AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

Exhibit 10.42

AMENDED AND RESTATED

EXECUTIVE SEVERANCE AGREEMENT

December 29, 2008

1. Employment Relationship. In order to induce Executive to become an employee of the Company, this Agreement sets forth the severance benefits that Company will provide to Executive in the event Executive’s employment by the Company is terminated under the circumstances described herein. Executive will be employed by the Company as Vice President and General Manager of the Communication Networking Business Unit. 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 Involuntary Termination.

3.1 Involuntary Termination . In the event of a Termination of Executive’s Employment (as defined in Section 5.1) other than for Cause (as defined in Section 5.2), death or Disability (as defined in Section 5.3), and contingent upon the approval of the Compensation Committee of the Company’s Board of Directors and Executive’s execution of the Release of Claims without revocation within the time period described in Section 2 above and compliance with Section 8, 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 six (6) months of Executive’s annual base pay at the rate in effect immediately prior to the date of termination; provided, such lump sum amount shall not exceed two times the lesser of (i) the sum of Executive’s annualized compensation based upon the annual rate of pay for services provided to the Company as an employee for the calendar year preceding the calendar year of the Termination of Executive’s Employment (adjusted for any increase during that year that was expected to continue indefinitely but for the Termination of Executive’s

Employment), or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the “Code”), or any successor provision, for the year of the Termination of Executive’s Employment. Severance pay that is payable under this Agreement shall be paid to Executive within 30 days following the “Effective Date” (as such term is defined in the Release of Claims) of the Release of Claims and in any event no later than the end of the second calendar year following the calendar year of the Termination of Executive’s Employment.

(b) As an additional severance benefit, the Company will provide Executive with up to six (6) months of continued coverage 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 6-month period.

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. Definitions.

5.1 Termination of Executive’s Employment. Termination of Executive’s Employment means that the Company has terminated Executive’s employment with the Company (including any subsidiary of the Company) other than for Cause (as defined in Section 5.2), death or Disability (as defined in Section 5.3). A Termination of Executive’s Employment is intended to mean a termination of employment which constitutes a “separation from service” under Code Section 409A.

5.2 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 Board of Directors, the Chief Executive Officer or the President of the Company which specifically identifies the manner in which the Board of Directors 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.

5.3 Disability. “Disability” means Executive’s absence from Executive’s full-time duties with the Company for 180 consecutive 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.

6. 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.

7. Entire Agreement. The Company and Executive agree that the foregoing terms and conditions constitute the entire agreement between the parties relating to the matters covered by this Agreement, that this Agreement supersedes and replaces any prior agreements relating to the matters covered by this Agreement, specifically the Executive Severance Agreement by and between Executive and the Company dated February 27, 2007, and that there exist no other agreements between the parties, oral or written, express or implied, relating to any matters covered by this Agreement.

8. Resignation of Corporate Offices. 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 agrees to provide the Company such written resignation(s) upon request and that no severance pay or other benefits will be paid until after such resignation(s) are provided.

9. 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.

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

11. 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.

12. 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

3

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.
