                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Participants and Administrator of the
RadiSys Corporation 401(k) Plan


In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the RadiSys Corporation 401(k) Plan (the Plan) at December 31, 2001 and 2000,
and the changes in net assets available for benefits for the year ended December
31, 2001 in conformity with accounting principles generally accepted in the
United States of America. These financial statements are the responsibility of
the Plan's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

RADISYS CORPORATION 401(K) PLAN
NOTES TO FINANCIAL STATEMENTS


1.   DESCRIPTION OF PLAN

     GENERAL
     The RadiSys Corporation 401(k) Plan (the Plan) was established by RadiSys
     Corporation (the Company) on January 1, 1989 to provide a means for savings
     and investment by employees for retirement purposes. Participation in the
     Plan, which is a defined contribution plan, is voluntary. Currently, all
     employees of the Company who are age twenty-one or older are eligible to
     participate in the Plan. Qualifying employees may begin to participate in
     the Plan on the date of employment with the Company. The Plan is subject to
     the provisions of the Employee Retirement Income Security Act of 1974
     (ERISA).

     Under the terms of a trust agreement between the Company and Putnam
     Corporate Services (the trustee), all investments of the Plan are held in a
     trust fund by the trustee. Certain accounting and other administrative
     services for the Plan are performed by Putnam Corporate Services. The Plan
     is administered by a committee composed of management employees of the
     Company.

     During 2001, the Company acquired Microware Systems Corporation. On October
     1, 2001, the Microware Systems Corporation 401(k) Plan was merged into the
     Plan. Participants in the Microware Systems Corporation 401(k) Plan
     transferred $3,495,725 of investment account balances into the Plan. On
     October 1, 2001, eligible Microware Systems Corporation employees were
     allowed to participate in the Plan under the current Plan document.

     On January 1, 2001, the Company began offering employer stock as an option
     for participants. Investments in employer stock amounted to $112,528 at
     December 31, 2001.

     The following description of the Plan provides only general information.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     CONTRIBUTIONS
     Participants may contribute up to 20% of annual compensation to the Plan as
     pre-tax contributions, subject to the maximum allowed by the Internal
     Revenue Code ($10,500 for the years ended December 31, 2001 and 2000,
     respectively). Participants may also contribute up to 5% of compensation on
     an after-tax basis, up to an annual maximum of $10,000. No more than 20% of
     annual compensation may be contributed in the aggregate between pre-tax and
     after-tax contributions. Participants may also contribute amounts
     representing distributions from other qualified defined-benefit or
     contribution plans. Taxes on these contributions are deferred under Section
     401(k) of the Internal Revenue Code. The employer may make discretionary
     matching contributions equal to a percentage of the amount of the salary
     deferral. Participants must complete 1,000 hours of service and be employed
     on the last day of the Plan year to share in the discretionary matching
     contribution. Participants direct the investment of their contributions
     into various investment options available within the Plan.

RADISYS CORPORATION 401(K) PLAN
NOTES TO FINANCIAL STATEMENTS, CONTINUED


1.   DESCRIPTION OF PLAN (CONTINUED)

     PARTICIPANT ACCOUNTS
     The account of each participant who meets Plan eligibility requirements and
     is employed as defined above is credited with the participant's
     contribution and an allocation of discretionary employer matching
     contributions. Allocations are based on participant earnings or account
     balances, as defined in the Plan. The benefit to which a participant is
     entitled is the benefit that can be provided from the participant's vested
     account.

     VESTING
     Participants are fully vested at all times in their own individual
     contributions, including earnings thereon. Vesting in the employer
     discretionary matching contribution is based on continuous years of service
     ranging from 1 to 3 years. Employees are automatically 100% vested upon
     death or disability. If an employee terminates before becoming fully
     vested, the unvested portion of his or her account is forfeited and such
     amount is used to reduce the employer discretionary matching contribution.
     Remaining amounts will be reallocated to the accounts of participants based
     on employees' proportionate contributions.

     PAYMENT OF BENEFITS
     One hundred percent (100%) of the employee's vested benefits, including his
     or her allocation of plan earnings, may be paid to the employee upon
     retirement, or prior to retirement, on death, disability, resignation, or
     discharge. The employee salary deferral pre-tax contribution accounts,
     including a pro rata share of investment earnings, may be withdrawn to the
     extent approved by the Plan's administrative committee because of financial
     hardship. Benefits shall be paid in a lump sum, as provided by the Plan.
     Terminated participants may keep their vested balance in the Plan subject
     to a minimum $5,000 threshold. Vested balances less than $5,000 are
     distributed to the participant as a lump sum distribution. The trustee
     distributes all such amounts.

     PARTICIPANT LOANS
     The Plan allows for loans up to 50% of the total vested value of a
     participant's account, but not more than $50,000, reduced by the highest
     outstanding loan balance from the previous 12 months. Loan terms range from
     one to five years, unless the loan qualifies as a home loan. The term for a
     home loan is not to exceed 15 years. The loans are secured by the balance
     in the participant's account and bear interest based upon the prime
     interest rate (as listed in the Wall Street Journal) at the time the loan
     is issued, plus 2%. Principal and interest are paid ratably through
     semi-monthly payroll deductions.

     FORFEITED ACCOUNTS
     At December 31, 2001 and 2000, forfeited nonvested accounts totaled $63,732
     and $86,484, respectively. These amounts are used to reduce future employer
     contributions.

RADISYS CORPORATION 401(K) PLAN
NOTES TO FINANCIAL STATEMENTS, CONTINUED


1.   DESCRIPTION OF PLAN (CONTINUED)

     ADMINISTRATION OF PLAN ASSETS
     The trustee of the Plan holds the Plan's assets. Certain administrative
     functions are performed by officers or employees of the Company or its
     subsidiaries. No such officer or employee receives compensation from the
     Plan. Recordkeeping expenses are paid directly by the Company.


2.   SUMMARY OF ACCOUNTING POLICIES

     BASIS OF ACCOUNTING
     The financial statements of the Plan are prepared under the accrual method
     of accounting and present the net assets available for plan benefits and
     changes in those net assets.

     USE OF ESTIMATES
     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts of assets and liabilities and disclosure of contingent assets and
     liabilities at the date of the financial statements and changes in net
     assets available for plan benefits during the reporting period. Actual
     results could differ from those estimates.

     INVESTMENT VALUATION AND INCOME RECOGNITION
     The Plan's investments in Putnam Corporate Services funds, employer stock
     and self-directed brokerage funds are stated at fair value, which is based
     on the quoted market price of the underlying investments. Participant loans
     are valued at cost, which approximates fair value.

     Purchases and sales of securities are recorded on a trade-date basis.
     Interest income is recorded on the accrual basis. Dividends are recorded on
     the ex-dividend date.

     PAYMENTS OF BENEFITS
     Benefits are recorded when paid.

     CONCENTRATION OF CREDIT RISK
     The Plan has short-term investments of cash in the form of money market
     funds, which may exceed depository insurance limits. The Plan makes such
     investments with high credit quality entities and has not incurred any
     credit related losses.

RADISYS CORPORATION 401(K) PLAN
NOTES TO FINANCIAL STATEMENTS, CONTINUED


2.   SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

     RISKS AND UNCERTAINTIES
     The Plan provides for investment options in various investment securities.
     Investment securities are exposed to various risks, such as interest rate,
     market and credit risk. Due to the level of risk associated with certain
     investment securities and the level of uncertainty related to changes in
     the value of investment securities, it is at least reasonably possible that
     changes in risks in the near term would materially affect participants'
     account balances and the amounts reported in the statement of net assets
     available for plan benefits and the statement of changes in net assets
     available for plan benefits.


3.   INVESTMENTS REPRESENTING GREATER THAN 5% OF NET ASSETS AVAILABLE FOR PLAN
     BENEFITS

     The following investments represented 5% or more of net assets available
     for plan benefits:

4.   PLAN TERMINATION

     Although it has not expressed any intent to do so, the Company has the
     right under the Plan to terminate the Plan subject to the provisions of
     ERISA. The Company may elect, at its discretion, to either make a complete
     distribution of the assets or to continue the trust created by the Plan and
     distribute benefits in such a manner as though the Plan had not been
     terminated.

NOTES TO FINANCIAL STATEMENTS, CONTINUED


5.   TAX STATUS

     The Internal Revenue Service has determined and informed the Company by a
     letter dated May 11, 1993 that the Plan is qualified and the trust
     established under the Plan is tax-exempt, under the appropriate sections of
     the Code. The Plan has been amended since receiving the determination
     letter. However, the Plan Administrator and the Plan's tax counsel believe
     that the Plan is currently designed and being operated in compliance with
     the applicable requirements of the Code. Therefore, they believe that the
     Plan was qualified and the related trust was tax-exempt as of December 31,
     2001.


6.   RELATED-PARTY TRANSACTIONS

     Certain Plan investments are shares of mutual funds managed by the trustee.
     These transactions qualify as party-in-interest. Fees paid by the Plan to
     the trustee for investment management services amounted to $715 for the
     year ended December 31, 2001.
