been taken to perfect the Security Interest to create in favor of the Secured
Party valid, perfected and continuing first priority liens in the Intellectual
Property to the extent they can be perfected through such filings.

                  (e) This Agreement creates in favor of the Secured Party a
valid security interest in the Intellectual Property securing the payment and

interest in the Intellectual Property and the goodwill and general intangibles
of the Company relating thereto or represented thereby, and the Company hereby
appoints the Secured Party its attorney-in-fact to execute and file all such
writings for the foregoing purposes, all acts of such attorney being hereby
ratified and confirmed; such power being coupled with an interest is irrevocable
until the Obligations have been fully satisfied and are paid in full.

                  (g) The execution, delivery and performance of this Agreement

without the passage of time or notice, shall constitute a breach or default,
under any agreement to which the Company is a party or by which the Company is
bound. No consent (including, without limitation, from stock holders or
creditors of the Company) is required for the Company to enter into and perform
its obligations hereunder.

                  (h) The Company shall at all times maintain the liens and
Security Interest provided for hereunder as valid and perfected first priority

the Security Interest hereunder shall terminate pursuant to Section 11. The
Company hereby agrees to defend the same against any and all persons. The
Company shall safeguard and protect all Intellectual Property for the account of
the Secured Party. Without limiting the generality of the foregoing, the Company
shall pay all fees, taxes and other amounts necessary to maintain the
Intellectual Property and the Security Interest hereunder, and the Company shall
obtain and furnish to the Secured Party from time to time, upon demand, such
releases and/or subordinations of claims and liens which may be required to
maintain the priority of the Security Interest hereunder.

                  (i) The Company will not transfer, pledge, hypothecate,
encumber, license (except for non-exclusive licenses granted by the Company in
the ordinary course of business), sell or otherwise dispose of any of the

                  (j) The Company shall, within ten (10) days of obtaining
knowledge thereof, advise the Secured Party promptly, in sufficient detail, of
any substantial change in the Intellectual Property, and of the occurrence of
any event which would have a material adverse effect on the value of the
Intellectual Property or on the Secured Party's security interest therein.

                  (k) The Company shall permit the Secured Party and its
representatives and agents to inspect the Intellectual Property at any time, and
to make copies of records pertaining to the Intellectual Property as may be
requested by the Secured Party from time to time.

                  (m) The Company shall promptly notify the Secured Party in
sufficient detail upon becoming aware of any attachment, garnishment, execution
or other legal process levied against any Intellectual Property and of any other
information received by the Company that may materially affect the value of the
Intellectual Property, the Security Interest or the rights and remedies of the
Secured Party hereunder.

                  (n) All information heretofore, herein or hereafter supplied

of such Licenses, Patents, Trademarks, Copyrights and Trade Secrets is the
subject of any licensing or franchise agreement. To the best of the Company's
knowledge, no holding, decision or judgment has been rendered by any

is pending (i) seeking to limit, cancel or question the validity of any License,
Patent, Trademark, Copyright or Trade Secret, or (ii) which, if adversely

Patent, Trademark, Copyright or Trade Secret. The Company has used and will
continue to use for the duration of this Agreement, proper statutory notice in
connection with its use of the Patents, Trademarks and Copyrights and consistent
standards of quality in products leased or sold under the Patents, Trademarks

      Copyright Licenses in the United States Copyright Office;

                        (iv) other than as set forth in Schedule B, the Company
      is the exclusive owner of the entire and unencumbered right, title and

Company shall reasonably determine is of negligible economic value to the
Company, the Company shall:

                        (i) maintain each Trademark and Copyright in full force
      free from any claim of abandonment for non-use, maintain as in the past

      Copyright; employ such Trademark or Copyright with the appropriate notice
      of registration; not adopt or use any mark which is confusingly similar or
      a colorable imitation of such Trademark or Copyright unless the Secured
      Party shall obtain a perfected security interest in such mark pursuant to
      this Agreement; and not (and not permit any licensee or sublicensee
      thereof to) do any act or knowingly omit to do any act whereby any
      Trademark or Copyright may become invalidated;

                        (ii) not, except with respect to any Patent that it
      shall reasonably determine is of negligible economic value to it, do any
      act, or omit to do any act, whereby any Patent may become abandoned or
      dedicated; and

                        (iii) notify the Secured Party immediately if it knows,
      or has reason to know, that any application or registration relating to
      any Patent, Trademark or Copyright may become abandoned or dedicated, or
      of any adverse determination or development (including, without
      limitation, the institution of, or any such determination or development

the fiscal quarter in which such filing occurs.

                  (t) The Company shall take all reasonable and necessary steps,
including, without limitation, in any proceeding before the United States Patent
and Trademark Office or the United States Copyright Office, to maintain and
pursue each application (and to obtain the relevant registration) and to
maintain each registration of the Patents, Trademarks and Copyrights, including,
without limitation, filing of applications for renewal, affidavits of use and
affidavits of incontestability.

                  (u) In the event that any Patent, Trademark or Copyright
included in the Intellectual Property is infringed, misappropriated or diluted
by a third party, the Company shall promptly notify the Secured Party after it
learns thereof and shall, unless it shall reasonably determine that such Patent,
Trademark or Copyright is of negligible economic value to it, which
determination it shall promptly report to the Secured Party, promptly sue for
infringement, misappropriation or dilution, to seek injunctive relief where

misappropriation or dilution, or take such other actions as it shall reasonably
deem appropriate under the circumstances to protect such Patent, Trademark or

fully with any enforcement action undertaken by the Secured Party on behalf of

Debentures) under the Debentures;

                  (b) Any representation or warranty of the Company in this
Agreement or in the Security Agreement shall prove to have been incorrect in any

            5. DUTY TO HOLD IN TRUST. Upon the occurrence of any Event of
Default and at any time thereafter, the Company shall, upon receipt by it of any
revenue, income or other sums subject to the Security Interest, whether payable
pursuant to the Debentures or otherwise, or of any check, draft, note, trade
acceptance or other instrument evidencing an obligation to pay any such sum,
hold the same in trust for the Secured Party and shall forthwith endorse and
transfer any such sums or instruments, or both, to the Secured Party for
application to the satisfaction of the Obligations.

            6. RIGHTS AND REMEDIES UPON DEFAULT. Upon occurrence of any Event of
Default and at any time thereafter, the Secured Party shall have the right to
exercise all of the remedies conferred hereunder and under the Debentures, and
the Secured Party shall have all the rights and remedies of a secured party
under the UCC and/or any other applicable law (including the Uniform Commercial
Code of any jurisdiction in which any Intellectual Property is then located).
Without limitation, the Secured Party shall have the following rights and
powers:

                  (a) to take possession of the Intellectual Property and, for
that purpose, enter, with the aid and assistance of any person, any premises
where the Intellectual Property, or any part thereof, is or may be placed and
remove the same, and the Company shall assemble the Intellectual Property and
make it available to the Secured Party at places which the Secured Party shall
reasonably select, whether at the Company's premises or elsewhere, and make
available to the Secured Party, without rent, all of the Company's respective
premises and facilities for the purpose of the Secured Party taking possession
of, removing or putting the Intellectual Property in saleable or disposable
form; and

                  (b) to operate the business of the Company using the
Intellectual Property and shall have the right to assign, sell, lease or
otherwise dispose of and deliver all or any part of the Intellectual Property,
at public or private sale or otherwise, either with or without special
conditions or stipulations, for cash or on credit or for future delivery, in
such parcel or parcels and at such time or times and at such place or places,
and upon such terms and conditions as the Secured Party may deem commercially
reasonable, all without (except as shall be required by applicable statute and
cannot be waived) advertisement or demand upon or notice to the Company or right
of redemption of the Company, which are hereby expressly waived. Upon each such
sale, lease, assignment or other transfer of Intellectual Property, the Secured
Party may, unless prohibited by applicable law which cannot be waived, purchase
all or any part of the Intellectual Property being sold, free from and
discharged of all trusts, claims, right of redemption and equities of the
Company, which are hereby waived and released.

            7. APPLICATIONS OF PROCEEDS. The proceeds of any such sale, lease or
other disposition of the Intellectual Property hereunder shall be applied first,
to the expenses of retaking, holding, storing, processing and preparing for
sale, selling, and the like (including, without limitation, any

                                       7
<PAGE>

taxes, fees and other costs incurred in connection therewith) of the
Intellectual Property, to the reasonable attorneys' fees and expenses incurred
by the Secured Party in enforcing its rights hereunder and in connection with
collecting, storing and disposing of the Intellectual Property, and then to
satisfaction of the Obligations, and to the payment of any other amounts
required by applicable law, after which the Secured Party shall pay to the
Company any surplus proceeds. If, upon the sale, license or other disposition of
the Intellectual Property, the proceeds thereof are insufficient to pay all
amounts to which the Secured Party is legally entitled, (i) then the proceeds
shall be allocated among the Secured Party in proportion to the amount
outstanding under each Debenture, and (ii) the Company will be liable for the
deficiency, together with interest thereon, at the rate of fifteen (15%) percent
per annum (the "DEFAULT RATE"), and the reasonable fees of any attorneys
employed by the Secured Party to collect such deficiency. To the extent
permitted by applicable law, the Company waives all claims, damages and demands
against the Secured Party arising out of the repossession, removal, retention or
sale of the Intellectual Property, unless due to the gross negligence or willful
misconduct of the Secured Party.

            8. COSTS AND EXPENSES. The Company agrees to pay all out-of-pocket
fees, costs and expenses incurred in connection with any filing required
hereunder, including without limitation, any financing statements, continuation
statements, partial releases and/or termination statements related thereto or
any expenses of any searches reasonably required by the Secured Party. The
Company shall also pay all other claims and charges which in the reasonable
opinion of the Secured Party might prejudice, imperil or otherwise affect the
Intellectual Property or the Security Interest therein. The Company will also,
upon demand, pay to the Secured Party the amount of any and all reasonable
expenses, including the reasonable fees and expenses of its counsel and of any
experts and agents, which the Secured Party may incur in connection with (i) the
enforcement of this Agreement, (ii) the custody or preservation of, or the sale
of, collection from, or other realization upon, any of the Intellectual
Property, or (iii) the exercise or enforcement of any of the rights of the
Secured Party under the Debentures. Until so paid, any fees payable hereunder
shall be added to the principal amount of the Debentures and shall bear interest
at the Default Rate.

            9. RESPONSIBILITY FOR INTELLECTUAL PROPERTY. The Company assumes all
liabilities and responsibility in connection with all Intellectual Property, and
the obligations of the Company hereunder or under the Debentures and the
Warrants shall in no way be affected or diminished by reason of the loss,
destruction, damage or theft of any of the Intellectual Property or its
unavailability for any reason.

            10. SECURITY INTEREST ABSOLUTE. All rights of the Secured Party and
all Obligations of the Company hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Debentures, the Warrants or any agreement entered into in connection with
the foregoing, or any portion hereof or thereof; (b) any change in the time,
manner or place of payment or performance 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 the Debentures, the Warrants or any other agreement entered
into in connection with the foregoing; (c) any exchange, release or
nonperfection of any of the Intellectual Property, or any release or amendment
or waiver of or consent to departure from any other Intellectual Property for,
or any guaranty, or any other security, for all or any of the Obligations; (d)
any action by the Secured Party to obtain, adjust, settle and cancel in its sole
discretion any insurance claims or matters made or arising in connection with
the Intellectual Property; or (e) any other circumstance which might otherwise
constitute any legal or equitable defense available to the Company, or a
discharge of all or any part of the Security Interest granted hereby. Until the
Obligations shall have been paid and performed in full, the rights of the
Secured Party shall continue even if the Obligations are barred for any reason,
including, without limitation, the running of the statute of limitations or
bankruptcy. The Company expressly waives presentment, protest and notice of
protest. In the event that at any time any transfer of any Intellectual Property
or any payment received by the

                                       8
<PAGE>

Secured Party hereunder shall be deemed by final order of a court of competent
jurisdiction to have been a voidable preference or fraudulent conveyance under
the bankruptcy or insolvency laws of the United States, or shall be deemed to be
otherwise due to any party other than the Secured Party, then, in any such
event, the Company's obligations hereunder shall survive cancellation of this
Agreement, and shall not be discharged or satisfied by any prior payment thereof
and/or cancellation of this Agreement, but shall remain a valid and binding
obligation enforceable in accordance with the terms and provisions hereof. The
Company waives all right to require the Secured Party to proceed against any
other person or to apply any Intellectual Property which the Secured Party may
hold at any time, or to marshal assets, or to pursue any other remedy. The
Company waives any defense arising by reason of the application of the statute
of limitations to any obligation secured hereby.

            11. TERM OF AGREEMENT. This Agreement and the Security Interest
shall terminate on the date on which all payments under the Debentures have been
made in full and all other Obligations have been paid or discharged. Upon such
termination, the Secured Party, at the request and at the expense of the
Company, will join in executing any termination statement with respect to any
financing statement executed and filed pursuant to this Agreement.

            12. POWER OF ATTORNEY; FURTHER ASSURANCES.

                  (a) The Company authorizes the Agent, as the agent for the
Secured Party, and does hereby make, constitute and appoint it, and its
respective officers, agents, successors or assigns with full power of
substitution, as the Company's true and lawful attorney-in-fact, with power, in
its own name or in the name of the Company, to, after the occurrence and during
the continuance of an Event of Default, (i) endorse any notes, checks, drafts,
money orders, or other instruments of payment (including payments payable under
or in respect of any policy of insurance) in respect of the Intellectual
Property that may come into possession of the Agent or any Secured Party; (ii)
to sign and endorse any UCC financing statement or any invoice, freight or
express bill, bill of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications and notices in connection with accounts, and
other documents relating to the Intellectual Property; (iii) to pay or discharge
taxes, liens, security interests or other encumbrances at any time levied or
placed on or threatened against the Intellectual Property; (iv) to demand,
collect, receipt for, compromise, settle and sue for monies due in respect of
the Intellectual Property; and (v) generally, to do, at the option of the Agent,
and at the Company's expense, at any time, or from time to time, all acts and
things which the Agent deems necessary to protect, preserve and realize upon the
Intellectual Property and the Security Interest granted therein in order to
effect the intent of this Agreement, the Debentures and the Warrants, all as
fully and effectually as the Company might or could do; and the Company hereby
ratifies all that said attorney shall lawfully do or cause to be done by virtue
hereof. This power of attorney is coupled with an interest and shall be
irrevocable for the term of this Agreement and thereafter as long as any of the
Obligations shall be outstanding.

                  (b) On a continuing basis, the Company will make, execute,
acknowledge, deliver, file and record, as the case may be, in the proper filing
and recording places in any jurisdiction, including, without limitation, the
jurisdictions indicated on Schedule C, attached hereto, all such instruments,
and take all such action as may reasonably be deemed necessary or advisable, or
as reasonably requested by the Agent, to perfect the Security Interest granted
hereunder and otherwise to carry out the intent and purposes of this Agreement,
or for assuring and confirming to the Agent the grant or perfection of a
security interest in all the Intellectual Property.

                  (c) The Company hereby irrevocably appoints the Agent as the
Company's attorney-in-fact, with full authority in the place and stead of the
Company and in the name of the Company, from time to time in the Agent's
discretion, to take any action and to execute any instrument which the Agent may
deem necessary or advisable to accomplish the purposes of this Agreement,

                                       9

including the filing, in its sole discretion, of one or more financing or
continuation statements and amendments thereto, relative to any of the
Intellectual Property without the signature of the Company where permitted by
law.

            14. OTHER SECURITY. To the extent that the Obligations are now or
hereafter secured by property other than the Intellectual Property or by the
guarantee, endorsement or property of any other person, firm, corporation or
other entity, then the Agent shall have the right, in its sole discretion, to
pursue, relinquish, subordinate, modify or take any other action with respect
thereto, without in any way modifying or affecting any of the Secured Party's
rights and remedies hereunder.

            15. MISCELLANEOUS.

                  (a) No course of dealing between the Company, the Agent and
any Secured Party, nor any failure to exercise, nor any delay in exercising, on
the part of the Agent or any Secured Party, any right, power or privilege
hereunder or under the Debentures shall operate as a waiver thereof;

                                       10
<PAGE>

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.

                  (b) All of the rights and remedies of the Secured Party with
respect to the Intellectual Property, whether established hereby or by the
Debentures or by any other agreements, instruments or documents or by law shall
be cumulative and may be exercised singly or concurrently.

                  (c) This Agreement and the Security Agreement constitute the
entire agreement of the parties with respect to the subject matter hereof and is
intended to supersede all prior negotiations, understandings and agreements with
respect thereto. Except as specifically set forth in this Agreement, no
provision of this Agreement may be modified or amended except by a written
agreement specifically referring to this Agreement and signed by the parties
hereto.

                  (d) In the event that any provision of this Agreement is held
to be invalid, prohibited or unenforceable in any jurisdiction for any reason,
unless such provision is narrowed by judicial construction, this Agreement
shall, as to such jurisdiction, be construed as if such invalid, prohibited or
unenforceable provision had been more narrowly drawn so as not to be invalid,
prohibited or unenforceable. If, notwithstanding the foregoing, any provision of
this Agreement is held to be invalid, prohibited or unenforceable in any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective to
the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions of
this Agreement and without affecting the validity or enforceability of such
provision or the other provisions of this Agreement in any other jurisdiction.

                  (e) No waiver of any breach or default or any right under this
Agreement shall be considered valid unless in writing and signed by the party
giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

                  (f) This Agreement shall be binding upon and inure to the
benefit of each party hereto and its successors and assigns.

                  (g) Each party shall take such further action and execute and
deliver such further documents as may be necessary or appropriate in order to
carry out the provisions and purposes of this Agreement.

                  (h) This Agreement shall be construed in accordance with the
laws of the State of New York, except to the extent the validity, perfection or
enforcement of a security interest hereunder in respect of any particular
Intellectual Property which are governed by a jurisdiction other than the State
of New York in which case such law shall govern. Each of the parties hereto
irrevocably submit to the exclusive jurisdiction of any New York State or United
States Federal court sitting in New York county over any action or proceeding
arising out of or relating to this Agreement, and the parties hereto hereby
irrevocably agree that all claims in respect of such action or proceeding may be
heard and determined in such New York State or Federal court. The parties hereto
agree that a final judgment in any such action or proceeding shall be conclusive
and may be enforced in other jurisdictions by suit on the judgment or in any
other manner provided by law. The parties hereto further waive any objection to
venue in the State of New York and any objection to an action or proceeding in
the State of New York on the basis of forum non conveniens.

                  (i) EACH PARTY HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE
RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT
OF THIS AGREEMENT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING
OF ANY DISPUTES THAT MAY BE FILED IN ANY COURT AND

                                       11
<PAGE>

THAT RELATE TO THE SUBJECT MATER OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND
STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL
INDUCEMENT FOR EACH PARTY TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH PARTY
HAS RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH PARTY
WILL CONTINUE TO RELY ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH
PARTY FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS
LEGAL COUNSEL, AND THAT SUCH PARTY HAS KNOWINGLY AND VOLUNTARILY WAIVES ITS
RIGHTS TO A JURY TRIAL FOLLOWING SUCH CONSULTATION. THIS WAIVER IS IRREVOCABLE,
MEANING THAT, NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IT MAY NOT BE
MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS AND SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN
CONSENT TO A TRIAL BY THE COURT.

                  (j) This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.
