(b)    The Company warrants, represents, and certifies to the Issuer that the proceeds of the 2018 Series A Bonds will not be used in any manner that would cause the 2018 Series A Bonds to be “arbitrage bonds” under Code Sections 103(b)(2) and 148 and other applicable sections thereof. To the best knowledge and belief of the Company, there are no facts, estimates, or circumstances that would materially change the foregoing conclusion.

(e)    The Company warrants, represents, and certifies to the Issuer that the proceeds of the 2018 Series A Bonds will be applied and invested in compliance with the current requirements of Code Section 149(g) and that consequently the 2018 Series A Bonds will not be “hedge bonds” under such Code Section 149(g).

(f)    The Company hereby covenants and agrees that it will at all times comply with the provisions of Code Section 148, including Section 148(f) and with Section 6.06 of the Indenture. Specifically, the Company shall carry out, do, and perform all acts stipulated to be performed by the Company pursuant to Section 6.06 of the Indenture.

As set forth in Section 5.1 hereof, it is understood and agreed that this Agreement and all payments made by the Company pursuant to this Agreement (except payments pursuant to Section 5.1(b) and (c) hereof or pursuant to Section 8.2 hereof) are assigned by the Issuer to the Trustee. The Company assents to such assignment and hereby agrees that, as to the Trustee, the Paying Agent, and the Tender Agent, as applicable from time to time, its obligation to make such payments shall be absolute, irrevocable, and unconditional and shall not be subject to cancellation, termination, or abatement or to any defense or any right of set-off, counterclaim, or recoupment arising out of any breach by any party, whether hereunder or otherwise, or out of any indebtedness or liability at any time owing by any party. Except as provided above, the Issuer hereby directs the Company and the Company hereby agrees to pay directly to the Trustee, the Paying Agent, the Bond Registrar, the Tender Agent, and the Issuer, as appropriate, all said payments payable by the Company pursuant to Section 5.1 hereof.

Section 5.3.    Taxes And Other Governmental Charges. The Company agrees to pay during the term of this Agreement, as the same respectively become due, all taxes, assessments, and other governmental charges of any kind whatsoever that may at any time be lawfully assessed, levied, or charged against or with respect to the Project; provided, that with respect to special assessments or other governmental charges that may lawfully be paid in installments over a period of years, the Company shall be obligated to pay only such installments as may have become due

and provided further that nothing herein shall be construed as obligating the Company to pay taxes on any interest or principal on the 2018 Series A Bonds disbursed to the Holders.

The Company may, at its expense and in its own name, in good faith contest any such taxes, assessments, and other governmental charges and, upon any such contest, may permit the taxes, assessments, or other governmental charges so contested to remain unpaid during the period of such contest and any appeal therefrom unless, in the opinion of its counsel, by nonpayment of any such items the security provided pursuant to the provisions of the Indenture will be materially endangered, in which event such taxes, charges for payments in lieu of taxes, assessments, or other governmental charges shall be paid forthwith. The Issuer will cooperate fully with the Company in any such contest. If the Company shall fail to pay any of the foregoing items required by this Section 5.3 to be paid by the Company, the Issuer or the Trustee may (but shall be under no obligation to) pay the same and any amounts so advanced therefor by the Issuer or the Trustee shall become an additional obligation of the Company to the one making the advancement, which amounts, together with interest thereon the Company agrees to pay at a rate which shall be one percent above the lowest minimum lending rate publicly quoted at such time as being charged by any commercial bank which is a member of the New York Clearing House on 90-day commercial loans to its prime commercial borrowers or the maximum rate permitted by law, whichever is lesser, until paid; but no such advancement shall operate to relieve the Company from any default hereunder. The Company may at its expense and in its own name and behalf apply for any tax exemption or exemption from payments in lieu of taxes allowed by the Commonwealth of Kentucky, or any political or taxing subdivision thereof under any existing or future provision of law which grants or may grant any such tax exemption or exemption from payments in lieu of taxes.

Section 5.4.    Obligations Of The Company Unconditional. The obligation of the Company to make the payments pursuant to this Agreement and to make any payments required in respect of the Rebate Fund as provided in Section 6.06 of the Indenture shall be absolute and unconditional.

Nothing contained in this Section 5.4 shall be construed to release the Issuer from the performance of any of the agreements on its part herein contained; and if the Issuer should fail to perform any such agreement on its part, the Company may institute such action against the Issuer as the Company may deem necessary to compel performance so long as such action shall be in accordance with the agreements on the part of the Company contained in the preceding sentence. The Company may, however, at its own cost and expense and in its own name or in the name of the Issuer, prosecute or defend any action or proceeding or take any other action involving third persons which the Company deems

reasonably necessary in order to secure or protect its right of ownership, possession, occupancy, and use of the Project, and in such event the Issuer hereby agrees to cooperate fully with the Company.

Section 5.5.    Rebate Fund. The Company agrees to make all payments to the Trustee and rebate all amounts to the United States of America as are required of it under the Code and the Indenture. The obligation of the Company to make such payments shall remain in effect and be binding upon the Company notwithstanding the release and discharge of the Indenture.

The Company shall have the privilege at its own expense of remodeling the Project or making substitutions, modifications, and improvements to the Project from time to time as it, in its discretion, may deem to be desirable for its uses and purposes, which remodeling, substitutions, modifications, and improvements shall be included under the terms of this Agreement as part of the Project;

provided, however, that the Company shall take no actions which will change or alter the basic nature of the Project as Environmental Facilities.

If, after the acceleration of the maturity of the outstanding 2018 Series A Bonds by the Trustee pursuant to the Indenture, and before any judgment or decree for the appointment of a receiver or for the payment of the moneys due shall have been obtained or entered, the Company shall cause to be deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all 2018 Series A Bonds and the principal of, and premium, if any, on any and all 2018 Series A Bonds which shall have become due otherwise than by reason of such declaration (with interest upon such principal and premium, if any, and overdue installments of interest, at the rate per annum which is one percent above the highest rate borne by any 2018 Series A Bond, until paid), and such amounts as shall be sufficient to cover all expenses of the Trustee in connection with such default, and all defaults under the Indenture and this Agreement, other than nonpayment of principal of 2018 Series A Bonds which shall have become due by said declaration, shall have been remedied, and such Event of Default under the Indenture shall be deemed waived by the Trustee in accordance with Section 9.11 of the Indenture with the consequence that under the Indenture such acceleration is rescinded, then the Company’s default hereunder shall be deemed to have been waived by the Issuer and no further action or consent by the Trustee or the Issuer shall be required. If any agreement or covenant contained in this Agreement should be breached by either party and thereafter waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder.

Section 10.1.    Options To Prepay Loan. The Company shall have, and is hereby granted, options to prepay the Loan in whole and to cancel or terminate this Agreement on any Business Day at any time the Company so elects, if certain events shall have occurred within the 180 days preceding the giving of written notice by the Company to the Trustee of such election, as follows:

(a)    If in the judgment of the Company, unreasonable burdens or excessive liabilities shall have been imposed after the issuance of the 2018 Series A Bonds upon the Company with respect to the Project or the operation thereof, including without limitation federal, state, or other ad valorem, property, income, or other taxes not imposed on the date of this Agreement other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Project;

(b)    If the Project or a portion thereof or other property of the Company in connection with which the Project is used shall have been damaged or destroyed to such an extent so as, in the judgment of the Company, to render the Project or other property of the Company in connection with which the Project is used unsatisfactory to the Company for its intended use and such condition shall continue for a period of six months;

(c)    There shall have occurred condemnation of all or substantially all of the Project or the taking by eminent domain of such use or control of the Project or other property of the Company in connection with which the Project is used so as, in the judgment of the Company, to render the Project or other property of the Company in connection with which the Project is used unsatisfactory to the Company for its intended use;

(d)    If changes, which the Company cannot reasonably control, in the economic availability of materials, supplies, labor, equipment, or other properties or things necessary for the efficient operation of the Ghent Generating Station of the Company shall have occurred which, in the judgment of the Company, render the continued operation of the Ghent Generating Station or any generating unit at such station uneconomical; or changes in circumstances, after the issuance of the 2018 Series A Bonds including but not limited to changes in solid waste disposal requirements, shall have occurred such that the Company shall determine that use of the Project is no longer required or desirable;

(e)    If this Agreement shall become void or unenforceable or impossible of performance by reason of any changes in the Constitution of the Commonwealth of Kentucky or the Constitution of the United States of America or by reason of legislative or administrative action, whether state or federal, or any final decree, judgment, or order of any court or administrative body, whether state or federal; or

(f)    A final order or decree of any court or administrative body after the issuance of the 2018 Series A Bonds shall require the Company to cease a substantial part of its operations at the Ghent Generating Station to such extent that the Company will be prevented from carrying on its normal operations at such location for a period of six months.

In the case of prepayment pursuant to this Section 10.1 (or if any 2018 Series A Bonds be redeemed in whole or in part pursuant to Section 6.1 hereof), the Loan prepayment price shall be a sum sufficient, together with other funds deposited with the Trustee and available for such purpose, to redeem all 2018 Series A Bonds then outstanding (or, in the case any 2018 Series A Bonds are redeemed in part pursuant to Section 6.1 hereof, such portion of the 2018 Series A Bonds then outstanding) under the Indenture at a price equal to 100% of the principal amount thereof plus interest accrued and to accrue to the date of redemption of the 2018 Series A Bonds and to pay all

reasonable and necessary fees and expenses of the Trustee and any Paying Agents and all other liabilities of the Company accrued and to accrue hereunder to the date of redemption of the 2018 Series A Bonds. In order to exercise any option to prepay the Loan and to cancel or terminate this Agreement by reason of the occurrence of any of the events mentioned in (a) through (f) above, the Company is required to give written notice to the Trustee of its election to prepay the Loan within 180 days of the occurrence of any of the events mentioned in (a) through (f) above.

Section 10.2.    Additional Option To Prepay Loan. The Company shall have, and is hereby granted, further options, to the extent that the 2018 Series A Bonds are, from time to time, subject to optional redemption, during any period of optional redemption, to prepay all, or any portion, of the relevant and applicable Loan payments due or to become due hereunder by depositing with the Trustee moneys sufficient to pay, together with other funds deposited with the Trustee and available for such purpose, the principal of and applicable premium, if any, and accrued interest, through the date of redemption (which must be a Business Day), on all or any portion of the 2018 Series A Bonds then outstanding under the Indenture and, upon depositing with the Trustee moneys sufficient to pay the principal, applicable premium, if any, and accrued interest, through the date of redemption, on all 2018 Series A Bonds then outstanding under the Indenture, as well as all reasonable and necessary expenses of the Trustee and any Paying Agents and all other liabilities of the Company accrued and to accrue hereunder, to cancel or terminate the term of this Agreement.

Section 10.3.    Obligations To Prepay Loan.

(a)    Mandatory Redemption Upon Determination Of Taxability. The Company shall be obligated to prepay the entire Loan or any part thereof, as provided below, before the required full payment of the 2018 Series A Bonds (or before making provision for payment thereof in accordance with the Indenture) on the 180^th day (or such earlier date as may be designated by the Company), which, in every case, must be a Business Day, upon the occurrence of a Determination of Taxability. The Issuer and the Company shall take all actions required to mandatorily redeem the 2018 Series A Bonds at the cost of the Company upon the terms specified in this Agreement and in ARTICLE IV of the Indenture following the occurrence of a Determination of Taxability, including prepaying appropriate amounts due on the 2018 Series A Bonds in order to effect such redemption. The 2018 Series A Bonds shall be redeemed by the Issuer, in whole, or in such part as described below, at a redemption price equal to 100% of the principal amount thereof, without redemption premium, plus accrued interest, if any, to the redemption date, within 180 days following a Determination of Taxability. For purposes of this Section 10.3, a “Determination of Taxability” shall mean the receipt by the Trustee of written notice from a current or former registered owner of a 2018 Series A Bond or from the Company or the Issuer of: (1) the issuance of a published or private ruling or a technical advice memorandum by the Internal Revenue Service in which the Company participated or has been given the opportunity to participate, and which ruling or memorandum the Company, in its discretion, does not contest or from which no further right of administrative or judicial review or appeal exists; or (2) a final determination from which no further right of appeal exists of any court of competent jurisdiction in the United States in a proceeding in which the Company has participated or has been a party, or has been given the opportunity to participate or be a party, in each case, to the effect that as a result of a failure by the Company to perform or observe any covenant or agreement or the inaccuracy of any representation contained

in this Agreement or any other agreement or certificate delivered in connection with the 2018 Series A Bonds, the interest on the 2018 Series A Bonds is included in the gross income of the owners thereof for federal income tax purposes, other than with respect to a person who is a “substantial user” or a “related person” of a substantial user within the meaning of Code Section 147; provided, however, that no such Determination of Taxability shall be considered to exist as a result of the Trustee receiving notice from a current or former registered owner of a 2018 Series A Bond or from the Issuer unless (i) the Issuer or the registered owner or former registered owner of the 2018 Series A Bond involved in such proceeding or action (A) gives the Company and the Trustee prompt notice of the commencement thereof; and (B) (if the Company agrees to pay all expenses in connection therewith) offers the Company the opportunity to control unconditionally the defense thereof, and (ii) either (A) the Company does not agree within 30 days of receipt of such offer to pay such expenses and liabilities and to control such defense; or (B) the Company shall exhaust or choose not to exhaust all available proceedings for the contest, review, appeal, or rehearing of such decree, judgment, or action which the Company determines to be appropriate. No Determination of Taxability described above will result from the inclusion of interest on any 2018 Series A Bond in the computation of minimum or indirect taxes. All of the 2018 Series A Bonds shall be redeemed upon a Determination of Taxability as described above unless, in the opinion of Bond Counsel, redemption of a portion of the 2018 Series A Bonds of one or more series or one or more maturities would have the result that interest payable on the remaining 2018 Series A Bonds outstanding after the redemption would not be so included in any such gross income.

If the Issuer, the Company, or the Trustee has been put on notice or becomes aware of the existence or pendency of any inquiry, audit, or other proceedings relating to the 2018 Series A Bonds being conducted by the Internal Revenue Service, the party so put on notice shall give immediate written notice to the other parties of such matters.

Promptly upon learning of the occurrence of a Determination of Taxability (whether or not the same is being contested), or any of the events described in this Section 10.3(a), the Company shall give notice thereof to the Trustee and the Issuer.

(b)    In the case of the mandatory obligation of the Company to prepay the Loan or any part thereof after the occurrence of a Determination of Taxability, pursuant to Section 10.3(a) hereof, the Company shall be obligated to prepay such Loan or such part thereof not later than 180 days after any such final determination as specified in Section 10.3(a) hereof and to provide to the Trustee for deposit in the Bond Fund an amount sufficient, together with other funds deposited with the Trustee and available for such purpose, to redeem such 2018 Series A Bonds at the price of 100% of the principal amount thereof in accordance with Section 5.1 hereof plus interest accrued and to accrue to the date of redemption of the 2018 Series A Bonds and to pay all reasonable and necessary fees and expenses of the Trustee and any paying agents and all other liabilities of the Company accrued and to accrue hereunder to the date of redemption of the 2018 Series A Bonds.

(c)    If a Determination of Taxability occurs when all or any portion of the 2018 Series A Bonds are owned by any Purchaser, the Company hereby agrees to pay to such Purchaser, in addition to the redemption price of the 2018 Series A Bonds owned by such Purchaser, the following additional amounts:

(1)    an additional amount equal to the difference between (A) the amount of interest paid on the 2018 Series A Bonds during the Taxable Period and (B) the amount of interest that would have been paid on the 2018 Series A Bonds during the Taxable Period had the 2018 Series A Bonds borne interest at the Taxable Rate; and

(2)    an amount equal to any interest, penalties on overdue interest, and additions to tax (as referred to in Subchapter A of Chapter 68 of the Code) owed by such Purchaser as a result of an occurrence of a Determination of Taxability.

R. W. Beck, Inc. (R. W. Beck) was retained by Lehman Brothers, Inc. (the Client) and Kentucky Utilities Company (the Sponsor); pursuant to a Professional Services Agreement (the PSA) dated April 27, 2007. Under the PSA, R. W. Beck undertook an independent engineering review of the Sponsor’s proposed solid waste collection, storage, treatment, and disposal facilities, for the collection, control and disposal of solid wastes created at the Ghent Generating Station Unit 1 (the Project), which is now under construction, by operation of flue gas desulphurization (FGD) facilities serving the Unit 1 generating unit in order to provide an analysis regarding the type or classification of equipment and systems within the Project which qualify for the solid waste disposal facilities designation for tax exempt status.

The Project will be constructed at the existing Ghent Generating Station located in Carroll County, Kentucky. The Sponsor reported to R. W. Beck that it intends to construct the Project through Fluor Corporation (or a subsidiary or an affiliate thereto) (Fluor) and that major equipment such as the absorber, reaction tank and related facilities will be provided by Babcock Power Environmental, Inc. (BPEI). The Sponsor has provided R. W. Beck with capital cost estimates for certain pieces of the major equipment, as more fully discussed herein. Furthermore, the Sponsor reported that the Project design is the same as previous projects related to the Ghent Plant Unit 3 FGD system (Unit 3 Scrubber) and Unit 4 FGD system (Unit 4 Scrubber) and advised that certain information previously provided to R.W. Beck related to the Unit 3 Scrubber be used as a basis from which to perform its analysis with respect to capital costs required to compute the costs of the Project.

The Ghent Generating Station is a coal fired steam electric generating station located in Carroll County, Kentucky. Air emission control regulations require removal of particulates and sulfur dioxide (SO2) from the flue gas exhaust emissions and solid waste disposal regulations require the disposal of combustion by-products including FGD-generated waste slurry (calcium sulfite, also referred to as lime mud sludge).

To comply with air pollution control regulations, the use of FGD facilities is required for removal of SO2 from the flue gas exhaust of the generating units at the Ghent Generating Station. Operation of FGD facilities using calcium carbonate (limestone reagent) for desulfurization produces a solid waste in the form of calcium sulfite, which is oxidized to produce impure calcium sulfate.

The large quantity of FGD-produced solid sludge wastes requires large scale solid waste sludge handling and disposal facilities. The disposal costs for collection, storage, treatment, handling, and final disposal of such solid wastes are significant and the Sponsor has an indefinite responsibility to maintain the solid waste storage facilities.

FGD-produced sludge wastes are solid wastes which will be generated by Ghent Generating Station Unit 1. These wastes have no use and no value in their original form and are required to

be disposed of in a solid waste disposal facility or processed further to produce a material that may be saleable.

The project will consist of the construction and installation of a complete new FGD system and associated equipment. The Project includes all necessary equipment for FGD system solid waste sludge collection, storage, treatment, and handling. Solid waste sludge from the Project will be conveyed to the existing sludge waste (impure gypsum) settling pond.

In the FGD system, SO2 is removed from the flue gas by reacting it with calcium carbonate (limestone). The calcium carbonate is mixed with water (a carrier) to create a slurry that can be sprayed into the flue gas within the FGD absorber vessel. The initial step of the process chemically substitutes SO2 for the carbonate in limestone to create a solid sludge waste, primarily calcium sulfite, a sludge which must be removed from the reagent solution circulating through the FGD system. Calcium sulfite is useless, unused, unwanted or discarded solid waste material and has no market or other value at the place where it is located.

Further treatment of the solid waste with the introduction of oxygen (forced oxidation) promotes the dewatering and handling characteristics of the solid waste by reacting oxygen with the solid waste calcium sulfite and creating imperfect calcium sulfate.

This further treatment of the solid waste enables the waste by-product to be dewatered more readily and to be disposed of more efficiently.

The calcium sulfate solids (impure gypsum) that are produced after forced oxidation are suspended in water and will settle out if left undisturbed. However, for efficient operation, water is required as a means of transport to solid waste disposal facilities constituting landfills and solid waste dumps. This is the current practice for the Ghent Generating Station where water, as a carrier, transports the impure waste gypsum to an on-site settling pond. This same method of operation is planned and is being implemented for the Project. Transfer pumps and piping transport the solid waste (impure gypsum) to on-site settling sludge disposal ponds.

The FGD system includes equipment to clean flue gas of SO2 generated by the combustion of coal. The cleaning process in turn produces the calcium sulfite, which itself is contaminated by inert particulates and unreacted limestone. Additional solid waste treatment of the calcium sulfite produces an impure gypsum material, which, although more easily transported to waste disposal dumps, is useless, unwanted and discarded solid waste having no market or other value at the place where it is located. Further cleaning, dewatering, processing and purification would be required to convert the impure gypsum into a form which has any commercial value or uses.

Additionally, unreacted limestone is recirculated through the absorber vessel to convert the limestone into calcium sulfite, a solid waste.

According to Treasury Regulation Section 1.103-8(f), a solid waste disposal facility means “... any property or portion thereof used for the collection, storage, treatment, utilization, processing, or final disposal of solid waste...A facility which disposes of solid waste by reconstituting, converting, or otherwise recycling it into material which is not waste shall also qualify as a solid waste disposal facility if solid waste ... constitutes at least 65 percent, by weight or volume, of the total materials introduced into the recycling process ... Solid waste is ... property which is useless, unused, unwanted, or discarded solid material which has no market or other value at the place where it is located.” The Project includes solid waste disposal facilities and does not function as a recycling facility.

The solid wastes produced and handled by the Project will primarily consist of calcium sulfite and impure solid waste calcium sulfate by-product generated by the FGD system. The Project collects, stores, handles and treats the solid wastes generated by the FGD system for disposal in a solid waste landfill. Such solid wastes have no market or other value at the place where they are located because: (i) no person is willing to purchase the non-commercial grade impure gypsum on-site at any price; and (ii) the transportation cost to market exceeds the value, if any, of the non-commercial grade impure gypsum at the market.

Impure contaminated gypsum from the Project will be transported to a holding tank and then pumped to a waste landfill and dump. At present, Synthetic Materials Company is allowed to mine, without purchase, the unwanted material from the pond and waste landfill and dump and process it in an attempt to produce a commercial grade product. Solid waste that cannot be processed into a commercial grade product is returned to the waste landfill and dump.

This Project has both solid waste disposal-related functions and non-solid waste-related functions. Therefore, a methodology was established to separate and allocate the Project’s total costs between the costs related to solid waste disposal functions, which are tax-exempt (Qualifying Costs), and any costs related to any other function, which are not tax-exempt (Non-Qualifying Costs). The Project components were separated into three categories as follows:

As part of R. W. Beck’s methodology, we reviewed the design concept of the Project FGD system, identified those parts of the system that collect, store, handle, and treat the calcium sulfite and impure calcium sulfate wastes, reviewed costs for the various parts of the system provided by the Sponsor and categorized those costs as qualified/non qualified for tax exempt financing purposes using our professional judgment to identify those portions of the costs that are associated with solid waste collection, storage, treatment, and disposal. Our professional judgment in allocating those costs associated with waste collection, storage, treatment, and disposal as qualified costs is based on the incremental costs associated with the design, procurement and installation of the proposed system to collect, store, treat, and dispose of the wastes as compared to generation and FGD facilities not so equipped. Important design variables such as liquid to gas ratios and solid waste concentrations of the various streams were used to allocate costs as Qualifying Costs for tax-exempt financing purposes.

Exhibit 1 also includes additional estimated costs provided to us by the Sponsor associated with the installation of the FGD scrubber but not directly included as part of the BPEI costs discussed above. In general, much of the cost information provided is the total for labor only or a total including material, equipment and labor associated with the Fluor scope.

Following is a description of the Project components and the allocation of the component costs between Qualifying and Non-Qualifying Costs.

The Project FGD Scrubber will consist of a Stebbins scrubber tower, a reactant slurry recirculation system and oxidation air blowers. The scrubber tower will be composed of a liquid holding area (the reaction tank) underneath a space allowing for vertical air and spray slurry countercurrent flow (the absorber vessel). Flue gas enters the bottom of the absorber vessel, passes through a mist eliminator at the top of the absorber vessel and is ducted to a stack for discharge to the atmosphere. Recirculation pumps will recirculate the slurry primarily consisting of limestone, calcium sulfite, calcium sulfate and inert materials from the reaction tank to a spray distribution system at the top of the absorber vessel. The recirculating waste slurry will fall into the reaction tank located at the bottom of the absorber tower. In this stage, the calcium carbonate in the limestone slurry will

react with water and SO2 in the flue gas to produce calcium sulfite, while oxygen exchanged between the flue gas and the liquid droplets will promote some oxidation of calcium sulfite to calcium sulfate.

The reaction tank is designed to hold an adequate liquid volume to ensure efficient usage of limestone and to provide adequate residence time for complete oxidation of calcium sulfite to impure calcium sulfate (impure gypsum). Included as part of the reaction tank will be a fixed air sparger system supplied by the oxidation air blowers, which will be supplied to introduce large quantities of air to maximize the efficiency of the oxidation of calcium sulfite to impure calcium sulfate (impure gypsum). The reaction tank will be the primary vessel in the process to convert calcium sulfite waste by-product into impure calcium sulfate for efficiency in movement and disposal of such solid wastes.

The principal purpose of the scrubber tower is to remove SO2 from the flue gas. However, the costs associated with a portion of the absorber vessel and recirculation loop and all of the absorber reaction tank and oxidation air blowers are included as being Qualifying Costs because they are directly associated with collecting and handling the solid waste (impure gypsum) sludge.

Water acts as the medium and transport mechanism for the recirculation of calcium carbonate and the calcium sulfite waste by-product. Due to the additional pumping demands associated with the oxidation of calcium sulfite, 67.5 percent of the recirculation loop is included as a Qualifying Cost.

The absorber vessel serves a dual function as an air pollution control function associated with the removal of SO2 from the flue gas, which creates calcium sulfite solid wastes, and a simultaneous solid waste collection, handling and disposal function associated with recirculating all of the solid wastes to better utilize the calcium carbonate and to enhance the oxidation of calcium sulfite into calcium sulfate (impure gypsum). The increased recirculation of 67.5 percent is also applied to the absorber vessel and is included as a Qualifying Cost. The Sponsor reports that all of the proceeds of the 2007 Series A Bonds will be applied to the financing of solid waste collection, handling and disposal facilities. As such, no 2007 Series A Bond proceeds will be used to finance any air pollution facilities.

The remaining conversion of calcium sulfite to calcium sulfate takes place in the absorber reaction tank, which is the primary step in the conversion process that converts calcium sulfite waste to calcium sulfate.

In addition to those costs associated with FGD scrubber equipment and materials, certain additional costs are incurred by the Sponsor in relation to the FGD scrubber auxiliary power and structural foundation. The auxiliary power and structural foundation provide support to the air pollution control and solid waste disposal functions of the FGD scrubber. As such, each cost must be proportioned to determine the associated Qualifying Costs. Noting that certain Project costs have not been presented in this report, we have conservatively estimated (as discussed in Table 2-2) that 29.5 percent of the total cost of the Project are Qualifying Costs. This percentage has been applied to the auxiliary power and structural foundation costs to determine the associated Qualifying Costs.

Fluor and Sponsor labor and construction costs were not provided, but certain installation and craft labor costs were provided. Specifically, costs estimates were provided for craft startup support and for the installation of the oxidation air compressors, FGD system recirculation loop pumps and piping. Labor costs were also included as part of the total costs provided for the FGD system structure and foundation, FGD system auxiliary power systems, and the sludge transfer piping and pumps.

Due to the scope of this Report and the limited need to identify additional Qualifying Costs, certain potential and additional Qualifying Costs have not been identified, reviewed or analyzed as part of this analysis.

Set forth below are the principal opinions R. W. Beck has reached after review of the Project. For a complete understanding of the estimates, assumptions and calculations upon which these opinions are based, the Report should be read in its entirety. On the basis of our reviews, analyses and investigations of the Project, and the assumptions set forth in this Report, we are of the opinion that:
