 References herein to:

indirect, wholly owned subsidiary of Equitrans following the EQM Merger. In connection with the closing of the EQM Merger, the Partnership will subsequently amend and restate its Partnership Agreement, to among other things, reflect the EQM Merger,
including the Partnership becoming a wholly-owned subsidiary of Equitrans and the delisting of all registered securities of the Partnership, including its Common Units (as defined below) and its outstanding registered senior notes.

Preferred Units treated as Common Units on an as-converted basis, voting together as a single class at a special meeting of the limited partners of the Partnership (the “EQM Special Meeting”),

“Equitrans Special Meeting,” together with the EQM Special Meeting, the “Special Meetings”) and (iii) certain other conditions that may not be satisfied or completed on a timely basis, if at all. The Special
Meetings were held on June 15, 2020, and, the required approvals were obtained.

Offering Memorandum will be, delivered by the Partnership to the Initial Purchasers pursuant to the terms of this purchase agreement (the “Agreement”). The Partnership hereby confirms that it has authorized the use of the

(B)    in accordance with the restrictions set forth in Annex C hereto. 

(c)    Each Initial Purchaser acknowledges and agrees that the Partnership and, for purposes of the “no

(g)    The Partnership acknowledges and agrees that each Initial Purchaser is acting solely in the capacity of an
arm’s length contractual counterparty to the Partnership with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an
agent of, the Partnership or any other person. Additionally, neither the Representative nor any other Initial Purchaser is advising the Partnership or any other person as to any legal, tax, investment, accounting or regulatory matters in any
jurisdiction. The Partnership shall consult with its own advisors concerning such matters 

  
 4 












 
and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Initial Purchasers shall have no responsibility or liability
to the Partnership with respect thereto. Any review by the Representative or any Initial Purchaser of the Partnership and the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of
the Representative or such Initial Purchaser, as the case may be, and shall not be on behalf of the Partnership or any other person. 

3.    Representations and Warranties of the Partnership. The Partnership represents and warrants to each Initial
Purchaser that: 
 (a)    Preliminary Offering Memorandum, Time of Sale Information and Offering Memorandum. The
Preliminary Offering Memorandum, as of its date, did not, the Time of Sale Information, at the Time of Sale, did not, and on the Closing Date, will not, and the Offering Memorandum, in the form first used by the Initial Purchasers to confirm sales
of the Securities and as of the Closing Date, will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made,
not misleading; provided that the Partnership makes no representation or warranty with respect to any statements or omissions made in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the
Partnership in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the Time of Sale Information or the Offering Memorandum. 

(b)    Additional Written Communications. The Partnership (including its agents and representatives, other than the
Initial Purchasers in their capacity as such) has not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any written communication that constitutes an offer to sell or

Communication”) other than (i) the Preliminary Offering Memorandum, (ii) the Offering Memorandum, (iii) the documents listed on Annex A hereto, including a term sheet substantially in the form of Annex B hereto, which
constitute part of the Time of Sale Information, and (iv) any electronic road show or other written communications, in each case used in accordance with Section 4(c) hereof. Each such Issuer Written Communication, when taken together with

circumstances under which they were made, not misleading; provided that the Partnership makes no representation or warranty with respect to any statements or omissions made in each such Issuer Written Communication in reliance upon and in

respects to the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, and did not and will 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 the light of the circumstances under which they were made, not misleading.

(B) the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded the Securities or any other debt securities or preferred stock issued or guaranteed by any of the Partnership Entities by any
“nationally recognized statistical rating organization,” as such term is defined under Section 3(a)(62) under the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review,
or has changed its outlook with respect to, its rating of the Securities or of any other debt securities or preferred stock issued or guaranteed by the Partnership Entities (other than an announcement with positive implications of a possible
upgrading). 
 (c)    No Material Adverse Change. No event or condition of a type described in Section 3(e)
hereof shall have occurred or shall exist, which event or condition is not described in each of the Time of Sale Information (excluding any amendment or supplement thereto) and the Offering Memorandum (excluding any amendment or supplement thereto)
the effect of which in the judgment of the Representative makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale
Information and the Offering Memorandum. 
 (d)    Officer’s Certificate. The Representative shall have
received on and as of the Closing Date a certificate of an executive officer of the General Partner who has specific knowledge of the Partnership’s financial matters and is satisfactory to the Representative (i) confirming that such
officer has carefully reviewed the Time of Sale Information and the Offering Memorandum and, to the knowledge of such officer, the representations set forth in Sections 3(a) and 3(b) hereof are true and correct, (ii) confirming that the other
representations and warranties of the Partnership in this Agreement are true and correct and that the Partnership has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the
Closing Date and (iii) to the effect set forth in paragraphs (b) and (c) (provided that no representation with respect to the judgment of the Representative need be made) above. 

  
 25

substance reasonably satisfactory to the Representative, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain

telecommunication from the appropriate governmental authorities of such jurisdictions. 
 (k)    DTC. The
Securities shall be eligible for clearance and settlement through DTC. 

  
 26 












 (l)    Indenture and Securities. The Indenture shall have been

Trustee. 
 (m)    Additional Documents. On or prior to the Closing Date, the Partnership shall have furnished to
the Representative such further certificates and documents as the Representative may reasonably request. 
 All opinions, letters,
certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers. 

7.    Indemnification and Contribution. 

(a)    Indemnification of the Initial Purchasers. The Partnership agrees to indemnify and hold harmless each
Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are reasonably incurred),
joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication
or the Offering Memorandum (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made,
not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any
information relating to any Initial Purchaser furnished to the Partnership in writing by such Initial Purchaser through the Representative expressly for use therein. 

(b)    Indemnification of the Partnership. Each Initial Purchaser agrees, severally and not jointly, to indemnify
and hold harmless the Partnership, each of the General Partner’s directors and officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Partnership in writing by such Initial Purchaser through the Representative expressly for use


  
 27 












 
in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being
understood and agreed that the only such information consists of the following paragraphs in the Preliminary Offering Memorandum and the Offering Memorandum: (i) the third paragraph, (ii) the fourth sentence of the seventh paragraph and
(iii) the eighth paragraph, in each case, under the caption “Plan of distribution.” 
 (c)    Notice
and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either
paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that
the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b)
above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who
shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to
retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the
Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are
different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and the Indemnified
Person shall have reasonably concluded that the representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and
expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by J.P.


  
 28 












 
Morgan Securities LLC and any such separate firm for the Partnership, its directors and officers and any control persons of the Partnership shall be designated in writing by the Partnership. The
Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each
Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the
Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more
than 45 days after receipt by the Indemnifying Person of such request, (ii) the Indemnifying Person shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) the
Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of
any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional
release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 

(d)    Contribution. If the indemnification provided for in paragraph (a) or (b) above is unavailable to an
Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and the Initial
Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in
clause (i) but also the relative fault of the Partnership on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Partnership on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses)
received by the Partnership from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities.
The relative fault of the Partnership on 

  
 29 












 
the one hand and the Initial Purchasers 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 relates to information supplied by the Partnership or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. 
 (e)    Limitation on Liability. The Partnership and the Initial Purchasers agree that it would not
be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does
not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event
shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages
that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their
respective purchase obligations hereunder and not joint. 

(f)    Non-Exclusive Remedies. The remedies provided for in this
Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. 

8.    Effectiveness of Agreement. This Agreement shall become effective as of the date first written above. 

9.    Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to
the Partnership, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by any of the Partnership Entities shall have been suspended on any exchange or in any over-the-counter market (other than any delisting of registered securities of the Partnership, including the Partnership’s Common Units and its outstanding registered
senior notes, in connection with the EQM Merger); (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State 

  
 30 












 
authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United
States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement,
the Time of Sale Information and the Offering Memorandum. 
 10.    Defaulting Initial Purchaser. 

(a)    If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has
agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Partnership on the terms contained
in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Partnership shall be
entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated
or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Partnership may postpone the Closing Date for up to five full business days in order
to effect any changes that in the opinion of counsel for the Partnership or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Partnership
agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this
Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase. 

(b)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or
Initial Purchasers by the non-defaulting Initial Purchasers and the Partnership as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not
exceed one-eleventh of the aggregate principal amount of all the Securities, then the Partnership shall have the right to require each non-defaulting Initial Purchaser
to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed
to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made. 

(c)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or
Initial Purchasers by the non-defaulting Initial Purchasers and the Partnership as provided in paragraph (a) above, the 

  
 31 












 
aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if
the Partnership shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination
of this Agreement pursuant to this Section 10 shall be without liability on the part of the Partnership, except that the Partnership will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that
the provisions of Section 7 hereof shall not terminate and shall remain in effect. 
 (d)    Nothing contained
herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Partnership or any non-defaulting Initial Purchaser for damages caused by its default. 

11.    Payment of Expenses. 

(a)    Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the
Partnership agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery
of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering
Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Partnership’s counsel and
independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may
designate and the preparation, printing and distribution of a Blue Sky Memorandum (including reasonable and documented related fees and expenses of counsel for the Initial Purchasers not to exceed $20,000); (vi) any fees charged by rating
agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the
approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Partnership in connection with any “road show” presentation to potential investors. Except as provided in Section 7 and this
Section 11(a) and in Section 11(b), the Initial Purchasers shall pay their own expenses, including the fees and disbursements of their counsel, transfer taxes on any resale of the Securities by any Initial Purchaser, any advertising
expenses connected with any offers they may make and other expenses incurred by the Initial Purchasers on their own behalf in connection with presentations to prospective purchasers of the Securities. 

  
 32 












 (b)    If (i) this Agreement is terminated pursuant to
Section 9(i) or Section 9(ii) hereof, (ii) the Partnership for any reason fails to tender the Securities for delivery to the Initial Purchasers (other than by reason of a default by any of the Initial Purchasers except pursuant to
Section 10(c)) or (iii) any condition to the obligations of the Initial Purchasers contained herein for the Closing Date is not met or waived, the Partnership agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) incurred by the Initial Purchasers in connection with this Agreement and the
offering contemplated hereby. 
 12.    Persons Entitled to Benefit of Agreement. This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Initial Purchaser referred to in Section 7 hereof.
Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial
Purchaser shall be deemed to be a successor merely by reason of such purchase. 
 13.    Survival. The respective
indemnities, rights of contribution, representations, warranties and agreements of the Partnership and the Initial Purchasers contained in this Agreement or made by or on behalf of the Partnership or the Initial Purchasers pursuant to this Agreement
or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the
Partnership or the Initial Purchasers. 
 14.    Certain Defined Terms. For purposes of this Agreement,
(a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks
are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; (d) the term “Exchange Act” collectively means the
Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder; and (e) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act. 

15.    Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which
information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients. 

  
 33

hereafter have to the laying of venue of any such suit or proceeding in such courts. The Partnership agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Partnership and may
be enforced in any court to the jurisdiction of which Company is subject by a suit upon such judgment. 

(e)    Waiver of Jury Trial. Each of the parties hereto hereby waives any right to trial by jury in any suit or
proceeding arising out of or relating to this Agreement. 
 (f)    Recognition of the U.S. Special Resolution

 (i) In the event that any Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a
U.S. Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special
