portion of this Note pursuant to Section 2 shall be determined according to the following formula (the “Conversion Rate”): 

            Conversion
Amount             
 Conversion Price 

(c) Mechanics of Conversion. The conversion of this Note shall be conducted in the following manner: 

(i) Holder’s Delivery Requirements. To convert a Conversion Amount into Conversion Shares on any date (the “Conversion
Date”), the Holder shall (A) transmit by facsimile or electronic mail (or otherwise deliver), for receipt on or prior to 5:00 p.m. New York City time on such date, a copy of an executed conversion notice in the form attached hereto as
Exhibit A (the “Conversion Notice”) to the Company (Attention: Matthew Pfeffer, Fax: (661) 775-2099, Email: mpfeffer@mannkindcorp.com), and (B) if required by Section 2(c)(vi),
surrender to a common carrier for delivery to the Company, no later than three (3) Business Days after the Conversion Date, the original Note being converted (or an indemnification undertaking in customary form with respect to this Note in the
case of its loss, theft or destruction). 
 (ii) Company’s Response. Upon receipt or deemed receipt by the Company of a copy of
a Conversion Notice, the Company (I) shall immediately send, via facsimile, a confirmation of receipt of such Conversion Notice to the Holder and the Company’s designated transfer agent (the “Transfer Agent”), which
confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein and (II) on or before the second (2nd) Business Day
following the date of receipt or deemed receipt by the Company of such Conversion Notice (the “Share Delivery Date”) (A) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program and provided that the Holder is eligible to receive Shares through DTC, credit such aggregate number of Conversion Shares to which the Holder shall be entitled to the Holder’s or its designee’s
balance account with DTC through its Deposit Withdrawal Agent Commission system, or (B) if the foregoing shall not apply, issue and deliver to the address as specified in the Conversion Notice, a stock certificate, registered in the name of the
Holder or its designee, for the number of Conversion Shares to which the Holder shall be entitled. If notwithstanding the provisions of Section 2(c)(vi), the Holder elects to physically surrender this Note for conversion and the
Principal represented by this Note is greater than the Principal being converted, then the Company shall, as soon as practicable and in no event later than three (3) Business Days after receipt of this Note (the “Note Delivery
Date”) and at its own expense, issue and deliver to the Holder a new Note representing the Principal not converted and cancel this Note. The Conversion Shares will be freely transferable and will not contain a legend restricting the resale
or transferability of the Conversion Shares if the Unrestricted Conditions (as defined below) are met. 
 (iii) Dispute Resolution.
In the case of a dispute as to the determination of the Conversion Price or the arithmetic calculation of the Conversion Rate, the Company shall instruct the Transfer Agent to issue to the Holder the number of Conversion


  
 5 








 
Shares that is not disputed and shall transmit an explanation of the disputed determinations or arithmetic calculations to the Holder via facsimile within two (2) Business Days of receipt or
deemed receipt of the Holder’s Conversion Notice or other date of determination. If the Holder and the Company are unable to agree upon the determination of the Conversion Price or arithmetic calculation of the Conversion Rate within one
(1) Business Day of such disputed determination or arithmetic calculation being transmitted to the Holder, then the Company shall promptly (and in any event within two (2) Business Days) submit via facsimile (A) the disputed
determination of the Conversion Price to an independent, reputable investment banking firm agreed to by the Company and the Required Note Holders, or (B) the disputed arithmetic calculation of the Conversion Rate to the Company’s
independent registered public accounting firm, as the case may be. The Company shall direct the investment bank or the accounting firm, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the
results no later than two (2) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accounting firm’s determination or calculation, as the case may be, shall be binding upon all
parties absent manifest error. 
 (iv) Record Holder. The person or persons entitled to receive the Conversion Shares issuable upon
a conversion of this Note shall be treated for all purposes as the legal and record holder or holders of such Shares on the Conversion Date, or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is
subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section 2(c)(iii), the first Business Day after the resolution of such bona fide
dispute and the fees and expenses of such investment bank or accountant shall be paid by the Company. 
 (v) Company’s Failure to
Timely Convert. 
 (A) Cash Damages. If within three (3) Business Days after the Company’s receipt of the facsimile or
electronic mail copy of a Conversion Notice or deemed receipt of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder for, or credit the Holder’s or its designee’s balance account with DTC with, the
number of Conversion Shares (free of any restrictive legend if the Unrestricted Conditions (as defined below) are met) to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount (a “Delivery Failure”)
then in addition to all other available remedies that the Holder may pursue hereunder and under the Facility Agreement, the Company shall pay additional damages to the Holder for each day after the Share Delivery Date such conversion is not timely
effected in an amount equal to one percent (1%) of the product of (I) the number of Conversion Shares not issued to the Holder or its designee on or prior to the Share Delivery Date and to which the Holder is entitled and (II) the Volume
Weighted Average Price of the Common Stock on the Share Delivery Date (such product is referred to herein as the “Share Product Amount”) Alternatively in lieu of the foregoing damages, subject to Section 2(c)(iii), at
the written election of the Holder made in the Holder’s sole discretion, if, on or after the applicable Conversion Date, the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a
sale by such Holder of Conversion Shares that such Holder anticipated receiving from the Company (such purchased shares, “Buy-In Shares”), the Company shall be obligated to promptly pay to such Holder (in addition to all
other available 

  
 6 








 
remedies that the Holder may otherwise have), 107.5% of the amount by which (A) such Holder’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares
exceeds (B) the net proceeds received by such Holder from the sale of the number of shares equal to up to the number of Conversion Shares such Holder was entitled to receive but had not received on such Share Delivery Date. If the Company fails
to pay the additional damages set forth in this Section 2(c)(v)(A) within five (5) Business Days of the date incurred, then the Holder entitled to such payments shall have the right at any time, so long as the Company continues to fail to
make such payments, to require the Company, upon written notice, to immediately issue, in lieu of such cash damages, the number of Shares equal to the quotient of (X) the aggregate amount of the damages payments described herein divided by
(Y) the Conversion Price specified by the Holder in the Conversion Notice. 
 (B) Void Conversion Notice. If for any reason the
Holder has not received all of the Conversion Shares prior to the tenth (10th) Business Day after the Share Delivery Date with respect to a conversion of this Note (a “Conversion Failure”), then the Holder, upon written notice
to the Company (a “Void Conversion Notice”), may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to the Holder’s
Conversion Notice; provided, that the voiding of the Holder’s Conversion Notice shall not affect the Company’s obligations to make any payments that have accrued prior to the date of such notice pursuant to
Section 2(c)(v)(A) or otherwise. 
 (vi) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon
conversion or repayment of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless all of the Principal is being converted or repaid. The Holder and the Company shall
maintain records showing the Principal converted or repaid and the dates of such conversions or repayments or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note
upon any such partial conversion or repayment. Notwithstanding the foregoing, if this Note is converted or repaid as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder may request, representing in the aggregate the remaining Principal represented by this Note. The Holder and any assignee, by
acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion or repayment of any portion of this Note, the Principal of this Note may be less than the principal amount stated on the face
hereof. 
 (d) Taxes. The Company shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes levied on
gross earnings, profits or the like of the Holder) that may be payable with respect to the issuance and delivery of Conversion Shares upon the conversion of this Note, unless the tax is due because the Holder requests any Conversion Shares to be
issued in a name other than the Holder’s name, in which case the Holder will pay that tax. 

  
 7 








 (e) Legends. 

(i) Restrictive Legend. The Holder understands that this Note and until such time as the Conversion Shares have been registered under
the Securities Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of
securities as of a particular date that can then be immediately sold, the Conversion Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the
certificates for such securities): 
 THE SECURITY REPRESENTED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
OR APPLICABLE STATE SECURITIES LAWS. THIS SECURITY MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN
EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULE 144 UNDER SAID ACT.” 
 (ii) Removal of
Restrictive Legends. The certificates evidencing the Conversion Shares shall not contain any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)): (A) while a registration statement (including
a Registration Statement, as defined in the Registration Rights Agreement) covering the resale of such security by the Holder is effective under the Securities Act, (B) following any sale of such Conversion Shares pursuant to Rule 144, or
(C) if such Conversion Shares are eligible for sale under rule 144(b)(1) and the Holder thereof is not, and has not been during the preceding three months, an affiliate (as such term is defined for purposes of Rule 144 under the Securities Act)
(the “Unrestricted Conditions”). The Holder agrees that the removal of the restrictive legend from the Conversion Shares in accordance with the immediately preceding sentence is predicated upon the Company’s reliance that
(i) the Holder will dispose of such shares pursuant to the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or for its own account in compliance with Rule 144, and that if such
securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein, and (ii) if, prior to the disposition of any such Conversion Shares, the Company notifies the Holder that
the Unrestricted Conditions have no longer been met, the Holder will agree to the placement of said restrictive legend on the certificates for such Conversion Shares until the Unrestricted Conditions have once again been met. Promptly following the
Effective Date (as defined below) or such other time as any of the Unrestricted Conditions have been satisfied, the Company shall cause its counsel to issue a legal opinion or other instruction to the Transfer Agent (if required by the Transfer
Agent) to effect the issuance of the Conversion Shares without a restrictive legend or, in the case of Conversion Shares that have previously been issued, the removal of the legend thereunder. If the Unrestricted Conditions are met at the time of
issuance of the Conversion Shares, then the Conversion Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as the Unrestricted Conditions are met or such legend is otherwise no longer
required under this Section 2(e), it will, no later than four (4) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the Company or the Transfer Agent of any certificate
representing Conversion Shares, as applicable, issued with a 

  
 8 








 
restrictive legend (such fourth Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Holder a certificate (or electronic transfer) representing such
shares that is free from all restrictive and other legends. For purposes hereof, “Effective Date” shall mean the date that the Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement
has been declared effective by the SEC. 
 (iii) Sale of Unlegended Shares. Holder agrees that the removal of the restrictive legend
from any certificates representing securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell any Conversion Shares pursuant to either the registration requirements of the
Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth
therein. 
 (f) Limitations on Conversions. 

(i) Beneficial Ownership. Notwithstanding anything herein to the contrary, the Company shall not issue to the Holder, and the Holder
may not acquire, a number of Shares upon conversion of this Note or otherwise issue any shares of Common Stock pursuant hereto or the Facility Agreement to the extent that, upon such conversion, the number of Shares then beneficially owned by the
Holder and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group”
of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth
herein) would exceed 9.985% of the total number of shares of Common Stock then issued and outstanding (the “9.985% Cap”), provided, however, that the 9.985% Cap shall only apply to the extent that the Common Stock is deemed to
constitute an “equity security” pursuant to Rule 13d-1(i) promulgated under the Exchange Act, and provided, further, that if the Holder and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would
be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act beneficially own on the Issuance Date greater than 9.985% of the shares of Common Stock then outstanding, then the 9.985% Cap shall not apply to such Holder
unless and until the beneficial ownership of the Holder and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act
subsequently decreases to below 9.985%. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Securities and
Exchange Commission (“SEC”), and the percentage held by the Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the written request of the Holder, the Company shall,
within two (2) Trading Days, confirm orally and in writing to the Holder the number of Shares then outstanding. 
 (ii) Principal
Market Regulation. The Company shall not issue any Shares upon conversion of this Note (including pursuant to Section 2(c)(v)(A) hereof) if the issuance of such Shares together with any previous issuances of Shares under the Notes would
exceed 57,885,577 (the “Exchange Cap”), except that such limitation shall not apply in the 

  
 9 








 
event that the Company obtains the approval of its stockholders as required by the applicable rules of The Nasdaq Global Market and any other Principal Market for issuances of Shares in excess of
such amount. 
 (iii) Applicable Limits on Conversion of the Note. Notwithstanding anything to the contrary herein, (A) unless
otherwise agreed to by the Company, this Note shall not be convertible, and the Company shall not issue Shares upon conversion of this Note, as a Conversion Price less than $5.00 per Share, [and unless the Tranche 3 Notes have been converted in
full]2, (B) this Note shall not be convertible, and the Company shall not issue Shares upon conversion of this Note, if the number of shares that would otherwise be issuable upon such
conversion, together with all shares previously issued upon conversion of all Notes or issuable upon conversion of any other Notes converted on the same Conversion Date, exceeds 30 million shares (subject to appropriate adjustment to reflect
any Stock Event), and (C) this Note shall not be convertible, and the Company shall not issue Shares upon conversion of this Note, if the number of shares that would otherwise be issuable upon such conversion, together with any shares issuable
upon conversion of any other Notes converted on the same Conversion Date, exceeds the then Applicable Limit. For purposes herein, “Applicable Limit” shall initially mean (x) 30 million Shares (subject to appropriate adjustment to
reflect any Stock Event) for all conversions of Notes at a “Conversion Price” of $3.33 (subject to appropriate adjustment to reflect any Stock Event) or less, (y) 15 million Shares (subject to appropriate adjustment to reflect
any Stock Event) for all conversions of Notes at a “Conversion Price” of $6.67 (subject to appropriate adjustment to reflect any Stock Event) or more, and (z) $100 million of “Conversion Amounts” for all Note conversions at
a “Conversion Price” of between $3.33 and $6.67 (subject to appropriate adjustment to reflect any Stock Event); provided, however, that, after each Conversion Date, the Applicable Limit under all three clauses (regardless of which clause
such conversion relates to) shall be reduced by an amount equal to the Applicable Limit immediately preceding such conversion multiplied by a fraction, the numerator of which is the number of Shares actually converted on such date (in the case of
clauses (x) and (y)) or the applicable “Conversion Amount” for all shares actually converted on such date (in the case of clause (z)) and the denominator of which is the Applicable Limit in respect of the clause under which such
conversion falls immediately prior to such conversion. For purposes of illustration: (a) If 15 million shares are converted under any Notes at $3.00 per share, the Applicable Limit shall be reduced by one-half to 15 million,
7.5 million and $50 million, respectively; (b) If an additional $10 million are then converted under any Notes at $5.00 per Share, each Applicable Limit shall then be further reduced by 20% to 12 million, 6 million and $40
million, respectively. As an additional illustration, if 10 million shares are converted under any Notes at $8.00 per share, each Applicable Limit shall be reduced by two-thirds to 10 million, 5 million and $33,333,333, respectively;
and (b) if an additional 500,000 shares are then converted under any Notes at $5.00 per share, each Applicable Limit shall be further reduced by 7.5% to $9,250,000, $4,625,000 and $30,833,333, respectively. 

3. Registration Failures. Upon any Registration Failure, in addition to all other available remedies that the Holder may pursue
hereunder and under the Facility Agreement and the Registration Rights Agreement, the Company shall pay additional damages to the Holder for 

 

	2 	 Include bracketed language in the Tranche 1 Notes only. 



  
 10 








 
each 30-day period (prorated for any partial period) after the date of such Registration Failure in an amount in cash equal to one percent (1%) of such Holder’s original principal
amount of this Note on the date of such Registration Failure. Such payments shall accrue until the earlier of (i) such time as the Registration Failure has been cured and (ii) the date on which all of the Conversion Shares may be disposed
of for such Holder’s own account without restriction under Rule 144 (including, without limitation, volume restrictions and without the need for the availability of current public information under Rule 144), assuming that the Holder is not,
and has not been during the preceding three months, an affiliate (as such term is defined for purposes of Rule 144 under the Securities Act) of the Company. All such payments that accrue under this Section (4) shall be payable no later than
five business days following such date of accrual. 
 4. Voting Rights. Except as required by law, the Holder shall have no voting
rights with respect to any of the Conversion Shares until the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion Shares the issuance of which is subject to a bona
fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section 2(c)(iii), the first Business Day after the resolution of
such bona fide dispute). 
 5. Amendment; Waiver. The terms and provisions of this Note shall not be amended or waived except
in a writing signed by the Company and the Holder. 
 6. Remedies, Characterizations, Other Obligations, Breaches and Injunctive
Relief. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note, the Facility Agreement, at law or in equity (including a decree of specific performance and/or other injunctive
relief). No remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy, and nothing herein shall limit the Holder’s right to pursue actual damages for any failure by the Company to comply with

the like (and the computation thereof) shall be the amounts to be received by the Holder thereof and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or
threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

7. Specific Shall Not Limit General; Construction. No specific provision contained in this Note shall limit or modify any more general
provision contained herein. This Note shall be deemed to be jointly drafted by the Company and all purchasers of Notes pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof. 

8. Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege

 Exhibit C 

FORM OF OPINION 

            , 20     

[                    ] 

 

	Re:	Mannkind Corporation (the “Company”) 

 Dear Sir: 

[            ]
(“[            ]”) intends to transfer its Senior Secured Convertible Note in the principal amount of $            
(the “Note”) of the Company to              (“            ”) without registration under the Securities Act of
1933, as amended (the “Securities Act”). In connection herewith, we have examined such documents and issues of law as we have deemed relevant. 

Based on and subject to the foregoing, we are of the opinion that the transfer of the Note by
             to              may be effected without registration under the Securities Act, provided, however, that the Note to
be transferred to             contain a legend restricting its transferability pursuant to the Securities Act and that transfer of the Note is subject to a stop order. 

The foregoing opinion is furnished only to
                     and may not be used, circulated, quoted or otherwise referred to or relied upon by you for any purposes other than the purpose
for which furnished or by any other person for any purpose, without our prior written consent. 
 Very truly yours,
