learning of the existence of any actual or threatened infringement thereof, upon
twenty (20) days prior written notice to Grantor, Greyrock shall have the right,
but shall in no way be obligated to, bring suit or take any other action, in its
own name or in Grantor's name, to enforce or preserve Greyrock's or Grantor's
fights in the Copyrights. Grantor shall at the request of Greyrock and at

reimburse and indemnify Greyrock for all costs and expenses incurred in the
exercise of Greyrock's or Grantor's rights under this Section 8.

     8.   No Waiver. No course of dealing between Grantor and Greyrock, nor any
          ---------
failure to exercise nor any delay in exercising, on the part of Greyrock, any
right, power, or privilege under this Agreement or under the Loan Agreement or
any other agreement, shall operate as a waiver. No single or partial exercise of
any fight, power, or privilege under this Agreement or under the Loan Agreement

of such right, power, or privilege or the exercise of any other right, power, or
privilege by Greyrock.

     9.   Rights Are Cumulative. All of Greyrock's rights and remedies with
          ---------------------

office. Greyrock may record this Agreement, an abstract thereof, or any other
document describing Greyrock's interest in the Copyrights with the United States
Copyright Office, at the expense of Grantor.

     11.  Indemnity. Grantor shall indemnify, and hold harmless Greyrock and
          ---------
Greyrock's pursuant to Section 5.10 of the Loan Agreement.

                                      -3-
<PAGE>

     12.   Severability. The provisions of this Agreement are severable. If any
           ------------
provision of this Agreement is held invalid or unenforceable in whole or in part
in any jurisdiction, then such invalidity or unenforcebility shall affect only
such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other jurisdiction, or any
other provision of this Agreement in any jurisdiction.

     13.   Amendments; Entire Agreement. This Agreement is subject to
           ----------------------------
modification only by a writing signed by the parties, except as provided in
Section 5 of this Agreement. To the extent that any provision of this Agreement
conflicts with any provision of the Loan Agreement, the provision giving
Greyrock greater rights or remedies shall govern, it being understood that the
purpose of this Agreement is to add to, and not detract from, the rights granted
to Greyrock under the Loan Agreement. This Agreement, the Loan Agreement, and
the documents relating thereto comprise the entire agreement of the parties with
respect to the matters addressed in this Agreement.

     14.   Further Assurances. At Greyrock's request, Grantor shall execute and
           ------------------
deliver to Greyrock any further instruments or documentation, and perform any
acts, that may be reasonably necessary or appropriate to implement this
Agreement, the Loan Agreement or any other agreement, and the documents relating
thereto, including without limitation any instrument or documentation reasonably
necessary or appropriate to create, maintain, perfect, or effectuate Greyrock's
security interests in the Copyrights or other Collateral.

     15.   Release. At such time as Grantor shall completely satisfy all of the
           -------
Obligations and the Loan Agreement shall be terminated, Greyrock shall execute
and deliver to Grantor all assignments and other instruments as may be
reasonably necessary or proper to terminate Greyrock's security interest in the
Copyrights, subject to any disposition of the Copyrights which may have been
made by Greyrock pursuant to this Agreement. For the purpose of this Agreement,
the Obligations shall be deemed to continue if Grantor enters into any
bankruptcy or similar proceeding at a time when any amount paid to Greyrock
could be ordered to be repaid as a preference or pursuant to a similar theory,
and shall continue until it is finally determined that no such repayment can be
ordered.

     16.   True and Lawful Attorney. Grantor hereby appoints Greyrock as

in the Copyrights, for filing with the United States Copyright Office; (b)

Agreement; and (c) following an Event of Default (as defined in the Loan
Agreement) execute any assignments, notices or transfer documents for purposes
of transferring title or right to receive any of the Copyrights or other
Collateral to any person, including without limitation Greyrock.

           -------------
the rights and obligations of the parties shall be governed by the laws of the
State of California, excluding its conflict of law rules to the extent such
rules would apply the law of another jurisdiction, and the United States.

          In order to induce Lender to enter into the Loan Agreement and make
the Loan to Pledgor and to secure the Obligations (as defined below), Pledgor is
pledging to Lender, all or a portion of the issued and outstanding shares of the
capital stock of the Pledged Affiliates as set forth on Schedule 1 hereto, all

request.

     (c) In the event Pledgor acquires any additional shares of capital stock of

with, result in a material breach of or constitute (with due notice and/or lapse
of time) a material default under any such indenture, agreement or other
instrument;

      (x)  there are no pending legal or governmental proceedings to which

listed on Schedule 1.

     5. Voting Rights: Dividends; etc.  (a) Unless and until an Event of Default
        -----------------------------
shall have occurred and be continuing:

          (i) Pledgor shall be entitled to exercise any and all voting and/or
consensual rights and powers accruing to the owner of the Pledged Securities or
any part thereof for any purpose not inconsistent with the terms hereof and of
the Loan Agreement.

          (ii) Any dividends or distributions of any kind whatsoever received by
Pledgor, whether resulting from a subdivision, combination, or reclassification
of the outstanding capital stock of the Pledged Affiliates or received in
exchange for the Pledged Securities or any part thereof or as a result of any
merger, consolidation, acquisition, or other exchange of assets to which the
Pledged Affiliates may be a party, or otherwise, shall be and become part of the
Pledged Securities pledged hereunder and shall immediately be delivered to
Lender to be held subject to the terms of this Pledge Agreement.

all rights of Pledgor to (i) exercise the voting and/or consensual rights and
powers which it is entitled to exercise pursuant to Section 5(a)(i) hereof and
(ii) receive and retain dividends and distributions which Pledgor would be
entitled to receive and retain pursuant to Section 5(a)(ii), if any, shall cease
and all such rights shall thereupon become vested in Lender who shall have the
sole and exclusive right and authority to exercise such voting and/or consensual
rights; provided, however, that to the extent any governmental consents or
filings are required for the exercise by Lender of any of the foregoing rights
and powers, Lender shall refrain from exercising such rights or powers until the
making of such required filings, the receipt of such consents and the expiration
of all related waiting periods.

     6. Remedies Upon Default. (a) If an Event of Default shall have occurred
        ---------------------
and be continuing, Lender may, subject to applicable securities laws, sell the
Pledged Securities, or any part thereof, at public or private sale or at any
broker's board or on any securities exchange, for cash, upon credit or for
future delivery as Lender shall deem appropriate subject to the terms hereof or
as otherwise provided in the California Uniform Commercial Code. Lender shall be
authorized at any such sale (if it deems it advisable to do so) to restrict the
prospective bidders or purchasers to persons who will represent and agree that
they are purchasing the Pledged Securities for their own account and not with a
view to the distribution or sale thereof, and upon consummation of any such sale
Lender shall have the right to assign, transfer, and deliver to the purchaser or
purchasers thereof the Pledged Securities so sold. Each such purchaser at any
such sale shall hold the property sold absolutely, free from any claim or right
on the part of Pledgor.

     (b) The Lender shall give Pledgor seven (7) days' written notice of
Lender's intention to make any such public or private sale, or sale at any
broker's board or on any such securities exchange, or of any other disposition
of the Pledged Securities contemplated by Section 6(a). Such notice, in the case
of public sale, shall state the time and place for such sale and, in the case of
sale at a broker's board or on a securities exchange, shall state the board or
exchange at which such sale is to be made and the day on which the Pledged
Securities, or portion thereof, will first be offered for sale at such board or
exchange. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as Lender may fix and shall
state in the notice of such sale. At any such sale, the Pledged Securities, or
portion thereof, to be sold may be sold in one lot as an entirety or in separate
parcels, as Lender may (in its sole and absolute discretion) determine. Lender
shall not be obligated to make any sale of the Pledged Securities if it shall
determine not to do so, regardless of the fact that notice of sale of the
Pledged Securities may have been given. Lender may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for
sale, and such sale may, without further notice, be made at the time and place
to which the same was so

                                      -4-

adjourned. In case the sale of all or any part of the Pledged Securities is made
on credit or for future delivery, the Pledged Securities so sold shall be
retained by Lender until the sale price is paid by the purchaser or purchasers
thereof, but Lender shall not incur any liability in case any such purchaser or
purchasers shall fail to take up and pay for the Pledged Securities so sold and,
in case of any such failure, such Pledged Securities may be sold again upon like
notice. At any sale or sales made pursuant to this Section 6, Lender may bid for
or purchase, free from any claim or right of whatever kind, including any equity
of redemption, of Pledgor, any such demand, notice, claim, right or equity being
hereby expressly waived and released, any or all of the Pledged Securities
offered for sale, and may make any payment on the account thereof by using any
claim for moneys then due and payable to Lender by Pledgor or the Pledged
Affiliates as a credit against the purchase price; and Lender, upon compliance
with the terms of sale, may hold, retain and dispose of the Pledged Securities
without further accountability therefor to Pledgor or any third party. Lender
shall in any such sale make no representations or warranties with respect to the
Pledged Securities or any part thereof, and Lender shall not be chargeable with
any of the obligations or liabilities of Pledgor with respect thereto. Pledgor
hereby agrees (i) it will indemnify and hold Lender harmless from and against
any and all claims with respect to the Pledged Securities asserted before the
taking of actual possession or control of the Pledged Securities by Lender
pursuant to this Pledge Agreement or arising out of any act of, or omission to
act on the part of, any party other than Lender prior to such taking of actual
possession or control by Lender, or arising out of any act on the part of
Pledgor or its agents before or after the commencement of such actual possession
or control by Lender; and (ii) Lender shall have no liability or obligation
arising out of any such claim. As an alternative to exercising the power of sale
herein conferred upon it, Lender may proceed by a suit or suits at law or in
equity to foreclose this Pledge Agreement and to sell the Pledged Securities, or
any portion thereof, pursuant to a judgment or decree of a court or courts
having competent jurisdiction.

     7. Application of Proceeds of Sale and Cash.  The proceeds of any sale of
        ----------------------------------------
the Pledged Securities sold pursuant to Section 6 hereof shall be applied by
Lender (in such order as Lender shall in its sole discretion determine) to the
payment in full of the Obligations and the payment of costs incurred by Lender
while enforcing its rights pursuant to this Pledge Agreement.

     8. Lender Appointed Attorney-in-Fact.  Upon the occurrence of an Event of
        ---------------------------------
Default and during the continuance of an Event of Default, Pledgor hereby
appoints Lender its attorney-in-fact for the purpose of carrying out the
provisions of this Pledge Agreement and the pledge of the Pledged Securities
hereunder and taking any action and executing any instrument which Lender may
deem necessary or advisable to accomplish the purposes hereof, which appointment
is irrevocable and coupled with an interest. Without limiting the generality of
the foregoing, Lender shall have the right and power to receive, endorse, and
collect all checks and other orders for the payment of money made payable to
Pledgor representing any dividend or other distribution payable in respect of
the Pledged Securities or any part thereof and to give full discharge for the
same.

                                      -5-

     9. Securities Act, etc. In view of the position of Pledgor in relation to
        -------------------
the Pledged Securities, or because of other present or future circumstances, a
question may arise under the Securities Act of 1933, as amended, as now or
hereafter in effect, or any similar statute hereafter enacted analogous in
purpose or effect (such Act and any such similar statute as from time to time in
effect being hereinafter called the "Federal Securities Laws"), with respect to
any disposition of the Pledged Securities permitted hereunder. Pledgor
understands that compliance with the Federal Securities Laws may very strictly
limit the course of conduct of Lender if Lender were to attempt to dispose of
all or any part of the Pledged Securities, and may also limit the extent to
which or the manner in which any subsequent transferee of any Pledged Securities
may dispose of the same. Similarly, there may be other legal restrictions or
limitations affecting Lender in any attempt to dispose of all or any part of the
Pledged Securities under applicable "Blue Sky" or other state securities laws,
or similar laws analogous in purpose or effect. Under applicable law, in the
absence of an agreement to the contrary, Lender may be held to have certain
general duties and obligations to Pledgor to make some effort towards obtaining
a fair price even though the Obligations may be discharged or reduced by the
proceeds of a sale at a lesser price. To the maximum extent permitted by
applicable law, Pledgor hereby agrees that Lender shall not have any such
general duty or obligation to it, and Pledgor will not attempt to hold Lender
responsible for selling all or any part of the Pledged Securities at an
inadequate price, even if Lender shall accept the first offer received or does
not approach more than one possible purchaser. Without limiting the generality
of the foregoing, the provisions of this Section 9 would apply if, for example,
Lender were to place all or any part of the Pledged Securities for private
placement by an investment banking firm, or if such investment banking firm
purchased all or any part of the Pledged Securities for its own account, or if
Lender placed all or any part of the Pledged Securities privately with a
purchaser or purchasers.

     10. Continuation and Reinstatement. Pledgor further agrees that its pledge
         ------------------------------
hereunder shall continue to be effective or be reinstated, as the case may be,
if at any time payment, or any part thereof, of principal of or interest on any
Obligation is rescinded or must otherwise be restored by Lender upon the
bankruptcy or reorganization of Pledgor or otherwise.

     11. Termination. The pledge hereunder shall terminate when all of the
         -----------
obligations of Pledgor under the Loan Agreement or under any other instruments
or documents delivered by Pledgor in connection with the Loan Agreement shall
have been fully paid and performed and the Loan Agreement shall have been
terminated. At such time Lender shall, at the sole cost and expense of Pledgor,
assign and deliver to Pledgor, or to such person or persons as Pledgor shall
designate, against receipt, such of the Pledged Securities (if any) as shall not
have been sold or otherwise applied by Lender pursuant to the terms hereof and
shall still be held by it hereunder, together with appropriate instruments of
reassignment and release. Any such reassignment shall be without recourse upon
or warranty by Lender (except as to acts of Lender or persons claiming through
Lender).

     12. Further Assurances. Pledgor, at its own expense, will execute and
         ------------------
deliver, from time to time, any and all further, or other, instruments, and
perform such acts, as Lender may reasonably request to effect the purposes of
this Pledge Agreement and to secure to Lender, the benefits of all rights,
authorities, and remedies conferred upon Lender by the terms of this Pledge
Agreement.

     13. Notices. Notices and other communication provided for herein shall be
         -------
in writing and shall be governed by the notice provisions of the Loan Agreement.

     14. Non-Waiver of Rights and Remedies. No delay or failure on the part of
         ---------------------------------
Lender in the exercise of any right or remedy shall operate as a waiver thereof,
no single or partial exercise by Lender of any right or remedy shall preclude
other or further exercise thereof or the exercise of any other right or remedy
and no course of dealing between the parties shall operate as a waiver of any
right or remedy of Lender.

     15. CHOICE OF LAW. THIS AGREEMENT AND ANY INSTRUMENT OR AGREEMENT REQUIRED
         -------------
HEREUNDER SHALL BE DEEMED TO BE MADE UNDER, SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA
WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

     16. Severability.  This Pledge Agreement shall be interpreted in such
         ------------
manner as to be effective and valid under applicable law, but if any provision
of this Pledge Agreement shall be prohibited by or invalidated under applicable
law, such provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Pledge Agreement and the parties hereto agree to
negotiate in good faith a provision to replace the ineffective provision, such
provision to be as similar in effect and intent as the ineffective provision as
permissible.

     17. Amendments. This Pledge Agreement may not be amended except by a
         ----------
writing signed by the parties hereto.

     18. Successors and Assigns. This Pledge Agreement shall be binding upon and
         ----------------------
inure to the benefit of the parties hereto and their respective successors and
assigns.

     19. Counterparts. This Pledge Agreement may be executed in any number of
         ------------
counterparts, each of which when so executed and delivered shall constitute an
original for all purposes, but all such counterparts taken together shall
constitute the same instrument.

                                      -7-

     IN WITNESS WHEREOF, the parties hereto have caused this Pledge Agreement to
be duly executed as of the day and year first above written.
