                              W I T N E S S E T H:

         WHEREAS, that certain Mortgage Loan Agreement (the "Mortgage Loan

                  Capital Expenditures which exceed in the aggregate (on a
                  noncumulative basis, with the effect that amounts not expended
                  in any Fiscal Year may not be carried forward to a subsequent
                  period) Forty Million Dollars ($40,000,000) in any Fiscal
                  Year.

         2. LOAN HOLDBACK. Section 2.02 as previously modified by the Third
Amendment is hereby modified in its entirety to read as follows:

                  2.02 LOAN HOLDBACK. The amount of One Million One Hundred
                  Twenty Thousand Dollars ($1,120,000.00) shall not be disbursed
                  to Borrower at Closing, and shall constitute the "Interior
                  Improvement Holdback". The Interior Improvement Holdback shall
                  be disbursed to Borrower upon the substantial completion by
                  Borrower of the interior improvements to the Mortgaged
                  Property in a lien free manner to the satisfaction of Bank.
                  The Borrower agrees to substantially complete the interior
                  improvements not later than March 2, 2000. The interior
                  improvements shall be deemed to be substantially completed at
                  such time as (a) Borrower has obtained a Certificate of
                  Occupancy or Completion for the premises and improvements, and
                  (b) Borrower has obtained a contractor's final lien release
                  from all contractors who have worked on the interior
                  improvements, and (c) Bank's inspector (I.E., an inspector
                  designated by Bank) has inspected the interior improvements
                  and has verified to Bank that the interior improvements have
                  been

<PAGE>   2

                  substantially completed and (d) Borrower has furnished to Bank
                  an updated endorsement to the title policy insuring the
                  Mortgage confirming the absence of liens on the Mortgaged
                  Property. In the event that Borrower fails to substantially
                  complete the interior improvements in accordance with this
                  Section 2.02 on or before March 2, 2000, then Bank shall not
                  be obligated to advance the Interior Improvement Holdback and
                  at the option of Bank the amount of the Loan shall be deemed
                  reduced by the amount of the Interior Improvement Holdback.
                  The failure of Borrower to substantially complete the interior
                  improvements on or before March 2, 2000 in accordance with
                  this Section 2.02 shall not be deemed to constitute a Default
                  under this Agreement and the only consequence of such failure
                  shall be a reduction in the amount of the Loan, but the
                  foregoing shall not be deemed to permit any construction liens
                  to attach to the Mortgaged Property. The Interior Construction
                  Holdback shall not be deemed an advance of funds to the
                  Borrower and shall not bear interest unless and until such
                  funds are advanced to Borrower.

         3. REAFFIRMATION. Except as expressly modified herein, the Mortgage
Loan Agreement, as previously amended, is hereby reaffirmed in its entirety.

         Section 9 is hereby amended by the addition of the following
Subsection G:

         G.       EXCISE TAX TREATMENT. If any of the payments or benefits to be
                  received by Employee in connection with a Change in Control
                  (as defined in Subsection 9E.) pursuant to the terms of this
                  agreement or any other plan, arrangement or agreement (such
                  payments or benefits the "Total Payments") will be subject to
                  any excise tax imposed by Section 4999 of the Internal Revenue

                  subtracting the net amount of federal, state and local income
                  taxes on such Total Payments and the amount of excise tax to
                  which the Employee would be subject in respect of such
                  unreduced Total Payments).
