Ladies and Gentlemen:

      Dravo Black River Limited Partnership, a Delaware limited partnership
(the "SPV"), hereby agrees with you as follows:

SECTION 1   PURCHASE AND SALE OF CONSTRUCTION NOTES.

      Section 1.1 Issuance of Construction Notes.  

            (a)   Authorization of Construction Notes.  The SPV has
      authorized the issuance of an aggregate principal amount of up to
      Fifty Million Dollars ($50,000,000) (the "Commitment Amount") of its
      Senior Secured Construction Notes due September 30, 1995 (the
      "Construction Notes").  The Construction Notes shall be to the effect
      and substantially in the form of Exhibit A hereto.

            (b)   Purchase and Sale of Construction Notes.  The SPV hereby
      agrees to sell to you, and you hereby agree to purchase from the SPV,
      subject to the terms and conditions of this Agreement, Construction
      Notes in an aggregate amount equal to the Commitment Amount. 

            (c)   Initial Funding of Construction Notes. The closing of the
      initial sale of Construction Notes (the "Initial Funding") shall be held
      on August 18, 1994, or such other date as may be agreed to in writing
      by you and the SPV (the "Initial Funding Date"), at 10 a.m., Hartford,
      Connecticut time, at the offices of Hebb & Gitlin, your special
      counsel, One State Street, Hartford, Connecticut.  At the Initial
      Funding, a single Construction Note will be delivered to you, which
      Construction Note will be (i) dated the Initial Funding Date, 
<PAGE>                                -1-
<PAGE>
(ii) payable as indicated on Annex 1 hereto, and (iii) in a stated principal
amount equal to Fifty Million Dollars ($50,000,000).  Delivery of such
Construction Note to you shall be made on the Initial Funding Date against
payment by you of the principal amount set forth in an Approved Draw
Request delivered pursuant to Section 1.3 hereof.

      Section 1.2 Advance of Additional Funds.  Subject to the terms and
conditions of this Agreement, on each Funding Date (including, without
limitation, the Initial Funding Date) you agree to advance (each an
"Advance") from time to time, but not more often than once in any period of
thirty (30) consecutive days and in an amount not less than Five Hundred
Thousand Dollars ($500,000) (except in the case of Advances made pursuant
to clause (ii) below), funds for the benefit of the SPV in an aggregate
principal amount equal to the sum of (i) the amount set forth in a Draw
Request delivered in compliance with Section 1.3 in respect of such Funding
Date and (ii) such amount as may then be required to pay accrued interest
on the outstanding Construction Notes, the fees provided for in Section 1.7
and (in connection with the Advance to be made on the Conversion Date) the
Required Reserve Payment, whether or not such amounts shall be specified
in a Draw Request (the SPV hereby authorizing you to advance the funds
pursuant to this clause (ii) without further direction or documentation of
any kind), provided that the maximum aggregate principal amount of all
Advances hereunder, including the Advance made on the Initial Funding
Date, shall not exceed the Commitment Amount, provided, further, that, with
respect to any Subsequent Funding Date, the amount of any Advance shall
be computed after giving effect to the Equity Amount to be paid pursuant to
Section 3.15(b) of the Lime Security Agreement on or prior to such
Subsequent Funding Date, and the application of such Equity Amount to the
payment of Construction Costs and funding of the Debt Service Reserve to
the extent contemplated by Section 8.19.  Advances (other than those made
pursuant to clause (ii) of the immediately preceding sentence) shall be
deposited into the Construction Account, the Construction Completion
Account and the Debt Service Reserve in accordance with this Agreement
and the other Transaction Documents.  Your obligations to make Advances
shall terminate automatically upon the earliest to occur of (x) any
acceleration of the Construction Notes pursuant to Section 13.2 hereof, (y)
the Construction Note Maturity Date, or (z) the consummation of the
transactions to be effected on the Conversion Date.  You shall record your
Advances on your Construction Notes, but any failure to make any such
notation or any error in any such notation shall not affect the obligations
of the SPV under such Construction Note or any other Transaction
Document.  At any time, the aggregate principal amount of the Construction
Notes outstanding shall be the sum of the Advances made hereunder and not
paid. 

      Section 1.3 Draw Requests.  The Construction Manager shall deliver a
Draw Request signed by the SPV to you, the Independent Engineer, the
Collateral Agent and the Disbursement Agent at least five (5) Business
Days prior to any requested Funding Date.  The Draw Request shall comply
with Sections 5.7 and 5.29 or Sections 6.3 and 6.4, as the case may be, and
shall be substantially in the form of Exhibit B hereto and in substance
satisfactory to you, and shall specify (i) the requested Funding Date and
(ii) the total amount of the requested Advance.  Each Draw Request shall
contain a representation and warranty by the Construction Manager and the
SPV that all of the applicable conditions precedent to the Advance
requested have been satisfied.  You shall not be obligated to make an
Advance with respect to any amount requested in a Draw Request which
amount (1) has not been approved by the Independent Engineer or (2) when
added to the aggregate principal amount of all prior Advances is in excess
of the Commitment Amount.

      Section 1.4 Conversion Date Advances.  On the Conversion Date, Lime will
deliver to you a Draw Request in compliance with Section 1.3, which Draw
Request shall include all remaining unpaid Construction Costs (including,
amounts to be deposited into the Construction Completion Account in
respect of Punch List Items), the Required Reserve Payment and an amount
equal to the result of (a) the sum of (i) the Commitment Amount, plus (ii)
Twelve Million, Four Hundred Thousand Dollars ($12,400,000) plus (iii) Five
Million, Three Hundred Thousand Dollars ($5,300,000) minus (b) the sum of (i)
all Construction Costs plus Six Months' Debt Service.  Any Required Reserve
Payment shall be paid to the Disbursement Agent for deposit into the Debt
Service Reserve in accordance with the Deposit and Disbursement
Agreement.

      Section 1.5 Interest Rate and Maturity of Construction Notes.  

            (a)   Interest Rate.  The Construction Notes will bear interest
      on the unpaid principal balance thereof at the rate of 10.13% per
      annum payable monthly. Overdue principal and (to the extent permitted
      by Applicable Law) any overdue installment of interest on the
      Construction Notes shall bear interest at a rate equal to the lesser
      of (x) the highest rate allowed by law or (y) 12.13% per annum.  Interest
      on the Construction Notes shall be calculated on the basis of a 360-
      day year and actual days elapsed.

            (b)   Maturity.  The Construction Notes will mature on September
      30, 1995 (the "Construction Note Maturity Date").

      Section 1.6 Payments on the Construction Notes.  

            (a)   Interest Payments.  Interest on the Construction Notes
      shall be payable monthly on each Debt Payment Date commencing on the
      Debt Payment Date next succeeding the Initial Funding Date until the
      principal amount thereof shall become due and payable.

            (b)   Principal Payments.  All or a portion of the outstanding
      principal amount of the Construction Notes shall be subject to
      prepayment only under the circumstances and upon the terms, set
      forth in Section 1.6(c) or Section 11 of this Agreement; otherwise the
      Construction Notes shall not be prepayable in whole or in part.  The
      principal amount of the Construction Notes outstanding on the
      Construction Note Maturity Date shall be payable on such date with
      the proceeds of the Term Notes.

            (c)   Prepayment.  If the Construction Notes are outstanding on
      the Construction Option Amount Prepayment Date, the SPV may prepay
      the Construction Option Amount of the Construction Notes, or any
      portion thereof, on the Construction Option Amount Prepayment Date,
      together with interest on the Construction Option Amount, or such
      portion, accrued to the Construction Option Amount Prepayment Date. 
      The SPV shall give written notice of any such prepayment to the
      Collateral Agent and to the Holders not less than ten (10) days nor
      more than thirty (30) days before the Construction Option Amount
      Prepayment Date, stating that the Construction Option Amount, or a
      specified portion thereof, will be prepaid on such date.  Notice of
      such prepayment having been so given, the Construction Option
      Amount, or such specified portion thereof, accrued interest thereon
      (but not any Make-Whole Amount in respect thereof) and the
      Construction Exit Fee shall become due and payable on the
      Construction 
<PAGE>                                -3-<PAGE>
Option Amount Prepayment Date.  As used in this Section 1.6(c), the following
terms have the following meanings:

                  "Construction Exit Fee" shall mean, if the principal amount
            of Construction Notes to be prepaid on the Construction Option
            Amount Prepayment Date is $50,000,000, a fee equal to Seven
            Hundred Fifty Thousand Dollars ($750,000) and, if the principal
            amount of Construction Notes so to be prepaid is a lesser
            amount, a portion of such fee equal to (i) $750,000 multiplied by
            (ii) the quotient of (a) the principal amount so to be prepaid
            divided by (b) $50,000,000.

                  "Construction Option Amount" means a principal amount of
            the Construction Notes equal to Fifty Million Dollars
            ($50,000,000).

                  "Construction Option Amount Prepayment Date" means the
            date in the ninth calendar month after the month in which the
            Initial Funding Date falls that is the same numerical date of
            the month as the date of the Initial Funding Date.

      Section 1.7 Fees Payable to the Purchaser in Connection with
Construction Notes.

            (a)   Commitment Fees.  Lime, on behalf of the SPV, has
      heretofore paid you $500,000 in respect of your consideration of the
      financing contemplated by this Agreement.  On or prior to the Initial
      Funding Date, the SPV shall pay or cause to be paid to you an
      additional Seven Hundred Forty-Eight Thousand Dollars ($748,000) in
      consideration of your commitment hereunder.

            (b)   Rate Delayed Delivery Fee.  If all of the Construction Notes
      have not been advanced before the first day of the Rate Commitment
      Period with respect thereto, then, beginning on the last day of the
      first month following the commencement of such Rate Commitment
      Period and continuing on the last day of each month thereafter
      during such Rate Commitment Period, the SPV shall pay to you in
      respect of the amount of such unadvanced Construction Notes a fee
      (the "Rate Delayed Delivery Fee") equal to (i) the average daily
      balance of the unadvanced principal amount of the Construction Notes
      during such month, multiplied by (ii) a rate per annum equal to the
      Uncompensated Yield Rate with respect to the Construction Notes
      (determined as of the Rate Acceptance Date with respect to the
      Construction Notes), computed on the basis of a 360-day year and
      actual days elapsed, multiplied by (iii) the quotient of (x) the number
      of days in such month divided by (y) 360.  As used herein, the "average
      daily balance" for any month shall mean the sum of the unadvanced
      balances on each and every day during such month divided by the
      number of such days.

            (c)   Cancellation Fee.  The SPV may at any time, upon thirty (30)
      days prior written notice to you, cancel all or any portion of the
      Unused Commitment, provided that, in the written opinion of the
      Independent Engineer (which shall be reasonably acceptable to you),
      the portion of the Unused Commitment remaining after such
      cancellation is sufficient to pay all Construction Costs as well as
      the initial funding of the Debt Service Reserve in an amount equal to
      One Year's Debt Service.  Upon any such cancellation and, in any
      event, if the entire amount of the Commitment Amount has not been
      borrowed or cancelled prior to the earlier to occur of (i) the
      Conversion Date or (ii) the Construction
<PAGE>                                -4-<PAGE>
      Note Maturity Date, the SPV shall immediately pay to you a
      cancellation fee (a "Cancellation Fee") as follows:

                  (A)   the amount of Construction Notes which has been so
            cancelled or not borrowed, multiplied by

                  (B)   (1) the Hedge Treasury Security Bid Price Increase
            with respect to the Construction Notes (determined as of the
            date of such notice, the Conversion Date or the Construction
            Note Maturity Date, as the case may be), divided by (2) the Hedge
            Treasury Security Bid Price.

      In no event shall any Cancellation Fee be less than zero ($0).  The
      Cancellation Fee shall compensate you for lost opportunity costs and
      the costs of re-establishing any investment portfolio position
      altered at the time the relevant interest rate was accepted by the
      SPV.  Such amount shall not be deemed to compensate you for any
      other fees incurred in connection with the preparation of, or the
      closing or funding of the transaction contemplated by, this
      Agreement.  Upon payment of the Cancellation Fee, the Rate Delayed
      Delivery Fee shall cease to accrue with respect to that portion of
      the Unused Commitment so cancelled.

            (d)   Servicing Fee.  The SPV shall pay to you a construction
      servicing fee (the "Construction Servicing Fee") of Fifty Thousand
      Dollars ($50,000) per annum during the Construction Period, payable in
      equal installments semi-annually in arrears on each Debt Payment
      Date, commencing on the Debt Payment Date next succeeding the Initial
      Funding Date, with a final payment on the Conversion Date, provided
      that the Construction Servicing Fee due on the first Debt Payment
      Date and the Conversion Date shall be in amounts equal to a ratable
      portion of the Construction Servicing Fee then due for the period
      ending on such date and commencing on, in the case of the first Debt
      Payment Date, the Initial Funding Date and in the case of the
      Conversion Date, the Debt Payment Date immediately prior thereto.  

            (e)   Manner of Payment of Fees; Interest on Overdue fees.  All
      fees required by this Section 1.7 shall be paid in the same manner as
      payments made in respect of the Construction Notes.  Any amount of
      fees not paid on the date due shall thereafter bear interest at a
      rate per annum equal to the highest rate from time to time applicable
      to any overdue payment in respect of any of the Construction Notes.

      Section 1.8  Use of Proceeds of Construction Notes.  The proceeds of
the Construction Notes will be used to pay Construction Costs, Transaction
Expenses, the Required Reserve Payment and the distribution (if any)
provided for in the last sentence of Section 2.1(b) of the Deposit and
Disbursement Agreement, and for no other purpose.  The SPV shall not use
the proceeds of the Construction Notes to pay any Contingency Costs
unless such Contingency Costs are determined in writing by the Independent
Engineer to be reasonably and necessarily incurred and you shall have
concurred in such determination; provided, however, that the SPV may pay
Contingency Costs that do not exceed $100,000 with respect to any
individual instance and $750,000 in the aggregate (and enter into any
change orders to effect the foregoing) without the prior consent of the
Independent Engineer.  On the Conversion Date, the amount of the Required
Reserve Payment shall be deposited by the SPV to the Debt Service Reserve.

SECTION 2   EXCHANGE OF CONSTRUCTION NOTES FOR TERM NOTES.

      Section 2.1 Issuance of Term Notes.

            (a)   Authorization of Term Notes.  The SPV has authorized the
      issuance of up to an aggregate principal amount of Fifty Million
      Dollars ($50,000,000) of its Senior Secured Term Notes due August 1,

      substantially in the form of Exhibit C hereto.

            (b)   Delivery and Acceptance of Term Notes; Payment of
      Construction Notes.  Subject to the terms and conditions of this
      Agreement, the SPV hereby agrees to execute and deliver to you, and
      you hereby agree to accept from the SPV, as payment in full of the
      outstanding principal amount of the Construction Notes, a principal
      amount of Term Notes equal to the aggregate principal amount of the
      Construction Notes outstanding on the Conversion Date after giving
      effect to all Advances required by Section 1 of this Agreement,
      including, without limitation, the Advances contemplated by Section
      1.4.

            (c)   Conversion Date Closing.  The closing of the SPV's issuance
      of the Term Notes (the "Term Note Closing") shall be held on the
      Conversion Date at 10 a.m., Hartford, Connecticut time, at the offices
      of Hebb & Gitlin, One State Street, Hartford, Connecticut.  At such
      closing, a single Term Note will be delivered to you, which Term Note
      will be (i) dated the Conversion Date, (ii) payable as indicated on
      Annex 1 hereto, and (iii) in a principal amount equal to the aggregate
      principal amount of the Construction Notes outstanding on the
      Conversion Date after giving effect to all Advances required by

      Advances contemplated by Section 1.4.

      Section 2.2 Payments on the Term Notes.

      payment required by Section 2.2(b) and paying the entire outstanding

      Maturity Date, the SPV shall pay, and there shall become due and
      payable on each Debt Payment Date commencing on the first Debt
      Payment Date next succeeding the Conversion Date, an installment of
      principal together with interest thereon in the amount set forth on
      Annex 2 hereto opposite such date.  The Term Notes will bear interest
      at the rate of 10.13% per annum calculated on the basis of a 360-day
      year of twelve 30-day months.  Without limitation of the foregoing, all
      of the principal of the Term Notes remaining outstanding on August 1,
      2010 (if any) together with interest accrued thereon, shall become due
      and payable on August 1, 2010.

            (b)   Prepayment Upon Total Loss.  Upon the occurrence of a Total
      Loss, the entire principal amount of the Term Notes shall become
      immediately due and payable, without Make-Whole Amount, and the SPV
      shall take the actions set forth in Section 11.3.

      Date, the SPV may prepay the entire principal amount of the Term
      Notes at any time together with

                  (i)   an amount equal to the Make-Whole Amount at such
            time in respect of the principal amount of the Term Notes being
            so prepaid,

                  (ii)  interest on such principal amount accrued to the
            prepayment date, and

                  (iii) all other amounts due and owing to you and the
            Collateral Agent hereunder or under any other Transaction
            Document.

            (b)   Prepayment Without Make-Whole Amount.  If the SPV has not
      exercised the prepayment rights with respect to the Construction
      Notes set forth in Section 1.6(c) before the Conversion Date (and as a
      result there are no Construction Notes outstanding on the
      Construction Option Amount Prepayment Date), the SPV may prepay the
      Term Option Amount of the Term Notes, or any portion thereof, on the
      Term Option Amount Prepayment Date, together with interest on the
      Term Option Amount, or such portion, accrued to the Term Option
      Amount Prepayment Date.  The SPV shall give notice of any such
      prepayment to the Collateral Agent and to the Holders not less than
      ten (10) days nor more than thirty (30) days before the Term Option
      Amount Prepayment Date, stating that the Term Option Amount, or a
      specified portion thereof, will be prepaid on such date.  Notice of
      such prepayment having been so given, the Term Option Amount, or
      such specified portion thereof, accrued interest thereon (but not any
      Make-Whole Amount in respect thereof) and the Term Exit Fee shall
      become due and payable on the Term Option Amount Prepayment Date. 
      As used in this Section 2.3(b), the following terms have the following
      meanings:

                  "Term Exit Fee" means, if the principal amount of Term
            Notes to be prepaid on the Term Option Amount Prepayment Date
            is the $50,000,000, a fee equal to Seven Hundred Fifty Thousand
            Dollars ($750,000) and, if the principal amount of Term Notes so
            to be prepaid is a lesser amount, a portion of such fee equal to
            (i) $750,000 multiplied by (ii) the quotient of (a) the principal
            amount so to be prepaid divided by (b) $50,000,000.

                  "Term Option Amount" means a principal amount of the Term
            Notes equal to Fifty Million Dollars ($50,000,000).

                  "Term Option Amount Prepayment Date" means May 1, 1995.

      Section 2.4 Notice of Optional Prepayment.  The SPV shall give written
notice of any optional prepayment of Term Notes pursuant to Section 2.3(a)
to the Collateral Agent and to the Holders of Term Notes not less than ten
(10) days nor more than thirty (30) days before the date fixed for
prepayment, specifying 

            (a)   such date, and
<PAGE>                                -7-<PAGE>
            (b)   that such prepayment is being made pursuant to Section
      2.3(a) of this Agreement.

Notice of prepayment having been so given, the aggregate outstanding
principal amount of the Term Notes together with the Make-Whole Amount (as
calculated by you absent manifest error), if any, and accrued interest
thereon shall become due and payable on the specified prepayment date.

      Section 2.5 Application of Prepayments.  Each prepayment made
pursuant to Section 1.6(c) or Section 2.3 shall reduce pro rata the amounts
of principal becoming due on each Debt Payment Date subsequent to the date
of such prepayment, such pro rata reduction to be determined by multiplying
the amount of each required payment of principal set forth on Annex 2
hereto by the quotient of the principal amount of Notes so prepaid divided
by the principal amount of Notes outstanding immediately prior to such
prepayment.  Immediately after any such prepayment, Annex 2 hereto shall
be deemed to have been amended to (i) reduce subsequent required payments
of principal as aforesaid, and (ii) reduce the amount of interest payable on
each subsequent Debt Payment Date to an amount equal to the amount of
accrued and unpaid interest on the outstanding principal amount of the
Notes to such date (assuming for such purpose that all payments will be
made on the date due).

      Section 2.6 Term Servicing Fee.  The SPV shall pay to you a term
servicing fee of Twenty-Five Thousand Dollars ($25,000) per annum, payable
in equal installments semi-annually in arrears on each Debt Payment Date,
commencing on the Debt Payment Date next succeeding the Conversion Date,
with a final payment on the Term Note Maturity Date, provided that the
amount of such fee due on the first Debt Payment Date after the
Conversion Date and the amount due on the Term Note Maturity Date shall be
in amounts equal to a ratable portion of such fee then due for the period
ending on such date and commencing on, in the case of such first Debt
Payment Date after the Conversion Date, the Conversion Date, and in the
case of the Term Note Maturity Date, the Debt Payment Date immediately
prior thereto.

      Section 2.7 Surrender of Term Notes on Prepayment.  If any Term Note is
prepaid, such Term Note shall be surrendered to the SPV for cancellation
and shall not be reissued, and no Term Note shall be issued in lieu of the
prepaid principal amount of any Term Note.

      Section 2.8 No Other Prepayments.  Except as provided in this Section 2,
the SPV may not make any prepayment (whether directly or indirectly, or by
purchase or other acquisition) in respect of the Term Notes.

SECTION 3   WARRANTIES AND REPRESENTATIONS OF PURCHASER.

      You represent and warrant to the SPV as follows:

      Section 3.1 Purchase for Investment.  That you are purchasing the
Notes for your own account for investment and with no present intention of
distributing or reselling the Notes or any part thereof, but without
prejudice to your right at all times to
<PAGE>                                -8-<PAGE>
            (a)   sell or otherwise dispose of all or any part of the Notes
      under a registration statement filed under the Securities Act, or in a
      transaction exempt from the registration requirements of such Act,
      and

            (b)   have control over the disposition of all of your assets to
      the fullest extent required by any Applicable Law.

It is understood that, in making the representations set forth in
Section 4.2 and Section 4.27 hereof, the SPV is relying, to the extent
applicable, upon your representation as aforesaid.

      Section 3.2 ERISA.    With respect to each source of funds to be used
by you to purchase the Construction Notes (the "Source"), the following
statement is accurate as of the Initial Funding Date:

                  The Source is assets none of which constitutes assets of
            an "employee benefit plan" (as defined in Section 3 of ERISA)
            maintained by the SPV,  Lime or any ERISA Affiliate or of a
            "plan" (as defined in Section 4975(e)(1) of the Code) maintained
            by the SPV or Lime or any ERISA Affiliate.  In making this
            representation, you are relying upon the list of employee
            benefit plans, plans and trusts maintained by the SPV, Lime and
            their ERISA Affiliates (as set forth on Part 4.21(f) on Annex 3
            attached hereto) which have contracts with you.

      As used herein, "plan" and "employee benefit plan" shall have the
      meaning set forth in Title I, section 3(3) of ERISA.

SECTION 4   WARRANTIES AND REPRESENTATIONS OF THE SPV.

      To induce you to enter into this Agreement and to purchase the
Construction Notes, the SPV warrants and represents as follows:

      Section 4.1 Organization and Existence.  The SPV is a limited
partnership duly organized, validly existing and in good standing under the
laws of the state of Delaware, and has all requisite power and authority to
enter into and perform its obligations under this Agreement, to own its
Property, and to conduct its business in the manner and in the places in
which it is presently proposed to be conducted.

      Section 4.2 Due Authorization; No Conflict.  Each of this Agreement
and the other Transaction Documents to which the SPV is a party has been
duly authorized by all necessary action on its part, has been duly executed
and delivered by the SPV, and its execution, delivery and performance
thereof do not (i) violate the Partnership Agreement, (ii) contravene any
Applicable Law binding on it or affecting the Project, (iii) contravene or
result in any breach of, or constitute a default under, any indenture,
mortgage, loan agreement, deed of trust, lease or other agreement or
instrument to which it is a party or by which it is bound or (iv) result in, or
require, the creation or imposition of any Lien (other than Permitted Liens)
upon or with respect to any of the Property now owned or hereafter
acquired by it.

      Section 4.3 Enforceability.  Each of this Agreement and the other
Transaction Documents to which the SPV is a party constitutes its legal,
valid and binding obligation, 
<PAGE>                                -9-<PAGE>
enforceable against it in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and other similar laws affecting the enforcement of creditors'
rights generally and by general equitable principles.

      Section 4.4 Litigation.  There is no action, suit, investigation,
proceeding or arbitration pending or to the SPV's knowledge threatened
against the SPV, any of its Properties, the Project, the Site or the Black
River Common Facilities; and no such proceeding is pending or threatened
against any of the foregoing that questions the validity, enforceability or
performance of this Agreement, the Notes or any of the other Transaction
Documents.  Except as set forth on Part 4.4 of Annex 3 attached hereto,
there is no action, suit, proceeding or arbitration pending or, to the best
knowledge of the SPV, threatened against the SPV or Lime that (if and when
decided) could reasonably be expected to have a material adverse effect on
their respective business conditions (financial or otherwise) or
operations, or the fulfillment of the Projections, or that could reasonably
be expected to materially and adversely affect the ability of either of
them to perform its obligations under any of the Transaction Documents, or
the maintenance of the Project, the Site, the Black River Common Facilities,
or the installation, construction, testing, ownership, leasing, use,
possession, operation and maintenance of the Project or any part thereof,
or the consummation of the transactions contemplated by this Agreement,
the Notes or any of the other Transaction Documents.

      Section 4.5 Governmental Approvals.  All Governmental Approvals
required in connection with the execution and delivery of this Agreement
and each other Transaction Document to which the SPV is a party, and all
material Governmental Approvals required in connection with the
construction of the Project or any part thereof as contemplated by the
Transaction Documents, have been obtained and are completely and
accurately listed in Annex 4 hereto, together with the name in which each
such Governmental Approval must be issued.  All such Governmental
Approvals have been given, obtained, made, filed or recorded, as the case
may be, and each is subsisting and in full force and effect and contains no
condition required to be met on the date hereof which has not been met, and
no such Governmental Approval is subject to any pending or, to the SPV's
knowledge, threatened, suit, action, inquiry, investigation, proceeding or
appeal (administrative, judicial or otherwise).  The time for appeal with
respect to each such Governmental Approval has expired (or if an appeal
has been taken the same shall have been dismissed or otherwise been
finally determined to be unsuccessful).  Such Governmental Approvals are
free from conditions or requirements which could reasonably be expected to
affect materially and adversely (i) the performance by the SPV and Lime
under the Transaction Documents, (ii) the construction of the Project and
the Common Facilities or any part thereof as contemplated by the
Transaction Documents, or (iii) the valid transfer, grant or assignment (as
the case may be) of the rights, title, interests and estate to be
transferred, granted and assigned pursuant to the Transaction Documents. 
The statements made and information provided by or on behalf of the SPV or
Lime, as the case may be, in connection with each such Governmental
Approval were true, complete and correct in all material respects when
made.  Annex 4 hereto lists all other material Governmental Approvals which
will be necessary to obtain prior to the commencement of commercial
operation of the Project (and the SPV has no reason to believe that such
Governmental Approvals will not be obtained prior to the Conversion Date). 
To the SPV's knowledge, no Governmental Approvals are required to enable
you, the Collateral Agent and the Disbursement Agent to participate in the
transactions contemplated by this Agreement and the other Transaction
Documents, prior to acquiring the Project through foreclosure or
conveyance or transfer in lieu of foreclosure.  All Governmental 
<PAGE>                                -10-<PAGE>
Approvals with respect to which a public hearing was necessary have been
duly issued, and any appeal period with respect to such issuance has
expired.

      Section 4.6 Tax Returns.  Each of the Partners and the SPV has filed
all Federal, state and local income, franchise and other tax returns, if any,
required to be filed by it on or prior to the date hereof, and has paid any
Taxes shown to be due and payable on such returns; Lime has paid (or caused
to be paid) all other Taxes in respect of the Project and the Site to the
extent the same have become due and payable and before they have become
delinquent.

      Section 4.7 Compliance with Law.  Each of the Partners and the SPV is
in compliance in all material respects with all Applicable Laws. 

      Section 4.8 Title to the Project, etc.   

            (a)   The descriptions of the Project Land set forth in the
      Ground Lease and the description of the Easement Parcel as set forth
      in the Easement Agreement are true, correct and sufficiently
      complete to identify such Property and to convey and encumber the
      same as contemplated by this Agreement and the other Transaction
      Documents.

            (b)   The Site, the Common Facilities and the Project conform in
      all material respects to all covenants, conditions, restrictions,
      reservations, and all zoning, environmental, subdivision control, land
      use and other applicable Federal, state and local laws, rules,
      regulations and ordinances, affecting any of the foregoing.

            (c)   The SPV has a good, valid and marketable (x) leasehold
      estate in and to the Project Land pursuant to the Ground Lease, (y)
      easement and use rights in and to the Easement Parcel and the Black
      River Common Facilities in accordance with the terms of the Easement
      Agreement, and (z) fee title in and to the Project, free and clear of
      all Liens (other than Permitted Encumbrances), and such Permitted
      Encumbrances do not impair or interfere with (A) the marketability of
      the Project, the Project Land, the SPV's rights in and to the Easement
      Parcel or the leasehold estate created under the Ground Lease, or (B)
      the maintenance of the Project, the Site or the Black River Common
      Facilities or the construction, testing, ownership, leasing, use,
      possession, operation or maintenance of the Project, the Site or the
      Black River Common Facilities.

            (d)   The SPV Collateral is not subject to any Lien, except for
      Permitted Encumbrances and Liens contemplated by the Transaction
      Documents. 

      Section 4.9 No Events of Default.  Neither the SPV nor Lime is in
default with respect to any of its obligations hereunder or under any
Transaction Document.  No condition exists that would, upon consummation of
the transactions contemplated hereby and by the other Transaction
Documents, constitute a Default or an Event of Default.  Lime is not in
default under any of the Existing Creditors Loan Documents.

      Section 4.10      Full Disclosure.  Neither this Agreement or any
other Transaction Document, nor any certificate, document, or financial
statement (other than the Projections) or other written information
furnished to you by Lime, the SPV or any Partner in connection with the
transactions contemplated hereby, contains any untrue statement of a
material fact or omits to 
<PAGE>                                -11-<PAGE>
state any material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading or that
could materially and adversely affect Lime, the SPV, you, the Project, the
Common Facilities or the Site.  All written factual information delivered by
Lime or the SPV or any Partner to the Independent Engineer was true,
accurate and complete in all material respects at the time supplied and did
not fail to state any material fact necessary to make the information
supplied, in light of the circumstances under which it was made, not
misleading.  The Projections have been prepared in good faith, to the best
knowledge of the SPV, by Continental Bank Lease Capital Group, and
approved in good faith by each of the SPV and Lime, and are based upon (i)
assumptions that the SPV believes are reasonable and (ii) the best
information available from the management of Lime at the time of the
preparation of such Projections.  The SPV has no reason to believe that the
Projections are false or misleading in any material respect.

      Section 4.11      Financial Statements of the Corporation and Lime.  The
copies of the financial statements of the Corporation and Lime delivered to
you pursuant to Section 5.27 are complete and correct in all material
respects and fairly present the Corporation's and Lime's financial position
as of the dates thereof, and the results of their respective operations
for the periods therein indicated, all in conformity with GAAP consistently
applied (except as stated therein or in the notes thereto).

      Section 4.12      Absence of Material Contingencies.   Neither the SPV
nor any Partner has any contingent liability other than those created
pursuant to the Transaction Documents.

      Section 4.13      Material Patents and Licenses.  The SPV owns,
possesses or is duly licensed for a period ending after the Term Note
Maturity Date in respect of all patents, trade secrets, processes,
trademarks, service marks, trade names, copyrights and licenses and rights
as are necessary for the commercial operation of the Project, without any
conflict with the rights of other Persons and without any obligation to pay
royalties or license fees therefor.

      Section 4.14      Taxes.   None of the acquisition, installation,
construction, maintenance, financing, use, conveyance or operation of the
Project, the Project Land, the Black River Common Facilities, or the
execution, recordation or filing of any Transaction Document by the
respective parties thereto, or the consummation of any of the transactions
contemplated hereby or thereby, will result in any tax, levy, impost, duty,
charge or withholding imposed as of the Initial Funding Date or Conversion
Date, with respect to the respective transactions to be consummated on
such dates, by the United States or the Commonwealth of Kentucky or any
other taxing Governmental Authority or political subdivision thereof,
except for: (i) transfer taxes and registration, recordation and other
miscellaneous fees payable in connection with the recordation or filing of
the Transaction Documents described on Part 4.14 of Annex 3 attached
hereto to be so recorded or filed, all of which taxes and fees shall have
been paid in full when due on or prior to the Initial Funding Date or the
Conversion Date, as the case may be, pursuant to Section 15 hereof; (ii)
Kentucky real and personal property taxes on its Property, including
without limitation, the Project; and (iii) franchise and other similar taxes
for which the SPV and Lime are responsible.

      Section 4.15      Utilities.   All electrical, telephone, water,
sanitary, septic or water treatment system and other utility services
necessary for the construction, use, operation and maintenance of the
Project, the Site and the Black River Common Facilities are available to the
Project, the Site 
<PAGE>                                -12-<PAGE>
and the Black River Common Facilities pursuant to the Ground Lease, the
MCFA, the Easement Agreement or other public or private easement or use
rights.

      Section 4.16      Easements, Servitudes, Rights of Way, etc.  All roads,
easements, servitudes, rights of way and other rights of ingress and
egress as are necessary for the installation, construction, completion,
testing, operation, maintenance and use of the Project, the Site and the
Black River Common Facilities have been obtained pursuant to the Ground
Lease, the MCFA, the Easement Agreement or other public or private
easement or use rights and are not adversely affected by any of the
Permitted Encumbrances in any material respect.

      Section 4.17      Status of Project Contracts.   The Project Contracts
are in full force and effect, in each case as required for the installation,
construction, completion, testing, operation, maintenance and use of the
Project, and the SPV or Lime, on the SPV's behalf, has complied with all
agreements and conditions, if any, to be performed or satisfied by it or
Lime thereunder on or before the date hereof in all material respects.  To
the best of the SPV's knowledge, after due inquiry, there is no default on
the part of any party under any Project Contract and no default has
occurred and is continuing which has not been cured or been waived by the
relevant party to such documents.  To the SPV's knowledge, each of Lime and
the SPV will be able to comply with all of the terms and conditions of the
Project Contracts to which such Person is a party.  Other than the
Transaction Documents to which the SPV is a party, the SPV is not a party
to, nor is any Property of the SPV bound by, any other material agreement.

      Section 4.18      Collateral Documents.  The SPV Security Agreement
and the Project Mortgage are effective to create a legal, valid and
enforceable Lien upon the SPV Collateral in favor of the Collateral Agent,
and upon proper recording or filing in the locations set forth in Part 4.18
of Annex 3 attached hereto (or, in the case of collateral a Lien on which
must be perfected by possession, delivery of such collateral to the
Collateral Agent), the Collateral Agent will have a first-priority perfected
Lien in the SPV Collateral.  No further action is required to establish a
valid and enforceable, first-priority Lien (subject to Permitted Liens) in
and to the SPV Collateral in favor of the Collateral Agent.

      Section 4.19      Substantial Completion Date.   The SPV has no reason
to believe that the Substantial Completion Date will not occur on or before
June 30, 1995.

      Section 4.20      Independent Engineer's Certificate.   To the best of
the SPV's knowledge, the statements set forth in the Independent
Engineer's Certificate described in Section 5.7 are correct in all material
respects and the SPV is not aware of any fact which could reasonably be 
expected to make such statements materially untrue, incorrect or
incomplete.

      Section 4.21      ERISA.  

                  a.    Prohibited Transactions.  Neither the execution of
      any Transaction Document nor the purchase of the Construction Notes
      by you will constitute a "prohibited transaction" (as defined in
      section 406 of ERISA or section 4975 of the Code).
<PAGE>                                -13-<PAGE>
                  b.    Compliance with ERISA.  Each of the Corporation, Lime
      and the SPV are in compliance with ERISA, except for such failures to
      comply that, individually or in the aggregate, could not reasonably be
      expected to have a material adverse effect on the business,
      prospects, profits, Properties or condition (financial or otherwise) of
      such Persons or on the Project.

                  c.    Funding Status.  No "accumulated funding deficiency"
      (as defined in section 302 of ERISA and section 412 of the Code)
      exists with respect to any Pension Plans of the Corporation, Lime or
      the SPV.  No ERISA Affiliate has an accumulated funding deficiency
      that could reasonably be expected to have a material adverse effect
      on the business, prospects, profits, Properties or condition
      (financial or otherwise) of such Persons or on the Project.

                  d.    PBGC.  No liability to the PBGC has been or is
      expected to be incurred by any of the Corporation, Lime or the SPV or
      any ERISA Affiliate of any such Persons with respect to any Pension
      Plan that, individually or in the aggregate, could reasonably be
      expected to have a material adverse effect on the business,
      prospects, profits, Properties or condition (financial or otherwise) of
      such Persons or on the Project.  No circumstance exists that
      constitutes grounds under section 4042 of ERISA entitling the PBGC
      to institute proceedings to terminate, or appoint a trustee to
      administer, any Pension Plan or trust created thereunder, nor has
      the PBGC instituted any such proceeding.

                  e.    Multiemployer Plans.  Neither the Corporation, Lime
      or the SPV, nor any ERISA Affiliate has incurred or presently expects
      to incur any withdrawal liability under Title IV of ERISA with respect
      to any Multiemployer Plan that could reasonably be expected to have a
      material adverse effect on the business, prospects, profits,
      Properties or condition (financial or otherwise) of such Persons or on
      the Project.  There have been no "reportable events" (as defined in
      section 4043 of ERISA) with respect to any Multiemployer Plan that
      could result in the termination of such Multiemployer Plan and give
      rise to a liability of the Corporation, Lime or the SPV or any ERISA
      Affiliate in respect thereof that could reasonably be expected to
      have a material adverse effect on the business, prospects, profits,
      Properties or condition (financial or otherwise) of such Persons or on
      the Project.

                  f.    Existing Pension Plans.  Part 4.21(f) of Annex 3
      hereto sets forth a complete and accurate listing of all ERISA
      Affiliates, and all employee benefit plans, plans and trusts
      maintained by any one or more of them, indicating in each case
      whether any of such employee benefit plans, plans or trusts have
      contracts with Prudential.

      Section 4.22      Environmental Matters.  Each of the SPV and Lime has
at all times complied in all material respects with all Environmental Laws
and the requirements of any permits issued under such Environmental Laws
with respect to the Site and the Project.  To the SPV's knowledge, there are
no circumstances that may hinder, delay, interfere with or prevent the
installation, ownership, construction, testing, maintenance and operation
of the Project or the use of the Site, as contemplated by the Transaction
Documents, in full compliance with applicable Environmental Laws.  All
material Governmental Approvals required under Environmental Laws to
install, construct, test, maintain and operate the Project are completely
and accurately listed 
<PAGE>                                -14-<PAGE>
in Annex 4 hereto, together with the name in which such Governmental
Approval must be issued.  Except as disclosed on Part 4.22 of Annex 3
hereto, there are no past, pending or, to the SPV's knowledge, threatened
Environmental Claims against Lime, the SPV, the Project, the Site or any of
the Black River Common Facilities.  Since the Site has been owned by Lime
and, to the SPV's knowledge, before the Site was owned by Lime, Hazardous
Materials have not been generated, used, treated, located or stored on, or
transported to or from, the Site, the Black River Common Facilities or the
Project, and the SPV has not used, and does not intend to use, nor permit,
any portion of the Site, the Black River Common Facilities or the Project

properly constructed on the Site in good and workmanlike manner and, in all
material respects, in accordance with the Plans and Specifications and
Applicable Law and in a manner that will allow it to be operated and
maintained in accordance with the Transaction Documents.  The SPV has no
reason to believe that the Project does not or will not have the capacity
and functional ability to perform, on a continuous basis, the functions and
the capacity for which it was designed.  The SPV is not aware of any event
or condition existing which presently adversely affects or is likely in the
future to adversely affect, such design, construction, equipping,

real property and other rights necessary for the construction, operation,
maintenance, repair, testing, use, possession and ownership of the Project,
have been validly obtained and are in full force and effect.  The SPV does
not have any reason to believe that there will be contractual or, based
upon Applicable Law, other legal rights required for such occupancy, use,
possession, ownership, operation and maintenance of the Site, the Project
and the Black River Common Facilities, or that there will be other services
or materials required for such operation, maintenance, use, occupancy and

provision, the SPV authorizes and directs the SPV's accountants to discuss
such matters with any such Person), all at such reasonable times and as
often as may be reasonably required; provided, however, that if a Default
or Event of Default shall have occurred and be continuing, the SPV shall be
responsible for the cost and expense incurred in respect of any such
inspection made by any such Person pursuant to this Section 10.6. Neither
the Collateral Agent nor you shall have any duty whatsoever to make any
inspection or inquiry referred to in this Section 10.6 and shall not incur
any liability or obligation by reason of not making such inspection or
inquiry.  You shall keep confidential any information with respect of the
SPV or the Project which the SPV indicates in writing at the time such
information is supplied is to be treated confidentially in compliance with
Section 17.5 of this Agreement.

SECTION 11  CASUALTY; CONDEMNATION.

      Section 11.1      Notice of Damage or Loss.  If any part or portion of
the Site, the Project or the Black River Common Facilities suffers any Loss
Event, the SPV shall promptly, and in any case within 5 Business Days after
such event, so notify the Holders, the Independent Engineer and the
Collateral Agent.

      Section 11.2      Repair.  Upon the occurrence of any Loss Event
(other than a Total Loss), the SPV shall cause the affected Property to be
repaired or replaced to the condition required by Section 9.6 as soon as
practicable but in any event within 180 days from the date of the
occurrence of such Loss Event; provided, however, that if, within such 180-
day period the SPV shall have commenced the repair or replacement of such
Property and shall be diligently pursuing such repair or replacement, but is
unable to complete the same within such 180-day period (in which case the
SPV shall so notify the Holders and the Collateral Agent), then the time for
repair or replacement shall be extended for such longer period as shall be
determined by the Independent Engineer to be necessary to complete such
repair or replacement, provided further that if the SPV shall fail to repair
or replace the Project within such period (including any 
<PAGE>                                -41-<PAGE>
extension thereof as provided above), such failure shall be deemed an
Event of Default hereunder.

      Section 11.3      Application of Payments on Total Loss.  Payments
received by the Collateral Agent or the SPV from any Governmental
Authority, insurer or other Person in respect of a Total Loss shall be paid
to the Disbursement Agent for deposit into the Windup Account.

      Section 11.4      Application of Payments Relating to a Partial Loss. 
Payments received by the Collateral Agent or by the SPV from any
Governmental Authority, insurer or other Person with respect to any
Partial Loss, shall be paid to the Disbursement Agent for deposit into the
Casualty Account.

      and coverage provisions sufficient to satisfy the requirements set
      forth in each of the Project Contracts, but in no event less than the
      limits and coverage provisions set forth below:

            the SPV has employees, workers' compensation insurance as
            required by applicable state laws including employer's liability

            policies with respect to which shall include Longshoremen's and
            Harbor Workers' Compensation Act insurance.

                  (ii)  General Liability Insurance.  Liability insurance on
            an occurrence basis against claims for personal injury
            (including bodily injury and death) and property damage.  Such
            insurance shall provide coverage for products-completed
            operations, blanket contractual, explosion, collapse and
            underground coverage, broad form property damage, personal
            injury insurance, and hostile fire liability with a $1,000,000
            minimum limit per occurrence for combined bodily injury and

            apply separately to claims occurring with respect to the
            Project.  A maximum self-insured retention or deductible of
            $250,000 shall be allowed.

                  (iii) Automobile Liability Insurance.  Automobile liability

            and unloading, with a $1,000,000 minimum limit per occurrence
            for combined bodily injury and property damage and containing
            appropriate no-fault insurance provisions wherever applicable.

<PAGE>                                -42-<PAGE>
                  (iv)  Excess Insurance.  Excess liability insurance on an
            occurrence basis covering claims in excess of the underlying
            insurance described in the foregoing subsections (i), (ii) and
            (iii), with a $19,000,000 minimum limit per occurrence, provided
            that aggregate limits of liability, if any, shall apply separately
            to claims occurring with respect to the Project.  The amounts of
            insurance required in the foregoing subsections (i), (ii), (iii) and
            this subsection (iv) may be satisfied by the SPV purchasing
            coverage in the amounts specified or by any combination
            thereof, so long as the total amount of insurance procured
            meets the requirements specified above.

                  (v)   Builder's Risk (Property) Insurance.  A builder's risk
            or property insurance policy on an "all risk" basis, including
            coverage against damage or loss caused by earth movement
            (including but not limited to earthquake, landslide, subsidence
            and volcanic eruption) and flood.  Such insurance shall be on a
            completed value form, with no periodic reporting requirements,
            insuring the Construction Costs and providing coverage for (a)
            insuring the buildings, structures, machinery, equipment
            (including electrical equipment), facilities, fixtures, supplies,
            fuel and other properties constituting a part of the Project, (b)
            off-site storage with sub-limits sufficient to insure the full
            replacement value of any property or equipment not stored at
            the Project, (c) removal of debris with a sub-limit not less than
            10 percent of the Construction Costs, (d) increased cost of
            construction and loss to undamaged property as the result of
            enforcement of building laws or ordinances with a sub-limit not
            less than 20 percent of the Construction Costs, (e) extra
            expenses in an amount not less than $2,000,000 and (f)
            foundations and other property below the surface of the
            ground. Such property damage insurance policy may also provide
            coverage for property damage and business interruption
            resulting from damage or loss to the Project or the Black River
            Facility caused by earth movement (including, but not limited to,
            earthquake, landslide, subsidence and volcanic eruption) and
            flood. The deductible for all such insurance shall not exceed
            $500,000 for earth movement and flood coverage and $50,000
            for all other coverage.  The policy is to insure electrical
            transmission lines and equipment to the extent the SPV has an
            insurable interest.  The ocean/air transit policy (which may be
            written separately) shall be on a "warehouse to warehouse"
            basis.  The builder's risk or property coverage shall not contain
            an exclusion for freezing, mechanical breakdown, loss or damage
            covered under any guaranty or warranty, or resultant damage
            caused by faulty workmanship, design or materials.  Coverage
            required by this clause (v) shall remain in effect until replaced
            by physical damage insurance as specified in Section 12.1(b)(i).
            The earth movement and flood coverages may be insured with a
            sub-limit not less than 80% of the "full insurable value" of the
            Project plus 80% of the Operating Expense amount required by
            Section 12.1(b)(ii) below, but in no case less than $50,000,000.

                  (vi)  Delayed Opening Insurance.  Delayed opening coverage
            in an amount equal to 12 months projected continuing expenses
            plus debt service of the SPV caused by damage or loss to any
            property required to be covered by clause (v) above.  The policy
            providing such coverage shall have a deductible of not greater
            than 10 days or, in the case of flood, a deductible of not
            greater than 
<PAGE>                                -43-<PAGE>
            $500,000.  Coverage shall remain in effect until replaced by
            business interruption insurance as specified in Section
            12.1(b)(ii).

            As respects the foregoing clauses (v) and (vi), subrogation is
            waived in favor of the SPV, the Collateral Agent, any Holder and
            their respective officers, agents and employees.  The policy(s)
            are to be endorsed to provide either an agreed amount clause or
            waiver of coinsurance and include as insured all contractors
            and the SPV.

            (b)   After Substantial Completion.  On or prior to the
      Substantial Completion Date, the SPV shall procure at its own expense
      and maintain in full force and effect, with responsible insurance
      companies authorized to do business in the Commonwealth of Kentucky
      with a Best Insurance Reports rating of "A-" or better and a financial
      size category of "IX" or higher (and other insurance companies
      acceptable to the Collateral Agent), with limits and coverage
      provisions sufficient to satisfy the requirements set forth in each
      of the Project Contracts, but in no event less than the limits and
      coverage provisions set forth below:

                  (i)   Physical Damage Insurance.  Property damage
            insurance on an "all risk" basis, including coverage against
            damage or loss caused by earth movement (including but not
            limited to earthquake, landslide, subsidence and volcanic
            eruption) and flood and providing coverage for (1) the Project in
            a minimum aggregate amount equal to the "full insurable value"
            of the Project, (2) transit, including ocean marine coverage if
            applicable, with sub-limits sufficient to insure the full
            replacement value of all property or equipment removed from
            the Project and insurance coverage while located off the
            Project, (3) electrical transmission lines along with related
            equipment including transformers, electric motors and
            electrical equipment, to the extent the SPV has an insurable
            interest, (4) foundations and other property below the surface
            of the ground, (5) soft costs defined as attorneys' fees,
            engineering and other consulting costs, and permit fees that
            may be incurred due to damage to the premises in a minimum
            amount of $1,000,000, and (6) extra expenses in an amount not
            less than $2,000,000. Such property damage insurance policy
            may also provide coverage for property damage and business
            interruption resulting from damage or loss to the Project and
            the Black River Facility caused by earth movement (including,
            but not limited to, earthquake, landslide, subsidence and
            volcanic eruption) and flood. For purposes of this Section
            12(b)(i), "full insurable value" shall mean the full replacement
            value of the Project, including any improvements, equipment,
            fuel and supplies, without deduction for physical depreciation
            and/or obsolescence. For all such insurance the deductible
            shall not exceed $50,000, except for the earth movement and
            flood coverage which shall have a deductible not exceeding
            $500,000.  Such insurance shall include an agreed amount
            clause or waiver of coinsurance and provide for increased cost
            of construction, debris removal, and loss to undamaged property
            as the result of enforcement of building laws or ordinances
            with sub-limits not less than 25% of the "full insurable value"
            of the Project.  The earth movement and flood coverages may be
            insured with a sub-limit not less than 80% of the "full
            insurable value" of the Project plus 80% of the Operating
            Expense amount required by Section 12.1(b)(ii) below, but in no
            case 
<PAGE>                                -44-<PAGE>
            
            less than $50,000,000.  The amount of physical damage and
            business interruption insurance with regard to impact damage
            to the docks located on the Easement Parcel shall be no less
            than $2,000,000.

                  (ii)  Business Interruption Insurance.  Business
            interruption insurance covering continuing normal operating
            expenses of the SPV including payroll and debt service
            ("Operating Expense") for a period of 12 months, arising from
            damage or loss insured by Section 12.1(b)(i) above.  The policy
            providing such coverage shall have a maximum deductible of not
            greater than 10 days or, in the case of flood, a deductible not
            greater than $500,000.  Such insurance shall also insure that
            portion of fixed expenses and debt service not earned arising
            from an insured loss or occurrence at the OPCO Gavin Power
            Station and the underground property at the Black River
            Facility for a period of four months.  Such insurance shall
            include either an agreed amount clause or waiver of
            coinsurance.

                  (iii)  Wharfingers Liability Insurance.  Wharfingers
            liability insurance covering liability arising out of the damage
            to or destruction of barges and vessels owned by others and
            the removal of wrecks with a $5,000,000 minimum limit per
            occurrence.

            (c)   Endorsements.  All policies of liability, physical damage and
      business interruption insurance to be maintained by the SPV shall
      provide for waivers of subrogation in favor of the Collateral Agent
      and the Holders and their respective officers and employees (and
      such other Persons as may be required by the Project Contracts).  All
      policies of liability insurance required to be maintained by the SPV
      under this Section 12.1 shall be endorsed as follows:

                  (i)   To provide a severability of interest or cross
            liability clause;

                  (ii)  That the insurance shall be primary and not excess
            to or contributing with any insurance or self-insurance
            maintained by the Collateral Agent or the Holders; and

                  (iii) To name the Collateral Agent and the Holders and
            their respective officers and employees (and such other
            Persons as may be required by the Project Contracts) as
            additional insureds.

            (d)   Waiver of Subrogation.  The SPV hereby waives any and
      every claim for recovery from the Holders for any and all loss or
      damage covered by any of the insurance policies to be maintained
      under this Agreement to the extent that such loss or damage is
      recovered under any such policy.  Inasmuch as the foregoing waiver
      will preclude the assignment of any such claim to the extent of such
      recovery, by subrogation (or otherwise), to an insurance company (or
      other Person), the SPV shall give written notice of the terms of such
      waiver to each insurance company which has issued, or which may
      issue in the future, any such policy of insurance (if such notice is
      required by the insurance policy) and shall cause each such
      insurance policy to be properly endorsed by the issuer thereof to, or
      to otherwise contain one or more provisions that, prevent the
      invalidation of the insurance coverage provided thereby by reason of
      such waiver.

      Section 12.2      Insurance By The Operator.  The SPV shall cause the
Operator to procure at its own expense and to maintain in full force and
effect at all times that the Project is being operated, with responsible
insurance companies authorized to do business in the Commonwealth of
Kentucky with a Best Insurance Reports rating of "A-" or better and a
financial size category of "IX" or higher (except for other companies
acceptable to the Collateral Agent), with limits and coverage provisions
sufficient to satisfy the requirements set forth in each of the Project
Contracts, but in no event less than the limits and coverage provisions set
forth below; however, the requirements of this Section 12.2 can also be
satisfied by naming the Operator as an insured on the insurance policies
procured by the SPV pursuant to the provisions of Section 12.1.

            (a)   General Liability Insurance.  Liability insurance on an
      occurrence basis against claims for personal injury (including bodily
      injury and death) and property damage.  Such insurance shall provide
      coverage for products-completed operations, blanket contractual,
      explosion, collapse and underground coverage, broad form property
      damage, personal injury insurance, and hostile fire liability with a
      $1,000,000 minimum limit per occurrence for combined bodily injury and
      property damage, provided that policy aggregates, if any, shall apply
      separately to claims occurring with respect to the Project.  A maximum
      self-insured retention or deductible of $250,000 shall be allowed.

            (b)   Automobile Liability Insurance.  Automobile liability
      insurance against claims for personal injury (including bodily injury
      and death) or property damage arising out of the use of all owned,
      leased, non-owned and hired motor vehicles, including loading and
      unloading, with a $1,000,000 minimum limit per occurrence for combined
      bodily injury and property damage and containing appropriate no-
      fault insurance provisions where applicable.  A maximum self-insured
      retention or deductible of $100,000 shall be allowed.

            (c)   Workers' Compensation Insurance.  Workers' compensation
      insurance as required by applicable state laws, including employer's
      liability insurance for all employees of the Operator with a
      $1,000,000 minimum limit per accident, the policies with respect to
      which shall include Longshoremen's and Harborworkers' Compensation
      Act insurance.

            (d)   Excess Insurance.  Excess liability insurance on an
      occurrence basis covering claims in excess of the underlying
      insurance described in the foregoing subsections (a), (b) and (c), with
      a $19,000,000 minimum limit per occurrence, provided that aggregate
      limits of liability, if any, shall apply separately to claims occurring
      with respect to the Project.

      The amounts of insurance required in the foregoing subsections (a),
      (b), (c) and this subsection (d) may be satisfied by the Operator
      purchasing coverage in the amounts specified or by any combination
      thereof, so long as the total amount of insurance meets the
      requirements specified above.

            (e)   Endorsements.  All policies of liability insurance to be
      maintained by the Operator shall provide for waivers of subrogation
      in favor of the SPV, the Collateral Agent, the Holders and their
      respective officers and employees (and such other Persons as may be
      required by the Project Contracts).  These policies shall also be
      endorsed as follows:
<PAGE>                                -46-<PAGE>
                  (i)   To provide a severability of interests or cross
            liability clause;

                  (ii)  That the insurance shall be primary and not excess
            to or contributing with any insurance or self-insurance
            maintained by the SPV, the Collateral Agent or the Holders; and

                  (iii) To name the SPV, the Collateral Agent, the Holders
            and their respective officers and agents (and such other
            Persons as may be required by the Project Contracts) as
            additional insureds.

      Section 12.3      Amendment of Requirements.  The Collateral Agent may
at any time amend the requirements and approved insurance companies of
this Section 12 due to (i) new information not known by the Collateral Agent
on the Initial Funding Date or (ii) changed circumstances after the Initial
Funding Date which in the reasonable judgment of the Collateral Agent
either renders such coverage materially inadequate or materially reduces
the financial ability of the approved insurance companies to pay claims.

      Section 12.4      Application of Proceeds.  All insurance proceeds
recovered by the Collateral Agent as aforesaid on account of a Loss Event
shall be applied pursuant to Sections 11.3 and 11.4 of this Agreement.  If the
aggregate damage or loss to (i) the Black River Facility and (ii) the Project
caused by an event of earth movement and/or flood is in excess of the
collectible insurance available to the SPV, the proceeds of the property
damage insurance paid out in respect of such event of earth movement
and/or flood  shall be allocated proportionately to the Owner (or its
assigns) and to the SPV in the amounts which reflect the percentage of the
total loss attributable to the Black River Facility and the Project,
respectively.  If the insurance policies providing coverage for earth
movement and flood also insure facilities other than the Project and the
Black River Facility, then the proceeds of the collectible property damage
insurance paid out in the event of damage or loss due to earth movement or
flood shall be allocated to the Project and the Black River Facility up to
100% of their loss or damage before any proceeds are allocated to the other
insured facilities.

      Section 12.5      Conditions.

            (a)   The SPV shall promptly notify the Collateral Agent of any
      loss covered by any insurance maintained pursuant to Section 12.1 or
      Section 12.2.

            (b)   All policies of insurance required to be maintained
      pursuant to Sections 12.1(a)(v) and (vi), (b)(i) and (ii), shall
      provide that the proceeds of such policies shall be payable to the
      Collateral Agent pursuant to a standard first mortgage endorsement
      substantially equivalent to the lender loss payable endorsement
      438BFU, without contribution; provided that if the proceeds thereof
      are less than $250,000, such proceeds shall be paid to the SPV.  The
      Collateral Agent shall have the right to join the SPV in adjusting any
      loss in excess of $250,000.  All policies (other than in respect to
      liability or workers' compensation insurance) shall insure the
      interests of the Holders regardless of any breach or violation by the
      SPV of warranties, declarations or conditions contained in such

      against the SPV, the Holders or the Operator, and shall waive any

      loss payable endorsement required above).

            (c)   All policies of insurance required to be maintained
      pursuant to this Section 12 shall be endorsed so that if at any time

      interests of the Holders, such cancellation or reduction shall not be
      effective as to the Holders for 60 days, except for non-payment of
      premium which shall be for 10 days, after receipt by the Collateral

and on an annual basis at least 10 days prior to each policy anniversary,
the SPV shall furnish the Collateral Agent with approved certification of
all required insurance.  Such certification shall be executed by each
insurer or by an authorized representative of each insurer where it is not
practical for such insurer to execute the certificate itself.  Such
certification shall identify underwriters, the type of insurance, the
insurance limits and the policy term and shall specifically list the special
provisions enumerated for such insurance required by this Section 12. 
Upon request, the SPV will promptly furnish the Collateral Agent with copies
of all insurance policies, binders and cover notes or other evidence of
such insurance relating to the Project.

of the certification referred to in Section 12.6 and at least 10 days prior
to the expiration of any insurance policy required of the SPV, the SPV shall
furnish the Collateral Agent with a certificate signed by a Responsible
Officer of the SPV and by a Responsible Officer of the Insurance
Consultant stating that in the opinion of such Responsible Officer, the
insurance then carried or to be renewed is in accordance with the each
terms of this Section 12.

      Section 12.8      Failure to Maintain Insurance.  In the event the SPV
fails, or fails to cause the Operator, to take out or maintain the full
insurance coverage required by this Section 12, the Collateral Agent, upon
30 days' prior notice (unless the aforementioned insurance would lapse
within such period, in which event notice should be given as soon as
reasonably possible) to the SPV of any such failure, may (but shall not be
obligated to) take out the required policies of insurance and pay the
premiums on the same.  All amounts so advanced in respect thereof by the
Collateral Agent shall become an additional obligation of the SPV to the
Collateral Agent, and the SPV shall forthwith pay such amounts to the
Collateral Agent, together with interest thereon at the Late Payment Rate
from the date so advanced.

      Section 12.9      No Duty of the Collateral Agent to Verify.  No
provision of this Section 12 or any other provision of this Agreement shall
impose on the Collateral Agent any duty or obligation to verify the
existence or adequacy of the insurance coverage maintained by the SPV,
nor shall the Collateral Agent be responsible for any representations or
warranties made by or on behalf of the SPV to any insurance company or
underwriter.

      Section 12.10  Maintenance of Insurance.  The SPV shall at all times
maintain the insurance coverage required under the terms of the Project

            Section 13.1 shall exist, all of the Notes shall automatically

            accrued thereon and, to the extent permitted by law, the Make-
            Whole Amount at such time with respect to the principal amount
            of such Notes, without presentment, demand, protest or notice
            of any kind, all of which are hereby expressly waived;

      right of each Holder to maintain its investment in the Notes free

      for) is a valuable right, and that the provision for payment of a
      Make-Whole Amount by the SPV under certain circumstances if the
      Notes are paid or prepaid, or are accelerated as a result of an Event
      of Default, is intended to provide compensation for the deprivation
      of such right under such circumstances.

            (c)   Expenses.  If the SPV shall fail to pay when due any
      principal of, or Make-Whole Amount or interest on, any Note, or shall

      the Collateral Agent or the Holders, to the extent permitted by law,
      such further amounts as shall be sufficient to cover the costs and
      expenses, including, but not limited to, reasonable attorneys' fees,
      incurred by the Collateral Agent and such Holders in collecting any
      sums due on the Notes or such obligations or in otherwise assessing,
      analyzing, evaluating, protecting, asserting, defending or enforcing
      any of the rights and remedies that are or may be available to the
      Collateral Agent or any such Holder.

      Section 13.3      Remedies.

      If an Event of Default exists, without limitation of any other rights
and remedies which may be available to any Holder, the Required Holders
may, in accordance with the Collateral Agency Agreement, cause the
Collateral Agent to exercise any and all remedies available to it under the
SPV Security Agreement, the Project Mortgage or any of the other
Transaction Documents.  Each Holder may take all steps necessary or
advisable to protect and enforce its rights hereunder, whether by action,
suit or proceeding at law or in equity, for the specific performance of any
covenant, condition or agreement contained herein, or in aid of the
execution of any power herein granted, or for the enforcement of any other
appropriate legal or equitable remedy or otherwise as such Holder shall
deem necessary or advisable.

      No right or remedy hereunder shall be exclusive of any other right,
power or remedy, but shall be cumulative and in addition to any other right
or remedy hereunder or now or hereafter existing by law or in equity and
the exercise by a party hereto of any one or more of such rights, power or
remedies shall not preclude the simultaneous exercise of any or all of such
other rights, powers or remedies.  Any failure to insist upon the strict
performance of any provision hereof or to exercise any option, right, power
or remedy contained herein shall not constitute a waiver or relinquishment
thereof for the future.

SECTION 16  REGISTRATION; SUBSTITUTION OF TERM NOTES.

      Section 16.1      Registration of Notes.

      The SPV shall maintain a register for the registration and transfer
of the Notes at its chief executive office set forth in Section 4.35.  The
name and address of each Holder, the type of Note held, each transfer
thereof and the name and address of each transferee of one or more Notes
shall be registered in the register.  The Person in whose name any Note
shall be registered shall be deemed and treated as the owner and holder
thereof for all purposes hereof, and the SPV shall not be affected by any
notice or knowledge to the contrary.  

      Section 16.2      Exchange of Notes.

      Upon surrender of any Note at the office of the SPV, duly endorsed or
accompanied by a written instrument of transfer duly executed by the
registered holder of such Note or his attorney duly authorized in writing,
the SPV shall execute and deliver, at the SPV's expense (except as provided
below), new Notes in exchange therefor, in such denominations as may be
requested by the surrendering holder (but not less than Fifty Thousand
Dollars ($50,000), except as may be necessary to reflect any principal
amount not evenly divisible by Fifty Thousand Dollars ($50,000)), in an
aggregate principal amount equal to the unpaid principal amount of the
surrendered Note.  Each such new Note shall be payable to such Person as
such holder may 
<PAGE>                                -56-<PAGE>
request and shall be substantially in the form of the Note surrendered. 
Each such new Note shall be dated and bear interest from the date to which
interest shall have been paid on the surrendered Note or dated the date of
the surrendered Note if no interest shall have been paid thereon.  The SPV
may require payment of a sum sufficient to cover any stamp tax or
governmental charge imposed in respect of any such transfer of Notes. 

      Section 16.3      Replacement of Notes.

      Upon receipt by the SPV of evidence reasonably satisfactory to it of
the ownership of and the loss, theft, destruction or mutilation of any Note
(which evidence shall be, in the case of an Institutional Investor, notice
from such Institutional Investor of such ownership and such loss, theft,
destruction or mutilation) and

            (a)   in the case of loss, theft or destruction, of
      indemnity reasonably satisfactory to it (provided that if the
      holder of such Note is an Institutional Investor, such holder's
      own agreement of indemnity shall be deemed to be satisfactory),
      or

            (b)   in the case of mutilation, upon surrender and cancellation
      thereof,

the SPV at its own expense shall execute and deliver, in lieu thereof, a new
Note, dated and bearing interest from the date to which interest shall have
been paid on such lost, stolen, destroyed or mutilated Note or dated the
date of such lost, stolen, destroyed or mutilated Note if no interest shall
have been paid thereon.

      Section 17.2      General Indemnification. The SPV agrees (regardless
of whether (a) any of the transactions contemplated hereby are
consummated, (b) such Indemnitee shall also be indemnified as to such
Expense by any other Person (except to the extent the Indemnitee has
received payment from such other Person) or (c) such Expense arises or
accrues prior to the date of this Agreement), to defend, indemnify and make
whole each Indemnitee against, and to protect, save and keep harmless each
Indemnitee from, any and all Expenses that may be imposed on, incurred by
or asserted by any Person against, such Indemnitee, which Expenses are in
any way attributable or relating to or arising out of (i) the Project, the
Site, the MCFA, the Easement Agreement or any part thereof or interest
therein; (ii) any of the Transaction Documents (or any other agreement,
contract or instrument entered into in connection therewith or related
thereto) or any of the transactions contemplated thereby or the exercise
by any Indemnitee of remedies thereunder, and (iii) the construction,
financing, acquisition, ownership, possession, use, regulation, operation,
maintenance and condition of all or any part of or any interest in the Site,
the Project or the Black River Common Facilities or the imposition of any
Lien thereon, including, in each case, without limitation (and whether the
subject of litigation or not) (but without duplication of any Construction
Costs or liquidated damages which Lime is obligated to pay):  (A) claims or
penalties arising from any product liability, negligence, statutory liability
or violation of Applicable Law or in tort (strict, absolute or otherwise), (B)
Environmental Claims or other loss of or damage to any property or the
environment (including, without limitation, all Expenses associated with
remediation, response, removal, corrective action, financial assurance,
natural resource damages and the protection of wildlife, aquatic species
and vegetation, and any relevant mitigative action required under
applicable Environmental Laws), or death or injury to any Person, (C) latent
or other defects, whether or not discoverable, (D) the breach by Lime or the
SPV of any representations or warranties, or the failure by Lime or the
SPV to perform or observe any covenants or agreements, under any
Transaction Document (or any other agreement, contract or instrument
entered into in connection therewith or related thereto); and (E) any claim
for patent, trademark or copyright infringement; provided, however, that
the foregoing indemnity shall not extend to any Expense imposed on,
incurred by or asserted against any Indemnitee to the extent the same (y)
constitutes an Expense which such Indemnitee is expressly liable for
payment of hereunder or under any other Transaction Document or (z)
relates to or arises the willful misconduct or gross negligence of such
Indemnitee or of its agents, officers, directors or employees.

      If the SPV shall obtain knowledge of any Expense indemnified against
under this Section  17.2, it shall give prompt written notice thereof to the
appropriate Indemnitee or Indemnitees, and if any Indemnitee shall obtain
any such knowledge, such Indemnitee shall give prompt written notice
thereof to the SPV, but failure of any Indemnitee to give notice shall not
affect the obligations of the SPV in respect thereof.  With respect to any
Expense that the SPV is requested by an Indemnitee to pay by reason of
this Section 17.2, such Indemnitee shall, if so requested by the SPV and
prior to any payment, submit such additional information to the SPV as the
SPV may reasonably request to substantiate the requested payment.

      In case any action, suit or proceeding shall be brought against any
Indemnitee, such Indemnitee shall promptly notify the SPV of the
commencement thereof (but the failure to do so shall not relieve the SPV of
its obligation to indemnify such Indemnitee except to the extent that the
SPV is prejudiced as a result of such failure), and the SPV, so long as no
Default or Event of Default shall have then occurred and be continuing,
shall be entitled, at its expense, acting through counsel reasonably
acceptable to such Indemnitee, to participate in, and, to the extent 
<PAGE>                                -58-<PAGE>
that the SPV desires (if the SPV has acknowledged in writing its obligations
hereunder to indemnify fully such Indemnitee with respect to all such
Expenses under this Section 17.2) to assume and control the defense
thereof; provided, however, that the SPV shall not be entitled to assume
and control the defense of any such action, suit or proceeding if and to the
extent that, in the reasonable discretion of such Indemnitee, (i) such
action, suit or proceeding involves the possible imposition of criminal
liability on such Indemnitee, (ii) such action, suit or proceeding involves a
reasonable likelihood of the imposition of civil liability on such Indemnitee
which the SPV is not obligated to indemnify hereunder, (iii) such Indemnitee
determines, in its reasonable discretion, that it may raise a defense or
defenses which is or are unavailable to the SPV or different from the
defenses available to the SPV in such action, suit or proceeding, (iv) such
control and assumption, in the reasonable discretion of such Indemnitee,
involves a conflict of interest between such Indemnitee and the SPV or any
other Indemnitee with respect to such action or proceeding, or (v) such
action, suit or proceeding entails a reasonable possibility of compromising
or jeopardizing a substantial interest of such Indemnitee; and in any such
event such Indemnitee may retain additional and separate counsel to
represent it or, at its option, assume the defense of such action and the
SPV will pay all of the Expenses of such Indemnitee in respect of such
defense, provided that if the SPV shall not elect in writing to assume the
defense thereof to the extent entitled to do so, an Indemnitee may, after
written notice to the SPV and after the SPV's failure to remedy promptly
the same, assume the defense thereof, including the employment of counsel,
in which case the SPV shall pay all of the Expenses of such Indemnitee
incurred in respect of such defense.  An Indemnitee shall, in any case, be
entitled, at its expense, to participate in any action, suit or proceeding the
defense of which has been assumed by the SPV; provided however, that if
the SPV fails to employ counsel reasonably satisfactory to such Indemnitee
the fees and expenses of counsel to such Indemnitee shall be paid by the
SPV.

      No Indemnitee shall enter into any settlement or other compromise
with respect to any Expense without the prior written consent of the SPV
(which consent shall not be unreasonably withheld or delayed) unless such
Indemnitee waives its right to be indemnified under this Section 17.2 with
respect to such Expense or an Event of Default shall have then occurred
and be continuing.  In any action, suit or proceeding to which any Indemnitee
is a party, the SPV shall not enter into any settlement or other compromise
with respect to any Expense without the prior written consent of such
Indemnitee which consent shall not be unreasonably withheld or delayed.

      Upon payment of any Expense by the SPV pursuant to this Section 17.2
to or on behalf of an Indemnitee, the SPV, without any further action, shall
be subrogated to any and all claims that such Indemnitee may have to
recover such Expense from any other Person (other than claims in respect
of insurance policies maintained by such Indemnitee at its own expense),
and such Indemnitee shall cooperate with the SPV and give such further
assurances as are reasonably necessary or advisable to enable the SPV to
pursue such claims; provided that the SPV's rights of subrogation shall be
subordinated to the full and complete payment of all principal, interest,
Make-Whole Amount and other amounts due with respect to the Notes.

      Nothing in this Section 17.2 shall be construed as a guaranty by the
SPV of any residual or market value in the Project, the Project Land or of
the performance capability or operating capacity of the Project or as a
guaranty of any Notes.
<PAGE>                                -59-<PAGE>
      Section 17.3      Increased Costs.  If,

            (i)   the compliance by any Holder with any direction,
      requirement or request after the date hereof from any Governmental
      Authority, whether or not having the force of law, with which such
      Holder must reasonably comply (including, without limitation the
      National Association of Insurance Commissioners); or

            (ii)  the change in the interpretation or application of any law
      or the enactment of any law after the date hereof imposing or
      modifying any reserve requirement (including, without limitation, any
      requirement of the National Association of Insurance Commissioners),
      capital adequacy requirement or similar requirement with respect to
      any class of assets or liabilities of, deposits with or for the account
      of, or loans or investments by, any Holder (or with respect to any
      change therein or in the amount thereof); or

            (iii) the occurrence after the date hereof of any other
      condition or circumstance (other than conditions or circumstances
      relating only to such Holder and arising solely as a result of an
      exercise of discretion by such Holder) with respect to this Agreement
      and/or the maintenance by such Holder of its investment in the Notes,

shall (A) result in any increase in cost to any Holder in connection with or
arising out of any Note, (B) result in any reduction in the amount of any
payment receivable by any Holder hereunder or thereunder or (C) result in
any reduction of the rate of the return on any Holder's capital as a
consequence of its obligations hereunder below that which such Holder
could have achieved but for such circumstances, then, in each such case,
the SPV shall fully reimburse such Holder the amount of such increase in
cost, reduction in payment receivable or reduction in rate of return
promptly after written notification thereof to the SPV by such Holder,
which notification shall include such Holder's relevant calculations and all
relevant additional facts, assumptions and information that such Holder
customarily provides in like circumstances.  The Holders shall (consistent
with their internal policies and legal and regulatory restrictions) use
their reasonable efforts to avoid such increased costs by giving the SPV
prompt notice thereof.

      If at any time a Holder gives notice that any amount is due under this
Section 17.3, the SPV shall, for a thirty (30) day period following receipt of
such notice, have the right to prepay such Holder's Notes at par (without
any payment of the Make-Whole Amount).

      Section 17.4      Restriction on Sale of Notes.  So long as no Default
or Event of Default shall exist, no Holder shall sell any Note to (a) any
Person engaged in a business substantially similar to that of Lime on the
Initial Funding Date, or (b) any electric utility company.

      Section 17.5      Disclosure to Other Persons.  Each Holder shall use
its best efforts to hold in confidence and not to disclose any Confidential
Information, provided, that any Holder will be free, after notice to the SPV,
to correct any false or misleading information that may become public
concerning its relationship to the SPV or Lime or to the transactions
contemplated by this Agreement.  Notwithstanding the foregoing, the SPV
acknowledges that any Holder may deliver copies of any financial
statements and other documents delivered to such Holder, and disclose any
other information disclosed to such Holder (including, without limitation,
Confidential Information), by or on behalf of the SPV in connection with or
pursuant to this Agreement, to
<PAGE>                                -60-<PAGE>
            (a)   such Holder's directors, officers, employees, agents and
      professional consultants,

            (b)   any other Holder,

            (c)   any Institutional Investor to which such Holder sells or
      offers to sell such Note or any part thereof, provided that such
      Institutional Investor signs a written agreement to comply with the
      confidentiality provisions of this Agreement, regardless of whether
      or not such offeree purchases any Notes, and provided further that
      no such agreement shall be required so long as such Institutional
      Investor is furnished only with information that is not Confidential
      Information,

            (d)   any Institutional Investor to which such Holder sells or
      offers to sell a participation in all or any part of such Note,
      provided that such Institutional Investor signs a written agreement
      to comply with the confidentiality provisions of this Agreement,
      regardless of whether or not such offeree purchases any Notes, and
      provided further that no such agreement shall be required so long as
      such Institution Investor is furnished only with information that is
      not Confidential Information,

            (e)   any federal or state regulatory authority having
      jurisdiction over such Holder,

            (f)   the National Association of Insurance Commissioners or
      any similar organization or

            (g)   any other Person to which such delivery or disclosure may
      be necessary,

                  (i)   in compliance with any law, rule, regulation or order
            applicable to such Holder,

                  (ii)  in response to any subpoena or other legal process,
            or

                  (iii) in connection with any litigation to which such
            Holder is a party.

      Section 17.6      Reproduction of Documents.  This Agreement, each
other Transaction Document and all documents relating hereto or thereto,
including, without limitation,

            (a)   consents, waivers and modifications which may hereafter
      be executed,

            (b)   documents received by you in connection with any Advance
      (except the Notes themselves), and

            (c)   financial statements, certificates and other information
      previously or hereafter furnished to you or any other holder of
      Notes,

may be reproduced by you or any other Holder of Notes by any photographic,
photostatic, microfilm, micro-card, miniature photographic or other similar
process and each Holder may destroy any original document so reproduced. 
The SPV agrees and stipulates that any such 
<PAGE>                                -61-<PAGE>
reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by such Holder in
the regular course of business) and that any enlargement, facsimile or
further reproduction of such reproduction shall likewise be admissible in
evidence.

      Section 17.7      Payments on Notes; other Amounts.

            (a)   Manner of Payment.  The SPV shall make each payment of
      principal, interest, Make-Whole Amount and all other amounts due with
      respect to each Note (without any presentment of such Notes and
      without any notation of such payment being made thereon) by
      crediting, by federal funds bank wire transfer, your account
      designated on Annex 1 prior to noon New York City time on the date
      such payment is due.  

            (b)   Payments Due on Holidays.  If any payment due on, or with
      respect to, any Note shall fall due on a day other than a Business
      Day, then such payment shall be made on the first Business Day
      following the day on which such payment shall have so fallen due;
      provided that if all or any portion of such payment shall consist of a
      payment of interest, for purposes of calculating such interest, such
      payment shall be deemed to have been originally due on such first
      following Business Day, such interest shall accrue and be payable to
      (but not including) the actual date of payment, and the amount of the
      next succeeding interest payment shall be adjusted accordingly.  If
      any payment is to be made on the first Business Day following the day
      on which the same shall have fallen due, as provided in this
      paragraph, and is not so paid on such first Business Day, interest
      shall accrue thereon (to the extent permitted by applicable law) with
      respect to each Note at the rate provided in such Note on overdue
      payments of principal from (in each case) the originally scheduled day
      of its payment.

            (c)   Payments, When Received.  Any payment to be made to any
      Holders shall be deemed to have been made on the Business Day such
      payment actually becomes available to such Holder at such Holder's
      bank prior to noon (New York City time).

            (d)   Other Amounts.  Any fees, expenses, costs and other
      amounts due from the SPV to you  pursuant to this Agreement or any
      other Transaction Document which are not paid when due shall bear
      interest thereafter at a rate per annum equal to the Late Payment
      Rate.

      Section 17.8      Survival.  All warranties, representations,
certifications and covenants made by the SPV herein or in any certificate
or other instrument delivered by it or on its behalf under this Agreement
or any other Transaction Document shall be considered to have been relied
upon by you and shall survive the delivery to you of the Notes regardless
of any investigation made by you or on your behalf.  All statements in any
such certificate or other instrument shall constitute warranties and
representations by the SPV hereunder.

      Section 17.9      Successors and Assigns.  The SPV may not assign any
of its interests, rights or obligations hereunder without your prior written
consent.  This Agreement shall inure to the benefit of and be binding upon
the successors and permitted assigns of each of the parties hereto.  The
provisions of this Agreement are intended to be for the benefit of all
Holders 
<PAGE>                                -62-<PAGE>
and shall be enforceable by any such Holder, whether or not an express
assignment to such Holder of rights under this Agreement has been made by
you or your successor or assign.

      Section 17.10     Amendments.  The provisions of this Agreement may
not be waived, modified, amended, supplemented or terminated in any manner
whatsoever except by written instrument signed by each party against
which enforcement or applicability of the waiver, modification, amendment,
supplement or termination is sought.  

      Section 17.11     Section Headings, Table of Contents.  The titles of
the Sections and the Table of Contents appear as a matter of convenience
only, do not constitute a part hereof and shall not affect the construction
hereof.  The words "herein," "hereof," "hereunder" and "hereto" refer to
this Agreement as a whole and not to any particular Section or other
subdivision.

      Section 17.12     Duplicate Originals; Execution in Counterpart.  Two or
more duplicate originals of this Agreement may be signed by the parties,
each of which shall be an original but all of which together shall
constitute one and the same instrument.  This Agreement may be executed in
one or more counterparts and will be effective when at least one
counterpart has been executed and delivered by each party hereto; and
each set of counterparts which, collectively, shows execution by all of the
parties hereto shall constitute one duplicate original.

      Section 17.13     Jury Trial Waiver.      NEITHER THE SPV NOR THE
PURCHASER (NOR ANY OF THEIR RESPECTIVE SUCCESSORS OR ASSIGNS) SHALL SEEK A
JURY TRIAL IN ANY ACTION BASED UPON OR ARISING OUT OF OR OTHERWISE RELATING TO
THIS AGREEMENT, ANY OF THE FINANCING DOCUMENTS, ANY COLLATERAL FOR THE
INDEBTEDNESS EVIDENCED BY THE NOTES, OR THEIR DEALINGS OR RELATIONSHIPS WITH
EACH OTHER, AND EACH OF THEM AGREE THAT NO SUCH ACTION WITH RESPECT TO WHICH A
JURY TRIAL HAS BEEN WAIVED SHALL BE SOUGHT TO BE CONSOLIDATED WITH ANY OTHER
ACTION IN WHICH A JURY TRIAL CANNOT OR HAS NOT BEEN WAIVED.  THIS PARAGRAPH
HAS BEEN FULLY DISCUSSED BY THE SPV AND YOU, EACH OF WHOM HAVE BEEN
REPRESENTED BY COUNSEL, AND THIS PARAGRAPH SHALL NOT BE SUBJECT TO ANY
EXCEPTIONS.

                     MASTER COMMON FACILITIES AGREEMENT

    MASTER COMMON FACILITIES AGREEMENT (this "Agreement"), dated as of
August 1, 1994, between DRAVO LIME COMPANY, a Delaware corporation, as
Owner and Operator, and DRAVO BLACK RIVER LIMITED PARTNERSHIP, a Delaware
limited partnership.

                                        PRELIMINARY STATEMENTS

    1. Pursuant to the Ground Lease the SPV will acquire from Lime a
leasehold interest in the Project Land.  The SPV desires to complete
construction of the Project upon the Site.  Lime has assigned to the SPV
its rights under the Construction Contracts.  In addition, the SPV has
appointed Lime to act as construction manager of the Project pursuant to
the Construction Management Agreement.

    2. Lime, as owner of the Black River Facility (together with its
successors and permitted assigns as owner of the Black River Facility, in
such capacity, the "Owner"), desires (i) to provide certain facility
support and services and to supply limestone and other necessary items to
the Project and (ii) to serve as initial Operator of the Project.

    3. In exchange therefor and for other good and valuable consideration,
the SPV wishes to grant to the Owner the right to use the Project for the
processing of the Owner's limestone and the handling and storage of
processed lime.

    4. The parties hereto desire to enter into this Agreement, the Ground
Lease and various other Transaction Documents to establish their
respective rights and obligations in respect of the foregoing
arrangements.  For purposes of this Agreement, capitalized terms used
herein and not otherwise defined herein shall have the meanings assigned
to them in Annex A to the Note Purchase Agreement, dated as of August 1,
1994, between the SPV and the Lender.  The rules of usage set forth in
such Annex A shall apply hereto.

    NOW, THEREFORE, in consideration of the premises and of the mutual
agreements herein contained and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties
hereto hereby agree as follows:

ARTICLE 1.     OPERATION AND MAINTENANCE OF THE PROJECT

    1.1  Appointment of the Operator.   The SPV hereby appoints Lime as
sole operator of the Project (such sole Operator, in such capacity,
together with its successors and permitted assigns, being herein referred
to as the "Operator") from and after the date hereof until the termination
of this Agreement or until Lime shall have been removed in accordance with
Section 1.10.  Lime hereby agrees to serve as the initial Operator on the
terms and subject to the conditions of this Agreement.

    1.2  Operational Responsibilities and Obligations of the Operator.

            (a)  The Operator shall be responsible for providing all work and
    services with respect to the start-up, operation and maintenance of the
    Project and the operation and maintenance of the Black River Common
    Facilities as set forth in Schedule 1 and the other provisions of this
    Agreement (the "Operating Work").  Each of the parties hereto
    acknowledges and agrees that the Operator, in performing its duties
    hereunder, is acting as an independent contractor.

            (b)  Subject to Section 1.3, the Operator may enter into such
    agreements or subcontracts as the Operator, in compliance with Prudent
    Industry Practice, deems necessary or appropriate, or as may be
    required by Applicable Law, with respect to the Operating Work.  If any
    such agreement or subcontract (or modification thereof), except for any
    collective bargaining agreement, shall provide for the payment of more
    than $100,000 by any party thereto or shall refer to the SPV, the
    Lender or the Collateral Agent, such agreement or subcontract (or
    modification thereof) shall expressly provide that it does not impose
    on the SPV or any other party to a Transaction Document (other than the
    Operator) any obligation, liability or duty to any contractor or
    subcontractor or create any contractual relationship between any
    contractor or subcontractor and the SPV or any other party to a
    Transaction Document (other than the Operator).

            (c)  In fulfilling its obligations under this Article 1, the
    Operator shall not, except as otherwise expressly set forth herein
    (including Section 1.9 and Section 3.1(b) hereof), be required to take
    any action that would have the effect of discriminating against the
    Black River Facility or any other lime production facility owned by it
    or any of its Affiliates, or in the use of the Project or the Black
    River Common Facilities in connection therewith.  In addition, the
    Operator shall not take any action in connection with the operation of
    the Black River Processing Complex or any other lime production
    facility owned by it or any of its Affiliates that would have the
    effect of discriminating against the Project.  For purposes of this
    Section 1.2(c), "discriminating" means providing available supplies
    and/or services on any basis other than ratably, in accordance with
    then applicable production or maintenance requirements, among the
    Project and all lime production facilities operated by the Operator
    capable of servicing Compatible Lime Supply Agreements.

    1.3  Matters Requiring Approval.  The Operator shall not take any
action with respect to the Project except as set forth in Section 1.2 or
in the Easement Agreement.  In any case, and without limiting the
generality of the foregoing, the Operator shall not take any of the
following actions without the prior written consent of the SPV:

            (a)  any action the effect of which may be to reduce the
    production level at which the Project is capable of being operated for 
    Capability as of the Conversion Date unless such action is in
    consequence of an Operating Emergency as to which (i) the Operator
    shall have given the SPV, the Lender and the Independent Engineer
    notice setting forth the details of such Operating Emergency within 48
    hours after the occurrence of such event or circumstance ("Emergency
    Notice") and (ii) within one week after receipt of the Emergency Notice
    by the Independent Engineer, the Independent Engineer shall have agreed
    that such reduction in production level is, consistent with Prudent
    Industry Practice, necessary to 
<PAGE>                                -2-<PAGE>
    avoid or alleviate such Operating Emergency; provided, however, that
    any such reduction on account of an Operating Emergency shall be
    permitted for only such period of time as the Independent Engineer, in
    consultation with the Operator, shall deem appropriate, in accordance
    with Prudent Industry Practice;

            (b)  make any Capital Additions or Modifications, or any
    adjustments, alterations or other physical changes to the Project (i)
    the effect of which may be to reduce the Total Net Capability of the
    Project or (ii) which may be inconsistent with the obligations of the
    SPV under the Note Purchase Agreement (as in effect on the Initial
    Funding Date); provided, however, that in the case of any Capital
    Additions or Modifications, or any adjustment, alteration or other
    physical change of any kind whatsoever, which is consented to in
    writing by the SPV, the costs thereof shall not constitute Operation
    and Maintenance Costs, or be paid with Project Revenues, unless
    otherwise agreed in writing by the SPV; and provided, further, that no
    Capital Additions or Modifications or any adjustment, alteration or
    other physical change shall be made to the Project-Owned Common
    Facilities which could reasonably be expected to have a material
    adverse effect on the Black River Facility without the prior written
    consent of the holders of 66-2/3% in principal amount of the Existing
    Creditors Indebtedness;

            (c)  any action the effect of which could reasonably be expected
    to cause a Permanent Shutdown to occur;

            (d)  settlement of any dispute with a contractor or supplier in
    respect of goods or services contracted for by the Operator hereunder,
    if the amount involved is in excess of $250,000;

            (e)  other than for Operating Emergencies which are governed by
    Section 1.3(a), any action to take the Project out of service for any
    continuous period that (i) exceeds one week, (ii) when combined with
    all periods of voluntary outage of the Project not requiring consent
    under this Section 1.3(e) which shall have occurred in the 12-month
    period immediately preceding the date of any such action, would exceed
    in the aggregate three weeks, (iii) is not permitted pursuant to
    Section 1.5 or (iv) constitutes a Permanent Shutdown;

            (f)  the adoption of any Project Budget or Extended Budget, and
    any changes to either thereof; or

            (g)  make any material substitution, replacement or repair of any
    part or equipment incorporated into the Project.

Notwithstanding the foregoing, the scheduled recurring capital
expenditures referred to on Schedule 2 hereto shall constitute Operation
and Maintenance Costs.

    1.4  Operation and Maintenance Costs; Budget.

            (a)  (i)  At least 60 days prior to the beginning of each
            Contract Year, the Operator shall prepare and submit to the SPV,
            the Independent Engineer, the Existing Creditors, the Lender and
            the Owner, (A) a draft line item budget (the 
<PAGE>                                -3-<PAGE>
            "Draft Project Budget") setting forth by category the Operator's
            projections of the cost of operating the Project during the
            upcoming Contract Year, on a month by month basis, (B) detailed
            backup information sufficient to permit an informed review of
            such Draft Project Budget, and (C) the levels of projected lime
            purchases provided to the SPV by OPCO pursuant to Article III(c)
            of the OPCO Agreement.  Each Draft Project Budget and each
            Project Budget shall contain a separate line item for the costs
            of coal/petroleum coke, electricity, insurance, property taxes,
            labor, scheduled recurring capital expenses, and Other Costs
            based upon the projected levels of lime purchases provided to the
            SPV by OPCO pursuant to Article III(c) of the OPCO Agreement, all
            as more fully set forth on Schedule 2 hereto.  No Draft Project
            Budget or Project Budget shall provide for any Capital Additions
            or Modifications or any other items requiring prior written
            consent pursuant to Section 1.3 (unless such consent shall be
            granted).

                  (ii)  Within 45 days after its receipt of a Draft Project
            Budget for any Contract Year, the SPV and the Lender shall give
            written notice to the Operator that such Draft Project Budget has
            been approved or disapproved by the SPV and the Lender.  If such
            Draft Project Budget shall be disapproved, the Operator shall in
            good faith propose modifications thereto until such Draft Project
            Budget, as so modified, shall be approved.  If the Operator, the
            SPV and the Lender cannot agree on a Draft Project Budget for any
            Contract Year, such disagreement shall be resolved in accordance
            with the procedures set forth in Section 5.2.

                  (iii)  Not later than the first day of any Contract Year,
            the Operator shall submit to the SPV, the Independent Engineer,
            the Lender, the Existing Creditors, the Disbursement Agent and
            the Owner a final project budget (the "Project Budget") which
            shall be the same as the Draft Project Budget in respect of such
            Contract Year that has been approved by the SPV and the Lender,
            with only such changes therein as shall not, without the prior
            written consent of the SPV and the Lender (which consent shall
            not be unreasonably withheld), add or delete any line item set
            forth in such Draft Project Budget or increase or decrease any
            line item amount set forth in such Draft Project Budget by more
            than 2%; provided that, if no Draft Project Budget has been
            approved by the SPV and the Lender by the first day of any
            Contract Year, a Draft Project Budget for such Contract Year that
            is so approved subsequent to such date shall be the Project
            Budget for such Contract Year with no modifications therein that
            are not approved by the SPV and the Lender.

                  (iv)  The Operator shall not make any expenditure in
            respect of Operation and Maintenance Costs for any Contract Year
            except (subject to Section 1.4(c)) pursuant to a Project Budget
            that has been submitted to the SPV and the Lender in accordance
            with the foregoing clause (iii) (unless any such expenditure is
            to be made at a time when a Project Budget for such time has not
            been approved, in which event such expenditure shall be made
            pursuant to the Extended Budget applicable to such time, if any).

                  (v)  No later than 60 days after the end of each Contract
            Year, the Operator shall, in compliance with accepted financial
            practice and Prudent 
<PAGE>                                -4-<PAGE>
            Industry Practice, prepare and submit to the SPV, the Lender and
            the Independent Engineer an item by item reconciliation (rounded
            to the nearest $1,000) of the previous Contract Year's Project
            Budget and the actual Operation and Maintenance Costs for such
            Contract Year, together with an explanation, in reasonable
            detail, of the principal causes of any variances of more than
            $50,000 from the Project Budget.

            (b)  Not later than June 1 of each year, the Operator shall
    prepare and submit to the SPV, the Independent Engineer, the Existing
    Creditors, the Disbursement Agent, the Lender and the Owner

                  (i)  a proposed line item budget (as finally approved as
            provided in this paragraph (b), the "Extended Budget") setting
            forth by category the Operator's projections of the cost of
            operating the Project during the 12 consecutive months ending on
            June 30 of the following year, on a month by month basis, 

                  (ii)  detailed backup information sufficient to permit an
            informed review of such proposed Extended Budget, and 

                  (iii)  the levels of projected lime purchases by OPCO
            during the twelve month period beginning on July 1 of such year,
            based upon:

                         (A)  with respect to the first six months of such
            period, the levels of projected lime purchases provided to the
            SPV by OPCO pursuant to Article III (c) of the OPCO Agreement,
            and

                         (B)  with respect to the final six months of such
                         period the Operator's best estimate of OPCO purchases
                         based upon all of the facts known to the Operator at
                         such time.

Each Extended Budget shall contain a separate line item for the costs of
coal/petroleum coke, electricity, insurance, property taxes, labor,
scheduled recurring capital expenses, and Other Costs based upon the
projected levels of lime purchases provided to the SPV by OPCO pursuant to
Article III(c) of the OPCO Agreement, all as more fully set forth on
Schedule 2 hereto.  Within 45 days after its receipt of a proposed
Extended Budget for any period, the SPV and the Lender shall give written
notice to the Operator that such proposed Extended Budget has been
approved or disapproved by the SPV and the Lender.  If such proposed
Extended Budget shall be disapproved, the Operator shall in good faith
propose modifications thereto until an Extended Budget, as so modified,
shall be approved (at which time copies of such approved Extended Budget
shall be delivered to the SPV, the Independent Engineer, the Existing
Creditors, the Disbursement Agent, the Lender and the Owner).  If the
Operator, the SPV and the Lender cannot agree on an Extended Budget for
any period, such disagreement shall be resolved in accordance with the
procedures set forth in Section 5.2.  The Extended Budget shall only be
used for purposes of determining deposit and disbursement obligations
under Section 2.4 of the Deposit and Disbursement Agreement and for the
purposes set forth in Section 1.4(a)(iv) and Section 1.4(c).
<PAGE>                                -5-<PAGE>
            (c)  The Operator shall make all expenditures of Operation and
    Maintenance Costs, consistent with Prudent Industry Practice and the
    then current Project Budget, in the normal course of business and as
    necessary or advisable for the performance of the Operating Work;
    provided, however, that:

              (i)  subject to clauses (ii) and (iii) below, if such
            expenditures by the Operator in any Contract Year would, when
            taken together with all other such expenditures for such Contract
            Year, exceed any applicable line item amount in the Project
            Budget for such Contract Year (or the relevant Extended Budget,
            if applicable), the Operator shall give the SPV, the Lender and
            the Independent Engineer prompt notice of such fact;

              (ii)  subject to clause (iii) below, the Operator may not,
            without the prior written consent of the SPV and the Lender, make
            any expenditure (A) in any month, if such expenditure together
            with all other similar expenditures in such month would exceed
            the line item amount applicable to such expenditure in the
            Project Budget (or the Extended Budget, if applicable) for such
            month by 10% or more, or (B) in any Contract Year, if such
            expenditure together with all other expenditures made in such
            Contract Year at or prior to such time would exceed by 5% or more
            the total expenditures in the Project Budget (or the Extended
            Budget, if applicable) for such portion of such Contract Year;

              (iii)  the restrictions set forth in clauses (i) and (ii) above
            shall not apply if (A) an Operating Emergency shall have
            occurred; (B) the Operator shall have given the SPV and the
            Independent Engineer an Emergency Notice within 48 hours after
            the occurrence of such Operating Emergency; and (C) such
            expenditures are necessary, consistent with Prudent Industry
            Practice, within such 48-hour period to avoid or alleviate such
            Operating Emergency; no such expenditures shall be made after
            such 48-hour period without the prior written consent of the SPV;
            

              (iv)  the restrictions set forth in clause (ii) above shall not
            apply to the line item amounts for coal/petroleum coke,
            electricity and Other Costs if the number of tons of processed
            lime produced by the Project in any month or in any Contract Year
            is more than the number of tons projected by the Project Budget
            or the Extended Budget, as the case may be, for such period;
            provided, however, that any increase in any such line item
            amount, as set forth in the Project Budget or the Extended
            Budget, as the case may be, shall not exceed a percentage of such
            line item amount equal to the percentage increase in the number
            of tons of lime produced by the Project during such month or
            Contract Year, as the case may be, over the number of tons
            projected to be so produced during such period in the Project
            Budget or the Extended Budget, as the case may be; and

            (v)  the restriction set forth in clause (ii)(A) above shall not
apply to any scheduled recurring capital expenditure.
    
    All such expenditures incurred by the Operator in compliance with the
    terms of this Agreement (including, without limitation, the preceding
    proviso), and all expenditures for 
<PAGE>                                -6-<PAGE>
    material substitutions, replacements or repairs of parts or equipment
    incorporated into the Project with the prior written consent of the
    SPV, shall be binding upon the SPV and shall constitute Operation and
    Maintenance Costs for all purposes hereunder.  Expenditures (that are
    made with the prior written consent of the SPV) in respect of Capital
    Additions or Modifications, or adjustments, alterations or other
    physical changes to the Project, shall not constitute Operation and
    Maintenance Costs for any purpose hereunder unless otherwise agreed to
    in writing by the SPV.  Notwithstanding the foregoing, the scheduled
    recurring capital expenditures referred to on Schedule 2 hereto shall
    constitute Operation and Maintenance Costs.

            (d)  All payments of Operation and Maintenance Costs shall be
    made in accordance with Section 2.2(b)(ii)(A) of the Deposit and
    Disbursement Agreement.  In the event that the Disbursement Agent fails
    to make all or a portion of the disbursement required to be made by it
    pursuant to Section 2.2(b)(ii)(A) of the Deposit and Disbursement
    Agreement, or the amount of such disbursement is insufficient to pay
    all Operation and Maintenance Costs then due and payable and the SPV
    (or any Person on behalf of the SPV, as provided in the Transaction
    Documents) has not paid to the Disbursement Agent or the Operator an
    amount equal to such shortfall, then the Operator shall advance the
    amount of such disbursement or portion thereof (including all amounts
    due to the Owner hereunder) and shall continue to perform the Operating
    Work.  If the Disbursement Agent has not fully repaid the amounts owing
    to the Operator under this Section 1.4(d) with respect to an advance
    under this Section 1.4(d) by the close of business on the first
    Business Day after the 60th day following the date on which the advance
    was made, the Operator shall not have any further obligation to advance
    additional funds pursuant to this Section 1.4(d) or to continue to
    perform the Operating Work and the SPV shall remain obligated to repay
    such advances; provided, however, that the Operator shall not institute
    legal proceedings to recover such advances from the SPV, except to the
    extent provided in Section 5.10, unless and until the Secured
    Obligations have been paid in full.  Except as provided in this Section
    1.4(d), the Operator shall not be required to advance funds to the SPV
    or the Owner in order to comply with its obligations under this
    Agreement.

    1.5  Outages.  At the same time the Project Budget is delivered
pursuant to Section 1.4(a), the Operator shall deliver to the SPV and the
Independent Engineer a schedule (the "Outage Schedule") of all planned
outages (including those for inspection and ordinary maintenance of the
Project) for such Contract Year.  The Operator shall, to the extent
practicable, adhere to such Outage Schedule during such Contract Year. 
The scheduling and carrying out of such outages shall be (i) to the extent
consistent with clauses (iii) and (iv) below, made on a nondiscriminatory
basis with respect to the Black River Facility, (ii) to the extent
consistent with clauses (iii) and (iv) below, coordinated with the
Operator's other plant maintenance outages in accordance with Prudent
Industry Practice, (iii) coordinated with OPCO and any other purchasers of
processed lime from the SPV to minimize any interruption in the supply of
processed lime that is to be delivered to OPCO pursuant to the OPCO
Agreement, to the purchasers under Economically Similar Contracts, and to
the purchasers under the other lime supply contracts to which the SPV may,
from time to time, be a party (with the consent of the Existing Creditors)
and (iv) made in accordance with Prudent Industry Practice to minimize
both interruptions to the operation of the Project and the Black River
Facility and any loss of profits as a result of the timing of such
interruptions.  In the event of an Operating Emergency or any other
emergency 
<PAGE>                                -7-<PAGE>
outage, forced outage, or reduction in production below a Total Net
Capability of at least 650,000 tons per annum for any reason, the Operator
shall schedule and perform all required repairs and replacements, and
restore production to a Total Net Capability of at least 650,000 tons per
annum, in an expeditious manner in accordance with Prudent Industry
Practice and the other requirements of this Agreement.

    1.6  Books and Records; Reports.

      (a) The Operator shall keep all necessary books of record, books of
    account and memoranda of all transactions referred to in this Article 1
    involving the Project, including, without limitation, of the services
    provided and the funds received and expended by the Operator in the
    course of performing the Operating Work.  Such books of record, books
    of account and memoranda shall be kept by the Operator in such manner
    as to conform to GAAP and to all Applicable Laws.  The Operator shall,
    if it owns and/or is operating or is otherwise involved with the Black
    River Facility, keep separate books of record, books of account and
    memoranda of transactions for each of the Project and the Black River
    Facility.

      (b)  The Operator shall prepare and, to the extent permitted by
    Applicable Law, file in a timely fashion; or, if the SPV shall be
    required to so file, the Operator shall prepare and deliver to the SPV
    within a reasonable time prior to the date for filing, all reports with
    respect to the Project or the Black River Facility, or the condition or
    operation thereof, that shall be required to be filed with any
    Governmental Authority.

      (c)  The Operator shall, not later than 20 days after the end of each
    calendar month, prepare and deliver a report to the SPV (with copies to
    the Lender and the Independent Engineer) setting forth the monthly and
    annual cumulative output, the production levels, the variance from
    forecast, and a description of outages and operating hours for the
    Project.  In addition, the Operator shall prepare and deliver such
    other reports as the SPV or the Lender may reasonably request.

      (d)  The Operator shall, not later than 60 days after the end of each
    Project Quarter, prepare and deliver a report to the SPV (with copies
    to the Lender and the Independent Engineer) summarizing the operating
    and maintenance costs and revenues for such Project Quarter, which
    report shall provide a breakdown of Operation and Maintenance Costs.

    1.7  Inspection Rights.  Upon reasonable notice to the Operator, during
normal business hours, the SPV, the Lender, the Existing Creditors and
their respective representatives shall, subject to customary
confidentiality and safety procedures, have (i) access to the Project and
the Black River Facility for purposes of the inspection thereof and (ii)
the right to inspect the books of record, books of account and memoranda
of the Operator relating to the Project and the Black River Facility, to
make copies and extracts therefrom (other than copies of and extracts from
proprietary data and information) and to discuss with the executive
officers of the Operator the finances and accounts relating to the Project
and the Black River Facility and, with respect to the operations of the
Project, the senior technical employees of the Operator.  The Operator
will cooperate with such Persons in connection with any such inspection or
discussion.  Such inspection and copying shall be solely at the expense of
the Person requesting the same, unless 
<PAGE>                                -8-<PAGE>
done in connection with the removal of the Operator (in which case such
inspection shall be at the sole expense of the Operator).

    1.8  Annual Audit.  The books, records and accounts of Operation and
Maintenance Costs maintained by the Operator pursuant to Section 1.6 shall
be subject to an audit as of the end of and for each Contract Year by KPMG
Peat Marwick or another firm of nationally recognized independent public
accountants selected by the Operator.  The SPV, the Lender and the
Existing Creditors, and any of their respective representatives, shall be
permitted to check and review all accounting records relating to the
operation of the Project and the Black River Facility and to observe the
procedures followed by the Operator's accountants.  The report of such
firm of independent public accountants for such Contract Year shall be
submitted to the Operator, with a copy to the SPV, each Existing Creditor
and the Lender within 90 days after the end of such Contract Year.  The
cost of such annual audit shall constitute an Operation and Maintenance
Cost.

    1.9  Uncontrollable Forces.  The Operator shall not be considered to be
in default in the performance of any of its obligations under this Article
1, other than obligations to pay money, if (a) such failure of performance
shall be due to Uncontrollable Forces and (b) the obligations of the
"Producer" are similarly excused under the OPCO Agreement as well as under
any Economically Similar Contract and each and every other contract to
supply processed lime to which the SPV is then a party; provided, that the
Operator agrees that if such Uncontrollable Forces arise as a result of
the unavailability of the Operator's personnel, the SPV may hire such
personnel as may be necessary to permit operation and maintenance of the
Project to the extent consistent with applicable law.  If the Operator is
rendered unable to fulfill any obligation by reason of Uncontrollable
Forces, it shall give prompt notice of such fact to the SPV (with copies
to the Lender and the Independent Engineer) and shall exercise reasonable
diligence to remove said inability with all reasonable dispatch.  Nothing
contained herein shall be construed to require a party to settle any
strike or labor dispute in which it may be involved.

    1.10  Removal of Operator.

      (a) So long as any of the Secured Obligations shall remain
    outstanding, Lime shall be subject to removal as Operator by the Lender
    or the Collateral Agent if:

              (i)  45 days' prior written notice of such removal has been
            provided to Lime and the Existing Creditors' Agent by the Lender
            or the Collateral Agent, and

              (ii)  (A)  either

                         (1) Lime, as Operator, shall have failed to perform or
                         observe any covenants or agreements to be performed or
                         observed by it, as Operator, under Section 1.3 hereof;

                         (2) Lime, as Owner, shall have failed to perform or
                         observe any covenant or agreement to be performed or
                         observed by it under Section 2.1, Section 2.2, Section
                         2.5, Section 3.1(b), Section 3.1(c) or Section 3.2, and
                         such failure shall have continued, after 
<PAGE>                                -9-<PAGE>
                         Lime has been given a notice specifying such failure
                         and requiring such failure to be remedied, for a period
                         of 10 days;

                           (3) an Event of Default under the Note Purchase
                         Agreement (as in effect on the Initial Funding Date)
                         shall exist; or

                           (4)(I) Lime shall have failed to perform or observe
                         any other covenant or agreement to be performed or
                         observed by it, as either Owner or Operator, under this
                         Agreement or in any capacity under any other
                         Transaction Document to which it is a party, and the
                         failure referred to in this subclause (4)(I) has had,
                         or could reasonably be expected to have, a material
                         adverse effect on the Project, or (II) such failure
                         shall have continued, after Lime has been given a
                         notice specifying such failure and requiring it to be
                         remedied, for a period of 30 days and

                     (B)  any applicable period for the cure of any failure
            to perform or observe, or any applicable period for the cure of
            any Event of Default referred to in the foregoing clause (A)
            shall have expired.

      (b)  So long as any of the Existing Creditor Indebtedness shall
    remain outstanding, the Existing Creditors shall have the right, but
    not the obligation, to replace Lime as the operator of the Black River
    Facility if the Existing Creditors or the Existing Creditors' Agent
    (acting on behalf of the Existing Creditors) shall have conveyed,
    assigned or sold the same to an Acceptable Transferee.  If the Existing
    Creditors have foreclosed on the Black River Facility and such
    Acceptable Transferee intends to operate and maintain the Black River
    Facility itself, the Existing Creditors may request that the Lender or
    the Collateral Agent remove Lime as the Operator and appoint such
    Acceptable Transferee in lieu thereof, and, if the Independent Engineer
    has confirmed to the Lender in writing that such Acceptable Transferee
    has the experience, personnel and expertise necessary to operate the
    Project, the Lender or the Collateral Agent shall effect such
    replacement.

      (c)  If at any time Lime has been replaced as Operator by the Lender
    or the Collateral Agent, the Existing Creditors shall have the right,
    but not the obligation, to replace Lime as the operator of the Black
    River Facility.

      (d)  If Lime has been replaced as Operator, any Replacement Operator
    (other than Lime if Lime shall have been reinstated as Operator) shall
    be subject to removal at any time, with or without cause, upon 3
    Business Days' prior written notice (i) from the Lender or the
    Collateral Agent or (ii) by the Existing Creditors pursuant to Section
    1.10(b).

      (e)  In the event of the removal of any Operator, such removed
    Operator shall 

              (i)  cooperate and use its reasonable efforts to transfer (to
            the extent transferable) any Governmental Approvals that it may
            have which are required or useful in the operation of the Project
            to any Replacement Operator or the SPV, and 
<PAGE>                                -10-<PAGE>
              (ii)  immediately thereafter deliver to any Replacement
            Operator or to the SPV all books and records, equipment,
            operating manuals, plans and specifications, tools, spare parts
            and other materials used by such removed Operator in connection
            with the Operating Work;

    provided, however, that such removed Operator shall not be obliged to
    transfer any such Governmental Approvals or equipment, operating
    manuals, plans and specifications, tools, spare parts or other
    materials if (A) such items are required or used by Lime in connection
    with the operation of the Black River Facility, and (B) the cost of
    obtaining same was not paid with funds provided by the SPV.

With regard to Governmental Approvals for which the cost was not paid by
SPV, but which are required or useful in the operation of the Project by
any Replacement Operator or the SPV, such removed Operator:

                           (A)  shall not interfere with or lodge objection to
                         any efforts by Replacement Operator to obtain its own
                         Governmental Approvals for activities conducted on the
                         Site,

                           (B)  upon request, shall consent to and cooperate in
                         the deletion, division and/or transfer to Replacement
                         Operator of those portions of the Governmental
                         Approvals governing those portions of the Site and
                         activities that cannot or will not, by virtue of
                         removal of Operator, be used by it in connection with
                         the operation of the Black River Facility, and

                           (C)  with regard to Governmental Approvals for which
            Replacement Operator cannot obtain new or transferred
            Governmental Approvals without delay or unreasonable interference
            with the continued operation of the Project, shall consent to and
            not interfere with Replacement Operator's use of the then-
            existing Governmental Approvals for the activities conducted on
            the Site.

      (f)  Any Person that shall become the Operator or a Replacement
    Operator hereunder shall have all of the rights, duties and obligations
    of the Operator as specified herein.

    1.11  Appointment of a New Operator.  

      (a)  In connection with any removal of the Operator pursuant to
    Section 1.10(a), the Lender shall, subject to (1) approval by the
    Independent Engineer, (2) the provisions of Section 1.10(a) and (b) and
    (3) the following provisions of this Section 1.11(a), appoint a new
    Operator (the "Replacement Operator") to assume the duties and
    obligations of the Operator under this Agreement.  Upon such
    appointment, all references to the Operator herein shall be deemed to
    be references to the Replacement Operator.  During the 45-day period
    referred to in Section 1.10(a)(i), the Lender and the Existing
    Creditors shall attempt to reach mutual agreement as to a Replacement
    Operator to be appointed hereunder.  If the Lender and the Existing
    Creditors agree to an appropriate Replacement Operator 
<PAGE>                                -11-<PAGE>
    during such 45-day period, then the Lender shall appoint such Person as
    Replacement Operator.  If the Lender and the Existing Creditors are
    unable to agree as to an appropriate Replacement Operator during such
    45-day period, then the Lender may, subject to Section 1.10(b), appoint
    a Replacement Operator without the Existing Creditors' consent;

      (b)  Any Replacement Operator shall have an obligation to negotiate
    in good faith with the Existing Creditors to enter into an operation
    and maintenance agreement with respect to the Black River Facility, but
    neither such negotiation nor the execution of any such agreement shall
    be a condition to any Replacement Operator acting hereunder.

    1.12  Indemnification.

      (a) The Operator shall defend, indemnify and hold harmless each
    Indemnitee and each Existing Creditor from and against any and all
    Expenses incurred by or asserted against any Indemnitee or Existing
    Creditor as a result of, arising out of, related to or in connection
    with the Operator's, or any of its subcontractors', performance of the
    Operator's obligations hereunder, including, without limitation, claims

              (i) for injury to or death of persons and loss of or damage to
            property (including, without limitation, the Project);

              (ii) on account of any violation of any Applicable Law to be
            complied with by the Operator or any contractor or subcontractor
            hereunder; or

              (iii) in respect of any taxes imposed on or attributable to the
            income, property or activities of the Operator or demands by or
            liens of suppliers or subcontractors for nonpayment of amounts
            due as a result of furnishing work or materials to the Operator
            in connection with the Project;

    provided, however, that the Operator shall not defend, indemnify or
    hold harmless any Indemnitee or Existing Creditor from and against, and
    no Indemnitee or Existing Creditor shall be exculpated from, any
    Expense to the extent (A) caused by or arising from the gross
    negligence or willful misconduct of such Indemnitee or Existing
    Creditor or (B)(1) consisting of any Expense provided for in any
    Project Budget or Extended Budget, or otherwise expressly provided for
    in this Agreement, including Schedule 2 hereto, or (2) consisting of
    any principal of, or interest or Make-Whole Amount in respect of, the
    Notes.

      (b)  The procedures for such indemnification shall be governed by
    Section 17.2 of the Note Purchase Agreement, which Section is
    incorporated herein, mutatis mutandis, as if fully set forth herein.

      (c)  Notwithstanding any other provision of this Agreement, the
    Operator's obligations under this Section 1.12 are intended to, and
    shall, survive termination of this Agreement.
<PAGE>                                -12-<PAGE>
      (d)  Notwithstanding anything to the contrary in this Section 1.12,
    the Operator shall not be liable to indemnify any Indemnitee or
    Existing Creditor for any Expenses representing any indirect, special
    or consequential damages.

ARTICLE 2.               OWNER'S SUPPLY OBLIGATIONS

    2.1  Limestone Supply.  Subject to the requirements of this Article 2,
the Owner hereby agrees to supply and sell to the Operator, for the
account of the SPV, such quantities of unprocessed limestone as shall be
necessary or advisable for the SPV to meet the requirements of the SPV for
the continuous operation of the Project at a Total Net Capability of at
least 650,000 tons per annum.  Such unprocessed limestone supplied by the
Owner hereunder shall be suitable to meet the technical and other
specifications for processed lime set forth in the OPCO Agreement and all
such other processed lime supply contracts the SPV may, from time to time,
enter into in compliance with the Transaction Documents.  The Owner shall
cause such unprocessed limestone to be tested in accordance with
reasonable and customary tests established by the Independent Engineer, in
accordance with Prudent Industry Practice, and shall maintain records of
the results of all such tests.  Title to the unprocessed limestone sold to
the SPV pursuant to this Section 2.1 shall pass to the SPV at such time as
the unprocessed limestone is placed in the Project Kilns.  Risk of loss
shall follow title.

    2.2  Additional Supply Obligations of the Owner.

      (a)  The Owner further agrees to supply and sell to the Operator, for
    the account of the SPV, all supplies, goods, materials and other
    products, items and services set forth in Schedule 3 and such other
    goods and services as may be required by the Operator in connection
    with the Operating Work (collectively, together with the unprocessed
    limestone, the "Supplies").  The cost of Supplies provided by the Owner
    shall be determined in accordance with Schedule 2 hereto.  Each of the
    parties hereto acknowledges and agrees that the Owner, in performing
    its duties hereunder, is acting as an independent contractor.

      (b)  The Owner may enter into such agreements or subcontracts (and
    modifications thereof) and take such other action as the Owner, in
    compliance with Prudent Industry Practice, deems necessary or
    appropriate, in its judgment, or as may be required by Applicable Law,
    to comply with the provisions of this Agreement.  Any such agreement or
    subcontract (or modification thereof), except for any collective
    bargaining agreement, that provides for the payment of more than
    $100,000 by any party thereto, or shall refer to the SPV, the Lender or
    the Collateral Agent, shall expressly provide that it does not impose
    on the SPV or any other party to the Transaction Documents (other than
    the Owner) any obligation, liability or duty to a contractor or
    subcontractor or create any contractual relationship between a
    contractor or subcontractor and the SPV or any other party to the
    Transaction Documents (other than the Owner).

      (c)  If the Owner shall at any time breach its obligation to supply
    unprocessed limestone or any other Supplies required by this Article 2
    (whether by anticipatory breach or otherwise), the SPV may take
    commercially reasonable steps to obtain as promptly as possible a
    suitable replacement for such limestone or other supplies; and the
    Owner shall be liable to the SPV for the excess of the price so paid by
    the SPV for such limestone 
<PAGE>                                -13-<PAGE>
    or other Supplies (including the cost of labor attributable to mining
    and the cost of such Supplies) over the price which SPV would have been
    liable to pay therefor hereunder had the Owner not breached its supply
    obligation, plus any expenses incidental to obtaining such suitable
    replacement or other supplies.

      (d)  Without limiting the generality of the foregoing, the Owner
    shall obtain and maintain at all times for the benefit of the SPV or
    its designee and the Project all material Governmental Approvals
    relating to (i) the ownership, construction, operation and maintenance
    of the Project in accordance with Applicable Law, and (ii) which can
    not be, or are not, issued in the name of the SPV.  The Owner shall
    from time to time take any action as shall be necessary or desirable to
    have issued in the name of the SPV any such material Governmental
    Approval that must, by its nature, be issued in the name of the SPV in
    accordance with Applicable Law.

      (e)  If OPCO becomes entitled to receive deliveries of processed lime
    under the OPCO Agreement prior to the Substantial Completion Date,
    promptly upon notice thereof from the SPV or the Operator, Lime shall
    cause such deliveries to be made to OPCO on behalf of the SPV, from
    lime processed at the Black River Processing Complex or the Maysville
    Processing Complex, in strict compliance with the OPCO Agreement.  In
    no event shall Lime be entitled to receive any amounts payable by OPCO
    to the SPV under the OPCO Agreement in respect of such lime deliveries
    except as provided in Section 3.4 hereof.

    2.3  Books of Record; Reports.  The Owner shall keep all necessary
books of record, books of account and memoranda of all transactions
referred to in this Article 2 and in Article 3, including, without
limitation, records as to the Supplies provided and the funds received and
expended by the Owner in the performance of its obligations hereunder. 
Such books of record, books of account and memoranda shall be kept by the
Owner in such manner as to conform to GAAP and all Applicable Laws.  The
Owner shall keep separate books of record, books of account and memoranda
of transactions for each of the Project and the Black River Facility.

    2.4  Access to Books and Records.  Upon reasonable notice to the Owner,
during normal business hours, the SPV, the Existing Creditors, the Lender
and their respective representatives shall, subject to customary
confidentiality and safety procedures, have (i) access to the Project and

the right to inspect the books of record, books of account and memoranda
of the Owner relating to the Project or the Black River Facility, to make
copies and extracts therefrom (other than copies of and extracts from
proprietary data and information) and to discuss same with the executive
officers of the Owner.  The Owner will cooperate with such Persons in
connection with any such inspection or discussion.  Such inspection and
copying shall be solely at the risk and expense of the Person requesting
the same.

    2.5  Payment of Supply Costs.  The cost of Supplies under Sections 2.1
and 2.2 hereof shall be determined in accordance with Schedule 2 and shall
constitute Operation and Maintenance Costs.  All payments of supply costs
shall be made by the Operator pursuant to Article 1 hereof.  In the event
that the Operator fails to make all or a portion of the payments to the
Owner required to be made by the Operator hereunder, or the amount of such
disbursement is insufficient to pay all supply costs then due and payable,
then the Owner shall advance the 
<PAGE>                                -14-<PAGE>
amount of such disbursement or portion thereof and shall continue to
perform its obligations under this Article 2.  If the Operator has not
fully repaid the amounts owing to the Owner under this Section 2.5 with
respect to an advance under this Section 2.5 by the close of business on
the first Business Day after the 60th day following the date on which the
advance was made, the Owner shall not have any further obligation to
advance additional funds pursuant to this Section 2.5 or to continue to
perform its obligations under this Article 2, and the Operator shall
remain obligated to repay such advances.  Except as provided in this
Section 2.5, the Owner shall not be required to advance its own funds to
the Operator in order to comply with its obligations under this Agreement.

    2.6  Annual Audit.  The books, records and accounts of supply costs
maintained by the Owner pursuant to Section 2.3 shall be subject to an
audit as of the end of and for each Contract Year by KPMG Peat Marwick or
another firm of nationally recognized independent public accountants
selected by the Operator.  The SPV, the Lender and the Existing Creditors,
and any of their respective representatives, shall be permitted to check
and review all accounting records relating to the Project or the Black
River Facility and to observe the procedures followed by the Owner's
accountants.  The report of such firm of independent public accountants
shall be submitted to the Owner, with a copy to the Operator, the SPV,
each Existing Creditor and the Lender within 90 days after the end of such
Contract Year.  The cost of such annual audits shall constitute Operation
and Maintenance Costs.

    2.7  Uncontrollable Forces.  The Owner shall not be considered to be in
default in the performance of any of its obligations under this Article 2,
other than obligations to pay money, if (a) such failure of performance
shall be due to Uncontrollable Forces and (b) the obligations of the
"Producer" are similarly excused under the OPCO Agreement as well as under
each and every Economically Similar Contract.  If the Owner is rendered
unable to perform any obligation by reason of Uncontrollable Forces, it
shall, upon acquiring knowledge of the same, give prompt notice of such
fact to the other parties hereto and shall exercise reasonable diligence
to remove said inability with all reasonable dispatch.  Lime covenants
that, to the extent that SPV is unable to produce processed lime at the
Project required to service the OPCO Agreement as the result of an
Operating Emergency or Uncontrollable Forces (or any combination of the
foregoing), Lime shall comply with the OPCO Agreement (including, without
limitation, Articles 1(a) and (b) thereof).

    2.8  Most Favored Nation.  Neither Lime, nor any party that would be a
successor to or assign of Lime for purposes of the OPCO Agreement, or that
would otherwise be bound by the OPCO Agreement, shall, without the consent
of the Holders, take any action which would require an adjustment to the
purchase price to OPCO under the OPCO Agreement in accordance with Article
XXII of the OPCO Agreement

    under this Agreement and as contemplated by the Easement Agreement.

            (ii)  The Operator and the SPV covenant that the Owner shall, on

this Agreement and as contemplated by the Easement Agreement.

            (iii)  The Operator shall operate the Project and the Black River
    Processing Complex for the benefit of the Owner and the SPV in
    accordance with this Agreement and the Easement Agreement.  Each of the
    Operator and the Owner covenants that, during the term of this
    Agreement, it shall operate, maintain, rebuild and repair the Project
    in compliance with the requirements imposed upon the SPV by Section 9
    of the Note Purchase Agreement to the extent applicable to such
    operation, maintenance, rebuilding or repair (other than Sections 9.4,

    applicable (other than such specified sections) is incorporated herein
    by reference, mutatis mutandis.

              (i)  make a payment (each, a "Tolling Payment") to the
            Disbursement Agent, in an amount equal to 50% of the result of
            (A) the Scheduled Variable Cost Savings Per Ton multiplied by (y)
            the number of Non-OPCO Tons produced by the Project during such
            month; and

              (ii)  make a payment to the Disbursement Agent in an amount
            equal to the result of (A) the Operation and Maintenance Costs of
            the Project during such month (other than Operation and
            Maintenance Costs paid with the written consent of the SPV that
            relate to Capital Additions or Modifications, adjustments,
            alterations, and other physical changes to the Project and
            material substitutions, replacements or repairs of parts or
            equipment incorporated into the Project) multiplied by (B) a

            Agent in an amount equal to one half of

                           (A) the product obtained by multiplying (1) 1.3 by
                         (2) the amount of Capacity Payment Debt Service payable
                         with respect to such Project Quarter and the next
                         succeeding Project Quarter, minus

                           (B) the Deemed Cash Flow attributable to the sum of
                         (1) the actual number of tons of processed lime
                         purchased by OPCO pursuant to the OPCO Agreement or
                         purchased pursuant to Economically Similar Contracts
                         during such Project Quarter plus (2) the number of tons
                         of processed lime projected to be purchased by OPCO
                         during such next succeeding Project Quarter, as set
                         forth in the letter delivered by OPCO pursuant to
                         Article III(c) of the OPCO Agreement (provided, that in
                         no event shall such sum be less than 150,000), minus

                           (C) the sum of the Tolling Payments made by the Owner
                         in respect of such Project Quarter and the immediately
                         preceding Project Quarter;

            provided, however, that the Capacity Payment shall not be less
            than zero.

              (ii)  Notwithstanding Section 3.2(b)(i), the aggregate amount
            of Capacity Payments payable by Lime with respect to any Contract
            Year shall not exceed the lesser of (A) the sum of the payments
            due with respect to Project Quarters during such Contract Year
            pursuant to Section 3.2(b)(i); and (B) the Maximum Capacity
            Payment with respect to such Contract Year.

              (iii)  The Maximum Capacity Payment with respect to any
            Contract Year shall be an amount equal to (A) the product

            minus (B) the Deemed Cash Flow attributable to 300,000 tons of 
<PAGE>                                -17-<PAGE>
            processed lime; provided, however, that, so long as Lime is the
            Owner and owns and operates the Maysville Processing Complex, in
            the event that an aggregate of less than 190,000 tons of Non-OPCO
            Lime under Compatible Lime Supply Agreements are produced at the
            Project, the Black River Processing Complex and the Maysville
            Processing Complex during a Contract Year, the Maximum Capacity
            Payment for such Contract Year shall be reduced by an amount
            equal to the product of (x) the Scheduled Variable Cost Savings
            Per Ton and (y) the excess of (I) 190,000 over (II) the aggregate
            number of tons (but not less than 60,000 in any event) of
            Non-OPCO Lime under Compatible Lime Supply Agreements produced at
            the Project, the Black River Processing Complex and the Maysville
            Processing Complex during such Contract Year; and provided
            further, that, so long as Lime is the Owner and owns and operates
            the Maysville Processing Complex, in the event that an aggregate
            of less than 60,000 tons of Non-OPCO Lime under Compatible Lime
            Supply Agreements are produced at the Project, the Black River
            Processing Complex and the Maysville Processing Complex during a
            Contract Year, the Maximum Capacity Payment for such Contract
            Year shall be further reduced by an amount equal to the product
            of (xx) the Project Profit Margin Per Ton and (yy) the excess of
            (I) 60,000 over (II) the aggregate number of tons of Non-OPCO
            Lime under Compatible Lime Supply Agreements produced at the
            Project, the Black River Processing Complex and the Maysville
            Processing Complex during such Contract Year.

              (iv)  Deemed Cash Flow for various levels of lime production
            shall be as set forth on Schedule 5 hereto.

              (v)  The Capacity Payment payable with respect to any Project
            Quarter shall be adjusted to reflect the limitations set forth in
            Section 3.2(b)(ii) and Section 3.2(b)(iii); provided, however,
            that if the Capacity Payments paid at any time during a Contract
            Year equal the Maximum Capacity Payment with respect to such
            Contract Year, no further Capacity Payments shall be payable with
            respect to such Contract Year.

      (c)  Each payment made by the Owner or Lime under this Article 3
    shall be accompanied by an Officer's Certificate of the Owner or Lime,
    as the case may be, setting forth in detail the calculations of such
    payment.  Upon the request of the Lender or the SPV, the Owner or Lime,
    as the case may be, shall provide such additional information and
    details as such Person may reasonably request concerning the
    calculation of such payment.

      (d)  If OPCO has claimed a credit under Article 3(e) and Article 3(f)
    of the OPCO Agreement with respect to any processed lime sold to a
    purchaser other than OPCO, Lime shall pay to the SPV, promptly upon
    receipt thereof, all revenues arising from such sale.  If such
    processed lime was processed at the Black River Processing Complex or
    the Maysville Processing Complex, the SPV will make the payment
    provided for in Section 3.4 (ii) for the cost of production thereof,
    and such cost of production shall constitute Operation and Maintenance
    Costs for purposes of the Deposit and Disbursement Agreement.  
<PAGE>                                -18-<PAGE>
    3.3  Uncontrollable Forces.  Neither the Owner nor the SPV shall be
considered to be in default in the performance of any of its obligations
under this Article 3, other than obligations to pay money, if such failure
of performance shall be due to Uncontrollable Forces; provided that if
such Uncontrollable Forces arise as a result of the unavailability of the
Owner's personnel, the SPV may hire such personnel, in accordance with
Applicable Law, as may be necessary to permit operation and maintenance of
the Project and the Black River Common Facilities.  If either such party
is rendered unable to fulfill any obligation by reason of Uncontrollable
Forces, it shall, upon acquiring knowledge of the same, give prompt notice
of such fact to the other parties hereto and shall exercise reasonable
diligence to remove said inability with all reasonable dispatch.

    3.4  Maysville and Black River Production.  If the SPV is paid the
gross revenues arising from the sale of any quantity of processed lime
that was processed at the Black River Processing Complex or the Maysville
Processing Complex, including, without limitation, (i) lime sold to OPCO
pursuant to Section 2.2(e) or Section 2.7 hereof and (ii) processed lime
in respect of which OPCO has claimed a credit under Article 3(e) and
Article 3(f) of the OPCO Agreement, the SPV will, on the first and
fifteenth days of each month, pay to Lime for each ton of such processed
lime for which SPV has received such revenues, an amount equal to the
fixed and variable costs of producing such ton at the facility where such
production occurred.

    3.5  Books and Records; Access.  Lime shall keep all necessary books of
record, books of account and memoranda with respect to its Capacity
Payment obligation hereunder.  Upon reasonable notice to Lime, during
normal business hours, the SPV, the Existing Creditors, the Lender and
their respective representatives shall, subject to customary
confidentiality and safety procedures, have the right to inspect such
books of record, books of account and memoranda, to make copies and
extracts therefrom (other than copies of and extracts from proprietary
data and information) and to discuss the same with Lime's executive
officers.  Lime will cooperate with such Persons in connection with any
such inspection or discussion.  Such inspection and copying shall be
solely at the risk and expense of the Person requesting the same.

respective successors and permitted assigns.

  (b)  The parties hereto hereby consent to assignment of this Agreement
in whole or in part by the SPV to the Collateral Agent as security for the

<PAGE>                                -22-<PAGE>
and the Existing Creditors' Agent on behalf of the Existing Creditors in
connection with, or following, an exercise of remedies with respect to
such security).  Neither the SPV nor Lime shall assign this Agreement
except as contemplated by the preceding sentence.

  (c)  Except in connection with an exercise of remedies by the Existing
Creditors, none of the Operator, the Owner or Lime, may assign any of its
rights or obligations under this Agreement to any other Person without the
prior written consent of the SPV.  The Owner hereby covenants that it
shall not sell, assign, transfer or convey, or permit any such sale,
assignment, transfer or conveyance of, its right, title and interest in
and to the Black River Facility to any Person, unless such Person: (A)
acquires in such transaction the entire Black River Facility (including
the limestone mines); (B) has a tangible net worth of at least $50
million; (C) assumes all of the Owner's rights and obligations under
Article 2, Article 3 and Article 5 hereof (other than Section 3.2(b) and
Section 3.2(c), it being understood that the Owner, in such capacity, does
not have any obligation under Section 3.2(b) or with respect to delivery
of the Officer's Certificate to be delivered by Lime pursuant to Section
3.2(c)) pursuant to an instrument satisfactory in form and substance to
the SPV; (D) provides a favorable opinion of counsel (which counsel and
opinion shall be satisfactory to the SPV in all respects) as to the due
authorization, execution and delivery by such Person of such instrument
and as to the enforceability against such Person of this Agreement and
such instrument and as to such other matters as the SPV may reasonably
request; and (E) has the experience, personnel and expertise necessary to
perform as Owner hereunder in the written opinion of the Independent
Engineer (a Person meeting the requirements of clauses (A) through (E)
above shall be referred to herein as an "Acceptable Transferee").

  (d)  Without limiting any of the requirements contained herein, in the
event of a transfer of the Black River Facility to an Acceptable
Transferee, Lime shall cooperate and use its best efforts to transfer (to
the extent transferable without rendering void or voidable) any
Governmental Approvals that it may hold which are necessary or desirable
for the operation of the Black River Facility or the Project to the
successor Owner, and Lime shall promptly deliver to such successor Owner
all books, records, equipment, operating manuals, plans and
specifications, tools, spare parts and all other materials used by Lime in
its capacity as Operator or Owner hereunder, as the case may be.

    5.7  Amendments.  Neither this Agreement nor any of the terms hereof
may be terminated, amended, supplemented, waived or modified orally, but
only by an instrument in writing signed by the party against which the
enforcement of the termination, amendment, supplement, waiver or
modification is sought; provided, however, that it is understood and
agreed that the Operator and the SPV may amend Article 1 and the Schedules
hereto corresponding to such Article without the prior consent of the
Owner, and the Owner and the SPV may amend Articles 2 and 3 and the
Schedules hereto corresponding to such Articles without the prior consent
of the Operator; provided, further, that any such action shall be subject
to the provisions of Section 9.1 of the Intercreditor Agreement.

    5.8  Consultations.  Notwithstanding any other provision of this
Agreement, the Operator and the Owner will, upon reasonable prior notice,
consult with the SPV and its representatives and designees to review any
matter pertaining to their respective obligations hereunder.

    5.9  Counterparts.  This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

    5.10  Set-off.  Each of the SPV, the Owner and the Operator shall have
the right to set off any payments owing by it to either of the other two
such Persons hereunder against payments owing by the Person against which
such right of set-off is exercised.

    5.11  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED

of this Agreement.  The Operator and the Owner shall use their best
efforts, and the SPV shall cooperate therewith, to obtain as quickly as
possible all Governmental Approvals and vendor approvals required to be
obtained by any Person for the transactions contemplated hereby.  The SPV,
the Owner and the Operator shall discharge all their respective
obligations under this Agreement in good faith and in accordance with

Governmental Approvals but shall not be required to expend any funds or
incur any liabilities in connection therewith.

    The SPV shall permit Lime, the Owner and the Operator (i) to make
application, in the SPV's name, for any Governmental Approval necessary
for the operation or maintenance of the Black River Facility and (ii) to
utilize (to the extent permitted by Applicable Law) any Governmental
Approval necessary for such operation or maintenance, and the SPV shall
render reasonable cooperation to Lime, the Owner or the Operator, as the
case may be, in connection therewith, provided that

  (a)  such Governmental Approval can only be issued in the name of the
SPV,

  (b)  all costs and expenses related to such application or utilization
are paid by Lime, the Owner or the Operator, and

  (c)  neither Lime, the Owner nor the Operator has taken any action, or
failed to take any action, which action or failure to act prohibits
issuance of such Governmental Approval in the name of Lime, the Owner or
the Operator, as the case may be.

    5.13  Severability.  Any provision of this Agreement that may be
determined by competent authority to be prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

                                             SCHEDULE 1

                                             OPERATING WORK


    I.  Standard of Care.  The Operator shall perform all of its duties and
obligations under this Agreement in accordance with the standards mandated
under the OPCO Agreement (and each other lime supply or processing
agreement to which the SPV or the Owner may, from time to time, be a
party), in a good, workmanlike and commercially reasonable manner and in
accordance with Prudent Industry Practice.  The Operator shall exercise
such care and shall act diligently as a prudent business entity engaged in
the business of managing and operating a limestone processing facility
comparable to the Project owned by it (or its Affiliates) would exercise
for the advancement and protection of its own economic interests.

    II.  Insurance; Compliance with Insurance Policies, Governmental
Requirements, etc.  The Operator shall procure and maintain all insurance
required to be maintained by the SPV under the Transaction Documents, and
also shall be responsible for making and administering all claims on
behalf of the SPV under insurance policies covering the SPV or the Project
during the term of this Agreement.  The Operator shall comply in all
material respects with, and cause the Project and all Operator personnel
to comply in all material respects with, all applicable standards required
by Prudent Industry Practice, all insurance policies in effect from time
to time with respect to the Project, all manufacturer's recommended
guidelines, all Applicable Laws, all applicable Governmental Approvals and
the Transaction Documents.  Without limiting the generality of the
foregoing, the Operator shall obtain and maintain at all times for the
benefit of the SPV or its designee and the Project all material
Governmental Approvals, and which can not be, or are not, issued in the
name of the SPV.  The Operator shall from time to time take such action as
shall be necessary to have issued in the name of the SPV any such material
Governmental Approval that must, by its nature, be issued in the name of
the SPV in accordance with Applicable Law.

    III.  Personnel.  The Operator shall at all times employ, or cause to
be employed, qualified personnel, properly trained to perform the
Operating Work, and shall pay all wages and benefits required by
Applicable Law or contract.  The Operator shall be responsible for all
matters relating to labor relations, working conditions, training,
employee benefits, safety programs and related matters pertaining to its
employees.  

    IV  Warranties and Guarantees.  The Operator shall use reasonable
efforts to obtain warranties for the SPV for parts, equipment, materials
or services provided by third-party suppliers in fulfilling the Operator's
obligations under this Agreement.  The Operator shall comply with all
applicable warranties and guarantees provided by manufacturers or
contractors, and shall take no action that in any way impairs any rights
or claims of the SPV under any manufacturer's, supplier's or other party's
warranty.  Without limiting the foregoing, the Operator shall use spare
parts that will not adversely affect the SPV's protections or rights under
such warranties or guarantees.

    V.  Operation and Maintenance.  The Operator shall operate and maintain
the Project throughout the term of this Agreement and shall provide the
following services hereunder:
<PAGE>                                -28-<PAGE>
            A.  Prior to the Operation Commencement Date.  Prior to the
    Operation Commencement Date, the Operator shall, at its own cost and
    expense:

              (i)  (A)  secure or prepare an operations and maintenance
            manual (the "Operations Manual").  Such Operations Manual shall
            include all procedures necessary to operate the Project in
            compliance with this Schedule 1, and (B) upon approval of the
            Operations Manual by the Independent Engineer, the Operator shall
            develop and implement additional operating and maintenance
            procedures for the Project as may be necessary or appropriate for
            purposes of safety or for the efficient operation of the Project
            (the "O&M Procedures").  The Operator shall reference the
            previously supplied Operations Manual and develop and implement
            such supplemental procedures, as necessary or advisable, for
            equipment, components, systems or other portions of the Project. 
            The O&M Procedures shall, among other things, include (A)
            Project-specific preventive maintenance procedures, (B) adequate
            safety and fire prevention measures and procedures, including,
            safety procedures for the safe operation and maintenance of
            primary Project equipment, and (C) adequate security measures and
            procedures.  With respect to the maintenance of the Project, the
            O&M Procedures shall provide for the development of an annual
            major maintenance schedule defining outage time for regular
            overhaul work to be performed on the Project.

              (ii)  As the General Contractor approaches completion of
    construction of the Project in accordance with the Transaction
    Documents, an orderly transition shall occur from construction (under
    the control and supervision of the General Contractor) to operation
    (under the control and supervision of the Operator).  The Operator
    shall participate in an orderly process of transition from construction
    through check-out, completion, start-up, testing and acceptance of the
    Project by the SPV.  During the period prior to the Operation
    Commencement Date, Operator shall use its best efforts to cooperate and
    coordinate with the General Contractor.

              (iii)  Comply with the obligations, if any, imposed upon the
            Operator or any Affiliate of the Operator under the Project
            Contracts during the period of testing, said compliance to
            continue after the Operation Commencement Date.

            B.  Commencing on Operation Commencement Date.  Commencing on the
    Operation Commencement Date, the Operator shall, as authorized by the
    then applicable Project Budget:

              (i)  provide all services necessary or advisable to use,
            operate and maintain the Project in good operating condition and
            in compliance with this Schedule 1, the Operations Manual, the
            O&M Procedures and the other applicable provisions of this
            Agreement;

              (ii)  subject to the requirements of any prior approvals as set
            forth in Section 1.3 hereof, make payments for necessary
            Operation and Maintenance Costs;
<PAGE>                                -29-<PAGE>
              (iii)  review all Applicable Laws establishing compliance
            requirements in connection with the Operating Work; secure or
            renew, as necessary, appropriate Governmental Approvals required
            by any Person for the ownership and operation of the Project;

              (iv)  establish and maintain a complete inventory of the
            Project (including but not limited to those items outlined in (v)
            and (vi) below owned by the SPV) and review and update the
            inventory at least semi-annually;

              (v)  provide in accordance with the applicable Project Budget,
            all materials, supplies, parts, equipment, vehicles and other
            items necessary for the operation and maintenance of the Project,
            which are in addition to the Project as constructed and which are
            not required to be provided by the Owner pursuant to Article 2
            hereof (in which case, the Operator shall cause the Owner to
            provide the same);

              (vi)  maintain an appropriate spare parts inventory for other
            components of the Project and replace equipment, material or
            parts in the inventory as necessary or advisable from time to
            time (including equipment, material and parts necessary for the
            operation of a scale for weighing kiln feed for the Project
            Kilns, unless such function is already being adequately performed
            at the Black River Facility by another Person).  The Operator
            shall periodically review the adequacy of the spare parts
            inventory and procedures for the automatic replacement of spare
            parts;

              (vii)  make available all equipment, tools and clothing as are
            necessary to accomplish routine maintenance and major and
            emergency repairs to the components of the Project including, but
            not limited to, cranes, forklifts, electronic test equipment and
            special tools, if any, recommended by the manufacturer of the
            components;

              (viii)  perform, or cause to be performed by subcontractors,
            all rebricking and other maintenance activities required
            consistent with the Transaction Documents, the Operations Manual
            and the O&M Manuals to maintain the Project in good working
            condition and capable of operating at maximum profitability,
            consistent with Prudent Industry Practice (including
            recalibrating the scale for weighing kiln feed for the Project
            Kilns as necessary, unless such function is already being
            adequately performed at the Black River Facility by another
            Person).  Make changes to the Operations Manuals and O&M
            Procedures, if required or desirable, in order to facilitate
            efficient and safe operation and maintenance of the Project;

              (ix)  provide administrative and procurement services related
            to the Operating Work as necessary;

              (x)  retain any failed components for inspection if required by
            manufacturers' and suppliers' insurance carriers, and cooperate
            with such carriers' personnel regarding such inspections;
<PAGE>                                -30-<PAGE>
              (xi)  provide commercially reasonable safety and security
            measures for the Project;

              (xii)  maintain complete and accurate records of all operation
            and maintenance activities relating to the Project and maintain
            any operating logs which the SPV may be required to prepare under
            the Transaction Documents or which are required under any
            warranties or any insurance policies;

              (xiii)  deliver processed lime to OPCO in accordance with the
            OPCO Agreement, bill OPCO for deliveries made and check the
            payments made by OPCO under the OPCO Agreement, and take any
            actions necessary to collect amounts owed by OPCO under the OPCO
            Agreement.

              (xiv)  coordinate for the SPV and implement all manufacturers'
            requirements for plant data reports and warranty claims and, as
            appropriate, provide recommendations as to revisions to the
            Operations Manual and O&M Procedures;

              (xv)  provide all technical support and other services
            reasonable and necessary for the operation and maintenance of the
            Project;

              (xvi)  provide notices to the SPV and the Collateral Agent, all
    in reasonable detail and promptly upon learning of the event requiring
    notice, as follows:

                           (a)  notice of any material occurrence which is
                         covered by any warranty given by the manufacturer of
                         any part of, or equipment relating to, the Project;

                           (b)  notice of any actual or potential material
                         violation of any Applicable Law, including, without
                         limitation, Environmental Laws; and

                           (c)  notice of all events, occurrences, conditions
                         and issues of which Operator shall become aware and
                         which the Operator reasonably considers are material
                         to, or are likely to have a material effect on, the
                         Project or the operation, maintenance or results of
                         operations thereof (including notice of any occurrence
                         of any Event of Default or Loss Event), and shall
                         endeavor to keep the SPV informed on a timely basis
                         with regard thereto.  Without limiting the generality
                         of the foregoing, all notices of Liens and claims of
                         Liens shall be deemed material to the Project;

              (xvii)  provide written recommendations to the SPV of actions

                                               SCHEDULE 2

                                     OPERATION AND MAINTENANCE COSTS



    During the term of the Agreement, Operation and Maintenance Costs shall
be determined as follows:

    1.  coal/petroleum coke - actual incremental cost of coal/petroleum
coke consumed in operating the Project;

    2.  electricity - actual incremental cost of electricity consumed in
operating the Project;

    3.  insurance - actual incremental cost of insurance attributable to
Project;

    4.  actual incremental property taxes attributable to the Project;

    5.  labor - actual incremental cost of operating the Project and mining
limestone and delivering limestone to the Project Kilns;

    6.  scheduled recurring capital expenditures for the Project actually
    made;

    7.  actual incremental expenses incurred pursuant to Section
1.4(c)(iii) hereof; and

    8. actual incremental other costs for materials, supplies, mining and
maintaining the Project ("Other Costs") - for purposes of disbursements to
be made pursuant to Section 2.2(b)(ii)(A) of the Deposit and Disbursement
Agreement in any month, the "Other Costs" component of Operation and
Maintenance Costs shall be deemed to be the "Other Costs" projected for
such month in the current Project Budget.  Beginning in the second month
after the Conversion Date and every month thereafter, there shall be a
reconciliation of the previous month's projected "Other Costs" versus the
actual amount thereof, and the disbursement to be made pursuant to Section
2.2(b)(ii)(A) of the Deposit and Disbursement Agreement on the fifteenth
(15th) day of such following month shall be increased or decreased, as the
case may be, to reflect actual "Other Costs" incurred for such previous
month.  "Other Costs" shall in no event include any costs related to any
item listed in entries 1 to 7, inclusive on this Schedule 2.

    Operation and Maintenance Costs shall be determined using a methodology
consistent with the methodology used in preparing the incremental analysis
of costs attached to this Schedule 2 as Schedule 2-A.

1.    APPOINTMENT OF DISBURSEMENT AGENT; ESTABLISHMENT OF THE ACCOUNTS

      1.1   Acceptance of Appointment of Disbursement Agent.

            (a)   Acceptance of Appointment.  The Disbursement Agent is
      hereby appointed and agrees to act as the Disbursement Agent for all
      Project Revenues and all other revenues, receipts, monies, proceeds
      and other sums derived in any manner from or constituting the

<PAGE>                                -1-<PAGE>
      
      (b)   No SPV Rights.    Neither the SPV nor any Affiliate thereof
shall have any rights against the Disbursement Agent (other than rights
which may arise as a result of the Disbursement Agent's gross negligence
or wilful misconduct), as a third party beneficiary or otherwise, including,
without limitation, any right to direct the Disbursement Agent to distribute
or allocate any funds in the Accounts.  Any withdrawal, transfer or
investment made or caused to be made in accordance with the provisions
hereof is expressly understood to be made with the permission of the
parties hereto.  In performing its functions and duties under this
Agreement, the Disbursement Agent shall act solely as agent for the
Collateral Agent and does not assume and shall not be deemed to have
assumed any obligation toward, or relationship of agency or trust with or
for, the SPV or any of its Affiliates.

      1.2   Creation of the Accounts.

            (a)   Accounts.   The Disbursement Agent hereby establishes
      the following special, segregated and irrevocable cash collateral
      accounts which shall be maintained at all times until the termination
      of this Agreement:

            (i)   Construction Account,

            (ii)  Project Revenue Account,
            (iii) Debt Service Reserve,

            (iv)  Additional Reserve,

            (v)   Default Reserve,

            (vii) Construction Completion Account, and 
            (viii)Windup Account.
            The account number for each Account is set forth on Schedule I
      hereto.  All amounts from time to time in any Account shall be held in
      the name of the Disbursement Agent for the benefit of the Collateral
      Agent.  All amounts at any time in any of the Accounts shall
      constitute a part of the SPV Collateral and shall not constitute
      payment of any obligation owing to the Holders until applied as
      hereinafter provided.

            (b)   Bailment.   The Collateral Agent hereby appoints the
      Disbursement Agent as its bailee of the SPV Collateral held by the
      Disbursement Agent hereunder, subject to the terms and conditions of
      this Agreement.

      1.3   Security Interests; Revenues; Miscellaneous.

            (a)   Security Interests in Project Revenues.   Each of the

      upon the acknowledgment of the other 
<PAGE>                                -2-<PAGE>
      parties, without independent knowledge or investigation) hereby
      acknowledges that (i) the SPV has assigned the SPV Collateral
      (including the Accounts) to the Collateral Agent pursuant to the SPV
      Security Agreement and the other Transaction Documents.  It is
      pursuant to the Collateral Agent's rights as holder of a security
      interest in the SPV Collateral that the Collateral Agent has the right
      to appoint a Disbursement Agent hereunder and otherwise has rights
      under this Agreement.

            (b)   Direct Deposit of Project Revenues And Other Amounts. 
      Subject to Section 2.8, the SPV agrees to arrange, and hereby
      confirms that it has arranged, for the direct payment to the
      Disbursement Agent (for the benefit of the Collateral Agent) of all
      Project Revenues.  The SPV hereby agrees that all Project Revenues
      shall be deposited in the Project Revenue Account.  To the extent any
      Project Revenues or other amounts (except the amounts specified in
      clauses (i) through (iii) of the definition of Project Revenues in
      Annex A to the Note Purchase Agreement) are at any time received by
      the SPV, the SPV will hold all Project Revenues and other such
      amounts (including all Substitute OPCO Revenues (as defined in
      Section 2.3(c) hereof)) in trust for the benefit of the Collateral
      Agent and will pay Project Revenues and other such amounts to the
      Disbursement Agent for deposit into the Project Revenue Account on
      the Business Day following receipt thereof (duly endorsed, if
      necessary, to the Disbursement Agent).  Without limiting the
      generality of the foregoing, the SPV has instructed OPCO and any
      other Person to which it sells lime or any other commodity, or to which
      it provides any other services, to pay directly to the Disbursement
      Agent for deposit in the Project Revenue Account all amounts payable
      under the OPCO Agreement or otherwise and, with respect to other
      such Persons, the related agreement.

            (c)   UCC Filings.      The Disbursement Agent shall take such
      action as may be requested by the SPV or the Collateral Agent in
      order to comply with the provisions of the Uniform Commercial Code (as
      in effect in any applicable jurisdiction) governing the establishment,
      preservation, protection or perfection of security interests in the
      Accounts.

2.    DEPOSITS INTO AND DISBURSEMENTS FROM ACCOUNTS

            The SPV hereby authorizes the Disbursement Agent to make the
      following deposits and withdrawals with respect to the Accounts.  All
      obligations with regard to deposits and disbursements set forth in
      any provision of this Section are subject to the wind-up provisions
      set forth in Section 2.8 and the cure rights set forth in Section 2.9.


      2.1   Construction Account.

            (a)   Deposits.   The Disbursement Agent shall deposit into the
      Construction Account (i) all amounts advanced by the Lender pursuant
      to the Note Purchase Agreement and transferred by the Lender to the
      Disbursement Agent for deposit into the Construction Account and (ii)
      all amounts contributed by Lime, through the Partners, pursuant to
      Section 3.15 of the Lime Security Agreement and transferred by Lime
      to the Disbursement Agent for deposit into the Construction Account.
<PAGE>                                -3-<PAGE>
            (b)   Disbursements.  The Disbursement Agent shall disburse
      funds in the Construction Account, within one Business Day of its
      receipt of such funds, to the Persons and in the amounts set forth in
      the Approved Draw Request pursuant to which such funds were
      advanced by the Lender.  In addition, on the Conversion Date, after
      giving effect to the Advance, if any, to be made on such date
      pursuant to the Note Purchase Agreement, and upon (i) the purchase
      of the Term Notes by the Lender on such date and (ii) the
      disbursement of funds, if any, into the Construction Completion
      Account and the Debt Service Reserve in compliance with Section 8.19
      of the Note Purchase Agreement, the Disbursement Agent shall
      disburse to the SPV all moneys on deposit in the Construction Account
      up to, but not in excess of, Five Million Three Hundred Thousand
      Dollars ($5,300,000).


      2.2   Project Revenue Account.

            (a)   Deposits.  The Disbursement Agent shall deposit in the
      Project Revenue Account all moneys required to be deposited into the

      provisions hereof or any other Transaction Document, and all Project
      Revenues and other amounts required to be deposited into the Project
      Revenue Account by Section 1.3(b) hereof, including, without limitation:

                  (i)   all payments received from the Operator and the
            Owner under the MCFA; and

                  (ii)  all payments received from OPCO or any other
            Person for goods or services supplied by the Project.


      If the conditions for disbursement from any Account to the Project
      Revenue Account have been satisfied on any Debt Payment Date
      (whether due to an overfunding of such Account or otherwise), the
      amount to be disbursed from the Project Revenue Account on such date
      shall include the amount to be disbursed from such other Account to
      the Project Revenue Account on such date.

            (b)   Disbursements.  

                  (i)   If, prior to the Conversion Date, funds are
            deposited into the Project Revenue Account in respect of sales
            of processed lime other than Substitute OPCO Revenues, the
            Disbursement Agent shall disburse from the Project Revenue
            Account to the Operator so long as the Operator is not in
            default of its obligations under the MCFA (or if any such
            default exists, the grace period, if any, in respect thereof has
            not expired (it being understood that "grace period" does not
            include any cure period referred to in Section 6 of the
            Intercreditor Agreement)), the Operation and Maintenance Costs
            attributable to such sales of lime as determined in accordance
            with the methodology to be observed in determining Operation
            and Maintenance Costs under Project Budgets, as specified in a
            certificate (in the form of Exhibit A hereto) executed by Lime
            and delivered by the SPV to the 
<PAGE>                                -4-<PAGE>
            Disbursement Agent and the Lender at least 5 days before such
            disbursement is to be made.

                  (ii)  From and after the Conversion Date, the
            Disbursement Agent shall disburse from the Project Revenue
            Account, in the following order of priority, on each Debt
            Payment Date (except with respect to subclause (A) below in
            which event disbursements shall be made as therein provided),
            so that, if there shall be insufficient funds in the Project
            Revenue Account to make all payments then due, no payment set
            forth below shall be made until all amounts owing in respect of
            all payments then due with a higher priority shall have been
            paid in full:

                        (A)   First,

                              (1)   on the first Business Day of each month,
                        to the Disbursement Agent and the Collateral Agent,
                        all amounts due and owing in respect of fees and
                        expenses of the Disbursement Agent and the
                        Collateral Agent, as specified in a certificate (in
                        the form of Exhibit B hereto) executed by the
                        Disbursement Agent or the Collateral Agent, as the
                        case may be, delivered to the Disbursement Agent
                        and the Lender at least 5 days before such
                        Business Day;

                              (2)   on Thursday of each week, to the
                        Operator an amount due in respect of the Operator's
                        payroll for the preceding week as specified in a
                        certificate (in the form of Exhibit C hereto)
                        executed by the Operator and delivered to the
                        Disbursement Agent at least 2 Business Days prior
                        to such date;

                              (3)   on the first and fifteenth days of each
                        month, to Lime so long as Lime is not in default of
                        its obligations under the MCFA (or if any such
                        default exists, the grace period, if any, in respect
                        thereof has not expired (it being understood that
                        "grace period" does not include any cure period
                        referred to in Section 6 of the Intercreditor
                        Agreement)), the amount due and owing under the
                        MCFA including, without limitation, Operation and
                        Maintenance Costs and the costs of lime production
                        at the Maysville Facility and the Black River
                        Facility payable by the SPV pursuant to Section 3.4
                        of the MCFA and not required to be disbursed
                        pursuant to Section 2.3(b)(i) hereof, as specified in
                        a certificate (in the form of Exhibit D hereto)
                        executed by Lime and delivered by the SPV to the
                        Disbursement Agent and the Lender at least 5 days
                        before such date; and

                              (4)   if the amounts on deposit in the Project
                        Revenue Account are insufficient to pay all such
                        fees and expenses, on any date, then ratably to the
                        Persons owed such amounts in accordance with the
                        respective amounts owing to each on such date;
<PAGE>                                -5-<PAGE>
                  provided that no such payment shall be made pursuant to
                  this subclause (A) in respect of any expenditure if such
                  expenditure would violate any provision of Section 1.4(c)
                  of the MCFA.

                        (B)   Second, to the account specified in Schedule
                  III hereto in partial satisfaction of the SPV's obligation
                  to pay Debt Service an amount equal to the sum of (1) the
                  Debt Service Payment then due and payable, plus (2) the
                  aggregate amount, if any, of all prior Debt Service that
                  remains unpaid on such Debt Payment Date (together with
                  interest on such unpaid amount at the Late Payment Rate);

                        (C)   Third, to the Debt Service Reserve, all
                  remaining amounts in the Project Revenue Account until no
                  further deposits are required to be made into the Debt
                  Service Reserve, as set forth in Section 2.3(a);

                        (D)   Fourth, to the Additional Reserve, the amount,
                  if any, required to be deposited therein pursuant to
                  Section 2.4(a);

                        (E)   Fifth, to the Default Reserve, the amount, if
                  any, required to be deposited therein pursuant to Section
                  2.5(a);

                        (F)   Sixth, to Lime, all amounts remaining after the
                  payments required by the foregoing clauses (A) to (E),
                  inclusive.

      2.3   Debt Service Reserve.

            (a)   Deposits.   The Disbursement Agent shall deposit into the
      Debt Service Reserve the following amounts:

                  (i)   prior to the Conversion Date, all Substitute OPCO
            Revenues which may at any time have been paid to the Project
            Revenue Account, immediately upon the receipt thereof, 

                  (ii)  on the Conversion Date, such amounts, if any, as are
            (x) borrowed on the Conversion Date by the SPV pursuant to
            Section 1.4 of the Note Purchase Agreement and paid to the
            Disbursement Agent in respect of the Required Reserve Payment
            as specified in a certificate (in the form of Exhibit E hereto)
            delivered to the Disbursement Agent by the SPV and (y) payable
            by Lime pursuant to Section 3.15 of the Lime Security Agreement,
            and 

                  (iii) from and after the Conversion Date, 100% of Excess
            Cash Flow from the Project Revenue Account,

      until the aggregate amount on deposit in the Debt Service Reserve
      shall equal One Year's Debt Service.

            (b)   Disbursements.
<PAGE>                                -6-<PAGE>
                  (i)   Prior to the Conversion Date, the Disbursement
            Agent shall disburse from the Debt Service Reserve on the
            first and fifteenth days of each month, to Lime so long as Lime
            is not in default of its obligations under the MCFA (or if any
            such default exists, the grace period, if any, in respect
            thereof has not expired (it being understood that "grace period"
            does not include any cure period referred to in Section 6 of the
            Intercreditor Agreement)), the amount due and owing to Lime
            under Section 3.4 of the MCFA, as specified in a certificate (in
            the form of Exhibit F hereto) executed by Lime and delivered by
            the SPV to the Disbursement Agent and the Lender at least 5
            days before such date.

                  (ii)  The Disbursement Agent shall disburse funds from
            the Debt Service Reserve to the Lender on each Debt Payment
            Date if the amount available for disbursement on such date
            from the Project Revenue Account for the payment of Debt
            Service due on or prior to such date shall be less than the
            amount of such Debt Service (the amount of such shortfall being
            referred to herein as the "Debt Service Shortfall").  The amount
            of such disbursement shall be equal to the lesser of (x) the
            Debt Service Shortfall minus any amount applied to the Debt
            Service Shortfall from the Additional Reserve and (y) the
            amount on deposit in the Debt Service Reserve.

                  (iii) Upon receipt of a certificate (in the form of Exhibit
            G hereto) executed by the SPV and the Collateral Agent in
            respect of an overfunding of the Debt Service Reserve, the
            Disbursement Agent shall disburse funds from the Debt Service
            Reserve to the Project Revenue Account on each Debt Payment
            Date to the extent that the aggregate amount on deposit in the
            Debt Service Reserve shall exceed One Year's Debt Service
            (whether by reason of interest and other sums earned in
            respect of the Debt Service Reserve or otherwise), as specified
            in such certificate.  The Collateral Agent shall be obligated to
            deliver such a certificate to the Disbursement Agent after it
            has received evidence satisfactory to it from the SPV that any
            such excess shall exist.

            (c)   Definitions.      As used in this Agreement, the following
      terms shall have the following meanings:

                  (i)   "Excess Cash Flow" means, as of any date of
            determination and for any period, the amount by which

                        (A) the aggregate amount of all Project Revenues in
                  respect of such period paid on or prior to the date of
                  determination, exceeds

                        (B) the aggregate amount of disbursements required
                  to be made by the Disbursement Agent during such period
                  (whether or not actually made) pursuant to subclauses (1)
                  through (4), inclusive, of Section 2.2(b)(ii)(A) and pursuant
                  to Section 2.2(b)(ii)(B).

                  (ii)  "One Year's Debt Service" means, the largest
            aggregate amount of principal and interest scheduled to be paid
            in respect of the Notes during any 
<PAGE>                                -7-<PAGE>
            period of twelve consecutive months ending on or prior to the
            maturity of the Term Notes, in each case as determined by
            reference to Schedule II hereto.

                  (iii) "Substitute OPCO Revenues" means all amounts
            payable by OPCO under the OPCO Agreement in respect of lime
            which was not processed by the Project.

      2.4   Additional Reserve.

            (a)   Deposits.   If, either

                  (i)   on any Debt Payment Date, the Debt Service
            Coverage Ratio for the Interim Period most recently ended as of
            such date was equal to or less than 1.30 to 1, or

                  (ii)  on any Debt Payment Date, the Projected Debt
            Service Coverage Ratio for each of the two consecutive Interim
            Periods immediately following such most recently ended Interim
            Period is equal to or less than 1.30 to 1, 
            
      then, on such Debt Payment Date and on each Debt Payment Date
      thereafter, upon receipt of a certificate (in the form of Exhibit H
      hereto) (an "Additional Reserve Certificate") executed by the
      Collateral Agent in respect of such conditions, the Disbursement
      Agent shall disburse 100% of Excess Cash Flow, net of any deposits
      required to be made into the Debt Service Reserve pursuant to
      Section 2.3(a), from the Project Revenue Account and deposit such sum
      into the Additional Reserve until the Debt Payment Date on which both
      (x) the Debt Service Coverage Ratio for each of the two then most
      recently ended Interim Periods, and (y) the Projected Debt Service
      Coverage Ratio for each of the two consecutive Interim Periods
      immediately following the then most recently ended Interim Period,
      shall be equal to or greater than 1.40 to 1.  Effective as of the Debt
      Payment Date on which both of the conditions set forth in the
      foregoing subclauses (x) and (y) shall be satisfied, but only upon its
      receipt of an Additional Reserve Certificate executed by the
      Collateral Agent in respect of such conditions, the Disbursement
      Agent shall make no further such disbursements from the Project
      Revenue Account pursuant to this Section 2.4(a) but all Excess Cash
      Flow theretofore deposited into the Additional Reserve pursuant to
      this Section 2.4(a) shall remain on deposit therein (subject to
      disbursement as provided herein); provided, however, that, at such
      time as either of the conditions set forth in the foregoing clauses (i)
      and (ii) shall again be satisfied, and upon its receipt of an
      appropriate Additional Reserve Certificate, the Disbursement Agent
      shall again make the deposits provided for in the first sentence of
      this Section 2.4(a).  The Collateral Agent shall be obligated to deliver
      an appropriate Additional Reserve Certificate to the Disbursement
      Agent if, after either of the conditions set forth in the foregoing
      clauses (i) and (ii) have occurred, it shall have received evidence
      satisfactory to it from the SPV that both of the conditions set forth
      in the foregoing clauses (x) and (y) have been satisfied.

            (b)   Disbursements.

                  (i)   The Disbursement Agent shall disburse funds from
            the Additional Reserve to the Lender on any Debt Payment Date
            if there shall be a Debt Service 
<PAGE>                                -8-<PAGE>
            Shortfall on such date.  The amount of such disbursement shall
            be equal to the lesser of (A) the Debt Service Shortfall for
            such date and (B) the amount on deposit in the Additional
            Reserve.

                  (ii)  If, on any Debt Payment Date,

                        (A)   the Debt Service Coverage Ratio for each of
                  the two then most recently ended Interim Periods was
                  equal to or greater than 1.50 to 1 and

                        (B)   the Projected Debt Service Coverage Ratio for
                  each of the two consecutive Interim Periods immediately
                  following the then most recently ended Interim Period is
                  equal to or greater than 1.50 to 1,

            the Disbursement Agent shall, upon receipt of a certificate (in
            the form of Exhibit I hereto) (an "Additional Reserve
            Disbursement Certificate") executed by the SPV and the
            Collateral Agent in respect of such conditions, disburse all
            amounts on deposit in the Additional Reserve and deposit such
            funds into the Project Revenue Account for disbursement as
            provided in Section 2.2.  The Collateral Agent shall be obligated
            to deliver an Additional Reserve Disbursement Certificate to
            the Disbursement Agent after it shall have received evidence
            satisfactory to it from the SPV that the conditions set forth in
            the foregoing clauses (A) and (B) have been satisfied.

                  (iii) As used in this Section 2.4, the following terms
            shall have the following meanings:

                        (A)   "Projected Debt Service Coverage Ratio"
                  means, for any period, the ratio of

                              (1) the amount of all Project Revenues
                        projected to be paid during such period minus the
                        aggregate amount of disbursements projected to be
                        made by the Disbursement Agent during such period
                        pursuant to subclause (A) of Section 2.2(b)(ii), to

                              (2) the aggregate amount of disbursements
                        projected to be made by the Disbursement Agent
                        during such period in respect of payments pursuant
                        to subclause (B) of Section 2.2(b)(ii),

                  in each case as set forth in the Project Budget (or the
                  Extended Project Budget if applicable) delivered to the
                  Disbursement Agent and the Collateral Agent in respect of
                  such period.

                        (B)   "Debt Service Coverage Ratio" means, as of
                  any date of determination and for any period, the ratio of

                              (1) the amount of all Project Revenues in
                        respect of such period paid on or prior to the date
                        of determination, minus the
<PAGE>                                -9-<PAGE>
                        disbursements required to be made by the
                        Disbursement Agent during such period (whether or
                        not actually made) pursuant to subclause (A) of
                        Section 2.2(b)(ii), to

                              (2) the aggregate amount of disbursements
                        required to be made by the Disbursement Agent
                        during such period in respect of payments (whether
                        or not actually made) pursuant to subclause (B) of
                        Section 2.2(b)(ii).

      2.5   Default Reserve.

            (a)   Deposits.   On any Debt Payment Date when an Event of
      Default exists, unless otherwise instructed by the Collateral Agent,
      and so long as no deposits are required to be made into the Additional
      Reserve on such date pursuant to Section 2.4(a) (it being understood
      that no deposit shall be made into the Default Reserve at any time if
      a deposit is required to be made into the Additional Reserve at such
      time), the Disbursement Agent shall disburse 100% of Excess Cash
      Flow, net of any deposits required to be made into the Debt Service
      Reserve pursuant to Section 2.3(a), from the Project Revenue Account
      and deposit such amount into the Default Reserve; provided, however,
      that if,

                  (i)   (A) on the immediately preceding Debt Payment Date
            one or more Dravo-Related Defaults existed and no other Event
            of Default existed, and (B) the Disbursement Agent made the
            disbursement and deposit in respect thereof, as contemplated
            by this Section 2.5(a), and

                  (ii)  on such then current Debt Payment Date, the only
            Event of Default in existence is the Dravo-Related Default or
            Dravo-Related Defaults that were in existence on such
            immediately preceding Debt Payment Date,

      then no such disbursement and deposit shall be made on such then
      current Debt Payment Date.  All amounts deposited into the Default
      Reserve at any time when an Event of Default, other than a Dravo-
      Related Default, exists shall remain on deposit in the Default
      Reserve, regardless of whether such Event of Default shall
      thereafter be cured or otherwise cease to exist, and regardless of
      whether a Dravo-Related Default existed at the same time as such
      Event of Default.

            (b)   Disbursements.    All amounts deposited into the Default
      Reserve at any time when the only Event of Default which exists is a
      Dravo-Related Default shall remain on deposit in the Default Reserve
      until the first Debt Payment Date on which no Event of Default shall
      exist, at which time such amounts shall be disbursed from the Default
      Reserve and deposited into the Project Revenue Account for
      disbursement as provided in Section 2.3(b).

            (c)   Knowledge of Defaults.  The Disbursement Agent shall not
      be deemed to have knowledge of an Event of Default unless and until
      it shall have received notice thereof from the SPV, the Lender or the
      Collateral Agent, and shall assume that no Event of Default exists
      except Events of Default in respect of which it shall have received
      such 
<PAGE>                                -10-<PAGE>
      notice.  The Disbursement Agent shall assume that each Event of
      Default of which it has received notice is continuing until such time
      as it shall receive notice from the Lender or the Collateral Agent
      that such Event of Default has been cured.  The Collateral Agent
      shall be obligated to deliver such notice to the Disbursement Agent
      promptly after it receives notice from the Holders that any Event of
      Default has been cured.

      2.6   Casualty Account.

            (a)   Deposits.   Each party hereto acknowledges and agrees
      that if it shall receive any proceeds (other than proceeds of any
      business interruption policy) in respect of a Loss Event
      (collectively, "Casualty Proceeds") which is a Partial Loss, such party
      shall promptly remit such Casualty Proceeds (less the actual costs,
      fees, and expenses incurred in the collection thereof as certified in
      a certificate executed by the SPV or Lime) to the Disbursement Agent
      for deposit into the Casualty Account, together with a certificate
      stating the source of the Casualty Proceeds, a detailed description
      of the Partial Loss giving rise to such party's receipt thereof, and
      instructions to deposit such Casualty Proceeds into the Casualty
      Account.  Until such time that such party shall remit such Casualty
      Proceeds to the Disbursement Agent, it shall hold such proceeds in
      trust for the benefit of the Disbursement Agent for application as
      provided herein.

            (b)   Disbursements.

                  (i)   If (A) the aggregate Casualty Proceeds received by
            the Disbursement Agent in respect of any single Partial Loss
            shall not exceed Five Hundred Thousand Dollars ($500,000), (B)
            the SPV shall, at least ten days prior to any disbursement
            pursuant to this Section 2.6(b), deliver to the Disbursement
            Agent and the Lender a certificate (in the form of Exhibit J)
            setting forth, inter alia, a detailed description of the repairs
            to be effected with such Casualty Proceeds, a certification
            that the sum of (x) the amount of such Casualty Proceeds, plus
            (y) the applicable deductibles and self-insured amounts under
            the SPV's insurance policies, is not less than the amount of
            such repairs and an undertaking to complete such repairs, and
            (C) no Event of Default shall exist at the time of proposed
            disbursement, the Disbursement Agent shall disburse such
            Casualty Proceeds to (or at the direction of) the SPV in the
            amounts specified in such certificate.

                  (ii)  If the aggregate Casualty Proceeds received by the
            Disbursement Agent in respect of any single Partial Loss shall
            exceed Five Hundred Thousand Dollars ($500,000) and no Event
            of Default shall exist, the Disbursement Agent shall disburse
            such proceeds to the SPV from time to time, in each case upon
            presentation to the Disbursement Agent of a request therefor,
            approved by the Independent Engineer:  (A) specifying the
            amount so to be disbursed, (B) annexing invoices (not previously
            used as a basis for any disbursement of funds pursuant to this
            Section 2.6(b)(ii)) demonstrating expenditures made or to be made
            by the SPV upon receipt of such funds for repair and/or
            replacement of the Project and (C) certifying that (i) such
            repair and/or replacement is technically feasible for a cost
            not in excess of the sum of (x) the amount of available Casualty
            Proceeds plus (y) the applicable deductibles and self-insured
            amounts under the 
<PAGE>                                -11-<PAGE>
            SPV's insurance policies, and (2) such repair and/or restoration
            is proceeding in compliance with the SPV's obligations under
            Section 11.2 of the Note Purchase Agreement and the other
            Transaction Documents.

            (c)   Knowledge of Defaults.  The Disbursement Agent shall
      determine the existence or non-existence of an Event of Default in
      the manner provided in Section 2.5(c).

      2.7   Construction Completion Account.

            (a)   Deposits.   On the Conversion Date, the SPV, pursuant to
      Section 8.19 of the Note Purchase Agreement, shall deposit into the
      Construction Completion Account an amount equal to 100% of the
      aggregate cost of completing the Punch List Items.

            (b)   Disbursements.    From time to time, upon the request of
      the SPV (or Lime as Construction Manager) made pursuant to a
      certificate (in the form of Exhibit K hereto) approved by the
      Independent Engineer and the Lender and delivered to the
      Disbursement Agent at least five days prior to the proposed
      disbursement date, the Disbursement Agent shall disburse from the
      Construction Completion Account the amount set forth in such
      certificate to pay the cost of completed Punch List Items.  Such
      disbursement shall be made directly to Lime for payment to such
      Persons as the SPV shall specify in such certificate.  Following
      receipt by the Disbursement Agent of a notice from the SPV that all
      Punch List Items have been completed and the cost thereof has been
      paid, the Disbursement Agent shall disburse any remaining balance in
      the Construction Completion Account and deposit such balance into
      the Project Revenue Account.

      2.8   Windup Account.

            (a)   Deposits.   The Disbursement Agent shall deposit into the
      Windup Account any of the following amounts received from any
      Person:

                  (i)   Casualty Proceeds (less the actual costs, fees and
            expenses incurred in the collection thereof as certified in a
            certificate executed by the SPV or Lime) received as a result of
            the occurrence of a Total Loss; and

                  (ii)  all amounts received as a result of the exercise of
            any remedy under any Transaction Document.

            (b)  Disbursements.

                  (i)   Any provision of this Agreement to the contrary
            notwithstanding (subject, however, to the proviso set forth
            below), upon receipt of a certificate (in the form of Exhibit L
            hereto) executed by the Collateral Agent stating that a Windup
            Event has occurred and is continuing and specifying the nature
            of same, the Disbursement Agent shall not make any further
            transfers pursuant to any Section of this Agreement other
            than this Section 2.8 and shall transfer to the Windup Account
            (x) all amounts then on deposit in all other Accounts and (y) all
<PAGE>                                -12-<PAGE>
             Project Revenues and other amounts then held or subsequently
            received by the Disbursement Agent which would otherwise have
            been deposited in any Account.  On the date or dates specified
            in such certificate or in a subsequent certificate executed by
            the Collateral Agent, the Disbursement Agent shall make
            disbursements from the Windup Account in the following order of
            priority (so that, if there shall be insufficient funds to make
            all such payments, no payment set forth below shall be made
            until all amounts owing in respect of all payments with a higher
            priority shall have been paid in full):

                        (A)   First, to the payment of the costs and
                  expenses of foreclosure or suit, if any, and of the sale
                  of the Collateral, and all proper expenses, liability and
                  advances, including reasonable legal expenses and
                  attorneys' fees, incurred or made by the Collateral Agent
                  and the Disbursement Agent, and all taxes, assessments or
                  Liens superior to the Lien of the Collateral Agent on the
                  Collateral, except any taxes, assessments or other
                  superior Lien subject to which said sale may have been
                  made;

                        (B)   Second, to the payment of all reasonable
                  expenses, liabilities and advances, including reasonable
                  legal expenses and attorneys' fees, incurred or made by
                  the Holders;

                        (C)   Third, to the payment of the accrued and
                  unpaid interest on the Notes then outstanding, and, in
                  case such proceeds shall be insufficient to pay in full
                  such amounts, then ratably to each Holder according to
                  the aggregate principal amount of Notes held by each;

                        (D)   Fourth, to the payment of the unpaid principal
                  amount of the Notes then outstanding and, in case such
                  proceeds shall be insufficient to pay in full the entire
                  principal amount so unpaid, then ratably to each Holder
                  according to the aggregate principal amount of Notes held
                  by each;

                        (E)   Fifth, to the payment of the Make-Whole
                  Amount, if any, then unpaid with respect to the
                  outstanding Notes and, in case such proceeds shall be
                  insufficient to pay in full such amounts, then ratably to
                  each Holder according to the principal amount of Notes
                  held by each;

                        (F)   Sixth, to the payment of all other amounts
                  owed with respect to the Notes and the other Secured
                  Obligations and, in case such proceeds shall be
                  insufficient to pay in full such amounts, then ratably to
                  each holder thereof; and

                        (G)   Seventh, to Lime or to whomever else may be
                  entitled thereto pursuant to the Transaction Documents
                  or applicable law.

                  (ii)  As used herein, "Windup Event" means the occurrence
            of any of the following events:
<PAGE>                                -13-<PAGE>
                        (A)   the occurrence of a Total Loss; or

                        (B)   the acceleration of the principal balance of
                  the Notes.

      2.9   Cure Rights.

      Any payments made to the Disbursement Agent by any Person
exercising any cure right pursuant to Article 6 of the Intercreditor
Agreement shall be deposited into the Account designated by such Person in
a notice accompanying such payment and shall be applied as herein provided. 
If no Account shall be designated, such amount shall be deposited into the
Project Revenue Account and applied as herein provided.

      2.10  Permitted Investments. 

      The Disbursement Agent shall invest any cash held in any Account
from time to time in Permitted Investments.  All such investments shall be
made so as to mature on or prior to the date or dates on which the
Disbursement Agent anticipates that funds therein will be required for
disbursements to be made hereunder (but the Disbursement Agent shall use
its best efforts to invest in Permitted Investments with the longest
available maturity consistent with such requirement).  Any income or gain
realized as a result of any such investment shall be held as part of the
applicable Account and reinvested as provided in this Agreement until
disbursed in compliance with this Section 2.  For purposes of any income tax
payable on account of any such income or gain, such income or gain shall be
for the account of the SPV.  The Disbursement Agent shall have no liability
for any loss resulting from any such investment other than by reason of
its wilful misconduct or gross negligence.  Any such investment may be
liquidated by the Disbursement Agent, in a manner intended to minimize any
loss of principal prior to maturity, whenever necessary to make any
deposit, distribution or transfer required by this Agreement.  The
Disbursement Agent shall not be liable to any Person for any investment
loss resulting from any such liquidation of investments.


      3.1   Appointment of Disbursement Agent; Powers and Immunities. 

            (a)   Appointment of Disbursement Agent.  The Collateral Agent,
      on behalf of the Lender, hereby irrevocably appoints and authorizes
      the Disbursement Agent to act as its agent hereunder, with such
      powers as are expressly delegated to the Disbursement Agent by the
      terms of this Agreement and such other powers as are reasonably
      incidental thereto; and the SPV consents to such appointment.

            (b)   Duties and Responsibilities.  The Disbursement Agent
      shall not have any duties or responsibilities except those expressly
      set forth in this Agreement.  Without limiting the generality of the
      foregoing, prior to satisfaction in full of the Secured Obligations,
      the Disbursement Agent shall take all actions as the Collateral Agent
      shall direct it in writing to perform in accordance with the provisions
      of this Agreement.  The Disbursement Agent shall not take any actions
      hereunder except in accordance with such instructions and shall be
      fully protected in acting, or in refraining from acting, hereunder in
      accordance with such instructions.  Notwithstanding anything to the
      contrary contained 
<PAGE>                                -14-<PAGE>
      herein, the Disbursement Agent shall not be required to take any
      action which is contrary to this Agreement or applicable law or which
      in its reasonable judgment would involve it in expense or liability
      unless it has been furnished with adequate indemnity to its
      reasonable satisfaction against such expense or liability.  The
      Disbursement Agent shall not have any duties or responsibilities
      except those expressly set forth herein and those necessarily
      incidental thereto, and no implied covenants, functions,
      responsibilities or duties on the part of the Disbursement Agent
      shall be read into this Agreement or shall otherwise exist against the
      Disbursement Agent.

            (c)   Disclaimer of Representations, etc. by Other Persons. 
      Neither the Disbursement Agent nor any of its Affiliates shall be
      responsible to any Person for any recitals, statements,
      representations or warranties made by any other Person contained in
      this Agreement or any other Transaction Document or in any
      certificate or other document referred to or provided for herein or
      therein, for the value, validity, effectiveness, genuineness,
      enforceability or sufficiency of this Agreement or any other
      Transaction Document or any other document referred to or provided
      for herein or therein, or for any failure by the SPV or the Collateral
      Agent, to perform their respective obligations hereunder or
      thereunder.  Except as expressly stated in the Transaction
      Documents, the Disbursement Agent shall not be required to ascertain
      or inquire as to the performance by the SPV or the Collateral Agent
      of any of their respective obligations under this Agreement, any
      other Transaction Document, or any other document or agreement
      contemplated hereby or thereby.  The Disbursement Agent shall not be
      (i) required to initiate or conduct any litigation or collection
      proceeding hereunder or under any other Transaction Document or (ii)
      responsible for any action taken or omitted to be taken by it
      hereunder or in connection herewith or therewith, except for its own
      gross negligence or wilful misconduct.

            (d)   Consultation with Experts, Obtaining Instructions, etc.     
      Whenever in the administration of this Agreement the Disbursement
      Agent shall deem it necessary or desirable that a factual matter be
      proved or established in connection with the Disbursement Agent's
      taking, suffering or omitting to take any action hereunder, such
      matter (unless other evidence in respect thereof is herein
      specifically prescribed) may be deemed to be conclusively proved or
      established by a certificate of the SPV, the Collateral Agent or the
      Lender required to be delivered pursuant to the provisions hereof. 
      The Disbursement Agent may consult with counsel, accountants or
      other experts, and any opinion of such counsel, accountants or other
      experts shall be full authorization and protection in respect of any
      action taken, suffered or omitted by the Disbursement Agent under
      this Agreement in accordance therewith.  The Disbursement Agent
      shall have the right at any time to seek instructions concerning the
      administration of this Agreement from any court of competent
      jurisdiction, or, prior to satisfaction in full of the Secured

a Lender), and FAB, as agent for the Lenders (in such capacity,
together with its successors and assigns, the Agent).

issued by Lime SPV.

Project and that, among other things, additional property is
being pledged to the Lenders as collateral security.

               (viii)  The following new Section 1.9 is added at the

                       Section 1.9  Extension of Maturity Date.  (a) 
               At least 10 but not more than 60 days before each
               June 30, the Borrowers may, by delivering a written
               request to the Agent (each such request being
               irrevocable), request that each Lender extend for
               one year the Maturity Date with respect to such
               Lender's Revolving Line of Credit commitment and
               commitment to issue (or cause to be issued) Letters
               of Credit (such commitments referred to herein
               collectively, with respect to each Lender, as such
               Lender's "Commitment").  The Agent shall, upon its
               receipt of such a request, promptly notify each
               Lender thereof, and request that each Lender
<PAGE>                       -22-<PAGE>
               promptly advise the Agent of its approval or
               rejection of such request.

                       (b)    Upon receipt of such notification from
               the Agent, each Lender may (but shall not be
               required to), in its sole and absolute discretion
               (notwithstanding any covenant or other provision
               contained herein), agree to extend the Maturity
               Date with respect to its Commitment for a period of
               one year, and shall (should it determine to do so),
               no later than 60 days following its receipt of such
               notification, notify the Agent of its approval
               concerning such request.  If any Lender shall not
               so notify the Agent, such Lender shall be deemed
               not to have consented to such request.  The Agent
               shall thereupon provide written notice (the
               "Extension Notice") to the Borrowers and all of the
               Lenders as to the Lenders, if any, that have
               consented to such request.  If, within such 60-day
               period, any Lender has elected not to extend (or
               failed to notify the Agent of its consent to
               extend) its Commitment, then each Lender that has
               agreed to extend the Maturity Date may, in its sole
               and absolute discretion, within ten business days
               after its receipt of the Extension Notice, withdraw
               its previous approval concerning such request.

                       (c)    The Commitment of each Lender that
               agrees to extend the Maturity Date shall be
               extended for a period of one year, commencing on
               the then-scheduled Maturity Date.  If any Lender
               has elected not to extend (or failed to notify the
               Agent of its consent to extend) its Commitment,
               such Lender's Commitment shall terminate
               automatically on the then-scheduled Maturity
               Date, and the Borrowers shall be required to repay
               on such date the outstanding principal amount of
               all Revolving Line of Credit loans, if any, made by
               such Lender, together with accrued interest, fees
               and all other amounts then payable to such Lender
               pursuant to this Agreement; provided, however,
               that the Borrowers may, provided that no Default
               or Event of Default shall then have occurred and
               be continuing, demand that such Lender assign to
               one or more financial institutions designated by
               the Borrowers (a "Replacement Lender"), on terms
               and conditions reasonably acceptable to such
               Lender, all (but not less than all) of such Lender's
               Commitment and the Revolving Line of Credit
               advances owing to it, which assignment shall be
               consummated within 45 days after such Lender
               notifies the 
<PAGE>                       -23-<PAGE>
               Agent of its election not to extend its Commitment
               (or, if such Lender fails to notify the Agent of its
               consent to extend, within 45 days after such
               Lender is deemed to have failed to consent to such
               extension).  The Borrower shall, as a condition to
               the effectiveness of any such assignment, cause
               the replacement of all Letters of Credit issued by
               such Lender with Letters of Credit issued by the
               Replacement Lender.  The Borrowers shall notify
               the Lenders of any proposed Replacement Lender
               no later than ten days prior to the effectiveness
               of any such assignment.  If, prior to the end of
               such 45-day period, any Lender that has agreed to
               extend the Maturity Date notifies the Borrowers
               that any proposed Replacement Lender is not
               acceptable to it, such Lender may withdraw its
               previous approval concerning such extension.

               (b)     Amendment to Article V.  Section 5.1(b)(1) is
        amended by inserting the phrase "and in the Note
        Purchase Agreement" immediately following the phrase
        "the representations and warranties of the Dravo
        Parties set forth herein".

               (c)     Amendments to Article IX.  Article IX shall be
        amended as follows:

               (i)     The first sentence of Section 9.1(a) is
        amended in its entirety to read as follows:

               Lenders agree as between themselves that upon
               receipt of a request for an advance hereunder by
               Borrowers (or either of them), and so long as there
               shall exist no Event of Default or Default, FAB will
               advance 31.88% of such request, PNC will advance
               24.64% of such request, Continental will advance
               28.99% of such request and Prudential will advance
               14.49% of such request (each such percentage
               referred to herein as such Lender's "Percentage";
               provided, however, that in no event shall the
               aggregate principal amount of the Revolving Line
               of Credit loans made hereunder by Lenders exceed
               $75,000,000.00.

               (ii)    Section 9.1 is further amended by adding the
        following new subsections (c), (d) and (e) at the end
        thereof:

                       (c)    Notwithstanding subsections (a) and (b)
               above, in the event that any Lender does not agree
               to provide any funds (to the extent that such
               funds are not otherwise 
<PAGE>                       -24-<PAGE>
               available to be borrowed by the Borrowers from
               such Lender pursuant to this Agreement) for (i) the
               cure of any defaults pursuant to Article 6 of the
               Project Intercreditor Agreement or (ii) the
               purchase price of any assets sold by Lime SPV in
               connection with the exercise by the Lenders of any
               right of first refusal pursuant to Section
               5.03(a)(iv)(2) of the Override Agreement, the
               Lenders that agree to provide such funds (the
               "Funding Lenders") shall advance such funds on a
               pro rata basis, based on the proportion of each
               Funding Lender's Commitment to the aggregate
               amount of the Commitments of the Funding Lenders. 
               So long as no Event of Default shall have occurred
               and be continuing, notwithstanding Section 11.7,
               any amounts of principal prepaid or repaid by the
               Borrowers pursuant to this Agreement shall be
               applied, first, to the repayment of all advances
               made by the Funding Lenders pursuant to clauses
               (i) and (ii) above (on a pro rata basis based on the
               amount of advances made by each of the Funding
               Lenders) and second, to the repayment of all other
               amounts owing to the Lenders hereunder (on a pro
               rata basis in accordance with their respective
               percentages set forth in subsection (a) above), in
               each case otherwise in accordance with this
               Agreement.  Upon the occurrence and during the
               continuance of an Event of Default, any amounts
               of principal prepaid or repaid by the Borrowers or
               otherwise realized pursuant to any Security
               Document shall be applied on a pro rata basis in
               accordance with the percentages of the Lenders
               set forth in subsection (a) above.  Any funds
               provided by a Funding Lender pursuant to clauses
               (i) and (ii) above shall be deemed to be a Revolving
               Line of Credit advance made by such Lender to the
               Borrowers, and the Borrowers shall be obligated to
               repay such advances pursuant to the terms
               hereof.  In furtherance of the foregoing, any
               purchase of assets pursuant to clause (ii) above
               shall be made on behalf of Lime, and Lime shall be
               the legal and beneficial owner of such assets.  

                       (d)    In connection with any advances made
               by the Funding Lenders pursuant to subsection (c)
               above, the Companies shall execute such
               agreements, documents and instruments (including,
               without limitation, additional promissory notes),
               and take such further actions, as any Funding
               Lender may reasonably request.
<PAGE>                       -25-<PAGE>
                       (e)    Notwithstanding anything to the
               contrary contained herein, in order to effect the
               cure of any default pursuant to Article 6 of the
               Project Intercreditor Agreement, the Lenders shall
               have the right (but not the obligation) to advance
               funds on behalf of the Borrowers and to make any
               payments directly to any Persons (other than the
               Borrowers) to the extent necessary to cure such
