MannKind Corporation

Phantom Stock Award Agreement

     Pursuant to the Phantom Stock Award Grant Notice (“ Grant Notice ”) and this Phantom Stock Award Agreement (“ Agreement ”), MannKind Corporation (the “ Company ”) has awarded you Phantom Stock pursuant to Section 7(b) of the MannKind Corporation 2004 Equity Incentive Plan (the “ Plan ”) for the number of shares of Phantom Stock as indicated in the Grant Notice (collectively, the “ Award ”). Defined terms not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan.

     The details of your Award are as follows.

      1. Consideration. Consideration for this Award is satisfied by your services to the Company.

      2. Vesting . Subject to the limitations contained herein, your Award will vest as provided in the Grant Notice. Notwithstanding the foregoing, if you elect to defer receipt of the shares of Common Stock equal to the number of vested shares of Phantom Stock pursuant to Section 3 of this Agreement, then any shares of Phantom Stock subject to this Award that would otherwise vest within the 12-month period following the date of such election shall instead vest on the date that is 12 months following the date of your election to defer.

      3. Distribution of Shares of Common Stock . The Company will deliver to you a number of shares of the Company’s Common Stock equal to the number of vested shares of Phantom Stock subject to your Award, on the vesting date or dates provided in your Grant Notice; provided however, that if the first vesting date occurs no sooner than 12 months following the Date of Grant specified in your Grant Notice and if, within the 30-day period following the Date of Grant indicated on your Grant Notice, you elect to defer delivery of such shares of Common Stock beyond the vesting date, then the Company will deliver the shares of Common Stock to you on the date or dates that you so elect (the “ Settlement Date ”). If such deferral election is made, the Board (or appropriate committee thereof) will, in its sole discretion, establish the rules and procedures for such deferrals.

      4. Certain Adjustments . In the event of any change in the capitalization of the Company, such as by stock dividend, stock split, combination of shares, exchange of securities, recapitalization or other event which the Board deems, in its sole discretion, to be similar circumstances, the Board (or appropriate committee thereof) may make such adjustments to the number and/or kind of shares of stock or securities subject to this Award and any other provision of this Award affected by such change, as the Board may determine in its sole discretion.

      5. Conditions to Delivery of shares of Common Stock . Notwithstanding any other provision of this Agreement or the Plan, the Company will not be obligated to deliver any shares of Common Stock pursuant to this Agreement (i) until all conditions to the Award have been satisfied or removed, (ii) until, in the opinion of counsel to the Company, all

applicable Federal and state laws and regulations have been complied with, (iii) if the outstanding Common Stock is at the time listed on any stock exchange or included for quotation on an inter-dealer system, until the shares of Common Stock to be delivered have been listed or included or authorized to be listed or included on such exchange or system upon official notice of notice of issuance, (iv) if it might cause the Company to issue or sell more shares of Common Stock that the Company is then legally entitled to issue or sell, and (v) until all other legal matters in connection with the issuance and delivery of such shares have been approved by counsel to the Company.

      6. Transferability. Your Award is not transferable, except by will or by the laws of descent and distribution. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, will thereafter be entitled to receive any distribution of shares of Common Stock pursuant to Section 4 of this Agreement.

      7. Award not a Service Contract . Your Award is not an employment or service contract, and nothing in your Award will be deemed to create in any way whatsoever any obligation on your part to continue in the service of the Company or a subsidiary, or on the part of the Company or a subsidiary to continue such service. In addition, nothing in your Award will obligate the Company or a subsidiary, their respective stockholders, boards of directors or Employees to continue any relationship that you might have as an Employee of the Company or a subsidiary.

      8. Unsecured Obligation . Your Award is unfunded, and as a holder of vested Phantom Stock, you will be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares of Common Stock pursuant to this Agreement. You will not have voting or any other rights as a stockholder of the Company with respect to the shares of Common Stock subject to your Award until such shares of Common Stock are issued to you pursuant to Section 4 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

      9. Withholding Obligations.

           (a) On or before the time you receive a distribution of shares of Common Stock pursuant to your Award, or at any time thereafter as requested by the Company, you hereby authorize any required withholding from, at the Company’s election, the shares of Common Stock, payroll and any other amounts payable to you and otherwise agree to make adequate provision for any sums required to satisfy the Federal, state, local and foreign tax withholding obligations of the Company or a subsidiary, if any, which arise in connection with your Award.

           (b) Unless the tax withholding obligations of the Company and/or any subsidiary are satisfied, the Company will have no obligation to issue a certificate for such shares of Common Stock.

      10. Notices . All notices with respect to the Plan shall be in writing and shall be hand delivered or sent by first class mail or reputable overnight delivery service, expenses prepaid. Notice may also be given by electronic mail or facsimile and shall be effective on the date transmitted if confirmed within 24 hours thereafter by a signed original sent in a manner provided in the preceding sentence. Notices to the Company or the Board shall be delivered or sent to the Company’s headquarters to the attention of its Corporate Secretary. Notices to any Participant or holder of shares of Common Stock issued pursuant to an Award shall be sufficient if delivered or sent to such person’s address as it appears in the regular records of the Company or its transfer agent.

      11. Headings . The headings of the Sections in this Agreement are inserted for convenience only and will not be deemed to constitute a part of this Agreement or to affect the meaning of this Agreement.

Notwithstanding the foregoing, this Agreement may be amended solely by the Board (or appropriate committee thereof) by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to you, and provided that no such amendment adversely affecting your rights hereunder may be made without your written consent. Without limiting the foregoing, the Board (or appropriate committee thereof) reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change will be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided herein.

      13. Miscellaneous.

           (a) The rights and obligations of the Company under your Award will be transferable by the Company to any one or more persons or entities, and all covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns.

           (c) All obligations of the Company under the Plan and this Agreement will be binding on any successor to the Company, whether the existence of such successor is the result
