         thirty (30) days advance written notice; provided, however, in such
         event the Company shall pay to Executive severance equal to three (3)
         months of his then existing salary as well as continuation of
         Executive's health and dental benefits and car allowance for such
         period. Severance payments shall be made on a bi-weekly basis. The
         severance period shall commence upon the conclusion of the notice
         period, or the first day following Executive's final day of employment.

                  (b) By the Company at any time immediately for cause by
         providing written notice to Executive. For purposes of this
         Agreement, "cause" shall include, without limitation, (i) a breach
         of any provision of this Agreement or a violation of any other duty
         or obligation to the Company; (ii) a failure to follow a written
         directive of the Board; (iii) fraud, misappropriation, dishonesty or
         embezzlement, or (iv) any willful or negligent misconduct, criminal
         conviction or similar conduct or activities.

                  (c) Immediately without notice upon the Executive's death or
         disability. For purposes of this Agreement, "disability" shall mean the
         inability of the Executive to perform his duties under this Agreement
         for a consecutive period of three (3) months or a non-consecutive
         period of six (6) months within any twelve-month period. In the event
         of the death or disability of the Executive, the Executive or the
         estate, beneficiary or legal representative of the Executive shall be
         entitled to any applicable death or disability benefits (other than
         key-man life insurance) which may be available under any benefit plans
         maintained by the Company solely for the benefit of the Executive at
         the time of the death or disability of the Executive.

Except as otherwise provided in subsection (a) above, upon the termination of
this Agreement and the employment of Executive hereunder, the Company shall have
no further obligation or liability whatsoever to Employee under this Agreement
except with respect to any stock options granted under the Plan which have
vested as of such date or salary earned by the Executive and not paid by the
Company prior to the date of termination.

                                       3

         8. ASSIGNMENT. By reason of the special and unique nature of the
services hereunder, it is agreed that neither party hereto may assign any
interest, rights or duties which it or he may have in this Agreement without the
prior written consent of the other party, except that upon any merger,
liquidation, or sale of all or substantially all of the assets of the Company to
another corporation, this Agreement shall inure to the benefit of and be binding
upon the Executive and the purchasing, surviving, or resulting company or
corporation in the same manner and to the same extent as though such company or
corporation were the Company.

         9. CONFIDENTIALITY.

         (a) Recognizing that the knowledge and information about, or
  relationships with, the business associates, partners, customers, clients,
  suppliers, personnel and agents of the Company and its affiliated companies
  and the business, financing and marketing methods, systems, plans, policies,
  techniques and know-how of the Company and of its affiliated companies
  (collectively, "Confidential Information") which the Executive has heretofore
  and shall hereafter receive, obtain or establish as an employee of the
  Company, or otherwise, is valuable and a unique asset of the Company, the
  Executive agrees that, during the Term of Employment and for a period of five
  (5) years thereafter, he shall hold all Confidential Information in the
  strictest confidence, and shall not (otherwise than pursuant to his duties
  hereunder), directly or indirectly, disclose without the express written
  consent of the Company, any Confidential Information pertaining to any person,
  firm, corporation or other entity, for any reason or purpose whatsoever. The
  Executive acknowledges and agrees that Confidential Information shall be
  deemed to include, without limitation, all knowledge, data or information
  stored on any electronic or other media. The Executive acknowledges and agrees
  that all memoranda, notes, records and other documents made or compiled by the
  Executive or made available to the Executive concerning any Confidential
  Information shall be the Company's exclusive property and shall be delivered
  by the Executive to the Company upon expiration or termination of this
  Agreement or at any other time upon the request of the Company.

         (b) The Executive hereby acknowledges that the services to be rendered
  by him are of a special, unique and extraordinary character and, in connection
  with such services, he will have access to Confidential Information. By reason
  of this, the Executive consents and agrees that if he violates any of the
  provisions of this Agreement with respect to confidentiality, the Company
  would sustain irreparable harm and, therefore, in addition to any other
  remedies which the Company may have under this Agreement or otherwise, the
  Company will be entitled to an injunction to be issued by any court of
  competent jurisdiction restraining the Executive from committing or continuing
  any such violation of this Agreement.

         (c) The provisions of this Section 9 shall survive the expiration or
  termination (for any reason) of this Agreement or any part thereof, without
  regard to the reason therefor.

terms of this Agreement is necessary to protect the Company's legitimate
business interests. The Executive agrees, that, during the Term of Employment
and for a period of three (3) years thereafter, he will not, on behalf of
himself, or on behalf of any person, company, corporation, partnership or

                                       4

other entity or enterprise, directly or indirectly, as an employee,
proprietor, owner, stockholder, partner, member, officer, director, manager,
lender, advisor, consultant or otherwise engage in any business or activity
competitive with the business activities of the Company or any subsidiary of
the Company as it is now or hereafter undertaken by the Company or any
subsidiary. The Executive further agrees that he will not, directly or
indirectly, during the Term of Employment and for a period of two years
thereafter, solicit the trade or patronage of any customers or prospective
customers of the Company, any subsidiary of the Company or of anyone who has
heretofore traded or dealt with the Company or any subsidiary of the Company
with respect to any technologies, services, products, trade secrets or other
matters in which the Company is active.

         (b) The Executive hereby acknowledges that the services to be rendered
by him under this Agreement are of a special, unique and extraordinary character
and, in connection with such services, he will have access to Confidential
Information. By reason thereof, the Executive consents and agrees that if he
violates any of the provisions of this Agreement with respect to noncompetition
or nonsolicitation, the Company would sustain irreparable harm and, therefore,
in addition to any other remedies which the Company may have under this
Agreement or otherwise, the Company shall be entitled to an injunction to be
issued by any court of competent jurisdiction restraining the Executive from
committing or continuing any such violation of this Agreement.

         (c) The provisions of this Section 10 shall survive the expiration or

         14. SEVERABILITY. If any provision hereof is unenforceable, illegal or
invalid for any reason whatsoever, such fact shall not affect the remaining

Company's rights hereunder arising out of the breach of any such restrictive
provisions, including, without limitation, the Company's rights to terminate
this Agreement.

         15. WAIVER. No failure or delay on the part of the Company or the
Executive in exercising any right, power or remedy hereunder shall operate as a

or remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy hereunder. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

         16. MODIFICATION. No amendment, modification, termination or waiver of
any provision of this Agreement nor consent to any departure by the Executive or
the Company therefrom shall in any event be effective unless the same shall be

Executive, as the case may be. Any such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given.

         17. TAXES. The Compensation payable is stated in gross amounts and
shall be subject to such withholding taxes and other taxes as may be required by
law.

         IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed by its duly authorized officer, and the Executive has hereunto set his
signature as of the day and year first above written.

"PLEDGED COLLATERAL"):

                  (a)      all shares of the capital stock of Pledgee owned by
Pledgor pursuant to Pledgor's exercise or rights under any stock option plan or
otherwise (the "PLEDGED SHARES"), and all dividends, cash, instruments and other
property or proceeds from time to time received, receivable or otherwise
distributed in respect of or in exchange for any or all of the Pledged Shares;
and

                  (b)      all voting trust certificates held by Pledgor
evidencing the right to vote any Pledged Shares subject to any voting trust.

         Immediately following acquisition of the Pledged Shares, Pledgor agrees
to deliver to Pledgee the stock certificates representing said Pledged Shares
along with an executed but otherwise uncompleted Assignment Separate From
Certificate in the form attached hereto as Exhibit A.

         The term "indebtedness" is used herein in its most comprehensive sense
and includes any and all advances, debts, obligations and liabilities
heretofore, now or hereafter made, incurred or created, whether voluntary, or
involuntary, and whether due or not due, absolute or contingent,

                                       1.
<PAGE>

liquidated or unliquidated, determined or undetermined, and whether recovery
upon such indebtedness may be or hereafter becomes unenforceable.

         2.       Pledgor hereby represents and warrants to Pledgee that as of
the date that the stock certificates representing the Pledged Shares are
delivered by Pledgor to Pledgee:

                  (a)      Pledgor shall be the sole holder of record and the
sole beneficial owner of the Pledged Collateral, free and clear of any lien
thereon or affecting title thereto, except for the lien created by this Pledge
Agreement.

                  (b)      None of the Pledged Shares will have been transferred
in violation of securities registration, securities disclosure or similar laws
of any jurisdiction to which such transfer may be subject with respect to which
such transfer could have a material adverse effect.

                  (c)      No consent, approval, authorization or other order of
any person and no consent or authorization of any governmental authority or
regulatory body is required to be made or obtained by Pledgor either (i) for the
pledge by Pledgor of the Pledged Collateral pursuant to this Pledge Agreement or
for the execution, delivery, or performance of this Pledge Agreement by Pledgor;
or (ii) for the exercise by Pledgee of the voting or other rights provided for
in this Pledge Agreement or the remedies in respect of the Pledged Collateral
pursuant to this Pledge Agreement, except as may be required in connection with
such disposition by laws affecting the offering and sale of securities
generally.

                  (d)      The pledge, grant of a security interest in, and
delivery of the Pledged Collateral pursuant to this Pledge Agreement, will have
created a valid first priority lien on and in the collateral pledged by Pledgor,
and the proceeds thereof, securing the payment of the Liabilities.

                  (e)      This Pledge Agreement will have been duly executed
and delivered by Pledgor and will constitute a legal, valid, and binding
obligation of Pledgor enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, or other similar laws
affecting the rights of creditors generally or by the application of general
equity principles.

         Pledgor covenants, warrants, and represents to Pledgee that all
representations and warranties contained in this Pledge Agreement shall be true
at the time the stock certificates representing the Pledged Shares are delivered
by Pledgor to Pledgee and shall continue to be true until the Liabilities have
been paid or otherwise satisfied in full.

         3.       At time, without notice, and at the expense of Pledgor,
Pledgee in its name or in the name of its nominee or of Pledgor may, but shall
not be obligated to: (1) collect by legal proceedings or otherwise all dividends
(except cash dividends other than liquidating dividends), interest, principal
payments and other sums now or hereafter payable upon or on account of said
Pledged Collateral; (2) enter into any extension, reorganization, deposit,
merger or consolidation agreement, or any agreement in any way relating to or
affecting the Pledged Collateral, and in connection therewith may deposit or
surrender control of such Pledged Collateral thereunder, accept other property
in exchange for such Pledged

                                       2.
<PAGE>

Collateral and do and perform such acts and things as it may deem proper, and
any money or property received in exchange for such Pledged Collateral shall be
applied to the indebtedness or thereafter held by it pursuant to the provisions
hereof; (3) insure, process and preserve the Pledged Collateral; (4) cause the
Pledged Collateral to be transferred to its name or to the name of its nominee;
and (5) exercise as to such Pledged Collateral all the rights, powers and
remedies of an owner, except that so long as no Event of Default (as defined in
the Note), exists under the Note and no default exists hereunder Pledgor shall
retain all voting rights as to the Pledged Shares.

         4.       Pledgor agrees to pay prior to delinquency all taxes, charges,
liens and assessments against the Pledged Collateral, and upon the failure of
Pledgor to do so, Pledgee at its option may pay any of them and shall be the
sole judge of the legality or validity thereof and the amount necessary to
discharge the same.

         5.       Pledgor agrees that Pledgor:

                  (a)      will not (1) sell, transfer or otherwise dispose of,
or grant any option or warrant with respect to, any of the Pledged Collateral
(or any part thereof or interest therein) except with the prior written consent
of Pledgee, or (2) create or permit to exist any lien or encumbrance upon or
with respect to any of the Pledged Collateral. If any Pledged Collateral, or any
part thereof, is sold, transferred or otherwise disposed of in violation of this
Section 5, the security interest of Pledgee shall continue in the Pledged
Collateral notwithstanding such sale, transfer or other disposition, and the
Pledgor will deliver any proceeds thereof to the Pledgee to be held as Pledged
Collateral hereunder.

                  (b)      shall, at Pledgor's own expense, promptly execute,
acknowledge, and deliver all such instruments and take all such actions as
Pledgee from time to time may reasonably request in order to ensure to Pledgee
the benefits of the lien in and to the Pledged Collateral intended to be created
by this Pledge Agreement.

                  (c)      shall maintain, preserve and defend the title to the
Pledged Collateral and the lien of Pledgee thereon against the claim of any
other person.

         6.       At the option of Pledgee and without necessity of demand or
notice, all or any part of the indebtedness of Pledgor shall immediately become
due and payable irrespective of any agreed maturity, upon the happening of any
of the following events: (1) failure to keep or perform any of the terms or
provisions of this Pledge Agreement; (2) the occurrence of an Event of Default
under the Note; or (3) the levy of any attachment, execution or other process
against the Pledged Collateral.

         7.       All advances, charges, costs and expenses, including
reasonable attorneys' fees, incurred or paid by Pledgee in exercising any right,
power or remedy conferred by this agreement, or in the enforcement thereof,
shall become a part of the indebtedness secured hereunder and shall be paid to
Pledgee by the undersigned immediately and without demand.

         8.       In the event of the nonpayment of any indebtedness when due,
whether by acceleration or otherwise, or upon the happening of any of the events
specified in paragraph 6, Pledgee may then, or at any time thereafter, at its
election, apply, set off, collect or sell in one or more sales, or take such
steps as may be necessary to liquidate and reduce to cash in the hands of
Pledgee in whole or in part, with or without any previous demands or demand of
performance or

                                       3.
<PAGE>

notice or advertisement, the whole or any part of the Pledged Collateral in such
order as Pledgee may elect, and any such sale may be made either at public or
private sale at its place of business or elsewhere, or at any broker's board or
securities exchange, either for cash or upon credit or for future delivery;
provided, however, that if such disposition is at private sale, then the
purchase price of the Pledged Collateral shall be equal to the public market
price then in effect, or, if at the time of sale no public market for the
Pledged Collateral exists, then, in recognition of the fact that the sale of the
Pledged Collateral would have to be registered under the Securities Act of 1933
and that the expenses of such registration are commercially unreasonable for the
type and amount of collateral pledged hereunder, Pledgee and Pledgor hereby
agree that such private sale shall be at a purchase price mutually agreed to by
Pledgee and Pledgor or, if the parties cannot agree upon a purchase price, then
at a purchase price established by a majority of three independent appraisers
knowledgeable of the value of such collateral, one named by Pledgor within 10
days after written request by the Pledgee to do so, one named by Pledgee within
such 10 day period, and the third named by the two appraisers so selected, with
the appraisal to be rendered by such body within 30 days after the appointment
of the third appraiser. The cost of such appraisal, including all appraisers'
fees, shall be charged against the proceeds of sale as an expense of such sale.
Pledgee may be the purchaser of any or all Pledged Collateral so sold and hold
the same thereafter in its own right free from any claim of Pledgor or right of
redemption. Demands of performance, notices of sale, advertisements and presence
of property at sale are hereby waived, and Pledgee is hereby authorized to sell
hereunder any evidence of debt pledged to it. Any sale hereunder may be
conducted by any officer or agent of Pledgee.

         9.       The proceeds of the sale of any of the Pledged Collateral and
all sums received or collected by Pledgee from or on account of such Pledged
Collateral shall be applied by Pledgee to the payment of expenses incurred or
paid by Pledgee in connection with any sale, transfer or delivery of the Pledged
Collateral, to the payment of any other costs, charges, attorneys' fees or
expenses mentioned herein, and to the payment of the indebtedness or any part
hereof, all in such order and manner as Pledgee in its discretion may determine.
Pledgee shall then pay any balance to Pledgor.

         10.      Upon the transfer of all or any part of the indebtedness
Pledgee may transfer all or any part of the Pledged Collateral and shall be
fully discharged thereafter from all liability and responsibility with respect
to such Pledged Collateral so transferred, and the transferee shall be vested
with all the rights and powers of Pledgee hereunder with respect to such Pledged
Collateral so transferred; but with respect to any Pledged Collateral not so
transferred Pledgee shall retain all rights and powers hereby given.

         11.      Until all indebtedness shall have been paid in full the power
of sale and all other rights, powers and remedies granted to Pledgee hereunder
shall continue to exist and may be exercised by Pledgee at any time and from
time to time irrespective of the fact that the indebtedness or any part thereof
may have become barred by any statute of limitations, or that the personal
liability of Pledgor may have ceased.

         12.      Pledgee may at any time deliver the Pledged Collateral or any
part thereof to Pledgor and the receipt thereof by Pledgor shall be a complete
and full acquittance for the Pledged Collateral so delivered, and Pledgee shall
thereafter be discharged from any liability or responsibility therefor.

                                       4.
<PAGE>

         13.      The rights, powers and remedies given to Pledgee by this
Pledge Agreement shall be in addition to all rights, powers and remedies given
to Pledgee by virtue of any statute or rule of law. Any forbearance, failure or
delay by Pledgee in exercising any right, power or remedy hereunder shall not be
deemed to be a waiver of such right, power or remedy, and any single or partial
exercise of any right, power or remedy hereunder shall not preclude the further
exercise thereof, and every right, power and remedy of Pledgee shall continue in
full force and effect until such right, power or remedy is specifically waived
by an instrument in writing executed by Pledgee.

         14.      If any provision of this Pledge Agreement is held to be
unenforceable for any reason, it shall be adjusted, if possible, rather than
voided in order to achieve the intent of the parties to the extent possible. In
any event, all other provisions of this Pledge Agreement shall be deemed valid
and enforceable to the full extent possible.

         15.      This Pledge Agreement shall be governed by, and construed in
accordance with, the laws of the State of California as applied to contracts
made and performed entirely within the State of California by residents of such
state.
