An Event of Default under that ce1iain revolving capital line of credit agreement in a maximum outstanding amount of Ten Million dollars ($10,000,000) and/or the failure to pay any principal or interest payment at the times stated herein  shall constitute  an Event of Default hereunder: Upon any such Event of Default, the entire principal balance hereof, all accrued  and unpaid interest  thereon, and all other applicable  fees, costs and charges, if any, shall   at once become due and payable at the option of the holder of this Note.

5.Default Interest. Notwithstanding the ent1y of any decree, order, judgment or other judicial action under, pursuant to, in connection with, or otherwise concerning this Note, upon the occurrence of an Event of Default of this Note (whether by acceleration, declaration, extension or otherwise), the Maker promises to pay to the Lender whenever demanded by the Lender interest on this Note and all other amounts then and thereafter due and payable hereunder at a per annum rate of interest (the "Default Rate") equal to the lesser of (i) five percent (5.0%) per annum in excess of the interest rate set forth in Section 1 above, or (ii) the highest rate allowable by law from the date of such Event of Default for so long as such Event of Default continues until payment in full of the unpaid principal balance of this Note, all accrued and unpaid interest thereon and any and all other amounts due or payable hereunder.

THE LENDER, THE MAKER AND ANY OTHER PARTY LIABLE HEREON IN ANY CAPACITY, WHETHER AS SURETY, GUARANTOR, OR OTHERWISE, EACH WAIVES TRIAL BY JURY WITH RESPECT TO ANY ACTION, CLAIM, SUIT OR PROCEEDING IN RESPECT OF OR ARISING OUT OF THE LOAN EVIDENCED HEREBY AND/OR THE CONDUCT OF THE RELATIONSHIP BETWEEN THE LENDER, THE MAKER AND/OR ANY OTHER PARTY LIABLE HEREON IN ANY CAPACITY, WHETHER AS SURETY, GUARANTOR, OR OTHERWISE. THIS WAIVER IS KNOWINGLY, WILLINGLY AND VOLUNTARILY MADE BY MAKER, AND MAKER HEREBY REPRESENTS THAT NO ORAL OR WRITTEN STATEMENTS HAVE BEEN MADE BY ANY PARTY TO INDUCE THIS WAIVER OF TRIAL BY JURY OR TO IN ANY WAY MODIFY OR NULLIFY ITS STATED EFFECT.

8.Costs of Collection. The Maker promises to pay all third-party costs and expenses incurred in connection with collection hereof or in the protection or realization of any collateral now or hereafter given as security for the repayment hereof, including reasonable attorneys' fees, upon the occurrence of an Event of Default in the payment of the principal of this Note or interest hereon when due, whether at Maturity, as herein provided, or by reason of acceleration of Maturity under the tenns hereof, whether suit be brought or not.

9.Lender's Rights and Remedies. The failure of the Lender to exercise the option for acceleration of Maturity, foreclosing, or either, following any Event of Default as aforesaid or to exercise any other option granted to it hereunder, in any one or more instances, or the acceptance by the Lender of partial payments or partial performance, shall not constitute a waiver of any such Event of Default, but such options shall remain continuously in force. Acceleration of Maturity, once claimed hereunder by the Lender, may at its option be rescinded by written acknowledgment to that effect but the tender and acceptance of partial payment or partial perfonnance alone shall not in any way affect or rescind such acceleration of maturity. The rights, remedies and powers of the Lender, as provided in this Note, are cumulative and concurrent, and may be pursued singly, successively, or together against the Maker, and/or any security given at any time to secure the payment hereof, all at the sole discretion of the Lender.

10.Lawful Interest. Notwithstanding anything to the contrary contained herein, the effective rate of interest on the obligation evidenced by this Note shall not exceed the lawful maximum rate of interest permitted to be paid. Without limiting the generality of the foregoing, in the event the interest charged hereunder results in an effective rate of interest higher than that lawfully permitted to be paid, then such charges shall be reduced by the sum sufficient to result in an effective rate of interest permitted by law and any amount which would exceed the highest lawful rate already received and held by the Lender shall be applied to a reduction of principal and not to the payment of interest.

11.Partial Invalidity. In the event any one or more of the provisions contained in this Note shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Note, but this Note shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein or therein.

12.Amendment. This Note may not be changed orally, but only by an agreement in writing signed by the parties against whom enforcement of any waiver, change, modification or discharge is sought.

13.Patriot Act Notice. To help fight the funding of ten-orism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. For purposes of this section, account shall be understood to include loan accounts.

14.Business Purpose. The Maker warrants and represents that the loan evidenced hereby is being made for business or commercial purposes.

15.Governing Law. This Note shall be governed in all respects by the laws of the Commonwealth of Virginia and shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. The Maker hereby consents to be sued in an appropriate court in the Commonwealth of Virginia in any action to enforce the provisions of this Note. The Maker waives any objection to the venue of any action filed by the holder of this Note against the Maker in any court in the Commonwealth of Virginia and waives any claim of forum non conveniens or for transfer of any such action to any other court.

16.Limitation on Issuance of Debt. The Maker hereby agrees not to, without the prior written consent of the Lender, to issue any new corporate indebtedness of the Maker unless such indebtedness shall be expressly subordinate by its terms to the repayment of this Note; provided however, nothing herein shall limit the Maker from (i) providing its corporate guarantee for indebtedness related to its normal and recun-ing business lines from time to time, or (ii) making payments under its existing corporate indebtedness, or making any modifications thereto that may occur from time to time.
