Interest Period and in an amount that, in the Calculation Agent’s judgment, is representative of a
single transaction in that market at that time. 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).

Indenture, the principal of, and all accrued and unpaid interest on, all Outstanding
Debentures shall be due and payable on June 15, 2077, or if such day is not a Business Day,
the following Business Day (the “Final Maturity Date”).

-12-

 

     (iv) Any repayment of principal and current interest on the Debentures pursuant to
this Section 2.1(d) on any date prior to the Final Maturity Date shall not affect the
Company’s obligations under Section 2.1(h) with respect to the payment of deferred interest
on the Debentures. 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. For the purposes of the definition
of “Outstanding” in the Indenture, a Debenture, as to which principal and current
interest has been repaid, redeemed or otherwise satisfied by the Company, shall for all
purposes of the Indenture and this Fourth Supplemental Indenture, other than for purposes
of Article XI of the Indenture and Section 2.1(d) and Article III of this Fourth
Supplemental Indenture, be deemed Outstanding so long as any deferred interest on such
Debenture remains unpaid.

     (v) Until principal and current interest on all Outstanding Debentures are paid in
full, the principal of all Outstanding Debentures is automatically accelerated as provided
in Section 2.1(k) or a declaration of acceleration pursuant to Section 502 of the Indenture
occurs, the Company shall use Commercially Reasonable Efforts, subject to a Market
Disruption Event:

     (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).

-13-

 

     (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

-14-

 

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.

-15-

 

     (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

-16-

 

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

-17-

 

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”)

-18-

 

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

-19-

 

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

-20-

 

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

-21-

 

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

-22-

 

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

     3.1. Repayment

-23-

 

     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;

-24-

 

     (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.

     Notice of repayment shall be given by the Company or, at the Company’s request, by the Trustee
in the name and at the expense of the Company and shall be irrevocable.

     3.4. Deposit of Repayment Amount

     Prior to 10:00 a.m., New York City time, on the Repayment Date specified in the notice of
repayment given as provided in Section 3.3, the Company will deposit with the Trustee or with one
or more Paying Agents (or if the Company is acting as its own Paying Agent, the Company will
segregate and hold in trust as provided in Section 1003 of the Indenture) an amount of money
sufficient to pay the principal amount of, and (except to the extent the payment of such accrued
interest shall be prohibited pursuant to Section 2.1(h)) any accrued interest (including compounded
interest) on, all the Debentures which are to be repaid on that date.

     3.5. Payment of Debentures Subject to Repayment

     If any notice of repayment has been given as provided in Section 3.3, the Debentures or
portion of the Debentures with respect to which such notice has been given shall become due and
payable on the Repayment Date. On presentation and surrender of such Debentures as provided in the
notice of repayment, such Debentures or the specified portions thereof shall be paid by the Company
at their principal amount, together with accrued interest (including any compounded interest) to
the Repayment Date (except to the extent the payment of such accrued interest shall be prohibited
pursuant to Section 2.1(h)); provided that, except in the case of a repayment in full of all
Outstanding Debentures, installments of interest whose Stated Maturity is on or prior to the
Repayment Date will be payable to the Holders of such Debentures, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Regular Record Dates
according to their terms and the provisions of Section 307 of the Indenture and Section 2.1(g)(ii)
of this Fourth Supplemental Indenture.

     Section 1107 of the Indenture shall apply to any Debenture repaid in part pursuant to this
Article III.

     If any Debenture subject to repayment shall not be so repaid upon surrender thereof, the
principal of such Debenture shall, until paid, bear interest from the applicable Repayment Date at
the rate prescribed therefore in the Debenture.

$

     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.

A-1

 

     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.

A-2

 

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.

A-3

 

     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.

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

A-6

 

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

A-7

 

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.

A-8

 

     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.

specified or determined as contemplated by Section 301, (C) the principal amount of a Security
denominated in one or more foreign currencies or currency units which shall be deemed to be
Outstanding shall be the U.S. dollar equivalent, determined as of such date in the manner provided
as contemplated by Section 301, of the principal amount of such Security (or, in the case of a

Clause), and (D) Securities owned by the Company, the Guarantor or any other obligor upon the
Securities or any Affiliate of the Company, the Guarantor or of such other obligor shall be
disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall
be protected in relying upon any such request, demand, authorization, direction, notice, consent,
waiver or other action, only Securities which the Trustee knows to be so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to
act with respect to such Securities and that the pledgee is not the Company, the Guarantor or any
other obligor upon the Securities or any Affiliate of the Company, the Guarantor or of such other
obligor.

person or by agent duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are delivered to the Trustee
and, where it is hereby expressly required, to the Company and/or the Guarantor. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this

10

 

Indenture and (subject to Section 601) conclusive in favor of the Trustee, the Company and the
Guarantor, if made in the manner provided in this Section. The Holder of a Global Security may
grant proxies and otherwise authorize any Person, including owners of beneficial interests in such
Global Security, to take any action that a Holder is entitled to take under this Indenture.

          The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

          The ownership of Securities shall be proved by the Security Register.

          Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Security shall bind every future Holder of the same Security and the Holder of every
Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company
and/or the Guarantor in reliance thereon, whether or not notation of such action is made upon such
Security.

          The Company may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give, make or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or direction referred to in
the next paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of the relevant series on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on or prior to
the applicable Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to

11

 

the Trustee in writing and to each Holder of Securities of the relevant series in the manner
set forth in Section 106.

          The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section
512, in each case with respect to Securities of such series. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities of such series on such record date, and no
other Holders, shall be entitled to join in such notice, declaration, request or direction, whether
or not such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date
for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be
cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective
any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the Company in writing
and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

          With respect to any record date set pursuant to this Section, the party hereto which sets such
record dates may designate any day as the “Expiration Date” and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall be
effective unless notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities of the relevant series in the manner set forth in Section
106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which set such record
date shall be deemed to have initially designated the 180th day after such record date as the
Expiration Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than
the 180th day after the applicable record date.

          Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with
regard to any particular Security may do so with regard to all or any part of the principal amount
of such Security or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

          SECTION 105. Notices, Etc., to Trustee, Company and Guarantor.

          Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or
filed with, (1) the Trustee by any Holder or by the Company or the Guarantor shall be sufficient

12

 

for every purpose hereunder if made, given, furnished or filed in writing to or with the
Trustee at its Corporate Trust Office, Attention: Global Corporate Trust, or (2) the Company or the
Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless
otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the
Company or the Guarantor, as the case may be, addressed to it at the address of its principal
office specified in the first paragraph of this instrument or at any other address previously
furnished in writing to the Trustee by the Company or the Guarantor, Attention: Chief Financial
Officer.

          SECTION 106. Notice to Holders; Waiver.

          Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his address as it appears in
the Security Register, not later than the latest date (if any), and not earlier than the earliest
date (if any), prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to
any particular Holder shall affect the sufficiency of such notice with respect to other Holders.
Where this Indenture provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action taken in reliance upon
such waiver.

          In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made with
the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

          SECTION 107. Conflict with Trust Indenture Act.

          If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act which is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes any provision of
the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed
to apply to this Indenture as so modified or to be excluded, as the case may be.

          SECTION 108. Effect of Headings and Table of Contents.

          The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

          SECTION 109. Successors and Assigns.

          All covenants and agreements in this Indenture by the Company and the Guarantor shall bind
their respective successors and assigns, whether so expressed or not.

13

 

          SECTION 110. Separability Clause.

          In case any provision in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

          SECTION 111. Benefits of Indenture.

          Nothing in this Indenture or in the Securities, express or implied, shall give to any Person,
other than the parties hereto and their successors hereunder and the Holders, any benefit or any
legal or equitable right, remedy or claim under this Indenture.

          SECTION 112. Governing Law.

          This Indenture and the Securities shall be governed by and construed in accordance with the
law of the State of New York.

          SECTION 113. Legal Holidays.

          In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any
Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section)) payment of interest
or principal (and premium, if any) need not be made at such Place of Payment on such date, but may
be made on the next succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity.

transferee or transferees.

Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

          If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of
the Officers’ Certificate setting forth the terms of the series.

          SECTION 302. Denominations.

          Unless otherwise specified pursuant to Section 301(16), the Securities of each series shall be
issuable in registered form without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination with respect to the
Securities of any series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.

          SECTION 303. Execution, Authentication, Delivery and Dating.

          The Debt Securities shall be executed on behalf of the Company, and the Guarantees endorsed
thereon shall be executed on behalf of the Guarantor, by their respective Chairman of the Board,
Vice Chairman of the Board, President or one of their Vice Presidents. The signature of any of
these officers on the Debt Securities and/or the Guarantees may be manual or facsimile.

          Securities bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company and the Guarantor, as the case may be, shall bind the Company and
the Guarantor, notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not hold such offices at
the date of such Securities.

          At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Debt Securities of any series executed by the Company, together with the
Guarantees endorsed thereon executed by the Guarantor, to the Trustee for authentication, together
with a Request for the authentication and delivery of such Securities, and the Trustee in
accordance with the Request shall authenticate and deliver such Securities. If the form or terms
of the Securities of the series and Guarantees have been established by or pursuant to one or more
Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

     (1) if the form of such Securities has been established by or pursuant to Board
Resolution as permitted by Section 201, that such form has been established in conformity
with the provisions of this Indenture;

     (2) if the terms of such Securities have been established by or pursuant to Board
Resolution as permitted by Section 301, that such terms have been established in conformity
with the provisions of this Indenture; and

25

 

     (3) that such Securities, when authenticated and delivered by the Trustee and issued by
the Company (with respect to the Debt Securities) and by the Guarantor (with respect to the
Guarantee) in the manner and subject to any conditions specified in such Opinion of Counsel,
will constitute valid and legally binding obligations of the Company and the Guarantor,
respectively, enforceable in accordance with their terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors’ rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be required to authenticate
such Securities if the issue of such Securities pursuant to this Indenture will affect the
Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in
a manner which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Request and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for
all purposes of this Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this Indenture or any related
Guarantee.

          SECTION 304. Temporary Securities.

          Pending the preparation of definitive Securities of any series, the Company and the Guarantor
may execute, and upon Request the Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their execution of such
Securities.

          If temporary Securities of any series are issued, the Company and the Guarantor will cause
definitive Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities

26

 

of such series, the temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such series at the office
or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series, the Company and
the Guarantor shall execute and the Trustee shall authenticate and deliver in exchange therefor one
or more definitive Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as definitive Securities of
such series and tenor.

          SECTION 305. Registration, Registration of Transfer and Exchange.

          The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the register maintained in such office and in any other office or agency of the Company in a Place
of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of Securities as
herein provided.

          Upon surrender for registration of transfer of any Security of a series at the office or
agency of the Company in a Place of Payment for that series, the Company and the Guarantor, as
applicable, shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same series, of any
authorized denominations and of like tenor and aggregate principal amount.

          At the option of the Holder, Securities of any series may be exchanged for other Securities of
the same series, of any authorized denominations and of like tenor and aggregate principal amount,
upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities
are so surrendered for exchange, the Company and the Guarantor, as applicable, shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

          All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company and the Guarantor, as applicable, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities surrendered upon such
registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed

27

 

in connection with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

          If the Securities of any series (or of any series and specified tenor) are to be redeemed in
part, neither the Company nor the Guarantor shall be required (A) to issue, register the transfer
of or exchange any Securities of that series (or of that series and specified tenor, as the case
may be) during a period beginning at the opening of business 15 days before the day of the mailing
of a notice of redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the unredeemed portion
of any Security being redeemed in part.

          The provisions of Clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

     (1) Each Global Security authenticated under this Indenture shall be registered in the
name of the Depositary designated for such Global Security or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and each such
Global Security shall constitute a single Security for all purposes of this Indenture.

     (2) Notwithstanding any other provision in this Indenture, no Global Security may be
exchanged in whole or in part for Securities registered, and no transfer of a Global
Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has
notified the Company and the Guarantor that it is unwilling or unable to continue as
Depositary for such Global Security or (ii) has ceased to be a clearing agency registered
under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default
with respect to such Global Security or (C) there shall exist such circumstances, if any, in
addition to or in lieu of the foregoing as have been specified for this purpose as
contemplated by Section 301.

     (3) Subject to Clause (2) above, any exchange of a Global Security for other Securities
may be made in whole or in part, and all Securities issued in exchange for a Global Security
or any portion thereof shall be registered in such names as the Depositary for such Global
Security shall direct. In connection with the exchange of an entire Global Security for
definitive Securities pursuant to Clause (2), such Global Security shall be deemed to be
surrendered to the Trustee for cancellation, and the Company and the Guarantor shall
execute, and the Trustee shall authenticate and deliver to each beneficial owner identified
by the Depositary in exchange for its beneficial interest in such Global Security, an equal
aggregate principal amount of definitive Securities of authorized denominations. In
addition, if any event specified in Clause (2)(B) shall have occurred and be continuing with
respect to any Global Security, an owner of a beneficial interest in such Global Security
shall have the right to, through the registered Holder of such Global Security, instruct the
Trustee to issue one or more definitive Securities in the amount specified by such owner
(which amount shall not exceed the amount of beneficial interest held by such owner) and to
debit an equivalent amount of beneficial interest in such

28

 

Global Security. Upon receipt of any such instruction, the Trustee shall (i) direct
the Company and the Guarantor to execute such definitive Securities, (ii) authenticate and
deliver such definitive Securities to such owner, and (iii) debit an equivalent amount of
beneficial interest in such Global Security (subject to the rules and procedures of the
Depositary); provided, however, that if the definitive Securities are not issued to any such
beneficial owner promptly after the Trustee has received the foregoing instructions, the
Company and the Guarantor expressly acknowledge, with respect to the right of any Holder to
pursue a remedy pursuant to Section 507 or 508 hereof, the right of any beneficial owner to
pursue such remedy with respect to the portion of the Global Security that represents such
owner’s beneficial interest as if such definitive Securities had been issued.

     (4) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to
this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and
delivered in the form of, and shall be, a Global Security, unless such Security is
registered in the name of a Person other than the Depositary for such Global Security or a
nominee thereof.

          SECTION 306. Additional Provisions Related to Transfer and Exchange of Restricted
Securities.

     (1) If the owner of a beneficial interest in a Rule 144A Global Security that is a
Restricted Security wishes to transfer such interest (or a portion thereof) to a Non-U.S.
Person pursuant to Regulations S, then upon receipt by the Trustee of (i) instructions from
the Holder of the Rule 144A Global Security directing the Trustee to credit or cause to be
credited a beneficial interest in the Regulation S Global Security equal to the principal
amount of the beneficial interest in the Rule 144A Global Security to be transferred and
(ii) a certificate from the transferor in the form of Exhibit A, the Trustee shall, subject
to the rules and procedures of the Depositary, instruct the Depositary to increase the
Regulation S Global Security and decrease the Rule 144A Global Security by the amount so
transferred.

     (2) If the owner of a beneficial interest in a Regulation S Global Security that is a
Restricted Security wishes to transfer such interest (or a portion thereof) to a QIB
pursuant to Rule 144A, then upon receipt by the Trustee of (i) instructions from the Holder
of the Regulation S Global Security directing the Trustee to credit or cause to be credited
a beneficial interest in the Rule 144A Global Security equal to the principal amount of the
beneficial interest in the Regular S Global Note to be transferred and (ii) a certificate
from the transferor in the form of Exhibit B, the Trustee shall, subject to the rules and
procedures of the Depositary, instruct the Depositary to increase the Rule 144A Global
Security and decrease the Regulation S Global Security by the amount so transferred.

     (3) Any transfer of Restricted Securities not described above (other than transfers of
beneficial interests within the same Global Security, which must be effected in accordance
with applicable law and the rules and procedures of the Depositary) shall be made only upon
receipt by the Trustee of such opinions of counsel, certificates and/or

29

 

other information reasonably required by and satisfactory to it in order to ensure
compliance with the Securities Act or in accordance with subsection (d) below.

     (4) Upon the transfer, exchange or replacement of any Security (or a beneficial
interest in a Global Security) bearing a Private Placement Legend, the Trustee shall deliver
only a Security (or a beneficial interest in a Global Security) that bears a Private
Placement Legend unless:

     (i) such Security (or beneficial interest) is exchanged in a Registered
Exchange Offer;

     (ii) such Security (or beneficial interest) is transferred pursuant to an
effective registration statement;

     (iii) such Security (or beneficial interest) is transferred pursuant to Rule
144 upon delivery to the Trustee of a certificate from the transferor in the form of
Exhibit C and an opinion of counsel reasonably satisfactory to the Trustee;

     (iv) such Security (or beneficial interest) is transferred, replaced or
exchanged after the Restriction Termination Date therefor; or

     (v) in connection with such transfer, exchange or replacement, the Trustee
shall have received an opinion of counsel and other evidence reasonably satisfactory
to it to the effect that neither such Private Placement Legend nor the related
restrictions on transfer are required in order to maintain compliance with the
Securities Act.

          SECTION 307. Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee, the Company and the Guarantor, as
applicable, shall execute and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company and the Guarantor, as applicable, shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of
the same series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Security, pay
such Security.

30

 

          Upon the issuance of any new Security under this Section, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

          Every new Security of any series issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company and the Guarantor, as applicable, whether or not the destroyed, lost or stolen Security
shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that series duly issued
hereunder.

          The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Securities.

          SECTION 308. Payment of Interest; Interest Rights Preserved.

          Except as otherwise provided as contemplated by Section 301 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for
such interest.

          Any interest on any Security of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security of such series and the date of the proposed payment, which shall not be earlier
than 20 days after the Trustee receives such notice, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest and the

31

 

Special Record Date therefor to be given to each Holder of Securities of such series in
the manner set forth in Section 106, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on such Special Record Date and shall no longer be
payable pursuant to the following Clause (2).

     (2) The Company may make payment of any Defaulted Interest on the Securities of any
series in any other lawful manner not inconsistent with the requirements of any securities
exchange on which such Securities may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the proposed payment
pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

          SECTION 309. Additional or Special Interest Under Registration Rights Agreements.

          Under certain circumstances, the Company may be obligated to pay additional or special
interest as liquidated damages to Holders of Outstanding Securities of any series, all as and to
the extent set forth in the Registration Rights Agreement (if any) applicable to such series. In
any such event, such additional or special interest the Company may be obligated to pay as
liquidated damages will be deemed to be interest for purposes of this Indenture.

          The Trustee shall have no duty or responsibility for determining if any additional or special
interest or liquidated damages are payable with respect to Securities of any series or, if any such
additional or special interest or liquidated damages are payable thereon, when such additional or
special interest or liquidated damages are payable and the amount thereof. The Company shall
notify the Trustee and Paying Agent in writing at least five days prior to each Interest Payment
Date with respect to Securities of such series whether additional or special interest or liquidated
damages are payable and, to the extent such additional or special interest or liquidated damages
are payable, shall certify in such notice the date such additional or special interest or
liquidated damages commenced to accrue, the applicable per annum interest rate or rates applicable
thereto and the periods such additional or special interest or liquidated damages accrued at each
such rate and the aggregate amount of such additional or special interest or liquidated damages
payable on such Interest Payment Date.

          SECTION 310. Persons Deemed Owners.

          Prior to due presentment of a Security for registration of transfer, the Company, the
Guarantor, the Trustee and any agent thereof may treat the Person in whose name such Security is
registered as the owner of

32

 

such Security for the purpose of receiving payment of principal of and any premium and
(subject to Section 307) any interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Guarantor, the Trustee or any
agent thereof shall be affected by notice to the contrary.

          SECTION 311. Cancellation.

          All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company and/or the
Guarantor may at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which either of them may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder that have not been issued or sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of as directed by a Request, subject to applicable law.

          SECTION 312. Computation of Interest.

          Except as otherwise specified as contemplated by Section 301 for Securities of any series,
interest on the Securities of each series shall be computed on the basis of a 360-day year of
twelve 30-day months.

          SECTION 313. Execution of Guarantee.

          To evidence the Guarantee to the Holders specified in this Indenture, the Guarantor hereby
agrees to execute the Guarantees, in substantially the form attached hereto as Annex A or
in any other form specified in accordance with Section 301 hereof, to be endorsed on each Security
authenticated and delivered by the Trustee (or any Authenticating Agent). Each such Guarantee
shall be signed on behalf of the Guarantor as set forth in Section 303 to the authentication of the
Security on which it is endorsed and the delivery of such Security by the Trustee (or any
Authenticating Agent), after the authentication thereof hereunder, shall constitute due delivery of
such Guarantee on behalf of the Guarantor.

          SECTION 314. Assumption by Guarantor.

          The Guarantor may, without the consent of the Trustee or the Holders, assume all of the rights
and obligations of the Company hereunder with respect to a series of Securities and under the
Securities of such series if, after giving effect to such assumption, no Default or Event of
Default shall have occurred and be continuing. Upon such an assumption, the Guarantor shall
execute a supplemental indenture evidencing its assumption of all such rights and obligations of
the Company and the Company shall be released from its liabilities hereunder and under such
Securities as obligor on the Securities of such series.

          The Guarantor shall assume all of the rights and obligations of the Company hereunder with
respect to a series of Securities and under the

33

 

Securities of such series if, upon a default by the Company in the due and punctual payment of
the principal, sinking fund payment, if any, premium, if any, or interest on such Securities, the
Guarantor is prevented by any court order or judicial proceeding from fulfilling its obligations
under the Guarantee with respect to such series of Securities. Such assumption shall result in the
Securities of such series becoming the direct obligations of the Guarantor and shall be effected
without the consent of the holders of the Securities of any series or the Trustee. Upon such an
assumption, the Guarantor shall execute a supplemental indenture evidencing its assumption of all
such rights and obligations of the Company, and the Company shall be released from its liabilities
hereunder and under such Securities as obligor on the Securities of such series.

ARTICLE FOUR

the Trustee, at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

          (1) either

     (A) all Securities theretofore authenticated and delivered (other than (i)
Securities which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 306 and (ii) Securities for whose payment money has
theretofore been deposited in trust or segregated and held in trust by the Company
and thereafter repaid to the Company or discharged from such trust, as provided in
Section 1003) have been delivered to the Trustee for cancellation; or

     (B) all such Securities not theretofore delivered to the Trustee for
cancellation

     (i) have become due and payable, or

     (ii) will become due and payable at their Stated Maturity within one
year, or

     (iii) are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company,

and the Company and/or the Guarantor, as the case may be, in the case of (i), (ii) or (iii) above,
has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose
money in an amount sufficient to pay and discharge the entire Indebtedness on such Securities not
theretofore delivered to the Trustee for cancellation, for principal and any premium and interest
to the date of such deposit (in the case of Securities which have

34

 

become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

     (2) the Company and/or the Guarantor has paid or caused to be paid all other sums
payable hereunder by them; and

     (3) the Company and/or the Guarantor has delivered to the Trustee an Officers’

Company and the Guarantor to the Trustee under Section 607, the obligations of the Trustee to any
Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of Clause (1) of this Section, the obligations of the Trustee under
Section 402 and the last paragraph of Section 1003 shall survive.

          SECTION 402. Application of Trust Money.

          Subject to the provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company or the Guarantor acting as Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and interest for whose
payment such money has been deposited with the Trustee.

ARTICLE FIVE

Remedies

          SECTION 501. Events of Default.

          “Event of Default”, wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it shall 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 any interest upon any Security of that series when it

warranty a default in whose performance or whose breach is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture solely for
the benefit of series of Securities other than that series), and continuance of such default
or breach for a period of 60 days after there has been given, by registered or certified
mail, to the Company or the Guarantor, as the case may be, by the Trustee or to the Company
or the Guarantor, as the case may be, and the Trustee by the Holders of at least 25% in
principal amount of the Outstanding Securities of that series a written notice specifying
such default or breach and requiring it to be remedied and stating that such notice is a
“Notice of Default” hereunder;

     (5) a default under any bond, debenture, note or other evidence of Indebtedness for

instrument (including this Indenture or any Guarantee) under which there may be issued or by
which there may be secured or evidenced any Indebtedness for money borrowed by the Company,
the Guarantor or any Consolidated Subsidiary having an aggregate principal amount
outstanding of at least $1,000,000,000, whether such Indebtedness now exists or shall
hereafter be created, which default (A) shall constitute a failure to pay any portion of the
principal of such Indebtedness when due and payable after the expiration of any applicable
grace period with respect thereto or (B) shall have resulted in such Indebtedness becoming
or being declared due and payable prior to the date on which it would otherwise have become
due and payable, without, in the case of Clause (A), such Indebtedness having been
discharged or without, in the case of Clause (B), such Indebtedness having been discharged
or such acceleration having been rescinded or annulled, in each such case within a period of
15 days after there shall have been given, by registered or certified mail, to the Company
and the Guarantor by the Trustee or to the Company, the Guarantor and the Trustee by the
Holders of at least 25% in principal amount of the Outstanding Securities of that series a
written notice specifying such default and requiring the Company or the Guarantor, as the
case may be, to cause such Indebtedness to be discharged or cause such acceleration to be
rescinded or annulled, as the case may be, and stating that such notice is a “Notice of
Default” hereunder; or

     (6) the entry by a court having jurisdiction in the premises of (A) a decree or order
for relief in respect of the Company or the Guarantor in an involuntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or (B) a decree or order adjudging the Company or the Guarantor a bankrupt or
insolvent, or approving as properly filed a petition seeking reorganization, arrangement,
adjustment or composition of or in respect of the Company or the Guarantor under any
applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee,
trustee, sequestrator or other similar official of the Company or the Guarantor or of any
substantial part of their respective property, or ordering the winding up or liquidation of
their respective affairs, and the continuance of any such decree or order for relief or any
such other decree or order undismissed or unstayed and in effect for a period of 60
consecutive days; or

36

 

     (7) the commencement by the Company or the Guarantor of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or
the consent by either of them to the entry of a decree or order for relief in respect of the
Company or the Guarantor in an involuntary case or proceeding under any applicable Federal
or State bankruptcy, insolvency, reorganization or other similar law or to the commencement
of any bankruptcy or insolvency case or proceeding against either of them, or the filing by
either of them of a petition or answer or consent seeking reorganization or relief under any
applicable Federal or State law, or the consent by either of them to the filing of such
petition or to the appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or other similar official of the Company or the Guarantor or
of any substantial part of their respective property, or the making by either of them of an
assignment for the benefit of creditors, or the admission by either of them in writing of
the inability to pay their respective debts generally as they become due, or the taking of
corporate action by the Company or the Guarantor in furtherance of any such action; or

     (8) any other Event of Default provided with respect to Securities of that series.

          SECTION 502. Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default (other than an Event of Default specified in Section 501(6) or 501(7))
with respect to Securities of any series at the time Outstanding occurs and is continuing, then in
every such case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount of all the Securities of
that series (or, if any Securities of that series are Original Issue Discount Securities, such
portion of the principal amount of such Securities as may be specified by the terms thereof) to be
due and payable immediately, by a notice in writing to the Company and the Guarantor (and to the
Trustee if given by Holders), and upon any such declaration such principal amount (or specified
amount), together with all accrued and unpaid interest, shall become immediately due and payable.
If an Event of Default specified in Section 501(6) or 501(7) with respect to Securities of any
series at the time Outstanding occurs, the principal amount of all the Securities of that series
(or, if any Securities of that series are Original Issue Discount Securities, such portion of the
principal amount of such Securities as may be specified by the terms thereof), together with all
accrued and unpaid interest, shall automatically, and without any declaration or other action on
the part of the Trustee or any Holder, become immediately due and payable.

          At any time after such a declaration of acceleration with respect to Securities of any series
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Company, the Guarantor and the
Trustee, may rescind and annul such declaration and its consequences if

37

 

     (1) the Company or the Guarantor has paid or deposited with the Trustee a sum
sufficient to pay

     (A) all overdue interest on all Securities of that series,

     (B) the principal of (and premium, if any, on) any Securities of that series
which have become due otherwise than by such declaration of acceleration and any
interest thereon at the rate or rates prescribed therefor in such Securities,

     (C) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate or rates prescribed therefor in such Securities, and

     (D) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel; and

     (2) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which have become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

          SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

          The Company and the Guarantor, jointly and severally, covenant that if

     (1) default is made in the payment of any interest on any Security when such interest
becomes due and payable and such default continues for a period of 30 days, or

     (2) default is made in the payment of the principal of (or premium, if any, on) any
Security at the Maturity thereof,

the Company or the Guarantor will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such Securities for principal
and any premium and interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

          If an Event of Default with respect to Securities of any series occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the

38

 

specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise
of any power granted herein, or to enforce any other proper remedy.

          SECTION 504. Trustee May File Proofs of Claim.

          In case of any judicial proceeding relative to the Company or the Guarantor (or any other
obligor upon the Securities), their respective property or creditors, the Trustee shall be entitled
and empowered, by intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee
allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 607.

          No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding;
provided, however, that the Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other
similar committee.

          SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

          All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in
respect of which such judgment has been recovered.

          SECTION 506. Application of Money Collected.

          Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or any premium or interest, upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

39

 

     FIRST: To the payment of all amounts due the Trustee under Section 607; and

     SECOND: To the payment of the amounts then due and unpaid for principal of and any
premium and interest on the Securities in respect of which or for the benefit of which such
money has been collected, ratably, without preference or priority of any kind, according to
the amounts due and payable on such Securities for principal and any premium and interest,
respectively.

          SECTION 507. Limitation on Suits.

          No Holder of any Security of any series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless

     (1) such Holder has previously given written notice to the Trustee of a continuing
Event of Default with respect to the Securities of that series;

     (2) the Holders of not less than 25% 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 Event of Default in its own name as Trustee hereunder;

     (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the
costs, expenses and liabilities to be incurred in compliance with such request;

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

     (5) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the
Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such Holders.

          SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

          Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of and any
premium and (subject to Section 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption

40

 

Date) and to institute suit for the enforcement of any such payment, and such rights shall not
be impaired without the consent of such Holder.

          SECTION 509. Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Company, the Guarantor, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and thereafter all
rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had
been instituted.

          SECTION 510. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          SECTION 511. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

          SECTION 512. Control by Holders.

          The Holders of a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

     (1) such direction shall not be in conflict with any rule of law or with this
Indenture, and

     (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

          SECTION 513. Waiver of Past Defaults.

          The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series may on behalf of the Holders of all

41

 

the Securities of such series waive any past default hereunder with respect to such series and
its consequences, except a default

     (1) in the payment of the principal of or any premium or interest on any Security of
such series, or

     (2) in respect of a covenant or provision hereof which under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security of such
series affected.

          Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

          SECTION 514. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an assessment in any
suit instituted by the Trustee, the Company or the Guarantor.

          SECTION 515. Waiver of Usury, Stay or Extension Laws.

          The Company and the Guarantor covenant (to the extent that each of them may lawfully do so)
that they will not at any time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and the
Company and the Guarantor (to the extent that each of them may lawfully do so) hereby expressly
waive all benefit or advantage of any such law and covenants that they will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

ARTICLE SIX

The Trustee

          SECTION 601. Certain Duties and Responsibilities.

          The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the

42

 

liability of or affording protection to the Trustee shall be subject to the provisions of this
Section.

          SECTION 602. Notice of Defaults.

          If a default occurs hereunder with respect to Securities of any series, the Trustee shall give
the Holders of Securities of such series notice of such default as and to the extent provided by
the Trust Indenture Act; provided, however, that in the case of any default of the character
specified in Section 501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the purpose of this
Section, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

          SECTION 603. Certain Rights of Trustee.

          Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining from acting
upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of Indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties;

     (2) any request or direction of the Company or the Guarantor mentioned herein shall be
sufficiently evidenced by a Request, and any resolution of the Board of Directors shall be
sufficiently evidenced by a Board Resolution;

     (3) whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any
action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may,
in the absence of bad faith on its part, rely upon one or more Officers’ Certificates;

     (4) the Trustee may consult with counsel and the written advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

     (5) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of Indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or

43

 

investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney, so long as such Trustee, agent or attorney
agrees to reasonable confidentiality provisions not inconsistent with the Trustee’s duties
hereunder;

     (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder;

     (8) before the Trustee acts or refrains from acting, it may require an Officers’
Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it
takes or omits to take in good faith in reliance on such certificate or opinion;

     (9) in no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of
profit) irrespective of whether the Trustee has been advised of the likelihood of such loss
or damage and regardless of the form of action;

     (10) The Trustee shall not be liable for interest on any money received by it, except
as the Trustee may agree with the Company and the Guarantor. Money held in trust by the
Trustee need not be segregated from other funds, except to the extent required by law;

     (11) The Trustee shall not be deemed to have notice of any Default or Event of Default
unless a trust officer has actual knowledge thereof or unless written notice of any event
which is in fact such a default is received by the Trustee at the Corporate Trust Office of
the Trustee, and such notice references the Securities and this Indenture; and

     (12) The rights, privileges, protections, immunities and benefits given to the Trustee
hereunder, including, without limitation, its right to be indemnified, are extended to, and
shall be enforceable by, the Trustee in each of its respective capacities hereunder, and
each agent, custodian and other Person employed to act hereunder.

          SECTION 604. Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company and the Guarantor, as the case may
be, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company or the Guarantor of Securities or the
proceeds thereof.

44

 

          SECTION 605. May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or the Guarantor, in its individual or any other capacity, may become the
owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the
Company and the Guarantor with the same rights it would have if it were not Trustee, Authenticating
Agent, Paying Agent, Security Registrar or such other agent.

          SECTION 606. Money Held in Trust.

          Money held by the Trustee in trust hereunder need not be segregated from other funds except to
the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company or the Guarantor.

          SECTION 607. Compensation and Reimbursement.

          The Company, and if the Company fails to do so, the Guarantor, agrees:

     (1) to pay to the Trustee from time to time reasonable compensation for all services
rendered by it hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence, bad faith or
willful misconduct; and

     (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability
or expense incurred without negligence, bad faith or willful misconduct on its part, arising
out of or in connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or duties
hereunder.

          As security for the performance of the obligations of the Company under this Section, the
Trustee shall have a claim prior to the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the payment of principal of (and premium, if
any) or interest on particular Securities.

          The provisions of this Section 607 shall survive the resignation or removal of the Trustee and
the termination of this Indenture.

45

 

          SECTION 608. Conflicting Interests.

          If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.
To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest
by virtue of being a trustee under this Indenture with respect to Securities of more than one
series.

          SECTION 609. Corporate Trustee Required; Eligibility.

          There shall at all times be one (and only one) Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one or more other
series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act
as such and has a combined capital and surplus of at least $100,000,000 and has an office in New
York, New York. If any such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of its supervising or examining authority, then for the purposes of this
Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of
such Person shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

          SECTION 610. Resignation and Removal; Appointment of Successor.

          No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to
this Article shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611.

          The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company and the Guarantor. If the instrument of acceptance by
a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities
of such series.

          The Trustee may be removed at any time with respect to the Securities of any series by Act of
the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and to the Company.

          If at any time:

     (1) the Trustee shall fail to comply with Section 608 after written request therefor by
the Company, the Guarantor or by any Holder who has been a bona fide Holder of a Security
for at least six months, or

46

 

     (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign
after written request therefor by the Company, the Guarantor or by any such Holder, or

     (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company or the Guarantor, as the case may be, by a Board Resolution
may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder
who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

          If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, with respect to the Securities of one or more series,
the Company or the Guarantor, as the case may be, by a Board Resolution, shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable requirements of
Section 611. If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities
of such series delivered to the Company, the Guarantor and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with
the applicable requirements of Section 611, become the successor Trustee with respect to the
Securities of such series and to that extent supersede the successor Trustee appointed by the
Company or the Guarantor. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company, the Guarantor or the Holders and accepted appointment
in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of
such series for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

          The Company and the Guarantor shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a successor Trustee
with respect to the Securities of any series to all Holders of Securities of such series in the
manner provided in Section 106. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust Office.

47

 

          SECTION 611. Acceptance of Appointment by Successor.

          In case of the appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company,
the Guarantor and to the retiring Trustee an instrument accepting such appointment, and thereupon
the resignation or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the Company, the
Guarantor or the successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

          In case of the appointment hereunder of a successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the Guarantor, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more series shall execute and deliver an
indenture supplemental hereto wherein each successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm
to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which the appointment of
such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that
all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of
that or those series as to which the retiring Trustee is not retiring shall continue to be vested
in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as
shall be necessary to provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee
of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered
by any other such Trustee; and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates; but,
on request of the Company, the Guarantor or any successor Trustee, such retiring Trustee shall duly
assign, transfer and deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

          Upon request of any such successor Trustee, the Company and the Guarantor shall execute any
and all instruments for more fully and certainly vesting in and confirming to such successor
Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph,
as the case may be.

48

 

          No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible under this Article.

          SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

          Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities.

          SECTION 613. Preferential Collection of Claims Against Company.

          If and when the Trustee shall be or become a creditor of the Company or the Guarantor(or any
other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of claims against the Company (or any such other obligor).

          SECTION 614. Appointment of Authenticating Agent.

          The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and the Guarantor and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of
not less than $100,000,000 and subject to supervision or examination by Federal or State authority.
If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. If
at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of
this Section, such

49

 

Authenticating Agent shall resign immediately in the manner and with the effect specified in
this Section.

          Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section,
without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written notice thereof to the
Trustee, the Company and the Guarantor. The Trustee may at any time terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating Agent, the Company and
the Guarantor. Upon receiving such a notice of resignation or upon such a termination, or in case
at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions
of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable
to the Company and the Guarantor and shall give notice of such appointment in the manner provided
in Section 106 to all Holders of Securities of the series with respect to which such Authenticating
Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor hereunder, with like
effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall
be appointed unless eligible under the provisions of this Section.

          The Company and the Guarantor, jointly and severally, but without duplication, agree to pay to
each Authenticating Agent from time to time reasonable compensation for its services under this
Section.

          If an appointment with respect to one or more series is made pursuant to this Section, the
Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternative certificate of authentication in the following form:

          This is one of the Securities of the series designated therein referred to in the within
mentioned Indenture.

as the Commission may be rules and regulations prescribe) which the Company or the Guarantor, as
the case may be, is required to file with the Commission pursuant to Section 13 or Section 15(d) of
the Exchange Act. The Company and the Guarantor shall also comply with the other applicable
provisions of Section 314(a) of the Trust Indenture Act. Notwithstanding any provision of this
Indenture to the contrary, the Company and the Guarantor will not be deemed to have failed to
comply with any of their obligations hereunder for purposes of clause (4) of Section 501 until 90
days after any report referred to in this Section 704 is due.

conferred upon the Company and/or the Guarantor; or

     (3) to add any additional Events of Default for the benefit of the Holders of all or

and with or without interest coupons, or to permit or facilitate the issuance of Securities
in uncertificated form; or

     (5) to add to, change or eliminate any of the provisions of this Indenture in respect
of one or more series of Securities, provided that any such addition, change or elimination
(A) shall neither (i) apply to any Security of any series created prior to the execution of
such supplemental indenture and entitled to the benefit of such provision nor (ii) modify
the rights of the Holder of any such Security with respect to such provision or (B) shall
become effective only when there is no such Security Outstanding; or

     (6) [intentionally omitted]; or

     (7) to establish the form or terms of Securities of any series as permitted by Sections
201 and 301; or

          SECTION 902. Supplemental Indentures With Consent of Holders.

          With the consent of the Holders of not less than 51% in principal amount of the Outstanding
Securities of each series affected by such supplemental indenture, by Act of said Holders delivered
to the Company, the Guarantor and the Trustee, the Company and the Guarantor, when authorized by a
Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities
of such series under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security affected thereby,

     (1) change the Stated Maturity of the principal of, or any installment of principal of
or interest on, any Security, or reduce the principal amount thereof or the rate of interest
thereon or any premium payable upon the redemption thereof, or reduce the amount of the
principal of an Original Issue Discount Security or any other Security which would be due
and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section

any premium or interest thereon is payable, or impair the right to institute suit for

54

 

the enforcement of any such payment on or after the Stated Maturity thereof (or, in the
case of redemption, on or after the Redemption Date), or

     (2) reduce the percentage in principal amount of the Outstanding Securities of any
series, the consent of whose Holders is required for any such supplemental indenture, or the

Indenture, or

     (3) modify any of the provisions of this Section, Section 513 or Section 1005, except
to increase any such percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each Outstanding
Security affected thereby; provided, however, that this clause shall not be
deemed to require the consent of any Holder with respect to changes in the references to
“the Trustee” and concomitant changes in this Section and Section 1005, or the deletion of
this proviso, in accordance with the requirements of Sections 611 and 901(8).

          A supplemental indenture which changes or eliminates any covenant or other provision of this
Indenture which has expressly been included solely for the benefit of one or more particular series
of Securities, or which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to approve the particular
form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve
the substance thereof.

          SECTION 903. Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by this Indenture, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Officers’ Certificate and an Opinion of Counsel each stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise.

          SECTION 904. Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a part of this

          SECTION 906. Reference in Securities to Supplemental Indentures.

          Securities of any series authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company and the Guarantor shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee, the Company and the Guarantor, to any such supplemental
indenture may be prepared and executed by the Company and the Guarantor and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

ARTICLE TEN

Covenants

          SECTION 1001. Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of and any premium and interest on the Securities of that
series in accordance with the terms of the Securities and this Indenture.

          SECTION 1002. Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or more other offices or agencies where
the Securities of one or more series may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Company of its obligation to
maintain an office or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

56

 

          SECTION 1003. Money for Securities Payments to Be Held in Trust.

          If the Company or the Guarantor shall at any time act as Paying Agent with respect to any
series of Securities, it will, on or before each due date of the principal of or any premium or
interest on any of the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to each due date of the principal of or any premium or interest on any Securities of
that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held
as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

          The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company or the Guarantor (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the Securities of that
series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in
trust by such Paying Agent for payment in respect of the Securities of that series.

          The Company or the Guarantor may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Request direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company, the Guarantor or such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were
held by the Company, the Guarantor or such Paying Agent; and, upon such payment by any Paying Agent
to the Trustee, such Paying Agent shall be released from all further liability with respect to such
money.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company or the
Guarantor, in trust for the payment of the principal of or any premium or interest on any Security
of any series and remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company or the Guarantor, as the case may be, on
Request, or (if then held by the Company or the Guarantor) shall be discharged from such trust; and
the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company or the Guarantor for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Company or the Guarantor (as the case
may be) as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Company or the Guarantor cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation in New York, New
York, notice that

57

 

such money remains unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company or the Guarantor (as the case may be).

          SECTION 1004. Statement by Officers as to Default.

          The Company and the Guarantor will each deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company or the Guarantor (as the case may be) ending after the date
hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers
thereof the Company or the Guarantor (as the case may be) is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture or the Guarantees (with
respect to the Guarantees) (without regard to any period of grace or requirement of notice provided
hereunder) and, if the Company or the Guarantor (as the case may be) shall be in default,
specifying all such defaults and the nature and status thereof of which they may have knowledge.

          SECTION 1005. Waiver of Certain Covenants.

          Except as otherwise specified as contemplated by Section 301 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any covenant provided pursuant to Section
301(18), 901(2) or 901(7) for the benefit of the Holders of such series, if before the time for
such compliance the Holders of at least 51% in principal amount of the Outstanding Securities of
such series shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such waiver shall extend
to or affect such term, provision or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and effect.

ARTICLE ELEVEN

Redemption of Securities

          SECTION 1101. Applicability of Article.

          Securities of any series which are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 301
for such Securities) in accordance with this Article.

          SECTION 1102. Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities. In case of any
redemption at the election of the Company of less than all the Securities of any series (including
any such redemption affecting only a single Security), the Company shall, at least 60 days prior to
the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the

58

 

Trustee of such Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such redemption provided in
the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers’ Certificate evidencing compliance with such restriction.

          SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

          If less than all the Securities of any series are to be redeemed (unless all the Securities of
such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by such method as the Trustee shall deem fair and appropriate,
provided that the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized denomination) for such
Security. If less than all the Securities of such series and of a specified tenor are to be
redeemed (unless such redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series and specified tenor not previously called for redemption
in accordance with the preceding sentence.

          The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption as aforesaid and, in case of any Securities selected for partial redemption as
aforesaid, the principal amount thereof to be redeemed.

          The provisions of the two preceding paragraphs shall not apply with respect to any redemption
affecting only a single Security, whether such Security is to be redeemed in whole or in part. In
the case of any such redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security.

          For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to
be redeemed only in part, to the portion of the principal amount of such Securities which has been
or is to be redeemed.

          SECTION 1104. Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed,
at his address appearing in the Security Register.

          All notices of redemption shall state:

          (1) the Redemption Date,

59

 

     (2) the Redemption Price,

     (3) if less than all the Outstanding Securities of any series consisting of more than a
single Security are to be redeemed, the identification (and, in the case of partial
redemption of any such Securities, the principal amounts) of the particular Securities to be
redeemed and, if less than all the Outstanding Securities of any series consisting of a
single Security are to be redeemed, the principal amount of the particular Security to be
redeemed,

     (4) that on the Redemption Date the Redemption Price will become due and payable upon
each such Security to be redeemed and, if applicable, that interest thereon will cease to
accrue on and after said date,

     (5) the place or places where each such Security is to be surrendered for payment of
the Redemption Price, and

     (6) that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company and shall be irrevocable.

          SECTION 1105. Deposit of Redemption Price.

          Prior to any Redemption Date, the Company or the Guarantor shall deposit with the Trustee or
with a Paying Agent (or, if the Company or the Guarantor is acting as Paying Agent, segregate and
hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest
on, all the Securities which are to be redeemed on that date.

          SECTION 1106. Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
or the Guarantor at the Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that, unless otherwise specified as contemplated by Section 301,
installments of interest whose Stated Maturity is on or prior to the Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

          If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium shall, until

60

 

paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

          SECTION 1107. Securities Redeemed in Part.

          Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company, the Guarantor or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company, the Guarantor and the Trustee
duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company
and the Guarantor shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same series and of like
tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount
equal to and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

ARTICLE TWELVE

Sinking Funds

          SECTION 1201. Applicability of Article.

          The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of any series for which a sinking fund is provided except as otherwise specified as
contemplated by Section 301 for such Securities.

          The minimum amount of any sinking fund payment provided for by the terms of any Securities is
herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum
amount provided for by the terms of such Securities is herein referred to as an “optional sinking
fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall
be applied to the redemption of Securities as provided for by the terms of such Securities.

          SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

          The Company (1) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (2) may apply as a credit Securities of a series which have been
redeemed either at the election of the Company pursuant to the terms of such Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund payment with
respect to any Securities of such series required to be made pursuant to the terms of such
Securities as and to the extent provided for by the terms of such Securities; provided that
the Securities to be so credited have not been previously so credited. The Securities to be so
credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as
specified in the Securities so to be redeemed, for redemption through operation of the sinking fund
and the amount of such sinking fund payment shall be reduced accordingly.

61

 

          SECTION 1203. Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund payment date as specified in the terms of a
series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying
the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of
such Securities, the portion thereof, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant
to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Prior to
each such sinking fund payment date as specified in the terms of a series of Securities, the
Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the
manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

ARTICLE THIRTEEN

Defeasance and Covenant Defeasance

          SECTION 1301. Company’s Option to Effect Defeasance or Covenant Defeasance.

          The Company may elect, at its option at any time, to have Section 1302 or Section 1303 applied
to any Securities or any series of Securities, as the case may be, not designated pursuant to
Section 301 as being indefeasible pursuant to such Section 1302 or 1303, in accordance with any
applicable requirements provided pursuant to Section 301 and upon compliance with the conditions
set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in
another manner specified as contemplated by Section 301 for such Securities.

          SECTION 1302. Defeasance and Discharge.

          Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company and the Guarantor shall be
deemed to have been discharged from their respective obligations with respect to such Securities as
provided in this Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the
Company and the Guarantor shall be deemed to have paid and discharged the entire Indebtedness
represented by such Securities and to have satisfied all their respective other obligations under
such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company or the Guarantor, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated or discharged
hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund
described in Section 1304 and as more fully set forth in such Section, payments in respect of the
principal of and any premium and interest on such Securities when payments are due, (2) the
Company’s and Guarantor’s respective obligations with respect to such Securities under Sections
304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Company’s and the Guarantor’s

62

 

obligations in connection therewith and (4) this Article. Subject to compliance with this
Article, the Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have Section 1303 applied
to such Securities.

          SECTION 1303. Covenant Defeasance.

          Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, (1) the Company and the Guarantor shall
be released from their respective obligations under Section 801(3) and any covenants provided
pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such Securities and
(2) the occurrence of any event specified in Sections 501(4) (with respect to any of Section 801(3)
and any such covenants provided pursuant to Section 301(18), 901(2) or 901(7)), 501(5) and 501(8)
shall be deemed not to be or result in an Event of Default, in each case with respect to such
Securities as provided in this Section on and after the date the conditions set forth in Section
1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Company and the Guarantor may omit to
comply with and shall have no liability in respect of any term, condition or limitation set forth
in any such specified Section (to the extent so specified in the case of Section 501(4)), whether
directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason
of any reference in any such Section to any other provision herein or in any other document, but
the remainder of this Indenture and such Securities shall be unaffected thereby.

          SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

          The following shall be the conditions to the application of Section 1302 or Section 1303 to
any Securities or any series of Securities, as the case may be:

     (1) The Company or the Guarantor shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements contemplated
by Section 609 and agrees to comply with the provisions of this Article applicable to it) as
trust funds in trust for the purpose of making the following payments, specifically pledged
as security for, and dedicated solely to, the benefits of the Holders of such Securities,
(A) money in an amount, or (B) U.S. Government Obligations which through the scheduled
payment of principal and interest in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the
Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and
any premium and interest on such Securities on the respective Stated Maturities, in
accordance with the terms of this Indenture and such Securities. As used herein, “U.S.
Government Obligation” means (x) any security which is (i) a direct obligation of the United
States of America for the payment of which the full faith and credit of the United States of
America is pledged or (ii)

63

 

an obligation of a Person controlled or supervised by and acting as an agency or
instrumentality of the United States of America the payment of which is unconditionally
guaranteed as a full faith and credit obligation by the United States of America, which, in
either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof,
and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation which is
specified in Clause (x) above and held by such bank for the account of the holder of such
depositary receipt, or with respect to any specific payment of principal of or interest on
any U.S. Government Obligation which is so specified and held, provided that (except as
required by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depositary receipt from any amount received by the custodian
in respect of the U.S. Government Obligation or the specific payment of principal or
interest evidenced by such depositary receipt.

     (2) In the event of an election to have Section 1302 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of this
instrument, there has been a change in the applicable Federal income tax law, in either case
(A) or (B) to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities will not recognize gain or loss for Federal income tax purposes
as a result of the deposit, Defeasance and discharge to be effected with respect to such
Securities and will be subject to Federal income tax on the same amount, in the same manner
and at the same times as would be the case if such deposit, Defeasance and discharge were
not to occur.

     (3) In the event of an election to have Section 1303 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain
or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance
to be effected with respect to such Securities and will be subject to Federal income tax on
the same amount, in the same manner and at the same times as would be the case if such
deposit and Covenant Defeasance were not to occur.

     (4) The Company shall have delivered to the Trustee an Officer’s Certificate to the
effect that neither such Securities nor any other Securities of the same series, if then
listed on any securities exchange, will be delisted as a result of such deposit.

     (5) No event which is, or after notice or lapse of time or both would become, an Event
of Default with respect to such Securities or any other Securities shall have occurred and
be continuing at the time of such deposit or, with regard to any such event specified in
Sections 501(6) or (7), at any time on or prior to the 90th day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied until
after such 90th day).

     (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a
conflicting interest within the meaning of the Trust

64

 

Indenture Act (assuming all Securities are in default within the meaning of such Act).

     (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation
of, or constitute a default under, any other agreement or instrument to which the Company or
the Guarantor is a party or by which it is bound.

     (8) Such Defeasance or Covenant Defeasance shall not result in the trust arising from
such deposit constituting an investment company within the meaning of the Investment Company
Act unless such trust shall be registered under such Act or exempt from registration
thereunder.

     (9) The Company shall have delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that all conditions precedent with respect to such
Defeasance or Covenant Defeasance have been complied with.

          SECTION 1305. Deposited Money and U.S. Government Obligations to Be Held in Trust;
Miscellaneous Provisions.

          Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 1304 in respect of any Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company or Guarantor acting as Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in respect of principal and
any premium and interest, but money so held in trust need not be segregated from other funds except
to the extent required by law.

          The Company or the Guarantor, as the case may be, shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the Holders of
Outstanding Securities.

          Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company or the Guarantor from time to time upon Request any money or U.S. Government
Obligations held by it as provided in Section 1304 with respect to any Securities which, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount thereof which would
then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may
be, with respect to such Securities.

          SECTION 1306. Reinstatement.

          If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining,

65

 

restraining or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company and the Guarantor have been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had
occurred pursuant to this Article with respect to such Securities, until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect
to such Securities in accordance with this Article; provided, however, that if the
Company or the Guarantor makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of obligations, the Company and/or the Guarantor shall be
subrogated to the rights (if any) of the Holders of such Securities to receive such payment from
the money so held in trust.

          This instrument may be executed in any number of counterparts, each of which so executed shall
be deemed to be an original, but all such counterparts shall together constitute but one and the
same instrument.

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as
of the day and year first above written.

Annex A

FORM OF GUARANTEE

BERKSHIRE HATHAWAY INC.

          FOR VALUE RECEIVED, Berkshire Hathaway Inc., a Delaware corporation (the “Guarantor”), hereby
absolutely, unconditionally and irrevocably guarantees to the holders (the “Holders”) of any
security authenticated and delivered (each a “Security”) by The Bank of New York Trust Company,
N.A., as trustee (the “Trustee”) under that certain Indenture, dated as of March 20, 2007 (the
“Indenture”), among the Trustee, the Guarantor and XTRA Finance Corporation, a Delaware corporation
(“Issuer”), the full and prompt payment when due (whether at stated maturity, by acceleration or
otherwise) of all present and future payment obligations of the Issuer pursuant to the terms of
such Security and/or the Indenture, whether direct or indirect, absolute or contingent, and whether
for principal, interest, fees, expenses, indemnification or otherwise (collectively, the
“Obligations”). Nothing herein shall be deemed to guarantee any obligation of the Issuer other
than the Obligations. Nothing herein shall be deemed to guarantee any obligation of any person or
entity other than the Issuer.

          The Guarantor’s obligations hereunder shall be unconditional and absolute, and shall not be
released, discharged or otherwise affected by (i) the existence, validity, enforceability,
perfection or extent of any collateral therefor, (ii) any lack of validity or enforceability of any
provision of the Security or the Indenture, (iii) any liquidation, bankruptcy, insolvency,
reorganization or other similar proceeding affecting the Issuer or its assets, or (iv) any other
circumstance relating to the Obligations that might otherwise constitute a legal or equitable
discharge of, or defense to, the Guarantor. The Guarantor agrees that the Holders and/or the
Trustee may resort to the Guarantor, as primary obligor and not merely as surety, for payment of
any of the Obligations whether or not the Holders or the Trustee shall have proceeded against the
Issuer or any other obligor principally or secondarily obligated with respect to any of the
Obligations. Neither the Holders nor the Trustee shall be obligated to file any claim relating to
any of the Obligations in the event that the Issuer becomes subject to a bankruptcy, reorganization
or similar proceeding, and the failure of the Holders or the Trustee to so file shall not affect
the Guarantor’s obligations hereunder. In the event that any payment to the Holders by the Issuer
in respect of any Obligations is rescinded or must otherwise be returned for any reason whatsoever,
the Guarantor shall remain liable hereunder with respect to such Obligations as if such payment had
not been made.

          The Guarantor agrees that, subject to the Indenture, the Holders and/or the Trustee may at any
time and from time to time, either before or after the maturity thereof, without notice to or
further consent of the Guarantor, extend the time of payment of, exchange or surrender any
collateral for, or renew any of the Obligations, and may also make any agreement with the Issuer or
with any other party to or person liable on any of the Obligations or interested therein, for the
extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for
any modification of the terms thereof or of any agreement between the Holders, the Trustee and the
Issuer or any such other party or person, and that none of the foregoing shall in any way impair or
affect this Guarantee.

67

 

The Guarantor hereby unconditionally and irrevocably waives, to the fullest extent permitted
by law, (a) notice of the acceptance of this Guarantee and of the Obligations, presentment, demand
for payment, notice of dishonor and protest, (b) any requirement that any Holder exhaust any right
or take any action against the Issuer, and (c) any right to revoke this Guarantee.

          The Guarantor agrees to pay on demand all fees and out-of-pocket expenses incurred by the
Holders or the Trustee in any way relating to the enforcement or protection of the rights of the
Holders and/or the Trustee hereunder.

          Upon payment of any of the Obligations, the Guarantor shall be subrogated to the rights of the
Holders and/or the Trustee against the Issuer with respect to such Obligations, and the Holders and
the Trustee agree to take such steps, at the Guarantor’s expense, as the Guarantor may reasonably
request to implement such subrogation; provided, however, that the Guarantor shall not be entitled
to enforce, or to receive any payments arising out of or based upon, such right of subrogation
during any period in which any amount payable by the Issuer under the Security or the Indenture is
overdue or unpaid.

          No failure on the part of the Holders or the Trustee to exercise, and no delay in exercising,
any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise by the Holders or the Trustee of any right, remedy or power hereunder preclude any
other or future exercise of any right, remedy or power. Each and every right, remedy and power
hereby granted to the Holders or the Trustee or allowed any of them by law or other agreement shall
be cumulative and not exclusive of any other, and may be exercised by the Holders or the Trustee at
any time or from time to time.

          The Guarantor hereby represents and warrants that:

          (a) the Guarantor is duly organized, validly existing and in good standing as a corporation
under the laws of the State of Delaware and has full corporate power to execute, deliver and
perform this Guarantee;

          (b) the execution, delivery and performance of this Guarantee have been and remain duly
authorized by all necessary corporate action and do not contravene any provision of the Guarantor’s
certificate of incorporation or by-laws, as amended to date, or any law, regulation, rule, decree,
order, judgment or contractual restriction binding on the Guarantor or its assets;

          (c) all consents, licenses, clearances, authorizations and approvals of, and registrations
and declarations with, any governmental authority or regulatory body necessary for the due
execution, delivery and performance of this Guarantee have been obtained and remain in full force
and effect and all conditions thereof have been duly complied with, and no other action by, and no
notice to or filing with, any governmental authority or regulatory body is required in connection
with the execution, delivery or performance of this Guarantee;

          (d) this Guarantee constitutes a legal, valid and binding obligation of the Guarantor
enforceable against the Guarantor in accordance with its terms, subject to bankruptcy, insolvency,
reorganization, moratorium

68

 

and other laws of general applicability relating to or affecting creditors’ rights and to
general equity principles; and

          (e) there are no actions, suits or arbitration proceedings pending or, to the knowledge of
the Guarantor, threatened against it, at law or in equity, which, individually or in the aggregate,
if adversely determined, would materially adversely affect the financial condition of the Guarantor
or materially impair its ability to perform its obligations under this Guarantee.

          The Guarantor may not assign its obligations hereunder to any person (except as permitted by
the Indenture) without the prior written consent of the Holders or the Trustee.

          All payments by the Guarantor to the Holders or the Trustee shall be made in accordance with
the provisions of the Indenture and the Security; provided, however, that payment of any fees or
expenses pursuant to the fourth paragraph hereof shall be made by wire transfer of immediately
available funds to an account at a commercial bank in the United States specified to the Guarantor
at least ten (10) days in advance of any demand for payment by the Holders or the Trustee.

          All notices or demands on the Guarantor shall be deemed effective when received, shall be in
writing and shall be delivered by hand or by registered mail, or by facsimile transmission promptly
confirmed by registered mail, addressed to the Guarantor at:

Berkshire Hathaway Inc.

1440 Kiewit Plaza

Omaha, NE 68131

Attention: Chief Financial Officer

Facsimile: (402) 346-3375

or to such other addresses or facsimile numbers as the Guarantor shall have notified the Holders or
the Trustee in a written notice delivered in accordance with the Indenture.

          This Guarantee shall remain in full force and effect and shall be binding on the Guarantor,
its successors and assigns until all of the Obligations have been satisfied in full.

          This Guarantee shall be governed by, and construed in accordance with, the laws of the State
of New York applicable to contracts made and to be performed solely within such State.

          No amendment or waiver of any provision of this Guarantee shall in any event be effective
unless the same shall be in writing and signed by the Trustee and the Guarantor.

          If for any reason any provision or provisions hereof are determined to be invalid and contrary
to any existing or future law, such invalidity shall not, to the fullest extent permitted by law,
impair the operation of or effect of those portions of this Guarantee that are valid.

69

 

          THE GUARANTOR WAIVES ANY RIGHT IT MAY HAVE TO A JURY TRIAL IN CONNECTION WITH ANY ACTION, SUIT
OR PROCEEDING ARISING OUT OF OR RELATED IN ANY WAY TO THIS GUARANTEE.

Rule 144A Global Security to Regulation S Global Security

(transfers pursuant to Section 306(a) of the Indenture)

[Date]

The Bank of New York Trust

New York, NY 10286

	 	 	      Re: [Note][Debenture][Zero Coupon] Due                      (the “Securities”) of XTRA
Finance Corporation (the “Company”)

Ladies and Gentlemen:

          Reference is hereby made to the Indenture, dated as of March 20, 2007 (as amended and
supplemented from time to time, the “Indenture”), among the Company, as issuer, Berkshire Hathaway
Inc., as guarantor (the “Guarantor”), and The Bank of New York Trust Company, N.A., as trustee (the
“Trustee”). Capitalized terms used but not defined herein shall have the meanings given them in
the Indenture.

          This letter relates to $                     principal amount of Securities which are held by the
undersigned (the “Transferor”) as a beneficial interest in the Rule 144A Global Security (CUSIP No.
                    ) deposited with [Name of Depositary] (the “Depositary”). The Transferor has
requested a transfer of such beneficial interest for an interest in the Regulation S Global
Security (CUSIP No.                     ) deposited with the Depositary.

          In connection with such request and in respect of such Securities, the Transferor hereby
certifies that such transfer has been effected pursuant to and in accordance with Regulation S and
accordingly further certifies that:

	 	(a)	 	the offer of the Securities was not made to a person in the
United States;
	 
	 	(b)	 	either (i) at the time the buy order was originated, the
transferee was outside the United States or the Transferor and any person
acting on its behalf reasonably believed that the transferee was outside the
United States or (ii) the transaction was executed in, on or through the
facilities of a designated off-shore securities market and neither the
Transferor nor any person acting on its behalf knows that the transaction has
been pre-arranged with a buyer in the United States;
	 
	 	(c)	 	no directed selling efforts have been made in the United States
in contravention of the requirements of Rule 903(b) or Rule 904(b) of
Regulation S, as applicable;

A-1

 

	 	(d)	 	the transaction is not part of a plan or scheme to evade the
registration requirements of the Securities Act; and
	 
	 	(e)	 	the Transferor is the beneficial owner of the Securities being
transferred.

          In addition, if the transfer is made during the distribution compliance period specified in
