EXHIBIT 10.11


                      AMENDMENT TO VISKASE COMPANIES, INC.
                       PARALLEL NONQUALIFIED SAVINGS PLAN

         The Viskase Companies, Inc. Parallel Nonqualified Savings Plan (the
"Plan") was originally established by Viskase Companies, Inc. (the "Company"),
under its prior name of Envirodyne Industries, Inc., effective January 1, 1987.
The Plan permits certain key executives of the Company to elect to defer a
portion of their compensation, and to receive additional employer contributions,
in excess of the amounts permitted under the Company's tax qualified retirement
plan.

         Each executive who participates in the Plan has an Employee
Contribution Account and a Supplemental Benefit Account, to which amounts of
deferred compensation and additional employer contributions, respectively, are
credited. Under the current terms of the Plan, each such account is credited
with earnings at the rates specified under the Plan.

         Pursuant to a resolution adopted by the Board of Directors of the
Company and approved by the stockholders at the annual meeting held July 29,
1999, participants in the Plan shall be permitted to have the return on a
portion of their Plan accounts determined as if such portion had been invested
in the Common Stock of the Company, in lieu of being credited with earnings at
the rate provided in the Plan. In addition, the resolution authorized the
creation of the Viskase Stock Fund, in the form of a grantor trust of the type
commonly known as a "rabbi trust", to which the Company will issue up to
1,000,000 shares of Common Stock, which will be used to measure the return on
the portion of accounts deemed to be invested in Common Stock, and as a source
of distributions to participants upon their termination of employment.

         In order to reflect the foregoing, and in accordance with the authority
reserved by the Board of Directors pursuant to Section 5.01 of the Plan, the
Plan is hereby amended as follows:

         1. Article I of the Plan is amended by inserting the following
definition immediately following the definition of "Plan Year":

         "STOCK FUND means the Viskase Stock Fund established pursuant to
Section 5.05A."

         2. Section 3.03 is amended by the addition of a new subsection (c) to
read as follows:

         "(c) In lieu of the provisions of subsections (a) and (b), a
         Participant may elect, subject to the limitations set forth below, to
         have all or a portion of his Supplemental Benefit Account of his
         Employee Contribution Account, or both, adjusted to reflect the
         earnings, gains, and losses that would have been credited or debited
         thereto had such portion been invested in the Stock Fund. If a
         Participant so elects, a separate subaccount of his Supplemental
         Benefit Account or Employee Contribution Account, or both, shall be
         established, which shall be credited with the portion of the
         Participant's accounts specified by the Participant, and shall
         thereafter be credited with the percentage elected by the Participant
         of all new contributions pursuant to Section 3.02. Amounts credited to
         such subaccount shall be treated as invested in Common Stock of the
         Company at the fair market value of such Common Stock on the date
         credited to the subaccount, and thereafter shall be adjusted as if
         actually invested in such number of shares of Common Stock.




         Participants may also be permitted to transfer amounts into and out of
         such subaccounts from time to time. The Committee shall establish
         rules, procedures and limitations governing the treatment of the
         portion of Participants' accounts deemed to be invested in the Stock
         Fund, which may limit or restrict the ability of Participants to change
         elections and to transfer amounts into and out of the Stock Fund;
         provided, however, that in no event shall the aggregate portion of all
         Participants' accounts deemed to be invested in the Stock Fund exceed
         the amount of Common Stock actually authorized for issuance the Stock
         Fund pursuant to Section 5.05A (and any excess amount, allocated among
         all Participants in the manner prescribed by the Committee, shall be
         subject to subsections (a) and (b)); and provided further, that in no
         event shall any Participants' election be applied retroactively to
         effect the adjustment of his account prior to the date that such
         election is received by the Company."

         3. A new Section 3.07 is added following Section 3.06, to read as
follows:

         "3.07    DISTRIBUTION OF STOCK

         To the extent that a portion of the Participant's Supplemental Benefit
         Account or Employee Contribution Account, or both, is allocated to a
         subaccount treated as invested in the Stock Fund pursuant to Section
         3.03(c) at the time a distribution is to be made pursuant to either
         Section 3.05 or 3.06, there shall be distributed to such Participant or
         his Beneficiary, unless the Committee otherwise determines, a number of
         shares of Common Stock equal to the number of whole shares deemed to be
         held in such subaccount or subaccounts, and cash equal to any
         fractional shares."

         4. A new Section 5.05A is added following Section 5.05, to read as
follows:

         "5.05A   STOCK FUND

         The Company, as grantor, shall establish a grantor trust of the type
         commonly known as a "rabbi trust", which shall be known as the Viskase
         Stock Fund (the "Stock Fund"). The Company shall appoint a trustee of
         the Stock Fund, and shall have the authority to remove and replace the
         trustee from time to time, and to enter into a trust agreement with
         such trustee and amend such agreement from time to time, all on such
         terms as the Committee shall determine. The Company shall transfer
         shares of Common Stock to the Stock Fund at such time as Participants
         elect to have a portion of their accounts adjusted as if they were
         invested in the Stock Fund pursuant to Section 3.03(c). All dividends
         paid on stock held in the Stock Fund shall be reinvested in Common
         Stock. If at any time a distribution of Common Stock is to be made to a
         Participant or his Beneficiary pursuant to Section 3.07, such Common
         Stock may be distributed out of the Stock Fund, which shall satisfy the
         Company's obligation pursuant to Section 3.07 to the extent of such
         distribution. In the event the Company elects to distribute shares of
         Common Stock directly to such Participant or Beneficiary, or to
         distribute cash in lieu of shares of Common Stock (other than in lieu
         of fractional shares), the same number of shares shall be returned from
         the Stock Fund to the Company. In no event shall the Company be
         obligated to transfer more than 1,000,000 shares (adjusted
         appropriately by the Committee in the event of any recapitalization,
         stock split, stock dividend, or similar transaction) to





         the Stock Fund, reduced by any shares returned as described in the
         preceding sentence. Anything else contained herein to the contrary
         notwithstanding, the Stock Fund shall be subject to the provisions of
         Section 5.05. The Company shall be the owner of the shares of Common
         Stock held in the Stock Fund (which shall be subject to the claims of
         the Company's creditors), and any voting rights shall be exercised by
         the trustee, subject to the direction of the Company to the extent
         provided by the trust agreement. The failure of the Company to
         establish the Stock Fund or to transfer shares of Common Stock to it
         shall not affect the obligations of the Company under this Plan and, in
         the absence of the Stock Fund, the accounts of Participants who elect
         to have their accounts adjusted as provided under Section 3.03(c) shall
         be adjusted as if the Stock Fund had been established, as determined by
         the Committee on an equitable basis."

         5. The provisions of this amendment are effective July 29, 1999. Except
as otherwise specifically provided herein, all provisions of the Plan shall
remain in full force and effect.

IN WITNESS WHEREOF, the Company has caused this Amendment to be executed as of
July 29, 1999.
