 2. REGISTRATION RIGHTS. 

(a) Registration Statements. 

(i) Promptly following the Effective Date but no later than thirty (30) days after the Effective Date (the “Filing
Deadline”), the Company shall prepare and file with the SEC a Registration Statement covering the resale of all of the Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415 under the 1933 Act
(“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 Investors may reasonably specify (the “Initial
Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is then ineligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on such other form available to register for resale the Registrable Securities as a secondary offering) subject to the provisions of
Section 2(a)(ii) and shall contain (except if otherwise required pursuant to written comments received from the SEC upon review of such Registration Statement) a “Plan of Distribution” substantially in the
form attached hereto as Exhibit A (which may be modified to respond to comments, if any, provided by the SEC); provided, however, that no Investor shall be named as an “underwriter” in such Registration Statement
without the Investor’s prior written consent. In the event that the Company is not eligible to register the Registrable Securities on Form S-3 and instead registers the Registrable Securities on another
form of registration statement pursuant to the 1933 Act, the Company shall convert or replace such registration statement with a registration statement on Form S-3 promptly following confirmation that the
Company becomes eligible to use Form S-3 to register the Registrable Securities. 

  
 -2- 

 (ii) 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 combinations, stock dividends or similar transactions with respect to the Registrable
Securities. Such 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 Investors prior to its
filing or other submission. 
 (b) Expenses. The Company will pay all expenses associated with each Registration Statement, 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, but excluding discounts, commissions,
fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold. 

(c) Effectiveness. 
 (i)
The Company shall use commercially reasonable efforts to have each Registration Statement declared effective as soon as practicable after the filing. The Company shall notify the Investors as promptly as practicable, and in any event, within
twenty-four (24) hours, after the Registration Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities
covered thereby. 
 (ii) For not more than ten (10) consecutive days or for a total of not more than twenty (20) 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 2 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 any Misstatement (an “Allowed Delay”); provided,
that the Company shall promptly (1) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material
non-public information giving rise to an Allowed Delay, (2) advise the Investors in writing to cease all sales under such Registration Statement until the end of the Allowed Delay and (3) use
commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable. 
 (d) Liquidated Damages. If: (i) the
Registration Statement is not filed on or prior to the Filing Deadline, (ii) the Company fails to file with the SEC a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by the SEC pursuant to the 1933
Act, within five (5) Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the SEC that such Registration Statement will not be “reviewed” or will not be subject to further review,
(iii) prior to the effective date of a Registration Statement, the Company fails to file a pre-effective amendment and otherwise respond in writing to comments made by the SEC in respect of such
Registration Statement within ten (10) calendar days after the receipt of comments by or notice from the SEC that such amendment is required in order for such Registration Statement to be declared effective, or (iv) the Company fails to
maintain the 

  
 -3- 

 
effectiveness of the Registration Statement during the Effectiveness Period other than in connection with an Allowed Delay, or the Allowed Delay is exceeded (any such failure or breach being
referred to as an “Event”, and for purpose of clause (i), the date on which such Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period is exceeded, and for purpose of clause
(iii) the date which such ten (10) calendar day period is exceeded, and for purpose of clause (iv) the date on which the Allowed Delay, is exceeded being referred to as the “Event Date”), then, in addition to any
other rights the Investors may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is
cured, the Company shall pay to each Investor an amount in cash, as partial liquidated damages and not as a penalty, equal to the product of 1.0% multiplied by the aggregate Purchase Price paid by such Investor pursuant to the Securities Purchase
Agreement. The amounts payable pursuant to the foregoing sentence are referred to collectively as “Liquidated Damages”. The parties agree that (1) notwithstanding anything to the contrary herein or in the Securities Purchase
Agreement, no Liquidated Damages shall be payable with respect to any period after the expiration of the Effectiveness Period and in no event shall the aggregate amount of Liquidated Damages payable to an Investor pursuant to this Section 2.(d)
exceed, in the aggregate, five percent (5%) of the aggregate purchase price paid by such Investor pursuant to the Securities Purchase Agreement and (2) in no event shall the Company be liable in any thirty
(30)-day period for Liquidated Damages under this Agreement in excess of one percent (1.0)% of the aggregate purchase price paid by the Investors pursuant to the Securities Purchase Agreement. If the Company
fails to pay any Liquidated Damages pursuant to this Section 2(d) in full within seven (7) calendar days after the date payable, the Company will pay interest thereon at a rate of one percent (1.0%) per annum (or such lesser maximum amount
that is permitted to be paid by applicable Law) to the Investor, accruing daily from the date such Liquidated Damages are due until such amounts, plus all such interest thereon, are paid in full. The Liquidated Damages pursuant to the terms hereof
shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event. The Effectiveness Deadline for a Registration Statement shall be extended without default and without the payment of Liquidated Damages hereunder in the
event that the Company’s failure to obtain the effectiveness of the Registration Statement on a timely basis results from the failure of an Investor 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 1933 Act. 
 (e) 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 Investor to be named as an “underwriter,” the Company shall use commercially reasonable efforts to persuade the SEC that the offering contemplated by such 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 Investors is an “underwriter.” The Investors shall have the right to select one legal counsel to review and oversee any registration or matters
pursuant to this Section 2(e), including participation in any meetings or discussions with the SEC regarding the SEC’s position and to comment on any written submission made to the SEC with respect thereto,
which counsel shall be designated by the holders of a majority of the Registrable Securities. No such written submission with respect to this matter shall be made to the SEC to which the Investors’ counsel reasonably objects. In the event that,
despite the Company’s commercially reasonable efforts and compliance with the terms of this Section 2(e), the SEC refuses to alter its position, the Company shall (i)

  
 -4- 

 
remove from such 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 Investor as an “underwriter” in such Registration Statement without the prior written consent of such Investor. Any cut-back imposed on the Investors pursuant to this
Section 2(e) shall be allocated among the Investors on a pro rata basis and shall be applied first to any of the Registrable Securities of such Investor as such Investor shall designate, unless the SEC Restrictions
otherwise require or provide or the Investors otherwise agree. From and after the date on which the Company is able to effect the registration of such Cut Back Shares (such date, the “Restriction Termination Date”), all of the
provisions of this Section 2 (including the Company’s obligations with respect to the filing of a Registration Statement and its obligations to use commercially reasonable efforts to have such Registration Statement
declared effective within the time periods set forth herein) shall again be applicable to such Cut Back Shares; provided, however, that (i) the Filing Deadline for such Registration Statement including such Cut Back Shares shall
be ten (10) Business Days after the 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 (or the 120th day if the SEC reviews such Registration Statement). Notwithstanding anything to the contrary in this Section 2, the Company shall not be liable for Liquidated
Damages under this Agreement as to any Registrable Securities which are not permitted by the SEC to be included in a Registration Statement due solely to the SEC Restrictions. In such case, the Liquidated Damages shall be calculated to only apply to
the percentage of Registrable Securities which are permitted in accordance with the SEC Restrictions to be included in such Registration Statement. 
 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 second anniversary of the Effective Date, and (ii) the date on which all Registrable Securities covered by such Registration Statement may be sold without restriction or limitation
pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1) (or any successor thereto) promulgated under the 1933 Act during any ninety (90) day period (the “Effectiveness Period”) and advise the
Investors promptly in writing when the Effectiveness Period has expired; 
 (b) prepare and file with the SEC such amendments and
post-effective amendments to such Registration Statement and the related Prospectus as may be necessary to keep such 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; 

  
 -5- 

 (c) provide copies to and permit the Investors to review each Registration Statement and all
amendments and supplements thereto not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading Day prior to the filing of any related Prospectus or any amendment or supplement
thereto (except for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar
or successor reports) and not file any document to which such Investor reasonably objects in good faith (it being acknowledged and agreed that if an Investor does not object to or comment on the aforementioned documents within such five
(5) Trading Day or one (1) Trading Day period, as the case may be, then the Investor shall be deemed to have consented to and approved the use of such documents), provided that, the Company is notified of such objection in writing within
the five (5) Trading Day or one (1) Trading Day period described in this Section 3(c), as applicable; 

(d) furnish to each Investor whose Registrable Securities are included in any Registration Statement (i) promptly after the same is
prepared and filed with the SEC, if requested by the Investor, one (1) copy of any Registration Statement and any amendment thereto (provided, that the Company shall have no obligation to provide any document pursuant to this clause that
is available on the SEC’s EDGAR system), 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 Investor may reasonably request in order to facilitate the disposition of the Registrable Securities
owned by such Investor that are covered by such 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 practical moment; 

(f) prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with the
Investors and their counsel in connection with the registration or qualification of such Registrable Securities for the offer and sale under the securities or blue sky laws of such jurisdictions requested by the Investors 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 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) promptly
notify the Investors, 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 (a “Misstatement”), 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 such Misstatement; 

  
 -6- 

 (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 Investors 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 Investors 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 Section 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); and 
 (j) with a view to making available to the Investors 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 Investors 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 (6) 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 documents required of the Company under the 1934 Act;
(iii) prior to the filing of any Registration Statement or any amendment thereto (whether pre-effective or post-effective) and prior to the filing of any Prospectus, provide to each Investor copies of all
pages thereof (if any) that reference such Investors, and (iv) furnish to each Investor upon request, as long as such Investor 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 Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration. 

4. OBLIGATION OF THE INVESTORS. 
 (a) Each
Investor agrees to furnish to the Company a completed Selling Investor Questionnaire on the Effective Date. At least ten (10) Trading Days prior to the first anticipated filing date of a Registration Statement for any registration under this
Agreement, the Company will notify each Investor of the information the Company requires from that Investor other than the information contained in the Selling Investor Questionnaire, if any, which shall be completed

  
 -7- 

 
and delivered to the Company promptly upon request and, in any event, within three (3) Trading Days prior to the applicable anticipated filing date. Each Investor further agrees that it
shall not be entitled to be named as a selling securityholder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless such Investor has returned to the Company a completed and signed
Selling Investor Questionnaire and a response to any reasonable requests for further information as described in the previous sentence. If an Investor returns a Selling Investor Questionnaire or a request for further information, in either case,
after its respective deadline, the Company shall use its reasonable best efforts to take such actions as are required to name such Investor as a selling security holder in the Registration Statement or any
pre-effective or post-effective amendment thereto and to include (to the extent not theretofore included) in the Registration Statement the Registrable Securities identified in such late Selling Investor
Questionnaire or request for further information. Each Investor acknowledges and agrees that the information in the Selling Investor Questionnaire or request for further information as described in this Section 4(a)
will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement. 

(b) Each Investor 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 ten (10) Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Investor of the information the Company requires from such Investor if such Investor
elects to have any of the Registrable Securities included in such Registration Statement. An Investor 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 Investor elects to have any of the Registrable Securities included in such Registration Statement. 
 (c) Each Investor, 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 Investor has notified the
Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. 
 (d) Each Investor agrees
that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(i) or (ii) the happening of an event pursuant to
Section 3(h) hereof, such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement covering such Registrable Securities, until the Investor is advised by the Company
that such dispositions may again be made. 
 (e) Each Investor covenants and agrees that it will comply with the prospectus delivery
requirements of the 1933 Act as applicable to it or an exemption therefrom in connection with sales of Registrable Securities pursuant to any Registration Statement.

 5. INDEMNIFICATION. 

(a) (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Investor, and each of their respective
officers, employees, Affiliates, directors, partners, members, equityholders, attorneys, advisors and agents, and each person or entity, if any, who controls (within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act)
each Investor (each, an “Investor Indemnified Party”), to the fullest extent permitted by applicable law, from and against any expenses, losses, judgments, actions, claims, proceedings (whether commenced or threatened), damages,
liabilities or costs (including, without limitation, reasonable attorneys’ fees), whether joint or several (collectively, “Losses”), as incurred, arising out of or based upon any Misstatement contained in any Registration
Statement under which the sale of such Registrable Securities was Registered under the 1933 Act, any preliminary Prospectus, final Prospectus or summary Prospectus contained in such Registration Statement, or any amendment or supplement to such
Registration Statement, preliminary Prospectus, final Prospectus or summary Prospectus, or any violation by the Company of the 1933 Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction
required of the Company in connection with any such Registration; and the Company shall promptly reimburse the Investor Indemnified Party for any reasonable, customary and documented
out-of-pocket legal and any other expenses incurred, as incurred, by such Investor Indemnified Party in connection with investigating and defending any such Losses,
except, with respect to any Investor of Registrable Securities, to the extent such Investor Securities is liable to indemnify the Company for such Losses pursuant to Section 5(b). 

(b) Indemnification by Investors. Each Investor will, in the event that any Registration is being effected under the 1933 Act pursuant
to this Agreement of any Registrable Securities held by such Investor and the Company has required all Selling Investors to provide such an undertaking on the same terms, indemnify and hold harmless the Company, each of its directors and officers
and each underwriter (if any), and each other Selling Investor and each other person, if any, who controls another Selling Investor or such underwriter within the meaning of the 1933 Act, against any Losses, insofar as such Losses arise out of or
are based upon any Misstatement contained in any Registration Statement under which the sale of such Registrable Securities was Registered under the 1933 Act, any preliminary Prospectus, final Prospectus or summary Prospectus contained in the
Registration Statement, or any amendment or supplement thereto, if the Misstatement was made in reliance upon and in conformity with information furnished in writing to the Company by such Selling Investor expressly for use therein, and shall
reimburse the Company, its directors and officers, and each other Selling Investor for any reasonable, customary and documented out-of-pocket legal or other expenses
incurred by any of them in connection with investigation or defending any such Loss. Each Selling Investor’s indemnification obligations hereunder shall be several and not joint and shall be proportional to and limited to the amount of any net
proceeds actually received by such Selling Investor in connection with the sale of Registrable Securities under a Registration Statement from which such Losses arise. 

(c) Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any Loss in respect of which indemnity
may be sought pursuant to Section 5(a) or 5(b), such person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder,
notify such other person (the “Indemnifying Party”) in writing of the Loss; provided, however, that the failure by the Indemnified Party to 

  
 -9- 

 
notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the
extent the Indemnifying Party is actually and materially prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be
entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice
from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred
by the Indemnified Party in connection with the defense thereof; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right
to employ separate counsel (but no more than one such separate counsel, in addition to local counsel) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which
indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the reasonable, customary and documented fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of
such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party
(not to be unreasonably withheld, conditioned or delayed), consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of any Losses for which the Indemnified Party seeks indemnification
hereunder if such settlement or judgment includes any non-monetary remedies binding on the Indemnified Party, requires an admission of fault or culpability on the part of the Indemnified Party or does not
include an unconditional release from all liability of the Indemnified Party in respect of such Losses. 
 (d) Contribution. If the
indemnification provided for in the foregoing Sections 5(a) and 5(b) is unavailable to any Indemnified Party in respect of any Loss referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with
the actions or omissions which resulted in such Loss. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the Misstatement relates to information supplied by such
Indemnified Party or such Indemnifying Party (in the case of a Holder, such Misstatement was made in reliance upon and in conformity with information furnished in writing to the Company by such Holder expressly for use therein) and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such Misstatement. The parties hereto agree that it would not be just and equitable if contribution pursuant to this
Section 5(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 this
Section 5(d). The amount paid or payable by an Indemnified Party as a result of any Loss referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5(d), no Investor shall be required to
contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, 

  
 -10- 

 
commissions or taxes) actually received by such Investor from the sale of Registrable Securities which gave rise to such contribution obligation. 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 who was not guilty of such fraudulent misrepresentation. 

6. MISCELLANEOUS. 
 (a) Effective Date.
This Agreement shall be effective as of the Effective Date.

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 1933 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 1933 Act, 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 1933 Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the 1933 Act. Selling
stockholders who are “underwriters” within the meaning of Section 2(11) of the 1933 Act will be subject to the prospectus delivery requirements of the 1933 Act. 

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. 
 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 1934 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 1933 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 1933 Act. 
 We have agreed to indemnify the selling stockholders against liabilities,
including liabilities under the 1933 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 such registration statement or (2) the date on which all of the shares may be sold without restriction pursuant to Rule 144 of the 1933 Act.

 Exhibit 10.3 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of [_______], 2020 between Larimar Therapeutics,
Inc., a Delaware corporation (the “Company”), and [_____] (“Indemnitee”). 
 RECITALS 

WHEREAS, the Company’s Board of Directors (the “Board”) has determined that the increased difficulty in attracting and
retaining directors is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, directors to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is intended to clarify Indemnitee’s entitlement to the maximum indemnity afforded directors under the General
Corporation Law of the State of Delaware (the “DGCL”) and is a supplement to and in furtherance of the provisions calling for indemnification of directors contained in the bylaws or certificate of incorporation of the Company
(collectively and as amended from time to time, the “Charter Documents”) and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder;
and 
 WHEREAS, Indemnitee does not regard the protection available under the Company’s Charter Documents and insurance as adequate in
the present circumstances, and Indemnitee is not willing to serve or continue to serve as a director without adequate protection, and the Company desires Indemnitee to serve in such capacity. 

AGREEMENT 
 NOW,
THEREFORE, in consideration of Indemnitee’s agreement to serve, and to continue his or her service, as a director from and after the date hereof, the parties hereto agree as follows. 

1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law,
as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification
provided in this Section 1(a) if, by reason of his or her Corporate Status (as hereinafter defined), Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other
than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by the Indemnitee, or on his or her behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in
or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

 (b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to
the rights of indemnification provided in this Section 1(b) if, by reason of his or her Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the
right of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such
Proceeding if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such
Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that a court of competent jurisdiction of the State of Delaware
shall determine that such indemnification may be made. 
 (c) Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be
indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly
successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by
dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 2. Additional
Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all
Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his or her behalf if, by reason of his Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant
in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the
Company’s obligations pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections
6 and 7 hereof) to be unlawful. 
 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any Proceeding in which
the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without
requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or proceeding in which
the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

  
 -2- 

 (b) Without diminishing or impairing the obligations of the Company set forth in
Section 3(a), if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined
in such Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the
Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the
transaction or events from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the
relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the
other hand, in connection with the transaction or events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law may require to be considered. The relative fault of
the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall
be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is
active or passive. 
 (c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may
be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 
 (d) To
the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount
incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as
is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such
Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is,
by reason of his or her Corporate Status, a witness, or is made (or asked) to respond to discovery requests, in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred
by Indemnitee or on Indemnitee’s behalf in connection therewith. 

  
 -3- 

 5. Advancement of Expenses. Notwithstanding any other provision of this Agreement,
the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or
statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall
include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances
and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. 
 6. Procedures and
Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of
Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of
such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a
timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless and only to the extent such failure actually and materially prejudices the interests of the Company. 

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a
determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board (other than as set forth in Section 6(b)(iii)(B)): (i) by a
majority vote of the Disinterested Directors (as defined in Section 13 below), even though less than a quorum; (ii) by a committee of Disinterested Directors designated by a majority vote of the Disinterested
Directors, even though less than a quorum; (iii) by Independent Counsel (as defined in Section 13 below) in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, if (A) there are no
Disinterested Directors or if the Disinterested Directors so direct, or (B) a Change of Control (as hereinafter defined) shall have occurred and Indemnitee so requests; or (iv) if so directed by the Board, by the stockholders of the
Company. 
 (c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board, but shall only be an Independent Counsel to
which Indemnitee does not properly object in accordance with the subsequent provisions of this Section 6(c); provided, however, that if a Change of Control shall have occurred, Indemnitee shall select such Independent
Counsel, but only an Independent Counsel to which the Board does not properly object in accordance with the subsequent provisions of this Section 6(c). Within ten (10) days after such written notice of selection shall
have been given, the non-selecting party shall deliver to the selecting party, 

  
 -4- 

 
as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the
requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the
person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that
such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and
not objected to, either the Company or Indemnitee may petition any court of competent jurisdiction in the State of Delaware for resolution of any objection which shall have been made to the selection of Independent Counsel and/or for the appointment
as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under
Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b)
hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) For purposes of this Section 6, “For purposes of this Section 6, “Change of Control” means a change in
control of the Company of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or
not the corporation is then subject to such reporting requirement; provided that, without limitation, such a change in control shall be deemed to have occurred if (i) any Person (as such term is used in Sections 13(d) and 14(d) of the Exchange
Act) is or becomes the Beneficial Owner (as defined in Rule l3d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting
power of the Company’s then outstanding securities; (ii) during any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute
the Board, and any new director whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who
either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a least a majority of the members of the Board; (iii) the effective date of a
merger or consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty one percent (51%) of the combined voting power of the voting securities of the surviving entity outstanding immediately after such
merger or consolidation and with the power to elect at least a majority of the Board or other governing body of such surviving entity; and (iv) the approval by the stockholders of the Company of a complete liquidation of the Company or an
agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets. 

  
 -5- 

 (e) In making a determination with respect to entitlement to indemnification hereunder, the
person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear
and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in
the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (f) Indemnitee
shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise (as defined in Section 13 below), including financial statements, or on information
supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to
Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(f) are satisfied, it shall in any event be presumed that Indemnitee has at
all times acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by
clear and convincing evidence. 
 (g) If the person, persons or entity empowered or selected under Section 6 to
determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be
deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially
misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such sixty (60)-day period may be extended for a
reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate
documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(g) shall not apply if the determination of entitlement to indemnification is to be made by the
stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if
appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special
meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is
made thereat. 
 (h) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to
Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure

  
 -6- 

 
and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and
in good faith in making a determination regarding the Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the
person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless
therefrom. 
 (i) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a
party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation,
settlement of such Proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone seeking to overcome this
presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (j) The termination of any
Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect
the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any
criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. 
 7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not
entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant
to Section 6(b) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within thirty
(30) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within thirty (30) days after a determination has been made that Indemnitee is entitled to indemnification or such
determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent
jurisdiction of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within one hundred eighty (180) days following the date on which Indemnitee first has the right to commence
such proceeding pursuant to this Section 7(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his or her rights under Section 4 of this
Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication. 
 (b) In the event that a determination shall
have been made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all
respects as a de novo trial on the merits and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 

  
 -7- 

 (c) If a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to this
Section 7, seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies
maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably
incurred by Indemnitee in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7
that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any
and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by
Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company,
regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding 
 8.
Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 

(a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at
any time be entitled under applicable law, the Charter Documents, any agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall
limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL,
whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Charter Documents and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the
greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

  
 -8- 

 (b) To the extent that the Company maintains an insurance policy or policies providing
liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other Enterprise that such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance
with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the
Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The
Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 

(c) The Company hereby acknowledges that Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance
provided by third parties (collectively, the “Secondary Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Secondary
Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be
liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Charter and/or Bylaws (or any other agreement between the
Company and Indemnitee), without regard to any rights Indemnitee may have against the Secondary Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Secondary Indemnitors from any and all claims against the Secondary
Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Secondary Indemnitors on behalf of Indemnitee with respect to any claim for which
Indemnitee has sought indemnification from the Company shall affect the foregoing and the Secondary Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of
Indemnitee against the Company. The Company and Indemnitee agree that the Secondary Indemnitors are express third party beneficiaries of the terms of this Section 8(c). At the request of Indemnitee, the Company shall acknowledge in writing its
obligations under this Section 8(c) to any Secondary Indemnitors. 
 (d) Except as provided in paragraph (c) above, in the event of
any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee (other than against the Secondary Indemnitors), and the Indemnitee shall execute all papers required and
take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(e) Except as provided in paragraph (c) above, the Company shall not be liable under this Agreement to make any payment of amounts
otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(f) Except as provided in paragraph (c) above, the Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who
is or was serving at the request of the Company as a director, officer, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement

  
 -9- 

 
of expenses from such other Enterprise (the “Primary Indemnitor”). Any indemnification or advancement of Expenses hereunder to Indemnitee who is or was serving at the request of
the Company as a director, officer, employee or agent of any other Enterprise shall only be in excess of, and shall be secondary to, the indemnification or advancement of Expenses available from the applicable Primary Indemnitor(s) and any
applicable insurance policies. 
 9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the
Company shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for
which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; provided
that the foregoing shall not affect the rights of Indemnitee or the Secondary Indemnitors as set forth in Section 8(c); 
 (b) for an
accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act, or similar provisions of state statutory law or common law; or 

(c) except with respect to a Proceeding relating to enforcement of, or to indemnity under, this Agreement, the Charter Documents, the DGCL or
any insurance policy relating to Indemnitee’s Corporate Status, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against
the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole
discretion, pursuant to the powers vested in the Company under applicable law; provided that this prohibition shall not apply to a counterclaim, cross-claim or third party claim brought in any Proceeding. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee is
a director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of the Company or another Enterprise) and for a period of ten (10) years thereafter, and shall continue thereafter so long
as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of Indemnitee’s Corporate Status, whether or not Indemnitee is acting or serving in any such capacity at
the time any liability or expense is incurred for which indemnification can be provided under this Agreement and regardless of any subsequent amendment to the Charter Documents, the DGCL or any other agreement relating to indemnification of
Indemnitee. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all
or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Security. To the extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time provide
security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the prior
written consent of the Indemnitee. 

  
 -10- 

 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in order
to induce Indemnitee to serve as a director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 
 (c)
The Company shall not seek from a court, or agree to, a “bar order” which would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement. 

13. Definitions. For purposes of this Agreement: 

(a) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or fiduciary of the
Company or of any other Enterprise that such person is or was serving at the express written request of the Company. 
 (b)
“Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee. 

(c) “Enterprise” shall mean the Company and any other corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary. 

(d) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of experts,
witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending,
preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding. Expenses also shall include Expenses incurred
in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including without limitation the
premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against
Indemnitee. 
 (e) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of
corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this
Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding 

  
 -11- 

 
the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest
in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel
against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 

(f) “Proceeding” includes any threatened, pending or completed action, suit, arbitration, alternate dispute resolution
mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in which
Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was a director of the Company, by reason of any action taken by Indemnitee or of any inaction on Indemnitee’s part while acting as a
director of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another Enterprise; in each case whether or not Indemnitee is acting or serving
in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding one initiated by an Indemnitee
pursuant to Section 7 of this Agreement to enforce his rights under this Agreement. 
 14. Severability. The
invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. Further, the invalidity or unenforceability of any provision hereof as to Indemnitee shall in no way affect the
validity or enforceability of any provision hereof as to the other. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In
the event any provision hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

 16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving
any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company
of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay actually materially prejudices the Company. 

17. Notices. All notices and other communications given or made pursuant to this Agreement 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 electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business
day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier,
