ARTICLE 2 

REGISTRATION RIGHTS 

Parent covenants and agrees as follows: 

Section 2.01. Registration. 

(a) Shelf Registration. 

(i) Following the date of this Agreement, Parent shall prepare, and, on or prior to the applicable Required Shelf Filing
Deadline, file with the SEC a Shelf Registration Statement (on Form S-3 if then eligible) under the Securities Act to permit the resale of the Registrable Securities from time to time as permitted by SEC Rule
415 (or any similar provision adopted by the SEC then in effect). If at the time of such filing, Parent is a WKSI, the Shelf Registration Statement shall be an automatic shelf registration statement on Form
S-3 that becomes effective upon filing with the SEC in accordance with SEC Rule 462(e) (an “ASR Filing”). If the Shelf Registration Statement does not qualify as an ASR Filing, Parent shall
use its commercially reasonable efforts to cause such Registration Statement to become or be declared effective as soon as practicable after the filing thereof and, in any event, within thirty (30) days after the filing thereof in the case of a
Shelf Registration Statement on Form S-3 that is not an ASR Filing or, if Form S-3 is not then available, within forty-five (45) days after the filing thereof in
the case of a Shelf Registration Statement on Form S-1 (or, in the case of either a Form S-3 that is not an ASR Filing or Form
S-1, within ninety (90) days after the filing thereof if the SEC notifies the Company that it will “review” the Shelf Registration Statement; provided that, Parent will promptly respond
to any and all comments received from the SEC, with a view towards causing such Shelf Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request promptly
following the resolution or clearance of all SEC comments). Following the effective date of the Shelf Registration Statement that is not an ASR Filing, Parent shall notify the Holders of the effectiveness of such Shelf Registration Statement. 

(ii) The Shelf Registration Statement shall be on Form S-3 or, if Form S-3 is not then available to Parent, on Form S-1 or such other form of registration statement as is then available to effect a registration for resale of such Registrable
Securities and shall contain a prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to SEC Rule 415 (or any successor or similar rule adopted by the SEC then in effect) at any time beginning on the effective
date for such Registration Statement. The Shelf Registration Statement shall provide for the distribution or resale pursuant to any method or combination of methods legally available to the Holders. 

  
 4 

 (iii) Parent shall use its commercially reasonable efforts to cause the
Shelf Registration Statement to remain effective, and to be supplemented and amended as promptly as reasonably practicable to the extent necessary to ensure that the Shelf Registration Statement is available or, if not available, that another
Registration Statement is available (which such Registration Statement shall also be referred to herein as the Shelf Registration Statement), for the resale of all the Registrable Securities until all of the Registrable Securities have ceased to be
Registrable Securities or the earlier termination of this Agreement (as to all Holders). 
 (iv) When effective, the Shelf
Registration Statement (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will 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 (in the case of any prospectus contained in the Shelf Registration Statement, such prospectus will not
include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which such statements are made, not misleading). 

(b) Shelf Takedowns. At any time that a Shelf Registration Statement is effective, if a Holder of Registrable Securities having an
aggregate value of at least five percent (5%) of the then outstanding Registrable Securities (the “Shelf Takedown Demand Threshold”) covered by such Shelf Registration Statement delivers a written notice to Parent (a “Shelf
Takedown Notice”) stating that such Holder intends to effect an offering of all or part (subject to the Shelf Takedown Demand Threshold) of its Registrable Securities included in such Shelf Registration Statement (a “Shelf
Takedown”) and Parent is eligible to use such Shelf Registration Statement for such Shelf Takedown, then Parent shall take all actions reasonably required, including amending or supplementing such Shelf Registration Statement or prospectus
(a “Shelf Supplement”), to enable such Registrable Securities to be offered and sold as contemplated by such Shelf Takedown Notice. Each Shelf Takedown Notice shall specify the number of Registrable Securities to be offered and sold
under the Shelf Takedown. Except in connection with a Shelf Takedown Block Trade (as defined below), upon receipt of a Shelf Takedown Notice, Parent shall promptly (but in no event later than two (2) Business Days after receipt of a Shelf
Takedown Notice) deliver notice of such Shelf Takedown Notice to each Holder holding at least five percent (5%) of the then outstanding Registrable Securities (and with such Registrable Securities registered on such Shelf Registration Statement) who
shall then have five (5) Business Days from the date such Shelf Takedown Notice is given to Parent to notify Parent in writing of their desire to be included in such Shelf Takedown. Parent shall prepare and file with the SEC a Shelf Supplement
as soon as reasonably practicable after the date on which it received the Shelf Takedown Notice and, if such Shelf Supplement is an amendment to such Shelf Registration Statement, shall use its commercially reasonable efforts to cause such Shelf
Supplement to be declared effective by the SEC as soon as practicable thereafter. At any time prior to the effective date of such Shelf Supplement or the “pricing” of any offering relating to a Shelf Takedown (including in connection with
an Underwritten Demand Registration pursuant to Section 2.03), the Holder who initiated such Shelf Takedown may revoke or withdraw such Shelf Takedown Notice on behalf of all Holders participating in such Shelf Takedown
without liability to such Holders, in each case by providing written notice to Parent. With respect to any Holder and its Affiliates, the first (1st) Shelf Takedown that has been so revoked or
withdrawn by the initiating Holder shall not count as one of the permitted Underwritten Demand Registrations pursuant to Section 2.03; provided that, for avoidance of doubt, any subsequent such Shelf Takedowns that
have been so revoked or withdrawn shall count as one of the permitted Underwritten Demand Registrations pursuant to Section 2.03. 

(c) Shelf Takedown Block Trade. Notwithstanding anything to the contrary in Section 2.01(b), if an
institutional Holder wishes, pursuant to a Shelf Takedown, to engage in an underwritten offering that does not involve a “roadshow” and which is commonly referred to as a “bought deal” or “block trade” (a “Shelf
Takedown Block Trade”), then notwithstanding the foregoing time periods, the Holder shall notify Parent and each of the other institutional Holders of the Shelf Takedown Block Trade by 1:00 p.m. Eastern Time on the Business Day prior to the
date such offering is proposed by such Holder to commence and such other Holders must elect whether or not to participate by 1:00 p.m. Eastern Time the day such offering 

  
 5 

 
is to commence, and Parent shall as promptly as reasonably practicable use its commercially reasonable efforts (including cooperating with such Holder with respect to the provision of necessary
information) to facilitate such Shelf Takedown Block Trade (which may close as early as two (2) Business Days after the date it commences), provided that the Holder requesting such Shelf Takedown Block Trade shall use reasonable best
efforts to work with Parent and the underwriters prior to making such request in order to facilitate preparation of the Registration Statement, prospectus and other offering documentation related to such Shelf Takedown Block Trade. 

Section 2.02. Piggyback Registration. If Parent proposes to register (including, for this purpose, a registration effected by
Parent for stockholders other than the Holders) any of its securities under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), Parent shall, as soon as reasonably
practicable (and in any event at least five (5) Business Days prior to the filing thereof), give each Holder holding at least five percent (5%) of the then outstanding Registrable Securities (the “Piggyback Threshold”) notice
of such registration. Upon the written request of each Holder given within two (2) Business Days after such notice is given by Parent, Parent shall, subject to the provisions of Section 2.03, cause to be registered all
of the Registrable Securities that each such Holder has requested to be included in such registration (subject to the Piggyback Threshold). Parent shall have the right to terminate or withdraw any registration initiated by it under this
Section 2.02 before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration, and each Holder of Registrable Securities shall be permitted to
withdraw all or part of such Holder’s Registrable Securities from any registration initiated by Parent under this Section 2.02 by giving written notice to Parent of such request to withdraw at any time prior to the
effective date of such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by Parent in accordance with Section 3.03. 

Section 2.03. Underwriting Requirements. 

(a) If, pursuant to a Shelf Takedown Notice, a Major Holder intends to distribute the Registrable Securities covered by the Shelf Takedown
Notice by means of an underwritten offering (including, for avoidance of doubt, a Shelf Takedown Block Trade) (each, an “Underwritten Demand Registration”), such Major Holder shall so advise Parent as a part of their request made
pursuant to the Shelf Takedown Notice, and Parent shall include such information in the notice it provides to the other Holders pursuant to Section 2.01(b); provided that (i) (A) Adage Capital Partners, L.P. may
effect no more than one (1) Underwritten Demand Registration in any 12-month period and (B) the Bain Entities may each effect no more than two (2) Underwritten Demand Registrations in any
12-month period and (ii) no Major Holder shall have the right to effect an Underwritten Demand Registration within ninety (90) days of the closing of an Underwritten Demand Registration. The underwriter will be selected by Parent and shall
be reasonably acceptable to a majority in interest of the Holders and Other RRA Holders participating in such Underwritten Demand Registration; provided, however, that in the case of a Shelf Takedown Block Trade, Holders and Other RRA
Holders of a majority in interest participating in such Underwritten Demand Registration can select the underwriter, provided the selected underwriter is reasonably acceptable to Parent. In such event, the right of any Holder to include such
Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwritten offering and the inclusion of such Holder’s Registrable Securities in the underwritten offering to the
extent provided herein. All Holders proposing to distribute their securities through such underwritten offering shall (together with Parent as provided in Section 3.01(e)) enter into an underwriting agreement in customary
form with the underwriter(s) selected for such underwritten offering. 
 (b) Notwithstanding any other provision of this
Section 2.03, if the underwriter advises the Holders in writing that marketing factors require a limitation on the number of shares to be offered in an underwritten offering, then Parent shall so advise all Holders of
Registrable Securities that otherwise would be included in such underwritten offering pursuant hereto, and the number of Registrable Securities that may be included in the underwritten offering shall be allocated among such Holders of Registrable
Securities and any Other RRA Holders in proportion (as nearly as practicable) to the number of Registrable Securities (or, in the case of any Other RRA Holders, registrable shares of Common Stock) owned by each selling Holder and Other RRA Holder,
as applicable, or in such other proportion as shall mutually be agreed to by all such selling Holders and Other RRA Holders. 

  
 6 

 (c) In connection with any underwritten offering of shares of Common Stock pursuant to
Section 2.02 (each, a “Piggyback Underwritten Registration”), Parent shall not be required to include any of the Holders’ Registrable Securities in such underwritten offering unless the Holders
accept the terms of the underwriting as agreed upon between Parent and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by Parent. If the total
number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the number of securities to be sold (other than by Parent) that the underwriters in their reasonable discretion determine is
compatible with the success of the offering, then Parent shall be required to include in the offering only that number of such securities, including Registrable Securities and securities held by Other RRA Holders, which the underwriters and Parent
in their sole discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the securities that
are included in such offering shall be allocated among the selling Holders and any selling Other RRA Holders in proportion (as nearly as practicable) to the number of Registrable Securities (or, in the case of Other RRA Holders, registrable shares
of Common Stock) owned by each selling Holder and selling Other RRA Holder, as applicable, or in such other proportions as shall mutually be agreed to by all such Holders and Other RRA Holders participating in the underwritten offering. For purposes
of the provisions in Section 2.03(a) and in this Section 2.03(c) concerning apportionment, for any selling Holder or selling Other RRA Holder that is a partnership, limited liability company, or
corporation, the partners, members, retired partners, retired members, stockholders, and Affiliates of such Holder or Other RRA Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members
and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder” or “selling Other RRA Holder,” and any pro rata reduction with respect to such “selling
Holder” and/or “selling Other RRA Holder” shall be based upon the aggregate number of Registrable Securities owned by all Persons included in such “selling Holder” and/or “selling Other RRA Holder,” as defined in
this sentence. 
 Section 2.04. Suspension Rights and Delay of Registration. 

(a) Suspension Rights. Notwithstanding any other provision of this Agreement, if Parent’s board of directors determines that
compliance with its obligations under this Article 2 would be materially detrimental to Parent and its stockholders because such registration would: (A) materially interfere with a significant acquisition, corporate reorganization,
financing or other similar transaction involving Parent; (B) require premature disclosure of material non-public information that Parent has a bona fide business purpose for preserving as confidential; or
(C) render Parent unable to comply with requirements under the Securities Act or Exchange Act (a “Suspension Event”); then Parent shall have the right to suspend, defer or delay compliance with its obligations under this
Article 2, other than its obligations to file a Shelf Registration Statement on or prior to the Required Shelf Filing Deadline in accordance with Section 2.01(a), for a period of not more than ninety (90) days (the
“Suspension Period”), provided that such right pursuant to this Section 2.04 may not be utilized more than twice in any 12-month period; provided,
however, that Parent shall be required to give written notice to discontinue sales of Registrable Securities pursuant to such Registration Statement (provided that each Holder may settle any then-contracted sales of Registrable
Securities, which such notice shall in no event contain any material non-public information regarding Parent) to each Holder whose Registrable Securities are included any such Registration Statement prepared
pursuant to this Article 2. Such suspension will continue only for so long as the Suspension Event or its effect is continuing. Each Holder agrees not to effect any sales of its Registrable Securities pursuant to such Registration Statement
throughout the Suspension Period following receipt of a suspension notice from Parent until such Holder has received a written notice from Parent to such effect that a Holder may recommence effecting sales of the Registrable Securities pursuant to
such Registration Statement (or such filings) (an “End of Suspension Notice”) which such End of Suspension Notice will be given by Parent to the Holders promptly following the conclusion of any Suspension Event (and in any event
during the permitted Suspension Period). 
 (b) Delay of Registration. No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of Article 2 or Article 3 herein.

Underwritten Demand Registration or the Financial Counterparty(ies) in a Shelf Takedown Block Trade; 
 (p) Parent shall pay the SEC filing
fee covering all of the Registrable Securities to be registered pursuant to the Shelf Registration Statement at the time of filing such Registration Statement pursuant to Section 2.01(a). To the extent Parent is a WKSI at
the time any other Registration Statement covering any Registrable Securities is filed, and such Registration Statement is an ASR Filing, if Parent does not pay the filing fee covering the Registrable Securities at the time the ASR Filing is filed,
Parent agrees to pay such fee at such time or times as the Registrable Securities are to be sold. To the extent required in order to maintain an effective ASR Filing covering the Registrable Securities, Parent shall file a new ASR Filing covering
the Registrable Securities. Parent shall use its commercially reasonable efforts to remain a WKSI (and not become an ineligible issuer (as defined in SEC Rule 405)) during the period during which such ASR Filing is required to remain effective. If
at any time when Parent is required to re-evaluate its WKSI status Parent determines that it is not a WKSI and the ASR Filing is no longer available to be used to sell Registrable Securities, Parent shall use
its commercially reasonable efforts to file a new Shelf Registration Statement and keep such Shelf Registration Statement effective during the period during which such registration statement is required to be kept effective; 

(q) if Parent files any ASR Filing for the benefit of the holders of any of its securities other than all of the Holders, Parent agrees that,
if it is eligible to rely on SEC Rule 430B, it shall include such disclosures as may be required by SEC Rule 430B in order to ensure that the Holders may be added to such ASR Filing at a later time through the filing of a prospectus supplement
rather than a post-effective amendment; 
 (r) take no direct or indirect action prohibited by Regulation M under the Exchange Act; and 

(s) cooperate with each Holder covered by the registration statement and each underwriter or agent participating in the disposition of such
Registrable Securities and their respective counsel in connection with the preparation and filing of applications, notices, registrations and responses to requests for additional information with FINRA, the New York Stock Exchange, Nasdaq or any
other national securities exchange on which the shares of Parent’s capital stock are or are to be listed, and to the extent required by the rules and regulations of FINRA, retain a Qualified Independent Underwriter (as such term is defined
under Rule 5121 of the FINRA Manual) acceptable to the managing underwriter. 
 Section 3.02. Furnish Information. It shall be a
condition precedent to the obligations of Parent to take any action pursuant to Article 2 or Article 3 hereof with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to Parent such information
regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities. 

 

  
 9 

 Section 3.03. Expenses of Registration. All expenses (other than Selling
Expenses) incurred in connection with registrations, filings, or qualifications pursuant to Article 2 or Article 3 hereof, including, but not limited to, all registration, filing, and qualification fees; printers’ and accounting
fees; fees and disbursements of counsel for Parent; and the reasonable and documented fees and disbursements of one (1) counsel for the selling Holders (“Selling Holder Counsel”), not to exceed one hundred thousand
dollars ($100,000) in the aggregate per Underwritten Demand Registration or Piggyback Underwritten Registration, shall be borne and paid by Parent. All Selling Expenses relating to Registrable Securities registered pursuant to this Agreement shall
be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf. 

Section 3.04. In Kind Distributions. If any Major Holder seeks to effectuate an in-kind
distribution of all or part of their Registrable Securities to their respective direct or indirect equityholders, Parent will, subject to any applicable lock-ups, reasonably cooperate with and assist such
Major Holder, such equityholders and the Parent’s transfer agent to facilitate such in-kind distribution in the manner reasonably requested by such Major Holder (including the delivery of instruction
letters by Parent or its counsel to Parent’s transfer agent, the delivery of customary legal opinions by counsel to Parent and the delivery of Parent capital stock without restrictive legends, to the extent no longer applicable). 

ARTICLE 4 

INDEMNIFICATION 

Section 4.01. Indemnification by Parent. If any Registrable Securities are included in a Registration Statement under this
Agreement, to the extent permitted by law, rule or regulation (collectively, “Law”), Parent will indemnify and hold harmless each selling Holder of such Registrable Securities, and the partners, members, officers, directors, and
stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each Person, if any, who controls such Holder or underwriter within the meaning of the
Securities Act or the Exchange Act, against any Damages, and Parent will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with
investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 4.01 shall not apply
to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of Parent, which consent shall not be unreasonably withheld, nor shall Parent be liable for any Damages to the extent that they arise
out of or are based upon an untrue statement or omission made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling Person, or other aforementioned Person expressly for use
in connection with such registration. 
 Section 4.02. Indemnification by Holders. If any Registrable Securities are included in
a Registration Statement under this Agreement, to the extent permitted by Law, each selling Holder of such Registrable Securities, individually, and not on a joint and several basis, will indemnify and hold harmless Parent, and each of its
directors, each of its officers who has signed the registration statement, each Person (if any), who controls Parent within the meaning of the Securities Act, legal counsel and accountants for Parent, any underwriter (as defined in the Securities
Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other Holder, against any Damages, in each case only to the extent that such Damages result from written information
furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to Parent and each other aforementioned Person any legal or other expenses reasonably incurred thereby in
connection with investigating or defending any claim or proceeding from which such Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this
Section 4.02 shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided
further that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under this Section 4.02 and Section 4.04 exceed the proceeds from the offering
received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of gross negligence, fraud or willful misconduct by such Holder. 
  

  
 10 

 Section 4.03. Indemnification Procedures. Promptly after receipt by an
indemnified party under this Article 4 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Article 4, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying
party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties that may be represented without conflict by one (1) counsel) shall have the right to retain one (1) separate counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the indemnifying party would, in the reasonable opinion of counsel, be inappropriate due to actual or potential differing interests between such indemnified party and any other
party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party
under this Article 4, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may
have to any indemnified party otherwise than under this Article 4. 
 Section 4.04. Contribution. To provide for just and
equitable contribution to joint liability under the Securities Act in any case in which either (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Article 4 but it is
judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case,
notwithstanding the fact that this Article 4 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under
this
 Article 4, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is
appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to
reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material
fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct
or prevent such statement or omission; provided, however, that, in any such case, (x) no Holder will be required to contribute any amount in excess of the proceeds from the offering received by such Holder (net of any Selling
Expenses paid by such Holder) from all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this
Section 4.04, when combined with the amounts paid or payable by such Holder pursuant to Section 4.02, exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid
by such Holder), except in the case of willful misconduct or fraud by such Holder. 
 (a) Conflict. Notwithstanding the foregoing, to
the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control. 
 Section 4.05. Survival. Unless otherwise superseded by an underwriting agreement
entered into in connection with the underwritten public offering, the obligations of Parent and Holders under this Article 4 shall survive the completion of any offering of Registrable Securities in a registration under this Agreement, and
otherwise shall survive the termination of this Agreement.

 ARTICLE 5 

OTHER AGREEMENTS 

Section 5.01. Reports Under the Exchange Act. With a view to making available to the Holders the benefits of SEC Rule 144 and any
other rule or regulation of the SEC that may at any time permit a Holder to sell securities of Parent to the public without registration, Parent shall use commercially reasonable efforts to: 

(a) make and keep available adequate current public information, as those terms are understood and defined in SEC Rule 144; 

(b) file with the SEC in a timely manner all reports and other documents required of Parent under the Securities Act and the Exchange Act;

 (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a copy of the most
recent annual or quarterly report of Parent and such other reports and documents so filed by Parent and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the
selling of any such securities without registration or pursuant to Form S-3; provided, however, that the availability of such documentation on EDGAR shall satisfy such delivery requirement
hereunder; and 
 (d) take any and all action reasonably requested by such Holder in order to permit or facilitate such sale or transfer
pursuant to SEC Rule 144, including, without limitation, at the sole expense of Parent, by (i) issuing such directions to any transfer agent, registrar or depositary, as applicable, (ii) delivering such opinions to the transfer agent,
registrar or depositary as are customary for the transaction of this type and are reasonably requested by the same, and (iii) taking or causing to be taken such other actions as are reasonably necessary (in each case on a timely basis) in order
to cause any legends, notations or similar designations restricting transferability of the Registrable Securities held by such Holder to be removed and to rescind any transfer restrictions with respect to such Registrable Securities;
provided, however, that such Holder shall deliver to Parent, in form and substance reasonably satisfactory to Parent, representation letters regarding such Holder’s compliance with SEC Rule 144 as may be applicable. 

Section 5.02. Termination of Pre-existing Registration Rights. Each Holder expressly
acknowledges and agrees that, as of the effective time of the First Merger, this Agreement shall replace any pre-existing rights of the Holder with respect to the registration of its securities by Parent, the
Company or any of their respective subsidiaries, and that any pre-existing rights of such Holder with respect to the registration of its securities by Parent, the Company or any of their respective
subsidiaries, other than as set forth in this Agreement, are hereby irrevocably waived and terminated as of the effective time of the First Merger. 

Section 5.03. Limitations on Subsequent Registration Rights. As of the consummation of the First Merger, Parent shall not be a
party to any agreement, arrangement or understanding with respect to the registration of its securities, other than this Agreement, the agreements filed as exhibits to Parent’s Annual Report on Form 10-K
for the year ended December 31, 2021 (filed with the SEC on February 25, 2022) and the agreement filed as exhibit 4.12 to the Registration Statement on Form S-3 filed with the SEC on January 14,
2021. From and after the consummation of the First Merger, Parent shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective
holder of any securities of Parent that would provide to such holder the right to include securities in any underwritten offering on other than a pari passu or subordinate basis as compared to the Holders hereunder. To
the extent that Parent, on or after the date hereof and notwithstanding the prohibition in the preceding sentence, enters into any agreement with any holder or prospective holder of any securities of Parent that would provide to such holder the
right to include securities in any underwritten offering on other than a pari passu or subordinate basis as compared to the Holders hereunder, the Holders hereunder shall be deemed to have been granted simultaneously, and Parent
shall promptly prepare and execute such documents to reflect such grant, the right to include securities in any such underwritten offering on a pari passu basis with such holder or prospective holder. 

Section 5.04. No Inconsistent Agreements; Most Favored Nation. Parent will not hereafter enter, into any agreement with respect to
its Common Stock or securities convertible into or exercisable for Common Stock which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement. 

  
 12 

 Section 5.05. Lock-up Agreement. 

(a) Each of the Major Holders agrees that he, she or it will not, during the Lock-up Period,
(i) lend; offer; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, in each case whether effected
directly or indirectly, any Lock-up Shares Beneficially Owned by such Major Holder, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of such securities, whether any such transaction described in clause (i) or clause (ii) above is to be settled by delivery of Lock-up Shares or
other securities, in cash, or otherwise or (iii) publicly announce the intention to effect any of the transactions covered in clause (i) and clause (ii) above; provided that a Major Holder may enter
into a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Lock-up Shares so long as such plan does not provide for the transfer of Lock-up Shares during the Lock-up Period; provided further, that nothing herein shall prohibit any Major Holder from (A) pledging any Common Stock in connection
with such Person’s entry into a credit facility or any other bona fide borrowing or similar lending arrangement, which shall include margin loans (provided, that for the avoidance of doubt, any pledgee who receives Common Stock following the
exercise of remedies shall not be subject to the restrictions set forth in this Section 5.05(a)), (B) transferring any Lock-up Shares as a distribution or transfer to general
partners, limited partners, members or stockholders of any Major Holder, or to any corporation, partnership, limited liability company, investment fund or other entity which controls or manages or is controlled or managed by any such Major Holder,
or to any Affiliate under common control or management with any such Major Holder, (C) transferring any Common Stock in connection with the completion of a liquidation, merger, stock exchange or other similar transaction that results in all of
Parent’s securityholders having the right to exchange their shares of Common Stock for cash, securities or other property, (D) (x) transfers of Common Stock pursuant to a bona fide third-party tender offer for shares of the Parent’s
capital stock made to all holders of Parent’s securities or pursuant to a merger, consolidation or other similar transaction approved by the Board of Directors of Parent the result of which is that any person (as defined in
Section 13(d)(3) of the Exchange Act), or group of persons, other than Parent, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange
Act) of more than 50% of the total voting power of the voting stock of Parent and (y) entry into any lockup, voting or similar agreement pursuant to which the Major Holder may agree to transfer, sell, tender or otherwise dispose of shares of
Common Stock or such other securities in connection with a transaction described in the immediately foregoing clause (x) above (provided that, in the event that such change of control transaction is not completed, any Common Stock shall
remain subject to the restrictions contained in this Section 5.05(a)), or (E) by operation of law or pursuant to a final order of a court or regulatory agency; provided further, that, in the case of the
foregoing clauses (A) through (C), (1) each such transferee agrees to be bound in writing by the restrictions set forth in this Section 5.05, (2) any such transfer shall not involve a disposition for value and
(3) no public filing or public disclosure shall be required or voluntarily made during the Lock-up Period in connection with any such transfer (other than required filings under Sections 13(d) or 13(g) or
Section 16 of the Exchange Act). 
 (b) The Major Holders agree and consent to the entry of stop transfer instructions with
Parent’s transfer agent and registrar against the transfer of Lock-up Shares except in compliance with the foregoing restrictions. 

ARTICLE 6 

MISCELLANEOUS 

Section 6.01. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns
of each of the parties hereto; provided, however, that any successor or assign of any Holder (a “Permitted Transferee”) or its Permitted Transferees shall only receive the benefit of this Agreement if such successor or
assign: (i) either (A) receives in an in-kind distribution as contemplated by Section 3.04 of this Agreement at least $5.0 million in Registrable Securities, (B) is a
transferee to which the transfer of the benefits, rights and obligations of this Agreement pursuant to this Section 6.01 have been consented to in writing by Parent or (C) is a transferee by will or the laws of descent

 13 

 Section 6.02. Effectiveness; Term. This Agreement shall be valid and enforceable
as of the date of this Agreement and may not be revoked by any party hereto; provided that the provisions herein (other than this Article 6) shall not be effective until the consummation of the First Merger. In the event the Merger
Agreement is terminated in accordance with its terms prior to the consummation of the First Merger, this Agreement shall automatically terminate and be of no further force or effect. This Agreement shall terminate upon the date as of which all of
the Registrable Securities have been sold, transferred, disposed of or exchanged pursuant to a registration statement (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and SEC Rule 174
thereunder (or any successor rule promulgated thereafter by the SEC)). The provisions of Article 4 shall survive any termination. 

Section 6.03. Governing Law; Waiver of Jury Trial. 

(a) This Agreement shall be governed by and construed in accordance with the law of the State of Delaware, without regard to the conflicts of
law rules of such state that would cause the law of any other jurisdiction to apply.

or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought exclusively in the Court of Chancery of the State of Delaware;
provided that if such court does not have jurisdiction, any such action shall be brought exclusively in the United States District Court for the District of Delaware or any other state court sitting in the State of Delaware, so long as such
courts shall have subject matter jurisdiction over such suit, action or proceeding, and that any cause of action arising out of this Agreement shall be deemed to have arisen from a transaction of business in the State of Delaware, and each of the
parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it
may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit,
action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in
Section 6.06 shall be deemed effective service of process on such party. 
 (c) EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

counterparts. Each such counterpart shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective in accordance with Section 6.02

Section 6.07. Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement
may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of Parent and the Holders of a majority of the Registrable Securities then outstanding; provided that no
such amendment, modification or waiver that would materially and adversely affect a Holder or group of Holders in a manner different than any other Holder or group of Holders shall be effective against such Holder or group of Holders without the
consent of the Holders holding a majority of the Registrable Securities that are held by the group of Holders that is materially and adversely affected thereby, and any provision hereof may be waived by any waiving party on such party’s own
behalf, without the consent of any other party. Notwithstanding the foregoing, this Agreement may not be amended or terminated and the observance of any term hereof may not be waived with respect to any Holder without the written consent of such
Holder, unless such amendment, termination, or waiver applies to all Holders in the same fashion; provided that, without the consent of Bain Capital Credit, LP, Parent shall not waive the provisions of Section 5.05
with respect to any Major Holder. Parent shall give prompt notice of any amendment or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, termination, or waiver. Any amendment, termination,
or waiver effected in accordance with this Section 6.07 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition, or provision of
this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision. 

Section 6.08. Severability. Each term, provision, covenant and restriction of this Agreement is severable. If any such term,
provision, covenant or restriction is held by a court of competent jurisdiction to be invalid, void or unenforceable, (a) it shall have no effect in that respect and the parties shall use all reasonable efforts to replace it in that respect
with a valid and enforceable substitute term, provision, covenant or restriction (as applicable), the effect of which is as close to its intended effect as possible; and (b) the remainder of the terms, provisions, covenants and restrictions of
this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any
party. 
 Section 6.09. Aggregation of Stock. All shares of Registrable Securities held or acquired by Affiliates, including as
may be acquired in connection with a transfer from a Holder party hereto, shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and such Affiliated persons may apportion such rights as among
themselves in any manner they deem appropriate. 

  
 15 

 Section 6.10. Entire Agreement. This Agreement, the Merger Agreement and the
other related agreements as to which Parent, on the one hand, and any Holder on the other hand, are parties, constitute the entire agreement among the parties relating to the transactions contemplated hereby and supersede any other agreements,
whether written and oral, that may have been entered into by or among any of the parties hereto relating to the transactions contemplated hereby. 

Section 6.11. Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party under this
Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach
or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this
Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

Date, the Stockholder shall not, and shall cause its controlled Affiliates and Subsidiaries not to and shall use its reasonable best efforts to cause its and their respective Representatives acting on their respective behalf, not to, directly or
indirectly, and in each case except to the extent the Company is permitted to do so under the Merger Agreement: (A) initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or requests for information with respect to, or
the making of, any inquiry regarding, or any proposal or offer that constitutes, or could reasonably be expected to result in or lead to, any Acquisition Proposal with respect to the Company; (B) engage in, continue or otherwise participate in
any negotiations or discussions concerning, or provide access to its properties, books and records or any confidential information or data to, any Person relating to any proposal, offer, inquiry or request for information that constitutes, or could
reasonably be expected to result in or lead to, any Acquisition Proposal with respect to the Company; (C) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any Acquisition Proposal with respect to the Company;

it shall, and shall cause each of its controlled Affiliates and Subsidiaries and shall use its reasonable best efforts to cause its and their Representatives acting on its or their respective behalf to, cease any solicitations, discussions or
negotiations with any Person (other than Parent and its Representatives) conducted heretofore in connection with an Acquisition Proposal with respect to the Company or any inquiry or request for information that could reasonably be expected to lead
to, or result in, an Acquisition Proposal with respect to the Company. The Stockholder shall promptly (and in any event within two Business days) notify, in writing, Parent of the receipt by the Stockholder in such capacity of any inquiry, proposal,
offer or request for information received after the date hereof that constitutes, or could reasonably be expected to result in or lead to, any Acquisition Proposal with respect to the Company, which notice shall include the identity of the Person or
group of Persons making, such inquiry, proposal, offer or request for information and, with respect to any such proposal or offer, a summary of the material terms of, and an unredacted copy of any proposed definitive agreement, proposal or offer
made in writing or, if not in writing, a written description of the material terms and conditions of such proposal or offer (and shall include any other material documents evidencing or specifying the terms of such proposal or offer or, to the
extent applicable, inquiry). To the extent the Stockholder is prohibited by a non-disclosure or confidentiality 

  
 7 

 
agreement entered into prior to the date hereof from providing the information set forth in the preceding sentence, the Stockholder shall not be required to provide Parent with the identity of
the Person(s) from which such expression of interest, inquiry or proposal was received. The Stockholder shall not enter into any confidentiality agreement with any Person after the date of this Agreement that prohibits it from complying with the
foregoing obligations. Nothing in this Section 7(a) shall prohibit Stockholder or its Representatives from informing any Person of the existence of the provisions contained in this Section 7(a). 

(b) Irrevocable Proxy. In order to secure the obligations set forth herein, the Stockholder hereby irrevocably appoints
Parent, or any nominee thereof, with full power of substitution and resubstitution, as its true and lawful proxy and attorney-in-fact, only in the event that
such Stockholder does not comply with its obligations in Section 1, to vote or execute written consents with respect to the Stockholder’s Covered Shares in accordance with Section 1 and with respect to any proposed
postponements or adjournments of any meeting of the stockholders of the Company at which any of the matters described in Section 1 are to be considered. The Stockholder hereby affirms that this proxy is coupled with an interest and
shall be irrevocable, except upon termination of this Agreement, and the Stockholder will take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy and hereby revokes any proxy previously
granted by such Stockholder with respect to any of its Covered Shares that is materially inconsistent with the Stockholder’s obligations pursuant to this Agreement. This proxy shall be revoked automatically upon the termination of this
Agreement pursuant to Section 3, and Parent may terminate this proxy at any time at its sole election by written notice provided to the Stockholder. 

(c) The Stockholder hereby authorizes the Company to maintain a copy of this Agreement at either the executive office or the
registered office of the Company. 
 8. HSR Act. The Stockholder will use reasonable best efforts to cooperate with the Company and
Parent with respect to any notification form required pursuant to the HSR Act in connection with the Transactions, including with respect to providing information requested by any Governmental Authority with respect thereto. The parties hereto agree
that all filing fees associated with filings made with Governmental Authorities pursuant to this Section shall be treated as Transaction Expenses under the Merger Agreement, subject to applicable limitations set forth in the Merger Agreement. 

9. Termination of Certain Agreements. The Stockholder hereby agrees to execute and deliver such additional documents and take all such
further action as may be reasonably necessary to cause each of the (a) the Registration Rights Agreement, dated December 30, 2016, among the Company and each of the Persons identified therein, (b) the Registration Rights Agreement
dated November 6, 2015, among the Company, FBR Capital Markets & Co., EIG (as defined therein) and Sankaty (as defined therein) (as extended and amended on November 6, 2015) and (c) the Registration Rights Agreement, dated
November 6, 2015, between the Company and EnVen Equity Holdings, LLC to be (to the extent the Stockholder is a party thereto), contingent upon (i) the occurrence of the Closing and (ii) receipt of approval of the requisite parties
(including the Company), terminated without any further force and effect effective immediately prior to the First Effective Time, and the Stockholder hereby agrees to the waiver of any rights of first refusal, preemptive rights, rights of co-sale, and registration rights with respect to the Transactions. 

  
 8 

 10. Further Assurances; Waiver of Appraisal Rights. From time to time, at
Parent’s or the Company’s request and without further consideration, the Stockholder shall execute and deliver such additional documents, including the Registration Rights Agreement, and take all such further action as may be reasonably
necessary or reasonably requested to effect the actions and consummate the transactions contemplated by this Agreement and the Merger Agreement. The Stockholder further agrees, without limiting remedies for fraud, not to commence or participate in,
and to take all actions reasonably necessary to opt out of any class in any class action with respect to, any action or claim, derivative or otherwise, against Parent, the Company or any of their respective Affiliates, successors and assigns
relating to the negotiation, execution or delivery of this Agreement, the Merger Agreement (including the Per Share Consideration, or alleging a breach of any duty of the Company Board or Parent Board in connection with the Merger Agreement, this
Agreement or the transactions contemplated hereby or the Transactions) or the consummation of the transactions contemplated hereby and the Transactions. The Stockholder hereby irrevocably and unconditionally waives, and agrees not to exercise,
assert or perfect (or attempt to exercise, assert or perfect), any rights of appraisal or rights to dissent in connection with the First Merger or the other Transactions that the Stockholder may at any time have under applicable Law by virtue of
ownership of the Covered Shares. 
 11. Disclosure. The Stockholder hereby authorizes the Company and Parent to publish and disclose
in any announcement or disclosure required by the SEC the Stockholder’s identity and ownership of the Covered Shares and the nature of the Stockholder’s obligations under this Agreement; provided, that prior to any such publication
or disclosure the Company and Parent have provided the Stockholder with a reasonable opportunity to review and comment upon such announcement or disclosure, which comments the Company and Parent will consider in good faith. 

12. Changes in Capital Stock. In the event of a stock split, stock dividend or distribution, or any change in the Company’s
capital stock by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, exchange of shares or the like, the terms “Owned Shares,” and “Covered Shares”
shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be converted, changed or exchanged or which are received in such
transaction. 
 13. Amendment and Modification. This Agreement may not be amended, modified or supplemented in any manner, whether by
course of conduct or otherwise, except by an instrument in writing signed by each of the parties hereto. No failure or delay by any party hereto exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the parties hereto hereunder are cumulative and are not exclusive of any rights or
remedies which they would otherwise have hereunder. Any agreement on the part of a party hereto to any such waiver shall be valid only if set forth in a written instrument executed and delivered by such party.
