1. Position; Term.

(a) You will continue to be employed by Intersil as its President and Chief Operating Officer until January 24 , 2008, unless sooner terminated in accordance with Section 6 hereof (the “Initial Term”). The Initial Term will be automatically extended for successive one year periods beginning January 25, 2008 unless either party gives three (3) months prior written notice of non-renewal to the other party, or unless your employment is otherwise terminated (the Initial Term and any such extensions being your “Term of Employment”).

Your principal location of employment will be at Intersil’s offices in Milpitas, California.

2. Base Salary. During the Term of Employment, your initial base salary will be $375,000 per year, payable in accordance with Intersil’s normal payroll practices with such payroll deductions and withholdings as are required by law. During your Term of Employment, your base salary will be reviewed on an annual basis beginning in April 2007 and may be increased from time to time, in the sole discretion of the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”), but in no event shall your base salary be reduced below the initial salary amount set forth herein. Your base salary as adjusted shall be referred to herein as your “Base Salary.”

3. Bonus.

Your target annual bonus will be reviewed on an annual basis beginning in April 2007 and may be adjusted from time to time, in the sole discretion of the Compensation Committee

4. Equity Compensation.

(a) Stock Options. Pursuant to a separate award agreement, and subject to the terms of Intersil’s 1999 Equity Compensation Plan, as amended and restated May 1, 2005 (the “Stock Plan”) except as specifically provided hereunder, the Compensation Committee of the Board shall grant you on April 3, 2006 (the “Initial Grant Date”) an option to purchase 37,500 shares of the Class A Common Stock of Intersil (“Common Stock”) at an exercise price equal to the closing price of the Common Stock as quoted on the NASDAQ on the Initial Grant Date and you will be granted options to purchase 37,500 shares of Common Stock on the first business day following July 1, 2006, October 1, 2006 and January 1, 2007, at an exercise price equal to the closing price on the applicable grant date (collectively, the options granted hereunder are referred to as the “New Options”). The New Options shall vest over a four-year period as follows: one-fourth of all of the New Options (regardless of the date granted) will vest on the first anniversary of the Initial Grant Date; the remaining portion of the New Options shall vest in equal quarterly installments over the next twelve calendar quarters. Provided you are

employed by the Company on the relevant grant date, in calendar year 2007, if you meet specific goals established by the CEO, you will be granted options to purchase additional shares of Intersil Class A Common Stock that will be issued in an amount determined by the CEO and Compensation Committee and granted and priced quarterly. Such additional options will vest 25% per year beginning on the first anniversary of the grant date and will be fully vested at the end of four years.

(b) Performance Shares. Pursuant to a separate award, and subject to the terms of the Stock Plan and the applicable award agreement thereunder, you will be granted 60,000 performance-based deferred stock units (“DSUs”) (the “Performance Shares”) on January 25, 2006 (the “Grant Date”), with the number of Performance Shares ultimately earned being subject to upward adjustment (up to 200% of the total number of Performance Shares initially granted) or downward adjustment (down to no Performance Shares) in view of Intersil’s financial performance relative to its peer group (as determined by the Compensation Committee) over a three-year performance period ending December 31, 2008. Intersil’s financial performance relative to its peer group will be determined by the Compensation Committee based upon Intersil’s revenue growth and Intersil’s growth in operating income relative to its peer group. The number of Performance Shares ultimately earned shall be determined by the Compensation Committee at the end of the three-year performance period, and the award, if any, shall become vested at such time. No payment of Performance Shares will be made to you in the event of a Voluntary Termination or Termination for Cause before the end of the three-year performance period. Provided that your employment has not terminated, you will be eligible to receive another grant of performance-based DSUs in 2007.

5. Other Benefits. You will be eligible for the normal vacation, health insurance, 401(k), employee stock purchase plan, financial planning, executive physical and other benefits offered to all Intersil senior executives of similar rank and status.

In no event shall the expiration of the Term of Employment (giving effect to any extensions thereof), by virtue of either party’s having given notice of non-renewal pursuant to Section 1(a) hereof, constitute Termination without Cause, an Involuntary Termination or Termination for Death or Disability.

7. Separation Benefits. Upon termination of your employment with Intersil for any reason during the Term of Employment, you will receive payment for all unpaid salary and vacation accrued to the date of your termination of employment; and your benefits will be continued under Intersil’s then existing benefit plans and policies for so long as provided under the terms of such plans and policies and as required by applicable law. Subject to your compliance with Sections 10 and 11, under certain circumstances, you will also be entitled to receive severance benefits as set forth below, but you will not be entitled to any other compensation, award or damages with respect to your employment or termination (except to the extent you are entitled to benefits under your Executive Change in Control Severance Benefits Agreement with Intersil (the “Severance Benefits Agreement”), in lieu of any benefits provided below, in the event of a Covered Termination (as defined in the Severance Benefits Agreement)).

You will be eligible to continue, at Intersil’s expense, your life insurance benefits providing for coverage or payment in the event of your (or your covered dependents’) death that were provided to you, whether taxable or non-taxable and whether funded through insurance or otherwise under any benefits plan or program maintained by Intersil on the same terms and conditions as in effect immediately prior to your

termination until the earlier of (i) the date on which your Employment Term ends and (ii) the one year anniversary of your termination date. With respect to any of such benefits for which you will be eligible to continue that are provided through an insurance policy, Intersil’s obligation to provide such benefits following your termination shall be limited by the terms of such policy.

Solely for purposes of this Section 7(c), “Termination without Cause” shall mean Intersil’s termination of your employment for any reason other than fraud, misappropriation or embezzlement by you which results in material loss, damage or injury to Intersil as determined by the CEO and legal counsel that you were guilty of such conduct and specifying the particulars thereof in detail. In the event that the CEO and legal counsel so determine that your termination is not a Termination without Cause under this Section 7(c), then you will be treated as being terminated for Cause and subject to Section 7(a).

(f) If any payments due under this Section 7 or otherwise would subject you to any penalty tax imposed under Section 409A of the Code if such payments were made as required above, then the payments that cause the imposition of such penalty tax shall be payable in one lump sum on the first day which is at least six months after the date of your separation of service as set forth in Section 409A of the Code and the regulations and other official guidance thereunder.

Exhibit A

Intersil Corporation

Employee Agreement and Release

I understand and agree completely to the terms set forth in the foregoing agreement.

I hereby confirm my obligations under all agreements regarding proprietary information and inventions which I executed in favor of Xicor, Inc. and Intersil Corporation shall inure to the benefit of the Company and be fully enforceable by, and apply in all respects with respect to, the Company.

I acknowledge that I have read and understand Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected this settlement with the debtor.” I hereby expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to my release of any claims I may have against the Company.

Except as otherwise set forth in this Agreement, I hereby release, acquit and forever discharge the Company, its parents and subsidiaries, and their officers, directors, agents, servants, employees, shareholders, successors, assigns and affiliates, of and from any and all claims, liabilities, demands, causes of action, costs, expenses, attorneys fees, damages, indemnities and obligations of every kind and nature, in law, equity, or otherwise, known and unknown, suspected and unsuspected, disclosed and undisclosed (other than any claim for indemnification I may have as a result of any third party action against me based on my employment with the Company), arising out of or in any way related to agreements, events, acts or conduct at any time prior to and including the Effective Date of this Agreement, including but not limited to: all such claims and demands directly or indirectly arising out of or in any way connected with my employment with the Company or the termination of that employment, including but not limited to, claims of intentional and negligent infliction of emotional distress, any and all tort claims for personal injury, claims or demands related to salary, bonuses, commissions, stock, stock options, or any other ownership interests in the Company, vacation pay, fringe benefits, expense reimbursements, severance pay, or any other form of compensation; claims pursuant to any federal, state or local law or cause of action including, but not limited to, the federal Civil Rights Act of 1964, as amended; the federal Age Discrimination in Employment Act of 1967, as amended (“ADEA”); the federal American with Disabilities Act of 1990; the California Fair Employment and Housing Act, as amended; tort law; contract law; wrongful discharge; discrimination; fraud; defamation; emotional distress; and breach of the implied covenant of good faith and fair dealing; provided, however, that nothing in this paragraph shall be construed in any way to release the Company from its obligation to indemnify you pursuant to the Company’s Indemnification Agreement and to provide you with continued coverage under the Company’s directors and officers liability insurance policy to the same extent that it has provided such coverage to previously departed officers and directors of the Company.

I acknowledge that I am knowingly and voluntarily waiving and releasing any rights I may have under ADEA. I also acknowledge that the consideration given for the waiver and release in the preceding paragraph hereof is in addition to anything of value which I was already entitled. I further acknowledge that I have been advised by this writing, as required by the ADEA, that: (a) my waiver and release do not apply to any rights or claims that may arise after the Effective Date of this Agreement; (b) I have the right to consult with an attorney prior to executing this Agreement; (c) I have twenty-one (21) days to consider this Agreement (although I may choose to voluntarily execute this Agreement earlier); (d) I have seven (7) days following the execution of this Agreement by the parties to revoke the Agreement; and (e) this Agreement shall not be effective until the date upon which the revocation period has expired, which shall be the eighth day after this Agreement is executed by me, provided that the Company has also executed this Agreement by that date.
