If the Calculation Agent determines there is an industry-accepted substitute or successor reference rate, then the Calculation Agent may, in its sole discretion, also determine what business day convention to use, the definition of business day, the reference rate determination date to be used and any other relevant methodology for calculating such substitute or successor reference rate, including any adjustment factor needed to make such substitute or successor reference rate comparable to the Three-month LIBOR in a manner that is consistent with industry-accepted practices for such substitute or successor reference rate. The establishment of the Three-month LIBOR for each Floating-Rate Interest Period by the Calculation Agent shall (in the absence of manifest error) be final and binding.

“Validus” has the meaning set forth in Section 2.1(m).

(a) Designation. The Debentures shall be known and designated as the “5.750% Fixed-to-Floating Rate Series A-9 Junior Subordinated Debentures Due 2048”. The CUSIP number for the Debentures is 026874 DM6.

(b) Aggregate Principal Amount. The maximum aggregate principal amount of the Debentures that may be authenticated and delivered under this Fifteenth Supplemental Indenture is initially limited to $750,000,000 (except for Debentures authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Debentures pursuant to Section 304, 305, 306, 906 or 1107 of the Base Indenture). The Company may, without the consent of the Holders of the Debentures, issue additional debentures of this series in an unlimited amount having the same ranking,

-7-

interest rate, Stated Maturity, CUSIP number and terms as to status, redemption or otherwise as the Debentures (other than dates as to issuance and the initial accrual of interest), in which event such debentures and the Debentures shall constitute one series for all purposes under the Indenture, including without limitation, amendments, waivers and redemptions.

(c) Form and Denominations. The Debentures will be issued only in fully registered form, and the authorized denominations of the Debentures shall be $2,000 principal amount and integral multiples of $1,000 in excess thereof. The Debentures will initially be issued in the form of one or more Global Securities substantially in the form of Annex A (attached hereto), with such modifications thereto as may be approved by the authorized officer executing the same. The Debentures will be denominated in U.S. dollars and payments of principal and interest will be made in U.S. dollars.

Upon their original issuance, the Debentures shall be issued in the form of Global Securities registered in the name of the Depositary or its nominee and deposited with the Trustee, as custodian for the Depositary, for credit by the Depositary to the respective accounts of beneficial owners of the Debentures represented thereby (or such other accounts as they may direct). Each such Global Security will constitute a single Security for all purposes of the Indenture.

(d) Stated Maturity. The principal amount of, and all accrued and unpaid interest (including compounded interest) on, the Outstanding Debentures shall be payable in full on April 1, 2048, or if such day is not a Business Day, the next Business Day (the “Stated Maturity”).

(e) Rate of Interest. The Debentures shall bear interest on their principal amount (i) from and including March 26, 2018 to but excluding April 1, 2028 at the rate of 5.750% per annum, computed on the basis of a 360-day year comprised of twelve 30-day months, and (ii) thereafter at an annual rate equal to the Three-month LIBOR plus 2.868%, computed on the basis of a 360-day year and the actual number of days elapsed. All percentages resulting from any calculation of the Three-month LIBOR will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. All amounts used in or resulting from any calculation will be rounded upward or downward as appropriate, to the nearest cent with one-half cent or more being rounded upward. Subject to Section 2.1(g): in the case of Section 2.1(e)(i), interest on the Debentures shall be payable semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2018 and ending on April 1, 2028 (each such date, a “Fixed-Rate Interest Payment Date”) and in the case of Section 2.1(e)(ii), interest on the Debentures shall be payable quarterly in arrears on April 1, July 1, October 1 and January 1 of each year, beginning on July 1, 2028 (each such date, a “Floating-Rate Interest Payment Date”). In the event any Fixed-Rate Interest Payment 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 Floating-Rate Interest Payment Date would otherwise fall

-8-

on a day that is not a Business Day, such Floating-Rate Interest Payment Date will be postponed to the following Business Day and interest will accrue to the actual Floating-Rate Interest Payment Date, 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.

(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 to defer the payment of interest on the Debentures for one or more consecutive Interest Periods that do not exceed 5 years; provided that no Deferral Period shall extend beyond the Stated Maturity or the earlier redemption of the Debentures. If 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 to, subject to the exceptions specified in clause (vi) of this Section 2.1(g): (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares of 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. For the avoidance of doubt, the Company shall calculate any such deferred interest.

-9-

(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.

(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) The restrictions in clauses (i) 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 (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 such pari passu securities and the Debentures 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, or (g) any repayment or redemption of a security necessary to avoid a breach of the instrument governing that security.

There is no default for failure to pay interest if the Company has properly commenced or is continuing a Deferral Period.

(i) Acceleration of Maturity. If an Event of Default specified in Section 501(5) or 501(6) of the Base 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. There is no right of acceleration except upon the occurrence of an Event of Default as described in clause (i) of Section 2.1(h)

(j) 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 Base Indenture.

(l) Waiver of Past Defaults. Notwithstanding anything to the contrary in Section 513 of the Base 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 Base Indenture cannot be waived, with respect to the Debentures and its consequences, without the consent of each Holder of the Debentures.

(m) Special Mandatory Redemption. If the Company’s acquisition of Validus Holdings, Ltd. (“Validus”) is not consummated on or prior to September 21, 2018 (or such later date as extended by agreement under the Agreement and Plan of Merger, the “Walk-Away Date”) or, if prior to such date, the Agreement and Plan of Merger for such acquisition is terminated (each, a “Special Mandatory Redemption Event”), the provisions set forth below will be applicable:

AMERICAN INTERNATIONAL GROUP, INC.

5.750% FIXED-TO-FLOATING RATE SERIES A-9 JUNIOR SUBORDINATED

DEBENTURES DUE 2048

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 [•] Dollars ($[•]) on April 1, 2048 (or, if this day is not a Business Day, the following Business Day) (the “Stated Maturity”).

This Security shall bear interest (i) from and including March 26, 2018 to but excluding April 1, 2028, payable (subject to deferral as set forth herein and in the Indenture) at the rate of 5.750% per annum semi-annually in arrears on April 1 and October 1 in each year, beginning on October 1, 2018 and ending on April 1, 2028 (computed on the basis of a 360-day year comprised of twelve 30-day months), and (ii) from and including April 1, 2028, at an annual rate equal to the Three-month LIBOR (as defined in the Indenture) plus 2.868% (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 April 1, July 1, October 1 and January 1 in each year, beginning on July 1, 2028, until the principal hereof is paid or made available for payment (each such date referred to in clause (i), a “Fixed-Rate Interest Payment Date”, and each such date referred to in clause (ii), a “Floating-Rate Interest Payment Date”). In the event that any Fixed-Rate Interest Payment Date falls 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 Floating-Rate Interest Payment Date would otherwise fall on a day that is not a Business Day, that Floating-Rate Interest Payment Date shall be postponed to the next day that is a Business Day and interest will accrue to the actual Floating-Rate Interest Payment Date, 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 the Indenture or otherwise unpaid on the relevant Fixed-Rate Interest Payment Date or Floating-Rate Interest Payment Date, as the case may be (the “Interest Payment Date”) shall bear additional 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 each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to close.

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) at the close of business on the day 15 days prior to that Interest Payment Date (whether or not a Business Day), 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 Stated Maturity to defer the payment of interest on this Security for one or more consecutive Interest Periods that do not exceed 5 years; provided that no Deferral Period shall extend beyond the Stated Maturity or the earlier redemption of the Securities of this series.

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.

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 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.

This Security is one of the series designated on the face hereof limited in aggregate principal amount to $750,000,000 (except for Debentures authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Debentures pursuant to Section 304, 305, 306, 906, or 1107 of the Base Indenture).

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

If the Company’s acquisition of Validus Holdings, Ltd. (“Validus”) is not consummated on or prior to September 21, 2018 (or such later date as extended by agreement under the Agreement and Plan of Merger, the “Walk-Away Date”) or, if prior to such date, the Agreement and Plan of Merger for such acquisition is terminated (each, a “Special Mandatory Redemption Event”), the provisions set forth below will be applicable:

Upon the occurrence of a Special Mandatory Redemption Event, the Debentures will be redeemed in whole at a special mandatory redemption price (the “Special Mandatory Redemption Price”) equal to 101% of the aggregate principal amount of the Debentures, plus accrued and unpaid interest (including compounded interest) on the principal amount of the Debentures to, but not including, the Special Mandatory Redemption Date.

Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than 5 Business Days following such Special Mandatory Redemption Event) notify the Trustee in writing of such event, and will, no later than 5 Business Days following such notice to the Trustee, mail a notice of redemption to the registered address of each Holder of the Debentures (such date of notification to the Holders, the “Redemption Notice Date”), that the Debentures will be redeemed on the 30th day following the Redemption Notice Date (such date, the “Special Mandatory Redemption Date”), in each case in accordance with the applicable provisions of the Indenture. At or prior to 12:00 p.m. (New York City time) on the Business Day

immediately preceding the Special Mandatory Redemption Date, the Company shall deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price for the Debentures to be redeemed. If such deposit is made as provided above, all of the Debentures to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

For purposes of the foregoing Special Mandatory Redemption provisions, the following term is applicable:

“Agreement and Plan of Merger” means the definitive agreement by and among the Company, Validus, and Venus Holdings Limited, a wholly owned subsidiary of the Company, pursuant to which the Company agreed to acquire Validus.

The Debentures shall be redeemable in accordance with Article Eleven of the Base Indenture, provided that the Debentures shall be redeemable at the Company’s option, (1) at any time on or after April 1, 2028, in whole or in part, at 100% of the principal amount thereof, plus accrued and unpaid interest (including compounded interest) thereon to but excluding the Redemption Date and (2) at any time prior to April 1, 2028, in whole, but not in part, within 90 days after the occurrence of a Tax Event, a Rating Agency Event or a Regulatory Capital Event, at a Redemption Price equal to (a) in the case of a Tax Event or Regulatory Capital Event, 100% of the principal amount of the Debentures being redeemed plus accrued and unpaid interest (including compounded interest) to but excluding the Redemption Date or (b) in the case of a Rating Agency Event, 102% of the principal amount of the Debentures being redeemed plus accrued and unpaid interest (including compounded interest) to but excluding the Redemption Date; provided that if the Company exercises its right to redeem the Debentures in part prior to April 1, 2028, the aggregate principal amount thereof outstanding after such redemption must be at least $50,000,000.

In the event of redemption of Debentures in part only, new Debentures of this series and of like tenor and of an authorized denomination 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 Debentures of this series do not have the benefit of any sinking fund obligation and are not subject to the repurchase at the option of the Holders.

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

The Debentures shall not be entitled to the benefits of the Events of Default in clauses (1) through (4) of Section 501 of the Base Indenture. The Debentures shall be entitled to the benefits of the Events of Default in clauses (5) and (6) of Section 501 of the Base Indenture. 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.

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 Debentures 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 Debentures 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 Debentures of each series at the time Outstanding, on behalf of the Holders of all Debentures 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 with respect to the Debentures of this series, the Holders of not less than 25% in principal amount of the Debentures 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 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 Debentures 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(j) of the Fifteenth Supplemental Indenture.

As provided in the Indenture and subject to the transfer restrictions and 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 interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer and any other written certification required by the Indenture, in each case in a 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 Debentures 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 Debentures of this series are issuable only in registered form without coupons in denominations of $2,000.00 and integral multiples of $1,000.00 in excess thereof.

As provided in the Indenture and subject to certain limitations therein set forth, Debentures of this series are exchangeable for a like aggregate principal amount of Debentures 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 of the Company.
