Agreement shall have been terminated, Grantor shall not, without the prior
written consent of Grantee, sell, transfer, mortgage, convey, dispose, 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

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 Bank Product
Providers 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 Bank
Product Providers 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 Loan Agreement, Grantee shall have the right, from time

contingent indemnification obligations) and termination of the Loan Agreement,
to inspect Grantor's premises and to examine Grantor's books, records and
operations, including, without limitation, Grantor's quality control processes.

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 Agreement. Upon the payment and performance
in full in cash of the Obligations (other than contingent indemnification
obligations), including the cash collateralization, expiration or cancellation

final termination of any commitment to extend any financial accommodations under
the Loan Agreement, this Security 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 Bank Product Providers 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.

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

mark applications pending as of the date hereof or hereafter until all
Obligations (other than contingent indemnification obligations) shall have been
paid in full and the Loan Agreement has been terminated, (ii) except as
otherwise provided in the Loan Agreement, 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 Lender Expenses.
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 Bank Product Providers 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 Bank Product Providers in aid of such enforcement.

            12. Waivers. 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 Loan Agreement 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 Security 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, 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 Security
Agreement in any jurisdiction.

            14. Modification. This Security Agreement cannot be altered, amended
or modified in any way, except as specifically provided in Section 5 hereof or

Agreement. All of Grantee's rights and remedies with respect to the Intellectual
Property (for the benefit of the Grantee and the Bank Product Providers),
whether established hereby or by the Loan Agreement, 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 Bank
Product Providers 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 Bank
Product Providers, (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) and the Loan Agreement has been
terminated. Grantor acknowledges and agrees that this Security Agreement is not
intended to limit or restrict in any way the rights and remedies of Grantee
under the Loan Agreement but rather is intended to facilitate the exercise of
such rights and remedies. Grantee shall have, in addition to all other

                                     - 6 -

binding upon Grantor and its respective successors and assigns, and shall inure
to the benefit of Grantee, its successors, nominees and assigns; provided,
however, Grantor shall not assign this Security Agreement or any of Grantor's
obligations hereunder without the prior written consent of Grantee.

            18. Governing Law. This Security Agreement shall be governed by,
enforced and construed in accordance with the internal laws of the State of
Illinois, without regard to choice of law or conflict of law principles.

            19. Headings; Counterparts. Paragraph headings used herein are for

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

"Intercreditor Agreement") by and among the Pledgor, the Pledgee and LaSalle
Bank National Association (the "Collateral Agent"), the Pledged Collateral owned
by the Pledgor on the date hereof and the certificates representing the Pledged
Collateral accompanied by "stock powers" or an Assignment Separate From
Certificate duly executed in blank by the Pledgor. Whether or not the Pledged
Collateral is evidenced by certificates, the Pledgor hereby permits the Pledgee
to file a Code Financing Statement naming the Pledgor as debtor and the Pledgee
as secured party with respect to the Collateral with the Delaware Secretary of
State, in form and substance satisfactory to the Pledgee in its sole and
absolute determination, and without the requirement of the Pledgor's signature.
Notwithstanding anything to the contrary contained in this Agreement, the
Pledgee shall not as a result of this Agreement be responsible or liable for any
obligations or liabilities of the Pledgor in the Pledgor's capacity as a
shareholder, if any, and the Pledgee shall not be deemed to have assumed any of
such obligations or liabilities.

      3.2 Subsequently Acquired Pledged Collateral. If at any time or from time
to time after the date hereof during the term of this Agreement, the Pledgor
shall acquire any additional Pledged Interests, including any further stock or
equity in each of Viskase Films and WSC (whether by purchase, dividend, merger,
consolidation, sale of assets, split, spin-off, or any other dividend or
distribution of any kind or otherwise), if the Intercreditor Agreement is in
effect at such time, then the Pledgor will forthwith pledge and, if applicable,
deposit such additional Pledged Collateral with the Collateral Agent, for the
benefit of the Pledgee and the Collateral Agent in accordance with the terms of
the Intercreditor Agreement and deliver to the Collateral Agent, for the benefit
of the Pledgee and the Collateral Agent in accordance with the terms of the
Intercreditor Agreement, certificates or instruments therefor, endorsed in blank
by the Pledgor or accompanied by "stock powers" or an Assignment Separate From
Certificate duly executed in blank by the Pledgor, and will promptly thereafter
deliver to the Collateral Agent, for the benefit of the Pledgee and the
Collateral Agent in accordance with the terms of the Intercreditor Agreement, a
certificate (which shall be deemed to supplement Annex A attached hereto)
executed by the Pledgor describing such Pledged Collateral and the other Pledged
Collateral pledged to the Pledgee, and certifying that the same have been duly
pledged with the Pledgee hereunder. If the Intercreditor Agreement is not in
effect at such time, then the Pledgor will

                                     - 2 -
<PAGE>

make such deposits directly to the Pledgee. Whether or not such additional
Pledged Collateral is evidenced by certificates, the Pledgor shall permit the
Pledgee to file a Code Financing Statement naming the Pledgor as debtor and the
Pledgee as secured party with respect to the additional Collateral with the
Delaware Secretary of State, in form and substance satisfactory to the Pledgee
in its sole and absolute determination, and without the requirement of the
Pledgor's signature.

      3.3 Uncertificated Pledged Collateral. In addition to anything contained
in Sections 3.1 and 3.2 hereof, if any Pledged Collateral (whether now owned or
hereafter acquired) is not certificated or becomes an uncertificated security,
the Pledgor shall promptly notify the Pledgee thereof and shall promptly take
all actions required to perfect the security interest and pledge in favor of the
Pledgee under applicable law (including, in any event, any action required or
appropriate under this Agreement or the Code). The Pledgor further agrees to
take such actions as the Pledgee deems necessary or desirable to effectuate the
foregoing and to permit the Pledgee to exercise any of its rights and remedies
hereunder.

      4. VOTING, ETC. Until the occurrence and continuance of an Event of
Default (as defined in the Loan Agreement), the Pledgor shall be entitled to
vote any and all of the Pledged Collateral; provided; however, that no vote
shall be cast or any action taken by Pledgor which would violate or be
materially inconsistent with any of the terms of this Agreement, the Loan
Agreement, any other Loan Document, or which would have the effect of materially
impairing the position or interests of the Pledgee or which would authorize or
effect actions prohibited under the terms of the Loan Agreement or any Loan
Document. All such rights of the Pledgor to vote shall cease upon the occurrence
and during the continuance of an Event of Default, if the Pledgee so directs and
provides notice to the Pledgor to do so; provided, however, that upon the cure
or waiver of such Event of Default, all rights of the Pledgee to vote any and
all of the Pledged Collateral shall cease.

      5. PAYMENTS AND OTHER DISTRIBUTIONS. Until the occurrence and continuance
of an Event of Default and subject in all cases to the Intercreditor Agreement,
all cash, dividends or distributions payable in respect of the Pledged
Collateral (to the extent such payments shall be permitted pursuant to the terms
and provisions of the Loan Agreement) shall be paid to the Pledgor; provided,
however, upon the occurrence and during the continuance of an Event of Default,
all cash dividends or distributions payable in respect of the Pledged Collateral
shall be paid to the Pledgee as security for the Obligations if the Pledgee so
directs and provides notice to the Pledgor to that effect; provided, further
that upon the cure or waiver of such Event of Default, all cash dividends or
distributions payable in respect of the Pledged Collateral shall be paid to the
Pledgor. The Pledgee shall be entitled to receive directly, and to retain as
part of the Collateral:

      (a) all other or additional securities or investment property, or rights
to subscribe for or purchase any of the foregoing, or property (other than cash)
paid or distributed by way of dividend in respect of the Pledged Collateral; and

      (b) all other or additional securities, investment property or property
(including cash) paid or distributed in respect of the Pledged Collateral by way
of split, spin-off, split-up, reclassification, combination of shares or similar
rearrangement.

                                     - 3 -
<PAGE>

      Subject to the Intercreditor Agreement, if at any time the Pledgor shall
obtain or possess any of the foregoing Collateral described in this Section, the
Pledgor shall be deemed to hold such Collateral in trust for the Pledgee for the
benefit of the Pledgee and the Bank Product Providers, and the Pledgor shall
promptly surrender and deliver such Collateral to the Pledgee.

      6. REMEDIES IN CASE OF AN EVENT OF DEFAULT. Subject to the Intercreditor
Agreement, upon the occurrence and during the continuance of an Event of
Default, the Pledgee shall be entitled to exercise all of the rights, powers and
remedies (whether vested in it by this Agreement, the Loan Agreement, any other
Loan Documents, and/or in equity or by law, and including, without limitation,
all rights and remedies of a secured party of a debtor in default under the
Code) for the protection and enforcement of its rights in respect of the Pledged
Collateral, and to the fullest extent permitted by applicable law, the Pledgee
shall be entitled, without limitation, to exercise the following rights, which
the Pledgor hereby agrees to be commercially reasonable:

      (a) to receive all amounts payable to the Pledgor in respect of the
Pledged Collateral in accordance with Section 5 hereof;

      (b) to transfer all or any part of the Pledged Collateral into the
Pledgee's name or the name of its nominee or nominees for the benefit of the
Pledgee and the Bank Product Providers;

      (c) to vote all or any part of the Pledged Collateral and otherwise act
with respect thereto as though it were the outright owner thereof in accordance
with Section 4 hereof;

      (d) at any time or from time to time to sell, assign and deliver, or grant
options to purchase, all or any part of the Pledged Collateral in one or more
parcels, or any interest therein, at any public or private sale at any exchange,
broker's board or at any of the Pledgee's offices or elsewhere, without demand
of performance, advertisement or notice of intention to sell or of time or place
of sale or adjournment thereof or to redeem (all of which, except as may be
required by mandatory provisions of applicable law, are hereby expressly and
irrevocably waived by the Pledgor) for cash, on credit or for other property,
for immediate or future delivery without any assumption of credit risk, and for
such price or prices and on such terms as the Pledgee in its commercially
reasonable judgment may determine. The Pledgor agrees that to the extent that
notice of sale shall be required by law that at least ten (10) calendar days'
notice to the Pledgor of the time (which shall be during normal business hours)
and place of any public sale or the time after which any private sale is to be
made shall constitute reasonable notification. The Pledgee shall not be
obligated to make any sale of Pledged Collateral regardless of notice of sale
having been given. The Pledgee may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and any such sale
may, without further notice, be made at the time and place to which it was so
adjourned. The Pledgor hereby waives and releases to the fullest extent
permitted by law any right or equity of redemption with respect to the Pledged
Collateral, whether before or after sale hereunder, and all rights, if any of
marshalling the Pledged Collateral and any other security for the Obligations or
otherwise. At any such sale, unless prohibited by applicable law, the Pledgee
may bid for and purchase all or any part of the Pledged Collateral so sold free
from any such right or equity of redemption. Neither the Pledgee nor any of the
Bank Product Providers shall be liable for failure to collect or realize upon
any or all of the Pledged Collateral or for any delay in so doing nor shall the

                                     - 4 -
<PAGE>

Pledgee nor any of the Bank Product Providers be under any obligation to take
any action whatsoever with regard thereto;

      (e) to settle, adjust, compromise and arrange all accounts, controversies,
questions, claims and demands whatsoever in relation to all or any part of the
Pledged Collateral;

      (f) in respect of the Pledged Collateral, to execute all such contracts,
agreements, deeds, documents and instruments, to bring, defend and abandon all
such actions, suits and proceedings, and to take all actions in relation to all
or any part of the Pledged Collateral as the Pledgee in its reasonable
discretion may determine;

      (g) to appoint managers, sub-agents, officers and servants for any of the
purposes mentioned in the foregoing provisions of this Section and to dismiss
the same, all as the Pledgee in its reasonable discretion may determine; and

      (h) generally, to take all such other action as the Pledgee in its
reasonable discretion may determine as incidental or conducive to any of the
matters or powers mentioned in the foregoing provisions of this Section and
which the Pledgee may or can do lawfully and to use the name of the Pledgor for
the purposes aforesaid and in any proceedings arising therefrom.

      7. REMEDIES, ETC., CUMULATIVE. Each right, power and remedy of the Pledgee
(for the benefit of the Pledgee and the Bank Product Providers) provided for in
this Agreement, the Loan Agreement, any Loan Document (as defined in the Loan
Agreement) or any other security agreement, mortgage, guaranty or now or
hereafter existing at law or in equity or by statute shall be cumulative and
concurrent and shall be in addition to every other such right, power or remedy.
The exercise or beginning of the exercise by the Pledgee (for the benefit of the
Pledgee and the Bank Product Providers) of any one or more of the rights, powers
or remedies provided for in this Agreement, the Loan Agreement, or any other
Loan Document or now or hereafter existing at law or in equity or by statute or
otherwise shall not preclude the simultaneous or later exercise by the Pledgee
of all such other rights, powers or remedies, and no failure or delay on the
part of the Pledgee to exercise any such right, power or remedy shall operate as
a waiver thereof.

      8. APPLICATION OF PROCEEDS. Subject to any mandatory requirements of
applicable law and the terms of the Loan Agreement and the Intercreditor
Agreement, all moneys collected by the Pledgee (for the benefit of the Pledgee
and the Bank Product Providers) upon sale or other disposition of the
Collateral, together with all other moneys received by the Pledgee hereunder,
shall be applied as follows:

      (a) To the payment of any and all Lender Expenses;

      (b) Next, to the payment of the Obligations in accordance with the Loan
Agreement; and

      (c) Any surplus then remaining shall be paid to the Pledgor.

      9. INDEMNITY. Without duplication of any amounts payable under any other
similar indemnity provision set forth in the Loan Agreement or any other Loan
Documents, the

                                     - 5 -

counsel for the Pledgee); (ii) pay and hold the Pledgee and the Bank Product

pay any such taxes, charges or levies; and (iii) indemnify the Pledgee and each

any of them (whether or not any of them is designated a party thereto) arising
out of or by reason of this Agreement or any transaction contemplated hereby
(including, without limitation, any investigation, litigation or other
proceeding related to this Agreement), including, without limitation, the
reasonable fees and disbursements of counsel incurred in connection with any
such investigation, litigation or other proceeding. Notwithstanding anything in
this Agreement to the contrary, the Pledgor shall not be responsible to the
Pledgee or any Bank Product Provider for any costs, losses, damages, liabilities
or expenses which result from the gross negligence or willful misconduct on the
part of such Pledgee or any Bank Product Provider. The Pledgor's obligations
under this Section shall survive any termination of this Agreement.

      10. FURTHER ASSURANCES. Pledgor agrees that, at any time and from time to
time, the Pledgor will join with the Pledgee in executing and, at the Pledgor's
own expense, will file and refile under the Code such financing statements,
continuation statements and other documents in such offices as the Pledgee may
deem necessary or appropriate and wherever required or permitted by law in order
to perfect and preserve the Pledgee's security interest in the Collateral, and
hereby authorizes the Pledgee to file financing statements and amendments
thereto relative to all or any part of the Collateral without the signature of
the Pledgor, and agrees to do such further acts and things and to promptly
execute and deliver to the Pledgee such additional conveyances, assignments,
agreements and instruments as the Pledgee may require or deem advisable to carry
into effect the purpose of this Agreement or to further assure and confirm unto
the Pledgee its rights, powers and remedies hereunder.

      11. REASONABLE CARE BY PLEDGEE. The Pledgee shall be deemed by the Pledgor
to have exercised reasonable care in the custody and preservation of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which the Pledgee accords its own similar property.

      12. TRANSFER BY THE PLEDGOR. Except as otherwise permitted under the Loan
Agreement, if at all, the Pledgor shall not sell, transfer or otherwise dispose
of, grant any option with respect to, or pledge or otherwise encumber any of the
Collateral or any interest therein.

represents and warrants to the Pledgee for the benefit of the Pledgee and the

Pledgor and each and every person or entity claiming by, through and under the

      17. POWER OF ATTORNEY. Pledgor hereby absolutely and irrevocably
constitutes and appoints the Pledgee for the benefit of the Pledgee and the Bank
Product Providers as Pledgor's true and lawful agent and attorney-in-fact with
full power of substitution, in the name of Pledgor upon the occurrence and
during the continuance of an Event of Default: (a) to execute and do all such
assurances, acts and things which the Pledgor ought to do but has failed to do
under the covenants and provisions contained in this Agreement; (b) to take any
and all such action as the Pledgee or any of its sub-agents, nominees or
attorneys may, in its or their commercially reasonable discretion, reasonably
determine as necessary or advisable for the purpose of maintaining preserving or
protecting the security constituted by this Agreement or any of the rights,
remedies, powers or privileges of the Pledgee under this Agreement; and (c)
generally, in the name of the Pledgor, exercise all or any of the powers,
authorities, and discretions conferred on or reserved to the Pledgee by or
pursuant to this Agreement, and (without prejudice to the generality of any of
the foregoing) to deliver or otherwise perfect any deed, assurance, agreement,
instrument or act as the Pledgee may deem proper in or for the purpose of
exercising any of such powers, authorities or discretions. The Pledgor hereby
ratifies and confirms, and hereby agrees to ratify and confirm, whatever lawful
acts the Pledgee or any of the Pledgee's sub-agents or attorneys shall do or
purport to do in the exercise of the power of attorney granted to the Pledgee
pursuant to this Section, which power of attorney, being coupled with an
interest and given for security, is irrevocable; provided, however, that the
Pledgor neither ratifies nor confirms any acts of the Pledgee or any of the
Pledgee's sub-agents or attorneys do in the exercise of this power of attorney
if such acts constitute the gross negligence or willful misconduct of such
Person.

      18. MISCELLANEOUS. The Pledgor agrees with the Pledgee that each of the
obligations and liabilities of the Pledgor to the Pledgee under this Agreement
may be enforced against the Pledgor without the necessity of joining any other
Person (as defined in the Loan Agreement) as a party. This Agreement shall
create a continuing security interest in the Pledged Collateral and shall be
binding upon the heirs and legal beneficiaries, and permitted successors and
assigns, of the Pledgor, as applicable, and shall inure to the benefit of and be
enforceable by

                                     - 10 -
<PAGE>

the Pledgee and its successors and assigns. Unless otherwise defined herein,
terms defined in the Code are used herein as therein defined. The headings and
titles in this Agreement are for convenience of reference only and shall not
limit or define the meaning hereof. This Agreement may be executed in any number
of counterparts, each of which shall be an original, but all of which shall
constitute one instrument. If any provision of this Agreement shall prove to be
invalid or unenforceable, such provision shall be deemed to be severable from
the other provisions of this Agreement which shall remain binding on all parties
hereto. The Pledgor shall have no rights of subrogation as to any of the Pledged
Collateral until full and complete performance and payment of the Obligations
(other than contingent indemnification obligations). A signature hereto
distributed by facsimile or electronic mail shall be deemed to be as legally
binding as a signed original.

      19. TERMINATION; RECOVERY CLAIM. This Agreement shall terminate after the
Obligations are paid in full (other than contingent indemnification obligations)

the same (without recourse and without any representation or warranty of any
kind) such of the Pledged Collateral as may be in the possession of the Pledgee
and has not theretofore been sold or otherwise applied or released pursuant to
this Agreement. Should a claim ("Recovery Claim") be made upon the Pledgee or
any or all of the Bank Product Providers at any time for recovery of any amount
received by the Pledgee or any or all of the Bank Product Providers in payment
of the Obligations (whether received from Pledgor or otherwise) and should the
Pledgee or any or all of the Bank Product Providers repay all or part of said
amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Pledgee or any or all of the
Bank Product Providers or any of their respective property; or (b) any
settlement or compromise of any such Recovery Claim effected by the Pledgee or
any or all of the Bank Product Providers with the claimant (including, without
limitation, Pledgor), this Agreement and the security interests granted to the
Pledgee for the benefit of the Pledgee and the Bank Product Providers hereunder
shall continue in effect with respect to the amount so repaid to the same extent
as if such amount had never originally been received by the Pledgee or any or
all of the Bank Product Providers, notwithstanding any prior termination of this
Agreement, the return of this Agreement to the Pledgor, or the cancellation of
any note or other instrument evidencing the Obligations.

      20. AMENDMENTS; MARSHALLING, ETC. None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by the Pledgor and the Pledgee. The Pledgee shall be
under no obligation to marshal any assets or collateral in favor of the Pledgor
or any other person or entity or against or in payment of any or all of the
Obligations. All indemnities set forth herein shall survive the execution and
delivery of this Agreement and the making and repayment of the Obligations. The
Bank Product Providers are the intended third party beneficiaries of this
Agreement.
