FOR VALUE RECEIVED, Borrower hereby promises to pay to Lender, in lawful
money of the United States of America and in immediately available funds, the principal sum of up to Two Million Six Hundred Thirty Thousand Seven Hundred fifty Dollars ($2,630,750), due and payable on the Maturity Date. 

1. Maturity; Repayment. 

1.1 Maturity. The outstanding principal amount of this Note shall be due and payable on June 30, 2020; provided that
if such date is not a Business Day, the outstanding principal amount of this Note, together with all accrued and unpaid interest thereon, shall be payable on the Business Day immediately succeeding such date (the “Maturity
Date”). 
 1.2 Repayment. Borrower shall pay this Note in lawful money of the United States of America and in
immediately available funds or, at its option, in validly issued, fully paid and non-assessable shares of Common Stock (the “New Shares”), so long as each of the Equity Conditions are
satisfied on each day during the Equity Conditions 

 Measuring Period applicable to such Payment Date. In respect of payments to be made in New Shares, Borrower
shall deliver a written notice (which may be provided via e-mail) (such notice, a “Payment Notice”) to Lender on or prior to the fifth Trading Day prior to the applicable payment date
(such payment date, a “Payment Date”), which Payment Notice shall be irrevocable and shall specify the amount of this Note (the “Payment Amount”) to be paid in New Shares, together with an
officer’s certificate certifying that the Equity Conditions with respect to such payment in New Shares have been met as of the applicable Payment Date. Notwithstanding anything herein to the contrary, if the Equity Conditions fail to have been
met as of the applicable Payment Date, the applicable Payment Amount shall be payable in cash. 
 Any payments of this Note to paid with New
Shares, shall be paid in a number of validly issued, fully paid and non-assessable shares of Common Stock equal to the quotient of (1) the Payment Amount payable on such Payment Date less any such payment
paid in cash, divided by (2) the Last Reported Sale Price on the Trading Day immediately prior to the applicable Payment Date. If the issuance of New Shares would result in the issuance of a fraction of a share of Common Stock, Borrower shall
round such fraction of a share of Common Stock to the nearest whole share (with 0.5 being rounded up). When any New Shares are to be issued, Borrower shall (i) (A) provided that Borrower’s stock transfer agent is participating in the DTC
Fast Automated Securities Transfer Program, upon the request of Lender, credit such aggregate number of New Shares to which Lender shall be entitled to Lender or its designee’s balance account with DTC through its Deposit/Withdrawal at
Custodian system, or (B) if the stock transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, or upon request of Lender, issue and deliver to Lender no later than the second (2) Business Day after the
applicable Payment Date certificates registered in the name of Lender for the number of New Shares to which Lender shall be entitled, (C) deposit such New Shares with the Depositary in accordance with the Applicable Procedures (as defined in
the Indenture), or (D) otherwise deliver the applicable New Shares in accordance with procedures reasonably acceptable to the Lender.

3. Prepayment. This Note may be prepaid in whole or in part without penalty or premium. 

4. Principal Amount. As of the date hereof, the principal amount of this Note is Two Million Six Hundred Thirty Thousand Seven Hundred
Fifty Dollars ($2,630,750). At the time of prepayment of this Note, Lender shall make or cause to be made, an appropriate notation on Exhibit A attached hereto reflecting the amount of such prepayment. The outstanding amount of this Note set
forth on Exhibit A shall be prima facie evidence of the principal amount thereof outstanding, but the failure to record, or any error in so recording, shall not limit or otherwise affect the obligations of Borrower to make payments of
principal of or interest on this Note when due. 
 5. Representations and Warranties. Borrower hereby represents
and warrants to Lender as follows: 
 5.1 Borrower has the requisite power and authority to enter into this Note and to consummate
the transactions contemplated hereby. The execution and delivery of this Note by Borrower and the consummation by Borrower of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Borrower.
This Note has been duly executed and delivered by Borrower and constitutes the legal, valid and binding agreement of Borrower enforceable against Borrower in accordance with its terms, except as may be limited by (i) applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) equitable principles of general applicability relating to the availability of specific performance,
injunctive relief or other equitable remedies. 
 5.2 No consent, approval, authorization, order, license, registration or
qualification of or with any Governmental Entity is required for the execution and delivery by Borrower of this Note or the transactions contemplated hereby, except such consents, approvals, authorizations, orders, licenses, registrations or
qualifications as have been obtained, or which, if not obtained, would not, individually or in the aggregate, have a material adverse effect on the ability of Borrower to perform its obligations hereunder or consummate the transactions contemplated
hereby on a timely basis. As used in this Note, the term “Governmental Entity” means any agency, bureau, commission, authority, department, official, political subdivision, tribunal or other instrumentality of any government,
whether (i) regulatory, administrative or otherwise (including, without limitation, a self-regulatory organization or stock exchange); (ii) federal, state or local; or (iii) domestic or foreign. 

5.3 The execution and delivery by Borrower of this Note, the performance by Borrower of its obligations hereunder, and the consummation
by Borrower of the transactions contemplated hereby, will not conflict with or result 

  
 2 

 
in a breach or violation of (i) any of the terms or provisions of, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which Borrower or any of its subsidiaries is a party or by which Borrower or any
of its subsidiaries is bound or to which any of their property or assets is subject or (ii) any applicable law or statute or any order, rule or regulation of any Governmental Entity having jurisdiction over Borrower or any of its subsidiaries
or any of their respective properties, except for in the case of either clause (i) or (ii) such conflicts, breaches or violations that would not prevent or delay the consummation of the transactions contemplated by this Note or that would
not be reasonably expected to have a material adverse effect on Borrower, nor will any such action result in any violation of the provisions of the organizational documents of Borrower. 

5.4 All of the New Shares, when issued in accordance with the terms of this Note, will be duly authorized and duly and validly issued,
fully paid and nonassessable, free and clear of all liens, taxes, adverse claims, and will not be issued in violation of, or subject to, any preemptive or similar rights of any Person.

Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date hereof (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, being
collectively referred to herein as the “SEC Reports”). None of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Borrower is not in violation of the requirements of the NASDAQ Stock Market (“NASDAQ”) and has no knowledge
of any facts or circumstances which could reasonably be expected to lead to delisting or suspension of the Common Stock in the foreseeable future.

this Note or the issuance of the New Shares by Borrower pursuant hereto will be exempt from the registration requirements of the Securities Act (and such issuances will be or have been registered or qualified (or are exempt from registration and

 5.8 Neither Borrower, nor any of its
Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, has made or will make any offers or sales of any security, or has solicited or will solicit any offers to buy any security, under circumstances that would cause
the offering and issuance of the New Shares to be integrated with prior offerings by Borrower for purposes of the Securities Act and which would require the registration of any such securities under the Securities Act. 

6. Representation and Warranties of Lender. Lender hereby represents and warrants to Borrower as follows: 

6.1 Lender has full right, power and authority to enter into this Note and to consummate the transactions contemplated hereby and has
taken all necessary action to authorize the execution, delivery and performance of this Note.

in private placement transactions of securities in companies similar to Borrower so that it is capable of evaluating the merits and risks of the Securities and has the capacity to protect its own interests. Lender must bear the economic risk of the

present intention of registering any of the Securities. Lender also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow
Lender to transfer all or any portion of any of the Securities under the circumstances, in the amounts or at the times Lender might propose.

distribution.

 THIS PROMISSORY NOTE (this
“Note”), dated as of August 6, 2019, is issued pursuant to the certain Exchange Agreement, dated as of August 6, 2019, by and between MANNKIND
CORPORATION, a Delaware corporation (“Borrower”), and BRUCE FUND, INC. (“Lender”).

 FOR VALUE RECEIVED, Borrower hereby promises to pay to Lender, in
lawful money of the United States of America and in immediately available funds, the principal sum of up to Two Million Six Hundred Thirty Thousand Seven Hundred fifty Dollars ($2,630,750), due and payable on the Maturity Date. 

1. Maturity; Repayment. 

1.1 Maturity. The outstanding principal amount of this Note shall be due and payable on December 31, 2020; provided that if
such date is not a Business Day, the outstanding principal amount of this Note, together with all accrued and unpaid interest thereon, shall be payable on the Business Day immediately succeeding such date (the “Maturity
Date”). 
 1.2 Repayment. Borrower shall pay this Note in lawful money of the United States of America and in
immediately available funds or, at its option, in validly issued, fully paid and non-assessable shares of Common Stock (the “New Shares”), so long as each of the Equity Conditions are
satisfied on each day during the Equity Conditions 

 
Measuring Period applicable to such Payment Date. In respect of payments to be made in New Shares, Borrower shall deliver a written notice (which may be provided via e-mail) (such notice, a “Payment Notice”) to Lender on or prior to the fifth Trading Day prior to the applicable payment date (such payment date, a “Payment Date”),
which Payment Notice shall be irrevocable and shall specify the amount of this Note (the “Payment Amount”) to be paid in New Shares, together with an officer’s certificate certifying that the Equity Conditions with

 Any payments of this Note to paid with New Shares, shall be paid in a number of validly issued, fully paid and non-assessable shares of Common Stock equal to the quotient of (1) the Payment Amount payable on such Payment Date less any such payment paid in cash, divided by (2) the Last Reported Sale Price on the
Trading Day immediately prior to the applicable Payment Date. If the issuance of New Shares would result in the issuance of a fraction of a share of Common Stock, Borrower shall round such fraction of a share of Common Stock to the nearest whole

licenses, registrations or qualifications as have been obtained, or which, if not obtained, would not, individually or in the aggregate, have a material adverse effect on the ability of Borrower to perform its obligations hereunder or consummate the
transactions contemplated hereby on a timely basis. As used in this Note, the term “Governmental Entity” means any agency, bureau, commission, authority, department, official, political subdivision, tribunal or other
instrumentality of any government, whether (i) regulatory, administrative or otherwise (including, without limitation, a self-regulatory organization or stock exchange); (ii) federal, state or local; or (iii) domestic or foreign.

others any rights of termination, amendment, acceleration or cancellation of, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which Borrower or any of its subsidiaries is a party or by which Borrower or any

collectively referred to herein as the “SEC Reports”). None of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in

Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, has made or will make any offers or sales of any security, or has solicited or will solicit any offers to buy any security, under circumstances that would cause
