DEVELOPMENT AGREEMENT

Exhibit 10.1

DEVELOPMENT AGREEMENT

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

This Development Agreement (this “Agreement”) is made and entered into on June 4, 2015 (the “Effective Date”) by and between Tandem Diabetes Care, Inc., a Delaware corporation, having a principal place of business at 00000 Xxxxxxx Xx., Xxx Xxxxx, XX 00000 (“Tandem”) and DexCom, Inc., a Delaware corporation, having a principal place of business at 0000 Xxxxxxxx Xxxxx, Xxx Xxxxx, XX 00000 (“DexCom”).

Background

A. DexCom is in the business of developing and commercializing continuous glucose monitoring systems, and is currently developing the DexCom G5 System (as defined below).  

B. Tandem has developed, and is developing, current and next generations of insulin infusion pump systems.

C. The parties believe it is in each of their best interests to enable Tandem to adapt the Tandem Display Device (defined below) to identify, receive, and display information from the DexCom G5 System, which is adapted to communicate information on a one-way basis between a DexCom Sensor (defined below) via the DexCom BT CGM Transmitter (defined below) to an external receiver or other display, such as the Tandem Display Device.

The parties therefore agree as follows:

1. Definitions  

1.1. “Affiliates” means any corporation or other entity that is directly or indirectly controlling, controlled by or under common control with a party.  For the purpose of this definition, “control” means the direct or indirect ownership of more than fifty percent (50%) of the capital stock of the subject entity entitled to vote in the election of directors (or, in the case of an entity that is not a corporation, interests entitled to vote in the election of the corresponding managing authority).

1.2. “Communication Protocol” will have the meaning given to that term in Section 2.2 below.

1.3. “DexCom BT CGM Transmitter” means the transmitter component of the DexCom G5 System that is configured to transmit information from a DexCom Sensor via

Bluetooth to any receiver adapted to identify, receive, and display such information, and is also controlled from an authenticated receiver, such as the DexCom Receiver, and the DexCom CGM Smartphone App.

1.4. “DexCom CGM-Enabled Tandem Display Device” means a Tandem Display Device comprising a receiver or other component of the Tandem Insulin Infusion Pump configured to identify, receive, interpret, process and/or display DexCom Sensor Information from a DexCom BT CGM Transmitter and control the DexCom BT CGM Transmitter.  A DexCom CGM-Enabled Tandem Display Device will be independently developed by Tandem pursuant to Section 2.1 and is not, and will not be, a component of a DexCom G5 System.

1.5. DexCom CGM Smartphone App” means the smartphone application component of the DexCom G5 System that identifies, receives, deciphers and displays information transmitted by a DexCom BT CGM Transmitter from a DexCom Sensor, and also enables control of the DexCom BT CGM Transmitter by receiving and transmitting data to the DexCom G5 System, such as configuration settings and calibration values.

1.6. “DexCom G5 System” means DexCom’s fifth generation continuous glucose monitoring system comprised of the following components, all designed, developed and manufactured by DexCom: a DexCom Sensor, a DexCom BT CGM Transmitter, DexCom Sensor Information, the Communication Protocol, a DexCom Receiver, and the DexCom CGM Smartphone App.

1.7. “DexCom Receiver” means a component of the DexCom G5 System that identifies, receives, deciphers and displays information transmitted by a DexCom BT CGM Transmitter from a DexCom Sensor, and also enables control of the DexCom Transmitter by receiving and transmitting data to the DexCom G5 System, such as configuration settings and calibration values.

1.8. “DexCom Sensor” means the component of the DexCom G5 System comprising a continuous glucose monitoring electrode sensor, adapted to (i) penetrate the patient’s skin to come into contact with the patient’s interstitial fluid, (ii) measure interstitial fluid glucose level, and (iii) be operably coupled to a DexCom BT CGM Transmitter to communicate the blood glucose value as measured by the DexCom Sensor to a separate receiver.

1.9. “DexCom Sensor Information” consists of a DexCom BT CGM Transmitter interface spec that specifies contents of the transmitter broadcast message and the available control functions (the “Specification”).  The transmitter broadcast message will contains items such as estimated glucose value, device display time stamp information, the trend arrow and calibration confidence intervals as stored in the DexCom BT CGM Transmitter.  The control functions provide the commands required to start session, stop session and calibrate.  Any additional sensor information to be shared must be

2.

agreed in writing by both parties or shall be the result of DexCom’s updating of the Specification, which shall be permitted without requiring compliance with Section 10.7. The term “DexCom Sensor Information” shall in no way be construed to include the Raw Data.

1.10. “Effective Date” is the date set forth in the preamble above.

1.11. "Integrated System" shall mean a Tandem System that implements the Communication Protocol and is capable, among other things, of receiving and displaying continuous glucose monitoring data generated by the DexCom G5 System.

1.12. "Intellectual Property Rights" means (collectively): copyright rights (including, without limitation, the exclusive right to use, reproduce, modify, distribute, publicly display and publicly perform the copyrighted work), trademark rights (including, without limitation trade names, trademarks, service marks, and trade dress), patent rights (including, without limitation, the exclusive right to make, have made, import, use, sell and offer to sell), trade secrets, rights of publicity, authors’ and moral rights, goodwill and all other intellectual and industrial property rights as may exist now and/or hereafter come into existence and all renewals, reissues and extensions thereof, regardless of whether such rights arise under the laws of the United States or any other U.S. state or other country or jurisdiction.

1.13. “Raw Data” means any raw data used by the DexCom G5 System or any other data generated or stored by the DexCom G5 System that is not included in the definition of DexCom Sensor Information.

1.14. “Tandem Display Device” means a device used in connection with, or component of the, Tandem Insulin Infusion Pump that communicates with and controls the Tandem Insulin Infusion Pump and which also stores and processes data related to the Tandem System.

1.15. “Tandem Insulin Infusion Pump” means a subcutaneous infusion pump for insulin delivery, either alone or together with other medicaments.

1.16. “Tandem System” means a subcutaneous infusion system comprised of the following components: a Tandem Insulin Infusion Pump and a Tandem Display Device.
