the "Act"), has been enacted by the Indiana General Assembly.

     The Act provides that the Issuer is authorized to issue bonds and loan the
proceeds thereof for the purpose of financing the costs of acquisition,
construction, or installation of industrial development projects, including
land, machinery, equipment, or any combination thereof, for the public purpose
of promoting opportunities for gainful employment and business opportunities
which will be of public benefit to the health, safety, morals, and general
welfare of the State of Indiana and its citizens.

of $14,345,000 (the "Series 1996 Bonds") pursuant to the Trust Indenture dated
as of June l, 1996 (the "Indenture") between the Issuer and Old National Trust
Company, as Trustee (the "Trustee"), and intends to lend the proceeds of the
Series 1996 Bonds pursuant to the provisions of this Loan Agreement to the
Company to finance an industrial development project (as deemed in the Act).

of the proceeds of the Series 1996 Bonds and further provides (i) for the
Company's repayment obligation to be evidenced by the Company's First Mortgage
Note, Series 1996 (the "Series 1996 Note") in substantially the form attached
hereto as "Exhibit B," and (ii) for such loan and the Series 1996 Note to be
secured by the mortgage and security interest herein provided.

will be payable out of (i) the payments to be made by the Company on the Series
1996 Note and any other Notes issued hereunder or (ii) Bond proceeds and other
proceeds required to be deposited in the Redemption Account as deemed in the
Indenture.

further notice thereof except as may be specifically required by this Section
3.2.

contingency, event or cause whatsoever, and irrespective (without limitation) of
whether the Company's Mortgaged Property or any part thereof is defective or
nonexistent, or whether the Company's revenues are sufficient to make such
payments, and notwithstanding any damage to, or loss, theft or destruction of,
the Mortgaged Property or any part thereof, expiration of this Mortgage, any
failure of consideration or frustration of purpose, the taking by eminent domain
or otherwise of title to or of the right of temporary use of, all or any part of



                                      -17-



the Mortgaged Property, legal curtailment of the Company's use thereof, or
whether with or without the approval of the Issuer, any change in the tax or
other laws of the United States of America, the State of Indiana, or any
political subdivision of either thereof, any change in the Issuer's legal
organization or status, or any default of the Issuer hereunder, and regardless
of the invalidity of any portion of this Mortgage; and the Company hereby waives
the provisions of any statute or other law now or hereafter in effect impairing
or conflicting with any of its obligations, covenants or agreements under this
Mortgage or which releases or purports to release the Company therefrom. Nothing
in this Mortgage shall be construed as a waiver by the Company of any rights or
claims the Company may have against the Issuer under this Mortgage or otherwise,
but any recovery upon such rights and claims shall be had from the Issuer
separately, it being the intent of this Mortgage that the Company shall be
unconditionally and absolutely obligated without right of set-off or abatement,
to perform fully all of its obligations, agreements and covenants under this
Mortgage for the benefit of the holders of the Bonds.

     It is understood and agreed that all payments made by Company pursuant to
Section 3.2 hereof and the Notes are pledged to Trustee pursuant to the granting
clauses of the Indenture. Company assents to such pledge, and hereby agrees
that, as to Trustee, its obligation to make such payments shall be absolute and
shall not be subject to any defense or any right of set-off, counterclaim or
recoupment arising out of any breach by Issuer or Trustee of any obligation to
Company, whether hereunder or otherwise, or out of any indebtedness or liability
at any time owing to Company by Issuer. Issuer hereby directs Company and
Company hereby agrees to pay to Trustee at its principal office all said amounts
payable by Company pursuant to Section 3.2 hereof and the Notes.

     It is understood and agreed that Company shall be obligated to continue to
pay the amounts specified herein and in the Notes whether or not the Project is
damaged, destroyed or taken in condemnation and that there shall be no abatement
of any such payments and other charges by reason thereof.

     As security for payment of the Loan Payments, the Company agrees to cause
IDEM to directly transfer the Gross Revenues of the Project to the Trustee for
deposit in the Revenue Fund. The Gross Revenues and any additional amounts paid
by the Company, if necessary, shall be used by the Trustee to pay, throughout
the term of the Loan, the Loan Payments, in such lawful money of the United
States of America as at the time of payment shall be legal tender for the
payment of public and private debts.

     All transfers of Gross Revenues shall be made to the Trustee at the
designated office of the Trustee in Evansville, Indiana, or at such other
location as shall be designated in writing by the Trustee to the Company and
IDEM.

     Section 3.3.  MAINTENANCE OF LIEN; RECORDING.  The Company will, at its
expense, take all necessary action to maintain and preserve the lien and
security interest of this Mortgage as valid and perfected first liens and
security interests, subject only to Permitted Encumbrances, so long as any Note,
or other indebtedness or obligation secured hereby is outstanding. The 



                                      -18-



Company will, forthwith after the execution and delivery of this Mortgage and 
thereafter from time to time, cause this Mortgage and any financing

manner and in such places as may be required by law in order to publish 
notice of, perfect, maintain the priority of, and fully to protect the lien 
and security interest hereof upon, and the title of the Company to, the 
Mortgaged Property; and from time to time will perform or cause to be 
performed any other act as provided by law and will execute or cause to be 
executed any and all continuation statements and further instruments that may 
be requested by the Issuer, the Original Purchaser or Trustee for such 
publication, perfection, maintenance of priority, and protection. The Company 
will pay or cause to be paid all filing, registration and recording fees 
incident to such filing, registration and recording, and all expenses 
incident to the preparation, execution and acknowledgment of such instruments 
of further assurance, and all federal or state fees and other similar fees, 
duties, imposts, assessments and charges arising out of or in connection with 
the execution and delivery of this Mortgage and such instruments of further 
assurance.

     Section 3.4.  FURTHER ASSURANCES; AFTER-ACQUIRED PROPERTY.  (a) The Company
will do, execute, acknowledge and deliver, or cause to be done, executed,
acknowledged and delivered, all such further acts, deeds, conveyances,

Purchaser or Trustee reasonably may require for the better assuring, conveying,
mortgaging, assigning and confirming unto the Issuer and the Trustee all and
singular the Mortgaged Property as now or hereafter constituted, within ten (10)
days of any request of the Issuer, Trustee or Original Purchaser.

     (b)  Without the need for any request by the Issuer, the Original Purchaser
or the Trustee, all right, title and interest of the Company in and to all
improvements, betterment, renewals, substitutions and replacements of, the
Mortgaged Property or any part thereof, hereafter constructed or acquired by the
Company, and all additions and accessions thereto and proceeds thereof
immediately upon such construction or acquisition, without any further
mortgaging, conveyance or assignment, shall become and be part of the Mortgaged
Property and shall be subject to the lien and security interest of this Mortgage
and Parity Instruments as fully and completely and with the same effect as
though now owned by the Company, but at any and all times the Company will
execute and deliver to the Issuer and the Original Purchaser any and all such
further assurances, mortgages, conveyances or assignments therefor and other
instruments with respect thereto as the Issuer or the Original Purchaser may
reasonably require for the purpose of expressly and specifically subjecting the
same to the lien and security interest of this Mortgage.

     Section 3.5.  CORPORATE EXISTENCE.  (a) So long as debt is outstanding
under the Public Debt Instruments, not later than thirty (30) days prior to the

existence, including without limitation dissolution, merger, consolidation, or
reorganization.


 
                                      -19-



          (b)  When debt is no longer outstanding under the Public Debt
     Instruments, not later than thirty (30) days prior to the effective date

     all of its assets, and will not consolidate with or merge into another
     corporation, or permit one or more other corporations to consolidate or
     merge with it; provided, that the Company may, without violating the
     agreement contained in this Section, consolidate or merge with another
     corporation, permit one or more other corporations to consolidate or merge
     into it, or transfer to another corporation organized under the laws of one
     of the states of the United States all or substantially all of its assets
     as an entirety and thereafter dissolve provided (i) the surviving,

     the laws of one of the states of the United States, and remains or becomes
     qualified to do business in the State, (ii) such corporation assumes in
     writing all of the obligations of the Company herein, including the

     the Company's public debt is not rated after such merger or consolidation,
     such corporation shall have a net worth equal to or higher than the net
     worth of the Company on the date of delivery of the Series 1996 Note.

     Section 3.6.  FINANCIAL REPORTING.  (a) The Company agrees to keep at all
times books and records and accounts in which full, true and correct entries
will be made of all dealings or transactions in relation to the business and
affairs of the Company in accordance with generally accepted accounting
principles consistently applied.

          (b)  The Company shall furnish to the Trustee and to the Bondholders:

               (i)  for as long as any of the Public Debt Instruments are in
          effect, copies of all information filed with the Securities and
          Exchange Commission as well as all compliance certificates, reports
          and information required to be delivered to the trustees under the
          Public Debt Instruments, as and when the same are provided to such
          trustees; and

               (ii) at such time as the Company is no longer a reporting company
          under the 1934 Act, at all times not covered by (i) above, (A) within
          45 days after the end of each fiscal quarter of each calendar year of
          the Company, unaudited quarterly financial statements of the Company,
          attested to by the chief financial officer of the Company; and (B)

          selected by the Company which shall be a nationally recognized Big Six
          accounting firm or otherwise reasonably acceptable to the Trustee and
          the



                                      -20-



          Original Purchaser and accompanied by an opinion of such accountants
          unqualified as to scope; and

               (iii)     at such time as the Company is no longer a reporting
          company under the 1934 Act, an authorized officer the Company shall
          certify annually that he has obtained no knowledge of the occurrence
          of any material adverse change in the financial condition of the
          Company.

     In addition, the Company shall furnish such additional information as the
Issuer, the Trustee or the Original Purchaser may reasonably request concerning
the Company, insofar as such information may be provided without violation of
the provisions of the 1934 Act, in order to enable the Issuer, the Trustee or
the Original Purchaser to determine whether the covenants, terms and provisions
of this Loan Agreement have been complied with by the Company and for that
purpose all pertinent financial books, documents and vouchers relating to its
business affairs and properties shall at all times upon reasonable prior notice
during regular business hours be open to the inspection of such persons or their
accountants or other agents (who may make copies of all or any part thereof) as
shall from time to time be designated by the Issuer, the Trustee or the Original
Purchaser. The party making any such request shall bear the expenses incurred in
connection with honoring the request.

     Without limiting the foregoing, the Company will permit the Issuer, the
Trustee and the Original Purchaser (or such persons as the Original Purchaser
may designate) to visit and inspect, at the expense of the Issuer, the Trustee
or the Original Purchaser, any of the properties of the Company and to discuss
the affairs, fiances and accounts of the Company with its officers and
independent accountants, in so far as such information may be provided without
violation of the provisions of the 1934 Act, all upon reasonable prior notice
and at such reasonable times during normal business hours and as often as the
Trustee or the Original Purchaser may reasonably desire.  Access to and
inspections of the Project and Project Sites during the period of construction
of the Project shall be governed solely by Section 3.25 of this Loan Agreement.

     Section 3.7.  TAXES, CHARGES AND ASSESSMENTS.  The Company covenants and
agrees, subject to the provisions of Section 3.10 hereof, to pay when the same
shall become due or payable:

          (a)  all taxes and charges on account of the ownership, use, occupancy
     or operation of the Mortgaged Property, including but not limited to all
     sales, use, occupancy, real and personal property taxes, all permit and
     inspection fees, occupation and license fees and all water, gas, electric
     light, power or other utility charges assessed or charged on or against
     such Mortgaged Property or on account of the Company's use or occupancy
     thereof or the activities conducted thereon or therein; and

          (b)  all taxes, assessments and impositions, general and special,
     ordinary and extraordinary, of every name and kind, which shall be taxed,
     levied, imposed or assessed upon all or any part of such Mortgaged
     Property, or the interest of the Company therein.


 
                                       -21-



     If under applicable law any such tax, charge, fee, rate, imposition or
assessment may at the option of the taxpayer be paid in installments, the
Company may exercise such option.

     Nothing contained herein shall be deemed to constitute an admission by the
Company that the Company is liable for any tax, charge, fee, rate, imposition or
assessment.

     Section 3.8.  LIENS. Subject to the provisions of Section 3.10 hereof, the
Company will not allow to exist and will not create or permit to be created or
exist and will, at its cost and expense, promptly discharge all liens, security
interests, encroachments, encumbrances and charges on the Mortgaged Property or
any part thereof that are not Permitted Encumbrances.

     Section 3.9.  COMPLIANCE WITH ORDERS, ORDINANCES, ETC.  Subject to the
provisions of Section 3.10 hereof, the Company will, at its sole cost and
expense, comply with all present and future laws, ordinances, orders, decrees,
rules, regulations and requirements of every duly constituted governmental
authority, commission and court and the officers thereof of which it has notice,
and the failure to comply with which would materially and adversely affect the
Mortgaged Property or the use, occupancy or condition thereof.

     Section 3.10.  PERMITTED CONTESTS; WAIVER BY REQUISITE BONDHOLDERS.  The
Company shall not be required to pay any tax, charge, fee, rate, imposition or
assessment required to be paid under Section 3.7 hereof, nor to remove any lien,
security interest, encroachment, encumbrance or charge required to be removed
under Section 3.8 hereof, nor to comply with any law, ordinance, order, decree,
rule, regulation or requirement referred to in Section 3.9 hereof, so long as
the Company shall in good faith and at its cost and expense, and after providing
the Issuer and the Original Purchaser with written notice, contest the amount or
validity thereof, or take other appropriate action with respect thereto, in an
appropriate manner or by appropriate proceedings, which shall operate during the
pendency thereof to prevent (a) the collection of or other realization upon the
tax, charge, assessment, lien, security interest or encumbrance so contested and
(b) the sale, forfeiture or loss of the Mortgaged Property or any part thereof
to satisfy the same; and provided that no such contest or action shall subject
the Issuer or the Trustee to any liability unless the Company properly
indemnifies the Issuer or the Trustee, as the case may be. While any such
matters are pending, the Company shall have the right to pay, remove or cause to
be discharged or marked exempt the tax, charge, assessment, lien, security
interest or encumbrance being contested.  Each such contest shall be promptly
prosecuted to final conclusion or settlement, and the Company will pay, and save
the Issuer and the Trustee harmless against, all losses, judgments, decrees and
costs (including attorneys' fees and expenses in connection therewith) and will,
promptly after the final determination or settlement of such contest or action,
pay and discharge the amounts which shall be levied, assessed or imposed or
determined to be payable thereon, together with all penalties, fines, interests,
costs and expenses thereon or in connection therewith. During the pendency of
each such contest, the Company shall maintain appropriate reserves for any
contested liability, which reserves will be maintained with the Trustee as
required in order for such liens to be considered Permitted Encumbrances.



                                      -22-



     Section 3. 11.  REPAIRS, MAINTENANCE AND ALTERATIONS.  The Company will at

reasonable wear and tear excepted, and in as reasonably safe condition as its
operation will permit and will make all necessary repairs thereto, interior and
exterior, structural and non-structural, ordinary as well as extraordinary and
foreseen as well as unforeseen, and all necessary replacements or renewals.

     The Company shall have the right from time to time at its own cost and
expense to make additions, alterations and changes, whether structural or non-
structural (hereinafter collectively referred to as "alterations") in or to the

changes shall not diminish the value of the Mortgaged Property in any material
respect, except such changes or modifications as required by IDEM or the
provisions of the IDEM Contract.

     Section 3.12.  COMPANY DUTIES UNDER INDENTURE.  The Company agrees to
perform all obligations under the Indenture to be performed by the Company and

     damage from aircraft, smoke and uniform standard extended coverage and

     the State of Indiana. Such insurance shall be in such amount as shall be
     approved by the Requisite Bondholders. No policy of insurance shall be so
     written that the proceeds thereof will produce less than the minimum
     coverage required by the preceding sentence, by reason of co-insurance
     provisions or otherwise, without the prior consent thereto in writing by
     the Requisite Bondholders.

          (b)  Comprehensive general public liability insurance for injuries to
     persons and/or property, in limits not less than, and with deductibles not
     greater than, that approved by the Requisite Bondholders.

          (c)  Workmen's compensation insurance respecting all employees of the
     Company in such amount as is customarily carried by like organizations
     engaged in like activities of comparable size and liability exposure;
     provided that the Company may be self-insured with respect to all or any
     part of its liabilit0y for workmen's compensation.

     to repair, rebuild or replace the damaged property or (iii) six months.

          (e)  Professional liability or malpractice insurance in limits not
     less than that which is customarily carried by like organizations engaged

financially sound and responsible insurance companies qualified or authorized
under the laws of the State of Indiana to assume the risks covered by such
policy, (ii) name the Trustee, the Company, and the Issuer as assureds, as their
respective interests may appear, and (iii) provide that such policy shall not be
cancelled without at least 30 days prior written notice to each assured named
therein. With respect to the insurance required by subsection (a) above, the
policy or policies shall provide that whenever the Net Proceeds resulting from a
claim exceed $100,000, such Net Proceeds shall be payable to the Trustee, and if
such Net Proceeds are equal to or less than $100,000, such Net Proceeds shall be
payable directly to the Company.  As to the insurance required by subsections
(b) through (e) above, the Net Proceeds shall be payable to or for the benefit

reasonable prior written notice the Company will permit the Trustee to visit the
offices of the Company and inspect the Company's insurance records including all
policies of insurance maintained pursuant to this Section and to make copies of
all or any part thereof.

     Any of the foregoing insurance maintained by the Company pursuant hereto
may be evidenced by one or more blanket insurance policies covering the
Mortgaged Property and other property or assets of the Company.

     Section 3.14.  TRUSTEE'S RIGHT TO PERFORM COMPANY'S COVENANTS; ADVANCES.

with respect thereto pursuant to Section 3. 10 hereof) the Trustee, upon not
less than 5 days prior written notice to the Company, may (but shall not be
obligated to) remedy such default for the account of the Company and make
advances for that purpose. No such performance or advance shall operate to
release the



                                      -24-



Company from any such default, and any sums so advanced by the
Trustee shall be due and payable by the Company on demand and shall bear
interest at the Default Rate from the date of the advance until repaid.

     Section 3.15.  INDEMNITY.  Subject to the provisions of the second to last

claims, demands and judgments of any nature arising from or relating to:

          (a)  The acceptance or administration of the Indenture or the trusts
     thereunder or the performance of the Issuer's duties thereunder, except

     performance of any obligation related to the issuance, sale, or delivery of
     (or failure to issue, sell or deliver) the Bonds under this Loan Agreement
     or the Indenture, or any other agreement executed by or on behalf of the
     Issuer (provided that nothing in this clause should be construed to
     indemnify or release the Issuer from any liability which it would otherwise
     have had arising from the intentional misrepresentation or wilful
     misconduct on the part of the Issuer other than as contemplated in this
     Loan Agreement); and



                                      -25-



          (i)  The authorization, issuance, sale, trading, redemption, or
     servicing of the Bonds and the provision of any information or
     certification furnished by the Company in connection therewith, concerning
     the Bonds, the Project or the Company.

The foregoing indemnification shall survive the termination of this Loan
Agreement and the payment or satisfaction of the indebtedness and obligations
secured hereby except as provided in Section 10.8 hereof.

     Notwithstanding the foregoing, the obligation to indemnify, defend and hold
harmless the State, acting by and through IDEM, for liability arising from the
performance of the IDEM Contract, shall be limited to such liability caused by
any act or omission of the Company and/or its subcontractors under the IDA
Contract, if any.

     The foregoing shall not be construed to prohibit the Company from pursuing
its remedies against either the Issuer or the Trustee for damages to the Company
resulting from personal injury or property damage caused by the intentional
misrepresentation or willful misconduct of either the Issuer or the Trustee or
the negligence or willful misconduct of the Trustee or breach of the Indenture
by the Trustee.

     Section 3.16.  ISSUANCE OF SUBSTITUTE NOTES.  Upon the surrender of any
Note or upon the receipt of a written notice of loss, theft, destruction or

thereof a new Note dated the date of the Note being surrendered or the original
date of the Note in the case of any lost, stolen, destroyed or mutilated Note,
but with appropriate notations thereon to reflect payments of principal and
interest thereon; provided, however, that there shall never be outstanding at
any one time more than one Note of any one series. Prior to execution and
delivery of any such replacement Note the Company shall be indemnified to its
reasonable satisfaction by the person seeking such replacement Note.

     Section 3.17.  PAYMENT OF EXPENSES OF ISSUANCE OF SERIES 1996 BONDS.  The
Company agrees to be liable for and pay for any recording expenses, trustee's
acceptance fees, commitment fees, escrow and title insurance costs, legal fees,
printing expenses and other fees and expenses incurred or to be incurred by or

in a form acceptable to the Issuer, Trustee and Original Purchaser in the
aggregate amount equal to the purchase price of the land, building improvements
and fixtures constituting the Project, issued by a title insurance company
satisfactory to the Issuer, the Trustee and the Original Purchaser, insuring
that the Trustee has 



                                      -26-



a first mortgage lien on the Mortgaged Property, subject only to Permitted 
Encumbrances, if any.  Any Net Proceeds received from such policy or policies 
shall be deposited in the Redemption Account for the redemption of Bonds in 
order to effect a prepayment of a portion of the Note as provided in Section 
5.2 hereof.

     Section 3.19.  FUNDING OF INDENTURE FUNDS; INVESTMENTS.  The Issuer shall

the manner specified in Article ffl of the Indenture, and the Trustee shall
deposit such proceeds in the manner specified in such Article. Further, the
Company shall deposit with the Trustee an amount sufficient, when added to the
amount already deposited in the Debt Service Fund, to cause the Debt Service
Reserve Fund to be Fully Funded.

     The Trustee is hereby authorized, upon the direction of the Company, to
trade with itself in the purchase and sale of securities for such investments.
The Trustee shall not be liable or responsible for any loss resulting from any
such investment. All such investments shall be held by or under the control of

     Section 3.22.  COMPLETION OF PROJECT.

          (a)  Company agrees that:

               (i)  It will make, execute, acknowledge and deliver any
          contracts, orders, receipts, writings and instructions with any other
          persons, fins or corporations and in general do all things which may
          be requisite or proper, all for completing the Project.

               (ii) It will construct the Project in accordance with the final
          plans and specifications approved by IDEM, will substantially complete

          endorsement to the mortgagee title insurance policy or policies
          required by Section 3.18 hereof, reflecting completion of the Project.

     In the event the moneys in the Construction Fund should not be sufficient
to pay in full the costs to be paid therefrom, the Company agrees, for the
benefit of the Issuer and the Bondholders and in order to fulfill the purposes
of the Act, to complete the Project and to pay that portion of the costs
therefor as may be in excess of the moneys available therefor in such

                           [MISSING ORIGINAL PAGE 29]



                                      -28-



          (ii) Notwithstanding the foregoing, but subject to receipt of prior
     written consent from the Issuer and the Original Purchaser, the Company may
     sell all or any portion of any Project Site that is no longer needed to
     perform its obligations under the IDEM Contract at such Project Site. All
     proceeds received by the Company (net of reasonable selling expenses
     actually incurred by the Company, not exceeding five percent (5%) of such
     proceeds) as a result of any such action shall be paid to the Trustee for
     deposit to the Redemption Account for redemption of Bonds in order to
     effect prepayment of a portion of the Note in accordance with Section 5.2
     hereof.  If the Company purchases or otherwise acquires an alternative
     Project Site to replace an existing Project Site, the alternative Project
     Site shall become Mortgaged Property.  Following the execution, delivery
     and recording by the Company of such documents as may be necessary to
     subject such alternative Project Site to the lien of this Mortgage, subject
     only to Permitted Encumbrances, the Company may, subject to receipt of
     prior written consent from the Issuer and the Original Purchaser, sell the
     replaced Project Site, and all proceeds received upon such sale shall be
     applied as follows: (1) an amount equal to the excess of such proceeds over
     the price paid by the Company to acquire the alternative Project Site shall
     be paid to the Trustee for deposit to the Redemption Account for redemption
     of Bonds in order to effect prepayment of a portion of the Note in
     accordance with Section 5.2, and (2) the remainder shall be released to the
     Company. Upon paying over the proceeds of sale in accordance with this
     clause (ii), the lien of this Mortgage against the Project Site so sold
     shall be released. No release effected under the provisions of this Section
     3.23 shall, except to the extent provided in Section 5.4 hereof, entitle
     the Company to any abatement or diminution of the payments to be made
     hereunder.

     Section 3.24.  SUBSTITUTION AND REMOVAL OF EQUIPMENT.  Except as provided
in this Section and Section 3.23 hereof, Equipment comprising part of the
Mortgaged Property shall remain in or near the buildings comprising the
Mortgaged Property and on the site thereof. The Company may from time to time
substitute Equipment in the Mortgaged Property if the Equipment so substituted
shall be of equivalent utility to that replaced, and if such substitution is
made in accordance with the terms of the IDEM Contract. Such substituted
Equipment shall become a part of the Mortgaged Property and be included under
the terms of the Mortgage, and the replaced Equipment shall become the property
of the Company free and clear of any claims of the Issuer, the Trustee or the
Bondholders therein or thereto, upon payment to the Trustee, for deposit to the
Redemption Account for the redemption of Bonds in order to effect the prepayment
of a portion of the Note in accordance with Section 5.2, of (1) if the replaced
Equipment is sold by the Company, the amount by which the proceeds of such sale
(net of reasonable selling expenses actually incurred by the Company) exceed the
purchase price paid by the Company for the substituted Equipment, or (2) if the
Equipment is not sold by the Company, the amount by which the fair market value
of the replaced Equipment exceeds the purchase price paid by the Company for the
substituted Equipment.  Any such substituted Equipment with an aggregate fair
market value in excess of $100,000 shall be identified in writing by the Company
to the Trustee, and the Original Purchaser and shall require the consent of the
Original Purchaser.



                                      -29-



     The Trustee, at the request of the Company, shall release from the lien of
the Mortgage any Equipment comprising part of the Mortgaged Property without
substitution therefor so long as such property is no longer used by or useful to
the Company in the performance of its obligations under the IDEM Contract
(whether by reason of changed techniques, obsolescence, depreciation or
otherwise), provided that the Company shall pay to the Trustee for deposit in
the Redemption Account (i) if such Equipment is sold, all proceeds from the sale
of such Equipment (net of reasonable selling expenses actually incurred by the
Company) or (ii) if such Equipment is not sold the fair market value, if any, of
the Equipment and such amount shall be used for redemption of the Bonds in order
to effect prepayment of a portion of the Notes as provided in Section 5.2
hereof. Upon such payment, the Equipment shall be free and clear of any claims
of the Issuer, the Trustee or the Bondholders. This provision shall not entitle
the Company to any abatement or diminution of the payments payable hereunder.

     The Issuer and Company agree to execute and deliver such documents (if any)
as the Issuer or Company or Trustee may reasonably request in connection with
any action taken by the Issuer or Company under this Section.

     Section 3.25.  RIGHT OF ACCESS TO THE MORTGAGED PROPERTY.  The Company
shall allow the Original Purchaser and its agents at all reasonable times during
development and construction of the Project, entry and free access to the
Project, and to inspect all work done, labor performed and materials furnished
on or about the Project. Without limiting the generality of the foregoing,
Purchaser shall have the right to have materials and work tested at the
Company's expense by third parties selected by the Original Purchaser if
reasonably deemed necessary by the Original Purchaser. Company agrees that any
inspection by the Original Purchaser of the improvements is for the purpose of
protecting the security of the Original Purchaser. No such inspection shall be a
representation by the Original Purchaser that there has been strict compliance
by the general contractor or any subcontractor with the approved plans and
specifications or that the construction is free from faulty materials or
workmanship, nor shall any inspection by the Original Purchaser constitute
approval of any certification given to the Original Purchaser or relieve any
person making such certification from responsibility therefor.

     Section 3.27.  RESERVED.

     Section 3.28.  SECURITY AGREEMENT.  (a) With respect to those items
referenced in the Granting Clauses in which a security interest may be created
under Article 9 of the Uniform Commercial Code, as adopted and in effect in the
State (herein sometimes referred to as the "Collateral"), this Loan Agreement is
hereby made and declared to be a security agreement encumbering each and every
item of such property comprising a part of the Collateral, in compliance with
the provisions of the Uniform Commercial Code as adopted and in effect in the
State. The Company hereby authorizes the Issuer, and the Trustee as the assignee
of the Issuer, to execute and file, without necessity for the execution thereof
by the Company, any financing statements, continuation statements, or other
instruments or documents that the Issuer or the 



                                      -30-


Trustee may deem necessary or desirable to perfect and maintain the lien of 
this security agreement upon the Collateral and all parts thereof. The 
Company and Issuer agree that the filing of any such financing statement(s) 
in the records normally having to do with personal property shall not in any 
way affect the agreement of the parties hereto that all Equipment used in 
connection with the production of income from the Mortgaged Property or 
adapted for use therein or which is described or reflected in this Loan 
Agreement is, and at all times and for all purposes and in all proceedings, 
both legal and equitable, shall be regarded as part of the real estate 
conveyed hereby regardless of whether any such item is physically attached to 
the improvements or that serial numbers are used for the better 
identification of certain items capable of being thus identified in an 
exhibit hereto, or as any such item is referred to or reflected in any such 
financing statement(s) so filed at any time.

          (b)  The mention in any such financing statement(s) of the rights in
     and to (i) the proceeds of any insurance policy, (ii) any award in
     condemnation or eminent domain proceedings for a taking or for loss of
     value, or (iii) Company's interest as landlord in any present or future
     lease or sublease or rights to income growing out of the use and/or
     occupancy of the Mortgaged Property, whether pursuant to a tenant lease of
     space or otherwise, shall not in any way alter any of the rights of the
     Issuer as determined by this Loan Agreement or affect the priority of the
     Issuer's security interest granted hereby or by any other recorded
     document, it being understood and agreed that such mention in such
     financing statement(s) is solely for the protection of the Issuer in the
     event any court shall at any time hold with respect to the foregoing
     clauses (i) to (iii) of this Section 3.28(b) that notice of the Issuer's
     priority of interest, to be effective against a particular class of
     persons, must be filed in the Uniform Commercial Code records.

          (c)  The security interest granted herein shall attach as soon as the
     Company obtains any interest in any of the Collateral and before the
     Collateral becomes fixtures or before the Collateral is installed or
     affixed to any other collateral for the benefit of Issuer, to secure the
     indebtedness evidenced by the Company's Notes and all other indebtedness
     and obligations secured by this Loan Agreement, and all other sums and
     charges which may become due hereunder or thereunder. The security interest
     granted to the Issuer shall cover cash and non-cash proceeds of the
     Collateral, but nothing contained herein shall be construed as authorizing,
     either expressly or by implication, the sale or other disposition of the
     Collateral by the Company except on the terms and conditions set forth in
     this Loan Agreement.

          (d)  In the event of a default hereunder, the Issuer (or the Trustee
     as the assignee of the Issuer), pursuant to said Uniform Commercial Code
     shall have the option of proceeding as to both real and personal property
     in accordance with its rights and remedies in respect of the real property,
     in which event the default and remedy provisions of the Uniform Commercial
     Code shall not apply. The parties agree that, in the event an election is
     made to proceed with respect to the Collateral separately from the real
     property, the requirement of the Uniform Commercial Code as to reasonable
     notice of any proposed sale or disposition of the Collateral shall be met
     if such notice is 



                                      -31-



     mailed to the Company at the address for notice set forth
     herein at least five (5) days prior to the time of such sale or
     disposition.

          (e)  All replacements, substitutions and additions, and accessions to
     the Collateral shall become and be immediately subject to the security
     interest of this Loan Agreement and shall be covered thereby.  Company
     warrants and represents that all Collateral now is, and that all
     replacements thereof, substitutions therefor or additions and accessions
     thereto will be, free and clear of liens, encumbrances or security
     interests of others, except for Permitted Encumbrances.

          (f)  Company warrants that (i) its name, identity, and principal place
     of business are as referred to in Article X hereof; (ii) it has been using
     or operating under said name and identity without change for a continuous
     period of more than four (4) months prior to the date hereof; and (iii) the
     location of all tangible Collateral will be the real estate constituting
     the Project Sites to be acquired with the proceeds the Series 1996 Bonds.
     Company covenants and agrees that it will furnish the Issuer and Trustee
     with notice of any change in the matters addressed by clauses (i) or (iii)
     of this Section 3.28(f) at least thirty (30) days prior to the effective
     date of any such change, and Company will promptly execute any financing
     statement(s) or other instrument(s) deemed necessary by the Issuer or
     Trustee to prevent any filed financing statement from becoming misleading
     or losing its perfected status.

          (g)  Some of the items comprising the Collateral are goods that are or
     are to become, fixtures related to the real estate described on Exhibit A
     attached hereto and it is intended that, as to those goods, this Loan
     Agreement shall be effective as a financing statement filed as a fixture
     filing from the date of its filing for record in the real estate records of
     the county in which the real estate is located. The information in this
     Section 3.28(g) is provided in order that this Loan Agreement shall comply
     with the requirements of the Uniform Commercial Code as enacted in the
     State of Indiana, for mortgage instruments to be filed as financing
     statements. The Company is the "Debtor" and its name is as set forth in the
     definition thereof contained herein. The "Secured Party" is the Issuer with
     the Trustee being its assignee, and their respective names are as set forth
     in the definitions thereof contained herein.  The mailing address of the

     address of the Trustee and Issuer from which information concerning the
     security interest granted herein may be obtained is set forth in Article X

     comprising the Collateral is set forth hereinabove.

     Section 3.29.  BALANCE IN THE DEBT SERVICE RESERVE FUND.  Except when the
Company's obligations under this Loan Agreement have been released pursuant to
Section 10.8 hereof, at any time that the Debt Service Reserve Fund is less than

Trustee pursuant to Section 4.5 or 4.6 of the Indenture, the Company immediately
shall deposit moneys with the Trustee for deposit in the Debt Service Reserve
Fund as required under the Indenture so that it is Fully Funded.



                                      -32-



     Section 3.30.  REIMBURSEMENT OF ISSUER.  Upon demand, the Company shall
deposit money with the Trustee to reimburse the Issuer for (a) any deposits made
to the Debt Service Reserve Fund by the Issuer or the State, from whatever

released pursuant to Section 10.8 hereof; and (b)all costs and expenses
(including attorneys' fees and expenses and court costs) incurred by the Issuer

     Section 4.1.  DAMAGE.  The Company agrees to notify the Trustee immediately
(a) of any damage to the Mortgaged Property resulting from fire or other
casualty if such damage causes the Company to be unable to perform its
obligations under the IDEM Contract for a period in excess of thirty (30) days,
or (b) upon obtaining knowledge of the institution of any proceedings for the
condemnation or taking of the Mortgaged Property or any portion thereof for
public or quasi-public use if such condemnation causes the Company to be unable

Purchaser, either be used to repair, reconstruct, restore or replace such
Mortgaged Property or be deposited in the Redemption Account of the Bond Fund
for the redemption of Bonds in order to effect the prepayment of a portion of
the Note pursuant to Section 5.2 hereof.

     If the Company is not obligated to repair, reconstruct, restore or replace
such Mortgaged Property in order to perform its obligations under the IDEM

transferred promptly to the Trustee, and the Trustee shall deposit all Net
Proceeds into the Redemption Account of the Bond Fund for redemption of the
Bonds in order to effect the prepayment of a portion of the Note pursuant to

     So long as an event of default does not exist hereunder and the Project is
to be repaired, reconstructed, restored or replaced, any Net Proceeds received
by the Trustee pursuant to Section 3.13 or Section 4.2 hereof shall be released
from time to time by the Trustee to the Company upon the receipt of the written
request of an authorized officer of the Company specifying the expenditures made
or the indebtedness incurred in connection with such repair, reconstruction,
restoration or replacement and stating that such Net Proceeds, together with any
other moneys legally available for such purposes, will be sufficient to complete
such repair, reconstruction, restoration or replacement.  In such event, the
Company shall complete the repair, reconstruction, restoration or replacement of
such Mortgaged Property, whether or not 




                                      -36-



the Net Proceeds of insurance or
condemnation award received for such purposes are sufficient to pay for the

Trustee, within ninety (90) days after the completion of the repair,
reconstruction, restoration, or replacement of the Project, a restoration
certificate of its authorized Company representative stating that (i) the
Project has been repaired, reconstructed, restored, or replaced, and (ii) he or
she has made such investigation of such sources of information as are deemed to
be necessary, including pertinent records of the Company, and is of the opinion
that the repair, reconstruction, restoration, or replacement of the Project has
been fully paid for and that no claim or claims exist against the Issuer or the
Company or against the properties of either out of which a lien based on
furnishing labor or material for such repair, reconstruction, restoration, or
replacement of the Project, exists or might ripen; provided, however, there may
be excepted from the foregoing statement any claim or claims or liens
constituting Permitted Encumbrances. In the event such restoration certificate
shall state that there is a claim or claims in controversy which create or might
ripen into a lien, there shall be filed with the Issuer and the Trustee a
certificate of the Company when and as such claim or claims shall have been
fully paid or otherwise satisfied or released.

     Section 4.2.  OTHER PROVISIONS WITH RESPECT TO NET PROCEEDS.  The Company

Construction Fund and shall be invested or reinvested in Qualified Investments
subject to the Company's right to receive the same pursuant to Section 4.1
hereof.

     Section 4.3.  INSUFFICIENCY OF NET PROCEEDS.  If the Company is obligated
to use such Net Proceeds for any repair, reconstruction, restoration, or
replacement of the Project pursuant to Section 4. 1 hereof, and such Net
Proceeds are insufficient to pay in full the cost of any repair, reconstruction,
restoration, or replacement referred to in Section 4. 1 hereof, Company will
nonetheless complete the work and will pay any cost in excess of the amount of
the Net Proceeds held by the Trustee.

     Section 4.4.  EXCESS NET PROCEEDS.  After completion of the repair,
reconstruction, restoration, or replacement of the Project and delivery by the
Company of the restoration certificate pursuant to Section 4. 1 hereof, the
Trustee shall transfer all moneys then in the special trust account of the
Construction Fund to the Redemption Account for the redemption of Series 1996
Bonds in order to effect a prepayment of the Series 1996 Note pursuant to
Section 5.2 hereof.

for any foreclosure hereunder, or for the enforcement of any other appropriate
legal or equitable remedy, as the Trustee shall deem most effectual to protect
and enforce any of its rights or duties hereunder; provided, however that all
costs incurred by the Trustee and the Issuer under this Article shall be paid to
the Issuer and the Trustee by the Company on demand.

     Section 7.2.  FORECLOSURE AND SALE OF MORTGAGED PROPERTY.  During
occurrence and continuance of an event of default the Trustee may, with or
without entry, personally or by attorney, sell, to the extent permitted by law,

times, which such sale shall be made at public auction at such place in the
county in which the Mortgaged Property to be sold is situated and at such time
and upon such terms as may be fixed by the Trustee and briefly specified in the
notice of such sale or sales. Any sale by the Trustee may nevertheless, at its
option, be made at such other place or places, and in such other manner, as may

due, immediately thereupon shall become due and payable, anything in the 
Notes or this Mortgage to the contrary notwithstanding. The parties expressly 
agree that notice sent to the Company five (5) days before any such sale

whatsoever, whether at law or in equity, of the Company, in and to the premises,

     Section 7.4.  RECEIPT SUFFICIENT DISCHARGE FOR PURCHASER.  The receipt of
the Trustee or of the court officer conducting any such sale for the purchase
money paid at any such sale shall be a sufficient discharge therefor to any
purchaser of the property, or any part thereof, sold as aforesaid; and no such
purchaser or his representatives, grantees or assigns, after paying such
purchase money and receiving such a receipt, shall be bound to see to the
application of such purchase money upon or for the purpose of this Loan
Agreement, or shall be answerable in any manner whatsoever for any loss,
misapplication or non-application of any such purchase money or any part
thereof, nor shall any such purchaser be bound to inquire as to the necessity or
expediency of any such sale.

     Section 7.5.  SALE TO ACCELERATE NOTES.  In the event of any sale pursuant
to Section 7.2 hereof, the principal of the Notes and all other obligations of

provisions of this Article or otherwise, shall be paid to the Trustee, who shall
apply such funds as follows:

             FIRST:  To the payment of the costs and expenses of such sale, 
     including reasonable compensation to the Issuer, the Trustee, its or 
     their agents, attorneys and counsel, and the expenses of any judicial 
     proceedings wherein the same may be made, and of all expenses, 
     liabilities and advances made or incurred by the Issuer or the Trustee 
     as permitted by this Loan Agreement, together with interest on all 
     advances made by the Trustee, and to the payment of all taxes, 
     assessments or liens prior to the lien of this Loan Agreement, except 
     any taxes, assessments, liens, or other charges, subject to which the 
     property shall have been sold.

             SECOND:  To the payment of the whole amount then due, owing and 
     unpaid upon the Notes for principal, interest and premium, if any; and 
     in case such proceeds shall be insufficient to pay in full the whole 
     amount so due, owing or unpaid upon the

                                      - 44 -



     Notes, then ratably according to the aggregate of such principal and the 
     accrued and unpaid interest and premium, if any, without preference or 
     priority as between principal, interest or premium; such application to 
     be made upon presentation of the Notes and the notation thereon of the 
     payment, if partially paid, or the surrender and cancellation thereof, 
     if fully paid.

             THIRD:  To payment and satisfaction of the obligations of the 
     Company under Section 3.30.

             FOURTH:  To the payment of any other sums required to be paid by 
     the Company pursuant to any provisions of this Loan Agreement or of the 
     Notes.

             FIFTH:  To the payment of the surplus, if any, to the Company or 
     its successors or assigns, upon the written request of the Company or to 
     whomsoever may be lawfully entitled to receive the same upon its written 
     request, or as any court of competent jurisdiction may direct.

     Section 7.7.  PAYMENT OF DEFAULTED AMOUNTS ON DEMAND OF TRUSTEE.  In case
the Company shall:

          (i)    fail to pay any installment of interest on the Notes when and 
     as the same shall become due and payable, as therein and herein expressed;
     or

          (ii)   fail to pay the principal of the Notes, when and as the same
     shall become due and payable, whether at maturity or upon designation for
     prepayment or by declaration, or upon a sale as in Section 7.5 hereof
     provided, or otherwise; or

          (iii)  fail to pay amounts owed to the Issuer under Section 3.30;

then upon written demand of the Trustee the Company will pay to the Trustee the
whole amount which then shall have become due and payable on the Notes for
interest or principal or both, as the case may be, the whole amount then due
under Section 3.30, including interest as provided therein, and in addition
thereto such further amount as shall be sufficient to cover the cost and
expenses of collection, including a reasonable compensation to the Trustee, its
agents, attorneys and counsel, and any expenses or liabilities incurred by the
Trustee hereunder. The exercise by the Trustee under this Section 7.7 shall not
prevent acceleration of the Notes under Section 7.1.

     Section 7.8.  TRUSTEE MAY ENFORCE DEMAND.  In case the Company shall have
failed to pay such principal and interest and other amounts upon demand, the
Trustee, in its own name, may constitute such actions or proceedings at law or
in equity for the collection of the amounts so due and unpaid, and may prosecute
any such action or proceedings to judgment or final decree, and may enforce any
such judgment or final decree against the Company and collect the

                                      - 45 -



moneys adjudged or decreed to be payable out of the property of the Company 
wherever situated, in the manner provided by law.

     The Trustee shall, if permitted by law, be entitled to recover judgment as
aforesaid either before or after or during the pendency of any proceedings for
the enforcement of the lien of this Mortgage; and the right of the Trustee, to
recover such judgment shall not be affected by any entry or sale hereunder or by
the exercise of any other right, power or remedy for the enforcement of the
provisions of this Mortgage or the foreclosure of the lien hereof; and in case
of a sale of the Mortgaged Property and of the application of the proceeds of
sale, as in Section 7.6 provided, to the payment of the debt hereby secured, the
Trustee shall be entitled to enforce payment and to receive all amounts then
remaining due and unpaid upon the Notes then outstanding, and shall be entitled
to recover judgment for any portion of the debt remaining unpaid, with interest.

     No recovery of any judgment by the Trustee, and no levy of an execution
under any judgment upon the Mortgaged Property or upon any other property, shall
affect the lien of this Mortgage upon the Mortgaged Property or any part
thereof, or any lien, rights, powers or remedies of the Trustee hereunder, but
such lien, rights, powers or remedies of the Trustee shall continue unimpaired
as before.

     Any moneys thus collected by the Trustee under this Section shall be
applied by the Trustee as provided in Section 7.6 hereof.

     Section 7.9.  TRUSTEE ENTITLED TO APPOINTMENT OF RECEIVER.  The Company
further covenants that upon the happening of any event of default and thereafter
during the continuance of such event of default unless the same shall have been
waived as hereinbefore provided, the Trustee shall be entitled as a matter of
right if it shall so elect, (i) forthwith and without declaring the principal of
the Notes to be due and payable, or (ii) after declaring the same to be due and
payable, or (iii) upon the filing of an action to foreclose this Mortgage or to
enforce the specific performance hereof or in aid thereof or upon the
commencement of any other judicial proceeding to enforce any right of the
Trustee to the appointment of a receiver or receivers of the Mortgaged Property
and of all the earnings, revenues, rents, issues, profits and income thereof,
with such powers as the court making such appointment shall confer, which may
comprise any or all of the powers which the Trustee is authorized to exercise by
the provisions of Section 7. 1(c)(iii). The Company, if requested so to do by
the Trustee will consent to the appointment of any such receiver as aforesaid.

     Section 7.10.  REMEDIES CUMULATIVE.  Except as provided in Section 7.6
hereof, no remedy herein conferred upon or reserved to the Trustee is intended
to be exclusive of any other remedy or remedies, and each and every such remedy
shall be cumulative, and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute.

                                      - 46 -



     Section 7.11.  DELAY OR OMISSION NOT A WAIVER.  No delay or omission of the
Trustee to exercise any right or power accruing upon any event of default shall
impair any such right or power, or shall be construed to be a waiver of any such
event of default or an acquiescence therein; and every power and remedy given by
this Loan Agreement to the Trustee may be exercised from time to time and as
often as may be deemed expedient by the Trustee.

          Section 7.12.  WAIVER OF EXTENSION, APPRAISEMENT OR STAY LAWS.  To the
extent permitted by law, the Company will not during the continuance of any
event of default hereunder insist upon, or plead, or in any manner whatever
claim or take any benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
and terms of performance of this Loan Agreement; nor claim, take or insist upon
any benefit or advantage of any law now or thereafter in force providing for the
valuation or appraisement of the Mortgaged Property, or any part thereof, prior
to any sale or sales thereof which may be made pursuant to any provisions herein
contained, or pursuant to the decree, judgment or order of any court of
competent jurisdiction; nor after any such sale or sales, claim or exercise any
right under any statute heretofore or hereafter enacted by the United States of
America or by any state or territory, or otherwise, to redeem the property so
sold or any part thereof; and the Company hereby expressly waives all benefits
or advantage of any such law or laws and covenants not to hinder, delay or
impede the execution of any power herein granted or delegated to the Trustee,

     (b)  The obligation of the Issuer to consummate the transaction

as provided in subparagraph (d) below shall be subject to full performance by
the Company of the provisions of (c) below and satisfaction of all of the
following conditions:

           (i)   at the time the IDEM Termination Event occurs, at the time 
      option is exercised, and at the time of Closing (as deemed below): 
      (A) there shall be securities outstanding under the Public Debt 
      Instruments, and the outstanding principal balance of the Note shall 
      be in excess of $7,500,000; (B) no event of default under Section 7. 
      1(i) shall have occurred and be continuing;

           (ii)  at the time of Closing (as deemed below): (A) the Company 
      shall have fully performed all of its obligations under Sections 3.11, 
      3.13, 3.15, 3.17, 3.21 and 3.33(e), to the extent performance of such 
      obligations has become due prior to Closing, and (B) any failure by 
      the Company to perform its obligations under Sections 3.7, 3.8, 3.9, 
      3.23 or 3.33(a), (b), and (c), shall have been remedied in the manner 
      and at the times provided in subsection (b)(iv) below;

           (iii) at the time the IDEM Termination Event occurs, the 
      Company shall not have been notified by IDEM in writing that IDEM is 
      terminating the IDEM Contract as a result of a breach by the Company 
      of its obligations under the IDEM Contract; and,

           (iv) not later than sixty (60) days after the Company exercises 
      the option granted herein, the Company shall have provided to the 
      Issuer such evidence as the Issuer reasonably may require that the 
      Company has fully performed its obligations under Sections 3.7, 3.8, 
      3.9, 3.23 and 3.33 (a), (b) and (c). Any default under such Sections 
      shall be remedied by the Company prior to the time of Closing. In the 
      event the default cannot be remedied by the payment of cash by the 
      Company, the Company shall be permitted to remedy such default by 
      either transferring the portion of the Mortgaged Property with the 
      unremedied default to the Issuer together with an amount equal to the 
      diminution in fair market value of such portion of the Mortgaged 
      Property caused by such default or, at the option of the Issuer, such 
      Mortgaged Property shall be retained by the Company (free of all liens 
      created under this Loan Agreement) and the Company shall pay to the 
      Issuer the fair market value of such property (determined as if such 
      default had not occurred).  At the Closing, the Issuer shall reimburse 
      the Company for reasonable expenses incurred by the Company in 
      providing evidence of its performance of its obligations under the 
      Sections cited above in this subsection (b)(iv), provided that (l) all 
      costs of such remedies shall be borne by the Company and (2) if the 
      Closing does not occur as a result of the Company's failure to satisfy 
      the conditions set forth in this subsection (b) or failure to perform 
      as contemplated by subsection (c), all such expenses shall be borne by 
      the Company. Notwithstanding the foregoing, if such conditions are not 
      satisfied within such 60 day period, the Company may continue to 
      attempt to satisfy such conditions for an additional 120 days so long 
      as the Company (1) pays any past due payments on the Note, and 
      (2) continues to make current payments on the Note as they

                                      - 52 -



      come due, and (3) otherwise complies with the Sections of this Loan 
      Agreement listed above in this subsection (b)(iv), and (4) continues 
      to maintain and insure the Mortgaged Property pursuant to Sections 
      3.11 and 3.13 hereof. The fair market value of the applicable portion 
      of the Mortgaged Property, or the amount of any diminution in such 
      fair market value, thereof, as the case may be, shall be determined, 
      as of the date of the appraisal, by an MAI appraiser with experience 
      in valuing such types of property reasonably satisfactory to the 
      Company and the Issuer. All appraisal costs shall be borne by the 
      Company.

     (c)  Within fifteen (15) days after the date the conditions set forth in
subsection (b) above have been satisfied, at a closing (the "Closing") to be
held on a date and at a time that is convenient to each of the parties, at the
offices of the Issuer in Indianapolis, Indiana, the Company shall execute,
acknowledge and deliver to the Issuer each of the following, all in form and
substance acceptable to the Issuer, the Trustee and the Original Purchaser (if
still a bondholder):

           (i)   general warranty deeds (together with appropriate vendors 
      affidavits) by which the Company shall convey to the Issuer marketable 
      fee simple title (or assignment of leasehold interest) to the Project 
      Sites, subject only to Permitted Encumbrances (provided that those 
      described in clauses (vi) and (vii) of the definition thereof shall be 
      either discharged or to the extent not dischargeable such encumbrances 
      shall be insured over pursuant to an owner's policy of title insurance 
      from an insurance company reasonably satisfactory to the Issuer with 
      the costs of such policy to be borne by the Company); and

           (ii)  bills of sale and assignments by which the Company shall 
      transfer, assign and convey to the Issuer good and merchantable title 
      (or assignment of leasehold interest) to the Company's interest in all 
      other of the Mortgaged Property, subject only to Permitted 
      Encumbrances (provided that those described in clauses (vi) and (vii) 
      of the definition thereof shall be either discharged or insured in the 
      manner set forth in (c)(i) above); and

           (iii) a transferable, royalty-free, non-exclusive license for 
      the use of all Equipment-related software in connection with the 
      performance of the remaining term of the IDEM Contract; and

           (iv) such evidence as the Issuer may require that the actions 
      contemplated by this Section 10.8 have been duly authorized by all 
      necessary corporate action on the part of the Company; and

           (iv) an opinion (in the form of the ABA Third Party Opinion 
      Accord) of counsel to the Company to the effect that all documents 
      executed by the Company and delivered to the Trustee at the Closing 
      have been duly authorized, executed and delivered and are enforceable 
      against the Company in accordance with their respective terms, and

                                      - 53 -



      that the execution, delivery and performance thereof does not conflict 
      with or constitute a breach of or default under the Company's 
      organizational documents, or any agreement, instrument, document, 
      order, judgment or decree to which it is a party or by which it or its 
      properties are bound; and

           (vi)  an indemnification agreement, by which the Company shall 
      agree to indemnify, defend and hold harmless the Issuer, the Trustee 
      and the Original Purchaser and their respective members, directors, 
      officers, agents, attorneys, employees, successors and assigns from 
      and against any loss, cost, damage, liability, expense (including 
      attorney's fees), claim, demand or cause of action (including any and 
      all environmental claims, personal injury and property damage claims) 
      that (l) arises out of or relates to the operation of the Project or 
      the operation or ownership of the Mortgaged Property at any time prior 
      to the Closing, or (2) is incurred as a result of any 
      misrepresentation or inaccuracy in any document, instrument, 
      agreement, affidavit, report or certificate executed and/or delivered 
      by the Company in connection with the transaction contemplated by this 
      Section 10.8; provided, however, that the foregoing shall not be 
      deemed to require the Company to indemnify, defend and hold harmless 
      the Issuer, the Trustee and the Original Purchaser, and their 
      respective members, directors, officers, agents, attorneys, employees, 
      successors and assigns from and against any loss, cost, damage, 
      liability, expense (including attorney's fees), claim, demand, or 
      cause of action that arises as a consequence of the IDEM Termination 
      Event itself (other than those items indemnified above) or the 
      nonpayment of the Bonds.

     (d)  Upon full performance by the Company of the provisions of (c) above,
the Note, duly cancelled, shall be delivered to the Company and all liability of
the Company to the State, the Issuer, the Trustee and the Original Purchaser
(excluding its liabilities under Section 3.15 and 3.33(e) to the extent such
liability relates to events that occurred prior to the Closing, and under the
indemnification agreement identified in subparagraph (c)(vi) above) hereunder,
under the Indenture, and under the Bond Placement Agreement shall cease and
determine.  If the Trustee is then holding reserves established by the Company
pursuant to clauses (vi) or (vii) of the definition of Permitted Encumbrances,
such reserves together with the Company's portion of the Debt Service Reserve
Fund shall be released to the Company.

     (e)  Any moneys owed to the Company for services rendered under the IDEM
Contract prior to Closing or any claims for compensation or equitable
adjustments the Company has against the State pursuant to the IDEM Contract, at
the time of Closing, shall remain the property of the Company (free and clear of
the lien of this Mortgage) notwithstanding any transfer of the IDEM Contract to
the Issuer or the Trustee pursuant to the provisions hereof and the Indenture.

     Section 10.9.  ISSUER PROCEDURES.  The Issuer agrees that whenever a
consent, waiver or an approval contemplated by the terms hereof is required, the
Issuer may take such action through its Executive Director and other officers,
in consultation with Issuer's counsel if deemed necessary and appropriate by the
Executive Director and such officers.  Notwithstanding the

                                      - 54 -



above provision, the Executive Director and such officers shall not be 
precluded from seeking official action by the full membership of the Issuer 
with regard to any such consent, waiver or approval.

                               (End of Article x)
