Common Stock Purchase Agreement



 Exhibit 10.1 
 MANNKIND CORPORATION 
 COMMON STOCK 

PURCHASE AGREEMENT 
 This COMMON STOCK PURCHASE AGREEMENT (this “Agreement”) is made as of the 2nd day of February, 2012 by and between MannKind Corporation, a Delaware corporation (the
“Company”), and The Mann Group LLC (such Purchaser, including its successors and assigns, the “Purchaser”). 
 WHEREAS, subject to the terms and conditions set forth in this Agreement, the Company desires to issue and sell to the Purchaser, and the Purchaser desires to purchase from the Company, 31,250,000 shares
of the Company’s common stock, $0.01 par value (the “Shares”). 
 NOW, THEREFORE, in consideration
of the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Company and the Purchaser agree as follows: 

1. Purchase and Sale of Stock. 
 1.1 Sale and Issuance of Common Stock. On the basis of the representations and warranties herein, and upon the terms and subject to the conditions hereof, the Purchaser agrees to purchase from the
Company and the Company agrees to issue and sell to the Purchaser at the price of $2.47 per share, which is the consolidated closing bid price for the Company’s common stock as reported by The Nasdaq Global Market on February 2, 2012 (the
“Per Share Purchase Price”). 
 1.2 Closing. Subject to the satisfaction or waiver of the
conditions set forth herein, the purchase and sale of the Shares pursuant to this Agreement (the “Closing”) shall take place at the offices of the Company within three business days following the expiration or termination of
the waiting period applicable to the transactions contemplated hereby under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Clearance”) and the Company’s receipt of stockholder approval to
increase the number of the Company’s authorized shares as necessary, or at such later time or place as the Company and the Purchaser may mutually agree. The date on which the Closing actually takes place is referred to herein as the
“Closing Date”. At such time, the Company shall cause its transfer agent to deliver to the Purchaser a certificate representing such Shares against payment therefor, which payment shall be made, at the discretion of the
Company, in the form of (a) cash, by wire transfer of immediately available funds to an account designated by the Company, (b) the cancellation of indebtedness owed by the Company to the Purchaser under that certain Amended and Restated
Promissory Note, dated August 10, 2010, as amended (the “Note”), the amount of such indebtedness cancelled to be equal to the number of Shares not paid for in cash by the Purchaser, if any, multiplied by the Per Share
Purchase Price, or (c) a combination of the foregoing; provided, however, that any cancellation of indebtedness shall be applied only to the outstanding principal balance under the Note and not to any accrued interest. In connection with
any cancellation of indebtedness, the Purchaser shall record an appropriate notation on Exhibit A to the Note to reflect such cancellation as a payment of principal on the Note. 

  
 1. 









 2. Representations and Warranties of the Company. The Company hereby represents and warrants to the
Purchaser that: 
 (a) All corporate action on the part of the Company, its officers, directors and stockholders necessary for
the authorization of this Agreement, the performance of all obligations of the Company hereunder and the authorization, sale, issuance and delivery of the Shares pursuant hereto has been taken. 

(b) This Agreement constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its
terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors’ rights generally and (ii) equitable principles of general
applicability relating to the availability of specific performance, injunctive relief or other equitable remedies. 
 (c)
Assuming the accuracy of the representations and warranties of the Purchaser contained in Section 3 hereof, the offer, sale and issuance of the shares of Common Stock pursuant hereto will be exempt from the registration requirements of the
Securities Act of 1933, as amended (the “Securities Act”), and will have been registered or qualified (or are exempt from registration and qualification) under the registration, permit or qualification requirements of all
applicable state securities laws. 
 3. Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants to
the Company that: 
 (a) The Purchaser has full right, power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement. 
 (b) This Agreement constitutes a valid and binding obligation of the Purchaser enforceable against the Purchaser in accordance with its terms, except as may be limited by (i) applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) equitable principles of general applicability relating to the availability of specific performance,
injunctive relief or other equitable remedies. 
 (c) The Purchaser understands that nothing in this Agreement or any other
materials presented to the Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed
necessary or appropriate in connection with its purchase of the Shares. 
 (d) The Purchaser understands that the shares of
Common Stock to be purchased hereunder have not been registered under the Securities Act. The Purchaser also understands that such shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in
part upon the Purchaser’s representations contained in this Agreement. 

  
 2. 









 (e) The Purchaser has substantial experience in evaluating and investing in private
placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. The Purchaser must bear the
economic risk of this investment indefinitely unless the Shares purchased hereunder are registered pursuant to the Securities Act, or an exemption from registration is available. The Purchaser understands that the Company has no present intention of
registering such Shares. The Purchaser also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow the Purchaser to transfer
all or any portion of such Shares under the circumstances, in the amounts or at the times the Purchaser might propose. 
 (f)
The Purchaser is acquiring the Shares to be purchased hereunder for the Purchaser’s own account for investment only, and not with a view towards their distribution. 
 (g) The Purchaser has the capacity to protect its own interests in connection with the transactions contemplated in this Agreement. 

(h) The Purchaser is an accredited Purchaser within the meaning of Regulation D under the Securities Act. 

4. Covenant of the Purchaser. The Purchaser hereby covenants with the Company to use its reasonable best efforts to cooperate with the Company and
counsel for the Company to obtain the HSR Clearance contemplated by Section 1.2 of this Agreement as soon as reasonably practicable following the date of this Agreement. 
 5. Restrictions on Transfer 
 5.1 Rule 144. The Purchaser
acknowledges and agrees that the Shares to be purchased hereunder are “restricted securities” as defined in Rule 144 promulgated under the Securities Act as in effect from time to time and must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such registration is available. The Purchaser has been advised or is aware of the provisions of Rule 144, which permits limited resale of shares purchased in a private placement
subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number of
shares being sold during any three-month period not exceeding specified limitations. 
 5.2 Restrictive Legend. The
Purchaser acknowledges and agrees that each certificate representing the Shares purchased hereunder shall be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable
state securities laws): 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “ACT”), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, 

  
 3. 









 
ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH
REGISTRATION IS NOT REQUIRED. 
 5.3 Legend Removal. The Company shall be obligated to reissue promptly unlegended
certificates at the request of the Purchaser if the Purchaser shall have obtained an opinion of counsel (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of
may lawfully be so disposed of without registration, qualification and legend. 
 6. Miscellaneous. 

6.1 Successors and Assigns. This Agreement may not be assigned by either party without the prior written consent of the other
party. Subject to the preceding sentence, this Agreement will be binding upon the parties and their respective successors and assigns.

more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile and electronic (PDF) signatures shall be as effective as original signatures. 

6.4 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be

 6.5 Notices. Unless otherwise provided, any notice required
or permitted under this Agreement shall be given in writing and shall be deemed effectively given upon personal delivery to the party to be notified or upon facsimile transmission and by courier service (with proof of service), or by registered or
