Executive Management Committee. Employee shall perform all reasonable duties
assigned by the Company consistent with those assigned to other employees of the
Company possessing a comparable position. Employee understands and agrees that
his employment with the Company may require travel and overnight stays ("Travel

Employment Term, the Employee shall devote all of his normal business time to
the performance of his duties to the Company and Employee shall diligently
perform his duties to further the interests of the Company.

         1.3. COMPENSATION AND BENEFITS.

                  1.3.1 BASE SALARY. In consideration of the services rendered
to the Company hereunder by the Employee and the Employee's covenants hereunder,
including but not limited to, his covenants under Sections 3 and 5 below, and
under the Company's Confidentiality, Proprietary Information and Inventions
Agreement, the Company shall, during the Employment Term, pay the Employee a
salary at the annual rate of One Hundred Fifty Thousand Dollars ($150,000) (the

forms of compensation paid to the Employee hereunder shall be subject to all
applicable taxes required to be withheld by the Company pursuant to federal,
state or local law. The Employee shall be solely responsible for income taxes
imposed on the Employee by reasons of any cash or non-cash compensation and
benefits provided by this Agreement.

                  1.3.2 TARGET BONUS. Employee will be entitled to an annual

Employee's achievement of goals established by the Company, of which One Hundred
Fifty Thousand Dollars ($150,000) shall be guaranteed during the first year of
the Agreement.

                  1.3.3 BENEFITS PACKAGE. Employee shall be entitled to receive
such employee benefits as may be in effect from time to time as are afforded to
other comparable employees of the Company. For purposes of determining
eligibility and entitlement to benefits, Employee's date of hire will be
considered to be his hire date by Target, to the extent permissible by law.

                        Employee shall be provided with reimbursement (on a
basis that is "grossed up" for taxes) for term life insurance coverage in the
amount of $1.5 million and long term disability coverage in the amount of
$500,000 per year, both commencing on the Hire Date.

                  1.3.4 STOCK OPTIONS. Subject to approval by the Company's
Board of Directors, the Company shall grant to Employee within sixty (60) days
after Closing, in accordance with the terms of the Company's Stock Option Plan,
an option to purchase a total of Two Hundred Twenty Thousand (220,000) shares of
the Company's common stock (the "Option") at a grant price equal to the fair
market value of the Company's common stock on the


                                       2
   3


date of grant. The Option shall vest in four (4) equal installments as follows:
twenty-five percent (25%) upon Employee's completion of one (1) year of
employment with the Company and the remaining seventy-five percent (75%) in
twelve (12) equal installments upon Employee's completion of each three (3)
month period of employment thereafter. The Option shall be subject to the
Company's Stock Option Plan and form stock option documents. In addition,
Employee's shares of Target common stock and/or options to purchase shares of
Target common stock will be converted to shares of Company common stock and/or
options to purchase shares of Company common stock pursuant to the terms of the
Merger Agreement.

                  1.3.5 VACATION. Employee shall be entitled to vacation each
fiscal year in accordance with the vacation policies of the Company in effect
for other comparable employees of the Company. For purposes of determining
eligibility and entitlement to vacation, Employee's date of hire will be
considered to be his hire date by Target.

                  1.3.6 EXPENSES. The Company shall, upon receipt from the
Employee of signed and itemized lists of expenditures with supporting receipts
to the extent required by applicable income tax regulations and the Company's
reimbursement policies, reimburse the Employee for all out-of-pocket business
expenses reasonably incurred by the Employee in connection with his employment
hereunder.

                  1.3.7 TRAVEL. The Company agrees to reimburse Employee for
first class travel in connection with Employee's Travel Assignments.

                  1.3.8 ACCELERATION OF TARGET OPTIONS. Employee agrees to waive
all rights (if any) to acceleration of unvested options to purchase Target stock
("Target Option") contained in any agreement, stock option agreement, or any
other document, including but not limited to his offer letter dated April 5,
1999 (the "Offer Letter"), that grants Employee Target Options prior to Closing,
including, but not limited to, those Target Options granted on or about June 6,
2000. In connection therewith, Employee expressly acknowledges, understands and
agrees that he will not receive any accelerated vesting of Target or Company
options granted to Employee prior to Closing, including, but not limited to,
those Target Options granted on or about June 6, 2000. Employee further agrees
that his offer letter from Target dated April 5, 1999 shall cease to be
effective on the Closing and shall from the date of this Agreement cease to
govern in any way the effect of the Transaction on Employee's options to acquire
Target stock. Accordingly, this Agreement shall be the sole source of any
provision for the acceleration of vesting of Target Options as a result of or
following the Transaction, and the following are conditions of such vesting:
Each of Employee's Target Options from all option grants made by Target to
Employee prior to Closing, including, but not limited to, those Target Options
granted on or about June 6, 2000, will continue to vest in accordance with the
original vesting schedule for so long as Employee is employed by the Company.
Upon termination of employment for any reason, fifty percent (50%) of each of
Employee's unvested Target Options as of the date of termination shall become
fully vested.

                  3.2. NO DIVERSION OF OTHERS. During the Employment Term and
for one (1) year from the date that Employee's employment with the Company is
terminated, for any reason, the Employee shall not, either for himself or for
any other person, firm, corporation or other entity, directly or indirectly, or
by action in concert with others:

                       (i) directly or indirectly,  individually  or on behalf
of any other person, firm, partnership, corporation, or business entity of any
type, solicit, assist or in any way encourage any current employee or consultant

employment relationship or consulting relationship with the Company or
subsidiary nor will Employee solicit the employment services of any former

been voluntarily terminated for less than six (6) months; or

                       (ii) divert or take away or attempt  to divert or take

representatives of the Company for the purpose of organizing any such
competitive business.

         4. INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

                  The Employee acknowledges and agrees that any breach of the
terms of Section 3 above would result in irreparable injury and damage to the
Company for which the Company would have no adequate remedy at law; the Employee
therefore also acknowledges and agrees that in the event of such breach or any
threat of breach, the Company shall be entitled to an immediate injunction and
restraining order to prevent such breach and/or threatened breach and/or
continued breach by the Employee and/or any and all persons and/or entities
acting for and/or with the Employee, without having to prove damages, in
addition to any other remedies to which the Company may be entitled at law or in
equity. The terms of this paragraph shall not prevent the Company from pursuing
any other available remedies for any breach or threatened breach hereof,
including but not limited to the recovery of damages from the Employee.

that would be violated by his execution or performance of this Agreement,
including, but not limited to, any non-competition agreement presently in
effect, and (ii) the Employee is not subject to any pending or, to the

Agreement and continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Employee in Section 3. The
existence of any claim or cause of action by the Employee against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of the covenants and agreements of
Section 3 above.
