Amendment of Original Note. The provisions of the Original Note are hereby amended in the following manner: Page 2 of 9 Pages 1.1 Interest Rate. The interest rate provisions of pages 3 through 6 of the Original Note are deleted and the following is inserted as if originally set forth therein: FOR VALUE RECEIVED, the Borrower promises to pay to the order of the Bank, at its principal office in Baltimore, Maryland, or at such other place or to such other party as the holder hereof may from time to time designate, the principal sum of ELEVEN MILLION EIGHT HUNDRED THOUSAND AND 00/100 DOLLARS ($11,800,000.00), with interest on the unpaid principal balance from the date of this Note, until paid, at the rate of one half percent (0.5%) per annum in excess of the Prime Rate (as hereinafter defined). 1.2 Prime Rate. The following is inserted as if originally set forth in the Original Note: Prime Rate. "Prime Rate" means the prime commercial lending rate of the Bank as publicly announced to be in effect from time to time. The Prime Rate is not necessarily the lowest rate of interest charged by the Bank for commercial or other types of loans. It is understood that the Prime Rate is only one of the bases for computing interest on loans made by the Bank and that by basing interest on the Prime Rate, the Bank has not committed to charge and the Borrower has not in any way bargained for interest based on a lower or the lowest rate at which the Bank may now or in the future make loans to other borrowers. Any change in the rate of interest as a result of a change in the Prime Rate shall be effective as of the date of the change in the Prime Rate. 1.3 Repayment and Maturity Date of Loan. The first unnumbered paragraph on page 3 of the Original Note is deleted and the following is inserted as if originally set forth therein: The loan shall be repaid on a fifteen (15) year schedule of one hundred seventy-nine (179) consecutive installments of Sixty Five Thousand Nine Hundred Twenty One and 79/100 Dollars ($65,921.79) in principal together with any and all accrued interest Page 3 of 9 Pages thereon commencing August 1, 1994, and continuing on the first day of each month thereafter until June 1, 2009, and a payment on July 1, 2009, at which time the entire unpaid balance of principal and any accrued but unpaid interest, if not sooner paid, shall be due and payable in full; provided, however, that the entire unpaid principal and any accrued but unpaid interest, if not sooner paid, shall be due and payable on July 1, 1999, or July 1, 2004, at the Bank's sole and absolute discretion if the Bank provides the Borrower with written notice no later than April 1, 1999, or April 1, 2004, as the case may be, of its intention to call this Note (the "Call"). Any change in the rate of interest as a result of a change in the Prime Rate shall be effective as of the date of the change in the Prime Rate. 1.4 Loan Extension Fee. The sixth full paragraph of the Original Note is deleted and the following is inserted as if originally set forth therein: Loan Extension Fee. Borrower has paid to Bank a loan extension fee in the amount of one half percent (0.5%) of the principal amount of the Loan, or Fifty-Nine Thousand and 00/100 Dollars ($59,000.00) 1.5 Notices.

In making this waiver, the holder of this Note and Borrower acknowledge and agree that any and all claims made by the holder of this Note against Borrower and all Page 6 of 9 Pages claims made by the Borrower against the holder of this Note shall be heard by a judge of a court of proper jurisdiction and shall not be heard by a jury. The holder of this Note and Borrower acknowledge and agree that this waiver of trial by jury is a material element of the consideration for this transaction.
