        the outstanding principal balance of the Mortgage Loan after such
        principal payment is not greater than One Million Four Hundred Forty
        Seven Thousand One Hundred Seventy One and 57/100 Dollars
        ($1,447,171.57); and shall on July 30, 2002 make a principal payment to
        Lender, if necessary, so that the outstanding principal balance of the
        Mortgage Loan after such principal payment is not greater than Nine
        Hundred Twenty Two Thousand One Hundred Seventy One and 57/100 Dollars
        ($922,170.57); and shall on July 30, 2003 make a principal payment to
        Lender so that all sums due and owing to Lender under the Mortgage Loan
        have been paid.

        6. This Second Amendment to Loan and Security Agreement shall be

sum of Fifty Thousand Dollars ($50,000)(the "Effective Date"), which sum
represents the fee payable to Lender for extending the Mortgage Loan Maturity

Representations contained in the Amended Agreement and confirms that all
statements contained therein continue to be true, accurate and correct as of the
date hereof.

term, provision or section contained in this Second


                                      -2-

Amendment to Loan and Security Agreement, this Second Amendment to Loan and
Security Agreement shall not be construed more strictly against any one party
