remedies not inconsistent herewith as provided under the Code, by law, or in
equity. No exercise by the Collateral Agent of one right or remedy shall be
deemed an election, and no waiver by the Collateral Agent of any Event of
Default shall be deemed a continuing waiver. No delay by the Collateral Agent
shall constitute a waiver, election, or acquiescence by it.

7. TAXES AND EXPENSES.

            If any Debtor fails to pay any monies (whether taxes, assessments,
rents, insurance premiums, or, in the case of leased properties or assets, rents
or other amounts payable under such leases) due to third Persons, or fails to
make any deposits or furnish any required proof of payment or deposit, in each
case, to the extent required under the terms of this Agreement, then, the

constitute Obligations owing to the Collateral Agent and any such payments shall

deposits in the future or a waiver by the Collateral Agent of any Event of
Default under this Agreement. The Collateral Agent need not inquire as to, or
contest the validity of, any such expense, tax, or Lien and the receipt of the
usual official notice for the payment thereof shall be conclusive evidence that
the same was validly due and owing.

making such payment is entitled to be indemnified and reimbursed by such Debtor
with respect thereto. WITHOUT LIMITATION, THE FOREGOING INDEMNITY SHALL APPLY TO

the Collateral Agent's rights thereafter to require strict performance by each

      12.2 SUCCESSORS. This Agreement shall bind and inure to the benefit of the
respective successors and assigns of each of the parties; provided, however,
that no party may assign this Agreement or any rights or duties hereunder other
than pursuant to the terms of the Indenture.

convenience only. Unless the contrary is compelled by the context, everything
contained in each Section applies equally to this entire Agreement.

      12.4 INTERPRETATION; GOVERNMENT REGULATION. Neither this Agreement nor any

      12.7 REVIVAL AND REINSTATEMENT OF OBLIGATIONS. If the incurrence or
payment of the Obligations by any Debtor or the transfer by any Debtor to the
Collateral Agent of any property of such Debtor should for any reason
subsequently be declared to be void or voidable under any state or federal law
relating to creditors' rights, including provisions of the Bankruptcy Code
relating to fraudulent conveyances, preferences, or other voidable or
recoverable payments of money or transfers of property (collectively, a
"Voidable Transfer"), and if the Collateral Agent is required to repay or
restore, in whole or in part, any such Voidable Transfer, or elects to do so

                                       20
<PAGE>

upon the reasonable advice of its counsel, then, as to any such Voidable
Transfer, or the amount thereof that the Collateral Agent is required or elects
to repay or restore, and as to all reasonable costs, expenses, and attorneys
fees of the Collateral Agent related thereto, the liability of such Debtor
automatically shall be revived, reinstated, and restored and shall exist as
though such Voidable Transfer had never been made.

      12.8 INTEGRATION. This Agreement, together with the other Indenture
Documents, reflects the entire understanding of the parties with respect to the
transactions contemplated hereby and shall not be contradicted or qualified by
any other agreement, oral or written, before the date hereof.

      12.9 DEBTORS REMAIN LIABLE. Anything herein to the contrary
notwithstanding:

            (a) Debtors will remain liable under the contracts and agreements
      included in the Collateral to the extent set forth therein, and will
      perform all of their duties and obligations under such contracts and
      agreements to the same extent as if this Agreement had not been executed;

            (b) the exercise by Collateral Agent of any of its rights hereunder
      will not release any Debtor from any of its duties or obligations under
      any such contracts or agreements included in the Collateral; and

            (a) none of Collateral Agent, the Trustee or any Holder will have
any obligation or liability under any contracts or agreements included in the
Collateral by reason of this Agreement, nor will any such Person be obligated to
perform any of the obligations or duties of any Debtor thereunder or to take any
action to collect or enforce any claim for payment assigned hereunder.

      12.10 COLLATERAL COMPRISED OF EQUITY INTERESTS OF SUBSIDIARIES. The
provisions of the Pledge Agreement, as they relate to Collateral comprised of
Equity Interests of Issuers that are Subsidiaries of any Debtor and the Excluded
Capital Stock related thereto are incorporated by reference herein, mutatis
mutandis.

      12.11 CONTINUING SECURITY INTEREST. This Agreement shall create a
continuing security interest in the Collateral and shall: (i) remain in full
force and effect until the payment in full of all Obligations (other than
contingent indemnification obligations) or the Defeasance thereof except as
otherwise provided in the Indenture; (ii) be binding upon each Debtor and its
successors and assigns, except as otherwise provided in the Indenture; and (iii)
inure to the benefit of Collateral Agent and its successors, transferees, and
assigns. Upon the payment in full of all Obligations (other than contingent
indemnification obligations) or the Defeasance thereof, the security interests
granted herein shall automatically terminate and all rights to the Collateral
shall revert to the applicable Debtor and all restrictions imposed on the
exercise by such Debtor of any of its rights with respect to any Excluded
Capital Stock held by it shall be terminated. Upon any termination of any
security interest referred to in this Section 12.11, Collateral Agent will, at
Debtors' expense, execute and deliver to each Debtor such documents without
recourse, representation or warranty as such Debtor shall reasonably request to
evidence such termination.

                                       21
<PAGE>

      12.12 SECURITY INTEREST ABSOLUTE. To the maximum extent permitted by law,
all rights of Collateral Agent, all security interests hereunder, and all
obligations of each Debtor hereunder, shall be absolute and unconditional
irrespective of:

            (a) any lack of validity or enforceability of any of the Obligations
or any other agreement or instrument relating thereto, including any of the
Indenture Documents;

            (b) any change in the time, manner, or place of payment of, or in
any other term of, all or any of the Obligations, or any other amendment or
waiver of or any consent to any departure from any of the Indenture Documents,
or any other agreement or instrument relating thereto;

            (c) any exchange, release, or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to departure
from any guaranty for all or any of the Obligations; or

            (d) any other circumstances that might otherwise constitute a
defense available to, or a discharge of, any Debtor.

To the maximum extent permitted by law, each Debtor hereby waives any right to
require Collateral Agent to: (A) proceed against or exhaust any security held
from such Debtor; or (B) pursue any other remedy in Collateral Agent's power
whatsoever.

      12.13 POSTPONEMENT OF SUBROGATION. Each Debtor hereby agrees that it will
not exercise any rights which it may acquire by reason of any payment made
hereunder, whether by way of subrogation, reimbursement or otherwise, until the
prior payment in full of all Obligations (other than contingent indemnification
obligations) or the Defeasance thereof. Subject to the terms of the
Intercreditor Agreement, any amount paid to any Debtor on account of any payment
made hereunder prior to the payment in full of all Obligations (other than
contingent indemnification obligations) or the Defeasance thereof shall be held
in trust for the benefit of Collateral Agent, the Holders and the Trustee and
shall immediately be paid to Collateral Agent, to be distributed to the Trustee
for application against the Obligations, whether matured or unmatured, in
accordance with the terms of the Indenture. In furtherance of the foregoing, for
so long as any Obligations (other than contingent indemnification obligations)
remain outstanding or the Defeasance thereof shall not have been consummated,
each Debtor shall refrain from taking any action or commencing any proceeding
against Company or any other Debtor (or any of their respective successors or
assigns, whether in connection with a Insolvency Proceeding or otherwise) to
recover any amounts in respect of payments made under this Agreement to
Collateral Agent, the Trustee or any Holder.

      12.14 INTERCREDITOR AGREEMENT.

            (a) The Liens granted hereunder in favor of Collateral Agent for the
benefit of itself, the Trustee and the Holders in respect of the Collateral and
the exercise of any right related thereto thereby shall be subject, in each
case, to the terms of the Intercreditor Agreement.

                                       22
<PAGE>

            (b) In the event of any direct conflict between the express terms
and provisions of this Agreement and of the Intercreditor Agreement, the terms
and provisions of the Intercreditor Agreement shall control.

            (c) Notwithstanding anything to the contrary herein, any provision
hereof that requires any Debtor to (i) deliver any Collateral to Collateral
Agent or (ii) provide that the Collateral Agent have control over such
Collateral may be satisfied by (A) the delivery of such Collateral by such
Debtor to the Administrative Agent for the benefit of the Lenders and Collateral
Agent for the benefit of itself, the Trustee and the Holders pursuant to Section
3.03 of the Intercreditor Agreement and (B) providing that the Administrative
Agent be provided with control with respect to such Collateral of such Debtor
for the benefit of the Lenders and Collateral Agent for the benefit of itself,
the Trustee and the Holders pursuant to Section 3.03 of the Intercreditor
Agreement.

                    INTELLECTUAL PROPERTY SECURITY AGREEMENT

      THIS INTELLECTUAL PROPERTY SECURITY AGREEMENT (this "Agreement"), dated as
of June 29, 2004, is made by VISKASE COMPANIES, INC., a Delaware corporation
(the "Grantor"), in favor of LASALLE BANK NATIONAL ASSOCIATION ("LaSalle"), as
collateral agent (together with its successor(s) thereto in such capacity,
"Grantee") for the Trustee and Holders, in light of the following:

                              W I T N E S S E T H:

      WHEREAS, the Grantor and LaSalle, as collateral agent and as trustee (in
such capacity, the "Trustee"), have entered into an Indenture, dated as of June
29, 2004 (as amended, restated, supplemented or otherwise modified from time to
time, the "Indenture"), pursuant to which the Grantor has issued 90,000 Units
(and, together with any additional units that may be issued from time to time
thereunder or exchanged therefor or for such additional units, the "Units"),
each of which consists of an 11-1/2% Senior Secured Note due 2011 in a principal
amount of $1,000 (and, together with any additional notes that may be issued by
the Grantor from time to time thereunder or exchanged therefor or for such
additional notes, the "Notes") and a warrant to purchase 8.947 shares of common
stock of the Grantor, at an exercise price of $0.01 per share, subject to
adjustment;

      WHEREAS, the Grantor and the Grantee have entered into that certain
Security Agreement, dated as of June 29, 2004 (as amended, restated,
supplemented or otherwise modified from time to time, the "Security Agreement"),
pursuant to which the Grantor has granted security interests in certain of its
assets (including its Intellectual Property) as more fully described therein;

      WHEREAS, the Grantor and Wells Fargo Foothill, Inc. have entered into that
certain Loan and Security Agreement dated as of June 29, 2004 (as amended,
restated, supplemented, replaced or otherwise modified from time to time, the
"Credit Agreement");

      WHEREAS, the Grantee, the Administrative Agent and the Grantor have
entered into that certain Intercreditor and Lien Subordination Agreement, dated
as of June 29, 2004 (as amended, restated, supplemented, replaced or otherwise
modified from time to time, the "Intercreditor Agreement"), which agreement,
among other things, sets forth, as between the Grantee and the Administrative
Agent, the relative priority of their respective Liens in the Collateral
(including the Intellectual Property) and their rights with respect thereto;

      WHEREAS, the Grantor desires to secure its Obligations under the Notes,
the Indenture and each other Indenture Document to which it becomes a party by
granting to Grantee, for the benefit of itself, the Trustee and the Holders,
security interests in the Intellectual Property as set forth herein; and

      WHEREAS, to induce the Initial Purchaser to purchase the Units and the
underlying Notes, each Holder to hold the Units and the underlying Notes to be
held by it and LaSalle to act in its capacities as trustee and collateral agent,
the Grantor desires to pledge, grant, transfer, and assign to Grantee, for the
benefit of itself, the Holders and the Trustee, a security interest in the
Intellectual Property to secure the Obligations, as provided herein.

protect its Trade Secrets from unauthorized or accidental disclosure;

      (v) Grantor is the sole and exclusive owner of the entire and unencumbered
right, title and interest in and to the Registered Intellectual Property, free
and clear of any liens, security

                                     - 3 -
<PAGE>

interests, mortgages, charges and encumbrances, including, without limitation,
licenses, consent-to-use agreements, shop rights and covenants by Grantor not to
sue third Persons (except for Permitted Liens);

      (vi) Grantor has adopted, used and is currently using all of the
Trademarks, and, to the knowledge of Grantor, Grantor's use thereof does not
infringe the intellectual property rights of any person or entity;

      (vii) Grantor has no written notice or knowledge of any suits or actions
commenced or threatened with reference to or in connection with any of the
Intellectual Property;

      (viii) Grantor has the unqualified right to execute and deliver this
Agreement and perform its terms, this Agreement has been executed and delivered
by a duly authorized officer of Grantor, and this Agreement is a legally
enforceable obligation of Grantor;

      (ix) No trademark opposition or cancellation proceedings have been filed
in the prior three years with the United States Patent and Trademark Office
against any of the Trademarks; and

      (x) The Licenses, complete copies of which have been provided to Grantor,
are valid and binding agreements, enforceable in accordance with their terms
(subject, as to the enforcement of remedies, to applicable bankruptcy,
reorganization, insolvency and similar laws from time to time in effect). Each
of the material Licenses is in full force and effect and has not been amended or
abrogated and, to the knowledge of the Grantor, there is no default under any of
the Licenses.

            4. Restrictions on Future Agreements. Except as otherwise permitted
pursuant to the Indenture, Grantor agrees that until all Obligations shall have
been satisfied and paid in full (other than contingent indemnification
obligations) or the Defeasance thereof shall have been consummated, Grantor
shall not, without the prior written consent of Grantee, Dispose, grant a Lien
on, encumber or assign any or all of, or grant any license or sublicense under
(other than as commercially reasonable in Grantor's good faith business
judgment), the Intellectual Property, or enter into any other agreement with
respect to the Intellectual Property, and Grantor further agrees that it shall
not knowingly take any action or knowingly permit any action to be taken by
others subject to its control, including, without limitation, licensees or
sublicensees, or knowingly fail to take any action, which would materially
adversely affect the validity or enforcement of the rights Grantee subject to
this Agreement, other than in the ordinary course of business.

            5. New Intellectual Property. Grantor hereby represents and warrants
to Grantee for the benefit of the Grantee and the other Secured Parties that the
Intellectual Property listed on Exhibits A, B and C, respectively, constitute
all of the Registered Intellectual Property now owned by Grantor. Grantor hereby
represents and warrants to Grantee for the benefit of Grantee and the other
Secured Parties that the Intellectual Property listed on Exhibit C constitute
all of the material Licenses now owned by Grantor. If, before all Obligations
(other than contingent indemnification obligations) shall have been satisfied in
full or the Defeasance thereof shall have been consummated, Grantor shall (i)
become aware of any existing Registered

                                     - 4 -
<PAGE>

Intellectual Property of which Grantor has not previously informed Grantee, (ii)
obtain rights to any Registered Intellectual Property, or (iii) become entitled
to the benefit of any material Intellectual Property which benefit is not in
existence on the date hereof, the provisions of this Agreement above shall
automatically apply thereto and Grantor shall give to Grantee prompt written
notice thereof. Grantor hereby authorizes Grantee to modify this Agreement by
amending Exhibits A, B, C, and D, as applicable, to include any such
Intellectual Property, and Grantee may file or refile this Agreement with the
United States Patent and Trademark Office and United States Copyright Office.
Grantor agrees to execute and deliver any and all documents and instruments
necessary or advisable to record or preserve Grantee's interest in all
Intellectual Property added to Exhibits A, B, C, and D pursuant to this Section.

            6. Royalties; Terms; Rights Upon Default. The term of this Agreement
shall extend until the earlier of (i) the expiration of all of the respective
material Intellectual Property collaterally assigned hereunder, (ii) the payment
in full of all Obligations (other than contingent indemnification obligations)
and (iii) the Defeasance of all Obligations (other than contingent
indemnification obligations) shall have been consummated. Grantor agrees that
upon the occurrence and during the continuance of an Event of Default, the use
by Grantee for the benefit of the Grantee and the other Secured Parties of all
Intellectual Property shall be worldwide and as extensive as the rights of
Grantor to use such Intellectual Property, and without any liability for
royalties or other related charges from Grantee or the other Secured Parties to
Grantor, solely for the purpose of completing production of, advertising for
sale and selling any Intellectual Property.

            7. Grantee's Right to Inspect; Trademark Quality Control. To the
extent permitted by the Security Agreement, Grantee shall have the right, from
time to time with prior notice (unless an Event of Default has occurred and is
continuing, in which case prior notice shall not be required) and, during normal
business hours and prior to payment in full of all Obligations (other than
contingent indemnification obligations) or the Defeasance thereof, to inspect
Grantor's premises and to examine Grantor's books, records and operations,
including, without limitation, Grantor's quality control processes. Grantor
agrees (i) to maintain the quality of any and all products in connection with
which the material Trademarks are used, consistent with the quality of said
products (as determined by Grantor in its commercially reasonable business
judgment) and (ii) to provide Grantee, upon Grantee's reasonable request from
time to time, with a certificate of an officer of Grantor certifying Grantor's
compliance with the foregoing.

            8. Release of Security Interest. Upon the payment and performance in
full in cash of the Obligations (other than contingent indemnification
obligations) or the Defeasance thereof, this Agreement shall terminate, and
Grantee shall execute and deliver such documents and instruments and take such
further action reasonably requested by Grantor, at Grantor's expense, as shall
be necessary to evidence termination of the security interest granted by Grantor
to Grantee for the benefit of the Grantee and the other Secured Parties
hereunder.

            9. Expenses. All costs and expenses incurred in connection with the
performance of any of the agreements set forth herein shall be borne by Grantor.
All fees, costs and expenses, of whatever kind or nature, including reasonable
attorneys' and paralegals' fees and legal expenses, incurred by Grantee (for the
benefit of the Grantee and the other Secured

                                     - 5 -
<PAGE>

Parties) in connection with the filing or recording of any documents (including
all taxes in connection therewith) in public offices, the payment or discharge
of any taxes, counsel fees, maintenance fees, encumbrances or otherwise in
protecting, maintaining or preserving the Intellectual Property, or in defending
or prosecuting any actions or proceedings arising out of or related to the
Intellectual Property, shall be borne by and paid by Grantor on demand by
Grantee on behalf of the Grantee and the other Secured Parties and until so paid
shall bear interest at the "default rate of interest" set forth in the
Indenture.

            10. Duties of Grantor. Grantor shall have the duty to the extent
commercially reasonable and in Grantor's good faith business judgment,
desirable: (i) to file and prosecute diligently any patent, trademark or service
mark applications pending as of the date hereof or hereafter until all
Obligations (other than contingent indemnification obligations) shall have been
paid in full or the Defeasance thereof shall have been consummated, (ii) except
as otherwise provided in the Indenture or any other Indenture Document, to
preserve and maintain all rights in the material Intellectual Property
(including, but not limited to, with respect to Trademarks, the filing of
affidavits of use and, incontestability, where applicable, under Sections 8 and
15 of the Lanham Act (15 U.S.C. Section 1058, 1065) and renewals and, to the
extent commercially reasonable, initiating opposition or cancellation
proceedings or litigation against users of the same or confusingly similar marks
who seriously threaten the validity or rights of Grantor in its material
Trademarks), and (iii) to ensure that the Registered Intellectual Property is
and remains enforceable. The Grantee shall be reimbursed for all such costs and
expenses which constitute to the extent required under the Security Agreement or
the Indenture. Grantor shall not knowingly or unreasonably abandon any right to
file a material patent, trademark or service mark application, or abandon any
pending patent application, or any other material Intellectual Property, unless
Grantor, in the exercise of its commercially reasonable business judgment
determines that such abandonment will not materially and adverse effect its
business.

            11. Grantee's Right to Sue. Upon the occurrence and during the
continuance of an Event of Default, Grantee for the benefit of the Grantee and
the other Secured Parties shall have the right, but shall in no way be
obligated, to bring suit in its own name to enforce the Intellectual Property,
only after Grantee has tendered notice to Grantor of Grantee's desire to
initiate such suit and Grantor has declined in writing to itself pursue such
suit, and, if Grantee shall commence any such suit, Grantor shall, at the
request of Grantee, do any and all lawful acts and execute any and all proper
documents and instruments reasonably required by Grantee for the benefit of the
Grantee and the other Secured Parties in aid of such enforcement.

            12. No Waivers; Cumulative Remedies. No course of dealing between
Grantor and Grantee, nor any failure to exercise, nor any delay in exercising,
on the part of Grantee, any right, power or privilege hereunder or under the
Indenture or any other Indenture Document shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or thereunder preclude any other or further exercise thereof or the exercise of
any other right, power or privilege.

            13. Severability. The provisions of this Agreement are severable,
and if any clause or provision shall be held invalid and unenforceable in whole
or in part in any jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof,

                                     - 6 -
<PAGE>

in such jurisdiction, and shall not in any manner affect such clause or
provision in any other jurisdiction, or any other clause or provision of this
Agreement in any jurisdiction.

            14. Modification. This Agreement cannot be altered, amended or
modified in any way, except as specifically provided in Section 5 hereof or by a
writing signed by the Grantor and the Grantee.

            15. Cumulative Remedies; Power of Attorney; Effect on Indenture
Documents. All of Grantee's rights and remedies with respect to the Intellectual
Property (for the benefit of the Grantee and the other Secured Parties), whether
established hereby or by the Indenture or any other Indenture Document, or by
any other agreements or by law shall be cumulative and may be exercised
singularly or concurrently. Grantor hereby authorizes Grantee for the benefit of
the Grantee and the other Secured Parties upon the occurrence and during the
continuance of an Event of Default, to make, constitute and appoint any officer
or agent of Grantee as Grantee may select, in its sole discretion, as Grantor's
true and lawful attorney-in-fact, with power to, for the benefit of the Grantee
and the other Secured Parties, (i) endorse Grantor's name on all applications,
documents, papers and instruments necessary or desirable for Grantee in the use
of the Intellectual Property, or (ii) take any other actions with respect to the
Intellectual Property as Grantee deems in its commercially reasonable judgment
to be in the best interest of Grantee, or (iii) grant or issue any exclusive or
non-exclusive license under the Intellectual Property to any person or entity,
or (iv) assign, pledge, sell, convey or otherwise transfer title in or dispose
of any of the Intellectual Property to any person or entity. Grantor hereby
ratifies all that such attorney shall lawfully do or cause to be done by virtue
hereof. This power of attorney being coupled with an interest shall be
irrevocable until all Obligations shall have been paid in full (other than
contingent indemnification obligations) or the Defeasance thereof shall have
been consummated. Grantor acknowledges and agrees that this Agreement is not
intended to limit or restrict in any way the rights and remedies of Grantee
under the Indenture or any other Indenture Document but rather is intended to
facilitate the exercise of such rights and remedies. Grantee shall have, in
addition to all other rights and remedies given it by the terms of this
Agreement, the Indenture and the other Indenture Documents, all rights and
remedies allowed by law, in equity, and the rights and remedies of a secured
party under the Uniform Commercial Code as enacted in the State of New York.

            16. Grantor Remain Liable. Anything herein to the contrary
notwithstanding:

            (a) the Grantor will remain liable under the contracts and
      agreements included in the Intellectual Property to the extent set forth
      therein, and will perform all of its duties and obligations under such
      contracts and agreements to the same extent as if this Agreement had not
      been executed;

            (b) the exercise by the Grantee of any of its rights hereunder will
      not release the Grantor from any of its duties or obligations under any
      such contracts or agreements included in the Intellectual Property; and

            (c) no Secured Party will have any obligation or liability under any
      contracts or agreements included in the Intellectual Property by reason of
      this Agreement, nor will any such Person be obligated to perform any of
      the obligations or duties of the Grantor

                                     - 7 -
<PAGE>

      thereunder or to take any action to collect or enforce any claim for
      payment assigned hereunder.

            17. Binding Effect; Benefits. This Agreement shall be binding upon
Grantor and its respective successors and assigns, and shall inure to the
benefit of Grantee, its successors, nominees and assigns; provided, however,
that neither party may assign this Agreement or any rights or duties hereunder
other than pursuant to the terms of the Indenture.

            18. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS
MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICT OF LAWS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT.

            19. Headings; Counterparts. Paragraph headings used herein are for
convenience only and shall not modify the provisions which they precede. This
Agreement may be signed in one or more counterparts, but all of such
counterparts shall constitute and be deemed to be one and the same instrument.
Any fax signature shall be deemed to be as legally enforceable and effective as
a signed original.

            20. Further Assurances. Grantor agrees to execute and deliver such
further agreements, instruments and documents, and to perform such further acts,
as Grantee shall reasonably request from time to time in order to carry out the
purpose of this Agreement and agreements set forth herein. Grantor acknowledges
that a copy of this Agreement will be filed by the Grantee with the United
States Patent and Trademark Office and, if applicable, the United States
Copyright Office, at the sole cost and expense of Grantor.

            21. Survival of Representations. All representations and warranties
of Grantor contained in this Agreement shall survive the execution and delivery
of this Agreement.

            22. Foreign Patents, Copyrights and Trademarks. Upon the occurrence
and during the continuance of an Event of Default, at the request of Grantee and
at the sole cost and expense (including, without limitation, reasonable
attorneys' fees) of Grantor, Grantor shall take all actions and execute and
deliver any and all instruments, agreements, assignments, certificates and/or
documents, reasonably required by Grantee to collaterally assign any and all of
Grantor's foreign patent, copyright and trademark registrations and applications
now owned or hereafter acquired to and in favor of Grantee. Upon the execution
and delivery of any such collateral assignments or documents, the terms
"Patents", "Copyrights", and "Trademarks" as used herein shall automatically be
deemed amended to include such foreign patent, copyright and trademark
registrations and applications without any action required by any person or
entity.

            23. JURY TRIAL WAIVER. THE GRANTOR HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR IN

                                     - 8 -
<PAGE>

CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT.

            24. Interpretation; Government Regulation. Neither this Agreement
nor any uncertainty or ambiguity herein shall be construed against the Grantee,
any other Secured Party or the Grantor, whether under any rule of construction
or otherwise. On the contrary, this Agreement has been reviewed by all parties
and shall be construed and interpreted according to the ordinary meaning of the
words used so as to accomplish fairly the purposes and intentions of all parties
hereto.

            25. Revival and Reinstatement of Obligations. If the incurrence or
payment of the Obligations by the Grantor or the transfer by the Grantor to the
Grantee of any property of the Grantor should for any reason subsequently be
declared to be void or voidable under any state or federal law relating to
creditors' rights, including provisions of the Bankruptcy Code relating to
fraudulent conveyances, preferences, or other voidable or recoverable payments
of money or transfers of property (collectively, a "Voidable Transfer"), and if
the Grantee or any other Secured Party is required to repay or restore, in whole
or in part, any such Voidable Transfer, or elects to do so upon the reasonable
advice of its counsel, then, as to any such Voidable Transfer, or the amount
thereof that the Grantee or such other Secured Party is required or elects to
repay or restore, and as to all reasonable costs, expenses, and attorneys fees
of the Grantee or such other Secured Party related thereto, the liability of the
Grantor automatically shall be revived, reinstated, and restored and shall exist
as though such Voidable Transfer had never been made.

            26. Intercreditor Agreement.

            (a) The Liens granted hereunder in favor of Grantee for the benefit
of itself, the Trustee and the Holders in respect of the Intellectual Property
and the exercise of any right related thereto thereby shall be subject, in each
case, to the terms of the Intercreditor Agreement.

            (b) In the event of any direct conflict between the express terms
and provisions of this Agreement and of the Intercreditor Agreement, the terms
and provisions of the Intercreditor Agreement shall control.

                            [Signature Page Follows]
