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 its registered assigns,
the principal sum of [ ] dollars on October 1, [INCLUDE IF NOTE IS 5-YEAR NOTE -
2010] [INCLUDE IF NOTE IS 10-YEAR NOTE - 2015], and to pay interest thereon from
September 30, 2005, or from the most recent Interest Payment Date (as defined
below) to which interest has been paid or duly provided for, semiannually in
arrears on April 1 and October 1 in each year (each such date, an "Interest
Payment Date"), commencing on April 1, 2006 at the rate of [INCLUDE IF NOTE IS
5-YEAR NOTE - 4.700%] [INCLUDE IF NOTE IS 10-YEAR NOTE - 5.050%] per annum,
until the principal hereof is paid or made available for payment. The interest
so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in such Indenture, be paid to the Person in whose name
this Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest, which shall be the March
15 or September 15 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for 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 Note
(or one or more Predecessor Notes) 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 which shall be given to Holders of Notes 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 Notes may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in said
Indenture.

     Interest shall be computed on the basis of a 360-day year comprised of
twelve 30-day months.

     In the event that an Interest Payment Date is not a Business Day, the
Company shall pay interest on the next day that is a Business Day, with the same
force and effect as if made on the Interest Payment Date, and without any
interest or other payment with respect to the delay. If the Stated Maturity or
earlier Redemption Date falls on a day that is not a Business Day, the payment
of principal, premium, if any, and interest, if any, need not be made on such
date, but may be made on the next succeeding Business Day, with the same force
and effect as if made on the Stated Maturity or earlier Redemption Date,
provided that no interest shall accrue for the period from and after such Stated
Maturity or earlier Redemption Date.

     [INCLUDE IF NOTE IS ORIGINAL NOTE - Pursuant to the Exchange and
Registration Rights Agreement, dated as of September 30, 2005 (the "Registration
Rights Agreement"), by and among the Company and the Initial Purchasers (as
defined therein), the Company has agreed for the benefit of the Holders from
time to time of the Notes that it will (i) file under the Securities Act, no
later than 300 days after the date on which the Notes are initially issued (the
"Issue Date"), a registration statement (the "Exchange Offer Registration
Statement") registering debt securities substantially identical to the Notes
(except that such securities will not contain terms with respect to the Special
Interest payments described below or transfer restrictions) pursuant to an
exchange offer (the "Exchange Offer"), (ii) use its commercially reasonable
efforts to cause the Exchange Offer Registration Statement to become effective
under the Securities Act no later than 360 days following the Issue Date and
(iii) use its commercially reasonable efforts to cause the Exchange Offer to
remain open at least 20 business days and to commence and complete the Exchange
Offer no later than 30 days after the Exchange Offer Registration Statement has
become effective; provided, however, that if on or prior to the time the
Exchange Offer is completed, existing Commission (as defined in the Indenture)
interpretations are changed such that this Note is not or would not be, upon
receipt under the Exchange Offer, transferable by the Holder of this Note
without restriction under the Securities Act, the Company has agreed to file
under the Securities Act no later than 390 days after the Issue Date, a "shelf"
registration statement providing for the registration of and the sale on a
continuous or delayed basis by the Holder of this Note (such registration
statement, the "Shelf Registration Statement") and to use its commercially
reasonable efforts to cause the Shelf Registration Statement to become effective
no later than 90 days after the Shelf Registration Statement is filed.

     In the event that (i) the Exchange Offer has not been completed within 390
days after the Issue Date, (ii) a Shelf Registration Statement is required to be
filed and is not effective within 480 days of the Issue Date, or (iii) the
Exchange Offer Registration Statement or, if applicable, the Shelf Registration
Statement is filed and declared effective but shall thereafter either be
withdrawn by the Company or shall become subject to an effective stop order
issued pursuant to Section 8(d) of the Securities Act suspending the
effectiveness of such registration statement (except as specifically permitted
in the Registration Rights Agreement) without being succeeded by a
post-effective amendment or a prospectus supplement to such registration
statement or an additional registration statement that cures such failure and
that is itself declared effective


                                      -9-

promptly, in each case (i) through (iii) upon the terms and conditions set forth
in the Registration Rights Agreement (each such event referred to in clauses (i)
through (iii), a "Registration Default" and each period during which a
Registration Default has occurred and is continuing, until the earlier of such
time as no Registration Default is in effect or the first date the Notes become
eligible to be sold pursuant to paragraph (k) of Rule 144 under the Securities
Act of 1933, a "Registration Default Period"), then interest will accrue (in
addition to any stated interest on this Note) at a per annum rate of 0.125% for
the first 90 days of the Registration Default Period and at a per annum rate of
0.25% thereafter for the remaining portion of the Registration Default Period;
provided that the Company shall not be required to pay Special Interest for more
than one Registration Default at any given time and in no event shall Special
Interest accrue at a rate in excess of 0.25% per annum. Interest accruing as a
result of a Registration Default is referred to herein as "Special Interest." In
the case of a Registration Default, the Company's only obligation under the
Registration Rights Agreement is to pay Special Interest. Accrued Special
Interest, if any, shall be paid in cash in arrears on each Interest Payment Date
for the Notes; and the amount of accrued Special Interest shall be determined on
the basis of the number of days actually elapsed.]

     Payment of the principal of and interest on this Note 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.

     Reference is hereby made to the further provisions of this Note 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 Note 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.

     "Comparable Treasury Issue" means the U.S. Treasury security selected by
the Quotation Agent as having a maturity comparable to the remaining term of the

of such Notes.

     "Comparable Treasury Price" means, with respect to any Redemption Date, the
average of the Reference Treasury Dealer Quotations for such Redemption Date.

Primary Treasury Dealer selected by the Quotation Agent after consultation with

the third business day preceding such Redemption Date.

     In the event of redemption of this Note in part only, a new Note or Notes

     As set forth in, and subject to, the provisions of the Indenture, no Holder
of this Note will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder, unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default, the
Holders of not less than 25% in principal amount of the Outstanding Notes shall
have made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in principal amount of the Outstanding Notes a

proceeding within 60 days; provided, however, that such limitations do not apply
to a suit instituted by the Holder hereof for the enforcement of payment of the
principal of (and premium, if any) or any interest of this Note on or after the
respective due date expressed herein.

     If an Event of Default with respect to Notes of this series shall occur and
be continuing, the principal of the Notes of this series may be declared due and
payable in the manner and with the effect provided in the Indenture.

the Indenture) and the Exchange Notes (as defined in the Indenture) shall
constitute one series for all purposes under the Indenture, including without
limitation, amendments, waivers and redemptions.

SECTION 2.6 TRANSFER AND EXCHANGES; SECURITIES ACT LEGENDS

     (a) Certain Transfers and Exchanges. Transfers and exchanges of Notes and
beneficial interests in a Global Note of the kinds specified in this Section
2.6(a) shall be made only in accordance with this Section 2.6(a).

          (i) Non-Global Note to Non-Global Note. A Note that is not a Global
     Note may be transferred, in whole or in part, to a Person who takes
     delivery in the form of another Note that is not a Global Note as provided
     in Section 305 of the Existing Indenture, provided that, if the Note to be
     transferred in whole or in part is a Restricted Note, or is a Regulation S
     Note and the transfer is to occur during the Restricted Period, then the
     Trustee shall have received (i) a Restricted Notes Certificate,
     satisfactory to the Company and duly executed by the transferor Holder or
     his attorney duly authorized in writing, in which case the transferee
     Holder shall take delivery in the form of a Restricted Note or (ii) a
     Regulation S Certificate, satisfactory to the Company and duly executed by
     the transferor Holder or his attorney duly authorized in writing, in which
     case the transferee Holder shall take delivery in the form of a Regulation
     S Note.

          (ii) Restricted Global Note to Regulation S Global Note. If the owner
     of a beneficial interest in the Restricted Global Note wishes at any time
     to transfer such interest to a Person who wishes to acquire the same in the
     form of a beneficial interest in the Regulation S Global Note of the same
     series, such transfer may be effected only in accordance with the
     provisions of this Section 2.6(a)(ii) and Section 2.6(a)(iv) below and
     subject to the Applicable Procedures. Upon receipt by the Trustee, as
     Security Registrar, of (i) an order given by the


                                      -15-

<PAGE>

     Depositary or its authorized representative directing that a beneficial
     interest in the Regulation S Global Note in a specified principal amount be
     credited to a specified Agent Member's account and that a beneficial
     interest in the Restricted Global Note in an equal amount be debited from
     another specified Agent Member's account and (ii) a Regulation S
     Certificate, satisfactory to the Company and duly executed by the Holder of
     such Restricted Global Note or his attorney duly authorized in writing,
     then the Trustee, as Security Registrar but subject to Section 2.6(a)(iv)
     below, shall reduce the principal amount of such Restricted Global Note and
     increase the principal amount of such Regulation S Global Note by such
     specified principal amount.

          (iii) Regulation S Global Note to Restricted Global Note. If the owner
     of a beneficial interest in the Regulation S Global Note wishes at any time
     to transfer such interest to a Person who wishes to acquire the same in the
     form of a beneficial interest in the Restricted Global Note of the same
     series, such transfer may be effected only in accordance with this Section
     2.6(a)(iii) and subject to the Applicable Procedures. Upon receipt by the
     Trustee, as Security Registrar, of (i) an order given by the Depositary or
     its authorized representative directing that a beneficial interest in the
     Restricted Global Note in a specified principal amount be credited to a
     specified Agent Member's account and that a beneficial interest in the
     Regulation S Global Note in an equal principal amount be debited from
     another specified Agent Member's account and (ii) if such transfer is to
     occur during the Restricted Period, a Restricted Notes Certificate,
     satisfactory to the Company and duly executed by the Holder of such
     Regulation S Global Note or his attorney duly authorized in writing, then
     the Trustee, as Security Registrar, shall reduce the principal amount of
     such Regulation S Global Note and increase the principal amount of such
     Restricted Global Note by such specified principal amount. If transfers
     under this Section 2.6(a)(iii) occur after the Restricted Period, no
     Restricted Notes Certificate will be required and the beneficial interest
     in the Regulation S Global Note so transferred shall be credited to an
     Agent Member's account in a Global Note that does not bear a Securities Act
     Legend.

          (iv) Regulation S Global Note to be Held Through Euroclear or
     Clearstream during Restricted Period. The Company shall use its best
     efforts to cause the Depositary to ensure that, until the expiration of the
     Restricted Period, beneficial interests in the Regulation S Global Note may
     be held only in or through accounts maintained at the Depositary by
     Euroclear and Clearstream (or by Agent Members acting for the account
     thereof), and no person shall be entitled to effect any transfer or
     exchange that would result in any such interest being held otherwise than
     in or through such an account; provided that this Section 2.6(a)(iv) shall
     not prohibit any transfer or exchange of such an interest in accordance
     with Section 2.6(a)(iii) above.


                                      -16-

     (b) Securities Act Legends. Rule 144A Notes and their Successor Notes shall
bear the Restricted Notes Legend and Regulation S Notes and their Successor
Notes shall bear the Regulation S Legend, subject to the following:

          (i) subject to the following Clauses of this Section 2.6(b), a Note or
     any portion thereof which is exchanged, upon transfer or otherwise, for a
     Global Note or any portion thereof shall bear the Securities Act Legend
     borne by such Global Note while represented thereby;

          (ii) subject to the following Clauses of this Section 2.6(b), a new
     Note which is not a Global Note and is issued in exchange for another Note
     (including a Global Note) or any portion thereof, upon transfer or
     otherwise, shall bear the Securities Act Legend borne by such other Note,
     provided that, if such new Note is required pursuant to Section 2.6(a) to
     be issued in the form of a Restricted Note, it shall bear the Restricted
     Notes Legend and, if such new Note is so required to be issued in the form
     of a Regulation S Note, it shall bear the Regulation S Legend;

          (iii) at any time when a Note has been transferred in a manner, or a
     sufficient amount of time has elapsed, so that a Note may be transferred
     without registration or limitation under the Securities Act, a new Note
     which does not bear a Securities Act Legend may be issued in exchange for
     or in lieu of a Note which bears such a legend if the Trustee has received
     an Unrestricted Notes Certificate, satisfactory to the Company and duly
     executed by the Holder of such legended Note or his attorney duly
     authorized in writing, and after such date and receipt of such certificate,
     the Trustee shall authenticate and deliver such a new Note in the manner
     provided for in the Existing Indenture.

          (iv) a new Note which does not bear a Securities Act Legend may be
     issued in exchange for or in lieu of a Note (other than a Global Note) or
     any portion thereof which bears such a legend if, in the judgment of the
     Company, placing such a legend upon such new Note is not necessary to
     ensure compliance with the registration requirements of the Securities Act,
     and the Trustee, at the direction of the Company, shall authenticate and
     deliver such a new Note as provided in this Article Two; and

          (v) notwithstanding the foregoing provisions of this Section 2.6(b), a
     Successor Note of a Note that does not bear a particular form of Securities
     Act Legend shall not bear such form of legend unless the Company has
     reasonable cause to believe that such Successor Note is a "restricted
     security" within the meaning of Rule 144, in which case the Trustee, at the
     direction of the Company, shall authenticate and deliver a new Note bearing
     the Restricted Notes Legend in exchange for such Successor Note as provided
     in this Article Two.

     This certificate relates to U.S. $_____________ principal amount of Notes,

     CUSIP No(s). ______________________

     ISIN ______________________________

     COMMON CODE _______________________

     CERTIFICATE No(s). ________________

     The person in whose name this certificate is executed below (the
"Undersigned") hereby certifies that (i) it is the sole beneficial owner of the
Specified Securities, (ii) it is acting on behalf of all the beneficial owners
of the Specified Securities and is duly authorized by them to do so or (iii) it
is the Holder of a Global Note and has received a certification to the effect
set forth below. Such beneficial owner or owners are referred to herein

     The Owner has requested that the Specified Securities be transferred to a
person (the "Transferee") who will take delivery in the form of a Restricted

such transfer is being effected pursuant to an effective registration statement
under the Securities Act, it is being effected in accordance with Rule 144A or

jurisdictions. Accordingly, the Owner hereby further certifies as follows:

          (1) Rule 144A Transfers. If the transfer is being effected in
     accordance with Rule 144A:

               (A) the Specified Securities are being transferred to a person
          that the Owner and any person acting on its behalf reasonably believe
          is a "qualified institutional buyer" within the meaning of Rule 144A,
          acquiring for its own account or for the account of a qualified
          institutional buyer; and

               (B) the Owner and any person acting on its behalf have taken
          reasonable steps to ensure that the Transferee is aware that the Owner
          may be relying on Rule 144A in connection with the transfer; and

          (2) Rule 144 Transfers. If the transfer is being effected pursuant to
     Rule 144:

          the transfer is occurring after a holding period of at least one year
          (computed in accordance with paragraph (d) of Rule 144) has elapsed
          since the Specified Securities were last acquired from the Company or
          from an affiliate of the Company, whichever is later, and is being
          effected in accordance with the applicable amount, manner of sale and
          notice requirements of Rule 144.

     This certificate and the statements contained herein are made for your
benefit and the benefit of the Company.

Specified Securities, (ii) it is acting on behalf of all the beneficial owners
of the Specified Securities and is duly authorized by them to do so or (iii) it
is the Holder of a Global Note and has received a certification to the effect

states of the United States and other jurisdictions. Accordingly, the Owner
hereby further certifies or has certified as follows:

          (1) Rule 904 Transfers. If the transfer is being effected in
     accordance with Rule 904 of Regulation S:

               (A) the Owner is not a Distributor of the Notes, an affiliate of
          the Company or any such Distributor or a person acting on behalf of
          any of the foregoing;

               (B) the offer of the Specified Securities was not made to a
          person in the United States or for the account or benefit of a U.S.
          Person;

               (C) either:

                    (i) at the time the buy order was originated, the Transferee
               was outside the United States or the Owner and any person acting
               on its behalf reasonably believed that the Transferee was outside
               the United States, or

                    (ii) the transaction is being executed in, on or through the
               facilities of the Eurobond market, as regulated by the
               International Securities Market Association or another designated
               offshore securities market and neither the Owner nor any person
               acting on its behalf knows that the transaction has been
               prearranged with a buyer in the United States;

               (D) no directed selling efforts have been made in the United
          States by or on behalf of the Owner or any affiliate thereof;

               (E) if the Owner is a dealer in securities or has received a
          selling concession, fee or other remuneration in respect of the
          Specified Securities, and the transfer is to occur during the
          Restricted Period, then the requirements of Rule 904(b)(1) have been
          satisfied; and

               (F) the transaction is not part of a plan or scheme to evade the
          registration requirements of the Securities Act.

          (2) Rule 144 Transfers. If the transfer is being effected pursuant to
     Rule 144:

          the transfer is occurring after a holding period of at least one year
          (computed in accordance with paragraph (d) of Rule 144) has elapsed
          since the Specified Securities were last acquired from the Company or
          from an affiliate of the
