Any such revision of redemption periods or redemption prices shall not be considered an amendment of or supplement to this supplemental indenture and shall not require the consent of any other person or entity. (b) in whole (or in part if, in the opinion of nationally recognized bond counsel, such partial redemption will preserve the exclusion from gross income for Federal income tax purposes of interest on the 2004 Series C Authority Bonds remaining outstanding after such redemption) at any time at 100% of the principal amount thereof to be redeemed, plus interest accrued to the redemption date, within 180 days after a "final determination" (i.e., the issuance of a published or private ruling or technical advice) of the Internal Revenue Service or a judicial decision in a proceeding by any court of competent jurisdiction in the United States (from which ruling, advice or decision no further right of appeal exists), in all cases in which the Company has participated or been a party or has been given an opportunity to participate and has failed to do so (no such decree or judgment by any court or action by the Internal Revenue Service to be considered final unless the owner of the 2004 Series C Authority Bonds involved in such proceeding or action has given the Company and the Authority Trustee prompt written notice of the commencement thereof and offered the Company, at the Company's expense, the opportunity to control the defense thereof) that, as a result of a failure by the Company to observe any covenant, agreement, representation or warranty in the Agreement, the interest payable on the 2004 Series C Authority Bonds is includable in the gross income for Federal income tax purposes of the holder thereof, other than a "substantial user" of the Project or a "related person" as provided in Section 147 (a) of the Internal Revenue Code of 1986, as amended, and the applicable regulations thereunder. <Page> 8 (c) in whole at 100% of the principal amount thereof whenever the Company receives from the Authority Trustee a copy of a written demand sent to the Trustee stating that the principal of all outstanding 2004 Series C Authority Bonds has been declared to be immediately due and payable because of an Event of Default under the Authority Indenture. In such case, redemption of the Bonds of the Pollution Control Series AE shall be any date selected by the Company, not more than 180 days after receipt by the Company of such written demand for redemption. (d) to the extent that any of the 2004 Series C Authority Bonds shall have become Provider Bonds, (i) on the Provider Bond Redemption Date in an amount equal to the aggregate principal amount of Provider Bonds outstanding at the expiration of the Liquidity Facility at 100% of the principal amount thereof and (ii) in accordance with any other redemption provisions set forth in any applicable Standby Bond Purchase Agreement.

Such redemption date may be any day not more than 180 days after the occurrence of such "final determination". If the Trustee does not receive written notice of such selection by the Company within 140 days after the date of the occurrence of such "final determination," then the redemption date shall be the 180th day after the occurrence of such "final determination." On or before such redemption date, the Company shall deposit with the Trustee, as paying agent hereunder, the total redemption price of the bonds so called, with interest accrued thereon to the redemption date, less any credits to which the Company may be entitled pursuant to Section 3.01 hereof, and the Trustee, as such paying agent, shall apply such funds, on the redemption date, to the redemption of the bonds so called. The delivery to the Authority Trustee of a certified copy of such resolution shall constitute notice to the Authority Trustee of the redemption referred to therein on the terms specified therein. (c) The Company shall, within 10 days after the receipt of a written demand under subsection (c) of Section 2.01 hereof, by resolution of its Board of Directors, fix a redemption date for such redemption and shall deliver to the Trustee, the Authority and the Authority Trustee a certified copy of said resolution at least 40 days prior to the date so selected for redemption.

If the Trustee does not receive written notice of such selection by the Company within 140 days after the date of the receipt of such written demand, then the redemption date shall be the 180th day after the receipt of such written demand. On or before such redemption date, the Company shall deposit with the Trustee, as paying agent hereunder, the total redemption price of the bonds so called, with interest accrued thereon to the redemption date, less any credits to which the Company may be entitled pursuant to Section 3.01 hereof, and the Trustee, as such paying agent, shall apply such funds, on the redemption date, to the redemption of the bonds so called.

From and after the date when each bond or portion thereof of the Pollution Control Series AE shall be due and payable as aforesaid (unless upon said date the full amount due thereon shall not be held by or provided to the Trustee, as paying agent hereunder, and be immediately available for payment), all further interest shall cease to accrue on such bond or on such portion thereof, as the case may be. SECTION 2.04. Bonds Called in Part. If only a portion of any bond of the Pollution Control Series AE shall be called for redemption pursuant to Section 2.02 hereof, the notice of redemption hereinbefore provided for shall specify the portion of the principal amount thereof to be redeemed.
