 Exhibit 10.4 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is entered into as of
            , 20    , by and between Diamond Offshore Drilling, Inc., a Delaware corporation (the “Company”), and
                     (the “Indemnitee”). 

RECITALS 
 WHEREAS,
competent and experienced persons may be reluctant to serve or continue to serve as directors, managers and/or officers of legal entities or in other capacities unless they are provided with adequate protection through insurance and indemnification
against risks of claims and actions against them arising out of their service to and activities on behalf of any such entity; 
 WHEREAS,
the Board of Directors of the Company (the “Board”) has determined that enhancing the ability of the Company and its direct and indirect subsidiaries to attract and retain qualified persons as directors, managers, and/or officers is
in the best interests of the Company, and that the Company should act to assure such persons that there shall be adequate certainty of protection through insurance and indemnification against risks of claims and actions against them arising out of
their service to and activities on behalf of the Company; 
 WHEREAS, as a supplement to and in furtherance of the Company’s
certificate of incorporation, as the same may be amended and/or restated from time to time (the “Certificate of Incorporation”), the Company’s bylaws, as the same may be amended and/or restated from time to time (the
“Bylaws”), the organizational documents of any direct or indirect subsidiary of the Company (such organizational documents, together with the Certificate of Incorporation and the Bylaws, the “Constituent Documents”)
and the coverage of Indemnitee under the Company’s and/or its subsidiaries’ directors’ and officers’ liability or similar insurance policies from time to time, and to the extent applicable (“D&O Insurance
Policies”), it is reasonable, prudent, desirable and necessary for the Company to contractually obligate itself to indemnify, and to pay in advance expenses and losses on behalf of, directors, managers and officers to the maximum extent
permitted by applicable law, so that highly experienced and capable persons such as the Indemnitee will serve and continue to serve the Company free from undue concern for unpredictable, inappropriate, or unreasonable legal risks and personal
liabilities by reason of the Indemnitee acting in good faith in the performance of the Indemnitee’s duty to the Company; 
 WHEREAS,
this Agreement is not a substitute for, nor does it diminish or abrogate any rights of the Company under the Constituent Documents, the D&O Insurance Policies, or any resolutions or consents adopted related thereto (including any contractual
rights of Indemnitee that may exist under any other agreement as those existing or created as a manner of law or otherwise, both as to actions in Indemnitee’s capacity as an Indemnitee, and as to actions in any other capacity); and 

WHEREAS, the Company desires to have Indemnitee serve as a director, manager, and/or officer of the Company and/or one of its direct or
indirect subsidiaries, as the case may be, and his or her willingness to serve or continue to serve in such capacity is predicated, in substantial part, upon the Company’s willingness to indemnify him or her to the fullest extent permitted by
the laws of the state of Delaware and upon the undertakings set forth in this Agreement. 

 AGREEMENT 

NOW, THEREFORE, in consideration of the Indemnitee’s continued service as a director, manager and/or officer of the Company, the parties
hereto agree as follows: 
 1. Definitions. For purposes of this Agreement: 

(a) A “Change in Control” means a change in control of the Company of a nature that would be required to be reported in
response to Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not the Company is then subject to such reporting requirement; provided, without
limitation, that such a change in control shall be deemed to have occurred if: (A) 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 13d-3 thereunder), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company’s then outstanding securities without the prior approval of
at least two-thirds of the members of the Board in office immediately prior to such acquisition; (B) the Company is a party to a merger, consolidation, sale of assets or other reorganization, or a proxy
contest, as a consequence of which, members of the Board in office immediately prior to such transaction or event constitute less than a majority of the Board thereafter; or (C) during any period of two consecutive years, individuals who at the
beginning of such period constituted the Board (including for this purpose any new director whose election 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 were directors at the beginning of such period) cease for any reason to constitute at least a majority of the Board. 

(b) “Disinterested Director” means a director of the Company who is not or was not a material party to the Proceeding in
respect of which indemnification is sought by the Indemnitee. Disinterested Directors considering or acting on any indemnification matter under this Agreement or under governing corporate law or otherwise may consider or take action as the Board or
may consider or take action as a committee or individually or otherwise. 
 (c) “Expenses” includes, without limitation,
expenses incurred in connection with the defense or settlement of any action, suit, arbitration, alternative dispute resolution mechanism, inquiry, judicial, administrative, or legislative hearing, investigation, or any other threatened, pending, or
completed proceeding, whether brought by or in the right of the Company or otherwise, including any and all appeals, whether of a civil, criminal, administrative, legislative, investigative, or other nature, attorneys’ fees, witness fees and
expenses, fees and expenses of accountants and other advisors, retainers and disbursements and advances thereon, the premium, security for, and other costs relating to any bond (including cost bonds, appraisal bonds, or their equivalents), and any
expenses of establishing a right to indemnification or advancement under this Agreement, but shall not include the amount of judgments, fines, ERISA excise taxes, penalties, or any amounts paid in settlement by or on behalf of the Indemnitee. 

(d) “Independent Counsel” means a law firm or a member of a law firm that neither presently is, nor in the past five years
has been, retained to represent: (i) the Company or the Indemnitee in any manner; or (ii) any other party to the Proceeding giving rise to a request for indemnification hereunder. Notwithstanding the foregoing, the term “Independent
Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing under the law of the State of Delaware, would have a conflict of interest in representing either the Company or the Indemnitee in
an action to determine the Indemnitee’s rights under this Agreement. 
 (e) “Proceeding” means any action, suit,
arbitration, alternative dispute resolution mechanism, inquiry, judicial, administrative, or legislative hearing, investigation, or any other threatened, pending, or completed proceeding, whether brought by or in the right of the Company or
otherwise, including any and all appeals, whether of a civil, criminal, administrative, legislative, investigative, or other nature, to which the Indemnitee was or is a party or is threatened to be made a party or is otherwise involved in by reason
of the fact that the Indemnitee is or was a director, officer, employee, agent, or trustee of the Company or while a director, officer, employee, agent, or trustee of the Company is or was serving at the

  
 2 

 
request of the Company as a director, officer, employee, agent, or trustee of another corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to
an employee benefit plan, or by reason of anything done or not done by the Indemnitee in any such capacity, whether or not the Indemnitee is serving in such capacity at the time any expense, liability, or loss is incurred for which indemnification
or advancement can be provided under this Agreement. 
 2. Service by the Indemnitee. The Indemnitee shall serve and/or continue to
serve as a director, manager, and/or officer of the Company faithfully and to the best of the Indemnitee’s ability so long as the Indemnitee is duly elected or appointed and until such time as the Indemnitee’s successor is elected and
qualified or the Indemnitee is removed as permitted by applicable law or tenders a resignation in writing. For purposes of Sections 2 through 20, “Company” shall include Diamond Offshore Drilling, Inc. and each of its
direct and indirect subsidiaries (whether perpetually in existence, currently in existence, to come into existence, or subsequently dissolved and whether constituting such a subsidiary previously, as of the date hereof, or subsequently). 

3. Indemnification and Advancement of Expenses. The Company shall indemnify and hold harmless the Indemnitee, and shall pay to the
Indemnitee in advance of the final disposition of any Proceeding all Expenses incurred by the Indemnitee in defending any such Proceeding, to the fullest extent authorized by the General Corporation Law of the State of Delaware (the
“DGCL”) as the same exists or may hereafter be amended, all on the terms and conditions set forth in this Agreement. Without diminishing the scope of the rights provided by this Section, the rights of the Indemnitee to
indemnification and advancement of Expenses provided hereunder shall include but shall not be limited to those rights hereinafter set forth, except that no indemnification or advancement of Expenses shall be paid to the Indemnitee: 

(a) to the extent expressly prohibited by applicable law or the Constituent Documents; 

(b) for and to the extent that payment is actually made to the Indemnitee under a valid and collectible insurance policy or under a valid and
enforceable indemnity clause, provision of the Constituent Documents, or agreement of the Company or any other company or other enterprise (and the Indemnitee shall reimburse the Company for any amounts paid by the Company and subsequently so
recovered by the Indemnitee); 
 (c) in connection with an action, suit, or proceeding, or part thereof initiated voluntarily by the
Indemnitee (including claims and counterclaims, whether such counterclaims are asserted by: (i) the Indemnitee; or (ii) the Company in an action, suit, or proceeding initiated by the Indemnitee), except a judicial proceeding or arbitration
pursuant to Section 11 to enforce rights under this Agreement, unless the action, suit, or proceeding, or part thereof, was authorized or ratified by the Board or the Board determines that indemnification or advancement of
Expenses is appropriate; or 
 (d) 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 any similar successor statute. 
 4. Action or
Proceedings Other than an Action by or in the Right of the Company. Except as limited by Section 3 above, the Indemnitee shall be entitled to the indemnification rights provided in this Section if the Indemnitee was or is a party or
is threatened to be made a party to, or was or is otherwise involved in, any Proceeding (other than an action by or in the right of the Company) by reason of the fact that the Indemnitee is or was a director, officer, employee, agent, or trustee of
the Company or while a director, officer, employee, agent, or trustee of the Company is or was serving at the request of the Company as a director, officer, employee, agent, or trustee of another corporation or of a partnership, joint venture,

  
 3 

 
trust, or other enterprise, including service with respect to an employee benefit plan, or by reason of anything done or not done by the Indemnitee in any such capacity. Pursuant to this Section,
the Indemnitee shall be indemnified against all expense, liability, and loss (including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on behalf of the Indemnitee, and Expenses) actually and reasonably incurred by
the Indemnitee 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, and with respect to any criminal Proceeding,
had no reasonable cause to believe his or her conduct was unlawful. 
 5. Indemnity in Proceedings by or in the Right of the Company.
Except as limited by Section 3 above, the Indemnitee shall be entitled to the indemnification rights provided in this Section if the Indemnitee was or is a party or is threatened to be made a party to, or was or is
otherwise involved in, any Proceeding brought by or in the right of the Company to procure a judgment in its favor by reason of the fact that the Indemnitee is or was a director, officer, employee, agent, or trustee of the Company or while a
director, officer, employee, agent, or trustee of the Company is or was serving at the request of the Company as a director, officer, employee, agent, or trustee of another corporation or of a partnership, joint venture, trust, or other enterprise,
including service with respect to an employee benefit plan, or by reason of anything done or not done by the Indemnitee in any such capacity. Pursuant to this Section, the Indemnitee shall be indemnified against all expense, liability, and loss
(including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on behalf of the Indemnitee, and Expenses) actually and reasonably incurred by the Indemnitee in connection with such Proceeding, but only to the extent
permitted by law. 
 6. Indemnification for Costs, Charges, and Expenses of Successful Party. Notwithstanding any limitations of
Sections 3(c), 4, and 5 above, to the extent that the Indemnitee has been successful, on the merits or otherwise, in whole or in part, in defense of any Proceeding, or in defense of any claim, issue, or matter
therein, including, without limitation, the dismissal of any action without prejudice, or if it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that the
Indemnitee is otherwise entitled to be indemnified against Expenses, the Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee in connection therewith. 

7. Contribution in the Event of Joint Liability and Partial Indemnification. 

(a) In respect of any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the
Company shall pay, in the first instance, the entire amount of any expense, liability, or loss (including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on behalf of the Indemnitee, and Expenses) of such 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 Proceeding in which the
Company is jointly liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding Section 7(a), if, for any reason,
Indemnitee shall elect or be required to pay all or any portion of any expense, liability or loss (including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on behalf of the Indemnitee, and Expenses) incurred in
connection with any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall pay to Indemnitee the entire amount of any such expenses, liabilities, or losses in connection with
such Proceeding without requiring Indemnitee to contribute to such payment and the Company hereby 

  
 4 

 
waives and relinquishes any right of contribution it may have against Indemnitee. Indemnitee shall not enter into any settlement of any Proceeding in which the Company is jointly liable with
Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against the Company. 

(c) To the fullest extent permitted by law, the Company will fully indemnify and hold Indemnitee harmless from any claims of contribution
which may be brought by other officers, directors or employees of the Company who may be jointly liable with Indemnitee of any expense, liability or loss (including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on
behalf of the Indemnitee, and Expenses) arising from a proceeding. 
 (d) If the Indemnitee is entitled under any provision of this
Agreement to indemnification by the Company for some or a portion of the expense, liability, and loss (including judgments, fines, ERISA excise taxes, penalties, amounts paid in settlement by or on behalf of the Indemnitee, and Expenses) actually
and reasonably incurred in connection with any Proceeding, or in connection with any judicial proceeding or arbitration pursuant to Section 11 to enforce rights under this Agreement, but not, however, for all of the total
amount thereof, the Company shall nevertheless indemnify the Indemnitee for the portion of such expense, liability, and loss actually and reasonably incurred to which the Indemnitee is entitled. 

8. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the maximum extent permitted by
the DGCL, the Indemnitee shall be entitled to indemnification against all Expenses actually and reasonably incurred by the Indemnitee or on the Indemnitee’s behalf if the Indemnitee appears as a witness or otherwise incurs legal expenses as a
result of or related to the Indemnitee’s service as a director or officer of the Company, in any threatened, pending, or completed action, suit, arbitration, alternative dispute resolution mechanism, inquiry, judicial, administrative, or
legislative hearing, investigation, or any other threatened, pending, or completed proceeding, whether of a civil, criminal, administrative, legislative, investigative, or other nature, to which the Indemnitee neither is, nor is threatened to be
made, a party. 
 9. Determination of Entitlement to Indemnification. To receive indemnification under this Agreement, the Indemnitee
shall submit a written request to the Chief Executive Officer or the Secretary of the Company1. Such request shall include such documentation and information as is reasonably available to the
Indemnitee and reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification (the “Supporting Documentation”). The Secretary of the Company shall promptly advise the Board in writing that
the Indemnitee has requested indemnification. The determination of the Indemnitee’s entitlement to indemnification shall be made by the following person or persons who shall be empowered to make such determination: (a) a majority of the
Disinterested Directors (including by the Disinterested Director, if there is only one); (b) a majority of a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors; (c) Independent Counsel, if a
majority of the Disinterested Directors so directs or there are no Disinterested Directors, in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee; (d) the stockholders of the Company (but only if a majority of
the Disinterested Directors determines that the issue of entitlement to indemnification should be submitted to the stockholders for their determination); (e) in the event that a Change in Control has occurred and the Indemnitee so requests (in
which case the Disinterested Directors shall be deemed to have so directed), by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee; or (f) as provided in
Section 10. In the event the determination of entitlement to indemnification is to be made by Independent Counsel, a majority of the Disinterested Directors shall select 

 

	1 	 Note to Company: Please confirm. 

  
 5 

 
the Independent Counsel, but only an Independent Counsel to which the Indemnitee does not reasonably object; provided, however, that if a Change in Control has occurred or there are
no Disinterested Directors, the Indemnitee shall select such Independent Counsel, but only an Independent Counsel to which the Board does not reasonably object. Upon failure of the Disinterested Directors (or the Indemnitee, in the event a Change in
Control has occurred or there are no Disinterested Directors) to select such Independent Counsel or upon objection by the Indemnitee or Board to the selection of Independent Counsel, such Independent Counsel shall be selected upon application to a
court of competent jurisdiction. The determination of the Indemnitee’s entitlement to indemnification shall be made not later than sixty (60) calendar days after receipt by the Company of the written request therefor together with the
Supporting Documentation, and unless a contrary determination is made, such indemnification shall be paid in full not later than five (5) calendar days after such determination has been made, or is deemed to have been made pursuant to
Section 10. If the person making such determination shall determine that the Indemnitee is entitled to indemnification as to part (but not all) of the application for indemnification, such person shall reasonably prorate
such partial indemnification among the claims, issues, or matters at issue at the time of the determination. 
 10. Presumptions and
Effect of Certain Proceedings. 
 (a) Except as otherwise expressly provided in this Agreement, the Indemnitee shall be presumed to be
entitled to indemnification upon submission of a request for indemnification together with the Supporting Documentation, and thereafter in any determination or review of any determination, and in any suit, arbitration or adjudication, the Company
shall have the burden of proof to overcome that presumption, including the burden of proof that the Indemnitee has not met the standard of conduct described above and also the burden of proof on any of the issues which may be material to a
determination that the Indemnitee is not entitled to indemnification. 
 (b) 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, of itself, adversely affect the right of the Indemnitee to indemnification or create any presumption with respect
to any standard of conduct or belief or any other matter which might form a basis for a determination that the Indemnitee is not entitled to indemnification. 

(c) With regard to the right to indemnification for Expenses: (i) if and to the extent that the Indemnitee has been successful on the
merits or otherwise, in whole or in part, in defense of any Proceeding; (ii) if a Proceeding was terminated without a determination of liability on the part of the Indemnitee with respect to any claim, issue, or matter therein or without any
payments in settlement or compromise being made by the Indemnitee with respect to a claim, issue, or matter therein; or (iii) if and to the extent that the Indemnitee was not a party to the Proceeding, the Indemnitee shall be deemed to be
entitled to indemnification, which entitlement shall not be defeated or diminished by any determination which may be made pursuant to Section 9. 

(d) The Indemnitee shall be presumptively entitled to indemnification in all respects for any act, omission, or conduct taken or occurring
which (whether by condition or otherwise) is required, authorized, or approved by any order issued or other action by any commission or governmental body pursuant to any federal statute or state statute regulating the Company or any of its
subsidiaries by reason of its status as a public utility or public utility holding company or by reason of its activities as such. To the extent permitted by law, the presumption shall be conclusive on all parties with respect to acts, omissions, or
conduct of the Indemnitee if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company or its subsidiaries. No presumption adverse to the Indemnitee shall be drawn with
respect to any act, omission, or conduct of the Indemnitee if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company or its subsidiaries taken or occurring in the
absence of, or inconsistent with, any order issued or action by any commission or governmental body.

 11. Remedies of the Indemnitee in Cases of Determination Not to Indemnify or to Advance
Expenses; Right to Bring Suit. 
 (a) In the event that a determination is made pursuant to Section 9 that the
Indemnitee is not entitled to indemnification hereunder, or if payment is not timely made following a determination of entitlement to indemnification pursuant to Sections 9 or 10, or if an advancement of Expenses is
not timely made pursuant to Section 16, the Indemnitee may at any time thereafter seek an adjudication of his or her entitlement to payment either, at the Indemnitee’s sole option, in an appropriate court of the State of Delaware or
any other court of competent jurisdiction. Any such suit or arbitration shall be de novo and the Indemnitee shall not be prejudiced by reason of such adverse determination. The Company shall not oppose the Indemnitee’s right to seek any
such adjudication or award in arbitration. 
 (b) In any suit or arbitration brought by the Indemnitee to enforce a right to indemnification
or to an advancement of Expenses hereunder, or in any suit brought by the Company to recover an advancement of Expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such
advancement of expenses, under this Section 11 or otherwise shall be on the Company. Neither the failure of the Company (including the Disinterested Directors, a committee of Disinterested Directors, Independent Counsel, or
its stockholders) to have made a determination prior to the commencement of a suit or arbitration regarding whether indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the standard of conduct described
above, nor an actual determination by the Company (including the Disinterested Directors, a committee of Disinterested Directors, Independent Counsel, or its stockholders) that the Indemnitee has not met the standard of conduct described above shall
create a presumption that the Indemnitee has not met the standard of conduct. Neither a failure to make such a determination of entitlement nor an adverse determination of entitlement to indemnification shall be a defense of the Company in a suit or
arbitration brought by the Indemnitee or a suit by or on behalf of the Company relating to indemnification or create any presumption that the indemnitee has not met the standard of conduct described above or is otherwise not entitled to
indemnification. In any suit brought by the Company to recover an advancement of Expenses pursuant to the terms of an undertaking, the Company shall be entitled to recover such Expenses upon a final judicial decision of a court of competent
jurisdiction from which there is no further right to appeal that the Indemnitee has not met the standard of conduct described above. 
 (c)
If a determination shall have been made or deemed to have been made, pursuant to Sections 9 or 10, that the Indemnitee is entitled to indemnification, the Company shall be obligated to pay the amounts constituting such
indemnification within five (5) calendar days after such determination has been made or deemed to have been made, as required by Section 9, and shall be conclusively bound by such determination, unless: (i) the Indemnitee
misrepresented or failed to disclose a material fact in making the request for indemnification or in the Supporting Documentation; or (ii) such indemnification is prohibited by law, in either case as ultimately determined by final judicial
decision of a court of competent jurisdiction from which there is no further right to appeal, or, at the Indemnitee’s sole option, arbitration as provided in Section 11. Notwithstanding the foregoing, the Company may
bring suit, in an appropriate court in the State of Delaware or any other court of competent jurisdiction, contesting the right of the Indemnitee to receive Indemnification hereunder due to the occurrence of a circumstance described in clause
(i) above or a prohibition of law (both of which are herein referred to as a “Disqualifying Circumstance”). In any such suit or arbitration, whether brought by the Indemnitee or the Company, the Indemnitee shall be entitled to
indemnification unless the Company can satisfy the burden of proof that indemnification is prohibited by reason of a Disqualifying Circumstance. 

  
 7 

 (d) the Company shall be precluded from asserting in any suit or arbitration commenced
pursuant to Section 11 that the procedures and presumptions or any other provisions of this Agreement are not valid, binding, and enforceable and shall stipulate in any such court or before any such arbitrator or
arbitrators that the Company is bound by all the provisions of this Agreement. 
 12.
Non-Exclusivity of Rights. The rights to indemnification and to the advancement of Expenses provided by this Agreement shall not be deemed exclusive of any other right that the Indemnitee may now or
hereafter acquire under any applicable law, agreement, vote of stockholders or Disinterested Directors, the Constituent Documents, any D&O Insurance Policy, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision
hereof limits or restricts any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee 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 Constituent Documents, the D&O Insurance Policies and this Agreement, it is the intent of the parties hereto that Indemnitee enjoy by this Agreement
the greater benefits so afforded by such change. To the extent that a change in the DGCL, whether by statute or judicial decision, narrows the indemnification than would be afforded currently under the Constituent Documents and this Agreement, it is
the intent of the parties hereto that such change, to the extent not otherwise prohibited by such law, shall have no effect on this Agreement or the parties’ rights and obligations hereunder. 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 Indemnitee is free to
proceed under any of the rights available to him or her. 
 13. Expenses to Enforce Agreement. In the event that the Indemnitee seeks
a judicial adjudication of or an award in arbitration to enforce his or her rights under, or to recover damages for breach of, this Agreement, or is otherwise involved in any adjudication or arbitration with respect to his or her rights under this
Agreement, the Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any Expenses actually and reasonably incurred by the Indemnitee in connection with such adjudication or award in arbitration
(including, but not limited to, any appellate proceedings) if the Indemnitee prevails in such judicial adjudication or arbitration, to the fullest extent permitted by law. If it shall be determined in such judicial adjudication or arbitration that
the Indemnitee is entitled to receive part but not all of the indemnification or advancement of Expenses sought, the expenses incurred by the Indemnitee in connection with such judicial adjudication or arbitration shall be prorated accordingly. In
any suit brought by the Company to recover an advancement of Expenses pursuant to the terms of an undertaking, the Company shall pay all Expenses actually and reasonably incurred by the Indemnitee in connection with such suit to the extent the
Indemnitee has been successful, on the merits or otherwise, in defense of such suit, to the fullest extent permitted by law. 
 14.
Continuation of Indemnity. All agreements and obligations of the Company contained herein shall continue during the period the Indemnitee is a director, officer, employee, agent, or trustee of the Company or while a director, officer,
employee, agent, or trustee is serving at the request of the Company as a director, officer, employee, agent, or trustee of another corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to an
employee benefit plan, and shall continue thereafter with respect to any possible claims based on the fact that the Indemnitee was a director, officer, employee, agent, or trustee of the Company or was serving at the request of the Company as a
director, officer, employee, agent, or trustee of another corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to an employee benefit plan. This Agreement shall be binding upon all successors and
assigns of the Company (including any transferee of all or substantially all of its assets and any successor by merger or operation of law) and shall inure to the benefit of the Indemnitee’s heirs, executors, and administrators.

 15. Notification; Selection of Counsel. Promptly after receipt by the Indemnitee of
notice of any Proceeding, the Indemnitee shall, if a request for indemnification or an advancement of Expenses in respect thereof is to be made against the Company under this Agreement, notify the Company in writing of the commencement thereof; but
the omission to so notify the Company shall not relieve it from any liability or obligation that it may have to the Indemnitee. 
 (a)
Except as otherwise provided in Section 15(b), the Company may, if appropriate, assume the defense of a Proceeding, with legal counsel approved by the Indemnitee, which approval shall not be unreasonably withheld. With respect to a
Proceeding, the Company may satisfy its obligations under this Agreement by paying for single counsel for a group of indemnitees, and legal counsel may represent both the Indemnitee and the Company (and/or any other indemnitees entitled to receive
advancement of Expenses or indemnification from the Company with respect to such matter), in each case unless: (i) the Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and the Indemnitee or
any other such indemnitees; or (ii) under the applicable standards of professional conduct then prevailing, such legal counsel would have a conflict of interest. Any counsel retained in accordance with the preceding sentence shall be approved
by the Indemnitee (and any other such indemnitees), by majority vote of indemnitees who are directors, president, or executive vice presidents of the Company, which approval shall not be unreasonably withheld. If the D&O Insurance Policies, or
other insurance policies, have a panel counsel requirement that may cover the matter for which advancement of Expenses or indemnification is sought, then such counsel shall be selected from among the panel counsel or other counsel approved by the
insurers, unless the Company waives such requirement in writing. 
 (b) In any Proceeding brought by or in the right of the Company to
procure a judgment in its favor, the Indemnitee (and/or any other indemnitees entitled to receive advancement of Expenses or indemnification from the Company with respect to such matter) shall be entitled to select single counsel of their choice to
represent such group of indemnitees, and such counsel shall represent the group of indemnitees unless: (i) the Indemnitee or another indemnitee shall have reasonably concluded that there may be a conflict of interest between the Indemnitee or
any other such indemnitees; or (ii) under the applicable standards of professional conduct then prevailing, such legal counsel would have a conflict of interest. Counsel for the group of indemnitees shall be selected and approved by majority
vote of the indemnitees who are directors, president, or executive vice presidents of the Company, which approval shall not be unreasonably withheld. If the D&O Insurance Policies, or other insurance policies, have a panel counsel requirement
that may cover the matter for which advancement of Expenses or indemnification is sought, then such counsel shall be selected from among the panel counsel or other counsel approved by the insurers, unless the Company waives such requirement in
writing. The Company shall not be entitled to assume the defense of any Proceeding brought by or in the right of the Company to procure a judgment in its favor. 

(c) Notwithstanding any other provision of this Agreement, the Indemnitee shall have the right to employ the Indemnitee’s own counsel in
any Proceeding, but, except as set forth in Sections 15(a) or 15(b) hereof, the fees and expenses of such counsel shall be at the expense of the Indemnitee unless: (i) there is a conflict of interest as described above; or
(ii) the employment of counsel by the Indemnitee has been authorized by the Company. 
 (d) Notwithstanding any other provision of this
Agreement, the Company shall not be liable to indemnify the Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without the Company’s written consent. The Company shall not settle any Proceeding in any
manner that would impose any penalty or limitation on or disclosure obligation with respect to the Indemnitee without the Indemnitee’s written consent, or that would directly or indirectly constitute or impose any admission or acknowledgment of
fault or culpability with respect to the Indemnitee without the Indemnitee’s written consent. Neither the Company nor the Indemnitee shall unreasonably withhold its consent to any proposed settlement. 

  
 9 

 (e) Advancement of Expenses. All Expenses incurred by the Indemnitee in defending any
Proceeding described in Sections 4 or 5 shall be paid by the Company in advance of the final disposition of such Proceeding at the request of the Indemnitee. To receive an advancement of Expenses under this
Agreement, the Indemnitee shall submit a written request to the Chief Executive Officer or the Secretary of the Company. Such request shall reasonably evidence the Expenses incurred or about to be incurred by the Indemnitee and, if required by law
at the time of such advancement, shall include or be accompanied by an undertaking by or on behalf of the Indemnitee to repay the amounts advanced if it shall ultimately be determined, by final judicial decision of a court of competent jurisdiction
from which there is no further right to appeal, that the Indemnitee is not entitled to be indemnified for such Expenses by the Company as provided by this Agreement or otherwise. The Indemnitee’s undertaking to repay any such amounts is not
required to be secured. Each such advancement of Expenses shall be made within twenty (20) calendar days after receipt by the Company of such written request. The Indemnitee’s entitlement to Expenses under this Agreement shall include
those incurred in connection with any action, suit, or proceeding by the Indemnitee seeking an adjudication or award in arbitration pursuant to Section 11 of this Agreement (including the enforcement of this provision) to
the extent the court or arbitrator shall determine that the Indemnitee is entitled to an advancement of Expenses hereunder. 
 16.
Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal, or unenforceable for any reason whatsoever: (a) the validity, legality, and enforceability of the remaining provisions of this Agreement
(including, without limitation, all portions of any paragraphs of this Agreement containing any such provision held to be invalid, illegal, or unenforceable, that are not by themselves invalid, illegal, or unenforceable) shall not in any way be
affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Agreement (including, without limitation, all portions of any paragraph of this Agreement containing any such provision held to be invalid, illegal, or
unenforceable, that are not themselves invalid, illegal, or unenforceable) shall be construed so as to give effect to the intent of the parties that the Company provide protection to the Indemnitee to the fullest enforceable extent.

(a) Until the earlier of (i) three years following the Effective Date of the Initial Shelf Registration Statement and (ii) for so
long as any Registrable Securities requested by the Requesting Group to be included in the Initial Shelf Registration Statement (the “Requested Securities”) constitute Registrable Securities (the “Registration Expiration
Date”), the Company shall use its commercially reasonably efforts to (A) maintain its eligibility to register the Requested Securities on Form S-3 and (B) if the Company is unable to
maintain its eligibility to register the Requested Securities on Form S-3, maintain its ability to meet the eligibility requirements to register the Requested Securities on Form

(iii) if the Company is not a Smaller Reporting Company eligible to incorporate by reference pursuant to Item 12(b) of Form S-1, promptly file a Registration Statement on Form S-1 and use its commercially reasonable efforts to cause such Registration Statement to be declared effective and for so long as any of the Requested Securities covered by such Registration Statement on Form S-1 constitute Registrable Securities, file any supplements to the Registration Statement or post-effective amendments required to be filed by applicable law in order to incorporate into such Registration Statement
any Current Reports on Form 8-K necessary or required to be filed by applicable law, any Quarterly Reports on Form 10-Q or any Annual Reports on Form 10-K filed by the Company with the Commission, or any other information necessary so that (x) such Registration Statement shall not include any untrue statement of material fact or omit to state any material
fact necessary in order to make the statements therein not misleading, and (y) the Company complies with its obligations under Item 512(a)(1) of Regulation S-K; provided, however, that these
obligations remain subject to the Company’s rights under Section 5 and the Holders’ obligations under Section 4 and Section 11. 

  
 6 

 4. Holders’ Obligations. No Holder shall be entitled to sell any
Registrable Securities pursuant to this Agreement, unless such Holder has timely furnished the Company with all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not misleading
and any other information regarding such Holder and the distribution of its Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and
warranty by such Holder that the information of such Holder furnished in writing by or on behalf of such Holder, including in such Holder’s Selling Stockholder Questionnaire, to the Company does not include an untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements furnished by such Holder, in the light of the circumstances under which they were made, not misleading. 

5. Blackout Periods. 

(a) Notwithstanding anything to the contrary herein— 

(A) the Company shall be entitled to postpone the filing or effectiveness of, or, at any time after a Registration Statement
has been declared effective by the Commission suspend the use of, a Registration Statement (including the Prospectus included therein) if in the good faith judgment of the Board, such registration, offering or use would reasonably be expected to
materially affect in an adverse manner or materially interfere with any bona fide material financing of the Company or any material transaction under consideration by the Company or would require the disclosure of information that has not been, and
is not otherwise required to be, disclosed to the public and the premature disclosure of which would reasonably be expected, in the good faith judgment of the Board, to materially affect the Company in an adverse manner; and 

(B) at any time after a Registration Statement has been declared effective by the Commission and there is no duty to disclose
under applicable law, the Company may delay the disclosure of material non-public information concerning the Company if the disclosure of such information at the time would, in the good faith judgment of the
Board, reasonably be expected to materially and adversely affect the Company (the period of a postponement or suspension as described in clause (A) and/or a delay described in this clause (B), a “Blackout Period”). 

(b) The Company shall promptly (i) notify the Holders in writing of the existence of the event or material
non-public information giving rise to a Blackout Period (provided that the Company shall not disclose the content of such material non-public information to any
Holder, without the express consent of such Holder) or the need to file a post-effective amendment, as applicable, and the date on which such Blackout Period will begin, (ii) use commercially reasonable efforts to terminate a Blackout Period as
promptly as practicable and (iii) notify the Holders in writing of the date on which the Blackout Period ends. 
 (c) A Blackout Period
may not be called by the Company more than three (3) times in any period of twelve (12) consecutive months, and the duration of all Blackout Periods shall not exceed ninety (90) days in any period of twelve (12) consecutive
months. For purposes of determining the length of a Blackout Period, the Blackout Period shall be deemed to begin on and include the date the Holders receive the notice referred to in clause (i) of Section 5(b) and
shall end on and include the later of the date the Holders receive the notice referred to in clause (iii) of Section 5(b) and the date referred to in such notice. In the event the Company declares a Blackout Period,
the Registration Expiration Date shall be deemed to be extended by the number of days an effective Registration Statement is unavailable. 

  
 7

registration under the Securities Act as provided in Section 2(a) of this Agreement, the Company shall use its commercially reasonable efforts to:

its commercially reasonable efforts to cause such Registration Statement to become and remain effective, subject to the limitations contained herein;

Registration Statement until such time as all of such Registrable Securities have ceased to constitute Registrable Securities, subject to the limitations contained herein; provided that to the extent the Commission requires such Registration
Statement to include an offering price for the Registrable Securities, Holders whose securities are covered by the Registration Statement will provide the offering price, which shall be determined by Holders beneficially owning a majority of such
Registrable Securities, to the Company and the Company shall, as soon as possible and, in any event, within two Business Days, amend such Registration Statement through a prospectus supplement or otherwise to include such offering price; 

(c) (i) before filing a Registration Statement or Prospectus or any amendments or supplements thereto, at the Company’s

such other documents reasonably requested by such Holders (which may be furnished by email), and afford Counsel to the Holders a reasonable opportunity to review and comment on such documents; and (ii) in connection with the preparation and
filing of each such Registration Statement pursuant to this Agreement, (A) upon reasonable advance notice to the Company, give each of the foregoing such reasonable access to all financial and other records, corporate documents and properties
of the Company as shall be necessary, in the reasonable opinion of Counsel to the Holders, to conduct a reasonable due diligence investigation for purposes of the Securities Act and Exchange Act and (B) upon reasonable advance notice to the
Company and during normal business hours and for reasonable periods, provide such reasonable opportunities to discuss the business of the Company with its officers, directors and the independent public accountants who have certified its financial
statements as shall be necessary, in the reasonable opinion of Counsel to the Holders, to conduct a reasonable due diligence investigation for purposes of the Securities Act and the Exchange Act;

defined under Rule 433 promulgated under the Securities Act), all exhibits and other documents filed therewith and such other documents as such seller may reasonably request including in order to facilitate the disposition of the Registrable

included in such Registration Statement, as then in effect, 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 the light of
the circumstances under which they were made and for which the Company believes in its reasonable good faith judgment it must suspend the use of the Registration Statement until an amendment or supplement to such Registration Statement necessary to
keep such Registration Statement effective and 

  
 9 

 
to comply with the provisions of the Securities Act and the Exchange Act may be filed (which the Company shall use its commercially reasonable efforts to file and have declared effective as soon
as possible), at the written request of any such Holder, promptly prepare and furnish to it a copy of a supplement to or an amendment (which may be furnished by email) of such Prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such Prospectus, as supplemented or amended, 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 the light of the circumstances under which they were made; 
 (i) notify the Holders of Registrable Securities

agency or authority having jurisdiction over the offering of Registrable Securities, and make available to its stockholders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months, but not
more than eighteen (18) months, beginning with the first (1st) full calendar month after the Effective Date of such Registration Statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder and which requirement will be deemed satisfied if the Company timely files complete and accurate information on Form

Act; 
 (l) provide and cause to be maintained a transfer agent and registrar for the Registrable Securities included in a
Registration Statement no later than the Effective Date thereof; 
 (m) enter into such agreements and take such other
actions as the Holders beneficially owning a majority of the Registrable Securities included in a Registration Statement shall reasonably request in order to expedite or facilitate the disposition of such Registrable Securities, including customary
indemnification; 
 (n) cooperate with the Holders of Registrable Securities included in a Registration Statement to
facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends, and enable such Registrable Securities to be in such share amounts and registered in such names as
the Holders beneficially owning a majority of the Registrable Securities being offered for sale, may reasonably request at least three (3) Business Days prior to any sale of Registrable Securities; and 

  
 10 

 (o) otherwise use its commercially reasonable efforts to take all other
steps necessary to effect the registration of such Registrable Securities contemplated hereby. 
 In addition, at least ten (10) Business Days prior to
the first anticipated filing date of a Registration Statement for any registration under this Agreement, the Company will notify each Holder of the information the Company requires from that Holder, including any update to or confirmation of the
information contained in the Selling Stockholder Questionnaire, if any, which shall be fully completed and delivered to the Company promptly upon request and, in any event, within five (5) Business Days prior to the applicable anticipated
filing date. Each Holder further agrees that it shall not be entitled to be named as a selling stockholder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless such Holder has
returned to the Company a fully completed and signed Selling Stockholder Questionnaire and responses to any requests for further information as described in the previous sentence. If a Holder of Registrable Securities returns a Selling Stockholder
Questionnaire or a request for further information, in either case, after its respective deadline, the Company shall be permitted to exclude such Holder from being a selling stockholder in the Registration Statement or any pre-effective or post-effective amendment thereto. Each Holder acknowledges and agrees that the information in the Selling Stockholder Questionnaire or request for further information as described in this
Section 6 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. 

7. Registration Expenses. All fees and expenses incident to the Company’s performance of or compliance with its obligations under
this Agreement shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all

Holder intends to make sales of Registrable Securities with the Financial Industry Regulatory Authority (“FINRA”) pursuant to the FINRA Rule 5110, so long as the broker is receiving no more than a customary brokerage commission in
connection with such sale, (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for
the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by

out-of-pocket expenses of Counsel to the Holders in connection with the filing or amendment of any Registration Statement, Prospectus or free writing prospectus

 11 

 8. Indemnification. 

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold
harmless each Holder, the officers, directors, agents, partners, members, investment manager, managers, stockholders, Affiliates and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against
any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), to which any of
them may become subject, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of Prospectus or in any amendment or supplement
thereto or in any preliminary Prospectus or (ii) any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of Prospectus or
supplement thereto, in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based
upon information regarding such Holder furnished in writing (including, without limitation, in a Selling Stockholder Questionnaire furnished by such Holder) to the Company by such Holder expressly for use therein, or to the extent that such
information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was provided by such Holder in writing expressly for use in the Registration Statement, such Prospectus or such form of Prospectus
or in any amendment or supplement thereto, or (B) in the case of an occurrence of an event of the type specified in Section 6(h), related to the use by a Holder of an outdated or defective Prospectus after the Company
has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated and defined in Section 13(c) below, but only if and to the extent that
following the receipt of the Advice the misstatement or omission giving rise to such Loss would have been corrected, and provided, further that such indemnity shall not be available to any person to the extent that such Losses resulted
from or are caused by willful misconduct or gross negligence of such person. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as defined in
Section 8(c)), shall survive the transfer of the Registrable Securities by the Holders, and shall be in addition to any liability which the Company may otherwise have. 

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its respective
directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such
controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any
Prospectus, or any form of Prospectus, or in any amendment or supplement thereto or in any preliminary Prospectus, or 

  
 12 

 
arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, or any
form of Prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading (i) to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding such
Holder furnished in writing (including, without limitation, in a Selling Stockholder Questionnaire furnished by such Holder) to the Company by such Holder expressly for use therein, (ii) to the extent, but only to the extent, that such
information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was provided by such Holder in writing (including, without limitation, in a Selling Stockholder Questionnaire furnished by such
Holder) expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (iii) in the case of an occurrence of an event of the type specified in
Section 6(h), to the extent, but only to the extent, related to the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or
defective and prior to the receipt by such Holder of the Advice contemplated in Section 13(c), but only if and to the extent that following the receipt of the Advice the misstatement or omission giving rise to such Loss
would have been corrected. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as defined in Section 8(c)), shall survive the transfer of the
Registrable Securities by the Holders, and shall be in addition to any liability which the Holder may otherwise have. 
 (c) Conduct of
Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity
is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of
all reasonable fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this
Agreement, except (and only) to the extent that such failure shall have materially and adversely prejudiced the Indemnifying Party. 
 An
Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless:
(1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such
Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by
counsel that in the reasonable judgment of such counsel a conflict of interest exists if the same counsel were to represent such Indemnified Party and the Indemnifying Party; provided, that the Indemnifying Party shall not be liable for the
reasonable and documented fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of 

  
 13 

 
any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party shall, without the prior written consent
of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are
the subject matter of such Proceeding. 
 Subject to the terms of this Agreement, all reasonable and documented fees and expenses of the
Indemnified Party (including reasonable and documented 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 8(c))
shall be paid to the Indemnified Party, as incurred, with reasonable promptness after receipt of written notice thereof to the Indemnifying Party; 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 such Indemnified Party is finally judicially determined to not be entitled to indemnification hereunder. The failure to deliver written notice to the Indemnifying Party within a
reasonable time of the commencement of any such action shall not relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 8, except to the extent that the Indemnifying Party is materially
and adversely prejudiced in its ability to defend such action. 
 (d) Contribution. If a claim for indemnification under
Section 8(a) or (b) is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless for any Losses, then each 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 Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions,
statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall 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 of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified
Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. 

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were
determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this
Section 8(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities subject to
the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

  
 14 

 9. Rule 144. With a view to making available to the Holders of
Registrable Securities the benefits of Rule 144 promulgated under the Securities Act and other rules and regulations of the Commission that may at any time permit a Holder of Registrable Securities to sell securities of the Company without
registration, until such time as when no Registrable Securities remain outstanding, the Company covenants that it will (i) if it is subject to the reporting requirement of 13 or 15(d) of the Exchange act, file in a timely manner all reports and
other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder or (ii) if it is not subject to the reporting requirement of 13 or 15(d) of the Exchange Act,
make available information necessary to comply with Rule 144, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, 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 exemption provided by (x) Rule 144 (if available with respect to resales of the Registrable Securities), as such rule may be amended from
time to time or (y) any similar rules or regulations adopted by the Commission. Upon the reasonable request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with
such information requirements, and, if not, the specific reasons for non-compliance. 
 10.
Transfer of Registration Rights. Any Holder may freely assign its rights hereunder on a pro rata basis in connection with any sale, transfer, assignment, or other conveyance (any of the foregoing, a “Transfer”) of Registrable
Securities to any transferee or assignee; provided that all of the following additional conditions are satisfied: (a) such Transfer is effected in accordance with applicable securities laws; (b) such transferee or assignee agrees in
writing to become subject to the terms of this Agreement; and (c) the Company is given written notice by such Holder of such Transfer, stating the name and address of the transferee or assignee and identifying the Registrable Securities with
respect to which such rights are being transferred or assigned; and further provided, that (i) any rights assigned hereunder shall apply only in respect of the Registrable Securities that are Transferred and not in respect of any other
securities that the transferee or assignee may hold and (ii) any Registrable Securities that are Transferred may cease to constitute Registrable Securities following such Transfer in accordance with the terms of this Agreement. 

11. Cooperation. It shall be a condition of each Holder’s rights under Section 2 and
Section 3 that such Holder cooperate with the Company by entering into any undertakings and taking such other action relating to the conduct of the proposed offering which the Company or the underwriters may reasonably
request as being necessary to insure compliance with federal and state securities laws and the rules or other requirements of FINRA or which are otherwise customary and which the Company or the underwriters may reasonably request to effectuate the
offering. 
 12. Further Assurances. Each of the parties hereto shall execute all such further instruments and documents and take all
such further action as any other party hereto may reasonably require in order to effectuate the terms and purposes of this Agreement. 
 13.
Miscellaneous. 
 (a) Remedies. Any Person having rights under any provision of this Agreement shall be entitled to enforce
such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages may not be an adequate remedy
for any breach 

  
 15 

 
of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or other security) for
specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this Agreement. 
 (b)
Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable
Securities pursuant to any Registration Statement and shall sell the Registrable Securities only in accordance with a method of distribution described in each Registration Statement. 

(c) Discontinued Disposition. Each Holder agrees that, upon receipt of a notice from the Company of the occurrence of a Blackout
Period, such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it
may have been supplemented or amended) may be resumed. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. 

(d) Preservation of Rights. The Company shall not grant to third parties any registration rights of the same nature as the registration
rights granted hereunder on terms which are more favorable than or inconsistent with the terms of the rights granted hereunder unless any such more favorable terms are concurrently added to the rights granted hereunder. 

(e) No Inconsistent Agreements. The Company shall not hereafter enter into any agreement with respect to its securities which is
inconsistent with or violates the rights granted to the Holders in this Agreement. 
 (f) Amendments and Waivers. The provisions of
this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, or waived unless the same shall be in writing and signed by the Company and Holders holding at least a majority of the then outstanding
Registrable Securities; provided, however, that any party may give a waiver as to itself and that any Person may become a party to this Agreement by executing and delivering a joinder in accordance with this Agreement; provided further,
however that no amendment, modification, supplement, or waiver that disproportionately and adversely affects, alters, or changes the interests of any Holder shall be effective against such Holder without the prior written consent of such Holder;
provided further, however that the definition of “Holders” in Section 1 may not be amended, modified or supplemented, or waived unless in writing and signed by all the signatories to this Agreement; and
provided further that the waiver of any provision with respect to any Registration Statement or offering may be given by Holders holding at least a majority of the then outstanding Registrable Securities entitled to participate in such
offering or, if such offering shall have been commenced, having elected to participate in such offering. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the
rights of certain Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of a majority of the Registrable Securities to which such waiver or consent relates; provided, however, that
the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. No waiver of any terms or conditions 

  
 16 

 
of this Agreement shall operate as a waiver of any other breach of such terms and conditions or any other term or condition, nor shall any failure to enforce any provision hereof operate as a
waiver of such provision or of any other provision hereof. No written waiver hereunder, unless it by its own terms explicitly provides to the contrary, shall be construed to effect a continuing waiver of the provisions being waived and no such
waiver in any instance shall constitute a waiver in any other instance or for any other purpose or impair the right of the party against whom such waiver is claimed in all other instances or for all other purposes to require full compliance with
such provision. The failure of any party to enforce any provision of this Agreement shall not be construed as a waiver of such provision and shall not affect the right of such party thereafter to enforce each provision of this Agreement in
accordance with its terms. 
 (g) Notices. Any notice or other communication required or which may be given hereunder shall be in
writing and shall be sent by certified or regular mail, by private national courier service (return receipt requested, postage prepaid), by personal delivery, by electronic mail or by facsimile transmission. Such notice or communication shall be
deemed given (i) if mailed, two days after the date of mailing, (ii) if sent by national courier service, one Business Day after being sent, (iii) if delivered personally, when so delivered, (iv) if sent by electronic mail, on
the Business Day such electronic mail is transmitted, or (v) if sent by facsimile transmission, on the Business Day such facsimile is transmitted, in each case as follows:

 (h) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns (including any trustee in bankruptcy). In addition, and whether or not any express assignment shall have been made, the provisions of this
Agreement which are for the benefit of the Holders of Registrable Securities (or any portion thereof) as such shall be for the benefit of and enforceable by any subsequent holder of any Registrable Securities (or of such portion thereof);
provided, that such subsequent holder of Registrable Securities shall be required to execute a joinder to this Agreement in form and substance reasonably satisfactory to the Company agreeing to be bound by its terms. No assignment or
delegation of this Agreement by the Company, or any of the Company’s rights, interests or obligations hereunder, shall be effective against any Holder without the prior written consent of such Holder.

or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same Agreement.

(k) Governing Law; Venue. This Agreement and the rights and obligations of the parties hereunder shall be construed and enforced in
accordance with, and the rights of the parties shall be governed by, the laws of the State of New York, without giving effect to any conflict of laws principles that would require the application of the laws of any other jurisdiction. Each of the
parties hereunder irrevocably agrees that any legal action, suit or proceeding arising out of or relating to this Agreement brought by any party hereunder shall be brought and determined in any state court located in The City and County of New York,
and each of the parties hereunder hereby irrevocably submits to the exclusive jurisdiction of the aforesaid court for itself and with respect to its property, generally and unconditionally, with regard to any such proceeding arising out of or
relating to this Agreement. Each of the parties agrees not to commence any proceeding relating to this Agreement except in any state court located in The City and County of New York, other than proceedings in any court of competent jurisdiction to
enforce any judgment, decree or award rendered by the aforesaid court. Each of the parties further agrees that notice as provided in Section 13(g) shall constitute sufficient service of process and the parties further waive
any argument that such service is insufficient. The parties hereto consent to and agree to submit to the jurisdiction of any of the courts specified herein and agree to accept service of process to vest personal jurisdiction over them in any of
these courts. 
 (l) Waiver of Jury Trial. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY (I) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 13(l). 

  
 18 

 (m) Severability. If any provision of this Agreement, or the application of any such
provision to any person or circumstance, shall be held invalid or unenforceable in whole or in part, such invalidity or unenforceability shall attach only to such provision or circumstance thereof and any remaining part of such provision hereof, and
this Agreement, shall continue in full force and effect to the furthest extent permitted by applicable law. Upon any such determination of invalidity, the parties hereunder shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible. 
 (n) Descriptive Headings; Interpretation; No Strict Construction. The
descriptive headings of this Agreement are inserted for convenience only and do not constitute a substantive part of this Agreement. Whenever required by the context, any pronoun used in this Agreement shall include the corresponding masculine,
feminine or neuter forms, and the singular forms of nouns, pronouns, and verbs shall include the plural and vice versa. Reference to any agreement, document, or instrument means such agreement, document, or instrument as amended or otherwise
modified from time to time in accordance with the terms thereof, and, if applicable, hereof. The words “include”, “includes” or “including” in this Agreement shall be deemed to be followed by “without
limitation”. The use of the words “or,” “either” or “any” shall not be exclusive. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of
intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions
of this Agreement. All references to laws, rules, regulations and forms in this Agreement shall be deemed to be references to such laws, rules, regulations and forms, as amended from time to time or, to the extent replaced, the comparable successor
thereto in effect at the time. All references to agencies, self-regulatory organizations or governmental entities in this Agreement shall be deemed to be references to the comparable successors thereto from time to time. 

(o) Entire Agreement. This Agreement and any certificates, documents, instruments and writings that are delivered pursuant hereto,
constitutes the entire agreement and understanding of the parties in respect of the subject matter hereof and supersedes all prior understandings, agreements or representations by or among the parties, written or oral, to the extent they relate in
any way to the subject matter hereof. 
 (p) Termination. The obligations of the Company and of any Holder, other than those
obligations contained in Section 8 and this Section 13, shall terminate with respect to the Company and such Holder as soon as such Holder no longer beneficially owns any Registrable Securities.

 Appendix A 

DEFINITION OF “BENEFICIAL OWNERSHIP” 
  

	1.	 A “Beneficial Owner” of a security includes any person who, directly or indirectly, through any
contract, arrangement, understanding, relationship or otherwise has or shares: 

 (a) Voting power which
includes the power to vote, or to direct the voting of, such security; and/or 
 (b) Investment power which includes the
power to dispose, or direct the disposition of, such security. 
 Please note that either voting power or investment power, or both, is
sufficient for you to be considered the beneficial owner of shares. 
  

	2.	 Any person who, directly or indirectly, creates or uses a trust, proxy, power of attorney, pooling arrangement
or any other contract, arrangement or device with the purpose or effect of divesting such person of beneficial ownership of a security or preventing the vesting of such beneficial ownership as part of a plan or scheme to evade the reporting
requirements of the federal securities acts shall be deemed to be the beneficial owner of such security. 

  

	3.	 Notwithstanding the provisions of paragraph (1), a person is deemed to be the “beneficial owner” of a
security if that person has the right to acquire beneficial ownership of such security within 60 days, including but not limited to any right to acquire: (a) through the exercise of any option, warrant or right; (b) through the conversion
of a security; (c) pursuant to the power to revoke a trust, discretionary account or similar arrangement; or (d) pursuant to the automatic termination of a trust, discretionary account or similar arrangement; provided,
however, any person who acquires a security or power specified in (a), (b) or (c) above, with the purpose or effect of changing or influencing the control of the issuer, or in connection with or as a participant in any transaction having
such purpose or effect, immediately upon such acquisition shall be deemed to be the beneficial owner of the securities which may be acquired through the exercise or conversion of such security or power. 

 Exhibit C 

FORM OF PLAN OF DISTRIBUTION 
 The Selling
Stockholders intend to distribute the Registrable Securities pursuant to the Shelf Registration Statement only as follows: such Registrable Securities may be sold from time to time directly by the Selling Stockholders or alternatively through
broker-dealers or agents. If the Registrable Securities are sold through broker-dealers or agents, the Selling Stockholders shall be responsible for discounts or commissions. Such Registrable Securities may be sold in one or more transactions at
fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale or at negotiated prices. Such sales may be effected in transactions (which may involve crosses or block transactions) (i) on any
national securities exchange or quotation service on which the Registrable Securities may be listed or quoted at the time of sale, (ii) in the over-the-counter
market, or (iii) in transactions otherwise than on such exchanges or services or in the over-the-counter market. In no event will such method(s) of distribution
take the form of an underwritten offering of the Registrable Securities.
