ARTICLE II

SALE AND PURCHASE

     Section 2.01 Sale and Purchase.

     (a) Sale and Purchase. Subject to the terms and conditions of this Agreement,
at the Closing, the Partnership hereby agrees to issue and sell to each Purchaser, and each
Purchaser hereby agrees, severally and not jointly, to purchase from the Partnership, the
number of Restricted Units determined pursuant to paragraph (b) below of this
Section 2.01, and each Purchaser agrees to pay the Partnership the Unit Purchase
Price for each Restricted Unit, in each case, as set forth in paragraph (c) below of
this Section 2.01. The obligation of each Purchaser under this Agreement is
independent of the obligation of each other Purchaser, and the failure or waiver of
performance with respect to any Purchaser does not excuse performance by any other
Purchaser.

     (b) Units. The number of Restricted Units to be issued and sold to each
Purchaser shall be the number of Restricted Units listed under the name of such Purchaser on
the attached signature pages.

     (c) Consideration. The amount per Restricted Unit each Purchaser will pay to
the Partnership to purchase the Restricted Units (the “Unit Purchase Price”) shall
be $17.182.

     Section 2.02 Closing. Subject to the terms and conditions of this Agreement, the
execution and delivery of the Basic Documents (other than this Agreement), delivery of certificates
representing the Restricted Units and execution and delivery of all other instruments, agreements,
and other documents required (which certificates representing the Restricted Units may be delivered
within seven (7) Business Days of the Closing Date) by this Agreement (the “Closing”) shall
take place on September 30, 2008, or such other date as shall be agreeable to the Parties (the
“Closing Date”). The Closing shall take place at the offices of Andrews Kurth LLP, 600
Travis, Suite 4200, Houston, Texas 77002. At the Closing, subject to the terms and conditions of
this Agreement, each of the Partnership and the Purchasers shall deliver, or cause to be delivered,
the items set forth in Article VI.

     Section 2.03 Independent Nature of Purchasers’ Obligations and Rights. The respective
obligations of each Purchaser under any Basic Document are several and not joint with the
obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the
performance of the obligations of any other Purchaser under any Basic Document. The failure or
waiver of performance under any Basic Document by any Purchaser, or on its behalf, does not excuse
performance by any other Purchaser. Nothing contained herein or in any other Basic Document, and
no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as
a partnership, an association, a joint venture or any other kind of entity, or create a presumption
that the Purchasers are in any way acting in concert or as a group for purposes of Section 13(d) of
the Exchange Act with respect to such obligations or the

6

 

transactions contemplated by any Basic Document. Each Purchaser shall be entitled to
independently protect and enforce its rights, including the rights arising out of this Agreement or
out of the other Basic Documents, and it shall not be necessary for any other Purchaser to be
joined as an additional party in any proceeding for such purpose.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP

     The Partnership represents and warrants to the Purchasers, on and as of the date of this
Agreement and on and as of the Closing Date, as follows:

     Section 3.01 Existence of the Partnership and its Subsidiaries.

     (a) The Partnership: (i) is a limited partnership duly formed, validly existing and in
good standing under the Laws of the State of Delaware; (ii) has all requisite limited
partnership power and authority, and has all governmental licenses, authorizations, consents
and approvals, necessary to own, lease, use and operate its Properties and carry on its
business as its business is now being conducted as described in the SEC Documents, except
where the failure to obtain such licenses, authorizations, consents and approvals would not
reasonably be expected to have a Partnership Material Adverse Effect; and (iii) is qualified
to do business in all jurisdictions in which the nature of the business conducted by it
makes such qualifications necessary, except where failure so to qualify would not reasonably
be expected to have a Partnership Material Adverse Effect. The Partnership is not in
violation of its certificate of limited partnership or the Partnership Agreement.

     (b) The General Partner has been duly formed and is validly existing and in good
standing under the laws of the State of Delaware and has all requisite limited liability
company power and authority, and has all governmental licenses, authorizations, consents and
approvals necessary, to own, lease, use or operate its Properties and carry on its business
as now being conducted and as described in the SEC Documents, except where the failure to
obtain such licenses, authorizations, consents and approvals would not be reasonably likely
to have a Partnership Material Adverse Effect.

     Section 3.02 Restricted Units, Capitalization and Valid Issuance.

     (a) The Restricted Units shall have those rights, preferences, privileges and
restrictions governing the Units as set forth in the Partnership Agreement. A true and
correct copy of the Partnership Agreement has been filed by the Partnership with the
Commission.

     (b) As of the date of this Agreement, the issued and outstanding limited partner
interests of the Partnership consist of 57,196,211 Units, 27,727,411 Subordinated Units and
the Incentive Distribution Rights (as defined in the Partnership Agreement) and the only
issued and outstanding general partner interest is the General Partner’s 2% general partner
interest. All of the outstanding Units, Subordinated Units and Incentive Distribution
Rights have been duly authorized and validly issued in accordance with applicable Law under
the Delaware LP Act and the Partnership Agreement and are fully

7

 

paid (to the extent required under applicable Law and the Partnership Agreement) and
nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607
and 17-804 of the Delaware LP Act).

     (c) Other than the El Paso GP LTIP, the Partnership has no equity compensation plans
that contemplate the issuance of Units (or securities convertible into or exchangeable for
Units). No indebtedness having the right to vote (or convertible into or exchangeable for
securities having the right to vote) on any matters on which the Unitholders may vote is
issued or outstanding. Except (i) as have been granted pursuant to El Paso GP LTIP, (ii) as
contemplated by this Agreement, (iii) as contemplated by the Contribution Agreement or (iv)
as are contained in the Partnership Agreement, there are no outstanding or authorized (A)
options, warrants, preemptive rights, subscriptions, calls, convertible or exchangeable
securities or other rights, agreements, claims or commitments of any character obligating
the Partnership or any of its Subsidiaries to issue, transfer or sell any limited partner
interests or other equity interests in, the Partnership or securities convertible into or
exchangeable for such limited partner interests or other equity interests, (B) obligations
of the Partnership to repurchase, redeem or otherwise acquire any limited partner interests
or other equity interests of the Partnership or any of its Subsidiaries or any such
securities or agreements listed in clause (A) of this sentence or (C) voting trusts
or similar agreements to which the Partnership or any of its Subsidiaries is a party with
respect to the voting of the equity interests of the Partnership. Neither the execution of
this Agreement nor the issuance of the Units as contemplated by this Agreement gives rise to
any rights for or relating to the registration of any securities of the Partnership, other
than pursuant to the Registration Rights Agreement.

     (d) (i) All of the issued and outstanding equity interests of each of the
Partnership’s Subsidiaries are owned, directly or indirectly, by the Partnership free and
clear of any Liens (except for such restrictions as may exist under applicable Law, the
organizational documents of such Subsidiaries), and all such ownership interests have been
duly authorized, validly issued and are fully paid (to the extent required by applicable Law
and the organizational documents of such Subsidiaries) and non-assessable (except as
nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP
Act and Sections 18-607 and 18-804 of the Delaware LLC Act, as applicable, or the
organizational documents of such Subsidiaries) and (ii) except as disclosed in the
Partnership’s SEC Documents, neither the Partnership nor any of its Subsidiaries owns any
shares of capital stock or other securities of, or interest in, any other Person, or is
obligated to make any capital contribution to or other investment in any other Person other
than such Subsidiaries, CIG and SNG.

     (e) After giving effect to the transactions contemplated by the Contribution Agreement,
EPPP CIG will directly own a 40% general partnership interest in CIG and EPPP SNG will
directly own a 25% general partnership interest in SNG and all such general partnership
interests will have been duly authorized and validly issued.

     (f) The offer and sale of the Restricted Units and the limited partner interests
represented thereby have been duly authorized by the Partnership pursuant to the

8

 

Partnership Agreement and, when issued and delivered to the Purchasers against payment
therefore in accordance with the terms of this Agreement, will be validly issued, fully paid
(to the extent required by applicable Law and the Partnership Agreement) and nonassessable
(except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of
the Delaware LP Act) and will be free of any and all Liens and restrictions on transfer,
other than restrictions on transfer under the Partnership Agreement and under applicable
state and federal securities Laws and other than such Liens as are created by the
Purchasers.

     (g) The Restricted Units will be issued in compliance with all applicable rules of the
NYSE. Prior to the Closing Date, the Partnership will submit to the NYSE a Supplemental
Listing Application with respect to the Restricted Units. The Partnership’s currently
outstanding Units are quoted on the NYSE and the Partnership has not received any notice of
delisting.

     (h) None of the execution of this Agreement, the offering or sale of the Restricted
Units or the registration of the Units pursuant to the Registration Rights Agreement gives
rise to any rights for or relating to the registration of any Units or other securities of
the Partnership other than pursuant to the Registration Rights Agreement and those rights
granted to the General Partner or any of its Affiliates (as such term is defined in the
Partnership Agreement) under Section 7.12 of the Partnership Agreement.

     Section 3.03 SEC Documents. The Partnership has filed with the Commission all
reports, schedules and statements required to be filed by it under the Exchange Act since the
consummation of its initial public offering (all such documents filed on or prior to the date of
this Agreement, but specifically excluding any documents “furnished,” collectively, the “SEC
Documents”). The SEC Documents, including any Partnership audited or unaudited financial
statements and any notes thereto or schedules included therein, at the time filed (except to the
extent corrected by a subsequently filed SEC Document filed prior to the date of this Agreement)

required to be stated therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, (ii) complied as to form in all material
respects with applicable requirements of the Exchange Act and the applicable accounting
requirements and with the published rules and regulations of the Commission with respect thereto,

unaudited statements to normal, recurring and year-end audit adjustments) in all material respects

results of its operations and cash flows for the periods then ended. Ernst & Young LLP is an
independent registered public accounting firm with respect to the Partnership and has not resigned
or been dismissed as an independent registered public accountant of the Partnership as a result of
or in connection with any disagreement with the Partnership on any matter of accounting principles
or practices, financial statement disclosure or auditing scope or procedures.

the SEC Documents filed with the Commission since June 30, 2008, the Partnership and its
Subsidiaries have conducted their business in the ordinary course, consistent with past practice,

Material Adverse Effect, (ii) acquisition or disposition of any material asset by the Partnership
or any of its Subsidiaries or any contract or arrangement therefore, otherwise than for fair value
in the ordinary course of business, (iii) material change in the Partnership’s accounting
principles, practices or methods or (iv) incurrence of material indebtedness.

     Section 3.05 Litigation. Except as set forth in the SEC Documents, there is no Action
pending or, to the Knowledge of the Partnership, contemplated or threatened against the Partnership
or any of its Subsidiaries or any of their respective officers (in their capacity as such),
directors (in their capacity as such) or Properties, (a) which (individually or in the aggregate)
reasonably would be expected to have a Partnership Material Adverse Effect or which challenges the
validity of any of the Basic Documents or the right of the Partnership to enter into any of the
Basic Documents or to consummate the transactions contemplated hereby and thereby or (b) which
would reasonably be expected to adversely affect or restrict the Partnership’s ability to
consummate the transactions contemplated by the Basic Documents.

     Section 3.06 No Breach. The execution, delivery and performance by the Partnership of
the Basic Documents to which it is a party and all other agreements and instruments to be executed
and delivered by the Partnership pursuant hereto or thereto or in connection herewith and
therewith, and compliance by the Partnership with the terms and provisions hereof and thereof, do
not and will not (a) violate any provision of any Law, governmental permit, determination or award
having applicability to the Partnership or any of its Subsidiaries or any of their respective
Properties, (b) conflict with or result in a violation of any provision of the organizational
documents of the Partnership or any of its Subsidiaries, (c) require any consent, approval or
notice under or result in a violation or breach of or constitute (with or without due notice or
lapse of time or both) a default (or give rise to any right of termination, cancellation or
acceleration) under any note, bond, mortgage, license, loan or credit agreement or other
instrument, obligation or agreement to which the Partnership or any of its Subsidiaries is a party
or by which the Partnership or any of its Subsidiaries or any of their respective Properties may be
bound or (d) result in or require the creation or imposition of any Lien upon or with respect to
any of the Properties now owned or hereafter acquired by the Partnership or any of its
Subsidiaries, except in the cases of clauses (a), (c) and (d) where such violation, default,
breach, termination, cancellation, failure to receive consent or approval, or acceleration with
respect to the foregoing provisions of this Section 3.06 would not, individually or in the
aggregate, reasonably be expected to have a Partnership Material Adverse Effect.

     Section 3.07 Authority. The Partnership has all necessary limited partnership power
and authority to execute, deliver and perform its obligations under the Basic Documents to which it
is a party and to consummate the transactions contemplated thereby; the execution, delivery and
performance by the Partnership of the Basic Documents to which it is a party, and the consummation
of the transactions contemplated thereby, have been duly authorized by all necessary action on its
part; and the Basic Documents will constitute the legal, valid and binding obligations of
Partnership, enforceable in accordance with their terms, except as such enforceability may be
limited by bankruptcy, insolvency, fraudulent transfer and similar Laws

10

 

affecting creditors’ rights generally or by general principles of equity, including principles
of commercial reasonableness, fair dealing and good faith. No approval from the holders of
outstanding Units is required under the Partnership Agreement or the rules of the NYSE in
connection with the Partnership’s issuance and sale of the Restricted Units to the Purchasers.

     Section 3.08 Approvals. Except as required by the Commission in connection with the
Partnership’s obligations under the Registration Rights Agreement, no authorization, consent,
approval, waiver, license, qualification or written exemption from, nor any filing, declaration,
qualification or registration with, any Governmental Authority or any other Person is required in
connection with the execution, delivery or performance by the Partnership of any of the Basic
Documents to which it is a party or the Partnership’s issuance and sale of the Restricted Units,
except (i) as may be required under the state securities or “Blue Sky” Laws, or (ii) where the
failure to receive such authorization, consent, approval, waiver, license, qualification or written
exemption or to make such filing, declaration, qualification or registration would not,
individually or in the aggregate, reasonably be expected to have a Partnership Material Adverse
Effect.

     Section 3.09 MLP Status. The Partnership has, for each taxable year beginning on or
after the closing of its initial public offering, met the gross income requirements of Section
7704(c)(2) of the Internal Revenue Code of 1986, as amended.

company” within the meaning of the Investment Company Act of 1940, as amended.

     Section 3.11 Valid Private Placement. Assuming the accuracy of the representations
and warranties of the Purchasers contained in this Agreement, the sale and issuance of the
Restricted Units pursuant to this Agreement is exempt from the registration requirements of the
Securities Act, and neither the Partnership nor, to the Knowledge of the Partnership, any
authorized Representative acting on its behalf has taken or will take any action hereafter that
would cause the loss of such exemption.

     Section 3.12 Certain Fees. No fees or commissions are or will be payable by the
Partnership to brokers, finders, or investment bankers with respect to the sale of any of the
Restricted Units or the consummation of the transactions contemplated by this Agreement.

     Section 3.13 No Side Agreements. Except for the Registration Rights Agreement, there
are no other agreements by, among or between the Partnership or its Affiliates, on the one hand,
and any of the Purchasers or their Affiliates, on the other hand, with respect to the transactions
contemplated hereby nor promises or inducements for future transactions between or among any of
such parties.

     Section 3.14 Form S-3 Eligibility. In December 2008, the Partnership is expected to
be eligible to register the Restricted Units for resale by the Purchasers on a registration
statement on Form S-3 under the Securities Act.

     Section 3.15 Taxes. The Partnership has filed all Tax Returns required to be filed.
To the Knowledge of the Partnership, such Tax Returns are true, correct and complete in all
material respects. The Partnership has paid in full all Taxes shown to be due on such Tax Returns.
The

11

 

Partnership has not received any written notice of deficiency or assessment from any taxing
authority with respect to liabilities for any material Taxes, which have not been fully paid or
finally settled, unless being contested in good faith through appropriate proceedings and for which
adequate reserves are presented in the Partnership’s financial statements included in the SEC
Documents.

     Section 3.16 Acknowledgment Regarding Purchase of Restricted Units. The Partnership
acknowledges and agrees that (i) each of the Purchasers is participating in the transactions
contemplated by this Agreement and the other Basic Documents at the Partnership’s request and the
Partnership has concluded that such participation is in the Partnership’s best interest and is
consistent with the Partnership’s objectives and (ii) each of the Purchasers is acting solely in
the capacity of an arm’s length purchaser. The Partnership further acknowledges that no Purchaser
is acting or has acted as an advisor, agent or fiduciary of the Partnership (or in any similar
capacity) with respect to this Agreement or the other Basic Documents and any advice given by any
Purchaser or any of its respective Representatives in connection with this Agreement or the other
Basic Documents is merely incidental to the Purchasers’ purchase of the Restricted Units. The
Partnership further represents to each Purchaser that the Partnership’s decision to enter into this
Agreement has been based solely on the independent evaluation of the transactions contemplated
hereby by the Partnership and its Representatives.

     Section 3.17 Compliance with Laws. Neither the Partnership nor any of its
Subsidiaries is in violation of any Law applicable to the Partnership or its Subsidiaries, except
as would not, individually or in the aggregate, have a Partnership Material Adverse Effect. The
Partnership and its Subsidiaries possess all certificates, authorizations and permits issued by the
appropriate regulatory authorities necessary to conduct their respective businesses, except where
the failure to possess such certificates, authorizations or permits would not have, individually or
in the aggregate, a Partnership Material Adverse Effect, and neither the Partnership nor any such
Subsidiary has received any notice of proceedings relating to the revocation or modification of any
such certificate, authorization or permit, except where such potential revocation or modification
would not have, individually or in the aggregate, a Partnership Material Adverse Effect.

     Section 3.18 Insurance. The Partnership and the General Partner are insured against
such losses and risks and in such amounts as the Partnership believes in its sole discretion to be
prudent for its businesses. The Partnership does not have any reason to believe that it or the
General Partner will not be able to renew its existing insurance coverage as and when such coverage
expires or to obtain similar coverage from similar insurers as may be necessary to continue its
business.

     Section 3.19 No Integrated Offering. Neither the Partnership, nor any of its
Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any
offers or sales of any security or solicited any offers to buy any security, under circumstances
that would cause this offering of the Restricted Units to be integrated with prior offerings by the
Partnership for purposes of the Securities Act or any applicable stockholder approval provisions,
including, without limitation, under the rules and regulations of the trading market on which the
Units are currently listed or quoted.

12

 

     Section 3.20 Registration Rights. Neither the execution of this Agreement nor the
issuance of the Purchased Units as contemplated by this Agreement gives rise to any rights for or
relating to the registration of any securities of the Partnership, other than pursuant to the
Registration Rights Agreement.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF EACH PURCHASER

     Each Purchaser, severally and not jointly, represents and warrants to the Partnership with
respect to itself, on and as of the date of this Agreement and on and as of the Closing Date, as
follows:

     Section 4.01 Valid Existence. Such Purchaser (a) is duly incorporated or formed,
validly existing and in good standing under the Laws of its respective jurisdiction of
incorporation or formation, and (b) has all requisite power and authority, and has all material
governmental licenses, authorizations, consents and approvals necessary to own its Properties and
carry on its business as its business is now being conducted, except where the failure to obtain
such licenses, authorizations, consents and approvals would not reasonably be expected to have a
Purchaser Material Adverse Effect. Each such Purchaser is not in default in the performance,
observance or fulfillment of any provision of its organizational documents, except where such
default would not have or would not reasonably be likely to have a Purchaser Material Adverse
Effect.

     Section 4.02 No Breach. The execution, delivery and performance by such Purchaser of
the Basic Documents to which it is a party and all other agreements and instruments to be executed
and delivered by such Purchaser pursuant hereto or thereto or in connection herewith or therewith,
compliance by such Purchaser with the terms and provisions hereof and thereof, and the purchase of
the Restricted Units by such Purchaser do not and will not (a) violate any provision of any Law,
governmental permit, determination or award having applicability to such Purchaser or any of its
Properties, (b) conflict with or result in a violation of any provision of the organizational
documents of such Purchaser or (c) require any consent (other than standard internal consents),
approval or notice under or result in a violation or breach of or constitute (with or without due
notice or lapse of time or both) a default (or give rise to any right of termination, cancellation
or acceleration) under any note, bond, mortgage, license, loan or credit agreement or other
instrument or agreement to which such Purchaser is a party or by which such Purchaser or any of its
Properties may be bound, except in the case of clauses (a) and (c), where such violation, default,
breach, termination, cancellation, failure to receive consent or approval, or acceleration with
respect to the foregoing provisions of this Section 4.02 would not, individually or in the
aggregate, reasonably be expected to have a Purchaser Material Adverse Effect.

     Section 4.03 Authority. The Purchaser has all necessary corporate, limited liability
company or partnership power and authority to execute, deliver and perform its obligations under
the Basic Documents to which it is a party and to consummate the transactions contemplated thereby;
the execution, delivery and performance by the Purchaser of the Basic Documents to which it is a
party, and the consummation of the transactions contemplated thereby, have been duly authorized by
all necessary action on its part; and the Basic Documents will constitute the

13

 

legal, valid and binding obligations of Purchaser, enforceable in accordance with their terms,
except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and
similar Laws affecting creditors’ rights generally or by general principles of equity, including
principles of commercial reasonableness, fair dealing and good faith.

     Section 4.04 Investment. The Restricted Units are being acquired for such Purchaser’s
own account, the account of its Affiliates, or the accounts of clients for whom such Purchaser
exercises discretionary investment authority (all of whom the Purchaser hereby represents and
warrants are “accredited investors” within the meaning of Rule 501(a) of Regulation D or “qualified
institutional buyer” within the meaning of Rule 144A promulgated by the Commission pursuant to the
Securities Act), not as a nominee or agent, and with no present intention of distributing the
Restricted Units or any part thereof, and that such Purchaser has no present intention of selling
or granting any participation in or otherwise distributing the same in any transaction in violation
of the securities Laws of the United States of America or any state, without prejudice, however,
subject to such Purchaser’s right at all times (subject to such Purchaser’s agreement contained in
Section 5.02) to sell or otherwise dispose of all or any part of the Restricted Units under
a registration statement under the Securities Act and applicable state securities Laws or under an
exemption from such registration available thereunder (including, without limitation, if available,
Rule 144 promulgated thereunder). If such Purchaser should in the future decide to dispose of any
of the Restricted Units, such Purchaser understands and agrees (a) that it may do so only (i) in
compliance with the Securities Act and applicable state securities law, as then in effect, or
pursuant to an exemption therefrom (including Rule 144 under the Securities Act) or (ii) in the
manner contemplated by any registration statement pursuant to which such securities are being
offered, and (b) that stop-transfer instructions to that effect will be in effect with respect to
such securities. Notwithstanding the foregoing, any Purchaser may at any time enter into one or
more total return swaps with respect to such Purchaser’s Restricted Units with a third party or
transfer Restricted Units to an Affiliate of such Purchaser provided that any such transaction is
exempt from registration under the Securities Act.

     Section 4.05 Nature of Purchaser. Such Purchaser represents and warrants to, and
covenants and agrees with, the Partnership that, (a) it is an “accredited investor” within the
meaning of Rule 501(a) of Regulation D or a “qualified institutional buyer” under Rule 144A as
promulgated by the Commission pursuant to the Securities Act and (b) by reason of its business and
financial experience it has such knowledge, sophistication and experience in business and financial
matters so as to be capable of evaluating the merits and risks of the prospective investment in the
Restricted Units, is able to bear the economic risk of such investment and, at the present time,
would be able to afford a complete loss of such investment.

     Section 4.06 Receipt of Information; Authorization. Such Purchaser acknowledges that
it (a) has access to the SEC Documents with the Commission and (b) has been provided a reasonable
opportunity to ask questions of and receive answers from Representatives of the Partnership
regarding such matters.

     Section 4.07 Restricted Securities. Such Purchaser understands that the Restricted
Units it is purchasing are characterized as “restricted securities” under the federal securities
Laws inasmuch as they are being acquired from the Partnership in a transaction not involving a

14

 

public offering and that under such Laws and applicable regulations such securities may be
resold without registration under the Securities Act only in certain limited circumstances. In
this connection, such Purchaser represents that it is knowledgeable with respect to Rule 144 of the
Commission promulgated under the Securities Act.

     Section 4.08 Certain Fees. No fees or commissions will be payable by such Purchaser
to brokers, finders, or investment bankers with respect to the sale of any of the Restricted Units
or the consummation of the transactions contemplated by this Agreement.

     Section 4.09 Legend. It is understood that the certificates evidencing the Restricted
Units will bear the following legend:

“These securities have not been registered under the Securities Act
of 1933, as amended (the “Securities Act”), or the securities laws
of any state or other jurisdiction. These securities may not be
sold or offered for sale except pursuant to an effective
registration statement under the Securities Act or pursuant to an
exemption from registration thereunder, in each case in accordance
with all applicable securities laws of the states or other
jurisdictions, and in the case of a transaction exempt from
registration, such securities may only be transferred if the
transfer agent for such securities has received documentation
satisfactory to it that such transaction does not require
registration under the Securities Act.”

     Section 4.10 No Substantial Security Holders. Such Purchaser represents and warrants
to, and covenants and agrees with, the Partnership that, on the date hereof and as of the date of
Closing (before giving effect to the purchase of Restricted Units pursuant to this Agreement), such
Purchaser and its Affiliates (a) hold beneficial ownership of less than five percent of the Units
of the Partnership outstanding on the date hereof and (b) hold beneficial ownership of less than
five percent of the outstanding voting power of the Partnership.

     Section 4.11 No Side Agreements. Other than this Agreement, there are no agreements
by, among or between such Purchaser and any of its Affiliates, on the one hand, and the (i) other
Purchasers or their Affiliates, or (ii) the Partnership and its Affiliates, on the other hand, with
respect to the transactions contemplated hereby nor promises or inducements for future transactions
between or among any of such parties.

     Section 4.12 Short Selling. Such Purchaser has not engaged in any Short Sales
involving Units owned by it between the time it first began discussions with the Partnership about
the transaction contemplated by this Agreement and the date hereof (it being understood that the
entering into of a total return swap should not be considered a short sale).

     Section 4.13 Record Date; Distributions. The Board of directors of the General
Partner approved a cash distribution attributable to the second quarter of 2008, which was paid on
August 14, 2008 to Unitholders of record at the close of business on July 31, 2008. Each

15

 

Purchaser acknowledges that it will not be entitled to any distribution or other dividend from
the Partnership attributable to the second quarter of 2008 with respect to the Restricted Units.

ARTICLE V

COVENANTS

     Section 5.01 Issuer Lock-Up/Subsequent Issuances of Units. Without the written
consent of the holders of a majority of the Restricted Units, from the signing date of the
Agreement until the Lock-Up Date, the Partnership shall not grant, issue or sell any Units or other
equity or voting securities of the Partnership or any securities convertible thereinto or
exchangeable therefor, or take any other action that may result in the issuance of any of the
foregoing, other than (i) the issuance of options or Units under the El Paso GP LTIP, or the
issuance of Units upon the exercise of awards issued under the El Paso GP LTIP, (ii) the issuance
of the Units pursuant to the Contribution Agreement, (iii) the issuance or sale of Units at a price
no less than 110% of the Unit Purchase Price (including, and not net of, any underwriting discounts
and commissions or placement fees), and (iv) Units issued as consideration for, or to finance the
acquisition of, assets or equity. Notwithstanding the foregoing, the Partnership shall not sell,
offer for sale or solicit offers to buy any security (as defined in the Securities Act) that would
be integrated with the sale of the Restricted Units in a manner that would require the registration
under the Securities Act of the sale of the Restricted Units to the Purchasers.

     Section 5.02 Purchaser Lock-Ups. Without the prior written consent of the
Partnership, each Purchaser agrees that neither such Purchaser nor any of its Affiliates will
offer, sell, pledge or otherwise transfer or dispose of any of its Restricted Units prior to the
Lock-Up Date; provided, however, that any Purchaser may, (i) subject Section 8.04(c), enter
into one or more total return swaps or similar transactions at any time with respect to the
Restricted Units purchased by such Purchaser provided that such transaction is exempt from
registration under the Securities Act and (ii) transfer its Restricted Units to an Affiliate of
such Purchaser or to any other Purchaser or an Affiliate of such other Purchaser, provided that any
such Affiliate transferee agrees to the restrictions set forth in this Section 5.02.

     Section 5.03 Taking of Necessary Action. Each of the Parties hereto shall use its
commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do
or cause to be done all things necessary, proper or advisable under applicable Law and regulations
to consummate and make effective the transactions contemplated by this Agreement. Without limiting
the foregoing, the Partnership and each Purchaser shall use its commercially reasonable efforts to
make all filings and obtain all consents of Governmental Authorities that may be necessary or, in
the reasonable opinion of the other Parties, as the case may be, advisable for the consummation of
the transactions contemplated by the Basic Documents.

     Section 5.04 Disclosure; Public Filings. The Partnership may, without prior written
consent or notice, (i) file this Agreement as an exhibit to an Exchange Act report and (ii)
disclose information with respect to any Purchaser solely to the extent required by applicable Law
or the rules and regulations of the Commission or any regulatory agency, the NYSE or other exchange
on which securities of the Partnership are listed or traded.

16

 

     Section 5.05 Other Actions. The Partnership shall file prior to the Closing a
supplemental listing application with the NYSE to list the Restricted Units.

     Section 5.06 Use of Proceeds. The Partnership shall use the collective proceeds from
the sale of the Restricted Units to partially fund the acquisition of an incremental interest of 15
percent of Southern Natural Gas Company and 30 percent of Colorado Interstate Gas Company from El
Paso Corporation and its Affiliates. If the transactions contemplated by Contribution Agreement
are not closed concurrently with the Closing or within two Business Days thereafter, the
Partnership shall return the Commitment Purchase Amount paid to the Partnership to the applicable
Purchasers within two Business Days of receipt thereof and the Purchaser shall promptly return all
Restricted Units to the Partnership.

     Section 5.07 Partnership Fees. The Partnership agrees that it will indemnify and hold
harmless each of the Purchasers from and against any and all claims, demands, or liabilities for
broker’s, finder’s, placement, or other similar fees or commissions incurred by the Partnership or
alleged to have been incurred by the Partnership in connection with the sale of Restricted Units or
the consummation of the transactions contemplated by this Agreement.

     Section 5.08 Purchaser Fees. Each Purchaser agrees, severally and not jointly with
the other Purchasers, that it will indemnify and hold harmless the Partnership from and against any
and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or
commissions incurred by such Purchaser or alleged to have been incurred by such Purchaser in
connection with the purchase of Restricted Units or the consummation of the transactions
contemplated by this Agreement.

     Section 5.09 Certain Special Allocations of Book and Taxable Income. To the extent
that the Unit Purchase Price differs from the trading price of the Units on the NYSE as of the
Closing Date (the “Private Placement Value”), the General Partner intends to specially
allocate Partnership items of book and taxable income, gain, loss or deduction to the Purchasers so
that their capital accounts in their Restricted Units are equal, on a per-Unit basis, with the
capital accounts of the other holders of Units (and thus to assure fungibility of all Units). Such
special allocation will occur upon the earlier to occur of any taxable period of the Partnership
ending upon, or after, (a) a book-up event or book-down event in accordance with Treasury
Regulation Section 1.704-1(b)(2)(iv)(f) or a sale of all or substantially all of the assets of the
Partnership occurring after the date of the issuance of the Restricted Units, or (b) the transfer
of the Restricted Units to a Person that is not an Affiliate of the Purchaser, in which case, such
allocation shall be made only with respect to the Restricted Units so transferred. A Purchaser
holding a Restricted Unit shall be required to provide notice to the General Partner of a transfer
of a Restricted Unit to a Person who is not an Affiliate of the Purchaser no later than the last
Business Day of the calendar year during which such transfer occurred, unless by virtue of the
application of clause (a) above, the General Partner has determined that the capital accounts of
Units transferred are equal, on a per-Unit basis, with the capital accounts of the other holders of
Units. The initial capital account balance in respect of each Restricted Unit shall be the Private
Placement Value for such Restricted Unit. To provide Purchasers of the Restricted Units with a net
capital account in the Restricted Units on the date of purchase equal to the Unit Purchase Price
paid by those Purchasers for the Restricted Units, immediately following the creation of a capital
account balance in respect of each Restricted Unit, each holder acquiring a Restricted

17

 

Unit at original issuance shall be deemed to have (x) received a cash distribution in respect
of each Restricted Unit in an amount equal to any excess of the Private Placement Value over the
Unit Purchase Price of the Restricted Unit or (y) made a cash contribution in respect of each
Restricted Unit in an amount equal to any excess of the Unit Purchase Price over the Private
Placement Value of the Restricted Unit.

     Section 5.10 Non-Disclosure; Interim Public Filings. The Partnership shall, on or
before 8:30 a.m., New York time, on the first Business Day following execution of this Agreement,
issue a press release disclosing all material terms of the transactions contemplated hereby.
Before 8:30 a.m., New York time, on the fourth Business Day following the Closing Date, the
Partnership shall file a Current Report on Form 8-K with the Commission (the “8-K Filing”)
describing the terms of the transactions contemplated by this Agreement and the other Basic
Documents and including as exhibits to such Current Report on Form 8-K this Agreement and the other
Basic Documents, in the form required by the Exchange Act.

     Section 5.11 Acknowledgement and Agreement Regarding Short Sales. Each Purchaser
understands and acknowledges, severally and not jointly with any other Purchaser, that the
Commission currently takes the position that coverage of short sales of securities “against the
box” prior to the effective date of a registration statement or prior to being eligible to sell in
reliance upon the exemption provided in Rule 144 of the Securities Act is a violation of Section 5
of the Securities Act. Each Purchaser agrees, severally and not jointly, that it will not engage
in any Short Sales that result in the disposition of the Restricted Units acquired hereunder by the
Purchaser until such time as the Shelf Registration Statement (as defined in the Registration
Rights Agreement) is declared effective (it being understood that the entering into of a total
return swap should not be considered a Short Sale of Units). No Purchaser makes any
representation, warranty or covenant hereby that it will not engage in Short Sales in the
securities of the Partnership otherwise owned by such Purchaser or borrowed from a broker after the
date the press release contemplated by this Agreement is issued by the Partnership.

ARTICLE VI

ARTICLE VII

INDEMNIFICATION, COSTS AND EXPENSES

     Section 7.01 Indemnification by the Partnership. The Partnership agrees to indemnify
each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from,
and hold each of them harmless against, any and all losses, actions, suits, proceedings (including
any investigations, litigation or inquiries), demands and causes of action, and, in connection
therewith, and promptly on demand, pay and reimburse each of them for all costs, losses,
liabilities, damages, or expenses of any kind or nature whatsoever, including the reasonable fees
and disbursements of counsel and all other reasonable expenses incurred in connection with
investigating, defending or preparing to defend any such matter that may be incurred by them or
asserted against or involve any of them as a result of, arising out of, or in any way related to
the breach of any of the representations, warranties or covenants of the Partnership contained
herein; provided that such claim for indemnification relating to a breach of a representation or
warranty is made prior to the expiration of such representation or warranty; and provided further,
that no Purchaser Related Party shall be entitled to recover special, consequential (including lost
profits) or punitive damages. Notwithstanding anything to the contrary, consequential damages
shall not be deemed to include diminution in value of the Restricted Units, which is specifically
included in damages covered by Purchaser Related Parties’ indemnification.

     Section 7.02 Indemnification by Purchasers. Each Purchaser agrees, severally and not
jointly, to indemnify the Partnership, the General Partner and their respective Representatives
(collectively, “Partnership Related Parties”) from, and hold each of them harmless against,
any and all losses, actions, suits, proceedings (including any investigations, litigation, or
inquiries), demands and causes of action and, in connection therewith, and promptly upon demand,
pay and reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind
or nature whatsoever, including, without limitation, the reasonable fees and disbursements of
counsel and all other reasonable expenses incurred in connection with investigating, defending or
preparing to defend any such matter that may be incurred by them or asserted against or involve

21

 

any of them as a result of, arising out of, or in any way related to the breach of any of the
representations, warranties or covenants of such Purchaser contained herein; provided that such
claim for indemnification relating to a breach of a representation or warranty is made prior to the
expiration of such representation or warranty; and provided further, that no Partnership Related
Party shall be entitled to recover special, consequential (including lost profits) or punitive
damages.

     Section 7.03 Indemnification Procedure. Promptly after any Partnership Related Party
or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of
any indemnifiable claim hereunder, or the commencement of any action or proceeding by a third
party, which the Indemnified Party believes in good faith is an indemnifiable claim under this
Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying
Party”) written notice of such claim or the commencement of such action or proceeding, but
failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any
liability it may have to such Indemnified Party hereunder except to the extent that the
Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and
the basis of such claim to the extent then known.

     The Indemnifying Party shall have the right to defend and settle, at its own expense and by
its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as
long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying
Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its
intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its
counsel in all commercially reasonable respects in the defense thereof and the settlement thereof.
Such cooperation shall include furnishing the Indemnifying Party with any books, records and other
information reasonably requested by the Indemnifying Party and in the Indemnified Party’s
possession or control. Such cooperation of the Indemnified Party shall be at the cost of the
Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for so long as the
Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for
any additional legal expenses incurred by the Indemnified Party in connection with any defense or
settlement of such asserted liability; provided, however, that the Indemnified Party shall be
entitled (i) at its expense, to participate in the defense of such asserted liability and the
negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume
the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) 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 in addition 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 expenses and fees of such separate counsel and other expenses
related to such participation to be reimbursed by the Indemnifying Party as incurred.
Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any
indemnified claim without the consent of the Indemnified Party, unless the settlement thereof
imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and
includes a complete release from liability of, the Indemnified Party.

and agreements are references to such instruments, documents, contracts, and agreements as the same
may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified.
The word “including” shall mean “including but not limited to.” Whenever any Party has an

expense of such Party unless otherwise specified therein. Whenever any determination, consent or
approval is to be made or given by a Purchaser under the Basic Documents, such action shall be in
such Purchaser’s sole discretion unless otherwise specified therein. If any provision in the Basic
Documents is held to be illegal, invalid, not binding, or unenforceable, such provision shall be
fully severable and the Basic Documents shall be construed and enforced as if such illegal,
invalid, not binding, or unenforceable provision had never comprised a part of the Basic Documents,
and the remaining provisions shall remain in full force and effect. The Basic Documents have been
reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be
construed against the drafter.

     Section 8.02 Survival of Provisions. The representations and warranties set forth in

4.10 and 4.13 of this Agreement shall survive the execution and delivery of this
Agreement indefinitely, and the other representations and warranties set forth in this Agreement
shall survive for a period of twelve (12) months following the Closing Date regardless of any

indemnification obligations of the Partnership and the Purchasers pursuant to this Agreement and
the provisions of Article VII shall remain operative and in full force and effect unless
such obligations are expressly terminated in a writing by the Parties, regardless of any purported
general termination of this Agreement.

     Section 8.03 No Waiver; Modifications in Writing.

     (a) Delay. No failure or delay on the part of any Party in exercising any
right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power, or remedy preclude any other or further exercise
thereof or the exercise of any right, power, or remedy. The remedies provided for herein are
cumulative and are not exclusive of any remedies that may be available to a Party at Law or
in equity or otherwise.

     (b) Specific Waiver. Except as otherwise provided herein, no amendment,
waiver, consent, modification, or termination of any provision of this Agreement or any
other Basic Document shall be effective unless signed by each of Parties or each of the
original signatories thereto affected by such amendment, waiver, consent, modification, or
termination. Any amendment, supplement or modification of or to any provision of

23

 

this Agreement or any other Basic Document, any waiver of any provision of this
Agreement or any other Basic Document, and any consent to any departure by the Partnership
from the terms of any provision of this Agreement or any other Basic Document shall be
effective only in the specific instance and for the specific purpose for which made or
given. Except where notice is specifically required by this Agreement, no notice to or
demand on the Partnership in any case shall entitle the Partnership to any other or further
notice or demand in similar or other circumstances.

     Section 8.04 Binding Effect; Assignment.

     (a) Binding Effect. This Agreement shall be binding upon the Partnership, each
Purchaser, and their respective successors and permitted assigns. Except as expressly
provided in this Agreement, this Agreement shall not be construed so as to confer any right
or benefit upon any Person other than the Parties to this Agreement and as provided in
Article VII, and their respective successors and permitted assigns.

     (b) Assignment of Restricted Units. All or any portion of a Purchaser’s
Restricted Units purchased pursuant to this Agreement may be sold, assigned or pledged by
such Purchaser, subject to compliance with applicable securities Laws, Section 4.04
and Section 5.02 and the Registration Rights Agreement.

     (c) Assignment of Rights. Each Purchaser under this Agreement may assign all or
any portion of its rights hereunder without the consent of the Partnership to (i) any
Affiliate of such Purchaser or (ii) in connection with a total return swap or similar
transaction with respect to the Restricted Units purchased by such Purchaser; provided, in
each case, the assignee shall be deemed to be a Purchaser hereunder with respect to such
assigned rights and shall agree to be bound by the provisions of this Agreement. Except as
expressly permitted by this Section 8.04(c), such rights may not otherwise be
transferred except with the prior written consent of the Partnership (which consent shall
not be unreasonably withheld).

     Section 8.05 Aggregation of Restricted Units. All Restricted Units held or acquired
by Persons who are Affiliates of one another shall be aggregated together for the purpose of
determining the availability of any rights under this Agreement.

     Section 8.06 [Reserved]

in writing and shall be given by regular mail, registered or certified mail, return receipt
requested, telecopy, air courier guaranteeing overnight delivery, electronic mail or personal
delivery to the addresses listed in Exhibit B of this Agreement or to such other address as
the Partnership or such Purchaser may designate in writing. All notices and communications shall
be deemed to have been duly given: at the time delivered by hand, if personally delivered; at the
time of transmittal, if sent via electronic mail; upon actual receipt if sent by registered or
certified mail, return receipt requested, or regular mail, if mailed; when receipt acknowledged, if
sent via facsimile; and upon actual receipt when delivered by air courier guaranteeing overnight

24

 

     Section 8.08 Removal of Legend. In connection with a sale of the Restricted Units by
a Purchaser in reliance on Rule 144, the applicable Purchaser or its broker shall deliver to the
transfer agent and the Partnership a broker representation letter providing to the transfer agent
and the Partnership any information the Partnership deems necessary to determine that the sale of
the Restricted Units is made in compliance with Rule 144, including, as may be appropriate, a
certification that the Purchaser is not an affiliate of the Partnership and regarding the length of
time the Restricted Units have been held. Upon receipt of such representation letter the
Partnership, the Partnership shall promptly direct its transfer agent to exchange unit certificates
bearing a restrictive legend for unit certificates without the legend (or a credit for such shares
to book-entry accounts maintained by the transfer agent), including the legend referred to in
Section 4.09, and the Partnership shall bear all costs associated therewith, including any
legal opinion required by the transfer agent in connection therewith. After any Purchaser or its
permitted assigns have held the Restricted Units for one year, if such Restricted Units still bear
the restrictive legend referred to in Section 4.09, the Partnership agrees to take all
steps necessary to promptly effect the removal of the legend described in Section 4.09 from
the Restricted Units, and the Partnership shall bear all costs associated therewith, regardless of
whether the request is made in connection with a sale or otherwise, so long as such Purchaser or
its permitted assigns provide to the Partnership any information the Partnership deems necessary to
determine that the legend is no longer required under the Securities Act or applicable state laws,
including a certification that the holder is not an affiliate of the Partnership and regarding the
length of time the Restricted Units have been held.

     Section 8.09 Entire Agreement. This Agreement and the other Basic Documents are
intended by the Parties as a final expression of their agreement and intended to be a complete and
exclusive statement of the agreement and understanding of the Parties hereto and thereto in respect
of the subject matter contained herein and therein. There are no restrictions, promises, warranties
or undertakings, other than those set forth or referred to herein and therein with respect to the
rights granted by the Partnership or a Purchaser set forth herein and therein. This Agreement and
the other Basic Documents supersede all prior agreements and understandings between the Parties
with respect to such subject matter. The Schedules and Exhibits referred to herein and attached
hereto are incorporated herein by reference, and unless the context expressly requires otherwise,
are incorporated in the definition of “Agreement.”

     Section 8.10 Governing Law. This Agreement will be construed in accordance with and
governed by the Laws of the State of Texas without regard to principles of conflicts of Laws that
would apply the substantive law of some other jurisdiction.

     Section 8.11 Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different Parties hereto in separate counterparts, each of which
counterparts, when so executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same Agreement.

     Section 8.12 Expenses. If any action at law or equity is necessary to enforce or
interpret the terms of the Basic Documents, the prevailing party shall be entitled to reasonable
attorney’s fees, out-of-pocket costs and necessary disbursements in addition to any other relief to
which such party may be entitled.

25

 

     Section 8.13 Obligations Limited to Parties to Agreement. Each of the Parties hereto
covenants, agrees and acknowledges that no Person other than the Purchasers (and their permitted
assignees) shall have any obligation hereunder and that, notwithstanding that one or more of the
Purchasers may be a corporation, partnership or limited liability company, no recourse under this
Agreement or the other Basic Documents or under any documents or instruments delivered in
connection herewith or therewith shall be had against any former, current or future director,
officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of
any of the Purchaser or any former, current or future director, officer, employee, agent, general
or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by
the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any
applicable Law, it being expressly agreed and acknowledged that no personal liability whatsoever
shall attach to, be imposed on or otherwise be incurred by any former, current or future director,
officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of
any of the Purchasers or any former, current or future director, officer, employee, agent, general
or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for
any obligations of the Purchasers under this Agreement or the other Basic Documents or any
documents or instruments delivered in connection herewith or therewith or for any claim based on,
in respect of or by reason of such obligation or its creation, except in each case for any assignee
of a Purchaser hereunder.

     Section 8.14 Waiver of Preemptive Right by General Partner. The General Partner
hereby waives (for itself and on behalf of its Affiliates) its preemptive rights provided under
Sections 5.2(b) and Section 5.8 of the Partnership Agreement with respect to the issuances of
Partnership Securities pursuant to this Agreement.

     Section 8.15 Termination.

     (a) Notwithstanding anything herein to the contrary, this Agreement may be terminated
at any time at or prior to the Closing by the mutual written consent of the Purchasers
entitled to purchase a majority of the Restricted Units and the Partnership.

     (b) Notwithstanding anything herein to the contrary, this Agreement shall automatically
terminate at any time at or prior to the Closing:

     (i) if a statute, rule, order, decree or regulation shall have been enacted or
promulgated, or if any action shall have been taken by any Governmental Authority of
competent jurisdiction which permanently restrains, precludes, enjoins or otherwise
prohibits the consummation of the transactions contemplated by this Agreement or
makes the transactions contemplated by this Agreement illegal; or

     (ii) if the Closing shall not have occurred on or before October 2, 2008.

     (c) In the event of the termination of this Agreement as provided in Sections
8.15(a) or 8.15(b), this Agreement shall forthwith become null and void. In the
event of such termination, there shall be no liability on the part of any Party hereto,
except as set

26

 

forth in Article VII of this Agreement and except with respect to the
requirement to comply with any confidentiality agreement in favor of the Partnership;
provided that nothing herein shall relieve any party from any liability or obligation with
respect to any willful breach of this Agreement.

Exhibit A

Form of Registration Rights Agreement

Exhibit A
– Page 1

 

 

Exhibit B

Form of Legal Opinion

     The Partnership shall furnish to the Purchasers at the Closing an opinion of Andrews Kurth
LLP, counsel for the Partnership, addressed to the Purchasers and dated the Closing Date, stating
that:

     a. Existence and Good Standing of the Partnership and the General Partner. Each of the
Partnership and the General Partner is validly existing and in good standing as a limited
partnership or limited liability company, respectively, under the Delaware LP Act and the Delaware
Limited Liability Company Act (the “Delaware LLC Act”), respectively. The Partnership has
the limited partnership power and authority under the laws of the State of Delaware to execute and
deliver, and incur and perform all of its obligations under the Securities Purchase Agreement.

     b. Capitalization. As of the Closing Date and immediately prior to the issuance of the
Restricted Units pursuant to the Securities Purchase Agreement and the Contribution Agreement, the
issued and outstanding limited partner interests of the Partnership consist of [57,196,211] Units,
[27,727,411] Subordinated Units and the Incentive Distribution Rights and the only issued and
outstanding general partner interest is the General Partner’s 2% general partner interest.

     c. Valid Issuance of Partnership Entity Equity. All of the outstanding Units have been duly
authorized and validly issued in accordance with the Delaware LP Act and the Partnership Agreement
and are fully paid (to the extent required by the Delaware LP Act and the Partnership Agreement)
and non-assessable (except as such non-assessability may be affected by matters described in
Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

     d. Due Authorization; Valid Issuance of Restricted Units. The issuance and sale of the
Restricted Units have been duly authorized on behalf of the Partnership. When delivered to and
paid for by the Purchasers in accordance with the terms of the Securities Purchase Agreement, the
Restricted Units will be validly issued in accordance with the Delaware LP Act and the Partnership
Agreement, fully paid (to the extent required by the Delaware LP Act and the Partnership Agreement)
and non-assessable (except as such non-assessability may be affected by Sections 17-303, 17-607 and
17-804 of the Delaware LP Act).

     e. No Violations. None of (i) the execution and delivery by the Partnership of the Securities
Purchase Agreement and the Registration Rights Agreement and (ii) the consummation by the
Partnership of the issuance and sale of the Restricted Units (A) constituted, constitutes or will
constitute a violation of the Partnership’s Certificate of Limited Partnership or the Partnership
Agreement, (B) constitutes or will constitute a breach or violation of, or a default under (or an
event which, with notice or lapse of time or both, would constitute such an event), any agreement
filed as an exhibit to the SEC Documents, or (C) resulted, results or will result in any violation
of the Delaware LP Act, the Delaware LLC Act or any applicable laws of the United States of
America, which violations, in the case of clauses (B) or (C) would be reasonably
expected to have a Partnership Material Adverse Effect; provided, however, such counsel may

Exhibit B
– Page 1

 

 

express no opinion pursuant to this paragraph with respect to federal securities Laws or state
securities or “Blue Sky” Laws or other anti-fraud Laws.

     f. Due Authorization of Transaction and Related Documents. Each of the Securities Purchase
Agreement and the Registration Rights Agreement has been duly authorized and validly executed and
delivered on behalf of the Partnership.

     g. Enforceability. Each of the Securities Purchase Agreement and the Registration Rights
Agreement constitutes a valid and binding obligation of the Partnership, enforceable against the
Partnership in accordance with its terms under the applicable laws of the State of Texas, except as
such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar Laws
affecting creditors’ rights generally or by general principles of equity, including principles of
commercial reasonableness, fair dealing and good faith, as well as other customary exceptions for
agreements of these types to be set forth in such opinion.

     h. No Approvals. No Governmental Approval, which has not been obtained or taken and is not in

ARTICLE II

REGISTRATION RIGHTS

     Section 2.01 Shelf Registration.

     (a) Deadline To Become Effective. As soon as practicable following the Closing Date,
but in any event within 120 days of the Closing Date, the Partnership shall prepare and file a
Shelf Registration Statement under the Securities Act with respect to all of the Registrable
Securities. 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 the Partnership.
The Partnership shall use its commercially reasonable efforts to cause the Shelf Registration
Statement to become effective no later than 180 days following the Closing Date (the “Target
Effective Date”). The Partnership will use its commercially reasonable efforts to cause the
Shelf Registration Statement filed pursuant to this Section 2.01 to be continuously
effective under the Securities Act until the earlier of (i) the date as of which all such
Registrable Securities are sold by the Purchasers and any transferee or assignee who was
transferred or assigned rights under this Agreement in accordance with Section 2.08 and
(ii) the date as of which all such Registrable Securities cease to be Registrable Securities
pursuant to Section 1.02 of this Agreement (the “Effectiveness Period”). The Shelf
Registration Statement when declared effective (including the documents incorporated therein by
reference) will comply as to form in all material respects with all applicable requirements of the
Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make the statements
therein not misleading (and, in the case of any prospectus contained in such Shelf Registration
Statement, in the light of the circumstances under which a statement is made). As soon as
practicable following the date that the Shelf Registration Statement becomes effective, but in any
event within five (5) Business Days of such date, the Partnership shall provide the Purchasers with
written notice of the effectiveness of the Shelf Registration Statement.

     (b) Failure To Become Effective. If the Shelf Registration Statement required by
Section 2.01 does not become or is not declared effective on or before the Target Effective
Date, then each Purchaser shall be entitled to a payment (with respect to the Restricted Units of
each such Purchaser), as liquidated damages and not as a penalty, (a) for each non-overlapping
30-day period for the first 60 days following the Target Effective Date, an amount equal to (i)
0.25% times (ii) the product of (A) the Unit Purchase Price times (B) the number of Restricted
Units

3

 

held by such Purchaser (such product of (A) and (B) being the “Liquidated Damages
Multiplier”), and (b) for each non-overlapping 30-day period beginning on the 61st day
following the Target Effective Date, with such payment amount increasing by an additional amount
equal to 0.25% times the Liquidated Damages Multiplier per non-overlapping 30-day period for each
subsequent 60 days up to a maximum amount equal to 1.0% times the Liquidated Damages Multiplier per
non-overlapping 30-day period (the “Liquidated Damages”) (i.e., 0.5% for 61-120 days; 0.75%
for 121-180 days; and 1.0% thereafter); provided, that the aggregate amount of Liquidated Damages
payable by the Partnership under this Agreement to each Purchaser shall not exceed 5.0% of the Unit
Purchase Price multiplied by the number of Restricted Units held by such Purchaser. The Liquidated
Damages payable pursuant to the immediately preceding sentence shall be payable within ten (10)
Business Days after the end of each such non-overlapping 30-day period. Any Liquidated Damages
shall be paid to each Purchaser in cash or immediately available funds; provided, however, if the
Partnership certifies that it is unable to pay Liquidated Damages in cash or immediately available
funds because such payment will violate a covenant in an existing credit agreement or other
indebtedness, then the Partnership may pay the Liquidated Damages in kind in the form of the
issuance of additional Units, unless otherwise not permitted. Upon any issuance of Units as
Liquidated Damages, the Partnership shall promptly (i) prepare and file an amendment to the Shelf
Registration Statement prior to its effectiveness adding such Units to such Shelf Registration
Statement as additional Registrable Securities and (ii) prepare and file a supplemental listing
application with the NYSE to list such additional Units. The determination of the number of Units
to be issued as Liquidated Damages shall be equal to the average of the closing sales prices of the
Partnership’s Units for the ten (10) trading days immediately preceding the date on which the
liquidated damages payment is due, less a discount of 2%. The payment of liquidated damages to a
Purchaser shall cease at the earlier of (i) such time as the Shelf Registration Statement is
declared effective or (ii) one year from the Closing Date.

     (c) Waiver of Liquidated Damages. If the Partnership is unable to cause a Shelf
Registration Statement to become effective by the Target Effective Date as a result of an
acquisition, merger, reorganization, disposition or other similar transaction, then the Partnership
may request a waiver of the Liquidated Damages, which may be granted by the consent of the Holders
of a majority of the outstanding Registrable Securities, in their sole discretion, and which such
waiver shall apply to all the Holders of Registrable Securities.

     (d) Delay Rights. Notwithstanding anything to the contrary contained herein, the
Partnership 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 but
may settle any previously made sales of Registrable Securities) if (i) the Partnership is pursuing
an acquisition, merger, reorganization, disposition or other similar transaction and the
Partnership determines in good faith that the Partnership’s 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) the Partnership has experienced some other material
non-public event the disclosure of which at such time, in the good faith judgment of the
Partnership, would materially adversely affect the Partnership; provided, however, in no event
shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Shelf

4

 

Registration Statement for a period that exceeds an aggregate of 60 days in any 180-day period
or 90 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement
executed by a Purchaser in connection with any Underwritten Offering. Upon disclosure of such
information or the termination of the condition described above, the Partnership 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 reasonable actions to permit registered sales of Registrable Securities
as contemplated in this Agreement.

     (e) Additional Rights to Liquidated Damages. If (i) the Holders shall be prohibited
from selling their Registrable Securities under the Shelf Registration Statement as a result of a
suspension pursuant to Section 2.01(d) of this Agreement in excess of the periods permitted
therein or (ii) the Shelf Registration Statement is filed and declared effective but, during the
Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended
purpose without being succeeded within 60 Business Days by a post-effective amendment to the Shelf
Registration Statement, a supplement to the prospectus or a report filed with the Commission
pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is
lifted or a post-effective amendment, supplement or report is filed with the Commission, but not
including any day on which a suspension is lifted or such amendment, supplement or report is filed
and declared effective, if applicable, the Partnership shall pay the Holders an amount equal to the
Liquidated Damages, following (x) the date on which the suspension period exceeded the permitted
period or (y) the sixty-first (61st) Business Day after the Shelf Registration Statement
ceased to be effective or failed to be useable for its intended purposes, as liquidated damages and
not as a penalty. For purposes of this Section 2.01(e), a suspension shall be deemed
lifted on the date that notice that the suspension has been lifted is delivered to the Holders
pursuant to Section 3.01 of this Agreement.

     (f) Termination of Rights. Other than as set forth otherwise in this Agreement, a
Holder’s rights (and any transferee’s rights pursuant to Section 2.08) under this
Section 2.01, including rights to Liquidated Damages (other than Liquidated Damages owing
but not yet paid), shall terminate upon the termination of the Effectiveness Period.

     (g) No Demand Rights. Notwithstanding any other provision of this Agreement, no
Holder of Registrable Securities shall be entitled to any “demand” rights or similar rights that
would require the Partnership to effect an underwritten offering solely on behalf of such Holder.

     Section 2.02 Sale Procedures. In connection with its obligations under this
Article II, the Partnership 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

5

 

request, copies of reasonably complete drafts of all such documents proposed to be filed
(including 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 commercially reasonable efforts to register or qualify the
Registrable Securities covered by the Shelf Registration Statement under the securities or blue sky
laws of such jurisdictions as the Selling Holders shall reasonably request; provided, however, that
the Partnership will not be required to qualify generally to transact business in any jurisdiction
where it is not then required to so qualify or to take any action which would subject it to general
service of process in any such jurisdiction where it is not then so subject;

     (d) promptly notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered by any of them 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 or any post-effective amendment thereto, when the same has become effective; and (ii) the
receipt of any written comments from the Commission with respect to any filing referred to in
clause (i) and any written request by the Commission for amendments or supplements to the
Shelf Registration Statement or any prospectus or prospectus supplement thereto;

     (e) immediately notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of (i) the happening of any event as a result of
which the prospectus or prospectus supplement contained in the Shelf Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein not misleading (in the
case of any prospectus contained therein, in the light of the circumstances under which a statement
is made); (ii) the issuance or express 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 the Partnership 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, the Partnership 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 commercially reasonable action as
is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

6

 

     (f) upon request and subject to appropriate confidentiality obligations, 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) 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, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

     (h) 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 the Partnership are then listed;

     (i) use its commercially reasonable 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 the Partnership to enable the Selling Holders to
consummate the disposition of such Registrable Securities;

     (j) 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;

     (k) if requested by a Purchaser, (i) incorporate in a prospectus supplement or post-effective
amendment such information as such Purchaser reasonably requests to be included therein relating to
the sale and distribution of Registrable Securities, including information with respect to the
number of Registrable Securities being offered or sold, the purchase price being paid therefor and
any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii)
make all required filings of such prospectus supplement or post-effective amendment after being
notified of the matters to be incorporated in such prospectus supplement or post-effective
amendment; and

     (l) The Partnership agrees that, if any Purchaser could reasonably be deemed to be an
“underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the Shelf
Registration Statement and any amendment or supplement thereof, then the Partnership will cooperate
with such Purchaser in allowing such Purchaser to conduct customary “underwriter’s due diligence”
with respect to the Partnership and satisfy its obligations in respect thereof. In addition, at
any Purchaser’s request, the Partnership will furnish to such Purchaser, on the date of the
effectiveness of the Shelf Registration Statement and thereafter from time to time on such dates as
such Purchaser may reasonably request, (i) a “cold comfort” letter, dated such date, from the
Partnership’s independent certified public accountants in form and substance as is customarily
given by independent certified public accountants to underwriters in an underwritten public
offering, addressed to such Purchaser, (ii) an opinion, dated as of such date, of counsel
representing the Partnership for purposes of the Shelf Registration Statement, in form, scope and
substance as is customarily given in an underwritten public offering, including a standard “10b-5”
opinion for such offering, addressed to such Purchaser and (iii) a standard officer’s certificate
from the chief executive officer or chief financial officer, or other officers serving such

7

 

functions, of the General Partner addressed to the Purchaser; provided, however, that with
respect to any Placement Agent, the Partnership’s obligations with respect to this Section
2.02(l) shall be limited to one time, with an additional bring-down request within 30 days of
the date of such documents.

     Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event
of the kind described in subsection (e) of this Section 2.02, shall forthwith
discontinue offers and sales of the Registrable Securities until such Selling Holder’s receipt of
the copies of the supplemented or amended prospectus contemplated by subsection (e) of this
Section 2.02 or until it is advised in writing by the Partnership 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 the Partnership, such Selling
Holder will, or will request the managing underwriter or underwriters, if any, to deliver to the
Partnership (at the Partnership’s expense) all copies in their possession or control, other than
permanent file copies then in such Selling Holder’s possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice.

     Section 2.03 Cooperation by Holders. The Partnership shall have no obligation to
include Registrable Securities of a Holder in the Shelf Registration Statement who has failed to
timely furnish such information that the Partnership determines, after consultation with its
counsel, is reasonably required in order for the registration statement or prospectus supplement,
as applicable, to comply with the Securities Act, including the execution of the initial Selling
Unitholder Notice and Questionnaire attached at Exhibit A to this Agreement by the date
specified thereon.

     Section 2.04 Restrictions on Public Sale by Holders of Registrable Securities. Each
Holder of Registrable Securities agrees that neither it nor its Affiliates will effect any public
sale or distribution of any Registrable Securities during the 30-day period beginning the day after
the pricing date of an Underwritten Offering of equity securities by the Partnership or its
Affiliates (except as provided in this Section 2.04); provided, however, that the duration
of the foregoing restrictions shall be no longer than the duration of the shortest restriction
generally imposed by the underwriters on the officers or directors or any other unitholder of the
Partnership on whom a restriction is imposed.

     Section 2.05 Expenses.

     (a) Expenses. The Partnership will pay all reasonable Registration Expenses as
determined in good faith. Each Selling Holder shall pay its pro rata share of all Selling Expenses
in connection with any sale of its Registrable Securities hereunder. In addition, except as
otherwise provided in Section 2.06 hereof, the Partnership shall not be responsible for
legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

     (b) Certain Definitions. “Registration Expenses” means all expenses incident
to the Partnership’s performance under or compliance with this Agreement to effect the registration
of Registrable Securities on the Shelf Registration Statement pursuant to Section 2.01 and
the disposition of such securities, including, without limitation, all registration, filing,
securities exchange listing and NYSE fees, all registration, filing, qualification and other fees
and expenses

8

 

of complying with securities or blue sky laws, fees of the Financial Industry Regulatory
Authority, fees of transfer agents and registrars, all word processing, duplicating and printing
expenses, any transfer taxes and the fees and disbursements of counsel and independent public
accountants for the Partnership, including the expenses of any special audits or “cold comfort”
letters required by or incident to such performance and compliance. “Selling Expenses”
means all underwriting fees, discounts and selling commissions or similar fees or arrangements
allocable to the sale of the Registrable Securities.

     Section 2.06 Indemnification.

     (a) By the Partnership. In the event of a registration of any Registrable Securities
under the Securities Act pursuant to this Agreement, the Partnership will indemnify and hold
harmless each Selling Holder thereunder, its directors, officers, employees and agents and each
Person, if any, who controls such Selling Holder and its directors, officers, employees or agents
(collectively, the “Selling Holder Indemnified Persons”), against any losses, claims,
damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively,
“Losses”), joint or several, to which such Selling Holder Indemnified 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 (in the case of any
prospectus, in light of the circumstances under which such statement is made) contained in the
Shelf Registration Statement, any preliminary prospectus, prospectus supplement, free writing
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 Indemnified 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 the Partnership 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 Indemnified Person in writing specifically for use in the Shelf Registration Statement, or
prospectus supplement, as applicable. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Selling Holder Indemnified 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 the Partnership, its directors, officers, employees and agents and each
Person, if any, who controls the Partnership within the meaning of the Securities Act or of the
Exchange Act, and its directors, officers, employees and agents, to the same extent as the
foregoing indemnity from the Partnership 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, any preliminary prospectus,
prospectus supplement, free writing prospectus or final prospectus contained therein, or any
amendment or supplement thereof; 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

9

 

Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise
to such indemnification.

     (a) 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 2.06. 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 2.06 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 or employ counsel reasonably acceptable to the
indemnified party 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 any 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.

     (b) Contribution. If the indemnification provided for in this Section 2.06 is
held by a court or government agency of competent jurisdiction to be unavailable to any indemnified
party or is insufficient to hold them 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 Loss in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of such
indemnified party 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 the
indemnifying party on the one hand and the indemnified party 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

10

 

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 herein. 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.

     (c) Other Indemnification. The provisions of this Section 2.06 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 2.07 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, the Partnership agrees to use its commercially
reasonable efforts to:

     (a) Make and keep public information regarding the Partnership available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from and after the date
hereof;

     (b) File with the Commission in a timely manner all reports and other documents required of
the Partnership 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, unless otherwise available
via EDGAR, to such Holder forthwith upon request a copy of the most recent annual or quarterly
report of the Partnership, 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 2.08 Transfer or Assignment of Registration Rights. The rights to cause the
Partnership to register Registrable Securities granted to the Purchasers by the Partnership under
this Article II may be transferred or assigned by any Purchaser to one or more
transferee(s) or assignee(s) of such Registrable Securities or counterparties to any total return
swaps; provided, however, that, (a) unless such transferee is an Affiliate of such Purchaser, or a
counterparty to a total return swap, each such transferee or assignee holds Registrable Securities
representing at least $10 million of the Restricted Units, based on the Unit Purchase Price, (b)
the Partnership 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 assumes in
writing responsibility for its portion of the obligations of such Purchaser under this Agreement.

     Section 2.09 Limitation on Subsequent Registration Rights. From and after the date
hereof, the Partnership shall not, without the prior written consent of the Holders of a majority
of

11

 

the outstanding Registrable Securities, enter into any agreement with any current or future
holder of any securities of the Partnership that would allow such current or future holder to
require the Partnership to include securities in any registration statement filed by the
Partnership on a basis that is superior in any way to the registration rights granted to the
Purchasers hereunder.

will have the right to an injunction or other equitable relief in any court of competent

Agreement without regard to principles of conflicts of Laws that would apply the substantive law of
some other jurisdiction.

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition or unenforceability without invalidating the remaining provisions
hereof or affecting or impairing the validity or enforceability of such provision in any other
jurisdiction.

     Section 3.11 Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject matter contained
herein. There are no restrictions, promises, warranties or undertakings, other than those set
forth or referred to herein with respect to the rights granted by the Partnership set forth herein.
