 Re: Separation Agreement 

Dear Hakan: 
 This letter supersedes any previous employment,
severance or change of control agreement and sets forth the terms of the transition and separation agreement (the “Agreement”) that MannKind Corporation (the “Company”) is offering to you. 

1. SEPARATION DATE. As we have discussed, your employment termination date will be July 1, 2017, or
such earlier date as your employment may be terminated by either you or the Company pursuant to Section 3 below (the “Separation Date”). 

2. TRANSITION DATE. During the period between now and December 31, 2015 (the
“Transition Date”), you may be required to perform some services transitioning responsibilities to the new or interim Chief Executive Officer. 

3. TRANSITION PERIOD. 

a. Transition Period Duties. During the period between now and the Separation Date (the “Transition Period”), you will
remain an employee of the Company, serving in a non-executive capacity, reporting to the new or interim CEO. You agree that, during the Transition Period, you will comply with all Company policies and procedures and with all of your contractual
obligations to the Company (including, without limitation, your obligations under your Employee Proprietary Information and Inventions Agreement). Your Transition Period duties will include, but are not limited to, providing information to the
Company, as requested. During the Transition Period, you will not be expected to work from the Company’s office locations on a full-time basis, although you will be expected to be available as needed. While you will ordinarily be working from
home during this period, you will receive from the Company such administrative support for your performance of your Company duties as needed. For clarity, during the Transition Period, you are entitled to obtain employment from another employer
provided such employment does not conflict with your then current Transition Period duties and applicable Company policies and procedures. 

b. Standard Compensation/Benefits. During the Transition Period, you will continue to receive your current base salary, subject to
standard withholdings and deductions; you will continue to accrue paid time off (“PTO”) according to Company policy; and you will be eligible for the

Company’s standard benefits, including but not limited to the Company’s Exec-U-Care plan, subject to the terms of such plans and programs and applicable law. On the Separation Date, or
as soon as feasible thereafter, you will receive a final paycheck for all wages earned through the Separation Date (subject to standard withholdings and deductions), and all accrued and unused PTO. Your coverage under the Company’s group health
plan will continue through the Transition Period, and your premiums will be paid by the Company to the extent provided by the Company’s current health insurance policies. If at any time during the Transition Period, you become eligible to
continue your group health benefits at your own expense under the federal COBRA law, or applicable state insurance laws, the Company will pay your monthly COBRA premiums through the Separation Date. Thereafter, to the extent provided by the federal
COBRA law, or applicable state insurance laws, and by the Company’s current health insurance policies, you will be eligible to continue your group health insurance benefits at your own expense. Later, you may be able to convert to an individual
policy through the provider of the Company’s health insurance, if you wish. 
 c. Annual Bonus. During the Transition Period,
you will be eligible to receive an annual bonus for work performed in 2015 (scheduled to be paid in March following the conclusion of the applicable performance year), under the standard bonus plan applicable to Senior Executives. 

d. Stock Options and Restricted Stock Units. You were granted restricted stock units (the “RSUs”) in, and options (the
“Options”) to purchase, shares of the Company’s common stock, pursuant to the Company’s applicable equity incentive plan documents (collectively, the “Plan”) and your Option and RSU grant documents. During
the Transition Period, your Options and RSUs will continue to vest pursuant to the Plan, will continue to be governed by the Plan and applicable grant documents, and will cease vesting as of the Separation Date. Thereafter, your vested Option shares
will be exercisable pursuant to the terms of the Plan and applicable grant documents. You will not receive any additional equity awards during the Transition Period. 

e. Termination for Cause. During the Transition Period, you are entitled to resign from your employment at any time for any reason.
Additionally, during the Transition Period, the Company is entitled to terminate your employment with or without Cause (as defined below). If the Company terminates your employment with Cause during the Transition Period, your employment ends
due to your death or disability, or you resign for any reason, your employment will end immediately and you will not receive any further compensation or benefits from the Company (including the severance payments set forth in Section 4 below),
except for any unpaid salary and PTO accrued through your Separation Date and any vested benefit under a written ERISA-qualified benefit program. 

f. “Cause” Definition. For purposes of this Agreement, “Cause” for termination of your employment will mean
any of the following: (i) your commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably likely to cause injury to the Company; (ii) your unauthorized use or disclosure of any
proprietary information or trade secrets of the Company or any other party in breach of a contractual commitment; (iii) your willful breach of any of your obligations under any written agreement with the Company or any Company policy; or
(iv) your engaging in employment or performing any work activities competitive with the Company. 
 4. SEPARATION
DATE RELEASE AND SEVERANCE PAYMENT. Subject to the terms and conditions set forth in Section 3 (Transition Period), if you remain a Company employee
through July 1, 2017, you remain in compliance with this Agreement and all Company policies, and you sign the Separation Date Release on the Separation Date or within forty-five (45) days thereafter and allow it to become effective,

then the Company will pay you as severance, an amount equal to the average bonus that you received in respect of calendar years 2013, 2014 and 2015 (each of which was paid in March following the
conclusion of the applicable performance year) (the “Severance”). The Severance will be subject to standard employment and income tax deductions and withholdings and will be paid to you in a lump sum on or before the date in 2018 on
which the annual bonuses for work performed in 2017 are paid, or on or within seven (7) days after the effective date of the Separation Date Release, if it occurs later. 

5. OTHER COMPENSATION OR BENEFITS. You acknowledge that,
except as expressly provided in this Agreement, you will not receive any additional compensation, severance, or benefits after the Separation Date. 

6. EXPENSE REIMBURSEMENTS. You agree that, within thirty (30) days after the
Separation Date, you will submit your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any, for which you seek reimbursement. The Company will reimburse such expenses
pursuant to its regular business practice. If you are required to travel before or during the Transition Period or the Consulting Period to discharge your duties or perform Consulting Services, then you shall be subject to the same travel expense
guidelines as apply to Executive Leadership Team members. 
 7. RETURN OF COMPANY
PROPERTY. By the Separation Date, you shall return to the Company all Company documents (and all copies or reproductions thereof) and other Company property within your possession or control, including, but not
limited to, Company hardcopy and electronic files, email, notes, drawings, records, reports, studies, compilations of data, business plans and forecasts, proposals, agreements, financial and operational information, sales and marketing information,
research and development information, product and prototype information, personnel information, specifications, computer-recorded information, tangible property and equipment including, but not limited to, credit cards, entry cards, identification
badges, keys, computing and communication devices; and any materials of any kind that contain or embody any proprietary or confidential information of the Company (and all reproductions or embodiments thereof, in whole or in part). Your timely
return of all such Company documents and other property is a condition precedent to your receipt of the benefits provided under this Agreement; provided that you are permitted to retain copies of any agreement that you signed with the Company (after
leaving with the Company the original or another copy, if you do not possess the original). Your return of property and information shall include return of a copy of any Company information stored on any personal computing device, and deletion of
all such information from your personal devices without retention of any copy or embodiment; and you agree to permit the Company to inspect any such device to ensure that such return and deletion of information has taken place. 

8. PROPRIETARY INFORMATION PROTECTION AND ASSIGNMENT
OF RIGHTS TO WORK PRODUCT. You acknowledge and agree to abide by your continuing obligations under your Employee Proprietary Information and Inventions
Agreement. You further agree that, both during and after your employment, you will make no use or disclosure of any Company proprietary or confidential information unless specifically authorized in writing by a Company officer. You hereby assign to
the Company all right, title, and interest you may have in any and all inventions, developments, concepts, methods, trade secrets, intellectual property, or other work product developed or obtained by you during your employment with the Company that
relates to any actual or anticipated line of business, product, service, or activity of the Company, or your performance of services for the Company, or was produced on Company time or equipment.

 9. CONFIDENTIALITY. The provisions of this Agreement
will be held in strictest confidence by you and the Company and will not be publicized or disclosed in any manner whatsoever; provided, however, that: (a) you may disclose this Agreement in confidence to your immediate family; (b) the
parties may disclose this Agreement in confidence to their respective attorneys, accountants, auditors, tax preparers, and financial advisors; (c) the Company may disclose this Agreement as necessary to fulfill standard or legally required
corporate reporting or disclosure requirements; and (d) the parties may disclose this Agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law. 

10. NONDISPARAGEMENT. You agree not to disparage the Company and its officers, directors, employees, shareholders and
agents, in any manner likely to be harmful to them or their business, business reputations or personal reputations, provided that you may respond accurately and fully to any inquiry to the extent required by legal process. 

11. NO ADMISSIONS. You understand and agree that the promises and payments in
consideration of this Agreement shall not be construed to be an admission of any liability or obligation by the Company to you or to any other person, and that the Company makes no such admission. 

12. RELEASE OF CLAIMS. In exchange for the consideration under this Agreement to which you
would not otherwise be entitled, you hereby generally and completely release the Company and its directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers,
affiliates, and assigns from any and all claims, liabilities and obligations, both known and unknown, arising from or in any way related to events, acts, conduct, or omissions occurring at any time prior to and including the time you sign this
Agreement. This general release includes, but is not limited to: (a) all claims arising from or in any way related to your employment with the Company or the termination of that employment; (b) all claims related to your compensation or
benefits from the Company, including salary, bonuses, commissions, fees, vacation pay, expense reimbursements, severance pay, fringe benefits, stock, stock options, or any other ownership interests in the Company; (c) all claims for breach of
contract, wrongful termination, and breach of the implied covenant of good faith and fair dealing; (d) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation of public policy; and (e) all
federal, state, and local statutory claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with
Disabilities Act of 1990, the California Labor Code (as amended), the California Family Rights Act, the Age Discrimination in Employment Act (“ADEA”), and the California Fair Employment and Housing Act (as amended). Notwithstanding
the foregoing, you are not releasing the Company hereby from any breach of this Agreement subsequent to its Effective Date, or any obligation to indemnify you pursuant to the Articles and Bylaws of the Company, any valid fully executed
indemnification agreement with the Company, applicable law, or applicable directors and officers liability insurance. Also, excluded from this Agreement are any claims that cannot be waived by law. You are not waiving your right to bring proceedings
before administrative agencies such as the Equal Employment Opportunity Commission, Department of Labor, or the California Department of Fair Employment and Housing, provided that you are waiving any monetary recovery from such proceedings. You
represent that you have no lawsuits, claims or actions pending in your name, or on behalf of any other person or entity, against the Company or any other person or entity subject to the release granted in this paragraph.

 13. ADEA RELEASE. You acknowledge that you are knowingly
and voluntarily waiving and releasing any rights you have under the ADEA, and that the consideration given for the waiver and releases you have given in this Agreement is in addition to anything of value to which you were already entitled. You
further acknowledge that you have been advised, as required by the ADEA that: (a) your waiver and release does not apply to any rights or claims that arise after the date you sign this Agreement; (b) you should consult with an attorney
prior to signing this Agreement (although you may choose voluntarily not to do so); (c) you have forty-five (45) days to consider this Agreement (although you may choose voluntarily to sign it sooner); (d) you have seven (7) days
following the date you sign this Agreement to revoke this Agreement (in a written revocation sent to me); and (e) this Agreement will not be effective until the date upon which the revocation period has expired, which will be the eighth day
after you sign this Agreement provided that you do not revoke it (the “Effective Date”). 
 14.
SECTION 1542 WAIVER. In granting the release herein, which includes claims that may be unknown to you at present, you acknowledge that you have read and understand Section 1542 of the
California Civil Code: 
 “A general release does not extend to claims which the creditor does not know or suspect to exist in his or
her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.” 

You hereby expressly waive and relinquish all rights and benefits under that section and any law or legal principle of similar effect in any jurisdiction with
respect to the releases granted herein, including but not limited to the release of unknown and unsuspected claims granted in this Agreement. 

15. DISPUTE RESOLUTION. To aid in the rapid and economical resolution of any disputes
which may arise under this Agreement, you and the Company agree that any and all claims, disputes or controversies of any nature whatsoever arising from or regarding the interpretation, performance, negotiation, execution, enforcement or breach of
this Agreement, your employment, or the termination of your employment, shall be resolved by confidential, final and binding arbitration conducted before a single arbitrator with JAMS, Inc. (“JAMS”) in the Los Angeles, California
area, in accordance with JAMS’ then-applicable arbitration rules, which appear at the following link: http://www.jamsadr.com/rules-comprehensive-arbitration/. The parties acknowledge that by agreeing to this arbitration procedure,
they waive the right to resolve any such dispute through a trial by jury, judge or administrative proceeding. You will have the right to be represented by legal counsel at any arbitration proceeding. The arbitrator shall: (a) have the
authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be available under applicable law in a court proceeding; and (b) issue a written statement signed by the arbitrator regarding
the disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which the award is based. The Company shall bear JAMS’ arbitration fees
and administrative costs. Nothing in this Agreement shall prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such
arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction. 
 16.
REPRESENTATIONS. You hereby represent that you have been paid all compensation owed and for all hours worked; have received all the leave and leave benefits and protections for which you are eligible pursuant to the Family and
Medical Leave Act, the California Family Rights Act, or otherwise, and have not suffered any on-the-job injury for which you have not already filed a workers’ compensation claim.

 17. MISCELLANEOUS. This Agreement, including all exhibits, constitutes
the complete, final and exclusive embodiment of the entire agreement between you and the Company with regard to its subject matter. It is entered into without reliance on any promise or representation, written or oral, other than those expressly
contained herein, and it supersedes any other such promises, warranties or representations, including, but not limited to, your employment offer letter, Executive Severance Agreement and Employee Proprietary Information and Inventions Agreement
(insofar as it may be inconsistent with this Agreement). This Agreement may not be modified or amended except in a written agreement signed by both you and a duly authorized officer of the Company. If any provision of this Agreement (including, but

be deemed modified and enforceable consistent with the intent of the parties insofar as possible under applicable law. This Agreement will be construed and enforced in accordance with the laws of the State of California without respect to conflicts
of law principles. Any ambiguity in this Agreement shall not be construed against either party as the drafter. Any waiver of a breach of this Agreement must be in writing and shall not be deemed a waiver of any successive breach. This Agreement may
be executed in counterparts and facsimile signatures will suffice as original signatures. 
 If this Agreement is acceptable to you, please sign below and
return the original to me. You have forty-five (45) calendar days to decide whether to accept this Agreement, and the Company’s offer contained herein will automatically expire if you do not sign and return it within this timeframe.

 EXHIBIT B 

EMPLOYEE PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT 

 MANNKIND CORPORATION 

EMPLOYEE PROPRIETARY INFORMATION 

AND INVENTIONS AGREEMENT 

In consideration of my employment or continued employment by MANNKIND CORPORATION (the “Company”), and the
compensation now and hereafter paid to me, I hereby agree as follows: 

 

 1. NONDISCLOSURE 

1.1 Recognition of Company’s Rights; Nondisclosure. At all times during my employment and thereafter, I will hold in strictest
confidence and will not disclose, use, lecture upon or publish any of the Company’s Proprietary Information (defined below), except as such disclosure, use or publication may be required in connection with my work for the Company, or unless an
officer of the Company expressly authorizes such in writing. I will obtain Company’s written approval before publishing or submitting for publication any material (written, verbal, or otherwise) that relates to my work at Company and/or
incorporates any Proprietary Information. I hereby assign to the Company any rights I may have or acquire in such Proprietary Information and recognize that all Proprietary Information shall be the sole property of the Company and its assigns. 

1.2 Proprietary Information. The term “Proprietary Information” shall mean any and all confidential and/or
proprietary knowledge, data or information of the Company. By way of illustration but not limitation “Proprietary Information” includes (a) tangible and intangible information relating to antibodies and other biological
materials, cell lines, samples of assay components, media and/or cell lines and procedures and formulations for producing any such assay components, media and/or cell lines, formulations, products, processes, know-how, designs, formulas, methods,
developmental or experimental work, clinical data, improvements, discoveries, plans for research, new products, marketing and selling, business plans, budgets and unpublished financial statements, licenses, prices and costs, suppliers and customers,
and information regarding the skills and compensation of other employees of the Company (hereinafter collectively referred to as “Inventions”); and (b) information regarding plans for research, development, new products,
marketing and selling, business plans, budgets and unpolished financial statements, licenses, prices and costs, suppliers and customers; and (c) information regarding the skills and compensation of other employees of the Company.
Notwithstanding the foregoing, it is understood that, at all such

 
times, I am free to use information which is generally known in the trade or industry, which is not gained as result of a breach of this Agreement, and my own, skill, knowledge, know-how and
experience to whatever extent and in whichever way I wish. 
 1.3 Third Party Information. I understand, in addition, that the
Company has received and in the future will receive from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s part to maintain the confidentiality of such
information and to use it only for certain limited purposes. During the term of my employment and thereafter, I will hold Third Party Information in the strictest confidence and will not disclose to anyone (other than Company personnel who need to
know such information in connection with their work for the Company) or use, except in connection with my work for the Company, Third Party Information unless expressly authorized by an officer of the Company in writing. 

1.4 No Improper Use of Information of Prior Employers and Others. During my employment by the Company I will not improperly use or
disclose any confidential information or trade secrets, if any, of any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto the premises of the Company any unpublished documents or any
property belonging to any former employer or any other person to whom I have an obligation of confidentiality unless consented to in writing by that former employer or person. I will use in the performance of my duties only information which is
generally known and used by persons with training and experience comparable to my own, which is common knowledge in the industry or otherwise legally in the public domain, or which is otherwise provided or developed by the Company. 

2. ASSIGNMENT OF INVENTIONS. 

2.1 Proprietary Rights. The term “Proprietary Rights” shall mean all trade secret, patent, copyright, mask work and
other intellectual property rights throughout the world. 

 

  
 1. 

 2.2 Prior Inventions. Inventions, if any, patented or unpatented, which I made prior to
the commencement of my employment with the Company are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit B (Previous Inventions) attached hereto a complete list of all Inventions
that I have, alone or jointly with others, conceived, developed or reduced to practice or caused to be conceived, developed or reduced to practice prior to the commencement of my employment with the Company, that I consider to be my property or the
property of third parties and that I wish to have excluded from the scope of this Agreement (collectively referred to as “Prior Inventions”). If disclosure of any such Prior Invention would cause me to violate any prior
confidentiality agreement, I understand that I am not to list such Prior Inventions in Exhibit B but am only to disclose a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the fact that full
disclosure as to such inventions has not been made for that reason. A space is provided on Exhibit B for such purpose. If no such disclosure is attached, I represent that there are no Prior Inventions. If, in the course of my employment with
the Company, I incorporate a Prior Invention into a Company product, process or machine, the Company is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights to sublicense through multiple
tiers of sublicensees) to make, have made, modify, use and sell such Prior Invention. Notwithstanding the foregoing, I agree that I will not incorporate, or permit to be incorporated, Prior Inventions in any Company Inventions without the
Company’s prior written consent. 
 2.3 Assignment of Inventions. Subject to Sections 2.4, and 2.6, I hereby assign and agree
to assign in the future (when any such Inventions or Proprietary Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to the Company all my right, title and interest in and to any and all Inventions (and all
Proprietary Rights with respect thereto) whether or not patentable or registrable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the period of my employment
with the Company. Inventions assigned to the Company, or to a third party as directed by the Company pursuant to this Section 2, are hereinafter referred to as “Company Inventions.”

 2.4 Nonassignable Inventions. This Agreement does not apply to an Invention which
qualifies fully as a nonassignable Invention under Section 2870 of the California Labor Code (hereinafter “Section 2870”). I have reviewed the notification on Exhibit A (Limited Exclusion Notification) and agree
that my signature acknowledges receipt of the notification. 
 2.5 Obligation to Keep Company Informed. During the period of my
employment and for six (6) months after termination of my employment with the Company, I will promptly disclose to the Company fully and in writing all Inventions authored, conceived or reduced to practice by me, either alone or jointly with
others. In addition, I will promptly disclose to the Company all patent applications filed by me or on my behalf within a year after termination of employment. At the time of each such disclosure, I will advise the Company in writing of any
Inventions that I believe fully qualify for protection under Section 2870; and I will at that time provide to the Company in writing all evidence necessary to substantiate that belief. The Company will keep in confidence and will not use for
any purpose or disclose to third parties without my consent any confidential information disclosed in writing to the Company pursuant to this Agreement relating to Inventions that qualify fully for protection under the provisions of
Section 2870. I will preserve the confidentiality of any Invention that does not fully qualify for protection under Section 2870. 

2.6 Government or Third Party. I also agree to assign all my right, title and interest in and to any particular Company Invention to
a third party, including without limitation the United States, as directed by the Company. 
 2.7 Works for Hire. I acknowledge
that all original works of authorship which are made by me (solely or jointly with others) within the scope of my employment and which are protectable by copyright are “works made for hire,” pursuant to United States Copyright Act (17
U.S.C., Section 101). 
 2.8 Enforcement of Proprietary Rights. I will assist the Company in every proper way to obtain, and
from time to time enforce, United States and foreign Proprietary Rights relating to Company Inventions in any and all countries. To that end I will execute, verify and deliver such documents and perform such other acts (including appearances as a
witness) as the Company may reasonably request for use in applying for, obtaining, perfecting, evidencing, sustaining and enforcing such Proprietary Rights and

 

  
 2. 

 
the assignment thereof. In addition, I will execute, verify and deliver assignments of such Proprietary Rights to the Company or its designee. My obligation to assist the Company with respect to
Proprietary Rights relating to such Company Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after my termination for the time actually spent by me
at the Company’s request on such assistance. 
 In the event the Company is unable for any reason, after reasonable effort, to secure my signature on
any document needed in connection with the actions specified in the preceding paragraph, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, which appointment is

complete and exclusive agreement of the parties with respect to the subject matter hereof and supersedes and merges all prior discussions between us. No modification of or amendment to this Agreement, nor any waiver of any rights under this
Agreement, will be effective unless in writing and signed by the party to be charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement. 

This Agreement shall be effective as of the first day of my employment with the Company, namely: April 20, 2001.
