and valuable consideration, receipt and sufficiency of which are hereby

            1. Incorporation of Financing Agreements. The Financing Agreements
and the terms and provisions thereof are hereby incorporated herein in their
entirety by this reference thereto. All terms capitalized but not otherwise
defined herein shall have the same meanings herein as in the Loan Agreement.

            2. Grant and Reaffirmation of Grant of Security Interests. To secure
the complete and timely payment and satisfaction of the Liabilities, Company
hereby grants to Agent, for the benefit of Agent and Lenders, and hereby
reaffirms its prior grant pursuant to the Financing Agreements of, a continuing

its now owned or existing and hereafter acquired or arising patents and patent
applications, including, without limitation, the inventions and improvements
described and claimed therein, all patentable inventions and those patents and
patent applications listed on Schedule A attached hereto and made a part hereof

and future infringements of any of the foregoing and the right to sue for past,
present and future infringements of any of the foregoing (all of the foregoing
are sometimes hereinafter individually and/or collectively referred to as the
"Patents").

            3. Warranties and Representations. Company warrants and represents
to Agent and Lenders that:

            (i) no Patent has been adjudged invalid or unenforceable by a court
      of competent jurisdiction nor has any such Patent been cancelled, in whole
      or in part and each such Patent is presently subsisting;

            (ii) Except as provided in the Loan Agreement, Company is the sole
      and exclusive owner of the entire and unencumbered right, title and
      interest in and to each Patent, free and clear of any liens, charges and
      encumbrances, including without limitation, shop rights and covenants by
      Company not to sue third persons;

            (iii) Company has no notice of any suits or actions commenced or
      threatened with reference to any Patent; and

            (iv) Company has the unqualified right to execute and deliver this
      Security Agreement and perform its terms.

            4. Restrictions on Future Agreements. Company agrees that until
Company's Liabilities shall have been satisfied in full and the Financing
Agreements shall have been terminated, Company shall not, without the prior
written consent of Agent, sell or assign its interest in any Patent or enter
into any other agreement with respect to any Patent which would affect the
validity or enforcement of the rights transferred to Agent under this Security
Agreement.

            5. New Patents. Company represents and warrants that, based on a
diligent investigation by Company, the Patents listed on Schedule A constitute
all of the federally registered Patents and Patent applications now owned by
Company. If, before Company's Liabilities shall have been satisfied in full or
before the Financing Agreements have been terminated, Company shall (i) become
aware of any existing Patents of which Company has not previously informed
Agent, (ii) obtain rights to any new patentable inventions or Patents, or (iii)
become entitled to the benefit of any Patents, which benefit is not in existence
on the date hereof, the provisions of this Security Agreement above shall
automatically apply thereto and Company shall give to Agent prompt written
notice thereof. Company hereby authorizes Agent to modify this Security
Agreement by amending Schedule A to include any such Patents.

            6. Royalties; Terms. The term of this Security Agreement shall
extend until the earlier of (i) the expiration of each of the Patents, and (ii)
the payment in full of Company's Liabilities and the termination of the
Financing Agreements. Company agrees


                                      -2-
<PAGE>

that upon the occurrence of an Event of Default, the use by Agent of all Patents
shall be without any liability for royalties or other related charges from Agent
to Company.

            7. Release of Security Interest. This Security Agreement is made for
collateral purposes only. Upon payment in full of Company's Liabilities and
termination of the Financing Agreements, Agent shall take such actions as may be
necessary or proper to terminate the security interests created hereby and
pursuant to the Financing Agreements

            8. Expenses. All expenses incurred in connection with the
performance of any of the agreements set forth herein shall be borne by Company.
All fees, costs and expenses, of whatever kind or nature, including reasonable
attorneys' fees and legal expenses, incurred by Agent 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, reasonable
counsel fees, maintenance fees, encumbrances or otherwise in protecting,
maintaining or preserving the Patents or in defending or prosecuting any actions
or proceedings arising out of or related to the Patents shall be borne by and
paid by Company and until paid shall constitute Liabilities.

            9. Duties of Company. Company shall have the duty (i) to file and
prosecute diligently any patent applications pending as of the date hereof or
hereafter until Company's Liabilities shall have been paid in full and the
Financing Agreements have been terminated, (ii) to make application on
unpatented but patentable inventions, as commercially reasonable, (iii) to
preserve and maintain all rights in the Patents, as commercially reasonable and
(iv) to ensure that the Patents are and remain enforceable, as commercially
reasonable. Any expenses incurred in connection with Company's obligations under
this Section 9 shall be borne by Company.

            10. Agent's Right to Sue. After an Event of Default, Agent shall
have the right, but shall in no way be obligated, to bring suit in its own name
to enforce the Patents and, if Agent shall commence any such suit, Company
shall, at the request of Agent, do any and all lawful acts and execute any and
all proper documents required by Agent in aid of such enforcement and Company
shall promptly, upon demand, reimburse and indemnify Agent for all costs and
expenses incurred by Agent in the exercise of its rights under this Section 10.

            11. Waivers. No course of dealing between Company, Agent and
Lenders, nor any failure to exercise, nor any delay in exercising, on the part
of Agent, any right, power or privilege hereunder or under the Financing
Agreements 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.

            12. 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


                                      -3-
<PAGE>

or provision in any other jurisdiction, or any other clause or provision of this
Security Agreement in any jurisdiction.

            13. Modification. This Security 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 parties hereto.

            14. Cumulative Remedies; Power of Attorney; Effect on Financing
Agreements. All of Agent's rights and remedies with respect to the Patents,
whether established hereby or by the Financing Agreements, or by any other
agreements or by law shall be cumulative and may be exercised singularly or
concurrently. Company hereby authorizes Agent upon the occurrence of an Event of
Default, to make, constitute and appoint any officer or agent of Agent as Agent
may select, in its sole discretion, as Company's true and lawful
attorney-in-fact, with power to (i) endorse Company's name on all applications,
documents, papers and instruments necessary or desirable for Agent in the use of
the Patents or (ii) take any other actions with respect to the Patents as Agent
deems to be in the best interest of Agent, or (iii) grant or issue any exclusive
or non-exclusive license under the Patents to anyone, or (iv) assign, pledge,
convey or otherwise transfer title in or dispose of the Patents to anyone.
Company 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 Company's Liabilities shall have been paid in full
and the Financing Agreements have been terminated. Company acknowledges and
agrees that this Security Agreement is not intended to limit or restrict in any
way the rights and remedies of Agent under the Financing Agreements but rather
is intended to facilitate the exercise of such rights and remedies. Agent shall
have, in addition to all other rights and remedies given it by the terms of this
Security Agreement and the Financing Agreements, all rights and remedies allowed
by law and the rights and remedies of a secured party under the Uniform
Commercial Code as enacted in Illinois.

            15. Binding Effect; Benefits. This Security Agreement shall be
binding upon Company and its respective successors and assigns, and shall inure
to the benefit of Agent, its successors, nominees and assigns.

            16. Governing Law. This Security Agreement shall be governed by and
construed in accordance with the laws of the State of Illinois and applicable
federal law.

            17. Headings. Paragraph headings used herein are for convenience
only and shall not modify the provisions which they precede.

            18. Further Assurances. Company agrees to execute and deliver such
further agreements, instruments and documents, and to perform such further acts,
as Agent shall reasonably request from time to time in order to carry out the
purpose of this Security Agreement and agreements set forth herein.

            19. Survival of Representations. All representations and warranties
of Company contained in this Security Agreement shall survive the execution and
delivery of


                                      -4-

this Security Agreement and shall be remade on the date of each borrowing under
the Financing Agreements.
