                                 R E C I T A L

        The Company desires to employ Executive in the capacity hereinafter

                               A G R E E M E N T

        NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth herein, the Company and the Executive,
intending to be legally bound, hereby agree as follows:

        1. EMPLOYMENT. The Company hereby agrees to employ the Executive as the
Senior Vice President of Sales and Marketing of the Company, reporting to the
President and Chief Executive Officer ("CEO") of the Company, and the Executive
accepts such employment and agrees to devote substantially all his business time
and efforts and skills on such reasonable duties as shall be assigned to him by
the Company commensurate with such position.

        2. TERM. The term of this Agreement will begin on January 15, 2001 (the
"Effective Date"), and shall continue thereafter for a one (1) year period and
shall be extended on each day for one (1) day so that the remaining term hereof
is always one (1) year unless either party elects to terminate this Agreement in
accordance with its provisions. Executive's employment is subject to earlier
termination as hereafter specified.

        3. POSITION AND DUTIES.

               3.1 SERVICE WITH THE COMPANY. During the term of this Agreement,
the Executive agrees to perform such reasonable duties and on such basis as
shall be assigned to him from time to time by the CEO; such duties, however, to
be commensurate with the Executive's position as Senior Vice President of Sales
and Marketing of the Company. In particular, and without limitation, such duties

and Marketing plans, guidance of day-to-day Sales and Marketing operations of
the Company, preparing operating budgets for presentation to the CEO, and

               3.2 NO CONFLICTING DUTIES. Except as provided in Exhibit A
hereto, during the term hereof, the Executive shall not serve as an officer,
director, employee, consultant or advisor to any other business; provided,
however, that the Executive may serve as a director of another corporation so
long as (i) such corporation does not compete, directly or indirectly, with the
Company or any of its Affiliates for such products as defined as "Competitive
Products" in Exhibit B attached to this Agreement, and (ii) such services do not
adversely affect Executive's ability to perform his duties under this Agreement,
unless such other service is approved by the CEO or the Board of Directors of
the Company. For purposes of this Agreement, the term "Affiliate" means any

   2
corporation, association or other business entity of which more than 50% of the
total voting power of shares of stock entitled to vote in the election of
directors, managers or trustees thereof is at the time owned or controlled by
the Company. Notwithstanding the foregoing, nothing contained herein shall
prevent Executive from making and expending any time of passive personal
investments and/or expending reasonable amounts of time for educational and
charitable activities. Except as provided in Exhibit A hereto, the Executive
confirms that he is under no contractual commitment inconsistent with his
obligations set forth in this Agreement.

        4. COMPENSATION.

               4.1 BASE SALARY. As compensation for all services to be rendered
by the Executive under this Agreement, the Company shall pay to the Executive a
base salary of $180,000 per year ("Base Salary"), which shall be paid on a
regular basis in accordance with the Company's normal payroll procedures and
policies. The amount of the Base Salary shall be reviewed by the Compensation
Committee of the Board of Directors, which may annually increase Executive's
Base Salary in amounts consistent with industry practices as determined in its
sole discretion. Executive's performance, the performance of the Company and
such other factors as the Compensation Committee of the Board of Directors deem
appropriate shall also be considered.

               4.2 INCENTIVE COMPENSATION PLANS. In addition to the Base Salary,
Executive shall be eligible to participate in management incentive compensation
plans approved by the Company's Board of Directors, such participation to be on
terms similar to those afforded to other management employees holding positions
with the Company. In addition to the Base Salary, the Executive shall be
entitled to a bonus of up to thirty percent (30%) of his Base Salary as
incentive compensation. All amounts to which the Executive may be entitled under
any incentive compensation plans shall be subject to the provisions, rules and
regulations of any such plan which apply to other management employees.

               4.3 PARTICIPATION IN BENEFIT PLANS. During the term of this
Agreement, Executive shall be entitled to participate in all employee benefit
plans, profit-sharing, stock options, vacation and other perquisite plans and
programs for which key employees of the Company are generally eligible. The
Executive's participation in any such plan or program shall be subject to the
provisions, rules and regulations thereof that are generally available to all
participants thereon, provided, however, in no event shall Executive's benefits
be less than the benefits described in Exhibit C.

               4.4 EXPENSES. In accordance with the Company's policies
established from time to time, the Company will pay or reimburse the Executive
for all reasonable and necessary out-of-pocket expenses incurred by him in the
performance of his duties under this Agreement, provided that Executive submits
appropriate vouchers and expense reports substantiating the amount thereof and
the business purposes for which such expenses were incurred.

        of Rule 13d-3 of the 1934 Act) of securities possessing more than fifty
        percent (50%) of the total combined voting power of the Company's
        outstanding securities pursuant to a tender or exchange offer made
        directly to the Company's stockholders which the Board does not
        recommend such stockholders to accept, or

                      (ii) A change in the composition of the Board over a
        period of thirty-six (36) consecutive months or less such that a

        elections for Board membership, to be comprised of individuals who
        either (A) have been Board members continuously since the beginning of
        such period or (B) have been elected or nominated for election as Board
        members during such period by at least a majority of the Board members
        described in clause (A) who were still in office at the time the Board
        approved such election or nomination.

stockholder-approved transactions to which the Company is a party:

                      (i) A merger or consolidation in which securities

        power of the Company's outstanding securities are transferred to a
        person or persons different from the persons holding those securities
        immediately prior to such transaction; or

        dissolution of the Company.

        5.     TERMINATION.

               5.1 TERMINATION BY THE COMPANY FOR CAUSE. Any of the following
acts or omissions shall constitute grounds for the Company to terminate the
Executive's employment pursuant to this Agreement for "cause":

                      (a) Willful misconduct by Executive causing
material harm to the Company but only if Executive shall not have discontinued
such misconduct within 30 days after receiving written notice from the Company
describing the misconduct and stating that the Company will consider the
continuation of such misconduct as cause for termination of this Agreement.

                      (b) Any material act or omission by the Executive
involving gross negligence in the performance of the Executive's duties to, or
material deviation from any of the policies or directives of, the Company, other
than a deviation taken in good faith by the Executive for


                                       3
   4
the benefit of the Company;

                      (c) Any illegal act by the Executive which materially and
adversely affects the business of the Company or any felony committed by
Executive, as evidenced by conviction thereof, provided that the Company may
suspend the Executive with pay while any allegation of such illegal or felonious
act is investigated.

                      Termination by the Company for cause shall be accomplished
by written notice to the Executive and shall be preceded by a written notice
providing a reasonable opportunity for the Executive to correct his conduct.

               5.2 TERMINATION FOR DEATH OR DISABILITY. In addition to
termination for cause pursuant to Section 5.1 hereof, the Executive's employment

means an inability of Executive, due to a physical or mental illness, injury or
impairment, to perform a substantial portion of his duties for a period of one
hundred eighty (180) or more consecutive days, as determined by a competent
physician selected by the Company's Board of Directors and reasonably agreed to
by the Executive, following such one hundred eighty (180) day period.

               5.3 TERMINATION FOR GOOD REASON. Executive's employment pursuant
to this Agreement may be terminated by the Executive for "good reason" if the
Executive voluntarily terminates his employment as a result of any of the
following:

                      (a) Without the Executive's prior written consent, a
reduction in his then current Base Salary;

                      (b) Without Executive's prior written consent, a
relocation of the Executive's place of employment outside of Orange County,
California;

                      (c) Resignation as a result of unlawful discrimination, as
evidenced by a final court order;

                      (d) A reduction in duties and responsibilities which
results in the Executive no longer having duties customary for a Senior Vice
President of Sales and Marketing; or

                      (e) The Company materially breaches any provision of this
Agreement.

               5.4 TERMINATION WITHOUT CAUSE. The Company may terminate this
Agreement, and the employment of the Executive under this Agreement, without
cause at any time upon at least thirty (30) days prior written notice to the
Executive.

               5.5 PAYMENTS UPON REMOVAL OR TERMINATION. If during the term of
this Agreement, the Executive resigns for one of the reasons stated in Section
5.3, or the Company terminates the Executive's service, except as provided in
Sections 5.1 or 5.2 hereof, the Executive shall be entitled to the following
compensation: (i) the portion of his then current Base Salary which has accrued
through his date of termination, (ii) any payments for unused vacation and
reimbursement expenses, which are due, accrued or payable at the date of
Executive's termination, (iii) severance payment in an amount (the "Severance
Amount") equal to Executive's then-current


                                       4
   5
Base Salary, payable for the remainder of the Term; and (iv) to the extent not
already vested under Section 4.5 or otherwise all of Executive's options to
purchase shares of the Company's common stock and restricted stock shall
accelerate and automatically vest by one additional year, and such options shall
otherwise be exercisable in accordance with their terms. In addition, in such
event, Executive shall be entitled to (a) a prorated payment equal to the target
bonus amount for which Executive would be eligible for the year in which such
resignation or termination occurred, and (b) continuation of the insurance
benefits set forth in Exhibit C and, to the extent permissible, participation in
the Company's 401k plan, for the remainder of the Term.

               All payments required to be made by the Company to the Executive
pursuant to this Section 5.5 shall be paid on a regular basis in accordance with
the Company's normal payroll procedures and policies, including, without
limitation, the Severance Amount which shall be paid at such times and in such
amounts consistent with the Company's normal payroll procedures and policies
over the number of months immediately succeeding the date of termination that is
equal to the number of months of Base Salary payable as the Severance Amount. If
the Company terminates the Executive's employment pursuant to Sections 5.1 or
5.2, or if the Executive voluntarily resigns (except as provided in Section
5.3), then the Executive shall be entitled to only the compensation set forth in
items (i) and (ii) of the first paragraph of this Section 5.5.

               To the extent that any or all of the payments and benefits
provided for in this Agreement constitute "parachute payments" within the
meaning of Section 280G of the Internal Revenue Code (the "Code") and, but for
this paragraph, would be subject to the excise tax imposed by Section 4999 of
the Code, then at the Executive's election:

                      (A) The Executive shall receive all such payments and
        benefits the Executive is entitled to receive hereunder, and any
        liability for taxes pursuant to the above shall be the liability solely
        of the Executive; or

                      (B) The aggregate amount of such payments and benefits
        shall be reduced such that the present value thereof (as determined
        under the Code and applicable regulations) is equal to 2.99 times the
        Executive's "base amount" (as defined in the Code).

               The determination of any reduction or increase of any payment or
benefits under this paragraph 5 pursuant to the foregoing provision shall be
made by a nationally recognized public accounting firm chosen by the Company in
good faith, and such determination shall be conclusive and binding on the
Company and the Executive.

        6. ASSIGNMENT. This Agreement shall not be assignable, in whole or in
part, by either party without the written consent of the other party, except

and obligations under this Agreement to an Affiliate or to any corporation, firm
or other business entity (i) with or into which the Company may merge or
consolidate, or (ii) to which the Company may sell or transfer all or
substantially all of its assets. After any such assignment by the Company, the
Company shall be discharged from all further liability hereunder and such
assignee shall thereafter be deemed to be the Company for the purposes of all
provisions of this Agreement including this Section 6.

        7. SUCCESSORS. This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,

                                       5
   6
