Ladies and Gentlemen:

MannKind Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co., ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“▇▇▇▇▇▇▇ ▇▇▇▇▇”) and ▇.▇. ▇▇▇▇▇▇ Securities Inc. (“JPMorgan”, together with ▇▇▇▇▇▇▇ ▇▇▇▇▇, the “Underwriters”), $100,000,000 aggregate principal amount of its 3.75% Senior Convertible Notes due 2013 (the “Notes”), and with respect to the grant by the Company to the Underwriters, acting severally and jointly, of the option described in Section 2(a) hereof to purchase all or any part of an additional $15,00,000 aggregate principal amount of Notes to cover over-allotments, if any. The aforesaid $100,000,000 principal amount of the Notes to be purchased by the Underwriters (the “Initial Securities”) and all or any part of the $15,000,000 aggregate principal amount of Notes subject to the option described in Section 2(a) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.” The Securities will be issued pursuant to an Indenture dated November 1, 2006, as amended by that first supplement to the indenture, dated as of the Closing Date (the “Indenture”), between the Company and ▇▇▇▇▇ Fargo Bank, N.A., as trustee (the “Trustee”). Securities issued in book-entry form will be issued to Cede & Co. as nominee of The Depository Trust Company (“DTC”) pursuant to a letter agreement, to be dated as of the Closing Time (as herein) (the “DTC Agreement”), among the Company, the Trustee and DTC.

The Securities are convertible into shares of common stock, par value $0.01 per share, of the Company (the “Underlying Common Stock”) in accordance with the terms of the Securities and the Indenture, at the initial conversion price set forth on Annex E.

Concurrent with the offering and sale of the Securities by the Company pursuant to the terms of this Agreement, the Company is offering to sell up to 23,000,000 shares of its common stock (including the underwriters’ over-allotment) (the “Shares”), pursuant to the terms of a Purchase Agreement, dated of even date herewith, among the Company, JPMorgan, ▇▇▇▇▇▇▇ ▇▇▇▇▇, CIBC World Markets Corp., Leerink Swan & Co., Inc. and Wachovia Securities (the “Concurrent Equity Offering”). The offering, issuance and sale of the Securities by the Company pursuant to the terms of this Agreement are not contingent on the successful completion of the Concurrent Equity Offering.

The Company hereby confirms its agreement with the Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement (File No. 333-138373), including a prospectus, relating to the Securities and other securities of the Company. Such registration statement was declared effective on November 7, 2006. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before it became effective, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness, together with any prospectus supplement filed with the Commission pursuant to Rule 424(b) under the Securities Act, that omits Rule 430 Information, and the term “Prospectus” means the prospectus, together with any prospectus supplement filed pursuant to Rule 424(b) under the Securities Act, in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.

Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated November 27, 2006, and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex D hereto and the pricing information set forth on Annex E.

2. Purchase of the Securities by the Underwriters. (a) The Company agrees to issue and sell the Securities to the Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective aggregate principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 97% of the principal amount thereof (the “Purchase Price”) plus accrued interest, if any, from December 6, 2006, to the Closing Date.

In addition, the Company agrees to issue and sell up to $15,000,000 principal amount of Option Securities to the Underwriters at the Purchase Price plus accrued interest, if any, from the Closing Date to the date of payment and delivery, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Securities at the Purchase Price.

If any Option Securities are to be purchased, the number of Option Securities to be purchased by each Underwriter shall be the number of Option Securities which bears the same ratio to the aggregate principal amount of Securities being purchased as the aggregate principle amount of Initial Securities set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 10 hereof) bears to the aggregate principal amount of Initial Securities being purchased from the Company by the Underwriters, subject, however, to such adjustments to eliminate any fractional Securities as the Underwriters in their sole discretion shall make.

The Underwriters may exercise the option to purchase the Option Securities at any time in whole, or from time to time in part, on or before the thirtieth day following the date of this Agreement, by written notice from the Underwriters to the Company. Such notice shall set forth the aggregate number of Option Securities as to which the option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date (as hereafter defined) but shall not be earlier than the Closing Date nor later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the

Underwriters is advisable, and initially to offer the Securities on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(c) Payment for the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the Underwriters for the Initial Securities, at the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ at 10:00 A.M. New York City time on December 12, 2006, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Underwriters and the Company may agree upon in writing or, in the case of the Option Securities, on the date and at the time and place specified by the Underwriters in the written notice of the Underwriters’ election to purchase such Option Securities. The time and date of such payment for the Initial Securities is referred to herein as the “Closing Date” and the time and date for such payment for the Option Securities, if other than the Closing Date, is herein referred to as the “Additional Closing Date.”

Payment for the Securities to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the Underwriters for their respective accounts of the Securities to be purchased on such date in definitive form registered in such names and in such denominations as the Underwriters shall request in writing not later than two full business days prior to the Closing Date or the Additional Closing Date, as the case may be, with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. The certificates for the Securities will be made available for inspection and packaging by the Underwriters at the office of ▇▇▇▇▇▇▇ ▇▇▇▇▇ set forth above not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(d) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, the reasonable legal fees and other reasonable expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information (including any Time of Sale Information that has subsequently been amended) or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading or (iii) any untrue statement or alleged untrue statement of a material fact included in any materials or information provided to investors by, or with the written approval of, the Company in connection with the marketing of the offering of the Securities, including any road show or investor presentations made to the investors by the Company (whether in person or electronically), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, when taken together with the Time of Sale Information, in the light of the circumstances under which they are made, not misleading; provided, however, that in the case of each of clause (i) and (ii) above, except insofar as such losses, claims,

damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information (including any Time of Sale Information that has subsequently been amended), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the first paragraph under the caption “Underwriting—Commissions and Discounts,” and the information contained under the caption “Underwriting—Price Stabilization and Short Positions.”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such

separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by each of the Underwriters and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same respective proportions as the net proceeds (after deducting underwriting discounts and commissions but before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the Underwriters, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Underwriters, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Underwriters, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the

terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate principal amount of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase aggregate principal amount of Securities that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the aggregate principal amount of Securities that such Underwriter agreed to purchase on such date) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and

delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing this Agreement; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Underwriters may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the National Association of Securities Dealers, Inc.; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to the listing of the Securities on the Nasdaq Global Market.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

Annex A

Form of Opinion of Counsel for the Company

1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware with requisite corporate power to own or lease, as the case may be, and to operate its properties and conduct its business as described in the Time of Sale Information and the Prospectus.

2. The Company is duly qualified to do business as a foreign corporation and is in good standing under the laws of the states identified on Exhibit A hereof.

3. The Notes are in a form contemplated by the Indenture, have been duly authorized, executed and delivered by the Company and, when authenticated by the Trustee in accordance with the terms of the Indenture and issued and delivered against payment of the purchase price thereof, will constitute valid and binding obligations of the Company, subject, as to enforcement, by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, by general principles of equity and limitations on availability of equitable relief, including specific performance (regardless of whether such enforceability is considered in a proceeding in equity or at law).

4. Upon issuance and delivery of the Notes in accordance with the Agreement and the Indenture against payment of the purchase price thereof, the Notes shall be convertible at the option of the holder thereof for the Shares in accordance with the terms of the Notes and the Indenture.

5. The Shares issuable upon conversion of the Notes have been duly authorized and reserved for issuance and, when so issued and delivered upon such conversion in accordance with the terms of the Indenture, will be validly issued, fully paid and nonassessable.

6. The holders of outstanding shares of capital stock of the Company are not entitled to preemptive or, to our knowledge, rights of first refusal or other similar rights to subscribe for the Shares.

7. To our knowledge, there is no action, suit or proceeding by or before any court or other governmental agency, authority or body or any arbitrator pending or overtly threatened against the Company or its properties by a third party of a character required to be disclosed in the Time of Sale Information or the Prospectus that is not disclosed in the Time of Sale Information or the Prospectus as required by the Securities Act and the rules thereunder.

8. To our knowledge, there is no indenture, contract, lease, mortgage, deed of trust, note agreement, loan or other agreement or instrument of a character required to be filed as an exhibit to the Registration Statement, which is not filed as required by the Securities Act and the rules thereunder.

9. The statements in (i) the Prospectus under the headings “Description of Common Stock” (other than the first paragraph thereof) and “Description of Notes” and (ii) Item 15 in the Registration Statement, insofar as such statements purport to summarize legal matters, agreements or documents discussed therein, fairly present, to the extent required by the Securities Act and the rules thereunder, in all material respects, such legal matters, agreements or documents. The statements in Part II, Item 1 of the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2006, filed with the Commission on November 2, 2006, insofar as such statements constitute summaries of the proceedings described therein, fairly summarize the matters referred to therein in all material respects. The statements in the Prospectus under the heading “Material U.S. Federal Income Tax Consequences,” to the extent that they constitute matters of U.S. federal income tax laws and legal conclusions with respect thereto, are accurate in all material respects.

10. The Registration Statement has become effective under the Securities Act; no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or overtly threatened. Any required filing of the Prospectus, and any supplement thereto, pursuant to Rule 424(b) under the Securities Act, has been made in the manner and within the time period required by Rule 424(b).

11. The Registration Statement, the Preliminary Prospectus, the Prospectus, and documents incorporated by reference in the Prospectus set forth therein under the heading “Incorporation by Reference” (other than the financial statements and notes thereto or other financial or statistical data derived therefrom, as to which we express no opinion) comply as to form in all material respects with the applicable requirements of the Securities Act and the rules thereunder.

12. The Agreement has been duly authorized by all necessary corporate action on the part of the Company and has been duly executed and delivered by the Company.

13. The Indenture has been duly authorized by all necessary corporate action on the part of the Company and has been duly executed and delivered by the Company and, constitutes a legally valid and binding agreement of the Company enforceable against the Company in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, by general principles of equity and limitations on availability of equitable relief, including specific performance (regardless of whether such enforceability is considered in a proceeding in equity or at law). The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

14. The Company is not, and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus, will not be, an “investment company” as defined in the Investment Company Act.

15. No consent, approval, authorization or filing with or order of any U.S. Federal or California court or governmental agency or body having jurisdiction over the Company is required for the consummation by the Company of the transactions contemplated by the Agreement, except such as have been obtained under the Securities Act and except such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters in the manner contemplated in the Agreement and in the Prospectus, or under the bylaws, rules and regulations of the NASD.

16. The issue and sale of the Securities pursuant to the Agreement and the Indenture will not result in a breach or violation of (i) any Material Contract, (ii) the charter or bylaws of the Company or (iii) to our knowledge, any statute, law, rule, or regulation which, in our experience is typically applicable to transactions of the nature contemplated by the Agreement and the Indenture and is applicable to the Company, or any order, writ, judgment, injunction, decree, or award that has been entered against the Company and of which we are aware, in each case the breach or violation of which would materially and adversely affect the Company.

***********************

In connection with the preparation of the Registration Statement, Time of Sale Information and the Prospectus, we have participated in conferences with officers and other representatives of the Company, with its certified public accountants and with ▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇▇, LLP and ▇▇▇▇▇, ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇, P.C., as well as with representatives of the Underwriters and their counsel. At such conferences, the contents of the Registration Statement, Time of Sale Information and the Prospectus and related matters were discussed. We have not independently verified, and accordingly are not confirming and assume no responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement, Time of Sale Information or the Prospectus. On the basis of the foregoing, no facts have come to our attention that have caused us to believe (i) that the Registration Statement (except as to the financial statements and schedules, related notes and other financial data and statistical data derived therefrom, as to which we express no comment), at the date and time that the Registration Statement became effective, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) that the Time of Sale Information (except as to the financial statements and schedules, related notes and other financial and statistical data derived therefrom, as to which we express no comment) as of the Time of Sale contained any untrue statement of a material fact or omitted to state a material fact necessary, in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) that the Prospectus (except as to the financial statements and schedules, related notes and other financial and statistical data derived therefrom, as to which we express no comment) as of its date or dates as amended or supplemented, if applicable, and as of the date hereof contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary, in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

This opinion is intended for the sole benefit of the several Underwriters and may not be made available to or relied upon by any other person, firm or entity without our prior written consent. This opinion is limited to the matters expressly set forth in this letter, and no opinion has been implied, or may be inferred, beyond the matters expressly stated. This opinion speaks only as to law and facts in effect or existing as of the date hereof and we undertake no obligation or responsibility to update or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention or any changes in any law that may hereafter occur.

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

This opinion letter is being furnished to you at the request of Mannkind Corporation, a Delaware corporation (the “Company”), pursuant to Section 6(h) of the Underwriting Agreement dated December ___, 2006 between you and the Company (the “Underwriting Agreement”), relating to the public offering by the Company of shares of the Company’s common stock, par value $0.01 per share (the Offering”). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.

We have been retained by the Company to act as U.S. Food and Drug Administration (“FDA”) regulatory counsel for the limited purpose of reviewing the information relating to FDA regulatory matters contained in certain sections of the Company’s (i) Registration Statement on Form S-3 (File No. 333-138373), which was filed with the Securities and Exchange Commission (“SEC”) on November 2, 2006 (the “Registration Statement”), (ii) the prospectus filed with the SEC on November 8, 2006 (the “Base Prospectus”), (iii) the preliminary prospectus supplement filed with the SEC on November 27, 2006 (the “Preliminary Prospectus Supplement” and, together with the Base Prospectus, the“ Preliminary Prospectus”) and (iv) the prospectus supplement filed with the SEC on December [6], 2006 (the “Prospectus Supplement,” and together with the Base Prospectus, the “Prospectus”) specified below. We have not been retained by the Company or anyone else to pass upon any other information in the Registration Statements or Prospectus, nor have we represented the Company in connection with other matters. For purposes of this opinion letter, “FDA Laws”, laws that we specialize in, shall mean the Federal Food, Drug, and Cosmetic Act (the “FDC Act”) set forth at 21 U.S.C. § 301 et seq. and the regulations promulgated under the authority of the FDC Act, each as amended, and the enforcement of the FDC Act by the FDA.

In connection with this opinion letter, we have made such legal and factual examinations and inquiries as we have deemed necessary or appropriate for the purposes of this opinion. In that regard, we have requested from the Company all documents and information material to

disclosures regarding FDA regulatory matters, and have received, reviewed and relied upon only the following:

1. Information in the Registration Statement and Prospectus, and documents incorporated therein by reference, pertaining to FDA regulatory matters under the following captions (collectively referred to herein as the “Designated Regulatory Provisions”): “Prospectus Supplement Summary — Mannkind Corporation — Overview”; “Prospectus Supplement Summary — Mannkind Corporation — Recent Developments”; “Risk Factors — Certain risks related to regulatory approvals - Our product candidates must undergo rigorous preclinical and clinical testing and we must obtain regulatory approvals, which could be costly and time consuming and subject us to unanticipated delays or prevent us from marketing any products”; “Business — Overview”; “Business – Clinical Development Activities”; “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Clinical Development Activities”; “Business – Government Regulation and Product Approval”; “Risk Factors — Risks Related to Our Business — We depend heavily on the successful development and commercialization of our lead product candidate, the Technosphere Insulin System, which is still under development, and our other product candidates, which are in preclinical development”; “Risk Factors — Risks Related to Our Business — Testing of Our Technosphere Insulin System or another product candidate may not yield successful results, and even if it does, we may still be unable to commercialize that product candidate”; Risk Factors — Risks Related to Our Business — If we are unable to transition successfully from an early stage development company to a company that commercializes therapeutics, our operations would suffer”; “Risk Factors — Risks Related to Our Business — We have never manufactured our Technosphere Insulin System or any other product candidate in commercial quantities, and if we fail to develop an effective manufacturing capability for our product candidates or to engage third-party manufacturers with this capability, we may be unable to commercialize these products”; “Risk Factors — Risks Related to Regulatory Approvals.”

2. The Officer’s Certificate, dated December ___, 2006, signed by ▇▇▇▇▇ ▇▇▇▇▇▇▇, Ph.D., ▇.▇., Corporate Vice President, General Counsel and Corporate Secretary, certifying certain facts relating to the Company (the “Officer’s Certificate”) and attached here as Attachment A.

3. Copies of the documents listed in Attachment B, which were provided to us by the Company and which the Company identified as responsive to our request for all material documents pertaining to the Designated Regulatory Provisions.

4. Representations made to us during discussions with Mr. ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇ ▇▇▇▇, ▇▇. ▇▇▇▇▇▇ Boss, and ▇▇. ▇▇▇▇ ▇▇▇▇▇▇ during the period November 21-26, 2007.

We have assumed with your approval the accuracy and completeness of all statements of fact relating to the Company and the status of its products and, except as set forth above, you have not asked us to make, and we have not made, any independent investigations with regard to such matters for purposes of rendering the opinions herein. We have also assumed the accuracy and completeness of all documents and records that we have reviewed, the genuineness of all signatures, the authenticity of the documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as certified, conformed or

reproduced copies. We have further assumed that with respect to the laws identified above, all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies or self regulatory bodies, applicable to this opinion letter, are generally available to lawyers practicing in the area of the FDA laws and are in a format that makes legal research reasonably feasible.

Further, we have not independently verified, nor do we take any responsibility for, or are we in any way addressing, any statements of belief attributable to the Company or whether or not the Company is in compliance with the FDA Laws.

This opinion is based solely on matters of law as they pertain to FDA Laws, as implemented by FDA, and we express no opinion as to any other federal, state, local or foreign laws, statutes, regulations or ordinances.

Based on, subject to, and limited by the foregoing, we are of the opinion that:

(i) Insofar as the statements in the Designated Regulatory Provisions purport to describe or summarize applicable provisions of the FDA Laws, such statements are accurate in all material respects, subject to any qualifications set forth therein; and

(ii) Nothing has come to our attention which causes us to believe that the Designated Regulatory Provisions,

	a.		In the Registration Statement on [insert date RS became effective] and at all times subsequent thereto up to and on the Closing Date, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

	b.		In the Preliminary Prospectus [include any other prospectuses filed with the SEC before or on the date of the UW agreement that include FDA information and that HPM has an opportunity to review] as of the date of the Underwriting Agreement, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and

	c.		In the Prospectus as of [insert date of final prospectus] and as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

* * * *

This opinion letter is given as of the date hereof and we assume no obligation to advise you of any changes in the foregoing subsequent to the delivery of this opinion. This opinion is solely for the information of the addressee hereof and is not to be quoted in whole or in part or

otherwise referred to, nor is it to be filed with any governmental agency or any other person without our prior written consent. No one other than the addressee hereof is entitled to rely on this opinion. This opinion is rendered solely for purposes of the Offering and should not be relied upon for any other purpose. Nothing herein should be construed to cause us to be considered “experts” within the meaning of Section 11 of the Securities Act of 1933, as amended.

Sincerely,

▇▇▇▇▇, ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇, P.C.

OFFICER’S CERTIFICATE

Annex C

Form of Opinion of Special Intellectual Property Counsel for the Company


		Re:		Purchase of up to [17,500,000 shares of Common Stock (the “Shares”)] [$100,000,000 principal amount of ___% Senior Convertible Notes due 2013 (the “Notes”) of MannKind Corporation by the Underwriters pursuant to the Underwriting Agreement dated ___, 2006

Ladies and Gentlemen:

We have acted as special counsel to MannKind Corporation, a Delaware corporation (the “Company”), with respect to certain intellectual property matters as further described below. This opinion is being delivered pursuant to Section 6(i) of the Underwriting Agreement dated December ___, 2006 (the “Underwriting Agreement”), between the Company and you, as representatives of the several underwriters named in Schedule A to the Underwriting Agreement (the “Underwriters”). Unless specifically defined herein or unless the context requires otherwise, capitalized terms used herein shall have the meanings set forth in the Underwriting Agreement.

Our role with respect to the intellectual property matters of the Company is limited to legal representation concerning inventions, patents, patent applications and trade secrets relating to the Company’s cancer therapy research and diketopiperazine drug delivery devices (as each is described in the Registration Statement and Prospectus), an analysis of certain patent law issues relating to U.S. Patent Nos. 5,506,203, 5,518,998, 5,997,848, 6,395,774, 6,663,898 and 6,737,045 and rendering opinions to the Company with respect thereto, and a review of the disclosures in the Registration Statement, the Time of Sale Information and the Prospectus with respect to other intellectual property matters of the Company. We have not audited the Company’s trademarks.

In connection with the preparation of this opinion, we have examined such documents and considered such questions of law as we have deemed necessary or appropriate. We have assumed the authenticity of all documents submitted to us as originals, the conformity with originals of all documents submitted to us as copies, and the genuineness of all signatures. We have also assumed the legal capacity of all natural persons and that, with respect to all parties to agreements or instruments relevant hereto, such parties had the requisite power and authority to execute, deliver and perform such agreements or instruments, that such agreements or instruments have been duly authorized by all requisite action, executed and delivered by such parties, and that such agreements or instruments are the valid, binding and enforceable obligations of such parties.

Whenever a statement herein is qualified by “known to us,” “to our current actual knowledge,” or similar phrase, it is intended to indicate that no attorney who has rendered substantive legal services to the Company relating to intellectual property matters and is currently employed by our firm has any conscious awareness of facts or other information which indicates that any of the opinions contained herein are untrue. However, except as otherwise expressly indicated, we

have not undertaken any independent investigation to determine the accuracy of such statement, and any limited inquiry undertaken by us during the preparation of this opinion letter should not be regarded as such an investigation; no inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company.

Based upon the foregoing, and subject to the additional assumptions, exceptions, qualifications and limitations set forth below, we are of the opinion that:

1. To our knowledge, (i) there are no legal or governmental proceedings pending relating to patent rights, trade secrets, copyrights, trademarks, service marks of the Company or its subsidiaries, and (ii) no such proceedings are threatened or contemplated by governmental authorities or others.

2. To our knowledge, (i) except as disclosed in the Registration Statement, the Time of Sale Information and the Prospectus and specifically with respect to U.S. Patent Nos. 5,506,203, 5,518,998, 5,997,848, 6,395,774, 6,663,898 and 6,737,045, neither the Company nor its subsidiaries are infringing or otherwise violating any claim of an issued patent of a third party (including, without limitation, U.S. Patent Nos. 6,214,804, 6,331,318, 6,413,942 and 6,685,967), or the rights of any third party in trade secrets, copyrights, trademarks or service marks, and, upon commercialization of the products in the form presently in clinical trials described in the Registration Statement, the Time of Sale Information and the Prospectus, neither the Company nor its subsidiaries would be infringing or otherwise violating any claim in a currently issued patent or published patent application of a third party or the rights of any third party in trade secrets, copyrights, trademarks or service marks, and (ii) there are no infringements by any third party or any patent of the Company or its subsidiaries, or the rights of the Company or its subsidiaries in trade secrets, copyrights, trademarks or service marks which in our judgment could materially affect the Company’s use thereof.

3. For the reasons set forth in opinions delivered to the Company we are of the opinion that U.S. Patent Nos. 5,506,203, 5,518,998, 5,997,848, 6,395,774 6,663,898, and 6,737,045 are invalid and unenforceable as to the Company’s product candidates in the form presently in clinical trials.

4. Based solely upon a review of the Company’s internal files and publicly available records in the USPTO, the Company or a Subsidiary is the record owner of the patents referenced in the Registration Statement and the Prospectus as owned by the Company. We are unaware of any third party, including any academic institution or governmental entity, that has any ownership interest in any patents, trade secrets, copyrights, trademarks or service marks that are owned by the Company or its subsidiaries.

5. We are unaware of any facts which would form a basis for a finding of unenforceability or invalidity of any of the Company’s or any of its subsidiaries’ patents (including upon commercialization of the product candidates in the form presently in clinical trials described in the Registration Statement, the Time of Sale Information and the Prospectus).

6. To our knowledge, the patents and patent applications of the Company and its subsidiaries which encompass the product candidates in the form presently in clinical trials described in the Registration Statement, Time of Sale Information and the Prospectus disclose or claim patentable subject matter under United States patent laws.

7. We and, to our knowledge, the Company and its subsidiaries, have complied with the required duty of candor and good faith in dealing with the USPTO and foreign patent offices in connection with the patents and patent applications of the Company and its subsidiaries, including the duty to disclose all information believed to be material to the patentability thereof.

8. We are unaware of any material fact with respect to the patent applications of the Company or any of its subsidiaries presently on file in the USPTO or foreign patent offices that (i) would preclude the issuance of patents with respect to such applications, or (ii) would lead us to conclude that such patents, when issued, would not be valid and enforceable in accordance with applicable regulations (including upon commercialization of the product candidates in the form presently in clinical trials described in the Registration Statement, the Time of Sale Information and the Prospectus).

9. Except as disclosed in the Registration Statement, we are not aware that the Company lacks or will be unable to obtain any rights to use all Intellectual Property necessary to the conduct of its business as now operated by it, except where the failure to own or possess or otherwise be able to acquire such Intellectual Property rights would not, singly or in the aggregate, have a Material Adverse Effect.

10. We have reviewed the statements made in the Company’s Form 10-K for the year ended December 31, 2005 under the heading “Business—Intellectual Property and Proprietary Technology” and in the Company’s Form 10-Q for the quarter ended September 30, 2006 under the heading “Risk Factors—Risks Related to Intellectual Property” and, insofar as such statements constitute a summary of the Company’s Intellectual Property, they fairly and accurately summarize in all material respects the legal matters, documents and proceedings relating to such Intellectual Property described therein.

Although we have not undertaken to investigate or verify independently and are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information and the Prospectus (other than those specific matters on which we are opining in paragraph 10 hereof), and based solely upon on the examinations and inquiries described in the forepart of this letter, and the limitations inherent in the examination made by us and the knowledge available to us, we can advise you supplementally as a matter of fact and not as an opinion that nothing has come to our attention that causes us to believe that the Intellectual Property matters in:

(i) the Registration Statement, at the time such Registration Statement became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(ii) the Time of Sale Information as of the date of the Underwriting Agreement, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and

(iii) the Prospectus as of its date and as of the date hereof, contained or contains an untrue statement of material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

We do not purport to be experts on or to be qualified to express any opinion herein concerning, nor do we express any opinion herein concerning, any law other than the laws of the State of California and the federal law of the United States.

This opinion is furnished to you in connection with the transactions contemplated by the Underwriting Agreement and is solely for the benefit of you and the several Underwriters, and may not be relied upon by any other person or for any other purpose without our prior written consent. This opinion speaks only as of the date above written, and we hereby expressly disclaim any duty to update any of the statements made herein.

Very truly yours,

Re: MannKind Corporation – Public Offering (Notes)

Ladies and Gentlemen:

The undersigned understands that each of you propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with MannKind Corporation, a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by you (the “Underwriters”) of Senior Convertible Notes of the Company (the “Securities”). The Securities will be convertible into shares of common stock, $0.01 par value per share (the “Common Stock”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of your agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co., ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“▇▇▇▇▇▇▇ ▇▇▇▇▇”) and ▇.▇. ▇▇▇▇▇▇ Securities Inc. (“JPMorgan”), the undersigned will not, during the period commencing on the date hereof and ending 90 days after the date of the Underwriting Agreement, (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the

undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.
