(ii) The Company shall give written notice of any such conversion to the Auction Agent, any Remarketing Agent, the Issuer, the Trustee and any provider of a Credit Facility not less than seven (7) Business Days prior to the date on which the Trustee is required to notify the Owners of the conversion pursuant to subparagraph (iii) below. Such notice shall specify the PARS Rate Conversion Date and the length of the initial Auction Period. Together with such notice, the Company shall file with the Issuer, the Trustee and any provider of a Credit Facility a Favorable Opinion of Bond Counsel. -23- 29 No such change to a PARS Rate Period shall become effective unless the Company shall also file, with the Issuer and the Trustee, such a Favorable Opinion of Bond Counsel dated the PARS Rate Conversion Date. (iii) Not less than fifteen (15) days prior to the PARS Rate Conversion Date the Trustee shall mail a written notice of the conversion to the Owners of all Bonds to be converted; provided, however, that the Trustee shall not mail such written notice if converting from a Flexible Rate Period until it has received a written confirmation from the Remarketing Agent that no Flexible Segment for the Bonds extends beyond the PARS Rate Conversion Date. Such notice shall state that the Bonds to be converted will be subject to mandatory purchase on the PARS Rate Conversion Date at the purchase price determined pursuant to Section 3.02(a) and will specify the time at which Bonds are to be tendered for purchase. (iv) The PARS Rate for the Auction Period commencing on the PARS Rate Conversion Date shall be determined by the Broker-Dealer before the Conversion Date and shall be the lowest rate which, in the judgment of the Broker-Dealer, is necessary to enable the Bonds to be remarketed at the principal amount thereof, plus accrued interest, if any, on the PARS Rate Conversion Date. Such determination shall be conclusive and binding upon the Issuer, the Company, the Trustee, the Auction Agent and the Owners and Beneficial Owners of the Bonds to which such rate will be applicable. (v) Not later than 5:00 p.m., New York, New York time, on the date of determination of the PARS Rate, the Broker-Dealer shall notify the Trustee and the Company of such rate by telephone confirmed in writing.

(vi) The Company may revoke its election to effect a conversion of the interest rate on any Bonds to a PARS Rate by giving written notice of such revocation to the Issuer, the Trustee, the Remarketing Agent, the Auction Agent, the Broker-Dealer and any provider of a Credit Facility at any time prior to the setting of the PARS Rate by the Broker-Dealer. (c) Conversions From PARS Rate Periods. At the option of the Company and subject to Section 2.02(e), all of the Bonds may be converted from a PARS Rate Period to a Daily Interest Rate Period, a Weekly Interest Rate Period, a Term Interest Rate Period or a Flexible Interest Rate Period, as follows: (i) If the PARS are in an Auction Period other than the daily Auction Period, the conversion date shall be the second regularly scheduled Interest Payment Date following the final Auction Date. If the PARS are in a daily Auction Period, the conversion date shall be the next regularly scheduled Interest Payment Date. (ii) The Company shall give written notice of any such conversion to the Issuer, the Trustee, the Auction Agent, the Broker-Dealer and any provider of a Credit -24- 30 Facility not less than seven (7) Business Days prior to the date on which the Trustee is required to notify the Owners of the conversion pursuant to subparagraph (iii) below. Such notice shall specify the conversion date and the Rate Period to which the conversion will be made and, if applicable, the length of any Term Rate Period. Together with such notice, the Company shall file with the Issuer and the Trustee a Favorable Opinion of Bond Counsel regarding such conversion. No conversion shall become effective unless the Company shall also file, with the Issuer, the Trustee and any provider of a Credit Facility, such a Favorable Opinion of Bond Counsel dated the date of such conversion. (iii) Not less than twenty (20) days prior to the conversion date, the Trustee shall mail a written notice of the conversion to the Owners of all Bonds to be converted, specifying the Rate Period to which the Bonds are being converted, stating that the Bonds to be converted will be subject to mandatory purchase on the conversion date at the purchase price determined pursuant to Section 3.02(a), specifying the time at which Bonds are to be tendered for purchase, stating any conditions precedent to such conversion and stating that, if such conditions are not satisfied, the Bonds will continue to bear interest at PARS Rates but that the Bonds will be subject to mandatory purchase in accordance with the last paragraph of Section 2.08 hereof. SECTION 2.04. DAILY INTEREST RATE; ADJUSTMENT TO DAILY INTEREST RATE PERIOD. (a) Determination of Daily Interest Rate. During each Daily Interest Rate Period, the Bonds shall bear interest at the Daily Interest Rate determined by the Remarketing Agent on each Business Day for such Business Day. The Daily Interest Rate shall be the rate determined by the Remarketing Agent (based on an examination of Tax-Exempt obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under then-prevailing market conditions) to be the lowest rate which would enable the Remarketing Agent to sell the Bonds on the effective date of such rate at a price (without regard to accrued interest) equal to 100% of the principal amount thereof. If the Remarketing Agent shall not have determined a Daily Interest Rate for any day by 10:00 a.m., New York, New York time, the Daily Interest Rate for such day shall be the same as the Daily Interest Rate for the immediately preceding day. The Remarketing Agent shall notify the Company, the Trustee and the Paying Agent of each Daily Interest Rate on the date of the determination thereof by written notice communicated by electronic mail, by facsimile or by other means acceptable to the Company, the Trustee, and the Paying Agent. (b) Adjustment to Daily Interest Rate Period. At any time, the Company, by written notice to the Issuer, the Trustee, the Paying Agent and the Remarketing Agent may, subject to Section 2.02(e), elect that the Bonds shall bear interest at a Daily Interest Rate. Such notice (A) shall specify the effective date of such adjustment to a Daily Interest Rate, which shall be (1) a Business Day not earlier than the fifteenth day following the fifth Business Day after the date of receipt by the Trustee and the Paying Agent of such notice (or such shorter period after the date of such receipt as shall be acceptable to the Trustee); (2) in the case of an adjustment from a Term Interest Rate Period, a day on which the Bonds would be permitted to be redeemed at the option of the Company pursuant to Section 4.02(b)(iv) hereof or the day immediately following the last day of the then-current Term Interest Rate Period, and (3) in the case of an adjustment from a -25- 31 Flexible Interest Rate Period, the day immediately following the last day of the then-current Flexible Interest Rate Period as determined in accordance with Section 2.07(d) hereof; provided, however, that if prior to the Company's mailing of notice of such election, any Bonds shall have been called for redemption and such redemption shall not have theretofore been effected, the effective date of such Daily Interest Rate Period shall not precede such redemption date; and (B) if the adjustment is from a Term Interest Rate Period having a duration in excess of one year, shall be accompanied by a Favorable Opinion of Bond Counsel with respect to such adjustment. (c) Notice of Adjustment to Daily Interest Rate Period. The Trustee shall give notice by Mail of an adjustment to a Daily Interest Rate Period to the Owners not less than 15 days prior to the effective date of such Daily Interest Rate Period. Such notice shall state (A) that the interest rate on the Bonds will be adjusted to a Daily Interest Rate (subject to the Company's ability to rescind its election as provided in Section 2.08 hereof), (B) the effective date of such Daily Interest Rate Period, (C) that such Bonds are subject to mandatory purchase on such effective date, (D) the procedures for such mandatory purchase, (E) the purchase price of such Bonds on such effective date (expressed as a percentage of the principal amount thereof), and (F) that the Owners of such Bonds do not have the right to retain their Bonds on such effective date. SECTION 2.05. WEEKLY INTEREST RATE; ADJUSTMENT TO WEEKLY INTEREST RATE PERIOD. (a) Determination of Weekly Interest Rate. During each Weekly Interest Rate Period, the Bonds shall bear interest at the Weekly Interest Rate determined by the Remarketing Agent no later than the first day of such Weekly Interest Rate Period and thereafter no later than Tuesday of each week during such Weekly Interest Rate Period, unless any such Tuesday shall not be a Business Day, in which event the Weekly Interest Rate shall be determined by the Remarketing Agent no later than the Business Day next preceding such Tuesday. The Weekly Interest Rate shall be the rate determined by the Remarketing Agent (based on an examination of Tax-Exempt obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under then prevailing market conditions) to be the lowest rate which would enable the Remarketing Agent to sell the Bonds on the effective date of such rate at a price (without regard to accrued interest) equal to 100% of the principal amount thereof. If the Remarketing Agent shall not have determined a Weekly Interest Rate for any period, the Weekly Interest Rate shall be the same as the Weekly Interest Rate in effect for the immediately preceding week. The first Weekly Interest Rate determined for each Weekly Interest Rate Period shall apply to the period commencing on the first day of such Weekly Interest Rate Period and ending on the next succeeding Tuesday. Thereafter, each Weekly Interest Rate shall apply to the period commencing on each Wednesday and ending on the next succeeding Tuesday, unless such Weekly Interest Rate Period shall end on a day other than Tuesday, in which event the last Weekly Interest Rate for such Weekly Interest Rate Period shall apply to the period commencing on the Wednesday preceding the last day of such Weekly Interest Rate Period and ending on such last day. The Remarketing Agent shall notify the Company, the Trustee and the Paying Agent of each Weekly Interest Rate on the date of the determination thereof by written notice communicated by electronic mail, by facsimile or by other means acceptable to the Company, the Trustee, and the Paying Agent. -26- 32 (b) Adjustment to Weekly Interest Rate Period. The Company, by written notice to the Issuer, the Trustee, the Paying Agent and the Remarketing Agent may, subject to Section 2.02(e), at any time elect that the Bonds shall bear interest at a Weekly Interest Rate. Such notice (A) shall specify the effective date of such adjustment to a Weekly Interest Rate, which shall be (1) a Business Day not earlier than the fifteenth day following the fifth Business Day after the date of receipt by the Trustee and the Paying Agent of such notice (or such shorter period after the date of such receipt as shall be acceptable to the Trustee); (2) in the case of an adjustment from a Term Interest Rate Period, a day on which the Bonds would be permitted to be redeemed at the option of the Company pursuant to Section 4.02(b)(iv) hereof or the day immediately following the last day of the then-current Term Interest Rate Period; and (3) in the case of an adjustment from a Flexible Interest Rate Period the day immediately following the last day of the then-current Flexible Interest Rate Period as determined in accordance with Section 2.07(d); provided however, that if prior to the Company's making such election, any Bonds shall have been called for redemption and such redemption shall not have theretofore been effected, the effective date of such Weekly Interest Rate Period shall not precede such redemption date; and (B) if the adjustment is from a Term Interest Rate Period having a duration in excess of one year, shall be accompanied by a Favorable Opinion of Bond Counsel with respect to such adjustment. (c) Notice of Adjustment to Weekly Interest Rate Period. The Trustee shall give notice by Mail of an adjustment to a Weekly Interest Rate Period to the Owners not less than 15 days prior to the effective date of such Weekly Interest Rate Period. Such notice shall state (A) that the interest rate on the Bonds will be adjusted to a Weekly Interest Rate (subject to the Company's ability to rescind its election as provided in Section 2.08 hereof), (B) the effective date of such Weekly Interest Rate Period, (C) that such Bonds are subject to mandatory purchase on such effective date, (D) the procedures for such mandatory purchase, (E) the purchase price of such Bonds on such effective date (expressed as a percentage of the principal amount thereof), and (F) that the Owners of such Bonds do not have the right to retain their Bonds on such effective date. SECTION 2.06. TERM INTEREST RATE; ADJUSTMENT TO TERM INTEREST RATE PERIOD. (a) Determination of Term Interest Rate. During each Term Interest Rate Period, the Bonds shall bear interest at the Term Interest Rate determined by the Remarketing Agent on a Business Day selected by the Remarketing Agent, but not more than 60 days prior to and not later than the effective date of such Term Interest Rate Period. The Term Interest Rate shall be the rate determined by the Remarketing Agent on such date as being the lowest rate (based on an examination of Tax-Exempt obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under then prevailing market conditions) which would enable the Remarketing Agent to sell the Bonds on the effective date of such Term Interest Rate Period at a price (without regard to accrued interest) equal to 100% of the principal amount thereof, provided however, that if, for any reason, a Term Interest Rate for any Term Interest Rate Period shall not be determined or become effective, then (A) in the event the then-current Term Interest Rate Period is for one year or less, the Rate Period for the Bonds shall automatically convert to a Daily Interest Rate Period and (B) in the event the current Term Interest Rate Period is for more than one year, the Rate Period for the Bonds shall automatically adjust to a Term Interest Rate Period of one year and one day; provided, however, that if the last day of any successive Term -27- 33 Interest Rate Period shall not be a day immediately preceding a Business Day, then such successive Term Interest Rate Period shall end on the first day immediately preceding the Business Day next succeeding such day or, if such Term Interest Rate Period would end after the day prior to the final maturity date of the Bonds, the next succeeding Rate Period shall be a Term Interest Rate Period ending on the day prior to the final maturity date of the Bonds; provided further that in the case of clause (B) above, if the Company delivers to the Trustee a Favorable Opinion of Bond Counsel prior to the end of the then-effective Term Interest Rate Period, the Rate Period for the Bonds will adjust to a Daily Interest Rate Period. If the Daily Interest Rate for the first day of a Daily Interest Rate Period described in clause (A) above is not determined as provided in Section 2.04(a) hereof the Daily Interest Rate for the first day of such Daily Interest Rate Period shall be 110% of the most recent PSA Municipal Swap Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the PSA Municipal Swap Index, the variable rate index contained in the publication determined by the Remarketing Agent, or, if the Remarketing Agent is the Trustee, determined by the Company, as the most comparable to The Bond Buyer). If a Term Interest Rate for any such Term Interest Rate Period described in clause (B) above is not determined as described in the first sentence of this Section 2.06(a), the Term Interest Rate for such Term Interest Rate Period shall be 110% of the most recent One-Year Note Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the One-Year Note Index, the one-year note index contained in the publication determined by the Remarketing Agent, or, if the Remarketing Agent is the Trustee, determined by the Company, as the most comparable to The Bond Buyer). The Remarketing Agent shall notify the Company, the Trustee and the Paying Agent of each Term Interest Rate on the date of the determination thereof by written notice communicated by electronic mail, by facsimile or by other means acceptable to the Company, the Trustee, and the Paying Agent. (b) Adjustment to or Continuation of Term Interest Rate Period. At any time, the Company, by written notice to the Issuer, the Trustee, the Paying Agent and the Remarketing Agent, may, subject to Section 2.02(e), elect that the Bonds shall bear, or continue to bear, interest at a Term Interest Rate and shall determine the duration of the Term Interest Rate Period during which such Bonds shall bear interest at such Term Interest Rate. At the time the Company so elects an adjustment to or continuation of a Term Interest Rate Period, the Company may specify two or more consecutive Term Interest Rate Periods and, if the Company so specifies, shall specify the duration of each such Term Interest Rate Period as provided in this paragraph (b). Such notice shall specify the effective date of each Term Interest Rate Period, which shall be (A) a Business Day not earlier than the fifteenth day following the fifth Business Day after the date of receipt by the Trustee and the Paying Agent of such notice (or such shorter period after the date of such receipt as shall be acceptable to the Trustee); (B) in the case of an adjustment from a Term Interest Period to a Term Interest Period of a different duration or the continuation of a Term Interest Rate Period, a day on which the Bonds would be permitted to be redeemed at the option of the Company pursuant to Section 4.02(b)(iv) hereof or the day immediately following the last day of the then-current Term Interest Rate Period; and (C) in the case of an adjustment from a Flexible Interest Rate Period the day immediately following the last day of the then-current Flexible Interest Rate Period as determined in accordance with Section 2.07(d) hereof; provided, however, that if prior to the Company's making such election, any Bonds shall have been called for redemption and such redemption shall not have theretofore been effected, the -28- 34 effective date of such Term Interest Rate Period shall not precede such redemption date. In addition, such notice (x) shall specify the last day of such Term Interest Rate Period (which shall be either the day preceding the date of final maturity of the Bonds or a day which both immediately precedes a Business Day and is at least 180 days after such effective date), and (y) unless such Term Interest Rate Period immediately succeeds a Term Interest Rate Period of the same duration and is subject to the same optional redemption rights under Section 4.02(b)(iv) hereof, shall be accompanied by a Favorable Opinion of Bond Counsel with respect to such adjustment. If, by 15 days prior to the end of the then-current Term Interest Rate Period, the Trustee shall not have received notice of the Company's election that the Bonds shall bear interest at a PARS Rate, a Daily Interest Rate, a Weekly Interest Rate, a Term Interest Rate or a Flexible Interest Rate, (A) in the event the then-current Term Interest Rate Period is for one year or less, the Rate Period for the Bonds shall automatically convert to a Daily Interest Rate Period and (B) in the event the current Term Interest Rate Period is for more than one year, the Rate Period for the Bonds shall automatically adjust to a Term Interest Rate Period of one year and one day, provided however, that if the last day of any successive Term Interest Rate Period shall not be a day immediately preceding a Business Day, then such successive Term Interest Rate Period shall end on the first day immediately preceding the Business Day next succeeding such day or, if such Term Interest Rate Period would end after the day prior to the Maturity Date, the next succeeding Rate Period shall be a Term Interest Rate Period ending on the day prior to the Maturity Date; provided however, that in the case of clause (B) above, if the Company delivers to the Trustee a Favorable Opinion of Bond Counsel prior to the end of the then-effective Term Interest Rate Period, the Rate Period for the Bonds will adjust to a Daily Interest Rate Period. If the Daily Interest Rate for the first day of a Daily Interest Rate Period described in clause (A) above is not determined as provided in Section 2.04(a) hereof, the Daily Interest Rate for the first day of such Daily Interest Rate Period shall be 110% of the most recent PSA Municipal Swap Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the PSA Municipal Swap Index, the variable rate index contained in the publication determined by the Remarketing Agent, or, if the Remarketing Agent is the Trustee, determined by the Company, as the most comparable to The Bond Buyer). If a Term Interest Rate for any such Term Interest Rate Period described in clause (B) above is not determined as described in the first sentence of this Section 2.06(a), the Term Interest Rate for such Term Interest Rate Period shall be 110% of the most recent One-Year Note Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the One-Year Note Index, the one-year note index contained in the publication determined by the Remarketing Agent, or, if the Remarketing Agent is the Trustee, determined by the Company, as the most comparable to The Bond Buyer). At the same time that the Company elects to have the Bonds bear interest at a Term Interest Rate or to continue to bear interest at a Term Interest Rate, the Company may also elect that such Term Interest Rate Period shall be automatically renewed for successive Term Interest Rate Periods each having the same duration as the Term Interest Rate Period so specified; provided however, that such election must be accompanied by a Favorable Opinion of Bond Counsel with respect to such continuing automatic renewals of such Term Interest Rate Period. If such election is made, no Favorable Opinion of Bond Counsel shall be required in connection -29- 35 with the commencement of each successive Term Interest Rate Period determined in accordance with such election. Further, at the same time that the Company elects to have the Bonds bear interest at a Term Interest Rate or continue to bear interest at a Term Interest Rate, subject to the provisions of Section 4.02(c) hereof the Company may also specify to the Trustee optional redemption prices and periods different from those set out in Section 4.02 hereof during the Term Interest Rate Period(s) with respect to which such election is made. (c) Notice of Adjustment to or Continuation of Term Interest Rate Period. The Trustee shall give notice by Mail of an adjustment to or continuation of a Term Interest Rate Period to the Owners not less than 15 days prior to the effective date of such Term Interest Rate Period. Such notice shall state (A) that the interest rate on the Bonds will be adjusted to, or continue to be, a Term Interest Rate (subject to the Company's ability to rescind its election as provided in Section 2.08 hereof), (B) the effective date and the last date of such Term Interest Rate Period, (C) that the Term Interest Rate for such Term Interest Rate Period will be determined not later than the effective date thereof (D) how such Term Interest Rate may be obtained from the Remarketing Agent, (E) the Interest Payment Dates after such effective date, (F) that, during such Term Interest Rate Period, the Owners of such Bonds will not have the right to tender their Bonds for purchase, (G) the redemption provisions that will apply to the Bonds during such Term Interest Rate Period, and (H) that, except when the new Term Interest Rate Period is preceded by a Term Interest Rate Period of the same duration, such Bonds are thereby subject to mandatory purchase on such effective date, the procedures for such mandatory purchase, the purchase price of such Bonds on such effective date (expressed as a percentage of the principal amount thereof), and the Owners of such Bonds do not have the right to retain their Bonds on such effective date. SECTION 2.07. FLEXIBLE INTEREST RATE; ADJUSTMENT TO FLEXIBLE INTEREST RATE PERIOD. (a) Determination of Flexible Segments and Flexible Interest Rates. During each Flexible Interest Rate Period, each Bond shall bear interest during each Flexible Segment for such Bond at the Flexible Interest Rate for such Bond as described herein. Each Flexible Segment and Flexible Interest Rate for each Bond shall be the Flexible Segment and Flexible Interest Rate determined by the Remarketing Agent. Each Flexible Segment for any Bond shall be a period of not less than one nor more than 270 days (subject to any limitations set forth in the Remarketing Agreement), determined by the Remarketing Agent to be, in its judgment, the period which, together with all other Flexible Segments for the Bonds then outstanding, is likely to result in the lowest overall net interest expense on the Bonds; provided however, that (A) any such Bond purchased on behalf of the Company and remaining unsold in the hands of the Remarketing Agent as of the close of business on the effective date of the Flexible Segment for such Bond shall have a Flexible Segment of one day or, if such Flexible Segment would not end on a day immediately preceding a Business Day, a Flexible Segment of more than one day ending on the day immediately preceding the next Business Day and (B) each Flexible Segment shall end on a day which immediately precedes a Business Day and no Flexible Segment shall extend beyond the final maturity date of the Bonds. The Flexible Interest Rate for each Flexible Segment for each Bond shall be the rate determined by the Remarketing Agent (based on an examination of Tax-Exempt obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under -30- 36 then prevailing market conditions) no later than the first day of such Flexible Segment (and in the case of a Flexible Segment of one day, no later than 12:30 p.m. New York, New York time, on such date) to be the lowest rate which would enable the Remarketing Agent to sell the Bonds on the effective date of such rate at a price (without regard to accrued interest) equal to 100% of the principal amount thereof. If a Flexible Segment or a Flexible Interest Rate for a Flexible Segment is not determined or effective, the Flexible Segment for such Bond shall be a Flexible Segment of one day, and the interest rate for such Flexible Segment of one day shall be 110% of the most recent PSA Municipal Swap Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the PSA Municipal Swap Index, the variable rate index contained in the publication determined by the Remarketing Agent, or, if the Remarketing Agent is the Trustee, determined by the Company, as most comparable to The Bond Buyer). The Remarketing Agent shall notify the Company, the Trustee and the Paying Agent of each Flexible Interest Rate and Flexible Segment on the date of the determination thereof by written notice communicated by electronic mail, by facsimile or by other means acceptable to the Company, the Trustee, and the Paying Agent. (b) Adjustment to Flexible Interest Rate Period. At any time, the Company, by written notice to the Issuer, the Trustee, the Paying Agent and the Remarketing Agent, may, subject to Section 2.02(e), elect that the Bonds shall bear interest at Flexible Interest Rates. Such notice (A) shall specify the effective date of the Flexible Interest Rate Period during which such Bonds shall bear interest at Flexible Interest Rates, which shall be (1) a Business Day not earlier than the fifteenth day following the fifth Business Day after the date of receipt by the Trustee and the Paying Agent of such notice (or such shorter period after the date of such receipt as shall be acceptable to the Trustee), and (2) in the case of an adjustment from a Term Interest Rate Period, a day on which the Bonds would be permitted to be redeemed at the option of the Company pursuant to Section 4.02(b)(iv) hereof or the day immediately following the last day of the then-current Term Interest Rate Period, provided however, that if prior to the Company's making such election any Bonds shall have been called for redemption and such redemption shall not have theretofore been effected, the effective date of such Flexible Interest Rate Period shall not precede such redemption date; and (B) in the case of an adjustment from a Term Interest Rate Period having a duration in excess of one year, shall be accompanied by a Favorable Opinion of Bond Counsel with respect to such adjustment. During each Flexible Interest Rate Period commencing on the date so specified (provided that the Favorable Opinion of Bond Counsel described in clause (B) above, if required, is reaffirmed as of such date) and ending on the day immediately preceding the effective date of the next succeeding Rate Period, each Bond shall bear interest at a Flexible Interest Rate during each Flexible Segment for such Bond. (c) Notice of Adjustment to Flexible Interest Rate Period. The Trustee shall give notice by Mail of an adjustment to a Flexible Interest Rate Period to the Owners not less than 15 days prior to the effective date of such Flexible Interest Rate Period. Such notice shall state (A) that the interest rate on the Bonds will be adjusted to Flexible Interest Rates (subject to the Company's ability to rescind its election as provided in Section 2.08 hereof), (B) the effective date of such Flexible Interest Rate Period, (C) that such Bonds are thereby subject to mandatory purchase on the effective date of such Flexible Interest Rate Period, (D) the procedures for such mandatory purchase, (E) the purchase price of such Bonds on such effective date (expressed as a -31- 37 percentage of the principal amount thereof), and (F) that the Owners of such Bonds do not have the right to retain their Bonds on such effective date. (d) Adjustment From Flexible Interest Rates. At any time during a Flexible Interest Rate Period, the Company may elect that the Bonds shall no longer bear interest at Flexible Interest Rates and shall instead bear interest as otherwise permitted under this Indenture. The Company shall notify the Issuer, the Trustee, the Paying Agent and the Remarketing Agent of such election by Mail and shall specify the Rate Period to follow with respect to such Bonds upon cessation of the Flexible Interest Rate Period and instruct the Remarketing Agent to determine Flexible Segments of such duration that, as soon as possible, all Flexible Segments shall end on the same date, not earlier than the day that would permit the notices required by Sections 2.03(b)(iii), 2.04(c), 2.05(c) or 2.06(c), as applicable, to be given, and such date shall be the last day of the then current Flexible Interest Rate Period. Upon the establishment of such Flexible Segments, the day next succeeding the last day of all such Flexible Segments shall be the effective date of the Rate Period elected by the Company. The Remarketing Agent, promptly upon the determination thereof, shall give written notice of such last day and such effective dates to the Issuer, the Company, the Trustee and the Paying Agent. SECTION 2.08. RESCISSION OF ELECTION. Notwithstanding anything herein to the contrary, the Company may rescind any election by it to adjust to or, in the case of a Term Interest Rate Period, continue a Rate Period pursuant to Section 2.03, Section 2.04, Section 2.05, Section 2.06 or Section 2.07 hereof prior to the effective date of such adjustment or continuation or, as provided in Section 2.03(b)(vi) hereof, prior to the setting of the PARS Rate by the Broker-Dealer, by giving written notice thereof to the Issuer, the Trustee, the Paying Agent, any Auction Agent and any Remarketing Agent prior to such effective date. At the time that the Company gives notice of rescission, it may also elect in such notice to continue the Rate Period then in effect; provided however, that if the Rate Period then in effect is a Term Interest Rate Period, the subsequent Term Interest Rate Period shall not be of a different duration than the Term Interest Rate Period then in effect unless the Company provides to the Trustee a Favorable Opinion of Bond Counsel prior to the expiration of the then-current Term Interest Rate Period. If the Trustee receives notice of such rescission prior to the time the Trustee has given notice to the Owners of the Bonds of the change in or continuation of Rate Periods pursuant to Section 2.03, Section 2.04, Section 2.05, Section 2.06 or Section 2.07 hereof, then such notice of change in or continuation of Rate Periods shall be of no force and effect and shall not be given to the Owners. If the Trustee receives notice of such rescission after the Trustee has given notice to the Owners of the Bonds pursuant to Section 2.03, Section 2.04, Section 2.05, Section 2.06 or Section 2.07 hereof of an adjustment from any Rate Period other than a Term Interest Rate Period in excess of one year or if an attempted adjustment from one Rate Period (other than a Term Interest Rate Period in excess of one year) to another Rate Period does not become effective for any other reason, and if the Company does not elect to continue the Rate Period then in effect, then the Rate Period for the Bonds shall automatically adjust to or continue in a Daily Interest Rate Period and the Trustee shall promptly give notice thereof to the Owners of the Bonds. If the Trustee receives notice of such rescission after the Trustee has given notice to the Owners of the Bonds pursuant to Section 2.03, Section 2.04, Section 2.05, Section 2.06 or Section 2.07 hereof of an adjustment from a Term Interest Rate Period in excess of one year to another Rate Period (including a Term Interest Rate Period of a different duration), or if an attempted adjustment from -32- 38 a Term Interest Rate Period in excess of one year to another Rate Period (including a Term Interest Rate Period of a different duration) does not become effective for any reason and if the Company does not elect to continue the Rate Period then in effect, then the Rate Period for the Bonds shall continue to be a Term Interest Rate Period of the same duration as the immediately preceding Term Interest Rate Period, subject to the second proviso contained in Section 2.06(a); provided that if the Company delivers to the Trustee a Favorable Opinion of Bond Counsel prior to the end of the then-effective Term Interest Rate Period, the Rate Period for the Bonds shall be as directed by the Company in writing. If a Daily Interest Rate for the first day of any Daily Interest Rate Period to which a Rate Period is adjusted under this Section 2.08 is not determined as provided in Section 2.04(a) hereof, the Daily Interest Rate for the first day of such Daily Interest Rate Period shall be 110% of the most recent PSA Municipal Swap Index theretofore published in The Bond Buyer (or, if The Bond Buyer is no longer published or no longer publishes the PSA Municipal Swap Index, the variable rate index contained in the publication determined by the Remarketing Agent or if the Remarketing Agent is the Trustee, determined by the Company, as most comparable to The Bond Buyer). The Trustee shall promptly give written notice of each such automatic adjustment to a Rate Period pursuant to this Section 2.08 to the Owners in the form provided in Section 2.04(c) hereof. Notwithstanding the rescission by the Company of any notice to adjust to or from or continue a Rate Period, if notice has been given to Owners pursuant to Section 2.03(b)(iii), Section 2.03(c)(iii), Section 2.04(c), Section 2.05(c), Section 2.06(c) or Section 2.07(c), the Bonds shall be subject to mandatory purchase as specified in such notice. SECTION 2.09. FORM OF BONDS. The Bonds and the certificate of authentication to be executed thereon shall be in substantially the form attached hereto as Exhibit A, with such appropriate variations, omissions and insertions as are permitted or required by this Indenture. Upon adjustment to a Term Interest Rate Period, the form of Bond may include a summary of the mandatory and optional redemption provisions to apply to the Bonds during such Term Interest Rate Period, or a statement to the effect that the Bonds will not be optionally redeemed during such Term Interest Rate Period; provided that the Registrar shall not authenticate such a revised Bond form prior to receiving a Favorable Opinion of Bond Counsel that such Bond form satisfies the requirements of the Act and of this Indenture and that authentication thereof will not adversely affect the Tax-Exempt status of the Bonds. SECTION 2.10. EXECUTION OF BONDS. The Bonds shall be signed in the name and on behalf of the Issuer with the manual or facsimile signature of its Mayor and attested by the manual or facsimile signature of the City Clerk. The Bonds shall then be delivered to the Registrar for authentication by it. In case any officer who shall have signed any of the Bonds shall cease to be such officer before the Bonds so signed or attested shall have been authenticated or delivered by the Registrar or issued by the Issuer, such Bonds may nevertheless be authenticated, delivered and issued and, upon such authentication, delivery and issuance, shall be as binding upon the Issuer as though those who signed and attested the same had continued to be such officers of the Issuer. Also, any Bond may be signed on behalf of the Issuer by such persons as on the actual date of the execution of such Bond shall be the proper officers although on the nominal date of such Bond any such person shall not have been such officer. -33- 39 Only such of the Bonds as shall bear thereon a certificate of authentication in the form set forth in Exhibit A hereto, manually executed by an authorized signatory of the Registrar, shall be valid or obligatory for any purpose or entitled to the benefits of this Indenture, and such certificate of the Registrar shall be conclusive evidence that the Bonds so authenticated have been duly authenticated and delivered hereunder and are entitled to the benefits of this Indenture. Upon authentication of any Bond, the Registrar shall set forth on such Bond (1) the date of such authentication and (2) in the case of a Bond bearing interest at a Flexible Interest Rate and not registered in the book-entry system pursuant to Section 2.16 hereof, such Flexible Interest Rate, the last day of the applicable Flexible Segment, the number of days comprising such Flexible Segment and the amount of interest to accrue during such Flexible Segment. SECTION 2.11. TRANSFER AND EXCHANGE OF BONDS. Registration of any Bond may, in accordance with the terms of this Indenture, be transferred at the Principal Office of the Registrar, upon the books of the Registrar required to be kept pursuant to the provisions of Section 2.12 hereof, by the Person in whose name it is registered, in person or by its attorney duly authorized in writing, upon surrender of such Bond for cancellation, accompanied by a written instrument of transfer in a form approved by the Registrar, duly executed. The Registrar shall require the payment by the Owner of the Bond requesting such transfer of any tax or other governmental charge required to be paid and there shall be no other charge to any Owners for any such transfer. Whenever any Bond shall be surrendered for registration of transfer, the Issuer shall execute and the Registrar shall authenticate and deliver a new Bond or Bonds of the same tenor and of Authorized Denominations. Except with respect to Bonds purchased pursuant to Sections 3.01 and 3.02 hereof, no registration of transfer of Bonds shall be required to be made for a period of fifteen (15) days next preceding the date on which the Trustee Mails any notice of redemption, nor shall any registration of transfer of Bonds called for redemption be required, except the unredeemed portion of any Bond being redeemed in part. Bonds may be exchanged at the Principal Office of the Registrar for a like aggregate principal amount of Bonds of the same tenor and of Authorized Denominations. The Registrar shall require the payment by the Owner of the Bond requesting such exchange of any tax or other governmental charge required to be paid with respect to such exchange, and there shall be no other charge to any Owners for any such exchange. Except with respect to Bonds purchased pursuant to Section 3.01 and Section 3.02 hereof, no exchange of Bonds shall be required to be made for a period of fifteen (15) days next preceding the date on which the Trustee Mails notice of redemption, nor shall any exchange of Bonds called for redemption be required, except the unredeemed portion of any Bond being redeemed in part. The Issuer, the Registrar, the Trustee and any agent of the Issuer, the Registrar or the Trustee may treat the person in whose name the Bond is registered as the owner thereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not the Bond be overdue, and neither the Issuer, the Registrar, the Trustee, any paying agent nor any such agent shall be affected by notice to the contrary. SECTION 2.12. BOND REGISTER. The Registrar will keep or cause to be kept at its Principal Office sufficient books for the registration and the registration of transfer of the Bonds, which -34- 40 shall at all times, during regular business hours, be open to inspection by the Issuer, the Trustee, the Provider, the Remarketing Agent and the Company; and, upon presentation for such purpose, the Registrar shall under such reasonable regulations as it may prescribe, register the transfer or cause to be registered the transfer, on said books, Bonds as hereinbefore provided. SECTION 2.13. BONDS MUTILATED, LOST, DESTROYED OR STOLEN. If any Bond shall become mutilated, the Issuer, upon the request and at the expense of the Owner of said Bond, shall execute, and the Registrar shall thereupon authenticate and deliver, a new Bond of like tenor and number in exchange and substitution for the Bond so mutilated, but only upon surrender to the Registrar of the Bond so mutilated. Every mutilated Bond so surrendered to the Registrar shall be canceled by it and delivered to the Company. If any Bond issued hereunder shall be lost, destroyed or stolen, evidence of such loss, destruction or theft may be submitted to the Issuer, the Company and the Registrar, and if such evidence shall be satisfactory to them and indemnity satisfactory to them shall be given, the Issuer, at the expense of the Owner, shall execute, and the Registrar shall thereupon authenticate and deliver, a new Bond of like tenor in lieu of and in substitution for the Bond so lost, destroyed or stolen (or if any such Bond shall have matured or shall be about to mature, instead of issuing a substitute Bond the Registrar may pay the same without surrender thereof). The Issuer may require payment of a reasonable fee for each new Bond issued under this Section and payment of the expenses which may be incurred by the Issuer and the Registrar. Any Bond issued under the provisions of this Section in lieu of any Bond alleged to be lost, destroyed or stolen shall constitute an original additional contractual obligation on the part of the Issuer whether or not the Bond so alleged to be lost, destroyed or stolen be at any time enforceable by anyone, and shall be equally and proportionately entitled to the benefits of this Indenture with all other Bonds secured by this Indenture. To the extent permitted by law, the provisions of this Section are exclusive and shall preclude all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or stolen Bonds. SECTION 2.14. BONDS; LIMITED OBLIGATIONS. The Bonds, together with premium, if any, and interest thereon, shall be limited and not general obligations of the Issuer not constituting or giving rise to a pecuniary liability of the Issuer nor any charge against its general credit or taxing powers nor an indebtedness of or a loan of credit thereof within the meaning of any provision or limitation of the State Constitution or laws, shall be payable solely from the Revenues and other moneys pledged therefor under this Indenture, and shall be a valid claim of the respective Owners thereof only against the Bond Fund, the Revenues and other moneys held by the Trustee as part of the Trust Estate. The Issuer shall not be obligated to pay the purchase price of Bonds from any source. THE BONDS SHALL NOT BE DEEMED TO CONSTITUTE A DEBT, LIABILITY OR GENERAL OBLIGATION OF THE ISSUER, THE STATE OR OF ANY POLITICAL SUBDIVISION THEREOF, OR A PLEDGE OF THE FAITH AND CREDIT OF THE ISSUER, THE STATE OR OF ANY SUCH POLITICAL SUBDIVISION, BUT SHALL BE PAYABLE SOLELY FROM THE REVENUES AND PROCEEDS PROVIDED THEREFOR. THE ISSUER SHALL NOT BE OBLIGATED TO PAY THE SAME NOR INTEREST THEREON EXCEPT FROM THE REVENUES AND PROCEEDS PLEDGED THEREFOR, AND NEITHER THE FAITH AND CREDIT NOR THE TAXING POWER OF THE ISSUER, THE STATE OR OF ANY POLITICAL -35- 41 SUBDIVISION THEREOF IS PLEDGED TO THE PAYMENT OF THE PRINCIPAL OF OR THE INTEREST ON THE BONDS. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on any of the Bonds or for any claim based thereon or upon any obligation, covenant or agreement contained in this Indenture, the Bonds, the Agreement or any other related documents, against any past, present or future officer, elected official agent or employee of the Issuer, or any incorporator, officer, director or member of any successor corporation, as such, either directly or through the Issuer or any successor corporation, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such incorporator, officer, director or member as such is hereby expressly waived and released as a condition of and in consideration for the execution of this Indenture and the issuance of any of the Bonds. SECTION 2.15. DISPOSAL OF BONDS. Upon payment of the principal of, premium, if any, and interest represented thereby or transfer or exchange pursuant to Section 2.11 hereof or, replacement pursuant to Section 2.13 hereof, any Bond shall be canceled and such Bond shall be disposed of by the Registrar in accordance with its customary procedures and the Registrar shall provide evidence satisfactory to the Company of such cancellation and disposition. SECTION 2.16. BOOK-ENTRY SYSTEM. (a) Unless otherwise determined by the Issuer, the Bonds shall be issued in the form of a single certificated fully-registered Bond, registered in the name of Cede & Co., as nominee of DTC, or any successor nominee (the "Nominee"). The actual owners of the Bonds (the "Beneficial Owners") will not receive physical delivery of Bond certificates except as provided herein. Except as provided in paragraph (d) below, all of the outstanding Bonds shall be so registered in the registration books kept by the Registrar, and the provisions of this Section shall apply thereto. (b) With respect to Bonds registered on the registration books kept by the Registrar in the name of the Nominee, the Issuer, the Company, the Paying Agent, the Registrar, the Trustee and the Remarketing Agent shall have no responsibility or obligation to any DTC Participant or the Beneficial Owners. Without limiting the immediately preceding sentence, the Issuer, the Company, the Paying Agent, the Registrar, the Trustee and the Remarketing Agent shall have no responsibility or obligation to DTC, any DTC Participant or any Beneficial Owner with respect to (1) the accuracy of the records of DTC, the Nominee or any DTC Participant with respect to any ownership interest in the Bonds, (2) the delivery by DTC or any DTC Participant of any notice with respect to the Bonds, including any notice of redemption, or (3) the payment to any DTC Participant or Beneficial Owner of any amount with respect to principal or purchase price of, or premium, if any, or interest on, the Bonds. The Issuer, the Company, the Paying Agent, the Registrar, the Trustee and the Remarketing Agent may treat and consider the person in whose name each Bond is registered in the registration books kept by the Registrar as the owner and absolute owner of such Bond for the purpose of payment of principal purchase price, premium and interest with respect to such Bond, for the purpose of giving notices of redemption and other matters with respect to such Bond, for the purpose of registering transfers with respect to such -36- 42 Bond, and for all other purposes whatsoever. The Paying Agent shall pay all principal of and premium if any, and interest on, the Bonds only to or upon the order of the respective Owners, as shown in the registration books kept by the Registrar, or their respective attorneys duly authorized in writing, and all such payments shall be valid and effective to fully satisfy and discharge the Issuer's obligations with respect to payment of principal of, and premium, if any, and interest on, the Bonds to the extent of the sum or sums so paid. No person other than an Owner, as shown in the registration books kept by the Registrar, shall receive a certificated Bond evidencing the obligation of the Issuer to make payments of principal, premium, if any, and interest pursuant to this Indenture. (c) The Issuer, the Paying Agent, the Remarketing Agent and the Trustee shall execute and deliver to DTC a letter of representations in customary form with respect to the Bonds in book-entry form (the "DTC Representation Letter"), but such DTC Representation Letter shall not in any way limit the provisions of the foregoing paragraph (b) or in any other way impose upon the Issuer, the Trustee or the Paying Agent any obligation whatsoever with respect to persons having interests in the Bonds other than the Owners, as shown on the registration books kept by the Registrar. The Trustee, the Remarketing Agent and the Paying Agent shall take all action necessary for all representations of the Issuer in the DTC Representation Letter with respect to the Trustee, the Remarketing Agent and the Paying Agent to be complied with at all times, including but not limited to, the giving of all notices required under the DTC Representation Letter. The Trustee and Paying Agent are hereby authorized by the Issuer to enter into the DTC Representation Letter. (d) DTC may determine to discontinue providing its services with respect to the Bonds at any time by giving reasonable notice to the Issuer or the Trustee and discharging its responsibilities with respect thereto under applicable law. The Issuer, with the consent of the Company, may terminate the services of DTC with respect to the Bonds. Upon the discontinuance or termination of the services of DTC with respect to the Bonds, unless a substitute securities depository is appointed to undertake the functions of DTC hereunder, the Issuer, at the expense of the Company, is obligated to deliver Bond certificates to the Beneficial Owners of such Bonds, as described in this Indenture, and such Bonds shall no longer be restricted to being registered in the registration books kept by the Registrar in the name of the Nominee, but may be registered in whatever name or names Owners transferring or exchanging Bonds shall designate, in accordance with the provisions of this Indenture. (e) Notwithstanding any other provision of this Indenture to the contrary, so long as any Bond is registered in the name of the Nominee, all payments with respect to principal or purchase price of or, premium if any, and interest on such Bond and all notices with respect to such Bond shall be made and given, respectively, in the manner provided in the DTC Representation Letter. Owners shall have no lien or security interest in any rebate or refund paid by DTC to the Paying Agent which arises from the payment by the Paying Agent of principal of, or premium, if any, or interest on, the Bonds in immediately available funds to DTC. (f) So long as any Bond is held in book-entry form a Beneficial Owner (through its DTC Participant) shall give notice to the Trustee to elect to have its Bonds purchased, and shall effect delivery of such Bonds by causing such DTC Participant to transfer its interest in the Bonds equal -37- 43 to such Beneficial Owner's interest on the records of DTC to the Trustee's participant account with DTC. The requirement for physical delivery of the Bonds in connection with any purchase pursuant to Section 3.01 and Section 3.02 hereof shall be deemed satisfied when the ownership rights in the Bonds are transferred by DTC Participants on the records of DTC to the Trustee's participant account. SECTION 2.17. PAYMENTS PURSUANT TO THE CREDIT FACILITY. So long as the Credit Facility shall be in effect, the Trustee, Registrar and Paying Agent shall observe the following provisions respecting the Credit Facility: (a) If on the Business Day prior to each Interest Payment Date and prior to each date upon which the principal of the Bonds becomes due on the Maturity Date or pursuant to a mandatory redemption pursuant to Section 4.03 hereof, the Trustee has received actual notice that sufficient amounts will not be on deposit in the Bond Fund on such Interest Payment Date, Maturity Date or redemption date to pay the principal of or interest on the Bonds then maturing or subject to such mandatory redemption, or if the Trustee determines on any Interest Payment Date or on any date upon which the principal of the Bonds becomes due on the Maturity Date or pursuant to a mandatory redemption effected pursuant to Section 4.03 hereof that there are not sufficient funds in the Bond Fund to pay the principal of or interest on the Bonds coming due on such date, the Trustee shall so notify the Provider. Such notice shall specify the amount of the anticipated or actual deficiency, as the case may be, the Bonds to which such deficiency is applicable and whether such Bonds will be or are deficient as to principal or interest, or both. The Insurance Policy provides, in effect, that if the Trustee has not so notified the Provider at least one Business Day prior to an Interest Payment Date or prior to any date upon which the principal of the Bonds becomes due on the Maturity Date or pursuant to a mandatory redemption effected pursuant to Section 4.03 hereof, the Provider will make payments of principal or interest, or both, due on the Bonds on or before the first Business Day next following the date on which the Provider shall have received notice of nonpayment from the Trustee. Otherwise, such payments shall be made on such Interest Payment Date, Maturity Date or redemption date. (b) The Trustee shall, after giving notice to the Provider as provided in (a) above, make available to the Provider and, at the Provider's direction, to the Insurance Trustee, the registration books of the Issuer maintained by the Registrar, and all records relating to the Bond Fund and any other funds and accounts maintained under this Indenture. (c) The Trustee or the Registrar shall provide the Provider and the Insurance Trustee with a list of Owners entitled to receive principal or interest payments from the Provider under the terms of the Credit Facility, and shall make arrangements with the Insurance Trustee (i) to mail checks or drafts to the Owners entitled to receive full or partial interest payments from the Provider and (ii) to pay principal upon Bonds surrendered or, if a book-entry system is in effect, ownership interests in Bonds transferred to the Insurance Trustee by the Owners or Beneficial Owners entitled to receive full or partial principal payments from the Provider. -38- 44 (d) The Trustee shall, at the time it provides notice to the Provider pursuant to (a) above, notify the Owners entitled to receive the payment of principal thereof or interest thereon from the Provider (i) as to the fact of such entitlement, (ii) that the Provider will remit to them all or a part of the interest payments next coming due upon proof of the entitlement of such Owners to interest payments and delivery to the Insurance Trustee, in form satisfactory to the Insurance Trustee, of an appropriate assignment of the Owner's right to payment, (iii) that should they be entitled to receive full payment of principal from the Provider, they must surrender their Bonds (along with an appropriate instrument of assignment in form satisfactory to the Insurance Trustee to permit ownership of such Bonds to be registered in the name of the Provider) for payment to the Insurance Trustee, and not the Trustee or Paying Agent, and (iv) that should they be entitled to receive partial payment of principal from the Provider, they must surrender their Bonds for payment thereon first to the Paying Agent, which shall note on such Bonds the portion of the principal previously paid by the Paying Agent, and then, along with an appropriate instrument of assignment in form satisfactory to the Insurance Trustee, to the Insurance Trustee, which will then pay the unpaid portion of principal thereof. At any time that there is a DTC book-entry system in effect for the Bonds, the notice required pursuant to this Section 2.17 shall specify that, in lieu of surrendering the Bonds, the beneficial ownership interests to receive payment of such principal or interest shall be transferred on the records of DTC to the order of the Insurance Trustee. (e) In the event that the Trustee or Paying Agent has notice that any payment of principal of or interest on a Bond which has become Due for Payment and which is made to an Owner by or on behalf of the Issuer has been deemed a preferential transfer and theretofore recovered from such Owner pursuant to the United States Bankruptcy Code by a trustee in bankruptcy in accordance with the final, nonappealable order of a court having competent jurisdiction, the Trustee or Paying Agent shall, within five Business Days after it has notice that such payment has been deemed a preferential transfer, notify all Owners that in the event that any Owner's payment is so recovered, such Owner will be entitled to payment from the Provider to the extent of such recovery if sufficient funds are not otherwise available, and the Paying Agent shall furnish to the Provider its records evidencing the payments of principal of and interest on the Bonds which have been made by the Paying Agent and subsequently recovered from Owners and the dates on which such payments were made. (f) In addition to those rights granted the Provider under this Indenture, the Provider shall, to the extent it makes payment of principal of or interest on the Bonds, become subrogated to the rights of the recipients of such payments in accordance with the terms of the Credit Facility, and to evidence such subrogation (i) in the case of subrogation as to claims for past due interest, the Registrar shall note the Provider's rights as subrogee on the registration books of the Issuer maintained by the Registrar upon receipt from the Provider of proof of the payment of interest thereon to the Owners, and (ii) in the case of subrogation as to claims for past due principal, the Registrar shall note the Provider's rights as subrogee on the registration books of the Issuer maintained by the Registrar upon surrender of the Bonds by the Owners thereof, together with proof of the payment of principal thereof. -39- 45 SECTION 2.18. CHANGE OF CREDIT FACILITY. (a) The Trustee shall give notice by Mail of a proposed Change of Credit Facility pursuant to Section 4.07(a) of the Agreement to the Owners prior to a date upon which the Owners can give the requisite notice to tender their Bonds on or prior to the effective date of such Change of Credit facility. Such notice shall (a) describe the proposed Change of Credit Facility (subject to the Company's ability to rescind its election to make such Change of Credit Facility), (b) state the effective date of such Change of Credit Facility, and (c) state such other matters as the Company may direct. (b) The Trustee shall give notice by Mail of a proposed Change of Credit Facility pursuant to Section 4.07(b) of the Agreement to the Owners not less than 15 days prior to the effective date of such Change of Credit Facility. Such notice shall (a) describe the proposed Change of Credit Facility (subject to the Company's ability to rescind its election to make such Change of Credit Facility), (b) state the effective date of such Change of Credit Facility, (c) state that such Bonds are subject to mandatory purchase on or before such effective date pursuant to Section 3.02(a)(iii), (d) describe the procedures for such mandatory purchase and the date thereof, (e) state the purchase price of such Bonds on such effective date (expressed as a percentage of the principal amount thereof), (f) state that the Owners of such Bonds do not have the right to retain their Bonds on such effective date, and (g) state such other matters as the Company may direct. SECTION 2.19. CUSIP NUMBERS. The Issuer in issuing the Bonds may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Owners; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Bonds or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Bonds, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer or the Company will promptly notify the Trustee and the Registrar of any change in any CUSIP number(s). Neither the Issuer, the Registrar nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Bond, check, advice of payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Issuer, the Registrar nor the Trustee shall be liable for any inaccuracy in such matters.

SECTION 4.04. SELECTION OF BONDS FOR REDEMPTION. If less than all of the Bonds are called for redemption the Trustee shall select the Bonds or any given portion thereof to be redeemed, from the outstanding Bonds or such given portion thereof not previously called for redemption, by lot. For the purpose of any such selection the Trustee shall (to the extent practicable) assign a separate number for each minimum Authorized Denomination of each Bond of a denomination of more than such minimum; provided that, following any such selection, both the portion of such Bond to be redeemed and the portion remaining shall be in Authorized Denominations. The Trustee shall promptly notify the Issuer and the Company in writing of the numbers of the Bonds or portions thereof so selected for redemption. SECTION 4.05. NOTICE OF REDEMPTION. -48- 54 (a) The Trustee, for and on behalf of the Issuer, shall give notice of the redemption of any Bond by Mail, postage prepaid, not less than fifteen (15) nor more than sixty (60) days prior to the redemption date, to the Owner of such Bond at the address shown on the registration books of the Registrar on the date such notice is mailed and to any Auction Agent, any Remarketing Agent, any Provider, Moody's, S&P, the Securities Depositories and one or more of the Information Services.

Notice of redemption to the Securities Depositories and the Information Services shall be given by registered mail. Each notice of redemption shall state the date of such notice, the date of issue of the Bonds to be redeemed, the redemption date, the redemption price, the place of redemption (including the name and appropriate address or addresses of the Paying Agent), the source of the funds to be used for such redemption, the principal amount, the CUSIP number (if any) of the maturity and, if less than all, the distinctive certificate numbers of the Bonds to be redeemed and, in the case of Bonds to be redeemed in part only, the respective portions of the principal amount thereof to be redeemed. Each such notice shall also state that the interest on the Bonds designated for redemption shall cease to accrue from and after such redemption date and that on said date there will become due and payable on each of said Bonds the principal amount thereof to be redeemed, interest accrued thereon, if any, to the redemption date and the premium, if any, thereon (such premium to be specified) and shall require that such Bonds be then surrendered at the address or addresses of the Paying Agent specified in the redemption notice. Notwithstanding the foregoing, failure by the Trustee to give notice pursuant to this Section 4.05 to any one or more of the Information Services or Securities Depositories or the insufficiency of any such notices shall not affect the sufficiency of the proceedings for redemption. Failure to give any required notice of redemption as to any particular Bond shall not affect the validity of the call for redemption of any Bonds in respect of which no such failure has occurred. (b) With respect to any notice of optional redemption of Bonds in accordance with Section 4.02 hereof, unless, upon the giving of such notice, such Bonds shall be deemed to have been paid within the meaning of Article VIII hereof, such notice may state that such redemption is conditioned upon the receipt by the Trustee, on or prior to the date fixed for such redemption, of moneys sufficient to pay the principal of, and premium, if any, and interest on, such Bonds to be redeemed. In the event such moneys are not so received, the redemption shall not be made and the Trustee shall within a reasonable time thereafter give notice, in the manner in which the notice of redemption was given, that such redemption will not take place. (c) The Trustee shall also provide the notice with respect to the Bonds to be redeemed as required by Section 3.05(a) hereof. SECTION 4.06. PARTIAL REDEMPTION OF BONDS. Upon surrender of any Bond redeemed in part only, the Registrar shall exchange the Bond redeemed for a new Bond of like tenor and in an Authorized Denomination without charge to the Owner in the principal amount of the portion of the Bond not redeemed. In the event of any partial redemption of a Bond which is registered in the name of Cede & Co., DTC may elect to make a notation on the Bond certificate which reflects the date and amount of the reduction in the principal amount of said Bond in lieu of surrendering the Bond certificate to the Registrar for exchange. The Issuer, the Company and the -49- 55 Trustee shall be fully released and discharged from all liability to the extent of payment of the redemption price for such partial redemption. SECTION 4.07. NO PARTIAL REDEMPTION AFTER DEFAULT. Anything in this Indenture to the contrary notwithstanding, if there shall have occurred and be continuing an Event of Default (other than an Event of Default described in Section 9.0l(d) hereof) of which an authorized officer of the corporate trust department of the Trustee has actual knowledge, there shall be no redemption of less than all of the Bonds at the time Outstanding. SECTION 4.08. PAYMENT OF REDEMPTION PRICE. For the redemption of any of the Bonds, the Issuer shall cause to be deposited in the Bond Fund, solely out of the Revenues and any other moneys constituting the Trust Estate, an amount sufficient to pay the principal of, and premium, if any, and interest to become due on, the Bonds called for redemption on the date fixed for such redemption. The obligation of the Issuer to cause any such deposit to be made hereunder shall be reduced by the amount of moneys in the Bond Fund or any fund in Article VIII hereof available for and used on such redemption date for payment of the principal of, and premium, if any, and accrued interest on, the Bonds to be redeemed. The Trustee shall apply amounts as and when required available therefor in the Bond Fund to pay principal of, and premium, if any, and interest on, the Bonds. SECTION 4.09. EFFECT OF REDEMPTION. Notice of redemption having been duly given as aforesaid, and moneys for payment of the redemption price being held by the Trustee if such redemption was conditioned thereon, the Bonds so called for redemption shall, on the redemption date designated in such notice, become due and payable at the redemption price specified in such notice, interest on the Bonds so called for redemption shall cease to accrue, said Bonds shall cease to be entitled to any lien, benefit or security under this Indenture, and the Owners of said Bonds shall have no rights in respect thereof except to receive payment of the redemption price thereof, without interest accrued on any funds held to pay such redemption price accruing after the date of redemption.

Each such certificate or telephonic advice shall contain a statement that each investment so designated by the Company constitutes an Investment Security and can be made without violation of any provision hereof or of the Agreement or of the Tax Certificate.

ARTICLE VIII DEFEASANCE If the Issuer shall pay or cause to be paid to the Owner of any Bond secured hereby the principal of, and premium, if any, and interest due and payable, and thereafter to become due and payable, upon such Bond or any portion of such Bond in an Authorized Denomination thereof, such Bond or portion thereof shall cease to be entitled to any lien, benefit or security under this Indenture. If the Issuer shall pay or cause to be paid the principal of, and premium if any, and interest due and payable on, all Outstanding Bonds, and thereafter to become due and payable thereon, and shall pay or cause to be paid all other sums payable hereunder by the Issuer, including any necessary and proper fees, compensation and expenses of the Trustee, the Paying Agent, the Registrar, the Provider and the Remarketing Agent, then, and in that case, the right, title and interest of the Trustee in and to the Trust Estate shall thereupon cease, terminate and become void.

The Trustee may conclusively rely on certificates of the Remarketing Agent and the Provider as to the amount of any fees, expenses and other amounts owing to them. Notwithstanding anything herein to the contrary, in the event that the principal of and interest due on any Bonds shall be paid by the Provider pursuant to the Credit Facility, such Bonds shall remain Outstanding for all purposes, shall not be defeased or otherwise satisfied and shall not be considered paid by the Issuer, and the assignment and pledge of the Trust Estate and all covenants, agreements and other obligations of the Issuer to such Owners shall continue to exist and shall run to the benefit of the Provider and the Provider shall be subrogated to the rights of such Owners. All or any portions of Bonds (in Authorized Denominations) shall, prior to the maturity or redemption date thereof, be deemed to have been paid within the meaning of this Article VIII and for all purposes of this Indenture when: (a) in the event said Bonds or portions thereof have been selected for redemption in accordance with Section 4.04 hereof, the Trustee shall have given, or the Company shall have given to the Trustee in form satisfactory to it irrevocable instructions to give, on a date in accordance with the provisions of Section 4.05 hereof, notice of redemption of such Bonds or portions thereof; (b) there shall have been deposited with the Trustee moneys in an amount sufficient (without relying on any investment income) to pay when due the principal of, and premium, if any, and interest due and to become due (which amount of interest to become due shall be calculated at the Maximum Interest Rate unless the interest rate borne by all of such Bonds is not subject to adjustment prior to the maturity or redemption thereof, in which case the amount of interest shall be calculated at the rate borne by such Bonds) on said Bonds or portions thereof on and prior to the redemption date or maturity date thereof, as the case may be; (c) in the event said Bonds or portions thereof do not mature and are not to be redeemed within the next succeeding 60 days, the Issuer at the direction of the Company shall have given the Trustee in form satisfactory to it irrevocable instructions to give, as soon as practicable in the same manner as a notice of redemption is given pursuant to Section 4.05 hereof, a notice to the Owners of said Bonds or portions thereof and to the Provider that the deposit required by clause (b) above has been made with the Trustee and that said Bonds or portions thereof are deemed to have been paid in accordance with this Article VIII and stating the maturity or redemption date upon which moneys are to be available for the payment of the principal of, and premium, if any, and interest on, said Bonds or portions thereof; and (d) the Trustee shall have received a Favorable Opinion of Bond Counsel with respect to such deposit. In the event the requirements of the next succeeding paragraph can be satisfied, the preceding paragraph shall not apply, and the following two paragraphs shall be applicable. -58- 64 Any Bond shall be deemed to be paid within the meaning of this Article VIII and for all purposes of this Indenture when: (a) payment of the principal of and premium if any, on such Bond, plus interest thereon to the due date thereof (whether such due date is by reason of maturity or acceleration or upon redemption as provided herein) either (A) shall have been made or caused to be made in accordance with the terms thereof or (B) shall have been provided for by irrevocably depositing with the Trustee in trust and irrevocably set aside exclusively for such payment (1) moneys sufficient to make such payment, and/or (2) Government Obligations maturing as to principal and interest in such amount and at such time as will insure, without reinvestment, the availability of sufficient moneys to make such payment; (b) all necessary and proper fees, compensation and expenses of the Issuer, the Trustee, the Remarketing Agent, the Provider, the Paying Agent and the Registrar pertaining to the Bonds with respect to which such deposit is made shall have been paid or the payment thereof provided for to the satisfaction of the Trustee, the Trustee being able to conclusively rely on certificates of the Remarketing Agent and the Provider as to the amount of any fees, compensation and expenses owing to them; and (c) an opinion of an independent public accountant of nationally recognized standing, selected by the Company, to the effect that such moneys and/or Government Obligations will insure, without reinvestment, the availability of sufficient moneys to make such payment, and a Favorable Opinion of Bond Counsel with respect to such deposit shall have been delivered to the Trustee. At such times as a Bond shall be deemed to be paid hereunder, as aforesaid, such Bond shall no longer be secured by or entitled to the benefits of this Indenture, except for the purposes of registration and exchange of Bonds and of any such payment from such moneys or Government Obligations. The foregoing provisions of this paragraph shall apply only if (x) such Bond is to mature or be called for redemption prior to the next date upon which such Bond is subject to purchase pursuant to Section 3.01 and 3.02 hereof; and (y) the Company has waived, to the satisfaction of the Trustee, its right to convert the interest rate borne by such Bond. No deposit under clause (a)(B) of the preceding paragraph shall be deemed a payment of such Bonds as aforesaid until: (i) proper notice of redemption of such Bonds shall have been previously given in accordance with Section 4.05 hereof, or in the event said Bonds are not to be redeemed within the next succeeding 60 days, until the Company shall have given the Trustee on behalf of the Issuer, in form satisfactory to the Trustee, irrevocable instructions to notify, as soon as practicable, the Owners of the Bonds and the Provider in accordance with Section 4.05 hereof, that the deposit required by clause (a)(B) above has been made with the Trustee and that said Bonds are deemed to have been paid in accordance with this Article VIII and stating the maturity or redemption date upon which moneys are to be available for the payment of the principal of and the applicable redemption premium, if any, on said Bonds, plus interest thereon to the due date thereof; or (ii) the maturity of such Bonds. -59- 65 Moneys deposited with the Trustee pursuant to this Article VIII shall not be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of, premium, if any, and interest on said Bonds or portions thereof, or for the payment of the purchase price of Bonds in accordance with Section 3.03 hereof; provided that such moneys, if not then needed for such purpose, shall to the extent practicable, be invested and reinvested in Government Obligations maturing on or prior to the earlier of (i) the date moneys may be required for the purchase of Bonds pursuant to Section 3.03 hereof or (ii) the Interest Payment Date next succeeding the date of investment or reinvestment, and interest earned from such investments shall be paid over to the Company, as received by the Trustee, free and clear of any trust, lien or pledge. If payment of less than all the Bonds is to be provided for in the manner and with the effect provided in this Article VIII, the Trustee shall select such Bonds or portion of such Bonds in the manner specified by Section 4.04 hereof for selection for redemption of less than all Bonds in the principal amount, not less than $100,000 or, to the extent permitted by Section 4.01(b) hereof, $5,000, designated to the Trustee by the Company. Notwithstanding that all or any portion of the Bonds are deemed to be paid within the meaning of this Article VIII, the provisions of this Indenture relating to (i) the registration and exchange of Bonds, (ii) the delivery of Bonds to the Trustee for purchase and the related obligations of the Trustee with respect thereto, (iii) replacement of mutilated, lost, destroyed or stolen Bonds, (iv) payment of the Bonds from the moneys deposited as described in this Article and (v) payment, compensation, reimbursement and indemnification of the Trustee, shall remain in full force and effect with respect to all Bonds until the Maturity Date or the last date fixed for redemption of all Bonds prior to maturity and, in the case of clause (v), until payment, compensation, reimbursement or indemnification, as the case may be, of the Trustee.

If on the date on which payment of principal of, interest on or other amount in any respect of the Bonds is due, sufficient moneys are not available to make such payment, the Trustee shall promptly give telephonic notice of such insufficiency to the Company given to the person at the telephone number provided for in Section 3.06(c) hereof.

(b) The provisions of Section 9.02(a) are subject further to the condition that if, after the principal of the Bonds shall have been so declared to be due and payable and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall cause to be deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all Bonds, any unpaid purchase price and the principal of any and all Bonds which shall have become due otherwise than by reason of such declaration -61- 67 (with interest upon such principal and, to the extent permissible by law, on overdue installments of interest, at the rate per annum then borne by the Bonds) and such amount as shall be sufficient to cover reasonable compensation and reimbursement of expenses payable to the Trustee and all Events of Default (other than nonpayment of the principal of Bonds which shall have become due by said declaration) shall have been remedied, then, in every such case, such Event of Default shall be deemed waived and such declaration and its consequences rescinded and annulled, and the Trustee shall promptly give written notice of such waiver, rescission or annulment to the Issuer and the Company, and shall give notice thereof by Mail to all Owners of Outstanding Bonds; provided, however, that no such waiver, rescission and annulment shall extend to or affect any other Event of Default or subsequent Event of Default or impair any right, power or remedy consequent thereon. (c) Upon the occurrence and continuance of any Event of Default, then and in every such case the Trustee in its discretion, with the consent of the Provider (unless a Provider Default shall have occurred and be continuing) may, and upon the written request of the Owners of not less than 33-1/3% in principal amount of the Bonds then Outstanding and receipt of indemnity to its satisfaction (except against negligence or willful misconduct) shall in its own name and as the Trustee of an express trust: (i) by mandamus, or other suit, action or proceeding at law or in equity, enforce all rights of the Owners under, and require the Issuer, the Company or the Provider to carry out any agreements with or for the benefit of the Owners of Bonds and to perform its or their duties under, the Act, the Agreement, this Indenture, the Credit Facility and the Credit Facility Agreement, provided that any such remedy may be taken only to the extent permitted under the applicable provisions of the Agreement or this Indenture, as the case may be; (ii) bring suit upon the Bonds; (iii) by action or suit in equity require the Issuer to account as if it were the trustee of an express trust for the Owners of Bonds; or (iv) by action or suit in equity enjoin any acts or things which may be unlawful or in violation of the rights of the Owners of Bonds.

(d) The Trustee shall waive any Event of Default hereunder and its consequences and rescind any declaration of acceleration of principal upon (i) the written direction of the Provider (unless a Provider Default shall have occurred and be continuing) and (ii) the written request of the Owners of (A) more than a majority in principal amount of all Outstanding Bonds in respect -62- 68 of which default in the payment of principal or purchase price of or interest on the Bonds exists or (B) more than a majority in principal amount of all Outstanding Bonds in the case of any other Event of Default; provided, however, that (x) there shall not be waived any Event of Default specified in Section 9.01(a), Section 9.01(b) or Section 9.01(c) hereof unless prior to such waiver or rescission the Issuer shall have caused to be deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all Bonds and the principal and purchase price of any and all Bonds which shall have become due otherwise than by reason of such declaration of acceleration (with interest upon such principal and, to the extent permissible by law, on overdue installments of interest, at the rate per annum then borne by the Bonds) and (y) no Event of Default shall be waived unless (in addition to the applicable conditions as aforesaid) there shall have been deposited with the Trustee such amount as shall be sufficient to cover reasonable compensation and reimbursement of expenses payable to the Trustee. In case of any waiver or rescission described above, or in case any proceeding taken by the Trustee on account of any such Event of Default shall have been discontinued or concluded or determined adversely, then and in every such case the Issuer, the Trustee and the Owners of Bonds shall be restored to their former positions and rights hereunder, respectively; provided further that no such waiver or rescission shall extend to any subsequent or other Event of Default, or impair any right consequent thereon. SECTION 9.03. RESTORATION TO FORMER POSITION. In the event that any proceeding taken by the Trustee to enforce any right under this Indenture shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then the Issuer, the Trustee and the Owners of Bonds shall be restored to their former positions and rights hereunder, respectively, and all rights, remedies and powers of the Trustee shall continue as though no such proceeding had been taken. SECTION 9.04. OWNERS' RIGHT TO DIRECT PROCEEDINGS. Anything in this Indenture to the contrary notwithstanding, upon the occurrence and continuance of an Event of Default, the Provider (provided that a Provider Default shall not have occurred and be continuing) or the Owners of a majority in principal amount of the Bonds then Outstanding, with the consent of the Provider (if no Provider Default shall have occurred and be continuing), shall have the right, by an instrument in writing executed and delivered to the Trustee and upon furnishing to the Trustee indemnity satisfactory to it (except against negligence or willful misconduct), to direct the time, method and place of conducting all remedial proceedings available to the Trustee under this Indenture or exercising any trust or power conferred on the Trustee by this Indenture, provided that such direction shall not be other than in accordance with the provisions of law, the Agreement and this Indenture and shall not result in any personal liability of the Trustee.

SECTION 9.10. APPLICATION OF MONEYS. Any moneys received by the Trustee, by any receiver or by any Owner pursuant to any right given or action taken under the provisions of this Article IX, after payment of the costs and expenses, liabilities and advances incurred or made by the Trustee or its agents or counsel (provided that moneys held for Bonds not presented for -64- 70 payment or deemed paid pursuant to Section 3.06(d), Section 6.04 or Article VIII hereof shall not be used for purposes other than payment of such Bonds), shall be deposited in the Bond Fund and all moneys so deposited in the Bond Fund during the continuance of an Event of Default (other than moneys for the payment of Bonds which had matured or otherwise become payable prior to such Event of Default or for the payment of interest due prior to such Event of Default) shall be applied as follows: (a) Unless the principal of all the Bonds shall have been declared due and payable, all such moneys shall be applied (i) first, to the payment to the persons entitled thereto of all installments of interest then due on each Bond, with interest on overdue installments of interest, if lawful at the rate per annum then borne by such Bond, in the order of maturity of the installments of such interest and, if the amount available shall not be sufficient to pay in full any particular installment of interest, then to the payment ratably, according to the amounts due on such installment, and (ii) second, to the payment to the persons entitled thereto of the unpaid principal of any of the Bonds which shall have become due (other than Bonds called for redemption for the payment of which money is held pursuant to the provisions of this Indenture) with interest on each Bond at its rate from the respective dates upon which it became due and, if the amount available shall not be sufficient to pay in full Bonds due on any particular date, together with such interest, then to the payment ratably, according to the amount of principal and interest due on such date, in each case to the persons entitled thereto, without any discrimination or privilege.

In the Agreement, the Company has agreed that it will pay to the Trustee, the Paying Agent, and the Registrar compensation and reimbursement of expenses and advances and certain indemnitees, but the Company may, without creating an Event of Default, contest in good faith the reasonableness of any such expenses and advances. If the Company shall have failed to make any payment to the Trustee, the Paying Agent or the Registrar under the Agreement, then each of the Trustee, the Paying Agent and the Registrar shall have, in addition to any other rights hereunder, a claim, prior to the claim of the Owners, for the payment of their compensation and -67- 73 indemnitees and the reimbursement of their expenses and any advances made by them, as provided in this Section 10.04, upon the moneys and obligations in the Bond Fund, except for moneys or obligations deposited with or paid to the Trustee for the redemption or payment of Bonds which are deemed to have been paid in accordance with Article VIII hereof, or funds held pursuant to Section 6.04 hereof. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 7.01(c) of the Agreement, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. The provisions of this Section 10.04 shall survive the termination of this Indenture. SECTION 10.05. NOTICE OF EVENTS OF DEFAULT AND DETERMINATION OF TAXABILITY. The Trustee shall not be required to take notice, or be deemed to have notice of any default or Event of Default, other than an Event of Default under Section 9.01(a), Section 9.01(b) or Section 9.01(c) hereof or any Provider Default, unless the Trustee shall have been specifically notified in writing at the Principal Office of the Trustee, Attention: Corporate Trust Administration, of such Event of Default or Provider Default by the Owners of at least 25% in principal amount of the Bonds then Outstanding, the Issuer, the Company, the Provider or the Remarketing Agent. The Trustee may, however, at any time, in its discretion, require of the Issuer full information and cooperation as to the performance of any of the covenants, conditions and agreements contained herein. Such inquiry shall not for the purposes of this Section 10.05 constitute notice of any Event of Default. The Issuer shall not be required to take notice, or be deemed to have notice, of any Event of Default, other than an Event of Default of which it shall have actual knowledge. If an Event of Default occurs after the Trustee has notice of the same as provided in this Section 10.05, or if a Determination of Taxability occurs of which the Trustee has actual knowledge, then the Trustee shall give notice thereof by Mail to the Provider, the Remarketing Agent and the Owners of Outstanding Bonds. SECTION 10.06. ACTION BY TRUSTEE. Except as provided in Section 3.03, Section 9.02 and Section 9.04 hereof and except for the payment of principal of, and premium, if any, and interest on, the Bonds when due from moneys held by the Trustee as part of the Trust Estate, the Trustee shall be under no obligation to take any action in respect of any Event of Default or toward the execution or enforcement of any of the trusts hereby created, or to institute, appear in or defend any suit or other proceeding in connection therewith, unless requested in writing so to do by the Owners of at least 33-1/3% in principal amount of the Bonds then Outstanding and, if in its opinion such action may tend to involve it in expense or liability, unless furnished, from time to time as often as it may require, with security and indemnity satisfactory to it (except against negligence or willful misconduct); but the foregoing provisions are intended only for the protection of the Trustee, and shall not affect any discretion or power given by any provisions of this Indenture to the Trustee to take action in respect of any Event of Default without such notice or request from the Owners, or without such security or indemnity. -68- 74 Notwithstanding any other provision of this Indenture, in determining whether the rights of the Owners will be adversely affected by any action taken pursuant to the terms and provisions of this Indenture, the Trustee shall consider the effect on the Owners as if there were no Credit Facility. SECTION 10.07. GOOD-FAITH RELIANCE. The Trustee, the Registrar, the Provider and the Remarketing Agent, shall be protected and shall incur no liability in acting or proceeding in good faith upon any resolution, notice, telegram, telex or facsimile transmission, request, consent, waiver, certificate, statement, affidavit, voucher, bond, requisition or other paper or document which it shall in good faith believe to be genuine and to have been passed or signed by the proper board, body or person or to have been prepared and furnished pursuant to any of the provisions of this Indenture or the Agreement, or upon the written opinion of any attorney, engineer, accountant or other expert believed, without independent investigation, by the Trustee, the Registrar or the Remarketing Agent, as the case may be, to be qualified in relation to the subject matter. The Trustee, the Registrar, the Provider and the Remarketing Agent, shall be under no duty to make any investigation or inquiry as to any statements contained or matters referred to in any such instrument, but may accept and rely upon the same as conclusive evidence of the truth and accuracy of such statements; provided, however, that the Trustee may, in its discretion, make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation it shall be entitled to examine the books, records and premises of the Company personally or by agent or attorney. Neither the Trustee, the Registrar, the Provider nor the Remarketing Agent shall be bound to recognize any person as an Owner or to take any action at such person's request unless satisfactory evidence of the ownership of such Bond shall be furnished to such entity. Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of negligence or bad faith on its part, request and conclusively rely upon a certificate of an Authorized Company Representative or an Executive Officer. The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder. Notwithstanding anything elsewhere in this Indenture contained, the Trustee shall have the right, but shall not be required, to demand, in respect of the authentication of any Bonds or the taking of any other action whatsoever within the purview of this Indenture or the Agreement, any showings, certificates, opinions or other information, or corporate action or evidence thereof, in addition to those by the terms hereof or thereof required as a condition of such action which are reasonably deemed desirable by the Trustee for the purpose of establishing the right of the Issuer or the Company to request the taking of such action by the Trustee. SECTION 10.08. DEALINGS IN BONDS; ALLOWANCE OF INTEREST. The Trustee, the Registrar, the Provider, or the Remarketing Agent, in its individual capacity, may in good faith buy, sell own, -69- 75 hold and deal in any of the Bonds issued hereunder and may join in any action which any Owner may be entitled to take with like effect as if it did not act in any capacity hereunder. The Trustee, the Registrar, the Provider, or the Remarketing Agent, in its individual capacity, either as principal or agent, may also engage in or be interested in any financial or other transaction with the Issuer or the Company, and may act as depositary, trustee or agent for any committee or body of Owners secured hereby or other obligations of the Issuer or the Company as freely as if it did not act in any capacity hereunder. All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received hereunder except such as it may agree with the Company to pay thereon. SECTION 10.09. SEVERAL CAPACITIES. Anything in this Indenture to the contrary notwithstanding, the same entity may serve hereunder as the Trustee, the Registrar, the Paying Agent and the Remarketing Agent and in any other combination of such capacities, to the extent permitted by law. For purposes of this Trust Indenture, the Remarketing Agent shall not be deemed to be an agent or representative of the Trustee. SECTION 10.10. RESIGNATION OF TRUSTEE. The Trustee may resign and be discharged of the trusts created by this Indenture by executing any instrument in writing resigning such trust and specifying the date when such resignation shall take effect, and filing the same with the Issuer, the Company, the Registrar, the Provider, and the Remarketing Agent not less than 45 days before the date specified in such instrument when such resignation shall take effect, and by giving notice of such resignation by Mail not less than three weeks prior to such resignation date, to all Owners of Bonds.

In case at any time the Trustee shall be removed, or be dissolved, or if its property or affairs shall be taken under the control of any state or federal court or administrative body because of insolvency or bankruptcy, or for any other reason, then a vacancy shall forthwith and ipso facto exist in the office of Trustee and a successor may be appointed, and in case at any time the Trustee shall resign, then a successor may be appointed by filing with the Issuer, the Company, the Registrar and the Remarketing Agent an instrument in writing executed by (i) the Provider, if no Provider Default shall have occurred and be continuing, or (ii) the Owners of not less than a majority in principal amount of the Bonds then Outstanding and, if no Provider Default shall have occurred and be continuing, the Provider, or (iii) the Company if no default or Event of Default is then existing under Section 7.01 of the Agreement or Section 9.01(a), (b) or (c) of this Indenture.

After any appointment by the Issuer, it shall cause notice of such appointment to be given to the Remarketing Agent and the Registrar and to be given by Mail to all Owners of Bonds.

Any successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuer an instrument accepting such appointment hereunder, and thereupon such successor Trustee, without any further act, deed or conveyance, shall become duly vested with all the estates, property rights, powers, trusts, duties and obligations of its predecessor in the trust hereunder, with like effect as if originally named Trustee herein.

Upon the resignation or removal of the Registrar, the Company shall appoint a new Registrar. In the event of the resignation or removal of the Registrar, the Registrar shall deliver any Bonds held by it in such capacity to its successor or, if there be no successor, to the Trustee. In the event that the Company shall fail to appoint a Registrar hereunder, or in the event that the Registrar shall resign or be removed, or be dissolved, or if the property or affairs of the Registrar shall be taken under the control of any state or federal court or administrative body because of bankruptcy or insolvency, or for any other reason, and the Company shall not have appointed its successor as Registrar, the Trustee shall ipso facto be deemed to be the Registrar for all purposes of this Indenture until the appointment by the Company of the Registrar or successor Registrar, as the case may be.

It shall be the duty of the Trustee to make such arrangements with any such paying agent as may be necessary to assure, to the extent of the moneys held by the Trustee for such payment, the prompt payment of the principal of, and premium, if any, and interest on, the Bonds presented at either place of payment. The Paying Agent initially appointed hereunder is the Trustee, and the place of payment shall be the Delivery Office of the Trustee. -74- 80 SECTION 10.24. ADDITIONAL DUTIES OF TRUSTEE. The Trustee shall: (a) hold all Bonds delivered to it hereunder for the account of and for the benefit of the respective Owners which shall have so delivered such Bonds pursuant to Section 3.01 or Section 3.02 until moneys representing the purchase price of such Bonds shall have been delivered to or for the account of or to the order of such Owners; (b) hold all moneys delivered to it hereunder for the purchase of Bonds for the benefit of the person or entity which shall have so delivered such moneys until the Bonds purchased with such moneys shall have been delivered to or for the account of such person or entity; (c) keep such books and records with respect to the Bonds as shall be consistent with prudent industry practice and to make such books and records available for inspection by the Issuer, any Paying Agent, the Company and the Remarketing Agent at all reasonable times; and (d) as long as a book-entry system is in effect for the Bonds, the Trustee will comply with the DTC Representation Letter and perform all duties required of it thereunder.

(b) The ownership of Bonds shall be proved by the registration books kept under the provisions of Section 2.12 hereof. -75- 81 Nothing contained in this Article XI shall be construed as limiting the Trustee to such proof, it being intended that the Trustee may accept any other evidence of matters herein stated which it may deem sufficient. Any request by or consent of any Owner shall bind every future Owner of the same Bond or any Bond or Bonds issued in lieu thereof or upon registration of transfer thereof in respect of anything done by the Trustee or the Issuer in pursuance of such request or consent.

The Bonds are also subject to mandatory purchase during any Term Interest Rate Period on a day that the Bonds would be subject to optional redemption pursuant to Section 4.02(b)(iv) of the Indenture, at a purchase price equal to 100% the principal amount thereof plus an amount equal to any premium which would have been payable on such redemption date had the Bonds been redeemed if the Company gives notice to the Trustee on or before the Business Day prior to the redemption date that it elects to have the Bonds purchased in lieu of redemption. If the Bonds are purchased on or prior to the Record Date, the purchase price shall include accrued interest from the Interest Payment Date next preceding the date of purchase to the date of purchase (unless the date of purchase shall be an Interest Payment Date, in which case the purchase price shall be equal to the amount specified in the preceding sentence). If the Bonds are purchased after the Record Date, the purchase price shall not include accrued interest. BY ACCEPTANCE OF THIS BOND, THE REGISTERED OWNER HEREBY AGREES THAT, IF THIS BOND IS TO BE PURCHASED AND IF MONEYS SUFFICIENT TO PAY THE PURCHASE PRICE SHALL BE HELD BY THE TRUSTEE ON THE DATE THIS BOND IS TO BE PURCHASED, THIS BOND A-7 98 SHALL BE DEEMED TO HAVE BEEN PURCHASED AND SHALL BE PURCHASED ACCORDING OF THE INDENTURE, WHETHER OR NOT THIS BOND SHALL HAVE BEEN DELIVERED TO THE TRUSTEE, AND THE OWNER OF THIS BOND SHALL HAVE NO CLAIM HEREON, UNDER THE INDENTURE OR OTHERWISE, FOR ANY AMOUNT OTHER THAN THE PURCHASE PRICE HEREOF. The Bonds shall be redeemed in whole or in part, and if in part by lot, at any time at a redemption price equal to the principal amount thereof plus accrued interest to the redemption date upon receipt by the Trustee of a written notice from the Company stating that any of the following events has occurred and that the Company therefore intends to exercise its option to prepay the payments due under the Loan Agreement in whole or in part and thereby effect the redemption of Bonds in whole or in part to the extent of such prepayments: (a) the Company shall have determined or concurred in a determination that the continued operation of the Plant is impracticable, uneconomical or undesirable for any reason; (b) all or substantially all of the Plant shall have been condemned or taken by eminent domain; (c) the operation of the Plant shall have been enjoined or shall have otherwise been prohibited by, or shall conflict with, any order, decree, rule or regulation of any court or of any federal, state or local regulatory body, administrative agency or other governmental body; (d) unreasonable burdens or excessive liabilities shall have been imposed upon the Company in respect of all or a part of the Pollution Control Facilities or the Plant including, without limitation, federal, state or other ad valorem, property, income or other taxes not being imposed on the date of the Loan Agreement, as well as any statute or regulation enacted or promulgated after the date of the Loan Agreement that prevents the Company from deducting interest in respect of the Agreement for federal income tax purposes; or (e) all or substantially all of the Project shall be transferred or sold to any entity other than an affiliate of the Company; provided, however, that in the case of a redemption under this paragraph, the redemption price of the Bonds shall be equal to 101% of the principal amount thereof, plus accrued interest to the date of redemption, unless a smaller or no premium would be due upon optional redemption of the Bonds as described in the following paragraph. The Bonds shall be subject to redemption upon prepayment of the Loan Payments at the option of the Company, in whole, or in part by lot, prior to their maturity, as follows: (a) While the Bonds bear interest at a PARS Rate, the Bonds shall be subject to such redemption on the date next succeeding the last day of any PARS Rate Period at a redemption price equal to 100% of the principal amount thereof plus accrued interest, if any, to the redemption date. (b) While the Bonds bear interest at a Flexible Interest Rate or Rates, each Bond shall be subject to such redemption on the day next succeeding the last day of each Flexible Segment for such Bond at a redemption price equal to 100% of the principal amount thereof. (c) While the Bonds bear interest at a Daily Interest Rate or a Weekly Interest Rate, the Bonds shall be subject to such redemption on any Business Day at a redemption price equal to 100% of the principal amount thereof, plus accrued interest, if any, to the redemption date. A-8 99 (d) While the Bonds bear interest at a Term Interest Rate, the Bonds shall be subject to such redemption (1) on the day next succeeding the last day of each Term Interest Rate Period at a redemption price equal to the principal amount of the Bonds being redeemed plus accrued interest, if any, to the redemption date and (2) either (i) on the redemption dates and at the redemption prices specified by the Company pursuant to the next succeeding paragraph or (ii) during the redemption periods specified below, in each case in whole or in part, at the redemption prices (expressed as percentages of principal amount) hereinafter indicated plus accrued interest, if any, to the redemption date: LENGTH OF TERM INTEREST RATE PERIOD REDEMPTION DATES AND PRICES -------------------- --------------------------- Greater than or equal to 11 At any time on or after the first day of years the calendar month following the tenth anniversary of the effective date at 102% declining 1% annually to 100% Less than 11 years Not redeemable With respect to any Term Interest Rate Period, the Company may specify in a notice given to the Trustee redemption provisions, prices and periods other than those set forth above; provided, however, that such notice shall be accompanied by a Favorable Opinion of Bond Counsel to the effect that the proposed action is not prohibited by the laws of the State and the Indenture and will not adversely affect the Tax-Exempt status of the Bonds. The Bonds shall be redeemed in whole on any date from amounts which are to be prepaid by the Company under the Loan Agreement, at a redemption price equal to 100% of the principal amount thereof plus interest accrued, if any, to the redemption date within 180 days after the occurrence of a Determination of Taxability; provided that if, in the Favorable Opinion of Bond Counsel delivered to the Trustee, the redemption of a specified portion of the Bonds outstanding would have the result that interest payable on the Bonds remaining outstanding after such redemption would remain Tax-Exempt, then the Bonds shall be redeemed in part by lot (in Authorized Denominations), in such amount as Bond Counsel in such opinion shall have determined is necessary to accomplish that result. A "Determination of Taxability" shall be deemed to have occurred if as a result of the Company's failure to observe any covenant, agreement or representation in the Loan Agreement, a final decree or judgment of any federal court or a final action of the Internal Revenue Service determines that interest paid or payable on any Bond is or was includible in the gross income of an Owner of the Bonds for federal income tax purposes under the Code (other than an Owner who is a "substantial user" or "related person" within the meaning of Section 103(b)(13) of the 1954 Code. However, no such decree or action will be considered final for this purpose unless the Company has been given written notice and, if it is so desired and is legally allowed, has been afforded the opportunity to contest the same, either directly or in the name of any Owner of a Bond, and until conclusion of any appellate review, if sought. A-9 100 Notice of any optional or mandatory redemption shall be given by first-class mail not less than 15 days nor more than 60 days prior to the date fixed for redemption to the Owners of Bonds at the address shown on the registration books of the Registrar on the date such notice is mailed. If less than all of the Bonds are called for redemption, the Trustee shall select the Bonds or any given portion thereof from the outstanding Bonds or such given portion thereof not previously called for redemption, by lot. For the purpose of any such selection the Trustee shall assign a separate number for each minimum Authorized Denomination of each Bond of a denomination of more than such minimum; provided that, following any such selection, both the portion of such Bond to be redeemed and the portion remaining shall be in Authorized Denominations. Subject to the limitations and upon payment of the charges, if any, provided in the Indenture, Bonds may be exchanged at the Principal Office of the Registrar for a like aggregate principal amount of Bonds of the same tenor and of Authorized Denominations. This Bond is transferable by the person in whose name it is registered, in person, or by its attorney duly authorized in writing, at the Principal Office of the Registrar, but only in the manner, subject to the limitations and upon payment of the charges provided in the Indenture, and upon surrender and cancellation of this Bond accompanied by a written instrument of transfer in a form approved by the Registrar, duly executed. Upon such transfer a new fully registered Bond or Bonds in Authorized Denominations, for the same aggregate principal amount, will be issued to the transferee in exchange therefor. The Issuer, the Registrar, the Trustee and any agent of the Issuer, the Registrar or the Trustee may treat the person in whose name this Bond is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Bond be overdue, and neither the Issuer, the Registrar, the Trustee, any paying agent nor any such agent shall be affected by notice to the contrary. The Bonds are equally and ratably secured, to the extent provided in the Indenture, by the pledge thereunder of the "Revenues," which term is used herein as defined in the Indenture and which as therein defined means all moneys paid or payable to the Trustee for the account of the Issuer in accordance with the Loan Agreement and all receipts credited under the provisions of the Indenture against such payments; provided, however, that "Revenues" shall not include moneys held by the Trustee to pay the purchase price of Bonds subject to purchase pursuant to the Indenture. The Issuer has also pledged and assigned to the Trustee as security for the Bonds all other rights and interests of the Issuer under the Loan Agreement (other than its rights to indemnification and certain administrative expenses and certain other rights). The Owner of this Bond shall have no right to enforce the provisions of the Indenture, or to institute action to enforce the covenants therein, or to take any action with respect to any Event of Default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture. With certain exceptions as provided therein, the Indenture and the Loan Agreement may be modified or amended only with the consent of the Provider (unless a Provider Default as A-10 101 specified in the Indenture shall have occurred and be continuing) and the Owners of not less than 60% in aggregate principal amount of all Bonds then Outstanding under the Indenture. Reference is hereby made to the Indenture, the Loan Agreement, the Credit Facility and the Tax Certificate, copies of which are on file with the Trustee, for the provisions, among others, with respect to the nature and extent of the rights, duties and obligations of the Issuer, the Company, the Trustee, the Registrar, the Remarketing Agent and the Owners of the Bonds. The Owner of this Bond, by the acceptance hereof, is deemed to have agreed and consented to and to be bound by the terms and provisions of the indenture, the Loan Agreement and the Tax Certificate. The Indenture prescribes the manner in which it may be discharged, including (a) a provision that the Bonds shall be deemed to be paid if moneys sufficient to pay the principal of, premium, if any, and interest on the Bonds and all necessary and proper fees, compensation and expenses of the Trustee, the Registrar, the Provider and the Remarketing Agent, shall have been deposited with the Trustee, after which the Bonds shall no longer be secured by or entitled to the benefits of the Indenture, except for the purposes of registration and exchange of Bonds and of delivery of the Bonds to the Trustee for purchase, and (b) a provision that, if the Bonds mature or are called for redemption prior to the next date upon which the Bonds are subject to purchase pursuant to the Indenture, and if the Company waives its right to convert the interest rate borne by the Bonds, the Bonds shall be deemed to be paid if Government Obligations, as defined therein, maturing as to principal and interest in such amounts and at such times as to insure the availability of sufficient moneys to pay the principal of, premium, if any, and interest on the Bonds and all necessary and proper fees, compensation and expenses of the Trustee and the Registrar, shall have been deposited with the Trustee, after which the Bonds shall no longer be secured by or entitled to the benefits of the Indenture, except for the purposes of registration and exchange of Bonds and of such payment. No recourse shall be had for the payment of the principal of, premium, if any, or interest on any of the Bonds or for any claim based thereon or upon any obligation, covenant or agreement in the Indenture contained, against any past, present or future officer, elected official agent or employee of the Issuer, or any incorporator, officer, director or member of any successor corporation, as such, either directly or through the Issuer or any successor corporation, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such incorporator, officer, director or member is hereby expressly waived and released as a condition of and in consideration for the execution of the Indenture and the issuance of any of the Bonds.

For the purposes hereof, an Order containing the information referred to in clause (i)(A) of this subsection (a) is herein referred to as a "Hold Order", an Order containing the information referred to in clause (i)(B) or (ii) of this subsection (a) is herein referred to as a "Bid", and an Order containing the information referred to in clause (i)(C) of this subsection (a) is herein referred to as a "Sell Order." (b) (i) A Bid by an Existing Owner shall constitute an irrevocable offer to sell: (A) the principal amount of the PARS Rate Bonds specified in such Bid if the rate determined by the Auction Procedures on such Auction Date shall be less than the rate specified therein; or (B) such principal amount or a lesser principal amount of the PARS Rate Bonds to be determined as set forth in subsection (a)(v) of Section 1.05 hereof if the rate determined by the Auction Procedures on such Auction Date shall be equal to such specified rate; or (C) a lesser principal amount of the PARS Rate Bonds to be determined as set forth in subsection (b)(iv) of Section 1.05 hereof if such specified rate shall be higher than the Maximum PARS Rate and Sufficient Clearing Bids do not exist. (ii) A Sell Order by an Existing Owner shall constitute an irrevocable offer to sell: (A) the principal amount of the PARS Rate Bonds specified in such Sell Order; or (B) such principal amount or a lesser principal amount of the PARS Rate Bonds as set forth in subsection (b)(iv) of Section 1.05 hereof if Sufficient Clearing Bids do not exist.

B-2 107 (c) Anything herein to the contrary notwithstanding: (i) for purposes of any Auction, any Order which specifies the PARS Rate Bonds to be held, purchased or sold in a principal amount which is not $25,000 or an integral multiple thereof shall be rounded down to the nearest $25,000, and the Auction Agent shall conduct the Auction Procedures as if such Order had been submitted in such lower amount; (ii) for purposes of any Auction other than during a daily Auction Period, any portion of an Order of an Existing Owner which relates to a PARS Rate Bond which has been called for redemption on or prior to the Interest Payment Date next succeeding such Auction shall be invalid with respect to such portion and the Auction Agent shall conduct the Auction Procedures as if such portion of such Order had not been submitted; (iii) for purposes of any Auction other than during a daily Auction Period, no portion of a PARS Rate Bond which has been called for redemption on or prior to the Interest Payment Date next succeeding such Auction shall be included in the calculation of Available Bonds for such Auction; (iv) the Auction Procedures shall be suspended during the period commencing on the date of the Auction Agent's receipt of notice from the Trustee or the Issuer of the occurrence of an Event of Default resulting from a failure to pay principal, premium or interest on any PARS Rate Bond when due (provided however that for purposes of this provision only payment by the Provider of the Credit Facility shall be deemed to cure such Event of Default and no such suspension of the Auction Procedures shall occur) but shall resume two Business Days after the date on which the Auction Agent receives notice from the Trustee that such Event of Default has been waived or cured, with the next Auction to occur on the next regularly scheduled Auction Date occurring thereafter; and (v) while the PARS Rate Bonds are in a PARS daily Auction Period, all PARS will be Tranche I PARS. SECTION 1.03. SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT. (a) Each Broker-Dealer shall submit to the Auction Agent in writing or by such other method as shall be reasonably acceptable to the Auction Agent, prior to the Submission Deadline on each Auction Date, all Orders obtained by such Broker-Dealer and specifying with respect to each Order: (i) the name of the Bidder placing such Order; (ii) the aggregate principal amount of the PARS Rate Bonds that are the subject of such Order; (iii) to the extent that such Bidder is an Existing Owner: B-3 108 (A) the principal amount of the PARS Rate Bonds, if any, subject to any Hold Order placed by such Existing Owner; (B) the principal amount of the PARS Rate Bonds, if any, subject to any Bid placed by such Existing Owner and the rate specified in such Bid; and (C) the principal amount of the PARS Rate Bonds, if any, subject to any Sell Order placed by such Existing Owner; and (iv) to the extent such Bidder is a Potential Owner, the rate specified in such Bid. (b) If any rate specified in any Bid contains more than three figures to the right of the decimal point, the Auction Agent shall round such rate up to the next highest one thousandth of one percent (0.001%). (c) If an Order or Orders covering all of the PARS Rate Bonds held by an Existing Owner is not submitted to the Auction Agent prior to the Submission Deadline, the Auction Agent shall deem a Hold Order to have been submitted on behalf of such Existing Owner covering the principal amount of the PARS Rate Bonds held by such Existing Owner and not subject to Orders submitted to the Auction Agent; provided, however, that if there is a conversion from one Auction Period to another Auction Period and Orders have not been submitted to the Auction Agent prior to the Submission Deadline covering the aggregate principal amount of the PARS Rate Bonds held by such Existing Owner, the Auction Agent shall deem a Sell Order to have been submitted on behalf of such Existing Owner covering the principal amount of the PARS Rate Bonds held by such Existing Owner not subject to Orders submitted to the Auction Agent. (d) If one or more Orders covering in the aggregate more than the principal amount of the Outstanding PARS Rate Bonds held by any Existing Owner are submitted to the Auction Agent, such Orders shall be considered valid as follows: (i) all Hold Orders shall be considered Hold Orders, but only up to and including in the aggregate the principal amount of the PARS Rate Bonds held by such Existing Owner; (ii) (A) any Bid of an Existing Owner shall be considered valid as a Bid of an Existing Owner up to and including the excess of the principal amount of the PARS Rate Bonds held by such Existing Owner over the principal amount of the PARS Rate Bonds subject to Hold Orders referred to in paragraph (i) above; (B) subject to clause (A), all Bids of an Existing Owner with the same rate shall be aggregated and considered a single Bid of an Existing Owner up to and including the excess of the principal amount of the PARS Rate Bonds held by such Existing Owner over the principal amount of the PARS Rate Bonds held by such Existing Owner subject to Hold Orders referred to in paragraph (i) above, B-4 109 (C) subject to clause (A), if more than one Bid with different rates is submitted on behalf of such Existing Owner, such Bids shall be considered Bids of an Existing Owner in the ascending order of their respective rates up to the amount of the excess of the principal amount of the PARS Rate Bonds held by such Existing Owner over the principal amount of the PARS Rate Bonds held by such Existing Owner subject to Hold Orders referred to in paragraph (i) above, and (D) the principal amount, if any, of such PARS Rate Bonds subject to Bids not considered to be Bids of an Existing Owner under this paragraph (ii) shall be treated as the subject of a Bid by a Potential Owner; and (iii) all Sell Orders shall be considered Sell Orders, but only up to and including a principal amount of the PARS Rate Bonds equal to the excess of the principal amount of the PARS Rate Bonds held by such Existing Owner over the sum of the principal amount of the PARS Rate Bonds considered to be subject to Hold Orders pursuant to paragraph (i) above and the principal amount of the PARS Rate Bonds considered to be subject to Bids of such Existing Owner pursuant to paragraph (ii) above. (e) If more than one Bid is submitted on behalf of any Potential Owner, each Bid submitted with the same rate shall be aggregated and considered a single Bid and each Bid submitted with a different rate shall be considered a separate Bid with the rate and the principal amount of the PARS Rate Bonds specified therein. (f) Any Bid submitted by an Existing Owner or a Potential Owner specifying a rate lower than the Minimum PARS Rate shall be treated as a Bid specifying the Minimum PARS Rate. (g) Neither the Company, the Issuer, the Trustee nor the Auction Agent shall be responsible for the failure of any Broker-Dealer to submit an Order to the Auction Agent on behalf of any Existing Owner or Potential Owner. SECTION 1.04. DETERMINATION OF PARS RATE. (a) Not later than 9:30 a.m., New York, New York time, on each Auction Date, the Auction Agent shall advise the Broker-Dealers and the Trustee by telephone of the Minimum PARS Rate, the Maximum PARS Rate and the PARS Index. (b) Promptly after the Submission Deadline on each Auction Date, the Auction Agent shall assemble all Orders submitted or deemed submitted to it by the Broker-Dealers (each such Order as submitted or deemed submitted by a Broker-Dealer being hereinafter referred to as a "Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, and collectively as a "Submitted Order") and shall determine (i) the Available Bonds, (ii) whether there are Sufficient Clearing Bids, and (iii) the Auction Rates. B-5 110 (c) Promptly after the Auction Agent has made the determinations pursuant to subsection (b) above, the Auction Agent shall advise the Trustee by telephone (promptly confirmed in writing), telex or facsimile transmission of the Auction Rates and the aggregate principal amount of each Tranche for the next succeeding Auction Period. (d) In the event the Auction Agent shall fail to calculate, or for any reason fail to timely provide the Auction Rates for any Auction Period, the PARS Rate for such Auction Period shall be the applicable No Auction Rate provided, however, that if the Auction Procedures are suspended pursuant to Section 1.02(iv), the PARS Rates for the next succeeding Auction Period shall be the Maximum PARS Rate. (e) In the event of a failed conversion to a Daily Interest Rate Period, a Weekly Interest Rate Period, a Flexible Interest Rate Period or a Term Interest Rate Period or in the event of a failure to change the length of the current Auction Period due to the lack of Sufficient Clearing Bids at the Auction on the Auction Date for the first new Auction Period, the PARS Rate for the next Auction Period shall be the Maximum PARS Rate and the Auction Period shall be a seven-day Auction Period.

(d) If, as a result of the procedures described in subsection (a) above, any Potential Owner would be required to purchase less than $25,000 in principal amount of the PARS Rate Bonds on any Auction Date, the Auction Agent shall by lot, in such manner as it shall determine in its sole discretion, allocate the PARS Rate Bonds for purchase among Potential Owners so that the principal amount of PARS purchased on such Auction Date by any Potential Owner shall be an integral multiple of $25,000, even if such allocation results in one or more of such Potential Owners not purchasing the PARS Rate Bonds on such Auction Date. SECTION 1.06. NOTICE OF PARS RATE. (a) On each Auction Date, the Auction Agent shall notify by telephone each Broker-Dealer that participated in the Auction held on such Auction Date and submitted an Order on behalf of any Existing Owner or Potential Owner of: (i) the PARS Rate fixed for the succeeding Auction Period or, in the case of PARS Rate Bonds in a daily Auction Period, the PARS Rate on the PARS Rate Bonds fixed for the current Auction Period; (ii) whether Sufficient Clearing Bids existed for the determination of the Winning Bid Rate; B-8 113 (iii) if such Broker-Dealer submitted a Bid or a Sell Order on behalf of an Existing Owner, whether such Bid or Sell Order was accepted or rejected, in whole or in part, and the principal amount of the PARS Rate Bonds, if any, to be sold by such Existing Owner; (iv) if such Broker-Dealer submitted a Bid on behalf of a Potential Owner, whether such Bid was accepted or rejected, in whole or in part, and the principal amount of the PARS Rate Bonds, if any, to be purchased by such Potential Owner; (v) if the aggregate principal amount of the PARS Rate Bonds to be sold by all Existing Owners on whose behalf such Broker-Dealer submitted Bids or Sell Orders is different from the aggregate principal amount of the PARS Rate Bonds to be purchased by all Potential Owners on whose behalf such Broker-Dealer submitted a Bid, the name or names of one or more Broker-Dealers (and the Agent Member, if any, of each such other Broker-Dealer) and the principal amount of the PARS Rate Bonds to be (A) purchased from one or more Existing Owners on whose behalf such other Broker-Dealers submitted Bids or Sell Orders or (B) sold to one or more Potential Owners on whose behalf such Broker-Dealer submitted Bids; and (vi) the immediately succeeding Auction Date. (b) On each Auction Date, each Broker-Dealer that submitted an Order on behalf of any Existing Owner or Potential Owner shall: (i) advise each Existing Owner and Potential Owner on whose behalf such Broker-Dealer submitted a Bid or Sell Order whether such Bid or Sell Order was accepted or rejected, in whole or in part; (ii) instruct each Potential Owner on whose behalf such Broker-Dealer submitted a Bid that was accepted, in whole or in part, to instruct such Potential Owner's Agent Member to pay to such Broker-Dealer (or its Agent Member) through the Securities Depository the amount necessary to purchase the principal amount of the PARS Rate Bonds to be purchased pursuant to such Bid (including, with respect to the PARS Rate Bonds in a daily Auction Period, accrued interest if the purchase date is not an Interest Payment Date for such PARS Rate Bond) against receipt of such the PARS Rate Bonds; (iii) instruct each Existing Owner on whose behalf such Broker-Dealer submitted a Sell Order that was accepted or a Bid that was rejected, in whole or in part, to instruct such Existing Owner's Agent Member to deliver to such Broker-Dealer (or its Agent Member) through the Securities Depository the principal amount of the PARS Rate Bonds to be sold pursuant to such Bid or Sell Order against payment therefor; (iv) advise each Existing Owner on whose behalf such Broker-Dealer submitted an Order and each Potential Owner on whose behalf such Broker-Dealer submitted a Bid of the PARS Rate for the next succeeding Auction Period; B-9 114 (v) advise each Existing Owner on whose behalf such Broker-Dealer submitted an Order of the Auction Date of the next succeeding Auction or, in the case of PARS Rate Bonds in a daily Auction Period, the PARS Rate for the current Auction Period; and (vi) advise each Potential Owner on whose behalf such Broker-Dealer submitted a Bid that was accepted, in whole or in part, of the Auction Date of the next succeeding Auction. (c) On the basis of the information provided to it pursuant to paragraph (a) above, each Broker-Dealer that submitted a Bid or Sell Order shall allocate any funds received by it pursuant to subparagraph (b)(ii) above, and any PARS Rate Bonds received by it pursuant to (b)(iii) above, among the Potential Owners, if any, on whose behalf such Broker-Dealer submitted Bids, the Existing Owners, if any, on whose behalf such Broker-Dealer submitted Bids or Sell Orders, and any Broker-Dealer identified to it by the Auction Agent pursuant to subparagraph (a)(v) above. (d) On the Business Day after the Auction Date or, in the case of PARS Rate Bonds in a daily Auction Period, on such Auction Date, the Securities Depository shall execute the transactions described above, debiting and crediting the accounts of the respective Agent Members as necessary to effect the purchase and sale of PARS Rate Bonds as determined in the Auction. SECTION 1.07. PARS INDEX. (a) the PARS Index on any Auction Date with respect to the PARS Rate Bonds in any Auction Period other than a six-month Auction Period shall be the Seven-Day "AA" Composite Commercial Paper Rate on such date. The PARS Index respect to the PARS Rate Bonds in a six-month Auction Period shall be the Six-Month Treasury Bill Rate, as last published in The Bond Buyer. If either rate is unavailable, the PARS Index shall be a rate agreed to by all Broker-Dealers and consented to by the Issuer. "Seven-Day `AA' Composite Commercial Paper Rate" on any date of determination, means the interest equivalent of the seven-day rate on commercial paper placed on behalf of issuers whose corporate bonds are rated AA by S&P, or the equivalent of such rating by S&P, as made available on a discount basis or otherwise by the Federal Reserve Bank of New York for the Business Day immediately preceding such date of determination, or (B) if the Federal Reserve Bank of New York does not make available any such rate, then the arithmetic average of such rates, as quoted on a discount basis or otherwise, by Goldman, Sachs & Co., Lehman Commercial Paper Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated or, in lieu of any thereof, their respective affiliates or successors which are commercial paper dealers (the "Commercial Paper Dealers"), to the Auction Agent for the close of business on the Business Day immediately preceding such date of determination. For purposes of the definitions of Seven-Day "AA" Composite Commercial Paper Rate, the "interest equivalent" means the equivalent yield on a 360-day basis of a discount-basis security to an interest-bearing security. If any Commercial Paper Dealer does not quote a commercial paper rate required to determine the Seven-Day "AA" Composite Commercial Paper Rate, the B-10 115 Seven-Day "AA" Composite Commercial Paper Rate shall be determined on the basis of the quotation or quotations furnished by the remaining Commercial Paper Dealer or Commercial Paper Dealers and any substitute commercial paper dealer not included within the definition of Commercial Paper Dealer above, which may be CS First Boston Corporation or Morgan Stanley Dean Witter or their respective affiliates or successors which are commercial paper dealers (a "Substitute Commercial Paper Dealer") selected by the Trustee (who shall be under no liability for such selection) to provide such commercial paper rate or rates not being supplied by any Commercial Paper Dealer or Commercial Paper Dealers, as the case may be, or if the Trustee does not select any such substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers, by the remaining Commercial Paper Dealer or Commercial Paper Dealers. (b) If for any reason on any Auction Date the PARS Index shall not be determined as hereinabove provided in this Section, the PARS Index shall be the PARS Index for the Auction Period ending on such Auction Date. (c) The determination of the PARS Index as provided herein shall be conclusive and binding upon the Issuer, the Company, the Trustee, the Broker-Dealers, the Auction Agent and the Owners and Beneficial Owners of the PARS Rate Bonds. SECTION 1.08. MISCELLANEOUS PROVISIONS REGARDING AUCTIONS. (a) In this Exhibit B, each reference to the purchase, sale or holding of "PARS Rate Bonds" shall refer to beneficial interests in the PARS Rate Bonds, unless the context clearly requires otherwise. (b) During a PARS Rate Period, the provisions of Section 1.02 hereof and this Exhibit B may be amended pursuant to Section 12.02 of the Indenture by obtaining the consent of the Provider of the Credit Facility and the owners of all Outstanding PARS Rate Bonds bearing interest at the PARS Rates as follows. If on the first Auction Date occurring at least 20 days after the date on which the Trustee mailed notice of such proposed amendment to the Owners of the Outstanding PARS as required by Section 12.02, (i) Sufficient Clearing Bids have been received or all of the PARS are subject to Submitted Hold Orders, and (ii) there is delivered to the Issuer and the Trustee a Favorable Opinion of Bond Counsel with respect to such amendment, the proposed amendment shall be deemed to have been consented to by the owners of all Outstanding PARS. Notwithstanding the foregoing, for so long as Goldman, Sachs & Co. is a Broker-Dealer, there may not be a change in the definitions of Broker-Dealer Rate, Tranche I PARS or Tranche II PARS without the consent of Goldman, Sachs & Co. (c) During a PARS Rate Period, so long as the ownership of the PARS Rate Bonds is maintained in book-entry form by the Securities Depository, an Existing Owner or a beneficial owner may sell, transfer or otherwise dispose of a the PARS Rate Bond only pursuant to a Bid or Sell Order in accordance with the Auction Procedures or to or through a Broker-Dealer or to a Person that has delivered a signed copy of a Master Purchaser's Letter to the Auction Agent, provided that (i) in the case of all transfers other than pursuant to Auctions such Existing Owner or its Broker-Dealer or its Agent Member advises the Auction Agent of such transfer and (ii) a sale, transfer or other disposition of the PARS Rate Bonds from a customer of a Broker-Dealer B-11 116 who is listed on the records of that Broker-Dealer as the Owner of such PARS Rate Bonds to that Broker-Dealer or another customer of that Broker-Dealer shall not be deemed to be a sale, transfer or other disposition for purposes of this Section 1.08 if such Broker-Dealer remains the Existing Owner of the PARS Rate Bonds so sold, transferred or disposed of immediately after such sale, transfer or disposition. SECTION 1.09. CHANGES IN AUCTION PERIOD OR AUCTION DATE. (a) Changes in Auction Period. (i) During any PARS Rate Period, the Company, may, from time to time on any Interest Payment Date, change the length of the Auction Period with respect to the PARS Rate Bonds between daily, seven days, 28 days, 35 days and six months in order to accommodate economic and financial factors that may affect or be relevant to the length of the Auction Period and the interest rate borne by such PARS Rate Bonds. The Company shall initiate the change in the length of the Auction Period by giving written notice to the Issuer, the Trustee, the Auction Agent, the Broker-Dealers, the Provider of the Credit Facility and the Securities Depository that the Auction Period will change if the conditions described herein are satisfied and the proposed effective date of the change, at least 10 Business Days prior to the Auction Date for such Auction Period. (ii) Any such changed Auction Period shall be for a period of one day, seven days, 28 days, 35 days or six months and shall be for all of the PARS Rate Bonds in a PARS Rate Period. (iii) The change in the length of the Auction Period shall not be allowed unless Sufficient Clearing Bids existed at both the Auction before the date on which the notice of the proposed change was given as provided in this subsection (a) and the Auction immediately preceding the proposed change. (iv) The change in length of the Auction Period shall take effect only if Sufficient Clearing Bids exist at the Auction on the Auction Date for such first Auction Period. For purposes of the Auction for such first Auction Period only, each Existing Owner shall be deemed to have submitted Sell Orders with respect to all of its the PARS Rate Bonds except to the extent such Existing Owner submits an Order with respect to such Bonds. If the condition referred to in the first sentence of this paragraph (iv) is not met, the Auction Rate for the next Auction Period shall be the Maximum PARS Rate, and the Auction Period shall be a seven-day Auction Period. (v) On the conversion date for the PARS Rate Bonds selected for conversion from one Auction Period to another, any PARS Rate Bonds which are not the subject of a specific Hold Order or Bid will be deemed to be subject to a Sell Order. (b) Changes in Auction Date. During any PARS Rate Period, the Auction Agent, with the written consent of the Issuer, may specify an earlier Auction Date (but in no event more than five Business Days earlier) than the Auction Date that would otherwise be determined in B-12 117 accordance with the definition of "Auction Date" in order to conform with then current market practice with respect to similar securities or to accommodate economic and financial factors that may affect or be relevant to the day of the week constituting an Auction Date and the interest rate borne on the PARS Rate Bonds. The Issuer shall not consent to such change in the Auction Date unless it shall have received from the Auction Agent not less than three days nor more than 20 days prior to the effective date of such change a written request for consent together with a certificate demonstrating the need for change in reliance on such factors. The Auction Agent shall provide notice of its determination to specify an earlier Auction Date for an Auction Period by means of a written notice delivered at least 45 days prior to the proposed changed Auction Date to the Trustee, the Company, the Issuer, the Broker-Dealers and the Securities Depository. (c) Changes Conditioned on Ratings. Notwithstanding anything herein to the contrary, prior to any change in the duration of an Auction Period, the Trustee shall receive written evidence from Moody's, if the Bonds are then rated by Moody's, and from S&P, if the Bonds are then rated by S&P, in each case to the effect that such rating agency has reviewed the proposed Change of Credit Facility and that such Change of Credit Facility will not, by itself, result in a reduction, suspension or withdrawal of its rating or ratings of the Bonds. SECTION 1.10. AUCTION AGENT. (a) The initial Auction Agent shall be IBJ Whitehall Bank & Trust Company, New York, New York, or any successor appointed by the Trustee, at the written direction of the Company, to perform the functions specified herein. The Auction Agent shall designate its Principal Office and signify its acceptance of the duties and obligations imposed upon it hereunder by a written instrument, delivered to the Issuer, the Trustee, the Company and each Broker-Dealer which will set forth such procedural and other matters relating to the implementation of the Auction Procedures as shall be satisfactory to the Issuer and the Trustee. (b) Subject to any applicable governmental restrictions, the Auction Agent may be or become the owner of or trade in the PARS Rate Bonds with the same rights as if such entity were not the Auction Agent. SECTION 1.11. QUALIFICATIONS OF AUCTION AGENT: RESIGNATION; REMOVAL. The Auction Agent shall be (a) a bank or trust company organized under the laws of the United States or any state or territory thereof having a combined capital stock, surplus and undivided profits of at least $30,000,000, or (b) a member of NASD having a capitalization of at least $30,000,000 and, in either case, authorized by law to perform all of the duties imposed upon it by this Indenture and a member of or a participant in, the Securities Depository.

The Auction Agent may be removed at any time by the Company by written notice, delivered to the Auction Agent, the Company, the Trustee and the Provider. Upon any such resignation or removal, the Trustee shall, at the direction of the Company, appoint a successor Auction Agent meeting the requirements of this Section. In the event of the resignation or removal of the Auction Agent, the Auction Agent shall pay over, assign and deliver any moneys and the PARS Rate Bonds held by it in such capacity to its successor. The Auction Agent shall continue to perform its duties B-13 118 hereunder until its successor has been appointed by the Issuer. In the event that the Auction Agent has not been compensated for its services, the Auction Agent may resign by giving thirty (30) days notice to the Issuer, the Company, the Trustee and the Provider even if a successor Auction Agent has not been appointed.
