Exhibit 10.1
                               RADISYS CORPORATION
                        1996 EMPLOYEE STOCK PURCHASE PLAN
                        (As Amended through May 15, 2001)


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.

                                       1

         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 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.



                                       2

         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

                                       3

         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.

         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


                                       4

         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

         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


                                       5

         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

                                       6

         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 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.



                                       7

                  (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 1,750,000 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 1,750,000 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


                                       8

         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 officer or an Employee of the 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



                                       9

         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.




                                       10

XII.     STOCKHOLDER APPROVAL AND RULINGS

         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


                                       11

         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.

         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.








                                       12

         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.



                                       13

         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

         the Plan to be received by the Company prior to an Enrollment Date,

         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.
