limited liability company, as the case may be, and is in good standing in each jurisdiction where the ownership or lease of its Properties or the conduct of its business requires such qualification, except for any failures to be so qualified and in

 15 








 Section 3.04 DM SEC Documents. Since January 1, 2016, the Partnership’s forms,
registration statements, reports, schedules and statements required to be filed by it under the Exchange Act have been filed with the Commission on a timely basis. The DM SEC Documents, at the time filed (or in the case of registration statements,
solely on the dates of effectiveness), except to the extent corrected by a subsequent DM SEC Document, (a) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they were made in the case of any such documents other than a registration statement, not misleading and (b) complied as to form in all material respects with the applicable
requirements of the Exchange Act and the Securities Act, as the case may be. 
 Section 3.05 Financial Statements. 

(a) The historical financial statements (including the related notes and supporting schedule) contained or incorporated by reference in the DM
SEC Documents, (i) comply as to form in all material respects with the applicable accounting requirements under the Securities Act and the Exchange Act (except that certain supporting schedules are omitted), (ii) present fairly in all
material respects the financial position, results of operations and cash flows of the entities purported to be shown thereby on the basis stated therein at the respective dates or for the respective periods and (iii) have been prepared in
accordance with GAAP consistently applied throughout the periods involved, in each case except to the extent disclosed therein. The other financial information of the Partnership Entities, including non-GAAP financial measures, if any, contained or
incorporated by reference in the DM SEC Documents has been derived from the accounting records of the Partnership Entities, and fairly presents in all material respects the information purported to be shown thereby. Nothing has come to the attention
of the Partnership that has caused it to believe that the statistical and market-related data included in the DM SEC Documents is not based on or derived from sources that are reliable and accurate in all material respects as of the date on which
the applicable DM SEC Documents were filed. 
 (b) Since the date of the most recent balance sheet of the Partnership audited by the
Partnership’s auditor, (i) the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the DM SEC Documents fairly presents the information called for in all material respects and has been prepared in
accordance with the Commission’s rules and guidelines applicable thereto in all material respects and (ii) based on an annual evaluation of disclosure controls and procedures, the Partnership is not aware of (A) any significant deficiencies in
the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect the ability of the Partnership to record, process, summarize and report financial information, or any material weaknesses in
internal controls over financial reporting of the Partnership or (B) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls over financial reporting of the Partnership.

 Section 3.06 Independent Registered Public Accounting Firm. Deloitte & Touche LLP, which has audited the financial
statements contained or incorporated by reference in the DM SEC Documents, is an independent registered public accounting firm with respect to the Partnership and the General Partner within the meaning of the Securities Act and the applicable 

  
 16 








 
rules and regulations thereunder adopted by the Commission and the Public Company Accounting Oversight Board (United States). Deloitte & Touche LLP has not resigned or been dismissed as
independent registered public accountants of the Partnership as a result of or in connection with any disagreement with the Partnership or any matter of accounting principles or practices, financial statement disclosure or auditing scope or
procedure. 
 Section 3.07 No Material Adverse Change. Since December 31, 2015, except as described in the DM SEC Documents,
there has not been any Material Adverse Effect. 
 Section 3.08 No Registration Required. Assuming the accuracy of the
representations and warranties of the applicable Purchaser contained in Article IV, the issuance and sale of the Purchased Units to such Purchaser pursuant to this Agreement is exempt from registration requirements of the Securities Act, and
neither the Partnership nor, to the Partnership’s Knowledge, any Person acting on its behalf, has taken nor will take any action hereafter that would cause the loss of such exemption. 

Section 3.09 No Restrictions or Registration Rights. Except as described in the Partnership Agreement, there are no restrictions
upon the voting or transfer of, any equity securities of the Partnership. Except for such rights that have been waived or as expressly set forth in the Registration Rights Agreement, neither the offering or sale of the Purchased Units as
contemplated by this Agreement gives rise to any rights for or relating to the registration of any Purchased Units or other securities of the Partnership. Except as described in the Partnership Agreement, the Partnership has not granted registration
rights to any Person other than the Purchasers that would provide such Person priority over the Purchasers’ rights with respect to any Piggyback Registration. 

Section 3.10 Litigation. Except as described in the DM SEC Documents, there are no actions, suits, claims, investigations,
orders, injunctions or proceedings pending or, to the Knowledge of the Dominion Parties, threatened or contemplated, to which the Partnership Entities or any of their respective directors or officers is or would be a party or to which any of their
respective Properties is or would be subject at law or in equity, before or by any Governmental Authority, or before or by any self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the NYSE),
which would, individually or in the aggregate, if resolved adversely to any Partnership Entity, constitute a Material Adverse Effect, or which challenge the validity of any of the Transaction Documents or the right of either of the Partnership or
the General Partner to enter into any of the Transaction Documents or to consummate the transactions contemplated thereby. 
 Section
3.11 No Default. No Partnership Entity is in breach or violation of or in default under (nor has any event occurred which, with notice, lapse of time or both, would result in any breach or violation of, constitute a default under or give

Contract to which it is a party or by which it or any of its Properties may be bound or affected, (c) any Law, (d) any rule or regulation of any self-regulatory organization or other non-governmental regulatory authority (including,
without limitation, the rules and regulations of the NYSE), or (e) any decree, judgment or order applicable to it or any of its Properties, except in 

  
 17 








 
the case of clauses (b) through (e) for any such breaches, violations or defaults that are described in the DM SEC Documents or that would not, individually or in the aggregate,
constitute a Material Adverse Effect. 
 Section 3.12 No Conflicts. The issuance and sale by the Partnership of the Purchased
Units, the application of the proceeds thereof, the execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated thereby will not conflict with, result in any breach or violation of,

behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under), or result in the creation or imposition of a Lien on any Property or assets of any Partnership Entity pursuant to (a) the
Organizational Documents of any of the Partnership Entities, (b) any Contract to which any of the Partnership Entities is a party or by which any of the Partnership Entities or any of their respective Properties may be bound or affected,

applicable to any of the Partnership Entities or any of their respective properties, except in the cases of clauses (b) through (e) for any such conflicts, breaches, violations or defaults that would not, individually or in the aggregate,
constitute a Material Adverse Effect. 
 Section 3.13 Authority: Enforceability. The Partnership has all requisite power and
authority under the Partnership Agreement and the Delaware LP Act to issue, sell and deliver the Purchased Units, in accordance with and upon the terms and conditions set forth in this Agreement and the Partnership Agreement. All limited partnership
and limited liability company action, as the case may be, required to be taken by the Partnership Entities or any of their partners or members for the authorization, issuance, sale and delivery of the Purchased Units, the execution and delivery of
the Transaction Documents and the consummation of the transactions contemplated thereby shall have been validly taken. No approval from the holders of outstanding Common Units is required under the Partnership Agreement or the rules of the NYSE in
connection with the Partnership’s issuance and sale of the Purchased Units to the Purchasers. Each of the Transaction Documents has been duly and validly authorized and has been or, with respect to the Transaction Documents to be delivered at
the Closing, will be, validly executed and delivered by the Partnership or the General Partner, as the case may be, and, to the Knowledge of the Dominion Parties, the other parties thereto. Each of the Transaction Documents constitutes, or will
constitute, the legal, valid and binding obligations of the Partnership or the General Partner, as the case may be, and, to the Knowledge of the Dominion Parties, each of the parties thereto, in each case enforceable in accordance with its terms;
provided that, with respect to each such agreement, the enforceability thereof may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar Laws from time to time in effect affecting
creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law). 

Section 3.14 Approvals. No approval, authorization, consent, waiver, license, qualification, written exemption from, or order of

Partnership Entity any loans or advances or from transferring any property or assets to the Partnership or any other Partnership Entity, except (a) pursuant to the Term Loan Agreement and the Organizational Documents of Dominion Cove Point LNG, LP,

of formation, with all necessary power and authority to own properties and to conduct its business as currently conducted. 
 Section
4.02 Authorization, Enforceability. Such Purchaser has all necessary legal power and authority to enter into, deliver and perform its obligations under the Transaction Documents to which it is a party. The execution, delivery and

Purchaser is required. Each of the Transaction Documents to which such Purchaser is a party has been duly executed and delivered by such Purchaser, where applicable, and constitutes a legal, valid and binding obligation of such Purchaser;
provided that, with respect to each such agreement, the enforceability thereof may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar Laws from time to time in effect affecting
creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law). 

Section 4.03 No Breach. The execution, delivery and performance of the Transaction Documents to which such Purchaser is a party
by such Purchaser and the consummation by such Purchaser of the transactions contemplated thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material
agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the property or assets of such Purchaser is subject, (b) conflict with or result in any violation of the provisions of the Organizational Documents
of such Purchaser, or (c) violate any 

  
 24 








 
Law of any Governmental Authority or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the case of clauses (a) and (c), for such
conflicts, breaches, violations or defaults as would not prevent the consummation of the transactions contemplated by such Transaction Documents. 

Section 4.04 Certain Fees. No fees or commissions are or will be payable by such Purchaser to brokers, finders or investment
bankers with respect to the purchase of any of the Purchased Units or the consummation of the transactions contemplated by this Agreement or by the Contribution Agreement, except for fees or commissions for which the Partnership is not responsible.
Such Purchaser agrees that it will indemnify and hold harmless the Partnership from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by such Purchaser
or alleged to have been incurred by such Purchaser in connection with the purchase of the Purchased Units or the consummation of the transactions contemplated by this Agreement or by the Contribution Agreement. 

Section 4.05 Unregistered Securities. 

(a) Accredited Investor Status; Sophisticated Purchaser. Such Purchaser is an “accredited investor” within the meaning of
Rule 501 under the Securities Act and is able to bear the risk of its investment in the Purchased Units, the PIK Units and the Conversion Units, as applicable. Such Purchaser has such knowledge and experience in financial and business matters that
it is capable of evaluating the merits and risks of the purchase of the Purchased Units and the Conversion Units, as applicable. 
 (b)
Information. Such Purchaser and its Representatives have been furnished with all materials relating to the business, finances and operations of the Partnership that have been requested and materials relating to the offer and sale of the
Purchased Units and Conversion Units that have been requested by such Purchaser. Such Purchaser and its Representatives have been afforded the opportunity to ask questions of the Partnership. Neither such inquiries nor any other due diligence
investigations conducted at any time by such Purchasers and its Representatives shall modify, amend or affect such Purchasers’ right (i) to rely on the Partnership’s representations and warranties contained in Article III above or
(ii) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in any Transaction Document. Such Purchaser understands that its
purchase of the Purchased Units involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased
Units. 
 (c) Residency. Such Purchaser shall cooperate reasonably with the Partnership to provide any information necessary for any
applicable securities filings. 
 (d) Legends. Such Purchaser understands that, until such time as the Purchased Units, the PIK Units
and the Conversion Units, as applicable, have been sold pursuant to an effective registration statement under the Securities Act, or the Purchased Units are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any
restriction as to the number of securities as of a particular date that can then be immediately sold, the Purchased Units will bear a restrictive legend as provided in the Partnership Agreement. 

  
 25 








 (e) Purchase Representation. Such Purchaser is purchasing the Purchased Units for its own
account and not with a view to distribution in violation of any securities laws. Such Purchaser has been advised and understands that neither the Purchased Units, the PIK Units nor the Conversion Units have been registered under the Securities Act
or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities Act or pursuant
to another available exemption from the registration requirements of the Securities Act). Such Purchaser has been advised and understands that the Partnership, in issuing the Purchased Units, is relying upon, among other things, the representations
and warranties of such Purchaser contained in this Article IV in concluding that such issuance is a “private offering” and is exempt from the registration provisions of the Securities Act. 

(f) Rule 144. Such Purchaser understands that there is no public trading market for the Series A Preferred Units or the PIK Units, that

from registration is available. Such Purchaser has been advised of and is aware of the provisions of Rule 144 promulgated under the Securities Act. 

(g) Reliance by the Partnership. Such Purchaser understands that the Purchased Units are being offered and sold in reliance on a
transactional exemption from the registration requirements of federal and state securities Laws and that the Partnership is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of
such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Purchased Units and the PIK Units, and the Conversion Units issuable upon conversion thereof.

contracted to sell, sold any option or contract to purchase, purchased any option or contract to sell, granted any option, right or warrant to purchase, lent, or otherwise transferred or disposed of, directly or indirectly, any of the Purchased
Units or (b) directly or indirectly engaged in any short sales or other derivative or hedging transactions with respect to the Purchased Units, including by means of any swap or other transaction or arrangement that transfers or that is designed to,
or that might reasonably be expected to, result in the transfer to another, in whole or in part, of any of the economic consequences of ownership of any Purchased Units, regardless of whether any transaction described in this Section 4.07 is
to be settled by delivery of Series A Preferred Units, Common Units or other securities, in cash or otherwise. 

  
 26 








 ARTICLE V. 

COVENANTS 
 Section 5.01
Conduct of Business. During the period commencing on the date of this Agreement and ending on the Closing Date, each of the Partnership Entities will use commercially reasonable efforts to conduct its business in the ordinary course of
business (other than as contemplated by the Contribution Agreement), preserve intact its existence and business organization, Permits, goodwill and present business relationships with all material customers, suppliers, licensors, distributors and
others having significant business relationships with the Partnership Entities (or any of them), to the extent the Partnership believes in its sole discretion that such relationships are and continue to be beneficial to the Partnership Entities and
their businesses; provided, however, that during such period, the Partnership shall provide reasonably prompt written notice to the Purchasers regarding any material adverse developments in respect of the foregoing. Prior to the Closing,
none of the Partnership Entities will modify, amend or waive in any material respect any provision of the Partnership Agreement or the Contribution Agreement that is material to (a) the rights of the Partnership or (b) the rights of the Purchasers,
in their capacity as purchasers of the applicable Purchased Units, in each case, without the prior written consent of the Purchasers possessing the right to acquire not less than a majority of the Purchased Units. 

Section 5.02 Listing of Units. Prior to the Closing, the Partnership will use its commercially reasonable efforts to obtain
approval for listing, subject to notice of issuance, of the Purchased Common Units and the Conversion Units on the NYSE.
 Section 5.03
Cooperation; Further Assurances. Each of the Partnership and the Purchasers shall use its respective commercially reasonable efforts to obtain all approvals and consents required by or necessary to consummate the transactions contemplated
by this Agreement and the other Transaction Documents. Each of the Partnership and the Purchasers agrees to execute and deliver all such documents or instruments, to take all commercially reasonable action and to do all other commercially reasonable
things it determines to be necessary, proper or advisable under applicable Laws and regulations or as otherwise reasonably requested by the other to consummate the transactions contemplated by this Agreement. 

Section 5.04 Lock-up Agreement. Without the prior written consent of the Partnership, except as specifically provided in this
Agreement or as otherwise provided in the Partnership Agreement, each Purchaser of Purchased Preferred Units and its Affiliates shall not, (a) during the period commencing on the Closing Date and ending on the first anniversary of the Closing 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 the Purchased
Preferred Units, (b) during the period commencing on the date hereof and ending on the second anniversary of the Closing Date, directly or indirectly engage in any short sales or other derivative or hedging transactions with respect to the Purchased
Preferred Units or Common Units of the Partnership that are designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Purchased Preferred Units,
(c) transfer any Purchased Preferred Units to any non-U.S. resident individual, non-U.S. corporation or partnership, or any other non-U.S. entity, including any foreign governmental entity, including 

  
 27 








 
by means of any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, of
any of the economic consequences of ownership of any Purchased Preferred Units, regardless of whether any transaction described above is to be settled by delivery of Series A Preferred Units, Common Units or other securities, in cash or otherwise
(provided, however, that the foregoing shall not apply if, prior to any such transfer or arrangement, such individual, corporation, partnership or other entity establishes to the satisfaction of the Partnership, its entitlement to a complete
exemption from tax withholding, including under Code Sections 1441, 1442, 1445 and 1471 through 1474, and the Treasury regulations thereunder), or (d) effect any transfer of Purchased Preferred Units or Conversion Units in a manner that violates the
terms of the Partnership Agreement; provided, however, that such Purchaser may pledge all or any portion of its Purchased Preferred Units to any holders of obligations owed by the Purchaser, including to the trustee for, or
Representative of, such holders, and any such pledge, and any foreclosure by the pledge thereupon, shall not be considered a breach of this Section 5.04; provided, further, that such Purchaser may transfer any Purchased Preferred Units
to (i) an Affiliate of such Purchaser or (ii) any other Purchaser. Notwithstanding the foregoing, any transferee receiving any Purchased Preferred Units pursuant to this Section 5.04 shall (A) agree to the restrictions set forth in this Section 5.04
and (B) to the extent still applicable, take all actions necessary to become a party to the Confidentiality Agreement between the transferee of such Purchased Preferred Units and the Partnership. For the avoidance of doubt, in no way does this
Section 5.04 prohibit changes in the composition of any Purchaser or its partners or members so long as such changes in composition only relate to changes in direct or indirect ownership of the or its partners or members so long as such changes in
composition only relate to changes in direct or indirect ownership of the Purchaser among such Purchaser, its Affiliates and the limited partners of the private equity fund vehicles that indirectly own such Purchaser. After the first
anniversary of the Closing Date, the Purchasers or other holders of Purchased Preferred Units may only transfer Purchased Preferred Units involving an underlying value of Common Units in an amount not less than $50 million based on the closing
trading price of Common Units on the date immediately preceding such transfer on the NYSE or other National Securities Exchange on which the Common Units are then listed for trading (or such lesser amount if it (x) constitutes the remaining holdings
of the Purchaser or holder or (y) has been approved by the General Partner, in its sole discretion), subject to compliance with applicable securities Laws and the Partnership Agreement; provided, however, that the provisions of this sentence
shall not eliminate, modify or reduce the obligations set forth in clauses (b), (c), or (d) above. For the avoidance of doubt, nothing in this Section 5.04 shall restrict the Purchasers of Purchased Common Units from taking any action with respect
to such Purchaser’s Purchased Common Units. 
 Section 5.05 Tax Estimates. On or before April 1 of each year
beginning in 2019, the Partnership shall provide each Purchaser a good faith estimate (and reasonable supporting calculations) of whether there was sufficient Unrealized Gain attributable to the Partnership property as of December 31 of the
previous year such that, if any of such Purchaser’s Series A Preferred Units were converted to Common Units and such Unrealized Gain was allocated to such Purchaser pursuant to Section 6.1(d)(xiii) of the Second A&R LPA (taking proper
account of allocations of higher priority), such Purchaser’s Capital Account in respect of its Common Units would be equal to the Per Unit Capital Amount for an Initial Common Unit without any need for corrective allocations under Section
6.2(h) of the Second A&R LPA. In addition, on 

  
 28 








 
and after the first date on which the Series A Preferred Units are convertible pursuant to Section 5.11(b)(vi)(A) of the Second A&R LPA, following receipt of a written request from any
Purchaser that, together with its Affiliates, acquired $100 million or more Purchased Preferred Units on the Closing Date, so long as such Purchaser or any of its respective Affiliates continues to own Purchased Preferred Units, the Partnership
shall provide such Purchaser with a good faith estimate (and reasonable supporting calculations) of whether there is sufficient Unrealized Gain attributable to the Partnership property on the date of such request such that, if any of the
Purchaser’s Series A Preferred Units were converted to Common Units and such Unrealized Gain was allocated to such Purchaser pursuant to Section 6.1(d)(xiii) of the Second A&R LPA (taking proper account of allocations of higher priority),
such Purchaser’s Capital Account in respect of its Common Units would be equal to the Per Unit Capital Amount for an Initial Common Unit without any need for corrective allocations under Section 6.2(h) of the Second A&R LPA. Each such
Purchaser, together with its Affiliates, shall be entitled to make such a request not more than once per calendar year. 
 For purposes of
this Section 5.05, all capitalized terms used but not defined herein shall have the meanings assigned to them in the Second A&R LPA. 

Section 5.06 Use of Proceeds. The Partnership shall use the proceeds of the offering of the Purchased Units to repay
indebtedness of the Partnership, to redeem Common Units, to acquire assets as contemplated by the Contribution Agreement or for general partnership purposes. 

ARTICLE VI.

(collectively, “Purchaser Related Parties”) from costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, and hold each of them harmless against, any and all actions, suits, proceedings (including any
investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever
(including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any
of them), whether or not involving a Third-Party Claim, as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by the Partnership contained herein to be true and correct in all
material respects (other than those representations and warranties contained in Section 3.01, Section 3.02, Section 3.03, Section 3.13, Section 3.16 or Section 3.18 or other representations and warranties
that are qualified by materiality or Material Adverse Effect, which, in each case, shall be true and correct in all respects) when made and as of the Closing Date (except for any representations and warranties made as of a specific date, which shall
be required to be true and correct as of such date only) or (b) the breach of any covenants of the Partnership contained herein; provided that, in the case of the immediately preceding clause (a), such claim for indemnification is made
prior to the expiration of the survival period of such representation or warranty; provided, further, that for purposes of determining when an indemnification claim has been made, the date upon which 

  
 29 








 
a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Partnership shall constitute the date upon which such claim has
been made; and provided, further, that the aggregate liability of the Partnership to each Purchaser pursuant to this Section 6.01 shall not be greater in amount than such Purchaser’s Funding Obligation, and the aggregate
liability of the Partnership to all Purchasers pursuant to this Section 6.01 shall not exceed the Total Funding Obligation. No Purchaser Related Party shall be entitled to recover special, indirect, exemplary, lost profits, speculative or
punitive damages under this Section 6.01; provided, however, that such limitation shall not prevent any Purchaser Related Party from recovering under this Section 6.01 for any such damages to the extent that such damages are in
the form of diminution in value or are payable to a third party in connection with any Third-Party Claims. 
 Section 6.02
Indemnification by the Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify the Partnership, the General Partner and their respective Representatives (collectively, “Partnership Related
Parties”) from, costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries),
demands, and causes of action, and, in connection therewith, promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever (including the reasonable fees and
disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving
a Third-Party Claim, as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by such Purchaser contained herein to be true and correct in all material respects as of the date made
(except to the extent any representation or warranty includes the word “material,” Material Adverse Effect or words of similar import, with respect to which such representation or warranty, or applicable portions thereof, must have been
true and correct) or (b) the breach of any of the covenants of such Purchaser contained herein; provided that, in the case of the immediately preceding clause (a), such claim for indemnification relating to a breach of any
representation or warranty is made prior to the expiration of the survival period of such representation or warranty; and provided, further, that for purposes of determining when an indemnification claim has been made, the date upon which a
Partnership Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to such Purchaser shall constitute the date upon which such claim has been made; and provided, further, that the
liability of each such Purchaser shall not be greater in amount than the sum of such Purchaser’s Funding Obligation plus any distributions paid to such Purchaser with respect to the Purchased Units. No Partnership Related Party shall be
entitled to recover special, indirect, exemplary, lost profits, speculative or punitive damages under this Section 6.02; provided, however, that such limitation shall not prevent any Partnership Related Party from recovering under this
Section 6.02 for any such damages to the extent that such damages are in the form of diminution in value or are payable to a third party in connection with any Third-Party Claims. 

Section 6.03 Indemnification Procedure. 

(a) A claim for indemnification for any matter not involving a Third-Party Claim may be asserted by notice to the party from whom
indemnification is sought; provided,  

  
 30 








 
however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article VI,
except as otherwise provided in Section 6.01 and Section 6.02. 
 (b) Promptly after any Partnership Related Party or
Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party
believes in good faith is an indemnifiable claim under this Agreement (each a “Third-Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written
notice of such Third-Party Claim, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is
materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third-Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel
who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly, and in no
event later than 10 days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or
control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted
liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has,
within 10 Business Days of when the Indemnified Party provides written notice of a Third-Party Claim, failed (1) to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (2) to notify the Indemnified Party of such
assumption or (B) 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 in addition 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 expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed
by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no
liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party. 

  
 31 








 Section 6.04 Tax Matters. All indemnification payments under this Article VI
shall be adjustments to the applicable Purchaser’s Funding Obligation except as otherwise required by applicable Law. 
 ARTICLE VII.

 TERMINATION 

Section 7.01 Termination. This Agreement may be terminated at any time prior to the Closing: 

(a) by mutual written consent of the Partnership and a Purchaser, with respect to itself but not any other Purchaser; 

(b) by written notice from either the Partnership or a Purchaser, with respect to itself but not any other Purchaser, if any Governmental
Authority with lawful jurisdiction shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated by the Transaction Documents and such order, decree,
ruling or other action is or shall have become final and nonappealable; 
 (c) by written notice from either the Partnership or a Purchaser,
with respect to itself but not any other Purchaser, if the Contribution Agreement is terminated for any reason; or 
 (d) by written notice
from a Purchaser, with respect to itself but not any other Purchaser, if the Closing does not occur by 11:59 p.m. on the Drop-Dead Date; provided, however, that no party may terminate this Agreement pursuant to this Section 7.01(d) if
such party is, at the time of providing such written notice, in breach of any of its obligations under this Agreement. 
 Section 7.02
Certain Effects of Termination. In the event that this Agreement is terminated pursuant to Section 7.01: 
 (a) except as
set forth in Section 7.02(b), this Agreement shall become null and void and have no further force or effect, but the parties shall not be released from any liability arising from or in connection with any breach hereof occurring prior to such
termination; 
 (b) regardless of any purported termination of this Agreement, the provisions of Article VI and all indemnification
rights and obligations of the Partnership and the Purchasers thereunder, this Section 7.02 and the provisions of Article VIII shall remain operative and in full force and effect as between the Partnership and the Purchasers, unless the
Partnership and the Purchasers possessing the right to acquire not less than majority of the Purchased Units execute a writing that expressly (with specific references to the applicable Articles, Sections or subsections of this Agreement) terminates
such rights and obligations as between the Partnership and the Purchasers; and 
 (c) each of the Confidentiality Agreements shall remain in
effect in accordance with Section 8.06(a). 

  
 32 








 ARTICLE VIII. 

MISCELLANEOUS 
 Section
8.01 Expenses. Except as set forth below, all costs and expenses, including fees and disbursements of counsel, financial advisors and accountants, incurred in connection with the Transaction Documents and the transactions contemplated
thereby shall be paid by the party incurring such costs and expenses; provided that promptly following receipt of an invoice therefore containing reasonable supporting detail, the Partnership shall reimburse Stonepeak for the reasonable fees
and expenses of Sidley Austin LLP, counsel to Stonepeak, of up to $300,000 (with legal fees and expenses of Sidley Austin LLP in excess of $300,000 to be paid pro rata by all the Purchasers in proportion to the aggregate number of Purchased Units
purchased by each). 
 Section 8.02 Interpretation. Article, Section, Schedule and Exhibit references in this Agreement are
references to the corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are
an integral part of this Agreement. All references to instruments, documents, Contracts and agreements are references to such instruments, documents, Contracts and agreements as the same may be amended, supplemented and otherwise modified from time
to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately
following it. Whenever the Partnership has an obligation under the Transaction Documents, the expense of complying with that obligation shall be an expense of the Partnership unless otherwise specified. Any reference in this Agreement to
“$” shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by a Purchaser, such action shall be in such Purchaser’s sole discretion, unless otherwise specified in this Agreement. If any
provision in the Transaction Documents is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and the Transaction Documents shall be construed and enforced as if such illegal, invalid, not binding
or unenforceable provision had never comprised a part of the Transaction Documents, and the remaining provisions shall remain in full force and effect, and (b) the parties hereto shall negotiate in good faith to modify the Transaction Documents so
as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period
of time before which, within which or following which any act is to be done or step taken pursuant to the Transaction Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is not
a Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,”
“hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement
into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. 

Section 8.03 Survival of Provisions. The representations and warranties set forth in Section 3.01, Section 3.02,
Section 3.03, Section 3.13, Section 3.16, Section 3.18, Section 4.01, Section 4.02, Section 4.04, Section 4.05(a), Section 4.05(b) and Section 4.05(e) hereunder shall 

  
 33 








 
survive the execution and delivery of this Agreement indefinitely, the representations and warranties set forth in Section 3.27 shall survive until 60 days after the applicable statute of
limitations (taking into account any extensions thereof) and the other representations and warranties set forth herein shall survive for a period of 12 months following the Closing Date, regardless of any investigation made by or on behalf of the
Partnership or the Purchasers. The covenants made in this Agreement or any other Transaction Document shall survive the Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment
therefor and repayment, conversion or repurchase thereof. Regardless of any purported general termination of this Agreement, the provisions of Article VI and all indemnification rights and obligations of the Partnership and the Purchasers
thereunder, and this Article VIII shall remain operative and in full force and effect as between the Partnership and each Purchaser, unless the Partnership and the applicable Purchaser execute a writing that expressly (with specific
references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between the Partnership and such Purchaser. 

Section 8.04 No Waiver: Modifications in Writing. 

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not
exclusive of any remedies that may be available to a party at law or in equity or otherwise. 
 (b) Specific Waiver. Except as
otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of any Transaction Document (except in the case of the Partnership Agreement for amendments adopted pursuant to Article XIII thereof) shall be
effective unless signed by each of the parties thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of any Transaction Document, any waiver of any
provision of any Transaction Document and any consent to any departure by the Partnership from the terms of any provision of any Transaction Document shall be effective only in the specific instance and for the specific purpose for which made or
given. Except where notice is specifically required by this Agreement, no notice to or demand on the Partnership in any case shall entitle the Partnership to any other or further notice or demand in similar or other circumstances. Any investigation
by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. 

Section 8.05 Binding Effect. This Agreement shall be binding upon the Partnership, each of the Purchasers and their respective
successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and
permitted assigns. 
 Section 8.06 Non-Disclosure. 

(a) This Agreement shall not impact the terms and provisions of any of the Confidentiality Agreements. The Confidentiality Agreements shall
continue to be in full force and effect, pursuant to the terms and conditions thereof, but for the avoidance of doubt, Confidential Information (as defined in each of the Confidentiality Agreements) only refers to information furnished by or on
behalf of the Company prior to the date hereof. 

  
 34 








 (b) Other than filings made by the Partnership with the Commission, the Partnership and any of
its Representatives may disclose the identity of, or any other information concerning, the Purchasers or any of their respective Affiliates only after providing the Purchasers a reasonable opportunity to review and comment on such disclosure (with
such comments being incorporated or reflected, to the extent reasonable, in any such disclosure); provided, however, that nothing in this Section 8.06 shall delay any required filing or other disclosure with the NYSE or any
Governmental Authority or otherwise hinder the Partnership Entities’ or their Representatives’ ability to timely comply with all Laws or rules and regulations of the NYSE or other Governmental Authority. 

(c) Notwithstanding anything to the contrary in this Section 8.06, the Partnership and the General Partner agree that each Purchaser
may (i) publicize its ownership in the Partnership, as well as the identity of the Partnership, the size of the investment and its pricing terms with respect to the Series A Preferred Units on its internet site or in marketing materials, press
releases, published “tombstone” announcements or any other print or electronic medium and (ii) display the Partnership’s corporate logo in conjunction with any such reference. 

Section 8.07 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by registered
or certified mail, return receipt requested, telecopy, electronic mail, air courier guaranteeing overnight delivery or personal delivery to the following addresses

 or to such other address as the Partnership or the Purchasers may designate in writing. All notices and
communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; upon actual receipt if sent by certified or registered mail, return receipt requested, or regular mail, if mailed; upon actual receipt of
the facsimile, if sent via facsimile; when sent, if sent by electronic mail prior to 5:00 pm Houston, Texas time on a Business Day, or on the next succeeding Business Day, if not; and upon actual receipt when delivered to an air courier guaranteeing

 Section 8.08 Removal of Legend. In connection with a sale of Purchased Units, PIK Units or Conversion
Units by a Purchaser in reliance on Rule 144 promulgated under the Securities Act, the applicable Purchaser or its broker shall deliver to the Partnership a broker representation letter providing to the Partnership any information the Partnership
deems necessary to determine that the sale of such Purchased Units, PIK Units or Conversion Units is made in compliance with Rule 144 promulgated under the Securities Act, including, as may be appropriate, a certification that the Purchaser is not
an Affiliate of the Partnership (as defined in Rule 144 promulgated under the Securities Act) and a certification as to the length of time the such units have been held. Upon receipt of such representation letter, the Partnership shall promptly
remove the notation of a restrictive legend in such Purchaser’s book-entry account maintained by the Partnership, including the legend referred to in Section 4.05, and the Partnership shall bear all costs associated with the removal of
such legend in the Partnership’s books. At such time as the Purchased Units, PIK Units or Conversion Units have been sold pursuant to an effective registration statement under the Securities Act or have been held by any Purchaser for more than
one year where such Purchaser is not, and has not been in the preceding three months, an affiliate of the Partnership (as defined in Rule 144 promulgated under the Securities Act), if the book-entry account of such Purchaser still bears the notation
of the restrictive legend referred to in Section 4.05, the Partnership agrees, upon request of the Purchaser or its permitted assignee, to take all steps necessary to promptly effect the removal of the legend described in Section 4.05,
and the Partnership shall bear all costs associated with the removal of such legend in the Partnership’s books, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted
assignee provides to the Partnership any information the Partnership deems reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state Laws, including (if there is no such registration
statement) a certification that the holder is not an Affiliate of the Partnership (as defined in Rule 144 promulgated under the Securities Act), a covenant to inform the Partnership if it should thereafter become an affiliate (as defined in Rule 144
promulgated under the Securities Act) and to consent to the notation of an appropriate restriction, and a certification as to the length of time such units have been held. The Partnership shall cooperate with each Purchaser to effect the removal of
the legend referred to in Section 4.05 at any time such legend is no longer appropriate. 
 Section 8.09 Entire
Agreement. This Agreement, the other Transaction Documents, the Confidentiality Agreements and the other agreements and documents referred to herein are 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 and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or
referred to in this Agreement, the other Transaction Documents or the Confidentiality Agreements with respect to the rights granted by the 

  
 36 








 
Partnership or any of its Affiliates or the Purchasers or any of their respective Affiliates. This Agreement, the other Transaction Documents, the Confidentiality Agreements and the other
agreements and documents referred to herein or therein supersede all prior agreements and understandings among the parties with respect to such subject matter. 

Section 8.10 Governing Law: Submission to Jurisdiction. This Agreement, and all claims or causes of action (whether in contract
or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty
made in or in connection with this Agreement), will be construed in accordance with and governed by the Laws of the State of Delaware without regard to principles of conflicts of laws. Any action against any party relating to the foregoing shall be
brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of
Delaware over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the laying of venue of any such dispute brought in such court or any
defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. 

Section 8.11 Waiver of Jury Trial. THE PARTIES TO THIS AGREEMENT EACH HEREBY WAIVES, AND AGREES TO CAUSE ITS AFFILIATES TO
WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (a) ARISING UNDER THIS AGREEMENT OR (b) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES
HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. THE PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS
THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE
CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 
 Section 8.12 Exclusive Remedy. 

(a) Each party hereto hereby acknowledges and agrees that the rights of each party to consummate the transactions contemplated hereby are
special, unique and of extraordinary character and that, if any party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching party may be without an adequate remedy at law. If any party violates or
fails or refuses to perform any covenant or agreement made by such party herein, the non-breaching party subject to the terms hereof and in addition to any remedy at law for damages or other relief, may (at any time prior to the valid termination of
this Agreement pursuant to Article VII) institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief. 

  
 37 








 (b) The sole and exclusive remedy for any and all claims arising under, out of, or related to
this Agreement or the transactions contemplated hereby, shall be the rights of indemnification set forth in Article VI only, and no Person will have any other entitlement, remedy or recourse, whether in contract, tort or otherwise, it being
agreed that all of such other remedies, entitlements and recourse are expressly waived and released by the parties hereto to the fullest extent permitted by Law. Notwithstanding anything in the foregoing to the contrary, nothing in this Agreement
shall limit or otherwise restrict a fraud claim brought by any party hereto or the right to seek specific performance pursuant to Section 8.12(a). 

Section 8.13 No Recourse Against Others. 

(a) All claims, obligations, liabilities or causes of action (whether in contract or in tort, in law or in equity, or granted by statute) that
may be based upon, in respect of, arise under, out or by reason of, be connected with or relate in any manner to this Agreement, or the negotiation, execution or performance of this Agreement (including any representation or warranty made in, in
connection with, or as an inducement to, this Agreement), may be made only against (and are expressly limited to) the Partnership and the Purchasers. No Person other than the Partnership or the Purchasers, including no member, partner, stockholder,
Affiliate or Representative thereof, nor any member, partner, stockholder, Affiliate or Representative of any of the foregoing, shall have any liability (whether in contract or in tort, in law or in equity, or granted by statute) for any claims,
causes of action, obligations or liabilities arising under, out of, in connection with or related in any manner to this Agreement or based on, in respect of or by reason of this Agreement or its negotiation, execution, performance or breach; and, to
the maximum extent permitted by Law, each of the Partnership and the Purchasers hereby waives and releases all such liabilities, claims, causes of action and obligations against any such third Person. 

(b) Without limiting the foregoing, to the maximum extent permitted by Law, (i) each of the Partnership and the Purchasers hereby waives and
releases any and all rights, claims, demands or causes of action that may otherwise be available at law or in equity, or granted by statute, to avoid or disregard the entity form of the other or otherwise impose liability of the other on any third
Person in respect of the transactions contemplated hereby, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness,
undercapitalization or otherwise; and (ii) each of the Partnership and the Purchasers disclaims any reliance upon any third Person with respect to the performance of this Agreement or any representation or warranty made in, in connection with or as
an inducement to this Agreement. 
 Section 8.14 No Third-Party Beneficiaries. Nothing in this Agreement, express or implied,
is intended to or shall confer upon any Person, other than the Partnership, the Purchasers and, for purposes of Section 8.13 only, any member, partner, stockholder, Affiliate or Representative of the Partnership or the Purchasers, or any
member, partner, stockholder, Affiliate or Representative of any of the foregoing, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. 

  
 38 








 Section 8.15 Execution in Counterparts. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one
and the same agreement. 
 Section 8.16 Certain Adjustments. Notwithstanding anything to the contrary in this Agreement, the
Common Unit Offering Price and the Common Unit Signing Price, as applicable and without duplication, shall be proportionately adjusted pursuant to the terms of Section 5.11(b)(vi)(E) of the Second A&R LPA to account for any distributions or
other transactions described in subclauses (i) through (viii) therein that occurred between the date of this Agreement and the Closing Date as if such section were in effect during such period.

 EXHIBIT A 

FORM OF OPINION OF VINSON & ELKINS L.L.P. 

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Series A Preferred Unit and Common Unit Purchase
Agreement (the “Purchase Agreement”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Vinson & Elkins L.L.P., counsel for the Partnership, addressed to the Purchasers and dated the Closing
Date in form satisfactory to the Purchasers, stating that: 
 (i) Each of the Partnership, the General Partner and the subsidiaries of the
Partnership listed on Schedule I hereto (the “Material Subsidiaries”) is validly existing and in good standing under the laws of its jurisdiction of formation. Each of the Partnership, the General Partner and the Material
Subsidiaries has all requisite limited liability company or partnership power and authority, as applicable, under the laws of its jurisdiction of formation necessary to own or lease its properties and to conduct its business, in each case in all
material respects as described in the DM SEC Documents. 
 (ii) Except as have been waived or satisfied or as otherwise described in the
Partnership Agreement, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any Purchased Units or Conversion Units pursuant to the Organizational Documents of the
Partnership or any agreement filed as an exhibit to the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2015 or any Current Report or Quarterly Report filed thereafter to which the Partnership is a party or by which the
Partnership may be bound. 
 (iii) The Purchased Units to be issued and sold to the Purchasers by the Partnership pursuant to the Purchase
Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Purchasers against payment therefor in accordance with the terms of the
Purchase Agreement, will be validly issued in accordance with the terms of the Partnership Agreement, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters
described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act); and, other than the rights granted to the General Partner under Section 5.7 of the Partnership Agreement, the issuance and sale of the Purchased Units are not subject to any
preemptive rights of any securityholder of the Partnership arising under the Delaware LP Act as currently in effect or the Partnership’s Organizational Documents as currently in effect. 

(iv) Assuming the distribution of the PIK Units, if any, is properly authorized by the General Partner and that such PIK Units are issued in
accordance with the terms of the Partnership Agreement, such PIK Units will be duly authorized, validly issued, fully paid (to the extent required by applicable law and the Partnership Agreement) and nonassessable (except as such nonassessability
may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act). 

  
 Exhibit A-1 








 (v) The Conversion Units have been duly authorized by the General Partner on behalf of the
Partnership pursuant to the Partnership Agreement and, when issued upon conversion of the Purchased Units in accordance with the terms of the Partnership Agreement, will be validly issued, fully paid (to the extent required by applicable law and the
Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act); and, other than the rights granted to the General Partner under Section 5.7 of the Partnership
Agreement, the issuance of the Conversion Units are not subject to any preemptive rights of any securityholder of the Partnership arising under the Delaware LP Act as currently in effect or the Partnership’s Organizational Documents as
currently in effect. 
 (vi) No consent, approval, authorization, filing with or order of any federal or Delaware court, Governmental
Authority or body having jurisdiction over the Partnership is required for the issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance by the Partnership of the Transaction Documents, or the consummation
of the transactions contemplated by the Transaction Documents, except (i) as may be required in connection with the Partnership’s obligations under the Registration Rights Agreement to register the resale of the Purchased Units or the
Conversion Units under the Securities Act, (ii) those that have been obtained or made, (iii) as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion, or (iv) such that the failure to obtain
would not reasonably be expected to constitute a Material Adverse Effect. 
 (vii) Assuming the accuracy of the representations and
warranties of the Purchasers and the Partnership contained in the Purchase Agreement, the offer, issuance and sale of the Purchased Units by the Partnership to the Purchasers solely in the manner contemplated by the Purchase Agreement, including the
issuance of the Conversion Units to such Purchasers upon conversion of the Purchased Preferred Units in accordance with the Partnership Agreement (assuming such conversion takes place as of the date hereof), are exempt from the registration
requirements of the Securities Act; provided, however, that no opinion is expressed as to any subsequent sale or resale of the Purchased Units or the Conversion Units. 

(viii) The Partnership is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

 (ix) None of the offering, issuance or sale by the Partnership of the Purchased Units or the execution, delivery and performance of the
Transaction Documents by the Partnership or the General Partner, as the case may be, or the consummation of the transactions contemplated thereby will result in a breach or violation of (A) the Organizational Documents of the Partnership or the
General Partner, as the case may be, (B) any agreement filed as an exhibit to the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2015 or any Current Report or Quarterly Report filed thereafter, or (C) the Delaware LP
Act or U.S. federal law, which in the case of clauses (B) or (C) would be reasonably expected to constitute a Material Adverse Effect; provided, however, that we express no opinion pursuant to this paragraph (viii) with respect to any
securities or other anti-fraud law. 
 (x) Each of the Transaction Documents has been duly authorized and validly executed and delivered by
the Partnership or the General Partner, as the case may be, and 

  
 Exhibit A-2 








 
the Second A&R LPA constitutes a valid and binding obligation of the General Partner, enforceable against such party in accordance with its terms, except insofar as the enforceability thereof
may be limited by (A) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity
(regardless of whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

into by and among Dominion Midstream GP, LLC, a Delaware limited liability company, as the General Partner, together with any other Persons who are or become Partners in the Partnership or parties hereto as provided herein. 

WHEREAS, the General Partner and the other parties thereto entered into that certain First Amended and Restated Agreement of Limited
Partnership of the Partnership dated as of October 20, 2014 (the “2014 Agreement”); and 
 WHEREAS, the
General Partner desires to amend and restate the 2014 Agreement in its entirety to provide for a new class of convertible preferred securities and to provide for such other changes as the General Partner has determined are necessary and appropriate
in connection with the issuance of such securities and/or do not adversely affect the Limited Partners (including any particular class of Partnership Interests as compared to other classes of Partnership Interests) in any material respect. 

NOW, THEREFORE, the General Partner does hereby amend and restate the 2014 Agreement, pursuant to its authority under Section 13.1 of the
2014 Agreement, to provide, in its entirety, as follows: 
 ARTICLE I  

DEFINITIONS 

Section 1.1 Definitions. The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary,
applied to the terms used in this Agreement. 
 “Additional Book Basis” means, with respect to any Adjusted Property, the
portion of the Carrying Value of such Adjusted Property that is attributable to positive adjustments made to such Carrying Value, as determined in accordance with the provisions set forth below in this definition of Additional Book Basis. For
purposes of determining the extent to which Carrying Value constitutes Additional Book Basis: 
 (a) Any negative adjustment made to the
Carrying Value of an Adjusted Property as a result of either a Book-Down Event or a Book-Up Event shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive
adjustments made thereto pursuant to a Book-Up Event or Book-Down Event. 
 (b) If Carrying Value that constitutes Additional Book Basis is
reduced as a result of a Book-Down Event (an “Additional Book Basis Reduction”) and the Carrying Value of other property is increased as a result of such Book-Down Event (a “Carrying Value Increase”),
then any such Carrying Value Increase shall be treated as Additional Book Basis in an amount equal

to the lesser of (a) the amount of such Carrying Value Increase and (b) the amount determined by proportionately allocating the Carrying Value Increases resulting from such Book-Down
Event the lesser of (I) the aggregate Additional Book Basis Reductions resulting from such Book-Down Event and (II) the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceed the remaining Additional
Book Basis attributable to all of the Partnership’s Adjusted Property after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event). 

“Additional Book Basis Derivative Items” means any Book Basis Derivative Items that are computed with reference to
Additional Book Basis. To the extent that the Additional Book Basis attributable to all of the Partnership’s Adjusted Property as of the beginning of any taxable period exceeds the Aggregate Remaining Net Positive Adjustments as of the
beginning of such period (the “Excess Additional Book Basis”), the Additional Book Basis Derivative Items for such period shall be reduced by the amount that bears the same ratio to the amount of Additional Book
Basis Derivative Items determined without regard to this sentence as the Excess Additional Book Basis bears to the Additional Book Basis as of the beginning of such period. With respect to a Disposed of Adjusted Property, the Additional Book Basis
Derivative Items shall be the amount of Additional Book Basis taken into account in computing gain or loss from the disposition of such Disposed of Adjusted Property; provided that the provisions of the immediately preceding sentence shall
apply to the determination of the Additional Book Basis Derivative Items attributable to Disposed of Adjusted Property. 

“Adjusted Capital Account” means, with respect to any Partner, the balance in such Partner’s Capital Account at
the end of each taxable period of the Partnership after giving effect to the following adjustments: 
 (a) Credit to such Capital
Account any amounts which such Partner is (x) obligated to restore under the standards set by Treasury Regulation Section 1.704-1(b)(2)(ii)(c) or (y) deemed obligated to restore pursuant to the penultimate sentences of Treasury
Regulation Sections 1.704-2(g)(1) and 1.704-2(i)(5); and 
 (b) Debit to such Capital Account the items described in Treasury Regulation
Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) and 1.704-1(b)(2)(ii)(d)(6). 
 The foregoing definition of Adjusted Capital
Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. The “Adjusted Capital Account” of a Partner in respect of any Partnership Interest
shall be the amount that such Adjusted Capital Account would be if such Partnership Interest were the only interest in the Partnership held by such Partner from and after the date on which such Partnership Interest was first issued. 

“Adjusted Operating Surplus” means, with respect to any period, (a) Operating Surplus generated with respect to
such period; (b) less (i) the amount of any net increase during such period in Working Capital Borrowings (or, subject to Section 8.1(c), the Partnership’s proportionate share of any net increase in Working Capital Borrowings in
the case of

Subsidiaries that are not wholly owned); (ii) the amount of any net decrease during such period in cash reserves (or, subject to Section 8.1(c), the Partnership’s proportionate
share of any net decrease in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures not relating to an Operating Expenditure made during such period; and (iii) the amount of any expenditures during such
period using the proceeds of the Initial Offering as described under “Use of Proceeds” in the Registration Statement that would constitute Operating Expenditures in the absence of clause (c)(vi) of the definition thereof; and
(iv) capital contributions received by a Group Member (including Capital Contributions received by the Partnership) to the extent such capital contributions do not constitute Interim Capital Transactions; and (c) plus (i) the amount
of any net decrease during such period in Working Capital Borrowings (or, subject to Section 8.1(c), the Partnership’s proportionate share of any net decrease in Working Capital Borrowings in the case of Subsidiaries that are not wholly
owned); (ii) the amount of any net increase during such period in cash reserves (or, subject to Section 8.1(c), the Partnership’s proportionate share of any net increase in cash reserves in the case of Subsidiaries that are not wholly
owned) for Operating Expenditures required by any debt instrument for the repayment of principal, interest or premium; and (iii) the amount of any net decrease made in subsequent periods in cash reserves for Operating Expenditures initially
established during such period to the extent such decrease results in a reduction in Adjusted Operating Surplus in subsequent periods pursuant to clause (b)(ii) above. Adjusted Operating Surplus does not include that portion of Operating Surplus
included in clause (a)(i) of the definition of Operating Surplus. To the extent that disbursements made, cash received or cash reserves established, increased or reduced after the end of a period are included in the determination of Operating
Surplus for such period (as contemplated by the proviso in the definition of “Operating Surplus”) such disbursements, cash receipts and changes in cash reserves shall be deemed to have occurred in such period (and not in any future period)
for purposes of calculating increases or decreases in Working Capital Borrowings or cash reserves during such period. 
 “Adjusted
Property” means any property the Carrying Value of which has been adjusted pursuant to Section 5.4(d).

 Section 4.2 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate officers of the General Partner on
behalf of the Partnership shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Interests as the Certificate so surrendered. 

(b) The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer
Agent shall countersign, a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate: 

(i) makes proof by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate
has been lost, destroyed or stolen; 
 (ii) requests the issuance of a new Certificate before the General Partner has notice
that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim; 

(iii) if requested by the General Partner, delivers to the General Partner a bond, in form and substance satisfactory to the
General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct to indemnify the Partnership, the Partners, the General Partner and the Transfer Agent against any claim that may be made on account of the
alleged loss, destruction or theft of the Certificate; and 
 (iv) satisfies any other reasonable requirements imposed by the
General Partner or the Transfer Agent. 
 If a Limited Partner fails to notify the General Partner within a reasonable period of time after
such Limited Partner has notice of the loss, destruction or theft of a Certificate, and a transfer of the Limited Partner Interests represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent
receives such notification, the Limited Partner shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate. 

(c) As a condition to the issuance of any new Certificate under this Section 4.2, the General Partner may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith. 

Section 4.3 Record Holders. The Partnership and the General Partner shall be entitled to recognize the Record Holder as the
Partner with respect to any Partnership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to, or interest in, such Partnership Interest on the part of any other Person, regardless of whether the Partnership
shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading.
Without limiting the foregoing, when a

Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another
Person in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Persons on the other, such representative Person shall be (a) the Record Holder of such Partnership Interest and (b) bound
by this Agreement and shall have the rights and obligations of a Partner hereunder as, and to the extent, provided herein. 

Section 4.4 Transfer Generally. 

(a) The term “transfer,” when used in this Agreement with respect to a Partnership Interest, shall mean
a transaction by which the holder of a Partnership Interest assigns such Partnership Interest to another Person who is or becomes a Partner, and includes a sale, assignment, gift, exchange or any other disposition by law or otherwise, excluding a
pledge, encumbrance, hypothecation or mortgage but including any transfer upon foreclosure of any pledge, encumbrance, hypothecation or mortgage. 

(b) No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set
forth in this Article IV. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article IV shall be, to the fullest extent permitted by law, null and void. 

(c) Nothing contained in this Agreement shall be construed to prevent a disposition by any stockholder, member, partner or
other owner of any Partner of any or all of the shares of stock, membership interests, partnership interests or other ownership interests in such Partner and the term “transfer” shall not mean any such disposition. 

Section 4.5 Registration and Transfer of Limited Partner Interests. 

(a) The General Partner shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such
reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the Partnership will provide for the registration and transfer of Limited Partner Interests. 

(b) The Partnership shall not recognize any transfer of Limited Partner Interests evidenced by Certificates until the
Certificates evidencing such Limited Partner Interests are surrendered for registration of transfer. No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate
under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto. Upon surrender of a Certificate for registration of transfer of any
Limited Partner Interests evidenced by a Certificate, and subject to the provisions hereof, the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Certificates evidencing Limited
Partner Interests, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same
aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered.

 (c) By acceptance of the transfer of any Limited Partner Interests in accordance
with this Section 4.5 and except as provided in Section 4.8, each transferee of a Limited Partner Interest (including any nominee holder or an agent or representative acquiring such Limited Partner Interests for the account of another
Person) acknowledges and agrees to the provisions of Section 10.1(a). 
 (d) Subject to (i) the foregoing
provisions of this Section 4.5, (ii) Section 4.3, (iii) Section 4.7, (iv) with respect to any class or series of Limited Partner Interests, the provisions of any statement of designations or an amendment to this Agreement
establishing such class or series, (v) any contractual provisions binding on any Limited Partner and (vi) provisions of applicable law including the Securities Act, Limited Partner Interests shall be freely transferable. 

(e) The General Partner and its Affiliates shall have the right at any time to transfer their Subordinated Units, Common Units
and Incentive Distribution Rights to one or more Persons. 
 Section 4.6 Transfer of the General Partner’s General Partner
Interest. 
 (a) Subject to Section 4.6(b), the General Partner may at its option transfer all or any part of its
General Partner Interest without approval from any other Partner. 
 (b) Notwithstanding anything herein to the contrary, no
transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound
by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability under the Delaware Act of any Limited Partner or cause the Partnership to be treated
as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate
portion thereof, if applicable) of the partnership or membership interest held by the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this
Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.2, be admitted to the Partnership as the General Partner effective immediately prior to the transfer of the General
Partner Interest, and the business of the Partnership shall continue without dissolution. 
 Section 4.7 Restrictions on
Transfers. 
 (a) Notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall
be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities

commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of
its formation, or (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed). 

(b) The General Partner may impose restrictions on the transfer of Partnership Interests if it determines, with the advice of
counsel, that such restrictions are necessary or advisable to (i) avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for U.S. federal income tax purposes or
(ii) preserve the uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may impose such restrictions by amending this Agreement; provided, however, that any amendment that would result
in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such
amendment being effected, by the holders of a majority of the Outstanding Limited Partner Interests of such class. 
 (c)
Nothing contained in this Agreement, other than Section 4.7(a), shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership
Interests are listed or admitted to trading. 
 Section 4.8 Tax Eligibility Certificates; Non-Eligible Holders. 

(a) The General Partner may upon demand or on a regular basis require Limited Partners, and transferees of Limited Partner
Interests in connection with a transfer, to execute a Tax Eligibility Certificate or provide other information as is necessary for the General Partner to determine if any such Limited Partners or transferees are Non-Eligible Holders. 

(b) If any Limited Partner fails to furnish to the General Partner within a reasonable period requested proof of its (and its
owners’) status as an Eligible Holder, or if upon receipt of such Tax Eligibility Certificate or other requested information the General Partner determines that a Limited Partner (or its owner) is a Non-Eligible Holder, the Partnership
Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.9. In addition, the General Partner shall be substituted and treated as the owner of all Partnership Interests owned by a
Non-Eligible Holder. 
 (c) The General Partner shall, in exercising voting rights in respect of Partnership Interests held
by it on behalf of Non-Eligible Holders, cast such votes in the same manner and in the same ratios as the votes of Partners (including the General Partner and its Affiliates) in respect of Partnership Interests other than those of Non-Eligible
Holders are cast. 
 (d) Upon dissolution of the Partnership, a Non-Eligible Holder shall have no right to receive a
distribution in kind pursuant to Section 12.4 but shall be entitled to the cash 

  
 DOMINION

 SECOND AMENDED AND

equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Non-Eligible Holder’s share of any distribution in kind. Such payment and assignment shall be
treated for purposes hereof as a purchase by the Partnership from the Non-Eligible Holder of the portion of his Partnership Interest representing his right to receive his share of such distribution in kind. 

(e) At any time after he can and does certify that he has become an Eligible Holder, a Non-Eligible Holder may, upon
application to the General Partner, request that with respect to any Partnership Interests of such Non-Eligible Holder not redeemed pursuant to Section 4.9, such Non-Eligible Holder be admitted as a Partner, and upon approval of the General
Partner, such Non-Eligible Holder shall be admitted as a Partner and shall no longer constitute a Non-Eligible Holder and the General Partner shall cease to be deemed to be the owner in respect of such Non-Eligible Holder’s Partnership
Interests. 
 (f) If at any time the General Partner determines, with the advice of counsel, that any Group Member is subject
to any federal, state or local law or regulation that would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited
Partner or, if relevant, its owner(s), then the General Partner may adopt such amendments to this Agreement as it determines to be necessary or appropriate to obtain such proof of the nationality, citizenship or other related status of the Limited
Partners and, if relevant, their owners as the General Partner determines to be necessary or appropriate to eliminate or mitigate the risk of cancellation or forfeiture of any properties or interests therein, including provisions similar to those
contained herein for Eligible Taxable Holders. 
 Section 4.9 Redemption of Partnership Interests of Non-Eligible Holders. 

(a) If at any time a Partner fails to furnish a Tax Eligibility Certificate or other information requested within the period of
time specified in amendments adopted pursuant to Section 4.8 or if upon receipt of such Tax Eligibility Certificate, the General Partner determines, with the advice of counsel, that a Partner is a Non-Eligible Holder, the Partnership may,
unless the Partner establishes to the satisfaction of the General Partner that such Partner is an Eligible Holder or has transferred his Limited Partner Interests to a Person who is an Eligible Holder and who furnishes a Tax Eligibility Certificate
to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such Partner as follows: 

(i) The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to
the Partner, at his last address designated on the records of the Partnership or the Transfer Agent, as applicable, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall
specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon redemption of the Redeemable Interests (or, if later in the case of Redeemable Interests evidenced by
Certificates, upon surrender of the Certificate evidencing the Redeemable

Interests) and that on and after the date fixed for redemption no further allocations or distributions to which the Partner would otherwise be entitled in respect of the Redeemable Interests will
accrue or be made. 
 (ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the lesser of
(a) the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Partnership Interests of the class to be so redeemed or (b) the price paid for such Partnership Interests by the Partner, in either
case, multiplied by the number of Partnership Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the
Partnership in the principal amount of the redemption price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date. 

(iii) The Partner or his duly authorized representative shall be entitled to receive the payment for the Redeemable Interests
at the place of payment specified in the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Partner at the place specified in the notice of
redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank). 

(iv) After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner
Interests. 
 (b) The provisions of this Section 4.9 shall also be applicable to Partnership Interests held by a Partner
as nominee of a Person determined to be a Non-Eligible Holder. 
 (c) Nothing in this Section 4.9 shall prevent the
recipient of a notice of redemption from transferring his Partnership Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the
notice of redemption, provided the transferee of such Partnership Interest certifies to the satisfaction of the General Partner that he is an Eligible Holder. If the transferee fails to make such certification, such redemption will be
effected from the transferee on the original redemption date.

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS 

Section 5.1 Organizational Contributions; Contributions by the General Partner and its Affiliates. 

(a) In connection with the formation of the Partnership under the Delaware Act, the General Partner has been admitted as the
General Partner of the Partnership. The 

  
 DOMINION

Organizational Limited Partner made an initial Capital Contribution to the Partnership in the amount of $1,000.00 in the form of a receivable to be settled in cash in exchange for a Limited
Partner Interest equal to a 100% Percentage Interest and has been admitted as a Limited Partner of the Partnership. As of the Closing Date, and effective with the admission of another Limited Partner to the Partnership, the interests of the
Organizational Limited Partner were redeemed as provided in the Contribution Agreement and the initial Capital Contributions of the Organizational Limited Partner were refunded. One-hundred percent of any interest or other profit that may have
resulted from the investment or other use of such initial Capital Contributions was allocated and distributed to the Organizational Limited Partner. 

(b) On the Closing Date and pursuant to the Contribution Agreement, the Organizational Limited Partner contributed to the
Partnership, as a Capital Contribution, the Contributed Interests (as defined in the Contribution Agreement) in exchange for (i) the issuance to the Organizational Limited Partner of 11,847,789 Common Units, 31,972,789 Subordinated Units, and
the right to receive the Deferred Issuance and Distribution and (ii) the issuance to the General Partner of the Incentive Distribution Rights. 

Section 5.2 Contributions by Initial Limited Partners. 

(a) On the Closing Date and pursuant to the Underwriting Agreement, each Underwriter contributed cash to the Partnership in
exchange for the issuance by the Partnership of Common Units to each Underwriter, all as set forth in the Underwriting Agreement. 

(b) Upon the exercise of the Over-Allotment Option, each Underwriter contributed cash to the Partnership in exchange for the
issuance by the Partnership of Common Units to each Underwriter, all as set forth in the Underwriting Agreement. 
 Section 5.3
Interest and Withdrawal. No interest shall be paid by the Partnership on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made
pursuant to this Agreement or upon liquidation of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority
over any other Partner either as to the return of Capital Contributions or as to profits, losses or distributions.  

Section 5.4 Capital Accounts. 

(a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any
case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account
with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions with respect to such
Partnership Interest and (ii) all items of Partnership income and gain computed in accordance with Section 5.4(b) and 

  
 DOMINION

allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash
or property made to the Partner with respect to such Partnership Interest, provided that the Capital Account of a Partner shall not be reduced by the amount of any distributions made with respect to Restricted Common Units held by such
Partner, and (y) all items of Partnership deduction and loss computed in accordance with Section 5.4(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. For the avoidance of doubt, each Series A
Preferred Unit will be treated as a partnership interest in the Partnership that is “convertible equity” within the meaning of Treasury Regulation Section 1.721-2(g)(3), and, therefore, each holder of a Series A Preferred Unit will be
treated as a partner in the Partnership. The initial Capital Account balance in respect of each Series A Preferred Unit shall be the Series A Issue Price, as such amount may be adjusted for any reduction attributable to expenses reimbursable under
the Series A Purchase Agreement. 
 (b) For purposes of computing the amount of any item of income, gain, loss or deduction
that is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification
for U.S. federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided, that: 

(i) Solely for purposes of this Section 5.4, the Partnership shall be treated as owning directly its proportionate share
(as determined by the General Partner based upon the provisions of the applicable Group Member Agreement) of all property owned by (x) any other Group Member that is classified as a partnership for U.S. federal income tax purposes and
(y) any other partnership, limited liability company, unincorporated business or other entity classified as a partnership for U.S. federal income tax purposes of which a Group Member is, directly or indirectly, a partner, member or other equity
holder. 
 (ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership
Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be
allocated among the Partners pursuant to Section 6.1. 
 (iii) The computation of all items of income, gain, loss and
deduction shall be made (x) except as otherwise provided in this Agreement and Treasury Regulation Section 1.704-1(b)(2)(iv)(m), without regard to any election under Section 754 of the Code that may be made by the Partnership, and
(y) as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for U.S. federal income
tax purposes.

 (iv) To the extent an adjustment to the adjusted tax basis of any Partnership
asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital
Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss. 
 (v) In the
event the Carrying Value of Partnership property is adjusted pursuant to Section 5.4(d), any Unrealized Gain resulting from such adjustment shall be treated as an item of gain and any Unrealized Loss resulting from such adjustment shall be
treated as an item of loss. 
 (vi) Any income, gain or loss attributable to the taxable disposition of any Partnership
property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the property’s Carrying Value as of such date. 

(vii) Any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property or Adjusted
Property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d)(2). 
 (viii) To the
extent required by Treasury Regulation Section 1.752-7, the Gross Liability Value of each Liability of the Partnership described in Treasury Regulation Section 1.752-7(b)(3)(i) shall be adjusted at such times as provided in this Agreement
for an adjustment to Carrying Values. The amount of any such adjustment shall be treated for purposes hereof as an item of loss (if the adjustment increases the Carrying Value of such Liability of the Partnership) or an item of gain (if the
adjustment decreases the Carrying Value of such Liability of the Partnership). 
 (c) (i) Except as otherwise provided in
this Section 5.4(c), a transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred. 

(ii) Subject to Section 6.7(b), immediately prior to the transfer of a Subordinated Unit or of a Subordinated Unit that
has converted into a Common Unit pursuant to Section 5.6 by a holder thereof (in each case, other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.4(c)(ii) apply), the Capital Account maintained for
such Person with respect to its Subordinated Units or converted Subordinated Units will (A) first, be allocated to the Subordinated Units or converted Subordinated Units to be transferred in an amount equal to the product of (x) the number
of such Subordinated Units or converted Subordinated Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor,
regardless of whether it has retained any Subordinated Units or converted Subordinated Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Subordinated Units or retained
converted Subordinated Units, if

any, will have a balance equal to the amount allocated under clause (B) above, and the transferee’s Capital Account established with respect to the transferred Subordinated Units or
transferred converted Subordinated Units will have a balance equal to the amount allocated under clause (A) above. 

(iii) Subject to Section 6.8(b), immediately prior to the transfer of an IDR Reset Common Unit by a holder thereof (other
than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.4(c)(iii) apply), the Capital Account maintained for such Person with respect to its IDR Reset Common Units will (A) first, be allocated to the IDR
Reset Common Units to be transferred in an amount equal to the product of (x) the number of such IDR Reset Common Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in
such Capital Account will be retained by the transferor, regardless of whether it has retained any IDR Reset Common Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained IDR
Reset Common Units, if any, will have a balance equal to the amount allocated under clause (B) above, and the transferee’s Capital Account established with respect to the transferred IDR Reset Common Units will have a balance equal to the
amount allocated under clause (A) above. 
 (d) (i) Consistent with Treasury Regulation
Section 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of a Noncompensatory Option, the issuance of Partnership Interests as consideration for
the provision of services (including upon the lapse of a “substantial risk of forfeiture” with respect to a Restricted Common Unit), the issuance of IDR Reset Common Units pursuant to Section 5.10, the conversion of the Combined
Interest to Common Units pursuant to Section 11.3(b), or the conversion of Series A Preferred Units to Common Units pursuant to Section 5.11(b), the Carrying Value of each Partnership property immediately prior to such issuance or after
such conversion shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property; provided, however, that in the event of the issuance of a Partnership Interest pursuant to the
exercise of a Noncompensatory Option (which, for purposes hereof, shall include any conversion of Series A Preferred Units to Common Units pursuant to Section 5.11(b)(vi)) where the right to share in Partnership capital represented by such
Partnership Interest differs from the consideration paid to acquire and exercise such option, the Carrying Value of each Partnership property immediately after the issuance of such Partnership Interest shall be adjusted upward or downward to reflect
any Unrealized Gain or Unrealized Loss attributable to such Partnership property and the Capital Accounts of the Partners shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided further,
however, that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis Partnership Interest or in
the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership.
In determining such Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior

to the issuance of additional Partnership Interests (or, in the case of a Revaluation Event resulting from the exercise of a Noncompensatory Option (which, for purposes hereof, shall include any
conversion of Series A Preferred Units to Common Units pursuant to Section 5.11(b)(vi)), immediately after the issuance of the Partnership Interest acquired pursuant to the exercise of such Noncompensatory Option) shall be determined by the
General Partner using such method of valuation as it may adopt; provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners
at such time and must make such adjustments to such valuation as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). If, after making the allocations of Unrealized Gain and Unrealized Loss as set forth in Section 6.1(d)(xiii),
the Capital Account of each Partner with respect to each Conversion Unit received upon such conversion of the Limited Partner Interest is less than the Per Unit Capital Amount for a then Outstanding Initial Common Unit, then, in accordance with
Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), Capital Account balances shall be reallocated between the Partners holding Common Units (other than Conversion Units) and Partners holding Conversion Units so as to cause the Capital Account
of each Partner holding a Conversion Unit to equal, on a per Unit basis with respect to each such Conversion Unit, the Per Unit Capital Amount for a then Outstanding Initial Common Unit. In making its determination of the fair market values of
individual properties, the General Partner may first determine an aggregate value for the assets of the Partnership that takes into account the current trading price of the Common Units, the fair market value of all other Partnership Interests at
such time and the amount of Partnership Liabilities. The General Partner may allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate). Absent a contrary determination by the
General Partner, the aggregate fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to a Revaluation Event shall be the value that would result in the Capital Account for each Common Unit that is
Outstanding prior to such Revaluation Event being equal to the Event Issue Value. 
 (ii) In accordance with Treasury
Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Carrying Value of
all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all
Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of a distribution other than one made pursuant to Section 12.4, be determined in the same manner as that provided in
Section 5.4(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined by the Liquidator using such method of valuation as it may adopt. 

Section 5.5 Issuances of Additional Partnership Interests and Derivative Instruments. 

(a) Subject to Section 5.7 and Section 5.11(b)(iv), the Partnership may issue additional Partnership Interests and
Derivative Instruments for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners.

Partnership pursuant to Section 5.5(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of
Partnership Interests), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon
dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Partnership Interest (including sinking fund provisions); (v) whether such

Interest into Units pursuant to the terms of this Agreement, (iii) the issuance of Common Units pursuant to Section 5.10, (iv) reflecting admission of such additional Limited Partners in the books and records of the Partnership as the
Record Holders of such Limited Partner Interests and (v) all additional issuances of Partnership Interests. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Interests
being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of
Partnership Interests or in connection with the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental
agency or any National Securities Exchange on which the Units or other Partnership Interests are listed or admitted to trading.

 Section 5.7 Limited Preemptive Right. Except as provided in this
Section 5.7 or as otherwise provided in a separate agreement by the Partnership, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Interest, whether unissued, held in the
treasury or hereafter created. The General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Interests from the Partnership whenever, and on the same terms that,
the Partnership issues Partnership Interests to Persons other than the General Partner and its Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates equal to that which existed immediately
prior to the issuance of such Partnership Interests. The determination by the General Partner to exercise (or refrain from exercising) its right pursuant to the immediately preceding sentence shall be a determination made in its individual capacity.
After the Series A Issuance Date, for as long as any Purchaser or any of its Affiliates owns any Series A Preferred Units, such Purchaser (or its Affiliate designees) shall have the right to purchase any Series A Preferred Units or Series A Parity
Securities proposed to be issued by the Partnership (other than any Series A PIK Units) to any Person other than DRI or any of its Affiliates in the same proportion as the number of Series A Preferred Units then owned by such Purchaser and its
Affiliates has to the aggregate number of Series A Preferred Units then Outstanding, on the same terms and conditions that apply to all offerees in such transaction. In the event of a proposed transaction giving rise to any Purchaser’s
preemptive rights, the Partnership shall provide notice to such Purchaser no later than 20 Business Days prior to the expected consummation of such transaction. Such Purchaser shall provide notice of its election to exercise its preemptive rights
within 10 Business Days after receipt of the notice from the Partnership described in the immediately preceding sentence. 

Section 5.8 Splits and Combinations. 

(a) The Partnership may make a distribution of Partnership Interests to all Record Holders or may effect a subdivision or
combination of Partnership Interests. Upon any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event (subject to the effect of Section 5.8(d) and Section 5.11(b)(vi)(E)), and any amounts
calculated on a per Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units shall be proportionately adjusted retroactive to the beginning of the Partnership. 

(b) Whenever such a distribution, subdivision or combination of Partnership Interests is declared, the General Partner shall
select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of
such notice. 
 (c) Promptly following any such distribution, subdivision or combination, the Partnership may issue
Certificates to the Record Holders of Partnership Interests as of the applicable Record Date representing the new number of Partnership Interests held by such Record Holders, or the General Partner may adopt such other procedures that it determines
to be necessary or appropriate to reflect such changes. If any such combination results in a

smaller total number of Partnership Interests Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of such new Certificate, the surrender of any
Certificate held by such Record Holder immediately prior to such Record Date. 
 (d) The Partnership shall not issue
fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of Section 5.5(d) and this
Section 5.8(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit). 

Section 5.9 Fully Paid and Non-Assessable Nature of Limited Partner Interests. All Limited Partner Interests issued
pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-607 or 17-804 of the
Delaware Act. 
 Section 5.10 Issuance of Common Units in Connection with Reset of Incentive Distribution
Rights. 
 (a) Subject to the provisions of this Section 5.10, the holder of the Incentive
Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the holders of Incentive Distribution Rights) shall have the option, at any time when there are no Subordinated
Units outstanding and the Partnership has made a distribution pursuant to Section 6.4(a)(vii) or Section 6.4(b)(v) for each of the four most recently completed Quarters, to make an election (the “IDR Reset
Election”) to cause the Target Distributions to be reset in accordance with the provisions of Section 5.10(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive
their Pro Rata share of a number of Common Units (the “IDR Reset Common Units”) equal to the result of dividing (i) the amount of cash distributions made by the Partnership for the Quarter immediately preceding the
giving of the Reset Notice in respect of the Incentive Distribution Rights by (ii) the cash distribution made by the Partnership in respect of each Common Unit for the Quarter immediately preceding the giving of the Reset Notice (the
“Reset MQD”) (the number of Common Units determined by such quotient is referred to herein as the “Aggregate Quantity of IDR Reset Common Units”). The making of the IDR Reset Election in the manner
specified in Section 5.10(b) shall cause the Target Distributions to be reset in accordance with the provisions of Section 5.10(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become
entitled to receive Common Units on the basis specified above, without any further approval required by the General Partner or the Unitholders, at the time specified in Section 5.10(c) unless the IDR Reset Election is rescinded pursuant to
Section 5.10(d). 
 (b) To exercise the right specified in Section 5.10(a), the holder of
the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “Reset
Notice”) to the Partnership. Within 10 Business Days after the receipt by  

  
 DOMINION

 SECOND AMENDED AND

the Partnership of such Reset Notice, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership’s determination of the
aggregate number of Common Units that each holder of Incentive Distribution Rights will be entitled to receive. 
 (c) The
holder or holders of the Incentive Distribution Rights will be entitled to receive the Aggregate Quantity of IDR Reset Common Units on the fifteenth Business Day after receipt by the Partnership of the Reset Notice; provided, however,
that the issuance of Common Units to the holder or holders of the Incentive Distribution Rights shall not occur prior to the approval of the listing or admission for trading of such Common Units by the principal National Securities Exchange upon
which the Common Units are then listed or admitted for trading if any such approval is required pursuant to the rules and regulations of such National Securities Exchange. 

(d) If the principal National Securities Exchange upon which the Common Units are then traded has not approved the listing or
admission for trading of the Common Units to be issued pursuant to this Section 5.10 on or before the 30th calendar day following the Partnership’s receipt of the Reset Notice and such approval is required by the rules and regulations of
such National Securities Exchange, then the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall
have the right to either rescind the IDR Reset Election or elect to receive other Partnership Interests having such terms as the General Partner may approve that will provide (i) the same economic value, in the aggregate, as the Aggregate
Quantity of IDR Reset Common Units would have had at the time of the Partnership’s receipt of the Reset Notice, as determined by the General Partner, and (ii) for the subsequent conversion (on terms acceptable to the National Securities
Exchange upon which the Common Units are then traded) of such Partnership Interests into Common Units within not more than 12 months following the Partnership’s receipt of the Reset Notice upon the satisfaction of one or more conditions that
are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights). 

(e) The Target Distributions shall be adjusted at the time of the issuance of Common Units or other Partnership Interests
pursuant to this Section 5.10 such that (i) the Minimum Quarterly Distribution shall be reset to be equal to the Reset MQD, (ii) the First Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target
Distribution shall be reset to equal 125% of the Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD. 

(f) Upon the issuance of IDR Reset Common Units pursuant to Section 5.10(a) (or other Partnership Interests as described
in Section 5.10(d)), the Capital Account maintained with respect to the Incentive Distribution Rights shall (i) first, be allocated to IDR Reset Common Units (or other Partnership Interests) in an amount equal to the product of
(A) the Aggregate Quantity of IDR Reset Common Units (or other Partnership Interests) and (B) the Per Unit Capital Amount for an Initial Common Unit, and (ii) second, any remaining balance

in such Capital Account will be retained by the holder(s) of the Incentive Distribution Rights. If there is not a sufficient Capital Account associated with the Incentive Distribution Rights to
allocate the full Per Unit Capital Amount for an Initial Common Unit to the IDR Reset Common Units in accordance with clause (i) of this Section 5.10(f), the IDR Reset Common Units shall be subject to Section 6.1(d)(x)(B) and
Section 6.1(d)(x)(C). 
 Section 5.11 Establishment of Series A Preferred Units 

(a) General. There is hereby created a class of Units designated as “Series A Convertible Preferred Units” (such Series A
Convertible Preferred 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 5.11 and elsewhere in this Agreement. 
 (b) Rights of Series A Preferred Units. The Series A Preferred
Units shall have the following rights, preferences and privileges and the Series A Preferred Unitholders shall be subject to the following duties and obligations: 

(i) Distributions. 

(A) Subject to Section 5.11(b)(i)(B), commencing with the Quarter ending on December 31, 2016, subject to
Section 5.11(b)(i)(D), the Record Holders of the Series A Preferred Units 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 (1) the Series A Distribution Amount for such Quarter and (2) 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 Distribution is due) ending on or prior to December 31, 2018 (the “Initial Distribution Period”), such Series A Quarterly Distribution shall be paid,
as determined by the General Partner, in Series A PIK Units, in cash, or in a combination of Series A PIK Units and cash. For any Quarter ending after the Initial Distribution Period, all Series A Quarterly Distributions shall be paid
in cash. If, during the Initial Distribution Period, the General Partner elects to pay all or any portion of a Series A Quarterly Distribution in Series A PIK Units, the number of Series A PIK Units to be issued in connection with
such Series A Quarterly Distribution shall equal the quotient of (A) the applicable Series A Distribution Amount (or portion thereof to be paid in Series A PIK Units) divided by (B) the Series A Issue
Price; provided, that instead of issuing any fractional Series A PIK Unit, the Partnership shall round the number of Series A PIK Units issued to each Series A Preferred Unitholder down to the
nearest whole Series A PIK Unit and pay cash in lieu of any resulting fractional unit (with the amount of such cash payment being based on the value of such fractional Series A PIK Unit, which shall be the product of the Closing Price of
the Common Units on the Record Date for such Series A Quarterly Distribution multiplied by the number of Series A Conversion Units into which such fractional Series A PIK Units would be convertible at the applicable Series A
Conversion Rate on such Record Date (without regard to whether any Series A Preferred Units are then convertible)). Each Series A Quarterly Distribution shall be payable quarterly by no later than the earlier of 60 days after the end of the 


  
 DOMINION

 50 








 
applicable Quarter (each such payment date, a “Series A Distribution Payment Date”). If the General Partner establishes an earlier Record Date for any distribution
to be made by the Partnership on other Partnership Interests in respect of any Quarter, then the Record Date established pursuant to this Section 5.11(b)(i) for a Series A Quarterly Distribution in respect of such Quarter shall be the same
Record Date. For the avoidance of doubt, subject to Section 5.11(b)(i)(D), the Series A Preferred Units shall not be entitled to any distributions made pursuant to Section 6.4 for any Quarter so long as the Series A Quarterly Distribution
has been declared and paid in full (including any Series A Unpaid Distributions comprising part thereof) in accordance with this Section 5.11(b)(i) on the Series A Preferred Units with respect to such Quarter.  

(B) If the Partnership fails to pay in full the Series A Distribution Amount of any Series A Quarterly Distribution (in cash or
Series A PIK Units) when due for any Quarter during the Initial Distribution Period, then the Series A Preferred Unitholders entitled to such unpaid Series A Quarterly Distribution shall be deemed to have nonetheless received such Series A Quarterly
Distribution in Series A PIK Units and, accordingly, shall have all other rights under this Agreement as if such Series A PIK Units had, in fact, been issued on the date such distribution was due. If the Partnership fails to pay in full the Series A
Distribution Amount of any Series A Quarterly Distribution in accordance with Section 5.11(b)(i)(A) when due for any Quarter following the Initial Distribution Period, then from and after the first date of such failure and continuing until such
failure is cured by payment in full in cash of all such arrearages, (1) the amount of such unpaid cash distributions (on a per Series A Preferred Unit basis, “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 such payment is due until paid in full and (2) the Partnership shall not be permitted to, and shall not, declare or
make, any 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
the Series A Distribution Amount of any Series A Quarterly Distribution in cash when due); provided, however, that distributions may be declared and paid on the Series A Preferred Units and the Series A Parity
Securities so long as such distributions are declared and paid pro rata so that amounts of distributions declared per Series A Preferred Unit and Series A Parity Security shall in all cases bear to each other the same ratio that accrued and
accumulated distributions per Series A Preferred Unit and Series A Parity Security bear to each other. 
 (C) The aggregate
Series A Distribution Amount (excluding any portion paid in Series A PIK Units) shall be paid out of cash and cash equivalents that is deemed to be Operating Surplus for the applicable Quarter. 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 cash and cash equivalents that is deemed to be Operating Surplus for such Quarter, the amount of cash equal to the cash and cash equivalents that is deemed to be
Operating Surplus for such Quarter will be paid to the Series A Preferred Unitholders Pro Rata and the balance of such Series A Quarterly Distribution shall be unpaid and shall constitute an arrearage and shall accrue and accumulate as set forth in
Section 5.11(b)(i)(B).

 (D) Notwithstanding anything in this Section 5.11(b)(i) to the contrary, with respect to
any Series A Preferred Unit that is converted into a Common Unit, (i) with respect to a distribution to be made to Record Holders as of the Record Date preceding such conversion, the Record Holder as of such Record Date of such Series A
Preferred Unit shall be entitled to receive such distribution in respect of such Series A Preferred Unit on the corresponding Series A Distribution Payment Date, but shall not be entitled to receive such distribution in respect of the Common Units
into which such Series A Preferred Unit was converted on the payment date thereof, and (ii) with respect to a distribution to be made to Record Holders as of any Record Date following such conversion, the Record Holder as of such Record Date of
the Common Units into which such Series A Preferred Unit was converted shall be entitled to receive such distribution in respect of such converted Common Units on the payment date thereof, but shall not be entitled to receive such distribution in
respect of such Series A Preferred Unit on the corresponding Series A Distribution Payment Date. For the avoidance of doubt, if a Series A Preferred Unit is converted into Common Units pursuant to the terms hereof following a Record Date but prior
to the corresponding Series A Distribution Payment Date, then the Record Holder of such Series A Preferred Unit as of such Record Date shall nonetheless remain entitled to receive on the Series A Distribution Payment Date a distribution in respect
of such Series A Preferred Unit pursuant to Section 5.11(b)(i)(A) and, until such distribution is received, Section 5.11(b)(i)(B) shall continue to apply. 

(E) Notwithstanding anything in Article VI to the contrary, the holders of the Incentive Distribution Rights shall not be entitled to receive
distributions or allocations of income or gain that correspond or relate to amounts distributed or allocated to Unitholders in respect of Series A Preferred Units. 

(F) When any Series A PIK Units are payable to a Series A Preferred Unitholder pursuant to this Section 5.11,
the Partnership shall issue the Series A PIK Units to such holder in accordance with Section 5.11(b)(i)(A) (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 have the option to (i) issue to such Series A Preferred Unitholder a certificate or certificates for the number of Series A PIK Units to which such Series A Preferred
Unitholder shall be entitled, or (ii) cause the Transfer Agent to make 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 Section 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. 
 (G) For purposes of maintaining Capital Accounts, if the
Partnership issues one or more Series A PIK Units with respect to a Series A Unit, (i) the Partnership shall be treated as distributing cash with respect to such Series A Preferred Unit in an amount equal to the Series A Issue Price of the
Series A PIK Unit issued in payment of the Series A Quarterly Distribution and (ii) the holder of such Series A Preferred Unit shall be treated as having contributed to the Partnership in exchange for such newly issued Series A PIK Unit an
amount of cash equal to the Series A Issue Price.

 (ii) Issuance of the Series A Preferred Units. The Series A Preferred Units (other than
the Series A PIK Units) shall be issued by the Partnership on the date hereof (A) pursuant to the terms and conditions of the Series A Purchase Agreement and (B) to DRI or its Affiliates up to the number of Series A Preferred Units such
that, when multiplying the number of such Series A Preferred Units by the Series A Preferred Unit Purchase Price (as defined in the Series A Purchase Agreement), the result is equal to $300 million, with any fractional Series A Preferred Units being
rounded to the nearest whole number of Series A Preferred Units. 
 (iii) Voting Rights. 

(A) Except as provided in Section 5.11(b)(iii)(B), the Outstanding Series A Preferred Units shall have voting rights that are identical
to the voting rights of the Common Units and shall vote with the Common Units as a single class, so that each Outstanding Series A Preferred Unit will be entitled to one vote for each Common Unit into which such Series A Preferred Unit would be
convertible at the then applicable Series A Conversion Rate (regardless of whether the Series A Preferred Units are then convertible) on each matter with respect to which each Record Holder of a Common Unit is entitled to vote. Each reference in
this Agreement to a vote of Record Holders of Common Units shall be deemed to be a reference to the Record Holders of Common Units and Series A Preferred Units, voting together as a single class during any period in which any Series A Preferred
Units are Outstanding. 
 (B) Except as provided in Section 5.11(b)(iii)(C), notwithstanding any other provision of this
Agreement, in addition to all other requirements imposed by Delaware law, and all other voting rights granted under this Agreement, the affirmative vote of the Record Holders of the Series A Required Voting Percentage shall be required for any
amendment to this Agreement or the Certificate of Limited Partnership (including by merger or otherwise or any amendment contemplated by and made in accordance with Section 5.11(b)(iv)) that is adverse (other than in a de minimis manner)
to any of the rights, preferences and privileges of the Series A Preferred Units. Without limiting the generality of the preceding sentence, any amendment shall be deemed to have such an adverse impact that is not de minimis if such amendment
would: 
 (1) Reduce the Series A Distribution Amount, change the form of payment of distributions on the Series A Preferred Units,
defer the date from which distributions on the Series A Preferred Units will accrue, cancel any accrued and unpaid distributions on the Series A Preferred Units or any interest accrued thereon (including any Series A Unpaid Distributions, Series A
Partial Period Distributions or Series A PIK Units), or change the seniority rights of the Series A Preferred Unitholders as to the payment of distributions in relation to the holders of any other class or series of Partnership Interests; 

(2) Reduce the amount payable or change the form of payment to the Record Holders of the Series A Preferred Units upon the voluntary or
involuntary liquidation, dissolution or winding up, or sale of all or substantially all of the assets, of the

Partnership, or change the seniority of the liquidation preferences of the Record Holders of the Series A Preferred Units in relation to the rights upon liquidation of the holders of any other
class or series of Partnership Interests; or 
 (3) Make the Series A Preferred Units redeemable or convertible at the option of the
Partnership other than as set forth herein. 
 (C) Notwithstanding anything to the contrary in this Section 5.11(b)(iii), in no event
shall the consent of the Series A Preferred Unitholders, as a separate class, be required in connection with any Series A Change of Control or Partnership Restructuring Event. For the avoidance of doubt, the foregoing shall not limit the voting
rights of any Series A Preferred Unitholder in connection with any vote of Record Holders of Common Units and Series A Preferred Units together as a single class that may be required. 

(D) Notwithstanding any other provision of this Agreement, in addition to all other voting rights granted under this Agreement, the
Partnership shall not declare or pay any distribution from Capital Surplus without the affirmative vote of the Record Holders of the Series A Required Voting Percentage. 

(iv) No Series A Senior Securities; Series A Parity Securities. Other than issuances contemplated by the Series A Purchase
Agreement, the Partnership shall not, without the affirmative vote of the Record Holders of the Series A Required Voting Percentage, issue any (A) Series A Senior Securities (or amend the provisions of any class of Partnership Interests to make
such class of Partnership Interests a class of Series A Senior Securities) or (B) Series A Parity Securities (or amend the provisions of any class of Partnership Interests to make such class of Partnership Interests a class of Series A Parity
Securities) or Series A Preferred Units; provided that, without the consent of the holders of Outstanding Series A Preferred Units (but without prejudice to their rights under Section 5.11(b)(iii)(A)), the Partnership may issue
(1) at any time in the aggregate, up to the greater of (a) an aggregate $[300] million4 of Series A Parity Securities and (b) a number of Series A Parity Securities such that, as of
the date of the issuance of the Series A Parity Securities, the aggregate number of Series A Parity Securities, together with the Series A Preferred Units, in each case on an as-converted basis (or, if the Series A Parity Securities are not
convertible, assuming that such Series A Parity Securities are convertible into a number of Common Units equal to the quotient of (i) the aggregate purchase price for such Series A Parity Securities, divided by (ii) the Average VWAP for
the 30 Trading Day period ending immediately prior to such issuance (such Common Units, the “Series A Parity Equivalent Units”)), equals no more than 15% of all Outstanding Common Units and Subordinated Units
(including as Outstanding for such purposes, (i) any Common Units issuable in respect of the Series A Preferred Units at the then-applicable Series A Conversion Rate (regardless of whether the Series A Preferred Units are then convertible),
(ii) any Common Units issuable in respect of Series A Parity Securities (including any warrants issued in connection with Series A Parity Securities) at the initial or then-applicable conversion rate, as applicable, (iii) any Common Units

Partnership, (iv) any Series A Parity Equivalent Units and (v) any Common Units that would otherwise be excluded by operation of the definition of the term “Outstanding”), and
(2) if a number of Series A Preferred Units having an aggregate Series A Issue Price of less than $100 million is then Outstanding, such number of Series A Parity Securities as determined by the General Partner. Subject to Section 5.11(b)(vi)(E),
the Partnership may, without any vote of the holders of Outstanding Series A Preferred Units (but without prejudice to their rights under Section 5.11(b)(iii)(A)), issue the Series A PIK Units contemplated by this Agreement or create (by
reclassification or otherwise) and issue Series A Junior Securities in an unlimited amount.

evidencing a Series A Preferred Unit shall bear a restrictive notation in substantially the form set forth in Exhibit A. 
 (vi)
Conversion. 
 (A) At the Option of the Series A Preferred Unitholders. Beginning with the earlier of (1) [●]5, and (2) immediately prior to the liquidation of the Partnership under Section 12.4, the Series A Preferred Units owned by any Series A Preferred Unitholder shall be convertible, in whole or in
part, at any time and from time to time upon the request of such Series A Preferred Unitholder, but not more than once per Quarter by such Series A Preferred Unitholder (inclusive of any conversion by such Series A Preferred Unitholder’s
Affiliates, with each Series A Preferred Unitholder and its Affiliates being entitled to a single conversion right per Quarter), into a number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by (y) in
the case of clause (1), the Series A Conversion Rate at such time and (z) in the case of clause (2), the Series A COC Conversion Rate; provided, however, that the Partnership shall not be obligated to honor any such conversion request
if such conversion request does not involve an underlying value of Common Units of at least $50 million (taking into account and including any concurrent conversion requests by any Affiliates of such Series A Preferred Unitholder) based on the
Closing Price of Common Units on the Trading Day immediately preceding the Series A Conversion Notice Date (or a lesser amount to the extent such exercise covers all of such Series A Preferred Unitholder’s Series A Preferred Units). Immediately
upon the issuance of Common Units as a result of any conversion of Series A Preferred Units, subject to Section 5.11(b)(i)(D), all rights of the Series A Converting Unitholder with respect to such Series A Preferred Units shall cease, including any
further accrual of distributions, and such Series A Converting Unitholder thereafter shall be treated for all purposes as the owner of Common Units. Fractional Common Units shall not be issued to any Person pursuant to this Section 5.11(b)(vi)(A)
(each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Conversion Notice Date). 

(B) At the Option of the Partnership. At any time following [●]6, the
Partnership shall have the option at any time, but not more than once per Quarter, to convert all or any portion of the Series A Preferred Units then Outstanding into a number of

Person pursuant to this Section 5.11(b)(vi)(B) (each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A
Forced Conversion Notice Date). Notwithstanding the foregoing, in order for the Partnership to exercise such option: 
 (1) The Closing
Price of the Common Units must be greater than one hundred forty percent (140%) of the Series A Issue Price for the 20 Trading Day period immediately preceding the Series A Forced Conversion Notice Date; 

(2) The average daily trading volume of the Common Units on the National Securities Exchange on which the Common Units are then listed or
admitted to trading must be equal to or exceed 100,000 (as such amount may be adjusted to reflect any Unit split, combination or similar event) for the 20 Trading Day period immediately preceding the Series A Forced Conversion Notice Date; 

(3) The Common Units are listed or admitted to trading on a National Securities Exchange; and 

(4) The Partnership must have an effective registration statement on file with the Commission covering resales of the underlying Common Units
to be received upon any such conversion; 
 provided, that each such conversion by the Partnership shall be for an aggregate amount of Series A
Preferred Units involving an underlying value of Common Units of at least $100 million based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Forced Conversion Notice Date (or a lesser amount if such amount
includes all then Outstanding Series A Preferred Units) and shall be allocated among the Series A Preferred Unitholders (or the Series A Preferred Unitholders excluding DRI and its Affiliates, as elected by the Partnership) on a Pro Rata basis or on
such other basis as may be agreed upon by all Series A Preferred Unitholders. 
 (C) Conversion Notice. 

(1) To convert Series A Preferred Units into Common Units pursuant to Section 5.11(b)(vi)(A), a Series A Converting Unitholder shall give
written notice (a “Series A Conversion Notice,” and the date such notice is received, a “Series A Conversion Notice Date”) to the Partnership stating that such Series A Preferred Unitholder elects to
so convert Series A Preferred Units pursuant to Section 5.11(b)(vi)(A), the number of Series A Preferred Units to be converted and the Person to whom such Common Units should be issued. 

(2) To convert Series A Preferred Units into Common Units pursuant to Section 5.11(b)(vi)(B), the Partnership shall give written notice
(a “Series A Forced Conversion Notice,” and the date such notice is received, a “Series A Forced

Conversion Notice Date”) to each Record Holder of Series A Preferred Units stating that the Partnership elects to force conversion of Series A Preferred Units pursuant to
Section 5.11(b)(vi)(B) and the number of Series A Preferred Units to be so converted. The Series A Conversion Units shall be issued in the name of the Record Holder of such Series A Preferred Units. 

(D) Timing. If a Series A Conversion Notice is delivered by a Series A Preferred Unitholder to the Partnership or a Series A Forced
Conversion Notice is delivered by the Partnership to a Series A Preferred Unitholder, each in accordance with Section 5.11(b)(vi)(C), the Partnership shall issue the applicable Series A Conversion Units no later than five Business Days after
the Series A Conversion Notice Date or the Series A Forced Conversion Notice Date, as the case may be, occurs (any date of issuance of such Common Units, and any date of issuance of Common Units upon conversion of Series A Preferred Units pursuant
to this Section 5.11(b)(vi) or Section 5.11(b)(vii), a “Series A Conversion Date”). On the Series A Conversion Date, the Partnership shall instruct, and shall use its commercially reasonable efforts to cause, its
Transfer Agent to electronically transmit the Series A Conversion Units issuable upon conversion to such Series A Preferred Unitholder (or designated recipient(s)), by crediting the account of the Series A Preferred Unitholder (or designated
recipient(s)) through its Deposit Withdrawal Agent Commission system. The parties agree to coordinate with the Transfer Agent to accomplish this objective. Upon issuance of Series A Conversion Units to the Series A Converting Unitholder, all rights
under the converted Series A Preferred Units shall cease, and such Series A Converting Unitholder shall be treated for all purposes as the Record Holder of such Series A Conversion Units. 

(E) Distributions, Combinations, Subdivisions and Reclassifications by the Partnership. If, after the Series A Issuance Date, the
Partnership (i) makes a distribution on its Common Units payable in Common Units or other Partnership Interests, (ii) subdivides or splits its outstanding Common Units into a greater number of Common Units, (iii) combines or
reclassifies its Common Units into a lesser number of Common Units, (iv) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a merger, consolidation or business combination
in which the Partnership is the surviving Person), (v) effects a Pro Rata repurchase of Common Units, in each case other than in connection with a Series A Change of Control (which shall be governed by Section 5.11(b)(vii)),
(vi) issues to holders of Common Units, in their capacity as holders of Common Units, rights, options or warrants entitling them to subscribe for or purchase Common Units at less than the market value thereof, (vii) distributes to holders
of Common Units evidences of indebtedness, Partnership Interests (other than Common Units) or other assets (including securities, but excluding any distribution referred to in clause (i), any rights or warrants referred to in clause (ii), any
consideration payable in connection with a tender or exchange offer made by the Partnership or any of its subsidiaries and any distribution of Units or any class or series, or similar Partnership Interest, of or relating to a subsidiary or other
business unit in the case of certain spin-off transactions described below), or (viii) consummates a spin-off, where the Partnership makes a distribution to all holders of Common Units consisting of Units of any class or series, or similar
equity interests of, or relating to, a subsidiary or other business unit, then the Series A Conversion Rate and, solely for purposes of Section

5.11(b)(vi)(B)(1), the Series A Issue Price, in each case, in effect at the time of the Record Date for such distribution or the effective date of any such other transaction shall be
proportionately adjusted: (1) in respect of clauses (i) through (iv) above, so that the conversion of the Series A Preferred Units after such time shall entitle each Series A Preferred Unitholder to receive the aggregate number of
Common Units (or any Partnership Interests into which such Common Units would have been combined, consolidated, merged or reclassified, as applicable) that such Series A Preferred Unitholder would have been entitled to receive if the Series A
Preferred Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, (2) in respect of clauses (v) through (viii) above, in the reasonable discretion of the General Partner
to appropriately ensure that the Series A Preferred Units are convertible into an economically equivalent number of Common Units after taking into account the event described in clauses (vi) through (viii) above, and (3) in addition
to the foregoing, in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the Partnership shall provide effective provisions to ensure that the provisions in this Section 5.11 relating to
the Series A Preferred Units shall not be abridged or amended and that the Series A Preferred Units shall thereafter retain the same powers, economic rights, preferences and relative participating, optional and other special rights, and the
qualifications, limitations and restrictions thereon, that the Series A Preferred Units had immediately prior to such transaction or event, and, solely for purposes of Section 5.11(b)(vi)(B)(1), the Series A Issue Price, and any other terms of
the Series A Preferred Units that the General Partner in its reasonable discretion determines require adjustment to achieve the economic equivalence described below, shall be proportionately adjusted to take into account any such subdivision, split,
combination or reclassification. An adjustment made pursuant to this Section 5.11(b)(vi)(E) shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date
in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person) or split. Such adjustment shall be made
successively whenever any event described above shall occur. 
 (F) No Adjustments for Certain Items. Notwithstanding any of the
other provisions of this Section 5.11(b)(vi), no adjustment shall be made to the Series A Conversion Rate or the Series A Issue Price pursuant to Section 5.11(b)(vi)(E) as a result of any of the following: 

(1) Any issuance of Partnership Interests in exchange for cash; 

(2) Any grant of Common Units or options, warrants or rights to purchase or receive Common Units or the issuance of Common Units upon the
exercise or vesting of any such options, warrants or rights in respect of services provided to or for the benefit of the Partnership or its Subsidiaries, under compensation plans and agreements approved by the General Partner (including any
long-term incentive plan); 
 (3) Any issuance of Common Units as all or part of the consideration to effect (i) the closing of any
acquisition by the Partnership of assets or equity

interests of a third party in an arm’s-length transaction, (ii) closing of any acquisition by the Partnership of assets or equity interests of DRI or any of its Affiliates or
(iii) the consummation of a merger, consolidation or other business combination of the Partnership with another entity in which the Partnership survives and the Common Units remain Outstanding to the extent any such transaction set forth in
clause (i), (ii) or (iii) above is validly approved by the General Partner; or 
 (4) The issuance of Common
Units upon conversion of the Series A Preferred Units or Series A Parity Securities. 
 Notwithstanding anything in this Agreement to the contrary, whenever
the issuance of a Partnership Interest or other event would require an adjustment to the Series A Conversion Rate under one or more provisions of this Agreement, only one adjustment shall be made to the Series A Conversion Rate in respect of such
issuance or event. 
 Notwithstanding anything to the contrary in Section 5.11(b)(vi)(E), unless otherwise determined by the General Partner, no
adjustment to the Series A Conversion Rate or the Series A Issue Price shall be made with respect to any distribution or other transaction described in Section 5.11(b)(v)(E) if the Series A Preferred Unitholders are entitled to participate in
such distribution or transaction as if they held a number of Common Units issuable upon conversion of the Series A Preferred Units immediately prior to such event at the then applicable Series A Conversion Rate, without having to convert their
Series A Preferred Units. 
 (vii) Series A Change of Control. 

(A) Subject to Section 5.11(b)(vi)(B), in the event of a Series A Cash COC Event, the Outstanding Series A Preferred Units shall be
automatically converted, without requirement of any action of the Series A Preferred Unitholders, into Common Units immediately prior to the closing of the applicable Series A Change of Control at the Series A COC Conversion Rate. 

(B) Subject to Section 5.11(b)(vi)(B), at least 10 Business Days prior to consummating a Series A Change of Control (other than a Series
A Cash COC Event), the Partnership shall provide written notice thereof to the Series A Preferred Unitholders. Subject to Section 5.11(b)(vi)(B), if a Series A Change of Control (other than a Series A Cash COC Event) occurs, then each Series A
Preferred Unitholder, with respect to all but not less than all of its Series A Preferred Units, by notice given to the Partnership within 10 Business Days of the date the Partnership provides written notice of the execution of definitive agreements
that provide for such Series A Change of Control, shall be entitled to elect one of the following (with the understanding that any Series A Preferred Unitholder who fails to timely provide notice of its election to the Partnership shall be deemed to
have elected the option set forth in sub-clause (1) below): 
 (1) Convert all, but not less than all, of such Series A Preferred
Unitholder’s Outstanding Series A Preferred Units into Common Units, at the then-applicable Series A Conversion Rate;

 (2) Except as described below or in the case of a Series A Change of Control involving a
transaction described in clause (d) of the definition of Series A Change of Control, if the Partnership will not be the surviving entity of such Series A Change of Control or the Partnership will be the surviving entity but its Common Units
will cease to be listed or admitted to trading on a National Securities Exchange, require the Partnership to use its commercially reasonable efforts to deliver or to cause to be delivered to the Series A Preferred Unitholders, in exchange for their
Series A Preferred Units upon such Series A Change of Control, a security in the surviving entity or the parent of the surviving entity that has substantially similar rights, preferences and privileges as the Series A Preferred Units, including, for
the avoidance of doubt, the right to distributions equal in amount and timing to those provided in Section 5.11(b)(i) and a conversion rate proportionately adjusted such that the conversion of such security in the surviving entity or parent of
the surviving entity immediately following the Series A Change of Control would entitle the Record Holder to the number of common securities of such entity (together with a number of common securities of equivalent value to any other assets received
by holders of Common Units in such Series A Change of Control) which, if a Series A Preferred Unit had been converted into Common Units immediately prior to such Series A Change of Control, such Record Holder would have been entitled to receive
immediately following such Series A Change of Control (such security in the surviving entity, a “Series A Substantially Equivalent Unit”); provided, however, that, if (x) the Partnership is unable to deliver or
cause to be delivered Series A Substantially Equivalent Units to any Series A Preferred Unitholder in connection with such Series A Change of Control or (y) such Series A Change of Control involves a transaction described in clause (d) of
the definition of Series A Change of Control, each Series A Preferred Unitholder shall be entitled to (I) require conversion or redemption of such Series A Preferred Units in the manner contemplated by subclause (1) or (4) of this
Section 5.11(b)(vii)(B) (at such holder’s election) or (II) convert the Series A Preferred Units held by such Series A Preferred Unitholder immediately prior to such Series A Change of Control into a number of Common Units at a conversion
ratio equal to the quotient of: (a) the product of (i) 160% multiplied by (ii) the Series A Issue Price less the Series A Preferred Unitholder’s Pro Rata portion of the sum of (A) all cash distributions paid on all Series A
Preferred Units on or prior to the date of the Series A Change of Control and (B) an amount in cash equal to the aggregate of the Series A Quarterly Distributions paid in Series A PIK Units (based on the value of such Series A
PIK Units on the applicable Series A PIK Payment Date) on or before the date of the Series A Change of Control, divided by (b) an amount equal to 95% of the Average VWAP for the 30 Trading Day period prior to the closing of the Series
A Change of Control; provided, however, that such ratio shall in no event exceed a value per Series A Preferred Unit equal to (aa) 120% of the Series A Issue Price in the case of a Series A Change of Control occurring prior to [●]7, (bb) 130% of the Series A Issue Price in the case of a Series A Change of Control occurring on or after [●]8, but prior to [●]9,and (cc) 140% of the Series A Issue Price in the case of a Series A Change of Control occurring on or after [●]10 but prior to [●]11.

 (3) If the Partnership is the surviving entity of such Series A Change of Control, continue to
hold Series A Preferred Units; or 
 (4) Require the Partnership to redeem the Series A Preferred Units at a price per Series A Preferred
Unit equal to the sum of (A) the product of 101% and the sum of (x) the Series A Issue Price plus (y) Series A Unpaid Distributions on the applicable Series A Preferred Unit, plus (B) Series A Partial Period Distributions on the
applicable Series A Preferred Unit. Any redemption pursuant to this sub-clause (4) shall, as determined by the General Partner, be paid in cash and/or Common Units. If all or any portion of such redemption is to be paid in Common Units,
the Common Units to be issued shall be valued at 95% of the Average VWAP for the 30 Trading Day period ending on the fifth Trading Day immediately prior to the Series A Change of Control. No later than three Trading Days prior to the consummation of
the related Series A Change of Control, the Partnership shall deliver a written notice to the Record Holders of the Series A Preferred Units stating the date on which the Series A Preferred Units will be redeemed and the Partnership’s
computation of the amount of cash or Common Units to be received by the Record Holder upon redemption of such Series A Preferred Units. If the Partnership shall be the surviving entity of the related Series A Change of Control, then no later than 10
Business Days following the consummation of such Series A Change of Control, the Partnership shall remit the applicable cash or Common Unit consideration to the Record Holders of then Outstanding Series A Preferred Units. If the Partnership shall
not be the surviving entity of the related Series A Change of Control, then the Partnership shall remit the applicable cash or Common Unit immediately prior to the consummation of the Series A Change of Control. The Record Holders shall deliver to
the Partnership any Certificates representing the Series A Preferred Units as soon as practicable following the redemption. Record Holders of the Series A Preferred Units shall retain all of the rights and privileges thereof unless and until the
consideration due to them as a result of such redemption shall be paid in full in cash or Common Units, as applicable. After any such redemption, any such redeemed Series A Preferred Unit shall no longer constitute an issued and Outstanding Limited
Partner Interest. 
 (viii) Series A Preferred Unit Transfer Restrictions. 

(A) Notwithstanding any other provision of this Section 5.11(b)(viii) (other than the restriction on transfers to a Person that is not a
U.S. resident individual or an entity that is not treated as a U.S. corporation or partnership set forth in Section 5.11(b)(viii)(B)), subject to Section 4.7, each Series A Preferred Unitholder shall be permitted to transfer any Series A
Preferred Units owned by such Series A Preferred Unitholder to any of its Affiliates or to any other Series A Preferred Unitholder.

 (B) Without the prior written consent of the Partnership, except as specifically provided in the
Purchase Agreement or this Agreement, each Series A Purchaser shall not, (a) during the period commencing on the Series A Issuance Date and ending on [●]12, 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,
(b) during the period commencing on the Series A Issuance Date and ending on [●]13, directly or indirectly engage in any short sales or other derivative or hedging transactions with
respect to the Series A Preferred Units or Common Units that are designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred
Units, (c) transfer any Series A Preferred Units to any non-U.S. resident individual, non-U.S. corporation or partnership, or any other non-U.S. entity, including any foreign governmental entity, including by means of any swap or other
transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred Units,
regardless of whether any transaction described above is to be settled by delivery of Series A Preferred Units, Common Units or other securities, in cash or otherwise, (provided, however, that the foregoing shall not apply if, prior to any such
transfer or arrangement, such individual, corporation, partnership or other entity establishes to the satisfaction of the Partnership, its entitlement to a complete exemption from tax withholding, including under Code Sections 1441, 1442, 1445 and
1471 through 1474, and the Treasury regulations thereunder), or (d) effect any transfer of Series A Preferred Units or Series A Conversion Units in a manner that violates the terms of this Agreement; provided, however, that such
Series A Preferred Unitholder may pledge all or any portion of its Series A Preferred Units to any holders of obligations owed by the Series A Preferred Unitholders, including to the trustee for, or representative of, such Series A Preferred
Unitholders, and a foreclosure by any such pledgee on any such pledged Series A Preferred Units shall not be considered a violation or breach of this Section 5.11(b)(viii)(B); provided, further, that such Series A Preferred Unitholder may
transfer any Series A Preferred Units to (i) an Affiliate of such Series A Preferred Unitholder or (ii) any Series A Purchaser. Notwithstanding the foregoing, any transferee receiving any Series A Preferred Units pursuant to this
Section 5.11(b)(viii)(B) shall agree to the restrictions set forth in this Section 5.11(b)(viii)(B). For the avoidance of doubt, in no way does this Section 5.11(b)(viii)(B) prohibit changes in the composition of any Series A
Preferred Unitholder or its partners or members so long as such changes in composition only relate to changes in direct or indirect ownership of such Series A Preferred Unitholder among such Series A Preferred Unitholder, its Affiliates and the

provided, however, that this Section 5.11(b)(viii)(C) shall not eliminate, modify or reduce the obligations set forth in subclauses (b), (c) or (d) of Section 5.11(b)(viii)(B).

Partner (or its successor) transfers property (including cash) to or on behalf of any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement
from) the Partnership for the value of such property, then for tax purposes, (x) such property shall be treated as having been contributed to the Partnership by such Partner and (y) immediately thereafter the Partnership shall be treated
as having transferred such property to or on behalf of the employee or other service provider.

forth in the definition of “Outstanding,” Restricted Common Units shall not be considered to be Outstanding Common Units for purposes of this Section 6.1 and references herein to Unitholders holding Common Units shall be to such

occurring during a taxable period shall be allocated in the manner set forth in this Section 6.1(c). All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations
provided under this Section 6.1 and after all distributions of cash and cash equivalents provided under Section 6.4 and Section 6.5 have been made; provided, however, that solely for purposes of this Section 6.1(c),
Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4; and provided, further, that Net Termination Gain or Net Termination Loss attributable to (i) Liquidation Gain or Liquidation Loss shall
be allocated on the last day of the taxable period during which such Liquidation Gain or Liquidation Loss occurred, (ii) Sale Gain or Sale Loss shall be allocated as of the time of the sale or disposition giving rise to such Sale Gain or Sale

amount of any Net Termination Gain arising in connection with a Revaluation Event that is allocated to the holders of Incentive Distribution Rights in a manner that will result (1) in the Capital Account for each Common Unit that is Outstanding
prior to such Revaluation Event being equal to the Event Issue Value and (2) to the greatest extent possible, the Capital Account with respect to the Incentive Distribution Rights that are Outstanding prior to such Revaluation Event being equal
to the amount of Net Termination Gain that would be allocated to the holders of the Incentive Distribution Rights pursuant to this Section 6.1(c)(i) if (i) the Capital Accounts with respect to all Partnership Interests that were
Outstanding immediately prior to such Revaluation Event were equal to zero and (ii) the aggregate Carrying Value of all Partnership property equaled the aggregate amount of all Partnership Liabilities.

 (ii) Except as otherwise provided by Section 6.1(c)(iii) or
Section 6.1(c)(iv), Net Termination Loss (including a pro rata part of each item of income, gain, loss and deduction taken into account in computing Net Termination Loss) shall be allocated: 

(A) First, if Subordinated Units remain Outstanding, to all Unitholders holding Subordinated Units, to the extent of and in
proportion to the positive balances in their Adjusted Capital Accounts in respect of such Subordinated Units until the Adjusted Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero; 

(B) Second, to all Unitholders holding Common Units, to the extent of and in proportion to the positive balances in their
Adjusted Capital Accounts in respect of such Common Units, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; and 

(C) Third, to all Series A Preferred Unitholders, to the extent of and in proportion to the positive balances in their
Adjusted Capital Accounts in respect of their Series A Preferred Units, until the Adjusted Capital Account in respect of each Series A Preferred Unit then Outstanding has been reduced to zero; and 

(D) Fourth, the balance, if any, 100% to the General Partner. 

(iii) Net Termination Loss attributable to Revaluation Loss and deemed recognized prior to the conversion of the last
Outstanding Subordinated Unit and prior to the Liquidation Date shall be allocated: 
 (A) First, to the Unitholders (other
than the Series A Preferred Unitholders), Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding equals the Event Issue Value; provided, however, that Net Termination Loss shall not be allocated pursuant to this
Section 6.1(c)(iii)(A) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit in its Adjusted Capital Account); 

(B) Second, to all Unitholders holding Subordinated Units, to the extent of and in proportion to the positive balances in
their Adjusted Capital Accounts in respect of such Subordinated Units, until the Adjusted Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero;

 (C) Third, to all Unitholders holding Common Units, to the extent of and in
proportion to the positive balances in their Adjusted Capital Accounts in respect of such Common Units, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; 

(D) Fourth, to all Series A Preferred Unitholders, to the extent of and in proportion to the positive balances in their
Adjusted Capital Accounts in respect of their Series A Preferred Units, until the Adjusted Capital Account in respect of each Series A Preferred Unit then Outstanding has been reduced to zero; and 

(E) Fifth, the balance, if any, to the General Partner. 

(iv) If (A) a Net Termination Loss has been allocated pursuant to Section 6.1(c)(iii), (B) a Net Termination
Gain or Net Termination Loss subsequently occurs (other than as a result of a Revaluation Event) prior to the conversion of the last Outstanding Subordinated Unit and (C) after tentatively making all allocations of such Net Termination Gain or
Net Termination Loss provided for in Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable, the Capital Account in respect of each Common Unit does not equal the amount such Capital Account would have been if Section 6.1(c)(iii) had
not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable, then items of income, gain, loss and deduction
included in such Net Termination Gain or Net Termination Loss and otherwise allocable to the holders of Common Units, Subordinated Units, Incentive Distribution Rights or the General Partner (but not any items otherwise allocable to the Series A
Preferred Unitholders with respect to their Series A Preferred Units), as applicable, shall be specially allocated among the General Partner and all Unitholders (other than the Series A Preferred Unitholders with respect to their Series A Preferred
Units) in a manner that will, to the maximum extent possible, cause the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all allocations of Net Termination Gain and Net Termination Loss had
been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable. 
 (d) Special Allocations.
Notwithstanding any other provision of this Section 6.1, the following special allocations shall be made for each taxable period in the following order: 

(i) Partnership Minimum Gain Chargeback. Notwithstanding any other provision of this Section 6.1, if there is a net
decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury
Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and the


  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 68 








 
allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d) with respect to such taxable period
(other than an allocation pursuant to Section 6.1(d)(vi) or Section 6.1(d)(vii)). This Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and
shall be interpreted consistently therewith. 
 (ii) Chargeback of Partner Nonrecourse Debt Minimum Gain.
Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any
Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in
the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and
the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d), other than Section 6.1(d)(i) and other than an allocation pursuant to
Section 6.1(d)(vi) or Section 6.1(d)(vii), with respect to such taxable period. This Section 6.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation
Section 1.704-2(i)(4) and shall be interpreted consistently therewith. 
 (iii) Priority Allocations. 

(A) If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to
Section 12.4 or with respect to Series A Preferred Units) with respect to a Unit for a taxable period exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit for the same taxable period (the
amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess Distribution Unit”), then there shall be allocated gross income and gain
to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii)(A) for the
current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution. 
 (B) After the
application of Section 6.1(d)(iii)(A), the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated to the holders of Incentive Distribution Rights, Pro Rata, until the aggregate amount of such
items allocated to the holders of Incentive Distribution Rights pursuant to this 

  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 69 








 
Section 6.1(d)(iii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions made to the holders of Incentive
Distribution Rights from the Closing Date to a date 45 days after the end of the current taxable period. 
 (iv) Qualified
Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of
Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit
balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(iv) shall be made only if and to the extent
that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iv) were not in this Agreement. 

(v) Gross Income Allocation. In the event any Partner has a deficit balance in its Capital Account at the end of any
taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections
1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(v) shall
be made only if and to the extent that such Partner would have a deficit balance in its Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if Section 6.1(d)(iv) and this
Section 6.1(d)(v) were not in this Agreement. 
 (vi) Nonrecourse Deductions. Nonrecourse Deductions for any
taxable period shall be allocated to the Partners Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury
Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements. 

(vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to
the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner
bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, the Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic
Risk of Loss.

 (viii) Nonrecourse Liabilities. For purposes of Treasury Regulation
Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated
first, to any Partner that contributed property to the Partnership in proportion to and to the extent of the amount by which each such Partner’s share of any Section 704(c) built-in gains exceeds such Partner’s share of Nonrecourse
Built-in Gain, and second, among the Partners Pro Rata. 
 (ix) Code Section 754 Adjustments. To the extent an
adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation
Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as a result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Partnership, the amount of such adjustment to the
Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) taken into account pursuant to Section 5.4, and such item of gain or loss shall be
specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations. 

(x) Economic Uniformity; Changes in Law. 

(A) At the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the
Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii) (and without prejudice to the allocations required
to be made pursuant to Section 6.1(c)(i)(B)), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the
proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital
Account maintained with respect to such Final Subordinated Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of
(1) the number of Final Subordinated Units held by such Partner and (2) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated
Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing
such economic uniformity will be available to the General Partner only if the method for

allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.4(c)(ii) does not otherwise
provide such economic uniformity to the Final Subordinated Units. 
 (B) Prior to making any allocations pursuant to
Section 6.1(d)(xiv)(C), if a Revaluation Event occurs during any taxable period of the Partnership ending upon, or after, the issuance of IDR Reset Common Units pursuant to Section 5.10, after the application of Section 6.1(d)(x)(A),
any Unrealized Gains and Unrealized Losses shall be allocated among the Partners in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to (i) each Series A Preferred Unit equaling the Series A
Issue Price and (ii) such IDR Reset Common Units issued pursuant to Section 5.10 equaling the product of (1) the Aggregate Quantity of IDR Reset Common Units and (2) the Per Unit Capital Amount for an Initial Common Unit. 

(C) Prior to making any allocations pursuant to Section 6.1(d)(xiv)(C), if a Revaluation Event occurs, and after the
application of Section 6.1(d)(x)(A) and Section 6.1(d)(x)(B), Unrealized Gain shall be allocated to the Series A Preferred Unitholders in a manner that to the nearest extent possible results in the Capital Accounts maintained with resepct
to each Series A Preferred Unit equaling the Series A Issue Price and then any remaining Unrealized Gains and Unrealized Losses shall be allocated to the holders of (A) Outstanding Privately Placed Units, Pro Rata, or (B) Outstanding
Common Units (other than Privately Placed Units), Pro Rata, as applicable, in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to each Privately Placed Unit equaling the Per Unit Capital Amount for
an Initial Common Unit. In addition, if (i) the holders of Outstanding Privately Placed Units publicly trade any such Units during a taxable period and (ii) the Capital Accounts maintained with respect to each such Privately Placed Unit
did not equal the Per Unit Capital Amount for an Initial Common Unit, then items of gross income, gain, deduction and loss for such taxable period shall be allocated to the holders of (A) such Outstanding Privately Placed Units, Pro Rata, or
(B) Outstanding Common Units (other than such Outstanding Privately Placed Units), Pro Rata, as applicable, in amounts necessary to achieve such Capital Account equivalency. 

(D) With respect to any taxable period during which an IDR Reset Common Unit is transferred to any Person who is not an
Affiliate of the transferor, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to the transferor Partner of such transferred IDR Reset Common Unit until such


  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 72 








 
transferor Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such transferred IDR Reset Common Unit to an amount equal to
the Per Unit Capital Amount for an Initial Common Unit. 
 (E) For the proper administration of the Partnership and for the
preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (1) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost
recovery deductions; (2) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (3) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of
Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof) that are publicly traded as a single class.
The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.1(d)(x)(E) only if such conventions, allocations or amendments would not have a material adverse
effect on the Partners, the holders of any class or classes of Outstanding Limited Partner Interests or the Partnership. 

(xi) Allocations with Respect to Series A Preferred Units. Notwithstanding any other provision of this Section 6.1
(other than the Required Allocations): 
 (A) Items of Partnership gross income shall be allocated to the Series A Preferred
Unitholders, Pro Rata, until the aggregate amount of gross income allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all cash
distributions made with respect to such Series A Preferred Unit pursuant to Section 5.11(b)(i) from the date such Series A Preferred Unit was issued to a date 60 days after the end of the current taxable year. 

(B) Items of Partnership gross income shall be allocated to the Series A Preferred Unitholders, Pro Rata, until the aggregate
amount of gross income allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Net Losses allocated to such Series A Preferred
Unitholder pursuant to Section 6.1(b)(iii) for all previous taxable years. 
 (C) If (A) prior to the conversion
of the last Outstanding Series A Preferred Unit (i) the Liquidation Date occurs or (ii) Sale Gain or Sale Loss is recognized, and (B) after having made all other allocations 

  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 73 








 
provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs or Sale Gain or Sale Loss is recognized, the Per Unit Capital Amount of each Series A Preferred
Unit does not equal or exceed the Series A Liquidation Value, then items of gross income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to
cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation).
For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of gross income and gain that would
otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs or Sale Gain or Sale Loss is recognized, reallocated from the Unitholders holding Units other than Series A Preferred
Units to Unitholders holding Series A Preferred Units. If (i) the Liquidation Date occurs or Sale Gain or Sale Loss is recognized on or before the date (not including any extension of time) prescribed by law for the filing of the
Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs or Sale Gain or Sale Loss is recognized and (ii) the reallocation of items for the taxable period
in which the Liquidation Date occurs or Sale Gain or Sale Loss is recognized as set forth above in this Section 6.1(d)(xi)(C) fails to achieve the Per Unit Capital Amounts described above, then items of gross income, gain, loss and deduction
for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xi)(C), cause the Per Unit
Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value. 
 (xii) Curative
Allocation. 
 (A) Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations and
other than Section 6.1(d)(xi)), the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Partner
pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related
Curative Allocation not otherwise been provided in this Section 6.1. In exercising its discretion under this Section 6.1(d)(xii)(A), the General Partner may take into account future Required Allocations


  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 74 








 
that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Section 6.1(d)(xii)(A) shall only be made with respect to Required
Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners. 

(B) The General Partner shall, with respect to each taxable period, (1) apply the provisions of
Section 6.1(d)(xii)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xii)(A) among the
Partners in a manner that is likely to minimize such economic distortions. 
 (xiii) Exercise of Noncompensatory
Options. In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s) and as provided in Section 5.4(d)(i), immediately after the conversion of a Limited Partner Interest into Common Units (each such Common Unit a
“Conversion Unit”) upon the exercise of a Noncompensatory Option, the Carrying Value of each Partnership property shall be adjusted to reflect its fair market value immediately after such conversion and any resulting
Unrealized Gain (if the Capital Account of each such Conversion Unit is less than the Per Unit Capital Account for a then Outstanding Initial Common Unit) or Unrealized Loss (if the Capital Account of each such Conversion Unit is greater than the
Per Unit Capital Account for a then Outstanding Initial Common Unit) will be allocated to each Partner holding Conversion Units in proportion to and to the extent of the amount necessary to cause the Capital Account of each such Conversion Unit to
equal the Per Unit Capital Amount for a then Outstanding Initial Common Unit. Any remaining Unrealized Gain or Unrealized Loss will be allocated to the Partners pursuant to Section 6.1(c) and Section 6.1(d).  

(xiv) Corrective and Other Allocations. In the event of any allocation of Additional Book Basis Derivative Items or a
Net Termination Loss, the following rules shall apply: 
 (A) The General Partner shall allocate Additional Book Basis
Derivative Items consisting of depreciation, amortization, depletion or any other form of cost recovery (other than Additional Book Basis Derivative Items included in Net Termination Gain or Net Termination Loss) with respect to any Adjusted
Property to the Unitholders, Pro Rata, to the holders of Incentive Distribution Rights and to the General Partner, all in the same proportion as the Net Termination Gain or Net Termination Loss resulting from the Revaluation Event that gave rise to
such Additional Book Basis Derivative Items was allocated to them pursuant to Section 6.1(c). 
 (B) If a sale or other
taxable disposition of an Adjusted Property, including, for this purpose, inventory (“Disposed of Adjusted 

  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 75 








 
Property”) occurs other than in connection with an event giving rise to Sale Gain or Sale Loss, the General Partner shall allocate (1) items of gross
income and gain (x) away from the holders of Incentive Distribution Rights and the General Partner and (y) to the Unitholders, or (2) items of deduction and loss (x) away from the Unitholders and (y) to the holders of
Incentive Distribution Rights and the General Partner, to the extent that the Additional Book Basis Derivative Items with respect to the Disposed of Adjusted Property (determined in accordance with the last sentence of the definition of Additional
Book Basis Derivative Items) treated as having been allocated to the Unitholders pursuant to this Section 6.1(d)(xiv)(B) exceed their Share of Additional Book Basis Derivative Items with respect to such Disposed of Adjusted Property. For
purposes of this Section 6.1(d)(xiv)(B), the Unitholders shall be treated as having been allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that
would otherwise have been allocated to the Unitholders under the Partnership Agreement (e.g., Additional Book Basis Derivative Items taken into account in computing cost of goods sold would reduce the amount of book income otherwise available for
allocation among the Partners). Any allocation made pursuant to this Section 6.1(d)(xiv)(B) shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xiv) were not in this Agreement and, to the extent
necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations. 

(C) Net Termination Loss in an amount equal to the lesser of (1) such Net Termination Loss and (2) the Aggregate
Remaining Net Positive Adjustments shall be allocated in such manner as is determined by the General Partner that to the extent possible, the Capital Account balances of the Partners (other than with respect to their Series A Preferred Units) will
equal the amount they would have been had no prior Book-Up Events occurred, and any remaining Net Termination Loss shall be allocated pursuant to Section 6.1(c) hereof. In allocating Net Termination Loss pursuant to this
Section 6.1(d)(xiv)(C), the General Partner shall attempt, to the extent possible, to cause the Capital Accounts of the Unitholders (other than with respect to their Series A Preferred Units), on the one hand, and holders of the Incentive
Distribution Rights, on the other hand, to equal the amount they would equal if (i) the Carrying Values of the Partnership’s property had not been previously adjusted in connection with any prior Book-Up Events, (ii) Unrealized Gain
and Unrealized Loss (or, in the case of a liquidation, Liquidation Gain or Liquidation Loss) with respect to such Partnership property were determined with respect to such unadjusted Carrying Values, and (iii) any resulting Net Termination Gain
had been allocated pursuant to Section 6.1(c)(i) (including, for the avoidance of doubt, taking into account the provisions set forth in the last sentence of Section 6.1(c)(i)). 

  
 DOMINION

 76 








 (D) In making the allocations required under this Section 6.1(d)(xiv), the
General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xiv). Without limiting the foregoing, if an Adjusted Property is contributed by the Partnership to another entity
classified as a partnership for U.S. federal income tax purposes (the “lower tier partnership”), the General Partner may make allocations similar to those described in Section 6.1(d)(xiv)(A), (B), and (C) to the extent the
General Partner determines such allocations are necessary to account for the Partnership’s allocable share of income, gain, loss and deduction of the lower tier partnership that relate to the contributed Adjusted Property in a manner that is
consistent with the purpose of this Section 6.1(d)(xiv). 
 (xv) Special Curative Allocation in Event of Liquidation
Prior to Conversion of the Last Outstanding Subordinated Unit. Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations and Section 6.1(d)(xi)), if (A) the Liquidation Date occurs prior to the
conversion of the last Outstanding Subordinated Unit and (B) after having made all other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Capital Account in respect of each
Common Unit does not equal the amount such Capital Account would have been if Section 6.1(c)(iii) and Section 6.1(c)(iv) had not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had
been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable, then items of income, gain, loss and deduction for such taxable period shall be reallocated among all Unitholders (other than with respect to their Series A
Preferred Units) in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior
allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding
sentence provides that, to the extent necessary to achieve the Capital Account balances described above, (x) items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in
which the Liquidation Date occurs shall be reallocated from Unitholders holding Subordinated Units to Unitholders holding Common Units and (y) items of deduction and loss that would otherwise be included in Net Income or Net Loss, as the case
may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from Unitholders holding Common Units to Unitholders holding Subordinated Units. In the event that (1) the Liquidation Date occurs on or before the date
(not including any extension of time prescribed by law) for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the
reallocation of items for the taxable period in which the Liquidation

Date occurs as set forth above in this Section 6.1(d)(xv) fails to achieve the Capital Account balances described above, items of income, gain, loss and deduction that would otherwise be
included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among the General Partner and all Unitholders (other than with respect to their Series A Preferred Units) in a manner that will, to the
maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xv), cause the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior
allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable. 

(xvi) Allocations Regarding Certain Payments Made to or on Behalf of Employees and Other Service Providers. Consistent
with the principles of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to or on behalf of any employee or other service provider of the Partnership Group and such Partner is not
entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then any items of deduction or loss resulting from or attributable to such transfer shall be allocated to the Partner
(or its successor) that made such transfer and such Partner shall be deemed to have contributed such property to the Partnership pursuant to Section 5.12. 

Section 6.2 Allocations for Tax Purposes. 

(a) Except as otherwise provided herein, for U.S. federal income tax purposes, each item of income, gain, loss and deduction
shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1. 

(b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of
income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for U.S. federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations
promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)(E)); provided, that in all events
the General Partner shall apply the “remedial allocation method” in accordance with the principles of Treasury Regulation Section 1.704-3(d). 

(c) The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the
Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized
Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot
reasonably be

taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and
amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other
depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long as such conventions would not have a material adverse effect on the Limited Partners or the Record
Holders of any class or classes of Limited Partner Interests. 
 (d) In accordance with Treasury Regulation Sections
1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this
Section 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such
gains as Recapture Income. 
 (e) All items of income, gain, loss, deduction and credit recognized by the Partnership for
U.S. federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided,
however, that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code. 

(f) Each item of Partnership income, gain, loss and deduction shall, for U.S. federal income tax purposes, be determined for
each taxable period and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the National Securities Exchange on which Partnership Interests are listed or admitted to trading on the first Business Day of each
month; provided, however, such items for the period beginning on the Closing Date and ending on the last day of the month in which the Closing Date occurs shall be allocated to the Partners (including all Persons who acquire Units pursuant to
the Contribution Agreement) as of the closing of the National Securities Exchange on which Partnership Interests are listed or admitted to trading on the last Business Day of the next succeeding month; and provided, further, that gain or loss
on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income, gain, loss or deduction as determined by the General Partner, shall be allocated to the Partners as of the opening of the National Securities
Exchange on which Partnership Interests are listed or admitted to trading on the first Business Day of the month in which such item is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods
of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder. 

(g) Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made
to the beneficial owner of Limited Partner Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by
the General Partner.

 (h) If, as a result of an exercise of a Noncompensatory Option, a Capital Account
reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x). In the event such corrective allocations
are necessary, the Series A Preferred Unitholders agree to remain a partner of the Partnership until such allocations are completed, and the General Partner agrees to make such allocations as soon as practicable, even if such allocations are not
consistent with Section 706 of the Code and any Treasury Regulations thereunder. 
 Section 6.3 Distributions; Characterization
of Distributions; Distributions to Record Holders. 
 (a) The General Partner has adopted a cash distribution policy,
which it may change from time to time without amendment to this Agreement. Distributions will be made as and when declared by the General Partner. 

(b) All amounts of cash and cash equivalents distributed by the Partnership on any date from any source shall be deemed to be
Operating Surplus until the sum of all amounts of cash and cash equivalents theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the Closing Date through the close of the
immediately preceding Quarter. Any remaining amounts of cash and cash equivalents distributed by the Partnership on such date shall, except as otherwise provided in Section 6.5, be deemed to be “Capital Surplus.” All
distributions required to be made under this Agreement or otherwise made by the Partnership shall be made subject to Sections 17-607 and 17-804 of the Delaware Act. 

(c) Notwithstanding Section 6.3(b), in the event of the dissolution and liquidation of the Partnership, all Partnership
assets shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4. 

(d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through any Transfer
Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in
respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise. 

(e) Notwithstanding Section 6.3(b), but subject to Sections 17-607 and 17-804 of the Delaware Act, the General Partner may
cause the Partnership to make special distributions of cash or cash equivalents in connection with contributions of assets by Partners or by Persons who shall become Partners by virtue of such contribution. Such distributions shall not be
subject to, or considered as distributions under, Section 5.11(b)(i)(B), Section 6.1(d)(iii)(A),

the first two sentences of Section 6.3(b), Section 6.4 or Section 6.5. Notwithstanding anything to the contrary set forth in this Agreement (including Section 6.1(d)(iii)(A)),

(a) The Target Distributions, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in
the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Interests. In the event of a distribution of cash or cash equivalents that is deemed to be
from Capital Surplus, the then applicable Target Distributions shall be reduced in the same proportion that the distribution had to the fair market value of the Common Units immediately prior to the announcement of the distribution. If the Common
Units are publicly traded on a National Securities Exchange, the fair market value will be the Current Market Price before the ex-dividend date. If the Common Units are not publicly traded, the fair market value will be determined by the Board of
Directors. 
 (b) The Target Distributions shall also be subject to adjustment pursuant to Section 5.10 and

holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Subordinated Unit shall have all of the rights and obligations
of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Subordinated Units into Common Units pursuant to Section 5.6, the Unitholder holding Subordinated Units shall possess all
of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such converted Subordinated Units, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and
deduction and distributions made with respect to Common Units; provided, however, that such converted Subordinated Units shall remain subject to the provisions of Section 5.4(c)(ii), Section 6.1(d)(x), and Section 6.7(b)
and (c). 
 (b) A Unitholder shall not be permitted to transfer a Subordinated Unit or a Subordinated Unit that has converted
into a Common Unit pursuant to Section 5.6 (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained Subordinated Units or retained converted Subordinated
Units would be negative after giving effect to the allocation under Section 5.4(c)(ii)(B). 
 (c) The Unitholder holding
a Common Unit that has resulted from the conversion of a Subordinated Unit pursuant to Section 5.6 shall not be permitted to transfer such Common Unit to a Person that is not an Affiliate of the holder until such time as the General Partner
determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax
characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(c), the General Partner may take whatever steps are required to provide economic uniformity to such Common Units in preparation for a
transfer of such Common Units, including the application of Sections 5.4(c)(ii) and 6.1(d)(x); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units or the Series A
Preferred Unitholders.

 Section 6.8 Special Provisions Relating to the Holders of IDR Reset Common
Units. 
 (a) A Unitholder shall not be permitted to transfer an IDR Reset Common Unit (other than a transfer to
an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained IDR Reset Common Units would be negative after giving effect to the allocation under Section 5.4(c)(iii). 

(b) A Unitholder holding an IDR Reset Common Unit shall not be permitted to transfer such Common Unit to a Person that is not
an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that upon transfer each such Common Unit should have, as a substantive matter, like intrinsic economic and U.S. federal income tax
characteristics to the transferee, in all material respects, to the intrinsic economic and U.S. federal income tax characteristics of an Initial Common Unit to such transferee. In connection with the condition imposed by this Section 6.8(b),
the General Partner may apply Sections 5.4(c)(iii), 6.1(d)(x) and 6.8(a) or, to the extent not resulting in a material adverse effect on the Unitholders holding Common Units or the Series A Preferred Unitholders, take whatever steps are required to
provide economic uniformity to such Common Units in preparation for a transfer of such IDR Reset Common Units. 
 Section 6.9
Entity-Level Taxation. If legislation is enacted or the official interpretation of existing legislation is modified by a governmental authority, which after giving effect to such enactment or modification, results in a Group Member becoming
subject to federal, state or local or non-U.S. income or withholding taxes in excess of the amount of such taxes due from the Group Member prior to such enactment or modification (including, for the avoidance of doubt, any increase in the rate of
such taxation applicable to the Group Member), then the General Partner may, in its sole discretion, reduce the Target Distributions by the amount of income or withholding taxes that are payable by reason of any such new legislation or
interpretation (the “Incremental Income Taxes”), or any portion thereof selected by the General Partner, in the manner provided in this Section 6.9. If the General Partner elects to reduce the Target
Distributions for any Quarter with respect to all or a portion of any Incremental Income Taxes, the General Partner shall estimate for such Quarter the Partnership Group’s aggregate liability (the “Estimated Incremental Quarterly Tax
Amount”) for all (or the relevant portion

of) such Incremental Income Taxes; provided that any difference between such estimate and the actual liability for Incremental Income Taxes (or the relevant portion thereof) for such
Quarter may, to the extent determined by the General Partner, be taken into account in determining the Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the
Target Distributions, shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of this Section 6.9 times (b) the quotient obtained by dividing (i) cash and cash
equivalents with respect to such Quarter by (ii) the sum of cash and cash equivalents with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner. For purposes of the
foregoing, cash and cash equivalents with respect to a Quarter will be deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

delivery or performance by the General Partner, any Group Member or any Affiliate of any of them of this Agreement or any agreement authorized or permitted under this Agreement (including the exercise by the General Partner or any Affiliate of the
General Partner of the rights accorded pursuant to Article XV) shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Partners or any other Persons under this Agreement (or any other
agreements) or of any duty existing at law, in equity or otherwise. 
 Section 7.2 Replacement of Fiduciary Duties.
Notwithstanding any other provision of this Agreement, to the extent that, at law or in equity, the General Partner or any other Indemnitee would have duties (including fiduciary duties) to the Partnership, to another Partner, to any Person who
acquires an interest in a Partnership 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 expressly set

Partnership Interest and each other Person bound by this Agreement.

partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent the General Partner determines such
action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity
in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner

Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership Group, taken as a whole, in a single transaction or a series of related transactions without the approval of a Unit Majority;
provided, however, that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and
shall not apply to any sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance.

may determine, for (i) all direct and indirect expenses incurred or payments made on behalf of the Partnership Group (including salary, bonus, incentive compensation and other amounts paid to any Person (including Affiliates of the General
Partner, whether pursuant to agreements with Dominion Resources Services, Inc. or otherwise) to perform services for the Partnership Group or for the General Partner in the discharge of its duties to the Partnership Group), and (ii) all other
expenses allocable to the Partnership Group or otherwise incurred by the General Partner in connection with operating the Partnership Group’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner

 (b) The General Partner and its Affiliates may charge any member of the Partnership Group a management fee to the extent
necessary to allow the Partnership Group to reduce the amount of any state franchise or income tax or any tax based upon the revenues or gross margin of any member of the Partnership Group if the tax benefit produced by the payment for such
management fee of such management fee or fees exceeds the amount of such fee or fees. 
 (c) The General Partner, without the
approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership benefit

with, or pursuant to, any benefit plan, program or practice maintained or sponsored by the General Partner or any of its Affiliates, any Group Member or their Affiliates, or any of them, in each case for the benefit of employees, officers,
consultants and directors of the General Partner or its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its
Affiliates any Partnership Interests that the General Partner or such Affiliates are obligated to provide to any employees, officers, consultants and directors pursuant to any such benefit plans, programs or practices. Expenses incurred by the
General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of Partnership Interests purchased by the General Partner or such Affiliates, from the Partnership or
otherwise, to fulfill awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.5(a). Any and all obligations of the General Partner under any benefit plans, programs or practices adopted by the General
Partner as permitted by this Section 7.5(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or
successor to all of the General Partner’s General Partner Interest pursuant to Section 4.6. 
 Section 7.6 Outside
Activities. 
 (a) The General Partner, for so long as it is the General Partner of the Partnership, shall not engage in
any business or activity or incur any debts or liabilities except in connection with or incidental to (i) its performance as general partner or managing member, if any, of one or more Group Members or as described in or contemplated by the
Registration Statement, (ii) the acquiring, owning or disposing of debt securities or equity interests in any Group Member or (iii) the direct or indirect provision of management, advisory, and administrative services to its Affiliates or
to other Persons. 
 (b) 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. No such business interest or activity shall constitute a breach of this
Agreement, any fiduciary or other duty existing at law, in equity or otherwise, or obligation of any type whatsoever to the Partnership or other Group Member, to another Partner, to any Person who acquires an interest in a Partnership Interest or to
any other Person bound by this Agreement. 
 (c) 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,

be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to any Group Member, and such Unrestricted Person (including the General Partner) shall not be
liable to the Partnership or other Group Member, to another Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement for breach of any fiduciary or other duty existing at law, in equity
or otherwise by reason of the fact that such Unrestricted Person (including the General Partner) pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not communicate such opportunity or information to
any Group Member. 
 (d) The General Partner and each of its Affiliates may acquire Units or other Partnership Interests in
addition to those acquired on the Closing Date and, except as otherwise expressly provided in Section 7.11, shall be entitled to exercise, at their option, all rights relating to all Units or other Partnership Interests acquired by them. 

Section 7.7 Indemnification. 

(a) To the fullest extent permitted by law, all Indemnitees shall be indemnified and held harmless by the Partnership from and
against any and all losses, claims, damages, liabilities (joint or several), expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed
claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as an Indemnitee and acting (or refraining to act) in such capacity; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by
a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Agreement, the Indemnitee acted in Bad Faith or engaged in fraud or willful misconduct or, in the case
of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall
not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification. 

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is
indemnified pursuant to Section 7.7(a) in appearing at, participating in or defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by
a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of
any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 7.7.

 (c) The indemnification provided by this Section 7.7 shall be in addition to
any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s
capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

 (d) The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of)
insurance, on behalf of the General Partner, its Affiliates, the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in
connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this
Agreement. 
 (e) For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to
serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes
assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by an Indemnitee with respect to any employee
benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership.

 (f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification
provisions set forth in this Agreement. 
 (g) An Indemnitee shall not be denied indemnification in whole or in part under
this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

(h) The provisions of this Section 7.7 are for the benefit of the Indemnitees and their heirs, successors, assigns,
executors and administrators and shall not be deemed to create any rights for the benefit of any other Persons. 
 (i) No
amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the
Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters
occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

 Section 7.8 Limitation of Liability of Indemnitees. 

(a) Notwithstanding anything to the contrary set forth in this Agreement, any Group Member Agreement, or under the Delaware Act
or any other law, rule or regulation or at equity, no Indemnitee shall be liable for monetary damages or otherwise to the Partnership, to another Partner, to any other Person who acquires an interest in a Partnership Interest or to any other Person
bound by this Agreement, for losses sustained or liabilities incurred, of any kind or character, as a result of its or any of any other Indemnitee’s determinations, act(s) or omission(s) in their capacities as Indemnitees; provided,
however, that an Indemnitee shall be liable for losses or liabilities sustained or incurred by the Partnership, the other Partners, any other Persons who acquire an interest in a Partnership Interest or any other Person bound by this Agreement,
if it is determined by a final and non-appealable judgment entered by a court of competent jurisdiction that such losses or liabilities were the result of the conduct of that Indemnitee acting in Bad Faith or engaging in fraud or willful misconduct
or, with respect to any criminal conduct, with the knowledge that its conduct was unlawful. 
 (b) 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 the General Partner shall not be responsible for any misconduct or negligence on the
part of any such agent appointed by the General Partner if such appointment was not made in Bad Faith. 
 (c) To the extent
that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership, to the Partners, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by
this Agreement, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership, to any Partner, to any Person who acquires an interest in a Partnership
Interest or to any other Person bound by this Agreement for its reliance on the provisions of this Agreement. 
 (d) Any
amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.8 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 

Section 7.9 Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties. 

(a) Whenever the General Partner, acting in its capacity as the general partner of the Partnership, or the Board of Directors
or any committee of the Board of Directors (including the Conflicts Committee) or any Affiliates of the General Partner cause the General Partner to make a determination or take or omit to take any action in such capacity, whether or not under this
Agreement, any Group Member Agreement or any other agreement contemplated hereby, 

  
 DOMINION

 SECOND AMENDED AND

 92 








 
then, unless another lesser standard is provided for in this Agreement, the General Partner, the Board of Directors, such committee or such Affiliates, shall not make such determination, or take
or omit to take such action, in Bad Faith. The foregoing and other lesser standards provided for in this Agreement are the sole and exclusive standards governing any such determinations, actions and omissions of the General Partner, the Board of
Directors, any committee of the Board of Directors (including the Conflicts Committee) and any Affiliate of the General Partner and no such Person shall be subject to any fiduciary duty or other duty or obligation, or any other, different or higher
standard (all of which duties, obligations and standards are hereby waived and disclaimed), under this Agreement any Group Member Agreement or any other agreement contemplated hereby, or under the Delaware Act or any other law, rule or regulation or
at equity. Any such determination, action or omission by the General Partner, the Board of Directors of the General Partner or any committee thereof (including the Conflicts Committee) or of any Affiliates of the General Partner, will for all
purposes be presumed to have been in Good Faith. In any proceeding brought by or on behalf of the Partnership, any Limited Partner, or any other Person who acquires an interest in a Partnership Interest or any other Person who is bound by this
Agreement, challenging such determination, act or omission, the Person bringing or prosecuting such proceeding shall have the burden of proving that such determination, action or omission was not in Good Faith. 

(b) Whenever the General Partner makes a determination or takes or omits to take any action, or any of its Affiliates causes it
to do so, not acting in its capacity as the general partner of the Partnership, whether or not under this Agreement, any Group Member Agreement or any other agreement contemplated hereby, then the General Partner, or such Affiliates causing it to do
so, are entitled, to the fullest extent permitted by law, to make such determination or to take or omit to take such action free of any fiduciary duty or duty of Good Faith, or other duty or obligation existing at law, in equity or otherwise
whatsoever to the Partnership, to another Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement, and the General Partner, or such Affiliates causing it to do so, shall not, to the
fullest extent permitted by law, be required to act in Good Faith or pursuant to any fiduciary or other duty or standard imposed by this Agreement, any Group Member Agreement or any other agreement contemplated hereby or under the Delaware Act or
any other law, rule or regulation or at equity. 
 (c) For purposes of Sections 7.9(a) and (b) of this Agreement,
“acting in its capacity as the general partner of the Partnership” means and is solely limited to, the General Partner exercising its authority as a general partner under this Agreement, other than when it is “acting in its individual
capacity.” For purposes of this Agreement, “acting in its individual capacity” means: (i) any action by the General Partner or its Affiliates other than through the exercise of the General Partner of its authority as a general
partner under this Agreement; and (ii) any action or inaction by the General Partner by the exercise (or failure to exercise) of its rights, powers or authority under this Agreement that are modified by: (A) the phrase “at the option
of the General Partner,” (B) the phrase “in its sole discretion” or “in its discretion” or (iii) some variation of the phrases set forth in clauses (i) and (ii). For the avoidance of doubt, whenever the
General Partner votes, acquires Partnership Interests or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be and be deemed to be “acting in its individual capacity.”

 (d) Whenever a potential conflict of interest exists or arises between the
General Partner or any of its Affiliates, on the one hand, and the Partnership, any Group Member or any Partner, any other Person who acquires an interest in a Partnership Interest or any other Person who is bound by this Agreement on the other
hand, the General Partner may in its discretion (i) submit any resolution course of action with respect to or causing such conflict of interest or transaction for Special Approval or for approval by the vote of a majority of the Common Units
(excluding Common Units owned by the General Partner or its Affiliates) and the Series A Preferred Units voting together as a single class, or (ii) adopt a resolution or course of action that has not received Special Approval or Unitholder
approval. The General Partner is not required in connection with its resolution of any conflict of interest to seek Special Approval or Unitholder approval of such resolution and may determine not to do so in its sole discretion. If any resolution,
course of action or transaction: (A) receives Special Approval; or (B) receives approval of a majority of the Common Units (excluding Common Units owned by the General Partner or its Affiliates), then such resolution, course of action or
transaction shall be conclusively deemed to be approved by the Partnership, all the Partners, each Person who acquires an interest in a Partnership Interest and each other Person who is bound by this Agreement, and shall not constitute a breach of
this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any fiduciary or other duty or obligation existing at law, in equity or otherwise. 

(e) Notwithstanding anything to the contrary in this Agreement, the General Partner and its Affiliates or any other Indemnitee
shall have no duty or obligation, express or implied, to (i) sell or otherwise dispose of any asset of the Partnership Group or (ii) permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except
as may be provided in contracts entered into from time to time specifically dealing with such use. Any determination by the General Partner or any of its Affiliates to enter into such contracts or transactions shall be in its sole discretion. 

(f) The Partners, and each Person who acquires an interest in a Partnership Interest or is otherwise bound by this Agreement
hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a Group Member, to approve actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the
General Partner pursuant to this Section 7.9. 
 (g) For the avoidance of doubt, whenever the Board of Directors, any
committee of the Board of Directors (including the Conflicts Committee), the officers of the General Partner or any Affiliates of the General Partner make a determination on behalf of the General Partner, or cause the General Partner to take or omit
to take any action, whether in the General Partner’s capacity as the general partner of the Partnership or in its individual capacity, the standards of care applicable to the General Partner shall apply to such Persons, and such Persons shall
be entitled to all benefits and rights of the General Partner hereunder, including waivers and modifications of duties, protections and presumptions, as if such Persons were the General Partner hereunder.

 Section 7.10 Other Matters Concerning the General Partner. 

(a) The General Partner may rely, and shall be protected in acting or refraining from acting upon, any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. 

(b) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and
other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the advice or opinion (including an Opinion of Counsel) of such Persons as to matters that the General Partner reasonably believes to be within
such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in Good Faith and in accordance with such advice or opinion. 

(c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of
its or the Partnership’s duly authorized officers, a duly appointed attorney or attorneys-in-fact. 
 Section 7.11 Purchase or
Sale of Partnership Interests. The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Interests; provided that, except as permitted by Section 4.9 or as approved by the Conflicts Committee, the
General Partner may not cause any Group Member to purchase Subordinated Units during the Subordination Period. As long as any Partnership Interests are held by any Group Member, such Partnership Interests shall not be entitled to any vote and shall
not be considered to be Outstanding. 
 Section 7.12 Registration Rights of the General Partner and its Affiliates. 

(a) If (i) the General Partner or any of its Affiliates (including for purposes of this Section 7.12, any Person that
is an Affiliate of the General Partner at the date hereof notwithstanding that it may later cease to be an Affiliate of the General Partner) holds Partnership Interests that it desires to sell and (ii) Rule 144 of the Securities Act (or any
successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Interests (the “Holder”) to dispose of the number of Partnership Interests it desires to
sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and
use all commercially reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Interests covered by such
registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of Partnership Interests specified by the Holder; provided, however, that the Partnership shall
not be required to effect more than two registrations pursuant to this Section 7.12(a) in any

twelve-month period; and provided further, however, that if the General Partner determines that a postponement of the requested registration would be in the best interests of the
Partnership and its Partners due to a pending transaction, investigation or other event, the filing of such registration statement or the effectiveness thereof may be deferred for up to six months, but not thereafter. In connection with any
registration pursuant to the immediately preceding sentence, the Partnership shall (A) promptly prepare and file (1) such documents as may be necessary to register or qualify the securities subject to such registration under the securities
laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of
process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (2) such documents as may be necessary to apply for listing or to
list the Partnership Interests subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and (B) do any and all other acts and things that may be necessary or appropriate to enable the Holder to
consummate a public sale of such Partnership Interests in such states. Except as set forth in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by
the Partnership, without reimbursement by the Holder. 
 (b) If the Partnership shall at any time propose to file a
registration statement under the Securities Act for an offering of Partnership Interests for cash (other than an offering relating solely to a benefit plan), the Partnership shall use all commercially reasonable efforts to include such number or
amount of Partnership Interests held by any Holder in such registration statement as the Holder shall request; provided, that the Partnership is not required to make any effort or take any action to so include the Partnership Interests of the
Holder once the registration statement becomes or is declared effective by the Commission, including any registration statement providing for the offering from time to time of Partnership Interests pursuant to Rule 415 of the Securities Act. If the
proposed offering pursuant to this Section 7.12(b) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holder that in their opinion the
inclusion of all or some of the Holder’s Partnership Interests would adversely and materially affect the timing or success of the offering, the Partnership shall include in such offering only that number or amount, if any, of Partnership
Interests held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth in Section 7.12(c), all costs and expenses of any such
registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder. 

(c) If underwriters are engaged in connection with any registration referred to in this Section 7.12, the Partnership
shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Partnership’s
obligation under Section 7.7, the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless the Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and
any agent thereof (collectively,

(if used prior to the effective date of such registration statement), or in any summary or final prospectus or issuer free writing prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep
the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading;
provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement, such preliminary, summary or final prospectus or free writing prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Partnership by or on
behalf of such Indemnified Person specifically for use in the preparation thereof. 
 (d) The provisions of
Section 7.12(a) and Section 7.12(b) shall be in addition to any other rights to which an the Holders may be entitled under any separate agreement with the Partnership and shall continue to be applicable with respect to the General Partner
(and any of the General Partner’s Affiliates) after it ceases to be a general partner of the Partnership, during a period of two years subsequent to the effective date of such cessation and for so long thereafter as is required for the Holder
to sell all of the Partnership Interests with respect to which it has requested during such two-year period inclusion in a registration statement otherwise filed or that a registration statement be filed; provided, however, that the
Partnership shall not be required to file successive registration statements covering the same Partnership Interests for which registration was demanded during such two-year period. The provisions of Section 7.12(c) shall continue in effect
thereafter. 
 (e) The rights to cause the Partnership to register Partnership Interests pursuant to this Section 7.12
may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such Partnership Interests; provided (i) the Partnership is, within a reasonable time after such transfer, furnished with written notice

terms set forth in this Section 7.12. 
 (f) Any request to register Partnership Interests pursuant to this Section 7.12

connection with the registration of such Partnership Interests.

anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner and any officer of the General Partner authorized by the General Partner to act on behalf of and in the name of
the Partnership has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any authorized contracts on behalf of the Partnership, and such Person shall be entitled to deal
with the General Partner or any such officer as if it were the Partnership’s sole party in interest, both legally and beneficially. Each Limited Partner, each other Person who acquires an interest in a Partnership Interest and each other Person
bound by this Agreement hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available to such Person or Partner to contest, negate or disaffirm any action of the General Partner or any such
officer in connection with any such dealing. In no event shall any Person dealing with the General Partner or any such officer or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire
into the necessity or expedience of any act or action of the General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its
representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full
force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (c) such certificate, document or instrument was duly

 (b) The books of the Partnership shall be maintained, for financial reporting
purposes, on an accrual basis in accordance with U.S. GAAP. The Partnership shall not be required to keep books maintained on a cash basis and the General Partner shall be permitted to calculate cash-based measures, including Operating Surplus and
Adjusted Operating Surplus, by making such adjustments to its accrual basis books to account for non-cash items and other adjustments as the General Partner determines to be necessary or appropriate. 

(c) When calculating the Partnership’s Operating Surplus and Adjusted Operating Surplus: 

(i) the Partnership’s proportionate share of Cove Point’s cash expenditures, cash receipts and cash reserves, as well
as net changes therein or changes in Working Capital Borrowings, will be disregarded; 
 (ii) Adjusted Operating Surplus and
Operating Surplus will be calculated for Cove Point from the Closing Date, as if the pertinent definitions hereof applied to Cove Point, provided that clause (a)(i) in the definition of “Operating Surplus” shall not be applicable.

 (iii) All amounts of cash and cash equivalents distributed by Cove Point on any date from any source shall be deemed to be
distributions from Cove Point’s Operating Surplus until the sum of all amounts of cash and cash equivalents theretofore distributed by Cove Point to its partners (including the Partnership), excluding any distributions deemed to be
distributions from Capital Surplus, equals Cove Point’s Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of cash and cash equivalents distributed by Cove Point in respect of
any Quarter shall be deemed to be distributions of Capital Surplus. If Cove Point makes a distribution of cash or cash equivalents from Operating Surplus and Capital Surplus in respect of any Quarter, each of its partners receiving such distribution
shall be deemed to receive the same proportion of such distribution from Operating Surplus and Capital Surplus, respectively. For the avoidance of doubt, any cash and cash equivalents received by the Partnership as a distribution from Cove
Points’ Operating Surplus shall be treated as Operating Surplus of the Partnership. 
 (iv) For each Quarter, Cove
Point’s Adjusted Operating Surplus shall be allocated among its partners in proportion to the total amount of cash and cash equivalents received by each as a distribution from Cove Point in respect of such Quarter, and the Partnership’s
proportion shall be included in the Partnership’s Adjusted Operating Surplus for such Quarter.

Partner, a report containing unaudited financial statements of the Partnership and such other information as may be required by applicable law, regulation or rule of any National Securities Exchange on which the Units are listed or admitted to
trading, or as the General Partner determines to be necessary or appropriate. 
 (c) The General Partner shall be deemed to

available on such system or (ii) made such report available on any publicly available website maintained by the Partnership.

required for federal, state and local income tax purposes on the basis of the accrual method and the taxable period or year that it is required by law to adopt, from time to time, as determined by the General Partner. If the Partnership is required
to use a taxable period other than a year ending on December 31, the General Partner shall use reasonable efforts to change the taxable period of the Partnership to a year ending on December 31. The tax information reasonably required by
Record Holders for federal, state and local income tax reporting purposes with respect to a taxable period shall be furnished to them within 90 days of the close of the calendar year in which the Partnership’s taxable period ends. The

 Section 9.2 Tax Elections. 

(a) The Partnership shall make the election under Section 754 of the Code in accordance with applicable regulations
thereunder, subject to the reservation of the right to seek to revoke any such election upon the General Partner’s determination that such revocation is in the best interests of the Limited Partners. Notwithstanding any other provision herein
contained, for the purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Limited Partner Interest
will be deemed to be the lowest Closing Price of the Limited Partner Interests on any National Securities Exchange on which such Limited Partner Interests are listed or admitted to trading during the calendar month in which such transfer is deemed
to occur pursuant to Section 6.2(f) without regard to the actual price paid by such transferee. 
 (b) Except as
otherwise provided herein, the General Partner shall determine whether the Partnership should make any other elections permitted by the Code. 

Section 9.3 Tax Controversies. Subject to the provisions hereof, the General Partner is designated as the Tax Matters Partner (as
defined in Section 6231(a)(7) of the Code as in effect prior to the enactment of the Bipartisan Budget Act of 2015), and the “partnership representative” (as defined in Section 6223 of the Code following the enactment of the
Bipartisan Budget Act of 2015) 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 and costs associated therewith. In its capacity as “partnership representative,” the General Partner shall exercise any and all authority of
the “partnership representative” under the Code, including, without limitation, (i) binding the Partnership and its Partners with respect to tax matters and (ii) determining whether to make any available election under
Section 6226 of the Code. Each Partner agrees to cooperate with the General Partner and to do or refrain from doing any or all things reasonably required by the General Partner to conduct such proceedings. Each Partner agrees that notice of or
updates regarding tax controversies shall be deemed conclusively to have been given or made by the General Partner if the Partnership has either (a) filed the information for which notice is required with the Commission via its Electronic Data
Gathering, Analysis and Retrieval system and such information is publicly available on such system or (b) made the information for which notice is required available on any publicly available website maintained by the Partnership, whether or
not such Partner remains a Partner in the Partnership at the time such information is made publicly available. The General Partner may amend the provisions of this Agreement as determined appropriate in order to minimize the potential U.S. federal
and state or local income tax consequences to current and former Limited Partners, and for the proper administration of the Partnership, upon any amendment to the provisions of Subchapter C of Chapter 63 of Subtitle A of the Code, as enacted by the
Bipartisan Budget Act of 2015, or the promulgation of regulations or publication of other administrative guidance thereunder.

 Section 9.4 Withholding; Tax Payments.

distribution of cash to such Partners or as a general expense of the Partnership, as determined appropriate under the circumstances by the General Partner. 

(b) Notwithstanding any other provision of this Agreement, the General Partner is authorized to take any action that may be
required to cause the Partnership and other Group Members to comply with any withholding requirements established under the Code or any other federal, state or local law including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the
extent that the Partnership is required or elects to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income or from a distribution to any Partner (including by reason of Section 1446 of
the Code), the General Partner may treat the amount withheld as a distribution of cash pursuant to Section 6.3 in the amount of such withholding from such Partner.

Limited Partner without acquiring a Limited Partner Interest and until such Person is reflected in the books and records of the Partnership as the Record Holder of such Limited Partner Interest. The rights and obligations of a Person who is a

Unitholders holding a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and Series A Preferred Units voting together as a single class and the General Partner delivers to the Partnership
an Opinion of Counsel (“Withdrawal Opinion of Counsel”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability under the Delaware Act of any

prevailing Eastern Time, on June 30, 2024, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Unitholders, such withdrawal to take effect on the
date specified in such notice; (iii) at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this

time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership
upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or managing member, if any, to the extent applicable, of the other Group Members. If the General Partner gives a notice of
withdrawal pursuant to Section 11.1(a)(i), a Unit Majority may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor
general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If, prior to the effective date of the General Partner’s withdrawal pursuant to
Section 11.1(a)(i), a successor is not selected by the Unitholders as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 12.1 unless the
business of the Partnership is continued pursuant to Section 12.2. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.2. 

Section 11.2 Removal of the General Partner. The General Partner may be removed if such removal is approved by the Unitholders
holding at least 66 2/3% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class. Any such action by such holders for removal of the General Partner must also provide for the election of a
successor General Partner by the Unitholders holding a majority of the Outstanding Common Units, voting as a class, and a majority of the Outstanding Subordinated Units, voting as a class (including, in each case, Units held by the General Partner
and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General
Partner as general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the
terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner
is a general partner or a managing member. The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal
Opinion of Counsel. Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2.

 Section 11.3 Interest of Departing General Partner and Successor General Partner.

 (a) In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate
this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if the successor General Partner is elected in accordance with the terms of Section 11.1 or
Section 11.2, the Departing General Partner shall have the option, exercisable prior to the effective date of the withdrawal or removal of such Departing General Partner, to require its successor to purchase its General Partner Interest and its
or its Affiliates’ general partner interest (or equivalent interest), if any, in the other Group Members and all of its or its Affiliates’ Incentive Distribution Rights (collectively, the “Combined Interest”) in
exchange for an amount in cash equal to the fair market value of such Combined Interest, such amount to be determined and payable as of the effective date of its withdrawal or removal. If the General Partner is removed by the Unitholders under
circumstances where Cause exists or if the General Partner withdraws under circumstances where such withdrawal violates this Agreement, and if a successor General Partner is elected in accordance with the terms of Section 11.1 or
Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner), such successor shall have the option, exercisable prior to the effective date
of the withdrawal or removal of such Departing General Partner (or, in the event the business of the Partnership is continued, prior to the date the business of the Partnership is continued), to purchase the Combined Interest for such fair market
value of such Combined Interest. In either event, the Departing General Partner shall be entitled to receive all reimbursements due such Departing General Partner pursuant to Section 7.5, including any employee-related liabilities (including
severance liabilities), incurred in connection with the termination of any employees employed by the Departing General Partner or its Affiliates (other than any Group Member) for the benefit of the Partnership or the other Group Members. 

For purposes of this Section 11.3(a), the fair market value of the Combined Interest shall be determined by agreement between the
Departing General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s withdrawal or removal, by an independent investment banking firm or other independent expert selected
by the Departing General Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other
independent expert within 45 days after the effective date of such withdrawal or removal, then the Departing General Partner shall designate an independent investment banking firm or other independent expert, the Departing General Partner’s
successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent investment
banking firm or other independent expert shall determine the fair market value of the Combined Interest. In making its determination, such third independent investment banking firm or other independent expert may consider the value of the Units,
including the then current trading price of Units on any National Securities Exchange on which Units are then listed or admitted to trading, the value of the Partnership’s assets, the rights and obligations of the Departing General Partner, the
value of the Incentive Distribution Rights and the General Partner Interest and other factors it may deem relevant.

 (b) If the Combined Interest is not purchased in the manner set forth in
Section 11.3(a), the Departing General Partner (and its Affiliates, if applicable) shall become a Limited Partner and the Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other
independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the
Departing General Partner as to all debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest to Common
Units will be characterized as if the Departing General Partner (and its Affiliates, if applicable) contributed the Combined Interest to the Partnership in exchange for the newly issued Common Units. 

(c) If a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the
business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner) and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the
successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to the product of (x) the quotient obtained by dividing (A) the Percentage Interest of the
General Partner Interest of the Departing General Partner by (B) a percentage equal to 100% less the Percentage Interest of the General Partner Interest of the Departing General Partner and (y) the Net Agreed Value of the
Partnership’s assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to its Percentage Interest of all Partnership allocations and distributions to which the Departing General
Partner was entitled. In addition, the successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner’s admission, the successor General Partner’s interest in
all Partnership distributions and allocations shall be its Percentage Interest. 
 Section 11.4 Conversion of Subordinated
Units. Notwithstanding any provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist, the Subordinated Units held by any Person will immediately and
automatically convert into Common Units on a one-for-one basis, provided (i) neither such Person nor any of its Affiliates voted any of its Units in favor of the removal and (ii) such Person is not an Affiliate of the successor
General Partner; provided, however, that such converted Subordinated Units shall remain subject to the provisions of Section 5.4(c)(ii), Section 6.1(d)(x), Section 6.7(b) and Section 6.7(c). 

Section 11.5 Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership;
provided, however, that when a transferee of a Limited Partner’s Limited Partner Interest becomes a Record Holder of the Limited Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited
Partner with respect to the Limited Partner Interest so transferred.

Majority may elect to continue the business of the Partnership on the same terms and conditions set forth in this Agreement by appointing as a successor General Partner a Person approved by a Unit Majority. Unless such an election is made within the
applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then: 

(i) the Partnership shall continue without dissolution unless earlier dissolved in accordance with this Article XII; 

(ii) if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall
be treated in the manner provided in Section 11.3; and

 provided, that the right of a Unit Majority to approve a successor General Partner and to continue the
business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability under the Delaware Act of any
Limited Partner and (y) neither the Partnership nor any Group Member would be treated as an association taxable as a corporation or otherwise be taxable as an entity for U.S. federal income tax purposes upon the exercise of such right to
continue (to the extent not already so treated or taxed). 
 Section 12.3 Liquidator. Upon dissolution of the Partnership,
unless the business of the Partnership is continued pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such
compensation for its services as may be approved by holders of a majority of the Outstanding Common Units and Subordinated Units, voting as a single class. The Liquidator (if other than the General Partner) shall agree not to resign at any time
without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of a majority of the Outstanding Common Units and Subordinated Units, voting as a single class. Upon dissolution,
removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of a majority of the
Outstanding Common Units and Subordinated Units, voting as a single class. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved
in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the
powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in
Section 7.4) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Partnership as provided for herein. 

Section 12.4 Liquidation. The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and
otherwise wind up its affairs in such manner and over such period as determined by the Liquidator, subject to Section 17-804 of the Delaware Act and the following: 

(a) The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as
the Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and
contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may defer liquidation or distribution of the Partnership’s assets for a

reasonable time if it determines that an immediate sale or distribution of all or some of the Partnership’s assets would be impractical or would cause undue loss to the Partners. The
Liquidator may distribute the Partnership’s assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners. 

(b) Liabilities of the Partnership include amounts owed to the Liquidator as compensation for serving in such capacity (subject
to the terms of Section 12.3) and amounts to Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable,
the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional
liquidation proceeds. 
 (c) All property and all cash in excess of that required to discharge liabilities as provided in
Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (including the
allocation provided for under Section 6.1(d)(xi)(C), which allocates items of gross income, gain, loss and deduction among the Partners to the maximum extent possible to provide a preference in liquidation to the Capital Account of the Series A
Preferred Units over the Capital Accounts of Series A Junior Securities, but excluding adjustments made by reason of distributions pursuant to this Section 12.4(c)) for the taxable period of the Partnership during which the liquidation of the
Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable period (or, if later, within 90 days after said date
of such occurrence); provided that any cash or cash equivalents available for distribution under this Section 12.4(c) shall be distributed with respect to the Series A Preferred Units and Series A Senior Securities (up to the positive
balances in the associated Capital Accounts) prior to any distribution of cash or cash equivalents with respect to the Series A Junior Securities. 

Section 12.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and
property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State
of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken. 
 Section 12.6
Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions
of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets. 

Section 12.7 Waiver of Partition. To the maximum extent permitted by law, each Partner hereby waives any right to partition of the
Partnership property.

otherwise taxed as entities for U.S. federal income tax purposes;

(A) satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation of any federal or state agency or judicial authority or contained in any federal or state statute (including the Delaware
Act) or (B) facilitate the trading of the Units (including the division of any class or classes of Outstanding Units into different classes to facilitate uniformity of tax consequences within such classes of Units) or comply with any rule,
regulation, guideline or requirement of any National Securities Exchange on which the Units are or will be listed or admitted to trading, (iii) to be necessary or appropriate in connection with action taken by the General Partner pursuant to
Section 5.8 or (iv) is required to effect the intent expressed in the Registration Statement or the intent of the provisions of this Agreement or is otherwise contemplated by this Agreement;

 (f) an amendment that is necessary, in the Opinion of Counsel, to prevent
the Partnership, or the General Partner or its directors, officers, trustees or agents from in any manner being subjected to the provisions of the Investment Company Act of 1940, as amended, the Investment Advisers Act of 1940, as amended, or
“plan asset” regulations adopted under the Employee Retirement Income Security Act of 1974, as amended, regardless of whether such are substantially similar to plan asset regulations currently applied or proposed by the U.S. Department of
Labor; 
 (g) an amendment that the General Partner determines to be necessary or appropriate in connection with the
creation, authorization or issuance of any class or series of Partnership Interests and Derivative Instruments pursuant to Section 5.5;

Section 2.4 or Section 7.1(a);

Section 13.2 Amendment Procedures. Amendments to this Agreement may be proposed only by the General Partner. To the fullest extent
permitted by law, the General Partner shall have no duty or obligation to propose or approve any amendment to this Agreement and may decline to do so in its sole discretion. An amendment shall be effective upon its approval by the General Partner
and, except as otherwise provided by Section 13.1 or Section 13.3, a Unit Majority, unless a greater or different percentage is required under this Agreement or by Delaware law. Each proposed amendment that requires the approval of the
holders of a specified percentage of Outstanding Units or class of Limited Partners shall be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, the General Partner shall seek the written
approval of the requisite percentage of Outstanding Units or class of Limited Partners or call a meeting of the Unitholders to consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of
any amendments. The General Partner shall be deemed to have notified all Record Holders as required by this Section 13.2 if it has either (a) filed such amendment with the Commission via

maintained by the Partnership. 
 Section 13.3 Amendment Requirements. 

(a) Notwithstanding the provisions of Section 13.1 (other than Section 13.1(d)(iv)) and Section 13.2, no
provision of this Agreement (other than Section 11.2 or Section 13.4) that establishes a percentage of Outstanding Units (including Units deemed owned by the General Partner) or class of Limited Partners or requires a vote or approval of
Partners (or a subset of Partners) holding a specified Percentage Interest to take any action shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of reducing or increasing such percentage, unless such
amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate Outstanding Units constitute not less than the voting requirement sought to be reduced or increased, as applicable, or the
affirmative vote of Partners whose aggregate Percentage Interests constitute not less than the voting requirement sought to be reduced or increased, as applicable. 

(b) Notwithstanding the provisions of Section 13.1 (other than Section 13.1(d)(iv)) and Section 13.2, no
amendment to this Agreement may (i) enlarge the obligations of (including requiring any holder of a class of Partnership Interests to make additional Capital Contributions to the Partnership) any Limited Partner without its consent, unless such
shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c), or (ii) enlarge the obligations of, restrict, change or modify in any way any action by or rights of, or reduce in any way the amounts
distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent may be given or withheld at its option. 

(c) Except as provided in Section 14.3 or Section 13.1, any amendment that would have a material adverse effect on
the rights or preferences of any class of Partnership Interests in relation to other classes of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class affected. If the
General Partner determines an amendment does not satisfy the requirements of Section 13.1(d)(i) because it adversely affects one or more classes of Partnership Interests, as compared to other classes of Partnership Interests, in any material
respect, such amendment shall only be required to be approved by the adversely affected class or classes. 
 (d)
Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least
90% of the Percentage Interests of all Limited Partners voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect that such amendment will not affect the limited liability of any Limited Partner under applicable
partnership law of the state under whose laws the Partnership is organized. 
 (e) Except as provided in Section 13.1,
this Section 13.3 shall only be amended with the approval of Partners (including the General Partner and its Affiliates) holding at least 90% of the Percentage Interests of all Limited Partners.

 Section 13.4 Special Meetings. All acts of Limited Partners to be taken pursuant to
this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of the class or classes for
which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the specific
purposes for which the special meeting is to be called and the class or classes of Units for which the meeting is proposed. No business may be brought by any Limited Partner before such special meeting except the business listed in the related
request. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements
governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be
held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the time notice of the meeting is given as provided in Section 16.1. Limited Partners shall not vote on matters that would
cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or the law of any other
state in which the Partnership is qualified to do business. 
 Section 13.5 Notice of a Meeting. Notice of a meeting called
pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. The notice shall be
deemed to have been given at the time when deposited in the mail or sent by other means of written communication. 
 Section 13.6
Record Date. For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11 the General Partner may set a Record
Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are
listed or admitted to trading or U.S. federal securities laws, in which case the rule, regulation, guideline or requirement of such National Securities Exchange or U.S. federal securities laws shall govern) or (b) in the event that approvals
are sought without a meeting, the date by which Limited Partners are requested in writing by the General Partner to give such approvals. If the General Partner does not set a Record Date, then (i) the Record Date for determining the Limited
Partners entitled to notice of or to vote at a meeting of the Limited Partners shall be the close of business on the day next preceding the day on which notice is given, and (ii) the Record Date for determining the Limited Partners entitled to
give approvals without a meeting shall be the date the first written approval is deposited with the Partnership in care of the General Partner in accordance with Section 13.11.

 Section 13.7 Postponement and Adjournment. Prior to the date upon which any meeting
of Limited Partners is to be held, the General Partner may postpone such meeting one or more times for any reason by giving notice to each Limited Partner entitled to vote at the meeting so postponed of the place, date and hour at which such meeting
would be held. Such notice shall be given not fewer than two days before the date of such meeting and otherwise in accordance with this Article XIII. When a meeting is postponed, a new Record Date need not be fixed unless such postponement shall be
for more than 45 days. Any meeting of Limited Partners may be adjourned by the General Partner one or more times for any reason, including the failure of a quorum to be present at the meeting with respect to any proposal or the failure of any
proposal to receive sufficient votes for approval. No Limited Partner vote shall be required for any adjournment. A meeting of Limited Partners may be adjourned by the General Partner as to one or more proposals regardless of whether action has been
taken on other matters. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the
adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days
or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII. 

Section 13.8 Waiver of Notice; Approval of Meeting; Approval of Minutes. The transaction of business at any meeting of Limited
Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting
shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully
called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at
the meeting. 
 Section 13.9 Quorum and Voting. The holders of a majority, by Percentage Interest, of Partnership Interests of
the class or classes for which a meeting has been called (including Partnership Interests deemed owned by the General Partner) represented in person or by proxy shall constitute a quorum at a meeting of Partners of such class or classes unless any
such action by the Partners requires approval by holders of a greater Percentage Interest, in which case the quorum shall be such greater Percentage Interest. At any meeting of the Partners duly called and held in accordance with this Agreement at
which a quorum is present, the act of holders of Partnership Interests that, in the aggregate, represent a majority of the Percentage Interest of those present in person or by proxy at such meeting shall be deemed to constitute the act of all
Partners, unless a greater or different percentage or class vote is required with respect to such action under the provisions of this Agreement, in which case the act of the holders of Partnership 

  
 DOMINION
MIDSTREAM PARTNERS, LP 
 SECOND AMENDED AND
RESTATED AGREEMENT OF LIMITED PARTNERSHIP 
 115 








 
Interests that in the aggregate represent at least such greater or different percentage or the act of the Limited Partners holding the requisite percentage of the necessary class, shall be
required; provided, however, that if, as a matter of law or provision of this Agreement, approval by plurality vote of Partners (or any class thereof) is required to approve any action, no minimum quorum shall be required. The Partners
present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Partners to leave less than a quorum, if any action taken (other than adjournment) is
approved by holders of the required Percentage Interest or class of Limited Partners specified in this Agreement. 
 Section 13.10
Conduct of a Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to
vote, the existence of a quorum, the satisfaction of the requirements of Section 13.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or
during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership
maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of
approvals in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the
revocation of approvals in writing. 
 Section 13.11 Action Without a Meeting. If authorized by the General Partner, any action
that may be taken at a meeting of the Limited Partners may be taken without a meeting, without a vote and without prior notice, if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the
minimum percentage, by Percentage Interest, of the Partnership Interests of the class or classes for which a meeting has been called (including Partnership Interests deemed owned by the General Partner), as the case may be, that would be necessary
to authorize or take such action at a meeting at which all the Limited Partners entitled to vote at such meeting were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities
Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to
the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time
period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partners, the Partnership shall be deemed to have failed to receive a ballot
for the Units that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until
(a) they are deposited with the Partnership in care of the General Partner and (b) an 

  
 DOMINION
MIDSTREAM PARTNERS, LP

Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not
cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise permissible under the
state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. Nothing contained in this Section 13.11 shall be deemed to require the General Partner to solicit all Limited Partners in connection with a
matter approved by the holders of the requisite percentage of Units acting by written consent without a meeting. 
 Section 13.12
Right to Vote and Related Matters. 
 (a) Only those Record Holders of the Outstanding Units on the Record Date set
pursuant to Section 13.6 shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which the holders of the Outstanding Units have the right to vote or to act. All references in this
Agreement to votes of, or other acts that may be taken by, the Outstanding Units shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Units. 

(b) With respect to Units that are held for a Person’s account by another Person (such as a broker, dealer, bank, trust
company or clearing corporation, or an agent of any of the foregoing), in whose name such Units are registered, such other Person shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such
Persons provides otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this
Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3. 

Section 13.13 Voting of Incentive Distribution Rights. 

(a) For so long as a majority of the Incentive Distribution Rights are held by the General Partner and its Affiliates, the
holders of the Incentive Distribution Rights shall not be entitled to vote such Incentive Distribution Rights on any Partnership matter except as may otherwise be required by law and the holders of the Incentive Distribution Rights, in their
capacity as such, shall be deemed to have approved any matter approved by the General Partner. 
 (b) If less than a majority
of the Incentive Distribution Rights are held by the General Partner and its Affiliates, the Incentive Distribution Rights will be entitled to vote on all matters submitted to a vote of Unitholders, other than amendments and other matters that the
General Partner determines do not adversely affect the holders of the Incentive Distribution Rights as a whole in any material respect. On any matter in which the holders of Incentive Distribution Rights are entitled to vote, such holders will vote
together with the Subordinated Units, prior to the end of the Subordination Period, or together with the Common Units, thereafter, in either case as a single class except as otherwise required by Section 13.3(c), and such Incentive Distribution
Rights shall be treated in all respects as Subordinated Units or 

  
 DOMINION

 117 








 
Common Units, as applicable, when sending notices of a meeting of Limited Partners to vote on any matter (unless otherwise required by law), calculating required votes, determining the presence
of a quorum or for other similar purposes under this Agreement. The relative voting power of the Incentive Distribution Rights and the Subordinated Units or Common Units, as applicable, will be set in the same proportion as cumulative cash
distributions, if any, in respect of the Incentive Distribution Rights for the four consecutive Quarters prior to the record date for the vote bears to the cumulative cash distributions in respect of such class of Units for such four Quarters. 

(c) In connection with any equity financing, or anticipated equity financing, by the Partnership of an Expansion Capital
Expenditure, the General Partner may, without the approval of the holders of the Incentive Distribution Rights, temporarily or permanently reduce the amount of Incentive Distributions that would otherwise be distributed to such holders,
provided that in the judgment of the General Partner, such reduction will be in the long-term best interest of such holders. 

ARTICLE XIV

limited liability companies, statutory trusts or associations, real estate investment trusts, common law trusts or unincorporated businesses, including a partnership (whether general or limited (including a limited liability partnership)) or convert

necessary or appropriate.

without Limited Partner approval, to convert the Partnership or any Group Member into a new limited liability entity, to merge the Partnership or any Group Member into, or convey all of the Partnership’s assets to, another limited liability
entity that shall be newly formed and shall have no assets, liabilities or operations at the time of such merger or conveyance other than those it receives from the Partnership or other Group Member if (i) the General Partner has received an
Opinion of Counsel that the merger or conveyance, as the case may be, would not result in the loss of the limited liability under the Delaware Act of any Limited Partner or cause the Partnership or any Group Member to be treated as an association
taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already treated as such), (ii) the sole purpose of such merger, or conveyance is to effect a mere change in the legal form of
the Partnership into another limited liability entity and (iii) the governing instruments of the new entity provide the Limited Partners and the General Partner with substantially the same rights and obligations as are herein contained.

be, would not result in the loss of the limited liability under the Delaware Act of any Limited Partner or cause the Partnership or any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for
U.S. federal income tax purposes (to the extent not already treated as such), (ii) the merger or consolidation would not result in an amendment to this Agreement, other than any amendments that could be adopted pursuant to Section 13.1,

Partnership elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the General Partner shall deliver to the Transfer Agent notice of such election to purchase (the “Notice of Election
to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Limited Partner Interests of such class (as of a Record Date selected by the General Partner) at least 10,
but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be filed and distributed as may be required by the Commission or any National Securities Exchange on which such Limited Partner Interests are

the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Certificate shall not have been surrendered for
purchase, all rights of the holders of such Limited Partner Interests shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner Interests therefor, without
interest, upon surrender to the Transfer Agent of the Certificates representing such Limited Partner Interests in the case of Limited Partner Interests evidenced by Certificates, and such Limited Partner Interests shall thereupon be deemed to be
transferred to the General Partner, its Affiliate or the Partnership, as the case may be, on the record books of the Transfer Agent and the Partnership, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case
may be, shall be deemed to be the owner of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the owner of such Limited Partner Interests. 

(c) In the case of Limited Partner Interests evidenced by Certificates, at any time from and after the Purchase Date, a holder
of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent in exchange for payment of the amount described in

an affiliate (as defined in Rule 144 promulgated under the Securities Act) of the Partnership, the date on which such Holder ceases to be an affiliate of the Partnership. For the avoidance of doubt, the provisions of this Section 1.02 do
not modify the transfer restrictions applicable to the Holders set forth in Section 5.11(b)(viii) of, and elsewhere in, the Partnership Agreement. 

ARTICLE II. 

REGISTRATION RIGHTS 

Section 2.01 Shelf Registration. 

(a) Shelf Registration Statements. 

(i) The Partnership shall use its commercially reasonable efforts to (i) prepare and file an initial registration
statement under the Securities Act to permit the resale of the PIPE Unit Registrable Securities from time to time as permitted by Rule 415 (or any similar provision adopted by the Commission then in effect) of the Securities Act (a “PIPE
Unit Registration Statement”) and (ii) cause such initial Registration Statement to become effective no later than the Target Effective Date for the PIPE Unit Registrable Securities. 

(ii) The Partnership shall use its commercially reasonable efforts to (i) prepare and file an initial registration
statement under the Securities Act (or an amendment to the Registration Statement filed pursuant to Section 2.01(a)(i)) to permit the resale of the Conversion Unit Registrable Securities from time to time as permitted by Rule 415 (or any
similar provision adopted by the Commission then in effect) of the Securities Act (a “Conversion Unit Registration Statement”) and (ii) cause such initial Registration Statement or such amendment to become effective no
later than the Target Effective Date for the Conversion Unit Registrable Securities. 
 (iii) If the Purchasers own more than
50% of the number of Series A Preferred Units purchased under the Unit Purchase Agreement as of the date of such request, then, upon the written request of Purchasers holding a majority of the Series A Preferred Unit Registrable Securities (which
request may be given at least 180 days before the fifth anniversary of the date hereof), the Partnership shall use its commercially reasonable efforts to prepare and file, and cause to become effective no later than 180 days following receipt of
such notice (the 180th date being the Target Effective Date for the Series A Preferred Registrable Securities), an initial Registration Statement (or an amendment to the Registration Statement
filed pursuant to Section 2.01(a)(i) or Section 2.01(a)(ii)) to permit the resale of the Series A Preferred Unit Registrable Securities from time to time as permitted by Rule 415 (or any similar provision adopted by the
Commission then in effect) of the Securities Act (a “Preferred Unit Registration Statement” and, each Preferred Unit Registration Statement, PIPE Unit Registration Statement or Conversion


  
 6 








 
Unit Registration Statement, a “Registration Statement”); provided, however, that the obligation of the Partnership to use such commercially reasonable
efforts to prepare, file, and cause to become effective such Registration Statement shall terminate immediately and be of no further force and effect if, at any time, the Purchasers fail to own more than 50% of the number of Series A Preferred Units
purchased under the Unit Purchase Agreement. 
 (iv) The Partnership will use its commercially reasonable efforts to cause
the Registration Statements filed pursuant to Section 2.01(a) to be continuously effective under the Securities Act, with respect to any Holder, until the earliest to occur of the following: (A) the date on which there are no longer
any Registrable Securities outstanding and (B) (1) with respect to Conversion Unit Registrable Securities and Series A Preferred Unit Registrable Securities, the later of (I) the second anniversary of the date on which all Series A
Preferred Units have been converted into Common Units pursuant to Article V of the Partnership Agreement and, (II) if such Holder is an affiliate (as defined in Rule 144 promulgated under the Securities Act) of the Partnership, the date on which
such Holder ceases to be an affiliate of the Partnership, and (2) with respect to PIPE Unit Registrable Securities, on the later of (I) the fifth anniversary of the date on which the PIPE Unit Registration Statement is effective and, (II)
if such Holder is an affiliate (as defined in Rule 144 promulgated under the Securities Act) of the Partnership, the date on which such Holder ceases to be an affiliate of the Partnership (in each case of clause (A) or (B) the
“Effectiveness Period”). A Registration Statement filed pursuant to Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be selected by the Partnership; provided that,
if the Partnership is then eligible, it shall file such Registration Statement on Form S-3. A Registration Statement when declared effective (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 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 (and, in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that a Registration Statement becomes effective,
but in any event within three Business Days of such date, the Partnership shall provide the Holders with written notice of the effectiveness of such Registration Statement. 

(b) Failure to Become Effective. If a Registration Statement required by Section 2.01(a) does not become or is not
declared effective by the applicable Target Effective Date, then each Holder shall be entitled to a payment (with respect to each of the Holder’s Registrable Securities which are included in such Registration Statement), as liquidated damages
and not as a penalty, of (i) for each non-overlapping 30-day period for the first 60 days following the applicable Target Effective Date, an amount equal to 0.25% of the applicable Liquidated Damages Multiplier, and (ii) for each
non-overlapping 30-day period beginning on the 61st day following the applicable Target Effective Date, an amount equal to the amount set forth in clause (i) plus an additional 0.25% of the applicable Liquidated Damages Multiplier for each
subsequent 60 days (i.e., 0.5% for 61-120 days, 0.75% for 121-180 days, and 1.0% thereafter), up to a maximum amount equal to 1.0% of the applicable Liquidated Damages Multiplier per non-overlapping 30-day period (the “Liquidated
Damages”), until such time as such 

  
 7 








 
Registration Statement is declared or becomes effective or there are no longer any Registrable Securities outstanding. The Liquidated Damages shall be payable within 10 Business Days after the
end of each such 30-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 30 days accruing during any period for which
a Holder is entitled to Liquidated Damages hereunder. 
 (c) Waiver of Liquidated Damages. If the Partnership is unable to
cause (i) the PIPE Unit Registration Statement to become effective on or before the applicable Target Effective Date, then the Partnership may request a waiver of the Liquidated Damages with respect thereto, which may be granted by the consent
of the Holders of at least 75% of the PIPE Unit Registrable Securities, in their sole discretion, and which such waiver shall apply to all the Holders of PIPE Unit Registrable Securities included on such Registration Statement or (ii) the
Conversion Unit Registration Statement or the Preferred Unit Registration Statement to become effective on or before the applicable Target Effective Date, then the Partnership may request a waiver of the Liquidated Damages with respect thereto,
which may be granted by the consent of Holders of at least the Registrable Securities Required Voting Percentage, in their sole discretion, and which such waiver shall apply to all the Holders of Registrable Securities included on such Registration
Statement. 
 (d) Delay Rights. Notwithstanding anything to the contrary contained herein, the Partnership 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 such Registration Statement (in which event the Selling Holder shall
suspend sales of the Registrable Securities pursuant to such Registration Statement) if (i) the Partnership is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and the Partnership determines in good
faith that the Partnership’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in such Registration Statement or (ii) the Partnership has
experienced some other material non-public event, the disclosure of which at such time, in the good faith judgment of the Partnership, would materially and adversely affect the Partnership; provided, however, that in no event shall the
Selling Holders be suspended from selling Registrable Securities pursuant to such Registration Statement for a period that exceeds an aggregate of 60 days in any 180-day period or 90 days in any 365-day period. Upon disclosure of such information or
the termination of the condition described above, the Partnership shall provide prompt notice to the Selling Holders whose Registrable Securities are included in such Registration Statement, and shall promptly terminate any suspension of sales it
has put into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement. 

Section 2.02 Piggyback Registration. 

(a) Participation. If at any time the Partnership proposes to file (i) a Registration Statement (other than a Registration
Statement contemplated by Section 2.01(a)) on behalf of any other Holder, other than DRI or any of its Affiliates, who has registration rights related to an Underwritten Offering undertaken pursuant to Section 2.03
(“Other Holder”), or (ii) a prospectus supplement relating to the sale of Common Units by any Other Holders to an 

  
 8 








 
effective “automatic” registration statement, so long as the Partnership is a WKSI at such time or, whether or not the Partnership is a WKSI, so long as the Common Unit Registrable
Securities were previously included in the underlying shelf Registration Statement or are included on an effective Registration Statement, or in any case in which Holders may participate in such offering without the filing of a post-effective
amendment, in each case, for the sale of Common Units by Other Holders in an Underwritten Offering undertaken pursuant to Section 2.03, then the Partnership shall give not less than four Business Days’ notice (including notification
by electronic mail) (the “Piggyback Notice”) of such proposed Underwritten Offering to each Holder (together with its Affiliates) owning Common Unit Registrable Securities and such Piggyback Notice shall offer such Holder the
opportunity to include in such Underwritten Offering such number of Common Unit Registrable Securities (the “Included Registrable Securities”) as such Holder may request in writing (a “Piggyback
Registration”); provided, however, that the Partnership shall not be required to offer such opportunity (A) to such Holders if the Holders, together with their Affiliates, do not offer a minimum of $25 million of
Common Unit Registrable Securities, in the aggregate (determined by multiplying the number of Common Unit Registrable Securities owned by the Average VWAP for the 10 Trading Days preceding the date of such notice), or such lesser amount if it
constitutes the remaining holdings of the Holder and its Affiliates, or, (B) to such Holders if the Partnership has been advised by the Managing Underwriter that the inclusion of Common Unit Registrable Securities for sale for the benefit of
such Holders will have an adverse effect on the price, timing or distribution of the Common Units in such Underwritten Offering, in which case the amount of Common Unit Registrable Securities to be offered for the accounts of Holders shall be
determined based on the provisions of Section 2.02(b). Each Piggyback Notice shall be provided to Holders on a Business Day pursuant to Section 3.01 and receipt of such notice shall be confirmed and kept confidential by the
Holders until either (x) such proposed Underwritten Offering has been publicly announced by the Partnership or (y) the Holders have received notice from the Partnership that such proposed Underwritten Offering has been abandoned, which the
Partnership shall provide to the Holders reasonably promptly after the final decision to abandon a proposed Underwritten Offering has been made. Each such Holder will have four Business Days (or two Business Days in connection with any overnight or
bought Underwritten Offering) after such Piggyback Notice has been delivered to request in writing to the Partnership the inclusion of Common Unit Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is
received by the Partnership within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of the Partnership’s intention to undertake an Underwritten
Offering and prior to the pricing of such Underwritten Offering, such Underwritten Offering is terminated or delayed pursuant to the provisions of this Agreement, the Partnership may, at its election, give written notice of such determination to the
Selling Holders and, (1) in the case of a termination of such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (2) in the
case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw
such Selling Holder’s request for inclusion of such Selling Holder’s Common Unit Registrable Securities in such Underwritten Offering by giving written notice to the Partnership of such withdrawal at least one Business Day prior to the
time of pricing of such Underwritten Offering. Any Holder may deliver written notice (a “Piggyback  

  
 9 








 
Opt-Out Notice”) to the Partnership requesting that such Holder not receive notice from the Partnership of any proposed Underwritten Offering; provided, however,
that such Holder may later revoke any such Piggyback Opt-Out Notice in writing. Following receipt of a Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), the Partnership shall not be required to deliver any notice to such Holder
pursuant to this Section 2.02(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings pursuant to this Section 2.02(a), unless such Piggyback Opt-Out Notice is revoked by such Holder. The
Holders listed on Schedule B shall each be deemed to have delivered a Piggyback Opt-Out Notice as of the date hereof. 
 (b)
Priority of Piggyback Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering for Other Holders advise the Partnership that the total amount of Common Unit Registrable Securities that Holders
intend to include in such offering exceeds the number that can be sold in such 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
Partnership shall include the number of Common Units that such Managing Underwriter or Underwriters advise the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Common Units requested
to be included therein by the Initiating Holder and (ii) second, pro rata among the Holders who are exercising piggyback registration rights pursuant to this Section 2.02 related to such offering (based, for each such Holder, on the
percentage derived by dividing (x) the number of Common Units proposed to be sold by such Holder in such Underwritten Offering by (y) the aggregate number of Common Units proposed to be sold by all Holders in such Underwritten Offering).

 Section 2.03 Underwritten Offering. 

(a) Purchaser Demand Rights. If Stonepeak, First Reserve or any of their respective Affiliates elect to dispose of Common
Unit Registrable Securities under a Registration Statement pursuant to an Underwritten Offering and either (i) reasonably expect gross proceeds of at least $100 million from such Underwritten Offering (together with any Common Unit Registrable
Securities to be disposed of by a Selling Holder who has elected to participate in such Underwritten Offering pursuant to Section 2.02) or (ii) reasonably expect gross proceeds of at least $50 million from such Underwritten Offering
(together with any Common Unit Registrable Securities to be disposed of by a Selling Holder who has elected to participate in such Underwritten Offering pursuant to Section 2.02) and such Common Unit Registrable Securities represent 100%
of the then-outstanding Common Unit Registrable Securities held by the applicable Selling Holder and its affiliates, the Partnership shall, at the written request of such Selling Holder(s), enter into an underwriting agreement in a form as is
customary in Underwritten Offerings of securities by the Partnership with the Managing Underwriter or Underwriters selected by the Partnership, which shall include, among other provisions, indemnities to the effect and to the extent provided in
Section 2.08, and shall take all such other reasonable actions as are requested by the Managing Underwriter or Underwriters in order to expedite or facilitate the disposition of such Common Unit Registrable Securities; provided,
however, that the Partnership shall have no obligation to facilitate or participate in, including entering into any underwriting agreement for more than (i) two Underwritten Offerings requested by Stonepeak or any of or its Affiliates
(which shall never occur within 365 days of each other) and (ii) one Underwritten Offering requested by First Reserve or any of its Affiliates (which 

  
 10 








 
shall never occur within 365 days of any other Underwritten Offering requested hereunder); provided, further, that if the Partnership, DRI or any of their respective Affiliates is
conducting or actively pursuing a securities offering of the Partnership’s Common Units with anticipated gross offering proceeds of at least $100 million (other than in connection with any at-the-market offering or similar continuous offering
program), then the Partnership may suspend such Selling Holder’s right to require the Partnership to conduct an Underwritten Offering on such Selling Holder’s behalf pursuant to this Section 2.03; provided,
however, that the Partnership may only suspend such Selling Holder’s right to require the Partnership to conduct an Underwritten Offering pursuant to this Section 2.03 once in any six-month period and in no event for a period
that exceeds an aggregate of 60 days in any 180-day period or 90 days in any 365-day period. 
 (b) General Procedures. In
connection with any Underwritten Offering contemplated by Section 2.02 or Section 2.03(a), the underwriting agreement into which each Selling Holder and the Partnership shall enter shall contain such representations,
covenants, indemnities (subject to Section 2.08) and other rights and obligations as are customary in Underwritten Offerings of securities by the Partnership. No Selling Holder shall be required to make any representations or warranties
to or agreements with the Partnership or the Underwriters other than representations, warranties or agreements regarding such Selling Holder’s authority to enter into such underwriting agreement and to sell, and its ownership of, the securities
being registered on its behalf, its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an Underwritten Offering contemplated by this Section 2.03, such Selling
Holder may elect to withdraw therefrom by notice to the Partnership and the Managing Underwriter; provided, however, that such withdrawal must be made at least one Business Day prior to the time of pricing of such Underwritten Offering
to be effective; provided, further, that in the event the Managing Underwriter or Underwriters of any proposed Underwritten Offering advise the Partnership that the total amount of Common Unit Registrable Securities that Holders intend
to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Unit Registrable Securities offered or the market for the Common
Units, and the amount of Common Unit Registrable Securities requested to be included in such Underwritten Offering by the Holder that initiated such Underwritten Offering pursuant to Section 2.03(a) (the “Initiating
Holder”) is reduced by 50% or more, the Initiating Holder will have the right to withdraw from such Underwritten Offering by delivering notice to the Partnership at least one Business Day prior to the time of pricing of such
Underwritten Offering, in which case the Partnership will have no obligation to proceed with such Underwritten Offering and such Underwritten Offering, whether or not completed, will not decrease the number of Underwritten Offerings the Initiating
Holder shall have the right and option to request under this Section 2.03. No such withdrawal or abandonment shall affect the Partnership’s obligation to pay Registration Expenses. 

Section 2.04 Further Obligations. In connection with its obligations under this Article II, the Partnership
will: 
 (a) promptly prepare and file with the Commission such amendments and supplements to a Registration Statement and the prospectus
used in connection therewith as may be necessary to keep such 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
Registrable Securities covered by such Registration Statement; 

  
 11 








 (b) if a prospectus supplement will be used in connection with the marketing of an Underwritten
Offering under a Registration Statement and the Managing Underwriter at any time shall notify the Partnership in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus
supplement is of material importance to the success of such Underwritten Offering, the Partnership shall use its commercially reasonable efforts to include such information in such prospectus supplement; 

(c) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing a Registration Statement or any other
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 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, to the extent timely received, make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such Registration Statement or such other registration statement and the
prospectus included therein or any supplement or amendment thereto, and (ii) such number of copies of such Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments
thereto as such Persons may reasonably request in order to facilitate the resale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement; 

(d) if applicable, use its commercially reasonable efforts to promptly register or qualify the Registrable Securities covered by any
Registration Statement or any other 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, however, that the Partnership 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 that would subject it to
general service of process in any such jurisdiction where it is not then so subject; 
 (e) promptly notify each Selling Holder, at any time
when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of a Registration Statement or any other 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 a Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become
effective; and (ii) the receipt of 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 such Registration Statement or
any other registration statement or any prospectus or prospectus supplement thereto; 

  
 12 








 (f) promptly notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered by any of them under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in a Registration Statement or any other 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 case of any
prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement or
any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Partnership 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, the Partnership agrees to, as promptly as 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 reasonably necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(g) upon request and subject to appropriate confidentiality obligations, 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; 
 (h) in the case of an Underwritten Offering, furnish, or use its reasonable efforts to cause to be furnished, upon request,
(i) an opinion of counsel for the Partnership addressed to the Underwriters, dated the date of the closing under the applicable underwriting agreement and (ii) a “comfort letter” addressed to the Underwriters, dated the pricing
date of such Underwritten Offering and a letter of like kind dated the date of the closing under the applicable underwriting agreement, in each case, signed by the independent public accountants who have certified the Partnership’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) as have been customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the Underwriters in Underwritten Offerings of securities by
the Partnership and such other matters as such Underwriters may reasonably request; 
 (i) otherwise use its commercially reasonable efforts
to comply with all applicable rules and regulations of the Commission; 
 (j) make available to the appropriate representatives of the
Managing Underwriter during normal business hours access to such information and Partnership personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided,
however, that the Partnership need not disclose any non-public information to any such representative unless and until such representative has entered into a confidentiality agreement with the Partnership; 

  
 13 








 (k) use its commercially reasonable efforts to cause all Common Unit 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 the Partnership are then listed; 

(l) use its commercially reasonable efforts to cause 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 the Partnership to enable the Selling Holders to consummate the disposition of such Registrable Securities; 

(m) provide a transfer agent, which may be the General Partner or one of its Affiliates as provided in the Partnership Agreement, and
registrar for all Registrable Securities covered by any Registration Statement not later than the Effective Date of such Registration Statement; 

(n) 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 Common Unit Registrable Securities (including making appropriate officers of the General Partner available to participate in customary marketing activities); provided, however,
that the officers of the General Partner shall not be required to dedicate an unreasonably burdensome amount of time in connection with any roadshow and related marketing activities for any Underwritten Offering; 

(o) if reasonably requested by a Selling Holder, (i) incorporate in a prospectus supplement or post-effective amendment such information
as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price
being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters
to be incorporated in such prospectus supplement or post-effective amendment; 
 (p) if reasonably required by the Partnership’s
transfer agent, the Partnership shall promptly deliver any authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to transfer Registrable Securities without legend upon sale by the
Holder of such Registrable Securities under a Registration Statement; and 
 (q) if any Holder could reasonably be deemed to be an
“underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with a Registration Statement and any amendment or supplement thereof (a “Holder Underwriter Registration Statement”), then the
Partnership will reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s due diligence” with respect to the Partnership and satisfy its obligations in respect thereof. In addition, at any
Holder’s request, the Partnership will furnish to 

  
 14 








 
such Holder, on the date of the effectiveness of the Holder Underwriter Registration Statement and thereafter from time to time on such dates as such Holder may reasonably request (provided that
such request shall not be more frequently than on an annual basis unless such Holder is offering Registrable Securities pursuant to a Holder Underwriter Registration Statement), (i) a “comfort letter”, dated such date, from the
Partnership’s independent certified public accountants in form and substance as has been customarily given by independent certified public accountants to underwriters in Underwritten Offerings of securities by the Partnership, addressed to such
Holder, (ii) an opinion, dated as of such date, of counsel representing the Partnership for purposes of the Holder Underwriter Registration Statement, in form, scope and substance as has been customarily given in Underwritten Offerings of
securities by the Partnership, accompanied by standard “10b-5” negative assurance for such offerings, addressed to such Holder and (iii) a standard officer’s certificate from the chief executive officer or chief financial
officer, or other officers serving such functions, of the General Partner addressed to the Holder, as has been customarily given by such officers in Underwritten Offerings of securities by the Partnership. The Partnership will also use its
reasonable efforts to provide legal counsel to such Holder with an opportunity to review and comment upon any such Holder Underwriter Registration Statement, and any amendments and supplements thereto, prior to its filing with the Commission. 

Notwithstanding anything to the contrary in this Section 2.04, the Partnership will not name a Holder as an underwriter (as
defined in Section 2(a)(11) of the Securities Act) in any Registration Statement or Holder Underwriter Registration Statement, as applicable, without such Holder’s consent. If the staff of the Commission requires the Partnership to name
any Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act), and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the applicable Registration Statement, and
the Partnership shall have no further obligations hereunder with respect to Registrable Securities held by such Holder, unless such Holder has not had an opportunity to conduct customary underwriter’s due diligence as set forth in subsection
(q) of this Section 2.04 with respect to the Partnership at the time such Holder’s consent is sought. 
 Each
Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in subsection (f) of this Section 2.04, shall forthwith discontinue offers and sales of the Registrable
Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (f) of this Section 2.04 or until it is
advised in writing by the Partnership 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 the Partnership, such Selling
Holder will, or will request the Managing Underwriter or Managing Underwriters, if any, to deliver to the Partnership (at the Partnership’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. 

Section 2.05 Cooperation by Holders. The Partnership shall have no obligation to include Registrable Securities of a Holder
in a Registration Statement or in an Underwritten Offering pursuant to Section 2.03(a) if such Holder has failed to timely furnish such information 

  
 15 








 
that the Partnership determines, after consultation with its counsel, is reasonably required in order for any registration statement or prospectus supplement, as applicable, to comply with the
Securities Act. 
 Section 2.06 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Common
Unit Registrable Securities who is participating in an Underwritten Offering and is included in a Registration Statement agrees to enter into a customary letter agreement with underwriters providing that such Holder will not effect any public sale
or distribution of Common Unit Registrable Securities during the 45 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of such Underwritten Offering;
provided, however, that, notwithstanding the foregoing, (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction imposed by the Underwriters on the Partnership or the
officers, directors or any other Affiliate of the Partnership on whom a restriction is imposed and (ii) the restrictions set forth in this Section 2.06 shall not apply to any Common Unit Registrable Securities that are included in
such Underwritten Offering by such Holder. 
 Section 2.07 Expenses. 

(a) Certain Definitions. “Registration Expenses” shall not include Selling Expenses but otherwise means
all expenses incident to the Partnership’s performance under or compliance with this Agreement to effect the Registration of Registrable Securities on a Registration Statement pursuant to Section 2.01, a Piggyback Registration
pursuant to Section 2.02, or an Underwritten Offering pursuant to Section 2.03, and the disposition of such Registrable Securities, including all registration, filing, securities exchange listing and National Securities
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, fees of transfer agents and registrars, all word processing,
duplicating and printing expenses, and the fees and disbursements of counsel and independent public accountants for the Partnership, including the expenses of any special audits or “cold comfort” letters required by or incident to such
performance and compliance. “Selling Expenses” means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the Registrable Securities, plus any costs or expenses related to any
roadshows conducted in connection with the marketing of any Underwritten Offering. 
 (b) Expenses. The Partnership will pay
all reasonable Registration Expenses, as determined in good faith, in connection with a shelf Registration, a Piggyback Registration or an Underwritten Offering, whether or not any sale is made pursuant to such shelf Registration, Piggyback
Registration or Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition, except as otherwise provided in
Section 2.08, the Partnership shall not be responsible for professional fees (including legal fees) incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

 Section 2.08 Indemnification. 

(a) By the Partnership. In the event of a Registration of any Registrable Securities under the Securities Act pursuant to this
Agreement, the Partnership will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, partners, employees and agents and each Person, if any, who controls such Selling Holder within the meaning of the
Securities Act and the Exchange Act, and its directors, officers, managers, partners, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or
liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified 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 (in the case of any prospectus,
in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the applicable Registration Statement or other registration statement contemplated by
this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto, 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 Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending or resolving any such Loss or actions or proceedings; provided, however, that the Partnership
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 such
Selling Holder Indemnified Person in writing specifically for use in the applicable Registration Statement or other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of such Selling Holder Indemnified 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 the Partnership,
the General Partner and the General Partner’s directors, officers, employees and agents and each Person, who, directly or indirectly, controls the Partnership within the meaning of the Securities Act or of the Exchange Act to the same extent as
the foregoing indemnity from the Partnership 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 a Registration Statement
or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereto or any free writing prospectus relating thereto;
provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities
giving rise to such indemnification. 

  
 17 








 (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 to so notify the indemnifying
party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.08(c), except to the extent that the indemnifying party is materially prejudiced by such failure. 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 2.08 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 or employ counsel reasonably satisfactory to the indemnified party 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 any indemnified party with respect to which such indemnified party may be entitled to indemnification hereunder without the consent
of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete and unconditional release from liability of, and does not contain any admission of wrongdoing by, the indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency
of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless 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 in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with
the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall any Selling Holder be required to contribute an aggregate amount in excess of
the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party, on the one hand, and the indemnified
party, 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 

  
 18 








 
paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. 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, defending or
resolving any Loss that 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 2.08 shall be in
addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.09 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the resale of the Registrable Securities without registration, the Partnership agrees to use its commercially reasonable efforts to: 

(a) make and keep public information regarding the Partnership available, as those terms are understood and defined in Rule 144 under the
Securities Act (or any similar provision then in effect), 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 the Partnership 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 (i) to the extent accurate, forthwith upon request, a written statement
of the Partnership that it has complied with the reporting requirements of Rule 144 under the Securities Act (or any similar provision then in effect) and (ii) unless otherwise available via the Commission’s EDGAR filing system, to such
Holder forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, 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 2.10 Transfer or Assignment of
Registration Rights. The rights to cause the Partnership to register Registrable Securities under this Article II may be transferred or assigned by each Holder to one or more transferees or assignees of Registrable Securities;
provided, however, that (a) unless any such transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Holder, the amount of Registrable Securities transferred or
assigned to such transferee or assignee shall represent at least $50 million of Registrable Securities (on an as-converted basis where applicable (determined by multiplying the number of Registrable Securities (on an as-converted basis) owned by the
Average VWAP for the 10 Trading Days preceding the date of such transfer or assignment)), or such lesser amount if it constitutes the remaining holdings of the Holder and its Affiliates, (b) the Partnership is given written notice prior to any
said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned and (c) each such transferee or
assignee assumes in writing responsibility for its portion of the obligations of such transferring Holder under this Agreement. 

  
 19 








 Section 2.11 Limitation on Subsequent Registration Rights. From and after the
date hereof, the Partnership shall not, without the prior written consent of the Holders of at least the Registrable Securities Required Voting Percentage, enter into any agreement with any current or future holder of any securities of the
Partnership that would allow such current or future holder to require the Partnership to include securities in any registration statement filed by the Partnership for Other Holders on a basis other than pari passu with, or expressly
subordinate to, the piggyback rights of the Holders of Common Unit Registrable Securities hereunder; provided, that in no event shall the Partnership enter into any agreement that would permit another holder of securities of the Partnership
to participate on a pari passu basis (in terms of priority of cut-back based on advice of underwriters) with a Purchaser requesting registration or takedown in an Underwritten Offering pursuant to Section 2.03(a). 

Section 2.12 Limitation on Obligations for Series A Preferred Unit Registrable Securities. Notwithstanding anything to the
contrary in this Agreement, nothing contained herein shall be construed to require the Partnership to (a) conduct an underwritten offering for the public sale, resale or any other disposition of Series A Preferred Unit Registrable Securities,
(b) except as expressly provided in this Agreement, otherwise assist in the public resale of any Series A Preferred Unit Registrable Securities, (c) provide any Holder of Series A Preferred Unit Registrable Securities any rights to include
any Series A Preferred Unit Registrable Securities in any underwritten offering relating to the sale by the Partnership or any other Person of any securities of the Partnership or (d) cause any Series A Preferred Unit Registrable Securities to
be listed on any securities exchange or nationally recognized quotation system.

Section 3.02 Binding Effect. This Agreement shall be binding upon the Partnership, each of the Purchasers and their
respective successors and permitted assigns, including subsequent Holders of Registrable Securities to the extent permitted herein. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or
benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns. 

Section 3.03 Assignment of Rights. Except as provided in Section 2.10, neither this Agreement nor any of the
rights, benefits or obligations hereunder may be assigned or transferred, by operation of law or otherwise, by any party hereto without the prior written consent of the other party.

extent set forth herein with respect to any and all units of the Partnership or any successor or assign of the Partnership (whether by merger, acquisition, consolidation, reorganization, sale of assets or otherwise) that may be issued in respect of,

Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. 

Section 3.06 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if

jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the 

  
 21 








 
ground of lack of 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 Person from pursuing any
other rights and remedies at law or in equity that such Person may have. 
 Section 3.07 Counterparts. This Agreement may
be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall
constitute but one and the same agreement.

all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising
out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the State of Delaware without regard to principles of conflicts of laws. Any action
against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any
federal or state court located within the State of Delaware over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue of
any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. 
 Section 3.09 Waiver of Jury Trial. THE PARTIES TO THIS AGREEMENT EACH HEREBY
WAIVE, AND AGREE TO CAUSE THEIR AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR (B) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. THE
PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

Section 3.10 Entire Agreement . This Agreement, the Purchase Agreement and the other agreements and documents referred to
herein and therein are 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
and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or in the Purchase Agreement with respect to the rights 

  
 22 








 
granted by the Partnership or any of its Affiliates or the Purchasers or any of their respective Affiliates set forth herein or therein. This Agreement, the Purchase Agreement and the other
agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter. 

Section 3.11 Amendment. This Agreement may be amended only by means of a written amendment signed by the Partnership and
the Holders of at least the Registrable Securities Required Voting Percentage; provided, however, that no such amendment shall adversely affect the rights of any Holder hereunder without the consent of such Holder. Any amendment,
supplement or modification of or to any provision of this Agreement, any waiver of any provision of this Agreement, and any consent to any departure by the Partnership or any Holder from the terms of any provision of this Agreement shall be
effective only in the specific instance and for the specific purpose for which such amendment, supplement, modification, waiver or consent has been made or given. 

Section 3.12 No Presumption. This Agreement has been reviewed and negotiated by sophisticated parties with access to legal
counsel and shall not be construed against the drafter. 
 Section 3.13 Obligations Limited to Parties to Agreement. Each
of the parties hereto covenants, agrees and acknowledges that, other than as set forth herein, no Person other than the Purchasers, the Holders, their respective permitted assignees and the Partnership shall have any obligation hereunder and that,
notwithstanding that one or more of such Persons may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith shall be had against any former,
current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of such Persons or their respective permitted assignees, or any former, current or future director, officer, employee,
agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed
and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate
of any of such Persons or any of their respective assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any
obligations of such Persons or their respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or for any claim based on, in respect of or by reason of such obligation or its creation,
except, in each case, for any assignee of any Purchaser or a Selling Holder hereunder. 
 Section 3.14 Interpretation.
Article, Section and Schedule references in this Agreement are references to the corresponding Article, Section or Schedule to this Agreement, unless otherwise specified. All Schedules to this Agreement are hereby incorporated and made a part hereof
as if set forth in full herein and are an integral part of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended,
supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it 

  
 23 








 
follows to the specific or similar items or matters immediately following it. Whenever the Partnership has an obligation under this Agreement, the expense of complying with that obligation shall
be an expense of the Partnership unless otherwise specified. Any reference in this Agreement to “$” shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by a Purchaser, such action shall be in
such Holder’s sole discretion, unless otherwise specified in this Agreement. If any provision in this Agreement is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and this Agreement
shall be construed and enforced as if such illegal, invalid, not binding or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect, and (b) the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to
the greatest extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be
excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. The words such as “herein,” “hereinafter,” “hereof’ and “hereunder” refer
to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and
the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement.

 Exhibit D 

FORM OF GENERAL PARTNER WAIVER 

[●], 2016 
 Reference is
hereby made to that certain Series A Preferred Unit and Common Unit Purchase Agreement, dated as of [●], 2016, by and among Dominion Midstream Partners, LP (the “Partnership”) and each of the Purchasers set forth in Schedule A
thereto (the “Purchase Agreement”), pursuant to which the Partnership has agreed to issue and sell (a) an aggregate of [●] Series A Preferred Units representing limited partner interests of the Partnership, for a cash purchase

periodic basis, such as the deduction for depreciation, shall be apportioned to the period prior to and including the Closing Date ratably on a per diem basis).

recover from Contributor the amount of Taxes attributable to the portion of the taxable period ending on or prior to the Closing Date pursuant to Section 5.2(b). 

(e) Notwithstanding the foregoing, to the extent that transfer taxes arise from the transactions contemplated by this

collect and remit. Acquirer shall indemnify and hold Contributor harmless from and against its share of any such transfer taxes within thirty (30) days of Contributor’s written demand therefor. The Parties shall provide such certificates
and other information and otherwise cooperate to the extent reasonably required to minimize transfer taxes.

 (f) Each Party shall file, to the extent required by applicable Tax Laws, all
necessary Tax Returns and other documentation with respect to all Taxes for which such Party is responsible hereunder. In addition, each Party shall provide the other Parties with such assistance as may be reasonably requested by such other Parties
or otherwise required by applicable Tax Laws in connection with the preparation, execution and/or filing of any Tax Return and other related documentation, any audit or other examination by any Governmental Authority, or any judicial or
administrative proceedings relating to liability for Taxes, and each will retain and provide the requesting Party or Parties with any records or information which may be relevant to such return, audit or examination, proceedings or determination.

 (g) The parties intend that for United States federal income tax purposes, (i) the contribution of the Interests
shall be treated as a contribution by Contributor to Acquirer pursuant to Section 721(a) of the Code, subject to Section 707 of the Code, and (ii) the distribution of the Debt Financed Cash Consideration shall qualify as a “debt-
financed transfer” under Section 1.707-5(b) of the Treasury Regulations pursuant to Section 5.3 of this Agreement. Any Cash Consideration in excess of the amount treated as a “debt-financed transfer” shall be treated
(x) as a reimbursement of Contributor’s preformation expenditures within the meaning of Section 1.707-4(d) of the Treasury Regulations to the greatest extent applicable, and (y) in a transaction subject to treatment under
Section 707(a) of the Code, and its implementing Treasury Regulations, as in part a sale, and in part a contribution, by Contributor of the Interests. The Parties agree to file all Tax Returns and otherwise act at all times in a manner
consistent with this intended treatment of the contribution of the Interests, the Cash Consideration, and the Acquirer Debt, including disclosing the payment of the Cash Consideration in accordance with the requirements of Section 1.707-3(c)(2)
of the Treasury Regulations. 
 Section 5.3 Debt Financed Cash Consideration 

(a) Prior to or simultaneous with the Closing and pursuant to the Term Loan Agreement, Acquirer shall use its best efforts to
borrow at least $300 million of the Cash Consideration (the “Debt Financed Cash Consideration”) under indebtedness for which Contributor bears all of the economic risk of loss as defined by Treasury Regulation
Section 1.752-2, in a manner such that the proceeds of such borrowing are allocable to the distribution of the Debt Financed Cash Consideration to Contributor pursuant to Treasury Regulation Section 1.707-5(b)(1) and Temporary Treasury
Regulation 1.163-8T (the full amount of such borrowing, and any “refinancing” of such borrowing treated as the liability it refinances pursuant to Treasury Regulation Section 1.707-5(c), the “Acquirer Debt”).

 (b) The Parties intend that, because Contributor will bear the economic risk of loss as defined by Treasury Regulation
Section 1.752-2 for the entire amount of the Acquirer Debt, the entire amount of the Debt Financed Cash Consideration made to Contributor shall qualify as a “debt-financed transfer” under Treasury Regulation Section 1.707-5(b)
and accordingly, such amount will not be taken into account as part of a “disguised sale” of property contributed to Acquirer under Treasury Regulations Section 1.707-3. 

  
 -22- 








 (c) The Parties hereby agree (and agree on behalf of their respective Affiliates)
that, as of the Closing Date, the Parties (and their respective Affiliates) have no plan to repay or otherwise reduce the principal balance of the Acquirer Debt that is outstanding immediately after the Closing Date. 

(d) The Parties shall act at all times in a manner consistent with the foregoing provisions of this Section 5.3,
except with the prior written consent of Parent or as otherwise required by applicable Law following a final determination by the U.S. Internal Revenue Service or a Governmental Authority with competent jurisdiction. 

Section 5.4 Repurchase of DM Common Units. The Parties shall use their best efforts to cause 100% of the DMHC Existing Units to be
repurchased by Acquirer on the Closing Date in exchange for a cash payment from Acquirer equal to the number of DMHC Existing Units multiplied by the volume-weighted average trading price of a DM Common Unit on the New York Stock Exchange for the
10-day trading period ending on the trading day immediately preceding the Closing Date. 
 Section 5.5 Personnel and
Services. Parent shall use its best efforts to make arrangements reasonably satisfactory to Acquirer that provide Acquirer with access to ongoing personnel and related services from QPC Services Company or other Affiliates of Parent, on terms
consistent with the projections provided to the Acquirer Conflicts Committee as part of the Acquirer Conflicts Committee’s evaluation of this Agreement and the transactions contemplated hereby, that are reasonably necessary or appropriate to
replace the services being performed by the employees of the Company and each Company Subsidiary as of the Effective Date. 

Section 5.6 Further Assurances; Financing Cooperation. 

(a) At any time or from time to time after the Effective Date and without further consideration, as and when requested by any
Party, the requested Party shall use commercially reasonable efforts to take or to cause to be taken, all action and to do, or cause to be done, or to execute and deliver, or cause to be executed and delivered, all such further instruments of
contribution, transfer, conveyance, assignment, novation, confirmation or other documents, and shall take, or cause to be taken, all such further or other actions, as such requesting Party may reasonably deem necessary, proper or advisable to
consummate the Contemplated Transactions, as promptly as practicable or sooner as required by this Agreement. 
 (b)
Contributor shall, and shall cause the Company and each Company Subsidiary to, provide commercially reasonable assistance with the preparation of and any discussions regarding the business, financial statements, and management discussion and
analysis of Contributor, the Company and each Company Subsidiary, all for use in connection with the Transaction Financings, where Acquirer reasonably determines, in consultation with Parent, that the inclusion of such information is required or
desirable.

consultants, agents and representatives (the “Acquirer Indemnified Parties”), from any and all Adverse Consequences actually incurred or paid by an Acquirer Indemnified Party as a result of (i) any breach of the

RESULTING FROM, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (a) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT

PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.

joint venture or other entity or similar legal relationship among the Parties, or impose a trust, partnership or fiduciary duty, obligation, or liability on or with respect to the Parties. Except as expressly provided herein, no Party is or shall
act as or be the agent or representative of any other Party. 
 Section 9.12 Severability. If any term or other provision of
this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the
Contemplated Transactions is not affected in any manner adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the Parties as closely as possible in order that the Contemplated Transactions be consummated as originally contemplated to the greatest extent possible.
