PURCHASE AGREEMENT

1.     GENERAL

1.1.

Parties. This Purchase Agreement ("AGREEMENT") is entered into this fourteenth day of September, 2001 ("Effective Date") by Varian, Inc., a Delaware corporation, Electronics Manufacturing, 615 South River Drive, Tempe, Arizona 85281 ("VEM"), and Cardionet, Incorporated, a California corporation, whose principal place of business is 510 Market Street, San Diego, California 92101 ("CARDIONET").



1.2.

Purpose and Agreement. The purpose of this AGREEMENT is to establish the terms and conditions under which VEM agrees to assemble for CARDIONET a line of products identified on Schedule A of APPENDIX A (herein "Product(s) or "Unit(s)"). VEM agrees to assemble for CARDIONET and CARDIONET agrees to purchase from VEM the Products according to the drawings, specifications and bills of material supplied by CARDIONET and accepted by VEM. CARDIONET desires to purchase such Products from VEM in accordance with the mutual covenants, agreements, representations and other terms and conditions of this AGREEMENT ("Terms and Conditions").



1.3.

Applicability. All VEM Products and services are furnished only on the Terms and Conditions stated herein to the exclusion of any CARDIONET terms and conditions in any specific order documentation, or on the face of any VEM Quotation, preprinted or otherwise, except as to identification and quantity of Products. Both parties agree that the Terms and Conditions herein will govern with respect to all sales and orders hereunder, unless in a particular case they mutually agree to the contrary. This AGREEMENT shall be part of each Quotation issued by VEM to CARDIONET and each Purchase Order issued by CARDIONET to VEM, whether or not referenced on such Quotation or Purchase Order, and this AGREEMENT shall apply automatically to any purchase or sale transaction between CARDIONET and VEM whether or not such legend appears on the relevant documents.



1.4.

Effective Date. This AGREEMENT shall commence on the Effective Date.



1.5.

Definitions. As used herein: See Schedule A

2.     PRICES

2.1

Per Unit Prices. On or around the date hereof, VEM will provide CARDIONET a quotation for the price per unit for the Products. The price quoted shall be firm for all purchase orders issued to VEM by CARDIONET within 45 days of the date of the quotation (the "Expiration Date"). VEM reviews the prices of the labor, parts, and material no less often than monthly and reserves the right to re-quote the price per Unit for all purchase orders issued after the expiration date of the prior quotation (the "Revised Quotation"). At least one week prior to the Expiration Date of each quotation, VEM agrees to provide to CARDIONET either confirmation that the expiring quotation is firm for the next 45-day period or to issue a Revised Quotation. VEM will only notify CARDIONET of price changes, if pricing does not change no notification will be sent to CARDIONET.

VEM agrees that each Revised Quotation shall provide sufficient detail to allow CARDIONET to understand the changes in labor, parts and material over the prior quotation.

In addition, the parties agree to meet no less often than quarterly, as long as this agreement is in effect, to review in detail the product specifications, bill of materials, approved supplier list, prices for the Products, delivery, quality and other business issues as necessary.

2

The original and each successive quotation will be incorporated in this agreement as Schedule B.

2.2

Per Unit Price Changes. In the event of unanticipated cost changes of [. . . *** . . .] of the original total cost, for reasons outside VEM's control, VEM may change firm or agreed prices on future purchase orders so long as the price change is not due to negligence on the part of VEM as follows: VEM will present the cost change information to CARDIONET for review and consideration. Any changes to previously agreed pricing will be negotiated with CARDIONET. It will be the responsibility of VEM to show just cause for any price change, and it will be the responsibility of CARDIONET to show just cause for refusal of VEM submitted price change. If VEM and CARDIONET are not able to reach agreement on new pricing, VEM will perform according to the original purchase orders and original prices on existing purchase Orders and a plan will be developed by VEM and CARDIONET for an orderly transition, terminating this agreement.



2.3

In addition, VEM may change prices if CARDIONET requests changes to the drawings, specifications or bills of material, thereby resulting in an Engineering Change Order (ECO). CARDIONET authentication of VEM generated ECO implementation documentation will constitute CARDIONET acceptance of new pricing. CARDIONET will issue Change Orders to affected Purchase Orders for new agreed upon pricing.



2.4

NRE Charges. In addition to Per Unit Prices, VEM will charge and CARDIONET will pay for the previously quoted costs of reimbursable non-recurring engineering (NRE) charges related to assembly of Units for CARDIONET. Issuance of Purchase Orders by CARDIONET for such Products will confirm acceptance of NRE Charges.



2.5

VEM Cost Information. VEM will provide cost breakdown information with its Quotations for Products; provided, however, it shall be used only as CARDIONET's internal company information. Any such information supplied by VEM shall be considered the "Confidential Information" of VEM subject to the obligations not to use or disclose the same as provided in the nondisclosure agreement between the parties.



2.6

Taxes. All taxes or charges, other than those based upon net income, imposed by any taxing authority upon the manufacture, sale, shipment, or use of the Units which VEM is obligated to pay or collect, including customs and duties, shall be the responsibility of CARDIONET and if not paid directly by CARDIONET shall be added to the purchase price paid by CARDIONET to VEM unless CARDIONET provides VEM with tax exemption certificates acceptable to the appropriate taxing authorities. CARDIONET will notify VEM in writing via Purchase Order or advise VEM of any Units that are not intended for resale; so that applicable sales and/or use taxes may be applied. If CARDIONET does not provide such notice, CARDIONET will accrue and pay appropriate authorities directly.

3      DELIVERY

3.1.

Forecasts. The forecasting, scheduling and delivery of Products will be handled in the following manner in order to enhance the ability of CARDIONET and VEM to optimize asset flow. In order to provide this flexibility in VEM's normal mode of operation, commitment to material flow in the VEM "pipeline" will be governed by the lead time of the materials, and based on purchase order requirements for materials whose lead times fall within the purchase order window and by forecasts for those materials whose lead times fall outside the purchase order window. VEM will provide in writing, a list of all materials falling outside the purchase order lead time window prior to VEM's procurement of those materials. The actual implementation of Purchase Order activity may change from time to time as the
