holders of at least a majority-in-interest of the then-outstanding number of Registrable Securities held by the Apache Holders may make a written demand for Registration
of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand
Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Apache Holders of Registrable Securities of such demand, and each Apache Holder of
Registrable 

  
 7 

 
Securities who thereafter wishes to include all or a portion of such Apache Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Apache Holder that
includes all or a portion of such Apache Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Apache
Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a
Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of
all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. 
 2.1.2
Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the
Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any)
to include its 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 such Underwritten Offering to the
extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.2 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the Company by the majority-in-interest of the Demanding Holders initiating the Demand Registration. 

2.1.3 Shelf Registration. The Company shall, as soon as practicable after the Contribution Closing Date, but in any event within thirty
(30) days after the Contribution Closing Date, file a Registration Statement under the Securities Act to permit the public resale of all the Registrable Securities held by the Holders from time to time as permitted by Rule 415 under the
Securities Act (or any successor or similar provision adopted by the Commission then in effect) on the terms and conditions specified in this subsection 2.1.3 and shall use its commercially reasonable efforts to cause such
Registration Statement to be declared effective as soon as practicable after the filing thereof, but in any event no later than the earlier of (i) ninety (90) days (or one hundred and twenty (120) days if the Commission notifies the
Company that it will “review” the Registration Statement) after the Contribution Closing Date and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission
that such Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”). The Registration Statement filed with the Commission pursuant to
this subsection 2.1.3 shall be on Form S-3 or similar short form registration statement that may be available at such time (“Form
S-3”), or, if Form S-3 is not then available to the Company, on Form S-1 (“Form S-1”) or on such other form of registration statement as is then available to effect a Registration for resale of the Registrable Securities; provided, however, that if the Company has
filed the Registration Statement on Form S-1 and subsequently becomes eligible to use Form S-3 or any equivalent or successor form, the Company shall (i) file a
post-effective amendment to the Registration Statement converting such Registration Statement on Form S-1 to a Registration Statement on Form S-3 or any equivalent

  
 8 

 
or successor form or (ii) withdraw the Registration Statement on Form S-1 and file a subsequent Registration Statement on Form S-3 or any equivalent or successor form, and shall contain a Prospectus in such form as to permit any Existing Holder 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. A Registration Statement filed pursuant to this subsection 2.1.3 shall provide for the
resale pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall use its reasonable best efforts to cause a Registration Statement filed pursuant to this subsection 2.1.3 to remain
effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available, for the resale of all the Registrable Securities
held by the Holders until all such Registrable Securities have ceased to be Registrable Securities or the earlier termination of this Agreement pursuant to Section 5.7. As soon as practicable following the effective date of
a Registration Statement filed pursuant to this subsection 2.1.3, but in any event within three (3) business days of such date, the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a
Registration Statement filed pursuant to this subsection 2.1.3 (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 a Misstatement (in the case of any Prospectus contained in such Registration Statement, in the light of the circumstances under which such statement is made). 

2.1.4 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Offering pursuant to a Demand
Registration, in good faith, advises the Company, the Demanding Holders, and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire
to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell, and the Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back
registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in such Underwritten Offering without adversely affecting the proposed offering price,
the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall
include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and Requesting Holders (if any) (if such amount exceeds the Maximum Number of Securities, pro rata based on the respective number
of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have
requested be included in such Underwritten Offering) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the
Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the

so withdraw at any time prior to (x) in the case of a Demand Registration not involving any Underwritten Offering, the effectiveness of the applicable Registration Statement or (y) in the case of any Demand Registration involving an
Underwritten Offering, prior to the pricing of such Underwritten Offering; provided, however, that upon withdrawal by a majority-in-interest of the Demanding Holders

offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the

(ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan,

Registration and shall use its reasonable best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Apache Holders pursuant to this subsection
2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance
with the intended method(s) of distribution thereof. All such Apache Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in

Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant Section 2.1.2 hereof, and (iii) the Common Stock, if any, as to which Registration

each Apache Holder has requested be included in such Piggyback Registration and the aggregate number of Registrable Securities that the Apache Holders have requested be included in such Piggyback Registration), which can be sold without exceeding
the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration has been requested
pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3; provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering, unless such Underwritten Offering is reasonably expected to result in gross
proceeds in excess of $10 million. Within five (5) days of the Company’s receipt of a written request from an Apache Holder or Apache Holders of Registrable Securities for a Registration on Form
S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Apache Holders of Registrable Securities, and each Apache
Holder of Registrable Securities who thereafter wishes to include all or a portion of such Apache Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing,
within ten (10) days after the receipt by the Apache Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a
Registration on Form S-3, the Company shall register all or such portion of such Apache Holder’s Registrable Securities as are specified in such written request, together with all or such portion of
Registrable Securities of any other Apache Holder or Apache Holders joining in such request as are specified in the written notification given by such Apache Holder or Apache Holders; provided, however, that the Company shall not be obligated to
effect any such Registration pursuant to this Section 2.3 if (i) a Form S-3 is not available for such offering; or (ii) the Apache Holders of Registrable Securities, together with the Holders of
any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $10 million. 

2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the
Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to
the Holders prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively 

  
 12 

 
employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) pursuant to subsection 2.1.2, Holders have requested an
Underwritten Offering and the Company and Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the majority of the Board such Registration would be seriously
detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by
the chairman of the Board stating that in the good faith judgment of the majority of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to
defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days. Notwithstanding anything to the contrary contained in this Agreement, no
Registration shall be effected or permitted and no Registration Statement shall become effective, with respect to any Registrable Securities held by any Existing Holder, until after the expiration of the Founder Shares
Lock-up Period or the Private Placement Lock-up Period, as the case may be. 

ARTICLE III 
 COMPANY
PROCEDURES 
 3.1 General Procedures. If the Company is required to effect the Registration of Registrable Securities, the
Company shall use its reasonable best efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as
possible: 
 3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable
Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities have ceased to be Registrable Securities or the earlier termination of this Agreement
pursuant to Section 5.7; 
 3.1.2 prepare and file with the Commission such amendments and post-effective
amendments to the Registration Statement, and such supplements to the Prospectus, as may be requested by the Holders or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the
registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the
intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus; 
 3.1.3 prior to filing a
Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and one legal counsel to such Holders, copies
of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents 

  
 13 

 
incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of
Registrable Securities included in such Registration or the one legal counsel for such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders; 

3.1.4 prior to any public offering of Registrable Securities, use its reasonable best efforts to (i) register or qualify the Registrable
Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their
intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be
necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or
take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject; 

3.1.5 use its reasonable best efforts to cause all such Registrable Securities to be listed on each securities exchange or automated quotation
system on which similar securities issued by the Company are then listed; 
 3.1.6 provide a transfer agent or warrant agent, as applicable,
and registrar for all such Registrable Securities no later than the effective date of such Registration Statement; 
 3.1.7 advise each
seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or
threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such
Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or one counsel on behalf of such
sellers; 
 3.1.9 notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under
the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in
Section 3.4 hereof; 

  
 14 

 3.1.10 permit a representative of the Holders (such representative to be selected by a
majority of the participating Holders), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such Person’s own expense, in the preparation of the Registration Statement, and
cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such
representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 

3.1.11 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an
Underwritten Offering, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 
 3.1.12 on the
date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated as of such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent
or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request
and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders; 

3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form on terms agreed to by the Company, with the managing Underwriter of such offering; 
 3.1.14 make available to its security
holders, as soon as reasonably practicable, an earnings statement (which need not be audited) covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective
date of the Registration Statement which satisfies the provisions of Section 11 (a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million, use its
reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and 

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in
connection with such Registration. 

  
 15 

 3.2 Registration Expenses. The Registration Expenses of all Registrations shall be
borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter
marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders. 

3.3 Requirements for Participation in Underwritten Offerings. No Person may participate in any Underwritten Offering for equity
securities of the Company unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires,
powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. 

3.4 Suspension of Sales; Adverse Disclosure. 

3.4.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders
shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such
supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed (any such period, a “Suspension Period”). 

3.4.2 If the filing, initial effectiveness or continued use of (including in connection with any Underwritten Offering) a Registration
Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond
the Company’s control, then the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of (including in connection with any Underwritten Offering), such
Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose (any such period, a “Blackout Period”). In the
event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale
or offer to sell Registrable Securities. 
 3.4.3 The Company shall immediately notify the Holders of the expiration of any period during
which it exercised its rights under this Section 3.4. Notwithstanding anything to the contrary in this Section 3.4, in no event shall any Blackout Periods and any Suspension Periods continue for
more than ninety (90) days in the aggregate during any 365-day period. 
 3.5 Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and

  
 16 

 
complete copies of all such filings (the delivery of which will be satisfied by the Company’s filing of such reports on the Commission’s EDGAR system). The Company further covenants
that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall
deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE IV 

INDEMNIFICATION AND CONTRIBUTION 

4.1 Indemnification. 

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors, and
each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact
contained in any Registration Statement, Prospectus, preliminary Prospectus, or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and
directors, and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder. 

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and
officers and agents, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any
untrue statement of material fact contained in the Registration Statement, Prospectus, preliminary Prospectus, or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the
obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such
Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors, and each Person who controls such Underwriters (within the
meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 
  

  
 17 

 4.1.3 Any Person entitled to indemnification herein shall (i) give prompt written
notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not
materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified
party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified
parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and
such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all
liability in respect to such claim or litigation. 
 4.1.4 The indemnification provided for under this Agreement shall remain in full force
and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the Transfer of securities. The Company and each Holder of
Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is
unavailable for any reason. 
 4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying
party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities, and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall
contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities, and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified
party, as well as any other relevant equitable considerations. The relative fault of the 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 to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified
party’s relative intent, knowledge, access to information, and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of
the net proceeds received by 

  
 18 

 
such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include,
subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges, or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties
hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations
referred to in this subsection 4.1.5. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection
4.1.5 from any Person who was not guilty of such fraudulent misrepresentation. 
 ARTICLE V

change of address shall become effective thirty (30) days after delivery of such notice as provided in this Section 5.1. 
 5.2
Assignment; No Third Party Beneficiaries. 
 5.2.1 This Agreement and the rights, duties and obligations of the Company hereunder may
not be assigned or delegated by the Company in whole or in part. 
 5.2.2 Prior to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, no Existing Holder may assign or delegate such Existing Holder’s rights, duties, or
obligations under this Agreement, in whole or in part, except in connection with a Transfer of Registrable Securities by such Existing Holder to a Permitted Transferee. Subject to the foregoing with respect to Existing Holders, no Holder may assign
or delegate such Holder’s rights, duties, or obligations under this Agreement, in whole or in part, except in connection with a Transfer of Registrable Securities by such Holder to a Permitted Transferee. 

  
 19 

 5.2.3 Neither this Agreement nor any right, remedy, obligation, or liability arising
hereunder or by reason hereof shall be assignable by any party hereto pursuant to any Transfer of Registrable Securities or otherwise, except that each Holder may assign rights hereunder to any Permitted Transferee of such Holder. Any such Permitted
Transferee shall (unless already bound hereby) execute and deliver to the Company an agreement (the “Adoption Agreement”) to be bound by this Agreement in the form of Exhibit A hereto and shall thenceforth be a
“Holder”. 
 5.2.4 This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the
parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 
 5.2.5 This Agreement shall
not confer any rights or benefits on any Persons that are not parties hereto, other than as expressly set forth in this Agreement and Section 5.2 hereof. 

5.2.6 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the
Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) an executed Adoption Agreement. Any Transfer or assignment made other than
as provided in this Section 5.2 shall be null and void. 
 5.3 Counterparts. This Agreement may be executed
in multiple counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

5.4 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES
EXPRESSLY AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO
THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THE AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK. 

5.5 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a
majority-in-interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement
may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, (i) any amendment hereto or waiver hereof that adversely affects one Holder,
solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected and (ii) any amendment
hereto or waiver hereof that adversely affects the Existing Holders or the Apache Holders, as applicable, solely in their respective capacity as Existing Holdings or Apache Holders, as applicable, in a manner that is materially different from the
other Holders, shall require the consent of the 

  
 20 

 
Existing Holders or Apache Holders, as applicable, of a majority-in-interest of the then-outstanding number of
Registrable Securities held by the Existing Holders or Apache Holders, as applicable. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any
rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude
the exercise of any other rights or remedies hereunder or thereunder by such party. 
 5.6 Other Registration Rights. Other than
pursuant to the terms of the Subscription Agreements, the Company represents and warrants that no Person, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to
include such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the account of any other Person. Further, the Company represents and warrants that this Agreement supersedes any
other registration rights agreement or agreement with similar terms and conditions among the parties hereto and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. 

5.7 Term. This Agreement shall terminate, and the parties shall have no further rights or obligations hereunder on (a) the fifth
anniversary of the date hereof or (b) as to any Holder, on such earlier date on which both (i) such Holder, together with such Holder’s Affiliates, owns less than 2,000,000 Registrable Securities and (ii) all Registrable
Securities owned by such Holder and such Holder’s Affiliates may be sold without volume or manner of sale restrictions pursuant to Rule 144 under the Securities Act (or any successor or similar rule adopted by the Commission then in effect).
The provisions of Section 3.5 and Article IV shall survive any termination. 
 5.8 Holder Action. Whenever
the Existing Holders or Apache Holders are entitled to act or refrain from acting, the Existing Holders or Apache Holders, as applicable, shall do so by the determination of a
majority-in-interest of the then-outstanding number of Registrable Securities held by the Existing Holders or Apache Holders, as applicable.

Execution Version 

WARRANT AGREEMENT 
 between 

KAYNE ANDERSON ACQUISITION CORP. 

and 
 AMERICAN STOCK
TRANSFER & TRUST COMPANY, LLC 
 THIS WARRANT AGREEMENT (this “Agreement”), dated as of November 9, 2018, is by and
between Kayne Anderson Acquisition Corp., a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC, a New York limited liability trust company, as warrant agent (the
“Warrant Agent”, also referred to herein as the “Transfer Agent”). 
 WHEREAS, the Company is party to that
certain contribution agreement, dated as of August 8, 2018, by and among Apache Midstream LLC, a Delaware limited liability company (“Holder”), and other parties thereto (the “Contribution
Agreement”); and 
 WHEREAS, pursuant to the Contribution Agreement, the Company has determined to issue and deliver 3,182,140 warrants bearing
the legend set forth in Exhibit B hereto to Holder (the “Warrants” and each, a “Warrant”). Each whole Warrant entitles the Holder to purchase one share of Class A common stock of the
Company, par value $0.0001 per share (“Common Stock”), for $11.50 per share, subject to adjustment as described herein; and 

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance,
registration, transfer, exchange, redemption and exercise of the Warrants; and 
 WHEREAS, the Company desires to provide for the form and provisions of the
Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the Holder; and 

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned
by or on behalf of the Warrant Agent, as provided herein, the valid, binding, and legal obligations of the Company, and to authorize the execution and delivery of this Agreement. 

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 

 

	1.	 Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the
Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

  
 1 

	2.	 Warrants. 

2.1 Form of Warrant. Each Warrant shall be issued in registered form only. 

2.2 Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to
this Agreement, a Warrant evidenced by a physical certificate shall be invalid and of no effect and may not be exercised by the holder thereof. 

2.3 Registration. 
 2.3.1.
Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the
Warrants, the Warrant Agent shall issue and register the Warrants in the name of Holder in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the
Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with the Depository Trust Company (the “Depositary”) (such institution, with
respect to a Warrant in its account, a “Participant”). If the Depositary subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making
other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the
Depositary to deliver to the Warrant Agent for cancellation each book-entry Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Warrants which shall be in
the form annexed hereto as Exhibit A. Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer, Chief Financial Officer, Secretary, or
other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be
issued with the same effect as if he or she had not ceased to be such at the date of issuance. 
 2.3.2. Registered Holder. Prior to
due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the
absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on any physical certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any
exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

2.4 No Fractional Warrants. The Company shall not issue fractional Warrants. If a holder of Warrants would be entitled to receive a
fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be issued to such holder. 

  
 2 

 2.5 Permitted Transfers of Warrants. 

2.5.1. So long as they are held by the Holder or any of its Permitted Transferees (as defined below) the Warrants: (i) may be exercised
for cash or on a cashless basis pursuant to subsection 3.3.1(b) hereof, (ii) may not be transferred, assigned or sold until thirty (30) days after the closing of the transactions contemplated by the Contribution Agreement (the
“Contribution Closing” and such period, the “Transfer Restriction Period”) and (iii) shall not be redeemable by the Company. 

2.5.2. Notwithstanding the restrictions contained in Section 2.5.1(i) and
Section 2.5.1(ii), the Warrants and any shares of Common Stock held by the Holder or any of its Permitted Transferees and issued upon exercise of the Warrants may be transferred by the holders thereof: 

(a) in the case of an individual, as a gift to such person’s immediate family or to a trust, the beneficiary of which is a
member of such person’s immediate family, an affiliate of such person or to a charitable organization; 
 (b) to the
Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors, any affiliate of the Holder, or to any partner(s) or member(s) of the Holder or any of their affiliates; 

(c) to officers, directors, or employees of Apache Corporation or any of its affiliates, or any affiliate or family member of
such officer, director, or employee; 
 (d) in the case of an individual, by virtue of the laws of descent and distribution
upon death of such person; 
 (e) in the case of an individual, pursuant to a qualified domestic relations order; 

(f) by virtue of the laws of the state of Delaware or the Holder’s agreement of limited partnership upon dissolution of
the Holder; or 
 (g) in the event that, subsequent to the Contribution Closing, the Company consummates a merger, capital
stock exchange, reorganization or other similar transaction that results in all of the holders of the Company’s equity securities issued in the Company’s initial public offering having the right to exchange their shares of Common Stock for
cash, securities or other property; 
 provided, however, that in the case of clauses (a) through (f), these transferees (the
“Permitted Transferees”) enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement. For the avoidance of doubt, nothing contained in this Agreement shall prohibit the
Holder from transferring Warrants to a Permitted Transferee during the Transfer Restriction Period. The term “Other Transferee” as used in this Agreement shall refer to any transferee other than a Permitted Transferee.
Warrants that are transferred to an Other Transferee shall upon such transfer become subject to redemption pursuant to Section 6.

	3.	 Terms and Exercise of Warrants. 

3.1 Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the
provisions of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided
in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share at which shares
of Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) days
(other than a Saturday, Sunday or federal holiday) on which banks in New York City are generally open for normal business (a “Business Day”), provided, that the Company shall provide at least twenty (20) days prior
written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants. 

3.2 Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing
on the date that is thirty (30) days after the Contribution Closing and terminating at 5:00 p.m., New York City time on the earlier of: (i) the fifth (5th) anniversary of the
date hereof (the “Expiration Date”) or (ii) to the extent a Warrant is transferred to an Other Transferee, the Redemption Date (as defined below), as provided in Section 6.2; provided,
however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below with respect to an effective registration statement. To the extent a Warrant is
transferred to an Other Transferee, except with respect to the right to receive the Redemption Price (as defined below) in the event of a redemption (as set forth in Section 6 hereof), each outstanding Warrant not exercised
on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend
the duration of the Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further
that any such extension shall be identical in duration among all the Warrants. 
 3.3 Exercise of Warrants. 

3.3.1. Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may be
exercised by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, in the Borough of Manhattan, City and State of New York, with the subscription form, as set forth
in the Warrant, duly executed, and by paying in full the Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the
Warrant for the shares of Common Stock and the issuance of such Common Stock, as follows: 
 (a) in lawful money of the
United States, in good certified check or good bank draft payable to the Warrant Agent; 

  
 4 

 (b) in the event of a redemption pursuant
to Section 6 hereof in which the Company’s board of directors (the “Board”) has elected to require holders of Warrants transferred to Other Transferees to exercise such Warrants on a
“cashless basis,” by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the
difference between the Warrant Price and the “Fair Market Value”, as defined in this subsection 3.3.1(b) by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b) and
Section 6.4, the “Fair Market Value” shall mean the average last sale price of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of
redemption is sent to the holders of the Warrants, pursuant to Section 6 hereof; 
 (c) by
surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant
Price and the “Fair Market Value”, as defined in this subsection 3.3.1(c), by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average last
sale price of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which notice of exercise of the Warrant is sent to the Warrant Agent; or 

(d) as provided in Section 7.4 hereof. 

3.3.2. Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the
funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of
Common Stock to which he, she, or it is entitled, registered in such name or names as may be directed by him, her, or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable,
for the number of shares of Common Stock as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Warrant and shall
have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act of 1933, as amended (the “Securities Act”) with respect to the shares of Common Stock underlying the Warrants is then
effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4, or an exemption from such registration is available. No Warrant shall be exercisable and
the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the Common Stock issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt from registration or qualification under
the securities laws of the state of residence of the Registered Holder of the Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be
entitled to exercise such Warrant and such Warrant may have no value and expire worthless. 
 3.3.3. Valid Issuance. All shares of
Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid, and non-assessable. 

  
 5 

 3.3.4. Date of Issuance. Each person in whose name any book-entry position or
certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant,
was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books
of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the share transfer books or
book-entry system are open. 
 3.3.5. Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it
elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she, or it makes such election. If the election
is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with
such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (as specified by the holder) (the “Maximum Percentage”) of the shares of Common Stock outstanding
immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common Stock issuable
upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant
beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without
limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this
paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of
outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly
report on Form 10-Q, current report on Form 8-K, or other public filing with the Securities and Exchange Commission (the “Commission”)
as the case may be, (2) a more recent public announcement by the Company, or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the
written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of
Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By
written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such
increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company. 

  
 6 

	4.	 Adjustments. 

4.1 Stock Dividends. 

4.1.1. Split-Ups. If after the date hereof, and subject to the provisions of
Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or
other similar event, then, on the effective date of such stock dividend, split-up, or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion
to such increase in the outstanding shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price less than the “Fair Market Value” (as defined below) shall be
deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering
that are convertible into or exercisable for the Common Stock) and (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the Fair Market Value. For purposes of this
subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into account any consideration
received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading day
period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. 

4.1.2. Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or
make a distribution in cash, securities, or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than
(a) as described in subsection 4.1.1 above or (b) Ordinary Cash Dividends (as defined below) (any such non-excluded event being referred to herein as an “Extraordinary
Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Board, in good faith) of any
securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash
distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of
declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that
resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not exceed $0.10. 

4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions
of Section 4.6 hereof, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split, or reclassification of shares of Common Stock or other similar event,
then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in
outstanding shares of Common Stock. 

  
 7 

 4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock
purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such
Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the
denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 
 4.4 Replacement of Securities
upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change under subsections
4.1.1 or 4.1.2 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into
another entity or conversion of the Company as another entity (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of
Common Stock), or in the case of any sale or conveyance to another entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants
shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger, or consolidation, or upon a dissolution following any
such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her, or its Warrant(s) immediately prior to such event (the “Alternative Issuance” ) and the Company shall not
enter into any such consolidation, merger, sale, or conveyance unless the successor or purchasing entity, as the case may be, shall execute an amendment hereto with the Warrant Agent providing for delivery of such Alternative
Issuance; provided, however, that (i) if the holders of the Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash, or other assets receivable upon such consolidation or
merger, then the kind and amount of securities, cash, or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the
holders of the Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange, or redemption offer shall have been made to and accepted by the holders of the Common Stock under circumstances
in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor
rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any successor rule)) and any members of any
such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of
Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, 

  
 8 

 
securities, or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or
exchange offer, accepted such offer, and all of the Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly
equivalent as possible to the adjustments provided for in this Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is
payable in the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter
market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable
event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (but in no event less than
zero) (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant
Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (“Bloomberg”).
For purposes of calculating such amount, (1) Section 6 of this Agreement shall be taken into account, (2) the price of each share of Common Stock shall be the volume weighted average price of the Common Stock as
reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (3) the assumed volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg determined
as of the trading day immediately prior to the day of the announcement of the applicable event, and (4) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant.
“Per Share Consideration” means (i) if the consideration paid to holders of the Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock and (ii) in all other cases, the volume
weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in
shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3, and this Section 4.4. The provisions
of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales, or other transfers. In no event will the Warrant Price be reduced to less than the par value per
share issuable upon exercise of the Warrant. 
 4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the
number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any,
in the number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event
specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the
record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 

  
 9 

 4.6 No Fractional Shares. Notwithstanding any provision contained in this Agreement
to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled,
upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder. 

4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to
this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this
Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any
Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 

4.8 Other Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of
this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and
purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking, or other appraisal firm of recognized national standing, which shall give its
opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary, the
terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 
  

	5.	 Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the
Warrant Register, upon surrender of such Warrant for transfer, in the case of certificated warrants, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new
Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the
Company from time to time upon request. 
 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent,
together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate
number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the
Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 

  
 10 

 5.3 Fractional Warrants. The Warrant Agent shall not be required to effect any

	6.	 Redemption. 

6.1 General. For the avoidance of doubt, this Section 6 shall apply only to Warrants transferred to an Other
Transferee. 
 6.2 Redemption. Each outstanding Warrant that has been transferred to an Other Transferee may be redeemed, at the
option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of such Warrants that have been transferred to an Other Transferee, as described
in Section 6.3 below, at the price of $0.01 per Warrant (the “Redemption Price”), provided that the last sales price of the Common Stock reported has been at least
$18.00 per share (subject to adjustment in compliance with Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending
on the third Business Day prior to the date on which notice of the redemption is given and provided that there is an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current
prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below) or the Company has elected to require the exercise of the
Warrants on a “cashless basis” pursuant to subsection 3.3.1. 
 6.3 Date Fixed for, and Notice of, Redemption.
In the event that the Company elects to redeem Warrants that have been transferred to an Other Transferee, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first
class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Warrants
to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice.

  
 11 

 6.4 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or
on a “cashless basis” in accordance with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.3 hereof and prior to the
Redemption Date. In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption shall contain the information
necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the
Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 
  

	7.	 Other Provisions Relating to Rights of Holders of Warrants. 

7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of
directors of the Company or any other matter. 
 7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen,
mutilated, or destroyed, the Company and the Warrant Agent shall on such terms as to indemnity or otherwise as they may in their reasonable discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a
new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen,
mutilated, or destroyed Warrant shall be at any time enforceable by anyone. 
 7.3 Reservation of Common Stock. The Company shall at
all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

7.4 Registration of Common Stock; Cashless Exercise at Company’s Option. 

7.4.1. Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen
(15) Business Days after the Contribution Closing, it shall use its best efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the shares of Common Stock issuable upon exercise of the
Warrants. The Company shall use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance
with the provisions of this Agreement. If any such registration statement has not been declared effective by the 60th Business Day following the Contribution Closing, holders of the Warrants shall have the right, during the period beginning on the
61st Business Day after the Contribution Closing and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement
covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act (or any successor
rule) or another exemption) for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock 

  
 12 

 
underlying the Warrants, multiplied by the difference between the Warrant Price and the “Fair Market Value” (as defined below) by (y) the Fair Market Value. Solely for purposes of
this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of
exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In
connection with the “cashless exercise” of a Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that
(i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such exercise
shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act (or any successor rule)) of the Company and, accordingly, shall not be required
to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company shall continue to be obligated to comply with its registration
obligations under the first three sentences of this subsection 7.4.1. 
 7.4.2. Cashless Exercise at
Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under
Section 18(b)(1) of the Securities Act (or any successor rule), the Company may, at its option, (i) require holders of Warrants who exercise Warrants to exercise such Warrants on a “cashless basis” in accordance with
Section 3(a)(9) of the Securities Act (or any successor rule) as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a
registration statement for the registration, under the Securities Act, of the Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary and (y) use its best efforts to register or qualify
for sale the Common Stock issuable upon exercise of the Warrant under the blue sky laws of the state of residence of the exercising Warrant holder to the extent an exemption is not available. 

 

	8.	 Concerning the Warrant Agent and Other Matters. 

8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the
Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock. 

8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1. Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and
be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If 

  
 13 

 
the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the
holder of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor
Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing, and having its
principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor
Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if
for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such
predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such
successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations. 
 8.2.2. Notice of Successor Warrant
Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date of any such appointment. 

8.2.3. Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be
consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act. 

8.3 Fees and Expenses of Warrant Agent. 

8.3.1. Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 

8.3.2. Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 

  
 14 

 8.4 Liability of Warrant Agent. 

8.4.1. Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) shall be
deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, Secretary, or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent shall rely upon
such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 
 8.4.2. Indemnity.
The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and
reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct, or bad faith. 

8.4.3. Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the
validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall
not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts
that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or
as to whether any shares of Common Stock shall, when issued, be valid and fully paid and non-assessable. 

8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same,
including countersigning physical certificates, if applicable, upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to
the Company, all monies received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of the Warrants. 
 8.6
Waiver. The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined
in that certain Investment Management Trust Agreement, dated as of March 29, 2017, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment, or satisfaction for any
Claim against the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account. 

 

	9.	 Miscellaneous Provisions.

Certificate 
 This Warrant Certificate certifies that             , or
registered assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value
(“Common Stock”), of Kayne Anderson Acquisition Corp., a Delaware corporation (the “Company”). Each whole Warrant entitles the holder, upon exercise during the period set forth in the Warrant
Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise
Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this
Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but

 A-1 

 Each whole Warrant is initially exercisable for one fully paid and
non-assessable share of Common Stock. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a

subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 
 The initial Exercise Price per share of Common Stock for
any Warrant is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by
the end of such Exercise Period, such Warrants shall become void. 
 Reference is hereby made to the further provisions of this Warrant Certificate set
forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place. 
 This Warrant
Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 
 This Warrant Certificate shall
be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

 The Warrants evidenced by this
Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of November 9, 2018 (the
“Warrant Agreement”), duly executed and delivered by the Company to American Stock Transfer & Trust Company, LLC, a New York limited liability trust company, as warrant agent (the “Warrant
Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of
the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder) of the Warrants. A copy of the Warrant Agreement may be
obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant
Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or
through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised
shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her, or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a
registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of Common Stock is current, except through “cashless
exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides that upon the occurrence of certain events the number of shares
of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a
share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the holder of the Warrant. 

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal
representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant
Certificates of like tenor evidencing in the aggregate a like number of Warrants. 

  
 A-3 

 Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant
Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided
in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 
 The Company and the Warrant
Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of
any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder
hereof to any rights of a stockholder of the Company.
