RECITALS:

A.    The Company wishes to obtain the services of the Executive for at least 
the duration of this Agreement, and the Executive wishes to provide his 
services for such period, all upon the terms and conditions set out in 
this Agreement.

B.    It is expressly recognized by the parties that the Executive's 
continuance in the Executive's position with the Company and agreement to be 
bound by the terms of this Agreement represents a substantial commitment to 
the Company in terms of the Executive's personal and professional career 
and a foregoing of present and future career options by the Executive, 
for all of which the Company receives substantial value. 

C.    The parties recognize that a Change of Control (as defined below) may 
result in material alteration or diminishment of the Executive's 
position and responsibilities and substantially frustrate the purpose of 
the Executive's commitment to the Company and forbearance of career 
options. 

D.    The parties recognize that in light of the above-described commitment 
and forbearance of career options, it is essential that, for the benefit 
of the Company and its stockholders, provision be made for a Change of 
Control Termination (as defined below) in order to enable the Executive 
to accept and effectively continue in the Executive's position in the 
face of inherently disruptive circumstances arising from the possibility 
of a Change of Control, although no such change is now contemplated or 
foreseen.

which is hereby acknowledged, the parties agree as follows:

termination, a lump sum amount equal to six (6) month's Base Salary.

then, in addition to the payments specified in said Section, the Company 
shall pay to the Executive bonuses, if any, as follows:

annual bonus or annual incentive, if any, to which the Executive 
would otherwise have become entitled under any Company bonus or 
incentive plan in effect at the time of termination of this 
Agreement had the Executive remained continuously employed for the 
full fiscal year in which termination occurred and continued to 
perform his duties in the same manner as they were performed 
immediately prior to termination; provided, however, that such 
bonus or incentive amount shall be pro-rated to the date of 
termination.  The amount payable pursuant to this Section 4.3.2.1 
shall be earned and payable as of the date that is fifteen (15) 
days after the date such bonus would have been paid had the 
Executive remained employed for the full fiscal year.

    4.3.2.2 In the event Executive would have been entitled to a 
quarterly bonus or quarterly incentive payment had he remained 
employed for the entire quarter in which Executive was terminated, 
the Company shall pay Executive such quarterly bonus or incentive 
amount pro-rated to the date of termination, payable as of the date 
that is fifteen (15) days after the date such bonus would have been 
paid had the Executive remained employed for the full quarter.

Executive's employment shall terminate in the event of death or Disability of 
the Executive.

Salary shall be terminated as of the final day of the fifth month 
referenced in the definition of "Disability."  Unless otherwise 
disqualified by the disability benefit program provider, this Section is

disability benefits from any other disability program in which the 
Executive may be enrolled or otherwise for which he is qualified at the 
time of disability. 

  4.4.3 In the event of termination by reason of the Executive's death or 
Disability, the Company shall pay to the Executive an amount equal to the 
amount the Executive would have received in incentive plan bonus for the 
year in which termination occurred had "target" goals been achieved, 
provided, however, that such amount shall be pro-rated to the date of 
termination.  This amount shall be earned and payable as of the date that 
is fifteen (15) days after the date such bonus would have been paid had 
the Executive remained employed for the full fiscal year in which 
termination occurred. 

4.5  CONTINUATION OF BENEFITS.  In the event of termination of Executive's 
employment by the Company pursuant to Section 4.3.1 or termination due to 
Disability, the Company shall pay the applicable premiums for such group health 
plan continuation as Executive is entitled to under the Consolidated Omnibus 
Reconciliation Act of 1985 ("COBRA") and shall continue such payment for the 
period of time the Executive is entitled to continue such coverage under COBRA. 

4.6  ENTIRE TERMINATION PAYMENT.  The compensation provided for in this 
Article 4 shall constitute the Executive's sole remedy for termination pursuant 
to this Article.  The Executive shall not be entitled to any other termination 
or severance payment which may be payable to the Executive under any other 
agreement between the Executive and the Company preceding or following the date 
of termination.

                    CONFIDENTIALITY; CONFLICT OF INTEREST

5.1  PROPRIETARY INFORMATION.   Executive shall keep confidential, except as 
the Company may otherwise consent in writing, and not disclose or make any use 
of except for the benefit of the Company, at any time either during or 
subsequent to his employment by the Company, any Proprietary Information which 
he may produce, obtain or otherwise acquire during the course of his 
employment.  As used herein, "Proprietary Information" shall include any trade 
secrets, confidential information, knowledge, data, or other information of the 
Company relating to products, processes, know-how, designs, formulae, test 
procedures and results, customer lists, business plans, marketing plans and 
strategies, and pricing strategies, or other subject matter pertaining to any 
business of the Company for any of its clients, customers, consultants, 
licensees of affiliates, which information is not in the public domain at the 
time of the alleged breach.  In the event of the termination of the Executive's 
employment for any reason whatsoever, Executive shall promptly return all 
records, materials, equipment, drawings and the like pertaining to any 
Proprietary Information. 

5.2 COVENANT NOT TO COMPETE.  Executive acknowledges that he will provide 
special skills, and acquire special information, regarding the activities of 
the Company.  Executive agrees, therefore, that he will not, for a period of 
twelve (12) months from and after the date he ceases to be employed by the 
Company, join, control or participate in the ownership, management, operation 
or control of or be connected with, any business located in the United States 
of America whose commercial products are in direct competition with the Company 
or which is developing products which will be in direct competition with the 
Company, in such a manner and position that he would likely use Proprietary 
Information, unless released from such obligation by the Board of Directors of 
the Company.  Executive agrees that he shall be deemed to be connected with a 
business if such a business is carried on by a partnership in which he is a 
general or limited partner or employee of a corporation or association of which 
he is a shareholder, officer, director, employee, member, consultant or agent; 
provided, that nothing herein shall prohibit the purchase or ownership by him 
of shares of less than five percent (5%) in a publicly or privately held 
corporation.  Executive agrees to submit a list of such business interests in 
Exhibit A attached hereto and incorporated by reference herein. 
Notwithstanding the foregoing, this Section 5.2 shall not apply to the 
Executive if the Executive's employment was terminated pursuant to Section 4.3 
or Section 6.1.2.1 of this agreement.

5.3  CONSENT TO INJUNCTION.  Executive agrees that the Company will or would 
suffer an irreparable injury if Executive were to compete with the business of 
the Company or any of its subsidiaries in violation of this Agreement and that 
the Company would by reason of such competition be entitled to injunctive 
relief in a court of appropriate jurisdiction and Executive stipulates to the 
entering of such injunctive relief prohibiting him from competing with the 
Company or any present affiliate of the Company in connection with the business 
of the Company, in violation of this Agreement. 

5.4  SEVERABILITY.  The parties intend that the covenants contained in Section 
5.2 be deemed to be separate covenants as to each county and state, and that if 
in any judicial proceeding a court shall refuse to enforce all of the separate 
covenants included herein because, taken together, they cover too extensive a 
geographic area or because any one includes too large an area or because they 
cover too large a period of time, the parties intend that such covenants shall 
be reduced in scope to the extent required by law or, if necessary, eliminated 
from the provisions hereof, and that all of the remaining covenants hereof not 
so affected shall remain fully effective and enforceable. 

5.5  ASSIGNMENT OF INVENTIONS.  As used in this Agreement, "inventions" shall 
include, but not be limited to, ideas, improvements, designs, and discoveries. 
 Executive hereby assigns and transfers to the Company entire right, title and 
interest in and to all inventions whether or not conceived by Executive

his employment with the Company which relate in any manner to the actual or 
demonstrably anticipated business, work, or research an development of the 
Company or its subsidiaries, or result from or are suggested by any tasks 
assigned to Executive or any work performed by Executive for or on behalf of 
the Company or its subsidiaries.  Executive agrees that all such inventions are

with any invention as defined in Section 5.5, above: 

  5.6.1 Executive will disclose such invention promptly in writing to the

applicable state law, in order to permit the Company to claim rights to 
which it may be entitled under this Agreement.  Such disclosure shall be 
received in confidence by the Company.
 
  5.6.2 Executive will, at the Company's request, promptly execute a 
written assignment of title to the Company for any invention required to 
be assigned by Section 5.5 ("assignable invention") and Executive will 
preserve any such assignable invention as confidential information of the 
Company; and

  5.6.3 Upon request, Executive agrees to assist the Company or its nominee 
(at its expense) during and at any time subsequent to his employment in 
every reasonable way to obtain for its own benefit patents and copyrights 
for such assignable inventions in any and all countries, which inventions 
shall be and remain the sole and exclusive property of the Company or its 
nominee, whether or not patented or copyrighted.  Executive agrees to 
execute such papers and perform such lawful acts as the Company deems to 
be necessary to allow it to exercise all right, title, and interest in 
such patents and copyrights.

time may have agreements with other persons or with the U.S. Government, or 
agencies thereof, which impose obligations or restrictions on the Company 
regarding inventions made during the course of work thereunder or regarding the 
confidential nature of such work.  Executive agrees to be bound by all such 
obligations and restrictions and to take all action necessary to discharge the 
obligations of the Company thereunder. 

5.9  TRADE SECRETS OF OTHERS.  Executive represents that his performance  of 
all the terms of this Agreement and as an employee of the Company such 
employment does not and will not breach any agreement to keep in confidence 
proprietary information, knowledge, or data acquired by Executive in confidence 
or in trust prior to his employment with the Company.  Executive will not 
disclose to the Company, or induce the Company to use, any confidential or 
proprietary information or material belonging to any previous employer or 
others.  Executive agrees not to enter into any agreement either written or 
oral in conflict herewith.

Executive will engage in no activity or employment which may conflict with the 
interest of the Company and will comply with the Company's policies and 
guidelines pertaining to business conduct and ethics.

that as of the date of this Agreement, he has fully complied with the terms of 
the Confidentiality Agreement.  Executive's obligations under this Agreement

cannot be settled by reasonable discussion, the parties agree that, prior to 
commencing any arbitration proceeding as contemplated by Section 7.6 they will 
first engage the services of a professional mediator agreed upon by the parties 
and attempt in good faith to resolve the dispute through confidential non-
binding mediation.  Each party shall bear one-half (1/2) of the mediator's fees 
and expenses and shall pay all of its own attorneys' fees and expenses related 
to the mediation. 

7.6  ARBITRATION.  Any dispute concerning the interpretation, construction, 
breach or enforcement of this Agreement or arising in any way from Executive's 
employment with Company or termination of employment shall be submitted to 
final and binding arbitration.  Such arbitration is to be before a single 
arbitrator in Portland, Oregon.  In the event the parties are unable to agree 
upon an arbitrator, an arbitrator shall be appointed by the court pursuant to 
ORS 36.320.  The arbitration shall be conducted pursuant to the rules of the 
American Arbitration Association ("AAA") Employment Dispute Resolution Rules.  
Executive and the Company agree that the procedures outlined in Section 7.5 and 
7.6 are the exclusive method of dispute resolution. 

7.7  ATTORNEY FEES.  If any action at law, in equity or by arbitration is 
taken to enforce or interpret the terms of this Agreement, the prevailing party 
shall be entitled to reasonable attorneys' fees, costs and necessary 
disbursements in addition to any other relief to which such party may be 
entitled, including fees and expenses on appeal. 

7.8  CONSTRUCTION.  Wherever possible, each provision of this Agreement shall 
be interpreted in such manner as to be effective and valid under applicable 
law, but if any provision of this Agreement shall be prohibited by or invalid 
under applicable law, such provision shall be ineffective only to the extent of 
such prohibition or invalidity without invalidating the remainder of such 
provision or the remaining provisions of this Agreement. 

7.9  WAIVERS.  No failure on the part of either party to exercise, and no 
delay in exercising, any right or remedy hereunder shall operate as a waiver 
thereof; nor shall any single or partial exercise of any right or remedy 
hereunder preclude any other or further exercise thereof or the exercise of 
any other right or remedy granted hereby or by any related document or by law. 

7.10  ASSIGNMENT.  This Agreement shall be binding upon and inure to the 
benefit of the Company and its successors and assigns, and shall be binding 
upon the Executive, his administrators, executors, legatees, and heirs.  In 
that this Agreement is a personal services contract, it shall not be assigned 
by the Executive. 

7.11  MODIFICATION.  This Agreement may not be and shall not be modified or 
amended except by written instrument signed by the parties hereto. 

7.12  ENTIRE AGREEMENT.  This Agreement together with the Confidentiality 
Agreement constitutes the entire agreement and understanding between the 
parties hereto in reference to all the matters herein agreed upon.  This 
Agreement replaces and supersedes all prior employment agreements or 
understandings of the parties hereto; provided, however, that the 
Confidentiality Agreement continues in full force and effect according to its 
terms. 

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be 
duly executed and delivered as of the day and year first above written.
