2. Registration. 
 (a) On or prior to its applicable Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering the resale of all Registrable Securities not already covered by an
existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. Each Registration Statement required to be filed under this Agreement shall be filed on Form S-3 (or if the Company is not then
eligible to utilize such form of registration, it shall utilize such other available form appropriate for such purpose) and contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such
Registration Statement, other than as to the characterization of any Holder as an underwriter, which shall not occur without such Holder’s written consent) the “Plan of Distribution” attached hereto as Annex B. The Company
shall cause each Registration Statement required to be filed under this Agreement to be declared effective under the Securities Act as soon as possible but, in any event, no later than its Effectiveness Date, and shall use its reasonable best
efforts to keep each such Registration Statement continuously effective during its entire Effectiveness Period. By 5:00 p.m. (New York City time) on the Business Day immediately following the Effective Date of each Registration Statement, the
Company shall file with the Commission in accordance with Rule 424 the final 

  
 3 

 
prospectus to be used in connection with sales pursuant to such Registration Statement (whether or not such filing is technically required under such Rule). If for any reason other than due
solely to SEC Restrictions, a Registration Statement is effective but not all outstanding Registrable Securities are registered for resale pursuant thereto, then the Company shall prepare and file by the applicable Filing Date an additional
Registration Statement to register the resale of all such unregistered Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415. 
 (b) Notwithstanding anything to the contrary contained in this Section 2, if the Company receives Commission Comments, and following discussions with and responses to the Commission in which the
Company uses its reasonable best efforts and time to cause as many Registrable Securities for as many Holders as possible to be included in the Registration Statement filed pursuant to Section 2(a) without characterizing any Holder as an
underwriter (and in such regard uses its reasonable best efforts to cause the Commission to permit the affected Holders or their respective counsel to participate in Commission conversations on such issue together with Company Counsel, and timely
conveys relevant information concerning such issue with the affected Holders or their respective counsel), the Company is unable to cause the inclusion of all Registrable Securities, then the Company may, following not less than three
(3) Trading Days prior written notice to the Holders (i) remove from the Registration Statement such Registrable Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the
registration and resale of the Registrable Securities, in each case as the Commission may require in order for the Commission to allow such Registration Statement to become effective; provided, that in no event may the Company name any Holder
as an underwriter without such Holder’s prior written consent (collectively, the “SEC Restrictions”). Unless the SEC Restrictions otherwise require, any cut-back imposed pursuant to this Section 2(b) shall be allocated
among the Registrable Securities of the Holders on a pro rata basis. No registration delay payments under Section 2(c) shall accrue on or as to any Cut Back Shares, and the required Effectiveness Date for such Registration Statement will be
tolled, until such time as the Company is able to effect the registration of the Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date”). From and after the Restriction Termination
Date, all provisions of this Section 2 (including, without limitation, the registration delay payment provisions, subject to tolling as provided above) shall again be applicable to the Cut Back Shares (which, for avoidance of doubt, retain
their character as “Registrable Securities”) so that the Company will be required to file with and cause to be declared effective by the Commission such additional Registration Statements in the time frames set forth herein as necessary to
ultimately cause to be covered by effective Registration Statements all Registrable Securities. 
 (c) If: (i) a
Registration Statement is not filed on or prior to its Filing Date covering the Registrable Securities required under this Agreement to be included therein (if the Company files a Registration Statement without affording the Holders the opportunity
to review and comment on the same as required by Section 3(a) hereof, the Company shall not be deemed to have satisfied this clause (i)), or (ii) a Registration Statement is not declared effective by the Commission on or prior to its
required Effectiveness Date or if by the Business Day immediately following the Effective Date, the Company shall not have filed a “final” prospectus for the Registration Statement with the Commission under Rule 424(b) in accordance with
the terms hereof (whether or not such a prospectus is technically required by such Rule), or (iii) after its 

  
 4 

 
Effective Date, without regard for the reason thereunder or efforts therefor, such Registration Statement ceases for any reason to be effective and available to the Holders as to all Registrable
Securities to which it is required to cover at any time prior to the expiration of its Effectiveness Period for more than an aggregate of 30 Trading Days (which need not be consecutive), or (iv) the Company fails, during the period from the six
month anniversary of the Closing Date to the one year anniversary of the Closing Date, to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company pursuant to
the Exchange Act, other than Form 8-K reports (any such failure or breach being referred to as an “Event,” and for purposes of clauses (i), (ii), or (iv) the date on which such Event occurs, or for purposes of clause
(iii) the date which such 30 Trading Day-period is exceeded, being referred to as “Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each
monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial registration delay payments and not
as a penalty, equal to the product of (x) the product of (A) 1.0% multiplied by (B) the quotient of (i) the number of such Holder’s Registrable Securities that are not then covered, but are required to be covered, by a
Registration Statement that is then effective and available for use by such Holder divided by (ii) the total number of such Holder’s Registrable Securities multiplied by (y) the aggregate Investment Amount paid by such Holder for the
Shares pursuant to the Purchase Agreement. The parties hereto agree that in no event will the Company be liable for any registration delay payments under this Agreement in excess of 1.0% of the aggregate Investment Amount of the Holders in any
30-day period and the maximum aggregate registration delay payments payable to a Holder under this Agreement shall be 10% of the aggregate Investment Amount paid by such Holder pursuant to the Purchase Agreement. The partial registration delay
payments pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a month prior to the cure of an Event (except in the case of the first Event Date), and shall cease to accrue (unless earlier cured) upon the expiration
of the Effectiveness Period. For the avoidance of doubt, in no event shall the Company be liable for registration delay payments with respect to Cut Back Shares. 
 (d) Each Holder agrees to furnish to the Company a completed Questionnaire in the form attached to this Agreement as Annex C (a “Selling Holder Questionnaire”). The Company shall
not be required to include the Registrable Securities of a Holder in a Registration Statement and shall not be required to pay any registration delay payments under Section 2(c) to any Holder who fails to furnish to the Company a fully
completed Selling Holder Questionnaire at least two Trading Days prior to the Filing Date (subject to the requirements set forth in Section 3(a)). 
 3. Registration Procedures. 
 In connection with the Company’s
registration obligations hereunder, the Company shall: 
 (a) Not less than four Trading Days prior to the filing of a
Registration Statement or any related Prospectus or any amendment or supplement thereto, the Company shall furnish to each Holder copies of the “Selling Stockholders” section of such document, the “Plan of Distribution” and any
risk factor contained in such document that addresses specifically this 

  
 5 

 
transaction or the Selling Stockholders, as proposed to be filed, which documents will be subject to the review of such Holder. The Company shall not file a Registration Statement, any Prospectus
or any amendments or supplements thereto in which the “Selling Stockholder” section thereof differs from the disclosure received from a Holder in its Selling Holder Questionnaire (as amended or supplemented). The Company shall not file a
Registration Statement, any Prospectus or any amendments or supplements thereto in which it (i) characterizes any Holder as an underwriter, (ii) excludes a particular Holder due to such Holder refusing to be named as an
underwriter, or (iii) reduces the number of Registrable Securities being registered on behalf of a Holder except pursuant to, in the case of subsections (ii) or (iii), the Commission Comments, without, in each case, such Holder’s
express written authorization. 
 (b)  (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its
Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or
supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to each
Registration Statement or any amendment thereto and, as promptly as reasonably possible provide the Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that would not result in
the disclosure to the Holders of material and non-public information concerning the Company; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statement(s)
and the disposition of all Registrable Securities covered by each Registration Statement. 
 (c) Notify the Holders as promptly
as reasonably possible (and, in the case of (i)(A) below, not less than three Trading Days prior to such filing and, in the case of (v) below, not less than three Trading Days prior to the financial statements in any Registration Statement
becoming ineligible for inclusion therein) and (if requested by any such Person) confirm such notice in writing no later than one Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a
Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration
Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders that pertain to the Holders as a Selling Stockholder or to the Plan of Distribution, but not information which the Company
believes would constitute material and non-public information); and (C) with respect to each Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a
Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or
exemption from qualification of any of the Registrable 

  
 6 

 
Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes the
financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in
any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. 

(d) Use its reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the
effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment. 

(e) Furnish to each Holder, upon request and without charge, at least one conformed copy of each Registration Statement and each
amendment thereto and all exhibits to the extent requested by such Person (including those previously furnished) promptly after the filing of such documents with the Commission unless a requested document is available on EDGAR. 

(f) Promptly deliver to each Holder, upon request and without charge, as many copies of each Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request unless a requested document is available on EDGAR. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 
 (g) Prior to any public offering of Registrable Securities, register or qualify such Registrable Securities for offer and sale under the securities or Blue Sky laws of all jurisdictions within the United
States as any Holder may request, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by the Registration Statement(s). 
 (h) Cooperate with the Holders to
facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement(s), which certificates shall be free, to the extent permitted by the Purchase
Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request. 
 (i) Upon the occurrence of any event contemplated by Section 3(c)(v), as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to the affected
Registration Statements or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other 

  
 7 

 
required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will 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, in light of the circumstances under which they were made, not misleading. 
 4. Registration Expenses. All fees and expenses incident to the performance of or compliance with this Agreement by the Company 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 registration and filing fees (including, without limitation, fees and expenses
(A) with respect to filings required to be made with any Trading Market on which the Common Stock is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky laws), (ii) printing expenses (including,
without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by the holders of a majority of the Registrable Securities included in the
Registration Statement), (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 this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection
with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and
expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. 
 5. Indemnification. 
 (a) Indemnification by the Company. The Company
shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, investment advisors, partners, members 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, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and
against any and all out of pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred,
arising out of or relating to 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
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 form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (1) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing 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 reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being 

  
 8 

 
understood that the Holder has approved Annex B hereto for this purpose) or (2) in the case of an occurrence of an event of the type specified in Section 3(c)(ii)-(v), 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 an Advice or an amended or supplemented Prospectus, but only
if and to the extent that following the receipt of the Advice or the amended or supplemented Prospectus the misstatement or omission giving rise to such Loss would have been corrected. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement. 
 (b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its 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 solely out of or based solely upon: (x) such Holder’s failure to comply with the prospectus delivery requirements of the Securities Act or (y) any 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 arising solely out of or based solely upon any omission of a material fact required to be stated therein or necessary to make the
statements therein not misleading to the extent, but only to the extent that, (1) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing 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 reviewed and expressly approved in writing by such Holder expressly for use in the
Registration Statement (it being understood that the Holder has approved Annex B hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of
the type specified in Section 3(c)(ii)-(v), 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 an Advice or an amended or supplemented Prospectus, but only if and to the extent that following the receipt of the Advice or the amended or supplemented Prospectus 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.

 (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 assume
the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all 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 it shall be finally determined by a court of competent jurisdiction (which
determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party. 

  
 9 

 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 a conflict of interest is likely to exist if the same counsel were to represent such
Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not
have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. 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. 
 All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not
entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party
is not entitled to indemnification hereunder). 
 (d) Contribution. If a claim for indemnification under
Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), 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 amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this
Section was available to such party in accordance with its terms. 

  
 10 

 The parties hereto agree that it would not be just and equitable if contribution pursuant to
this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of
this Section 5(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. 
 The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties. 

6. Miscellaneous. 
 (a) Remedies. In the event of a breach by the Company or by a Holder, of any of their respective obligations under this Agreement, each Holder or the Company, as the case may be, in addition to
being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would
not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall
waive the defense that a remedy at law would be adequate. 
 (b) No Piggyback on Registrations. Neither the Company nor
any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in a Registration Statement other than the Registrable Securities. 

(c) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities
Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement. 
 (d)
Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(c), such Holder will
forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemented Prospectus and/or amended Registration Statement or until it is advised in writing
(the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus or Registration Statement. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. 

  
 11 

 (e) Piggy-Back Registrations. If at any time during the Effectiveness Period there is
not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then the Company shall send to each Holder written notice of such determination and, if within fifteen calendar days
after receipt of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered, subject to customary
underwriter cutbacks applicable to all holders of registration rights and subject to the applicable terms of such registration rights. 
 (f) Amendments and Waivers. The provisions of this Agreement, including the provisions of this Section 6(f), may not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders of no less than a majority in interest of the then outstanding Registrable Securities, and any amendment to any provision of
this Agreement made in accordance with this Section shall be binding on all Investors and Holders, as applicable. 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 at least a majority of the Registrable Securities to which such waiver or consent relates;
provided, further that no amendment or waiver to any provision of this Agreement relating to naming any Holder or requiring the naming of any Holder as an underwriter may be effected in any manner without such Holder’s prior written
consent. Section 2(a) may not be amended or waived except by written consent of each Holder affected by such amendment or waiver. 
 (g) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of

 (i) Execution and Counterparts. This Agreement
may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile

(j) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, employees or agents) will be commenced in the New York Courts. Each party hereto hereby irrevocably submits to the
exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any
Proceeding, any claim that it is not personally subject to the jurisdiction of any New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of
process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this

RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. If either party shall commence a Proceeding to enforce any provisions of this Agreement, then the prevailing party in such Proceeding shall be reimbursed by the other party for
its attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding. 
 (k) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. 
 (l) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
 (m) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. 

(n) Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under this Agreement are
several and not joint with the obligations of each other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under this Agreement. Nothing contained herein or in any Transaction
Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way
acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any other Transaction Document. Each Investor acknowledges that no other Investor will be acting as agent of such Investor in
enforcing its rights under this Agreement. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Investor
to be joined as an additional party in any Proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Registration Rights Agreement for the purpose of closing a transaction with multiple
Investors and not because it was required or requested to do so by any Investor.

 Annex B 
 Plan of Distribution 
 The Selling Stockholders and any of their pledgees, donees,
transferees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or quoted or in private transactions. These
sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling shares: 
  

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

 

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

  

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

 

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

 

	 	•	 	 privately negotiated transactions; 

  

	 	•	 	 to cover short sales made after the date that this Registration Statement is declared effective by the Commission; 

 

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

  

	 	•	 	 a combination of any such methods of sale; and 

  

	 	•	 	 any other method permitted pursuant to applicable law. 

 The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus. 

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may
receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved. 
 The Selling Stockholders may from time to time
pledge or grant a security interest in some or all of the Shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of Common Stock from time to time under
this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest
as selling stockholders under this prospectus. 

 Upon the Company being notified in writing by a Selling Stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of Common Stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be
filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such Selling Stockholder and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which
such the shares of Common Stock were sold, (iv)the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction. In addition, upon the Company being notified in writing by a Selling Stockholder that a donee or pledgee intends to sell more than 500 shares
of Common Stock, a supplement to this prospectus will be filed if then required in accordance with applicable securities law. 

The Selling Stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or
other successors in interest will be the selling beneficial owners for purposes of this prospectus. 
 The Selling Stockholders
and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such
broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, that
can be attributed to the sale of Securities will be paid by the Selling Stockholder and/or the purchasers. Each Selling Stockholder has represented and warranted to the Company that it acquired the securities subject to this Registration Statement
in the ordinary course of such Selling Stockholder’s business and, at the time of its purchase of such securities such Selling Stockholder had no agreements or understandings, directly or indirectly, with any person to distribute any such
securities. 
 The Company has advised each Selling Stockholder that it is the view of the Commission that it may not use shares
registered on this Registration Statement to cover short sales of Common Stock made prior to the date on which this Registration Statement shall have been declared effective by the Commission. If a Selling Stockholder uses this prospectus for any
sale of the Common Stock, it will be subject to the prospectus delivery requirements of the Securities Act. The Selling Stockholders will be responsible to comply with the applicable provisions of the Securities Act and Exchange Act, and the rules
and regulations thereunder promulgated, including, without limitation, Regulation M, as applicable to such Selling Stockholders in connection with resales of their respective shares under this Registration Statement. 

The Company is required to pay all fees and expenses incident to the registration of the shares, but the Company will not receive any
proceeds from the sale of the Common Stock. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
