 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. 
  

 2 

 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.

President of Global Operations. 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) (i) by
the Company other than for Cause (as defined in Section 6.2), death or Disability (as defined in Section 6.4), or (ii) by Executive as a result of a requirement to accept a position greater than twenty-five (25) miles from
Executive’s current work location or a position of less total compensation (i.e. base salary plus bonus target), and provided any of the events identified in the preceding clauses (i) and (ii) occurs within 12 months following
a Change of Control (as defined in Section 6.3 of this Agreement) or within three 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 on the date that is six months and one day following 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 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. 
 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 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 an amount that would not
cause any portion of those payments and benefits to constitute “parachute payments.” 
 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. If cash severance pay is payable to Executive under this Agreement, cash severance pay shall not be payable to Executive
under any other agreement with the Company in effect at the time of termination (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). 
 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 as a result of a requirement by the Company (including any subsidiary of the Company) that he accept a position requiring a relocation of
greater than twenty-five (25) miles from his current work location or a position of less total compensation (i.e. base salary plus bonus target). A Termination of Executive’s Employment is intended to mean a termination of
employment which constitutes a “separation from service” under Code Section 409A. 
  

 2 

 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 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. 
 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.

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, and
that there exist no other agreements between the parties, oral or written, express or implied, relating to any matters covered by this Agreement. 
 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 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.

may be modified unless such modification is agreed to in writing signed by Executive and the Company.

term had never been contained in this Agreement.

Notwithstanding any provision of the Agreement to the contrary, the 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 the Agreement so that it will comply with the requirements of Code Section 409A, the Company does not represent or warrant that the 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 the 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. 
 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. If any such payment or
reimbursement 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 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 14 shall be paid to Executive in a
lump sum, and any remaining payments due under this Section 14 shall be payable in accordance with their original payment schedule. 
 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.
