               ---------------

               (a) Exercise any and all rights and remedies which Pledgee may
     have under or with respect to the Loan Agreement, the Note and this
     Agreement, all to the extent and in such order as Pledgee may determine in
     its sole discretion.

               (b) Exercise any and all rights and remedies available to a

     or grant options to purchase, all or any part of the Pledged Collateral, or
     any interest therein, at public or private sale, without demand of

     or place of sale, or adjournment thereof, or redeem or otherwise (all of
     which are hereby waived by

                                      -6-
<PAGE>

     Pledgor), for cash, on credit or for other property, for immediate for
     future delivery without any assumption of credit risk, and for such price
     or prices and on such terms as Pledgee in its absolute discretion may
     determine, provided that notice of the time and place of any such sale
     shall be given to Pledgor in the manner provided in this Section 10.2 of
     this Agreement. Pledgor hereby waives and releases to the fullest extent
     permitted by law any right or equity of redemption with respect to the
     Pledged Collateral, whether before or after sale under this Agreement, and
     all rights, if any, of marshaling the Pledged Collateral and any other
     security for any Obligations or otherwise. At any such sale, unless
     prohibited by applicable law, Pledgee may bid for and purchase all or any
     part of the Pledged Collateral so sold free from any such right or equity
     of redemption. Pledgee and GCC shall not be liable for failure to collect
     or realize upon any or all of the Pledged Collateral or for any delay in so
     doing nor shall Pledgee and GCC be under any obligation to take any action
     whatsoever with regard thereto.

          10.2 Notice of Sale.  Pledgee's notice of the time and place of public
               --------------
sale of the Pledged Collateral, or the time on or after which a private sale or
other disposition of the Pledged Collateral will be made, is reasonable if given
to Pledgor in the manner for giving notices under this Agreement at least five
(5) days before the public or private sale.

          10.3 Pledgor's Duties.  Pledgor must assemble all records relating to
               ----------------
the Pledged Collateral and make them available to Pledgee as Pledgee directs,
and execute all documents and instruments on Pledgee's request that Pledgee
considers necessary or advisable to exercise its rights under this Agreement.

     11.  Registration.  If at any time when Pledgee shall determine to exercise
          ------------
its right to sell all or any Securities, such Securities or the part thereof to
be sold shall not, for any reason whatsoever, be effectively registered under
the Securities Act of 1933, as then in effect, Pledgee may, in its sole
discretion, sell any such Securities by private sale in such manner and under
such circumstances as Pledgee reasonably may deem necessary or advisable in
order that such sale may legally be effected without such registration, provided
that notice of the time and place of any such sale shall be given to Pledgor in
the manner provided in Section 10.2 of this Agreement and that such sale shall
be conducted in a commercially reasonable manner.  Without limiting the
generality of the foregoing, in any such event, Pledgee, in its sole discretion,
may proceed to make such private sale notwithstanding that a registration
statement for the purpose of registering such Securities or part thereof shall
have been filed under such Securities Act, may approach and negotiate with a
single possible purchaser to effect such sale, and may restrict such sale to a
purchaser who will represent and agree that such purchaser is purchasing for its
own account, for investment, and not with a view to the distribution or sale of
such Securities or any part thereof. In the event of any

                                      -7-
<PAGE>

such sale, Pledgee shall incur no responsibility or liability for selling all or
any Securities at a price which Pledgee may in good faith deem reasonable under
the circumstances, notwithstanding the possibility that a substantially higher
price might be realized if such Securities were registered as aforesaid.

     12.  Termination.  When all Obligations have been irrevocably paid,
          -----------
performed and discharged in full, this Agreement shall terminate, and Pledgee,
at the request and expense of Pledgor, promptly will execute and deliver to
Pledgor a proper instrument or instruments acknowledging the satisfaction and
termination of this Agreement, and, subject to satisfaction of all obligations
of Pledgor pursuant to the Prior Pledge, will assign, transfer and deliver to
Pledgor (without recourse and without any representation or warranty) such of
the Pledged Collateral as may be in the possession of Pledgee or GCC as its
bailee and has not theretofore been sold or otherwise applied or released
pursuant to this Agreement.

     13.  Other Provisions.
          ----------------

          13.1 Expenses.  The Pledgor agrees to pay all attorneys' fees and all
               --------
other costs and expenses which may be incurred by Pledgee in the enforcement or
collection of this Agreement whether or not suit is filed.

          13.2 Interest.  All amounts required to be paid to Pledgee by the
               --------
Pledgor pursuant to the provisions of this Agreement shall bear interest from
the date upon which such amounts are due to the date of payment thereof at the
highest rate permitted by law.  All payments of such amounts by the Pledgor
shall include any such accrued interest.

          13.3 Governing Law.  The validity, construction and performance of
               -------------
this Agreement shall be governed by the laws, without regard to the laws as to
choice or conflict of laws, of the State of California.

          13.4 Entire Agreement.  This Agreement embodies the entire agreement
               ----------------
and understanding between Pledgee and the Pledgor pertaining to the subject
matter of this Agreement, and supersedes all prior agreements, understandings,
negotiations, representations and discussions, whether verbal or written, of
such parties, pertaining to that subject matter.

          13.5 Assignment; Binding Effect.  Neither this Agreement nor any
               --------------------------
rights or obligations under this Agreement may be assigned by the Pledgor
without the prior written consent of Pledgee. Subject to the foregoing, the
provisions of this Agreement shall bind and inure to the benefit of Pledgee and
the Pledgor and their respective heirs, executors, personal representatives,
successors and assigns.

                                      -8-

to give any notice, demand or request with respect to this Agreement, each such

modified or supplemented except by a writing duly executed by the Pledgor and a
duly authorized officer of Pledgee.  No provision of this Agreement or right of
Pledgee under this Agreement can be waived except by a writing duly executed by
a duly authorized officer of Pledgee.  No waiver by Pledgee of a Default under
this Agreement shall be construed as a waiver of any subsequent or different
Default, and no forbearance by Pledgee to seek a remedy for any Default by
Pledgor shall be construed as a waiver of any right or remedy with respect to
such Default.

          13.8 Severability.  The invalidity or unenforceability of any
               ------------
particular provision of this Agreement shall not affect the other provisions,
