          1.1 By inserting in Section 17(e)(1)(A) after "5.06," the

          1.2 By deleting the reference to "or" before "5.23" in Section

          1.3 By amending and restating Section 17(h) in its entirety as
follows:

<PAGE>
          "(h)(i) the Lessee, the Guarantor or any Subsidiary Guarantor shall
     fail to make any payment on any Debt of the Lessee, the Guarantor or a
     Subsidiary Guarantor or any guaranty obligation in respect of the Debt
     of any other Person, and, in each case, such failure relates to Debt
     having a principal amount of $3,000,000 or more, when the same becomes
     due and payable (whether by scheduled maturity, required prepayment,
     acceleration, demand or otherwise), (ii) any other event shall occur or
     condition shall exist which shall constitute an event of default (after
     giving effect to any applicable grace periods and waivers) under any
     agreement or instrument relating to any such Debt, if the effect of such
     event or condition is to accelerate, or to permit the acceleration of,
     the maturity of such Debt having a principal amount of $3,000,000 or
     more, (iii) any such Debt having a principal amount of $3,000,000 or

     occurrence, without the consent of Lessor, of any of the events
     specified in Section 3 of that certain Agreement and Amendment dated as
     of April 13, 2000 between Lessee and Lessor; provided that a breach of
     this clause (iv) that does not also result in a breach of Section 5.07
     of the Participation Agreement shall not be deemed to be a violation of
     this Lease for any purposes other than those specified in Section 20(b)
     of that certain Security Agreement dated as of July 28, 2000 by Lessee,
     Guarantor, Viskase Holding Corporation and Viskase Sales Corporation in
     favor of Owner Trustee and Owner Participant."

          1.4 By adding in Section 21.01 the following after the first
sentence thereof:

     "Notwithstanding anything to the contrary in this Lease, including
     without limitation, Section 21.02, or in any other Basic Document:  From
     and after September 27, 2000 through the L/C Release Date (as defined
     below), the amount available to be drawn under the Rent Letter of Credit
     (and each successor thereto or replacement thereof) shall equal (but in
     no event be less than) the then applicable annual Basic Rent amount due
     on the next Basic Rent Payment Date.  As of each Basic Rent Payment
     Date, to the extent the amount of the Rent Letter of Credit outstanding
     on such Basic Rent Payment Date exceeds the amount of the Rent Letter of
     Credit required by the preceding sentence (provided that the Basic Rent
     payment then due has been paid) , the Lessee may, at its option, in
     accordance with Section 21.01(b), cause the existing Rent Letter of
     Credit to be replaced with a Rent Letter of Credit in the amount then
     required.  The Lessee's obligation to cause a Rent Letter of Credit to
     be issued in favor of Lessor shall terminate on the L/C Release Date
     (provided that the Basic Rent payment then due has been paid), at which
     time Lessor agrees not to make any drawing under any Rent Letter of
     Credit then outstanding and Lessor shall, as provided in Section
     10.19(b) of the Participation Agreement, surrender such Rent Letter of
     Credit to the issuer thereof for cancellation.  "L/C Release Date" shall
     mean (i) February 28, 2005 (if the Lessee shall not have delivered a
     timely renewal notice pursuant to Section 5.01(b) of this Agreement and
     there shall be no Basic Rent payment then due and owing) or (ii) the
     date that is one year before the end of any Renewal Term (if the Lessee
     shall not have delivered timely renewal notice

<PAGE>
     for an additional Renewal Term pursuant to Section 5.01(b) of this
     Agreement and there shall be no Basic Rent payment then due and owing)."
