 3. SUPPLY: During the term of this Agreement, AFC will manufacture Product for GSL for use in
manufacture of Finished Product (as defined in Section 4 below). During the term of this Agreement, AFC is obligated to manufacture Product at the location and in the quantities set forth herein. AFC will not manufacture or supply Product to
any person or entity other than GSL without GSL’s prior written consent. 
  

	 	a)	Facility: AFC will manufacture the Product for GSL only at its facility located at Rancho Cordova, CA, or such other facilities as the Parties agree to in
writing (collectively, the “Facility”). GSL has inspected the Facility and has acknowledged, based upon information in its possession as of the Effective Date, that the Facility appears to be appropriate for the purposes of
manufacturing the Products. 

  

	 	b)	Minimum Quantities: During the Initial Term and any renewal term GSL will purchase and AFC will deliver at least the quantities of Product set forth in Exhibit
A. Failure in any year by GSL to purchase the required quantities will result in [*] an amount equal to the [*], the invoice for which will be [*], and such invoice shall be [*]. For clarity, GSL’s
failure to satisfy minimum purchase requirements due to Regulatory Terminations (as defined in Section 13(c) below) shall not be deemed to be breaches by GSL of GSL’s obligations under this Section 3(b). 


 

	 	c)	Forecasting: Prior to [*] of [*], GSL shall provide to AFC a [*] for the [*]. Such GSL Purchase Order shall detail the [*],
and shall be [*]. 

  

	 	d)	Acceptance: AFC will respond in writing to each purchase order received from GSL (“GSL Purchase Order”) within [*] calendar days of
receipt. The response shall include AFC’s inability to comply with, or confirmation of the delivery dates and quantities set forth in the GSL Purchase Order. 


 

	 	e)	Failure to Supply: If AFC is unable to supply sufficient quantities of the Product to meet its minimum obligations under Section 3(b), or should either
Party perceive that a shortfall (according to the definition of shortfall in Section 3(f)) in delivery of Product by AFC is likely to occur for any reason, the Parties will [*]. GSL will have the right [*] or [*].
Any quantities [*] to meet such a shortfall shall be [*]. If GSL must [*], AFC shall be liable for [*]. Repeated shortfalls may be considered a material breach of this Agreement, as described in Section 13 of this
Agreement. 

  

	 	f)	Delay: If release and/or shipment of any quantity is delayed after AFC has accepted an order, through the fault of AFC, by more than [*] days
[*], the quantity shall be considered a shortfall, and treated as above in Section 3(e). If such delay is caused by the fault of GSL, GSL will make [*] to remediate the fault [*], however, after ([*]) days
from the date of expected release and/or shipment, AFC shall be entitled to issue the relevant invoice(s) in any case. 

  

	 	g)	 Successful Close-out: GSL acknowledges that AFC received a Warning Letter from




  
 [*] = CERTAIN
CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, IS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED 









	 	 
the FDA on June 25, 2010 in association with a Form FDA 483 received in February 2010 (the “Warning Letter”). AFC agrees to use its reasonable best efforts to
remediate the deficiencies identified by the FDA in a timely manner. AFC will either (i) provide Gilead with a copy of the close-out letter received from the FDA following the FDA’s re-inspection indicating the FDA’s satisfaction with
the corrective actions taken by AFC in response to the Warning Letter, or (ii) following such re-inspection by the FDA provide Gilead with a written certification signed by a senior officer of AFC that it has satisfied the concerns raised by
the FDA pursuant to the Warning Letter. Once Gilead has received either a copy of such close-out letter or such written certification, Gilead will acknowledge such event as a “Successful Close-out”. If a Successful
Close-out is not achieved by AFC following the FDA’s re-inspection, GSL will have the option to issue a Regulatory Termination in accordance with Section 13(c) below with the exception that the thirty (30) day notice period
shall not apply, and at GSL’s discretion this may be considered an Adverse Event per Section 17. 


 4. GOOD
MANUFACTURING PRACTICES: AFC expressly warrants that all Product covered by these terms have been manufactured in accordance with current good manufacturing practices (“cGMP”) as established by the United States Food and Drug
Administration (the “FDA”) for the manufacture of pharmaceutical materials, as well as other applicable rules and regulations of the FDA and other governmental or regulatory agencies of United States or other countries where
finished pharmaceutical products of GSL incorporating the Product (collectively, the “Finished Products”) are marketed with jurisdiction over the manufacture, use, or sale of Product, as then in effect. Each
party shall promptly notify the other of any new instructions or specifications required by the FDA, the Federal Food, Drug and Cosmetic Act, the Federal Public Health Service Act or other applicable regulations of the United States and/or other
countries where the Finished Products are marketed, and shall confer with each other with respect to the best means to comply with such requirements and shall allocate any costs of implementing such changes on an equitable basis. Upon written
request of GSL, AFC will permit representatives of GSL to observe such manufacture, or any government inspection of AFC’s manufacturing process for the Products covered by these terms, at mutually agreeable times and AFC shall permit GSL to
inspect copies of AFC’s manufacturing records, including its batch records, for the purposes of assuring product quality and compliance with agreed-upon manufacturing procedures. 
 5. MANUFACTURING PROCESS: GSL shall make available to AFC, [*], all such know-how, information, and technical assistance if needed by AFC so as to allow AFC to manufacture Product
with utmost efficiency and to the standard of GSL as will be more precisely described by GSL in writing to AFC before the start of manufacturing of the Product. AFC shall manufacture the Product in conformance with the relevant specifications, as
then in effect (the “Specifications”) and according to the manufacturing process description as set forth in the Gilead Sciences Tenofovir DF Contract Manufacturing Manual dated June 6, 2000, and as thereafter amended (the
“Contract Manufacturing Manual”).

 6. RAW MATERIALS: Raw materials used in the manufacture of Product will conform to the specifications
set forth in the Contract Manufacturing Manual (the “Raw Material Specifications”) and such conformance will be verified in accordance with the testing standards and procedures specified therein. AFC agrees that it will facilitate
changes to the Raw Material Specifications that are necessary or appropriate in light of FDA or other regulatory requirements. AFC shall not be liable hereunder if the raw materials meet the Raw Material Specifications and the Product fails to meet
the Specifications because the Raw Material Specifications are inadequate. 
 7. CHANGE IN MANUFACTURING PROCESS: AFC shall obtain
GSL’s prior written approval, per the Quality Agreement (August 1, 2010), before implementing any planned change in the materials, equipment, process, or procedures used to manufacture the Product that would constitute a major change under
cGMP, or that would constitute noncompliance with the manufacturing process set forth in the Contract Manufacturing Manual. AFC shall disclose all proposed changes in such manufacturing materials, equipment, process, or procedure to GSL at a level
sufficient to allow GSL to practice such changed manufacturing process. GSL shall notify AFC of any change in the materials, equipment, process, analytical methods, specifications, or procedures to be used in the manufacture of the Product in
writing, by means of timely updates to the Contract Manufacturing Manual, identical copies of which reside at AFC and GSL. AFC shall provide GSL with an authentic copy of the current master batch record for the preparation of the Product. The cost
of implementing any amendment or change of whatever nature to the procedures described in the Contract Manufacturing Manual, as well as any extra costs resulting from the implementation of such change, shall be borne by [*]. However, the
Parties recognize the pricing agreed in Exhibit A reflect implementation of the process developed by AFC and GSL during 2009-2010, which, at the time of this agreement, is not represented in the Contract Manufacturing Manual. 

8. PROCESS IMPROVEMENTS: 
  

	 	a)	[*] agrees to communicate to [*] any idea and substantial improvement made by [*] arising from [*] under the following conditions:
(i) all rights and title to improvements (patented or unpatentable) which are related to the [*] shall be assigned to [*], which shall have only the right to utilize such improvements in the manufacture of the Product;
(ii) all rights and title to improvements (patented or unpatentable) which apply to the [*], and provided that [*], is not contained in said improvements, shall be assigned to [*], which shall have only the right to utilize
such improvements in the process of the Product; (iii) a royalty-free worldwide exclusive license [*] shall be granted by [*] to [*] for improvements (patented or unpatentable) related to said processing [*];
(iv) in the event that [*] contracts out the manufacture of the Product to any third party, any improvement made by [*] hereunder may be disclosed to such contract manufacturer but rights to use the same shall be restricted to the
manufacture of the Product and the Parties hereto will [*]. 

  

	 	b)	 The Parties recognize the process changes under development by AFC and GSL for piloting and validation in 2010. All rights to said improvement shall be
passed to [*], in 



  
 [*] = CERTAIN

accordance with the provisions of Section 8(a), (i) through (iii), above. The Parties confirm no further remuneration shall be sought by [*] under Section 8(a)(iv)
above. AFC will produce a development report describing such revised process to be provided to GSL prior to commercial scale validation of such process. Further, AFC shall provide to GSL necessary assistance in support of technology transfer to one
Gilead Sciences, Inc.-owned facility, which may include teleconferences, meetings, and chemistry support during the initial commercial campaign. 


 9. QUALITY CONTROL SAMPLE AND DOCUMENTATION: Manufacture of the Product shall at all times be in strict conformance with the Specifications and such conformance will be verified in accordance with
the testing procedures, specified herein. Prior to the delivery of any batch of Product, AFC shall provide GSL with (i) a quality control sample of such batch to be held by GSL for analytical reference, (ii) written confirmation that the
batch records for such batch have been reviewed and approved by AFC’s quality assurance unit (Certificate of Compliance), and (iii) a Certificate of Analysis confirming that such batch meets Specifications. No delivery of the Product shall
be made until GSL accepts the material in accordance with the provisions of Paragraph 10. 
 10. BATCH ACCEPTANCE AND REJECTION: GSL
shall have the right without penalty to cancel delivery of an entire batch of Product at any time within [*] days after receipt of the applicable Certificate of Compliance and Certificate of Analysis (the “Acceptance Period”). Title
and risk of loss for each batch of Product shall pass to GSL upon [*]. If no such notice of rejection is received, GSL shall be deemed to have accepted the batch of Product upon the expiration of Acceptance Period. Either GSL’s written
acceptance of the batch or expiration of the Acceptance Period shall result in GSL assuming title and risk of loss for related batch. AFC shall be authorized to make delivery of the full batch upon GSL’s acceptance of the batch, pending receipt
of specific delivery instructions from GSL. AFC represents and warrants that the Product delivered to the destination specified by GSL shall comply with the Specifications for the Product. Any contestation of the quantity of Product delivered to the
destination specified by GSL or the related documentation must be made in writing to AFC within [*] days from receipt thereof by GSL or an agent of GSL. GSL and AFC shall [*] or [*], as appropriate. After notice of rejection is
given, GSL shall cooperate with AFC in determining whether rejection is necessary or justified. AFC will evaluate process issues and other reasons for such non-compliance. AFC shall notify GSL as promptly as reasonably possible whether it accepts
GSL’s basis for any rejection. In the event that such contestation of quality by GSL is not accepted by AFC, a sample of the contested batch sealed by AFC in compliance with applicable regulations shall be submitted by AFC to an independent
laboratory, acceptable to GSL, and the check assay of said laboratory shall be accepted by the two Parties as final and binding. The cost of said analysis made by the laboratory shall be borne by the failing party. Whether or not AFC accepts
GSL’s basis for rejection, AFC shall use reasonable efforts at GSL’s request to replace such rejected Product. If the third party laboratory determines that the batch meets the Specifications, GSL guarantees to purchase that batch at the
agreed-upon price, irrespective of whether AFC has already replaced it. GSL may not destroy any batch of Product until it receives 

  
 [*] = CERTAIN
CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, IS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED 








 
written notification from AFC that AFC does not dispute that the batch fails to meet Specifications and that AFC does not request return of the Product. Upon authorization from AFC to do so, GSL
shall destroy the Product received in the rejected delivery promptly at AFC’s cost and provide AFC with certification of such destruction. GSL shall, upon receipt of AFC’s request for return, promptly return said Product or quality control
sample to AFC, at AFC’s cost. At its election, GSL may treat any rejected batch of Product as [*], until and unless it is finally determined that the batch complied with the warranties in Section 14. 

11. QUANTITY AND PRICE: The quantity, schedule, and purchase price of Product covered by these terms will be provided in separate GSL Purchase
Orders. These terms shall apply to all GSL Purchase Orders written while these terms are in effect. All GSL Purchase Orders covered by this agreement shall reference this agreement by its effective date. The negotiated price for the Product shall
include up to [*] storage at AFC’s facility, according to Paragraph 25. 
 12. DELIVERY, SHIPPING, BILLING AND PAYMENT: GSL
will provide AFC with an estimated delivery date for each batch at the end of the Acceptance Period or at the time of acceptance of the batch, if earlier. GSL will then have [*] days to schedule processing of the Product with its contracted
formulation and encapsulation facility and provide specific delivery instructions to AFC. If specific delivery instructions are not provided to AFC within the [*] day period, the “Warehousing” provision included under Paragraph 25
will be considered in effect and GSL will have [*] days to provide the written request and other information required to be provided to AFC under that provision. AFC will package and load the Product in accordance with AFC’s customary
practices for pharmaceutical compounds, unless otherwise specified by GSL. Unless otherwise agreed to by the Parties in writing, all shipments shall be shipped [*] pursuant to written instructions provided by GSL to AFC. The quantity of
Product made available to GSL’s carrier shall be the same amount as invoiced by AFC, unless AFC is otherwise directed in writing by GSL. AFC shall maintain appropriate insurance as far as AFC’s custodial responsibilities with respect to
the Product temporarily held at AFC’s facility and owned by GSL. [*] is responsible for selecting the carrier that will transport the Product. GSL will maintain the appropriate insurance coverage for Product that it has accepted,
including any Product owned by GSL held temporarily or stored at AFC’s facility. Within [*] calendar days of receipt of such shipping instructions from GSL, AFC shall ship the invoiced amount of Product to its destination. All invoices
from AFC to GSL covering Product shipped to GSL shall be stated, and all payments to AFC by GSL shall be made, in [*]. The invoices will be issued upon completion of the batches and issuance of the Certificate of Compliance and Certificate of
Analysis for each batch in accordance with Section 9. AFC’s invoice shall be paid by GSL not later than [*] days following the latest of (i) the receipt of the applicable invoice, (ii) expiration of the Acceptance Period,
and (iii) the receipt of the Certificate of Analysis and Certificate of Compliance. Any invoiced amount which is not paid within [*] days of its due date shall be assessed a late payment fee at a rate of [*] or the maximum rate
permitted by applicable law with respect to such obligations, whichever is less.

inventories of the Product pursuant to Section 6 as GSL may determine in its sole discretion. For clarity, but without limitation on other contract damages that may be available in the event of a material breach by a party, in the event the
termination is on grounds of a material breach resulting [*] during the Initial Term, GSL shall pay to AFC [*]. 
  

	 	b)	If either Party becomes bankrupt, the other Party may, with immediate Notice to the first Party, terminate the Agreement with no liabilities whatsoever, subject to
relevant legislation and provisions herein contained. 

  

	 	c)	GSL may terminate this Agreement in whole or in part at any time by giving [*] days written notice to AFC, if GSL, in its sole discretion, determines that
