ISSUE, DESCRIPTION, EXECUTION, REGISTRATION AND EXCHANGE OF NOTES

SECTION 2.01.  DESIGNATION AMOUNT AND ISSUE OF NOTES.  THE NOTES SHALL BE
DESIGNATED AS THE “3.625% CONVERTIBLE SENIOR NOTES DUE 2011.”  UPON THE
EXECUTION OF THIS INDENTURE, AND FROM TIME TO TIME THEREAFTER, NOTES MAY BE
EXECUTED BY THE ISSUER AND DELIVERED TO THE TRUSTEE FOR AUTHENTICATION, AND THE
TRUSTEE SHALL THEREUPON AUTHENTICATE AND DELIVER NOTES UPON A WRITTEN ORDER OF
THE ISSUER, SUCH ORDER SIGNED BY TWO OFFICERS, WITHOUT ANY FURTHER ACTION BY THE
ISSUER HEREUNDER.

The aggregate principal amount of Notes which may be authenticated and delivered
under this Indenture is initially limited to $250,000,000 (or $287,500,000 if
the Initial Purchasers’ option set forth in the Purchase Agreement is exercised
in full).  The Issuer may, without the consent of the holders of Notes, issue
additional debt securities (the “Additional Notes”) from time to time in the
future with the same terms, except for any difference in the issue price and
interest accrued prior to the issue date of the Additional Notes, and with the
same CUSIP number as the Notes originally issued under this Indenture (the
“Initial Notes”) in an unlimited principal amount, provided that such Additional
Notes must be part of the same issue as the Initial Notes for United States
federal income tax purposes.  The Initial Notes and any such Additional Notes
will constitute a single series of debt securities, and in circumstances in
which this Indenture provides for the holders of Notes to vote or take any
action, the holders of Initial Notes and the holders of any such Additional
Notes will vote or take that action as a single class.

SECTION 2.02.  FORM OF NOTES.  THE NOTES AND THE TRUSTEE’S CERTIFICATE OF
AUTHENTICATION TO BE BORNE BY SUCH NOTES SHALL BE SUBSTANTIALLY IN THE FORM SET
FORTH IN EXHIBIT A HERETO.  THE TERMS AND PROVISIONS CONTAINED IN THE FORM OF
NOTE ATTACHED AS EXHIBIT A HERETO SHALL CONSTITUTE, AND ARE HEREBY EXPRESSLY
MADE, A PART OF THIS INDENTURE AND, TO THE EXTENT APPLICABLE, THE ISSUER AND THE
TRUSTEE, BY THEIR EXECUTION AND DELIVERY OF THIS INDENTURE, EXPRESSLY AGREE TO
SUCH TERMS AND PROVISIONS AND TO BE BOUND THEREBY.

Any of the Notes may have such letters, numbers or other marks of identification
and such notations, legends, endorsements or changes as the officers executing
the same may approve (execution thereof to be conclusive evidence of such
approval) and as are not

8

--------------------------------------------------------------------------------

inconsistent with the provisions of this Indenture, or as may be required by the
Custodian, the Depositary or by the National Association of Securities Dealers,
Inc. in order for the Notes to be tradable on The PORTAL Market or as may be
required for the Notes to be tradable on any other market developed for trading
of securities pursuant to Rule 144A or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any securities exchange or automated quotation system on
which the Notes may be listed, or to conform to usage, or to indicate any
special limitations or restrictions to which any particular Notes are subject.

So long as the Notes are eligible for book-entry settlement with the Depositary,
or unless otherwise required by law, or otherwise contemplated by Section
2.05(b), all of the Notes will be represented by one or more Notes in global
form registered in the name of the Depositary or the nominee of the Depositary
(a “Global Note”).  The transfer and exchange of beneficial interests in any
such Global Note shall be effected through the Depositary in accordance with
this Indenture and the applicable procedures of the Depositary.  Except as
provided in Section 2.05(b), beneficial owners of a Global Note shall not be
entitled to have certificates registered in their names, will not receive or be
entitled to receive physical delivery of certificates in definitive form and
will not be considered holders of such Global Note.

Any Global Note shall represent such of the outstanding Notes as shall be
specified therein and shall provide that it shall represent the aggregate amount
of outstanding Notes from time to time endorsed thereon and that the aggregate
amount of outstanding Notes represented thereby may from time to time be
increased or reduced to reflect redemptions, repurchases, conversions, exchanges
or transfers permitted hereby.  Any endorsement of a Global Note to reflect the
amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the
direction of the Trustee, in such manner and upon instructions given by the
holder of such Notes in accordance with this Indenture.  Payment of principal
of, and interest on, any Global Note shall be made to the holder of such Note.

SECTION 2.03.  DATE AND DENOMINATION OF NOTES; PAYMENTS OF INTEREST.  THE NOTES
SHALL BE ISSUABLE IN REGISTERED FORM WITHOUT COUPONS IN DENOMINATIONS OF $1,000
PRINCIPAL AMOUNT AND INTEGRAL MULTIPLES THEREOF.  EACH NOTE SHALL BE DATED THE
DATE OF ITS AUTHENTICATION AND SHALL BEAR INTEREST FROM THE DATE SPECIFIED ON
THE FACE OF THE FORM OF NOTE ATTACHED AS EXHIBIT A HERETO.  INTEREST ON THE
NOTES SHALL BE COMPUTED ON THE BASIS OF A 360-DAY YEAR CONSISTING OF TWELVE
30-DAY MONTHS.

The Person in whose name any Note (or its Predecessor Note) is registered on the
Note Register at the close of business, New York City time, on any Record Date
with respect to any Interest Payment Date shall be entitled to receive the
interest payable on such Interest Payment Date; provided that interest payable
on the Stated Maturity shall be payable to the Person to whom principal is
payable; and provided, further that if an Interest Payment Date falls on or
prior to a Redemption Date or a Change in Control Repurchase Date, as the case
may be, the semi-annual payment of interest becoming due on such Interest
Payment Date shall be payable to the holder of such Note registered as such on
the related Record Date.  Interest shall be payable at the office of the Issuer
maintained by the Issuer for such purposes in the Borough of Manhattan, The City
of New York, which shall initially be an office or agency of the Trustee.

9

--------------------------------------------------------------------------------

The Issuer shall pay interest (i) on any Notes in certificated form by check
mailed to the address of the Person entitled thereto as it appears in the Note
Register; provided, however, that a holder of any Notes in certificated form in
the aggregate principal amount of more than $5.0 million may specify by written
notice to the Issuer that it pay interest by wire transfer of immediately
available funds to the account specified by the Noteholder in such notice, or
(ii) on any Global Note by wire transfer of immediately available funds to the
account of the Depositary or its nominee.  If a payment date is not a Business
Day, payment shall be made on the next succeeding Business Day, and no
additional interest shall accrue thereon.  The term “Record Date” with respect
to any Interest Payment Date shall mean the March 1 or the September 1, in each
case whether or not such day is a Business Day, next preceding the applicable
Interest Payment Date.  Interest payable on each Interest Payment Date or any
other date on which interest shall be payable shall equal the amount of interest
accrued for the period from and including the immediately preceding Interest
Payment Date in respect of which interest has been paid (or from and including
October 12, 2006 if no interest shall have been payable) to but excluding such
Interest Payment Date or other date on which such interest should be payable.

Any interest on any Note 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 Noteholder registered as such on the
relevant Record Date, and such Defaulted Interest shall be paid by the Issuer,
at its election in each case, as provided in clause (1) or (2) below:

(1)           THE ISSUER MAY ELECT TO MAKE PAYMENT OF ANY DEFAULTED INTEREST TO
THE PERSONS IN WHOSE NAMES THE NOTES (OR THEIR RESPECTIVE PREDECESSOR NOTES) ARE
REGISTERED AT THE CLOSE OF BUSINESS, NEW YORK CITY TIME, ON A SPECIAL RECORD
DATE FOR THE PAYMENT OF SUCH DEFAULTED INTEREST, WHICH SHALL BE FIXED IN THE
FOLLOWING MANNER.  THE ISSUER SHALL NOTIFY THE TRUSTEE IN WRITING OF THE AMOUNT
OF DEFAULTED INTEREST PROPOSED TO BE PAID ON EACH NOTE AND THE DATE OF THE
PROPOSED PAYMENT (WHICH SHALL BE NOT LESS THAN TWENTY FIVE (25)  CALENDAR DAYS
AFTER THE RECEIPT BY THE TRUSTEE OF SUCH NOTICE, UNLESS THE TRUSTEE SHALL
CONSENT TO AN EARLIER DATE), AND AT THE SAME TIME THE ISSUER SHALL DEPOSIT WITH
THE TRUSTEE AN AMOUNT OF MONEY EQUAL TO THE AGGREGATE AMOUNT TO BE PAID IN
RESPECT OF SUCH DEFAULTED INTEREST OR SHALL MAKE ARRANGEMENTS SATISFACTORY TO
THE TRUSTEE FOR SUCH DEPOSIT ON OR 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 FIFTEEN (15) CALENDAR DAYS AND NOT LESS
THAN TEN (10) CALENDAR DAYS PRIOR TO THE DATE OF THE PROPOSED PAYMENT, AND NOT
LESS THAN TEN (10) CALENDAR DAYS AFTER THE RECEIPT BY THE TRUSTEE OF THE NOTICE
OF THE PROPOSED PAYMENT (UNLESS, THE TRUSTEE SHALL CONSENT TO AN EARLIER DATE). 
THE TRUSTEE SHALL PROMPTLY NOTIFY THE ISSUER OF SUCH SPECIAL RECORD DATE AND, IN
THE NAME AND AT THE EXPENSE OF THE ISSUER, SHALL CAUSE NOTICE OF THE PROPOSED
PAYMENT OF SUCH DEFAULTED INTEREST AND THE SPECIAL RECORD DATE THEREFOR TO BE
MAILED, FIRST-CLASS POSTAGE PREPAID, TO EACH HOLDER AT ITS ADDRESS AS IT APPEARS
IN THE NOTE REGISTER, NOT LESS THAN TEN CALENDAR DAYS PRIOR TO SUCH SPECIAL
RECORD DATE (UNLESS, THE TRUSTEE SHALL CONSENT TO AN EARLIER 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 NOTES (OR THEIR RESPECTIVE PREDECESSOR NOTES) ARE
REGISTERED AT THE CLOSE OF BUSINESS, NEW YORK CITY TIME, ON SUCH SPECIAL RECORD
DATE AND SHALL NO LONGER BE PAYABLE PURSUANT TO THE FOLLOWING CLAUSE (2) OF THIS
SECTION 2.03.

10

--------------------------------------------------------------------------------

(2)           THE ISSUER MAY MAKE PAYMENT OF ANY DEFAULTED INTEREST IN ANY OTHER
LAWFUL MANNER NOT INCONSISTENT WITH THE REQUIREMENTS OF ANY SECURITIES EXCHANGE
OR AUTOMATED QUOTATION SYSTEM ON WHICH THE NOTES MAY BE LISTED OR DESIGNATED FOR
ISSUANCE, AND UPON SUCH NOTICE AS MAY BE REQUIRED BY SUCH EXCHANGE OR AUTOMATED
QUOTATION SYSTEM, IF, AFTER NOTICE GIVEN BY THE ISSUER TO THE TRUSTEE OF THE
PROPOSED PAYMENT PURSUANT TO THIS CLAUSE, SUCH MANNER OF PAYMENT SHALL BE DEEMED
PRACTICABLE BY THE TRUSTEE.

SECTION 2.04.  EXECUTION OF NOTES.  THE NOTES SHALL BE SIGNED IN THE NAME AND ON
BEHALF OF THE ISSUER BY THE MANUAL OR FACSIMILE SIGNATURE OF AN OFFICER.  ONLY
SUCH NOTES AS SHALL BEAR THEREON A CERTIFICATE OF AUTHENTICATION SUBSTANTIALLY
IN THE FORM SET FORTH ON THE FORM OF NOTE ATTACHED AS EXHIBIT A HERETO, MANUALLY
EXECUTED BY THE TRUSTEE (OR AN AUTHENTICATING AGENT APPOINTED BY THE TRUSTEE AS
PROVIDED BY SECTION 15.11), SHALL BE ENTITLED TO THE BENEFITS OF THIS INDENTURE
OR BE VALID OR OBLIGATORY FOR ANY PURPOSE.  SUCH CERTIFICATE BY THE TRUSTEE (OR
SUCH AN AUTHENTICATING AGENT) UPON ANY NOTE EXECUTED BY THE ISSUER SHALL BE
CONCLUSIVE EVIDENCE THAT THE NOTE SO AUTHENTICATED HAS BEEN DULY AUTHENTICATED
AND DELIVERED HEREUNDER AND THAT THE HOLDER IS ENTITLED TO THE BENEFITS OF THIS
INDENTURE.

In case any Officer who shall have signed any of the Notes shall cease to be
such Officer before the Notes so signed shall have been authenticated and
delivered by the Trustee, or disposed of by the Issuer, such Notes nevertheless
may be authenticated and delivered or disposed of as though the person who
signed such Notes had not ceased to be such Officer, and any Note may be signed
on behalf of the Issuer by such persons as, at the actual date of the execution
of such Note, shall be the proper Officers, although at the date of the
execution of this Indenture any such person was not such an Officer.

SECTION 2.05.  EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES; RESTRICTIONS ON
TRANSFER.  (A)  THE ISSUER SHALL CAUSE TO BE KEPT AT THE CORPORATE TRUST OFFICE
A REGISTER (THE REGISTER MAINTAINED IN SUCH OFFICE AND IN ANY OTHER OFFICE OR
AGENCY OF THE ISSUER DESIGNATED PURSUANT TO SECTION 4 BEING HEREIN SOMETIMES
COLLECTIVELY REFERRED TO AS THE “NOTE REGISTER”) IN WHICH, SUBJECT TO SUCH
REASONABLE REGULATIONS AS IT MAY PRESCRIBE, THE ISSUER SHALL PROVIDE FOR THE
REGISTRATION OF NOTES AND OF TRANSFERS OF NOTES.  THE NOTE REGISTER SHALL BE IN
WRITTEN FORM OR IN ANY FORM CAPABLE OF BEING EXCHANGED INTO WRITTEN FORM WITHIN
A REASONABLY PROMPT PERIOD OF TIME.  THE TRUSTEE IS HEREBY APPOINTED “NOTE
REGISTRAR” FOR THE PURPOSE OF REGISTERING NOTES AND TRANSFERS OF NOTES AS HEREIN
PROVIDED. THE ISSUER MAY APPOINT ONE OR MORE CO-REGISTRARS IN ACCORDANCE WITH
SECTION 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or
any co-registrar, and satisfaction of the requirements for such transfer set
forth in this Section 2.05, the Issuer shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes of any authorized denominations and of a like
aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a
like aggregate principal amount, upon surrender of the Notes to be exchanged at
any such office or agency maintained by the Issuer pursuant to Section 4.02. 
Whenever any Notes are so surrendered for exchange, the Issuer shall execute,
and the Trustee shall authenticate and deliver,

11

--------------------------------------------------------------------------------

the Notes which the Noteholder making the exchange is entitled to receive
bearing registration numbers not contemporaneously outstanding.

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

All Notes presented or surrendered for registration of transfer or exchange,
repurchase or conversion shall (if so required by the Issuer or the Note
Registrar) be duly endorsed, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Issuer, and the Notes shall
be duly executed by the Noteholder thereof or its attorney duly authorized in
writing.

No service charge shall be made to any holder for any registration of transfer
or exchange of Notes, but the Issuer may require payment by the holder of a sum
sufficient to cover any tax, assessment or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Notes.

In connection with the redemption of the Notes in part, neither the Trustee nor
any Note Registrar shall be required to issue or register the transfer or
exchange of (a) any Notes during a period beginning at the opening of business
fifteen (15) days before any selection of Notes to be redeemed and ending at the
close of business on the day of mailing of the relevant notice of redemption, or
(b) any Notes or portions thereof called for redemption pursuant to Section
3.02, except the unredeemed portion of any Note redeemed in part.

(B)           THE FOLLOWING PROVISIONS SHALL APPLY ONLY TO GLOBAL NOTES:

(I)            EACH GLOBAL NOTE AUTHENTICATED UNDER THIS INDENTURE SHALL BE
REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE THEREOF AND DELIVERED TO
SUCH DEPOSITARY OR A NOMINEE THEREOF OR CUSTODIAN THEREFOR, AND EACH SUCH GLOBAL
NOTE SHALL CONSTITUTE A SINGLE NOTE FOR ALL PURPOSES OF THIS INDENTURE.

(II)           NOTWITHSTANDING ANY OTHER PROVISION IN THIS INDENTURE, NO GLOBAL
NOTE MAY BE EXCHANGED IN WHOLE OR IN PART FOR NOTES REGISTERED, AND NO TRANSFER
OF A GLOBAL NOTE IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY
PERSON OTHER THAN THE DEPOSITARY OR A NOMINEE THEREOF UNLESS (1) THE DEPOSITARY
(X) HAS NOTIFIED THE ISSUER THAT IT IS UNWILLING OR UNABLE TO CONTINUE AS
DEPOSITARY FOR SUCH GLOBAL NOTE OR (Y) HAS CEASED TO BE A CLEARING AGENCY
REGISTERED UNDER THE EXCHANGE ACT, AND A SUCCESSOR DEPOSITARY HAS NOT BEEN
APPOINTED BY THE ISSUER WITHIN NINETY (90) CALENDAR DAYS, (2) AN EVENT OF
DEFAULT HAS OCCURRED AND IS CONTINUING OR (3) THE ISSUER, IN ITS SOLE
DISCRETION, NOTIFIES THE TRUSTEE IN WRITING THAT IT NO LONGER WISHES TO HAVE ALL
THE NOTES REPRESENTED BY GLOBAL NOTES.  ANY GLOBAL NOTE EXCHANGED PURSUANT TO
CLAUSE (1) OR (2) ABOVE SHALL BE SO EXCHANGED IN WHOLE AND NOT IN PART AND ANY
GLOBAL NOTE EXCHANGED PURSUANT TO CLAUSE (3) ABOVE MAY BE EXCHANGED IN WHOLE OR
FROM TIME TO TIME IN PART AS DIRECTED BY THE ISSUER.  ANY NOTE ISSUED IN
EXCHANGE FOR A GLOBAL NOTE OR ANY PORTION THEREOF SHALL BE A GLOBAL NOTE;
PROVIDED THAT ANY SUCH NOTE SO ISSUED THAT IS REGISTERED IN THE NAME OF A PERSON
OTHER THAN THE DEPOSITARY OR A NOMINEE THEREOF SHALL NOT BE A GLOBAL NOTE.

12

--------------------------------------------------------------------------------

(III)          NOTES ISSUED IN EXCHANGE FOR A GLOBAL NOTE OR ANY PORTION THEREOF
PURSUANT TO CLAUSE (II) ABOVE SHALL BE ISSUED IN DEFINITIVE, FULLY REGISTERED
FORM, WITHOUT INTEREST COUPONS, SHALL HAVE AN AGGREGATE PRINCIPAL AMOUNT EQUAL
TO THAT OF SUCH GLOBAL NOTE OR PORTION THEREOF TO BE SO EXCHANGED, SHALL BE
REGISTERED IN SUCH NAMES AND BE IN SUCH AUTHORIZED DENOMINATIONS AS THE
DEPOSITARY SHALL DESIGNATE AND SHALL BEAR ANY LEGENDS REQUIRED HEREUNDER.  ANY
GLOBAL NOTE TO BE EXCHANGED IN WHOLE SHALL BE SURRENDERED BY THE DEPOSITARY TO
THE TRUSTEE, AS NOTE REGISTRAR.  WITH REGARD TO ANY GLOBAL NOTE TO BE EXCHANGED
IN PART, EITHER SUCH GLOBAL NOTE SHALL BE SO SURRENDERED FOR EXCHANGE OR, IF THE
TRUSTEE IS ACTING AS CUSTODIAN FOR THE DEPOSITARY OR ITS NOMINEE WITH RESPECT TO
SUCH GLOBAL NOTE, THE PRINCIPAL AMOUNT THEREOF SHALL BE REDUCED, BY AN AMOUNT
EQUAL TO THE PORTION THEREOF TO BE SO EXCHANGED, BY MEANS OF AN APPROPRIATE
ADJUSTMENT MADE ON THE RECORDS OF THE TRUSTEE.  UPON ANY SUCH SURRENDER OR
ADJUSTMENT, THE TRUSTEE SHALL AUTHENTICATE AND MAKE AVAILABLE FOR DELIVERY THE
NOTE ISSUABLE ON SUCH EXCHANGE TO OR UPON THE WRITTEN ORDER OF THE DEPOSITARY OR
AN AUTHORIZED REPRESENTATIVE THEREOF.

(IV)          IN THE EVENT OF THE OCCURRENCE OF ANY OF THE EVENTS SPECIFIED IN
CLAUSE (II) ABOVE, THE ISSUER WILL PROMPTLY MAKE AVAILABLE TO THE TRUSTEE A
REASONABLE SUPPLY OF CERTIFICATED NOTES IN DEFINITIVE, FULLY REGISTERED FORM,
WITHOUT INTEREST COUPONS.

(V)           NEITHER ANY MEMBERS OF, OR PARTICIPANTS IN, THE DEPOSITARY (“AGENT
MEMBERS”) NOR ANY OTHER PERSONS ON WHOSE BEHALF AGENT MEMBERS MAY ACT SHALL HAVE
ANY RIGHTS UNDER THIS INDENTURE WITH RESPECT TO ANY GLOBAL NOTE REGISTERED IN
THE NAME OF THE DEPOSITARY OR ANY NOMINEE THEREOF, AND THE DEPOSITARY OR SUCH
NOMINEE, AS THE CASE MAY BE, MAY BE TREATED BY THE ISSUER, THE TRUSTEE AND ANY
AGENT OF THE ISSUER OR THE TRUSTEE AS THE ABSOLUTE OWNER AND HOLDER OF SUCH
GLOBAL NOTE FOR ALL PURPOSES WHATSOEVER.  NOTWITHSTANDING THE FOREGOING, NOTHING
HEREIN SHALL PREVENT THE ISSUER, THE TRUSTEE OR ANY AGENT OF THE ISSUER OR THE
TRUSTEE FROM GIVING EFFECT TO ANY WRITTEN CERTIFICATION, PROXY OR OTHER
AUTHORIZATION FURNISHED BY THE DEPOSITARY OR SUCH NOMINEE, AS THE CASE MAY BE,
OR IMPAIR, AS BETWEEN THE DEPOSITARY, ITS AGENT MEMBERS AND ANY OTHER PERSON ON
WHOSE BEHALF AN AGENT MEMBER MAY ACT, THE OPERATION OF CUSTOMARY PRACTICES OF
SUCH PERSONS GOVERNING THE EXERCISE OF THE RIGHTS OF A HOLDER OF ANY NOTE.

(VI)          AT SUCH TIME AS ALL INTERESTS IN A GLOBAL NOTE HAVE BEEN REDEEMED,
REPURCHASED, CONVERTED OR EXCHANGED FOR NOTES IN CERTIFICATED FORM, SUCH GLOBAL
NOTE SHALL, UPON RECEIPT THEREOF, BE CANCELED BY THE TRUSTEE IN ACCORDANCE WITH
STANDING PROCEDURES AND INSTRUCTIONS EXISTING BETWEEN THE DEPOSITARY AND THE
CUSTODIAN.  AT ANY TIME PRIOR TO SUCH CANCELLATION, IF ANY INTEREST IN A GLOBAL
NOTE IS REDEEMED, REPURCHASED, CONVERTED OR EXCHANGED FOR NOTES IN CERTIFICATED
FORM, THE PRINCIPAL AMOUNT OF SUCH GLOBAL NOTE SHALL, IN ACCORDANCE WITH THE
STANDING PROCEDURES AND INSTRUCTIONS EXISTING BETWEEN THE DEPOSITARY AND THE
CUSTODIAN, BE APPROPRIATELY REDUCED, AND AN ENDORSEMENT SHALL BE MADE ON SUCH
GLOBAL NOTE, BY THE TRUSTEE OR THE CUSTODIAN, AT THE DIRECTION OF THE TRUSTEE,
TO REFLECT SUCH REDUCTION.

(C)           EVERY NOTE (AND ALL SECURITIES ISSUED IN EXCHANGE THEREFOR OR IN
SUBSTITUTION THEREOF) THAT BEARS OR IS REQUIRED UNDER THIS SECTION 2.05(C) TO
BEAR THE LEGEND SET FORTH IN THIS SECTION 2.05(C) (TOGETHER WITH ANY COMMON
STOCK ISSUED UPON CONVERSION OF THE NOTES, COLLECTIVELY, THE “RESTRICTED
SECURITIES”) SHALL BE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH

13

--------------------------------------------------------------------------------

IN THIS SECTION 2.05(C) (INCLUDING THOSE SET FORTH IN THE LEGEND BELOW) UNLESS
SUCH RESTRICTIONS ON TRANSFER SHALL BE WAIVED BY WRITTEN CONSENT OF THE ISSUER,
AND THE HOLDER OF EACH SUCH RESTRICTED SECURITY, BY SUCH NOTEHOLDER’S ACCEPTANCE
THEREOF, AGREES TO BE BOUND BY ALL SUCH RESTRICTIONS ON TRANSFER.  AS USED IN
THIS SECTION 2.05(C), THE TERM “TRANSFER” MEANS ANY SALE, PLEDGE, LOAN, TRANSFER
OR OTHER DISPOSITION WHATSOEVER OF ANY RESTRICTED SECURITY OR ANY INTEREST
THEREIN.

Until the expiration of the holding period applicable to sales of Restricted
Securities under Rule 144(k) under the Securities Act (or any successor
provision), any certificate evidencing a Restricted Security shall bear a legend
in substantially the following form, unless such Restricted Security has been
sold pursuant to a registration statement that has been declared effective under
the Securities Act (and which continues to be effective at the time of such
transfer) or sold pursuant to Rule 144 under the Securities Act or any similar
provision then in force, or unless otherwise agreed by the Issuer in writing,
with written notice thereof to the Trustee:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE
OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
ACQUISITION HEREOF, THE HOLDER:

(1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE
144A UNDER THE SECURITIES ACT), IS AWARE THAT THE TRANSFER TO IT IS BEING MADE
IN RELIANCE ON RULE 144A UNDER THE SECURITIES ACT AND IS ACQUIRING THIS SECURITY
IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT;

(2) AGREES THAT IT WILL NOT, WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL
ISSUE DATE OF THIS SECURITY AND THE LAST DATE ON WHICH UNITED DOMINION REALTY
TRUST, INC. OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, RESELL OR
OTHERWISE TRANSFER THIS SECURITY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF
SUCH SECURITY EXCEPT (A) TO UNITED DOMINION REALTY TRUST, INC. OR ANY OF ITS
SUBSIDIARIES, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE
144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION
PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), OR (D) PURSUANT TO
A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES
ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH RESALE OR TRANSFER;
AND

(3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS
TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE) A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY
TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE
DATE OF THIS SECURITY AND THE LAST DATE ON WHICH UNITED DOMINION REALTY TRUST,
INC. OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, THE HOLDER MUST

14

--------------------------------------------------------------------------------

CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER
OF SUCH TRANSFER AND SUBMIT THIS SECURITY TO THE TRUSTEE (OR ANY SUCCESSOR
TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C)
ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE (OR ANY
SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
INFORMATION AS UNITED DOMINION REALTY TRUST, INC. OR THE TRUSTEE MAY REASONABLY
REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF
THIS SECURITY PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE OR THE EXPIRATION OF TWO
YEARS FROM THE LATER OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND THE LAST
DATE ON WHICH UNITED DOMINION REALTY TRUST, INC. OR AN AFFILIATE THEREOF WAS THE
OWNER OF THIS SECURITY.

Any Notes that are Restricted Securities and as to which such restrictions on
transfer shall have expired in accordance with their terms or as to conditions
for removal of the foregoing legend set forth therein have been satisfied may,
upon surrender of such Note for exchange to the Note Registrar in accordance
with the provisions of this Section 2.05, be exchanged for a new Note or Notes,
of like tenor and aggregate principal amount, which shall not bear the
restrictive legend required by this Section 2.05(c).  If such Restricted
Security surrendered for exchange is represented by a Global Note bearing the
legend set forth in this Section 2.05(c), the principal amount of the legended
Global Note shall be reduced by the appropriate principal amount and the
principal amount of a Global Note without the legend set forth in this Section
2.05(c) shall be increased by an equal principal amount.  If a Global Note
without the legend set forth in this Section 2.05(c) is not then outstanding,
the Issuer shall execute and the Trustee shall authenticate and deliver an
unlegended Global Note to the Depositary.

In the event Rule 144(k) under the Securities Act (or any successor provision)
is amended to shorten the two-year period under Rule 144(k), then, the
references in the restrictive legends set forth above to “TWO YEARS,” and in the
corresponding transfer restrictions described above, and in the Notes and the
shares of Common Stock will be deemed to refer to such shorter period, from and
after receipt by the Trustee of an Officers’ Certificate and an Opinion of
Counsel to that effect.  As soon as reasonably practicable after the Issuer
knows of the effectiveness of any such amendment to shorten the two-year period
under Rule 144(k), unless such changes would otherwise be prohibited by, or
would cause a violation of, the federal securities laws applicable at the time,
the Issuer will provide to the Trustee an Officers’ Certificate and an Opinion
of Counsel as to the effectiveness of such amendment and the effectiveness of
such change to the restrictive legends and transfer restrictions.

(D)           THE ISSUER OR ANY OF ITS AFFILIATES MAY, TO THE EXTENT PERMITTED
BY APPLICABLE LAW, AT ANY TIME PURCHASE NOTES IN THE OPEN MARKET, BY TENDER AT
ANY PRICE OR BY PRIVATE AGREEMENT.  ANY NOTE PURCHASED BY THE ISSUER OR ANY OF
ITS AFFILIATES (A) AFTER THE DATE THAT IS TWO YEARS FROM THE LATEST ISSUANCE OF
THE NOTES MAY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, BE REISSUED OR SOLD OR
MAY BE SURRENDERED TO THE TRUSTEE FOR CANCELLATION OR (B) ON OR PRIOR TO THE
DATE IN CLAUSE

15

--------------------------------------------------------------------------------

(A), SHALL BE SURRENDERED TO THE TRUSTEE FOR CANCELLATION.  ANY NOTES
SURRENDERED FOR CANCELLATION MAY NOT BE REISSUED OR RESOLD AND SHALL BE CANCELED
PROMPTLY.

(E)           THE TRUSTEE SHALL HAVE NO RESPONSIBILITY OR OBLIGATION TO ANY
AGENT MEMBERS OR ANY OTHER PERSON WITH RESPECT TO THE ACCURACY OF THE BOOKS OR
RECORDS, OR THE ACTS OR OMISSIONS, OF THE DEPOSITARY OR ITS NOMINEE OR OF ANY
PARTICIPANT OR MEMBER THEREOF, WITH RESPECT TO ANY OWNERSHIP INTEREST IN THE
NOTES OR WITH RESPECT TO THE DELIVERY TO ANY AGENT MEMBER OR OTHER PERSON (OTHER
THAN THE DEPOSITARY) OF ANY NOTICE (INCLUDING ANY NOTICE OF REDEMPTION) OR THE
PAYMENT OF ANY AMOUNT, UNDER OR WITH RESPECT TO SUCH NOTES.  ALL NOTICES AND
COMMUNICATIONS TO BE GIVEN TO THE NOTEHOLDERS AND ALL PAYMENTS TO BE MADE TO
NOTEHOLDERS UNDER THE NOTES SHALL BE GIVEN OR MADE ONLY TO OR UPON THE ORDER OF
THE REGISTERED NOTEHOLDERS (WHICH SHALL BE THE DEPOSITARY OR ITS NOMINEE IN THE
CASE OF A GLOBAL NOTE).  THE RIGHTS OF BENEFICIAL OWNERS IN ANY GLOBAL NOTE
SHALL BE EXERCISED ONLY THROUGH THE DEPOSITARY SUBJECT TO THE CUSTOMARY
PROCEDURES OF THE DEPOSITORY.  THE TRUSTEE MAY RELY AND SHALL BE FULLY PROTECTED
IN RELYING UPON INFORMATION FURNISHED BY THE DEPOSITARY WITH RESPECT TO ITS
AGENT MEMBERS.

The Trustee shall have no obligation or duty to monitor, determine or inquire as
to compliance with any restrictions on transfer imposed under this Indenture or
under applicable law with respect to any transfer of any interest in any Note
(including any transfers between or among Agent Members in any Global Indenture)
other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by, the terms of this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

SECTION 2.06.  MUTILATED, DESTROYED, LOST OR STOLEN NOTES.  IN CASE ANY NOTE
SHALL BECOME MUTILATED OR BE DESTROYED, LOST OR STOLEN, THE ISSUER IN ITS
DISCRETION MAY EXECUTE, AND UPON ITS WRITTEN REQUEST THE TRUSTEE OR AN
AUTHENTICATING AGENT APPOINTED BY THE TRUSTEE SHALL AUTHENTICATE AND MAKE
AVAILABLE FOR DELIVERY, A NEW NOTE, BEARING A NUMBER NOT CONTEMPORANEOUSLY
OUTSTANDING, IN EXCHANGE AND SUBSTITUTION FOR THE MUTILATED NOTE, OR IN LIEU OF
AND IN SUBSTITUTION FOR THE NOTE SO DESTROYED, LOST OR STOLEN.  IN EVERY CASE,
THE APPLICANT FOR A SUBSTITUTED NOTE SHALL FURNISH TO THE ISSUER, TO THE TRUSTEE
AND, IF APPLICABLE, TO SUCH AUTHENTICATING AGENT SUCH SECURITY OR INDEMNITY AS
MAY BE REQUIRED BY THEM TO SAVE EACH OF THEM HARMLESS FOR ANY LOSS, LIABILITY,
COST OR EXPENSE CAUSED BY OR CONNECTED WITH SUCH SUBSTITUTION, AND, IN EVERY
CASE OF DESTRUCTION, LOSS OR THEFT, THE APPLICANT SHALL ALSO FURNISH TO THE
ISSUER, TO THE TRUSTEE AND, IF APPLICABLE, TO SUCH AUTHENTICATING AGENT EVIDENCE
TO THEIR SATISFACTION OF THE DESTRUCTION, LOSS OR THEFT OF SUCH NOTE AND OF THE
OWNERSHIP THEREOF.

Following receipt by the Trustee or such authenticating agent, as the case may
be, of satisfactory security or indemnity and evidence, as described in the
preceding paragraph, the Trustee or such authenticating agent may authenticate
any such substituted Note and make available for delivery such Note. Upon the
issuance of any substituted Note, the Issuer may require the payment by the
holder of a sum sufficient to cover any tax, assessment or other governmental
charge that may be imposed in relation thereto and any other expenses connected
therewith.  In case any Note which has matured or is about to mature or has been
called for redemption or has been properly tendered for repurchase on a Change
in Control Repurchase Date (and not withdrawn), as the case may be, or is to be
converted pursuant to this Indenture, shall become mutilated or be destroyed,
lost or stolen, the Issuer may, instead of issuing a

16

--------------------------------------------------------------------------------

substitute Note, pay or authorize the payment of or authorize the conversion of
the same (without surrender thereof except in the case of a mutilated Note), as
the case may be, if the applicant for such payment or conversion shall furnish
to the Issuer, to the Trustee and, if applicable, to such authenticating agent
such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or in connection
with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Issuer, the Trustee and, if applicable, any
Paying Agent or Conversion Agent evidence to their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by
virtue of the fact that any Note is destroyed, lost or stolen shall constitute
an additional contractual obligation of the Issuer, whether or not the
destroyed, lost or stolen Note shall be found at any time, and shall be entitled
to all the benefits of (but shall be subject to all the limitations set forth
in) this Indenture equally and proportionately with any and all other Notes duly
issued hereunder.  To the extent permitted by law, all Notes shall be held and
owned upon the express condition that the foregoing provisions are exclusive
with respect to the replacement or payment or exchange or redemption or
repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any
and all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment or
exchange or redemption or repurchase of negotiable instruments or other
securities without their surrender.

SECTION 2.07.  TEMPORARY NOTES.  PENDING THE PREPARATION OF NOTES IN
CERTIFICATED FORM, THE ISSUER MAY EXECUTE AND THE TRUSTEE OR AN AUTHENTICATING
AGENT APPOINTED BY THE TRUSTEE SHALL, UPON THE WRITTEN REQUEST OF THE ISSUER,
AUTHENTICATE AND DELIVER TEMPORARY NOTES (PRINTED OR LITHOGRAPHED).  TEMPORARY
NOTES SHALL BE ISSUABLE IN ANY AUTHORIZED DENOMINATION, AND SUBSTANTIALLY IN THE
FORM OF THE NOTES IN CERTIFICATED FORM, BUT WITH SUCH OMISSIONS, INSERTIONS AND
VARIATIONS AS MAY BE APPROPRIATE FOR TEMPORARY NOTES, ALL AS MAY BE DETERMINED
BY THE ISSUER.  EVERY SUCH TEMPORARY NOTE SHALL BE EXECUTED BY THE ISSUER AND
AUTHENTICATED BY THE TRUSTEE OR SUCH AUTHENTICATING AGENT UPON THE SAME
CONDITIONS AND IN SUBSTANTIALLY THE SAME MANNER, AND WITH THE SAME EFFECT, AS
THE NOTES IN CERTIFICATED FORM. WITHOUT UNREASONABLE DELAY, THE ISSUER WILL
EXECUTE AND DELIVER TO THE TRUSTEE OR SUCH AUTHENTICATING AGENT NOTES IN
CERTIFICATED FORM AND THEREUPON ANY OR ALL TEMPORARY NOTES MAY BE SURRENDERED IN
EXCHANGE THEREFOR, AT EACH OFFICE OR AGENCY MAINTAINED BY THE ISSUER PURSUANT TO
SECTION 4.02 AND THE TRUSTEE OR SUCH AUTHENTICATING AGENT SHALL AUTHENTICATE AND
MAKE AVAILABLE FOR DELIVERY IN EXCHANGE FOR SUCH TEMPORARY NOTES AN EQUAL
AGGREGATE PRINCIPAL AMOUNT OF NOTES IN CERTIFICATED FORM.  SUCH EXCHANGE SHALL
BE MADE BY THE ISSUER AT ITS OWN EXPENSE AND WITHOUT ANY CHARGE THEREFOR.  UNTIL
SO EXCHANGED, THE TEMPORARY NOTES SHALL IN ALL RESPECTS BE ENTITLED TO THE SAME
BENEFITS AND SUBJECT TO THE SAME LIMITATIONS UNDER THIS INDENTURE AS NOTES IN
CERTIFICATED FORM AUTHENTICATED AND DELIVERED HEREUNDER.

SECTION 2.08.  CANCELLATION OF NOTES.  ALL NOTES SURRENDERED FOR THE PURPOSE OF
PAYMENT, REDEMPTION, REPURCHASE, CONVERSION, EXCHANGE OR REGISTRATION OF
TRANSFER SHALL, IF SURRENDERED TO THE ISSUER OR ANY PAYING AGENT TO WHOM NOTES
MAY BE PRESENTED FOR PAYMENT (THE “PAYING AGENT”) OR CONVERSION AGENT, WHICH
SHALL INITIALLY BE THE TRUSTEE, OR ANY NOTE REGISTRAR, BE SURRENDERED TO THE
TRUSTEE AND PROMPTLY CANCELED BY IT OR, IF SURRENDERED TO THE TRUSTEE, SHALL BE
PROMPTLY CANCELED BY IT AND NO NOTES SHALL BE ISSUED IN LIEU THEREOF EXCEPT AS
EXPRESSLY PERMITTED BY ANY OF THE PROVISIONS OF THIS INDENTURE.  THE TRUSTEE
SHALL DISPOSE OF SUCH CANCELED NOTES IN

17

--------------------------------------------------------------------------------

ACCORDANCE WITH ITS CUSTOMARY PROCEDURES.  IF THE ISSUER SHALL ACQUIRE ANY OF
THE NOTES, SUCH ACQUISITION SHALL NOT OPERATE AS A REDEMPTION, REPURCHASE OR
SATISFACTION OF THE INDEBTEDNESS REPRESENTED BY SUCH NOTES UNLESS AND UNTIL THE
SAME ARE DELIVERED TO THE TRUSTEE FOR CANCELLATION.

SECTION 2.09.  CUSIP NUMBERS.  THE ISSUER IN ISSUING THE NOTES MAY USE “CUSIP”
NUMBERS (IF THEN GENERALLY IN USE), AND, IF SO, THE TRUSTEE SHALL USE “CUSIP”
NUMBERS IN NOTICES OF REDEMPTION AS A CONVENIENCE TO NOTEHOLDERS; PROVIDED THAT
ANY SUCH NOTICE MAY STATE THAT NO REPRESENTATION IS MADE AS TO THE CORRECTNESS
OF SUCH NUMBERS EITHER AS PRINTED ON THE NOTES OR AS CONTAINED IN ANY NOTICE OF
A REDEMPTION AND THAT RELIANCE MAY BE PLACED ONLY ON THE OTHER IDENTIFICATION
NUMBERS PRINTED ON THE NOTES, AND ANY SUCH REDEMPTION SHALL NOT BE AFFECTED BY
ANY DEFECT IN OR OMISSION OF SUCH NUMBERS.  THE ISSUER WILL PROMPTLY NOTIFY THE
TRUSTEE OF ANY CHANGE IN THE “CUSIP” NUMBERS.

ARTICLE 3
REDEMPTION AND REPURCHASE OF NOTES

SECTION 3.01.  OPTIONAL REDEMPTION OF NOTES.  THE ISSUER SHALL HAVE THE RIGHT TO
REDEEM THE NOTES ON THE TERMS SET FORTH IN THIS SECTION 3.01 IN ORDER TO
PRESERVE ITS STATUS AS A REAL ESTATE INVESTMENT TRUST.  IF THE ISSUER DETERMINES
IT IS NECESSARY TO REDEEM THE NOTES IN ORDER TO PRESERVE ITS STATUS AS A REAL
ESTATE INVESTMENT TRUST, THE ISSUER MAY, UPON THE NOTICE SET FORTH IN SECTION
3.02, REDEEM THE NOTES FOR CASH, IN WHOLE OR IN PART, AT A REDEMPTION PRICE
EQUAL TO 100% OF THE PRINCIPAL AMOUNT OF THE NOTES TO BE REDEEMED PLUS UNPAID
INTEREST, IF ANY, ACCRUED THEREON TO THE REDEMPTION DATE; PROVIDED THAT, IN
CONNECTION WITH ANY SUCH REDEMPTION, THE ISSUER SHALL PROVIDE THE TRUSTEE WITH
AN OFFICERS’ CERTIFICATE EVIDENCING THAT THE BOARD OF DIRECTORS HAS, IN GOOD
FAITH, MADE THE DETERMINATION THAT IT IS NECESSARY TO REDEEM THE NOTES IN ORDER
TO PRESERVE THE ISSUER’S STATUS AS A REAL ESTATE INVESTMENT TRUST.

Other than as set forth in the preceding paragraph, the Notes shall not be
subject to redemption at the option of the Issuer prior the Stated Maturity
thereof.

SECTION 3.02.  NOTICE OF OPTIONAL REDEMPTION; SELECTION OF NOTES.  IN CASE THE
ISSUER SHALL DESIRE TO EXERCISE THE RIGHT TO REDEEM ALL OR, AS THE CASE MAY BE,
ANY PART OF THE NOTES PURSUANT TO SECTION 3.01, IT SHALL FIX A DATE FOR
REDEMPTION AND IT OR, AT ITS WRITTEN REQUEST RECEIVED BY THE TRUSTEE NOT FEWER
THAN FIVE (5) BUSINESS DAYS PRIOR (OR SUCH SHORTER PERIOD OF TIME AS MAY BE
ACCEPTABLE TO THE TRUSTEE) TO THE DATE THE NOTICE OF REDEMPTION IS TO BE MAILED,
THE TRUSTEE IN THE NAME OF AND AT THE EXPENSE OF THE ISSUER, SHALL MAIL OR CAUSE
TO BE MAILED A NOTICE OF SUCH REDEMPTION NOT FEWER THAN THIRTY (30) CALENDAR
DAYS NOR MORE THAN SIXTY (60) CALENDAR DAYS PRIOR TO THE REDEMPTION DATE TO EACH
HOLDER OF NOTES SO TO BE REDEEMED IN WHOLE OR IN PART AT ITS LAST ADDRESS AS THE
SAME APPEARS ON THE NOTE REGISTER; PROVIDED THAT IF THE ISSUER MAKES SUCH
REQUEST OF THE TRUSTEE, THE TEXT OF THE NOTICE SHALL BE PREPARED BY THE ISSUER. 
SUCH MAILING SHALL BE BY FIRST CLASS MAIL.  THE NOTICE, IF MAILED IN THE MANNER
HEREIN PROVIDED, SHALL BE CONCLUSIVELY PRESUMED TO HAVE BEEN DULY GIVEN, WHETHER
OR NOT THE HOLDER RECEIVES SUCH NOTICE.  IN ANY CASE, FAILURE TO GIVE SUCH
NOTICE BY MAIL OR ANY DEFECT IN THE NOTICE TO THE HOLDER OF ANY NOTE DESIGNATED
FOR REDEMPTION AS A WHOLE OR IN PART SHALL NOT AFFECT THE VALIDITY OF THE
PROCEEDINGS FOR THE REDEMPTION OF ANY OTHER NOTE.  CONCURRENTLY WITH THE MAILING
OF ANY SUCH NOTICE OF REDEMPTION, THE ISSUER SHALL ISSUE A PRESS RELEASE
ANNOUNCING SUCH REDEMPTION, THE FORM AND CONTENT OF WHICH PRESS RELEASE SHALL BE
DETERMINED BY THE ISSUER IN ITS SOLE DISCRETION.  THE FAILURE

18

--------------------------------------------------------------------------------

TO ISSUE ANY SUCH PRESS RELEASE OR ANY DEFECT THEREIN SHALL NOT AFFECT THE
VALIDITY OF THE REDEMPTION NOTICE OR ANY OF THE PROCEEDINGS FOR THE REDEMPTION
OF ANY NOTE CALLED FOR REDEMPTION.

Each such notice of redemption shall specify: (i) the aggregate principal amount
of Notes to be redeemed, (ii) the CUSIP number or numbers of the Notes being
redeemed, (iii) the date fixed for redemption (which shall be a Business Day),
(iv) the redemption price at which Notes are to be redeemed, (v) the place or
places of payment and that payment will be made upon presentation and surrender
of such Notes, (iv) that interest accrued and unpaid to the date fixed for
redemption will be paid as specified in said notice, and that on and after said
date interest thereon or on the portion thereof to be redeemed will cease to
accrue, (vii) that the holder has a right to convert the Notes called for
redemption, (viii) the Conversion Rate on the date of such notice and (ix) the
time and date on which the right to convert such Notes or portions thereof
pursuant to this Indenture will expire.  If fewer than all the Notes are to be
redeemed, the notice of redemption shall identify the Notes to be redeemed
(including CUSIP numbers, if any).  In case any Note is to be redeemed in part
only, the notice of redemption shall state the portion of the principal amount
thereof to be redeemed and shall state that, on and after the Redemption Date,
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion thereof will be issued.

Whenever any Notes are to be redeemed, the Issuer shall give the Trustee written
notice of the Redemption Date, together with an Officers’ Certificate as to the
aggregate principal amount of Notes to be redeemed, not fewer than thirty (30)
calendar days (or such shorter period of time as may be acceptable to the
Trustee) prior to the Redemption Date.

On or prior to the Redemption Date specified in the notice of redemption given
as provided in this Section 3.02, the Issuer shall deposit with the Paying Agent
(or, if the Issuer is acting as its own Paying Agent, set aside, segregate and
hold in trust as provided in Section 4.04) an amount of money in immediately
available funds sufficient to redeem on the Redemption Date all the Notes (or
portions thereof) so called for redemption (other than those theretofore
surrendered for exchange) at the appropriate redemption price, together with
accrued interest to the Redemption Date; provided that if such payment is made
on the Redemption Date, it must be received by the Paying Agent, by 11:00 a.m.,
New York City time, on such date.  The Issuer shall be entitled to retain any
interest, yield or gain on amounts deposited with the Paying Agent pursuant to
this Section 3.02 in excess of amounts required hereunder to pay the redemption
price and accrued interest to the Redemption Date.  If any Note called for
redemption is converted pursuant hereto prior to such Redemption Date, any money
deposited with the Paying Agent or so segregated and held in trust for the
redemption of such Note shall be paid to the Issuer or, if then held by the
Issuer, shall be discharged from such trust.

If less than all of the outstanding Notes are to be redeemed, the Trustee shall
select the Notes or portions thereof of the Global Note or the Notes in
certificated form to be redeemed (in principal amounts of $1,000 or multiples
thereof) on a pro rata basis or by another method the Trustee deems fair and
appropriate.  If any Note selected for redemption in part is submitted for
conversion in part after such selection, the portion of such Note submitted for
conversion shall be deemed (so far as may be possible) to be the portion to be
selected for redemption.  The Notes (or portions thereof) so selected for
redemption shall be deemed duly selected for redemption for

19

--------------------------------------------------------------------------------

all purposes hereof, notwithstanding that any such Note is submitted for
conversion in part before the mailing of the notice of redemption.

Upon any redemption of less than all of the outstanding Notes, the Issuer and
the Trustee may (but need not), solely for purposes of determining the pro rata
allocation among such Notes that are outstanding at the time of redemption,
treat as outstanding any Notes surrendered for conversion during the period in
which Notes are selected for redemption.

SECTION 3.03.  PAYMENT OF NOTES CALLED FOR REDEMPTION BY THE ISSUER.  IF NOTICE
OF REDEMPTION HAS BEEN GIVEN AS PROVIDED IN SECTION 3.02, THE NOTES OR PORTION
OF NOTES WITH RESPECT TO WHICH SUCH NOTICE HAS BEEN GIVEN SHALL, UNLESS
CONVERTED PURSUANT TO THE TERMS HEREOF, BECOME DUE AND PAYABLE ON THE DATE FIXED
FOR REDEMPTION AT THE PLACE OR PLACES STATED IN SUCH NOTICE AT THE REDEMPTION
PRICE, PLUS INTEREST ACCRUED TO THE REDEMPTION DATE, AND UNLESS THE ISSUER SHALL
DEFAULT IN THE PAYMENT OF THE AMOUNTS OWING ON THE NOTES UPON SUCH REDEMPTION,
INTEREST ON THE NOTES OR PORTION OF NOTES SO CALLED FOR REDEMPTION SHALL CEASE
TO ACCRUE ON AND AFTER SUCH DATE AND, EXCEPT AS PROVIDED IN SECTION 7.05 AND
SECTION 11.02, THE NOTES SHALL CEASE TO BE ENTITLED TO ANY BENEFIT OR SECURITY
UNDER THIS INDENTURE, AND THE HOLDERS THEREOF SHALL HAVE NO RIGHT IN RESPECT OF
SUCH NOTES EXCEPT THE RIGHT TO RECEIVE THE REDEMPTION PRICE THEREOF PLUS ACCRUED
AND UNPAID INTEREST TO THE REDEMPTION DATE.  ON PRESENTATION AND SURRENDER OF
SUCH NOTES AT A PLACE OF PAYMENT IN SAID NOTICE SPECIFIED, THE SAID NOTES OR THE
SPECIFIED PORTIONS THEREOF SHALL BE PAID AND REDEEMED BY THE ISSUER AT THE
REDEMPTION PRICE, TOGETHER WITH INTEREST ACCRUED THEREON TO THE REDEMPTION DATE.

Upon presentation of any Note redeemed in part only, the Issuer shall execute
and the Trustee shall authenticate and make available for delivery to the holder
thereof, at the expense of the Issuer, a new Note or Notes, of authorized
denominations, in principal amount equal to the unredeemed portion of the Notes
so presented.

Notes and portions of Notes that are to be redeemed pursuant to this Article 3
shall be convertible by the Holder thereof until 5:00 p.m., New York City time,
on the second Business Day immediately preceding the Redemption Date, unless the
Issuer shall fail to pay the redemption price.

SECTION 3.04.  SINKING FUND.  THERE SHALL BE NO SINKING FUND PROVIDED FOR THE
NOTES.

SECTION 3.05.  REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE IN CONTROL.

(A)           IF THERE SHALL OCCUR A CHANGE IN CONTROL AT ANY TIME PRIOR TO THE
STATED MATURITY OF THE NOTES, THEN EACH NOTEHOLDER SHALL HAVE THE RIGHT TO
REQUIRE THE ISSUER TO REPURCHASE ITS NOTES FOR CASH, IN WHOLE OR IN PART (IN
PRINCIPAL AMOUNTS OF $1,000 AND INTEGRAL MULTIPLES THEREOF), ON A DATE (THE
“CHANGE IN CONTROL REPURCHASE DATE”) SPECIFIED BY THE ISSUER (WHICH DATE SHALL
BE NOT EARLIER THAN FIFTEEN (15) DAYS AND NOT MORE THAN THIRTY (30) DAYS AFTER
THE ISSUER REPURCHASE NOTICE DATE RELATED TO SUCH CHANGE IN CONTROL) AT A
PURCHASE PRICE EQUAL TO 100% OF THE PRINCIPAL AMOUNT OF THE NOTES BEING
REPURCHASED, PLUS ACCRUED AND UNPAID INTEREST TO THE CHANGE IN CONTROL
REPURCHASE DATE (SUCH AMOUNT, THE “CHANGE IN CONTROL PURCHASE PRICE”).

(B)           WITHIN 20 DAYS AFTER THE OCCURRENCE OF A CHANGE IN CONTROL, THE

THE CHANGE IN CONTROL (AND TO

BENEFICIAL OWNERS AS REQUIRED BY APPLICABLE LAW) AN ISSUER REPURCHASE NOTICE AS
SET FORTH IN SECTION 3.07 WITH RESPECT TO SUCH CHANGE IN CONTROL.  THE ISSUER
SHALL ALSO DELIVER A COPY OF THE ISSUER REPURCHASE NOTICE TO THE TRUSTEE AND THE
PAYING AGENT AT SUCH TIME AS IT IS MAILED TO NOTEHOLDERS.  IN ADDITION TO THE
MAILING OF SUCH ISSUER REPURCHASE NOTICE, THE ISSUER SHALL DISSEMINATE A PRESS
RELEASE THROUGH DOW JONES & COMPANY, INC., BLOOMBERG BUSINESS NEWS OR A
SUBSTANTIALLY SIMILAR FINANCIAL NEWS ORGANIZATION ANNOUNCING THE OCCURRENCE OF
SUCH CHANGE IN CONTROL AND PUBLISH SUCH INFORMATION IN A NEWSPAPER OF GENERAL
CIRCULATION IN THE CITY OF NEW YORK OR ON THE ISSUER’S WEB SITE, OR THROUGH SUCH
OTHER PUBLIC MEDIUM AS THE ISSUER SHALL DEEM APPROPRIATE AT SUCH TIME.  THE
FAILURE TO ISSUE ANY SUCH PRESS RELEASE OR ANY DEFECT THEREIN SHALL NOT AFFECT
THE VALIDITY OF THE ISSUER REPURCHASE NOTICE OR ANY PROCEEDINGS FOR THE
REPURCHASE OF ANY NOTE WHICH ANY NOTEHOLDER MAY ELECT TO HAVE THE ISSUER REDEEM
AS PROVIDED IN THIS SECTION 3.05.

No failure of the Issuer to give the foregoing notices and no defect therein
shall limit the Noteholders’ repurchase rights or affect the validity of the
proceedings for the repurchase of the Notes pursuant to this Section 3.05.

(C)           IN ORDER TO EXERCISE ITS REPURCHASE RIGHT, THE HOLDER MUST DELIVER
TO THE PAYING AGENT, PRIOR TO THE CLOSE OF BUSINESS ON THE THIRD BUSINESS DAY
PRIOR TO THE CHANGE IN CONTROL REPURCHASE DATE, A WRITTEN NOTICE OF REPURCHASE
(THE “REPURCHASE NOTICE”).  SUCH REPURCHASE NOTICE SHALL STATE:  (A) THE
CERTIFICATE NUMBER (IF THE NOTE IS IN CERTIFICATED FORM) OF THE NOTE WHICH THE
HOLDER WILL DELIVER TO BE REPURCHASED, (B) THE PORTION OF THE PRINCIPAL AMOUNT
OF THE NOTE WHICH THE HOLDER WILL DELIVER TO BE REPURCHASED, IN MULTIPLES OF
$1,000, PROVIDED THAT THE REMAINING PRINCIPAL AMOUNT OF NOTES IS IN AN
AUTHORIZED DENOMINATION AND (C) THAT SUCH NOTE SHALL BE REPURCHASED PURSUANT TO
THE TERMS AND CONDITIONS SPECIFIED IN THE NOTE AND IN THIS INDENTURE.  ANY
REPURCHASE NOTICE PROVIDED IN RESPECT OF A BENEFICIAL INTEREST IN A GLOBAL NOTE
SHALL BE REQUIRED TO COMPLY WITH THE APPLICABLE PROCEDURES OF THE DEPOSITARY.

(D)           THE ISSUER, IF SO REQUESTED, SHALL REPURCHASE FROM THE HOLDER
THEREOF, PURSUANT TO THIS SECTION 3.05, A PORTION OF A NOTE, IF THE PRINCIPAL
AMOUNT OF SUCH PORTION IS $1,000 OR A WHOLE MULTIPLE OF $1,000.  PROVISIONS OF
THIS INDENTURE THAT APPLY TO THE REPURCHASE OF ALL OF A NOTE ALSO APPLY TO THE
REPURCHASE OF SUCH PORTION OF SUCH NOTE.

(E)           NOTWITHSTANDING THE FOREGOING, NO NOTES MAY BE REPURCHASED BY THE
ISSUER PURSUANT TO THIS SECTION 3.05 IF THERE HAS OCCURRED AND IS CONTINUING AN
EVENT OF DEFAULT WITH RESPECT TO THE NOTES (OTHER THAN A DEFAULT IN THE PAYMENT
OF THE CHANGE IN CONTROL PURCHASE PRICE FOR THE NOTES TO BE REPURCHASED).

(F)            THE PAYING AGENT SHALL PROMPTLY NOTIFY THE ISSUER OF THE RECEIPT
BY IT OF ANY REPURCHASE NOTICE OR WRITTEN NOTICE OF WITHDRAWAL THEREOF.  ALL
QUESTIONS AS TO THE VALIDITY, ELIGIBILITY (INCLUDING TIME OF RECEIPT) AND
ACCEPTANCE OF ANY NOTE FOR REPURCHASE SHALL BE DETERMINED BY THE ISSUER, WHOSE
DETERMINATION SHALL BE FINAL AND BINDING ABSENT MANIFEST ERROR.

(G)           PAYMENT OF THE CHANGE IN CONTROL PURCHASE PRICE FOR A NOTE FOR
WHICH A REPURCHASE NOTICE HAS BEEN DELIVERED AND NOT WITHDRAWN IS CONDITIONED
UPON BOOK-ENTRY TRANSFER OR DELIVERY OF THE NOTES, TOGETHER WITH NECESSARY
ENDORSEMENTS, TO THE PAYING AGENT.  SUCH CHANGE IN CONTROL PURCHASE PRICE SHALL

the Trustee for its expenses, disbursements and advances pursuant to Section

official shall have been appointed for or taken possession of the Issuer or such
other obligor, the property of the Issuer or such other obligor, or in the case

receive any monies or other property payable or deliverable on any such claims,
and to distribute the same after the deduction of any amounts due the Trustee
under Section 7.06, and to take any other action with respect to such claims,
including participating as a member of any official committee of creditors, as
it reasonably deems necessary or advisable, unless prohibited by law or
applicable regulations, and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized
by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including counsel fees and
expenses incurred by it up to the date of such distribution.  To the extent that
such payment of reasonable compensation, expenses, advances and disbursements
out of the estate in any such proceedings shall be denied for any reason,
payment of the same shall be secured by a lien on, and shall be paid out of, any
and all distributions, dividends, monies, securities and other property which
the holders of the Notes may be entitled to receive in such proceedings, whether

the Notes, or the production thereof at any trial or other proceeding relative
thereto, and any such suit or 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,

such proceedings.

THE NOTEHOLDERS

SECTION 8.01.  ACTION BY NOTEHOLDERS.  WHENEVER IN THIS INDENTURE IT IS PROVIDED
THAT THE HOLDERS OF A SPECIFIED PERCENTAGE IN AGGREGATE PRINCIPAL AMOUNT OF THE
NOTES MAY TAKE ANY ACTION (INCLUDING THE MAKING OF ANY DEMAND OR REQUEST, THE
GIVING OF ANY NOTICE, CONSENT OR WAIVER OR THE TAKING OF ANY OTHER ACTION), THE
FACT THAT AT THE TIME OF TAKING ANY SUCH ACTION, THE HOLDERS OF SUCH SPECIFIED
PERCENTAGE HAVE JOINED THEREIN MAY BE EVIDENCED (A) BY ANY INSTRUMENT OR ANY
NUMBER OF INSTRUMENTS OF SIMILAR TENOR EXECUTED BY NOTEHOLDERS IN PERSON OR BY
AGENT OR PROXY APPOINTED IN WRITING, OR (B) BY THE RECORD OF THE HOLDERS OF
NOTES VOTING IN FAVOR THEREOF AT ANY MEETING OF NOTEHOLDERS, OR (C) BY A
COMBINATION OF SUCH INSTRUMENT OR INSTRUMENTS AND ANY SUCH RECORD OF SUCH A
MEETING OF NOTEHOLDERS.  WHENEVER THE ISSUER OR THE TRUSTEE SOLICITS THE TAKING
OF ANY ACTION BY THE HOLDERS OF THE NOTES, THE ISSUER OR THE TRUSTEE MAY FIX IN
ADVANCE OF SUCH SOLICITATION A DATE AS THE RECORD DATE FOR DETERMINING HOLDERS
ENTITLED TO TAKE SUCH ACTION.  THE RECORD DATE, IF ANY, SHALL BE NOT MORE THAN
FIFTEEN (15) CALENDAR DAYS PRIOR TO THE DATE OF COMMENCEMENT OF SOLICITATION OF
SUCH ACTION.

SECTION 8.02.  PROOF OF EXECUTION BY NOTEHOLDERS.  SUBJECT TO THE PROVISIONS OF
SECTIONS 7.01 AND 7.02, PROOF OF THE EXECUTION OF ANY INSTRUMENT BY A NOTEHOLDER
OR ITS AGENT OR PROXY SHALL BE SUFFICIENT IF MADE IN ACCORDANCE WITH SUCH
REASONABLE RULES AND REGULATIONS AS MAY BE PRESCRIBED BY THE TRUSTEE OR IN SUCH
MANNER AS SHALL BE SATISFACTORY TO THE TRUSTEE.  THE HOLDING OF NOTES SHALL BE
PROVED BY THE REGISTRY OF SUCH NOTES OR BY A CERTIFICATE OF THE NOTE REGISTRAR.

SECTION 8.03.  ABSOLUTE OWNERS.  THE ISSUER, THE TRUSTEE, ANY PAYING AGENT, ANY
CONVERSION AGENT AND ANY NOTE REGISTRAR MAY DEEM THE PERSON IN WHOSE NAME SUCH

NOTWITHSTANDING ANY NOTATION OF OWNERSHIP OR

42

--------------------------------------------------------------------------------

OTHER WRITING THEREON MADE BY ANY PERSON OTHER THAN THE ISSUER OR ANY NOTE
REGISTRAR) FOR THE PURPOSE OF RECEIVING PAYMENT OF OR ON ACCOUNT OF THE
PRINCIPAL OF, AND INTEREST ON, SUCH NOTE, FOR CONVERSION OF SUCH NOTE AND FOR
ALL OTHER PURPOSES; AND NEITHER THE ISSUER NOR THE TRUSTEE NOR ANY PAYING AGENT
NOR ANY CONVERSION AGENT NOR ANY NOTE REGISTRAR SHALL BE AFFECTED BY ANY NOTICE
TO THE CONTRARY.  ALL SUCH PAYMENTS SO MADE TO ANY HOLDER FOR THE TIME BEING, OR
UPON ITS ORDER, SHALL BE VALID, AND, TO THE EXTENT OF THE SUM OR SUMS SO PAID,
EFFECTUAL TO SATISFY AND DISCHARGE THE LIABILITY FOR MONIES PAYABLE UPON ANY
SUCH NOTE.

SECTION 8.04.  ISSUER-OWNED NOTES DISREGARDED.  IN DETERMINING WHETHER THE
HOLDERS OF THE REQUISITE AGGREGATE PRINCIPAL AMOUNT OF NOTES HAVE CONCURRED IN
ANY DIRECTION, CONSENT, WAIVER OR OTHER ACTION UNDER THIS INDENTURE, NOTES WHICH
ARE OWNED BY THE ISSUER OR ANY OTHER OBLIGOR ON THE NOTES OR ANY AFFILIATE OF
THE ISSUER OR ANY OTHER OBLIGOR ON THE NOTES SHALL BE DISREGARDED AND DEEMED NOT
TO BE OUTSTANDING FOR THE PURPOSE OF ANY SUCH DETERMINATION; PROVIDED THAT FOR
THE PURPOSES OF DETERMINING WHETHER THE TRUSTEE SHALL BE PROTECTED IN RELYING ON
ANY SUCH DIRECTION, CONSENT, WAIVER OR OTHER ACTION, ONLY NOTES WHICH A
RESPONSIBLE OFFICER KNOWS ARE SO OWNED SHALL BE SO DISREGARDED.  NOTES SO OWNED
WHICH HAVE BEEN PLEDGED IN GOOD FAITH MAY BE REGARDED AS OUTSTANDING FOR THE
PURPOSES OF THIS SECTION 8.04 IF THE PLEDGEE SHALL ESTABLISH TO THE SATISFACTION
OF THE TRUSTEE THE PLEDGEE’S RIGHT TO VOTE SUCH NOTES AND THAT THE PLEDGEE IS
NOT THE ISSUER, ANY OTHER OBLIGOR ON THE NOTES OR ANY AFFILIATE OF THE ISSUER OR
ANY SUCH OTHER OBLIGOR.  IN THE CASE OF A DISPUTE AS TO SUCH RIGHT, ANY DECISION
BY THE TRUSTEE TAKEN UPON THE ADVICE OF COUNSEL SHALL BE FULL PROTECTION TO THE
TRUSTEE.  UPON REQUEST OF THE TRUSTEE, THE ISSUER SHALL FURNISH TO THE TRUSTEE
PROMPTLY AN OFFICERS’ CERTIFICATE LISTING AND IDENTIFYING ALL NOTES, IF ANY,
KNOWN BY THE ISSUER TO BE OWNED OR HELD BY OR FOR THE ACCOUNT OF ANY OF THE
ABOVE DESCRIBED PERSONS, AND, SUBJECT TO SECTION 7.01, THE TRUSTEE SHALL BE

FACTS THEREIN SET FORTH AND OF THE FACT THAT ALL NOTES NOT LISTED THEREIN ARE
OUTSTANDING FOR THE PURPOSE OF ANY SUCH DETERMINATION.

SECTION 8.05.  REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.  AT ANY TIME PRIOR
TO (BUT NOT AFTER) THE EVIDENCING TO THE TRUSTEE, AS PROVIDED IN SECTION 8.01,

PRINCIPAL AMOUNT OF THE NOTES SPECIFIED IN THIS INDENTURE IN CONNECTION WITH
SUCH ACTION, ANY HOLDER OF A NOTE WHICH IS SHOWN BY THE EVIDENCE TO BE INCLUDED
IN THE NOTES THE HOLDERS OF WHICH HAVE CONSENTED TO SUCH ACTION MAY, BY FILING
WRITTEN NOTICE WITH THE TRUSTEE AT ITS CORPORATE TRUST OFFICE AND UPON PROOF OF
HOLDING AS PROVIDED IN SECTION 8.02, REVOKE SUCH ACTION SO FAR AS CONCERNS SUCH
NOTE.  EXCEPT AS AFORESAID, ANY SUCH ACTION TAKEN BY THE HOLDER OF ANY NOTE
SHALL BE CONCLUSIVE AND BINDING UPON SUCH HOLDER AND UPON ALL FUTURE HOLDERS AND
OWNERS OF SUCH NOTE AND OF ANY NOTES ISSUED IN EXCHANGE OR SUBSTITUTION
THEREFOR, IRRESPECTIVE OF WHETHER ANY NOTATION IN REGARD THERETO IS MADE UPON
SUCH NOTE OR ANY NOTE ISSUED IN EXCHANGE OR SUBSTITUTION THEREFOR.

AND ONLY IF, THE CLOSING SALE PRICE OF THE COMMON STOCK FOR AT LEAST TWENTY (20)
TRADING DAYS (WHETHER OR NOT CONSECUTIVE) IN THE PERIOD OF THIRTY (30)
CONSECUTIVE TRADING DAYS ENDING ON THE LAST TRADING DAY OF THE PRECEDING
CALENDAR QUARTER IS MORE THAN 125% OF THE CONVERSION PRICE PER SHARE OF COMMON
STOCK IN EFFECT ON THE APPLICABLE TRADING DAY.  THE BOARD OF DIRECTORS WILL MAKE
APPROPRIATE ADJUSTMENTS, IN ITS GOOD FAITH DETERMINATION, TO ACCOUNT FOR ANY
ADJUSTMENT TO THE CONVERSION RATE THAT BECOMES EFFECTIVE, OR ANY EVENT REQUIRING
AN ADJUSTMENT TO THE CONVERSION RATE WHERE THE EX-DIVIDEND DATE OF THE EVENT
OCCURS, DURING THAT THIRTY (30) CONSECUTIVE TRADING DAY PERIOD.

(II)           CONVERSION UPON SATISFACTION OF TRADING PRICE CONDITION.  A
HOLDER MAY SURRENDER ANY OF ITS NOTES FOR CONVERSION DURING THE FIVE (5)
CONSECUTIVE TRADING DAY PERIOD FOLLOWING ANY FIVE (5) CONSECUTIVE TRADING DAY
PERIOD IN WHICH THE TRADING PRICE PER $1,000 PRINCIPAL AMOUNT OF NOTES (AS
DETERMINED FOLLOWING A REASONABLE REQUEST BY A HOLDER OF THE NOTES) WAS LESS
THAN 98% OF THE PRODUCT OF THE CLOSING SALE PRICE OF THE COMMON STOCK MULTIPLIED
BY THE CONVERSION RATE.

“Trading Price” means, with respect to the Notes on any date of determination,
the average of the secondary market bid quotations per $1,000 principal amount
of Notes obtained by the Trustee for a $5.0 million principal amount of Notes at
approximately 3:30 p.m., New York City time, on such determination date from two
independent nationally recognized securities dealers selected by the Issuer,
which may include one or more of the Initial Purchasers or any successor to such
entities.  If at least two such bids cannot reasonably be obtained by the
Trustee, but one such bid can reasonably be obtained by the Trustee, then one
bid shall be used. If the Trustee cannot reasonably obtain at least one bid for
a $5,000,000 principal amount of Notes from a nationally recognized securities
dealer or, in the reasonable judgment of the Issuer, the bid quotations are not
indicative of the secondary market value of the Notes, then the Trading Price
per $1,000 principal amount of Notes shall be deemed to be less than 98% of the

50

--------------------------------------------------------------------------------

product of the Closing Sale Price of the Common Stock and the Conversion Rate on
such determination date.

The Trustee shall have no obligation to determine the Trading Price of the Notes
unless the Issuer shall have requested such determination, and the Issuer shall
have no obligation to make such request unless a holder provides the Issuer with
written reasonable evidence that the Trading Price per $1,000 principal amount
of the Notes would be less than 98% of the product of the Closing Sale Price of
the Common Stock and the Conversion Rate, whereupon the Issuer shall instruct
the Trustee to determine the Trading Price of the Notes beginning on the next
Trading Day and on each successive Trading Day until the Trading Price is
greater than or equal to 98% of the product of the Closing Sale Price of the
Common Stock and the applicable Conversion Rate.

(III)          CONVERSION UPON NOTICE OF REDEMPTION.  A HOLDER MAY SURRENDER FOR
CONVERSION ANY OF THE NOTES CALLED FOR REDEMPTION AT ANY TIME PRIOR TO THE CLOSE
OF BUSINESS ON THE SECOND BUSINESS DAY PRIOR TO THE REDEMPTION DATE, EVEN IF THE
NOTES ARE NOT OTHERWISE CONVERTIBLE AT SUCH TIME.  THE RIGHT TO CONVERT NOTES
PURSUANT TO THIS CLAUSE (III) WILL EXPIRE AFTER THE CLOSE OF BUSINESS ON THE
SECOND BUSINESS DAY PRIOR TO THE REDEMPTION DATE UNLESS THE ISSUER DEFAULTS IN
MAKING THE PAYMENT DUE UPON REDEMPTION.  A HOLDER MAY CONVERT FEWER THAN ALL OF
ITS NOTES SO LONG AS THE NOTES CONVERTED ARE AN INTEGRAL MULTIPLE OF $1,000
PRINCIPAL AMOUNT AND THE REMAINING PRINCIPAL AMOUNT OF NOTES IS IN AN AUTHORIZED
DENOMINATION. HOWEVER, IF A HOLDER HAS ALREADY DELIVERED A REPURCHASE NOTICE
WITH RESPECT TO A NOTE, SUCH HOLDER MAY NOT SURRENDER SUCH NOTE FOR CONVERSION
UNTIL IT HAS WITHDRAWN SUCH NOTICE IN ACCORDANCE WITH THE APPLICABLE PROVISIONS
OF SECTION 3.08 HEREOF.

(IV)          CONVERSION UPON SPECIFIED TRANSACTIONS.  IF THE ISSUER ELECTS TO:
(1) DISTRIBUTE TO ALL HOLDERS OF COMMON STOCK RIGHTS ENTITLING THEM TO PURCHASE,
FOR A PERIOD EXPIRING WITHIN FORTY FIVE (45) DAYS AFTER THE DATE FIXED FOR
DETERMINATION OF STOCKHOLDERS ENTITLED TO RECEIVE SUCH RIGHTS, SHARES OF COMMON
STOCK AT LESS THAN THE CLOSING SALE PRICE OF THE COMMON STOCK ON THE TRADING DAY
IMMEDIATELY PRECEDING THE DECLARATION DATE OF SUCH DISTRIBUTION; OR (II)
DISTRIBUTE TO ALL HOLDERS OF COMMON STOCK ASSETS, DEBT SECURITIES OR CERTAIN
RIGHTS TO PURCHASE SECURITIES OF THE ISSUER, WHICH DISTRIBUTION HAS A PER SHARE
VALUE EXCEEDING 10% OF THE CLOSING SALE PRICE OF COMMON STOCK ON THE TRADING DAY
IMMEDIATELY PRECEDING THE DECLARATION DATE OF SUCH DISTRIBUTION, THE ISSUER
SHALL NOTIFY HOLDERS OF THE NOTES AT LEAST TWENTY (20) CALENDAR DAYS PRIOR TO
THE EX-DIVIDEND DATE FOR SUCH DISTRIBUTION.  FOLLOWING THE ISSUANCE OF SUCH
NOTICE, HOLDERS MAY SURRENDER THEIR NOTES FOR CONVERSION AT ANY TIME UNTIL THE
EARLIER OF THE CLOSE OF BUSINESS ON THE BUSINESS DAY PRIOR TO THE EX-DIVIDEND
DATE OR AN ANNOUNCEMENT BY THE ISSUER THAT SUCH DISTRIBUTION WILL NOT TAKE
PLACE; PROVIDED, HOWEVER, THAT A HOLDER MAY NOT CONVERT ITS NOTES PURSUANT TO
THIS SECTION 13.01(A)(IV) IF SUCH HOLDER MAY PARTICIPATE, ON AN AS-CONVERTED
BASIS (ASSUMING FOR THIS PURPOSE THAT THE NOTES WERE CONVERTIBLE SOLELY INTO
COMMON STOCK AT THE THEN APPLICABLE CONVERSION RATE), IN THE DISTRIBUTION
WITHOUT ANY CONVERSION OF NOTES. THE “EX-DIVIDEND DATE” MEANS, WITH RESPECT TO
ANY DISTRIBUTION ON SHARES OF COMMON STOCK, THE FIRST DATE UPON WHICH A SALE OF
SHARES OF COMMON STOCK DOES NOT AUTOMATICALLY TRANSFER THE RIGHT TO RECEIVE THE
RELEVANT DISTRIBUTION FROM THE SELLER OF SHARES OF COMMON STOCK TO THE BUYER.

51

--------------------------------------------------------------------------------

IN ADDITION, IF THE ISSUER IS PARTY TO A CONSOLIDATION, MERGER OR BINDING SHARE
EXCHANGE PURSUANT TO WHICH ALL OF THE COMMON STOCK WOULD BE EXCHANGED FOR CASH,
SECURITIES OR OTHER PROPERTY THAT IS NOT OTHERWISE A CHANGE IN CONTROL, A HOLDER
MAY SURRENDER NOTES FOR CONVERSION AT ANY TIME FROM AND INCLUDING THE DATE THAT
IS FIFTEEN (15) BUSINESS DAYS PRIOR TO THE ANTICIPATED EFFECTIVE DATE OF THE
TRANSACTION UP TO AND INCLUDING FIVE (5) BUSINESS DAYS AFTER THE EFFECTIVE DATE
OF SUCH TRANSACTION.  THE ISSUER SHALL NOTIFY HOLDERS OF NOTES AS PROMPTLY AS
PRACTICABLE FOLLOWING THE DATE IT PUBLICLY ANNOUNCES SUCH TRANSACTION (BUT IN NO
EVENT LESS THAN FIFTEEN (15) BUSINESS DAYS PRIOR TO THE ANTICIPATED EFFECTIVE
TIME OF SUCH TRANSACTION).

If a Change in Control occurs prior to the Stated Maturity as a result of a
transaction described in clauses (1) or (2) of the definition of “Change in
Control,” a holder will have the right to convert its Notes at any time from and
including the Effective Date of such transaction up to and including the earlier
of the 30th Business Day following the Effective Date of the transaction and the
second Business Day prior to the Stated Maturity, provided that, if a holder has
already delivered a Repurchase Notice with respect to a Note, such holder may
not surrender such Note for conversion until it has withdrawn such notice in
accordance with the applicable provisions of Section 3.08 hereof. The Issuer
will notify holders as promptly as practicable following the date that it
publicly announces such Change in Control (but in no event later than five (5)
Business Days prior to the Effective Date of such Change in Control).

(V)           CONVERSION UPON DELISTING OF THE COMMON STOCK. A HOLDER OF NOTES
MAY SURRENDER ANY OF ITS NOTES FOR CONVERSION AT ANY TIME BEGINNING ON THE FIRST
BUSINESS DAY AFTER THE COMMON STOCK HAS CEASED TO BE LISTED ON A U.S. NATIONAL
OR REGIONAL SECURITIES EXCHANGE FOR A 30 CONSECUTIVE TRADING DAY PERIOD.

(B)           WHENEVER THE NOTES SHALL BECOME CONVERTIBLE PURSUANT TO THIS
SECTION 13.01, THE ISSUER OR, AT THE ISSUER’S REQUEST, THE TRUSTEE IN THE NAME
AND AT THE EXPENSE OF THE ISSUER, SHALL NOTIFY THE HOLDERS OF THE EVENT
TRIGGERING SUCH CONVERTIBILITY IN THE MANNER PROVIDED IN SECTION 15.03, AND THE
ISSUER SHALL ALSO PUBLICLY ANNOUNCE SUCH INFORMATION AND PUBLISH IT ON ITS WEB
SITE.  ANY NOTICE SO GIVEN SHALL BE CONCLUSIVELY PRESUMED TO HAVE BEEN DULY
GIVEN, WHETHER OR NOT THE HOLDER RECEIVES SUCH NOTICE.

(C)           A NOTE IN RESPECT OF WHICH A HOLDER HAS DELIVERED A REPURCHASE
NOTICE EXERCISING SUCH HOLDER’S RIGHT TO REQUIRE THE ISSUER TO REPURCHASE SUCH
NOTE PURSUANT TO SECTION 3.05 MAY BE CONVERTED ONLY IF SUCH REPURCHASE NOTICE IS
WITHDRAWN IN ACCORDANCE WITH SECTION 3.08 PRIOR TO THE CLOSE OF BUSINESS ON THE
THIRD BUSINESS DAY PRIOR TO THE CHANGE IN CONTROL REPURCHASE DATE.

(D)           A HOLDER OF NOTES IS NOT ENTITLED TO ANY RIGHTS OF A HOLDER OF
COMMON STOCK UNTIL SUCH HOLDER HAS CONVERTED ITS NOTES AND RECEIVED UPON
CONVERSION THEREOF SHARES OF COMMON STOCK.  THE PERSON IN WHOSE NAME ANY
CERTIFICATE OR CERTIFICATES FOR SHARES OF COMMON STOCK SHALL BE ISSUABLE UPON
SUCH CONVERSION, IF ANY, SHALL BECOME ON THE DATE ANY SUCH CERTIFICATE OR
CERTIFICATES ARE DELIVERED TO SUCH HOLDER IN ACCORDANCE WITH THE PROVISIONS OF
THIS ARTICLE 13, THE HOLDER OF RECORD OF THE SHARES REPRESENTED THEREBY.

52

--------------------------------------------------------------------------------

SECTION 13.02.  EXERCISE OF CONVERSION RIGHT; NO ADJUSTMENT FOR INTEREST OR
DIVIDENDS.  IN ORDER TO EXERCISE THE CONVERSION RIGHT WITH RESPECT TO ANY NOTE
IN CERTIFICATED FORM, THE ISSUER MUST RECEIVE AT THE OFFICE OR AGENCY OF THE
ISSUER MAINTAINED FOR THAT PURPOSE IN THE CITY OF NEW YORK OR, AT THE OPTION OF
SUCH HOLDER, THE CORPORATE TRUST OFFICE, SUCH NOTE WITH THE ORIGINAL OR
FACSIMILE OF THE FORM ENTITLED “CONVERSION NOTICE” ON THE REVERSE THEREOF, DULY
COMPLETED AND MANUALLY SIGNED, TOGETHER WITH SUCH NOTES DULY ENDORSED FOR
TRANSFER, ACCOMPANIED BY THE FUNDS, IF ANY, REQUIRED BY THIS SECTION 13.02. 
SUCH NOTICE SHALL ALSO STATE THE NAME OR NAMES (WITH ADDRESS OR ADDRESSES) IN
WHICH THE CERTIFICATE OR CERTIFICATES FOR SHARES OF COMMON STOCK, IF ANY, WHICH
SHALL BE ISSUABLE ON SUCH CONVERSION SHALL BE ISSUED (IF OTHER THAN IN THE NAME
OF THE HOLDER TENDERING SUCH NOTE FOR CONVERSION), AND SHALL BE ACCOMPANIED BY
TRANSFER OR SIMILAR TAXES, IF REQUIRED PURSUANT TO SECTION 13.07.

In order to exercise the conversion right with respect to any interest in a
Global Note, the beneficial holder must complete, or cause to be completed, the
appropriate instruction form for conversion pursuant to the Depositary’s
book-entry conversion program; deliver, or cause to be delivered, by book-entry
delivery such interest in such Global Note; furnish appropriate endorsements and
transfer documents if required by the Issuer or the Trustee or the Conversion
Agent; and pay the funds, if any, required by this Section 13.02 and any
transfer taxes if required pursuant to Section 13.07.

Each conversion shall be deemed to have been effected as to any such Note (or
portion thereof) on the date on which the requirements set forth above in this
Section 13.02 have been satisfied as to such Note (or portion thereof) (the
“Conversion Date”).

Except as set forth in the next succeeding paragraph, upon conversion of a Note,
a holder shall not be entitled to receive any cash payment in respect of
interest, and the Issuer shall not be required to adjust the Conversion Rate to
account for any accrued and unpaid interest (including Additional Interest, if
any).  The delivery by the Issuer to the holder of cash and Common Stock, if
any, upon conversion shall be deemed to satisfy the Issuer’s obligation with
respect to Notes tendered for conversion. Accordingly, upon conversion of Notes,
any accrued but unpaid interest shall be deemed to be paid in full, rather than
cancelled, extinguished or forfeited.

Holders of Notes at the close of business on a Record Date for an interest
payment shall receive payment of the interest payable on the corresponding
Interest Payment Date notwithstanding the conversion of such Notes at any time
after the close of business on the applicable Record Date and on or prior to the
corresponding Interest Payment Date.  Accordingly, any Note or portion thereof
surrendered for conversion after the close of business on the Record Date for
any Interest Payment Date and on or prior to the corresponding Interest Payment
Date shall be accompanied by payment, in immediately available funds or other
funds acceptable to the Issuer, of an amount equal to the interest otherwise
payable on such Interest Payment Date on the principal amount being converted;
provided that no such payment need be made (1) if the Issuer has specified a
Redemption Date that is after a Record Date and on or prior to the corresponding
Interest Payment Date, (2) to the extent of any overdue interest and Additional
Interest, if any overdue interest and Additional Interest, as applicable, exists
at the time of conversion with respect to such Notes, or (3) in respect of any
conversion that occurs after the Record Date for the interest payment due on
September 15, 2011.  Except as otherwise provided above in this Article 13, no
payment or other adjustment shall be made for interest

53

--------------------------------------------------------------------------------

accrued on any Note converted or for dividends on any shares issued upon the
conversion of such Note as provided in this Article 13.

In case any Note of a denomination greater than $1,000 shall be surrendered for
partial conversion, and subject to Section 2.04, the Issuer shall execute and
the Trustee shall authenticate and deliver to the holder of the Note so
surrendered, without charge to the holder, a new Note or Notes in authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Note.

Upon surrender of a Note for conversion, the holder shall deliver to the Issuer
an amount in cash equal to the amount that the Issuer is required to deduct and
withhold under applicable law in connection with such conversion; provided,
however, that if the holder does not deliver such cash, the Issuer may deduct
and withhold from the consideration otherwise deliverable to such holder the
amount required to be deducted and withheld under applicable law.

Upon the conversion of an interest in a Global Note, the Trustee (or other
Conversion Agent appointed by the Issuer), or the Custodian at the direction of
the Trustee (or other Conversion Agent appointed by the Issuer), shall make a
notation on such Global Note as to the reduction in the principal amount
represented thereby.  The Issuer shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the
Trustee.

SECTION 13.03.  CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES.  NO FRACTIONAL
SHARES OF COMMON STOCK OR SCRIP CERTIFICATES REPRESENTING FRACTIONAL SHARES
SHALL BE ISSUED UPON CONVERSION OF NOTES.   IF MORE THAN ONE NOTE SHALL BE
SURRENDERED FOR CONVERSION AT ONE TIME BY THE SAME HOLDER, THE NUMBER OF FULL
SHARES THAT SHALL BE ISSUABLE UPON CONVERSION SHALL BE COMPUTED ON THE BASIS OF
THE AGGREGATE PRINCIPAL AMOUNT OF THE NOTES (OR SPECIFIED PORTIONS THEREOF TO
THE EXTENT PERMITTED HEREBY) SO SURRENDERED.   THE ISSUER SHALL DELIVER CASH IN
LIEU OF ANY FRACTIONAL SHARES OF COMMON STOCK ISSUABLE IN CONNECTION WITH
PAYMENT OF THE SETTLEMENT AMOUNT DETERMINED IN ACCORDANCE WITH THE PROVISIONS OF
SECTION 13.12 BASED ON THE CLOSING SALE PRICE OF THE COMMON STOCK ON THE LAST
DAY OF THE APPLICABLE OBSERVATION PERIOD.

SECTION 13.04.  CONVERSION RATE.  THE CONVERSION RATE FOR THE NOTES IS 26.6326
SHARES OF COMMON STOCK PER EACH $1,000 PRINCIPAL AMOUNT OF THE NOTES (HEREIN
CALLED THE “CONVERSION RATE”), SUBJECT TO ADJUSTMENT AS PROVIDED IN SECTIONS
13.05 AND 13.13.

SECTION 13.05.  ADJUSTMENT OF CONVERSION RATE.  THE CONVERSION RATE SHALL BE
ADJUSTED BY THE ISSUER FROM TIME TO TIME AS FOLLOWS:

(A)           IF THE ISSUER ISSUES COMMON STOCK AS A DIVIDEND OR DISTRIBUTION ON
COMMON STOCK TO ALL HOLDERS OF COMMON STOCK, OR IF THE ISSUER EFFECTS A SHARE
SPLIT OR SHARE COMBINATION, THE CONVERSION RATE WILL BE ADJUSTED BASED ON THE
FOLLOWING FORMULA:

CR1 = CR0 x OS1/OS0

where

54

--------------------------------------------------------------------------------

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate in effect taking such event into account

OS0 =     the number of shares of Common Stock outstanding immediately prior to
such event

OS1 =     the number of shares of Common Stock outstanding immediately after
such event.

Any adjustment made pursuant to this clause (a) shall become effective on the
date that is immediately after (x) the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution or (y) the
date on which such split or combination becomes effective, as applicable. If any
dividend or distribution described in this clause (a) is declared but not so
paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate
that would then be in effect if such dividend or distribution had not been
declared.

(B)           IF THE ISSUER ISSUES TO ALL HOLDERS OF COMMON STOCK ANY RIGHTS,
WARRANTS, OPTIONS OR OTHER SECURITIES ENTITLING THEM FOR A PERIOD OF NOT MORE
THAN 45 DAYS AFTER THE DATE OF ISSUANCE THEREOF TO SUBSCRIBE FOR OR PURCHASE
COMMON STOCK, OR IF THE ISSUER ISSUES TO ALL HOLDERS OF COMMON STOCK SECURITIES
CONVERTIBLE INTO COMMON STOCK FOR A PERIOD OF NOT MORE THAN 45 DAYS AFTER THE
DATE OF ISSUANCE THEREOF, IN EITHER CASE AT AN EXERCISE PRICE PER SHARE OF
COMMON STOCK OR A CONVERSION PRICE PER SHARE OF COMMON STOCK LESS THAN THE
CLOSING SALE PRICE OF THE COMMON STOCK ON THE BUSINESS DAY IMMEDIATELY PRECEDING
THE TIME OF ANNOUNCEMENT OF SUCH ISSUANCE, THE CONVERSION RATE WILL BE ADJUSTED
BASED ON THE FOLLOWING FORMULA:

CR1 = CR0 x (OS0+X)/(OS0+Y)

where

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate taking such event into account

OS0 =     the number of shares of Common Stock outstanding immediately prior to
such event

X =          the total number of shares of Common Stock issuable pursuant to
such rights, warrants, options, other securities or convertible securities

Y =          the number of shares of Common Stock equal to the quotient of
(A) the aggregate price payable to exercise such rights, warrants, options,
other securities or convertible securities and (B) the

55

--------------------------------------------------------------------------------

average of the Closing Sale Prices of the Common Stock for the 10 consecutive
Trading Days prior to the Business Day immediately preceding the date of
announcement for the issuance of such rights, warrants, options, other
securities or convertible securities.

For purposes of this clause (b), in determining whether any rights, warrants,
options, other securities or convertible securities entitle the holders to
subscribe for or purchase, or exercise a conversion right for, Common Stock at
less than the applicable Closing Sale Price of the Common Stock, and in
determining the aggregate exercise or conversion price payable for such Common
Stock, there shall be taken into account any consideration received by the
Issuer for such rights, warrants, options, other securities or convertible
securities and any amount payable on exercise or conversion thereof, with the
value of such consideration, if other than cash, to be determined by the Board
of Directors of the Issuer.  If any right, warrant, option, other security or
convertible security described in this clause (b) is not exercised or converted
prior to the expiration of the exercisability or convertibility thereof, the new
Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect if such right, warrant, option, other security or convertible security
had not been so issued.

(C)           IF THE ISSUER DISTRIBUTES CAPITAL STOCK, EVIDENCES OF INDEBTEDNESS
OR OTHER ASSETS OR PROPERTY OF THE ISSUER TO ALL HOLDERS OF COMMON STOCK,
EXCLUDING:

(I)            DIVIDENDS, DISTRIBUTIONS, RIGHTS, WARRANTS, OPTIONS, OTHER
SECURITIES OR CONVERTIBLE SECURITIES REFERRED TO IN CLAUSE (A) OR (B) ABOVE,

(II)           DIVIDENDS OR DISTRIBUTIONS PAID EXCLUSIVELY IN CASH, AND

(III)          SPIN-OFFS DESCRIBED BELOW IN THIS CLAUSE (C),

then the Conversion Rate will be adjusted based on the following formula:

CR1 =     CR0 x SP0/(SP0-FMV)

where

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate taking such event into account

SP0 =      the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding the ex-dividend date for such distribution

FMV=     the fair market value (as determined in good faith by the Board of
Directors of the Issuer) of the capital stock, evidences of indebtedness, assets
or property distributed with respect to each outstanding share of Common Stock
on the earlier of the record date or the ex-dividend date for such distribution.

56

--------------------------------------------------------------------------------

An adjustment to the Conversion Rate made pursuant to the immediately preceding
clause shall be made successively whenever any such distribution is made and
shall become effective on the ex-dividend date for such distribution.

If the Issuer distributes to all holders of Common Stock capital stock of any
class or series, or similar equity interest, of or relating to a subsidiary or
other business unit of the Issuer (a “Spin-Off”), the Conversion Rate in effect
immediately before the close of business on the date fixed for determination of
holders of Common Stock entitled to receive such distribution will be adjusted
based on the following formula:

CR1 =     CR0 x (FMV0+MP0)/MP0

where

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate taking such event into account

FMV0 =          the average of the Closing Sale Prices of the capital stock or
similar equity interest distributed to holders of Common Stock applicable to one
share of Common Stock over the first 10 consecutive Trading Days after the
effective date of the Spin-Off

MP0 =            the average of the Closing Sale Prices of the Common Stock over
the first 10 consecutive Trading Days after the effective date of the Spin-Off.

An adjustment to the Conversion Rate made pursuant to the immediately preceding
clause will occur on the 10th Trading Day from and including the effective date
of the Spin-Off.

If any such dividend or distribution described in this clause (c) is declared
but not paid or made, the new Conversion Rate shall be readjusted to be the
Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

(D)           IF THE ISSUER PAYS OR MAKES ANY CASH DIVIDEND OR DISTRIBUTION IN
RESPECT OF ANY OF ITS QUARTERLY FISCAL PERIODS (WITHOUT REGARD TO WHEN PAID) TO
ALL HOLDERS OF COMMON STOCK IN AN AGGREGATE AMOUNT THAT, TOGETHER WITH OTHER
CASH DIVIDENDS OR DISTRIBUTIONS PAID OR MADE IN RESPECT OF SUCH QUARTERLY FISCAL
PERIOD, EXCEEDS THE PRODUCT OF $0.3125 (THE “REFERENCE DIVIDEND”) MULTIPLIED BY
THE NUMBER OF SHARES OF COMMON STOCK OUTSTANDING ON THE RECORD DATE FOR SUCH
DISTRIBUTION, THE CONVERSION RATE WILL BE ADJUSTED BASED ON THE FOLLOWING
FORMULA:

CR1 =     CR0 x SP0/(SP0-C)

where

57

--------------------------------------------------------------------------------

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate taking such event into account

SP0 =      the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding the ex-dividend date for such distribution

C =          the amount in cash per share of Common Stock that the Issuer
distributes to holders of Common Stock in respect of such quarterly fiscal
period that exceeds the Reference Dividend.

An adjustment to the Conversion Rate made pursuant to this clause (d) shall
become effective on the ex-dividend date for such dividend or distribution.  If
any dividend or distribution described in this clause (d) is declared but not so
paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate
that would then be in effect if such dividend or distribution had not been
declared.

The Reference Dividend shall be subject to adjustment on account of any of the
events set forth in clauses (a), (b) and (c) above and clause (e) below.  Any
such adjustment will be effected by multiplying the Reference Dividend by a
fraction, the numerator of which will equal the Conversion Rate in effect
immediately prior to the adjustment on account of such event and the denominator
of which will equal the Conversion Rate as adjusted.

(E)           IF THE ISSUER OR ANY OF ITS SUBSIDIARIES MAKES A PAYMENT IN
RESPECT OF A TENDER OFFER OR EXCHANGE OFFER FOR COMMON STOCK TO THE EXTENT THAT
THE CASH AND VALUE OF ANY OTHER CONSIDERATION INCLUDED IN THE PAYMENT PER SHARE
OF COMMON STOCK EXCEEDS THE CLOSING SALE PRICE OF THE COMMON STOCK ON THE
TRADING DAY NEXT SUCCEEDING THE LAST DATE ON WHICH TENDERS OR EXCHANGES MAY BE
MADE PURSUANT TO SUCH TENDER OR EXCHANGE OFFER (THE “EXPIRATION TIME”), THE
CONVERSION RATE WILL BE ADJUSTED BASED ON THE FOLLOWING FORMULA:

CR1 = CR0 x (AC + (SP1 x OS1))/(SP1 x OS0)

where

CR0 =     the Conversion Rate in effect immediately prior to the adjustment
relating to such event

CR1 =     the new Conversion Rate taking such event into account

AC =       the aggregate value of all cash and any other consideration (as
determined by the Board of Directors of the Issuer) paid or payable for Common
Stock purchased in such tender or exchange offer

OS0 =     the number of shares of Common Stock outstanding immediately prior to
the date such tender or exchange offer expires

58

--------------------------------------------------------------------------------

OS1 =     the number of shares of Common Stock outstanding immediately after
such tender or exchange offer expires (after giving effect to the purchase or
exchange of shares pursuant to such tender or exchange offer)

SP1 =      the average of the Closing Sale Prices of Common Stock for the 10
consecutive Trading Days commencing on the Trading Day next succeeding the date
such tender or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the
Conversion Rate, no adjustment to the Conversion Rate will be made.

Any adjustment to the Conversion Rate made pursuant to this clause (e) shall
become effective on the date immediately following the determination of the
average of the Closing Sale Prices of Common Stock for purposes of SP1 above. 
If the Issuer or one of its subsidiaries is obligated to purchase Common Stock
pursuant to any such tender or exchange offer but is permanently prevented by
applicable law from effecting any such purchase or all such purchases are
rescinded, the new Conversion Rate shall be readjusted to be the Conversion Rate
that would be in effect if such tender or exchange offer had not been made.

(F)            IN ADDITION TO THE ADJUSTMENTS PURSUANT TO CLAUSES (A) THROUGH
(E) ABOVE, THE ISSUER MAY INCREASE THE CONVERSION RATE IN ORDER TO AVOID OR
DIMINISH ANY INCOME TAX TO HOLDERS OF COMMON STOCK RESULTING FROM ANY DIVIDEND
OR DISTRIBUTION OF CAPITAL SHARES (OR RIGHTS TO ACQUIRE COMMON STOCK) OR FROM
ANY EVENT TREATED AS SUCH FOR INCOME TAX PURPOSES.  THE ISSUER MAY ALSO, FROM
TIME TO TIME, TO THE EXTENT PERMITTED BY APPLICABLE LAW, INCREASE THE CONVERSION
RATE BY ANY AMOUNT FOR ANY PERIOD IF THE ISSUER HAS DETERMINED THAT SUCH
INCREASE WOULD BE IN THE BEST INTERESTS OF THE ISSUER.  IF THE ISSUER MAKES SUCH
DETERMINATION, IT WILL BE CONCLUSIVE AND THE ISSUER WILL MAIL TO HOLDERS OF THE
NOTES A NOTICE OF THE INCREASED CONVERSION RATE AND THE PERIOD DURING WHICH IT
WILL BE IN EFFECT AT LEAST FIFTEEN (15) DAYS PRIOR TO THE DATE THE INCREASED
CONVERSION RATE TAKES EFFECT IN ACCORDANCE WITH APPLICABLE LAW.

(G)           IF, IN CONNECTION WITH ANY ADJUSTMENT TO THE CONVERSION RATE AS
SET FORTH IN THIS SECTION 13.05 A HOLDER SHALL BE DEEMED FOR U.S. FEDERAL TAX
PURPOSES TO HAVE RECEIVED A DISTRIBUTION, THE ISSUER MAY SET OFF ANY WITHHOLDING
TAX IT REASONABLY BELIEVES IT IS REQUIRED TO COLLECT WITH RESPECT TO ANY SUCH
DEEMED DISTRIBUTION AGAINST CASH PAYMENTS OF INTEREST IN ACCORDANCE WITH THE
PROVISIONS OF SECTION 4.01 HEREOF OR FROM CASH AND COMMON STOCK, IF ANY,
OTHERWISE DELIVERABLE TO A HOLDER UPON A CONVERSION OF NOTES IN ACCORDANCE WITH
THE PROVISIONS OF SECTION 13.12 HEREOF OR A REDEMPTION OR REPURCHASE OF A NOTE
IN ACCORDANCE WITH THE PROVISIONS OF ARTICLE 3 HEREOF.

(H)           THE ISSUER WILL NOT MAKE ANY ADJUSTMENT TO THE CONVERSION RATE IF
HOLDERS OF THE NOTES ARE PERMITTED TO PARTICIPATE, ON AN AS-CONVERTED BASIS, IN
THE TRANSACTIONS DESCRIBED ABOVE.

59

--------------------------------------------------------------------------------

(I)            NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, IN
ADDITION TO THE OTHER EVENTS SET FORTH HEREIN ON ACCOUNT OF WHICH NO ADJUSTMENT
TO THE CONVERSION RATE SHALL BE MADE, THE APPLICABLE CONVERSION RATE SHALL NOT
BE ADJUSTED FOR: (I) THE ISSUANCE OF ANY COMMON STOCK PURSUANT TO ANY PRESENT OR
FUTURE PLAN PROVIDING FOR THE REINVESTMENT OF DIVIDENDS OR INTEREST PAYABLE ON
SECURITIES OF THE ISSUER AND THE INVESTMENT OF ADDITIONAL OPTIONAL AMOUNTS IN
COMMON STOCK UNDER ANY PLAN; (II) THE ISSUANCE OF ANY SHARES OF COMMON STOCK OR
OPTIONS OR RIGHTS TO PURCHASE THOSE SHARES PURSUANT TO ANY PRESENT OR FUTURE
EMPLOYEE, DIRECTOR OR CONSULTANT BENEFIT PLAN, EMPLOYEE AGREEMENT OR ARRANGEMENT
OR PROGRAM OF THE ISSUER; (III) THE ISSUANCE OF ANY SHARES OF COMMON STOCK
PURSUANT TO ANY OPTION, WARRANT, RIGHT, OR EXERCISABLE, EXCHANGEABLE OR
CONVERTIBLE SECURITY OUTSTANDING AS OF THE DATE THE NOTES WERE FIRST ISSUED;
(IV) A CHANGE IN THE PAR VALUE OF THE COMMON STOCK; (V) ACCUMULATED AND UNPAID
DIVIDENDS OR DISTRIBUTIONS; AND (VI) AS A RESULT OF A TENDER OFFER SOLELY TO
HOLDERS OF FEWER THAN 100 SHARES OF COMMON STOCK.

(J)            NO ADJUSTMENT IN THE CONVERSION RATE WILL BE REQUIRED UNLESS THE
ADJUSTMENT WOULD REQUIRE AN INCREASE OR DECREASE OF AT LEAST 1% OF THE
CONVERSION PRICE. IF THE ADJUSTMENT IS NOT MADE BECAUSE THE ADJUSTMENT DOES NOT
CHANGE THE CONVERSION PRICE BY AT LEAST 1%, THEN THE ADJUSTMENT THAT IS NOT MADE
WILL BE CARRIED FORWARD AND TAKEN INTO ACCOUNT IN ANY FUTURE ADJUSTMENT.  ALL
REQUIRED CALCULATIONS WILL BE MADE TO THE NEAREST CENT OR 1/1000TH OF A SHARE,
AS THE CASE MAY BE.  NOTWITHSTANDING THE FOREGOING, IF THE NOTES ARE CALLED FOR
REDEMPTION, ALL ADJUSTMENTS NOT PREVIOUSLY MADE WILL BE MADE ON THE APPLICABLE
REDEMPTION DATE.

(K)           WHENEVER THE CONVERSION RATE IS ADJUSTED AS HEREIN PROVIDED, THE
ISSUER SHALL PROMPTLY FILE WITH THE TRUSTEE AND ANY CONVERSION AGENT OTHER THAN
THE TRUSTEE, AN OFFICERS’ CERTIFICATE SETTING FORTH THE CONVERSION RATE AFTER
SUCH ADJUSTMENT AND SETTING FORTH A BRIEF STATEMENT OF THE FACTS REQUIRING SUCH
ADJUSTMENT.  UNLESS AND UNTIL A RESPONSIBLE OFFICER OF THE TRUSTEE SHALL HAVE
RECEIVED SUCH OFFICERS’ CERTIFICATE, THE TRUSTEE SHALL NOT BE DEEMED TO HAVE
KNOWLEDGE OF ANY ADJUSTMENT OF THE CONVERSION RATE AND MAY ASSUME THAT THE LAST
CONVERSION RATE OF WHICH IT HAS KNOWLEDGE IS STILL IN EFFECT.  PROMPTLY AFTER
DELIVERY OF SUCH CERTIFICATE, THE ISSUER SHALL PREPARE A NOTICE OF SUCH
ADJUSTMENT OF THE CONVERSION RATE SETTING FORTH THE ADJUSTED CONVERSION RATE AND
THE DATE ON WHICH EACH ADJUSTMENT BECOMES EFFECTIVE AND SHALL MAIL SUCH NOTICE
OF SUCH ADJUSTMENT OF THE CONVERSION RATE TO THE HOLDERS OF THE NOTES WITHIN 20
BUSINESS DAYS OF THE EFFECTIVE DATE OF SUCH ADJUSTMENT.  FAILURE TO DELIVER SUCH
NOTICE SHALL NOT AFFECT THE LEGALITY OR VALIDITY OF ANY SUCH ADJUSTMENT.

(L)            FOR PURPOSES OF THIS SECTION 13.05, THE NUMBER OF SHARES OF
COMMON STOCK AT ANY TIME OUTSTANDING SHALL NOT INCLUDE SHARES HELD IN THE
TREASURY OF THE ISSUER BUT SHALL INCLUDE SHARES ISSUABLE IN RESPECT OF SCRIP
CERTIFICATES ISSUED IN LIEU OF FRACTIONS OF SHARES OF COMMON STOCK.

(M)          NOTWITHSTANDING ANYTHING IN THIS SECTION 13.05 TO THE CONTRARY, IN

--------------------------------------------------------------------------------

SECTION 13.06.  CHANGE IN CONVERSION RIGHT UPON CERTAIN RECLASSIFICATIONS,
BUSINESS COMBINATIONS AND ASSET SALES.

(A)           IF THE ISSUER IS A PARTY TO A CONSOLIDATION, MERGER OR BINDING
SHARE EXCHANGE (INCLUDING, WITHOUT LIMITATION, BY WAY OF A RECAPITALIZATION,
RECLASSIFICATION OR CHANGE OF COMMON STOCK (OTHER THAN CHANGES RESULTING FROM A
SUBDIVISION OR COMBINATION) OR A SALE, LEASE OR TRANSFER TO A THIRD PARTY OF THE
ISSUER’S AND THE ISSUER’S SUBSIDIARIES’ CONSOLIDATED ASSETS SUBSTANTIALLY AS AN
ENTIRETY) PURSUANT TO WHICH ALL OF THE COMMON STOCK IS CONVERTED INTO CASH,
SECURITIES OR OTHER PROPERTY, THEN THE ISSUER, OR SUCH SUCCESSOR OR PURCHASING
CORPORATION, AS THE CASE MAY BE, SHALL, AS A CONDITION PRECEDENT TO SUCH
CONSOLIDATION, MERGER OR BINDING SHARE EXCHANGE OR SALE, LEASE OR TRANSFER,
EXECUTE AND DELIVER TO THE TRUSTEE A SUPPLEMENTAL INDENTURE PROVIDING THAT AT
THE EFFECTIVE DATE OF THE TRANSACTION ANY CONVERSION OF NOTES AND THE
DETERMINATION OF THE SUM OF THE DAILY SHARE AMOUNTS WILL BE BASED ON, AND
DETERMINED BY REFERENCE TO, THE KIND AND AMOUNT OF CASH, SECURITIES OR OTHER
PROPERTY THAT THE HOLDER WOULD HAVE RECEIVED IF SUCH HOLDER HAD CONVERTED ITS
NOTES INTO SHARES OF COMMON STOCK IMMEDIATELY PRIOR TO THE EFFECTIVE DATE OF THE
TRANSACTION.

(B)           IN THE EVENT THE ISSUER SHALL EXECUTE A SUPPLEMENTAL INDENTURE
PURSUANT TO THIS SECTION 13.06, THE ISSUER SHALL PROMPTLY FILE WITH THE TRUSTEE
AN OPINION OF COUNSEL STATING THAT SUCH SUPPLEMENTAL INDENTURE IS AUTHORIZED OR
PERMITTED BY THIS INDENTURE AND AN OFFICERS’ CERTIFICATE BRIEFLY STATING THE
REASONS THEREFOR, THE KIND OR AMOUNT OF CASH, SECURITIES OR OTHER PROPERTY
RECEIVABLE BY HOLDERS OF THE NOTES UPON THE CONVERSION OF THEIR NOTES AFTER ANY
SUCH RECLASSIFICATION, CHANGE, CONSOLIDATION, MERGER, BINDING SHARE EXCHANGE,
SALE, TRANSFER, LEASE OR CONVEYANCE, ANY ADJUSTMENT TO BE MADE WITH RESPECT
THERETO AND THAT ALL CONDITIONS PRECEDENT HAVE BEEN COMPLIED WITH.

(C)           FOR PURPOSES OF THIS SECTION 13.06, WHERE A CONSOLIDATION, MERGER
OR BINDING SHARE EXCHANGE INVOLVES A TRANSACTION THAT CAUSES COMMON STOCK TO BE
CONVERTED INTO THE RIGHT TO RECEIVE MORE THAN A SINGLE TYPE OF CONSIDERATION
BASED UPON ANY FORM OF SHAREHOLDER ELECTION, SUCH CONSIDERATION WILL BE DEEMED
TO BE THE WEIGHTED AVERAGE OF THE TYPES AND AMOUNTS OF CONSIDERATION RECEIVED BY
THE HOLDERS OF COMMON STOCK THAT AFFIRMATIVELY MAKE SUCH AN ELECTION.

(D)           IF THIS SECTION 13.06 APPLIES TO ANY EVENT OR OCCURRENCE, SECTION
13.05 SHALL NOT APPLY.  THE PROVISIONS OF THIS SECTION 13.06 SHALL SIMILARLY
APPLY TO SUCCESSIVE RECLASSIFICATIONS, CHANGES, CONSOLIDATIONS, MERGERS, SALES,
TRANSFERS, LEASES, CONVEYANCES OR OTHER DISPOSITIONS.

SECTION 13.07.  TAXES ON SHARES ISSUED.  THE ISSUE OF STOCK CERTIFICATES, IF
ANY, ON CONVERSION OF NOTES SHALL BE MADE WITHOUT CHARGE TO THE CONVERTING
NOTEHOLDER FOR ANY DOCUMENTARY, STAMP OR SIMILAR ISSUE OR TRANSFER TAX IN
RESPECT OF THE ISSUE THEREOF.  THE ISSUER SHALL NOT, HOWEVER, BE REQUIRED TO PAY
ANY SUCH TAX WHICH MAY BE PAYABLE IN RESPECT OF ANY TRANSFER INVOLVED IN THE
ISSUE AND DELIVERY OF STOCK IN ANY NAME OTHER THAN THAT OF THE HOLDER OF ANY
NOTE CONVERTED, AND THE ISSUER SHALL NOT BE REQUIRED TO ISSUE OR DELIVER ANY
SUCH STOCK CERTIFICATE UNLESS AND UNTIL THE PERSON OR PERSONS REQUESTING THE
ISSUE THEREOF SHALL HAVE PAID TO THE ISSUER THE AMOUNT OF SUCH TAX OR SHALL HAVE
ESTABLISHED TO THE SATISFACTION OF THE ISSUER THAT SUCH TAX HAS BEEN PAID.

61

--------------------------------------------------------------------------------

SECTION 13.08.  RESERVATION OF SHARES, SHARES TO BE FULLY PAID; COMPLIANCE WITH
GOVERNMENTAL REQUIREMENTS.  THE ISSUER SHALL PROVIDE, FREE FROM PREEMPTIVE
RIGHTS, OUT OF ITS AUTHORIZED BUT UNISSUED SHARES OR SHARES HELD IN TREASURY,
SUFFICIENT SHARES OF COMMON STOCK TO PROVIDE FOR THE CONVERSION OF THE NOTES AS
REQUIRED BY THIS INDENTURE FROM TIME TO TIME AS SUCH NOTES ARE PRESENTED FOR
CONVERSION.

Before taking any action which would cause an adjustment increasing the
Conversion Rate to an amount that would cause the Conversion Price to be reduced
below the then par value, if any, of the shares of Common Stock issuable, if
any, upon conversion of the Notes, the Issuer will take all corporate action
which may, in the opinion of its counsel, be necessary in order that the Issuer
may validly and legally issue shares of such Common Stock at such adjusted
Conversion Rate.

The Issuer covenants that all shares of Common Stock, if any, which may be
issued upon conversion of Notes will upon issue be fully paid and non-assessable
and free from all taxes, liens and charges with respect to the issue thereof.

SECTION 13.09.  RESPONSIBILITY OF TRUSTEE.  THE TRUSTEE AND ANY OTHER CONVERSION
AGENT SHALL NOT AT ANY TIME BE UNDER ANY DUTY OR RESPONSIBILITY TO ANY HOLDER OF
NOTES TO DETERMINE THE CONVERSION RATE OR WHETHER ANY FACTS EXIST WHICH MAY
REQUIRE ANY ADJUSTMENT OF THE CONVERSION RATE, OR WITH RESPECT TO THE NATURE OR
EXTENT OR CALCULATION OF ANY SUCH ADJUSTMENT WHEN MADE, OR WITH RESPECT TO THE
METHOD EMPLOYED, OR HEREIN OR IN ANY SUPPLEMENTAL INDENTURE PROVIDED TO BE
EMPLOYED, IN MAKING THE SAME.  THE TRUSTEE AND ANY OTHER CONVERSION AGENT SHALL
NOT BE ACCOUNTABLE WITH RESPECT TO THE VALIDITY OR VALUE (OR THE KIND OR AMOUNT)
OF ANY SHARES OF COMMON STOCK, OR OF ANY CAPITAL STOCK, OTHER SECURITIES OR
OTHER ASSETS OR PROPERTY, WHICH MAY AT ANY TIME BE ISSUED OR DELIVERED UPON THE
CONVERSION OF ANY NOTE; AND THE TRUSTEE AND ANY OTHER CONVERSION AGENT MAKE NO
REPRESENTATIONS WITH RESPECT THERETO.  NEITHER THE TRUSTEE NOR ANY CONVERSION
AGENT SHALL BE RESPONSIBLE FOR ANY FAILURE OF THE ISSUER TO ISSUE, TRANSFER OR
DELIVER ANY SHARES OF COMMON STOCK OR STOCK CERTIFICATES OR OTHER SECURITIES OR
PROPERTY OR CASH UPON THE SURRENDER OF ANY NOTE FOR THE PURPOSE OF CONVERSION OR
TO COMPLY WITH ANY OF THE DUTIES, RESPONSIBILITIES OR COVENANTS OF THE ISSUER
CONTAINED IN THIS ARTICLE 13.  WITHOUT LIMITING THE GENERALITY OF THE FOREGOING,
NEITHER THE TRUSTEE NOR ANY CONVERSION AGENT SHALL BE UNDER ANY RESPONSIBILITY
TO DETERMINE THE CORRECTNESS OF ANY PROVISIONS CONTAINED IN ANY SUPPLEMENTAL
INDENTURE ENTERED INTO PURSUANT TO SECTION 13.06 RELATING EITHER TO THE KIND OR
AMOUNT OF SHARES OF CAPITAL STOCK OR OTHER SECURITIES OR OTHER ASSETS OR
PROPERTY (INCLUDING CASH) RECEIVABLE BY NOTEHOLDERS UPON THE CONVERSION OF THEIR
NOTES AFTER ANY EVENT REFERRED TO IN SUCH SECTION 13.06 OR TO ANY ADJUSTMENT TO
BE MADE WITH RESPECT THERETO, BUT, SUBJECT TO THE PROVISIONS OF SECTION 7.01,
MAY ACCEPT AS CONCLUSIVE EVIDENCE OF THE CORRECTNESS OF ANY SUCH PROVISIONS, AND
SHALL BE PROTECTED IN RELYING UPON, THE OFFICERS’ CERTIFICATE (WHICH THE ISSUER
SHALL BE OBLIGATED TO FILE WITH THE TRUSTEE PRIOR TO THE EXECUTION OF ANY SUCH
SUPPLEMENTAL INDENTURE) WITH RESPECT THERETO. THE TRUSTEE SHALL NOT AT ANY TIME
BE UNDER ANY DUTY OR RESPONSIBILITY TO ANY HOLDER OF NOTES TO DETERMINE THE
ACCURACY OF THE METHOD EMPLOYED IN CALCULATING THE TRADING PRICE OR WHETHER ANY
FACTS EXIST WHICH MAY REQUIRE ANY ADJUSTMENT OF THE TRADING PRICE.

62

--------------------------------------------------------------------------------

SECTION 13.10.  NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  IN CASE:

(A)           THE ISSUER SHALL DECLARE A DIVIDEND (OR ANY OTHER DISTRIBUTION) ON
ITS COMMON STOCK THAT WOULD REQUIRE AN ADJUSTMENT IN THE CONVERSION RATE
PURSUANT TO SECTION 13.05; OR

(B)           THE ISSUER SHALL AUTHORIZE THE GRANTING TO THE HOLDERS OF ALL OR
SUBSTANTIALLY ALL OF ITS COMMON STOCK OF RIGHTS OR WARRANTS TO SUBSCRIBE FOR OR
PURCHASE ANY SHARE OF ANY CLASS OR ANY OTHER RIGHTS OR WARRANTS; OR

(C)           OF ANY RECLASSIFICATION OR REORGANIZATION OF THE COMMON STOCK
(OTHER THAN A SUBDIVISION OR COMBINATION OF ITS OUTSTANDING COMMON STOCK, OR A
CHANGE IN PAR VALUE, OR FROM PAR VALUE TO NO PAR VALUE, OR FROM NO PAR VALUE TO
PAR VALUE), OR OF ANY CONSOLIDATION, COMBINATION, MERGER OR SHARE EXCHANGE TO
WHICH THE ISSUER IS A PARTY AND FOR WHICH APPROVAL OF ANY STOCKHOLDERS OF THE
ISSUER IS REQUIRED, OR OF THE SALE OR TRANSFER OF ALL OR SUBSTANTIALLY ALL OF
THE ASSETS OF THE ISSUER; OR

(D)           OF THE VOLUNTARY OR INVOLUNTARY DISSOLUTION, LIQUIDATION OR
WINDING UP OF THE ISSUER;

the Issuer shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at its address appearing on the Note Register provided for in
Section 2.05 of this Indenture, as promptly as possible but in any event at
least ten (10) calendar days prior to the applicable date hereinafter specified,
a notice stating (x) the date on which a record is to be taken for the purpose
of such dividend, distribution or rights or warrants, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution or rights are to be determined, or (y)
the date on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up.  Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

SECTION 13.11.  STOCKHOLDER RIGHTS PLANS.  IF THE ISSUER HAS IN EFFECT A RIGHTS
PLAN WHILE ANY NOTES REMAIN OUTSTANDING, HOLDERS OF NOTES WILL RECEIVE, UPON A
CONVERSION OF NOTES IN RESPECT OF WHICH THE ISSUER IS REQUIRED TO DELIVER SHARES
OF COMMON STOCK, IN ADDITION TO SUCH SHARES OF COMMON STOCK, RIGHTS UNDER THE
ISSUER’S STOCKHOLDER RIGHTS AGREEMENT UNLESS, PRIOR TO CONVERSION, THE RIGHTS
HAVE EXPIRED, TERMINATED OR BEEN REDEEMED OR UNLESS THE RIGHTS HAVE SEPARATED
FROM THE COMMON STOCK. IF THE RIGHTS PROVIDED FOR IN THE RIGHTS PLAN ADOPTED BY
THE ISSUER HAVE SEPARATED FROM THE COMMON STOCK IN ACCORDANCE WITH THE
PROVISIONS OF THE APPLICABLE STOCKHOLDER RIGHTS AGREEMENT SO THAT HOLDERS OF
NOTES WOULD NOT BE ENTITLED TO RECEIVE ANY RIGHTS IN RESPECT OF COMMON STOCK, IF
ANY, THAT THE ISSUER IS REQUIRED TO DELIVER UPON CONVERSION OF NOTES, THE
CONVERSION RATE WILL BE ADJUSTED AT THE TIME OF SEPARATION AS IF THE ISSUER HAD
DISTRIBUTED TO ALL HOLDERS OF COMMON STOCK CAPITAL SHARES, EVIDENCES OF
INDEBTEDNESS OR OTHER ASSETS OR PROPERTY PURSUANT TO SECTION 13.05(C) ABOVE,
SUBJECT TO READJUSTMENT UPON THE SUBSEQUENT EXPIRATION, TERMINATION OR
REDEMPTION OF THE RIGHTS.

63

--------------------------------------------------------------------------------

SECTION 13.12.  SETTLEMENT UPON CONVERSION.

(A)           UPON A CONVERSION OF NOTES, THE ISSUER SHALL DELIVER, IN RESPECT
OF EACH $1,000 PRINCIPAL AMOUNT OF NOTES BEING CONVERTED, CASH AND SHARES OF
COMMON STOCK, IF ANY, EQUAL TO THE SUM OF THE DAILY SETTLEMENT AMOUNTS FOR EACH
OF THE 30 TRADING DAYS DURING THE OBSERVATION PERIOD.

(B)           THE “DAILY SETTLEMENT AMOUNT,” FOR EACH OF THE 30 TRADING DAYS
DURING THE OBSERVATION PERIOD, SHALL CONSIST OF:

(I)            CASH EQUAL TO THE LESSER OF (I) ONE-THIRTIETH OF $1,000 AND (II)
THE DAILY CONVERSION VALUE; AND

(II)           TO THE EXTENT THE DAILY CONVERSION VALUE EXCEEDS ONE-THIRTIETH OF
$1,000, A NUMBER OF SHARES OF COMMON STOCK EQUAL TO (I) THE DIFFERENCE BETWEEN
THE DAILY CONVERSION VALUE AND ONE-THIRTIETH OF $1,000, DIVIDED BY (II) THE
DAILY VWAP (DEFINED BELOW) FOR SUCH DAY.

“Daily Conversion Value” means, for each of the 30 consecutive Trading Days
during the Observation Period, one-thirtieth of the product of (i) the
applicable Conversion Rate and (ii) the Daily VWAP of the Common Stock on such
day.

“Daily VWAP” means, for each of the 30 consecutive Trading Days during the
Observation Period, the per share volume-weighted average price as displayed
under the heading “Bloomberg VWAP” on Bloomberg page “UDR.N <equity> AQR” (or
any successor thereto) in respect of the period from the scheduled open of the
primary exchange or market on which the Common Stock is listed or traded to the
scheduled close of such exchange or market on such Trading Day (or if such
volume-weighted average price is unavailable, the market value of one share of
Common Stock on such Trading Day determined, using a volume-weighted average
method, by a nationally recognized independent investment banking firm retained
for this purpose by the Issuer).

“Observation Period” with respect to any Note means the 30 consecutive Trading
Day period beginning on and including the second Trading Day after the
Conversion Date relating to such Note, except that with respect to any Note
surrendered for conversion during the period beginning on July 15, 2011 and
ending on the second Business Day prior to the Stated Maturity, “Observation
Period” means the first 30 Trading Days beginning on and including the 32nd
Scheduled Trading Day prior to the Stated Maturity.

For the purposes of determining payment upon conversion in accordance with the
provisions of this Section 13.12 only, “Trading Day” means a day on which (i)
there is no Market Disruption Event and (ii) trading in securities generally
occurs on the New York Stock Exchange or, if the Common Stock is not then listed
on the New York Stock Exchange, on the principal other United States national or
regional securities exchange on which the Common Stock is then listed or, if the
Common Stock is not then listed on a United States national or regional
securities exchange, in the principal other market on which the Common Stock is
then traded. If the Common Stock (or other security for which a Daily VWAP must
be determined) is not so listed or quoted, “Trading Day” means a “Business Day.”

64

--------------------------------------------------------------------------------

“Scheduled Trading Day” means a day that is scheduled to be a Trading Day.

“Market Disruption Event” means the occurrence or existence for more than one
half-hour period in the aggregate on any scheduled Trading Day for the Common
Stock of any suspension or limitation imposed on trading (by reason of movements
in price exceeding limits permitted by the New York Stock Exchange or otherwise)
in the Common Stock or in any options, contracts or future contracts relating to
the Common Stock, and such suspension or limitation occurs or exists at any time
before 1:00 p.m. (New York City time) on such day.

(C)           THE ISSUER SHALL DELIVER THE SUM OF THE DAILY SETTLEMENT AMOUNTS
FOR EACH OF THE 30 TRADING DAYS DURING THE OBSERVATION PERIOD TO CONVERTING
HOLDERS ON THE THIRD BUSINESS DAY IMMEDIATELY FOLLOWING THE LAST DAY OF THE
OBSERVATION PERIOD.

SECTION 13.13.  CONVERSION RATE ADJUSTMENT AFTER CERTAIN CHANGE IN CONTROL
TRANSACTIONS.

(A)           IF THE EFFECTIVE DATE OF A CHANGE IN CONTROL OCCURS PRIOR TO THE
STATED MATURITY AS A RESULT OF A TRANSACTION OR EVENT DESCRIBED IN CLAUSES (1)
OR (2) OF THE DEFINITION OF CHANGE IN CONTROL AND A HOLDER ELECTS TO CONVERT ITS
NOTES IN CONNECTION WITH SUCH CHANGE IN CONTROL PURSUANT TO SECTION 13.01(A)(IV)
HEREOF, THE ISSUER SHALL INCREASE THE APPLICABLE CONVERSION RATE FOR SUCH NOTES
SURRENDERED FOR CONVERSION BY A NUMBER OF ADDITIONAL SHARES OF COMMON STOCK (THE
“ADDITIONAL SHARES”) AS SPECIFIED BELOW.  A CONVERSION OF NOTES WILL BE DEEMED
FOR THESE PURPOSES TO BE “IN CONNECTION WITH” SUCH A CHANGE IN CONTROL IF THE
CONVERSION NOTICE IS RECEIVED BY THE CONVERSION AGENT ON ANY DATE FROM AND
INCLUDING THE DATE THAT IS THE EFFECTIVE DATE OF SUCH CHANGE IN CONTROL UP TO
AND INCLUDING THE EARLIER OF THE 30TH BUSINESS DAY FOLLOWING THE EFFECTIVE DATE
OF SUCH CHANGE IN CONTROL AND THE SECOND BUSINESS DAY PRECEDING THE STATED
MATURITY.

(B)           THE NUMBER OF ADDITIONAL SHARES WILL BE DETERMINED BY REFERENCE TO
THE TABLE IN SECTION 13.13(E) AND IS BASED ON THE DATE ON WHICH THE CHANGE IN
CONTROL BECOMES EFFECTIVE (THE “EFFECTIVE DATE”) AND THE PRICE PAID PER SHARE OF
COMMON STOCK IN THE CHANGE IN CONTROL TRANSACTION (THE “STOCK PRICE”).  IF
HOLDERS OF COMMON STOCK RECEIVE ONLY CASH IN THE CHANGE IN CONTROL TRANSACTION,
THE STOCK PRICE SHALL EQUAL THE CASH AMOUNT PAID PER SHARE OF COMMON STOCK IN
SUCH TRANSACTION.  IN ALL OTHER CASES, THE STOCK PRICE SHALL EQUAL THE AVERAGE
OF THE CLOSING SALE PRICES OF THE COMMON STOCK ON THE TEN (10) CONSECUTIVE
TRADING DAYS UP TO BUT EXCLUDING THE EFFECTIVE DATE.

(C)           THE STOCK PRICES SET FORTH IN THE FIRST ROW OF THE TABLE SET FORTH
IN SECTION 13.13(E) (I.E., THE COLUMN HEADERS) SHALL BE ADJUSTED AS OF ANY DATE
ON WHICH THE CONVERSION RATE OF THE NOTES IS ADJUSTED PURSUANT TO SECTION
13.05.  THE ADJUSTED STOCK PRICES SHALL EQUAL THE STOCK PRICES APPLICABLE
IMMEDIATELY PRIOR TO SUCH ADJUSTMENT MULTIPLIED BY A FRACTION, (I) THE NUMERATOR
OF WHICH SHALL BE THE CONVERSION RATE IMMEDIATELY PRIOR TO THE ADJUSTMENT GIVING
RISE TO THE STOCK PRICE ADJUSTMENT AND (II) THE DENOMINATOR OF WHICH SHALL BE
THE CONVERSION RATE AS SO ADJUSTED.

(D)           THE NUMBER OF ADDITIONAL SHARES SHALL BE ADJUSTED IN THE SAME
MANNER AND FOR THE SAME EVENTS AS THE CONVERSION RATE IS ADJUSTED PURSUANT TO
SECTION 13.05.

FORM OF REVERSE OF NOTE

UNITED DOMINION REALTY TRUST, INC.
3.625% CONVERTIBLE SENIOR NOTES DUE 2011

This note is one of a duly authorized issue of notes of the Issuer, designated
as its “3.625% Convertible Senior Notes due 2011” (herein called the “Notes”),
issued under and pursuant to an Indenture, dated as of October 12, 2006 (herein
called the “Indenture”), between the Issuer and U.S. Bank National Association,
as trustee (herein called the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the holders of the Notes.  Capitalized terms used but
not otherwise defined in this Note shall have the respective meanings ascribed
thereto in the Indenture.

The Issuer shall have the right to redeem the Notes at its option in accordance
with the provisions of Article 3 of the Indenture in order to preserve its
status as a real estate investment trust.  If the Issuer determines it is
necessary to redeem the Notes in order to preserve its status as a real estate
investment trust, the Issuer may redeem the Notes for cash, in whole or in part,
at a redemption price equal to 100% of the principal amount of the Notes to be
redeemed plus unpaid interest, if any, accrued thereon to the Redemption Date. 
In accordance with the provisions of the Indenture, the Issuer may not otherwise
redeem the Notes at its option prior to the Stated Maturity thereof.

Subject to the terms and conditions set forth in the Indenture, following the
occurrence of a Change in Control at any time prior to the Stated Maturity of
the Notes, the Notes shall be subject to repurchase by the Issuer, at the option
of the holder, on the Change in Control Repurchase Date, at a Change in Control
Purchase Price equal to 100% of the principal amount of the Notes to be
repurchased together with accrued and unpaid interest accrued thereon to the
Change in Control Repurchase Date.  To exercise such right, the holder shall be
required to satisfy the conditions to such repurchase set forth in the Indenture
and to deliver to the Paying Agent the Repurchase Notice set forth on the
reverse hereof prior to the close of business on the third Business Day prior to
the Change in Control Repurchase Date.

The Issuer may not repurchase any Notes if there has occurred and is continuing
an Event of Default with respect to the Notes (other than a default in the
payment of the Change in Control Purchase Price for such Notes).

HOLDERS HAVE THE RIGHT TO WITHDRAW ANY REPURCHASE NOTICE BY DELIVERING TO THE
PAYING AGENT A WRITTEN NOTICE OF WITHDRAWAL AT ANY TIME PRIOR TO THE CLOSE OF
BUSINESS ON THE THIRD BUSINESS DAY PRIOR TO THE CHANGE IN CONTROL REPURCHASE
DATE, ALL AS PROVIDED IN THE INDENTURE.

Subject to and in compliance with the provisions of the Indenture, holders of
Notes shall have the right to convert each $1,000 principal amount of Notes at
the applicable Conversion Rate into the consideration specified in the
Indenture, upon surrender of the Note to be converted with the form entitled
“Conversion Notice” on the reverse hereof duly completed and manually signed, to
the Issuer at the office or agency of the Issuer maintained for that purpose in
The City of New York in accordance with the terms of the Indenture, together
with any funds required

A-6

--------------------------------------------------------------------------------

pursuant to the terms of the Indenture.  The Conversion Rate shall initially be
26.6326 shares of Common Stock per $1,000 principal amount of Notes, subject to
adjustment in the manner set forth in the Indenture.

Notes surrendered for conversion at any time after the close of business on any
applicable Record Date for the payment of interest and on or prior to the
corresponding Interest Payment Date must be accompanied by payment, in
immediately available funds or other funds acceptable to the Issuer, of an
amount equal to the interest otherwise payable on such Interest Payment Date on
the principal amount being converted; provided  that no such payment shall be
required (1) if the Issuer has specified a Redemption Date that is after a
Record Date and on or prior to the corresponding Interest Payment Date, (2) to
the extent of any overdue interest and Additional Interest, if any overdue
interest and Additional Interest, as applicable, exists at the time of
conversion with respect to such Notes, or (3) in respect of any conversion that
occurs after the Record Date for the interest payment due on September 15, 2011.

In the event the holder surrenders this Note for conversion in connection with a
Change in Control resulting from a transaction described in clause (1) or (2) of
the definition of such term, the Issuer shall increase the applicable Conversion
Rate in accordance with the provisions of Section 13.13 of the Indenture.

In the event that shares of Common Stock are issued upon conversion of Notes, no
fractional shares shall be issued upon such conversion, but an adjustment and
payment in cash will be made, as provided in the Indenture, in respect of any
fraction of a share which would otherwise be issuable upon such conversion.

A Note in respect of which a holder has submitted a Repurchase Notice may be
converted only if such holder validly withdraws such Repurchase Notice in
accordance with the terms of the Indenture.

If an Event of Default (other than an Event of Default specified in Section
6.01(h), 6.01(i) and 6.01(j) of the Indenture) with respect to the Issuer) shall
occur and be continuing, the principal of, and accrued and unpaid interest on,
the Notes may be declared to be due and payable in the manner specified in the
Indenture.  If an Event of Default specified in Section 6.01(h), 6.01(i) or
6.01(j) of the Indenture shall occur with respect to the Issuer, the principal
of, and interest accrued and unpaid on, the Notes shall be immediately and
automatically due and payable without necessity of further action. Subject to
the provisions of the Indenture, the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding may, on behalf
of the holders of all of the Notes, waive any past default or Event of Default,
subject to exceptions set forth in the Indenture.  Upon any such waiver, said
default shall for all purposes of this Note and the Indenture be deemed to have
been cured and to be not continuing, but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

The Indenture contains provisions permitting the Issuer and the Trustee, with
the consent of the holders of not less than a majority in aggregate principal
amount of the Notes at the time outstanding, to execute supplemental indentures
to modify provisions of the Indenture, subject to exceptions permitting the
modification of the Indenture without the consent of any holder of

A-7

--------------------------------------------------------------------------------

Notes or requiring the consent of each holder of a Note affected by such
modification all as set forth in Article 9 of the Indenture.

The Notes are issuable in fully registered form, without coupons, in
denominations of $1,000 principal amount and any multiple of $1,000.  At the
office or agency of the Issuer referred to on the face hereof, and in the manner
and subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate
principal amount of Notes of any other authorized denominations. Upon surrender
for registration of transfer of any Note to the Note Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth
in the Indenture, the Issuer shall execute, and the Trustee shall authenticate
and deliver, in the name of the designated transferee or transferees, one or
more new Notes of any authorized denominations and of a like aggregate principal
amount and bearing such restrictive legends as may be required by the
Indenture.  No service charge shall be made to any holder for any registration
of transfer or exchange of Notes, but the Issuer may require payment by the
holder of a sum sufficient to cover any tax, assessment or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Notes.

The Issuer, the Trustee, any Paying Agent, any Conversion Agent and any Note
Registrar may deem the Person in whose name this Note shall be registered upon
the Note Register to be, and may treat it as, the absolute owner of this Note
(whether or not this Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon made by any Person other than the Issuer or
any Note Registrar) for the purpose of receiving payment of or on account of the
principal of, and interest on this Note, for conversion of this Note and for all
other purposes; and neither the Issuer or the Trustee nor any Paying Agent,
Conversion Agent or any Note Registrar shall be affected by any notice to the
contrary.  All such payments so made to any holder for the time being, or upon
its order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any
this Note.

No recourse for the payment of the principal of or interest on this Note, or for
any claim based hereon or otherwise in respect hereof, and no recourse under or
upon any obligation, covenant or agreement of the Issuer in the Indenture or any
supplemental indenture or in any Note, or because of the creation of any
indebtedness represented hereby, shall be had against any incorporator,
stockholder, partner, member, manager, employee, agent, officer, director or
subsidiary, as such, past, present or future, of the Issuer or any of the
Issuer’s Subsidiaries or of any successor thereto, either directly or through
the Issuer or any of the Issuer’s Subsidiaries or of any successor thereto,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as consideration for, the execution of the Indenture and the
issue of this Note.

In the case of any conflict between the provisions of this Note and the
Indenture, the provisions of the Indenture shall control. The Indenture and this
Note shall be governed by, and construed in accordance with, the laws of the
state of New York.
