Exhibit C

Monitor Provisioning, Activation and Operating Procedures

        Provisioning Process.    CardioNet shall ensure that the manufacturer of the modules that will be used in each Monitor sends to the Wireless Carrier an equipment data file ("EDF" or "flat file") identifying the ESN for such modules, and QUALCOMM shall have no responsibility regarding the sending of such EDF or flat file to the Wireless Carrier. CardioNet shall provide to QUALCOMM (or ensure that such module manufacturer provides to QUALCOMM) such EDF or flat file. After the Wireless Carrier has received such EDF or flat file from the module manufacturer, the provisioning process is complete. Once the Wireless Carrier has completed the provisioning process for each Monitor, CardioNet may choose to activate such Monitors by using the activation process set forth below.

        Activation Process.    CardioNet shall utilize the QUALCOMM iQConnect website to initiate, monitor and retrieve activation information. The Wireless Carrier will assign a MDN to each ESN and will notify QUALCOMM at such time as the Wireless Carrier has completed such MDN assignments. The Monitors shall be considered activated for data service and Voice Service upon receipt by CardioNet of such MDN assignment notification from QUALCOMM via the IQConnect website (the "Activation Date"). Billing to CardioNet for such activated Monitors for Voice Service and data service will commence upon the Activation Date. The applicable fees for Monitor activation are set forth in Exhibit B. QUALCOMM shall use commercially reasonable efforts to complete any activation and/or other maintenance requests submitted by CardioNet within two (2) Business Days of their submission to QUALCOMM. CardioNet shall use commercially reasonable efforts to batch Monitors for which CardioNet is requesting activation into groups of not less than ten (10) Monitors at any one time.

        Monitor De-Activation.    CardioNet may de-activate Monitors via the IQConnect website. QUALCOMM shall promptly forward such de-activation request to the Wireless Carrier, and QUALCOMM shall use commercially reasonable efforts to ensure that the Monitors for which de-activation has been requested are de-activated within thirty (30) days of CardioNet's request. CardioNet shall pay to QUALCOMM the Service Plan Fees for voice and data services for the Monitors, as set forth in Exhibit B, until such time as the Wireless Carrier has actually de-activated such Monitors. The applicable fees for Monitor de-activation are set forth in Exhibit B.

22

Exhibit D

Customer Service and Support Requirements

        QUALCOMM Customer Service and Support Requirements.    QUALCOMM shall provide to CardioNet 7/24/365 technical support through iQConnect and/or QUALCOMM's Customer Service Center Hotline at (800) 541-7490, or such as other number as may be designated by QUALCOMM. For calls placed to QUALCOMM's Customer Service Center Hotline, QUALCOMM shall provide an initial response to any problem or inquiry reported by CardioNet and which QUALCOMM has determined, in its reasonable discretion, is reasonably related to the QUALCOMM Service, within thirty (30) minutes of CardioNet's inquiry. Such initial response shall serve as an acknowledgment to CardioNet that QUALCOMM has received the inquiry, and shall include QUALCOMM's estimate as to when CardioNet can expect additional information or resolution of the problem. In the event the reported problem is within QUALCOMM's control, QUALCOMM shall use commercially reasonable efforts to promptly identify and resolve the problem. In the event the reported problem is identified by QUALCOMM as being related to the Wireless Carrier or its facilities or network or is otherwise out of the control of QUALCOMM, QUALCOMM shall work with the Wireless Carrier to monitor, escalate, and coordinate the resolution of the problem, and QUALCOMM shall provide periodic updates to CardioNet as to the status of the problem resolution efforts.

        Problem Escalation Process.    CardioNet shall be solely responsible for providing any customer service and support regarding the CardioNet Service directly to the Monitored Person and Prescribing Entities, and QUALCOMM shall have no obligation to any Monitored Person, Prescribing Entity or any third party for any such customer service and support. No calls shall initiate from a Monitored Person, Prescribing Entity or other third party directly to QUALCOMM, and CardioNet shall instruct all Monitored Persons and Prescribing Entities to contact CardioNet directly for all administrative and technical services. If after providing support to the best of its abilities CardioNet determines it is unable to resolve an issue related to the QUALCOMM Service, CardioNet may call QUALCOMM's Customer Service Center Hotline for assistance on supporting the QUALCOMM Service or send email to qc-support@qualcomm.com. CardioNet shall provide to QUALCOMM the following information when contacting QUALCOMM for technical support: (i) the nature of the problem; (ii) document specific symptoms of the problem; (iii) timeline of the symptoms (when did the problem occur, what is affected); (iv) if necessary and applicable, specific Monitor information, module ESN and/or MDN information.

        Notification for Scheduled Maintenance.    QUALCOMM shall provide to CardioNet a minimum of twenty four (24) hours advance notice of any scheduled downtime planned by QUALCOMM. QUALCOMM scheduled down times for the QUALCOMM Service will only occur within a specific maintenance window of 10 p.m. to 12 a.m. Pacific Time, as set forth in Section 4.1. QUALCOMM shall use commercially reasonable efforts to limit scheduled downtime to a cumulative one (1) hour per calendar week. QUALCOMM shall use commercially reasonable efforts to coordinate maintenance activities with any required CardioNet maintenance activities. QUALCOMM shall use commercially reasonable efforts to pass through to CardioNet within twenty-four (24) hours of receipt by QUALCOMM any downtime notifications that QUALCOMM receives from the Wireless Carrier.

        Notification for Unscheduled Maintenance.    CardioNet acknowledges and agrees that, from time to time, QUALCOMM may need to perform maintenance and/or other activities regarding the QUALCOMM Service and the NMF in a manner that requires unscheduled downtime. In the event of any unscheduled downtime for the QUALCOMM Service and/or the NMF, QUALCOMM shall use commercially reasonable efforts to provide to CardioNet initial notification of such unscheduled downtime to a designated CardioNet phone number and/or pager within fifteen (15) minutes of such downtime event. In the event that the CardioNet contact does not respond within fifteen (15) minutes of QUALCOMM's initial notification, QUALCOMM shall activate further escalation to a

23

CardioNet-supplied list of phone numbers. QUALCOMM's initial notification shall include the scope of the downtime activity and the possible impact to the CardioNet Service (to the extent they are each understood at the time), and an estimated time of resolution. In the event the downtime activity is not completed within thirty (30) minutes, QUALCOMM shall provide to CardioNet regular and periodic updates until completion of the downtime activity.
