2.                 
 Amendment to Section 1(a). Section 1(a) of the Existing Agreement is hereby
amended and restated as follows:


 


Registration Statement
Covering Resale of Registrable Securities. Pubco filed with the Commission a Registration Statement on Form S-1 (“Form
S-1”) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering
the resale from time to time by the Investors of all of the Registrable Securities held by the Investors (other than OEP and the
Target Investors) (the “Existing Resale Shelf Registration Statement”). Pubco shall use reasonable best efforts
to keep the Existing Resale Shelf Registration Statement continuously effective to be supplemented and amended to the extent necessary
to ensure that such Existing Resale Shelf Registration Statement is available or, if not available, to ensure that another Registration
Statement is available (which replacement Registration Statement shall be deemed an Existing Resale Shelf Registration Statement),
under the Securities Act at all times until such date as all Registrable Securities covered by the Existing Resale Shelf Registration
Statement, including the Registrable Securities held by the OEP Parties and the Target Investors to be added to the Existing Resale
Shelf Registration Statement in accordance with Section 1(b) or 1(f), as applicable, have been disposed of in accordance
with the intended method(s) of distribution set forth in such Registration Statement or such securities have been withdrawn (the
 “Effectiveness Period”); provided, that Pubco may amend the Existing Resale Shelf Registration Statement in
accordance with Section 1(b), Section 1(d) and Section 1(f), as applicable. Without limiting the foregoing
or any of Pubco’s obligations under this Agreement, the Company will take such actions, including filing supplements to the
prospectus included in such Registration Statement, as shall be necessary to ensure that the Existing Resale Shelf Registration
Statement remains effective and available for the resale of all of the shares of Common Stock issuable upon conversion or otherwise
in respect of any Series B-1 Preferred Stock (in addition to all of the other Registrable Securities covered by the Existing Resale
Shelf Registration Statement) in accordance with the plan of distribution set forth therein. The Existing Resale Shelf Registration
Statement shall contain a Prospectus in such form as to permit any Investor to sell such Registrable Securities pursuant to Rule
415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning
on the effective date for such Registration Statement (subject to lock-up restrictions provided in this Agreement and in the Lock-Up
Agreements), and shall provide that such Registrable Securities may be sold pursuant to any method or combination of methods legally
available to, and requested by, the Investors; provided, that Pubco may amend the Existing Resale Shelf Registration Statement
in accordance with Section 1(b), Section 1(c), Section 1(d), Section 1(e), Section 1(f) or Section
1(g).

3.                 
Amendment to Section 1(f). Section 1(f) of the Existing Agreement is hereby
moved to Section 1(h), and a new Section 1(f) is hereby added as follows:


 


Pubco shall use its
reasonable best efforts to prepare and file or cause to be prepared and filed with the SEC no later than the date that is
sixty (60) days prior to the six month anniversary of the Apollo Closing Date, either, at the sole discretion of Pubco, (x) a
Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 of the Securities Act (provided,
that such Registration Statement replaces and becomes the Existing Resale Shelf Registration Statement) or (y) an amendment
or prospectus supplement to the Existing Resale Shelf Registration Statement registering the resale from time to time by the
Target Investor Parties of all of the Registrable Securities held by the Target Investor Parties (such Registration
Statement, as amended, the “Merger Resale Shelf Registration Statement”); provided, that it is
understood and agreed that the registration of such shares prior to the Restricted Period Termination Date (as defined in the
Apollo Merger Agreement) shall not affect the restrictions on transfer applicable to Prohibited Shares set forth in Section
6.13(a) of the Apollo Merger Agreement. The Merger Resale Shelf Registration Statement shall be on Form S-3 or, if Form S-3
is not then available to Pubco, on Form S-1 or such other appropriate form permitting Registration of the Registrable
Securities for resale by the Target Investor Parties. The Merger Resale Shelf Registration Statement shall contain a
Prospectus in such form as to permit the Target Investor Parties to sell the Registrable Securities pursuant to Rule 415
under the Securities Act (or any successor or similar provision adopted by the SEC then in effect) at any time beginning on
the effective date for the Merger Resale Shelf Registration Statement (subject to the lock-up or transfer restrictions
pursuant to Section 6.13(a) of the Apollo Merger Agreement, as affirmed in any letter of transmittal or support agreement
delivered in connection therewith, and in this Agreement), and shall provide that the Registrable Securities held by the
Target Investor Parties may be sold pursuant to any method or combination of methods legally available to, and requested by,
the holders of a majority of the Registrable Securities held by all Target Investor Parties (the “Target Investor
Majority”). Pubco shall use its reasonable best efforts to cause the Merger Resale Shelf Registration Statement to
be declared effective as soon as possible after filing, but in no event later than the six month anniversary of the Apollo
Closing Date. Without limiting any of the foregoing provisions of this Section 1(f), as soon as practicable, but in no
event later than five (5) business days, following the resolution or clearance of all SEC comments or, if applicable,
following notification by the SEC that any such Registration Statement or any amendment thereto will not be subject to
review, Pubco shall file a request for acceleration of effectiveness of such Registration Statement (to the extent required,
by declaration or ordering of effective, of such Registration Statement or amendment by the SEC) to a time and date not later
than two (2) business days after the submission of such request. No later than two (2) business days after the Registration
Statement becomes effective, Pubco shall file with the SEC the final prospectus included in the Registration Statement
pursuant to Rule 424 (or successor thereto) under the Securities Act. Once effective, Pubco shall use its reasonable best
efforts to keep the Merger Resale Shelf Registration Statement continuously effective and in compliance with the Securities
Act and useable for the resale of the Registrable Securities covered by the Merger Resale Shelf Registration Statement,
including by filing successive replacement or renewal Merger Resale Shelf Registration Statements upon the expiration of the
Merger Resale Shelf Registration Statement, until such time as the Target Investor Parties no longer hold Registrable
Securities. The Target Investor Parties shall be entitled, at any time and from time to time when the Merger Resale Shelf
Registration Statement is effective (subject to the lock-up or transfer restrictions pursuant to Section 6.13(a) of the
Apollo Merger Agreement, as affirmed in any letter of transmittal or support agreement delivered in connection therewith, and
in this Agreement), to sell any or all of the Registrable Securities covered by the Merger Resale Shelf Registration
Statement. Pubco shall pay all Registration Expenses in connection with the filing of the Merger Resale Shelf Registration
Statement.

4.                 
Amendment to Section 1(g). A new Section 1(g) is hereby added as follows:


 


Each transferee of
a Target Investor Party that qualifies as a Target Investor Party (without taking into account the proviso thereto) will be
provided the opportunity, in connection with such transfer, to execute a Joinder to this Agreement that would entitle it to
the benefits of this Agreement as are applicable to a Target Investor Party, and upon the execution and delivery thereof
shall be deemed a Target Investor Party hereunder. Subject to applicable securities laws, Pubco agrees to provide in the
Merger Resale Shelf Registration Statement (and in any prospectus or prospectus supplement forming a part of such Merger
Resale Shelf Registration Statement) that all such transferees shall, by virtue of receiving Registrable Securities in a
Permitted Transfer, be deemed to be selling stockholders under the Merger Resale Registration Statement (or any such
prospectus or prospectus supplement) with respect to such Registrable Securities. If any Target Investor Party becomes a
holder of Registrable Securities after the Merger Resale Shelf Registration Statement is declared effective in accordance
with Section 1(f), then Pubco shall, as promptly as is reasonably practicable following delivery of written notice to
Pubco of such Target Investor Party becoming a holder of Registrable Securities and requesting for its name to be included as
a selling securityholder in the Prospectus related to the Merger Resale Shelf Registration Statement:


 


(i)               if
required and permitted by applicable law, file with the Commission a supplement to the related Prospectus or a post-effective
amendment to the Merger Resale Shelf Registration Statement so that such Target Investor Party is named as a selling securityholder
in the Merger Resale Shelf Registration Statement and the related Prospectus in such a manner as to permit such Target Investor
Party to deliver a prospectus to purchasers of the Registrable Securities in accordance with applicable law; provided, however,
that Pubco shall not be required to file more than one post-effective amendment or a supplement to the related prospectus for
under this Section 1(g) in any 45-day period;


 


(ii)              if,
pursuant to Section 1(g)(i), Pubco shall have filed a post-effective amendment to the Merger Resale Shelf Registration
Statement that is not automatically effective, use its reasonable best efforts to cause such post-effective amendment to become
effective under the Securities Act as promptly as is reasonably practicable; and


 


(iii)             notify
such Target Investor Party as promptly as is reasonably practicable after the effectiveness of any post-effective amendment filed
pursuant to Section 1(g)(i).


 


5.                 
Amendment to Section 2(b). Section 2(b) of the Existing Agreement is hereby
amended and restated as follows:


 


Long-Form
Registrations. (i) The OEP Parties may request an aggregate of three (3), (ii) the Target Investor Majority may request
an aggregate of three (3), (iii) the Deerfield Parties may request an aggregate of one (1) and (iv) the Investors (other than
any OEP Parties and the Target Investors) holding a majority of the Registrable Securities (other than those held by the OEP
Parties and the Target Investors) may request an aggregate of one (1) Long-Form Registration in which Pubco shall pay all
Registration Expenses whether or not any such Long-Form Registration has become effective; provided that, Pubco shall not be
obligated to effect, or to take any action to effect, any Long-Form Registration unless the aggregate market price of the
Registrable Securities requested to be registered in such Long-Form Registration exceeds $20,000,000 at the time of request;
provided, further, that Pubco shall only be obligated to effect, or take any action to effect, three (3) Long-Form
Registrations in the case of any request therefor by any of the OEP Parties, three (3) Long-Form Registrations in the case of
any request therefor by the Target Investor Majority, one (1) Long-Form Registrations in the case of any request therefor by
any of the Deerfield Parties and one (1) Long-Form Registration in the case of any request therefor by Investors (other than
any OEP Parties and the Target Investors) holding a majority of the Registrable Securities (other than those held by the OEP
Parties and the Target Investors). A registration shall not count as a permitted Long-Form Registration until it has become
effective and unless the holders of Registrable Securities are able to register and sell at least 90% of the Registrable
Securities requested to be included in such registration; provided that in any event Pubco shall pay all Registration
Expenses in connection with any registration initiated as a Long-Form Registration whether or not it has become effective and
whether or not such registration has counted as one of the permitted Long-Form Registrations hereunder.

6.                 
Amendment to Section 2(c). Section 2(c) of the Existing Agreement is hereby
amended and restated as follows:


 


Short-Form Registrations.
In addition to the Long-Form Registration provided pursuant to Section 2(b), each of (i) the Investors holding a majority
of the Common Units not held by Pubco, (ii) the Investors holding a majority of the Founder Shares, (iii) the Investors holding
a majority of the PIPE Shares (including any Common Stock issuable in respect of any Series B-1 Preferred Stock that was exchanged
for PIPE Shares), (iv) the Deerfield Parties, (v) the Target Investor Majority and (vi) the OEP Parties, in each case, shall be
entitled to request an unlimited number of Short-Form Registrations in which Pubco shall pay all Registration Expenses whether
or not any such Short-Form Registration has become effective; provided, however, that Pubco shall not be obligated to effect any
such Short-Form Registration: (i) if the holders of Registrable Securities, together with the holders of any other securities of
Pubco entitled to inclusion in such Short-Form Registration, propose to sell Registrable Securities with an aggregate market price
at the time of request of less than $5,000,000, or (ii) if Pubco has, within the twelve (12) month period preceding the date of
such request, already effected three (3) Short-Form Registrations for the holders of Registrable Securities requesting a Short-Form
Registration pursuant to this Section 2(c). Demand Registrations shall be Short-Form Registrations whenever Pubco is permitted
to use any applicable short form registration and if the managing underwriters (if any) agree to the use of a Short-Form Registration.
For so long as Pubco is subject to the reporting requirements of the Exchange Act, Pubco shall use its reasonable best efforts
to make Short-Form Registrations available for the offer and sale of Registrable Securities. If Pubco is qualified to and, pursuant
to the request of the holders of a majority of the Registrable Securities, has filed with the Commission a registration statement
under the Securities Act on Form S-3 pursuant to Rule 415 (a “Shelf Registration”), then Pubco shall use its
reasonable best efforts to cause the Shelf Registration to be declared effective under the Securities Act as soon as practicable
after filing, and, if Pubco is a WKSI at the time of any such request, to cause such Shelf Registration to be an Automatic Shelf
Registration Statement, and once effective, Pubco shall cause such Shelf Registration to remain effective (including by filing
a new Shelf Registration, if necessary) for a period ending on the earlier of (i) the date on which all Registrable Securities
included in such registration have been sold or distributed pursuant to the Shelf Registration or (ii) the date as of which all
of the Registrable Securities included in such registration are able to be sold within a 90-day period in compliance with Rule
144 under the Securities Act. If for any reason Pubco ceases to be a WKSI or becomes ineligible to utilize Form S-3, Pubco shall
prepare and file with the Commission a registration statement or registration statements on such form that is available for the
sale of Registrable Securities.


 


7.                 
 Amendment to Section 2(d). Section 2(d) of the Existing Agreement is hereby
amended to include “, the Merger Resale Shelf Registration Statement” after “the Deerfield Resale Shelf Registration
Statement”.


 






    5


     


    

 


8.                 
Amendment to Section 2(f)(i). Section 2(f)(i) of the Existing Agreement
is hereby amended and restated as follows:


 


Pubco shall not be
obligated to effect any Demand Registration within 30 days prior to Pubco’s good faith estimate of the date of filing of
an underwritten Public Offering of Pubco’s securities and for such a period of time after such a filing as the managing underwriters
request, provided that such period shall not exceed 90 days from the effective date of any such underwritten Public Offering. Pubco
may postpone, for up to 60 days from the date of the request (the “Suspension Period”), the filing or the effectiveness
of a registration statement for a Demand Registration or suspend the use of a prospectus that is part of any Resale Shelf Registration
(and therefore suspend sales of the Registrable Securities included therein) by providing written notice to the holders of Registrable
Securities if the board of directors of Pubco reasonably determines in good faith that the offer or sale of Registrable Securities
would be expected to have a material adverse effect on any proposal or plan by Pubco or any subsidiary thereof to engage in any
material acquisition or disposition of assets or stock (other than in the ordinary course of business) or any material merger,
consolidation, tender offer, recapitalization, reorganization or similar transaction or would require Pubco to disclose any material
nonpublic information which would reasonably be likely to be detrimental to Pubco and its subsidiaries; provided that in such event,
the holders of Registrable Securities initially requesting such Demand Registration or Takedown Demand shall be entitled to withdraw
such request. Pubco may delay or suspend the effectiveness of a Demand Registration or the use of a prospectus that is part of
any Resale Shelf Registration (and the sales of the Registrable Securities included therein) pursuant to this Section 2(f)(i) only
once in any consecutive twelve-month period; provided that, for the avoidance of doubt, Pubco may in any event delay or suspend
the effectiveness of such Demand Registration or the use of such prospectus that is part of any Resale Shelf Registration (and
such sales of Registrable Securities included therein) in the case of an event described under Section 5(g) to enable it to comply
with its obligations set forth in Section 5(f). Pubco may extend the Suspension Period for an additional consecutive 60 days with
the consent of the Applicable Approving Party.


 


9.                 
Amendment to Section 3(a). Section 3(a) of the Existing Agreement is hereby
amended to include “, Merger Resale Shelf Registration Statement” after “OEP Resale Shelf Registration Statement”.


 


10.             
Amendment to Section 3(e). Section 3(e) of the Existing Agreement is hereby
amended and restated as follows:


 


Entire
Agreement; Effectiveness. If Pubco has previously filed a Registration Statement with respect to Registrable Securities
pursuant to Section 2 or pursuant to this Section 3, and if such previous registration has not been withdrawn
or abandoned, then Pubco shall not be required to file or cause to be effected any other registration of any of its equity
securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act
(except on Form S-8 or any successor form) at the request of any holder or holders of such securities until a period of at
least 90 days has elapsed from the effective date of such previous registration; provided, however, that Pubco shall at all
times remain obligated to file or amend, as applicable, (i) any OEP Resale Shelf Registration Statement in accordance with Section
1(b) and/or Section 1(c) in the time periods specified therein, (ii) any Deerfield Resale Shelf Registration
Statement in accordance with Section 1(d) and/or Section 1(e) in the time periods specified therein and (iii)
any Merger Resale Shelf Registration Statement in accordance with Section 1(f) and/or Section 1(g) in the time
periods specified therein.


 


11.             
Amendment to Section 5. Section 5 of the Existing Agreement is hereby amended
to include “, Merger Resale Shelf Registration Statement” after “OEP Resale Shelf Registration Statement”.



 






    6


     


    

 


12.

(b)

to whom 300,000 or more shares of Registrable Securities (on an as converted basis) are transferred pursuant to Section 6.13 of
the Apollo Merger Agreement; provided, that, in each case of clause (ii) and (iii), such transferee executes a Joinder to this
Agreement in connection with such transfer as contemplated Section 1(g) of this Agreement.

one and the same instrument; provided that in the event that any signature is delivered by facsimile transmission or by
e-mail delivery of a .pdf format data file, such signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if such facsimile or .pdf signature were the original
thereof.


 


17.             
Choice of Law. This Amendment is governed by the laws of the State of Delaware, without
regard to its conflict of laws provisions.
