          (a)  The Company (either itself or through licensees) will not do any
act, or omit to do any act, whereby any material Patent may become forfeited,
abandoned or dedicated to the public.

          (b)  The Company (either itself or through licensees) will not do any
act that knowingly uses any material Intellectual Property to infringe the
intellectual property rights of any other Person.

          (c)  The Company will notify the Holder immediately if it knows, or
has reason to know, that any application or registration relating to any
material Intellectual Property may become forfeited, abandoned or dedicated to
the public, or of any adverse determination or development (including, without

proceeding in the United States Patent and Trademark Office, the United States
Copyright Office or any court or tribunal in any country) regarding the
Company's ownership of, or the validity of, any material Intellectual Property
or the Company's right to register the same or to own and maintain the same.

          (d)  Whenever such Company, either by itself or through any agent,
employee, licensee or designee, shall file an application for the registration
of any Intellectual Property with the United States Patent and Trademark Office,
the United States Copyright Office or any similar office or agency in any other
country or any political subdivision thereof, the Company shall report such
filing to the Holder within five Business Days after the last day of the fiscal

          In the event that any material Intellectual Property is infringed,
misappropriated or diluted by a third party, the Company shall (i) take such
actions as the Company shall reasonably deem appropriate under the circumstances
to protect such Intellectual Property and (ii) if such Intellectual Property is
of material economic value, promptly notify the Holder after it learns thereof

<PAGE>

                                                                               7

          (b)  of the occurrence of any other event which could reasonably be
expected to have a material adverse effect on the aggregate value of the
Collateral or on the security interests created hereby.

          5.   Remedies. If an Event of Default shall occur and be continuing,
               --------

it in this Agreement and in any other instrument or agreement securing,
evidencing or relating to the Obligations, all rights and remedies of a secured
party under the Code.

               ---------------------------------
law, the Company authorizes the Holder to file or record financing statements
and other filing or recording documents or instruments with respect to the
Collateral without the signature of the Company in such form and in such offices
as the Holder determines appropriate to perfect the security interests of the
Holder under this Agreement. The Company authorizes the Holder to use the
collateral description "all personal property" in any such financing statements.

          7.   Severability. Any provision of this Agreement which is prohibited
               ------------
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          8.   Amendments in Writing. 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 Company and the Holder.

               ---------------------------------------------------
shall not by any act (except by a written instrument pursuant to Section 8),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Event of Default. No failure to
exercise, nor any delay in exercising, on the part of the Holder, any right,
power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Holder of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the Holder
would otherwise have on any future occasion. The rights and remedies herein
provided are cumulative, may be exercised singly or concurrently and are not
exclusive of any other rights or remedies provided by law.

          10.  Enforcement Expenses; Indemnification. (a) The Company agrees to

with any of the transactions contemplated by this Agreement.
