COURSE OF CONDUCT, ACT, OMISSION, OR EVENT OCCURRING IN CONNECTION HEREWITH OR THEREWITH (WHETHER FOR BREACH OF CONTRACT, TORT OR ANY OTHER THEORY OF LIABILITY). EACH CREDIT PARTY HEREBY WAIVES, RELEASES AND AGREES NOT TO ▇▇▇ UPON ANY CLAIM FOR ANY SUCH DAMAGES, WHETHER SUCH CLAIM PRESENTLY EXISTS OR ARISES HEREAFTER AND WHETHER OR NOT SUCH CLAIM IS KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.
