                                AWARD AGREEMENT

      Pursuant to the terms of its 2005 Equity Incentive Plan (the "Plan"), F5
Networks, Inc., a Washington corporation (the "Company"), has granted you an
award (the "Award") (either a non-statutory stock option to purchase shares of
the Company's Common Stock (an "Option") or stock units representing the right
to receive shares of the Company's Common Stock ("Stock Units") as set forth in
the Notice of Grant of Stock Options or Stock Units (the "Grant Notice")) on the
terms and conditions as set forth in this 2005 Equity Incentive Plan Award
Agreement (this "Agreement"), the Grant Notice (which is incorporated herein by
reference) and the Plan (which is incorporated herein by reference). Capitalized
terms used but not defined in this Agreement shall have the meanings specified
in the Plan.

      IN CONSIDERATION OF THE MUTUAL PROMISES SET FORTH BELOW, THE PARTIES AGREE
AS FOLLOWS:

      1. GRANT OF AWARD;GRANT DATE. The Company has granted you an Award to
purchase (in the case of an Option) or to be issued (in the case of Stock Units)
the total number of shares of Common Stock of the Company as set forth in the
Grant Notice (the "Award Shares") on the terms and conditions set forth in this
Agreement, the Grant Notice and the Plan, including in the case of an Option at
the exercise price per share of Common Stock set forth in the Grant Notice (the
"Award Price"). The number and kind of Award Shares and the Award Price may be
adjusted in certain circumstances in accordance with Section 11 of the Plan.

      2. VESTING AND EXERCISE OR SETTLEMENT OF STOCK.

      2.1. Options.

            (a) The Option will vest and become exercisable during its term in
accordance with the vesting schedule set forth in the Grant Notice and with the
applicable provisions of the Plan and this Agreement. Vesting will cease upon
the termination of your Continuous Service except as otherwise set forth in the
Plan or this Agreement.

            (b) The vested and exercisable portion of the Option may be
exercised during its term (as set forth in Section 6) electronically as directed
by the Company or by delivering a Notice of Exercise (in a form designated by
the Company), together with the Award Price (payable in the manner set forth in
Section 3) to the Secretary of the Company, or to such other person as the
Company may designate, during regular business hours, together with such
additional documents as the Company may then require.

            (c) By exercising the Option, you agree that, as a condition to any
exercise of the Option, the Company may require you to enter an arrangement
providing for the payment by you to the Company of any tax withholding
obligation of the Company arising by reason of (1) the exercise of the Option or
(2) the disposition of shares acquired upon such exercise.

            2.2. Stock Units. On each date that Stock Units vest (a "Vesting
Date"), the Stock Units will be settled as to the number of shares vesting on
such Vesting Date, meaning that the Company will (subject to your obligations to
satisfy the requirements of Sections 5 and 9) issue to you the number of shares
vesting on such Vesting Date and the Award will thereafter remain in effect only
as to the number of unvested shares of Common Stock remaining subject thereto.
The shares of Common Stock issued upon conversion of Stock Units will be
registered in your name as of each Vesting Date on the register of shareholders
of the Company (through its transfer agent).

      3. METHOD OF PAYMENT OF THE OPENTION AWARD PRICE. Payment of the Award
Price is due in full upon exercise of all or any part of the Option. You may
elect to make payment of the Award Price by any of the methods, or combination
thereof, described in the Plan, provided that the Board may, in its sole
discretion, refuse to accept a particular form of consideration at the time of
exercise of any Option, or agree to accept any other form of legal
consideration.

<PAGE>

      4. WHOLE SHARE. The Award may only be exercised or settled for whole
shares.

      5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, the Award may not be exercised or settled unless the shares
issuable upon exercise or settlement of the Award are then registered under the
Securities Act or, if such shares are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise or settlement of the Award must
also comply with other applicable laws and regulations governing the Award, and
the Award may not be exercised or settled, and the Company will have no
liability for failure to issue shares of Common Stock upon exercise or
settlement of the Award, if the Company determines that the exercise or
settlement would not be in material compliance with such laws and regulations.

      6. TERM AND TERMINATION OF AWARD.

            6.1. Options. Subject to earlier termination as required under
Section 11 of the Plan, the term of the Option commences on the Grant Date and
expires upon the earliest of the following:

            (a) three (3) months after the termination of your Continuous
Service for any reason other than death or Disability, provided that if during
any part of such three-month period the Option is not exercisable solely because
of the condition set forth in Section 5, the Option shall not expire until the
earlier of the Expiration Date or until it shall have been exercisable for an
aggregate period of three (3) months after the termination of your Continuous
Service;

            (b) twelve (12) months after the termination of your Continuous
Service due to Disability;

            (c) eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates for reason other than Cause;

            (d) the Expiration Date indicated in the Grant Notice; or

            (e) the tenth (10th) anniversary of the Grant Date.

            6.2. Stock Units. In the event your Continuous Service terminates,
any Stock Units and the shares of Common Stock subject thereto (that have not
been issued upon settlement) shall be forfeited.

      7. TRANSFERABILITY. The Award is not transferable, except by will or by
the laws of descent and distribution. Options are exercisable during your life
only by you. Shares of Common Stock issued upon vesting of a Stock Unit are
issuable during your life only to you. Notwithstanding the foregoing, by
delivering written notice to the Company, in a form satisfactory to the Company,
you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise the Option or receive shares of Common Stock
issued upon vesting of a Stock Unit.

      8. NOT A SERVICE CONTRACT. This Agreement is not an employment or service
contract, and nothing in this Agreement shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company
or an Affiliate, or of the Company or an Affiliate to continue your employment.
In addition, nothing in this Agreement shall obligate the Company or an
Affiliate, their respective shareholders, Board, officers or employees to
continue any relationship that you might have as a director or consultant for
the Company or an Affiliate.

      9. WITHHOLDING OBLIGATIONS.

            9.1. At the time the Option is exercised, in whole or in part, or
shares of Common Stock are issued upon settlement of Stock Units or at any time
thereafter as requested by the Company, you hereby authorize withholding from
payroll and any other amounts payable to you, or otherwise agree to make
adequate provision for (including by means of a "cashless exercise" pursuant to
a program developed under Regulation T as promulgated by

<PAGE>

the Federal Reserve Board to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Company or an Affiliate, which arise in connection with the
Award.

            9.2. The Option is not exercisable and shares of Common Stock are
not issuable upon settlement of Stock Units unless the tax withholding
obligations of the Company are satisfied. Accordingly, you may not be able to
exercise the Option or receive shares of Common Stock upon settlement of Stock
Units when desired even though the Award is vested.

      10. PROFESSIONAL ADVICE. The acceptance and exercise or settlement of the
Award and the sale of Award Shares has consequences under federal and state tax
and securities laws which may vary depending upon your individual circumstances.
Accordingly, you acknowledge that you have been advised to consult your personal
legal and tax advisor in connection with this Agreement and your dealings with
respect to the Award and the Award Shares. You further acknowledge that the
Company has made no warranties or representations to you with respect to the
income tax consequences of the grant and exercise or settlement of the Award or
the sale of the Award Shares and you are in no manner relying on the Company or
its representatives for an assessment of such consequences.

      11. GOVERNING PLAN DOCUMENT. Your Award is subject to all applicable
provisions of the Plan, which are hereby made a part of your Award, and is
further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. In the

Plan, the provisions of the Plan shall control.

      12. DAMAGES. You shall be liable to the Company for all costs and damages,

direct the application of the laws of another jurisdiction.

                                                                    EXHIBIT 10.1

                               RADISYS CORPORATION
                        1996 EMPLOYEE STOCK PURCHASE PLAN
                        (AS AMENDED THROUGH MAY 17, 2005)

I. PURPOSE OF PLAN

      As a means by which Employees may share in the Company's growth and
success, RadiSys Corporation (the "Company") believes that ownership of shares
of its Common Stock by its Employees is desirable. To this end, and as an
incentive to better performance and improved profits, the Company has
established the RadiSys Corporation 1996 Employee Stock Purchase Plan (the
"Plan").

      The Company intends that the Plan will constitute an "employee stock
purchase plan" within the meaning of Section 423 of the Code.

II. DEFINITIONS

      Terms that are capitalized within this document shall have the meanings as
set forth in Exhibit A, unless otherwise specified within the text.

III. EMPLOYEE PARTICIPATION

      PARTICIPATION

      Subject to the provisions of this Section III, an Employee may elect to
participate in the Plan effective as of any Enrollment Date by completing and
filing a Payroll Deduction Authorization Form as provided in Section IV. As of
each Enrollment Date, the Company hereby grants a right to purchase Shares under
the terms of the Plan to each eligible Employee who has elected to participate
in the Offering commencing on that Enrollment Date.

      REQUIREMENTS FOR PARTICIPATION

      A person shall become eligible to participate in the Plan on the first
Enrollment Date on which that person meets the following requirements:

      a)    The person is an Employee, and

      b)    The person's customary period of Employment is more than twenty (20)
            hours per week.

      Any eligible Employee may enroll in the Plan as of the Enrollment Date of
any Offering by filing timely written notice of such participation, subject to
the following provisions:

      (i) In order to enroll in the Plan initially, an eligible Employee must
complete, sign and submit to the Company the following forms:

            (A) Payroll Deduction Authorization Form Must be received by the
      Company prior to 4:00 p.m., Pacific Time on the Enrollment Date of an
      Offering to be effective for that Offering.

            (B) ESPP New Account Form This form must accompany the Payroll
      Deduction Authorization Form submitted for enrollment in the Plan. An ESPP
      New Account Form must be received by the Company prior to 4:00 p.m.,
      Pacific Time on the Enrollment Date of an Offering to be effective for
      that Offering.

      (ii) A Participant in an ongoing Offering may elect as of any Enrollment
Date to enroll in the new Offering commencing on that Enrollment Date by filing
a Payroll Deduction Authorization Form making such election prior to 4:00 p.m.
Pacific Time on the Enrollment Date. An election by a current Participant to
enroll in a new Offering shall constitute a withdrawal, effective as of such

<PAGE>

Enrollment Date, from the ongoing Offering and simultaneous reenrollment in the
new Offering. A reenrollment shall not affect the purchase of Shares under the
ongoing Offering occurring on the Purchase Date immediately preceding the
Enrollment Date. A Participant may make an ongoing election to reenroll on any
Enrollment Date as of which the fair market value of the Shares for purposes of
Section VI is less than it was as of the Enrollment Date for the Offering in
which the Participant is currently participating. Unless otherwise specified by
the Participant, any such ongoing reenrollment election shall be subject to
revocation; provided, however, that to be effective to prevent reenrollment on
any Enrollment Date, such revocation must be received by the Company prior to
4:00 p.m. Pacific Time on the Enrollment Date.

      (iii) Absent withdrawal from the Plan pursuant to Section VII, a
Participant will automatically be re-enrolled in the Offering commencing on the
Enrollment Date immediately following the expiration of the Offering of which
that person is then a Participant.

      A Participant shall become ineligible to participate in the Plan and shall
cease to be a Participant when the Participant ceases to meet the eligibility
requirements as defined above.

      LIMITATIONS ON PARTICIPATION

      No Employee may obtain a right to purchase Shares under the Plan if,
immediately after the right is granted, the Employee owns or is deemed to own
Shares possessing five percent (5%) or more of the combined voting power or
value of all classes of stock of the Company or any parent or subsidiary of the
Company. For purposes of determining share ownership, the rules of Section
424(d) of the Code shall apply and Shares that the Employee may purchase under
any options or rights to purchase, whether or not Vested, shall be treated as
Shares owned by the Employee.

      No Employee may obtain a right to purchase Shares under the Plan that
permits the Employee's rights to purchase Shares under the Plan and any other
employee stock purchase plan within the meaning of Section 423 of the Code of
the Company or any parent or subsidiary of the Company to accrue at a rate which
exceeds $25,000 in fair market value of Shares (determined as of the Enrollment
Date) for each calendar year of the Offering. This section shall be interpreted
to permit an Employee to purchase the maximum number of Shares permitted under
Section 423(b)(8) of the Code and regulations and interpretations adopted
thereunder.

      The maximum number of Shares that an Employee may purchase in an Offering
shall not exceed 10,000 shares, no more than one-third of which may be purchased
on any Purchase Date on or prior to August 15, 2000, and no more than one-sixth
of which may be purchased on any Purchase Date after August 15, 2000.

      VOLUNTARY PARTICIPATION

      Participation in the Plan shall be strictly voluntary.

IV. PAYROLL DEDUCTIONS

      PAYROLL DEDUCTION AUTHORIZATION

      An Employee may contribute to the Plan only by means of payroll
deductions. A Payroll Deduction Authorization Form must be filed with the
Company's stock administrator prior to 4:00 p.m. Pacific Time on the Enrollment
Date as of which the payroll deductions are to take effect.

      AMOUNT OF DEDUCTIONS

      A Participant may specify that the person desires to make contributions to
the Plan at a rate not less than 1% and not more than 15% of the Compensation
paid to the Participant during each pay period in the Offering, or other such
minimum or maximum percentages as the Plan Administrator shall establish from
time to time; provided, however, that a Participant in any Offering that
commenced prior to August 15, 2000 may not specify during that Offering
contributions to the Plan of more than 10% of Compensation. Such specification
shall apply during any period of continuous participation in the Plan, unless
otherwise modified or terminated as provided in this Section IV or as otherwise
provided in the Plan. If a payroll deduction cannot be made in whole or in part
because the Participant's pay for the period in question is insufficient to fund
the deduction after having first withheld all other amounts deductible from that
person's pay, the amount that was not withheld cannot be made up by the
Participant nor will it be withheld from subsequent pay checks.

<PAGE>

      COMMENCEMENT OF DEDUCTIONS

      Payroll deductions for a Participant shall commence on the Enrollment Date
of the Offering for which that person's Payroll Deduction Authorization Form is
effective and shall continue indefinitely, unless modified or terminated as
provided in this Section IV or as otherwise provided in the Plan.

      ACCOUNTS

      All payroll deductions made for a Participant shall be credited to his or
her Account under the Plan. Following each Purchase Date, the Plan Administrator
shall promptly deliver a report to each Participant setting forth the aggregate
payroll deductions credited to such Participant's Account since the last
Purchase Date and the number of Shares purchased and delivered to the Custodian
for deposit into the Participant's Custodial Account.

      MODIFICATION OF AUTHORIZED DEDUCTIONS

      A Participant may at any time increase or decrease the amount of that
person's payroll deduction effective for all applicable payroll periods, by
completing an amended Payroll Deduction Authorization Form and filing it with
the Company's stock administrator in accordance with this Section IV; provided,
however, that a Participant in any Offering that commenced prior to August 15,
2000 may not change the amount of that person's payroll deduction more than
three times during that Offering.

      A Participant may at any time discontinue the Participant's payroll
deductions, without withdrawing from the Plan, by completing an amended Payroll
Deduction Authorization Form and filing it with the Company's stock
administrator. Previous payroll deductions will then be retained in the
Participant's Account for application to purchase Shares on the next Purchase
Date, after which the Participant's participation in the Offering and in the
Plan will terminate unless the participant has timely filed another Payroll
Deduction Authorization Form to resume payroll deductions.

      For purposes of the above, an amended Payroll Deduction Authorization form
shall be effective for a specific pay period when filed 7 days prior to the last
day of such payroll period; provided, however, that for a Participant in any
Offering that commenced prior to August 15, 2000 an amended Payroll Deduction
Authorization form shall be effective for a specific pay period during that
Offering when filed 15 days prior to the last day of such payroll period.

V. CUSTODY OF SHARES

      DELIVERY AND CUSTODY OF SHARES

      Shares purchased pursuant to the Plan shall be delivered to and held by
the Custodian.

      CUSTODIAL ACCOUNT

      As soon as practicable after each Purchase Date, the Company shall deliver
to the Custodian the full Shares purchased for each Participant's Account. The
Shares will be held in a Custodial Account specifically established for this
purpose. An Employee must open a Custodial Account with the Custodian in order
to be eligible to purchase Shares under the Plan. In order to open a Custodial
Account, the Participant must complete an ESPP New Account Form and file it with
the stock administrator prior to 4:00 p.m. Pacific Time on the Enrollment Date
of the Offering as of which the enrollment is to take effect; provided, however,
that an ESPP New Account Form that effects a change in the status of the
Custodial Account may be filed at any time during participation in the Plan.

      TRANSFER OF SHARES

      Upon receipt of appropriate instructions from a Participant on forms
provided for that purpose, the Custodian will transfer into the Participant's
own name all or part of the Shares held in the Participant's Custodial Account
and deliver such Shares to the Participant.

      STATEMENTS

<PAGE>

      The Custodian will deliver to each Participant a semi-annual statement
showing the activity of the Participant's Custodial Account and the balance as
to both Shares and cash. Participants will be furnished such other reports and
statements, and at such intervals, as the Custodian and Plan Administrator shall
determine from time to time.

VI. PURCHASE OF SHARES

      PURCHASE OF SHARES

      Subject to the limitations of Section VII, on each Purchase Date in an
Offering, the Company shall apply the amount credited to each Participant's
Account to the purchase of as many full Shares that may be purchased with such
amount at the price set forth in this Section VI, and shall promptly deliver
such Shares to the Custodian for deposit into the Participant's Custodial
Account. Payment for Shares purchased under the Plan will be made only through
payroll withholding deductions in accordance with Section IV.

      PRICE

      The price of Shares to be purchased on any Purchase Date shall be the
lower of:

      (a) Eighty-five percent (85%) of the fair market value of the Shares on
the Enrollment Date of the Offering; or

      (b) Eighty-five percent (85%) of the fair market value of the Shares on
the Purchase Date.

      FAIR MARKET VALUE

      The fair market value of the Shares on any date shall be equal to the
closing trade price of such shares on the Valuation Date, as reported on the
NASDAQ National Market System or such other quotation system that supersedes it.

      UNUSED CONTRIBUTIONS

      Any amount credited to a Participant's Account and remaining therein
immediately after a Purchase Date because it was less than the amount required
to purchase a full Share shall be carried forward in such Participant's Account
for application on the next succeeding Purchase Date.

VII. TERMINATION AND WITHDRAWAL

      TERMINATION OF EMPLOYMENT

      Upon termination of a Participant's Employment for any reason other than
death, the payroll deductions credited to such Participant's Account shall be
returned to the Participant. A Participant shall have no right to accrue Shares
upon termination of the person's Employment.

      TERMINATION UPON DEATH

      Upon termination of the Participant's Employment because of that person's
death, the payroll deductions credited to that person's Account shall be used to
purchase Shares as provided in Section VI on the next Purchase Date. Any Shares
purchased and any remaining balance shall be transferred to the deceased
Participant's Beneficiary, or if none, to that person's estate.

      DESIGNATION OF BENEFICIARY

      Each Participant may designate, revoke, and redesignate Beneficiaries. All
changes to designation of Beneficiary shall be in writing and will be effective
upon delivery to the Plan Administrator.

      WITHDRAWAL

      A Participant may withdraw the entire amount credited to that individual's
Account under the Plan and thereby terminate participation in the current
Offering at any time by giving written notice to the Company, but in no case may
a Participant withdraw accounts within the 15 days immediately preceding a
Purchase Date for the Offering. Any amount withdrawn shall be paid to the

<PAGE>

Participant promptly after receipt of proper notice of withdrawal and no further
payroll deductions shall be made from the person's Compensation unless a Payroll
Deduction Authorization Form directing further deductions is or has been
submitted.

      STATUS OF CUSTODIAL ACCOUNT

      Upon termination of a Participant's Employment for any reason other than
death, the Participant may,

      (a) Elect to retain with the Custodian the Shares held in the
Participant's Custodial Account. The Participant will bear the cost of any
annual fees resulting from maintaining such an account.

      (b) Request issuance of the Shares held in the Participant's Custodial
Account by submitting to the Custodian the appropriate forms provided for that
purpose.

      Upon termination of a Participant's Employment as a result of death, any
Shares held by the Custodian for the Participant's Account shall be transferred
to the person(s) entitled thereto under the laws of the state of domicile of the
Participant upon a proper showing of authority.

VIII. SHARES PURCHASED UNDER THE PLAN

      SOURCE AND LIMITATION OF SHARES

      The Company has reserved for sale under the Plan 4,150,000 shares of
common stock, subject to adjustment upon changes in capitalization of the
Company as provided in Section X. Shares sold under the Plan may be newly issued
Shares or Shares reacquired in private transactions or open market purchases,
but all Shares sold under the Plan regardless of source shall be counted against
the 4,150,000 Share limitation.

      If there is an insufficient number of Shares to permit the full exercise
of all existing rights to purchase Shares, or if the legal obligations of the
Company prohibit the issuance of all Shares purchasable upon the full exercise
of such rights, the Plan Administrator shall make a pro rata allocation of the
Shares remaining available in as nearly a uniform and equitable manner as
possible, based pro rata on the aggregate amounts then credited to each
Participant's Account. In such event, payroll deductions to be made shall be
reduced accordingly and the Plan Administrator shall give written notice of such
reduction to each Participant affected thereby. Any amount remaining in a
Participant's Account immediately after all available Shares have been purchased
will be promptly remitted to such Participant. Determination by the Plan
Administrator in this regard shall be final, binding and conclusive on all
persons. No deductions shall be permitted under the Plan at any time when no
Shares are available.

      DELIVERY OF SHARES

      As promptly as practicable after each Purchase Date, the Company shall
deliver to the Custodian the full Shares purchased for each Participant's
Account.

      INTEREST IN SHARES

      The rights to purchase Shares granted pursuant to this Plan will in all
respects be subject to the terms and conditions of the Plan, as interpreted by
the Plan Administrator from time to time. The Participant shall have no interest
in Shares purchasable under the Plan until payment for the Shares has been
completed at the close of business on the relevant Purchase Date. The Plan
provides only an unfunded, unsecured promise by the Company to pay money or
property in the future. Except with respect to the Shares purchased on a
Purchase Date, an Employee choosing to participate in the Plan shall have no
greater rights than an unsecured creditor of the Company. After the purchase of
Shares, the Participant shall be entitled to all rights of a stockholder of the
Company.

IX. ADMINISTRATION

      PLAN ADMINISTRATOR

      At the discretion of the Board of Directors, the Plan shall be
administered by the Board of Directors or by a Committee appointed by the Board
of Directors. Each member of the Committee shall be either a director, an

Company. Each member shall serve for a term commencing on a date specified by
the Board of Directors and continuing until that person dies, resigns or is
removed by the Board of Directors.

      POWERS

      The Plan Administrator shall be vested with full authority to make,
administer and interpret the rules and regulations as it deems necessary to
administer the Plan. Any determination, decision or act of the Plan
Administrator with respect to any action in connection with the construction,
interpretation, administration or application of the Plan shall be final,
binding and conclusive upon all Participants and any and all other persons
claiming under or through any Participant. The provisions of the Plan shall be
construed in a manner consistent with the requirements of Section 423 of the
Code.

X. CHANGES IN CAPITALIZATION, MERGER, ETC.

      RIGHTS OF THE COMPANY

      The grant of a right to purchase Shares pursuant to this Plan shall not
affect in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or other changes in its capital or business
structure or to merge, consolidate or dissolve, liquidate or transfer all or any
part of its divisions, subsidiaries, business or assets.

      RECAPITALIZATION

      Subject to any required action by stockholders, the number of Shares
covered by the Plan as provided in Section VIII and the price per Share shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares of the Company resulting from a subdivision or consolidation of Shares or
the payment of a stock dividend or any other increase or decrease in the number
of such Shares effected without receipt or payment of consideration by the
Company.

      CONSOLIDATION OR MERGER

      In the event of the consolidation or merger of the Company with or into
any other business entity, or sale by the Company of substantially all of its
assets, the successor may at its discretion continue the Plan by adopting the
same by resolution of its Board of Directors or agreement of its partners or
proprietors. If, within 90 days after the effective date of a consolidation,
merger, or sale of assets, the successor corporation, partnership or
proprietorship does not adopt the Plan, the Plan shall be terminated in
accordance with Section XIII.

XI. TERMINATION OF EMPLOYMENT

      LEAVE

      A person's Employment shall not terminate on account of an authorized
leave of absence or sick leave, or on account of a military leave described in
this Section XI, or a direct transfer between Employers, provided such leave
does not exceed 90 days or, if longer, so long as the person's right to
reemployment is guaranteed by statute or by contract. Failure to return to work
upon expiration of any leave of absence or sick leave shall be considered a
resignation effective as of the expiration of such leave of absence or sick
leave.

      MILITARY LEAVE

      Any Employee who leaves the Employer directly to perform services in the
Armed Forces of the United States or in the United States Public Health Service
under conditions entitling the Employee to reemployment rights provided by the
laws of the United States, shall be on military leave. An Employee's military
leave shall expire if the Employee voluntarily resigns from the Employer during
the leave or if that person fails to make an application for reemployment within
a period specified by such law for preservation of employment rights. In such
event, the individual's Employment shall terminate by resignation on the day the
military leave expires.

XII. STOCKHOLDER APPROVAL AND RULINGS

<PAGE>

      The Plan is expressly made subject to (a) the approval of the Plan within
twelve (12) months after the Plan is adopted by the stockholders of the Company
and (b) at the Company's election, to the receipt by the Company from the
Internal Revenue Service of a ruling in scope and content satisfactory to
counsel to the Company, affirming qualification of the Plan within the meaning
of Section 423 of the Code. If the Plan is not so approved by the stockholders
within 12 months after the date the Plan is adopted and if, at the election of
the Company a ruling from the Internal Revenue Service is sought but not
received on or before one year after this Plan's adoption by the Board of
Directors, this Plan shall not come into effect. In that case, the Account of
each Participant shall forthwith be paid to the Participant.

XIII. MISCELLANEOUS PROVISIONS

      AMENDMENT AND TERMINATION OF THE PLAN

      The Board of Directors of the Company may at any time amend the Plan.
Except as otherwise provided herein, no amendment may adversely affect or change
any right to purchase Shares without prior approval of the stockholders of the
Company if the amendment would:

      (i) Permit the sale of more Shares than are authorized under Section VIII;

      (ii) Permit the sale of Shares to employees of entities which are not
Employers;

      (iii) Materially increase the benefits accruing to Participants under the
Plan; or

      (iv) Materially modify the requirements as to eligibility for
participation in the Plan.

      The Plan is intended to be a permanent program, but the Company reserves
the right to declare the Plan terminated at any time. Upon such termination,
amounts credited to the Accounts of the Participants with respect to whom the
Plan has been terminated shall be returned to such Participants.

      NON-TRANSFERABILITY

      Neither payroll deductions credited to a Participant's Account nor any
rights with regard to the purchase of Shares under the Plan may be assigned,
transferred, pledged or otherwise disposed of in any way by the Participant
except as provided in Section VII, and any attempted assignment, transfer,
pledge, or other disposition shall be null and void. The Company may treat any
such act as an election to withdraw funds in accordance with Section VII. A
Participant's rights to purchase Shares under the Plan are exercisable during
the Participant's lifetime only by the Participant.

      USE OF FUNDS

      All payroll deductions received or held by the Company under the Plan may
be used by the Company for any corporate purposes and the Company shall not be
obligated to segregate the payroll deductions.

      EXPENSES

      All expenses of administering the Plan shall be borne by the Company. The
Company will not pay expenses, commissions or taxes incurred in connection with
sales of Shares by the Custodian at the request of a Participant. Expenses to be
paid by a Participant will be deducted from the proceeds of sale prior to
remittance.

      TAX WITHHOLDING

      Each Participant who has purchased Shares under the Plan shall immediately
upon notification of the amount due, if any, pay to the Employer in cash amounts
necessary to satisfy any applicable federal, state and local tax withholding
determined by the Employer to be required. If the Employer determines that
additional withholding is required beyond any amounts deposited at the time of
purchase, the Participant shall pay such amount to the Employer on demand. If
the Participant fails to pay the amount demanded, the Employer may withhold that
amount from other amounts payable by the Employer to the Participant, including
salary, subject to applicable law.

<PAGE>

      NO INTEREST

      No Participant shall be entitled, at any time, to any payment or credit
for interest with respect to or on the payroll deductions contemplated herein,
or on any other assets held hereunder for the Participant's Account.

      REGISTRATION AND QUALIFICATION OF SHARES

      The offering of Shares hereunder shall be subject to the effecting by the
Company of any registration or qualification of the Shares under any federal or
state law or the obtaining of the consent or approval of any governmental
regulatory body which the Company shall determine, in its sole discretion, is
necessary or desirable as a condition to, or in connection with, the offering or
the issue or purchase of the Shares covered thereby. The Company shall make
every reasonable effort to effect such registration or qualification or to
obtain such consent or approval.

      RESPONSIBILITY AND INDEMNITY

      Neither the Company, its Board of Directors, the Custodian, nor any
member, officer, agent or employee of any of them, shall be liable to any
Participant under the Plan for any mistake of judgment or for any omission or
wrongful act unless resulting from gross negligence, willful misconduct or
intentional misfeasance. The Company will indemnify and save harmless its Board
of Directors, the Custodian and any such member, officer, agent or employee
against any claim, loss, liability or expense arising out of the Plan, except
such as may result from the gross negligence, willful misconduct or intentional
misfeasance of such entity or person.

      PLAN NOT A CONTRACT OF EMPLOYMENT

      The Plan is strictly a voluntary undertaking on the part of the Employer
and shall not constitute a contract between the Employer and any Employee, or
consideration for or an inducement or a condition of employment of an Employee.
Except as otherwise required by law, or any applicable collective bargaining
agreement, nothing contained in the Plan shall give any Employee the right to be
retained in the service of the Employer or to interfere with or restrict the
right of the Employer, which is hereby expressly reserved, to discharge or
retire any Employee at any time, with or without cause and with or without
notice. Except as otherwise required by law, inclusion under the Plan will not
give any Employee any right or claim to any benefit hereunder except to the
extent such right has specifically become fixed under the terms of the Plan. The
doctrine of substantial performance shall have no application to any Employee,
Participant, or Beneficiary. Each condition and provision, including numerical
items, has been carefully considered and constitutes the minimum limit on
performance which will give rise to the applicable right.

      SERVICE OF PROCESS

      The Secretary of the Company is hereby designated agent for service or
legal process on the Plan.

      NOTICE

      All notices or other communications by a Participant to the Company under
or in connection with the Plan shall be deemed to have been duly given when
received by the Plan Administrator. Any notice required by the Plan to be
received by the Company prior to an Enrollment Date, payroll period or other
specified date, and received by the Plan Administrator subsequent to such date
shall be effective on the next occurring Enrollment Date, payroll period or
other specified date to which such notice applies.

      GOVERNING LAW

      The Plan shall be interpreted, administered and enforced in accordance
with the Code, and the rights of Participants, former Participants,
Beneficiaries and all other persons shall be determined in accordance with it.
To the extent state law is applicable, the laws of the State of Oregon shall
apply.
