1)   Description of all services performed by the Numanco Companies
during the reporting period

       *    The Numanco Companies provided services in each of the following
            four areas: health physics services, mechanical services, quality
            assurance services and training services. Of the services listed,
            over 99% of all work performed was in commercial nuclear power
            plants within the United States. Of the four types of services
            listed above, over 90% of revenues were derived from the provision
            of health physics services.

       *    As previously reported, the Numanco Companies continue to provide
            health physics and mechanical personnel as a result of a joint
            venture with a third party. This joint venture provides turn-key
            tank cleaning to utilities, heavy industry, the U.S. Department of
            Energy (DOE) and the U.S. Department of Defense. This venture has
            not received any significant work to date, but it is bidding on some
            projects for the DOE, one electric utility and several
            petro-chemical facilities.

       *    During the period, the Numanco Companies assumed the operations and
            acquired the assets of its joint venture partner in the tank
            cleaning business described above. The joint venture partner owned
            the submersible pumps and provides the proprietary and patented
            technology used in the tank cleaning operations. The Numanco
            Companies have spent considerable time and expense qualifying the
            technology for use at DOE sites. The Numanco Companies are using
            its mechanical contract labor, existing management and
            administrative infrastructure to operate the joint venture
            partner's company. In the short-term, this arrangement allows the
            Numanco Companies to better utilize its existing manpower and
            administrative support. The long-term goal is for this business to
            provide new service opportunities for the Numanco Companies. The
            operation and acquisition of the joint venture partner company will
            not adversely impact the Numanco Companies' results of operation or
            financial position.


2) Description of any services provided to PSO by the Numanco Companies during
the reporting period

       *     No services were provided to PSO during the reporting period by the
             Numanco Companies.


      3) Statement of any dividends or interest paid to PSO, both for the
reporting period and cumulatively, as a result of its equity interests in the
Numanco Companies


       *    No interest was paid to PSO during the reporting period or
            cumulatively.
<PAGE>

       *    No dividends were paid to PSO during the reporting period or
            cumulatively.

       *    As a Limited Liability Company, all of the Numanco Companies' 
            earnings must be distributed to its members. In 1997, PSO accrued 
            $1,874,348 equity earnings associated with its investment in the 
            Numanco Companies.



      4) Statement regarding the nature and consequences of any event of default
under the member agreement occurring during the period

in turn, Nuvest's control over all other Numanco Companies, to one or more of
the following: (A) electing a new Manager for one or all of the Numanco
Companies, (B) electing new officers for Numanco Inc., (C) overseeing the
development of a restructured operating plan for the Numanco Companies, and/or
(D) liquidating and dissolving the Numanco Companies; provided further, in the
event Monika is entitled to purchase the Interest of PSO pursuant to one of the
provisions of Section 8.4, and Monika provides notice to PSO pursuant to Section
8.5(a) that she is exercising such right, then PSO shall refrain from exercising
its control pursuant to (A), (B), (C), and (D) above until such time as Monika's
right to purchase PSO's Interest lapses because of Monika's failure, for
whatever reason (as long as the reason is not due to any breach of duty by PSO),
to purchase PSO's Interest on the closing date described in Section 8.5(b) and
in accordance with the other terms described in Sections 8.5 and 8.6.

         8.4.  Buy-Sell.  Subject to the provisions of Sections 8.5 and 8.6:

                  (a) Upon the occurrence of the Buy-Sell Event set forth in
Section 7.1, Monika may purchase all (but not less than all) of PSO's Interest,
and if Monika chooses not to do so, PSO may purchase all (but not less than all)
of Monika's Interest. Monika shall have no right to require PSO to purchase her
Interest.

                  (b) Upon the occurrence of the Buy-Sell Event set forth in
Section 7.2, Monika may, at her option, either purchase all (but not less than
all) of PSO's Interest, or require PSO to purchase all (but not less than all)
of Monika's Interest. PSO shall have no right to purchase any of Monika's
Interest, should Monika choose not to exercise her rights under this Section
8.4(b).

                  (c) Upon the occurrence of one of the Buy-Sell Events set
forth in Sections 7.3, 7.4, 7.5, 7.6, or 7.7, PSO shall have the right to
purchase all (but not less than all) of Monika's Interest. Monika shall have no
right to purchase any of PSO's Interest or to require PSO to purchase her
Interest.

                  (d) Upon the occurrence of one of the Buy-Sell Events set
forth in Section 7.8, Monika may require PSO to purchase all of her Interest. If
Monika chooses not to do so, PSO may purchase not more than fifty percent (50%)
(but not less than 50%) of Monika's Interest, and, at PSO's option, PSO may
cause the Operating Agreements of the Numanco Companies, as applicable, to
convert any Interest retained by Monika in any Numanco Company to a non-voting
Interest.

                  (e) Upon the occurrence of the Buy-Sell Event set forth in
Section 7.9, PSO may purchase all (but not less than all) of Monika's Interest.
If PSO chooses not to do so, the parties will proceed to sell the Numanco
Companies as soon as is reasonably practicable, and the proceeds of such sale
shall be distributed between PSO and Monika in accordance with their respective
Interests.

                  (f) Upon the occurrence of the Buy-Sell Event set forth in
Section 7.10, Monika may purchase all (but not less than all) of PSO's Interest.
If Monika chooses not to do so, the parties will proceed to sell the Numanco
Companies as soon as is reasonably practicable, and the proceeds of such sale
shall be distributed between PSO and Monika in accordance with their respective
Interests.

                  (g) Upon the occurrence of a Buy-Sell Event set forth is
Section 7.11, PSO shall, at Monika's request, purchase all (but not less than
all) of Monika's Interest, [and if Monika chooses not to do so, PSO may purchase
all, but not less than all, of Monika's Interest].

         8.5.     Purchase Procedures.  Any right to compel the purchase or sale
of an Interest under Section 8.4 may be exercised only pursuant to the following
procedures and terms:

                  (a) The party entitled to exercise the right (the "Exercising
Party") shall provide the other party with notice of the Exercising Party's
intent to purchase the Interest of the other party (or the Exercising Party's
intent to require the other party to purchase the Exercising Party's Interest,
as the case may be) within thirty (30) days after the occurrence of the event
giving rise to the right.

                  (b) The closing of Monika's purchase of PSO's Interest shall
occur on the one hundred twentieth (120th) day following PSO's receipt of
Monika's notice described in Section 8.5(a), at the corporate offices of PSO in
Tulsa, Oklahoma; provided, in no event shall PSO be obligated to sell its
Interest to Monika unless and until PSO is released of all liability under its
guaranty and any other agreement by which it is or has become responsible for
the payment of all or a part of the Indebtedness.

                  (c) In the event that notice pursuant to Section 8.5(a) will
result in the purchase by PSO of all or a part of Monika's Interest
(irrespective of whether PSO or Monika is the Exercising Party), PSO shall, as
soon as is reasonably practicable after such notice is given, file an
application with the SEC for approval to acquire such Interest and pursue such
application in good faith and with reasonable diligence. The closing of PSO's
purchase of Monika's Interest shall occur at PSO's corporate offices in Tulsa on
the thirtieth (30th) day following PSO's receipt of an order from the SEC
approving the purchase; provided, if the SEC denies PSO's application or fails
for any reason to rule on the application within ninety (90) days after such
notice is given pursuant to Section 8.5(a), then:

                           (i) if PSO is the Exercising Party, PSO's purchase
rights shall lapse with respect to the event giving right to such purchase 
right; and

                           (ii) if Monika is the Exercising Party, the parties
shall proceed to sell the Numanco Companies as soon as is reasonably 
practicable, and the proceeds of such sale shall be distributed between PSO and
Monika as follows:

                                    (A)     Monika shall receive all of the 
proceeds of such sale until she has received an amount equal to the Purchase 
Price for her Interest that would otherwise have been payable to Monika pursuant
to Section 8.6, plus simple interest on such amount at a varying rate per annum
equal to the Prime Rate (as defined in Section 8.6(e)), plus one percent (1%), 
accrued during a period commencing on the date that is 120 days after the date 
of the Buy-Sell Event and ending on the date Monika receives payment under this
Section 8.5(c)(ii)(A), and.

                                    (B) The remainder of such proceeds, if any,
shall be paid to PSO; provided further, if such SEC approval is obtained at any
time prior to the consummation of the sale of the Numanco Companies, the Numanco
Companies shall not be sold and PSO and Monika shall proceed with the closing of
the sale of Monika's Interest to PSO on the thirtieth (30th) day after receipt 
of the SEC order, at the Purchase Price, plus simple interest on such amount 
calculated in accordance with Section 8.5(c)(ii)(A).

         8.6. Purchase Price Calculation. The Members shall use their best
efforts to determine the value of each Member's Interest, as of the first day of
each calendar quarter (the "Agreed Value"). The Agreed Value shall not be
effective unless it is reduced to writing and signed by all Members. The
purchase price to be paid for the selling Member's Interest purchase pursuant to
Section 8.4 (the "Purchase Price") shall be the most recently determined Agreed
Value multiplied by the ratio the selling Member's Interest bears to the total
Interests of all Members; provided, if the Members cannot unanimously agree on
the Agreed Value at the quarterly meeting, or if the Agreed Value was not signed
by all Members, or if no Agreed Value was determined within a period of three
(3) months prior to the date of occurrence of the Buy-Sell Event, then the
Purchase Price of the Interest being purchased and sold shall be calculated as
follows:

                  (a) For each Numanco Company, an estimate shall be made of the
gross proceeds expected to be received from each service "Contract" (defined as
any written or oral agreement or understanding pursuant to which the Numanco
Company has the right to render a service to any Person who is not an Affiliate
of the Numanco Company) in effect as of the ninetieth (90th) day following the
date of the Buy-Sell Event (the "Valuation Date").

                  (b) There shall be added to or subtracted from the gross
proceeds determined pursuant to Section 8.6(a) any proceeds attributable to any
additions or deletions to the Contract effected through the Valuation Date.

                  (c) With respect to each Contract, an estimate shall be made
of all "Direct Costs" (defined as the sum of the gross payroll expense, the
pass-through per diem expense, the employer payroll tax expense, and other
direct costs required in order to perform the Contract) the Numanco Company will
be required to incur in order to perform the work specified under the Contract.

                  (d) With respect to each Contract, the net proceeds of the
Contract shall be determined by subtracting the Direct Costs estimated pursuant
to Section 8.6(c) from the gross proceeds estimated pursuant to Sections 8.6(a)
and (b).

                  (e) The present value of the net proceeds of each Contract, as
calculated pursuant to Section 8.6(d), shall be determined, using as a discount
rate the "Prime Rate", as published in the Wall Street Journal ("WSJ") on the
Valuation Date (or, if WSJ is not published on the Valuation Date, on the next
date in which the WSJ is published), plus one percent (1%).

                  (f) The present value of each Contract, as determined pursuant
to Section 8.6(e), shall be added together.

                  (g) The sum calculated pursuant to Section 8.6(f) shall be
multiplied by the ratio the Interest being purchased and sold bears to the total
Interests of all Members.

                  (h) The Purchase Price shall be determined by adding the
amount calculated pursuant to Section 8.6(g) to the capital account balance
(including undistributed earnings) in each Numanco Company, as of the Valuation
Date, of the Member whose Interest is being purchased and sold.

         8.7 Covenant Not to Compete. The Members acknowledge that any sale
which occurs pursuant to Section 8.4 shall involve the sale of the good will of
the business of the Numanco Companies. The parties agree that the Purchase Price
(whether pursuant to the Agreed Value or the formula set forth in Sections
8.6(a) through (h)) includes consideration for the good will of the business.
Therefore, the selling Member agrees for and in consideration of the Purchase
Price, to execute a Noncompetition Agreement in favor of the Company in the form
attached hereto as Exhibit E.

         8.8 Additional Purchase/Sale Rights. Unless the parties otherwise agree
in writing, the Members shall have the following additional purchase and sale
rights:

                  (a) During the month of January in the year 2000, and during
the month of January of each year thereafter while this Agreement remains in
effect, either Member may request that the other Member purchase the requesting
Member's Interest. The date of any such request shall be referred to herein as
the "Request Date."

                  (b) If, within thirty (30) days after the Request Date, the
other Member declines the request or the Members are unable to agree upon a
purchase price for the requesting Member's Interest, the Members shall proceed
to sell the Numanco Companies as soon as is reasonably practicable at a sales
price both Members agree upon. However, if

                           (i) within sixty (60) days after the Request Date,
the Members do not reach agreement as to a sales price for the Numanco Companies
to a third party, or

                           (ii) the Members agree upon a sales price for the
Numanco Companies to a third party but a letter of intent for the sale of the 
Numanco Companies at such price is not signed within one-hundred eighty (180) 
days after the Request Date, then the parties shall follow the procedures 
described in Section 8.8(d).

                  (c) If, pursuant to a request made by a Member under Section
8.8(a), the Members do agree upon a purchase price for the requesting Member's
Interest, the Members shall have a period of one-hundred twenty (120) days after
the Request Date to enter into a definitive agreement between themselves for the
purchase and sale of the selling Member's Interest, which agreement shall
provide for the closing of such transaction to occur not later than one-hundred
eighty (180) days after the Request Date. However, if

                           (i)  within the 120-day period following the Request
Date, the Members do not enter into a definitive agreement between themselves 
for the purchase and sale of the selling Member's Interest, or

                           (ii) the Members enter into a definitive agreement
between themselves for the purchase and sale of the selling Member's Interest, 
but the closing of the sale of the selling Member's Interest does not, for any 
reason (including the failure of the SEC to approve the sale under the 
circumstances described in Section 8.8(e)), occur within the 180-day period 
following the Request Date, then the parties shall follow the procedures 
described in Section 8.8(d).

         (d) The parties shall have a period of thirty (30) days after the
occurrence of the final event applicable under Section 8.8(b)(i) or (ii), or the
final event applicable under Section 8.8(c)(i) or (ii), as the case may be, to
agree to continue operating the Numanco Companies under this Agreement, the
Operating Agreements, and the Manager's Agreement, but if the parties cannot
reach agreement to continue operations within such 30-day period, the parties
shall proceed to sell the Numanco Companies at the best sales price available in
the market. The proceeds of a sale effected pursuant to the preceding sentence
shall be distributed between the Members in accordance with the liquidation
provisions of the Operating Agreements of the Numanco Companies. Until the
closing of such sale, all such Operating Agreements, the Managers' Agreement,
and this Agreement shall remain in full force and effect.

         (e) If, pursuant to a request made by Monika under Section 8.8(a), PSO
agrees to purchase Monika's Interest for a mutually agreeable purchase price,
then (i) PSO shall, as soon as is reasonably practicable after reaching such
agreement, file an application with the SEC for approval to acquire such
Interest and pursue such application in good faith and with reasonable
diligence, and (ii) the definitive agreement for such purchase and sale shall
provide, as a condition precedent to PSO's obligation to purchase Monika's
Interest, that the SEC shall have issued an order, prior to the expiration of
the 180-day period specified in Section 8.8(c), approving PSO's acquisition of
the Interest.

9.       Notices.

         9.1. All notices required or given under this Agreement shall be in

service with next-day delivery requested; or (iii) five days after it is sent,

10.      Limitation of Members' Liability.

         10.1 Limitation of Members' Liability. Anything herein to the contrary
notwithstanding, except as otherwise expressly agreed in writing, no Member
shall be personally liable for any of the obligations created by this Agreement
or for any debts, liabilities, or obligations of any of the Numanco Companies,

creditors of the Companies, beyond the Member's Capital Account, as defined in
the Operating Agreement for each Numanco Company, together with the Member's

11.      General.

         11.1. Entire Agreement. This Agreement constitutes the whole and entire
agreement between the parties pertaining to the subject matter hereof, and
supersedes all prior agreements or understandings. This Agreement may not be
modified except by an instrument in writing signed by all parties.

         11.2. Governing Law. The validity, construction and enforcement of, and
the remedies under, this Agreement shall be governed in accordance with the laws

         11.3. Jurisdiction and Venue. The parties to this Agreement agree that
jurisdiction and venue of any action brought to enforce, or to construe or
determine the validity of, any term or provision contained in this agreement
shall properly lie in the District Court of Tulsa County, Oklahoma, or the

jurisdiction and venue are merely permissive; jurisdiction and venue shall also
continue to lie in any court where jurisdiction and venue would otherwise be
proper. The parties further agree that the mailing by certified or registered

statute or rule of court.

         11.4. Binding Effect; 1935 Act Compliance; Assignment. This Agreement
shall inure to the benefit of and be binding upon the parties hereto and their

this Agreement to its parent corporation, Central and South West Corporation, or
any direct or indirect subsidiary of such parent.

         11.5. Injunctive Relief. Each of the parties hereto hereby acknowledges
that in the event of a breach by any of them of any material provision of this

the parties therefore agrees that in the event of a breach of any material
provision of this Agreement the aggrieved party may elect to institute and
prosecute proceedings in any court of competent jurisdiction to enforce specific
performance or to enjoin the continuing breach of such provision, as well as to
obtain damages for breach of this Agreement. By seeking or obtaining any such
relief, the aggrieved party will not be precluded from seeking or obtaining any
other relief to which it may be entitled.

         11.6. Waiver. Except as otherwise provided in this Agreement, any
failure of any of the parties to comply with any obligation, covenant, agreement
or condition herein may be waived by the parties entitled to the benefits
thereof only by a written instrument signed by the party granting such waiver,
but such waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

         11.7. Pronouns and Plurals. Whenever the context may require, any
pronoun used in this Agreement shall include the corresponding masculine,
feminine or neuter forms, and the singular form of nouns, pronouns and verbs

her own expenses incurred in connection with negotiation, preparation and
execution of this Agreement and the transactions contemplated herein.

the Company transferred in accordance with Article XI will succeed to the
Capital Account relating to the Member transferring such interest. However, if

of a Member, the Manager shall distribute to the Member on or before April 15 of
each year an amount equal to the Member's Tax Distribution. All other
distributions from Cash Available for Distribution shall be determined by the

value of such property. Except as otherwise provided herein, distributions shall
be allocated between the Members in accordance with their respective Unit
ownership.

         5.02 Allocation of Tax Items. All Tax Items shall be allocated between
the Members in accordance with their respective Unit ownership.

         5.03     Regulatory Allocations.  The following special allocations 
shall be made for each Company taxable year in the following order:

                  (a) Minimum Gain Chargeback. If there is a net decrease in
Company Minimum Gain (other than Minimum Gain attributable to Member Nonrecourse
Debt or net decreases in Minimum Gain attributable to transactions subject to
the exceptions contained in Reg. ss. 1.704-2(f)(2)-(5)) during any Company
taxable year, each Member shall be specially allocated items of Company income
and gain for such year equal to such Member's share of the net decrease in
Company Minimum Gain during that year. Each Member's share of the net decrease
in Company Minimum Gain shall be determined in accordance with Reg. ss.
1.704-2(g)(2). This Section 5.03(a) is intended to comply with the minimum gain
chargeback requirement in Reg. ss. 1.704-2(f) and shall be interpreted
consistently therewith.

                  (b)      Member Nonrecourse Debt Minimum Gain Chargeback.
If there is a net decrease in Member Minimum Gain attributable to a Member
Nonrecourse Debt during any Company taxable year, each Member with a share of
such Member Minimum Gain attributable to a Member Nonrecourse Debt determined in
accordance with Reg. ss. 1.704-2(i)(5), shall be specially allocated items of
Company income and gain for such year (and, if necessary, subsequent years)
equal to such Member's share of the net decrease in Member Minimum Gain during
such year. Each Member's share of the net decrease in Member Minimum Gain
attributable to a Member Nonrecourse Debt shall be determined in a manner
consistent with Reg. ss. 1.704-2(g)(2). This subsection is intended to comply
with the minimum gain chargeback requirement in Reg. ss. 1.704-2(i)(4)
pertaining to Member Nonrecourse Debt and shall be interpreted consistently
therewith.

                  (c) Gross Income Allocation. In the event any Member has a
Capital Account deficit at the end of any Company taxable year which is in
excess of the sum of (i) the amount such Member is obligated to restore, and
(ii) the amount such Member is deemed to be obligated to restore pursuant to the
penultimate sentence of Reg. ss. 1.704-2(g)(1), each such Member shall be
specially allocated items of Company income and gain in the amount of such
excess as quickly as possible, provided that an allocation pursuant to this
Section 5.03(c) shall be made only if and to the extent that any such Member
would have a deficit Capital Account in excess of such sum after all other
allocations provided for in this Article V have been tentatively made as if this
Section 5.03(c) hereof and Section 5.03(d) were not in the Agreement.

                  (d) Qualified Income Offset. In the event any Member
unexpectedly receives any adjustments, allocations or distributions described in
Reg. ss. 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain
shall be specially allocated to each such Member in an amount and manner
sufficient to eliminate, to the extent required by the Treasury Regulations, the
Adjusted Capital Account Deficit of such Member as quickly as possible, provided
that an allocation pursuant to this Section 5.03(d) shall be made only if and to
the extent that any such Member would have an Adjusted Capital Account Deficit
after all other allocations provided for in this Article V have been tentatively
made as if this Section 5.03(d) were not in the Agreement.

                  (e) Nonrecourse Deductions. Nonrecourse Deductions for any
taxable year or other periods shall be allocated among the Members in proportion
to their respective Capital Contributions.

                  (f) Member Loan Nonrecourse Deductions. Any Member Loan
Nonrecourse Deductions for any fiscal year or other period shall be allocated to
the Members who bear the risk of loss with respect to the loan to which such
Member Loan Nonrecourse Deductions are attributable in accordance with Reg. ss.
1.704-2(i).

                  (g) Section 754 Adjustments. To the extent an adjustment to
the adjusted tax basis of any Company Property pursuant to Section 734(b) or
Section 743(b) of the Code is required, pursuant to Reg. ss.
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis) and such gain or loss shall be specially
allocated to the Member(s) in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such section of the
Regulations.

         5.04 Curative Allocations. The allocations set forth in Section 5.03,
hereof (the "Regulatory Allocations") are intended to comply with certain
requirements of the Regulations. It is the intent of the Members that, to the
extent possible, all Regulatory Allocations shall be offset either with other
Regulatory Allocations or with special allocations of other Tax Items pursuant
to this Article V. Therefore, notwithstanding any other provision of this
Article V (other than the Regulatory Allocations), the Manager shall make such
offsetting special allocations of Tax Items in whatever manner he determines
appropriate so that, after such offsetting allocations are made, each Member's
Capital Account balance is, to the extent possible, equal to the Capital Account
balance such Member would have had if the Regulatory Allocations were not part
of the Agreement and all Tax Items were allocated pursuant to Section 5.03. In
exercising his discretion under this Section 5.04, the Manager shall take into
account future Regulatory Allocations under Sections 5.03(a) and (b) that,
although not yet made, are likely to offset other Regulatory Allocations
previously made under Sections 5.03(e) and (f).

         5.05. Special Allocation of Gain or Loss on Contributed Property. Under
Regulations prescribed by the Secretary of the Treasury pursuant to Section
704(c) of the Code, Tax Items with respect to property contributed to the
Company by a Member shall be shared among Members so as to take account of the
variation between the basis of the property to the Company and its fair market
value at the time of contribution. The Manager shall have the power to make such

Company's expense, on behalf of any Indemnities against any liability that may
be asserted against or expense that may be incurred by an Indemnitee in

Company Minimum Gain (other than Minimum Gain attributable to Member Nonrecourse
Debt or net decreases in Minimum Gain attributable to transactions subject to
the exceptions contained in Reg. ss. 1.704-2(f)(2)-(5)) during any Company

Company Minimum Gain during that year. Each Member's share of the net decrease
in Company Minimum Gain shall be determined in accordance with Reg. ss.

chargeback requirement in Reg. ss. 1.704-2(f) and shall be interpreted
consistently therewith.

                  (b) Member Nonrecourse Debt Minimum Gain Chargeback.

Nonrecourse Debt during any Company taxable year, each Member with a share of
such Member Minimum Gain attributable to a Member Nonrecourse Debt determined in

Company income and gain for such year (and, if necessary, subsequent years)

such year. Each Member's share of the net decrease in Member Minimum Gain
attributable to a Member Nonrecourse Debt shall be determined in a manner
consistent with Reg. ss. 1.704-2(g)(2). This subsection is intended to comply
with the minimum gain chargeback requirement in Reg. ss. 1.704-2(i)(4)
pertaining to Member Nonrecourse Debt and shall be interpreted consistently
therewith.

Capital Account deficit at the end of any Company taxable year which is in
excess of the sum of (i) the amount such Member is obligated to restore, and
(ii) the amount such Member is deemed to be obligated to restore pursuant to the
penultimate sentence of Reg. ss. 1.704-2(g)(1), each such Member shall be
specially allocated items of Company income and gain in the amount of such
excess as quickly as possible, provided that an allocation pursuant to this
Section 5.03(c) shall be made only if and to the extent that any such Member
would have a deficit Capital Account in excess of such sum after all other
allocations provided for in this Article V have been tentatively made as if this
Section 5.03(c) hereof and Section 5.03(d) were not in the Agreement.

                  (d) Qualified Income Offset. In the event any Member
unexpectedly receives any adjustments, allocations or distributions described in
Reg. ss. 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain
shall be specially allocated to each such Member in an amount and manner
sufficient to eliminate, to the extent required by the Treasury Regulations, the
Adjusted Capital Account Deficit of such Member as quickly as possible, provided
that an allocation pursuant to this Section 5.03(d) shall be made only if and to
the extent that any such Member would have an Adjusted Capital Account Deficit
after all other allocations provided for in this Article V have been tentatively
made as if this Section 5.03(d) were not in the Agreement.

                  (e) Nonrecourse Deductions. Nonrecourse Deductions for any
taxable year or other periods shall be allocated among the Members in proportion
to their respective Capital Contributions.

                  (f) Member Loan Nonrecourse Deductions. Any Member Loan
Nonrecourse Deductions for any fiscal year or other period shall be allocated to
the Members who bear the risk of loss with respect to the loan to which such
Member Loan Nonrecourse Deductions are attributable in accordance with Reg. ss.
1.704-2(i).

                  (g) Section 754 Adjustments. To the extent an adjustment to
the adjusted tax basis of any Company Property pursuant to Section 734(b) or
Section 743(b) of the Code is required, pursuant to Reg. ss.
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis) and such gain or loss shall be specially
allocated to the Member(s) in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such section of the
Regulations.

         5.04 Curative Allocations. The allocations set forth in Section 5.03,
hereof (the "Regulatory Allocations") are intended to comply with certain
requirements of the Regulations. It is the intent of the Members that, to the
extent possible, all Regulatory Allocations shall be offset either with other
Regulatory Allocations or with special allocations of other Tax Items pursuant
to this Article V. Therefore, notwithstanding any other provision of this
Article V (other than the Regulatory Allocations), the Manager shall make such
offsetting special allocations of Tax Items in whatever manner he determines
appropriate so that, after such offsetting allocations are made, each Member's
Capital Account balance is, to the extent possible, equal to the Capital Account
balance such Member would have had if the Regulatory Allocations were not part
of the Agreement and all Tax Items were allocated pursuant to Section 5.03. In
exercising his discretion under this Section 5.04, the Manager shall take into
account future Regulatory Allocations under Sections 5.03(a) and (b) that,
although not yet made, are likely to offset other Regulatory Allocations
previously made under Sections 5.03(e) and (f).

         5.05. Special Allocation of Gain or Loss on Contributed Property. Under
Regulations prescribed by the Secretary of the Treasury pursuant to Section
704(c) of the Code, Tax Items with respect to property contributed to the
Company by a Member shall be shared among Members so as to take account of the
variation between the basis of the property to the Company and its fair market
value at the time of contribution. The Manager shall have the power to make such
elections, adopt such conventions, and allocate Tax Items as he deems
appropriate to comply with Section 704(c) of the Code and any Regulations
promulgated thereunder and to preserve, to the extent possible, uniformity of
the Members' interests in the profits and capital of the Company. Any Tax Items
allocated under this Section 5.05 shall not be debited or credited to Capital
Accounts to the extent that item is already taken into account (upon formation
or otherwise) in determining a Member's Capital Account.

         5.06. Change or Transfer of Interests in Profits and Capital. Upon the
transfer of an interest in the profits and capital of the Company in accordance
with Article XI, Tax Items attributable to the transferred interest shall, for
federal income tax purposes, be allocated between the transferor and the
transferee of such interest based on the number of months that each such Person
was the owner of the interest, in a manner determined by the Manager to be
consistent with the requirements of Section 706 of the Code and Regulations or
rulings promulgated thereunder.

         5.07. Deemed Income or Gain. If, and to the extent that, any Member is
deemed to recognize income or gain as a result of any transaction between the
Member and the Company pursuant to Sections 482, 483, 1272-1274, or 7872 of the
Code, or any similar provision now or hereafter in effect, any corresponding
resulting loss or deduction of the Company shall be allocated to the Member who
was allocated such income or gain.

         5.08. Recapture Items. Any portion of any income or gain attributable
to the sale or other disposition of any depreciable Company Property required to
be recaptured as ordinary income shall, to the maximum extent possible in
accordance with Section 704 of the Code and the Regulations thereunder, be
allocated among the Members for tax purposes in the same ratio as the deductions
giving rise to such recapture were allocated. Any recapture of tax credit shall
be allocated among the Members in accordance with Reg. ss. 1.704-1(b)(4)(ii).

         6.04. Outside Activities. The Members and Manager and their respective

to prohibit the Members, the Manager or their respective Affiliates from

of loyalty to the Company, (ii) for acts or omissions not in good faith or which

notwithstanding, except as otherwise expressly agreed in writing, a Member shall
not be personally liable for any debts, liabilities, or obligations of the
Company, whether to the Company, to any of the other Members, or to creditors of

indemnify and hold harmless the Manager, all Members, their respective
Affiliates, and the employees and agents of the Company (each, an "Indemnitee")
from and against any and all losses, claims, demands, costs, damages,
liabilities, joint and several, expenses of any nature (including attorneys'
fees and disbursements), judgments, fines, settlements, penalties and other
expenses actually and reasonably incurred by the Indemnitee in connection with
any and all claims, demands, actions, suits, or proceedings, civil, criminal,
administrative or investigative, in which the Indemnitee may be involved, or
threatened to be involved, as a party or otherwise, by reason of the fact that
the Indemnitee is or was a Manager or Member of the Company or is or was an
employee or agent of the Company, including Affiliates of the foregoing, arising
out of or incidental to the business of the Company, provided, (i) the
Indemnitee's conduct did not constitute willful misconduct or recklessness, (ii)
the action is not based on breach of this Agreement, (iii) the Indemnitee acted
in good faith and in a manner he or it reasonably believed to be in, or not
opposed to, the best interests of the Company and within the scope of such
Indemnitee's authority and (iv) with respect to a criminal action or proceeding,
the Indemnitee had no reasonable cause to believe its conduct was unlawful. The
termination of any action, suit, or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere, or its equivalent, shall not, in
and of itself, create a presumption or otherwise constitute evidence that the
Indemnitee acted in a manner contrary to that specified above.

                  (b) Expenses incurred by an Indemnitee in defending any claim,
demand, action, suit or proceeding subject to this Section 7.03 may, from time
to time, be advanced by the Company prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Company of an
undertaking by or on behalf of the Indemnitee to repay such amount if it shall
ultimately be determined that such person is not entitled to be indemnified as
authorized in this Section 7.03.

                  (c) Indemnification provided by this Section 7.03 shall be in
addition to any other rights to which the Indemnitee may be entitled under any
agreement, vote of the Members, as a matter of law or equity, or otherwise, and
shall inure to the benefit of the successors, assignees, heirs, personal
representatives and administrators of the Indemnitee.

                  (d) The Company may purchase and maintain insurance, at the
Company's expense, on behalf of any Indemnities against any liability that may
be asserted against or expense that may be incurred by an Indemnitee in
connection with the activities of the Company regardless of whether the Company
would have the power to indemnify such Indemnitee against such liability under
the provisions of this Agreement.

shall have no right to require any information or account of the Company's
transactions or to inspect the Company's books and records, tax return
information, or any other information, documents, or other data associated with

treat such assigning Member as the absolute owner thereof in all respects, and
(B) shall incur no liability for distributions or for allocations of income,

transferred in accordance with this Article XI shall not become a Substitute
Member unless and until admitted as a Substitute Member pursuant to Article XII.
Any such transferee who does not become a Substitute Member shall have no right

of profits or other compensation by way of income and the return of
contributions to which the transferring Member would otherwise be entitled at
the time said transferring Member would be entitled to receive the same.

         10.02.  Transfer of Interests by a Member.

                  (a) No interests in the profits and capital may be transferred

delivered to the Company a duly executed and acknowledged counterpart of the 
instrument of assignment and such instrument evidences the written acceptance by
the transferee of all of the terms and provisions of this Agreement and

and regulations; and (B) executed and delivered to the Company such other 
instruments as the Manager may reasonably deem necessary or desirable to effect
the assignment; and

                     (ii) The Company has received an opinion from counsel for
the assigning Member, in form and substance satisfactory to the Manager, that 
such transfer; (A) would not materially adversely affect the classification of 
the Company as a partnership for federal and (as applicable) state income tax 
purposes; and (B) would not violate applicable federal and state securities laws
or rules and regulations of the Securities and Exchange Commission, any state 
securities commission or any other governmental authority with jurisdiction over
the transfer.

                  (b) Without the consent of the Manager, no transfer of an
interest in the profits and capital of the Company may be made if such transfer,
when added to the total of all other transfers within the preceding 12 months,
would result in the Company being considered to have terminated within the
meaning of Section 708(b)(1)(B) of the Code.

                  (c) In no event shall any interest be transferred to a minor
(except in trust pursuant to the Uniform Transfers to Minors Act) or any
incompetent (except in trust).

become a Substitute Member with respect to the interest acquired, subject to the
conditions of and in the manner permitted under this Agreement. No transferee of
an interest shall become a Substitute Member with respect to the transferred

with respect to other previously acquired interests) unless and until all of the
following conditions are satisfied:

                  (i) The instrument of assignment sets forth the intentions of

Substitute Member in his place;

other requirements of this Agreement;

                  (iii) The transferee shall have paid all reasonable legal fees
and filing costs incurred by the Company in connection with his substitution as
a Member; and

                  (iv) The Members shall have unanimously approved such
substitution in writing, which approval may be granted or withheld by each
Member in its sole and absolute discretion and may be arbitrarily withheld, and
the books and records of the Company have been modified to reflect the
admission; provided, in the event Public Service Company of Oklahoma ("PSO")

and between ________________________ (the "Departing Member"), and Nuvest,

                  The Departing Member has been a Member of Nuvest and is
experienced in the business, management and operations of the Company.

                  Pursuant to that certain Member Agreement by and among the
Departing Member, the Company and others, the Departing Member sold all of its
interest in Nuvest for a Purchase Price (as defined in the Member Agreement)
that included compensation for the Departing Member's proportionate share of the
good will of the Company.

                  Recognizing the Departing Member's unique position in the
Company and the detriment to the Company were the Departing Member to directly
or indirectly compete with the Company, and in consideration for the mutual
covenants contained in the Member Agreement, the Departing Member has agreed to
refrain from directly or indirectly competing with the Company under the terms
and conditions contained herein.

                  Definitions.  The following terms, when used in this 
Agreement, shall have the meanings ascribed to them:

                  "Affiliate" shall mean (i) any Person that directly or
indirectly controls or is controlled by or is under common control with the
specified Person, (ii) any Person that is an executive officer of, general
partner in or trustee of, or serves in a similar capacity with respect to, the
specified Person or of which the specified Person is an executive officer,
general partner or trustee, or with respect to which the specified Person serves
in a similar capacity, and (iii) any Person that, directly or indirectly, is the
beneficial owner of 10% or more of any class of equity securities of the
specified Person or of which the specified Person is directly or indirectly the
owner of 10% or more of any class of equity securities.

                  "Person" shall mean any individual, partnership, corporation,
joint venture, trust, business trust, cooperative or association, and the heirs,
executors, administrators, legal representatives, successors and assigns of such
Person where the context so admits.

         3. Term. The term of this Agreement (the "Noncompetition Period") shall
commence on the date hereof and shall continue for a period of three (3) years.

         4. Covenant Not to Compete. The Departing Member covenants that during

the State of Oklahoma, the State of Pennsylvania, or within any state or foreign
country in which the Company or any of its Affiliates maintains an office or
conducts business, enter into, engage in, be employed by or consult with any
business in competition with the business of the Company or any of its
Affiliates.
         5. Nonsolicitation of Customers. The Departing Member covenants that

Affiliates, or in any way discourage such customers from doing business with the
Company or any of its Affiliates.

         6. Nonsolicitation of Employees. The Departing Member covenants that
during the Noncompetition Period he shall refrain from soliciting and shall not,
either directly or indirectly, solicit any employee of the Company or any of its

ownership by the Departing Member of not more than two percent (2%) of the
outstanding securities of any company whose stock is traded on a national
securities exchange or is quoted on NASDAQ.

         8. Equitable Relief. The Departing Member acknowledges that the
obligations to be observed by him are of a special and unique character, which
gives them a peculiar value, and the failure by him to observe such obligations
cannot be reasonably or adequately compensated in damages in an action at law;
and that a breach by him of any of the provisions contained in this Agreement
will cause the Company and its Affiliates irreparable injury and damage. The
Departing Member further acknowledges that he possesses unique skills,
knowledge, and ability and that competition by him in violation of this
Agreement or any other breach of the provisions of this Agreement would be
extremely detrimental to The Company and its Affiliates. The Departing Member

Manager from all Numanco affiliates, shall not exceed $20,833.00 per month.

         4.2 Reimbursement of Expenses. Company agrees to reimburse the ordinary
and necessary expenses incurred by Manager in the performance of Managers'
duties and responsibilities hereunder. An itemization of such reimbursed
expenses shall be provided to each of the Members, along with the other monthly
financial reports as prepared by the Manager.

         4.3      Indemnification.

                  A. To the maximum extent permitted by law, the Numanco
Companies shall indemnify and hold harmless the Manager and his affiliates
(each, an "Indemnitee") from and against any and all losses, claims, demands,
costs, damages, liabilities, joint and several, expenses of any nature
(including attorneys' fees and disbursements), judgments, fines, settlements,
penalties and other expenses actually and reasonably incurred by the Indemnitee
in connection with any and all claims, demands, actions, suits, or proceedings,
civil, criminal, administrative or investigative, in which the Indemnitee may be
involved, or threatened to be involved, as a party or otherwise, by reason of
the fact that the Indemnitee is or was a Manager of the Numanco Companies or is
or was an agent of the Numanco Companies, including affiliates of the foregoing,
arising out of or incidental to the business of the Numanco Companies, provided,
(i) the Indemnitee's conduct did not constitute willful misconduct or
recklessness, (ii) the action is not based on breach of this Agreement, (iii)
the Indemnitee acted in good faith and in a manner he or it reasonably believed
to be in, or not opposed to, the best interests of the Numanco Companies and
within the scope of such Indemnitee's authority and (iv) with respect to a
criminal action or proceeding, the Indemnitee had no reasonable cause to believe
its conduct was unlawful. The termination of any action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere, or
its equivalent, shall not, in and of itself, create a presumption or otherwise
constitute evidence that the Indemnitee acted in a manner contrary to that
specified above.
                  B. Expenses incurred by an Indemnitee in defending any claim,
demand, action, suit or proceeding subject to this Section 4.3 may, from time to
time, be advanced by the Numanco Companies prior to the final disposition of
such claim, demand, action, suit or proceeding upon receipt by the Numanco
Companies of an undertaking by or on behalf of the Indemnitee to repay such
amount if it shall ultimately be determined that such person is not entitled to
be indemnified as authorized in this Section 4.3.

                  C. Indemnification provided by this Section 4.3 shall be in
addition to any other rights to which the Indemnitee may be entitled under any
agreement, vote of the Members, as a matter of law or equity, or otherwise, and
shall inure to the benefit of the successors, assignees, heirs, personal
representatives and administrators of the Indemnitee.

Section 5.        EVENTS OF TERMINATION; REMEDIES.

         5.1 Events of Termination. Each of the following events shall be an
"Event of Termination":

                           A. Death or disability of Manager. For the purposes 
of this Agreement, "disability" shall mean any physical or mental condition 
which would keep Richard H. Smith from performing his duties as Manager for a 
continuous period of six months.

                           B. If this Agreement is extended beyond 12/31/99, the

lines of credit necessary to supply the sources of funds budgeted in the most 
recently approved Business Plan (to the extent the same cannot be supplied out 
of current operations); or

                                    (2) PSO shall fail to approve a proposed
amendment to the most recently approved Business Plan, if such proposed 
amendment would require PSO to guarantee a line of credit necessary to supply 
the sources of funds budgeted in such proposed amendment (to the extent the same
cannot be supplied out of current operations), so long as (i) such proposed 
amendment is consistent with the lines of business described in the most 
recently approved Business Plan, and (ii) there has not been a material adverse
change in any such lines of business or in any of the other assumptions 
underlying such Business Plan; or

                                    (3)  All of the following shall occur:

                                            (i) both of the current 
representatives of PSO (or the representatives of any affiliate of PSO) who are
assigned the primary responsibility for monitoring PSO's investment in the 
Numanco Companies and are serving as the principal contact between PSO and the 
Manager cease, for any reason, to serve in such capacity;

                                            (ii) the person or persons appointed
by PSO to replace such representatives, after serving in such capacity for a 
period of at least 90 days, are, despite the good faith efforts of such 
replacements and the Manager, unsatisfactory to the Manager; and

                                            (iii) the person or persons 
appointed by PSO, at the request of the Manager, to replace the persons 
described in (ii), after serving in such capacity for a period of at least 90 
days, are, despite the good faith efforts of such replacements and the Manager,
unsatisfactory to the Manager; provided, this Section 5.1C(3) shall not apply if
the person or persons appointed by PSO to replace the persons described in (ii)
is one or both of the current representatives of PSO (or its affiliate) 
described in (i).

                           D. The Numanco Companies may elect to terminate this
Agreement upon the following conditions:

                                    (1) Any Numanco Company shall default in the
payment when due of any principal or interest on any Indebtedness, as defined in
the Member Agreement between the Members, or shall default under or fail to 
perform or observe any material term, covenant or agreement contained in any 
material agreement, document or instrument to which it is a party or to which it
or its assets is bound, including any obligation for borrowed money or for the 
purchase price of property, and such default or failure to perform shall 
continue and remain unwaived by the obligee for more than 15 days or any 
applicable period of grace therein specified, whichever is longer, except where
the Company is in good faith and through appropriate proceedings contesting such
default or failure to perform.

                                    (2) Any covenant, representation or warranty
made herein or in connection with the transactions contemplated in this 
Agreement or in the Member Agreement shall be breached or shall prove to have 
been false or incorrect on the date as of which made resulting in a material 
adverse effect on the Company and such false or incorrect representation or 
warranty shall not have been remedied within fifteen (15) days after written 
notice thereof shall have been given to the Company.

                                    (3) Any Numanco Company shall make an 
assignment for the benefit of creditors, or shall admit in writing its inability
to pay its debts as they become due, or an order for relief is entered against 
the Company under any bankruptcy laws or the Company shall file any petition or
answer seeking for itself any reorganization, arrangement, composition, 
readjustment, dissolution or similar relief under any present or future statute,
law or regulation, or shall file an answer admitting the material allegations of

consent to the acquiesce in the appointment of any trustee, receiver or 
liquidator of the Company of all or any substantial part of the properties of 
the Company.

                                    (4) Manager shall, subject to the right to 
cure set forth in Section 5.2 hereof:

                                            (i) make an assignment for the 
benefit of his creditors or file for the protection under the bankruptcy laws or
become the subject of an involuntary petition under such laws;

                                            (ii) breach his duty of loyalty to 
the Company or any obligation under this Agreement; or

                                            (iii) enter into any transaction 
from which Manager derived an improper personal benefit to the detriment of a 
Numanco Company.

                           E. The Members unanimously elect to sell the Numanco
Companies (including a sale of substantially all of the assets of such 
companies) to a third party.

                           F. PSO, in its capacity as a Member, fails to renew 
and extend this Management Agreement with Richard H. Smith, or any extension 
thereof.

                           G. If (a) the FMV Net Worth (as defined in the Member
Agreement) falls to zero or below, (b) the Members and the Manager fail to reach
agreement on a new or revised Business Plan within thirty (30) days after PSO 
has made a request for same, (c) PSO provides notice to Monika that it desires 
to invoke the provisions of Section 7.1 of the Member Agreement, (d) Monika 
declines to purchase PSO's Interest pursuant to Section 8.4(a) of the Member 
Agreement, and (e) PSO provides notice to Monika that it intends to purchase 
Monika's Interest pursuant to Section 8.4(a) of the Member Agreement.

                           H. If Monika dies, becomes disabled (such that she 
cannot perform her duties as a Member for a period of six continuous months), or
files for protection under the bankruptcy laws, or with respect to any Numanco 
Company, there occurs any other event that, under the laws of the State of 
Oklahoma, would result in the dissolution of the Numanco Company (other than the
event described in Section 7.10 of the Member Agreement); provided, none of the
foregoing events described in this Section 5.1H relating to Monika shall result
in a termination of this Agreement as long as Richard Smith acquires or succeeds
to all of Monika's interest in Nuvest and Smith either (i) acquires or succeeds
to all of Monika's interest in Nuvest and becomes a Substitute Member of Nuvest
in accordance with the Nuvest Operating Agreement, or (ii) becomes trustee of a
trust that acquires or succeeds to all of Monika's interest in Nuvest and, in 
his capacity as such trustee, becomes a Substitute Member of Nuvest (provided, 
it is agreed that if for any reason Smith ceases to serve as the trustee of such
trust, the interest in Nuvest held by the trust shall automatically covert to an
economic interest having no voting rights), or (iii) acquires or succeeds to all
of Monika's interest in Nuvest through any combination of (i) or (ii).

                           I. If PSO involuntarily withdraws from Nuvest as a 
result of requirements imposed by regulatory authorities having jurisdiction 
over PSO.

         5.2 Curative Action. Upon written notice from a Numanco Company or a
Member alleging that an event described in Section 5.1 D.4 has occurred which
may lead to an Event of Termination, Manager shall have 30 days from the receipt
thereof to cure such event or otherwise take such action as may be necessary to
correct such action. If the Manager successfully cures or corrects such event,
then there shall be no Event of Termination.

         5.3 Remedies. In the event there is an Event of Termination (which is
not cured or rectified pursuant to Section 5.2 above), then this Agreement shall
be terminated upon the occurrence of such event or at the end of the curative
period, if any, relating to such event. Provided, however, if the Event of
Termination also constitutes a Buy-Sell Event as set forth in the Members'
Agreement, and pursuant to the rights set forth therein Monika (as defined in
the Member Agreement) elects to buy all of the Member's Interest (as defined in
the Member Agreement) of PSO or its successor, then this Management Agreement
shall continue as though no Event of Termination has occurred until such time as
Monika's right to purchase PSO's Interest lapses because of Monika's failure,
for whatever reason (as long as the reason is not due to any breach of duty by
PSO), to purchase PSO's Interest on the closing date described in Section 8.5(b)
of the Member Agreement and in accordance with the other terms described in
Sections 8.5 and 8.6 of the Member Agreement.

         5.4 Limitation of Manager's Liability. Although Manager has the duty
and authority "to cause" various activities to occur during his consulting with
the Numanco Companies, the parties agree that Manager shall use reasonable
efforts to accomplish these tasks and his various duties, but he is not
guaranteeing any activity or the performance of the Numanco Companies. The
Manager shall not be liable to the Numanco Companies for monetary damages for
breach of fiduciary duty as a Manager; provided, however, that nothing contained
herein shall eliminate or limit the liability of the Manager (i) for any breach
of the Manager's duty of loyalty to the Numanco Companies, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law and, (iii) for any transaction from which the Manager
derived an improper personal benefit.

         5.5 Payment of Deferred Fee. The parties acknowledge and agree that
Manager has heretofore performed services for the benefit of the Numanco
Companies and their affiliates which entitle the Manager to a fee of $250,000
(in addition to the fees provided for in Section 4.1). However, the parties
agree that the Numanco Companies may use their financial resources as working
capital for the growth of the Numanco Companies and defer the payment of the
$250,000 payable to the Manager under this Section 5.5 until such time as there
shall have occurred a Buy-Sell Event that results in (i) the sale by Monika
Smith of her Interest (as defined in the Member Agreement) to PSO, or (ii) the
sale of any one of the Numanco Companies to any Person (as defined in the Member
Agreement), in which event the Numanco Companies shall pay the $250,000 to
Richard H. Smith, his heirs, successors or assigns, on the date of the closing
of the sale described in (i) or (ii) above; provided, the Manager agrees that
the Numanco Companies' obligation to pay the $250,000 under this Section 5.5
shall be subordinated to all indebtedness owed by the Numanco Companies to any
Person; and provided further, if the proceeds received by Monika Smith pursuant
to a sale described in (i) is less than the aggregate balance of the capital
account (including undistributed earnings) in the Numanco Companies as of the
date of the closing of the sale (the "Capital Account Balance") of Monika Smith,
or, in the case of a sale pursuant to (ii), if the sale proceeds are less than
the aggregate of the Capital Account Balances of the Members, the $250,000
payment to Manager under this Section 5.5 shall be reduced pari passu. By way of
illustration, if the Members' proceeds from a sale pursuant to (ii) equal only
60% of the aggregate of their Capital Account Balances, the Manager shall
receive only 60% of the $250,000 payment. In addition to any right of set off
the Numanco Companies may have by law, in the event the sale under (i) or (ii)
above results from one of the Buy-Sell Events described in Section 7.7 of the
Member Agreement, the Company, in making the payment to the Manager under this
Section 5.5, shall have the right to deduct the actual compensatory damages, if
any, the Company may have incurred as a result of any breach by the Manager of
any of his obligations described in Section 5.4 of this Agreement.

         5.6 Sale; Balance of Manager's Fees. If this Agreement should be
terminated pursant to Section 5.lI hereof, and Monika Smith's share of the net
proceeds from any sale of the Numanco Companies that occurs pursuant to Section
8.4(f) of the Member Agreement is less than the compensation that would have
been payable to the Manager under this Agreement for the remainder of the term,
then the Manager shall be paid at the closing of the sale, $20,833/month for
every month from the date of termination of this Agreement through and inclusive
of the month of December, 1999.

         6.1 Governing Law. The validity, construction and enforcement of, and
