The parties hereby agree as follows: 

1. Certain Definitions.

Shares and (iv) any other securities issued or issuable with respect to or in exchange for Registrable Securities, whether by merger, charter amendment or otherwise; provided, that, a security shall cease to be a Registrable Security upon
(A) sale pursuant to a Registration Statement or Rule 144 under the 1933 Act, or (B) such security becoming eligible for sale without restriction by the Purchasers pursuant to Rule 144. 

“Registration Statement” means any registration statement of the Company filed under the 1933 Act that covers the resale

 “1934 Act” means the Securities Exchange Act of 1934, as amended, and
the rules and regulations promulgated thereunder. 
 2. Registration. 

(a) Registration Statements. Promptly following the closing of the purchase and sale of the securities contemplated by the
Purchase Agreement (the “Closing Date”) but no later than forty-five (45) days after the Closing Date (the “Filing Deadline”), the Company shall prepare and file with the SEC one Registration Statement on Form
S-3 (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available to effect a registration for resale of the Registrable Securities), covering the resale of the Registrable Securities. Subject to
any SEC comments, such Registration Statement shall include the plan of distribution attached hereto as Exhibit A; provided, however, that no Purchaser shall be named as an “underwriter” in the Registration Statement without the
Purchaser’s prior written consent. Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common
Stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. Such Registration Statement shall not include any shares of Common Stock or other securities for the account of any other holder
without the prior written consent of the Required Purchasers except with respect to security holders of the Company that possess registration rights granted by the Company prior to the date hereof. The Registration Statement (and each amendment or
supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Purchasers and their counsel prior to its filing or other submission. If a Registration Statement covering
the Registrable Securities is not filed with the SEC on or prior to the Filing Deadline, the Company will make pro rata payments to each Purchaser, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount
invested by such Purchaser for each 30-day period or pro rata for any portion thereof following the Filing Deadline for which no Registration Statement is filed with respect to the Registrable Securities. The filing of the Registration Statement
shall terminate the existence of any event giving rise to the payment of liquidated damages pursuant to the foregoing sentence. Such payments shall constitute the Purchasers’ exclusive monetary remedy for such events, but shall not affect the
right of the Purchasers to seek injunctive relief. Such payments shall be made to each Purchaser in cash no later than ten (10) days after the end of each 30-day period. 

(b) Expenses. The Company will pay all expenses associated with each registration, including filing and printing fees, the
Company’s counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws, and listing fees. In no event shall the Company be responsible for any discounts,
commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold, or any legal fees or other costs of the Holders. 

 

 -2- 

 (c) Effectiveness. 

(i) The Company shall use commercially reasonable efforts to have the Registration Statement declared effective as
soon as practicable. The Company shall notify the Purchasers by facsimile or e-mail as promptly as practicable, and in any event, within twenty-four (24) hours, after any Registration Statement is declared effective and shall simultaneously
provide the Purchasers with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby. If (A) a Registration Statement covering the Registrable Securities is not declared
effective by the SEC prior to the earlier of (i) five (5) Business Days after the SEC shall have informed the Company that no review of the Registration Statement will be made or that the SEC has no further comments on the Registration
Statement or (ii) the 90th day after the filing date,
or (B) after a Registration Statement has been declared effective by the SEC, sales cannot be made pursuant to such Registration Statement for any reason (including without limitation by reason of a stop order, or the Company’s failure to
update the Registration Statement), but excluding any Allowed Delay (as defined below) or the inability of any Purchaser to sell the Registrable Securities covered thereby due to market conditions, then the Company will make pro rata payments to
each Purchaser, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount invested by such Purchaser for each 30-day period or pro rata for any portion thereof following the date by which such Registration
Statement should have been effective (the “Blackout Period”). Such payments shall constitute the Purchasers’ exclusive monetary remedy for such events, but shall not affect the right of the Purchasers to seek injunctive relief.
The amounts payable as liquidated damages pursuant to this paragraph shall be paid monthly within ten (10) days of the last day of each month following the commencement of the Blackout Period until the termination of the Blackout Period. The
Blackout Period shall expire upon the declaration of effectiveness by the SEC of the Registration Statement (if the Blackout Period is covered by clause (A) of this Section 2(c)(i)) or the date on which sales pursuant to the Registration
Statement may resume (if the Blackout Period is covered by clause (B) of this Section 2(c)(i)). Such payments shall be made to each Purchaser in cash. 

(ii) For not more than twenty (20) consecutive days or for a total of not more than forty-five (45) days in any twelve
(12) month period, the Company may suspend the use of any Prospectus included in any Registration Statement contemplated by this Section in the event that the Company determines in good faith that such suspension is necessary to (A) delay
the disclosure of material non-public information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company or (B) amend or supplement the affected
Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the Company shall promptly (a) notify each Purchaser in writing of
the commencement of and the reasons for an Allowed Delay, but shall not (without the prior written consent of a Purchaser) disclose to such Purchaser any material non-public information giving rise to an Allowed Delay, (b) advise the Purchasers
in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable. 

 

 -3- 

 (d) Rule 415; Cutback If at any time the SEC takes the position
that the offering of some or all of the Registrable Securities in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the 1933 Act or requires any Purchaser to be named as an
“underwriter”, the Company shall use commercially reasonable efforts to persuade the SEC that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the
issuer” as defined in Rule 415 and that none of the Purchasers is an “underwriter”. The Purchasers shall have the right to participate or have their counsel participate in any meetings or discussions with the SEC regarding the
SEC’s position and to comment or have their counsel comment on any written submission made to the SEC with respect thereto. No such written submission shall be made to the SEC to which the Purchasers’ counsel reasonably objects. In the
event that, despite the Company’s commercially reasonable efforts and compliance with the terms of this Section 2(d), the SEC refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of
the Registrable Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s
compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Purchaser as an “underwriter” in such Registration Statement without the
prior written consent of such Purchaser. Any cut-back imposed on the Purchasers pursuant to this Section 2(d) shall be allocated among the Purchasers on a pro rata basis and shall be applied first to any Conversion Shares, unless the SEC
Restrictions otherwise require or provide or the Purchasers otherwise agree. No liquidated damages shall accrue as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with
any SEC Restrictions (such date, the “Restriction Termination Date”) of such Cut Back Shares. From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 2 (including
the liquidated damages provisions) shall again be applicable to such Cut Back Shares; provided, however, that (i) the Filing Deadline for the Registration Statement including such Cut Back Shares shall be thirty (30) days after such
Restriction Termination Date, and (ii) the date by which the Company is required to obtain effectiveness with respect to such Cut Back Shares under Section 2(c) shall be the
90th day immediately after the Restriction Termination
Date. 
 (e) If an event occurs resulting in the Company being required to make payments to a Purchaser pursuant to the
liquidated damages provisions of Section 2(a) or 2(c) (a “Registration Event”), the Company’s maximum liability under Section 2(a) and 2(c) shall be to make payments up to 6% of the aggregate amount invested by the
Purchasers; provided, however, if a Registration Event occurs (or is continuing) on a date more than six months after the Purchaser acquired the Registrable Securities (and thus the six month holding period under Rule 144(d) has
elapsed), liquidated damages shall be paid only with respect to that portion of the Purchaser’s Registrable Securities that cannot then be immediately resold in reliance on Rule 144. Further, amounts payable as liquidated damages to each
Purchaser hereunder with respect to each share of Registrable Securities shall cease when the Purchaser no longer holds such shares of Registrable Securities. No Registration Event shall be deemed to occur or continue if such Registration Event is
caused by delays which are solely attributable to (i) the failure of a Purchaser to timely advise the Company of any information regarding such Purchaser for inclusion in the Registration Statement, or (ii) the resolution of comments from
the SEC pertaining to the Purchasers. 
  

 -4- 

 3. Company Obligations. The Company will use commercially reasonable efforts to
effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as expeditiously as possible: 

(a) use commercially reasonable efforts to cause such Registration Statement to become effective and to remain continuously effective
for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, and (ii) the date on which all Registrable
Securities covered by such Registration Statement may be sold without restriction pursuant to Rule 144 (the “Effectiveness Period”) and advise the Purchasers in writing when the Effectiveness Period has expired; 

(b) prepare and file with the SEC such amendments and post-effective amendments to the Registration Statement and the Prospectus as may
be necessary to keep the Registration Statement effective for the Effectiveness Period and to comply with the provisions of the 1933 Act and the 1934 Act with respect to the distribution of all of the Registrable Securities covered thereby;

 (c) provide copies to and permit counsel designated by the Purchasers to review each Registration Statement and all
amendments and supplements thereto no fewer than five (5) days prior to their filing with the SEC and not file any document to which such counsel reasonably objects; 

(d) furnish to the Purchasers and their legal counsel (i) promptly after the same is prepared and publicly distributed, filed with
the SEC, or received by the Company (but not later than two (2) Business Days after the filing date, receipt date or sending date, as the case may be) one (1) copy of any Registration Statement and any amendment thereto, each preliminary
prospectus and Prospectus and each amendment or supplement thereto, and each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case
relating to such Registration Statement (other than any portion of any thereof which contains information for which the Company has sought confidential treatment), and (ii) such number of copies of a Prospectus, including a preliminary
prospectus, and all amendments and supplements thereto and such other documents as each Purchaser may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Purchaser that are covered by the related
Registration Statement; 
 (e) use commercially reasonable efforts to (i) prevent the issuance of any stop order or other
suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest possible moment; 

(f) prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with
the Purchasers and their counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions requested by the Purchasers and do any and all other
commercially reasonable acts or things necessary or advisable to enable the distribution in such jurisdictions of the Registrable Securities covered by 

 

 -5- 

 
the Registration Statement; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (i) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this Section 3(f), (ii) subject itself to general taxation in any jurisdiction where it would not otherwise be so subject but for this Section 3(f), or (iii) file a
general consent to service of process in any such jurisdiction; 
 (g) use commercially reasonable efforts to cause all
Registrable Securities covered by a Registration Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed; 

(h) immediately notify the Purchasers, at any time prior to the end of the Effectiveness Period, upon discovery that, or upon the
happening of any event as a result of which, the Prospectus includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly prepare, file with the SEC and furnish to such holder a supplement to or an amendment of such Prospectus as may be necessary so that such Prospectus shall not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and 

(i) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC under the 1933 Act and
the 1934 Act, including, without limitation, Rule 172 under the 1933 Act, file any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the 1933 Act, promptly inform the Purchasers in writing if,
at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Purchasers are required to deliver a Prospectus in connection with any disposition of Registrable Securities
and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and make available to its security holders, as soon as reasonably practicable, but not later than the Availability
Date (as defined below), an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of
the 1933 Act, including Rule 158 promulgated thereunder (for the purpose of this subsection 3(i), “Availability Date” means the 45th day following the end of the fourth fiscal quarter that includes the effective date of such Registration
Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 90th day after the end of such fourth fiscal quarter). 

(j) With a view to making available to the Purchasers the benefits of Rule 144 (or its successor rule) and any other rule or regulation
of the SEC that may at any time permit the Purchasers to sell shares of Common Stock to the public without registration, the Company covenants and agrees to: (i) make and keep public information available, as those terms are understood and
defined in Rule 144, until the earlier of (A) six months after such date as all of the Registrable Securities may be sold without restriction by the holders thereof pursuant to Rule 144 or any other rule of similar effect or (B) such date
as all of the Registrable Securities shall have been resold; (ii) file with the SEC in a timely manner all reports and other 

 

 -6- 

 
documents required of the Company under the 1934 Act; and (iii) furnish to each Purchaser upon request, as long as such Purchaser owns any Registrable Securities, (A) a written
statement by the Company that it has complied with the reporting requirements of the 1934 Act, (B) a copy of the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may
be reasonably requested in order to avail such Purchaser of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration. 

4. Due Diligence Review; Information. The Company shall make available, during normal business hours, for inspection and review by
the Purchasers, advisors to and representatives of the Purchasers (who may or may not be affiliated with the Purchasers and who are reasonably acceptable to the Company), all financial and other records, all SEC Filings (as defined in the Purchase
Agreement) and other filings with the SEC, and all other corporate documents and properties of the Company as may be reasonably necessary for the purpose of such review, and cause the Company’s officers, directors and employees, within a
reasonable time period, to supply all such information reasonably requested by the Purchasers or any such representative, advisor or underwriter in connection with such Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them), prior to and from time to time after the filing and effectiveness of the Registration Statement for the sole purpose of enabling the Purchasers and such representatives,
advisors and underwriters and their respective accountants and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of such Registration Statement. 

The Company shall not disclose material nonpublic information to the Purchasers, or to advisors to or representatives of the Purchasers,
unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Purchasers, such advisors and representatives with the opportunity to accept or refuse to accept such
material nonpublic information for review and any Purchaser wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto. 

5. Obligations of the Purchasers. 

(a) Each Purchaser shall furnish in writing to the Company such information regarding itself, the Registrable Securities held by it and
the intended method of disposition of the Registrable Securities held by it, as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the
Company may reasonably request. At least five (5) Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Purchaser of the information the Company requires from such Purchaser if
such Purchaser elects to have any of the Registrable Securities included in the Registration Statement. A Purchaser shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such
Registration Statement if such Purchaser elects to have any of the Registrable Securities included in the Registration Statement. The Company shall not be required to include the Registrable Securities of a Holder in a Registration Statement and
shall not be required to pay any liquidated or other damages under Sections 2(a) and 2(c) hereof to such Holder who fails to furnish to the Company a fully completed selling holder questionnaire at least two Business Days prior to the Filing Date.

  

 -7- 

 (b) Each Purchaser, by its acceptance of the Registrable Securities agrees to cooperate
with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Purchaser has notified the Company in writing of its election to exclude all of its Registrable
Securities from such Registration Statement. 
 (c) Each Purchaser agrees that, upon receipt of any notice from the Company of
either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(h) hereof, such Purchaser will immediately discontinue disposition of Registrable Securities
pursuant to the Registration Statement covering such Registrable Securities, until the Purchaser is advised by the Company that such dispositions may again be made. 

6. Indemnification. 

(a) Indemnification by the Company. The Company will indemnify and hold harmless each Purchaser and its officers, directors,
members, partners, employees and agents, successors and assigns, and each other person, if any, who controls such Purchaser within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may
become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement or omission or alleged
omission of any material fact contained in any Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically
for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or
information herein called a “Blue Sky Application”); (iii) the omission or alleged omission to state in a Blue Sky Application a material fact required to be stated therein or necessary to make the statements therein not misleading;
(iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; or
(v) any failure to register or qualify the Registrable Securities included in any such Registration Statement in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such
registration or qualification on a Purchaser’s behalf and will reimburse such Purchaser, and each such officer, director or member and each such controlling person for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or
is based upon (i) a Purchaser’s failure to comply with the prospectus delivery requirements of the 1933 Act, (ii) the use by a Purchaser of an outdated or defective Prospectus after the Company has notified such Purchase in writing
that the Prospectus is outdated or defective, or (iii) an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Purchaser or any such controlling person in writing
specifically for use in such Registration Statement or Prospectus or Blue Sky Application. 
  

 -8- 

 (b) Indemnification by the Purchasers. Each Purchaser agrees, severally but not
jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims,
damages, liabilities and expense (including reasonable attorney fees) resulting from (i) such Purchaser’s failure to comply with the prospectus delivery requirements of the 1933 Act; (ii) the use by such Purchaser of an outdated or
defective Prospectus after the Company has notified such Purchase in writing that the Prospectus is outdated or defective; or (iii) any untrue statement of a material fact or any omission of a material fact required to be stated in the
Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or in any Blue Sky Application or necessary to make the statements therein not misleading, (A) to the extent, but only to the extent that
(1) such untrue statement or omission is contained in any information furnished in writing by such Purchaser to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto or Blue Sky
Application or (2)such information relates to such Purchaser or such Purchaser’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in a Registration
Statement (it being understood that the Purchaser has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto. In no event shall the liability of a Purchaser be greater
in amount than the dollar amount of the proceeds (net of all expense paid by such Purchaser in connection with any claim relating to this Section 6 and the amount of any damages such Purchaser has otherwise been required to pay by reason of
such untrue statement or omission) received by such Purchaser upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation, except in the case of fraud or willful misconduct by
such Purchaser. 
 (c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall
(i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the
expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person
or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the
indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and
provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall
materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any 

 

 -9- 

 
proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except
with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all
liability in respect of such claim or litigation. 
 Subject to the terms of this Agreement, all reasonable fees and expenses of an indemnified
party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such proceeding in a manner not inconsistent with this Section) shall be paid to the indemnified party, as incurred;
provided, that the indemnified party shall promptly reimburse the indemnifying party for that portion of such fees and expenses applicable to such actions for which it is finally judicially determined (not subject to appeal) such indemnified party
is not entitled to indemnification hereunder. 
 (d) Contribution. If for any reason the indemnification provided for in
the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the
indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No
person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation
of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has
otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation except in the case of fraud
or willful misconduct by such holder. 
 7. Miscellaneous. 

(a) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Required Purchasers.
The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company shall have obtained the written consent to such amendment, action or omission to act, of the Required
Purchasers. 
 (b) Notices. All notices and other communications provided for or permitted hereunder shall be made as
set forth in Section 5.4 of the Purchase Agreement. 
 (c) Assignments and Transfers by Purchasers. The provisions
of this Agreement shall be binding upon and inure to the benefit of the Purchasers and their respective successors and assigns. A Purchaser may transfer or assign, in whole or from time to time in part, to one or more persons its rights hereunder in
connection with the transfer of Registrable 
  

 -10- 

 
Securities by such Purchaser to such person, provided that such Purchaser complies with all laws applicable thereto and provides written notice of assignment to the Company promptly after such
assignment is effected. 
 (d) Assignments and Transfers by the Company. This Agreement may not be assigned by the
Company (whether by operation of law or otherwise) without the prior written consent of the Required Purchasers, provided, however, that in the event that the Company is a party to a merger, consolidation, share exchange or similar business
combination transaction in which the Common Stock is converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the
obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Registrable Securities” shall be deemed to include the securities received by the Purchasers in connection with such
transaction unless such securities are otherwise freely tradable by the Purchasers after giving effect to such transaction. 

(e) Restriction on Other Registration Statements. The Company shall not file with the SEC a registration statement under the
Securities Act (other than the Registration Statement) or a prospectus supplement relating to the resale of the Company’s securities held by third parties, other than a registration statement on Form S-8 or in connection with an acquisition on
Form S-4, until the earlier of (i) the date that is thirty (30) days after the Registration Statement contemplated in Section 2(a) of this Agreement is declared effective and (ii) the date that all Registrable Securities are

 Exhibit A 

Plan of Distribution 

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of
common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of
any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing
market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. 

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein: 

 

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

 

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to
facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

  

	 	•	 	 short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC;

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

  

	 	•	 	 broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

  

	 	•	 	 a combination of any such methods of sale; and 

  

	 	•	 	 any other method permitted by applicable law. 

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned
by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this

 
prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as
selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners
for purposes of this prospectus. 
 In connection with the sale of our common stock or interests therein, the selling
stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also
sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option
or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus,
which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). 

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the
common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made
directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants. 

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the
Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule. 
 The selling
stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts,
commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the
Securities Act will be subject to the prospectus delivery requirements of the Securities Act. 
 Each selling stockholder has
advised us that they have not entered into any written or oral agreements, understandings or arrangements with any underwriter or broker-dealer regarding the sale of the resale shares. There is no underwriter or coordinating broker acting in
connection with the proposed sale of the resale shares by the selling stockholders. 
 To the extent required, the shares of our
common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer
will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus. 

 

 -17- 

 In order to comply with the securities laws of some states, if applicable, the common stock
may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or
qualification requirements is available and is complied with. 
 We have advised the selling stockholders that the
anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable we will make copies of this
prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any
broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act. 

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state
securities laws, relating to the registration of the shares offered by this prospectus. 
 We have agreed with the selling
stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with
the registration statement or (2) the date on which the shares may be sold without restriction pursuant to Rule 144 of the Securities Act.

 AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the Parties agree as
follows. 
 ARTICLE I. 

REGISTRATION RIGHTS 

Section 1.1 Definitions. For purposes of this Agreement: 

“Affiliate” means, with respect to any Person, (i) any other Person of which securities or other ownership
interests representing more than 50% of the voting interests are, at the time such determination is being made, owned, Controlled or held, directly or indirectly, by such Person or (ii) any other Person which, at the time such determination is
being made, is Controlling, Controlled by or under common Control with, such Person. “Control”, whether used as a noun or verb, refers to the possession, directly or indirectly, of the power to direct, or cause the direction
of, the management or policies of a Person, whether through the ownership of voting securities or otherwise. 

“Holder” means a Person that (i) is a party to this Agreement (or a permitted transferee under
Section 2.2) and (ii) owns Registrable Securities; provided, however, that for purposes of this Agreement, Holders of Registrable Securities will not be required to convert the Note or exercise the Warrant into Common
Stock to exercise the registration rights granted hereunder, until immediately before the closing of the offering to which the registration relates. 

“Participating Holders” means Holders participating, or electing to participate, in an offering of Registrable
Securities. 

 “Person” means any individual, firm, corporation, company,
partnership, trust, incorporated or unincorporated association, limited liability company, joint venture, joint stock company, government (or an agency or political subdivision thereof) or other entity of any kind, and will include any successor (by
merger or otherwise) of any such entity. 
 “Registrable Securities” means any shares of Common Stock
(i) issued or issuable upon conversion of the Note; (ii) issued or issuable upon exercise of the Warrant; (iii) otherwise held or which could be held upon conversion or exercise by the Purchaser; and (iv) issued or issuable with
respect to the securities referred to in clauses (i) - (iii) above by virtue of any stock split, combination, stock dividend, merger, consolidation or other similar event; provided, however, that shares of Common Stock that are
considered to be Registrable Securities will cease to be Registrable Securities (A) upon the sale thereof pursuant to an effective registration statement, (B) upon the sale thereof pursuant to Rule 144 (or successor rule) under the
Securities Act where the purchaser thereof receives unrestricted securities, (C) when such securities cease to be outstanding or (D) in a private transaction where the transferor’s rights under this Agreement are not assigned.

from or incident to the performance of or compliance with this Agreement, including without limitation (i) SEC, stock exchange, the Financial Industry Regulatory Authority (“FINRA”) and other registration and filing
fees, (ii) all fees and expenses incurred in connection with complying with any securities or blue sky laws, (iii) all printing, messenger and delivery expenses, (iv) the fees, charges and disbursements of counsel to the Company and
of its independent public accountants and any other accounting and legal fees, charges and expenses incurred by the Company (including, without limitation, any expenses arising from any special audits or “comfort letters” required in
connection with or incident to any registration), (v) the fees, charges and disbursements of any special experts retained by the Company in connection with any registration pursuant to the terms of this Agreement, (vi) all internal
expenses of the Company, and (vii) the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange, in each case regardless of whether any Registration Statement is declared effective.

 “Registration Statement” will mean any Registration Statement of the Company filed with the SEC on
the appropriate form pursuant to the Securities Act which covers any of the shares of Common Stock and any other Registrable Securities pursuant to the provisions of this Agreement and all amendments and supplements to any such Registration
Statement, including post-effective amendments, in each case including the prospectus contained therein, all exhibits thereto and all materials incorporated by reference therein. 

“SEC” means the United States Securities and Exchange Commission. 

“Selling Expenses” will mean the underwriting fees, discounts, selling commissions and stock transfer taxes
applicable to all Registrable Securities registered by the Participating Holders. 
 Section 1.2 Filing of Registration
Statement. Obligation to File Registration Statement. The Company will, within 45 days after the earliest of the Company obtaining  

 

 2 

 
stockholder approval of the issuance of Common Stock under the Warrant and Note, obtaining a letter from Nasdaq exempting the Company from obtaining such shareholder approval, or determining that
such stockholder approval is not required, file a Registration Statement under the Securities Act covering the sale or other distribution of all or any portion of the Registrable Securities pursuant to Rule 415 under the Securities Act. The Company
will use its reasonable efforts to have such Registration Statement declared effective by the SEC as soon as practicable thereafter (the “Effectiveness Deadline”). 

(a) Liquidated Damages. To the extent (a) the Registration Statement required pursuant to this
Section 1.2 is not filed with the SEC on or prior to the Effectiveness Deadline, (b) such Registration Statement has not been declared effective by the SEC on or prior to the Effectiveness Deadline, or (c) such Registration
Statement is filed and declared effective but thereafter ceases to be effective or fails to be usable for its intended purpose without being succeeded within five days by a post-effective amendment thereto that cures such failure and that is itself
declared effective within five days of filing such post-effective amendment (each, a “Registration Default”), then the Company will pay to each Holder liquidated damages in an amount equal to one percent (1%) of the
original principal amount owed under the Note, for each month or portion thereof that the Registration Default continues. However, in no event shall the Company pay liquidated damages in excess of ten percent (10%) of the principal amount of
the Notes in total to each Holder. Any liquidated damages paid hereunder by the Company shall not be considered the charge for or payment of interest under the Notes. 

(b) Continuing Agreements. The event of a Registration Default and payment of liquidated damages by the Company will not
relieve, impair, adjust, modify or any way change the obligations of the Company under the Loan Documents. 
 Section 1.3
Piggyback Registrations. 
 (a) Right to Include Registrable Securities. In the event that a
Registration Default has occurred and is continuing, and thereafter the Company from time to time proposes for any reason to register any of its Common Stock under the Securities Act, either for its own account or for the account of a stockholder
other than pursuant to a Registration Statement on Forms S-4 or S-8 (or similar or successor forms) or pursuant to one or more secured bridge financing transactions from the Issuance Date of the Note and through the later to occur of the Maturity
Date or the date upon which the Note is paid in full (a “Proposed Registration”), the Company will promptly give written notice thereof to all of the Holders (which notice will be given not less than 30 days prior to the
expected effective date of the Company’s Registration Statement) and will offer such Holders the right to request inclusion of any of such Holder’s Registrable Securities in the Proposed Registration. No registration pursuant to this
Section 1.3 will relieve the Company of its obligation to register Registrable Securities pursuant to Section 1.2, to pay liquidated damages or under the Loan Documents. 

 

 3 

 (b) Piggyback Procedure. Each Holder of Registrable
Securities will have 20 days from the date of receipt of the Company’s notice referred to in Section 1.3(a) to deliver to the Company a written request specifying the number of Registrable Securities such Holder intends to sell and
such Holder’s intended method of disposition. Any Holder will have the right to withdraw such Holder’s request for inclusion of such holder’s Registrable Securities in any Registration Statement pursuant to this
Section 1.3 by giving written notice to the Company of such withdrawal. Subject to Section 1.3(d), the Company will use commercially reasonable efforts to include in such Registration Statement all such Registrable Securities
so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such Proposed Registration if it will at the same time withdraw or cease proceeding with the registration of
all other shares of Common Stock originally proposed to be registered. If the Proposed Registration by the Company is, in whole or in part, an underwritten public offering of securities of the Company, any request under this
Section 1.3(b) will specify that the Registrable Securities be included in the underwriting on the same terms and conditions as the shares, if any, otherwise being sold through underwriters under such registration. If the Company fails
to notify Holder or to include Holder’s Registrable Securities in the Proposed Registration as provided in Section 1.3(a) or (b) or the Registrable Securities are excluded under Section 1.3(d), the Company will pay
Holder liquidated damages in an amount equal to one percent (1%) of the original principal amount of the indebtedness owed under the Note, for each month or portion thereof that the default continues, subject to the limitations on liquidated
damages found in Section 1.2 (a). 
 (c) Selection of Underwriters. The managing underwriter for any
Proposed Registration that involves an underwritten public offering will be one or more reputable nationally recognized investment banks selected by the Company and reasonably acceptable to a majority in interest of the Holders. 

(d) Priority for Piggyback Registration. Notwithstanding any other provision of this Article 1, if the
managing underwriter of an underwritten public offering determines in good faith and advises the Company and the Holders that the inclusion of all Registrable Securities proposed to be included by the Holders of Registrable Securities in such
offering would materially and adversely interfere with the successful marketing of the Company’s securities, then the Holders of Registrable Securities will not be permitted to include any Registrable Securities in excess of the amount, if any,
of Registrable Securities which the managing underwriter of such offering will reasonably and in good faith agree in writing to include in such offering in addition to the amount of securities to be registered for the Company. The Company will
include in such Registration Statement, as to each Holder, only a portion of the Registrable Securities such Holder has requested be registered equal to the ratio which such Holder’s requested Registrable Securities bears to the total number of
Registrable Securities requested to be included in such Registration Statement by all Holders. Pursuant to the foregoing provision, the securities to be included in a registration initiated 

 

 4 

 
by the Company will be allocated: (i) first, to the Company; (ii) second, pari passu to the Holders; and (iii) third, to any others requesting registration of securities of the
Company. 
 Section 1.4 Registration Procedures. 

(a) Obligations of the Company. Whenever registration of Registrable Securities is required pursuant to this
Agreement, the Company will use its reasonable efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method of distribution thereof as promptly as possible, and in connection with any such
request, the Company will, as expeditiously as possible: 
 (i) Preparation of Registration Statement;
Effectiveness. Prepare and file with the SEC a Registration Statement on any form on which the Company then qualifies, which counsel for the Company will deem appropriate and pursuant to which such offering may be made in accordance with the
intended method of distribution thereof (except that the Registration Statement will contain such information as may reasonably be requested for marketing or other purposes by the managing underwriter), and use reasonable best efforts to cause any
registration required hereunder to become effective as soon as practicable after the initial filing thereof (unless a specific time period is otherwise set forth herein) and remain effective for a period of not less than one year from the effective
date thereof or such shorter period in which all Registrable Securities have been sold in accordance with the methods of distribution set forth in the Registration Statement; provided that, in the case of any registration of Registrable
Securities on Form S-3 which are intended to be offered on a continuous or delayed basis, such one-year period will be extended, if necessary, to keep the Registration Statement effective until all such Registrable Securities are sold,
provided that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis; 

(ii) Participation in Preparation. Provide any Participating Holder, any underwriter participating in any
disposition pursuant to a Registration Statement, and any attorney, accountant or other agent retained by any Participating Holder or underwriter (collectively, the “Inspectors”), the opportunity to participate
in the preparation of such Registration Statement, each prospectus included therein or filed with the SEC and each amendment or supplement thereto; 

(iii) Due Diligence. For a reasonable period prior to the filing of any Registration Statement pursuant to this
Agreement, make available for inspection and copying by the Inspectors such financial and other information and books and records, pertinent corporate documents and properties of the Company and its subsidiaries and cause the officers,

  

 5 

 
directors, employees, counsel and independent certified public accountants of the Company and its subsidiaries to respond to such inquiries and to supply all information reasonably requested by
any such Inspector in connection with such Registration Statement, as will be reasonably necessary, in the judgment of the respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act; provided,
however, that if requested by the Company, each Inspector will enter into a confidentiality agreement with the Company prior to the Company’s release or disclosure of confidential information to such Inspector; 

(iv) General Notifications. Promptly notify in writing the Participating Holders, the sales or placement agent, if
any, therefor and the managing underwriter of the securities being sold, (A) when such Registration Statement or the prospectus included therein or any prospectus amendment or supplement or post-effective amendment has been filed, and, with
respect to any such Registration Statement or any post-effective amendment, when the same has become effective, (B) when the SEC notifies the Company whether there will be a “review” of such Registration Statement and (C) of any
comments (oral or written) by the SEC and by the blue sky or securities commissioner or regulator of any state with respect thereto or (D) of any request by the SEC for any amendments or supplements to such Registration Statement or the
prospectus or for additional information; 
 (v) 10b-5 Notification. Promptly notify in writing the
Participating Holders, the sales or placement agent, if any, therefor and the managing underwriter of the securities being sold pursuant to any Registration Statement at any time when a prospectus relating thereto is required to be delivered under
the Securities Act upon discovery that, or upon the happening of any event as a result of which, any prospectus included in such Registration Statement (or amendment or supplement thereto) contains an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, and the Company will promptly prepare a supplement or amendment to such
prospectus and file it with the SEC (in any event no later than ten days following notice of the occurrence of such event to each Participating Holder, the sales or placement agent and the managing underwriter) so that after delivery of such
prospectus, as so amended or supplemented, to the purchasers of such Registrable Securities, such prospectus, as so amended or supplemented, will not contain an untrue statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made; 
  

 6 

 (vi) Notification of Stop Orders; Suspensions of Qualifications and
Exemptions. Promptly notify in writing the Participating Holders, the sales or placement agent, if any, therefor and the managing underwriter of the securities being sold of the issuance by the SEC of (A) any stop order issued or threatened
to be issued by the SEC or (B) any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose and the Company will use reasonable efforts to (x) prevent the issuance of any such stop order, and in the event of such issuance, to obtain the withdrawal of any such stop order and (y) obtain the withdrawal of
any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction at the earliest practicable date; 

(vii) Amendments and Supplements; Acceleration. Prepare and file with the SEC such amendments, including
post-effective amendments, as may be necessary to keep each Registration Statement continuously effective for the applicable time period required hereunder and if applicable, file any Registration Statements pursuant to Rule 462(b) under the
Securities Act; cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply
with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof
set forth in such Registration Statement as so amended or in such prospectus as so supplemented; 
 (viii)
Copies. Furnish as promptly as practicable to each Participating Holder copies of such Registration Statement, supplement or amendment as it is proposed to be filed, and after such filing such number of copies of such Registration Statement,
each amendment and supplement thereto (in each case including all exhibits thereto), the prospectus included in such Registration Statement (including each preliminary prospectus) and such other documents as each such Participating Holder or
underwriter may reasonably request; 
 (ix) Blue Sky. Use reasonable efforts to, prior to any public
offering of the Registrable Securities, register or qualify (or seek an exemption from registration or qualifications) such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any Participating Holder or
underwriter may request, and to continue such qualification in effect in each such jurisdiction for as long as is permissible pursuant to the laws of such jurisdiction, or for as long as a Participating

  

 7 

 
Holder or underwriter requests or until all of such Registrable Securities are sold, whichever is shortest, and do any and all other acts and things which may be reasonably necessary or advisable
to enable any Participating Holder to consummate the disposition in such jurisdictions of the Registrable Securities; 

(x) Other Approvals. Use reasonable efforts to obtain all other approvals, consents, exemptions or authorizations
from such governmental agencies or authorities as may be necessary to enable the Participating Holders and underwriters to consummate the disposition of Registrable Securities; 

(xi) “Cold Comfort” Letter. Obtain a “cold comfort” letter from the Company’s
independent public accountants in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing underwriter may reasonably request, and reasonably satisfactory to a majority in interest
of the Participating Holders; 
 (xii) Legal Opinion. Furnish, at the request of any underwriter of
Registrable Securities on the date such securities are delivered to the underwriters for sale pursuant to such registration, an opinion, dated such date, of counsel representing the Company for the purposes of such registration, addressed to the
Holders, and the placement agent or sales agent, if any, thereof and the underwriters, if any, thereof, covering such legal matters with respect to the registration in respect of which such opinion is being given as such underwriter may reasonably
request and as are customarily included in such opinions; 
 (xiii) Certificates, Closing. Provide
officers’ certificates and other customary closing documents; 
 (xiv) FINRA. Cooperate with each
Participating Holder and each underwriter participating in the disposition of such Registrable Securities and underwriters’ counsel in connection with any filings required to be made with the FINRA; 

(xv) Listing. Use reasonable efforts to cause all such Registrable Securities to be listed on each securities
exchange on which similar securities issued by the Company are then listed and if not so listed, to be listed on the over-the-counter system; 

(xvi) Private Sales. Use reasonable efforts to assist a Holder in facilitating private sales of Registrable
Securities by, among other things, providing officers’ certificates and other customary closing documents reasonably requested by a Holder; and 
  

 8 

 (xvii) Reasonable Efforts. Use reasonable efforts to take all other
actions necessary to effect the registration of the Registrable Securities contemplated hereby. 
 (b) Seller
Information. The Company may require each Participating Holder as to which any registration of such Holder’s Registrable Securities is being effected to furnish to the Company with such information regarding such Participating Holder and
such Participating Holder’s method of distribution of such Registrable Securities as the Company may from time to time reasonably request in writing. 

(c) Notice to Discontinue. Each Participating Holder whose Registrable Securities are covered by a Registration

Section 1.6 Indemnification 

(a) Indemnification by the Company. Notwithstanding termination of this Agreement, the Company will indemnify and
hold harmless to the fullest extent permitted by law, each Holder, each of its directors, officers, employees, advisors, agents and general or limited partners (and the directors, officers, employees, advisors and agents thereof), their respective
Affiliates and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any of such Persons, and each underwriter and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any
underwriter (collectively, “Holder Indemnified Parties”) from and against any and all losses, claims, damages, expenses (including, without limitation, reasonable costs of investigation and fees, disbursements
and other charges of counsel, any amounts paid in settlement effected with the Company’s consent, which consent will not 
  

 9 

 
be unreasonably withheld or delayed and any costs incurred in enforcing the Company’s indemnification obligations hereunder) or other liabilities (collectively,
“Losses”) to which any such Holder Indemnified Party may become subject under the Securities Act, Exchange Act, any other federal law, any state or common law or any rule or regulation promulgated thereunder or
otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) are resulting from or arising out of or based upon (i) any untrue, or alleged untrue, statement of a material fact contained in
any Registration Statement, prospectus or preliminary prospectus (as amended or supplemented) or any document incorporated by reference in any of the foregoing or resulting from or arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made), not misleading or (ii) any violation by the Company
of the Securities Act, Exchange Act, any other federal law, any state or common law or any rule or regulation promulgated thereunder or otherwise incident to any registration, qualification or compliance or (iii) any violation by the Company of
this Agreement, and in any such case, the Company will promptly reimburse each such Holder Indemnified Party for any legal and any other Losses reasonably incurred in connection with investigating, preparing or defending any such claim, loss,
damage, liability, action or investigation or proceeding (collectively, a “Claim”); provided, however, that the liability of the Company under this Section 1.6(a) will be limited to an amount equal
to the sum of the principal amount of the Note plus all accrued unpaid interest earned thereon at the time the Claim was made and the exercise price of the Warrant and that the Company will not be liable to any Holder Indemnified Party for any
Losses that arise out of or are based upon (x) written information provided by a Holder Indemnified Party expressly for use in the Registration Statement or (y) sales of Registrable Securities by a Holder Indemnified Party to a person to
whom there was not sent or given, at or before the written confirmation of such sale, a copy of the prospectus (excluding documents incorporated by reference) or the prospectus as then amended or supplemented (excluding documents incorporated by
reference) if the Company has previously furnished in a timely manner a reasonable number of copies thereof to such Holder Indemnified Party in compliance with this Agreement and the Losses of such Holder Indemnified Party results from an untrue
statement or omission of a material fact contained in such preliminary prospectus which was corrected in the prospectus (or the prospectus as then amended or supplemented). Such indemnity will remain in full force and effect regardless of any
investigation made by or on behalf of the Holder Indemnified Parties and will survive the transfer of Registrable Securities by such Holder Indemnified Parties. 

(b) Indemnification by Holders. In connection with any proposed registration in which a Holder is participating
pursuant to this Agreement, each such Holder will furnish to the Company in writing such information with respect to such Holder as the Company may reasonably request or as may be required by law for use in connection with any Registration Statement
or prospectus or 
  

 10 

 
preliminary prospectus to be used in connection with such registration and each Holder, severally and not jointly, will indemnify and hold harmless the Company, any underwriter retained by the
Company and their respective directors, officers, partners, employees, advisors and agents, their respective Affiliates and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any of such Persons to the same
extent as the foregoing indemnity from the Company to the Holders as set forth in Section 1.6(a) (subject to the exceptions set forth in the foregoing indemnity, the proviso to this sentence and applicable law), but only with respect to
any such information furnished in writing by such Holder expressly for use therein and not with respect to any other Holder or the Company; provided, however, that the liability of any Holder under this Section 1.6(b) will
be limited to the amount of the net proceeds received by such Holder in the offering giving rise to such liability. Such indemnity obligation will remain in full force and effect regardless of any investigation made by or on behalf of the Holder
Indemnified Parties (except as provided above) and will survive the transfer of Registrable Securities by such Holder. 

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder (the
“Indemnified Party”) will give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of
the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that,
the failure so to notify the Indemnifying Party will not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder unless and to the extent such Indemnifying Party is materially prejudiced by such failure.
If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party will be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly
notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party. The Indemnified Party will have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel will be paid by the Indemnified Party unless the Indemnifying Party fails to assume the defense of such action with counsel The Indemnifying Party will not have the right
to assume the defense of such action on behalf of such Indemnified Party. No Indemnifying Party will be liable for any settlement entered into without its written consent, which consent will not be unreasonably withheld. No Indemnifying Party will,
without the written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may
be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the Indemnified Party from all liability
arising out of such action or claim and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any 

 

 11 

 
Indemnified Party. The rights afforded to any Indemnified Party hereunder will be in addition to any rights that such Indemnified Party may have at common law, by separate agreement or otherwise.

 (d) Contribution. If the indemnification provided for in this Section 1.6
from the Indemnifying Party is unavailable or insufficient to hold harmless an Indemnified Party in respect of any Losses referred to herein, then the Indemnifying Party, in lieu of indemnifying the Indemnified Party, will contribute to the amount
paid or payable by the Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the Indemnified Party, as well as any other relevant equitable considerations. The
relative faults of the Indemnifying Party and Indemnified Party will be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact, was made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the Indemnifying Party’s and Indemnified Party’s relative intent, knowledge, access to information and
opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 1.6(d) will be limited to the amount of the net proceeds received by such Holder in the offering giving
rise to such liability and the liability of the Company will be limited to an amount as stated in Section 1.6(a). The amount paid or payable by a party as a result of the Losses or other liabilities referred to above will be deemed to
include, subject to the limitations set forth in Sections 1.6(a), 1.8(b) and 1.6(c), any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The Parties
agree that it would not be just and equitable if contribution pursuant to this Section 1.6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations
referred to in the foregoing. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution pursuant to this Section 1.6(d). 

Section 1.7 Rule 144 and Rule 144A; Other Exemptions. With a view to making available to the Holders the benefits of
Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration, the Company covenants that it will
(i) file in a timely manner all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and (ii) take such further action as each
Holder may reasonably request (including, but not limited to, providing any information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act), at all times from
and after the date hereof all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule
144A (if available with respect to resales of the Registrable Securities) under the Securities Act, as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC. 

 

 12 

 Section 1.8 Certain Limitations On Registration Rights. No Holder may
participate in any Registration Statement hereunder unless such Holder completes and executes all questionnaires and other documents reasonably required and will sell such Holder’s Registrable Securities on the basis provided in any
underwriting agreement approved by the Holder or Holders entitled hereunder to approve such arrangements. Such Holders of Registrable Securities to be sold by such underwriters may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of the Company to and for the benefit of such underwriters, will also be made to and for the benefit of such Holders and that any or all of the conditions precedent to the obligations of the
underwriters under the underwriting agreement be conditions precedent to the obligations of the Holders.
