No member of the Committee shall be liable for any action, omission, or determination relating to the Plan, and Viskase shall indemnify and hold harmless each member of the Committee and each other director or employee of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been delegated against any cost or expense (including counsel fees) or liability (including any sum paid in settlement of a claim with the approval of the Committee) arising out of any action, omission or determination relating to the Plan, unless, in any case, such action, omission or determination was taken or made by such member, director or employee in bad faith and without reasonable belief that it was in the best interests of the Company.

4.                                      ELIGIBILITY

The persons who shall be eligible to receive Performance Awards pursuant to the Plan shall be members of management of the Company who are largely responsible for the management, growth and protection of the business of the Company as the Committee shall select from time to time.

(a)               Grant of Performance Awards.

Subject to the terms of the Plan, Performance Awards may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as the Committee determines in its sole and absolute discretion.

4

(b)               Value of Performance Awards.

Each Performance Award may have an initial value established by the Committee at the time of grant.  The Committee will set performance objectives in its discretion which, depending on the extent to which they are met, will determine the value of the Performance Awards that will be paid out to the Participant.  For purposes of this Section 5, the time period during which the performance objectives must be met will be called the “Performance Period” and will be set by the Committee in its sole and absolute discretion.

(c)                Earning of Performance Awards.

Subject to the terms and conditions of this Plan and the applicable Award Agreement, after the Performance Period has ended, the holder of Performance Award will be entitled to receive payout of the value of the Performance Award earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives have been achieved.

(d)               Award Agreement.

Each grant of Performance Awards will be evidenced by a separate Award Agreement specifying the material terms and conditions of the Performance Award and such other provisions as the Committee determines in its sole and absolute discretion.

(e)                Form and Timing of Payment of Performance Awards.

As soon as practicable after the close of the Performance Period, the Chief Financial Officer of the Company shall calculate the financial performance and the proposed payout under the Plan based on the achievement of the financial performance measures.  The proposed payout shall be presented to the Committee for review and approval.  Once approved, payment of the award shall be made within 30 days after completion of the annual audit but not later than June 30 of the calendar year following the end of the Performance Period during which the award is earned.  The Committee will pay earned Performance Awards in the form of cash as specified in the Award Agreement.

(f)                 Payment in the Event of Death, Disability, or a Separation from Service due to (i) Retirement, (ii) Termination by the Company without Cause, or (iii) Termination by the Company due to Participant’s Disability as Defined in the Participant’s Agreement.

In the event of a Participant’s death, Disability, or Separation from Service due to (i) Retirement, (ii) termination by the Company without Cause, or (iii) termination by the Company due to the Participant’s Disability, the Participant will forfeit all Performance Awards to the Company, unless otherwise determined by the Committee in its sole and absolute discretion or as set forth in the Participant’s Award Agreement.  Payment of earned Performance Awards, if any, will be made at a time specified by the Committee in its sole and absolute discretion or as set forth in the Participant’s Award Agreement or as provided in 26 C.F.R. 1.409A-3(j)(2).

(g)                Payment in the Event of a Separation from Service for Other Reasons.

If a Participant incurs a Separation from Service during the Performance Period for any reason other than (i) Retirement, (ii) termination by the Company without Cause, or (iii) termination by the Company due to the Participant’s Disability, the Participant will forfeit all

5

Performance Awards to the Company, unless otherwise determined by the Committee in its sole and absolute discretion or as set forth in the Participant’s Award Agreement.

(h)               Payment Upon a Change in Control.

Notwithstanding anything to the contrary in this Section 5, upon the occurrence of a Change in Control during the Performance Period, the Participant shall be entitled to receive a Performance Award payout calculated in the manner specified in the applicable Performance Award Agreement.

(i)                   Leaves of Absence.

Subject to all applicable law, the Committee may, in its sole and absolute discretion, adjust any award, on a pro-rata basis, for any leave of absence taken by the Participant during the Performance Period.

(j)                  Nontransferability.

Except as otherwise provided in a Participant’s Award Agreement, Performance Awards may not be sold, transferred, pledged, assigned or otherwise alienated or  hypothecated, other than by will or by the laws of descent and distribution, or pursuant to a domestic relations order (as defined in Code Section 414(p)).

6.                                      ADJUSTMENTS

In the event of a significant corporate transaction or event, the Committee reserves the right to make such adjustments as are necessary to preserve the original intent of the Performance Award and the goals contained herein, including, but not limited to, the replacement of the Performance Award with a similar award or the acceleration of payments to the extent permissible under Code Section 409A.  In addition, the Committee may, at any time prior to the final determination of Performance Awards, increase, decrease or otherwise adjust performance measures and targets as a result of extraordinary or non-recurring events, changes in applicable accounting rules or principles, changes in the Company’s methods of accounting, changes in applicable law, changes due to any consolidation, acquisition or reorganization affecting the Company or such other material change in the Company’s business.  Any adjustment pursuant to this Section 6 shall be consistent with the applicable event and in such manner as the Committee may, in its sole and absolute discretion, deem appropriate and equitable to prevent substantial dilution or enlargement of the rights granted to, or available for, Participants under the Plan. Any such adjustment determined by the Committee shall be final, binding and conclusive on the Company and all Participants and their respective heirs, executors, administrators, successors and permitted assigns.  Except as expressly provided in this Section 6 or in the applicable Award Agreement, a Participant shall have no rights by reason of any Section 6 event.

7.                                      NO SPECIAL EMPLOYMENT RIGHTS; NO RIGHT TO PERFORMANCE AWARD

Nothing contained in the Plan or any Performance Award shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or interfere in any way with the right of the Company, subject to the terms of any separate employment or other agreement to the contrary, at any time to terminate such employment or to increase or

6

decrease the compensation of the Participant from the rate in existence at the time of the grant of a Performance Award.

No person shall have any claim or right to receive a Performance Award hereunder, and the Committee’s granting of a Performance Award to a Participant at any time shall neither require the Committee to grant a Performance Award to such Participant or any other Participant or other person at any other time nor preclude the Committee from making subsequent grants to such Participant or any other Participant or other person.

8.                                      COMPLIANCE WITH CODE SECTION 409A

The Plan and Performance Awards, and all amounts payable with respect to Performance Awards, are intended to comply with, or be exempt from, Code Section 409A and the interpretative guidance thereunder and shall be construed, interpreted and administered accordingly.  If an unintentional operational failure occurs with respect to Code Section 409A, any affected Participant or beneficiary shall fully cooperate with the Company to correct the failure to the extent possible in accordance with any correction procedure established by the U.S. Department of the Treasury.  If a Participant is a “specified employee” (as such term is defined for purposes of Code Section 409A) at the time of his or her termination of employment, no amount that is subject to Code Section 409A and that becomes payable by reason of such termination of employment shall be paid to the Participant before the earlier of (i) the expiration of the six-month period measured from the date of the Participant’s termination of employment, and (ii) the date of the Participant’s death.  A termination of employment shall be deemed to occur only if it is a Separation from Service within the meaning of Code Section 409A, and references in the Plan and any Award Agreement to “termination,” “termination of employment,” or like terms shall mean a Separation from Service.  In no event whatsoever shall the Company or its affiliates be liable for any additional tax, interest or penalty that may be imposed on any Participant pursuant to Code Section 409A or any damages for failing to comply with Code Section 409A.

9.                                      CANCELLATION, RESCISSION, AND CLAWBACK OF PERFORMANCE AWARDS

The Committee shall provide in each Award Agreement that, in the event of a restatement of the Company’s consolidated financial statements that would reduce the amount of any previously awarded Performance Awards, the related outstanding Performance Awards will be cancelled or reduced accordingly, and the Participant shall pay over to the Company an amount equal to any gain realized as a result of the exercise, distribution or settlement (whether at the time of exercise, distribution or settlement or thereafter) within (a) the twenty-four (24) months preceding such financial restatement for the Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer of the Company or (b) the twelve (12) months preceding such financial restatement for all other Participants.

Additionally, the Committee may at any time, in its sole and absolute discretion, cancel, declare forfeited, rescind, or require the return of any outstanding Performance Award (or a portion thereof) upon the Committee determining that the Participant has, at any time (whether before or after the grant date of the Performance Award), committed a Breach of Conduct.  In addition, at any time following the payment of a Performance Award, the Committee may, in its sole and absolute discretion, rescind any such payment and require the repayment of a Performance Award (or a portion thereof) upon the Committee determining that the Participant has, at any time (whether before or after the payment of the Performance Award), committed a Breach of Conduct.

7

The Committee’s determination that a Participant has committed a Breach of Conduct, and its decision to require rescission of a Performance Award’s payment, shall be conclusive, binding, and final on all parties.  The Committee’s determination that a Participant has violated the terms or conditions of the Plan or the Performance Award and the Committee’s decision to cancel, declare forfeited, or rescind a Performance Award or to require rescission of a Performance Award’s payment shall be conclusive, binding, and final on all parties.

In connection with any cancellation, forfeiture or rescission contemplated by this Section 9, the terms of repayment by the applicable Participant shall be determined in the Committee’s sole and absolute discretion, which may include, among other terms, the repayment being required to be made (i) in one or more installments or payroll deductions or deducted from future bonus payments or (ii) immediately in a lump sum in the event that such Participant incurs a termination of employment.

10.                               WITHHOLDING TAXES

The Company shall have the right to withhold from any payments distributable to the Participant hereunder the amount of any withholding or other tax due with respect to such payment prior to the delivery of such cash or property to the Participant.

11.                               AMENDMENT OF THE PLAN AND OUTSTANDING AWARD AGREEMENTS

The Board of Directors or Committee may at any time suspend or discontinue the Plan or revise or amend the Plan or any outstanding Performance Award in any respect whatsoever; provided, however, that no such suspension, discontinuance, revision or amendment shall adversely impair the rights of any Participant pursuant to an outstanding Performance Award without the consent of such Participant.  Notwithstanding the foregoing, the Board of Directors or Committee may take such actions as it deems appropriate to ensure that the Plan and any Performance Awards may comply with any tax, securities or other applicable law.  Nothing herein shall restrict the Board of Directors’ or Committee’s ability to exercise its discretionary authority as provided in the Plan.

12.                               TRANSFERS UPON DEATH

Upon the death of a Participant, outstanding Performance Awards granted to such Participant may be transferred only to the executors or administrators of the Participant’s estate or to any person or persons who shall have acquired such right by will or by the laws of descent and distribution.  No transfer by will or the laws of descent and distribution of any Performance Award shall be effective to bind Viskase unless the Committee shall have been furnished with (a) written notice thereof and with a copy of the will and/or such evidence as the Committee may deem necessary to establish the validity of the transfer and (b) an agreement by the transferee to comply with all the terms and conditions of the Performance Award that are or would have been applicable to the Participant and to be bound by the acknowledgments made by the Participant in connection with the grant of the Performance Award.

13.                               FAILURE TO COMPLY

In addition to the remedies of Viskase elsewhere provided for herein, failure by a Participant to comply with any of the terms and conditions of the Plan or the agreement executed

8

by such Participant evidencing a Performance Award, unless such failure is remedied by such Participant within ten days after having been notified of such failure by the Committee, shall be grounds for the cancellation and forfeiture of such Performance Award, in whole or in part, as the Committee, in its absolute discretion, may determine.

14.                               EFFECTIVE DATE AND TERM OF PLAN

The Plan was originally adopted on June 15, 2012 by the Board of Directors.  The Plan was amended on March 10, 2017 by the Committee.  The Committee or Board of Directors may terminate the plan at any time subject to the provisions of Section 11 of this Plan.

15.                               GOVERNING LAW.

The Plan is governed by the laws of the State of New York and as such will be construed under and in accordance with the laws of the State of New York without regard to conflicts of law.

16.                               FUNDED STATUS.

Nothing in the Plan will require the Company to segregate or set aside any funds or other property for the purpose of paying any portion of a Performance Award. No Participant, beneficiary or other person will have any right, title or interest in any amount awarded under the Plan prior to the payment of such Performance Award to him or her or the close of any Performance Period, or in any property of the Company or its affiliates. A Participant’s rights to a Performance Award under the Plan are no greater than those of unsecured general creditors of the Company.
