Holders of Registrable Securities having an aggregate Market Value of at least One Hundred Million dollars ($100,000,000) may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe

Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting
Holder”) shall so notify the Corporation, in writing, within five (5) days after the receipt by the Holder of the notice from the Corporation. Upon receipt by the Corporation of any such written notification from a Requesting

Registration. Notwithstanding the forgoing, the Holders may make no more than two (2) Demand Registrations in any 365-day period and no more than four (4) Demand Registrations during the term of this

 2.1.2 Underwritten Offering. Subject to the provisions of
Section 2.1.5 and Section 2.1.6 hereof, if a majority-in-interest of the Demanding Holders so advise the Corporation
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 Section 2.1.2 shall enter into an underwriting agreement in customary form with the
Underwriter(s) selected for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration, which Underwriter(s) must
be reasonably satisfactory to the Corporation. If the Demanding Holders are not able to obtain the commitment of an Underwriter to firmly underwrite the Underwritten Offering pursuant to this Section 2.1.2, such Demanding
Holders shall withdraw the Demand Registration in accordance with Section 2.1.6 or convert such Demand Registration into a Demand Registration not involving an Underwriter in accordance with
Section 2.1.1. 
 2.1.3 Shelf Registration. The Corporation shall file a Registration Statement (the
“Shelf 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 Section 2.1.3 and shall use its commercially reasonable best efforts to cause such Registration Statement to be
declared effective no later than the seventh (7th) anniversary of the funding and closing of the Preferred Offering (the “Registration Deadline”); provided, that the
Corporation shall not be obligated to file such Shelf Registration Statement earlier than the sixth (6th) anniversary of the funding and closing of the Preferred Offering. Notwithstanding the
foregoing, if prior to the Registration Deadline, the Corporation takes any of the actions described in the definition of Series A Restricted Action in the Partnership Agreement, the Corporation shall file such Shelf Registration Statement no later
than the thirtieth (30th) day following the first Optional Exchange (as defined in the Partnership Agreement) following such Series A Restricted Action (the “Restricted Action
Registration Deadline”) and shall use its commercially reasonable best efforts to cause such Shelf Registration Statement to be declared effective as soon thereafter as commercially reasonably practicable. The Registration Statement
filed with the Commission pursuant to this Section 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 Corporation, 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 Corporation 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 Corporation 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 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

  
 6 

 
equivalent or successor form, and shall contain a Prospectus in such form as to permit any 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 Section 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 Corporation shall use its commercially reasonable best efforts to cause a Registration Statement filed pursuant to this
Section 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 (the
“Effectiveness Period”). As soon as practicable following the effective date of a Registration Statement filed pursuant to this Section 2.1.3, but in any event within three (3) Business Days of
such date, the Corporation shall notify the Holders of the effectiveness of such Registration Statement. When effective, a Registration Statement filed pursuant to this Section 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).

Registration Statement required by Section 2.1.3 does not become or is not declared effective by the Registration Deadline or is not filed by the Restricted Action Registration Deadline, if applicable, or (iv) the
Shelf Registration Statement is declared effective but (A) the Shelf Registration Statement shall thereafter be withdrawn by the Corporation or shall become subject to an effective stop order issued pursuant to Section 8(d) of the
Securities Act suspending the effectiveness of such Shelf Registration Statement (except as specifically permitted pursuant to Section 3.4) without being succeeded by an additional Shelf Registration Statement filed and
declared effective within fifteen (15) Business Days, (B) the use of any Prospectus that is a part of the Shelf Registration Statement is suspended pursuant to Section 3.4 in excess of the number of days permitted
thereby or (C) except as addressed by the foregoing clauses (A) and (B) or except as expressly permitted by Section 3.4, the Shelf Registration Statement fails to be available for the resale by the
Holders of all the Registrable Securities required to be included therein during the Effectiveness Period (each such event referred to in clauses (i), (ii), (iii), and (iv), a “Registration
Default”), then each Holder shall be entitled to a payment (with respect to each of the Holders’ pro rata share of Registrable Securities as liquidated damages and not as a penalty), (x) for the first ninety (90) days
following the occurrence of such Registration Default, an amount equal to 0.25% of the aggregate Market Value of the then-outstanding Registrable Securities on the ninetieth (90th) day of such
period (the “Liquidated Damages Multiplier”), which shall accrue daily, and (y) for each non-overlapping 90-day period beginning on the
ninety first (91st) day thereafter, an amount equal to the amount set forth in clause (x) plus an additional 0.25% of the Liquidated Damages Multiplier for each subsequent ninety
(90) days (i.e., 0.50% for 91-180 days, 0.75% for 181-270 days, 

  
 7 

 
1.00% for 271-360 days, etc.), which shall accrue daily, up to a maximum amount equal to 2.50% of the Liquidated Damages Multiplier per non-overlapping 90-day period (the “Liquidated Damages”), until such time as such Registration Default is cured or there are no longer any Registrable
Securities outstanding. The Liquidated Damages shall be payable within fifteen (15) Business Days after the end of each such 90-day period in immediately available funds to the account or accounts
specified by the applicable Holders. Any amount of Liquidated Damages shall be prorated for any period of less than ninety (90) days accruing during any period for which a Holder is entitled to Liquidated Damages hereunder. The Corporation may
request a waiver of all or any portion of the Liquidated Damages, which may be granted by the consent of the Holders of at least sixty-seven percent (67%) of the then-outstanding number of Registrable Securities, in their sole discretion, and which
such waiver shall apply to all the Holders of Registrable Securities. 
 2.1.5 Reduction of Underwritten Offering. If the managing
Underwriter or Underwriters in an Underwritten Offering pursuant to a Demand Registration, in good faith, advises the Corporation, 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 Class A Common Stock or other equity securities that the Corporation desires to sell, and the Class A 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 Corporation 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;

used by the Corporation 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 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 Corporation 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 Corporation 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 Corporation 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; 

  
 12 

 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; 
 3.1.10 permit a representative of the Holders (such
representative to be selected by a majority-in-interest 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 Corporation’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 Corporation, prior to the release or disclosure of any such information; 
 3.1.11 obtain a “cold comfort” letter from the
Corporation’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 Corporation 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 Corporation, 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 Corporation’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); 

  
 13 

 3.1.15 if the Registration involves the Registration of Registrable Securities involving
gross proceeds in excess of Fifty Million dollars ($50,000,000), cause the senior executive officers of the Corporation to participate in customary “road show” presentations that may be reasonably requested by the managing Underwriter or
Underwriters in any 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 Corporation. 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 Corporation unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Corporation 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 Corporation 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 Corporation 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 Corporation 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 Corporation to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Corporation for
reasons beyond the Corporation’s control, then the Corporation 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 Corporation to be necessary for such purpose (any such period, a “Blackout
Period”); provided, that back-to-back delays or suspensions pursuant to this Section 3.4.2 are not permitted. In the event
the Corporation 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. 

  
 14 

 3.4.3 The Corporation 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 sixty (60) days in the aggregate during any 180-day period or 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 Corporation, 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 Corporation 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 Corporation’s filing of such reports on the Commission’s EDGAR
system). The Corporation 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 Class A 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 Corporation 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 Corporation 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 Corporation by such Holder expressly for use therein. The Corporation 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 Corporation in writing such information and affidavits as the Corporation reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify

  
 15 

 
the Corporation, its directors and officers and agents, and each Person who controls the Corporation (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 Corporation. 

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 Corporation 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 Corporation’s or such Holder’s indemnification is unavailable for any reason. 

  
 16 

 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
Section 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 Sections 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 Section 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 Section 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 Section 4.1.5 from any Person who was not guilty of such fraudulent misrepresentation. 

ARTICLE V

notices, on the third (3rd) Business Day following the date on which it is mailed and, in the case of notices delivered by courier service, hand delivery, electronic mail, telecopy, telegram or
facsimile, at such time as it is delivered to the addressee (with the delivery receipt or the affidavit of messenger) or at such time as delivery is refused by the addressee upon presentation. Any notice or communication under this Agreement must be

 17 

 5.2 Assignment; No Third Party Beneficiaries. 

5.2.1 This Agreement and the rights, duties and obligations of the Corporation hereunder may not be assigned or delegated by the Corporation
in whole 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 part, except in connection with a Transfer of Registrable Securities by such Holder to a Permitted Transferee. 
 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 Corporation 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 Corporation unless and until the Corporation 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. (I) THIS AGREEMENT HAS BEEN EXECUTED AND DELIVERED AND SHALL BE CONSTRUED, INTERPRETED AND GOVERNED PURSUANT TO THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO ANY CONFLICT OF LAWS PRINCIPLES WHICH, IF APPLIED,
MIGHT PERMIT OR REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THE AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN THE STATE OF DELAWARE. 

5.5 Amendments and Modifications. Upon the written consent of the Corporation and the Holders of at least sixty-seven percent (67%) of
the outstanding number of 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, 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 Corporation, in a manner
that is materially different from the other Holders (in such capacity) shall require the consent of the 

  
 18 

 
Holder so affected. No course of dealing between any Holder or the Corporation and any other party hereto or any failure or delay on the part of a Holder or the Corporation in exercising any
rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Corporation. 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 Existing Registration Rights Agreement, the Corporation represents and warrants that it has not granted, and is not subject to, any registration rights that are superior to, or that in any way subordinate, the
rights granted to the Holders hereby. The Corporation 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 Holders hereby. 

5.7 Term. The provisions of this Agreement shall terminate with respect to any Holder and be of no further force or effect
when all Registrable Securities held by such Holder no longer constitute Registrable Securities; provided, that the provisions of Article IV shall survive for any sales of Registrable Securities prior to such date.

 5.8 Holder Action. Whenever the Holders are entitled to act or refrain from acting, the Holders shall do so by the determination of
a majority-in-interest of the then-outstanding number of Registrable Securities held by the Holders.

connection with any Stock Option Plan, a stock option granted over shares of Class A Common Stock to a Partnership Employee is duly exercised, solely for U.S. federal (and applicable state and local) income tax purposes, the following
transactions shall be deemed to have occurred: 
 (i) The Corporation shall sell to the Optionee, and the Optionee shall purchase from the
Corporation, the number of shares of Class A Common Stock equal to the number of shares of Class A Common Stock as to which such stock option is being exercised multiplied by the following: (A) the exercise price payable by the
Optionee in connection with the exercise of such stock option divided by (B) the Value of a share of Class A Common Stock at the time of such exercise. 

(ii) The Corporation shall sell to the Partnership (or, if the Optionee is an employee of, or other service provider to, a Subsidiary, the
Corporation shall sell to such Subsidiary), and the Partnership (or such Subsidiary, as applicable) shall purchase from the Corporation, a number of shares of Class A Common Stock equal to the excess of (x) the number of shares of
Class A Common Stock as to which such stock option is being exercised over (y) the number of shares of Class A Common Stock sold pursuant to Section 3.10(b)(i) hereof. The purchase price per share of
Class A Common Stock for such sale of shares of Class A Common Stock to the Partnership (or such Subsidiary) shall be the Value of a share of Class A Common Stock as of the date of exercise of such stock option. 

(iii) The Partnership shall transfer to the Optionee (or, if the Optionee is an employee of, or other service provider to, a Subsidiary, the
Subsidiary shall transfer to the Optionee) at no additional cost to such Partnership Employee and as additional compensation to such Partnership Employee, the number of shares of Class A Common Stock described in
Section 3.10(b)(ii). 
 (iv) The Corporation shall be deemed to have contributed any amounts received by the
Corporation pursuant to Section 3.10(b)(i) and any amount deemed to be received by the Partnership pursuant to Section 3.10(b)(ii) in connection with the exercise of such stock option. 

The transactions described in this Section 3.10(b) are intended to comply with the provisions of Treasury Regulations
Section 1.1032-3 and shall be interpreted consistently therewith. 
 (c) Restricted Stock Granted to Partnership Employees. If
at any time or from time to time, in connection with any Equity Plan (other than a Stock Option Plan), any shares of Class A Common Stock are issued to a Partnership Employee (including any shares of Class A Common Stock that are subject
to forfeiture in the event such Partnership Employee terminates his or her employment with the Partnership or any Subsidiary) in consideration for services performed for the Partnership or any Subsidiary, on the date (such date, the
“Vesting Date”) that the Value of such shares is includible in taxable income of such Partnership Employee, the following events will be deemed to have occurred solely for U.S. federal (and applicable state and local) income
tax purposes: (i) the Corporation shall be deemed to have sold such shares of Class A Common Stock 

  
 31 

 
to the Partnership (or, if such Partnership Employee is an employee of, or other service provider to, a Subsidiary, to such Subsidiary) for a purchase price equal to the Value of such shares of
Class A Common Stock, (ii) the Partnership (or such Subsidiary) shall be deemed to have delivered such shares of Class A Common Stock to such Partnership Employee, (iii) the Corporation shall be deemed to have contributed the
purchase price for such shares of Class A Common Stock to the Partnership as a Capital Contribution and (iv) in the case where such Partnership Employee is an employee of a Subsidiary, the Partnership shall be deemed to have contributed
such amount to the capital of the Subsidiary. 
 (d) Future Stock Incentive Plans. The Partners acknowledge and agree that, in the
event that the Corporation adopts, modifies or terminates any stock incentive plans for the benefit of employees, directors or other business associates of the Corporation, the Partnership or any of their respective Affiliates, amendments to this
Section 3.10 may become necessary or advisable and, subject to Section 6.01(e)(i), any approval or consent to any such amendments requested by the Corporation shall be deemed granted by the General
Partner and the Series A Preferred Unitholders without the requirement of any further consent or acknowledgement of any other Partner. 

(e) Anti-dilution adjustments. For all purposes of this Section 3.10, the number of shares of Class A
Common Stock and the corresponding number of Common Units shall be determined after giving effect to all anti-dilution or similar adjustments that are applicable, as of the date of exercise or vesting, to the option, warrant, restricted stock or
other equity interest that is being exercised or becomes vested under the applicable Stock Option Plan or other Equity Plan and applicable award or grant documentation. 

Section 3.11 Dividend Reinvestment Plan, Cash Option Purchase Plan, Stock Incentive Plan or Other Plan.
Except as may otherwise be provided in this Article III, all amounts received or deemed received by the Corporation in respect of any dividend reinvestment plan, cash option purchase plan, stock incentive or other stock or subscription plan
or agreement, either (a) shall be utilized by the Corporation to effect open market purchases of shares of Class A Common Stock or (b) if the Corporation elects instead to issue new shares of Class A Common Stock with respect to
such amounts, shall be contributed by the Corporation to the Partnership in exchange for additional Common Units. Upon such contribution, the Partnership will issue to the Corporation a number of Common Units equal to the number of new shares of
Class A Common Stock so issued. 
 Section 3.12 Establishment of Series A Preferred Units. 

(a) General. There is hereby created a class of Units designated as “Series A Cumulative Redeemable Preferred Units” (such
Units, together with any Series A PIK Units, the “Series A Preferred Units”), with the designations, preferences and relative, participating, optional or other special rights, powers and
duties as set forth in this Section 3.12 and elsewhere in this Agreement. 

  
 32 

 (b) Issuance of the Series A Preferred Units. A total of 625,000 Series A Preferred
Units (other than Series A PIK Units) were issued by the Partnership to the Purchasers on the Series A Issue Date pursuant to the terms and conditions of the Series A Preferred Unit Purchase Agreement and, as set forth in
Section 3.01(a), the Purchasers were, at the Effective Time and concurrently with the Series A Preferred Unit Purchase, admitted to the Partnership as Limited Partners and deemed Series A Preferred Unitholders, and the
Partnership may only issue additional Series A Preferred Units in the form of Series A PIK Units in accordance with Section 4.01(b)(ii) or as otherwise permitted by Section 6.01(e)(iii).
Concurrently with such issuance, the Series A Preferred Unitholders have entered into the Series A Registration Rights Agreement with the Corporation. Each Series A Preferred Unit shall constitute a “security” within the meaning of, and
governed by, (i) Article 8 of the Uniform Commercial Code (including Section 8-102(a)(15) thereof) as in effect from time to time in the State of Delaware, and (ii) the corresponding provisions
of the Uniform Commercial Code of any other applicable jurisdiction that now or hereafter substantially includes the 1994 revisions to Article 8 thereof as adopted by the American Law Institute and the National Conference of Commissioners on Uniform
State Laws and approved by the American Bar Association on February 14, 1995. 
 ARTICLE IV 

DISTRIBUTIONS 

Section 4.01 Distributions. 

(a) Available Cash; Other Distributions. To the extent permitted by applicable Law and hereunder, Distributions to Limited Partners may
be declared by the General Partner out of Available Cash or other funds or property legally available therefor in such amounts and on such terms (including the payment dates of such Distributions) as the General Partner shall determine;
provided, however, that the General Partner shall have the obligation to make Distributions as set forth in Section 4.01(b), Section 4.01(d) and
Section 14.02; provided, further, that, notwithstanding any other provision herein to the contrary, no Distributions shall be made to any Limited Partner to the extent such Distribution would violate Section 15-309 of the Delaware Act. The General Partner shall designate a Record Date for all Distributions and shall give notice to each Unitholder entitled to receive such Distribution of the Record Date, the
amount and the terms of the Distribution and the payment date thereof. In furtherance of the foregoing, it is intended that the General Partner shall, to the extent permitted by applicable Law and elsewhere in this Agreement, and after giving effect
to Section 4.01(b), have the right in its sole discretion to make Distributions to the Limited Partners pursuant to this Section 4.01(a) in such amounts as shall enable the Corporation to pay
dividends or to meet its obligations (to the extent such obligations are not otherwise able to be satisfied as a result of the Distributions required to be made pursuant to Section 4.01(d) or reimbursements required to be
made pursuant to Section 6.05). 
 (b) Distributions on the Series A Preferred Units. After making any
Distributions and Tax Advances required to paid pursuant to Section 4.01(d): 
 (i) Subject to
Section 4.01(b)(ii), commencing with the Quarter ending on June 30, 2019, the Series A Preferred Unitholders as of the applicable Record Date for each Quarter shall be entitled to receive, in respect of each
outstanding Series A Preferred Unit, cumulative distributions in respect of such Quarter equal to the sum of (A) the Series A Distribution Amount for such Quarter, which Series A Distribution Amount shall accumulate from day to day, whether or
not declared, and (B) any Series A Unpaid Distributions (collectively, a “Series A Quarterly Distribution”). With respect to any Quarter (or portion thereof for which a Series A Quarterly

  
 33 

 
Distribution is due) ending on or prior to December 31, 2020 (the “Series A Initial Distribution Period”), such Series A Quarterly Distribution in respect of each
Series A Preferred Unit may be paid, as determined by the General Partner in its sole discretion, in Series A PIK Units, in cash or in a combination of Series A PIK Units and cash. Any such Series A PIK Unit issued in respect of a Series A Preferred
Unit shall not be treated as separate, and shall be treated as indivisible from, such Series A Preferred Unit for purposes of all Transfers, exchanges, redemptions, repurchases and acquisitions of Series A Preferred Units hereunder, and any such
Transfers, exchanges, redemptions, repurchases and acquisitions of Series A PIK Units shall be pro rata among such Series A PIK Units and the Series A Preferred Units to which such Series A PIK Units relate. For any Quarter ending after the
Series A Initial Distribution Period, all Series A Quarterly Distributions in respect of each Series A Preferred Unit shall be paid in cash. If, during the Series A Initial Distribution Period, the General Partner elects to pay all or a portion of a
Series A Quarterly Distribution in respect of a Series A Preferred Unit in Series A PIK Units, the General Partner shall provide notice thereof to the Series A Preferred Unitholders at least ten (10) days prior to the Series A Distribution
Payment Date therefor and the number of Series A PIK Units to be issued in connection with such Series A Quarterly Distribution shall equal the quotient of (x) the Series A Distribution Amount payable in respect of such Series A Quarterly
Distribution to be paid in Series A PIK Units, divided by (y) the Series A Issue Price; provided, that, with respect to each Quarter with respect to which the Partnership elects (or is deemed to have elected) to pay any Series A
Quarterly Distributions in the form of Series A PIK Units, such Series A PIK Units will be allocated pro rata among the Series A Preferred Unitholders in accordance with their respective Series A Preferred Unit Percentage Interests. Each
Series A Quarterly Distribution shall be due and payable quarterly no later than the forty-fifth (45th) day following the end of the applicable Quarter (each such payment date, a
“Series A Distribution Payment Date”). Notwithstanding the foregoing, the Series A Distribution Amount for the Quarter in which the Series A Issue Date occurs shall be prorated for such period, commencing on the Series A
Issue Date and ending on, and including the last day of such Quarter. 
 (ii) When any Series A PIK Units are payable to a Series A
Preferred Unitholder pursuant to this Section 4.01(b), the Partnership shall issue the Series A PIK Units to such holder in accordance with Section 4.01(b)(i) on the applicable Series A
Distribution Payment Date (the date of issuance of such Series A PIK Units, the “Series A PIK Payment Date”). On the Series A PIK Payment Date, the Partnership shall issue such Series A PIK Units by making a notation in
book-entry form in the books of the Partnership, and all such Series A PIK Units shall, when so issued, be duly authorized, validly issued, fully paid and non-assessable Limited Partner Interests, except as
such non-assessability may be affected by Sections 17-303, 17-607 or 17-804 of the
Delaware Act, and shall be free from preemptive rights and free of any lien, claim, rights or encumbrances, other than those arising under the Delaware Act or this Agreement. 

(iii) The aggregate Series A Distribution Amount (excluding any portion paid in kind) to be so distributed in respect of the Series A
Preferred Units outstanding as of the Record Date for a Series A Quarterly Distribution shall be paid out of Available Cash with respect to the applicable Quarter prior to making any other distribution (whether of Available Cash or other property).
To the extent that any portion of a Series A Quarterly Distribution to be paid in cash with respect to any Quarter exceeds the amount of Available Cash for such Quarter, an amount of cash equal to the Available Cash for such Quarter will be paid to
the Series A Preferred Unitholders pro rata in accordance with their Series A Preferred Unit Percentage Interests and the balance of such Series A Quarterly Distribution shall be deemed unpaid. 

  
 34 

 (iv) In the event of Series A Unpaid Distributions, then from and after the first date of
the occurrence of such Series A Unpaid Distributions and continuing until such Series A Unpaid Distributions are cured by payment in full in cash of all such arrearages, such Series A Unpaid Distributions, unless and until paid, will accrue and
accumulate from and including the first day of the Quarter immediately following the Quarter in respect of which the first such payment is due until all such Series A Unpaid Distributions are paid in full in cash. 

(v) Until such time as all Series A Unpaid Distributions are paid in full in cash or if, for any Quarter, the Partnership has paid a Series A
Quarterly Distribution in whole or in part in Series A PIK Units for such Quarter or has failed to make any Tax Advances for such Quarter in accordance with Section 4.01(d), the Partnership shall not be permitted to, and
shall not, declare or make, any cash Distributions, redemptions or repurchases in respect of any Series A Junior Securities or Series A Parity Securities (including, for the avoidance of doubt, with respect to the Quarter for which the Partnership
first failed to pay in full in cash the Series A Distribution Amount of any Series A Quarterly Distribution when due or first paid a Series A Quarterly Distribution in whole or in part in Series A PIK Units, as applicable); provided,
that, the Partnership may at any time pay Distributions on Series A Junior Securities to the extent such Distribution is payable solely in Series A Junior Securities. 

(c) Common Distributions. Subject to Section 6.01(e), and only to the extent permitted by
Section 4.01(b)(v), Distributions may be made to the Common Unitholders as of the close of business on the applicable Record Date on a pro rata basis in accordance with each Common Unitholder’s Common Unit
Percentage Interest as of the close of business on such Record Date. 
 (d) Tax Distributions and Tax Advances. With respect to any
Taxable Year (or portion thereof) ending after the date hereof: 
 (i) The Partnership shall make Distributions to all Common Unitholders
pro rata, in accordance with each Common Unitholder’s Common Unit Percentage Interest, on a quarterly basis and in such amounts as necessary to enable the Corporation to timely satisfy all of its U.S. federal, state and local and non-U.S. tax liabilities. 
 (ii) If a Partner (other than the Corporation) has an Assumed Tax Liability
at a Tax Advance Date in excess of the sum of the cumulative amount of cash distributed under Sections 4.01(a), 4.01(b), 4.01(c) and 4.01(d)(i), any guaranteed payments made hereunder, and any Tax Advances (as defined
below), without duplication, remitted to such Partner through such date, the Partnership shall, to the extent permitted by applicable Law, and subject to the availability of funds and any restrictions contained in any agreement to which the
Partnership or any of its Subsidiaries is bound, make advances to such Partner in an amount equal to such excess (a “Tax Advance”). Any such Tax Advance shall be treated as an advance against and, thus, shall reduce (without
duplication), any future distributions that would otherwise be made to such Partner pursuant to Sections 4.01(a), 4.01(b), 4.01(c), 4.01(d)(i) and 14.02(c), and any guaranteed payments made hereunder, without
duplication. Notwithstanding the foregoing, such Partner may choose to decline any Tax Advance payable to such Partner pursuant to this Section 4.01(d)(ii). If 

  
 35 

 
there is a Tax Advance outstanding with respect to a Partner who (A) participates in a Common Redemption (including, for the avoidance of doubt, any Direct Exchange at the option of the
Corporation pursuant to Section 11.03) or (B) Transfers Common Units pursuant to the provisions of Article X, then in each case such Partner shall indemnify and hold harmless the Partnership against such Tax
Advance, and shall be required to promptly pay to the Partnership (but in all events within fifteen (15) days after the date of the applicable Common Redemption or Transfer, as the case may be) an amount of cash equal to the proportionate share
of such Tax Advance relating to its Common Units subject to the Common Redemption or Transfer (determined at the time of such Common Redemption or Transfer based on the number of Units subject to such Common Redemption or Transfer as compared to the
total number of Common Units held by such Partner); provided, that, in the case of a Transfer described in clause (B), such Partner shall not be required to pay such amount of cash equal to the proportionate share of such Tax
Advance relating to its Common Units subject to the Transfer, if the transferee agrees to assume the Partner’s obligation to repay to the Partnership such amount equal to the proportionate share of the Partner’s existing Tax Advance
relating to such Common Units subject to the Transfer, and such Partner shall be relieved from any liabilities associated with and the obligation to repay its existing Tax Advance relating to such Common Units subject to the Transfer. The
obligations of each Partner pursuant to the preceding sentence shall survive the withdrawal of any Partner or the transfer of any Partner’s Units in the Partnership and shall apply to any current or former Partner. For the avoidance of doubt,
any repayment of a Tax Advance pursuant to the previous sentence shall not be treated as a Capital Contribution. 
 (iii) At each Tax
Advance Date, the Partnership shall provide to each Series A Preferred Unitholder a computation of such Series A Preferred Unitholder’s Assumed Tax Liability (including in the event that such Assumed Tax Liability is zero), together with
supporting work papers or other materials providing reasonable detail with respect to such computation. 

Section 4.02 Restricted Distributions. Notwithstanding any provision to the contrary contained in this
Agreement, the Partnership shall not make any Distribution to any Partner on account of any Limited Partner Interest if such Distribution would violate any applicable Law or the terms of the Existing Credit Agreement or any other Credit Agreement or
other debt financing of the Partnership or its Subsidiaries that is, in each case, effected after the Effective Time in accordance with the terms of this Agreement, including Section 6.01(e). 

ARTICLE V 
 CAPITAL ACCOUNTS;
ALLOCATIONS; TAX MATTERS 
 Section 5.01 Capital Accounts. The Partnership shall maintain a separate
Capital Account for each Partner according to the rules of Treasury Regulations Section 1.704-1(b)(2)(iv). For this purpose, the Partnership may (in the discretion of the General Partner), upon the occurrence of the events specified in Treasury
Regulations Section 1.704-1(b)(2)(iv)(f), increase or decrease the Capital Accounts in accordance with the rules of such Treasury Regulations and Treasury Regulations Section 1.704-1(b)(2)(iv)(g) to reflect a revaluation of
Partnership property. 

  
 36 

 Section 5.02 Allocations. After giving effect to the
allocations under Section 5.03, Profits and Losses for any Taxable Year or other Fiscal Period shall be allocated among the Capital Accounts of the Partners in such a manner that, after adjusting for all Capital
Contributions and Distributions through the end of such Taxable Year or other Fiscal Period, the Capital Account balance of each Partner, immediately after making such allocation, is as nearly as possible equal to (a) the amount such Partner
would receive pursuant to Section 14.02(d) if all of the assets of the Partnership on hand at the end of such Taxable Year or other Fiscal Period were sold for cash equal to their Book Values, all liabilities of the
Partnership were satisfied in cash in accordance with their terms (limited with respect to each nonrecourse liability to the Book Value of the assets securing such liability), and all remaining or resulting cash were distributed, in accordance with
Section 14.02(d) (for this purpose, ignoring clause (a)(i) of the definition of Series A Redemption Price), to the Partners, minus (b) such Partner’s share of the Partnership Minimum Gain and Partner
Minimum Gain, computed immediately prior to the hypothetical sale of assets, and the amount any such Partner is treated as obligated to contribute to the Partnership, computed immediately after the hypothetical sale of assets. Notwithstanding any
contrary provision in this Agreement, the General Partner shall make appropriate adjustments to allocations of Profits and Losses to (or, if necessary, allocate items of gross income, gain, loss or deduction of the Partnership among) the Common
Unitholders such that, to the maximum extent possible, the Capital Accounts of the Common Unitholders are proportionate to their Common Unit Percentage Interests. In each case, such adjustments or allocations shall occur, to the maximum extent
possible, in the Taxable Year or other Fiscal Period of the event requiring such adjustments or allocations. 

Section 5.03 Regulatory and Special Allocations. 

(a) Partner nonrecourse deductions (as defined in Treasury Regulations Section 1.704-2(i)(2))
attributable to partner nonrecourse debt (as defined in Treasury Regulations Section 1.704-2(b)(4)) shall be allocated in the manner required by Treasury Regulations
Section 1.704-2(i). If there is a net decrease during a Taxable Year in Partner Minimum Gain, Profits for such Taxable Year (and, if necessary, for subsequent Taxable Years) shall be allocated to the
Partners in the amounts and of such character as determined according to Treasury Regulations Section 1.704-2(i)(4). 
 (b) Nonrecourse
deductions (as determined according to Treasury Regulations Section 1.704-2(b)(1)) for any Taxable Year shall be allocated pro rata among the Partners in accordance with each Partner’s interest in the Partnership as determined by
the General Partner in its reasonable discretion. Except as otherwise provided in Section 5.03(a), if there is a net decrease in the Partnership Minimum Gain during any Taxable Year, each Partner shall be allocated Profits
for such Taxable Year (and, if necessary, for subsequent Taxable Years) in the amounts and of such character as determined according to Treasury Regulations Section 1.704-2(f). This Section 5.03(b) is intended to be a
minimum gain chargeback provision that complies with the requirements of Treasury Regulations Section 1.704-2(f), and shall be interpreted in a manner consistent therewith. 

(c) If any Partner that unexpectedly receives an adjustment, allocation or Distribution described in Treasury Regulations Sections
1.704-1(b)(2)(ii)(d)(4), (5) and (6) has an Adjusted Capital Account Deficit as of the end of any Taxable Year, computed after the application of Sections 5.03(a) and 5.03(b) but before the
application of any other provision of this Article V, then Profits for such Taxable Year shall be allocated to such Partner in proportion to, and to the extent of, such Adjusted Capital Account Deficit. This
Section 5.03(c) is intended to be a qualified income offset provision as described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted in a manner consistent therewith. 

  
 37 

 (d) If the allocation of Losses to a Partner would create or increase an Adjusted Capital
Account Deficit, there shall be allocated to such Partner only that amount of Losses as will not create or increase an Adjusted Capital Account Deficit. The Losses that would, absent the application of the preceding sentence, otherwise be allocated
to such Partner shall be allocated to the other Partners in accordance with their respective interests in the Partnership as determined by the General Partner in its reasonable discretion. 

(e) Profits and Losses described in clause (e) of the definition of Profits and Losses shall be allocated in a manner consistent
with the manner that the adjustments to the Capital Accounts are required to be made pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(j) and (m). 

(f) The allocations set forth in Section 5.03(a) through and including Section 5.03(d)
(the “Regulatory Allocations”) are intended to comply with certain requirements of Sections 1.704-1(b) and 1.704-2 of the Treasury Regulations. The Regulatory Allocations may not be consistent with the manner in which
the Partners intend to allocate Profit and Loss of the Partnership or make Distributions. Accordingly, notwithstanding the other provisions of this Article V, but subject to the Regulatory Allocations, income, gain, deduction and loss shall
be reallocated among the Partners so as to eliminate the effect of the Regulatory Allocations and thereby cause the respective Capital Accounts of the Partners to be in the amounts (or as close thereto as possible) that they would have been if
Profit and Loss (and such other items of income, gain, deduction and loss) had been allocated without reference to the Regulatory Allocations. In general, the Partners anticipate that the foregoing will be accomplished by specially allocating other
Profit and Loss (and such other items of income, gain, deduction and loss) among the Partners so that the net amount of the Regulatory Allocations and such special allocations to each such Partner is zero. In addition, if in any Taxable Year or
other Fiscal Period there is a decrease in Partnership Minimum Gain, or in Partner Minimum Gain, and application of the minimum gain chargeback requirements set forth in Section 5.03(a) or
Section 5.03(b) would cause a distortion in the economic arrangement among the Partners, the Partners may, if they do not expect that the Partnership will have sufficient other income to correct such distortion, request the
Internal Revenue Service to waive either or both of such minimum gain chargeback requirements. If such request is granted, this Agreement shall be applied in such instance as if it did not contain such minimum gain chargeback requirement. 

(g) Notwithstanding any other provision of this Agreement, Profits (and if necessary items of gross income or gain) for any Taxable Year or
other Fiscal Period shall be allocated to each Series A Preferred Unitholder up to the amount of any Series A Quarterly Distribution that is paid in cash, and any such Distribution shall not be treated, for U.S. federal income tax purposes, as a
guaranteed payment for the use of capital pursuant to Section 707(c) of the Code. 

  
 38 

 Section 5.04 Tax Allocations. 

(a) The income, gains, losses, deductions and credits of the Partnership will be allocated, for U.S. federal (and applicable state and local)
income tax purposes, among the Partners in accordance with the allocation of such income, gains, losses, deductions and credits among the Partners for computing their Capital Accounts; provided, that if any such allocation is not permitted by
the Code or other applicable Law, the Partnership’s subsequent income, gains, losses, deductions and credits will be allocated among the Partners so as to reflect as nearly as possible the allocation set forth herein in computing their Capital
Accounts. 
 (b) Items of Partnership taxable income, gain, loss and deduction with respect to any property contributed to the capital of
the Partnership shall be allocated among the Partners in accordance with Code Section 704(c) so as to take account of any variation between the adjusted basis of such property to the Partnership for U.S. federal income tax purposes and its Book
Value using the “traditional method”, as described in Treasury Regulations Section 1.704-3(b). 
 (c) If the Book Value of
any Partnership asset is adjusted pursuant to Section 5.01, subsequent allocations of items of taxable income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted
basis of such asset for U.S. federal income tax purposes and its Book Value in the same manner as under Code Section 704(c) using the “traditional method”, as described in Treasury Regulations Section 1.704-3(b). 

(d) If, as a result of an exercise of a noncompensatory option (including the Warrants) to acquire an interest in the Partnership, a Capital
Account reallocation is required under Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(3), the Partnership shall make corrective allocations pursuant to Treasury Regulations Section 1.704-1(b)(4)(x). 

(e) Allocations of tax credits, tax credit recapture and any items related thereto shall be allocated to the Partners pro rata as
determined by the General Partner taking into account the principles of Treasury Regulations Section 1.704-1(b)(4)(ii). 
 (f) For
purposes of determining a Partner’s pro rata share of the Partnership’s “excess nonrecourse liabilities” within the meaning of Treasury Regulations Section 1.752-3(a)(3), each Partner’s interest in income and
gain shall be in proportion to its interest in the Partnership as determined by the General Partner in its reasonable discretion. 
 (g)
Allocations pursuant to this Section 5.04 are solely for purposes of U.S. federal (and applicable state and local) income taxes and shall not affect, or in any way be taken into account in computing, any Partner’s
Capital Account or share of Profits, Losses, Distributions or other Partnership items pursuant to any provision of this Agreement. 

Section 5.05 Withholding; Indemnification and Reimbursement for Payments on Behalf of a Partner. The
Partnership and its Subsidiaries may withhold from Distributions, allocations or portions thereof if it is required to do so by any applicable Law, and each Partner hereby authorizes the Partnership and its Subsidiaries to withhold or pay on behalf
of or with respect to such Partner any amount of U.S. federal, state or local or non-U.S. taxes that the General Partner determines, in good faith, that the Partnership or any of its Subsidiaries is required
to withhold or pay with respect to any amount distributable or allocable to such Partner pursuant to this Agreement. In addition, if the Partnership is obligated to pay any other amount to a Governmental Entity (or otherwise makes a payment to a
Governmental Entity) that is specifically attributable to a Partner (including U.S. federal income taxes as a result of Partnership obligations pursuant to the Revised 

  
 39 

 
Partnership Audit Provisions with respect to items of income, gain, loss deduction or credit allocable or attributable to such Partner, state personal property taxes and state unincorporated
business taxes, but excluding payments such as professional association fees and the like made voluntarily by the Partnership on behalf of any Partner based upon such Partner’s status as an employee of the Partnership), then such tax shall be
treated as an amount of taxes withheld or paid with respect to such Partner pursuant to this Section 5.05. For all purposes under this Agreement, any amounts withheld or paid with respect to a Partner pursuant to this
Section 5.05 shall be treated as having been distributed to such Partner at the time such withholding or payment is made. Further, to the extent that the cumulative amount of such withholding or payment for any period
exceeds the Distributions to which such Partner is entitled for such period, such Partner shall indemnify the Partnership in full for the amount of such excess. The General Partner may offset Distributions to which a Person is otherwise entitled
under this Agreement against such Person’s obligation to indemnify the Partnership under this Section 5.05. A Partner’s obligation to indemnify the Partnership under this Section 5.05
shall survive the termination, dissolution, liquidation and winding up of the Partnership, and for purposes of this Section 5.05, the Partnership shall be treated as continuing in existence. The Partnership may pursue and
enforce all rights and remedies it may have against each Partner under this Section 5.05, including instituting a lawsuit to collect amounts owed under such indemnity with interest accruing from the date such withholding or
payment is made by the Partnership at a rate per annum equal to the sum of the Base Rate (but not in excess of the highest rate per annum permitted by Law). Any income or cash from such indemnity shall not be allocated to or distributed to the
Partner paying such indemnity. Each Partner hereby agrees to furnish to the Partnership such information and forms as required or reasonably requested in order to comply with any laws and regulations governing withholding of tax or in order to claim
any reduced rate of, or exemption from, withholding to which the Partner is legally entitled. 
 ARTICLE VI 

MANAGEMENT 

Section 6.01 Authority of General Partner. 

(a) Except for situations in which the approval of any Limited Partner(s) is specifically required by this Agreement, (i) all management
powers over the business and affairs of the Partnership shall be exclusively vested in the General Partner and (ii) the General Partner shall conduct, direct and exercise full Control over all activities of the Partnership. Except as otherwise
expressly provided for herein and subject to the other provisions of this Agreement, no Limited Partner has the right or power to participate in the management or affairs of the Partnership, nor does any Limited Partner have the power to sign for or
bind the Partnership or deal with third parties on behalf of the Partnership without the consent of the General Partner. 
 (b) The day-to-day business and operations of the Partnership shall be overseen and implemented by officers of the Partnership (each, an “Officer” and
collectively, the “Officers”), subject to the limitations imposed by the General Partner. An Officer may, but need not, be a Partner. Each Officer shall be appointed by the General Partner and shall hold office until his or
her successor shall be duly designated and shall qualify or until his or her death or until he or she shall resign or shall have been removed in the manner hereinafter provided. Any one Person may hold more than one office. Subject to the other
provisions in this Agreement (including in Section  

  
 40 

 
6.06), the salaries or other compensation, if any, of the Officers of the Partnership shall be fixed from time to time by the General Partner. The authority and responsibility of the
Officers shall include, but not be limited to, such duties as the General Partner may, from time to time, delegate to them and the carrying out of the Partnership’s business and affairs on a day-to-day basis. An Officer may also perform one or more roles as an officer of the General Partner. The General Partner may remove any Officer from office at any time, with or without cause. If any vacancy
shall occur in any office, for any reason whatsoever, then the General Partner shall have the right to appoint a new Officer to fill the vacancy. 

(c) The General Partner shall have the power and authority to effectuate the sale, lease, transfer, exchange or other disposition of any, all
or substantially all of the assets of the Partnership (including the exercise or grant of any conversion, option, privilege or subscription right or any other right available in connection with any assets at any time held by the Partnership) or the
merger, consolidation, reorganization or other combination of the Partnership with or into another entity. 
 (d) Notwithstanding any other
provision of this Agreement, neither the General Partner nor any Officer authorized by the General Partner shall have the authority, on behalf of the Partnership, either directly or indirectly, without the prior approval of each Partner, to take any
action that would result in the failure of the Partnership to be taxable as a partnership for purposes of U.S. federal income tax, or take any position inconsistent with treating the Partnership as a partnership for purposes of U.S. federal income
tax, except as required by Law. 
 (e) Notwithstanding any other provision of this Agreement, neither the General Partner nor any Officer
authorized by the General Partner shall, on behalf of the Partnership, and the Partnership shall not, in each case, either directly or indirectly, without the prior approval of Series A Preferred Unitholders representing the Series A Required Voting
Percentage, take any of the following actions: 
 (i) amend, alter, modify or repeal the Certificate or this Agreement (including in
connection with any merger or consolidation or any of the transactions contemplated by Section 11.01) in any manner that is adverse to any of the rights, preferences or privileges of the Series A Preferred Units;
provided that an amendment to this Agreement to provide for the issuance of Series A Junior Securities pursuant to any stock incentive plans of the Corporation and that does not otherwise alter, change or affect any express rights,
preferences or privileges of the Series A Preferred Unitholders shall be deemed not adverse to the rights, preferences or privileges of the Series A Preferred Units; 

(ii) convert the Partnership into a corporation, or take any other action resulting in the Partnership being treated as a corporation for
federal income tax purposes; 
 (iii) issue any additional Series A Preferred Units or any Series A Parity Securities or Series A Senior
Securities or any securities convertible into or evidencing the right to purchase any Series A Parity Securities or Series A Senior Securities (other than Series A PIK Units); 

  
 41 

 (iv) permit any Subsidiary of the Partnership to issue any equity interests (other than
equity interests issued to the Partnership or a wholly-owned Subsidiary of the Partnership); 
 (v) (A) (1) on or prior to the earlier
of (x) the last day of the Quarter in which the Initial Period expires and (y) March 31, 2020, incur any Indebtedness or permit any Subsidiary of the Partnership to incur any Indebtedness that would not be permitted to be incurred
under the terms of the Existing Credit Agreement; provided that the Partnership may incur additional pari passu revolving credit facility Indebtedness in accordance with the terms of the Credit Agreement, and (2) at any time
thereafter, incur any Indebtedness or permit any Subsidiary of the Partnership to incur any Indebtedness that would cause the Partnership’s Total Leverage Ratio to exceed (x) 5.25x on a pro forma basis for such incurrence or (y) 5.5x on a pro
forma basis for such incurrence during any Acquisition Period (as such term is defined in the Existing Credit Agreement) or (B) otherwise incur any Indebtedness in respect of which APA or any of its Affiliates (other than the Partnership and
its Subsidiaries) is a lender, other than (with respect to this clause (B)) Indebtedness the proceeds of which are used to redeem one hundred percent (100%) of the outstanding Series A Preferred Units in cash and other Indebtedness so long
as, subject to the remainder of this Section 6.01(e)(v), (1) the aggregate principal amount thereof does not exceed $50 million at any time, (2) such Indebtedness does not provide for payments of interest, fees
and other non-principal amounts greater than the lesser of (x) ten percent (10%) of the outstanding principal amount in the aggregate per year and (y) such amount as would be obtainable in an
arms’-length transaction, (3) such Indebtedness is otherwise on arms’-length terms or terms more favorable, in the aggregate, to the Partnership and its Subsidiaries and (4) solely in the event that the Partnership seeking
repayment of such Indebtedness in cash would prevent the Partnership from being able to redeem each Series A Preferred Unit in full in cash at the Series A Redemption Price as a result of insufficient cash of the Partnership at such time, such
Indebtedness automatically converts immediately prior to such redemption into Series A Preferred Units or other Equity Securities junior in all respects to the Series A Preferred Units; 

(vi) sell, exchange or otherwise dispose of any interest in any Existing Pipeline Joint Venture unless (A) the proceeds therefrom are in
cash, (B) one hundred percent (100%) of such proceeds are used to offer to redeem outstanding Series A Preferred Units, applying the procedures of Section 11.04(d), and (C) such sale, exchange or other disposition
and redemption of Series A Preferred Units do not violate the terms of the Credit Agreement; 
 (vii) permit the Partnership or any
Subsidiary thereof to exercise any right to vote in favor of, or waive any of its voting or other rights with respect to, the incurrence of Indebtedness by any Existing Pipeline Joint Venture; 

(viii) declare or pay any dividend or Distributions on, or redeem or repurchase (including pursuant to any of the transactions contemplated by
Section 11.01), any Series A Junior Securities other than the following Distributions, redemptions or repurchases to the extent solely attributable to Cash from Ordinary Course Operations and otherwise permitted pursuant to
the terms of the Existing Credit Agreement (provided that the “Total Leverage Ratio” used to test leverage ratios will be based on the Total Leverage Ratio defined in this Agreement): 

(A) Distributions, redemptions or repurchases occurring prior to the fifth (5th) anniversary of the Series A Issue Date up to an amount not to
exceed $650 million in the aggregate for such period; 

  
 42 

 (B) Distributions, redemptions or repurchases (1) occurring on or after the fourth
(4th) anniversary of the Series A Issue Date but prior to the fifth (5th) anniversary of the Series A Issue Date that are made at such time when the Total Leverage Ratio of the Partnership is less than or equal to 4.5x or (2) occurring on or
after the fifth (5th) anniversary of the Series A Issue Date that are made at such time when the Total Leverage Ratio of the Partnership is less than or equal to 4.0x (in the case of each of clauses (1) and (2), after giving pro forma effect to
such Distribution, redemption or repurchase), with the definition of “Total Leverage Ratio” being modified solely for purposes of this paragraph to mean: “as of the date of determination, the ratio of (a) the sum of
(i) the consolidated Indebtedness of the Partnership and its Subsidiaries (other than Unrestricted Subsidiaries (as defined in the Existing Credit Agreement)) plus (ii) the aggregate Series A Investment Amount in respect of all
outstanding Series A Preferred Units, and in the case of (i) and (ii), on the date of such calculation to (b) EBITDA of the Partnership and its Subsidiaries (other than Unrestricted Subsidiaries (as defined in the Existing
Credit Agreement)) for the twelve (12) months ending immediately before such date”; and 
 (C) Distributions on Series A Junior
Securities paid in-kind in Series A Junior Securities; 
 (ix) enter into any agreement that
expressly prohibits the declaration or payment of dividends or Distributions on, or redemptions or repurchases of, the Series A Preferred Units, other than entry into any agreement providing for Indebtedness to the extent permitted by the terms of
the Credit Agreement and the other terms and conditions of this Agreement; 
 (x) take any action to (A) liquidate or dissolve the
Partnership outside of a bankruptcy proceeding unless, in connection with such transaction, each Series A Preferred Unit outstanding is redeemed in full in cash at the Series A Redemption Price for such Series A Preferred Unit or (B) commence
or consent to any bankruptcy or other similar proceeding (excluding, for avoidance of doubt, any proceeding referenced in preceding clause (A)) unless the Series A Preferred Units are redeemed in full in cash at the Series A Redemption Price
prior to commencing such transaction; 
 (xi) enter into any agreement to effect a Series A Change of Control unless the Partnership would
have sufficient funds to redeem the Series A Preferred Units upon consummation thereof, it being understood that the foregoing shall not limit the rights of the Series A Preferred Unitholders under Section 11.04(c) with
respect to such Series A Change of Control; 
 (xii) amend this Agreement to change the Series A Purpose or pursue any activities not
related to the Series A Purpose or otherwise enter into or invest in any line of business not related to the Series A Purpose; 

  
 43 

 (xiii) enter into, amend or terminate any agreement, or engage in any other transaction or
series of related transactions, in each case, involving the Partnership or any of its Subsidiaries, on the one hand, and any Affiliate of the Partnership that is not Controlled by the Partnership (other than the General Partner) or any Limited
Partner or any Affiliate of such Limited Partner, on the other hand, unless such action (A) is not required to be approved by the conflicts committee of the Corporate Board pursuant to the Corporation Related Party Transaction Policy and
Procedures or (B) is approved by the conflicts committee of the Corporate Board pursuant to the Corporation Related Party Transaction Policy and Procedures; 

(xiv) permit any of the Subsidiaries of the Partnership to effect any of the foregoing; or 

(xv) enter into any agreement or otherwise commit to do any of the foregoing. 

In addition to the matters expressly set forth in the preceding clauses of this Section 6.01(e), each other matter
that expressly requires approval of Series A Preferred Unitholders representing the Series A Required Voting Percentage pursuant to this Agreement shall not be undertaken by the General Partner, any Officer authorized by the General Partner on
behalf of the Partnership or the Partnership, in each case, either directly or indirectly, without such approval, as applicable. The Series A Preferred Units shall not have the right to vote together with the Common Units or on any matter that is
submitted to the Limited Partners for approval. 
 Section 6.02 Actions of the General Partner. The
General Partner may act through any Officer or through any other Person or Persons to whom authority and duties have been delegated pursuant to Section 6.06. 

Section 6.03 Transfer and Withdrawal of General Partner. 

(a) The General Partner shall not have the right to transfer or assign the General Partner Interest, and the General Partner shall not have
the right to withdraw from the Partnership; provided, that, without the consent of any of the Limited Partners, the General Partner may in good faith, at the General Partner’s expense, be reconstituted as or converted into a corporation,
partnership or other form of entity (any such reconstituted or converted entity being deemed to be the General Partner for all purposes hereof) by merger, consolidation, conversion or otherwise, or transfer or assign the General Partner Interest (in
whole or in part) to one of its Affiliates that is a wholly owned Subsidiary of the Corporation so long as such other entity or Affiliate shall have assumed in writing the obligations of the General Partner under this Agreement. In the event of an
assignment or other transfer of all of the General Partner Interest in accordance with this Section 6.03, such assignee or transferee shall be substituted in the General Partner’s place as general partner of the
Partnership and immediately thereafter the General Partner shall withdraw as a general partner of the Partnership (but shall remain entitled to exculpation and indemnification pursuant to Section 6.07 and
Section 7.04 with respect to events occurring on or prior to such date). 
 (b) Except as otherwise contemplated
by Section 6.03(a), no assignee or transferee shall become the general partner of the Partnership by virtue of such assignee’s or transferee’s receiving all or a portion of any interest in the Partnership from the
General Partner or another assignee or transferee from the General Partner without the written consent of all of the Common Unitholders to such substitution, which consent may be given or withheld, or made subject to such conditions as each Common
Unitholder deems appropriate in its sole discretion. 

  
 44 

 Section 6.04 Transactions Between Partnership and
General Partner. The General Partner may cause the Partnership to contract and deal with the General Partner, or any Affiliate of the General Partner; provided, that such contracts and dealings are on terms comparable to and competitive
with those available to the Partnership from others dealing at arm’s length or are approved by the Common Unitholders holding a majority of the Common Units (excluding Common Units held by the General Partner and its Controlled Affiliates) then
outstanding, the Series A Preferred Unitholders representing the Series A Required Voting Percentage then outstanding and otherwise are permitted by the Credit Agreement. 

Section 6.05 Reimbursement for Expenses. The Limited Partners acknowledge and agree that the General Partner
is and will continue to be a wholly owned Subsidiary of the Corporation, whose Class A Common Stock is and will continue to be publicly traded, and therefore the General Partner and the Corporation will have access to the public capital markets
and that such status and the services performed by the General Partner will inure to the benefit of the Partnership and all Limited Partners. Therefore, the General Partner and the Corporation shall be reimbursed by the Partnership for any
reasonable out-of-pocket expenses incurred on behalf of the Partnership, including all fees, expenses and costs of the Corporation being a public company (including
public reporting obligations, proxy statements, stockholder meetings, stock exchange fees, transfer agent fees, SEC and FINRA filing fees and offering expenses) and maintaining its corporate existence. In the event that (a) shares of
Class A Common Stock are sold to underwriters in any public offering at a price per share that is lower than the price per share for which such shares of Class A Common Stock are sold to the public in such public offering after taking into
account underwriters’ discounts or commissions and brokers’ fees or commissions (such difference, the “Discount”) and (b) the proceeds from such public offering are used to fund the Cash Settlement for any
Common Redeemed Units or otherwise contributed to the Partnership, the Partnership shall reimburse the Corporation for such Discount by treating such Discount as an additional Capital Contribution made by the Corporation to the Partnership, issuing
Common Units in respect of such deemed Capital Contribution in accordance with Section 11.02, and increasing the Corporation’s Capital Account by the amount of such Discount. To the extent practicable, expenses
incurred by the General Partner or the Corporation on behalf of or for the benefit of the Partnership shall be billed directly to and paid by the Partnership and allocable to the Common Unitholders to the extent permitted by
Section 5.02, and, if and to the extent any reimbursements to the General Partner or the Corporation or any of their respective Affiliates by the Partnership pursuant to this Section 6.05
constitute gross income to such Person (as opposed to the repayment of advances made by such Person on behalf of the Partnership), such amounts shall be treated as “guaranteed payments” within the meaning of Code Section 707(c) and
shall not be treated as Distributions for purposes of computing the Limited Partners’ Capital Accounts. 

Section 6.06 Delegation of Authority. The General Partner (a) may, from time to time, delegate to one or
more Persons such authority and duties as the General Partner may deem advisable and (b) may assign titles (including chief executive officer, president, chief executive officer, chief financial officers, chief operating officer, vice
president, secretary, assistant secretary, treasurer or assistant treasurer) and delegate certain authority and duties to such Persons as the same may be amended, restated or otherwise modified from time to time. Any number of titles may be held by
the same individual. The salaries or other compensation, if any, of such agents of the Partnership shall be fixed from time to time by the General Partner, subject to the other provisions in this Agreement. 

  
 45 

 Section 6.07 Limitation of Liability of the General
Partner. 
 (a) Except as otherwise provided herein (including Section 6.10) or in an agreement entered into
by such Person and the Partnership, neither the General Partner nor any of the General Partner’s Affiliates shall be liable to the Partnership or to any Partner that is not the General Partner for any act or omission performed or omitted by the
General Partner in its capacity as the general partner of the Partnership pursuant to authority granted to the General Partner by this Agreement; provided, however, that, except as otherwise provided herein, such limitation of
liability shall not apply to the extent the act or omission was attributable to the General Partner’s bad faith, willful misconduct or violation of Law in which the General Partner acted with knowledge that its conduct was unlawful, or for any
present or future breaches of any representations, warranties, covenants or obligations by the General Partner or its Affiliates contained herein or in the other agreements with the Partnership. The General Partner may exercise any of the powers
granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and, subject to Section 6.10, shall not be responsible for any misconduct or negligence on
the part of any such agent (so long as such agent was selected in good faith and with reasonable care). The General Partner shall be entitled to rely upon the advice of legal counsel, independent public accountants and other experts, including
financial advisors, and, Section 6.10, any act of or failure to act by the General Partner in good faith reliance on such advice shall in no event subject the General Partner to liability to the Partnership or any Partner
that is not the General Partner. 
 (b) Subject to Section 6.10, whenever this Agreement or any other agreement
contemplated herein provides that the General Partner shall act in a manner which is, or provide terms which are, “fair and reasonable” to the Partnership or any Partner that is not the General Partner, the General Partner shall determine
such appropriate action or provide such terms considering, in each case, the relative interests of each party to such agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry
practices, and any applicable United States generally accepted accounting practices or principles. 
 (c) Subject to
Section 6.10, whenever in this Agreement or any other agreement contemplated herein, the General Partner is permitted or required to take any action or to make a decision in its “sole discretion” with
“complete discretion” or under a grant of similar authority or latitude, the General Partner shall be entitled to consider such interests and factors as it desires, including its own interests, and shall, to the fullest extent permitted by
applicable Law, have no duty or obligation to give any consideration to any interest of or factors affecting the Partnership or other Partners. 

(d) Subject to Section 6.10, whenever in this Agreement the General Partner is permitted or required to take any
action or to make a decision in its “reasonable discretion,” “good faith” or under another express standard, the General Partner shall act under such express standard and, to the fullest extent permitted by applicable Law, shall
not be subject to any other or different standards imposed by this Agreement or any other agreement contemplated herein, and so long as the General Partner acts in good faith, the resolution, action or terms so made, taken or provided by the General
Partner shall not constitute a breach of this Agreement or any other agreement contemplated herein or impose liability upon the General Partner or any of the General Partner’s Affiliates. 

  
 46 

 Section 6.08 Investment Company Act. The General Partner
shall use its best efforts to ensure that the Partnership shall not be subject to registration as an investment company pursuant to the Investment Company Act. 

Section 6.09 Activities of the Corporation and the General Partner. 

(a) The Corporation and the General Partner shall not, and the Corporation shall not cause or permit the General Partner to, directly or
indirectly, enter into or conduct any business or operations, other than, as applicable, in connection with (a) the ownership, acquisition and disposition of Common Units, (b) the management of the business and affairs of the Partnership
and its Subsidiaries, (c) the operation of the Corporation as a reporting company with a class (or classes) of securities registered under Section 12 of the Exchange Act and listed on a securities exchange, (d) the offering, sale,
syndication, private placement or public offering of stock, bonds, securities or other interests, (e) financing or refinancing of any type related to the Partnership, its Subsidiaries or their assets or activities and (f) such activities
as are incidental to the foregoing; provided, however, that, except as otherwise provided herein, the net proceeds of any sale of Equity Securities of the Corporation pursuant to the preceding clauses (d) and (e)
shall be made available to the Partnership as Capital Contributions and the proceeds of any other financing raised by the Corporation pursuant to the preceding clauses (d) and (e) shall be made available to the
Partnership as loans or otherwise as appropriate; provided, further, that the Corporation may, with approval of Series A Preferred Unitholders representing a majority of the outstanding Series A Preferred Units (excluding any Series A
Preferred Units held by APA, the Corporation, the Contributor, the General Partner and any of their respective Controlled Affiliates), from time to time hold or acquire assets in its own name or otherwise other than through the Partnership and its
Subsidiaries so long as the Corporation takes all necessary measures to ensure that the economic benefits and burdens of such assets are otherwise vested in the Partnership or its Subsidiaries, through assignment, mortgage loan or otherwise. Subject
to Section 6.01(e), nothing contained herein shall be deemed to prohibit the General Partner from executing any guarantee of indebtedness of the Partnership or its Subsidiaries. 

(b) The Corporation shall not amend, alter, modify or repeal the Corporation Related Party Transaction Policy and Procedures without the prior
written consent of Series A Preferred Unitholders holding a majority of the outstanding Series A Preferred Units (excluding any Series A Preferred Units held by APA, the Corporation, the Contributor, the General Partner and any of their respective
Controlled Affiliates). 
 (c) At any time during which both (i) Series A Preferred Units having an aggregate Series A Issue Price of
at least $100 million are outstanding and (ii) Magnetar Financial LLC, CALTM Holdings, LLC or their respective Affiliates continue to own an aggregate of at least fifty percent (50%) of the outstanding Series A Preferred Units, such Series
A Preferred Unitholders shall have the right to designate from time to time to the Corporate Board one (1) observer who is not an officer, employee or Affiliate of a Competitor (the “Board Observer”). The initial Board
Observer shall be designated by Magnetar Financial LLC in its sole discretion; provided that, after such appointment by Magnetar Financial LLC, such initial Board Observer may be removed or replaced at any time after the Effective Time by the
approval of a majority of the outstanding Series A Preferred Units held by Magnetar Financial LLC, CALTM Holdings, LLC and their respective Affiliates and notice of the same to the Corporation. The Board Observer shall be

  
 47 

 
permitted to attend each meeting of the Corporate Board and of the conflicts committee of the Corporate Board (but excluding meetings of any other committees of the Corporate Board) in a non-voting observer capacity on behalf of the Series A Preferred Unitholders and may, at its sole cost and expense, attend any such meeting of the conflicts committee of the Corporate Board with legal counsel to the
extent such meeting will (or is expected to) cover any matter that is, or could reasonably be expected to be, material to the Series A Preferred Unitholders. The Board Observer shall be permitted to discuss the information presented at any meeting
of the Corporate Board or conflicts committee thereof, and in the event any materials presented to the Corporate Board or conflicts committee are permitted to be removed from such meeting, to share such materials, with the Series A Preferred
Unitholders in accordance with, and subject to, this Agreement. Such Board Observer’s attendance at any meeting of the Corporate Board in his or her capacity as such shall be conditioned upon the execution and delivery to the Corporation by
such Board Observer of a confidentiality agreement in the form attached hereto as Exhibit B. With respect to matters relayed by the Board Observer to the Series A Preferred Unitholders, the Series A Preferred Unitholders shall be subject to
the confidentiality provisions set forth in Section 16.02. Each of Magnetar Financial LLC and CALTM Holdings, LLC shall be severally, but not jointly, responsible for the failure of any Board Observer that is Affiliated
with or otherwise a Representative nominated by such Person to at all times maintain the confidentiality of any confidential information related to APA, the Corporation, or any of their respective Subsidiaries received by such Board Observer in his
or her capacity as the Board Observer in accordance with such obligation of confidentiality. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the chairperson of any meeting of the Corporate Board or conflicts
committee thereof may exclude the Board Observer from access to any materials or meeting or portion thereof, to the extent such materials or meeting or portion thereof directly relates to a matter that, (i) in the advice of the
Corporation’s outside counsel, could reasonably be expected to result in the loss of attorney-client privilege or a conflict of interest with the Corporation, or (ii) in the sole discretion of such chairperson, constitutes sensitive or
proprietary information regarding existing or potential businesses, properties, or business opportunities of APA, the Corporation, or any of their respective Subsidiaries, to the extent not required to be approved by the conflicts committee of the
Corporate Board pursuant to the Corporation Related Party Transaction Policy and Procedures; provided that such exclusion shall be limited to the portion of such materials or meeting that is the basis for such exclusion. 

Section 6.10 Standard of Care. The General Partner shall, in connection with the performance of its duties in
its capacity as the General Partner, have the same fiduciary duties to the Partnership and the Partners as would be owed to a Delaware corporation and its stockholders by its directors, and shall be entitled to the benefit of the same presumptions
in carrying out such duties as would be afforded to a director of a Delaware corporation (as such duties and presumptions are defined, described and explained under the Laws of the State of Delaware as in effect from time to time). The provisions of
this Agreement, to the extent that they restrict or eliminate the duties (including fiduciary duties) and liabilities of the General Partner otherwise existing at law or in equity, are agreed by the Partners to replace, to the fullest extent
permitted by applicable Law, such other duties and liabilities of the General Partner. 
 Section 6.11 Certain
Compliance Matters. The Partnership shall maintain in effect policies and procedures designed to achieve compliance by the Partnership, its Subsidiaries and their respective directors, officers, employees and agents (acting in their capacity as
such) with applicable Anti-Corruption Laws and Sanctions. The Partnership and each of its Subsidiaries shall comply with all applicable Anti-Corruption Laws and Sanctions in all material respects.

 ARTICLE VII 

RIGHTS AND OBLIGATIONS OF PARTNERS 

Section 7.01 Limitation of Liability and Duties of Partners; Investment Opportunities. 

(a) Except as provided in this Agreement or in the Delaware Act, no Partner (including the General Partner) shall be obligated personally for
any debt, obligation, or liability solely by reason of being a Partner or acting as the General Partner of the Partnership; provided, that, in the case of the General Partner, this sentence shall not in any manner limit the liability of the
General Partner to the Partnership or any Partner (other than the General Partner) attributable to a breach by the General Partner of any obligations of the General Partner under this Agreement. Notwithstanding anything contained herein to the
contrary, the failure of the Partnership to observe any formalities or requirements relating to the exercise of its powers or management of its business and affairs under this Agreement or the Delaware Act shall not be grounds for imposing personal
liability on the Partners for liabilities of the Partnership. 
 (b) In accordance with the Delaware Act and the laws of the State of
Delaware, a Partner may, under certain circumstances, be required to return amounts previously distributed to such Partner. It is the intent of the Partners that no Distribution to any Partner pursuant to Article IV shall be deemed a return
of money or other property paid or distributed in violation of the Delaware Act. The payment of any such money or Distribution of any such property to a Partner shall be deemed to be a compromise within the meaning of
Section 17-502(b) of the Delaware Act, and, to the fullest extent permitted by Law, any Partner receiving any such money or property shall not be required to return any such money or property to the
Partnership or any other Person. However, if any court of competent jurisdiction holds that, notwithstanding the provisions of this Agreement, any Partner is obligated to make any such payment, such obligation shall be the obligation of such Partner
and not of any other Partner. 
 (c) Notwithstanding any other provision of this Agreement (subject to
Section 6.07 and except as set forth in Section 6.10, in each case with respect to the General Partner), to the extent that, at law or in equity, any Partner (or such Partner’s Affiliate or
any manager, managing member, general partner, director, officer, employee, agent, fiduciary or trustee of such Partner or of any Affiliate of such Partner (each Person described in this parenthetical, a “Related Person”))
has duties (including fiduciary duties) to the Partnership, to another Partner (including the General Partner), to any Person who acquires an interest in a Limited Partner Interest or to any other Person bound by this Agreement, all such duties
(including fiduciary duties) are hereby eliminated, to the fullest extent permitted by law, and replaced with the duties or standards expressly set forth herein, if any. The elimination of duties (including fiduciary duties) to the Partnership, each
of the Partners (including the General Partner), each other Person who acquires an interest in a Limited Partner Interest and each other Person bound by this Agreement and replacement thereof with the duties or standards expressly set forth herein,
if any, are approved by the Partnership, each of the Partners (including the General Partner), each other Person who acquires an interest in a Limited Partner Interest and each other Person bound by this Agreement. 

  
 49 

 (d) Subject to the terms of Section 7.01(e), each Unrestricted
Person (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or
description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member,
and none of the same shall constitute a breach of this Agreement or any duty otherwise existing at law, in equity or otherwise, to any Group Member or any Partner; provided such Unrestricted Person does not engage in such business or activity
using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person. None of any Group Member, any Limited Partner or any other Person shall have any rights by virtue of this Agreement, any Group
Member Agreement, or the partnership relationship established hereby in any business ventures of any Unrestricted Person. 
 (e) Subject to
the terms of Section 6.09 and Section 7.01(d), but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Unrestricted Person
(other than the General Partner) in accordance with the provisions of this Section 7.01 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of any duty otherwise existing
at law, in equity or otherwise, of the General Partner or any other Unrestricted Person for the Unrestricted Persons (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the
Partnership and (iii) the Unrestricted Persons shall have no obligation hereunder or as a result of any duty otherwise existing at law, in equity or otherwise, to present business opportunities to the Partnership. Notwithstanding anything to
the contrary in this Agreement, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Unrestricted Person (including the General Partner). No Unrestricted Person (including the General Partner) who acquires
knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Unrestricted Person (including the
General Partner) shall not be liable to the Partnership, to any Limited Partner or any other Person bound by this Agreement for breach of any duty otherwise existing at law, in equity or otherwise, by reason of the fact that such Unrestricted Person
(including the General Partner) pursues or acquires for itself, directs such opportunity to another Person or does not communicate such opportunity or information to the Partnership, provided such Unrestricted Person does not engage in such business
or activity using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person. 

Section 7.02 Lack of Authority. No Partner, other than the General Partner or a duly appointed Officer, in
each case in its capacity as such, has the authority or power to act for or on behalf of the Partnership, to do any act that would be binding on the Partnership or to make any expenditure on behalf of the Partnership. The Partners hereby consent to
the exercise by the General Partner of the powers conferred on them by Law and this Agreement. 
 Section 7.03
No Right of Partition. No Partner, other than the General Partner, shall have the right to seek or obtain partition by court decree or operation of Law of any Partnership property, or the right to own or use particular or individual assets of
the Partnership. 

  
 50 

 Section 7.04 Indemnification. 

(a) Subject to Section 5.05, the Partnership hereby agrees to indemnify and hold harmless any Person (each an
“Indemnified Person”) to the fullest extent permitted under the Delaware Act, as the same now exists or may hereafter be amended, substituted or replaced (but, in the case of any such amendment, substitution or replacement
only to the extent that such amendment, substitution or replacement permits the Partnership to provide broader indemnification rights than the Partnership is providing immediately prior to such amendment), against all expenses, liabilities and
losses (including attorneys’ fees, judgments, fines, excise taxes or penalties) reasonably incurred or suffered by such Person (or one or more of such Person’s Affiliates) by reason of the fact that such Person is or was a Partner or is or
was serving as the General Partner, Officer, employee or other agent of the Partnership or is or was serving at the request of the Partnership as a manager, officer, director, principal, member, employee or agent of another corporation, partnership,
joint venture, limited liability company, trust or other enterprise; provided, however, that no Indemnified Person shall be indemnified for any expenses, liabilities and losses suffered that are attributable to such Indemnified
Person’s willful misconduct or violation of Law in which such Indemnified Person acted with knowledge that its conduct was unlawful; provided, further, that no Indemnified Person shall be indemnified for any expenses, liabilities
and losses suffered that are attributable to any proceeding among Partners. Expenses, including attorneys’ fees, incurred by any such Indemnified Person in defending a proceeding shall be paid by the Partnership in advance of the final
disposition of such proceeding, including any appeal therefrom, upon receipt of an undertaking by or on behalf of such Indemnified Person to repay such amount if it shall ultimately be determined that such Indemnified Person is not entitled to be
indemnified by the Partnership. 
 (b) The right to indemnification and the advancement of expenses conferred in this
Section 7.04 shall not be exclusive of any other right which any Person may have or hereafter acquire under any statute, agreement, bylaw, action by the General Partner or otherwise. 

(c) The Partnership shall maintain, or cause to be maintained, directors’ and officers’ liability insurance, or substantially
equivalent insurance, at its expense, to protect any Indemnified Person (and the investment funds, if any, they represent) against any expense, liability or loss described in Section 7.04(a), whether or not the Partnership
would have the power to indemnify such Indemnified Person against such expense, liability or loss under the provisions of this Section 7.04; provided, however, that the Partnership’s inability to obtain,
directly or indirectly, such insurance shall in no way limit or waive its obligations pursuant to this Section 7.04. The Partnership shall use its commercially reasonable efforts to purchase and maintain, or cause to be
purchased and maintained, property and casualty insurance in types and at levels customary for companies of similar size engaged in similar lines of business, as determined in good faith by the General Partner. 

(d) Notwithstanding anything contained herein to the contrary (including in this Section 7.04), the Partnership
agrees that any indemnification and advancement of expenses available to any current or former Indemnified Person from any investment fund that is an Affiliate of the Partnership who served as a director of the Partnership or as a Partner of the
Partnership by virtue of such Person’s service as a member, director, partner or employee of any such fund prior to or following the Effective Time (any such Person, a “Sponsor Person”) shall be secondary to

  
 51 

 
the indemnification and advancement of expenses to be provided by the Partnership pursuant to this Section 7.04, which shall be provided out of and to the extent of
Partnership assets only. No Partner (unless such Partner otherwise agrees in writing or is found in a final decision by a court of competent jurisdiction to have personal liability on account thereof) shall have personal liability on account thereof
or shall be required to make additional Capital Contributions to help satisfy such indemnity of the Partnership. The Partnership (i) shall be the primary indemnitor of first resort for such Sponsor Person pursuant to this
Section 7.04 and (ii) shall be fully responsible for the advancement of all expenses and the payment of all damages or liabilities with respect to such Sponsor Person which are addressed by this
Section 7.04. 
 (e) If this Section 7.04 or any portion hereof shall be invalidated on
any ground by any court of competent jurisdiction, then the Partnership shall nevertheless indemnify and hold harmless each Indemnified Person pursuant to this Section 7.04 to the fullest extent permitted by any applicable
portion of this Section 7.04 that shall not have been invalidated and to the fullest extent permitted by applicable Law. 

Section 7.05 Limited Partners’ Right to Act. For matters that require the approval of the Limited
Partners, the Limited Partners shall act through meetings and written consents as described in paragraphs (a) and (c) below: 

(a) Except with respect to the matters requiring approval of Series A Preferred Unitholders representing the Series A Required Voting
Percentage, acts by the Limited Partners holding a majority of the outstanding Common Units shall be the acts of the Limited Partners. 

(b) Any Limited Partner entitled to vote at a meeting of Limited Partners or consent to an action of the General Partner may authorize another
person or persons to act for it by proxy. An electronic mail, telegram, telex, cablegram or similar transmission by the Limited Partner, or a photographic, photostatic, facsimile or similar reproduction of a writing executed by the Limited Partner
shall (if stated thereon) be treated as a proxy executed in writing for purposes of this Section 7.05(b). No proxy shall be voted or acted upon after eleven (11) months from the date thereof, unless the proxy provides
for a longer period. A proxy shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and that the proxy is coupled with an interest. Should a proxy designate two or more Persons to act as proxies, unless that
instrument shall provide to the contrary, a majority of such Persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all the powers of voting or giving consents thereby conferred, or, if only
one be present, then such powers may be exercised by that one; or, if an even number attend and a majority do not agree on any particular issue, the Partnership shall not be required to recognize such proxy with respect to such issue if such proxy
does not specify how the votes that are the subject of such proxy are to be voted with respect to such issue. 
 (c) The actions by the
Limited Partners permitted hereunder may be taken at a meeting called by the General Partner or by the Limited Partners holding a majority of the Units entitled to vote on such matter on at least forty eight (48) hours’ prior written
notice to the other Limited Partners entitled to vote, which notice shall state the purpose or purposes for which such meeting is being called. The actions taken by the Limited Partners entitled to vote or consent at any meeting (as opposed to by
written consent), however called and noticed, shall be as valid as though taken 

  
 52 

 
at a meeting duly held after regular call and notice if (but not until), either before, at or after the meeting, the Limited Partners entitled to vote or consent as to whom it was improperly held
signs a written waiver of notice or a consent to the holding of such meeting or an approval of the minutes thereof. The actions by the Limited Partners entitled to vote or consent may be taken by vote of the Limited Partners entitled to vote or
consent at a meeting or by written consent, so long as such consent is signed by Limited Partners having not less than the minimum number of Units that would be necessary to authorize or take such action at a meeting at which all Limited Partners
entitled to vote thereon were present and voted. Prompt notice of the action so taken, which shall state the purpose or purposes for which such consent is required and may be delivered via email, without a meeting shall be given to those Limited
Partners entitled to vote or consent who have not consented in writing; provided, however, that the failure to give any such notice shall not affect the validity of the action taken by such written consent. Any action taken pursuant to
such written consent of the Limited Partners shall have the same force and effect as if taken by the Limited Partners at a meeting thereof. 

Section 7.06 Inspection Rights. The Partnership shall permit each Partner and each of its designated
Representatives to visit and inspect (a) the books and records of the Partnership, including its partner ledger and a list of its Partners and (b) the books and records of its Subsidiaries. Additionally, to the extent the Partnership is
permitted, pursuant to the governing documents of a Pipeline Joint Venture, to allow its Partners to visit and inspect the books and records of such Pipeline Joint Venture, upon the written request of a Series A Preferred Unitholder that at such
time holds (together with its Affiliates) Series A Preferred Units having an aggregate Series A Issue Price of at least $100 million, the General Partner shall cause the Partnership to permit such Series A Preferred Unitholder and up to two
(2) of its designated Representatives to accompany the Representatives of the Partnership on a visit and inspection of such Pipeline Joint Venture; provided that such Series A Preferred Unitholder may not so visit and inspect a Pipeline
Joint Venture more than once a year. Each such Series A Preferred Unitholder and its designated Representatives shall execute any confidentiality or similar agreements required by the Partnership or the applicable Pipeline Joint Venture in
connection with such visit and inspection. The Partners have no other inspection rights with respect to any Pipeline Joint Venture unless otherwise agreed to by the General Partner. 

ARTICLE VIII 
 BOOKS, RECORDS,
ACCOUNTING AND REPORTS 
 Section 8.01 Records and Accounting; Other Partnership Information. The
Partnership shall keep, or cause to be kept, appropriate books and records with respect to the Partnership’s business, including all books and records necessary to provide any information, lists and copies of documents required to be provided
pursuant to Section 9.01 or pursuant to applicable Laws. All matters concerning (a) the determination of the relative amount of allocations and Distributions among the Limited Partners pursuant to Articles
III and IV and (b) accounting procedures and determinations, and other determinations not specifically and expressly provided for by the terms of this Agreement, shall be determined by the General Partner in good faith.
Without limiting the foregoing, as long as there are Series A Preferred Units outstanding, the General Partner shall cause the Partnership to deliver (or cause to be delivered) to each Series A Preferred Unitholder the following information, unless
such Series A Preferred Unitholder provides the General Partner with notice to the contrary: 

  
 53

Partnership or the Corporation, as applicable, at the election of the Partnership in respect of any particular fiscal year, either (A) a copy of the audited annual report for such fiscal year for the Partnership and its Subsidiaries, including
therein consolidated balance sheets of the Partnership and its Subsidiaries as of the end of such fiscal year and consolidated statements of earnings and cash flow of the Partnership and its Subsidiaries for such fiscal year, in each case certified
(without qualification) by independent public accountants of nationally recognized standing selected by the Partnership or (B) both (1) a copy of the audited annual report for such fiscal year for the Corporation and its Subsidiaries, including
therein consolidated balance sheets of the Corporation and its Subsidiaries as of the end of such fiscal year and consolidated statements of earnings and cash flow of the Corporation and its Subsidiaries for such fiscal year, in each case certified
(without qualification) by independent public accountants of nationally recognized standing selected by the Corporation (“Corporation Annual Financials”) and (2) unaudited consolidated balance sheets of the Partnership
and its Subsidiaries as of the end of such fiscal year and consolidated statements of earnings and cash flow of the Partnership and its Subsidiaries for such fiscal year (“Partnership Unaudited Annual Financials”);
provided, however, that with respect to Partnership Unaudited Annual Financials, the Partnership shall provide, within thirty (30) days after receipt of a written request of Series A Preferred Unitholders representing the Series A
Required Voting Percentage, a report reconciling all material items between the Corporation Annual Financials and the Partnership Unaudited Annual Financials; 

(ii) within forty five (45) calendar days after the end of each of the first three (3) Quarters of each fiscal year of the
Partnership commencing with the Quarter ending June 30, 2019, unaudited consolidated balance sheets of the Partnership and its Subsidiaries as of the end of such Quarter and consolidated statements of earnings and cash flow of the Partnership
and its Subsidiaries for such Quarter and for the period commencing at the end of the previous fiscal year and ending with the end of such Quarter; 

(iii) reasonably promptly upon written request of such Series A Preferred Unitholder, if the Corporation is no longer subject to the reporting

(iv) a copy of any budgets of the Partnership and its Subsidiaries (and any formal updates thereto) promptly following the approval thereof by
the General Partner; 
 (v) within ten (10) days following the end of each Quarter, a statement detailing the total number of Series A
Preferred Units outstanding (including the number of which are Series A PIK Units), the amount of Series A Unpaid Distributions for each such Series A Preferred Unit and the Series A Distribution Amount as of such time; 

(vi) within ten (10) days following the occurrence of any event directly concerning the Partnership or its Subsidiaries or within ten
(10) days following the discovery by the Partnership of any event directly concerning any of the Pipeline Joint Ventures, in each case, that the General Partner determines in good faith is materially adverse to the Partnership, written notice
of the occurrence of such event and a description thereof; 

  
 54 

 (vii) reasonably promptly upon written request of such Series A Preferred Unitholder, a
current list of the name and last known business, residence or mailing address of each Partner; 
 (viii) reasonably promptly upon written
request of such Series A Preferred Unitholder, a copy of this Agreement and the Certificate of Limited Partnership and all amendments thereto; 

(ix) as promptly as practicable upon availability, copies of any compliance certificate or notice of an event of default delivered pursuant to
the Credit Agreement; and 
 (x) quarterly in-person, or by telephonic or web conference, meetings
between the Series A Preferred Unitholders and their respective Affiliates, on the one hand, and management of the Corporation, the Partnership and their Affiliates, on the other hand, to discuss the principal operating results, financial condition
and forecast and operational activities of the Partnership and its Subsidiaries. 
 Section 8.02 Fiscal
Year. The Fiscal Year of the Partnership shall end on December 31 of each year or such other date as may be established by the General Partner; provided, that the Partnership shall have the same Fiscal Year for accounting purposes as
its Taxable Year for U.S. federal income tax purposes. 
 ARTICLE IX 

TAX MATTERS 

Section 9.01 Preparation of Tax Returns. Contributor shall arrange, at the Partnership’s expense, for
the preparation and timely filing of all tax returns required to be filed by the Partnership. At the reasonable request of the Contributor, each Series A Preferred Unitholder shall provide to the Partnership (a) a schedule setting forth a
reasonable estimate, based on the information in the possession of, or reasonably available to, such Series A Preferred Unitholder or its Affiliates, of the percentage, if any, of the direct and indirect partners, members or owners of Series A
Preferred Units that are Tax-Exempt Partners in the current (or other) Taxable Year and (b) any other information reasonably necessary for the preparation and filing of the Partnership’s tax returns,
in each case, provided that such information is in the possession of, or reasonably available to, the Series A Preferred Unitholder. Contributor shall use reasonable efforts to cause the Partnership to send to each Person who was a Partner at any
time during a Taxable Year, a completed IRS Schedule K-1 within one hundred and eighty (180) days following the end of such Taxable Year. Contributor also shall timely provide each Partner all other
information reasonably requested by a Partner and necessary for the preparation of such Partner’s U.S. federal (and applicable state and local) income tax returns. In addition, Contributor shall cause the Partnership to use commercially
reasonable efforts to provide (a) each Person that was a Series A Preferred Unitholder at any time during a Taxable Year with a good faith estimate of the amounts to be included on such Person’s IRS Schedule
K-1 for such Taxable Year within forty-five (45) days following the end of such Taxable Year, and (b) each other Person that was a Partner at any time during a Taxable Year with a good faith estimate
of the amounts to be included on such Person’s IRS Schedule K-1 for such Taxable Year within sixty (60) days following the end of such Taxable Year. Subject to the terms and conditions of this
Agreement, Contributor shall have the authority 

  
 55 

 
to prepare the tax returns of the Partnership using the elections set forth in Section 9.02 and such other permissible methods and elections as it determines in its
reasonable discretion. Notwithstanding the foregoing, Contributor shall consult in good faith with the Series A Preferred Representative prior to changing any accounting method or making any tax election that would reasonably be expected to have a
disproportionate adverse impact on the Series A Preferred Unitholders. Further, if the impact of such change or election on the Series A Preferred Unitholders also is material, the Series A Preferred Representative shall seek the consent of the
Series A Preferred Unitholders representing the Series A Required Voting Percentage (such consent not to be unreasonably withheld, conditioned or delayed), and the Contributor shall not make such change or election prior to notification by the
Series A Preferred Representative that such consent was obtained. 
 Section 9.02 Tax Elections. The
Partnership and any eligible Subsidiary shall make an election pursuant to Section 754 of the Code, and shall not thereafter revoke such election at any time. In addition, the Partnership (and any eligible Subsidiary) shall make the following
elections on the appropriate forms or tax returns: 
 (a) to adopt the calendar year as the Partnership’s Taxable Year, if permitted
under the Code; 
 (b) to adopt the accrual method of accounting for U.S. federal income tax purposes; and 

(c) to elect to amortize the organizational expenses of the Partnership as permitted by Code Section 709(b). 

Each Partner will upon request supply any information reasonably necessary to give proper effect to any such elections. 

Section 9.03 Texas Margin Tax Sharing Arrangement. If applicable Law requires (a) a Partner (the
“Reporting Partner”) and (b) the Partnership to participate in the filing of a Texas margin tax combined group report, the Partners agree that the Partnership shall be responsible for the Partnership’s Texas margin
tax liability as determined prior to the application of any tax credits or similar tax assets generated by and available to any entity included in the combined group, other than the Partnership (the “Allocable Margin Tax
Liability”). The Partnership’s Allocable Margin Tax Liability shall be equal to (i) the Partnership’s Texas margin tax liability determined on a separate company basis (the “Stand-Alone Margin Tax
Liability”), adjusted upward (if a positive number) or downward (if a negative number) by (ii) the Partnership’s Applicable Share, multiplied by the difference between (A) the sum of the Texas margin tax liability
(determined on a separate company basis) of each separate company in the combined group (the “Total Separate Company Margin Tax Liability”) and (B) the combined group’s Texas margin tax liability;
provided, that the Partnership shall not receive any downward adjustment to its Stand-Alone Margin Tax Liability for any tax credits or similar tax assets generated by and available to any entity included in the combined group, other than the
Partnership. For purposes of this Section 9.03, the term “Applicable Share” means the proportion, expressed as a percentage, that the Partnership’s Stand-Alone Margin Tax Liability bears to
the Total Separate Company Margin Tax Liability. 

  
 56 

 Section 9.04 Tax Controversies. Contributor shall be
designated and may, on behalf of the Partnership, at any time, and without further notice to or consent from any Partner, act as the “partnership representative” of the Partnership, within the meaning given to such term in
Section 6223 of the Code (Contributor, in such capacity, the “Partnership Representative”) for purposes of the Code. The Partnership Representative shall have the right and obligation to take all actions authorized and
required, respectively, by the Code for the Partnership Representative, and is authorized and required to represent the Partnership (at the Partnership’s expense) in connection with all examinations of the Partnership’s affairs by tax
authorities, including resulting administrative and judicial proceedings, and to expend Partnership funds for professional services reasonably incurred in connection therewith. Each Partner agrees to cooperate with the Partnership and to do or
refrain from doing any or all things reasonably requested by the Partnership with respect to the conduct of such proceedings. The Partnership Representative shall use reasonable efforts to (a) notify each of the other Partners upon receipt of
any notice of tax examination of the Partnership by U.S. federal, state or local authorities and (b) keep all Partners informed of material developments with respect to any contacts by or discussions with the tax authorities regarding such tax
examination. Notwithstanding the foregoing, the Partnership Representative shall consult in good faith with the Series A Preferred Representative prior to taking any action (including the settlement or compromise of any examination or resulting
administrative or juridical proceeding) pursuant to this Section 9.04 that would reasonably be expected to have a disproportionate adverse impact on the Series A Preferred Unitholders. Further, if the impact of such action
on the Series A Preferred Unitholders also is material, the Series A Preferred Representative shall seek the consent of the Series A Preferred Unitholders representing the Series A Required Voting Percentage (such consent not to be unreasonably
withheld, conditioned or delayed), and the Partnership Representative shall not take any such action prior to notification by the Series A Preferred Representative that such consent was obtained; provided, that the Series A Preferred
Unitholders will indemnify and hold harmless the Partnership against any additional costs and expenses (including any interest, penalties or additions to tax) borne by the Partnership after the date of the notice of final partnership adjustment in
connection with the related tax examination, audit or similar proceeding as a result of the Series A Preferred Representative’s failure to obtain the required consent. 

ARTICLE X 
 RESTRICTIONS ON
TRANSFER OF UNITS 
 Section 10.01 Transfers of Common Units. 

(a) No holder of Common Units may Transfer any interest in any Common Units, except Transfers (a) pursuant to and in accordance with
Section 10.04 or (b) approved in writing by the General Partner. Notwithstanding the foregoing, “Transfer” shall not include an event that does not terminate the existence of such Limited Partner under
applicable state law (or, in the case of a trust that is a Limited Partner, does not terminate the trusteeship of the fiduciaries under such trust with respect to all the Limited Partner Interests of such trust that is a Limited Partner).
Notwithstanding the foregoing, this Section 10.01 shall not apply to any Common Redemption or Direct Exchange pursuant to Article XI. 

  
 57 

 (b) The restrictions contained in this Section 10.01 shall not
apply to any Transfer of Common Units (each, a “Permitted Transfer”) (i) by a Limited Partner to an Affiliate of such Limited Partner, (ii) by Contributor to the direct or indirect holders of equity interests in
Contributor, (iii) by any transferee pursuant to clause (ii) of this sentence to any Affiliate of such transferee or any trust, family partnership or family limited liability company, the sole beneficiaries, partners or members of
which are such transferee or Relatives of such transferee or (iv) pursuant to a Common Redemption or Direct Exchange in accordance with Article XI; provided, however, that (A) the restrictions contained in this
Agreement will continue to apply to Units after any Permitted Transfer of such Common Units and (B) in the case of the foregoing clauses (i), (ii) and (iii), the transferees of the Common Units so Transferred shall agree in
writing to be bound by the provisions of this Agreement, and the transferor will deliver a written notice to the Partnership and the Partners, which notice will disclose in reasonable detail the identity of the proposed transferee. In the case of a
Permitted Transfer (other than a Common Redemption or Direct Exchange) by any Limited Partner (other than the Corporation) of Common Units to a transferee in accordance with this Section 10.01, such Limited Partner (or any
subsequent transferee of such Limited Partner) shall be required to also transfer a number of shares of Class C Common Stock corresponding to the number of such Limited Partner’s (or subsequent transferee’s) Common Units that were
transferred in the transaction to such transferee; and, in the case of a Common Redemption or Direct Exchange, a number of shares of Class C Common Stock corresponding to the number of such Limited Partner’s Common Units that were
transferred in such Common Redemption or Direct Exchange shall be cancelled. All Permitted Transfers are subject to the additional limitations set forth in Section 10.07(b). 

Section 10.02 Transfers and Drag of Series A Preferred Units. 

(a) Subject to the restrictions set forth in this Section 10.02(a), clauses (iii) and (iv)
of Section 10.02(b), Section 10.04 and Section 10.07(b) and compliance with applicable securities laws, following the first (1st) anniversary of the Series A Issue Date,
holders of Series A Preferred Units may Transfer Series A Preferred Units in accordance with Section 10.04 and Section 10.07(b); provided, that, with respect to any such Transfer prior to
the fifth (5th) anniversary of the Series A Issue Date other than a Series A Preferred Unitholder Permitted Transfer, the Transfer must involve Series A Preferred Units having an aggregate Series
A Issue Price of at least $10 million (or a lesser amount of Series A Preferred Units if such Transfer (i) constitutes all the remaining holdings of such Series A Preferred Unitholder or (ii) has been approved by the General Partner
in its sole discretion). 
 (b) Without the prior written consent of the General Partner, which may be withheld in its sole discretion, no
Series A Preferred Unitholder shall (i) prior to the first (1st) anniversary of the Series A Issue Date, offer, sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any of its Series A Preferred Units, (ii) prior to the third (3rd) anniversary of the Series A Issue Date, directly or indirectly engage in any put or call options or short sales of any equity securities of the Corporation (including the Class A Common Stock)
or the Partnership, (iii) for so long as no Series A Restricted Action has occurred and has not been cured by a Series A Remediation and except for any transfer to another Series A Preferred Unitholder, transfer any Series A Preferred Units to
any Competitor, (iv) effect a direct Transfer of any Series A Preferred Units to any Person (A) other than a United States Person or (B) that is disregarded as separate from its owner for U.S. federal income tax purposes, unless the
regarded owner is a United States Person, including, in each case, by means of any swap or other transaction 

  
 58 

 
or arrangement that directly Transfers or that is designed to, or that might reasonably be expected to, result in the direct Transfer to another, in whole or in part, of any of the economic
consequences of ownership of any Series A Preferred Units, or (v) effect any Transfer of Series A Preferred Units in a manner that violates the terms of this Agreement; provided, that this
Section 10.02(b) shall not restrict (i) any Series A Preferred Unitholder Permitted Transfer that complies with subclauses (iii), (iv) and (v) above or (ii) any Transfer of Series A
Preferred Units made pursuant to an effective registration statement filed pursuant to Section 11.06(c). Notwithstanding the foregoing, any transferee receiving any Series A Preferred Units pursuant to this
Section 10.02(b) shall agree to the restrictions set forth in this Section 10.02(b). For the avoidance of doubt, this Section 10.02 shall not restrict or prohibit any
redemptions, conversions or exchanges made pursuant to and in accordance with Article XI. 
 (c) Prior to any Transfer of Series A
Preferred Units to a Competitor following a Series A Restricted Action, the Series A Preferred Unitholder proposing to make such Transfer shall give the Partnership sixty (60) days’ notice of the anticipated date of such Transfer to give
the Partnership the opportunity to cause a Series A Remediation, it being understood that there is no requirement for such Series A Preferred Unitholder to have an agreement or understanding to effect such Transfer prior to delivering its notice
hereunder. Any Transfer to a Competitor not made in compliance with this Section 10.02(c) shall be void ab initio. 

(d) Notwithstanding anything herein to the contrary, in the event that at any time from and after the fifth (5th) anniversary of the Series A
Issue Date, the Partnership, the Corporation, APA or any of their respective Affiliates offers to redeem, repurchase or otherwise acquire from the Series A Preferred Unitholders all of the Series A Preferred Units outstanding as of such time for an
amount per Series A Preferred Unit that is less than the Series A Redemption Price for such Series A Preferred Unit (the “Series A Preferred Unit Drag Price”) and the Series A Preferred Unitholders holding Series A Preferred
Units constituting at least eighty percent (80%) of the then-outstanding Series A Preferred Units (it being understood that the eighty percent (80%) of Series A Preferred Units required to accept such offer shall exclude any Series A Preferred Units
held by APA, the Corporation, the Contributor, the General Partner and any of their respective Controlled Affiliates) accept such offer from the Partnership, the Corporation, APA or such Affiliate thereof, as applicable, then such Series A Preferred
Unitholders holding Series A Preferred Units constituting at least eighty percent (80%) of the then-outstanding Series A Preferred Units may, by providing written notice to the other Series A Preferred Unitholders (the “Series A Preferred
Unit Drag Notice”), elect to cause all Series A Preferred Unitholders to participate in such redemption, repurchase or acquisition of Series A Preferred Units by the Partnership for such Series A Preferred Unit Drag Price (the
“Series A Preferred Unit Drag Transaction”), it being understood that the Series A Preferred Units held by such Series A Preferred Unitholders shall be so redeemed, repurchased or acquired, as applicable, pro rata in
accordance with the Series A Preferred Unit Percentage Interests of the Series A Preferred Unitholders. Each such Series A Preferred Unit Drag Notice shall set forth (i) the number of Series A Preferred Units subject to the Series A Preferred
Unit Drag Transaction, (ii) the Series A Preferred Unit Drag Price for each Series A Preferred Unit subject to the Series A Preferred Unit Drag Transaction; (iii) the proposed date of consummation of such Series A Preferred Unit Drag
Transaction and (iv) copies of all proposed transaction documents relating to such Series A Preferred Unit Drag Transaction. Upon receipt of a Series A Preferred Unit Drag Notice delivered in accordance with this
Section 10.02(d), each Series A Preferred Unitholder shall take all actions as may be reasonably necessary to consummate such Series A Preferred Unit Drag Transaction by the date for consummation of such Series A Preferred
Unit Drag Transaction as set forth in the Series A Preferred Unit Drag Notice therefor. 

  
 59 

 Section 10.03 Restricted Units Legend. The Units have not
been registered under the Securities Act and, therefore, in addition to the other restrictions on Transfer contained in this Agreement, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is
then available. To the extent such Units have been certificated, each certificate evidencing Units and each certificate issued in exchange for or upon the Transfer of any Units (if such securities remain Units as defined herein after such Transfer)
shall be stamped or otherwise imprinted with a legend in substantially the following form: 
 “THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM
REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER SPECIFIED IN THE SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF ALTUS MIDSTREAM LP, AS MAY BE AMENDED
AND MODIFIED FROM TIME TO TIME, AND ALTUS MIDSTREAM LP RESERVES THE RIGHT TO REFUSE THE TRANSFER OF SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO ANY TRANSFER. A COPY OF SUCH CONDITIONS SHALL BE FURNISHED BY ALTUS
MIDSTREAM LP TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE.” 
 The Partnership shall imprint such legend on certificates (if any)
evidencing Units. The legend set forth above shall be removed from the certificates (if any) evidencing any units which cease to be Units in accordance with the definition thereof. 

Section 10.04 Transfer. Prior to Transferring any Units (other than (a) in connection with a Common
Redemption in accordance with Article XI or (b) an indirect Transfer), the Transferring holder of Units shall cause the prospective transferee to be bound by this Agreement and any other agreements executed by the holders of Units and
relating to such Units in the aggregate (collectively, the “Other Agreements”), and shall cause the prospective transferee to execute and deliver to the Partnership and the other holders of Units a Joinder (or other
counterpart to this Agreement acceptable to the General Partner) and counterparts of any applicable Other Agreements. Any Transfer or attempted Transfer of any Units in violation of any provision of this Agreement (including any prohibited indirect
Transfers) (i) shall be void and (ii) the Partnership shall not record such Transfer on its books or treat any purported transferee of such Units as the owner of such securities for any purpose. 

  
 60 

 Section 10.05 Assignee’s Rights. 

(a) The Transfer of a Limited Partner Interest in accordance with this Agreement shall be effective as of the date of its assignment (assuming
compliance with all of the conditions to such Transfer set forth herein), and such Transfer shall be shown on the books and records of the Partnership. Profits, Losses and other Partnership items shall be allocated between the transferor and the
Assignee according to Code Section 706, using any permissible method as determined in the reasonable discretion of the General Partner. Distributions made before the effective date of such Transfer shall be paid to the transferor, and
Distributions made after such date shall be paid to the Assignee. 
 (b) Unless and until an Assignee becomes a Limited Partner pursuant to
Article XII, the Assignee shall not be entitled to any of the rights granted to a Limited Partner hereunder or under applicable Law, other than the rights granted specifically to Assignees pursuant to this Agreement; provided,
however, that, without relieving the transferring Limited Partner from any such limitations or obligations as more fully described in Section 10.06, such Assignee shall be bound by any limitations and obligations of
a Limited Partner contained herein that a Limited Partner would be bound on account of the Assignee’s Limited Partner Interest (including the obligation to make Capital Contributions on account of such Limited Partner Interest). 

Section 10.06 Assignor’s Rights and Obligations. Any Limited Partner who shall Transfer any Limited
Partner Interest in a manner in accordance with this Agreement shall cease to be a Limited Partner with respect to such Units or other interest and shall no longer have any rights or privileges, or, except as set forth in this
Section 10.06, duties, liabilities or obligations, of a Limited Partner with respect to such Units or other interest (it being understood, however, that the applicable provisions of Section 7.01
and Section 7.04 shall continue to inure to such Person’s benefit), except that unless and until the Assignee (if not already a Limited Partner) is admitted as a Substituted Limited Partner in accordance with the
provisions of Article XII (the “Admission Date”), (a) such assigning Limited Partner shall retain all of the duties, liabilities and obligations of a Limited Partner with respect to such Units or other interest and
(b) the General Partner may, in its sole discretion, reinstate all or any portion of the rights and privileges of such Limited Partner with respect to such Units or other interest for any period of time prior to the Admission Date. Nothing
contained herein shall relieve any Limited Partner who Transfers any Units or other interest in the Partnership from any liability of such Limited Partner to the Partnership with respect to such Limited Partner Interest that may exist on the
Admission Date or that is otherwise specified in the Delaware Act and incorporated into this Agreement or for any liability to the Partnership or any other Person for any materially false statement made by such Limited Partner (in its capacity as
such) or for any present or future breaches of any representations, warranties or covenants by such Limited Partner (in its capacity as such) contained herein or in the other agreements with the Partnership. 

Section 10.07 Overriding Provisions. 

(a) Any Transfer in violation of this Article X shall be null and void ab initio, and the provisions of Sections 10.05
and 10.06 shall not apply to any such Transfers. For the avoidance of doubt, any Person to whom a Transfer is made or attempted in violation of this Article X shall not become a Limited Partner, shall not be entitled to vote on any
matters coming before the Limited Partners and shall not have any other rights in or with respect to any rights of a Limited Partner of the Partnership. The approval of any Transfer in any one or more instances shall not limit or waive the
requirement for such approval in any other or future instance. The General Partner shall promptly amend the Schedule of Limited Partners to reflect any Permitted Transfer pursuant to this Article X. 

  
 61 

 (b) Notwithstanding anything contained herein to the contrary (including, for the avoidance
of doubt, the provisions of Section 10.01, Article XI and Article XII), in no event shall any Limited Partner Transfer any Units to the extent such Transfer would: 

(i) result in the violation of the Securities Act, or any other applicable U.S. federal or state or
non-U.S. Laws; 
 (ii) subject the Partnership to registration as an investment company under the
Investment Company Act; 
 (iii) in the reasonable and good faith determination of the General Partner be a violation of or a default (or an
event that, with notice or the lapse of time or both, would constitute a default) under, or result in an acceleration of any indebtedness under, any promissory note, mortgage, loan agreement, indenture or similar instrument or agreement to which the
Partnership or the General Partner is a party; provided, that the payee or creditor to whom the Partnership or the General Partner owes such obligation is not an Affiliate of the Partnership or the General Partner; 

(iv) be a Transfer to a Person who is not legally competent or who has not achieved his or her majority age under applicable Law (excluding
trusts for the benefit of minors); and 
 (v) result in the Partnership having more than one hundred (100) partners, within the meaning
of Treasury Regulations Section 1.7704-1(h)(1) (determined pursuant to the rules of Treasury Regulations Section 1.7704-1(h)(3)). 

ARTICLE XI 
 REDEMPTION, CONVERSION
AND EXCHANGE RIGHTS; OTHER PROTECTIVE 
 PROVISIONS 

Section 11.01 Redemption Right of a Common Unitholder. 

(a) Subject to compliance with Section 6.01(e)(viii), each Common Unitholder (other than the Corporation) shall be
entitled to cause the Partnership to redeem (a “Common Redemption”) all or any portion of its Common Units (the “Common Redemption Right”) at any time. A Common Unitholder desiring to exercise its
Common Redemption Right (the “Common Redeemed Partner”) shall exercise such right by giving written notice (the “Common Redemption Notice”) to the Partnership with a copy to the Corporation (the date
of the delivery of such Common Redemption Notice, the “Common Redemption Notice Date”). The Common Redemption Notice shall specify the number of Common Units (the “Common Redeemed Units”) that the
Common Redeemed Partner intends to have the Partnership redeem. The Common Redemption shall be completed on the date that is three (3) Business Days following delivery of the applicable Common Redemption Notice, unless the Partnership elects to
make the redemption payment by means of a Cash Settlement, in which case the Common Redemption shall be completed as promptly as practicable following delivery of the applicable Common Redemption 

  
 62 

 
Notice, but in any event, no more than ten (10) Business Days after delivery of such Common Redemption Notice (unless and to the extent that the General Partner in its sole discretion agrees
in writing to waive such time periods) (the date of such completion, the “Common Redemption Date”); provided, that the Partnership, the Corporation and the Common Redeemed Partner may change the number of Common
Redeemed Units and/or the Common Redemption Date specified in such Common Redemption Notice to another number and/or date by mutual agreement signed in writing by each of them; provided, further, that a Common Redemption Notice may be
conditioned on the closing of an underwritten distribution of the shares of Class A Common Stock that may be issued in connection with such proposed Common Redemption. Unless the Common Redeemed Partner has timely delivered a Retraction Notice
as provided in Section 11.01(b) or has delayed a Common Redemption as provided in Section 11.01(c) or the Corporation has elected to effect a Direct Exchange as provided in
Section 11.03, on the Common Redemption Date (to be effective immediately prior to the close of business on the Common Redemption Date) (i) the Common Redeemed Partner shall transfer and surrender the Common Redeemed
Units to the Partnership and a corresponding number of shares of Class C Common Stock to the Corporation, in each case free and clear of all liens and encumbrances other than those arising under the Delaware Act or this Agreement; (ii) the
Partnership shall (x) cancel the Common Redeemed Units, (y) transfer to the Common Redeemed Partner the consideration to which the Common Redeemed Partner is entitled under Section 11.01(b) and (z) if the
Common Redeemed Units are certificated, issue to the Common Redeemed Partner a certificate for a number of Common Units equal to the difference (if any) between the number of Common Units evidenced by the certificate surrendered by the Common
Redeemed Partner pursuant to clause (i) of this Section 11.01(a) and the Common Redeemed Units and (iii) the Corporation shall cancel such shares of Class C Common Stock. 

(b) In exchange for its Common Redeemed Units, a Common Redeemed Partner shall be entitled to receive the Share Settlement or, at the
Partnership’s election, the Cash Settlement from the Partnership. Within one (1) Business Day of delivery of the Common Redemption Notice, the Partnership shall give written notice (the “Settlement Method Notice”)
to the Common Redeemed Partner (with a copy to the Corporation) of its intended settlement method; provided, that if the Partnership does not timely deliver a Settlement Method Notice, the Partnership shall be deemed to have elected the Share
Settlement method. The Common Redeemed Partner may retract its Common Redemption Notice by giving written notice (the “Retraction Notice”) to the Partnership (with a copy to the Corporation) at any time prior to 5:00 p.m.,
New York City time, on the Business Day after delivery of the Settlement Method Notice. The timely delivery of a Retraction Notice shall terminate all of the Common Redeemed Partner’s, the Partnership’s and the Corporation’s rights
and obligations under this Section 11.01 arising from the retracted Common Redemption Notice. 
 (c)
Notwithstanding anything to the contrary in Section 11.01(b), in the event the Partnership elects a Share Settlement in connection with a Common Redemption, a Common Redeemed Partner shall be entitled, at any time prior to
the consummation of a Common Redemption, to revoke its Common Redemption Notice or delay the consummation of a Common Redemption if any of the following conditions exists: (i) any registration statement pursuant to which the resale of the
Class A Common Stock to be registered for such Common Redeemed Partner at or immediately following the consummation of the Common Redemption shall have ceased to be effective pursuant to any action or inaction by the SEC or no such resale
registration 

  
 63 

 
statement has yet become effective; (ii) the Corporation shall have failed to cause any related prospectus to be supplemented by any required prospectus supplement necessary to effect such
Common Redemption; (iii) the Corporation shall have exercised its right to defer, delay or suspend the filing or effectiveness of a registration statement and such deferral, delay or suspension shall affect the ability of such Common Redeemed
Partner to have the resale of its Class A Common Stock registered at or immediately following the consummation of the Common Redemption; (iv) the Corporation shall have disclosed to such Common Redeemed Partner any material non-public information concerning the Corporation, the receipt of which results in such Common Redeemed Partner being prohibited or restricted from selling Class A Common Stock at or immediately following the
Common Redemption without disclosure of such information (and the Corporation does not permit disclosure); (v) any stop order relating to the registration statement pursuant to which the Class A Common Stock was to be registered by such Common
Redeemed Partner at or immediately following the Common Redemption shall have been issued by the SEC; (vi) there shall have occurred a material disruption in the securities markets generally or in the market or markets in which the Class A
Common Stock is then traded; (vii) there shall be in effect an injunction, a restraining order or a decree of any nature of any Governmental Entity that restrains or prohibits the Common Redemption; (viii) the Corporation shall have failed
to comply in all material respects with its obligations under the Registration Rights Agreement, and such failure shall have affected the ability of such Common Redeemed Partner to consummate the resale of Class A Common Stock to be received
upon such redemption pursuant to an effective registration statement; or (ix) the Common Redemption Date would occur three (3) Business Days or less prior to, or during, a Black-Out Period;
provided, further, that in no event shall the Common Redeemed Partner seeking to delay the consummation of such Common Redemption and relying on any of the matters contemplated in clauses (i) through (ix) above have
controlled or intentionally materially influenced any facts, circumstances or Persons in connection therewith (except in the good faith performance of his or her duties as an officer or director of the Corporation) in order to provide such Common
Redeemed Partner with a basis for such delay or revocation. If a Common Redeemed Partner delays the consummation of a Common Redemption pursuant to this Section 11.01(c), (A) the Common Redemption Date shall occur on the
third (3rd) Business Day following the date on which the conditions giving rise to such delay cease to exist (or such earlier day as the Corporation, the Partnership and such Common Redeemed Partner may agree in writing) and (B) notwithstanding
anything to the contrary in Section 11.01(b), the Common Redeemed Partner may retract its Common Redemption Notice by giving a Retraction Notice to the Partnership (with a copy to the Corporation) at any time prior to 5:00
p.m., New York City time, on the second (2nd) Business Day following the date on which the conditions giving rise to such delay cease to exist. 

(d) The amount of the Share Settlement or the Cash Settlement that a Common Redeemed Partner is entitled to receive under
Section 11.01(b) shall not be adjusted on account of any Distributions previously made with respect to the Common Redeemed Units or dividends previously paid with respect to Class A Common Stock; provided,
however, that if a Common Redeemed Partner causes the Partnership to redeem Common Redeemed Units and the Common Redemption Date occurs subsequent to the Record Date for any Distribution with respect to the Common Redeemed Units but prior to
payment of such Distribution, the Common Redeemed Partner shall be entitled to receive such Distribution with respect to the Common Redeemed Units on the date that it is made notwithstanding that the Common Redeemed Partner transferred and
surrendered the Common Redeemed Units to the Partnership prior to such date. 

  
 64 

 (e) In the event of a distribution (by dividend or otherwise) by the Corporation to all
holders of Class A Common Stock of evidences of its indebtedness, securities or other assets (including Equity Securities of the Corporation), but excluding any cash dividend or Distribution of any such assets received by the Corporation in
respect of its Units, then in exchange for its Common Redeemed Units, a Common Redeemed Partner shall be entitled to receive, in addition to the consideration set forth in Section 11.01(b), the amount of such security,
securities or other property that the Common Redeemed Partner would have received if such Common Redemption Right had been exercised and the Common Redemption Date had occurred immediately prior to the record date or effective time of any such
transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification,
recapitalization or otherwise) of such security, securities or other property that occurs after such record date or effective time. For the avoidance of doubt, subsequent to any such transaction, this Article XI shall apply mutatis
mutandis with respect to any such security, securities or other property received by holders of Class A Common Stock in such transaction. 

(f) If a Reclassification Event occurs, the General Partner or its successor, as the case may be, shall, as and to the extent necessary, amend
this Agreement in compliance with Section 16.03, and enter into any necessary supplementary or additional agreements, to ensure that, following the effective date of the Reclassification Event: (i) the rights of
holders of Common Units (other than the Corporation) set forth in this Section 11.01 provide that each Common Unit is redeemable for the same amount and same type of property, securities or cash (or combination thereof)
that one share of Class A Common Stock becomes exchangeable for or converted into as a result of the Reclassification Event (taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend,
reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the record date or effective time
for such Reclassification Event) and (ii) the Corporation or the successor to the Corporation, as applicable, is obligated to deliver such property, securities or cash upon such redemption. The Corporation shall not consummate or agree to
consummate any Reclassification Event unless the successor Person, if any, becomes obligated to comply with the obligations of the Corporation (in whatever capacity) under this Agreement. 

Section 11.02 Contribution of the Corporation. Subject to Section 11.03, in
connection with the exercise of a Common Redeemed Partner’s Common Redemption Rights under Section 11.01(a), the Corporation shall contribute to the Partnership the consideration the Common Redeemed Partner is entitled
to receive under Section 11.01(b). Unless the Common Redeemed Partner has timely delivered a Retraction Notice as provided in Section 11.01(b) or has delayed a Common Redemption as provided in
Section 11.01(c), or the Corporation has elected to effect a Direct Exchange as provided in Section 11.03, on the Common Redemption Date (to be effective immediately prior to the close of business
on the Common Redemption Date) (a) the Corporation shall make its Capital Contribution to the Partnership (in the form of the Share Settlement or the Cash Settlement, as applicable) required under this Section 11.02,
and (b) the Partnership shall issue to the Corporation a number of Common Units equal to the number of Common Redeemed Units surrendered by the Common Redeemed Partner. Notwithstanding any other provisions of this Agreement to the contrary, in
the event that the Partnership elects a Cash Settlement, the Corporation shall only be obligated to contribute to the Partnership an amount in respect of such 

  
 65 

 
Cash Settlement equal to the net proceeds (after deduction of any underwriters’ discounts or commissions and brokers’ fees or commissions) from the sale by the Corporation of a number
of shares of Class A Common Stock equal to the number of Common Redeemed Units to be redeemed with such Cash Settlement; provided, that the Corporation’s Capital Account shall be increased by an amount equal to any such discounts,
commissions and fees relating to such sale of shares of Class A Common Stock, and such amounts shall be borne by the Partnership, in each case in accordance with Section 6.05. 

Section 11.03 Exchange Right of the Corporation. 

(a) Notwithstanding anything to the contrary in this Article XI, the Corporation may, in its sole and absolute discretion, elect to
effect on the Common Redemption Date the exchange of Common Redeemed Units for the Share Settlement or Cash Settlement, at the Corporation’s option, through a direct exchange of such Common Redeemed Units and such consideration between the
Common Redeemed Partner and the Corporation (a “Direct Exchange”). Upon such Direct Exchange pursuant to this Section 11.03, the Corporation shall acquire the Common Redeemed Units and shall be
treated for all purposes of this Agreement as the owner of such Common Redeemed Units. 
 (b) The Corporation may, at any time prior to a
Common Redemption Date, deliver written notice (an “Exchange Election Notice”) to the Partnership and the Common Redeemed Partner setting forth its election to exercise its right to consummate a Direct Exchange;
provided, that such election does not prejudice the ability of the parties to consummate a Common Redemption or Direct Exchange on the Common Redemption Date. An Exchange Election Notice may be revoked by the Corporation at any time;
provided, that any such revocation does not prejudice the ability of the parties to consummate a Common Redemption on the Common Redemption Date. The right to consummate a Direct Exchange in all events shall be exercisable for all the Common
Redeemed Units that would have otherwise been subject to a Common Redemption. Except as otherwise provided by this Section 11.03, a Direct Exchange shall be consummated pursuant to the same timeframe and in the same manner
as the relevant Common Redemption would have been consummated if the Corporation had not delivered an Exchange Election Notice. 

Section 11.04 Redemption of Series A Preferred Units. 

(a) Redemption at the Partnership’s Election. The Partnership shall be entitled to redeem for cash (a
“Series A Redemption”) the Series A Preferred Units at any time in whole or, so long as Series A Preferred Units having an aggregate Series A Issue Price of at least $312,500,000 remain outstanding at the time of such
redemption and such redemption is for no fewer than 100,000 Series A Preferred Units, in part pro rata among the Series A Preferred Unitholders in accordance with their respective Series A Preferred Unit Percentage Interests (including any
Optional Exchanged Units prior to the applicable Optional Exchange Date). The Partnership shall exercise such right by giving written notice (the “Series A Redemption Notice”) to the Series A Preferred Unitholders (the date
of the delivery of such Series A Redemption Notice, the “Series A Redemption Notice Date”). The Series A Redemption Notice shall specify the number of Series A Preferred Units (the “Series A Redeemed
Units”) that the Partnership intends to redeem. The Series A Redemption shall be completed on the date that is three (3) Business 

  
 66 

 
Days following delivery of the applicable Series A Redemption Notice (the date of such completion, the “Series A Redemption Date”). On the Series A Redemption Date (to be
effective immediately prior to the close of business on the Series A Redemption Date) (i) the Series A Preferred Unitholders shall transfer and surrender their pro rata portion of the Series A Redeemed Units to the Partnership free and
clear of all liens and encumbrances other than those arising under the Delaware Act or this Agreement and (ii) the Partnership shall (A) cancel the Series A Redeemed Units and (B) transfer to the Series A Preferred Unitholders cash in
an amount equal to the Series A Redemption Price for each Series A Redeemed Unit. 
 (b) No Redemption at the Series A Preferred
Unitholder’s Election. Series A Preferred Unitholders shall not be entitled to cause the Partnership to redeem the Series A Preferred Units, except as set forth in Section 11.04(c) and
Section 11.04(d). 
 (c) Redemption upon a Series A Change of Control or Shin Oak Option Failure. Upon the
occurrence of a Series A Change of Control or the occurrence of a Shin Oak Option Failure, each Series A Preferred Unitholder (excluding any Series A Preferred Unitholder that is APA, the Corporation, the Contributor, the General Partner and any of
their respective Controlled Affiliates) shall have the right to require the Partnership to redeem for cash (the “COC or Shin Oak Option Failure Redemption Right”) (i) with respect to a Series A Change of Control, all or a
portion of such Series A Preferred Unitholder’s Series A Preferred Units and (ii) with respect to a Shin Oak Option Failure, a portion of such Series A Preferred Unitholder’s Series A Preferred Units in an amount not to exceed forty
percent (40%) of the Series A Preferred Units of such Series A Preferred Unitholder outstanding as of such time. The Partnership shall deliver to all Series A Preferred Unitholders a written notice (the “COC or Shin Oak Option Failure
Notice”) of the occurrence of any Series A Change of Control or the occurrence of a Shin Oak Option Failure, as applicable, (i) with respect to a Series A Change of Control other than a Series A Change of Control described in
clauses (c) and (f) of the definition thereof, at least twenty (20) Business Days prior to the consummation of such Series A Change of Control or, if it is impracticable for the Partnership to provide such twenty (20) Business
Days’ prior written notice, as soon as reasonably practicable in advance of consummating such Series A Change of Control, (ii) with respect to a Series A Change of Control described in either clause (c) or (f) of the
definition thereof, immediately upon the Partnership becoming aware of such Series A Change of Control and (iii) with respect to a Shin Oak Option Failure, immediately upon the occurrence of such Shin Oak Option Failure (or earlier, if
reasonably practicable), as applicable, except the failure of the Partnership to deliver such a COC or Shin Oak Option Failure Notice shall not prevent the Series A Preferred Unitholders from exercising their COC or Shin Oak Option Failure
Redemption Rights pursuant to the following sentence. Any Series A Preferred Unitholder intending to exercise its COC or Shin Oak Option Failure Redemption Right (a “COC or Shin Oak Option Failure Redeemed Partner”) shall
give written notice thereof (the “COC or Shin Oak Option Failure Redemption Notice”) to the Partnership, and if the Partnership delivered a COC or Shin Oak Option Failure Notice to such Series A Preferred Unitholder pursuant
to the preceding sentence, such Series A Preferred Unitholder must deliver its COC or Shin Oak Option Failure Redemption Notice within five (5) Business Days of receipt of such COC or Shin Oak Option Failure Notice. The COC or Shin Oak Option
Failure Redemption Notice shall, subject to the limitation in clause (ii) of the first sentence of this Section 11.04(c), specify the number of Series A Preferred Units (the “COC or Shin Oak Option
Failure Redeemed Units”) that the COC or Shin Oak Option Failure Redeemed Partner intends to cause the Partnership to redeem (the “COC or Shin Oak  

  
 67 

 
Option Failure Redemption”). The COC or Shin Oak Option Failure Redemption shall be completed promptly on the date on which such Series A Preferred Unitholder delivers its COC
or Shin Oak Option Failure Redemption Notice for such Series A Change of Control, as applicable, or the immediately following Business Day if such COC or Shin Oak Option Failure is not delivered on a Business Day (the date of such completion, the
“COC or Shin Oak Option Failure Redemption Date”). On the COC or Shin Oak Option Failure Redemption Date (to be effective immediately prior to the close of business on the COC or Shin Oak Option Failure Redemption
Date) (i) the COC or Shin Oak Option Failure Redeemed Partner shall transfer and surrender its COC or Shin Oak Option Failure Redeemed Units to the Partnership free and clear of all liens and encumbrances other than those arising under the
Delaware Act or this Agreement and (ii) the Partnership shall (x) cancel the COC or Shin Oak Option Failure Redeemed Units and (y) transfer to the COC or Shin Oak Option Failure Redeemed Partner cash in an amount equal to the Series A
Redemption Price for each COC or Shin Oak Option Failure Redeemed Unit. For avoidance of doubt, the Partnership may not effect a Series A Change of Control (other than a Series A Change of Control described in either clause (c) or
(f) of the definition thereof) unless it has complied with its obligations under this Section 11.04(c). 

(d) Certain Asset Dispositions. 

(i) In the event of any sale or series of sales of assets, other than a sale of any interests in any Existing Pipeline Joint Venture, resulting
in net proceeds to the Partnership or any of its Subsidiaries in excess of $150 million in the immediately preceding twelve (12) month period (such sale or the last sale in such series of sales, a “Material Asset
Disposition”), the Partnership shall either (i) offer to redeem, for cash, outstanding Series A Preferred Units (the “Asset Disposition Redemption”) with the aggregate amount of net proceeds from such Asset
Disposition (the “Asset Disposition Redemption Amount”) or (ii) use the Asset Disposition Redemption Amount to repay Indebtedness outstanding under the Credit Agreement (an “Asset Disposition
Repayment”); provided, that, if the use of the Asset Disposition Redemption Amount to redeem the Series A Preferred Units is not permitted under the Credit Agreement, the Partnership shall instead use the aggregate amount of such
net proceeds from such Asset Disposition (1) first, to repay any outstanding Indebtedness of the Partnership and its Subsidiaries and (2) second, for general partnership purposes consistent with the Series A Purpose. 

(ii) In the event of any sale or series of sales by the Partnership or any of its Subsidiaries of interests in any Existing Pipeline Joint
Venture (a “JV Asset Disposition”), the Partnership shall offer to redeem, for cash, outstanding Series A Preferred Units (the “JV Asset Disposition Redemption”) with the aggregate amount of proceeds
from such JV Asset Disposition (the “JV Asset Disposition Redemption Amount”). 
 (iii) In the case of a Material
Asset Disposition or a JV Asset Disposition, the Partnership shall deliver to all Series A Preferred Unitholders a written notice (the “Asset Disposition Notice”) of such Material Asset Disposition or JV Asset Disposition at
least twenty (20) Business Days prior to the consummation of such Material Asset Disposition or JV Asset Disposition. The Asset Disposition Notice will set forth (i) a description of the assets underlying the disposition and the associated
proceeds for each such asset, (ii) in the case of a Material Asset Disposition, whether the Partnership has elected Asset Disposition Repayment or Asset Disposition Redemption with the aggregate amount of net proceeds from such Material Asset

  
 68 

 
Disposition, and (iii) if applicable, the total amount of Series A Preferred Units that may be redeemed based on the Asset Disposition Redemption Amount or JV Asset Disposition Redemption
Amount, as applicable (the “Asset Disposition Redeemable Units”). If such notice indicates that the Partnership has elected Asset Disposition Redemption or JV Asset Disposition Redemption, any Series A Preferred Unitholder
intending to accept the Partnership’s offer to redeem (a “Asset Disposition Redeemed Partner”) shall give written notice (the “Asset Disposition Redemption Notice”) to the Partnership within ten
(10) Business Days of receipt of the Asset Disposition Notice. The Asset Disposition Redemption Notice shall specify the number of Series A Preferred Units held by such Asset Disposition Redeemed Partner that it intends to cause the Partnership
to redeem (the “Asset Disposition Redemption Election”). The number of Series A Preferred Units held by each Asset Disposition Redeemed Partner to be redeemed shall equal such Asset Disposition Redeemed Partner’s Asset
Disposition Redemption Election divided by the sum of all the Asset Disposition Redemption Elections received by the Partnership multiplied by the Asset Disposition Redeemable Units (the “Asset Disposition Redeemed Units”).
The Asset Disposition Repayment or Asset Disposition Redemption, as applicable, shall be completed no later than the first (1st) Business Day after the date of consummation of such Asset
Disposition (the date of such completion to which an Asset Disposition Redemption applies, the “Asset Disposition Redemption Date”). On the Asset Disposition Redemption Date (to be effective immediately prior to the close of
business on the Asset Disposition Redemption Date) (i) the Asset Disposition Redeemed Partner shall transfer and surrender their Asset Disposition Redeemed Units to the Partnership free and clear of all liens and encumbrances other than those
arising under the Delaware Act or this Agreement and (ii) the Partnership shall (A) cancel the Asset Disposition Redeemed Units and (B) transfer to the Asset Disposition Redeemed Partner cash in an amount equal to the Series A
Redemption Price for each Asset Disposition Redeemed Unit. For avoidance of doubt, the Partnership may not effect a Material Asset Disposition or JV Asset Disposition unless it has complied with its obligations under this
Section 11.04(d). 

  
 69 

 Section 11.05 Exchange of Series A Preferred Units for shares
of Class A Common Stock. 
 (a) Exchange at the Election of the Series A Preferred Unitholder. At any time on
or after the seventh (7th) anniversary of the Series A Issue Date, or at any time after a Series A Restricted Action has occurred, each Series A Preferred Unitholder shall be entitled to cause the Partnership to exchange (an “Optional
Exchange”) all or any portion of its Series A Preferred Units for the Series A Exchange Amount (the “Optional Exchange Right”); provided, that any Optional Exchange that would result in an aggregate
Series A Exchange Amount of less than $25 million must involve all of such Series A Preferred Unitholder’s Series A Preferred Units. A Series A Preferred Unitholder desiring to exercise its Optional Exchange Right (the “Optional
Exchanging Partner”) shall exercise such right by giving written notice (the “Optional Exchange Notice”) to the Partnership with a copy to the Corporation (the date of the delivery of such Optional Exchange
Notice, the “Optional Exchange Notice Date”). The Optional Exchange Notice shall specify the number of Series A Preferred Units (the “Optional Exchanged Units”) that the Optional Exchanging Partner
intends to have the Partnership exchange for the Series A Exchange Amount. The Optional Exchange shall be completed on the date that is three (3) Business Days following delivery of the applicable Optional Exchange Notice, unless the
Partnership elects to make the redemption payment by means of a Series A Cash Settlement, in which case the Optional Exchange shall be completed as promptly as practicable following delivery of the applicable Optional Exchange Notice, but in any
event, no more than five (5) Business Days after delivery of such Optional Exchange Notice (unless and to the extent that the General Partner in its sole discretion agrees in writing to waive such time periods) (the date of such completion, the
“Optional Exchange Date”); provided, that the Partnership, the Corporation and the Optional Exchanging Partner may change the number of Optional Exchanged Units and/or the Optional Exchange Date specified in such
Optional Exchange Notice to another number and/or date by mutual agreement signed in writing by each of them; provided, further, that an Optional Exchange Notice may be conditioned on the closing of an underwritten distribution of the
shares of Class A Common Stock that may be issued in connection with such proposed Optional Exchange. Unless the Optional Exchanging Partner has timely delivered an Optional Exchange Retraction Notice as provided in
Section 11.05(b) or has delayed an Optional Exchange as provided in Section 11.05(c), on the Optional Exchange Date (to be effective immediately prior to the close of business on the Optional
Exchange Date) (i) the Optional Exchanging Partner shall transfer and surrender the Optional Exchanged Units to the Partnership, free and clear of all liens and encumbrances other than those arising under the Delaware Act or this Agreement and
(ii) the Partnership shall (A) cancel the Optional Exchanged Units, (B) transfer to the Optional Exchanging Partner the consideration to which the Optional Exchanging Partner is entitled under
Section 11.05(b) and (C) if the Optional Exchanged Units are certificated, issue to the Optional Exchanging Partner a certificate for a number of Series A Preferred Units equal to the difference (if any) between the
number of Series A Preferred Units evidenced by the certificate surrendered by the Optional Exchanging Partner pursuant to clause (i) of this Section 11.05(a) and the Optional Exchanged Units. 

(b) In exchange for each Optional Exchanged Unit, an Optional Exchanging Partner shall be entitled to receive the Series A Exchange Amount or,
at the Partnership’s election, payment of the Series A Cash Settlement from the Partnership. Within one (1) Business Day of delivery of the Optional Exchange Notice, the Partnership shall give written notice (the “Optional
Exchange Settlement Method Notice”) to the Optional Exchanging Partner (with a copy to the Corporation) of its intended settlement method; provided, that if the Partnership does not timely

  
 70 

 
deliver an Optional Exchange Settlement Method Notice, the Partnership shall be deemed to have elected the Series A Exchange Amount settlement method. The Optional Exchanging Partner may retract
its Optional Exchange Notice by giving written notice (the “Optional Exchange Retraction Notice”) to the Partnership (with a copy to the Corporation) at any time prior to 5:00 p.m., New York City time, on the Business Day
after delivery of the Optional Exchange Settlement Method Notice. The timely delivery of an Optional Exchange Retraction Notice shall terminate all of the Optional Exchanging Partner’s, the Partnership’s and the Corporation’s rights
and obligations under this Section 11.05 arising from the retracted Optional Exchange Notice. 
 (c)
Notwithstanding anything to the contrary in Section 11.05(b), in the event the Partnership elects to settle an Optional Exchange with the Series A Exchange Amount, an Optional Exchanging Partner shall be entitled, at any
time prior to the consummation of an Optional Exchange, to revoke its Optional Exchange Notice or delay the consummation of an Optional Exchange if any of the following conditions exists: (i) any registration statement pursuant to which the
resale of the Class A Common Stock to be registered for such Optional Exchanging Partner at or immediately following the consummation of the Optional Exchange shall have ceased to be effective pursuant to any action or inaction by the SEC or no
such resale registration statement has yet become effective; (ii) the Corporation shall have failed to cause any related prospectus to be supplemented by any required prospectus supplement necessary to effect such Optional Exchange;
(iii) the Corporation shall have exercised its right to defer, delay or suspend the filing or effectiveness of a registration statement and such deferral, delay or suspension shall affect the ability of such Optional Exchanging Partner to have
the resale of its Class A Common Stock registered at or immediately following the consummation of the Optional Exchange; (iv) the Corporation shall have disclosed to such Optional Exchanging Partner any material non-public information concerning the Corporation, the receipt of which results in such Optional Exchanging Partner being prohibited or restricted from selling Class A Common Stock at or immediately following
the Optional Exchange without disclosure of such information (and the Corporation does not permit disclosure); (v) any stop order relating to the registration statement pursuant to which the Class A Common Stock was to be registered by such
Optional Exchanging Partner at or immediately following the Optional Exchange shall have been issued by the SEC; (vi) there shall have occurred a material disruption in the securities markets generally or in the market or markets in which the
Class A Common Stock is then traded; (vii) there shall be in effect an injunction, a restraining order or a decree of any nature of any Governmental Entity that restrains or prohibits the Optional Exchange; (viii) the Corporation
shall have failed to comply in all material respects with its obligations under the Series A Registration Rights Agreement, and such failure shall have affected the ability of such Optional Exchanging Partner to consummate the resale of Class A
Common Stock to be received upon such redemption pursuant to an effective registration statement; or (ix) the Optional Exchange Date would occur three (3) Business Days or less prior to, or during, a
Black-Out Period; provided, further, that in no event shall the Optional Exchanging Partner seeking to delay the consummation of such Optional Exchange and relying on any of the matters
contemplated in clauses (i) through (ix) above have controlled or intentionally materially influenced any facts, circumstances, or Persons in connection therewith (except in the good faith performance of his or her duties as an
officer or director of the Corporation) in order to provide such Optional Exchanging Partner with a basis for such delay or revocation. If an Optional Exchanging Partner delays the consummation of an Optional Exchange pursuant to this
Section 11.05, (A) the Optional Exchange Date shall occur on the third (3rd) Business Day following the date on which the conditions giving rise to such delay cease to exist (or such earlier day as the

  
 71 

 
Corporation, the Partnership and such Optional Exchanging Partner may agree in writing) and (B) notwithstanding anything to the contrary in Section 11.05(b), the
Optional Exchanging Partner may retract its Optional Exchange Notice by giving an Optional Exchange Retraction Notice to the Partnership (with a copy to the Corporation) at any time prior to 5:00 p.m., New York City time, on the second (2nd) Business Day following the date on which the conditions giving rise to such delay cease to exist. 

(d) Exchange Upon Liquidation of the Partnership. In the event of a liquidation or dissolution of the Partnership in accordance with
Article XIV, each Series A Preferred Unitholder shall be entitled to cause the Partnership to exchange (a “Liquidation Exchange”) all or any portion of its Series A Preferred Units for the Series A Exchange Amount (the
“Liquidation Exchange Right”) as described in this Section 11.05(d). A Series A Preferred Unitholder desiring to exercise its Liquidation Exchange Right (the “Liquidation Exchanging
Partner”) shall exercise such right by giving written notice (the “Liquidation Exchange Notice”) to the Partnership with a copy to the Corporation within five (5) Business Days of receipt of the notice of
liquidation provided to the Series A Preferred Unitholders by the liquidators in accordance with Section 14.02(b), it being understood that if a Series A Preferred Unitholder does not timely deliver a Liquidation Exchange
Notice for any Series A Preferred Units in accordance with this Section 11.05(d), then the outstanding Series A Preferred Units held by such Series A Preferred Unitholder shall instead be governed by Article XIV. The
Liquidation Exchange Notice shall specify the number of Series A Preferred Units (the “Liquidation Exchanged Units”) that the Liquidation Exchanging Partner intends to have the Partnership exchange for the Series A Exchange
Amount. The Liquidation Exchange shall be completed on the date that is three (3) Business Days following the date of delivery of the applicable Liquidation Exchange Notice or the Business Day prior to the Liquidation Date, whichever is earlier
(the “Liquidation Exchange Date”). On the Liquidation Exchange Date (to be effective immediately prior to the close of business on the Liquidation Exchange Date), (i) the Liquidation Exchanging Partner shall transfer and
surrender the Liquidation Exchanged Units to the Partnership free and clear of all liens and encumbrances other than those arising under the Delaware Act or this Agreement and (ii) the Partnership shall (A) cancel the Liquidation Exchanged
Units, (B) transfer to the Liquidation Exchanging Partner a number of shares of Class A Common Stock having an aggregate Series A Reference Price equal to the aggregate Series A Redemption Price attributable to the aggregate Liquidation
Exchanged Units and (C) if the Liquidation Exchanged Units are certificated, issue to the Liquidation Exchanging Partner a certificate for a number of Series A Preferred Units equal to the difference (if any) between the number of Series A
Preferred Units evidenced by the certificate surrendered by the Liquidation Exchanging Partner pursuant to clause (i) of this Section 11.05(d) and the Liquidation Exchanged Units. 

(e) Issuance Limitation. Notwithstanding anything to the contrary in this Agreement, if the Corporation has not obtained Requisite
Stockholder Approval, then the Corporation shall not issue, upon exchange of Series A Preferred Units in accordance with Section 11.05(a) and Section 11.05(d), a number of shares of Class A
Common Stock that would exceed nineteen and one half percent (19.5%) of (i) the shares of Class A Common Stock outstanding on the Series A Issue Date or (ii) the voting power of outstanding Equity Securities of the Corporation on the
Series A Issue Date as calculated in accordance with Stock Exchange regulations (the “Issuable Maximum”). If the Corporation has not obtained Requisite Stockholder Approval upon exchange of any Series A Preferred Units
subject to the foregoing limitation, then the applicable Series A 

  
 72 

 
Preferred Unitholder shall be entitled to receive upon such exchange a number of shares of Class A Common Stock equal to the lesser of (A) the Series A Exchange Amount with respect to
such Series A Preferred Units and (B) such Series A Preferred Unitholder’s pro rata portion of the Issuable Maximum. 
 (f)
Certain Adjustments. 
 (i) In the event of a Distribution (by dividend or otherwise) by the Corporation to all holders of
Class A Common Stock of evidences of its indebtedness, securities or other assets (including Equity Securities of the Corporation), but excluding any cash dividend or Distribution of any such assets received by the Corporation in respect of its
Units, then the Series A Exchange Amount shall be adjusted to include the amount of such security, securities or other property that the Optional Exchanging Partner or Liquidation Exchanging Partner would have received if such Optional Exchange
Right or Liquidation Exchange Right had been exercised and the Optional Exchange Date or Liquidation Exchange Date had occurred immediately prior to the record date or effective time of any such transaction, taking into account any adjustment as a
result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or
other property that occurs after such record date or effective time. For the avoidance of doubt, subsequent to any such transaction, this Article XI shall apply mutatis mutandis with respect to any such security, securities or other
property received by holders of Class A Common Stock in such transaction. 
 (ii) If a Reclassification Event occurs, the General
Partner or its successor, as the case may be, shall, as and to the extent necessary, amend this Agreement in compliance with Section 16.03, and enter into any necessary supplementary or additional agreements, to ensure
that, following the effective date of the Reclassification Event: (A) each Optional Exchanged Unit and Liquidation Exchanged Unit is exchangeable for the same amount and same type of property, securities or cash (or combination thereof) that
the Series A Exchange Amount becomes exchangeable for or converted into as a result of the Reclassification Event (taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification,
reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the record date or effective time for such
Reclassification Event) and (B) the Corporation or the successor to the Corporation, as applicable, is obligated to deliver such property, securities or cash upon such exchange. The Corporation shall not consummate or agree to consummate any
Reclassification Event unless the successor Person, if any, becomes obligated to comply with the obligations of the Corporation (in whatever capacity) under this Agreement. 

(g) Actions to be Taken by the Corporation. 

(i) In connection with the exercise of an Optional Exchanging Partner’s Optional Exchange Rights under
Section 11.05(a), the Corporation shall contribute to the Partnership the consideration the Optional Exchanging Partner is entitled to receive under Section 11.05(b). Unless the Optional Exchanging
Partner has timely delivered an Optional Exchange Retraction Notice as provided in Section 11.05(b) or has delayed an Optional Exchange as provided in Section 11.05(c), on the Optional Exchange
Date (to be effective immediately prior to 

  
 73 

 
the close of business on the Optional Exchange Date) (A) the Corporation shall make its Capital Contribution to the Partnership (in the form of the Series A Exchange Amount or the Series A
Cash Settlement, as applicable) required under this Section 11.05(g), and (B) the Partnership shall issue to the Corporation a number of Common Units equal to the number of shares of Class A Common Stock issued to
the Optional Exchanging Partner. Notwithstanding any other provisions of this Agreement to the contrary, in the event that the Partnership elects a Series A Cash Settlement, the Corporation shall only be obligated to contribute to the Partnership an
amount in respect of such Series A Cash Settlement equal to the net proceeds (after deduction of any underwriters’ discounts or commissions and brokers’ fees or commissions) from the sale by the Corporation of a number of shares of
Class A Common Stock equal to the number of Optional Exchanged Units to be redeemed with such Series A Cash Settlement; provided, that the Corporation’s Capital Account shall be increased by an amount equal to any such discounts,
commissions and fees relating to such sale of shares of Class A Common Stock, and such amounts shall be borne by the Partnership, in each case in accordance with Section 6.05. 

(ii) In connection with the exercise of a Liquidation Exchanging Partner’s Liquidation Exchange Rights under
Section 11.05(d), the Corporation shall contribute to the Partnership the consideration the Liquidation Exchanging Partner is entitled to receive under Section 11.05(d). On the Liquidation Exchange
Date (to be effective immediately prior to the close of business on the Liquidation Exchange Date) (A) the Corporation shall make a Capital Contribution to the Partnership in an amount equal to the aggregate Series A Redemption Price provided
for in clause (B) of Section 11.05(d), and (B) the Partnership shall issue to the Corporation a number of Common Units equal to the number of shares of Class A Common Stock issued to the Liquidation
Exchanging Partner. 
 Section 11.06 Reservation of Shares of Class A Common Stock; Listing;
Registration Rights; Certificate of the Corporation. 
 (a) Reservation of Shares. 

(i) At all times the Corporation shall reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the
purpose of issuance upon a Common Redemption or Direct Exchange, such number of shares of Class A Common Stock as shall be issuable upon any Common Redemption or Direct Exchange pursuant to Share Settlements; provided, that nothing
contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such Common Redemption or Direct Exchange by delivery of purchased Class A Common Stock (which may or may not be held in the
treasury of the Corporation) or the delivery of cash pursuant to a Cash Settlement. 
 (ii) At all times the Corporation shall reserve and
keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon Optional Exchange or Liquidation Exchange, a number of shares of Class A Common Stock equal to the Series A Required Minimum;
provided, that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such Optional Exchange or Liquidation Exchange by delivery of purchased Class A Common Stock (which
may or may not be held in the treasury of the Corporation). 

  
 74 

 (b) Listing of Shares. The Corporation shall use its commercially reasonable efforts
to list the Class A Common Stock required to be delivered upon any Common Redemption, Direct Exchange, Optional Exchange or Liquidation Exchange prior to such delivery upon each National Securities Exchange upon which the outstanding shares of
Class A Common Stock are listed at the time of such Common Redemption, Direct Exchange, Optional Exchange or Liquidation Exchange (it being understood that any such shares may be subject to transfer restrictions under applicable securities
Laws). 
 (c) Registration Rights. 

(i) Following the fifth (5th) anniversary of the Series A Issue Date and upon request of Series A Preferred Unitholders representing the Series
A Required Voting Percentage then outstanding, the Partnership shall file a registration statement under the Securities Act to permit the public resale of all of the then-outstanding Series A Preferred Units from time to time as permitted under the
Securities Act (or any successor or similar provision adopted by the SEC then in effect) and shall use its commercially reasonable best efforts to cause such registration statement to be declared effective within six (6) months after such
request. A registration statement filed pursuant to this Section 11.06(c)(i) shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Series A Preferred
Unitholders. The Partnership shall use its commercially reasonable best efforts to cause a registration statement filed pursuant to this Section 11.06(c)(i) 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 Series A Preferred Units until all such Series A Preferred Units have been
sold or ceased to be outstanding (the “Effectiveness Period”). 
 (ii) If the Partnership fails to meet the timeline
for filing a registration statement as specified in Section 11.06(c)(i), or the registration statement is declared effective but (A) the registration statement shall thereafter be withdrawn by the Partnership or shall
become subject to an effective stop order issued pursuant to Section 8(d) of the Securities Act suspending the effectiveness of such registration statement without being succeeded by an additional registration statement filed and declared
effective within fifteen (15) Business Days, or (B) except as addressed by the foregoing clause (A), the registration statement fails to be available for the resale by the Series A Preferred Unitholders of all the Series A Preferred
Units required to be included therein during the Effectiveness Period (each such event, a “Registration Default”), then each Series A Preferred Unitholder shall be entitled to a payment (with respect to each of the Series A
Preferred Unitholder’s pro rata share of the Series A Preferred Units as liquidated damages and not as a penalty), (A) for the first ninety (90) days following the occurrence of such Registration Default, an amount equal to 0.25% of
the aggregate Series A Issue Price of the then-outstanding Series A Preferred Units on the ninetieth (90th) day of such period (the “Liquidated Damages Multiplier”), which shall accrue daily, and (B) for each non-overlapping 90-day period beginning on the ninety first (91st) day thereafter, an amount equal to the amount set forth in clause (B) plus an additional
0.25% of the Liquidated Damages Multiplier for each subsequent ninety (90) days (i.e., 0.50% for 91-180 days, 0.75% for 181-270 days, 1.00% for 271-360 days, etc.), which shall accrue daily, up to a maximum amount equal to 2.50% of the Liquidated Damages Multiplier per non-overlapping ninety (90) day
period, until such time as such Registration Default is cured or there are no longer any Series A Preferred Units outstanding. 

  
 75 

 (iii) The Partnership covenants that it shall take such action as any Series A Preferred
Unitholder may reasonably request, all to the extent required from time to time to enable such Series A Preferred Unitholder to sell the Series A Preferred Units held by such Series A Preferred Unitholder 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 SEC), including, without limitation, at the sole expense of the Partnership, (A) issuing
such directions to any transfer agent, registrar or depositary, as applicable, (B) delivering such opinions to the transfer agent, registrar or depositary as are customary for the transaction of this type and are reasonably requested by the
same and (C) taking or causing to be taken such other actions as are reasonably necessary (in each case on a timely basis) in order to cause any legends, notations or similar designations restricting transferability of the Series A Preferred
Units held by such Series A Preferred Unitholder to be removed and to rescind any transfer restrictions with respect to such Series A Preferred Units; provided, however, that such Series A Preferred Unitholder shall deliver to the
Partnership, in form and substance reasonably satisfactory to the Partnership, representation letters regarding such Series A Preferred Unitholder’s compliance with Rule 144 or Rule 144A, as may be applicable. Upon the request of any Series A
Preferred Unitholder, the Partnership shall deliver to such Series A Preferred Unitholder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

(iv) The Corporation shall deliver Class A Common Stock that has been registered under the Securities Act with respect to any Common
Redemption or Direct Exchange to the extent a registration statement is effective and available for such shares. 
 (d) Certificate of
the Corporation. The Corporation covenants that all Class A Common Stock issued upon a Common Redemption, Direct Exchange, Optional Exchange or Liquidation Exchange will, upon issuance, be validly issued, fully paid and non-assessable. The provisions of this Article XI shall be interpreted and applied in a manner consistent with the corresponding provisions of the Corporation’s certificate of incorporation. 

Section 11.07 Effect of Exercise of Redemption or Exchange Right. This Agreement shall continue
notwithstanding the consummation of a Common Redemption, Direct Exchange, COC or Shin Oak Option Failure Redemption, Asset Disposition Redemption, Series A Redemption or Optional Exchange and all governance or other rights set forth herein shall be
exercised by the remaining Partners. No Common Redemption, Direct Exchange, COC or Shin Oak Option Failure Redemption, Asset Disposition Redemption, Series A Redemption or Optional Exchange shall relieve any Partner of any prior breach of this
Agreement. 
 Section 11.08 Tax Treatment. Unless otherwise required by applicable Law, the parties hereto
acknowledge and agree that any Common Redemption, Direct Exchange, Optional Exchange or Liquidation Exchange, as the case may be, shall be treated as a direct exchange between the Corporation and the applicable Limited Partner and, if the
Corporation is deemed to receive Series A Preferred Units in any such direct exchange, such Units shall be treated as converted into Common Units immediately following such direct exchange, for U.S. federal (and applicable state and local) income
tax purposes. The issuance of shares of Class A Common Stock or other securities upon a Common Redemption, Direct Exchange or Optional Exchange shall be made without charge to the applicable Limited Partner for any stamp or other similar tax in
respect of such issuance. 

  
 76 

 Section 11.09 No Restrictions. There are no limitations on
the Common Redemption Right of any Common Redeemed Partner, and this Agreement does not contractually restrict the ability of any Limited Partner or the Affiliates of such Limited Partner to transfer its or their Class A Common Stock. 

ARTICLE XII 
 ADMISSION OF LIMITED
PARTNERS 
 Section 12.01 Substituted Limited Partners. Subject to the provisions of Article
X, in connection with the Permitted Transfer of a Limited Partner Interest hereunder, the transferee shall become a substituted Limited Partner (“Substituted Limited Partner”) on the effective date of such Transfer, which
effective date shall not be earlier than the date of compliance with the conditions to such Transfer, and such admission shall be shown on the books and records of the Partnership. 

Section 12.02 Additional Limited Partners. Subject to the provisions of Article III and
Article X, any Person may be admitted to the Partnership as an additional Limited Partner (any such Person, an “Additional Limited Partner”) only upon furnishing to the General Partner (a) a Joinder (or other
counterpart to this Agreement acceptable to the General Partner) and counterparts of any applicable Other Agreements and (b) such other documents or instruments as may be reasonably necessary or appropriate to effect such Person’s
admission as a Limited Partner (including entering into such documents as the General Partner may deem appropriate in its reasonable discretion). Such admission shall become effective on the date on which the General Partner determines in its
reasonable discretion that such conditions have been satisfied and when any such admission is shown on the books and records of the Partnership. 

ARTICLE XIII 
 WITHDRAWAL AND
RESIGNATION; TERMINATION OF RIGHTS 
 Section 13.01 Withdrawal and Resignation of Limited Partners.
No Limited Partner shall have the power or right to withdraw or otherwise resign as a Limited Partner from the Partnership prior to the dissolution and winding up of the Partnership pursuant to Article XIV. Any Limited Partner, however, that
attempts to withdraw or otherwise resign as a Limited Partner from the Partnership without the prior written consent of the General Partner upon or following the dissolution and winding up of the Partnership pursuant to Article XIV, but prior
to such Limited Partner receiving the full amount of Distributions from the Partnership to which such Limited Partner is entitled pursuant to Article XIV, shall be liable to the Partnership for all damages (including all lost profits and
special, indirect and consequential damages) directly or indirectly caused by the withdrawal or resignation of such Partner. Upon a Transfer of all of a Limited Partner’s Units in a Transfer permitted by this Agreement, subject to the
provisions of Section 10.06, such Limited Partner shall cease to be a Partner. 

  
 77 

 ARTICLE XIV 

DISSOLUTION AND LIQUIDATION 

Section 14.01 Dissolution. The Partnership shall not be dissolved by the admission of Additional Limited
Partners or Substituted Limited Partners or the attempted withdrawal or resignation of a Partner. Subject to Section 6.01(e) and Section 11.05(d), the Partnership shall dissolve, and its affairs
shall be wound up, upon: 
 (a) the unanimous decision of the General Partner together with all the Common Unitholders to dissolve the
Partnership; 
 (b) a dissolution of the Partnership under Section 17-801(4) of the Delaware
Act; or 
 (c) the entry of a decree of judicial dissolution of the Partnership under
Section 17-802 of the Delaware Act. 
 Except as otherwise set forth in this Article XIV, the
Partnership is intended to have perpetual existence. An Event of Withdrawal shall not cause a dissolution of the Partnership and the Partnership shall continue in existence subject to the terms and conditions of this Agreement. 

Section 14.02 Liquidation and Termination. On dissolution of the Partnership, the General Partner shall act
as liquidator or may appoint one or more Persons as liquidator. The liquidators shall proceed diligently to wind up the affairs of the Partnership and make final Distributions as provided herein and in the Delaware Act. The costs of liquidation
shall be borne as a Partnership expense. Until final Distribution, the liquidators shall continue to operate the Partnership properties with all of the power and authority of the General Partner. The steps to be accomplished by the liquidators are
as follows: 
 (a) as promptly as possible after dissolution and again after final liquidation, the liquidators shall cause a proper
accounting to be made by a recognized firm of certified public accountants of the Partnership’s assets, liabilities and operations through the last day of the calendar month in which the dissolution occurs or the final liquidation is completed,
as applicable; 
 (b) the liquidators shall cause notice of liquidation to be mailed to each known creditor of and claimant against the
Partnership and to each Series A Preferred Unitholder; 
 (c) the liquidators shall pay, satisfy or discharge from Partnership funds, or
otherwise make adequate provisions for payment and discharge thereof (including the establishment of a cash fund for contingent liabilities in such amount and for such term as the liquidators may reasonably determine): first, all expenses incurred
in liquidation; and second, all of the debts, liabilities and obligations of the Partnership; 

  
 78 

 (d) all remaining assets of the Partnership shall be distributed to the Series A Preferred
Unitholders and Common Unitholders, as applicable, by the end of the Taxable Year during which the liquidation of the Partnership occurs (or, if later, by ninety (90) days after the date of the liquidation) as follows: 

(i) first, 100% to the Series A Preferred Unitholders pro rata in accordance with their respective Series A Preferred Unit Percentage
Interests in redemption of any outstanding Series A Preferred Units in an amount per Series A Preferred Unit equal to the Series A Redemption Price for such Series A Preferred Unit (it being understood that any distributions under this
Section 14.02 shall be in cash and not a distribution in-kind as provided by Section 14.03); and 

(ii) the remainder, if any, 100% to the Common Unitholders pro rata in accordance with their respective Common Unit Percentage
Interests. 
 The distribution of cash and/or property to the Partners in accordance with the provisions of this
Section 14.02 and Section 14.03 below constitutes a complete return to the Partners of their Capital Contributions, a complete distribution to the Partners of their interest in the Partnership and
all the Partnership’s property and constitutes a compromise to which all Partners have consented within the meaning of the Delaware Act. To the extent that a Partner returns funds to the Partnership, it has no claim against any other Partner
for those funds. 
 Section 14.03 Deferment; Distribution in Kind. Notwithstanding the provisions of
Section 14.02, but subject to the order of priorities set forth therein, if upon dissolution of the Partnership the liquidators determine that an immediate sale of part or all of the Partnership’s assets would be
impractical or would cause undue loss (or would otherwise not be beneficial) to the Partners, the liquidators may, in their sole discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy Partnership
liabilities (other than loans to the Partnership by Partners, but including any liabilities in respect of the Series A Preferred Units) and reserves. Subject to the order of priorities set forth in Section 14.02, the
liquidators may, in their sole discretion, distribute to the Partners, in lieu of cash (other than any Series A Preferred Unitholder unless the Series A Preferred Unitholders representing the Series A Required Voting Percentage consent otherwise),
either (a) all or any portion of such remaining Partnership assets in-kind in accordance with the provisions of Section 14.02(c), (b) as tenants in common and in accordance with
the provisions of Section 14.02(c), undivided interests in all or any portion of such Partnership assets or (c) a combination of the foregoing. Any such Distributions in kind shall be subject to (i) such
conditions relating to the disposition and management of such assets as the liquidators deem reasonable and equitable and (ii) the terms and conditions of any agreements governing such assets (or the operation thereof or the holders thereof) at
such time. Any Partnership assets distributed in kind will first be written up or down to their Fair Market Value, thus creating Profit or Loss (if any), which shall be allocated in accordance with Article V. The liquidators shall determine
the Fair Market Value of any property distributed in accordance with the valuation procedures set forth in Article XV. 

Section 14.04 Cancellation of Certificate. On completion of the Distribution of Partnership assets as
provided herein, the Partnership is terminated (and the Partnership shall not be terminated prior to such time), and the General Partner (or such other Person or Persons as the Delaware Act may require or permit) shall file a certificate of
cancellation with the Secretary of State of the State of Delaware, cancel any other filings made pursuant to this Agreement that are or should be canceled and take such other actions as may be necessary to terminate the Partnership. The Partnership
shall be deemed to continue in existence for all purposes of this Agreement until it is terminated pursuant to this Section 14.04. 

  
 79 

 Section 14.05 Reasonable Time for Winding Up. A reasonable
time shall be allowed for the orderly winding up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Sections 14.02 and 14.03 in order to minimize any losses otherwise attendant upon such
winding up. 
 Section 14.06 Return of Capital. The liquidators shall not be personally liable for the
return of Capital Contributions or any portion thereof to the Partners (it being understood that any such return shall be made solely from Partnership assets). 

ARTICLE XV 
 VALUATION 

Section 15.01 Determination. “Fair Market Value” of a specific Partnership asset will
mean the amount which the Partnership would receive in an all-cash sale of such asset in an arms-length transaction with a willing unaffiliated third party, with neither party having any compulsion to buy or
sell, consummated on the day immediately preceding the date on which the event occurred which necessitated the determination of the Fair Market Value (and after giving effect to any transfer taxes payable in connection with such sale), as such
amount is determined by the General Partner (or, if pursuant to Section 14.02, the liquidators) in its good faith judgment using all factors, information and data it deems to be pertinent. 

Section 15.02 Dispute Resolution. If any Limited Partner or Limited Partners dispute the accuracy of any
determination of Fair Market Value in accordance with Section 15.01, and the General Partner and such Limited Partner(s) are unable to agree on the determination of the Fair Market Value of any asset of the Partnership, the
General Partner and such Limited Partner(s) shall each select a nationally recognized investment banking firm experienced in valuing securities of closely-held companies such as the Partnership in the Partnership’s industry (the
“Appraisers”), who shall each determine the Fair Market Value of the asset or the Partnership (as applicable) in accordance with the provisions of Section 15.01. The Appraisers shall be instructed to
give written notice of their determination of the Fair Market Value of the asset or the Partnership (as applicable) within thirty (30) days of their appointment as Appraisers. If Fair Market Value as determined by an Appraiser is higher than
Fair Market Value as determined by the other Appraiser by ten percent (10%) or more, and the General Partner and such Limited Partner(s) do not otherwise agree on a Fair Market Value, the original Appraisers shall designate a third Appraiser meeting
the same criteria used to select the original two, and the Fair Market Value shall be the average of the Fair Market Values determined by all three Appraisers, unless the General Partner and such Limited Partner(s) otherwise agree on a Fair Market
Value. If Fair Market Value as determined by an Appraiser is within ten percent (10%) of the Fair Market Value as determined by the other Appraiser (but not identical), and the General Partner and such Limited Partner(s) do not otherwise agree on a
Fair Market Value, the General Partner shall select the Fair Market Value of one of the Appraisers. The fees and expenses of the Appraisers shall be borne by the Partnership.

(i) execute, swear to, acknowledge, deliver, file and record in the appropriate public offices (A) this Agreement, all certificates and

 (b) The foregoing power of attorney is
irrevocable and coupled with an interest, and shall survive the death, disability, incapacity, dissolution, bankruptcy, insolvency or termination of any Limited Partner who is an individual and the transfer of all or any portion of his, her or its
Limited Partner Interest and shall extend to such Limited Partner’s heirs, successors, assigns and personal representatives. 
 (c) For
avoidance of doubt, this Section 16.01 shall not apply to any Series A Preferred Unitholder.

(a) Each of the Partners agrees to hold the Partnership’s Confidential Information in confidence and may not use such information except
in furtherance of the business of the Partnership, monitoring and evaluating its investment in the Partnership or as otherwise authorized separately in writing by the General Partner, it being understood that each Partner may disclose Confidential

with the Partnership’s business, in each case obtained by a Partner from the Partnership or any of its Affiliates or Representatives. With respect to any Partner, Confidential Information does not include information or material that:
(i) is rightfully in the possession of such Partner at the time of disclosure by or on behalf of the Partnership; (ii) before or after it has been disclosed to such Partner by or on behalf of the Partnership, becomes publicly available on
a non-confidential basis from a source other than the Partnership or its Representatives, other than as a result of any action or inaction of such Partner in violation of this Agreement; (iii) is approved
for release by written authorization of the Chief Executive Officer of the Partnership or of the Corporation; (iv) is disclosed to such Partner or its Representatives by a source other than the Partnership or its Representatives that is not, to
the knowledge of such Partner (after reasonable inquiry), in violation of any obligation of confidentiality owed to the Partnership with respect to such information; or (v) is or becomes independently developed by or on behalf of such Partner
or its Representatives without use of or reference to the Confidential Information in violation of this Agreement. Each Partner shall be responsible to the Partnership for any breach of this Section 16.02 by any of its
Representatives as though such breach was committed by such Partner. 
 (b) In the event that any Partner or its Representatives is
requested or required by Law, rule, regulation or legal, judicial or administrative process, including an audit or examination by a regulatory authority or self-regulatory organization (including by oral questions, interrogatories, requests for
information or documents, subpoena, civil investigative demand or similar process) to disclose any of the Confidential Information, such Partner shall use commercially reasonable efforts to provide the Partnership with prompt written notice so that
the Partnership may, at the Partnership’s sole cost and expense, seek a protective order or other appropriate remedy or waive compliance with the provisions of this Agreement, and such Partner shall use commercially reasonable efforts to
cooperate with the Partnership in any effort the Partnership undertakes to obtain a protective order or other remedy. In the event that such protective order or other remedy is not obtained, or that the Partnership waives compliance with the
provisions of Section 16.02(a), such Partner and its Representatives shall furnish only that portion of the Confidential Information that is required. Notwithstanding the foregoing, no such notice, cooperation or other
action set forth in this Section 16.02(b) shall be required by Partner to the extent such Partner or its Representatives are requested or required to disclose Confidential Information to the applicable regulatory
authorities or self-regulatory organizations having supervisory jurisdiction over such Partner or its Representatives during the course of any regulatory audit or examination. 

(c) Notwithstanding anything herein to the contrary, any Series A Preferred Unitholder may disclose the terms of such Series A Preferred
Unitholder’s investment in the Partnership and the performance of that investment (whether in customary information provided to investors in private equity funds, investment funds, investment vehicles or managed accounts managed by a Series A
Preferred Unitholder or its current or future Affiliates, in such Series A Preferred Unitholder’s or its current or future Affiliates’ fundraising materials, or in reports or accounts 

  
 82 

 
required to be made by such Series A Preferred Unitholder under applicable Law or otherwise), which disclosure may, for the avoidance of doubt, include: (i) the name of the Partnership;
(ii) the country in which the Partnership is located; (iii) the net asset value of such Series A Preferred Unitholder’s interest in the Partnership; (iv) the general economic or structural terms of such Series A Preferred
Unitholder’s interest in the Partnership; (v) the Partnership’s industry sector; and (vi) the aggregate percentage of such Series A Preferred Unitholder’s total private equity asset value attributable to such Series A
Preferred Unitholder’s interest in the Partnership or by private equity funds, investment funds, investment vehicles or managed accounts managed by such Series A Preferred Unitholder or its current or future Affiliates. 

Section 16.03 Amendments. Subject to Section 6.01(e), this Agreement may be amended
or modified solely by the General Partner. Notwithstanding the foregoing, but subject to Section 6.01(e), no amendment or modification (a) to this Section 16.03 may be made without the prior
written consent of each of the Partners, (b) that modifies the limited liability of any Partner, or increases the liabilities or obligations of any Partner, in each case, may be made without the consent of each such affected Partner,
(c) that materially alters or changes any rights, preferences or privileges of any Limited Partner Interests in a manner that is different or prejudicial relative to any other Limited Partner Interests, may be made without the approval of a
majority in interest of the Partners holding the Limited Partner Interests affected in such a different or prejudicial manner (excluding any such Limited Partner Interests held by the General Partner or any affiliates Controlled by the General
Partner), (d) that materially alters or changes any rights, preferences or privileges of a holder of any class of Limited Partner Interests in a manner that is different or prejudicial relative to any other holder of the same class of Limited
Partner Interests, may be made without the approval of the holder of Limited Partner Interests affected in such a different or prejudicial manner and (e) to any of the terms and conditions of this Agreement which terms and conditions expressly
require the approval or action of certain Persons may be made without obtaining the consent of the requisite number or specified percentage of such Persons who are entitled to approve or take action on such matter; provided, that the General
Partner, acting alone, may amend this Agreement to reflect the issuance of additional Units or Equity Securities in accordance with Section 3.04. 

Section 16.04 Title to Partnership Assets. Partnership assets shall be deemed to be owned by the Partnership
as an entity, and no Partner, individually or collectively, shall have any ownership interest in such Partnership assets or any portion thereof. The Partnership shall hold title to all of its property in the name of the Partnership and not in the
name of any Partner. All Partnership assets shall be recorded as the property of the Partnership on its books and records, irrespective of the name in which legal title to such Partnership assets is held. The Partnership’s credit and assets
shall be used solely for the benefit of the Partnership, and no asset of the Partnership shall be transferred or encumbered for, or in payment of, any individual obligation of any Partner.

To the Limited Partners at the addresses indicated on the signature pages hereto or such other addresses provided by the applicable Limited Partner and shown
on the records of the Partnership. 
 Section 16.06 Binding Effect; Intended Beneficiaries. This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. 

Section 16.07 Creditors. None of the provisions of this Agreement shall be for the benefit of or enforceable
by any creditors of the Partnership or any of its Affiliates, and no creditor who makes a loan to the Partnership or any of its Affiliates may have or acquire (except pursuant to the terms of a separate agreement executed by the Partnership in favor
of such creditor) at any time as a result of making the loan any direct or indirect interest in Partnership Profits, Losses, Distributions, capital or property other than as a secured creditor. 

Section 16.08 Waiver. No failure by any party to insist upon the strict performance of any covenant, duty,
agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute a waiver of any such breach or any other covenant, duty, agreement or condition. 

Section 16.09 Counterparts. This Agreement may be executed in separate counterparts, each of which will be an
original and all of which together shall constitute one and the same agreement binding on all the parties hereto. 

Section 16.10 Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws
of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the
State of Delaware. Any dispute relating hereto shall be heard in the state or federal courts of the State of Delaware, and the parties agree to jurisdiction and venue therein. 

  
 85 

 Section 16.11 Severability. Whenever possible, each
provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law or rule
in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or the effectiveness or validity of any provision in any other jurisdiction, and this Agreement will be reformed, construed and enforced in such
jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

Section 16.12 Further Action. The parties shall execute and deliver all documents, provide all information
and take or refrain from taking such actions as may be reasonably necessary or appropriate to achieve the purposes of this Agreement. 

Section 16.13 Delivery by Electronic Transmission. 

(a) This Agreement and any signed agreement or instrument entered into in connection with this Agreement or contemplated hereby, and any
amendments hereto or thereto, to the extent signed and delivered by means of an electronic transmission, including by a facsimile machine or via email, shall be treated in all manner and respects as an original agreement or instrument and shall be
considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of electronic transmission by a facsimile machine or via email to
deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through such electronic transmission as a defense to the formation of a contract and each such party forever waives any such defense. 

(b) Documents required to be delivered by the Partnership to the Partners pursuant to this Agreement may be delivered electronically and shall
be deemed to have been so delivered on the date (i) on which the Partnership posts such documents, or provides a link thereto, on its website, the location of which may be communicated pursuant to the notice provisions set forth in
Section 16.05 or (ii) on which such documents are posted by the Partnership or the Corporation on the website of the SEC. 

Section 16.14 Right of Offset. Whenever the Partnership is to pay any sum (other than pursuant to Article
IV) to any Partner, any amounts that such Partner owes to the Partnership which are not the subject of a good faith dispute may be deducted from that sum before payment. For the avoidance of doubt, the distribution of Units to the Corporation
shall not be subject to this Section 16.14. 
 Section 16.15 Expenses. Except as
otherwise provided herein, each Partner shall bear its own expenses incurred in connection with the preparation, execution and performance of this Agreement and the transactions contemplated hereby including all fees and expenses of its
Representatives. 

  
 86 

 Section 16.16 Effectiveness. This Agreement shall be
effective immediately upon the Series A Preferred Unit Closing (the “Effective Time”). The Existing Limited Partnership Agreement shall govern the rights and obligations of the Partnership and the other parties to this
Agreement in their capacity as Partners prior to the Effective Time to the extent the Existing Limited Partnership Agreement is applicable to such other parties. For avoidance of doubt, the Existing Limited Partnership Agreement shall not govern the
rights and obligations of the Series A Preferred Unitholders. 
 Section 16.17 Entire Agreement. This Agreement and those
documents expressly referred to herein (including the Series A Preferred Unit Purchase Agreement, the Registration Rights Agreement and the Contribution Agreement) embody the complete agreement and understanding among the parties and supersede and
preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way. For the avoidance of doubt, the Existing Limited Partnership Agreement is
superseded by this Agreement as of the Effective Time and shall be of no further force and effect thereafter. 

Section 16.18 Remedies. Each Partner shall have all rights and remedies set forth in this Agreement and all
rights and remedies which such Person has been granted at any time under any other agreement or contract and all of the rights which such Person has under any Law. Any Person having any rights under any provision of this Agreement or any other
agreements contemplated hereby shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted
by Law. 
 Section 16.19 Descriptive Headings; Interpretation. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a substantive part of this Agreement. Whenever required by the context, any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular
form of nouns, pronouns and verbs shall include the plural and vice versa. The use of the word “including” in this Agreement shall be by way of example rather than by limitation. Reference to any agreement, document or instrument means
such agreement, document or instrument as amended or otherwise modified from time to time in accordance with the terms thereof, and if applicable hereof. Without limiting the generality of the immediately preceding sentence, no amendment or other
modification to any agreement, document or instrument that requires the consent of any Person pursuant to the terms of this Agreement or any other agreement will be given effect hereunder unless such Person has consented in writing to such amendment
or modification. Wherever required by the context, references to a Fiscal Year shall refer to a portion thereof. The use of the words “or,” “either” and “any” shall not be exclusive. The serial comma is sometimes
included and sometimes omitted. Its inclusion or omission shall not affect the interpretation of any phrase. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of
intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions
of this Agreement. Wherever a conflict exists between this Agreement and any other agreement, this Agreement shall control but solely to the extent of such conflict. 

  
 87 

 Section 16.20 No Recourse. Notwithstanding anything that
may be expressed or implied in this Agreement or any document, agreement, or instrument delivered contemporaneously with this Agreement, and notwithstanding the fact that any Partner may be a partnership or limited liability company, each Partner
agrees and acknowledges that no Persons other than the Partners shall have any obligation under this Agreement. Each party to this Agreement further acknowledges and agrees that it has no rights of recovery whether under this Agreement or under any
documents, agreements, or instruments delivered contemporaneously herewith, in respect of any oral representations made or alleged to be made in connection herewith or therewith. The prohibition against recovery set forth in this
Section 16.20 shall have equal application to any and all claims against any former, current or future director, officer, agent, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative or employee of any
Limited Partner (or any of their successors or permitted assignees), against any former, current, or future general or limited partner, manager, stockholder or member of any Partner (or any of their successors or permitted assignees) or any
Affiliate thereof or against any former, current or future director, officer, agent, employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of
any of the foregoing, but in each case not including the Limited Partners. The prohibition set forth in this Section 16.20 shall apply to any and all claims, whether in tort, contract or otherwise. This prohibition shall apply whether
such claims are asserted by attempting to pierce the corporate veil, or through a claim brought by or on behalf of such party hereto against such Persons and whether by the enforcement of any assessment or by any legal or equitable proceeding, or by
virtue of any statute, regulation or other applicable law, or otherwise. The parties hereto further expressly agree and acknowledge that no personal liability whatsoever shall attach to or be incurred by any of the Persons or other entities
referenced in this Section 16.20 for any obligations of the applicable party hereto under this Agreement or the transactions contemplated hereby, under any documents or instruments delivered contemporaneously herewith, in respect of any
oral representations made or alleged to be made in connection herewith or therewith, or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, such obligations or their creation.
