The Notes

SECTION 2.01. Form, Dating and Denominations; Legends. (a) The Notes and the Trustee’s certificate of authentication related thereto will be substantially in the form attached as Exhibit A. The terms and provisions contained in the form of Note annexed as Exhibit A constitute, and are hereby expressly made, a part of the Indenture. The Notes may have notations, legends or endorsements required by law, rules of or agreements with national securities exchanges to which the Company is subject. Each Note will be dated the date of its authentication. The Notes will be issuable in minimum denominations of $2,000 in principal amount and integral multiples of $1,000 in excess thereof.

(b) (i) Except as otherwise provided in paragraph (c), Section 2.10(b)(iii) or (c), or Section 2.09(b)(iv), each Initial Note or Additional Note (other than a Permanent Offshore Note) will bear the Restricted Legend.

(d) By its acceptance of any Note bearing the Restricted Legend (or any beneficial interest in such a Note), each Holder thereof and each owner of a beneficial interest therein acknowledges the restrictions on transfer of such Note (and any such beneficial interest) set forth in this Indenture and in the Restricted Legend and agrees that it will transfer such Note (and any such beneficial interest) only in accordance with the Indenture and such legend.

SECTION 2.02. Execution and Authentication; Additional Notes. (a) An Officer shall execute the Notes for the Company by facsimile or manual signature in the name and on behalf of the Company. If an Officer whose signature is on a Note no longer holds that office at the time the Note is authenticated, the Note will still be valid.

(b) A Note will not be valid until the Trustee manually signs the certificate of authentication on the Note, with the signature conclusive evidence that the Note has been authenticated under the Indenture.

(c) At any time and from time to time after the execution and delivery of the Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication. The Trustee will authenticate and deliver

(i) Notes for original issue in the aggregate principal amount not to exceed $405,000,000, and

(ii) Additional Notes from time to time for original issue in aggregate principal amounts specified by the Company

after the following conditions have been met:

(1) Receipt by the Trustee of an Officers’ Certificate specifying

(A) the amount of Notes to be authenticated and the date on which such Notes are to be authenticated,

(B) whether such Notes are to be Initial Notes or Additional Notes,

(C) in the case of Additional Notes, that the issuance of such Notes does not contravene any provision of Article 4 of the Indenture, and

(2) In the case of Additional Notes, receipt by the Trustee of an Opinion of Counsel confirming that such Additional Notes are fungible with the Initial Notes for U.S. federal income tax purposes. Additional Notes will be fungible with the Initial Notes if they are issued pursuant to a qualified reopening under Treasury Regulations section 1.1275-2(k) for U.S. federal income tax purposes.

(3) An order of the Company to the Trustee to authenticate such Notes.

(4) An Opinion of Counsel per Section 10.04 herein.

SECTION 2.03. Registrar, Paying Agent and Authenticating Agent; Paying Agent to Hold Money in Trust. (a) The Company may appoint one or more Registrars and one or more Paying Agents, in which case each reference in the Indenture to the Trustee in respect of the obligations of the Trustee to be performed by that Agent will be deemed to be references to the Agent. The Company may act as Registrar or (except for purposes of Article 8) Paying Agent. In each case the Company and the Trustee will enter into an appropriate agreement with the Agent implementing the provisions of the Indenture relating to the obligations of the Trustee to be performed by the Agent and the related rights. The Company initially appoints the Trustee as Registrar and Paying Agent.

(b) The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify the Trustee of any default by the Company in making any such payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a Paying Agent, require the Paying

Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no further liability for the money so paid over to the Trustee.

SECTION 2.04. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if a Holder claims that its Note has been lost, destroyed or wrongfully taken, the Company will issue and the Trustee will authenticate a replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. Every replacement Note is an additional obligation of the Company and entitled to the benefits of the Indenture. If required by the Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the Company and the Trustee from any loss they may suffer if a Note is replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay the Note instead of issuing a replacement Note.

SECTION 2.05. Outstanding Notes. (a) Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for:

(i) Notes cancelled by the Trustee or delivered to it for cancellation;

(ii) any Note which has been replaced pursuant to Section 2.04 unless and until the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser; and

(iii) on or after the maturity date or any redemption date or date for purchase of the Notes pursuant to a Change of Control Offer, those Notes payable or to be redeemed or purchased on that date for which the Trustee (or Paying Agent, other than the Company or an Affiliate of the Company) holds money sufficient to pay all amounts then due.

(b) A Note does not cease to be outstanding because the Company or one of its Affiliates holds the Note, provided that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given or taken any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Notes owned by the Company or any Affiliate of the Company will be disregarded and deemed not to be outstanding (it being understood that in determining whether the Trustee is protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other action, only Notes which a Responsible Officer of the Trustee actually knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any Affiliate of the Company.

SECTION 2.06. Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee will authenticate temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have insertions,

substitutions, omissions and other variations determined to be appropriate by the Officer executing the temporary Notes, as evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for the purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender for cancellation of any temporary Notes, the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will be entitled to the same benefits under the Indenture as definitive Notes.

SECTION 2.07. Cancellation. The Company at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or payment. The Trustee will cancel all Notes surrendered for transfer, exchange, payment or cancellation and dispose of them in accordance with its normal procedures or the written instructions of the Company. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

SECTION 2.08. CUSIP and CINS Numbers. The Company in issuing the Notes may use “CUSIP” and “CINS” numbers for the Notes, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption and in Change of Control Offers as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or Change of Control Offer. The Company will promptly notify the Trustee of any change in the CUSIP or CINS numbers.

SECTION 2.09. Registration, Transfer and Exchange. (a) The Notes will be issued in registered form only, without coupons, and except under the circumstances described in subsections (b)(ii) or (b)(iv) of this Section 2.09, the Notes will be issued in global form only. The Company shall cause the Trustee to maintain a register (the “Register”) of the Notes, for registering the record ownership of Notes by the Holders thereof and transfers and exchanges of the Notes.

(b) (i) Each Global Note will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

(ii) Each Global Note will be delivered to the Trustee as custodian for the Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (x) as set forth in Section 2.09(b)(iv) and (y) transfers of portions thereof in the form of Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to

the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section and Section 2.10.

(iii) Agent Members will have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under the Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(iv) If (A) the Depositary (x) notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and in each case a successor depositary is not appointed by the Company within 90 days of that notice or becoming aware that the Depositary is no longer so registered or willing or able to act as a depositary, (B) the Company determines not to have the Notes represented by a Global Note and provides written notice thereof to the Trustee; provided that in no event shall a Temporary Offshore Global Note be exchanged for certificated Notes prior to the expiration of the distribution compliance period and the receipt of any required Regulation S Certificate; or (C) an Event of Default shall have occurred and be continuing with respect to the Notes, the Trustee will promptly exchange each beneficial interest in each Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon each Global Note will be deemed canceled. If a Global Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend. If a Global Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend, provided that any Holder of any such Certificated Note issued in exchange for a beneficial interest in a Temporary Offshore Global Note will have the right upon presentation to the Trustee of a duly completed Certificate of Beneficial Ownership after the Restricted Period to exchange such Certificated Note for a Certificated Note of like tenor and amount that does not bear the Restricted Legend, registered in the name of such Holder.

(c) Each Certificated Note issued pursuant to subsection (b)(iv) will be registered in the name of the Holder thereof or its nominee.

(d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The Trustee will promptly register any

transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that:

(i) no transfer or exchange will be effective until it is registered in such register and

(ii) the Trustee will not be required (x) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or purchased pursuant to a Change of Control Offer, (y) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of any Note not being redeemed or purchased, or (z) if a redemption or a purchase pursuant to a Change of Control Offer is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name any Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

No service charge will be imposed in connection with any transfer or exchange of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(iv)).

(e) (i) Global Note to Global Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(ii) Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer

or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

SECTION 2.10. Restrictions on Transfer and Exchange. (a) The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section and Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of the Depositary. The Trustee shall refuse to register any requested transfer or exchange that does not comply with the preceding sentence.

(b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of the type set forth opposite in column B below may only be made in compliance with the certification requirements (if any) described in the clause of this paragraph set forth opposite in column C below.

In the event that (1) the requested transfer or exchange takes place after the Restricted Period and a duly completed Regulation S Certificate is delivered to the Trustee or (2) a Certificated Note that does not bear the Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the Trustee will deliver a Certificated Note that does not bear the Restricted Legend.

(iv) The Person requesting the transfer or exchange must deliver or cause to be delivered to the Trustee a duly completed Rule 144A Certificate.

(c) No certification is required in connection with any transfer or exchange of any Note (or a beneficial interest therein) after such Note (i) is eligible for resale pursuant to Rule 144 under the Securities Act (or a successor provision); provided that the Company has provided the Trustee with an Officer’s Certificate to that effect, and the Company may require from any Person requesting a transfer or exchange in reliance upon this clause an opinion of counsel and any other reasonable certifications and evidence in order to support such certificate; or

(ii) sold pursuant to an effective registration statement.

Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted Legend.

(d) The Trustee will retain copies of all certificates, opinions and other documents received in connection with the transfer or exchange of a Note (or a beneficial interest therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon reasonable prior written notice to the Trustee.

SECTION 2.11. Temporary Offshore Global Notes. (a) Each Note originally sold by the Initial Purchasers in reliance upon Regulation S will be evidenced by one or more Offshore Global Notes that bear the Temporary Offshore Global Note Legend.

(b) An owner of a beneficial interest in a Temporary Offshore Global Note (or a Person acting on behalf of such an owner) may provide to the Trustee (and the Trustee will accept) a duly completed Certificate of Beneficial Ownership at any time after the Restricted Period (it being understood that the Trustee will not accept any such certificate during the Restricted Period). Promptly after acceptance of a Certificate of Beneficial Ownership with respect to such a beneficial interest, the Trustee will cause such beneficial interest to be exchanged for an equivalent beneficial interest in a Permanent Offshore Global Note, and will (x) permanently reduce the principal amount of such Temporary Offshore Global Note by the amount of such beneficial interest and (y) increase the principal amount of such Permanent Offshore Global Note by the amount of such beneficial interest.

(c) Notwithstanding anything to the contrary contained herein, beneficial interests in a Temporary Offshore Global Note may be held through the Depositary only through Euroclear and Clearstream and their respective direct and indirect participants.

(d) Notwithstanding paragraph (b), if after the Restricted Period any Initial Purchaser owns a beneficial interest in a Temporary Offshore Global Note, such Initial Purchaser may, upon written request to the Trustee accompanied by a certification as to its status as an Initial Purchaser, exchange such beneficial interest for an equivalent beneficial interest in a Permanent Offshore Global Note, and the Trustee will comply with such request and will (x) permanently reduce the principal amount of such Temporary Offshore Global Note by the amount of such beneficial interest and (y) increase the principal amount of such Permanent Offshore Global Note by the amount of such beneficial interest.

Article 3

OPTIONAL REDEMPTION

SECTION 3.01. Optional Redemption. (a) The Notes are subject to redemption upon not less than 30 nor more than 60 days notice mailed to each holder of Notes to be redeemed at its address appearing in the Register, prior to June 15, 2020, at any time in whole or in part, at the election of the Company at a price (the “Redemption Price”) equal to the greater of:

(i) 100% of the principal amount of the Notes being redeemed; or

(ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes being redeemed (excluding interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Rate plus 30 basis points;

plus, for (i) or (ii) above, whichever is applicable, accrued interest on such Notes to, but not including, the date of redemption.

(b) Under the procedures set forth above, the Redemption Price payable upon the optional redemption prior to June 15, 2020 of any Notes called for redemption shall be determined by calculating the present value at that time of each remaining payment of principal of or interest on such Notes and then totaling those present values. If the sum of those present values is equal to or less than 100% of the principal amount of the Notes called for redemption, the Redemption Price of such Notes shall be 100% of its principal amount (redemption at par). If the sum of the present values is greater than 100% of the principal amount of the Notes called for redemption, the Redemption Price of such Notes shall be that greater amount (redemption at a premium). In no event may any Notes be redeemed optionally at less than 100% of their principal amount. The Redemption Price will be calculated by the Quotation Agent and the Company, the Trustee and any Paying Agent will be entitled to rely on such calculation.

(c) At any time on or after June 15, 2020, the Notes will be redeemable in whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the date of redemption

SECTION 3.02. Method and Effect of Redemption. (a) If the Company elects to redeem any Notes, it must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed by delivering an Officers’ Certificate to the Trustee at least 15 days prior to the date of the mailing of the notice (unless a shorter period is satisfactory to the Trustee in the sole determination of the Trustee). If fewer than all of the Notes are being redeemed, the Officers’ Certificate must also specify a record date not less than 15 days after the date of the notice of redemption is given to the Trustee, and the Trustee will select the Notes to be redeemed pro rata, by lot or by any other method the Trustee in its sole discretion deems appropriate, in denominations of $1,000 principal amount and multiples thereof. The Trustee will notify the

Company promptly of the Notes or portions of Notes to be called for redemption. Notice of redemption must be sent by the Company or at the Company’s request (the Company to provide or cause to be provided to the Trustee such information to be included in such notice five (5) days prior to such notice being sent to Holders, unless a shorter period is satisfactory to the Trustee, in the sole determination of the Trustee), by the Trustee in the name and at the expense of the Company, to Holders whose Notes are to be redeemed at least 30 days but not more than 60 days before the redemption date.

(b) The notice of redemption will identify the Notes to be redeemed and will include or state the following:

(i) the redemption date;

(ii) the Redemption Price, including the portion thereof representing any accrued interest;

(iii) the place or places where Notes are to be surrendered for redemption;

(iv) Notes called for redemption must be so surrendered in order to collect the Redemption Price;

(v) on the redemption date the Redemption Price will become due and payable on Notes called for redemption, and interest on Notes called for redemption will cease to accrue on and after the redemption date;

(vi) if any Note is redeemed in part, on and after the redemption date, upon surrender of such Note, new Notes equal in principal amount to the unredeemed portion will be issued; and

(vii) if any Note contains a CUSIP or CINS number, no representation is being made as to the correctness of the CUSIP or CINS number either as printed on the Notes or as contained in the notice of redemption and that the Holder should rely only on the other identification numbers printed on the Notes.

(c) Once notice of redemption is sent to the Holders, Notes called for redemption become due and payable at the Redemption Price on the redemption date, and upon surrender of the Notes called for redemption, the Company shall redeem such Notes at the Redemption Price. Commencing on the redemption date, Notes redeemed will cease to accrue interest. Upon surrender of any Note redeemed in part, the Holder will receive a new Note equal in principal amount to the unredeemed portion of the surrendered Note.

SECTION 3.03. Sinking Fund. No sinking fund is provided for the Notes.

Article 4

COVENANTS

In each case the Company will promptly notify the Trustee of its compliance with this paragraph.

(b) An installment of principal or interest will be considered paid on the date due if the Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds on that date money designated for and sufficient to pay the installment. If the Company or any Affiliate of the Company acts as Paying Agent, an installment of principal or interest will be considered paid on the due date only if paid to the Holders.

(c) The Company agrees to pay interest on overdue principal, and, to the extent lawful, overdue installments of interest at the rate per annum specified in the Notes.

(d) Payments in respect of the Notes represented by the Global Notes are to be made by electronic funds transfer of immediately available funds to the accounts specified by the Holders of the Global Notes.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be surrendered or presented for any of such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 4.03. Limitations on Liens. (a) Liens on the IPL Stock. The Company may not secure any Indebtedness of any Person, other than IPALCO Indebtedness, by a Lien upon any common stock of IPL.

(b) Liens on Property or Assets other than the IPL Stock. Neither the Company nor any Significant Subsidiary shall issue, assume or guarantee any Indebtedness secured by a Lien upon any property or assets (other than any capital stock of IPL or cash or cash equivalents) of the Company or such Significant Subsidiary, as applicable, without effectively providing that the outstanding Notes (together with, if the Company so determines, any other Indebtedness or obligation then existing or thereafter created ranking equally with the Notes) will be secured equally and ratably with (or prior to) such Indebtedness so long as such Indebtedness is so secured. The foregoing limitation on Liens of this clause (b) will not, however, apply to:

(i) Liens in existence on the Issue Date;

The Company shall also notify the Trustee of any Default or Event of Default under this Indenture, provided, however, that a failure by the Company to deliver such notice shall not constitute a Default or an Event of Default under this Indenture, if the Company has remedied such Default within any applicable grace period.

SECTION 4.06. Reports by the Company. (a) So long as the Company is required to be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall provide copies to the Trustee with the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

Article 6

Default and Remedies

SECTION 6.01. Events of Default. An “Event of Default” occurs with respect to the Notes if:

(i) the Company defaults in the payment of the principal of, or any premium on, any Note when the same becomes due and payable at maturity, upon acceleration, redemption or required purchase or otherwise;

(ii) the Company defaults in the payment of interest on any Note when the same becomes due and payable, and the default continues for a period of 30 days;

(iii) the Company defaults in the performance of or breaches any other covenant or agreement of the Company in the Indenture or under the Notes and the default or breach continues for a period of 30 consecutive days after written notice specifying the default is delivered to the Company by the Trustee or to the Company and the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes;

(iv) a default occurs in the payment of the principal of any bond, debenture, note or other evidence of indebtedness, in each case for money borrowed, issued by the Company, or in the payment of principal under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for Borrowed Money, of the Company or any Significant Subsidiary if such Indebtedness for Borrowed Money is not Project Finance Debt and provides for recourse generally to the Company or any Significant Subsidiary, which default for payment of principal is in an aggregate principal amount exceeding $40 million when such indebtedness becomes due and payable (whether at maturity, upon redemption or acceleration or otherwise), if such default shall continue unremedied or unwaived for more than 30 Business Days and the time for payment of such amount has not been expressly extended (until such time as such payment default is remedied, cured or waived);

(v) a court having jurisdiction enters a decree or order for: (i) relief in respect of the Company or any of its Significant Subsidiaries in an involuntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect; (ii) appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of the Company or any of its Significant Subsidiaries or for all or substantially all of the property and assets of the Company or any of its Significant Subsidiaries; or (iii) the winding up or liquidation of the affairs of the Company or any of its Significant Subsidiaries; and, in each case, such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(vi) the Company or any of its Significant Subsidiaries: (i) commences a voluntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect, or consents to the entry of an order for relief in an involuntary case under any such law; (ii) consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of the Company or any of its Significant Subsidiaries or for all or substantially all of the property and assets of the Company or any of its Significant Subsidiaries; or (iii) effects any general assignment for the benefit of creditors (an event of default specified in clause (v) or (vi) a “Bankruptcy Default”); or

(vii) the Collateral Agent fails to have a perfected security interest in the Pledged Stock of IPL for a period of 10 days.

SECTION 6.02. Acceleration. (a) If an Event of Default, other than a Bankruptcy Default with respect to the Company, occurs with respect to the Notes and is continuing under the Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Company (and to the Trustee if the notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest on the outstanding Notes to be immediately due and payable. Upon a declaration of acceleration, such principal, premium, if any, and accrued interest will become immediately due and payable. If a Bankruptcy Default occurs with respect to the Company, the principal of, premium, if any, and accrued interest on the Notes then outstanding will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b) The Holders of a majority in principal amount of the outstanding Notes by written notice to the Company and to the Trustee may waive all past defaults with respect to the Notes and rescind and annul a declaration of acceleration with respect to the Notes and its consequences if:

(i) all existing Events of Default applicable to the Notes, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration, have been cured or waived; and

(ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

SECTION 6.03. Other Remedies. If an Event of Default with respect to the Notes occurs and is continuing, the Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or the Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. When the Trustee Incurs expenses or renders services after the occurrence of an act of bankruptcy with respect to the Company, the expenses and the compensation for such services are intended to constitute expenses of administration under any federal or state bankruptcy, insolvency, arrangement, moratorium, reorganization or other debtor relief law.

SECTION 6.04. Waiver of Past Defaults. Except as otherwise provided in Sections 6.02, 6.07 and 9.02, the Holders of a majority in principal amount of outstanding Notes may, by notice to the Trustee, waive an existing Default with respect to the Notes and its consequences. Upon such waiver, the Default with respect to the Notes will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 6.05. Control by Majority. The Holders of at least a majority in aggregate principal amount of outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of the Notes not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of the Notes.

SECTION 6.06. Limitation on Suits. A Holder of the Notes may not institute any proceeding, judicial or otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy under the Indenture or the Notes, unless:

(i) such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes;

(ii) the Holders of at least 25% in aggregate principal amount of outstanding Notes have made written request to a Responsible Officer of the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under the Indenture;

(iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liabilities or expenses to be Incurred in compliance with such request;

(iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(v) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes have not given the Trustee a direction that is inconsistent with such written request.

SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding anything to the contrary, the right of a Holder of a Note to receive payment of principal of, premium, if any, or interest on its Note on or after the stated maturities thereof, or to bring suit for the enforcement of any such payment on or after such respective dates, may not be impaired or affected without the consent of that Holder.

SECTION 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in clause (1) or (2) of Section 6.01 occurs and

is continuing with respect to the Notes, the Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal, premium, if any, and accrued interest remaining unpaid on the Notes, together with interest on overdue principal and, to the lawful, overdue installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders allowed in any judicial proceedings relating to the Company or its creditors or property, and is entitled and empowered to collect, receive and distribute any money, securities or other property payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee hereunder. Nothing in the Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article, it shall payout the money in the following order:

First: to the Trustee for all amounts due to the Trustee hereunder;

Second: to Holders of the Notes in respect of which moneys have been collected for amounts then due and unpaid for principal of, premium, if any, and interest on such Notes, ratably, without preference or priority of any kind of any Note over any other Note, according to the amounts due and payable on such Notes for principal, premium, if any, and interest; and

Third: to the Company or as a court of competent jurisdiction may direct in a final, non-appealable order.

The Trustee, upon written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section.

SECTION 6.11. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding,

the Company, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company, the Trustee and the Holders will continue as though no such proceeding had been instituted.

SECTION 6.12. Undertaking for Costs. In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys fees and expenses, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the outstanding Notes.

SECTION 6.13. Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this Indenture is intended to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other right or remedy.

SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 6.15. Waiver of Stay, Extension or Usury Laws. The Company covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the Indenture. The Company hereby expressly waives, to the extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Article 7

The Trustee

SECTION 7.01. General. (a) The duties and responsibilities of the Trustee are as provided by the Trust Indenture Act and as set forth herein. Whether or not expressly so

provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee is subject to this Article.

(b) Except during the continuance of an Event of Default, the Trustee needs to perform only those duties that are specifically set forth in the Indenture and no others, and no implied covenants or obligations will be read into the Indenture against the Trustee. In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). In case an Event of Default has occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of the Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that

(1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Notes relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it

SECTION 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act Sections 315(a) through (d):

(i) In the absence of bad faith on its part, the Trustee may conclusively rely, and will be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,

consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Trustee pursuant to any provision hereof, the Trustee shall examine the document to determine whether it conforms to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Trustee, in its discretion, may make further inquiry or investigation into such facts or matters as it sees fit and shall Incur no liability of any kind by reason of such inquiry or investigation.

(ii) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel conforming to Section 10.05 and the Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the certificate or opinion.

(iii) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.

(iv) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of the Notes, unless such Holders have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that might be Incurred by it in compliance with such request or direction.

(v) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the direction of the Holders of the Notes in accordance with Section 6.05 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under the Indenture.

(vi) The Trustee may consult with counsel of its selection, and the advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(vii) No provision of the Indenture will require the Trustee to expend or risk its own funds or otherwise Incur any financial liability in the performance of its duties hereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense.

SECTION 7.05. Notice of Default. If any Default with respect to the Notes occurs and is continuing and is known to the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it occurs, unless the Default has been cured; provided that,

except in the case of a default in the payment of the principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors of the Trustee in good faith determines that withholding the notice is in the interest of the Holders of the Notes.

(d) When the Trustee incurs expenses or renders services in connection with an Event of Default, 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.

Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its written acceptance within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of all then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

(c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the retiring Trustee and to the Company, (i) the retiring Trustee upon payment of its charges hereunder will transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, (ii) the resignation or removal of the retiring Trustee will become effective, and (iii) the successor Trustee will have all the rights, powers and duties of the Trustee under the Indenture.

Article 9

Amendments, Supplements and Waivers

(i) to cure any ambiguity, defect or inconsistency in the Indenture or the Notes;

(vi) to provide for any guarantee of the Notes, to secure-the Notes or to confirm and evidence the release, termination or discharge of any guarantee of or lien securing the Notes when such release, termination or discharge is permitted by the Indenture;

or

(viii) to make any other change that does not materially and adversely affect the rights of any Holder.

(b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder of Notes affected, an amendment or waiver may not:

(i) reduce the principal amount of or change the stated maturity of any installment of principal of any Note;

(ii) reduce the rate of or change the stated maturity of any interest payment on any Note;

(iii) reduce the amount payable upon the redemption or any required repurchase of any Note or change the times at which any Note may be redeemed or repurchased or, once notice of redemption or a Change of Control Offer has been given, the time at which it must thereupon be redeemed or repurchased;

(iv) make any Note payable in money other than that stated in such Note;

(v) impair the right of any Holder of Notes to receive any principal payment, premium payment, if any, or interest payment on such Holder’s Notes, on or after the stated maturity thereof, or to institute suit for the enforcement of any such payment;

After an amendment, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. The Company will send supplemental indentures to Holders upon request.

However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

SECTION 9.04. Trustee’s Rights and Obligations. The Trustee shall be provided with, and will be fully protected in relying upon, an Opinion of Counsel and an Officer’s Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by the Indenture. Upon receipt of such an Opinion of Counsel and Officer’s Certificate, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights, duties or immunities under the Indenture.

SECTION 9.06. Payments for Consents. Neither the Company nor any of its Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture with respect to the Notes or the Notes unless such consideration is offered to be paid, or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.
