ARTICLE II 
 REGISTRATION
RIGHTS 
 Section 2.01 Shelf Registration. 

(a) Shelf Registration. ETP shall prepare and file a registration statement under the Securities Act to permit the public resale of the
Registrable Securities in accordance with Section 10.3 of the Contribution Agreement. ETP shall use its reasonable best efforts to cause the Shelf Registration Statement to be effective as soon as reasonably practicable thereafter (the
“Shelf Registration”); provided, however, that ETP shall not be required to effect more than one registration pursuant to this Section 2.01(a). The Shelf Registration Statement filed pursuant to this Section 2.01(a) shall be
on such appropriate registration form of the Commission as shall be selected by ETP. ETP will cause the Shelf Registration Statement filed pursuant to this Section 2.01(a) to be continuously effective under the Securities Act until all Registrable
Securities covered by the Shelf Registration Statement cease to be Registrable Securities pursuant to Section 1.02 (the “Effectiveness Period”). The Shelf Registration Statement, when declared effective (including the documents
incorporated therein by reference), will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein not misleading. 
 (b) Delay Rights.
Notwithstanding anything to the contrary contained herein, ETP may, upon written notice to any Selling Holder whose Registrable Securities are included in a Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which
is a part of such Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to such Shelf Registration Statement) for an aggregate period of not more than ninety (90) days in a
twelve-month period if ETP (i) is pursuing a financing, acquisition, merger, reorganization, disposition or other similar transaction and determines in good faith that its ability to pursue or consummate such a transaction would be materially
adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) has experienced some other material non-public event the non-disclosure of which at such time, in the good faith determination of ETP,
would render ETP unable to comply with applicable securities laws; provided, that such suspension shall apply to all holders of registration rights with respect to common units representing limited partner interests in ETP under this
Agreement or any other agreement or arrangement providing for registration rights. Upon disclosure of such information or the termination of the condition described above, ETP shall promptly (x) provide prompt notice to such Selling Holders, (y)
terminate any suspension of sales it has put into effect and (z) take such other actions to permit sales of Registrable Securities pursuant to such Shelf Registration Statement as contemplated in this Agreement. 

  
 3 








 Section 2.02 Registration Procedures. In connection with its obligations contained in
Section 2.01, ETP will, as expeditiously as possible: 
 (a) prepare and file with the Commission such amendments and supplements to the
Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by the Shelf Registration Statement; 
 (b) furnish to each Selling Holder (i)
as far in advance as reasonably practicable before filing the Shelf Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including furnishing or
making available exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission; provided, however, that ETP shall not be required to provide copies of Current Reports
on Form 8-K, Quarterly Reports on Form 10-Q, Annual Reports on Form 10-K, or other documents incorporated by reference in the Shelf Registration Statement that have been filed or furnished with 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 the Shelf Registration Statement or supplement or amendment thereto, and (ii) such number of copies of the Shelf 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 Shelf Registration Statement; 

(c) if applicable, use its reasonable best efforts to register or qualify the Registrable Securities covered by the Shelf Registration
Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request; provided that neither ETP nor any of its Affiliates will be required to qualify generally to transact business in any jurisdiction
where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject; 

(d) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act,
of (i) the filing of the Shelf 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 Shelf Registration Statement, 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 the Shelf Registration Statement or any prospectus or
prospectus supplement thereto; 
 (e) immediately notify each Selling Holder, at any time when a prospectus relating thereto 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 the Shelf 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 to make the statements therein not misleading, in the light of the circumstances then existing; (ii) the issuance or threat of issuance by


  
 4 








 
the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by ETP 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, ETP agrees to as promptly as
practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances then existing, and to take such other action as is necessary to remove a stop order, suspension, threat thereof or
proceedings related thereto; 
 (f) furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the
Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities; 

(g) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally
recognized quotation system on which similar securities issued by ETP are then listed; 
 (h) use its reasonable best efforts to cause the
Registrable Securities to be registered with or approved by such other Governmental Authorities as may be necessary by virtue of the business and operations of ETP to enable the Selling Holders to consummate the disposition of such Registrable
Securities; 
 (i) provide a transfer agent and registrar for all Registrable Securities covered by such Shelf Registration Statement not
later than the effective date of such Shelf Registration Statement; and 
 Each Selling Holder, upon receipt of notice from ETP of the
happening of any event of the kind described in subsection (e) of this Section 2.02, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended
prospectus contemplated by subsection (e) of this Section 2.02 or until it is advised in writing by ETP that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the
prospectus, and, if so directed by ETP, such Selling Holder will deliver to ETP (at ETP’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such notice. 
 Section 2.03 Cooperation by Holders. ETP shall
have no obligation to include in the Shelf Registration Statement Common Units of a Holder who has failed to timely furnish such information which, based upon the advice of counsel to ETP, is reasonably required in order for the Shelf Registration
Statement or any prospectus or prospectus supplement thereto, as applicable, to comply with the Securities Act. 

  
 5 








 Section 2.04 Expenses. ETP shall not be responsible for legal fees incurred by any of the
Holders in connection with the exercise of such Holders’ rights hereunder. ETP will pay all Registration Expenses in connection with any Shelf Registration Statement filed pursuant to Section 2.01(a), regardless of whether the Shelf
Registration Statement becomes effective or any sale is made pursuant to the Shelf Registration Statement. 
 Section 2.05
Indemnification. 
 (a) By ETP. In the event of a registration of any Registrable Securities under the Securities Act pursuant
to this Agreement, ETP will indemnify and hold harmless each Selling Holder thereunder, its directors and officers and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, against any
losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or controlling Person may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material
fact contained in the Shelf Registration Statement, any preliminary prospectus or final prospectus 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, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its
directors and officers and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that ETP 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 or
such controlling Person in writing specifically for use in the Shelf Registration Statement or any prospectus contained therein or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such Selling Holder or any such director, officer 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 ETP, its directors and
officers, and each Person, if any, who controls ETP within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from ETP 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 the Shelf Registration Statement or any prospectus contained therein or any amendment or supplement thereof relating to the Registrable Securities;
provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds received by such Selling Holder from the sale of the Registrable Securities giving rise to such
indemnification. 
 (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to any indemnified party other than under this Section 2.05. The indemnifying 

  
 6 








 
party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after
notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.05 for any legal expenses
subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to
assume the defense and employ counsel or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses
available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party,
then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of one such separate counsel (firm) 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 indemnified party shall settle any action brought against it with respect to
which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the
indemnifying party and further, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of such indemnified party,
unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 2.05 is held by a court or Governmental Authority of competent
jurisdiction to be unavailable to ETP or any Selling Holder or is insufficient to hold it harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Losses as between ETP on the one hand and such Selling Holder on the other hand, in such proportion as is appropriate to reflect the relative fault of ETP on the one hand and of such Selling
Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute
an aggregate amount in excess of the dollar amount of proceeds received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of ETP on the one hand and each Selling Holder on the
other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied
by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to
this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party
as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the
subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

  
 7 








 (e) Other Indemnification. The provisions of this Section 2.05 shall be in addition to any
other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise. 

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

(a) Make and keep public information regarding ETP 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
ETP under the Securities Act and the Exchange Act at all times from and after the date hereof; and 
 (c) So long as a Holder owns any
Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of ETP, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing such Holder to sell any such securities without registration. 
 Section 2.07 Transfer or
Assignment of Registration Rights. The rights to cause ETP to include Registrable Securities in a Shelf Registration Statement may be transferred or assigned by a Holder to one or more transferee(s) or assignee(s) of such Registrable Securities;
provided that (a) such transferee or assignee is an Affiliate of, or a direct or indirect investor in, such Holder or receives at least 20% of the Registrable Securities beneficially owned by such Holder as of the date of this Agreement, (b)
ETP is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each
such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Holder under this Agreement. 

Section 2.08 Information by Holder. Any Holder or Holders of Registrable Securities included in any Shelf Registration Statement shall
promptly furnish to ETP such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as ETP may reasonably request and as shall be required in connection with any registration, qualification or compliance
referred to herein.
