WHEREAS, the Company desires assurance of the association and services of EMPLOYEE in order to retain EMPLOYEE's experience, skills, abilities, background and knowledge, and is willing to engage EMPLOYEE's services on the terms and conditions set forth in this Agreement; and C. WHEREAS, EMPLOYEE desires to be in the employ of the Company, and is willing to accept such employment on the terms and conditions set forth in this Agreement. AGREEMENT: In consideration of the foregoing premises and the mutual covenants herein contained, and for other good and valuable consideration, the Parties, intending to be legally bound, agree as follows: 1 Employment. ---------- 1.1 The Company hereby employs EMPLOYEE, and EMPLOYEE hereby accepts employment by the Company, upon the terms and conditions set forth in this Agreement for the period beginning on the date hereof and ending as provided in Paragraph 3 hereof (the "Employment Period"). 1.2 During the Employment Period, EMPLOYEE shall serve as Division President and shall have the normal duties, responsibilities and authority of such office, unless otherwise determined from time to time by the Company's Chief Executive Officer or Board of Directors. EMPLOYEE shall do and perform all services, acts or things necessary or advisable to carry out the job duties assigned by the Company, provided, however, that at all times during his employment EMPLOYEE shall be subject to the direction and policies from time to time established by the Chief Executive Officer or the Board of Directors of the Company. 1.3 Within thirty (30) days of execution of this Agreement, EMPLOYEE shall submit an annual budget for his division, including a month-to-month breakdown, for review and approval by the Chief Executive Officer of the Company. Upon approval, the budget as amended in accordance with the provisions herein, shall determine the expenditures for and the spending authority of EMPLOYEE for his division for the periods stated. The budget may be revised from time to time as determined by the Chief Executive Officer. Any unbudgeted expense in excess of $500, and any budgeted expense in excess of $2,500, either individually or in the aggregate, in any thirty (30) day period for any single entity or purpose must be pre-approved by the Chief Executive Officer of the Company. 2 2 Loyal and Conscientious Performance; Noncompetition. --------------------------------------------------- 2.1 During his employment by the Company, EMPLOYEE shall devote his full energies, interest, abilities and productive time to the proper and efficient performance of this Agreement and shall not, without the prior written consent of the Chief Executive Officer or the Board of Directors of the Company, directly or indirectly, render services of a business, professional or commercial nature to any other person or entity, whether for compensation or otherwise, or engage in any business activities competitive with or adverse to the Company's business or welfare, whether alone, as a partner, or as a shareholder, officer or director of any other corporation, or as a trustee, fiduciary or in a similar representative capacity. 3 Term of Employment. ------------------ 3.1 Subject to earlier termination as provided in this Agreement, EMPLOYEE shall be employed pursuant to the terms of this Agreement for a three (3) year term beginning on February 15, 2000 and expiring at midnight on February 14, 2003. 4 Compensation. ------------ 4.1 Beginning with the Effective Date of this Agreement, Company shall pay EMPLOYEE a salary (the "Base Salary") of One Hundred Eighty Thousand Dollars ($180,000.00) per year, payable in accordance with the Company's normal payroll practices for employees. Such salary shall be prorated for any partial employment on the basis of a 30-day calendar month. 4.2 EMPLOYEE's compensation may be changed from time to time by mutual agreement of EMPLOYEE and the Board of Directors of the Company. Any such agreement shall be evidenced by a written amendment of this Agreement, which, among other things, shall 3 specify with particularity any change in EMPLOYEE's compensation and the date or dates when each such change shall become effective. 4.3 Immediately upon the execution of this Agreement by the parties, EMPLOYEE shall be awarded an additional equity compensation package regarding common voting shares of the Company according to the terms and conditions described in Exhibit A to this Agreement. 4.4 In addition to the Base Salary payable to EMPLOYEE hereunder, the EMPLOYEE shall be entitled to the following benefits during the Employment Period: 4.4.1 All benefits to which the senior management of the Company are entitled, as determined by the Company's Board of Directors, on terms comparable thereto, including but not limited to, participation in any and all pension and profit sharing plans, bonus and incentive payment programs, group life insurance policies and plans, medical and health policies and plans, and the like, which may be maintained by the Company for the benefit of its executives. 4.4.2 Three (3) weeks vacation per year, which shall accrue annually beginning with the effective date of this Agreement. If the EMPLOYEE does not utilize the entire three weeks of annual vacation in a given year, he may carry over such weeks into the following calendar year, provided that such accrual shall not exceed the maximum accrual permitted under current Company policy. 4.4.3 EMPLOYEE shall be based in Seattle, Washington until the Board of Directors and EMPLOYEE mutually agree that the relocation of EMPLOYEE to San Diego, California is necessary. At such time as EMPLOYEE does relocate to San Diego, the Company shall reimburse to EMPLOYEE for his moving expenses to San Diego in an amount up to Twenty Thousand Dollars ($20,000.00) of such moving expenses, provided EMPLOYEE provides to the Company appropriate documentation supporting such expenses. 4 4.5 The Company shall reimburse EMPLOYEE for all reasonable out-of-pocket expenses incurred by him in the course of performing his duties under this Agreement, which are consistent with the Company's policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company's requirements with respect to reporting and documentation of such expenses. 4.6 All of EMPLOYEE's compensation shall be subject to customary federal and state withholding taxes and any other employment taxes as are commonly required to be collected or withheld by the Company. 5 Termination. ----------- 5.1 The Company may terminate this Agreement for Cause (as defined herein) by delivery of written notice to EMPLOYEE specifying the cause or causes relied upon for such termination. If EMPLOYEE's employment under this Agreement is terminated by the Company for Cause before the last day of any calendar month, EMPLOYEE shall be entitled to receive as compensation for such calendar month, only the Base Salary set forth in Section 4.1 prorated to the date of termination on the basis of a 30-day calendar month and all accrued and unreimbursed business expenses incurred by Williams on or before such date. Grounds for the Company to terminate this Agreement for "Cause" shall include the occurrence of any of the following events: 5.1.1 EMPLOYEE's willful misconduct or gross negligence in the performance of his duties hereunder; 5.1.2 EMPLOYEE's willful failure or refusal to perform in the usual manner at the usual time those duties which he regularly and routinely performs in connection with the business of the Company or such other duties reasonably related to the capacity in which he is 5 employed hereunder which may be assigned to him by the Board of Directors of the Company, if such failure or refusal has not been substantially cured to the satisfaction of the Board of Directors within thirty (30) days after written notice of such failure or refusal has been given by the Company to EMPLOYEE. 5.1.3 EMPLOYEE's performance of any action when specifically instructed not to do so by the Chief Executive Officer of the Company unless specifically requested by the Board of Directors; 5.1.4 EMPLOYEE's engaging or in any manner participating in any activity which is directly competitive with or intentionally injurious to the Company or which violates any provision of Section 7; 5.1.5 EMPLOYEE's commission of any fraud against the Company or use or appropriation for his personal use or benefit of any funds or properties of the Company not authorized by the Board of Directors to be so used or appropriated; or 5.1.6 EMPLOYEE's conviction of any crime involving moral turpitude. Any notice of termination given pursuant to this Section 5.1 shall effect termination as of the date specified in such notice or, in the event no such date is specified, on the last day of the month in which such notice is delivered. 5.2 The Company may voluntarily terminate this Agreement without Cause by giving not less than thirty (30) days written notice to EMPLOYEE, provided, however, in no event shall such termination without Cause be earlier than six (6) months from the effective date of this Agreement. Any such notice shall specify the exact date of termination (the "Termination Date"). If EMPLOYEE's employment under this Agreement is terminated by the Company without Cause (as defined herein), EMPLOYEE shall be entitled to receive (i) his Base Salary 6 and other then current benefits for six (6) months, at the rate existing at the date of termination, and (ii) fifty percent (50%) of the stock options which are not vested on the Termination Date as such stock options are described on Exhibit A hereof, and said fifty percent (50%) of the unvested options shall vest on the Termination Date. All such Base Salary payments shall be paid over time in accordance with the Company's general payroll practices, as and when such Base Salary would have been paid had EMPLOYEE's employment not terminated. 5.3 EMPLOYEE may voluntarily terminate this Agreement upon no less than sixty (60) days written notice of such termination submitted to the Board of Directors, and in such event EMPLOYEE shall be entitled to receive all amounts due to him through the date of termination, provided that EMPLOYEE shall not be entitled to terminate this Agreement unless and until the Technology and other assets described in the Technology Transfer Term Sheet dated February 25, 2000 (the "Term Sheet") are fully, completely and properly transferred to the Company to the satisfaction of the Chief Executive Officer or the Board of Directors. 5.4 This Employment Agreement is a personal services contract whereby the Company is engaging the exclusive services of EMPLOYEE. By entering into this Agreement, the Company is relying on EMPLOYEE's performing his services for the Company throughout the entire term of this Agreement. 5.5 This Agreement shall terminate without notice upon the date of EMPLOYEE's death or the date when EMPLOYEE becomes "completely disabled" as that term is defined in Section 6.1. 5.6 In the event of EMPLOYEE's death, all rights of EMPLOYEE to compensation hereunder shall automatically terminate immediately upon his death, except that EMPLOYEE's heirs, personal representatives or estate shall be entitled to any unpaid portion of his salary and 7 accrued benefits earned up to the date of his death, and may exercise within six months of the date of death, all vested options to acquire the common stock of the Company granted to EMPLOYEE hereunder unless a longer term is provided for in the Company's Incentive Stock Option Plan. 5.7 In the event EMPLOYEE is disabled, EMPLOYEE shall be entitled to receive such disability benefits as would apply to other senior executives in the Company, subject to the terms and conditions of any such Company disability program. 5.8 If this Agreement is terminated pursuant to Sections 5.1 or 5.2, or EMPLOYEE gives the notice described in Section 5.3, the Chief Executive Officer or the Board of Directors of the Company may, in his or its sole discretion, relieve EMPLOYEE of his duties under this Agreement and assign EMPLOYEE other duties and responsibilities to be performed until the termination becomes effective. 6 Death or Disability During Term of Employment. --------------------------------------------- 6.1 The term "completely disabled" as used in this Agreement shall mean the inability of EMPLOYEE to perform his duties under this Agreement because he has become permanently disabled within the meaning of any policy of disability income insurance covering employees of the Company then in force. In the event the Company has no policy of disability income insurance covering employees of the Company in force when EMPLOYEE becomes disabled, the term "completely disabled" shall mean the inability of EMPLOYEE to perform his normal and customary duties under this Agreement for a total of six (6) consecutive months by reason of any incapacity, physical or mental, which the Board of Directors of the Company, based upon medical advice or an opinion provided by a licensed physician acceptable to the Board of Directors of the Company, determines to have incapacitated EMPLOYEE from satisfactorily 8 performing all of his usual services for the Company during the foreseeable future. The action of the Board of Directors of the Company shall be final and binding and the date such action is taken shall be the date of such complete disability for purposes of this Agreement, and upon such date this Agreement shall become null and void and of no further force and effect, provided that EMPLOYEE may exercise within six months of the date of termination under this Section 6, all vested options to acquire the common stock of the Company granted to EMPLOYEE hereunder, provided that EMPLOYEE acknowledges that such options may then be considered nonqualified options and not incentive stock options pursuant to federal law unless a longer term is provided for in the Company's Incentive Stock Option Plan. 7 Proprietary and Confidential Information. ---------------------------------------- 7.1 EMPLOYEE, during the term of this Agreement, will have access to and become acquainted with various information of substantial value to the Company, including trade secrets, which is not old and generally not known in the industry, and which gives the Company an advantage over its competitors who do not know or use it, including, but not limited to, formulas, patterns, devices, software, patents, patent applications, software applications or algorithms, secret inventions, processes, techniques, designs, drawings, developments, equipment, prototypes, sales and customer information, customer and prospect lists, and business and financial information relating to the business, products, practices, and techniques of the Company (collectively, the "Confidential Information"). EMPLOYEE agrees to regard and preserve as confidential such Confidential Information obtained by EMPLOYEE from whatever source and will not, either during EMPLOYEE's employment or thereafter, publish or disclose any part of such Confidential Information in any manner at any time, or use such Confidential Information except on behalf of the Company, without the prior written consent of the Company. 9 Further, both during EMPLOYEE's employment and thereafter, EMPLOYEE will refrain from any acts or omissions that would reduce the value of such Confidential Information to the Company. All files, records, documents, drawings, specifications, equipment, computer disks and software, and other electronic media or similar items relating to the business of the Company, whether prepared by the EMPLOYEE or otherwise coming into EMPLOYEE's possession, shall remain the exclusive property of the Company. 7.2 Nonsolicitation. In order to protect the Confidential Information of the Company and avoid injury to the Company, EMPLOYEE represents and warrants and agrees that, for the longer of one year following the termination of EMPLOYEE's employment with the Company, or so long as EMPLOYEE is receiving any payments under Section 5.2. from Company: (a) EMPLOYEE will not directly or indirectly solicit the customers or demonstrably prospective customers of the Company to purchase products or services which are competitive with those of the Company; (b) EMPLOYEE will not directly or indirectly solicit or in any manner encourage employees of the Company to leave its employ; and (c) EMPLOYEE will not accept employment from or with any company which is directly competitive with the Business of the Company. Any breach by EMPLOYEE of this Section shall cause the immediate termination of all of Company's obligation to pay EMPLOYEE any amounts hereunder. 7.3 Disclosure of Inventions. EMPLOYEE agrees that he will promptly disclose in writing to the officials designated by the Company to receive such disclosures, complete information concerning each and every invention, discovery, improvement, device, design, apparatus, practice, process, method or product, whether EMPLOYEE considers them patentable 10 or not, made, developed, perfected, devised, conceived or first reduced to practice by EMPLOYEE, either solely or in collaboration with others, during the period of EMPLOYEE's employment by the Company, and up to and including a period of one (1) year after termination of EMPLOYEE's employment, whether or not during regular working hours, relating either directly to the business, products, practices or techniques of the Company, or to the Company's actual or demonstrably anticipated research or development, or resulting from any work performed by EMPLOYEE for the Company (collectively, "Inventions"). 7.4 Assignment of Inventions.

If no list is attached or the list is blank, it means that he has no inventions or improvements to list. 7.6 Right to Use or Publish.
