ARTICLE IV

WITHDRAWAL

     4.1 No Voluntary Withdrawal. A notice by a Partner that it has Withdrawn from the
Partnership shall be in breach of this agreement and shall be deemed to effect a wrongful
Withdrawal.

     4.2 Deemed Withdrawal. A Partner shall be deemed to have Withdrawn from the
Partnership immediately, without any further action on the part of such Partner or the Partnership,
only on the occurrence of any event (i) that makes it unlawful for the Partner to
continue to be a Partner, (ii) that makes it unlawful for the Partnership to carry on the
Partnership Business with that Partner or (iii) specified in Section 15-601(6) of the Act. A
Partner shall not be deemed to have Withdrawn from the Partnership for any events not specified in
Section 4.1 or this Section 4.2.

     4.3 Effect of Withdrawal. If a Partner Withdraws as contemplated in Section
4.1 or is deemed to have Withdrawn under Section 4.2 (a “Withdrawn Partner”), then the
following provisions shall apply in connection with such Withdrawal, notwithstanding the provisions
of the Act:

     (a) The Withdrawn Partner shall cease to be a Partner for all purposes immediately upon
the occurrence of the applicable Withdrawal event.

     (b) The Withdrawn Partner shall not be entitled to receive any distributions from the
Partnership except as set forth in Section 4.3(f), and the Withdrawn Partner shall
not be entitled to exercise any voting or consent rights with respect to Partnership matters
or to receive any further information from the Partnership. The Sharing Ratio of such
Withdrawn Partner shall not be taken into account in calculating the Sharing Ratios of the
Partners for any purposes.

     (c) The Withdrawn Partner must pay to the Partnership all amounts it owes to the
Partnership.

     (d) The Withdrawn Partner shall remain obligated for all liabilities it may have under
this Agreement with respect to the Partnership that accrue with respect to the period prior

     (e) Upon the occurrence of the applicable Withdrawal event or deemed Withdrawal, (i)
all of the GP Units held by such Withdrawn Partner (the “Forfeited GP Units”) shall
automatically, without any further action on the part of the Withdrawn Partner or the
Partnership, be redeemed, forfeited, surrendered and transferred to the Partnership for no
consideration (except as otherwise provided in Section 4.3(f)), (ii) such Withdrawn
Partner shall not be entitled to any rights with respect to the Forfeited GP Units, (iii)
any certificates representing the Forfeited GP Units shall be null and void, and (iv) any MC
Member previously designated by such Withdrawn Partner shall be deemed to be removed. If a
Partner Withdraws as contemplated in Section 4.1, then such Withdrawn Partner’s
Capital Account shall be allocated among the remaining Partners in the proportion that each
Partner’s Sharing Ratio (at the time of such allocation) bears to

-16-

 

the total Sharing Ratio of
all remaining Partners, or in such other proportion as the remaining Partners may
unanimously agree.

     (f) If a Partner is deemed to be a Withdrawn Partner pursuant to Section 4.2,
then the former Capital Account balance of the Withdrawn Partner shall be recorded as a
contingent obligation of the Partnership, and not as a Capital Account, and such former
Capital Account balance shall be paid by the Partnership to such Withdrawn Partner solely
out of 25% of the future distributions (if any) that would have been made by the Partnership
to the Withdrawn Partner if the Forfeited GP Units remained outstanding
after the date of such Withdrawal; provided, that any amounts owed to the Partnership
by such Withdrawn Partner may be deducted from any such distributions. The rights of a
Withdrawn Partner under this Section 4.3(f) shall (i) be subordinate to the rights
of any other creditor of the Partnership, (ii) not include any right on the part of the
Withdrawn Partner to receive any interest or other amounts with respect thereto; (iii) not

Management Committee may, in its Sole Discretion, decide to cause the Partnership to make);
(iv) not require any Partner to make a Capital Contribution or a loan to permit the
Partnership to make a distribution or otherwise to pay the Withdrawing Partner; and (v) not
be treated as a liability of the Partnership for purposes of Section 10.2. Any
portion of such Withdrawn Partner’s former Capital Account in excess of amounts paid to it
under this Section 4.3(f) shall be allocated among the remaining Partners in
proportion to each Partner’s Sharing Ratio or as the remaining Partners otherwise
unanimously agree.

     (g) Each Partner hereby constitutes and appoints the Partnership as its agent and
attorney-in-fact, in the event such Partner becomes a Withdrawn Partner hereunder, for the
purposes of executing and delivering any and all documents necessary to effectuate the
forfeiture of its GP Units in accordance with this Section 4.3. This
power-of-attorney, being coupled with an interest, is irrevocable and shall survive the
dissolution, disability or incapacitation of any Partner.

ARTICLE V

     (b) Alinda Investor 1 contributed to the Partnership an amount in cash equal to

-17-

 

     (c) Alinda Investor 2 contributed to the Partnership an amount in cash equal to
$217,969,000, and in exchange for such Capital Contribution, the Partnership issued to
Alinda Investor 2 217,969 GP Units; and

Contribution Agreement), and in exchange for such Capital Contribution, the Partnership
issued to Regency HIG 400,000 GP Units. The Partners hereby acknowledge and agree that, for
all purposes, the agreed net fair market value of such Capital
Contribution (after giving effect to the payment pursuant to Section 9.6) is
equal to $400,000,000.

     5.2 Additional Capital Contributions.

     (a) If at any time the Management Committee determines to raise additional capital for
the Partnership for any Partnership Business purpose, then the Management Committee shall
first issue a written notice to the Partners (a “Call Notice”) setting forth the amount of
Capital Contributions the Management Committee desires to raise (the “Call Amount”) and the
intended purpose of such Capital Contributions, the number of GP Units to be issued with
respect to such Capital Contributions and the date on which such Capital Contributions are
due, and each Partner shall have the right, but not the obligation, to contribute its pro
rata share based on its Sharing Ratio (as of the date of such Call Notice) of such Call
Amount in accordance with this Section 5.2(a). If any Partner desires to exercise
its rights under this Section 5.2(a), it must deliver a written notice to the
Partnership and each other Partner within ten Business Days after the Partner’s receipt of
the Call Notice (the “Election Period”) setting forth the portion of the Call Amount such
Partner (the “Electing Partner”) is electing to contribute, up to its Sharing Ratio plus any
additional portion of the Call Amount it desires to contribute in excess of its Sharing
Ratio (the “Over-Allotment Amount”) if other Partners do not exercise all or any portion of
their rights hereunder. The right of each Electing Partner to fund the Call Amount in
excess of its Sharing Ratio shall be based on the relative Sharing Ratios of the Electing
Partners desiring to fund Over-Allotment Amounts (or in such other manner as all of the
Electing Partners agree to allocate the right to fund among themselves). If any Electing
Partner elects to contribute any portion of the Call Amount, such Electing Partner shall be
obligated to make such Capital Contribution on the date set forth in the Call Notice (or
such other date as the Management Committee may determine), and upon receipt of such Capital
Contribution, the Partnership shall issue to such Electing Partner the number of GP Units
applicable to the portion of the Call Amount contributed by such Electing Partner.
Notwithstanding the foregoing, with respect to any two Partners that are Affiliates, at the
election of such Partners, one such Partner shall be entitled to contribute all or a portion
of the other such Partner’s pro rata share of any Call Amount or Over-Allotment Amount. Any
such issuance and payment in respect thereof shall be delayed, to the extent required, to
obtain any necessary governmental approvals, waivers and consents required for such issuance
(including any approvals under the HSR Act); provided, that if such approval, waiver or
consent is required by any Electing Partner to consummate such closing and such approval,
waiver or consent is not obtained within 40 Business Days after the scheduled closing date,
then such Electing Partner shall be deemed to have waived its right to contribute any
portion

-18-

 

of the Call Amount and such Electing Partner shall not be deemed to have breached
its obligation to contribute such portion of the Call Amount.

     (b) If one or more Partners do not elect, in the aggregate, to contribute all of the
Call Amount (or are deemed to have waived such right), the Partnership shall have the right,
but not the obligation, to issue and sell to one or more Persons up to the number of GP
Units (as determined by the Management Committee) applicable to the portion of
the Call Amount not contributed by the Partners at any time during the 90 Business Days
following the end of the Election Period, for an aggregate amount equal to the applicable
portion of the Call Amount not contributed by the Partners; provided, that if the
Partnership fails to issue and sell such GP Units for such aggregate amount within such
90-Business Day period, the Partnership may not raise any additional capital without first
issuing another Call Notice pursuant to Section 5.2(a). The issuance of any GP
Units to any Person shall be subject to such terms and procedures as the Management
Committee determines are necessary or desirable, including obtaining any necessary
governmental approvals, waivers and consents required for such issuance (including any
approvals under the HSR Act).

     (c) Notwithstanding anything to the contrary in this Agreement, if any Electing Partner
breaches its obligation to contribute any portion of the Call Amount it elected to
contribute pursuant to Section 5.2(a), then in addition to any other rights the
Partnership and the non-breaching Partners may have at law or in equity, such breaching
Partner and any transferee thereof shall not have any future rights granted under
Section 5.2(a) unless the Management Committee expressly designates otherwise (which
the Management Committee may do on an offer-by-offer basis or not at all); provided, that
the MC Member designated by the breaching Partner shall not be entitled to participate in
(i) any decisions regarding the number of GP Units to be issued with respect to such Call
Notice or (ii) any decisions regarding whether such breaching Partner has any future rights
under Section 5.2(a).

     5.3 No Other Required Capital Contributions. Except as otherwise expressly provided
in this Agreement or required by Law and except for the Initial Capital Contributions, no Partner
has any obligation to make any Capital Contributions to the Partnership.

     5.4 Return of Contributions. Except as expressly provided in this Agreement to the
contrary, a Partner is not entitled to the return of any part of its Capital Contributions or to be
paid interest in respect of either its Capital Account or its Capital Contributions. An unrepaid
Capital Contribution is not a liability of the Partnership or of any Partner. A Partner is not
required to contribute or to lend any cash or property to the Partnership to enable the Partnership
to return any Partner’s Capital Contributions.

     5.5 Use of Proceeds. Notwithstanding anything to the contrary in this Agreement,
neither the Partnership, the Management Committee, the Management Company nor any Partner may use
any of the proceeds of any Initial Capital Contribution for any purpose except to (a) make
expenditures with respect to the Haynesville Expansion Project in accordance with the Budgets or
(b) pay to Regency HIG, in accordance with the terms of Article 2 of the

-19-

 

Contribution Agreement,
the Pre-Closing Expenditures (as defined in the Contribution Agreement).

     5.6 Capital Accounts.

     (a) A Capital Account shall be established and maintained for each Partner in
accordance with the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv).

     (b) Each Partner’s Capital Account shall be increased by (i) the amount of money
contributed by that Partner to the Partnership, (ii) the Book Value of property contributed
by that Partner to the Partnership (net of liabilities secured by such contributed property
that the Partnership is considered to assume or take subject to under Section 752 of the
Code), and (iii) allocations to that Partner of Profits and any other items of Partnership
income and gain, and shall be decreased by (x) the amount of money distributed to that
Partner by the Partnership, (y) the Book Value of property distributed to that Partner by
the Partnership (net of liabilities secured by such distributed property that such Partner
is considered to assume or take subject to under Section 752 of the Code), and (z)
allocations to that Partner of Losses and any other items of Partnership loss and deduction.

     (c) The Partners’ Capital Accounts shall also be maintained and adjusted as permitted
by the provisions of Treasury Regulation § 1.704-1(b)(2)(iv)(f) and as required by the other
provisions of Treasury Regulation §§ 1.704-1(b)(2)(iv) and 1.704-1(b)(4). A Partner who has
more than one GP Unit shall have a single Capital Account that reflects all such GP Units,
regardless of the time or manner in which such GP Units were acquired. Upon the Transfer of
a GP Unit, the Capital Account of the Transferring Partner that is attributable to such GP
Unit shall carry over to the assignee in accordance with the provisions of Treasury
Regulation § 1.704-1(b)(2)(iv)(l).

     (d) Whenever the fair market value of the Partnership’s property is required to be
determined pursuant to this Section 5.6, the Management Committee shall establish
the fair market value in a notice to the Partners (except in the case of the Initial Capital
Contribution of Regency HIG, which the Partner’s agree is the amount set forth on
Schedule 1 opposite Regency HIG’s name in the column title “Initial Capital
Contribution”).

distributions or with respect to allocations to the Partners and to pay over to any federal,
foreign, state or local government any amounts required to be so withheld pursuant to
the Code or any provision of any other federal, foreign, state or local tax law or treaty.
All amounts withheld pursuant to the Code or any provision of any other federal, foreign,
state or local tax law or treaty with respect to any payment, distribution or allocation to
the Partnership or the Partners shall be treated as amounts distributed to the Partner or
Partners with respect to which such amounts were withheld pursuant to this Article
VI for all purposes of this Agreement.

     (d) Limitations on Distribution. Except as provided in this Agreement, no
Partner shall be entitled to any distribution of cash or other property from the

Partnership shall not make a distribution to any Partner on account of its GP Units if such
distribution would violate the Act or other applicable Law.

     (e) Haynesville Expansion Project Distributions. If any proceeds of the
Initial Capital Contributions remain after the completion of the Haynesville Expansion
Project in accordance with the Haynesville Expansion Budget, then, as soon as practicable
following the completion of the Haynesville Expansion Project, such remaining proceeds shall

time such distribution is made).

     6.2 Allocations.

     (a) General. For purposes of maintaining the Capital Accounts pursuant to
Section 5.6, after making all allocations under Sections 6.2(b) and
6.2(c) for the taxable year, Profits and Losses and items thereof, for each taxable
year, shall be allocated among the Partners in such manner that, as of the end of such
period and to the extent possible, the Capital Account of each Partner shall be equal,
proportionately, to the excess of (1) the amount that would be distributed to such Partner
if the Company were to (A) liquidate its assets for an amount equal to their Book Value and
(B) distribute the proceeds in accordance with Section 6.1(a), over (2) the sum of (A) the
amount, if any, which such Partner is obligated to contribute to the capital of the
Partnership, (B) such Partner’s share of the Minimum Gain determined pursuant to Treasury
Regulation Section 1.704-2(g), and (C) such Partner’s share of Partner Nonrecourse Debt
Minimum Gain determined pursuant to Treasury Regulation Section 1.704-2(i)(5), all computed

items of deduction or loss arising from the expenditure of funds contributed to the
Partnership by Regency HIG pursuant to Section 9.7 and any Indemnity Loss shall be
allocated solely to Regency HIG.

-21-

 

Losses and certain other items of deduction and loss specially allocated to a Partner
pursuant to Section 6.2(b) shall not exceed the maximum amount of Losses and items
of deduction and loss that can be allocated without causing such Partner to have a deficit
in its Adjusted Capital Account at the end of any taxable year or other period. In the
event that some but not all of the Partners would have a deficit in their Adjusted Capital
Account as a consequence of an allocation pursuant to Section 6.2(b), the limitation
set forth in the preceding sentence shall be applied on a Partner by Partner basis and
Losses
or items of deduction and loss not allocable to any Partner as a result of such limitation
shall be allocated to the other Partners in accordance with the relative positive balances
in such Partners’ Capital Accounts so as to allocate the maximum permissible Losses or items
of deduction and loss to each Partner under Treasury Regulation Section
1.704-1(b)(2)(ii)(d).

     (b) Special Allocations. Notwithstanding any other provisions of this Section
6.2, the following special allocations shall be made in the following order for each taxable
period:

     (i) Notwithstanding any other provision of this Section 6.2, if there
is a net decrease in Minimum Gain during any taxable year, each Partner shall be
allocated items of Partnership income and gain for such year (and, if necessary,
subsequent taxable years) in the manner and amounts provided in Treasury Regulation
Sections 1.704-2(f)(6), (g)(2) and (j)(2)(i). For purposes of this Section 6.2(b),
each Partner’s Capital Account balance shall be determined, and the allocation of
income or gain required hereunder shall be effected, prior to the application of any
other allocations pursuant to this Section 6.2 with respect to such taxable
year. This Section 6.2(b)(i) is intended to comply with the minimum gain
chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be
interpreted consistently therewith.

     (ii) Notwithstanding the other provisions of this Section 6.2 (other
than Section 6.2(b)(i) above), if there is a net decrease in Partner
Nonrecourse Debt Minimum Gain during any taxable year, any Partner with a share of
Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable year shall be
allocated items of Partnership income and gain for such year (and, if necessary,
subsequent taxable years) in the manner and amounts provided in Treasury Regulation
Section 1.704-2(i)(4) and (j)(2)(ii). For purposes of this Section 6.2(b),
each Partner’s Adjusted Capital Account balance shall be determined, and the
allocation of income and gain required hereunder shall be effected, prior to the
application of any other allocations pursuant to this Section 6.2, other
than Section 6.2(b)(i) above, with respect to such taxable year. This
Section 6.2(b)(ii) is intended to comply with the partner nonrecourse debt
minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(i)(4) and
shall be interpreted consistently therewith.

     (iii) Except as provided in Sections 6.2(b)(i) and 6.2(b)(ii)
above, in the event any Partner unexpectedly receives an adjustment, allocation or
distribution described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5)
or (6), items

-22-

 

of Partnership income and gain shall be allocated to such Partner in
an amount and manner sufficient to eliminate, to the extent required by such
Treasury Regulation, the deficit balance, if any, in its Adjusted Capital Account
created by such adjustment, allocation or distribution as quickly as possible unless
such deficit balance is otherwise eliminated pursuant to Sections 6.2(b)(i),
6.2(b)(ii) or 6.2(b)(iv). This Section 6.2(b)(iii) is
intended to constitute a qualified income
offset described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall
be interpreted consistently therewith.

     (iv) In the event any Partner has a deficit balance in its Adjusted Capital
Account at the end of any taxable year, such Partner shall be allocated items of
Partnership gross income and gain in the amount of such excess as quickly as
possible; provided, however, that an allocation pursuant to this Section
6.2(b)(iv) shall be made only if and to the extent that such Partner would have
a deficit balance in its Adjusted Capital Account after all other allocations
provided in this Section 6.2(b) (other than Section 6.2(b)(iii))
have been tentatively made as if Section 6.2(b)(iii) and this Section
6.2(b)(iv) were not in this Agreement.

     (v) Nonrecourse Deductions for any taxable year shall be allocated to the
Partners in accordance with their Sharing Ratios.

     (vi) Partner Nonrecourse Deductions for any taxable year shall be allocated
100% to the Partner that bears the Economic Risk of Loss with respect to the Partner
Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in
accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner
bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, Partner
Nonrecourse Deductions attributable thereto shall be allocated between or among such
Partners in accordance with the ratios in which they share such Economic Risk of
Loss. This Section 6.2(b)(vi) is intended to comply with the provisions of
Treasury Regulation Section 1.704-2(i) and shall be interpreted consistently
therewith.

     (vii) To the extent an adjustment to the adjusted tax basis of any Partnership
asset pursuant to Code Sections 734(b) or 743(b) is required, pursuant to Treasury
Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining
Capital Accounts as a result of a distribution in liquidation of a Partner’s
Interest in the Partnership, the amount of such adjustment to the Capital Accounts
shall be treated as an item of gain (if the adjustment increases the basis of the
asset) or loss (if the adjustment decreases such basis), and such item of gain or
loss shall be allocated to the Partners in a manner consistent with the manner in
which their Capital Accounts are required to be adjusted pursuant to such
provisions.

     (c) Curative Allocation. The allocations set forth in Section 6.2(b)
(the “Regulatory Allocations”) are intended to comply with certain requirements of the
Treasury Regulations. It is the intent of the Partners that, to the extent possible, all
Regulatory Allocations shall be offset either with other Regulatory Allocations or with

-23-

 

special allocations of other items of Partnership income, gain, loss, or deduction pursuant
to this Section 6.2(c). Therefore, notwithstanding any other provision of this
Article VI (other than the Regulatory Allocations), but subject to the Code and the
Treasury Regulations, the Management Committee shall make such offsetting special
allocations of Partnership income, gain, loss, or deduction in whatever manner it determines
appropriate so that, after such offsetting allocations are made, each
Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account
balance such Partner would have had if the Regulatory Allocations were not part of this
Agreement. In exercising its discretion under this Section 6.2(c), the Management
Committee shall take into account future Regulatory Allocations that, although not yet made,
are likely to offset other Regulatory Allocations previously made.

     (d) Income Tax Allocations.

     (i) Except as otherwise provided in this Section 6.2, each item of
income, gain, loss and deduction of the Partnership shall be allocated among the
Partners for federal income tax purposes in the same manner as such items are
allocated under Sections 6.2(a), 6.2(b) and 6.2(c).

     (ii) For income tax purposes, income, gain, loss, and deduction with respect to
property contributed to the Partnership by a Partner or the Book Value of which is
adjusted pursuant to clause (b) or (d) of the definition of Book Value shall be
allocated among the Partners in a manner that takes into account the variation
between the adjusted tax basis of such property and its Book Value, as required by
Section 704(c) of the Code and Treasury Regulation Section 1.704-1(b)(4)(i), using
the remedial allocation method permitted by Treasury Regulation Section 1.704-3(d).

     (iii) All items of income, gain, loss, deduction and credit allocated to the
Partners in accordance with the provisions hereof and basis allocations recognized
by the Partnership for federal income tax purposes shall be determined without
regard to any election under Code Section 754 which may be made by the Partnership.

     (iv) If any deductions for depreciation or cost recovery are recaptured as
ordinary income upon the sale or other disposition of Partnership properties, the
ordinary income character of the gain from such sale or disposition shall be
allocated among the Partners in the same ratio as the deductions giving rise to such
ordinary income character were allocated.

The tax depreciation for the portion of the book basis (within the meaning of Treasury Regulation
Section 1.704-3(d)(2)) of the assets owned by RIGS (as defined in the Contribution Agreement) that
exceeds the tax basis of such assets will be MACRS depreciation plus all applicable bonus
depreciation.

     6.3 Varying Interests. All items of income, gain, loss, deduction and credit
allocable to GP Units that may have been transferred shall be allocated between the transferor and
the

-24-

 

transferee as determined by the Management Committee in accordance with a method permissible
under Code Section 706 and the Treasury Regulations thereunder. All distributions shall be made,
to the Persons shown on the records of the Partnership to have been Partners as of the last
calendar day of the period for which the allocation or distribution is to be made. Notwithstanding
the foregoing, if during any taxable year there is a change in any Partner’s Sharing Ratio, the
Partners agree that their allocable shares of items for the taxable year shall be
determined on any method determined by the Management Committee to be permissible under Code
Section 706 and the related Treasury Regulations to take account of the Partners’ varying Sharing
Ratios.

Notwithstanding the foregoing, if the Management Committee fails to approve an
Operating Budget with respect to any calendar year, then (i) the Operating Budget
previously approved by the Management Committee for the prior calendar year shall
remain in effect after giving effect to any dispositions or other material changes
to the assets of the Partnership during such prior calendar year, (ii) any items of
the proposed Operating Budget that have been approved by the Management Committee
shall become effective, and (iii) the Senior Management Team and the Management
Company will be entitled to expend Partnership funds, in any calendar quarter, in an
amount equal to the lesser of (1) the actual expenses incurred by the Partnership
and its subsidiaries in such calendar quarter, and (2) the budgeted amount for the
corresponding calendar quarter in the Operating Budget previously approved by the
Management Committee for the prior calendar year increased by the CPI Price Factor
(excluding any nonrecurring maintenance and capital expenditures). For the
avoidance of doubt, if, with respect to any calendar year, the Operating Budget for
the prior calendar year remains in effect pursuant to this Section 7.11(a),
then such prior calendar year’s Operating Budget shall be deemed to exclude any
Expansion Capital Expenditures set forth in such prior calendar year’s Operating
Budget and expended during such prior calendar year.

     (b) Haynesville Expansion Budget. The Haynesville Expansion Budget is attached
as Exhibit F. By execution of this Agreement, the Partners hereby (and the
Management Committee is deemed to) approve and consent to such Haynesville Expansion Budget
and acknowledge and agree that such Haynesville Expansion Budget shall be deemed to be the
Haynesville Expansion Budget for purposes of the MSA. The Haynesville Expansion Budget may
only be amended with the consent of the Management Committee.

ARTICLE VIII

TAX MATTERS

     8.1 Tax Returns. The Partnership shall cause a nationally recognized accounting firm
to prepare, at the expense of the Partnership, for each calendar year (or part thereof), federal
tax returns in compliance with the provisions of the Code and any required state and local tax
returns. Each Partner shall furnish to the Partnership all pertinent information in its possession
relating to the Partnership’s operations that is necessary to enable the Partnership’s tax
returns to be timely prepared and filed. Not less than 60 days prior to the due date (as extended)
of the Partnership’s federal income tax return or any state income tax return, the return proposed
by the Management Committee to be filed by the Partnership shall be furnished to the Partners for
review. In addition, not more than ten days after the date on which the Partnership files its
federal income tax return or any state income tax return, a copy of the return so filed shall be
furnished to the Partners.

     8.2 Partner Tax Return Information. The Partnership, at its expense, shall cause to
be delivered to each Partner within 75 days after the end of the Partnership’s taxable year an IRS
Form K-1 or a good faith estimate of the amounts to be included on such IRS Form K-1 for such
Partner and such other information as shall be necessary (including a statement for that year of
each Partner’s share of net income, net losses and other items allocated to such Partner) for the
preparation and timely filing by the Partners of their federal, state and local income and other
tax returns.

     8.3 Tax Matters Partner.

     (a) The “Tax Matters Partner” of the Partnership for purposes of Section 6231(a)(7) of
the Code shall be Regency HIG so long as its Ultimate Parent is Regency Energy Partners LP,
and otherwise shall be the Partner selected by the Management Committee for such purposes.
The Tax Matters Partner shall take such action as may be necessary to cause any Partner so
requesting to become a “notice partner” within the meaning of Section 6231(a)(8) of the
Code. The Tax Matters Partner shall inform each other Partner of all significant matters
that may come to its attention in its capacity as Tax Matters Partner by giving notice
thereof on or before the fifth day after becoming aware thereof and, within that time, shall
forward to each other Partner copies of all significant written communications it may
receive in that capacity. Any cost or expense incurred by the Tax Matters Partner in
connection with its duties, including the preparation for or pursuance of administrative or
judicial proceedings, shall be paid by the Partnership.

     (b) Without first obtaining the approval of the Management Committee, the Tax Matters
Partner shall not, with respect to Partnership tax matters: (i) enter into a settlement
agreement with respect to any tax matter which purports to bind Partners, (ii) intervene in
any action pursuant to Code Section 6226(b)(5), (iii) enter into an agreement extending the
period of limitations for making assessments on behalf of Partners, or (v) file a petition
pursuant to Code Section 6226(a) or 6228. If an audit of any of the Partnership’s tax
returns shall occur, the Tax Matters Partner shall not settle or otherwise compromise
assertions of the auditing agent which may be adverse to any Partner as

-35-

 

compared to the
position taken on the Partnership’s tax returns without the prior written consent of each
such affected Partner.

     (c) No Partner shall file a request pursuant to Code Section 6227 for an administrative
adjustment of Partnership items for any taxable year, or a petition under Code Sections 6226
or 6228 or other Code sections with respect to any item involving the Partnership, without
first notifying other Partners. Any Partner that enters into a
settlement agreement with respect to any Partnership item (within the meaning of Code
Section 6231(a)(3)) shall notify the other Partners of such settlement agreement and its
terms within 90 days from the date of the settlement.

     (d) If any Partner intends to file a notice of inconsistent treatment under Code
Section 6222(b), such Partner shall give reasonable notice under the circumstances to the
other Partners of such intent and the manner in which the Partner’s intended treatment of an
item is (or may be) inconsistent with the treatment of that item by the other Partners.

     8.4 Tax Elections. The Partnership shall make the following elections on the
appropriate forms or tax returns:

     (a) to adopt the calendar year as the Partnership’s fiscal year, if permitted under the
Code;

     (b) to adopt the accrual method of accounting;

     (c) if there is a distribution of Partnership property as described in Code Section 734
or a transfer of Partnership Interests as described in Code Section 743, upon request by
notice from any Partner, to elect, pursuant to Code Section 754, to adjust the basis of
Partnership property;

     (d) to elect to amortize the organizational expenses of the Partnership as permitted by
Code Section 709(b);

     (e) to take all available bonus depreciation for federal, state and local tax purposes,
unless otherwise determined by the Management Committee; and

     (f) any other election the Management Committee may deem appropriate.

     8.5 Tax Reimbursement. If Texas law requires the Partnership and any Partner both to
participate in the filing of a Texas franchise tax combined group report, and if such Partner or
any other member of the Partner’s combined group pays the franchise tax liability due in connection
with such combined report, the parties agree that the Partnership shall promptly reimburse such
Partner for the franchise tax paid on behalf of the Partnership as a combined group member. The
franchise tax paid on behalf of the Partnership shall equal the excess, if any of (i) the franchise
tax that the combined group including the Partnership pays over (ii) the amount the combined group
would have paid if it had computed its franchise tax liability for the report period without the
Partnership as a member of the combined group, but in no event more than what the Partnership would
have paid had it filed the franchise tax return not as a member of a group. In such event, the
parties agree that such Partner shall be considered as paying such

-36-

 

amount on behalf of the
Partnership and the Partnership shall deduct for federal income tax purposes 100% of the Texas
franchise tax attributable to the Partnership; provided that in the event that such deduction may
not be properly taken by the Partnership, the Partnership shall reimburse such Partner for the
after-tax cost of such payment of Texas franchise tax paid on the Partnership’s behalf.

     8.6 Tax Partnership. It is the intention of the Partners that the Partnership be
classified as a partnership for U.S. federal tax purposes. Neither the Partnership nor any Partner
shall make an election for the Partnership to be excluded from the application of the provisions of
subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state
law or to be classified as other than a partnership pursuant to Treasury Regulation Section
301.7701-3 or any similar provision of state or local law.

ARTICLE IX

BOOKS AND RECORDS; ADDITIONAL COVENANTS

     9.1 Maintenance of Books. The Partnership shall keep complete and accurate books and
records of Partnership, including all books and records necessary to provide to the Partners any
information required to be provided pursuant to Section 9.2, supporting documentation of
the transactions with respect to the conduct of the Partnership’s business and minutes of the
proceedings of the Partners and the Management Committee, and any other books, records and
information that are required to be maintained by applicable Law.

     9.2 Financial Statements and Reports. With respect to each calendar year, and within
the time frame specified by the Management Committee, the Partnership shall, or shall cause the
Management Company to, prepare and deliver to each Partner:

     (a) no later than 60 days after the end of each calendar year, annual financial

statement of cash flows and statement of Capital Accounts, as of the end of and for the
prior calendar year, which shall be prepared in accordance with generally accepted
accounting principles consistently applied (“GAAP”) and audited by the Partnership’s
independent certified public accountants, which shall be a nationally recognized accounting
firm;

     (b) no later than 40 days after the end of each calendar quarter, unaudited quarterly

normal year end adjustments and the absence of footnotes;

     (c) no later than 40 days after the end of each calendar month, monthly financial and
business reports, which shall consist of a profit and loss statement, balance sheet and
statement of cash flows and statement of Capital Accounts, as of the end of and for the
prior calendar month, which shall be prepared in accordance with GAAP except for normal year
end adjustments and the absence of footnotes;

-37-

 

     (d) weekly construction reports and monthly operating reports with respect to the
Haynesville Expansion Project reasonably acceptable to the Partners; and

     (e) such other information as a Partner may reasonably request.

     9.3 Bank Accounts. Funds of the Partnership shall be deposited in such banks or other
depositories as shall be designated from time to time by the Management Committee. All
withdrawals from any such depository shall be made only as authorized by the Management
Committee or the Management Company and shall be made only by check, wire transfer, debit
memorandum or other written instruction. The Partnership will have its own bank account and its
funds will not be commingled with those of any other Person.

     9.4 Confidentiality.

     (a) Each Partner agrees that all Confidential Information shall be kept confidential by
such Partner, shall only be used for the purpose of reviewing and evaluating the performance
of the Partnership and the Partner’s interest therein, and shall not be disclosed in any
manner, except to such of the Partner’s Authorized Representatives who have a need to know
and who agree to be, or are otherwise, bound by the Partner’s obligations hereunder and
except as otherwise expressly permitted in this Section 9.4. Each Partner shall be
responsible for any breach of this Section 9.4 by itself or any of its Authorized
Representatives, and each Partner covenants and agrees that it shall promptly notify the
Partnership of any actual, potential or threatened breach of this Section 9.4 and
shall, at its own expense, enforce, and assist the Partnership in its enforcement of, the
provisions of this Section 9.4, including, to the extent reasonably necessary,
seeking specific enforcement through court proceedings. Subject to Section 9.4(b),
if a Partner or any of its Authorized Representatives is requested or required by applicable
Law to disclose any Confidential Information, such Partner shall, to the maximum extent
permitted by applicable Law, provide the Partnership with prompt written notice thereof and
will use reasonable efforts to resist disclosure, until an appropriate protective order or
motion to quash may be sought or a waiver of compliance with this Section 9.4 may be
granted. If, in the absence of a protective order or the receipt of a waiver hereunder,
such Partner or any of its Authorized Representatives is, in the opinion of its legal
counsel, legally required to disclose Confidential Information, then such Partner or its
Authorized Representatives may disclose only that portion of the Confidential Information
legally required to be disclosed, without liability hereunder; provided, that such Partner
or its Authorized Representatives uses reasonable efforts to obtain reliable assurance that
confidential treatment will be accorded the Confidential Information. Each Partner
acknowledges and agrees that the Partnership and the other Partners may be irreparably
harmed by disclosure of the Confidential Information, that money damages would not be a
sufficient remedy for any breach of this Section 9.4 by such Partner or its
Authorized Representatives and that, in addition to any other remedies available at law or
in equity, specific performance and injunctive or other equitable remedies shall be
available to the Partnership and the Partners as a remedy for any such breach or threatened
breach, without the requirement of posting bond or other security. The Partnership and the
other Partners shall be entitled to recover their costs and expenses, including attorneys’
fees, incurred in connection with any successful action

-38-

 

brought by them to enforce the terms
of this Agreement. With respect to Confidential Information that is subject to
confidentiality agreements under any third-party confidentiality agreements, each Partner
covenants and agrees to, and shall cause its Authorized Representatives to, treat such
Confidential Information confidentially in accordance with, and to comply with the terms of,
the confidentiality provisions contained in those third-party confidentiality agreements
that have been disclosed to such Partner, including, any provisions thereof that impose more
stringent or additional
obligations than those set forth herein (provided, that such has been disclosed to such
Partner). The obligations of a Partner pursuant to this Section 9.4 shall continue
following the time such Person ceases to be a Partner, but thereafter such Person shall not
have the right to enforce the provisions hereof.

     (b) Notwithstanding anything to the contrary in this Agreement, each Partner may
disclose any information about the Partnership, including any Confidential Information,
without any liability to the Partnership or to any other Partner or to their respective
Affiliates and without any notice to any Partner, to the extent that such disclosing Partner
believes that such disclosure is necessary or appropriate to satisfy its (or its Affiliates)
public disclosure obligations under the Securities Act, the Exchange Act, the rules of any
stock exchange, or any similar public disclosure obligations; provided that such disclosing
Partner shall give each of the other Partners prior opportunity to review and comment on any
such disclosure to the extent such disclosure relates to any such other Partner or its
Affiliates.

     9.5 Conflicts of Interest.

     (a) Except as expressly provided in Section 9.5(b) and Section 9.5(c),
a Partner or an Affiliate of a Partner may engage in and possess interests in other business
ventures of any and every type and description, independently or with others, including ones
in competition with the Partnership and specifically including business ventures engaged in
the Partnership Business, with no obligation to offer to the Partnership, any other Partner
or any Affiliate of another Partner the right to participate therein. The Partnership may
transact business with any Partner or Affiliate of a Partner, subject to Sections
7.3(h) and (i). Without limiting the generality of the foregoing, the Partners
recognize and agree that the Partners and/or their respective Affiliates currently, or in
the future may, subject to Section 9.5(b) and Section 9.5(c), engage in
various activities similar or related to the Partnership Business (herein referred to as
“Outside Activities”). Subject to Section 9.5(b) and Section 9.5(c), no
Partner or Affiliate of a Partner shall be restricted in its right to conduct, individually
or jointly with others, for its own account any Outside Activities, and no Partner or its
Affiliates shall have any duty or obligation, express or implied, fiduciary or otherwise, to
account to, or to share the results or profits of such Outside Activities with, the
Partnership, any other Partner or any Affiliate of any other Partner, by reason of such
Outside Activities.

     (b) Notwithstanding anything to the contrary in Section 9.5(a), Regency HIG
hereby agrees to be bound by the terms and conditions of that certain AMI Agreement, dated
as of the Effective Date, by and among Regency Energy Partners LP, the Partnership and the
Alinda Investors (the “AMI Agreement”), and the Partners consent to

-39-

 

the Partnership
complying with its obligations under the AMI Agreement. For the avoidance of doubt, if the
Company elects not to pursue (or is deemed to have elected not to pursue) an AMI Opportunity
pursuant to the terms of the AMI Agreement, then Regency HIG (or any of its Affiliates)
shall have the right to pursue such AIM Opportunity independently of the Partnership and the
other Partners in accordance with the terms of the AMI Agreement.

     (c) Notwithstanding anything to the contrary in Section 9.5(a), each of the
Partners hereby acknowledges and agrees that no Partner (or any Affiliate of any Partner)
shall have the right to pursue or engage in any Partnership Specific Opportunity other than
through the Partnership.

     9.6 Haynesville Expense Reimbursement. In accordance with the terms of Article 2 of
the Contribution Agreement, the Partnership shall distribute to Regency HIG the Pre-Closing
Expenditures (as defined in the Contribution Agreement). For the avoidance of doubt, the Partners
hereby acknowledge and agree that, for all purposes, the agreed net fair market value of Regency
HIG’s Initial Capital Contribution (after giving effect to such distribution) is equal to
$400,000,000.

     9.7 Haynesville Expansion Cost Overruns. Regency HIG shall contribute to the
Partnership an amount equal to any Cost Overruns (as defined in the Contribution Agreement) in
accordance with Section 5.5 of the Contribution Agreement. Notwithstanding anything to the
contrary in this Agreement, the Partnership shall not issue Regency HIG any GP Units with respect
to any Capital Contributions made by Regency HIG pursuant to this Section 9.7.

     9.8 Financing. The Partners agree to use good faith and commercially reasonable
efforts to cause the Partnership to obtain, following the completion of the Haynesville Expansion
Project, financing on reasonable commercial terms in a principal amount of not less than three
times Consolidated EBITDA.

     9.9 Permitted Investments. Notwithstanding anything to the contrary in this
Agreement, the Partnership shall cause all cash Capital Contributions contributed to the
Partnership to be invested in Permitted Investments until such cash Capital Contributions are
expended by the Partnership in accordance with any Budget, distributed as Available Cash or as
otherwise approved by the Management Committee.

ARTICLE X

DISSOLUTION, LIQUIDATION, AND TERMINATION

     10.1 Dissolution. The Partnership shall dissolve and its affairs shall be wound up on
the first to occur of the following (each a “Dissolution Event”):

     (a) notice from the Management Committee to the Partners dissolving the Partnership;

     (b) entry of a decree of judicial dissolution of the Partnership under Section 15-801
of the Act;

-40-

 

     (c) the sale or abandonment of all or substantially all of the Partnership’s business
and assets; or

     (d) an event that makes it unlawful for all or substantially all of the business or
affairs of the Partnership to be carried on.

     10.2 Winding Up and Termination.

     (a) On the occurrence of a Dissolution Event, the Management Company (or such other
Person as may be designated by the Management Committee) shall serve as liquidator under the
supervision of the Management Committee. The liquidator shall proceed diligently to wind up
the affairs of the Partnership and to make final distributions as provided in this Agreement
and in the Act. The costs of winding up shall be borne as a Partnership expense. Until
final distribution, the liquidator shall continue to operate the Partnership’s properties
with all of the power and authority of the Partners. The steps to be accomplished by the
liquidator are as follows:

     (i) as promptly as possible after dissolution and again after final winding up,
the liquidator shall cause a proper accounting to be made by a recognized firm of
certified public accountants of the Partnership’s assets, liabilities and operations
through the last calendar day of the month in which the dissolution occurs or the
final winding up is completed, as applicable;

     (ii) the liquidator shall discharge from the Partnership’s funds all of the
indebtedness of the Partnership and other debts, liabilities and obligations of the
Partnership or otherwise make adequate provision for the payment and discharge
thereof (including the establishment of a cash escrow fund for contingent
liabilities in such amount and for such term as the liquidator may reasonably
determine); and

     (iii) all remaining assets of the Partnership shall be distributed to the
Partners as follows:

     (1) the liquidator may sell any or all the Partnership’s property,
including to Partners, and any resulting gain or loss from each sale shall
be computed and allocated to the Capital Accounts of the Partners in
accordance with the provisions of Section 6.2;

     (2) with respect to all Partnership property that has not been sold,
the Book Value of that property shall be determined and the Capital Accounts
of the Partners shall be adjusted to reflect the manner in which the
unrealized income, gain, loss and deduction inherent in such property that
has not previously been reflected in the Capital Accounts would be allocated
among the Partners as if there were a taxable disposition of that property
for the Book Value of that property on the date of distribution; and

-41-

 

     (3) Partnership property (including cash) shall be distributed among
the Partners in accordance with Section 6.1(b), and those
distributions shall be made by the end of the taxable year of the
Partnership during which the liquidation of the Partnership occurs (or, if
later, the 90th day after the date of the liquidation).

     (b) The distribution of cash or property to a Partner in accordance with the provisions
of this Section 10.2 constitutes a complete return to the Partner of its Capital
Contributions and a complete distribution to the Partner of its Partnership Interest
and all the Partner’s property. To the extent that a Partner returns funds to the
Partnership, it has no claim against any other Partner for those funds.

     (c) No dissolution or termination of the Partnership shall relieve a Partner from any
obligation to the extent such obligation has accrued as of the date of such dissolution or
termination. Upon such termination, all books and records of the Partnership shall be
furnished to the liquidator, which shall keep such books and records (subject to review by
any Person that was a Partner at the time of dissolution) for a period at least three years.
At such time as the liquidator no longer agrees to keep such books and records, it shall
offer the Persons who were Partners at the time of dissolution the opportunity to take over
such custody, shall deliver such books and records to such Persons if they elect to take
over such custody and may destroy such books and records if they do not so elect. Any such
custody by such Persons shall be on such terms as they may agree upon among themselves.

     10.3 Deficit Capital Accounts. No Partner will be required to pay to the Partnership,
to any other Partner or to any third party any deficit balance that may exist from time to time in
another Partner’s Capital Account.

     10.4 Statement of Dissolution. On completion of the distribution of Partnership
assets as provided in this Article X, the Partners (or such other Person or Persons as the
Act may require or permit) shall file a statement of dissolution with the Secretary of State of the
State of Delaware, cancel any other filings made pursuant to Section 2.5, and take such
other actions as may be necessary to terminate the existence of the Partnership. Upon the filing
of such statement of dissolution, the existence of the Partnership shall terminate (and the Term
shall end), except as may be otherwise provided by the Act or other applicable Law.

ARTICLE XI

EXCULPATION AND INDEMNIFICATION

     11.1 Exculpation.

     (a) No Management Person (solely in such individual’s capacity as a Management Person)
shall be liable to the Partnership or to any Partner for any claims, losses, expenses,
costs, obligations, liabilities, actions, suits, proceedings, judgments, or settlements,
fines, penalties, interests or other amounts (including attorneys’ fees) (whether civil,
criminal, administrative or investigative) (collectively, “Claims”) arising or resulting
from or relating to the performance of any of such Management Person’s

-42-

 

obligations or duties
under this Agreement in its capacity as a Management Person, or otherwise attributable to
any breach of duty owed by such Management Person (by virtue of being a Management Person)
to the Partnership or the Partners, except to the extent such Claims or breach of duty is
based upon such Management Person’s fraud, bad faith, gross negligence or willful
misconduct. Without limiting the generality of the foregoing, the doing of any act or the
failure to do any act by any Management Person, which shall not constitute fraud, bad faith,
gross negligence or willful misconduct, the effect of which may cause or result in loss or
damage to the
Partnership, shall not subject any Management Person to any liability. The Management
Persons do not, in any way, guarantee the return of the Partners’ Capital Contributions or a
profit for the Partners from the operations of the Partnership. No Management Person shall
be responsible to any Partners because of a loss of their investments or a loss in
operations, unless the loss shall have been the result of fraud, bad faith, gross negligence
or willful misconduct. For the avoidance of doubt, nothing in this Section 11.1
shall be deemed to be a limitation on the Partnership’s indemnification obligations pursuant
to the MSA.

     (b) In performing its obligations or duties under this Agreement, a Management Person
(solely in such individual’s capacity as a Management Person) shall be fully protected in
relying in good faith upon the records of the Partnership and upon such information,
opinions, reports or statements presented to the Partnership by any Person as to matters the
Management Person reasonably believes are within such other Person’s professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Partnership, including information, opinions, reports or statements as to the value and
amount of the assets, liabilities, Profits, Losses or Available Cash or any other facts
pertinent to the existence and amount of assets from which distributions to Partners might
properly be paid.

     11.2 Indemnification.

     (a) To the fullest extent permitted by applicable Law, the Partnership shall protect,
defend, indemnify and hold harmless each Covered Person from and against all Claims actually
and reasonably incurred arising from any and all pending or completed Claims (including
negligence, strict or absolute liability, liability in tort and liabilities arising out of
violation of Laws or regulatory requirements of any kind) in which any Covered Person may be
involved, or is threatened to be involved, as a party or otherwise, by reason of its status
as a Covered Person; provided, that no Covered Person shall be entitled to be indemnified
pursuant to this Section 11.2(a) (x) with respect to any criminal proceeding, if
such Covered Person had reasonable cause to believe its conduct was unlawful, (y) in respect
of any Claim arising from or related to such Covered Person’s fraud, bad faith, gross
negligence or willful misconduct or (z) with respect to any Claims by or in the name of the
Partnership in respect of any Claims as to which such Covered Person shall have been
adjudged to be liable to the Partnership unless and only to the extent that the Delaware
Court of Chancery, or other court of appropriate jurisdiction, shall determine upon
application that, despite the adjudication of liability but in view of all the circumstances
of the case, such Covered Person is fairly and reasonably entitled to indemnity of such
expenses which the Delaware Court of Chancery, or other court of appropriate jurisdiction,
shall deem proper. The termination of any action, suit or

-43-

 

proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not
create a presumption that the Covered Person acted in a manner contrary to that specified
above.

     (b) Any amendment, modification or repeal of this Section 11.2 or any provision
in this Section 11.2 shall be prospective only and shall not in any way affect the
rights of any Covered Person under this Section 11.2 as in effect immediately prior
to such amendment, modification or repeal with respect to matters occurring, in whole or
in part, prior to such amendment, modification or repeal, regardless of when claims relating
to such matters may arise or be asserted.

     (c) Any indemnification pursuant to this Section 11.2 shall be made only out of
the assets of the Partnership, it being agreed that the Partners shall not be personally
liable for such indemnification and shall have no obligation to contribute or loan any
monies or property to the Partnership to enable it to effectuate such indemnification.

     (d) In no event may a Covered Person subject any Partner to personal liability by
reason of the indemnification provisions set forth in this Agreement.

     (e) The provisions of this Section 11.2 are for the benefit of the Covered
Persons, their heirs, successors, assigns and administrators and shall not be deemed to
create any rights for the benefit of any other Persons.

     11.3 Indemnification Procedures.

     (a) Subject to the other provisions of this Article XI, in the event that any
action, suit, claim, demand or proceeding is commenced by a third party involving a Claim (a
“Third Party Claim”) in respect of any matter that, if true (without any responsibility for
independent investigation of the facts or law contained in such notice from the third
party), would be subject to indemnification by the Partnership under any provision of
Article XI to a Covered Person entitled to such indemnification (an “Indemnified
Party”), the Indemnified Party shall promptly deliver written notice to the Partnership of
such Third Party Claim describing in reasonable detail (i) the nature of the Third Party
Claim, (ii) if practicable, the Indemnified Party’s best estimate of the amount of Losses
attributable to the Third Party Claim, (iii) the basis of the Indemnified Party’s request
for indemnification under this Agreement and (iv) a copy of all papers served with respect
to such claim (if any) (the “Claim Notice”). Failure to timely provide such Claim Notice
shall not affect the right of the Indemnified Party’s indemnification hereunder, except to
the extent the Partnership is materially prejudiced by such delay or omission.

     (b) The Partnership shall have the right to take control of all aspects of the
investigation and defense of the Indemnified Party against such Third Party Claim, except
that the Indemnified Party’s consent shall be required with respect to taking control of any
investigation or defense (i) if the liabilities involved in such proceedings involve any
material risk of the sale, forfeiture, or loss of, or the creation of any lien or other
encumbrance on, any property of such Indemnified Party or (ii) which could entail

-44-

 

a risk of
criminal liability to any Indemnified Party. If the Partnership notifies the Indemnified
Party that the Partnership elects to assume the defense of the Third Party Claim within 30
days of such Partnership’s receipt of the Claim Notice (such election to be without
prejudice to the right of the Partnership to dispute whether such claim is an indemnifiable
Claim under this Article XI), then the Partnership shall have the right to defend
such Third Party Claim with counsel selected by the Partnership (who shall be reasonably
satisfactory to the Indemnified Party), by all appropriate proceedings, to a
final conclusion or settlement at the discretion of the Partnership in accordance with
this Section 11.3(b). The Partnership shall have full control of such
investigation, defense and proceedings, including any compromise or settlement thereof;
provided, that the Partnership shall not enter into any settlement agreement without the
written consent of the Indemnified Party (which consent shall not be unreasonably withheld,
conditioned or delayed); provided, further, that such consent shall not be required if (i)
the settlement agreement contains a complete and unconditional general release by the third
party asserting the Third Party Claim of all Indemnified Parties affected by the claim and
(ii) the settlement agreement does not contain any sanction or restriction upon the conduct
of any business by any Indemnified Party or its Affiliates; provided, further, that the
Partnership shall in no event, without the consent of the Indemnified Party, take or refrain
from taking any action that would reasonably be expected to materially impair the
indemnification of such Indemnified Party hereunder or would require such Indemnified Party
to take or refrain from taking any action or to make any public statement, which such Person
reasonably considers materially adversely affect its interests. If requested by the
Partnership, the Indemnified Party agrees to cooperate reasonably with the Partnership, at
the Partnership’s cost and expense, and its counsel in contesting any Third Party Claim
which the Partnership elects to contest, including the making of any related counterclaim
against the Person asserting the Third Party Claim or any cross complaint against any
Person. The Indemnified Party may participate in, but not control, any investigation,
defense or settlement of any Third Party Claim controlled by the Partnership pursuant to
this Section 11.3(b), and the Indemnified Party shall bear its own costs and
expenses with respect to such participation.

     (c) If the Partnership does not notify the Indemnified Party within 30 days of such
Partnership’s receipt of the Claim Notice that the Partnership elects to take control of the
investigation and defense of the Indemnified Party pursuant to Section 11.3(b), then
the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable
cost and expense (but only if the Indemnified Party is actually entitled to indemnification
hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified
Party, by all appropriate proceedings, which proceedings shall be prosecuted diligently by
the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such
Third Party Claim in good faith and have full control of such defense and proceedings;
provided, however, that the Indemnified Party may not enter into any compromise or
settlement of such Third Party Claim if indemnification is to be sought hereunder, without
the consent of the Partnership of such proposed settlement (which consent shall not be
unreasonably withheld, conditioned or delayed); provided, further, that such consent shall
not be required if (i) the settlement agreement contains a complete and unconditional
general release by the third party asserting the Third Party Claim of all Indemnified
Parties affected by the claim and (ii) the settlement agreement

-45-

 

does not contain any
sanction or restriction upon the conduct of any business by any Partnership or its
Affiliates. The Partnership may participate in, but not control, any defense or settlement
controlled by the Indemnified Party pursuant to this Section 11.3(c), and the
Partnership shall bear its own costs and expenses with respect to such participation.

     (d) Subject to the other provisions of this Article XI, a claim for
indemnification by any Indemnified Party for any matter not involving a Third Party Claim
shall be asserted by delivery of a Claim Notice to the Partnership promptly after such
Indemnified Party becomes aware of the facts or circumstances giving rise to such claim.

     11.4 Expenses. To the fullest extent permitted by applicable Law, if the Partnership
does not elect to take control of the investigation and defense of an Indemnified Party pursuant to
Section 11.3(b), reasonable expenses (including legal fees) incurred by such Indemnified
Party in defending any indemnified Third Party Claim pursuant to Section 11.3(c) shall,
from time to time, be advanced by the Partnership to such Indemnified Party at reasonable intervals
prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by
the Partnership of an undertaking by or on behalf of such Indemnified Party to repay such amount if
it shall be finally determined by a court of competent jurisdiction that such Indemnified Party is
not entitled to be indemnified as authorized in Section 11.2.

     11.5 Insurance. As of the Effective Date the Partnership will cause the Management
Company to provide insurance of the types, limits and coverages described on Exhibit G and
shall use commercially reasonable efforts to maintain such insurance after the Effective Date,
except to the extent the Management Committee decides to obtain and maintain other insurance (or
not maintain insurance). The Partnership may enter into indemnity contracts with Covered Persons
and such other Persons as the Management Committee shall determine and may adopt written procedures
pursuant to which arrangements are made for the advancement of expenses and the funding of
obligations under Section 11.3 and containing such other procedures regarding
indemnification as are appropriate.

     11.6 Acts Performed Outside the Scope of the Partnership. Each Partner (each Partner
in such capacity, an “Indemnitor”) shall indemnify, defend, save and hold harmless each other
Partner (an “Indemnitee”) from any and all Claims actually and reasonably incurred that shall or
may arise by virtue of any act or thing done or omitted to be done by the Indemnitor (directly or
through agents or employees) outside the scope of, or in breach of, the terms of this Agreement;
provided, however, that the Indemnitor shall be properly notified of the existence of the Claim,
and shall be given reasonable opportunity to cure any act or omission causing liability, and shall
be entitled to participate in the defense thereof. The Indemnitee’s failure to give such notice
shall not affect the Indemnitor’s obligations hereunder, except to the extent of any actual
prejudice arising therefrom.

     11.7 Attorneys’ Fees. All of the indemnities provided in this Agreement shall include
reasonable attorneys’ fees, including appellate attorneys’ fees and court costs.

-46-

 

     11.8 Subordination of Other Rights to Indemnity. The interests of the Partners (if
any) in any proceeds of the Partnership by way of repayment of loans, return of any Capital
Contributions, or any distributions from the Partnership, shall be subordinated to the right of
Partners to the indemnities provided by this Article XI.

     11.9 Survival of Indemnity Provisions. Except as otherwise specifically provided
herein, all of the indemnity provisions contained in this Agreement shall survive a Partner’s
ceasing to be a Partner hereunder.

     11.10 Reimbursement Obligation. Notwithstanding anything to the contrary in this
Agreement, if any Partner (a “Reimbursed Partner”) actually pays or incurs any liability of the
Partnership as a result of such Reimbursed Partner being jointly and severally liable for the
Partnership’s obligations by operation of Law or otherwise (other than any liability arising from
any breach of this Agreement by such Reimbursed Partner), then such Reimbursed Partner may deliver
a notice to each other Partner (each, a “Reimbursing Partner”) setting forth in reasonable detail
the nature of such liability and the costs actually paid or incurred by such Reimbursed Partner
(the “Reimbursable Costs”). Promptly after receipt of any such notice, each Reimbursing Partner
shall reimburse the Reimbursed Partner for such Reimbursing Partner’s pro rata share of the
Reimbursable Costs (based on the Partners’ respective Sharing Ratios at the time such Reimbursable
Costs are paid or incurred).

ARTICLE XII

REPRESENTATIONS, WARRANTIES AND COVENANTS

     12.1 Representations, Warranties and Covenants. Each Partner hereby severally (and
not jointly and severally) as to itself only represents, warrants and covenants to the Partnership
and the other Partners as follows:

     (a) The Partner understands that the purpose of the Partnership is to engage in the
Partnership Business. The Partner has read and is familiar with, and has been given full
and complete access to, information, financial or otherwise, regarding the Partnership and
has utilized such access to the Partner’s satisfaction and has obtained any other relevant
information the Partner has sought. The Partner has been given the opportunity to ask
questions of, and receive answers from, the Partnership concerning the terms and conditions
of, and other matters pertaining to, its purchase and ownership of the GP Units.

     (b) The Partner has read this Agreement and understands that the GP Units being
acquired by the Partner will be governed by the terms of this Agreement. The Partner agrees
to be bound, in all respects, by the terms of this Agreement.

     (c) The Partner has sufficient knowledge and experience in financial and business
matters to be capable of evaluating the merits and risks of acquiring and owning the GP
Units. The Partner is able to bear the economic risk of a total loss of the value of the GP
Units.

     (d) The Partner is acquiring the GP Units for its own account and not with a view to,
or for, resale in connection with any distribution thereof. The Partner

-47-

 

understands and
acknowledges that the GP Units are not securities and the sale of the GP Units has not been
registered under the Securities Act or under state securities laws. In addition, the
Partner acknowledges that the GP Units are subject to restrictions on
transferability in this Agreement that will make it difficult for the Partner to
Transfer the GP Units. The Partner further understands that any certificates representing
the GP Units may contain legends restricting the Transfer of the GP Units.

     (e) The Partner is fully authorized and qualified to become a Partner of the
Partnership and is authorized to make the Initial Capital Contribution to the Partnership,
and the person executing this Agreement on the Partner’s behalf has been duly authorized to
do so.

     (f) The Partner understands and acknowledges that (i) the Partnership may need to raise
additional capital from time to time in order to engage in the Partnership Business and
achieve any other objectives and goals that may be established for the Partnership by the
Management Committee, (ii) the Partnership may raise additional capital by selling GP Units
to one or more Partners or other Persons in accordance with the terms of this Agreement,
(iii) the Partner has no right to participate in any future offering, or to buy any
additional GP Units that may be issued, by the Partnership except to the extent set forth in
this Agreement, and (iv) the Partner’s Sharing Ratio in the Partnership may be diluted as a
result of any such sale of additional GP Units.

     (g) The Partner will indemnify and hold harmless the Partnership and its MC Members,
officers, Partners and Affiliates, and any other Person who controls or is controlled by any
of them, against any and all loss, liability, claim, damage and expense whatsoever,
including reasonable attorney’s fees, arising out of or based upon any false representation
or warranty or any breach by the Partner of any term or condition contained in this
Article XII.

     (h) All of the information provided to the Partnership by the Partner and all of the
Partner’s representations and warranties are true and correct as of the date of this
Agreement. The Partner’s representations, warranties and covenants shall survive the
delivery of the Partner’s Capital Contribution.

ARTICLE XIII

GENERAL PROVISIONS

     13.1 Offset. Whenever the Partnership is to pay any sum to any Partner or former
Partner, any amounts that a Partner or former Partner owes the Partnership may be deducted from
that sum before payment.

     13.2 Notices. Except as expressly set forth to the contrary in this Agreement, all
notices, requests or consents provided for or permitted to be given under this Agreement must be in
writing and must be delivered to the recipient in person, by courier or mail or by facsimile or
other electronic transmission. A notice, request or consent given under this Agreement is
effective on receipt by the Partner to receive it; provided, however, that a facsimile or other
electronic transmission that is transmitted after the normal business hours of the recipient shall

-48-

 

be deemed effective on the next Business Day. All notices, requests and consents to be sent to a
Partner must be sent to or made at the addresses given for that Partner on Schedule 1 or
such other address as that Partner may specify by notice to the other Partners. Any notice,
request or
consent to the Partnership must be given to all of the Partners. Whenever any notice is
required to be given by Law, the Certificate or this Agreement, a written waiver thereof, signed by
the Person entitled to notice, whether before or after the time stated therein, shall be deemed
equivalent to the giving of such notice.

     13.3 Entire Agreement. This Agreement and any other agreements expressly mentioned in
this Agreement constitute the entire agreement of the Partners and their respective Affiliates
relating to the Partnership and supersede all prior contracts or agreements with respect to the
Partnership, whether oral or written.

     13.4 Waivers. A waiver or consent, express or implied, to or of any breach or default
by any Person in the performance by that Person of its obligations with respect to the Partnership
is not a consent or waiver to or of any other breach or default in the performance by that Person
of the same or any other obligations of that Person with respect to the Partnership. Failure on
the part of a Person to complain of any act of any Person or to declare any Person in default with
respect to the Partnership, irrespective of how long that failure continues, does not constitute a
waiver by that Person of its rights with respect to that default until the applicable
statute-of-limitations period has run.

     13.5 Amendment or Restatement. Except as expressly set forth herein, this Agreement
(including the Exhibits and Schedules) may be amended or restated only by a written instrument
adopted, executed and agreed to by all of the Partners. The Certificate may be amended or restated
only with the approval of all of the Partners.

     13.6 Binding Effect. This Agreement shall be binding upon and inure to the benefit of
the Partners and their respective heirs, legal representatives, successors and assigns.

     13.7 Governing Law; Jurisdiction. THIS AGREEMENT IS GOVERNED BY AND SHALL BE
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE
OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF
ANOTHER JURISDICTION. A PARTNER AND THE PARTNERSHIP MAY BRING AN ACTION ARISING UNDER OR RELATING
TO THIS AGREEMENT, IF AT ALL, ONLY IN A FEDERAL OR STATE COURT OF COMPETENT JURISDICTION IN
WILMINGTON, DELAWARE. EACH PARTNER HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT
LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON-CONVENIENCE,
WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF SUCH ACTION OR PROCEEDING IN ANY SUCH
RESPECTIVE JURISDICTION.

     13.8 Severability. In the event of a direct conflict between the provisions of this
Agreement and any mandatory, non-waivable provision of the Act, such provision of the Act shall
control. If any provision of the Act provides that it may be varied or superseded in a

-49-

 

partnership
agreement (or otherwise by agreement of the partners of a partnership), that provision shall be
deemed superseded and waived in its entirety if this Agreement contains a provision addressing the
same issue or subject matter. If any provision of this Agreement or the
application thereof to any Partner or circumstance is held invalid or unenforceable to any
extent, (a) the remainder of this Agreement and the application of that provision to other Partners
or circumstances is not affected thereby, and (b) the Partners shall negotiate in good faith to
replace that provision with a new provision that is valid and enforceable and that puts the
Partners in substantially the same economic, business and legal position as they would have been in
if the original provision had been valid and enforceable.

     13.9 Tax Disclosure Authorization. Notwithstanding anything herein to the contrary,
the Partners (and each Affiliate and Person acting on behalf of any Partner) agree that each
Partner (and each employee, representative, and other agent of such Partner) may disclose to any
and all Persons, without limitation of any kind, the transaction’s tax treatment and tax structure
(as such terms are used in Sections 6011 and 6112 of the Code and the Treasury Regulations
thereunder) contemplated by this Agreement and all materials of any kind (including opinions or
other tax analyses) provided to such Partner or such Person relating to such tax treatment and tax
structure, except to the extent necessary to comply with any applicable federal or state securities
laws.

     13.10 Further Assurances. In connection with this Agreement and the transactions
contemplated hereby, each Partner shall execute and deliver any additional documents and
instruments and perform any additional acts that may be necessary or appropriate to effectuate and
perform the provisions of this Agreement and those transactions.

     13.11 Waiver of Certain Rights. Each Partner irrevocably waives any right it may have
to maintain any action for dissolution of the Partnership or for partition of the property of the
Partnership.

     13.12 No Third Party Beneficiary. Except as provided in Section 11.2(e) or
otherwise explicitly set forth in this Agreement, nothing contained in this Agreement is intended,
or shall be deemed, to benefit any third party or creditor of the Partnership.

     13.13 Counterparts. This Agreement may be executed in multiple counterparts
(including facsimile counterparts), each of which, when executed, shall be deemed an original, and
all of which shall constitute but one and the same instrument.

     13.14 Reliance on Counsel. Each of the Partners agrees that it has been represented
by independent counsel of its choice during the negotiation and execution of this Agreement and
that it has executed the same upon the advice of such independent counsel. Each Partner and its
counsel cooperated in the drafting and preparation of this Agreement and the documents referred to
herein, and any and all drafts relating thereto shall be deemed the work product of the Partners
and may not be construed against any Partner by reason of its preparation. Therefore, the Partners
waive the application of any Law or rule of construction providing that ambiguities in an agreement
or other document will be construed against the party drafting such agreement or document.

EXHIBIT C

HAYNESVILLE EXPANSION PROJECT

The Haynesville Expansion Project is an expansion of the existing pipeline system indirectly owned
by the Partnership that is located in North Louisiana. The project is expected to add 128 miles of
pipeline to the existing pipeline system. Specifically, the Bienville Loop Pipeline will add 28
miles of pipeline, the Elm Grove Pipeline will add 23 miles of pipeline and the Winnsboro Loop
Pipeline will add 77 miles of pipeline. The additional pipeline will range in diameter from 36 to
42 inches with the Bienville Loop and the Elm Grove Pipeline each expected to have a diameter of 36
inches and with the Winnsboro Pipeline expected to have a diameter of 42 inches. The project is
expected to add approximately 14,200 horsepower of compression at the Elm Grove and Haughton
Stations and approximately 1.1 Bcf/d of capacity to the existing pipeline system. The project is
expected to be completed in one phase by the end of the first quarter of 2010. The estimated total
cost of construction of the project is $653 million.

EXHIBIT D

TRANSFER RIGHTS

     Capitalized terms used in this Exhibit D that are not defined in this Exhibit shall
have the meanings given to them in the Amended and Restated General Partnership Agreement to which
this Exhibit D is attached. Unless the context requires otherwise, all references in this
Exhibit to Sections refer to the Sections of this Exhibit.

1. General Rules.

(a) No Partner may Transfer all or any portion of its GP Units other than in accordance with the
terms of this Exhibit D, and any attempted Transfer that is not in accordance with this
Exhibit D shall be, and is hereby declared, null and void ab initio.

(b) No Partner shall Transfer all or any of his or its GP Units or permit an indirect transfer of
GP Units if such Transfer or indirect transfer would (i) subject the Partnership to the reporting
requirements of the Exchange Act, (ii) subject the Partnership to the registration requirements,
under the Securities Act or any applicable state securities law or violate any applicable Laws
regulating the transfer of securities, (iii) cause the Partnership to be deemed to be an
“investment company” under the Investment Company Act, (iv) cause the Partnership to lose its
status as a partnership for federal income tax purposes or cause the Partnership to be classified
as a “publicly traded partnership” within the meaning of Code Section 7704 or (v) be in violation
of any Law relating to terrorism or money laundering, including Executive Order No. 13224 on
Terrorist Financing, effective Sept. 24, 2001 and the Uniting and Strengthening America by
Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, Public Law
107-56.

(c) The Partners agree that a breach of the provisions of this Exhibit D may cause
irreparable injury to the Partnership and the Partners for which monetary damages (or other
remedies at law) are inadequate in view of (i) the complexities and uncertainties in measuring the
actual damages that would be sustained by reason of the failure of a Person to comply with such
provisions and (ii) the uniqueness of the Partnership’s business and the relationship among the
Partners. Accordingly, the Partners agree that the provisions of this Exhibit D may be
enforced by specific performance.

2. Transfer Restrictions.

(a) No Partner may Transfer (other than pursuant to a Permitted Transfer) a portion of its GP Units
that is less than 5% of all of the issued and outstanding GP Units; provided, that if a Partner
owns less than 5% of all the issued and outstanding GP Units, such Partner may Transfer all (but
not less than all) of its GP Units, subject to, and in accordance with, the other provisions of
this Exhibit D.

(b) No Partner may Transfer (other than pursuant to a Permitted Transfer) all or any portion of its
GP Units to any Person for any type of consideration other than cash, cash equivalents or readily
marketable securities, without the prior written consent of each of the other Partners in their
Sole Discretion.

D-1

 

(c) Subject to the other provisions of this Exhibit D (including the right of first offer
set forth in Section 3 of this Exhibit D), prior to the third anniversary of the
Effective Date, no Partner may Transfer (other than pursuant to a Permitted Transfer or pursuant to
Transfer in connection with the foreclosure (or in lieu of foreclosure) of any pledge,
hypothecation, or encumbrance of any GP Units for security purposes) all or any portion of its GP
Units without the prior written consent of each of the other Partners in their Sole Discretion.

(d) Subject to the other provisions of this Exhibit D (including the right of first offer
set forth in Section 3 of this Exhibit D), at any time on or after the third
anniversary of the Effective Date, a Partner may Transfer all or any portion of its GP Units to any
Person without the consent of the Partnership or any other Partner.

3. Right of First Offer.

(a) If any Partner desires to Transfer all or any portion of its GP Units to any Person (other than
pursuant to a Permitted Transfer) or is subject to a demand or request to Transfer all or any
portion of its GP Units to any Person in connection with the foreclosure (or in lieu of
foreclosure) of any pledge, hypothecation, or encumbrance of its GP Units, then such Partner (the
"Disposing Partner”) shall promptly give written notice (a “Disposition Notice”) to the other
Partners (such other Partners, the “ROFO Partners”) that such Disposing Partner desires to effect
such a Transfer and setting forth the portion of GP Units proposed to be transferred by the
Disposing Partner (the “Sale GP Units”), the amount of consideration that such Disposing Partner
proposes to be paid for such Sale GP Units (the “Sale Price”) and any other material terms sought
by the Disposing Partner. The delivery of a Disposition Notice shall constitute an offer by the
Disposing Partner to sell to the ROFO Partners the Sale GP Units at the Sale Price in accordance
with the terms of this Section 3.

(b) Upon receipt of the Disposition Notice, each ROFO Partner may exercise the right of first offer
with respect to all or any portion of the Sale GP Units by delivering a written notice to the
Disposing Partner and the other ROFO Partners within 20 Business Days after the receipt of the ROFO
Partners Notice (such 20-Business Day period being referred to herein as the “ROFO Partners
Election Period”) setting forth the amount of the Sale GP Units such ROFO Partner is electing to
purchase, up to its pro rata share (based on the relative Sharing Ratios of the ROFO Partners as of
the date of such determination) plus any additional portion of the Sale GP Units it desires to
purchase in excess of its pro rata share (the “ROFO Over-Allotment Amount”) if other ROFO Partners
do not exercise all or any portion of their rights hereunder. The right of each ROFO Partner to
purchase Sale GP Units in excess of its pro rata share shall be based on the relative Sharing
Ratios of the ROFO Partners desiring to purchase ROFO Over-Allotment Amounts (or in such other
manner as all of the ROFO Partners who elect to exercise the right of first offer (the “Exercising
ROFO Partners”) agree to allocate the right to purchase among themselves).

(c) The closing of the purchase and sale of the Sale GP Units to the Exercising ROFO Partners shall
occur no later than the 20th Business Day following the end of the ROFO Partners Election Period
unless the Exercising ROFO Partners and the Disposing Partner otherwise agree
in writing. At the closing, each of the Exercising ROFO Partners shall deliver to the Disposing
Partner cash (by wire transfer in immediately available funds) in the amount of the Sale Price

D-2

 

applicable to the Sale GP Units to be purchased by such Exercising ROFO Partner, and the Disposing
Partner shall represent and warrant to each of the Exercising ROFO Partners pursuant to a written
agreement delivered at such closing that the Disposing Partner owns such Sale GP Units free and
clear of all liens, encumbrances and adverse claims, and shall deliver to each of the Exercising
ROFO Partners, as applicable, executed transfer instruments as are deemed reasonably necessary by
the Management Committee for the proper transfer of such Sale GP Units on the books of the
Partnership. The Disposing Partner and the Exercising ROFO Partners shall cooperate in good faith
in obtaining all necessary governmental and other third Person approvals, waivers and consents
required for the closing. Notwithstanding the foregoing, any such closing shall be delayed, to the
extent required, to obtain any necessary governmental approvals, waivers and consents required for
the closing (including any approvals under the HSR Act); provided, that if such approval, waiver or
consent is required by any Exercising ROFO Partner to consummate such closing and such approval,
waiver or consent is not obtained within 40 Business Days following the end of the ROFO Partners
Election Period, then the Exercising ROFO Partners shall be deemed to have rejected the offer to
purchase any of the Sale GP Units and no Exercising ROFO Partner shall be deemed to have breached
any obligation to purchase any portion of the Sale GP Units.

(d) If the ROFO Partners fail to notify the Disposing Partner prior to the expiration of the ROFO
Partners Election Period of their election to acquire all of the Sale GP Units pursuant to any
Disposition Notice, then the ROFO Partners shall be deemed to have rejected the offer to purchase
any of the Sale GP Units. If the ROFO Partners are deemed to have rejected the offer to purchase
any of the Sale GP Units, the Disposing Partner shall be free to Transfer all of the Sale GP Units
to any Person during the 90-Business Day period following the expiration of the ROFO Partners
Election Period; provided, that the consideration and other terms offered by the Disposing Partner
shall be no more favorable to the transferee taken as a whole than those offered in the Disposition
Notice. If the consideration constituting the Sale Price includes any readily marketable
securities, then, for purposes of this Section 3, the cash value of such readily marketable
securities shall be deemed to be an amount equal to (i) in the case of securities that are
primarily traded on a National Securities Exchange (other than The Nasdaq Stock Market, Inc.), the
average of their last sale prices, regular way, as reported in the principal consolidated
transaction reporting system of such National Securities Exchange on each trading day during the 21
trading-day period ending immediately prior to the date of the determination, or if no sales
occurred on any such day, the mean between the closing “bid” and “asked” prices on such day and
(ii) if the principal market for such securities is, or is deemed to be, in the over-the-counter
market or The Nasdaq Stock Market, Inc., the average of their closing sale prices on each trading
day or, if not so quoted, the mean between their closing “bid” and “asked” prices on such day
during the 21 trading-day period ending immediately prior to the date of the determination, as
published by The Nasdaq Stock Market, Inc., in the case of securities primarily traded on The
Nasdaq Stock Market, Inc., or the FINRA/NASDAQ Trade Reporting Facility or such other system then
in use, in the case of a principal market that is the over-the-counter market, or if such price is
not so published on any such day, the mean between their closing “bid” and “asked” prices, if
available, on any such day, which prices may be obtained from any professional market maker making
a market in such securities, or any reputable pricing service, broker or dealer. For purposes of
this Section 3, “National Securities Exchange” means an exchange registered with the United
States Securities and Exchange Commission under Section 6(a) of the Securities

D-3

 

Exchange Act, and
any successor to such statute. Any Sale GP Unit not sold during such 90-Business Day period shall
be subject again to right of first offer set forth in this Section 3.

4. Co-Sale (Tag-Along) Rights.

(a) The remaining provisions of this Section 4 shall not apply to a Permitted Transfer.

(b) If any Partner (the “Co-Sale Seller”) desires to Transfer all or a portion of its GP Units that
is equal to or greater than 20% of the GP Units held by such Co-Sale Partner (the “Proposed Co-Sale
Transfer”), then such Co-Sale Seller shall offer (the “Co-Sale Offer”) to include in the Proposed
Co-Sale Transfer the GP Units owned and designated by any other Partner on the same terms as the
Co-Sale Seller, in each case, according to the remaining terms of this Section 4.

(c) The Co-Sale Seller shall give written notice to each other Partner (the “Co-Sale Notice”) at
least 20 Business Days prior to the scheduled closing of the Proposed Co-Sale Transfer or, if
earlier, on the date any applicable purchase agreement is signed. The Co-Sale Notice shall specify
the proposed transferee (the “Co-Sale Buyer”), the GP Units proposed to be Transferred as part of
the Proposed Co-Sale Transfer, the amount and type of consideration to be received therefor and the
place and date on which the Transfer is to be consummated and shall include a complete and accurate
copy of the applicable purchase agreement.

(d) If a Partner (a “Co-Sale Electing Partner”) wishes to accept the Co-Sale Offer and participate
in the Proposed Co-Sale Transfer, such Co-Sale Electing Partner must notify the Co-Sale Seller no
later than ten Business Days following the date the Co-Sale Seller gives the Co-Sale Notice. Each
Co-Sale Electing Partner may, unless otherwise agreed by each other Co-Sale Electing Partner and
the Co-Sale Seller, elect to Transfer to the Co-Sale Buyer a portion of such Co-Sale Electing
Partner’s GP Units up to an amount equal to the product of (i) the aggregate number of GP Units
that the Co-Sale Buyer desires to purchase, multiplied by (ii) a fraction, the numerator of which
shall be the number of GP Units held by such Co-Sale Electing Partner and the denominator of which
shall be the aggregate number of GP Units held by all of the Co-Sale Electing Partners and the
Co-Sale Seller. The number of GP Units that may be sold by the Co-Sale Seller to the Co-Sale Buyer
shall be reduced by the aggregate number of GP Units that the Co-Sale Electing Partners elect to
Transfer hereunder. Each Co-Sale Electing Partner shall participate in the Proposed Co-Sale
Transfer upon the same terms and conditions as the Co-Sale Seller. The closing date of the
Proposed Co-Sale Transfer will be the date specified in the Co-Sale Notice. Notwithstanding the
foregoing, such closing date shall be delayed, to the extent required, to obtain any necessary
governmental approvals, waivers and consents required for the closing (including any approvals
under the HSR Act); provided, that if such approval, waiver or consent is required by any Co-Sale
Electing Partner to consummate such closing and such approval, waiver or consent is not obtained
within 40 Business Days after the closing date set forth in the Co-Sale Notice, then such Co-Sale
Electing Partner shall be deemed to have rejected the offer to participate in the Proposed Co-Sale
Transfer and such Co-Sale Electing Partner shall not be deemed to have breached any obligation to
participate in such Proposed Co-Sale Transfer.

5. Dispositions of Upper Tier Entities.

D-4

 

(a) If at any time an Indirect Transfer occurs with respect to any Partner (any such Partner, a
"Transferred Partner”), then, as of the date of such Indirect Transfer, such Transferred Partner
shall be deemed to have offered to each other Partner the right to purchase all of such Transferred
Partner’s GP Units (the “Indirect Transfer GP Units”) for an amount equal to the FMV (or with
respect to an Indirect Transfer that occurs prior to the third anniversary of the Effective Date
(other than an Indirect Transfer occurring prior to the third anniversary of the Effective Date as
a result of the foreclosure (or in lieu of foreclosure) of any pledge, hypothecation, or
encumbrance of any interests in any Person that Controls such Transferred Partner), 90% of the FMV)
of such Indirect Transfer GP Units (the “Indirect Transfer Sale Price”). The Transferred Partner
shall notify the Partnership in writing of any such Indirect Transfer promptly after the occurrence
thereof. The Partnership shall promptly notify each Partner after it receives notice of any such
Indirect Transfer (the “Indirect Transfer Notice”). Each other Partner shall have the right, but
not the obligation, to purchase the Indirect Transfer GP Units pursuant to the following terms:

(i) Upon receipt of the Indirect Transfer Notice, each non-Transferred Partner may exercise
the right of first offer with respect to all or any portion of the Indirect Transfer GP
Units by delivering a written notice to the Transferred Partner and the Partnership and the
other non-Transferred Partners within ten Business Days after the receipt of such notice
(such ten-Business Day period being referred to herein as the “Indirect Transfer Election
Period”) setting forth the amount of such Indirect Transfer GP Units such non-Transferred
Partner is electing to purchase (the “Indirect Transfer Participating Partner”), up to its
pro rata share (based on the relative Sharing Ratios of the non-Transferred Partners as of
the date of such Indirect Transfer) plus any additional portion of such Indirect Transfer GP
Units it desires to purchase in excess of its pro rata share (the “Indirect Transfer
Over-Allotment Amount”) if the other non-Transferred Partners do not exercise all or any
portion of their rights hereunder. The right of each Indirect Transfer Participating
Partner to purchase Indirect Transfer GP Units in excess of its pro rata share shall be
based on the relative Sharing Ratios of the Indirect Transfer Participating Partners
desiring to purchase Indirect Transfer Over-Allotment Amounts (or in such other manner as
all of the Indirect Transfer Participating Partners agree to allocate the right to purchase
among themselves).

(ii) If the non-Transferred Partners fail to notify the Transferred Partner and the
Partnership prior to the expiration of the Indirect Transfer Election Period of their
election to acquire all of the Indirect Transfer GP Units, then the other Partners shall be
deemed to have rejected the offer to purchase any of the Indirect Transfer GP Units, and the
Management Committee shall designate reasonably and in good faith the new Ultimate Parent of
such Transferred Partner.

D-5

 

(iii) The closing of the purchase and sale of the Indirect Transfer GP Units shall occur no
later than the 20th Business Day following the end of the Indirect Transfer Election Period
unless the Transferred Partner and each of the Indirect Transfer Participating Partners
otherwise agree in writing. At the closing, each Indirect Transfer Participating Partner
shall deliver to the Transferred Partner cash (by wire transfer in immediately available
funds) in the amount of the Indirect Transfer Sale Price applicable to the Indirect Transfer
GP Units to be purchased by such Indirect Transfer Participating Partner, and the
Transferred Partner shall represent and warrant to each of the Indirect Transfer
Participating Partners pursuant to a written instrument to be delivered at such closing that
the Transferred Partner owns such Indirect Transfer GP Units free and clear of all liens,
encumbrances and adverse claims, and shall deliver to each of the Indirect Transfer
Participating Partners, as applicable, executed transfer instruments as are deemed
reasonably necessary by the Management Committee for the proper transfer of such Indirect
Transfer GP Units on the books of the Partnership. The Transferred Partner and the other
Partners shall cooperate in good faith in obtaining all necessary governmental and other
third Person approvals, waivers and consents required for the closing. Notwithstanding the
foregoing, any such closing shall be delayed, to the extent required, to obtain any
necessary governmental approvals, waivers and consents required for the closing (including
any approvals under the HSR Act); provided, that if any such approval, waiver or consent is
required by any Indirect Transfer Participating Partner to consummate such closing and such
approval, waiver or consent is not obtained within 40 Business Day following the end of the
Indirect Transfer Election Period, as applicable, then the non-Transferred Partners shall be
deemed to have rejected the offer to purchase any of the Indirect Transfer GP Units and no
non-Transferred Partner shall be deemed to have breached any obligation to purchase any
Indirect Transfer GP Units.

(b) Each Partner hereby makes, constitutes and appoints the Partnership as its true and lawful
attorney-in-fact for it and in its name, place, and stead and for its use and benefit, to sign,
execute, certify, acknowledge, swear to, file and record any instrument that is now or may
hereafter be deemed necessary by the Partnership in its reasonable discretion to carry out fully
the provisions and the agreements, obligations and covenants of such Partner in this Section
5 if such Partner is deemed to be a Transferred Partner. Each Partner hereby gives such
attorney-in-fact full power and authority to do and perform each and every act or thing whatsoever
requisite or advisable to be done in connection with such Partner’s obligations and agreements
pursuant to this Section 5 as fully as such Partner might or could do personally, and
hereby ratifies and confirms all that any such attorney-in-fact shall lawfully do or cause to be
done by virtue of the power of attorney granted hereby. The power of attorney granted pursuant to
this Section 5(b) is a special power of attorney, coupled with an interest, and is
irrevocable, and shall survive the bankruptcy, insolvency, dissolution or cessation of existence of
the applicable Partner.

6. Conditions to Transfers.

(a) As a condition to any Transfer permitted under the Agreement (including Permitted Transfers),
any transferee of GP Units shall be required to become a party to the Agreement by executing an
adoption agreement in the form attached as Annex 1 to this Exhibit D (an “Adoption
Agreement”). If any Person acquires GP Units from a Partner in a Transfer, notwithstanding such
Person’s failure to execute an Adoption Agreement
in accordance with the preceding sentence (whether such Transfer resulted by operation of law or
otherwise), such Person and such GP Units shall be subject to the Agreement as if such GP Units
were still held by the transferor.

(b) No GP Units may be Transferred by a Person unless the transferee first delivers to the
Partnership, at the transferring Partner’s sole cost and expense, evidence reasonably satisfactory
to the Partnership (such as an opinion of counsel) to the effect that such Transfer is not required

D-6

 

to be registered under the Securities Act; provided, that the Partnership, with the approval of the
Management Committee, may waive the requirements of this Section 6(b).

7. Cooperation. Subject to the other terms of this Exhibit D, if any Partner with
a Sharing Ratio of more than 10% (or in the case of the Alinda Investors only, a combined Sharing
Ratio of more than 10%) desires to Transfer (and is permitted to do so in accordance with terms of
the Agreement and this Exhibit D) any GP Units held thereby, at the request thereof, the
Partnership and the subsidiaries will cooperate in all reasonable respects to assist such Partner
with such proposed Transfer, which cooperation will include the Partnership and the subsidiaries’
furnishing the proposed transferee information, including confidential information, about the
Partnership and the subsidiaries and making the Partnership’s and the Subsidiaries’ executive
personnel and site managers available to answer questions; provided, the Partnership and the
subsidiaries shall not be required to furnish confidential information to the proposed transferee
until the proposed transferee has entered into a customary non-disclosure agreement in form
satisfactory to the Partnership. The requesting Partner shall reimburse the Partnership for its
reasonable out-of-pocket expenses incurred in connection with the cooperation provided by the
Partnership pursuant to this Section 7.

8. Regulatory Requirements. Notwithstanding anything else set forth herein to the
contrary, in the event of any reasonable determination in good faith by a Partner that, by reason
of any existing or future Law or any other federal or state rule, regulation, guideline, order,
request or directive (whether or not having the force of law and whether or not failure to comply
therewith would be unlawful) (collectively, a “Regulatory Requirement”), such Partner is
effectively restricted or prohibited from holding any of the GP Units then held by such Partner,
the Partnership and the other Partners shall use reasonable good faith efforts to take such action
as they may determine is reasonably necessary and appropriate to permit such Partner to transfer
the GP Units to an Affiliate to comply with such Regulatory Requirement. All such actions shall be
taken at the expense of such Partner. The Partner shall give written notice to the Partnership of
any reasonable determination by it hereunder and the transfer it believes may be necessary or
appropriate to permit it to comply with such Regulatory Requirement.

9. Fair Market Value. For purposes of this Exhibit D, “FMV” means, with respect to
any GP Units redeemed or Transferred pursuant to Section 5 as a result of an Indirect
Transfer, the fair market value of such GP Units as determined (in accordance with this Section
9) by an independent appraiser of nationally recognized standing selected by the Management
Committee (provided, that any MC Member designated by the applicable Transferred Partner shall not
be entitled to participate in any decision by the Management Committee to select such appraiser);
provided, however, that if the applicable Indirect Transfer occurred as a result of a bona fide
arms’ length transaction transfer, sale or assignment of all of the interests in a Person
whose principal assets were the applicable GP Units and the only consideration paid for such
interests was cash or cash equivalents, then the aggregate FMV of the applicable GP Units shall be
the amount of consideration paid for such interests pursuant to such transfer, sale or assignment.
The independent appraiser selected by the Management Committee shall determine the FMV of any GP
Units in accordance with the following principles: (i) fair market value shall mean the price at
which the GP Units being redeemed or Transferred would change hands between a willing buyer and
willing seller, neither being under any compulsion and both having reasonable knowledge of the
relevant facts and (ii) the presence or absence of voting or control rights and

D-7

 

any other relevant
discounts shall be considered. The FMV of any GP Units shall be determined as of whichever of the
following dates results in the lowest FMV for such GP Units: (x) the date of the applicable
Indirect Transfer or (y) the date the Partnership first receives written notice from the applicable
Transferred Partner of the applicable Indirect Transfer.

Services) provided by the Management Company, including insurance premiums
payable in connection with insurance required to be obtained and maintained
pursuant to Section 2.5, Section 2.10 and Schedule 2.5
attached hereto (collectively, “Third Party Expenses”), then the Owner shall
reimburse the Management Company for all Third Party Expenses, to the extent

that are attributable to the Assets (or the construction, operation,
maintenance or management thereof) as determined by the Parties on an equitable
basis.

	 	(b)	 	Amounts Payable to Management Company Personnel. In
consideration for the O&M Services, the Construction Management Services and

Project Budget, including the following costs and expenses (collectively, the

the Regency GP, LLC Long-Term Incentive Plan, shall be reimbursed to

costs.

	 	 	 	The Owner’s pro rata share of Reimbursable Personnel Expenses with respect
to each individual providing Services shall be based on a fraction, the
numerator of which is the number of hours in the pay periods ending during
the preceding calendar month such individual devoted to matters relating to
the Assets and the denominator of which is the aggregate number of hours
such individual devoted to all work performed in the pay periods ending in
the preceding calendar month. Where it is not reasonably practicable to
determine the pro rata share of Reimbursable Personnel Expenses with respect
to an individual, the Management Company shall make a good faith reasonable
estimate of such pro rata share.

     3.3 Adjustment of Payments.

     (a) If after the Effective Date (x) the Owner completes any acquisitions or dispositions of
assets or businesses or undertakes any Development Project (other than the Haynesville Expansion
Project), (y) any new Laws or accounting rules are enacted or implemented or (z) any other change
in the business of the Owner occurs that is not anticipated as of the Effective Date, then the G&A
Payment shall be equitably increased or decreased, as appropriate, in order to account for
adjustments in the nature and extent of the G&A Services to be provided by the Management Company
to the Owner, with any such increase or decrease in the G&A Payment to be determined in good faith
negotiations between the Parties at such time.

     (b) In the event that the Owner requests additional Services pursuant to Section 2.6
and the Parties agree on the amount of the adjustment to the G&A Payment and/or Reimbursable
Personnel Expenses payable to the Management Company with respect to such

12

 

     additional Services (which agreement is a condition to the Management Company providing such
additional Services), then the G&A Payment and/or the Reimbursable Personnel Expenses payable to
the Management Company shall be adjusted to reflect such agreement.

	 	(a)	 	No later than ten (10) days following the end of each calendar
month following the Effective Date, the Management Company will submit monthly
invoices to the Owner for the Third Party Expenses and Reimbursable Personnel
Expenses incurred by the Management Company during such calendar month.

days following the end of each calendar month following the Effective Date.

available funds, to an account designated by the Management Company from time

interest shall accrue on any unpaid amount at the Interest Rate calculated from
the date due until the date paid. In the event an amount charged by the
Management Company and paid by the Owner is later found to be more than the
amount actually due, the Management Company shall refund the overpayment,
together with interest at the Interest Rate calculated from the date of payment
until the date of refund.

     3.5 Taxes. In addition to other amounts owed pursuant to this Agreement, the Owner
shall be responsible for, and shall pay, all taxes applicable to (i) the provision of the Services
by the Management Company (whether or not such taxes increase or decrease in the future), and (ii)
the ownership, operation, maintenance or control of the Assets. The Management Company may add to
its invoices the amount of such taxes which the Management Company pays pursuant to the terms of
this Agreement, or is otherwise required by applicable Law, to pay directly to the relevant taxing
authority in connection with this Agreement, and such amounts shall be due with such invoices.
Notwithstanding anything to the contrary contained herein, each Party shall be responsible for (i)
income taxes resulting from amounts paid or payable to it under this Agreement, and (ii) employment
taxes and social security payments relating to its own employees. For the avoidance of doubt, the

if the effect thereof would be to cause such Party to be in violation of any applicable Law.

not give rise to any right of recourse against any current or former stockholder, member, partner,
owner, director, manager, officer or employee of the Management Company (including any current or
former member of the Senior Management Team) or of the Owner or any of their respective officers,
directors, employees, agents or representatives.

account and such other records as are necessary to reflect the results of operation of the Owner,
such books and records to be maintained at the offices of the Owner (it being agreed that the
Management Company may keep its own books and records related to the performance of this Agreement

otherwise reasonably directed by the Owner. All of such books and records shall be and remain at

extent that the Management Company shall be required to retain such copies in accordance with
applicable Laws) shall be turned over to the Owner forthwith so as to ensure the orderly
continuance of the operation of the Owner.

applicable to the Services and invoices set forth herein during normal business hours at the

subsequent to termination of this Agreement (including payment obligations arising prior to such
termination, dispute resolution procedures, or indemnities in respect of events or situations
existing prior to such termination) shall survive such termination and continue in full force and
effect for the limited purposes set forth therein.

     9.19 Mutuality of Drafting. The Parties hereby stipulate and agree that each of them
fully participated and was adequately represented by counsel in the negotiation and preparation of
this Agreement and the Parties further stipulate and agree that in the event of an ambiguity or
other necessity for interpretation to be made of the content of this Agreement, this Agreement
shall not be construed in favor of or against the Owner or the Management Company as a consequence
of one Party having had a greater role in the preparation of this Agreement, but shall be construed
as if the language were mutually drafted by both Parties with full assistance of counsel.
