Promissory Note

Date September 26, 2003         x New         ¨ Renewal         Amount $2,000,000         Maturity Date November 21, 2005

FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and severally, if more than one) promises to pay to the order of Lender, its successors and assigns, without setoff, at its offices indicated at the beginning of this Note, or at such other place as may be designated by Lender, the principal amount of Two Million and 00/100 Dollars ($2,000,000), or so much thereof as may be advanced from time to time in immediately available funds, together with interest computed daily on the outstanding principal balance hereunder, at an annual interest rate, and in accordance with the payment schedule, indicated below.

1. Rate

(a) Interest on this Note shall accrue at a per annum rate or rates equal to the LIBOR Rate plus 1.13% per annum.

(b) The “LIBOR Rate” means the interest rate determined by the following formula, rounded upward to the nearest 1/100 of one percent. (All amounts in the calculation will be determined by Lender as of the first day of the interest period.)

Where,

(1) “London Inter-Bank Offered Rate” means the average per annum interest rate at which U.S. dollar deposits would be offered for the “Applicable Interest Period,” as defined below, by major banks in the London inter-bank market, as shown on the Telerate Page 3750 (or any successor page) at approximately 11:00 a.m. London time two (2) London Banking Days before the commencement of the Applicable Interest Period. If such rate does not appear on the Telerate Page 3750 (or any successor page), the rate for that Applicable Interest Period will be determined by such alternate method as reasonably selected by Lender. A “London Banking Day” is a day on which Lender’s London Banking Center is open for business and dealing in offshore dollars.

(2) “Reserve Percentage” means the total of the maximum reserve percentages for determining the reserves to be maintained by member banks of the Federal Reserve System for Eurocurrency Liabilities, as defined in Federal Reserve Board Regulation D, rounded upward to the nearest 1/100 of one percent. The percentage will be expressed as a decimal, and will include, but not be limited to, marginal, emergency, supplemental, special, and other reserve percentages.

(3) “Applicable Interest Period” means each one-month period commencing on the first LIBOR Banking Day, defined below, of each calendar month through and including the day immediately before the first LIBOR Banking Day of the next calendar month. “LIBOR Banking Day” means a day, other than a Saturday or a Sunday, on which Lender is open for business in New York and London and dealing in offshore dollars.

(c) If at any time after the date hereof, the Lender (which shall include, for purposes of this Section, any corporation controlling the Lender) determines that the adoption or modification of any applicable Law regarding taxation, the Lender’s required levels of reserves, deposits, insurance or capital (including any allocation of capital requirements or conditions), or similar requirements, or any interpretation or administration thereof by any Tribunal or compliance of the Lender with any of such requirements, has or would have the effect of (a) increasing the Lender’s costs relating to the loan

evidenced by this Note, or (b) reducing the yield or rate of return of the Lender on such loan, to a level below that which the Lender could have achieved but for the adoption or modification of any such requirements, the Borrower shall, within fifteen (15) days of any request by the Lender, pay to the Lender such additional amounts as (in the Lender’s sole judgment, after good faith and reasonable computation) will compensate the Lender for such increase in costs or reduction in yield or rate of return of the Lender. No failure by the Lender to immediately demand payment of any additional amounts payable hereunder shall constitute a waiver of the Lender’s right to demand payment of such amounts at any subsequent time. Nothing herein contained shall be construed or so operate as to require the Borrower to pay any interest, fees, costs or charges greater than is permitted by applicable Law. For purposes of this Note:

“Laws” means all constitutions, treaties, statutes, laws, ordinances, regulations, rules, order, writs, injunctions, or decrees of the United States of America, any state or commonwealth, any municipality, any foreign country, any territory or possession, or any Tribunal; and

“Tribunal” means any state, commonwealth, federal, foreign, territorial or other court or governmental department, commission, board, bureau, district, authority, agency, central bank, or instrumentality, or any arbitration authority.

Notwithstanding any provision of this Note, Lender does not intend to charge and Borrower shall not be required to pay any amount of interest or other charges in excess of the maximum permitted by the applicable law of the Commonwealth of Virginia; if any higher rate ceiling is lawful, then that higher rate ceiling shall apply, and any payment in excess of such maximum shall be refunded to Borrower or credited against principal, at the option of Lender. The foregoing sentence shall have no effect if under Virginia law Borrower is unable to plead usury as a defense.

2. Accrual Method. Unless otherwise indicated, interest at the Rate set forth above will be calculated by the 365/360 day method (a daily amount of interest is computed for a hypothetical year of 360 days; that amount is multiplied by the actual number of days for which any principal is outstanding hereunder).

3. Rate Change Date. Any Rate based on a fluctuating index or base rate will change, unless otherwise provided, each time and as of the date that the index or base rate changes. In the event any index is discontinued, Lender shall substitute an index determined by Lender to be comparable, in its sole discretion.

4. Payment Schedule. All payments received hereunder shall be applied first to the payment of any expense or charges payable hereunder or under any other loan documents executed in connection with this Note, then to interest due and payable, with the balance applied to principal, or in such other order as Lender shall determine at its option.

The principal of and interest on this Note shall be due and payable as follows:

5. Automatic Payment.

Borrower has elected to authorize Lender to effect payment of sums due under this Note by means of debiting Borrower’s account number /VA. This authorization shall not affect the obligation of Borrower to pay such sums when due, without notice, if there are insufficient funds in such account to make such payment in full on the due date thereof, or if Lender fails to debit the account.

6. Waivers, Consents and Covenants. Borrower, any indorser or guarantor hereof, or any other party hereto (individually an “Obligor” and collectively “Obligors”) and each of them jointly and severally: (a) waive presentment, demand, protest, notice of demand, notice of intent to accelerate, notice of acceleration of maturity, notice of protest, notice of nonpayment, notice of dishonor, and any other notice required to be given under the law to any Obligor in connection with the delivery, acceptance, performance, default or enforcement of this Note, any indorsement or guaranty of this Note, or any other documents executed in connection with this Note or any other note or other loan documents now or hereafter executed in connection with any obligation of Borrower to Lender (the “Loan Documents”); (b) consent to all delays, extensions, renewals or other modifications of this Note or the Loan Documents, or waivers of any term hereof or of the Loan Documents, or release or discharge by Lender of any of Obligors, or release, substitution or exchange of any security for the payment hereof, or the failure to act on the part of Lender, or any indulgence shown by Lender (without notice to or further assent from any of Obligors), and agree that no such action, failure to act or failure to exercise any right or remedy by Lender shall in any way affect or impair the obligations of any Obligors or be construed as a waiver by Lender of, or otherwise affect, any of Lender’s rights under this Note, under any indorsement or guaranty of this Note or under any of the Loan Documents; and (c) agree to pay, on demand, all costs and expenses of collection or defense of this Note or of any indorsement or guaranty hereof and/or the enforcement or defense of Lender’s rights with respect to, or the administration, supervision, preservation, or protection of, or realization upon, any property securing payment hereof, including, without limitation, reasonable attorney’s fees, including fees related to any suit, mediation or arbitration proceeding, out of court payment agreement, trial, appeal, bankruptcy proceedings or other proceeding, in the amount of 25% of the principal amount of this Note, or such greater amount as may be determined reasonable by any arbitrator or court, whichever is applicable.

2

7. Prepayments. Prepayments may be made in whole or in part at any time without penalty or premium. All prepayments of principal shall be applied in the inverse order of maturity, or in such other order as Lender shall determine in its sole discretion. If there is a prepayment of any such principal, because of acceleration or otherwise, the prepayment shall be accompanied by the amount of accrued interest on the amount prepaid.

8. Delinquency Charge. To the extent permitted by law, a delinquency charge may be imposed in an amount not to exceed four percent (4%) of any payment that is more than fifteen days late.

9. Events of Default. The following are events of default hereunder: (a) the failure to pay or perform any obligation, liability or indebtedness of any Obligor to Lender, or to any affiliate or subsidiary of Bank of America, N.A. Corporation, whether under this Note or any Loan Documents, as and when due (whether upon demand, at maturity or by acceleration); (b) the failure to pay or perform any other obligation, liability or indebtedness of any Obligor to any other party; (c) the death of any Obligor (if an individual); (d) the resignation or withdrawal of any partner or a material owner/guarantor of Borrower, as determined by Lender in its sole discretion; (e) the commencement of a proceeding against any Obligor for dissolution or liquidation, the voluntary or involuntary termination or dissolution of any Obligor or the merger or consolidation of any Obligor with or into another entity; (f) the insolvency of, the business failure of, the appointment of a custodian, trustee, liquidator or receiver for or for any of the property of, the assignment for the benefit of creditors by, or the filing of a petition under bankruptcy, insolvency or debtor’s relief law or the filing of a petition for any adjustment of indebtedness, composition or extension by or against any Obligor; (g) the determination by Lender that any representation or warranty made to Lender by any Obligor in any Loan Documents or otherwise is or was, when it was made, untrue or materially misleading; (h) the failure of any Obligor to timely deliver such financial statements, including tax returns, other statements of condition or other information, as Lender shall request from time to time; (i) the entry of a judgment against any Obligor which Lender deems to be of a material nature, in Lender’s sole discretion; (j) the seizure or forfeiture of, or the issuance of any writ of possession, garnishment or attachment, or any turnover order for any property of any Obligor; (k) the determination by Lender that it is insecure for any reason; (l) the determination by Lender that a material adverse change has occurred in the financial condition of any Obligor; or (m) the failure of Borrower’s business to comply with any law or regulation controlling its operation.

10. Remedies upon Default. Whenever there is a default under this Note (a) the entire balance outstanding hereunder and all other obligations of any Obligor to Lender (however acquired or evidenced) shall, at the option of Lender, become immediately due and payable and any obligation of Lender to permit further borrowing under this Note shall immediately cease and terminate, and/or (b) to the extent permitted by law, the Rate of interest on the unpaid principal shall be increased at Lender’s discretion up to the maximum rate allowed by law, or if none, 25% per annum (the “Default Rate”). The provisions herein for a Default Rate shall not be deemed to extend the time for any payment hereunder or to constitute a “grace period” giving Obligors a right to cure any default. At Lender’s option, any accrued and unpaid interest, fees or charges may, for purposes of computing and accruing interest on a daily basis after the due date of this Note or any installment thereof, be deemed to be a part of the principal balance, and interest shall accrue on a daily compounded basis after such date at the Default Rate provided in this Note until the entire outstanding balance of principal and interest is paid in full. Upon a default under this Note, Lender is hereby authorized at any time, at its option and without notice or demand, to set off and charge against any deposit accounts of any Obligor (as well as any money, instruments, securities, documents, chattel paper, credits, claims, demands, income and any other property, rights and interests of any Obligor), which at any time shall come into the possession or custody or under the control of Lender or any of its agents, affiliates or correspondents, any and all obligations due hereunder. Additionally, Lender shall have all rights and remedies available under each of the Loan Documents, as well as all rights and remedies available at law or in equity.

11. Non-waiver. The failure at any time of Lender to exercise any of its options or any other rights hereunder shall not constitute a waiver thereof, nor shall it be a bar to the exercise of any of its options or rights at a later date. All rights and remedies of Lender shall be cumulative and may be pursued singly, successively or together, at the option of Lender. The acceptance by Lender of any partial payment shall not constitute a waiver of any default or of any of Lender’s rights under this Note. No waiver of any of its rights hereunder, and no modification or amendment of this Note, shall be deemed to be made by Lender unless the same shall be in writing, duly signed on behalf of Lender; each such waiver shall apply only with respect to the specific instance involved, and shall in no way impair the rights of Lender or the obligations of Obligors to Lender in any other respect at any other time.

12. Applicable Law, Venue and Jurisdiction. This Note and the rights and obligations of Borrower and Lender shall be governed by and interpreted in accordance with the law of the Commonwealth of Virginia. In any litigation in connection with or to enforce this Note or any indorsement or guaranty of this Note or any Loan Documents, Obligors, and each of them, irrevocably consent to and confer personal jurisdiction on the courts of the Commonwealth of Virginia or the United States located within the Commonwealth of Virginia and expressly waive any objections as to venue in any such courts. Nothing contained herein shall, however, prevent Lender from bringing any action or exercising any rights within any other state or jurisdiction or from obtaining personal jurisdiction by any other means available under applicable law.

13. Partial Invalidity. The unenforceability or invalidity of any provision of this Note shall not affect the enforceability or validity of any other provision herein and the invalidity or unenforceability of any provision of this Note or of the Loan Documents to any person or circumstance shall not affect the enforceability or validity of such provision as it may apply to other persons or circumstances.

14. Binding Effect. This Note shall be binding upon and inure to the benefit of Borrower, Obligors and Lender and their respective successors, assigns, heirs and personal representatives, provided, however, that no obligations of Borrower or Obligors hereunder can be assigned without prior written consent of Lender.

15. Controlling Document. To the extent that this Note conflicts with or is in any way incompatible with any other document related specifically to the loan evidenced by this Note, this Note shall control over any other such document, and if this Note does not address an issue, then each such document shall control to the extent that it deals most specifically with an issue.
