Re:     Change in Control / Severance Agreement

Dear Dave:

This letter sets out the severance arrangements concerning your employment with Skyworks Solutions, Inc. (“Skyworks”).

1. Change of Control

     (a) the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (a “Person”) of beneficial ownership of any capital stock of the Company if, after such acquisition, such Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the Exchange Act) 40% or more of either (x) the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the then-outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (a), the following acquisitions shall not constitute a Change of Control: (i) any acquisition directly from the Company (excluding an acquisition pursuant to the exercise, conversion or exchange of any security exercisable for, convertible into or exchangeable for common stock or voting securities of the Company, unless the Person exercising, converting or exchanging such security

acquired such security directly from the Company or an underwriter or agent of the Company), (ii) any acquisition by the Company, (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, or (iv) any acquisition by any corporation pursuant to a transaction which complies with clauses (i) and (ii) of subsection (c) of this Section 1.2; or

     (b) such time as the Continuing Directors (as defined below) do not constitute a majority of the Board (or, if applicable, the Board of Directors of a successor corporation to the Company), where the term “Continuing Director” means at any date a member of the Board (i) who was a member of the Board on the date of the execution of this Agreement or (ii) who was nominated or elected subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or endorsed by at least a majority of the directors who were Continuing Directors at the time of such nomination or election; provided, however, that there shall be excluded from this clause (ii) any individual whose initial assumption of office occurred as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents, by or on behalf of a person other than the Board; or

     (c) the consummation of a merger, consolidation, reorganization, recapitalization or statutory share exchange involving the Company or a sale or other disposition of all or substantially all of the assets of the Company in one or a series of transactions (a “Business Combination”), unless, immediately following such Business Combination, each of the following two conditions is satisfied: (i) all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors, respectively, of the resulting or acquiring corporation in such Business Combination (which shall include, without limitation, a corporation which as a result of such transaction owns the Company or substantially all of the Company’s assets either directly or through one or more subsidiaries) (such resulting or acquiring corporation is referred to herein as the “Acquiring Corporation”) in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the Outstanding Company Common Stock and Outstanding Company Voting Securities, respectively; and (ii) no Person (excluding any employee benefit plan (or related trust) maintained or sponsored by the Company or by the Acquiring Corporation) beneficially owns, directly or indirectly, 40% or more of the then outstanding shares of common stock of the Acquiring Corporation, or of the combined voting power of the then-outstanding securities of such corporation entitled

2. Termination Without Cause or for Good Reason

3. Non-Competition

During the term of your employment with Skyworks and for the first twenty-four (24) months after the date on which your employment with Skyworks is voluntarily or involuntarily terminated (the “Noncompete Period”), you will not engage in any employment, consulting or other activity that competes with the business of Skyworks or any subsidiary or affiliate of Skyworks (collectively, the “Company”). You acknowledge and agree that your direct or indirect participation in the conduct of a competing business alone or with any other person will materially impair the business and prospects of Skyworks. During the Noncompete Period, you will not (i) attempt to hire any director, officer, employee or agent of Skyworks, (ii) assist in such hiring by any other person, (iii) encourage any person to terminate his or her employment or business relationship with Skyworks, (iv) encourage any customer or supplier of Skyworks to terminate its relationship with Skyworks, or (v) obtain, or assist in obtaining, for your own benefit (other than indirectly as an employee of the Company) any customer of Skyworks. If any of the restrictions in this Section 3 are adjudicated to be excessively broad as to scope,

geographic area, time or otherwise, said restriction shall be reduced to the extent necessary to make the restriction reasonable and shall be binding on you as so reduced. Any provisions of this section not so reduced will remain in full force and effect.

It is understood that during the Noncompete Period, you will make yourself available to the Company for consultation on behalf of the Company, upon reasonable request and at a reasonable rate of compensation and at reasonable times and places in light of any commitment you may have to a new employer.

You understand and acknowledge that the Company’s remedies at law for breach of any of the restrictions in this Section are inadequate and that any such breach will cause irreparable harm to Skyworks. You therefore agree that in addition and as a supplement to such other rights and remedies as may exist in Skyworks’ favor, Skyworks may apply to any court having jurisdiction to enforce the specific performance of the restrictions in this Section, and may apply for injunctive relief against any act which would violate those restrictions.

4. Death or Disability

In the event of your death at any time during your employment by Skyworks, all of your then outstanding Company stock options, whether or not by their terms then exercisable, will become immediately exercisable and remain exercisable for a period of one year thereafter, subject to their other terms and conditions.

In the event of your disability at any time during your employment by Skyworks, all of your then outstanding Company stock options, whether or not by their terms then exercisable, will become immediately exercisable and remain exercisable so long as you remain an employee or officer of Skyworks and for a period of one year thereafter, subject to their other terms and conditions.

5. Miscellaneous

All claims by you for benefits under this Agreement shall be directed to and determined by the Board of Directors of the Company and shall be in writing. Any denial by the Board of Directors of a claim for benefits under this Agreement shall be delivered to you in writing and shall set forth the specific reasons for the denial and the specific provisions of this Agreement relied upon. The Board of Directors shall afford a reasonable opportunity to you for a review of the decision denying a claim. Any further dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Boston, Massachusetts, in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. The Company agrees to pay as incurred, to the full extent permitted by law, all legal, accounting and other fees and expenses which you may reasonably incur as a result of any claim or contest (regardless of the outcome thereof) by the Company, you or others regarding the validity or enforceability of, or

liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by you regarding the amount of any payment or benefits pursuant to this Agreement), plus in each case interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code.

Notwithstanding anything in this letter to the contrary, no provision of this letter will operate to extend the term of any option beyond the term originally stated in the applicable option grant or option agreement.

Neither you nor the Company shall have the right to accelerate or to defer the delivery of the payments to be made under Section 1.3 or 2.4; provided, however, that if you are a “specified employee” as defined in Section 409A(a)(2)(B)(i) of the Internal Revenue Code of 1986, as amended (the “Code”) and any of the payments to be made to you hereunder constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code, then the commencement of the delivery of any such payments will be delayed to the date that is 6 months after your date of termination.

This agreement contains the entire understanding of the parties concerning its subject matter. This agreement may be modified only by a written instrument executed by both parties. This agreement replaces and supersedes all prior agreements relating to your employment or severance, including without limitation the letter agreement between you and Alpha Industries, Inc. dated April 1, 2001. This agreement will be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts.

Please sign both copies of this letter and return one to Skyworks.
