Amendment No. 2 to the OUS Commercialization Agreement

Animas Corporation, a Delaware Corporation, having a principal place of business at 200 Lawrence Drive, West Chester, PA 19380 (“Animas” or “Distributor”) and DexCom, Inc., a Delaware corporation, having a principal place of business at 6340 Sequence Drive, San Diego, CA 92121 (“DexCom”), are parties to the OUS Commercialization Agreement dated January 12, 2009 (the “OUS Commercialization Agreement”), as amended on July 31, 2009 (“Amendment One”). Pursuant to Section 18.02 of the OUS Commercialization Agreement, the parties hereby wish to amend the OUS Commercialization Agreement as set forth below (“Amendment Two”). All terms not defined herein shall have the meaning set forth in the OUS Commercialization Agreement.

Article 1.        Agreement to Revised Transfer Pricing

1.1 Schedule B (Transfer Pricing) shall be deleted and replaced in its entirety with the revised Schedule B attached as Annex 1 hereto.

1.2 The second sentence of Section 3.05 of the OUS Commercialization Agreement is hereby amended to replace the phrase “On an annual basis” with “On an annual basis following the Initial Term, subject to Annex 1,”.

Article 2.        Complaint Handling, Technical Support and Clinical Training Activities

2.1.1 Distributor shall provide customer service support for the Integrated System in accordance with Section 7.01 of the OUS Commercialization Agreement (as amended hereby) and in accordance with Section 18 of the Quality Agreement. In the event of a conflict between the complaint handling process provided for in these two sections, Section 18 of the Quality Agreement shall govern. For clarity, the principal difference contemplated by this Amendment and the Quality Agreement compared with the original Section 7.01 of the OUS Commercialization Agreement is that Animas agrees to take on additional complaint handling, warranty handling and adverse event reporting responsibilities with respect to the Transmitter as the marketing authorization for the Transmitter upon launch shall be held by Animas.

2.1.2 With respect to any technical questions or issues relating to the Sensors, Transmitters and/or Embedded System, Distributor shall use the “Troubleshooting Guide” (referenced as Annex 2 hereto, and as may be supplemented from time to time by DexCom) to attempt to resolve such questions or issues. Any technical support questions or issues that are not resolved by Distributor’s application of the “Troubleshooting Guide” shall be

referred by email to DexCom by e-mailing DexCom’s technical support group, translated into English by Distributor if necessary.

2.2 Distributor shall receive the initial Sensor, Transmitter and Embedded System training contemplated by Section 5.02(a) of the OUS Commercialization Agreement in the United States, or at a location that will be mutually agreed upon, and the training must be completed prior to the first sale of the Integrated System. Should Distributor or its representatives request additional trainings in excess of what is provided for in Section 5.02(a) of the OUS Commercialization Agreement, such trainings shall be performed upon mutual consent and at Distributor’s expense.

Article 3.        Orders

3.1 Distributor shall order Sensors and Transmitters in minimum order quantities as set forth in Schedule B attached as Annex 1 hereto.

3.2 With respect to Transmitters, Distributor shall be responsible for ordering an initial safety stock, all subject to the pricing set forth in Annex 1.

Article 4.        Warranty; Replacement Transmitters and Sensors

4.1 Schedule C (Standard Warranties) of the OUS Commercialization Agreement shall be deleted and replaced in its entirety with the revised Schedule C referenced as Annex 3 hereto.

4.2 Section 7.01(d) of the OUS Commercialization Agreement is hereby amended to provide that, with respect to requests by Customers or end-users received by Distributor for replacement of the Transmitter under DexCom’s standard warranty, such warranty claims shall be handled by Distributor as follows:

4.2.1 Distributor shall provide the owner of the Transmitter with a returned goods authorization (“RGA”) from Distributor and return the Transmitter to Distributor in accordance with the terms of the RGA. Any costs associated with the RGA shall be borne by Distributor.

4.2.2 Distributor shall complete an examination of each returned Transmitter using test equipment and fixtures supplied by DexCom. Distributor agrees to maintain such test equipment and fixtures in good working condition. After examination, if Distributor determines that (i) the Transmitter failed to meet DexCom’s standard warranty and (ii) it has reason to believe that the Transmitter failed within [*****] of its receipt by the end-user seeking the warranty replacement, then a replacement Transmitter shall be shipped to the end-user by Distributor. Any shipment costs associated with the replacement shall be borne by Distributor.

4.2.3 On a [*****] basis, Distributor shall submit to DexCom an accounting of all warranty replacement transmitters issued by Distributor during the previous [*****]. Subject to Section 4.2.4, DexCom shall replace at no charge such quantity of Transmitters with the subsequent shipment of Transmitters and/or Sensors to Distributor. Distributor shall return to DexCom all Transmitters that Distributor has deemed to have

failed DexCom’s warranty.

4.2.4 Distributor must ship the Transmitters to Original Purchasers (as defined below) on or before the date indicated on the Transmitter packaging, which appears in the following format: SB – YYYY – MM – DD (the “Ship-By Date”). If Distributor fails to ship the Transmitter to an Original Purchaser by the Ship-By Date, then no replacement shall be required by DexCom. For purposes of this provision, an Original Purchaser shall include an end-user of the Transmitter, a sub-distributor of Distributor, a healthcare provider or a service provider facility.

4.3 A new Section 7.01(e) of the OUS Commercialization Agreement is hereby added to provide that, with respect to requests by Customers or end-users received by Distributor for replacement of the Sensors, such requests shall be handled by DexCom and Distributor as follows:

4.3.1 To the extent Distributor wishes to provide replacement Sensors to its end-users of the Integrated System in the ordinary course of business, then Distributor shall provide these using its inventory of Sensor 1-packs.

4.3.2 For purposes of administering the Replacement Rate, Distributor shall provide to DexCom, on a [*****] basis, a summary report of all Sensors replaced during the prior [*****], including Sensor Expiration Date and detail on end-user complaints and/or descriptions of Sensor failures.

4.3.3 For the first [*****] period following commercial launch, DexCom will provide to Distributor a supply of Sensors equivalent to [*****] of the quantity of Commercial Use Sensors ordered by Distributor free of charge (“Replacement Rate”). DexCom shall provide such supply in the form of Sensor 1-packs. The number of replacement Sensors will be determined based on each purchase order submitted to DexCom by Distributor, and such replacement Sensors will be included with each corresponding order. Sensor quantities will be rounded to the nearest whole Sensor.

4.3.3.4 The Replacement Rate shall be adjusted on a [*****] basis by DexCom on the basis of the actual rate of Gen4 Sensor replacements completed by Distributor as well as the actual rate of Gen4 Sensor replacements completed by DexCom on its stand-alone system. Any Sensors that are not used by an end-user prior to their Sensor Expiration Date shall not be included for purposes of determining the Replacement Rate.

4.4 The parties agree to revise the foregoing procedures, as appropriate, following transition of the Transmitter to a marketing authorization held by DexCom.

Article 5.        Other Undertakings

5.1 Copy and Claims Approval

5.1.1 Distributor and DexCom shall coordinate copy and claims approvals with respect to the Integrated System generally in accordance with Section 5.04(a), Section 5.05 and Section 6.01(b) of the OUS Commercialization Agreement, and anticipate agreeing to a standard
