Director and Officer Indemnification

In addition to the indemnification provided for in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, we have entered, and we intend to continue to enter, into separate indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements may require us, among other things, to indemnify our directors and executive officers for some expenses, including attorneysŐ fees, judgments, fines and settlement amounts, incurred by a director or executive officer in any action or proceeding arising out of his service as a director, officer, employee or other agent of Volterra or any of our subsidiaries or any other company or enterprise to which the person provides services at our request.

Certain Business Relationships

Edward Ross, a member of our Board, served until December 2004 as President and Chief Executive Officer of TSMC North America, the U.S. subsidiary of Taiwan Semiconductor Manufacturing Company, Ltd., or TSMC. From January 2005 to December 2005, Dr. Ross served as President Emeritus of TSMC. TSMC is one of our principal semiconductor foundries. In 2005, we made payments to TSMC in the amount of $8.8 million. We believe that our transactions with TSMC were on terms no less favorable than could be obtained from other semiconductor foundries.
