phrase "(any of the events)") the following:

          "or (c) if, as a result of the Lessee paying any
     Transaction Expenses (as defined in the Refunding Agreement,
     dated as of December 1, 1999, among Lessee, Philip Morris
     Capital Corporation, Lessor and certain other parties (such

     from time to time, being referred to herein as the
     "Refunding Agreement") the Owner Participant shall be
     required to include any amount in its gross income; or

          (d) if Section 467 of the Code or the regulations
     thereunder shall apply to any Rent paid on or after the
     Refunding Date (as defined in the Refunding Agreement) with
     the result that the Owner Participant is required to include

     accounting regularly utilized by the Owner Participant
     (i.e., the accrual method)".

     (b)  Section 3.1 is hereby amended by replacing the phrase
"(any of the events described in these subsections (a)(2) or (b)
hereof being referred to hereinafter as a "Loss")" with the
following:

          "(any of the events described in these subsections
     (a)(2), (b), (c) or (d) being referred to hereinafter as a
     "Loss")".

     Section 3.  Excluded Events. (a)  Section 6(1)(e) is hereby
amended by adding after the phrase "Effective Date;" the
following:

          "provided, further, that with regard to Losses
          described in Section 3.1(c) and (d) hereof only, for
          purposes of this Section 6(1)(e) change in tax law
          shall mean only changes in the Code enacted after the
          Refunding Date (as defined in the Refunding
          Agreement);".

     (b)  Section 6(2) is hereby amended by adding at the end of
the proviso thereto and before the period the following:

          "or Section 3.1(c) or (d)".

     Section 4.  Counterpart Execution.  This Amendment may be
executed by the parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original,
but all such counterparts shall together constitute but one and
the same instrument.

     Section 5.  Ratification of the Tax Indemnity Agreement. As
amended by this Amendment, the Tax Indemnity Agreement is in all
respects ratified, approved and confirmed, and the Tax Indemnity
Agreement and this Amendment shall together constitute one and
the same instrument.

     Section 6.  Governing Law.  This Amendment has been
delivered in, and shall in all respects be governed by, construed
in accordance with, the laws of the State of New York applicable
to agreements made and to be performed entirely within such
State, including such laws applicable to matters of construction,
validity and performance.

     Section 7.  No Duplication of Payment.  Section 21 is hereby
amended by adding, after the phrase "Section 7 hereof" the
following:

          "or the payment made pursuant to Section 2.01(d) of the
     Refunding Agreement (with respect to the income attributable
     to the payment pursuant to Section 2.01(c) of the Refunding
     Agreement).  For the avoidance of doubt, the parties confirm
     that Section 4 hereof shall have no application to any
     payments made pursuant to the Refunding Agreement or any tax
     benefits arising therefrom".

     IN WITNESS WHEREOF, the Owner Participant and the Lessee
have caused this Amendment to be duly executed by their
respective officers hereunto duly authorized as of the date set
