separate written contractual piggyback 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 Holder(s) 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 (including any Affiliates of such Holders) owns at such time) that can be sold without exceeding the Maximum Number of
Securities; provided, that, for the avoidance of doubt, if the Demanding Holder is an Apache Holder in connection with a Permitted Apache Offering, the Apache Holders shall not be subject to reduction pursuant to this subsection 2.2.3; (ii)
second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Class A 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 foregoing clauses (i) and (ii), the Class A Common Stock or other equity securities of other Persons
that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such Persons and that can be sold without exceeding the Maximum Number of Securities.

 2.2.4 Demand Registration Withdrawal. A Demanding Holder or a Requesting Holder shall
have the right to withdraw all or any portion of its Registrable Securities included in a Demand Registration for any or no reason whatsoever upon written notification to the Company of its intention to so withdraw at any time prior to the
effectiveness of the applicable Registration Statement; provided, however, that upon withdrawal by (i) any Demanding Holder of an amount of its Registrable Securities from the Demand Registration such that the remaining amount of Registrable
Securities of the Demanding Holder(s) and their respective Affiliates to be included in the Demand Registration is reasonably likely to result in gross sale proceeds below the Minimum Amount or (ii) the Majority-in-Interest of the Demanding Holders initiating a Demand Registration, the Company shall (with respect to clause (ii)), and shall have the right, but not the obligation (with respect to
clause (i)), to cease all efforts to secure effectiveness of the applicable Registration. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a
Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.2.4. 
 2.3
Piggyback Registration. 
 2.3.1 Piggyback Rights. 

(a) If at any time the Company proposes to file a Registration Statement under the Securities Act with respect to an 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 stockholders of the Company
including, without limitation, pursuant to subsection 2.2.1), other than a Registration Statement (i) filed pursuant to Section 2.1 hereof, (ii) with respect to the Principal Holders, filed in connection
with a Permitted Apache Offering (which shall be deemed to include the Existing Registration Statement), (iii) filed in connection with any employee stock option or other benefit plan, (iv) for an exchange offer or offering of securities solely
to the Company’s existing stockholders, (v) for an offering of debt that is convertible into equity securities of the Company, (vi) for a dividend reinvestment plan, or (vii) on Form S-4,
then the Company shall within ten (10) days (or if the Registration Statement will be a Shelf Registration Statement, within five (5) days) of the anticipated filing date of such Registration Statement give written notice of such proposed
filing to all of the Holders of Registrable Securities (the “Piggyback Registration Notice”), which notice shall (A) describe the amount and type of securities to be included in such Registration and the intended
method(s) of distribution and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt
of such written notice (such Registration a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and to permit the sale or other
disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. 

  
 13 












 (b) If at any time the Company proposes to conduct an Underwritten Offering (including an
Underwritten Offering pursuant to a Demand Registration), for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company) other than, with respect to the Principal Holders only, a
Permitted Apache Offering, then the Company shall promptly notify all Holders of such proposal reasonably in advance (and in any event at least two (2) business days before in connection with a “bought deal” or Overnight Underwritten
Offering) of the commencement of the offering, which notice shall set forth the principal terms and conditions of the issuance, including the proposed offering price (or range of offering prices), the anticipated filing date of the related
registration statement (if applicable) and the number of shares of Class A Common Stock that are proposed to be registered (the “Underwritten Offering Piggyback Notice”). Receipt of any Underwritten Offering Piggyback
Notice required to be provided in this subsection 2.3.1(b) to Holders shall be kept confidential by the Holder until such proposed Underwritten Offering is (i) publicly announced or (ii) such Holder receives notice that such
proposed Underwritten Offering has been abandoned, which such notice shall be provided promptly by the Company to each Holder. The Underwritten Offering Piggyback Notice shall offer Holders the opportunity to include in such Underwritten Offering
(and any related registration, if applicable) the number of Registrable Securities as they may request in writing (an “Underwritten Piggyback Offering”); provided, however, that in the event that the Company proposes to
effectuate the subject Underwritten Offering pursuant to an effective Shelf Registration Statement of the Company other than an Automatic Shelf Registration Statement, only Registrable Securities of Holders which are subject to an effective Shelf
Registration Statement may be included in such Underwritten Piggyback Offering, unless the Company is then able to file an Automatic Shelf Registration Statement and in the reasonable judgment of the Company, the filing of the same including
Registrable Securities of Holders that are not otherwise included in an effective Shelf Registration Statement would not have a material adverse effect on the price, timing or distribution of the Class A Common Stock in such Underwritten
Piggyback Offering. The Company shall use commercially reasonable efforts to include in each such Underwritten Piggyback Offering such Registrable Securities for which the Company has received written requests for inclusion therein
(“Underwritten Offering Piggyback Request”) within three (3) business days after sending the Underwritten Offering Piggyback Notice (or one (1) business day in connection with a “bought deal” or Overnight
Underwritten Offering). All Holders requesting to include their Registrable Securities in an Underwritten Piggyback Offering under this subsection 2.3.1(b) shall enter into an underwriting agreement in customary form with
the Underwriter(s) selected for such Underwritten Offering by the Company. 
 2.3.2 Reduction of Underwritten Piggyback Offering. If
the managing Underwriter or Underwriters in an Underwritten Piggyback Offering, in good faith, advises the Company and the Holders of Registrable Securities participating in the Underwritten Piggyback Offering in writing that the dollar amount or
number of the Class A Common Stock that the Company desires to sell, taken together with (i) the Class A Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with
Persons other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2.2 hereof, and (iii) the Class A Common
Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggyback registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then: 

  
 14 












 (a) If the Underwritten Piggyback Offering is undertaken for the Company’s account,
the Company shall include in any such Underwritten Piggyback Offering (A) first, the Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities;
(B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to
subsection 2.3.1 hereof (pro rata based on the respective number of Registrable Securities that each Holder owns at such time (including any Affiliates of such Holder)), 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 Class A Common Stock, if any, as to which Registration has been requested
pursuant to written contractual piggyback registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities; 

(b) If the Underwritten Piggyback Offering is pursuant to a request by Persons other than the Holders of Registrable Securities, then the
Company shall include in any such Underwritten Piggyback Offering (A) first, the Class A Common Stock or other equity securities, if any, of such requesting Persons, other than the Holders of Registrable Securities, which can be sold
without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register
their Registrable Securities pursuant to subsection 2.3.1 (pro rata based on the number of Registrable Securities that each Holder owns at such time (including any Affiliates of such Holder)), which can be sold without
exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Class A Common Stock or other equity securities that the
Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the
Class A Common Stock or other equity securities for the account of other Persons that the Company is obligated to register pursuant to separate written contractual arrangements with such Persons, which can be sold without exceeding the Maximum
Number of Securities. 
 2.3.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to
withdraw all or any portion of its Registrable Securities included in a Piggyback Registration or an Underwritten Piggyback Offering, as applicable, for any or no reason whatsoever upon written notification to the Company and the Underwriter or
Underwriters (if any) of his, her or its intention to withdraw such Registrable Securities from such Piggyback Registration prior to (x) in the case of a Piggyback Registration, the effectiveness of the applicable Registration Statement or
(y) in the case of any Underwritten Piggyback Offering, prior to the pricing of such Underwritten Piggyback Offering. The Company (whether on its own good faith determination or as the result of a request for withdrawal by Persons pursuant to
separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to
the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.3.3. 

  
 15 












 2.3.4 Opt-Out Notice. Any Holder of
Registrable Securities may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Holder of Registrable Securities not receive from the Company any Piggyback
Notice; provided, however, that such Holder of Registrable Securities may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a
Holder of Registrable Securities (unless subsequently revoked), the Company shall not deliver any notice to such Holder of Registrable Securities pursuant to this Section 2.3. 

2.4 Restrictions on Registration Rights. During the period that is forty-five (45) days before the Company’s good faith
estimate of the date of an Underwritten Offering (including an Underwritten Offering pursuant to a Demand Registration), for the Company’s own account, the Company shall have the right to defer for up to forty-five (45) days any
Registration pursuant to Section 2.2, other than a Permitted Apache Offering during the Apache Priority Window; provided that the Company is actively employing in good faith commercially reasonable efforts to cause such
Company-initiated Registration to become effective and may only exercise this right once in any 12-month period. 

2.5 Lock-up Period. Notwithstanding anything to the contrary contained in this Agreement and
(i) except for a Permitted Apache Offering or as required pursuant to Section 2.1 of this Agreement and (ii) subject to Section 2.6 and Section 2.7 of this
Agreement, no Registration shall be effected (including, for the avoidance of doubt, any Underwritten Offering Piggyback Request) or permitted and no Registration Statement shall become effective, with respect to any Registrable Securities held by
any Holder, until after the expiration of the Lock-up Period; provided, however, the Apache Holders may effect a Permitted Apache Offering during the Apache Priority Window. 

2.6 I Squared Apache Priority Rights. 

2.6.1 The Apache Holders may not consummate any sale of Registrable Securities in an Underwritten Offering pursuant to
Section 2.2.2 or a Piggyback Registration during the I Squared Apache Priority Window except as set forth in this Section 2.6. 

2.6.2 The Apache Holders may pursue one (1) Apache Proposed Offering during the I Squared Apache Priority Window so long as such Apache
Proposed Offering complies with the terms and conditions set forth in this Section 2.6.
 2.6.3 If the Apache
Holders desire to make or consummate any Apache Proposed Offering during the I Squared Apache Priority Window, Apache Midstream shall provide I Squared with fifteen (15) days’ advance written notice of such Apache Proposed Offering (such
notice, the “Apache Proposed Offering Notice” and such fifteen (15)-day period, the “Apache Notice Period”). At any time during the Apache Notice
Period, I Squared may elect to consummate a sale of I Squared Priority Shares in an Underwritten Offering pursuant to Section 2.2.2 (an “I Squared Apache Priority Offering”) by providing written
notice to Apache Midstream, in which case the Apache Holders shall not pursue the Apache Proposed Offering; provided, that (i) I Squared must initiate such I Squared Apache Priority Offering within fifteen (15) days of making such
election and (ii) the Apache Holders and the Blackstone Holders shall be permitted to participate (in equal proportions and with allocations among the Apache Holders designated by Apache Midstream and with allocations among the Blackstone
Holders designated by BX Aggregator) alongside the I Squared Holders in such I Squared Apache Priority Offering 

  
 16 












 
only to the extent that it is determined that there is demand in excess of the I Squared Priority Shares that the I Squared Holders propose to sell in such I Squared Apache Priority Offering
(which determination shall be made independently and in good faith by the placement agent, sales agent or Underwriter, as applicable, for such I Squared Apache Priority Offering). In the event that the I Squared Holders consummate an I Squared
Apache Priority Offering in accordance with the immediately preceding sentence, the Apache Holders will be deemed to have not pursued an Apache Proposed Offering for purposes of Section 2.6.2. 

2.6.4 In the event that either (i) I Squared notifies Apache Midstream in writing during the Apache Notice Period that the I Squared
Holders do not intend to consummate an I Squared Apache Priority Offering or (ii) the I Squared Holders do not otherwise pursue an I Squared Apache Priority Offering during the Apache Notice Period, then within fifteen (15) days following
the earlier of the receipt by Apache Midstream of such notification in writing and the expiration of the Apache Notice Period (such fifteen (15)-day period, the “Apache Proposed Offering
Window”), the Apache Holders may execute a definitive agreement in connection with such Apache Proposed Offering subject to the other terms and provisions of this Agreement but without further limitation under this
Section 2.6. In the event that (i) the Apache Holders elect not to proceed with the Apache Proposed Offering in accordance with the immediately preceding sentence and the closing price of the Class A Common Stock
on the date of the expiration of the Apache Proposed Offering Window (or, if such date is not a trading day, the trading day immediately preceding the date of such expiration) is below the Apache Notice Price or (ii) the Company prevents the
Apache Holders from consummating the Apache Proposed Offering by exercising its rights pursuant to Section 3.5 of this Agreement to initiate a Suspension Period or Blackout Period, then, in each case, the Apache Holders
will be deemed to have not pursued an Apache Proposed Offering for purposes of Section 2.6.2. 
 2.7 I Squared
Blackstone Priority Rights. 
 2.7.1 The Blackstone Holders may not consummate any sale of Registrable Securities in an Underwritten
Offering pursuant to Section 2.2.2 or a Piggyback Registration during the I Squared Blackstone Priority Window except as set forth in this Section 2.7. 

2.7.2 The Blackstone Holders may pursue one (1) Blackstone Proposed Offering during the I Squared Blackstone Priority Window so long as
such Blackstone Proposed Offering complies with the terms and conditions set forth in this Section 2.7.
 2.7.3 If
the Blackstone Holders desire to make or consummate any Blackstone Proposed Offering during the I Squared Blackstone Priority Window, BX Aggregator shall provide I Squared with fifteen (15) days’ advance written notice of such Blackstone
Proposed Offering (such notice, the “Blackstone Proposed Offering Notice” and such fifteen (15)-day period, the “Blackstone Notice Period”). At any
time during the Blackstone Notice Period, I Squared may elect to consummate a sale of I Squared Priority Shares in an Underwritten Offering pursuant to Section 2.2.2 (an “I Squared Blackstone Priority
Offering”) by providing written notice to BX Aggregator, in which case the Blackstone Holders shall not pursue the Blackstone Proposed Offering; provided, that (i) I Squared must initiate such I Squared Blackstone Priority
Offering within fifteen (15) days of making such election and (ii) the Apache Holders and the Blackstone Holders shall be permitted to participate (in equal proportions and with allocations among the


  
 17 












 
Apache Holders designated by Apache Midstream and with allocations among the Blackstone Holders designated by BX Aggregator) alongside the I Squared Holders in such I Squared Blackstone Priority
Offering only to the extent that it is determined that there is demand in excess of the I Squared Priority Shares that the I Squared Holders propose to sell in such I Squared Blackstone Priority Offering (which determination shall be made
independently and in good faith by the placement agent, sales agent or Underwriter, as applicable, for such I Squared Blackstone Priority Offering). In the event that the I Squared Holders consummate an I Squared Blackstone Priority Offering in
accordance with the immediately preceding sentence, the Blackstone Holders will be deemed to have not pursued an Blackstone Proposed Offering for purposes of Section 2.7.2. 

2.7.4 In the event that either (i) I Squared notifies BX Aggregator in writing during the Blackstone Notice Period that the I Squared
Holders do not intend to consummate an I Squared Blackstone Priority Offering or (ii) the I Squared Holders do not otherwise pursue an I Squared Blackstone Priority Offering during the Blackstone Notice Period, then within fifteen
(15) days following the earlier of the receipt by BX Aggregator of such notification in writing and the expiration of the Blackstone Notice Period (such fifteen (15)-day period, the “Blackstone
Proposed Offering Window”), the Blackstone Holders may execute a definitive agreement in connection with such Blackstone Proposed Offering subject to the other terms and provisions of this Agreement but without further limitation under
this Section 2.7. In the event that (i) the Blackstone Holders elect not to proceed with the Blackstone Proposed Offering in accordance with the immediately preceding sentence and the closing price of the Class A
Common Stock on the date of the expiration of the Blackstone Proposed Offering Window (or, if such date is not a trading day, the trading day immediately preceding the date of such expiration) is below the Blackstone Notice Price or (ii) the
Company prevents the Blackstone Holders from consummating the Blackstone Proposed Offering by exercising its rights pursuant to Section 3.5 of this Agreement to initiate a Suspension Period or Blackout Period, then, in each
case, the Blackstone Holders will be deemed to have not pursued an Blackstone Proposed Offering for purposes of Section 2.7.2. 

2.8 Apache and Blackstone Joint Transaction. In the event that the Apache Holders and the Blackstone Holders desire to concurrently
pursue an Apache Proposed Offering and a Blackstone Proposed Offering, respectively (such concurrent offering, a “Combined Offering”), during the I Squared Apache Priority Window, the provisions of
Section 2.6 and Section 2.7 shall apply to the Apache Holders and the Blackstone Holders, respectively, and any Combined Offering that is ultimately consummated shall be allocated among the Apache
Holders and the Blackstone Holders in equal proportions.

 18

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

(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

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

 19 












 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 3.5 hereof; 
 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 the 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); 

  
 20 












 3.1.15 if the Registration involves the Registration of Registrable Securities involving
gross proceeds in excess of $75 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. 
 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 Customary Lock-Up Agreements. In connection with each Underwritten Offering pursuant
to Section 2.2.2, each Holder, other than the Apache Holders in connection with any Permitted Apache Offering, who at the time of such Underwritten Offering holds, together with its Affiliates, at least 10% of the
then-outstanding Common Stock, agrees, if requested, to become bound by and to execute and deliver a customary lock-up agreement restricting such Holder’s right to (i) Transfer any equity securities
of the Company held by such Holder or (ii) enter into any swap or other arrangement that Transfers to another any of the economic consequences of ownership of such securities during the period commencing on the date of the final Prospectus
relating to such Registration and ending on the date sixty (60) days thereafter; provided that no Holder shall be required to agree to a lock-up period longer than the
lock-up period for the Company, the Demanding Holder(s), or the directors and “executive officers” (as defined under Section 16 of the Exchange Act) of the Company. The terms of such lock-up agreements shall include customary carve-outs from the restrictions on Transfer set forth therein and each Holder’s lock-up agreement shall require equal
treatment of all Holders in the event of any early release from the lock-up. The Company shall, if requested by the
Majority-in-Interest of the Holders participating in such Registration, cause its directors and executive officers to agree to become bound by and to execute and deliver
a similar lock-up agreement. 
 3.5 Suspension of Sales; Adverse Disclosure. 

3.5.1 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”). 

  
 21 












 3.5.2 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 (i) require the Company to make an Adverse Disclosure or (ii) 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 sixty (60) 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. 
 3.5.3 The Company shall immediately
notify the Holders of the expiration of any period during which it exercised its rights under Section 2.4 or this Section 3.5. Notwithstanding anything to the contrary in this
Section 3.5, in no event shall any period during which the Company exercised its rights under Section 2.4, Blackout Periods and any Suspension Periods continue for more than sixty (60) days in
the aggregate during any 180-day period or more than one hundred twenty (120) days in the aggregate during any 365-day period. 

3.6 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 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. 

  
 22 












 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. 
 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. 

  
 23 












 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 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.

or in part. 
 5.2.2 No Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in

“Adoption Agreement”) to be bound by this Agreement in the form of Exhibit A hereto and shall thenceforth be a “Holder.” 

5.2.3 This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors

5.3 Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF counterparts), each of which

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

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, the
Apache Holders, the Blackstone Holders the I Squared Holders or the Management Holders, as applicable, solely in their respective capacity as Existing Holdings, Apache Holders, Blackstone Holders, I Squared Holders, or Management Holders, as
applicable, in a manner that is materially different from the other Holders, shall require the consent of the Existing Holders, the Apache Holders, the Blackstone Holders, the I Squared Holders or the Management 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 Preferred Registration Rights Agreement, 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. Further, the Company shall not, prior to the termination of this Agreement, grant any
registration rights that are superior to, or in any way subordinate, the rights granted to the Holders hereby, including any registration or other right that is directly or indirectly intended to violate or subordinate the rights granted to the

obligations hereunder, on such date on which such Holder, together with such Holder’s Affiliates, no longer owns any Registrable Securities. The provisions of Section 3.6 and Article IV shall
survive any termination. 

  
 26 












 5.8 Holder Action. Whenever the Existing Holders, Principal Holders, Apache Holders,
Blackstone Holders, I Squared Holders or Management Holders are entitled to act or refrain from acting, the Existing Holders, Principal Holders, Apache Holders, Blackstone Holders, I Squared Holders or Management Holders, as applicable, shall do so
by the determination of the Majority-in-Interest of the Existing Holders, Principal Holders, Apache Holders, Blackstone Holders, I Squared Holders or Management Holders,
as applicable.
