The Company is not proposing to increase the number of shares authorized for issuance under such plan.

You are cordially invited to attend the meeting in person. Whether or not you expect to attend the meeting, please complete, date, sign and return the enclosed proxy as promptly as possible in order to ensure your representation at the meeting. A return envelope (which is postage prepaid if mailed in the United States) is enclosed for your convenience. Even if you have voted by proxy, you may still vote in person if you attend the meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must obtain a proxy issued in your name from that record holder.

PROXY STATEMENT
FOR THE 2007 ANNUAL MEETING OF STOCKHOLDERS
 
May 30, 2007
 
QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING
 
 
We sent you this proxy statement and the enclosed proxy card because the Board of Directors of Volterra Semiconductor Corporation (sometimes referred to as the “Company” or “Volterra”) is soliciting your proxy to vote at the 2007 Annual Meeting of Stockholders. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card.
 
Volterra intends to mail this proxy statement and accompanying proxy card on or about April 24, 2007 to all stockholders of record entitled to vote at the annual meeting.
 
 
Only stockholders of record at the close of business on April 2, 2007 will be entitled to vote at the annual meeting. On this record date, there were 24,488,744 shares of common stock outstanding and entitled to vote.
 
 
If on April 2, 2007 your shares were registered directly in your name with Volterra’s transfer agent, Registrar and Transfer Company, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.
 
 
If on April 2, 2007 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.
 
 
There are three matters scheduled for a vote:
 
  •  Election of three directors;
 
  •  Approval of certain changes to our 2004 Non-Employee Directors’ Stock Option Plan, as described herein; and
 
  •  Ratification of KPMG LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2007.

Table of Contents

 
 
For Proposal No. 1, you may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For Proposal No. 2, the approval of an amendment to our 2004 Non-Employee Directors’ Stock Option Plan, you may vote “For” or “Against” or abstain from voting. For Proposal No. 3, the ratification of the selection by the Audit Committee of KPMG LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2007, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:
 
 
If you are a stockholder of record, you may vote in person at the annual meeting or vote by proxy using the enclosed proxy card. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person if you have already voted by proxy.
 
  •  To vote in person, come to the annual meeting and we will give you a ballot when you arrive.
 
  •  To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.
 
 
If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from Volterra. Simply complete and mail the proxy card to ensure that your vote is counted. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.
 
 
On each matter to be voted upon, you have one vote for each share of common stock you own as of April 2, 2007.
 
 
If you return a signed and dated proxy card without marking any voting selections, your shares will be voted “For” the election of both nominees for director, “For” the amendment of our 2004 Non-Employee Directors’ Stock Option Plan, as described herein, and “For” the ratification of the selection by the Audit Committee of the Board of Directors of KPMG LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2007. If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.
 
 
We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.
 
 
If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:
 
  •  You may submit another properly completed proxy card with a later date.
 
  •  You may send a written notice that you are revoking your proxy to Volterra’s Secretary at 3839 Spinnaker Court, Fremont, CA 94538.
 
  •  You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.
 
If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.
 
 
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 26, 2007, to Volterra’s Secretary at 3839 Spinnaker Court, Fremont, CA 94538. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director, you must do so not later than the close of business on March 31, 2008 nor earlier than the close of business on March 1, 2008. You are also advised to review Volterra’s Bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.
 
 
Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and “Withhold” and, with respect to proposals other than the election of directors, “Against” votes, abstentions and broker non-votes. Abstentions will be counted towards the vote total for each proposal, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal. A broker non-vote occurs when a nominee, such as a broker or bank, holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that proposal and has not received instructions with respect to that proposal from the beneficial owner (despite voting on at least one other proposal for which it does have discretionary authority or for which it has received instructions). In the event that a broker, bank, custodian, nominee or other record holder of Volterra’s common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-votes with respect to that proposal.
 
 
  •  For Proposal No. 1, the election of directors, the three nominees receiving the most “For” votes (among votes properly cast in person or by proxy) will be elected. Only votes “For” or “Withheld” will affect the outcome.
 
  •  To be approved, Proposal No. 2, the approval of an amendment and restatement of the 2004 Non-Employee Directors’ Stock Option Plan, as described herein, must receive a “For” vote from the majority of shares voting either in person or by proxy. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.
 
  •  To be approved, Proposal No. 3, the ratification of the selection by the Audit Committee of the Board of Directors of KPMG LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2007, must receive a “For” vote from the majority of shares present and entitled to vote either in person or by proxy. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares entitled to vote are represented by stockholders present at the meeting or by proxy. On the record date (April 2, 2007), there were 24,488,744 shares outstanding and entitled to vote. Thus, assuming all such shares remain outstanding on the date of the annual meeting, 12,244,373 shares must be represented by stockholders present at the meeting or by proxy to have a quorum.
 
Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, a majority of the votes present at the meeting may adjourn the meeting to another date.
 
 
Preliminary voting results will be announced at the annual meeting. Final voting results will be published in the Company’s quarterly report on Form 10-Q for the second quarter of 2007.
 
Proposal 1
 
 
Volterra’s Board of Directors (the “Board”) is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class shall serve for the remainder of the full term of that class, and until the director’s successor is elected and qualified. This includes vacancies created by an increase in the number of directors.
 
The Board presently has seven members. There are three directors in the class whose term of office expires in 2007: Alan King, Jeffrey Staszak and Edward Winn.
 
Each of the three nominees listed below is currently a director of the Company who was recommended for election to the Board by the Nominating and Corporate Governance Committee of the Board. Proxies may not be voted for a greater number of persons than the number of nominees named. Mr. King was previously elected as a director by the Board in 1996, Mr. Staszak was previously elected as a director by the Board in 2000 and Mr. Winn was previously elected as a director by the Board in 2004. If elected at the annual meeting, each of these nominees would serve until the 2010 annual meeting and until his successor is elected and has qualified, or until the director’s death, resignation or removal. It is the Company’s policy to encourage directors and nominees for director to attend the annual meeting. In 2006, the following directors attended the annual meeting of stockholders: Alan King, Mel Friedman, Christopher Paisley, Jeffrey Staszak, Anthony Stratakos and Edward Winn.
 
The following is a brief biography of each nominee and each director whose term will continue after the annual meeting.
 
 
 
Mr. Alan King, age 71, has been our Chairman of the Board since October 1997 and a member of our Board since November 1996.

As required under the Nasdaq stock market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. The board consults with the company’s counsel to ensure that the board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect time to time.
 
Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board has determined that all of the Company’s directors are independent directors within the meaning of the applicable Nasdaq listing standards, except for Mr. Staszak, the President and Chief Executive Officer of the Company and Dr. Stratakos, the Company’s Vice President of Advanced Research and Development and Chief Technology Officer.
 
 
The Board has established corporate governance guidelines to ensure that the Board will have the necessary authority and practices in place to review and evaluate the Company’s business operations as needed and, where appropriate, to make decisions that are independent of the Company’s management. The guidelines are also intended to align the interests of directors and management with those of the Company’s stockholders. The corporate governance guidelines set forth the practices the Board will follow with respect to: Board organization and independence of directors; committee composition; board meetings; communication with management, employees stockholders, journalists, analysts and other outside parties; retention of advisors; election and service of directors; and continuing director education. The corporate governance guidelines were adopted by the Board to, among other things, reflect changes to the Nasdaq listing standards and Securities and Exchange Commission rules adopted to implement provisions of the Sarbanes-Oxley Act of 2002.
 
Persons interested in communicating with the independent directors with their concerns or issues may address correspondence to a particular director, or to the independent directors generally, in care of the Chief Financial Officer of Volterra Semiconductor Corporation at 3839 Spinnaker Court, Fremont, CA 94538. If no particular director is named, letters will be forwarded, depending on the subject matter, to the Chairperson of the Audit, Compensation, or Nominating and Corporate Governance Committee.

Below is a description of each committee of the Board. Each of the Audit and Compensation Committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable rules and regulations regarding “independence” and that each member is free of any relationship that would interfere with his individual exercise of independent judgment with regard to the Company.
 
 
The Audit Committee of the Board oversees the Company’s corporate accounting and financial reporting process. For this purpose, the Audit Committee performs several functions, including:
 
  •  evaluating the performance of our independent auditor, assessing their qualifications and independence, and determining and approving their engagements;
 
  •  reviewing our annual financial statements, discussing with management and our independent auditor the results of our annual audit, and discussing with management and our auditor the results of the auditors’ review of our quarterly financial statements;
 
  •  reviewing with management and our auditor significant issues that arise regarding accounting principles and financial statement presentation;
 
  •  reviewing and discussing with management and our independent auditor, as appropriate, our guidelines and policies with respect to risk assessment and risk management;
 
  •  reviewing with our independent auditor any significant difficulties with our annual audit or any restrictions on the scope of their activities or access to required records, data and information, significant disagreements with management and management’s response, if any;
 
  •  reviewing with our independent auditor and management any conflicts or disagreements between management and our independent auditor regarding financial reporting or accounting practices or policies and resolving any such conflicts regarding financial reporting;
 
  •  conferring with our independent auditor and management regarding the scope, adequacy and effectiveness of our internal financial reporting controls; and
 
  •  reviewing and approving related-party transactions and reviewing other issues arising under our Code of Conduct or similar policies.
 
Three directors currently comprise the Audit Committee: Messrs. Paisley, Friedman and Winn. Mr. Paisley serves as chairperson. The Audit Committee met eleven times during 2006. The Board has adopted a written Audit

The Board has reviewed the Nasdaq listing standards definition of independence for Audit Committee members and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 4350(d)(2)(A)(i) and (ii) of the Nasdaq listing standards). The Board has determined that Mr. Paisley qualifies as an “audit committee financial expert,” as defined in applicable Securities and Exchange Commission (“SEC”) rules. The Board made a qualitative assessment of Mr. Paisley’s level of knowledge and experience based on a number of factors, including his formal education and experience as the chief financial officer of a public company.
 
 
The Compensation Committee of the Board reviews and approves the overall compensation strategy and policies for the Company. For this purpose, the Compensation Committee performs several functions, including:
 
  •  reviewing and approving the compensation of our chief executive officer;
 
  •  reviewing and approving the compensation policies, plans and programs for our executive officers and other senior management, as well as our overall compensation plans and structure;
 
  •  recommending to our Board the compensation for our independent directors; and
 
  •  administering our stock plans and employee benefit plans.
 
The Company also has a Non-Officer Stock Option Committee, which is a sub-committee of the Compensation Committee and is composed of the Company’s Chief Executive Officer, Jeffrey Staszak and the Company’s Vice-President of Finance and Chief Financial Officer, Greg Hildebrand. The Non-Officer Stock Option Committee may award stock options to new employees, excluding employees who are executive officers, subject to certain guidelines approved by the Board. The Company’s policy is that all grants made by the Non-Officer Stock Option Committee are to be reviewed and ratified by the Compensation Committee at its next scheduled meetings.
 
Three directors currently comprise the Compensation Committee: Messrs. Paisley and Winn and Dr. Ross. Dr. Ross serves as chairperson. All members of the Company’s Compensation Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards). The Compensation Committee met five times and acted by unanimous written consent one time during 2006. The Compensation Committee charter can be found at the Governance — Committee Composition section of our corporate website at http://investors.volterra.com.
 
 
The Nominating and Corporate Governance Committee of the Board is responsible for:
 
  •  establishing criteria for board membership and reviewing and recommending nominees for election as directors;
 
  •  considering board nominations and proposals submitted by our stockholders;
 
  •  assessing the performance of our Board and the independence of directors;
 
  •  recommending to the Board the chairmanship and membership of each Board committee; and
 
  •  developing our corporate governance principles.
 
The Nominating and Corporate Governance Committee charter can be found at the Governance — Committee Composition section of our corporate website at http://investors.volterra.com. Three directors comprise the Nominating and Corporate Governance Committee: Messrs. King, Friedman and Ross. Mr. King serves as chairperson. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee met six times during 2006.

The Nominating and Corporate Governance Committee has not established any stated specific, minimum qualifications that must be met by a candidate for a position on our Board. The Nominating and Corporate Governance Committee will consider all of the relevant qualifications of Board candidates, including such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of Volterra, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, having the commitment to rigorously represent the long-term interests of our stockholders, and whether the Board candidates will be independent for Nasdaq purposes, as well as the needs of the Board and Volterra. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee will also review such directors’ overall service to Volterra during their terms, and any relationships and transactions that might impair such directors’ independence. The Nominating and Corporate Governance Committee will conduct any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. At this time, the Nominating and Corporate Governance Committee does not believe that the establishment of stated specific, minimum qualifications that must be met by a candidate for a position on our Board is necessary or appropriate. To date, the Nominating and Corporate Governance Committee has not paid a fee to any third party to assist in the process of identifying or evaluating director candidates.
 
The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at the 2008 Annual Meeting may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 3839 Spinnaker Court, Fremont, CA 94538 at least 120 days prior to the anniversary date of the mailing of this proxy statement. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record owner of our common stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.
 
 
The Board met five times and acted by unanimous written consent two times during 2006. All directors attended at least 75% of the aggregate of the meetings of the Board and of the committees on which they served, held during the period for which they were a director or committee member, respectively.
 
 
The Company has not adopted a formal process for stockholder communications with the Board. Nevertheless, every effort has been made to ensure that the views of stockholders are heard by the Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. We believe our responsiveness to stockholder communications to the Board has been excellent. Nevertheless, the Nominating and Corporate Governance Committee will consider, from time to time, whether adoption of a formal process for stockholder communications with the Board has become necessary or appropriate.
 
 
The Company has adopted a Code of Conduct that applies to all of Volterra’s officers, directors and employees. The Code of Conduct is available at the Governance section of the Company’s website at http://investors.volterra.com. If the Company makes any substantive amendments to the Code of Conduct or grants any waiver from a provision of the Code of Conduct to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website, or as otherwise required by applicable law, rules or regulations.

The Audit Committee of the Board currently consists of three members: Messrs. Paisley, Friedman and Winn. Mr. Paisley serves as Chairperson of the Audit Committee. All members of Volterra’s Audit Committee are independent (as independence is defined in Rules 4200(a)(15) and 4350(d) of the Nasdaq listing standards).
 
The Audit Committee oversees Volterra’s corporate accounting and financial reporting process on behalf of the Board. Management has primary responsibility for the financial statements and the reporting process, including the systems of internal controls and disclosure controls and procedures. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in Volterra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006 with management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.
 
The Audit Committee is responsible for reviewing, approving and managing the engagement of the Company’s independent registered public accounting firm, including the scope, extent and procedures of the annual audit and compensation to be paid thereto, and all other matters the Audit Committee deems appropriate, including the independent registered public accounting firm’s accountability to the Board and the Audit Committee. The Audit Committee reviewed with the independent registered public accounting firm, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of Volterra’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards and those matters required to be discussed by the Statement on Auditing Standards No. 61. In addition, the Audit Committee has discussed with the independent registered public accounting firm the auditors’ independence from management and Volterra, including the matters in the written disclosures required by the Independence Standards Board Standard No. 1, and has considered the compatibility of non-audit services with the auditors’ independence.
 
The Audit Committee discussed with Volterra’s independent registered public accounting firm the overall scope and plans for their audits. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, their evaluation of Volterra’s internal controls and the overall quality of Volterra’s financial reporting. The Audit Committee held eleven meetings during the fiscal year ended December 31, 2006.
 
In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board has approved, that the audited financial statements be included in Volterra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006 for filing with the Securities and Exchange Commission. The Audit Committee has also retained, subject to stockholder ratification described in Proposal 3, KPMG LLP as Volterra’s independent registered public accounting firm for the fiscal year ending December 31, 2007.

Proposal 2
 
 
On May 17, 2004, the Board adopted, and the stockholders subsequently approved, Volterra’s 2004 Non-Employee Directors’ Stock Option Plan (the “Directors’ Plan”). Pursuant to the terms of the Directors’ Plan, as of February 28, 2007 there were 187,500 shares of common stock reserved for issuance under the Directors’ Plan. Under Directors’ Plan, the number of shares reserved for issuance will be increased annually on December 31 of each year, from 2005 and until 2013, by no more than the number of shares of common stock subject to options granted during that calendar year. The Board may act, prior to the last day of the fiscal year, to increase the share reserve by such number as the Board shall determine, which number shall be less than the amount described above.
 
As of February 28, 2007 options (net of canceled or expired options) covering an aggregate of 62,500 shares of our common stock had been granted under the Directors’ Plan, and 125,000 shares of common stock (plus any shares that might in the future be returned to the Directors’ Plan as a result of cancellations or expiration of options) remained available for future grant under the Directors’ Plan as of such date.
 
Stockholders are requested in this Proposal 2 to approve an amendment to the Directors’ Plan, which would increase the number of shares issuable pursuant to initial grants under the Directors’ Plan from 15,600 shares to 30,000 shares, and would increase the number of shares issuable pursuant to annual grants under the Directors’ Plan from 5,625 shares per year to 10,000 shares per year. The Company is not proposing to increase the number of shares authorized for issuance under such plan. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting will be required to approve the Directors’ Plan, as amended. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.
 
The Board of Directors Recommends
 
The essential features of the Directors’ Plan, as amended, are outlined below. This summary, however, does not purport to be a complete description of the Directors’ Plan. The Directors’ Plan is attached to this proxy statement as Appendix A. The following summary is qualified in its entirety by reference to the complete text of the Directors’ Plan.
 
 
The Directors’ Plan provides for the automatic grant of nonstatutory stock options in accordance with a prescribed formula. Options granted under the Directors’ Plan are not intended to qualify as “incentive stock options” within the meaning of Section 422 of the Code. See “Federal Income Tax Information” for a discussion of the tax treatment of nonstatutory stock options.
 
 
The Board adopted the Directors’ Plan to provide a means by which non-employee directors of Volterra may be given an opportunity to purchase our stock, to assist in retaining the services of such persons, to secure and retain the services of persons capable of filling such positions and to provide incentives for such persons to exert maximum efforts for the success of Volterra. Five of the current directors of Volterra are non-employee directors and are eligible to participate in the Directors’ Plan.
 
 
The Board administers the Directors’ Plan. The Board has the power to construe and interpret the Directors’ Plan but not to determine the persons to whom or the dates on which options will be granted, the number of shares to be subject to each option, the time or times during the term of each option within which all or a portion of such option may be exercised, the exercise price, the type of consideration or the other terms of the option except to the extent not specified in the Directors’ Plan.

An aggregate of 187,500 shares of common stock is reserved for issuance under the Directors’ Plan. If options granted under the Directors’ Plan expire or otherwise terminate without being exercised, the shares of common stock not acquired pursuant to such options again come available for issuance under the Directors’ Plan. The number of shares reserved for issuance will be increased annually on December 31 of each year, from 2005 and until 2013, by no more than the number of shares of common stock subject to options granted during that calendar year. The Board may act, prior to the last day of the fiscal year, to increase the share reserve by such number as the Board shall determine, which number shall be less than the amount described above.
 
 
The Directors’ Plan provides that options may be granted only to non-employee directors of Volterra. A “non-employee director” is defined in the Directors’ Plan as a director of Volterra who is not otherwise an employee of Volterra or any affiliate.
 
 
The following is a description of the terms of options under the Directors’ Plan:
 
Automatic Grants.  Under the Directors’ Plan, each person who is appointed or elected for the first time to be a non-employee director of Volterra is automatically granted, subject to approval of this Proposal 2, a one-time initial grant to purchase 30,000 shares of Volterra’s common stock. Additionally, on the date of each annual meeting of stockholders, each non-employee director of Volterra is automatically granted an “annual grant” to purchase 10,000 shares of Volterra’s common stock; provided that if the person has not been serving as a non-employee director for the entire period since the preceding annual meeting, then the number of shares subject to such annual grant shall be reduced pro rata for each full quarter prior to the date of grant during which such person did not serve as a non-employee director.
 
Exercise Price; Payment.  The exercise price of options shall be 100% of the fair market value of the stock subject to the option on the date of grant. Under the Directors’ Plan, the fair market value of our common stock is equal to the closing sales price as reported on the Nasdaq Global Market on the last trading day prior to the date of grant. As of February 28, 2007, the closing price of our common stock as reported on the Nasdaq Global Market was $14.08 per share.
 
The exercise price of options granted under the Directors’ Plan may be paid in any combination of (i) cash or check, (ii) delivery of other Volterra common stock or (iii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the exercised common stock, results in either the receipt of cash (or check) by Volterra or the receipt of irrevocable instructions to pay the aggregate exercise price to Volterra from the sales proceeds.
 
Option Exercise.  Options granted under the Directors’ Plan pursuant to initial grants will become exercisable in cumulative increments, with 1/3rd of the shares vesting each year over three successive years. Options granted pursuant to annual grants will vest and become exercisable in full on the day prior to the date of the first annual meeting following the date on which the grant was made. An optionholder may satisfy any federal, state or local tax withholding obligation relating to the exercise of such option (in addition to our right to withhold from any compensation paid to the optionholder by us) by a cash payment upon exercise, by authorizing us to withhold a portion of the stock otherwise issuable to the optionholder, by delivering already-owned common stock of Volterra or by a combination of these means.
 
Term.  The term of options under the Directors’ Plan is seven years. Options under the Directors’ Plan terminate three months after termination of the optionholder’s service unless (i) such termination is due to the optionholder’s disability, in which case the option may be exercised (to the extent the option was exercisable at the time of the termination of service) at any time within 12 months of such termination, or (ii) the optionholder dies before the optionholder’s service has terminated, or within three months after termination of such service, in which case the option may be exercised (to the extent the option was exercisable at the time of the optionholder’s death) within 18 months of the optionholder’s death by the optionholder’s estate or by a person who acquired the right to


12


Table of Contents

exercise the option by bequest or inheritance. An optionholder may designate a beneficiary who may exercise the option following the optionholder’s death.
 
Other Provisions.  The option agreement may contain such other terms, provisions and conditions not inconsistent with the Directors’ Plan as determined by the Board.
 
 
Options shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the optionholder only by the optionholder. Notwithstanding the foregoing, the optionholder may, by delivering written notice to us, in a form satisfactory to us, designate a third party who, in the event of the death of the optionholder, shall thereafter be entitled to exercise the option.
 
 
Transactions not involving receipt of consideration by Volterra, such as a merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction, may change the class(es) and number of shares of common stock subject to the Directors’ Plan and outstanding options. In that event, the Directors’ Plan will be appropriately adjusted as to the class(es) and the maximum number of shares of common stock subject to the Directors’ Plan, and outstanding options will be adjusted as to the class(es), number of shares and price per share of common stock subject to such options.
 
 
The Directors’ Plan provides that, in the event of a dissolution, liquidation or sale of substantially all of the assets of Volterra, specified types of merger, or other corporate transaction, any surviving corporation will be required to either assume options outstanding under the Directors’ Plan or substitute similar options for those outstanding under the Directors’ Plan. If any surviving corporation does not assume options outstanding under the Directors’ Plan, or substitute similar options, then the options will terminate if the optionholder does not exercise it before the change in control. In addition, in the event of a change in control, the vesting and exercisability of all initial grants outstanding under the Directors’ Plan shall be accelerated in full as of a date prior to the effective time of such change in control as the Board of Directors shall determine.
 
 
The Board may suspend or terminate the Directors’ Plan without stockholder approval or ratification at any time or from time to time.
 
The Board may also amend the Directors’ Plan at any time or from time to time. However, no amendment will be effective unless approved by the stockholders of Volterra to the extent stockholder approval is necessary to satisfy applicable laws. The Board may submit any other amendment to the Directors’ Plan for stockholder approval.
 
 
Nonstatutory stock options granted under the Directors’ Plan generally have the following federal income tax consequences.
 
There are no tax consequences to the optionholder or Volterra by reason of the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock option, the optionholder normally will recognize taxable ordinary income equal to the excess of the stock’s fair market value on the date of exercise over the option exercise price. However, to the extent the stock is subject to certain types of vesting restrictions, the taxable event will be delayed until the vesting restrictions lapse unless the participant elects to be taxed on receipt of the stock. If the optionholder becomes an employee, Volterra is required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness and the satisfaction


13


Table of Contents

of a tax reporting obligation, Volterra will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the optionholder.
 
Upon disposition of the stock, the optionholder will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon exercise of the option (or vesting of the stock). Such gain or loss will be long-term or short-term depending on whether the stock was held for more than one year. Slightly different rules may apply to optionholders who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act.
 
 
The following table presents certain information with respect to options currently anticipated to be granted under the Directors’ Plan within twelve months following February 13, 2007 to all our non-employee directors as a group, assuming Proposal 2 receives the necessary stockholder approvals.

(1) The per share exercise price of the option grants will be the closing market price on the Nasdaq Global Market on the last trading day on the date prior to the date of grant.
 
(2) On the date of the 2007 Annual Meeting of Stockholders, each of the Company’s five continuing non-employee directors will automatically be granted an option to purchase 10,000 shares of our common stock. If Proposal 2 does not receive the necessary stockholder approvals, on the date of the 2007 Annual Meeting of Stockholders, each of the Company’s five continuing non-employee directors will automatically be granted an option to purchase 6,250 shares of our common stock.
 
Proposal 3
 
 
The Audit Committee of the Board has selected KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2007 and has further directed that management submit the selection of independent registered public accounting firm for ratification by the stockholders at the annual meeting. KPMG LLP has audited the Company’s financial statements since 1996. Representatives of KPMG LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
 
Neither the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG LLP as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of KPMG LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.
 
The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to ratify the selection of KPMG LLP. Abstentions will be counted toward the tabulation of votes cast on this proposal and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

The following table represents aggregate fees billed to the Company for fiscal years ended December 31, 2006 and December 31, 2005, by KPMG LLP, the Company’s independent registered public accounting firm.

Total Fees
  $ 755,000     $ 787,591  
                 
 
“Audit Fees” consist of fees billed for professional services rendered for the audit of our consolidated financial statements, audit of management’s assessment and the effectiveness of our internal control over financial reporting, and review of the interim consolidated financial statements included in quarterly reports and services that are normally provided by KPMG LLP in connection with statutory and regulatory filings or engagements.
 
“Audit-related Fees” consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” No such fees were billed during fiscal 2006 or 2005.
 
“Tax Fees” include fees for tax compliance, tax and planning and tax advice. No such fees were billed during fiscal 2006 and 2005.
 
“All Other Fees” consist of fees for products and services other than the services described above. No such fees were billed during fiscal 2006 and 2005.
 
All fees described above were approved by the Audit Committee.
 
During the fiscal year ended December 31, 2006, none of the hours billed on the Company’s financial audit by KPMG LLP were provided by persons other than KPMG LLP’s full-time permanent employees.
 
 
The Audit Committee has adopted procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, KPMG LLP. The Audit Committee generally pre-approves specified services in the defined categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual explicit case-by-case basis before the independent registered public accounting firm is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.
 
The Audit Committee has determined that the rendering of the services other than audit services by KPMG LLP is compatible with maintaining the independent registered public accounting firm’s independence.

Executive Compensation
 
 
This section discusses the material principles underlying our compensation policies and decisions regarding our Chief Executive Officer, Chief Financial Officer and three most highly compensated executive officers (the “named executive officers”) and the most important factors relevant to an analysis of these policies and decisions. It is intended to provide qualitative information regarding the manner and context in which compensation is awarded to and earned by our named executive officers and places in perspective the data presented in the tables and other quantitative information that follows this section
 
 
Our Compensation Committee (the “Committee”) is responsible for establishing and implementing Volterra’s overall compensation plans and structure, including our equity and bonus compensation program for our named executive officers. The Committee, with input from our Chief Executive Officer and an independent compensation consultant retained by the Committee, strives to create pay-for-performance compensation packages for the named executive officers that are fair and reasonable, that align the named executive officer’s long term interests with the interests of Volterra’s stockholders and that reward the individual’s contributions to Volterra’s success. The Committee is appointed by our Board of Directors, and consists entirely of directors who are “outside directors” for purposes of Section 162(m) of the Internal Revenue Code and “non-employee directors” for purposes of Rule 16b-3 under the Exchange Act. The Committee is comprised of Christopher Paisley, Edward Ross and Edward Winn.
 
The Committee annually performs a strategic review of our named executive officers’ cash compensation and equity holdings to determine whether they adequately compensate and motivate our named executive officers. The Committee’s most recent review occurred in January 2007, to establish base salary and stock option grants for 2007 and to review cash bonus plan awards under the 2006 Management Bonus Plan. Committee meetings typically have included, for all or a portion of each meeting, not only the committee members but also our Chief Executive Officer and Chief Financial Officer. For compensation decisions, including decisions regarding the grant of equity compensation to named executive officers (other than our Chief Executive Officer), the Committee typically considers the recommendations of our Chief Executive Officer and our independent compensation consultant. In setting compensation for named executive officers, in addition to reviewing such person’s performance, the Committee also considers the recent financial performance of the company, including net revenue, gross margin and operating income results, excluding the impact of stock-based compensation charges, in light of our current operating plan and prior year results.
 
 
Our compensation program is designed to attract and retain the high quality, focused executive officers that we need to drive Volterra’s continued growth and success. To achieve these goals, we have implemented an executive compensation program consisting of base salary, equity incentive compensation and a discretionary, performance-based cash bonus plan. We believe that these core compensation elements provide a clear and direct link between the named executive officer’s performance, and our goal of continuing Volterra’s growth, improving its financial performance and increasing stockholder value. In addition, we provide our executive officers with benefits that are generally available to our salaried employees. At this time, we do not believe that additional compensation such as material perquisites, severance benefits or other types of equity programs are necessary or appropriate in achieving our goals, but we acknowledge that as Volterra continues to grow, the company may be required to incorporate these features into its compensation program.
 
Our total cash compensation typically has fallen below the median levels for executive officers in comparable companies, but we believe the value of our equity compensation has allowed our total package to remain competitive in our industry. While our determination of base salaries and annual management bonus plan awards


20


Table of Contents

recognizes the individual contributions of our executive officers in assisting Volterra achieve its financial and operational goals, we want to maintain the named executive officers’ focus on the long-term performance of Volterra and the creation of stockholder value by emphasizing the equity component of compensation.
 
The Committee reviews and takes into account the industry and broader compensation surveys for guidance in establishing compensation levels, but we do not believe Volterra’s business and operations have matured to the point where the adoption of formal benchmarking practices or formulaic limitations is appropriate. As Volterra continues to grow and mature, the Committee’s primary focus is to create the proper incentives needed to satisfy our corporate objectives, and recognize that we must retain the flexibility to exceed or fall below industry or artificial benchmarks for any given named executive officer, as needed to achieve such objectives. All of our named executive officers are subject to the same elements of compensation as the other named executive officers. As described below, we have a few differences in the bonus criteria for two named executive officers, given the unique nature and function of their positions.
 
 
For our named executive officers, discussions of base salaries, option grants and target management bonus plan awards for 2006 commenced at the end of 2005 and were approved in the beginning of 2006. Management bonus plan awards for 2006 were finalized in early 2007 at the time the Committee reviewed and established compensation levels for 2007.
 
In order to tailor our compensation program to reflect the contributions of the individual officers, the Committee works closely with the Chief Executive Officer to better understand the individual strengths and contributions of each named executive officer to Volterra. As described below, the Committee also has retained an independent compensation consultant to educate the Committee and management on recent trends in executive compensation and to provide comparative compensation data, but ultimately the Committee relies on its collective experience and judgment in establishing salary levels, equity grants and management bonus plan awards. The Committee does not delegate any of its functions to others and retains the authority and responsibility for approving compensation packages.
 
In 2004, the Committee retained the services of Meyercord & Associates, an independent compensation consultant, to review the compensation packages for our named executive officers and to periodically report to the Committee on trends and new developments in compensation practices. The compensation consultant proposed target salary ranges for the Company, based in part on the median compensation packages for executive officers from a peer group of 17 companies, with similar revenues and market capitalizations:
 
         
Anadigics, Inc. 
  Atheros Communications, Inc.   California Micro Devices Corp.
Catalyst Semiconductor, Inc. 
  Centillium Communications, Inc.   Exar Corporation
Hi/fn Inc
  Leadis Technology, Inc.   Netlogic Microsystems, Inc.
Pericom Semiconductor Corp. 
  Power Integrations, Inc.   QuickLogic Corp
Sigmatel, Inc. 
  Sirenza Microdevices, Inc.   SIRF Technology Holdings, Inc.
Supertex Inc
  Tessera Technologies, Inc.    
 
In making compensation decisions for the 2006 fiscal year, the Committee reviewed proposed salaries in light of these salary target ranges, and determined that the target ranges continued to be appropriate and reasonable. The Committee and independent compensation consultant shall periodically review the list of peer companies, as appropriate, and will establish new target ranges in an attempt to ensure that the comparable data is relevant and up to date.
 
With this information as a point of reference, we reviewed the performance of our Chief Executive Officer, and approved his base salary, equity compensation and management bonus plan participation. Generally, with respect to the other Named Executive Officers, compensation is established through an iterative process between the Committee and the Chief Executive Officer, in which the Committee provides guidance to the Chief Executive Officer, and the Chief Executive Officer provides proposals and justifications for compensation packages for the Committee’s review and approval.

In response to certain recent developments affecting a number of high profile companies regarding the timing or backdating of stock option grants, the Committee determined that it was in the best interests of Volterra and its stockholders to document and formalize Volterra’s historical stock option grant practices, as previously established with input from its independent compensation consultant and outside legal counsel, to minimize the possibility of manipulating stock option grant dates or exercise prices. The Company’s documented stock option grant policy provides:
 
  •  For new hires of Volterra employees, including executive officers, option grants shall be deemed to be made on the first business day of the first month following such executive officer’s commencement of employment.
 
  •  Option grants relating to the officers’ annual “focal” reviews shall be made on the fourth business day following Volterra’s announcement of its fourth quarter financial results.
 
  •  All other option grants may be made from time to time, which grants are made at the time the Committee acts.
 
Currently, given the simplicity of our compensation program, we do not believe it is necessary to establish policies whereby compensation granted to named executive officers may be subsequently revised or recovered by Volterra in the event of a restatement of our financial results. To the extent our compensation plan continues to evolve, we will determine whether such policies are necessary or appropriate.
 
2006 Executive Compensation Components
 
For the fiscal year ended December 31, 2006, the principal components of compensation for our named executive officers were:
 
  •  base salary;
 
  •  performance-based cash bonus plan compensation; and
 
  •  equity incentive compensation.
 
We view the three components of our compensation of named executive officers as related but distinct. Although the Committee does review the aggregate total compensation represented by these components, it does not believe that significant compensation derived from one component of compensation should negate or reduce compensation from other components. We determine the appropriate level for each compensation component based in part, but not exclusively, on our view of internal equity and consistency, individual performance and other information we deem relevant. Except as described below, the Committee has not adopted any formal or informal policies or guidelines for allocating compensation between long-term and currently paid out compensation, between cash and non-cash compensation, or among different forms of compensation. This is due to the small size of our executive team and the need to tailor each named executive officer’s award to attract and retain that executive officer.
 
 
Volterra provides our named executive officers with base salary to compensate them for services rendered during the fiscal year. Base salary ranges in 2006 for our Named Executive Officers were determined for each executive officer based on his position and responsibility, with the peer group guidance and target salary ranges provided by our independent compensation consultant. Base salary ranges in 2006 were designed to fall at or below the projected median of base salaries in our peer group, although we adjusted such salaries on an individual basis as deemed appropriate by the Committee. In setting 2006 base salaries for the named executive officers, the Committee primarily considered:
 
  •  market trends provided by its independent compensation consultant;
 
  •  internal review of the named executive officer’s compensation, both individually and relative to other officers; and


22


Table of Contents

 
  •  individual performance of the named executive officer.
 
The base salary of Mr. Staszak, our President and Chief Executive Officer, was established in light of his role in and overall responsibility for the company’s attainment of certain operating goals, as reflected in the Company’s financial success. The Committee met in an executive session to review and approve Mr. Staszak’s salary, and the Committee took into account the record revenues realized by the company and improving operating margins and gross margins achieved by the company during the past year. In 2006, Mr. Staszak’s base salary equaled $298,138, a 7% increase over his 2005 base salary of $277,823.
 
Based on extensive discussions with Mr. Staszak, the Committee established base salaries for our other Named Executive Officers. These amounts were determined at levels that we concluded were appropriate based upon salaries for comparable positions within the industry and the Committee’s general experience. In determining annual salary increases, the Committee took into consideration a combination of comparable salaries within the industry and within similar-sized companies, including information provided by our independent compensation consultant. The Committee did not apply specific formulas to determine increases. Generally, executive salaries were adjusted at the first pay period following the approval of the new salary levels. In 2006, the base salaries for Mr. Staszak and our other Named Executive Officers were equal to:

For fiscal year 2006, Volterra’s Named Executive Officers were eligible to participate in an annual management bonus plan, adopted by the Committee in February 2006. The 2006 Management Bonus Plan (the “Bonus Plan”) is a cash incentive program designed to motivate and retain Volterra’s named executive officers and reward them for assisting Volterra in achieving certain financial goals for 2006. The Bonus Plan gives the Committee flexibility in establishing and modifying financial goals for Volterra, based on the net revenues, gross margin and operating income results for 2006.
 
Under the Bonus Plan, target bonuses were established for each named executive officer (except as noted below) in an amount equal to 30% of his base salary. In recognition of the significant responsibility our Vice President of Sales and Applications Engineering has in achieving the market success and attaining our financial goals, his target bonus was established at 40% of his base salary. Similarly, because the Chief Executive Officer has the ultimate responsibility for Volterra’s ability to meet its financial goals, his target bonus was established at 50% of his base salary.
 
In determining the levels of payouts under the Bonus Plan for 2006, the Committee reviewed Volterra’s financial performance for 2006, in terms of net revenue, gross margin and operating income, excluding the impact of any stock-based compensation charges. The Committee was not bound by a strict financial formula for determining the levels of bonuses to be paid to the named executive officers, but generally reviewed Volterra’s actual financial performance as compared to Volterra’s operating plan for the year and prior year results. Under the terms of the Bonus Plan, our Chief Executive Officer was eligible to receive a bonus equal to 0% to 155% of his target bonus, depending on the achievement of the financial goals established by the Committee. Unlike the other named executive officers, for which individual performance is a factor in determining the level of bonus earned, the


23


Table of Contents

Committee believes the Company’s financial performance is the best proxy for measuring the performance of our Chief Executive Officer, given his overarching responsibility for Volterra’s success. Named executive officers other than our Chief Executive Officer are also eligible to receive a bonus equal to 0% to 155% of their target bonus, but such bonuses are weighted such that two-thirds of the target bonus is based on Volterra’s financial performance and one-third is based on individual performance criteria as established by our Chief Executive Officer.
 
The Committee reviewed Volterra’s financial performance in 2006, taking note of Volterra’s record annual revenue and operating income results, in spite of some operational challenges throughout the course of the year. Based on these results, the Committee established a total bonus pool of approximately $391,000 for Volterra’s executive officers (including officers who are not named executive officers), equal to approximately 39% of the aggregate target bonus pool. After determining the Bonus Plan award for the Chief Executive Officer, the Committee directed our Chief Executive Officer to establish, justify and recommend to the Committee for review, individual bonus amounts out of the remainder of the pool for the other Named Executive Officers, in accordance with the terms of the Bonus Plan. A small preliminary award to Named Executive Officers under the Bonus Plan was made in the second quarter of 2006, and the final awards were reviewed and approved by the Committee on February 1, 2007. The aggregate total award amounts under the Bonus Plan, and the percentage of base salary are set forth below:

Equity-based compensation provides our named executive officers with the opportunity to build an equity interest the company and to share in the potential appreciation of the value of its common stock. Stock options are granted at the “fair market value” of our common stock on the date of the grant, which under the terms of our 2004 Equity Incentive Plan, is equal to the closing price of Volterra’s common stock as listed on the Nasdaq stock market on the last trading day immediately prior to the date of grant. We do not grant stock options at a discount to fair market value or reduce the exercise price of outstanding stock options except in the case of a stock split or other similar event, as defined in the Company’s equity compensation plans, nor do we grant stock options with a so-called “reload” feature or loan funds to executive officers to enable them to exercise stock options. Our long-term performance ultimately determines the value of stock options, because gains from stock option exercises are entirely dependent on the long-term appreciation of our stock price.
 
The Named Executive Officers, like our other employees, are eligible to receive option grants under our 2004 Equity Incentive Plan. Volterra’s stock option program was designed to enhance the link between the creation of stockholder value and long-term executive incentive compensation, provide an opportunity for increased equity ownership by named executive officers and maintain competitive levels of total compensation. Stock options for executive officers are typically granted upon hiring or promotion or are granted in connection with an annual “focal” review process. In 2006, none of the Named Executive Officers were new hires or recent promotions and therefore received grants in connection with the annual focal review.
 
Stock option awards are determined based on market data and various factors relating to the responsibilities of the individual named executive officers and their expected future contributions, and are established at the end of the

Table of Contents

prior fiscal year or at the beginning of the current fiscal year. We work with our compensation consultant to get information on grant levels and vesting schedules for such grants for our named executive officers. In accordance with Volterra’s option granting policies, option grants to our named executive officers were made on February 3, 2006, the fourth business day following the announcement of the prior year’s fourth quarter results.
 
Options to named executive officers, including options granted as part of the annual focal reviews, have historically vested 25% per year for each of four years. In establishing vesting schedules for option grants, the Committee believes that the retention value of stock options is maximized if the annual vesting of all stock options held by such optionholder is kept at a fairly level rate on a year to year basis. However, because our Named Executive Officers have been with Volterra for a significant period of time, the Committee did recognize that the completion of vesting of earlier option grants would result in dramatic variance in the annual vesting rate for such officers. In an effort to streamline the number of option shares that vest each year, the Committee bifurcated some of the option grants for certain Named Executive Officers, to consist of an initial option grant would begin vesting and would vest in full over the fourth year following the date of grant, and in certain instances, a second grant which would vest under a standard four-year vesting schedule.
 
 
None of our Named Executive Officers are currently entitled to payments upon termination of employment or in connection with a change in control. All options to purchase common stock issued to our Named Executive Officers may be subject to accelerated vesting upon a change of control as follows. In the event of specified corporate transactions, all outstanding options and stock appreciation rights under the 2004 Equity Incentive Plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume, continue or substitute such awards, then (i) with respect to any such options and stock appreciation rights that are held by participants then performing services for us or our affiliates, the vesting and exercisability provisions of such options and stock appreciation rights will be accelerated in full and such options and stock appreciation rights will be terminated if not exercised prior to the effective date of the corporate transaction, and (ii) all other outstanding options and stock appreciation rights will be terminated if not exercised prior to the effective date of the corporate transaction. Other forms of equity awards under the 2004 Equity Incentive Plan such as stock purchase awards may have their repurchase or forfeiture rights assigned to the surviving or acquiring entity (or its parent company). If such repurchase or forfeiture rights are not assigned, then such equity awards will become fully vested. Following specified change in control transactions, the vesting and exercisability of specified equity awards generally will be accelerated only if the awardee’s award agreement so specifies. The potential benefits described above are available generally to all salaried employees.
 
 
Volterra does not provide its Named Executive Officers with any other compensation, material perquisites or material personal benefits. Volterra provides Named Executive Officers with benefits generally available to all employees, including life insurance premiums and subsidized gym memberships, and the aggregate annual value of these benefits does not exceed $2,500 per year.
 
Volterra maintains a 401(k) plan in which substantially all of its employees, including named executive officers, are entitled to participate. Employees may contribute their own funds, as salary deductions, on a pre-tax basis, up to certain specified plan limits and other government limitations. Volterra also maintains its 2004 Employee Stock Purchase Plan in which all eligible employees, including named executive officers, may purchase Volterra common stock at 85% of fair market value, subject to specified limits and conditions,.
 
 
 
Section 162(m) of the Internal Revenue Code of 1986 limits us to a deduction for federal income tax purposes of up to $1 million of compensation paid to certain named executive officers in a taxable year. Compensation above $1 million may be deducted if it is “performance-based compensation.” Stock option awards under our 2004 Equity


25


Table of Contents

Incentive Plan, to the extent the board of directors or a committee of the board of directors granting such stock awards is composed solely of “outside directors,” are performance-based compensation within the meaning of Section 162(m) and, as such, are fully deductible. As noted above, Volterra’s compensation policy is primarily based upon the practice of pay-for-performance. To maintain flexibility in compensating executive officers in a manner designed to promote varying corporate goals, the Committee has not adopted a policy requiring all compensation to be deductible. However, the Committee intends to continue to evaluate the effects of the compensation limits of Section 162(m) and believes that Volterra should be able to continue to manage its executive compensation program for Named Executive Officers so as to preserve the related federal income tax deductions, although individual exceptions may occur, in a manner consistent with the best interests of our company and our stockholders.
 
 
Beginning on January 1, 2006, Volterra began accounting for stock-based payments under its stock option plans in accordance with the requirements of Statement of Financial Accounting Standards (SFAS) No. 123R. Under SFAS No. 123R, we are required to estimate and record an expense for each award of equity compensation over the vesting period of the award. Compensation expense and tax considerations relating to the expense of stock options under SFAS 123R are one of the many factors considered in the determination of stock option awards.
 
 
Our compensation strategy is necessarily tied to our stage of development. Accordingly, the specific direction, emphasis and components of our executive officer compensation program continue to evolve in parallel with the evolution of our business strategy. Our Compensation Discussion and Analysis will, in the future, reflect these evolutionary changes.
 
 
The Compensation Committee of Volterra has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated into Volterra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

Volterra does not provide pension benefits or any nonqualified deferred compensation to any executive officer or other employee.
 
 
Volterra uses a combination of cash and stock-based incentive compensation to attract and retain qualified candidates to serve on the Board. In setting director compensation, Volterra considers the significant amount of time that Directors expend in fulfilling their duties to Volterra as well as the skill-level required by Volterra of members of the Board. Two of our directors, Mr. Staszak and Dr. Stratakos, are employees of the Company.
 
 
For the fiscal year ended December 31, 2006, members of the Board who are not employees of Volterra are entitled to receive the following cash compensation in connection with their service on the Board of Directors and committees of the Board of Directors. These payments were made in equal quarterly installments, through the third quarter of 2006.

Under the terms of the 2004 Non-Employee Directors’ Stock Option Plan, upon being elected or appointed for the first time as a non-employee director, such person shall receive an initial grant to purchase fifteen thousand six hundred (15,600) shares of common stock, and at each annual meeting, each non-employee director shall automatically receive an annual grant to purchase six thousand two hundred fifty (6,250) shares of common stock. The initial grant shall vest in equal annual installments over a three year period, and annual grants shall vest one year after the date of grant. On May 18, 2006, the non-employee directors received an option grant to purchase 6,250 shares of common stock, at an exercise price of $14.36. Pursuant to the terms of our 2004 Non-Employee Directors’ Stock Option Plan, the exercise price of our granted options is equal to the closing price of Volterra’s common stock as listed on the Nasdaq stock market on the last trading day immediately prior to the date of grant.
 
As described in Proposal 2, Volterra is soliciting approval of an amendment to the 2004 Non-Employee Directors’ Stock Option Plan, to change the number of option shares issuable to non-employee directors under the initial grant from 15,600 shares to 30,000 shares and to change the number of option shares issuable to non-employee directors under the annual grants, from 6,250 shares to 10,000 shares. If approved, this change would be effective for the grants made to non-employee directors on the date of the annual meeting.
 
In the event that there is a specified type of change in our capital structure, such as a stock split, the number of shares reserved under the Directors’ Plan and the number of shares subject to, and exercise price of, all outstanding stock options will be appropriately adjusted.
 
In the event of specified corporate transactions, all outstanding options under the Directors’ Plan may be assumed, continued or substituted by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume, continue or substitute such options, then (i) with respect to any such options held by optionees then performing services for us or our affiliates, the vesting and exercisability of such options will be accelerated in full and such options will be terminated if not exercised prior to the effective date of such corporate transaction and (ii) all other such outstanding options will be terminated if not exercised prior to the effective date of the corporate transaction. In the event of specified changes in control, the vesting and exercisability of outstanding options under the Directors’ Plan granted to non-employee directors whose service has not terminated prior to such change in control, other than as a condition of such change in control, will be accelerated in full.
 
 
The table below summarizes the compensation paid by Volterra to Directors for the fiscal year ended December 31, 2006. Mr. Staszak, Volterra’s President and Chief Executive Officer, is not included in this table as he is an employee of Volterra and thus receives no compensation for his services as a Director. The compensation paid to Dr. Stratakos consists of his salary, cash bonus plan compensation and equity incentive grants in his capacity as the Company’s Vice President of Advanced Research & Development and Chief Technology Officer. The non-employee directors did not receive any stock awards and Volterra did not offer participation to the non-employee directors in any non-equity incentive plan compensation, any pension or any nonqualified deferred compensation plan or program.

Table of Contents

 
(1) As of December 31, 2006, the non-employee directors held options to purchase shares of Volterra’s common stock, in the following amounts: Alan King: 12,500; Mel Friedman: 37,500; Christopher Paisley: 60,000; Edward Ross: 34,500; and Edward Winn: 37,500. As of December 31, 2006, Dr. Stratakos held options to purchase 442,500 shares of Volterra’s common stock.
 
(2) The amounts in column (b) reflect the dollar amount recognized for financial statement reporting purposes for the fiscal year ended December 31, 2006, in accordance with SFAS 123R of options granted to the executive, and therefore may include options granted in prior years. The amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. Assumptions used in the calculation of this amount are included in footnote 2(j) to Volterra’s audited financial statements for the fiscal year ended December 31, 2006 included in Volterra’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 8, 2007.
 
(3) Consists of partial reimbursements for continuing director education.
 
(4) Consists of Dr. Stratakos’ 2006 salary as an employee of the Company, equal to $188,116, and cash payments under the Company’s 2006 Management Bonus Plan, equal to $32,938. Dr. Stratakos does not receive any other payment in connection with his role as a director of the Company. This amount also does not include de minimis benefits generally available to executive officers, including the named executive officers.
 
 
As previous noted, our Compensation Committee consists of Messrs. Ross, Paisley, and Winn. None of our executive officers serve as a member of the board of directors or compensation committee of any entity that has one or more executive officers who serve on our Board or Compensation Committee.
 
Certain Relationships and Related Transactions
 
 
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 attorneys’ 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.
 
 
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 2006, we made payments to TSMC in the amount of $22.8 million. We believe that our transactions with TSMC were on terms no less favorable than could be obtained from other semiconductor foundries.
 
 
The company has adopted a Code of Conduct which generally describes the Company’s policy relating to conflicts of interest. In an effort to further avoid conflicts of interests with our executive officers or directors, or the appearance of such a conflict, the Company has also adopted a Related Persons Transactions Policy applicable to them. Under such Related Party Transactions Policy, a “related person transaction” is described as a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the company and any “related person” are, were or will be participants in which the amount involved exceeds $120,000,

unless such transaction is not required to be disclosed under Item 404 of Regulation S-K under the Securities Exchange Act of 1934, as amended. Under such policy, the Company shall gather information relating to the immediate family members of the officers and directors, to determine whether there are any transactions or proposed transactions that must be approved or ratified. Under the policy, upon learning of a proposed related party transaction, the Company shall submit the terms of such transaction to the Audit Committee for consideration. The Audit Committee will determine, in light of known circumstances at the time, whether such transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders, as determined by the Audit Committee in its good faith exercise of its discretion.
 
The Committee has determined that the Company has not entered into any transactions that are considered Related Party Transactions.
 
 
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement and annual report addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.
 
This year, a number of brokers with account holders who are Volterra Semiconductor Corporation stockholders will be “householding” our proxy materials. A single proxy statement and annual report will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, please notify your broker and direct your written request to Investor Relations, Volterra Semiconductor Corporation, 3839 Spinnaker Court, Fremont, CA 94538.

The purchase price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes).
 
(d) Transferability.  Except as otherwise provided for in this Section, an Option is transferable only by will or by the laws of descent and distribution and exercisable only by the Optionholder during the life of the Optionholder. However, an Option may be transferred for no consideration upon written consent of the Board if (i) at the time of transfer, a Form S-8 registration statement under the Securities Act is available for the issuance of shares by the Company upon the exercise of such transferred Option or (ii) the transfer is to the Optionholder’s employer at the time of transfer or an affiliate of the Optionholder’s employer at the time of transfer. Any such transfer is subject to such limits as the Board may establish, and subject to the transferee agreeing to remain subject to all the terms and conditions applicable to the Option prior to such transfer. The forgoing right to transfer the Option shall apply to the right to consent to amendments to the Stock Option Agreement for such Option.

(e) Vesting.  Options shall vest as follows:
 
(i) Initial Grants:
 
(1) Initial Grants made prior to May 18, 2006: 1/4th of the shares shall vest one year after the date of grant and 1/16th of the shares shall vest quarterly thereafter over three (3) years.

Any unvested shared of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option.
 
(g) Termination Of Continuous Service.  In the event that an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability or upon a Change in Control), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service) but only within such period of time ending on the earlier of (i) the expiration of the term of the Option as set forth in the Option Agreement or (ii) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter

period specified in the Option Agreement). If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.
 
(h) Extension Of Termination Date.  If the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited at any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option as set forth in the Option Agreement or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such registration requirements.
 
(i) Disability Of Optionholder.  In the event an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise it as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate.
 
(j) Death Of Optionholder.  In the event (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the three-month period after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise the Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate.
 
(k) Termination Upon Change In Control.  In the event that an Optionholder’s Continuous Service terminates as of, or within twelve (12) months following a Change in Control, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service) within such period of time ending on the earlier of (i) the expiration of the term of the Option as set forth in the Option Agreement or (ii) the date twelve (12) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter period specified in the Option Agreement). If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.
 
 
The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Options and to issue and sell shares of Common Stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Option or any stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Options unless and until such authority is obtained.
 
 
Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company.

The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares upon the exercise or acquisition of stock under the Option has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock.

In the event that any surviving corporation or acquiring corporation (or its parent company) does not assume or continue all such outstanding Options or substitute similar stock options for such outstanding Options, then with respect to Options that have been not assumed, continued or substituted and are held by Optionholders whose Continuous Service has not terminated prior to the effective time of the Corporate Transaction, the vesting of such Options (and, if applicable, the time at which such Options may be exercised) shall (contingent upon the effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), and the Options shall terminate if not exercised (if applicable) at or prior to such effective time. With respect to any other Options outstanding under the Plan that have not been assumed, continued or substituted, the vesting of such Options (and, if applicable, the time at which such Options may be exercised) shall not be accelerated unless otherwise provided in Section 11(d) or in a written agreement between the Company or any Affiliate and the holder of such Options, and such Options shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction.
 
(d) Change In Control.  If a Change in Control occurs and an Optionholder’s Continuous Service with the Company has not terminated immediately prior to the effective time of the Change in Control, then, immediately prior to the effective time of such Change in Control (and contingent upon the effectiveness of the Change in Control), the vesting and exercisability of an Optionholder’s Options shall be accelerated in full. In the event that an Optionholder is required to resign his or her position as a Non-Employee Director as a condition of a Change in Control, the outstanding Options of such Optionholder shall become fully vested and exercisable immediately prior to the effectiveness of such resignation (and contingent upon the effectiveness of the Change in Control).
 
(e) Parachute Payments.  If the acceleration of the vesting and exercisability of Options provided for in Section 11(c), together with payments and other benefits of an Optionholder, (collectively, the “Payment”) (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, or any comparable successor provisions, and (ii) but for this Section 11(e) would be subject to the excise tax imposed by Section 4999 of the Code, or any comparable successor provisions (the “Excise Tax”), then such Payment shall be either (1) provided to such Optionholder in full, or (2) provided to such Optionholder as to such lesser extent that would result in no portion of such Payment being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local and foreign income and employment taxes, the Excise Tax, and any other applicable taxes, results in the receipt by such Optionholder, on an after-tax basis, of the greatest amount of the Payment, notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.
 
Unless the Company and such Optionholder otherwise agree in writing, any determination required under this Section 11(e) shall be made in writing in good faith by the Accountant. If a reduction in the Payment is to be made as provided above, reductions shall occur in the following order unless the Optionholder elects in writing a different order (provided, however, that such election shall be subject to Company approval if made on or after the date that triggers the Payment or a portion thereof): reduction of cash payments; cancellation of accelerated vesting of Options; reduction of employee benefits. If acceleration of vesting of Options is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of date of grant of Options (i.e., earliest granted Option cancelled last) unless the Optionholder elects in writing a different order for cancellation.
 
For purposes of making the calculations required by this Section 11(e), the Accountant may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Code and other applicable legal authority. The Company and the Optionholder shall furnish to the Accountant such information and documents as the Accountant may reasonably request in order to make such a determination. The Company shall bear all costs the Accountant may reasonably incur in connection with any calculations contemplated by this Section 11(e). If, notwithstanding any reduction described above, the Internal Revenue Service (the “IRS”) determines that the Optionholder is liable for the Excise Tax as a result of the Payment, then the Optionholder shall be obligated to pay back to the Company, within thirty (30) days after a final

IRS determination or, in the event that the Optionholder challenges the final IRS determination, a final judicial determination, a portion of the Payment equal to the “Repayment Amount.” The Repayment Amount with respect to the Payment shall be the smallest such amount, if any, as shall be required to be paid to the Company so that the Optionholder’s net after-tax proceeds with respect to the Payment (after taking into account the payment of the Excise Tax and all other applicable taxes imposed on the Payment) shall be maximized. The Repayment Amount with respect to the Payment shall be zero if a Repayment Amount of more than zero would not result in the Optionholder’s net after-tax proceeds with respect to the Payment being maximized. If the Excise Tax is not eliminated pursuant to this paragraph, the Optionholder shall pay the Excise Tax.
 
Notwithstanding any other provision of this Section 11(e), if (i) there is a reduction in the Payment as described above, (ii) the IRS later determines that the Optionholder is liable for the Excise Tax, the payment of which would result in the maximization of the Optionholder’s net after-tax proceeds of the Payment (calculated as if the Payment had not previously been reduced), and (iii) the Optionholder pays the Excise Tax, then the Company shall pay or otherwise provide to the Optionholder that portion of the Payment that was reduced pursuant to this Section 11(e) contemporaneously or as soon as administratively possible after the Optionholder pays the Excise Tax so that the Optionholder’s net after-tax proceeds with respect to the Payment are maximized.
 
If the Optionholder either (i) brings any action to enforce rights pursuant to this Section 11(e), or (ii) defends any legal challenge to his or her rights under this Section 11(e), the Optionholder shall be entitled to recover attorneys’ fees and costs incurred in connection with such action, regardless of the outcome of such action; provided, however, that if such action is commenced by the Optionholder, the court finds that the action was brought in good faith.
 
 
(a) Amendment Of Plan.  The Board, at any time and from time to time, may amend the Plan. However, except as provided in Section 11 relating to adjustments upon changes in Common Stock, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of applicable laws.
 
(b) Stockholder Approval.  The Board, in its sole discretion, may submit any other amendment to the Plan for stockholder approval.
 
(c) No Impairment Of Rights.  Rights under any Option granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing.
 
(d) Amendment Of Options.  The Board, at any time, and from time to time, may amend the terms of any one or more Options; provided, however, that the rights under any Option shall not be impaired by any such amendment unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing.
 
 
(a) Plan Term.  The Board may suspend or terminate the Plan at any time. No Options may be granted under the Plan while the Plan is suspended or after it is terminated.
 
(b) No Impairment Of Rights.  Suspension or termination of the Plan shall not impair rights and obligations under any Option granted while the Plan is in effect except with the written consent of the Optionholder.
 
 
The Plan shall become effective on the IPO Date, but no Option shall be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.
 
15.  Choice Of Law.
 
The law of the state of Delaware shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of laws rules.
