their business and are otherwise in compliance with all laws, rules and regulations applicable to them and their business, in each case now being conducted by them and as currently proposed to be conducted as disclosed in the SEC Documents, except
for such franchise, permit, license or similar authority, the lack of which, or which compliance failure, would not reasonably be expected to have a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any actual
notice of any proceeding relating to revocation or modification of any such franchise, permit, license, or similar authority except where such revocation or modification would not reasonably be expected to have a Material Adverse Effect. 

2.6 SEC Documents, Financial Statements. The Company has timely filed all reports, schedules, forms, statements and other documents
required to be filed by it with the SEC since January 1, 2014, pursuant to the reporting requirements of the Exchange Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements and
schedules thereto and documents (other than exhibits) incorporated by reference therein, being hereinafter referred to herein as the “SEC Documents”). Except as otherwise expressly stated herein, all references in this
Agreement to information disclosed or described in the SEC Documents shall include the disclosure set forth on Exhibit C hereto to the extent such disclosure is filed with the SEC on a Form 8-K on or before 9:30 a.m., New York local time, on
September 10, 2015. The Company is eligible to register its Common Stock for resale using Form S-3 promulgated under the Securities Act as of the date of this Agreement. The Company has delivered to each Purchaser, or each Purchaser has had
access to, true and complete copies of the SEC Documents. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the Exchange Act or the Securities Act, as the case may be, and the rules and
regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. As of their respective dates, the Financial Statements and the related notes complied as to form in all
material respects with applicable accounting requirements and the published rules and regulations of the SEC with 

  
 3 

 
respect thereto. The Financial Statements and the related notes have been prepared in accordance with accounting principles generally accepted in the United States, consistently applied,
during the periods involved (except (i) as may be otherwise indicated in the Financial Statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes, may be condensed or
summary statements or may conform to the SEC’s rules and instructions for Reports on Form 10-Q) and fairly present in all material respects the consolidated financial position of the Company as of the dates thereof and the consolidated results
of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal and recurring year-end audit adjustments). All material agreements that were required to be filed as exhibits to the SEC Documents
under Item 601 of Regulation S-K (collectively, the “Material Agreements”) to which the Company or any Subsidiary of the Company is a party, or the property or assets of the Company or any Subsidiary of the Company are
subject, have been filed as exhibits to the SEC Documents. All Material Agreements are valid and enforceable against the Company in accordance with their respective terms, except (i) as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, or moratorium or similar laws affecting creditors’ and contracting parties’ rights generally, and (ii) as enforceability may be subject to general principles of equity and except as rights to indemnity and
contribution may be limited by state or federal securities laws or public policy underlying such laws. The Company is not in breach of or default under any of the Material Agreements, and to the Company’s knowledge, no other party to a Material
Agreement is in breach of or default under such Material Agreement, except in each case, for such breaches or defaults as would not reasonably be expected to have a Material Adverse Effect. The Company has not received a notice of termination nor is
the Company otherwise aware of any threats to terminate any of the Material Agreements. 
 2.7 Disclosure Controls and
Procedures. Except as disclosed in the SEC Documents, the Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) that are effective in all material respects to ensure
that material information relating to the Company and its subsidiaries, including any consolidated subsidiaries, is made known to its chief executive officer and chief financial officer by others within those entities. The Company’s certifying
officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the most recently filed quarterly or annual periodic report under the Exchange Act (such date, the
“Evaluation Date”). The Company presented in its most recently filed quarterly or annual periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and
procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rules
13a-15(f) and 15d-15(f)) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal control over financial reporting. 

2.8 Accounting Controls. Except as disclosed in the SEC Documents, the Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles as applied in the United States 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. 

2.9 Absence of Litigation. Except as disclosed in the SEC Documents, as of the date hereof, there is no action, suit, proceeding or
investigation before or by any court, public board, government agency, self-regulatory organization or body pending or, to the Company’s knowledge, threatened against the Company or any of its subsidiaries, or any current or former director or
officer of the Company, that if determined adversely to the Company or any of its subsidiaries or current or former directors or officers would reasonably be expected to have a Material Adverse Effect or would reasonably be expected to impair the
ability of the Company to perform its obligations under this Agreement. Neither the Company, nor any director or officer thereof, nor any of its subsidiaries, is or has been the subject of any action involving a claim of violation of or liability
under federal or state securities laws or a claim of breach of fiduciary duty relating to the Company. The Company has not received any stop order or other order suspending the effectiveness of any registration statement filed by the Company under
the Exchange Act or the Securities Act and, to the Company’s knowledge, the SEC has not issued any such order.

 2.10 Intellectual Property Rights. The Company and its subsidiaries own, possess or can
acquire on reasonable terms sufficient trademarks, trademark applications, service marks, service names, trade names, patents, patent applications, patent rights, inventions, know-how, copyrights, domain names, licenses, approvals, trade secrets and
other similar rights reasonably necessary to conduct their businesses as now conducted and, to the knowledge of the Company, as proposed to be conducted as described in the SEC Documents (the “Intellectual Property”); except
to the extent failure to own, possess or acquire such Intellectual Property would not result in a Material Adverse Effect. To the Company’s knowledge, neither the Company nor any of its subsidiaries has infringed the intellectual property
rights of third parties and no third party, to the Company’s knowledge, is infringing the Intellectual Property, in each case, which could reasonably be expected to result in a Material Adverse Effect. Except as disclosed in the SEC Documents,
there are no material options, licenses or agreements relating to the Intellectual Property, nor is the Company, nor any subsidiary, bound by or a party to any material options, licenses or agreements relating to the patents, patent applications,
patent rights, inventions, know-how, trade secrets, trademarks, trademark applications, service marks, service names, trade names or copyrights of any other person or entity. Except as described in the SEC Documents, there is no material claim or
action or proceeding pending or, to the Company’s knowledge, threatened that challenges any of the rights of the Company or any subsidiary in or to, or otherwise with respect to, any Intellectual Property.

placement agent’s fees or similar payments relating to this Agreement or the transactions contemplated hereby. 
 2.12 Investment
Company. The Company is not and, after giving effect to the offering and sale of the Securities, will not be an “investment company” as such term is defined in the Investment Company Act of 1940, as amended (the “Investment

calamity, whether or not covered by insurance, or from any labor disturbance or dispute or any action, order or decree of any court or arbitrator or governmental or regulatory authority, and (iv) neither the Company nor any of its subsidiaries
has incurred any material liabilities except in the ordinary course of business.

terminate the registration of the Common Stock under the Exchange Act or remove from listing the Common Stock from Nasdaq, nor has the Company received any written notification that the SEC, Nasdaq or the Financial Industry Regulatory Authority,
Inc. is contemplating terminating such registration or quotation.

Purchaser or any of their respective representatives or agents to the Company in connection with this Agreement and the transactions contemplated hereby is merely incidental to such Purchaser’s purchase of the Securities. The Company further
represents to each Purchaser that the Company’s decision to enter into this Agreement has been based on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

responsibility against such losses and risks and in such amounts as the Company believes are prudent and customary for a company (i) in the businesses and location in which the Company and its subsidiaries are engaged, (ii) with the
resources of the Company, and (iii) at a similar stage of development as the Company and its subsidiaries. Neither the Company nor any of its subsidiaries have received any written notice that the Company or any subsidiary will not be able to
renew its existing insurance coverage as and when such coverage expires. The Company believes it will be able to obtain similar coverage at reasonable cost from similar insurers as may be necessary to continue its business. 

2.18 Foreign Corrupt Practices. Neither the Company or any of its subsidiaries, nor to the Company’s knowledge, any director,
officer, agent, employee or other Person acting on behalf of the Company or any of its subsidiaries is aware of or has, in the course of its actions for, or on behalf of, the Company or any of its subsidiaries (i) used any corporate funds for

have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith, except for the lack of which compliance, policies and procedures would not reasonably
be expected to have a Material Adverse Effect. 
 2.19 Private Placement. Neither the Company nor any of its subsidiaries or any
affiliates, nor any Person acting on its or their behalf, has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under any circumstances that would require registration of the Securities
under the Securities Act. Assuming the accuracy of the representations and warranties of the Purchasers contained in Article 3 hereof, the issuance of the Securities and the Warrant Shares are exempt from registration under the Securities Act.

(ii) other than as disclosed in the SEC Documents, require the Company to register any securities for sale under the Securities Act by reason of the filing of a Registration Statement except in the case of clause (ii) for rights which have
been properly waived. The granting and performance of the registration rights under this Agreement will not violate or conflict with, or result in a breach of any provision of, or constitute a default under, any agreement, indenture, or instrument
to which the Company is a party. 
 2.21 Taxes. The Company and its subsidiaries have filed (or have obtained an extension of time
within which to file) all necessary federal, state and foreign income and franchise tax returns and have paid all taxes required to be paid by them, except where the failure to so file or the failure to so pay would not reasonably be expected to

taken all necessary action, if any, in order to render inapplicable any control share acquisition law, business combination law, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the
Company’s charter or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their respective obligations or exercising their respective rights under
this Agreement, including, without limitation, as a result of the Company’s issuance of the Securities and Warrant Shares and the Purchasers’ acquisition and ownership of the Securities and Warrant Shares. 

2.24 No Manipulation of Stock. The Company has not taken, nor will it take, directly or indirectly any action designed to stabilize or
manipulate the price of the Common Stock or any security of the Company to facilitate the sale or resale of any of the Shares.

present view toward the public sale or distribution thereof and has no intention of selling or distributing any of such Securities or any arrangement or understanding with any other Persons regarding the sale or distribution of such Securities
except in accordance with the provisions of Article 6 and except as would not result in a violation of the Securities Act. The Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers

offered and sold to it in reliance upon specific exemptions from the registration requirements of United States federal and state securities laws. 

  
 7 

 3.2 Information. The Purchaser is not aware of any relevant materials relating to the
business, finances and operations of the Company necessary to make an investment decision, or materials relating to the offer and sale of the Securities, that have been requested by the Purchaser and have not been furnished to it, including, without
limitation, the Company’s SEC Documents, and the Purchaser has had the opportunity to review the SEC Documents. The Purchaser has been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other investigation
conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend or affect such Purchaser’s right to rely on the truth, accuracy and completeness of the SEC Documents and the Company’s representations and
warranties contained in the Agreement. 
 3.3 Acknowledgement of Risk. 

(a) The Purchaser acknowledges and understands that its investment in the Securities involves a significant degree of risk, including,
without limitation, (i) the Company remains a development stage business with limited operating history and requires substantial funds in addition to the proceeds from the sale of the Securities; (ii) an investment in the Company is
speculative, and only Purchasers who can afford the loss of their entire investment should consider investing in the Company and the Securities; (iii) the Purchaser may not be able to liquidate its investment; (iv) transferability of the
Securities is extremely limited; (v) in the event of a disposition of the Securities, the Purchaser could sustain the loss of its entire investment; and (vi) the Company has not paid any dividends on its Common Stock since inception and
does not anticipate the payment of dividends in the foreseeable future. Such risks are more fully set forth in the SEC Documents; 

(b) The Purchaser is able to bear the economic risk of holding the Securities for an indefinite period, and has knowledge and
experience in financial and business matters such that it is capable of evaluating the risks of the investment in the Securities; and

other information (whether oral or written) other than as set forth in the representations and warranties of the Company contained herein and the information disclosed in the SEC Documents, and the Purchaser has, with respect to all matters relating
to this Agreement and the offer and sale of the Securities, has not relied upon or consulted any counsel to the Company.

 3.5 Transfer or Resale. The Purchaser understands that: 

(a) the Securities and the Warrant Shares have not been and are not being registered under the Securities Act (other than as
contemplated in Article 6) or any applicable state securities laws and, consequently, the Purchaser may have to bear the risk of owning the Securities and the Warrant Shares for an indefinite period of time because the Securities and the Warrant
Shares may not be transferred unless (i) the resale of the Securities and the Warrant Shares, as applicable, is registered pursuant to an effective registration statement under the Securities Act; (ii) the Purchaser has delivered to the
Company an opinion of counsel (in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the Securities and the Warrant Shares to be sold or transferred may be sold or transferred pursuant to an
exemption from the registration requirements of the Securities Act; (iii) the Securities and the Warrant Shares are sold or transferred pursuant to Rule 144; or (iv) the Securities and the Warrant Shares are transferred without
consideration to its Affiliates or a custodial nominee; 

  
 8 

 (b) any sale of the Securities and the Warrant Shares made in reliance on Rule 144 may be
made only in accordance with the terms of Rule 144 and, if Rule 144 is not applicable, any resale of the Securities and the Warrant Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder; and 

(c) except as set forth in Article 6, neither the Company nor any other Person is under any obligation to register the resale of the
Shares or the Warrant Shares under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.

such Securities and Warrant Shares): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER APPLICABLE SECURITIES LAWS, OR UNLESS OFFERED, SOLD, PLEDGED, HYPOTHECATED OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS. THE COMPANY SHALL BE ENTITLED TO REQUIRE AN OPINION OF COUNSEL
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED TO THE EXTENT THAT SUCH OPINION IS REQUIRED PURSUANT TO THAT CERTAIN SECURITIES PURCHASE AGREEMENT UNDER WHICH THE SECURITIES WERE ISSUED. 

(b) To the extent the resale of the Shares or Warrant Shares is registered under the Securities Act pursuant to an effective
Registration Statement, the Company agrees to promptly (i) authorize the removal of the legend set forth in Section 3.6(a) and any other legend not required by applicable law from such Shares or Warrant Shares and (ii) cause its
transfer agent to issue such Shares or Warrant Shares without such legends to the holders thereof by electronic delivery at the applicable balance account at the Depository Trust Company upon surrender of any stock certificates evidencing such
Shares or Warrant Shares. With respect to any Shares or Warrant Shares for which restrictive legends are removed pursuant to this Section 3.6(b), the holder thereof agrees to only sell such Shares or Warrant Shares when and as permitted by the
effective Registration Statement covering such resale and in accordance with applicable securities laws and regulations. Any fees (with respect to the Company’s transfer agent, counsel or otherwise) associated with the removal of such legend(s)
shall be borne by the Company. The Purchaser hereby covenants and agrees that to the extent resales of the Shares or Warrant Shares are made pursuant to such effective Registration Statement, that such resales will be made only during the time that
such Registration Statement is effective and not withdrawn or suspended and only as permitted by such Registration Statement, and otherwise in compliance with the Securities Act (including applicable prospectus delivery obligations). 

  
 9 

 (c) The Purchaser may request that the Company remove, and the Company agrees to
authorize the removal of any legend from the Shares or Warrant Shares (i) following any sale of such Shares or Warrant Shares pursuant to Rule 144, (ii) if such Shares or Warrant Shares are eligible for sale under Rule 144 following the
expiration of the one year holding requirement under subparagraph (b)(1)(i) thereof, or (iii) if such Shares or Warrant Shares are sold under Rule 144 following the expiration of the six month holding requirement under subparagraph (d)(1)(i)
thereof provided that the Company maintains adequate current public information available pursuant to subparagraph (c)(1)(i) thereof. Following the time a legend is no longer required for the Shares or Warrant Shares under this Section 3.6(c),
the Company will, no later than three Business Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such securities, along with (a) if such request is made
pursuant to 3.6(c)(ii) or (iii), written confirmation by the Purchaser that it is not, and has not for the 3 months prior to the date of the request been, an affiliate within the meaning of Rule 144, or (b) if the confirmation in (a) is
not provided or, if such request is made pursuant to 3.6(c)(i), customary documentation related to the Purchaser, the transferee and the transaction for a transfer pursuant to Rule 144 required by the Company’s counsel to provide its opinion to
the transfer agent relating to the removal of the legends, (A) deliver or cause to be delivered to such Purchaser a certificate representing such Securities or Warrant Shares, as applicable, that is free from all restrictive and other legends
or (B) cause the Company’s transfer agent to credit the Purchaser’s or its designee’s account at DTC through its Deposit/Withdrawal at Custodian (DWAC) system with a number of shares of Common Stock equal to the number of
Securities or Warrant Shares, as applicable, represented by the certificate so delivered by the Purchaser (the date by which such certificate is required to be delivered to the Purchaser or such credit is so required to be made to the account of the
Purchaser or its designee at DTC pursuant to the foregoing is referred to herein as the “Required Delivery Date”). If the Company fails on or prior to the Required Delivery Date to either (i) issue and deliver (or
cause to be issued and delivered) to the Purchaser a certificate representing the Shares or Warrant Shares, as applicable, that is free from all restrictive and other legends or (ii) cause the Company’s transfer agent to credit the balance
account of the Purchaser or its designee at DTC through its Deposit/Withdrawal at Custodian (DWAC) system with a number of shares of Common Stock equal to the number of Shares or Warrant Shares, as applicable, represented by the certificate
delivered by the Purchaser pursuant hereto, then, in addition to all other remedies available to the Purchaser, the Company shall pay in cash to the Purchaser on each day after the Required Delivery Date that the issuance or credit of such shares is
not timely effected an amount equal to 1.0% of the product of (A) the sum of the number of Shares not issued to the Purchaser on a timely basis and to which the Purchaser is entitled and (B) the VWAP for the five Business Day period
immediately preceding the Required Delivery Date. In addition to the foregoing, if the Company fails to so properly deliver such unlegended certificate or so properly credit the account of the Purchaser or its designee at DTC by the Required
Delivery Date, and if on or after the Required Delivery Date the Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Purchaser of shares of Common Stock that the
Purchaser anticipated receiving from the Company without any restrictive legend, then the Company shall, within three Business Days after the Purchaser’s request, promptly honor its obligation to deliver to the Purchaser such unlegended
certificate or so properly credit the account of the Purchaser or its designee at DTC and pay cash to the Purchaser in an amount equal to the excess (if any) of the total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased by the Purchaser over the product of (A) the number of Shares or Warrant Shares that the Company was required to deliver to the Purchaser at the Required Delivery Date, times (B) the price at which the sell order
giving rise to such purchase obligation was executed. 
 3.7 Authorization; Enforcement. The Purchaser has the requisite power and
authority to enter into this Agreement and to consummate the transactions contemplated hereby. The Purchaser has taken all necessary action to authorize the execution, delivery and performance of this Agreement. Upon the execution and delivery of
this Agreement, this Agreement shall constitute a valid and binding obligation of the Purchaser enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal
securities laws or public policy underlying such laws. 
 3.8 Residency. Unless Purchase has otherwise notified the Company in
writing, the Purchaser is a resident of the jurisdiction set forth immediately below such Purchaser’s name on the signature pages hereto. 

3.9 Purchaser Status. At the time such Purchaser was offered the Shares and Warrants, it was, and at the date hereof it is, an
“accredited investor” as defined in Rule 501(a) of the Securities Act. 
 ARTICLE 4 

COVENANTS

Reporting Status. The Company’s Common Stock is registered under Section 12 of the Exchange Act. During the Registration Period, the Company will timely file all documents with the SEC, and the Company will not terminate its status as
an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. 

  
 10 

 4.2 Expenses. The Company shall pay the fees and expenses of Ropes & Gray LLP,
the counsel for the Purchasers, in an amount not to exceed $70,000. An estimate of the fees and expenses of Ropes & Gray LLP may be paid by check delivered or wire transfer to such counsel at the Closing by any Purchaser, the amount of such
check or wire transfer being deducted from the aggregate amount to be delivered by such Purchaser at the Closing for the securities to be purchased by it hereunder. 

4.3 Financial Information. The financial statements of the Company to be included in any documents filed with the SEC will be prepared
in accordance with accounting principles generally accepted in the United States, consistently applied (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes, may be condensed or summary statements or may conform to the SEC’s rules and instructions for Reports on Form 10-Q), and will fairly present in all material respects the consolidated
financial position of the Company and consolidated results of its operations and cash flows as of, and for the periods covered by, such financial statements (subject, in the case of unaudited statements, to normal and recurring year-end audit
adjustments). 
 4.4 Securities Laws Disclosure; Publicity. On or before 9:00 a.m., New York local time, on the date hereof,
the Company shall issue a press release announcing the signing of this Agreement and describing the terms of the transactions contemplated by this Agreement. On or before September 10, 2015, the Company shall file a Current Report on Form 8-K
with the SEC describing the terms of the transactions contemplated by this Agreement and including as an exhibit to such Current Report on Form 8-K this Agreement, in the form required by the Exchange Act. From and after the issuance of the press
release and the filing of the Form 8-K referenced in Section 2.6, no Purchaser shall be in possession of any material, non-public information received from the Company or any of its officers, directors, employees or agents, that is not
disclosed in the press release or Form 8-K. The Company shall not otherwise publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the SEC (other than in a Registration Statement and any exhibits to
filings made in respect of this transaction in accordance with periodic filing requirements under the Exchange Act) or any regulatory agency, without the prior written consent of such Purchaser, except to the extent such disclosure is required by
law or regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure. 
 4.5 Sales by
Purchasers. Each Purchaser will sell any Securities and, if applicable, any Warrant Shares held by it that are sold under a Registration Statement in compliance with applicable prospectus delivery requirements, if any, or otherwise in compliance
with the requirements for an exemption from registration under the Securities Act and the rules and regulations promulgated thereunder. No Purchaser will make any sale, transfer or other disposition of the Securities or, if applicable, Warrant
Shares in violation of federal or state securities laws, such that would prohibit the Company from authorizing the removal of any legend from the Shares and Warrant Shares. 

4.6 Reservation of Common Stock. The Company shall reserve and keep available at all times during which the Warrants remain
exercisable, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Warrant Shares pursuant to this Agreement. 

4.7 Lock-Up. During the period beginning from the Closing Date and continuing to and including the date 150 days after the Closing Date
(the “Lock-Up Period”), each Purchaser will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or
warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereinafter acquired, owned
directly by such Purchaser (including holding as a custodian) or with respect to which such Purchaser has beneficial ownership within the rules and regulations of the SEC (collectively, “Lock-up Shares”). The foregoing
restriction is expressly agreed to preclude each Purchaser from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of such Purchaser’s Lock-up
Shares even if such Lock-up Shares would be disposed of by someone other than such Purchaser. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including
without limitation any put or call option) with respect to any of a Purchaser’s Lock-up Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Lock-up Shares. Each Purchaser also
agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of such Purchaser’s Lock-up Shares except in compliance with the foregoing restrictions.

 ARTICLE 6 

REGISTRATION RIGHTS 

6.1 As soon as reasonably practicable, but in no event later than 90 days after the Closing Date (the “Filing
Date”), the Company shall file a registration statement covering the resale of the Registrable Securities with the SEC for an offering to be made on a continuous basis pursuant to Rule 415, or if Rule 415 is not available for offers and
sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Holders of a majority of the Registrable Securities may reasonably specify (the “Initial Registration Statement”). The
Initial Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form) and the Company shall
effect the registration, qualifications or compliances (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable blue sky or other state
securities laws and appropriate compliance with applicable securities laws, requirements or regulations) as promptly as possible after the filing thereof, but in any event prior to the date which is 150 days after the Closing Date. For purposes of
clarification, any failure by the Company to file the Initial Registration Statement by the Filing Date or to effect such Registration Statement within such 150 days after the Closing Date shall not otherwise relieve the Company of its obligations
to file or effect the Initial Registration Statement as set forth above in this Section 6.1. In the event the SEC informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for
resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof, (ii) file amendments to the Initial Registration Statement as required by the SEC and/or
(iii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by
the SEC, on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale the Registrable Securities as a secondary offering; provided, however,
that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its reasonable efforts to advocate with the SEC for the registration of all of the Registrable Securities. In the event the Company amends the
Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (ii) or (iii) above, the Company will use its reasonable efforts to file with the SEC, as promptly as allowed by the SEC, one or more
registration statements on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale those Registrable Securities that were not registered for resale on
the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”). Notwithstanding any other provision of this Agreement and subject to the payment of damages in
Section 6.3, if the SEC limits the number of Registrable Securities permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the SEC for the registration of
all or a greater number of Registrable Securities), any required cutback of Registrable Securities shall be applied to the Purchasers pro rata 

  
 13 

 
in accordance with the number of such Registrable Securities sought to be included in such Registration Statement by reference to the amount of Registrable Securities set forth opposite such
Purchaser’s name on Exhibit A (and in the case of a subsequent transfer, the initial Purchaser’s transferee) relative to the aggregate amount of all Registrable Securities. 

6.2 All Registration Expenses incurred in connection with any registration, qualification, exemption or compliance pursuant to
Section 6.1 shall be borne by the Company. All Selling Expenses relating to the sale of securities registered by or on behalf of Holders shall be borne by such Holders pro rata on the basis of the number of securities so registered. 

6.3 The Company further agrees that, in the event that (i) the Initial Registration Statement has not been filed with the SEC
within 90 days after the Closing Date, (ii) the Initial Registration Statement or the New Registration Statement, as applicable, has not been declared effective by the SEC within 150 days after the Closing Date, or (iii) after such
Registration Statement is declared effective by the SEC, is suspended by the Company or ceases to remain continuously effective as to all Registrable Securities for which it is required to be effective, other than, in each case, within the time
period(s) permitted by Section 6.7(b) (each such event referred to in clauses (i), (ii) and (iii), (a “Registration Default”)), for all or part of any thirty- (30) day period (a “Penalty
Period”) during which the Registration Default remains uncured (which initial thirty-day period shall commence on the third Business Day after the date of such Registration Default if such Registration Default has not been cured by such
date), the Company shall pay to each Purchaser 1.0% of such Purchaser’s Aggregate Purchase Price of his or her Securities for each Penalty Period during which the Registration Default remains uncured; provided, however, that in the event
that the Company’s failure to file or obtain the effectiveness of the Registration Statement on a timely basis results from the failure of a Purchaser to timely provide the Company with information requested by the Company and necessary to
complete the Registration Statement in accordance with the requirements of the Securities Act, then the commencement of the Penalty Period described above shall be extended without default or liquidated damages hereunder; and provided,
further, that in no event shall the Company be required hereunder to pay to any Purchaser pursuant to this Agreement more than 1.0% of such Purchaser’s Aggregate Purchase Price of his or her securities in any Penalty Period and in no event
shall the Company be required hereunder to pay to any Purchaser pursuant to this Agreement an aggregate amount that exceeds 10.0% of the Aggregate Purchase Price paid by such Purchaser for such Purchaser’s Securities. The Company shall deliver
said cash payment to the Purchaser by the fifth Business Day after the end of such Penalty Period. If the Company fails to pay said cash payment to the Purchasers in full by the fifth Business Day after the end of such Penalty Period, the Company
will pay interest thereon at a rate of 1.0% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Purchasers, accruing daily from the date such liquidated damages are due until such amounts, plus all
such interest thereon, are paid in full. Notwithstanding the foregoing, in the event a Registration Default occurs pursuant to clause (iii) hereof, the 1.0% of liquidated damages referred to above for any Penalty Period shall be reduced to
equal the percentage determined by multiplying 1.0% by a fraction, the numerator of which shall be the number of Registrable Securities covered by the Registration Statement that is suspended by the Company or ceases to remain continuously effective
as to all Registrable Securities for which it is required to be effective which are still Registrable Securities at such time and for which there is not otherwise an effective Registration Statement at such time and the denominator of which shall be
the number of Registrable Securities at such time. The parties agree that, notwithstanding anything to the contrary herein, no Liquidated Damages shall be payable with respect to any period after the expiration of the Registration Period (it being
understood that this sentence shall not relieve the Company of any liquidated damages accruing prior to the Registration Period). 
 6.4
In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform each Holder as to the status of such registration, qualification,
exemption and compliance. At its expense the Company shall: 
 (a) except for such times as the Company is permitted
hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company
determines to obtain, continuously effective with respect to a Holder, and to keep the applicable Registration Statement free of any material misstatements or omissions, until the earlier of the following: (i) the sixth anniversary of the
Closing Date or (ii) the date all Shares and, if applicable, Warrant Shares, held by or issuable to such Holder may be sold under Rule 144 without being subject to any volume, manner of sale or publicly available information requirements. The
period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period.” 

  
 14 

 (b) advise the Holders as promptly as practicable and in any event within five
(5) Business Days: 
 (i) when a Registration Statement or any amendment thereto has been filed with the SEC and when such
Registration Statement or any post-effective amendment thereto has become effective; 
 (ii) of any request by the SEC for
amendments or supplements to any Registration Statement or the prospectus included therein or for additional information; 

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any
proceedings for such purpose; 
 (iv) of the receipt by the Company of any notification with respect to the suspension of the
qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(v) of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of
such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they
were made) not misleading; 
 (c) use its commercially reasonable efforts to obtain the withdrawal of any order suspending
the effectiveness of any Registration Statement as soon as reasonably practicable; 
 (d) if a Holder so requests in writing,
promptly furnish to each such Holder, without charge, at least one copy of each Registration Statement and each post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form
filed with the SEC; 
 (e) during the Registration Period, promptly deliver to each such Holder, without charge, as many
copies of each prospectus included in a Registration Statement and any amendment or supplement thereto as such Holder may reasonably request in writing; and the Company consents to the use, consistent with the provisions hereof, of the prospectus or
any amendment or supplement thereto by each of the selling Holders of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by a prospectus or any amendment or supplement thereto; 

(f) during the Registration Period, if a Holder so requests in writing, deliver to each Holder, without charge, (i) one copy of
the following documents, other than those documents available via EDGAR: (A) its annual report to its stockholders, if any (which annual report shall contain financial statements audited in accordance with generally accepted accounting
principles in the United States of America by a firm of certified public accountants of recognized standing), (B) if not included in substance in its annual report to stockholders, its annual report on Form 10-K (or similar form), (C) its
definitive proxy statement with respect to its annual meeting of stockholders, (D) each of its quarterly reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report on Form 10-Q
(or similar form), and (E) a copy of each full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause
(E); 
 (g) prior to any public offering of Registrable Securities pursuant to any Registration Statement, promptly take such
actions as may be necessary to register or qualify or obtain an exemption for offer and sale under the securities or blue sky laws of such United States jurisdictions as any such Holders reasonably request in writing, provided that the Company shall
not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other
acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by any such Registration Statement; 

  
 15 

 (h) upon the occurrence of any event contemplated by Section 6.4(b)(v) above, except
for such times as the Company is permitted hereunder to suspend the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective
amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include
any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; 

(i) otherwise use its commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of
the SEC which could affect the sale of the Registrable Securities; 
 (j) use its commercially reasonable efforts to cause
all Registrable Securities to be listed on each securities exchange or market, if any, on which equity securities issued by the Company have been listed; 

(k) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities
contemplated hereby and to enable the Holders to sell Registrable Securities under Rule 144; 
 (l) provide to each Purchaser
and its representatives, if requested, the opportunity to conduct a reasonable inquiry of the Company’s financial and other records during normal business hours and make available its officers, directors and employees for questions regarding
information which such Purchaser may reasonably request in order to fulfill any due diligence obligation on its part; and 
 (m)
permit a single counsel for the Purchasers to review any Registration Statement and all amendments and supplements thereto (other than supplements to a Registration Statement on Form S-1 solely for the purpose of incorporating other filings with
the SEC into such Registration Statement and other than an amendment to a Registration Statement of Form S-1 on Form S-3 for the purpose of converting such Registration Statement into a Registration Statement on Form S-3), within two Business Days
prior to the filing thereof with the SEC; 
 provided that, in the case of clauses (l) and (m) above, the Company shall not be
required (A) to delay the filing of any Registration Statement or any amendment or supplement thereto as a result of any ongoing diligence inquiry by or on behalf of a Holder or to incorporate any comments to any Registration Statement or any
amendment or supplement thereto by or on behalf of a Holder if such inquiry or comments would require a delay in the filing of such Registration Statement, amendment or supplement, as the case may be, or (B) to provide, and shall not provide,
any Purchaser or its representatives with material, non-public information unless such Purchaser agrees to receive such information and enters into a written confidentiality agreement with the Company in a form reasonably acceptable to the Company.

 6.5 The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any registration pursuant to
Section 6.1 hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement. 

6.6 (a) To the extent permitted by law, the Company shall indemnify each Holder, each Holder’s directors, officers, employees and
agents and each Person controlling, or alleged to control by the Person making the claim, such Holder within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this
Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or
based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any such registration, qualification or compliance
or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were

  
 16 

 
made, or any violation or alleged violation by the Company of any rule or regulation, including without limitation the Securities Act and any rule or regulation promulgated under the Securities
Act in connection with any such registration, qualification or compliance, and will reimburse each Holder, each Holder’s officers, directors, employees and agents and each Person controlling, or alleged to control by the Person making the
claim, such Holder for reasonable legal and other out-of-pocket expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in
any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder expressly for use in preparation of
any Registration Statement, prospectus, amendment or supplement; provided further, (i) that the Company will not be liable in any such case to the extent the claim, loss, damage or liability arises out of the failure of such Holder to
comply with its covenants and agreements contained in this Agreement respecting sales of Registrable Securities, and (ii) insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in any
preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time any Registration Statement becomes effective or in an amended prospectus filed with the SEC pursuant to Rule 424(b) which meets the
requirements of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the benefit of any such Holder or any such controlling Person, if a copy of a Final Prospectus furnished
by the Company to the Holder for delivery a reasonable time prior to the relevant sale was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a
Final Prospectus would have eliminated any liability for such loss, liability, claim or damage. 
 (b) Each Holder will severally,
and not jointly, indemnify the Company, each of its directors, officers, employees and agents and each Person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities
(or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement)
of a material fact contained in any Registration Statement, prospectus, or any amendment or supplement thereof, incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors, officers, employees and agents, and each Person controlling the Company for
reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement
or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of and relating to the Holder expressly for use in preparation of any Registration Statement, prospectus,
amendment or supplement; provided that the indemnity shall not apply to the extent that such claim, loss, damage or liability results from the fact that a current copy of a prospectus was not made available to the Person asserting the loss,
liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, a
Holder’s aggregate liability pursuant to this subsection (b) and subsection (d) shall be limited to the net amount received by the Holder from the sale of the Registrable Securities. 

(c) Each party entitled to indemnification under this Section 6.6 (the “Indemnified
Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought,
and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An
Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Party, in its defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release
from all liability in respect to such claim or litigation. 

  
 17 

 (d) If the indemnification provided for in this Section 6.6 is held by a court of
competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall
contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the
Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and
of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or
by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. In no event shall the contribution obligation of a Holder together with any
indemnification obligation under this Section 6.6 be greater in amount than the dollar amount of the net received by it upon the sale of the Registrable Securities giving rise to such contribution obligation. 

6.7 (a) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of
a supplement or amendment to a prospectus relating to Registrable Securities so that, as thereafter delivered to the Holders, such prospectus shall 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, each Holder will forthwith use its best efforts to discontinue disposition of Registrable Securities pursuant to a Registration Statement and prospectus contemplated by
Section 6.1 until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such
Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 
 (b)
Each Holder shall use its best efforts to suspend, upon request of the Company, any disposition of Registrable Securities pursuant to any Registration Statement and prospectus contemplated by Section 6.1 during no more than two periods of
no more than 30 calendar days each during any 12-month period to the extent that the Board of Directors of the Company determines in good faith that the sale of Registrable Securities under any such Registration Statement would be reasonably likely
to cause a violation of the Securities Act or Exchange Act. 
 (c) As a condition to the inclusion of its Registrable Securities,
each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing as shall be necessary to complete the Registration Statement in accordance
with the requirements of the Securities Act in connection with any registration referred to in this Article 6. 
 (d) Each
Holder hereby covenants with the Company (i) not to make any sale of the Registrable Securities without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied, and (ii) if such Registrable
Securities are to be sold by any method or in any transaction other than on a national securities exchange or in the over-the-counter market, in privately negotiated transactions, or in a combination of such methods, to notify the Company at least
one Business Day prior to the date on which the Holder first offers to sell any such Registrable Securities. 
 (e) At the
end of the Registration Period the Holders shall discontinue sales of shares pursuant to any Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by any such Registration
Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company. 

6.8 With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which at any time permit
the sale of the Registrable Securities to the public without registration, so long as the Holders still own Registrable Securities, the Company shall use its reasonable best efforts to: 

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all
times; 

  
 18 

 (b) file with the SEC in a timely manner all reports and other documents required of the
Company under the Exchange Act; and 
 (c) so long as a Holder owns any Registrable Securities, furnish to such Holder, upon
any reasonable request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and
documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such securities without registration. 

6.9 The rights to cause the Company to register Registrable Securities granted to the Holders by the Company under Section 6.1 may
be assigned by a Holder in connection with a transfer by such Holder of all or a portion of its Registrable Securities, provided, however, that such Holder gives written notice to the Company thereof; and such transferee agrees to comply with
the terms and provisions of this Agreement applicable to a Holder, and such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 6.9, the rights of a Holder with respect to Registrable
Securities as set out herein shall not be transferable to any other Person, and any attempted transfer shall cause all rights of such Holder therein to be forfeited. 

6.10 Prior to the time that Registration Statement(s) covering the resale of all Registrable Securities have been
declared effective by the SEC, the Company shall not file with the SEC a registration statement under the Securities Act of any of its equity securities other than a registration statement required to be filed pursuant to this Agreement, a
registration statement on Form S-8 or, in connection with an acquisition, a registration statement on Form S-4; provided, however, that the foregoing restrictions in this Section 6.10 shall terminate upon such time as all of the
Registrable Securities (i) have been publicly sold by the Holders or (ii) may be sold under Rule 144 during any 90-day period. 

6.11 The rights of any Holder under any provision of this Article 6 may be waived (either generally or in a particular instance, either
retroactively or prospectively and either for a specified period of time or indefinitely) or amended by an instrument in writing signed by such Holder.

 Void After September 10, 2020 

THIS CERTIFIES THAT, for value received,             , with its principal
office at                 , or assigns (the “Holder”), is entitled to subscribe for and purchase at the Exercise Price (defined below) from
Orexigen Therapeutics, Inc., a Delaware corporation, with its principal office at 3344 N. Torrey Pines Ct., Suite 200, La Jolla California, 92037 (the “Company”) up to
                 shares of the Common Stock of the Company (the “Common Stock”), subject to adjustment as provided herein. This Warrant is one of
a series of Warrants being issued pursuant to the terms of the Securities Purchase Agreement, dated September 10, 2015, by and among the Company and the original Holder of this Warrant and the other parties named therein (the
“Purchase Agreement”). Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to such terms in the Purchase Agreement. 

1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings: 

(a) “Exercise Period” shall mean the period commencing on the date of issuance of this Warrant and ending

to the registered Holder at the address of the Holder appearing on the books of the Company) of (a) by email or facsimile, a duly executed notice of exercise (the “Notice of Exercise”) in substantially the form of the
Notice of Exercise Form annexed hereto and (b) the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer to:

which wire instructions may be amended by the Company by at least one Business Day’s prior written notice to the Holder, or cashier’s check drawn on
a United States bank unless the cashless exchange procedure specified in Section 2.2 below is specified in the applicable Notice of Exercise (the date on which such Notice of Exercise and Exercise Price (unless the cashless exchange procedure
specified in Section 2.2 below is specified in the applicable Notice of Exercise) is delivered to the Company (the “Date of Exercise”). In the case of a dispute between the Company and the Holder as to the calculation of
the Exercise Price or the number of Exercise Shares issuable hereunder (including, without limitation, the calculation of any adjustment pursuant to Section 3 below), the Company shall issue to the Holder the number of Exercise Shares that are
not disputed within the time periods specified below and shall submit the disputed calculations to a certified public accounting firm of national reputation (other than the Company’s regularly retained accountants) within three
(3) Business Days following the Company’s receipt of the Holder’s Notice of Exercise (such date, the “Warrant Share Delivery Date”). The Company shall cause such accountant to calculate the Exercise Price
and/or the number of Exercise Shares issuable hereunder and to notify the Company and the Holder of the results in writing no less than three (3) Business Days following the day on which such accountant received the disputed calculations. Such
accountant’s calculation shall be deemed conclusive absent manifest error. The fees of any such accountant shall be borne by the party whose calculations were most at variance with those of such accountant. Notwithstanding anything herein to
the contrary (although the Holder may surrender the Warrant to, and receive a replacement Warrant from, the Company), the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the
Exercise Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Business Days of the date the final Notice of Exercise is
delivered to the Company. The Company shall deliver any objection to any Notice of Exercise Form within one (1) Business Day of delivery of such notice. 

Certificates for shares (or, if the shares are represented in uncertificated form, comparable share notices reflecting such shares) purchased
hereunder shall be transmitted by the Transfer Agent (“Transfer Agent” means the transfer agent employed by the Company from time to time, for its Common Stock) to the Holder by crediting the account of the Holder’s
prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration
statement permitting the issuance of the Exercise Shares to or resale of the Exercise Shares by the Holder or (B) this Warrant is being exercised via cashless exchange and Rule 144 is available, and otherwise by physical delivery to the address
specified by the Holder in the Notice of Exercise by the date that is three (3) Business Days after the Date of Exercise. The Exercise Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein
shall be deemed to have become a holder of record of such shares for all purposes, as of the Date of Exercise. Notwithstanding anything herein to the contrary, the Company shall not be required to make any cash payments or net cash settlement to the
registered holder in lieu of issuance of the Exercise Shares, except as provided below. The Company understands that a delay in the delivery of the Exercise Shares after the Warrant Share Delivery Date could result in economic loss to the Holder. In
addition to any other rights available to the Holder, as compensation to the Holder for such loss, if (i) the Company fails to deliver the number of Exercise Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant
within the time periods specified above and (ii) the Holder has not exercised its Buy-In rights as provided below with respect to such shares, the Company agrees to pay (as liquidated damages and not as a penalty) to the Holder for late
issuance of Warrant Shares upon exercise of this Warrant the proportionate amount of $100 per Business Day after the Warrant Share Delivery Date for each $10,000 of Exercise Price of Exercise Shares for which this Warrant is exercised which are not
timely delivered. For purposes of clarification, if the Company is obligated to make payments of liquidated damages pursuant to this Section for late issuance of Exercise Shares, then it shall not also be obligated to make Buy-In payments as
described below with respect to those same Exercise Shares. The Company shall make any payments incurred under this Section in immediately available funds upon demand. 

 In addition to any other rights available to the Holder, if the Company fails for any reason to
effect delivery of the Exercise Shares to Holder by the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder or its brokerage firm otherwise
purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to
the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased, exceeds (y) the amount obtained by multiplying (1) the number of
Exercise Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the
Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common
Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an
attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The
Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue
any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares
of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof. 
 In the event that the Company fails for any reason
to effect delivery of the Exercise Shares to Holder by the Warrant Share Delivery Date, then Holder may, at any time prior to issuance of such Exercise Shares, revoke all or part of the relevant Warrant exercise by delivery of a notice to such
effect to the Company, whereupon the Company and the Holder shall each be restored to their respective positions immediately prior to the exercise of the relevant portion of this Warrant, except that the liquidated damages described above shall be
payable through the date notice of revocation is given to the Company. 
 Issuance of this Warrant and certificates for Exercise Shares
shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company; provided, however, that
the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Exercise Shares or Warrants in a name other than that of the Holder. The Company shall pay all
Transfer Agent fees required for processing of any Notice of Exercise. The Holder shall be responsible for all of its tax liability that may arise as a result of it holding or transferring this Warrant or receiving Exercise Shares upon exercise
hereof. 
 2.2 Cashless Exchange. Notwithstanding any provisions herein to the contrary, if, at any time during the Exercise Period,
the Current Market Price (as defined below) of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may exchange this Warrant
for shares in a cashless exchange by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise and the Company shall issue to the Holder a number of shares of Common Stock computed using
the following formula: 
  

							
		  		  	X =	  	 Y (B-A)

      B

					
			
	Where:	  	X =	  	the number of shares of Common Stock to be issued to the Holder.

			
	Y =	 	the number of shares of Common Stock purchasable upon exercise of all of the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised.
		
	A =	 	the Exercise Price.
		
	B =	 	the Current Market Price of one share of Common Stock plus the fair market value of any Distributed Property with respect to a share of Common Stock.

 The Company and Holder agree to treat an exchange pursuant to this Section 2.2 as a
“recapitalization” within the meaning of Section 368(a)(1)(E) of the Internal Revenue Code of 1986, as amended. 

“Current Market Price” means on any particular date: 

(a) if the Common Stock is traded on The Nasdaq Global Market or The Nasdaq Capital Market, the closing price of the Common Stock of
the Company on such market on the day prior to the applicable date of valuation; 
 (b) if the Common Stock is traded on any
registered national stock exchange but is not traded on The Nasdaq Global Market or The Nasdaq Capital Market, the closing price of the Common Stock of the Company on such exchange on the day prior to the applicable date of valuation; 

(c) if the Common Stock is traded over-the-counter, but not on The Nasdaq Global Market, The Nasdaq Capital Market or a registered
national stock exchange, the closing bid price of the Common Stock of the Company on the day prior to the applicable date of valuation; and 

(d) if there is no active public market for the Common Stock, the value thereof, as determined in good faith by the Board of Directors
of the Company upon due consideration of the proposed determination thereof by the Holder, as communicated to the Holder by the Company, provided that, the Holder may, if it disagrees with such value, in addition to any other rights it may have,
withdraw such request for a cashless exchange. 
 2.3 Partial Exercise. Partial exercises of this Warrant resulting in purchases of a
portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder
and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. In the case of a partial exercise of this Warrant, the Holder may request that the Company deliver to the Holder a certificate
representing such new warrant, with terms identical in all respects to this Warrant (except that such new warrant shall be exercisable into the number of shares of Common Stock with respect to which this Warrant shall remain unexercised); provided,
however, that the Holder shall be entitled to exercise all or any portion of such new warrant at any time following the time at which this Warrant is exercised, regardless of whether the Company has actually issued such new warrant or delivered to
the Holder a certificate thereof. In no event shall this Warrant be exercised for a fractional Exercise Share, and the Company shall not distribute a Warrant exercisable for a fractional Exercise Share. Fractional Warrant shares shall be treated as
provided in Section 6 hereof. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the exercise of a portion of this Warrant, the number of
Exercise Shares issuable upon exercise of this Warrant hereunder at any given time may be less than the amount stated on the face hereof. 

2.4 No Settlement for Cash. The Warrant cannot be settled with the Company for cash. 

2.5 Exercise Limitation. The Company shall not effect the exercise of this Warrant and the Holder shall not have the right to exercise
this Warrant, to the extent that after giving effect to such exercise, the Holder (together with the Holder’s affiliates) would beneficially own in excess of 19.99% (the “Maximum Percentage”) of the shares of Common
Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Holder and its affiliates shall include the number of shares of
Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be 

 
issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Holder and its affiliates and (ii) exercise or conversion of the unexercised
or unconverted portion of any other securities of the Company beneficially owned by such Holder and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on
conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in
(x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, filed with the SEC on the date thereof, (y) a more recent public announcement by the Company or (z) any other notice by the Company or its transfer agent
setting forth the number of shares of Common Stock outstanding. Upon the written request of the Holder, the Company shall within three Business Days confirm in writing or by electronic mail to the Holder the number of shares of Common Stock then
outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder since the date as of which such
number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 19.99% specified in such notice;
provided that (i) any such increase will not be effective until the sixty-fifth (65th) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder
of Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or
inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. Notwithstanding any of the limitations set forth in this paragraph,
this Warrant shall be fully exercisable in connection with a Liquidation Event (as defined below). In accordance with such listing standards, this restriction will apply at any time when the Warrant is outstanding, regardless of whether the Company
then has a class of securities listed on The NASDAQ Global Market. For purposes herein, “Liquidation Event” shall mean the consummation of any of the following transactions: (a) a merger or consolidation in which the Company is not
the surviving entity (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation or continuation of the Company in a different jurisdiction, or other transaction in which there is no substantial change in the shareholders
of the Company), (b) the sale of all or substantially all of the assets of the Company, or (c) the acquisition, sale or transfer of more than 50% of the outstanding shares of the Company by take-over bid or similar transaction. 

3. COVENANTS OF THE COMPANY. 
 3.1
Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be duly and validly authorized, issued and
outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized
reserved and available, free from preemptive rights, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but
unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common
Stock (or other securities as provided herein) to such number of shares as shall be sufficient for such purposes. 
 3.2 No
Impairment. Except and to the extent as waived or consented to by the Holder or otherwise in accordance with Section 11 hereof, the Company will not, by amendment of its Certificate of Incorporation (as such may be amended from time to
time), or through any means, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment. 

 3.3 Notices of Record Date. In the event of any taking by the Company of a record of the
holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarters) or other distribution, the
Company shall mail to the Holder, at least 10 days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution. 

3.5 Distributions. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its
assets) (the “Distributed Property”) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by
way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the
Holder shall be entitled, upon exercise of this Warrant for the purchase of any or all of the Exercise Shares, to receive the amount of Distributed Property which would have been payable to the Holder had such Holder been the holder of such Exercise
Shares on the record date for the determination of the stockholders entitled to receive such Distributed Property. The Company will at all times set aside in escrow and keep available for distribution to such Holder upon exercise of this
Warrant a portion of the Distributed Property to satisfy the distribution to which such Holder is entitled pursuant to the preceding sentence. 
 4.
[RESERVED] 
 5. ADJUSTMENT OF EXERCISE PRICE. In the event of changes in the outstanding Common Stock of the Company by reason of stock
dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, mergers, consolidations or the like, the number and class of shares available under the Warrant in the
aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been
exercised prior to the event and had the Holder continued to hold such shares until after the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number, class, and kind of shares subject to this
Warrant. The Company shall promptly provide a certificate from its Chief Financial Officer notifying the Holder in writing of any adjustment in the Exercise Price and/or the total number, class, and kind of shares issuable upon exercise of this
Warrant, which certificate shall specify the Exercise Price and number, class and kind of shares under this Warrant after giving effect to such adjustment. 

6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All
Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in
the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value
of an Exercise Share by such fraction. 
 7. CERTAIN EVENTS. In the event of, at any time during the Exercise Period, any capital reorganization, or
any reclassification of the capital stock of the Company (other than a change in par value or from par value to no par value or no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the
consolidation or merger of the Company with or into another corporation (other than a merger solely to effect a reincorporation of the Company into another state), in each case, in which the stockholders of the Company immediately prior to such
capital reorganization, reclassification, consolidation or merger, will hold less than a majority of the outstanding shares of the Company or resulting corporation immediately after such capital reorganization, reclassification, consolidation or
merger, or the sale or other disposition of all or substantially all of the properties and assets of the Company and its subsidiaries, taken as a whole, in its entirety to any other person, other than sales or other dispositions that do not require
stockholder approval (each, an “Event”), the Company shall provide to the Holder 10 days’ advance written notice of such Event, and the Holder shall have the option, in its sole discretion, to allow any unexercised
portion of the Warrant to be deemed automatically exercised pursuant to Section 2.2. This Warrant will be binding upon the successors and assigns of the Company upon an Event. 

 8. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not entitle the Holder to any voting rights
or other rights as a stockholder of the Company. 
 9. TRANSFER OF WARRANT. Subject to applicable laws and compliance with the Purchase Agreement,
this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. 

10. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to
indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such
new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. 

11. MODIFICATIONS AND WAIVER. This Warrant and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing
signed by the Company and (i) Purchasers holding Warrants representing at least 80% of the number of Exercise Shares then issuable upon exercise of the Warrants sold in the Offering, provided, however, that such modification, amendment
or waiver is made with respect to all Warrants issued in the Offering and does not adversely affect the Holder without adversely affecting all holders of Warrants in a similar manner; or (ii) the Holder. 

12. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal
delivery to the party to be notified, (b) when sent by confirmed email, telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five days after having been sent by registered or
certified mail, return receipt requested, postage prepaid, or (d) one business day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be
sent to the Company at the address listed on the signature page and to the Holders at the addresses on the Company records, or at such other address as the Company or Holder may designate by 10 days’ advance written notice to the other party
hereto. 
 13. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions
contained herein. 
 14. GOVERNING LAW. This Warrant and all rights, obligations and liabilities hereunder shall be governed by the laws of the State
of California without regard to the principles of conflict of laws. 
 15. DESCRIPTIVE HEADINGS. The descriptive headings of the several paragraphs
of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. The language in this Warrant shall be construed as to its fair meaning without regard to which party drafted this Warrant. 

16. SEVERABILITY. The invalidity or unenforceability of any provision of this Warrant in any jurisdiction shall not affect the validity or
enforceability of such provision in any other jurisdiction, or affect any other provision of this Warrant, which shall remain in full force and effect. 

17. ENTIRE AGREEMENT. This Warrant constitutes the entire agreement between the parties pertaining to the subject matter contained in it and supersedes
all prior and contemporaneous agreements, representations, and undertakings of the parties, whether oral or written, with respect to such subject matter.

LEGAL OPINIONEX-10.1

 Exhibit 10.1 

THIRD AMENDMENT TO LOAN AGREEMENT 

THIS THIRD AMENDMENT TO LOAN AGREEMENT (this “Third Amendment”), is made and entered into as of September 3, 2015, by
and among GLADSTONE LAND LIMITED PARTNERSHIP, a Delaware limited partnership (“Borrower”), GLADSTONE LAND CORPORATION, a Maryland corporation (“Guarantor”) and METROPOLITAN LIFE INSURANCE COMPANY, a New York
corporation (the “Lender”). 
 R E C I T A L S: 

A. Borrower, Guarantor and Lender are parties to that certain Loan Agreement dated as of April 30, 2014, as amended by that certain First
Amendment to Loan Agreement dated as of August 26, 2014, and as further amended by that certain Second Amendment to Loan Agreement dated as of October 29, 2014 (collectively, the “Loan Agreement”). The Loan Agreement was
executed in connection with a loan (the “Loan”) made by Lender to Borrower evidenced by those certain Notes dated April 30, 2014 payable to the order of Lender in the original aggregate principal amount of up to $125,000,000,
each as amended by a first amendment dated as of even date herewith (the “Notes”). The Notes are currently secured by the Security Instruments, as defined in the Loan Agreement (the “Existing Security Instruments”).
Guarantor has guaranteed the payment and performance of the Loan pursuant to that certain Loan Guaranty Agreement dated as of April 30, 2014 (the “Guaranty”). Capitalized terms used but not otherwise defined herein shall have
the meanings given to them in the Loan Agreement. 
 B. Borrower has requested to provide additional Collateral for the Loan, by adding
Future Property and a Future Property Owner under the terms of the Loan Agreement. 
 C. Borrower has requested that Bear Mountain Arvin,
LP, a Delaware limited partnership, be added as Property Owner, and the property owned by Bear Mountain Arvin, LP in Kern County, California be added as Land and Collateral (“Bear Mountain Arvin Property”) under the Loan as more
particularly described in Exhibit A-1. 
 D. Borrower has requested that Lender consent to certain modifications to the terms of the
Loan, including without limitation, the extension of the period during which Borrower may request Subsequent Disbursements. 
 E. The
parties enter into this Third Amendment to confirm the addition of the Additional Property as Collateral for the Loan and the Future Property Owner as Property Owner for the Loan, to provide for certain other terms relating to the addition of the
Additional Property and to further amend the Loan Agreement as provided for herein. Capitalized terms not otherwise defined herein shall have the meaning given in the Loan Agreement. 

NOW THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Borrower, Guarantor and Lender
hereby agree as follows: 
 1. Status of Existing Loan. Borrower and Guarantor acknowledge for the benefit of Lender that the Notes,
the Loan Agreement as amended by this Third Amendment, the Existing Security Instruments, and any other Loan Documents (collectively, the “Loan Documents”) are all valid and binding obligations enforceable in accordance with their
terms, and that neither Borrower nor the Guarantor has any offset or defense against the indebtedness evidenced by the Notes or any of the obligations set forth in the Loan Documents. 

  
 1 

 2. Addition of New Land. The definition of “Land” set forth in the Loan
Agreement is hereby amended to include the Additional Property. Exhibit A of the Loan Agreement is hereby amended to include the Additional Property as set forth in Exhibit A-1 hereof. All references in the Loan Agreement to the
Disclosure and Valuation Agreement shall hereafter mean the Disclosure and Valuation Agreement as amended by the First Amendment to Disclosure and Valuation Agreement dated August 26, 2014, as further amended by the Disclosure and Valuation
Agreement Second Amendment dated October 29, 2014, and as further amended by the Disclosure and Valuation Agreement Third Amendment dated as of even date herewith. Lender, Borrower and Guarantor agree and acknowledge that the Appraised Value of
the Additional Property included in the Disclosure and Valuation Third Amendment is based on the Borrower’s cost of acquisition of the Additional Property, with a third party appraisal to be provided to Lender within forty-five (45) days
of the Subsequent Disbursement performed by Randy Merriman, with Merriman Hurst & Associates, Inc. (the “Bear Mountain Appraisal”). Upon receipt of the Bear Mountain Appraisal, and Lender’s acceptance thereof, which shall not
be unreasonably conditioned, delayed or withheld, the Appraised Value reflected, as of that date, in the Disclosure and Valuation Third Amendment shall be updated to reflect the Bear Mountain Appraisal. 

(a) Upon the completion of the development of permanent plantings (the “Bear Mountain Development”), the Appraised Value of the Bear
Mountain Property will be subsequently increased if substantially consistent with the “as-built valuations” established in the Bear Mountain Appraisal, and as confirmed, in the exercise of its good faith discretion, by Lender upon
inspection of the condition and viability of plantings and related water infrastructure, and Lender’s confirmation that market conditions remain substantially consistent with those assumed in the appraisal, or confirmed by a separate third
party appraisal prepared by an appraiser approved by Lender. Lender will use its commercially reasonable efforts to complete any such inspection or appraisal within ten (10) days after Borrower’s written request. 

(b) In addition in connection with the Bear Mountain Development, Borrower shall have the ability to request up to four (4) additional
disbursements to fund (or reimburse Borrower for) the costs of the Bear Mountain Development (each such request a “Development Disbursement Request”). In connection with each Development Disbursement Request, Borrower shall submit
records of all costs incurred or contemplated in connection with the Development Disbursement Request (“Development Costs”) to Lender (such information to be submitted within five (5) days of each Development Disbursement
Request), and Lender will use its commercially reasonable efforts to complete an inspection of the Bear Mountain Property within ten (10) days after Borrower’s Development Disbursement Request. Upon Lender’s satisfactory inspection of
the condition and viability of plantings and related water infrastructure, and in no event later than ten (10) days following each Development Disbursement Request, the Appraised Value of the Bear Mountain Property will be increased by the
amount of the Development Costs and Lender shall disburse to Borrower an amount equal to fifty eight percent (58%) of the total Development Costs. Any such disbursement shall not be counted against Borrower’s maximum number of yearly
disbursements under to Section 3.1(b)(11) of the Loan Agreement. 
 3. Addition of New Property Owner. The definition of
“Property Owners” set forth in the Loan Agreement is hereby amended to include the New Property Owner. Accordingly, Exhibit B of the Loan Agreement is hereby amended to include the New Property Owner as set forth in Exhibit B-1
hereof. 
 4. New Security Instruments and Loan Documents. The New Property Owner shall execute and deliver to Lender, as a condition
to the effectiveness of this Third Amendment and Lender’s acceptance of the Additional Property, the following documents, each in substantially the form executed by the Existing Property Owners: 

(a) a new Security Instrument encumbering its interest in the Additional Property (the “New Security Instrument”);
