THIS AGREEMENT REGARDING TERMS OF SALE ("Agreement") is entered into as of the 23rd day of May, 2003 ("Effective Date"), by and between AMI SEMICONDUCTOR, INC., on its own behalf and on behalf of its subsidiaries (individually and collectively, "AMIS"), a Delaware corporation having its principal place of business at ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, U.S.A., and DEXCOM, INC. ("DexCom"), a Delaware corporation, having its principal place of business at ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, U.S.A. AMIS and DexCom also are hereinafter referred to individually as a "party," and jointly as the "parties."

WHEREAS, DexCom desires to have AMIS design, manufacture and sell to DexCom certain semiconductor products, and AMIS desires to design, manufacture and sell to DexCom such semiconductor products; and,

WHEREAS, DexCom and AMIS desire to establish the terms and conditions of their business relationship, including the "Terms of Sale" that will govern all purchase orders submitted by DexCom and accepted by AMIS;

NOW, THEREFORE, for good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows:

ARTICLE I

All purchase orders issued by DexCom to AMIS shall be subject in each instance to acceptance in writing by AMIS, as evidenced exclusively by the issuance of a written acknowledgement of purchase order by AMIS.

* CERTAIN INFORMATION WITHIN THIS EXHIBIT HAS BEEN OMITTED AND THE NON-PUBLIC INFORMATION HAS BEEN FILED WITH THE SEC. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

such purchase orders, and the "DexCom/AMIS Terms of Sale" shall supersede in their entirety any preprinted terms and conditions contained in any purchase orders issued by DexCom to AMIS and/or in any acknowledgments of purchase orders issued by AMIS to DexCom (in the "DexCom/AMIS Terms of Sale" set forth below, the term "Seller" shall be deemed to refer to AMIS, and the term "Buyer" shall be deemed to refer to DexCom):

DEXCOM/AMIS TERMS OF SALE

1. ACCEPTANCE: THE TERMS OF SALE CONTAINED HEREIN APPLY TO ALL QUOTATIONS MADE AND PURCHASE ORDERS ENTERED INTO BY THE SELLER AND BUYER AS WELL AS TO THE DELIVERABLES DESCRIBED IN SELLER'S "FIRM PROPOSAL PREPARED FOR DEXCOM, BID CONTROL NUMBER (BCN) [*****] (A COPY OF WHICH IS ANNEXED TO THIS AGREEMENT AS EXHIBIT B), PERTAINING TO THE "SENSOR ASIC AND HANDHELD COMMUNICATOR" PROJECT. SOME OF THE TERMS SET OUT HERE MAY DIFFER FROM THOSE IN BUYER'S PURCHASE ORDER AND SOME MAY BE NEW. THESE TERMS OF SALE WILL CONTROL IN THE EVENT OF ANY ADDITIONAL OR INCONSISTENT TERMS IN BUYER'S PURCHASE ORDER. SELLER'S FAILURE TO OBJECT TO PROVISIONS CONTAINED IN ANY COMMUNICATION FROM BUYER SHALL NOT BE DEEMED A WAIVER OF THE PROVISIONS OF THESE TERMS OF SALE. ANY CHANGES IN THE TERMS CONTAINED HEREIN MUST SPECIFICALLY BE AGREED TO IN WRITING BY AN OFFICER OF THE SELLER BEFORE BECOMING BINDING ON EITHER THE SELLER OR THE BUYER. All orders or contracts must be consistent with these Terms of Sale, unless otherwise specifically agreed in writing by Seller. Seller agrees to accept and fulfill purchase orders submitted by Buyer to Seller that are consistent with these Terms of Sale, are consistent with mutually agreed-upon lead times, and encompass cumulative die quantities of up to [*****] units per year. Subject to the foregoing and to Seller's then-existing capacity constraints, Seller agrees to accept and fulfill additional purchase orders submitted by Buyer to Seller that are consistent with these Terms of Sale and are consistent with mutually agreed-upon quantities and lead times with respect to services and/or products encompassed by such purchase orders.

2. PAYMENT:

(a) Unless otherwise agreed, all invoices are due and payable thirty (30) days from the later of the date of invoice or product shipment and notification to Buyer. No discounts are authorized. Shipments, deliveries, and performance of work shall at all times be subject to the approval of the Seller's credit department or prepayment by Buyer. The Seller may at any time decline to make any shipments or deliveries or perform any work except upon receipt of payment or upon terms and conditions or security reasonably satisfactory to such department.

(b) If, in the judgment of the Seller, the financial condition of the Buyer at any time does not justify continuation of production or shipment on the terms of payment originally specified, for reasons including but not limited to Buyer's bankruptcy or insolvency, the Seller may require full or partial payment in advance and, in the event of the bankruptcy or insolvency of the Buyer or in the event any proceeding is brought by or against the Buyer under the bankruptcy or insolvency laws, the Seller shall be entitled to cancel any order then outstanding and shall receive reimbursement for its cancellation charges.

* CERTAIN INFORMATION WITHIN THIS EXHIBIT HAS BEEN OMITTED AND THE NON-PUBLIC INFORMATION HAS BEEN FILED WITH THE SEC. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

(c) Each shipment shall be considered a separate and independent transaction, and payment therefore shall be made accordingly shipments are delayed by the Buyer, payments shall become due on the date when the Seller is prepared to make shipment. If the work covered by the purchase order is delayed by the Buyer (e.g., Buyer does not perform its material undertakings in connection with the shipment), payments shall be made based on the purchase price and the percentage of completion. Products held for the Buyer as a result of delays by the Buyer shall be at the risk and expense of the Buyer.

3. TAXES: Unless otherwise provided herein, the amount of any present or future sales, revenue, excise or other taxes, fees, or other charges of any nature (but expressly excluding taxes on the income of Seller), imposed by any public authority, (national, state, local or other) applicable to the services or products covered by these Terms of Sale, or the performance of services and/or manufacture or sale of products hereunder, shall be added to the purchase price and shall be paid by the Buyer, or in lieu thereof, the Buyer shall provide the Seller with a tax exemption certificate acceptable to the taxing authority.

4. F.O.B. POINT: All sales are made F.O.B. point of shipment. Seller's title passes to Buyer, and Seller's liability as to delivery ceases, upon making delivery of material purchased hereunder to carrier at shipping point, the carrier acting as Buyer's agent. All claims for damages must be filed with the carrier. Shipments will normally be made by Parcel Post, United Parcel Service (UPS), Air Express, or Air Freight. Unless specific instructions from Buyer specify which of the foregoing methods of shipment is to be used, the Seller will exercise its own discretion.

5. DELIVERY:

(a) Shipping dates are approximate and are based upon prompt receipt from Buyer of all necessary information. In no event will Seller be liable for any re-procurement costs, nor for delay or non-delivery, due to causes beyond its reasonable control including, but not limited to, acts of God, acts of civil or military authority, priorities, fires, strikes, lockouts, slow-downs, shortages not within Seller's reasonable control, factory conditions not within Seller's reasonable control, labor conditions, yield problems not within Seller's reasonable control, and inability due to causes beyond the Seller's reasonable control to obtain necessary labor, materials, or manufacturing facilities. In the event of any such delay, the date of delivery shall, at the request of the Seller, be deferred for a period equal to the time lost by reason of the delay; provided that any delay (for any reason) in excess of three (3) months will entitle Buyer to cancel any (or all) pending orders.

(b) In the event Seller's production is curtailed for any of the above reasons so that Seller cannot deliver the full amount released hereunder, Seller may allocate production deliveries among its various customers then under contract for similar goods. The allocation will be made in a commercially fair and reasonable manner. When allocation has been made, Buyer will be notified of the estimated quota made available.

6. INTELLECTUAL PROPERTY:

* CERTAIN INFORMATION WITHIN THIS EXHIBIT HAS BEEN OMITTED AND THE NON-PUBLIC INFORMATION HAS BEEN FILED WITH THE SEC. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

(a) All intellectual property rights that belong to either party prior to and as of the date of the Agreement shall remain with such party. Except as otherwise expressly set forth herein, nothing contained in the Agreement shall operate or be construed to grant any license, by implication, estoppel or otherwise, under any of Buyer's or Seller's respective patents, copyrights, trade secrets, rights in mask work or other intellectual property rights.

(b) [*****]

(c) In the event that a product designed and/or manufactured by Seller for Buyer incorporates in its design any of Seller's proprietary standard cells, base arrays, macros and/or other design data, and Seller at any time thereafter determines that Seller cannot or will not manufacture such product (or if Seller is in material uncured breach of the Agreement or these Terms of Sale), then, provided that Buyer is not in material uncured breach of the Agreement or these Terms of Sale (or any other agreement between Seller and Buyer pertaining to the supply of integrated circuits), Seller agrees to grant and hereby grants to Buyer (subject to the following proviso) a perpetual, irrevocable, fully paid-up, royalty-free license to use the design specification, top-level schematics, top-level simulation results, cell simulation results and documentation pertaining to the uniquely-configured product design by Seller for Buyer (pursuant to Exhibit B annexed to the Agreement) solely for the purpose of having such uniquely configured product manufactured for Buyer by an alternative manufacturer (provided, however, that before Buyer uses or attempts to use the aforementioned design specification, top-level schematics, top-level simulation results, cell simulation results and/or documentation to have such uniquely-configured product manufactured for Buyer by an alternative manufacturer, Buyer must provide to Seller not less than ten (10) business days' written notice of such planned use by Buyer so as to permit Seller to seek such injunctive and/or other relief as Seller may deem appropriate in the event that Seller disputes Buyer's rights to such use).

(d) Buyer hereby represents and warrants to Seller that Buyer's provision to Seller of any Buyer design data, and Seller's use of such Buyer design data to design, develop and/or manufacture one or more integrated circuits for Buyer, does not: (i) constitute an unfair trade practice against any third party, (ii) misappropriate any trade secret of any third party, (iii) infringe any patent, copyright, mask work right, trademark or other intellectual property right of any third party, or (iv) tortiously interfere with or breach any contract between Buyer and any third party. Provided that Seller notifies Buyer promptly in writing and gives Buyer authority, information and assistance (at Buyer's expense) for the defense thereof. Buyer hereby agrees to defend, indemnify and hold harmless Seller against any claims, suits, actions, proceedings at law or in equity, inquiries and/or investigations brought or asserted by any third party(ies) ("Third Party Claims") against Seller, and any and all liability, damages, losses, costs and/or expenses, including reasonable attorney's fees and expenses, arising out of any such Third Party Claims (regardless of whether relating to unfair trade practice, misappropriation of a trade secret of any third party, infringement of any patent, copyright, mask work right, trademark or other intellectual property right of any third party, and/or tortious interference with or breach of any contract between Buyer and any third party) to the extent any such Third Party Claims arise from and/or are alleged to have arisen from: (i) Buyer's provision to Seller of Buyer's design data, (ii) Seller's use of Buyer's design data to design, develop and/or manufacture one or more integrated circuits for Buyer, and/or

* CERTAIN INFORMATION WITHIN THIS EXHIBIT HAS BEEN OMITTED AND THE NON-PUBLIC INFORMATION HAS BEEN FILED WITH THE SEC. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

(iii) compliance with Buyer's designs, specifications and/or instructions; provided, however, that Buyer shall have no indemnification obligations hereunder to the extent that a Third Party Claim arises from or is based on any combination by Seller of Buyer's design data, designs and/or specifications with other design data, designs or information not provided by Buyer. The sale of products by Seller does not convey any license, by implication, estoppel or otherwise, under patent claims covering combinations of those products with other devices or elements.

(e) Subject to subpart (d) above, and provided that Buyer notifies Seller promptly in writing and gives Seller authority, information and assistance (at Seller's expense) for the defense thereof, Seller hereby agrees to defend, indemnify and hold harmless Buyer against any Third Party Claims brought or asserted against Buyer, and any and all liability, damages, losses, costs and/or expenses, including reasonable attorneys' fees and expenses, arising out of any such Third Party Claims to the extent any such Third Party Claims arise from and/or are alleged to have arisen from: (i) a claim that any product, or any part thereof furnished by Seller hereunder constitutes an infringement of any U.S. patent, and/or (ii) any knowing and intentional misappropriation by Seller of proprietary information of any third parties. If such product, or any part thereof is held in such suit or proceeding to constitute infringement of a U.S. patent, and the use of such product is enjoined, Seller shall, at its own expense, procure for Buyer the right to continue using such product or part thereof, replace the same with a non-infringing product, modify, the product so that it becomes non-infringing, or authorize Buyer's return of such product to Seller and upon its receipt refund the price and transportation and installation costs thereof. Subject to subpart (f) below, the foregoing states the entire liability of Seller for infringement by such product or any part thereof. THIS PROVISION IS STATED IN LIEU OF ANY OTHER EXPRESS, IMPLIED OR STATUTORY WARRANTY AGAINST INFRINGEMENT, AND SHALL BE THE SOLE AND EXCLUSIVE REMEDY FOR INFRINGEMENT OF ANY KIND.

(f) In connection with any indemnification obligation under either subpart (d) or (e) above, the following additional provisions shall apply:

(i) the party seeking indemnification with respect to a Third Party Claim shall not enter into any settlement of such claim without the written consent of the indemnifying party (which consent shall not unreasonably be withheld, conditioned or delayed), and the indemnifying party shall not enter into any settlement of such Third Party Claim (unless such settlement is solely for payment of an amount no greater than the maximum amount for which the indemnifying party is obligated to provide indemnification hereunder and the indemnifying party agrees in writing to pay such amount and not to contest its indemnity obligation with respect thereto) without the written consent of the indemnified party (which consent shall not unreasonably be withheld, conditioned or delayed);

(ii) notwithstanding anything to the contrary in the Agreement or these Terms of Sale, under no circumstances shall an indemnified party be entitled to indemnification under this Paragraph 6 with respect to special, indirect or consequential damages suffered by the indemnified party itself and,

(iii) in no event shall Seller's or Buyer's total liability to the other party under or as a result of compliance with the provisions of subparts (d) and/or (e) above exceed the aggregate sum paid by Buyer to Seller for the NRE charges pertaining to the allegedly infringing product and for the purchase of production units of the allegedly infringing product.

7. INSPECTION: Unless otherwise specified and agreed upon, the material and/or products to be furnished under these Terms of Sale shall be subject to the Seller's standard inspection at the place of manufacture and to Buyer's standard inspection (provided that Buyer's standard inspection is based on standards that are no more restrictive than the parties' mutually agreed-upon specifications for the relevant products) at the place of manufacture or at Buyer's facilities following shipment (or both, as determined by Buyer). Any such inspection by Buyer at the place of manufacture shall be subject to prior written notice to Seller, shall be subject to Seller's confidentiality and security requirements, and shall be so conducted as to not interfere unreasonably with Seller's operations. Notwithstanding the foregoing, if, upon receipt of such material and/or products by Buyer, the same shall appear not to be free from defects in material and workmanship under normal use and service and to conform in all material respects to the then-current mutually agreed-upon product design specifications, the Buyer promptly shall notify, the Seller of such conditions and afford the Seller a reasonable opportunity to inspect the material and/or products. Seller's Return Material Authorization form, which Seller agrees to provide upon request from Buyer, must accompany such returned material and/or products.

8. LIMITED WARRANTY:

(a) The Seller warrants that the products to be delivered under these Terms of Sale will be free from defects in material and workmanship under normal use and service and will conform in all material respects to the then-current mutually agreed-upon product design specifications. Seller's obligations under this warranty are limited to replacing or repairing or giving credit for, at its option, at its factory, any of said products which shall, within one (1) year after shipment, be returned to the Seller's factory of origin, transportation charges prepaid, and which are, after examination, disclosed to the Seller's satisfaction to be thus defective. THIS WARRANTY IS EXPRESSED IN LIEU OF ALL OTHER WARRANTIES, EXPRESS, STATUTORY, OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, AND OF ALL OTHER OBLIGATIONS OR LIABILITIES ON THE SELLER'S PART, AND IT NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON TO ASSUME FOR THE SELLER ANY OTHER LIABILITIES IN CONNECTION WITH THE SALE OF THE SAID ARTICLES. This warranty shall not apply to any of such products which shall have been repaired or altered, except by the Seller, or which shall have been subjected to misuse, negligence, accident or improper storage. The aforementioned provisions do not extend the original warranty period of any product which has either been repaired or replaced by Seller.

(b) It is understood that if an order calls for the delivery of semiconductor devices which are not finished and fully encapsulated, then no warranty, statutory, express or implied, including the implied warranty of merchantability and fitness for a particular purpose, shall apply. All such devices are sold as is where is.

IN THE CASE OF PRODUCTS OTHER THAN INTEGRATED CIRCUITS OF SELLER'S OWN MANUFACTURE (OR, IF APPLICABLE, IN THE CASE OF INTEGRATED CIRCUITS MANUFACTURED BY A THIRD PARTY FOR SELLER WHICH THEN ARE SUPPLIED BY SELLER TO BUYER), SELLER MAKES NO WARRANTIES, EXPRESS, STATUTORY OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FREEDOM FROM PATENT INFRINGEMENT AND FITNESS FOR A PARTICULAR PURPOSE. Such products may be warranted by the original manufacturer of such products. For further information regarding the possible warranty of such products, contact Seller.

(c) The Buyer may make reasonable changes in the drawings, designs or specifications for the items, products and/or materials to be furnished hereunder without Seller's prior consent (provided that such changes do not result in a significant additional development

EXHIBIT A

INDEMNITY AGREEMENT

This Indemnity Agreement ("Agreement") is entered into as of May 23rd, 2003 ("Effective Date") by and between AMI SEMICONDUCTOR, INC. ("Seller"), a Delaware corporation, and DEXCOM, INC. ("Buyer"), a Delaware corporation.

Seller and Buyer hereby agree that Buyer shall protect, defend, save, hold harmless and indemnify Seller, its directors, officers, employees, agents, subsidiaries, successors and assigns (as well as each of Seller's suppliers and subcontractors, and their respective directors, officers, employees, agents, subsidiaries, successors and assigns, all of whom are expressly agreed to be intended third-party beneficiaries of this Agreement) against any and all claims, losses, damages, actions, suits, proceedings at law or in equity, government inquiries or investigations, and any and all liability, costs or expenses, including attorney's fees, arising out of or in connection with any claim or any threatened claim of property damage, economic loss or other damages, in each such case resulting from personal injury, including death, with regard to any product, any part of any product, or any direct or indirect use of any product or part of any product furnished to Buyer by Seller or Seller's agent, including without limitation the design, development, manufacture, assembly, selection, testing, delivery, possession and operation of any such product or part of such product. The obligations of this Agreement shall survive any cancellation, termination or expiration of any agreement, or any part thereof, including without limitation this Agreement, between Buyer and Seller.

Buyer will conduct and control, through counsel of its own choosing, any claim, action, suit, proceeding, government inquiry or investigation which is or may be subject to Buyer's defense, indemnity and other obligations set forth in the immediately preceding paragraph of this Agreement.

III. PROCEDURES & SCHEDULES

AMIS assures that all design needs will be satisfied in the [*****] process.

A. Design Procedure

The following is the list of design procedures:

•: DexCom and AMIS will do Phase 1 of the project where the specification is defined and finalized.
•: DexCom and AMIS will jointly agree on the design and test specification.
•: Test specification to be agreed upon before top-level design is complete.
•: AMIS will be responsible for the mixed signal design, layout, generation of fab tooling and test development and prototype production.
•: DexCom and AMIS will perform post layout review. Reticles can only be generated after review is complete.
•: AMIS will manufacture, assemble, test and deliver baseline samples and prototypes.

B. Implantable Meter Design Schedule

The preliminary design schedule is given in NRE Charges below. Handheld Design Schedule will be conducted in parallel.

Table 2: Implantable Meter Design Schedule

(1): These schedules will vary with the quality of the ASIC design data received and do not include any engineering queue time.

* CERTAIN INFORMATION WITHIN THIS EXHIBIT HAS BEEN OMITTED AND THE NON-PUBLIC INFORMATION HAS BEEN FILED WITH THE SEC. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

(2): Specification definition and specification formalization phase must be completed and a firm specification in place by customer before AMIS begins design work.
(3): The schedule only represents AMIS' part of the development and does not include any delays due to customer.
(4): Tape out is defined as completion and approvals of post-layout simulations. It is also assumed that all necessary DRC and LVS checking is completed.
(5): Wafer fabrication assumes a priority expedite in fab. Although AMIS makes every effort to secure these expedite for first silicon lots, AMIS does not guarantee that an expedite will be available when the device starts fab—which could affect the schedule. If a priority expedite is not readily available the device will start in fab. Once in fab, the device may be placed on an expedite, should one become available.
