Executive and the Company acknowledge that either party may terminate this employment relationship at any time and for any or no reason, provided that each party complies with the terms of this Agreement.

2.    Release of Claims. In consideration for and as a condition precedent to receiving the severance benefits outlined in this Agreement, Executive agrees to execute a Release of Claims in the form attached as Exhibit A ("Release of Claims"). Executive promises to execute and deliver the Release of Claims to the Company within 21 days (or, if required by applicable law, 45 days) from the last day of Executive's active employment. Executive shall forfeit the severance benefits outlined in this Agreement in the event that he fails to execute and deliver the Release of Claims to the Company in accordance with the timing and other provisions of the preceding sentence or revokes such Release of Claims prior to the "Effective Date" (as such term is defined in the Release of Claims) of the Release of Claims.

3.    Additional Compensation Upon Certain Termination Events.

3.1    Change of Control. In the event of a Termination of Executive's Employment (as defined in Section 6.1), and provided such Termination of Executive's Employment occurs within twelve (12) months following a Change of Control (as defined in Section 6.3 of this Agreement) or within three (3) months preceding a Change of Control, and contingent upon Executive's execution of the Release of Claims without revocation within the time period described in Section 2 above and compliance with Section 9, Executive shall be entitled to the following benefits:

(a)    As severance pay and in lieu of any other compensation for periods subsequent to the date of termination, the Company shall pay Executive, in a lump sum, an amount equal to nine (9) months of Executive's annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Severance pay that is payable under this Agreement shall be paid to Executive within 5 days following the Effective Date of the Release of Claims, and no later than two and one-half months following the last day of the calendar year of the Termination of Executive's Employment.

(b)    As an additional severance benefit, the Company will provide Executive with up to nine (9) months of continued coverage (100% paid by the Company) pursuant to COBRA under the Company's group health plan at the level of benefits (whether single or family coverage) previously elected by Executive immediately before the Termination of Executive's Employment and to the extent that Executive elects to continue coverage during such 9-month period. Each month for which the Company pays COBRA premiums directly reduces the total number of months of Executive’s COBRA continuation entitlement.

(c)    The Company shall pay Executive his stock-based incentive compensation plan payout under the RadiSys Corporation Long Term Incentive Plan pursuant to the terms of and within the periods specified in the Long Term Incentive Plan and shall pay Executive his stock-based incentive compensation plan payout under each other stock-based incentive compensation plan maintained by the Company pursuant to the terms of and within the periods specified in each such other stock-based incentive compensation plan that may then be applicable. The

Company shall also pay Executive his cash-based incentive compensation plan payout earned but not yet received under each cash-based incentive compensation plan maintained by the Company, if any, for any performance period completed prior to the Termination of Executive's Employment. In addition, the Company shall pay Executive his cash-based incentive compensation plan payout for any then current performance period under each such cash-based incentive compensation plan, provided that such payout shall not exceed the payout at target performance, pro-rated through the date of the Termination of Executive's Employment. The amounts described in this Section (c), if any, shall be paid on the date Executive would otherwise have received each such payment if his employment had not been terminated and, in any event, no later than two and one-half months following the last day of the calendar year for which the cash-based incentive compensation plan payout was earned.

3.2    Parachute Payments. Notwithstanding the foregoing, if the total payments and benefits to be paid to or for the benefit of Executive under this Agreement (the "Payment") would cause any portion of those payments and benefits to be "parachute payments" as defined in Code Section 280G(b)(2), or any successor provision, the total payments and benefits to be paid to or for the benefit of Executive under this Agreement shall be reduced by the Company to the Reduced Amount. The "Reduced Amount" shall be either (x) the largest portion of the Payment that would otherwise result in no portion of the Payment being subject to the excise tax imposed by Code Section 4999 (the "Excise Tax") or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive's receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order: first by reducing or eliminating the portion of the Payment that is payable in cash, second by reducing or eliminating the portion of the Payment that is not payable in cash (other than Payments as to which Treasury Regulations Section 1.280G-1 Q/A – 24(c) (or any successor provision thereto) applies (“Q/A-24(c) Payments”)), and third by reducing or eliminating Q/A-24(c) Payments. In the event that any Q/A-24(c) Payment or acceleration is to be reduced, such Q/A-24(c) Payment shall be reduced or cancelled in the reverse order of the date of grant of the awards. The independent public accounting firm serving as the Company's auditing firm immediately prior to the effective date of the Change of Control (the "Accountants") shall make in writing in good faith, subject to the terms and conditions of this Section 3.2, all calculations and determinations under this Section, including the assumptions to be used in arriving at such calculations and determinations, whether any payments are to be reduced, and the manner and amount of any reduction in the payments. For purposes of making the calculations and determinations under this Section, the Accountants may make reasonable assumptions and approximations concerning the application of Code Sections 280G and 4999. Executive shall furnish to the Accountants and the Company such information and documents as the Accountants or the Company may reasonably request to make the calculations and determinations under this Section. The Company shall bear all fees and costs the Accountants may reasonably charge or incur in connection with any calculations contemplated by this Section. The Accountants shall provide its determination, together with detailed supporting calculations regarding any relevant matter, both to the Company and to Executive by no later than ninety (90) days following the Termination of Executive's Employment.

4.    Withholding; Subsequent Employment.

4.1    Withholding. All payments provided for in this Agreement are subject to applicable withholding obligations imposed by federal, state and local laws and regulations.

4.2    Offset. The amount of any payment provided for in this Agreement shall not be reduced, offset or subject to recovery by the Company by reason of any compensation earned by Executive as the result of employment by another employer after termination.

5.    Other Agreements. Any cash severance pay paid to Executive under any other agreement with the Company or any of its subsidiaries or affiliates (including but not limited to any employment agreement, but excluding for this purpose any stock option, stock appreciation right, restricted stock, restricted stock unit, performance share, performance unit or other similar award agreement that may provide for accelerated vesting or related benefits) shall reduce the amount of cash severance pay payable under this Agreement.

6.    Definitions.

6.1    Termination of Executive's Employment. Termination of Executive's Employment means that (i) the Company has terminated Executive's employment with the Company (including any subsidiary of the Company) other than for Cause (as defined in Section 6.2), death or Disability (as defined in Section 6.4), or (ii) Executive, by written notice to the Company, has terminated his employment with the Company (including any subsidiary of the Company) for Good Reason (as defined below). For purposes of this Agreement, "Good Reason" means:

(a)    a material reduction by the Company or the surviving company in Executive's base pay from the highest annual rate in effect at any time within the 12-month period preceding the Change of Control, other than a salary reduction that is part of a general salary reduction affecting employees generally; or

(b)    a material change in the geographic location where Executive is based, provided that such change is more than 25 miles from where Executive's office is located immediately prior to the Change of Control, except for required travel on Company business to an extent substantially consistent with the business travel obligations which Executive undertook on behalf of the Company immediately prior to the Change of Control.

An event described above will not constitute Good Reason unless Executive provides written notice to the Company of Executive's intention to resign for Good Reason and specifying in reasonable detail the breach or action giving rise thereto within 90 days of its initial existence and the Company does not cure such breach or action within 30 days after the date of Executive's notice. In no instance will a resignation by Executive be deemed to be for Good Reason if it is made more than 12 months following the initial occurrence of any of the events that otherwise would constitute Good Reason hereunder.

A Termination of Executive's Employment is intended to mean a termination of employment which constitutes a "separation from service" under Code Section 409A. If any payments are to be made within a specified period of time or during a calendar year, the date of such payment shall be in the sole discretion of the Company, and Executive shall not be permitted, directly or indirectly, to designate the taxable year of payment.

6.2    Cause. Termination of Executive's Employment for "Cause" shall mean termination upon (a) the willful and continued failure by Executive to perform substantially Executive's reasonably assigned duties with the Company (other than any such failure resulting from Executive's incapacity due to physical or mental illness) after a demand for substantial performance is delivered to Executive by the Chief Executive Officer or the President of the Company, which specifically identifies the manner in which the Chief Executive Officer or the President of the Company believes that Executive has not substantially performed Executive's duties or (b) the willful engaging by Executive in illegal conduct which is materially and demonstrably injurious to the Company. No act, or failure to act, on Executive's part shall be considered "willful" unless done, or omitted to be done, by Executive without reasonable belief that Executive's action or omission was in, or not opposed to, the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board of Directors shall be conclusively presumed to be done, or omitted to be done, by Executive in the best interests of the Company.

6.3    Change of Control. A Change of Control shall mean that one of the following events has taken place:

(a)    The shareholders of the Company approve one of the following:

(i)    Any merger or statutory plan of exchange involving the Company ("Merger") in which the Company is not the continuing or surviving corporation or pursuant to which Common Stock would be converted into cash, securities or other property, other than a Merger involving the Company in which the holders of Common Stock immediately prior to the Merger continue to represent more than 50 percent of the voting securities of the surviving corporation after the Merger; or

(ii)    Any sale, lease, exchange, or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Company.

(b)    A tender or exchange offer, other than one made by the Company, is made for Common Stock (or securities convertible into Common Stock) and such offer results in a portion of those securities being purchased and the offeror after the consummation of the offer is the beneficial owner (as determined pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), directly or indirectly, of securities representing more than 50 percent of the voting power of outstanding securities of the Company.

(c)    The Company receives a report on Schedule 13D of the Exchange Act reporting the beneficial ownership by any person, or more than one person acting as a group, of securities representing more than 50 percent of the voting power of outstanding securities of the Company, except that if such receipt shall occur during a tender offer or exchange offer described in (b) above, a Change of Control shall not take place until the conclusion of such offer.

Notwithstanding anything in the foregoing to the contrary, no Change of Control shall be deemed to have occurred for purposes of this Agreement by virtue of any transaction which results in Executive, or a group of persons which includes Executive, acquiring, directly or indirectly, securities representing 20 percent or more of the voting power of outstanding securities of the Company.

6.4    Disability. "Disability" means Executive's absence from Executive's full-time duties with the Company for 180 consecutive calendar days as a result of Executive's incapacity due to physical or mental illness, as determined by Executive’s attending physician and in accordance with the Company’s Medical Leave of Absence Policy, unless within 30 days after notice of termination by the Company following such absence Executive shall have returned to the full-time performance of Executive's duties. This Agreement does not apply if the Executive is terminated due to Disability.

7.    Successors; Binding Agreement. This Agreement shall be binding on and inure to the benefit of the Company and its successors and assigns. This Agreement shall inure to the benefit of and be enforceable by Executive and Executive's legal representatives, executors, administrators and heirs.

8.    Entire Agreement. The Company and Executive agree that the foregoing terms and conditions constitute the entire agreement between the parties relating to the termination of Executive’s employment with the Company under the conditions described in Section 3.1, that this Agreement supersedes and replaces any prior agreements relating to the matters covered by this Agreement, specifically the Employee Severance Agreement, and that there exist no other agreements between the parties, oral or written, express or implied, relating to any matters covered by this Agreement. Further, Executive agrees to waive any entitlement to any severance or other payment under any such agreement and that such waiver shall inure to the benefit of the Company, its successors and assigns, and any third parties.

9.    Resignation of Corporate Offices; Reasonable Assistance. Executive will resign Executive's office, if any, as a director, officer or trustee of the Company, its subsidiaries or affiliates and of any other corporation or trust of which Executive serves as such at the request of the Company, effective as of the date of termination of employment. Executive further agrees that, if requested by the Company or the surviving company following a Change of Control, Executive will continue his employment with the Company or the surviving company for a period of up to six months following the Change of Control in any capacity requested, consistent with Executive's area of expertise, provided that Executive receives the same salary and substantially the same benefits as in effect prior to the Change of Control. Executive agrees to provide the Company such written resignation(s) and assistance upon request and that no severance pay or other benefits will be paid until after such resignation(s) or services are provided.

10.    Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of Oregon, without regard to its conflicts of laws provisions.

11.    Amendment. No provision of this Agreement may be modified unless such modification is agreed to in writing signed by Executive and the Company.

12.    Severability. If any of the provisions or terms of this Agreement shall for any reason be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other terms of this Agreement, and this Agreement shall be construed as if such unenforceable term had never been contained in this Agreement.

13.    Code Section 409A. This Agreement and the severance pay and other benefits provided hereunder are intended to qualify for an exemption from Code Section 409A, provided, however, that if this Agreement and the severance pay and other benefits provided hereunder are not so exempt, they are intended to comply with Code Section 409A to the extent applicable thereto. Notwithstanding any provision of this Agreement to the contrary, this Agreement shall be interpreted and construed consistent with this intent, provided that the Company shall not be required to assume any increased economic burden in connection therewith. Although the Company intends to administer this Agreement so that it will comply with the requirements of Code Section 409A, the Company does not represent or warrant that this Agreement will comply with Code Section 409A or any other provision of federal, state, local, or non-United States law. Neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers shall be liable to Executive (or any other individual claiming a benefit through Executive) for any tax, interest, or penalties Executive may owe as a result of compensation paid under this Agreement, and the Company and its subsidiaries shall have no obligation to indemnify or otherwise protect Executive from the obligation to pay any taxes pursuant to Code Section 409A. If any payment or reimbursement, or portion thereof, under this Agreement would be deemed to be a deferral of compensation not exempt from the provisions of Code Section 409A and would be considered a payment upon a separation from service for purposes of Code Section 409A, and Executive is determined to be a "specified employee" under Code Section 409A, then any such payment or reimbursement, or portion thereof, shall be delayed until the date that is the earlier to occur of (i) Executive's death or (ii) the date that is six months and one day following the date of the Termination of Executive's Employment (the "Delay Period"). Upon the expiration of the Delay Period, the payments delayed pursuant to this Section 13 shall be paid to Executive in a lump sum, and any remaining payments due under this Section 13 shall be payable in accordance with their original payment schedule.

14.    Costs and Attorneys' Fees. In the event of any administrative or civil action brought by Executive to enforce the provisions of this Agreement, the Company shall pay Executive's reasonable attorneys' fees through trial and/or on appeal. The payment or reimbursement of expenses described in this Section 14 shall be made promptly and in no event later than December 31 of the year following the year in which such expenses were incurred, and the amount of such expenses eligible for payment or reimbursement in any year shall not affect the amount of such expenses eligible for payment or reimbursement in any other year nor shall such right to payment or reimbursement be subject to liquidation or exchange for another benefit.

15.    Prohibition on Acceleration of Payments. The time or schedule of any payment or amount scheduled to be paid pursuant to the terms of this Agreement may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder.
