inserted after Section 1.2:
               ----------- 

          1.3. Lessor's Option to Renew. If Lessee has not delivered to Lessor a
               ------------------------

     an additional term of eight (8) years ending on the eighth anniversary date
     of the Expiration Date by notifying Lessee in writing of such renewal at
     least ninety (90) days, but not more than one hundred eighty (180) days,

     the same as such Quarterly Period and (y) any other category of liabilities
     which includes deposits by reference to which the LIBO Rate is to be
     determined. Lessor shall submit a certificate to Lessee which shall set
     forth in reasonable detail the basis for, calculation of and the amount of

     conveyance shall be made (if other than to Lessee), in which case such
     conveyance shall (subject to the terms and conditions set forth herein) be
     made to such designee; provided, however, that such designation of a

     obligation to pay the Balance Due on the Expiration Date and all other
     accrued amounts.

     26.  Acceleration of Purchase Obligation.  Section 41.3 is hereby deleted
          -----------------------------------   ------------

     amounts which have accrued and are payable hereunder on the date which is
     ten (10) business days following Lessee's receipt of such Purchase
     Acceleration Notice. If Lessee's obligations under this Section 41.3 take
     place on a date other than an Installment Date, Basic Rent shall be
     prorated to such date. Lessee acknowledges that its receipt of a Purchase
     Acceleration Notice under this Section 41.3 shall also constitute a receipt
                                    ------------

     the date that any Purchase Acceleration Notice is given.

          If Lessee fails to purchase Lessor's interest in the Land and pay the
     Balance Due along with all other amounts as provided for in the preceding
     paragraph on the tenth (10th) Business Day following Lessee's receipt of
     the Purchase Acceleration Notice, then, Lessor shall be free to sell the
     Land to another Person and upon any such subsequent sale to any other
     Person by Lessor of Lessor's interest in the Land, Lessor shall be entitled
     to recover from Lessee, and Lessee shall upon demand pay to Lessor, an
     amount equal to (i) the Balance Due, plus (ii) the amount of all Basic
                                          ---- 
     Rent, Additional Rent and other sums payable hereunder to and including the
     date of such demand (including, without limitation, Breakage Amounts and
     all costs and expenses incurred by Lessor in effectuating its remedies and
     making such sale or sales), minus (iii) the amount of all consideration (on
                                 -----
     a present value basis determined by the application of a discount factor
     (per annum) equal to five percent (5%) to the extent such consideration is

          -----------------------------------      ------------          
Section shall hereafter be entitled "Breakage"; (b) the first grammatical
                                     --------                            
paragraph is hereby deleted; (c) the remainder of said Section is hereby deleted
and replaced with the following:

          In addition to all other amounts owed to Lessor hereunder, if Lessee's
     payment of the Balance Due and

                                      -13-

 
     purchase of Lessor's interest in the Land occurs on a date other than the
     LIBO Last Day (defined below), and if the LIBO Rate for the three (3) month
     period commencing on the date on which the Balance Due is paid is less than
     the LIBO Rate in effect during the Quarterly Period in which such payment
     occurs, then Lessee shall pay to Lessor on such date as an additional
     component of the Balance Due, the Breakage Amount (defined below). If
     Lessee's payment of the Balance Due occurs when a six (6) month LIBO Rate
     is in effect and on a date other than the second Installment Date of such
     period, the Breakage Amount shall be an amount equal to the present value
     of the difference between (A) the portion of the Basic Rent payments for
            ---------- 
     the two (2) Quarterly Periods for which such six (6) month LIBO Rate
     applies (prorated for the number of days in the period beginning on the
     date of such purchase and ending on the second Installment Date occurring
     in such six (6) month period with respect to which such six (6) month LIBO
     Rate applies), and (B) an amount equal to what the portion of the Basic
     Rent for such two Quarterly Periods (prorated for the number of days in the
     period beginning on the date on which such purchase occurs and ending on
     the second Installment Date occurring in such six (6) month period with
     respect to which such six (6) month LIBO Rate applies) would have been had
     the Basic Rent for such two (2) Quarterly Periods been calculated using the
     three (3) month LIBO Rate in effect on the date of such purchase. If
     Lessee's payment of the Balance Due occurs when a three (3) month LIBO Rate
     is in effect on other than the last day of a Quarterly Period, the Breakage
     Amount shall be an amount equal to the present value of the difference
                                                                 ---------- 
     between (A) the portion of the Basic Rent payment for such Quarterly Period
     in which such purchase occurs (prorated for the number of days during the
     period beginning on the date of such purchase and ending on Installment
     Date at the end of such Quarterly Period) and (B) an amount equal to what
     the portion of the Basic Rent payment for such Quarterly Period (prorated
     for the number of days in the period beginning on the date of such purchase
     and ending on the Installment Date at the end of such Quarterly period)
     would have been had the Basic Rent for such Quarterly Period been
     calculated using a three (3) month LIBO Rate in effect on the date of such
     purchase. In either case, such difference shall be discounted at a rate of
