Substantially all advisory services to be rendered by CCMPA shall be rendered in Hong Kong. The Company shall furnish to each Advisor such information that each Advisor reasonably believes appropriate to provide the services to be provided by it hereunder (all such information, the “Information”). The Company acknowledges and confirms that (i) each Advisor will use and rely on the Information in performing the services to be provided by it hereunder and (ii) each Advisor does not assume responsibility for the accuracy or completeness of such Information.

3. Periodic Fees and Expenses.

(a) The Company will pay the Advisors or their respective designees a fee in the aggregate amount of $30,000,000 for services rendered in connection with the debt financing of the transactions (the “Acquisition”) contemplated by the Asset and Stock Purchase Agreement, dated as of January 8, 2006, between Texas Instruments Incorporated and S&C Purchase Corp. Such fee shall be allocated between the Advisors in accordance with each Advisor’s Fee Allocation Percentage. Each Advisor’s allocated portion of such fee will be payable to such Advisor or its designee by wire transfer of immediately available funds on the Effective Date. In addition, the Company will reimburse each Advisor or its designee, by wire transfer of immediately available funds on the Effective Date, for its reasonable travel expenses and other reasonable out-of-pocket fees and expenses (including the fees and expenses of accountants, attorneys and other advisors retained by such Advisor, subject to the terms of any existing agreement, including the Assignment and Assumption Agreement) incurred in connection with the foregoing and the investigation, negotiation, and consummation of the Acquisition.

(b) During the Term of this Agreement, the Company will pay each Advisor a quarterly advisory fee for each fiscal quarter of the Company (a “Periodic Fee”) equal to the product of (x) $1,000,000 times (y) such Advisor’s Fee Allocation Percentage on the date of payment. Each Advisor’s Periodic Fee will be payable in advance to such Advisor or its designee by wire transfer of immediately available funds on the first business day of the first month of each fiscal quarter. The pro-rated amount of each Advisor’s Periodic Fee for the period commencing on the Effective Date and ending on the last day of the Company’s fiscal quarter ending on or about June 30, 2006 will be payable by wire transfer of immediately available funds on the Effective Date.

(c) The Company will reimburse each Advisor for such reasonable travel expenses and other reasonable out-of-pocket fees and expenses (including the fees and expenses of accountants, attorneys and other advisors retained by such Advisor) as may be incurred by such Advisor and its partners, members, employees or agents in connection with the rendering of services pursuant to this Agreement. Such expenses will be reimbursed by wire transfer of immediately available funds promptly upon the request of such Advisor (but in any case no later

- 2 -

than five business days following such request) and will be in addition to any other fees or amounts payable to such Advisor pursuant to this Agreement. Unless requested by the Company, in no event shall any Advisor submit its expenses to the Company more often than monthly.

(d) The Company will deliver to (or pay on behalf of) Luxco or Dutchco, as applicable, such funds as necessary for Luxco and Dutchco to satisfy all expense reimbursement and indemnification obligations owed to its Securityholders and directors pursuant to its organizational documents or any securityholders, registration rights, investor rights, or similar agreement.

(e) The Company will pay the Advisors or their designees an aggregate fee (each, a “Subsequent Transaction Fee”) equal to 1% of the aggregate value of each transaction that is completed during the Term (or completed after any termination of this Agreement, if such transaction was contemplated at the time of termination of the Agreement) resulting in a Change in Control, acquisition, disposition or divestiture, spin-off, split-off, or financing (whether debt or equity financing) by or involving the Companies (however structured). Each Advisor shall be entitled to a portion of such Subsequent Transaction Fee equal to the product of (x) the amount of such Subsequent Transaction Fee times (y) such Advisor’s Fee Allocation Percentage at the time of the transaction.

(f) In the event of a termination of this Agreement, the Company shall pay in cash to each of the Advisors (a)(i) all unpaid Periodic Fees, (ii) all unpaid Subsequent Transaction Fees, and (iii) all expenses due under this Agreement with respect to periods prior to the termination date, plus (b) the net present value (using a discount rate equal to the yield as of such termination date on U.S. Treasury securities of like maturity) of the Periodic Fees that would have been payable with respect to the period from the termination date through the tenth anniversary of the Effective Date or, in the case of any extension thereof, through the end of such extension period.

4. Personnel. Each Advisor will provide and devote to the performance of this Agreement such partners, employees and agents of such Advisor as it shall deem appropriate to the furnishing of the services mutually agreed upon by the Company and the Advisors pursuant to Section 2 hereof; it being understood that no minimum number of hours is required to be devoted by any or all of the Advisors on a weekly, monthly, annual, or other basis. Each Advisor may, in its sole discretion, remove, substitute for, or add members to its professional employees made available by it hereunder, from time to time, on the basis of necessity, desirability or otherwise, and any such removal, substitution or addition will not in any way modify or affect any of the obligations of the Company under this Agreement, including, without limitation, its obligation to pay fees and expenses to such Advisor as provided hereunder. The fees and other compensation specified in this Agreement will be payable by the Company regardless of the extent of services requested by the Company pursuant to this Agreement, and regardless of whether or not the Company requests an Advisor to provide any such services. The Company acknowledges that the services of each of the Advisors are not exclusive, and that each of the Advisors will render similar services to other Persons (including with the same partners, employees, and agents thereof as may render services to the Company).

In no event will any of the parties hereto be liable to any other party hereto for (i) any indirect, special, incidental or consequential damages, including lost profits or savings, whether or not such damages are foreseeable, arising out of this Agreement or the performance of services hereunder, or (ii) in respect of any liabilities relating to any third party claims (whether based in contract, tort or otherwise) arising out of this Agreement or the performance of services hereunder, except as set forth in Section 6 below.

6. Indemnity.

If the indemnification provided for above is unavailable in respect of any Losses, then the Company, in lieu of indemnifying any member of the Advisor Group, shall contribute to the amount paid or payable by such member of the Advisor Group in such

Each of the Advisors and the Company agree that each Advisor shall perform services hereunder as an independent contractor, retaining control over and responsibility for its own operations and personnel.
