provided for in this Operating Agreement, action to be taken by the Managers

which might have been transacted at the meeting as originally noticed. The
Members present at a duly organized meeting may continue to transact business

Members holding a Majority Interest shall be the act of the Members, unless the

otherwise expressly provided herein or required under applicable law, only
Members who have a Membership Interest may vote or consent upon any matter and

                                      18

their vote or consent, as the case may be, shall be counted in the determination
of whether the matter was approved by the Members.

     7.08  Proxies.  At all meetings of Members, a Member may vote in person or
by proxy executed in writing by the Member or by a duly authorized attorney-in-
fact. Such proxy shall be filed with the Managers of the Company before or at

date of its execution, unless otherwise provided in the proxy.

be taken at a meeting of Members may be taken without a meeting if the action is
evidenced by one or more written consents describing the action taken, signed by
each Member entitled to vote and delivered to the Managers of the Company for
inclusion in the minutes or for filing with the Company records. Action taken
under this Section is effective when all Members entitled to vote have signed

     7.10  Waiver of Notice.  When any notice is required to be given to any
Member, a waiver thereof in writing signed by the person entitled to such
notice, whether before, at, or after the time stated therein, shall be
equivalent to the giving of such notice.

     7.11  Telephonic Meetings.  A Member may participate in a meeting of
Members by means of conference telephone or similar communications equipment
enabling all Members participating in the meeting to hear one another.
Participation in a meeting pursuant to this section shall constitute presence in

annual meeting, which shall occur during the month of November, KFx (for so long
as KFx owns a Majority Interest in the Company) shall submit to the other
Members a business plan and budget for the upcoming year for the approval of the
Members at the annual meeting. If such budget and or business plan is not
approved in accordance with Section 6:04, then such budget and or business plan,
at the request of any Member, shall be subject to Section 7:13 hereof.

Company, or between the Members, which in any way relate to this Amended and
Restated Operating Agreement, and such disputes cannot be resolved amicably, the

               CONTRIBUTIONS TO THE COMPANY AND CAPITAL ACCOUNTS

     8.01  Members' Capital Contributions.  The Initial Capital Contribution of
KFx is $2,200,000. The Capital Contribution of the Radl Group and Richard W.
Vesel was in the form of management services and the Capital Contribution of
AIW/P Holdings, Inc. was the granting of an exclusive license.

     8.02  Additional Contributions.  A Member or Economic Interest Owner shall
be required to make such additional Capital Contributions ("Additional Capital
Contributions") in the form and amount as shall be determined by the affirmative
vote of Members holding at least 86% of the Percentage Interests, from time to
time to be reasonably necessary to meet the expenses and obligations of the
Company (a "Shortfall").
 
     (a)   After the making of any such determination, the Managers shall give
written notice to each Member and Economic Interest Owner of the amount of the
required Additional Contribution, if any, and each Member and Economic Interest
Owner shall deliver to the Company its pro rata share thereof, (in proportion to
the respective Percentage Interest of the Member and Economic Interest Owner on
the date such notice is given or in such proportion as the Member Groups
otherwise determine) no later than thirty (30) days following the date such
notice is given.

     (b)   In the event any Member fails to make any Additional Capital
Contribution within the time specified (a "Non-Contributing Member"), the other
Members or any of them (the "Contributing Members") shall have the option to
contribute directly to the Company the funds required of the Non-Contributing
Member. If there is more than one Contributing Member each Contributing Member
shall pay that portion of the funds required of the Non-Contributing Member pro
rata based on that Member's Percentage Interest to the aggregate Percentage
Interests of the other Contributing Members, as determined prior to the request
for Additional Capital Contributions.

     (c)   Failure to Receive Shortfall.  In the event Additional Capital
Contributions are insufficient to satisfy the Shortfall, the project or action
for which the Shortfall was requested will either (i) not be taken, or (ii) the
Company shall enter into an arrangement with other Members or third parties to
meet the total Shortfall requested; provided, however, that should the Managers
elect to proceed under clause (ii), the Members must approve such decision in
accordance with the terms of this Operating Agreement.

     (d)   Adjustment to Capital Accounts.  Upon receipt of such Additional
Capital Contributions, the Capital Accounts and Percentage Interests of each
Member shall be adjusted to reflect such additional contributions.

                                      20

     (e)  None of the terms, covenants, obligations or rights contained in this
Section 8.02 is or shall be deemed to be for the benefit of any person or entity
other than the Members and the Company, and no such third person shall under any
circumstances have any right to compel any actions or payments by the Managers
and/or the Members.

     8.03 Capital Accounts.

          (a)  A separate Capital Account will be maintained for each Member and
 Economic Interest Owner. The Capital Account will be increased by (1) the
 amount of money contributed by such Member or Economic Interest Owner to the
 Company; (2) the fair market value of property contributed by such Member or
 Economic Interest Owner to the Company (net of liabilities secured by such
 contributed property that the Company is considered to assume or take subject
 to under Code Section 752); and (3) allocations to such Member or Economic
 Interest Owner of Net Profits and any other items of income or gain. Each
 Member's or Economic Interest Owner's Capital Account will be decreased by (1)
 the amount of money distributed to such Member or Economic Interest Owner by
 the Company; (2) the fair market value of property distributed to such Member
 or Economic Interest Owner by the Company (net of liabilities secured by such
 distributed property that such Member or Economic Interest Owner is considered
 to assume or take subject to under Code Section 752); and (3) allocations to
 such Member or Economic Interest Owner of Net Losses and any other items of
 loss or deduction.

          (b)  In the event of a permitted sale or exchange of a Membership
 Interest or an Economic Interest in the Company, the Capital Account of the
 transferor shall become the Capital Account of the transferee to the extent it
 relates to the transferred Membership Interest or Economic Interest in
 accordance with Section 1.704-1 (b)(2)(iv) of the Treasury Regulations.

          (c)  The manner in which Capital Accounts are to be maintained
 pursuant to this Section 8.03 is intended to comply with the requirements of
 Code Section 704(b) and the Treasury Regulations promulgated thereunder. If the
 Company determines that the manner in which Capital Accounts are to be
 maintained pursuant to the preceding provisions of this Section 8.03 should be
 modified in order to comply with Code Section 704(b) and the Treasury
 Regulations, then notwithstanding anything to the contrary contained in the
 preceding provisions of this Section 8.03, the method in which Capital Accounts
 are maintained shall be so modified, provided, however, that any change in the
 manner of maintaining Capital Accounts shall not materially alter the economic
 agreement between or among the Members or the Economic Interest Owner as set
 forth in the Operating Agreement.

          (d)  Upon liquidation of the Company (or any Member's Membership
 Interest or Economic Interest Owner's Economic Interest), liquidating
 distributions will be made in accordance with the positive Capital Account
 balances of the Members and Economic Interest Owner, as determined after taking
 into account all Capital Account adjustments for the

                                      21
<PAGE>
 
Company's taxable year during which the liquidation occurs. Liquidation proceeds
will be paid within sixty days of the end of the taxable year (or, if later,
within one hundred twenty days after the date of the liquidation). The Company
may offset damages for breach of this Operating Agreement by an Interest Holder
whose interest is liquidated (either upon the withdrawal of the Member or the
liquidation of the Company) against the amount otherwise distributable to such
Member.

          (e)  Except as otherwise required in the Act (and subject to Sections
8.01 and 8.02), no Interest Holder shall have any liability to restore all or
any portion of a deficit balance in such Interest Holder's Capital Account.

     8.04 Withdrawal or Reduction of Members' Contributions to Capital:

          (a)  Except as otherwise provided in Section 9.13, a Member shall not
receive out of the Company's property any part of its Capital Contribution until
all liabilities of the Company have been paid or there remains property of the
Company sufficient to pay them.

          (b)  A Member, irrespective of the nature of its Capital Contribution,
has only the right to demand and receive cash in return for its Capital
Contribution.


                                   ARTICLE 9.

             ALLOCATIONS, INCOME TAX, DISTRIBUTIONS, ELECTIONS AND
                                    REPORTS

     9.01  Allocation of Net Profits. Net Profits shall first be allocated in
proportion to, and to the extent of, the excess of prior allocations of Net
Losses under Section 9.02 below over prior allocation of Net Profits under this
Section 9.01 and, second, any remaining Net Profits shall be allocated among the
Members in proportion to their Percentage Interests.

     9.02  Allocation of Net Losses. Net Losses shall first be allocated among
the Members in proportion to and to the extent of the positive balances in their
respective Capital Accounts and, second, any remaining Net Losses shall be
allocated among the Members in proportion to their Percentage Interests.

     9.03  Treasury Regulation Allocations.  When the Book Value of a
Company asset differs from its basis for Federal or other income tax purposes,
solely for purposes of the relevant tax and not for purposes of computing
Capital Account balances, income, gain, loss, deduction and credit shall be
allocated among the Members under the remedial allocation method under Treasury
Regulations Section 1.704-3(d).
 
                                      22
<PAGE>
 
     9.04  Compliance with Code Section 704(b). Notwithstanding the foregoing,
if the amount of Net Losses that would otherwise be allocated to a Member would
cause or increase a Deficit Capital Account balance in such member's Capital
Account (an "Excess Deficit"), Net Losses equal to the amount thereof that would
cause or increase such Excess Deficit shall instead be allocated to the Members
to whom such Net Losses can be allocated without causing or increasing an Excess
Deficit.

     9.05  Minimum Gain Chargeback. In any Fiscal Year in which the Company has
"partnership minimum gain" (as determined under Treasury Regulations Section
1.704-2(d) or minimum gain attributable to any "partner nonrecourse liabilities"
(as determined under Treasury Regulations Section 1.704-2(i)), the provisions of
Treasury Regulations Section 1.704-2(f), (g) and (i) regarding chargebacks of
partnership minimum gain and minimum gain attributable to partner nonrecourse
liabilities shall apply.

     9.06  Partner Nonrecourse Liabilities. All deductions, losses and Code
Section 705(a)(2)(b) expenditures of the Company, as the case may be (all
computed for "book" purposes), that are treated under Section 1.704-2(i) of the
Treasury Regulations as deductions, losses, and expenditures attributable to
"partner recourse liabilities" of the Company shall be allocated to the Members
bearing the risk of loss with respect to such liabilities in accordance with
such Treasury Regulations.

     9.07  Qualified Income Offset. If any Member unexpectedly receives an
adjustment allocation or distribution described in subparagraph (4), (5) or (6)
of Section 1.704-1(b)(ii)(d) of the Treasury Regulations, which adjustment,
allocation or distribution creates or increases an Excess Deficit in such
Member's Capital Account, then such Member shall be allocated items of "book"
income and gain in an amount and manner sufficient to eliminate or to reduce, as
quickly as possible, the Excess Deficit so created or increased. For purposes of
this Section 9.07, Capital Accounts shall be adjusted hypothetically as provided
for in Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations. The Members
intend that the provisions set forth in this Section 9.07 shall constitute a
"qualified income offset" as described in Section 1.704-1(b)(2)(ii)(d) of the
Treasury Regulations. Such provision of the Treasury Regulation shall control in
the case of any conflict between that provision of the Treasury Regulations and
this Section 9.07.

     9.08  Curative Allocations. To the extent necessary to avoid any economic
distortions which may result from application of the Regulatory Allocations,
items of income, gain, loss, expense and deduction shall be allocated as
appropriate in the reasonable discretion of the Managers in order to remedy any
economic distortions that the Regulatory Allocations might otherwise cause, for
purposes hereof, "Regulatory Allocations" shall mean the allocations provided
under Sections 9.03 through 9.07.

     9.09  Section 754 Election. At the request of any Member, the Managers
shall file an election on behalf of the Company pursuant to Section 754 of the
Code to adjust the basis of Company property in the case of a transfer of a
Partnership Interest.

     9.10  Distributions. A Member has no right to demand and receive any
distribution in a form other than cash. All distributions of cash or other
property shall be made to the Members pro rata in proportion to the respective
Percentage Interests of the Members on the record date of such distribution.
Except as provided in Section 9.11, all distributions of Distributable Cash and
property shall be made at such time as determined by the Mangers. All amounts
withheld pursuant to the Code or any provisions of state or local tax law with
respect to any payment or distribution to the Members from the Company shall be
treated as amounts distributed to the relevant Member or Members pursuant to
this Section 9.08.

     9.11  Limitation upon Distributions.

           (a)  No distributions, priority or otherwise, or return of
contributions be made and paid if, after the distribution or return of

analysis);

                (2)  the net book or, alternatively, fair market value of the
assets less the liabilities of the Company would be less than zero; or

                (3)  the Company's Reserves would be reduced below such amount
as the Managers may from time to time establish (pursuant to the affirmative
vote of 86% of the Members).

           (b)  The Managers may base a determination that a distribution or
return of contribution may be made under Section 9.11 in good faith reliance
upon a balance sheet and profit and loss statement of the Company represented to
be correct by the person having charge of its books of account, or certified by
an independent public or public accountant or firm of accountants to fairly
reflect the financial condition of the Company.

     9.12  Accounting Principles. The profits and losses of the Company shall be
determined in accordance with generally accepted accounting principles applied
on a consistent basis using the cash method of accounting.

     9.13  No Interest on Return of Capital. No Member or group shall be
entitled to interest on, or a return of, its Capital Contribution.

any Member from making secured or other loans to the Company by agreement with
the Company.

     9.15  Accounting Period. The Company's accounting period shall be the
calendar year ("Fiscal Year").

                                  ARTICLE 10.

                                TRANSFERABILITY

     10.01 General.  Except as otherwise specifically provided herein, no
Interest Holder shall have the right, as to all or any part of its Membership
Interest or Economic Interest to:

           (a)   Sell, assign pledge, hypothecate, transfer, exchange or
otherwise transfer for consideration, (collectively, "sell"); or

           (b)   Gift, bequeath or otherwise transfer for no consideration
(whether or not by operation of law, except in the case of bankruptcy).

     10.02 Right of First Refusal.

           (a)   Subject to the Radl Group's Earn-Back Option as set forth in
section 10.05, each Member may sell their Membership Interests to other Members.
Richard W. Vesel may sell his Economic Interest to other Members.

           (b)   If a Selling Member desires to sell all or any portion of its
Membership Interest or Economic Interest in the Company to a third party
purchaser, the selling Member shall obtain from such third party purchaser a
bona fide written offer to purchase such interest, stating the terms and
conditions upon which the purchase is to be made and the consideration offered.
The selling Member shall give written notification to the remaining Members, by
certified mail or personal delivery, of its intention to so transfer such
interest.

                                      26
<PAGE>
 
           (c)   Primary Option to Purchase. Within 35 days after the receipt of
the notice of intention to transfer a Percentage Interest (as set forth in
Section 13.01) each remaining Member may exercise an option to purchase that
proportion of the Percentage Interest proposed to be transferred which equals
the proportion which the Percentage Interest owned by such remaining Member at
the time of his receipt of the notice is of the total of the Percentage
Interests then owned by all the remaining Members. The purchase option granted
in this paragraph is herein referred to as the "Primary Option."

           (d)   Secondary Option to Purchase. If a Member fails to exercise a
Primary Option granted to him to purchase the Percentage Interest proposed to be
transferred, each remaining Member who is granted and who exercises a Primary
Option may, within ten days after the expiration of the 35-day option period
provided for above, exercise an option to purchase the Percentage Interest with
respect to which such Member has failed to exercise his Primary Option
(hereinafter "the Option Interest"). In the case of a single remaining Member,
his option shall be to purchase all of the Option Interest. In the case of two
or more remaining Members, each such remaining Member's option shall be to
purchase the portion of Option Interest which bears the same proportion to the
total Option Interest as the Percentage Interest owned by each such remaining
Member at the time of receipt of the notice provided for above bears to the
total Percentage Interest then owned by all such remaining Members; provided
that all such remaining Members may, by agreement among themselves, determine
the proportions in which some or all of their number may exercise the option
granted in this paragraph. The purchase option granted by this paragraph is
referred to a the "Secondary Option."

           (e)   In the event the remaining Members (or any one or more of the
Members) give written notice to the selling Member of their desire to exercise
this right of first refusal and to purchase all of the selling Member's interest
in the Company which the selling Member desires to sell upon the same terms and
conditions as are stated in the aforesaid written offer to purchase, the
remaining Members shall have the right to designate the time, date and place of
closing, provided that the date of closing shall be within sixty days after
written notification to the Selling Member of the remaining Member or Members'
election to exercise their right of the first refusal.

           (f)   As a condition to the Company recognizing the effectiveness of
either the purchase of the Selling Member's interest in the Company by a third
party purchaser or the gift of an interest in the Company (including an Economic
Interest), (subject to Section 10.04) substitution of a new Member, the
remaining Members may require the Selling Member, Gifting Member or the proposed
purchaser, donee or successor-in-interest, as the case may be, to execute,
acknowledge and deliver to the remaining Members such instruments of transfer,
assignment and assumption and such other certificates, representations and
documents to perform all such other acts which the remaining Members may deem
necessary or desirable to:

                 (1)  verify the purchase, gift or transfer, as the case may be;

                                      27
<PAGE>
 
                 (2)  confirm that the person desiring to acquire an interest in
the Company, or to be admitted as a Member, has accepted, assumed and agreed to
be subject and bound by all of the terms, obligations and conditions of the
Operating Agreement, (whether such Person is to be admitted as a new Member or
an Economic Interest Owner);

                 (3)  maintain the status of the Company as a partnership for
federal tax purposes; and

                 (4)  assure compliance with any applicable state and federal
laws including securities laws and regulations.

           (g)   Any sale or gift of a Membership Interest or Economic Interest
or admission of a Member in compliance with this Article 10. shall be deemed
effective as of the last day of the calendar month in which such transfer was
made, or, if no such consent was required pursuant to Section 10.03(c), then on
such date that the donee or successor interest complies with the conditions set
forth in Section 10.03(c). The Selling Member agrees, upon request of the
remaining Members, to execute such certificates or other documents and to
perform such other acts as may be reasonably requested by the remaining Members
from time to time in connection with such sale, transfer, assignment, or
substitution. The Selling Member hereby indemnifies the Company and the
remaining Members against any and all loss, damage, or expense (including,
without limitation, tax liabilities or loss of tax benefits) arising directly or
indirectly as a result of any transfer or purported transfer in violation of
this Article 10.

     10.03   Transferee Not Member in Absence of Unanimous Consent.

           (a)   Notwithstanding anything contained herein to the contrary
(including, without limitation, Section 10.03 hereof), if all of the remaining
Members do not approve by unanimous written consent of the proposed sale or gift
of the Transferring Member's Membership or Economic Interest to a transferee or
donee which is not a Member immediately prior to the sale or gift, then the
proposed transferee or donee shall have no right to participate in the
management of the business and affairs of the Company or to become a Member. The
transferee or donee shall be merely an Economic Interest Owner. No transfer of a
Member's interest in the Company (including any transfer of the Economic
Interest or any other transfer which has not been approved by unanimous written
consent of the Members) shall be effective unless and until written notice
(including the name and address of the proposed transferee or donee and the date
of such transfer) has been provided to the Company and the non-transferring
Member(s).

           (b)   Upon and contemporaneously with any sale or gift of a
Transferring Member's Economic Interest in the Company which does not at the
same time transfer the balance of the rights associated with the Economic
Interest transferred by the Transferring Member (including, without limitation,
the rights of the Transferring Member to participate in

                                      28
<PAGE>
 
the management of the business and affairs of the Company), all rights and
interest which were owned by the Transferring Member immediately prior to such
sale or gift or which were associated with the transferred Economic Interest
shall immediately lapse until either (1) the remaining Members, by unanimous
consent, reinstate such rights to the Economic Interest Owner who did not
previously obtain the unanimous written consent of the Members or (2) upon the
remaining Members, by unanimous written consent, reinstating such rights to a
successor or transferee of such Economic Interest Owner.

          (c)   The restrictions on transfer contained in this Section 10.03
are intended to comply (and shall be interpreted consistently) with the
restrictions on transfer set forth in Article 30 of the Act.

     10.04 Purchase on Death.

          (a)   Upon the death of any Member who is an employee of the Company
("Active Member"), the Company (subject to the substitute Economic Interest
Owner election in 10.05(b) hereof), shall have the obligation to purchase all of
the Membership Interest owned by such Active Member either: (i) in lump sum
within ninety (90) days, or (ii) in monthly installments not to exceed three (3)
years, after qualification of the decedent's administrator, executor, or
personal representative. The Company may elect either payment option in its sole
discretion. The purchase price for such Membership Interest shall be as mutually
agreed upon or, failing agreement, at such price as may be determined by a
mutually acceptable independent valuator, and shall bear interest at a minimum
rate to avoid the imputation of interest by the Internal Revenue Service. The
independent valuator is not permitted to consider minority interest or lack of
liquidity to determine the purchase price for such Membership Interest.

          (b)   Notwithstanding the provisions of Section 10.05(a) above, a
spouse, heir or designated beneficiary of a deceased Member shall have the right
to become a substitute Economic Interest Owner (but not a Member), pursuant to
any trust, will, inheritance, or similar mechanism. In the event such spouse,
heir or designated beneficiary desires to become a substitute Economic Interest
Owner, such person shall serve written notice on the Company within ninety (90)
days of the date of death of such Member.

     10.05 Earn-Back Option.

          (a)   KFx and the Radl Group have entered into a certain Earn-Back
Letter Agreement (the "Earn-Back Agreement"), of even date herewith, whereby KFx
shall transfer and/or sell 40 percent of its Membership Interests to the Radl
Group subject to the terms and conditions as more specifically set forth in the
Earn-Back Agreement.

          (b)   Each member, by entering into this Operating Agreement
acknowledges and consents to the terms, conditions and provisions of the Earn
Back Agreement.

                              ADDITIONAL MEMBERS

     11.01 From the date of the formation of the Company, any Person or Entity
acceptable to the Members by their unanimous vote thereof may become a Member in
this Company either by the issuance by the Company of Membership Interests for
such consideration as the Members by their unanimous votes shall determine, or
as a transferee of a Member's Membership Interest or any portion thereof,
subject to the terms and conditions of this Operating Agreement. No new Members
shall be entitled to any retroactive allocation of losses, income or expense
deductions incurred by the Company. The Manager(s) may, at their option, at the
time a Member is admitted, close the Company books (as though the Company's tax
year has ended) or make pro rata allocations of loss, income and expense
deductions to a new Member for that portion of the Company's tax year in which a
Member was admitted in accordance with the provisions of Code Section 706(d) and
the Treasury Regulations promulgated thereunder.

                                  ARTICLE 12.

     12.01 Dissolution.

           (a)   The Company shall be dissolved upon the occurrence of any of
following events:

                 (1)  when the period fixed for the duration of the Company
shall expire pursuant to Section 2.05 hereof;

                 (2)  by the unanimous written agreement of all Members; or

                 (3)  upon the happening of a Withdrawal Event, unless the
business of the Company is continued by the consent of all the remaining Members
within ninety (90) days after the Withdrawal Event and there are at least two
remaining Members.

           (b)   Notwithstanding anything to the contrary in this Operating
Agreement, if a Member or Members owning in the aggregate not less than 86% of
the Percentage Interests vote to dissolve the Company at a meeting of the
Company pursuant to Article 7, then all of the Members shall agree in writing to
dissolve, or sell the assets of, the Company on the date upon or in the event of
no agreement, as soon as possible, but in any event not more than thirty days
thereafter.

           (c)   If a Member who is an individual dies or a court of competent
jurisdiction adjudges him to be incompetent to manage his person or his
property, the Member's executor,

                                      30

administrator, guardian, conservator, or other legal representative may exercise
all of the Member's rights for the purpose of settling his estate or
administering his property.

           (d)   A Member shall not take any voluntary action which directly
causes a Withdrawal Event. Unless otherwise approved by Members owning a
Majority Interest, a Member who resigns (a "Resigning Member") or whose
Membership Interest is otherwise terminated by virtue of a Withdrawal Event,
regardless of whether such Withdrawal Event was the result of a voluntary act by
such Member, shall not be entitled to receive any distributions in excess of
those distributions to which such Member would have been entitled had such
Member remained a Member. Except as otherwise expressly provided herein, a
Resigning Member shall immediately become an Economic Interest Owner. Damages
for breach of this Section 12.01(d) shall be monetary damages only (and not
specific performance), and such damages may be offset against distributions by
the Company to which the Resigning Member would otherwise be entitled.

     12.02  Winding Up, Liquidation and Distribution of Assets.

           (a)   Upon dissolution, an accounting shall be made by the Company's
independent accountants of the accounts of the Company and of the Company's
assets, liabilities and operations, from the date of the last previous
accounting until the date of dissolution. The Managers shall immediately proceed
to wind up the affairs of the Company.

           (b)   If the Company is dissolved and its affairs are to be wound up,
the Managers shall:

                 (1)  Sell or otherwise liquidate all of the Company's assets as
promptly as practicable (except to the extent the Managers may determine to
distribute any assets to the Members in kind),

                 (2)  Allocate any profit or loss resulting from such sales to

liabilities to Members and Economic Interest Owners who are creditors, to the
extent otherwise permitted by law, other than liabilities to Members and
Economic Interest Owners for Distributions, and establish such Reserves as may
be reasonably necessary to provide for contingent liabilities of the Company
(for purposes of determining the Capital Accounts of the Members and Economic

                      (i)  If any assets of the Company are to be distributed in
kind, the net fair market value of such assets as of the date of dissolution
shall be determined by independent appraisal or by agreement of the Members.
Such assets shall be deemed to have been sold as of the date of dissolution for
their fair market value, and the Capital Accounts of the Members and Economic
Interest Owners shall be adjusted pursuant to the provisions of Article 9. and
Section 8.03 of this Operating Agreement to reflect such deemed sale.

                      (ii) The Positive balance (if any) of each Member's and
Economic Interest Owner's Capital Account (as determined after taking into
account all Capital Account adjustments for the Company's taxable year during
which the liquidation occurs) shall be distributed to the Members, either in
cash or in kind, as determined by the Managers, with any assets distributed in
kind being valued for this purpose at their fair market value as determined
pursuant to Section 12.02 (b) (i). Any such distributions to the Members in
respect of their Capital Accounts shall be made in accordance with the time
requirements set forth in Section 1.704.1(b)(2)(ii)(b)(2) of the Treasury
Regulations.

           (c)   Notwithstanding anything to the contrary in this Operating
Agreement, upon a liquidation within the meaning of Section 1.704-1 (b) (2) (ii)
(g) of the Treasury Regulations, if any Member has a Deficit Capital Account
(after giving effect to all contributions, distributions, allocations and other
Capital Account adjustments for all taxable years, including the year during
which such liquidation occurs), such Member shall have no obligation to make any
Capital Contribution, and the negative balance of such Member's Capital Account
shall not be considered a debt owed by such Member to the Company or to any
other Person for any purpose whatsoever.

           (d)   Upon completion of the winding up, liquidation and distribution
of the assets, the Company shall be deemed terminated.

           (e)   The Manager(s) shall comply with all requirements of applicable
law pertaining to the winding up of the affairs of the Company and the final
distribution of its assets.

     12.03 Articles of Dissolution. When all debts, liabilities and obligations
of the Company have been paid and discharged or adequate provisions have been
made therefore and all of the remaining property and assets of the Company have
been distributed, articles of dissolution as required by the Act, shall be
executed in duplicate and filed with the Ohio Secretary of State.

     12.04 Effect of Filing of Articles of Dissolution. Upon the filing of
articles of dissolution with the Ohio Secretary of State, the existence of the
Company shall cease, except for the purpose of suits, other proceedings and
appropriate action as provided in the Act. The Managers shall have authority to
distribute any Company property discovered after dissolution, convey real estate
and take such other action as may be necessary on behalf of and in the name of
the Company.

     12.05  Return of Contribution Nonrecourse to Other Members. Except as
provided by law or as expressly provided in this Operating Agreement, upon
dissolution, each Member shall look solely to the assets of the Company for the
return of its Capital Contribution. If the Company property remaining after the
payment or discharge of the debts and liabilities of the Company is insufficient
to return the cash contribution of one or more Members, such Member or Members
shall have no recourse against any other Member, except as otherwise provided by
law.

                                  ARTICLE 13.
