A. Acceleration. You may make all or any part of the amount owing by the terms of the Loan immediately due. If I am a debtor in a bankruptcy petition or in an application filed under section 5(a)(3) of the Securities Investor Protection Act, the Loan is automatically accelerated and immediately due and payable without notice or demand upon filing of the petition or application.

B. Sources. You may use any and all remedies you have under state or federal law or in any Loan Document.

C. Insurance Benefits. You may make a claim for any and all insurance benefits or refunds that may be available on my default.

D. Payments Made On My Behalf. Amounts advanced on my behalf will be immediately due and may be added to the balance owing under the terms of the Loan, and accrue interest at the highest post-maturity interest rate.

E. Termination. You may terminate my right to obtain advances and may refuse to make any further extensions of credit.

F. Set-Off. You may use the right of set-off. This means you may set-off any amount due and payable under the terms of the Loan against any right I have to receive money from you. My right to receive money from you includes any deposit or share account balance I have with you; any money owed to me on an item presented to you or in your possession for collection or exchange; and any repurchase agreement or other non-deposit obligation. “Any amount due and payable under the terms of the Loan” means the total amount to which you are entitled to demand payment under the terms of the Loan at the time you set-off.

Subject to any other written contract, if my right to receive money from you is also owned by someone who has not agreed to pay the Loan, your right of set-off will apply to my interest in the obligation and to any other amounts I could withdraw on my sole request or endorsement. Your right of set-off does not apply to an account or other obligation where my rights arise only in a representative capacity. It also does not apply to any Individual Retirement Account or other tax-deferred retirement account. You will not be liable for the dishonor of any check when the dishonor occurs because you set-off against any of my accounts. I agree to hold you harmless from any such claims arising as a result of your exercise of your right of set-off.

G. Waiver. Except as otherwise required by law, by choosing any one or more of these remedies you do not give up your right to use any other remedy. You do not waive a default if you choose not to use a remedy. By electing not to use any remedy, you do not waive your right to later consider the event a default and to use any remedies if the default continues or occurs again.

9. COLLECTION EXPENSES AND ATTORNEYS’ FEES. On or after Default, to the extent permitted by law, I agree to pay all expenses of collection, enforcement or protection of your rights and remedies under this Agreement or any other Loan Document. Expenses include (unless prohibited by law) reasonable attorneys’ fees, court costs, and other legal expenses. These expenses are due and payable immediately. If not paid immediately, these expenses will bear interest from the date of payment until paid in full at the highest interest rate in effect as provided for in the terms of this Loan. All fees and expenses will be secured by the Property I have granted to you, if any. In addition, to the extent permitted by the United States Bankruptcy Code, I agree to pay the reasonable attorneys’ fees incurred by you to protect your rights and interests in connection with any bankruptcy proceedings initiated by or against me.

10. APPLICABLE LAW. This Agreement is governed by the laws of Virginia, the United States of America, and to the extent required, by the laws of the jurisdiction where the Property is located

11. JOINT AND INDIVIDUAL LIABILITY AND SUCCESSORS. My obligation to pay the Loan is independent of the obligation of any other person who has also agreed to pay it. You may sue me alone, or anyone else who is obligated on the Loan, or any number of us together, to collect the Loan. Extending the Loan or new obligations under the Loan, will not affect my duty under the Loan and I will still be obligated to pay the Loan. You may assign all or part of your rights or duties under this Agreement or the Loan Documents without my consent. If you assign this Agreement, all of my covenants, agreements, representations and warranties contained in this Agreement or the Loan Documents will benefit your successors and assigns. I may not assign this Agreement or any of my rights under it without your prior written consent. The duties of the Loan will bind my successors and assigns.

12. AMENDMENT, INTEGRATION AND SEVERABILITY. This Agreement may not be amended or modified by oral agreement. No amendment or modification of this Agreement is effective unless made in writing and executed by you and me. This Agreement and the other Loan Documents are the complete and final expression of the understanding between you and me. If any provision of this Agreement is unenforceable, then the unenforceable provision will be severed and the remaining provisions will still be enforceable.

13. INTERPRETATION. Whenever used, the singular includes the plural and the plural includes the singular. The section headings are for convenience only and are not to be used to interpret or define the terms of this Agreement.

14. NOTICE, FINANCIAL REPORTS AND ADDITIONAL DOCUMENTS. Unless otherwise required by law, any notice will be given by delivering it or mailing it by first class mail to the appropriate party’s address listed in the DATE AND PARTIES section, or to any other address designated in writing. Notice to one Borrower will be deemed to be notice to all Borrowers. I will inform you in writing of any change in my name, address or other application information. I will provide you any financial statement or information you request. All financial statements and information I give you will be correct and complete. I agree to sign, deliver, and file any additional documents or certifications that you may consider necessary to perfect, continue, and preserve my obligations under this Loan and to confirm your lien status on any Property. Time is of the essence.

15. CROSS-DEFAULT. A default under this Agreement or any of the Loan Documents shall be deemed a default under (i) the Commercial Loan Agreement and loan documents executed in connection therewith by the Company dated even date herewith in connection with the $2,000,000 loan made by you to the Company and (ii) the Commerical Loan Agreement and loan documents executed in connection therewith dated even date herewith in connection with the $5,000,000 loan made by you to the Company.
