         Plan for such fiscal year or any amendment thereto, in either case as
         approved by the Management Committee pursuant to this Agreement or (ii)
         otherwise required by the Management Committee. Renwick shall

                                      -6-
<PAGE>   12

         contribute the Surplus Amount as defined in the Development Contract to
         fund the first Approved Business Plan and, unless otherwise agreed by
         the Management Committee, all other capital contribution shall be made
         pro rata in accordance with the Members' Sharing Ratios. Unless
         otherwise provided in the Business Plan, each such contribution shall
         be made in cash.

                  (c) If a Member does not contribute by the time required all
         or any portion of a Capital Contribution (the "Delinquent
         Contribution") that the Member is required to make as provided in this
         Agreement, the Company may, with notice to that Member (the "DELINQUENT
         MEMBER") and each of the other Members request that the Capital
         Contribution be made by the other Members. The Company shall give a
         written notice to the Delinquent Member and to the other Members
         specifying the amount of the Capital Contribution which has not been
         made. Each Member that elects to do so, shall, within five Business
         Days, notify the Company of the portion of such Delinquent Contribution
         the Member desires to make to the Company. If the Members, in the
         aggregate, elect to make contributions which would exceed the
         Delinquent Contribution, the amount to be contributed by each Member
         shall be reduced on a pro rata basis based on the amount each Member
         elected to contribute compared to the aggregate of the amounts all
         Members elected to contribute. The contribution made by a Member
         pursuant to this subparagraph (c) is referred to herein as a "Member's
         Optional Contribution."

         SECTION 7.2 NO LIABILITY FOR ADDITIONAL CONTRIBUTIONS. The liability of
each Member to the Company shall be limited to the amount of its Capital
Contribution made and to be made pursuant to Section 7.1, and no Member shall
have any further personal liability to contribute money to, or in respect of,
the liabilities or the obligations of the Company unless it agrees in writing to
make additional Capital Contributions to the Company, nor shall any Member be
personally liable for any obligations of the Company, except as may be provided
in the Act. No Member shall be entitled to the return of any part of its Capital
Contribution or to be paid interest in respect of either its Capital Account or
any Capital Contribution made by such Member. No unrepaid Capital Contribution
shall be deemed or considered to be a liability of the Company or any Member. No
Member shall be required to contribute or lend any cash or property to the
Company to enable the Company to return any Member's Capital Contribution to the
Member.

         SECTION 7.3 CAPITAL ACCOUNTS. A capital account ("CAPITAL ACCOUNT")
shall be established for each Member and shall be maintained in such a manner as
to correspond with the requirements of Treasury Regulations promulgated from
time to time under section 704(b) of the Code. The respective Capital Accounts
of the Members shall not bear interest.

         SECTION 7.4 ADJUSTMENT OF CAPITAL ACCOUNTS. If any Company property is
to be distributed in liquidation of the Company or a Membership Interest, the
Capital Accounts of the Members (and the amounts at which all Company properties
are carried on its books and records) shall, immediately prior to such issuance
or distribution, as the case may be, be adjusted (consistent with the provisions
of section 704(b) of the Code and the Treasury Regulations promulgated

                                      -7-
<PAGE>   13

thereunder) upward or downward to reflect any Unrealized Gain or Unrealized Loss
attributable to all Company properties (as if such Unrealized Gain or Unrealized
Loss had been recognized upon actual sale of such properties upon a liquidation
of the Company immediately prior to such issuance). If the Carrying Value of any
property of the Company is properly reflected on the books of the Company at a
value that differs from the adjusted tax basis of such property, this Section
7.4 shall be applied with reference to such value.

                                  ARTICLE VIII

                                  DISTRIBUTIONS

         SECTION 8.1 AMOUNT; TIMING.

                  (a) Except as otherwise provided herein or by the Act,
         Distributable Cash shall be distributed among the Members pro rata in
         accordance with their Sharing Ratios in such aggregate amounts and at
         such times as shall be determined by the Management Committee.

                  (b) Notwithstanding the foregoing, in the event a Member is a
         Delinquent Member and any other Member has made a Member's Optional
         Contribution with respect to the Delinquent Contribution of such
         Delinquent Member, all distributions to be made to such Delinquent
         Member shall first be made to the Members who have made such Member's
         Optional Contributions until such time as such Members have received an
         amount equal to 400% of the amount of their Member's Optional
         Contributions. In the event that more than one Member has made a
         Member's Optional Contribution with respect to a Delinquent
         Contribution, the distribution which would otherwise be made to the
         Delinquent Member of such Delinquent Contribution shall be divided
         among such Members pro rata based on the amount of each Member's
         Optional Contribution made with respect to such Delinquent Contribution
         compared to the aggregate amount of all Member's Optional Contributions
         with respect to such Delinquent Contribution. In the event there are
         outstanding Member's Optional Contributions with respect to more than
         one Delinquent Contribution of a Delinquent Member, all distributions
         which would otherwise be paid to that Delinquent Member shall first be
         paid to the Member or Members who made Member's Optional Contributions
         with respect to the oldest Delinquent Contribution of that Delinquent
         Member until such Members shall have received 400% of such Member's
         Optional Contributions and then with respect to the next oldest and in
         such order until all Members making Member's Optional Contributions
         with respect to Delinquent Contributions of such Delinquent Member have
         received 400% of the aggregate of all Delinquent Contributions of such
         Delinquent Member. When the amounts required to be paid pursuant hereto
         with respect to Member's Optional Contributions have been made with
         respect to all Delinquent Contributions of a Delinquent Member, such
         Delinquent Member shall cease being a Delinquent Member.

<PAGE>   14

         SECTION 8.2 FAILURE TO WITHDRAW. If any Member does not withdraw the
whole or any part of its share of any cash distribution made pursuant to Section
8.1, such Member shall not be entitled to receive any interest thereon without
the express written consent of the other Member.

         SECTION 8.3 TRANSFEROR/TRANSFEREE ALLOCATIONS. Unless otherwise agreed
in writing by a transferor and transferee of a Membership Interest herein,
Distributable Cash distributable with respect to any Membership Interest which
may have been transferred during any year shall be distributed to the holder of
such Membership Interest who was recognized as the owner on the date of such
distribution, without regard to the results of Company operations during the
year.

         SECTION 8.4 MEMBER ADVANCES. Notwithstanding the foregoing, if any
Member advances any funds or makes any other payment to or on behalf of the
Company, not required pursuant to the provisions hereof, to cover operating or
capital expenses of the Company which cannot be paid out of the Company's
operating revenues, such advance or payment shall be deemed a loan to the
Company by such Member, bearing interest from the date such advance or payment
was made until such loan is repaid at the Default Interest Rate. Notwithstanding
Section 8.1 above, all distributions of Distributable Cash shall first be
distributed to the Members making such loans until all such loans have been
repaid to such Members, together with interest thereon as above provided, and,
thereafter, the balance of such distributions, if any, shall be made in
accordance with the terms of Section 8.1 above. If distributions are
insufficient to repay and return all such loans as provided above, the funds
available from time to time shall first be applied to repay and retire the
oldest loan first and, if any funds thereafter remain available, such funds
shall be applied in a similar manner to remaining loans in accordance with the
order of the dates on which they were made; however, as to loans made on the
same date, each such loan shall be repaid pro rata in the proportion that such
loan bears to the total loans made on said date.

                                   ARTICLE IX

                          ALLOCATIONS OF INCOME, GAIN,

maintaining the Capital Accounts, all items of Company income, gain, loss,
deduction and credit shall be allocated among the Members pro rata in accordance
with their Sharing Ratios. For purposes of computing the amount of each item of
income, gain, deduction or loss to be charged or credited to the Capital
Accounts, the determination, recognition and classification of such item shall
be the same as its determination, recognition and classification for federal
income tax purposes, provided that:

                  (a) Any deductions for depreciation, cost recovery, or
         amortization attributable to any Company property shall be determined
         as if the adjusted basis of such property were

                                      -9-
<PAGE>   15

         equal to the Carrying Value of such property. Upon an adjustment to the
         Carrying Value of any Company property subject to depreciation, cost
         recovery, or amortization pursuant to Section 7.4, any further
         deductions for such depreciation, cost recovery, or amortization
         attributable to such property shall be determined as if the adjusted
         basis of such property were equal to the Carrying Value of such
         property immediately following such adjustment.

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

                  (c) All fees and other expenses incurred by the Company to
         promote the sale of a Membership Interest that can neither be deducted
         nor amortized under section 709 of the Code shall be treated as an item
         of deduction.

                  (d) Computation of all items of income, gain, loss and
         deduction shall be made without regard to any election under section
         754 of the Code which may be made by the Company and, as to those items
         described in section 705(a)(1)(B) or section 705(a)(2)(B) of the Code,
         without regard to the fact that such items are not includable in gross
         income or are neither currently deductible nor capitalizable for
         federal income tax purposes.

         SECTION 9.2 SPECIAL ALLOCATION.

                  (a) All items of deduction or loss attributable to the non-pro
         rata Capital Contribution to be made by Renwick pursuant to Section
         7.1(b) shall be allocated solely to Renwick.

                  (b) Once a Member that makes Member's Optional Contribution
         has received distributions under Section 8.1(b) in any amount equal to
         such Member's Optional Contribution, such Member shall be allocated
         gross income equal to the amount of all additional distributions
         received under Section 8.1(b) during any fiscal year of the Company as
         a result of such Member's Optional Contribution.

         SECTION 9.3 ALLOCATIONS FOR TAX PURPOSES.

                  (a) The Company shall, except to the extent such item is
         subject to allocation pursuant to subsection (b) below, allocate each
         item of income, gain, loss, deduction and credit, as determined for
         federal and other income tax purposes, in the same manner as such item
         was allocated for book purposes.

                  (b) The Company, for federal and other income tax purposes
         shall, in the case of Contributed Properties, allocate items of income,
         gain, loss, depreciation and cost recovery

                                      -10-
<PAGE>   16

         Company properties subject to depreciation, cost recovery or
         amortization are adjusted pursuant to Section 7.4 upon the issuance of
         Membership Interests for cash. If an existing Member acquires
         additional Membership Interests, such allocations shall apply only to
         the extent of his or its additional Membership Interests. No allocation
         under section 704(c) of the Code shall be charged or credited to a

this Article IX or other provisions of this Agreement.

                  (a) Renwick is designated tax matters partner ("TMP") as
         defined in section 6231(a)(7) of the Code. The TMP and the other Member
         shall use their best efforts to comply with responsibilities outlined
         in this Section 9.6 and in sections 6222 through 6232 of the Code
         (including any Treasury Regulations promulgated thereunder) and in
         doing so shall incur no liability to any other Member.

                  (b) If any Member intends to file a notice of inconsistent

         to the filing of such notice, notify the TMP of such intent and the
         manner in which the Member's intended treatment of a Company item is
         (or may be) inconsistent with the treatment of that item by the
         Company.

                  (c) No Member other than the TMP shall file a request pursuant

         where the TMP files such petition, he shall determine the forum in
         which such petition will be filed.

<PAGE>   19

                  may also appoint one or more individuals ("ALTERNATE
                  REPRESENTATIVES") with the power of substitution and authority
                  to act in place of its Representatives in case of the
                  unavailability thereof. Each Representative and Alternate
                  Representative shall be duly authorized to act on behalf of
                  and to bind the appointing Member. Each of Renwick and Harry
                  reserves the right to remove any one or more of its
                  Representative or Alternate Representatives, as the case may
                  be, and to appoint successors and substitutes therefor, from
                  time to time, and any such change shall be effective upon such
                  Member's delivering a written notice of such change to the
                  other Member.

                           (ii) In the event the individual serving as the
                  president/chief executive officer of the Company is not a
                  Representative, he or she shall be an additional member of the
                  Management Committee; however, that individual shall be a
                  nonvoting member.

                           (iii) Each Representative shall have one vote on all
                  matters to be decided by the Management Committee. Voting may
                  occur by voice vote at a meeting of the committee or by
                  written consent.

                           (iv) Any action of the Management Committee shall
                  require the affirmative vote of a majority of the persons on
                  the Management Committee. In addition, if, at any time, any
                  Member is a Delinquent Member, its Representative and
                  Alternate Representative(s) may not participate in the
                  Management Committee and all decisions shall be made by the
                  Representative or Alternate Representative(s) of the other
                  Member.

                           (v) To expedite the handling of Company business, it
                  is understood and agreed that any document executed by a
                  Representative or any Alternate Representative of each Member
                  shall, as to any third parties, be deemed to be the action of
                  the Member appointing such Representative or Alternate
                  Representative. Further, any Person dealing with the Company
                  may rely upon a certificate signed by a Representative or any
                  Alternate Representative of both Members as to:

to defer approval of a Business Plan, the Management Committee shall meet to
agree upon a person to either arbitrate or mediate the disagreement among the
Representatives. If the Management Committee agrees upon a person to arbitrate

shall be binding on all Members. If the Management Committee selects a mediator,
all Representatives shall have the opportunity to meet together with the
mediator on a date specified by the mediator upon 21 days' advance notice to the
Representatives, which notice can be waived. The Representatives, with the
assistance of the mediator, shall attempt in good faith to reach agreement on a
Business Plan. If the Management Committee can not agree on either an arbiter or

                                      -16-
<PAGE>   22

a mediator, Michael W. Conlon shall select a mediator and the Representatives
shall meet with such mediator in the same manner as set forth in the previous
sentence. If, notwithstanding completion of the foregoing, the Management
Committee has not agreed on a Business Plan and a Business Plan has not been
ordered by an arbiter, the Company shall be liquidated and terminated in
accordance with Article XVII.

         SECTION 14.4 COMPENSATION AND REIMBURSEMENT. The Management Committee
is not entitled to compensation for its services. Each Representative and
Alternate Representative shall be reimbursed by their respective Member for

         Committee. No officer need be a resident of the State of Delaware. Each
         officer shall hold his or her office for such terms and shall have such
         authority and exercise such powers and perform such duties as shall be
         determined from time to time by the Management Committee. Any number of
         offices may be held by the same individual. The salaries or other
         compensation, if any, of the officers and agents of the Company shall

         Committee may designate such other officers and assistant officers and
         agents as the Management Committee shall deem necessary.

         Management Committee, either with or without cause, in the discretion
         of the Management Committee; provided, that such removal shall be
         without prejudice to the contract rights, if any, of the person so
         removed. Designation of an officer shall not of itself create contract
         rights.

MEMBERS, THEIR RESPECTIVE AFFILIATES, NOR ANY OWNER, OFFICER, DIRECTOR, PARTNER,
EMPLOYEE OR AGENT OF THE MEMBERS OR THEIR RESPECTIVE AFFILIATES, SHALL BE

(x) A MEMBER OF THE MANAGEMENT COMMITTEE, A MEMBER OR AN AFFILIATE THEREOF, OR
(y) AN OFFICER, DIRECTOR, PARTNER, EMPLOYEE OR AGENT OF A MEMBER OR AN AFFILIATE
THEREOF, REGARDLESS OF WHETHER THE INDEMNITEE CONTINUES TO BE A MEMBER OF THE
MANAGEMENT COMMITTEE, A MEMBER OR AN AFFILIATE THEREOF OR AN OFFICER, DIRECTOR,
EMPLOYEE OR AGENT OF A MEMBER OR AN AFFILIATE THEREOF AT THE TIME ANY SUCH
LIABILITY OR EXPENSE IS PAID OR INCURRED, UNLESS THE ACT OR FAILURE TO ACT
GIVING RISE TO INDEMNITY HEREUNDER WAS PERFORMED OR OMITTED FRAUDULENTLY OR
CONSTITUTED GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

                  (b) The Company may purchase and maintain insurance on behalf
         of the Management Committee and such other Persons as the Management
         Committee shall determine against any liability that may be asserted
         against or expense that may be incurred by such Person in connection
         with the Company's activities, regardless of whether the Company would
         have the power to indemnify such Person against such liability under
         the provisions of this Agreement.

                  (c) Expenses incurred by any Indemnitee in defending any claim
         with respect to which such Indemnitee may be entitled to

         disposition of such claim, upon receipt of a written undertaking by or
         on behalf of such Indemnitee to repay the advanced amount of such
         expenses unless it is determined ultimately that the Indemnitee is
         entitled to indemnification by the Company under Section 14.7(a).

                  (d) The indemnification provided in this Section 14.7 is for
         the benefit of the Indemnitees and shall not be deemed to create any

relationship created hereby, in or to the business activities of the other
Members or of such Affiliates or to the income or proceeds derived therefrom,
and the pursuit of such business activities, even if competitive with the
business of the Company, shall not be deemed wrongful or improper. Any Member or
any Affiliate of a Member shall have the right to take for its own account or to
recommend to others any investment opportunity without being required to offer
the same to the other Members of the Company.

                                   ARTICLE XV

                        TRANSFER OF MEMBERSHIP INTERESTS

         SECTION 15.1 RESTRICTIONS ON TRANSFER. No Member shall have the right
to directly or indirectly transfer, sell, assign, pledge, hypothecate or
otherwise dispose of its interest in the Company, or any portion thereof,
without complying with the provisions of this Article XV. Any attempted transfer
or assignment of any interest in the Company in violation of the provisions of
this Article XV shall be void and of no force and effect.

         SECTION 15.2 PROCEDURES. Any Member who desires to transfer all or any
portion of its Membership Interest shall arrange for any permitted transferee to
be bound by the provisions of this Agreement, as it may then be amended,
including, specifically, this Article XV, by having such transferee execute two
counterparts of an instrument of assignment satisfactory in form and substance
to the other Member and by delivering the same to the Company together with any
such other information that may be required by counsel to the Company to
determine whether the proposed transfer violates applicable federal or state
securities or other laws or regulations. If and when the other requirements of
this Article XV are satisfied, the transferee shall become a substituted Member
as to the Membership Interest thus transferred effective as of the first day of
the

                                      -19-
<PAGE>   25

calendar month during which the Company actually receives the aforesaid
instrument of assignment executed by both the transferor and transferee and, in
the case of the transfer of a Member's entire Membership Interest, until such
time as the transferee is admitted to the Company as a Member of the Company,
the transferor Member shall not cease to be a Member of the Company. The
transferee shall be required to pay any and all reasonable filing and recording
fees, legal fees, accounting fees, and other charges and fees incurred by the
Company and its counsel as a result of such transfer.

         SECTION 15.3 CONSENT TO TRANSFER. Harry shall not directly or
indirectly transfer, sell, assign, pledge, hypothecate or otherwise dispose of
all or any portion of his interest in the Company if, as a result thereof, he
would own less than a 1% interest in the Company.

         SECTION 15.4 COMPLIANCE WITH SECURITIES LAWS. All Members acknowledge
that the Membership Interests have not been registered under (i) the Securities
Act of 1933, as amended (the "1933 ACT"), in reliance on the exemptions afforded
by Section 4(2) of the 1933 Act, or (ii) applicable state securities laws in
reliance on exemptions under such laws. Therefore, to preserve said exemptions
and notwithstanding anything contained herein to the contrary, the Members
hereby agree that Membership Interests shall be nontransferable and
nonassignable, except in compliance with the registration provisions of the 1933
Act and the Act, or an exemption or exemptions therefrom, and any attempted or
purported transfer or assignment in violation of the foregoing shall be void and
of no effect. Accordingly, as an additional condition precedent to any
assignment or other transfer of any interest in the Company, the Management
Committee may require an opinion of counsel satisfactory to the Management
Committee that such assignment or transfer will be made in compliance with the
registration provisions of the 1933 Act and applicable state securities laws or
exemption(s) therefrom, and such transferor or assignor shall be responsible for
paying said counsel's fee for the opinion.

         SECTION 15.5 BUY-OUT. Upon the happening of a Buy-Out Event, as defined
below, Renwick shall, within 30 days of receipt of notice of the Buy-Out Event,
make an offer to purchase all of the interests in the Company not held by
Renwick (the "Subject Interests"). The offer, which shall be in writing and
shall be delivered to Harry, unless Harry shall be deceased or mentally
incapacitated, in which case it shall be delivered to the executor of his estate
or his legal guardian, shall specify a dollar amount in cash for the Subject
Interests. Harry, or his executor or legal guardian as the case may be, shall
have thirty days in which to advise Renwick in writing whether the holders of
the Subject Interests elect to sell the Subject Interests for the amount offered
by Renwick or elect to buy Renwick's interest in the Company for cash in an
amount equal to the price offered by Renwick divided by the Subject Interests
times Renwick's interest in the Company. Within ten business days of the notice
to Renwick indicating whether the holders of the Subject Interests elect to sell
the Subject Interests to Renwick or elect to buy from Renwick its interest in
the Company, Renwick and the holders of the Subject Interests shall complete the
sale and purchase by the purchaser delivering the purchase price in cash by wire
transfer to the account specified by the seller and the seller delivering such
documents of transfer evidencing the sale and transfer of the applicable
interests in the Company as the purchaser may reasonably request.

         SECTION 15.6 BUY-OUT EVENT. For purpose of this Agreement, a Buy-Out
Event shall mean any of the following:

                  (a) The death or mental or physical incapacity of Harry such
         that he is unable to perform his normal working duties for a period of
         more than six months.

                  (b) The election by Harry to sell so much of his interest in
         the Company so that he will own less than a 1% interest in the Company.
         If Harry decides to make any such sell, prior to his doing so, he must
         give written notice of a Buy-Out Event to Renwick and in such notice
         must specify the terms of all offers or reasonably anticipated offers
         to purchase all of the Company, including all or substantially all of
         the assets of the Company, or to purchase any interests in the Company.

                  (c) Harry shall desire to have all of the interest in the
         Company or, all or substantially all of its assets sold to a person or
         group of persons. In this case, Harry shall give written notice to
         Renwick of a Buy-Out Event and in such notice shall specify the terms
         on which any person or group of persons, specifying such person or
         group of persons, proposal to purchase all or substantially all of the
         assets of the Company or the entire interest in the Company. If, within
         10 business days of receipt of such notice, Renwick advises Harry that
         it concurs with the proposed sale, the notice from Harry shall cease to
         be considered a notice of a Buy-Out Event, and Renwick and Harry shall
         proceed in good faith to close the sale of the entire interest in the
         Company or of all or substantially all of the assets of the Company.

                  (d) In the event that the Management Committee does not
         approve the Business Plan, the terms of Section 14.3 have been
         satisfied, and the Company is required to be liquidated pursuant to
         Section 14.3, either Harry or Renwick may declare and give notice of a
         Buy-Out Event provided such notice is given within 30 days of the final
         meeting with the mediator as contemplated by Section 14.3.

                                   ARTICLE XVI

         SECTION 16.1 EVENTS OF DISSOLUTION. The happening of any one of the
following events shall work an immediate dissolution of the Company:

                  (a) The death, retirement, resignation, expulsion, bankruptcy
         or dissolution of a Member unless the business of the Company is
         continued by the written consent of the remaining Member within 90 days
         following the occurrence of any such event;

                                      -21-
<PAGE>   27

                  (b) The receipt by the Company of the final payment due on the
         sales price of all or substantially all the assets of the Company or
         the Company's business following the Company's sale thereof;

                  (c) The agreement by all of the Members to dissolve;

                  (d) Inability to agree on a Business Plan;

                  (e) The expiration of the term of the Company as provided in
         Article VI of this Agreement, unless all Members agree to extend the
         term of the Company past the date set forth in Article VI; and

                  (f) The entry of a decree of judicial dissolution underss.
         18-802 of the Act.

Each Member covenants and agrees that it will not retire, resign or voluntarily
dissolve, without the prior written consent of the other Member, which consent
may be granted or withheld in the sole discretion of the other Member.

         SECTION 16.2 OPTION TO PURCHASE INTEREST OF BANKRUPT MEMBER.

                  (a) If within 90 days of the Bankruptcy of any Member, the
         other Member elects to continue the business of the Company, the
         Bankruptcy shall be deemed to be an offer by the bankrupt Member of its
         Membership Interest to the other Member at a price equal to the fair
         market value of such bankrupt Member's Membership Interest determined
         by agreement between the bankrupt Member (or its legal representative)
         and the other Member; provided, however, if those Persons do not agree
         on the fair market value on or before the 30th day following the
         election of the other Member to continue the business of the Company,
         such value shall be determined pursuant to the appraisal procedures set
         forth in Section 16.2(b).

                  (b) If the Members cannot agree on the fair market value of a
         Membership Interest or one or more of the assets or businesses of the
         Company within 15 days after such value is to be determined under any
         provisions of this Agreement, either Member, by notice to the other,
         may require the determination of such fair market value to be made by
         an independent appraiser specified in a written notice to the other
         Member. If the Member receiving that notice objects to the independent
         appraiser designated in that notice on or before the 15th day following
         receipt, and the Members otherwise fail to agree on an independent
         appraiser, either Member may petition the United States District Judge
         for the Southern District of Texas then senior in service to designate
         an independent appraiser. The determination of the fair market value by
         the independent appraiser, however designated, shall be final and
         binding on all parties. Each Member shall be responsible for 50% of the
         cost of such appraisal.

powers) to the extent necessary or desirable in the good faith judgment of the
Liquidator to carry out the duties and functions of the Liquidator hereunder for
and during such period of time, not to exceed two (2) years after the date of
dissolution of the Company, as shall be reasonably required in the good faith
judgment of the Liquidator to complete the liquidation and dissolution of the
Company as provided for herein, including, without limitation, the following
specific powers:

                  (a) The power to continue to manage and operate any business

         proceedings, excluding, however, the power to make and enter into
         contracts which may extend beyond the period of liquidation.

                  (b) The power to make sales and incident thereto to execute
         deeds, bills of sale, assignments and transfers of assets and
         properties of the Company; provided, that the Liquidator may not impose
         personal liability upon any of the Members under any such instrument.

                  (c) The power to borrow funds as may, in the good faith
         judgment of the Liquidator, be reasonably required to pay debts and
         obligations of the Company or operating expenses, and to execute and/or
         grant deeds of trust, mortgages, security agreements, pledges and
         collateral assignments upon and encumbering any of the Company
         properties as security for repayment of such loans or as security for
         payment of any other indebtedness of the Company; provided, that the
         Liquidator shall not have the power to create any personal obligation
         on any of the Members to repay such loans or indebtedness other than
         out of available proceeds of foreclosure or sale of the properties or
         assets as to which a lien or liens are granted as security for payment
         thereof.

                  (d) The power to settle, release, compromise or adjust any
         claims asserted to be owing by or to the Company, and the right to

         SECTION 17.2 RESERVES. In making payment or provision for payment of
all debts and liabilities of the Company and all expenses of liquidation, the
Liquidator may set up such cash reserves as the Liquidator may deem reasonably
necessary for any contingent liabilities or obligations of the Company. Upon the
satisfaction or other discharge of such contingency, the amount of the reserves
not retired, if any, will be distributed in accordance with this Article.

         SECTION 17.3 SALE OF ASSETS; DISTRIBUTION OF PROCEEDS. Upon the winding
up and termination of the business and affairs of the Company, its assets (other
than cash) shall be sold, its liabilities and obligations to creditors and all
expenses incurred in its liquidation shall be paid (either by payment or the
making of reasonable provision for payment). All items of Company income, gain,
loss or deduction shall be credited or charged to the Capital Accounts of the
Members in accordance with the applicable provisions of Article IX. Thereafter,
the net proceeds from such sales (after deducting all selling costs and expenses
in connection therewith), together with the reserve account referred to in
Section 17.2 above, shall be distributed among the Members in accordance with
their respective positive balances in their Capital Accounts.

         SECTION 17.4 FINAL ACCOUNTING. Within a reasonable time following the
completion of the liquidation of the Company's properties, the Liquidator shall

date of complete liquidation, each Member's pro rata portion of distributions
pursuant to Section 17.3, and the amount retained as reserves by the Liquidator
pursuant to Section 17.2.

         SECTION 17.5 RECOURSE LIMITED TO COMPANY ASSETS. Each holder of an
interest in the Company shall look solely to the assets of the Company for all
distributions with respect to the Company and his Capital Contribution thereto
(including the return thereof) and share of profits or losses thereof, and shall
have no recourse therefor (upon dissolution or otherwise) against the Company,
the Members or the Liquidator. No holder of an interest in the Company shall
have any right to demand or receive property other than cash upon dissolution
and termination of the Company.

         SECTION 17.6 TERMINATION. Upon the completion of the liquidation of the
Company and the distribution of all Company funds, the existence of the Company
shall terminate and the Liquidator shall (and is hereby given the power and
authority to) execute, acknowledge, swear to and record all documents required
to effectuate the dissolution and termination of the Company. No Member shall be
required to restore any deficit balance existing in its Capital Account upon the
liquidation and termination of the Company.
