no Partner shall be required to make any Additional Capital Contributions on or after the date of
this Agreement. In the event the General Partner determines for any quarter there exists an

debt service and a reasonable contingency reserve (but excluding for purposes of clarification cash

Partners to make Additional

expenditures for Expansion Projects funded exclusively out of Capital Contributions made by the
Partners (the “Expansion Costs”) and the related funding of Expansion Cash Calls shall be borne
solely by the Partners as set forth below in this Section 4.03, unless agreed to otherwise by all
of such Partners, in an amount equal to the product of (A) the aggregate amount of the Expansion
Costs multiplied by (B) a fraction, the numerator of

such participating Partner and the denominator of which is the aggregate Percentage Interest of all
of the participating Partners.

          (b) The General Partner shall provide written notice to the Partners of the date contributions
are due, which date shall be not less than 30 nor more than 90 Days following the date of such
notice, the aggregate amount of the Capital Contribution required and each Partner’s share thereof,
and setting forth in reasonable detail the proposed Expansion Project and Expansion Costs
associated therewith. Each Partner shall advise the General Partner in writing within 20 Days
whether it elects to make an Expansion Capital Contribution.

Expansion Project within 20 Days after notice of such Expansion Cash Call, then (i) the EPD Party
may make additional Capital Contributions of cash in an amount up to the product of its Percentage
Interest and the amount of the applicable Expansion Cash Call and (ii) the DEP Party shall make
additional Capital Contributions of cash equal to the excess of the Expansion Cash Call over
amounts elected to be contributed by the EPD Party under clause (i) immediately preceding.

          (d) If the DEP Party elects not to make an Expansion Capital Contribution with respect to an
Expansion Project within 20 Days after notice of such Expansion Cash Call, then the EPD Party may
make Expansion Capital Contributions of cash in an amount equal to 100% of such Expansion Cash
Call. Notwithstanding the foregoing, the DEP Party may subsequently elect to make an Expansion
Capital Contribution associated with any Expansion Project by paying to the EPD Party, within 90
Days following the applicable Initial Commencement Date, an amount equal to the product of (i) the
sum of (A) the amount of the Expansion Cash Call, plus (B) the effective cost of capital to the EPD
Party based on the weighted average interest rate of the EPD Party incurred for borrowings during
such period as determined by its Board of Directors in its reasonable judgment, minus (C) any
amounts, if any, distributed to the EPD Party with respect to its additional Capital Contributions
associated with such Expansion Project pursuant to the limited liability company agreement of
Enterprise Texas
multiplied by the Percentage Interest of the DEP Party, and (ii) the Percentage Interest of
the DEP Party. If the DEP Party makes a payment pursuant to this Section 4.03(d), then (1) the DEP
Party shall be deemed to make a cash Capital Contribution to the Partnership in an amount equal to
such payment and (2) the Partnership shall be deemed to make a cash distribution to the EPD Party
in an amount equal to such payment.

     4.04 Advances by Partners. If the Partnership does not have sufficient cash to pay its
obligations, the General Partner, or any Limited Partner(s) that may agree to do so with the
General Partner’s consent, may advance all or part of the needed funds to or on behalf of the
Partnership. Payment by the General Partner on account of liability as a matter of law for
Partnership obligations is deemed to be an advance under this Section 4.03. An advance described in
this Section 4.03 constitutes a loan from the Partner to the Partnership, bears interest at a rate
determined by the General Partner (and, if applicable, the Limited Partner making the advance) from
the date of the advance until the date of payment, and is not a Capital Contribution.

10

 

     4.05 Capital Accounts. A capital account shall be established and maintained for each
Partner. Each Partner’s capital account (a) shall be increased by (i) the amount of money
contributed by that Partner to the Partnership, (ii) the fair market value of property contributed
by that Partner to the Partnership (net of liabilities secured by the contributed property that the
Partnership is considered to assume or take subject to under section 752 of the Code), and (iii)
allocations to that Partner of Partnership income and gain (or items of income and gain), including
income and gain exempt from tax and income and gain described in Treas. Reg. §
1.704-1(b)(2)(iv)(g), but excluding income and gain described in Treas. Reg. § 1.704-1(b)(4)(i),
and (b) shall be decreased by (i) the amount of money distributed to that Partner by the
Partnership, (ii) the fair market value of property distributed to that Partner by the Partnership
(net of liabilities secured by the distributed property that the Partner is considered to assume or
take subject to under section 752 of the Code), (iii) allocations to that Partner of expenditures
of the Partnership described in section 705(a)(2)(B) of the Code, and (iv) allocations of
Partnership loss and deduction (or items of loss and deduction), including loss and deduction
described in Treas. Reg. § 1.704-1(b)(2)(iv)(g), but excluding items described in clause (b)(iii)
above and loss or deduction described in Treas. Reg. § 1.704-1(b)(4)(i) or § 1.704-1(b)(4)(iii).
The Partners’ capital accounts also shall be maintained and adjusted as permitted by the provisions
of Treas. Reg. § 1.704-1(b)(2)(iv)(f) and as required by the other provisions of Treas. Reg. §§
1.704-1(b)(2)(iv) and 1.704-1(b)(4), including adjustments to reflect the allocations to the
Partners of depreciation, depletion, amortization, and gain or loss as computed for book purposes
rather than the allocation of the corresponding items as computed for tax purposes, as required by
Treas. Reg. § 1.704-1(b)(2)(iv)(g). A Partner that has more than one Partnership Interest shall
have a single capital account that reflects all its Partnership Interests, regardless of the class
of Partnership Interests owned by that Partner and regardless of the time or manner in which those
Partnership Interests were acquired.

ARTICLE V:ALLOCATIONS AND DISTRIBUTIONS

     5.01 Allocations.

          (a) General. After giving effect to the special allocations set forth in Section 5.01(b), for
purposes of maintaining the capital accounts and in determining the rights of the Partners among
themselves, all items of income, gain, loss and deduction of the Partnership shall be allocated and
charged to the Partners’ capital accounts in accordance with their respective Percentage Interests.

          (b) Special Allocations. Notwithstanding any other provisions of this Section 5.01, the
following special allocations shall be made prior to making any allocations provided for in 5.01(a)
above:

     (i) Minimum Gain Chargeback. Notwithstanding any other provision hereof to the
contrary, if there is a net decrease in Minimum Gain (as generally defined under
Treas. Reg. § 1.704-1 or § 1.704-2) for a taxable year (or if there was a net
decrease in Minimum Gain for a prior taxable year and the Partnership did not have
sufficient amounts of income and gain during prior years to allocate among the
Partners under this subsection 5.01(b)(i), then items of income and gain shall be
allocated to each Partner in an amount equal to such Partner’s share

11

 

of the net
decrease in such Minimum Gain (as determined pursuant to Treas. Reg. §
1.704-2(g)(2)). It is the intent of the Partners that any allocation pursuant to
this subsection 5.01(b)(i) shall constitute a “minimum gain chargeback” under Treas.
Reg. § 1.704-2(f) and shall be interpreted consistently therewith.

     (ii) Partner Nonrecourse Debt Minimum Gain Chargeback. Notwithstanding any
other provision of this Article 5, except subsection 5.01(b)(i), if there is a net
decrease in Partner Nonrecourse Debt Minimum Gain (as generally defined under Treas.
Reg. § 1.704-1 or § 1.704-2), during any taxable year, any Partner who has a share
of the Partner Nonrecourse Debt Minimum Gain shall be allocated such amount of
income and gain for such year (and subsequent years, if necessary) determined in the
manner required by Treas. Reg. § 1.704-2(i)(4) as is necessary to meet the
requirements for a chargeback of Partner Nonrecourse Debt Minimum Gain.

     (iii) Priority Allocations. Items of Partnership gross income or gain for the
taxable period shall be allocated to the Partners until the cumulative amount of
such items allocated to each Partner pursuant to this Section 5.01(b)(iii) for the
current and all previous taxable years equals the cumulative amount of distributions
made to such Partner pursuant to Section 5.02(a) for the current and all previous
taxable years.

     (iv) Qualified Income Offset. Except as provided in subsection 5.01(b)(i) and
(ii) hereof, in the event any Partner unexpectedly receives any
adjustments, allocations or distributions described in Treas. Reg. Sections
1.704-1(b)(2)(i)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items
of Partnership income and gain shall be specifically allocated to such Partner in an
amount and manner sufficient to eliminate, to the extent required by the Allocation
Regulations, the deficit balance, if any, in its adjusted capital account created by
such adjustments, allocations or distributions as quickly as possible.

     (v) Gross Income Allocations. In the event any Partner has a deficit balance
in its adjusted capital account at the end of any Partnership taxable period, such
Partner shall be specially allocated items of Partnership gross income and gain in
the amount of such excess as quickly as possible; provided, that an allocation
pursuant to this subsection 5.01(b)(v) shall be made only if and to the extent that
such Partner would have a deficit balance in its adjusted capital account after all
other allocations provided in this Section 5.01 have been tentatively made as if
subsection 5.01(b)(v) were not in the Agreement.

     (vi) Partnership Nonrecourse Deductions. Partnership Nonrecourse Deductions
(as determined under Treas. Reg. Section 1.704-2(c)) for any fiscal year shall be
allocated among the Partners in proportion to their Partnership Interests.

     (vii) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions (as
defined under Treas. Reg. Section 1.704-2(i)(2)) shall be allocated

12

 

pursuant to
Treas. Reg. Section 1.704-2(i) to the Partner who bears the economic risk of loss
with respect to the partner nonrecourse debt to which it is attributable.

     (viii) Code Section 754 Adjustment. To the extent an adjustment to the
adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of
the Code is required, pursuant to the Allocation Regulations, 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 Partners in a manner
consistent with the manner in which their capital accounts are required to be
adjusted pursuant to the Allocation Regulations.

     (ix) Curative Allocation. The special allocations set forth in subsections
5.01(b)(i), (ii) and (iv)-(vii) (the “Regulatory Allocations”) are intended to
comply with the Allocation Regulations. Notwithstanding any other provisions of
this Section 5.01, the Regulatory Allocations shall be taken into account in
allocating items of income, gain, loss and deduction among the Partners such that,
to the extent possible, the net amount of allocations of such items and the
Regulatory Allocations to each Partner shall be equal to the net amount that would
have been allocated to each Partner if the Regulatory Allocations had not occurred.

          (c) For federal income tax purposes, except as otherwise required by the Code, the Allocation
Regulations or the following sentence, each item of Partnership income, gain, loss, deduction and
credit shall be allocated among the Partners in the same manner as corresponding items are
allocated in Sections 5.01(a) and (b). Notwithstanding any provisions contained herein to the
contrary, solely for federal income tax purposes, items of income, gain, depreciation, gain or loss
with respect to property contributed or deemed contributed to the Partnership by a Partner shall be
allocated so as to take into account the variation between the Partnership’s tax basis in such
contributed property and its Carrying Value in the manner provided under Section 704(c) of the Code
and Treas. Reg. § 1.704-3(d) (i.e. the “remedial method”).

     5.02 Distributions.

          (a) At least quarterly prior to commencement of winding up under Section 11.02, the General
Partner shall determine in its reasonable judgment to what extent (if any) the Partnership’s cash
on hand, exceeds its current and anticipated needs, including, without limitation, for operating
expenses, debt service, acquisitions, and a reasonable contingency reserve. If such an excess
exists, the General Partner shall cause the Partnership to distribute to the Partners, in
accordance with their respective Distribution Ratios, an amount in cash equal to that excess on or
before the date 30 days following the end of each such fiscal quarter.

          (b) From time to time the General Partner also may cause property of the Partnership other
than cash to be distributed to the Partners, which distribution must be made in accordance with
Section 5.02(a) and may be made subject to existing liabilities and obligations.

13

 

Immediately prior
to such a distribution, the capital accounts of the Partners shall be adjusted as provided in
Treas. Reg. § 1.704-1(b)(2)(iv)(f).

          (c) Any Person dealing with the Partnership, other than a Limited Partner, may rely on the
authority of the General Partner in taking any action in the name of the Partnership without
inquiry into the provisions of this Agreement or compliance with it, regardless of whether that
action actually is taken in accordance with the provisions of this Agreement.

     6.02 Compensation. The General Partner is not entitled to compensation for its services as
General Partner, but it is entitled to be reimbursed for out-of-pocket costs and expenses incurred

ONLY IN THE CASE OF BAD FAITH, GROSS NEGLIGENCE, OR BREACH OF THE PROVISIONS OF THIS AGREEMENT, BUT
NOT OTHERWISE. The General Partner shall devote such time and effort to the Partnership business
and operations as is necessary to promote fully the interests of the Partnership; however, the
General Partner need not devote full time to Partnership business.

          (b) Subject to the other provisions of this Agreement, the General Partner and each Limited
Partner at any time and from time to time may engage in and possess interests in other business
ventures of any and every type and description, independently or with others,
including ones in competition with the Partnership, with no obligation to offer to the
Partnership or any other Partner the right to participate in those activities.

          (c) The Partnership may transact business with any Partner or affiliate of a Partner, provided
the terms of the transactions are no less favorable than those the Partnership could obtain from
unrelated third parties.

     6.04 Indemnification. To the fullest extent permitted by applicable law, on request by the
Person indemnified the Partnership shall indemnify the General Partner, its affiliates, and their
respective officers, directors, partners, employees, and agents and hold them harmless from and

INCLUDING THE PERSON INDEMNIFIED’S SOLE, PARTIAL, OR CONCURRENT NEGLIGENCE, and on request by the

including, without limitation, filings of the type described in Section 2.05. This power of
attorney is irrevocable and is coupled with an interest. On request by the General Partner (or the

Person other than another Partner, except for disclosures (a) compelled by law (but the Partner
must notify the General Partner promptly of any request for that information, before disclosing it
if practicable), (b) to advisers or representatives of the Partner, but only if the recipients have

shall be deemed to have consented to or approved the action set forth in the request.

16

investments by its affiliates.

ARTICLE X: WITHDRAWAL, BANKRUPTCY, ETC. OF GENERAL PARTNER

     10.01 Withdrawal, Bankruptcy, Removal Etc. of General Partner.

          (a) Except as provided in Section 10.01(d), the General Partner agrees that it will not
withdraw from the Partnership as a general partner. If the General Partner withdraws from the
Partnership in violation of this covenant, the withdrawal is effective on the 90th day following
notice of the withdrawal to all Limited Partners, or such later date as the notice may specify. On
a withdrawal in violation of this Section 10.01(a), the Partnership’s remedies shall be limited to
the recovery of monetary damages arising from such violation, it being understood that neither the
Partnership nor any Limited Partner shall have the right, through specific performance or
otherwise, to prevent the General Partner from withdrawing in violation of this Agreement.

          (b) The General Partner shall notify each Limited Partner that an event of the type described
in Section 17-402(a)(4), (5), or (7)-(12) of the Act has occurred with respect to it on or before
the fifth Business Day after that occurrence.

          (c) Following any notice that the General Partner is withdrawing (other than pursuant to
Section 10.01(d)), a Required Interest by written consent may select a new General Partner. The
Person selected shall be admitted to the Partnership as the General Partner effective
immediately prior to the existing General Partner’s ceasing to be the General Partner with a
Percentage Interest that the Limited Partners making the selection specify, but only if the new
General Partner has made a Capital Contribution in an amount the Limited Partners making the

18

 

selection specify and has executed and delivered to the Partnership a document including the new
General Partner’s notice address and its agreement to be bound by this Agreement. Notwithstanding
the foregoing provisions of this Section 10.01(c), for the right to select a new General Partner to
be exercised, the Partnership must receive a favorable opinion of the Partnership’s legal counsel
or of other legal counsel acceptable to the Limited Partners making the selection to the effect
that the selection and admission (if any) will not result in (i) the loss of limited liability of
any Limited Partner or (ii) the Partnership’s being treated as an association taxable as a
corporation for federal income tax purposes.

          (d) The General Partner may be removed by a written consent of Partners holding a majority of
the Distribution Ratios. The General Partner may not be removed if such removal would result in
the termination or dissolution of the Partnership under applicable law. The new General Partner
shall not be required to make any Capital Contributions to the Partnership, shall not have a
Percentage Interest or be entitled to any distributions from the Partnership pursuant to Section
5.02. The new General Partner shall execute and deliver to the Partnership a document including the
new General Partner’s notice address and its agreement to be bound by this Agreement. The General
Partner shall not be removed unless and until a new, successor General Partner has been identified
and such successor General Partner has been admitted to the Partnership. The Partners agree to
execute any amendments to this Agreement and take any other actions required to effect the changes
specified in this Section 10.01(d).

     10.02 Conversion of Interest. Simultaneously with the General Partner’s ceasing to be General
Partner following the admission of a new General Partner pursuant to Section 10.01(c) or (d), the
former General Partner’s Partnership Interest as the General Partner automatically is converted
into that of a Limited Partner having a Percentage Interest equal to the Percentage Interest of the
former General Partner as the General Partner immediately prior to its ceasing to be the General
Partner, and the General Partner automatically is admitted to the Partnership as a Limited Partner.

ARTICLE XI: DISSOLUTION, LIQUIDATION, AND TERMINATION

     11.01 Dissolution. The Partnership shall dissolve and its business and affairs shall be wound
up on the first to occur of the following:

          (a) the written consent of the General Partner and a Required Interest;

          (b) the date set forth in Section 2.06;

          (c) the General Partner’s ceasing to be the General Partner as described in Section 10.01(a)
or (d), unless a new General Partner is selected and admitted as provided in Section 10.01(c) or
(d);

          (d) the entry of a decree of judicial dissolution under Section 17-802 of the Act;

          (e) any other event causing dissolution as described in Section 17-801 of the Act (other than
an event described in Section 17-402(a)(4) or (10) of the Act, except as provided in Section
11.01(c));

19

 

provided, however, that if dissolution occurs due to an “event of withdrawal” (as defined in the
Act) with respect to the General Partner and a new General Partner is being admitted pursuant to
Section 10.01(c), the Partnership automatically shall be reconstituted and the new General Partner
shall, and hereby agrees to, carry on the business of the Partnership.

     11.02 Liquidation and Termination. On dissolution of the Partnership, unless it is
reconstituted and continued as provided in Section 11.01, the General Partner shall act as
liquidator or may appoint one or more other Persons as liquidator; provided, however, that if the
Partnership dissolves on account of an event of the type described in Section 17-402(a)(4)-(12) of
the Act with respect to the General Partner, the liquidator shall be one or more Persons selected
in writing by a Required Interest. The liquidator shall proceed diligently to wind up the affairs
of the Partnership and make final distributions as provided in this Agreement. The costs of
liquidation shall be borne as a Partnership expense. Until final distribution, the liquidator shall
continue to operate the Partnership properties with all of the power and authority of the General
Partner. The steps to be accomplished by the liquidator are as follows:

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

          (b) the liquidator shall pay from Partnership funds all of the debts and liabilities of the
Partnership (including, without limitation, all expenses incurred in liquidation and any advances
described in Section 4.03) or otherwise make adequate provision for them (including, without
limitation, the establishment of a cash escrow fund for contingent liabilities in such amount and
for such term as the liquidator may reasonably determine); and

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

          (i) the liquidator may sell any or all Partnership property, including to
Partners, and any resulting gain or loss from each sale shall be computed and
allocated to the capital accounts of the Partners;

          (ii) with respect to all Partnership property that has not been sold, the fair
market value of that property shall be determined and the capital accounts of the
Partners shall be adjusted to reflect the manner in which the unrealized income,
gain, loss, and deduction inherent in property that has not been reflected
in the capital accounts previously would be allocated among the Partners if
there were a taxable disposition of that property for the fair market value of that
property on the date of distribution; and

          (iii) Partnership property shall be distributed among the Partners in
accordance with the positive capital account balances of the Partners, as determined
after taking into account all capital account adjustments for the taxable year of
the Partnership during which the liquidation of the Partnership

20

 

occurs (other than
those made by reason of this clause (iii)); and those distributions shall be made by
the end of the taxable year of the Partnership during which the liquidation of the
Partnership occurs (or, if later, 90 days after the date of the liquidation).

All distributions in kind to the Partners shall be made subject to the liability of each
distributee for its allocable share of costs, expenses, and liabilities previously incurred or for
which the Partnership has committed prior to the date of termination and those costs, expenses, and
liabilities shall be allocated to the distributee under this Section 11.02. The distribution of
cash and/or property to a Partner in accordance with the provisions of this Section 11.02
constitutes a complete return to the Partner of its Capital Contributions and a complete
distribution to the Partner of its Partnership Interest and all the Partnership’s property and
constitutes a compromise to which all Partners have consented within the meaning of Section
17-502(b)(1) of the Act. To the extent that a Partner returns funds to the Partnership, it has no
claim against any other Partner for those funds.

     11.03 Termination. On completion of the distribution of Partnership assets as provided in
this Agreement, the Partnership is terminated, and the General Partner (or such other Person or
Persons as the Act may require or permit) shall cause the cancellation of the Certificate and any
filings made as provided in Section 2.05 and shall take such other actions as may be necessary to
terminate the Partnership.

ARTICLE XII: GENERAL PROVISIONS

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

     12.02 Notices. All notices, requests, or consents provided for or permitted to be given under
this Agreement must be in writing and must be given either by depositing that writing in the United
States mail, addressed to the recipient, postage paid, and registered or certified with return
receipt requested or by delivering that writing to the recipient in person, by courier, or by
facsimile transmission. A notice, request, or consent given under this Agreement is effective on
receipt at the address of the Person to receive it. All notices, requests, and consents to be sent
to a Partner must be sent to or made at the addresses given for that Partner on Exhibit A or in the
instrument described in Sections 10.01(c) and (d), or such other address as that Partner may
specify by notice to the other Partners. Any notice, request, or consent to the Partnership must be
given to the General Partner.

Partners and their affiliates relating to the Partnership and supersedes all prior contracts or
agreements with respect to the Partnership, whether oral or written.

     12.04 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any
breach or default by any Person in the performance by that Person of its obligations with respect
to the Partnership is not a consent or waiver to or of any other breach or default in the
performance by that Person of the same or any other obligations of that Person with respect to the
Partnership. Failure on the part of a Person to complain of any act of any Person or to declare

21

 

any
Person in default with respect to the Partnership, irrespective of how long that failure continues,
does not constitute a waiver by that Person of its rights with respect to that default until the

only by a written instrument executed by all of the Partners.

ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE
THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER
JURISDICTION. If any provision of this Agreement or its application to any Person or circumstance
is held invalid or unenforceable to any extent, the remainder of this Agreement and the application
of that provision to other Persons or circumstances is not affected and that provision shall be
enforced to the greatest extent permitted by law.

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

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

     12.10 Indemnification. To the fullest extent permitted by law, each Partner shall indemnify
the Partnership and each other Partner and hold them harmless from and against all losses, costs,
liabilities, damages, and expenses (including, without limitation, costs of suit and attorney’s
fees) they may incur on account of any breach by that Partner of this Agreement.

     12.11 Counterparts. This Agreement maybe executed in any number of counterparts with the same

business must be conducted in that name or such other names that comply with applicable law as the
General Partner may select from time to time.

     2.03 Offices. The registered office of the Partnership in the State of Delaware shall be at

ARTICLE III: PARTNERS AND PARTNERSHIP INTERESTS

     3.01 Partners. The DEP Party was previously admitted to the Partnership as general partner of
the Partnership, and as of the date of this Agreement holds all of the General Partner Interests.
The EPD Party was previously admitted to the Partnership as a limited partner as of the date of
this Agreement, and as the date of this Agreement holds all of the Limited Partner Interests.

     3.02 No Dispositions of Partnership Interests. Except as set forth in Article 4 of the
Omnibus Agreement, the Partnership Interests may not be Disposed of, and any purported Disposition
of the Partnership Interests shall be null and void.

     3.03 Additional Partnership Interests. Additional Partnership Interests may be created and
issued to new or existing Partners only in compliance with the provisions in Article 5 of the
Omnibus Agreement. The Partnership shall be bound by the terms of such Omnibus Agreement.

ARTICLE IV: CAPITAL CONTRIBUTIONS

     4.01 Initial Contributions. The Partners have previously contributed (whether through actual
contributions or as a result of their acquisition of their Partnership Interests from predecessors)
to the Partnership those assets which are currently listed as assets of the Partnership on the
Partnership’s books and records.

     4.02 Subsequent Contributions.
Except as set forth in this Section 4.02 and in Section 4.03, no Partner shall be required
to make any Additional Capital Contributions on or after the date of this Agreement. In the event
the General Partner determines for any quarter there exists an operating cash flow deficit such
that available cash is insufficient to cover operating expenses, debt service and a reasonable
contingency reserve (but excluding for purposes of clarification cash needed for acquisitions or
Expansion Projects), the General Partner may require each of the Partners to make Additional
Capital Contributions pro rata in accordance with their respective Distribution Ratios in an amount
sufficient to cover such operating cash flow deficit.

     4.03 Expansion Project Additional Capital Contributions.

          (a) The General Partner may request additional capital contributions to fund Expansion
Projects (“Expansion Cash Calls”). Except as otherwise provided in this Section 4.03 or otherwise
agreed to by each of the Partners, any requested Capital Contributions for Expansion Cash Calls
attributable to an Expansion Project shall be made by the Partners in accordance with their
Percentage Interest. The costs of construction of, or acquisition of assets relating to, and other
expenditures for Expansion Projects funded exclusively out of Capital Contributions made by the
Partners (the “Expansion Costs”) and the related funding of Expansion Cash Calls shall be borne
solely by the Partners as set forth below in this Section 4.03, unless agreed to otherwise by all
of such Partners, in an amount equal to the product of (A) the aggregate amount of the Expansion
Costs multiplied by (B) a fraction, the numerator of

9

 

which is the Percentage Interest of
such participating Partner and the denominator of which is the aggregate Percentage Interest of all
of the participating Partners.

          (b) The General Partner shall provide written notice to the Partners of the date contributions
are due, which date shall be not less than 30 nor more than 90 Days following the date of such
notice, the aggregate amount of the Capital Contribution required and each Partner’s share thereof,
and setting forth in reasonable detail the proposed Expansion Project and Expansion Costs
associated therewith. Each Partner shall advise the General Partner in writing within 20 Days
whether it elects to make an Expansion Capital Contribution.

          (c) If the DEP Party elects to make an Expansion Capital Contribution with respect to an
Expansion Project within 20 Days after notice of such Expansion Cash Call, then (i) the EPD Party
may make additional Capital Contributions of cash in an amount up to the product of its Percentage
Interest and the amount of the applicable Expansion Cash Call and (ii) the DEP Party shall make
additional Capital Contributions of cash equal to the excess of the Expansion Cash Call over
amounts elected to be contributed by the EPD Party under clause (i) immediately preceding.

          (d) If the DEP Party elects not to make an Expansion Capital Contribution with respect to an
Expansion Project within 20 Days after notice of such Expansion Cash Call, then the EPD Party may
make Expansion Capital Contributions of cash in an amount equal to 100% of such Expansion Cash
Call. Notwithstanding the foregoing, the DEP Party may subsequently elect to make an Expansion
Capital Contribution associated with any Expansion Project by paying to the EPD Party, within 90
Days following the applicable Initial
Commencement Date, an amount equal to the product of (i) the sum of (A) the amount of the
Expansion Cash Call, plus (B) the effective cost of capital to the EPD Party based on the weighted
average interest rate of the EPD Party incurred for borrowings during such period as determined by
its Board of Directors in its reasonable judgment, minus (C) any amounts, if any, distributed to
the EPD Party with respect to its additional Capital Contributions associated with such Expansion
Project pursuant to the limited liability company agreement of Enterprise Texas multiplied by the
Percentage Interest of the DEP Party, and (ii) the Percentage Interest of the DEP Party. If the
DEP Party makes a payment pursuant to this Section 4.03(d), then (1) the DEP Party shall be deemed
to make a cash Capital Contribution to the Partnership in an amount equal to such payment and (2)
the Partnership shall be deemed to make a cash distribution to the EPD Party in an amount equal to
such payment.

     4.04 Advances by Partners. If the Partnership does not have sufficient cash to pay its
obligations, the General Partner, or any Limited Partner(s) that may agree to do so with the
General Partner’s consent, may advance all or part of the needed funds to or on behalf of the
Partnership. Payment by the General Partner on account of liability as a matter of law for
Partnership obligations is deemed to be an advance under this Section 4.03. An advance described in
this Section 4.03 constitutes a loan from the Partner to the Partnership, bears interest at a rate
determined by the General Partner (and, if applicable, the Limited Partner making the advance) from
the date of the advance until the date of payment, and is not a Capital Contribution.

10

 

     4.05 Capital Accounts. A capital account shall be established and maintained for each
Partner. Each Partner’s capital account (a) shall be increased by (i) the amount of money
contributed by that Partner to the Partnership, (ii) the fair market value of property contributed
by that Partner to the Partnership (net of liabilities secured by the contributed property that the
Partnership is considered to assume or take subject to under section 752 of the Code), and (iii)
allocations to that Partner of Partnership income and gain (or items of income and gain), including
income and gain exempt from tax and income and gain described in Treas. Reg.
§ 1.704-1(b)(2)(iv)(g), but excluding income and gain described in Treas. Reg. § 1.704-1(b)(4)(i),
and (b) shall be decreased by (i) the amount of money distributed to that Partner by the
Partnership, (ii) the fair market value of property distributed to that Partner by the Partnership
(net of liabilities secured by the distributed property that the Partner is considered to assume or
take subject to under section 752 of the Code), (iii) allocations to that Partner of expenditures
of the Partnership described in section 705(a)(2)(B) of the Code, and (iv) allocations of
Partnership loss and deduction (or items of loss and deduction), including loss and deduction
described in Treas. Reg. § 1.704-1(b)(2)(iv)(g), but excluding items described in clause (b)(iii)
above and loss or deduction described in Treas. Reg. § 1.704-1(b)(4)(i) or § 1.704-1(b)(4)(iii).
The Partners’ capital accounts also shall be maintained and adjusted as permitted by the provisions
of Treas. Reg. § 1.704-1(b)(2)(iv)(f) and as required by the other provisions of Treas. Reg. §§
1.704-1(b)(2)(iv) and 1.704-1(b)(4), including adjustments to reflect the allocations to the
Partners of depreciation, depletion, amortization, and gain or loss as computed for book purposes
rather than the allocation of the corresponding items as computed for tax purposes, as required by
Treas. Reg. § 1.704-1(b)(2)(iv)(g). A Partner that has more than one Partnership Interest shall
have a single
capital account that reflects all its Partnership Interests, regardless of the class of
Partnership Interests owned by that Partner and regardless of the time or manner in which those
Partnership Interests were acquired.

ARTICLE V: ALLOCATIONS AND DISTRIBUTIONS

     5.01 Allocations.

          (a) General. After giving effect to the special allocations set forth in Section 5.01(b), for
purposes of maintaining the capital accounts and in determining the rights of the Partners among
themselves, all items of income, gain, loss and deduction of the Partnership shall be allocated and
charged to the Partners’ capital accounts in accordance with their respective Percentage Interests.

          (b) Special
Allocations. Notwithstanding any other provisions of this Section 5.01, the
following special allocations shall be made prior to making any allocations provided for in 5.01(a)
above:

     (i) Minimum Gain Chargeback. Notwithstanding any other provision hereof to the
contrary, if there is a net decrease in Minimum Gain (as generally defined under
Treas. Reg. § 1.704-1 or § 1.704-2) for a taxable year (or if there was a net
decrease in Minimum Gain for a prior taxable year and the Partnership did not have
sufficient amounts of income and gain during prior years to allocate among the
Partners under this subsection 5.01(b)(i), then items of income and gain shall be
allocated to each Partner in an amount equal to such Partner’s share

11

 

of the net
decrease in such Minimum Gain (as determined pursuant to Treas. Reg. §
1.704-2(g)(2)). It is the intent of the Partners that any allocation pursuant to
this subsection 5.01(b)(i) shall constitute a “minimum gain chargeback” under Treas.
Reg. § 1.704-2(f) and shall be interpreted consistently therewith.

     (ii) Partner Nonrecourse Debt Minimum Gain Chargeback. Notwithstanding any
other provision of this Article 5, except subsection 5.01(b)(i), if there is a net
decrease in Partner Nonrecourse Debt Minimum Gain (as generally defined under Treas.
Reg. § 1.704-1 or § 1.704-2), during any taxable year, any Partner who has a share
of the Partner Nonrecourse Debt Minimum Gain shall be allocated such amount of
income and gain for such year (and subsequent years, if necessary) determined in the
manner required by Treas. Reg. § 1.704-2(i)(4) as is necessary to meet the
requirements for a chargeback of Partner Nonrecourse Debt Minimum Gain.

     (iii) Priority Allocations. Items of Partnership gross income or gain for the
taxable period shall be allocated to the Partners until the cumulative amount of
such items allocated to each Partner pursuant to this Section 5.01(b)(iii) for the
current and all previous taxable years equals the cumulative amount of
distributions made to such Partner pursuant to Section 5.02(a) for the current
and all previous taxable years.

     (iv) Qualified Income Offset. Except as provided in subsection 5.01(b)(i) and
(ii) hereof, in the event any Partner unexpectedly receives any adjustments,
allocations or distributions described in Treas. Reg. Sections
1.704-1(b)(2)(i)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items
of Partnership income and gain shall be specifically allocated to such Partner in an
amount and manner sufficient to eliminate, to the extent required by the Allocation
Regulations, the deficit balance, if any, in its adjusted capital account created by
such adjustments, allocations or distributions as quickly as possible.

     (v) Gross Income Allocations. In the event any Partner has a deficit balance
in its adjusted capital account at the end of any Partnership taxable period, such
Partner shall be specially allocated items of Partnership gross income and gain in
the amount of such excess as quickly as possible; provided, that an allocation
pursuant to this subsection 5.01(b)(v) shall be made only if and to the extent that
such Partner would have a deficit balance in its adjusted capital account after all
other allocations provided in this Section 5.01 have been tentatively made as if
subsection 5.01(b)(v) were not in the Agreement.

     (vi) Partnership Nonrecourse Deductions. Partnership Nonrecourse Deductions
(as determined under Treas. Reg. Section 1.704-2(c)) for any fiscal year shall be
allocated among the Partners in proportion to their Partnership Interests.

     (vii) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions (as
defined under Treas. Reg. Section 1.704-2(i)(2)) shall be allocated

12

 

pursuant to
Treas. Reg. Section 1.704-2(i) to the Partner who bears the economic risk of loss
with respect to the partner nonrecourse debt to which it is attributable.

     (viii) Code Section 754 Adjustment. To the extent an adjustment to the
adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of
the Code is required, pursuant to the Allocation Regulations, 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 Partners in a manner
consistent with the manner in which their capital accounts are required to be
adjusted pursuant to the Allocation Regulations.

     (ix) Curative Allocation. The special allocations set forth in subsections
5.01(b)(i), (ii) and (iv)-(vii) (the “Regulatory Allocations”) are intended to
comply with the Allocation Regulations. Notwithstanding any other provisions of
this Section 5.01, the Regulatory Allocations shall be taken into account in
allocating items of income, gain, loss and deduction among the Partners such that,
to the extent possible, the net amount of allocations of such
items and the Regulatory Allocations to each Partner shall be equal to the net
amount that would have been allocated to each Partner if the Regulatory Allocations
had not occurred.

          (c) For federal income tax purposes, except as otherwise required by the Code, the Allocation
Regulations or the following sentence, each item of Partnership income, gain, loss, deduction and
credit shall be allocated among the Partners in the same manner as corresponding items are
allocated in Sections 5.01(a) and (b). Notwithstanding any provisions contained herein to the
contrary, solely for federal income tax purposes, items of income, gain, depreciation, gain or loss
with respect to property contributed or deemed contributed to the Partnership by a Partner shall be
allocated so as to take into account the variation between the Partnership’s tax basis in such
contributed property and its Carrying Value in the manner provided under Section 704(c) of the Code
and Treas. Reg. § 1.704-3(d) (i.e. the “remedial method”).

     5.02 Distributions.

          (a) At least quarterly prior to commencement of winding up under Section 11.02, the General
Partner shall determine in its reasonable judgment to what extent (if any) the Partnership’s cash
on hand, exceeds its current and anticipated needs, including, without limitation, for operating
expenses, debt service, acquisitions, and a reasonable contingency reserve. If such an excess
exists, the General Partner shall cause the Partnership to distribute to the Partners, in
accordance with their respective Distribution Ratios, an amount in cash equal to that excess on or
before the date 30 days following the end of each such fiscal quarter.

          (b) From time to time the General Partner also may cause property of the Partnership other
than cash to be distributed to the Partners, which distribution must be made in accordance with
Section 5.02(a) and may be made subject to existing liabilities and obligations.

13

 

Immediately prior
to such a distribution, the capital accounts of the Partners shall be adjusted as provided in
Treas. Reg. § 1.704-1(b)(2)(iv)(f).

ARTICLE
VI: MANAGEMENT AND OPERATION

     6.01 Management of Partnership Affairs.

          (a) Except for situations in which the approval of the Limited Partners is expressly required

the Partnership; or

     (iv) any repurchase or redemption of Partnership Interests or any equity
interests of any subsidiary of the Partnership.

          (b) A Limited Partner may not act for or on behalf of the Partnership, do any act that would

          (c) Any Person dealing with the Partnership, other than a Limited Partner, may rely on the
authority of the General Partner in taking any action in the name of the Partnership without
inquiry into the provisions of this Agreement or compliance with it, regardless of whether that
action actually is taken in accordance with the provisions of this Agreement.

     6.02 Compensation. The General Partner is not entitled to compensation for its services as
General Partner, but it is entitled to be reimbursed for out-of-pocket costs and expenses incurred

ONLY IN THE CASE OF BAD FAITH, GROSS NEGLIGENCE, OR BREACH OF THE PROVISIONS OF THIS AGREEMENT, BUT
NOT OTHERWISE. The General Partner shall devote such time and effort to the Partnership business
and operations as is necessary to promote fully the interests of the Partnership; however, the
General Partner need not devote full time to Partnership business.

          (b) Subject to the other provisions of this Agreement, the General Partner and each Limited
Partner at any time and from time to time may engage in and possess interests in other business
ventures of any and every type and description, independently or with others, including ones in
competition with the Partnership, with no obligation to offer to the Partnership or any other
Partner the right to participate in those activities.

          (c) The Partnership may transact business with any Partner or affiliate of a Partner, provided
the terms of the transactions are no less favorable than those the Partnership could obtain from
unrelated third parties.

     6.04 Indemnification. To the fullest extent permitted by applicable law, on request by the
Person indemnified the Partnership shall indemnify the General Partner, its affiliates, and their
respective officers, directors, partners, employees, and agents and hold them harmless from and

INCLUDING THE PERSON INDEMNIFIED’S SOLE, PARTIAL, OR CONCURRENT NEGLIGENCE, and on request by the

ARTICLE
VII: RIGHTS OF LIMITED PARTNERS

     7.01 Information.

          (a) In addition to the other rights set forth in this Agreement, each Limited Partner is
entitled to all information to which that Limited Partner is entitled to have access under the Act
under the circumstances and subject to the conditions therein stated; provided, however, that the
General Partner may determine, due to contractual obligations, business concerns, or other
considerations, that certain information regarding the business, affairs, properties, and
financial condition of the Partnership should be kept confidential and not provided to some or
all Limited Partners. The Partners agree that the restrictions in the immediately preceding
sentence are just and reasonable.

          (b) The Partners acknowledge that, from time to time, they may receive information from or
regarding the Partnership in the nature of trade secrets or that otherwise is confidential, the
release of which may be damaging to the Partnership or Persons with which it does business. Each
Partner shall hold in strict confidence and not use (except for matters involving the Partnership)

if that information is provided in writing, that is so marked) and may not disclose it to any
Person other than another Partner, except for disclosures (a) compelled by law (but the Partner
must notify the General Partner promptly of any request for that information, before disclosing it
if practicable), (b) to advisers or representatives of the Partner, but only if the recipients have
agreed to be bound by the provisions of this Section 7.01(b), or (c) of information that Partner
also has received from a source independent of the Partnership that the Partner reasonably believes

sole discretion, without regard to the interests of the Partnership or any other Partner.

          (b) In any request for consent or approval from another Partner, the General Partner may
specify a response period, ending no earlier than the fifth and no later than the 15th Business Day
following the date on which the Partner whose consent or approval is sought receives the request as

shall be deemed to have consented to or approved the action set forth in the request.

16

General Partner shall call, and at any time it may call, a meeting of the Partners to transact

the Partners.

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.

     8.03 Tax Matters Partner. The General Partner shall be the “tax matters partner” of the
Partnership pursuant to section 6231(a)(7) of the Code. The General Partner shall take such action
as may be necessary to cause each Limited Partner to become a “notice partner” within the meaning

significant matters that may come to its attention in its capacity as tax matters partner by giving
notice on or before the fifth Business Day after becoming aware of the matter and, within that
time, shall forward to each Limited Partner copies of all significant written communications it may
receive in that capacity.

ARTICLE IX: BOOKS, RECORDS, REPORTS, AND BANK ACCOUNTS

     9.01 Maintenance of Books. The books of account for the Partnership shall be maintained on a
accrual basis in accordance with the terms of this Agreement, except that the capital accounts of
the Partners shall be maintained in accordance with Section 4.04. The accounting year of the
Partnership shall end on December 31 of each year.

     9.02 Reports. If requested by any Partner in writing, on or before the 120th day following
the end of each fiscal year during the term of the Partnership, the General Partner shall cause
each Limited Partner to be furnished with a balance sheet, an income statement, and a statement of
changes in Partners’ capital of the Partnership for, or as of the end of, that year. These
financial statements must be prepared in accordance with accounting principles generally employed
for cash basis records consistently applied (except as noted in the statements). The General
Partner also may cause to be prepared or delivered such other reports as it may deem appropriate.
The Partnership shall bear the costs of all these reports.

     9.03 Accounts. The General Partner shall establish and maintain one or more separate bank and
investment accounts and arrangements for Partnership funds in the Partnership name with financial
institutions and firms that the General Partner determines. The General Partner may not commingle
the Partnership’s funds with the funds of any Partner; however, Partnership funds may be invested
in a manner the same as or similar to the General Partner’s investment of its own funds or
investments by its affiliates.

ARTICLE X: WITHDRAWAL, BANKRUPTCY, ETC. OF GENERAL PARTNER

     10.01 Withdrawal, Bankruptcy, Removal Etc. of General Partner.

          (a) Except as provided in Section 10.01(d), the General Partner agrees that it will not
withdraw from the Partnership as a general partner. If the General Partner withdraws from the
Partnership in violation of this covenant, the withdrawal is effective on the 90th day following
notice of the withdrawal to all Limited Partners, or such later date as the notice may specify. On
a withdrawal in violation of this Section 10.01(a), the Partnership’s remedies shall be limited to
the recovery of monetary damages arising from such violation, it being understood that neither the
Partnership nor any Limited Partner shall have the right, through specific performance or
otherwise, to prevent the General Partner from withdrawing in violation of this Agreement.

          (b) The General Partner shall notify each Limited Partner that an event of the type described
in Section 17-402(a)(4), (5), or (7)-(12) of the Act has occurred with respect to it on or before
the fifth Business Day after that occurrence.

          (c) Following any notice that the General Partner is withdrawing (other than pursuant to
Section 10.01(d)), a Required Interest by written consent may select a new General Partner. The
Person selected shall be admitted to the Partnership as the General Partner effective immediately
prior to the existing General Partner’s ceasing to be the General Partner with a Percentage
Interest that the Limited Partners making the
selection specify, but only if the new General
Partner has made a Capital Contribution in an amount the Limited Partners making the

18

 

selection
specify and has executed and delivered to the Partnership a document including the new General
Partner’s notice address and its agreement to be bound by this Agreement. Notwithstanding the
foregoing provisions of this Section 10.01(c), for the right to select a new General Partner to be
exercised, the Partnership must receive a favorable opinion of the Partnership’s legal counsel or
of other legal counsel acceptable to the Limited Partners making the selection to the effect that
the selection and admission (if any) will not result in (i) the loss of limited liability of any
Limited Partner or (ii) the Partnership’s being treated as an association taxable as a corporation
for federal income tax purposes.

          (d) The General Partner may be removed by a written consent of Partners holding a majority of
the Distribution Ratios. The General Partner may not be removed if such removal would result in
the termination or dissolution of the Partnership under applicable law. The new General Partner
shall not be required to make any Capital Contributions to the Partnership, shall not have a
Percentage Interest or be entitled to any distributions from the Partnership pursuant to Section
5.02. The new General Partner shall execute and deliver to the Partnership a document including the
new General Partner’s notice address and its agreement to be bound by this Agreement. The General
Partner shall not be removed unless and until a new, successor General Partner has been identified
and such successor General Partner has been admitted to the Partnership. The Partners agree to
execute any amendments to this Agreement and take any other actions required to effect the changes
specified in this Section 10.01(d).

     10.02 Conversion of Interest. Simultaneously with the General Partner’s ceasing to be General
Partner following the admission of a new General Partner pursuant to Section 10.01(c) or (d), the
former General Partner’s Partnership Interest as the General Partner automatically is converted
into that of a Limited Partner having a Percentage Interest equal to the Percentage Interest of the
former General Partner as the General Partner immediately prior to its ceasing to be the General
Partner, and the General Partner automatically is admitted to the Partnership as a Limited Partner.

ARTICLE XI: DISSOLUTION, LIQUIDATION, AND TERMINATION

     11.01 Dissolution. The Partnership shall dissolve and its business and affairs shall be wound
up on the first to occur of the following:

          (a) the written consent of the General Partner and a Required Interest;

          (b) the date set forth in Section 2.06;

          (c) the General Partner’s ceasing to be the General Partner as described in Section 10.01(a)
or (d), unless a new General Partner is selected and admitted as provided in Section 10.01(c) or
(d);

          (d) the entry of a decree of judicial dissolution under Section 17-802 of the Act;

          (e) any other event causing dissolution as described in Section 17-801 of the Act (other than
an event described in Section 17-402(a)(4) or (10) of the Act, except as provided in Section
11.01(c));

19

 

provided, however, that if dissolution occurs due to an “event of withdrawal” (as defined in the
Act) with respect to the General Partner and a new General Partner is being admitted pursuant to
Section 10.01(c), the Partnership automatically shall be reconstituted and the new General Partner
shall, and hereby agrees to, carry on the business of the Partnership.

     11.02 Liquidation and Termination. On dissolution of the Partnership, unless it is
reconstituted and continued as provided in Section 11.01, the General Partner shall act as
liquidator or may appoint one or more other Persons as liquidator; provided, however, that if the
Partnership dissolves on account of an event of the type described in Section 17-402(a)(4)-(12) of
the Act with respect to the General Partner, the liquidator shall be one or more Persons selected
in writing by a Required Interest. The liquidator shall proceed diligently to wind up the affairs
of the Partnership and make final distributions as provided in this Agreement. The costs of
liquidation shall be borne as a Partnership expense. Until final distribution, the liquidator shall
continue to operate the Partnership properties with all of the power and authority of the General
Partner. The steps to be accomplished by the liquidator are as follows:

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

          (b) the liquidator shall pay from Partnership funds all of the debts and liabilities of the
Partnership (including, without limitation, all expenses incurred in liquidation and any advances
described in Section 4.03) or otherwise make adequate provision for them (including, without
limitation, the establishment of a cash escrow fund for contingent liabilities in such amount and
for such term as the liquidator may reasonably determine); and

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

     (i) the liquidator may sell any or all Partnership property, including to
Partners, and any resulting gain or loss from each sale shall be computed and
allocated to the capital accounts of the Partners;

     (ii) with respect to all Partnership property that has not been sold, the fair
market value of that property shall be determined and the capital accounts of the
Partners shall be adjusted to reflect the manner in which the unrealized income,
gain, loss, and deduction inherent in property that has not been reflected in the
capital accounts previously would be allocated among the Partners if there were a
taxable disposition of that property for the fair market value of that property on
the date of distribution; and

     (iii) Partnership property shall be distributed among the Partners in
accordance with the positive capital account balances of the Partners, as determined
after taking into account all capital account adjustments for the taxable year of
the Partnership during which the liquidation of the Partnership

20

 

occurs (other than
those made by reason of this clause (iii)); and those distributions shall be made by
the end of the taxable year of the Partnership during which the liquidation of the
Partnership occurs (or, if later, 90 days after the date of the liquidation).

All distributions in kind to the Partners shall be made subject to the liability of each
distributee for its allocable share of costs, expenses, and liabilities previously incurred or for
which the Partnership has committed prior to the date of termination and those costs, expenses, and
liabilities shall be allocated to the distributee under this Section 11.02. The distribution of
cash and/or property to a Partner in accordance with the provisions of this Section 11.02
constitutes a complete return to the Partner of its Capital Contributions and a complete
distribution to the Partner of its Partnership Interest and all the Partnership’s property and
constitutes a compromise to which all Partners have consented within the meaning of Section
17-502(b)(1) of the Act. To the extent that a Partner returns funds to the Partnership, it has no
claim against any other Partner for those funds.

     11.03 Termination. On completion of the distribution of Partnership assets as provided in
this Agreement, the Partnership is terminated, and the General Partner (or such other Person or
Persons as the Act may require or permit) shall cause the cancellation of the Certificate and any
filings made as provided in Section 2.05 and shall take such other actions as may be necessary to
terminate the Partnership.

ARTICLE XII: GENERAL PROVISIONS

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

     12.02 Notices. All notices, requests, or consents provided for or permitted to be given under
this Agreement must be in writing and must be given either by depositing that writing in the United
States mail, addressed to the recipient, postage paid, and registered or certified with return
receipt requested or by delivering that writing to the recipient in person, by courier, or by
facsimile transmission. A notice, request, or consent given under this Agreement is effective on
receipt at the address of the Person to receive it. All notices, requests, and consents to be sent
to a Partner must be sent to or made at the addresses given for that Partner on Exhibit A or in the
instrument described in Sections 10.01(c) and (d), or such other address as that Partner may
specify by notice to the other Partners. Any notice, request, or consent to the Partnership must be
given to the General Partner.

     12.03 Entire Agreement; Supersedure. This Agreement constitutes the entire agreement of the
Partners and their affiliates relating to the Partnership and supersedes all prior contracts or
agreements with respect to the Partnership, whether oral or written.

     12.04 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any
breach or default by any Person in the performance by that Person of its obligations with respect
to the Partnership is not a consent or waiver to or of any other breach or default in the
performance by that Person of the same or any other obligations of that Person with respect to the
Partnership. Failure on the part of a Person to complain of any act of any Person or to declare

21

 

any
Person in default with respect to the Partnership, irrespective of how long that failure continues,
does not constitute a waiver by that Person of its rights with respect to that default until the
applicable statute of-limitations period has run.

     12.05 Amendment or Modification. This Agreement may be amended or modified from time to time
only by a written instrument executed by all of the Partners.

     12.06 Binding Effect. Subject to the restrictions on Dispositions set forth in this
Agreement, this Agreement is binding on and inures to the benefit of the Partners and their
respective heirs, legal representatives and successors.

     12.07 Governing Law; Severability. THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE
THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER
JURISDICTION. If any provision of this Agreement or its application to any Person or circumstance
is held invalid or unenforceable to any extent, the remainder of this Agreement and the application
of that provision to other Persons or circumstances is not affected and that provision shall be
enforced to the greatest extent permitted by law.

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

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

     12.10 Indemnification. To the fullest extent permitted by law, each Partner shall indemnify
the Partnership and each other Partner and hold them harmless from and against all losses, costs,
liabilities, damages, and expenses (including, without limitation, costs of suit and attorney’s
fees) they may incur on account of any breach by that Partner of this Agreement.

     12.11 Counterparts. This Agreement maybe executed in any number of counterparts with the same
effect as if all signing parties had signed the same document. All counterparts shall be construed
together and constitute the same instrument.
