PRELIMINARY STATEMENT

Reference is hereby made to the Bond Trust Indenture (the “Bond Indenture”) dated as of October 1, 2007 between the Issuer and Wells Fargo Bank, National Association, as bond trustee (the “Bond Trustee”), relating to the hereinafter described Series 2007A Bonds, as the same may be supplemented and amended from time to time for definitions of various terms used herein.

The Borrower desires to obtain a portion of the moneys which will be used, together with certain other funds, to (i) pay the cost of acquisition, construction and equipping of improvements and additions to the Facility (the “Project”), including reimbursement to the Borrower of certain moneys previously spent with respect to the Project, (ii) fund a debt service reserve, (iii) to find capitalized interest, and (iv) pay certain expenses incurred in connection with the issuance of the Series 2007A Bonds, all as permitted under the Act.

Pursuant to the Bond Indenture, the Issuer will pledge and assign certain of its rights under this Loan Agreement as part of the security for the Series 2007A Bonds.

ARTICLE III
PAYMENT OF SERIES 2007A BONDS;
APPLICATION OF PROCEEDS; COMPLETION OF PROJECT

Section 3.1 Loan and Application of the Proceeds of Series 2007A Bonds. The Issuer hereby lends all of the proceeds of the Series 2007A Bonds in connection with the original issuance and sale of the Series 2007A Bonds to the Borrower upon the terms and conditions set forth herein. The Borrower agrees that the proceeds of the Series 2007A Bonds being lent to the Borrower shall be deposited with the Bond Trustee and applied as provided in the Bond

Indenture. The Borrower shall have no right to use such proceeds other than pursuant to the terms of the Bond Indenture and may not use such proceeds as general funds.

Section 3.2 Payment of Series 2007A Bonds. The Borrower agrees that the principal of, premium, if any, and the interest on the Series 2007A Bonds shall be made payable in accordance with the provisions of the Bond Indenture and this Loan Agreement. The Borrower further agrees that this Loan Agreement and payments to be made hereunder and thereunder (excluding Unassigned Rights) shall be assigned and pledged to the Bond Trustee to secure the payment of the Series 2007A Bonds. In addition, the Borrower agrees that all amounts due under the Loan Agreement shall be secured by, and payable from the proceeds of enforcement of the Bond Collateral Documents. The foregoing notwithstanding, the Borrower agrees that the moneys and securities, if any, on deposit in the Rebate Fund are not part of the trust estate and are not available to make payments of principal and interest on the Series 2007A Bonds.

Section 3.3 Right of Bond Trustee to Enforce this Loan Agreement. The Borrower agrees that this Loan Agreement and all of the rights, interests, powers, privileges and benefits accruing to or vested in the Issuer under this Loan Agreement may be protected and enforced in conformity with the Bond Indenture and may be thereby assigned by the Issuer to the Bond Trustee (except Unassigned Rights) as security for the Series 2007A Bonds and may be exercised, protected and enforced for or on behalf of the Bondholders in conformity with the provisions of this Loan Agreement and the Bond Indenture.

Section 3.4 Investment of Funds; Arbitrage; Tax Exemption Agreement. The Borrower covenants and agrees that moneys on deposit in any funds under the Bond Indenture shall at all times be invested by the Bond Trustee pursuant to the Borrower’s direction and that the Borrower will take all actions necessary, including without limitation providing the Bond Trustee with all necessary directions, to assure that such moneys are continuously invested in accordance with the provisions of the Bond Indenture and the Tax Exemption Agreement. The Borrower further covenants and agrees that it will not take any action or fail to take any action, including without limitation any action with respect to the investment of the proceeds of any Series 2007A Bonds (regardless of the source or whether or not held under the Bond Indenture), with respect to any other moneys or securities deposited with the Bond Trustee pursuant to the Bond Indenture or with the Accounts Bank pursuant to the Accounts Agreement in the Bond Proceeds Sub-account, with respect to the payments derived from the Loan Agreement, or with respect to any actions or payments required under the Tax Exemption Agreement which may result in the Series 2007A Bonds constituting “arbitrage bonds” within the meaning of such term as used in Section 148 of the Code. The Borrower covenants that neither it nor any related person, as defined in Sections 144(a)(3) and 147(a) of the Code, shall, pursuant to an arrangement, formal or informal, purchase obligations of the Issuer in an amount related to the amount of the Series 2007A Bonds delivered in connection with the transaction contemplated hereby.

Section 3.5 Completion of Project. The Borrower agrees to complete the acquisition, construction and equipping of the Project substantially in accordance with the plans and specifications on file with the Borrower, and to undertake and complete the Project with due diligence. In the event moneys in the Project Fund or the Bond Proceeds Sub-account available for payment of the Costs of the Project are not sufficient to pay Costs of the Project in full, the

Borrower shall cause the Project to be completed and shall pay from other funds of the Borrower that portion of the Costs of the Project in excess of the moneys available therefor in the Project Fund and the Bond Proceeds Sub-account. The Issuer does not make any warranty, either express or implied, that the moneys which will be deposited into the Project Fund will be sufficient to pay all the Costs of the Project.

Section 3.6 Plans and Specifications. The plans and specifications for the Project are on file with the Borrower. The Borrower may revise the plans and specifications at any time and from time to time prior to the completion of the Project provided that no such change shall render inaccurate any of the representations of the Borrower contained in this Loan Agreement or in the Tax Exemption Agreement. No revision to the plans and specifications shall be made which would cause the Costs of the Project to exceed the amounts available in the Project Fund and the Bond Proceeds Sub-account, or otherwise available to the Borrower, to pay such Costs. No revisions to the plans and specifications for the Project will be made which would affect the nature or purpose of the Project or any component thereof, unless the Borrower shall have obtained an opinion of Bond Counsel that such revision will not impair the exclusion from federal income taxation of the interest on the Series 2007A Bonds.

Section 3.7 Records. The Borrower will maintain such records in connection with the acquisition, construction and equipping of the Project as are required to permit ready identification of the Project and the items of Project Costs.

Section 3.8 Operation of Project. So long as the Borrower owns the Project and the Series 2007A Bonds are outstanding, the Project will be operated as a project as contemplated by the Act and as Solid Waste Disposal Facilities as contemplated by Section 142(a)(6) of the Code. To the extent that such definitions are amended after the date of this Loan Agreement, the Borrower will use its reasonable best efforts to operate the Project in accordance with such amendments or changes if, or to the extent, required to maintain the validity or tax exempt status of the Series 2007A Bonds; provided, however, that the Borrower’s failure to operate the Project in such manner will not, in and of itself, constitute a default under this Agreement.

ARTICLE IV
PAYMENTS, FUND DEPOSITS,
PREPAYMENTS AND OTHER PAYMENTS

Section 4.1 Payment of Principal, Premium and Interest. The Borrower will duly and punctually pay all loan repayments and other amounts payable under this Loan Agreement at the dates and the places and in the manner provided in this Loan Agreement according to the true intent and meaning hereof. Notwithstanding any schedule of payments set forth herein, the Borrower agrees to make payments hereunder, and to be liable therefor, at the times and in the amounts (including principal and interest) equal to the amounts which are equal to the principal of, premium, if any, and interest due on the Series 2007A Bonds and the Borrower agrees to make payments equal to the amount due on the Series 2007A Bonds from time to time outstanding, whether as regularly scheduled interest or principal payments, at maturity, upon acceleration or otherwise; provided, however, that the Borrower may be entitled to certain credits on such payments as permitted under Section 4.3 hereof.

(a) Interest: On or before December 31, 2007 (or on the next preceding Business Day if such day is not a Business Day), an amount which, after taking into account the amount available for deposit in the Interest Fund representing capitalized interest to be transferred from the Project Fund to the Interest Fund as described in Section 403 of the Indenture, will be sufficient to pay the interest to become due on the Series 2007A Bonds on January 1, 2008, and on or before each Quarterly Payment Date thereafter (or on the next preceding Business Day if such Quarterly Payment Date is not a Business Day), after taking into account said available amount of capitalized interest, an amount which is not less than one-half (1/2) of the amount of interest to become due on the next succeeding Interest Payment Date of the Series 2007A Bonds; provided, however, that the Borrower may be entitled to certain credits on such payments as permitted under Section 4.3 hereof.

(b) Principal: On or before each Quarterly Payment Date (or on the next preceding Business Day if such Quarterly Payment Date is not a Business Day) commencing March 31, 2015, an amount which is not less than one-fourth (1/4) of the amount of principal to become due on the next succeeding January 1 principal payment date of the Series 2007A Bonds (whether upon maturity or as a result of a Mandatory Sinking Fund Redemption); provided, however, that the Borrower may be entitled to certain credits on such payments as permitted under Section 4.3 hereof.

(c) Commencing as of the first day of the month following any month in which (i) the balance in the Debt Service Reserve Fund is less than the Debt Service Reserve Requirement, (ii) a transfer is made from the Debt Service Reserve Fund to the Interest Fund and/or the Bond Sinking Fund to cure a deficiency therein, or (iii) a draw is made on a surety bond, insurance policy or letter of credit on deposit in the Debt Service Reserve Fund to cure a deficiency in the Interest Fund and/or the Bond Sinking Fund, the amount necessary to restore, in one monthly deposit, if such deficiency is a result of a valuation loss pursuant to Section 405 of the Bond Indenture, and otherwise in twelve equal monthly deposits, the Debt Service Reserve Requirement (or if a draw has been made on a surety bond, insurance policy or letter of credit on deposit in the Debt Service Reserve Fund, to reinstate the maximum limits of such surety bond, insurance policy or letter of credit within the time and in the manner required by the document providing for such surety bond, insurance policy or letter of credit).

Section 4.3 Credits on Loan Repayments. Notwithstanding any provision contained in this Loan Agreement or in the Bond Indenture to the contrary:

(a) any moneys deposited with the Bond Trustee by the Borrower or on behalf of the Borrower by any Affiliate, for the payment of principal of, premium, if any, or interest on, the Series 2007A Bonds or for payment of other amounts due under this Loan Agreement, shall be credited against the obligation of the Borrower to make such payment under this Loan Agreement as the same becomes due; and

(b) the principal amount of Series 2007A Bonds of any maturity delivered by the Borrower to the Bond Trustee, or purchased by the Bond Trustee upon direction of the Borrower and cancelled, shall be credited against the obligation of the Borrower to make a loan repayment (including installment payments corresponding to mandatory sinking fund payments on such Series 2007A Bonds) related to such maturity of Series 2007A Bonds so delivered or purchased to the extent directed by the Borrower; provided, however, that deposit or purchase of a Series 2007A Bond of one maturity may not be credited against a loan repayment which would be used, in the normal course, to retire a Series 2007A Bond of another maturity.

Section 4.4 Mandatory Prepayment Upon a Determination of Taxability. If a final action or decree constituting a Determination of Taxability occurs and the Bond Trustee receives notice thereof, the Bond Trustee shall request, and the Borrower shall pay all amounts due under this Loan Agreement, including without limitation all principal of and accrued interest on the Series 2007A Bonds to the date fixed by the Bond Trustee for redemption of all Series 2007A Bonds pursuant to a mandatory redemption for a Determination of Taxability pursuant to the Bond Indenture. The Bond Trustee shall give notice of redemption for the first redemption date for which notice can be given upon notice of the Determination of Taxability.

Section 4.5 Optional Prepayment. The Borrower shall be permitted at its option to prepay the amounts due under this Loan Agreement for the payment of principal of and redemption premium, if any, and interest on, the Series 2007A Bonds to the extent and in the manner permitted or required by the Bond Indenture for the optional prepayment of the Series 2007A Bonds. Such prepayments shall be made by paying to the Bond Trustee an amount sufficient to redeem (when redeemable) all or a part of the Series 2007A Bonds at the redemption prices specified therefor in the Bond Indenture. No other such prepayment shall be permitted except that other amounts required hereunder as additional payments may be prepaid.

Section 4.6 Notice of Prepayment. The Borrower shall give the Bond Trustee not less than 60 days prior written notice of any optional prepayment, which notice shall designate the date of prepayment and the amount thereof and direct the redemption of Series 2007A Bonds of the maturities and in the amounts to be prepaid. Such notice may be withdrawn by the Borrower at any time prior to delivery of the Written Request of the Borrower to the Bond Trustee described in Section 5.1 of the Bond Indenture.

Section 4.7 Extraordinary Optional Prepayment from Net Proceeds of Insurance or Condemnation. The Borrower shall have the right to prepay the loan repayments due hereunder from the Net Proceeds of insurance, condemnation or sale consummated under threat of condemnation by giving the Bond Trustee direction to apply such Net Proceeds. In such event the Bond Trustee shall apply such Net Proceeds promptly to prepay the loan repayments due hereunder and the Series 2007A Bonds, without premium, plus accrued and unpaid interest thereon to the date of prepayment. Prepayments under this Section shall be credited against the mandatory installment payments to be made hereunder corresponding to the related payments to be applied to the payment of the Series 2007A Bonds. Notwithstanding partial prepayment made pursuant to this Section, the Borrower is obligated to make the mandatory principal payments hereunder pursuant to Section 4.2(b) hereof to the extent any portion of the Series 2007A Bonds remains Outstanding.

Section 4.8 Mandatory Prepayment on the Completion Date. The Bond Trustee shall give notice to the Borrower of all amounts on deposit in the Project Fund and the Bond Proceeds Sub-account on the date of Substantial Completion not required for the payment of remaining Costs of the Project and the Borrower agrees to the mandatory use of such funds by the Bond Trustee to prepay in part the principal amount due under this Loan Agreement to redeem Series 2007A Bonds as required under the Bond Indenture upon payment of amounts, if any, in the Bond Proceeds Sub-account to the Bond Trustee..

Section 4.9 Effect of Partial Prepayment. Upon any partial prepayment hereunder relating to the debt service on the Series 2007A Bonds, each installment of interest which shall thereafter be payable hereunder shall be reduced, taking into account the interest rate or rates on the Series 2007A Bonds remaining outstanding after the redemption of Series 2007A Bonds from the proceeds of such partial prepayment and after the purchase and delivery and cancellation of Series 2007A Bonds described in Section 4.3(c) hereof, so that the interest remaining payable on hereunder shall be sufficient to pay the interest on such outstanding Series 2007A Bonds when due.

Section 4.10 Additional Payments. The Borrower agrees to pay directly all costs incurred by or on behalf of the Issuer, the Bond Trustee or the Borrower in connection with or incident to the issuance and sale of the Series 2007A Bonds which exceed the amount on deposit in the Expense Fund described in Section 3.2 of the Bond Indenture.

The Borrower also agrees to pay the following items to the following persons as additional payments under this Loan Agreement:

(2) to the Issuer, upon demand, an amount equal to all expenses incurred by the Issuer in relation to the Series 2007A Bonds which are not otherwise required to be paid by the Borrower under the terms of this Loan Agreement; and

(3) to the Issuer or the Bond Trustee, as the case may be, the amount of all advances of funds made by either of them under the provisions of this Loan Agreement or an amount equal to all advances of funds made by either of them under the Bond Indenture, with interest thereon at the Bond Trustee’s announced prime rate per annum from the date of each such advance.

Section 4.11 Borrower’s Obligations Unconditional. The Issuer and the Borrower agree that the Borrower shall bear all risk of damage to or destruction in whole or in part of the Facility, its other Property or any part thereof, including without limitation any loss, complete or partial, or interruption in the use, occupancy or operation of the Facilities or its other Property, or any manner or thing which for any reason interferes with, prevents or renders burdensome, the

use or occupancy of the Facilities or its other Property or the compliance by the Borrower with any of the terms of this Loan Agreement. In furtherance of the foregoing, but without limiting any of the other provisions of this Loan Agreement, the Borrower agrees that its obligations to pay the principal of and interest hereunder and on the Series 2007A Bonds and to pay the other sums herein provided for and to perform and observe its other agreements contained herein shall be absolute and unconditional and that the Borrower shall not be entitled to any abatement or diminution thereof or to any termination of this Loan Agreement or the Series 2007A Bonds for any reason whatsoever.
