Statement for the maximum period permitted by SEC rules, and shall replace any Shelf Registration Statement at or before expiration, if applicable, with a successor effective Shelf Registration Statement to the extent any Registrable Securities
remain outstanding. 
 (b) Right to Request Shelf Take-Down. At any time after the Closing Date, either of the
Principal Holders (the “Initiating Holder”) may, by written notice to Parent, request at any time that a shelf registration statement (including the Shelf Registration Statement) covering the Registrable Securities is effective, an
offering of all or part of the

Registrable Securities held by the Principal Holders (a “Shelf Take-Down”). The Principal Holders shall be entitled to request two (2) Shelf Take-Downs; provided,

Dollars ($10,000,000). 
 (c) Shelf Take-Down Notice. Parent shall give written notice to the Principal Holder that
did not initiate the Shelf Take-Down at least five (5) Business Days prior to the commencement of the Shelf Take-Down and, subject to the applicable priority and cutback provisions set forth herein, shall include in such Shelf Take-Down all
Registrable Securities of such Principal Holder so long as Parent has received a written request from such Principal Holder no later than three (3) days prior to commencement of the Shelf Take-Down; provided, however, that such
Principal Holder shall be entitled to waive such written notice requirement or agree to a shorter period. 
 (d) Demand
Registration Statement If Shelf Registration Statement Unavailable. If Parent is ineligible to file with the SEC a shelf registration statement on Form S-3 (or successor form) in accordance with
Section 2(a), upon the written request of either Principal Holder (a “Demand Registration”), Parent shall use commercially reasonable efforts to file promptly a Registration Statement on Form
S-1 (or successor form) (a “Demand Registration Statement”) registering for resale such number of shares of Registrable Securities requested to be included in the Demand Registration Statement
and have the Demand Registration Statement declared effective under the Securities Act as promptly as practicable. Parent shall give written notice to the Principal Holder that did not initiate the Demand Registration Statement request at least
fifteen (15) days prior to the initial filing of a Demand Registration Statement and, subject to the applicable priority and cutback provisions set forth herein, shall include in such Demand Registration Statement all Registrable Securities of
such Principal Holder so long as Parent has received a written request from such Principal Holder no later than ten (10) days after delivery or deemed delivery of such notice. After any Demand Registration Statement has become effective, Parent
shall use commercially reasonable efforts to keep such Demand Registration Statement continuously effective until all of the Registrable Securities covered by such Demand Registration Statement have been sold in accordance with the plan of
distribution set forth therein or are no longer outstanding. 
 (e) Number of Demand Registrations. Each of the
Principal Holders shall be entitled to request a maximum of one (1) Demand Registrations. A registration shall not count as a Demand Registration until the related Demand Registration Statement has been declared effective by the SEC. 

(f) Selection of Underwriters; Right to Participate. Parent shall have the right to select the managing underwriters to
administer an offering pursuant to a Demand Registration Statement or Shelf Take-Down. A Principal Holder may participate in a registration or offering hereunder only if such Principal Holder (i) agrees to sell such Registrable Securities on
the basis provided in any underwriting agreement with the underwriters and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up agreements and
other documents reasonably requested under the terms of such underwriting arrangements customary for selling stockholders to enter into in secondary underwritten public 

  
 4 








 
offerings, provided that any underwriting agreement shall contain such representations and warranties by, and the other agreements on the part of, Parent to and for the benefit of the
Principal Holders as are customarily made by issuers to selling stockholders in secondary underwritten public offerings. 

(g) Priority of Securities Offered Pursuant to Demand Registrations and Shelf Take-Downs. If the managing underwriter
of a Demand Registration or Shelf Take-Down shall advise Parent that in its reasonable opinion the number of Registrable Securities requested to be included in such Demand Registration or Shelf Take-Down exceeds the number that can be sold in such
offering without having an adverse effect on such offering, including the price at which such Shares can be sold, then Parent shall include in such Demand Registration or Shelf Take-Down the maximum number of Registrable Securities that such
underwriter or agent, as applicable, advises can be so sold without having such adverse effect, allocated (i) first, to Registrable Securities requested by the Principal Holders to be included in such Demand Registration or Shelf Take-Down
allocated among such requesting Principal Holders on a pro rata basis or in such other manner as they may agree and (ii) second, to Shares requested to be included by Parent. 

(h)Postponement; Suspensions. 

(i) Parent may postpone the filing or the effectiveness of a Demand Registration Statement or commencement of a
Shelf Take-Down if, based on the good faith judgment of Parent’s Board of Directors, such postponement is necessary in order to avoid premature disclosure of material non-public information that the Board
of Directors, after consultation with outside counsel to Parent, has in good faith determined would (i) be required to be made in any Registration Statement or report filed with the SEC by Parent so that such Registration Statement or report
would not contain 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 if such information is not included, (ii) such disclosure would
not be required to be made at such time but for the filing of such Registration Statement and (iii) Parent has a bona fide business purpose for not disclosing publicly, and Parent delivers to the requesting Holders an officers’ certificate
executed by Parent’s principal executive officer and principal financial officer stating such; provided, however, that the Initiating Holder requesting such Demand Registration Statement or Shelf Take-Down shall be entitled, at
any time after receiving notice of such postponement and before such Demand Registration Statement becomes effective or before such Shelf Take-Down is commenced, to withdraw such request and, if such request is withdrawn, such Demand Registration or
Shelf Take-Down shall not count as a Demand Registration or, if applicable, a Shelf Take-Down involving Substantial Marketing Efforts. Parent shall provide prompt written notice to such Initiating Holder of (x) any postponement of the filing or
effectiveness of a Demand Registration Statement or commencement of a Shelf Take-Down, (y) Parent’s decision to file or seek effectiveness of such Demand Registration Statement or commence such Shelf Take-Down following such postponement
and (z) the effectiveness of such Demand Registration Statement or commencement of such Shelf Take-Down. Notwithstanding the provisions of this Section, Parent may not postpone the filing or effectiveness of a Demand Registration Statements or
the commencement of a Shelf Take-Down more than twice during any twelve-month period or for a period exceeding sixty (60) days in the aggregate in any twelve-month period. 

  
 5 








 (ii) If the continued use of an effective Demand Registration
Statement or Shelf Registration Statement at any time would (A) in the good faith judgment of Parent, be materially detrimental to Parent and its stockholders or (B) require public disclosure of material
non-public information that the Parent’s Board of Directors, after consultation with outside counsel to Parent, has in good faith determined (1) would be required to be made in any Demand
Registration Statement or Shelf Registration Statement filed with the SEC by Parent so that such Demand Registration Statement or Shelf Registration Statement, from and after its effective date, does not contain 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, (2) would not be required to be made at such time but for the continued use of such Demand Registration Statement or
Shelf Registration Statement and (3) Parent has a bona fide business purpose for not disclosing publicly, Parent may, upon giving prompt written notice (a “Suspension Notice”) of such action to the Holders, suspend use of the
Demand Registration Statement or Shelf Registration Statement, as applicable (a “Suspension”); provided, however, that Parent shall not be permitted to exercise a Suspension (x) more than twice during any 12-month period or (y) for a period exceeding sixty (60) days on any one occasion. No Holder shall effect any sales of Shares pursuant to a Demand Registration Statement or Shelf Registration Statement at
any time after it has received a Suspension Notice from Parent and prior to receipt of an End of Suspension Notice (as defined below). Each Holder may recommence effecting sales of Shares pursuant to the Demand Registration Statement or Shelf
Registration Statement following further written notice to such effect (an “End of Suspension Notice”) from Parent to the Holders. 

(iii) Each Holder agrees that, except as required by applicable law, it shall treat as confidential the receipt
of any Suspension Notice (provided that in no event shall such notice contain any material nonpublic information of Parent) hereunder and shall not disclose or use the information contained in such Suspension Notice without the prior written consent
of Parent until such time as the information contained therein is or becomes public, other than as a result of disclosure by breach of the terms of this Agreement.

 Section 4. Indemnification. 

(a) Indemnification by Parent. Parent agrees to indemnify, hold harmless and reimburse, to the fullest extent permitted
by law, each Holder, its partners, officers, directors, employees, advisors, representatives and agents, and each person, if any, who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any and all losses,
penalties, liabilities, claims, damages and expenses, joint or several (including, without limitation, reasonable attorneys’ fees and any expenses and reasonable costs of investigation), as incurred, to which the Holders or any such indemnitees
may become subject under the Securities Act or otherwise, insofar as such losses, penalties, liabilities, claims, damages and expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered and sold under the Securities Act, any preliminary prospectus, final prospectus,
free writing prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading or any violation of the Securities Act or state securities laws or rules thereunder by Parent relating to any action or inaction by Parent in
connection with such registration; provided, however, that Parent shall not be liable in any such case to the extent that any such loss, penalty, liability, claim, damage (or action or proceeding in respect thereof) or expense arises
out of or is based upon an untrue statement or alleged statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and
in conformity with written information about a Holder which is furnished to Parent by such Holder specifically for use in such registration statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on
behalf of such Holder or any indemnified party and shall survive the transfer of such securities by such Holder. 
 (b)
Indemnification by the Holders. Each Holder agrees to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 4(a)) Parent, each member of the Board, each officer, employee and agent of Parent and
each other person, if any, who controls any of the foregoing within the meaning of the Securities Act or the Exchange Act, with respect to any untrue statement or alleged untrue statement of a material fact in or omission or alleged omission to
state a material fact from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information about such Holder furnished to Parent by such Holder specifically for inclusion in such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or supplement and has not been corrected in a subsequent registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto prior to or concurrently with the sale of the Registrable Securities to the person asserting the claim; provided, however, that Holder shall not be liable for any amounts in excess of the net proceeds
received by such Holder from sales of Registrable Securities pursuant to the registration statement to which the claims relate, and provided, further, that the obligations of the Holders shall be several and not joint and several. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of Parent or any indemnified party and shall survive the transfer of such securities by Parent. 

  
 11 








 (c) Notices of Claims, etc. Promptly after receipt by an indemnified party
of notice of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 4, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give
written notice to such indemnifying party of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations
under the preceding paragraphs of this Section 4, except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such
indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, such indemnified party shall permit such indemnifying party to assume the defense of such
claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such
claim, but the fees and expenses of such counsel shall be at the expense of such person unless (A) the indemnifying party has agreed to pay such fees or expenses or (B) the indemnifying party shall have failed to assume the defense of such
claim and employ counsel reasonably satisfactory to such person within a reasonable time after receipt of notice of such claim from the person entitled to indemnification hereunder. If such defense is not assumed by the indemnifying party as
permitted hereunder, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). If such defense is
assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (i) such settlement or compromise contains a full and unconditional release of the
indemnified party of all liability in respect to such claim or litigation or (ii) the indemnified party otherwise consents in writing. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party, a conflict of
interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of such additional counsel
or counsels. 
 The indemnification provided for under this Agreement shall remain in full force and effect regardless of
any investigation made by or on behalf of the indemnified party and shall survive the transfer of securities. 
 (d)
Contribution. If the foregoing indemnity is held by a governmental authority of competent jurisdiction to be unavailable to Parent or any Holder, or is insufficient to hold harmless an indemnified party, then the indemnifying party shall
contribute to the amount paid or payable by the indemnified party as a result of the loss, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, and the
relative benefits received by the indemnifying party and the 

  
 12 








 
indemnified party, as well as any other relevant equitable considerations. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation. In connection with any registration statement filed with the SEC by Parent, the relative fault of the indemnifying party on
the one hand and of the indemnified person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates
to information supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the
provisions of this Section, no Holder shall be required to contribute an amount greater than the net proceeds received by such Holder from sales of Registrable Securities pursuant to the registration statement to which the claims relate (after
taking into account the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Securities). 

(e) No Exclusivity. The remedies provided for in this Section 4 are not exclusive and shall not limit any rights
or remedies which may be available to any indemnified party at law or in equity or pursuant to any other agreement. 

Section 5. Covenants Relating to Rule 144. Parent shall use commercially reasonable efforts to file any reports
required to be filed by it under the Securities Act and the Exchange Act and to take such further action as any Holder may reasonably request to enable Holders to sell Registrable Securities without registration under the Securities Act from time to
time within the limitation of the exemptions provided by Rule 144. Parent shall, in connection with any request by Holder in connection with a sale, transfer or other disposition by any Holder of any Registrable Securities pursuant to Rule 144
either currently or prospectively with unspecified timing, promptly cause (and in no event longer than five Business Days after request) the removal of any restrictive legend or similar restriction on the Registrable Securities, and, in the case of
book-entry shares, make or cause to be made appropriate notifications on the books of Parent’s transfer agent for such number of shares and registered in such names as the Holders may reasonably request and to provide a customary opinion of
counsel and instruction letter required by Parent’s transfer agent. 
 Section 6. Miscellaneous. 

(a) [reserved] 

(b) Termination; Survival. The rights of each Holder under this Agreement shall terminate upon the date that all of the
Registrable Securities held by such Holder cease to be Registrable Securities. Notwithstanding the foregoing, the obligations of the parties under Sections 3(a)(viii), 4, 5 and this Section 6 shall survive the termination of this Agreement.


  
 13 








 (c) Governing Law. This Agreement and any claim, controversy or dispute
arising under or related to this Agreement, whether in law or in equity, whether in contract or in tort, by statute or otherwise, shall be governed and construed in accordance with the Laws of the State of Delaware without giving effect to the

MOTION OR OTHER REQUEST FOR LEAVE FROM ANY SUCH COURT, AND AGREES NOT TO PLEAD OR CLAIM ANY OBJECTION TO THE LAYING OF VENUE IN ANY SUCH COURT OR THAT ANY JUDICIAL PROCEEDING IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM,
(C) AGREES THAT IT WILL NOT BRING ANY ACTION (WHETHER IN LAW OR IN EQUITY, WHETHER IN CONTRACT OR IN TORT, BY STATUTE OR OTHERWISE) RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT IN ANY COURT OTHER THAN THE
COURT OF CHANCERY OF THE STATE OF DELAWARE AND ANY FEDERAL COURT LOCATED IN THE STATE OF DELAWARE, OR, IF NEITHER OF SUCH COURTS HAS SUBJECT MATTER JURISDICTION, ANY STATE COURT OF THE STATE OF DELAWARE HAVING SUBJECT MATTER JURISDICTION, AND
(D) CONSENTS TO SERVICE OF PROCESS BEING MADE THROUGH THE NOTICE PROCEDURES SET FORTH IN SECTION 6(k). EACH OF THE PARTIES HERETO HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

express or implied, oral or written. 
 (f) Amendments and Waivers. The provisions of this Agreement may be amended
or waived at any time only by the written agreement of Parent and the Holders of a majority of the Registrable Securities then outstanding. Any waiver, permit, consent or approval of any kind or character on the part of any such Holders of any
provision or condition of this Agreement must be made in writing and shall be effective only to the extent specifically set forth in writing. Any amendment or waiver affected in accordance with this paragraph shall be binding upon Parent and each
Holder of Registrable Securities. Notwithstanding the foregoing, no amendments may be made to this Agreement that adversely affect any Holder in a manner different than any other Holder without such Holder’s prior written consent. 

  
 14 








 (g) Assignment. Except as set forth herein, the rights and obligations of
a Holder under this Agreement shall not be assignable by such Holder without prior, express written consent of Parent. The rights and obligations of the Parent under this Agreement shall not be assignable by Parent without the consent of Holders of
a majority of Registrable Securities then outstanding. Notwithstanding the foregoing, the rights and obligations of any Principal Holder may be assigned to any Affiliate of such Principal Holder without the prior, express written consent of Parent.

or provision of this Agreement shall be found invalid, illegal or unenforceable in any respect by any court of law of competent jurisdiction, the remaining provisions shall be severable, valid and enforceable in accordance with their terms, and any
such invalidity, illegality or unenforceability in any jurisdiction shall not invalidate or render illegal or unenforceable such provision in any other jurisdiction.
