Notwithstanding the foregoing, the Company will obtain the Issuer’s approval of the addition of any proposed unit of the Project Facilities not already described in the application for bond financing submitted to the Issuer.

The Issuer and the Company hereby covenant for the benefit of the holders of the Bonds that, notwithstanding any other provision of this Agreement or any other instrument, they will neither make, nor instruct the Trustee to make, any investment or other use of moneys from the proceeds of the Bonds which would cause the Bonds to be arbitrage bonds under Section 148 of the Code and the regulations thereunder, including Section 148(f) which requires generally a rebate payment to the United States of arbitrage profit from investment of the proceeds of the Bonds, to the extent that the same are applicable at the time of such investment or use, and that they will comply with the requirements of such Section and regulations throughout the term of the Bonds.

Section 3.10 Restriction on Use of Proceeds of Bonds. The Company hereby covenants that it shall not use or direct the use of moneys from the proceeds of the Bonds in any way, or take any other action or omit to take any action, which would cause the interest on the Bonds (other than the Bonds held by a “substantial user” of the Project Facilities or by a “related person” as such terms are defined in Section 147(a) of the Code) to be includable in gross income of the owners thereof for federal income tax purposes under the Code as in effect on the date the Bonds are issued.

Concurrently with the delivery of the Bonds, the Issuer will, upon the terms and conditions of this Agreement, lend to the Company by deposit of the proceeds thereof in accordance with the provisions of the Indenture, an amount equal to the aggregate principal amount of the Bonds. To the extent that accrued interest on the Bonds is received by the Issuer upon the sale of the Bonds and is deposited into the Bond Fund established under the Indenture, such accrued interest shall be applied to the first interest payment due on the Bonds with a corresponding credit on the amounts otherwise due under the First Mortgage Bond.

(b) To the extent that on the applicable Purchase Date moneys on deposit in the Remarketing Proceeds Account and the Liquidity Facility Account of the Purchase Fund established under Section 3.03 of the Indenture are insufficient to pay the full purchase price of Bonds to be purchased pursuant to Section 3.01 of the Indenture, the Company shall pay to the Trustee for deposit in the Company Purchase Account of the Purchase Fund established under Section 3.03 of the Indenture amounts sufficient to cover the shortfall.

Section 4.03 The First Mortgage Bond.

occurrence of an event which gives rise to redemption specified in the Indenture and in accordance with the provisions thereof. Upon any such redemption, the Company shall prepay the First Mortgage Bond in full or in part, as and to the extent that all or a portion of the principal amount of the Bonds is then subject to redemption on such redemption date to the extent that such partial redemption will preserve the exclusion from gross income for federal income tax purposes of interest on the Bonds remaining outstanding after such redemption).

Section 4.05 No Defense or Set-Off. The obligations of the Company to make payments required under Section 4.02 hereof and the First Mortgage Bond shall be absolute and unconditional without defense or set-off by reason of any default by the Issuer under this Agreement or under any other agreement between the Company and the Issuer, or for any other reason, including, without limitation, any acts or circumstances that may constitute failure of consideration, destruction of or damage to the Project Facilities, commercial impracticability or frustration of purpose, any loss of the proceeds of the Bonds or on any investment thereof, or failure of the Issuer to perform and observe any agreement, whether express or implied, or any duty, liability or obligation arising out of or connected with this Agreement, it being the intention of the parties that the payments required hereunder will be paid in full when due without any delay or diminution whatsoever.
