and obligations with respect to the Company.

     NOW, THEREFORE, for and in consideration of the mutual covenants contained herein, and other
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
Members hereby agree as follows, intending to be legally bound:

     (b) The Company’s existence shall be perpetual, unless and until it is dissolved in accordance
with Article XI.

     Section 1.2 Purpose of the Company; Powers. The Company has been formed for the
purpose of engaging in the Business. The Company has the power to do any and all acts necessary,
appropriate, proper, advisable, incidental or convenient to, or in furtherance of, the Business.

ARTICLE II

RESPONSIBILITIES OF THE MEMBERS

     Section 2.1 Responsibilities of the Members. Subject to Article III, each
Member and its Affiliates may engage, directly or indirectly, without the consent or approval of
the other Member or the Company, in the business conducted by such Member and its Affiliates as of
the Effective Date and in any other business, business opportunities, transactions, ventures or
other arrangements of any nature or description, independently or with others, including business
of a nature that may be competitive with or the same as or similar to the business conducted by the
Company, regardless of the geographic location of such business, all without any duty or obligation
to account to the other Member or the Company in connection therewith. Nothing herein is intended
to create a partnership, joint venture, agency or other relationship creating fiduciary or
quasi-fiduciary duties or similar duties and obligations (except as otherwise expressly provided by
this Agreement or by Law) or subject either Member to joint and several or vicarious liability or
to impose any duty, obligation or liability that would arise therefrom with respect to either or
both of the Members or the Company. To the extent that, at law or in equity, either Member (or its
Director) has any fiduciary or other duty to the Company or the other Member pursuant to this
Agreement, such duty is hereby eliminated to the maximum extent permitted pursuant to section
18-1101(c) of the Act. Notwithstanding anything to the contrary in this Agreement, (a) each Member
(through its Director) shall be permitted to vote its Membership Interest in its own self-interest
and (b) subject to Article III, (i) the doctrine of corporate opportunity, or any analogous
doctrine, shall not apply to either Member, (ii) neither Member that (directly or through an
Affiliate controlled by such Member) acquires knowledge of a potential transaction, agreement,
arrangement or other matter that may be an opportunity for the Company shall have any duty to
communicate or offer such opportunity to the Company or the other Member, and such Member shall not
be liable to the Company, to the other Member or any other Person for breach of any fiduciary or
other duty by reason of the fact that such Member pursues or acquires such opportunity or
information, and (iii) neither the Company nor either Member shall have any right, by virtue of
this Agreement, to share or participate in such other businesses, investments or activities of a
Member or to the income or proceeds derived therefrom.

     Section 2.2 Representations and Warranties. Each Member hereby represents and warrants
to the Company and the other Member that (a) it is duly formed, validly existing and in good
standing under the Laws of the state of its

formation, and, if required by Law, is duly qualified to do business and is in good standing
in each jurisdiction in which it conducts any of its business, (b) it has full corporate, limited
liability company, partnership (limited or general), trust, or other applicable power and authority
to execute and deliver this Agreement and to perform its obligations hereunder and all necessary
actions by the board of directors, stockholders, managers, members, partners, trustees,
beneficiaries, or other Persons necessary for the due authorization, execution, delivery and
performance of this Agreement by such Member have been duly taken or received, as applicable, (c)
it has duly executed and delivered this Agreement, and this Agreement is a legally binding
obligation of such Member, enforceable against such Member in accordance with its terms, subject to
applicable bankruptcy, moratorium,

5

 

insolvency and other applicable Laws generally affecting
creditors’ rights and general principles of equity (whether applied in an Action in a court of law
or equity), (d) its authorization, execution, delivery and performance of this Agreement does not
conflict with any material obligation under any material agreement or arrangement to which such
Member is a party or by which it is (or any of its assets are) bound, (e) it (i) has been furnished
with such information about the Company and the Membership Interests as such Member has requested,
(ii) has made its own independent inquiry and investigation into, and based thereon has formed an
independent judgment concerning, the Company and the Membership Interests, (iii) has adequate means
of providing for its current needs and possible contingencies, is able to bear the economic risks
of an investment in the Company (and the Membership Interests) and has a sufficient net worth to
sustain a loss of its entire investment in the Company (and the Membership Interests), and (iv) is
an “accredited investor” within the meaning of “accredited investor” under Regulation D of the
Securities Act, and (f) it understands and agrees that its Membership Interest shall not be
Transferred (including by being made the subject of a Lien), and that it shall not be the subject
of a Change of Control, except in accordance with the terms of this Agreement and, in the case of
any Transfer of its Membership Interest, pursuant to an applicable exemption from registration
under the Securities Act and other applicable securities Laws.

     Section 2.3 Intrastate Covenants.

     (a) Each Member will use (and shall cause its Restricted Persons to use) all commercially
reasonable efforts to ensure that it does not (and that its Restricted Persons do not) take any
action or fail to take any action where the action or failure to act would cause (i) the Pipeline
(or any portion thereof) to transport NGLs in interstate commerce so as to cause the Pipeline (or
any portion thereof) to become a common carrier subject to the jurisdiction of the FERC under the
Interstate Commerce Act, as amended, 49 USC App. §§1-65a (the “ICA”) or (ii) the facilities of
either Member (if such facilities are connected or related to the Pipeline (or any portion thereof)
in such a manner that the jurisdictional status of such facilities affects the jurisdictional
status of the Pipeline (or any portion thereof)) to become subject to the jurisdiction of the
Federal Energy Regulatory Commission (such regulatory agency or any successor regulatory agency,
“FERC”) under the ICA. THE OPERATOR AGREES TO INDEMNIFY, DEFEND AND HOLD HARMLESS THE NON-OPERATOR
INDEMNIFIED PARTIES FROM ANY AND ALL CLAIMS OF ANY CHARACTER WHATSOEVER RESULTING FROM THE WILLFUL
AND KNOWING FAILURE, OR FAILURE BECAUSE OF GROSS NEGLIGENCE, OF THE OPERATOR TO COMPLY WITH THE
PROVISIONS OF THIS
SECTION 2.3(a). THE NON-OPERATING MEMBER AGREES TO INDEMNIFY, DEFEND AND HOLD
HARMLESS THE OPERATOR INDEMNIFIED PARTIES, FROM ANY AND ALL CLAIMS OF ANY CHARACTER WHATSOEVER
RESULTING FROM THE WILLFUL AND KNOWING FAILURE, OR FAILURE BECAUSE OF GROSS NEGLIGENCE, OF THE
NON-OPERATING MEMBER TO COMPLY WITH THE PROVISIONS OF THIS SECTION 2.3(a).

     (b) Except as expressly provided herein, no NGLs received or delivered on the Pipeline shall
be produced, transported, stored, used, consumed or sold in interstate commerce in a manner that
would cause (i) the Pipeline (or any portion thereof) to cease to constitute an intrastate NGL
pipeline system or (ii) the facilities of either Member (if such facilities are connected or
related to the Pipeline (or any portion thereof) in such a manner that the

6

 

jurisdictional status of
such facilities affects the jurisdictional status of the Pipeline (or any portion thereof)) to
become subject to the jurisdiction of FERC under the ICA.

     Section 2.4 No State Law Partnership; Liability to Third Parties.

     (a) The Members intend that the Company shall be a limited liability company and, without
limiting the provisions of Section 6.3 and Articles IX and X with respect
to United States federal income tax treatment (and other tax treatment consistent therewith), the
Company shall not be a state law partnership (including a limited partnership) or joint venture and
neither Member shall be a state law partner or joint venturer of the other Member, for any
purposes, and this Agreement may not be construed to suggest otherwise.

     (b) Neither Member (including the Operator in its capacity as a Member or in its capacity as
the Operator) shall be liable for the debts, obligations or liabilities of the Company solely by
reason of being a Member (or the Operator).

     Section 2.5 No Power to Bind Company or Other Member. Neither Member nor any of its
Affiliates may take any action purporting to bind the Company, the other Member or the other
Member’s Affiliates, except as provided in this Agreement. All actions undertaken by the Members
and their respective Affiliates, or any of them, are at their sole risk and expense except (a) for
actions undertaken by (or at the direction of) the Operator on behalf of the Company within the
scope of its authority under this Agreement and (b) to the extent, if any, that the Company (or the
Operator acting on behalf of the Company) expressly assumes the obligations arising from such
actions in accordance with this Agreement. Neither Member (nor any of its Affiliates) is an agent,
employee, contractor, vendor, representative or (except for tax purposes) partner of the other
Member or its Affiliates by virtue of its execution of this Agreement, and neither Member (nor any
of its Affiliates) may hold itself out as such; provided, however, that the Operator may act on
behalf of the Company as provided in this Agreement.

     Section 2.6 Default. Upon the occurrence (and during the continuance of) a Default with respect to either Member,
the other Member and the Company shall each be entitled (in addition to the specific rights and
remedies that such Member and the Company may have with respect to such Default pursuant to the
terms and provisions of this Agreement or at law or in equity) to take such action (including
instigating court Actions) as they may deem necessary or appropriate with respect to such Default.

     Section 2.7 Loss of Rights During Default. Notwithstanding anything to the contrary
set forth herein (including, for the avoidance of doubt, the definition of Unanimous Consent),
while a Member is in Default, such Member shall not be permitted to consent to, vote (directly or
through its Director) or otherwise participate in or make any decisions with respect to any action
(or inaction) to be taken by (or on behalf of) the Company, and the other Member shall have the
sole right to consent to, vote (directly or through its Director) and otherwise participate in or
make any decisions with respect to such action (or inaction) to be taken by (or on behalf of) the
Company.

     Section 2.8 Ownership. Title to Company assets, whether tangible, intangible, real,
personal or mixed, shall be deemed to be owned by the Company as an entity, and neither

7

 

Member
shall individually have any direct ownership in Company assets. Title to any and all of the Company
assets shall be held in the name of the Company. All Company assets shall be recorded as the
property of the Company in its books and records. The Company’s credit and assets shall be used
solely for the benefit of the Company, and no asset of the Company shall be transferred or
encumbered for, or in payment of, any individual obligation of either Member (including the
Operator).

     Section 2.9 Confidentiality.

     (a) The Members acknowledge that from time to time they may receive information from or
regarding the other Member or its Affiliates or their customers in the nature of trade secrets or
secret or proprietary information or information that is otherwise confidential, the release of
which may be damaging to the other Member, its Affiliates, or Persons with which they do business.
Each Member shall hold in strict confidence, and shall not use (other than in connection with the
Business), any such information it receives for a period of two years after the initial disclosure
thereof to such Member, and during such period, such Member may not disclose such information to
any Person other than its Affiliates and its and their employees, officers, directors, agents or
advisors (including attorneys, accountants, consultants, bankers, financial advisors and financing
entities) with which such Member has an executed confidentiality agreement or that are otherwise
subject to confidentiality obligations no less stringent than those set forth herein, in each case
who have a need to know such information, and the other Member.

     (b) The restrictions in Section 2.9(a) shall not apply to:

          (i) information which enters the public domain other than by breach of this Agreement;

          (ii) information already in the possession of a Member or any of its Affiliates before
disclosure to it pursuant to this Agreement, which was not acquired directly or indirectly from the
Member that was the source of such information (or any of its Affiliates) and which is not the
subject of a confidentiality agreement in favor of the source of such information;

          (iii) information lawfully obtained from a third party that is free to disclose such
information;

          (iv) information developed or created by a Member or any of its Affiliates independent of this
Agreement;

          (v) information required to be disclosed by a Member or any of its Affiliates to a third party
contemplating purchasing the Membership Interest or Equity Interests of such Member in order to
permit such third party to decide whether or not to proceed with the purchase and what price to
offer; provided that such third party shall have, prior to any such disclosure, entered into a
confidentiality agreement with such Member or its Affiliate on terms no less strict than the terms
of this Section 2.9 and such Member shall be liable for any further disclosure by such
third party in breach of this Agreement;

8

 

          (vi) information requested by any Governmental Entity entitled by Law to require the same;
provided that prior to such disclosure, the disclosing Member (or its Affiliate) shall notify in
writing the Member (or Affiliate of a Member) with respect to which such information relates that
such request has been made and shall reasonably cooperate with such Member (or Affiliate of a
Member) (at such Person’s request and expense) to obtain a protective order, confidential treatment
or other remedy (and, in the absence of such remedy, the disclosing Member (or its Affiliate) may
disclose only such portion of the subject information as advised by its counsel that it is legally
required to disclose); and

          (vii) information that a Member or its Affiliate must disclose under applicable securities
Laws or stock exchange regulations; provided that prior to such disclosure, the disclosing Member
(or its Affiliate) shall notify in writing the other Member (or Affiliate of such other Member)
with respect to which such information relates that the disclosing Member (or its Affiliate)
believes such disclosure is required and, in any event, the disclosing Member (or its Affiliate)
may disclose only such portion of the subject information that upon advice of counsel it is legally
required to disclose.

     (c) Any Member or its Affiliate seeking to rely on an exemption set forth in Section
2.9(b) shall provide such evidence as the Member (or Affiliate of a Member) with respect to
which such information relates may reasonably request to prove that the information sought to be
exempted from the requirements set forth in Section 2.9(a) satisfies an exemption set forth
in Section 2.9(b).

     Section 2.10 Publicity.

     (a) Neither Member will issue, or permit any agent or Affiliate of it to issue, any press
releases or otherwise make, or cause any agent or Affiliate of it to make, any public statements or
other public disclosures with respect to this Agreement or any of the instruments, documents and
agreements entered into pursuant to, or in connection with, this Agreement, or any of the
activities contemplated hereby (or thereby), unless not less than twelve (12) hours prior to so
releasing or disclosing any such information, the releasing or disclosing Member shall provide a
copy of the portion of the release, statement or disclosure containing such information to the
other Member; provided, however, that such requirement to provide copies shall not apply (i) where
such release, statement or disclosure is deemed in good faith by the releasing or disclosing Member
to be required by applicable Law or under the rules and regulations of a recognized stock exchange
on which any Equity Interests of such Member (or any of its Affiliates) are listed, so long as
prior to making any such release, statement or disclosure, the releasing or disclosing Member
provides a copy of the portion of the release, statement or disclosure containing such information
to the other Member and (ii) with respect to any regular disclosures by the Operator regarding
general business and operational matters disclosed by the Operator on a regular basis in the
ordinary course of business.

     (b) Notwithstanding anything to the contrary in this Section 2.10 or Section
2.9, in the event of any emergency endangering property, human life or the environment, the
Operator may issue such press releases or public announcements as it deems necessary in light of
the circumstances and shall promptly provide the other Member with a copy of any such press release
or announcement.

     Section 2.11 Affiliate Contracts; Matters Involving Affiliates.

     (a) The Members acknowledge that the Company may from time to time enter into contracts with a
Member or an Affiliate of a Member (any such contract, an “Affiliate Contract”). In addition to the
provisions set forth in Section 4.8(e), with respect to each Affiliate Contract, (i) the
negotiation of each Affiliate Contract shall be conducted on behalf of the Company by or under the
direction of the Director appointed by Member that is not, or whose Affiliates are not, to be a
party to such Affiliate Contract, and (ii) all decisions and actions concerning such Affiliate
Contract, other than those made with respect to matters arising in the ordinary course of business,
shall be approved and authorized by the Director appointed by the Member that is not, and whose
Affiliates are not, a party to such Affiliate Contract at the time such decision is being made or
action is being taken.

     (b) In the case of any decision or action with respect to any Action involving the Company as
a party to which a Member, or an Affiliate of a Member, is a party materially adverse to the
Company (other than as a co-defendant or the equivalent), such decision or action shall be approved
and authorized by the Director appointed by the Member that is not (and whose Affiliates are not) a
party materially adverse to the Company (other than as a co-defendant or the equivalent).

Section 2.12 Limitation of Liability; Indemnification

     (a) Limitation of Liability. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS
AGREEMENT, THE MEMBERS AND THE COMPANY EXPRESSLY AGREE THAT THE OPERATOR SHALL NOT BE LIABLE TO THE
NON-OPERATOR INDEMNIFIED PARTIES, THE NON-OPERATING MEMBER SHALL NOT BE LIABLE TO THE OPERATOR
INDEMNIFIED PARTIES, AND THE COMPANY SHALL NOT BE LIABLE TO ANY PERSON (INCLUDING THE NON-OPERATOR
INDEMNIFIED PARTIES AND THE OPERATOR INDEMNIFIED PARTIES), FOR ANY EXEMPLARY, PUNITIVE, INDIRECT,
CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES; PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATIONS
SHALL NOT APPLY TO DAMAGES PAYABLE (I) PURSUANT TO SECTION 2.3 OR (II) WITH RESPECT TO

Texas 77580, as an area of mutual interest (the “Area of Mutual Interest”) with respect to the
storage and fractionation of NGLs, liquefied petroleum gases and refined petroleum products (the
“AMI Products”). Subject to the provisions of applicable Law and except as otherwise permitted by
the terms of this Agreement, neither Member, nor any Affiliate of such Member, shall engage in, or
acquire any equity interest in or provide any debt financing to any Person engaged or who proposes
to engage in, the business of the storage or fractionation of any AMI Products within the Area of
Mutual Interest, except that either Member may acquire up to a 20% equity interest in, or provide
up to 20% of the aggregate debt financing for, a Person engaged or who proposes to engage in the
business of the storage or fractionation of any AMI Products within the Area of Mutual Interest.

11

 

     Section 3.2 Expansion Projects.

     (a) If either Member becomes aware of an opportunity to develop, plan, design, engineer,
procure, construct, install or acquire (i) any expansion of capacity of the assets of the Company
as of the date hereof, (ii) an AMI Product storage or fractionation facility within the Area of
Mutual Interest or (iii) any capital project referred to in Section 6.13 of the Purchase Agreement
(each, an “Expansion Project”), that such Member desires to have the Company pursue, then (A) such
Member shall prepare a written presentation setting forth (1) the projected revenue, capital costs
and operating costs for such Expansion Project, (2) the proposed Capital Contributions to be made
by the Members to fund such Expansion Project, (3) any external debt financing proposed to be
pursued in connection with such Expansion Project, including the proposed interest rate, maturity
and other terms of such debt financing and (4) any other relevant information such as legal,

at least five (5) business days prior to any meeting of the
Company Board called for the purpose of considering such Expansion Project and (C) the Company
Board shall consider such Expansion Project at a meeting called for such purpose (provided that the
Proposed Expansion Project Presentation has been delivered to the other Member in accordance with
the preceding clause (B)). If the Company Board approves, by Unanimous Consent, the pursuit of the
Expansion Project and the Capital Contributions, in each case as set forth in the Proposed
Expansion Project Presentation or as otherwise approved by the Company Board by Unanimous Consent
(an “Approved Project”), then the Company Board shall instruct the Operator to proceed with such
Approved Project in accordance with and on the terms so approved by the Company Board (the
“Approved Project Plan”).

     (b) If the Company Board, at its next meeting, does not approve by Unanimous Consent the
pursuit of an Expansion Project proposed by a Member in accordance with Section 3.2(a),
then the proposing Member may either (i) pursue such Expansion Project for its own account outside
the Company, and neither the Company nor the non-proposing Member shall have any interest or right
to participate in such Expansion Project, or (ii) require the Company to pursue such Expansion
Project (any such Expansion Project, a “Mandated Project”) in accordance with and on the terms
proposed by the proposing Member (the “Mandated Project Plan”); provided that in the case of this
clause (ii), the proposing Member may require the Company to pursue such Mandated Project only if:

          (A) such Mandated Project has a projected positive net present value of distributable cash
flow for the first ten (10) years following its proposed in-service date, calculated using (1) the
projected revenue, capital costs, operating expenses, specified in the Proposed Expansion Project
Presentation and (2) a discount rate equal to the sum of (I) the arithmetic average of (x) the
weighted average annual interest on senior, long-term indebtedness of the non-proposing Member
outstanding at the time the Proposed Expansion Project Presentation is delivered by the proposing
Member to the non-proposing Member pursuant to Section 3.2(a) and (y) the average Cost of
Incremental Equity Capital with respect to the Common Units of the non-proposing Member at the time
the Proposed Expansion Project Presentation is delivered by the proposing Member to the

12

 

          (B) if the Mandated Project relates to an expansion of the capacity of the Pipeline or other
intrastate NGL pipeline through looping and/or the addition of compression, (1) the Mandated
Project is supported by one or more shippers who meet the Credit Standards and who have executed
written, binding commitments for not less than fifty percent (50%) of the firm capacity of such
Mandated Project for not less than five (5) years and (2) the portion of the Pipeline or other
pipeline to which the Mandated Project relates lacks sufficient available firm capacity to
accommodate such creditworthy shipper(s).

     Section 3.3 Inapplicability of Certain Article III Provisions. Notwithstanding
anything to the contrary set forth in this Article III, while either Member is in Default,
such Member shall not be permitted to cause the Company to undertake any Mandated Project pursuant
to Section 3.2(b)(ii).

ARTICLE IV

MANAGEMENT OF THE COMPANY

     Section 4.1 Management of the Company.

     (a) The management of the Company is fully vested in the Members, acting exclusively in their
Member capacities; provided, however, that the Board and the Operator shall have the respective
power and authority described in this Article IV in addition to any authority expressly
granted to the Operator elsewhere in this Agreement. The Operator shall constitute a “manager,” as
the term is used in the Act, and no employee or agent of the Company or the Non-Operating Member
shall constitute “managers.” Decisions or actions taken by the Operator in accordance with the
provisions of this Agreement shall constitute decisions or actions by the Company and shall be
binding on each Member and the Company.

     (b) Any Person dealing with the Company, other than a Member or a Member’s Affiliate, may rely
on the authority of the Operator or the Company Board in taking any action in the name of the
Company without inquiry into the provisions of this Agreement or compliance with it, regardless of
whether such action actually is taken in compliance with the provisions of this Agreement. Except
as otherwise expressly provided in this Agreement, each Member hereby (i) specifically delegates to
the Operator and the Company Board its rights and powers to manage and control the business and
affairs of the Company in accordance with the provisions of Section 18-407 of the Act, and (ii)
waives its right to bind the Company, as contemplated by the provisions of Section 18-402 of the
Act.

     (c) Subject to the limitations set forth below and except as otherwise expressly provided in
this Agreement, including any requirement for Unanimous Consent of the Company Board (it being
understood and agreed that in the event of any inconsistency between this Section 4.1(c)
and any other provision of this Agreement, such other express provision shall control), the
Operator shall have the exclusive right and full authority to manage, conduct and control the
Business consistent with the purposes of the Company, including the power and authority to do the
following with respect to and on behalf of the Company:

13

 

          (i) enter into equipment leases and incur or contract for purchase money indebtedness or other
liabilities in the ordinary course of business or as otherwise permitted by this Agreement;

          (ii) make tax (consistent with Section 6.3 and Articles IX and X),
regulatory and other filings, and render periodic or other reports to Governmental Entities having
jurisdiction over the Business or assets of the Company;

          (iii) make any expenditures and use the assets of the Company (including cash on hand) for any
purpose consistent with the terms of this Agreement;

          (iv) negotiate, enter into, obtain, administer, maintain, amend, supplement, modify, waive and
otherwise perform, any contract, conveyance or other instrument (including any permits and licenses
to which the Company is a party);

          (v) make cash distributions to the Members in accordance with the provisions of Section
9.4;

          (vi) select, engage and dismiss employees and agents, outside attorneys, accountants,
engineers, consultants and contractors and determine their compensation and the other terms of
their employment or hiring;

          (vii) maintain (or caused to be maintained) the Company Insurance in accordance with
Section 4.1(i);

          (viii) sell, exchange, transfer, lease or dispose of any Company assets;

          (ix) control any matters affecting the rights and obligations of the Company, including the
commencement, prosecution and defense of Actions at law or in equity, and otherwise engage in the
conduct of litigation, incur legal expense and settle any Claims or any Actions;

          (x) indemnify any Person against any Claims to the extent permitted by applicable Law;

          (xi) perform any services or activities necessary or incidental to the development and
construction of any Approved Project or Mandated Project, including coordinating, managing,
monitoring and causing the successful implementation of the Approved Project Plan with respect to
any Approved Project and the Mandated Project Plan with respect to any Mandated Project;

          (xii) take any actions necessary or appropriate in the case of an emergency or otherwise to
conduct and maintain the Company’s operations and properties (including any Approved Projects and
Mandated Projects) in a safe and efficient manner in accordance with industry practice;

          (xiii) amend this Agreement pursuant to Section 12.5(a); and

14

 

          (xiv) otherwise conduct any activities necessary or appropriate for the conduct and
furtherance of the Business.

     (d) In the performance of its obligations under this Agreement as the Operator, the Operator
shall act as a reasonable and prudent operator and in compliance with applicable Law; provided,
however, that notwithstanding the foregoing or anything else in this Agreement to the contrary, the
Operator shall only be liable to the Non-Operator Indemnified Parties for Damages suffered by such
Persons as a result of, caused by, or arising out of any breach by the Operator of the foregoing
obligations (including the Operator’s interpretation or application of any Laws) to the extent of
any proceeds under any Company Insurance received with respect to such Damages, unless (and then
only to the extent that) such breach results from the Operator’s gross negligence or willful
misconduct, in which case the Operator shall also be liable to the Non-Operator Indemnified Parties
for any liability with respect to such Damages that is not covered by the Company Insurance
(including any deductible payable under such Company Insurance with respect to such Damages).

     (e) The Operator may only be removed “for cause.” If the Non-Operating Member believes that a
“for cause” event has occurred, it may deliver written notice to the Operator (a “Notice of Cause
for Removal”), which notice shall specify in reasonable detail the “for cause” event that the
Non-Operating Member believes has occurred, within thirty (30) days after the alleged occurrence of
such “for cause” event, it being understood and agreed that any failure to deliver a Notice of
Cause for Removal within thirty (30) days after the alleged occurrence of a “for cause” event shall
be deemed to be a release and waiver by the Non-Operating Member with respect to such “for cause”
event. If the Operator does not dispute by written notice the alleged occurrence of a “for cause”
event (a “Removal Dispute Notice”) within thirty (30) days after its receipt of the Notice of Cause
for Removal, the removal of the Operator shall be effective ninety (90) days after such receipt.
If the Operator wishes to dispute the alleged occurrence of a “for cause” event, is shall deliver a
Removal Dispute Notice to the Non-Operating Member within thirty (30) days after its receipt of the
Notice of Cause for Removal. Upon receipt of such Removal Dispute Notice, the Members shall
negotiate in good faith to find a mutually agreeable resolution of the disputed removal. If the
Members are unable to resolve such disputed removal within thirty (30) days of the receipt of the
Removal Dispute Notice, the Members shall submit such dispute to arbitration in accordance with
Section 4.10. For purposes of this Section 4.1(d), “for cause” means (i) the
Operator’s being in Default for a period of thirty (30) days (or such longer period as may be
required to cure such Default if the Operator is diligently pursuing a cure with respect to such
Default) after the delivery of written notice of such Default by the Non-Operating Member to the
Operator, (ii) the occurrence of a Change of Control with respect to the Operator, (iii) the
occurrence of a merger or other combination by the Operator’s Ultimate Parent with, or the sale of
all or substantially all of the assets of the Operator’s Ultimate Parent to, an non-Affiliate or
(iv) a Transfer (other than a Transfer to an Affiliate or a bona fide pledge pursuant to
Section 8.2) of one hundred percent (100%) of the Operator’s Membership Interest. Upon the
removal of the Operator, the Non-Operating Member shall assume the role of Operator.

     (f) The Operator may resign from its position as Operator by delivering ninety (90) days’
prior written notice (a “Notice of Resignation”) to the Non-Operating Member. On the
effective date set forth in any Notice of Resignation, the Non-Operating Member shall assume
the role of Operator; provided, however, that at the request of the Non-Operating Member, the

15

 

Operator that has resigned (unless the resignation of the Operator is made in connection with the
Operator’s Transfer of one hundred percent (100%) of its Membership Interest) shall continue to
serve as Operator in compliance with the provisions of this Agreement for a transition period of up
to one hundred fifty (150) days following the delivery of the Notice of Resignation.

     (g) Prior to the effectiveness of any removal or resignation of the Operator, the Operator
shall deliver all books and records of the Company in its possession to the Non-Operating Member.
The Non-Operating Member that replaces the Operator in accordance with the provisions of this
Section 4.1 shall act as the Operator in accordance with the terms and provisions of this
Agreement (including the then applicable Annual Budget).

     (h) Notwithstanding anything to the contrary herein, the Operator shall have no obligation
under the terms of this Agreement to take any action or make any expenditures that would require
spending any amount that the Non-Operating Member has failed to fund in Default, or in excess of
amounts the Operator is permitted to spend in accordance with any approved Annual Budget, plus a
variance of fifteen percent (15%), on an aggregate basis, or otherwise in accordance with the
provisions of this Agreement. The Operator further shall have no liability for any failure to take
any such action or make any such expenditures.

     (i) The Operator shall obtain and maintain (or cause to be obtained and maintained) on behalf
of the Company, insurance coverage for the Company and its assets and properties that it determines
is necessary or appropriate in connection with the conduct of the Business (the “Company
Insurance”). Each Member will obtain and maintain (or cause one of its Affiliates to obtain and
maintain) insurance covering its respective officers, directors and employees arising from their
actions as members of the Company Board or otherwise on behalf of the Company. The costs reasonably
allocated to any Company Insurance, including applicable deductibles and self-insured retentions,
obtained and maintained on behalf of the Company by the Operator’s making available for the benefit
of the Company the insurance of any of its Affiliates, shall be reimbursed to the Operator by the
Company.

     (j) In the event of Operator being rendered unable, wholly or in part, by Force Majeure to
carry out its obligations under this Agreement, except payment of money, it is agreed that upon the
Operator giving notice and reasonably full particulars of such Force Majeure within a reasonable
time after the occurrence of the cause relied on, then the obligations of the Operator giving such
notice, so far as it is affected by such Force Majeure, shall be suspended during the continuance
of any inability so caused, but for no longer period, and such cause shall so far as possible be
remedied with all reasonable dispatch. In such event, the Company shall be entitled to take such
action as it deems reasonable to exercise the duties and responsibilities of the Operator during
the pendency of such Force Majeure.

     Section 4.2 Company Board.A Company Board of Directors (the “Company Board”) shall be established by the Company. The
purpose of the Company Board shall be to consider and approve or disapprove the Unanimous Consent
Decisions and any other matters specifically identified in this
Agreement as requiring Unanimous Consent. To the extent not included as a Unanimous Consent
Decision or specifically identified in this Agreement as a matter requiring Unanimous Consent, all
decisions regarding the management of the business and affairs of the Company shall be made by the
Operator.

16

 

     Section 4.3 Company Board Composition; Initial Directors. The Company Board shall consist of two Directors. Each Member shall be entitled to appoint
one Director; provided, however, that either Member shall lose its right to appoint a Director if,
and for so long as, its Percentage Interest is less than twenty percent (20%), and the Director
appointed by such Member shall be removed and replaced at the option of the other Member by a
Director of the other Member’s choosing. The initial Directors are set forth on Schedule 1
hereto. Each Director appointed to the Company Board shall serve until his or her successor is duly
appointed or until his or her earlier death, removal or resignation.

     Section 4.4 Removal and Replacement of Directors. Each Member shall have the right, at any time and for any reason (or for no reason), to
remove its Director. Should any Director be unwilling or unable to continue to serve, or otherwise
cease to serve (including by reason of his or her involuntary removal), then the Member that
appointed such Director shall be entitled fill the resulting vacancy on the Company Board.

     Section 4.5 Meetings of the Company Board.

     (a) Meetings of the Company Board shall be held at the request of either Member on at least
five business days’ prior notice.

     (b) Directors may participate in and hold a meeting of the Company Board by means of
conference telephone, videoconference equipment or similar communications equipment by which all
Persons participating in the meeting can hear each other, and participation in such manner in any
such meeting constitutes presence in person at such meeting.

     (c) The Director appointed by the Member serving as the Operator, if present, shall preside at
all meetings of the Company Board.

     (d) Each Director shall have the full authority to act on behalf of the Member that appointed
such Director. The action of a Director at a meeting (or through a written consent) of the Company
Board shall bind the Member that appointed such Director, and the other Member shall be entitled to
rely upon such action without further inquiry or investigation as to the actual authority (or lack
thereof) of such Director.

     Section 4.6 Notice of Company Board Meetings. Written notice of all meetings of the Company Board must be given to all Directors at least
five business days prior thereto. Any such notice, or waiver thereof, need not state the
purpose of such meeting except as may otherwise be required by applicable Law. Attendance of a
Director at a meeting (including pursuant to Section 4.5(b)) shall constitute a waiver of
notice of such meeting, except where such Director attends the meeting for the sole purpose of
objecting to the transaction of any business on the ground that the meeting is not lawfully called
or convened.

     Section 4.7 Action by Written Consent of Directors. To the extent permitted by applicable Law, the Company Board may act without a meeting,
without prior notice and without a vote so long as consents in writing, setting forth the action so
taken, are signed by both Directors. Each written consent shall bear the date and signature of
each Director who signs the consent.

17

 

     Section 4.8 Unanimous Consent Decisions. The Company shall not, and the Operator shall not cause the Company to, take any of the

     (c) initiate, settle, compromise or resolve any Damages or Actions (other than any state or

     (d) except as set forth in an approved Annual Budget, any Approved Project Plan or any
Mandated Project Plan, and except for any expenses or costs as may be required to be incurred in

the disagreement occurred, then either Member may give written notice to the other Member that the
Company Board’s failure to approve such action will, in such Member’s judgment, adversely affect
the Company (a “Dispute Notice”). Within five (5) business days after the delivery of the Dispute
Notice, either Member may submit such Business Dispute to arbitration pursuant to Section
4.10.

19

 

     Section 4.10 Arbitration.

     (a) If either Member desires to submit to arbitration (i) a Business Dispute that remains
unresolved after compliance by the Members with the procedures set forth in Section 4.9,
(ii) a disputed removal of the Operator that remains unresolved after compliance by the Members
with the procedures set forth in Section 4.1(d) or (iii) a purchase price dispute that
remains unresolved after compliance by the Members with the procedures set forth in Section
8.3 (each, an “Arbitrable Dispute”), it shall so notify the other Member in writing, and the
Members shall attempt in good faith to agree on a qualified arbitrator with at least fifteen (15)
years’ experience in the Business within fifteen (15) days after the date of such notice. If the
Members are unable to agree upon a qualified arbitrator within such fifteen (15) day period, then
either Member may request that the CPR Institute appoint an arbitrator with not less than fifteen
(15) years’ experience in the Business. Any arbitrator agreed upon or appointed pursuant to this
Section 4.10(a) is referred to herein as the “Arbitrator.”

     (b) The Arbitrator shall resolve any Arbitrable Dispute submitted to it in accordance with the
provisions of this Agreement.

     (c) The arbitration pursuant to this Section 4.10 shall be conducted in Dallas, Texas,
in accordance with the then current CPR Institute Rules for Non-Administered Arbitration of
Business Disputes, as modified by the provisions of this Section 4.10. The arbitration
shall be governed by the United States Arbitration Act, 9 U.S.C. §§ 116 (the “Federal Arbitration
Act”) to the exclusion of any provision of Law inconsistent therewith or which would produce a
different result, and judgment upon the decision rendered by the Arbitrators may be entered by any
court having jurisdiction. With respect to each Arbitrable Dispute submitted to it, the Arbitrator
shall render its decision in writing within fifteen (15) days after the conclusion of the hearing
with respect to such Arbitrable Dispute (which shall be fixed by the Arbitrator at a reasonable
time and place). The Arbitrator shall have jurisdiction and authority to interpret and apply the
provisions of this Agreement only insofar as shall be necessary in the determination of the
Arbitrable Dispute before it, but shall not have jurisdiction or authority to add to or alter in
any way the provisions of this Agreement. The Arbitrator shall act as a limited expert for the
specific purpose of determining the Arbitrable Dispute in accordance with the terms and
provisions of this Section 4.10, and the Arbitrator may not award Damages, interest or
penalties to either Member with respect to any Arbitrable Dispute. The Arbitrator’s decision shall
govern and shall be final, nonappealable (except to the extent provided in the Federal Arbitration
Act) and binding on the Members and its written decision may be entered in any court having
appropriate jurisdiction. The responsibility for paying the costs and expenses of the arbitration,
including compensation to the Arbitrator, shall be allocated equally among the Members and each
Member shall be responsible for the fees and expenses of its respective counsel, consultants and
witnesses. Any decision of the Arbitrator will be implemented by the Members pursuant to this
Agreement.

     Section 4.11 Officers. The Company Board may, by Unanimous Consent, appoint officers of the Company, having the
titles, power, authority and duties described in this Section 4.11 or as otherwise granted
by the Company Board by Unanimous Consent or this Agreement.

20

 

     (a) Term; Removal; Resignation; Vacancies; Compensation
.. Each officer will hold office until such officer’s resignation, removal or death. Any
officer of the Company is subject to removal, with or without cause, by the Company Board with
Unanimous Consent. Any vacancy in the position of an officer of the Company resulting from a
removal, resignation or other event may be filled by Company Board by Unanimous Consent. The
removal of an officer is without prejudice to the contract rights, if any, of the person removed.
Designation of an officer does not, in and of itself, create contract rights. The compensation, if
any, to be paid to the officers of the Company will be determined by Company Board as provided in
the Annual Budget.

out-of-pocket expenses and costs reasonably incurred in the course of their service hereunder.

     (b) The Operator shall not receive any compensation for managing the affairs of the Company,

in accordance with this Agreement.

     (c) The Operator shall be entitled to charge the Company a monthly fee as reimbursement for
the general and administrative costs incurred by it (such fee, the “G&A Services Fee”). The Members
acknowledge and agree that the G&A Services Fee shall be an amount sufficient to cover the costs
incurred by Operator attributable to office rent and utilities, communications expenses,
information technology and communications support, general accounting services, general legal
services (excluding, however, the costs of outside counsel and other third-party costs for
defending and settling Damages or Actions), engineering services, product control and scheduling,

supplies costs, and other similar items of business.

     Section 5.2 Annual Budgets. From and after the Effective Date, the activities and operations of the Company for each
calendar year shall be set forth in the applicable approved Annual Budget. Each Annual Budget shall
be prepared and approved or disapproved by the Company Board, in accordance with Section
4.8(a), in the following manner:

     (a) Within thirty (30) days after the Effective Date, and thereafter, on or before December

Date), the Operator shall prepare and submit for the approval of the Company Board a budget for the
Company’s activities for the following calendar year (or, with respect to the budget prepared and

will remain after the Effective Date) (the “Annual Budget”), which Annual Budget shall (i) set
forth the estimated (A) capital costs and expenses of the Company (including with respect to any
Approved Project and Mandated Project), (B) fixed operating costs and expenses of the Company
(including with respect to the any Approved Project and Mandated Project) and (C) other line items

23

 

     (b) The Directors shall use reasonable efforts to resolve any disagreements and approve or
disapprove an Annual Budget within twenty (20) days after the date on which the proposed Annual
Budget was submitted to the Company Board for approval. If the Company Board is unable to resolve
any disagreement regarding the Annual Budget during such twenty (20) day period, then (i) the
Directors shall attempt to resolve such disagreement pursuant to Section 4.9 and (ii) until
the Directors resolve any such dispute, the Company Board shall be deemed to have approved an
Annual Budget that incorporates (A) the expenditures and items set forth in the proposed Annual
Budget that are approved by the Company Board by Unanimous Consent and (B) with respect to any
expenditures and items set forth in the proposed Annual Budget that are not approved by the Company
Board by Unanimous Consent, expenditures and items equal to the amounts for any such expenditures
and items that were included in the immediately preceding calendar year’s approved Annual Budget,
as increased by the CPI-U Adjustment Amount, or, if any such expenditures and items were not
included in the immediately preceding calendar year’s Annual Budget (or there was no such Annual
Budget), an amount for such expenditures and items determined by the Operator in good faith. Upon
the resolution of any disputed items, the Annual Budget, as amended to include the applicable
disputed item as resolved, shall be considered approved by the Company Board.

     (c) If, during the period covered by an approved Annual Budget, the Operator determines that
an adjustment to the estimated costs set forth in such Annual Budget is necessary or appropriate,
then the Operator shall submit to the Company Board for approval (if required pursuant to
Section 4.8(a)) such additional line items as are necessary or required. The Company Board
shall review the adjusted Annual Budget within fifteen (15) days after its receipt thereof, and, if
the Company Board does not approve all or any portion of the adjusted Annual Budget
within thirty (30) days after its receipt thereof, then such adjusted Annual Budget (or
portion thereof) shall be deemed to be disapproved by the Company Board.

ARTICLE VI

FISCAL YEAR; BOOKS OF ACCOUNT; CAPITAL ACCOUNTS;

AUDIT RIGHTS; FINANCIAL REPORTS

     Section 6.1 Fiscal Year. The fiscal year of the Company shall be the calendar year.

     Section 6.2 Books of Account. The Operator shall keep the books of account of the Company at the Principal Office, or at
such other place or places as may be approved by the Company Board by Unanimous Consent. The books
of account shall be maintained on an accrual basis in accordance with generally accepted accounting
principles, consistently applied, and shall show all items of investment, income and expense.

     Section 6.3 Capital Accounts. The Company shall establish and maintain a separate Capital Account for each Member in
accordance with the rules of Treasury Regulation section 1.704-1(b)(2)(iv) and in accordance with
the following provisions:

     (a) Each Member’s Capital Account shall be increased by (i) the amount of all Capital
Contributions made to the Company by such Member pursuant to this Agreement, (ii) all items of
Company income and gain computed in accordance with Section 6.3(b) and allocated with
respect to such Member pursuant to Section 9.1, and (iii) the amount of any Company

24

 

liabilities assumed by such Member or that are secured by any Company property distributed to such
Member, and decreased by (w) the amount of cash or Net Agreed Value of property actually or deemed
distributed to such Member pursuant to this Agreement, (x) all items of Company deduction and loss
computed in accordance with Section 6.3(b) and allocated to such Member pursuant to
Section 9.1 and (y) the amount of any liabilities of such Member assumed by the Company or
that are secured by any property contributed by such Member to the Company.

     (b) For purposes of computing the amount of any item of income, gain, loss or deduction,
which is to be allocated pursuant to Article IX and reflected in the Members’ Capital
Accounts, the determination, recognition and classification of any such item shall be the same as
its determination, recognition and classification for federal income tax purposes, provided that:

          (i) All fees and other expenses incurred by the Company to promote the sale of (or to sell) a
Membership Interest that can neither be deducted nor amortized under section 709 of the Code, if
any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the
time such fees and other expenses are incurred and shall be allocated among the Members pursuant to
Section 9.1.

          (ii) Except as otherwise provided in Treasury Regulation section 1.704-1(b)(2)(iv)(m), the
computation of all items of income, gain, loss and deduction shall be made without regard to any
election under section 754 of the Code which may be made by the Company and, as to those items
described in section 705(a)(1)(A) or 705(a)(2)(B) of the Code, without regard to the fact that such
items are not includable in gross income or are neither currently deductible nor capitalized for
federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Company
asset pursuant to section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation
section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount
of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

          (iii) Any income, gain or loss attributable to the taxable disposition of any Company property
shall be determined as if the adjusted basis of such property as of such date of disposition were
equal in amount to the Company’s Carrying Value with respect to such property as of such date.

          (iv) In lieu of the depreciation, amortization and other cost recovery deductions taken into
account in computing such items, there shall be taken into account Depreciation, computed in
accordance with the definition of Depreciation.

          (v) For purposes of determining income, gain, loss, and deduction, or any other item allocable
to any period, such items will be determined on a daily, monthly or other basis, as reasonably
determined by the Company Board by Unanimous Consent using any permissible method under Code
section 706 and the related Treasury Regulations.

     (c) A Transferee shall succeed to the pro rata portion of the Capital Account of the
transferor relating to the Membership Interest so transferred. Except as otherwise provided herein,
all items of income, gain, expense, loss, deduction and credit allocable to any

25

 

Membership Interest
that may have been transferred during any calendar year shall, if permitted by Law, be allocated
between the transferor and the transferee based on the portion of the calendar year during which
each was recognized as owning that Membership Interest, based upon the interim closing of the books
method; provided, however, that this allocation must be made in accordance with a method
permissible under section 706 of the Code and the Treasury Regulations thereunder.

     (d) (i) In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), on any issuance
of additional Membership Interests for cash or Contributed Property and any issuance of Membership
Interests as consideration for the provision of services, the Capital Accounts of both Members and
the Carrying Value of each Company property immediately prior to such issuance or adjustment shall
be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to
such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized on an
actual sale of each such property immediately prior to such issuance or adjustment and had been
allocated to the Members at such time pursuant to Section 9.1 in the same manner as any
item of gain or loss actually recognized during such period would have been allocated. In
determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and Fair Market
Value of all Company assets (including cash and cash equivalents) immediately prior to the issuance
of additional Membership Interests shall be
determined by the Company Board using such method of valuation as it may adopt by Unanimous
Consent. The Company Board shall by Unanimous Consent allocate such aggregate value among the
assets of the Company (in such manner as it determines) to arrive at a Fair Market Value for
individual properties.

          (ii) In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), immediately prior to
any actual or deemed distribution to a Member of any Company property (other than a distribution of
cash that is not in redemption or retirement of a Membership Interest), the Capital Accounts of
both Members and the Carrying Value of all Company property shall be adjusted upward or downward to
reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such
Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior
to such distribution for an amount equal to its Fair Market Value, and had been allocated to the
Members, at such time, pursuant to Section 9.1 in the same manner as any item of gain or
loss actually recognized during such period would have been allocated. In determining such
Unrealized Gain or Unrealized Loss, the aggregate cash amount and Fair Market Value of all Company
assets (including cash and cash equivalents) immediately prior to a distribution shall (A) in the
case of an actual distribution that is not made pursuant to Section 11.3 or in the case of
a deemed distribution, be determined and allocated in the same manner as that provided in
Section 6.3(d)(i) or (B) in the case of a liquidating distribution pursuant to Section
11.3, be determined and allocated by the Liquidator using such method of valuation as it may
adopt.

     Section 6.4 Member Audit Rights.

     (a) The Non-Operating Member shall have the right at any time during, and up to twenty-four
(24) months after the close of, any fiscal year, but not more than twice in any twelve (12) month
period, to audit, examine and make copies of or extracts from the books of account or any other
records of or relating to the Company pertaining to that fiscal year. This right may be

26

 

exercised
during normal business hours through any agent or employee of the Non-Operating Member or by an
independent certified public accountant designated by the Non-Operating Member. The Non-Operating
Member requesting an audit shall give at least thirty (30) days’ advance written notice of its
desire to conduct an audit. During such thirty (30) day period, the Members shall determine a
mutually agreeable time for the audit to occur, but the Operator must agree to an acceptable time
within sixty (60) days after the originally requested time. The Non-Operating Member shall be
solely responsible for all costs and expenses incurred in any examination or audit.

     (b) All books of account or other records of the Company shall be conclusively presumed to be
true and correct after twenty-four (24) months following the end of any fiscal year unless a Member
makes a written claim for adjustment within such twenty-four (24) month period. Failure to make a
claim for adjustment within that period shall conclusively establish the correctness of such books
and/or records, and shall preclude the making of claims for adjustment thereon in any manner
whatsoever, whether by filing an Action in a court of law, or otherwise. Notwithstanding the above,
the Operator can make adjustments to any books of account or other records of the Company with the
Company Board’s Unanimous Consent.

     Section 6.5 Reports.

     (a) The Operator shall provide (or cause to be provided) the following unaudited periodic
financial information to the Members:

          (i) a monthly income statement and balance sheet provided no later than twenty-five (25) days
following the end of each month;

          (ii) a quarterly income statement, balance sheet and statement of cash flows within
twenty-five (25) days after the end of each fiscal quarter (with the exception of the last fiscal

          (iii) an annual income statement, balance sheet, statement of cash flows and statement of
changes in Members’ capital within thirty-five (35) days after the end of each fiscal year.

Annual Budget approved by the Company Board and, with the exception of the first fiscal year, be
presented on a comparable basis with the income statement and statement of cash flows presented for
both the current period(s) (including fiscal year-to-date amounts) and the corresponding period(s)
of the preceding fiscal year and the balance sheet presented as of the end of the current period
and as of the end of the preceding fiscal year.

     (c) The financial statements set forth in Section 6.5(a) shall be prepared in

applied (except as therein noted) and shall fairly present the financial position, results of
operations, and changes in Members’ capital. In addition to the financial statements and reports
set forth in Section 6.5(a), the Operator may cause to be prepared or delivered such other
reports as it may deem appropriate. The Company shall bear the costs of all the financial
statements and reports described in this Section 6.5.

27

 

     (d) Within fifteen (15) days after the request of a Member, to the extent reasonably
available, the Operator shall deliver to such Member such accounting, tax information and schedules
as shall be necessary for the tax reporting purposes of such Member with respect to the relevant
calendar year.

     (e) In addition to the obligations under the foregoing provisions of this Section 6.5,
the Operator shall timely prepare and deliver (or cause to be timely prepared and delivered) to any
Member, upon its request, all financial statements, notes thereto and additional financial
information as may be required in order for such Member or an Affiliate of such Member to comply
with any reporting requirements under (i) the Securities Act (and the rules and regulations
promulgated thereunder), (ii) the Exchange Act and the rules and regulations promulgated thereunder
and (iii) any national securities exchange or automated quotation system.

     (f) The Operator shall also cause to be prepared and delivered to each Member such other
reports, forecasts, studies, budgets and other information as the Directors may request from time
to time.

     (g) With reasonable promptness, the Operator shall deliver to each Member such other
information and financial data concerning the Company as such Member may reasonably request.

     Section 6.6 Accounts. The Operator shall establish and maintain one or more separate bank and investment accounts
and arrangements for Company funds in the Company’s name with such financial institutions and firms
that it determines.

ARTICLE VII

     (a) Neither Member shall be required to make any additional Capital Contribution other than a
Required Contribution.

     (b) Each Member agrees to contribute to the Company (within five days after any capital call
issued by the Operator with respect thereto) (i) such Member’s Percentage Interest share of the Net
Adjustment Amount (as defined in the Purchase Agreement), if positive, (ii) such Member’s
Percentage Interest share of any Capital Contributions approved by the Company Board by Unanimous
Consent, and (iii) such Member’s Percentage Interest share of any Capital Contribution to fund any
Approved Project (as set forth in the Approved Project Plan) or Mandated Project (as set forth in
the Proposed Expansion Project Presentation), in each case only to the extent that such Approved
Project or Mandated Project is not funded with third party debt financing (each, a “Required
Contribution”).

     (c) It is acknowledged and agreed that (i) on the date hereof, in connection with the closing
of the transactions contemplated by the Purchase Agreement, ETP paid, in accordance with the terms
of the Purchase Agreement, $1,380,588,908.55 on behalf of the Company, and in partial satisfaction
of the Company’s payment obligations set forth in the Purchase Agreement,

28

 

(ii) ETP shall be deemed
to have contributed $1,380,588,908.55 to La Grange, and La Grange shall be deemed to have
contributed $1,380,588,908.55 to the Company.

     (d) It is acknowledged and agreed that (i) on the date hereof, in connection with the closing
of the transactions contemplated by the Purchase Agreement, Regency paid, in accordance with the
terms of the Purchase Agreement, $591,680,960.81 on behalf of the Company, and in partial

shall be deemed to have contributed $591,680,960.81 to REM, and REM shall be deemed to have
contributed $591,680,960.81 to the Company.

     Section 7.2 Failure to Contribute.

     (a) If a Member is in Default as a result of its failure to contribute all or any portion of a
Required Contribution that such Member (a “Delinquent Member”) is required to make as provided in
this Agreement, then, while such Member is a Delinquent Member, the non-Delinquent Member may (but
shall have no obligation to) elect to advance the entire amount of the Delinquent Member’s Required
Contribution that is in Default, in which case the Membership Interests and Percentage Interest of
each Member shall be adjusted to equal the amount (expressed as a percentage) determined by
dividing the total Capital Contributions made by such Member by the total Capital Contributions
made by both Members; provided, however, that the Delinquent Member may cure such delinquency by
contributing its Percentage Interest share (prior to any adjustment pursuant to this Section
7.2(a)) of such Required Contribution, plus interest at the Default Interest Rate, within
fifteen (15) days after the date on which such Required Contribution was initially due, and such
Delinquent Member’s Membership Interest and Percentage Interest shall be restored as if an
adjustment pursuant to this Section 7.2(a) had never been made.

     (b) If either Member fails to make any Required Contribution, then, in addition to the rights
granted elsewhere in this Section 7.2, the Company and the non-Delinquent Member shall each
have the right to exercise the following remedies with respect to the Delinquent Member:

          (i) the Company or the non-Delinquent Member may at any time take such action (including
instigating court Actions) as the Company or the non-Delinquent Member may deem appropriate to

Contribution that is in Default, along with all costs and expenses associated with the collection
thereof; and

          (ii) the Company or the non-Delinquent Member may at any time exercise any other rights and
remedies available under this Agreement or at law or in equity.

ARTICLE VIII

RESTRICTIONS ON TRANSFERS; BANKRUPTCY EVENTS;

CHANGES OF CONTROL

     Section 8.1 Generally.

     (a) No Member may Transfer (or grant a Lien on) any portion of its Membership Interest unless
it has received the prior written consent of the other Member (which such consent

29

 

may not be
unreasonably withheld or delayed) and such Transfer (or grant of a lien on) is made in accordance
with applicable Law and the terms of this Agreement.

     (b) Any purported Transfer of (or grant of a Lien on) any portion of a Member’s Membership
Interest in breach of the terms of this Agreement shall be null and void ab initio, and the Company
shall not recognize any such prohibited Transfer (or grant of a Lien).

     (c) The Members acknowledge and agree that a breach of any of the terms of this Article
VIII by a Member will likely cause irreparable injury to the Company and to the other Member
for which monetary damages and 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 such Member to comply with the provisions of this Article VIII and (ii) the uniqueness
of the Business and the relationship among the Members. Accordingly, the Members acknowledge and
agree that the provisions of this Article VIII may be enforced by specific performance.

     Section 8.2 Permitted Transfers. Notwithstanding the provisions of this Article VIII, each Member shall have the
right, without the consent of the other Member, to (a) Transfer all (but not less than all) of its
Membership Interests to a Subsidiary of such Member’s Ultimate Parent (and upon any such Transfer,
such Subsidiary shall immediately become a Member), (b) make a bona fide pledge of its Membership
Interests under a credit facility with third party financial institutions or (c) Transfer all or
any portion of its Membership Interest in compliance with Sections 8.4, 8.5 and/or
8.6.

     Section 8.3 Bankruptcy Event; Change of Control. If (i) a Bankruptcy Event occurs with respect to a Member or (ii) a Member undergoes a
Change of Control, such Member (the “Triggering Member”) shall provide written notice of such
Bankruptcy Event or Change of Control to the other Member (the “Option Member”) within one (1) day
of such occurrence, and the Option Member shall have the right, but not the obligation, to purchase
all of the Triggering Member’s Membership Interest, such right to be exercised within thirty (30)
days after the Option Member’s receipt of such written notice. The purchase price to be paid by
the Option Member shall be the fair market value of the Triggering Member’s Membership Interest as
determined by agreement between the Members. If the Members are unable to agree upon a purchase
price, such purchase price will be determined by arbitration in accordance with Section
4.10.

     Section 8.4 Right of First Refusal.

     (a) If a Member (such Member, a “Selling Member”) receives a bona fide offer from a third
party for a Transfer of all or a portion of the Selling Member’s Membership Interest (the “Subject
Interest”), and the Selling Member wishes to accept such offer, the Selling Member must notify the
other Member (the “Non-Selling Member”) in writing within twenty (20) days after receiving such
offer (the “Sale Notice”). The Sale Notice must include a complete description of the purchase
price and other terms and conditions of the transaction in which the Selling Member proposes to
Transfer the Subject Interest, including the name of the proposed Transferee and other
consideration specified in the offer. The Non-Selling Member shall have twenty (20) days (the
“ROFR Option Period”) after receiving the Sale Notice in which to advise

30

 

the Selling Member in
writing (the “ROFR Acceptance Notice”) whether or not it will acquire all of the Subject Interest
upon the terms and conditions contained in the Sale Notice. A failure to
advise the Selling Member in writing as to whether or not it will acquire all of the Subject
Interest pursuant to the preceding sentence shall be deemed to constitute an election not to
acquire the Subject Interest.

     (b) If, during the ROFR Option Period, the Non-Selling Member elects to acquire the Subject
Interest at the price and subject to the terms and conditions set forth in the Sale Notice (upon
such election, the “ROFR Accepting Member”), then such ROFR Accepting Member shall close such
transaction no later than the later to occur of (i) the closing date set forth in the Sale Notice
and (ii) 90 days after the Selling Member receives the ROFR Acceptance Notice.

     (c) The right of first refusal created in this Section 8.4 is an option to acquire
all, but not less than all, of the Subject Interest offered for sale by the Selling Member. If the
Non-Selling Member elects not to acquire the Subject Interest or the Non-Selling Member fails to
make an election before the expiration of the ROFR Option Period, and the Selling Member has
complied with Section 8.5, the Selling Member may Transfer the Subject Interest to the
proposed Transferee named in the Sale Notice upon the terms described in the Sale Notice. If such
Transfer does not occur on substantially the same terms and conditions set forth in the Sale
Notice, or if such Transfer is not consummated within one hundred twenty (120) days after the
Non-Selling Member’s election not to acquire the Subject Interest, then such Transfer shall be null
and void ab initio and the Selling Member must again satisfy all of the requirements of this
Section 8.4.

     (d) Upon consummation of any Transfer of Membership Interests in accordance with this
Section 8.4 (whether to a Member or any other Person), such Transferee and all of its
Membership Interest shall automatically be admitted as a Member, become a party to and be bound by
this Agreement and shall thereafter have all of the rights and obligations of a Member hereunder.
Notwithstanding the foregoing, all Transfers pursuant to this Section 8.4 must comply with
the terms of this Agreement.

     (e) In connection with the Non-Selling Member’s decision regarding whether to exercise the
option to purchase the Subject Interest as described herein, the Non-Selling Member may elect to
engage a Valuation Firm to determine the current Fair Market Value of the Subject Interest. If the
Non-Selling Member and the Selling Member are unable to agree on the selection of a Valuation Firm
within ten (10) days after delivery of the Sale Notice, then (i) the Non-Selling Member and the
Selling Member shall each select a Valuation Firm to advise them in connection with such valuation
within fifteen (15) days after the delivery of the Sale Notice, and (ii) the Valuation Firms
selected by the Non-Selling Member and the Selling Member shall agree on and select a third
Valuation Firm within twenty (20) days after the delivery of the Sale Notice, which Valuation Firm
shall be the “Valuation Firm” for the purposes of this Section 8.4(e). The Valuation Firm
that is selected in accordance with procedures set forth in this Section 8.4(e) shall then,
within ten (10) days after its selection, determine in good faith the then current Fair Market
Value in cash of the Subject Interest and prepare and deliver to each Member a report stating such
Fair Market Value and including a summary of the assumptions and basis for such determination. The
cost of such report shall be borne by the Company. Notwithstanding anything in this Section
8.4 to the contrary, if a Valuation Firm is engaged pursuant to this

31

 

Section 8.4(e),
the ROFR Option Period shall be extended by a number of days equal to the total
number of days in the period starting from the delivery of the Sale Notice and ending on the
date on which the Members receive the Valuation Firm report.

     Section 8.5 Tag-Along Right.

     (a) If (w) a Selling Member has complied with Section 8.4, (x) the Non-Selling Member
has elected not to acquire the Subject Interest or has failed to make an election before the
expiration of the ROFR Offer Period, (y) such Selling Member is proceeding with the Transfer of the
Subject Interest pursuant to Section 8.4(c) and (z) the Subject Interest which the Selling
Member proposes to Transfer represents more than twenty percent (20%) of the Selling Member’s
Membership Interest, then such Selling Member shall make an offer (a “Tag-Along Offer”) to the
Non-Selling Member to include in the proposed Transfer (the “Tag-Along Transfer”), on substantially
the same terms and conditions set forth in the Sale Notice, all or a portion (as the case may be)
of the Non-Selling Member’s Membership Interest in accordance with the provisions of this Section
8.5.

     (b) Each of the Selling Member and the Non-Selling Member shall have the right to Transfer in
a Tag-Along Transfer a Percentage Interest equal to the product of (i) the total Percentage
Interest of the Selling Member or Non-Selling Member (as the case may be) (expressed as a decimal)
multiplied by (ii) the Subject Interest the proposed Transferee proposes to buy as stated in the
Sale Notice (expressed as a percentage).

     (c) The Tag-Along Offer may be accepted by the Non-Selling Member at any time within twenty
(20) days after the Non-Selling Member’s receipt of the Tag-Along Offer, which acceptance must be
made by delivery of a written notice indicating such acceptance to the Selling Member (a “Tag-Along
Acceptance Notice”).

     (d) The Selling Member may elect in its discretion to terminate the proposed sale of any of
its Membership Interest in the Tag-Along Transfer (and shall not otherwise be deemed to owe any
duty or responsibility to the Non-Selling Member to proceed), in which case, the obligations under
this Section 8.5 in respect of such Tag-Along Transfer shall cease.

     (e) If for any reason the Selling Member elects to terminate or otherwise not to sell any of
its Membership Interest in the Tag-Along Transfer or such Tag-Along Transfer should fail to close,
the Selling Member must comply with the provisions set forth in Sections 8.4 and
8.5, to the extent applicable, prior to making any subsequent Transfer of all or any
portion of its Membership Interest.

     Section 8.6 Drag-Along Right.

     (a) If (w) a Selling Member has complied with Sections 8.4 and 8.5, (x) the
Non-Selling Member has (i) elected not to acquire the Subject Interest or has failed to make an
election before the expiration of the ROFR Offer Period and (ii) failed to accept the Tag-Along
Offer, (y) such Selling Member is proceeding with the Transfer of the Subject Interest pursuant
to Section 8.4(c) and (z) the Subject Interest which the Selling Member proposes to
Transfer represents more than fifty percent (50%) of the Selling Member’s Membership Interest, then
the Selling Member may require the Non-Selling Member to sell in such Transfer (a “Drag-Along

32

 

Transfer”), on substantially the same terms and conditions set forth in the Sale Notice, the same
proportion of its Membership Interest as is proposed to be sold by the Selling Member.

     (b) The Selling Member shall give the Non-Selling Member written notice at least twenty five
(25) days prior to the anticipated closing date of the Drag-Along Transfer (a “Drag-Along Notice”).
Upon delivery of the Drag-Along Notice, the Non-Selling Member shall be required to sell to the
Transferee the same proportion of its Membership Interest as the Selling Member actually sells
pursuant to the Drag-Along Transfer.

     (c) The Selling Member may elect in its discretion to terminate or otherwise not to sell any
of its Membership Interest in the Drag-Along Transfer (and shall not otherwise be deemed to owe any
duty or responsibility to the Non-Selling Member to proceed), in which case, the obligations under
this Section 8.6 in respect of such Drag-Along Transfer shall cease.

     (d) If for any reason the Selling Member elects to terminate or otherwise not to sell any of
its Membership Interest in the Drag-Along Transfer or such Drag-Along Transfer should fail to
close, the Selling Member must comply with the provisions set forth in Sections 8.4 and
8.5, to the extent applicable, prior to making any subsequent Transfer of all or any
portion of its Membership Interest.

     Section 8.7 Asset Right of First Refusal.

     (a) If the Company receives (i) a bona fide written offer from a third party for a purchase of
all or a portion of the Company’s assets or properties (the “Subject Assets”) which includes a
complete description of the purchase price and other terms and conditions of the transaction in
which the Subject Assets would be sold, including the name of the third party purchaser and the
other consideration specified in such offer (a “Subject Assets Bona Fide Offer”), (ii) the Company
Board, by Unanimous Consent, determines that the Company would be willing to sell such Subject
Assets at the price and on the other terms set forth in such Subject Assets Bona Fide Offer and
(iii) either Member wishes to purchase such Subject Assets at the price and on the other terms set
forth in such Subject Assets Bona Fide Offer, such Member (the “Potential Purchasing Member”) must
notify the other Member in writing within ten (10) days after the Company’s receipt of such Subject
Assets Bona Fide Offer (the “Asset Purchase Notice”). The Potential Purchasing Member shall have
ten (10) days (the “Asset ROFR Option Period”) after delivering the Asset Purchase Notice in which
to advise the other Member in writing (the “Asset ROFR Exercise Notice”) whether or not it will
acquire all of the Subject Assets on the same terms and conditions set forth in the Subject Assets
Bona Fide Offer. A failure to advise the Selling Member in writing as to whether or not it will
acquire all of the Subject Assets pursuant to the preceding sentence shall be deemed to constitute
an election not to acquire the Subject Assets.

     (b) If, during the Asset ROFR Option Period, the Potential Purchasing Member delivers the
Asset ROFR Exercise Notice, then the Potential Purchasing Member shall close such transaction no
later than the later to occur of (i) the closing date set forth in the Subject Assets Bona Fide
Offer and (ii) 90 days after the delivery of the Asset ROFR Exercise Notice.

33

 

     (c) The right of first refusal created in this Section 8.7 is an option to acquire
all, but not less than all, of the Subject Assets offered to be purchased by the third party. If
the Potential Purchasing Member elects not to acquire the Subject Assets or the Potential
Purchasing Member fails to make an election before the expiration of the Asset ROFR Option Period,
and the sale of the assets has received approval of the Company Board by Unanimous Consent pursuant
to Section 4.8(f) (if required), the Company may sell the Subject Assets to the proposed
purchaser named in the Subject Assets Bona Fide Offer upon the terms described therein. If such
sale does not occur on substantially the same terms and conditions set forth in the Subject Assets
Bona Fide Offer, or if such sale is not consummated within one hundred twenty (120) days after the
Potential Purchasing Member’s election not to acquire the Subject Assets, then such sale shall be
null and void ab initio and the Company must again satisfy all of the requirements of this
Section 8.7.

     Section 8.8 Additional Restrictions.

     (a) No Member may effect or be the subject of a Transfer, Change of Control or any other
indirect transfer of its Membership Interest that would result in a termination of the Company
pursuant to section 708(b)(1)(B) of the Code (each, a “Tax Termination Event”) unless such Member
meets the requirements of this Section 8.8(a). Prior to any Tax Termination Event, the
Transferring Member or its Ultimate Parent must offer to pay to the non-Transferring Member in cash
the amount (the “Make-Whole Amount”) necessary to hold such non-Transferring Member harmless against any deferral of state or federal income tax depreciation
or other increase in liability for such tax (including any change in the present value of such
liability) that such Tax Termination Event would cause; provided, however, that if both Members, in
any twelve (12) month period, effect or are the subject of a Tax Termination Event that requires
the payment of the Make-Whole Amount to the other Member under this Section 8.8(a), then
the liability for the Make-Whole Amount will be apportioned between the Members, and each Member
will be individually liable for its allocated portion of the Make-Whole Amount, which shall be
determined by (i) dividing the Membership Interest directly or indirectly Transferred by such
Member by the total Membership Interests directly or indirectly Transferred by both Members in the
applicable twelve (12) month period and (ii) multiplying the ratio calculated in (i) by the total
Make-Whole Amount calculated in accordance with, and required to be paid to the other Member under,
the provisions of this Section 8.8(a). For purposes of calculating the Make-Whole Amount,
each non-Transferring Member will be treated as if it is a corporation for federal and state income
tax purposes. In the case of any Tax Termination Event to which this Section 8.8(a)
applies, the Make-Whole Amount for each Member entitled to be paid that amount will be computed on
a net present value basis using: (i) the Agreed Rate in effect on the date of payment and (ii) the
highest marginal applicable state and federal corporate income tax rates for the year of payment.
Using those same highest marginal rates, the amount that is determined pursuant to the preceding
sentence will be grossed up such that the increased amount reduced by the state and federal income
tax that is deemed paid by reason of the receipt thereof is equal to the amount that is determined
pursuant to the preceding sentence. If the applicable state income tax is deductible for federal
income tax purposes, effect will be given to that deduction in calculating the Make-Whole Amounts.
Each Member may accept this payment, or, at its sole option, receive full indemnity on such
after-tax basis from the applicable Member’s Ultimate Parent for all state and federal income tax
impacts relating to that Member directly resulting from the Tax Termination Event.

34

 

     (b) Notwithstanding anything to the contrary set forth in this Article VIII, no Member
may effect a Transfer that, in the Company Board’s reasonable judgment, subjects the Company, the
Pipeline or any of the Company’s other assets and facilities to regulation by FERC under the ICA.

ARTICLE IX

PROFITS AND LOSSES; DISTRIBUTIONS

     Section 9.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts, the Company’s items of income, gain, loss
and deduction (computed in accordance with Section 6.3(b)) shall be allocated among the
Members in each taxable year (or portion thereof) as provided in this Section 9.1.

     (a) Allocations. After giving effect to the special allocations set forth in
Section 9.1(b), for each taxable year of the Company (including the taxable year in which
the dissolution or liquidation of the Company occurs) all remaining items of income, gain, loss and
deduction shall be allocated among the Members in proportion to their respective Percentage
Interest.

     (b) Special Allocations. Notwithstanding any other provision of this Section
9.1, the following special allocations shall be made for such taxable period in the following
order and priority:

          (i) Company Minimum Gain Chargeback. Notwithstanding the other provisions of this
Section 9.1, if there is a net decrease in Company Minimum Gain during any Company taxable
period, each Member shall be allocated items of Company income and gain for such taxable period
(and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury
Regulation sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provisions.
For purposes of this Section 9.1(b), each Member’s Adjusted 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 9.1(b) with respect to
such taxable period (other than an allocation pursuant to Sections 9.1(b)(iv) and
9.1(b)(v)). This Section 9.1(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) Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt.
Notwithstanding the other provisions of this Section 9.1 (other than Section
9.1(b)(i)), except as provided in Treasury Regulation section 1.704-2(i)(4), if there is a net
decrease in Member Nonrecourse Debt Minimum Gain during any Company taxable period, either Member
with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall
be allocated items of Company income and gain for such taxable period (and, if necessary,
subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections
1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section
9.1(b), each Member’s Adjusted 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 9.1(b), other than Section 9.1(b)(i) and other
than an allocation pursuant to Sections 9.1(b)(vi) and 9.1(b)(ix),
with respect to such taxable period.

35

 

This Section 9.1(b)(ii) is intended to comply with the chargeback of
items of income and gain requirement in Treasury Regulation section 1.704-2(i)(4) and shall be
interpreted consistently therewith.

          (iii) Qualified Income Offset. In the event either Member unexpectedly receives any
adjustments, allocations or distributions described in Treasury Regulation sections
1.704-1(b)(2)(ii)(d)(4) through (6), items of Company income and gain shall be specially allocated
to such Member in an amount and manner sufficient to eliminate, to the extent required by the
Treasury Regulations promulgated under section 704(b) of the Code, the deficit balance, if any, in
its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly
as possible; provided that, an allocation pursuant to this Section 9.1(b)(iii) shall be
made only if and to the extent that such Member would have a deficit in such Member’s Adjusted
Capital Account after all other allocations provided in this Article IX have been
tentatively made as if this Section 9.1(b)(iii) were not a part of this Agreement. This
Section 9.1(b)(iii) is intended to be a “qualified income offset” as that term is used in
Treasury Regulation section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

          (iv) Gross Income Allocations. In the event either Member has a deficit balance in its
Adjusted Capital Account at the end of any Company taxable period in excess of the sum of (A) the
amount such Member is obligated to restore pursuant to any provision of this Agreement and (B) the
amount such Member is deemed obligated to restore pursuant to Treasury Regulations sections
1.704-2(g) and 1.704-2(i)(5), such Member shall be specially allocated items of Company gross
income and gain in the amount of such excess as quickly as possible; provided that, an allocation
pursuant to this Section 9.1(b)(iv) shall be made only if and to the extent that such
Member would have a deficit balance in its Adjusted Capital Account after all other allocations
provided in this Article IX have been tentatively made as if this Section
9.1(b)(iv) were not a part of this Agreement.

          (v) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be
allocated to the Members in accordance with their respective Percentage Interests. If the Company
Board determines by Unanimous Consent that the Company’s Nonrecourse Deductions should be allocated
in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations
promulgated under section 704(b) of the Code, then the Company Board is authorized, upon notice to
the Members, to revise the prescribed ratio to the numerically closest ratio which does satisfy
such requirements.

          (vi) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable
period shall be allocated one hundred percent (100%) to the Member that bears the Economic Risk of
Loss with respect to such Member Nonrecourse Debt to which such Member Nonrecourse Deductions are
attributable in accordance with Treasury Regulation section 1.704-2(i). If both Members bear the
Economic Risk of Loss with respect to a Member Nonrecourse Debt, such Member Nonrecourse Deductions
attributable thereto shall be allocated between or among the Members in accordance with the ratios
in which they share such Economic Risk of Loss.

36

 

          (vii) Depreciation. Except as otherwise provided for in this Section 9.1(b),
Depreciation deductions shall be allocated among the members in accordance with their Percentage
Interests.

          (viii) Nonrecourse Liabilities. For purposes of Treasury Regulation section
1.752-3(a)(3), the Members agree that Nonrecourse Liabilities of the Company in excess of the sum
of (A) the amount of Company Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain
shall be allocated among the Members in accordance with their respective Percentage Interests.

          (ix) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax
basis of any Company asset pursuant to section 734(b) or 743(b) of the Code is required, pursuant
to Treasury Regulation section 1.704-1(b)(2)(iv)(m), to be taken into account in determining
Capital Accounts, 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 specially allocated to the Members in a manner
consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to
such section of the Treasury Regulations.

     Section 9.2 Allocations for Tax Purposes.

     (a) Except as otherwise provided herein, for federal income tax purposes, each item of income,
gain, loss and deduction shall be allocated among the Members in the same manner as its correlative
item of “book” income, gain, loss or deduction is allocated pursuant to Section 9.1.

     (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or
Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery
deductions shall be allocated for federal income tax purposes among the Members as follows:

          (i) (A) In the case of a Contributed Property, such items attributable thereto shall be
allocated among the Members in the manner provided under section 704(c) of the Code that takes into
account the variation between the Agreed Value of such property and its adjusted basis at the time
of contribution, and (B) any item of Residual Gain or Residual Loss attributable to a Contributed
Property shall be allocated among the Members in the same manner as its correlative item of “book”
gain or loss is allocated pursuant to Section 9.1.

          (ii) (A) In the case of an Adjusted Property, such items shall (1) first, be allocated among
the Members in a manner consistent with the principles of section 704(c) of the Code to take into
account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations
thereof pursuant to Section 6.3(d)(i) or 6.3(d)(ii), and (2) second, in the event
such property was originally a Contributed Property, be allocated among the Members in a manner
consistent with Section 9.2(b)(i)(A); and (B) any item of Residual Gain or Residual Loss
attributable to an Adjusted Property shall be allocated among the Members in the same manner as its
correlative item of “book” gain or loss is allocated pursuant to Section 9.1.

          (iii) The Company Board shall apply the principles of Treasury Regulation section 1.704-3(d)
to eliminate Book-Tax Disparities.

37

 

     (c) For the proper administration of the Company, the Company Board shall, by Unanimous
Consent, (i) adopt such conventions as it deems appropriate in determining the amount of
depreciation, amortization and cost recovery deductions, (ii) make special allocations for federal
income tax purposes of income (including gross income) or deductions, and (iii) amend the
provisions of this Agreement as appropriate to reflect the proposal or promulgation of Treasury
Regulations under section 704(b) or section 704(c) of the Code. The Company Board may adopt such
conventions, make such allocations and make such amendments to this Agreement as provided in this
Section 9.2(c) only if such conventions, allocations or amendments are consistent with the
principles of section 704 of the Code and would not have a material adverse effect on the Members.

     (d) Any gain allocated to the Members upon the sale or other taxable disposition of any
Company asset shall, to the extent possible, after taking into account other Required Allocations
of gain pursuant to this Section 9.2(d), be characterized as Recapture Income in the same
proportions and the same extent as the Members (or their predecessors in interest) have
been allocated any deductions directly or indirectly giving rise to the treatment of such
gains as Recapture Income.

     (e) All items of income, gain, loss, deduction and credit recognized by the Company for
federal income tax purposes and allocated to the Members in accordance with the provisions hereof
shall be determined without regard to the election under section 754 of the Code that will be made
by the Company; provided, however, that such allocations, once made, shall be adjusted (in any
manner determined by the Company Board by Unanimous Consent) as necessary or appropriate to take
into account those adjustments permitted or required by sections 734 and 743 of the Code.

     Section 9.3 Allocations on Transfer. In the event of a Transfer of all of a Member’s Membership Interest (in accordance with the
provisions of this Agreement) at any time other than the end of any fiscal year, the shares of
items of Company income, gain, loss and deduction, and specially allocated items allocable to the
Membership Interest Transferred, shall be allocated between the Transferring Member and the
Transferee in a manner determined by the Company Board by Unanimous Consent that is not
inconsistent with the applicable provisions of the Code and Treasury Regulations.

     Section 9.4 Requirement of Distributions.

     (a) Subject to the immediately succeeding sentence, within forty (40) days following the end
of each fiscal quarter, notwithstanding anything to the contrary set forth in Articles VI
and IX, the Company shall distribute 100% of its Available Cash with respect to such fiscal
quarter to the Members in proportion to their respective Percentage Interests. All distributions
required to be made under this Agreement shall be made subject to Sections 18-607 and 18-804 of the
Act, as applicable.

     (b) Notwithstanding Section 9.4(a), in the event of the dissolution and liquidation of
the Company, all receipts received during or after the month in which the Dissolution Event occurs
shall be applied and distributed solely in accordance with, and subject to the terms and conditions
of, Section 11.3.

ARTICLE X

TAX STATUS, TAX ELECTIONS AND TAX MATTERS MEMBER

     Section 10.1 Tax Status. It is the intention of the Members that the Company be classified as a partnership for U.S.
federal and state income tax purposes. Neither the Company nor either Member shall make an election
for the Company 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.

become a “notice partner” within the meaning of section 6223 of the Code and shall inform each
Member of all significant matters that may come to its attention in its capacity as Tax Matters
Member by giving notice thereof on or before the fifth business day after becoming aware thereof
and, within that time, shall forward to the other Member copies of all significant written
communications it may receive in that capacity. The Tax Matters Member may not take any action
contemplated by sections 6222 through 6231 of the Code without the Unanimous Consent of the Company
Board, but this sentence does not authorize the Tax Matters Member to take any action left to the
determination of an individual Member under sections 6222 through 6231 of the Code. The Tax Matters

Member an opportunity to review and comment upon any such tax returns prior to the filing of such
tax returns.

     (b) Tax Statements and Information.

          (i) On or before the last day of March during the existence of the Company, the Operator shall

          (ii) From time to time, the Operator shall cause each Member to be furnished with any other
financial or tax information regarding the Company reasonably requested by such Member (or its
Affiliates and designees), including, (A) book and tax basis information for the Company’s assets
sufficient to allow such Member to satisfy its own obligations and make its own computations,

service providers (including the Company’s accountants) of the Company.

Member consents to the continuation of the Company.

     Section 11.2 Winding-Up. When the Company is dissolved, the business and property of the Company shall be wound up
and liquidated by such party appointed by the Company Board by Unanimous Consent (the party

its best efforts to reduce to cash and cash equivalent items such assets of the Company as the
Liquidator shall deem it advisable to sell, subject to obtaining fair value of such assets and any
tax or other legal considerations.

40

 

     Section 11.3 Final Distribution. Within 90 calendar days after the effective date of dissolution of the Company, the assets
of the Company shall be distributed in the following manner and order:

Company;

     (b) to pay all creditors of the Company, either by the payment thereof or the making of
reasonable provision therefor;

     (c) to establish reserves, in amounts reasonably established by the Liquidator, to meet other

REGISTRATION RIGHTS

     Section 2.1 Registration.

          (a) Request for Filing and Deadline To Become Effective. Within thirty (30) days of
Closing, the Partnership shall file a Resale Registration Statement to permit the public resale of
Registrable Securities then outstanding from time to time as permitted by Rule 415 of

3

 

the Securities Act. The Partnership shall prepare and file a Resale Registration Statement
under the Securities Act with respect to all of the Registrable Securities of the Holders unless
the Holder has opted out of inclusion pursuant to Section 2.1(b). The Resale Registration
Statement filed pursuant to this Section 2.1(a) shall be on such appropriate registration form of
the Commission as shall be selected by the Partnership. The Partnership shall use its commercially
reasonable efforts to cause the Resale Registration Statement to become effective no later than 60
days following the Closing Date (the “Target Effective Date”). The Partnership will use
its commercially reasonable efforts to cause the Resale Registration Statement filed pursuant to
this Section 2.1 to be continuously effective under the Securities Act until all Registrable
Securities covered by the Resale Registration Statement have ceased to be Registrable Securities
(the “Effectiveness Period”). The Resale Registration Statement when declared effective
(including the documents incorporated therein by reference) will comply as to form in all material
respects with all applicable requirements of the Securities Act and the Exchange Act and will not
contain an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading (and, in the case of any
prospectus contained in such Resale Registration Statement, in the light of the circumstances under
which a statement is made). As soon as practicable following the date that the Resale Registration
Statement becomes effective, but in any event within five Business Days of such date, the
Partnership shall provide the Holders with written notice of the effectiveness of the Resale
Registration Statement.

          (b) Resale Registration Opt-Out. Any Holder may deliver advance written notice (a
“Resale Opt-Out Notice”) to the Partnership requesting that such Holder not be included in
the Resale Registration Statement. Following receipt of a Resale Opt-Out Notice from a Holder, the
Partnership shall not be required to include the Purchased Units of such Holder in the Resale
Registration Statement. The Holders indicated on Schedule 1 hereto shall each be deemed to have
delivered a Resale Opt-Out Notice as of the date hereof.

          (c) Failure To Become Effective. If the Resale Registration Statement required by
Section 2.1(a) does not become or is not declared effective on or before the Target Effective Date,
then the Partnership shall pay each Holder (with respect to the Purchased Units of each such Holder
which are included on such Resale Registration Statement), as liquidated damages and not as a
penalty, (i) for each non-overlapping 30-day period for the first 60 days following the Target
Effective Date, an amount equal to (A) 0.25% times (B) the product of (x) the Purchased Unit Price
times (y) the number of Purchased Units, then held by such Holder and included on such Resale
Registration Statement (such product of (x) and (y) being the “Liquidated Damages
Multiplier”), and (ii) for each non-overlapping 30-day period beginning on the 61st day
following the Target Effective Date, with such payment amount increasing by an additional amount
equal to 0.25% times the Liquidated Damages Multiplier per non-overlapping 30-day period for each
subsequent 60 days (i.e., 0.5% for 61-120 days, 0.75% for 121-180 days, and 1.0% thereafter) up to
a maximum amount equal to 1.0% times the Liquidated Damages Multiplier per non-overlapping 30-day
period (the “Liquidated Damages”); provided, that the aggregate amount of Liquidated
Damages payable by the Partnership per Purchased Unit may not exceed 5.0% of the Purchased Unit
Price. The Liquidated Damages payable pursuant to the immediately preceding sentence shall be
payable within ten Business Days after the end of each such non-overlapping 30-day period. Any
Liquidated Damages shall be paid to each Holder in cash; provided, however, if the Partnership
certifies that it is unable to pay Liquidated Damages

4

 

in cash because such payment will violate a covenant in an existing credit agreement or other
indebtedness, then the Partnership may, in its sole discretion, pay the Liquidated Damages in kind
in the form of the issuance of Common Units, unless otherwise not permitted. Upon any issuance of
Common Units as Liquidated Damages, the Partnership shall promptly prepare and file a supplemental
listing application with the NASDAQ to list such Common Units. The determination of the number of
Common Units to be paid as Liquidated Damages shall be based on the volume-weighted average price
of the Common Units for the ten trading days immediately preceding the date on which the Liquidated
Damages payment is due, less a discount of 2%. The payment of Liquidated Damages under this
Section 2.1(c) and Section 2.1(d) to a Holder shall cease at such time as the Resale Registration
Statement becomes or is declared effective by the Commission or at such time as the securities
included on the Resale Registration Statement are no longer Registrable Securities), and shall be
prorated for any period of less than 30 days in which the Liquidated Damages cease.

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

          (e) Delay Rights. Notwithstanding anything to the contrary contained herein, the
Partnership may, upon written notice to any Selling Holder whose Registrable Securities are
included in the Resale Registration Statement, suspend such Selling Holder’s use of any prospectus
which is a part of the Resale Registration Statement (in which event the Selling Holder shall
discontinue sales of the Registrable Securities pursuant to the Resale Registration Statement but
may settle any previously made sales of Registrable Securities) if (i) the Partnership is pursuing
an acquisition, merger, reorganization, disposition or other similar transaction and the
Partnership determines in good faith that the Partnership’s ability to pursue, consummate or
finance such a transaction would be materially adversely affected by any required disclosure of
such transaction in the Resale Registration Statement or (ii) the Partnership has experienced some
other material non-public event the disclosure of which at such time, in the good faith judgment of
the Partnership, would materially adversely affect the Partnership; provided, however, in no event
shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Resale
Registration Statement for a period that exceeds an aggregate of 60 days in any 180-day period or
105 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement
executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such
information or the termination of the condition described above, the Partnership shall provide
prompt notice to the Selling Holders whose Registrable Securities are included in the Resale
Registration Statement, and shall promptly terminate any suspension of sales it has put into effect
and shall take such other reasonable actions to permit registered sales of Registrable Securities
as contemplated in this Agreement.

          (f) Additional Rights to Liquidated Damages. If (i) the Holders shall be prohibited
from selling their Registrable Securities under the Resale Registration Statement as a

5

 

result of a suspension pursuant to Section 2.1(e) of this Agreement in excess of the periods
permitted therein or (ii) the Resale Registration Statement is filed and declared effective but,
during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for
its intended purpose without being succeeded within 10 days by a post-effective amendment pursuant
thereto, a supplement to the prospectus or a report filed with the Commission pursuant to Section
13(a), 13(c), 14 or 15(d) of the Exchange Act, then until the suspension is lifted or a
post-effective amendment, supplement or report is filed with the Commission and declared effective,
but not including any day on which a suspension is lifted or such amendment, supplement or report
is declared effective, if applicable, the Partnership shall owe the Holder an amount equal to the
Liquidated Damages, following the earlier of (i) the date on which the suspension period exceeded
the permitted period or (ii) the 11th day after the Resale Registration Statement ceased
to be effective or failed to be useable for its intended purposes. All of the provisions in
Section 2.1(c) with respect to the payment of the Liquidated Damages, including but not limited to
the ability to issue additional Common Units in lieu of cash payments, the time period in which
payments are due, and the determination of the number of Common Units to issue as Liquidated
Damages shall be applicable to the Liquidated Damages payable hereunder. For purposes of this
Section 2.1(f), a suspension shall be deemed lifted on the date that notice that the suspension has
been lifted is delivered to the Holders pursuant to Section 3.1 of this Agreement.

          (g) Termination of Rights. Other than as set forth otherwise in this Agreement, a
Holder’s rights (and any transferee’s rights pursuant to Section 2.9) under this Section 2.1,
including rights to Liquidated Damages (other than Liquidated Damages owing but not yet paid),
shall terminate upon the termination of the Effectiveness Period.

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

     Section 2.2 Piggyback Rights.

          (a) Underwritten Offering Piggyback Rights. If the Partnership proposes to file (i) a
registration statement, or (ii) a prospectus supplement to an effective registration statement, so
long as the Corporation is a WKSI at such time or, whether or not the Corporation is a WKSI, so
long as the Registrable Securities were previously included in the underlying shelf Registration
Statement or are included on an effective Resale Registration Statement, or in any case in which
Holders may participate in such offering without the filing of a post-effective amendment, in each
case, for the sale of Common Units in an Underwritten Offering for its own account and/or another
Person, other than (a) a registration relating solely to employee benefit plans, (b) a registration
relating solely to a Rule 145 transaction, or (c) a registration on any registration form which
does not permit secondary sales, then as soon as practicable following the engagement of counsel by
the Partnership to prepare the documents to be used in connection with an Underwritten Offering,
the Partnership shall give notice (including, but not limited to, notification by electronic mail)
of such proposed Underwritten Offering to each Holder owning more than $20.0 million of such Common
Units, calculated on the basis of the Purchased Unit Price, and such notice shall offer such Holder
the opportunity to participate in any Underwritten Offering and to include in such Underwritten
Offering such number of Registrable Securities that

6

 

are Common Units (the “Included Registrable Securities”) as each such Holder may
request in writing, subject to any registration rights existing prior to the Closing Date and
customary underwriter cutbacks; provided, however, that the Partnership shall not be required to
provide such opportunity (i) to any such Holder that does not offer a minimum of $10.0 million of
Registrable Securities (based on the Purchased Unit Price), or (ii) to such Holders if the
Partnership has been advised by the Managing Underwriter that the inclusion of Registrable
Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing
or distribution of the Common Units in the Underwritten Offering, then the amount of Registrable
Securities to be offered for the accounts of Holders shall be determined based on the provisions of
Section 2.2(b). Any notice required to be provided in this Section 2.2(a) to Holders shall be
provided on a Business Day pursuant to Section 3.1 hereof and receipt of such notice shall be
confirmed by the Holder. The Holder will have two Business Days (or one Business Day in connection
with any overnight or bought Underwritten Offering) after notice has been delivered to request in
writing the inclusion of Registrable Securities that are Common Units in the Underwritten Offering.
If no written request for inclusion from a Holder is received within the specified time, each such
Holder shall have no further right to participate in such Underwritten Offering. If, at any time
after giving written notice of its intention to undertake an Underwritten Offering and prior to the
closing of such Underwritten Offering, the Partnership shall determine for any reason not to
undertake or to delay such Underwritten Offering, the Partnership may, at its election, give
written notice of such determination to the Selling Holders and, (x) in the case of a determination
not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any
Included Registrable Securities in connection with such terminated Underwritten Offering, and (y)
in the case of a determination to delay such Underwritten Offering, shall be permitted to delay
offering any Included Registrable Securities for the same period as the delay in the Underwritten
Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for
inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving
written notice to the Partnership of such withdrawal at or prior to the time of pricing of such
Underwritten Offering. Any Holder may deliver written notice (an “Piggyback Opt-Out
Notice”) to the Partnership requesting that such Holder not receive notice from the Partnership
of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any
such Piggyback Opt-Out Notice in writing. Following receipt of an Piggyback Opt-Out Notice from a
Holder (unless subsequently revoked), the Partnership shall not be required to deliver any notice
to such Holder pursuant to this Section 2.2(a) and such Holder shall no longer be entitled to
participate in Underwritten Offerings by the Partnership pursuant to this Section 2.2(a). The
Holders indicated on Schedule 1 hereto shall each be deemed to have delivered an Piggyback Opt-Out
Notice as of the date hereof.

          (b) Priority of Piggyback Rights. If the Managing Underwriter or Underwriters of any
proposed Underwritten Offering advises the Partnership that the total amount of Registrable
Securities that the Selling Holders and any other Persons intend to include in such offering
exceeds the number that can be sold in such offering without being likely to have an adverse effect
on the price, timing or distribution of the Common Units offered or the market for the Common
Units, then the Common Units to be included in such Underwritten Offering shall include the number
of Registrable Securities that are Common Units that such Managing Underwriter or Underwriters
advises the Partnership can be sold without having such adverse effect, with such number to be
allocated (i) first, to the Partnership and, (ii) second, pro rata

7

 

among the Selling Holders who have requested participation in such Underwritten Offering and
any other holder of securities of the Partnership having rights of registration that are neither
expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”).
The pro rata allocations for each Selling Holder who has requested participation in such
Underwritten Offering shall be the product of (A) the aggregate number of Registrable Securities
that are Common Units proposed to be sold in such Underwritten Offering multiplied by (B) the
fraction derived by dividing (x) the number of Registrable Securities that are Common Units owned
on the Closing Date by such Selling Holder by (y) the aggregate number of Registrable Securities
that are Common Units owned on the Closing Date by all Selling Holders plus the aggregate number of
Parity Securities owned on the Closing Date by all holders of Parity Securities that are
participating in the Underwritten Offering.

          (c) Termination of Piggyback Registration Rights. The piggyback rights under Section
2.2 will terminate at the earlier of (i) the time at which a Holder and its Affiliates own less
than $20.0 million of Common Units (based on the Purchased Unit Price) or (ii) the Common Units
cease to be Registrable Securities.

     Section 2.3 Underwritten Offering.

          (a) General Procedures. In connection with any Underwritten Offering under this
Agreement, the Partnership shall be entitled to select the Managing Underwriter or Underwriters in
its sole discretion. In connection with an Underwritten Offering contemplated by this Agreement in
which a Selling Holder participates, each Selling Holder and the Partnership shall be obligated to
enter into an underwriting agreement with the Managing Underwriter or Underwriters which contains
such representations, covenants, indemnities and other rights and obligations as are customary in
underwriting agreements for firm commitment offerings of equity securities. No Selling Holder may
participate in an Underwritten Offering unless such Selling Holder agrees to sell its Registrable
Securities on the basis provided in such underwriting agreement and completes and executes all
questionnaires, powers of attorney, indemnities and other documents reasonably required under the
terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or
all of the representations and warranties by, and the other agreements on the part of, the
Partnership to and for the benefit of such underwriters also be made to and for such Selling
Holder’s benefit and that any or all of the conditions precedent to the obligations of such
underwriters under such underwriting agreement also be conditions precedent to its obligations. No
Selling Holder shall be required to make any representations or warranties to or agreements with
the Partnership or the underwriters other than representations, warranties or agreements regarding
such Selling Holder, its authority to enter into such underwriting agreement and to sell, and its
ownership of the securities being registered on its behalf and its intended method of distribution
and any other representation required by law. If any Selling Holder disapproves of the terms of an
Underwritten Offering, such Selling Holder may elect to withdraw therefrom by notice to the
Partnership and the Managing Underwriter; provided, however, that such withdrawal must be made at
least one Business Day prior to the time of pricing of such Underwritten Offering to be effective.
No such withdrawal or abandonment shall affect the Partnership’s obligation to pay Registration
Expenses.

          (b) Sale Procedures. In connection with its obligations under this Article II, the
Partnership will, as expeditiously as possible:

8

 

               (i) prepare and file with the Commission such amendments and supplements to the
Resale Registration Statement and the prospectus used in connection therewith as may be
necessary to keep the Resale Registration Statement effective for the Effectiveness Period
and as may be necessary to comply with the provisions of the Securities Act with respect
to the disposition of all Registrable Securities covered by the Resale Registration
Statement;

               (ii) furnish to each Selling Holder (A) as far in advance as reasonably practicable
before filing the Resale Registration Statement or any supplement or amendment thereto,
upon request, copies of reasonably complete drafts of all such documents proposed to be
filed (including exhibits and each document incorporated by reference therein to the
extent then required by the rules and regulations of the Commission), and provide each
such Selling Holder the opportunity to object to any information pertaining to such
Selling Holder and its plan of distribution that is contained therein and make the
corrections reasonably requested by such Selling Holder with respect to such information
prior to filing the Resale Registration Statement or supplement or amendment thereto, and
(B) such number of copies of the Resale Registration Statement and the prospectus included
therein and any supplements and amendments thereto as such Selling Holder may reasonably
request in order to facilitate the public sale or other disposition of the Registrable
Securities covered by such Resale Registration Statement;

               (iii) if applicable, use its commercially reasonable efforts to register or qualify
the Registrable Securities covered by the Resale Registration Statement under the
securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably
request; provided, however, that the Partnership will not be required to qualify generally
to transact business in any jurisdiction where it is not then required to so qualify or to
take any action which would subject it to general service of process in any such
jurisdiction where it is not then so subject;

               (iv) promptly notify each Selling Holder, at any time when a prospectus relating
thereto is required to be delivered by any of them under the Securities Act, of (A) the
filing of the Resale Registration Statement or any prospectus or prospectus supplement to
be used in connection therewith, or any amendment or supplement thereto, and, with respect
to such Resale Registration Statement or any post-effective amendment thereto, when the
same has become effective; and (B) the receipt of any written comments from the Commission
with respect to any filing referred to in clause (A) and any written request by the
Commission for amendments or supplements to the Resale Registration Statement or any
prospectus or prospectus supplement thereto;

               (v) immediately notify each Selling Holder, at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of (A) the happening of any
event as a result of which the prospectus or prospectus supplement contained in the Resale
Registration Statement, as then in effect, includes an untrue statement of a material fact
or omits to state any material fact required to be stated therein or necessary to make the
statements therein not misleading (in the case of any

9

 

prospectus contained therein, in the light of the circumstances under which a
statement is made); (B) the issuance or express threat of issuance by the Commission of
any stop order suspending the effectiveness of the Resale Registration Statement, or the
initiation of any proceedings for that purpose; or (C) the receipt by the Partnership of
any notification with respect to the suspension of the qualification of any Registrable
Securities for sale under the applicable securities or blue sky laws of any jurisdiction.
Following the provision of such notice, the Partnership agrees to as promptly as
practicable amend or supplement the prospectus or prospectus supplement or take other
appropriate action so that the prospectus or prospectus supplement does not include an
untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing and to take such other commercially reasonable action as is
necessary to remove a stop order, suspension, threat thereof or proceedings related
thereto;

               (vi) upon request and subject to appropriate confidentiality obligations, furnish to
each Selling Holder copies of any and all transmittal letters or other correspondence with
the Commission or any other governmental agency or self-regulatory body or other body
having jurisdiction (including any domestic or foreign securities exchange) relating to
such offering of Registrable Securities;

               (vii) otherwise use its commercially reasonable efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earnings statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated
thereunder;

               (viii) cause all such Registrable Securities registered pursuant to this Agreement to
be listed on each securities exchange or nationally recognized quotation system on which
similar securities issued by the Partnership are then listed;

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

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

               (xi) if requested by a Selling Holder, (i) incorporate in a prospectus supplement or
post-effective amendment such information as such Selling Holder reasonably requests to be
included therein relating to the sale and distribution of Registrable Securities,
including information with respect to the number of Registrable Securities being offered
or sold, the purchase price being paid therefor and any other terms of the offering of the
Registrable Securities to be sold in such offering; and (ii)

10

 

make all required filings of such prospectus supplement or post-effective amendment
after being notified of the matters to be incorporated in such prospectus supplement or
post-effective amendment; and

               (xii) The Partnership agrees that, if any Holder could reasonably be deemed to be an
“underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with
the Resale Registration Statement and any amendment or supplement thereof, then the
Partnership will reasonably cooperate with such Holder in allowing such Holder to conduct
customary “underwriter’s due diligence” with respect to the Partnership and satisfy its
obligations in respect thereof. In addition, at any Holder’s request, the Partnership
will furnish to such Holder, on the date of the effectiveness of the Resale Registration
Statement and thereafter from time to time on such dates as such Holder may reasonably
request, (A) a “cold comfort” letter, dated such date, from the Partnership’s independent
certified public accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering, addressed
to such Holder, (B) an opinion, dated as of such date, of counsel representing the
Partnership for purposes of the Resale Registration Statement, in form, scope and
substance as is customarily given in an underwritten public offering, including a standard
“10b-5” opinion for such offering, addressed to such Holder and (C) a standard officer’s
certificate from the chief executive officer or chief financial officer, or other officers
serving such functions, of the General Partner addressed to the Holder. Each Selling
Holder, upon receipt of notice from the Partnership of the happening of any event of the
kind described in subsection (v) of Section 2.3(b), shall forthwith discontinue offers and
sales of the Registrable Securities until such Selling Holder’s receipt of the copies of
the supplemented or amended prospectus contemplated by subsection (v) of Section 2.3(b) or
until it is advised in writing by the Partnership that the use of the prospectus may be
resumed and has received copies of any additional or supplemental filings incorporated by
reference in the prospectus, and, if so directed by the Partnership, such Selling Holder
will, or will request the managing underwriter or underwriters, if any, to deliver to the
Partnership (at the Partnership’s expense) all copies in their possession or control,
other than permanent file copies then in such Selling Holder’s possession, of the
prospectus covering such Registrable Securities current at the time of receipt of such
notice.

         Section 2.4 Cooperation by Holders. The Partnership shall have no obligation to
include Registrable Securities of a Holder in the Resale Registration Statement who has failed to
timely furnish such information that the Partnership determines, after consultation with its
counsel, is reasonably required in order for the registration statement or prospectus supplement,
as applicable, to comply with the Securities Act, including the execution of the initial Selling
Unitholder Notice and Questionnaire attached at Exhibit A to this Agreement by the date specified
thereon.

         Section 2.5 Restrictions on Public Sale by Holders of Registrable Securities. For so
long as the Purchased Units are Registrable Securities, each Holder agrees that it will not sell
any Common Units or other equity securities of the Partnership for a period of up to 60 days
following the pricing date of an Underwritten Offering of equity securities by the Partnership;
provided, however, that the duration of the foregoing restrictions shall be no longer than the

11

 

duration of the shortest restriction imposed by the underwriters on the officers, directors or
any Affiliate of the Partnership. In addition, the provisions of this Section 2.5 shall not apply
with respect to a Holder that (i) owns less than $20.0 million of Registrable Securities based on
the Purchased Unit Price, or (ii) has delivered a Piggyback Opt-Out Notice or a Resale Opt-Out
Notice to the Partnership pursuant to Section 2.2 hereof. Subject to such Holder’s compliance with
its obligations under the U.S. federal securities laws and its internal policies: (a) Holder, for
purposes hereof, shall not be deemed to include any employees, subsidiaries or Affiliates that are
effectively walled off by appropriate “Chinese Wall” information barriers approved by Holder’s
legal or compliance department (and thus have not been privy to any information concerning this
transaction) (a “Walled Off Person”) and (b) the foregoing covenants in this paragraph shall not
apply to any transaction by or on behalf of Holder that was effected by a Walled Off Person in the
ordinary course of trading without the advice or participation of Holder or receipt of confidential
or other information regarding this transaction provided by Holder to such entity.

     Section 2.6 Expenses.

          (a) Expenses. The Partnership will pay all reasonable Registration Expenses as
determined in good faith. Each Selling Holder shall pay its pro rata share of all Selling Expenses
in connection with any sale of its Registrable Securities hereunder. In addition, except as
otherwise provided in Section 2.7 hereof, the Partnership shall not be responsible for legal fees
incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

          (b) Certain Definitions. “Registration Expenses” means all expenses incident
to the Partnership’s performance under or compliance with this Agreement to effect the registration
of Registrable Securities on the Resale Registration Statement pursuant to Section 2.1 and the
disposition of such Registrable Securities, including, without limitation, all registration,
filing, securities exchange listing and NASDAQ fees, all registration, filing, qualification and
other fees and expenses of complying with securities or blue sky laws, fees of the Financial
Industry Regulatory Authority, fees of transfer agents and registrars, all word processing,
duplicating and printing expenses, any transfer taxes and the fees and disbursements of counsel and
independent public accountants for the Partnership, including the expenses of any special audits or
“cold comfort” letters required by or incident to such performance and compliance. “Selling
Expenses” means all underwriting fees, discounts and selling commissions or similar fees or
arrangements allocable to the sale of the Registrable Securities.

     Section 2.7 Indemnification.

          (a) By the Partnership. In the event of a registration of any Registrable Securities
under the Securities Act pursuant to this Agreement, the Partnership will indemnify and hold
harmless each Selling Holder thereunder, its directors, officers, employees and agents and each
Person, if any, who controls such Selling Holder and its directors, officers, employees or agents
(collectively, the “Selling Holder Indemnified Persons”), against any losses, claims,
damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively,
“Losses”), joint or several, to which such Selling Holder Indemnified Person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions
or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact (in the case

12

 

of any prospectus, in light of the circumstances under which such statement is made) contained
in the Resale Registration Statement, any preliminary prospectus, prospectus supplement, free
writing prospectus or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein (in the case of a
prospectus, in light of the circumstances under which they were made) not misleading, and will
reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such Loss or actions or
proceedings; provided, however, that the Partnership will not be liable in any such case if and to
the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information furnished by such
Selling Holder Indemnified Person in writing specifically for use in the Resale Registration
Statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified
Person, and shall survive the transfer of such securities by such Selling Holder.

          (b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to
indemnify and hold harmless the Partnership, the General Partner and each of their respective
directors, officers, employees and agents and each Person, if any, who controls the Partnership
within the meaning of the Securities Act or of the Exchange Act, and its directors, officers,
employees and agents, to the same extent as the foregoing indemnity from the Partnership to the
Selling Holders, but only with respect to information regarding such Selling Holder furnished in
writing by or on behalf of such Selling Holder expressly for inclusion in the Resale Registration
Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final
prospectus contained therein, or any amendment or supplement thereof; provided, however, that the
liability of each Selling Holder shall not be greater in amount than the dollar amount of the
proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the
Registrable Securities giving rise to such indemnification.

          (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party hereunder, notify the indemnifying party in writing thereof,
but the omission so to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party other than under this Section 2.7. In any action brought
against any indemnified party, it shall notify the indemnifying party of the commencement thereof.
The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to
assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified
party and, after notice from the indemnifying party to such indemnified party of its election so to
assume and undertake the defense thereof, the indemnifying party shall not be liable to such
indemnified party under this Section 2.7 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable costs of
investigation and of liaison with counsel so selected; provided, however, that, (i) if the
indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the
indemnified party or (ii) if the defendants in any such action include both the indemnified party
and the indemnifying party and counsel to the indemnified party shall have concluded that there may
be reasonable defenses available to the indemnified

13

 

party that are different from or additional to those available to the indemnifying party, or
if the interests of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying party, then the indemnified party shall have the right to select a separate
counsel and to assume such legal defense and otherwise to participate in the defense of such
action, with the reasonable expenses and fees of such separate counsel and other reasonable
expenses related to such participation to be reimbursed by the indemnifying party (provided
appropriate documentation for such expense is also submitted with such notice) as incurred;
provided however, that the indemnified party will be required to repay the
indemnifying party any amounts paid to it for which it is determined the indemnified party was not
otherwise entitled within five calendar days of such determination. Notwithstanding any other
provision of this Agreement, no indemnifying party shall settle any action brought against any
indemnified party with respect to which such indemnified party is entitled to indemnification
hereunder without the consent of the indemnified party, unless the settlement thereof imposes no
liability or obligation on, and includes a complete and unconditional release from all liability
of, the indemnified party.

          (d) Contribution. If the indemnification provided for in this Section 2.7 is held by
a court or government agency of competent jurisdiction to be unavailable to any indemnified party
or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Loss in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of such indemnified party
on the other in connection with the statements or omissions which resulted in such Losses, as well
as any other relevant equitable considerations; provided, however, that in no event shall such
Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of
proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable
Securities giving rise to such indemnification. The relative fault of the indemnifying party on
the one hand and the indemnified party on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact has been made by, or relates to, information supplied by
such party, and the parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this paragraph were to be determined by pro rata
allocation or by any other method of allocation which does not take account of the equitable
considerations referred to herein. The amount paid by an indemnified party as a result of the
Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and
other expenses reasonably incurred by such indemnified party in connection with investigating or
defending any Loss which is the subject of this paragraph. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who is not guilty of such fraudulent misrepresentation.

          (e) Other Indemnification. The provisions of this Section 2.7 shall be in addition to
any other rights to indemnification or contribution which an indemnified party may have pursuant to
law, equity, contract or otherwise.

     Section 2.8 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the Registrable

14

 

Securities to the public without registration, the Partnership agrees to use its commercially
reasonable efforts to:

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

          (b) File with the Commission in a timely manner all reports and other documents required of
the Partnership under the Securities Act and the Exchange Act at all times from and after the date
hereof; and

          (c) So long as a Holder owns any Registrable Securities, furnish, unless otherwise available
at no charge by access electronically to the Commission’s EDGAR filing system, to such Holder
forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and
such other reports and documents so filed with the Commission as such Holder may reasonably request
in availing itself of any rule or regulation of the Commission allowing such Holder to sell any
such securities without registration.

If the Partnership fails for any reason to comply with the provisions of this Section 2.8 during
the period beginning on the date which is six months from the Closing Date and ending one year from
the Closing Date which prohibits a Holder from selling Purchased Units, then held by such Holder
pursuant to Rule 144 under the Securities Act for more than ten (10) days in the aggregate, then
the Partnership shall pay to each such Holder an amount equal to 0.25% times the Liquidated Damages
Multiplier for each 30 days in excess of such 5 days during which such Holder is unable to sell the
Purchased Units, with such payment amount increasing by an additional amount equal to 0.25% times
the Liquidated Damages Multiplier per additional 30 days up to a maximum of 1% times the Liquidated
Damages Multiplier; provided, that the aggregate amount of Liquidated Damages payable by the
Partnership per Purchased Unit may not exceed 5.0% of the Purchased Unit Price. All of the
provisions in Section 2.1(b) with respect to the payment of the Liquidated Damages, including but
not limited to the ability to issue additional Common Units in lieu of cash payments, the time
period in which payments are due, and the determination of the number of Common Units to issue as
Liquidated Damages shall be applicable to the Liquidated Damages payable hereunder.

     Section 2.9 Transfer or Assignment of Registration Rights. The rights to cause the
Partnership to register Registrable Securities granted to the Purchasers by the Partnership under
this Article II will be transferable or assignable by each Purchaser to an Affiliate of such
Purchaser or to a transferee or assignee of Registrable Securities, provided (a) the amount of
Registrable Securities transferred or assigned to a Person who is not an Affiliate must represent
at least $20.0 million, based on the Purchased Unit Price, (b) the Partnership is given written
notice prior to any such transfer or assignment, stating the name and address of each such
transferee and identifying the securities with respect to which such registration rights are being
transferred or assigned, and (c) each such transferee agrees in writing to undertake responsibility
for its portion of the obligations of such Purchaser under this Agreement.

     Section 2.10 Limitation on Subsequent Registration Rights. From and after the date
hereof, the Partnership shall not, without the prior written consent of the Holders of a majority
of

15

 

the outstanding Registrable Securities, enter into any agreement with any current or future
holder of any securities of the Partnership that would allow such current or future holder to
require the Partnership to include securities in any registration statement filed by the
Partnership on a basis other than pari passu with, or expressly subordinate to, the priority rights
set forth in Section 2.2(b) granted to the Holders of Registrable Securities hereunder.

     Section 3.2 Successor and Assigns. This Agreement shall inure to the benefit of and
be binding upon the successors and assigns of each of the parties, including subsequent Holders of
Registrable Securities to the extent permitted herein.

     Section 3.3 Assignment of Rights. All or any portion of the rights and obligations of
any Purchaser under this Agreement may be transferred or assigned by such Purchaser in accordance
with Section 2.9 hereof.

     Section 3.4 Recapitalization, Exchanges, Etc. Affecting the Units. The provisions of
this Agreement shall apply to the full extent set forth herein with respect to any and all units of
the Partnership or any successor or assign of the Partnership (whether by merger, consolidation,
sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution
of, the Registrable Securities, and shall be appropriately adjusted for combinations, unit splits,
recapitalizations and the like occurring after the date of this Agreement.

     Section 3.5 Aggregation of Restricted Units. All Registrable Securities held or
acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose
of determining the availability of any rights and applicability of any obligations under this
Agreement.

     Section 3.6 Specific Performance. Damages in the event of breach of this Agreement by
a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that
each such Person, in addition to and without limiting any other remedy or right it may have, will
have the right to an injunction or other equitable relief in any court of competent jurisdiction,
enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of
the parties hereto hereby waives any and all defenses it may have on the ground of lack of
jurisdiction or competence of the court to grant such an injunction or other equitable relief. The
existence of this right will not preclude any such Person from pursuing any other rights and
remedies at law or in equity which such Person may have.

     Section 3.7 Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of which counterparts,
when so executed and delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Agreement.

     Section 3.8 Headings. The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof.

     Section 3.9 Governing Law. The Laws of the State of Texas shall govern this Agreement
without regard to principles of conflicts of Laws that would apply the substantive law of some
other jurisdiction.

     Section 3.10 Severability of Provisions. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition or unenforceability without invalidating the remaining provisions
hereof or affecting or impairing the validity or enforceability of such provision in any other
jurisdiction.

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

     Section 3.12 Amendment. This Agreement may be amended only by means of a written
amendment signed by the Partnership and the Holders of a majority of the then outstanding
Registrable Securities; provided, however, that no such amendment shall materially and adversely
affect the rights of any Holder hereunder without the consent of such Holder.

     Section 3.13 No Presumption. If any claim is made by a party relating to any
conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion
shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a
particular party or its counsel.

     Section 3.14 Obligations Limited to Parties to Agreement. Each of the Parties hereto
covenants, agrees and acknowledges that no Person other than the Purchasers (and their permitted
assignees) and the Partnership shall have any obligation hereunder and that, notwithstanding that
one or more of the Purchasers may be a corporation, partnership or limited liability company, no
recourse under this Agreement or under any documents or instruments delivered in connection
herewith or therewith shall be had against any former, current or future director, officer,
employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of
the Purchasers or any former, current or future director, officer, employee, agent, general or
limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the
enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any
applicable Law, it being expressly agreed and acknowledged that

19

 

no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by
any former, current or future director, officer, employee, agent, general or limited partner,
manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future
director, officer, employee, agent, general or limited partner, manager, member, stockholder or
Affiliate of any of the foregoing, as such, for any obligations of the Purchasers under this
Agreement or any documents or instruments delivered in connection herewith or therewith or for any
claim based on, in respect of or by reason of such obligation or its creation, except in each case
for any assignee of a Purchaser hereunder.

     Section 3.15 Interpretation. Article, Exhibit and Section references in this
Agreement are references to the corresponding Article and Section to this Agreement, unless
otherwise specified. All references to instruments, documents, contracts and agreements are
references to such instruments, documents, contracts and agreements as the same may be amended,
supplemented and otherwise modified from time to time, unless otherwise specified. The word
“including” shall mean “including but not limited to.” Whenever any determination, consent or
approval is to be made or given by a Purchaser under this Agreement, such action shall be in such
Purchaser’s sole discretion unless otherwise specified.

     Section 3.16 Equal Treatment of Purchasers. Neither the Partnership nor any of its
Affiliates shall, directly or indirectly, offer to pay, pay or cause to be paid any consideration,
whether by way of interest, fee, payment for the redemptions or exchange of Registrable Securities,
or otherwise, to any holder of Registrable Securities for or as an inducement to, or in connection
with solicitation of, any consent, waiver or amendment of any terms or provisions of the
Registrable Securities or this Agreement or any of the other agreements referred to in this
Agreement unless such consideration is offered to all Holders.
