4.2 Experience. The Investor is experienced in evaluating and investing in private placement transactions of securities of companies such as the Company, and has either individually or through its current officers, directors or partners such knowledge and experience in financial and business matters that the Investor is capable of evaluating the merits and risks of the Investor’s prospective investment in the Company, and has the ability to bear the economic risks of the investment.

4.3 Accredited Investor. The Investor is an “accredited investor” within the meaning of Securities and Exchange Commission Rule 501 of Regulation D, as presently in effect, under the Securities Act.

4.4 Purchase Entirely for Own Account. This Agreement is made with the Investor in reliance upon its representation to the Company, which by the Investor’s execution of this Agreement the Investor hereby confirms, that the Purchased Shares and Option Shares, if applicable, will be acquired for investment for its own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Investor has no present intention of selling, granting any participation in, or otherwise distributing the same.

4.6 No Public Market. The Investor understands that no public market now exists for the Series A Preferred Stock, and the Company has made no assurances that a public market will ever exist for the Series A Preferred Stock and that it is unlikely that a public market will ever exist for the Series A Preferred Stock.

The Investor acknowledges that, to the extent applicable, each certificate evidencing the Shares, the Option Shares and the Common Stock issuable upon conversion of the Shares shall be endorsed with the legend substantially in the form set forth below, as well as any additional legend imposed or required by applicable state securities laws:

THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT, OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

The Company agrees that, subject to limitations under applicable law, the proceeds of the Rights Offering will be used exclusively to redeem Shares then held by the Investors on a pro rata basis. All consideration proposed to be paid by the Investors for any Common Stock subscribed for by the Investors under the terms of Rights received as part of the Rights Offering may be paid in Shares valued at their liquidation value plus accrued and unpaid dividends thereon. The Investors agree on behalf of themselves and their respective affiliates that own Common Stock (“Investor Rights Holders”) that, with respect to the Rights Offering, if the aggregate cash consideration paid to the Company by all holders of Rights (other than the Investor Rights Holders) in connection with the subscription for Common Stock under the Rights is equal to or greater than Ten Million Dollars ($10,000,000), then the Investor Rights Holders shall be deemed to have subscribed for, without any further action on the part of the Company or the Investor Rights Holders, a number of shares of Common Stock equal to (a) the total number of shares of Common Stock the Investor Rights Holders have the right to subscribe for under the Rights multiplied by (b) (i) the total number of shares of Common Stock subscribed for under the Rights Offering by all holders of Rights (other than the Investor Rights Holders) divided by (ii) the total number of shares of Common Stock available to be subscribed for by all holders of Rights (other than the Investor Rights Holders). The Investors acknowledge that they shall not be entitled to receive Rights in respect of the Shares purchased hereunder.

8.3 Defense of Third Party Claims. If any legal proceedings shall be instituted or any claim is asserted by any third party in respect of which any party hereto may have an obligation

to indemnify another party, the party asserting such right to indemnity (the “Indemnified Party”) shall give the party from whom indemnity is sought (the “Indemnifying Party”) written notice thereof, but any failure to so notify the Indemnifying Party shall not relieve it from any liability that it may have to the Indemnified Party, other than to the extent the Indemnifying Party is actually prejudiced thereby. Such written notice shall describe in reasonable detail the facts constituting the basis for such third-party claim and the amount of the potential Loss, in each case, to the extent known. The Indemnifying Party shall have the right, at its option and expense, to participate in the defense of such proceeding or claim, but not to control the defense, negotiation or settlement thereof, which control shall at all times rest with the Indemnified Party, unless the Indemnifying Party (a) notifies the Indemnified Party of such defense in writing within thirty days after the Indemnified Party has given notice of the third party claim, (b) furnishes satisfactory evidence of its financial ability to indemnify the Indemnified Party, and (c) conducts the defense of the third party claim actively and diligently; in which case, the Indemnifying Party may assume such control at its expense through counsel reasonably satisfactory to such Indemnified Party; provided, however, that: (w) the Indemnified Party shall be entitled to participate in the defense of such claim and to employ counsel at its own expense to assist in the handling of such claim; (x) the Indemnifying Party shall obtain the prior written approval of the Indemnified Party before entering into any settlement of such claim or ceasing to defend against such claim (with such approval not to be unreasonably withheld); (y) no Indemnifying Party shall consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Indemnified Party of a release from all liability in respect of such claim; and (z) the Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and the Indemnified Party shall be entitled to have sole control over, the defense or settlement of any claim to the extent the claim seeks an order, injunction, non-monetary or other equitable relief against the Indemnified Party which, if successful, could materially interfere with the business, operations, assets, condition (financial or otherwise) or prospects of the Indemnified Party.

After written notice by the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of any such action, the Indemnifying Party shall not be liable to such Indemnified Party hereunder for any legal expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. If the Indemnifying Party does not assume control of the defense of such claim as provided in this Section 8.3, the Indemnified Party shall have the right to defend such claim in such manner as it may deem appropriate at the cost and expense of the Indemnifying Party, and the Indemnifying Party will promptly reimburse the Indemnified Party therefor in accordance with this Section 8.3. The reimbursement of fees, costs and expenses required by this Section 8.3 shall be made by periodic payments during the course of the investigations or defense, as and when bills are received or expenses incurred.

8.4 Other Claims.

Exhibit D

Rights Offering Term Sheet

This Memorandum of Terms summarizes the principal terms of the proposed offering (the “Rights Offering”) by Viskase Companies, Inc. (the “Company”) of subscription rights (the “Subscription Rights”) to purchase shares of common stock, par value $0.01 per share (the “Common Stock”), of the Company, for the purpose of redeeming outstanding shares of Series A Convertible Preferred Stock, par value $0.01 per share, of the Company (the “Series A Preferred Stock”). The Series A Preferred Stock has been sold by the Company to certain investors pursuant to the Series A Preferred Stock Purchase Agreement, dated November 7, 2006 (the “Stock Purchase Agreement”)

Number of Rights:

An aggregate of 12,307,692 Rights will be issued on a ratable basis in respect of the issued and outstanding shares of Common Stock at the time of the commencement of the Rights Offering.

Exercise Price:

Each Subscription Right shall entitle the holder thereof (a “Holder”) to subscribe for shares of Common Stock at a ratio of one (1) share of Common Stock per Subscription Right (the “Rights Conversion Ratio”), subject to adjustment as set forth below. The exercise price per Subscription Right (the “Exercise Price”) shall be equal to $1.95 per share of the Common Stock. The Subscription Rights will be exercisable for an aggregate exercise price of $24 million.

Adjustments:

If a stock dividend or other distribution, recapitalization, forward or reverse stock split, subdivision, consolidation or reduction of capital, reorganization, merger, consolidation, scheme or arrangement, split-up, spin-off or combination, or similar transaction or event affects the number of shares of Common Stock issuable upon exercise of the Subscription Rights (shares of Common Stock issuable upon the exercise of all Subscription Rights, the “Registrable Shares”), the Company will make an equitable change or adjustment as it deems appropriate in the number and kind of securities subject to or to be issued in connection with the exercise of the Subscription Rights and the Exercise Price of the Subscription Rights. No fractional shares of Common Stock will be issued upon the exercise of Subscription Rights. When any exercise of Subscription Rights would result in the issuance of a number of shares of Common Stock that is not a whole number, the actual number of shares will be rounded down to the next lower whole number with no further payment or other distribution therefor.

Offering Period:

The Subscription Rights (and related oversubscription rights) shall become exercisable on the effective date of the registration statement for the registration of Registrable Shares (the “Commencement Date”) and shall expire at 5:00 p.m. New York City time within sixty (60) calendar days after the Commencement Date (the “Expiration Time”) but in no event shall the Expiration Time occur more than one hundred eighty (180) calendar days from the Closing (as defined in the Stock Purchase Agreement). Prior to the expiration of such period, any Holder desiring to participate in the Rights Offering must exercise all or any portion of its Subscription Rights (and related oversubscription rights, if desired). Any exercise of Subscription Rights (and related oversubscription rights) will be irrevocable. At the Expiration Time, unexercised Subscription Rights shall terminate and be null and void and the Company shall not be obligated to honor any such purported exercise received by the Company or its designee after the Expiration Time, regardless of when the documents relating to such exercise were sent.

Transferability:

The Subscription Rights are at all times transferable but, prior to the Commencement Date, shall not be exercisable.

Exercise Procedures:

In order to exercise Subscription Rights, each Holder must: (a) return a duly completed subscription form (the “Subscription Form”) to the Company or its designee so that such form is actually received by the Company or its designee on or before the Expiration Time; and (b) pay to the Company or its designee on or before the Expiration Time the aggregate Exercise Price for all of the Company Common Stock purchased pursuant to the Holder’s exercise of the Subscription Rights in accordance with the wire instructions set forth on the Subscription Form or by bank or cashier’s check or certificates representing Series A Preferred Stock delivered to the Company or its designee along with the Subscription Form. If, on or prior to the Expiration Time, the Company or its designee for any reason does not receive a duly completed Subscription Form and immediately available funds in an amount equal to the aggregate Exercise Price, the Subscription Rights shall be deemed to have been unexercised and to terminate and be null and void. The Company shall adopt such detailed procedures as is necessary to efficiently administer the exercise of the Subscription Rights and shall prepare documents that reflect the terms herein and such other terms as the Company shall determine to be appropriate in the implementation hereof.

Incidents of Ownership:

The Subscription Rights shall have no rights, powers or privileges other than as expressly set forth herein, and in particular, the Subscription Rights shall have no voting rights, dividend rights, conversion rights, preemption rights, liquidation rights or other rights of a stockholder.

Use of Proceeds:

Upon the exercise of Subscription Rights, all proceeds thereof shall be applied to the redemption of the Series A Preferred Stock.

Administration:

All questions concerning the timeliness, viability, form and eligibility of any exercise of Subscription Rights shall be determined by the Company whose determination shall be final and binding. The Company may waive in its sole discretion any defect or irregularity, or permit a defect or irregularity to be corrected within such times as it may determine, or reject the purported exercise of any Subscription Rights that the Company has determined to have failed to comply with the applicable requirements.

Extension/Termination:

The Company shall have the option of extending the period of the Rights Offering, at its sole discretion; provided that, in no event shall the Expiration Time occur more than one hundred eighty (180) calendar days from the Closing (as defined in the Stock Purchase Agreement). The Company shall also have the right to withdraw or terminate the Rights Offering at any time and for any reason. In the event the Rights Offering is withdrawn or terminated, all funds received from subscriptions will be returned (without interest), except to the extent Common Stock has already been issued in respect of any such subscriptions.
