                                    AGREEMENT

1. The term "credit" or "indebtedness" is used throughout this Agreement in its
broadest and most comprehensive sense. Credit may be granted at the request of
any one Debtor without further authorization by or notice to any other Debtor.
Collateral shall be security for all nonconsumer indebtedness of Debtor to Bank
in accordance with the terms and conditions herein.

2. Debtor will: (a) pay when due all indebtedness to Bank; (b) execute such
Financing Statement(s) and other documents and do such other acts and things as
Bank may from time to time require to establish and maintain a valid perfected
security interest in Collateral, including payment of all costs and fees in
connection with any of the foregoing when deemed necessary by Bank; (c) furnish
Bank such information concerning Debtor and Collateral as Bank may from time to
time request, including but not limited to current financial statements; (d)
keep Collateral separate and identifiable and at the locations described herein
and permit Bank and its representatives to inspect Collateral and/or records
pertaining thereto from time to time during normal business hours; (e) not sell,
assign or create or permit to exist any lien on or security interest in
Collateral in favor of anyone other than Bank unless Bank consents thereto in
writing and at Debtor's expense upon Bank's request remove any unauthorized lien
or security interest and defend any claim affecting the Collateral; (f) pay all
charges against Collateral prior to delinquency including but not limited to
taxes, assessments, encumbrances, insurance and diverse claims, and upon
Debtor's failure to do so Bank may pay any such charge as it deems necessary and
add the amount paid to the indebtedness of Debtor hereunder; (g) protect, defend
and maintain the Collateral and the perfected security interest of Bank and
initiate, commence and maintain any action or proceeding to protect the

<PAGE>

Collateral; (h) reimburse Bank for any expenses, including but not limited to
reasonable attorneys' fees and expenses (including the allocated costs of Bank's
in-house counsel and legal staff) incurred by Bank in seeking to protect,
collect or enforce any rights in Collateral; (i) when required, provide
insurance in form and amounts and with companies acceptable to Bank and when
required, assign the policies or the rights thereunder to Bank; (j) maintain
Collateral in good condition and not use Collateral for any unlawful purpose;
(k) perform all of the obligations of the Debtor under the Collateral and save
Bank harmless from the consequence of any failure to do so; and (l) at its own
expense, upon request of Bank, notify any parties obligated to Debtor on any
Collateral to make payment to Bank and Debtor hereby irrevocably grants Bank
power of attorney to make said notifications and collections. Debtor hereby
appoints Bank the true and lawful attorney of Debtor and authorizes Bank to
perform any and all acts which Bank in good faith deems necessary for the
protection and preservation of Collateral or its value or Bank's perfected
security interest therein, including transferring any Collateral into its own
name and receiving the income thereon as additional security hereunder. Bank
does not assume any of the obligations arising under the Collateral.

3. Debtor warrants that: (a) it is and will be the lawful owner of all
Collateral free of all claims, liens, encumbrances and setoffs whatsoever, other
than the security interest granted pursuant hereto; (b) it has the capacity to
grant a security interest in Collateral to Bank; (c) all information furnished
by Debtor to Bank heretofore or hereafter, whether oral or written, is and will
be correct and true as of the date given; and (d) if Debtor is an entity, the
execution, delivery and performance hereof are within its powers and have been
duly authorized.

4. The term default shall mean the occurrence of any of the following events:
(a) failure of Debtor to make any payment of any indebtedness to Bank when due;
(b) deterioration or impairment of the value of any of the Collateral; (c) any
breach, misrepresentation or other default by Debtor under this Agreement or any
other agreements between Bank and Debtor; (d) a change in ownership or control
of ten percent or more of the equity interest of Debtor; or (e) the
deterioration of financial condition of Debtor which results in Bank deeming
itself, in good faith, insecure.

5. Whenever a default exists, Bank, at its option, may: (a) without notice
accelerate the maturity of any part or all of the indebtedness and terminate any
agreement for the granting of further credit to Debtor; (b) sell, lease or
otherwise dispose of Collateral at public or private sale; unless Collateral is
perishable and threatens to decline speedily in value or is of a type
customarily sold on a recognized market, Bank will give Debtor at least five (5)
days prior written notice of the time and place of any public sale or of the
time after which any private sale or any other intended disposition may be made;
(c) transfer any Collateral into its own name or that of its nominee; (d) retain
Collateral in satisfaction of obligations secured hereby, with notice of such
retention sent to Debtor as required by law; (e) notify any parties obligated on
any Collateral consisting of accounts, instruments, chattel paper, choses in
action or the like to make payment to Bank and enforce collection of any
Collateral; (f) file any action or proceeding which Bank may deem necessary or
appropriate to protect and preserve the right, title and interest of the Bank in
the Collateral; (g) require Debtor to assemble and deliver any Collateral to
Bank at a reasonably convenient place designated by Bank; (h) apply all sums
received or collected from or on account of Collateral, including the proceeds
of any sale thereof, to the payment of the costs and expenses incurred in
preserving and enforcing rights of Bank, including reasonable attorneys' fees
(including the allocated costs of Bank's in-house counsel and legal staff), and
indebtedness secured hereby in such order and manner as Bank in its sole
discretion determines; Bank shall account to Debtor for any surplus remaining
thereafter, and shall pay such surplus to the party entitled thereto, including
any second secured party who has made a proper demand upon Bank and has
furnished proof to Bank as requested in the manner provided by law; in like
manner, Debtor agrees to pay to Bank without demand any deficiency after any
Collateral has been disposed of and proceeds applied as aforesaid; and (i)
exercise its banker's lien or right of setoff in the same manner as though the
credit were unsecured. Bank shall have all the rights and remedies of a secured
party under the Uniform Commercial Code of California and in any jurisdiction
where enforcement is sought, whether in said state or elsewhere. All rights,
powers and remedies of Bank hereunder shall be cumulative and not alternative.
No delay on the part of Bank in the exercise of any

<PAGE>

right or remedy shall constitute a waiver thereof and no exercise by Bank of any
right or remedy shall preclude the exercise of any other right or remedy or
further exercise of the same remedy.

6. Debtor waives: (a) all right to require Bank to proceed against any other
person including any other Debtor hereunder or to apply any Collateral Bank may
hold at any time or to pursue any other remedy; Collateral, endorsers or
guarantors may be released, substituted or added without affecting the liability
of Debtor hereunder; (b) the defense of the Statute of Limitations in any action
upon any obligations of Debtor secured hereby; (c) any right of subrogation and
any right to participate in Collateral until all obligations secured hereby have
been paid in full.

7. The right of Bank to have recourse against Collateral shall not be affected
in any way by the fact that the credit is secured by a mortgage, deed of trust
or other lien upon real property.

8. The security interest granted herein is irrevocable and shall remain in full
force and effect until there is payment in full of the indebtedness or the
security interest is released in writing by Bank.

9. Debtor shall be obligated to request the release, reassignment or return of
Collateral after the payment in full of all existing obligations. Bank shall be
under no duty or obligation to release, reassign or return any Collateral except
upon the express written request of Debtor and then only where all of Debtor's
obligations hereunder have been paid in full.

10. If more than one Debtor executes this Agreement, the obligations hereunder
are joint and several. All words used herein in the singular shall be deemed to
have been used in the plural when the context and construction so require. Any
married person who signs this Agreement expressly agrees that recourse may be
had against his/her separate property for all of his/her obligations to Bank.

11. This Agreement shall inure to the benefit of and bind Bank, its successors
and assigns and each of the undersigned, their respective heirs, executors,
administrators and successors in interest. Upon transfer by Bank of any part of
the obligations secured hereby, Bank shall be fully discharged from any
liability with respect to Collateral transferred therewith.

12. Whenever possible, each provision of this Agreement shall be interpreted in
such manner as to be effective and valid under applicable law, but, if any
provision of this Agreement shall be prohibited or invalid under applicable law,
such provisions shall be ineffective to the extent of such prohibition or
invalidity without invalidating the remainder of such or the remaining
provisions of this Agreement.

The grant of a security interest in proceeds does not imply the right of Debtor
to sell or dispose of any Collateral without the express consent in writing by
Bank.
