Item 1.01. Entry into a Material Definitive Agreement.

On September 1, 2007, Masimo Corporation (the “Company”), as a guarantor, entered into a Lease Agreement (the “Lease”) with Industrial Vallera de Mexicali, S.A. de C.V. (“IVMSA”) and Industrias Asociadas Maquiladoras, S.A. de C.V. (“IAMSA”) for certain property located in Mexicali, Mexico. The Company serves as a guarantor of IVMSA’s obligations under the Lease. The Lease supersedes three prior lease agreements among the Company, IVMSA and IAMSA for sections of the same property and increases the total amount of leased space.

The Lease covers approximately 95,600 square feet of space in Mexicali, Mexico, for the manufacture of the Company’s sensors and accessories under a shelter labor agreement with IVMSA. IVMSA is a Mexican maquiladora, which is a shelter services provider incorporated in Mexico that is licensed to operate factories and plants in Mexico. The shelter program allows foreign companies to manufacture in Mexico without being required to organize and operate their own subsidiary, for example, as a Mexican corporation. The Company entered into the agreement with IVMSA to establish and run a facility to manufacture its sensors and accessory products. IVMSA leases the space directly from the owner of the property, IAMSA, under the Lease. The Lease has a term of seven years, expiring on September 1, 2014, with an option to extend the Lease for an additional five years.

The foregoing summary of the Lease is qualified in its entirety by reference to the full text of the Lease, which is attached to this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference.
