In case of redemption of 2016 PC Bond in whole for the purpose of prepayment under the Loan Agreement pursuant to subsections (a), (b), (c), (d), (f), (g), (h) or (i) above, the amounts payable upon redemption of 2016 PC Bond shall be a sum sufficient, together with other funds deposited with the City Trustee and available for such purpose, to pay the principal of (and premium, in the case of redemption pursuant to (f) above), and interest on the 2016 PC Bond then outstanding and to pay all reasonable and necessary fees and expenses of the City Trustee accrued and to accrue through final payment of the 2016 PC Bond.

(e) In part, at the option of the Company, to the extent of net proceeds received from any condemnation award, taking or sale as stated herein, if title to, or the temporary use of any portion of the Facilities shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency; provided the Company shall furnish to the City and the City Trustee a certificate of an Independent Engineer (as defined in the Loan Agreement) selected by the Company stating (i) that the property forming the part of the Facilities that was taken by such condemnation, taking or sale is not essential to the character or significance of the Facilities, or (ii) that the Facilities have been restored to a condition substantially equivalent to their condition prior to the taking by such condemnation, taking or sale proceedings, or (iii) that improvements have been acquired which are suitable for the operation of the Facilities. (f) In the event all or substantially all of the mortgaged and pledged property under the Mortgage, or all or substantially all such property used in the business of generating, manufacturing, transporting, transmitting, distributing or supplying electricity, should be taken by exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency, the Company shall be obligated to redeem the 2017 PC Bond outstanding as promptly as possible in accordance with paragraph B of Section 69 of the Original Mortgage. (g) In the event that the Company is notified by the City Trustee that (i) an event of default under the City Indenture has occurred and is continuing, and (ii) the City Trustee has declared the principal of all the Series 1993B Bonds then outstanding immediately due and payable pursuant to the City Indenture, the Company shall call for redemption, on a redemption date selected by it not later than thirty (30) days following the date on which such notice is mailed, the 2017 PC Bond outstanding, and shall on such redemption date redeem the same; provided, however, that such requirement of redemption shall be deemed waived, if prior to the date fixed for such redemption of the 2017 PC Bond (x) such event of default is waived or cured as set forth in the City Indenture, or (y) there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2017 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; and in case of any subsequent occurrence or continuance of the events described in (i) and (ii) of this Section 2(g), the Company shall have the same obligation (subject to the same proviso) to redeem the 2017 PC Bond. (h) In the event the City Trustee notifies the Company and the City that the interest payable on the Series 1993B Bonds held by persons other than a "substantial user" or a "related person" as those terms are used in Section 147(a)(2) of the Internal Revenue code of 1986, as amended, has been determined by a court of competent jurisdiction or a formal ruling of the Internal Revenue Service to be subject to federal income taxation by reason of a breach by the Company of any covenant, agreement or representation in the Loan Agreement, the Company shall call the 2017 PC Bond then outstanding to be redeemed on the next succeeding interest payment date within one hundred eighty (180) days after the date of such notice; provided, however, that such requirement of redemption, whether in whole or in part shall be deemed waived if, prior to the date fixed for redemption of the 2017 PC Bond pursuant to this Section 2(h), there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2017 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; but when any such completed default shall have been cured and made good, if interest on the Series 1993B Bonds shall still be taxable as described above, the Company shall have the same obligation (subject to the same proviso) to redeem the 2017 PC Bond on the next succeeding interest payment date within one hundred eighty (180) days after the curing and making good of such completed default; provided further, that the Company may call for redemption such portion of the 2017 PC Bond, which in the written opinion of an attorney or firm of attorneys of nationally recognized standing on the subject of municipal bonds, would allow the City Trustee to redeem the Series 1993B Bonds in part, which redemption would have the result that the interest payable on the Series 1993B Bonds remaining outstanding after such redemption in part would not be subject to federal income taxation in the hands of persons other than a "substantial user" or a "related person" as those terms are used in Section 147(a)(2) of the Internal Revenue Code of 1986, as amended. In case of redemption of 2017 PC Bond in whole for the purpose of prepayment under the Loan Agreement pursuant to subsections (a), (b), (c), (d), (f), (g), or (h) above, the amounts payable upon redemption of 2017 PC Bond shall be a sum sufficient, together with other funds deposited with the City Trustee and available for such purpose, to pay the principal of and interest on the 2017 PC Bond then outstanding and to pay all reasonable and necessary fees and expenses of the City Trustee accrued and to accrue through final payment of the 2017 PC Bond. In case of redemption in part pursuant to (e) or (h) above, the amount payable by the Company under this Thirty-Seventh Supplemental Indenture, the Loan Agreement and the 2017 PC Bond shall be a sum sufficient, together with other funds deposited with the Trustee and available for such purpose, to pay the principal of and interest on the 2017 PC Bond so to be redeemed, which sum together with other funds deposited with the City Trustee and available for such purpose shall be sufficient to pay the principal of, premium, if any, and interest on the Series 1993B Bonds and to pay all reasonable and necessary fees and expenses of the City Trustee accrued and to accrue through such partial prepayment. The 2017 PC Bond and the Series 1993B Bonds shall be redeemable at any time within one hundred eighty (180) days following the event or events described as giving rise to an option of the Company to redeem them in subsections (a), (b), (c), (d) or (e) above. To exercise any of the options granted to redeem the 2017 PC Bond in whole or in part or to comply with any obligations to redeem the 2017 PC Bond in whole or in part imposed in this Section 2, the Company shall give written notice of the date of redemption to the City Trustee, which date shall be not less than thirty (30) days nor more than ninety (90) days from the date the notice is mailed. No further notice, by publication or otherwise, shall be required for redemption of the 2017 PC Bond, and the requirements of Section 59 of the Mortgage for notice by newspaper publication shall not apply to the 2017 PC Bond. At the option of the holder, the 2017 PC Bond, upon surrender thereof at the office or agency of the Company in Chicago, Illinois, together with a written instrument of transfer in form approved by the Company duly executed by the holder or by his duly authorized attorney, shall be exchangeable for a like aggregate principal amount of fully registered bonds of the same series of other authorized denominations.

The Company shall not be required to make transfers or exchanges of any of the 2004 Bonds for a period of ten (10) days next preceding any interest payment date of said bonds. No charge shall be made upon any transfer or exchange of any of the 2004 Bonds other than for any tax or taxes or other governmental charge required to be paid by the Company.

Upon the notice and in the manner and with the effect provided in this Section 2, the 2021 PC Bond shall be redeemable prior to the maturity thereof under any one or more of the following circumstances: (a) In whole, at the option of the Company, if the Facilities or the Plant shall have been damaged or destroyed to such extent that (i) it cannot be reasonably expected, in the opinion of the Company, to be restored within a period of six (6) months to the condition thereof immediately preceding such damage or destruction, or (ii) to such extent that the Company, in its reasonable opinion, is thereby prevented from carrying on its normal operations for a period of six (6) months or more, or (iii) to such extent that the restoration thereof would not be, taking into consideration the net proceeds of any insurance payable as a result of such damage or destruction, economic in the reasonable opinion of the Company. (b) In whole, at the option of the Company, if title to, or the temporary use of, all or substantially all of the Facilities or the Plant, shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser for the same, or should such property be sold to any governmental body or agency so that the result of such taking or takings is that (i) the Company, in its reasonable opinion, is thereby prevented from carrying on its normal operations of either the Facilities or the Plant for a period of six (6) months or more, (ii) the restoration required as a result of the taking cannot be reasonably expected, in the opinion of the Company, to be completed in a period of six (6) months, or (iii) the restoration thereof, taking into consideration the net proceeds from such eminent domain award, would not be economic in the reasonable opinion of the Company. (c) In whole, at the option of the Company, if, as a result of any changes in the Constitution or law of the State of Indiana or the Constitution or law of the United States of America or of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or administrative body (whether state or federal) the Loan Agreement or the Note shall, in the reasonable opinion of counsel for the Company, have become void or unenforceable or impossible of performance in accordance with the intent and purpose of the parties as expressed in the Loan Agreement; or unreasonable burdens or excessive liabilities shall, in the reasonable opinion of the Company, have been imposed upon the City or the Company, with respect to the Facilities or operation thereof, including without limitation federal, state or other ad valorem, property, income or other taxes not being imposed on the date of the Loan Agreement other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Facilities. (d) In whole, at the option of the Company, if changes in the economic availability of raw materials, operating supplies or facilities necessary for the operation of the Facilities or the Plant shall have occurred or technological or other changes shall have occurred which render the Facilities uneconomic for use in the reasonable opinion of the Company. (e) In part, at the option of the Company, to the extent of net proceeds, received from any condemnation award, taking or sale as stated herein, if title to, or the temporary use of any portion of the Facilities shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency; provided the Company shall furnish to the City and the City Trustee a certificate of an Independent Engineer (as defined in the Loan Agreement) selected by the Company stating (i) that the property forming the part of the Facilities that was taken by such condemnation, taking or sale is not essential to the character or significance of the Facilities, or (ii) that the Facilities have been restored to a condition substantially equivalent to their condition prior to the taking by such condemnation, taking or sale proceedings, or (iii) that improvements have been acquired which are suitable for the operation of the Facilities as a qualified exempt facility. (f) In whole or in part, at the option of the Company at any time on or after August 1, 2011, at a price equal to the principal amount of the 2021 PC Bond so to be redeemed and accrued interest to the date of redemption, together with a premium equal to a percentage of the principal amount thereof set forth under the heading "Redemption Premium" in the form of the 2021 PC Bond hereinafter recited, so long as the Company is not in default under the Loan Agreement or the 2021 PC Bond. (g) In the event all or substantially all of the mortgaged and pledged property under the Mortgage, or all or substantially all such property used in the business of generating, manufacturing, transporting, transmitting, distributing or supplying electricity, should be taken by exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency, the Company shall be obligated to redeem the 2021 PC Bond outstanding as promptly as possible in accordance with paragraph B of Section 69 of the Original Mortgage. (h) In the event that the Company is notified by the City Trustee that (i) an event of default under the City Indenture has occurred and is continuing, and (ii) the City Trustee has declared the principal of all the Series 1991 Bonds then outstanding immediately due and payable pursuant to the City Indenture, the Company shall call for redemption, on a redemption date selected by it not later than thirty (30) days following the date on which such notice is mailed, the 2021 PC Bond outstanding, and shall on such redemption date redeem the same; provided, however, that such requirement of redemption shall be deemed waived, if prior to the date fixed for such redemption of the 2021 PC Bond (x) such event of default is waived or cured as set forth in the City Indenture, or (y) there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2021 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; and in case of any subsequent occurrence or continuance of the events described in (i) and (ii) of this Section 2(h), the Company shall have the same obligation (subject to the same proviso) to redeem the 2021 PC Bond. (i) In the event the City Trustee notifies the Company and the City that the interest payable on the Series 1991 Bonds held by persons other than a "substantial user" or a "related person" as those terms are used in Section 147(a)(2) of the Internal Revenue Code of 1986, as amended, has been determined by a court of competent jurisdiction or a formal ruling of the Internal Revenue Service to be subject to federal income taxation by reason of a breach by the Company of any covenant, agreement or representation in the Loan Agreement, the Company shall call the 2021 PC Bond then outstanding to be redeemed within ninety (90) days after the date of such notice; provided, however, that such requirement of redemption, whether in whole or in part shall be deemed waived if, prior to the date fixed for redemption of the 2021 PC Bond pursuant to this Section 2(i), there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2021 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; but when any such completed default shall have been cured and made good, if interest on the Series 1991 Bonds shall still be taxable as described above, the Company shall have the same obligation (subject to the same proviso) to redeem the 2021 PC Bond within ninety (90) days after the curing and making good of such completed default; provided further, that the Company may call for redemption such portion of the 2021 PC Bond, which in the written opinion of an attorney or firm of attorneys of nationally recognized standing on the subject of municipal bonds, would allow the City Trustee to redeem the Series 1991 Bonds in part, which redemption would have the result that the interest payable on the Series 1991 Bonds remaining outstanding after such redemption in part would not be subject to federal income taxation in the hands of persons other than a "substantial user" or a "related person" as those terms are used in Section 147(a)(2) of the Internal Revenue Code of 1986, as amended. In case of redemption of the 2021 PC Bond in whole for the purpose of prepayment under the Loan Agreement pursuant to subsections (a), (b), (c), (d), (f), (g), (h) or (i) above, the amounts payable upon redemption of the 2021 PC Bond shall be a sum sufficient, together with other funds deposited with the City Trustee and available for such purpose, to pay the principal of (and premium, in the case of redemption pursuant to (f) above), and interest on the 2021 PC Bond then outstanding and to pay all reasonable and necessary fees and expenses of the City Trustee accrued and to accrue through final payment of the 2021 PC Bond.

The 2021 PC Bond and the Series 1991 Bonds shall be redeemable at any time within one hundred eighty (180) days following the event or events described as giving rise to an option of the Company to redeem them in subsections (a), (b), (c), (d) or (e) above.

(e) In part, at the option of the Company, to the extent of net proceeds, received from any condemnation award, taking or sale as stated herein, if title to, or the temporary use of any portion of the Facilities shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency; provided the Company shall furnish to the City and the City Trustee a certificate of an Independent Engineer (as defined in the Loan Agreement) selected by the Company stating (i) that the property forming the part of the Facilities that was taken by such condemnation, taking or sale is not essential to the character or significance of the Facilities, or (ii) that the Facilities have been restored to a condition substantially equivalent to their condition prior to the taking by such condemnation, taking or sale proceedings, or (iii) that improvements have been acquired which are suitable for the operation of the Facilities as a qualified exempt facility.

With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage and/or any instruments supplemental thereto may be modified or altered by affirmative vote of the holders of at least sixty-six and two-thirds percent (66-2/3%) in principal amount of the bonds affected by such modification or alteration then outstanding under the Mortgage (excluding bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); provided that no such modification or alteration shall permit the extension of the maturity of the principal of this 2024 PC Bond or the reduction in the rate of interest hereon or any other modification in the terms of payment of such principal or interest without the consent of the holder hereof. The principal hereof may be declared or may become due and payable prior to the stated date of maturity hereof, on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. No reference herein to the Mortgage, and no provision of this 2024 PC Bond or of the Mortgage, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay, subject to the provisions of the Forty-Fourth Supplemental Indenture, the principal of, and premium, if any, and interest on this 2024 PC Bond at the place, at the respective times and at the rate and the manner herein prescribed. This 2024 PC Bond is issuable only in full registered form without coupons in denominations of Five Thousand Dollars ($5,000) and any larger denomination which is a whole multiple of Five Thousand Dollars ($5,000). This 2024 PC Bond will be nontransferable except to the City Trustee and successors thereto, if any, and to the Company. To the extent that it is transferable, it is transferable by the registered holder thereof, in person or by attorney duly authorized in writing, on the books of the Company at the office or agency of the Company in the City of Chicago, Illinois, upon surrender thereof for cancellation at said office and upon presentation of a written instrument of transfer duly executed. Thereupon, the Company shall issue in the name of the transferee, and the Trustee shall authenticate and deliver, a new registered 2024 PC Bond, in an authorized denomination, of equal principal amount. Any such transfer shall be subject to the terms and conditions specified in the Mortgage and in the Forty-Fourth Supplemental Indenture. Upon redemption of this 2024 PC Bond in part and surrender thereof at the office or agency of the Company in Chicago, Illinois, for exchange, the Trustee shall authenticate and deliver a new registered 2024 PC Bond in an authorized denomination and principal amount equal to the reduced principal amount due on that series after such partial redemption.

(b) Except as otherwise provided in this Section 5, the principal amount of any Series 1994A Bond acquired by the Company and delivered to the City Trustee, or acquired by the City Trustee and cancelled, shall be credited against the obligation of the Company to pay the principal of the 2024 PC Bond. As the principal of, premium, if any, and interest on the 2024 PC Bond is paid or deemed paid in full, and upon its receipt by the Company, such bond shall be delivered to the Trustee for cancellation. The Company shall promptly inform the Trustee of all payments made and credits availed of with respect to its obligations on the 2024 PC Bond. The Trustee shall not be required to recognize any payment made or credit availed of with respect to any 2024 PC Bond unless it has received (a) the bond for cancellation by it, or (b) a certificate signed by a duly authorized officer of the City Trustee specifying the amount of such payment or credit and the principal amount of the 2024 PC Bond with respect to which the payment or credit was applied. In the absence of receipt by the Trustee of any 2024 PC Bond, any such certificate shall be controlling and conclusive. SECTION 6.

In case of redemption of the 2029 PC Bond in whole for the purpose of prepayment under the Loan Agreement pursuant to subsections (a), (b), (c), (d), (f), (g), (h) or (i) above, the amounts payable upon redemption of the 2029 PC Bond shall be a sum sufficient, together with other funds deposited with the City Trustee and available for such purpose, to pay the principal of (and premium, in the case of redemption pursuant to (f) above), and interest on the 2029 PC Bond then outstanding and to pay all reasonable and necessary fees and expenses of the City Trustee accrued and to accrue through final payment of the 2029 PC Bond.

The 2030 PC Bond shall be dated as of the date of authentication thereof, except as otherwise provided in Section 10 of the Original Mortgage. The 2030 PC Bond will be issued to evidence and secure a loan to the Company by the Authority pursuant to the Loan Agreement of certain funds previously acquired by the Authority through the issuance of Indiana Development Finance Authority Exempt Facilities Revenue Refunding Bonds, Series 1999 (Indianapolis Power & Light Company Project) (the "Series 1999 Bonds"), authenticated and delivered under and pursuant to an Indenture of Trust dated as of September 1, 1999, as amended and supplemented by the First Supplement and Amendment to Indenture of Trust dated as of August 1, 2001 (together hereinafter called the "Authority Indenture"), by and between National City Bank of Indiana, as Trustee (the "Authority Trustee") and the Authority. Pursuant to the Authority's pledge and assignment of the Loan Agreement, as set forth in the Authority Indenture, the 2030 PC Bond shall be issued to the Authority and assigned to the Authority Trustee. All of the proceeds of the Series 1999 Bonds were used for the refunding of the aggregate principal amount of Twenty Three Million Five Hundred Thousand ($23,500,000) of the Indiana Employment Development Commission (the "Commission") Exempt Facilities Revenue Bonds, Series 1989 (Indianapolis Power & Light Company Project) issued by the Commission pursuant to applicable loan agreements. Upon the notice and in the manner and with the effect provided in this Section 2, the 2030 PC Bond shall be redeemable prior to the maturity thereof under any one or more of the following circumstances: (a) In part, at the option of the Company, if any Project component or the facilities serviced thereby shall have been damaged or destroyed to such extent that (i) it cannot be reasonably expected, in the opinion of the Company, to be restored within a period of six (6) months to the condition thereof immediately preceding such damage or destruction, or (ii) to such extent that the Company, in its reasonable opinion, is thereby prevented from carrying on its normal operations for a period of six (6) months or more, or (iii) to such extent that the restoration thereof would not be, taking into consideration the net proceeds of any insurance payable as a result of such damage or destruction, economic in the reasonable opinion of the Company. (b) In part, at the option of the Company, if title to, or the temporary use of, all or substantially all of any Project component or the facilities serviced thereby, shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency so that the result of such taking or takings is that (i) the Company, in its reasonable opinion, is thereby prevented from carrying on its normal operations for a period of six (6) months or more, (ii) the restoration required as a result of the taking cannot be reasonably expected, in the opinion of the Company, to be completed in a period of six (6) months, or (iii) the restoration thereof, taking into consideration the net proceeds from such eminent domain award, would not be economic in the reasonable opinion of the Company. (c) In whole, at the option of the Company, if, as a result of any changes in the Constitution or law of the State of Indiana or the Constitution or law of the United States of America or of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or administrative body (whether state or federal) the Loan Agreement, the Note or the 2030 PC Bond shall, in the reasonable opinion of counsel for the Company, have become void or unenforceable or impossible of performance in accordance with the intent and purpose of the parties as expressed in the Loan Agreement; or unreasonable burdens or excessive liabilities shall, in the reasonable opinion of the Company, have been imposed upon the Authority or the Company, with respect to the Project or operation thereof, including without limitation federal, state or other ad valorem, property, income or other taxes not being imposed on the date of the Loan Agreement other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Project. (d) In part, at the option of the Company, if changes in the economic availability of raw materials, operating supplies or facilities necessary for the operation of any Project component or facilities serviced thereby shall have occurred or technological or other changes shall have occurred which render the facilities uneconomic for use in the reasonable opinion of the Company. (e) In part, at the option of the Company, to the extent of net proceeds, received from any condemnation award, taking or sale as stated herein, if title to, or the temporary use of any portion of the Project shall have been taken under the exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency; provided the Company shall furnish to the Authority and the Authority Trustee a certificate of an Independent Engineer (as defined in the Loan Agreement) selected by the Company stating (i) that the property forming the part of the Project that was taken by such condemnation, taking or sale is not essential to the character or significance of the Project, or (ii) that the Project have been restored to a condition substantially equivalent to their condition prior to the taking by such condemnation, taking or sale proceedings, or (iii) that improvements have been acquired which are suitable for the operation of the Project as qualified exempt facilities. (f) In whole or in part, at the option of the Company at any time on or after August 1, 2011, at a price equal to the principal amount of the 2030 PC Bond so to be redeemed and accrued interest to the date of redemption, together with a premium equal to a percentage of the principal amount thereof set forth under the heading "Redemption Premium" in the form of the 2030 PC Bond hereinafter recited, so long as the Company is not in default under the Loan Agreement or the 2030 PC Bond. (g) In the event all or substantially all of the mortgaged and pledged property under the Mortgage, or all or substantially all such property used in the business of generating, manufacturing, transporting, transmitting, distributing or supplying electricity, should be taken by exercise of the power of eminent domain, or should any governmental body or agency exercise any right which it may have to purchase or designate a purchaser of the same, or should such property be sold to any governmental body or agency, the Company shall be obligated to redeem the 2030 PC Bond outstanding as promptly as possible in accordance with paragraph B of Section 69 of the Original Mortgage. (h) In the event that the Company is notified by the Authority Trustee that (i) an event of default under the Authority Indenture has occurred and is continuing, and (ii) the Authority Trustee has declared the principal of all the Series 1999 Bonds then outstanding immediately due and payable pursuant to the Authority Indenture, the Company shall call for redemption, on a redemption date selected by it not later than thirty (30) days following the date on which such notice is mailed, the 2030 PC Bond outstanding, and shall on such redemption date redeem the same; provided, however, that such requirement of redemption shall be deemed waived, if prior to the date fixed for such redemption of the 2030 PC Bond (x) such event of default is waived or cured as set forth in the Authority Indenture, or (y) there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2030 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; and in case of any subsequent occurrence or continuance of the events described in (i) and (ii) of this Section 2(h), the Company shall have the same obligation (subject to the same proviso) to redeem the 2030 PC Bond. (i) The Company shall call the 2030 PC Bond then outstanding to be redeemed within one hundred eighty (180) days after the date of the Company receives written notice from a bondholder, a beneficial owner or former bondholder or former beneficial owner, the Authority Trustee or the tender agent of a final determination by the Internal Revenue Service or a court of competent jurisdiction that, as a result of a failure by the Company to perform any of its agreements in the Agreement or the inaccuracy of any of its representations in the Agreement, the interest paid or to be paid on any Series 1999 Bond (except to a "substantial user" of the Project or a "related person" as those terms are used in Section 147(a) of the Internal Revenue Code of 1986, as amended, (the "Code")) is or was includable in the gross income of the Series 1999 Bond's owner for federal income tax purposes (a "Determination of Taxability"). No such determination will be considered final unless the bondholder, beneficial owner, former bondholder, or former beneficial owner involved in the determination give the Company, the Authority Trustee and the tender agent prompt written notice of the commencement of the proceedings resulting in the determination and offers the Company, subject to the Company's agreeing to pay all reasonable expenses of the proceeding and to indemnify the holder against all liabilities that might result in connection with the Bonds, the opportunity to control the defense of the proceeding. Fewer than all the 2030 PC Bonds may be redeemed if redemption of fewer than all would result in the interest payable on the Series 1999 Bonds remaining outstanding being not includable in the gross income for federal income tax purposes of any holder other than a "substantial user" or "related person." If fewer than all Series 1999 Bonds are redeemed, the Registrar will select the bonds to be redeemed by lot as provided in the Authority Indenture or by such other method acceptable to the Registrar as may be specified in an Opinion of Tax Counsel. Provided, however, that such requirement of redemption, whether in whole or in part shall be deemed waived if, prior to the date fixed for redemption of the 2030 PC Bond pursuant to this Section 2(i), there shall have occurred any completed default (as defined in the Mortgage) which affects any bond of any series outstanding under the Mortgage and which completed default has not been cured and made good prior to such redemption date, it being the intent of this proviso that, in lieu of such right to redemption, the holder of the 2030 PC Bond shall be entitled only to such rights as are available to the holders of bonds of any other series outstanding under the Mortgage in the event of such completed default; but when any such completed default shall have been cured and made good, if interest on the Series 1999 Bonds shall still be taxable as described above, the Company shall have the same obligation (subject to the same proviso) to redeem the 2030 PC Bond within one hundred eighty (180) days after the curing and making good of such completed default. IF THE LIEN OF THE INDENTURE IS DISCHARGED PRIOR TO THE OCCURRENCE OF A FINAL DETERMINATION OF TAXABILITY, THE BONDS WILL NOT BE REDEMED AS DESCRIBED IN THIS PARAGRAPH. (j) In part, if any governmental body or agency order the Company to divest itself or as a result of any legislative or administrative action (whether state or federal) or by final decree, judgment or the order of any court or administrative body (whether state or federal) the Company shall be required to divest itself of all or substantially all of any Project component or the facilities services thereby. In case of redemption of the 2030 PC Bond in whole for the purpose of prepayment under the Loan Agreement pursuant to subsections (a), (b), (c), (d), (f), (g), (h), (i) or (j) above, the amounts payable upon redemption of the 2030 PC Bond shall be a sum sufficient, together with other funds deposited with the Authority Trustee and available for such purpose, to pay the principal of (and premium, in the case of redemption pursuant to (f) above), and interest on the 2030 PC Bond then outstanding and to pay all reasonable and necessary fees and expenses of the Authority Trustee accrued and to accrue through final payment of the 2030 PC Bond. In case of redemption in part pursuant to (a), (b), (d), (e), (f), (i) or (j) above, the amount payable by the Company under this Forty-Sixth Supplemental Indenture, the Loan Agreement and the 2030 PC Bond shall be a sum sufficient, together with other funds deposited with the Trustee and available for such purpose, to pay the principal of (and premium in the case of prepayment pursuant to (f) above) and interest on the 2030 PC Bond so to be redeemed, which sum together with other funds deposited with the Authority Trustee and available for such purpose shall be sufficient to pay the principal of, premium, if any, and interest on the Series 1999 Bonds and to pay all reasonable and necessary fees and expenses of the Authority Trustee accrued and to accrue through such partial prepayment. The principal amount of the 2030 PC Bond subject to redemption pursuant to (a), (b), (d) and (j) above will be an amount equal to the amount of proceeds of the 2030 PC Bond allocated to the Project component affected by the related event, rounded up to the nearest $5,000 increment. The 2030 PC Bond and the Series 1999 Bonds shall be redeemable at any time within one hundred eighty (180) days following the event or events described as giving rise to an option of the Company to redeem them in subsections (a), (b), (c), (d), (e) or (f) above. To exercise any of the options granted to redeem the 2030 PC Bond in whole or in part or to comply with any obligations to redeem the 2030 PC Bond in whole or in part imposed in this Section 2, the Company shall give written notice of the date of redemption to the Authority Trustee, which date shall be not less than thirty (30) days from the date the notice is mailed. No further notice, by publication or otherwise, shall be required for redemption of the 2030 PC Bond, and the requirements of Section 59 of the Mortgage for notice by newspaper publication shall not apply to the 2030 PC Bond. At the option of the holder, the 2030 PC Bond, upon surrender thereof at the office or agency of the Company in Chicago, Illinois, together with a written instrument of transfer in form approved by the Company duly executed by the holder or by his duly authorized attorney, shall be exchangeable for a like aggregate principal amount of fully registered bonds of the same series of other authorized denominations. The 2030 PC Bond will be nontransferable except to the Authority Trustee and successors thereto, if any, and to the Company. To the extent that it is transferable, it is transferable by the registered holder thereof, in person or by attorney duly authorized in writing, on the books of the Company at the office or agency of the Company in the City of Chicago, Illinois, upon surrender thereof for cancellation at said office and upon presentation of a written instrument of transfer duly executed.
