 LIQUIDITY OPTION AGREEMENT 

THIS LIQUIDITY OPTION AGREEMENT (this “Agreement”) dated as of October 1, 2014 by and among Enterprise Products Partners
L.P., a Delaware limited partnership (“Enterprise”), and Oiltanking Holding Americas, Inc., a Delaware corporation (“OTA”), and Marquard & Bahls AG, a German Aktiengesellschaft (“M&B”).

 W I T N E S S E T H : 

WHEREAS, M&B indirectly through OTA owns certain equity interests in Oiltanking Partners L.P., a Delaware limited partnership
(“Oiltanking”), and its general partner, all as set forth in that certain Contribution and Purchase Agreement dated the date hereof (the “Purchase Agreement”); 

WHEREAS, effective on the date of this Agreement, Enterprise is acquiring certain interests in Oiltanking and its general partner pursuant to
the Purchase Agreement in exchange for consideration that includes cash and Enterprise Common Units (as defined herein); and 
 WHEREAS, as
partial consideration for the Purchase Agreement, Enterprise desires to grant to M&B an option for M&B to sell to Enterprise the Option Securities (as defined herein) upon the terms and subject to the conditions of this Agreement. 

NOW, THEREFORE, the parties hereto agree as follows: 

ARTICLE 1 

DEFINITIONS 

Section 1.01. Definitions. The capitalized defined terms used herein and not defined herein shall have the same meanings as set
forth in the Purchase Agreement. As used herein, the following terms have the following meanings: 
 “Cash Reserves” means
cash and any prepayment or deposit of Taxes that is creditable against Taxes of OTA under Applicable Law and refunds with respect to Taxes to which OTA is entitled. 

“Enterprise Tax Event” means the conversion by Enterprise into a corporation, including for U.S. federal income tax purposes,
or a combination of Enterprise with a corporation or partnership, including for U.S. federal income tax purposes, in which substantially all of the outstanding Enterprise Common Units are, for U.S. federal income tax purposes, exchanged or deemed to
be exchanged for cash or property, in each case to the extent such transaction, event, circumstance, condition or state of facts is, for U.S. federal income tax purposes, taxable in whole or in substantial part to holders of Enterprise Common Units
(determined without regard to whether any particular holder of Enterprise Common Units has a built-in loss in those units at the time of such transaction, event, circumstance, condition or state of facts) (a “Corporate Conversion”);
provided, however, that (i) for purposes of this definition, a transaction shall be treated as taxable in substantial part if OTA recognizes 20% or more of its built-in gain in its Enterprise Common Units at the time of such
transaction, and (ii) the term 







 
“Enterprise Tax Event” shall not include a Corporate Conversion that would not have occurred but for a change in Applicable Law, including the Code or final or temporary Treasury
Regulations, or in a judicial opinion or published ruling interpreting the provisions thereof, occurring after the date of this Agreement. 

“Excluded Taxes” means any Taxes payable by any OTA Entity as a result of an Enterprise Tax Event. For clarification and
avoidance of doubt, there will be no Excluded Taxes if M&B does not exercise the Liquidity Option during the 135-day period following a Trigger Event caused by an Enterprise Tax Event. 

“Exercise Period” means (i) in the absence of a Trigger Event, the 90-day period beginning on the five year and
four-month (64-month) anniversary of the date hereof, or (ii) if a Trigger Event occurs before the end of the period described in clause (i), the 135-day period beginning on the date on which M&B has received written notice from Enterprise
of the occurrence of the Trigger Event. 
 “Foreign Holdco” means any entity that is organized in a non-U.S. jurisdiction
(excluding any jurisdiction on the OECD’s Financial Action Task Force “Blacklist” of “Non-Cooperative Countries or Territories” as of the date of this Agreement or such list or any successor list as of the Exercise Date or
Settlement Date) and whose only assets as of the Exercise Date and Settlement Date consist of 100% of the securities that would have constituted Option Securities in the absence of Section 2.04(d) of this Agreement. 

“knowledge of M&B and OTA,” “M&B’s and OTA’s knowledge” or any other similar knowledge
qualification in this Agreement means to the actual knowledge, after reasonable inquiry, of the chief financial officer and general counsel of M&B or persons with comparable titles and responsibilities. 

“material” or “materially” when used with respect to OTA means having a value in excess of $1,000,000. 

“M&B Disclosure Schedules” means the disclosure schedules delivered by M&B to Enterprise prior to the date of this
Agreement (which disclosure schedules may be supplemented by M&B to reflect post-signing developments and matters that, to the knowledge of M&B, if not included on the M&B Disclosure Schedule, would constitute a breach of this Agreement,
such supplement to be delivered with the Exercise Notice). 
 “OTA Entity” or “OTA Entities” means OTA and
its Subsidiaries. 
 “Permitted Closing Liabilities” means liabilities of OTA at Closing that are permitted under
Section 8.02(d)(ii). 
 “Pre-Closing Taxes” means (i) any Taxes owed by M&B and any of its Affiliates (other
than OTA) for any taxable period, (ii) any Taxes imposed upon the OTA Entities with respect to (A) any period ending on or before Closing (a “Pre-Effective Period”) or (B) any taxable period beginning on or before,
and ending after, the Settlement Date (a “Straddle Period”), but only 

  
 2 








 
with respect to the portion of such Straddle Period ending on and including the Settlement Date (such portion, a “Pre-Effective Straddle Period”) as determined pursuant to
Section 7.05, (iii) any Taxes attributable to periods, or portions thereof, ending on or before Closing for which any OTA Entity is held liable (A) as a transferee or otherwise through operation of law by reason of a transaction
occurring prior to Closing, or (B) as a result of any Tax sharing, Tax indemnity or Tax allocation agreement or any express agreement to indemnify any other Person entered into prior to Closing and (iv) any Taxes imposed as a result of any
OTA Entity having filed any Tax Return on a combined, consolidated, unitary, affiliated or similar basis with another Person prior to the Settlement Date; provided, however, that notwithstanding the foregoing, “Pre-Closing
Taxes” shall not include any Excluded Taxes. 
 “Reference Security” means the Enterprise Common Units (or the equity
interests of any successor to Enterprise issued in exchange for Enterprise Common Units, including the equity interests of any entity in a merger of Enterprise with or into another entity in which equity interests of such successor parent entity are
issued in exchange for Enterprise Common Units). 
 “Restructuring Transaction” means the acquisition of the Option
Securities by M&B by way of (i) a purchase, (ii) an in-kind distribution or (iii) an in-kind contribution in which M&B issued cash, non-qualified preferred stock (within the meaning of Section 351 of the Code),
indebtedness or common stock. 
 “Trigger Event” means (i) any transaction, event, circumstance, condition or state of
facts by which the Enterprise Common Units (or any other Reference Security) cease to be “regularly traded” within the meaning of Section 897 of the Code and the Treasury Regulations thereunder, (ii) any transaction, event,
circumstance, condition or state of facts by which OTA becomes the owner, for purposes of Section 897 of the Code, of Enterprise Common Units (or any other Reference Security) representing more than 5% of all outstanding Enterprise Common Units
(or such Reference Securities) other than as a result solely of the acquisition of Enterprise Common Units or other Reference Securities by OTA, M&B or any Affiliate after the date of this Agreement or (iii) any Enterprise Tax Event. 

Section 1.02. Other Definitional and Interpretative Provisions. The words “hereof,” “herein” and
“hereunder,” and words of like import used in this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The captions herein are included for convenience of reference only and shall be
ignored in the construction or interpretation hereof. References to Articles, Sections, Exhibits and Schedules are to Articles, Sections, Exhibits and Schedules of this Agreement unless otherwise specified. All Exhibits and Schedules annexed hereto
or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth in full herein. Any capitalized terms used in any Exhibit or Schedule but not otherwise defined therein shall have the meaning as defined in this
Agreement. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be
deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing and other
means of reproducing words (including electronic media) in a visible form. References to any statute shall be deemed to refer to such statute as 

  
 3 








 
amended from time to time and to any rules or regulations promulgated thereunder. References to any agreement or contract are to that agreement or contract as amended, modified or supplemented
from time to time in accordance with the terms hereof and thereof; provided that with respect to any agreement or contract listed on any schedules hereto, all such amendments, modifications or supplements must also be listed in the
appropriate schedule. References to any Person include the successors and permitted assigns of that Person to the extent the context so requires. References from or through any date mean, unless otherwise specified, from and including or through and
including, respectively. 
 ARTICLE 2 

LIQUIDITY OPTION 

Section 2.01. Liquidity Option. Upon the terms, and subject to the conditions, of this Agreement: 

(a) Enterprise hereby grants M&B the option (the “Liquidity Option”) to sell to Enterprise all of the outstanding capital
stock of OTA (the “Option Securities”). The Liquidity Option can only be exercised by written notice by M&B to Enterprise (the “Exercise Notice”) during the Exercise Period (the date in the Exercise Period on
which M&B actually provides notice of such exercise, the “Exercise Date”). If M&B exercises the foregoing Liquidity Option on or prior to the Exercise Date, upon the terms and subject to the conditions of this Agreement,
Enterprise agrees to acquire and accept from M&B the Option Securities and to pay to M&B the Strike Price on the seventh (7th) Business Day following the Exercise Date (the “Settlement Date”). The Liquidity Option shall
be exercisable only with respect to all of the outstanding Option Securities and shall not be partially exercisable. The Liquidity Option may not be exercised by M&B, and any delivery of the Exercise Notice shall be invalid with respect thereto,
if on the Exercise Date any of the conditions to Closing that are set forth in Sections 8.01 and 8.02 are not already capable of being satisfied as of the Exercise Date (including any representations and warranties that speak as of the Settlement
Date, which shall be read as if they were as of the Exercise Date). 
 (b) The Exercise Notice delivered by M&B shall contain statements
and certification of the following matters signed by an executive of M&B: 
 (i) a statement affirming that the Liquidity
Option is exercisable in compliance with the last sentence of Section 2.01(a); 
 (ii) copies of the financial
statements described in Section 3.06; 
 (iii) the number of Enterprise Common Units (or other Reference Securities)
that are owned by OTA on the Exercise Date and will be owned by OTA at Closing (the “OTA-Owned Enterprise Common Units”); 

(iv) the amount of indebtedness of OTA, if any (or a statement that the amount is zero), that will be satisfied or released
prior to Closing; 

  
 4 








 (v) a reasonably-detailed description of the liabilities, if any (or a statement
that there will be none), permitted by Section 8.02(d)(ii)(B) that are to remain with OTA, the dollar value of each such liability, and the total amount of cash also remaining with OTA, all estimated as of the Settlement Date; and 

(vi) a calculation of the Strike Price. 

Section 2.02. Strike Price. (a) The aggregate consideration to be paid by Enterprise for the Option Securities
(“Strike Price”) shall consist of an amount equal to 100% of the fair market value of the OTA-Owned Enterprise Common Units at the Closing, to be determined by multiplying the number of OTA-Owned Enterprise Common Units by the
volume-weighted sales price per unit taken to four decimal places of Enterprise Common Units (or, if applicable, Reference Securities) as reported by the New York Stock Exchange (or such other national securities exchange on which the Enterprise
Common Units or Reference Securities are principally traded) for the consecutive period of ten (10) trading days beginning at 9:30 a.m. New York time on the eleventh (11th) trading day immediately preceding the Exercise Date and concluding
at 4:00 p.m. New York time on the trading day immediately preceding the Exercise Date, as calculated by Bloomberg Financial LP under the function “VWAP” (or, if not available from this source or function, as calculated with the
volume-weighted sales price per unit information reported on the applicable exchange). 
 (b) The Strike Price may be paid in (i) cash
in immediately available funds, (ii) Enterprise Common Units or (iii) any combination thereof, as determined by Enterprise in its sole discretion. If any Enterprise Common Units are delivered by Enterprise as part of the Strike Price, then
those units shall be valued in the same manner as set forth in Section 2.02(a). 
 Section 2.03. Closing. The closing (the
“Closing”) of the transactions provided for in Section 2.01 shall take place at the offices of Enterprise in Houston, Texas on the Settlement Date after satisfaction or, to the extent permissible, waiver by the party or parties
entitled to the benefit of the conditions set forth in ARTICLE 8 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permissible, waiver of those conditions at the
Closing), or at such other time or place as Enterprise and M&B may agree. At the Closing: 
 (a) Enterprise shall deliver or cause to be
delivered to M&B: 
  

	 	(i)	the cash consideration, if any, portion of the Strike Price, in immediately available funds by wire transfer to an account of M&B designated by M&B in the Exercise Notice (or if not so designated, then by
certified or official bank check payable in immediately available funds to the order of M&B in such amount); 

  

	 	(ii)	an appropriate number of Enterprise Common Units, if any, as a portion of the Strike Price in restricted book-entry form in the name of M&B with the transfer agent; 


  
 5 









	 	(iii)	a Registration Rights Agreement in the form attached hereto as Exhibit A (the “Registration Rights Agreement”), duly executed by Enterprise; 


 

	 	(iv)	the cross receipt in the form attached hereto as Exhibit B (the “Cross Receipt”), duly executed by Enterprise; and 


 

	 	(v)	all other documents, instruments or certificates required to be delivered by Enterprise at or prior to the Closing pursuant to this Agreement. 


(b) M&B shall deliver or cause to be delivered to Enterprise: 
  

	 	(i)	certificates for the Option Securities duly endorsed or accompanied by stock powers duly endorsed in blank, with any required transfer stamps affixed thereto; 


 

	 	(ii)	all other documents and instruments necessary to vest in Enterprise all of M&B’s right, title and interest in and to the Option Securities, free and clear of all Liens; 


 

	 	(iii)	all minute books and other similar records of OTA; 

  

	 	(iv)	the OTA-Owned Enterprise Common Units in book-entry form in the name of OTA with the transfer agent; 

  

	 	(v)	except to the extent that the Option Securities consist of securities of Foreign Holdco in accordance with Section 2.04(d), a certification, signed under penalties of perjury as of the Settlement Date, from OTA
that satisfies the requirements of Treasury Regulation Sections 1.897-2(g)(ii)(B) and 1.897-2(h) and confirms that the Option Securities are not U.S. Real Property Interests within the meaning of Section 1.897-1(c) of the Code;


  

	 	(vi)	the Registration Rights Agreement, duly executed by M&B; 

  

	 	(vii)	the Cross Receipt, duly executed by M&B; and 

  

	 	(viii)	all other documents, instruments or certificates required to be delivered by M&B or OTA at or prior to the Closing pursuant to this Agreement. 


Section 2.04. Trigger Events. Notwithstanding anything to the contrary in this Agreement, upon the occurrence of a Trigger Event:

 (a) Enterprise shall promptly notify M&B in writing when it becomes aware that the Trigger Event has occurred; 

(b) the Liquidity Option shall become immediately exercisable by M&B; 

  
 6 








 (c) notwithstanding Section 8.01(b), the Restructuring Transaction shall not be a condition
to the exercise or settlement of the Liquidity Option; 
 (d) at the election of M&B in its sole discretion, the term “Option
Securities” shall, in lieu of the definition of “Option Securities” set forth in Section 2.01(a) and for all purposes of this Agreement, mean all of the outstanding equity interests of Foreign Holdco; 

(e) the Strike Price shall be an amount equal to 100% of the fair market value of the OTA-Owned Enterprise Common Units immediately prior to
the Trigger Event, determined in a manner consistent with the valuation standards set forth in Section 2.02(a); 
 (f) the Strike Price
shall be paid by Enterprise entirely in cash; 
 (g) no Registration Rights Agreement will be executed and delivered; 

(h) without limiting the assignments otherwise permitted by Section 11.04, M&B shall be entitled to assign the Liquidity Option to,
and the Liquidity Option may thereafter be exercised by, Oiltanking GmbH; and 
 (i) the terms and conditions of the Liquidity Option, as
set forth in this Agreement, shall otherwise continue to apply, mutatis mutandis; provided, however, that the Liquidity Option may not be settled with respect to Foreign Holdco if Foreign Holdco or OTA has any assets or
liabilities other than (i) assets and liabilities permitted by Section 8.02(d) and (ii) for the avoidance of doubt, equity interests of OTA held by Foreign Holdco. 

ARTICLE 3 

REPRESENTATIONS AND WARRANTIES OF M&B PARTIES 

Each of M&B and OTA, jointly and severally, represents and warrants to Enterprise as of the date of this Agreement and as of the
Settlement Date (except for any representations and warranties made as of a specific date, which shall be true at and as of such date) that: 

Section 3.01. Corporate Existence and Power. (a) OTA is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted, and is duly qualified, registered or
licensed to do business as a foreign entity and is in good standing in each jurisdiction in which the nature of the business conducted by it makes such qualification necessary, except where the failure to be so duly qualified, registered or licensed
and in good standing would not reasonably be expected to result in liabilities that are not Permitted Closing Liabilities. 
 (b) M&B is
a legal entity duly organized and validly existing and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted, and is duly qualified, registered or licensed
to do business as a foreign entity in each jurisdiction in which the nature of the business conducted by it makes 

  
 7 








 
such qualification necessary, except where the failure to be so duly qualified, registered or licensed would not reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the transactions contemplated by this Agreement. 
 (c) M&B has made available prior to the date of this Agreement a
true and complete copy of OTA’s certificate of organization and bylaws, in each case as amended through the date hereof. 

Section 3.02. Corporate Authorization. The execution, delivery and performance by each of M&B and OTA of this Agreement and
each of the other transaction documents to which it is a party and the consummation of the transactions contemplated hereby and thereby (i) are within each party’s corporate (or other) powers and have been duly authorized by all necessary
corporate action on the part of such party and (ii) require no corporate (or other) action on the part of any owner of M&B. This Agreement is, and the other transaction documents to which they are a party will be when executed and delivered
at Closing, duly executed and delivered by each of M&B and OTA, as applicable. This Agreement constitutes, and each of the other transaction documents will constitute when entered into at Closing, a valid and binding agreement of each of M&B
and OTA, as applicable, enforceable against such party in accordance with the terms of the applicable agreement, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, moratorium and similar laws
relating to or affecting creditors’ rights generally. 
 Section 3.03. Governmental Authorization. The execution, delivery
and performance by each of M&B and OTA of this Agreement and the consummation of the transactions contemplated hereby require no consent or approval of, action by or in respect of, or filing with, any Governmental Authority other than such
consents, approvals, actions or filings that (i) are being obtained in compliance with Section 7.03 or have been obtained or made, (ii) that would in the ordinary course be made or obtained after the Closing or (iii), which if not
obtained or made, would not reasonably be expected to prevent or materially delay the consummation of the transactions contemplated hereunder or to materially impair any such party’s or its Affiliates’ ability to perform their respective
obligations hereunder. 
 Section 3.04. Noncontravention. The execution, delivery and performance by each of M&B and OTA of
this Agreement and the consummation of the transactions contemplated hereby do not and will not (i) violate the certificate of incorporation or bylaws or equivalent organizational or constituent documents of any such party, (ii) violate or
conflict with any Applicable Law, (iii) require any consent or other action by any Person under, constitute a default under, result in a violation of or conflict with, or give rise to any right of termination, cancellation, modification, or
acceleration of any right or obligation of any such party or to a loss of any benefit to which any such party is entitled under any provision of any agreement or other instrument binding upon any such party or (iv) result in the creation or
imposition of any Lien on any asset of OTA. 
 Section 3.05. Capitalization of OTA; Ownership of OTA-Owned Enterprise Common
Units. (a) All of the Option Securities have been duly authorized and validly issued in accordance with the governing documents of OTA, are fully paid and non-assessable and were not issued in violation of any pre-emptive rights, right of
first refusal, right of first offer or similar rights of any Person. 

  
 8 








 (b) There are no authorized, issued or outstanding (i) equity interests or voting securities
of OTA, (ii) securities of OTA convertible into or exchangeable for equity interests or voting securities of OTA or (iii) options or other rights to acquire, or other obligation of OTA to issue, any equity interests, voting securities or
securities convertible into or exchangeable for equity interests or voting securities of OTA. There are no outstanding obligations of OTA to repurchase, redeem or otherwise acquire any of the securities described in the foregoing sentence. As of the
Settlement Date, OTA will have no Subsidiaries. 
 (c) As of the Exercise Date and the Settlement Date, OTA owns the number of OTA-Owned
Enterprise Common Units set forth in the Exercise Notice, in each case, free and clear of any Liens (other than Liens to be released at Closing). Other than such OTA-Owned Enterprise Common Units, as of the Settlement Date, OTA does not own any
stock or equity ownership (whether controlling or not) in a corporation, association, partnership, limited liability company, joint venture or other entity. 

Section 3.06. Financial Statements. Except as set forth in the M&B Disclosure Schedules, the audited consolidated financial
statements of OTA for the most recent three (3) fiscal years prior to the submission of the Exercise Notice and the most recent unaudited consolidated interim financial statements of OTA (the last day of such interim statements, the

Enterprise and each of M&B and OTA agree that: 

Section 7.01. Reasonable Best Efforts; Further Assurances. (a) Subject to the terms and conditions of this Agreement,

Enterprise, the requirements of the NYSE. 
 Section 7.03. Regulatory Approvals. Although neither M&B and OTA, on the one
hand, and Enterprise, on the other, are aware of any regulatory approvals under Applicable Law that are required with respect to the transactions contemplated hereby (“Required Regulatory Approvals”), if such approvals become

with respect thereto. If necessary, the Exercise Period shall be extended for a reasonable period of time to accommodate such approval process under Applicable Law, but not beyond the 90th Business Day following the Exercise Date. 

Section 7.04. Notices of Certain Events. Each party shall promptly notify the other of: 

(a) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the
transactions contemplated by this Agreement; 
 (b) any notice or other communication from any Governmental Authority in connection with the
transactions contemplated by this Agreement; 
 (c) any event, condition or development that, individually or in the aggregate, has resulted
in (or, in the case of representations and warranties, would result in) the inaccuracy or breach of any representation or warranty, covenant or agreement contained in this Agreement made or to be made by or to be complied with by such notifying
party at any time during the term hereof and that would reasonably be expected to result in any of the conditions set forth in ARTICLE 8 not to be satisfied; provided, however, that no such notification shall be deemed to cure any such
breach of or inaccuracy in such notifying party’s representations and warranties or covenants and agreements for any purpose under this Agreement and no such notification shall limit or otherwise affect the remedies available to the other
parties, including any right to indemnification; or

applicable local law for filing such Tax Returns, and such party will use 

  
 16 








 
reasonable best efforts to provide such Tax Returns to the other party at least ten (10) days prior to the due date, including extensions, for such Tax Returns. Upon the filing of Tax
Returns in connection with Transfer Taxes, the filing party shall provide the other party with evidence satisfactory to the other party that such Transfer Taxes have been filed and paid. 

(b) M&B shall be liable for, shall pay and shall protect, defend, indemnify and hold harmless Enterprise and its subsidiaries from and
against all losses such parties incur arising from (i) any breach of the representations and warranties contained in Section 3.15 (determined without regard to any materiality or similar qualifier) and (ii) any Pre-Closing Taxes, in
each case to the extent a Cash Reserve was not established for such Taxes. For purposes of determining the portion of any Taxes imposed on the OTA Entities for any Straddle Period that are Pre-Closing Taxes, the portion of such Taxes attributable to
the Pre-Effective Straddle Period shall, in the case of any Taxes that are imposed on a periodic basis and are payable for the Straddle Period, be (A) in the case of any Taxes other than Taxes based upon or related to income or receipts, deemed
to be the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in the taxable period ending on the Settlement Date and the denominator of which is the number of days in the entire
taxable period, and (B) in the case of any Tax based upon or related to income or receipts, deemed equal to the amount which would be payable if the relevant taxable period ended on the Settlement Date. Any Tax refund (including any interest
with respect thereto) relating to any OTA Entity for any Pre-Effective Period or Pre-Effective Straddle Period shall, to the extent not used as an offset to Taxes for purposes of Section 8.02(d), be the property of M&B and, if received by
Enterprise or OTA after the Closing, shall be paid over promptly to M&B (or, if an indemnity payment is owed by M&B to Enterprise under this Agreement, shall reduce the amount of such indemnity payment). 

(c) M&B shall have the sole right to represent each OTA Entity (and, if applicable, Foreign Holdco) in any federal, state, local or
foreign Tax audit, examinations, assessment or administrative or court proceeding (“Tax Contest”) relating to taxable periods ending on or before the Settlement Date or otherwise relating to Taxes for which M&B or any of its
Affiliates may be liable pursuant to this Agreement. In the event that a Tax Contest involves Tax items or issues of the OTA Entities (or, if applicable, Foreign Holdco) for a Straddle Period, the parties shall endeavor to cause the Tax Contest
proceeding to be separated into two or more separate proceedings, one of which shall involve exclusively the applicable Straddle Period. In the event that such separation cannot, after diligent efforts, be achieved, M&B and Enterprise shall
jointly control the Tax Contest and each party shall be entitled to participate at its expense in any Tax Contest relating (in whole or in part) to Taxes attributable to the portion of such Straddle Period ending on and including the Settlement
Date; provided, however, that (i) M&B shall have no right to control any Tax Contest unless M&B shall have first notified Enterprise in writing of M&B’s intention to do so and (ii) Enterprise and its
representatives shall be permitted to, at Enterprise’s expense, participate in any Tax Contest and, if M&B does not assume the defense of any Tax Contest, Enterprise may defend the same in such manner as it may deem appropriate, including,
but not limited to, settling such Tax Contest after giving twenty (20) days’ prior written notice to M&B setting forth the terms and conditions of settlement. 

  
 17 








 (d) M&B shall prepare and file or cause to be filed when due (taking into account all
extensions properly obtained) all Tax Returns that are required to be filed by or with respect to OTA (and, if applicable, Foreign Holdco) for taxable years or periods ending on or before the Settlement Date in accordance with its prior practice
(except as otherwise required by Applicable Law), and Enterprise shall prepare and file or cause to be filed when due (taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to OTA for
taxable years or periods beginning after the Settlement Date and all Tax Returns for any Straddle Period; provided, however, with respect to any such Tax Return for any Straddle Period, such Tax Return shall be prepared on a basis
consistent with the last previous such Tax Return (except as otherwise required by Applicable Law), and Enterprise shall provide to M&B a copy of each such Tax Return at least twenty (20) days prior to the due date of such Tax Return
(taking into account all applicable extensions) for its review and comment, such reasonable comments of M&B received by Enterprise at least five (5) days prior to such due date to be incorporated by Enterprise in such Tax Return as actually
filed. Enterprise shall cause OTA (and, if applicable, Foreign Holdco) to timely pay any Taxes of OTA (or Foreign Holdco) that are due after the Settlement Date and M&B shall promptly pay to Enterprise the amount of any such Taxes that are
Pre-Closing Taxes for which Cash Reserves have not been established, subject to Enterprise’s right to indemnification for the Taxes described in Section 7.05(b). 

(e) Subject to Section 7.05(c), the parties shall cooperate fully, and cause their Affiliates to cooperate fully, as and to the extent
reasonably requested by the other party, to accomplish the apportionment of income described pursuant to this Section 7.05 and to promptly respond to requests for the provision of any information or documentation within the knowledge or
possession of the other party as reasonably necessary to facilitate compliance with financial reporting obligations arising under Financial Accounting Standards Board (“FASB”) Statement No. 109 (including compliance with FASB
Interpretation No. 48), and any Tax Contest. Such cooperation shall include access to, the retention of and (upon the other party’s request) the provision of records and information which are reasonably relevant to any Tax Return or Tax
Contest, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The parties each agree, upon request, to use reasonable efforts to obtain any certificate or
other document from any Tax Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated by this Agreement. 

(f) Notwithstanding anything to the contrary herein, to the extent any other provision of this Agreement conflicts with this Section 7.05
with respect to any claims relating to Taxes (including any claims relating to representations respecting Tax matters including Section 3.15), this Section 7.05 shall govern. No claim may be made or brought by any party hereto after the
expiration of the applicable survival period unless such claim has been asserted by written notice specifying the details supporting the claim on or prior to the expiration of the applicable survival period. The rights under this Section 7.05
shall survive the Closing until thirty (30) days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter; provided that any claim for indemnification pursuant to Section 7.05(b) shall survive
the time at which it would otherwise terminate pursuant to the preceding sentences, if proper notice of such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

Contingent Liability in accordance with the provisions of this Section 8.05, (A) M&B shall obtain the prior written consent of Enterprise (which shall not be unreasonably withheld, conditioned or delayed) before entering into any

equitable relief against Enterprise or any of its Affiliates and (B) Enterprise shall be entitled to participate in the handling of any Contingent Liability for such purpose. 

ARTICLE 9 

SURVIVAL; INDEMNIFICATION 

Section 9.01. Survival. The representations and warranties of M&B and OTA hereto contained in this Agreement or in any

representation, warranty, covenant or agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to the preceding sentences, if notice of the inaccuracy or breach
thereof giving rise to such right of indemnity shall have been duly given, in accordance with the procedures and requirements set forth in this ARTICLE 9, to the party against whom such indemnity may be sought prior to such time. 

  
 21 








 Section 9.02. Indemnification. (a) Effective at and after the Closing, M&B
hereby indemnifies Enterprise and its Affiliates (including OTA following the Closing) against and agrees to hold each of them harmless from any and all Damages actually incurred or suffered by Enterprise or any of its Affiliates arising out of
(i) any liabilities of OTA or of M&B as its stockholder, of any kind whether or not accrued or fixed, absolute or contingent, matured or unmatured, or determined or undetermined or otherwise, including any of which arise out of, result
from, or relate to the conduct of OTA’s business prior to the Closing or which may be asserted against or imposed upon Enterprise as a successor or transferee of M&B or OTA or as an acquirer of the Option Securities or OTA’s business
or otherwise as a matter of law, (ii) any misrepresentation, breach or inaccuracy of any of the M&B Fundamental Representations or M&B Special Representations or (iii) any breach of covenant or agreement made or to be performed by
each of M&B and OTA pursuant to this Agreement. 
 (b) Effective at and after the Closing, Enterprise hereby indemnifies M&B and its
Affiliates against and agrees to hold each of them harmless from any and all Damages actually incurred or suffered by M&B or any of its Affiliates arising out of (i) any misrepresentation, breach or inaccuracy of any of the Enterprise
Fundamental Representations or Enterprise Special Representations or (ii) any breach of covenant or agreement made or to be performed by Enterprise pursuant to this Agreement. 

Section 9.03. Third Party Claim Procedures. (a) The party seeking indemnification under Section 9.02 (the
“Indemnified Party”) agrees to give prompt notice in writing to the party against whom indemnity is to be sought (the “Indemnifying Party”) of the assertion of any claim or the commencement of any Proceeding by any
third party (“Third Party Claim”) in respect of which indemnity may be sought under such Section. Such notice shall set forth in reasonable detail the specifics of such Third Party Claim, the basis for indemnification and the
Indemnified Party’s bona fide estimate of the amount of such Third Party Claim (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder, except to the extent such failure shall have actually adversely prejudiced the Indemnifying Party. 

(b) The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations set forth
in this Section, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense; provided that the Indemnified Party is hereby authorized, prior to the Indemnifying Party’s delivery of a written
election to the Indemnified Party of its agreement to defend such Third Party Claim, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnifying Party. 

(c) If the Indemnifying Party elects to assume the defense of any such Third Party Claim, it shall within thirty (30) days after receipt
of the notice referred to in Section 9.03(a) notify the Indemnified Party in writing of its intent to do so. The Indemnifying Party will have the right to assume control of such defense of the Third Party Claim only for so long as it


  
 22 








 
conducts such defense with reasonable diligence. The Indemnifying Party shall keep the Indemnified Parties advised of the status of such Third Party Claim and the defense thereof on a reasonably
current basis and shall consider in good faith the recommendations made by the Indemnified Parties with respect thereto. If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of
this Section 9.03, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement of such Third Party Claim,
if the settlement or compromise does not release the Indemnified Party and its Affiliates from all liabilities and obligations with respect to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the
Indemnified Party or any of its Affiliates and (ii) the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose. The fees and expenses of such
separate counsel shall be paid by the Indemnified Party. 
 (d) The Indemnified Party shall not settle or compromise any Third Party Claim,
or take any corrective or remedial action or enter into an agreed judgment or consent decree with respect thereto, that subjects the Indemnified Party to any criminal liability, requires an admission of guilt or wrongdoing on the part of the
Indemnified Party or imposes any continuing obligation on or requires any payment from the Indemnified Party without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld, conditioned or delayed). 

(e) Each party shall reasonably cooperate, and cause their respective controlled Affiliates to reasonably cooperate, in the defense or
prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection
therewith. 
 Section 9.04. Direct Claim Procedures. In the event an Indemnified Party has a claim for indemnity under
Section 9.02 against an Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice shall set forth in reasonable detail the
specifics of such claim, the basis for indemnification and the Indemnified Party’s bona fide estimate of the amount of such claim (taking into account the information then available to the Indemnified Party). The failure to so notify the
Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually adversely prejudiced the Indemnifying Party. If the Indemnifying Party disputes its indemnity obligation
for any Damages with respect to such claim, the parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of
jurisdiction determined pursuant to Section 11.06. 
 Section 9.05. Calculation of Damages. (a) The amount of any
Damages payable under Section 9.02 by the Indemnifying Party shall be net of any amounts actually recovered by the Indemnified Party under applicable insurance policies or from any other Person alleged to be responsible therefor. If the
Indemnified Party receives any amounts under applicable insurance 

  
 23 








 
policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly
reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any reasonable expenses
incurred by such Indemnified Party in collecting such amount. 
 (b) The Indemnifying Party shall not be liable under Section 9.02 for
any (i) punitive, special, indirect, consequential, remote or speculative Damages of any kind or nature or (ii) Damages for lost profits, except with respect to Damages for lost profits, to the extent a court of competent jurisdiction
determined that lost profits is the appropriate measure of direct damages with respect to the matters giving rise to the claim for Damages (it being understood and agreed that such calculation of Damages shall not be based on any application of
revenue or earnings multiples to direct damages); provided that nothing herein shall prevent an Indemnified Party from recovering all components of awards against them in Third Party Claims for which recovery is provided in this ARTICLE 9.

 (c) Each Indemnified Party must take commercially reasonable efforts to mitigate in accordance with Applicable Law any Damages for which
such Indemnified Party seeks indemnification under this Agreement. If such Indemnified Party mitigates its loss after the Indemnifying Party has paid the Indemnified Party under any indemnification provision of this Agreement in respect of such
Damages, the Indemnified Party must notify the Indemnifying Party and pay to the Indemnifying Party the extent of the value of the benefit to the Indemnified Party of that mitigation (less the Indemnified Party’s reasonable costs of mitigation)
promptly after the benefit is received. To the extent recovery and collection is obtained, the amount of any Damages with respect to such indemnification claim will be reduced accordingly. 

(d) Each Indemnified Party shall use commercially reasonable efforts to seek recovery and collect any amounts available under insurance
coverage, or from any other Person alleged to be responsible, for any Damages payable under Section 9.02. 
 Section 9.06.
Exclusivity. After the Closing, except for any claim arising in respect of fraud, Section 7.05 and Section 9.02 will provide the exclusive remedies for any misrepresentation, or breach of warranty, or of covenant or other agreement
or other claim arising out of this Agreement or the transactions contemplated hereby (other than equitable remedies as they relate to breaches of covenants or other agreements contained herein to the extent such covenants or agreements are to be
performed prior to Closing. 
 Section 9.07. Purchase Price Adjustment. Any amount paid by M&B or Enterprise under
Section 7.05 or ARTICLE 9 will be treated as an adjustment to the Strike Price. 
 ARTICLE 10 

TERMINATION 

Section 10.01. Grounds for Termination. This Agreement may be terminated at any time prior to the Closing: 

(a) by M&B in its sole discretion; 

  
 24 








 (b) by either M&B or Enterprise if consummation of the transactions contemplated hereby would
violate any non-appealable final Order of any Governmental Authority having competent jurisdiction;

following the Exercise Period, if the Exercise Notice is not received by Enterprise on or prior to the end of the Exercise Period; and

The party desiring to terminate this Agreement pursuant to clauses (a) or (b) of this Section 10.01 shall give notice of such
termination to the other party. 
 Section 10.02. Effect of Termination. If this Agreement is terminated as permitted by
Section 10.01, such termination shall be without liability of either party (or any stockholder or Representative of such party) to the other party to this Agreement; provided that if such termination shall result from the willful
(i) failure of either party to fulfill a condition to the performance of the obligations of the other party, (ii) failure to perform a covenant of this Agreement or (iii) breach by either party hereto of any representation or warranty
or agreement contained herein, such party shall be fully liable for any and all Damages incurred or suffered by the other party as a result of such failure or breach. The provisions of Sections 11.03, 11.05, 11.06 and 11.07 shall survive any
termination hereof pursuant to Section 10.01.

becomes unable or unwilling to, or for another reason ceases to, serve as a member of such board and Marquard & Bahls AG is entitled to designate such replacement director pursuant to the Purchase Agreement). 

ARTICLE II. 

REGISTRATION RIGHTS 

Section 2.01 Demand Rights. 

(a) Demand. Subject to Section 2.01(e), at any time from and after the issuance of the EPD Subject Units pursuant
to the Liquidity Option Agreement, any Holder or Holders of then-outstanding Registrable Securities may request, by written notice to Enterprise (i) that Enterprise prepare and file a registration statement under the Securities Act to permit
the public resale of the Registrable Securities either (A) in a specified Underwritten Offering (a “Demand Registration Statement”) or (B) from time to time as permitted by Rule 415 under the Securities Act (a
“Shelf Registration Statement”; and any Demand Registration Statement or Shelf Registration Statement, a “Registration Statement”; and any registration contemplated by clause (A) or (B), a “Demand
Registration”) or (ii) in the event that a Shelf Registration Statement covering such Holder’s or Holders’ Registrable Securities is already effective, that Enterprise engage in an Underwritten Offering in respect of such
Holder’s or Holders’ Registrable Securities (an “Offering Demand” and together with any Demand Registration, a “Demand”). Promptly upon receipt of a Demand, Enterprise shall give written notice thereof to
all other Holders. 
 (b) Procedure related to Demands. In the case of any Demand, all Holders who notify Enterprise
in writing within 15 days after the date of notice of such Demand that they desire to include Registrable Securities in the Demand Registration Statement or in the Underwritten Offering pursuant to a Shelf Registration Statement shall be permitted
to do so. If applicable, Enterprise shall use its commercially reasonable efforts to cause a Registration Statement to be filed as promptly as practicable after the date of the Demand and to become effective as promptly as practicable following the
date of the filing thereof. A Registration Statement filed pursuant to this Section 2.01 shall be on such appropriate registration form of the Commission as shall be selected by Enterprise; provided, however, that with respect to
any request relating to a Shelf Registration Statement, the form of registration would be on Form S-3 if available (or any successor form, as applicable) and would permit a broad plan of distribution (including sales not involving a firm commitment
underwritten offering); provided, further, that if a 

  
 4 








 
prospectus or a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Registration Statement and the Managing Underwriter selected by the
Selling Holders at any time shall notify Enterprise in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus or prospectus supplement is of material importance to the success
of the Underwritten Offering of such Registrable Securities, Enterprise shall use its commercially reasonable efforts to include such information in such a prospectus or prospectus supplement. Enterprise will use its commercially reasonable efforts
to cause (i) a Shelf Registration Statement to remain continuously effective with respect to the resale of all Registrable Securities (including by filing as promptly as practicable, if requested by a Holder, any necessary post-effective
amendments to such Shelf Registration Statement or one or more successor Shelf Registration Statements, including for the purpose of including additional Selling Holders or adding Registrable Securities referenced in clause (ii) of the
definition of “Registrable Securities”) until all Registrable Securities have been distributed in the manner set forth and as contemplated in the Registration Statement or there are no longer any Registrable Securities outstanding covered
by such Registration Statement and (ii) a Demand Registration Statement to remain effective until all Registrable Securities have been distributed in the manner set forth and as contemplated in the Demand Registration Statement (as applicable,
the “Effectiveness Period”). Each Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form with all applicable requirements of the Securities Act and will not
contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As soon as practicable following the date a Registration Statement becomes
effective, but in any event within two Business Days after such date, Enterprise shall provide the Selling Holders with written notice thereof. To the extent that a Registration Statement does not become effective on or prior to the date 180 days
following the date of the filing thereof, other than at the fault of a Selling Holder, Enterprise shall pay to the Selling Holders as liquidated damages an amount equal to the lesser of (1) 0.25% of the amounts of securities requested to be
registered and (2) $2,500,000, prorated with respect to the number of days in and with respect to each six-month period after such date, until the Registration Statement becomes effective (the “Liquidated Damages”). 

(c) Delay Rights. Notwithstanding anything to the contrary contained herein, Enterprise may, upon written notice to any
Selling Holder whose Registrable Securities are included in a Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement (in which event the Selling Holder shall discontinue sales
of the Registrable Securities pursuant to the Registration Statement other than the closing of sales already committed for prior to receipt of such notice to suspend) if Enterprise (i) is actively pursuing a financing (other than pursuant to
any ATM Program), acquisition, merger, reorganization, disposition or other similar transaction and determines in good faith that its ability to pursue or consummate such a transaction would be materially adversely affected by any required
disclosure of such transaction in the Registration Statement or any related prospectus, (ii) determines that an amendment or supplement to the Registration Statement is necessary, or (iii) has experienced some other material non-public
event the disclosure of which at such time, in 

  
 5 








 
the good faith judgment of Enterprise, would be material and adverse; provided, however, that in no event shall the Selling Holders be suspended for a period exceeding an aggregate
of 90 days (exclusive of days covered by any lock-up agreement executed by a Holder in connection with any Underwritten Offering by the Holders) in any 365-day period. Upon disclosure of such information or the termination of the condition described
above, Enterprise shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement and shall promptly terminate any suspension of sales it has put into effect and shall take such other
actions to permit registered sales of Registrable Securities as contemplated in this Agreement. 
 (d) Procedures with
Respect to an Underwritten Offering. In the event of any Offering Demand, Enterprise shall enter into an underwriting agreement in customary form with the Managing Underwriter, which shall include, among other provisions, indemnities to the
effect and to the extent provided in Section 2.07, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the registration and disposition of the Registrable Securities.
In connection with any Underwritten Offering under this Section 2.01, a majority of the Selling Holders shall be entitled to select the Managing Underwriter with respect to the Registrable Securities to be sold in that Underwritten Offering. In
connection with an Underwritten Offering under this Section 2.01, each Selling Holder and Enterprise shall be obligated to enter into an underwriting agreement which contains such representations, covenants, indemnities and other rights and
obligations as are customary in underwriting agreements for firm commitment offerings of securities. The Managing Underwriter of the Underwritten Offering shall, no later than the two Business Days prior to the expected date such Underwritten
Offering is expected to be launched (the “Launch Date”), provide to the Selling Holders all of the documentation customarily required for the inclusion of Registrable Securities in the Underwritten Offering, including, without
limitation, a custody agreement and power-of-attorney, underwriting agreement with Selling Holders’ customary representations, warranties, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for
firm commitment offerings of securities, a form of legal opinion required to be delivered by counsel to the Selling Holders (in form and substance reasonably acceptable to counsel for the Selling Holders) at the closing of an Underwritten Offering
and any over-allotment option closing, questionnaires, powers of attorney, indemnities, lock-up agreements (it being understood such agreements shall only contain lock-up provisions that restrict the Selling Holders for a period not exceeding the
duration of the shortest restriction generally imposed by the underwriters on Enterprise or other parties subject to lock-up restrictions in respect of Common Units) and other documents reasonably required under the terms of such underwriting
agreement (collectively, the “Selling Holder Documentation”). No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such
underwriting agreement and, subject to receipt of notice of the Underwritten Offering and Selling Holder Documentation within the time period set forth above: (A) complete its review, return and execute (as applicable) the Selling Holder
Documentation at least one Business Day prior to the expected Launch Date; (B) place the Registrable Securities eligible for inclusion in an Underwritten Offering into the custody of Enterprise’s transfer agent at least one Business Day
prior to the expected Launch Date; (C) agree to participate 

  
 6 








 
following reasonable notice in any due diligence calls arranged by the Managing Underwriter of an Underwritten Offering on the expected Launch Date, the pricing date of an Underwritten Offering
(the “Pricing Date”) or in advance of the closing of an Underwritten Offering and any over-allotment option closing; and (D) unconditionally waive any right to withdraw any Registrable Securities placed into the custody of
Enterprise’s transfer agent for inclusion in an Underwritten Offering within one Business Day of the expected Launch Date, whether on the basis of the offering price, underwriter discount, or for any other reason. Each Selling Holder may, at
its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Enterprise to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or
all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements
with Enterprise or the underwriters other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other
representation required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Enterprise and a Managing Underwriter; provided, however, that such
withdrawal must be made at or prior to the time of pricing of such offering to be effective. No such withdrawal or abandonment shall affect Enterprise’s obligation to pay Registration Expenses. 

(e) Limitation on Demands. Enterprise shall have no obligation to effect in the aggregate, more than (i) five
(5) Demands pursuant to this Section 2.01 less (ii) the number of Demands, if any, as defined and made pursuant to the Registration Rights Agreement, dated as of October 1, 2014, between Enterprise and OTA; provided,
however, that any Shelf Registration Statement (including any post-effective amendment thereto or replacement thereof) shall not be considered a Demand for purposes of this Section 2.01(e); provided further, that any
Underwritten Offering related to a Demand Registration Statement shall only be counted as one Demand. Any Demand shall involve Registrable Securities with a fair market value of at least $225 million. 

(f) Priority With Respect to Holder-Initiated Underwritten Offerings. Notwithstanding anything to the contrary contained
in this Agreement, in connection with an Underwritten Offering contemplated by Section 2.01(a), if any Managing Underwriter of such Underwritten Offering advises Enterprise that the total amount of Common Units that the Selling Holders and any
other Persons intend to include in such Underwritten Offering exceeds the number that can be sold in such Underwritten Offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the
market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Common Units that such Managing Underwriter advises Enterprise can be sold without having such adverse effect, with such
number to be allocated (i) first, pro rata among the Selling Holders, based, for each such Selling Holder, on the percentage derived by dividing (A) the number of Common Units proposed to be sold by such Selling Holder in such Underwritten
Offering; by (B) the aggregate number of Common Units proposed to be 

  
 7 








 
sold by all Selling Holders in the Underwritten Offering; (ii) second, to Enterprise; and (iii) third, pro rata among any other Persons who have been or are granted registration rights
on or after the date of this Agreement who have requested participation in the Underwritten Offering (the “Other Holders”) based, for each such Other Holder, (i) on the percentage derived by dividing (A) the number of
Common Units proposed to be sold by such Other Holders in such Underwritten Offering; by (B) the aggregate number of Common Units proposed to be sold by all Other Holders in the Underwritten Offering or (ii) on such other manner as such
Other Holders may agree. 
 (g) Notification by Holders. Each Selling Holder shall notify Enterprise at such time as
such Selling Holder has sold or otherwise disposed of all of its Registrable Securities. 
 Section 2.02 Registration
Procedures. In connection with its obligations contained in Sections 2.01, Enterprise will, as expeditiously as reasonably practicable: 

(a) prepare and file with the Commission such amendments and supplements to any Registration Statement and the prospectus used
in connection therewith as may be necessary to keep any Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by any Registration Statement; 
 (b) furnish to each Selling Holder (i) as far in advance as reasonably
practicable before filing any registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including furnishing or making
available exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such
Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such registration statement or supplement or amendment
thereto; and (ii) such number of copies of such registration statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other
disposition of the Registrable Securities covered by such registration statement; 
 (c) if applicable, use its commercially
reasonable efforts to register or qualify the Registrable Securities covered by any registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an
Underwritten Offering, the Managing Underwriter, shall reasonably request, provided that Enterprise will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any
action which would subject it to general service of process or taxation in any such jurisdiction where it is not then so subject; 

  
 8 








 (d) promptly notify each Selling Holder and each underwriter, at any time when a
prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of any registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or
any amendment or supplement thereto, and, with respect to such registration statement contemplated by this Agreement, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to
in clause (i) and any written request by the Commission for amendments or supplements to any registration statement contemplated by this Agreement or any prospectus or prospectus supplement thereto; 

(e) immediately notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to
be delivered under the Securities Act, of (i) the occurrence of any event as a result of which the prospectus or prospectus supplement contained in any registration statement contemplated by this Agreement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (ii) the issuance or threat of issuance
by the Commission of any stop order suspending the effectiveness of any registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Enterprise of any notification with
respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Enterprise agrees to as promptly as reasonably
practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings
related thereto; 
 (f) furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with
the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities; 

(g) in the case of an Underwritten Offering, furnish upon request and addressed to the underwriters (i) an opinion of
counsel for Enterprise, dated the effective date of the closing under the underwriting agreement; and (ii) a “comfort letter,” dated the effective date of the applicable registration statement or the date of any amendment of
supplement thereto and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified Enterprise’s financial statements included or
incorporated by reference into the applicable registration statement, and each of the opinion and the “comfort letter” shall be in customary form and covering substantially the same matters with respect to such registration statement (and
the prospectus and any prospectus supplement included therein) and as are customarily covered in opinions of issuers’ counsel and in accountants’ letters delivered to underwriters in underwritten offerings of securities, and such other
matters as such underwriters may reasonably request; 

  
 9 








 (h) otherwise use its commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first
full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

(i) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such
information and Enterprise personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that Enterprise need not disclose any information to any such representative
unless and until such representative has entered into a confidentiality agreement with Enterprise; 
 (j) cause all such
Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Enterprise are then listed; 

(k) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the business and operations of Enterprise to enable the Selling Holders to consummate the disposition of such Registrable Securities; 

(l) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than
the effective date of such registration statement; and 
 (m) enter into customary agreements and take such other actions as
are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities; provided, in no event shall Enterprise be required to cease issuances of Common Units
under any ATM Program pursuant to any lock ups requested by the underwriters. 
 Each Selling Holder, upon receipt of notice from Enterprise of the
occurrence of any event of the kind described in subsection (e) of this Section 2.02, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or
amended prospectus contemplated by subsection (e) of this Section 2.02 or until it is advised in writing by Enterprise that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings
incorporated by reference in the prospectus, and, if so directed by Enterprise, such Selling Holder will, or will request the Managing Underwriter, if any, to deliver to Enterprise (at Enterprise’s expense) all copies in their possession or
control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 

  
 10 








 Section 2.03 Cooperation by Holders. Enterprise shall have no obligation to include
in any Demand Registration units of a Selling Holder who has failed to timely furnish all such information which, in the opinion of counsel to Enterprise, is reasonably required in order for the registration statement or any prospectus or prospectus
supplement thereto, as applicable, to comply with the Securities Act. 
 Section 2.04 Expenses. 

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Enterprise’s
performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Demand Registration, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange
listing and New York Stock Exchange fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, Inc., transfer taxes and fees of
transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for Enterprise, including the expenses of any special audits or “comfort
letters” required by or incident to such performance and compliance. 
 (b) Expenses. Enterprise will pay all
Registration Expenses in connection with any Demand Registration filed pursuant to Section 2.01(a), whether or not the Registration Statement becomes effective or any sale is made pursuant to a Demand Registration. Notwithstanding the
foregoing, except as otherwise provided in Section 2.05, Enterprise shall not be responsible for (i) legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder or (ii) any “Selling
Expenses,” which means all underwriting fees, discounts and selling commissions allocable to the sale of the Registrable Securities. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable
Securities hereunder. 
 Section 2.05 Indemnification. 

(a) By Enterprise. In the event of a registration of any Registrable Securities under the Securities Act pursuant to
this Agreement, Enterprise will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, employees, agents and managers, and each underwriter, pursuant to the applicable underwriting agreement with such underwriter of
Registrable Securities thereunder and each Person, if any, who controls such Selling Holder, and its directors, officers, employees, agents and managers, or underwriter within the meaning of the Securities Act and the Exchange Act, against any
losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, director, officer, underwriter or controlling Person
may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, any free writing prospectus related


  
 11 








 
thereto or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors and officers, each such underwriter and each such
controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Enterprise will not be liable in any such
case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any Selling Holder, any underwriter or
any controlling Person in writing specifically for use in any registration statement contemplated by this Agreement, any prospectus contained therein, any free writing prospectus related thereto or any amendment or supplement thereof, as applicable.
Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer, employee, agent, manager, underwriter or controlling Person, and shall survive the
transfer of such securities by such Selling Holder. 
 (b) By Each Selling Holder. Each Selling Holder agrees
severally and not jointly to indemnify and hold harmless Enterprise, its directors, officers, employees and agents and each Person, if any, who controls Enterprise within the meaning of the Securities Act or of the Exchange Act to the same extent as
the foregoing indemnity from Enterprise to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in any registration statement
contemplated by this Agreement or any prospectus contained therein or any amendment or supplement thereof or any free writing prospectus relating to the Registrable Securities; provided, however, that the liability of each Selling
Holder shall not be greater in amount than the dollar amount of the proceeds received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification. 

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to any indemnified party other than under this Section 2.05. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.05 for any legal expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense


  
 12 








 
and employ counsel or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that
there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the
interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of
such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought
against an indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a
complete and unconditional release from all liability of, the indemnified party. 
 (d) Contribution. If the
indemnification provided for in this Section 2.05 is held by a court or government agency of competent jurisdiction to be unavailable to Enterprise or any Selling Holder in respect of any Losses, then each such indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses as between Enterprise on the one hand and such Selling Holder on the other, in such proportion as is appropriate
to reflect the relative fault of Enterprise on the one hand and of such Selling Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations;
provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds received by such Selling Holder from the sale of Registrable Securities giving rise
to such indemnification. The relative fault of Enterprise on the one hand and each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission
or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable
considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses
reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 
 (e)
Other Indemnification. The provisions of this Section 2.05 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise. 

  
 13 








 Section 2.06 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Enterprise agrees to use its commercially reasonable efforts to: 

(a) make and keep public information regarding Enterprise available, as those terms are understood and defined in Rule 144
under the Securities Act, at all times from and after the date hereof; 
 (b) file with the Commission in a timely manner all
reports and other documents required of Enterprise under the Securities Act and the Exchange Act at all times from and after the date hereof; and 

(c) so long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most
recent annual or quarterly report of Enterprise, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities
without registration. 
 Section 2.07 Transfer or Assignment of Registration Rights. The rights to cause Enterprise to register
Registrable Securities and the other rights granted to M&B by Enterprise under this Article II may not be transferred or assigned, in whole or in part, by M&B other than (a) with the prior written consent of Enterprise (which consent
shall not be unreasonably withheld, conditioned or delayed) or (b) to one or more transferee(s) or assignee(s) of such Registrable Securities that is an Affiliate of M&B and in connection with the transfer of Registrable Securities that, at
the time of such transfer, have a market value of not less than $450 million; provided that (i) Enterprise is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and
identifying the securities with respect to which such registration rights are being transferred or assigned and (ii) each such transferee agrees to be bound by the terms of this Agreement. 

Section 2.08 Information by Holder. Any Holder or Holders of Registrable Securities included in any registration shall promptly
furnish to Enterprise all such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as Enterprise may reasonably request and as shall be required in connection with any registration, qualification or
compliance referred to herein. 
 Section 2.09 Limitations on Subsequent Registration Rights. From and after the date of this
Agreement, Enterprise shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of Enterprise that
contains priority rights with respect to the registration or resale of such securities that contravene the rights of the Holders under this Article II; provided that this limitation shall not apply to any additional Person who becomes a party
to this Agreement in accordance with Section 2.07.

like occurring after the date of this Agreement.

jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity which such party may have.

regard to principles of conflict of laws. 
 Section 3.08 Severability of Provisions. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or
enforceability of such provision in any other jurisdiction. 
 Section 3.09 Entire Agreement. This Agreement is intended by the
parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth

subject matter.

Enterprise and the Holders of a majority of the then outstanding Registrable Securities. 
 Section 3.11 No Presumption. In the
event any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a
particular party or its counsel. 
 Section 3.12 Third-Party Beneficiaries. Nothing in this Agreement shall confer upon any
