ARTICLE II.

REGISTRATION RIGHTS

Section 2.01 Demand Registration.

(a) Demand Registration. At any time following the last day of the Initial Restricted Period (“Initial Restriction Expiration Date”), any Holder or Holders holding an aggregate of not less than 50% of the then outstanding Registrable Securities (“Initial Holders”) may request, by written notice (a “Demand”) to ETE, specifying the number of Registrable Securities desired to be sold (which shall not be less than 10% of the Registrable Securities, and which may not exceed the limits set forth in Section 3.01 during the Final Restricted Period), that ETE prepare and file a registration statement under the Securities Act (“Demand Registration Statement”) to permit the public resale of Registrable Securities either (a) in an Underwritten Offering or (b) from time to time as permitted by Rule 415 under the Securities Act (either, a “Demand Registration”). Promptly upon receipt of a Demand, ETE shall give written notice thereof to all other Holders. All such Holders who notify ETE in writing within fifteen (15) days after the date of such notice that they desire to include Registrable Securities in the Demand Registration Statement shall be permitted to do so. ETE shall use its commercially reasonable efforts to cause a Demand Registration Statement to become effective no later than 180 days after the date of the Demand. A Demand 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 ETE; provided, however, that if a prospectus or a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Demand Registration Statement and the Managing Underwriter selected by the Selling Holders 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 or prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, ETE shall use its commercially

4

reasonable efforts to include such information in such a prospectus or prospectus supplement. In the case of a shelf registration, ETE will cause a Demand 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 Demand Registration Statement have been distributed in the manner set forth and as contemplated in the Demand Registration Statement or there are no longer any Registrable Securities outstanding covered by such Demand Registration Statement (the “Effectiveness Period”). The Demand 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 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. As soon as practicable following the date a Demand Registration Statement becomes effective, but in any event within two Business Days after such date, ETE shall provide the Selling Holders with written notice thereof. ETE is obligated to effect only three (3) Demand Registrations pursuant to this Section 2.01.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, ETE may, upon written notice to any Selling Holder whose Registrable Securities are included in a Demand Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Demand Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Demand Registration Statement other than the closing of sales already committed for prior to receipt of such notice to suspend) if ETE (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 Demand 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 ETE, would materially adversely affect ETE; provided, however, that in no event shall the Selling Holders be suspended for a period exceeding an aggregate of 90 days (exclusive of days covered by any lock-up agreement executed by a Holder in connection with any Underwritten Offering by ETE or the Holders) in any 365-day period. Upon disclosure of such information or the termination of the condition described above, ETE shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Demand 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 Piggyback Registration.

(a) Participation. If ETE at any time proposes to file a registration statement or a prospectus supplement to an effective registration statement with respect to an Underwritten Offering of Common Units for its own account or to register any Common Units for its own account for sale to the public in an Underwritten Offering other than (x) a registration relating solely to employee benefit plans, (y) a registration relating solely to a Rule 145 transaction, or (z) a registration on any registration form which does not permit secondary sales or does not include substantially the same information as

5

would be required to be included in a registration statement covering the sale of Registrable Securities, then, as soon as practicable following the engagement of counsel to ETE to prepare the documents to be used in connection with an Underwritten Offering, ETE shall give notice of such proposed Underwritten Offering to the Holders and such notice shall offer the Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities as each such Holder may request in writing (a “Piggyback Registration”); provided, however, that ETE shall not be required to offer such opportunity to Holders if ETE has been advised by a Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have a material adverse effect on the price, timing or distribution of the Common Units. Subject to the preceding sentence and subject to Section 2.02(b), ETE shall include in such Underwritten Offering all such Registrable Securities (“Included Registrable Securities”) with respect to which ETE has received requests within ten days after ETE’s notice has been delivered in accordance with Section 7.01. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Piggyback Registration. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, ETE shall determine for any reason not to undertake or to delay such Underwritten Offering, ETE may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such offering by giving written notice to ETE of such withdrawal up to and including the time of pricing of such offering. Notwithstanding the foregoing, any Holder may deliver written notice to ETE requesting that such Holder not receive notice from ETE of any proposed Underwritten Offering; provided, that such Holder may later revoke any such notice.

(b) Priority of Piggyback Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of Common Units included in a Piggyback Registration advises ETE that the total amount of Common Units which the Selling Holders and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have a material adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises ETE can be sold without having such material adverse effect, with such number to be allocated pro rata among the Selling Holders who have requested participation in the Piggyback Registration (based, for each such Selling Holder, on the percentage derived by dividing (A) the number of Registrable Securities proposed to be sold by such Selling Holder in such offering; by (B) the aggregate number of Common Units proposed to be sold by the Selling Holders and any other Persons with registration rights that are pari passu with the rights of the Holders

6

participating in the Piggyback Registration to be included in such offering). If there are to be any Included Registrable Securities in the proposed Underwritten Offering of Common Units, then the Selling Holders representing a majority of the Registrable Securities to be sold in the Underwritten Offering shall be entitled to approve one Managing Underwriter with respect to the Registrable Securities to be sold in that Underwritten Offering.

(c) Termination of Piggyback Registration Rights. The Piggyback Registration rights granted pursuant to this Section 2.02 shall terminate two years following the Restriction Expiration Date.

Section 2.03 Underwritten Offering. In the event that a Selling Holder elects to dispose of Registrable Securities under a Demand Registration Statement pursuant to an Underwritten Offering, ETE shall enter into an underwriting agreement in customary form with the Managing Underwriter, 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 a 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, a majority of the Selling Holders shall be entitled to select the Managing Underwriter with respect to the Registrable Securities to be sold in that Underwritten Offering. In connection with an Underwritten Offering under Section 2.01 or 2.02 hereof, each Selling Holder and ETE shall be obligated to enter into an underwriting agreement which contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities, lock-up agreements 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, ETE 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 ETE or the underwriters 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 ETE and a Managing Underwriter; provided, however, that such withdrawal must be made at or prior to the time of pricing of such offering to be effective. No such withdrawal or abandonment shall affect ETE’s obligation to pay Registration Expenses.

Section 2.04 Registration Procedures. In connection with its obligations contained in Sections 2.01 and 2.02, ETE will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to the Demand Registration Statement and the prospectus used in connection therewith as may be necessary to keep a Demand Registration Statement that is a shelf registration

(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 any registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such registration statement contemplated by this Agreement, 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 any registration statement contemplated by this Agreement or any prospectus or prospectus supplement thereto;

registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by ETE 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, ETE 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;

(h) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement 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 ETE personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that ETE need not disclose any information to any

9

such representative unless and until such representative has entered into a confidentiality agreement with ETE;

(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 ETE are then listed;

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

Section 2.07 Indemnification.

(a) By ETE. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, ETE 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 of Registrable Securities thereunder 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, director, officer, 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 any registration statement contemplated by this Agreement, 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 ETE 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 any registration statement contemplated by this Agreement or any prospectus contained therein or any amendment or supplement thereof,

11

as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer, underwriter 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 ETE, its directors and officers, and each Person, if any, who controls ETE within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from ETE to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in any registration statement contemplated by this Agreement 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. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.07 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 such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against an indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the 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.

12

(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 ETE or any Selling Holder 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 ETE on the one hand and such Selling Holder on the other, in such proportion as is appropriate to reflect the relative fault of ETE 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 ETE on the one hand and each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation 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, ETE agrees to use its commercially reasonable efforts to:

(a) Make and keep public information regarding ETE 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 ETE 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

13

ETE, 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 ETE to register Registrable Securities granted to the Investor by ETE under this Article II may be transferred or assigned by the Investor to one or more transferee(s) or assignee(s) of such Registrable Securities that is an Affiliate of Investor, provided that (a) ETE 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, (b) each such transferee agrees to be bound by the terms of this Agreement, and (c) such transferee would own Registrable Securities at the time of such transfer that have a market value of not less than $25 million.

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

Section 2.11 Limitation on Subsequent Registration Rights. From and after the date hereof until the termination of the Investor’s piggyback registration rights pursuant to Section 2.02(c) hereof, ETE shall not, without the prior written consent of the Holders of a majority of the then outstanding Registrable Securities, enter into any agreement with any current or future holder of any securities of ETE that would allow such current or future holder to require ETE to include securities in any registration statement filed by ETE on a basis that would give such holder priority in any way over the piggyback rights granted to the Investor under Section 2.02 hereof.
