About Masimo

Masimo (Nasdaq: MASI) develops innovative monitoring technologies that significantly improve patient care-helping solve "unsolvable" problems. In 1995, the company debuted Measure-Through-Motion-and-Low-Perfusion pulse oximetry, known as Masimo SET, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced Masimo Rainbow SET, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Rainbow SET continuously and noninvasively measures total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and PVI(TM), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."

     "Participating Securities and the Two-Class Method under FASB Statement
     No. 128", or EITF 03-6, and SFAS No. 128 "Earnings per Share", or SFAS
     128, in accordance with GAAP and the non-GAAP if-converted method based
     solely upon SFAS No. 128. The non-GAAP if-converted method assumes
     conversion of all shares of our preferred stock into common stock as of
     December 31, 2006.

     Upon closing of the Company's initial public offering on August 13, 2007,
     all of the outstanding convertible preferred shares were converted into
     common shares. Therefore, subsequent to this stock conversion the Company
     uses the if-converted method under SFAS No. 128 to calculate earnings per

     parties to assess our performance on a comparable basis to the three and
