         Section 2038 of the Act.

         (2) Upon dissolution of the Company, the business and affairs of the
Company shall terminate, and the assets of the Company shall be liquidated under
this Article VII. The Members shall act as liquidator. The cost of dissolution
shall be borne as a Company expense.

         (3) Dissolution of the Company shall be effective as of the day on
which the event occurs giving rise to the dissolution, but the Company shall not
terminate until there has been a winding up of the Company's business and
affairs, and the assets of the Company have been distributed as provided in
Section 7.2.

         (4) Upon dissolution of the Company, the Members may cause any part or
all of the assets of the Company to be sold in such manner as the Members shall
determine in an effort to obtain the best prices for such assets; provided,
however that the Members may distribute assets of the Company in kind to the
Members to the extent practicable.

         1.49 Distribution of Assets Upon Dissolution. In settling accounts
after dissolution, the assets of the Company shall be paid in the following
order:


                                       16


         (1) First, to creditors, in the order of priority as provided by
applicable law, except those to Members on account of their Capital
Contributions;

         (2) Second, an amount equal to the then remaining credit balances in
the Capital Accounts of the Members shall be distributed to the Members in
proportion to the amount of such balances; and

         (3) Third, any remainder shall be distributed to the Members Pro Rata.

         1.50 Distributions in Kind. If any assets of the Company are
distributed in kind, such assets shall be distributed to the Members entitled
thereto as tenants common in the same proportions as the Members would have been
entitled to cash distributions if such property had been sold for cash and the
net proceeds thereof distributed to the Members. In the event that
distributions, in kind are made to the Members upon dissolution and liquidation
of the Company, the Capital Account balances of such Members shall be adjusted
to reflect the Members' allocable share of gain or loss which would have
resulted if the distributed property had been sold at its fair market value. All
distributions in kind to the Members shall be made subject to the liability of
each distributee for costs, expenses and liabilities theretofore incurred or for
which the Company has committed prior to the date of termination and those
costs, expenses and liabilities shall be allocated to the distributee pursuant
to Section 7.3. The distribution of cash or property to a Member in accordance
with the provisions of this Section 7.3 constitutes a complete return to the
Member of its Capital Contributions and a complete distribution to the Member of
its Membership Interest and all the Company's property. To the extent that a
Member returns funds to the Company, it has no claim against the other Members
for those funds.

         1.51 Articles of Dissolution. When all liabilities and obligations of
the Company have been paid or discharged, or adequate provision has been made
therefor, and all of the remaining property and assets of the Company have been
distributed to the Members according to their respective rights and interests,
the Articles of Dissolution shall be executed on behalf of the Company by an
authorized Member and shall be filed with the Secretary of State of Oklahoma,
and the Members shall execute, acknowledge and file any and all other
instruments necessary or appropriate to reflect the dissolution and termination
of the Company.

         1.52 Deficit Capital Accounts. Notwithstanding anything to the contrary
contained in this Agreement, and notwithstanding any custom or rule of law to
the contrary, no Member shall be required to restore to the Company or pay to
any other Member any deficit that may exist in the Capital Account of the Member
upon dissolution and liquidation of the Company.

                                  ARTICLE VIII.
                        TRANSFER OF MEMBERSHIP INTERESTS

         1.53 Restrictions on Transfers. Except as expressly permitted or
required by this Agreement, no Member shall Transfer all or any portion of its
Membership Interests or any rights therein without the approval of a Majority in
Interest of the Members. Any Transfer or attempted Transfer by any Member in
violation of the preceding sentence shall be null and void and of no effect
whatever. Each Member hereby acknowledges the reasonableness of the restrictions
on Transfer imposed by this Agreement in view of the Company purposes and the
relationship of the Members. Accordingly, the restrictions on Transfer contained
herein shall be specifically enforceable. Each Member hereby further agrees to
hold the Company and each Member (and each Member's successors and assigns)
wholly and completely harmless from any cost, liability, or damage (including,
without limitation, liabilities for income taxes and costs of enforcing this
restriction or this indemnity) incurred by any of such indemnified Persons as a
result of a Transfer or an attempted Transfer in violation of this Agreement

         1.54 Permitted Transfers. Subject to the conditions and restrictions
set forth in Section 8.4, a Member may at any time Transfer all or any portion
of its Membership Interests to (i) any other Member, (ii) the transferor's
administrator, trustee, or other legal representative to whom the Membership
Interests are transferred involuntarily by operation of law, (iii) with the
approval of a Majority in Interest of the Members, which consent may be withheld
or granted for any reason, to any other Person that qualifies as a Member, or
(iv) in compliance with the terms and provisions of Section 8.3 (any such
Transfer being referred to in this Agreement as a "Permitted Transfer").

         1.55 Right of First Refusal.

         (a) No Member shall Transfer any Membership Interest to any other party
by sale, gift or otherwise, unless it (the "Selling Member") has received from
such other party (the "Offerer") a bona fide, noncollusive offer (the "Offer")
to buy such Membership interest (the "Offer Interests") for all cash, which has
been verified in writing by the Offeror. Before making such a transfer, the
Selling Member shall first give notice in writing to the Company informing it of
its right of first refusal to purchase such Membership Interest, upon the terms
and conditions set out in the Offer. Such notice shall include a true and
correct copy of the Offer and the financial statements of the Offeror or a bona
fide lender's commitment in writing evidencing the Offerer's ability to pay.

         (b) Upon receipt of written notice from the Selling Member under this
section, the Managers shall call a special meeting of the Members to be held
within thirty (30) days from the date of receipt of such notice to determine
whether a Majority in Interest of the Members (excluding the Selling Member)
desires that the

                                       18


Company purchase any portion or all of the Offer Interests. The Company shall
have ninety (90) days from the date of the notice to the Company of the Offer to
exercise, by written notice, the right of the Company to purchase any or all of
the Offer Interests. If no written notice to the Selling Member is given, or the
special meeting is not held within the prescribed time limits, the Company shall
be deemed to have failed to exercise its option to purchase the Offer Interests.

         (c) Once the Company has exercised its option under this Section 8.3 or
has failed or is deemed to have failed to exercise its option under this Section
8.3, the Selling Member shall give notice in writing to the Members informing
them of their rights of first refusal to purchase all unpurchased Offer
Interests (the "UNPURCHASED OFFER INTERESTS") upon the terms and conditions set
out in the Offer. Such notice shall include a true and correct copy of the Offer
and the financial statements of the Offeror or a bona fide lender's commitment
in writing evidencing the Offerer's ability to pay. Within thirty (30) days of
receipt of the notice from the Selling Member that the Company did not elect to
purchase all of the Offer Interests in accordance with this Section 8.3, each of
the Members (excluding the Selling Member) shall have the option to purchase, in
accordance with the terms of the Offer, up to a portion of the Unpurchased Offer
Interests equal to the number of Unpurchased Offer Interests multiplied by the
ratio of the Membership Interest of such Member to the aggregate Membership
Interests of all Members (excluding the Selling Member) who desire to purchase
up to a portion of the Unpurchased Offer Interests. A Member desiring to
exercise its option under this Section 8.3 shall give written notice thereof to
the Selling Member, to be dated and sent no later than thirty (30) days after
such Member's receipt of notice of the Offer and the Unpurchased Offer
Interests. Failure to so notify the Selling Member proposing this Offer shall be
deemed a failure to exercise such option.

         (d) Once the Company and all of the other Members have exercised their
options under this Section 8.3 or have failed and are deemed to have failed to
exercise their options under this Section 8.3, then the Selling Member may sell,
within thirty (30) days after such date, to the Person or entity making the
Offer such Membership Interest which the Company and the other Members have not
elected to purchase pursuant to this Section 8.3 on the terms in the Offer.
After the expiration of such 30-day period, the Selling Member's right to sell
any of its Membership Interest pursuant to this Section 8.3 shall terminate, and
the terms of Section 8.3 shall again become effective.

         1.56 Conditions to and Restrictions on Permitted Transfers. A Transfer
shall not be treated as a Permitted Transfer under Section 8.2 unless and until
the following conditions are satisfied:

         (1) Execution of Agreements. Except in the case of a Transfer of
Membership Interests involuntarily by operation of law, the transferor and
transferee execute and deliver to the Company documents and instruments of


                                       19



conveyance necessary or appropriate in the opinion of counsel to the Company to
effect the Transfer and to confirm the agreement of the transferee to be bound
by the provisions of this Article VIII. In any case not described in the
preceding sentence, the Transfer must be confirmed by presentation to the
Company of legal evidence of the Transfer, in form and substance satisfactory to
counsel to the Company. In all cases, the Company shall be reimbursed by the
transferor and/or transferee for all costs and expenses that if the Company
reasonably incurs in connection with the Transfer.

         (2) Opinion of Counsel. Except in the case of a Transfer involuntarily
by operation of law, the transferor shall furnish to the Company an opinion of
counsel satisfactory to the Company that the Transfer shall not cause the
Company to terminate as a partnership for federal income tax purposes. The
Members may waive this requirement.

         (3) Required Information. The transferor and transferee shall furnish
to the Company the transferee's taxpayer identification number and sufficient
information to determine the transferee's initial tax basis in the Membership
Interests Transferred, and any other information reasonably necessary to permit
the Company to file all required federal and state tax returns and other legally
required information statements or returns. Without limiting the generality of
the foregoing, the Company is not required to make any distribution otherwise
provided for in this Agreement with respect to any Transferred Membership
Interests until it has received that information.

         (4) Restrictions. Except in the case of a Transfer of Membership
Interests involuntarily by operation of law, either (i) the Membership Interests
shall be registered under the Securities Act of 1933, as amended, and any
applicable state securities laws, or (ii) the transferor shall provide an
opinion of counsel satisfactory to the Company, to the effect that the Transfer
is exempt from applicable registration requirements and will not violate any
applicable laws regulating the Transfer of securities.

         1.57 Prohibited Transfers. Any purported Transfer of Membership
Interests that is not a Permitted Transfer is null and void and of no effect
whatsoever, provided that, if the Company is required to recognize a Transfer
that is not a Permitted Transfer (or if the Company, by the approval of a
Majority in Interest of the Members and in its sole discretion, elects to
recognize a Transfer that is not a Permitted Transfer), then the Membership
Interest Transferred shall be strictly limited to the transferor's rights to
allocations and distributions provided by this Agreement with respect to the
Transferred Membership Interests, which allocations and distributions may be
applied (without limiting any other legal or equitable rights of the Company) to
satisfy the debts, obligations, or liabilities for damages that the transferor
or transferee of the Interests may have to the Company. In the case of a
Transfer or attempted Transfer of Membership Interests


                                       20


that is not a Permitted Transfer, the parties engaging or attempting to engage
in the Transfer shall, indemnify and hold harmless the Company and the other
Members from all cost, liability, and damage that any of the indemnified Persons
incurs (including, without limitation, incremental tax liability and attorneys'
fees and expenses) as a result of the Transfer or attempted Transfer and efforts
to enforce the indemnity granted hereby.

         1.58 Rights of Unadmitted Assignees. A Person who acquires one or more
Membership Interests but who is not admitted as a Member pursuant to Section 8.7
is entitled only to allocations and distributions with respect to the Membership
Interests in accordance with this Agreement, but, unless otherwise required by
the Act, (i) has no right to any information or accounting of the affairs of the
Company, (ii) is not entitled to inspect the books or records of the Company,
and (iii) has none of the rights of a Member under the Act or this Agreement.

         1.59 Admission of Assignees as Members. Subject to the other provisions
of this Article VIII, a transferee of Membership Interests may be admitted to
the Company as a Member only on satisfaction of the conditions set forth below
in this Section 8.7:

         (1) The admission is approved by a Majority in Interest of the Members,
which consent may be withheld or granted in each Member's sole discretion;

         (2) The Membership Interests with respect to which the transferee is
being admitted were acquired by means of a Permitted Transfer;

         (3) The transferee becomes a party to this Agreement as a Member and
executes the documents and instruments reasonably required by the Managers as
necessary or appropriate to confirm the transferee as a Member in the Company
and the transferee's agreement to be bound by the terms and conditions hereof;

         (4) The transferee pays or reimburses the Company for all reasonable
legal, filing, and publication costs that the Company incurs in connection with
the admission of the transferee as a Member with respect to the Transferred
Membership Interests; and

         (5) The transferee qualifies as a Member and provides the Company with
evidence satisfactory to counsel for the Company of the power and authority of
the transferee to become a Member and to be bound by the terms and conditions of
this Agreement.

         The admission of any Person as an additional Member becomes effective
on the first day of the month immediately following the date on which the name
of the Person is recorded on the books and records of the Company and the
admission has received the approval of a Majority in Interest of the Members.


                                       21


         1.60 Representations and Legend.

         (1) Representation. Each Member hereby represents and warrants, and
covenants and agrees with the Company for the benefit of the Company and all
Members, that (i) it is not currently making a market in Membership Interests,
(ii) it will not transfer any Interest on an established securities market or a
secondary market (or the substantial equivalent thereof) within the meaning of
Code Section 7704(b) (and any regulations, proposed regulations, revenue
rulings, or other official pronouncements of the Internal Revenue Service or
Treasury Department that may be promulgated or published thereunder), and (iii)
if such regulations, revenue rulings, or other pronouncements treat any or all
arrangements which facilitate the selling of partnership interests and which are
commonly referred to as "matching services" as being a secondary market or
substantial equivalent thereof, it will not Transfer any Interest through a
matching service that is not approved by a Majority in Interest. Each Member
further agrees that it will not Transfer any Membership Interest to any Person
unless the Person agrees to be bound by this Section 8.8(a) and to Transfer
Interests only to Persons who agree to be similarly bound.

         (2) Legend. Each Member hereby represents and warrants to the Company
that the Member's acquisition of Interests hereunder is made as a principal for
the Member's own account and not for resale or distribution. Each Member hereby
agrees that the following or a similar legend may be placed on any counterpart
of this Agreement, the Certificate, or any other document or instrument
evidencing ownership of Membership Interests:


                  THE MEMBERSHIP INTERESTS REFERENCED HEREIN HAVE BEEN
                  ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
                  STATE SECURITIES LAWS. WITHOUT REGISTRATION, THESE
                  SECURITIES MAY NOT BE SOLD, PLEDGED, HYPOTHECATED, OR
                  OTHERWISE TRANSFERRED AT ANY TIME WHATSOEVER, EXCEPT
                  ON DELIVERY TO THE COMPANY OF AN OPINION OF COUNSEL
                  SATISFACTORY TO THE MANAGERS OF THE COMPANY THAT
                  REGISTRATION IS NOT REQUIRED FOR THE TRANSFER, OR THE
                  SUBMISSION TO THE MANAGERS OF THE COMPANY OF OTHER
                  EVIDENCE SATISFACTORY TO THE MANAGERS TO THE EFFECT
                  THAT ANY TRANSFER WILL NOT BE IN VIOLATION OF THE
                  SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE
                  STATE SECURITIES LAWS OR ANY RULE OR REGULATIONS
                  PROMULGATED THEREUNDER. ADDITIONALLY,

                                       22



                  ANY SALE OR OTHER TRANSFER OF MEMBERSHIP INTEREST IS
                  SUBJECT TO CERTAIN RESTRICTIONS THAT ARE SET FORTH IN
                  THIS AGREEMENT.

         1.61 Distributions and Allocations. If a Membership Interest is
Transferred, during any accounting period in compliance with the provisions of
this Article VIII, Profits, Losses, each item thereof, and all other items
attributable to the Membership Interest for the period shall be divided and
allocated between the transferor and the transferee by taking, into account
their varying interests during the period in accordance with Code Section
706(d), using any conventions permitted by law and selected by the Members. All
distributions on or before the date of the Transfer shall be made to the
transferor, and all distributions thereafter shall be made to the transferee.
Solely for purposes of making the allocations and distributions, the Company
shall recognize the Transfer not later than the end of the calendar month during
which it is given notice of the Transfer, but if the Company does not receive a
notice stating the date the Interest was Transferred and the other information
reasonably required by the Members within thirty (30) days after the end of the
accounting period during which the Transfer occurs, then all of the items shall
be allocated, and all distributions shall be made, to the Person who was the
owner of the Membership Interest, according to the books and records of the
Company, on the last day of the accounting period during which the Transfer
occurs. Neither the Company nor any Member shall, incur any liability for
making, allocations and distributions in accordance with the provisions of this
Section 8.9, whether or not any Member or the Company has knowledge of any
Transfer of ownership of any Membership Interest.

         1.62 Tax Matters. On the Transfer of all or part of a Membership
Interest in the Company, at the request of the transferee of the interest, the
Members may cause the Company to elect, pursuant to Section 754 of the Code to
adjust the tax basis of the Company's properties as provided by Sections 734 and
743 of the Code.

                                   ARTICLE IX.
                                     BUY-OUT

         9.1 Buy-out Events. This Article IX shall apply to any of the following
events (each a "Buy-out Event"):

         (a) Any (i) Bankruptcy of a Member, (ii) institution of legal
proceedings because or by reason of the insolvency of a Member unless dismissed
without a finding of insolvency, (iii) levy upon the shares of Interest held by
a Member by a creditor or claimant, or any other seizure or sale by legal
process, if it is determined by legal counsel for the Company that such levy is
made in good faith and based upon a bona fide claim, (iv) the general assignment
for the benefit of creditors, (v) the filing, or consent to the filing of, a
petition under any federal or state insolvency, bankruptcy, reorganization or
similar law (collectively "Bankruptcy Law") or

                                       23



petition for, or consent to, the taking of possession by a trustee, receiver or
similar official of any of his or her assets unless dismissed, terminated or
lifted within sixty (60) days thereafter without impact on ownership of
Interest, (vi) the adjudication as bankrupt or insolvent under any Bankruptcy
Law by a judgment that has become final, or (vii) the attachment, sequestration,
foreclosure, turnover order, writ of execution or garnishment, or any other
method of seizure to be levied, against any Interest without such attachment,
sequestration, foreclosure, turnover order, writ of execution, garnishment of
other method of seizure having been terminated, annulled or reversed within
thirty (30) days after the commencement or effectiveness thereof; or

         (b) Any proposed or attempted pledge, sale, exchange, gift or other
disposition or transfer of all or any of the Membership Interest owned by a
Member in any manner whatsoever unless authorized hereunder or approved by a
Majority in Interest of the Members; or

         (c) The completion of divorce proceedings by or against a Member or a
partner or owner of a Member, or the entering into any property settlement
arrangement or agreement in connection therewith, pursuant to which such
Member's or partner's or owner's interest in the Member is to be diluted,
lessened or impaired; provided, however, that if the Member or partner or owner
is able to produce evidence reasonably satisfactory to the remaining Members
that his or her interest in the Membership Interest or the Member is not
community property, including as a result of purchase of the spouse's interest
in the interest, none of the events described in this paragraph (C) will be
deemed to constitute a Buy-out Event; or

         (d) A Member shall withdraw from being a Member of the Company; or

         (e) A Member shall be removed from Membership; or

         (f) A Member shall commit a Default.

In each case, the Member with respect to whom a Buy-out Event has occurred is
referred to herein as the "Affected Member." The Affected Member shall
automatically cease to be a Member upon the occurrence of a Buy-out Event.

         For purposes of this Article, any determination made by a Majority in
Interest of the Members that a Buy-out Event has occurred shall be conclusive
and binding upon the parties hereto and their respective successors or assigns;
such determination shall, however, be subject to the standards of reasonableness
and good faith, in accordance with the purposes of this Article concerning the
desired continuation of management and control of the Company. It shall not be a
requirement hereunder that the Members make a determination in every instance
that a Buy-out Event has so occurred, but such determination shall be made in
those instances in which there may be some question as to whether a Buy-out
Event


                                       24


did in fact occur. Upon such determination by the Members that a Buy-out Event
has in fact occurred, in order to inform the Member of such occurrence, the
Company shall deliver a written notice stating that such a Buy-out Event has
occurred, the date thereof and the reasons for the determination, to the Member
or his or her legal representative.

         9.2 Procedure for Member-Related Buy-out Events. An Affected Member (or
its representative) shall promptly give notice of the Buy-out Event to the
Company and the other Members. Each of the other Members shall have the option
to acquire the Membership Interests of the Affected Member by notifying the
Affected Member (or its representative) of such exercise within thirty (30) days
following such Member's receipt of the Affected Member's notice. Any Member that
does not respond during the applicable period shall be deemed to have waived its
right. If more than one Member exercises its right, each exercising Member shall
participate in the purchase in the same proportion that its ownership bears to
the aggregate ownership of all exercising Members (or on such other basis as the
exercising Members may mutually agree). The Purchase Price (defined in
accordance with Section 9.3) paid by a Member exercising the option hereunder
shall be added to and deemed a part of the Member's Capital Contribution. The
Company shall be obligated to buy the Affected Member's Memberships-Interests
that are not the subject of exercise by Members of the option granted to Members
(other than the Affected Member) under this Section 9.2 or that are not actually
purchased by such Members.

         9.3 Purchase Price. If a Member sells its Membership Interest pursuant
to this Article IX, the Purchase Price of such Membership Interest shall be the
lesser of (i) the amount of Capital Contribution made by the Member to purchase
such interest, or (ii) the book value of such interest as determined by the
Company's accountant. At the closing, the Persons who are purchasing the
Membership Interest shall pay the Affected Member the Purchase Price in cash or,
at the Company's election, the Company may execute a promissory note to the
Affected Member with a term not to exceed one (1) year and accruing interest at
the Prime Interest Rate.

         9.4 Closing. If an option to purchase is exercised in accordance with
the other provisions of this Article IX, the closing of such purchase shall
occur at the principal place of business of the Company on the ninetieth (90th)
day after the purchasers receive notice of the Buy-Out Event from the Affected
Member unless the parties to such closing agree upon a different place or date.
At the closing, (a) the Affected Member shall execute and deliver to the
purchasers (i) an assignment of the Affected Member's Membership Interests (as
applicable), in form and substance reasonably acceptable to the purchasers,
containing a general warranty of title as to such Membership Interests
(including that such Membership Interests are free and clear of any
encumbrances), and (ii) any other instruments reasonably requested by the
purchasers to give effect to the purchase; and (b) the purchasers


                                       25


shall deliver to the Seller (i) the portion of the Purchase Price required to be
paid at the closing, in immediately available funds, or (ii) an unsecured
promissory note reflecting the payment terms established in Section 9.3.

                                   ARTICLE X.

binding upon the Member who executed the same, but all of such counterparts
shall constitute the same Agreement.

         1.71 Checks. All checks and demands for money and notes of the Company
shall be signed by such Managers or representatives of the Company as a Majority
in Interest of the Members may from time to time designate.

         1.72 Accounts. The Members shall establish and maintain one or more
separate bank and investment accounts and arrangements for the Company funds in
the Company name with financial institutions and firms that the Members may
determine. The Managers may not commingle the Company's funds with the funds of
any Member.

         1.73 Invalid Provisions. If any provision of this Agreement is held to
be illegal, invalid, or unenforceable under present or future laws, such
provision shall be fully severable; this Agreement shall be construed and
enforced as if such illegal, invalid, or unenforceable provision had never
comprised a part hereof; and the remaining provisions hereof shall remain in
full force and effect and shall not be affected by the illegal, invalid, or
unenforceable provision or by its severance herefrom. Furthermore, in lieu of
such illegal, invalid, or unenforceable provision there shall be added
automatically as a part of this Agreement a provision as similar in terms to
such illegal, invalid, or unenforceable provision as may be possible and be
legal, valid, and enforceable.

         1.74 Entire Agreement. This Agreement constitutes the entire agreement
of the Members relating to the Company and supersedes all prior contracts or
agreements with respect to the Company, whether oral or written.

         1.75 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 Company 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 Company.
Failure on the part of a Person to complain of any act of any Person or to
declare any Person in default with respect to the Company, 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.

this Agreement each Member acknowledges that it has actual notice of (a) all of

restrictions on the transfer of Membership Interests set forth in Article VIII
and (b) all of the


                                       27

Agreement constitutes adequate notice of all such provisions.
