Promissory Notein the original principal amount of up to





---

$1,000,000.00 dated April 28, 2003, executed by the Borrower in favor of the Lender. This Note has been executed and delivered subject to the
following terms and conditions:



1.Repayment Term and Maturity. The
Borrower will pay principal and interest by making monthly payments in the initial amount of Eight Thousand Three Hundred Twenty Six and 66/100 DOLLARS ($8,326.66) commencing on February 1, 2005 and continuing on thefirstday
of each and every month thereafter until all principal and interest and any other sums due hereunder have been paid in full. Notwithstanding the foregoing, the entire indebtedness evidenced by this Note, including, but not limited to, all
outstanding principal and accrued and unpaid interest, shall be due and payable in full on December 1, 2009.



The Borrowers initial monthly payments have been calculated in accordance with the full amortization of the loan evidenced by this Note by level
monthly payments of principal and interest over a five (5) year period at the interest rate applicable on the date hereof. On each Adjustment Date (as herein defined), the amount of the monthly payments will be adjusted so as to provide for
the full amortization of the then outstanding principal at the interest rate established at each Adjustment Date in level monthly payments of principal and interest over the remaining term of the original five (5) year amortization period.



All payments received by the Holder, at the option of the
Holder, shall be applied first to any outstanding charges and expenses incurred by the Holder in connection with this Note or any documents executed in connection with this Note, then to any unpaid and accrued interest and finally to the outstanding
principal due under this Note. The Borrower agrees that the interest shall accrue at the foregoing rate on the unpaid balance before and after maturity, by acceleration or otherwise.



2. Interest. Interest shall accrue on the outstanding principal amount of this Note at a variable rate per annum of four
percentage points (4.00%)in excess of the Prime Rate, with the term Prime Rate meaning the Prime Rate as published from time to time in the Money Rates section of The Wall Street Journal, or in the
event that such rate is no longer published in The Wall Street Journal, a comparable index or reference rate selected by the Lender or other holder, in its sole discretion. The Prime Rate may not necessarily be the Lenders lowest or
best rate. The initial interest rate hereunder is nine percent(9.00%).



The interest rate may be adjusted on the firstday ofJanuary, 2005 and on the first day of each and every month thereafter (or the following business day in the event that such date falls on a
Saturday, Sunday or holiday) until all sums due under the Loan are paid in full without notice of demand (each such day being referred to as an Adjustment Date), which rate shall remain in effect until the succeeding Adjustment Date.



Upon the occurrence of an event of default hereunder, without
in any way affecting the Lenders or other Holders right to accelerate this Note, this Note shall bear interest at a rate which is three percentage points (3.0%) per annum greater than the rate otherwise in effect hereunder.

3.Lawful Interest. Notwithstanding any provisions of this Note, it is the understanding and agreement of the
Borrower and Holder that the maximum rate of interest to be paid by Borrower to the Holder shall not exceed the highest or the maximum rate of interest permissible to be charged by a commercial lender such as Lender to a commercial borrower such as
Borrower under the laws of the Commonwealth of Virginia. Any amounts paid in excess of such rate shall be considered to have been payments in reduction of principal.



4.Late Charge. In the event Borrower fails to pay any installment of principal and/or interest within ten (10) days of when it is
due and payable, without in any way affecting the Holders right to accelerate this Note, a late charge equal to five (5) percent of such late payment shall, at the option of Holder, be assessed against Borrower.



5.Prepayments. The Borrower may prepay the loan in part or in full at any time,
without penalty or premium, upon 7 days prior written notice to Lender. Failing such prior notice, the Borrower shall pay to Lender a prepayment penalty equal to 7 days interest on the principal amount prepaid. Any amounts prepaid shall
be applied first to interest and other charges accrued in connection with the Loan to the date of prepayment and then to principal.



6.Financial Information. Promptly upon Holders reasonable request, Borrower shall deliver to Holder such documentation and information about the
Borrowers financial condition, business and/or operations as Holder may, at any time and from time to time, request, including without limitation, such books, records and reports as may be required under Commercial Loan Agreement between
Borrower and Lender of even date herewith (the Commercial Loan Agreement; capitalized terms used in this Note and not otherwise defined shall have the meanings assigned in the Commercial Loan Agreement).

Borrower to pay or perform any of Borrowers liabilities or obligations to Holder (whether under this Note or otherwise and whether now existing or hereafter incurred), including without limitation, any installment of principal and/or interest

the same in the event of any subsequent default.
