                                       -6-

other decisions relating to such allocations shall be made by the General
Partner in any manner that reasonably reflects the purpose and intention of this
Agreement.

            (d)   Discretion; Effect. Any election or other decision relating to
allocations pursuant to this Section 5.2 shall be made by the General Partner in
any manner that reasonably reflects the purposes and intention of this
Agreement. Allocations pursuant to this Section 5.2 are for purposes of federal,
state and local taxes only and shall not affect or in any way be taken into
account in computing any Partner's Capital Account balance or share of Net
Profits, Net Losses or distributions pursuant to any provision of the Agreement.

                            TRANSFERS AND WITHDRAWALS

            8.1.  Transfer. Except as provided in this Article 8, no Partnership
Interest shall be Transferred, in whole or in part. Any attempted Transfer in
contravention of this Article 8 shall be void ab initio; provided, however, that
this Article 8 shall be subject to and construed in a manner consistent with the
General Partner's power to cause the Partnership to participate in a merger,
consolidation, entity conversion, share or interest exchange as permitted by the
Act, and no exercise of the General Partner's powers under Section 7.1(k) shall
be prohibited by this Article 8.

            8.2.  Permitted Transfers. The Limited Partner may freely Transfer
its Partnership Interest without the consent of any Partner. The General Partner
may freely Transfer its Partnership Interest, in whole, upon at least ten (10)
days prior written notice to each Partner, but without the consent or approval
of any Partner. Any successor general partner of the Partnership permitted by
this Section 8.2 shall to the fullest extent permitted by law be deemed admitted
as a general partner of the Partnership immediately prior to the withdrawal of
the General Partner as a general partner of the Partnership. Any successor
General Partner permitted by this Section 8.2 is hereby authorized to, and shall
continue the business of, the Partnership without dissolution.

                                      -10-


            8.3.  Withdrawal. No Partner may withdraw from the Partnership,
other than as a result of a permitted Transfer.

            8.4.  Transferees to be Bound by this Agreement. Notwithstanding any
other provision of this Agreement, no Partnership Interest may be Transferred,
and no Transfer shall be effective, unless and until the proposed Transferee
shall in a writing addressed to each other Partner agree to be bound by this
Agreement. Each Transferee shall be deemed admitted as a General Partner or a
Limited Partner, as the case may be, at such time such Person executes the
writing described in the preceding sentence.

            8.5.  Substitution. No Partner shall have the right, power, or
authority to substitute for itself, as a partner in the Partnership, any Person
who is not a Partner of the Partnership, unless such Partner has transferred its
Partnership Interest in accordance with the terms of this Article 8.

                                   ARTICLE IX.

                                   DISSOLUTION

            9.1.  Dissolution Events.

            (a)   Except as set forth in this Article 9, no Partner shall have
the right to dissolve the Partnership.

            (b)   The Partnership shall dissolve, and its affairs shall be wound
up, upon the first to occur of (i) the expiration of its stated term as provided
in Section 2.9; (ii) the sale or disposition of all or substantially all of the
assets of the Partnership in accordance with this Agreement; or (iii) the
written consent of all Partners.

            9.2.  Winding Up.

            (a)   Upon the occurrence of an event of dissolution described in
Section 9.1(b), the Partnership shall continue solely for the purposes of
winding up its affairs in an orderly manner, liquidating its assets, and
satisfying the claims of its creditors and Partners. No Partner shall take any
action that is inconsistent with, or not necessary to or appropriate for, the
winding up of the Partnership's business and affairs. The General Partner or any
Person designated by the General Partner (such Person being deemed to be a
"liquidating trustee" within the meaning of the Act is hereinafter referred to
as the "LIQUIDATOR") shall be responsible for overseeing the winding up and
dissolution of the Partnership and shall take full account of the Partnership's
liabilities and property and the Partnership property shall be liquidated as
promptly as is consistent with obtaining the fair value thereof, and the
proceeds therefrom shall be applied and distributed in the following order: (i)
first, to any creditors of the Partnership, in satisfaction of liabilities of
the Partnership (whether by payment or the making of reasonable provisions for
payment thereof); and (ii) second, to the Partners in proportion to their
respective positive Capital Account balances.

            For purposes of this Section 9.2, the Capital Account balances of
the Partners shall be determined after making Capital Account adjustments under
Article 5 to account for the

                                      -11-


results of Partnership operations, and for all sales and dispositions of all or
any part of the Partnership's assets, through the time of any liquidating
distribution. Additionally, for purposes of adjusting Capital Accounts and
making liquidating distributions, Net Profits and Net Losses shall be determined
and the Capital Accounts of the Partners shall be adjusted as if any unsold
assets that are distributed to the Partners had been sold for their fair market
values, and the distribution of such assets shall be treated as a distribution
of cash equal to the fair market value of such assets.

            (b)   Notwithstanding the provisions of Section 9.2(a) which require
liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership
the Liquidator determines that an immediate sale of part or all of the
Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership and/or distribute to the Partners in lieu of
cash, as tenants in common and in accordance with the provisions of Section
9.2(a), undivided interests in such Partnership assets as the Liquidator deems
not suitable for liquidation. Any such distributions in kind shall be made only
if, in the good faith judgment of the Liquidator, such distributions in kind are
in the best interest of the Partners, and shall be subject to such conditions
relating to the disposition and management of such properties as the Liquidator
deems reasonable and equitable and to any agreements governing the operation of
such properties at such time. The Liquidator shall determine the fair market
value of any property distributed in kind using such reasonable method of
valuation as it may adopt.

            (c)   In the discretion of the Liquidator, a pro rata portion of the
distributions that would otherwise be made to the Partners pursuant to this
Article IX may be (i) distributed to a trust established for the benefit of the
Partners for the purposes of liquidating Partnership assets, collecting amounts
owed to the Partnership, and paying any contingent, conditional or unmatured
liabilities or obligations of the Partnership or of the General Partner arising
out of or in connection with the Partnership and the assets of any such trust
shall be distributed to the Partners from time to time, in the reasonable
discretion of the Liquidator, in the same manner and priority as such assets
would have been distributed by the Partnership to the Partners pursuant to
Section 9.2(a) of this Agreement, or (ii) withheld or escrowed to provide a
reasonable reserve for Partnership liabilities (contingent or otherwise) and to
reflect the unrealized portion of any installment obligations owed to the
Partnership, provided that such withheld or escrowed amounts shall be
distributed to the Partners in the manner and order of priority set forth in
Section 9.2(a) as soon as practicable.

            9.3.  Negative Capital Accounts. No Partner shall be liable to the
Partnership or to any other Partner for any negative balance outstanding in such
Partner's Capital Account, whether such negative Capital Account results from
the allocation of Net Losses or other items of deduction and loss to such
Partner or from distributions to such Partner.

            9.4.  Rights to Return of Capital. Except as otherwise provided in
this Agreement, the Partners shall look solely to the assets of the Partnership
for the return of their Capital Contributions and shall have no right or power
to demand or receive property other than cash from the Partnership.

                                      -12-


            9.5.  Termination of Partnership and Cancellation of Certificate of
Limited Partnership. Upon the completion of the liquidation of the Partnership
cash and property as provided in Section 9.2, the Partnership shall be
terminated, a certificate of cancellation shall be filed, and all qualifications
of the Partnership as a foreign Limited Partnership in jurisdictions other than
the State of Texas shall be canceled and such other actions as may be necessary
to terminate the Partnership shall be taken. The General Partner shall not cause
or permit any such certificate of cancellation to be filed or any other such
action to be taken except following the dissolution, and upon completion of the
winding up and liquidation, of the Partnership pursuant to this Article 9.

            9.6.  Reasonable Time for Winding-Up. A reasonable time shall be
allowed for the orderly winding-up of the business and affairs of the
Partnership and the liquidation of its assets pursuant to Section 9.2, in order
to minimize any losses otherwise attendant upon such winding-up, and the
provisions of this Agreement shall remain in effect among the Partners during
the period of winding-up and liquidation.

            9.7.  Waiver of Partition. Each Partner hereby waives any right to
partition of the Partnership property.

                                    ARTICLE X

                   LIABILITY, EXCULPATION AND INDEMNIFICATION

            10.1. Liability.

            (a)   Except as otherwise provided by the Texas Act, the debts,
obligations and liabilities of the Partnership, whether arising in contract,
tort or otherwise, shall be solely the debts, obligations and liabilities of the
Partnership, and no Covered Person shall be obligated personally for any such
debt, obligation or liability of the Partnership solely by reason of being a
Covered Person.

            (b)   Except as otherwise expressly required by law, no Partner, in
its capacity as Partner, shall have any liability in excess of (i) the amount of
its Capital Commitment, (ii) its share of any assets and undistributed profits
of the Partnership, (iii) its obligation to make other payments expressly
provided for in this Agreement, and (iv) the amount of any distributions
wrongfully distributed to it.

            10.2. Exculpation.

            (a)   NO COVERED PERSON SHALL BE LIABLE TO THE PARTNERSHIP OR ANY
OTHER COVERED PERSON FOR ANY LOSS, DAMAGE OR CLAIM INCURRED BY REASON OF ANY ACT
OR OMISSION PERFORMED OR OMITTED BY SUCH COVERED PERSON IN GOOD FAITH ON BEHALF
OF THE PARTNERSHIP AND IN A MANNER REASONABLY BELIEVED TO BE WITHIN THE SCOPE OF
AUTHORITY CONFERRED ON SUCH COVERED PERSON BY THIS AGREEMENT, UNLESS SUCH LOSS
OR LIABILITY ARISES FROM THE COVERED PERSON'S INTENTIONAL MISCONDUCT, GROSS
NEGLIGENCE, VIOLATION OF APPLICABLE LAW, MATERIAL BREACH OF THIS AGREEMENT OR
FRAUD.

                                      -13-


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

            10.3. Duties and Liabilities of Covered Persons.

            (a)   To the extent that, at law or in equity, a Covered Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Partnership or to any other Covered Person, a Covered Person acting under this
Agreement shall not be liable to the Partnership or to any other Covered Person
for its good faith reliance on the provisions of this Agreement. The provisions
of this Agreement, to the extent that they restrict the duties and liabilities
of a Covered Person otherwise existing at law or in equity, are agreed by the
parties hereto to replace such other duties and liabilities of such Covered
Person.

            (b)   Unless otherwise expressly provided herein, (a) whenever a
conflict of interest exists or arises between Covered Persons, or (b) whenever
this Agreement or any other agreement contemplated herein or therein provides
that a Covered Person shall act in a manner that is, or provides terms that are,
fair and reasonable to the Partnership or any Partner, the Covered Person shall
resolve such conflict of interest, taking such action or providing such terms,
considering in each case the relative interest of each party (including its own
interest) to such conflict, agreement, transaction or situation and the benefits
and burdens relating to such interests, any customary or accepted industry
practices, and any applicable generally accepted accounting practices or
principles. In the absence of bad faith by the Covered Person, the resolution,
action or term so made, taken or provided by the Covered Person shall not
constitute a breach of this Agreement or any other agreement contemplated herein
or of any duty or obligation of the Covered Person at law or in equity or
otherwise.

            (c)   Whenever in this Agreement a Covered Person is permitted or
required to make a decision (i) in its "discretion" or under a grant of similar
authority or latitude, the Covered Person shall be entitled to consider only
such interests and factors as it desires, including its own interests, and shall
have no duty or obligation to give any consideration to any interest of or
factors affecting the Partnership or any other Person, or (ii) in its "good
faith" or under another express standard, the Covered Person shall act under
such express standard and shall not be subject to any other or different
standard imposed by this Agreement or other applicable law.

            10.4. Indemnification.

            (a)   To the fullest extent permitted by law, the Partnership shall
indemnify and hold harmless each Covered Person from and against any and all
losses, claims, damages, liabilities, judgments, penalties (including excise and
similar taxes), fines, settlements and reasonable expenses (including court
costs and attorney's fees), joint or several, actually incurred

                                      -14-


by such Covered Person in connection with any threatened, pending or completed
claim, demand, action, suit or proceeding, whether civil, criminal,
administrative, arbitrative or investigative, any appeal in such a claim,
demand, action, suit or proceeding and any inquiry or investigation that could
lead to such a claim, demand, action, suit or proceeding (any such claim,
demand, action, suit, proceeding, appeal, inquiry or investigation being
hereinafter referred to as a "PROCEEDING"), in which such Covered Person was, is
or is threatened to be made a named defendant or respondent because such Covered
Person has or had any status specified in clause (i) or (ii) above, REGARDLESS
OF WHETHER ANY OF SAID LOSSES, CLAIMS, DAMAGES, LIABILITIES, JUDGMENTS,
PENALTIES, FINES, SETTLEMENTS OR EXPENSES RESULTED FROM THE NEGLIGENCE OR OTHER
FAULT OF SUCH COVERED PERSON. Notwithstanding the foregoing, no Covered Person
shall be indemnified and held harmless unless (x) a determination is made in
accordance with the procedures prescribed in Section 11.06 of the Act that such
Covered Person (1) acted in good faith, (2) reasonably believed that its conduct
was in the best interests of the Partnership (in the case of conduct by a person
in its official capacity) or at least not opposed to the best interests of the
Partnership (in all other cases) and (3) in the case of a criminal Proceeding,
had no cause to believe that its conduct was unlawful and (y) such Covered
Person's conduct did not constitute intentional misconduct, gross negligence, a
violation of applicable law, a material breach of this agreement or fraud. The
termination of any Proceeding by judgment, order, settlement, conviction or on a
plea of nolo contendere or its equivalent shall not alone determine that an
Covered Person did not meet the requirements set forth in the preceding
sentence.

            (b)   To the fullest extent permitted by law and without limiting
any right granted to an Covered Person under paragraph (a) above, the
Partnership shall indemnify and hold harmless each Covered Person from and
against any and all reasonable expenses (including court costs and attorney's
fees) incurred by such Covered Person in connection with a Proceeding in which
the Covered Person was a named defendant or respondent because such Covered
Person has or had any status specified in clause (i) or (ii) of the first
sentence of paragraph (a) above, if such Covered Person has been wholly
successful, on the merits or otherwise, in the defense of such Proceeding.

            (c)   To the fullest extent permitted by law, the Partnership shall
pay or reimburse, in advance of the final disposition of a Proceeding,
reasonable expenses (including court costs and attorney's fees) incurred by an
Covered Person who was, is or is threatened to be made a named defendant or
respondent in a Proceeding because such Covered Person has or had any status
specified in clause (i) or (ii) of the first sentence of paragraph (a) above;
provided, however, that prior to making any payment or reimbursement under this
paragraph (c), the Partnership shall receive (i) a written affirmation by such
Covered Person of such Covered Person's good faith belief that it has met the
standard of conduct necessary for indemnification under paragraph (a) above and
the Texas Act and (ii) a written undertaking by or on behalf of such Covered
Person to repay the amount paid or reimbursed if it is ultimately determined
that such Covered Person has not met such standard.

            (d)   The indemnification and advancement of expenses provided for
in this Section 10.4 shall be in addition to any other rights to which an
Covered Person may be entitled pursuant to any contract or agreement or any
action or approval of the Partners or as a matter of law, whether with respect
to an action of an Covered Person in any of its capacities specified in

                                      -15-


clause (i) or (ii) of the first sentence of paragraph (a) above or in any other
capacity, and shall continue as to an Covered Person who has ceased to serve in
such capacity and shall inure to the benefit of the heirs, successors, assigns
and administrators of an Covered Person. The General Partners and the
Partnership may enter into indemnity contracts with Covered Persons and adopt
written procedures pursuant to which arrangements are made for the advancement
of expenses and the funding of obligations under Section 10.4(c) and containing
such other procedures regarding indemnification as are appropriate.

            10.5. Insurance. The Partnership may purchase and maintain
insurance, to the extent and in such amounts as the General Partner shall, in
its discretion, deem reasonable, on behalf of Covered Persons and such other
Persons as the General Partner shall determine, against any liability that may
be asserted against or expenses that may be incurred by any such Person in
connection with the activities of the Partnership or such indemnities,
regardless of whether the Partnership would have the power to indemnify such
Person against such liability under the provisions of this Agreement. The
General Partner and the Partnership may enter into indemnity contracts with
Covered Persons and adopt written procedures pursuant to which arrangements are
made for the advancement of expenses and the funding of obligations under
Section 10.4 and containing such other procedures regarding indemnification as
are appropriate.

                                  ARTICLE XI.

                                 MISCELLANEOUS

            11.1. Amendments. This Agreement shall not be amended, modified,
waived or terminated without the prior written consent of each Partner.

            11.2. Complete Agreement. This Agreement constitutes the complete
and exclusive statement of the agreement between the Partners and replaces and
supersedes any oral or written agreements by and among the Partners or any of
them.

            11.3. Governing Law. This Agreement and the rights of the parties
hereunder shall be governed by, interpreted and enforced in accordance with, the
internal laws (exclusive of the choice of law provisions thereof or conflicts of
law rules thereof) of the State of Texas as to all matters, including, but not
limited to, matters of validity, construction, effect, performance and remedies.

            11.4. Binding Effect. Subject to the provisions of this Agreement
relating to transferability, this Agreement shall be binding upon the parties
signatory hereto, and their respective successors and Transferees, and inure to
the benefit of such parties and their respective successors and permitted
Transferees. All representations, agreements and covenants made by or applicable
to any Partner hereunder are made for the direct benefit of each other Partner
hereunder and its successors and permitted Transferees.

            11.5. Interpretation. Common nouns and pronouns shall be deemed to
refer to the masculine, feminine, neuter, singular and plural, as the identity
of the Person may in the context require. All headings, titles or captions
herein are inserted only for convenience and ease of reference and are not to be
considered in the construction or interpretation of any provision of

                                      -16-


this Agreement. Numbered or lettered articles, sections and subsections herein
contained refer to articles, sections and subsections of this Agreement unless
otherwise expressly stated. Words such as "herein," "hereinafter," "hereof,"
"hereto," "hereby" and "hereunder," when used with reference to this Agreement,
refer to this Agreement as a whole, unless the context otherwise requires. If
any provision of this Agreement or the application thereof to any Person or
circumstances is or becomes invalid or unenforceable to any extent, the
remainder of this Agreement and the application of such provisions to other
Persons or circumstances shall not be affected thereby and shall be enforced to
the greatest extent permitted by law.

            11.6. Reliance on Authority. In no event shall any Person dealing
with the General Partner be obligated to ascertain that the terms of this
Agreement have been complied with, or be obligated to inquire into the necessity
or expediency of any act or action of the General Partner. Every contract,
agreement, deed, mortgage, promissory note, or other instrument or document
executed by the General Partner with respect to the Partnership shall be
conclusive evidence in favor of any and every Person relying thereon or claiming
thereunder that (a) at the time of the execution and/or delivery thereof, this
Agreement was in full force and effect, (b) such instrument or document was duly
executed in accordance with the terms and provisions of this Agreement and is
binding upon the Partnership and all of the Partners thereof, and (c) the
General Partner was duly authorized and empowered to execute and deliver any and
every such instrument or document for and on behalf of the Partnership.

            11.7. No Third Party Beneficiary. This Agreement is made solely and
specifically among and for the benefit of the parties hereto, and their
respective successors and permitted Transferees subject to the express
provisions hereof relating to successors and permitted Transferees, and no other
Person shall have any rights, interest or claims hereunder or be entitled to any
benefits under or on account of this Agreement as a third party beneficiary or
otherwise. No third party, including any creditor of the Partnership shall have
any right to enforce any contribution of capital, loan, or other advance of
funds by any Partner.

            11.8. Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by

have been duly given or made (i) when delivered by hand, (ii) five (5) days
after being deposited in the mail, certified mail and postage prepaid, (iii) one
(1) day following timely delivery to a nationally recognized overnight courier
service, or (iv) in the case of facsimile notice, when sent and electronically
confirmed, addressed as provided in Exhibit A, or to such other address as may

            11.9. Waiver. No failure by any party to insist upon strict
performance of any covenant, duty, agreement or condition of this Agreement or
to exercise any right or remedy resulting from a breach thereof shall constitute
a waiver of any such breach or any other covenant, duty, agreement or condition
or any right or remedy.

            11.10. Limited Recourse. To the fullest extent permitted by law, in
no circumstances shall a shareholder, general or limited partner, director,
officer, employee or agent of a Partner or a partner in a Partner be personally
liable for monetary damages for any of the obligations of a Partner under this
Agreement. In no event shall any Partner be or become

                                      -17-


obligated personally to respond in monetary damages to the Partnership or any
other Partner with respect to this Agreement or on account of its being a
Partner except to the extent of its Partnership Interest, and any monetary claim
or judgment in favor of the Partnership or such other Partner shall be limited
accordingly so that the Partnership and such other Partner shall look only to
the Partner's Partnership Interest in the Partnership for the recovery of such
monetary claim or judgment and not to any of the Partner's other assets. To the
fullest extent permitted by law, the Partnership and each of the Partners waives
and disclaims any right it may have to proceed for monetary relief or damages
against the other Partners other than to the extent of the other Partners'
Partnership Interest in the Partnership. Nothing in this Section 11.10 shall
limit the right of any Partner to seek injunctive or other equitable relief
against any other Partner, the Partnership or any other Person. Each of the
Partners acknowledges and agrees that the covenants and obligations of or
applicable to such Partner hereunder shall be specifically enforceable by the
other Partners.

            11.11. Consents and Approvals. All consents, requests, notices and
approvals required hereunder shall be in writing, unless otherwise specifically
required herein.

                            [signature page follows]
