     less than four (4) Business Days prior to

                                      -7-

 
     the first day of any Quarterly Period (except the second Quarterly Period
     in which a six (6) month LIBO Rate is already in effect, and except as
     otherwise provided below) that Lessee desires that the LIBO Rate for such
     Quarterly Period and the succeeding Quarterly Period be based on a six (6)
     month period, then the LIBO Rate with respect to such two (2) Quarterly
     Periods shall be an interest rate per annum (rounded upwards, if necessary,
     to the next 1/16 of 1%) equal at all times during such two (2) Quarterly
     Periods to the rate of interest at which deposits (in an amount equal to
     the Balance Due as of the first day of the first of such two (2) Quarterly
     Periods) in United States dollars in immediately available funds are
     offered or are available to Lessor's LIBOR Office in the Eurobank interbank
     market at 10:00 a.m. (Pacific Standard Time) two (2) Business Days before
     the first day of the first of such two (2) Quarterly Periods for such six
     (6) month period. Lessee may not elect a six (6) month LIBO Rate with
     respect to any Quarterly Period expiring during the period beginning on the
     date hereof and ending on the first Installment Date after the earlier of
     (i) the Funding Termination Date, and (ii) the earliest date on which the
     Funded Amount equals the Maximum Advance Amount. If Lessor is unable to
     determine the LIBO Rate at any time, or Lessor shall determine that the
     introduction of any change in or in the interpretation of any law makes it
     unlawful, or any central bank or other governmental authority asserts that
     it is unlawful for Lessor to calculate rent based on the LIBO Rate, then
     the LIBO Rate for the applicable Quarterly Period shall be the Corporate
     Base Rate.

     (k)  The definition of LIBO Rent is hereby deleted and replaced with the
                            ---------

          (a) with respect to the period beginning December 2, 1993 and ending
     December 21, 1993 (such period being a portion of the Quarterly Period
     beginning on September 22, 1993 and ending on December 21, 1993), an amount
     equal to $33,373.34; and

          (b) with respect to each Quarterly Period commencing after the date
     hereof, the quotient of (1) the product of (i) the Balance Due as of the
     beginning of the Quarterly Period in which such Installment Date falls
     (such Balance Due shall include the amount of any Advance made on the first
     day of such Quarterly Period), multiplied by (ii) the sum of 1% plus the
     rate obtained by dividing the LIBO Rate by a percentage equal to 100% minus
     the LIBO Reserve Percentage, multiplied by (iii) the number of actual days

                                      -8-

 
     elapsed (including such Installment Date) in the Quarterly Period that
     includes such Installment Date, divided by (2) 360.

     As used herein, "LIBO Reserve Percentage" means the maximum reserve
                      -----------------------
     percentage applicable to Lessor for such Quarterly Period (or if more than
     one such percentage is applicable during such period, the daily average of
     such percentages for those days in such period during which each such
     percentage is applicable) under applicable law, including, without
     limitation, regulations issued from time to time by the Federal Reserve
     Board, for determining the maximum reserve requirement (including, without
     limitation, any emergency, supplemental or other marginal reserve
     requirement) with respect to liabilities or assets consisting of or
     including (x) eurocurrency liabilities in the amount of the above
     referenced portion of the Balance Due and having a maturity substantially
     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
     LIBO Rent, which certificate shall be conclusive and binding for all
     purposes, absent manifest error.

     (l)  The definition of Operative Agreements is hereby deleted and replaced
                            --------------------

          ---------------------------   ---------------                      
replaced with the following:

          41.1 Lessee's Option to Purchase. (a) Subject to the terms and
               ---------------------------
     conditions and provisions set forth in this Section 41.1, Lessee shall have
                                                 ------------
     the option (the "Purchase Option"), to be exercised as set forth below at
                      ---------------
     any time on or before the Option Termination Date (as hereinafter defined),
     to purchase from Lessor at any time during the Fixed Term Lessor's interest
     in the Leased Property. Such option must be exercised by written notice to
     Lessor, which exercise shall be irrevocable; and such exercise notice will

     Lessee's purchase of the Leased Property, which date shall not be more than
     sixty (60) days following Lessor's receipt of such notice but in no event
     later than the Expiration Date, and the closing of the conveyance of the
     Leased Property shall occur on such date. In such event, subject to the
     provisions set forth in this Section 41, on such closing date, Lessor shall
                                  ----------

     in the Leased Property. The purchase price to be paid by Lessee for the
     Leased Property shall be an amount equal to the Balance Due as of the
     closing date of Lessee's purchase of the Leased Property. As a condition to
     Lessor's obligations hereunder, Lessee shall also pay to Lessor all Basic

     date.

     27.  Purchase.  Section 41.2 is hereby deleted and replaced with the
          --------   ------------                                        
following:

          41.2 Expiration Date Obligation to Pay and Purchase. Unless Lessee
               ----------------------------------------------
     shall have exercised the Purchase Option, then, subject to the terms,
     conditions and provisions set forth in this Section 41, Lessee shall be
                                                 ---------- 
     required to purchase all of Lessor's interest in the Leased Property and
     pay to Lessor the Balance Due as of the Expiration Date

                                      -22-

 
     along with all accrued Basic Rent, Additional Rent and other amounts then
     due. Upon receipt of such amount, Lessee shall be deemed to have purchased
     from Lessor, and Lessor shall convey to Lessee, on the Expiration Date all
     of Lessor's interest in the Leased Property. Lessee acknowledges that under
     Section 41 of the Land Lease, Lessee shall be obligated to pay the Balance
     ----------
     Due (as defined in the Land Lease) under the Land Lease and purchase the
     Land simultaneously with the purchase of the Leased Property. Lessee may
     designate, in a notice given to Lessor not less than ten (10) days prior to
     the closing of such purchase (time being of the essence), a transferee to
     whom the 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 transferee shall not cause Lessee to be released, fully or partially,
     from any of its obligations under this Lease, including without limitation
     its obligation to pay the Balance Due on the Expiration Date and all other
     accrued amounts.

     28.  Acceleration of Purchase Obligation.  Section 41.3 is hereby deleted
          -----------------------------------   ------------                  
and replaced with the following:

          41.3  Acceleration of Expiration Date Obligation.  Lessee shall be
                ------------------------------------------                  
     obligated to purchase Lessor's interest in the Leased Property and pay to
     Lessor the Balance Due along with all amounts which have accrued and are
     due and payable hereunder immediately upon the occurrence of any Event of
     Default specified in clauses (k) or (l) of Section 25.1. Further,
                          -----------    ---    ------------ 
     notwithstanding anything contained herein to the contrary, at any time upon
     the occurrence and during the continuance of an Event of Default, if Lessor
     gives Lessee a notice under Section 25.2(a)(i) terminating Lessee's right
                                 ------------------
     of possession (for purposes of this Section 41 such notice being referred
                                         ----------
     to as a "Purchase Acceleration Notice"), Lessee shall be obligated to
              ---------------------------- 
     purchase Lessor's interest in the Leased Property and to pay to Lessor the
     Balance Due along with all 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 by Lessee of a Purchase Acceleration Notice under

                 ------------
     interest in the Leased Property are independent of each other, and
     notwithstanding anything in Section 41.1 to the
                                 ------------

                                      -23-

 
     contrary, unless the Option Termination Date shall have first occurred, the
     Purchase Option shall terminate and be of no further force or effect on the
     date that any Purchase Acceleration Notice is given.

          If Lessee fails to purchase Lessor's interest in the Leased Property
     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 Leased Property to another Person and upon any such subsequent
     sale to any other Person by Lessor of Lessor's interest in the Leased
     Property, 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 not cash), received by Lessor in
     connection with such sale.

     29.  Determination of the Purchase Price.  In Section 41.4, (a) such
          -----------------------------------      ------------          
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 purchase of Lessor's interest in the Leased
     Property 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

                                      -24-

 
     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 5% per annum. If any statute or
     rule of law shall validly limit the amount due under this Section 41.4 to
                                                               ------------
     less than the amount above agreed upon, Lessor or Assignee shall be
     entitled to the maximum amount allowable under such statute or rule of law.

     30.  Purchase Procedure.  In Section 41.5, (a) the phrase "purchase price
          ------------------      ------------                                
therefor" in the first paragraph is hereby deleted and replaced with "Balance
Due (and all other amounts due and owing hereunder)"; (b) the second grammatical
paragraph, the first sentence shall begin as follows:  "If Lessee shall purchase
Lessor's interest in the Leased Property pursuant to Section 41.1(b) or if

Lessee's obligation to pay the Balance Due and purchase the Leased Property is
accelerated pursuant to Section 41.3, Lessee shall deliver the Balance Due to

of the parenthetical in the penultimate sentence in such second grammatical
paragraph:  "and pay to Lessor the Balance Due along with all other amounts due

     shall be subject to the due and timely fulfillment of each of the following
     provisions, the failure of any of which shall render the Remarketing Option
     and Lessee's exercise thereof null and void, in which event, Lessee shall
     be obligated on the Expiration Date to pay to Lessor the Balance Due (and
     all other accrued amounts) and perform its obligations under Section 41.2

     automatically be deemed extended until five (5) Business Days after such
     Expiration Date and the purchase by Lessee under Section 41.2 and payment
                                                      ------------ 
     of the Balance Due and all other amounts due and owing hereunder shall (and
     all other accrued amounts) be consummated on the fifth such Business Day.

     Subparagraph I is hereby deleted and replaced with the following:  "The
