(d) by the Contributor Parties, if there shall have been a breach of any representation, warranty, covenant or agreement on the part of any Acquirer Party contained in this Agreement such that the conditions set forth in Section 6.4(a) or 6.4(b) would not be satisfied, and such breach is not capable of being cured or, if capable of being cured, shall not have been cured prior to the earlier of (x) the Outside Date and (y) 30 days after notice of the breach is provided to the Acquirer Parties; provided, that the Contributor Parties shall not have the right to terminate this Agreement pursuant to this Section 7.1(d) if any Contributor Party is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement;

-24-

(e) by the Acquirer Parties, if there shall have occurred after the Effective Date an Iroquois Material Adverse Effect that, with the exercise of Reasonable Efforts, cannot reasonably be expected to be cured prior to the Outside Date.

(f) by the Contributor Parties, if there shall have occurred after the Effective Date a DM Material Adverse Effect that, with the exercise of Reasonable Efforts, cannot reasonably be expected to be cured prior to the Outside Date; or

(g) by either the Contributor Parties or the Acquirer Parties, if after the Effective Date any Governmental Authority shall have issued an Order or taken any other action enjoining or otherwise prohibiting the Contemplated Transactions and such Order or other action shall have become final and nonappealable.

Section 7.2 Procedure Upon Termination and Consequences. The Acquirer Parties or the Contributor Parties may terminate this Agreement when permitted pursuant to Section 7.1 by delivering written notice of such termination to the other Parties, and such termination shall be effective upon delivery of such notice in accordance with Section 9.3. If this Agreement is terminated as provided herein, (i) this Agreement shall forthwith become void, except that Section 1.1 (Definitions), Section 5.7 (Confidentiality Agreement), this Section 7.2 (Procedure Upon Termination and Consequences), Section 8.5(f) and Article IX (Miscellaneous) shall survive such termination. Except as set forth in the following sentence, such termination shall be the sole remedy of the Parties with respect to breaches of any covenant, agreement, representation or warranty contained in this Agreement and none of the Parties, their Affiliates or any of their respective Representatives, as the case may be, shall have any liability or further obligation to any other Party except with respect to the Confidentiality Agreement, which shall survive the termination of this Agreement in accordance with its terms, including with respect to information that is subject to the Confidentiality Agreement pursuant to this Agreement. Notwithstanding the foregoing, (x) in the event of a termination by the Acquirer Parties pursuant to Section 7.1(b) (under circumstances where the Contributor Parties would have been unable to terminate this Agreement pursuant to Section 7.1(b)) or Section 7.1(c), such termination shall not relieve any Contributor Party from liability for any breach of this Agreement or (y) by the Contributor Parties pursuant to Section 7.1(b) (under circumstances where the Acquirer Parties would have been unable to terminate this Agreement pursuant to Section 7.1(b)) or Section 7.1(d), such termination shall not relieve the Acquirer Parties from liability for any breach of this Agreement. Nothing in this Section 7.2 shall be deemed to impair the right of any Party to bring an Action for specific performance and to assert all other rights and remedies, and (subject to Section 8.5(f) hereof) recover all damages, available to it at law or in equity.

ARTICLE VIII

INDEMNIFICATION

Section 8.1 Indemnification.

(a) Indemnification by Contributor Parties. Subject to the limitations set forth in this Article VIII, from and after the Closing, each Contributor Party shall severally, but not jointly, indemnify, defend, reimburse and hold harmless each Acquirer Party, its Affiliates and each of their respective Representatives (the “Acquirer Indemnified

-25-

Parties”), from any and all Adverse Consequences actually incurred or paid by an Acquirer Indemnified Party as a result of (i) any breach of any representation or warranty of such Contributor Party contained this Agreement, (ii) any breach of any covenant or agreement of such Contributor Party contained in this Agreement, or (iii) any Transfer Taxes for which any Contributor Party is responsible pursuant to Section 5.4(d).

(b) Indemnification by Acquirer Parties. Subject to the limitations set forth in this Article VIII, from and after the Closing, the Acquirer Parties shall, jointly and severally, indemnify, defend, reimburse and hold harmless each Contributor Party, its Affiliates and each of their respective Representatives (the “Contributor Indemnified Parties”), from any and all Adverse Consequences actually incurred or paid by a Contributor Indemnified Party as a result of (i) any breach of any representation or warranty of any Acquirer Party contained in this Agreement, (ii) any breach of any covenant or agreement of any Acquirer Party contained in this Agreement, or (iii) any Transfer Taxes for which any Acquirer Party is responsible pursuant to Section 5.4(d).

Section 8.2 Procedure for Indemnification.

(a) Each claim for indemnification, including Third Party Claims, shall be made by delivery by the Person seeking to be indemnified (the “Indemnified Party”) to the Party from whom indemnification is sought (the “Indemnifying Party”) of written notice (a “Claim Notice”) containing details reasonably sufficient to disclose to the Indemnifying Party the nature and scope of the claim including an estimate of the amount of claimed Adverse Consequences and copies of all relevant pleadings, documents and information, in each case to the extent reasonably practicable, within thirty (30) days after the Indemnified Party obtains knowledge of such claim. Any failure in the delivery of a Claim Notice shall not affect the obligations of the Indemnifying Party, except to the extent that the rights and remedies of the Indemnifying Party are actually materially prejudiced as a result of the failure to give, or delay in giving, such Claim Notice.

(b) If, pursuant to a Third Party Claim, any Action is brought against an Indemnified Party for which the Indemnifying Party may be required to indemnify the Indemnified Party hereunder, the Indemnifying Party shall be entitled to participate in the defense of such Action and, to the extent that it elects, by written notice to the Indemnified Party within ten (10) Business Days after receipt of the relevant Claim Notice, to assume and control the defense of such Action (unless (i) the Indemnified Party determines in good faith that a conflict of interest may exist such that joint representation of the Indemnified Party and the Indemnifying Party would be inappropriate, (ii) greater than 50% of the Adverse Consequences resulting from such claim are reasonably anticipated to be incurred by the Indemnified Party because such Adverse Consequences exceed the Cap (if applicable), (iii) material equitable or other non-monetary relief is sought from any Indemnified Party pursuant to such Action, or (iv) the claim is brought by a Governmental Authority). After notice from the Indemnifying Party to the Indemnified Party of its election to assume and control the defense of such Action, the Indemnifying Party shall not, so long as it diligently conducts such defense, be liable to the Indemnified Party under this Article VIII for any fees of other counsel or any other expenses with respect to the defense of such Action, in each case subsequently incurred by the

-26-

Indemnified Party in connection with the defense of such Action, other than reasonable costs of investigation. If the Indemnifying Party assumes the defense of such Action, (i) such assumption will, unless additional information emerges after the assumption to change this conclusion, conclusively establish for purposes of this Agreement that the Third Party Claims are within the scope of and subject to indemnification (but no such assumption shall affect the applicability of any limit on indemnification contained in Section 8.5), and (ii) the Indemnifying Party shall not, without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, compromise or settle such Action, or consent to the entry of any judgment with respect to such Action, that (A) does not involve only the payment of monetary damages by the Indemnifying Party and does not otherwise result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a compromise or settlement, an unconditional written release of the Indemnified Part), (B) is reasonably expected to materially and adversely affect the Indemnified Party, including the imposition of any materially adverse restriction, condition, injunction or other equitable relief upon the Indemnified Party, (C) encumbers any of the assets of the Indemnified Party, (D) involves any finding or omission of any violation of Law or admission of any wrong doing by the Indemnified Party. If the Indemnified Party withholds its consent unreasonably, the Indemnified Party shall be obligated for any future expenses and excess settlement amounts. The Indemnifying Person shall pay all amounts of such permissible compromise, settlement or judgment concurrently with the effectiveness thereof and otherwise remain responsible for any Adverse Consequences the Indemnified Party may suffer that are caused by, relating to, or arising out of the Third Person Claim to the fullest extent provided in this Article VIII. If a Claim Notice regarding a Third Party Claim is given to an Indemnifying Party and the Indemnifying Party does not, within ten (10) Business Days after the Indemnifying Party’s receipt of such Claim Notice, give notice to the Indemnified Party of its election to assume the defense of such Action, the Indemnifying Party will be deemed bound by any determination made in such Action or any compromise or settlement effected by the Indemnified Party. The Indemnified Party shall fully cooperate at its expense in connection with the defense of any such Third Party Claims, including providing reasonable access to the Indemnified Party’s records and personnel relating to such claim, and will have the right to participate in the defense of any Third Party Claim by counsel of its own choosing and at its own expense.

(c) Notwithstanding the provisions of Section 8.2(b), if the Indemnifying Party does not, or is not permitted under the terms hereof to, assume or retain control of the defense of an Action relating to a Third Party Claim, then the Indemnified Person (i) shall have the right to defend against the Third Person Claim (at the sole cost and expense of the Indemnifying Person (but subject to the limitations set forth in this Article VIII)), with counsel of the Indemnified Person’s choosing; and (ii) shall have full control of such defense and Action, including (subject to the following provisions of this Section 8.2(c)) any compromise or settlement thereof, and need not otherwise consult with the Indemnifying Person in connection therewith. If the Indemnified Person has assumed the defense pursuant to this Section 8.2(c), it shall not, without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, conditioned or delayed, compromise or settle any Third Person Claim or consent to the entry of any judgment with respect thereto.

-27-

Section 8.3 Survival. The representations and warranties of the Parties contained in this Agreement shall survive the Closing for a period of eighteen (18) months after the Closing Date; provided, however, that the Fundamental Representations shall survive indefinitely. The covenants and agreements of the Parties set forth in this Agreement shall survive the Closing indefinitely or for a period of thirty (30) days after the period explicitly specified therein.

Section 8.4 Exclusivity. Following the Closing, except for fraud, willful misrepresentation or intentional misconduct, the rights and remedies of the Contributor Indemnified Parties, on the one hand, and the Acquirer Indemnified Parties, on the other hand, for monetary damages under this Article VIII are, solely as between the Contributor Indemnified Parties on the one hand, and the Acquirer Indemnified Parties on the other hand, exclusive and in lieu of any and all other rights and remedies for monetary damages which the Contributor Indemnified Parties on the one hand, and the Acquirer Indemnified Parties on the other hand, may have under this Agreement or under applicable Laws with respect to any indemnifiable claim, whether at common law or in equity, and each Party agrees to waive any and all claims with respect thereto unless specifically provided for in this Section 8.4. Notwithstanding the foregoing, a Party may bring an Action to enforce this Article VIII.

Section 8.5 Limitation of Claims; Mitigation. Notwithstanding anything to the contrary contained herein:

(a) The maximum aggregate liability of the Contributor Parties under this Agreement (except in the case of fraud, intentional misrepresentation or willful misconduct) shall not exceed an amount equal to the Consideration Value (the “Cap”).

(b) For all purposes of the indemnity obligations of the Parties set forth in this Article VIII, with respect to any representation or warranty herein, any express qualifications or limitations set forth in such representation or warranty as to materiality, “Acquirer Material Adverse Effect” or “Contributor Material Adverse Effect” (or other similar materiality qualifier) contained therein shall be disregarded for the purposes of determining the amount of any Adverse Consequences resulting from any breach of any such representation or warranty.

(c) The maximum aggregate liability of the Acquirer Parties under this Agreement (except in the case of fraud, intentional misrepresentation or willful misconduct) shall not exceed the Cap.

(d) Each Party shall (and shall, to the extent it has authority and is permitted to do so, cause each other Acquirer Indemnified Party to, with respect to the Acquirer Parties, and each other Contributor Indemnified Party to, with respect to the Contributor Parties) use Reasonable Efforts to mitigate all Adverse Consequences after becoming aware of any event which could reasonably be expected to give rise to any Adverse Consequences that are indemnifiable hereunder, including, as applicable, pursuing any counterclaim, offset, insurance settlement or other claim which could result in a recovery that would reduce such Person’s Adverse Consequences for purposes of this Agreement.

-28-

(e) An Indemnifying Party’s indemnification obligations under this Article VIII shall be reduced (but not below zero): (i) to the extent that any Adverse Consequences related to a claim are covered by, and have been actually paid to, the Indemnified Party pursuant to, (A) a reimbursement, indemnification or payment from a third Person with respect to such Adverse Consequences, or (B) insurance policies that provide coverage with respect to such Adverse Consequences; and (ii) to take into account any Tax benefit (whether by refund, credit against or reduction in Taxes otherwise payable) arising from the incurrence of the Adverse Consequences and actually realized by the Indemnified Party or any of its Affiliates during, or before, the calendar year in which the Indemnifying Party makes a payment pursuant to this Article VIII.

(f) NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, UNDER NO CIRCUMSTANCES SHALL ANY PARTY, OR ITS AFFILIATES, OR ITS OR THEIR RESPECTIVE REPRESENTATIVES, BE RESPONSIBLE OR LIABLE FOR, AND NO PARTY SHALL BE ENTITLED TO SEEK, ANY PUNITIVE, EXEMPLARY, SPECULATIVE, SPECIAL OR CONSEQUENTIAL DAMAGES ARISING UNDER THIS AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS, INCLUDING LOST PROFITS (BUT ONLY TO THE EXTENT SUCH LOST PROFITS ARE CONSEQUENTIAL DAMAGES), UNLESS ANY SUCH AMOUNTS ARE ACTUALLY PAID TO ANY THIRD PERSON PURSUANT TO A THIRD PARTY CLAIM.

ARTICLE IX

Any failure of any Party to comply with any obligation, covenant, agreement or condition contained herein may be expressly waived in writing by the Contributor Parties, in the event of any such failure by any Acquirer Party, or by the Acquirer Parties, in the event of any such failure by any Contributor Party, but such waiver or failure to insist upon strict compliance shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, by operation of law or otherwise, by any of the Parties hereto without the prior written consent of the other Parties; provided, however, that, DM Sub may, without the prior written consent of the other Parties, assign all or any part of this Agreement, and/or assign or delegate any of its rights, interests or obligations hereunder, to one or more of its Affiliates, and if assigned or delegated at or prior to the Closing, any such Affiliate acquiring the Contributor Party Interests must be a wholly-owned (directly or indirectly) subsidiary of DM.

Section 9.5 Entire Agreement. This Agreement, the Schedules, the Exhibits, and the other Transaction Documents embody the entire agreement and understanding of the Parties hereto in respect of the subject matter contained herein, and supersedes all prior agreements and understandings among the Parties with respect to such subject matter (including that certain Letter of Intent, dated February 12, 2015, between Dominion Resources, Inc. and National Grid USA).

Section 9.6 Expenses. Except as otherwise expressly provided in this Agreement (including Section 5.4(d)), each Party shall pay its own expenses in connection with the negotiation of this Agreement, the performance of its obligations hereunder, and the consummation of the Contemplated Transactions, including, the cost of legal, technical and financial consultants.

Section 9.8 No Third Party Beneficiaries. Except as set forth in Article VIII above, this Agreement is solely for the benefit of the Parties and their respective successors and permitted assigns, and this Agreement shall not otherwise be deemed to confer upon or give to any other Person any right, claim, cause of action, or other interest herein.

Section 9.9 Governing Law; Jurisdiction. This Agreement shall be governed by and construed under the Laws of the State of New York without giving effect to any choice of law or conflict of law provision rule (whether of the State of New York or any other jurisdiction) that would require the application of any other Law. Each Party consents to personal jurisdiction in any Action brought in any court, federal or state, within the State of New York having subject matter jurisdiction arising under this Agreement, and each of the Parties hereto agrees that any Action instituted by either of them against the other with respect to this Agreement will be instituted exclusively in a court, federal or state, within the State of New York.

Section 9.11 No Duties. Nothing in this Agreement creates or is intended to impose a fiduciary duty, obligation, or liability on or with respect to the Parties.

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.

Section 9.13 Headings; References; Interpretation. All Article and Section headings in this Agreement are for convenience only and shall not be deemed to control or affect the meaning or construction of any of the provisions hereof.

Section 9.14 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall be deemed to be one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

ARTICLE II

REGISTRATION RIGHTS

Section 2.01. Shelf Registration. Subject to Section 2.03, the Partnership shall, in no event later than the 15^th Business Day following November 1, 2015, use its commercially reasonable efforts to file with the SEC a registration statement (a “Registration Statement”) on Form S-3 for an offering to be made on a continuous or delayed basis pursuant to Rule 415 under the Securities Act including, if the Partnership is then eligible, as an automatic shelf registration, covering the resale of all of the Registrable Securities (the “Shelf Registration Statement”). The Shelf Registration Statement shall be in a form permitting registration of such Registrable Securities for resale or distribution by Holders in an Underwritten Offering only. The Partnership will notify the Holders when such Shelf Registration Statement has become effective. The Partnership shall not be required to maintain in effect more than one shelf registration at any one time pursuant to this Article. The Partnership shall (subject to the limitations on registration obligations of the Partnership set forth herein) use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act as promptly as practicable after the filing of the Shelf Registration Statement, or automatically if the Partnership is eligible to file an automatically effective shelf registration statement, and (subject to the limitations on registration obligations of the Partnership set forth herein) to keep the Shelf Registration Statement continuously effective under the Securities Act (including by filing a replacement Shelf Registration Statement prior to the end of the three-year period described in Rule 415(a)(5) under the Securities Act with respect to, or upon any other termination of effectiveness of, a Shelf Registration Statement filed pursuant to this Section 2.01) until the end of the Effectiveness Period).

Section 2.02. Underwritten Offerings.

(a) Request for Underwritten Offering. In the event that one or more Holders collectively elect to dispose of then-outstanding Registrable Securities representing at least 20% of the Common Units originally issued to the Contributor Parties under the Contribution Agreement (subject to adjustment pursuant to Section 3.04) under a Shelf Registration Statement referred to in Section 2.01 pursuant to an Underwritten Offering, the Partnership shall, upon written request by such Holders, retain underwriters in order to permit such Holders to effect such sale through an Underwritten Offering. The obligation of the Partnership to retain underwriters shall include entering into an underwriting agreement in customary form with the Managing Underwriter(s), which shall include customary indemnities in favor of, and taking all reasonable actions as are requested by, the Managing Underwriter(s) to expedite or facilitate the disposition of such Registrable Securities. In the event of an Underwritten Offering, the Partnership shall, upon request of the Selling Holders, cause its management to participate, subject to and in accordance with customary and reasonable processes, in a roadshow or similar marketing effort on behalf of the Selling Holders.

(b) Limitation on Underwritten Offerings. In no event shall the Partnership be required under Section 2.02(a) to participate in more than one Underwritten Offering in any twelve-month period.

(c) General Procedures. In connection with any Underwritten Offering under Section 2.02(a), the Holders of a majority of the Registrable Securities being sold in such Underwritten Offering shall be entitled, subject to the Partnership’s consent (which is not to be unreasonably withheld), to select the Managing Underwriter(s). In connection with any Underwritten Offering under this Agreement, each Selling Holder and the Partnership shall be obligated to enter into an underwriting agreement that contains such representations and warranties, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Partnership to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to such Selling Holder’s obligations. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw from the Underwritten Offering by notice to the Partnership and the Managing Underwriter(s); provided, however, that such withdrawal must be made at a time prior to the time of pricing of such Underwritten Offering. No such withdrawal shall affect the Partnership’s obligation to pay Registration Expenses.

(d) Notwithstanding the foregoing, the terms of Sections 2.02(a), (b) and (c), and the Holders’ rights provided for under such Sections shall not be applicable to a Piggyback Registration.

Section 2.03. Delay Rights. If the General Partner determines that the Partnership’s compliance with its obligations under this Article II would be materially detrimental to the Partnership and its Partners because such registration would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction involving the Partnership, (b) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (c) render the Partnership unable to comply with applicable securities laws, then the Partnership shall have the right to postpone compliance with its obligations under this Article II for a period of not more than 90 days, provided, that such right pursuant to this Section 2.03 may not be utilized more than twice in any twelve-month period.

Section 2.04. Piggyback Registration.

(a) Whenever the Partnership proposes to register the offer and sale of any Common Units under the Securities Act (other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to “employees” of the Partnership pursuant to any “employee benefit plans” (as such terms are defined for purposes of Form S-8)), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) in connection with any dividend or distribution reinvestment or similar plan or (iv) pursuant to an at-the-market equity offering program), whether for its own account or for the account of one or

more unitholders of the Partnership and the form of Registration Statement (a “Piggyback Registration Statement”) to be used may be used for registration of Registrable Securities (a “Piggyback Registration”), the Partnership shall give prompt written notice (in any event no later than ten days prior to the filing of such Registration Statement) to each Holder of its intention to effect such a registration (a “Piggyback Registration Notice”). Subject to Section 2.04(b), Section 2.04(c) and Section 2.12, the Partnership shall include in such registration all Registrable Securities with respect to which the Partnership has received written requests for inclusion from Holders of Registrable Securities within five days after the Piggyback Registration Notice has been given to each Holder. Subject to Section 2.04(b), Section 2.04(c) and Section 2.12, if any Piggyback Registration Statement that includes Registrable Securities is a Shelf Registration Statement (a “Piggyback Shelf Registration Statement”), the Holder(s) of such Registrable Securities shall be notified by the Partnership of, and shall have the right but not the obligation to participate in, any offering under such Piggyback Shelf Registration Statement (a “Piggyback Shelf Takedown”).

(b) If a Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary Underwritten Offering on behalf of the Partnership and the Managing Underwriter(s) advises the Partnership in writing that in its reasonable and good faith opinion, the inclusion of any Common Units in such registration or takedown other than Common Units being issued by the Partnership would exceed the number of Common Units that can be sold in such offering or would materially adversely affect the price per Common Unit to be sold in such offering, or would materially adversely affect the timing of such registration or takedown, then the Piggyback Registration Notice shall so state and the Holders shall have no right to participate in such offering or takedown. In addition, if a Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary Underwritten Offering on behalf of the Partnership and the Managing Underwriter(s) advises the Partnership and the Holders (if any Holders have elected to include Registrable Securities in such Piggyback Registration or Piggyback Shelf Takedown) in writing prior to the launch of such offering that in its reasonable and good faith opinion the number of Common Units proposed to be included in such registration or takedown, including all Registrable Securities and all other Common Units proposed to be included in such underwritten offering, exceeds the number of Common Units that can be sold in such offering and/or that the number of Common Units proposed to be included in any such registration or takedown would adversely affect the price per Common Unit to be sold in such offering, the Partnership shall include in such registration or takedown (i) first, the Common Units that the Partnership proposes to sell; and (ii) second, the Common Units requested to be included therein by Holders and by holders of Common Units other than Holders of Registrable Securities having registration rights with respect to such registration or takedown, allocated pro rata among all such holders on the basis of the number of Common Units owned by each such holder as to which the Partnership has received written requests for inclusion in such registration or takedown.

(c) If a Piggyback Registration or Piggyback Shelf Takedown is initiated as an Underwritten Offering on behalf of a holder of Common Units other than Registrable Securities, and the Managing Underwriter(s) advises the Partnership in writing that in its reasonable and good faith opinion, the inclusion of any Common Units in such registration or takedown other than the Common Units of such holder, would exceed the number of Common Units that can be sold in such offering or would materially adversely affect the price per Common Unit to be sold

in such offering, or would materially adversely affect the timing of such registration or takedown, then the Piggyback Registration Notice shall so state and the Holders shall have no right to participate in such registration or takedown. In addition, if a Piggyback Registration or Piggyback Shelf Takedown is initiated as an Underwritten Offering on behalf of a holder of Common Units other than Registrable Securities, and the Managing Underwriter(s) advises the Partnership in writing prior to the launch of such offering that in its reasonable and good faith opinion, the number of Common Units proposed to be included in such registration or takedown, including all Registrable Securities and all other Common Units proposed to be included in such underwritten offering, exceeds the number of Common Units that can be sold in such offering and/or that the number of Common Units proposed to be included in any such registration or takedown would adversely affect the price per Common Unit to be sold in such offering, the Partnership shall include in such registration or takedown (i) first, the Common Units requested to be included therein by the holder(s) requesting such registration or takedown and; and (ii) second, the Common Units requested to be included therein by holders (including Holders) of Common Units having registration rights with respect to such registration or takedown other than the holder(s) requesting such registration or takedown, allocated pro rata among all such holders on the basis of the number of Common Units owned by each such holder or in such manner as they may otherwise agree.

(d) If any Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary Underwritten Offering on behalf of the Partnership, the Partnership shall select the Managing Underwriter(s) in connection with such offering.

(e) The Partnership may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion.

Section 2.05. Sale Procedures. In connection with its obligations under this Article II, the Partnership will, as expeditiously as possible (subject to Section 2.04(e) in the case of a Piggyback Registration):

(a) cause each Registration Statement or Piggyback Registration Statement (and the documents incorporated therein by reference), at the time such registration statement or any part thereof becomes effective, (i) to comply as to form in all material respects with all applicable requirements of the Securities Act and (ii) not to 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 provided, however, that the obligations of the Partnership under this Section 2.05(a)(ii) will not be applicable with respect to information furnished by a Selling Holder, its directors, officers, employees and agents or controlling Persons described in Section 2.08(a) in writing specifically for use in a Registration Statement or a Piggyback Registration Statement.

(b) prepare and file with the Commission such amendments and supplements to each Registration Statement or Piggyback Registration Statement and the prospectus used in connection therewith as may be necessary to keep each Registration Statement or Piggyback Registration Statement effective for the Effectiveness Period, in the case of a Registration Statement, 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 or Piggyback Registration Statement;

(c) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering and the Managing Underwriter(s) notifies the Partnership in writing that, in the sole judgment of such Managing Underwriter(s), inclusion of detailed information in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, use its commercially reasonable efforts to include such information in such prospectus supplement;

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

(e) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Registration Statement or Piggyback Registration Statement 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(s), 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 jurisdiction where it is not then so subject;

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

(g) immediately notify each Selling Holder and each underwriter, at any time when a prospectus is required to be delivered 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 Piggyback Registration Statement, 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 in

order to make the statements therein not misleading (in the case of the prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement or Piggyback Registration Statement, 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 in order to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(j) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(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 participating therein, its directors, officers, employees and agents, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), and its directors, officers, employees or agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, director, officer, employee, agent or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether

commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus or any Written Testing-the-Waters Communication, in the light of the circumstances under which such statement is made) contained in any Written Testing-the-Waters Communication, a Registration Statement, a Piggyback Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or any Written Testing-the-Waters Communication, in the light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors, officers, employee and agents, and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings as such expenses are incurred; 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, its directors, officers, employees and agents or such controlling Person in writing specifically for use in any Written Testing-the-Waters Communication, a Registration Statement, a Piggyback Registration Statement or prospectus or any amendment or supplement thereto, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such directors, officers, employees agents or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, its directors, officers, employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, 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 any Written Testing-the-Waters Communication, a Registration Statement, a Piggyback Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof; 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.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party other than under this Section 2.08. In any action brought against any indemnified party, the indemnified party 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 acceptable 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, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. In addition, notwithstanding any other provisions of this Agreement, an indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (such consent not to be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.

(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 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 Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other 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 the 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 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 or defending 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 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 sale of the Registrable Securities to the public 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, 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 Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, unless otherwise available via ▇▇▇▇▇ or on the Partnership’s website, furnish to such Holder promptly 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 granted to a Holder by the Partnership under this Article II may be transferred or assigned by such Holder to one or more transferee(s) or assignee(s) of such Registrable Securities; provided, however, that (a) unless such transferee or assignee is an Affiliate of a Contributor Party, such transferee or assignee holds Registrable Securities representing at least five percent (5%) of the then-outstanding Registrable Securities, (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 Registrable Securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee agrees to be bound by this Agreement, including the provisions hereof imposing limitations on the rights of Holders to cause the registration of Registrable Securities or the terms and conditions of such registration.

Section 2.11. Restrictions on Public Sale by Holders of Registrable Securities. Each Contributor Party and any other Holder(s) who, along with its Affiliates, holds at least five percent (5%) of the then-outstanding Registrable Securities (subject to adjustment pursuant to Section 3.04), agrees to enter into a customary letter agreement with underwriters providing that such Holder will not effect any public sale or distribution of the Registrable Securities during the 90 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Partnership or the officers, directors or any other unitholder of the Partnership on whom a restriction is imposed in connection with the Underwritten Offering, and such restrictions shall not otherwise be more restrictive than such restrictions so generally imposed by the underwriters, and (ii) the restrictions set forth in this Section 2.11 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder.

Section 2.12. Additional Restrictions. The rights granted under this Agreement to the Contributor Parties and to any other Holders of Registrable Securities shall be subject in all respect to the restrictions provided for in Section 5.8 of the Contribution Agreement. For avoidance of doubt, although all of the Registrable Securities may be registered pursuant to Section 2.01 during the Lock-up Period, the Selling Holder’s rights to sell, transfer or otherwise dispose of the Registrable Securities pursuant to a Registration Statement shall continue to be subject to the restrictions contained in Section 5.8 of the Contribution Agreement.

Section 2.13. No Inconsistent Agreements. The Partnership will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Partnership’s securities under any agreement in effect on the date hereof.

Section 3.02. Successor and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including subsequent Holders of Registrable Securities to the extent permitted herein.

Section 3.03. Assignment of Rights. All or any portion of the rights and obligations of the Holders under this Agreement may be transferred or assigned by the Holders in accordance with Section 2.10 hereof.

Section 3.05. Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each party in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent 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 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 party from pursuing any other rights and remedies at law or in equity that such party may have.

Section 3.06. 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 3.08. Governing Law. The laws of the State of Delaware shall govern this Agreement. Each of the parties hereto agrees (a) that this Agreement involves at least $100,000.00, and (b) that this Agreement has been entered into by the parties hereto in express reliance upon 6 Del. C. § 2708. Each of the parties hereto hereby irrevocably and unconditionally agrees (i) that it is and shall continue to be subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (ii)(A) to the extent that such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process and notify the other parties hereto of the name and address of such agent, and (B) to the fullest extent permitted by law, that service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by the U.S. Postal Service constituting evidence of valid service, and that, to the fullest extent permitted by applicable law, service made pursuant to (ii)(A) or (B) above shall have the same legal force and effect as if served upon such party personally within the State of Delaware. This Agreement may be executed in several counterparts, each of which shall be considered an original but which together shall be deemed one and the same instrument. An executed copy of this Agreement delivered by facsimile, email or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original executed copy of this Agreement.

Section 3.09. Severability of Provisions. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or enforceability of such provision in any other jurisdiction.

Section 3.10. Scope of Agreement. The rights granted pursuant to this Agreement are intended to supplement and not to reduce or replace any rights any Holders may have under the Partnership Agreement with respect to the Registrable Securities.

statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. Except as provided in the Partnership Agreement, there are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by the Partnership set forth herein. Except as provided in the Partnership Agreement, this Agreement supersedes 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 a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder.

Section 3.12. No Presumption. If any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

Section 3.13. Aggregation of Registrable Securities. All Registrable Securities held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

Section 3.14. Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no Person other than the Partnership and the Holders shall have any obligation hereunder and that, notwithstanding that one or more of the Holders may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith 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 the Holders 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 the Holders 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 the Holders under this Agreement or any documents or instruments delivered in connection herewith or therewith 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 the Holders hereunder.

Section 3.15. Interpretation. All references to “Articles” and “Sections” shall be deemed to be references to Articles and Sections of this Agreement, unless otherwise specified. 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.” Whenever any determination, consent or approval is to be made or given by the Holders under this Agreement, such action shall be in the Holders’ sole discretion unless otherwise specified.
