RECITALS: 
 WHEREAS,
MannKind and Amphastar entered into the Agreement pursuant to which Amphastar is to manufacture and supply the Product to MannKind, and MannKind is to purchase certain minimum quantities of the Product; 

WHEREAS, MannKind and Amphastar are concurrently entering into a first amendment to the Insulin Purchase Option Agreement originally dated
January 1, 2015 (the “Option Amendment”) and 
 WHEREAS MannKind and Amphastar have determined it to be mutually beneficial
to amend the Agreement as set forth herein. 
 NOW, THEREFORE, for good and valuable consideration, MannKind and Amphastar, hereby agree to
amend the Agreement as follows: 
 1. Definitions. Unless otherwise defined herein, each of the capitalized terms used in this Second
Amendment shall have the definition and meaning ascribed to it in the Agreement. 
 2. Amendments to the Agreement. 

2.1 The following sentence in Section 5.1 of the Agreement: 

“Upon delivery to MannKind, AFP shall ensure Product will have a remaining expiry date of not less than four (4) years.”

“In calendar year 2017 and 2018, upon delivery to MannKind, Amphastar shall ensure that Product will have a remaining expiry date of not
less than two (2) years. In calendar year 2019 and the remainder of the term of the Agreement, Amphastar shall ensure Product will have a remaining expiry date of not less than three (3) years.”

“Purchase Commitment and Purchase Price. MannKind shall purchase from AFP the minimum quantities of Product (the
“Purchase Commitment Quantities”) at the purchase price per gram (the “Purchase Price”) in each calendar year as provided in the table set forth below. In the event that MannKind fails to meet the
Purchase Commitment Quantities in any given calendar year, MannKind shall pay AFP for the difference in the amount of the Purchase Commitment Quantities and the actual amount purchased for the corresponding calendar year (such difference, the
“Purchase Commitment Difference”). AFP shall issue an invoice and MannKind shall pay the Purchase Commitment Difference no later than thirty (30) days after the close of the corresponding calendar year.”

issue an invoice and MannKind shall pay the Payment Commitment Difference no later than thirty (30) days after the close of the corresponding calendar quarter. Notwithstanding the foregoing, the parties hereby agree that the Purchase Commitment

fourth (4th) quarter of 2017 but no later than November 15, 2017.

 2.4 Section 6.2 of the Agreement shall be amended and replaced in its
entirety with the following: 
 6.2 Payment. In calendar year 2017 and 2018, MannKind shall pre-pay Amphastar for the Product at least
ten (10) days prior to the estimated delivery date. For the avoidance of doubt, Amphastar shall not ship the Product to MannKind until such payment is received. Beginning in 2019 and for the remainder of the term of the Agreement, MannKind

2.5 A new Section 6.5 shall be added to the Agreement as follows: 

6.5 Right of First Refusal in China. In consideration of the amendments contained in this Second Amendment and in the Option Amendment,
MannKind hereby grants Amphastar the right of first refusal to participate in the development and commercialization of Afrezza in China through a collaborative arrangement. Specifically, Amphastar and MannKind agree that MannKind will not commence
the process of obtaining approval of Afrezza in China without first providing Amphastar with (i) at least ninety (90) days prior written notice of MannKind’s intention to commence the process of obtaining approval of Afrezza in China,
and (ii) if Amphastar confirms its interest in collaborating in the development or commercialization of Afrezza in China in writing within thirty (30) days of receipt of MannKind’s notice, then the Parties shall reserve sixty
(60) days to negotiate in good faith the terms of such a collaborative arrangement for Afrezza in China. In the event that the Parties are unable to agree on commercial terms for a collaborative agreement after the sixty (60) day
negotiation period, then MannKind shall have the right to negotiate a collaborative agreement with another party (“Competing Terms”). MannKind shall present the Competing Terms to Amphastar in writing, and within sixty (60) days of
receipt of the Competing Terms, Amphastar shall have the option to either (i) decline to match the Competing Terms, or (ii) agree to match the same Competing Terms and enter into a collaborative agreement with MannKind in China. 

2.6 Section 10.1 of the Agreement shall be extended until December 31, 2023. All other terms and conditions in
paragraph 10.1 shall remain in full force and effect. 
 3. Final Agreement. 

From and after the execution of this Second Amendment, all references in the Agreement (or in the Second Amendment) to “this
Agreement,” “hereof,” “herein,” “hereto,” and similar words or phrases shall mean and refer to the Agreement as amended by this Second Amendment. The Agreement as amended by this Second Amendment constitutes the
entire agreement by and between the Parties as to the subject matter hereof. Except as expressly modified by this Second Amendment, all other terms and conditions of the Agreement shall remain in full force and effect.
