ARTICLE II.
REGISTRATION RIGHTS

     Section 2.01 Shelf Registration.

          (a) Shelf Registration. (a) At the option and upon the request of the holders of a majority of the Common Units covered by this Agreement, Regency shall prepare and file a registration statement under the Securities Act to permit the public resale of the Registrable Securities from time to time as permitted by Rule 415 (or any similar provision then in force) of the Securities Act (the “Shelf Registration Statement”). Regency shall use its reasonable best

efforts to file the Shelf Registration Statement within 45 days of any such request and cause it to be effective as soon as reasonably practicable thereafter (the “Shelf Registration”); provided, however, that the Partnership shall not be required to effect more than three registrations 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 Regency; provided, however, that if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Shelf Registration Statement and the Managing Underwriter at any time shall notify ETE in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, Regency shall use its reasonable best efforts to include such information in such a prospectus supplement. Regency 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 have been distributed in the manner set forth and as contemplated in the Shelf Registration Statement or there are no longer any Registrable Securities outstanding (the “Effectiveness Period”). The Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form 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. If Regency determines in good faith that the requested registration would be materially detrimental to Regency because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving Regency, (y) require premature disclosure of material information that Regency has a bona fide business purpose for preserving as confidential or (z) render Regency unable to comply with requirements under applicable securities laws, then Regency shall have the right to postpone such requested registration for a period of not more than three months after receipt of ETE’s request, such right pursuant to this Section 2.01(b) not to be utilized more than twice in any twelve-month period.

          (b) Delay Rights. Notwithstanding anything to the contrary contained herein, Regency may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if Regency (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 disclosure of which at such time, in the good faith judgment of Regency would materially adversely affect Regency. Upon disclosure of such information or the termination of the condition described above, Regency shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

     Section 2.02 Underwritten Offering. In the event that the Selling Holders holding a majority of the Common Units covered by this Agreement elect to dispose of Registrable

Securities under the Shelf Registration Statement pursuant to an Underwritten Offering, Regency shall enter into an underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.07, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the registration and disposition of the Registrable Securities. In connection with any Underwritten Offering under this Agreement, Regency shall be entitled to select the Managing Underwriter or Underwriters, subject to the consent of ETE not to be unreasonably withheld. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Regency to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Regency other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Regency and the Managing Underwriter; provided, however, that such withdrawal must be made up to and including the time of pricing of such offering to be effective. No such withdrawal or abandonment shall affect Regency’s obligation to pay Registration Expenses.

     Section 2.03 Registration Procedures. In connection with its obligations contained in Section 2.01, Regency 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), 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 or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request, provided that neither Regency nor its general partner 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 and each underwriter, 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 and each underwriter, 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 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 Regency 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, Regency 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) in the case of an Underwritten Offering, furnish upon request and addressed to the underwriters and to the Selling Holders, (i) an opinion of counsel for Regency, dated the effective date of the closing under the underwriting agreement, and (ii) a “comfort letter”, dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified Regency’s financial statements included or incorporated by reference into the applicable

registration statement, and each of the opinion and the “comfort letter” shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) and as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities, and such other matters as such underwriters may reasonably request;

          (h) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

          (i) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Regency personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that Regency need not disclose any information to any such representative unless and until such representative has entered into a confidentiality agreement with Regency;

          (j) 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 Regency are then listed;

          (k) use its reasonable best efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Regency to enable the Selling Holders to consummate the disposition of such Registrable Securities;

          (l) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement; and

          (m) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, including participation in “roadshows,” as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities.

     Each Selling Holder, upon receipt of notice from Regency of the happening of any event of the kind described in subsection (e) of this Section 2.03, 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 2.03 or until it is advised in writing by Regency 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 Regency, such Selling Holder will, or will request the managing underwriter or underwriters, if any, to deliver to Regency (at Regency’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 2.04 Cooperation by Holders. Regency shall have no obligation to include in the Shelf Registration Statement units of a Holder who has failed to timely furnish such information which, in the opinion of counsel to Regency, 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.

     Section 2.05 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the lock-up period contained in a prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, provided that (i) Regency gives written notice to such Holder of the date of the commencement and termination of such period with respect to any such Underwritten Offering and (ii) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on Regency or on the officers or directors or any other unitholder of Regency on whom a restriction is imposed.

     Section 2.06 Expenses.

          (a) Certain Definitions. “Registration Expenses” means all expenses incident to Regency’s performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for Regency, including the expenses of any special audits or “comfort letters” required by or incident to such performance and compliance. Except as otherwise provided in Section 2.07 hereof, Regency shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, Regency shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions allocable to the sale of the Registrable Securities.

          (b) Expenses. Regency will pay all Registration Expenses in connection with any Shelf Registration Statement filed pursuant to Section 2.01(a) of this Agreement, whether or not the Shelf Registration Statement becomes effective or any sale is made pursuant to the Shelf Registration Statement. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

     Section 2.07 Indemnification.

          (a) By Regency. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Regency will indemnify and hold harmless each Selling Holder thereunder, its directors and officers and each underwriter pursuant to the

applicable underwriting agreement with such underwriter and each Person, if any, who controls such Selling Holder or underwriter 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 underwriter 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, each such underwriter 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 Regency 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, such underwriter 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 jointly to indemnify and hold harmless Regency, its directors and officers, and each Person, if any, who controls Regency within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from Regency 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 (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

          (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.07. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.07 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.

          (d) Contribution. If the indemnification provided for in this Section 2.07 is held by a court or government agency of competent jurisdiction to be unavailable to Regency 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 Regency on the one hand and such Selling Holder on the other hand, in such proportion as is appropriate to reflect the relative fault of Regency 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 (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of Regency 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.

          (e) Other Indemnification. The provisions of this Section 2.07 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 2.08 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, Regency agrees to use its reasonable best efforts to:

          (a) Make and keep public information regarding Regency available, as those terms are understood and defined in Rule 144 of 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 Regency 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 Regency, 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 2.09 Transfer or Assignment of Registration Rights. The rights to cause Regency to include Registrable Securities in a Shelf Registration Statement may be transferred or assigned by ETE to one or more transferee(s) or assignee(s) of such Registrable Securities, provided that (a) such transferee or assignee receives at least 20% of the Common Units covered by this Agreement, (b) Regency 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 ETE under this Agreement.

     Section 2.10 Information by Holder. Any Holder or Holders of Registrable Securities included in any registration statement shall promptly furnish to Regency such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as Regency may reasonably request and as shall be required in connection with any registration, qualification or compliance referred to herein.
