shall be promptly delivered by the Pledgors to the Escrow Agent, as the Secured
Party's sole and exclusive agent, who shall hold such certificates or
instruments and the shares represented thereby for the sole and exclusive

distributions, excluding cash) at any time received or held by the Pledgors

the Escrow Agent in the same form as so received or held, with any necessary

the sole right to exercise such voting or other consensual rights and to receive
and retain such dividends and distributions, excluding cash. The Pledgors shall
execute and deliver (or cause to be executed and delivered) to the Secured Party
all such proxies and other instruments as the Secured Party may reasonably
request for the purpose of enabling the Secured Party to exercise the voting and
other rights which it is entitled to exercise and to receive the dividends and

(d) This Agreement, and the delivery to the Escrow Agent of the Pledged Shares

necessary to achieve such perfection (as defined in the Uniform Commercial Code)
have been duly taken;

     7. Further Assurances.

(a) The Pledgors agree that from time to time, at the expense of the Pledgors,
the Pledgors will promptly execute and deliver all further instruments and
documents, and take all further action that may be necessary or reasonably
desirable, or that the Secured Party may request, in order to perfect and
protect any security interest granted or purported to be granted hereby to the
Secured Party or to enable the Secured Party to exercise and enforce its rights
and remedies hereunder with respect to any Collateral. Without limiting the
generality of the foregoing, each Pledgor will: (i) at the request of the
Secured Party, mark conspicuously each of its records pertaining to the
Collateral with a legend, in form and substance reasonably satisfactory to
Secured Party, indicating that such Collateral is subject to the security
interest granted hereby; (ii) execute and file such financing or continuation
statements, or amendments thereto, and such other instruments or notices, as may
be necessary or reasonably desirable, or as the Secured Party may request, in
order to perfect and preserve the security interests granted or purported to be
granted hereby; (iii) allow inspection of the Collateral by the Secured Party or
persons designated by the Secured Party; and (iv) appear in and defend any
action or proceeding that may affect the Pledgor's title to or the Secured
Party's security interest in the Collateral, except for any litigation at the
cost of the Secured Party.

(b) The Pledgors hereby authorize the Secured Party to file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the Collateral without the signature of any Pledgor where permitted
by law. A carbon, photographic, or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

(c) Each Pledgor will furnish to the Secured Party, upon the request of the
Secured Party: (i) a certificate executed by an authorized officer of such
Pledgor, and dated as of the date of delivery to Secured Party, itemizing in
such detail as the Secured Party may request, the Collateral which, as of the
date of such certificate, has been delivered to the Secured Party by such
Pledgor pursuant to the provisions of this Agreement; and (ii) such statements
and schedules further identifying and describing the Collateral and such other
reports in connection with the Collateral as Secured Party may request.

     8. Covenants of Pledgors. Each Pledgor shall:

(a) Perform each and every covenant in the Stock Purchase Agreement and related
agreements as applicable to the Pledgor; and

(b) At all times keep at least one complete set of its records concerning
substantially all of the Collateral at such the Pledgor's Primary Address as set
forth in Schedule A hereto, and not change the location of such Primary Address
or such records without giving the Secured Party at least thirty (30) days prior
written notice thereof.


                                       6

     9. Remedies. In the event that the Secured Party becomes entitled to
payment pursuant to Section 10 of the Stock Purchase Agreement and the Pledgors
shall fail to remit such payment, then Secured Party shall be entitled to
exercise the following rights and remedies:

(a) the Secured Party may exercise in respect of the Collateral, in addition to
other rights and remedies provided for herein or otherwise available to it, all
the rights and remedies of a secured party on default under the Code
(irrespective of whether the Code applies to the affected items of Collateral),
and the Secured Party may also without notice (except as specified below) sell
the Collateral or any part thereof in one or more parcels at public or private
sale, at any exchange, broker's board or at any of the Secured Party's offices
or elsewhere, for cash, on credit or for future delivery, at such time or times
and at such price or prices and upon such other terms as the Secured Party may
deem commercially reasonable, irrespective of the impact of any such sales on
the market price of the Collateral. To the maximum extent permitted by
applicable law, the Secured Party may be the purchaser of any or all of the
Collateral at any such sale and shall be entitled, for the purpose of bidding
and making settlement or payment of the purchase price for all or any portion of
the Collateral sold at any such public sale, to use and apply all or any part of
the Secured Obligations as a credit on account of the purchase price of any
Collateral payable at such sale. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of any
Pledgor, and each Pledgor hereby waives (to the extent permitted by law) all
rights of redemption, stay, or appraisal that it now has or may at any time in
the future have under any rule of law or statute now existing or hereafter
enacted. Each Pledgor agrees that, to the extent notice of sale shall be
required by law, at least ten (10) calendar days notice to such Pledgor of the
time and place of any public sale or the time after which a private sale is to
be made shall constitute reasonable notification. The Secured Party shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. The Secured Party may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned. To the maximum extent permitted by law, each Pledgor hereby waives
any claims against the Secured Party arising because the price at which any
Collateral may have been sold at such a private sale was less than the price
that might have been obtained at a public sale, even if the Secured Party
accepts the first offer received and does not offer such Collateral to more than
one offeree.

(b) Each Pledgor hereby agrees that any sale or other disposition of the
Collateral conducted in conformity with reasonable commercial practices of
banks, insurance companies, or other financial institutions in California in
disposing of property similar to the Collateral shall be deemed to be
commercially reasonable.

(c) Each Pledgor hereby acknowledges that the sale by the Secured Party of any
Collateral pursuant to the terms hereof in compliance with the Securities Act of
1933 as now in effect or as hereafter amended, or any similar statute hereafter
adopted with similar purpose or effect (the "Securities Act"), as well as
applicable "Blue Sky" laws or other state securities laws may require strict
limitations as to the manner in which the Secured Party or any subsequent
transferee of the Collateral may dispose thereof. Each Pledgor acknowledges and
agrees that in order to protect the Secured Party's interest it may be necessary
to sell the Collateral at a


                                       7
<PAGE>   8

price less than the maximum price attainable if a sale were delayed or were made
in another manner, such as a public offering under the Securities Act. The
Pledgors have no objection to sale in such a manner and agrees that the Secured
Party shall have no obligation to obtain the maximum possible price for the
Collateral. Without limiting the generality of the foregoing, the Pledgor agrees
that, in the event that the Secured Party becomes entitled to payment under
Section 10 of the Stock Purchase Agreement, the Secured Party may, subject to
applicable law, from time to time attempt to sell all or any part of the
Collateral by a private placement, restricting the bidders and prospective
purchasers to those who will represent and agree that they are purchasing for
investment only and not for distribution. In so doing, the Secured Party may
solicit offers to buy the Collateral or any part thereof for cash, from a
limited number of investors deemed by the Secured Party, in its reasonable
judgment, to be institutional investors or other responsible parties who might
be interested in purchasing the Collateral. If the Secured Party shall solicit
such offers, then the acceptance by the Secured Party of one of the offers shall
be deemed to be a commercially reasonable method of disposition of the
Collateral.

(d) If the Secured Party shall determine to exercise its right to sell all or
any portion of the Collateral pursuant to this Section, each Pledgor agrees
that, upon request of the Secured Party, such Pledgor will, at its own expense:

      (i) use its best efforts to execute and deliver all such instruments and
      documents, and to do or cause to be done all such other acts and things,
      as may be necessary or, in the reasonable opinion of the Secured Party,
      advisable to register such Collateral under the provisions of the
      Securities Act, and to cause the registration statement relating thereto
      to become effective and to remain effective for such period as
      prospectuses are required by law to be furnished, and to make all
      amendments and supplements thereto and to the related prospectuses which,
      in the opinion of the Secured Party, are necessary or advisable, all in
      conformity with the requirements of the Securities Act and the rules and
      regulations of the Securities and Exchange Commission applicable thereto;

      (ii) use its best efforts to qualify the Collateral under the state
      securities laws or "Blue Sky" laws and to obtain all necessary
      governmental approvals for the sale of the Collateral, as requested by the
      Secured Party;

      (iii) execute and deliver to any person, entity or governmental authority
      as the Secured Party may choose, any and all documents and writings which,
      in the Secured Party's reasonable judgment, may be necessary or
      appropriate for approval, or be required by, any regulatory authority
      located in any city, county, state or country where the Pledgor or the
      issuers engage in business, in order to transfer or to more effectively
      transfer the Pledged Shares or otherwise enforce the Secured Party's
      rights hereunder; and

      (iv) do or cause to be done all such other acts and things as may be
      necessary to make such sale of the Collateral or any part thereof valid
      and binding and in compliance with applicable law.


                                       8
<PAGE>   9

The Pledgors acknowledge that there is no adequate remedy at law for failure by
it to comply with the provisions of this Section and that such failure would not
be adequately compensable in damages, and therefore agrees that its agreements
contained in this Section may be specifically enforced.

(e) EACH PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW: (i)
ANY CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME
SECURED PARTY DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS
SECTION; (ii) ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT IT NOW HAS OR
MAY AT ANY TIME IN THE FUTURE HAVE UNDER ANY RULE OF LAW OR STATUTE NOW EXISTING
OR HEREAFTER ENACTED; AND (iii) EXCEPT AS SET FORTH IN SUBSECTION(a) OF THIS
SECTION, ANY REQUIREMENT OF NOTICE, DEMAND, OR ADVERTISEMENT FOR SALE.

     10. Duties of Secured Party. The powers conferred on the Secured Party
hereunder are solely to protect its interests in the Collateral and shall not
impose on it any duty to exercise such powers. Except as provided in Section
9-207 of the Code, the Secured Party shall have no duty with respect to the
Collateral or any responsibility for taking any necessary steps to preserve
rights against any other persons with respect to any Collateral.

     11. CHOICE OF LAW AND VENUE. THE VALIDITY OF THIS AGREEMENT, ITS
CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT, AND THE RIGHTS OF THE PARTIES
HERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF DELAWARE. THE PARTIES AGREE THAT ALL ACTIONS OR
PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT SHALL BE TRIED AND
LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED CALIFORNIA OR, AT THE
SOLE OPTION OF SECURED PARTY, IN ANY OTHER COURT IN WHICH SECURED PARTY SHALL
INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND WHICH HAS SUBJECT MATTER
JURISDICTION OVER THE MATTER IN CONTROVERSY. THE PLEDGORS AND SECURED PARTY EACH
WAIVES, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO
ASSERT THE DOCTRINE OF FORUM NON CONVENIENCE OR TO OBJECT TO VENUE TO THE EXTENT
ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION 11.

     12. Amendments; Etc. No amendment or waiver of any provision of this
Agreement nor consent to any departure by any Pledgor herefrom shall in any
event be effective unless the same shall be in writing and signed by Secured
Party, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given. No failure on the part of
the Secured Party to exercise, and no delay in exercising any right under this
Agreement, the Stock Purchase Agreement or any other related


                                       9
<PAGE>   10

agreement, or otherwise with respect to any of the Secured Obligations, shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right under this Agreement, the Stock Purchase Agreement or otherwise with
respect to any of the Secured Obligations preclude any other or further exercise
thereof or the exercise of any other right. The remedies provided for in this
Agreement or otherwise with respect to any of the Secured Obligations are
cumulative and not exclusive of any remedies provided by law.

     13. Notices. Unless otherwise specifically provided herein, any notice of

Obligations under the Stock Purchase Agreement; (ii) be binding upon each
Pledgor and such Pledgor's successors and assigns; and (iii) inure to the
benefit of the Secured Party and its successors, transferees, and assigns. Upon
the termination of the Secured Obligations, the security interests granted
herein to Secured Party shall automatically terminate and all rights to the
Collateral shall revert to the Pledgors, as applicable. Upon any such
termination, the Secured Party will, at each Pledgor's expense, execute and
deliver to each Pledgor such documents as such Pledgor shall reasonably request
to evidence such termination. Such documents shall be prepared by such Pledgor
and shall be in form and substance reasonably satisfactory to the Secured Party.

     15. Security Interest Absolute. To the maximum extent permitted by law, all
rights of the Secured Party, all security interests hereunder, and all
obligations of the Pledgors hereunder, shall be absolute and unconditional
irrespective of:

(a) any change in the time, manner, or place of payment of, or in any other term
of, all or any of the Secured Obligations, or any other amendment or waiver of
or any consent to any departure from the Stock Purchase Agreement or any other
agreement or instrument relating thereto to the extent such other amendment or
waiver does not affect the Secured Obligations;

(b) any other circumstances that might otherwise constitute a defense available
to, or a discharge of, the Pledgor.

To the maximum extent permitted by law, the Pledgors hereby waive any right to
require the Secured Party to: (A) proceed against or exhaust any security held
from the Pledgors; or (B) pursue any other remedy in the Secured Party's power
whatsoever.

absolute discretion, apply the proceeds of any or all of the Collateral to the
Secured Obligations in any order and in any manner it so reasonably elects. The
Pledgors and the Secured Party waive any right to require the marshaling of any
of the Collateral.

     20. Escrow Fees. The Escrow Agent shall be entitled to compensation (the
"Escrow Fees") in the amount equivalent to 0.3% of the value of the Escrowed
Shares (equaling $70.00 per share) on the date of Closing as defined in Stock
Purchase Agreement for the services to be rendered by it hereunder and in
addition the Escrow Agent shall be reimbursed for all losses, liabilities or
expenses, including reasonable attorneys' fees ("Reimbursement"), incurred or
made by it arising out of or in connection with its entering into this Agreement
or carrying out its duties hereunder, including the costs and expenses of
defending itself against any claim of liability in the premises. The Escrow Fees
shall be equally borne by the Pledgors and the Secured Party. The Reimbursement
shall be borne by the Pledgors when it is incurred and may be applied against
the Escrowed Shares or other securities, instruments or considerations in
replacement of or substitution of the Escrowed Shares as the case may be. For
avoidance of doubt, the Escrow Agent Fees only cover the services of taking
custody of the Escrowed Shares.

        21.    Miscellaneous.

(a) The Secured Party and the Pledgors hereby agree to jointly and severally
indemnify and hold the Escrow Agent harmless from and against any losses, costs,
claims, or actions arising from or incurred in connection with the escrow
agent's performance of its obligations hereunder unless such losses, costs,
claims or actions are incurred as a result of the Escrow Agent's willful
misconduct or gross negligence.

(b) The Escrow Agent may rely and shall be protected in acting or refraining
from acting upon any written notice, instruction or request furnished to it
hereunder and believed by it to


                                       11
<PAGE>   12
be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent may conclusively presume that the undersigned representative of
any party hereto which is a legal entity other than a natural person has full
power and authority to instruct the Escrow Agent on behalf of that party unless
written notice to the contrary is delivered to the Escrow Agent.

(c) The Escrow Agent shall not be liable for any action taken by it in good
faith and believed by it to be authorized or within the rights or powers
conferred upon it by this Agreement, and may consult with counsel of its own
choice and shall have full and complete authorization and protection for any
action taken or suffered by it hereunder in good faith and in accordance with
the opinion of such counsel.

(d) The Escrow Agent may resign and be discharged from its duties or obligations
hereunder by giving notice in writing of such resignation specifying a date upon
which such resignation shall take effect, whereupon a successor Escrow Agent
shall be appointed by the Secured Party. In the event that Escrow Agent resigns,
there shall not be any additional Escrow Fees to be paid by the Pledgors to the
successor escrow agent.

        IN WITNESS WHEREOF, the Pledgors and the Secured Party have caused this
Agreement to be duly executed and delivered by their officers thereunto duly
authorized as of the date first written above.
