ARTICLE 2
Right of First Offer; Right of First Refusal
2.1    Reserved.
2.2    Right of First Offer to Purchase Certain ROFO Assets.
(a)    Each ROFO Asset Owner hereby grants to Ergon a right of first offer with respect to any ROFO Asset to the extent that such ROFO Asset Owner proposes to Transfer any ROFO Asset (other than to a Permitted Transferee) during the term of this Agreement.

2.3    ROFO Procedures.
(a)    In the event a ROFO Asset Owner proposes to Transfer any applicable ROFO Asset (other than to a Permitted Transferee) during the term of this Agreement (a “Proposed ROFO Transaction”), such ROFO Asset Owner shall, prior to entering into any such Proposed ROFO Transaction, first give notice in writing to Ergon (the “ROFO Notice”) of its intention to enter into such Proposed ROFO Transaction.  The ROFO Notice shall include any material terms, conditions and details as would be necessary for Ergon to make a responsive offer to enter into the Proposed ROFO Transaction with the applicable ROFO Asset Owner.  Ergon shall have 30 days following receipt of the ROFO Notice to propose an offer to enter into the Proposed ROFO Transaction with such ROFO Asset Owner (the “ROFO Response”).  The ROFO Response shall be in writing and shall set forth the terms and conditions (including the purchase price Ergon proposes to pay for the ROFO Asset and the other terms of the purchase) pursuant to which Ergon would be willing to enter into a binding agreement for the Proposed ROFO Transaction.  If no ROFO Response is delivered by Ergon within such 30-day period, then Ergon shall be deemed to have waived its right of first offer with respect to such ROFO Asset, except to the extent reinstated as provided in Section 2.3(e).
(b)    If Ergon timely delivers a ROFO Response in accordance with Section 2.3(a), then, unless the ROFO Response is rejected pursuant to written notice delivered by the applicable ROFO Asset Owner to Ergon within 30 days of the delivery of the ROFO Response, such ROFO Response shall be deemed to have been accepted by the applicable ROFO Asset Owner and the applicable ROFO Asset Owner shall enter into an agreement with Ergon or its Affiliate providing for the consummation of the Proposed ROFO Transaction upon the terms set forth in the ROFO Response. Unless otherwise agreed between the Partnership and Ergon, the terms of the purchase and sale agreement will include the following provisions (the “Acceptance Terms”):
(i)    Ergon will agree to deliver the purchase price entirely in cash;
(ii)    Ergon shall purchase the ROFO Assets “as is, where is”; 
(iii)    the ROFO Asset Owner will represent to Ergon that it has title to the ROFO Assets that is sufficient to operate the ROFO Assets in accordance with their historical use, subject to all recorded matters and all physical conditions in existence on the closing date for the purchase of the applicable ROFO Assets.  If Ergon desires to obtain any title insurance with respect to the ROFO Asset, the full cost and expense of obtaining the same (including the cost of title examination, document duplication and policy premium) shall be borne by Ergon;

4

(iv)    the ROFO Asset Owner will grant to Ergon the right, exercisable at Ergon’s risk and expense prior to closing of the Proposed ROFO Transaction, to make such surveys, tests and inspections of the ROFO Assets as Ergon may deem desirable, so long as such surveys, tests or inspections do not damage the ROFO Assets or interfere with the activities of the applicable ROFO Asset Owner; provided, however, that no invasive inspection or sampling of soil or materials shall be performed without the prior written consent of the ROFO Asset Owner, which may be withheld in its sole and absolute discretion;
(v)    Ergon will have the right to terminate its obligation to purchase the ROFO Asset under this Article 2 if the results of any title examination, survey, test or inspection obtained under Sections 2.3(b)(iii) and 2.3(b)(iv) are, in the reasonable opinion of Ergon, unsatisfactory;
(vi)    on the closing date set forth in the ROFO Response (such date to be not less than 90 and not more than 120 days after the date such ROFO Response is delivered to the ROFO Asset Owner (the “ROFO Drop Dead Date”)), the ROFO Asset Owner and Ergon shall close the purchase of the ROFO Assets on the terms set forth in the ROFO Response and on the Acceptance Terms, and in the event of any conflict between the terms set forth in the ROFO Response and the Acceptance Terms, the Acceptance Terms shall control;
(vii)    the ROFO Asset Owner and Ergon shall use commercially reasonable efforts to do or cause to be done all things that may be reasonably necessary or advisable to effectuate the consummation of any transactions contemplated by this Article 2, including causing its respective Affiliates to execute, deliver and perform all documents, notices, amendments, certificates, instruments and consents required in connection therewith; 
(viii)    neither the ROFO Asset Owner nor Ergon shall have any obligation to sell or buy the ROFO Assets if any of the consents referred to in Section 2.2(b) has not been obtained; and
(ix)    the ROFO Asset Owner and Ergon shall cooperate in good faith in obtaining all necessary governmental and other third-party approvals, waivers and consents required for the closing.  Any such closing shall be delayed (and the ROFO Drop Dead Date shall be extended), to the extent required, until the third Business Day following the expiration of any required waiting periods under the HSR Act; provided, however, that such ROFO Drop Dead Date shall not extended for more than 65 days following the original ROFO Drop Dead Date described in Section 2.3(b)(vi).
(c)    If the ROFO Asset Owner accepts or is deemed to have accepted the ROFO Response, but the closing of the Proposed ROFO Transaction between the ROFO Asset Owner and Ergon does not occur on or before the ROFO Drop Dead Date, as such date may be extended pursuant to Section 2.3(b)(ix) (other an as a result of a breach of this Agreement or the applicable purchase and sale agreement by the ROFO Asset Owner), then the ROFO Asset Owner shall be free to enter into a Proposed ROFO Transaction with any third party (i) on terms and conditions (excluding those relating to price) that are not more favorable in the aggregate to such third party than those proposed by Ergon in the ROFO Response and (ii) at a price equal to no less than 100% of the price offered by Ergon in the ROFO Response to such ROFO Asset Owner.
(d)    If Ergon has not timely delivered a ROFO Response as specified above with respect to a Proposed ROFO Transaction that is subject to a ROFO Notice, the applicable ROFO Asset Owner shall be free to enter into a Proposed ROFO Transaction with any third party on terms and conditions no more favorable to such third party than those set forth in the ROFO Notice.  If a ROFO Response with respect to such Proposed ROFO Transaction is rejected by the applicable ROFO Asset Owner, such ROFO Asset Owner shall be free to enter into a Proposed ROFO Transaction with any third party (i) on terms and conditions 

5

(excluding those relating to price) that are not more favorable in the aggregate to such third party than those proposed in respect of Ergon in the ROFO Response and (ii) at a price equal to no less than 100% of the price offered by Ergon in the ROFO Response to such ROFO Asset Owner.
(e)    If a Proposed ROFO Transaction with a third party is not consummated as provided in Section 2.3(c) or Section 2.3(d) within one year of, as applicable, the ROFO Drop Dead Date (with respect to a Proposed ROFO Transaction described in Section 2.3(c)) or Ergon’s failure to timely deliver a ROFO Response with respect to such Proposed ROFO Transaction that is subject to a ROFO Notice or the rejection by the ROFO Asset Owner of a ROFO Response (with respect to a Proposed ROFO Transaction described in Section 2.3(d)), then, in each case, the ROFO Asset Owner may not Transfer any ROFO Assets described in such ROFO Notice without complying again with the provisions of this Article 2, if and to the extent then applicable.
2.4    Right of First Refusal to Purchase Certain ROFR Assets. Subject to the terms and conditions set forth above (including, without limitation, Sections 2.1 through 2.3), if any ROFR Asset Owner proposes or intends to sell any ROFR Asset to a third party (other than a Permitted Transferee) during the ROFR Period then Ergon shall have the right to purchase the ROFR Assets (the "ROFR Right") on the following terms and conditions:
(a)    If any ROFR Asset Owner executes a contract or letter of intent to sell the ROFR Assets to such third party, which transaction is expected to close during the ROFR Period, such ROFR Asset Owner shall provide Ergon with written notice setting forth the ROFR Assets, the proposed sale price and other material terms and conditions upon which such ROFR Asset Owner intends to sell the ROFR Assets to a third party (the "Term ROFR Notice"). Within 30 days after it receives the Term ROFR Notice (the "Term ROFR Period"), Ergon may deliver written notice (the "Term ROFR Exercise Notice") to such ROFR Asset Owner that Ergon is exercising its ROFR Right and will purchase the ROFR Assets for the price and upon the terms and conditions contained in the Term ROFR Notice. If Ergon does not deliver the Term ROFR Exercise Notice to such ROFR Asset Owner during the Term ROFR Period, then such ROFR Asset Owner shall thereafter be free to sell the ROFR Assets to such third party substantially on the terms and conditions contained in the Term ROFR Notice or pursuant to higher or more favorable terms and conditions. 
(b)    Notwithstanding anything to the contrary contained herein, the ROFR Right shall not apply to any mortgage of the ROFR Asset or any portion thereof to secure the repayment of borrowings by the ROFR Asset Owner or any of its Affiliates. A foreclosure sale by such lender shall not be a sale to which the ROFR Right shall be applicable, and upon any such foreclosure sale the ROFR Right shall terminate automatically and be of no further force or effect notwithstanding the existence of, or any term contained in, any non-disturbance agreement from such ROFR Asset Owner’s lenders. In clarification of the foregoing, after any such foreclosure sale, the ROFR Right shall never apply. In the event of a foreclosure sale, to the extent that such ROFR Asset Owner receives notice thereof, such ROFR Asset Owner shall provide Ergon notice of such sale, including the date, time and place of sale, if known by such ROFR Asset Owner; such notice to be provided by such ROFR Asset Owner within five Business Days following such ROFR Asset Owner ‘s receipt of such information, if any. As used herein, "foreclosure sale" shall include a conveyance in lieu of foreclosure. It is the intention of the Parties that the ROFR Right be subordinate to any mortgage presently encumbering the ROFR Assets.

PIERIS PHARMACEUTICALS, INC. 

COMMON STOCK 

SALES AGREEMENT 

October 5, 2016 
 Cowen and Company, LLC 

599 Lexington Avenue 
 New York, NY 10022 

Ladies and Gentlemen: 
 Pieris Pharmaceuticals,
Inc., a Nevada corporation (the “Company”), confirms its agreement (this “Agreement”) with Cowen and Company, LLC (“Cowen”), 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 Cowen, acting as agent and/or principal, shares (the “Placement Shares”) of the Company’s common stock, par value $0.001 per share (the
“Common Stock”), having an aggregate offering price of up to $35,000,000.00. Notwithstanding anything to the contrary contained herein, the parties hereto agree that compliance with the limitation set forth in this
Section 1 on the number of shares of Common Stock issued and sold under this Agreement shall be the sole responsibility of the Company, and Cowen shall have no obligation in connection with such compliance. The issuance and sale of
Common Stock through Cowen 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”), although nothing
in this Agreement shall be construed as requiring the Company to use the Registration Statement (as defined below) to issue the Common Stock. 

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder
(collectively, the “Securities Act”), with the Commission a registration statement on Form S-3 (File No. 333-211844) 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 certain documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and
regulations thereunder (collectively, the “Exchange Act”). The Company has prepared a prospectus supplement specifically relating to the Placement Shares (the “Prospectus Supplement”) to the base
prospectus included as part of such registration statement. The Company has made available to Cowen, for use by Cowen, copies of the base prospectus included as part of such registration statement, as supplemented by the Prospectus Supplement,
relating to the Placement Shares. Except where the context otherwise requires, such registration statement, as amended when it became effective, 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 or deemed to be a part of such 

 
registration statement pursuant to Rule 430B or 462(b) of the Securities Act, is herein called the “Registration Statement.” The base prospectus, including all documents
incorporated therein by reference, included in the Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus and/or Prospectus Supplement have most recently been filed by the Company with
the Commission pursuant to Rule 424(b) under the Securities Act, together with any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act (“Rule 433”), relating to the Placement Shares
that (i) is required to be filed with the Commission by the Company or (ii) is exempt from filing pursuant to Rule 433(d)(5)(i), in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in
the form retained in the Company’s records pursuant to Rule 433(g), is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be
deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus
shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein. 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 any copy filed with the Commission pursuant to the Electronic Data Gathering Analysis and Retrieval System (“EDGAR”). 

2. Placements. Each time that the Company wishes to issue and sell the Placement Shares hereunder (each, a
“Placement”), it will notify Cowen by email notice (or other method mutually agreed to in writing by the parties) (a “Placement Notice”) containing the parameters in accordance with which it desires
the Placement Shares to be sold, which shall at a minimum include 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
Trading Day (as defined in Section 3) and any minimum price below which sales may not be made, a form of which containing such necessary minimum sales parameters is attached hereto as Schedule 1. The Placement Notice shall
originate from any of the individuals from the Company set forth on Schedule 2 (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 Cowen set
forth on Schedule 2, as such Schedule 2 may be amended in writing from time to time in accordance herewith. The Placement Notice shall be effective upon receipt by Cowen unless and until (i) in accordance with the
notice requirements set forth in Section 4, Cowen declines to accept the terms contained therein for any reason, in its sole discretion, (ii) the entire amount of the Placement Shares have been sold, (iii) in accordance with
the notice requirements set forth in Section 4, the Company suspends or terminates the Placement Notice for any reason, in the Company’s sole and absolute discretion, (iv) the Company issues a subsequent Placement Notice with
parameters superseding those contained in the earlier dated Placement Notice, or (v) this Agreement has been terminated under the provisions of Section 11. The amount of any discount, commission or other compensation to be paid by
the Company to Cowen in connection with the sale of the Placement Shares shall be calculated in accordance with the terms set forth in Schedule 3. It is expressly acknowledged and agreed that neither the Company nor Cowen will have any
obligation whatsoever with respect to a Placement or any Placement Shares unless and until the Company delivers a Placement Notice to Cowen and Cowen 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 Cowen. 

(a) Subject to the terms and conditions herein set forth, upon the Company’s delivery 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, Cowen, 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, Inc. (“Nasdaq”) to sell such Placement Shares up to the
amount specified, and otherwise in accordance with the terms of such Placement Notice. Cowen will provide written confirmation to the Company (including by email correspondence to each of the individuals of the Company set forth on Schedule
2, if receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other than via auto-reply) 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 volume-weighted average price of the Placement Shares sold, and the Net Proceeds (as defined below) payable to the
Company. Cowen may sell Placement Shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act, including without limitation sales made through Nasdaq, on any other existing
trading market for the Common Stock or to or through a market maker. If expressly authorized by the Company in a Placement Notice, Cowen may also sell Placement Shares in privately negotiated transactions. Notwithstanding the provisions of
Section 6(jj), Cowen shall not purchase Placement Shares for its own account as principal unless expressly authorized to do so by the Company in a Placement Notice. The Company acknowledges and agrees that (i) there can be no
assurance that Cowen will be successful in selling Placement Shares, and (ii) Cowen 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
Cowen to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law to sell such Placement Shares as required under this Section 3. For the purposes hereof, “Trading
Day” means any day on which the Company’s Common Stock is purchased and sold on the principal market on which the Common Stock is then listed or quoted. 

(b) During the term of this Agreement and notwithstanding anything to the contrary herein, neither Cowen nor any “affiliated
purchaser” (as such term is defined in Regulation M under the Exchange Act) of Cowen will engage in any activity prohibited by Regulation M under the Exchange Act or other anti-manipulation rules under the applicable securities laws. 

4. Suspension of Sales. 

(a) The Company or Cowen 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 2, if receipt of such correspondence is actually acknowledged by 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 2), suspend any sale of Placement Shares; provided, however, that such

  
 - 3 - 

 
suspension shall not affect or impair either party’s obligations with respect to any Placement Shares sold hereunder prior to the receipt of such notice. Each of the parties agrees that no
such notice under this Section 4 shall be effective against the other unless it is made to one of the individuals named on Schedule 2 hereto, as such schedule may be amended from time to time, and in accordance with
Section 12 hereunder. 
 (b) Notwithstanding any other provision of this Agreement, during any period in which the Company is in
possession of material non-public information, the Company and Cowen agree that (i) no sale of Placement Shares will take place, (ii) the Company shall not request the sale of any Placement Shares, and (iii) Cowen shall not be
obligated to sell or offer to sell any Placement Shares. 
 (c) If either Cowen or the Company has reason to believe that the exemptive
provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Common Stock, it shall promptly notify the other party, and Cowen may, at its sole discretion, suspend sales of the Placement Shares
under this Agreement. 
 5. Settlement. 

(a) Settlement of Placement Shares. Unless otherwise specified in the applicable Placement Notice, settlement for sales of
Placement Shares will occur on the third (3rd) 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” and the first such settlement date, the “First Delivery Date”). 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 Cowen at which such Placement Shares were sold, after deduction for (i) Cowen’s commission, discount or other compensation for such sales
payable by the Company pursuant to Section 2 hereof, (ii) any other amounts due and payable by the Company to Cowen hereunder pursuant to Section 7(g) (Expenses) hereof, and (iii) any transaction fees imposed by any
governmental or self-regulatory organization in respect of such sales. 
 (b) 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 Cowen’s or its designee’s account (provided Cowen shall have given the Company written notice of
such designee at least one (1) Trading Day prior to the Settlement Date) at The Depository Trust Company through its Deposit 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 tradeable, transferable, registered shares in good deliverable form. On each Settlement Date, Cowen 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 duly authorized 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 9(a) (Indemnification and Contribution) hereto, it will (i) hold Cowen harmless against any loss, claim, damage, or expense (including reasonable legal fees and
expenses), as incurred, arising out of or in connection with such default by the Company and (ii) pay to Cowen any commission, discount, or other compensation to which it would otherwise have been entitled absent such default.

(a) Compliance with Registration Requirements. The Registration Statement has been declared effective by the Commission under the

material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date, did not and, as of each of the Settlement Dates, if any, will not contain any untrue
statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the two
immediately preceding sentences do not apply to statements in or omissions from the Registration Statement, or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity

registered public accounting firm with respect to the Company and its subsidiaries as required by the Securities Act and the Exchange Act. 

(k) Preparation of the Financial Statements. The financial statements filed with the Commission and incorporated by reference in

and is in good standing in its country of domicile and each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the
failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change. Except as described in the Prospectus, all of the issued and outstanding equity interests of each Significant
Subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Company free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim. The Company does not own or control,

 (o) Non-Contravention of Existing Instruments; No
Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is in violation of its charter or by-laws or is in default (or, with the giving of notice or lapse of time, would be in default)
(“Default”) under any indenture, mortgage, loan or credit agreement, note, contract, franchise, lease or other instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound,
or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”), except for such Defaults as would not, individually or in the aggregate, result in a Material
Adverse Change. The Company’s execution, delivery and performance of this Agreement and consummation of the transactions contemplated hereby and by the Prospectus (i) have been duly authorized by all necessary corporate action and will not
result in any violation of the provisions of the charter or by-laws or other applicable organizational documents of the Company or any subsidiary, (ii) will not conflict with or constitute a breach of, or Default under, or result in the
creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, or require the consent of any other party to, any Existing Instrument, except for such conflicts, breaches,
Defaults, liens, charges or encumbrances as would not, individually or in the aggregate, result in a Material Adverse Change and (iii) will not result in any material violation of any law, administrative regulation or administrative or court
decree applicable to the Company or any subsidiary. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s
execution, delivery and performance of this Agreement and consummation of the transactions contemplated hereby and by the Prospectus, except such as have been obtained or made by the Company and are in full force and effect under the Securities Act,
the rules and regulations of Nasdaq, applicable state securities or blue sky laws and from the Financial Industry Regulatory Authority (“FINRA”). 

(p) No Material Actions or Proceedings. Except as disclosed in the Prospectus, there are no legal or governmental actions, suits
or proceedings pending or, to the best of the Company’s knowledge, threatened against or affecting the Company or any of its subsidiaries, or which any property owned or leased by, the Company or any of its subsidiaries is or may reasonably be
expected to become subject of, relating to environmental or discrimination matters, where in any such case there is a reasonable possibility that such action, suit or proceeding would reasonably be expected to result in a Material Adverse Change or
adversely affect the consummation of the transactions contemplated by this Agreement. No material labor dispute with the employees of the Company or any of its subsidiaries exists or, to the Company’s knowledge, is threatened or imminent.

permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses, other than 

  
 - 8 - 

 
those the failure to possess or own would not result in a Material Adverse Change, and neither the Company nor any subsidiary has received any written notice of proceedings relating to the
revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Change. 

(r) Tax Law Compliance. The Company and its consolidated subsidiaries have filed all necessary federal, state and foreign income,
property and franchise tax returns and have paid all taxes required to be paid by any of them through the date hereof and, if due and payable, any related or similar assessment, fine or penalty levied against any of them except as may be being
contested in good faith and by appropriate proceedings. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 6(k) above in respect of all federal, state and foreign

of recognized financial responsibility with policies in such amounts and with such deductibles and covering such risks as the Company reasonably considers to be in accordance with customary industry practices for the business in which it is engaged
and for companies of comparable size, market capitalization and stages of business and clinical development. The Company has no reason to believe that it or any subsidiary will not be able (i) to renew its existing insurance coverage as and
when such policies expire or (ii) to obtain comparable coverage from similar insurers as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change. 

(u) No Price Stabilization or Manipulation. The Company has not taken and will not take, directly or indirectly, any action
designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Placement Shares.

Item 404 of Regulation S-K under the Exchange Act, involving the Company or any subsidiary or any other person required to be described in the Prospectus which have not been described as required. 

(w) Exchange Act Compliance. The documents incorporated or deemed to be incorporated by reference in the Prospectus, at the time
they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act, and, when read together with the other information in the Prospectus, at the Settlement Dates, will

times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all jurisdictions, the rules and regulations
thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before
any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened.

agent, employee or affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”); and the
Company will not, directly or indirectly, use the proceeds of the offering of the Placement Shares hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the
purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC. 

(aa) Company’s Accounting System. The Company maintains a system of “internal control over financial reporting” (as
such term is defined in Rule 13a-15(f) under the Exchange Act that complies with the requirements of the Exchange Act and has been designed by its principal executive and principal financial officers, or persons under their supervision, to provide
reasonable assurances 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
U.S. GAAP and to maintain accountability for assets; (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 existing
assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company believes that as of the end of its most recent audited fiscal year, its internal control over financial reporting is effective. Except as
described in the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and
(B) 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.

to ensure that information required to be disclosed by the Company in 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 controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management to allow timely decisions regarding disclosures.
The Company has conducted evaluations of the effectiveness of their disclosure controls as required by Rule 13a-15 of the Exchange Act.

or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including without limitation, laws and regulations relating to emissions, discharges, releases or threatened
releases of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum and petroleum products (collectively, “Materials of Environmental Concern”), or otherwise relating to the manufacture,

location owned, leased or operated by the Company or any of its subsidiaries, now or in the past (collectively, “Environmental Claims”), pending or, to the Company’s knowledge, threatened against the Company or any of
its subsidiaries or any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law; and (iii) to the best of the Company’s
knowledge, there are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, emission, discharge, presence or disposal of any Material of Environmental Concern, that
reasonably could result in a violation of any Environmental Law or form the basis of a potential Environmental Claim against the Company or any of its subsidiaries or against any person or entity whose liability for any Environmental Claim the
Company or any of its subsidiaries has retained or assumed either contractually or by operation of law.

Rights or Intellectual Property Assets owned or used by the Company or its subsidiaries. To the knowledge of the Company, the Company and its subsidiaries’ respective businesses as now conducted do not give rise to any infringement of, any

by or against the parties thereto in accordance to its terms. The Company has complied in all material respects with, and to its knowledge is not in breach nor has received any asserted or threatened claim of breach of any Intellectual Property
license, and the Company has no knowledge of any breach or anticipated breach by any other person to any license for Intellectual Property Rights. Except as described in the Prospectus, no claim has been made against the Company alleging the
infringement by the Company of any Intellectual Property Right or franchise right of any person. The Company has taken all reasonable steps to protect, maintain and safeguard its Intellectual Property Rights, including the execution of appropriate
nondisclosure and confidentiality agreements, except where failure to do so would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. The consummation of the transactions contemplated by this
Agreement will not result in the loss or impairment of or payment of any additional amounts with respect to, nor require the consent of any other person in respect of, the Company’s right to own, use, or hold for use any of the Intellectual
Property Rights as owned, used or held for use in the conduct of the business as currently conducted.

asserting, or has knowledge of, any present or past failure to comply with or violation of any such Laws nor has the Company or any of the Significant Subsidiaries received any written notification of proceedings relating to the revocation or
modification of any license, permit, approval, certification, authorization or other governmental license. Except to the extent disclosed in the Registration Statement or the Prospectus, the pending and completed clinical, pre-clinical and other

authority requiring the termination, suspension, or clinical hold of any preclinical study or clinical trials, which termination, suspension, or clinical hold would reasonably be expected to have a Material Adverse Change. No filing or submission to
the FDA or any other regulatory body, to the knowledge of the Company, contains any material omission or, material false information.

(except normal advances for business expenses in the ordinary course of business) or guarantees or indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of the members of any of them. 

(ii) No Reliance. The Company has not relied upon Cowen or legal counsel for Cowen for any legal, tax or accounting advice in
connection with the offering and sale of the Placement Shares. 
 (jj) Cowen Purchases. The Company acknowledges and agrees that
Cowen has informed the Company that Cowen may, to the extent permitted under the Securities Act and the Exchange Act and applicable law, purchase and sell shares of Common Stock for its own account while this Agreement is in effect; provided,
that (i) no such purchase or sale shall take place while a Placement Notice is in effect (except to the extent Cowen may engage in sales of 

  
 - 13 - 

 
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 Cowen. 
 (kk) Compliance with Laws. The Company has not been advised, and has no
reason to believe, that it and each of its subsidiaries are not conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where failure to be so in compliance
would not result in a Material Adverse Change. 
 Any certificate signed by an officer of the Company and delivered to Cowen or to counsel for Cowen in
connection with this Agreement shall be deemed to be a representation and warranty by the Company to Cowen as to the matters set forth therein. 
 The
Company acknowledges that Cowen and, for purposes of the opinions to be delivered pursuant to Section 7 hereof, counsel to the Company and counsel to Cowen, will rely upon the accuracy and truthfulness of the foregoing representations
and hereby consents to such reliance. 
 7. Covenants of the Company. The Company covenants and agrees with Cowen that: 

(a) Registration Statement Amendments. After the date of this Agreement and during any period in which a Prospectus relating to
any Placement Shares is required to be delivered by Cowen under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act) (the “Prospectus Delivery
Period”), (i) the Company will notify Cowen 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 subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus or for additional information, (ii) the Company will
prepare and file with the Commission, promptly upon Cowen’s request, any amendments or supplements to the Registration Statement (insofar as it relates to the transactions contemplated hereby) or Prospectus that, in Cowen’s reasonable
opinion, may be necessary or advisable to comply with applicable law in connection with the distribution of the Placement Shares by Cowen (provided, however, that the failure of Cowen to make such request shall not relieve the Company of any
obligation or liability hereunder, or affect Cowen’s right to rely on the representations and warranties made by the Company in this Agreement); (iii) the Company will not file any amendment or supplement to the Registration Statement or
Prospectus, other than documents incorporated by reference, relating to the Placement Shares or a security convertible into the Placement Shares unless a copy thereof has been submitted to Cowen within a reasonable period of time before the filing
and Cowen has not reasonably objected thereto (provided, however, that the failure of Cowen to make such objection shall not relieve the Company of any obligation or liability hereunder, or affect Cowen’s right to rely on the
representations and warranties made by the Company in this Agreement) and the Company will furnish to Cowen 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, other than documents incorporated by reference, to be filed with the Commission as required
pursuant to the applicable paragraph of Rule 424(b) under the Securities Act. 

  
 - 14 - 

 (b) Notice of Commission Stop Orders. The Company will advise Cowen, 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. 
 (c) Delivery of Prospectus; Subsequent Changes. During the Prospectus Delivery Period,
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 (taking into account any extensions available under the Exchange Act) 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 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 Cowen 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; provided, however, that the
Company may delay any such amendment or supplement if, in the reasonable judgment of the Company, it is in the best interest of the Company to do so. Until such time as the Company shall have corrected such statement or omission or effected such
compliance, the Company shall not request that Cowen resume the offering of Placement Shares. 
 (d) Listing of Placement
Shares. During the Prospectus Delivery Period, the Company will use its commercially reasonable efforts to cause the Placement Shares to be listed on Nasdaq and to qualify the Placement Shares for sale under the securities laws of such
jurisdictions as Cowen reasonably designates and to continue such qualifications in effect so long as required for the distribution of the Placement Shares; provided, however, that the Company shall not be required in connection therewith to
qualify as a foreign corporation or dealer in securities or file a general consent to service of process in any jurisdiction. 

(e) Delivery of Registration Statement and Prospectus. The Company will furnish to Cowen and its 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 the
Prospectus Delivery Period (including all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities as Cowen may from time
to time reasonably request and, at Cowen’s 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 Cowen to the extent such document is available on EDGAR. 

  
 - 15 - 

 (f) Earnings Statement. 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 earnings statement covering a 12-month period that satisfies the provisions of Section 11(a) of and Rule
158 under the Securities Act. The Company’s compliance with the periodic reporting requirements of the Exchange Act shall be deemed to satisfy the requirements of this Section 7(f). 

(g) Expenses. The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated,
in accordance with the provisions of Section 11 hereunder, will pay the following expenses all incident to the performance of its obligations hereunder, including, but not limited to, expenses relating to (i) the preparation,
printing and filing of the Registration Statement and each amendment and supplement thereto, and of each Prospectus and of each amendment and supplement thereto, (ii) the preparation, issuance and delivery of the Placement Shares,
(iii) the qualification of the Placement Shares under securities laws in accordance with the provisions of Section 7(d) of this Agreement, including filing fees (provided, however, that any fees or disbursements of counsel for Cowen
in connection therewith shall be paid by Cowen except as set forth in (vii) below), (iv) the printing and delivery to Cowen of copies of the Prospectus and any amendments or supplements thereto, and of this Agreement, (v) the fees and
expenses incurred in connection with the listing or qualification of the Placement Shares for trading on Nasdaq, (vi) the filing fees and expenses, if any, of the Commission, (vii) the filing fees and associated legal expenses of
Cowen’s outside counsel for filings with the FINRA Corporate Financing Department , such legal expense reimbursement not to exceed $10,000 and, (viii) the reasonable fees and disbursements of Cowen’s counsel in an amount not to exceed
$50,000. 
 (h) Use of Proceeds. The Company will use the Net Proceeds as described in the Prospectus in the section entitled
“Use of Proceeds.” 
 (i) Notice of Other Sales. During the pendency of any Placement Notice given hereunder, and for
five (5) Trading Days following the termination of any Placement Notice given hereunder, the Company shall provide Cowen notice as promptly as reasonably possible before it offers to sell, contracts to sell, sells, grants any option to sell or
otherwise disposes of any shares of Common Stock (other than Placement Shares offered pursuant to the provisions of this Agreement) or securities convertible into or exchangeable for Common Stock, warrants or any rights to purchase or acquire Common
Stock; provided, that such notice shall not be required in connection with (i) the issuance, grant or sale of Common Stock, options to purchase shares of Common Stock or Common Stock issuable upon the exercise of options or other equity
awards pursuant to any stock option, stock bonus or other stock plan or arrangement described in the Prospectus or pursuant to any “inducement grant” or prospective employees of the Company, (ii) the issuance of securities in
connection with an acquisition, merger or sale or purchase of assets, (iii) the issuance or sale of Common Stock pursuant to any dividend reinvestment plan that the Company may adopt from time to time provided the implementation of such plan is
disclosed to Cowen in advance, (iv) any shares of Common Stock issuable upon the exchange, conversion or redemption of securities or the exercise of warrants, options or other rights in effect or outstanding or (v) the issuance of Common
Stock, or securities convertible into or exercisable for Common Stock, offered and sold in a privately negotiated transaction to vendors, customers, or strategic partners. 

  
 - 16 - 

 (j) Change of Circumstances. The Company will, at any time during the pendency of a
Placement Notice, advise Cowen promptly after it shall have received notice or obtained knowledge of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or other document provided to Cowen
pursuant to this Agreement. 
 (k) Due Diligence Cooperation. The Company will cooperate with any reasonable due diligence
review conducted by Cowen or its agents 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 Cowen may reasonably request. 
 (l) Required Filings Relating to Placement of Placement
Shares. The Company agrees that on or before 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 under Rule 424(b), a “Filing Date”), which prospectus supplement will set forth, within the relevant period, the amount of Placement Shares sold through Cowen, the Net Proceeds to the Company and the
compensation payable by the Company to Cowen with respect to such Placement Shares (provided that the Company may also satisfy its obligations under this Section 7(l)(i) by including such information in a filing under the Exchange Act),
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. 

(m) Representation Dates; Certificate. On or prior to the First Delivery Date and each time the Company subsequently thereafter
(i) files the Prospectus relating to the Placement Shares or amends or supplements the Registration Statement or the Prospectus relating to the Placement Shares (other than a prospectus supplement filed in accordance with
Section 7(l) of this Agreement) by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of document(s) by reference to the Registration Statement or the Prospectus relating to the Placement
Shares; (ii) files an annual report on Form 10-K under the Exchange Act; (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 a filing made in connection with the issuance of an earnings release or other information “furnished” under Items 2.02 or 7.01 of Form 8-K) 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 Cowen with a certificate, in the form attached hereto as Exhibit 7(m) within three (3) Trading Days of any
Representation Date if requested by Cowen. The requirement to provide a certificate under this Section 7(m) shall be waived for any Representation Date occurring at a time at which no Placement Notice is pending, which waiver shall
continue until the earlier to occur of the date the Company delivers a Placement Notice hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date; provided,
however, that such waiver shall not apply for any Representation Date on which the Company files its annual report on Form 10-K. Notwithstanding the foregoing, if the Company subsequently decides to sell Placement Shares following a
Representation Date when the Company relied on such waiver and did not provide Cowen with a certificate under this Section 7(m), then before the Company delivers the Placement Notice or Cowen sells any Placement Shares, the Company shall
provide Cowen with a certificate, in the form attached hereto as Exhibit 7(m), dated the date of the Placement Notice. 

  
 - 17 - 

 (n) Legal Opinion. On or prior to the First Delivery Date and within three
(3) Trading Days of each Representation Date with respect to which the Company is obligated to deliver a certificate pursuant to Section 7(m) for which no waiver is applicable, the Company shall cause to be furnished to Cowen a
written opinion of each of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. (“Company Counsel”) and Brownstein Hyatt Farber Schreck, LLP (“Company Nevada Counsel”), or other counsel satisfactory to Cowen, in form
and substance reasonably satisfactory to Cowen and its counsel, dated the date that the opinion is required to be delivered, modified, as necessary, to relate to the Registration Statement and the Prospectus as then amended or supplemented;
provided, however, that in lieu of such opinions for subsequent Representation Dates, each such counsel may furnish Cowen with a letter (a “Reliance Letter”) to the effect that Cowen may rely on a prior opinion
delivered under this Section 7(n) 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 at such Representation Date). 
 (o) Comfort Letter. On or prior to the First Delivery Date and within three
(3) Trading Days of each Representation Date with respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit 7(m) for which no waiver is applicable, the Company shall cause its independent
accountants to furnish Cowen letters (the “Comfort Letters”), dated the date the Comfort Letter is delivered, in form and substance satisfactory to Cowen, (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 Cowen in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and (iii) updating 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. 

(p) 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 the Placement Shares or (ii) sell, bid for, or purchase the
Placement Shares to be issued and sold pursuant to this Agreement, or pay anyone any compensation for soliciting purchases of the Placement Shares other than Cowen; provided, however, that the Company may bid for and purchase shares of its common
stock in accordance with Rule 10b-18 under the Exchange Act. 
 (q) Insurance. The Company and its subsidiaries shall maintain,
or cause to be maintained, insurance in such amounts and covering such risks as is reasonable and customary for the business for which it is engaged. 

(r) Compliance with Laws. The Company and each of its subsidiaries shall maintain, or cause to be maintained, all material
environmental permits, licenses and other authorizations required by federal, state and local law in order to conduct their businesses as described in the 

  
 - 18 - 

 
Prospectus, and the Company and each of its subsidiaries shall conduct their businesses, or cause their businesses to be conducted, in substantial compliance with such permits, licenses and
authorizations and with applicable environmental laws, except where the failure to maintain or be in compliance with such permits, licenses and authorizations could not reasonably be expected to result in a Material Adverse Change. 

(s) Investment Company Act. The Company will conduct its affairs in such a manner so as to reasonably ensure that neither it nor
its subsidiaries will be or become, at any time prior to the termination of this Agreement, an “investment company,” as such term is defined in the Investment Company Act, assuming no change in the Commission’s current interpretations
as to entities that are not considered an investment company. 
 (t) Securities Act and Exchange Act. The Company will use its
reasonable best efforts to comply with all requirements imposed upon it by the Securities Act and the Exchange Act as from time to time in force, so far as necessary to permit the continuance of sales of, or dealings in, the Placement Shares as
contemplated by the provisions hereof and the Prospectus. 
 (u) No Offer to Sell. Other than a free writing prospectus (as
defined in Rule 405 under the Securities Act) approved in advance by the Company and Cowen in its capacity as principal or agent hereunder, neither Cowen nor the Company (including its agents and representatives, other than Cowen in its 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. 
 (v) Sarbanes-Oxley Act. The Company and its subsidiaries will use their reasonable best efforts
to comply with all effective applicable provisions of the Sarbanes-Oxley Act. 
 8. Conditions to Cowen’s Obligations. The
obligations of Cowen 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 Cowen of a due diligence review satisfactory to Cowen in its reasonable judgment, and to the continuing satisfaction (or waiver by Cowen in its sole discretion) of the following additional conditions: 

(a) Registration Statement Effective. The Registration Statement (or a successor registration statement) shall be effective and
shall be available for (i) all sales of Placement Shares issued pursuant to all prior Placement Notices and (ii) the 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 or
any of its subsidiaries 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 

  
 - 19 - 

 
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, related Prospectus or such documents so that, in the case of the Registration Statement, it will not contain any materially 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 any materially 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. Cowen 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 Cowen’s reasonable opinion is material, or omits to state a fact that in Cowen’s 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, on a consolidated basis, in the authorized capital stock of the Company or any Material Adverse Change or any development that
could reasonably be expected to result in a Material Adverse Change, or any 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 Cowen (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) Company Counsel Legal Opinion. Cowen shall have received
the opinion of Company Counsel required to be delivered pursuant to Section 7(n) on or before the date on which such delivery of such opinion is required pursuant to Section 7(n). 

(f) Company Nevada Counsel Legal Opinions. Cowen shall have received the opinion of Company Nevada Counsel required to be
delivered pursuant to Section 7(n) on or before the date on which such delivery of such opinion is required pursuant to Section 7(n). 

(g) Cowen Counsel Legal Opinion. Cowen shall have received from Goodwin Procter LLP, counsel for Cowen, such opinion or opinions,
on or before the date on which the delivery of the Company Counsel Legal Opinion and Company Nevada Counsel Legal Opinion is required pursuant to Section 7(n), with respect to such matters as Cowen may reasonably require, and the Company
shall have furnished to such counsel such documents as they request for enabling them to pass upon such matters. 

  
 - 20 - 

 (h) Comfort Letter. Cowen shall have received the Comfort Letter required to be
delivered pursuant to Section 7(o) on or before the date on which such delivery of such Comfort Letter is required pursuant to Section 7(o). 

(i) Representation Certificate. Cowen shall have received the certificate required to be delivered pursuant to
Section 7(m) on or before the date on which delivery of such certificate is required pursuant to Section 7(m). 

(j) Secretary’s Certificate. On or prior to the First Delivery Date, Cowen shall have received a certificate, signed on
behalf of the Company by its corporate Secretary, in form and substance satisfactory to Cowen and its counsel. 
 (k) No
Suspension. Trading in the Common Stock shall not have been suspended on Nasdaq. 
 (l) Other Materials. On each date on
which the Company is required to deliver a certificate pursuant to Section 7(m), the Company shall have furnished to Cowen such appropriate further information, certificates and documents as Cowen may have reasonably requested. All such
opinions, certificates, letters and other documents shall have been in compliance with the provisions hereof. The Company will furnish Cowen with such conformed copies of such opinions, certificates, letters and other documents as Cowen shall have
reasonably requested. 
 (m) 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. 

(n) Approval for Listing. The Placement Shares shall either have been (i) approved for listing on Nasdaq, subject only to
notice of issuance, or (ii) the Company shall have filed an application for listing of the Placement Shares on Nasdaq at, or prior to, the issuance of any Placement Notice. 

(o) No Termination Event. There shall not have occurred any event that would permit Cowen to terminate this Agreement pursuant to
Section 11(a). 
 9. Indemnification and Contribution. 

(a) Company Indemnification. The Company agrees to indemnify and hold harmless Cowen, the directors, officers, partners, employees
and agents of Cowen and each person, if any, who (i) controls Cowen within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or (ii) is controlled by or is under common control with Cowen (a
“Cowen Affiliate”) from and against any and all losses, claims, liabilities, expenses and damages (including, but not limited to, any and all reasonable investigative, legal and other expenses incurred in connection with, and
any and all amounts paid in settlement (in accordance with Section 9(c)) of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or
otherwise, or any claim asserted), as and when incurred, to which Cowen, or any such person, may become subject 

  
 - 21 - 

 
under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages
arise out of or are based, directly or indirectly, on (x) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus or any amendment or supplement to the Registration Statement
or the Prospectus or in any free writing prospectus or in any application or other document executed by or on behalf of the Company in connection with this Agreement or based on written information furnished by or on behalf of the Company filed in
any jurisdiction in order to qualify the Common Stock under the securities laws thereof or filed with the Commission, or (y) the omission or alleged omission to state in any such document a material fact required to be stated in it or necessary
to make the statements in it not misleading in light of (other than in the case of the Registration Statement) the circumstances under which they were made; provided, however, that this indemnity agreement shall not apply to the extent
that such loss, claim, liability, expense or damage arises from the sale of the Placement Shares pursuant to this Agreement and is caused directly or indirectly by an untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with the Agent’s Information. This indemnity agreement will be in addition to any liability that the Company might otherwise have. 

(b) Cowen Indemnification. Cowen agrees to indemnify and hold harmless the Company and its directors and each officer of the
Company that signed the Registration Statement, and each person, if any, who (i) controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act or (ii) is controlled by or is under
common control with the Company (a “Company Affiliate”) against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 9(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) or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the
Agent’s Information. 
 (c) Procedure. Any party that proposes to assert the right to be indemnified under this
Section 9 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 9, notify each such
indemnifying party in writing of the commencement of such action, enclosing a copy of all papers served, but the failure 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 9 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 9 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 legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in 

  
 - 22 - 

 
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 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 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 as they are incurred. 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 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 9 (whether or not any indemnified party is a party
thereto), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding. 

(d) 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 9 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or Cowen, the Company and Cowen 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, but after deducting any
contribution received by the Company from persons other than Cowen, such as persons who control the Company within the meaning of the Securities Act, officers of the Company who signed the Registration Statement and directors of the Company, who
also may be liable for contribution) to which the Company and Cowen may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and Cowen on the other. The relative benefits
received by the Company on the one hand and Cowen 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 Cowen 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 Cowen, on the other, 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 

  
 - 23 - 

 
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 Cowen, 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 Cowen agree that it would not be just and equitable if contributions pursuant to this Section 9(d) 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 9(d) shall be deemed to include, for the purpose of this Section 9(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim
to the extent consistent with Section 9(c) hereof. Notwithstanding the foregoing provisions of this Section 9(d), Cowen shall not be required to contribute any amount in excess of the commissions received by it 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 9(d), any person who controls a party to this Agreement within the meaning of the Securities Act, and any officers, directors, partners, employees or agents of Cowen, will have the same rights to contribution as
that party, 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 9(d), 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 9(d) 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 9(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 9(c) hereof. 

10. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in
Section 9 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 Cowen, any controlling persons, or the Company (or any of their respective officers, directors or controlling persons), (ii) delivery and acceptance of the Placement Shares and payment therefor or (iii) any termination of this
Agreement. 
 11. Termination. 

(a) Cowen shall have the right by giving written notice as hereinafter specified at any time to terminate this Agreement if (i) any
Material Adverse Change, or any development that could reasonably be expected to result in a Material Adverse Change has occurred that, in the reasonable judgment of Cowen, may materially impair the ability of Cowen to sell the Placement Shares
hereunder, (ii) the Company shall have failed, refused or been unable to perform any 

  
 - 24 - 

 
agreement on its part to be performed hereunder; provided, however, in the case of any failure of the Company to deliver (or cause another person to deliver) any certification, opinion, or
letter required under Sections 7(m), 7(n), or 7(o), Cowen’s right to terminate shall not arise unless such failure to deliver (or cause to be delivered) continues for more than thirty (30) days from the date such
delivery was required, (iii) any other condition of Cowen’s obligations hereunder is not fulfilled, or (iv), any suspension or limitation of trading in the Placement Shares or in securities generally on Nasdaq shall have occurred. Any such
termination shall be without liability of any party to any other party except that the provisions of Section 7(g), Section 9, Section 10, Section 16 and Section 17 hereof shall remain in
full force and effect notwithstanding such termination. If Cowen elects to terminate this Agreement as provided in this Section 11(a), Cowen shall provide the required notice as specified in Section 12. 

(b) The Company shall have the right, by giving ten (10) days’ written 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 7(g), Section 9,
Section 10, Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination. 

(c) Cowen shall have the right, by giving ten (10) days’ written 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 7(g), Section 9, Section 10,
Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination. 

(d) Unless earlier terminated pursuant to this Section 11, this Agreement shall automatically terminate upon the issuance and
sale of all of the Placement Shares through Cowen on the terms and subject to the conditions set forth herein; provided that the provisions of Section 7(g), Section 9, Section 10, Section 16 and
Section 17 hereof shall remain in full force and effect notwithstanding such termination. 
 (e) This Agreement shall
remain in full force and effect unless terminated pursuant to Sections 11(a), (b), (c), or (d) above 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 7(g), Section 9, Section 10, Section 16 and Section 17 shall remain in full force and effect. 

(f) 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 Cowen 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. 
 12. Notices. All notices or
other communications required or permitted to be given by any party to any other party pursuant to the terms of this Agreement shall be in writing, unless otherwise specified in this Agreement, and if sent to Cowen, shall be delivered to Cowen at
