         A.      Versar and Geomet are parties to a certain Financing and
Security Agreement, along with the Lender dated March 31, 1997 (the Financing
and Security Agreement as thereafter amended, modified and renewed from time to
time, is called the "Financing Agreement").

         B.      Pursuant to the Financing Agreement the Lender has agreed,
among other things, to make available to the Borrowers a revolving credit
facility (the "Revolving Loan") in the maximum principal amount of Six Million
Five Hundred Thousand Dollars ($6,500,000) to be

used by the Borrowers to finance Receivables and for working capital, all as
more fully described in the Financing Agreement.

         C.      The Borrowers have requested that the Lender extend the
maturity of the Revolving Loan and amend certain provisions of the Financing
Agreement, and the Lender has agreed on the condition, among others, that the
Borrowers execute and deliver this Agreement.

         D.      All capitalized terms used herein and not otherwise defined
shall have the meanings given to such terms in the Financing Agreement.

         NOW, THEREFORE, in consideration of the premises, the mutual
agreements herein contained, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Borrowers and the
Lender hereby agree as follows:

         1.      Recitals.  The parties hereto acknowledge and agree that the
above Recitals are true and correct in all respect and that the same are
incorporated herein and made a part hereof by reference.

         2.      Definitions.   Effective as of the date hereof, the following
definitions are added to Section 1.01 of the Financing Agreement:

                          "EBITDAR" means as to the Borrowers for any period of
         determination thereof, the sum of (a) EBITDA, plus (b) rent expense
         for such period.

                          "Fixed Charge Coverage Ratio" means the ratio of (i)
         EBITDAR to (ii) the sum of (a) interest expense, plus (b) required

         scheduled and/or paid in the prior twelve (12) month period, plus (c)
         rent expense.

                          "Funded Debt" means for any period of determination
         thereof an amount equal to the sum of all Indebtedness for Borrowed
         Money (including, but not limited to senior debt, stockholder debt,
         subordinated debt, the value of all capitalized leases, all letters of
         credit issued on the account of any Borrower, and estimated
         liabilities under
