Lessee under the Lease as of the date of Lessee's notice to Lessor and (v) 
the Lessee shall faithfully continue to fulfill all of its obligations under 
the Lease after such notice including the payment of any rent or additional 
rent as the same may become due prior to the early termination of the Lease.

deleted in its entirety.

      4.  Nondisturbance of Lessee.  Section 14 of the Lease shall be 
amended by adding the following at the end thereof:

      As a condition of Lessee's delivering such a subordination instrument 
      as contemplated in the preceding sentence, Lessor shall deliver to 
      Lessee a nondisturbance and attornment agreement (a "Nondisturbance 
      Agreement") executed by Lessee and any party (a "Mortgagee') holding a 
      mortgage, deed of trust, any other instrument in the nature of a 
      mortgage or any instrument effecting an assignment of rents and/or 
      leases (each, a "Security Instrument") covering any portion of the 
      Leased Premises, and (a) with respect to any Security Instrument which 
      affects the Leased Premises as of March 31, 1991, Lessor shall use its 
      best efforts to deliver to Lessee a Nondisturbance agreement and (b) 
      with respect to any Security Instrument which affects the Leased 
      Premises after March 31, 1991, Lessor shall deliver to Lessee a 
      Nondisturbance Agreement at the request of the Lessee.  Such 
      Nondisturbance Agreement shall provide (a) that in the event of an 
      entry by the Mortgagee pursuant to its Security Instrument, a 
      foreclosure of the Security Instrument, the Mortgagee's taking 
      possession of any portion of any portion of the Leased Premises by 
      deed in lieu of the Mortgagee's exercising its rights under the 
      Security Instrument, or the exercise by the Mortgagee of any of its 
      rights under the Mortgage, (i) the Mortgagee shall not disturb 
      Lessee's right of possession of the Leased Premises under the terms of 
      this Lease so long as Lessee is not in default beyond any applicable 
      grace period in the performance of its obligations under this Lease, 
      and (ii) Lessee will attorn to and recognize the Mortgagee and any 
      successor in interest to the Mortgagee, including any purchaser at 
      foreclosure, as its landlord under this Lease for the remainder of the 
      term of this Lease (as the same may be modified by the terms of this 
      Lease) upon the same terms and conditions as are set forth in this 
      Lease and Lessee will pay and perform all of its obligations as tenant 
      pursuant to this lease, and (b) such other terms and conditions as the 
      Mortgagee or Lessee shall reasonably request.

      5.  No Defaults.  Each of Lessor and Lessee agrees that, as of the 
date hereof, the Lease is in full force and effect, that, to the best of its 
knowledge, no default by the other party exists, and that the Lessee has 
paid to Lessor all amounts of rent, additional rent and other sums payable 
to Lessor by Lessee which are due and payable under the Lease.

      6.  Miscellaneous.  (a)  The Lease is hereby amended so that each and 
every reference therein to the Lease shall be deemed to refer to the Lease 
as amended hereby.  (b)  Except as modified herein, all terms and conditions 
of the Lease shall remain in full force and effect.

      IN WITNESS WHEREOF, the parties hereto have executed this Lease 
Amendment Agreement as of the date first written above.
