lender accords its own property,  it being understood that Lender shall not have
any  responsibility for (i) ascertaining or taking action with respect to calls,
conversions,  exchanges,  maturities,  tenders or other matters  relative to any

parties with respect to any Pledged Collateral.

         SECTION 11. Remedies  upon Default.  If any Event of Default shall have
occurred and be continuing:

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
Uniform  Commercial  Code (the  "Code")  in  effect in the State of  California,
except as required by mandatory  provisions of law and except to the extent that
the validity or  perfection  of the  security  interest  hereunder,  or remedies
hereunder,  in respect of any particular  Pledged Collateral are governed by the
laws of a  jurisdiction  other than the State of  California,  at that time, and
Lender may also,  without notice except as specified below,  exercise any voting
or other  consensual  rights with  respect to the Pledged  Collateral,  sell the
Pledged  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 Lender's  offices or
elsewhere, for cash, on credit or for future delivery, and upon such other terms
as Lender may deem commercially  reasonable.  Pledgor agrees that, to the extent
notice of sale shall be required by law, at least ten days' notice to Pledgor of
the time and place of any public sale or the time after  which any private  sale
is to be made shall  constitute  reasonable  notification.  Lender  shall not be
obligated to make any sale of Pledged  Collateral  regardless  of notice of sale
having  been given.  Lender may adjourn any public or private  sale from time to
time by announcement  at the time and place fixed  therefor,  and such sale may,

adjourned.

         (b) Any cash held by Lender as Pledged Collateral and all cash proceeds

discretion of Lender,  be held by Lender as  collateral  for, and then or at any
time thereafter applied (after payment of any amounts payable to Lender pursuant
to  Section  13) in whole or in part by Lender  against,  all or any part of the
Obligations  in such order as Lender  shall  elect.  Any surplus of such cash or
cash proceeds and interest accrued thereon, if any, held by Lender and remaining
after payment in full of all the Obligations shall be paid over to Pledgor or to

                                       5

<PAGE>

whomsoever  may be lawfully  entitled to receive  such  surplus,  provided  that
Lender  shall have no  obligation  to invest or  otherwise  pay  interest on any
amounts held by it in connection with or pursuant to this Agreement.

         (c) All rights and remedies of Lender  expressed herein are in addition
to all other rights and remedies possessed by Lender in the Loan Agreement,  all
third party  guaranties  and any other  agreement or instrument  relating to the
Obligations.

         SECTION 12. Expenses. Pledgor will upon demand pay to Lender the amount

preservation of, or the sale of, collection from, or other realization upon, any
of the  Pledged  Collateral,  (iii) the  exercise or  enforcement  of any of the
rights of Lender  hereunder of (iv) the failure by Pledgor to perform or observe
any of the provisions hereof.

         SECTION 13.  Security Interest Absolute. All rights of Lender and secur
-ity interests  hereunder,  and all obligations of Pledgor  hereunder,  shall be

                  (i) any  lack of  validity or enforceability of the Promissory
Note, or any other agreement or instrument relating thereto;

                  (ii) any change in the time, manner, place or terms of payment
of,  or in any  other  term  of,  all or any of the  Obligations,  or any  other
amendment or waiver of or any consent to any departure from the Promissory Note;

                  (iii) any sale, exchange,  release, surrender or nonperfection
of any other collateral,  or any release or amendment or waiver of or consent to
departure  from any guaranty,  for all or any of the  Obligations  or any setoff
against all or any of the Obligations; or

                  (iv) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Borrower or a third-party Pledgor.

         SECTION 14. Amendments, etc. No amendment or waiver of any provision of
this Agreement,  nor consent to any departure by Pledgor herefrom,  shall in any

         (k) Pledgor (i) is not an "investment  company" as that term is defined
in the  Investment  Company Act of 1940,  as amended,  (ii) does not directly or
indirectly  control and is not  controlled by a company which is an  "investment
company" as that term is defined in such Act and (iii) is not otherwise  subject

         (l) The  representations  and  warranties set forth herein hereof shall
survive the  execution  of this  Agreement  and shall  continue as long as there
shall be any  Indebtedness  outstanding  under this Agreement as if repeated and
given again to Lender on each day during the term hereof.

         SECTION 6. Further Assurances.  Pledgor agree that at any time and from
time to time,  at the  expense of Pledgor,  Pledgor  will  promptly  execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable,  or that Lender may request,  in order to perfect
and protect any security  interest  granted or purported to be granted hereby or
to enable Lender to exercise and enforce its rights and remedies  hereunder with
respect to any Pledged  Collateral,  including without  limitation filing one or
more UCC-1s to protect Lender's  security  interest in Pledgor Rights and making
any filing  statement or appearance  before or with any insurance  commission or
other regulatory authority.  Pledgor authorizes Lender to file, in jurisdictions
where this authorization will be given effect, a financing statement signed only
by Lender  covering  the  Pledged  Collateral.  Pledgor  will join Lender at its
request in executing all financial statements in form satisfactory to Lender and
Pledgor will pay the cost of filing or recording any such financial statement or
of this Agreement if it is deemed by Lender to be necessary or desirable.

         SECTION 7. Transfers and Other Liens; Additional Shares.

         (a) Pledgor agree that it will not (i) sell or otherwise dispose of, or
grant any option with respect to, any of the Pledged collateral,  or (ii) create
or permit to exist any lien,  security  interest or other charge or  encumbrance
upon or with respect to any of the Pledged  Collateral,  except for the security
interest under this Agreement.

         (b)  Pledgor  agree  that it will (i) cause the  issuer of the  Pledged
Shares  not to  issue  any  stock  or  other  securities  in  addition  to or in
substitution for the pledged Shares issued by such issuer, except to Pledgor and
(ii) pledge hereunder, immediately upon its acquisition (directly or indirectly)
thereof,  any and all  additional  shares  of stock or other  securities  of the
issuer of the Pledged Shares.

         SECTION 8. Lender  Appointed  Attorney-in-Fact.  Pledgor hereby appoint
Lender as Pledgor's attorney-in-fact, with full authority in the place and stead
of  Pledgor  and in the  name of  Pledgor  or  otherwise,  from  time to time in
Lender's  discretion  to take any  action and to execute  any  instrument  which
Lender may deem  necessary  or  advisable  to  accomplish  the  purposes of this
Agreement,  including,  without limitation,  to receive, endorse and collect all
instrument  made  payable  to  Pledgor   representing   any  dividend  or  other

         SECTION 9. Lender May Perform. If Pledgor fail to perform any agreement
contained  herein,  Lender may itself  perform,  or cause  performance  of, such
agreement,  and the expenses of Lender incurred in connection therewith shall be
payable by Pledgor under Section 13.

         SECTION 10. Reasonable Care.  Lender shall exercise  reasonable care in
the custody of the Pledged  Collateral in its possession or control hereunder at
any  time.  Lender  shall be  deemed to have  exercised  reasonable  care in the
custody and  preservation  of the Pledged  collateral  in its  possession if the
Pledged  Collateral  is  accorded  treatment  substantially  equal to that which
lender accords its own property,  it being understood that Lender shall not have
any  responsibility for (i) ascertaining or taking action with respect to calls,
conversions,  exchanges,  maturities,  tenders or other matters  relative to any
Pledged Collateral,  whether or not Lender has or is deemed to have knowledge of
such matters,  or (ii) taking any necessary steps to preserve rights against any
parties with respect to any Pledged Collateral.

         SECTION 11. Remedies  upon Default.  If any Event of Default shall have
occurred and be continuing:

         (a)  Lender may  exercise  in respect  of the  Pledged  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
Uniform  Commercial  Code (the  "Code")  in  effect in the State of  California,
except as required by mandatory  provisions of law and except to the extent that
the validity or  perfection  of the  security  interest  hereunder,  or remedies
hereunder,  in respect of any particular  Pledged Collateral are governed by the
laws of a  jurisdiction  other than the State of  California,  at that time, and
Lender may also,  without notice except as specified below,  exercise any voting
or other  consensual  rights with  respect to the Pledged  Collateral,  sell the
Pledged  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 Lender's  offices or
elsewhere, for cash, on credit or for future delivery, and upon such other terms
as Lender may deem commercially  reasonable.  Pledgor agrees that, to the extent
notice of sale shall be required by law, at least ten days' notice to Pledgor of
the time and place of any public sale or the time after  which any private  sale
is to be made shall  constitute  reasonable  notification.  Lender  shall not be
obligated to make any sale of Pledged  Collateral  regardless  of notice of sale
having  been given.  Lender 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.

         (b) Any cash held by Lender as Pledged Collateral and all cash proceeds
received  by  Lender  in  respect  of any  sale  of,  collection  from or  other
realization  upon  all or  any  part  of  the  Pledged  Collateral  may,  in the
discretion of Lender,  be held by Lender as  collateral  for, and then or at any
time thereafter applied (after payment of any amounts payable to Lender pursuant
to  Section  13) in whole or in part by Lender  against,  all or any part of the
Obligations  in such order as Lender  shall  elect.  Any surplus of such cash or
cash proceeds and interest accrued thereon, if any, held by Lender and remaining
after payment in full of all the Obligations shall be paid over to Pledgor or to

                                       5

<PAGE>

whomsoever  may be lawfully  entitled to receive  such  surplus,  provided  that
Lender  shall have no  obligation  to invest or  otherwise  pay  interest on any
amounts held by it in connection with or pursuant to this Agreement.

         (c) All rights and remedies of Lender  expressed herein are in addition
to all other rights and remedies possessed by Lender in the Loan Agreement,  all
third party  guaranties  and any other  agreement or instrument  relating to the
Obligations.

         SECTION 12. Expenses. Pledgor will upon demand pay to Lender the amount
of any and all reasonable  expenses,  including the reasonable fees and expenses
of its  counsel  and of any  experts  and  agents,  which  Lender  may  incur in
connection with (i) the  administration  of this Agreement,  (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the  Pledged  Collateral,  (iii) the  exercise or  enforcement  of any of the
rights of Lender  hereunder of (iv) the failure by Pledgor to perform or observe
any of the provisions hereof.

         SECTION 13. Security Interest Absolute. All rights of Lender and secur-
ity interests  hereunder,  and all  obligations of Pledgor  hereunder,  shall be
absolute and unconditional irrespective of:

                  (i) any lack of validity or enforceability  of the  Promissory
Note, or any other agreement or instrument relating thereto;

                  (ii) any change in the time, manner, place or terms of payment
of,  or in any  other  term  of,  all or any of the  Obligations,  or any  other
amendment or waiver of or any consent to any departure from the Promissory Note;

                  (iii) any sale, exchange,  release, surrender or nonperfection
of any other collateral,  or any release or amendment or waiver of or consent to
departure  from any guaranty,  for all or any of the  Obligations  or any setoff
against all or any of the Obligations; or

                  (iv) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Borrower or a third-party Pledgor.

         SECTION 14. Amendments, etc. No amendment or waiver of any provision of
this Agreement,  nor consent to any departure by Pledgor herefrom,  shall in any
event be effective unless the same shall be in writing and signed by Lender, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

         SECTION 15. Addresses for Notices. All notices and other communications
provided   for   hereunder   shall   be  in   writing   (including   telegraphic
communication),  mailed or  telegraphed  or delivered to it,  addressed to it at
such party's address  specified in the Loan Agreement;  or as to either party at
such other address as shall be  designated by such party in a written  notice to
each other party  complying as to delivery with the terms of this  Section.  All
such  notices  and other  communications  shall,  when  mailed  or  telegraphed,
respectively,  be  effective  when  deposited  in the mails or  delivered to the
telegraph company, respectively, addressed as aforesaid.

         SECTION  16.  Continuing  Security  Interest;  Transfer  of Note.  This

and shall (i)  remain in full  force and  effect  until  payment  in full of the
Obligations,  (ii) be binding upon Pledgor, its successors and assigns and (iii)
inure to the  benefit of Lender and its  successors,  transferees  and  assigns.
Without limiting the generality of the foregoing clause (iii), Lender may assign
or otherwise  transfer  the Note to any other  person or entity,  and such other
person or entity shall thereupon  become vested with all the benefits in respect
thereof  granted to Lender herein or otherwise.  Upon the payment in full of the
Obligations,  Pledgor  shall be entitled to the return,  upon its request and at
its expense,  of such of the Pledged  Collateral  as shall not have been sold or
otherwise applied pursuant to the terms hereof.

         SECTION 17.  Governing Law; Terms.  This Agreement shall be governed by
and construed in accordance with the laws of the State of California,  except as
required  by  mandatory  provisions  of law and  except to the  extent  that the
validity  or  perfection  of  the  security  interest  hereunder,   or  remedies
hereunder,  in respect of any particular  Pledged Collateral are governed by the
laws of a  jurisdiction  other than the State of  California.  Unless  otherwise
defined herein or in the Note,  terms defined in the Uniform  Commercial Code in
the State of California are used herein as therein defined.

         IN WITNESS  WHEREOF,  Pledgor  has  caused  this  Agreement  to be duly
executed and delivered by its officer  thereunto duly  authorized as of the date
first above written.
