     (b) Until the Option Closing Date, if any, before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the

Prospectus, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule.

     (e) If the Time of Sale Prospectus is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

     (f) If, during such period after the first date of the public offering of the Units as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and

to the dealers (whose names and addresses you will furnish to the Partnership) to which Units may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

     (g) To endeavor to qualify the Units for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request.

     (h) To make generally available to the Partnership’s security holders and to you as soon as practicable an earning statement covering a period of at least twelve months beginning with the first fiscal quarter of the Partnership occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

     (i) Not, at any time at or after the execution of this Agreement, to, directly or indirectly, offer or sell any Units by means of any “prospectus” (within the meaning of the Securities Act), or use any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Units, in each case other than the Prospectus.

      8. Certain Covenants of the Selling Unitholders. Each Selling Unitholder hereby severally and not jointly agrees:

     (a) Not, at any time at or after the execution of this Agreement, to offer or sell any Units by means of any “prospectus” (within the meaning of the Securities Act), or use any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Units, in each case other than the Prospectus; provided , however , that, following the expiration of the Lock-Up Period pursuant to the Lock-Up Agreement entered into by such Selling Unitholder, no sale or other transfer of any Units not purchased by the Underwriters pursuant to this Agreement upon the expiration of the 30-day option provided in Section 3 shall be deemed a breach of this covenant.

     (c) To pay or cause to be paid all taxes, if any, on the transfer and sale of the Units being sold by such Selling Unitholder.

     (d) To advise you promptly, and if requested by you, confirm such advice in writing, so long as a prospectus is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) in connection with any sale of Units, of (i) any material change known to such Selling Unitholder in the business, properties, financial condition, results of operations or prospects of the Partnership and the Subsidiaries taken as a whole, (ii) any change in information in the Registration Statement, the Time of Sale Prospectus, the Prospectus relating to such Selling Unitholder or (iii) any new material information relating to the Partnership or relating to any matter stated in the Registration Statement, the Time of Sale Prospectus and the Prospectus that comes to the attention of such Selling Unitholder.

     (e) Prior to or concurrently with the execution and delivery of this Agreement, to execute and deliver to the Underwriters a Custody Agreement and a Lock-Up Agreement.

     9.  Expenses . Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the ETE Entities agree to pay or cause to be paid all expenses incident to the performance of its and the Selling Unitholders obligations under this Agreement, including: (i) the fees, disbursements and expenses of the ETE Entities’ counsel, the ETE Entities’ accountants and Hunton & Williams, LLP, counsel for the Selling Unitholders, in connection with the registration and delivery of the Units under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the ETE Entities and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Units to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Units under state securities laws and all expenses in connection with the qualification of the Units for offer and sale under state securities laws as provided in Section 7(g) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Units by FINRA, (v) all costs and expenses incident to listing the Units on the NYSE, (vi) the cost of printing certificates representing the Units, (vii) the costs and charges

     The provisions of this Section shall not supersede or otherwise affect any agreement that the ETE Entities and Selling Unitholders may otherwise have for the allocation of such expenses among themselves.

     10.  Covenants of the Underwriters . Each Underwriter severally covenants with the ETE Entities not to take any action that would result in the Partnership being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Partnership thereunder, but for the action of the Underwriter.

     11.  Indemnity and Contribution . (a) The ETE Entities jointly and severally agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Partnership information that the Partnership has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar

as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Partnership in writing by such Underwriter through you expressly for use therein.

     (b) Each Selling Unitholder agrees, severally and not jointly, to indemnify and hold harmless the Underwriters and each person, if any, who controls the Underwriters within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Partnership information that the Partnership has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus (as amended or supplemented if the Partnership shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Selling Unitholder furnished to the Underwriters or the Partnership in writing by such Selling Unitholder through you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto.

     (c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the ETE Entities, the Selling Unitholders, the directors of the General Partner, the officers of the General Partner who sign the Registration Statement and each person, if any, who controls the ETE Entities or any Selling Unitholder within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Partnership information that the Partnership has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus (as amended or supplemented if the Partnership shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Underwriter furnished to the Partnership in writing by such Underwriter through you expressly

for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto.

     (d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11, 11(b) or 11(c), such person (the “ indemnified party ”) shall promptly notify the person against whom such indemnity may be sought (the “ indemnifying party ”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Partnership, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Partnership within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Unitholders and all persons, if any, who control any Selling Unitholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Morgan Stanley. In the case of any such separate firm for the Partnership, and such directors, officers and control persons of the Partnership, such firm shall be designated in writing by the Partnership. In the case of any such separate firm for the Selling Unitholders and such control persons of any Selling Unitholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Unitholders under the Powers of Attorney. The indemnifying party 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 party agrees to indemnify the indemnified party from and against

any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

     (e) To the extent the indemnification provided for in Section 11, 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Units or (ii) if the allocation provided by clause 11(e) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(e) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand 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 ETE Entities and Selling Unitholders on the one hand and the Underwriters on the other hand in connection with the offering of the Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Units (before deducting expenses) received by each Selling Unitholder and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Units. The relative fault of the ETE Entities and Selling Unitholders on the one hand and the Underwriters 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 relates to information supplied by the ETE Entities or Selling Unitholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to

contribute pursuant to this Section 11 are several in proportion to the respective number of Units they have purchased hereunder, and not joint.

     (f) The ETE Entities, Selling Unitholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters 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 Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter 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 remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

     (g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the ETE Entities and the Selling Unitholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, any Selling Unitholder or any person controlling any Selling Unitholder, or the ETE Entities, their respective officers or directors or any person controlling any of the ETE Entities and (iii) acceptance of and payment for any of the Units.

     (h) Notwithstanding the foregoing, no Selling Unitholder shall be liable for indemnification or contribution payments pursuant to this Agreement in an amount in excess of the product resulting from the multiplication of the Purchase Price by the number of Units sold hereunder by such Selling Unitholder.

     12.  Termination . The Underwriters may terminate this Agreement by notice given by you to the ETE Entities, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the NYSE or the NASDAQ Global Market, (ii) trading of any securities of the Partnership shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking

activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause 12, makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Units on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

     13.  Effectiveness; Defaulting Underwriters . This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Units that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Units to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Units set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Units that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Units without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Units and the aggregate number of Firm Units with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Units to be purchased on such date, and arrangements satisfactory to you, the ETE Entities and the Selling Unitholders for the purchase of such Firm Units are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the ETE Entities or the Selling Unitholders. In any such case either you or the relevant Selling Unitholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Units and the aggregate number of Additional Units with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Units to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Units to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Units that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this

paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of any of the ETE Entities or Selling Unitholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the ETE Entities or any Selling Unitholder shall be unable to perform its obligations under this Agreement, the ETE Entities or such Selling Unitholder, whichever party is the cause of such termination, will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

     14.  Entire Agreement . (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Units, represents the entire agreement between the Partnership and the Selling Unitholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Units.

     (b) The ETE Entities acknowledge that in connection with the offering of the Units: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the ETE Entities or any other person, (ii) the Underwriters owe the ETE Entities only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the ETE Entities. The ETE Entities waive to the full extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Units.

     15.  Counterparts . This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

     16.  Applicable Law; Jurisdiction; Waiver of Jury Trial . Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the ETE Entities and the Selling Unitholders each consent to the jurisdiction of such courts and personal service with respect thereto. The ETE Entities and the Selling Unitholders each hereby consent to personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any

indemnified party. Each Underwriter and the ETE Entities (on its behalf and, to the extent permitted by applicable law, on behalf of its partners and affiliates) and each Selling Unitholder (on its behalf and, in the case such Selling Unitholder is not an individual, to the extent permitted by applicable law, on behalf of its equity holders and affiliates) each waive all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The ETE Entities and the Selling Unitholders each agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the ETE Entities and each Selling Unitholder and may be enforced in any other courts to the jurisdiction of which the ETE Entities or any Selling Unitholder is or may be subject, by suit upon such judgment.

     17.  Headings . The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

Ladies and Gentlemen:

          The undersigned understands that Morgan Stanley & Co. Incorporated, Citigroup Global Markets Inc. and UBS Securities LLC (the “ Representatives ”) propose to enter into an Underwriting Agreement (the “ Underwriting Agreement ”) with Energy Transfer Equity, L.P., a Delaware limited partnership (the “ Partnership ”), the Selling Unitholders named therein and the other underwriters named in Schedule II to the Underwriting Agreement (together with the Representatives, the “ Underwriters ”), providing for the public offering (the “ Public Offering ”) of common units representing limited partner interests of the Partnership (the “ Units ”).

          To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, for a period (the “ Lock-Up Period ”) beginning on the date hereof and ending on, and including, the date that is 90 days after the date of the final prospectus supplement relating to the Public Offering, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “ Commission ”) in

respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “ Exchange Act ”) with respect to, any Units or any other securities of the Partnership that are substantially similar to Units, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Units or any other securities of the Partnership that are substantially similar to Units, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, whether any such transaction is to be settled by delivery of Units or such other securities, in cash or otherwise or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii) . The foregoing sentence shall not apply to (a) the registration of the offer and sale of Units as contemplated by the Underwriting Agreement and the sale of the Units to the Underwriters (as defined in the Underwriting Agreement) in the Public Offering, (b) transfers required by law, (c) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (d) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement or (e) transfers of Units by any holder of a Unit to any affiliate or any transferee in a private transaction, in each case who delivers a written instrument agreeing to be bound by the terms of this Lock-Up Agreement, provided that no filing under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of shares of Units, shall be required or shall be voluntarily made in respect of the transfer or distribution during the 90-day Lock-Up Period. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

          Notwithstanding anything herein to the contrary, the preceding paragraph shall not apply to the sale of Firm Units (as defined in the Underwriting Agreement) or Additional Units (as defined in the Underwriting Agreement) by any Selling Unitholder to the Underwriters pursuant to the Underwriting Agreement.

          In addition, the undersigned hereby waives any rights the undersigned may have to require registration of Units in connection with the filing of a registration statement relating to the Public Offering. The undersigned further agrees that, for the Lock-Up Period, the undersigned will not, without the prior written consent of the Representatives, make any demand for, or exercise any right with respect to, the registration of Units or any securities convertible

into or exercisable or exchangeable for Units, or warrants or other rights to purchase Units or any such securities.

          The undersigned hereby confirms that the undersigned has not, directly or indirectly, taken, and hereby covenants that the undersigned will not, directly or indirectly, take, any action designed, or which has constituted or will constitute or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of Units.

* * *

          If (i) the Partnership notifies you in writing that it does not intend to proceed with the Public Offering, (ii) the registration statement filed with the Commission with respect to the Public Offering is withdrawn or (iii) for any reason the Underwriting Agreement shall be terminated prior to the “time of purchase” (as defined in the Underwriting Agreement), this Lock-Up Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.

FORM OF OPINION FROM VINSON & ELKINS, LLP

     1. Each of the Energy Transfer Entities has been duly formed and is validly existing and in good standing as a limited partnership or limited liability company, as the case may be, under the laws of its respective jurisdiction of formation, with all partnership or limited liability company power and authority necessary to own or lease, as the case may be, and operate its properties and conduct its business in each case as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, and (i), in the case of the General Partner, to act as the General Partner of the Partnership, (ii) in the case of ETP GP LLC, to act as the general partner of ETP GP LP, (iii) in the case of ETP GP LP, to act as the general partner of ETP and HOLP, (iv) in the case of LA GP, to act as the general partner of ETC OLP, (v) in the case of Heritage ETC to act as the sole member of ETIH OLP, (vi) in the case of Titan GP to act as the sole general partner of Titan OLP, and (vii) in the case of each of the ETE Parties, to perform its obligations under the Underwriting Agreement.

     2. The General Partner is the sole general partner of the Partnership and, as of the Closing Date, the General Partner will own a 0.30915% general partner interest in the Partnership (the “ GP Interest ”); such GP Interest has been duly authorized and validly issued in accordance with the Partnership Agreement, as in effect at the time of purchase, and the General Partner owns such general partner interest free and clear of all Liens (a) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as debtor on file in the office of the Secretary of State of the State of Delaware or (b) otherwise known to us without independent investigation, other than those created by or arising under Sections 17-303(a) and 17-607 of the Delaware LP Act.

     3. The Underwriting Agreement has been duly authorized, executed and delivered by the ETE Entities. Each of the ETE Entities has all requisite right, power and authority to execute and deliver the Underwriting Agreement and to perform its respective obligations thereunder. All partnership and limited liability company action, as the case may be, required to be taken by the ETE Entities or any of their security holders, partners or members for (a) the authorization, sale and delivery of the Units, (b) the due and proper authorization, execution and delivery of the Underwriting Agreement and (c) the consummation of the transactions contemplated by the Underwriting Agreement has been duly and validly taken.

     4. The Units to be sold by the Selling Unitholders pursuant to the Underwriting Agreement have been duly authorized and validly issued and are fully paid (to the extent required under the Partnership Agreement) and non-assessable (except as such nonassessability may be affected by Sections 17-303 and 17-607 of the Delaware LP Act).

     5. The equity securities of the Partnership, including the Units, conform in all material respects to the description thereof, if any, contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus.

     6. The Registration Statement was declared effective under the Securities Act on October 23, 2007; to such counsel’s knowledge, no stop order proceedings with respect thereto are pending or threatened under the Securities Act; and any required filing of the Prospectus and any supplement thereto pursuant to Rule 424 or Rule 430B under the Securities Act has been made in the manner and within the time period required by such Rule 424 and in compliance with Rule 430B and Rule 430A under the Act.

     7. The Registration Statement, the Time of Sale Prospectus and the Prospectus (except for the financial statements and the notes and schedules thereto and the other financial or statistical information included in the Registration Statement, the Time of Sale Prospectus and the Prospectus or amendments or supplements thereto, as to which such counsel need not express an opinion), appear on their face to comply as to form in all material respects with the requirements of the Securities Act (including, in the case of the Prospectus, Section 10(a) of the Act) and the rules and regulations promulgated thereunder.

     8. No approval, authorization, consent or order under any federal law, the laws of the State of New York or Delaware, or approval, authorization, consent of or filing with any New York or Delaware governmental or regulatory commission, board, body, authority or agency, in each case as applicable to any of the ETE Entities, is required in connection with the sale of the Units to be sold by the Selling Unitholders pursuant to the Underwriting Agreement or with the consummation of the transactions contemplated by the Underwriting Agreement other than registration of the Units under the Securities Act, which has been effected (except that we express no opinion as to any necessary qualification under the state securities or blue sky laws of the various jurisdictions in which the Units are being offered by the Underwriters and we express no opinion with respect to the Conduct Rules of the FINRA).

     9. The execution, delivery and performance of the Underwriting Agreement by the ETE Entities, the sale of the Units to be sold by the Selling Unitholders pursuant to the Underwriting Agreement and the consummation of the transactions contemplated by the Underwriting Agreement do not and will not result in any breach or violation of or constitute a default under (nor constitute any event which, with notice, lapse of time or both, would result in any breach or violation of or constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under) (or result in

the creation or imposition of a lien, charge or encumbrance on any property or assets of the Energy Transfer Entities pursuant to) (i) the certificate of limited partnership or agreement of limited partnership, certificate of formation or limited liability company agreement or other organizational documents of the Energy Transfer Entities, or (ii) any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument (collectively, “ Agreements and Instruments ”) which is filed as an exhibit to the Registration Statement, Prospectus or any Incorporated Document, or (iii) federal laws, the laws of the State of New York or the Delaware LP Act, or (iv) any governmental decree, judgment or order applicable to the Energy Transfer Entities or any of their respective properties, which decree, judgment or order is identified to such counsel by any of the ETE Entities as being material to the Energy Transfer Entities as a whole, excluding those breaches, violations, defaults or liens, in the case of clause (ii), that would not reasonably be expected to have a Material Adverse Effect or could not materially impair the ability of any of the ETE Entities to perform their obligations under the Underwriting Agreement; provided , however , that no opinion is expressed pursuant to this paragraph with respect to federal or state securities laws, tax laws or antifraud laws.

     10. Neither of the Partnership or ETP is and, after giving effect to the offering and sale of the Units, neither will be an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

     11. The statements in the Registration Statement, the Time of Sale Prospectus and the Prospectus under the headings “Description of Our Common Units” “Material Provisions of Our Partnership Agreement,” “Material Provisions of ETP’s Partnership Agreement,” and “Material Tax Consequences”, insofar as such statements constitute summaries of documents or legal proceedings or refer to matters of law or legal conclusions, are accurate and complete in all material respects; and the Units conform as to legal matters in all material respects to the descriptions thereof contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus.

     12. The opinion of Vinson & Elkins LLP that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely upon such opinion as if it were addressed to them

     13. Such counsel has participated in conferences with officers and other representatives of the Energy Transfer Entities, representatives of the independent public accountants of the Energy Transfer Entities, representatives of the Selling Unitholders and representatives of the Underwriters at which the contents of the Registration Statement, the Time of Sale Prospectus and the Prospectus were discussed and, although such counsel need not pass upon and

need not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus (except as and to the extent stated in subparagraphs 8 , 9 and 25 above), on the basis of the foregoing, nothing has come to the attention of such counsel that causes such counsel to believe that (i) the Registration Statement, at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Time of Sale Prospectus (together with (a) the aggregate number of Offered Units offered for sale pursuant to the Prospectus and the number of such Offered Units being offered by each of the Selling Unitholders and (b) the public offering price per unit, in the case of each of clause (a) and clause (b), as reflected on the cover page of the Prospectus), as of as of the date of this Agreement or as amended or supplemented, if applicable, as of the Closing Date, included an untrue statement of a material fact or omitted 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 or (iii) the Prospectus, as of its date or as amended or supplemented, if applicable, as of the Closing Date, included or includes an untrue statement of a material fact or omitted or omits 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 (it being understood that such counsel need not express any opinion in this paragraph 27 with respect to the financial statements and schedules, and other financial data derived therefrom, included in the Registration Statement, the Time of Sale Prospectus or the Prospectus).
