Electronics Manufacturing, a Delaware corporation having its place of business at 615 South River Drive, Tempe, Arizona 85281 (“VEM”) and Masimo Corporation, having its place of business at 2852 Kelvin Avenue, Irvine, CA 92614 (“Customer”).

Customer has created a market for Customer’s Products and is solely responsible for the sales and marketing of the Products. VEM has developed processes and practices for manufacturing products for many different electronic applications and at Customer’s request desires to manufacture Customer’s Products in accordance with Customer’s specifications. Customer acknowledges that VEM’s expertise is manufacturing and that VEM’s responsibility related to the Customer’s Products is limited to this extent. The parties agree as follows:

1.0 WORK, LICENSE

VEM agrees to use reasonable commercial efforts to perform the work (hereinafter “Work”) pursuant to purchase orders or changes thereto issued by Customer and accepted by VEM. Work shall mean to procure labor, components, materials, equipment and other supplies and to manufacture, assemble, and test printed circuit board products more particularly described on Exhibit 1.0 (hereinafter “Products”) pursuant to detailed written specifications for each such Product which are provided by Customer and accepted by VEM and to deliver such Products. For each Product or revision thereof, written specifications shall include but are not limited to bill of materials, designs, schematics, assembly drawings, process documentation, test specifications, current revision number, and approved vendor list (hereinafter “Specifications”).

VEM is granted by Customer a non-exclusive license during the term of this Agreement to use Customer’s patents, trade secrets and other intellectual property as necessary to perform VEM’s obligations under this Agreement.

2.0 FORECASTS, ORDERS, MATERIAL PROCUREMENT

2.1 Forecast. Customer shall provide VEM, on a monthly basis, a rolling six (6) month Product order forecast.

2.2 Purchase Orders. Customer will issue written purchase orders once per calendar month which specify all Work to be completed within a minimum four (4) month period commencing on the date of the purchase order. Each purchase order shall reference this Agreement and the applicable written Specifications as described in Section 1.0. Purchase orders shall normally be deemed accepted by VEM, provided however that VEM may reject any order that represents a significant deviation from Customer’s most recent rolling Product order forecasts for the same time period. VEM shall notify Customer of rejection of any purchase order within five (5) working days of receipt of such order.

Customer may use its standard purchase order form to release items, quantities, prices, schedules, change notices, specifications, or other notice provided for hereunder. The parties agree that the terms and conditions contained in this Agreement shall prevail over any terms and

-1-

conditions of any purchase order, acknowledgment form or other instrument used for ordering Work under this Agreement.

2.3 Material Procurement. Customer’s accepted purchase orders will constitute authorization for VEM to procure, using standard purchasing practices, the labor, and the “Inventory” necessary for the manufacture of Products covered by such purchase orders. The Inventory includes components, materials and supplies.

In addition, Customer authorizes VEM to purchase, components, materials, and supplies: (i) with lead times exceeding the period covered by the accepted purchase orders for the Products to the extent necessary for the manufacture of additional Product covered by the Customer’s forecast (“Long Lead Time Components”) and, (ii) purchased in quantities above the required amount for purchase orders to achieve price targets (“Economic Order Inventory”), and (iii) purchased in excess of requirements for purchase orders because of minimum lot sizes available from manufacturers (“Minimum Order Inventory”). Together these are called “Special Inventory”.

The term “lead time” in this Section shall mean the lead time recorded on VEM’s MRP system at the time of procurement of Inventory and Special Inventory or at the time of the cancellation of the purchase order or termination of this Agreement whichever is greater.

VEM may purchase Long Lead-Time Components sufficient to meet all deliveries under the purchase orders and Product forecast in effect at the time the order with the supplier is placed, and may reasonably purchase Minimum Order Inventory even if greater than the amount necessary to meet purchase orders and Product forecast. Economic Order Inventory shall be purchased by VEM only with the prior approval of Customer.

In addition upon Customer’s written request, VEM may from time to time hold Long Lead-Time Components and finished Products in inventory to increase Customer’s sourcing flexibility. The components and quantities of all such inventory and the associated cost will be documented in a separate letter and signed by both VEM and Customer.

Customer will be responsible under the conditions provided elsewhere in this Agreement for all Inventory and Special Inventory purchased by VEM under this Section 2.3.

2.4 Preferred Supplier. Customer shall provide a list of vendors currently approved to provide the materials and components specified in the bill of materials for the Product (the “Approved Vendor List” or “AVL”). VEM shall purchase from vendors on a current AVL the materials and components required to manufacture the Product. Customer shall give VEM every opportunity to be included on AVL’s for materials and components that VEM can supply, and if VEM is competitive with other suppliers with respect to reasonable and unbiased criteria for acceptance established by Customer, VEM shall be included on such AVL’s. If VEM is on an AVL and its prices and quality are competitive with other vendors, Customer will raise no objection to VEM sourcing materials and components from itself. For purposes of this paragraph only, the term “VEM” includes any companies affiliated with VEM.
