However, if fewer than three banks selected by the Calculation Agent to provide quotations are quoting as described above, Three-month LIBOR for that Interest Period will be the same as Three-month LIBOR as determined for the previous Interest Period or, in the case of the Interest Period beginning on the Scheduled Maturity Date, 5.36%.

     “Voting Stock” means equity securities which ordinarily have voting power for the election of directors, whether at all times or only so long as no senior class of equity securities has such voting power by reason of any contingency.

     (b) “Applicable Percentage”, “Intent-Based Replacement Disclosure”, “Permitted Remedies” and “Qualifying Capital Securities” shall have the respective meanings set forth in the Replacement Capital Covenant as in effect on the date hereof and as it may be amended pursuant to its terms consistent with Section 2.1(r).

For the purpose of clarity, it is possible that the Company may repay the principal and current interest on a Debenture pursuant to this Section 2.1(d) but still be obligated to pay deferred interest on the Debenture.

     (A) to raise sufficient Eligible Repayment Proceeds during a 180-day period ending on a date not more than 30 and not less than 10 Business Days prior to the Scheduled Maturity Date to permit repayment of the principal and current interest on all Outstanding Debentures in full on the Scheduled Maturity Date; and

     (B) if the Company is unable for any reason to raise sufficient Eligible Repayment Proceeds to permit repayment in full of the principal amount of and current interest on all the Outstanding Debentures on the Scheduled Maturity Date or any subsequent Interest Payment Date, to raise sufficient Eligible Repayment Proceeds to permit repayment of the principal and current interest on all Outstanding Debentures in full on the next Interest Payment Date pursuant to clause (ii) of this Section 2.1(d).

     (vi) The Company shall, if it has not raised sufficient Eligible Repayment Proceeds in connection with any Repayment Date, deliver an Officers’ Certificate to the Trustee no more than 30 and no less than 10 Business Days in advance of such Repayment Date stating the amount of Eligible Repayment Proceeds, if any, raised pursuant to clause (v) above in connection with such Repayment Date. Each Officers’ Certificate delivered pursuant to this clause (vi), unless no principal amount of Debentures is to be repaid on the applicable Repayment Date, shall be accompanied by a notice of repayment pursuant to Section 3.1 setting forth the principal amount of the Debentures to be repaid on such Repayment Date, which amount shall be determined after giving effect to clause (viii) of this Section 2.1(d).

     (vii) The Company shall be excused from its obligation to use Commercially Reasonable Efforts to sell Qualifying Capital Securities pursuant to clause (v) above if such Officers’ Certificate further certifies that: (A) a Market Disruption Event was existing at any time during the period commencing 180 days prior to the date of such Officers’ Certificate or, in the case of any Repayment Date after the Scheduled Maturity Date, the period commencing on the immediately preceding Interest Payment Date and ending on the Business Day immediately preceding the date of such Officers’ Certificate; and (B) either (1) the Market Disruption Event continued for the entire 180-day period or, in the case of any Repayment Date after the Scheduled Maturity Date, the period since the most recent Interest Payment Date, as the case may be, or (2) the Market Disruption Event continued for only part of the relevant period, but the Company was unable after Commercially Reasonable Efforts to raise sufficient Eligible Repayment Proceeds during the rest of that period to permit repayment of the Debentures in full.

     (viii) Payments on the Debentures on any Repayment Date shall be applied, first, to the extent permitted by Section 2.1(i), to deferred interest to the extent of Eligible APM Proceeds raised pursuant to Section 2.1(i), second, to current interest and, third, to the repayment of the principal of Debentures; provided that if the Company is obligated to sell Qualifying Capital Securities and repay any outstanding pari passu securities in addition to the Debentures, then on any date and for any period such payments shall be applied (A) first, to Outstanding Parity Securities and any other pari passu securities having an earlier scheduled maturity date than the Debentures, until the principal of and all accrued and unpaid interest on those securities has been paid in full, and (B) second, to the Debentures and any Outstanding Parity Securities or other pari passu securities having the same scheduled maturity date as the Debentures pro rata in accordance with their respective outstanding principal amounts. None of such payments shall be applied to any other pari passu securities having a later scheduled maturity date until the principal of and all accrued and unpaid interest on the Debentures has been paid in full, except to the extent permitted by clause (vii) of Section 2.1(g) and the first sentence of Section 2.1(h). If the Company has raised less than $5,000,000 of Eligible Repayment Proceeds during the relevant 180-day or three-month period, the Company will not be required to repay any Debentures on the relevant Repayment Date, but it will repay the applicable principal amount of the Debentures on the next Interest Payment Date as of which the Company has raised at least $5,000,000 of Eligible Repayment Proceeds.

     (e) Rate of Interest. The Debentures shall bear interest (i) from and including June 7, 2007 to but excluding the Scheduled Maturity Date at the rate of 6.45% per annum, computed on the basis of a 360-day year comprised of twelve 30-day months, and (ii) thereafter, as to the principal amount of any Outstanding Debentures, at an annual rate equal to Three-month LIBOR plus 1.82%, computed on the basis of a 360-day year and the actual number of days elapsed. All percentages resulting from any calculation of

Three-month LIBOR will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. Subject to Sections 2.1(g) and (h): interest on the Debentures shall be payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, beginning on September 15, 2007 (each such date, an “Interest Payment Date”). In the event any Interest Payment Date on or before the Scheduled Maturity Date falls on a day that is not a Business Day, the interest payment due on that date will be postponed to the next day that is a Business Day and no interest shall accrue as a result of such postponement. If any Interest Payment Date after the Scheduled Maturity Date would otherwise fall on a day that is not a Business Day, such Interest Payment Date will be postponed to the following Business Day, unless such postponement would cause the day to fall in the next calendar month, in which case it shall be brought forward to the immediately preceding Business Day. Any installment of interest (or portion thereof) deferred in accordance with Section 2.1(g) or otherwise unpaid shall bear additional interest, to the extent permitted by law, at the rate of interest then in effect from time to time on the Debentures, from the relevant Interest Payment Date, compounded on each subsequent Interest Payment Date, until paid in accordance with Section 2.1(h).

     (f) To Whom Interest is Payable. Interest (other than deferred interest which shall be payable to the Persons specified pursuant to Section 2.1(g)(ii)) shall be payable to the Person in whose name the Debentures are registered at the close of business on the Business Day next preceding the Interest Payment Date, or in the event the Debentures cease to be held in the form of one or more Global Securities, at the close of business on the date 15 days prior to that Interest Payment Date, whether or not a Business Day.

     (g) Option to Defer Interest Payments.

     (i) The Company shall have the right, at any time and from time to time prior to the Final Maturity Date, to defer the payment of interest on the Debentures for up to 40 consecutive Interest Periods; provided that no Deferral Period shall extend beyond the Final Maturity Date or the earlier redemption of the Debentures. If an Event of Default has occurred and is continuing or the Company has given notice of its election to defer interest payments but the Deferral Period has not yet commenced or a Deferral Period is continuing, the Company shall not, and shall not permit any Subsidiary, subject to the exceptions specified in clause (vii) of this Section 2.1(g), to: (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any Capital Stock of the Company, (b) make any payment of principal of, or interest or premium, if any, on, or repay, purchase or redeem any debt securities of the Company that rank pari passu with or junior to the Debentures or (c) make any payments with respect to any Guarantee by the Company of securities of any Subsidiary if such Guarantee ranks pari passu with, or junior to, the Debentures.

     (ii) At the end of any Deferral Period, the Company shall pay all deferred interest on the Debentures (together with compounded interest thereon, if any, to the extent permitted by applicable law), to the Person in whose name the Debentures are registered at the close of business on the Business Day next preceding the Interest Payment Date at the end of such Deferral Period or, in the event the Debentures cease to be held in the form of one or more Global Securities, at the close of business on the date 15 days prior to the end of the Deferral Period, whether or not a Business Day.

     (iii) Upon termination of any Deferral Period and upon the payment of all deferred interest and any compounded interest then due on any Interest Payment Date, the Company may elect to begin a new Deferral Period pursuant to clause (i) of this Section 2.1(g).

     (iv) The Company may elect to pay deferred interest on any Interest Payment Date during any Deferral Period to the extent permitted by Section 2.1(h).

     (v) The Company shall give written notice to the Trustee and the Holders of the Debentures of its election to begin any Deferral Period at least one Business Day prior to the Regular Record Date for that Interest Payment Date. Notwithstanding the previous sentence, the Company’s failure to pay any interest due within five Business Days after any Interest Payment Date shall automatically and without any further action by any Person be deemed to commence a Deferral Period.

     (vi) If any Deferral Period lasts longer than one year, the Company shall not, and shall cause its Subsidiaries not to, purchase, redeem or otherwise acquire any securities ranking junior to or pari passu with any APM Qualifying Securities the proceeds of which were used to pay deferred interest during such Deferral Period until the first anniversary of the date on which all deferred interest has been paid, subject to the exceptions set forth in clause (vii) below. If the Company is involved in a Business Combination where immediately after the consummation of the Business Combination more than 50% of the surviving or resulting entity’s Voting Stock is owned by the shareholders of the other party to the Business Combination or Continuing Directors cease for any reason to constitute a majority of the directors of the surviving or resulting entity, then neither the restrictions set forth in this clause (vi) nor the provisions of Section 2.1(h) shall apply to any Deferral Period that is terminated on the next Interest Payment Date following the date of consummation of the Business Combination.

     (vii) The restrictions in clauses (i) and (vi) of this Section 2.1(g) do not apply to (a) purchases, redemptions or other acquisitions of shares of the Company’s Capital Stock in connection with (1) any Employee Benefit Plan or the Assurance Agreement or (2) a dividend reinvestment, stock purchase plan or

other similar plan, (b) any exchange or conversion of any class or series of the Company’s Capital Stock (or the Capital Stock of any Subsidiary) for any class or series of the Company’s Capital Stock or of any class or series of Indebtedness of the Company for any class or series of the Company’s Capital Stock, (c) the purchase of fractional interests in shares of the Capital Stock of the Company in accordance with the conversion or exchange provisions of the Company’s Capital Stock or the security or instrument being converted or exchanged, (d) any declaration of a dividend in connection with any stockholders’ right plan, or the issuance of rights, equity securities or other property under any stockholders’ right plan, or the redemption or repurchase of rights in accordance with any stockholders’ rights plan, (e) any dividend in the form of equity securities, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of the warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such equity securities, (f) any payment during a Deferral Period of current or deferred interest in respect of any debt securities of the Company that rank pari passu with the Debentures that is made pro rata to the amounts due on pari passu securities and the Debentures (provided that such payments are made in accordance with Section 2.1(h) to the extent it applies) and any payments of deferred interest on such pari passu securities that, if not made, would cause the Company to breach the terms of the instrument governing such pari passu securities, (g) any payment of principal in respect of pari passu securities having an earlier scheduled maturity date than the Debentures, as required under a provision of such pari passu securities that is substantially the same as Section 2.1(d) or any such payment in respect of any such pari passu securities having the same scheduled maturity date as the Debentures that is made on a pro rata basis among one or more series of such securities and the Debentures or (h) any repayment or redemption of a security necessary to avoid a breach of the instrument governing that security.

     (h) Payment of Deferred Interest. The Company shall not pay deferred interest (including compounded interest thereon) on the Debentures on any Interest Payment Date during any Deferral Period from any source other than Eligible APM Proceeds unless (x) required by an applicable regulatory authority, (y) permitted under clause (vi) of Section 2.1(g) or (z) an Event of Default has occurred and is continuing. Notwithstanding the foregoing, the Company may pay current interest during a Deferral Period from any available funds. To the extent that the Company is able to raise some, but not all, Eligible APM Proceeds to pay accrued and unpaid interest on the applicable Interest Payment Date, such Eligible APM Proceeds shall be allocated first to deferred payments of accrued and unpaid interest in chronological order based on the date each payment was first deferred. If any Indebtedness of the Company that ranks pari passu with the Debentures is outstanding in addition to the Debentures under which the Company is obligated to sell APM Qualifying Securities and apply the net proceeds to the payment of deferred interest or distributions, then on any date and for any period the amount of Eligible APM Proceeds received by the Company from such sales and

available for payment of the deferred interest and distributions shall be applied to the Debentures and such pari passu securities on a pro rata basis up to, in the case of Common Stock, the Stock and Warrant Issuance Cap and the Maximum Share Number, in the case of Qualifying Warrants, the Stock and Warrant Issuance Cap and the Maximum Warrant Number and, in the case of Qualifying Non-Cumulative Preferred Stock, the Preferred Stock Issuance Cap (or comparable provisions in the instruments governing such pari passu securities) in proportion to the total amounts that are due on the Debentures and such pari passu securities. The Company may make such pro rata payments on such pari passu securities so long as it shall have paid or deposited with the paying agent for the Debentures or shall have segregated and holds in trust for payment the pro rata proceeds applicable to the Debentures that have not been paid. The “Maximum Share Number” will initially equal 100,000,000 and the “Maximum Warrant Number” will initially equal 100,000,000; provided that, if the number of issued and outstanding shares of Common Stock is changed into a different number of shares or a different class by reason of any stock split, reverse stock split, stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or other similar transaction, then the Maximum Share Number and the Maximum Warrant Number shall be correspondingly adjusted in a manner reasonably determined by the Company. The Company may, at its discretion and without the consent of the holders of the Debentures, increase the Maximum Share Number or the Maximum Warrant Number or both (including through the increase of the Company’s authorized share capital, if necessary) if the Company determines that such increase is necessary to allow the Company to issue sufficient Common Stock and/or Qualifying Warrants to pay deferred interest on the Debentures.

     (i) Alternative Payment Mechanism. Immediately following any APM Commencement Date and until the termination of the related Deferral Period, the Company will be required to use Commercially Reasonable Efforts to sell APM Qualifying Securities until the Company has raised an amount of Eligible APM Proceeds at least equal to the aggregate amount of accrued and unpaid deferred interest on the Debentures (including compounded interest thereon) and applied such Eligible APM Proceeds on the next Interest Payment Date to the payment of deferred interest (including compounded interest thereon) in accordance with Section 2.1(h); provided that:

     (1) the foregoing obligations shall not apply (i) to the issuance of Common Stock and Qualifying Warrants during the first 20 consecutive Interest Periods of any Deferral Period to the extent the number of shares of Common Stock issued and the number of shares of Common Stock subject to such Qualifying Warrants, together with the number of shares of Common Stock previously issued and the number of shares of Common Stock subject to Qualifying Warrants previously issued during such Deferral Period to pay interest on the Debentures pursuant to this Section 2.1(i), would, in the aggregate, exceed 2% of the total number of issued and outstanding shares of Common Stock as of the date of the Company’s most recent publicly available consolidated financial statements on the date of determination (the “Stock and Warrant Issuance Cap”)

or (ii) to the issuance of Qualifying Non-Cumulative Preferred Stock at any time to the extent the Eligible APM Proceeds raised from such issuance, together with the Eligible APM Proceeds of all prior issuances of Qualifying Non-Cumulative Preferred Stock pursuant to this Section 2.1(i) applied to pay deferred interest on the Debentures, would exceed $187,500,000 plus 25% of the sum of (i) the aggregate principal amount of any Debentures issued upon exercise of the underwriters’ over-allotment option referred to in Section 2.1(b) and (ii) the aggregate principal amount of any Additional Debentures issued pursuant to Section 2.1(b) (the “Preferred Stock Issuance Cap”);

     (2) the foregoing obligations shall not apply in respect of any Interest Payment Date if the Company shall have provided to the Trustee (which the Trustee will promptly forward upon receipt to each Holder of the Debentures whose name appears in the Security Register) no more than 30 and no less than 10 Business Days prior to such Interest Payment Date an Officers’ Certificate stating that (i) a Market Disruption Event occurred after the immediately preceding Interest Payment Date and (ii) either (A) the Market Disruption Event continued for the entire period from the Business Day immediately following the preceding Interest Payment Date to the Business Day immediately preceding the date on which such Officers’ Certificate is provided or (B) the Market Disruption Event continued for only part of such period but the Company was unable after Commercially Reasonable Efforts to raise sufficient Eligible APM Proceeds during the rest of that period to pay all accrued and unpaid interest due on the Interest Payment Date with respect to which such Officers’ Certificate is being delivered; and

     (3) to the extent that the Company has raised some but not all Eligible APM Proceeds necessary to pay all deferred interest on any Interest Payment Date, such Eligible APM Proceeds shall be applied in accordance with Section 2.1(h).

     Once the Company reaches the Stock and Warrant Issuance Cap for a Deferral Period, the Company will not be required to issue more shares of Common Stock or Qualifying Warrants under this Section 2.1(i) during the first 20 consecutive Interest Periods of such Deferral Period even if the Stock and Warrant Issuance Cap subsequently increases because of a subsequent increase in the number of outstanding shares of Common Stock. The Stock and Warrant Issuance Cap will cease to apply after the conclusion of 20 consecutive Interest Periods following the commencement of any Deferral Period, at which point the Company must pay any deferred interest, regardless of the time at which it was deferred pursuant to Section 2.1(h), subject to the limitations in Section 2.1(g), the Preferred Stock Issuance Cap, the Maximum Share Number, the Maximum Warrant Number and any Market Disruption Event. In addition, if the Stock and Warrant Issuance Cap is reached during a Deferral Period and the Company subsequently pays all deferred interest, the Stock and Warrant Issuance Cap will cease to apply at the termination of such Deferral Period, reset to zero and will not apply again

unless and until the start of a new Deferral Period. The Preferred Stock Issuance Cap shall not reset to zero even if the Company pays all deferred interest for a Deferral Period, and the Eligible APM Proceeds from sales of Qualifying Non-Cumulative Preferred Stock applied pursuant to Section 2.1(h) during such Deferral Period and all prior Deferral Periods cumulate as Qualifying Non-Cumulative Preferred Stock is issued to pay deferred interest. The Company will not be excused from its obligations under this Section 2.1(i) if it determines not to pursue or complete the sale of APM Qualifying Securities due to pricing, dividend rate or dilution considerations.

     (j) Events of Default. The Debentures shall not be entitled to the benefits of the Events of Default in clauses (1) through (4) of Section 501 of the Indenture. The Debentures shall be entitled to the benefits of the Events of Default in clauses (5) and (6) of Section 501 of the Indenture. The following events shall be Events of Default with respect to the Debentures (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Fourteen of the Indenture or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

     (1) default in the payment of interest, including compounded interest, in full on any Debenture for a period of 30 days after the conclusion of 40 consecutive Interest Periods following the commencement of any Deferral Period;

     (2) default in the payment of the principal of the Debentures at the Final Maturity Date or upon a call for redemption;

Except as provided in this paragraph (j), no breach or default by the Company of any other covenant or obligation under the Indenture or the terms of the Debentures shall constitute an Event of Default.

     (k) Acceleration of Maturity; Rescission of Amendment. The remedies provided to the Trustee and Holders by Section 502 of the Indenture will apply only to an Event of Default under clause (1) of Section 2.1(j). If an Event of Default specified in Section 501(5) or 501(6) of the Indenture occurs, then in every such case the principal amount of all the Debentures shall automatically become due and payable immediately, without any declaration or other action on the part of the Trustee or any Holder. An Event of Default in clause (2) of Section 2.1(j) shall not entitle the Holders to the benefits of Section 502 of the Indenture.

     (l) Collection of Indebtedness and Suits From Enforcement by Trustee. The Debentures shall not have the benefits of the first paragraph of Section 503 of the Indenture.

     (m) Limitation on Suits. For purposes of the Debentures, Section 507 of the Indenture is hereby amended (i) by adding “or Enforcement Event” after “Event of Default” in clause (1) thereof, and (ii) by adding at the end of clause (2) thereof: “or the

Holders of no less than a majority in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Enforcement Event in its own name as Trustee hereunder;”

     (n) Unconditional Right of Holders to Receive Principal, Premium and Interest. For purposes of the Debentures, Section 508 of the Indenture is hereby amended and restated in its entirety:

“Notwithstanding any other provision in this Indenture or the Fourth Supplemental Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 2.1(g)(ii) of the Fourth Supplemental Indenture and Section 307 of the Indenture) interest on such Debenture when due, it being understood (i) that, in the case of a Deferral Period, interest shall only become due and payable at the time and in the manner provided for in Sections 2.1(g) and (h) of the Fourth Supplemental Indenture, and interest shall, in the case of Section 2.1(i) of the Fourth Supplemental Indenture, only become due and payable in the amount determined in accordance with such Section, and (ii) that the extent to which Holders have a right to receive payment of principal on any Repayment Date is determined in accordance with Section 2.1(d) of the Fourth Supplemental Indenture. Any Holder’s right to institute suit for the enforcement of any such payment, and such rights referred to in this Section 508 shall not be impaired without the consent of such Holder.”

For the purposes of Section 316(b) of the Trust Indenture Act, it is understood and agreed that no payment of principal or interest shall be deemed due and payable under the provisions of Sections 2.1(d), 2.1(g)(ii) and 2.1(h) until the Company has received Eligible Repayment Proceeds or Eligible APM Proceeds, respectively, to pay such principal or interest.

     (o) Waiver of Past Defaults. Notwithstanding anything to the contrary in Section 513 of the Indenture, for the purposes of the Debentures, a past default that is an Event of Default under Section 501(5) or 501(6) of the Indenture cannot be waived, with respect to the Debentures and its consequences, without the consent of each Holder of the Debentures.

     (p) Notice of Defaults and Enforcement Events. For purposes of the Debentures, Section 602 of the Indenture is hereby amended (i) by adding “and Enforcement Events” after “Defaults” in the header thereof, and (ii) by adding “or Enforcement Event” after “default” in the first and second line of such Section.

     (q) Redemption. The Debentures shall be redeemable in accordance with Article Eleven of the Indenture, provided that the Debentures are redeemable at the Company’s option, (i) in whole or in part on any Interest Payment Date on or after June 15, 2012, at 100% of their principal amount, (ii) in whole but not in part at any time prior to June 15, 2012 upon the occurrence of a Tax Event at 100% of their principal amount

and (iii) in whole but not in part at any time prior to June 15, 2012 upon the occurrence of a Rating Agency Event at (1) 100% of their principal amount or (2) if greater, the Make-Whole Redemption Price, in the case of each of clauses (i) through (iii) plus accrued and unpaid interest to the Redemption Date. For purposes of the Debentures, the first sentence of Section 1104 of the Indenture is replaced in its entirety with the following: “Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 10 nor more than 60 days prior to the Redemption Date, to each Holders of Securities to be redeemed, at his address appearing in the Security Register.”

     (r) Replacement Capital Covenant. The Company shall not modify the Replacement Capital Covenant to (A) amend the definitions incorporated into this Fourth Supplemental Indenture pursuant to Section 1.2.3(b) in a manner adverse to the Holders or (B) impose additional restrictions on the type or amount of Qualifying Capital Securities that the Company may include for purposes of determining the extent to which repayment, redemption, defeasance or repurchase of the Debentures is permitted, except with the consent of the holders of a majority of the principal amount of Outstanding Debentures. Except as expressly provided in the preceding sentence, the Company may modify the Replacement Capital Covenant at any time and in any manner without the consent of the Holders of the Debentures.

     (s) Limitation on Claims in the Event of Bankruptcy, Insolvency or Receivership. To the extent permitted by law, each Holder, by such Holder’s acceptance of the Debentures, agrees that if a Bankruptcy Event shall occur prior to the redemption, repayment or defeasance of such Debentures, such Holder shall only have a claim for deferred and unpaid interest (including compounded interest thereon) to the extent such interest (including compounded interest thereon) relates to the earliest two years of the portion of the Deferral Period for which interest has not been paid.

     (t) Sinking Fund; Holder Repurchase Right. The Debentures shall not be subject to any sinking fund or analogous provision or be redeemable at the option of the Holders.

     (u) Forms. The Debentures shall be substantially in the form of Annex A attached hereto, with such modifications thereto as may be approved by the authorized officer executing the same.

     (v) Subordination. The Debentures shall be subject to Article XIV of the Indenture, subject to the following modifications:

     (i) For purposes of the Debentures, the “or” before clause (iii) of the definition of Senior Debt in the Indenture is deleted, the following clauses are added to the definition of Senior Debt in the Indenture after the word “contracts,” in clause (iii) for purposes of the Debentures:

     “, (iv) any subordinated or junior subordinated debt that by its terms is not expressly pari passu or subordinated to the Debentures, (v) any Guarantee of any

indebtedness, obligation or security issued by any Person that is an Affiliate of the Company and such Person is viewed by the Company as a vehicle to finance its operations, and (vi) Indebtedness of the Company to its Subsidiaries”; and

     (ii) For purposes of the Debentures, the following provision is added to the end of the definition of Senior Debt in the Indenture after the word “Securities”: “provided that (a) trade account payables and accrued liabilities arising in the ordinary course of the Company’s business, (b) the Company’s 6.25% Series A-1 Junior Subordinated Debentures, 5.75% Series A-2 Junior Subordinated Debentures and 4.875% Series A-3 Junior Subordinated Debentures and (c) any other indebtedness, Guarantee or other obligation that is specifically designated as being subordinate, or not superior, in right of payment to the Debentures, shall not be considered Senior Debt”.

     (iii) For purposes of the Debentures, the provisions of Section 1404 of the Indenture shall only apply in the case where (A) there has been an event of default with respect to Senior Debt within the meaning of clause (i) of the definition of Senior Debt, (B) the principal amount of such Senior Debt has been accelerated, (C) the outstanding principal amount of Senior Debt at the time of acceleration is at least $100,000,000 and (D) the event of default or acceleration has not been cured, waived, or otherwise ceased to exist. In no other case and to no other Senior Debt shall Section 1404 apply.

     (iv) The Debentures shall rank pari passu with the Company’s 6.25% Series A-1 Junior Subordinated Debentures, 5.75% Series A-2 Junior Subordinated Debentures and 4.875% Series A-3 Junior Subordinated Debentures (the “Outstanding Parity Securities”).

     (w) Registrar, Paying Agent, Authenticating Agent and Place of Payment. The Company hereby appoints the Bank of New York as Security Registrar, Authenticating Agent and Paying Agent with respect to the Debentures. The Debentures may be surrendered for registration of transfer and for exchange at the office or agency of the Company maintained for such purpose in the City of New York, New York and at any other office or agency maintained by the Company for such purpose. The Place of Payment for the Debentures shall be the Paying Agent’s office in New York, New York.

     (x) Defeasance. Until the Scheduled Maturity Date, the Debentures will be subject to Sections 1302 and 1303 of the Indenture.

ARTICLE THREE

REPAYMENT OF THE DEBENTURES

     3.1. Repayment

     The Company shall, not more than 30 nor less than 10 Business Days prior to each Repayment Date (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of the principal amount of Debentures to be repaid on such date pursuant to Section 2.1(d).

3.2. Selection of Securities to be Repaid

     If less than all the Debentures are to be repaid on any Repayment Date, the particular Debentures to be repaid shall be selected not more than 30 days prior to such Repayment Date by the Trustee, from the Outstanding Debentures not previously repaid or redeemed or as to which notice of repayment or redemption has been given, by such other method as the Trustee may deem fair and appropriate and which may provide for the selection for repayment of a portion of the principal amount of any Debenture, provided that the portion of the principal amount of any Debenture not repaid shall be in an authorized denomination (which shall not be less than the minimum authorized denomination).

     The Trustee shall promptly notify the Company in writing of the Debentures selected for partial repayment and the principal amount thereof to be repaid. For all purposes hereof, unless the context otherwise requires, all provisions relating to the repayment of Debentures shall relate, in the case of any Debenture repaid or to be repaid only in part, to the portion of the principal amount of such Debenture which has been or is to be repaid.

3.3. Notice of Repayment

     Notice of repayment shall be given by first-class mail, postage prepaid, mailed at least 10 calendar days, but no more than 15 calendar days, prior to the Repayment Date, to each Holder of Debentures to be repaid, at the address of such Holder as it appears in the Security Register.

     Each notice of repayment shall identify the Debentures to be repaid (including CUSIP number, if a CUSIP number has been assigned to the Debentures) and shall state:

     (a) the Repayment Date;

     (b) if less than all Outstanding Debentures are to be repaid, the identification (and, in the case of partial repayment, the respective principal amounts) of the particular Debentures to be repaid;

     (c) that on the Repayment Date, the principal amount of the Debentures or portions thereof to be repaid will become due and payable, and that interest thereon, if any, shall cease to accrue on and after said date;

     (d) whether any deferred interest shall remain outstanding on any Debentures to be repaid, and if so, the amount of such deferred interest and that compound interest thereon shall continued to accrue on and after said date until paid; and

     (e) the place or places where such Debentures are to be surrendered for payment of the principal amount thereof.

AMERICAN INTERNATIONAL GROUP, INC.

No.		CUSIP No.:

     American International Group, Inc., a corporation duly organized and existing under the laws of Delaware (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of l Dollars ($l) on June 15, 2077, or if such day is not a Business Day, the following Business Day (the “Final Maturity Date”); provided that the principal amount of, and all accrued and unpaid interest on, this Security shall be payable in full on June 15, 2047, or if such day is not a Business Day, the next Business Day (the “Scheduled Maturity Date”), or any subsequent Interest Payment Date (as hereinafter defined) to the extent set forth in the Indenture hereinafter referred to. As provided in the Indenture, the principal of this Security is payable on the Scheduled Maturity Date only to the extent the Company has raised sufficient Eligible Repayment Proceeds. The Company’s obligation to raise Eligible Repayment Proceeds is subject to certain limitations and restrictions described in the Fourth Supplemental Indenture hereinafter referred to. In connection with the issuances of this Security, the Company has entered into a Replacement Capital Covenant that contains restrictions on the Company’s ability to repay the principal of this Security.

     This Security shall bear interest (i) from and including l, 20 l to, but excluding the Scheduled Maturity Date, payable (subject to deferral as set forth herein and in the Indenture) at the rate of 6.45% per annum quarterly in arrears on March 15, June 15, September 15 and December 15 in each year, commencing l, 20 l (computed on the basis of a 360-day year comprised of twelve 30-day months), and (ii) from and including the Scheduled Maturity Date, at an annual rate equal to Three-month LIBOR (as defined in the Indenture) plus 1.82% (computed on the basis of a 360-day year and the actual number of days elapsed), payable (subject to deferral as set forth herein and in the Indenture) quarterly in arrears on March 15, June 15, September 15 and December 15 in each year, commencing September 15, 2047, until the principal hereof is paid or made available for payment (each such date referred to in clause (i) or (ii), an “Interest Payment Date”). In the event that any Interest Payment Date on or before the Scheduled Maturity Date would otherwise fall on a day that is not a Business Day, the interest payment due on that date shall be postponed to the next day that is a Business Day and no interest shall accrue as a result of that postponement. In the event that any Interest Payment Date after the Scheduled Maturity Date would otherwise fall on a day that is not a Business Day, that Interest Payment Date shall be postponed to the next day that is a Business Day; however, if the postponement would cause the day to fall in the next calendar month, the Interest Payment Date will instead be brought forward to the immediately preceding Business Day. Any installment of interest (or portion thereof) deferred in accordance with the Indenture or otherwise unpaid on the relevant Interest Payment Date shall bear interest, to the extent permitted by law, at the rate of interest then in effect on this Security, from the relevant Interest Payment Date, compounded on each subsequent Interest Payment Date, until paid in accordance with the Indenture.

     A “Business Day” shall mean any day other than (i) a Saturday, Sunday or other day on which banking institutions in The City of New York are authorized or required by law or executive order to remain closed and (ii) on or after the Scheduled Maturity Date, a day which is not a London Banking Day.

     The interest (other than deferred interest) so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered (i) at the close of business on the Business Day next preceding the Interest Payment Date if this Security is issued in the form of a Global Security, or (ii) the close of business on the fifteenth day (whether or not a Business Day) next preceding such Interest Payment Date if this Security is not issued in the form of a Global Security. Any such interest not so punctually paid or duly provided for (other than deferred interest) will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

Any deferred interest shall be payable to the holder of record of this Security as provided below.

     The Company shall have the right, at any time and from time to time, prior to the Final Maturity Date to defer the payment of interest on this Security for one or more consecutive Interest Periods that do not exceed 40 consecutive Interest Periods; provided that no Deferral Period shall extend beyond the Final Maturity Date or the earlier redemption of the Securities of this series. As provided in the Indenture, the payment of deferred interest is subject to the Company’s ability to raise Eligible APM Proceeds. The Company’s obligation to raise Eligible APM Proceeds is subject to certain limitations, restrictions and exceptions described in the Fourth Supplemental Indenture.

     At the end of any Deferral Period, the Company shall pay all deferred interest on this Security (together with compounded interest thereon, if any, to the extent permitted by applicable law), to the Person in whose name this Security is registered at the close of business on the Business Day next preceding the Interest Payment Date at the end of such Deferral Period or, in the event this Security ceases to be held in the form of a Global Security, at the close of business on the date 15 days prior to the end of the Deferral Period, whether or not a Business Day. Upon termination of any Deferral Period and upon the payment of all deferred interest and any compounded interest then due on any Interest Payment Date, the Company may elect to begin a new Deferral Period, subject to the above requirements and those in the Indenture. The Company may elect to pay deferred interest on any Interest Payment Date during any Deferral Period to the extent permitted, and shall pay deferred interest (including compounded interest thereon) to the extent required, by the Indenture.

     To the extent permitted by law, each Holder of this Security, by such Holder’s acceptance of this Security agrees that if a Bankruptcy Event shall occur prior to the redemption or repayment of this Security, such Holder shall only have a claim for deferred and unpaid interest (including compounded interest thereon) to the extent such interest (including compounded interest thereon) relates to the earliest two years of the portion of the Deferral Period for which interest has not so been paid.

     The Company shall give written notice to the Trustee and the Holders of this Security of its election to begin any Deferral Period at least one Business Day prior to the Regular Record Date for that Interest Payment Date, provided, however, that the Company’s failure to pay any interest due within five Business Days after any Interest Payment Date shall automatically and without any further action by any Person be deemed to commence a Deferral Period.

     Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

     Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

REVERSE OF SECURITY

     This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under a Junior Subordinated Debt Indenture, dated as of March 13, 2007 (herein called the “Base Indenture”), which term shall have the meaning assigned to it in such instrument, as supplemented by a Fourth Supplemental Indenture, dated as of June 7, 2007 (herein called the “Fourth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), in each case, between the Company and The Bank of New York, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Debt and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof limited in aggregate principal amount to $750,000,000 (except for Securities authenticated and delivered upon registration or transfer of, or exchange for, or in lieu of, other Securities pursuant to Section 304, 305, 306, 906, or 1107 of the Base Indenture or Section 3.5 of the Fourth Supplemental Indenture); provided, that the Company may authenticate and deliver up to an additional $112,500,000 principal amount of Debentures pursuant to the exercise of the underwriters’ over-allotment option under the Underwriting Agreement, dated as of May 31, 2007, between the Company and Citigroup Global Markets Inc., Merrill, Lynch, Pierce, Fenner & Smith Incorporated , Morgan Stanley & Co. Incorporated, UBS Securities LLC and Wachovia Capital Markets, LLC, as representatives of the several underwriters; provided, further, that the Company may from time to time authenticate and deliver under the Indenture and the Fourth Supplemental Indenture additional Securities (any such additional Securities, the “Additional Securities”) in addition to the $750,000,000 principal amount previously provided for and in addition to the principal amount of any Securities delivered pursuant to the exercise of the underwriters’ over-allotment option, so long as the aggregate principal amount of Securities delivered under the Indenture and the Fourth Supplemental Indenture does not exceed $1,237,500,000, which Additional Securities may accrue interest from a different date than this Security, as may be specified pursuant to Section 301 of the Base Indenture, so long as the company reasonably determines that the Additional Securities so authenticated and delivered will be fungible for United States federal income tax purposes.

     All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

     The Securities of this series are subject to redemption upon not less than 10 days nor more than 60 days’ prior notice by first class mail, postage pre-paid, to each Holder of Securities to be redeemed, (i) on any Interest Payment Date on or after June 15, 2012, in whole or in part, at the option of the Company, at 100% of the principal amount thereof, (ii) prior to June 15, 2012, in whole but not in part upon the occurrence of a Tax Event, at 100% of the principal amount thereof or (iii) prior to June 15, 2012, in whole

but not in part upon the occurrence of a Rating Agency Event at (A) 100% of the principal amount thereof or (B) the Make-Whole Redemption Price, if greater, in any such case, plus accrued and unpaid interest to the Redemption Date.

     In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

     The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee as his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Debt, whether now outstanding or hereafter created, incurred, assumed or Guaranteed, and waives reliance by each such holder of Senior Debt upon said provisions.

     The Indenture contains provisions for defeasance of the entire indebtedness of this Security at any time prior to the Scheduled Maturity Date upon compliance with certain conditions set forth in the Indenture.

     The Securities of this series are entitled to the benefits of the Events of Default described in Section 2.1(j) of the Fourth Supplemental Indenture and the Enforcement Events as defined in the Fourth Supplemental Indenture. The Holder of this Security and the Trustee shall be entitled to the remedies provided by Section 502 of the Base Indenture only if an Event of Default specified in clause (1) of Section 2.1(j) of the Fourth Supplemental Indenture shall occur with respect to the Securities of this series. If an Event of Default specified in Section 501(5) or Section 501(6) of the Base Indenture shall occur with respect to the Securities of this series, then in every such case the principal amount of all the Securities of this series shall become automatically due and payable immediately, without any declaration or other action on the part of the Trustee or any Holder. An Event of Default specified in clause (2) of Section 2.1(j) of the Fourth Supplemental Indenture shall not entitle the Holders to the benefits of Section 502 of the Base Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified

percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default or Enforcement Event with respect to the Securities of this series, the Holders of not less than 25% (or, in the case of an Enforcement Event, a majority) in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default or Enforcement Event, as the case may be, as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates to the extent provided by Section 2.1(n) of the Fourth Supplemental Indenture.

     As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without coupons in denominations of $25.00 and integral multiples of $25.00 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     The Company and, by its acceptance of this Security or a beneficial interest therein, the Holder of, and any Person that acquires beneficial interest in, this Security agree that, for United States federal, state and local tax purposes, it is intended that this Security constitute indebtedness.

     THE BASE INDENTURE, THE FOURTH SUPPLEMENTAL INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
