Dear Rob:

The purpose of this letter agreement (“Agreement”) is to set forth the terms and conditions of the agreement which we have reached in connection with the voluntary resignation of your executive officer position with Microtune, Inc. (“Microtune”) and your assistance in the transitioning of your duties. Therefore, in connection with the voluntary resignation of your executive officer position at Microtune as Vice President, Chief Development Officer and Secretary, and in order to facilitate a smooth and orderly transitioning of your duties, we have agreed to provide you the benefits outlined herein.

While this document is drafted in letter form, it is intended to be a legally binding agreement which we have reached in connection with the matters outlined herein. Therefore, for and in good consideration of the mutual covenants and promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by both you and Microtune, Xxx-Xxx X. Xxxxxx and Microtune, Inc. hereby agree as follows:

1. Resignation of Executive Officer Position with Microtune. You agree to submit your voluntary resignation as an executive officer from Microtune, Inc. and you agree to resign from any officer, director and/or manager positions that you may hold with any of Microtune’s subsidiaries as of April 30, 2005.

2. Transitional Employment. As of May 1, 2005 until, May 31, 2005, you will remain employed by Microtune in order to perform the transitional tasks and duties identified on Exhibit A attached hereto (the “Identified Tasks”). In addition, you will prepare a “transition file” for the use of Microtune and its officers in the transitioning of your responsibilities. Your transitional employment will remain in effect as long as you perform the Identified Tasks in a satisfactory manner, as determined by Xxxxx Xxxxxxxx, CEO and President. You will be responsible for the Identified Tasks until May 31, 2005, and then you will continue to be employed by Microtune for “as needed” transitional and/or consulting services for a term lasting until November 15, 2005, contingent upon your satisfactory performance of any requested services, or until you accept new full time employment from another employer. In the event you obtain new full time employment prior to November 15, 2005, you will agree to resign your employment in accordance with normal resignation procedures and all benefits owing to you under this Agreement will terminate as of the date you resign. You

will not accrue any vacation days after April 30, 2005. At May 1, 2005, you will begin 84 business hours of vacation at your current rate of pay and, upon your return from vacation, you will then begin receiving cash compensation of $250.00 (less applicable federal and state withholdings) at each semi-monthly pay period until November 15, 2005 or until you accept new, full-time employment from another employer.

3. Other Agreements. You will agree to fully comply with the terms and conditions of the Invention Assignment and Confidentiality Agreement between you and Microtune dated August 25, 2003 (“Confidentiality Agreement”). In this regard, you acknowledge that you have legal obligations and responsibilities regarding your activities after the termination of your employment. By signing this Agreement, you acknowledge the existence and validity of the Confidentiality Agreement. In addition, you acknowledge that Microtune agrees to provide you with confidential information unique to Microtune during the term of your transitional employment and, by your signature, you acknowledge delivery and receipt of same. Microtune’s confidential information is defined in the Confidentiality Agreement. You and Microtune agree to fully comply with the terms and conditions of the Indemnification Agreement between you and Microtune dated August 25, 2003 (“Indemnification Agreement”). In this regard, you and Microtune acknowledge that you and Microtune have legal obligations and responsibilities under the Indemnification Agreement that continue after your resignation and after the termination of your employment. By signing this Agreement, you and Microtune acknowledge the existence and validity of the Indemnification Agreement.

4. Non-Solicitation and Non-Competition. You acknowledge and agree that information, including the confidential information, you acquire during the term of your transitional employment will enable you to irreparably injure Microtune if you should engage in unfair competition. In consideration of the compensation provided to you under this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which you acknowledge, you agree not to solicit or assist any entity in the solicitation of Microtune employees for a period beginning on the date of this Agreement and ending on November 15, 2006. For purposes of this Agreement, solicitation includes providing names and/or qualifications to an entity by which you are employed or have an ownership interest in, or any outside recruiting agency such an entity has contracted with. The term “Microtune employee” shall include former Microtune employees until such individual has been off the Microtune payroll for 90 days. Furthermore, you agree until April 30, 2006, not to engage, directly or indirectly, in any form of consultancy, employment or other advisory relationship with any company in the United States that competes directly with Microtune in the sale of Microtune’s semiconductor products and are listed in Microtune’s annual reports on Form 10-K or quarterly reports on Form 10-Q. For purposes of this Agreement, “Microtune’s semiconductor products” shall be deemed to be those products in existence on the date hereof or any products developed by Microtune

in the future in the same line of business. If you desire to accept employment or to enter into any consultancy or advisory relationship with one of these companies in a business unit or division that does not compete directly with Microtune, you will notify Microtune and provide a certification to Microtune that to the best of your knowledge, such employment or advisory relationship will not be with a business unit or division that competes directly with Microtune and you will reaffirm your confidentiality obligations under the Confidentiality Agreement as of such date. You further acknowledge and agree that these non-solicitation and non-competition restrictions including, but not limited to, the time period of restriction, the geographic areas of restriction, and the scope of the restriction, are fair and reasonable, are supported by sufficient and valid consideration, and these restrictions do not impose any greater restraint than is necessary to protect the goodwill and other legitimate business interests of Microtune. You acknowledge that these restrictions will not prevent you from obtaining gainful employment in your occupation or field of expertise or cause you undue hardship; that there are numerous other employment and business opportunities available to you that are not affected by these restrictions.

5. Announcement of Resignation. With respect to third parties, Microtune and you agree to announce that you are voluntarily resigning from your executive officer position at Microtune due to your retirement, but that you will assist Microtune with the transition of your duties.

6. Comments Regarding Microtune. You agree not to make any derogatory comments to any third party regarding Microtune, its management, or any prior or ongoing Microtune projects taking place. Microtune will also agree not to make any derogatory comments to any third party regarding your employment or the circumstances surrounding your departure. If references are requested, Microtune will provide a copy of the letter of recommendation dated April 28, 2005 from Xxxxx X. Xxxxxxxx, CEO and President promptly upon your request.

You agree that all stock option vesting after November 15, 2005 will cease and you agree not to make any claim for any other stock option or equity compensation from Microtune.

10. Enforcement. You acknowledge that the restrictions and agreements contained in this Agreement are necessary for the protection of Microtune in a highly competitive business environment and that any breach of any of the provisions of this Agreement will cause Microtune irreparable damage for which there is no adequate remedy at law, and for which Microtune could not be adequately or reasonably compensated for in monetary damages.

12. Compliance with Xxxxxxx Xxxxxxx Policy. You agree to comply with the Microtune Xxxxxxx Xxxxxxx Policy, including any blackout period, until the Form 10-Q for the quarter ended March 31, 2005 has been filed. However, if necessary, you agree to be subject to further blackout periods if Microtune determines that your transition duties have allowed you access to material, non-public information. You should consult with an attorney of your choice after that date to determine any continuing obligations you may have with respect to xxxxxxx xxxxxxx regulations.

13. No Admission of Wrongdoing. It is understood and agreed that neither this Agreement, nor any provision of the Agreement, shall be deemed to be, constitute or should be construed as, an admission of liability or wrongdoing by you or by Microtune.
