            (iv)  other than as set forth in Schedule B, the Company is the
                  exclusive owner of the entire and unencumbered right, title
                  and interest in and to such Intellectual Property and no claim
                  has been made that the use of such Intellectual Property

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 Notes, 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) The Secured Party shall have the right 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.

      (b) The Secured Party shall have the right 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

                                      C-8
<PAGE>

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 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, the Company will be liable for the deficiency, together
with interest thereon, at the rate of 15% 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
Notes. Until so paid, any fees payable hereunder shall be added to the principal
amount of the Notes 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 Notes 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 Notes, the Warrants or any agreement entered into in connection with the
foregoing, or any portion hereof or thereof; (b) any

                                      C-9
<PAGE>

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 Notes, 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,
notice of protest, demand, notice of nonpayment and demand for performance. In
the event that at any time any transfer of any Intellectual Property or any
payment received by the 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 Notes 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 Secured Party, and does hereby make,
constitute and appoint it, and its respective officers, agents, successors or

      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 Secured Party 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 and the Secured Party, nor
any failure to exercise, nor any delay in exercising, on the part of the Secured
Party, any right, power or privilege hereunder or under the Notes 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.

      (b) All of the rights and remedies of the Secured Party with respect to
the Intellectual Property, whether established hereby or by the Notes 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 Manhattan 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 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

                                      C-13
<PAGE>

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 ALREADY 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 A 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.
