PROXY STATEMENT

FOR THE 2011 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON JUNE 1, 2011

QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING

Why am I receiving these materials?

We sent you this Proxy Statement and the enclosed proxy card because the Board of Directors (the “Board”) of Masimo Corporation (sometimes referred to as “we”, “Masimo” or the “Company”) is soliciting your proxy to vote at the 2011 Annual Meeting of Stockholders, or any adjournment or postponement thereof (the “Annual Meeting”). You are invited to attend the Annual Meeting and we request that you vote on the proposals described in this Proxy Statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card or submit your proxy through the Internet or by telephone according to the instructions contained in the enclosed proxy card.

We intend to mail this Proxy Statement and the accompanying proxy card on or about April 27, 2011 to all stockholders of record entitled to vote at the Annual Meeting.

When and where will the Annual Meeting be held?

The Annual Meeting will be held on June 1, 2011, at 10:00 a.m. Pacific Time at our offices located at 40 Parker, Irvine, California 92618. Directions are set forth on the back of this Proxy Statement.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 18, 2011 will be entitled to vote at the Annual Meeting. At the close of business on this record date, there were 59,759,684 shares of common stock outstanding and entitled to vote and no shares of preferred stock outstanding or entitled to vote. The holders of common stock will have one vote for each share of common stock they owned as of the close of business on April 18, 2011.

Stockholder of Record: Shares Registered in Your Name

If at the close of business on April 18, 2011 your shares of common stock were registered directly in your name with our transfer agent, Computershare, Inc., then you are a stockholder of record of these shares. As a stockholder of record, you may vote either in person at the Annual Meeting or by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to complete and return the enclosed proxy card or submit your proxy through the Internet or by telephone by following the instructions provided in the proxy card to ensure that your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If at the close of business on April 18, 2011 your shares of common stock 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 the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. Certain of these institutions offer the ability to direct your agent how to vote through the Internet or by telephone. You are also invited to attend the Annual Meeting. However, because

you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy issued in your name from your broker, bank or other agent considered the stockholder of record of the shares.

What am I voting on?

There are five matters scheduled for a vote at the Annual Meeting:

•

Election of two Class I nominees for director to serve until our 2014 annual meeting of stockholders or until their successors are duly elected and qualified;

•

Ratification of the selection by the Audit Committee of our Board of Directors of Grant Thornton LLP as our independent auditors for our fiscal year ending December 31, 2011;

•

Advisory (nonbinding) vote on the compensation of our named executive officers, as presented in this Proxy Statement;

•

Advisory (nonbinding) vote on the frequency of the stockholder advisory vote to approve named executive officer compensation; and

•

A shareholder proposal regarding adoption of a majority voting standard for director elections.

Will there be any other items of business on the agenda?

Aside from the election of directors, ratification of the selection of the independent registered public accounting firm, advisory votes on the compensation of our named executive officers, the frequency with which executive compensation will be subject to a stockholder advisory vote, and the shareholder proposal regarding adoption of a majority voting standard for director elections, the Board knows of no matters to be presented at the Annual Meeting. If any other matter should be presented at the Annual Meeting upon which a vote properly may be taken, shares represented by all proxies received by the Board will be voted with respect thereto in accordance with the judgment of the persons named as attorneys-in-fact in the proxies.

What is the Masimo Board’s voting recommendation?

Masimo’s Board recommends that you vote your shares:

•

“For” both of the nominees to the Board;

•

“For” the ratification of the Audit Committee’s selection of Grant Thornton LLP as Masimo’s independent registered public accounting firm;

•

“For” the approval, on an advisory basis, of the compensation of our named executive officers, as set forth in this Proxy Statement;

•

“For” the approval, on an advisory basis, of a triennial (3 year) advisory vote to approve named executive compensation; and

•

“Against” the shareholder proposal regarding adoption of a majority voting standard for director elections.

How do I vote?

For the election of our Class I directors, you may either vote “For” both nominees to the Board or you may “Withhold” your vote for any nominee you specify. For the ratification of the selection of our independent auditors, you may vote “For” or “Against” or abstain from voting. For the advisory vote on the compensation of our named executive officers, you may vote “For” or “Against” or abstain from voting. For the advisory vote on the frequency with which executive compensation will be subject to a stockholder advisory vote, your vote may be cast for every “1 Year,” “2 Years,” or “3 Years,” or you may abstain from voting. For the shareholder

proposal regarding adoption of a majority voting standard for director elections, you may vote “For” or “Against” or abstain from voting. The procedures for voting are described below, based upon your form of ownership.

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the Annual Meeting. We will give you a ballot when you arrive.

If you do not wish to vote in person or you will not be attending the Annual Meeting, you may vote by proxy. You may vote by proxy using the enclosed proxy card, vote by proxy on the Internet or vote by proxy over the telephone. The procedures for voting by proxy are as follows:

•

To vote by proxy using the enclosed proxy card, complete, sign and date your proxy card and return it promptly in the envelope provided.

•

To vote by proxy on the Internet, go to www.investorvote.com/MASI and follow the instructions set forth on the Internet site.

•

To vote by proxy over the telephone, dial the toll-free phone number listed on your proxy card under the heading “Vote by telephone” using a touch-tone phone and follow the recorded instructions.

If you vote by proxy, your vote must be received by 1:00 a.m. Central Time on June 1, 2011, to be counted.

We provide Internet and telephone proxy voting with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet and telephone access, such as usage charges from Internet access providers and telephone companies.

Beneficial Owner: Shares Registered in the Name of Your Broker, Bank or Other Agent

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 Masimo. To ensure that your vote is counted, simply complete and mail the proxy card or, if provided by your agent, follow the instructions for submitting your proxy through the Internet or by phone. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent in whose name the shares are registered. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy form.

How do I vote my Masimo shares held through the Masimo Retirement Savings Plan?

If you hold shares of Masimo common stock through the Masimo Retirement Savings Plan (the “Savings Plan”) as of the record date, your proxy will also serve as a voting instruction for Principal Financial Group (“Principal”), which serves as the administrator of the Savings Plan, with respect to shares of Masimo common stock that you hold through the Savings Plan. You should sign the proxy card and return it in the enclosed envelope, or you may submit your proxy over the Internet or by telephone by following the instructions on the enclosed card. We will notify Principal of the manner in which you have directed your Savings Plan shares to be voted. Principal will vote your Savings Plan shares as of the record date in the manner that you direct. If we do not receive your voting instructions from you by May 26, 2011, Principal will vote your Savings Plan shares as of the record date in the same manner, proportionally, as it votes the other shares of common stock for which proper and timely voting instructions of other Savings Plan participants have been received by Principal.

How many votes do I have?

On each matter to be voted upon, holders of common stock will have one vote for each share of common stock they owned as of the close of business on April 18, 2011, the record date for the Annual Meeting.

Will my vote be kept confidential?

Proxies, ballots and voting tabulations are handled on a confidential basis to protect your voting privacy. This information will not be disclosed, except as required by law.

Who is paying for this proxy solicitation?

We will bear the cost of soliciting proxies for the Annual Meeting. We will ask banks, brokerage houses, fiduciaries and custodians holding shares of Masimo common stock in their names for others to send proxy materials to and obtain proxies from the beneficial owners of such shares, and we will reimburse them for their reasonable expenses in doing so. In addition, we may retain Georgeson Inc. to act as a proxy solicitor in conjunction with the Annual Meeting. If we retain Georgeson, we will agree to pay the firm a fee not to exceed $10,000, plus reasonable expenses, costs and disbursements for proxy solicitation services. We and our directors, officers and regular employees may supplement the proxy solicitor’s solicitation of proxies by mail, personally, by telephone or by other appropriate means. No additional compensation will be paid to directors, officers or other regular employees for such services.

What does it mean if I receive more than one proxy card?

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.

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy in any one of three ways:

•

You may submit another properly completed and executed proxy card with a later date;

•

You may submit a new proxy through the Internet or by telephone (1-800-652-VOTE) (your latest Internet or telephone instructions submitted prior to the deadline will be followed);

•

You may send a written notice that you are revoking your proxy to our Corporate Secretary, c/o Masimo Corporation, 40 Parker, Irvine, California 92618; or

•

You may attend the Annual Meeting and vote in person. However, simply attending the Annual Meeting will not, by itself, revoke your proxy.

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, follow the voting instructions from that organization included with these proxy materials, or contact that organization to determine how you may revoke your proxy.

Votes will be counted by the inspector of election appointed for the Annual Meeting.

How are my shares voted if I give no specific instruction?

We must vote your shares as you have instructed. If there is a matter on which a stockholder of record has given no specific instruction but has authorized us generally to vote the shares, they will be voted as follows:

•

“For” the election of the two Class I director nominees;

•

“For” the ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2011;

•

“For” the approval, on an advisory basis, of the compensation of our named executive officers, as set forth in this Proxy Statement;

•

“For” a triennial (3 year) advisory vote to approve named executive compensation; and

•

“Against” the shareholder proposal regarding adoption of a majority voting standard for director elections.

This authorization would exist, for example, if a stockholder of record merely signs, dates and returns the proxy card but does not indicate how its shares are to be voted on one or more proposals. If other matters properly come before the Annual Meeting and you do not provide specific voting instructions, your shares will be voted in the discretion of the proxies.

If your shares are held in street name, see “What is a broker non-vote?” below regarding the ability of banks, brokers, and other such holders of record to vote the uninstructed shares of their customers or other beneficial owners in their discretion and regarding broker non-votes.

What is a broker non-vote?

Under rules that govern banks, brokers and others who have record ownership of company stock held in brokerage accounts for their clients who beneficially own the shares, these banks, brokers and other such holders who do not receive voting instructions from their clients have the discretion to vote uninstructed shares on certain matters (“discretionary matters”) but do not have discretion to vote uninstructed shares as to certain other matters (“non-discretionary matters”). A broker may return a proxy card on behalf of a beneficial owner from whom the broker has not received voting instructions that casts a vote with regard to discretionary matters but expressly states that the broker is not voting as to non-discretionary matters. The broker’s inability to vote with respect to the non-discretionary matters with respect to which the broker has not received voting instructions from the beneficial owner is referred to as a “broker non-vote.”

What are the voting requirements that apply to the proposals discussed in this Proxy Statement?


Proposal	Vote Required		Discretionary Voting Allowed?
1. Election of Directors		Plurality		No
2. Ratification of Auditors		Majority		Yes
3. Advisory Vote on Executive Compensation Program		Majority		No
4. Advisory Vote on Frequency of Advisory Vote on Executive Compensation Program		Plurality		No
5. Shareowner Proposal		Majority		No

A “plurality” means, with regard to the election of directors, that the two nominees for director receiving the greatest number of “for” votes from our shares entitled to vote will be elected. A “plurality” with regard to the advisory vote on the frequency of the shareowner vote on executive compensation program means that the option (every one, two or three years) receiving the greatest number of “for” votes will be considered the frequency recommended by stockholders.

A “majority” means that a proposal receives a number of “for” votes that is a majority of the shares of common stock present in person or represented by proxy and entitled to vote at the Annual Meeting.

“Discretionary voting” occurs when a bank, broker, or other holder of record does not receive voting instructions from the beneficial owner and votes those shares in its discretion on any proposal as to which rules permit such bank, broker, or other holder of record to vote. As noted above, when banks, brokers, and other holders of record are not permitted under the rules to vote the beneficial owner’s shares, the affected shares are referred to as “broker non-votes.”

Although the advisory votes on Proposals 3 and 4 are non-binding, as provided by law, our Board will review the results of the votes and, consistent with our record of shareowner engagement, will take the results into account in making a determination concerning executive compensation and the frequency of such advisory votes.

What is the effect of withhold authority votes, abstentions and broker non-votes?

Withhold Votes: Shares subject to instructions to withhold authority to vote on the election of directors will not be voted. This will have no effect on the election of directors because, under plurality voting rules, the two director nominees receiving the highest number of “for” votes will be elected.

Abstentions: Under Delaware law (under which Masimo is incorporated), abstentions are counted as shares present and entitled to vote at the Annual Meeting. Therefore, abstentions will have the same effect as a vote “against”: Proposal No. 2—Ratification of Auditors; Proposal No. 3—Advisory Vote on Executive Compensation Program; and Proposal No. 5— Shareowner Proposal. Because the voting requirement applicable to Proposal No. 4—the frequency of the shareowner vote on the compensation of our named executive officers is a plurality of the shares voted on the various options, an abstention with regard to this proposal will have no effect on the outcome of the vote.

Broker Non-Votes: As a result of a change in rules related to discretionary voting and broker non-votes, banks, brokers, and other such record holders are no longer permitted to vote the uninstructed shares of their customers on a discretionary basis in the election of directors or on executive compensation program matters (they have long been prohibited from doing so on shareowner proposals that are opposed by management). Because broker non-votes are not considered under Delaware law to be entitled to vote at the Annual Meeting, they will have no effect on the outcome of the vote on: Proposa1 1—the election of directors; Proposal No. 3—Advisory Vote on Executive Compensation Program; Proposal No. 4—the frequency of the shareowner vote on the compensation of our named executive officers; and Proposal No. 5— Shareowner Proposal. As a result, if you hold your shares in street name and you do not instruct your bank, broker, or other such holder how to vote your shares in the election of directors, on the two advisory votes related to our executive compensation program and on the shareowner proposal, no votes will be cast on your behalf on these proposals. Therefore, it is critical that you indicate your vote on these proposals if you want your vote to be counted. The proposal to ratify the selection of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2011 should be considered a routine matter. Therefore, your broker will be able to vote on this proposal even if it does not receive instructions from you, so long as it holds your shares in its name.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of our outstanding shares of common stock are represented by votes at the Annual Meeting or by proxy. At the close of business on April 18, 2011, the record date for the Annual Meeting, there were 59,759,684 shares of common stock outstanding. Thus, a total of 59,759,684 shares are entitled to vote at the Annual Meeting and holders of common stock representing at least 29,879,843 votes must be represented at the Annual Meeting or by proxy to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or if one is submitted on your behalf by your broker, bank or other agent) or if you vote in person at the Annual Meeting. Votes withheld from a director nominee and abstentions will be counted towards the quorum requirement. Broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairman of the meeting or a majority of the shares present at the Annual Meeting may adjourn the Annual Meeting to another date.

Who will count the votes?

The votes will be counted, tabulated and certified by Computershare, Inc., Masimo’s transfer agent and registrar for the company’s common stock.

I also have received a copy of Masimo Corporation’s Annual Report on Form 10-K. Is that a part of the proxy materials?

Our Annual Report on Form 10-K for the fiscal year ended January 1, 2011, as filed with the Securities and Exchange Commission (the “SEC”) on February 16, 2011, accompanies this Proxy Statement. This document constitutes our Annual Report to Stockholders, and is being made available to all stockholders entitled to receive notice of and to vote at the Annual Meeting. Except as otherwise stated, the Annual Report on Form 10-K is not incorporated into this Proxy Statement and should not be considered proxy solicitation material.

How can I find out the results of the voting at the Annual Meeting?

Voting results are expected to be announced at the Annual Meeting and will also be disclosed in a Current Report on Form 8-K (the “Form 8-K”) that we will file with the SEC within four business days of the date of the Annual Meeting. In the event the results disclosed in our Form 8-K are preliminary, we will subsequently amend the Form 8-K to report the final voting results within four business days of the date that such results are known.

When are stockholder proposals due for next year’s annual meeting of stockholders?

Stockholders may submit proposals on matters appropriate for stockholder action at the next annual meeting of the Company’s stockholders consistent with Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). To be considered for inclusion in proxy materials for our 2012 Annual Meeting of Stockholders, a stockholder proposal must be submitted in writing no later than December 29, 2011 to our Corporate Secretary at 40 Parker, Irvine, California 92618. If you wish to submit a proposal that is not to be included in the proxy materials for our 2012 Annual Meeting of Stockholders, your proposal generally must be submitted in writing to the same address no later than March 13, 2012, but no earlier than February 12, 2012. Please review our bylaws, which contain additional requirements regarding advance notice of stockholder proposals. You may view our bylaws by visiting the SEC’s Internet website at www.sec.gov.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Overview

Masimo’s Board of Directors presently has six members and is divided into three classes, designated Class I, Class II and Class III. Each class consists of two 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 in office (even though the remaining directors may constitute less than a quorum). A director elected by our Board of Directors to fill a vacancy in a Class, including a vacancy created by an increase in the number of directors, shall serve for the remainder of the full term of that Class and until the director’s successor is elected and qualified or until the director’s earlier death, resignation or removal.

The term of office of the two Class I directors expires in 2011. Each of the nominees listed below is currently a director of Masimo. If elected at the Annual Meeting, each of these nominees would serve until the 2014 annual meeting of stockholders and until his successor is elected and qualified or, if sooner, until the director’s death, resignation or removal. It is Masimo’s policy to invite directors and nominees for director to attend the Annual Meeting either in person, by telephone or by webcast.

Directors are elected by a plurality of the votes present at the Annual Meeting or by proxy and entitled to vote at the Annual Meeting. The two nominees receiving the most “For” votes (among votes properly cast in person or by proxy) will be elected. If no contrary indication is made, shares represented by executed proxies will be voted “For” the election of the two nominees named below or, if either nominee becomes unavailable for election as a result of an unexpected occurrence, “For” the election of a substitute nominee designated by our Board of Directors. Each nominee has agreed to serve as a director if elected and we have no reason to believe that any nominee will be unable to serve.

There are no family relationships between or among any of our officers or directors.

Nominees

The following sets forth the names and ages, as of February 28, 2011, of the nominees for director and each director whose term will continue after the Annual Meeting, and certain other information about them.

Nominees for Election for a Three-year Term Expiring at the 2014 Annual Meeting of Stockholders

Steven J. Barker, M.D., Ph.D., age 66, has served as a member of our Board since October 2005. Dr. Barker has served as the Professor and Head of Anesthesiology, University of Arizona College of Medicine since October 1995. From August 1990 to October 1995, Dr. Barker served as Chairman of Anesthesiology at the University of California, Irvine. He also holds a joint appointment as Professor of Mechanical and Aerospace Engineering. Dr. Barker is an oral examiner for the American Board of Anesthesiology, and is the Section Editor for Technology, Computing, and Simulation in the journal of Anesthesia and Analgesia. He also holds a B.S. in Physics and an M.S. and a Ph.D. in Mechanical Engineering from the California Institute of Technology and an M.D. from the University of Miami. Our Nominating and Corporate Governance Committee believes Dr. Barker’s academic and medical background, as well as his in-depth knowledge of the healthcare industry and hospital operations, academic administration and managed care industry, provide him with a critical perspective regarding Masimo’s products, technologies and prospects. His medical background, including his expertise in anesthesiology, are particularly relevant to Masimo when the Company evaluates its products and technologies. In addition, Dr. Barker is able to provide us with the unique perspective of a physician.

Sanford Fitch, age 70, has served as a member of our Board since November 2006. Mr. Fitch was a director and the chair of the audit committee of Fox Hollow Technologies Inc., a medical device company, from August 2004 until the company was acquired by ev3 Inc. in October 2007. From March 2001 to December 2002, Mr. Fitch served as Vice President of Finance and Chief Financial Officer of Alvesta, a fiber optic component manufacturing company. From March 2000 to December 2000, Mr. Fitch served as Senior Vice President of Finance and Chief Financial Officer of Cruel World, an internet-based recruiting company. From December 1994 to November 1998, Mr. Fitch served as Senior Vice President of Finance and Operations and Chief Financial Officer of Conceptus, a manufacturer of contraceptive medical devices. From January 1991 to February 1994, he served as Vice President of Finance and Administration and Chief Financial Officer at SanDisk, a manufacturer of flash memory products. Mr. Fitch currently serves on the board of directors of IRIDEX, a publicly-traded manufacturer of medical laser systems. Mr. Fitch holds a B.S. in Chemistry and an M.B.A. from Stanford University. Our Nominating and Corporate Governance Committee finds Mr. Fitch’s financial background to be extremely helpful to the Board and suited to his role as Chairperson of our Audit Committee. Mr. Fitch brings to us previous experience as a Chief Financial Officer for multiple companies over his long career, and as audit committee chairperson of a public company, which uniquely qualify him to serve as our Audit Committee Chairperson. In addition to his leadership and management skills, Mr. Fitch has considerable financial, auditing, risk management and corporate governance experience and he is an audit committee financial expert under the SEC’s rules, all of which enable him to make valuable contributions to the Board and the Audit Committee.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE FOR THE ELECTION OF EACH NOMINEE NAMED ABOVE.

Directors Continuing in Office Until the 2012 Annual Meeting of Stockholders

Edward L. Cahill, age 57, has served as a member of our Board since January 1999. Mr. Cahill has served as Managing Partner of HLM Venture Partners, a venture capital firm that invests primarily in emerging companies focused on health care information technology, health care services and medical technology, since May 2000. From June 1995 to May 2000, Mr. Cahill served as a founding partner of Cahill, Warnock & Company (now Camden Partners), a Baltimore venture capital firm. Previously, Mr. Cahill was a Managing Director of Alex, Brown & Sons, an investment services brokerage, where he headed the firm’s health care group from January 1986 through March 1995. Mr. Cahill is also a director of several private health care companies and serves as a trustee of Johns Hopkins Medicine, Johns Hopkins Health System and Mercy Health Services. Mr. Cahill holds an A.B. in American Civilization from Williams College and a Master of Public and Private Management degree from Yale University. Our Nominating and Corporate Governance Committee believes Mr. Cahill’s diverse and extensive board of directors and management experience, which has included public and private companies in the life sciences industry, provides him with key skills in working with directors, understanding board process and functions and working with financial statements. He brings to our Board the perspective of an experienced long-term investor in numerous biotechnology companies, as well as a strong financial management background, all of which qualify him for our Audit Committee and our Nominating and Corporate Governance Committee. In addition, Mr. Cahill has extensive experience with mergers and acquisitions.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

General

This section describes key corporate governance guidelines and practices that we have adopted. Complete copies of our Corporate Governance Guidelines, the charters of the committees of our Board of Directors and our Code of Business Conduct and Ethics described below may be viewed on our Internet website at http://ir.masimo.com under “Corporate Governance.” Alternately, you can request a copy of any of these documents free of charge by writing to our Corporate Secretary, c/o Masimo Corporation, 40 Parker, Irvine, California 92618.

Corporate Governance Guidelines

Our Board of Directors has adopted corporate governance guidelines to assist the Board in the exercise of its duties and responsibilities and to serve the best interests of Masimo and our stockholders. These guidelines, which provide a framework for the conduct of the Board’s business, provide that:

•

except with respect to matters reserved to our stockholders, our Board of Directors, which selects our senior management team, is our ultimate decision-making body;

•

the primary responsibilities of our Board are oversight, counseling and direction to management of Masimo for the benefit of Masimo and our stockholders;

•

it is our policy that except in unusual circumstances, the positions of the Chairman of our Board and our Chief Executive Officer be held by the same person;

•

a majority of the members of our Board shall be independent directors;

•

ordinarily, directors should not serve on more than four boards of publicly-traded companies, including our Board;

•

our Board and our Board committees have full and free access to management and, as necessary and appropriate, independent advisors;

•

the independent directors meet regularly in executive session;

•

on an annual basis, our Board and each of its committees will conduct a self-evaluation to determine whether they are functioning effectively; and

•

members of our Board shall regularly review developments in the areas of corporate governance and board service, hold periodic meetings with key members of our management and, as deemed appropriate, make visits to our key facilities.

Independence of the Board of Directors

Our Board has the responsibility for establishing corporate policies and for the overall performance of the Company, although it is not involved in day-to-day operations. As required under the marketplace rules of the Nasdaq Stock Market, LLC (“Nasdaq”), a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by our Board. Our Board consults with our 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 applicable Nasdaq rules, as in effect from time to time. Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his family members, and Masimo, our senior management and our independent auditors, our Board has determined that all of our directors other than Mr. Kiani are independent, as defined in Nasdaq Listing Rule 5605(a)(2).

Board Leadership Structure

Our Board believes that our Chief Executive Officer is best situated to serve as Chairman because he is the director that is most familiar with our business and industry, possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing us and is therefore best positioned to develop agendas that ensure that the Board’s time and attention are focused on the most critical matters. Our independent directors bring experience, oversight and expertise from outside the company and industry, while the Chief Executive Officer brings company-specific experience and expertise. The Board believes that the combined role of Chairman and Chief Executive Officer facilitates information flow between management and the Board, which are essential to effective governance.

Board’s Role in Risk Oversight

Our Board has an active role, as a whole and also at the committee level, in overseeing management of our risks. The Board regularly reviews information regarding our credit, liquidity and operations, as well as the risks associated with each. Our Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements. Our Audit Committee oversees management of financial risks. Our Nominating and Corporate Governance Committee manages risks associated with the independence of the Board of Directors and potential conflicts of interest and oversees management of risks associated with environmental, health and safety concerns. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, our entire Board of Directors is informed about such risks by the committees.

Information Regarding the Board of Directors

We are committed to maintaining the highest standards of business conduct and ethics. Our Board has adopted Corporate Governance Guidelines to assure that our Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices our Board will follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning and board committees and compensation. Our Board adopted the Corporate Governance Guidelines to, among other things, reflect changes to the Nasdaq listing standards and SEC rules adopted to implement provisions of the Sarbanes-Oxley Act of 2002. Our Corporate Governance Guidelines may be viewed on our Internet website at

http://ir.masimo.com under “Corporate Governance.”

Meetings

Our Board meets on a regular basis throughout the year to review significant developments affecting the Company and to act upon matters requiring its approval. Our Board also holds special meetings as required from time to time when important matters arise requiring Board action between scheduled meetings. During 2010, our Board of Directors met ten times and acted by unanimous written consent one time. None of our directors attended fewer than 75% of the total number of meetings of the Board of Directors held during 2010.

Executive Sessions

As required under applicable Nasdaq listing standards, our independent directors periodically meet in executive session at which only they are present.

Policy Regarding Board Member Attendance at Annual Meetings

It is the policy of our Board to invite directors and nominees for director to attend annual meetings of our stockholders. We held one annual meeting of stockholders in 2010. Mr. Kiani was the only member of our Board who attended the meeting.

Information Regarding Board Committees

Our Board has established standing Audit, Compensation and Nominating and Corporate Governance Committees to devote attention to specific subjects and to assist it in the discharge of its responsibilities. All three committees operate under a written charter adopted by our Board of Directors, each of which is available on our Internet website at http://ir.masimo.com under “Corporate Governance.” The following table provides membership and meeting information for fiscal year 2010 for each of the Board committees. Each director attended at least 75% of the meetings of the committees of Board on which he served, held during the period for which he was a committee member.

Below is a description of each committee of our Board of Directors. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board of Directors 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 Masimo.

Audit Committee

We have a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Our Audit Committee is comprised of Mr. Cahill, Dr. Coleman and Mr. Fitch. Mr. Fitch serves as the Chairperson of the Audit Committee. The functions of this Committee include, among others:

•

evaluating our independent registered public accountant’s qualifications, independence and performance;

•

determining the engagement of our independent auditors;

•

approving the retention of our independent auditors to perform any proposed audit and permissible non-audit services;

•

monitoring the rotation of partners of our independent auditors on our engagement terms as required by law;

•

reviewing our financial statements;

•

reviewing our critical accounting policies and estimates;

•

discussing with our management and our independent auditors the results of the annual audit and the review of our quarterly financial statements; and

•

reviewing and evaluating, at least annually, the performance of the Audit Committee and its members, including compliance of the Audit Committee with its charter.

Typically, the Audit Committee meets at least quarterly and with greater frequency if necessary. Our Board has adopted a written charter of the Audit Committee that is available to stockholders on our Internet website at http://ir.masimo.com under “Corporate Governance.”

Under the applicable rules and regulations of Nasdaq, each member of a company’s audit committee must be considered independent in accordance with Nasdaq Listing Rule 5605(c)(2)(A)(i) and (ii) and Rule 10A-3(b)(1) under the Exchange Act. Our Board reviews the Nasdaq Listing Rule standards and Exchange Act definitions of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Nasdaq Listing Rule 5605(c)(2)(A)(i) and (ii)). Our Board has determined that all members of our Audit Committee also meet the requirements for financial literacy under the Nasdaq Listing Rules.

Our Board has determined that Mr. Fitch, the Chairperson of our Audit Committee, is an audit committee financial expert, as defined under applicable SEC rules, and that Mr. Fitch meets the background and financial sophistication requirements under Nasdaq Listing Rule 5605(c)(2)(A). In making this determination, the Board made a qualitative assessment of Mr. Fitch’s level of knowledge and experience based on a number of factors, including his formal education and experience. Both our independent registered public accounting firm and internal financial personnel regularly meet privately with our Audit Committee and have unrestricted access to this committee.

AUDIT COMMITTEE REPORT

Our Audit Committee is composed of “independent” directors, as determined in accordance with Nasdaq Listing Rule 5605(a)(2) and Rule 10A-3 of the Exchange Act. The Audit Committee operates pursuant to a written charter adopted by the Board, a copy of which may be viewed on our Internet website at http://ir.masimo.com under “Corporate Governance.”

As described more fully in its charter, the purpose of the Audit Committee is to assist our Board with its oversight responsibilities regarding the integrity of our financial statements, our compliance with legal and regulatory requirements, assessing the independent registered public accounting firm’s qualifications and independence and the performance of the persons performing internal audit duties for us and the independent registered public accounting firm. Management is responsible for the preparation, presentation and integrity of our financial statements as well as our financial reporting process, accounting policies, internal audit function, internal accounting controls and disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The following is the Audit Committee’s report submitted to the Board for 2010.

The Audit Committee has:

•

reviewed and discussed our audited financial statements with management and Grant Thornton LLP, the independent registered public accounting firm;

•

discussed with Grant Thornton LLP the matters required to be discussed by Statement on Auditing Standards No. 114 (AICPA, Professional Standards, Vol. 1, AU Section 380), Communications with Audit Committees, as may be modified or supplemented; and

•

received from Grant Thornton LLP the written disclosures and the letter regarding their communications with the Audit Committee concerning independence as required by the Public Company Accounting Oversight Board and discussed the auditors’ independence with them.

In addition, the Audit Committee has met separately with management and with Grant Thornton LLP.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year ended January 1, 2011 for filing with the Securities and Exchange Commission. The Audit Committee also has selected and engaged Grant Thornton LLP as Masimo’s independent auditors for the fiscal year ending December 31, 2011, and is seeking ratification of the selection by Masimo’s stockholders.

Audit Committee

Mr. Edward L. Cahill

Dr. Robert Coleman

Mr. Sanford Fitch

This foregoing audit committee report is not “soliciting material,” is not deemed “filed” with the SEC, and shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing of ours under the Securities Act of 1933, as amended, or under the Exchange Act, except to the extent we specifically incorporate this report by reference.

Compensation Committee

Our Compensation Committee is comprised of Drs. Barker and Coleman and Mr. Lasersohn. Dr. Coleman serves as the Chairperson of our Compensation Committee. The functions of this committee include, among others:

•

determining the compensation and other terms of employment of our executive officers and reviewing and approving corporate performance goals and objectives relevant to such compensation;

•

evaluating and recommending the type and amount of compensation to be paid or awarded to our Board members;

•

evaluating and recommending to our Board the equity incentive plans, compensation plans and similar programs advisable for us, as well as modification or termination of existing plans and programs;

•

administering our equity incentive plans;

•

establishing policies with respect to equity compensation arrangements;

•

reviewing and approving the terms of any employment agreements, severance arrangements, change in control protections and any other compensatory arrangements for our executive officers; and

•

reviewing and evaluating, at least annually, the performance of the Compensation Committee and its members, including compliance of the Compensation Committee with its charter.

Our Board has adopted a written charter of the Compensation Committee that is available to stockholders on our Internet website at http://ir.masimo.com under “Corporate Governance.” Our Board has determined that all members of our Compensation Committee are independent (as independence is currently defined in Nasdaq Listing Rule 5605(a)(2)). The Compensation Committee meets from time to time during the year. The agenda for each meeting is usually developed by the Chairperson of the Compensation Committee, in consultation with our Chief Executive Officer and other representatives of senior management and human resources as necessary. The Chief Executive Officer may not participate in or be present during any deliberations or determinations of the Compensation Committee regarding his compensation. The charter of the Compensation Committee grants the Compensation Committee full access to all of our books, records, facilities and personnel, as well as authority to obtain, at our expense, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms.

To assist management and the Compensation Committee in assessing and determining competitive compensation packages, we engaged Compensation Strategies, Inc., an independent compensation consultant, in May 2007 and January 2010. In May 2007, the Compensation Committee requested that Compensation Strategies, Inc. match our compensation practices for our Chief Executive Officer and our Chief Financial Officer to those described in public sources for a group of peer companies in the medical device/diagnostic monitoring equipment industry, and that Compensation Strategies, Inc. use public and private survey data for all other executive officer positions and as a supplement to the data filed publicly by this peer group of companies. In January 2010, the Compensation Committee requested that Compensation Strategies, Inc. conduct a competitive review of executive compensation for our executive officers. Compensation Strategies, Inc. is independent from Masimo, has not provided any services to Masimo other than preparing the two reports referenced above, and receives compensation from Masimo only for services provided to the Compensation Committee.

The Compensation Committee meets outside the presence of all of our executive officers, including the named executive officers, in order to consider appropriate compensation for our Chief Executive Officer. For all other named executive officers, the Compensation Committee meets outside the presence of all executive officers

except our Chief Executive Officer. The annual performance reviews of our executive officers are considered by the Compensation Committee when making decisions on setting base salary, targets for and payments under our bonus plan and grants of equity incentive awards. When making decisions on executive officers, the Compensation Committee considers the importance of the position to us, the past salary history of the executive officer and the contributions we expect the executive officer to make to the success of our business.

The specific determinations of the Compensation Committee with respect to executive compensation for fiscal year 2010 are described in greater detail in the “Compensation Discussion and Analysis” section of this Proxy Statement.

Compensation Committee Interlocks and Insider Participation

In 2010, our Compensation Committee consisted of Drs. Barker and Coleman and Mr. Lasersohn. No member of our Compensation Committee is currently or has been at any time one of our officers or employees, is or was a participant in a “related party” transaction under Item 404 of Regulation S-K promulgated by the SEC (“Regulation S-K”) in 2010, or has served as a member of the board of directors, board of trustees or compensation committee of any entity that has one or more officers serving as a member of our Board or our Compensation Committee. None of our executive officers serves or in the past has served as a member of the board of directors or compensation committee of any entity that has one or more of its executive officers serving on our Board of Directors or our Compensation Committee. Prior to establishing the Compensation Committee, our full Board made decisions relating to compensation of our executive officers.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K of the SEC’s rules and regulations with management and, based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated into our Annual Report on Form 10-K for the fiscal year ended January 1, 2011.

Consideration of Director Nominees

Director Qualifications

There are no specific minimum qualifications that the Board requires to be met by a director nominee recommended for a position on our Board, nor are there any specific qualities or skills that are necessary for one or more members of our Board to possess, other than as are necessary to meet the requirements of the rules and regulations applicable to us. The Nominating and Corporate Governance Committee considers a potential director candidate’s experience, areas of expertise and other factors relative to the overall composition of our Board and its committees, including the following characteristics:

•

the highest ethical standards and integrity and a strong personal reputation;

•

a background that provides experience and achievement in business, finance, biotechnology or other activities relevant to our business and activities;

•

a willingness to act on and be accountable for Board and, as applicable, committee decisions;

•

an ability to provide wise, informed and thoughtful counsel to management on a range of issues affecting us and our stockholders;

•

an ability to work effectively and collegially with other individuals;

•

loyalty and commitment to driving our success and increasing long-term value for our stockholders;

•

sufficient time to devote to Board and, as applicable, committee membership and matters; and

•

the independence requirements imposed by the SEC and Nasdaq.

The Nominating and Corporate Governance Committee retains the right to modify these criteria from time to time.

Security Holder Nominations

The Nominating and Corporate Governance Committee will consider director candidates recommended by our stockholders of record. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the criteria set forth above, based on whether a candidate was recommended by a stockholder of record or not. Stockholders of record who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at an annual meeting of stockholders must do so by delivering a written recommendation to the Nominating and Corporate Governance Committee, c/o Masimo Corporation, 40 Parker, Irvine, California 92618, Attn: Corporate Secretary, no later than the close of business on the 45th day nor earlier than the 75th day

prior to the anniversary date of the initial mailing of our proxy statement for our preceding year’s annual meeting of stockholders unless the meeting date is more than 30 days before or after the one-year anniversary of the preceding year’s annual meeting of stockholders, in which case the written recommendation must be received by our Corporate Secretary by no later than the close of business on the later of (i) the 90th day before the next annual meeting of stockholders or (ii) the 10th day following the day on which we first publicly announce the date of the next annual meeting of stockholders. Each written recommendation must set forth, among other information:

•

the name and address of the stockholder of record and any beneficial owner on whose behalf the nomination is being made;

•

the class, series and number of shares of Masimo, and any convertible securities of Masimo, that are beneficially owned by the stockholder of record and any beneficial owner on whose behalf the nomination is being made;

•

any proxy, contract, arrangement, understanding or relationship pursuant to which the stockholder of record and any beneficial owner on whose behalf the nomination is being made has the right to vote any of Masimo’s voting securities;

•

any “short” interest in Masimo’s securities held by the stockholder of record and any beneficial owner on whose behalf the nomination is being made;

•

the proposed director candidate’s name, age, business address and residential address;

•

complete biographical information for the proposed director candidate, including the proposed director candidate’s principal occupation or employment and business experience for at least the previous five years;

•

the class and number of shares of Masimo that are beneficially owned by the proposed director candidate as of the date of the written recommendation; and

•

any other information relating to the proposed director candidate that is required to be disclosed in solicitations for proxies for election of directors pursuant to Regulation 14A promulgated under the Exchange Act.

Director candidate nominations from stockholders must be provided in writing and must include the written consent of each proposed nominee to serve as director if so elected.

If a proposed director candidate is recommended by a security holder in accordance with the procedural requirements discussed above, the Corporate Secretary will provide the foregoing information to the Nominating and Corporate Governance Committee.

Evaluating Nominees for Director

Our Nominating and Corporate Governance Committee considers director candidates that are suggested by members of the committee, other members of our Board, members of management, advisors and our security holders who submit recommendations in accordance with the requirements set forth above. The Nominating and Corporate Governance Committee may, in the future, also retain a third-party search firm to identify candidates on terms and conditions acceptable to the Nominating and Corporate Governance Committee, but to date it 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 evaluates all nominees for director under the same approach whether they are recommended by security holders or other sources.

The Nominating and Corporate Governance Committee reviews candidates for director nominees in the context of the current composition of our Board and committees, the operating requirements of the Company and the long-term interests of our stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers the director nominee’s qualifications, diversity, age, skills and such other

factors as it deems appropriate given the current needs of the Board, the committees and Masimo, to maintain a balance of knowledge, experience, diversity and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews such directors’ overall service to the Board, the committees and Masimo during their term, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee will also determine whether the nominee must be independent for Nasdaq purposes, which determination will be based upon applicable Nasdaq listing standards and applicable SEC rules and regulations. Although we do not have a formal diversity policy, when considering diversity in evaluating director nominees, the Nominating and Corporate Governance Committee focuses on whether the nominees can contribute varied perspectives, skills, experiences and expertise to the Board.

The Nominating and Corporate Governance Committee will evaluate the proposed director’s candidacy, including proposed candidates recommended by security holders, and recommend whether the Board should nominate the proposed director candidate for election by our stockholders.

Stockholder Communications with the Board of Directors

Our Board has adopted a formal process by which security holders may communicate with the Board or any of its directors. Stockholders of Masimo wishing to communicate with our Board or an individual director may send a written communication to the Board or such director, c/o Masimo Corporation, 40 Parker, Irvine, California 92618, Attn: Corporate Secretary. Each communication must set forth:

•

the name and address of the Masimo security holder(s) on whose behalf the communication is sent; and

•

the number of Masimo shares that are owned beneficially by the security holder(s) as of the date of the communication.

Each communication will be reviewed by Masimo’s Corporate Secretary to determine whether it is appropriate for presentation to the Board or the individual director. Examples of inappropriate communications include junk mail, spam, mass mailings, product complaints, product inquiries, new product suggestions, resumes, job inquiries, surveys, business solicitations and advertisements, as well as unduly hostile, threatening, illegal, unsuitable, frivolous, patently offensive or otherwise inappropriate material. These screening procedures have been approved by a majority of the independent members of our Board.

Communications determined by our Corporate Secretary to be appropriate for presentation to the Board or such director will be submitted to the Board or the individual director on a periodic basis. All communications directed to the Audit Committee in accordance with our Code of Business Conduct and Ethics or our Open Door Policy for Reporting Complaints Regarding Accounting, Auditing and Other Matters that relate to questionable accounting or auditing matters involving the Company (the “Open Door Policy”) will generally be forwarded to a compliance officer designated by the Audit Committee to receive and review these communications and then promptly and directly forwarded by a compliance officer to the Audit Committee as appropriate in accordance with the terms of the Code of Business Conduct and Ethics and the Open Door Policy.

Code of Business Conduct and Ethics

We have adopted the Masimo Corporation Code of Business Conduct and Ethics that applies to all of our employees, executive officers and directors. The Code of Business Conduct and Ethics is available to stockholders on our Internet website at http://ir.masimo.com under “Corporate Governance.” If we make any substantive amendments to our Code of Business Conduct and Ethics or grant any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our Internet website at http://ir.masimo.com under “Corporate Governance” and/or in our public filings with the SEC.

COMPENSATION OF EXECUTIVE OFFICERS

Compensation Discussion and Analysis

The following compensation discussion and analysis contains statements regarding future individual and company performance targets and goals. These targets and goals are disclosed in the limited context of Masimo’s compensation programs and should not be understood to be statements of management’s expectations or estimates of results or other guidance. Masimo specifically cautions investors not to apply these statements to other contexts.

Overview—Compensation Objectives

The primary objectives of the Compensation Committee of our Board with respect to executive compensation are to attract, retain and motivate the best possible executive talent. The focus is to tie short and long-term cash and equity incentives to the achievement of measurable corporate objectives and to align executives’ incentives with stockholder value creation. To achieve these objectives, the Compensation Committee has adopted a compensation approach that ties a substantial portion of executives’ overall compensation to our operational performance. In addition, we evaluate and reward our executive officers based on their willingness to take a leadership position in improving our internal structures and processes and their ability to identify and exploit opportunities to grow our business.

We must match market cash compensation levels and satisfy the day-to-day financial requirements of our candidates through competitive base salaries and cash bonuses. We also compete for key personnel on (i) the basis of our vision of future success, (ii) our culture and company values, (iii) the cohesiveness and productivity of our teams, and (iv) the excellence of our technical and management personnel. In all of these areas, we compete with other medical device and biotechnology companies, where there is significant competition for talented employees. We believe that we must provide competitive compensation packages to attract and retain executive officers and to help our executive management function as a stable team over the longer term. We believe that we must compete for executive and key technical talent in this highly competitive market in Southern California. We also believe that for certain executive level positions, we compete against other successful public and private companies in Southern California for talent. Accordingly, our compensation philosophy has been to maintain an aggressive pay posture for total compensation, as well as components of total compensation. In addition, with the same competitive pay issues to consider, our Compensation Committee has developed incentive bonus and equity plans designed to align stockholder and employee interests.

We have adopted an approach to compensation comprised of a mix of short- and long-term components, cash and equity elements in the proportions we believe will provide the proper incentives, reward our senior management team and help us achieve the following goals:

•

align our executive officers’ compensation with our business objectives and the interests of our stockholders;

•

foster a goal-oriented, highly motivated management team whose participants have a clear understanding of business objectives and shared corporate values;

•

control costs in each facet of our business to maximize our efficiency; and

•

enable us to attract, retain and motivate a world class leadership team.

The compensation of our executive officers is based in part on the terms of employment agreements and offer letters we entered into with each of our executive officers, which set forth the initial base salaries and initial option grants for our executive officers, as well as the terms of our cash bonus plans. See “—Employment Agreement and Offer Letters” and “—Cash Bonus Plans” below.

In 2010, we believe that our compensation offering for executive officer talent of base salary, bonus plan and equity grant provided a competitive compensation package to attract, retain and motivate world class talent. The Compensation Committee generally undertakes the annual merit review process for purposes of determining executive officer salaries at the beginning of each fiscal year. The most recent merit increase in executive officer salaries occurred in January 2010. The establishment of two financial targets as our 2010 company goal under our Executive Annual Cash Bonus Plan (the “Executive Annual Plan”) reinforced two other compensation plan goals; namely, the alignment of our executive officers’ compensation with our business objectives and the interests of our stockholders as well as the fostering of a goal-oriented, highly motivated management team whose participants have a clear understanding of business objectives and shared corporate values. For 2010, the individual factor under the Executive Annual Plan for our Chief Executive Officer was based on the Compensation Committee’s evaluation of the our Chief Executive Officer’s performance in guiding Masimo through a continued difficult economic environment and in achieving a variety of internal goals related to product quality, delivery of the Halo Index, which is a dynamic new indicator that facilitates continuous global trending and assessment of multiple physiological measurements to quantify changes in patient status, and other operationally oriented goals. The individual performance factor for 2010 determined by our Chief Executive Officer for the other named executive officers focused on their own individual attainment of functionally specific goals and objectives set at the beginning of the year. In addition, in March 2011, we paid bonuses to our executive officers under our Executive Multi-Year Cash Bonus Plan (the “Executive Multi-Year Plan”) for the first three-year plan period, from 2008 through 2010. The bonus was based on the Compensation Committee’s assessment of our performance against product revenue and earnings per share goals during the three-year period. These goals were higher than the goals used to measure annual performance under our Executive Annual Plan. The Executive Multi-Year Plan was adopted in 2007 to provide our executive officers with additional incentives to deliver exceptional financial and operational results over a three-year period.

Role of Our Compensation Committee

Our Compensation Committee approves, administers and interprets our executive compensation and benefit policies. Our Compensation Committee was appointed by our Board and consists entirely of directors who are “outside directors” for purposes of Section 162(m) of the Internal Revenue Code, as amended (the “Code”), and “non-employee directors” for purposes of Rule 16b-3 under the Exchange Act. Our Compensation Committee is comprised of Drs. Barker and Coleman and Mr. Lasersohn. Dr. Coleman is our Compensation Committee chairperson.

The Compensation Committee considers recommendations from Joe Kiani, our Chief Executive Officer, in determining executive compensation. While Mr. Kiani discusses his recommendations with the Compensation Committee, he does not participate in determining his own compensation. In making his recommendations, Mr. Kiani receives input from our Human Resources department and has access to various third-party compensation surveys and compensation data of publicly-traded companies we obtained from publicly-available SEC filings. With respect to the assessment of base salaries in January 2010, Mr. Kiani also had competitive compensation information contained in a third party report authorized by our Compensation Committee. The report prepared in January 2010 included market information based on a peer group of companies and constructed median pay levels reflective of a company with $400 million in annual revenues, which the Compensation Committee believed to be an appropriate benchmark in light of our size and expected growth at the time it authorized the report. None of our other executive officers participates in the Compensation Committee’s discussions regarding executive compensation. The Compensation Committee does not delegate any of its functions to others in determining executive compensation.

Our Compensation Committee has taken the following steps to ensure that our approach to executive compensation and benefits is consistent with both our compensation philosophy and our corporate governance guidelines:

•

evaluated our compensation practices and assisted in developing and implementing the executive compensation philosophy;

•

developed recommendations with regard to executive compensation structures that were reviewed and approved by our Compensation Committee and Board;

•

established a practice of prospectively reviewing the performance and determining the compensation earned, paid or awarded to our Chief Executive Officer; and

•

established a policy to review on an annual basis the performance of our other executive officers with assistance from our Chief Executive Officer and determining what we believe to be appropriate total compensation.

Components of our Compensation Approach

Our compensation approach is comprised of five components:

•

base salary;

•

annual and multi-year cash bonuses;

•

equity-based incentives;

•

other benefits; and

•

severance and termination protection.

We chose to build our executive compensation approach around these elements because we believe that together they have been and will continue to be effective in achieving our overall objectives. We utilize short-term compensation, including base salary and annual cash bonuses, to motivate and reward our key executives. The use and weight of each compensation element is based on a subjective determination by the Compensation Committee of the importance of each element in meeting our overall objectives. We believe that, in addition to base salaries and bonuses, stock option awards are the primary compensation-related motivator in attracting and retaining qualified employees.

Base Salary. Base salary is used to provide each named executive officer a set amount of money during the year with the expectation that he will perform his responsibilities to the best of his ability and in the best interests of Masimo. Base salaries will typically be used to recognize the experience, skills, knowledge and responsibilities required of each executive officer, as well as competitive market conditions. The base salaries of our named executive officers are typically reviewed every one to two years. Prior to 2009, executive salaries were typically adjusted annually, effective June 1st of each year. However, in 2009, based on then-current global economic conditions and a desire to better synchronize the year end management bonus assessment with the annual merit review process, the Compensation Committee determined to delay the annual salary review process from June 1, 2009 to January 1, 2010, at which time our executive officers received a slight increase in their base salaries. In 2011, the Compensation Committee, consistent with the Company’s annual financial plan objectives and the uncertainty surrounding the timing and terms of the resolution of our negotiations with Covidien regarding the parties’ royalty agreement, decided to defer its decision on whether to modify salaries for executive officers in 2011 until July 2011. In 2008, our Compensation Committee conducted a competitive assessment of our current compensation levels for all employees to determine if our compensation levels remained at targeted levels and our pay practices were appropriate. Salaries were evaluated against industry specific and general published survey compensation data. Specifically, our Compensation Committee considered the information provided through our paid subscription with Salary.com, which purports to provide “up-to-date” market compensation information as part of a continual research study. The data obtained from Salary.com purported to show salary ranges and distributions for all employees, including officers, holding comparable positions at companies of similar size, geographic location and market focus. The data from Salary.com did not name the companies from which the market data was obtained. In addition, our Compensation Committee considered market data from the Economic Research Institute, the Employers Group, which provides data regarding California payroll practices. The Compensation Committee also factored in estimated cost of living changes

during the prior year according to data provided by the Bureau of Labor Statistics. Based on its analysis, the Compensation Committee determined to increase salaries for all employees, including officers, by 4% as a baseline percentage increase.

Additionally in 2008, for our executive officers, the Compensation Committee used market data provided by Compensation Strategies, Inc. and further considered the individual performance of our executive officers for the prior year to determine whether to modify the baseline 4% increase (upward or downward) for the executive officer, based on the following qualitative factors: leadership, initiative, relationship and team building, business sense, communication, vision and perspective, supervision, organizational savvy, ethical practices, fiscal responsibility, and length of service with the company. No single criterion was weighted more heavily than any other in this evaluation, as the Compensation Committee evaluated the executive’s overall performance and contributions to our company in determining salary adjustments in 2008. In addition, the Compensation Committee considered the Chief Executive Officer’s recommendations with respect to the other named executive officers. Based on this analysis, salaries for our executed officers were adjusted, effective June 1, 2008. These salaries continued in place through 2009.

In January 2010, we retained Compensation Strategies, Inc. to conduct a competitive assessment of our current compensation levels. The competitive market data presented in the compensation consultant’s study for our Chief Executive Officer and our Chief Financial Officer was obtained from the SEC filings of a peer group comprised of the following 18 publicly-traded companies in the medical device/diagnostic monitoring equipment industry: Abaxis, Inc.; AGA Medical Holdings, Inc.; AngioDynamics, Inc.; ArthroCare Corporation; Cardiac Science Corporation; Gen-Probe Incorporated; Haemonetics Corporation; ICU Medical, Inc.; Meridian Bioscience, Inc.; Merit Medical Systems, Inc.; Myriad Genetics, Inc; Natus Medical, Inc.; NuVasive, Inc.; Quidel Corporation; SonoSite, Inc.; Thoratec Corporation; Volcano Corporation; and ZOLL Medical Corporation. Public and private survey information was used for all other executive positions as a supplement to the proxy data. The market compensation data included median pay levels that were reflective of a company with annual revenues of $400 million, which the Compensation Committee believed to be the appropriate benchmark in light of our size and our expected growth at that time. Our Compensation Committee also considered the information provided through our paid subscription with Salary.com, which purports to provide “up-to-date” market compensation information as part of a continual research study. The data obtained from Salary.com purported to show salary ranges and distributions for all employees, including officers, holding comparable positions at companies of similar size, geographic location and market focus. The data from Salary.com did not name the companies from which the market data was obtained. In addition, our Compensation Committee considered market data from the Economic Research Institute, the Employers Group, which provides data regarding California payroll practices. Although our Compensation Committee references the data provided by third party sources to gain a general understanding of compensation levels, we do not engage in benchmarking against other companies’ compensation programs or practices to establish our compensation levels or make specific compensation decisions with respect to our executive officers or other employees. Based on this analysis, we determined that an approximately 3% baseline salary increase was appropriate for all positions other than sales. We further considered the individual performance of the named executive officers for 2009 to determine whether to modify the baseline 3% increase based on the following qualitative factors: leadership, initiative, relationship and team building, business sense, communication, vision and perspective, supervision, organizational savvy, ethical practices, fiscal responsibility, and length of service with Masimo. No single criterion was weighted more heavily than any other in this evaluation, as the Compensation Committee evaluated the executive’s overall performance for, contributions to and history with Masimo in determining salary adjustments. In addition, the Compensation Committee considered the Chief Executive Officer’s recommendations with respect to the other named executive officers.

The current base salaries for our named executive officers are as follows:


Name and Position(s)	Salary
Joe Kiani	$	706,992
Chief Executive Officer & Chairman
Mark P. de Raad		315,243
Executive Vice President, Chief Financial Officer & Corporate Secretary
Tony Allan		315,000
Chief Operating Officer
Rick Fishel		316,400
President, Worldwide OEM Business & Strategic Development
Yongsam Lee		310,344
Chief Information Officer & Executive Vice President, Regulatory Affairs

The salaries of Messrs. Kiani, de Raad, Fishel and Lee are the same base salaries approved by our Compensation Committee, effective January 1, 2010. The salary increases in January 2010 of Messrs. Kiani, de Raad, Fishel and Lee reflected a 2.0%-3.0% increase over their salaries for the period from June 1, 2008 through December 31, 2009, which is the same increase provided to our employees generally. None of these salaries has changed since they became effective on January 1, 2010.

Mr. Allan’s annual salary was determined in May 2011, and was established through negotiations between us and Mr. Allan immediately prior to the time he joined Masimo. In setting Mr. Allan’s base salary, the Compensation Committee took into account Mr. Allan’s level of experience, the complexity of the role for which Mr. Allan was hired, Mr. Allan’s base salary and overall compensation at his previous employer and other factors. Mr. Allan’s salary has not changed since he commenced his employment with us.

Cash Bonuses. Our Compensation Committee approves the annual cash bonuses for all executive officers. These bonuses, if earned, are paid after the end of the calendar year. We paid two sets of bonuses to executive officers in 2011. The first set of bonuses was paid on March 15, 2011 pursuant to our Executive Annual Plan for our fiscal year 2010. The second set of bonuses was paid on March 15, 2011 pursuant to our Executive Multi-Year Plan for our plan period fiscal year 2008 through fiscal 2010. We have not paid any significant signing or promotion bonuses to our executive officers, nor have we guaranteed any future bonuses to our executive officers.

Annual Cash Bonuses.

Bonuses paid to our named executive officers for 2010 were governed by our Executive Annual Plan, which became effective on January 1, 2007, and was most recently amended on September 15, 2008. The Executive Annual Plan also covers bonuses payable to our other executive officers and certain other exempt employees. To be eligible for a bonus under the plan for any plan year, the participant must be employed with us for at least six months and one day during the plan year. Pursuant to the terms of the Executive Annual Plan, the bonus award for each named executive officer was calculated based upon the product of (A) the named executive officer’s base salary as of the end of the immediately preceding fiscal year, multiplied by (B) (i) the target bonus percentage factor assigned to the job classification level of the named executive officer, multiplied by (ii) the company percentage factor assigned by the Compensation Committee based upon Masimo’s level of achievement of the immediately preceding fiscal year’s financial and other non-financial targets multiplied by (iii) the named executive officer’s individual percentage factor assigned by our Chief Executive Officer for the other named executive officers and, in the case of our Chief Executive Officer, assigned by our Compensation Committee. Under the Executive Annual Plan, our Compensation Committee has the authority to substitute a maximum bonus percentage for some or all plan participants in lieu of the target bonus percentage for the plan year. The Compensation Committee also has the authority to allow the Chief Executive Officer to determine, based on his own subjective analysis, whether the company percentage factor as approved by the Compensation Committee should be lowered, but he does not have the authority to increase the company percentage factor above the amount approved by the Compensation Committee.

Company Factor. Under the Executive Annual Plan, in the event the Compensation Committee determined that we (i) did not achieve 100% of the financial and other non-financial targets for 2010, it had the discretion to set the company percentage factor at below 100%, including zero; (ii) achieved 100% or more of the 2010 financial and other non-financial targets, the company percentage factor would automatically be set at 100%; and (iii) achieved more than 100% of the 2010 financial and other non-financial targets, it had the discretion to set the company percentage factor at or above 100%. For 2010, our corporate objectives focused upon achieving two financial targets: (a) aggregate product revenues of at least $345 million, and (b) GAAP earnings per share of at least $1.12 per share. In addition, each employee, including each executive officer, had other individual objectives for the year which were designed to contribute to the achievement of our corporate objectives. In setting the objectives for the annual cash bonuses, our Compensation Committee believed that the 2010 corporate financial targets were achievable, but not easily attainable, provided that there was a maximum and sustained effort from each level of our organization. In 2010, with total product revenues of $356.4 million, the Compensation Committee determined that we met the product revenue goal and that, with earnings per share of $1.21, we also met the 2010 earnings per share goal. Despite achieving 100% of the financial targets, based on a subjective assessment of the overall level of achievement of a variety of other non-financial goals associated with product quality, new product introductions and other internal operational metrics, including volumes of shipments of monitors and sensors, the Compensation Committee approved a 90% company factor contribution. However, also consistent with the terms of the Executive Annual Plan, the Chief Executive Officer had the ability to evaluate, based on his own subjective criteria, whether the full amount approved by the Compensation Committee should be lowered. Based on the Chief Executive’s own subjective assessment of the Company’s overall performance in 2010, the Chief Executive Officer determined that the 90% company factor was appropriate.

Individual Factor. Under the Executive Annual Plan, each named executive officer’s individual percentage factor can range from 0% to 100%. For all of our named executive officers other than our Chief Executive Officer, the individual percentage factor for 2010 was determined by our Chief Executive Officer based solely upon his subjective assessment of each other named executive officer’s performance of the job-related duties and responsibilities assigned to such named executive officer during 2010. For purposes of determining the individual factor of our Chief Executive Officer under the Executive Annual Plan, the Compensation Committee makes a subjective determination of our Chief Executive Officer’s overall performance during the applicable plan year, provided that in the event the Compensation Committee established the company percentage factor for any plan year at 100%, then our Chief Executive Officer’s individual factor is automatically set at 100%. For the reasons noted above, the company factor for 2010 was set at 90% by our Compensation Committee. Our Chief Executive Officer’s individual performance factor for 2010 under the Executive Annual Plan was set at 100% because the Compensation Committee determined that the Chief Executive Officer continued to demonstrate outstanding management performance in successfully guiding Masimo through a difficult economic environment, led Masimo in achieving a variety of non-financial goals associated with product quality, new product introductions, including the Halo Index, and other internal operational metrics, including the volume of shipments of monitors and sensors. The individual percentage factor for each of our other named executive officers for 2010 was set at various levels based on our Chief Executive Officer’s subjective determination of the level of achievement of individual, non-financial goals and the named executive officer’s overall management contribution during 2010.

Target Bonus Percentage. Under the Executive Annual Plan, the target bonus percentage is based on the job classification of our employees and other key employees. Our Chief Executive Officer is at the highest job classification, which corresponded to a target bonus percentage of 50% for the 2010 plan year, as determined by our Compensation Committee. The target bonus percentage of our other executive officers was set at 40% by our Compensation Committee. These percentages were set by our Compensation Committee when the Executive Annual Plan was adopted in 2007.

Maximum Bonus Percentage. The Executive Annual Plan permits our Compensation Committee, in its sole discretion, to substitute a maximum bonus percentage in lieu of a plan participant’s target bonus percentage.

Along with the target bonus percentage, the maximum bonus percentage is generally based upon a participant’s job classification level. For 2010, our Compensation Committee determined not to substitute a maximum bonus percentage for any named executive officer’s target bonus percentage under the Executive Annual Plan.

Using these amounts, the bonuses paid to our named executive officers under our Executive Annual Plan for 2010 were as follows:


Name and Position(s)	Bonus
Joe Kiani Chief Executive Officer & Chairman	$	318,146
Mark P. de Raad Executive Vice President, Chief Financial Officer & Corporate Secretary		107,813
Tony Allan Chief Operating Officer		64,032
Rick Fishel President, Worldwide OEM Business & Strategic Development		108,209
Yongsam Lee Chief Information Officer & Executive Vice President, Regulatory Affairs		100,551

The corporate level goals under the Executive Annual Plan for 2011 are initially established by the Chief Executive Officer and then reviewed and approved by our Compensation Committee annually during the first quarter of the year. Our Compensation Committee believes that the 2011 goals align well with our strategy of attaining sustainable growth. The specific targets under the plan are not disclosed because we believe disclosure of this information would cause us competitive harm. These targets are based on our confidential operating plan for the 2011 fiscal year and are intended to be realistic and reasonable, but challenging, in order to drive sustainable growth and performance of the company in 2011.

Multi-Year Cash Bonuses.

Our Compensation Committee adopted our Executive Multi-Year Cash Bonus Award Plan (the “Executive Multi-Year Plan”) to provide our executive officers with additional incentives to deliver exceptional financial and operational results in each three-year plan period. The Executive Multi-Year Plan became effective on January 1, 2008. We pay bonuses for a plan period under the Executive Multi-Year Plan only if the Executive Multi-Year Plan Administrator has approved written resolutions that either establish the terms and conditions relating to the payment of bonuses that will apply for the plan period, or otherwise approve the payment of bonuses. Each plan period is comprised of three consecutive calendar years. Our executives are eligible to receive a cash bonus at the end of an applicable three-year plan period based on our achievement of certain financial targets established by our Compensation Committee for the period as long as they have been employed with us for at least the last 18 months during the plan period. Pursuant to the terms of the Executive Multi-Year Plan, the bonus award for each named executive officer is calculated based upon the product of (A) three times the named executive officer’s average salary over the three-year plan period, multiplied by (B) (i) the multi-year performance bonus percentage factor assigned to the job classification level of the named executive officer, multiplied by (ii) the company percentage factor assigned by the Compensation Committee based upon the attainment of financial measures established by our Compensation Committee during the first three months of the plan period, multiplied by (iii) the named executive officer’s individual percentage factor assigned by the Chief Executive Officer for the other named executive officers and, in the case of our Chief Executive Officer, assigned by the Compensation Committee. Amounts payable under the Executive Multi-Year Plan are pro rated based on the number of full weeks during the plan period in which the participant is employed with us, subject to the 18-month employment requirement discussed above. The first plan period under the Executive Multi-Year Plan began on January 1, 2008 and ended on December 31, 2010. Mr. Allan was not an employee of ours for the final 18 months of the 2008 through 2010 plan period and therefore he was not eligible to receive a bonus under the Executive Multi-Year Plan for this period. The Compensation Committee has not approved the commencement of a new three-year plan period under the Executive Multi-Year Plan.

Performance Bonus Percentage Factor. Under the Executive Multi-Year Plan, the performance bonus percentage factor is based on the job classification of our employees and other key employees. Our Chief Executive Officer is at the highest job classification, which corresponded to a target bonus percentage of 50% for the 2008 through 2010 plan period, as determined by our Compensation Committee. The target bonus percentage of our other executive officers was set at 40% for the 2008 through 2010 plan period by our Compensation Committee. These percentages were set by our Compensation Committee when the Executive Multi-Year Plan was adopted in 2007.

Company Factor. Under the Executive Multi-Year Plan, in the event the Compensation Committee determined that we (i) did not achieve 100% of the company’s objectives and assessment criteria for the 2008 through 2010 plan period (the “2008-2010 Period Criteria”), it had the discretion to set the company percentage factor at below 100%, including zero; (ii) achieved 100% or more of the 2008-2010 Period Criteria, the company percentage factor would automatically be set at 100%; and (iii) achieved more than 100% of the 2008-2010 Period Criteria, it had the discretion to set the company percentage factor at or above 100%. The 2008-2010 Period Criteria were comprised of various product revenue and earnings per share targets. In setting the 2008-2010 Period Criteria, our Compensation Committee believed that the criteria were stretch targets above the annual management bonus plan targets and therefore, were not easily attainable. The 2008-2010 Period Criteria for product revenues were $258 million, $328 million and $420 million for the years ended 2008, 2009 and 2010, respectively. The 2008-2010 Period Criteria for earnings per share were $0.57, $0.79 and $1.15 for the years ended 2008, 2009 and 2010, respectively. The Company achieved of 100% of the company factor goals for 2008, 50% of the company factor goals for 2009 and none of the company factor goals for 2010. Although the Company had earnings per share of $1.21 for 2010, $0.18 of this amount related to one-time items and therefore our adjusted earnings per share for 2010 was $1.03 for purposes of this plan. As a result, the Compensation Committee approved a 50% company factor contribution for the 2008 through 2010 plan period as the average of the Company’s performance over the period. However, also consistent with the terms of the Executive Multi-Year Plan, the Chief Executive Officer had the ability to evaluate, based on his own subjective criteria, whether the full amount approved by the Compensation Committee should be lowered. Based on the Chief Executive’s own subjective assessment of the Company’s overall performance in 2008 through 2010, the Chief Executive Officer determined that the 50% company factor was appropriate.

Individual Factor. Under the Executive Multi-Year Plan, each named executive officer’s individual percentage factor can range from 0% to 100%. For all of our named executive officers other than our Chief Executive Officer, the individual percentage factor for the 2008 through 2010 plan period was determined by our Chief Executive Officer based solely upon his subjective assessment of each other named executive officer’s performance of the job-related duties and responsibilities assigned to such named executive officer during the period. For purposes of determining the individual factor of our Chief Executive Officer under the Executive Multi-Year Plan, the Compensation Committee makes a subjective determination of our Chief Executive Officer’s overall performance during the applicable plan period, provided that in the event the Compensation Committee established the company percentage factor for any plan period at 100%, then our Chief Executive Officer’s individual factor is automatically set at 100% for the period. For the reasons noted above, the company factor for the 2008 through 2010 plan period was set at 50% by our Compensation Committee. Based on a subjective assessment of the overall level of achievement during the 2008 through 2010 plan period, the Compensation Committee set our Chief Executive Officer’s individual performance factor for this period under the Executive Multi-Year Plan at 100%. The individual percentage factor for each of our other named executive officers for the 2008 through 2010 plan period also was set at 100% based on our Chief Executive Officer’s subjective determination of the level of achievement of individual, non-financial goals and the named executive’s overall management contribution during this period.

Using these amounts, the bonuses paid to our named executive officers under our Executive Multi-Year Plan for the plan period of 2008 through 2010 were as follows:

Equity-Based Incentives. Salaries and bonuses are intended to compensate our executive officers for short-term performance. We also have adopted an equity incentive approach intended to reward longer-term performance and to help align the interests of our executive officers with those of our stockholders. We believe that long-term performance is achieved through an ownership culture that rewards performance by our executive officers through the use of equity incentives. Our equity incentive plans have been established to provide our employees, including our executive officers, with incentives to help align those employees’ interests with the interests of our stockholders. These equity incentive plans have provided the principal method for our executive officers to acquire equity interests in Masimo.

The size and terms of the initial option grant made to each executive officer upon joining us are primarily based on competitive conditions applicable to the executive officer’s specific position and the executive officer’s skill-set and prior experience and are set forth in the executive officer’s offer letter from us. In addition, the Compensation Committee considers the number of options owned by other executives in comparable positions within Masimo.

Any subsequent equity awards we make to our executive officers will be driven by our sustained performance over time, our executive officers’ ability to impact our results that drive stockholder value, their level of responsibility within Masimo, their potential to fill roles of increasing responsibility, and competitive equity award levels for similar positions in comparable companies. Equity forms a key part of the overall compensation for each executive officer and is evaluated each year as part of the annual performance review process and incentive payout calculation.

The amount of equity awarded to each executive officer was based on the Compensation Committee’s subjective determination of what was appropriate to incent the executives. Each of these grants vests over a five-year period with 20% vesting on each anniversary of the grant date. Since our initial public offering in August 2007, all stock options have been granted with an exercise price equal to the “fair market value” of a share of our common stock on the grant date, which the Compensation Committee has set as the closing price our common stock, as reported on Nasdaq, on the grant date. All equity awards to our employees, including to executive officers and directors, have been granted and reflected in our consolidated financial statements, based upon the applicable accounting guidance, with the exercise price equal to the fair market value on the grant date.

In May 2007, our Compensation Committee adopted the CEO and Executive Officer Equity Award Compensation Policy (the “Equity Award Compensation Policy”), which provides for annual grants of stock options, upon achieving a predetermined criteria, to certain of our officers, including our named executive officers. The policy was amended effective January 4, 2008. For a description of the Policy, see “—CEO and Executive Officer Equity Award Compensation Policy” below. Based on the overall assessment of the Compensation Committee, the following option grants were made to our named executive officers in February 2010 and in February 2011:

Mr. Allan’s employment with Masimo began in May 2010 and therefore he was not eligible to receive an option grant under the Equity Award Compensation Policy in February 2011.

Our Board adopted our 2007 Stock Incentive Plan (the “2007 Plan”) in November 2006, which permits the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares and other stock-based awards. The 2007 Plan became effective on August 8, 2007 in connection with our initial public offering. No further equity awards will be made under our Third Amended and Restated 1996 Incentive Stock Option Nonqualified Stock Option and Restricted Stock Purchase Plan (the “1996 Plan”) or our 2004 Incentive Stock Option Nonqualified Stock Option and Restricted Stock Purchase Plan (the “2004 Plan”). However, any options outstanding under our 1996 Plan or our 2004 Plan will continue to be governed by their existing terms. In addition to our Equity Award Compensation Policy, the Compensation Committee intends to evaluate other stock option grant programs for executive officers to continue aligning the interests of these individuals with those of our stockholders. See “—Employee Benefit Plans—2007 Stock Incentive Plan” below.

Our Compensation Committee reviews its grant date practices for stock options to assure that our grant practices are aligned with what it believes constitute best practice guidelines.

Other Benefits. We have a retirement savings plan in which all of our employees age 18 and older are entitled to participate. Employees contribute their own funds, as salary deductions, on a pre-tax basis. Contributions may be made up to plan limits, subject to government limitations. The retirement savings plan permits us to make matching contributions if we choose and we have historically provided matching contributions of up to three percent, subject to a maximum amount. We provide health care, dental, vision and life insurance, employee assistance plans and both short- and long-term disability, accidental death and dismemberment benefits to all full-time employees, including our executive officers. These benefits are available to all employees, subject to applicable laws. We believe these benefits are consistent with companies with which we compete for employees.

Severance and Termination Protection

Employment Agreement. Under his employment agreement with us, Mr. Kiani is entitled to certain severance and change of control benefits, the terms of which are described in detail below under “—Employment Agreement and Offer Letters.”

Severance Protection Plan. Our Board of Directors adopted our 2007 Severance Protection Plan, which became effective on July 19, 2007 and was amended on December 31, 2008, the terms of which are described in detail below under “—2007 Severance Protection Plan.” Under the terms of this plan, participants are entitled to cash, equity and other benefits upon their termination under certain circumstances. Messrs. Allan, Coleman, de Raad, Fishel, Jansen, Lee and Sampath participate in our 2007 Severance Protection Plan. See “—2007 Severance Protection Plan” below.

Acceleration of Vesting of Equity-Based Awards. In the event of a change in control of us, certain provisions of our 1996 Plan and our 2004 Plan allow for 50% acceleration of unvested equity awards in the event an acquiror neither assumes awards outstanding under these plans nor issues our award holders substitute equity awards. In addition, our 2007 Plan permits acceleration of outstanding awards upon a change in control of us under certain circumstances. See “—Employee Benefit Plans” below.

Accounting and Tax Considerations

We adopted an accounting standard for share-based payments using the prospective method, which requires us to expense the estimated fair value of employee stock options and similar awards based on the fair value of the award on the date of grant. To calculate the fair value of stock options, we use the Black-Scholes option pricing model which requires the input of subjective assumptions. These assumptions include estimating the length of time employees will retain their vested stock options before exercising them, the estimated volatility of our stock price over the expected term and the number of options that will ultimately be forfeited prior to meeting their vesting requirements.

Internal Revenue Code Section 162(m) limits the amount that we may deduct for compensation paid to our Chief Executive Officer and to each of our three other most highly compensated executive officers (other than our chief financial officer) to $1 million per person unless certain exemption requirements are met. Exemptions to this deductibility limit may be made for various forms of “performance-based compensation.” All annual cash compensation paid to our executive officers for 2007 and prior years did not exceed $1 million per person, so the compensation has been deductible. Cash compensation paid to Mr. Kiani for 2008 and 2009 exceeded $1 million and therefore $404,923 and $29,600 of his compensation was not deductible by us in 2008 and 2009, respectively. In 2010, cash compensation paid to Mr. Kiani did not exceed $1 million. In addition to salary and bonus compensation, upon the exercise of stock options that are not treated as incentive stock options, the excess of the current market price over the option price, or option spread, is treated as compensation and accordingly, in any year, such exercise may cause an officer’s total compensation to exceed $1 million. Under certain regulations, option spread compensation from options that meet certain requirements will not be subject to the $1 million cap on deductibility, and in the past we have granted options that met those requirements. The Compensation Committee has not established a policy for determining which forms of incentive compensation awarded to our executive officers shall be designed to qualify as “performance-based compensation.” To maintain flexibility in compensating our executive officers in a manner designed to promote our objectives, the Compensation Committee has not adopted a policy that requires all compensation to be deductible. However, our Compensation Committee may evaluate the effects of the compensation limits of Section 162(m) of the Code on any compensation it proposes to grant. The Compensation Committee intends to provide future compensation in a manner consistent with our best interests and those of our stockholders.

Compensation Recovery

Under the Sarbanes-Oxley Act, in the event of misconduct that results in a financial restatement that would have reduced a previously paid incentive amount, we can recover those improper payments from our chief executive officer and chief financial officer. We recently adopted a clawback policy in accordance with the requirements of the Dodd-Frank Act, which provides that in the event we are required to restate our financial statements as a result of “material noncompliance” with financial reporting requirements under the securities laws, we will recover from our current and former “executive officers” any “incentive-based compensation”

(including stock option awards) that is (i) based on “erroneous data,” (ii) received during the “three-year period preceding the date on which the Company becomes required to prepare an accounting restatement,” and (iii) in excess of what would have been paid if calculated under the restatement. Once the SEC issues regulations or guidance regarding the required form of a clawback policy under the Dodd-Frank Act, we expect to amend our clawback policy accordingly.

Compensation Policies and Practices

Our compensation program is intended to reward the management team and other employees for strong performance over the long-term, with consideration to near-term actions and results that strengthen and protect Masimo. We consider the potential risks in our business when designing and administering our pay program, and we believe our balanced approach to performance measurement and pay delivery works to avoid misaligned incentives for individuals to undertake excessive or inappropriate risk. Further, program administration is subject to internal controls, and when determining the principal outcomes—performance assessments and pay decisions—we rely on principles of sound governance and good business judgment.

Summary Compensation Table

The following table provides information regarding the compensation earned during the fiscal year ended January 1, 2011 by our chief executive officer, our chief financial officer, and our three other most highly compensated executive officers who were employed with us as of January 1, 2011. We refer to these five individuals collectively as our “named executive officers.” We generally pay bonuses in the year following the year in which the bonus was earned. We did not grant any type of equity award other than stock options to our named executive officers or other employees during the year ended January 1, 2011.

Amounts set forth in the “Option Awards” column for 2008, 2009 and 2010 reflect the grant date fair value of option awards granted in the year indicated, computed in accordance with authoritative accounting guidance. All of these amounts reflect certain assumptions with respect to these option awards and do not correspond to the actual value that will be recognized by the named executive officers. The actual value, if any, that may be realized from an option award is contingent upon the satisfaction of the conditions to vesting in that award, and upon the excess of the stock price over the exercise price, if any, on the date the option award is exercised. See Note 11 of the Notes to Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended January 1, 2011 filed with the SEC on February 16, 2011, for a discussion of assumptions made in determining the grant date fair value of the stock options granted in our fiscal years 2008, 2009 and 2010.

In 2008, our Compensation Committee adopted an accrued vacation payout policy. At the time the policy was adopted, if any employee had accrued vacation in an amount equal to greater than the amount of vacation the employee accrued on an annual basis, then we paid the employee cash consideration for the full amount of accrued vacation above the employee’s annual accrued vacation rate. The policy applies equally to all of our employees.

Grants of Plan-Based Awards During Fiscal Year 2010

The following table presents information concerning grants of plan-based awards to each of the named executive officers during the year ended January 1, 2011. For the fiscal year ended January 1, 2011, we granted options to purchase an aggregate of 999,850 shares of our common stock, with a weighted average exercise price of $26.20 per share, to our employees, including grants to our named executive officers. The options included in the table below were issued under our 2007 Plan. Options granted under our 2007 Plan expire ten years from the date of grant. We did not grant any type of equity awards other than stock options to our named executive officers or other employees during the year ended January 1, 2011. See “—Employee Benefit Plans—2007 Stock Incentive Plan.”

The exercise price per share of each option granted to our named executive officers was equal to the fair market value of our common stock, as determined by our Compensation Committee, on the date of the grant. The exercise price is payable in cash or by check, in shares of our common stock previously owned by the optionee, subject to certain limitations, pursuant to a cashless exercise program approved by our Compensation Committee or through any combination of the foregoing.

For each named executive officer, the shares listed in this table are subject to a single stock option award carrying the varying exercise prices as set forth herein. The shares subject to each stock option vest over a five-year period, with 20% of the shares subject to the option vesting on each anniversary of the grant date, with partial or full vesting under certain circumstances upon a change in control of Masimo or various events specified in the named executive officer’s employment agreement or severance plan agreement, if applicable. The option awards remain exercisable until they expire ten years from the date of grant subject to earlier expiration following termination of employment.

⁽²⁾	20% of the shares subject to the option became exercisable on each of 5/24/08, 5/24/09 and 5/24/10 and, subject to such earlier expiration or accelerated exercisability, 20% of the unexercisable shares relating to the option award will become exercisable on each of 5/24/11 and 5/24/12.

Employment Agreement and Offer Letters

Employment Agreement with Joe Kiani

In April 2007, we entered into an employment agreement with Mr. Kiani, our Chief Executive Officer. The agreement automatically renews on a daily basis and terminates three years from the date either party gives notice of termination to the other party.

The current employment agreement sets forth Mr. Kiani’s base salary of $706,992 per year, which is subject to adjustment by our Board or our Compensation Committee. Mr. Kiani is entitled to receive an annual bonus equal to 50% of his base salary in the event we attain certain financial goals set by our Board or our Compensation Committee. The employment agreement also entitles Mr. Kiani to participate in or receive benefits under all of our employee benefits plans and to be eligible to participate in any bonus plan created for the payment of bonuses to members of our management. In addition, the agreement provides that we will reimburse Mr. Kiani for all reasonable expenses incurred and paid by him in the course of the performance of his duties under the agreement and that we will further reimburse him for all reasonable travel and lodging expenses for his immediate family in the event his immediate family accompanies him during business travel. Under the employment agreement, “reasonable” expenses include travel and hospitality expenses for first class airplane travel and accommodations and expenses for travel using private or chartered aircraft. Mr. Kiani is exempt from our travel and expense policy and our expense reimbursement policy. In addition, under the agreement, each year Mr. Kiani is entitled to receive an additional payment equal to, after taxes, the amount of the taxes incurred by him under federal and state regulations pursuant to the expense reimbursement he received for the immediately preceding year under our reimbursement policy.

Under the employment agreement, we may terminate Mr. Kiani’s employment for “cause,” as a result of his disability under certain circumstances or for any other reason. Similarly, Mr. Kiani may terminate his employment for “good reason,” for health reasons or for any other reason upon six months written notice to us. If Mr. Kiani is terminated for cause, he is entitled to receive his full base salary through the date of termination. If Mr. Kiani’s employment is terminated as a result of his death, his designee or estate is entitled to receive his full base salary through the date of termination and an additional amount equal to 50% of his base salary in effect as of the date of his death for each of three consecutive years following his death, which shall be paid in substantially equal monthly installments over the three-year period. If Mr. Kiani’s employment is terminated as a result of his disability, he is entitled to receive his full base salary through the date of termination and an additional amount equal to 75% of his base salary then in effect for each of two consecutive years following the date of termination, which shall be paid in substantially equal monthly installments over the two-year period. If we terminate Mr. Kiani’s employment other than for cause, death or disability, or if Mr. Kiani terminates his employment with us for good reason, (i) he is entitled to receive his full base salary through the date of termination and an additional amount equal to two times the sum of his base salary then in effect plus the average annual bonus paid to Mr. Kiani over the prior three years, which shall be paid in installments over two years pursuant to our normal payroll practices, (ii) all of Mr. Kiani’s outstanding options will immediately vest, and (iii) we will be required to pay the full exercise price of all vested options held by Mr. Kiani, as well as all withholding taxes on the issuance of the shares underlying the vested options. In addition, Mr. Kiani shall be entitled to receive the foregoing payments and benefits in the event of a change in control of us or our Board. The cash payments must be paid to Mr. Kiani within thirty days of the change in control. Following a change in control, Mr. Kiani would not be entitled to receive any additional payments under the employment agreement.

In addition, if Mr. Kiani’s employment is terminated for any reason other than cause or as a result of his death, he will be entitled to participate in all of our employee benefit plans and programs that he participated in as of the date of his termination for the full term of his employment agreement as long as his participation is possible under the general terms and provisions of the plans. If for any reason Mr. Kiani is not permitted to participate in any of our employee benefit plans or programs after the date of his termination, he will be entitled to reimbursement of the amount paid by Mr. Kiani to obtain similar coverage to that offered by our benefit plans and programs but only for an amount up to the amount we would otherwise have paid on behalf of Mr. Kiani as

an employee of ours under his employment agreement as of the date of his termination. The foregoing benefits and payments may be subject to a delay of up to six months as necessary to avoid the imposition of additional tax under Section 409A of the Code.

For purposes of Mr. Kiani’s employment agreement, termination for “cause” generally means his termination as a result of his willful and continued failure to substantially perform his duties under his employment agreement, his willful engaging in gross misconduct materially injurious to us or his willful violation of the provisions of his confidentiality agreement with us if the violation results in demonstrably material injury to us. Any termination for cause must be approved by at least 75% of the entire membership of our Board. Termination for “good reason” under the employment agreement generally means as a result of our assignment to Mr. Kiani of any duties other than those contemplated by his employment agreement, a reduction in Mr. Kiani’s rate of compensation or fringe benefits or certain failures by us to comply with the compensation terms of the employment agreement. A “change in control” under the employment agreement generally means (i) the acquisition by any person or group of more than 35% of our outstanding voting stock, (ii) the acquisition of our assets that have a total fair market value of 40% or more of the total fair market value of all of our assets immediately before the acquisition by any person or group, or (iii) a change in a majority of the members of our Board in a rolling twelve month period, subject to certain limitations.

Under the employment agreement, if any payments or benefits payable to Mr. Kiani would be subject to the excise tax under Section 4999 of the Code, Mr. Kiani will be entitled to receive an additional “gross-up” payment to cover the amount of the excise taxes other than taxes imposed by Section 409A of the Code. An independent registered public accounting firm will make the initial determination as to whether a gross-up payment is required under the employment agreement.

See “—Potential Payments upon Termination or Change in Control” below.

Offer Letters with Other Executive Officers

Messrs. Allan, Coleman, de Raad, Fishel, Jansen, Lee, O’Reilly, Paul and Sampath each signed an offer letter before commencing their employment with us. The offer letters set forth each officer’s position and title, starting salary, health benefits, number of options received and the vesting schedule of such options. Additionally, each offer letter states that the officer’s employment is “at-will” and may be terminated at any time by either the officer or us for any reason. See “—Potential Payments upon Termination or Change in Control” below.

Employee Proprietary Agreements

Each of our named executive officers has also entered into a standard form agreement with respect to proprietary information and inventions. Among other things, this agreement obligates each named executive officer to refrain from disclosing any of our proprietary information received during the course of his employment and, with some exceptions, to assign to us any inventions conceived or developed during the course of his employment.

Cash Bonus Plans

In July 2007, our Board approved the following cash bonus plans, both of which cover our named executive officers:

Executive Annual Cash Bonus Award Plan

The purpose of our Executive Annual Plan is to provide our executive officers with additional incentives to deliver exceptional financial and operational results on an annual basis. Our Executive Annual Plan became effective on January 1, 2007.

Administration. The Executive Annual Plan is administered by our Board or committee designated by the Board, which is referred to as the Administrator. Our Board has authorized our Compensation Committee to act as the Administrator. The Administrator has the right to construe the Executive Annual Plan, and to determine any factual or legal question arising in connection with the operation of the plan. In addition, the Administrator has the unilateral right to amend, suspend, modify or terminate the Executive Annual Plan at any time with respect to all or some executives and with respect to any unpaid bonuses that are or could have become payable, whether for the current or future years.

Eligibility. Any of our executive officers may participate in the Executive Annual Plan if the Administrator so determines pursuant to guidelines set forth in the plan. In addition, the Administrator may select other officers and key employees to participate in the Executive Annual Plan. However, unless the Administrator determines otherwise in writing for a particular plan year, an executive officer or other employee may not participate in the Executive Annual Plan if he or she is normally scheduled to work an average of less than forty hours per week or if the executive or other employee works for us for less than six months and one day during the applicable plan year. In addition, the Executive Annual Plan does not cover any executive or other employee who is covered by another cash bonus arrangement or non-equity variable compensation plan with us during the applicable plan year, excluding any severance plan or agreement with us and our Executive Multi-Year Plan discussed below. Each of our current executive officers was eligible to receive a cash bonus under the Executive Annual Plan for 2010.

Bonus Amounts and Payments. We pay bonuses for a plan year under the Executive Annual Plan if and only if the Administrator has approved written resolutions that either establish the terms and conditions relating to the payment of bonuses that will apply for the plan year, or otherwise approve the payment of bonuses. Our executives are entitled to bonuses only if they are still employed by us when we actually pay bonuses under the plan.

Under the Executive Annual Plan, our executives are eligible to receive an annual cash bonus based on our achievement of certain financial and other performance targets established by the Compensation Committee, as well as other quantitative and qualitative factors established by our Chief Executive Officer for the other named executive officers. Pursuant to the terms of the Executive Annual Plan, the bonus award for each named executive officer is calculated based upon the product of (A) the named executive officer’s base salary as of the last day of the plan year, multiplied by (B) (i) the target bonus percentage factor assigned to the job classification level of the named executive officer, multiplied by (ii) the company percentage factor assigned by the Compensation Committee based upon the attainment of financial and other performance measures established by the Compensation Committee during the first three months of the plan year, multiplied by (iii) the named executive officer’s individual percentage factor assigned by the Chief Executive Officer for the other named executive officers and, in the case of our Chief Executive Officer, assigned by the Compensation Committee. Under the Executive Annual Plan, the Compensation Committee has the discretion to pay a higher bonus amount by substituting in the above-referenced calculation a “maximum bonus percentage” for each participant’s “target bonus percentage factor” for any plan year based upon the participant’s job classification level. Amounts payable under the Executive Annual Plan are pro rated based on the number of full weeks during the plan year in which the participant is employed with us.

For purposes of the company percentage factor, in the event the Compensation Committee determines that we achieve (i) less than 100% of the financial and other performance targets for the plan year, it has the discretion to set the company percentage factor at any percentage, including zero, (ii) 100% of the financial and other performance measures for the plan year, the company percentage factor shall automatically be set at 100%, and (iii) more than 100% of the financial and other performance targets for the plan year, it has the discretion to set the company percentage factor at any percentage at or above 100%. For the bonuses paid for 2008, 2009 and 2010, the target bonus percentage factor assigned to the position of chief executive officer was 50% and the target bonus percentage factor assigned the positions of our other executive officers was 40%. Under the Executive Annual Plan, each named executive officer’s individual percentage factor could range from 0% to

100%. For all of our named executive officers other than our Chief Executive Officer, the individual percentage factor is determined by our Chief Executive Officer based upon our Chief Executive Officer’s subjective determination of the participant’s overall performance, taking into account such factors and goals assigned to the participant during the plan year. For purposes of determining the individual factor of our Chief Executive Officer under the Executive Annual Plan, the Compensation Committee makes a subjective determination of the Chief Executive Officer’s overall performance during the plan year, provided that in the event the Compensation Committee establishes the company percentage factor at or above 100%, our Chief Executive Officer’s individual percentage factor is automatically set at 100%.

Executive Multi-Year Cash Bonus Award Plan

The purpose of our Executive Multi-Year Plan is to provide our executive officers with additional incentives to deliver exceptional financial and operational results over a three-year period. The Executive Multi-Year Plan became effective on January 1, 2008.

Administration. The Executive Multi-Year Plan is administered by our Board or a committee designated by the Board, which is referred to as the Administrator. Our Board has authorized our Compensation Committee to act as the Administrator. The Administrator has the right to construe the Executive Multi-Year Plan, and to determine any factual or legal question arising in connection with the operation of the Executive Multi-Year Plan. In addition, the Administrator has the unilateral right to amend, suspend, modify or terminate the Executive Multi-Year Plan at any time with respect to all or some executives and with respect to any unpaid bonuses that are or could have become payable, whether for the current or future years.

Eligibility. Any of our executive officers may participate in the Executive Multi-Year Plan if the Administrator so determines pursuant to guidelines in the plan. In addition, the Administrator may select other officers and key employees to participate in the Executive Multi-Year Plan. However, unless the Administrator determines otherwise in writing for a particular plan period, an executive officer or other employee may not participate in the Executive Multi-Year Plan if he or she is normally scheduled to work an average of less than forty hours per week or if the executive or other employee is not employed by us for the last eighteen months of the three-year plan period. In addition, the Executive Multi-Year Plan does not cover any executive or other employee who is covered by another cash bonus arrangement or non-equity variable compensation plan with us during the applicable plan period excluding any severance plan or agreement with us and our Executive Annual Plan. Each of our current executive officers, except Mr. Allan, was eligible to receive a cash bonus under the Executive Multi-Year Plan for the 2008 through 2010 plan period.

Bonus Amounts and Payments. We pay bonuses for a plan period under the Executive Multi-Year Plan if and only if the Administrator has approved written resolutions that either establish the terms and conditions relating to the payment of bonuses that will apply for the plan period, or otherwise approve the payment of bonuses. Each plan period is comprised of three consecutive calendar years. The first plan period under the Executive Multi-Year Plan began on January 1, 2008 and ended on December 31, 2010. Our executives are entitled to bonuses only if they are still employed by us when we actually pay bonuses under the plan.

Under the Executive Multi-Year Plan, our executives are eligible to receive a cash bonus at the end of an applicable three-year bonus period based on our achievement of certain financial targets established by our Compensation Committee. Pursuant to the terms of the Executive Multi-Year Plan, the bonus award for each named executive officer is calculated based upon the product of (A) three times the named executive officer’s average salary over the three-year plan period, multiplied by (B) (i) the multi-year performance bonus percentage factor assigned to the job classification level of the named executive officer, multiplied by (ii) the company percentage factor assigned by the Compensation Committee based upon the attainment of financial measures established by our Compensation Committee during the first three months of the plan period, multiplied by (iii) the named executive officer’s individual percentage factor assigned by the Chief Executive Officer for the

other named executive officers and in the case of our Chief Executive Officer, assigned by the Compensation Committee. Amounts payable under the Executive Multi-Year Plan are pro rated based on the number of full weeks during the plan period in which the participant is employed with us.

Under the Executive Multi-Year Plan, the performance bonus percentage factor is based on the job classification of our employees and other key employees. Our Chief Executive Officer is at the highest job classification, which corresponded to a target bonus percentage of 50% for the 2008 through 2010 plan period, as determined by our Compensation Committee. The target bonus percentage of our other executive officers was set at 40% for the 2008 through 2010 plan period by our Compensation Committee.

For purposes of the company percentage factor, in the event the Compensation Committee determines that we achieve (i) less than 100% of the financial measures for the plan period, it has the discretion to set the company percentage factor at any percentage, including zero; (ii) 100% of the financial measures for the plan period, the company percentage factor shall automatically be set at 100%; and (iii) more than 100% of the financial measures for the plan period, it has the discretion to set the company percentage factor at any percentage at or above 100%.

Under the Executive Multi-Year Plan, each named executive officer’s individual percentage factor could range from 0% to 100%. For all of our named executive officers other than our Chief Executive Officer, the individual percentage factor is determined by our Chief Executive Officer based upon our Chief Executive Officer’s subjective determination of the participant’s overall performance, taking into account such factors and goals assigned to the participant during the plan period. For purposes of determining the individual factor of our Chief Executive Officer under the Executive Multi-Year Plan, the Compensation Committee makes a subjective determination of the Chief Executive Officer’s overall performance during the plan period, provided that in the event the Compensation Committee establishes the company percentage factor at or above 100%, then our Chief Executive Officer’s individual percentage factor is automatically set at 100%.

Employee Benefit Plans

Third Amended and Restated 1996 Incentive Stock Option, Nonqualified Stock Option and Restricted Stock Purchase Plan

Our 1996 Plan was initially adopted by our Board and approved by our stockholders in May 1996. The 1996 Plan terminated automatically on May 4, 2006 and we cannot grant any additional awards thereunder. However, options outstanding under the 1996 Plan will continue to be governed by their existing terms under the 1996 Plan. Any shares of our common stock that are issuable pursuant to options outstanding under our 1996 Plan that hereafter would otherwise become available for future grant under the 1996 Plan will be automatically added to the share reserve of our 2007 Plan. See “—2007 Stock Incentive Plan” below.

Awards. The 1996 Plan provided for grants of the following:

•

incentive stock options (“ISOs”), as defined under the Code, which could be granted solely to our employees, including officers and employee directors;

•

nonqualified stock options (“NSOs”), which could be granted to our directors, consultants or employees, including officers; and

•

stock purchase rights, which could be granted to our directors, consultants or employees, including officers. We did not grant any stock purchase rights under the 1996 Plan.

Share Reserve. As of February 28, 2011, an aggregate of 303,260 shares of our common stock were reserved for issuance under the 1996 Plan, comprised solely of options to purchase shares of common stock outstanding as of such date. Shares issued under the 1996 Plan may be previously unissued shares or reacquired shares bought on the market or otherwise.

Administration. Authority to control and manage the operation and administration of the 1996 Plan was vested with the Board, which was permitted to delegate some or all of such responsibilities to a committee. In this discussion, we refer to our Board and the Compensation Committee collectively as the Administrator. Subject to the terms of the 1996 Plan, the Administrator had the power to determine, among other things, the terms of the options or stock purchase rights granted, including the exercise price of the option or stock purchase right, the designation of stock options as ISOs or NSOs, the number of shares issuable under each option or stock purchase right, the exercisability of each option or stock purchase right, and the form of consideration payable upon the exercise of each option or stock purchase right. The Administrator also had the authority to amend, suspend or terminate the 1996 Plan, so long as no such action affected any shares of common stock previously issued and sold or any option previously granted under the 1996 Plan. During any calendar year, each optionee could only be granted options to purchase a maximum of 1,500,000 shares.

Stock Options. All stock options granted under the 1996 Plan were granted pursuant to a stock option agreement. Under the 1996 Plan, the exercise price of all ISOs granted under the 1996 Plan had to be at least equal to the fair market value of our common stock on the date of grant. The exercise price of NSOs granted under the 1996 Plan was determined by the Administrator, but in no event could be less than 85% of fair market value. For NSOs intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the exercise price had to be at least equal to the fair market value of our common stock on the date of grant. For any participant who owned stock representing more than 10% of the voting power of all classes of our outstanding capital stock, the exercise price of any incentive stock option granted had to be at least equal to 110% of the fair market value on the grant date and the term of such incentive stock option could not exceed five years. The aggregate fair market value, determined at the time of grant, of shares of our common stock subject to ISOs that are exercisable for the first time by an optionee during any calendar year under all of our stock plans could not exceed $100,000. The options or portions of options that exceed this limit are treated as NSOs. Stock options vest at the rate specified in the stock option agreement, as determined by the Administrator.

In general, the term of all other options granted under the 1996 Plan does not exceed ten years. If a participant’s service relationship with us, or any affiliate of ours, terminates due to disability or death, the participant, or his or her beneficiary, may exercise any vested options during the one-year period immediately following termination of service, unless such options expire prior to such time. If an optionee’s relationship with us, or any affiliate of ours, ceases for any reason other than disability or death, the optionee may exercise any vested options during the three-month period immediately following the termination of service, unless such options expire prior to such time.

Applicable forms of consideration for the exercise of options granted under the 1996 Plan were determined by the Administrator and may include cash or common stock previously owned by the optionee that have been held by the participant for at least six months, or payment through delivery of a promissory note, cancellation of indebtedness, a deferred payment arrangement, a broker-assisted exercise or other legal consideration or arrangements approved by the Administrator.

Options granted under our 1996 Plan are generally not transferable by the optionee, other than by will or the laws of descent and distribution, and each option is exercisable during the lifetime of the optionee only by such optionee.

Change in Control. Under the 1996 Plan and the forms of option agreement used under the 1996 Plan, in the event of a change in control of us, 50% of the unvested shares subject to outstanding options or repurchase rights will become fully vested and the Administrator may further:

•

provide for the purchase of each outstanding option or stock purchase right for an amount of cash or other property that could have been received upon the exercise of the option or stock purchase right as if they had been exercisable;

•

adjust the terms of the options and stock purchase rights in a manner determined by the Administrator to reflect the merger or sale of assets causing the change in control;

•

cause the options and stock purchase rights to be assumed by, or substituted with comparable rights by the successor corporation; or

•

make such other provisions as the Administrator may consider equitable.

If the Administrator does not take any of the foregoing actions, all options and stock purchase rights shall terminate upon the change in control, and the Administrator must provide written notice of the proposed transaction to be given to all participants not less than fifteen days prior to the effective date of the transaction.

2004 Incentive Stock Option, Nonqualified Stock Option and Restricted Stock Purchase Plan

Our 2004 Plan was initially adopted by our Board and initially approved by our stockholders in April 2004. Unless terminated sooner, the 2004 Plan will terminate automatically pursuant to its terms in April 2014. Upon completion of our initial public offering in August 2007, at which time our 2007 Stock Incentive Plan became effective, all of the options available for future grant under our 2004 Plan as of such time automatically became reserved for awards issuable under our 2007 Plan. In addition, any shares of our common stock that are issuable pursuant to options outstanding under our 2004 Plan that hereafter would otherwise become available for future grant under the 2004 Plan will be automatically added to the share reserve of our 2007 Plan. See “—2007 Stock Incentive Plan” below. No further equity awards may be made under our 2004 Plan. However, options outstanding under the 2004 Plan will continue to be governed by their existing terms under the 2004 Plan.

Awards. The 2004 Plan provides for the grant of the following:

•

ISOs, which may be granted solely to our employees, including our executive officers; and

•

NSOs, which may be granted to our directors, consultants or employees, including officers; and

•

stock purchase rights, which may be granted to our directors, consultants or employees, including officers. We did not grant any stock purchase rights under the 2004 Plan.

Share Reserve. As of February 28, 2011, an aggregate of 2,038,037 shares of our common stock were reserved for issuance under the 2004 Plan, comprised solely of options to purchase shares of common stock outstanding as of such date. Shares issued under the 2004 Plan may be previously unissued shares or reacquired shares bought on the market or otherwise.

Administration. Authority to control and manage the operation and administration of the 2004 Plan is vested with the Board, which may delegate some or all of such responsibilities to a committee. In this discussion, we refer to our Board and the Compensation Committee collectively as the Administrator. Subject to the terms of the 2004 Plan, the Administrator has the power to determine, among other things, the terms of the options or stock purchase rights granted, including the exercise price of the option or stock purchase right, the designation of stock options as ISOs or NSOs, the number of shares issuable under each option or stock purchase right, the exercisability of each option or stock purchase right, and the form of consideration payable upon the exercise of each option or stock purchase right. The Administrator has the authority to amend, suspend or terminate the 2004 Plan, so long as no such action affects any shares of common stock previously issued and sold or any option previously granted under the 2004 Plan. During any calendar year, each optionee may be granted options to purchase a maximum of 500,000 shares under the 2004 Plan.

Stock Options. All stock options granted under the 2004 Plan were granted pursuant to a stock option agreement. The exercise price of all ISOs granted under the 2004 Plan must be at least equal to the fair market value of our common stock on the date of grant. The exercise price of NSOs granted under the 2004 Plan is determined by the Administrator, but in no event may be less than 85% of fair market value. For NSOs intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the exercise price must be at least equal to the fair market value of our common stock on the date of grant. For any participant who owns stock representing more than 10% of the voting power of all classes of our outstanding capital stock, the exercise price

of any incentive stock option granted must be at least equal to 110% of the fair market value on the grant date and the term of such incentive stock option must not exceed five years. The aggregate fair market value, determined at the time of grant, of shares of our common stock subject to ISOs that are exercisable for the first time by an optionee during any calendar year under all of our stock plans may not exceed $100,000. The options or portions of options that exceed this limit are treated as NSOs. Stock options vest at the rate determined by the Administrator, provided that at least 20% of the shares subject to any option shall become exercisable each year over a five-year period. At the discretion of the Administrator, the stock option agreement may provide that for ninety days following termination of a participant’s employment with us or one of our subsidiaries, we will have the right to repurchase, at the fair market value of our common stock, any shares issued to a participant pursuant to the exercise of an option.

In general, the term of all other options granted under the 2004 Plan may not exceed ten years. If a participant’s service relationship with us, or any affiliate of ours, terminates due to disability or death, the participant, or his or her beneficiary, may exercise any vested options during the one-year period immediately following termination of service, unless such options expire prior to such time. If an optionee’s relationship with us, or any affiliate of ours, ceases for any reason other than disability or death, the optionee may exercise any vested options during the forty-five day period immediately following the termination of service, unless such options expire prior to such time. In the event a participant’s service relationship with us, or any affiliate of ours, terminates other than due to disability or death, we have the right to repurchase from the participant any shares of common stock issued to the participant under the 2004 Plan at a purchase price equal to the fair market value of our common stock as of the date the participant’s service terminated. The repurchase right may be exercised at any time during the ninety day period following the date of the participant’s termination.

Applicable forms of consideration for the exercise of options granted under the 2004 Plan will be determined by the Administrator and may include cash or common stock previously owned by the optionee that have been held by the participant for at least six months, or payment through a deferred payment arrangement, a broker-assisted exercise or other legal consideration or arrangements approved by the Administrator.

Options granted under our 2004 Plan are generally not transferable by the optionee, other than by will or the laws of descent and distribution, and each option is exercisable during the lifetime of the optionee only by such optionee.

Change in Control. Under the 2004 Plan and the forms of NSO and ISO agreements, in the event of a change in control of us:

•

in which the acquiror neither assumes the options outstanding under the 2004 Plan nor issues the 2004 Plan participants substitute stock options under the acquiror’s equity plan in exchange for the 2004 Plan stock options, then 50% of the unvested options outstanding under the 2004 Plan shall automatically become fully vested as of prior to the consummation of the change in control. The 2004 Plan participants would be entitled to exercise their vested options at any time prior to the change in control and all options outstanding under the 2004 Plan that are not exercised prior to the change in control would automatically terminate.

•

in which the acquiror elects to assume the options outstanding under the 2004 Plan, each plan participant’s options would continue to be governed by the terms of the 2004 Plan and his or her 2004 Plan option agreements. If, following the change in control, the participant remains employed with us or one of our subsidiaries, or the participant becomes an employee of the acquiror (or one of its affiliates), then 50% of the participant’s unvested options outstanding under the 2004 Plan shall automatically become fully vested in the event either the participant is terminated from employment without “cause” or the participant terminates his or her employment due to a “material negative change in job position.”

•

in which the acquiror elects to issue the 2004 Plan participants substitute options under the acquiror’s equity plan in exchange for terminating the participant’s 2004 Plan stock options, the substitute options would be governed by the terms of the acquiror’s equity plan and accompanying form of option

agreement. If, following the change in control, the participant remains employed with us or one of our subsidiaries, or the participant becomes an employee of the acquiror (or one of its affiliates), then 50% of the participant’s unvested options outstanding under the 2004 Plan shall automatically become fully vested in the event either the participant is terminated from employment without “cause” or the participant terminates his or her employment due to a “material negative change in job position.”

Under the 2004 Plan, a change in control generally includes:

•

an acquisition of 80% or more of our outstanding stock by any person or group;

•

a merger or consolidation of us after which our stockholders as of immediately prior to the merger or consolidation own 20% or less of the surviving entity;

•

a sale of all or substantially all of our assets; or

•

a complete liquidation or dissolution of Masimo.

For purposes of the 2004 Plan, “cause” means the participant’s conviction of a felony, an act of material dishonesty or fraud by the participant against us or our stockholders, or the participant’s willful breach of any duty owed by the participant to us or our subsidiaries and “material negative change in job position” means a reduction in the participant’s base compensation or a substantial diminution in the participant’s duties and responsibilities.

2007 Stock Incentive Plan

Our Board adopted our 2007 Stock Incentive Plan (the “2007 Plan”) in November 2006. The 2007 Plan was approved by our stockholders in June 2007 and became effective upon the effective date of our initial public offering on August 7, 2007. The 2007 Plan will terminate on August 7, 2017, unless our Board terminates it earlier.

Awards. The 2007 Plan provides for the grant of the following awards:

•

ISOs, which may be granted solely to our employees, including our executive officers; and

•

NSOs, stock appreciation rights, restricted stock awards, unrestricted stock awards, restricted stock unit awards and performance awards, which may be granted to our directors, consultants or employees, including our executive officers.

Purpose. The purpose of our 2007 Plan is to encourage and enable our directors, consultants and employees, including our executive officers, to acquire or increase their holdings of common stock and other interests in us in order to promote a closer identification of their interests with those of us and our stockholders, thereby further stimulating their efforts to enhance our efficiency, soundness, profitability, growth and stockholder value.

Administration. The 2007 Plan is administered by the Compensation Committee of our Board, provided that our Board may act in lieu of the Compensation Committee on any matter. In this discussion, we refer to our Board and the Compensation Committee collectively as the Administrator. Subject to the terms and conditions of the 2007 Plan, the Administrator is authorized to select participants, determine the type and number of awards to be granted and the number of shares to which awards will relate or the amount of a performance award, specify dates at which awards will be exercisable or settled, including performance conditions that may be required as a condition thereof, set other terms and conditions of such awards, prescribe forms of award agreements, interpret and specify rules and regulations relating to the 2007 Plan, and make all other determinations that may be necessary or advisable for the administration of the 2007 Plan. Acceptable forms of consideration for the purchase of our common stock issued under the 2007 Plan will be determined by the Administrator and may include cash, common stock previously owned by the participant, payment through a broker-assisted exercise or any combination of the foregoing. In addition, the Administrator may delegate its authority under the 2007 Plan to the extent permitted by the Delaware General Corporation Law, except delegation is limited where necessary

to meet requirements under Rule 16b-3 under the Exchange Act or Section 162(m) of the Code. Neither we nor the Administrator may reprice any stock option or stock appreciation right granted under the 2007 Plan without first obtaining the approval of our stockholders.

Share Reserve. As of February 28, 2011, an aggregate of 6,456,089 shares of our common stock were reserved for issuance under the Plan, plus the number of shares of our common stock that were previously authorized for issuance under our 1996 Plan and 2004 Plan that have become available for future issuance under those plans after the effectiveness of our 2007 Plan, and any additional shares that otherwise would have become available for future issuance under our 1996 Plan and 2004 Plan. In addition, unless otherwise provided by the Administrator, this amount will be automatically increased annually on the first day of each fiscal year by 3% of the aggregate number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year. Shares of our common stock subject to options and other stock awards that have expired or otherwise terminate under the 2007 Plan without having been exercised in full will again become available for grant under the 2007 Plan. Shares of our common stock issued under the 2007 Plan may include previously unissued shares or reacquired shares bought on the market or otherwise. If any shares of our common stock subject to a stock award are not delivered to a participant because such shares are withheld for the payment of taxes or the stock award is exercised through a net exercise, then the number of shares that are not delivered to participants shall again become available for grant under the 2007 Plan. In addition, if the exercise of any stock award is satisfied by tendering shares of our common stock held by the participant, then the number of shares tendered shall become available for grant under the 2007 Plan. The maximum number of stock options and stock appreciation rights that may be issued to a single participant in any calendar year under our 2007 Plan is 3,000,000 shares. As of February 28, 2011, there were 5,061,210 shares of common stock subject to options outstanding under our 2007 Plan.

Stock Options. Stock options will be granted pursuant to stock option agreements. The exercise price for stock options cannot be less than 100% of the fair market value of our common stock on the date of grant. Options granted under the 2007 Plan will vest at the rate specified in the option agreement. A stock option agreement may provide for early exercise of NSOs prior to vesting. Unvested shares of our common stock issued in connection with an early exercise may be repurchased by us upon termination of the participant’s service. In general, the term of stock options granted under the 2007 Plan may not exceed ten years. Unless the terms of a participant’s stock option agreement provide for earlier or later termination, if a participant’s service relationship with us, or any affiliate of ours, ceases for any reason other than for cause, disability or death, the participant may exercise any vested options for up to ninety days after the date the service relationship ends, unless the terms of the stock option agreement provide for a longer or shorter period to exercise the option. If a participant’s service relationship with us, or any affiliate of ours, ceases due to disability, the participant may exercise any vested options for up to one year after the date the service relationship ends. If a participant’s service relationship with us, or any affiliate of ours, ceases due to death, or the participant dies within thirty days following the date the service relationship ends other than for cause, the participant’s beneficiary may exercise any vested options for up to one year following the date of death. If a participant’s relationship with us, or any affiliate of ours, ceases due to termination for cause, the option will terminate at the time the participant’s relationship with us, or an affiliate of ours, terminates. In no event may an option be exercised after its expiration date.

Incentive stock options may be granted only to our employees, including executive officers. The aggregate fair market value, determined at the time of grant, of shares of our common stock with respect to ISOs that are exercisable for the first time by a participant during any calendar year under all of our equity plans may not exceed $100,000. The options or portions of options that exceed this limit are automatically treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock representing more than 10% of the total combined voting power of us or any affiliate of ours unless the following conditions are satisfied:

•

the option exercise price is at least 110% of the fair market value of our common stock on the date of grant; and

•

the term of the ISO does not exceed five years from the date of grant.

Stock Appreciation Rights. Stock appreciation rights will be granted through a stock appreciation rights agreement. Each stock appreciation right is denominated in common stock equivalents. The exercise price of each stock appreciation right will be determined by the Administrator at the time of grant and will not be less than 100% of the fair market value of the common stock underlying the right. In general, the term of a stock appreciation right may not exceed ten years. Upon exercise of a stock appreciation right, we will pay the participant an amount equal to the excess of (i) the aggregate fair market value of our common stock on the date of exercise, over (ii) the aggregate exercise price determined by the Administrator on the date of grant. Stock appreciation rights will be paid either in cash, in shares of our common stock or partly in cash and partly in shares. Unless otherwise provided in a stock appreciation rights agreement, all stock appreciation rights will be settled in shares of our common stock, with cash paid for fractional shares. The administrator may also impose any restrictions or conditions upon the vesting of stock appreciation rights that it deems appropriate. A recipient’s stock appreciation rights agreement shall specify the terms upon which the recipient may exercise a stock appreciation right in the event the recipient’s relationship with us, or any affiliate of ours, ceases for any reason. Absent this disclosure, a stock appreciation right shall be governed by the same post-termination provisions applicable to options granted under the 2007 Plan, as discussed above. Stock appreciation rights carry no voting or dividend rights or other rights associated with stock ownership.

Restricted and Unrestricted Stock Awards. Restricted stock awards will be granted pursuant to restricted stock award agreements. A restricted stock award may be issued for nominal or no cost and may be granted in consideration for the recipient’s past or future services performed for us or an affiliate of ours. Participants receiving a restricted stock award generally have all of the rights of a stockholder with respect to such stock, including rights to vote the shares and receive dividends. Shares of our common stock acquired under a restricted stock award will be subject to forfeiture to us in accordance with vesting conditions based upon a schedule or performance criteria established by the Administrator. Generally, except as otherwise provided in the applicable restricted stock award agreement, restricted stock awards that have not vested will be forfeited upon the participant’s termination of continuous service with us or an affiliate of ours for any reason. We will return the purchase price for a forfeited restricted stock award only if set forth in the participant’s restricted stock award agreement.

Unrestricted stock awards are similar to restricted stock awards, provided that shares of our common stock acquired under an unrestricted stock award will be fully vested on the date of grant.

Restricted Stock Unit Awards. Restricted stock unit awards will be granted pursuant to restricted stock unit award agreements. Restricted stock units are denominated in common stock equivalents. They are typically awarded to participants without payment of consideration, but are subject to vesting conditions based upon a schedule or performance criteria established by the Administrator. Unlike restricted stock, the stock underlying restricted stock units will not be issued until the stock units have vested. Prior to settlement, restricted stock unit awards carry no voting or dividend rights or other rights associated with stock ownership, but unless otherwise provided in a participant’s restricted stock unit award agreement, dividend equivalents will accrue from the date the award is granted until the date the shares underlying a restricted stock unit are issued. Except as otherwise provided in the applicable restricted stock unit award agreement, restricted stock units that have not vested will be forfeited upon the participant’s termination of continuous service with us or an affiliate of ours for any reason.

Performance Awards. Performance awards may be granted, vest or be exercised based upon the attainment of certain performance goals during a certain period of time. The performance awards may be issued as performance-based compensation that is not subject to the income tax deductibility limitations imposed by Section 162(m) of the Code if the grant or vesting of one or more stock awards and the delivery of cash is tied solely to the attainment of certain performance goals during a designated performance period. The length of any performance period, the performance goals to be achieved during the performance period and the measure of whether and to what degree such performance goals have been attained shall be determined by the Administrator. The maximum amount to be received by any individual in any performance period, which shall not be less than one fiscal year, under performance awards issued under the 2007 Plan may not exceed 3,000,000 shares of our common stock and $1,000,000 in cash.

Internal Revenue Code Section 409A Requirements. Certain awards under the 2007 Plan may be considered “nonqualified deferred compensation” for purposes of Section 409A of the Code (“Section 409A”), which imposes certain requirements on compensation that is deemed under Section 409A to involve nonqualified deferred compensation. Among other things, the requirements relate to the timing of elections to defer, the timing of distributions and prohibitions on the acceleration of distributions. Failure to comply with these requirements (or an exception from such requirements) may result in the immediate taxation of all amounts deferred under the nonqualified deferred compensation plan for the taxable year and all preceding taxable years, by or for any participant with respect to whom the failure relates, the imposition of an additional 20% income tax on the participant for the amounts required to be included in gross income and the possible imposition of penalty interest on the unpaid tax. Generally, Section 409A does not apply to incentive awards that are paid at the time the award vests. Likewise, Section 409A typically does not apply to restricted stock. Section 409A may, however, apply to incentive awards the payment of which is delayed beyond the calendar year in which the award vests. Treasury regulations generally provide that the type of awards provided under the 2007 Plan will not be considered nonqualified deferred compensation. However, to the extent that Section 409A applies to an award issued under the 2007 Plan, the 2007 Plan and all such awards will, to the extent practicable, be construed in accordance with Section 409A. Under the 2007 Plan, the Administrator has the discretion to grant or to unilaterally modify any award issued under the 2007 Plan in a manner that conforms with the requirements of Section 409A with respect to deferred compensation or voids any participant election to the extent it would violate Section 409A. The Administrator also has sole discretion to interpret the requirements of the Code, including Section 409A, for purposes of the 2007 Plan and all awards issued under the 2007 Plan.

Transferability of Awards. Generally, a participant may not transfer an award granted under the 2007 Plan other than by will or the laws of descent and distribution. However, a participant may transfer an NSO pursuant to a domestic relations order. In addition, if provided in an award agreement, NSOs, stock appreciation rights settled in shares, restricted stock awards and performance awards granted under the 2007 Plan may be transferred by instrument to the participant’s immediate family or an inter vivos or testamentary trust or by gift to charitable institutions.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure not involving the receipt of consideration by us, such as a stock split, stock dividend, combination, recapitalization or reclassification, the number of shares reserved under the 2007 Plan and the number of shares and exercise price, if applicable, of all outstanding stock awards will be appropriately adjusted.

Change in Control. In the event of a change in control of us, the Administrator may take one or more of the following actions without the consent of any 2007 Plan participant or stockholder of ours:

•

arrange for all outstanding stock awards under the 2007 Plan to be assumed, continued or substituted for by any entity surviving the change in control;

•

accelerate in part or in full the vesting provisions of stock awards held by participants;

•

arrange or otherwise provide for the payment of cash or other consideration to participants in exchange for the satisfaction or cancellation of such stock awards; or

•

generally make such other modifications, adjustments or amendments to outstanding awards or the 2007 Plan as the Administrator deems necessary or appropriate.

In the event that an award outstanding under the 2007 Plan is not exercised in full prior to consummation of a change in control in which the award is not being assumed, continued or substituted for, the award shall automatically terminate as of immediately prior to the consummation of the transaction. In addition, the 2007 Plan provides that in the event a participant is involuntarily terminated in connection with, or within twelve months after, a change in control of us, each of the participant’s stock awards outstanding under the 2007 Plan that are assumed, continued or substituted for by a surviving entity in connection with the change in control will become fully vested.

Involuntary termination includes (i) a discharge without cause, or (ii) voluntary resignation by the participant within sixty days following a material reduction in the participant’s job responsibilities, an involuntary relocation of participant’s work site to a location more than fifty miles from the participant’s work site as of immediately prior to the change in control or a material reduction in the participant’s total compensation other than as part of a reduction by the same percentage amount of the compensation of all other similarly-situated employees. A change in control generally includes:

•

a merger or consolidation of us after which our own stockholders as of immediately prior to the merger or consolidation own 50% or less of the surviving entity;

•

a sale of all or substantially all of our assets;

•

a complete liquidation or dissolution of us; or

•

an acquisition of 50% or more of our outstanding stock by any person or group.

Plan Amendments. Our Board will have the authority to amend or terminate the 2007 Plan. However, no amendment or termination of the plan will adversely affect any rights under outstanding awards unless agreed to in writing by the affected participant. We will obtain stockholder approval of any amendments to the 2007 Plan as required by applicable law.

CEO and Executive Officer Equity Award Compensation Policy

In May 2007, our Board adopted our Equity Award Compensation Policy, which was most recently amended effective January 4, 2008. Under the Equity Award Compensation Policy, our Chief Executive Officer and other executive officers designated by our Compensation Committee are eligible to receive an annual non-qualified stock option grant. Generally an executive officer is first eligible to receive an annual grant once the executive first becomes vested as to at least 60% of the first option grant the executive receives from us. Once eligible, our Chief Executive Officer will receive an annual option grant to purchase an aggregate of 300,000 shares of common stock and our other executive officers may receive an annual option grant to purchase the number of shares of common stock approved by our Compensation Committee at the time of grant. The specific amount of the stock option for each named executive officer other than our Chief Executive Officer is based on a subjective assessment by the Compensation Committee of the extent to which the stock options will further our company’s goals of retaining executives and motivating the executives to achieve strong long-term performance. In connection with this determination, the Compensation Committee also takes prior year grant levels and individual roles and responsibilities when determining the specific amount of the option award values to be awarded to each of the other named executive officers. All options granted under the Equity Award Compensation Policy will have an exercise price equal to the fair market value of our common stock on the date of grant and vest at a rate of 20% per year over five years. Messrs. Kiani, de Raad, Fishel and Lee received a stock option grant pursuant to the policy in January 2009, February 2010 and February 2011. See “—Components of our Compensation Approach—Equity Based Incentives” above.

Accrued Vacation Payout Policy

In 2008, our Compensation Committee adopted an accrued vacation payout policy. Under the policy, all employees are eligible to accrue vacation up to an amount equal to two times their annual vacation accrual rate. For example, an employee who accrues three weeks of vacation per year is eligible to accrue up to six weeks of accrued vacation under the policy. At the time the policy was adopted, if any employee had accrued vacation in an amount equal to greater than the amount of vacation the employee accrued on an annual basis, then we paid the employee cash consideration for the full amount of accrued vacation above the employee’s annual accrued vacation rate. The policy applies equally to all of our employees and is designed to help us manage our vacation accrual exposure.

2007 Severance Protection Plan

Our Board adopted the 2007 Severance Protection Plan (the “Severance Plan”) which covers four of our named executive officers. The Severance Plan became effective on July 19, 2007, and was amended effective December 31, 2008. The purpose of the Severance Plan is to treat employees who are terminated in a fair and compassionate manner by mitigating the adverse financial effects of such termination. Messrs. Allan, Coleman, de Raad, Fishel, Jansen, Lee and Sampath participate in the Severance Plan and have entered into severance agreements with us, which are referred to as the “Severance Agreements.”

Administration. The Severance Plan is administered by the Compensation Committee of our Board, unless the Board designates another committee or other persons to administer the Severance Plan. Subject to the terms and conditions of the Severance Plan, the administrator of the Severance Plan referred to as the “Plan Administrator,” has full authority necessary for the general administration and management of the Severance Plan, including full discretion to select individuals who shall be eligible to participate in the Severance Plan, to interpret, construe and apply the provisions of the Severance Plan and the Severance Agreements and to determine all questions relating to eligibility for benefits under the Severance Plan and the Severance Agreements. Subject to certain limitations upon a change in our control, the Executive Annual Plan Administrator also has authority to amend the Severance Plan, extend the term of the Severance Plan and terminate the Severance Plan prospectively.

Severance Benefits. Pursuant to the Severance Plan and their Severance Agreements, Messrs. de Raad, Fishel and Lee may be eligible to receive either basic severance benefits or change in control severance benefits, but not both, and Messrs. Allan, Coleman, Jansen and Sampath may be eligible to receive only change in control severance benefits.

Basic Severance Benefits. In order for Messrs. de Raad, Fishel and Lee to be eligible to receive basic severance benefits under their Severance Agreements, the following conditions must be met:

•

the executive must execute a general release of claims, a non-disparagement agreement, an intellectual property nondisclosure agreement and a non-competition agreement that covers the period during which the executive is receiving severance benefits under the Severance Plan and his Severance Agreement, as well as any other documentation required by the Executive Annual Plan Administrator;

•

the executive must not have received any change in control severance benefits under the Severance Plan or his Severance Agreement, or any severance benefits equal to or better than the basic severance benefits pursuant to another arrangement between the executive and us; and

•

the executive must waive any and all rights, benefits and privileges to severance benefits that he might otherwise be entitled to receive under any other oral or written plan, employment agreement or arrangement with us.

In the event Mr. de Raad, Mr. Fishel or Mr. Lee is entitled to receive basic severance benefits under the Severance Plan and his Severance Agreement:

•

the executive will receive an amount equal to his annual salary determined at the highest rate in effect during the one-year period immediately prior to the date of his termination, which will be paid by us in monthly installments according to our normal payroll practices over the one-year period following his termination;

•

the executive and his qualifying beneficiaries will receive COBRA continuation coverage at our expense during the 12-month period following his termination; and

•

the executive will receive the right to purchase life insurance through us for the 12-month period following his termination.

However, in the event Mr. de Raad, Mr. Fishel or Mr. Lee commences new employment during the one-year period following his termination, any income or benefits he receives from his new employment will reduce (on a dollar-for-dollar basis) the basic severance benefits payable by us under the Severance Plan and his Severance Agreement from the date his new employment commences.

Change in Control Severance Benefits. In order for a Severance Plan participant to be eligible to receive change in control severance benefits under his Severance Agreement, the following conditions must be met:

•

for Messrs. de Raad, Fishel and Lee, during the period commencing upon a change in control and ending on the 36-month anniversary of the change in control, the executive must have a covered termination, which means that either (i) the executive must terminate his employment with us (or our successor) for good reason within two years following the initial existence of an event or circumstance that constitutes good reason, or (ii) we (or our successor) must terminate the executive’s employment without cause (a “Covered Termination”);

•

for Messrs. Allan, Coleman, Jansen and Sampath, either (i) the executive’s employment terminates upon a change in control because his then-current job or a similar job is not offered to the executive on the date of the change in control, or (ii) the executive has a Covered Termination on or after a change in control for any reason other than as set forth in clause (i);

•

for all executives, the executive must execute a mutual release of claims, a non-disparagement agreement, an intellectual property nondisclosure agreement and a non-competition agreement that covers the period during which the executive is receiving severance benefits under the Severance Plan and his Severance Agreement, as well as any other documentation required by the Plan Administrator;

•

for all executives, the executive must not have received any basic severance benefits under the Severance Plan or his Severance Agreement, or any severance benefits equal to or better than the change in control severance benefits pursuant to an arrangement between the executive and us; and

•

for all executives, the executive must waive any and all rights, benefits and privileges to severance benefits that he might otherwise be entitled to receive under any other oral or written plan, employment agreement or arrangement with us.

In the event Mr. de Raad, Mr. Fishel or Mr. Lee is entitled to receive change in control severance benefits under the Severance Plan and his Severance Agreement, the executive will receive the following:

•

if the executive has a Covered Termination because his job as of the date of his Severance Agreement is not offered to him on the date of the change in control, the executive will receive (i) an amount equal to his annual salary determined at the highest rate in effect during the one-year period immediately prior to the date of the Covered Termination, plus the executive’s average annual bonus over the three-year period prior to the change in control, and (ii) the right to purchase life insurance through us for the 12-month period following his termination; or if the executive has a Covered Termination for any other reason, the executive will receive (a) an amount equal to two times his annual salary determined at the highest rate in effect during the one-year period immediately prior to the date of the Covered Termination, plus the executive’s average annual bonus over the three-year period prior to the change in control, and (b) life insurance paid by us for the 12-month period following his termination; and

•

the executive and his qualifying beneficiaries will receive COBRA continuation coverage at our expense during the 12-month period following his termination.

In addition, upon any change in control, 50% of Mr. de Raad’s, 50% of Mr. Fishel’s and 50% of Mr. Lee’s unvested stock options and other equity-based awards shall be fully accelerated as of the change in control and 100% of the executive’s unvested stock options and other equity-based awards shall be fully accelerated upon the executive’s termination in the event he becomes entitled to the change in control severance benefits above as a result of a Covered Termination. Change in control severance amounts payable to Mr. de Raad, Mr. Fishel and

Mr. Lee will be made in a lump sum cash payment within 30 days following the date the executive has met all of the conditions for his change in control severance, provided that in no event will the cash portion of the executive’s change in control severance be payable more than two and one-half months after the end of the calendar year in which the termination occurs.

In the event Mr. Allan, Mr. Coleman, Mr. Jansen or Mr. Sampath is entitled to receive change in control severance benefits under the Severance Plan and his Severance Agreement, 50% of the executive’s unvested stock options and other equity-based awards shall be fully accelerated as of a change in control.

The Plan Administrator has the right to reduce any change in control severance benefits payable to an executive to avoid triggering any “excess parachute payments” under Section 280G of the Code. In addition, the Plan Administrator may delay the payment or issuance of any severance or change in control severance benefits for up to six months as necessary to avoid the imposition of additional tax under Section 409A of the Code.

For purposes of the Severance Plan and the Severance Agreements:

•

“cause” generally means: (i) the refusal or failure by the executive to perform his duties with us or to comply in all respects with our policies or the policies of any affiliate of ours after notice of a deficiency and the executive’s failure to cure the deficiency within three business days following notice from us, unless the executive has delivered a bona fide notice of his termination for good reason to us, and the reason for the executive’s termination has not been cured by us within 30 days of receipt of notice; (ii) the executive’s engagement in illegal or unethical conduct that could be injurious to us or our affiliates; (iii) the executive’s commitment of one or more acts of dishonesty; (iv) the executive’s failure to follow a lawful directive from our chief executive officer; or (v) the executive’s indictment of any felony, or any misdemeanor involving dishonesty or moral turpitude.

•

“change in control” generally means: (i) a merger or consolidation of us, or a sale of all or substantially all of our assets unless more than 50% of the voting securities of the surviving or acquiring entity are held by our stockholders as of immediately prior to the transaction; (ii) the approval by our stockholders of the sale of all or substantially all of our assets; or (iii) without the prior approval of our Board, the acquisition by any person or group of securities representing beneficial ownership of 50% or more of our outstanding voting securities.

•

“good reason” generally means, provided that the executive has provided us with notice of one of the following events within 15 days after it occurs and we fail to cure the event within 30 days after receiving notice from the executive: (i) any material reduction by us in the executive’s annual salary; (ii) any requirement that the executive change his principal location of work to any location that is more than 40 miles from the address of our current principal executive offices; or (iii) any material change in the executive’s responsibilities.

Voluntary Resignation. Excluding a resignation for good reason during the period commencing upon a change in control and ending on the 36-month anniversary of the change in control, in the event a Severance Plan participant wishes to voluntarily resign from his employment at any time during which the Severance Plan and his Severance Agreement are effective, he has agreed to provide us with six months advance notice of his resignation.

Agreement Termination. A Severance Plan participant’s Severance Agreement will terminate upon his termination for any reason that does not constitute a termination entitling him to basic or change in control severance benefits or if we terminate the Severance Plan in our role as the Severance Plan sponsor prior to the time he becomes entitled to any severance under the Severance Plan and his Severance Agreement.

Potential Payments upon Termination or Change in Control

The tables below estimate amounts of (i) salary and benefits payable, and (ii) the acceleration of options outstanding for each of our named executive officers, in each case assuming that a change in control, termination of employment or both occurred on December 31, 2010. The closing price of our common stock, as reported on the Nasdaq Global Market, was $29.07 on December 31, 2010. The following tables assume that:

•

Mr. Allan’s severance benefits are derived from his severance agreement with us;

Masimo Retirement Savings Plan

We maintain a retirement savings plan, referred to as the “Savings Plan,” which is intended to be a tax-qualified retirement plan. All of our employees age 18 and older are eligible to participate in the Savings Plan. Participants may elect to defer a percentage of their eligible pretax earnings each year up to the maximum contribution permitted by the Code. Each participant’s interests in his or her deferrals are 100% vested when contributed. The Savings Plan permits us to make matching contributions if we choose and we have historically provided matching contributions of up to three percent, subject to a maximum amount. In the event the employee is employed with us for less than two years, we do not provide a matching contribution. In the event the employee is employed with us for two or more years, but less than three years, we provide a matching contribution at a 50% level. In the event the employee is employed with us for three or more years, but less than four years, we provide a matching contribution at a 75% level. In the event the employee is employed with us for

four or more years, we provide a matching contribution at a 100% level. Effective February 15, 2008, participants in our Savings Plan were eligible to direct some or all of their contributions, as well as our matching contributions, to the purchase of shares of our common stock through the plan. The Savings Plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As such, contributions to the Savings Plan and earnings on those contributions are not taxable to participants until distributed from the Savings Plan, and all contributions are deductible by us when made.

Non-Employee Director Compensation

We have adopted a non-employee director compensation policy, which was most recently amended effective December 15, 2008. Under this policy, our Audit Committee chairperson receives an annual cash retainer of $40,000, payable on a quarterly basis in arrears. Except as otherwise provided by our Board or compensation committee, no other non-employee director is entitled to receive any cash compensation for his service on our Board or any committee thereof. However, our non-employee directors are entitled to reimbursement for their reasonable expenses incurred in connection with attending meetings of our Board and committees thereof and performing their functions and duties as directors.

Our Board has adopted the following policy with respect to granting stock options to non-employee directors. Our Audit Committee chairperson received a stock option grant for 150,000 shares of common stock, which vests at a rate of 20% per year. Upon first becoming a member of our Board of Directors, unless otherwise determined by our Compensation Committee, each non-employee director other than our Audit Committee chairperson receives a stock option grant to purchase 50,000 to 100,000 shares of our common stock that vests at a rate of 20% per year on each anniversary of the grant date. Our Compensation Committee will determine the size of the award to be made. Upon the vesting of 60% of the initial option award to our Audit Committee chairperson and other outside directors, our Compensation Committee will provide our Audit Committee chairperson or other non-employee director, as applicable, an additional annual option grant to purchase 20,000 shares of our common stock that vest at a rate of 20% per year on each anniversary of the grant date.

Through February 28, 2011, we granted to our current non-employee directors options to purchase an aggregate of 1,515,000 shares of common stock under our 1996 Plan, 2004 Plan and 2007 Plan. In the year ended January 1, 2011, we granted to our non-employee directors options to purchase an aggregate of 80,000 shares of our common stock under our 2007 Plan. All awards made to our non-employee directors in the future will be made under our 2007 Plan or a successor plan. For a more detailed description of this plan, see “Compensation of Executive Officers—Employee Benefit Plans—2007 Stock Incentive Plan.” We did not grant any type of equity award other than stock options to our non-employee directors during the year ended January 1, 2011. Our Audit Committee chairperson was the only non-employee director who received cash compensation for his Board and committee service in fiscal 2010.

The following table sets forth summary information concerning compensation paid or accrued for services rendered to us in all capacities to the members of our Board of Directors for the fiscal year ended January 1, 2011.


Name⁽¹⁾⁽²⁾	Fees Earned or Paid in Cash			Option Awards⁽³⁾		All Other Compensation		Total

Jack Lasersohn		—			218,918		—		218,918

⁽¹⁾	Joe Kiani, our Chairman and Chief Executive Officer and a named executive officer, is not included in this table as he is an employee of ours and therefore receives no compensation for his service as a director. Mr. Kiani’s compensation is included in the “Summary Compensation Table” above.

⁽²⁾	As of January 1, 2011, each of our non-employee directors held the following number of options: Steven J. Barker, M.D., Ph.D.—170,000; Edward L. Cahill—40,000; Robert Coleman, Ph.D.—159,400; Sanford Fitch—110,000; and Jack Lasersohn—70,000.

⁽³⁾

These amounts represent the aggregate grant date fair value of awards for grants of options to each listed director in fiscal 2010, computed in accordance with authoritative accounting guidance. These amounts do not represent the actual amounts paid to or realized by the directors during fiscal 2010. The value as of the grant date for stock options is recognized over the number of days of service required for the stock option to vest in full. For a detailed description of the assumptions used for purposes of determining grant date fair value, see Note 11 to the Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates—Share-Based Payment,” included in our Annual Report on Form 10-K for the year ended January 1, 2011.

⁽²⁾

Comprised solely of shares subject to awards available for future issuance under the 2007 Plan. Pursuant to the terms of the 2007 Plan, the share reserve of the 2007 Plan will automatically increase on the first day of each fiscal year, through fiscal 2017, by three percent of the aggregate number of shares of our common stock outstanding as of the last day of the immediately preceding fiscal year, or such lesser amount, including zero, determined by our Board of Directors or our Compensation Committee prior to the commencement of the fiscal year.

⁽³⁾	As of January 1, 2011, we did not have any equity compensation plans that were not approved by our stockholders.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information as of February 28, 2011, with respect to the beneficial ownership of shares of our common stock by:

•

each person or group known to us to be the beneficial owner of more than five percent of our common stock;

•

each of our directors;

•

each of our named executive officers; and

•

all of our current directors and executive officers as a group.

This table is based upon information supplied by officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Other than as set forth below, we are not aware of any other beneficial owner of more than five percent of our common stock as of February 28, 2011. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community property laws.

Applicable percentage ownership is based on 59,636,534 shares of common stock outstanding as of February 28, 2011, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options that are either immediately exercisable or exercisable on or before April 29, 2011, which is 60 days after February 28, 2011. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Masimo Corporation, 40 Parker, Irvine, California 92618.

⁽¹⁾

For each person and group included in this table, percentage ownership is calculated by dividing the number of shares beneficially owned by such person or group by the sum of 59,636,534 shares of common stock outstanding as of February 28, 2011, plus the number of shares of common stock that such person or group had the right to acquire within 60 days after February 28, 2011.

PROPOSAL NO. 2

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee of our Board of Directors has selected Grant Thornton LLP (“Grant Thornton”) as our independent auditors for the fiscal year ending December 31, 2011, and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the Annual Meeting.

Grant Thornton was appointed as our independent auditors in July 2006 and has reported on our consolidated financial statements as of and for the years ended December 31, 2005, December 31, 2006, December 29, 2007, January 3, 2009, January 2, 2010 and January 1, 2011. The decision to select Grant Thornton as our independent auditors for the fiscal year ending December 31, 2011 was recommended by our Audit Committee and approved by our Board of Directors.

Representatives of Grant Thornton are expected to be present at the Annual Meeting. The representatives of Grant Thornton will be able to make a statement at the meeting if they wish and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require that our stockholders ratify the selection of Grant Thornton as our independent auditors. However, the Audit Committee is submitting the selection of Grant Thornton to the stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of Masimo and our stockholders.

Although our stockholders are not required ratify the selection of Grant Thornton as our independent auditors, because we have submitted the ratification of our auditors for approval by stockholders, the affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the Annual Meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) will be required to ratify the selection of Grant Thornton as our independent auditors for the fiscal year ending December 31, 2011.

Principal Accountant Fees and Services

The following table represents aggregate fees billed to Masimo for the fiscal years ended January 1, 2011 and January 2, 2010 by Grant Thornton, our principal auditors for such periods. All fees described below were approved by the Audit Committee.


	Fiscal Year Ended
	January 1, 2011		January 2, 2010
Audit Fees ⁽¹⁾	$	1,424,875	$	1,421,077
Audit-Related Fees ⁽²⁾		—		10,362
Tax Fees ⁽³⁾		136,728		199,468
All Other Fees		—		—

Total Fees	$	1,561,603	$	1,630,907

⁽¹⁾

Audit fees consist of fees billed for services rendered for the audit of our consolidated annual financial statements, including performance of the attestation procedures required by Section 404 of the Sarbanes-Oxley Act of 2002, review of the interim consolidated financial statements included in quarterly reports and services that are normally provided by Grant Thornton in connection with statutory and regulatory filings or engagements. Audit fees also consist of fees for services associated with SEC registration statements, including our “shelf” registration statement on Form S-3 and our registration statements on Form S-8 in connection with our stock incentive plan and retirement savings plan, and other documents filed with the SEC.

⁽²⁾

Audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of the audit or review of our interim consolidated financial statements and not reported under the caption “Audit Fees.” For the fiscal year ended January 2, 2010, these services included consultation services related to the impact of future accounting pronouncements on our consolidated financial statements.

⁽³⁾	Tax fees consist of fees for preparation of our federal and state income tax returns, general consultation and international tax research.

Audit Committee’s Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy for the pre-approval of audit and non-audit services rendered by our independent auditors, Grant Thornton. The policy 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 auditors or on an individual explicit case-by-case basis before the independent auditors are 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. By the adoption of this policy, the Audit Committee has delegated the authority to pre-approve services to the Chairperson of the Audit Committee, subject to certain limitations.

The Audit Committee has determined that the rendering of the services other than audit services by Grant Thornton is compatible with maintaining the principal accountant’s independence.

In accordance with Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), we are providing our stockholders the opportunity to vote on a non-binding, advisory resolution to approve the compensation of our named executive officers, which is described in this Proxy Statement in the section titled “Compensation Discussion and Analysis” beginning on page 23, and the compensation tables beginning on page 34, and any related narrative discussion contained in this Proxy Statement.

The Company’s executive compensation program is designed to attract, retain and motivate the best possible executive talent. The focus is to tie short and long-term cash and equity incentives to the achievement of measurable corporate objectives and to align executives’ incentives with stockholder value creation. To achieve these objectives, the Compensation Committee has adopted a compensation approach that ties a substantial portion of executives’ overall compensation to our operational performance.

In fiscal 2010, although significant components of the Company’s end user marketplace were still struggling to recover from the economic recession in 2008 and 2009, the Company was able to achieve a number of remarkable milestones, including that we:

•

Delivered on our key financial targets, including record product revenues of $356.4 million, up 18.8% from 2009 and total revenues of $405.4 million, up 16.1%. We also met our GAAP earnings per share targets as our GAAP EPS rose 37.5% to $1.21 per share or, excluding one-time items, rose 17.1% to $1.03.

•

Shipped a record 153,200 Masimo SET and Masimo rainbow SET units – up 37.5% from the prior year.

•

Achieved a variety of other non-financial targets, including volumes of driver and sensor shipments, various quality initiatives and new product introductions.

As a result of these achievements, the Compensation Committee believes that the compensation plans and objectives are appropriately incentivizing the members of the executive management team and that the plans in place will be sufficient to continue to incentivize the entire management team going forward.

Stockholders are urged to read the Compensation Discussion and Analysis section of this Proxy Statement, which more thoroughly discusses how our compensation policies and procedures implement our compensation philosophy. The Compensation Committee and the Board believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving its goals.

In light of the above, we believe that the compensation of our named executive officers for fiscal 2010 was appropriate and reasonable, and that our compensation policies and procedures are sound and in our best interests and in the best interests of our stockholders.

Accordingly, the following resolution will be submitted for a stockholder vote at the Annual Meeting:

“RESOLVED, that the stockholders of Masimo Corporation approve, on an advisory and non-binding basis, the compensation of the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, in this Proxy Statement.”

While this stockholder vote on executive compensation is merely advisory and will not be binding upon us or the Board or our Compensation Committee, we value the opinions of our stockholders and will consider the outcome of the vote when making future compensation decisions.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DESCRIBED IN THIS PROXY STATEMENT

PROPOSAL NO. 4

ADVISORY VOTE TO APPROVE THE FREQUENCY WITH WHICH EXECUTIVE COMPENSATION WILL BE SUBJECT TO A STOCKHOLDER ADVISORY VOTE

In accordance with Section 951 of the Dodd-Frank Act, we are providing our stockholders the opportunity to cast an advisory vote on whether a non-binding stockholder resolution to approve the compensation of our named executive officers should occur every one, two or three years. The Board recommends that stockholders vote to hold an advisory vote on executive compensation every three years, or a triennial vote.

The Board believes that a triennial vote complements our goal of tying short and long-term cash and equity incentives to the achievement of measurable corporate objectives and to align executives’ incentives with stockholder value creation. As described in the section titled “Compensation Discussion and Analysis,” our executive compensation program is designed to attract, retain and motivate the best possible executive talent. To facilitate the creation of long-term, sustainable stockholder value, certain of our compensation awards are contingent upon successful completion of multi-year performance and service periods. A triennial vote will provide stockholders the ability to evaluate our compensation program over a time period similar to the periods associated with our compensation awards, allowing them to compare the Company’s compensation program to the long-term performance of the Company.

Additionally, a triennial vote will provide us with the time to thoughtfully respond to input from our stockholders. We carefully review changes to our executive compensation program to ensure that the program appropriately aligns our named executive officers’ interests with the long-term interests of our stockholders and to ensure that the program appropriately balances risk and reward. We therefore believe that a vote every three years is an appropriate frequency to provide sufficient time to thoughtfully consider stockholders’ input and to implement any appropriate changes to our executive compensation program, in light of the timing that would be required to implement any decisions related to such changes.

The voting frequency option that receives the highest number of votes cast by stockholders will be the frequency for the advisory vote on executive compensation that has been selected by stockholders. However, because this vote is advisory and not binding on the Board or the Company, the Board may decide that it is in the best interests of our stockholders and the Company to hold an advisory vote on executive compensation more or less frequently than the option approved by our stockholders.

THE BOARD OF DIRECTORS RECOMMENDS

THAT STOCKHOLDERS VOTE FOR A FREQUENCY PERIOD OF EVERY “3 YEARS” (A TRIENNIAL VOTE) FOR FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION

PROPOSAL NO. 5

STOCKHOLDER PROPOSAL

We have been advised that California State Teachers’ Retirement System (“CalSTRS”) Investments, 100 Waterfront Place, MS-04, West Sacramento, California 95606-2807, a beneficial owner of shares of our common stock having a market value in excess of $2,000, intends to submit the proposal set forth below at the Annual Meeting.

BE IT RESOLVED: That the stockholders of Masimo Corporation hereby request that the Board of Directors initiate the appropriate process to amend the Company’s certificate of incorporation and/or bylaws to provide that director nominees shall be elected by the affirmative vote of the majority of votes cast at an annual meeting of stockholders, with a plurality vote standard retained for contested director elections, that is, when the number of director nominees exceeds the number of board seats.

SUPPORTING STATEMENT:

In order to provide stockholders a meaningful role in director elections, the Company’s current director election standard should be changed from a plurality vote standard to a majority vote standard. The majority vote standard is the most appropriate voting standard for director elections where only board nominated candidates are on the ballot, and it will establish a challenging vote standard for board nominees to improve the performance of individual directors and entire boards. Under the Company’s current voting system, a nominee for the board can be elected with as little as a single affirmative vote, because “withheld” votes have no legal effect. A majority vote standard would require that a nominee receive a majority of the votes cast in order to be re-elected and continue to serve as a representative for the stockholders.

In response to strong stockholder support a substantial number of the nation’s leading companies have adopted a majority vote standard in company bylaws or certificate of incorporation. In fact, more than 68% of the companies in the S&P 500 have adopted majority voting for uncontested elections. We believe the Company needs to join the growing list of companies that have already adopted this standard.

CalSTRS is a long-term stockholder of the Company and we believe that accountability is of upmost importance. We believe the plurality vote standard currently in place at the Company completely disenfranchises stockholders and makes the stockholder’s role in director elections meaningless. Majority voting in director elections will empower stockholders with the ability to remove poorly performing directors and increase the directors’ accountability to the owners of the Company, its stockholders. In addition, those directors who receive the majority support from stockholders will know they have the backing of the very stockholders they represent. We therefore ask you to join us in requesting that the Board of directors promptly adopt the majority vote standard for director elections. Please vote FOR this proposal.

Management’s Statement Against the Proposal to Adopt a Majority Vote Standard for Director Elections

The Board believes that this proposal is not in the best interests of the Company or its stockholders, and recommends that you vote against the proposal.

The proposal requests that we adopt a majority voting standard for director elections. Our directors are currently elected by a “plurality” vote standard, meaning that those nominees for election to the Board that receive the greatest number of votes are elected. We believe that our stockholders are satisfied with the composition of our Board, as our stockholders have a history of electing a strong and independent Board, by plurality, and all of our directors have previously been elected by the affirmative vote of substantially more than a majority of our outstanding shares. Plurality voting for director elections is standard under Delaware law, as well as the law of other states, and is used by many of the largest corporations in the U.S., including corporations

that have been recognized as leaders in corporate governance. The rules governing plurality voting are well understood and a plurality voting system does not prevent stockholders from challenging and defeating Board nominees.

Our Board believes that meaningful stockholder participation in the election of directors is important to provide accountability of corporate boards to stockholders and effective corporate governance practices that reflect the highest standards of responsibility, ethics and integrity. Our Board also seeks to ensure that the Company’s director elections are fair, impartial and in the best interests of stockholders. While the concept of majority voting for the election of directors may initially appear straightforward and democratic, there are complex legal and practical issues surrounding the implementation of a majority voting standard that this proposal does not address and that must be resolved before our Board could adopt such a policy. For the following reasons, our Board opposes this stockholder proposal.

Strong existing corporate governance processes

The Board believes that it already has strong corporate governance processes for identifying and proposing director nominees who will serve the best interests of the Company and its stockholders. The Board maintains a Nominating and Corporate Governance Committee that is composed entirely of independent directors, and all of the members of the Board are independent under the rules of the Nasdaq Stock Market, LLC, other than our Chief Executive Officer. The Nominating and Corporate Governance Committee applies a strong set of criteria in identifying director nominees and has adopted a policy pursuant to which it considers and evaluates persons recommended by stockholders in the same manner as potential nominees identified by the Company and the Board. The Board believes that its processes for identifying and proposing director candidates provide the best foundation for a strong and effective Board and excellence in corporate governance.

Risk of holdover boards and failed elections

This proposal seeks to require that directors be elected by a majority of shares voted at the annual meeting, so that nominees who receive less than a majority of shares voted or withheld would not be elected. However, because Delaware law provides that an elected director serves until a successor is elected to fill his position, it is possible that an incumbent director might not receive a majority vote for that Board seat, but because no other nominee received a majority favorable vote, that director would nevertheless continue to serve on the Board on a “holdover” basis.

Furthermore, this stockholder proposal increases the possibility of failed elections and any absence of a majority vote may create an additional and potentially expensive process in order to replace a vacant Board position. In this circumstance, the incumbent directors would continue to serve, or the holdover Board of Directors could appoint new directors to fill the vacancies. Any such vacant Board position also increases the workload of our existing directors, especially those serving on Board committees.

This proposal is not necessary to create growth in stockholder value

The proponent of this proposal suggests that it is necessary to make the directors more accountable to the stockholders. The Company has adopted corporate governance policies and procedures, consistent with best practices, to increase the transparency and accountability of the Company’s leadership to stockholders. The proponent also suggests that adopting this proposal will enhance company performance. We certainly agree that strong corporate governance practices benefit stockholders, but we do not believe that this proposal will improve the Company’s corporate governance or lead to better performance. This is consistent with our view that adopting this proposal would not enhance our corporate governance practices and instead could distract our management and the Board and use corporate resources at a time when they would be better invested in other areas.

Certain organizations are currently evaluating the feasibility and implications of adoption of a majority voting standard. These groups are considering, among other things, whether changes in the corporate laws of Delaware are necessary in connection with any shift to majority voting for directors and how best to address any resulting practical difficulties for companies relating to compliance with current proposed rules and regulations of the SEC and Nasdaq corporate governance rules. Stockholder advocates and advisors on corporate governance have proposed varying policies. The Board will continue to monitor closely the progress of these discussions and, once the issues surrounding majority voting are resolved, the Board and its committees will take appropriate action to maintain the Company’s commitment to the highest standards of corporate governance. The Board believes that adoption of a majority voting standard now would be premature and would not serve the best interests of the Company’s stockholders, particularly in light of the fact that the proposal does not address the legal and practical issues of changing long-standing, successful voting procedures.

For the foregoing reasons,

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE AGAINST THE STOCKHOLDER PROPOSAL TO ADOPT A MAJORITY VOTING STANDARD FOR DIRECTOR ELECTIONS

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who beneficially own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes of ownership of common stock and our other equity securities. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended January 1, 2011, our officers, directors and greater than ten percent beneficial owners complied with all Section 16(a) filing requirements applicable to them, except that Drs. Barker and Coleman and Messrs. Kiani, de Raad, Fishel, Lee, Cahill and Lasersohn each did not timely file one report with respect to the receipt of a single option grant.

TRANSACTIONS WITH RELATED PERSONS, PROMOTERS AND CERTAIN CONTROL PERSONS

Related Person Transactions Policy and Procedures

In March 2008, we adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration and approval or ratification of transactions with related persons. For purposes of our policy only, a “related person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we (including any of our subsidiaries) and any “related person” were, are or will be participants involving an amount that exceeds $120,000. For purposes of the policy, a related person is:

•

any person who is or was a director or executive of ours since the beginning of our immediately preceding fiscal year or an immediate family member of, or person sharing a household with, any of the foregoing individuals;

•

any person known by us to be the beneficial owner of more than five percent of the outstanding voting securities or, if the beneficial owner is an individual, an immediate family member of, or person sharing a household with, any of the foregoing individuals; and

•

any firm, corporation or other entity in which any of the foregoing individuals is employed or is a general partner or principal or in a similar position, or in which any of the foregoing individuals has a five percent or greater beneficial interest.

Under the policy, prior to entering into a related person transaction, our legal department must present information regarding the proposed related person transaction to our Nominating and Corporate Governance Committee for approval at its next regularly scheduled meeting (or, where our legal department, in consultation with our Chief Executive Officer or Chief Financial Officer, determines that it is not practicable to or desirable to wait until the next meeting of the Nominating and Corporate Governance Committee, to the Chairperson of our Nominating and Corporate Governance Committee, who is authorized under the policy to act on behalf of the Nominating and Corporate Governance Committee with respect to matters covered by the policy between meetings of the Nominating and Corporate Governance Committee). The presentation must include:

•

a description of the related person’s relationship to us and interest in the related person transaction;

•

the material terms of the proposed related person transaction;

•

the perceived benefits to us of the proposed related person transaction;

•

if applicable, the availability to us of other sources for comparable products or services subject to the proposed related person transaction; and

•

an assessment of whether the proposed related person transaction is on terms that are comparable to the terms available to or from, as applicable, a third party that is not a related person or to our employees generally.

To identify proposed related person transactions in advance, our legal department relies on information supplied by our directors, executive officers or our business unit or function/department leader responsible for the proposed related person transaction. In considering related person transactions, the Nominating and Corporate Governance Committee takes into account all relevant facts and circumstances related to the proposed transaction including, but not limited to the information discussed above and, in the event the related person is a director or an immediate family member or affiliate of a director, the impact of the proposed related person transaction on the director’s independence. In the event a member of the Nominating and Corporate Governance Committee, or any immediate family member or affiliate of a member of the Nominating and Corporate Governance Committee is the related person, the Nominating and Corporate Governance Committee person is prohibiting from participating in any review, consideration or approval of the related person transaction. The policy requires that the Nominating and Corporate Governance Committee shall only approve a related person transaction if it determines in good faith that the transaction is in, or is not inconsistent with, our best interests and the best interests of our stockholders.

Under the policy, the following related person transactions are deemed to be pre-approved by the Nominating and Corporate Governance Committee regardless of the amount involved:

•

employment and compensation of our executive officers, subject to certain exceptions;

•

compensation of our directors, subject to certain exceptions;

•

certain transactions between us and an unrelated third party entity in which the related person’s only relationship with the third party is as an employee (other than an executive officer), director or beneficial owner of less than 10% of the other entity’s shares, subject to certain limitations;

•

certain charitable contributions; and

•

transactions in which all of our security holders receive the same benefit on a pro rata basis.

The policy also permits our Nominating and Corporate Governance Committee to ratify, amend, rescind or terminate any related person transaction that is not pre-approved in accordance with the terms above.

Transactions with Related Persons

The following is a description of transactions or series of transactions since January 3, 2010, or any currently proposed transaction, to which we were or are to be a participant in which the amount involved in the transaction or series of transactions exceeds $120,000, and in which any of our directors, executive officers or persons who we know held more than five percent of any class of our capital stock, including their immediate family members, had or will have a direct or indirect material interest, other than compensation arrangements that are described under “—Employment Agreement and Offer Letters” above.

Severance Plan

On May 17, 2010, we entered into a severance agreement pursuant to the Severance Plan with Mr. Allan. See the section entitled “Compensation of Executive Officers—2007 Severance Protection Plan” above.

Stock Option Grants

We have granted stock options to our directors and executive officers. For a description of the options granted in 2010, see the sections entitled “Compensation of Executive Officers—Grants of Plan-Based Awards During Fiscal Year 2010,” “Compensation of Executive Officers—Outstanding Equity Awards at January 1, 2011” and “Compensation of Executive Officers—Non-Employee Director Compensation” above.

On February 22, 2011, we granted the following options to our executive officers and directors:

Steven J. Barker, M.D., Ph.D.		20,000

Cercacor Laboratories, Inc.

Cercacor Laboratories, Inc. (f/k/a Masimo Laboratories, Inc.) (“Cercacor”) is an independent entity spun off from us to our stockholders in 1998. Joe Kiani and Jack Lasersohn, members of our Board, are also members of the board of directors of Cercacor. Joe Kiani, our Chairman and Chief Executive Officer, is also the Chairman and Chief Executive Officer of Cercacor. We are a party to a cross-licensing agreement with Cercacor, which was amended and restated effective January 1, 2007 (the “Cross-Licensing Agreement”), that governs each party’s rights to certain of the intellectual property held by the two companies. Pursuant to the Cross-Licensing Agreement, from January 3, 2010 through February 28, 2011, we paid Cercacor $5.8 million in royalty payments. In addition, to accelerate the product development of Masimo’s total hemoglobin spot check measurement device, in February 2009, Masimo agreed to fund additional Cercacor engineering expenses. Specifically, these expenses included third party engineering materials and supplies expense as well as 50% of total Cercacor engineering and engineering related payroll expenses from April 2009 until completion of the product development efforts. These expenses totaled $3.0 million from January 3, 2010 through February 28, 2011.

Prior to our initial public offering in August 2007, our stockholders owned approximately 99.9% of the outstanding capital stock of Cercacor, and we believe that as of February 28, 2011, a number of stockholders of Cercacor continued to own shares of our common stock.

Indemnification Agreements with Directors and Executive Officers

We have entered into indemnity agreements with our directors and executive officers under which we agreed to indemnify those individuals under the circumstances and to the extent provided for in the agreements, for expenses, damages, judgments, fines, settlements and any other amounts they may be required to pay in actions, suits or proceedings which they are or may be made a party or threatened to be made a party by reason of their position as a director, officer or other agent of ours, and otherwise to the fullest extent permitted under Delaware law and our bylaws. We also have an insurance policy covering our directors and executive officers with respect to certain liabilities, including liabilities arising under the Securities Act of 1933, as amended, or otherwise. We believe that these provisions and insurance coverage are necessary to attract and retain qualified directors, officers and other key employees.

Registration Rights

Pursuant to our Fifth Amended and Restated Registration Rights Agreement dated September 14, 1999, certain stockholders affiliated with two of our directors, Messrs. Cahill and Lasersohn, have the right in specified circumstances to require us to register their shares under the Securities Act of 1933, as amended, for resale to the public. Generally, we are required to bear all registration and selling expenses incurred in connection with any registration required by these stockholders, other than underwriting discounts and commissions. We are also required to bear the reasonable fees and expenses of one counsel for the selling stockholders in each registration.

HOUSEHOLDING

A copy of our Annual Report on Form 10-K for the fiscal year ended January 1, 2011, which is our 2010 annual report, is being mailed to you along with this Proxy Statement. We are sending only one annual report and proxy statement to “street name” stockholders who share a single address unless we received contrary instructions from any stockholder at that address.
