(including all schedules and exhibits hereto), nor the Ancillary Agreements (including all exhibits, annexes and schedules thereto), nor any report, certificate or instrument furnished to the Purchasers or its counsel in connection with the
transactions contemplated by this Agreement when read together, contains any untrue statement of a material fact or, to the Company’s knowledge, omits to state a material fact necessary in order to make the statements contained herein or
therein, in light of the circumstances under which they were made, not misleading. 
 3.22 Brokers. Except as set forth in
Schedule 3.22, the Company has not retained any finder or broker in connection with the transactions contemplated by this Agreement and agrees to indemnify and save the Purchasers harmless from and against any and all claims,
liabilities or obligations with respect to brokerage or finders’ fees or commissions in connection with the transactions contemplated by this Agreement asserted by any Person on the basis of any agreement, statement or representation alleged to
have been made by the Company. 

  
 -10-









 3.23 Third Party Consents. Except as set forth in Schedule 3.23, to the
Company’s knowledge, no consent or approval is needed from any third party in order to effect the issuance and sale of the Shares (and the Common Stock issuable upon conversion of the Shares) or any of the other transactions contemplated by
this Agreement (including schedules and exhibits hereto) and the Ancillary Agreements. 
 4. REPRESENTATIONS AND WARRANTIES OF THE
PURCHASERS. Each of the Purchasers represents and warrants to the Company, on behalf of itself and not on behalf of the others, as follows: 
 4.1 Accredited Investor. Such Purchaser is an “accredited investor” within the meaning of Rule 501(a) under the Securities Act, and understands that the Company has relied upon its
being an accredited investor in deciding to proceed with the transactions contemplated hereby, and in ascertaining the requirements of law applicable to the issuance and sale of the Shares. The Purchaser’s financial condition is such that the
Purchaser is able to bear all economic risks of investment in the Shares, including a complete loss of the Purchaser’s investments therein. The Purchaser acknowledges that the Company has provided it with adequate access to financial and other
information concerning the Company as requested and that it has had the opportunity to ask questions of and receive answers from the Company concerning the transactions contemplated under this Agreement and the Ancillary Agreements and to obtain
therefrom any additional information necessary to make an informed decision regarding an investment in the Company. 
 4.2
Investment. The Purchaser is acquiring the Shares, and the shares of Series A Common Stock into which the Shares may be converted, for its own account for investment and not with a view to, or for sale in connection with, any distribution
thereof, nor with any present intention of distributing or selling the same; and, except as contemplated by this Agreement and the Ancillary Agreements, the Purchaser has no present or contemplated agreement, undertaking, arrangement, obligation,
indebtedness or commitment providing for the disposition thereof. 
 4.3 Authority. The Purchaser has full power and
authority to enter into and to perform this Agreement and the Ancillary Agreements in accordance with their respective terms. The Purchaser represents that it has not been organized, reorganized or recapitalized specifically for the purpose of
investing in the Company. This Agreement and the Ancillary Agreements have been duly executed and delivered by the Purchaser and constitute valid and binding obligations of each enforceable against it in accordance with their respective terms. The
execution of and performance of the transactions contemplated by this Agreement and the Ancillary Agreements and compliance with the respective provisions thereof by each of the Purchasers will not, to its knowledge, violate any provision of law
and, if applicable, will not conflict with or result in any material breach of any of the terms, conditions or provisions of or constitute a material default under, or require a consent or waiver under, its organizational documents (if any, and each
as amended to date and as in effect as of the date hereof) or any indenture, lease, agreement or other instrument to which the Purchaser is a party or by which it or any of its properties (whether tangible or intangible) is bound, or any decree,
judgment, order, statute, rule or regulation applicable to the Purchaser. 

  
 -11-









 4.4 Unregistered Securities. The Purchaser acknowledges and agrees that the Shares, and any
shares issuable upon conversion thereof, must be held indefinitely until such time as they are subsequently registered under the Securities Act or an exemption from such registration is available. The Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act, which currently permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of
certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being through an unsolicited “broker’s transaction” or in
transactions directly with a market maker (as such term is defined under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) and the number of shares being sold during any three-month period not exceeding specified
limitations. 
 4.5 Principal Place of Business. The address of the residence or the principal place of business, as
applicable, the latter of which is the office in which the Purchaser’s investment decision was made, is accurately set forth on Attachment 1. 
 4.6 Brokers. The Purchaser has not retained any finder or broker in connection with the transactions contemplated by this Agreement and the Purchaser separately agrees to indemnify and save
the Company harmless from and against any and all claims, liabilities or obligations with respect to brokerage or finders’ fees or commissions in connection with the transactions contemplated by this Agreement asserted by any Person on the
basis of any agreement, statement or representation alleged to have been made by such Purchaser. 
 4.7 Foreign Investors.
If the Purchaser is not a United States Person (as defined by Section 7701(a)(30) of the Code), such Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any
invitation to subscribe for the Shares or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, (ii) any foreign exchange restrictions applicable to such purchase,
(iii) any government or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Shares. The Company’s
offer and sale and Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of Purchaser’s jurisdiction. 

4.8 Transfer Restrictions. Each Purchaser acknowledges and agrees that the Shares and, if issued, the Conversion Shares are subject to
restrictions on transfer as set forth in the Investor Rights Agreement. 
 5. CONDITIONS PRECEDENT OF THE PURCHASERS. Unless
otherwise indicated below, the obligation of the Purchasers to purchase Shares at the First Tranche Closing and any subsequent Second Tranche Closing is subject to the fulfillment, or the waiver by the Purchasers, of each of the following conditions

7.2 Reservation of Common Stock. The Company shall reserve and maintain a sufficient number of shares of Common Stock for issuance upon

7.4 Compliance with Laws. The Company shall comply, and cause each of its subsidiaries, if any, to comply, with all applicable laws, rules,

MISCELLANEOUS. 
 8.1 Successors and Assigns. This Agreement, and the rights and obligations of each Purchaser hereunder, may
be assigned by the Purchaser to any Person to which Shares are transferred by the Purchaser, and such transferee shall be deemed to be the “Purchaser” for purposes of this Agreement; provided that the transferee provides written notice of
such assignment to the Company and agrees in writing to be bound by and comply with all provisions of this Agreement. 
 8.2
Survival of Representations and Warranties. All covenants, representations and warranties contained herein shall survive the execution and delivery of this Agreement and the closing of the transactions contemplated hereby and shall in no

 8.3
Indemnification.  
 (a) The Company agrees to indemnify and hold harmless each Purchaser and its respective
directors, officers, trustees, members, managers, employees and agents from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and other expenses
incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) to which such Person (as defined below) may
become subject as a result of any breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under this Agreement and the Ancillary Agreements, and will reimburse any such Person for all such
amounts as they are incurred by such Person. 
 (b) Any Person entitled to indemnification hereunder shall (i) give prompt
notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party;
provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person
unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such Person or (c) in the
reasonable judgment of any such Person, based upon written advice of its counsel, a conflict of interest exists between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party
in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person); and provided,
further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give


  
 -16-









 
notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any
proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to
entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

 8.4 Expenses. On the First Tranche Closing Date, the Company shall reimburse Aisling Capital III, LP for its reasonable fees
and expenses (including its reasonable legal fees and expenses) up to $65,000. Except as set forth above, the Company and each of the Purchasers shall be responsible for their own fees and expenses in connection with the transactions contemplated
hereby. 
 8.5 Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively

receipt.

07059, Attention: Chief Executive Officer, or at such other address or addresses as may have been furnished by ten days advance written notice in writing by the Company to such Purchaser. 

If such notice is addressed to any Purchaser, at the address set forth in Attachment 1, or at such other address or
addresses as may have been furnished by ten (10) days advance written notice to the Company in writing by such Purchaser.

Except as otherwise expressly set forth in this Agreement, any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of 100% of the Shares purchased pursuant to this Agreement (treated as if converted and including any Conversion Shares into which the then outstanding Shares have been

Headings; Schedules. The section headings are for the convenience of the parties only and in no way alter, modify, amend, limit or restrict the contractual obligations of the parties. Any matter disclosed as to any section of this Agreement

default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of
any holder of any breach or 

  
 -18-









 
default under this Agreement, or any waiver on the part of any holder of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically
