Ladies and Gentlemen: 
 Zosano Pharma
Corporation, a Delaware corporation (the “Company”), confirms its agreement (this “Agreement”) with Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC (each, an
“Agent,” and together, the “Agents”), as follows: 
 1.    Issuance
and Sale of Shares. The Company agrees that, from time to time during the term of this Agreement, on the terms and subject to the conditions set forth herein, it may issue and sell through the Agents, shares of common stock (the
“Placement Shares”) of the Company, par value $0.0001 per share (the “Common Stock”); provided, however, that in no event shall the Company issue or sell through the Agents such number or
dollar amount of Placement Shares that would (a) exceed the number or dollar amount of shares of Common Stock registered on the effective Registration Statement (defined below) pursuant to which the offering is being made, (b) exceed the
number of authorized but unissued shares of Common Stock (less shares of Common Stock issuable upon exercise, conversion or exchange of any outstanding securities of the Company or otherwise reserved from the Company’s authorized capital
stock), (c) exceed the number or dollar amount of shares of Common Stock permitted to be sold under Form S-3 (including General Instruction I.B.6 thereof, if applicable) or (d) exceed the number or dollar
amount of shares of Common Stock for which the Company has filed a Prospectus Supplement (defined below) (the lesser of (a), (b), (c) and (d), the “Maximum Amount”). Notwithstanding anything to the contrary contained herein,
the parties hereto agree that compliance with the limitations set forth in this Section 1 on the amount of Placement Shares issued and sold under this Agreement shall be the sole responsibility of the Company and that the
Agents shall have no obligation in connection with such compliance. The offer and sale of Placement Shares through the Agents will be effected pursuant to the Registration Statement (as defined below) filed by the Company and declared effective by
the Securities and Exchange Commission (the “Commission”) on April 16, 2020, although nothing in this Agreement shall be construed as requiring the Company to use the Registration Statement to issue Common Stock. 












 The Company has filed, in accordance with the provisions of the Securities Act of 1933, as
amended (the “Securities Act”) and the rules and regulations thereunder (the “Securities Act Regulations”), with the Commission a registration statement on Form
S-3 (File No. 333-237187), including a base prospectus, relating to certain securities, including the Placement Shares to be issued from time to time by the
Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and
regulations thereunder. The Company has prepared a prospectus or a prospectus supplement to the base prospectus included as part of the registration statement, which prospectus or prospectus supplement relates to the Placement Shares to be issued
from time to time by the Company (the “Prospectus Supplement”). The Company will furnish to the Agents, for use by the Agents, copies of the prospectus included as part of such registration statement, as supplemented, by the
Prospectus Supplement, relating to the Placement Shares to be issued from time to time by the Company. The Company may file one or more additional registration statements from time to time that will contain a base prospectus and related prospectus
or prospectus supplement, if applicable (which shall be a Prospectus Supplement), with respect to the Placement Shares. Except where the context otherwise requires, such registration statement(s), including all documents filed as part thereof or
incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act Regulations or deemed to be a part of such
registration statement pursuant to Rule 430B of the Securities Act Regulations, is herein called the “Registration Statement.” The base prospectus or base prospectuses, including all documents incorporated therein by
reference, included in the Registration Statement, as it may be supplemented, if necessary, by the Prospectus Supplement, in the form in which such prospectus or prospectuses and/or Prospectus Supplement have most recently been filed by the Company
with the Commission pursuant to Rule 424(b) under the Securities Act Regulations, together with the then issued Issuer Free Writing Prospectus(es) (as defined below), is herein called the “Prospectus.” 

Any reference herein to the Registration Statement, any Prospectus Supplement, Prospectus or any Issuer Free Writing Prospectus shall be
deemed to refer to and include the documents, if any, incorporated by reference therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such
Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus
shall be deemed to refer to and include the filing of any document under the Exchange Act on or after the most-recent effective date of the Registration Statement, or the date of the Prospectus Supplement, Prospectus or such Issuer Free Writing
Prospectus, as the case may be, and incorporated therein by reference. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall be deemed to include the most recent
copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval system, or if applicable, the Interactive Data Electronic Application system when used by the Commission (collectively, “EDGAR”).

 2.    Placements. Each time that the Company wishes to issue and
sell Placement Shares hereunder (each, a “Placement”), it will notify an Agent (such Agent, the “Designated Agent”) by email notice (or other method mutually agreed to by the parties) of the number of
Placement Shares to be issued, the time period during which sales are requested to be made, any limitation on the number of Placement Shares that may be sold in any one day and any minimum price below which sales may not be made (a
“Placement Notice”), the form of which is attached hereto as Schedule 1. The Placement Notice shall originate from any of the individuals from the Company set forth on Schedule 3 (with a copy to each of the
other individuals from the Company listed on such schedule), and shall be addressed to each of the individuals from the Designated Agent to whom the Placement Notice is delivered, as set forth on Schedule 3, as such Schedule 3 may be
amended from time to time. The Placement Notice shall be effective unless and until (i) the Designated Agent declines to accept the terms contained therein for any reason, in its sole discretion, (ii) the entire amount of the Placement
Shares thereunder have been sold, (iii) the Company suspends or terminates the Placement Notice or (iv) this Agreement has been terminated under the provisions of Section 12. The amount of any discount, commission
or other compensation to be paid by the Company to the Designated Agent in connection with the sale of the Placement Shares shall be calculated in accordance with the terms set forth in Schedule 2. It is expressly acknowledged and agreed that
neither the Company nor the Agents will have any obligation whatsoever with respect to a Placement or any Placement Shares unless and until the Company delivers a Placement Notice to the Designated Agent and the Designated Agent does not decline
such Placement Notice pursuant to the terms set forth above, and then only upon the terms specified therein and herein. In the event of a conflict between the terms of this Agreement and the terms of a Placement Notice, the terms of the Placement
Notice will control. 
 3.    Sale of Placement Shares by the Agents. Subject to the provisions of
Section 5(a), the Designated Agent that receives a Placement Notice, for the period specified in the Placement Notice, will use its commercially reasonable efforts consistent with its normal trading and sales practices and
applicable state and federal laws, rules and regulations and the rules of the Nasdaq Stock Market, to sell the Placement Shares up to the amount specified, and otherwise in accordance with the terms of such Placement Notice. The Designated Agent
will provide written confirmation to the Company no later than the opening of the Trading Day (as defined below) immediately following the Trading Day on which it has made sales of Placement Shares hereunder setting forth the number of Placement
Shares sold on such day, the compensation payable by the Company to the Designated Agent pursuant to Section 2 with respect to such sales, and the Net Proceeds (as defined below) payable to the Company, with an itemization
of the deductions made by the Designated Agent (as set forth in Section 5(b)) from the gross proceeds that it receives from such sales. Subject to the terms of the Placement Notice, the Designated Agent may sell Placement
Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act Regulations, including sales made directly on or through The Nasdaq Capital Market (the
“Exchange”) or any other existing trading market for the Common Stock, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices and/or any other method
permitted by law. “Trading Day” means any day on which Common Stock is traded on the Exchange. 

4.    Suspension of Sales. The Company or the Designated Agent may, upon notice to the other party in writing
(including by email correspondence to each of the individuals of the other party set forth on Schedule 3, if receipt of such correspondence is actually acknowledged by 

  
 3 













 
any of the individuals to whom the notice is sent, other than via auto-reply) or by telephone (confirmed immediately by verifiable facsimile transmission or email correspondence to each of the
individuals of the other party set forth on Schedule 3), suspend any sale of Placement Shares (a “Suspension”); provided, however, that such Suspension shall not affect or impair any party’s
obligations with respect to any Placement Shares sold hereunder prior to the receipt of such notice. While a Suspension is in effect any obligation under Sections 7(l), 7(m), and 7(n) with respect to the delivery of
certificates, opinions, or comfort letters to the Agents, shall be waived. Each of the parties agrees that no such notice under this Section 4 shall be effective against any other party unless it is made to one of the
individuals named on Schedule 3 hereto, as such Schedule may be amended from time to time. 
 5.    Sale and
Delivery to the Agent; Settlement. 
 (a)    Sale of Placement Shares. On the basis of the
representations and warranties herein contained and subject to the terms and conditions herein set forth, upon the Designated Agent’s acceptance of the terms of a Placement Notice, and unless the sale of the Placement Shares described therein
has been declined, suspended, or otherwise terminated in accordance with the terms of this Agreement, the Designated Agent, for the period specified in the Placement Notice, will use its commercially reasonable efforts consistent with its normal
trading and sales practices and applicable law and regulations to sell such Placement Shares up to the amount specified, and otherwise in accordance with the terms of such Placement Notice. The Company acknowledges and agrees that (i) there can
be no assurance that the Designated Agent will be successful in selling Placement Shares, (ii) the Designated Agent will incur no liability or obligation to the Company or any other person or entity if it does not sell Placement Shares for any
reason other than a failure by the Designated Agent to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Placement Shares as required under this Agreement
and (iii) the Designated Agent shall be under no obligation to purchase Placement Shares on a principal basis pursuant to this Agreement, except as otherwise agreed by the Designated Agent and the Company. 

(b)    Settlement of Placement Shares. Unless otherwise specified in the applicable Placement Notice,
settlement for sales of Placement Shares will occur on the second (2nd) Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made (each,
a “Settlement Date”). The Designated Agent shall notify the Company of each sale of Placement Shares no later than the opening of the Trading Day immediately following the Trading Day on which it has made sales of Placement
Shares hereunder. The amount of proceeds to be delivered to the Company on a Settlement Date against receipt of the Placement Shares sold (the “Net Proceeds”) will be equal to the aggregate sales price received by the
Designated Agent, after deduction for (i) the Designated Agent’s commission, discount or other compensation for such sales payable by the Company pursuant to Section 2 hereof, and (ii) any transaction fees
imposed by any Governmental Authority (as defined below) in respect of such sales. 
 (c)     Delivery of
Placement Shares. On or before each Settlement Date, the Company will, or will cause its transfer agent to, electronically transfer the Placement Shares being sold by crediting the account of the Designated Agent or its designee’s account
(provided the Designated Agent shall have given the Company written notice of such designee at least one Trading Day prior to the Settlement Date) at The Depository Trust Company through its Deposit 


  
 4 













 
and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto which in all cases shall be freely tradable, transferable, registered
shares in good deliverable form. On each Settlement Date, the Designated Agent will deliver the related Net Proceeds in same day funds to an account designated by the Company on, or prior to, the Settlement Date. The Company agrees that if the
Company, or its transfer agent (if applicable), defaults in its obligation to deliver Placement Shares on a Settlement Date, the Company agrees that in addition to and in no way limiting the rights and obligations set forth in
Section 10(a) hereto, it will (i) hold the Designated Agent harmless against any loss, claim, damage, or expense (including reasonable and documented legal fees and expenses), as incurred, arising out of or in
connection with such default by the Company or its transfer agent (if applicable) and (ii) pay to the Designated Agent any commission, discount, or other compensation to which it would otherwise have been entitled absent such default. 

(d)    Denominations; Registration. Certificates for the Placement Shares, if any, shall be in such
denominations and registered in such names as the Agents may request in writing at least one full Business Day (as defined below) before the Settlement Date. The certificates for the Placement Shares, if any, will be made available by the Company
for examination and packaging by the Agents in The City of New York not later than noon (New York time) on the Business Day prior to the Settlement Date. 

(e)    Limitations on Offering Size. Under no circumstances shall the Company cause or request the offer or
sale of any Placement Shares if, after giving effect to the sale of such Placement Shares, the aggregate gross sales proceeds of Placement Shares sold pursuant to this Agreement would exceed the lesser of (A) together with all sales of
Placement Shares under this Agreement, the Maximum Amount and (B) the amount authorized from time to time to be issued and sold under this Agreement by the Company’s board of directors, a duly authorized committee thereof or a duly
authorized executive committee, and notified to the Designated Agent in writing. Under no circumstances shall the Company cause or request the offer or sale of any Placement Shares pursuant to this Agreement at a price lower than the minimum price
authorized from time to time by the Company’s board of directors, a duly authorized committee thereof or a duly authorized executive committee. Further, under no circumstances shall the Company cause or permit the aggregate offering amount of
Placement Shares sold pursuant to this Agreement to exceed the Maximum Amount. 
 (f)    Sales Through Agents.
With respect to the offering and sale of Placement Shares pursuant to this Agreement, the Company agrees that any offer to sell Placement Shares, any solicitation of an offer to buy Placement Shares, and any sales of Placement Shares shall only be
effected by or through one single Agent as the Designated Agent on any single given Trading Day, and in no event shall the Company request that more than one Agent offer or sell Placement Shares pursuant to this Agreement on the same Trading Day.

 6.    Representations and Warranties of the Company. The Company represents and warrants to, and agrees with
the Agents that as of the date of this Agreement and as of each Applicable Time (as defined below): 

(a)    Registration Statement and Prospectus. The Company and the transactions contemplated by this
Agreement meet the requirements for and comply with the applicable conditions set forth in Form S-3 (including General Instructions I.A and I.B) under the Securities


  
 5 













 
Act. The Registration Statement has been filed with the Commission and has been declared effective by the Commission under the Securities Act. The Prospectus Supplement will name the Agents as
agents in the section titled “Plan of Distribution.” The Company has not received, and has no notice of, any order of the Commission preventing or suspending the use of the Registration Statement, or threatening or instituting proceedings
for that purpose. The Registration Statement and the offer and sale of Placement Shares as contemplated hereby meet the requirements of Rule 415 under the Securities Act and comply in all material respects with said Rule. Any statutes,
regulations, contracts or other documents that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement have been so described or filed. Copies of the Registration
Statement, the Prospectus, and any such amendments or supplements and all documents incorporated by reference therein that were filed with the Commission on or prior to the date of this Agreement have been delivered, or are available through EDGAR,
to the Agents and their counsel. The Company has not distributed and, prior to the later to occur of each Settlement Date and completion of the distribution of the Placement Shares, will not distribute any offering material in connection with the
offering or sale of the Placement Shares other than the Registration Statement and the Prospectus and any Issuer Free Writing Prospectus (as defined below) to which the Agents have consented. The Common Stock is registered pursuant to
Section 12(b) of the Exchange Act and is currently listed on the Exchange under the trading symbol “ZSAN.” The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock
under the Exchange Act, delisting the Common Stock from the Exchange, nor has the Company received any notification that the Commission or the Exchange is contemplating terminating such registration or listing. Other than as disclosed in the
Registration Statement or the Prospectus, to the Company’s knowledge, it is in compliance with all applicable listing requirements of the Exchange. 

(b)    No Misstatement or Omission. The Registration Statement, when it became or becomes effective, and the
Prospectus, and any amendment or supplement thereto, on the date of such Prospectus or amendment or supplement, conformed and will conform in all material respects with the requirements of the Securities Act. At each Settlement Date, the
Registration Statement and the Prospectus, as of such date, will conform in all material respects with the requirements of the Securities Act. The Registration Statement, when it became or becomes effective, did not, and will not, contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus and any amendment and supplement thereto, on the date thereof and at each
Applicable Time (defined below), did not or will not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.
The documents incorporated by reference in the Prospectus or any Prospectus Supplement did not, and any further documents filed and incorporated by reference therein will not, when filed with the Commission, contain an untrue statement of a material
fact or omit to state a material fact required to be stated in such document or necessary to make the statements in such document, in light of the circumstances under which they were made, not misleading. The foregoing shall not apply to statements
in, or omissions from, any such document made in reliance upon, and in conformity with, information furnished to the Company by either Agent specifically for use in the preparation thereof. 

(c)    Free Writing Prospectuses. As of the determination date referenced in Rule 164(h) under the
Securities Act, the Company was not, is not or will not be (as applicable) an 

  
 6 













 
“ineligible issuer” in connection with the offering of the Placement Shares pursuant to Rules 164, 405 and 433 under the Securities Act. Each free writing prospectus that the Company is
required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each free writing prospectus that the Company has filed, or is required to
file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act,
including timely filing with the Commission or retention where required and legending, and each such free writing prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Placement
Shares did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus and not superseded or modified. Except for the free writing
prospectuses, if any, identified in Schedule B, the Company has not prepared, used or referred to, and will not, without the Agents’ prior written consent, prepare, use or refer to, any free writing prospectus. 

(d)    Market Capitalization. At the time the Registration Statement was originally declared effective, and
at the time the Company’s most recent Annual Report on Form 10-K was filed with the Commission, the Company met the then applicable requirements for the use of Form
S-3 under the Securities Act, including, if applicable, General Instruction I.B.6 of Form S-3. The aggregate market value of the outstanding voting and non-voting common equity (as defined in Securities Act Rule 405) of the Company held by persons other than affiliates of the Company (pursuant to Securities Act Rule 144, those that directly, or indirectly through
one or more intermediaries, control, or are controlled by, or are under common control with, the Company) (the “Non-Affiliate Shares”), was equal to or greater than $75
million (calculated by multiplying (x) the highest price at which the common equity of the Company closed on the Exchange within 60 days of March 11, 2021 times (y) the number of
Non-Affiliate Shares). The Company is not a shell company (as defined in Rule 405 under the Securities Act) and has not been a shell company for at least 12 calendar months previously and if it has been a
shell company at any time previously, has filed current Form 10 information (as defined in Instruction I.B.6 of Form S-3) with the Commission at least 12 calendar months previously reflecting its status as an
entity that is not a shell company. 
 (e)    Financial Information. The financial statements of the
Company included or incorporated by reference in the Registration Statement, the Prospectus and the Issuer Free Writing Prospectuses, if any, together with the related notes and schedules, present fairly, in all material respects, the financial
position of the Company as of the dates indicated and the results of operations, cash flows and changes in stockholders’ equity of the Company for the periods specified and have been prepared in compliance with the requirements of the
Securities Act and Exchange Act and in conformity with GAAP (as defined below) applied on a consistent basis during the periods involved; there are no financial statements (historical or pro forma) that are required to be included or incorporated by
reference in the Registration Statement, the Prospectus and the Issuer Free Writing Prospectuses, if any, that are not included or incorporated by reference as required; the Company does not have any material liabilities or obligations, direct or
contingent (including any off-balance sheet obligations), not described in the Registration Statement (excluding the exhibits thereto) and the Prospectus; and all disclosures contained or incorporated by
reference in the Registration Statement, the Prospectus and the Issuer Free Writing 

  
 7 













 
Prospectuses, if any, regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply
with Regulation G of the Exchange Act and Item 10 of Regulation S-K under the Securities Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language included or incorporated
by reference in the Registration Statement and the Prospectus fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto. 

(f)    Conformity with EDGAR Filing. The Prospectus delivered to the Agents for use in connection with the
sale of the Placement Shares pursuant to this Agreement will be identical to the versions of the Prospectus created to be transmitted to the Commission for filing via EDGAR, except to the extent permitted by Regulation
S-T. 
 (g)    Organization. The Company is duly organized,
validly existing as a corporation and in good standing under the Laws (as defined below) of its jurisdiction of organization. The Company is duly licensed or qualified as a foreign corporation for transaction of business and in good standing under
the Laws of each other jurisdiction in which its ownership or lease of property or the conduct of its business requires such license or qualification, and has all corporate power and authority necessary to own or hold its properties and to conduct
its business as described in the Registration Statement and the Prospectus, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect
on or affecting the assets, business, operations, earnings, properties, condition (financial or otherwise), prospects, stockholders’ equity or results of operations of the Company, or prevent or materially interfere with the consummation of the
transactions contemplated hereby (a “Material Adverse Effect”). 

(h)    Subsidiaries. The Company, directly or indirectly, owns no capital stock or other equity or ownership
or proprietary interest in any corporation, partnership, association, trust or other entity. 
 (i)    No
Violation or Default. The Company is not (i) in violation of its charter or by-laws or similar organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of
time or both, would constitute such a default, in the due performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company is a
party or by which the Company is bound or to which any of the property or assets of the Company is subject; or (iii) in violation of any Law of any Governmental Authority, except, in the case of each of clauses (ii) and (iii) above, for
any such violation or default that would not, individually or in the aggregate, have a Material Adverse Effect. To the Company’s knowledge, no other party under any material contract or other agreement to which it is a party is in default in
any respect thereunder where such default would have a Material Adverse Effect. 
 (j)    No Material Adverse
Effect. Subsequent to the respective dates as of which information is given in the Registration Statement the Prospectus and the free writing prospectuses, if any, identified on Exhibit B hereto (including any document deemed incorporated
by reference therein), there has not been (i) any Material Adverse Effect or the occurrence of any development that the Company reasonably expects will result in a Material Adverse Effect, (ii) any transaction which is material to the
Company, (iii) any obligation or liability, direct or contingent (including any off-balance sheet obligations), incurred by the Company, which is material to the Company,


  
 8 













 
(iv) any material change in the capital stock or outstanding long-term indebtedness of the Company or (v) any dividend or distribution of any kind declared, paid or made on the capital stock
of the Company, other than in each case above in the ordinary course of business or as otherwise disclosed in the Registration Statement or Prospectus (including any document deemed incorporated by reference therein). 

(k)    Capitalization. The issued and outstanding shares of capital stock of the Company have been validly
issued, are fully paid and nonassessable and, other than as disclosed in the Registration Statement or the Prospectus, are not subject to any preemptive rights, rights of first refusal or similar rights. The Company has an authorized, issued and
outstanding capitalization as set forth in the Registration Statement and the Prospectus as of the dates referred to therein (other than the grant of additional options or restricted stock units under the Company’s existing stock option plans,
or changes in the number of outstanding shares of Common Stock of the Company due to the issuance of shares upon the exercise or conversion of securities exercisable for, or convertible into, Common Stock outstanding on the date hereof or the
issuance of shares of Common Stock upon the vesting and settlement of restricted stock units outstanding on the date hereof) and such authorized capital stock conforms in all material respects to the description thereof set forth in the Registration
Statement and the Prospectus. The description of the securities of the Company in the Registration Statement and the Prospectus is complete and accurate in all material respects. Except as disclosed in the Registration Statement and the Prospectus,
the Company does not have outstanding any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to issue or sell, any shares of
capital stock or other securities. 
 (l)    Authorization; Enforceability. The Company has full legal
right, power and authority to enter into this Agreement and perform the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Company and is a legal, valid and binding agreement of the Company
enforceable in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except to the extent that enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or
similar Laws affecting creditors’ rights generally and by general equitable principles. 

(m)    Authorization of the Placement Shares. The Placement Shares have been duly authorized for issuance
and sale pursuant to this Agreement and, when issued and delivered by the Company against payment therefor pursuant to this Agreement, will be duly and validly issued, fully paid and nonassessable, free and clear of any pledge, lien, encumbrance,
security interest or other claim, including any statutory or contractual preemptive rights, resale rights, rights of first refusal or other similar rights, and will be registered pursuant to Section 12 of the Exchange Act. The Placement Shares,
when issued, will conform in all material respects to the description thereof set forth in or incorporated into the Registration Statement and the Prospectus. 

(n)    No Consents Required. No consent, approval, authorization, order, registration or qualification of or
with any Governmental Authority is required for the execution, delivery and performance by the Company of this Agreement, the issuance and sale by the Company of the Placement Shares, except for such consents, approvals, authorizations, orders and
registrations or qualifications as may be required under applicable state securities Laws or Laws of the Financial Industry Regulatory Authority Inc. (“FINRA”) or the Exchange in connection with the sale of the Placement
Shares.

term is defined in Rule 1-02 of Regulation S-X promulgated under the Securities Act (each, a “Person”), has the right, contractual or otherwise,

(p)    Independent Public Accounting Firm. To the Company’s knowledge, Deloitte & Touche LLP

10-K filed with the Commission and incorporated by reference into the Registration Statement and the Prospectus, are and, during the periods covered by their report, were an independent registered public

pharmaceutical products) necessary for the ownership or lease of its properties or to conduct its business as described in the Registration Statement and the Prospectus (collectively, “Permits”), except for such Permits the
failure of which to possess, obtain or make the same would not reasonably be expected to have a Material Adverse Effect; the Company is in compliance with the terms and conditions of all such Permits, except where the failure to be in compliance
would not reasonably be expected to have a Material Adverse Effect; all of the Permits are valid and in full force and effect, except where any invalidity, individually or in the aggregate, would not reasonably be expected to have a Material Adverse
Effect; and the Company has not received any written notice relating to the limitation, revocation, cancellation, suspension, modification or non-renewal of any such Permit which, singly or in the aggregate,
if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect, or has any reason to believe that any such license, certificate, permit or authorization will not be renewed in the
ordinary course, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(t)    Regulatory Filings. The Company has not failed to file with the applicable Governmental Authority
(including the FDA, or any foreign, federal, state, provincial or local Governmental Authority performing functions similar to those performed by the FDA) any required filing, declaration, listing, registration, report or submission, except for such
failures that, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect; all such filings, declarations, listings, registrations, reports or submissions were in compliance with applicable Laws when filed
and no deficiencies have been asserted by any applicable regulatory authority with respect to any such filings, declarations, listings, registrations, reports or submissions, except for any deficiencies that, individually or in the aggregate, would

FDA and other federal, state, local and foreign Governmental Authority exercising comparable authority, except where the failure to be in compliance would not reasonably be expected to have a Material Adverse Effect.

and domestic patents, patent applications, trade and service marks, trade and service mark registrations, trade names, copyrights, licenses, inventions, trade secrets, technology, Internet domain names,
know-how and other intellectual property (collectively, the “Intellectual Property”), necessary for the conduct of its business as now conducted except to the extent that the failure to
own, possess, license or otherwise hold adequate rights to use such Intellectual Property would not, individually or in the aggregate, have a Material Adverse Effect. (i) Except as disclosed in the Registration Statement and the Prospectus,

action, suit, proceeding or claim by others challenging the validity or scope of any such Intellectual Property; (v) there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others that the

Company; and (vii) the Company has complied with the terms of each agreement pursuant to which Intellectual Property has been licensed to the Company, and all such agreements are in full force and effect, except, in the case of any of clauses
(i)-(vii) above, for any such infringement by third parties or any such pending or threatened suit, action, proceeding or claim as would not, individually or in the aggregate, result in a Material Adverse Effect. 

(v)    Clinical Studies. The preclinical studies and tests and clinical trials described in the Registration
Statement and the Prospectus were, and, if still pending, are being conducted in all material respects in accordance with all applicable rules, regulations and policies of the FDA and comparable regulatory agencies outside of the United States to
which such studies, tests or trials are subject; the descriptions of such studies, tests and trials, and the results thereof, contained in the Registration Statement and the Prospectus are accurate in all material respects; the Company is not aware
of any tests, studies or trials not described in the Registration Statement and the Prospectus, the results of which reasonably call into question in any material respect the results of the tests, studies and trials described in the Registration
Statement and the Prospectus; and the Company has not received any written notice or correspondence from the FDA or any foreign, state or local Governmental Authority exercising comparable authority or any institutional review board or comparable
authority requiring the termination, suspension or clinical hold of any tests, studies or trials. 
 (w)    No
Material Defaults. The Company has not defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or in the aggregate, would have a Material Adverse Effect. The
Company has not filed a report pursuant to Sections 13(a) or 15(d) of the Exchange Act since the filing of its last Annual Report on Form 10-K, indicating that it (i) has failed to pay any dividend or
sinking fund installment on preferred stock or (ii) has defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or in the aggregate, would have a Material
Adverse Effect. 
 (x)    Certain Market Activities. The Company has not taken, directly or indirectly,
any action designed to or that might cause or result in stabilization or manipulation of the price of the Shares or of any “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation
M”)) with respect to the Common Stock, whether to facilitate the sale or resale of the Placement Shares or otherwise, and has taken no action which would directly or indirectly violate Regulation M. 

(y)    Broker/Dealer Relationships. The Company (i) is not required to register as a “broker”
or “dealer” in accordance with the provisions of the Exchange Act and (ii) does not, directly or indirectly through one or more intermediaries, control, and is not, a “person associated with a member” or “associated

 12 













 (z)    No Reliance. The Company has not relied upon the
Agents or legal counsel for the Agents for any legal, tax or accounting advice in connection with the offering and sale of the Placement Shares. 

(aa)    Taxes. The Company has filed all federal, state, local and foreign tax returns which have been
required to be filed and paid all taxes shown thereon through the date hereof, to the extent that such taxes have become due and are not being contested in good faith, except where the failure to so file or pay would not have a Material Adverse
Effect. Except as otherwise disclosed in or contemplated by the Registration Statement and the Prospectus, no tax deficiency has been determined adversely to the Company which has had, or would have, individually or in the aggregate, a Material
Adverse Effect. The Company has no knowledge of any federal, state or other governmental tax deficiency, penalty or assessment that has been, or would reasonably be expected to be, asserted or threatened against it which would have a Material
Adverse Effect. 
 (bb)    Title to Real and Personal Property. The Company does not own any real
property. Except as set forth in the Registration Statement and the Prospectus, the Company has good and valid title to all personal property described in the Registration Statement or the Prospectus as being owned by it that is material to the
business of the Company, in each case free and clear of all liens, encumbrances and claims, except those matters that (i) do not materially interfere with the use made and proposed to be made of such property by the Company or (ii) would
not, individually or in the aggregate, have a Material Adverse Effect. Any real or personal property described in the Registration Statement or the Prospectus as being leased by the Company is held by it under valid, existing and enforceable leases,
except those that (A) do not materially interfere with the use made or proposed to be made of such property by the Company or (B) would not, individually or in the aggregate, have a Material Adverse Effect. To the Company’s knowledge,
each of the properties of the Company complies with all applicable Laws (including building and zoning Laws and Laws relating to access to such properties), except if and to the extent disclosed in the Registration Statement or the Prospectus or
except for such failures to comply that would not, individually or in the aggregate, reasonably be expected to interfere in any material respect with the use made and proposed to be made of such property by the Company or otherwise have a Material
Adverse Effect. The Company has not received from any Governmental Authorities any notice of any condemnation of, or zoning change affecting, the properties of the Company, and the Company knows of no such condemnation or zoning change which is
threatened, except for such that would not reasonably be expected to interfere in any material respect with the use made and proposed to be made of such property by the Company or otherwise have a Material Adverse Effect, individually or in the
aggregate. 
 (cc)    Environmental Laws. The Company (i) is in compliance with any and all
applicable federal, state, local and foreign Laws relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (collectively, “Environmental
Laws”); (ii) has received and is in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct its business as described in the Registration Statement or the Prospectus;
and (iii) has not received 

  
 13 













 
notice of any actual or potential liability for the investigation or remediation of any disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants, except, in the
case of any of clauses (i), (ii) or (iii) above, for any such failure to comply or failure to receive required permits, licenses, other approvals or liability as would not, individually or in the aggregate, have a Material Adverse Effect. 

(dd)    Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the
Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company, in the course of which it identifies and evaluates associated costs and liabilities (including any capital or operating
expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities
to third parties). No facts or circumstances have come to the Company’s attention in connection with such reviews that would, individually or in the aggregate, have a Material Adverse Effect. 

(ee)    Disclosure Controls. The Company maintains systems of internal accounting controls sufficient to
provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting is effective and the Company is not
aware of any material weaknesses in its internal control over financial reporting (other than as set forth in the Registration Statement or Prospectus). Since the date of the latest audited financial statements of the Company included in the
Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting (other than
as set forth in the Registration Statement or Prospectus). The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and
15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company is made known to the certifying officers by others within those
entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared.
The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the last day of the period covered by the Form 10-K for the fiscal year
most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the fiscal year most recently ended the conclusions of the certifying officers
about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date and the disclosure controls and procedures are effective as of the Evaluation Date. Since the Evaluation Date, there have been no
significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that could
materially affect the Company’s internal controls. 
 (ff)    Sarbanes-Oxley. There is and has been
no failure on the part of the Company or any of the Company’s directors or officers, in their capacities as such, to comply in 

  
 14 













 
all material respects with any applicable provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder. Each of the principal executive officer and the principal
financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company as applicable) has made all certifications required by Sections 302 and 906 of the Sarbanes-Oxley
Act with respect to all reports, schedules, forms, statements and other documents required to be filed by it or furnished by it to the Commission. For purposes of the preceding sentence, “principal executive officer” and “principal
financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act. 

(gg)    Brokers. The Company has not incurred any liability for any finder’s fees, brokerage
commissions or similar payments in connection with the transactions herein contemplated, except as may otherwise exist with respect to or pursuant to this Agreement. 

(hh)    Labor Disputes. No labor disturbance by or dispute with employees of the Company exists or, to the
knowledge of the Company, is threatened which would have a Material Adverse Effect. 
 (ii)    Investment
Company Act. The Company is not, and will not be, either after receipt of payment for the Placement Shares or after the application of the proceeds therefrom as described under “Use of Proceeds” in the Registration Statement or the
Prospectus, required to register as an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940 (the “Investment
Company Act”). 
 (jj)    Operations. The operations of the Company are and have been
conducted at all times in compliance with applicable financial record keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, the money laundering Laws of all jurisdictions to which the Company is subject,
the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any Governmental Authority (collectively, the “Money Laundering Laws”); and no action, suit
or proceeding by or before any Governmental Authority involving the Company with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened. 

(kk)    Off-Balance Sheet Arrangements. There are no transactions,
arrangements and other relationships between and/or among the Company, and/or any of its affiliates and any unconsolidated entity, including any structural finance, special purpose or limited purpose entity (each, an “Off-Balance Sheet Transaction”) that would affect materially the Company’s liquidity or the availability of or requirements for its capital resources, including those
Off-Balance Sheet Transactions described in the Commission’s Statement about Management’s Discussion and Analysis of Financial Conditions and Results of Operations (Release Nos. 33-8056; 34-45321; FR-61), required to be described in the Prospectus which have not been described as required. 

(ll)    ERISA. To the knowledge of the Company, each material employee benefit plan, within the meaning of
Section 3(3) of the Employee Retirement Income Security Act of 1974 (“ERISA”), that is maintained, administered or contributed to by the Company or any of its affiliates for employees or former employees of the Company
has been maintained in material compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including ERISA and the Internal Revenue Code of 1986 (the “Code”); no prohibited


  
 15 













 
transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred which would result in a material liability to the Company with respect to any such plan
excluding transactions effected pursuant to a statutory or administrative exemption; and for each such plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no “accumulated funding
deficiency” as defined in Section 412 of the Code has been incurred, whether or not waived, and the fair market value of the assets of each such plan (excluding for these purposes accrued but unpaid contributions) exceeds the present value
of all benefits accrued under such plan determined using reasonable actuarial assumptions. 

(mm)    Forward-Looking Statements. Each financial or operational projection or other “forward-looking
statement” (as defined by Section 27A of the Securities Act or Section 21E of the Exchange Act) contained in the Registration Statement or the Prospectus (i) was so included by the Company in good faith and with reasonable basis
after due consideration by the Company of the underlying assumptions, estimates and other applicable facts and circumstances and (ii) is accompanied by meaningful cautionary statements identifying those factors that could cause actual results
to differ materially from those in such forward-looking statement. 

(nn)    Margin Rules. Neither the issuance, sale and delivery of the Placement Shares nor the application of
the proceeds thereof by the Company as described in the Registration Statement and the Prospectus will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors. 

(oo)    Agent Purchases. The Company acknowledges and agrees that Agents have informed the Company that the
Agents may, to the extent permitted under the Securities Act and the Exchange Act, purchase and sell Common Stock for each Agent’s own account while this Agreement is in effect, provided, that (i) no such purchase or sales shall
take place while a Placement Notice is in effect (except to the extent the Agents may engage in sales of Placement Shares purchased or deemed purchased from the Company as a “riskless principal” or in a similar capacity) and (ii) the
Company shall not be deemed to have authorized or consented to any such purchases or sales by the Agents. 

(pp)    Reserved. 

(qq)    Insurance. The Company carries, or is covered by, insurance in such amounts and covering such risks
as the Company reasonably believes are adequate for the conduct of its properties and as is customary for companies engaged in similar businesses in similar industries. 

(rr)    No Improper Practices. (i) Neither the Company nor any director or officer of the Company, nor,
to the Company’s knowledge, any employee, agent, affiliate or other person acting on behalf of the Company has, in the past five years, made any unlawful contributions to any candidate for any political office (or failed fully to disclose any
contribution in violation of applicable Law) or made any contribution or other payment to any official of, or candidate for, any federal, state, municipal, or foreign office or other person charged with similar public or quasi-public duty in
violation of any applicable Law or of the character required to be disclosed in the Prospectus; (ii) no relationship, direct or indirect, exists between or among the Company or any affiliate of the Company, on the one hand, and the directors,
officers and stockholders of the Company, on the other hand, that is required by the Securities Act to be described in the 

  
 16 













 
Registration Statement and the Prospectus that is not so described; (iii) no relationship, direct or indirect, exists between or among the Company or any affiliate of the Company, on the one

customer’s or supplier’s level or type of business with the Company or (B) a trade journalist or publication to write or publish favorable information about the Company or any of its products or services, and, (vi) neither the
Company nor any director or officer of the Company, nor, to the Company’s knowledge, any employee, agent, affiliate or other person acting on behalf of the Company has (A) violated or is in violation of any applicable provision of the U.S.

of value, directly or indirectly, to any person for the purpose of obtaining or retaining business, influencing any act or decision of the recipient or securing any improper advantage, or (C) made any payment of funds of the Company or received
or retained any funds in violation of any Anti-Corruption Laws. 
 (ss)    No Conflicts. Neither the
execution of this Agreement, nor the issuance, offering or sale of the Placement Shares, nor the consummation of any of the transactions contemplated herein and therein, nor the compliance by the Company with the terms and provisions hereof and
thereof will conflict with, or will result in a breach of, any of the terms and provisions of, or has constituted or will constitute a default under, or has resulted in or will result in the creation or imposition of any lien, charge or encumbrance
upon any property or assets of the Company pursuant to the terms of any contract or other agreement to which the Company may be bound or to which any of the property or assets of the Company is subject, except (i) such conflicts, breaches or
defaults as may have been waived and (ii) such conflicts, breaches and defaults that would not have a Material Adverse Effect; nor will such action result (x) in any violation of the provisions of the organizational or governing documents
of the Company, or (y) in any material violation of the provisions of any statute or any order, rule or regulation applicable to the Company or of any Governmental Authority having jurisdiction over the Company. 

(tt)    Sanctions. 

(i)    The Company represents that, neither the Company (the “Entity”) nor any director or officer

Prospectus relating to any Placement Shares is required to be delivered by the Agents under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act or similar rule),
(i) the Company will notify the Agents promptly of the time when any subsequent amendment to the Registration Statement, other than documents incorporated by reference, has been filed with the Commission and/or has become effective or any

Company of any obligation or liability hereunder, or affect the Agents’ right to rely on the representations and warranties made by the Company in this Agreement and provided, further, that the only remedy the Agents shall have
with respect to the failure by the Company to obtain such consent shall be to cease making sales under this Agreement) and the Company will furnish to the Agents at the time of filing thereof a copy of any document that upon filing is deemed to be
incorporated by reference into the Registration Statement or Prospectus, except for those documents available via EDGAR; and (iv) the Company will cause each amendment or supplement to the Prospectus to be filed with the Commission as required
pursuant to the applicable paragraph of Rule 424(b) of the Securities Act or, in the case of any document to be incorporated therein by reference, to be filed with the Commission as required pursuant to the


  
 20 













 
Exchange Act, within the time period prescribed (the determination to file or not file any amendment or supplement with the Commission under this Section 7(a), based on
the Company’s reasonable opinion or reasonable objections, shall be made exclusively by the Company). 

(b)    Notice of Commission Stop Orders. The Company will advise the Agents, promptly after it receives notice or
obtains knowledge thereof, of the issuance or threatened issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Placement Shares for offering or sale in
any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and it will promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order
should be issued. The Company will advise the Agents promptly after it receives any request by the Commission for any amendments to the Registration Statement or any amendment or supplements to the Prospectus or any Issuer Free Writing Prospectus or
for additional information related to the offering of the Placement Shares or for additional information related to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus. 

(c)    Delivery of Prospectus; Subsequent Changes. During any period in which a Prospectus relating to the
Placement Shares is required to be delivered by the Agents under the Securities Act with respect to the offer and sale of the Placement Shares, (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the
Securities Act or similar rule), the Company will comply with all requirements imposed upon it by the Securities Act, as from time to time in force, and to file on or before their respective due dates all reports and any definitive proxy or
information statements required to be filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14, 15(d) or any other provision of or under the Exchange Act. If the Company has omitted any information from the Registration
Statement pursuant to Rule 430B under the Securities Act, it will use its best efforts to comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430B and to notify the Agents promptly of all such
filings. If during such period any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Securities Act, the Company will promptly notify the Agents to
suspend the offering of Placement Shares during such period and the Company will promptly amend or supplement the Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or effect such
compliance. 
 (d)    Listing of Placement Shares. Prior to the date of the first Placement Notice, the Company
will use its reasonable best efforts to cause the Placement Shares to be listed on the Exchange. 
 (e)    Delivery
of Registration Statement and Prospectus. The Company will furnish to the Agents and their counsel (at the expense of the Company) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein)
and all amendments and supplements to the Registration Statement or Prospectus that are filed with the Commission during any period in which a Prospectus relating to the Placement Shares is required to be delivered under the Securities Act
(including all documents filed with the Commission during 

  
 21 













 
such period that are deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities as the Agents may from time to time reasonably request
and, at the Agents’ request, will also furnish copies of the Prospectus to each exchange or market on which sales of the Placement Shares may be made; provided, however, that the Company shall not be required to furnish any
document (other than the Prospectus) to the Agents to the extent such document is available on EDGAR. 

(f)    Earning Statement. To the extent not available on EDGAR, the Company will make generally available to its
security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earning statement covering a 12-month period that satisfies the
provisions of Section 11(a) and Rule 158 of the Securities Act. 
 (g)    Use of Proceeds. The Company will
use the Net Proceeds as described in the Prospectus in the section entitled “Use of Proceeds.” 

(h)    Notice of Other Sales. Without the prior written consent of the Agents, the Company will not, directly or
indirectly, offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Stock (other than the Placement Shares offered pursuant to this Agreement) or securities convertible into or exchangeable for Common
Stock, warrants or any rights to purchase or acquire, Common Stock during the period beginning on the third (3rd) Trading Day immediately prior to the date on which any Placement Notice is
delivered to Agents hereunder and ending on the third (3rd) Trading Day immediately following the final Settlement Date with respect to Placement Shares sold pursuant to such Placement Notice (or,
if the Placement Notice has been terminated or suspended prior to the sale of all Placement Shares covered by a Placement Notice, the date of such suspension or termination); and will not directly or indirectly in any other “at the market”
or continuous equity transaction offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Stock (other than the Placement Shares offered pursuant to this Agreement) or securities convertible into or
exchangeable for Common Stock, warrants or any rights to purchase or acquire, Common Stock prior to the sixtieth (60th) day immediately following the termination of this Agreement;
provided, however, that such restrictions will not be required in connection with the Company’s issuance or sale of (i) Common Stock, options to purchase Common Stock, restricted stock units or Common Stock issuable upon the
exercise of options or the vesting and settlement of restricted stock units, pursuant to any employee or director stock option or benefits plan, stock ownership plan or dividend reinvestment plan (but not Common Stock subject to a waiver to exceed
plan limits in its dividend reinvestment plan) of the Company whether now in effect or hereafter implemented, (ii) inducement equity awards or shares issuable pursuant to inducement equity awards, (iii) Common Stock issuable upon
conversion of securities or the exercise of warrants, options or other rights in effect or outstanding, and disclosed in filings by the Company available on EDGAR or otherwise in writing to the Agents, (iv) Common Stock or securities
convertible into or exchangeable for Common Stock in privately negotiated transactions to vendors, customers, strategic partners or potential strategic partners conducted in a manner so as not to be integrated with the offering of Common Stock
hereby, and (v) Common Stock or securities convertible into or exchangeable for shares of Common Stock as consideration for mergers, acquisitions, other business combinations or strategic alliances occurring after the date of this Agreement
which are not issued for capital raising purposes. 

  
 22 













 (i)    Change of Circumstances. The Company will, at any time
during the pendency of a Placement Notice advise the Agents promptly after it shall have received notice or obtained knowledge thereof, of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or
other document required to be provided to the Agents pursuant to this Agreement. 
 (j)    Due Diligence
Cooperation. The Company will cooperate with any reasonable due diligence review conducted by the Agents or their representatives in connection with the transactions contemplated hereby, including, without limitation, providing information and
making available documents and senior corporate officers, during regular business hours and at the Company’s principal offices, as the Agents may reasonably request. 

(k)    Required Filings Relating to Placement of Placement Shares. The Company agrees that on such dates as the
Securities Act shall require, the Company will (i) file a prospectus supplement with the Commission under the applicable paragraph of Rule 424(b) under the Securities Act (each and every filing date under Rule 424(b), a “Filing
Date”), which prospectus supplement will set forth, within the relevant period, the amount of Placement Shares sold through the Agents, the Net Proceeds to the Company and the compensation payable by the Company to the Agents with
respect to such Placement Shares, and (ii) deliver such number of copies of each such prospectus supplement to each exchange or market on which such sales were effected as may be required by the rules or regulations of such exchange or market.

 (l)    Representation Dates; Certificate. (1) On or prior to the date of the first Placement Notice and
(2) each time the Company: 
 (i) files the Prospectus relating to the Placement Shares or amends or supplements (other than a
prospectus supplement relating solely to an offering of securities other than the Placement Shares) the Registration Statement or the Prospectus relating to the Placement Shares by means of a post-effective amendment, sticker, or supplement but not
by means of incorporation of documents by reference into the Registration Statement or the Prospectus relating to the Placement Shares; 

(ii) files an annual report on Form 10-K under the Exchange Act (including any Form 10-K/A containing amended financial information or a material amendment to the previously filed Form 10-K); 

(iii) files its quarterly reports on Form 10-Q under the Exchange Act; or 

(iv) files a current report on Form 8-K containing amended financial information (other than
information “furnished” pursuant to Items 2.02 or 7.01 of Form 8-K or to provide disclosure pursuant to Item 8.01 of Form 8-K relating to the
reclassification of certain properties as discontinued operations in accordance with Statement of Financial Accounting Standards No. 144) under the Exchange Act (each date of filing of one or more of the documents referred to in clauses
(i) through (iv) shall be a “Representation Date”); 
 the Company shall furnish the Agents (but in the case of clause
(iv) above only if the Agents reasonably determine that the information contained in such Form 8-K is material) with a certificate dated as of the Representation Date, in the form attached hereto as
Exhibit A hereto, 

  
 23 













 
modified, as necessary, to relate to the Registration Statement and the Prospectus as amended or supplemented. The requirement to provide a certificate under this
Section 7(l) shall be waived for any Representation Date occurring at a time during which no Placement Notice is pending or a Suspension is in effect, which waiver shall continue until the earlier to occur of the date the
Company delivers instructions for the sale of Placement Shares hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date. Notwithstanding the foregoing, if the Company
subsequently decides to sell Placement Shares following a Representation Date when a Suspension was in effect and did not provide the Agents with a certificate under this Section 7(l), then before the Company delivers the
instructions for the sale of Placement Shares or the Agents sell any Placement Shares pursuant to such instructions, the Company shall provide the Agents with a certificate in conformity with this Section 7(l) dated as of
the date that the instructions for the sale of Placement Shares are issued. 
 (m)    Legal Opinion. (1) On
or prior to the date of the first Placement Notice and (2) within five (5) Trading Days of each Representation Date with respect to which the Company is obligated to deliver a certificate pursuant to Section 7(l)
for which no waiver is applicable and excluding the date of this Agreement, the Company shall cause to be furnished to the Agents a written opinion of Latham & Watkins LLP (“Company Counsel”), or other counsel
reasonably satisfactory to the Agents, in form and substance reasonably satisfactory to the Agents and their counsel, substantially similar to the form previously provided to the Agents and their counsel, modified, as necessary, to relate to the
Registration Statement and the Prospectus as then amended or supplemented; provided, however, the Company shall be required to furnish to the Agents no more than one opinion hereunder per calendar quarter; provided,
further, that in lieu of such opinions for subsequent periodic filings under the Exchange Act, counsel may furnish the Agents with a letter (a “Reliance Letter”) to the effect that the Agents may rely on a prior
opinion delivered under this Section 7(m) to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and the
Prospectus as amended or supplemented as of the date of the Reliance Letter). Prior to the date of the first Placement Notice, the Company shall cause to be furnished to the Agents a written opinion of Mayer Brown LLP, as counsel for the Company
with respect to intellectual property matters, in form and substance reasonably satisfactory to the Agents and their counsel. 

(n)    Comfort Letter. (1) On or prior to the date of the first Placement Notice and (2) within five
(5) Trading Days of each Representation Date with respect to which the Company is obligated to deliver a certificate pursuant to Section 7(l) for which no waiver is applicable and excluding the date of this Agreement,
the Company shall cause its independent registered public accounting firm to furnish the Agents a letter (the “Comfort Letters”), dated the date the Comfort Letter is delivered, which shall meet the requirements set forth in
this Section 7(n); provided, that if requested by the Agents, the Company shall cause a Comfort Letter to be furnished to the Agents within ten (10) Trading Days of the date of occurrence of any material
transaction or event, including the restatement of the Company’s financial statements. The Comfort Letter from the Company’s independent registered public accounting firm shall be in a form and substance reasonably satisfactory to the
Agents, (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act and the PCAOB, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the
financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”)
and (iii) updating 

  
 24 













 
the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the Registration
Statement and the Prospectus, as amended and supplemented to the date of such letter. 
 (o)    Market
Activities. The Company will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or might reasonably be expected to constitute, the stabilization or manipulation of the price of any security
of the Company to facilitate the sale or resale of Common Stock or (ii) sell, bid for, or purchase Common Stock in violation of Regulation M, or pay anyone any compensation for soliciting purchases of the Placement Shares other than the Agents.

 (p)    Investment Company Act. The Company will conduct its affairs in such a manner so as to reasonably
ensure that neither it nor any of its subsidiaries will be or become, at any time prior to the termination of this Agreement, required to register as an “investment company,” as such term is defined in the Investment Company Act. 

(q)    No Offer to Sell. Other than an Issuer Free Writing Prospectus approved in advance by the Company and the
Agents in their capacity as agents hereunder, neither the Agents nor the Company (including its agents and representatives, other than the Agents in their capacity as such) will make, use, prepare, authorize, approve or refer to any written
communication (as defined in Rule 405 under the Securities Act), required to be filed with the Commission, that constitutes an offer to sell or solicitation of an offer to buy Placement Shares hereunder. 

(r)    Blue Sky and Other Qualifications. The Company will use its commercially reasonable efforts, in
cooperation with the Agents, to qualify the Placement Shares for offering and sale, or to obtain an exemption for the Placement Shares to be offered and sold, under the applicable securities laws of such states and other jurisdictions (domestic or
foreign) as the Agents may designate and to maintain such qualifications and exemptions in effect for so long as required for the distribution of the Placement Shares (but in no event for less than one year from the date of this Agreement);
provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to
subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Placement Shares have been so qualified or exempt, the Company will file such statements and
reports as may be required by the laws of such jurisdiction to continue such qualification or exemption, as the case may be, in effect for so long as required for the distribution of the Placement Shares (but in no event for less than one year from
the date of this Agreement). 
 (s)    Sarbanes-Oxley Act. The Company and the subsidiaries will maintain and
keep accurate books and records reflecting their assets and maintain internal accounting controls in a manner designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles and including those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions
and dispositions of the assets of the Company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of the Company’s consolidated financial statements in accordance with generally accepted
accounting principles, (iii) that receipts and expenditures of the Company are being made only in accordance with management’s and the 

  
 25 













 
Company’s directors’ authorization, and (iv) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the
Company’s assets that could have a material effect on its financial statements. The Company and the subsidiaries will maintain such controls and other procedures, including, without limitation, those required by Sections 302 and 906 of the
Sarbanes-Oxley Act, and the applicable regulations thereunder that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and
reported, within the time periods specified in the Commission’s rules and forms, including, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or
submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely
decisions regarding required disclosure and to ensure that material information relating to the Company or the subsidiaries is made known to them by others within those entities, particularly during the period in which such periodic reports are
being prepared. 
 (t)    Secretary’s Certificate; Further Documentation. On or prior to the date of the
first Placement Notice, the Company shall deliver to the Agents a certificate of the Secretary of the Company and attested to by an executive officer of the Company, dated as of such date, certifying as to (i) the Certificate of Incorporation
of the Company, (ii) the By-laws of the Company, (iii) the resolutions of the Board of Directors of the Company authorizing the execution, delivery and performance of this Agreement and the issuance
of the Placement Shares and (iv) the incumbency of the officers duly authorized to execute this Agreement and the other documents contemplated by this Agreement. Within five (5) Trading Days of each Representation Date, the Company shall
have furnished to the Agents such further information, certificates and documents as the Agents may reasonably request. 

8.    Payment of Expenses. The Company will pay all expenses incident to the performance of its obligations under
this Agreement, including (i) the preparation and filing of the Registration Statement, including any fees required by the Commission, and the printing or electronic delivery of the Prospectus as originally filed and of each amendment and
supplement thereto, in such number as the Agents shall deem necessary, (ii) the printing and delivery to the Agents of this Agreement and such other documents as may be required in connection with the offering, purchase, sale, issuance or
delivery of the Placement Shares, (iii) the preparation, issuance and delivery of the certificates, if any, for the Placement Shares to the Agents, including any stock or other transfer taxes and any capital duties, stamp duties or other duties
or taxes payable upon the sale, issuance or delivery of the Placement Shares to the Agents, (iv) the fees and disbursements of the counsel, accountants and other advisors to the Company, (v) the reasonable and documented fees and expenses
of the Agents including but not limited to the reasonable and documented fees and expenses of the counsel to the Agents, payable upon the execution of this Agreement, in an aggregate amount not to exceed $75,000 in connection with the execution of
this Agreement to both Agents collectively, and $25,000 for each program “refresh” executed pursuant to this Agreement, (vi) the qualification or exemption of the Placement Shares under state securities laws in accordance with the
provisions of Section 7(r) hereof, including filing fees, but excluding fees of the Agents’ counsel, (vii) the printing and delivery to the Agents of copies of any Permitted Issuer Free Writing Prospectus and the
Prospectus and any amendments or supplements thereto in such number as the Agents shall deem necessary, (viii) the preparation, 

  
 26

the cap, set forth in clause (v) above), and (xi) the fees and expenses incurred in connection with the listing of the Placement Shares on the Exchange. 

9.    Conditions to Agents’ Obligations. The obligations of the Agents hereunder with respect to a Placement
will be subject to the continuing accuracy and completeness of the representations and warranties made by the Company herein, to the due performance by the Company of its obligations hereunder, to the completion by the Agents of a due diligence
review satisfactory to it in their reasonable judgment, and to the continuing satisfaction (or waiver by the Agents in their sole discretion) of the following additional conditions: 

(a)    Registration Statement Effective. The Registration Statement shall have become effective and shall be
available for the (i) resale of all Placement Shares issued to the Agents and not yet sold by the Agents and (ii) sale of all Placement Shares contemplated to be issued by any Placement Notice. 

(b)    No Material Notices. None of the following events shall have occurred and be continuing: (i) receipt by
the Company of any request for additional information from the Commission or any other federal or state Governmental Authority during the period of effectiveness of the Registration Statement, the response to which would require any post-effective
amendments or supplements to the Registration Statement or the Prospectus; (ii) the issuance by the Commission or any other federal or state Governmental Authority of any stop order suspending the effectiveness of the Registration Statement or
the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Placement Shares for sale in any jurisdiction
or the initiation or threatening of any proceeding for such purpose; or (iv) the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus or any material document incorporated or deemed to
be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, the Prospectus or material documents incorporated so that, in the case of the Registration Statement, it
will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, that in the case of the Prospectus, it will not contain an
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(c)    No Misstatement or Material Omission. Agents shall not have advised the Company that the Registration
Statement or Prospectus, or any amendment or supplement thereto, contains an untrue statement of fact that in the Agents’ reasonable opinion is material, or omits to state a fact that in the Agents’ reasonable opinion is material and is
required to be stated therein or is necessary to make the statements therein not misleading. 
 (d)    Material
Changes. Except as contemplated in the Prospectus, or disclosed in the Company’s reports filed with the Commission, there shall not have been any material adverse change in the authorized capital stock of the Company or any Material Adverse
Effect or 

  
 27 













 
any development that would cause a Material Adverse Effect, or a downgrading in or withdrawal of the rating assigned to any of the Company’s securities (other than asset backed securities)
by any rating organization or a public announcement by any rating organization that it has under surveillance or review its rating of any of the Company’s securities (other than asset backed securities), the effect of which, in the case of any
such action by a rating organization described above, in the reasonable judgment of the Agents (without relieving the Company of any obligation or liability it may otherwise have), is so material as to make it impracticable or inadvisable to proceed
with the offering of the Placement Shares on the terms and in the manner contemplated in the Prospectus. 

(e)    Legal Opinions. The Agents shall have received the opinions of Company Counsel required to be delivered
pursuant to Section 7(m) on or before the date on which such delivery of such opinions is required pursuant to Section 7(m).

Stock shall not have been delisted from the Exchange. 
 (i)    Other Materials. On each date on which the
Company is required to deliver a certificate pursuant to Section 7(l), the Company shall have furnished to the Agents such appropriate further information, opinions, certificates, letters and other documents as the Agents
may reasonably request. All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof. 

(j)    Securities Act Filings Made. All filings with the Commission required by Rule 424 under the Securities Act
to have been filed prior to the issuance of any Placement Notice hereunder shall have been made within the applicable time period prescribed for such filing by Rule 424.

Exchange, subject only to notice of issuance, or (ii) the Company shall have filed an application for listing of the Placement Shares on the Exchange at, or prior to, the issuance of any Placement Notice and the Exchange shall have reviewed
such application and not provided any objections thereto. 
 (l)    FINRA. If applicable, FINRA shall have raised
no objection to the terms of this offering and the amount of compensation allowable or payable to the Agents as described in the Prospectus. 

  
 28 













 (m)    No Termination Event. There shall not have occurred any
event that would permit the Agents to terminate this Agreement pursuant to Section 12(a). 

10.    Indemnification and Contribution. 

(a)    Company Indemnification. The Company agrees to indemnify and hold harmless the Agents, their affiliates and
their affiliates’ respective partners, members, directors, officers, employees and agents and each person, if any, who controls the applicable Agent or any affiliate within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act as follows: 
 (i)    against any and all loss, liability, claim, damage and expense whatsoever, as
incurred, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a
material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any related Issuer Free Writing Prospectus or
the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading; 
 (ii)    against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or
several, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any Governmental Authority, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or
omission, or any such alleged untrue statement or omission; provided that (subject to Section 10(d) below) any such settlement is effected with the written consent of the Company, which consent shall not unreasonably
be delayed or withheld; and 
 (iii)    against any and all expense whatsoever, as incurred (including the reasonable
and documented fees and disbursements of counsel), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Authority, commenced or threatened, or any claim
whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission (whether or not a party), to the extent that any such expense is not paid under (i) or (ii) above, 

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of
any untrue statement or omission or alleged untrue statement or omission made solely in reliance upon and in conformity with the Agent Information (as defined below). 

(b)    Agent Indemnification. Each Agent, severally and not jointly, agrees to indemnify and hold harmless the
Company and its directors and each officer of the Company 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
against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 10(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendments thereto), the Prospectus (or 

  
 29 













 
any amendment or supplement thereto) or any Issuer Free Writing Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information relating to such Agent and
furnished to the Company in writing by such Agent expressly for use therein. The Company hereby acknowledges that the only information that the Agents have furnished to the Company expressly for use in the Registration Statement, the Prospectus or
any Issuer Free Writing Prospectus (or any amendment or supplement thereto) are the statements set forth in the seventh and eighth paragraphs under the caption “Plan of Distribution” in the Prospectus (the “Agent
Information”). 
 (c)    Procedure. Any party that proposes to assert the right to be indemnified
under this Section 10 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this
Section 10, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from
(i) any liability that it might have to any indemnified party otherwise than under this Section 10 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this
Section 10 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it
notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the
commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the
indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any other legal expenses except as provided below and except for the reasonable and documented
costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel
will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of
counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based on advice of counsel
to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying
party has not in fact employed counsel to assume the defense of such action or counsel reasonably satisfactory to the indemnified party, in each case, within a reasonable time after receiving notice of the commencement of the action; in each of
which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm (plus local counsel) admitted to practice in such jurisdiction at any one time for all such indemnified party or
parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly after the indemnifying party receives a written invoice relating to fees, disbursements and other charges. An indemnifying party will not,
in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent 

  
 30 













 
of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this
Section 10 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (1) includes an express and unconditional release of each indemnified party, in form and substance
reasonably satisfactory to such indemnified party, from all liability arising out of such litigation, investigation, proceeding or claim and (2) does not include a statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party. 
 (d)    Settlement Without Consent if Failure to Reimburse. If an
indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable and documented fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature
contemplated by Section 10(a)(ii) effected without its written consent if (1) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (2) such
indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (3) such indemnifying party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement. 
 (e)    Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 10 is applicable in accordance with its terms but for any reason is held to be unavailable or insufficient
from the Company or an Agent, the Company and such Agent will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding or any claim asserted) to which the Company and the Agents may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and
the Agents on the other hand. The relative benefits received by the Company on the one hand and the Agents on the other hand shall be deemed to be in the same proportion as the total net proceeds from the sale of the Placement Shares (before
deducting expenses) received by the Company bear to the total compensation received by the Agents from the sale of Placement Shares on behalf of the Company. If, but only if, the allocation provided by the foregoing sentence is not permitted by
applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and such
Agent, on the other hand, with respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering.
Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or
such Agent, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Agent agree that it would not be just and equitable if contributions
pursuant to this Section 10(e) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for the purpose of this
Section 10(e), any legal or other expenses 

  
 31 













 
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section 10(c) hereof.
Notwithstanding the foregoing provisions of this Section 10(e), no Agent shall be required to contribute any amount in excess of the commissions received by such Agent under this Agreement and no person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this
Section 10(e), any person who controls a party to this Agreement within the meaning of the Securities Act, any affiliates of an Agent and any officers, directors, partners, employees or agents of an Agent or any of its
affiliates, will have the same rights to contribution as that party, and each director of the Company and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each
case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this
Section 10(e), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 10(e) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except
for a settlement entered into pursuant to the last sentence of Section 10(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is
required pursuant to Section 10(c) hereof. The Agents’ respective obligations to contribute pursuant to this section are several in proportion to the respective number of Placement Shares they have sold hereunder, and
not joint. 
 11.    Representations and Agreements to Survive Delivery. The indemnity and contribution
agreements contained in Section 10 of this Agreement and all representations and warranties of the Company herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of
(i) any investigation made by or on behalf of any Agent, any controlling persons, or the Company (or any of their respective officers, directors, employees or controlling persons), (ii) delivery and acceptance of the Placement Shares and
payment therefor or (iii) any termination of this Agreement. 
 12.    Termination. 

(a)    Either Agent may terminate this Agreement, by notice to the Company, as hereinafter specified at any time
(1) if there has been, since the time of execution of this Agreement or since the date as of which information is given in the Prospectus, any change, or any development or event involving a prospective change, in the condition, financial or
otherwise, or in the business, properties, earnings, results of operations or prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, which individually or in the
aggregate, in the sole judgment of such Agent is material and adverse and makes it impractical or inadvisable to market the Placement Shares or to enforce contracts for the sale of the Placement Shares, (2) if there has occurred any material
adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in
national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of such Agent, impracticable 

  
 32 













 
or inadvisable to market the Placement Shares or to enforce contracts for the sale of the Placement Shares, (3) if trading in the Common Stock has been suspended or limited by the Commission
or the Exchange, or if trading generally on the Exchange has been suspended or limited, or minimum prices for trading have been fixed on the Exchange, (4) if any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market shall have occurred and be continuing, (5) if a major disruption of securities settlements or clearance services in the United States shall have
occurred and be continuing, or (6) if a banking moratorium has been declared by either U.S. Federal or New York authorities. Any such termination shall be without liability of any party to any other party except that the provisions of
Section 8 (Payment of Expenses), Section 10 (Indemnification and Contribution), Section 11 (Representations and Agreements to Survive Delivery),
Section 17 (Governing Law and Time; Waiver of Jury Trial) and Section 18 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. If an Agent elects
to terminate this Agreement as provided in this Section 12(a), such Agent shall provide the required notice as specified in Section 13 (Notices). For the avoidance of doubt, the termination by one
Agent of its rights and obligations under this Agreement pursuant to this Section 12(a) shall not affect the rights and obligations of the other Agent under this Agreement. 

(b)    The Company shall have the right, by giving five (5) days’ notice as hereinafter specified to terminate
this Agreement, with respect to such Agent’s rights and obligations under this Agreement, in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party
except that the provisions of Section 8, Section 10, Section 11, Section 17 and Section 18 hereof shall remain in full
force and effect notwithstanding such termination. 
 (c)    Each of the Agents shall have the right, by giving five
(5) days’ notice as hereinafter specified to terminate this Agreement in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the
provisions of Section 8, Section 10, Section 11, Section 17 and Section 18 hereof shall remain in full force and effect
notwithstanding such termination. For the avoidance of doubt, the termination by one Agent of its rights and obligations under this Agreement pursuant to this Section 12(c) shall not affect the rights and obligations of the
other Agent under this Agreement. 
 (d)    This Agreement shall remain in full force and effect unless terminated
pursuant to Sections 12(a), (b), or (c) above, upon the issuance and sale of all of the Placement Shares through the Agents on the terms and subject to the conditions set forth herein, or otherwise by mutual agreement of
the parties; provided, however, that any such termination by mutual agreement shall in all cases be deemed to provide that Section 8, Section 10, Section 11,
Section 17 and Section 18 shall remain in full force and effect. Upon termination of this Agreement, the Company shall not have any liability to an Agent for any discount, commission or other
compensation with respect to any Placement Shares not otherwise sold by an Agent under this Agreement. 
 (e)    Any
termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice by
an Agent or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Placement Shares, such Placement Shares shall settle in accordance with the provisions of this Agreement.

for such purpose. Each such notice or other communication shall be deemed given (i) when delivered personally or by verifiable facsimile transmission (with an original to follow) on or before 4:30 p.m., New York City time, on a Business

 An electronic communication
(“Electronic Notice”) shall be deemed written notice for purposes of this Section 13 if sent to the electronic mail address specified herein or by the receiving party under separate cover. Electronic Notice shall be
deemed received at the time the party sending Electronic Notice receives verification of receipt by the receiving party. Any party receiving Electronic Notice may request and shall be entitled to receive the notice on paper, in a nonelectronic form
(“Nonelectronic Notice”) which shall be sent to the requesting party within ten (10) days of receipt of the written request for Nonelectronic Notice. 

14.    Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Company and the
Agents and their respective successors and the parties referred to in Section 10 hereof. References to any of the parties contained in this Agreement shall be deemed to include the successors and permitted assigns of such party. Nothing in this
Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement. Neither party may assign its rights or obligations under this Agreement without the prior written consent of the other party; provided, however, that the Agents may assign their rights and
obligations hereunder to an affiliate thereof without obtaining the Company’s consent. 
 15.    Adjustments for
Stock Splits. The parties acknowledge and agree that all share-related numbers contained in this Agreement shall be adjusted to take into account any stock split, stock dividend or similar event effected with respect to the Placement Shares.

 16.    Entire Agreement; Amendment; Severability; Waiver. This Agreement (including all schedules and exhibits
attached hereto and Placement Notices issued pursuant hereto) constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject
matter hereof. Neither this Agreement nor any term hereof may be amended except pursuant to a written instrument executed by the Company and the Agents. In the event that any one or more of the provisions contained herein, or the application thereof
in any circumstance, is held invalid, illegal or unenforceable as written by a court of competent jurisdiction, then such provision shall be given full force and effect to the fullest possible extent that it is valid, legal and enforceable, and the
remainder of the terms and provisions herein shall be construed as if such invalid, illegal or 

  
 35 













 
unenforceable term or provision was not contained herein, but only to the extent that giving effect to such provision and the remainder of the terms and provisions hereof shall be in accordance
with the intent of the parties as reflected in this Agreement. No implied waiver by a party shall arise in the absence of a waiver in writing signed by such party. No failure or delay in exercising any right, power, or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power, or privilege hereunder. 

17.    GOVERNING LAW AND TIME; WAIVER OF JURY TRIAL. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME. EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

18.    CONSENT TO JURISDICTION. EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF
THE STATE AND FEDERAL COURTS SITTING IN THE CITY OF NEW YORK, BOROUGH OF MANHATTAN, FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH ANY TRANSACTION CONTEMPLATED HEREBY, AND HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT IN
ANY SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, THAT SUCH SUIT, ACTION OR PROCEEDING IS BROUGHT IN AN INCONVENIENT FORUM OR THAT THE VENUE OF SUCH SUIT, ACTION OR PROCEEDING IS
IMPROPER. EACH PARTY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF (CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED) TO SUCH PARTY
AT THE ADDRESS IN EFFECT FOR NOTICES TO IT UNDER THIS AGREEMENT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE
PROCESS IN ANY MANNER PERMITTED BY LAW. 
 19.    Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed Agreement by one party to the other may be made by facsimile or electronic transmission. 

20.    Construction. The section and exhibit headings herein are for convenience only and shall not affect the
construction hereof. References herein to any law, statute, ordinance, code, regulation, rule or other requirement of any Governmental Authority shall be deemed to refer to such law, statute, ordinance, code, regulation, rule or other requirement of
any Governmental Authority as amended, reenacted, supplemented or superseded in whole or in part and in effect from time to time and also to all rules and regulations promulgated thereunder.

 21.    Permitted Free Writing Prospectuses. The Company
represents, warrants and agrees that, unless it obtains the prior written consent of each of the Agents, and each of the Agents represents, warrants and agrees that, unless it obtains the prior written consent of the Company, it has not made and
will not make any offer relating to the Placement Shares that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the
Commission. Any such free writing prospectus consented to by the Agents or by the Company, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents and warrants that it has treated and
agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free
Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. For the purposes of clarity, the parties hereto agree that all free writing prospectuses, if any, listed in
Exhibit B hereto are Permitted Free Writing Prospectuses. 
 22.    Absence of Fiduciary
Relationship. The Company acknowledges and agrees that: 
 (a)    the Agents are acting solely as agents in
connection with the public offering of the Placement Shares and in connection with each transaction contemplated by this Agreement and the process leading to such transactions, and no fiduciary or advisory relationship between the Company or any of
its respective affiliates, stockholders (or other equity holders), creditors or employees or any other party, on the one hand, and the Agents, on the other hand, has been or will be created in respect of any of the transactions contemplated by this
Agreement, irrespective of whether or not the Agents have advised or are advising the Company on other matters, and the Agents have no obligation to the Company with respect to the transactions contemplated by this Agreement except the obligations
expressly set forth in this Agreement; 
 (b)    it is capable of evaluating and understanding, and understands and
accepts, the terms, risks and conditions of the transactions contemplated by this Agreement; 
 (c)    neither the
Agents nor their affiliates have provided any legal, accounting, regulatory or tax advice with respect to the transactions contemplated by this Agreement and it has consulted its own legal, accounting, regulatory and tax advisors to the extent it
has deemed appropriate; 
 (d)    it is aware that the Agents and their affiliates are engaged in a broad range of
transactions which may involve interests that differ from those of the Company and the Agents and their affiliates have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency
relationship or otherwise; and 
 (e)    it waives, to the fullest extent permitted by law, any claims it may have
against the Agents or their affiliates for breach of fiduciary duty or alleged breach of fiduciary duty in connection with the sale of Placement Shares under this Agreement and agrees that the Agents and their affiliates shall not have any liability
(whether direct or indirect, in contract, tort or otherwise) to it in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on its behalf or in right of it or the Company, employees or creditors of Company. 

  
 37
