Collateral against prior parties or to protect, perfect, preserve or maintain
any security interest given to secure any Pledged Collateral.

          8.2  Reasonable Care.  Pledgee and GCC each shall be deemed to have
               ---------------
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if it deals with the Pledged Collateral in such
manner as Pledgee or GCC deals with similar property for its own account.

          8.3  Accountability.  Pledgee and GCC each shall be accountable only
               --------------
for any amounts it actually receives, and it shall not be liable to Pledgor for
any act or failure to act.

     9.   Default.  The occurrence of any one or more of the following shall
          -------

<PAGE>

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

     secured by the security interest granted under this Agreement.

               (d) Receive all amounts payable in respect to the Pledged
     Collateral otherwise payable to Pledgor; transfer all or any part of the

     or not transferred into the name of Pledgee or GCC) and give all consents,
     waivers and ratifications in respect of all or any part of the Pledged
     Collateral and exercise all rights, options and privileges and otherwise
     act with respect to the Pledged Collateral as thought Pledgee were the
     owner thereof (Pledgor hereby irrevocably constituting Pledgee the proxy
     and attorney-in-fact of Pledgor, with full power of substitution to do so).

               (e) At any time or from time to time to sell, assign and deliver,
     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
     performance, advertisement or notice of intention to sell, or of the time
     or place of sale, or adjournment thereof, or redeem or otherwise (all of
     which are hereby waived by 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

                                      -6-
<PAGE>

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 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 prior
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.

                                      -7-

          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
               --------

               -------------
this Agreement shall be governed by the laws, without regard to the laws as to

               ----------------
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.

to give any notice, demand or request with respect to this Agreement, each such
communication shall be in writing and shall be given by personal service or
mailed by Certified Mail, postage prepaid, return receipt requested, addressed
as set forth in the first paragraph of this Agreement.  Such communications sent
shall be effectively given when they are received by the addressee thereof, but
if sent by Certified Mail, they shall be effectively given three (3) days after

change their respective address for such communications by giving notice to the
other in conformity with this Section.

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

                                      -8-
<PAGE>

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,
and this Agreement shall be construed in all respects as if any invalid or
unenforceable provision were omitted.

          13.9  Further Action.  The Pledgor agrees to perform any further acts
                --------------
