the Company and Executive hereby agree to terminate their employment
relationship on the following basis:

     1. Resignation. Executive hereby resigns any and all positions with the
Company, including, without limitation, as Vice President, Finance and Strategic
Planning and Assistant Corporate Secretary and an employee of the Company as of
the Effective Date. Executive understands and agrees that he is giving up any
right or claim to future employment with the Company and any compensation or

pursuant to the terms of this Agreement:

          (a) In lieu of severance, concurrently with the execution of this
Agreement, Executive shall receive a bonus for the 2003 calendar year in the
amount of $20,500 less withholdings in accordance with applicable law. Also
concurrently with the execution of this Agreement, Executive shall receive a
lump-sum cash payment for accrued and unpaid vacation as well as accrued and

<PAGE>

August 19, 2002 (the "M&C Consulting Agreement") shall remain in full force and
effect until its expiration on July 31, 2004. Executive and Company agree to,
and Executive agrees to cause M&C to, continue to honor the terms of the M&C
Consulting Agreement through July 31, 2004; provided that the Company shall only
request that M&C provide reasonable and customary services under the M&C
Consulting Agreement; and, provided, further, that if Executive believes any
such requested services are unreasonable, Executive shall be entitled to contact
any member of the Company's board of directors to verify the validity of the
request. The Company shall remain obligated to pay M&C on the first business day
of each month, for the applicable month, the fees due under such M&C Consulting
Agreement through July 31, 2004. In addition to the foregoing, Executive agrees
to use his best efforts to assist with the completion and filing of the
Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2003
(the "10-Q"); however, no additional compensation shall be paid for Executive's
services in connection with the 10-Q.

          (c) The Company hereby covenants and agrees to submit the 90,000 share
conditional stock option grant made to Executive on September 12, 2003 (the
"Grant") to the Company's stockholders for approval at the Company's 2004 Annual
Meeting of Stockholders ("Annual Meeting") with a recommendation that the
stockholders approve such Grant. If the stockholders fail to approve the Grant
at the Annual Meeting, the Company shall pay Executive $504,900, less applicable
statutory withholdings and deductions, within seven (7) days after the Annual
Meeting.

          (d) Following the Effective Date, the Company shall continue to
provide Executive with medical, dental and vision benefits under the Company's

one hundred-percent (100%) of the COBRA premium with respect to medical, dental
and vision benefits for Executive and his spouse and dependents until December
31, 2003, provided that Executive elects to continue benefits under COBRA and
remains eligible for COBRA throughout that period.

          (e) All stock options previously granted to Executive shall become
fully vested as of the Effective Date, subject only to any applicable
stockholder approval requirements, and Executive shall be entitled to exercise
such options in whole or in part from time to time during the one year period
commencing on November 17, 2003.

     3.   Options. Executive and the Company are parties to certain written
agreements pursuant to which Executive has been granted options to purchase
stock in the Company. Executive acknowledges that although such options might be
identified as incentive stock options, such options may not be qualified for
treatment as incentive stock options, either now or in the future. Executive is
advised to consult with his personal tax advisor to determine whether the
options are qualified for treatment as incentive stock options. Except as set
forth in Section 2(c), 2(e) and this Section 3, Executive's rights under his
existing option agreements are not intended to be modified by this Agreement in
any way.

Effective Date.

          NOW THEREFORE, in consideration of the representations and agreements
contained herein, and of other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, and intending to be bound hereby,

compensate Consultant for these consulting services at the rate of $250 per
hour. It is the express intent of the parties that Consultant shall provide
consulting services to the Company as an independent contractor pursuant to this
Agreement. Consultant will not be an employee of the Company, and Consultant

Agreement, except as otherwise provided by this Agreement. Payments for
consulting services provided pursuant to this Section 5 shall be made to MFC.

complaints, causes of action, rights, demands, debts, damages, or accountings of
whatever nature, known or unknown which Consultant or MFC may have against the
Company Releasees, or any of them, based on any actions or events which occurred

               AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

          (c) No Assignment of Claims. Consultant and MFC represent and warrants
to the Company Releasees that there has been no assignment or other transfer of
any interest in any Claim which Consultant or MFC may have against the Company
Releasees, or any of them, and Consultant and MFC agree to indemnify and hold
the Company Releasees harmless from any liability, claims, demands, damages,
costs, expenses and attorneys' fees incurred as a result of any person asserting
any such assignment or transfer of any rights or Claims if Consultant or MFC
have made such assignment or transfer from such party.

          (d) No Suits or Actions. Consultant and MFC represent and warrant to
the Company that there have been no claims, suits, actions, complaints, or
charges filed by either of them against the Company Releasees, or any of them.

          (e) No Admission. Consultant and MFC further understand and agree that
neither the payment of money nor the execution of this Release shall constitute
or be construed as an admission of any liability whatsoever by the Company
Releasees.

     10.  General Release by the Company.

          (a) Release of Claims. The Company does hereby for itself and its
respective successors and assigns, release, acquit and forever discharge
