called "Tenant."

                                    RECITALS

     1.  Lessor and Tenant entered into an agreement of lease
         effective as of October 1, 1980 and amended it by Amendment
         of Lease dated June 20, 1984 (collectively, the "Initial
         Lease");

     2.  Lessor and Tenant amended the Initial Lease and restated it
         in full in one unified document by Amended and Restated
         Lease, dated as of July 1, 1996, and amended it by First
         Amendment to Amended and Restated Lease, dated as of May 1,

     3.  Lessor and Tenant want to further amend the Lease as provided
         herein to reflect the intention of the parties upon entering
         into the Lease.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the sufficiency of which is hereby acknowledged, the
parties agree as follows:

     1. Subsection 4(a)(ii) of the Lease is hereby amended in its entirety to
read as follows:

          "(ii) to the Lessor directly, as supplemental rent, the difference
     between the applicable amount set forth in SUBSECTION 4(a)(iii) below and
     the amount paid by the Tenant pursuant to SUBSECTION 4(a)(i) above;
     provided, however, if the Tenant has received notice from the Trustee that
     a default or Event of Default under the Agreement has occurred and is
     continuing, all supplemental rent payments shall be paid to the Trustee for
     the account of the Lessor. All payments of supplemental rent shall be made
     in substantially equal monthly installments in advance on the first day of
     each and every remaining calendar month during the Term, with any necessary
     adjustments


<PAGE>

     being paid by the Tenant (or credited against future payments of
     supplemental rent) as promptly as practicable (but in no event more than 30
     days) after the end of the applicable lease year."

     2. Subsection 4(a)(iii) of the Lease is hereby amended in its entirety to
read as follows:

          "(iii) The amount to be used in calculating supplemental rent for the
     lease year commencing on May 1, 1998 shall be $461,239.00 (the "Escalation
     Base"). The amount to be used in calculating supplemental rent for the
     lease year commencing on May 1, 1999 shall be the Escalation Base increased
     by the percentage increase, if any, in the CPI (hereinafter defined) for
     the last reported month available to the public on April 1, 1999 as
     compared to the CPI for the same month in 1998 (the "Base CPI"). The amount
     to be used in calculating supplemental rent for each lease year after the
     lease year commencing on May 1, 1999 shall be the Escalation Base increased
     by the percentage increase, if any, in the last reported month available to
     the public on April 1 of the next preceding lease year as compared to the
     Base CPI. On or before April 15, 1999 and on or before each April 15
     thereafter during the Term, Lessor shall provided Tenant with written
     notice of the amount to be used in calculating supplemental rent for the
     next succeeding lease year and the calculation for determining such amount.
     Notwithstanding the result of any calculation of supplemental rent
     hereunder, in no event shall supplemental rent for any lease year be less
     than supplemental for the preceding lease year."

     3. Lessor hereby acknowledges receipt of all amounts owed pursuant to
SUBSECTIONS 4(a)(ii) and (4)(a)(iii) of the Lease prior to the date of this
Second Amendment to Amended and Restated Lease.

     4. Except as modified by this Second Amendment to Amended and Restated
Lease, the Lease remains in full force and effect.
