respect to clauses (ii) and (iii) above, where failure to be so qualified or be

                           (b)      DUE AUTHORIZATION; NON-CONTRAVENTION. The
execution, delivery and performances of this Agreement and each of the Operative
Documents to which it is or will be a party have been or when executed and
delivered will be duly authorized by all necessary company action and do not and

                                    (i)      contravene the Organic Documents of
         Midwest;

                                    (ii)     contravene any Requirement of Law
         or Contractual Obligation, binding on or affecting Midwest; or

                                    (iii)    result in, or require the creation
         or imposition of, any Lien (other than pursuant to the Operative
         Documents) on any of the properties of Midwest.

                  In case of clauses (ii) and (iii), except where such
contravention, creation or imposition would not result in a Material Adverse
Effect on Midwest.

                           (c)      GOVERNMENT APPROVALS. (i) As of the Closing
Date, all Governmental Approvals required in connection with the execution and
delivery of, or the transactions contemplated by, this Agreement and the other
Operative Documents to which Midwest is a party and the conduct of the business
by Midwest are listed on SCHEDULE 3.1 (c) and have been duly obtained or made
and are in full force and effect, in each case, other than (a) as may be
required under existing Requirements of Law to be obtained, given, accomplished
or renewed at any time after the Closing Date or from time to time after the
Closing Date in connection with the maintenance or operation of the Facility,
(b) which are routine in nature and which cannot be obtained and such failure to
obtain would not result in a Material Adverse Effect on Midwest, or are not
normally applied for, prior to the time they are required, and which Midwest has
no reason to believe will not be timely obtained, (c) as may be required in
connection with any refinancing of the Lessor Notes or the issuance of
Additional Lessor Notes, (d) as may be required in consequence of any transfer
of the Beneficial Interest or any transfer of ownership of the Undivided
Interest or the Trust Estate by the Owner Lessor or any relinquishment of the

recording to perfect the Lien of the Holder Representative, and the ownership
and leasehold interests conveyed pursuant to this Agreement to the extent
arrangements have been made satisfactory to the Owner Participant, the Owner
Lessor and the Holder Representative. Except as noted in Part B of SCHEDULE 3.1
(c), all Governmental Approvals that have been obtained pursuant to the first
sentence of this SECTION 3.1(c) are final and any period for the filing of
notice of rehearing or application for judicial review of the issuance of each
such Governmental Approval has expired without any such notice or


                                      -9-

<PAGE>



application having been made. No such Governmental Approval is the subject of
any pending or, except as indicated in PART C of SCHEDULE 3.1 (c), threatened
judicial or administrative proceeding.

                                    (ii)     As of the Closing Date, all
         consents and approvals required to be obtained from Persons other than
         Governmental Authorities in connections with the transactions
         contemplated by the Operative Documents and the ASA have been obtained
         and are in full force and effect, other than such consents or approvals
         the failure of which to obtain, would not, individually or in the
         aggregate, result in a Material Adverse Effect on Midwest.

                           (d)      ACCURACY OF INFORMATION. (i) All factual
information listed on SCHEDULE 3.1(d) (other than projection and
"forward-looking" information) is true and materially accurate in every material
respect on the date as of which such information is dated or certified, and to
the knowledge of Midwest, such information is not incomplete by omitting to
state any material fact necessary in order to make the statements contained
therein, in light of the circumstances under which they are made, not
misleading.

                                    (ii)     All projections and other "forward-
         looking" information heretofore or contemporaneously furnished by
         Midwest and its Affiliates in writing to the Owner Participant, the OP
         Guarantor, the Owner Lessor, the Holder Representative, the Lender and
         any of the Funding LLC Note Holders for purposes of this Agreement or
         the transactions contemplated by the other Operative Documents were
         prepared in good faith and are based on reasonable assumptions.

                           (e)      VALIDITY. Each of the Operative Documents to
which Midwest is a party constitutes, or, upon the due execution and delivery
thereof by Midwest, will constitute, the legal, valid and binding obligation of
Midwest enforceable in accordance with its terms (except as may be limited by
bankruptcy, insolvency or other similar laws affecting the enforcement of
creditors' rights generally and general principles of equity and except as
indicated in the legal opinion of SASM&F delivered pursuant to SECTION 4.21
hereof).

                           (f)      COMPLIANCE WITH REQUIREMENTS OF LAW. Midwest
is in compliance with all Requirements of Law (including ERISA and regulations
of the Federal Reserve System) and Contractual Obligations applicable to it,
except to the extent that failure to so comply would not result in a Material
Adverse Effect on Midwest.

                           (g)      MARGIN REGULATION. Midwest is not engaged in
the business of extending credit for the purposes of purchasing or carrying
margin stock, and


                                      -10-

<PAGE>

no proceeds of the Lessor Notes and the Equity Investment as contemplated by
this Agreement and the other Operative Documents will be used for a purpose
which violates, or would be inconsistent with, the Regulations T, U and X of the
Federal Reserve System. Terms for which meanings are provided in the Regulations
T, U and X of the Federal Reserve System or any regulations substituted
therefor, as from time to time in effect, are used in this SECTION 3.1 with such
meanings.

                           (h)      LITIGATION. There is no pending or, to the
knowledge of Midwest, threatened, action, suit, investigation or proceeding or
labor controversy against Midwest or any of its properties, business, assets or
revenues or affecting any Governmental Approval before any Governmental
Authority which, if determined adversely to Midwest (taking into account any
insurance proceeds payable under a policy where the insurer has accepted
coverage without any reservations), would result in a Material Adverse Effect on
Midwest.

                                    (i)      TITLE; LIENS. (i) Midwest has good,
         clear, marketable record fee title in the Facility Site, free and clear
         of all Liens, encumbrances or title defects other than Permitted
         Encumbrances and Lease Permitted Liens.

                                    (ii)     Upon execution and delivery of the
         Operative Documents and recording of the instruments referred to in
         SCHEDULE 4.19, good, clear, record and valid leasehold interest in the
         Ground Interest will be duly, validly and effectively conveyed to the
         Owner Lessor upon the terms and conditions in the Facility Site Lease,
         free and clear of all Liens, encumbrances or title defects other than
         Permitted Encumbrances and Lease Permitted Liens.

                                    (iii)    Giving effect to the transaction
         contemplated by the ASA and upon execution and delivery of the
         Operative Documents, good, clear, record and marketable fee simple
         title to the Undivided Interest will be duly, validly and effectively
         conveyed to the Owner Lessor, free and clear of all Liens,
         encumbrances or title defects other than Permitted Encumbrances and
         Lease Permitted Liens.

                                    (iv)     None of the Permitted Encumbrances
         and Lease Permitted Liens will, on and after the Closing, materially
         interfere with the use, operation or possession of the Facility (as
         contemplated by the Operative Documents) or the use of or the exercise
         by the Owner Lessor of its rights under the Facility Site Lease with
         respect to the Facility.

                           (l)      INVESTMENT COMPANY ACT. Midwest is not

         to register under PUHCA or (ii) public utility regulation or regulation
         as an alternative retail electric supplier under the laws of the State

                           (n)      ENVIRONMENTAL WARRANTIES. Except as has not
or would not, individually or in the aggregate, result in a Material Adverse
Effect on Midwest:

                                    (i)      (A) To the knowledge of Midwest,

<PAGE>


                                    (iii)    Midwest has obtained (or will
         obtain in due course promptly after the Closing Date) and is in
         compliance with all Governmental Approvals required under any
         applicable Environmental Law necessary for its business and, with
         respect to the Governmental Approvals not obtained by the Closing Date,
         (a) Midwest has no reason to believe that such approvals will not be
         timely obtained and (b) the failure to have obtained such Governmental
         Approvals by the Closing Date will not result in a Material Adverse
         Effect on Midwest.

                                    (iv)     No property owned, leased or
         operated by Midwest is listed or, to the knowledge of Midwest, is
         proposed for listing on the National Priorities List pursuant to any
         Environmental Law, on the CERCLIS or on any similar state or local
         list of sites requiring investigation or clean-up.

                                    (v)      To the knowledge of Midwest, no
         Environmental Conditions exist at, on, under or about any property
         owned, operated or leased by Midwest which, with the passage of time,
         or the giving of notice or both, would give rise to any Environmental
         Claim.

                                    (vi)     Other than as provided in the ASA,
         Midwest has not assumed or retained, by contract or operation of law,
         any liabilities of any kind, fixed or contingent, known or unknown,

whole are Year 2000 Ready.

                           (p)      PENSION AND WELFARE PLANS.  During the
consecutive twelve-month period prior to each date as of which the following
representations are made or deemed made, no steps have been taken to terminate
any Pension Plan; no contribution failure has occurred with respect to any
Pension Plan sufficient to give rise to a Lien under Section 302(f) of ERISA or
Section 412 of the Code; no condition exists or event or transaction has
occurred with respect to any Pension Plan which could reasonably be expected to
result in the incurrence by Midwest or any member of the Controlled Group of any
material liability (other than liabilities incurred in the ordinary course of
maintaining the Pension Plan), fine or penalty and none of the following events
or conditions, either individually or in the aggregate, has resulted or is
reasonably likely to result in a material liability to Midwest or any member of
the Controlled Group: (i) a Reportable Event; (ii) a complete or partial
withdrawal from any Multiemployer Plan by

                                      -13-

any member of the Controlled Group under ERISA if Midwest or any member of the
Controlled Group were to withdraw completely from all Multiemployer Plans as of
the annual valuation date most closely preceding the date on which this
representation is made or deemed made; or (iv) the Reorganization or Insolvency
of any Multiemployer Plan. Neither Midwest nor any member of the Controlled
Group has any contingent liability with respect to any post-retirement benefit
under a Welfare Plan which could reasonably be expected to have a Material
Adverse Effect on Midwest, other than liability for continuation coverage
described in Part 6 of Title I of ERISA.

                           (q)      LOCATION OF CHIEF EXECUTIVE OFFICE AND
PRINCIPAL PLACE OF BUSINESS, ETC. The chief executive office and principal place
of business of Midwest and the office where Midwest keeps its corporate records
concerning the Facility, the Facility Site and the Operative Documents is
located at One Finance Place, 440 South LaSalle Street, Suite 3500, Chicago,
Illinois 60605.

                           (r)      ACCESS; EGRESS.  Midwest has sufficient

rights necessary to deliver power to the point of interconnection to the
electricity grid.

                           (t)      POWER SALES AGREEMENTS AND OTHER CONTRACTS.
There are no contracts or agreements providing for sales of power and ancillary
services produced by the Facility or for the use and operation of the Facility
that have a term which extends beyond the expiration of the Basic Lease Term
other than the Interconnection Agreements.

                           (u)      UTILITY SERVICES.  The Facility and the
Facility Site have available all public utility necessary services for the use
and operation of the Facility as currently being used and as contemplated by the
Operative Documents.

                           (v)      SUBDIVISION.  No subdivision is necessary
in connection with the transaction contemplated by Operative Documents.

                           (w)      ADEQUATE RIGHTS.  Based upon Requirements of
Law in effect on the Closing Date, the rights and interests made, or to be made
available to the Owner Lessor or its permitted transferees pursuant to the
Operative Documents, together with the rights of the Owner Lessor as owner of
the Undivided Interest, are sufficient to permit the following actions by the
Owner Lessor or any such permitted transferee

                                      -14-

<PAGE>

use, operation and possession of the Facility, (iii) the construction, use,
operation, possession, maintenance and renewal of all modifications, additions,
improvements, replacements and substitutions thereof and thereto, (iv)
appropriate ingress to and egress from the Facility for any reasonable purpose
in connection with the exercise of rights under the Operation Agreement and such
Person's interest in the Facility, (v) access to the off-site unloading dock,
transportation and storage areas for fuel handling, storage and transportation
and access to the off-site lake for water-cooling, (vi) transmission of the
electric energy and ancillary services provided by the Facility to the nearest
point of interconnection to the relevant electricity grid and (vii) the disposal
of by-products and waste from the Facility.

                           (x)      RETURN ACCEPTANCE TESTS.  Midwest has no
reason to believe that the Facility will not be able to satisfy the return
conditions set forth in SECTION 5 of the Facility Lease as of the expiration of
the Facility Lease Term if the Facility is maintained in accordance with Section
7 of the Facility Lease.

                           (y)      REPRESENTATIONS OF COLLINS HOLDINGS.  The
representations of Collins Holdings set forth in Section 3.3 hereof are true and
correct.

                           (z)      NO DEFAULTS. NO EVENT OF LOSS.  No Lease
Event of Default, Material Lease Default or event that with the passage of time
or notice or both would constitute a Lease Event of Default has occurred or will

Documents.

Documents to which it is or will be a party and to conduct its business as
currently conducted and currently expected to be conducted, except, with respect
to clauses (ii) and (iii) above, where failure to be so qualified or be in good
standing or the failure to obtain such Governmental Approvals would not,
individually or in the aggregate, cause a Material Adverse Effect on Holdings.
All of the equity interest in Holdings is owned by MGE.

                           (c)      DUE AUTHORIZATION; NON-CONTRAVENTION.  The

                  imposition of, any Lien (other than pursuant to the Operative
                  Documents) on any of the properties of Holdings.

                  In case of clauses (ii) and (iii), except where such

Trustee, the Owner Lessor or the Owner Participant, if there has been a Lease

         received an opinion of counsel, which opinion and counsel are
         reasonably satisfactory to each recipient thereof, to the effect that
         such Assignment and Assumption Agreement is a legal, valid and binding
         obligation of, and is enforceable against, each party thereto, that all
         regulatory approvals required in connection with such transfer or
         necessary to assume the Owner Participant's obligations under the
         Operative Documents shall have been obtained and that the proposed

         Tangible Net Assets of at least equal to $75 million calculated
         in accordance with GAAP, (2) agrees to be bound by the terms of the

the Owner Participant's contemplated investment in this transaction, (ii) such

be released from all obligations hereunder and under each other Operative
Document to which such transferor or Guarantor is a party or by which such

                           (viii)   any Claim relating to the payment of any
         amount which constitutes Transaction Costs which the Owner Participant
         is obligated to pay pursuant to SECTION 2.3(a) hereof or any other
         amount to the extent such Indemnitee or a Related Party has expressly
         agreed in any Operative Document to pay such amount without a right of
         reimbursement;

                           (ix)     any Claim that is a Tax, or is a cost of
         contesting a Tax, whether or not Midwest is required to indemnify
         therefor pursuant to SECTION 14.2 or under the Tax Indemnity
         Agreement;

                           (x)      any failure on the part of the Owner Trustee
         to distribute in accordance with the Trust Agreement any amounts
         received by it under the Operative Documents and distributable by it
         thereunder;

                           (xi)     any Claim relating to the costs and expenses
         of any Indemnitee in connection with any amendments or supplements to
         the Operative Documents requested by such Indemnitee or a Related Party
         if such amendment or supplement is not required by the Operative
         Documents;

                           (xii)    any Claim that constitutes principal and/or
         interest on the Lessor Notes, any Additional Lessor Notes or the
         corresponding payments under the Funding LLC Notes on any Additional
         Funding LLC Notes, respectively;

                           (xiii)   any Claim that constitutes the RCE LC
         Reimbursement Obligations and any interest thereon; and

                           (xiv)    any Claim arising out of obligations
         expressly assumed by the Indemnitee seeking indemnification or a
         Related Party thereof.

PROVIDED that the terms "omission," "gross negligence" and "willful misconduct,"
when applied with respect to the Owner Trustee, the Owner Participant, the OP
Guarantor, the Equity Investor, the Owner Lessor, Citicorp North America, Inc.,
Lord Securities Corporation, Midwest Funding, Inc., the Holder Representative,
any Holder, the Midwest LC Issuer, the RCE LC Issuer, any Funding LLC Note
Holder, the RCE Agent, the APA Agent, each APA Purchaser, the Surety or any
Affiliate of any thereof, shall not include any liability imputed as a matter of
law to such Indemnitee solely by reason of such

                                      -66-

<PAGE>

entity's interest in the Facility or the Facility Site or such Indemnitee's
failure to act in respect of matters which are or were the obligation of Midwest
under this Agreement or any other Operative Document.

                  (c)      INSURED CLAIMS. Subject to the provisions of
paragraph (e) of this SECTION 14.1, in the case of any Claim indemnified by
Midwest hereunder which is covered by a policy of insurance maintained by
Midwest, each Indemnitee agrees, unless it and each other Indemnitee shall waive
its rights to indemnification (for itself and each Related Party thereto) in a
manner reasonably acceptable to Midwest, to cooperate, at the sole cost and
expense of Midwest, with insurers in exercise of their rights to investigate,
defend or compromise such Claim.

                  (d)      AFTER-TAX BASIS. Midwest agrees that any payment or
indemnity pursuant to this SECTION 14.1 in respect of any Claim shall be made on
an After-Tax Basis to the Indemnitees.

                  (e)      CLAIMS PROCEDURE. Each Indemnitee shall promptly
after such Indemnitee shall have actual knowledge thereof notify Midwest in
writing of any Claim as to which indemnification is sought; PROVIDED, that the
failure so to notify Midwest shall not reduce or affect Midwest's liability
which it may have to such Indemnitee under this SECTION 14.1. Any amount payable
to any Indemnitee pursuant to this SECTION 14.1 shall be paid within fifteen
(15) days after receipt of such written demand therefor from such Indemnitee,
accompanied by a certificate of such Indemnitee stating in reasonable detail the
basis for the indemnification thereby sought and (if such Indemnitee is not a
party hereto) an agreement to be bound by the terms hereof as if such Indemnitee
were such a party. The foregoing shall not, however, constitute an obligation to
disclose confidential information of any kind without the execution of an
appropriate confidentiality agreement. Promptly after Midwest receives
notification of such Claim accompanied by a written statement describing in
reasonable detail the Claims which are the subject of and basis for such
indemnity and the computation of the amount so payable, Midwest shall notify
such Indemnitee in writing whether it intends to pay, object to, compromise or
defend any matter involving the asserted liability of such Indemnitee. Midwest
shall have the right to investigate and so long as no Material Lease Default or
Lease Event of Default shall have occurred and be continuing, Midwest shall have
the right in its sole discretion, to defend or compromise any Claim for which
indemnification is sought under this SECTION 14.1 which Midwest acknowledges in
writing to the applicable Indemnitee is subject to indemnification hereunder;
PROVIDED that no such defense or compromise shall involve any danger of (i)
foreclosure, sale, forfeiture or loss of, or imposition of a Lien on any part of
the Undivided Interest, the Ground Interest, the Trust Estate or the Lessor
Collateral or the impairment of the Facility in any material respect or (ii) any
criminal liability being incurred or any material adverse effect on such
Indemnitee, PROVIDED, FURTHER, that no Claim shall be compromised by Midwest on
a basis that admits any

                                      -67-

<PAGE>

criminal violation or gross negligence or willful misconduct on the part of such
Indemnitee without the express written consent of such Indemnitee; and PROVIDED,
FURTHER, that to the extent that other Claims unrelated to the transactions
contemplated by the Operative Documents are part of the same proceeding
involving such Claim, Midwest may assume responsibility for the contest or
compromise of such Claim only if the same may be and is severed from such other
Claims (and each Indemnitee agrees to use reasonable efforts to obtain such a
severance). If Midwest elects, subject to the foregoing, to compromise or
defend any such asserted liability, it may do so at its own expense and by
counsel selected by it and reasonably satisfactory to such Indemnitee. Upon
Midwest's election to compromise or defend such asserted liability and prompt
notification to such Indemnitee of its intent to do so, such Indemnitee shall
cooperate at Midwest's expense with all reasonable requests of Midwest in
connection therewith and will provide Midwest with all information not within
the control of Midwest as is reasonably available to such Indemnitee which
Midwest may reasonably request; PROVIDED, HOWEVER, that such Indemnitee shall
not, unless otherwise required by Requirement of Law, be obligated to disclose
to Midwest or any other Person, or permit Midwest or any other Person to examine
(i) any income tax returns of the Owner Participant or (ii) any confidential
information or pricing information not generally accessible by the public
possessed by the Owner Participant (and, in the event that any such information
is made available, Midwest shall treat such information as confidential and
shall take all actions reasonably requested by such Indemnitee for purposes of
obtaining a stipulation from all parties to the related proceeding providing for
the confidential treatment of such information from all such parties). Where
Midwest, or the insurers under a policy of insurance maintained by Midwest,
undertake the defense of such Indemnitee with respect to a Claim (with counsel
reasonably satisfactory to each such Person such Indemnitee and without
reservation of rights against such Indemnitee), no additional legal fees or
expenses of such Indemnitee in connection with the defense of such Claim shall
be indemnified hereunder unless such fees or expenses were incurred at the
request of Midwest or such insurers. Notwithstanding the foregoing, an
Indemnitee may participate at its own expense in any judicial proceeding
controlled by Midwest pursuant to the preceding provisions, but only to the
extent that such party's participation does not in the reasonable opinion of
counsel to Midwest interfere with such control; PROVIDED, HOWEVER, that such
party's participation does not constitute a waiver of the indemnification
provided in this SECTION 14.1; PROVIDED, FURTHER, that if and to the extent that
(i) such Indemnitee is advised by counsel that an actual or potential conflict
of interest exists where it is advisable for such Indemnitee to be represented
by separate counsel or (ii) there is a risk that such Indemnitee may be indicted
or otherwise charged in a criminal complaint and such Indemnitee informs Midwest
that such Indemnitee desires to be represented by separate counsel, such
Indemnitee shall have the right to control its own defense of such Claim and the
reasonable fees and expenses of such defense (including, without limitation, the
reasonable fees and expenses of such separate counsel) shall be borne by
Midwest. So long as no Lease Event of Default shall have occurred and be

                                      -68-

<PAGE>

continuing, no Indemnitee shall enter into any settlement or other compromise
with respect to any Claim without the prior written consent of Midwest unless
(i) the Indemnitee waives its rights to indemnification hereunder or (ii)
Midwest has not acknowledged its indemnity obligation with respect thereto and
there is a significant risk that a default judgment will be entered against such
Indemnitee. Nothing contained in this SECTION 14.1(e) shall be deemed to require
an Indemnitee to contest any Claim or to assume responsibility for or control of
any judicial proceeding with respect thereto.

                  (f)      SUBROGATION. To the extent that a Claim indemnified
by Midwest under this SECTION 14.1 is in fact paid in full by Midwest or an
insurer under an insurance policy maintained by Midwest, Midwest (so long as no
Lease Event of Default shall have occurred and be continuing) or such insurer
shall be subrogated to the rights and remedies of the Indemnitee on whose behalf
such Claim was paid to the extent of such payment (other than rights of such
Indemnitee under insurance policies maintained at its own expense) with respect
to the transaction or event giving rise to such Claim. Should an Indemnitee
receive any refund, in whole or in part, with respect to any Claim paid by
Midwest hereunder, it shall promptly pay over to Midwest the lesser of (i) the
amount refunded reduced by the amount of any Tax incurred by reason of the
receipt or accrual of such refund and increased by the amount of any Tax (but
not in excess of the amount of such reduction) saved as a result of such payment
or (ii) the amount Midwest or any of its insurers has paid in respect of such
Claim; PROVIDED that, so long as a Material Lease Default or Lease Event of
Default shall have occurred and is continuing such amount may be held by the
Owner Lessor as security for Midwest's obligations under the Facility Lease and
the other Operative Documents.

         Any Person seeking indemnity under this SECTION 14.1 who is not a party
to this Agreement shall agree to the terms and conditions set forth in this
SECTION 14.1 as a condition to making any such claim for indemnity under this
SECTION 14.1.

         SECTION 14.2 GENERAL TAX INDEMNITY.

                  (a)      INDEMNITY. Except as provided in paragraph (b),
Midwest and Collins Holdings, jointly and severally, agree to indemnify on an

Investor, the Owner Lessor, the Trust Company in its individual capacity, the
Owner Trustee, the OP Member, the Holder Representative, the Funding LLC
Noteholders, the Lessor Noteholders and the Funding LLC, their respective
successors and assigns, the past and present partners or members of or holders
of the ownership interests in, as the case may be, the Owner Participant and the
Affiliates of each of the foregoing (each a "TAX INDEMNITEE") and to hold each
Tax Indemnitee harmless from and to defend each Tax Indemnitee against all Taxes
that are imposed upon any Tax Indemnitee, the Facility, the Facility Site, the
Undivided Interest, the Ground Interest, or any portion or Component thereof or
any interest therein, or upon

                                      -69-

         maintenance, repair, lease, condition, alteration, modification,
         restoration, refurbishing, return, purchase, sale or other disposition,
         insuring, sublease, or other use or non-use of the Facility, Undivided
         Interest, Ground Interest or the Facility Site, or any portion or
         Component thereof or any interest therein;

                           (ii)     the conduct of the business or affairs of
         Midwest at the Facility and the Facility Site;

                           (iii)    the manufacture, design, purchase,
         acceptance, rejection, delivery or condition of, or improvement to, the
         Facility, the Undivided Interest, the Ground Interest, the Facility
         Site, or any portion or Component thereof, or any interest therein;

                           (iv)     the Facility Lease, the Facility Site Lease,
         the Facility Site Sublease, any Lessor Note, any Funding LLC Note or
         any other Operative Document, the execution or delivery thereof, or the
         performance, enforcement or amendment of any terms thereof;

                           (v)      the payment or receipt of Basic Lease Rent,
         Renewal Lease Rent, Supplemental Lease Rent, any amount due on any
         Lessor Note or Funding LLC Note or any other amount payable under the
         Facility Lease; or

                           (vi)     otherwise relating to the transactions
         contemplated by the Operative Documents.

                  (b)      EXCLUDED TAXES. The indemnity provided for in
paragraph (a) above shall not extend to any of the following Taxes (the
"EXCLUDED TAXES"):

                           (i)      Taxes imposed on, based on or measured by
         gross or net income or receipts or capital or net worth (other than
         sales, use, property, ad valorem, rental, stamp, transfer, excise,
         license and value added taxes, and other than franchise tax imposed by
         the State of Illinois upon the Owner Participant, the Owner Lessor or
         their respective Affiliates under the Business Corporation Act of
         1983, as amended, or any successor legislation thereto);

                           (ii)     Taxes attributable to any period after
         expiration or other termination of the Facility Lease and, where
         required by the Facility Lease, return of the Facility to the Owner
         Lessor or its designee in accordance with the Facility Lease (or, (a)
         in the case of the Holder Representative, after the repayment of the
         Lessor Notes, or (b) in case of the Funding LLC and the Funding LLC
         Note Holders, after the sale or other disposition of the Lessor Notes
         by the Funding LLC);

                           (iii)    Taxes imposed on a Tax Indemnitee
         attributable to the gross negligence or willful misconduct of such Tax

         succession or estate, minimum, alternative minimum, preference,
         franchise, conduct of business and other similar taxes (other than
         franchise tax imposed by the State of Illinois upon the Owner
         Participant, the Owner Lessor or their respective Affiliates under the
         Business Corporation Act of 1983, as amended, or any successor
         legislation thereto);

                           (v)      Taxes imposed on a Tax Indemnitee that arise
         out of, or are caused by, any act or omission of such Tax Indemnitee
         (or any Related Party thereof) that is expressly prohibited by any
         Operative Document or by a breach by such Tax Indemnitee (or any
         Related Party thereof) of any of its representations, warranties or
         covenants under any Operative Document;

                           (vi)     Taxes arising out of, or caused by, any
         voluntary assignment, sale, transfer or other voluntary disposition, or
         any involuntary transfer or disposition resulting from a bankruptcy or
         similar proceeding for relief of debtors in which such Tax Indemnitee
         is a debtor, by (or a foreclosure by a creditor of) (A) the Owner
         Participant of any of its Beneficial Interest, (B) the Owner Lessor of
         all or any of its interest in the Facility or the Facility Site, or (C)
         the Funding LLC of any interest in the Lessor Notes or the Collateral,
         unless (i) such transfer or disposition occurs during the continuance
         of a Lease Event of Default, or (ii) such transfer or disposition is
         required under, or occurs pursuant to, the Operative Documents and the
         price paid is other than Fair Market Sales Value;

                           (vii)    Taxes arising in connection with Owner
         Participant's Liens or Owner Lessor's Liens;


                                      -71-

<PAGE>

                           (viii)   Taxes imposed on any assignee or
         successor-in-interest to a Tax Indemnitee to the extent any such Taxes
         exceed the Taxes that would have been imposed had no assignment or
         transfer taken place determined under the law as in effect on the date
         of transfer; PROVIDED that this exclusion shall not apply to the
         computation of the gross-up amounts necessary to make a payment on an
         After-Tax Basis, nor to a transferee, assignee or successor in interest
         that acquires the interest of a Tax Indemnitee pursuant to a transfer
         or disposition in connection with the exercise of remedies during the
         continuance of a Lease Event of Default;

                           (ix)     Taxes that are included as a part of

         the Funding LLC receives for its services;

                           (xi)     any U.S. federal income taxes, including
         with respect to the Owner Participant, Taxes for which Midwest is
         obligated to indemnify the Owner Participant under the Tax Indemnity
         Agreement (or which are expressly excluded from indemnification
         thereunder);

                           (xii)    other than with respect to any Funding LLC
         Note Holder, the Funding LLC, Lessor Noteholders or Holder
         Representative or any Related Party in respect of any thereof (a
         "LENDER INDEMNITEE"), Taxes resulting from the Owner Lessor not being
         treated as a grantor trust or a nonentity for federal, state or local
         income tax purposes;

                           (xiii)   Taxes attributable to the failure of any Tax
         Indemnitee to comply with certification, information, documentation,
         reporting or other similar requirements concerning the nationality,
         residence, identity, connection with the jurisdiction imposing such
         Taxes or other similar matters; PROVIDED that the foregoing exclusion
         shall only apply if such Tax Indemnitee is eligible and obligated to
         comply with such requirement and shall have been given timely written
         notice of such requirement by Midwest;

                           (xiv)    Taxes imposed on a Tax Indemnitee where the
         Tax Indemnitee's breach of its contest obligations under Section
         14.2(g) effectively precludes Midwest's ability to contest the Taxes;


                                      -72-

<PAGE>



                           (xv)     Taxes imposed on any Tax Indemnitee
         resulting from an amendment, modification, supplement or waiver to any
         Operative Document which was not requested by Midwest and as to which
         Midwest is not a party and the Tax Indemnitee (or, in the case of the
         Owner Participant, the Facility Lessor if acting at the express
         direction of the Owner Participant) is a party unless such amendment,
         modification, supplement or waiver (A) was required by applicable law
         or the Operative Documents, (B) may be necessary or appropriate to, and
         is in conformity with, any amendment, modification, supplement or
         waiver to any Operative Document agreed to by Midwest in writing, or
         (C) is made while a Lease Event of Default shall have occurred and be
         continuing;

                           (xvi)    Taxes imposed under Section 4975 of the
         Code, Section 406 of ERISA or any comparable laws of any governmental
         authority to the extent resulting from action by such Tax Indemnitee
         other than, in the case of the Owner Participant, the taking of any
         action at the request or direction of Midwest;

                           (xvii)   Taxes imposed to the extent such Taxes
         result from the Tax Indemnitee (and in the case of the Owner Lessor,
         only if acting at the written direction of the Owner Participant) being
         organized under the laws of a jurisdiction other than the United States
         or any State thereof (other than, in the case of a Lender Indemnitee,
         such Taxes which did not exist under law in effect on the date such
         Lender Indemnitee became a party to this transaction);

                           (xviii)  Any Taxes imposed on a Tax Indemnitee to the
         extent that such taxes would not have been imposed but for the
         activities of such Tax Indemnitee unrelated to the transactions
         contemplated hereby;

                           (xix)    Taxes imposed on a Tax Indemnitee in the
         nature of interest, penalties, fines and additions to tax (i) payable
         as a result of such Tax Indemnitee's failure to file, in a procedurally
         proper manner and on a timely basis, any tax reports, returns or
         statements as to which Midwest has timely notified such Tax Indemnitee
         in writing of the requirement to file, unless such failure is otherwise
         caused by the failure of Midwest to fulfill its obligations, if any,
         with respect to such return (including provision of information
         sufficient to enable such Tax Indemnitee to file such report, return or
         statement), or (ii) to the extent not attributable to or resulting from
         Taxes for which an indemnity is provided hereunder; and

                           (xx)     Taxes for as long as such Taxes are being
         contested pursuant to the contest provisions contained in Section
         14.2(g).

                  (c)      PAYMENT. Each payment required to be made by Midwest
or Collins Holdings to a Tax Indemnitee pursuant to this Section 14.2 shall be
paid either (i) when due directly to the applicable taxing authority by Midwest
if it is permitted to do so, or (ii) where direct payment is not permitted and
with respect to gross up amounts in immediately available funds to such Tax
Indemnitee by the latest of (A) 15 days following Midwest's receipt of the Tax
Indemnitee's written demand for the payment (which demand shall be accompanied
by a statement of the Tax Indemnitee describing in reasonable detail the Taxes
for which the Tax Indemnitee is demanding indemnity and the computation of such
Taxes), (B) in the case of amounts which are being contested pursuant to such
paragraph (g), 15 days following the time and in accordance with a final
determination of such contest or (C) in the case of any indemnity demand for
which Midwest has requested review and determination pursuant to paragraph (d)
below, the completion of such review and determination, but in no event later
than the date which is three Business Days prior to the date payment of such
Taxes is due. Any amount payable to Midwest pursuant to paragraph (e) or (f)
below shall be paid within 15 days after the Tax Indemnitee realizes a Tax
Benefit giving rise to a payment under paragraph (e) or receives a refund or
credit giving rise to a payment under paragraph (f), as the case may be, and
shall be accompanied by a statement of the Tax Indemnitee computing in
reasonable detail the amount of such payment. Upon the final determination of
any contest pursuant to paragraph (g) below in respect of any Taxes for which
Midwest has made a Tax Advance, the amount of Midwest's obligation under
paragraph (a) above shall be determined as if such Tax Advance had not been
made. Any obligation of Midwest under this Section 14.2 and the Tax Indemnitee's
obligation to repay the Tax Advance will be satisfied first by set off against
each other, and any difference owing by either party will be paid within 10 days
of such final determination.

                  (d)      INDEPENDENT EXAMINATION. Within 15 days after Midwest
receives any computation from the Tax Indemnitee, Midwest may request in writing
that an independent public accounting firm selected by the Tax Indemnitee and
reasonably acceptable to Midwest review and determine on a confidential basis
the amount of any indemnity payment by Midwest to the Tax Indemnitee pursuant to
this Section 14.2 or any payment by a Tax Indemnitee to Midwest pursuant to
paragraph (e) or (f) below. The Tax Indemnitee and Midwest shall cooperate with
such accounting firm and supply it with all information reasonably necessary for
the accounting firm to conduct such review and determination, PROVIDED that such
accounting firm shall agree in writing in a manner satisfactory to the Tax
Indemnitee, or Midwest, as the case may be, to maintain the confidentiality of
such information, and PROVIDED FURTHER that neither any Tax Indemnitee nor
Midwest shall be required to disclose any of its tax returns or books that such
Tax Indemnitee or Midwest, as the case may be, reasonably deems to be
confidential in

                                      -74-

connection with such verification, and the parties hereto agree that such Tax
Indemnitee, or Midwest, as the case may be, shall have sole control over the
positions taken with respect to such party's tax returns and filings. The
fees and disbursements of such accounting firm will be paid by Midwest;
PROVIDED that such fees and disbursements will be paid by the Tax Indemnitee
if the accountants determine that the present value of the total payments as
calculated by the Tax Indemnitee is more than 105 percent of the present
value of the correct payments (such present values in each case to be
determined by the Discount Rate). In the event such accounting firm
determines that such computations are incorrect, then such firm shall
determine what it believes to be the correct computations. The computations
of the accounting firm shall be final, binding and conclusive upon Midwest
and the Tax Indemnitee. The parties hereto agree that the independent public
accounting firm's sole responsibility shall be to verify the computation of
any payment pursuant to this Section 14.2 and that matters of interpretation
of this Participation Agreement or any other Operative Document are not
within the scope of the independent accountant's responsibility. Such
accounting firm shall be requested to make its determination within 30 days.

                  (e)      TAX BENEFIT. If, as the result of any Taxes paid or
indemnified against by Midwest under this Section 14.2, the aggregate Taxes
actually paid by the Tax Indemnitee in connection with such payment for any
taxable year and not subject to indemnification pursuant to this Section 14.2
are less (whether by reason of a deduction, credit, allocation or apportionment
of income or otherwise) than the amount of such Taxes that otherwise would have
been payable by such Tax Indemnitee (a "TAX BENEFIT"); then to the extent such
Tax Benefit was not taken into account in determining the amount of
indemnification payable by Midwest under paragraph (a) above and provided no
Lease Event of Default shall have occurred and be continuing (in which event the
payment provided under this Section 14.2(e) shall be deferred until the Lease
Event of Default has been cured), such Tax Indemnitee shall pay to Midwest the
lesser of (A) (y) the amount of such Tax Benefit, plus (z) an amount equal to
any United States federal, state or local income tax benefit resulting to the
Tax Indemnitee from the payment under clause (y) above and this clause (z)
(determined using the same assumptions as set forth in the second sentence under
the definition of After-Tax Basis) and (B) the amount of the indemnity paid
pursuant to this Section 14.2 giving rise to such Tax Benefit, provided that any
excess of the amount described in clause (A) over the amount described in clause
(B) shall be carried forward and applied to reduce pro tanto any subsequent
obligations of Midwest to make payment to such Tax Indemnitee pursuant to this
Section 14.2. If it is subsequently determined that the Tax Indemnitee was not
entitled to such Tax Benefit, the portion of such Tax Benefit that is required
to be repaid or recaptured will be treated as Taxes for which Midwest must
indemnify the Tax Indemnitee pursuant to this Section 14.2 without regard to
paragraph (b) hereof.


                                      -75-

<PAGE>

                  (f)      REFUND. If a Tax Indemnitee obtains a refund or
credit or would have received such refund or credit but for a counterclaim or
other claim not indemnified by Midwest hereunder against which such refund or
credit has not been applied (an "offset refund or credit") of all or part of any
Taxes paid, reimbursed or advanced by Midwest pursuant to this Section 14.2, the
Tax Indemnitee shall pay to Midwest within 15 days of such receipt, or in the
case of an offset refund or credit, within 15 days of the resolution of such
contest (x) the amount of such refund or credit (net of any Tax payable by the
Tax Indemnitee as a result of the receipt or accrual of such refund or credit)
plus (y) an amount equal to any Tax Benefit realized by such Tax Indemnitee by
reason of such payment to Midwest (determined using the same assumptions as set
forth in the second sentence under the definition of After-Tax Basis), PROVIDED
that (A) if at the time such payment is due to Midwest a Lease Event of Default
shall have occurred and be continuing, such amount shall not be payable until
such Lease Event of Default has been cured, and (B) the amount payable to
Midwest pursuant to this sentence shall not exceed the amount of the indemnity
payment in respect of such refunded or credited Taxes that was made by Midwest
(and such excess shall be carried forward and applied to reduce pro tanto any
subsequent obligations of Midwest to make payments to such Tax Indemnitee
pursuant to this Section 14.2). If it is subsequently determined that the Tax
Indemnitee was not entitled to such refund or credit, the portion of such refund
or credit that is required to be repaid or recaptured will be treated as Taxes
for which Midwest must indemnify the Tax Indemnitee pursuant to this Section
14.2 without regard to paragraph (b) hereof. If, in connection with a refund or
credit of all or part of any Taxes paid, reimbursed or advanced by Midwest
pursuant to this Section 14.2, a Tax Indemnitee receives an amount representing
interest on such refund or credit, the Tax Indemnitee shall pay to Midwest
within 15 days (1) the amount of such interest that shall be fairly attributable
to such Taxes paid, reimbursed or advanced by Midwest prior to the receipt of
such refund or credit (net of Taxes payable in respect of the receipt or accrual
of such interest) and (2) any Tax savings resulting from payments made by the
Tax Indemnitee under this Section 14.2.

                  (g)      CONTEST.

                           (i)      NOTICE OF CONTEST. If a written claim is
         made by any taxing authority against a Tax Indemnitee for any Taxes
         with respect to which Midwest may be required to indemnify against
         hereunder (a "TAX CLAIM"), such Tax Indemnitee shall give Midwest
         written notice of such Tax Claim promptly after its receipt, and shall
         furnish Midwest with copies of such Tax Claim and all other writings
         received from the taxing authority to the extent relating to such
         claim, provided that failure so to notify Midwest shall not relieve
         Midwest of any obligation to indemnify the Tax Indemnitee hereunder
         except to the extent such failure effectively precludes Midwest from
         contesting such Tax. The Tax Indemnitee shall

                                      -76-

<PAGE>



         not pay such Tax Claim until at least 30 days after providing Midwest
         with such written notice, unless (a) the Tax Indemnitee is required to
         do so by law or regulation and (b) in the written notice described
         above, the Tax Indemnitee has notified Midwest of such requirement.

                           (ii)     CONTROL OF CONTEST. Subject to subsection
         (g)(iii) below, Midwest will be entitled to contest (acting through
         counsel selected by Midwest and reasonably satisfactory to the Tax
         Indemnitee), and control the contest of, any Tax Claim if (i) such Tax
         Claim may be segregated procedurally and contested independently from
         tax claims for which Midwest is not obligated to indemnify the Tax
         Indemnitee, PROVIDED that if the Tax Indemnitee reasonably determines
         at any time that permitting Midwest to conduct or continue to conduct
         such contest could have material adverse business or other consequences
         to such Tax Indemnitee, such Tax Indemnitee shall have the right to
         control or reassert control over such contest, or (ii) the Tax
         Indemnitee requests that Midwest control such contest; PROVIDED that in
         the case of any such contest pursuant to (i) or (ii) Midwest shall use
         all reasonable efforts to contest such Tax Claim in its own name, and
         PROVIDED FURTHER that such contest shall be at Midwest's sole cost and
         expense. Midwest shall consult in good faith with the Tax Indemnitee
         and its counsel and shall provide the Tax Indemnitee with copies of any
         reports or claims issued by the relevant auditing agent or taxing
         authority, but the decisions regarding what actions to be taken shall
         be made by Midwest in its sole judgment.

                            In the case of all other Tax Claims, the Tax
         Indemnitee will contest the Tax Claim at Midwest's expense if Midwest
         shall request that the Tax be contested (in accordance with subsection
         (g)(iii) below), and the following rules shall apply with respect to
         such contest:

                                       (1)  the Tax Indemnitee will control the
         contest of such Tax Claim in good faith (acting through counsel
         selected by the Tax Indemnitee and reasonably satisfactory to Midwest),

                                       (2)  at Midwest's written request, if
         payment is made to the applicable taxing authority, the Tax Indemnitee
         shall use all reasonable efforts to obtain a refund thereof in
         appropriate administrative or judicial proceedings,

                                       (3) the Tax Indemnitee conducting such
         contest shall consult with and keep reasonably informed Midwest and its
         designated counsel with respect to such Tax Claim and shall consider
         and

                                      -77-

<PAGE>

         consult in good faith with Midwest regarding any request (a) to resist
         payment of Taxes if practical and (b) not to pay such Taxes except
         under protest if protest is necessary and proper, but the decision
         regarding what actions to be taken shall be made by the Tax Indemnitee
         in its sole judgment.

                                       (4) Notwithstanding paragraph (3),
         above, the Tax Indemnitee shall not otherwise settle, compromise or
         abandon such contest without Midwest's prior written consent except as
         provided in paragraph (g)(iv) below.

                           (iii)    CONDITIONS OF CONTEST. Notwithstanding the
         foregoing, no contest with respect to a Tax Claim will be required or
         permitted pursuant to this Section 14.2, and Midwest shall be required
         to pay the applicable Taxes without contest, unless:

                                       (1) within 30 days after notice by the
         Tax Indemnitee to Midwest of such Tax Claim, Midwest shall request in
         writing to the Tax Indemnitee that such Tax Claim be contested,
         provided that if a shorter period is required for taking action with
         respect to such Tax Claim and the Tax Indemnitee notifies Midwest of
         such requirement, Midwest shall use reasonable best efforts to request
         such contest within such shorter period, and such Tax Indemnitee shall
         take no action for as long as it is legally able to do so,

                                       (2) no Lease Event of Default has
         occurred and is continuing,

                                       (3) there is no risk of sale, forfeiture
         or loss of, or the creation of a Lien (other than a Permitted Lien) on
         the Facility, Owner Lessor's or Owner Participant's interest in the
         Facility, the Facility Site, the Undivided Interest, the Ground
         Interest or any portion or Component thereof or any interest therein
         as a result of such Tax Claim; PROVIDED that this clause (3) shall not
         apply if Midwest shall have posted and maintained a bond or otherwise
         provided security for Midwest's obligations under Section 14.2
         satisfactory to the Tax Indemnitee in its reasonable discretion, or
         the Tax is fully paid in either manner specified in clause (5) below,

                                       (4) there is no risk of imposition of
         any criminal penalties,


                                      -78-

<PAGE>

                                       (5) if such contest involves payment of
         such Tax, Midwest will either advance to the Tax Indemnitee on an
         interest-free basis and with no after-tax cost to such Tax Indemnitee
         (a "TAX ADVANCE") or pay such Tax Indemnitee the amount payable by
         Midwest pursuant to Section 14.2(a) above with respect to such Tax, and
         such Tax Indemnitee shall promptly pay to Midwest any net Tax Benefit
         recognized which results from any imputed interest deduction arising
         from such interest free Tax Advance plus any net Tax Benefit recognized
         which result from making any such payment.

                                       (6) Midwest agrees to pay (and pays on
         demand) and with no after-tax cost to such Tax Indemnitee all
         reasonable costs, losses and expenses incurred by the Tax Indemnitee
         in connection with the contest of such claim (including, without
         limitation, all reasonable legal, accounting and investigatory fees
         and disbursements),

                                       (7) the Tax Indemnitee has been provided
         at Midwest's sole expense with an opinion, reasonably acceptable to
         such Tax Indemnitee, of independent tax counsel of recognized standing
         selected by Midwest and reasonably acceptable to the Tax Indemnitee to
         the effect that there is a Reasonable Basis for contesting such Tax
         Claim,

                                       (8) in the case of a judicial appeal,
         no appeal to the U.S. Supreme Court shall be required of the Tax
         Indemnitee or shall be permitted by Midwest.

                                       (9) In the case of a judicial contest,
         Midwest shall have delivered to the Tax Indemnitee a written
         acknowledgment of its liability under this Section 14.2 for such Taxes,
         PROVIDED, HOWEVER, that Midwest shall not be bound by its
         acknowledgment of liability if the contest is resolved on the basis of
         a written decision of the adjudicator that clearly indicates the basis
         for the conclusion that Midwest has no liability under this Section
         14.2 with respect to such Tax, unless Midwest's conduct of the contest
         has materially prejudiced the Tax Indemnitee.

                           (iv)     WAIVER OF INDEMNIFICATION. Notwithstanding
         anything to the contrary contained in this Section 14.2, the Tax
         Indemnitee at any time may elect to decline to take any action or any
         further action with respect to a Tax Claim and may in its sole
         discretion settle or compromise any contest with respect to such Tax
         Claim without Midwest's consent if the Tax Indemnitee:


                                      -79-

<PAGE>

                                       (1)  waives its right to any indemnity
         payment by Midwest pursuant to this Section 14.2 in respect of such Tax
         Claim (and any other claim for Taxes with respect to any other taxable
         year the contest of which is effectively precluded by the Tax
         Indemnitee's declination to take action with respect to the Tax
         Claim), and

                                       (2) promptly repays to Midwest any Tax
         Advance and any amount paid to such Tax Indemnitee under Section 14.2
        (a) above in respect of such Taxes.

         Except as provided in the preceding sentence, any such waiver shall be
without prejudice to the rights of the Tax Indemnitee with respect to any other
Tax Claim.

                           (h)      REPORTS.

                                    (i)      If any report, statement or return
         is required to be filed by a Tax Indemnitee with respect to any Tax
         that is subject to indemnification under this Section 14.2, Midwest
         will (1) notify the Tax Indemnitee in writing of such requirement not
         later than 30 days prior to the date such report, statement or return
         is required to be filed (determined without regard to extensions) and
         (2) either (y) if permitted by applicable law, prepare such report,
         statement or return for filing by Midwest in such manner as will show
         the ownership of the Facility by the Owner Lessor for United States
         federal, state and local income tax purposes (if applicable), send a
         copy of such report, statement or return to the Tax Indemnitee and
         timely file such report, statement or return with the appropriate
         taxing authority, or (z) if so directed by the Tax Indemnitee or in any
         event if practicable and if the return to be filed reflects only
         information in respect of the transactions contemplated by the
         Operative Documents, prepare and furnish to such Tax Indemnitee not
         later than 30 days prior to the date such report, statement or return
         is required to be filed (determined without regard to extensions) a
         proposed form of such report, statement or return for filing by the Tax
         Indemnitee.

                                    (ii)     Each of the Tax Indemnitee or
         Midwest, as the case may be, will timely provide the other, at
         Midwest's expense, with all information in its possession that the
         other party may reasonably require and request to satisfy its
         obligations under this paragraph (h), but only if and to the extent
         that such Tax Indemnitee is legally entitled to furnish such
         information.


                                      -80-
<PAGE>

                                    (i)      NON-PARTIES. If a Tax Indemnitee is
         not a party to this Agreement, Midwest may require such Tax Indemnitee
         to agree in writing, in a form reasonably acceptable to Midwest, to the
         terms of this Section 14 (to the extent applicable to such Tax
         Indemnitee) prior to making any payment to such Tax Indemnitee under
         this Section.

SECTION XV           MIDWEST'S AND COLLINS HOLDINGS' RIGHT OF QUIET ENJOYMENT

         Each party to this Agreement acknowledges notice of, and consents in
all respects to, the terms of the Facility Lease, the Facility Sublease, the
Facility Site Sublease and the Facility Site Sub-sublease and expressly,
severally and as to its own actions only, agrees that, so long as no Lease Event
of Default has occurred and is continuing, neither it nor any party acting by,
through or under such party shall take or cause to be taken any action contrary
to Collins Holdings' rights under the Facility Lease and the Facility Site
Sublease and Midwest's rights under the Facility Sublease and the Facility Site
Sub-sublease, including the right to possession, use and quiet enjoyment of the
Undivided Interest and the Ground Interest.

SECTION XVI          SUPPLEMENTAL FINANCING OF IMPROVEMENTS; OPTIONAL
                     REFINANCINGS

         SECTION 16.1      FINANCING IMPROVEMENTS.

         Upon the written request of Midwest delivered at least 90 days prior to
any proposed financing of the cost of any Required or Non-Severable Improvement,
the Owner Lessor and the Holder Representative agree to cooperate with Midwest
to (a) issue Additional Lessor Notes by the Owner Lessor to finance such
Improvement which will rank pari passu with the Lessor Notes then outstanding;
and (b) execute and deliver an amendment to the Facility Lease to reflect the
adjustments required by clause (v) below; PROVIDED, HOWEVER, that the Owner
Participant shall have been given the opportunity, but shall have no
obligation, to provide all or part of the funds required to finance the Owner
Lessor's Percentage of any such Improvement by making an Additional Equity
Investment in such amount, if any, as it may determine in its sole discretion.
Midwest shall have no obligation to accept and the Owner Participant shall not
be obligated to provide such Additional Equity Investment. The obligation to
finance such Improvement through the issuance of Additional Lessor Notes (any
financing of Improvements through the issuance of such Additional Lessor Notes
being called a "SUPPLEMENTAL FINANCING") is subject to the limitations on
incurrence of additional Indebtedness set forth in the Operative Documents and
the following additional conditions:

                                    (i)      there shall be no more than one
         such financing in any calendar year;

                                      -81-

<PAGE>


                                    (ii)     Improvements shall be made in
         compliance with the Operative Documents;

                                    (iii)    such Improvement is a Required
         Improvement;

                                    (iv)     subject to Section 2.03 of the
         Lessor Loan Agreement, the Additional Lessor Notes shall have a final
         maturity date no later than the expiration date of the Basic Lease Term
         or any Renewal Term then in effect or already elected by Collins
         Holdings as instructed by Midwest and will be fully repaid out of
         additional Basic Lease Rent or Renewal Rent and Termination Value as
         adjusted pursuant to the Operative Documents;

                                    (v)      appropriate adjustments to Basic
         Lease Rent and Termination Value (determined without regard to any tax
         benefits associated with such Improvements, unless the Owner
         Participant is making an Additional Equity Investment) shall also be
         made to protect the Owner Participant's Expected Return;

                                    (vi)     Midwest shall have paid, on an
         After-Tax Basis, all reasonable out-of-pocket costs and expenses of
         the Lease Financing Parties, including the reasonable fees and expenses
         of counsel to the Owner Participant, the Owner Lessor, the Owner
         Trustee and the Holder Representative, in each case to the extent
         incurred in connection with any financing or refinancing pursuant to
         this SECTION 16;

                                    (vii)    no Lease Event of Default shall
         have occurred and be continuing unless the Improvements to be
         constructed with the proceeds of the Additional Lessor Notes shall cure
         such Lease Event of Default, and any such Improvements shall be made in
         compliance with the Operative Documents;

                                    (viii)   the sum of (y) the principal amount
         of such Additional Lessor Notes and (z) the principal amount of all

         pursuant to the Other Facility Leases, is not less than $20 million and
         not greater than 100% of the cost of the Improvements being financed;
         PROVIDED that the sum of (I) the outstanding balance of the Lessor
         Notes and (II) all comparable lessor notes issued and outstanding of
         the Other Owner Lessors under the respective lessor loan agreements to
         which such Other Owner

         Lessors are party never exceeds (x) 90% of the lesser of (1) the fair
         market value of the Facility taking into account such Improvements, as
         determined pursuant to the Appraisal Procedure, and (2) the sum of (t)
         the Purchase Price, (u) the comparable purchase price for each of the
         Other Undivided Interests and (v) the cost of the Improvement being
         financed;

                                    (ix)     the Owner Participant shall have
         received a favorable opinion reasonably satisfactory to it from Hunton
         & Williams, or from nationally recognized tax counsel selected by the
         Owner Participant and reasonably acceptable to Midwest, to the effect
         that such financing would not result in any material indemnified, or
         any unindemnified, incremental tax risk to the Owner Participant;

                                    (x)      the Owner Participant shall not
         suffer any material adverse accounting effects under GAAP as a result
         of providing such additional financing;

                                    (xi)     the cost of the Improvement,
         together with the cost of all previous Improvements financed with
         Additional Lessor Notes is not greater than 25% of the sum of (x) the
         Purchase Price and (y) the comparable purchase price for each of the
         Other Undivided Interests; unless the Facility Lessee shall have
         received confirmation that giving effect to the financing in connection
         with such Improvement, the Funding LLC Debt rating will not fall below
         BBB- or Baa3 from S&P and Moody's, respectively; and

                                    (xii)    Midwest shall have made or
         delivered such representations, warranties, covenants, opinions or
         certificates as the Owner Participant may reasonably request.

                                    (xiii)   such Additional Lessor Notes are
         issued pursuant to and in accordance with SECTION 2.03 of the Lessor
         Loan Agreement and Midwest and Collins Holdings shall have delivered
         such certificates, reports and other documents and shall have taken all
         other actions which are required to be delivered or taken by them
         pursuant to SECTION 2.03 of the Lessor Loan Agreement.

         Notwithstanding the prior provision dealing with the financing of
Improvements through the Facility Lease, Midwest shall at all times have the
right to finance Improvements to the Facility other than through the Facility
Lease; PROVIDED that Improvements may only be financed other than through the
Facility Lease if such financing would not result in any Lien on the Facility or
the Facility Land and shall be subject to the limita-


                                      -83-

<PAGE>

tions on incurrence of additional Indebtedness contained in the other Operative
Documents; PROVIDED FURTHER, that Required Improvements and Non-Severable
Improvements shall automatically, upon being affixed to the Facility, become the
property of the Owner Lessor and subject to the Facility Lease.

         SECTION 16.2 OPTIONAL REFINANCING OF LESSOR LOAN. Midwest will have the
right, exercisable on no more than three occasions, for as long as no Material
Lease Default or Lease Event of Default shall have occurred and be continuing,
to request the Owner Lessor, and the Owner Lessor shall reasonably consider and
shall not unreasonably refuse, to refund or refinance the Lessor Notes, in the
public or private market, in whole but not in part, through the issuance of new
notes to the public (notes issued in such refinancing, the "NEW LESSOR NOTES"),
to the Funding LLC, to a pass through trust or to such other funding vehicles as
may be used at that time or to any other party that is not the Facility Lessee,
the Facility Sublessee or any Affiliate thereof; PROVIDED that any refinancing
under this SECTION 16.2 shall also be subject to satisfaction of the following
conditions:

                                    (i)      the Owner Lessor shall be able to
         issue and sell the New Lessor Notes in an amount adequate to accomplish
         such refunding or refinancing;

                                    (ii)     the Owner Participant shall receive
         an opinion reasonably satisfactory to it from Hunton & Williams or from
         nationally recognized tax counsel selected by the Owner Participant and
         reasonably acceptable to the Facility Lessee, to the effect that such
         refinancing (as opposed to the right to request such refinancing)
         would not result in any material indemnified or any unindemnified
         incremental tax risk to the Owner Participant (including tax risks
         relating to the classification of the Lessor Notes as qualified
         nonrecourse indebtedness; provided, however, that absent a change in
         law or judicial, administrative or legislative interpretation thereof
         after the Closing Date, there would not be incremental tax risk with
         respect to the allocation of interest expense for foreign tax credit
         purposes from a refinancing consummated in accordance with the
         provisions set forth below);

                                    (iii)    all documentation in connection
         with such refinancing shall be reasonably satisfactory to the Owner
         Lessor, the Owner Trustee, and the Owner Participant and conditions set
         forth therein shall be met;


                                      -84-

                                    (iv)     other than for the first such
         refinancing, the Owner Participant shall be entitled to a consent fee
         of $25,000 in connection therewith;

                                    (v)      the refinancing shall not result in
         any other material adverse effect on the rights or interests of the
         Owner Lessor or the Owner Participant;

                                    (vi)     New Lessor Notes shall be issued in
         compliance with Section 467 of the Code and any proposed, temporary, or
         final regulation thereunder, in each case as modified and in effect on
         the date of such issuance.

                                    (vii)    all necessary authorizations,
         approvals and consents in connection with such refinancing shall have
         been obtained from each Person whose authorization, approval or consent
         is necessary to consummate such refinancing with respect to the
         Facility Lessee, the Owner Lessor and the Holder Representative, and
         such authorizations, approvals and consents shall be in full force and
         effect on the closing date of such refinancing;

                                    (viii)   if (i) the principal amount of the
         New Lessor Notes exceeds that of the Lessor Notes existing on the
         refinancing date or (ii) the final maturity date of the New Lessor
         Notes is different from that of the existing Lessor Notes, the
         consummation of the transactions contemplated by the refinancing shall
         not cause the Owner Participant to account for the transactions
         contemplated by the Operative Documents as other than a "leveraged
         lease" under FAS 13;

                                    (ix)     all payment dates for principal and
         interest payments on the New Lessor Notes shall become Rent Payment
         Dates;

                                    (x)      on the closing date of such
         refinancing, each of the Facility Lessee, the Owner Lessor and the
         Holder Representative shall have executed and delivered all
         appropriate supplements to the Operative Documents that are necessary
         to consummate such refinancing, in form and substance reasonably
         satisfactory to the Owner Lessor and the Holder Representative;

                                    (xi)     each of the Owner Lessor, the Owner
         Participant and the Holder Representative shall have received an
         opinion

                                      -85-

<PAGE>



         of counsel for the Facility Lessee on such matters as they may
         reasonably request and in form and substance reasonably satisfactory to
         the Owner Participant and the Holder Representative;

                                    (xii)    Midwest and Collins Holdings shall
         have delivered such certificates, reports and other documents and shall
         have taken all other actions which are required to be delivered or
         taken by them pursuant to SECTION 2.03 of the Lessor Loan Agreement;

                                    (xiii)   each of the Owner Lessor, the Owner
         Participant and the Holder Representative shall have received from the
         Facility Lessee a certificate dated the date of the issuance of the New
         Lessor Notes executed on behalf of the Facility Lessee by an Authorized
         Officer thereof stating that all conditions precedent to the issuance
         of such New Lessor Notes have been satisfied or waived;

                                    (xiv)    the consummation of any transaction
         contemplated by such refinancing shall not violate any Requirements of
         Law except to the extent that such non-compliance with the Requirements
         of Law would not have a material adverse effect on the Owner Lessor.

                                    (xv)     the New Lessor Notes shall have a
         final maturity date no later than six months after the stated maturity
         date of the Initial Lessor Notes as set forth in Section 2.02(a) of the
         Lessor Loan Agreement and the weighted average life to maturity of the
         New Lessor Notes shall not vary from the remaining weighted average
         life-to-maturity of the Lessor Notes (immediately prior to such
         refinancing) by more than six months; and

                                    (xvi)    the principal amount of the New
         Lessor Notes shall not exceed by more than 5 percent the remaining
         principal amount of the Lessor Notes (immediately prior to such
         refinancing).

                                    (xvii)   the New Lessor Notes shall satisfy
         the requirements of Temp. Treas. Reg. Section 1.861 - 10T(b)(2)(iii),
         (iv) and (v) and not be excluded by reason of Temp. Treas. Reg.
         Section 1.861 - 10T(b)(4).

         SECTION 16.3 LEVEL 7 REFINANCING. At any time the Facility Lessee is
notified in writing by the Owner Lessor or the Holder Representative that the
Lessor Loan Rate will increase to Level 7 as a result of the occurrence of a
Level 7 Event, the Facility Lessee shall, subject to the conditions set forth in
SECTION 16.2 above, arrange for the refinancing

                                      -86-

<PAGE>



of the Lessor Notes. The Facility Lessee and the Owner Lessor shall make
corresponding changes to Basic Lease Rent and the Termination Value in
accordance with the rent adjustment provisions set forth in SECTION 3 of the
Facility Lease.

         SECTION 16.4 COOPERATION. The Owner Participant will cooperate with and
reasonably assist Midwest in connection with any refinancing and/or assumption
of the Lessor Notes, so long as such refinancing is in accordance with the terms
of the Operative Documents. The Owner Participant will execute such agreements
and documents as may be necessary with respect to any such refinancing and will
instruct the Owner Lessor to act accordingly. Nothing contained in this SECTION
16 shall limit Midwest's right to request a refinancing in accordance with
SECTION 16.2, above, refinance the Lessor Notes and to make corresponding
changes to Basic Lease Rent and the Termination Value in accordance with the
rent adjustment provisions set forth in SECTION 3 of the Facility Lease.

         SECTION 16.5 LETTER OF CREDIT. Contemporaneously with any refinancing
of the Lessor Notes pursuant to Section 16.2 or 16.3 effected at a time when the
Midwest Letter of Credit or RCE Letter of Credit is outstanding or Midwest LC
Reimbursement Obligations or RCE LC Reimbursement Obligations are outstanding,
(a) Midwest shall cause any such outstanding Midwest Letter of Credit to be
cancelled or otherwise terminated and all such Midwest LC Reimbursement
Obligations to be paid in full and (b) the Owner Lessor shall cause any such
outstanding RCE Letter of Credit to be cancelled or otherwise terminated and
all such RCE LC Reimbursement Obligations to be paid in full.

SECTION XVII               PRE-CLOSING ADJUSTMENTS TO BASIC LEASE RENT AND
                           TERMINATION VALUE

                           (a)      Prior to or on the Closing Date, Basic Lease
Rent and Termination Values (and the allocations of Basic Lease Rent and 467
Fixed Rent) shall be adjusted, either upward or downward, in accordance with the
Facility Lease:

                                    (i)      at Midwest's option, to re-optimize
         the Lessor Loan; and

                                    (ii)     to reflect any changes in the
         Pricing Assumptions, including, without limitation, (x) the initial
         interest rate on any of the Lessor Notes which is different from the
         applicable Lessor Loan Rate set forth in the Pricing Assumptions, (y)
         an increase in the Maximum Transaction Costs amount assumed in the
         Pricing Assumptions, unless Midwest has elected to pay such increase,
         and (z) a Closing Date other than the Scheduled Closing Date; and

                                    (iii)    at the request of Midwest or the
         Owner Participant to reflect any enactment, promulgation, release or

                                      -87-

<PAGE>

         adoption of, amendment to or change in the Code, Treasury Regulations,
         Revenue Rulings or Revenue Procedures ("TAX LAW CHANGE") enacted prior
         to the Closing;

PROVIDED that if any adjustment required by this paragraph would cause (x) on an
After-Tax Basis the present value of Basic Lease Rent as a percentage of the
Purchase Price discounted at 6% to increase by more than 100 basis points or (y)
the total Basic Lease Rent to increase by more than 2.0%, Midwest shall not be
obligated to close the Overall Transaction.

                           (b)      Any adjustment pursuant to this SECTION 17
shall be calculated (A) so as not to negatively affect the Owner Participant's
Expected Return through the Basic Lease Term and (B) to maintain operating lease
treatment for Midwest; PROVIDED, HOWEVER, that to the extent it is not possible
as the transaction is then structured to achieve both (A) and (B), the Owner
Trust, the Owner Participant and Midwest shall work in good faith to restructure
the transaction in a manner which would achieve both results; and PROVIDED,
FURTHER, that to the extent consistent with preserving both such objectives, all
adjustments shall at the option of Midwest be calculated to (x) minimize the
average annual Basic Lease Rent over the Basic Lease Term for Midwest's GAAP
accounting purposes and/or (y) minimize, to the extent possible, the present
value to Midwest of the Basic Lease Rent; and PROVIDED, FURTHER, that to the
extent that any adjustment pursuant to this SECTION 17 fails to maintain
operating lease treatment for Midwest, Midwest shall not be obligated to close
the Overall Transaction. Adjustments will be made using the same method of
computation, assumptions and pricing constraints originally used (other than
those that have changed as the result of the event giving rise to the
adjustment) in the calculation of the Basic Lease Rent (and the allocation of
Basic Lease Rent and 467 Fixed Rent) and corresponding adjustments to
Termination Values will be made. Adjustments may not result in a book loss to
the Owner Participant in the year of adjustment and will be computed by the
Owner Participant (or the OP Guarantor if prior to the Closing Date) based upon
the Tax Assumptions and the Pricing Assumptions used to calculate the Basic
Lease Rent and Termination Values and shall be subject to verification procedure
set forth in the Facility Lease.

SECTION XVIII              RIGHT OF FIRST REFUSAL; RIGHT OF FIRST OFFER.

         SECTION 18.1 RIGHT OF FIRST OFFER. In the event the Owner Participant
desires to sell, lease, convey or otherwise transfer some or all of its
Beneficial Interest other than to an Affiliate of the Owner Participant (other
than in connection with the exercise of remedies following a Lease Event of
Default) prior to the expiration of the Facility Lease Term, the Owner
Participant must first offer to sell such Beneficial Interest to the Facility
Lessee on the terms and conditions set forth in this SECTION 18.1. Such offer
shall be made to the Facility Lessee in the form of a proposed term sheet, which
proposed term

                                      -88-

<PAGE>

sheet shall include an outline of the price and of the terms, conditions and
provisions upon which the Owner Participant would be willing to transfer such
Beneficial Interest or any part thereof. The Facility Lessee will thereafter
have the right within a period of forty-five (45) days from and after the
receipt by the Facility Lessee of such proposed term sheet to notify the Owner
Participant of its intent to exercise its right to purchase hereunder. If the
Facility Lessee elects to exercise the right provided in the preceding sentence,
it shall within 60 days of such notice purchase, and the Owner Participant shall
sell, the Beneficial Interest on the same terms and conditions as the offer
giving rise to such right. If the Facility Lessee does not give such notice to
the Owner Participant within the forty-five (45) day period or does not purchase
the Beneficial Interest within 60 days of such notice, the Owner Participant
will be free to so sell, lease, convey or otherwise transfer such Beneficial
Interest, or a portion thereof, at a price no less than the price set forth in
the proposed term sheet and on terms and conditions, taken as a whole, that,
other than in an immaterial respect, are no less favorable to the Owner
Participant than the terms and conditions set forth in the proposed term sheet,
unless the failure to purchase the Beneficial Interest within 60 days is
attributable to the Owner Participant. In the event that the terms or conditions
are revised in any way that the price is reduced or any of the other terms and
conditions thereof, taken as a whole change the agreement for sale, lease,
conveyance or transfer such that the terms and conditions of any such subsequent
transaction are less favorable, other than in an immaterial respect, to the
Owner Participant, the Owner Participant must again comply with the notice and
acceptance provisions of this SECTION 18.1. It is understood and agreed among
the parties hereto that the transaction contemplated by this SECTION 18.1 shall
not effect a merger of the Facility Lessee's ownership interest in the Facility
and the Facility Site with the Owner Lessor's Interest.

         SECTION 18.2 RIGHT OF FIRST REFUSAL. In the event the Owner Participant
desires to sell, lease, convey or otherwise transfer some or all of its
Beneficial Interest or cause the Owner Lessor to sell, lease, convey or
otherwise transfer its Owner Lessor's Interest at any time within three years
after expiration or termination other than to an Affiliate of the Owner
Participant (other than pursuant to SECTION 13 and 14 of the Facility Lease) of
the Facility Lease to any Person other than the Facility Lessee or an Affiliate
thereof, the Facility Lessee shall have the right, unless such sale, lease,
conveyance or transfer is in connection with the exercise of remedies upon a
Lease Event of Default, to purchase, lease or otherwise acquire such interest on
the terms and conditions set forth in the bid that the Owner Participant intends
to accept. The Owner Participant shall give the Facility Lessee prompt written
notice of all bona fide offers that have been received from any other Person to
purchase or acquire the Owner Lessor's Interest or Owner Participant's
Beneficial Interest or any part of either during such three-year period
following the expiration or termination of the Facility Lease, and which offers
it wishes to accept, together with a full and complete statement of the price
and all of the material terms, conditions and provisions contained in such
offers. The Facility Lessee shall thereafter

                                      -89-

<PAGE>

have the right within a period of forty-five (45) days from and after the
receipt by the Facility Lessee of such notice to notify the Owner Participant of
its intent to exercise its rights of first refusal. If the Facility Lessee
elects to exercise the right provided in the preceding sentence, it shall within
60 days of such notice purchase, and the Owner Participant shall sell, the
Beneficial Interest on the same terms and conditions as the offer giving rise to
such right. If the Facility Lessee does not give such notice to the Owner
Participant within the forty-five (45) day period or does not purchase the
Beneficial Interest within sixty (60) days of such notice, the Owner Participant
shall be free to proceed under the terms and conditions as set forth in its
irrevocable notice to the Facility Lessee, unless the failure to purchase the
Beneficial Interest within sixty (60) days is attributable to the Owner
Participant. In the event that the terms or conditions are revised in any way
that changes the agreement for sale, lease, conveyance or transfer such that the
terms and conditions thereof, other than in immaterial respects, are less
favorable to the Owner Participant (including any reduction in price or a change
in the terms of payment thereof in a manner that is beneficial to the potential
purchaser), the Owner Participant must again comply with the notice and
acceptance provisions of this SECTION 18.2. In connection with the Facility
Lessee's exercise of the right of first refusal pursuant to this SECTION 18.2
with respect to the Owner Lessor's Interest, the Ground Interest shall be
conveyed to the Facility Lessee.

SECTION XIX           SPECIAL LESSEE TRANSFER

         In the case of a Regulatory Event of Loss or Burdensome Buyout Event
under the Facility Lease, the Facility Lessee (or its designee), so long as the
Facility Lessee shall remain liable under the Facility Lease to pay Basic Lease
Rent and all other payments under the Facility Lease, upon not less than 30
days' written notice to the Owner Participant and the Holder Representative, on
the applicable Termination Date, may purchase the Owner Participant's Beneficial
Interest, or, in the case of a Burdensome Buyout Event, the membership interest
in the Owner Participant, and keep the Facility Lease (and the Lessor Loan) in
place; PROVIDED, that (i) the Owner Participant shall not suffer any detriment
(including tax or book consequences) from such purchase (as compared to that
which would have resulted had the Facility Lessee terminated the Facility Lease
and purchased the Owner Lessor's Interest), (ii) the Facility Lessee satisfies
the transferee requirements contained in SECTION 12.1 hereof applicable to
transfers by the Owner Participant, if applicable and (iii) the Facility Lessee
pays all expenses incurred by the other Lease Financing Parties in connection
therewith. If the Facility Lessee chooses to purchase the Owner Participant's
Beneficial Interest or the membership interest in the Owner Participant, as the
case may be, pursuant to the preceding sentence, on the applicable Termination
Date, the Facility Lessee (or its designee) shall pay to the Owner Participant
or to the Equity Investor, as the case may be, the Special Lessee Transfer
Amount determined as of such date, plus all amounts due and payable to the Owner

                                      -90-

<PAGE>

Participant or Equity Investor, as the case may be, on such date under the
Operative Documents.

         Concurrently with the payment of all sums required to be paid pursuant
to this SECTION 19 (or on such later date of transfer of the Owner Participant's
Beneficial Interest or membership interest in the Owner Participant, as the case
may be, in accordance with clause (ii) below) (i) the Facility Lessee shall
cease to have any liability to the Owner Participant with respect to the
Operative Documents, except for obligations (including those under SECTIONS 14.1
and 14.2 hereof and the Tax Indemnity Agreement) surviving pursuant to the
express terms of any Operative Document or which have otherwise accrued but not
been paid as of such date and (ii) the Owner Participant or the Equity Investor,
as the case may be, will transfer (by an appropriate instrument of transfer in
form and substance reasonably satisfactory to the Owner Lessor and prepared and
recorded at the Facility Lessee's expense) the Owner Participant's Beneficial
Interest or membership interest in the Owner Participant, as the case may be, to
the Facility Lessee (or its designee); PROVIDED, HOWEVER, that if the Lessor
Notes are outstanding, such transfer shall not be made to the Facility Lessee,
but shall be made to the Facility Lessee's designee promptly upon the Facility
Lessee's designation of such designee and such designee will agree not to
transfer the Owner Participant's Beneficial Interest or the membership interest
in the Owner Participant, as the case may be, to the Facility Lessee for as long
as the Lessor Notes are outstanding. The Owner Participant or Equity Investor,
as the case may be, shall make any transfer under this SECTION 19 on an "as is,"
"where is" basis, without warranty other than as to the absence of Owner
Lessor's Liens and Owner Participant's Liens on the Owner Participant's
Beneficial Interest or the membership interest in the Owner Participant, as the
case may be. It is understood and agreed among the parties hereto that the
transaction contemplated by this SECTION 19 shall not effect a merger of the
Facility Lessee's leasehold interest in the Facility and subleasehold interest
in the Facility Site with the Owner Lessor's Interest. The Facility Lessee will
pay all reasonable costs and expenses of the Lease Financing Parties in
connection with any transfer pursuant to this SECTION 19. Subsequent to such

SECTION XXI           AGREEMENT WITH RESPECT TO COLLINS HOLDINGS

         Each of the parties hereto agrees that it shall not institute against,
or solicit or join any other Person in instituting against, Collins Holdings any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding,
or any other proceeding under any federal or state bankruptcy or similar law,
for one year and a day after the payment in full of all amounts due by and
satisfaction of all obligations of, Collins Holdings under the Facility Lease.

SECTION XXII          MISCELLANEOUS

         SECTION 22.1 CONSENTS. The Owner Participant covenants and agrees that
it shall not unreasonably withhold its consent to any consent requested of the
Owner Lessor under the terms of the Operative Documents that by its terms is not
to be unreasonably withheld by the Owner Lessor.

         SECTION 22.2 SUCCESSOR OWNER LESSOR. The parties hereto agree that the
transfer or assignment pursuant to the terms of the Trust Agreement by the Owner
Lessor to a successor Owner Lessor, pursuant to the trust created thereunder,
will not violate the terms of any Operative Document.

         SECTION 22.3 BANKRUPTCY OF TRUST ESTATE. If (i) all or any part of the
Trust Estate becomes the property of a debtor subject to the reorganization
provisions of Title 11 of the United States Code, as amended from time to time,
(ii) pursuant to such reorganization provisions the Owner Participant is
required, by reason of the Owner Participant being held to have recourse
liability to the debtor or the trustee of the debtor directly or indirectly, to
make payment on account of any amount payable as principal or interest on the
Lessor Notes, and (iii) the Holder Representative actually receives any Excess
Amount, as defined below, which reflects any payment by the Owner Participant on
account of clause (ii) above, the Holder Representative shall promptly refund to
the Owner Participant such Excess Amount. For purposes of this SECTION 22.3,
"EXCESS AMOUNT" means the amount by which such payment exceeds the amount which
would have been received by the Holder Representative if the Owner Participant
had not become subject to the recourse liability referred to in clause (ii)
above. Nothing contained in this SECTION 22.3 shall prevent the Holder
Representative from enforcing any personal recourse obligations (and retaining
the proceeds thereof) of the Owner Participant as contemplated by this Agreement
(other than referred to in clause (ii)).

         SECTION 22.4 AMENDMENTS AND WAIVERS. No term, covenant, agreement or
condition of this Agreement may be terminated, amended or compliance therewith
waived (either generally or in a particular instance, retroactively or
prospectively) except by an instrument or instruments in writing, executed by
each party hereto.

Midwest as a result of any transfer while a Material Lease Default or a Lease
Event of Default is continuing, in which case Midwest shall be obligated to pay
such costs.

                           (d)      Upon any transfer to a Member Transferee
specified in clause (a)(i)(B) of this SECTION 22.18 and compliance with all of
the other provisions of this SECTION 22.18, (i) the Member Transferee shall, to
the extent of the Membership Interest conveyed to the Member Transferee, be
deemed an "OP Member" for purposes of this SECTION 22.18 and the Person
executing the guaranty pursuant to such clause (a)(i)(B) shall be deemed a
"Guarantor" for all purposes and each reference in this Agreement and each other
Operative Document to the "Guarantor" shall thereafter be deemed to include such
Member Transferee or the Person executing such guaranty, as the case may be, to
the extent of the obligations expressly transferred to the Member Transferee and
guaranteed by such Person, for all purposes and (ii) the existing Guarantor
shall be released from all obligations under its Owner Participant Guaranty to
the extent such obligations are expressly guaranteed by the Member Transferee or
such Affiliate; PROVIDED, HOWEVER, that in no event shall any such transfer
waive or release the existing Guarantor from any liability existing immediately
prior to or occurring simultaneously with such transfer. Except as expressly
provided in the immediately preceding sentence, no transfer of any Membership
Interest shall effect the obligations of the existing Guarantor under the Owner
Participant Guaranty or any other Guarantor under its Guaranty.

                           (e)      Notwithstanding anything herein to the
contrary, any transfer of Membership Interest pursuant to this SECTION 22.18
shall be subject to Midwest's right of


                                     -101-

first offer and right of first refusal set forth in SECTION 18.1 and 18.2,
respectfully, to the same extent as if such transfer were a transfer by the
Owner Participant of its Beneficial Interest.

         SECTION 22.19 ISSUER DOWNGRADE EVENT. Each of the Midwest LC Issuer and
the RCE LC Issuer hereby covenants and agrees that it will promptly furnish to
Midwest, Collins Holdings and the Owner Participant a written notice of any
downgrade of its rating.

(b) is "a United States person" within the meaning of section 7701(a)(30) of the
Code; and (c) neither the Transferee nor any of its Affiliates is a Competitor
of, or engaged in material litigation with, Midwest, or any Affiliate of
Midwest.(1)

SECTION 7.        OPINION OF COUNSEL

----------------
      (1)   The representation in Section 6(c) hereof shall be replaced with the
            following representation if the Transferee or any of its Affiliates
            is a Competitor of, or engaged in material litigation with, Midwest
            and the criteria contained in the following representation shall
            have been met: The Transferee represents and warrants that (i) the
            Transferee is an entity involved in making passive investments such
            as the Transferor's contemplated investment in this transaction,
            (ii) such Transferee has in place procedures which shall be
            reasonably acceptable to Midwest to prevent its Affiliate that is a
            Competitor from acquiring confidential information relating to such
            passive investments and agrees in writing with Midwest to maintain
            and abide by such procedures, and (iii) neither such Transferee nor
            any Affiliate thereof is an entity that is (x) actively involved in
            the generation of electricity in Mid-American Interconnected Network

            thereto, or (y) on the List of Competitors, attached as Exhibit SS
            to the Participation Agreement, which may, from time to time, but no
            more often than once per year, be modified by Midwest, and shall
            contain a list of up to six entities (including Affiliates) which
            Midwest reasonably believes in its good faith judgment are
            Competitors of Midwest or its Affiliates.


<PAGE>

SECTION 7.        OPINION OF COUNSEL

      Prior to, or on the date hereof, the Transferor shall have delivered to
Midwest, the Owner Trustee and, so long as the Lessor Notes are outstanding, the
Holder Representative an opinion of counsel relating to this Agreement. Such
opinion and counsel shall be reasonably satisfactory to each recipient thereof,
to the effect that this Agreement is a legal, valid and binding obligation of,
and is enforceable against, each party hereto and (ii) to the effect that all
regulatory approvals required in connection with the transfer contemplated by
this Agreement or necessary to assume the Transferor's obligations under the
Operative Documents shall have been obtained and that the proposed transfer of
the Beneficial Interest will not require registration the Securities Act.
