ARTICLE 2

Issue, Description, Execution, Registration and Exchange of Notes

     Section 2.01. Designation Amount and Issue of Notes. The Notes shall be designated as the
“4.00% Convertible Senior Notes due 2035.” 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 $200,000,000 (or $250,000,000 if the Initial Purchaser’s option
set forth in the Purchase Agreement is exercised in full). The Issuer may, without the consent of
the holders of Notes, issue additional Notes (the “Additional Notes”) from time to time in the
future with the same terms and 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 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

9

 

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 comprised of twelve
30-day months.

     The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register
at 5:00 p.m., 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 Maturity Date 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, a
Fundamental Change Repurchase Date or a 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. 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 June 1 or the December 1 next preceding the applicable Interest Payment
Date.

     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

10

 

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 5:00 p.m., 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 (10) 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 5:00 p.m., 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.

     (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.

11

 

     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, 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.

12

 

     In connection with the redemption of the Notes in part, neither the Issuer nor the Trustee nor
any Note Registrar shall be required to issue or register the transfer or exchange of (a) any Notes
for a period of fifteen (15) calendar days next preceding any selection of Notes to be redeemed and
ending at the close of business on the earliest date on which the relevant notice of redemption is
deemed to have been given to all holders of Notes to be so redeemed, 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.

     (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.

13

 

     (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 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 IS ELIGIBLE FOR RESALE UNDER RULE 144A UNDER THE SECURITIES ACT, TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A THEREUNDER, (C) PURSUANT TO ANY OTHER AVAILABLE
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING THE EXEMPTION PROVIDED BY RULE 144
THEREUNDER (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
TRANSFER; AND

     (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS
TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE
EFFECT OF THIS LEGEND.

IN CONNECTION WITH ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY WITHIN TWO YEARS AFTER THE
ORIGINAL ISSUANCE OF SUCH SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE), THE
HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF
SUCH TRANSFER AND SUBMIT THIS CERTIFICATE 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 THE ISSUER 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 THE SECURITY EVIDENCED HEREBY PURSUANT TO CLAUSE 2(D) ABOVE OR THE EXPIRATION OF
TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY.

15

 

     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 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

16

 

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 Repurchase Date or a Fundamental Change 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 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

17

 

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 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 not have the right to redeem
any Notes prior to January 15, 2011, except to preserve its status as a real estate

18

 

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, but excluding, 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.

     The Issuer shall have the right to redeem the Notes for cash, in whole or in part at any time
or from time to time, on or after January 15, 2011 upon the notice set forth in Section 3.02, 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, but excluding, the Redemption Date.

     In connection with any redemption in accordance with the provisions of this Section 3.01, if
an Interest Payment Date falls on or prior to the Redemption Date, then the interest payable on
such Interest Payment Date shall be paid to the holders of record of the Notes on the applicable
Record Date instead of the holders surrendering the Notes for redemption.

     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 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, but excluding, 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

19

 

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, but excluding,
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, but excluding, 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) by lot, 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 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

20

 

notice at the redemption price, plus interest accrued to, but excluding, 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, but excluding, 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, but excluding, 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 Fundamental Change.

     (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, 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
“Fundamental Change Repurchase Date”) specified by the Issuer (which date shall be not more than
thirty (30) Business Days after the Issuer Repurchase Notice Date related to such Fundamental
Change) at a repurchase price equal to 100% of the principal amount of the Notes being repurchased,
plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date;
provided that if an Interest Payment Date falls on or prior to the Fundamental Change Repurchase
Date, then, with respect to any Note in respect of which the holder thereof shall have submitted a
Repurchase Notice, the interest payable on such Interest Payment Date shall be paid to the holder
of record of such Note on the applicable Record Date instead of the holder surrendering such Note
for repurchase on such Fundamental Change Repurchase Date.

     (b) Within 10 days after the occurrence of a Fundamental Change, the Issuer shall mail or
cause to be mailed to all holders of record on the date of the Fundamental Change (and to
beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in
Section 3.07 with respect to such Fundamental Change. 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 news organization announcing the occurrence of such Fundamental Change and
publish such information in a newspaper of general circulation in The City of New

21

 

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 Fundamental Change 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 repurchase 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 repurchase 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 repurchase price shall be paid to
such holder, subject to receipt of funds and/or Notes by the Paying Agent, within two (2) Business
Days following the later of (x) the Fundamental Change Repurchase Date with respect to such Note
(provided the holder has satisfied the conditions in this Section 3.05) and (y) the time of
book-entry transfer or delivery of such Note or beneficial interest therein to the Paying Agent by
the holder thereof.

22

 

     Section 3.06. Repurchase of Notes at the Option of Holders.

     (a) Noteholders shall have the right to require the Issuer to repurchase their Notes for cash,
in whole or in part (in principal amounts of $1,000 and integral multiples thereof) on January 15,
2011, December 15, 2015, December 15, 2020, December 15, 2025 and December 15, 2030 (each, a
“Repurchase Date”), at a repurchase price equal to 100% of the principal amount of the Notes being
repurchased, plus accrued and unpaid interest to, but excluding, the Repurchase Date; provided that
if an Interest Payment Date falls on or prior to the Repurchase Date, then, with respect to any
Note in respect of which the holder thereof shall have submitted a Repurchase Notice, the interest
payable on such Interest Payment Date shall be paid to the holder of record of such Note on the
applicable Record Date instead of the holder surrendering such Note for repurchase on such
Repurchase Date.

     (b) On or before the twentieth (20th) Business Day immediately preceding each Repurchase Date,
the Issuer shall mail or cause to be mailed to all holders of record on such date (and to
beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in
Section 3.07. 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 news organization containing the
information specified in such notice and publish such information in a newspaper of general
circulation in The City of New York, on the Issuer’s web site, or through such other public medium
as the Issuer shall deem appropriate at such time.

     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 3.06.

     (c) In order to exercise the repurchase right, the holder must deliver a Repurchase Notice to
the Paying Agent, during the period beginning at the opening of business on the date that is twenty
(20) Business Days prior to the applicable Repurchase Date and ending at the close of business on
the applicable Repurchase Date. 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 as of the Repurchase Date 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 3.06, 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 3.06 if there has occurred and is continuing an Event of Default with

23

 

respect to the Notes (other than a default in the payment of the repurchase 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 repurchase 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 repurchase price shall be paid to
such holder, subject to receipt of funds and/or Notes by the Paying Agent, within two (2) Business
Days following the later of (x) the Repurchase Date with respect to such Note (provided the holder
has satisfied the conditions in this Section 3.06) and (y) the time of book-entry transfer or
delivery of such Note or beneficial interest therein to the Paying Agent by the holder thereof.

     Section 3.07. Issuer Repurchase Notice.

     (a) In connection with any repurchase of Notes, the Issuer shall, on the applicable Issuer
Repurchase Notice Date, give written notice to holders (with a copy to the Trustee) setting forth
the information specified in this Section (in either case, the “Issuer Repurchase Notice”).

     Each Issuer Repurchase Notice shall:

     (1) state the repurchase price and the amount of interest accrued and unpaid per $1,000
principal amount of Notes to, but excluding, the Fundamental Change Repurchase Date or the
Repurchase Date, as the case may be;

     (2) the Fundamental Change Repurchase Date or the Repurchase Date, as the case may be;

     (3) state, if applicable, the circumstances constituting the Fundamental Change;

     (4) state that holders must exercise their right to elect to repurchase prior to the close of
business on the Repurchase Date or Fundamental Change Repurchase Date, as the case may be;

     (5) include a form of Repurchase Notice;

Indenture;

     (10) state that, unless the Issuer defaults in making payment of the repurchase price,

deposited on the Fundamental Change Repurchase Date or the Repurchase Date, as the case may be),
sufficient to pay the aggregate repurchase price of all the Notes or portions thereof that are to
be repurchased as of the Fundamental Change Repurchase Date or the Repurchase Date, as the case may
be.

     (b) If on the Fundamental Change Repurchase Date or the Repurchase Date the Paying Agent holds
money sufficient to pay the repurchase price of the Notes that holders have elected to require the
Issuer to repurchase in accordance with Section 3.05 or 3.06, as the case may be, then, on the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be, such Notes will
cease to be outstanding, interest will cease to accrue and all other rights of the holders of such
Notes will terminate, other than the right to receive the repurchase price. Such will be the case
whether or not book-entry transfer of the Note to the Paying Agent is made or whether or not Notes
in certificated form, together with necessary endorsements, are delivered to the Paying Agent.

presented.

     Section 3.11. Repayment to the Issuer. Subject to Section 11.04, the Paying Agent shall
return to the Issuer any cash that remains unclaimed, together with interest, if any, thereon, held

amount of cash deposited by the Issuer pursuant to Section 3.09 exceeds the aggregate repurchase
price of the Notes or portions thereof which the Issuer is obligated to repurchase as of the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be, then, unless
otherwise agreed in writing with the Issuer, promptly after the second Business Day following the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be, the Paying Agent
shall return any such excess to the Issuer, together with interest, if any, thereon.

agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations. The Issuer will give prompt written notice to the Trustee
of any such designation or rescission and of any change in the location of any such other office or
agency.

     The Issuer hereby initially designates the Trustee as Paying Agent, Note Registrar, Custodian,
Conversion Agent and Bid Solicitation Agent and the Corporate Trust Office shall be considered as
one such office or agency of the Issuer for each of the aforesaid purposes.

mailed, the notices set forth in Section 7.10(a) and the third paragraph of Section 7.11. If
co-registrars have been appointed in accordance with this Section, the Trustee shall mail such
notices only to the Issuer and the holders of Notes it can identify from its records.

     Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Issuer, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, upon the terms and
conditions and otherwise as provided in Section 7.10, a Trustee, so that there shall at all times
be a Trustee hereunder.

     Section 4.04. Provisions as to Paying Agent.

     (a) If the Issuer shall appoint a Paying Agent other than the Trustee, or if the Trustee shall
appoint such a Paying Agent, the Issuer will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions
of this Section 4.04:

     (1) that it will hold all sums held by it as such agent for the payment of the
principal of, or interest on, the Notes (whether such sums have been paid to it by the
Issuer or by any other obligor on the Notes) in trust for the benefit of the holders of the
Notes;

     (2) that it will give the Trustee notice of any failure by the Issuer (or by any other
obligor on the Notes) to make any payment of the principal of, or interest on, the Notes
when the same shall be due and payable; and

27

 

     (3) that at any time during the continuance of an Event of Default, upon request of the
Trustee, it will forthwith pay to the Trustee all sums so held in trust.

     The Issuer shall, on or before each due date of the principal of, or interest on, the Notes,
deposit with the Paying Agent a sum (in funds which are immediately available on the due date for
such payment) sufficient to pay such principal, or interest and (unless such Paying Agent is the
Trustee) the Issuer will promptly notify the Trustee of any failure to take such action; provided
that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by
11:00 a.m. New York City time, on such date.

     (b) If the Issuer shall act as its own Paying Agent, it will, on or before each due date of
the principal of, or interest on, the Notes, set aside, segregate and hold in trust for the benefit
of the holders of the Notes a sum sufficient to pay such principal and interest so becoming due and
will promptly notify the Trustee of any failure to take such action and of any failure by the
Issuer (or any other obligor under the Notes) to make any payment of the principal of, or interest
on, the Notes when the same shall become due and payable.

     (c) Anything in this Section 4.04 to the contrary notwithstanding, the Issuer may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Issuer or any Paying
Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Issuer or any Paying Agent to the Trustee, the
Issuer or such Paying Agent shall be released from all further liability with respect to such sums.

     (d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 4.04 is subject to Section 11.02 and Section 11.03.

     The Trustee shall not be responsible for the actions of any other Paying Agents (including the
Issuer if acting as its own Paying Agent) and shall have no control of any funds held by such other
Paying Agents.

     Section 4.05. Existence. Subject to Article 10, the Issuer will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and rights (charter
and statutory); provided that the Issuer shall not be required to preserve any such right if the
Issuer shall determine that the preservation thereof is no longer desirable in the conduct of its
business and that the loss thereof is not disadvantageous in any material respect to the
Noteholders.

     Section 4.07. Rule 144A Information Requirement. Within the period prior to the expiration
of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or
any successor provision), the Issuer covenants and agrees that it shall, during any period in which
it is not subject to Section 13 or 15(d) under the Exchange Act, make available to any holder or
beneficial holder of Notes or any shares of Common Stock issued upon conversion thereof which
continue to be Restricted Securities in connection with any sale thereof and any prospective
purchaser of Notes or such shares of Common Stock designated by such holder or beneficial holder,
the information required pursuant to Rule 144A(d)(4) under the

28

 

Securities Act upon the request of any holder or beneficial holder of the Notes or such shares
of Common Stock, all to the extent required to enable such holder or beneficial holder to sell its
Notes or shares of Common Stock without registration under the Securities Act within the limitation
of the exemption provided by Rule 144A.

     Section 4.08. Stay, Extension and Usury Laws. The Issuer covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or other law which
would prohibit or forgive the Issuer from paying all or any portion of the principal, premium, if
any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this Indenture and the
Issuer (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution
of every such power as though no such law had been enacted.

     Section 4.09. Compliance Certificate. The Issuer shall deliver to the Trustee, within one
hundred twenty (120) calendar days after the end of each fiscal year of the Issuer, a certificate
signed by any of the principal executive officer, principal financial officer or principal
accounting officer of the Issuer, stating whether or not to the knowledge of the signer thereof the
Issuer is in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Issuer shall be in default, specifying all such defaults and the
nature and the status thereof of which the signer may have knowledge.

     The Issuer will deliver to the Trustee, promptly upon becoming aware of (i) any default in the
performance or observance of any covenant, agreement or condition contained in this Indenture, or
(ii) any Event of Default, an Officers’ Certificate specifying with particularity such default or
Event of Default and further stating what action the Issuer has taken, is taking or proposes to
take with respect thereto.

     Any notice required to be given under this Section 4.09 shall be delivered to a Responsible
Officer of the Trustee at its Corporate Trust Office.

     Section 4.10. Additional Interest Notice. In the event that the Issuer is required to pay
Additional Interest to holders of Notes pursuant to the Registration Rights Agreement, the Issuer
will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay
Additional Interest no later than fifteen (15) calendar days prior to the proposed payment date for
Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional
Interest to be paid by the Issuer on such payment date. The Trustee shall not at any time be under
any duty or responsibility to any holder of Notes to determine the Additional Interest, or with
respect to the nature, extent or calculation of the amount of Additional Interest when made, or
with respect to the method employed in such calculation of the Additional Interest.

the Trustee may reasonably request in writing, within thirty (30) calendar days after receipt by
the Issuer of any such request (or such lesser time as the Trustee may reasonably request in order
to enable it to timely provide any notice to be provided by it hereunder), a list in such form as
the Trustee may reasonably require of the names and addresses of the holders of Notes as of a date

that no such list need be furnished by the Issuer to the Trustee so long as the Trustee is acting
as the sole Note Registrar.

     Section 5.02. Preservation and Disclosure of Lists.

     (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Notes contained in the most recent list

Registrar or co-registrar in respect of the Notes, if so acting. The Trustee may destroy any list
furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

     (b) The rights of Noteholders to communicate with other holders of Notes with respect to their
rights under this Indenture or under the Notes, and the corresponding rights and duties of the
Trustee, shall be as provided by the Trust Indenture Act.

     (c) Every Noteholder agrees with the Issuer and the Trustee that neither the Issuer nor the
Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of
information as to names and addresses of holders of Notes made pursuant to the Trust Indenture Act.

of the Exchange Act and for so long as any Notes are outstanding, within the time periods

30

Commission on Forms 10-Q and 10-K if the Issuer were required to file such reports; and (2) all
current reports that would be required to be filed with the Commission on Form 8-K if the Issuer
were required to file such reports. Delivery of such reports, information and documents to the

constructive notice of any information contained therein or determinable from information contained
therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the

31

 

or acceleration has not been cured or rescinded, prior to written notice of such failure to
the Issuer by the Trustee or to the Issuer and the Trustee by holders of not less than ten percent
(10%) in aggregate principal amount of the Notes outstanding; or

     (g) failure by the Issuer or any of its Subsidiaries to pay final judgments entered by a court

final and non-appealable; or

     (h) the Issuer or any Significant Subsidiary of the Issuer pursuant to or under or within
meaning of any Bankruptcy Law:

its property; or

     (ii) consents to any such relief or to the appointment of or taking possession by any

its property; or

     (iv) makes a general assignment for the benefit of creditors; or

     (i) an involuntary case or other proceeding shall be commenced against the Issuer or any
Significant Subsidiary of the Issuer seeking liquidation, reorganization or other relief with
respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter
in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar

32

 

     If an Event of Default (other than an Event of Default specified in Section 6.01(h), 6.01(i)
and 6.01(j)) with respect to the Issuer) shall occur and be continuing, unless the principal of all
of the Notes shall have already become due and payable, either the Trustee or the holders of at
least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding, by
notice in writing to the Issuer (and to the Trustee if given by Noteholders), may declare the
principal of, and interest (including Additional Interest, if any) accrued and unpaid on, all the
Notes to be immediately due and payable, and upon any such declaration the same shall be
immediately due and payable.

     If an Event of Default specified in Section 6.01(h), 6.01(i) or 6.01(j) occurs with respect to
the Issuer, the principal of, and interest (including Additional Interest, if any) accrued and
unpaid on, all the Notes shall be immediately and automatically due and payable without necessity
of further action.

     If, at any time after the principal of and interest on the Notes shall have been so declared
due and payable, and before any judgment or decree for the payment of the monies due shall have
been obtained or entered as hereinafter provided, holders of a majority in aggregate principal
amount of the Notes then outstanding on behalf of the holders of all of the Notes then outstanding,
by written notice to the Issuer and to the Trustee, may waive all defaults or Events of Default and
rescind and annul such declaration and its consequences subject to Section 6.07 if: (a) such
rescission would not conflict with any judgment or decree of a court of competent jurisdiction; (b)
interest on overdue installments of interest (including Additional Interest) (to the extent that
payment of such interest is lawful) and on overdue principal, which has become due otherwise than
by such declaration of acceleration, has been paid; (c) the Issuer has paid the Trustee its
reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances
pursuant to Section 7.06; and (d) all Events of Default, other than the nonpayment of the principal
amount and any accrued and unpaid interest that has become due solely because of such acceleration,
have been cured or waived. No such rescission and annulment shall extend to or shall affect any
subsequent default or Event of Default, or shall impair any right consequent thereon. The Issuer
shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof,
of any Event of Default, as provided in Section 4.09.

     In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and
annulment or for any other reason or shall have been determined adversely to the Trustee, then and
in every such case the Issuer, the holders of Notes, and the Trustee shall be restored respectively
to their several positions and rights hereunder, and all rights, remedies and powers of the Issuer,
the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken.

     Section 6.02. Payments of Notes on Default; Suit Therefor. The Issuer covenants that in the
case of an Event of Default pursuant to Section 6.01(a) or 6.01(b), upon demand of the Trustee, the
Issuer will pay to the Trustee, for the benefit of the holders of the Notes, (i) the whole amount
that then shall be due and payable on all such Notes for principal or interest, as the case may be,
with interest upon the overdue principal and premium, if any, and (to the extent that payment of
such interest is enforceable under applicable law) upon the overdue installments of accrued and
unpaid interest at the rate borne by the Notes, plus 1%, from the required payment

33

 

date and, (ii) in addition thereto, any amounts due the Trustee under Section 7.06. Until
such demand by the Trustee, the Issuer may pay the principal of and interest on the Notes to the
registered holders, whether or not the Notes are overdue.

     In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and
may prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or any other obligor on the Notes and collect in the
manner provided by law out of the property of the Issuer or any other obligor on the Notes wherever
situated the monies adjudged or decreed to be payable.

     In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Issuer or any other obligor on the Notes under any Bankruptcy Law, or any other applicable law, or
in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator
or similar 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 of any other judicial
proceedings relative to the Issuer or such other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of
the Notes shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this
Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest
in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and of the Noteholders allowed in such judicial proceedings relative to the Issuer or any
other obligor on the Notes, its or their creditors, or its or their property, and to collect and
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 in liquidation or under any
plan of reorganization or arrangement or otherwise.

     All rights of action and of asserting claims under this Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or

34

 

proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the holders of the Notes.

     In any proceedings brought by the Trustee (and in any proceedings involving the interpretation
of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be
held to represent all the holders of the Notes, and it shall not be necessary to make any holders
of the Notes parties to any such proceedings.

     Section 6.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee
pursuant to this Article 6, shall be applied, in the following order, at the date or dates fixed by
the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 7.06;

     SECOND: In case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of accrued and unpaid interest, if any, on the Notes in default in the order
of the maturity of the installments of such interest, with interest (to the extent that such
interest has been collected by the Trustee) as provided in Section 6.02 upon the overdue
installments of interest at the annual rate borne by the Notes plus 1%, such payments to be made
ratably to the Persons entitled thereto;

     THIRD: In case the principal of the outstanding Notes shall have become due, by declaration or
otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the Notes
for principal and interest, with interest on the overdue principal and (to the extent that such
interest has been collected by the Trustee) upon overdue installments of accrued and unpaid
interest, as provided in Section 6.02, and in case such monies shall be insufficient to pay in full
the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and
interest without preference or priority of principal over interest, or of interest over principal,
or of any installment of interest over any other installment of interest, or of any Note over any
other Note, ratably to the aggregate of such principal and accrued and unpaid interest; and

     FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully
entitled thereto.

     Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue
of or by reference to any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, except in the case of a default in the payment of principal of, or interest on, the
Notes, unless (a) such holder previously shall have given to the Trustee written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, (b) the holders of at least
twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding

35

 

shall have made written request upon the Trustee to institute such action, suit or proceeding
in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable security
or indemnity as it may require against the costs, liabilities or expenses to be incurred therein or
thereby, (c) the Trustee for sixty (60) calendar days after its receipt of such notice, request and
offer of indemnity, shall have neglected or refused to institute any such action, suit or
proceeding and (d) no direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 6.07; it being understood and intended, and being expressly covenanted
by the taker and holder of every Note with every other taker and holder and the Trustee, that no
one or more holders of Notes shall have any right in any manner whatever by virtue of or by
reference to any provision of this Indenture to affect, disturb or prejudice the rights of any
other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such
holder, or to enforce any right under this Indenture, except in the manner herein provided and for
the equal, ratable and common benefit of all holders of Notes (except as otherwise provided
herein). For the protection and enforcement of this Section 6.04, each and every Noteholder and
the Trustee shall be entitled to such relief as can be given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any holder of any Note to receive payment of the principal of (including the redemption price or
repurchase price upon redemption or repurchase pursuant to Article 3) and accrued interest on such
Note, on or after the respective due dates expressed in such Note or in the event of redemption or
repurchase, or to institute suit for the enforcement of any such payment on or after such
respective dates against the Issuer shall not be impaired or affected without the consent of such
holder.

     Anything contained in this Indenture or the Notes to the contrary notwithstanding, the holder
of any Note, without the consent of either the Trustee or the holder of any other Note, in its own
behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable
to enforce, its rights of conversion as provided herein.

     Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its
discretion, proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

     Section 6.06. Remedies Cumulative and Continuing. All powers and remedies given by this
Article 6 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies available to the
Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this Indenture, and no delay
or omission of the Trustee or of any holder of any of the Notes to exercise any right or power
accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair
any such right or power, or shall be construed to be a waiver of any such default or any
acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given
by this Article 6 or by law to the Trustee or to the Noteholders

36

 

may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee
or by the Noteholders.

     Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The
holders of not less than a majority in aggregate principal amount of the Notes at the time
outstanding shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee;
provided that (a) such direction shall not be in conflict with any rule of law or with this
Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction,
(c) the Trustee may decline to take any action that would benefit some Noteholder to the detriment
of other Noteholders and (d) the Trustee may decline to take any action that would involve the
Trustee in personal liability.

     The holders of 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
hereunder and its consequences except (i) a default in the payment of the principal of, or
interest (including Additional Interest, if any) on, the Notes, (ii) a failure by the Issuer to
convert any Notes as required by this Indenture, (iii) a default in the payment of the redemption
price on the Redemption Date pursuant to Article 3, (iv) a default in the payment of the repurchase
price on the Fundamental Change Repurchase Date or the Repurchase Date pursuant to Article 3 or (v)
a default in respect of a covenant or provisions hereof which under Article 9 cannot be modified or
amended without the consent of the holders of all Notes then outstanding or each Note affected
thereby.

     Upon any such waiver, the Issuer, the Trustee and the holders of the Notes shall be restored
to their former positions and rights hereunder; but no such waiver shall extend to any subsequent
or other default or Event of Default or impair any right consequent thereon. Whenever any default
or Event of Default hereunder shall have been waived as permitted by this Section 6.07, said
default or Event of Default shall for all purposes of the Notes and this 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 Event of Default or impair any right consequent thereon.

     Section 6.08. Notice of Defaults. The Trustee shall, within ninety (90) calendar days after a
Responsible Officer of the Trustee has knowledge of the occurrence of a default, mail to all
Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived
before the giving of such notice; provided that except in the case of default in the payment of the
principal of, or interest (including Additional Interest, if any) on, any of the Notes, the Trustee
shall be protected in withholding such notice if and so long as a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Noteholders.

     Section 6.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken or omitted by it as Trustee, the

37

 

filing by any party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees
and expenses, against any party litigant in such suit, having due regard to the merits and good
faith of the claims or defenses made by such party litigant; provided that the provisions of this
Section 6.09 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than ten percent in principal amount of the Notes at the time outstanding determined
in accordance with Section 8.04, or to any suit instituted by any Noteholder for the enforcement of
the payment of the principal of, or interest on, any Note on or after the due date expressed in
such Note or to any suit for the enforcement of the right to convert any Note in accordance with
the provisions of Article 13.

ARTICLE 7

The Trustee

     Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of
an Event of Default and after the curing or waiver of all Events of Default which may have
occurred, undertakes to perform such duties and only such duties as are specifically set forth in
this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of its own affairs.

     No provision of this Indenture shall be construed to relieve the Trustee from liability for
its own negligent action, its own negligent failure to act or its own willful misconduct, except
that:

     (a) prior to the occurrence of an Event of Default and after the curing or waiving of all
Events of Default which may have occurred:

     (i) the duties and obligations of the Trustee shall be determined solely by the express
provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be
liable except for the performance of such duties and obligations as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read into this
Indenture and the Trust Indenture Act against the Trustee; and

     (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the
Trustee may conclusively rely as to the truth of the statements and the correctness of the
opinions expressed therein, upon any certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but, in the case of any such certificates
or opinions which by any provisions hereof are specifically required to be furnished to the
Trustee, the Trustee shall be under a duty to examine the same to determine whether or not
they conform to the requirements of this Indenture;

     (b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining
the pertinent facts;

38

 

     (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the written direction of the holders of not less than a
majority in principal amount of the Notes at the time outstanding determined as provided in Section
8.04 relating to the time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

     (d) whether or not therein provided, every provision of this Indenture relating to the conduct
or affecting the liability of, or affording protection to, the Trustee shall be subject to the
provisions of this Section;

     (e) the Trustee shall not be liable in respect of any payment (as to the correctness of
amount, entitlement to receive or any other matters relating to payment) or notice effected by the
Issuer or any Paying Agent (other than the Trustee) or any records maintained by any co-registrar
(other than the Trustee) with respect to the Notes;

     (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to
this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its
failure to receive such notice as reason to act as if no such event occurred unless a Responsible
Officer of the Trustee has actual knowledge thereof or unless the Trustee has otherwise received
written notice thereof; and

     (g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless
a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee shall have
been notified in writing of such Event of Default by the Issuer or a holder of Notes.

     None of the provisions contained in this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur personal financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers, if there is reasonable ground for
believing that the repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     Section 7.02. Reliance on Documents, Opinions, etc. Except as otherwise provided in Section
7.01:

     (a) the Trustee may conclusively rely and shall be protected in acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent, order, bond,
debenture, note, coupon or other paper or document (whether in its original or facsimile form)
believed by it in good faith to be genuine and to have been signed or presented by the proper party
or parties;

     (b) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be
herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to
the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Issuer;

39

 

     (c) the Trustee may consult with counsel of its own selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken or
omitted by it hereunder in good faith and in reliance on and in accordance with such advice or
Opinion of Counsel;

     (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the
provisions of this Indenture, unless such Noteholders shall have offered to the Trustee reasonable
security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities
which may be incurred therein or thereby;

     (e) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture or other paper or document, but the Trustee may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Issuer, personally or by agent or attorney;

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

     (g) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by
it in good faith and reasonably believed by it to be authorized or within the discretion or rights
or powers conferred upon it by this Indenture;

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

     (i) the Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions
pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to
sign an Officers’ Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded; and

     (j) any permissive right or authority granted to the Trustee shall not be construed as a
mandatory duty.

     Section 7.03. No Responsibility for Recitals, etc. The recitals contained herein and in the
Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of
the Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The
Trustee shall not be accountable for the use or application by the Issuer of any Notes or the
proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions
of this Indenture.

40

 

     Section 7.04. Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note
Registrar May Own Notes. The Trustee, any Paying Agent, the Conversion Agent, the Bid Solicitation
Agent, or Note Registrar, in its individual or any other capacity, may become the owner or pledgee
of Notes with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent,
Bid Solicitation Agent or Note Registrar.

     Section 7.05. Monies to be Held in Trust. Subject to the provisions of Section 11.02, all
monies received by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received. Money held by the Trustee in trust hereunder need
not be segregated from other funds except to the extent required by law. Except as otherwise
provided herein, the Trustee shall be under no liability for interest on any money received by it
hereunder except as may be agreed in writing from time to time by the Issuer and the Trustee.

     Section 7.06. Compensation and Expenses of Trustee. The Issuer covenants and agrees to pay to
the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all
services rendered by it hereunder in any capacity (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time
to time in writing between the Issuer and the Trustee, and the Issuer will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances reasonably
incurred or made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the reasonable expenses and disbursements of its counsel
and of all Persons not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence, willful misconduct, recklessness or bad faith. The Issuer also
covenants to indemnify the Trustee and any predecessor Trustee (or any officer, director or
employee of the Trustee), in any capacity under this Indenture and any authenticating agent for,
and to hold them harmless against, any and all loss, liability, damage, claim or reasonable expense
including taxes (other than taxes based on the income of the Trustee) incurred without negligence,
willful misconduct, recklessness or bad faith on the part of the Trustee or such officers,
directors, employees or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this trust or in any other capacity hereunder,
including the reasonable costs and expenses of defending themselves against any claim (whether
asserted by the Issuer, any holder or any other Person) of liability in the premises. The
obligations of the Issuer under this Section 7.06 to compensate or indemnify the Trustee and to pay
or reimburse the Trustee for reasonable expenses, disbursements and advances shall be secured by a
lien prior to that of the Notes upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the holders of particular Notes. The
obligation of the Issuer under this Section shall survive the satisfaction and discharge of this
Indenture.

     When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(h), 6.01(i) or 6.01(j) with respect to the
Issuer occurs, the expenses and the compensation for the services are intended to constitute
reasonable expenses of administration under any bankruptcy, insolvency or similar laws.

     Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section
7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any

41

 

action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of gross negligence, bad faith, recklessness or willful misconduct
on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’
Certificate delivered to the Trustee.

     Section 7.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.

     Section 7.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50.0 million (or if such Person is a member of a bank
holding company system, its bank holding company shall have a combined capital and surplus of at
least $50.0 million). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.10. Resignation or Removal of Trustee.

     (a) Subject to Section 7.10(c), the Trustee may at any time resign by giving written notice of
such resignation to the Issuer and to the holders of Notes. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment sixty (60) calendar days after the
mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten
Business Days’ notice to the Issuer and the Noteholders, petition, at the expense of the Issuer,
any court of competent jurisdiction for the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

     (b) In case at any time any of the following shall occur:

     (i) the Trustee shall fail to comply with Section 7.08 after written request therefor
by the Issuer or by any Noteholder who has been a bona fide holder of a Note or Notes for at
least six months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.09 and shall fail to resign after written request therefor by the Issuer or by any
such Noteholder; or

     (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed, or

42

 

any public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Issuer may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 6.09, any Noteholder who has been a bona fide holder of a Note
or Notes for at least six months may, on behalf of itself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of
a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper
and prescribe, remove the Trustee and appoint a successor trustee.

     (c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 7.11.

     (d) Notwithstanding the replacement of the Trustee pursuant to this Section, the Issuer’s
obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

     Section 7.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 7.10 shall execute, acknowledge and deliver to the Issuer and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Issuer or of the successor trustee, the trustee ceasing
to act shall, upon payment of any amount then due it pursuant to the provisions of Section 7.06,
execute and deliver an instrument transferring to such successor trustee all the rights and powers
of the trustee so ceasing to act. Upon request of any such successor trustee, the Issuer shall
execute any and all instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 7.06.

     No successor trustee shall accept appointment as provided in this Section 7.11 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
7.08 and be eligible under the provisions of Section 7.09.

     Upon acceptance of appointment by a successor trustee as provided in this Section 7.11, the
Issuer (or the former trustee, at the written direction of the Issuer) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the holders of Notes at their
addresses as they shall appear on the Note Register. If the Issuer fails to mail such notice
within ten (10) calendar days after acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the Issuer.

43

 

     Section 7.12. Succession by Merger. Any corporation into which the Trustee may be merged or
exchanged or with which it may be consolidated, or any corporation resulting from any merger,
exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to
all or substantially all of the corporate trust business of the Trustee (including any trust
created by this Indenture), shall be the successor to the Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties hereto, provided that
in the case of any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, such corporation shall be qualified under the provisions of Section 7.08
and eligible under the provisions of Section 7.09.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or any authenticating agent appointed by such successor trustee may
authenticate such Notes in the name of the successor trustee; and in all such cases such
certificates shall have the full force that is provided in the Notes or in this Indenture; provided
that the right to adopt the certificate of authentication of any predecessor Trustee or
authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, exchange or consolidation.

     Section 7.13. Preferential Collection of Claims. If and when the Trustee shall be or become a
creditor of the Issuer (or any other obligor upon the Notes), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of the claims against the Issuer (or
any such other obligor).

ARTICLE 8

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

44

 

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 Note shall be registered upon
the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such
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, 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 entitled to accept such Officers’
Certificate as conclusive evidence of the 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, of the taking of any action by
the holders of the percentage in aggregate 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.

ARTICLE 9

Supplemental Indentures

     Section 9.01. Supplemental Indentures Without Consent of Noteholders. The Issuer, when

     (a) to evidence a successor to the Issuer and the assumption by that successor of the
obligations of the Issuer under this Indenture and the Notes;

     (b) to provide for conversion right of holders of the Notes if any reclassification or change
of shares of Common Stock or any consolidation, merger or sale of all or substantially all of the
property or assets of the Issuer;

     (c) to add to the covenants of the Issuer for the benefit of the holders of the Notes or to

     (h) to cure any ambiguity, omission, defect or inconsistency in this Indenture or make any
other provision with respect to matters or questions arising under this Indenture which the Issuer

Board of Directors, adversely affect the interests of the holders of the Notes in any material
respect;

     (i) to add or modify any provision with respect to matters or questions arising under this
Indenture which the Issuer and the Trustee may deem necessary or desirable and which will not
adversely affect the interests of the holders of the Notes in any material respect; or

     (j) to modify any provision of this Indenture to conform that provision to the description
thereof set forth in the Offering Memorandum.

     Upon the written request of the Issuer, accompanied by a copy of the resolutions of the Board
of Directors certified by the Issuer’s Secretary or Assistant Secretary authorizing the execution
of any supplemental indenture, the Trustee is hereby authorized to join with the Issuer in the
execution of any such supplemental indenture, to make any further appropriate agreements and
stipulations that may be therein contained and to accept the conveyance, transfer and

46

 

assignment of any property thereunder, but the Trustee shall not be obligated to, but may in
its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed
by the Issuer and the Trustee without the consent of the holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

     Section 9.02. Supplemental Indenture With Consent of Noteholders. With the consent (evidenced
as provided in Article 8) of the holders of not less than a majority in aggregate principal amount
of the Notes at the time outstanding, the Issuer, when authorized by the resolutions of the Board
of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or any supplemental indenture or
modifying in any manner the rights of the holders of the Notes; provided that no such supplemental
indenture shall, without the consent of the holder of each Note so affected:

     (a) impair or adversely affect the manner of calculation or rate of accrual of interest on the
Notes or change the time of payment thereof;

     (b) make the Note payable in money or securities other than that stated in the note;

     (c) change the Maturity Date;

     (d) reduce the principal amount of, or the redemption price or repurchase price specified in
Article 3 hereof with respect to, the Notes;

     (e) make any change that impairs or adversely affects the conversion rights of the holders of
the Notes;

     (f) make any change that impairs or adversely affects the right to require the Issuer to
repurchase the Notes;

     (g) impair the right to institute suit for the enforcement of any payment with respect to the

modify or amend this Indenture or to waive compliance by the Issuer with the provisions of the
Indenture; or

47

 

     (l) modify Section 6.07 or this Section 9.02.

     Upon the written request of the Issuer, accompanied by a copy of the resolutions of the Board
of Directors certified by the Issuer’s Secretary or Assistant Secretary authorizing the execution
of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent
of Noteholders as aforesaid, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such supplemental indenture.

     It shall not be necessary for the consent of the Noteholders under this Section 9.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

     Section 9.03. Effect of Supplemental Indenture. Any supplemental indenture executed pursuant
to the provisions of this Article 9 shall comply with the Trust Indenture Act, as then in effect,
provided that this Section 9.03 shall not require such supplemental indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time, if ever, such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been qualified under the
Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such
supplemental indenture that any such qualification is required prior to the time, if ever, such
qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has
been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article 9, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitation of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Issuer and the holders of Notes
shall thereafter be determined, exercised and enforced hereunder, subject in all respects to such
modifications and amendments and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

     Section 9.04. Notation on Notes. Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article 9 may bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Issuer or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of
the Trustee and the Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may, at the Issuer’s expense, be prepared and executed by the Issuer,
authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to
Section 15.11) and delivered in exchange for the Notes then outstanding, upon surrender of such
Notes then outstanding.

     Section 9.05. Evidence of Compliance of Supplemental Indenture to be Furnished to Trustee.
Prior to entering into any supplemental indenture pursuant to this Article 9, the Trustee shall be
provided with an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements of this Article 9
and is otherwise authorized or permitted by this Indenture.

ARTICLE 10

Consolidation, Merger, Sale, Conveyance and Lease

     Section 10.01. Issuer May Consolidate on Certain Terms. Subject to the provisions of Section
10.02, the Issuer shall not, in a single transaction or a series of related transactions,
consolidate with, or sell, lease or convey all or substantially all of its property and assets to,
or merge with or into, any other Person (whether or not affiliated with the Issuer), unless: (i)
the Issuer is the continuing entity, or the successor (if other than the Issuer) formed by or
resulting from any consolidation or merger or which shall have received the transfer of assets
shall be an entity organized and existing under the laws of the United States of America, any state
thereof or the District of Columbia and shall expressly assume (x) the due and punctual payment of
the principal of, and interest on, all of the Notes, and the due and punctual performance and
observance of all of the covenants and conditions in the Notes and this Indenture to be performed
or satisfied by the Issuer (including, without limitations, the obligation to convert Notes in
accordance with the provisions of Article 13 hereof) by a supplemental indenture reasonably
satisfactory in form to the Trustee and (y) all of the obligations of the Issuer under the
Registration Rights Agreement by a supplemental agreement, in each case, executed and delivered to
the Trustee by such successor; (ii) if as a result of any such consolidation, sale, lease,
conveyance or merger, the Notes become convertible into common stock or other securities issued by
a Person that is other than the Issuer or such successor Person, such Person shall fully and
unconditionally guarantee all obligations under the Notes and this Indenture; (iii) immediately
after giving effect to the transaction described above, no Event of Default or event which, after
notice or lapse of time, or both, would become an Event of Default, has occurred and is continuing;
and (iv) the Issuer has delivered to the Trustee the Officers’ Certificate and Opinion of Counsel,
if any, requested pursuant to Section 15.03.

     Section 10.02. Issuer Successor to be Substituted. In case of any such consolidation, sale,
lease, conveyance or merger in which the Issuer is not the continuing entity and upon the
assumption by the successor Person, by supplemental indenture, executed and delivered to the
Trustee and reasonably satisfactory in form to the Trustee, of the due and punctual payment of the
principal of, and interest on, all of the Notes, and the due and punctual performance and
observance of all of the covenants and conditions of this Indenture to be performed or satisfied by
the Issuer, and by supplemental agreement, executed and delivered to the Trustee and reasonably
satisfactory in form to the Trustee, of all of the obligations of the Issuer under the Registration
Rights Agreement, such successor Person shall succeed to and be substituted for the Issuer, with
the same effect as if it had been named herein as the party of this first part, and the Issuer
shall be discharged from its obligations under the Notes, this Indenture and the Registration
Rights Agreement. Such successor Person thereupon may cause to be signed, and may issue either in
its own name or in the name of the Issuer any or all of the Notes, issuable hereunder that
theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the
order of such successor Person instead of the Issuer and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Notes that previously shall have been signed and
delivered by the officers of the Issuer to the Trustee for authentication, and any Notes that such
successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose.
All the Notes so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this

49

 

Indenture as though all of such Notes had been issued at the date of the execution hereof. In
the event of any such consolidation, merger, sale, conveyance, transfer or lease, upon compliance
with this Article 10 the Person named as the “Issuer” in the first paragraph of this Indenture or
any successor that shall thereafter have become such in the manner prescribed in this Article 10
may be dissolved, wound up and liquidated at any time thereafter and such Person shall be
discharged from its liabilities as obligor and maker of the Notes and from its obligations under
this Indenture and under the Registration Rights Agreement.

     In case of any such consolidation, sale, lease, conveyance or merger, such changes in
phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may
be appropriate.

ARTICLE 11

Satisfaction and Discharge of Indenture

     Section 11.01. Discharge of Indenture. This Indenture shall cease to be of further effect
(except as to any surviving rights of conversion, registration of transfer or exchange of Notes
herein expressly provided for and except as further provided below), and the Trustee, on demand of
and at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when (a) either: (1) all Notes theretofore authenticated and delivered
(other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 11.04 and (ii) Notes for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Issuer as provided in Section 11.04) have been
delivered to the Trustee for cancellation; or (2) all such Notes not theretofore delivered to the
Trustee for cancellation have become due and payable, whether upon the Maturity Date, a Redemption
Date, a Repurchase Date or a Fundamental Change Repurchase Date or otherwise, or have all been
converted in accordance with the provisions of Article 13 hereof, and the Issuer has irrevocably
deposited or caused to be irrevocably deposited with the Trustee a Paying Agent or the Conversion
Agent (other than the Issuer or any of its Affiliates), as applicable, as trust funds in trust cash
and, if applicable, shares of Common Stock in an amount sufficient to pay and discharge the entire
indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal
and interest to the date of such deposit (in the case of Notes which have become due and payable)
or for amounts owing upon conversion; provided, however, that there shall not exist, on the date of
such deposit, a default or Event of Default; provided, further, that such deposit shall not result
in a breach or violation of, or constitute a default under, this Indenture or any other agreement
or instrument to which the Issuer is a party or to which the Issuer is bound; (b) the Issuer has
paid or caused to be paid all other sums payable hereunder by the Issuer; and (c) the Issuer has
delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein provided for relating to the satisfaction and discharge of this
Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Issuer to the Trustee under Section 7.06 shall survive and, if money shall have been deposited with
the Trustee pursuant to subclause (2) of clause (a) of this Section, the provisions of Sections
2.05, 2.06, 2.07, 3.05, 3.06, 5.01, Article 13 and this Article 11, shall survive until the Notes
have been paid in full.

50

 

     Section 11.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 11.04, all
monies deposited with the Trustee pursuant to Section 7.05, shall be held in trust for the sole
benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either
directly or through any Paying Agent (including the Issuer if acting as its own Paying Agent), to
the holders of the particular Notes for the payment or redemption of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if
any, and interest. All moneys deposited with the Trustee pursuant to Section 7.05 (and held by it
or any Paying Agent) for the payment of Notes subsequently converted shall be returned to the
Issuer upon request. The Trustee is not responsible to anyone for interest on any deposited funds
except as agreed in writing.

     Section 11.03. Paying Agent to Repay Monies Held. Subject to the provisions of Section 11.04,
the Trustee or a Paying Agent shall hold in trust, for the benefit of the Noteholders, all money
deposited with it pursuant to Section 11.01 and shall apply the deposited money in accordance with
this Indenture and the Notes to the payment of the principal of and interest on the Notes.

     Section 11.04. Return of Unclaimed Monies. The Trustee and each Paying Agent shall pay to the
Issuer upon request any money held by them for the payment of principal or interest that remains
unclaimed for two years after a right to such money has matured; provided, however, that the
Trustee or such Paying Agent, before being required to make any such payment, may, at the expense
of the Issuer, either publish in a newspaper of general circulation in The City of New York, or
cause to be mailed to each Holder entitled to such money, notice that such money remains unclaimed
and that after a date specified therein, which shall be at least thirty (30) calendar days from the
date of such mailing or publication, any unclaimed balance of such money then remaining will be
repaid to the Issuer. After payment to the Issuer, Holders entitled to money must look to the
Issuer for payment as general creditors unless an applicable abandoned property law designates
another person, and the Trustee and each Paying Agent shall be relieved of all liability with
respect to such money.

     Section 11.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money
in accordance with Section 11.02 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 11.01 until such time as the Trustee or the Paying Agent is
permitted to apply all such money in accordance with Section 11.02; provided that if the Issuer
makes any payment of principal of or premium, if any, or interest on any Note following the
reinstatement of its obligations, the Issuer shall be subrogated to the rights of the holders of
such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 12

Immunity of Incorporators, Stockholders, Officers and Directors

     Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment
of the principal of, or interest on, any Note, or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer
in this Indenture or in any supplemental indenture or in any Note, or because of the

51

 

creation of any indebtedness represented thereby, 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 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 a consideration for, the execution
of this Indenture and the issue of the Notes.

ARTICLE 13

Conversion of Notes

     Section 13.01. Right to Convert.

     (a) Subject to the restrictions on ownership of shares of Common Stock as set forth in Section
13.15 and upon compliance with the provisions of this Indenture, the holder of any Notes may
convert its Notes, or any portion thereof which is a multiple of $1,000, into cash or, as provided
herein, cash and Common Stock, with an aggregate value equal to the Conversion Value, by surrender
of such Notes so to be converted in whole or in part, together with any required funds, under the
circumstances and in the manner described in this Article 13. Holders may surrender any Notes for
conversion not previously redeemed or repurchased (1) prior to the close of business on the second
Business Day immediately preceding the Maturity Date at any time on or after December 15, 2030 and
(2) prior to December 15, 2030, only upon occurrence of one of the events set forth in clauses (i)
through (v) below.

     (i) Conversion Upon Satisfaction of Market Price Condition. A holder may surrender any
of its Notes for conversion during any calendar quarter beginning after March 31, 2006 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 130% 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.

     The Conversion Agent shall, on behalf of the Issuer, determine on a daily basis during
the time period specified in this Section 13.01(a)(i) whether the Notes shall be convertible
as a result of the occurrence of an event specified in this clause (i) and, if the Notes
shall be so convertible, the Conversion Agent shall promptly deliver to the Issuer and the
Trustee (if the Trustee is not the Conversion Agent) written notice thereof.

     (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 twenty (20) consecutive Trading Day period (the “measurement period”) in which the
Trading Price per $1,000 principal amount of Notes (as determined

52

 

following a reasonable request by a holder of the Notes) on each Trading Day of such
measurement period was less than 95% of the product of the Closing Sale Price of the Common
Stock multiplied by the Conversion Rate in effect on the applicable Trading Day.

     ”Trading Price” means, with respect to a Note on any date of determination, the average
of the secondary market bid quotations per $1,000 principal amount of Notes obtained by the
Bid Solicitation Agent for $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 the Initial
Purchasers; provided that if at least two such bids cannot reasonably be obtained by the Bid
Solicitation Agent, but one such bid can reasonably be obtained by the Bid Solicitation
Agent, then one bid shall be used; provided, further, that if the Bid Solicitation Agent
cannot reasonably obtain at least one bid for $5.0 million 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 will be deemed to be less than 95% of the
product of the Closing Sale Price and the Conversion Rate on such determination date.

     The Bid Solicitation Agent 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 reasonable
evidence that the Trading Price per $1,000 principal amount of Notes would be less than 95%
of the product of the Closing Sale Price and the applicable Conversion Rate, whereupon the
Issuer shall instruct the Bid Solicitation Agent 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 95% of the product of the Closing Sale Price 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 5:00 p.m., New York City time, on
the second Trading Day immediately preceding the Redemption Date. The right to convert
Notes pursuant to this clause (iii) shall expire after 5:00 p.m., New York City time, on the
second Trading Day immediately preceding the Redemption Date unless the Issuer defaults in
making the payment due upon redemption.

     (iv) Conversion Upon Specified Corporate Transactions. If the Issuer elects to: (1)
distribute to all holders of Common Stock rights entitling them to purchase, for a period
expiring within sixty (60) calendar 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 per share of Common Stock on the Trading Day immediately preceding the
declaration date of such distribution; or (2) distribute to all holders of Common Stock
assets, debt securities or rights to purchase securities of the Issuer, which distribution
has a per share value exceeding 10% of the Closing Sale Price per share of Common Stock on
the Trading Day immediately preceding the declaration date of such distribution, the Issuer
must notify holders of Notes at least twenty (20) calendar days

53

 

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 and 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 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.

     In addition, if the Issuer is a party to a consolidation, merger, binding share
exchange or sale or conveyance of all or substantially all of its properties and assets, in
each case pursuant to which all of the shares of Common Stock would be exchanged for cash,
securities and/or other property that does not also constitute a Fundamental Change, a
holder may surrender its Notes for conversion at any time from and including the date that
is fifteen (15) Business Days prior to the anticipated effective time of the transaction up
to and including five (5) Business Days after the actual date of such transaction. In such
case, then, at the effective time of the transaction, the right to convert a Note into cash
and, if applicable, shares of Common Stock will be changed in the manner provided in Section
13.06. The Issuer shall notify holders of Notes as promptly as practicable following the
date such transaction is publicly announced (but in no event less than fifteen (15) Business
Days prior to the effective time of such transaction).

     (v) Conversion Upon a Fundamental Change. If a Fundamental Change occurs, a holder of
Notes may convert its Notes at any time beginning fifteen (15) Business Days prior to the
date announced by the Issuer as the anticipated Effective Date of the Fundamental Change up
to and including the fifth Business Day following the Effective Date of the Fundamental
Change. The Issuer shall notify holders of the Notes of the anticipated Effective Date of
the Fundamental Change as promptly as practicable following the date on which it publicly
announces a Fundamental Change (but in no event less than twenty (20) Business Days prior to
the anticipated Effective Date of the Fundamental Change).

     (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 or 3.06 may
be converted only if such Repurchase Notice is withdrawn in accordance with Section 3.07 prior to
the close of business on the Repurchase Date or the Fundamental Change Repurchase Date, as
applicable.

     (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.

     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 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 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

55

 

principal amount being converted; provided that no such payment need be made (1) if a holder
converts its Notes in connection with a redemption and the Issuer has specified a Redemption Date
that is after a Record Date and on or prior to the corresponding Interest Payment Date, (2) if a
holder converts its Notes in connection with a Fundamental Change and the Issuer has specified a
Fundamental Change Repurchase Date that is after a Record Date and on or prior to the corresponding
Interest Payment Date or (3) 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. Except as otherwise provided above in this Article 13, no payment or other
adjustment shall be made for interest 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 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. If any fractional share of stock would be issuable upon the conversion of
any Note or Notes, the Issuer shall make an adjustment and payment therefor in cash to the holder
of Notes at a price equal to the Twenty Day Weighted Average Price applicable to such conversion.

     Section 13.04. Conversion Rate. The Conversion Rate for the Notes is 35.2988 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 from time
to time by the Issuer as follows:

     (a) In case the Issuer shall hereafter pay a dividend or make a distribution to all or
substantially all holders of the outstanding Common Stock in shares of Common Stock, the Conversion
Rate shall be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect at the opening of business on the date following the

56

 

date fixed for the determination of stockholders entitled to receive such dividend or other
distribution by a fraction,

     (i) the numerator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution plus the total number of shares of
Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following
the date fixed for such determination. For the purpose of this paragraph (a), the number of shares
of Common Stock at any time outstanding shall not include shares held in the treasury of the
Issuer. The Issuer will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Issuer. If any dividend or distribution of the type described in this
Section 13.05(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted
to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared.

     (b) In case outstanding shares of Common Stock shall be subdivided or split into a greater
number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the
day following the day upon which such subdivision becomes effective shall be proportionately
increased, and conversely, in case outstanding shares of Common Stock shall be combined into a
smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective immediately after the
opening of business on the day following the day upon which such subdivision or combination becomes
effective.

     (c) In case the Issuer shall issue rights or warrants to all or substantially all holders of
its outstanding shares of Common Stock entitling them (for a period expiring within sixty (60)
calendar days after the date fixed for determination of stockholders entitled to receive such
rights or warrants) to subscribe for or purchase shares of Common Stock or securities convertible
into or exchangeable or exercisable for Common Stock at a price per share (or having an exercise,
conversion or exchange price) less than the Closing Sale Price of the Common Stock on the Business
Day immediately preceding the date of announcement of such issuance of such rights or warrants, the
Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying
the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders
entitled to receive such rights or warrants by a fraction,

     (i) the numerator of which shall be the number of shares of Common Stock outstanding on
the date fixed for determination of stockholders entitled to receive such rights or warrants
plus the total number of additional shares of Common Stock offered (or underlying such
convertible, exchangeable or exercisable securities offered) for subscription or purchase,
and

57

 

     (ii) the denominator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the date fixed for determination of stockholders
entitled to receive such rights or warrants plus the number of shares of Common Stock (or
convertible, exchangeable or exercisable securities) that the aggregate offering price of
the total number of shares (or convertible, exchangeable or exercisable securities) so
offered for subscription or purchase (or the aggregate conversion, exchange or exercise
price) would purchase at the Current Market Price on such date.

     Such adjustment shall be successively made whenever any such rights or warrants are issued,
and shall become effective immediately after the opening of business on the day following the date
fixed for determination of stockholders entitled to receive such rights or warrants. To the extent
that shares of Common Stock are not delivered after the expiration of such rights or warrants, the
Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of
only the number of shares of Common Stock actually delivered. If such rights or warrants are not
so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be
in effect if such date fixed for the determination of stockholders entitled to receive such rights
or warrants had not been fixed. In determining whether any rights or warrants entitle the holders
to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in
determining the aggregate offering price of such shares of Common Stock, there shall be taken into
account any consideration received by the Issuer for such rights or warrants and any amount payable
on exercise or exchange thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors.

     (d) In case the Issuer shall, by dividend or otherwise, distribute to all or substantially all
holders of Common Stock shares of any class of capital stock of the Issuer or evidences of its
indebtedness or assets (including securities, but excluding (i) any dividends, distributions,
rights, warrants, options, other securities or convertible securities referred to in Sections
13.01(a) or 13.05(c), (ii) any dividends and distributions in connection with a reclassification,
change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or other
disposition to which Section 13.06 applies or (iii) dividends or distributions paid exclusively in
cash) (any of the foregoing hereinafter in this Section 13.05(d) called the “Securities”), then, in
each such case, the Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect on the record date with respect to such
distribution by a fraction,

     (i) the numerator of which shall be the Current Market Price on such record date; and

     (ii) the denominator of which shall be the Current Market Price on such record date
less the Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive, and described in a resolution of the Board of Directors) on the record
date of the portion of the Securities so distributed applicable to one share of Common
Stock,

58

 

such adjustment to become effective immediately prior to the opening of business on the day
following such record date; provided that if the then Fair Market Value (as so determined) of the
portion of the Securities so distributed applicable to one share of Common Stock is equal to or
greater than the Current Market Price on the record date, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Noteholder shall have the right to receive upon
conversion the amount of Securities such holder would have received had such Noteholder held a
number of Shares of Common Stock equal to Conversion Rate in effect on the record date. If such
dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. If the Board of Directors determines the Fair Market Value of any distribution for
purposes of this Section 13.05(d) by reference to the actual or when issued trading market for any
securities, it must in doing so consider the prices in such market over the same period used in
computing the Current Market Price on the applicable record date.

     If the dividend or distribution requiring an adjustment pursuant to this Section 13.05(d)
consists of capital stock of any class or series, or similar equity interests, of a Subsidiary or
other business unit of the Issuer, for purposes of making such adjustment, (i) the Current Market
Price shall be based on the average of the Closing Sale Prices of such securities for the ten
Trading Days commencing on and including the fifth Trading Day after the date on which “ex-dividend
trading” commences for such distribution on The New York Stock Exchange or such other national or
regional exchange or market on which such securities are then listed or quoted, and (ii) the Fair
Market Value of such securities shall be determined as provided herein, measured for the same
period.

     Rights or warrants distributed by the Issuer to all or substantially all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the Issuer’s capital
stock (either initially or under certain circumstances), which rights or warrants, until the
occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with
such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of
future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this
Section 13.05 (and no adjustment to the Conversion Rate under this Section 13.05 will be required)
until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is required) to the
Conversion Rate shall be made under this Section 13.05(d). If any such right or warrant, including
any such existing rights or warrants distributed prior to the date of this Indenture, are subject
to events, upon the occurrence of which such rights or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date of the occurrence of
any and each such event shall be deemed to be the date of distribution and record date with respect
to new rights or warrants with such rights (and a termination or expiration of the existing rights
or warrants without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event
(of the type described in the preceding sentence) with respect thereto that was counted for
purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 13.05 was made, (1) in the case of any such rights or warrants that shall all have
been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be
readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger
Event, as the case may be, as though it were a cash

59

 

distribution, equal to the per share redemption or repurchase price received by a holder or
holders of Common Stock with respect to such rights or warrants (assuming such holder had retained
such rights or warrants), made to all holders of Common Stock as of the date of such redemption or
repurchase, and (2) in the case of such rights or warrants that shall have expired or been
terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if
such rights and warrants had not been issued.

     No adjustment of the Conversion Rate shall be made pursuant to this Section 13.05(d) in
respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent
that such rights or warrants are actually distributed, or reserved by the Issuer for distribution
to holders of Notes (in an amount per Note equal to the number of such rights or warrants that
shall have been distributed in respect of a number of shares of Common Stock equal to the
Conversion Rate in effect at the times of such Trigger Event) upon conversion by such holders of
Notes in accordance with this Article 13.

     For purposes of this Section 13.05(d) and Section 13.05(a) and (c), any dividend or
distribution to which this Section 13.05(d) is applicable that also includes shares of Common
Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (to which the
provisions of Section 13.05(a) or 13.05(c) or both would apply), shall be deemed instead to be (1)
a dividend or distribution of the Securities other than such shares of Common Stock or rights or
warrants (and any Conversion Rate adjustment required by this Section 13.05(d) with respect to such
dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution
of such shares of Common Stock or such rights or warrants (and any further Conversion Rate
adjustment required by Sections 13.05(a) and 13.05(c) with respect to such dividend or distribution
shall then be made), except (A) the record date of such dividend or distribution shall be
substituted as “the date fixed for the determination of stockholders entitled to receive such
dividend or other distribution”, “the date fixed for the determination of stockholders entitled to
receive such rights or warrants” and “the date fixed for such determination” within the meaning of
Section 13.05(a) and 13.05(c), respectively, and (B) any shares of Common Stock included in such
dividend or distribution shall not be deemed “outstanding at the close of business on the date
fixed for such determination” within the meaning of Section 13.05(a).

     (e) In case the Issuer shall, by dividend or otherwise, distribute to all or substantially all
holders of its Common Stock cash (excluding (x) any dividend or distribution in connection with the
liquidation, dissolution or winding up of the Issuer, whether voluntary or involuntary, (y) any
cash dividend distributed on the Common Stock to the extent the aggregate of all cash dividends per
share of Common Stock in any Fiscal Quarter does not exceed $0.30 (the “dividend threshold amount”)
and (z) any dividend or distribution in connection with a reclassification, change, consolidation,
merger, binding share exchange, sale, transfer, lease, conveyance or other disposition to which
Section 13.06 applies), then, in such case, the Conversion Rate shall be increased so that the same
shall equal the rate determined by multiplying the Conversion Rate in effect on the applicable
record date by a fraction,

     (i) the numerator of which shall be the Current Market Price on such record date minus
the dividend threshold amount; and

60

 

     (ii) the denominator of which shall be the Current Market Price on such record date
minus the full amount of cash distributed in the applicable Fiscal Quarter in respect of one
share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on the day following
the record date. If such dividend or distribution is not so paid or made, the Conversion Rate
shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.

     The “dividend threshold amount” shall be subject to adjustment as of any date on which the
Conversion Rate of the Notes is adjusted pursuant to this Section 13.05 (other than on account of
any adjustment to the Conversion Rate as a result of the provisions set forth in this Section
13.05(e)). The dividend threshold amount, as adjusted, will equal the dividend threshold amount
immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the
Conversion Rate immediately prior to the adjustment giving rise to the dividend threshold amount
adjustment and (ii) the denominator of which is the Conversion Rate as so adjusted.

     (f) In case a tender or exchange offer made by the Issuer or any Subsidiary of the Issuer for
all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended
upon the expiration thereof) shall require the payment to stockholders of consideration per share
of Common Stock having a fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of Directors) that as
of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender
or exchange offer (as it may be amended) exceeds the Current Market Price (which, for purposes of
this Section 13.05(f), shall mean the average of the Closing Sale Prices of the Common Stock for
the ten consecutive Trading Days ending on the Trading Day immediately prior to the Expiration
Time), the Conversion Rate shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

     (i) the numerator of which shall be the sum of (x) the fair market value (determined as
aforesaid) of the aggregate consideration payable to stockholders based on the acceptance
(up to any maximum specified in the terms of the tender or exchange offer) of all shares
validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed
so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the
product of the number of shares of Common Stock outstanding (less any Purchased Shares) at
the Expiration Time and the Current Market Price immediately prior to the Expiration Time,
and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) at the Expiration Time multiplied by the
Current Market Price immediately prior to the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day
following the Expiration Time. If the Issuer is obligated to purchase shares pursuant to any such
tender or exchange offer, but the Issuer is permanently prevented by applicable law from

61

 

effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer
had not been made.

     (g) For purposes of this Section 13.05, the following terms shall have the meaning indicated:

     (i) “Current Market Price” shall mean the average of the daily Closing Sale Prices per
share of Common Stock over the ten consecutive Trading Days ending on the earlier of such
date of determination and the day before the “ex” date with respect to the issuance,
distribution, subdivision or combination requiring such computation. For purpose of this
paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution,
means the first date on which the Common Stock trades, regular way, on the relevant exchange
or in the relevant market from which the Closing Sale Price was obtained without the right
to receive such issuance or distribution, and (2) when used with respect to any subdivision
or combination of shares of Common Stock, means the first date on which the Common Stock
trades, regular way, on such exchange or in such market after the time at which such
subdivision or combination becomes effective.

     If another issuance, distribution, subdivision or combination to which Section 13.05
applies occurs during the period applicable for calculating “Current Market Price” pursuant
to the definition in the preceding paragraph, “Current Market Price” shall be calculated for
such period in a manner determined by the Board of Directors to reflect the impact of such
issuance, distribution, subdivision or combination on the Closing Sale Price of the Common
Stock during such period.

     (ii) “Fair Market Value” shall mean the amount which a willing buyer would pay a
willing seller in an arm’s-length transaction.

     (iii) “record date” shall mean, with respect to any dividend, distribution or other
transaction or event in which the holders of Common Stock have the right to receive any
cash, securities or other property or in which the Common Stock (or other applicable
security) is exchanged for or exchanged into any combination of cash, securities or other
property, the date fixed for determination of stockholders entitled to receive such cash,
securities or other property (whether such date is fixed by the Board of Directors or by
statute, contract or otherwise).

     (h) [Intentionally omitted]

     (i) The Issuer may make such increases in the Conversion Rate, in addition to those required
by Section 13.05(a) through (f) as the Board of Directors considers to be advisable to avoid or
diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting
from any dividend or distribution of stock (or rights to acquire stock) or from any event treated
as such for income tax purposes.

     To the extent permitted by applicable law, the Issuer from time to time may increase the
Conversion Rate by any amount for any period of time if the increase is irrevocable during the
period and the Board of Directors shall have made a determination that such increase would be in

62

 

the best interests of the Issuer, which determination shall be conclusive. Whenever the
Conversion Rate is increased pursuant to the preceding sentence, the Issuer shall mail to holders
of record of the Notes at least fifteen (15) calendar days prior to the date increased Conversion
Rate takes effect, a notice of the increase, and such notice shall state the increased Conversion
Rate and the period during which it will be in effect.

     (j) No adjustment in the Conversion Rate will be made: (a) upon the issuance of any shares of
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
shares of Common Stock under any plan; (b) upon the issuance of any shares of Common Stock or
options or rights to purchase such shares pursuant to any present or future employee, director, or
consultant benefit plan or program of the Issuer; (c) upon 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 hereof; (d) for a change in the par value or a change to no par value of
the Common Stock; or (e) for accrued and unpaid interest (including Additional Interest, if any).

     (k) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that any
adjustments that by reason of this Section 13.05(k) are not required to be made shall be carried
forward and the Issuer shall make such carry forward adjustments, regardless of whether the
aggregate adjustment is less than 1%, upon redemption, upon a Fundamental Change or at maturity, as
applicable. All calculations under this Article 13 shall be made by the Issuer and shall be made
to the nearest cent or to the nearest one-thousandth (1/1,000) of a share, as the case may be.
Except as otherwise provided in this Indenture, no adjustment need be made for any issuance of
Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or
convertible or exchangeable securities. Interest will not accrue on any cash into which the Notes
are convertible.

     (l) 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 holder of each Note at its last address appearing on the
Note Register provided for in Section 2.05 of this Indenture, within twenty (20) calendar days
after execution thereof. Failure to deliver such notice shall not affect the legality or validity
of any such adjustment.

     (m) [Intentionally Omitted]

     (n) 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

63

 

shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock. The Issuer will not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Issuer.

     (o) 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 or an
additional interest payment, the Issuer may set off any withholding tax it is required to collect
with respect to any such deemed distribution or payment against cash payments of interest in
accordance with Section 2.03 or from cash and shares of 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 Section 3.01, 3.05 or
3.06 hereof.

     (p) No adjustment to the Conversion Rate shall be made pursuant to this Section 13.05 if the
holders of the Notes may participate, on an as converted basis (assuming for this purpose that the
Notes were convertible solely into Common Stock at the applicable Conversion Rate), in the
transaction that would otherwise give rise to adjustment pursuant to this Section 13.05.

     Section 13.06. Change in Conversion Right Upon Certain Reclassifications, Business
Combinations and Asset Sales.

     (a) If any of the following shall occur (including as a result of a Fundamental Change),
namely: (i) any reclassification or change of outstanding shares of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination); (ii) any consolidation, merger or binding share exchange
to which the Issuer is a party other than a merger in which the Issuer is the resulting or
surviving corporation and which does not result in any reclassification of, or change (other than a
change in name, or par value, or from par value to no par value, or from no par value to par value,
or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (iii)
any sale, transfer, lease, conveyance or other disposition of all or substantially all of the
properties and assets of the Issuer, in each case, pursuant to which holders of Common Stock would
be entitled to receive stock, other securities, other property, assets or cash in exchange for
their Common Stock, then the Issuer, or such successor or purchasing corporation, as the case may
be, shall, as a condition precedent to such reclassification, change, consolidation, merger,
binding share exchange, sale, transfer, lease, conveyance or other disposition, execute and deliver
to the Trustee a supplemental indenture providing that the holder of each Note then outstanding
shall have the right to convert such Note by reference to the kind and amount of cash, securities
or other property that a holder of the number of shares of Common Stock equal to the Conversion
Rate of such Note immediately prior to such transaction would have owned or been entitled to
receive (the “Reference Property”). Such supplemental indenture shall (a) provide for adjustments
of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments
of the Conversion Rate provided for in this Article 13, including, without limitation, the
provisions of Sections 13.12 and 13.13, (b) provide that from and after the effective time of such
transaction, a Noteholder will be entitled thereafter to convert its Notes into cash (up to the
aggregate principal amount thereof) and Reference Property (or cash in lieu thereof) based on the
Twenty Day Weighted Average Price of the

64

 

Reference Property and the applicable Conversion Rate as set forth in Section 13.12 and set
forth such other appropriate modifications to the means of determining the Conversion Value and
settlement provisions specified in this Article 13 so as to be nearly equivalent to such provisions
applicable on the date hereof with respect to the Common Stock as may be practicable and (c)
specify the Conversion Rate immediately after such transaction. Notwithstanding the foregoing, a
distribution by the Issuer to all or substantially all holders of Common Stock for which an
adjustment to the Conversion Rate or provision for conversion of the Notes may be made pursuant to
Section 13.05 shall not be deemed to be a sale or conveyance of all or substantially all of the
properties and assets of the Issuer for purposes of this Section 13.06.

     (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) In the event holders of shares of Common Stock have the opportunity to elect the form of
consideration to be received in such reclassification, change, consolidation, merger, binding share
exchange, sale, transfer, lease, conveyance or other disposition, the Issuer shall make adequate
provision whereby the holders of the Notes shall have a reasonable opportunity to determine the
form of consideration into which the Notes shall be convertible from and after the effective date
of such transaction, in each case, for purposes of all outstanding Notes, treated as a single
class.

     (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.

     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.

65

 

     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.

     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

66

 

     (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 rights provided for in the Issuer’s Rights
Agreement dated as of September 14, 1999 or in any future rights plan adopted by the Issuer have
separated from the shares of Common Stock in accordance with the provisions of the applicable
stockholder rights agreement so that the holders of the Notes would not be entitled to receive any
rights in respect of Common Stock issuable upon conversion of the Notes, if any, the Conversion
Rate will be adjusted as provided in Section 13.05(d). To the extent that the rights under any
such rights plan shall not have separated from the Common Stock, holders who convert Notes shall be
entitled to receive (to the extent that Common Stock shall be issued upon such conversion) the
rights under any such rights plan.

     Section 13.12. Settlement Upon Conversion.

     (a) Upon the tender of Notes for conversion by the holder thereof in accordance with the
provisions of this Indenture, the Issuer shall satisfy its obligation upon conversion (the
“Conversion Obligation”) by payment and delivery of cash and, if applicable as provided herein,
shares of Common Stock, the aggregate value of which (the “Conversion Value”), for each $1,000
aggregate principal amount of Notes so converted, shall be equal to the product of:

     (i) the Conversion Rate in effect on the Conversion Date; and

     (ii) the average of the daily Volume Weighted Average Prices of the Common Stock for
each of the twenty (20) consecutive Trading Days (appropriately adjusted to

67

 

take into account the occurrence during such period of stock splits and similar events)
beginning on the second Trading Day immediately following the day the Notes are tendered for
conversion (the “Twenty Day Weighted Average Price”). The “Volume Weighted Average Price”
per share of the Common Stock on any Trading Day will be the volume weighted average price
on the New York Stock Exchange or, if the Common Stock is not listed on the New York Stock
Exchange, on the principal U.S. national or regional securities exchange, the Nasdaq
National Market or over-the-counter market on which the Common Stock is then listed or
traded, from 9:30 a.m. to 4:00 p.m. (New York City time) on such Trading Day as displayed by
Bloomberg (or if such volume weighted average price is not available, the market value of
one share on such Trading Day as the Board of Directors determine in good faith using a
volume weighted averaging method).

     (b) The Issuer shall deliver the Conversion Value of the Notes surrendered for conversion to
converting holders as follows:

     (i) an amount in cash (the “Principal Return”) equal to the lesser of (A) the aggregate
Conversion Value of the Notes to be converted and (B) the aggregate principal amount of the
Notes to be converted;

     (ii) if the aggregate Conversion Value of the Notes to be converted is greater than the
Principal Return, an amount in cash (the “Net Cash Amount”) or, at the election of the
Issuer, an amount in whole shares of Common Stock (the “Net Shares Amount”), determined
pursuant to Section 13.12(c), or a combination thereof equal to such aggregate Conversion
Value less the Principal Return (the “Net Amount”); and

     (iii) an amount in cash in lieu of any fractional shares of Common Stock.

     (c) The Net Cash Amount to be paid shall equal that portion of the Net Amount to be paid in
cash. The Net Shares Amount to be paid will be determined by dividing that portion of the Net
Amount to be delivered in shares of Common Stock by the Twenty Day Weighted Average Price. The
cash payment for fractional shares shall, in accordance with the provisions of Section 13.03, be
based on the Twenty Day Weighted Average Price.

     (d) The Conversion Value, Principal Return, Net Amount, Net Cash Amount and Net Shares Amount
shall be determined by the Issuer at the end of the twenty (20) consecutive Trading Day period
beginning on the second Trading Day immediately following the day the Notes are tendered for
conversion (the “Averaging Period”). Prior to the close of business on the Trading Day next
following the day on which Notes are tendered for conversion, the Issuer shall notify holders of
such Notes of the Issuer’s election to pay cash for all or a portion of the Net Amount and, if
applicable, the percentage of the Net Amount that the Issuer shall pay in cash and the percentage
of the Net Amount that the Issuer shall pay in shares of Common Stock.

     (e) Payment of the cash and Net Amount, if any, in satisfaction of the Conversion Obligation
shall be made by the Issuer as promptly as practicable following the last Trading Day of the
Averaging Period, but in no event later than three Business Days thereafter by paying in cash the
Principal Return, the Net Cash Amount and any cash in lieu of fractional shares to the holder of a
Note surrendered for conversion, or such holder’s nominee or nominees, and issue, or

68

 

cause to be issued, and deliver to the Conversion Agent or to such holder, or such holder’s
nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of
full shares of Common Stock equal to the Net Shares Amount, if any, to which such holder shall be
entitled as part of such Conversion Obligation.

     Section 13.13. Conversion Rate Adjustment After Certain Fundamental Changes.

     (a) Subject to the provisions hereof, if a Noteholder elects to convert its Notes pursuant to
Section 13.01(a)(v) following the occurrence of a transaction described in clause (1) or (2) of the
definition of Fundamental Change that occurs prior to January 15, 2011, the Issuer shall increase
the applicable Conversion Rate for the Notes so surrendered for conversion by the number of
additional shares of Common Stock (the “Additional Shares”) specified below. A conversion of Notes
will be deemed for these purposes to be “in connection with” such a Fundamental Change, subject to
Section 13.14, if the Conversion Notice is received by the Conversion Agent from and including the
date that is fifteen (15) Business Days prior to the anticipated Effective Date of the Fundamental
Change until and including the fifth Business Day following the Effective Date. The Issuer shall
notify holders of the Notes at least twenty (20) Business Days prior to the anticipated Effective
Date of the Fundamental Change transaction of such anticipated Effective Date and whether the
Issuer elects, if such transaction is also a Public Acquirer Change of Control, to modify the
Conversion Obligation in the manner set forth in Section 13.14 in lieu of increasing the Conversion
Rate.

     (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 Fundamental Change becomes effective (the “Effective
Date”) and the price paid per share of the Common Stock in the Fundamental Change transaction (the
“Stock Price”). If holders of the Common Stock receive only cash in the Fundamental Change
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 over the ten consecutive Trading Days up to but excluding the Effective
Date.

     (c) The Stock Prices set forth in the first column of the table set forth in Section 13.13(e)
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.

69

 

     (e) The following table sets forth the Stock Price and number of Additional Shares issuable
per $1,000 principal amount of Notes:

     (f) If the exact Stock Price and Effective Date are not set forth on the table above,
then:

     (i) If the Stock Price is between two Stock Price amounts in the table or the Effective
Date is between two Effective Dates in the table, the number of Additional Shares shall be
determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Price amounts and the two dates, as applicable, based
on a 365-day year.

     (ii) If the Stock Price is in excess of $40.00 per share, subject to adjustment, the
Issuer shall not increase the Conversion Rate by any Additional Shares.

     (iii) If the Stock Price is less than $23.51 per share, subject to adjustment, the
Issuer shall not increase the Conversion Rate by any Additional Shares.

     (g) Notwithstanding the provisions of this Section 13.13, in no event shall the total number
of shares of Common Stock issuable upon conversion of the Notes exceed 42.5351 shares per $1,000
principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate as set
forth in Section 13.05.

     Section 13.14. Conversion Right After Public Acquirer Change of Control.

     (a) Notwithstanding the foregoing, if a transaction described in clause (1) or (2) of the
definition of Fundamental Change occurs prior to January 15, 2011, in lieu of adjusting the
Conversion Rate as set forth in Section 13.13, the Issuer shall be permitted, in the case of a
Public Acquirer Change of Control, at any time prior to the twentieth Business Day immediately
preceding the proposed Effective Date of the Public Acquirer Change of Control, irrevocably elect
to change the Conversion Obligation with respect to the Notes into an obligation to deliver, upon
conversion of the Notes, cash and shares of Public Acquirer Common Stock, if any, equal to the
Conversion Value in the same manner as the Issuer would otherwise be required to satisfy the
Conversion Obligation pursuant to Section 13.12 in respect of the shares of Common Stock. If the
Issuer makes such an election, the Conversion Rate applicable to any Notes converted after

70

 

such election shall be a number of shares of Public Acquirer Common Stock equal to the
Conversion Rate in effect immediately before the Effective Date of the Public Acquirer Change of
Control multiplied by a fraction:

     (i) the numerator of which will be (1) in the case of a share exchange, consolidation,
merger, or binding share exchange pursuant to which the Common Stock is converted into cash,
securities, or other property, the value of all cash, securities, and other property (as
determined by the Board of Directors) paid or payable per share of Common Stock or (2) in
the case of any other Public Acquirer Change of Control, the average of the Closing Sale
Prices of the Common Stock for the five consecutive Trading Days prior to but excluding the
Effective Date of such Public Acquirer Change of Control; and

     (ii) the denominator of which shall be the average of the Closing Sale Prices of the
Public Acquirer Common Stock for the five consecutive Trading Days prior to but excluding
the Effective Date of such Public Acquirer Change of Control.

     (b) If the Issuer elects to adjust the Conversion Rate and Conversion Obligation in connection
with a Public Acquirer Change of Control pursuant to Section 13.14(a), the Issuer shall be required
to send holders of Notes written notice not later than twenty (20) Business Days prior to but
excluding the expected Effective Date of the Public Acquirer Change of Control. If the Issuer
makes such an election, holders who tender their Notes for conversion shall not have the right to
any increase in the Conversion Rate pursuant to Section 13.13.

     Section 13.15. Ownership Limit; Withholding Tax.

     (a) Notwithstanding any other provision of the Notes, no holder of Notes shall be entitled to
receive shares of Common Stock upon a conversion of Notes to the extent that receipt of such shares
would cause such holder (together with such holder’s Affiliates) to exceed the ownership limit
contained in the Charter of the Issuer. In such case, the Issuer shall satisfy its obligation in
respect of the Net Amount owing upon conversion solely in cash such that such holder shall be
entitled to receive solely cash in respect of to the Conversion Value owing upon conversion of such
holder’s Notes.

     (b) At the Maturity Date or upon earlier redemption or repurchase of the Notes or otherwise,
and as otherwise required by law, the Issuer may deduct and withhold from the amount of
consideration otherwise deliverable to the Holder the amount required to be deducted and withheld
under applicable law.

     Section 13.16. Calculation In Respect of Notes. Except as otherwise specifically stated
herein or in the Notes, all calculations to be made in respect of the Notes shall be the obligation
of the Issuer. All calculations made by the Issuer or its agent as contemplated pursuant to the
terms hereof and of the Notes shall be made in good faith and be final and binding on the Notes and
the holders of the Notes absent manifest error. The Issuer shall provide a schedule of calculations
to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by
the Issuer without independent verification. The Trustee shall forward calculations made by the
Issuer to any Holder of Notes upon request.

reference only, are not to be considered a part hereof, and shall in no way modify or restrict any

     Section 15.11. Authenticating Agent. The Trustee may appoint an authenticating agent that
shall be authorized to act on its behalf, and subject to its direction, in the authentication and
delivery of Notes in connection with the original issuance thereof and transfers and exchanges of
Notes hereunder, including under Sections 2.04, 2.05, 2.06, 2.07, 3.03, 3.05 and 3.06, as fully to
all intents and purposes as though the authenticating agent had been expressly authorized by this
Indenture and those Sections to authenticate and deliver Notes. For all purposes of this
Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to
be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such
authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant
to Section 7.09.

     Any corporation into which any authenticating agent may be merged or exchanged or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or exchange to
which any authenticating agent shall be a party, or any corporation succeeding to the corporate
trust business of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this Section 15.11, without
the execution or filing of any paper or any further act on the part of the parties hereto or the
authenticating agent or such successor corporation.

     Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Issuer. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Issuer. Upon
receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee shall either
promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor
authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Issuer and shall mail notice of such appointment of a successor
authenticating agent to all holders of Notes as the names and addresses of such holders appear on
the Note Register.

     The Issuer agrees to pay to the authenticating agent from time to time such reasonable
compensation for its services as shall be agreed upon in writing between the Issuer and the
authenticating agent.

     The provisions of Sections 7.02, 7.03, 7.04 and 8.03 and this Section 15.11 shall be
applicable to any authenticating agent.

74

 

     Section 15.12. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute
but one and the same instrument.

     Section 15.13. Severability. In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

     SunTrust Bank hereby accepts the trusts in this Indenture declared and provided, upon the
terms and conditions herein above set forth.

FORM OF REVERSE OF NOTE

UNITED DOMINION REALTY TRUST, INC.

4.00% CONVERTIBLE SENIOR NOTES DUE 2035

     This note is one of a duly authorized issue of notes of the Issuer, designated as its “4.00%
Convertible Senior Notes due 2035” (herein called the “Notes”), issued under and pursuant to an
Indenture, dated as of December 19, 2005 (herein called the “Indenture”), between the Issuer and
SunTrust Bank, 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 not have the right to redeem the Notes prior to January 15, 2011, except 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, but
excluding, the Redemption Date. At any time on or after January 15, 2011, the Notes may be
redeemed at the option of the Issuer, in whole or in part, in cash at a redemption price equal to
100% of the principal amount of Notes to be redeemed plus accrued and unpaid interest accrued
thereon to, but excluding, the Redemption Date. If an Interest Payment Date falls on or prior to
the Redemption Date, then the interest payable on such Interest Payment Date shall be paid to the
holders of record of the Notes on the applicable Record Date instead of the holders surrendering
the Notes for redemption.

     Subject to the terms and conditions set forth in the Indenture, following the occurrence of
Fundamental Change at any time prior to the Maturity Date, the Notes shall be subject to repurchase
by the Issuer, at the option of the holder, on the Fundamental Change Repurchase Date, at a
repurchase price equal to 100% of the principal amount of the Notes to be repurchased together with
accrued and unpaid interest accrued thereon to, but excluding, the Fundamental Change Repurchase
Date; provided that if an Interest Payment Date falls on or prior to the Fundamental Change
Repurchase Date, then, with respect to any Note in respect of which the holder thereof shall have
submitted a Repurchase Notice, the interest payable on such Interest Payment Date shall be paid to
the holder of record of such Note on the applicable Record Date instead of the holder surrendering
such Note for repurchase. 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 Fundamental
Change Repurchase Date.

     Subject to the terms and conditions of the Indenture, each holder shall have the right, at
such holder’s option, to require the Issuer to repurchase all or any portion of the Notes held by
such holder, on January 15, 2011, December 15, 2015, December 15, 2020, December 15, 2025 and
December 15, 2030, at a repurchase price equal to 100% of the principal amount of the Notes to be
repurchased together with any accrued and unpaid interest accrued thereon to, but excluding, the
Repurchase Date; provided that if an Interest Payment Date falls on or prior to a

A-6

 

Repurchase Date, then, with respect to any Note in respect of which the holder thereof shall
have submitted a Repurchase Notice, the interest payable on such Interest Payment Date shall be
paid to the holder of record of such Note on the applicable Record Date instead of the holder
surrendering such Note for repurchase. To exercise such right, the holder shall be required to
satisfy the conditions to such repurchase set forth in the Indenture and deliver to the Paying
Agent the Repurchase Notice set forth on the reverse hereof, at any time from the opening of
business on the date that is twenty (20) Business Days prior to the applicable Repurchase Date
until the close of business on the applicable 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 repurchase 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 a 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
cash and, if applicable, shares of Common Stock, with an aggregate value equal to the Conversion
Value as provided 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 pursuant to the terms
of the Indenture. The Conversion Rate shall initially be 35.2988 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 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) if the Issuer has specified a Fundamental Change Repurchase Date that is
after a Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent
of any overdue interest (including Additional Interest), if any exists at the time of conversion
with respect to this Note.

     In the event the holder surrenders this Note for conversion in connection with a Fundamental
Change occurring prior to January 15, 2011, the Issuer shall increase the applicable Conversion
Rate in accordance with the provisions of Section 13.13 of the Indenture unless the Issuer shall
have made a Public Acquiror Change of Control election in accordance with the provisions of Section
13.14 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

A-7

 

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)) 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 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

A-8

 

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.

     In addition to the rights provided to holders of Notes under the Indenture, holders shall have all
the rights set forth in the Registration Rights Agreement, dated as of December 19, 2005, between
the Issuer and the Initial Purchaser named therein.

     (a) Each Loan (other than Swingline Loans) shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their applicable Commitments; provided that the failure of any Lender to make
its Loan shall not in itself relieve any other Lender of its obligation to lend
hereunder (it being understood, however, that no Lender shall be responsible for
the failure of any other Lender to make any Loan required to be made by such
other Lender). Except for Loans deemed made pursuant to Section 2.18(e)(ii), (x)
ABR Loans comprising any Borrowing shall be in an aggregate principal amount
that is (i) an integral multiple of $500,000 and not less than $1.0 million or

<PAGE>

Borrower to repay such Loan in accordance with the terms of this Agreement.
Borrowings of more than one Type may be outstanding at the same time; provided
that Borrower shall not be entitled to request any Borrowing that, if made,
would result in more than eight Eurodollar Borrowings outstanding hereunder at
any one time. For purposes of the foregoing, Borrowings having different
Interest Periods, regardless of whether they commence on the same date, shall be
considered separate Borrowings.

          (c) Except with respect to Loans deemed made pursuant to Section
2.18(e)(ii), each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to such
account in New York City as the Administrative Agent may designate not later
than 11:00 a.m., New York City time, and the Administrative Agent shall promptly
credit the amounts so received to an account as directed by Borrower in the
applicable Borrowing Request maintained with the Administrative Agent or, if a
Borrowing shall not occur on such date because any condition precedent herein
specified shall not have been met, return the amounts so received to the
respective Lenders.

          (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above, and the Administrative Agent may, in
reliance upon such assumption, make available to Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available, then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, each of such Lender and Borrower
severally agrees to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to Borrower until the date such amount is repaid
to the Administrative Agent at (i) in the case of Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation. If such Lender shall repay to the Administrative
Agent such corresponding amount, such amount shall constitute such Lender's Loan
as part of such Borrowing for purposes of this Agreement, and Borrower's
obligation to repay the Administrative Agent such corresponding amount pursuant
to this Section 2.02(d) shall cease.

          (e) Notwithstanding any other provision of this Agreement, Borrower
shall not be entitled to request, or to elect to convert or continue, any
Borrowing if the Interest Period requested with respect thereto would end after
the Revolving Maturity Date or Term Loan Maturity Date, as applicable.

the failure of any Lender or the Administrative Agent to maintain such accounts
or any error therein shall not in any manner affect the obligations of Borrower
to repay the Loans in accordance with their terms.

          (c) Promissory Notes. Any Lender by written notice to Borrower (with a
copy to the Administrative Agent) may request that Loans of any Class made by it
be evidenced by a promissory note. In such event, Borrower shall prepare,
execute and deliver to such Lender a promissory note payable

                                      -42-

<PAGE>

to the order of such Lender (or, if requested by such Lender, to such Lender and
its registered assigns) in the form of Exhibit K-1, K-2 or K-3, as the case may
be. Thereafter, the Loans evidenced by such promissory note and interest thereon
shall at all times (including after assignment pursuant to Section 10.04) be
represented by one or more promissory notes in such form payable to the order of
the payee named therein (or, if such promissory note is a registered note, to
such payee and its registered assigns).

          SECTION 2.05 FEES.

          (a) Commitment Fee. Borrower agrees to pay to the Administrative Agent
for the account of each Lender a commitment fee (a "COMMITMENT FEE") equal to
the Applicable Fee per annum on the average daily unused amount of the Revolving
Commitment of such Lender during the period from and including the Closing Date.
Accrued Commitment Fees shall be payable in arrears (A) on the last Business Day
of March, June, September and December of each year, commencing on the first
such date to occur after the Closing Date, and (B) on the date on which such
Commitment terminates. Commitment Fees shall be computed on the basis of a year
of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). For purposes of computing
Commitment Fees, a Revolving Commitment of a Lender shall be deemed to be used
to the extent of the outstanding Revolving Loans and LC Exposure of such Lender
(and the Swingline Exposure of such Lender shall be disregarded for such
purpose).

          (b) Administrative Agent Fees. Borrower agrees to pay to the
Administrative Agent, for its own account, the administrative fees set forth in
the Original Fee Letter and the Amendment Fee Letter and/or such other fees
payable in the amounts and at the times separately agreed upon between Borrower
and the Administrative Agent (the "ADMINISTRATIVE AGENT FEES").

          (c) LC and Fronting Fees. Borrower agrees to pay (i) to the
Administrative Agent for the account of each Revolving Lender a participation
fee ("LC PARTICIPATION FEE") with respect to its participations in Letters of
Credit, which shall accrue at a rate equal to the Applicable Margin from time to
time used to determine the interest rate on Eurodollar Revolving Loans pursuant
to Section 2.06 on the average daily amount of such Lender's LC Exposure
(excluding any portion thereof attributable to Reimbursement Obligations) during
the period from and including the Closing Date to but excluding the later of the
date on which such Lender's Revolving Commitment terminates and the date on
which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a
fronting fee ("FRONTING FEE"), which shall accrue at the rate of 0.125% per
annum on the average daily amount of the LC Exposure (excluding any portion
thereof attributable to Reimbursement Obligations) during the period from and
including the Closing Date to but excluding the later of the date of termination
of the Revolving Commitments and the date on which there ceases to be any LC
Exposure, as well as the Issuing Bank's customary fees with respect to the
issuance, amendment, renewal or extension of any Letter of Credit or processing
of drawings thereunder. Accrued LC Participation Fees and Fronting Fees shall be
payable in arrears (i) on the last Business Day of March, June, September and
December of each year, commencing on the first such date to occur after the
Closing Date, and (ii) on the date on which the Revolving Commitments terminate.
Any such fees accruing after the date on which the Revolving Commitments
terminate shall be payable on demand. Any other fees payable to the Issuing Bank
pursuant to this paragraph shall be payable within 10 days after demand
therefor. All LC Participation Fees and Fronting Fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

          (d) All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, except that Borrower

                                      -43-

<PAGE>

shall pay the Fronting Fees directly to the Issuing Bank. Once paid, none of the
Fees shall be refundable under any circumstances.

          SECTION 2.06 INTEREST ON LOANS.

          (a) ABR Loans. Subject to the provisions of Section 2.06(c), the Loans
comprising each ABR Borrowing, including each Swingline Loan, shall bear
interest at a rate per annum equal to the Alternate Base Rate plus the
Applicable Margin in effect from time to time.

          (b) Eurodollar Loans. Subject to the provisions of Section 2.06(c),
the Loans comprising each Eurodollar Borrowing shall bear interest at a rate per
annum equal to the Adjusted LIBOR Rate for the Interest Period in effect for
such Borrowing plus the Applicable Margin in effect from time to time.

          (c) Default Rate. Notwithstanding the foregoing, during the
continuance of an Event of Default, all Obligations shall, to the extent
permitted by applicable law, bear interest, after as well as before judgment, at
a per annum rate equal to (i) in the case of principal of or interest on any
Loan, 2% plus the rate otherwise applicable to such Loan as provided in the
preceding paragraphs of this Section 2.06 or (ii) in the case of any other
amount, 2% plus the rate otherwise applicable to such amount (in either case,
the "DEFAULT RATE").

          (d) Interest Payment Dates. Accrued interest on each Loan shall be
payable in arrears on each Interest Payment Date for such Loan; provided that
(i) interest accrued pursuant to Section 2.06(c) shall be payable on demand,
(ii) in the event of any repayment or prepayment of any Loan (other than a
prepayment of an ABR Revolving Loan or a Swingline Loan), accrued interest on
the principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment and (iii) in the event of any conversion of any
Eurodollar Loan prior to the end of the current Interest Period therefor,
accrued interest on such Loan shall be payable on the effective date of such
conversion.

          (e) Interest Calculation. All interest hereunder shall be computed on
the basis of a year of 360 days, except that interest computed by reference to
the Alternate Base Rate shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The
applicable Alternate Base Rate or Adjusted LIBOR Rate shall be determined by the
Administrative Agent in accordance with the provisions of this Agreement and
such determination shall be conclusive absent manifest error.

          SECTION 2.07 TERMINATION AND REDUCTION OF COMMITMENTS.

          (a) Termination of Commitments. The New Term Loan Commitments existing
on the Amendment Effectiveness Date shall automatically terminate at 5:00 p.m.,
New York City time, on December 15, 2005. The Revolving Commitments, the
Swingline Commitment and the LC Commitment shall automatically terminate on the
Revolving Maturity Date.

          (b) Optional Terminations and Reductions. At its option, Borrower may
at any time terminate, or from time to time permanently reduce, the Commitments
of any Class; provided that (i) each reduction of the Commitments of any Class
shall be in an amount that is an integral multiple of $500,000 and not less than
$1.0 million and (ii) the Revolving Commitments shall not be terminated or
reduced if, after giving effect to any concurrent prepayment of the Revolving
Loans in accordance with Section 2.10,

                                      -44-

<PAGE>

the aggregate amount of Revolving Exposures would exceed the aggregate amount of
Revolving Commitments.

          (c) Borrower Notice. Borrower shall notify the Administrative Agent in
writing of any election to terminate or reduce the Commitments under Section
2.07(b) at least three Business Days prior to the effective date of such
termination or reduction, specifying such election and the effective date
thereof. Promptly following receipt of any notice, the Administrative Agent
shall advise the Lenders of the contents thereof. Each notice delivered by
Borrower pursuant to this Section shall be irrevocable; provided that a notice
of termination of the Commitments delivered by Borrower may state that such
notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by Borrower (by notice to the
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. Any termination or reduction of the Commitments of
any Class shall be permanent. Each reduction of the Commitments of any Class
shall be made ratably among the Lenders in accordance with their respective
Commitments of such Class.

          SECTION 2.08 INTEREST ELECTIONS.

          (a) Generally. Each Revolving Borrowing and Term Borrowing initially
shall be of the Type specified in the applicable Borrowing Request and, in the
case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request. Thereafter, Borrower may elect to convert
such Borrowing to a different Type or to continue such Borrowing and, in the
case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as
provided in this Section. Borrower may elect different options with respect to
different portions of the affected Borrowing, in which case each such portion
shall be allocated ratably among the Lenders holding the Loans comprising such
Borrowing, and the Loans comprising each such portion shall be considered a
separate Borrowing. Notwithstanding anything to the contrary, Borrower shall not
be entitled to request any conversion or continuation that, if made, would
result in more than eight Eurodollar Borrowings outstanding hereunder at any one
time. This Section shall not apply to Swingline Borrowings, which may not be
converted or continued.

          (b) Interest Election Notice. To make an election pursuant to this
Section, Borrower shall deliver, by hand delivery or telecopier, a duly
completed and executed Interest Election Request to the Administrative Agent not
later than the time that a Borrowing Request would be required under Section
2.03 if Borrower were requesting a Revolving Borrowing or Term Borrowing of the
Type resulting from such election to be made on the effective date of such
election. Each Interest Election Request shall be irrevocable. Each Interest
Election Request shall specify the following information in compliance with
Section 2.02:

          (i) the Borrowing to which such Interest Election Request applies and,
     if different options are being elected with respect to different portions
     thereof, or if outstanding Borrowings are being combined, allocation to
     each resulting Borrowing (in which case the information to be specified
     pursuant to clauses (iii) and (iv) below shall be specified for each
     resulting Borrowing);

          (ii) the effective date of the election made pursuant to such Interest
     Election Request, which shall be a Business Day;

          (iii) whether the resulting Borrowing is to be an ABR Borrowing or a
     Eurodollar Borrowing; and

                                      -45-

<PAGE>

          (iv) if the resulting Borrowing is a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period".

          If any such Interest Election Request requests a Eurodollar Borrowing
but does not specify an Interest Period, then Borrower shall be deemed to have
selected an Interest Period of one month's duration.

          Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

          (c) Automatic Conversion to ABR Borrowing. If an Interest Election
Request with respect to a Eurodollar Borrowing is not timely delivered prior to
the end of the Interest Period applicable thereto, then, unless such Borrowing
is repaid as provided herein, at the end of such Interest Period such Borrowing
shall be converted to an ABR Borrowing. Notwithstanding any contrary provision
hereof, if an Event of Default has occurred and is continuing, the
Administrative Agent or the Required Lenders may require, by notice to Borrower,
that (i) no outstanding Borrowing may be converted to or continued as a
Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be
converted to an ABR Borrowing at the end of the Interest Period applicable
thereto.

          SECTION 2.09 [INTENTIONALLY OMITTED].

          SECTION 2.10 OPTIONAL AND MANDATORY PREPAYMENTS OF LOANS.

          (a) Optional Prepayments. Borrower shall have the right at any time
and from time to time to prepay any Borrowing, in whole or in part, subject to
the requirements of this Section 2.10; provided that each partial prepayment
shall be in an amount that is an integral multiple of $500,000 and not less than
$1.0 million.

          (b) Revolving Loan Prepayments.

          (i) In the event of the termination of all the Revolving Commitments,
Borrower shall, on the date of such termination, repay or prepay all its
outstanding Revolving Borrowings and all outstanding Swingline Loans and replace
all outstanding Letters of Credit or cash collateralize all outstanding Letters
of Credit in accordance with the procedures set forth in Section 2.18(i).

          (ii) In the event of any partial reduction of the Revolving
Commitments, then (x) at or prior to the effective date of such reduction, the
Administrative Agent shall notify Borrower and the Revolving Lenders of the sum
of the Revolving Exposures after giving effect thereto and (y) if the sum of the
Revolving Exposures would exceed the aggregate amount of Revolving Commitments
after giving effect to such reduction, then Borrower shall, on the date of such
reduction, first, repay or prepay Swingline Loans, second, repay or prepay
Revolving Borrowings and third, replace outstanding Letters of Credit or cash
collateralize outstanding Letters of Credit in accordance with the procedures
set forth in Section 2.18(i), in an aggregate amount sufficient to eliminate
such excess.

          (iii) In the event that the sum of all Lenders' Revolving Exposures
exceeds the Revolving Commitments then in effect, Borrower shall, without notice
or demand, immediately first, repay or prepay Revolving Borrowings, and second,
replace outstanding Letters of Credit or cash collateralize outstanding Letters
of Credit in accordance with the procedures set forth in Section 2.18(i), in an
aggregate amount sufficient to eliminate such excess.

                                      -46-

<PAGE>

          (iv) In the event that the aggregate LC Exposure exceeds the LC
Commitment then in effect, Borrower shall, without notice or demand, immediately
replace outstanding Letters of Credit or cash collateralize outstanding Letters
of Credit in accordance with the procedures set forth in Section 2.18(i), in an
aggregate amount sufficient to eliminate such excess.

          (c) Asset Sales. Not later than five Business Days following the
receipt of any Net Cash Proceeds of any Asset Sale by Holdings or any of its
Subsidiaries, Borrower shall make prepayments in accordance with Sections
2.10(h) and (i) in an aggregate amount equal to 100% of such Net Cash Proceeds;
provided that:

          (i) no such prepayment shall be required under this Section 2.10(c)
     with respect to (A) any Asset Sale permitted by Sections 6.06(a), (c)-(h),
     (j) and (k), (B) the disposition of property which constitutes a Casualty
     Event, or (C) Asset Sales for fair market value resulting in no more than
     $1.0 million in Net Cash Proceeds per Asset Sale (or series of related
     Asset Sales) and less than $2.0 million in Net Cash Proceeds in any fiscal
     year; and

          (ii) so long as no Default shall then exist or would arise therefrom,
     such proceeds shall not be required to be so applied on such date to the
     extent that Borrower shall have delivered an Officers' Certificate to the
     Administrative Agent on or prior to such date stating that such Net Cash
     Proceeds are expected to be reinvested in fixed or capital assets within
     360 days following the date of such Asset Sale (which Officers' Certificate
     shall set forth the estimates of the proceeds to be so expended); provided
     that if all or any portion of such Net Cash Proceeds is not so reinvested
     within such 360-day period, such unused portion shall be applied on the
     last day of such period as a mandatory prepayment as provided in this
     Section 2.10(c); provided, further, that if the property subject to such
     Asset Sale constituted Collateral, then all property purchased with the Net
     Cash Proceeds thereof pursuant to this subsection shall be made subject to
     the Lien of the applicable Security Documents in favor of the Collateral
     Agent, for its benefit and for the benefit of the other Secured Parties in
     accordance with Sections 5.11 and 5.12.

          (d) Debt Issuance or Preferred Stock Issuance. Not later than five
Business Days following the receipt of any Net Cash Proceeds of any Debt
Issuance or Preferred Stock Issuance by Holdings or any of its Subsidiaries,
Borrower shall make prepayments in accordance with Sections 2.10(h) and (i) in
an aggregate amount equal to 100% of such Net Cash Proceeds.

          (e) Equity Issuance. Not later than five Business Days following the
receipt by any Parent Company or its Subsidiaries of any Net Cash Proceeds of
any Equity Issuance, Borrower shall make prepayments in accordance with Sections
2.10(h) and (i) in an aggregate amount equal to 50% of such Net Cash Proceeds.

          (f) Casualty Events. Not later than seven Business Days following the
receipt of any Net Cash Proceeds from a Casualty Event by Holdings or any of its
Subsidiaries, Borrower shall make prepayments in accordance with Sections
2.10(h) and (i) in an aggregate amount equal to 100% of such Net Cash Proceeds;
provided that:

          (i) so long as no Default shall then exist or arise therefrom, such
     proceeds shall not be required to be so applied on such date to the extent
     that Borrower shall have delivered an Officers' Certificate to the
     Administrative Agent on or prior to such date stating that such proceeds
     are expected to be used to repair, replace or restore any property in
     respect of which such Net Cash Proceeds were paid or to reinvest in other
     fixed or capital assets, no later than 360 days following

                                      -47-

<PAGE>

     the date of receipt of such proceeds; provided that so long as
     construction or other work to so replace, repair or restore has commenced
     within such 360-day period but has not been completed (and can reasonably
     be expected to be completed pursuant to a written contract to be completed
     within 540 days of receipt), any such remaining proceeds shall continue to
     not be required to be so applied so long as they are used to repay any
     outstanding Revolving Loans; provided further that if the property subject
     to such Casualty Event constituted Collateral under the Security Documents,
     then all property purchased with the Net Cash Proceeds thereof pursuant to
     this subsection shall be made subject to the Lien of the applicable
     Security Documents in favor of the Collateral Agent, for its benefit and
     for the benefit of the other Secured Parties in accordance with Sections
     5.11 and 5.12; and

          (ii) if any portion of such Net Cash Proceeds shall not be so applied
     within such 360-day period (or 540-day period, as applicable), such unused
     portion shall be applied on the last day of such period as a mandatory
     prepayment as provided in this Section 2.10(f).

          (g) Excess Cash Flow. No later than the earlier of (i) 90 days after
the end of each Excess Cash Flow Period and (ii) the date on which the financial
statements with respect to such fiscal year in which such Excess Cash Flow
Period occurs are delivered pursuant to Section 5.01(a), Borrower shall make
prepayments in accordance with Sections 2.10(h) and (i) in an aggregate amount
equal to 75% of Excess Cash Flow for the Excess Cash Flow Period then ended;
provided that if the Total Leverage Ratio as of the end of any Excess Cash Flow
Period is less than 4.0:1.0, then only 50% of Excess Cash Flow for such Excess
Cash Flow Period shall be required to be applied toward such prepayments.

          (h) Application of Prepayments. Prior to any optional or mandatory
prepayment hereunder, Borrower shall select the Borrowing or Borrowings to be
prepaid and shall specify such selection in the notice of such prepayment
pursuant to Section 2.10(i), subject to the provisions of this Section 2.10(h).
After application of mandatory prepayments of Term Loans described above in this
Section 2.10(h) and to the extent there are mandatory prepayment amounts
remaining after such application, the Revolving Commitments shall be permanently
reduced ratably among the Revolving Lenders in accordance with their applicable
Revolving Commitments in an aggregate amount equal to such excess, and Borrower
shall comply with Section 2.10(b).

          Amounts to be applied pursuant to this Section 2.10 to the prepayment
of Term Loans and Revolving Loans shall be applied, as applicable, first to
reduce outstanding ABR Term Loans and ABR Revolving Loans, respectively. Any
amounts remaining after each such application shall be applied to prepay
Eurodollar Term Loans or Eurodollar Revolving Loans, as applicable.
Notwithstanding the foregoing, if the amount of any prepayment of Loans required
under this Section 2.10 shall be in excess of the amount of the ABR Loans at the
time outstanding (an "EXCESS AMOUNT"), only the portion of the amount of such
prepayment as is equal to the amount of such outstanding ABR Loans shall be
immediately prepaid and, at the election of Borrower, the Excess Amount shall be
either (A) deposited in an escrow account on terms satisfactory to the
Collateral Agent and applied to the prepayment of Eurodollar Loans on the last
day of the then next-expiring Interest Period for Eurodollar Loans; provided
that (i) interest in respect of such Excess Amount shall continue to accrue
thereon at the rate provided hereunder for the Loans which such Excess Amount is
intended to repay until such Excess Amount shall have been used in full to repay
such Loans and (ii) at any time while an Event of Default has occurred and is
continuing, the Administrative Agent may, and upon written direction from the
Required Lenders shall, apply any or all proceeds then on deposit to the payment
of such Loans in an amount equal to such Excess Amount or (B) prepaid
immediately, together with any amounts owing to the Lenders under Section 2.13.

                                      -48-

<PAGE>

          (i) Notice of Prepayment. Borrower shall notify the Administrative
Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender)
by written notice of any prepayment hereunder (i) in the case of prepayment of a
Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three
Business Days before the date of prepayment, (ii) in the case of prepayment of
an ABR Borrowing, not later than four hours (during the normal Business Day)
prior to such prepayment and (iii) in the case of prepayment of a Swingline
Loan, not later than 11:00 a.m., New York City time, on the date of prepayment.
Each such notice shall be irrevocable; provided that, if a notice of prepayment
is given in connection with a conditional notice of termination of the
Commitments as contemplated by Section 2.07, then such notice of prepayment may
be revoked if such termination is revoked in accordance with Section 2.07. Each
such notice shall specify the prepayment date, the principal amount of each
Borrowing or portion thereof to be prepaid and, in the case of a mandatory
prepayment, a reasonably detailed calculation of the amount of such prepayment.
Promptly following receipt of any such notice (other than a notice relating
solely to Swingline Loans), the Administrative Agent shall advise the Lenders of
the contents thereof. Each partial prepayment of any Borrowing shall be in an
amount that would be permitted in the case of a Credit Extension of the same
Type as provided in Section 2.02, except as necessary to apply fully the
required amount of a mandatory prepayment. Each prepayment of a Borrowing shall
be applied ratably to the Loans included in the prepaid Borrowing and otherwise
in accordance with this Section 2.10. Prepayments shall be accompanied by
accrued interest to the extent required by Section 2.06.

          SECTION 2.11 ALTERNATE RATE OF INTEREST. If prior to the commencement
of any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be
     final and conclusive absent manifest error) that adequate and reasonable
     means do not exist for ascertaining the Adjusted LIBOR Rate for such
     Interest Period; or

          (b) the Administrative Agent is advised in writing by the Required
     Lenders that the Adjusted LIBOR Rate for such Interest Period will not
     adequately and fairly reflect the cost to such Lenders of making or
     maintaining their Loans included in such Borrowing for such Interest
     Period;

then the Administrative Agent shall give written notice thereof to Borrower and
the Lenders as promptly as practicable thereafter and, until the Administrative
Agent notifies Borrower and the Lenders that the circumstances giving rise to
such notice no longer exist (which notice shall be promptly given), (i) any
Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing.

          SECTION 2.12 YIELD PROTECTION.

          (a) Increased Costs Generally. If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit,
     compulsory loan, insurance charge or similar requirement against assets of,
     deposits with or for the account of, or credit extended or participated in,
     by any Lender (except any reserve requirement reflected in the Adjusted
     LIBOR Rate) or the Issuing Bank;

          (ii) subject any Lender or the Issuing Bank to any tax of any kind
     whatsoever with respect to this Agreement, any Letter of Credit, any
     participation in a Letter of Credit or any Loan

                                      -49-

<PAGE>

     made by it, or change the basis of taxation of payments to such Lender or
     the Issuing Bank in respect thereof (except for Indemnified Taxes or Other
     Taxes covered by Section 2.15 and the imposition of, or any change in the
     rate of, any Excluded Tax payable by such Lender or the Issuing Bank); or

          (iii) impose on any Lender or the Issuing Bank or the London interbank
     market any other condition, cost or expense (excluding Taxes) affecting
     this Agreement or Eurodollar Loans made by such Lender or any Letter of
     Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan), or to increase the cost to such Lender, the
Issuing Bank or such Lender's or the Issuing Bank's holding company, if any, of
participating in, issuing or maintaining any Letter of Credit (or of maintaining
its obligation to participate in or to issue any Letter of Credit), or to reduce
the amount of any sum received or receivable by such Lender or the Issuing Bank
hereunder (whether of principal, interest or any other amount), then, upon
request of such Lender or the Issuing Bank, Borrower will pay to such Lender or
the Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Bank, as the case may be, for such
additional costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or the Issuing Bank determines
(in good faith, but in its sole absolute discretion) that any Change in Law
affecting such Lender or the Issuing Bank or any lending office of such Lender
or such Lender's or the Issuing Bank's holding company, if any, regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's or the Issuing Bank's capital or on the capital of such
Lender's or the Issuing Bank's holding company, if any, as a consequence of this
Agreement, the Commitments of such Lender or the Loans made by, or
participations in Letters of Credit held by, such Lender, or the Letters of
Credit issued by the Issuing Bank, to a level below that which such Lender or
the Issuing Bank or such Lender's or the Issuing Bank's holding company could
have achieved but for such Change in Law (taking into consideration such
Lender's or the Issuing Bank's policies and the policies of such Lender's or the
Issuing Bank's holding company with respect to capital adequacy), then from time
to time Borrower will pay to such Lender or the Issuing Bank, as the case may
be, such additional amount or amounts as will compensate such Lender or the
Issuing Bank or such Lender's or the Issuing Bank's holding company for any such
reduction suffered.

          (c) Certificates for Reimbursement. A certificate of a Lender or the
Issuing Bank setting forth in reasonable detail the amount or amounts necessary
to compensate such Lender or the Issuing Bank or its holding company, as the
case may be, as specified in paragraph (a) or (b) of this Section 2.12 and
delivered to Borrower shall be conclusive absent manifest error. Subject to
Section 2.12(d), Borrower shall pay such Lender or the Issuing Bank, as the case
may be, the amount shown as due on any such certificate within 10 days after
receipt thereof.

          (d) Delay in Requests. Failure or delay on the part of any Lender or
the Issuing Bank to demand compensation pursuant to this Section 2.12 shall not
constitute a waiver of such Lender's or the Issuing Bank's right to demand such
compensation; provided that Borrower shall not be required to compensate a
Lender or the Issuing Bank pursuant to this Section for any increased costs
incurred or reductions suffered more than six months prior to the date that such
Lender or the Issuing Bank, as the case may be, notifies Borrower of the Change
in Law giving rise to such increased costs or reductions and of such Lender's or
the Issuing Bank's intention to claim compensation therefor (except that, if the
Change

                                      -50-

<PAGE>

in Law giving rise to such increased costs or reductions is retroactive, then
the six-month period referred to above shall be extended to include the period
of retroactive effect thereof).

          SECTION 2.13 BREAKAGE PAYMENTS. In the event of (a) the payment or
prepayment, whether optional or mandatory, of any principal of any Eurodollar
Loan earlier than the last day of an Interest Period applicable thereto
(including as a result of an Event of Default), (b) the conversion of any
Eurodollar Loan earlier than the last day of the Interest Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Revolving
Loan or Term Loan on the date specified in any notice delivered pursuant hereto
or (d) the assignment of any Eurodollar Loan earlier than the last day of the
Interest Period applicable thereto as a result of a request by Borrower pursuant
to Section 2.16(b), then, in any such event, Borrower shall compensate each
Lender for the loss, cost and expense attributable to such event. In the case of
a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to
include an amount determined by such Lender to be the excess, if any, of (i) the
amount of interest which would have accrued on the principal amount of such Loan
had such event not occurred, at the Adjusted LIBOR Rate that would have been
applicable to such Loan, for the period from the date of such event to the last
day of the then current Interest Period therefor (or, in the case of a failure
to borrow, convert or continue, for the period that would have been the Interest
Period for such Loan), over (ii) the amount of interest which would accrue on
such principal amount for such period at the interest rate which such Lender
would bid were it to bid, at the commencement of such period, for dollar
deposits of a comparable amount and period from other banks in the Eurodollar
market. A certificate of any Lender setting forth in reasonable detail any
amount or amounts that such Lender is entitled to receive pursuant to this
Section 2.13 shall be delivered to Borrower (with a copy to the Administrative
Agent) and shall be conclusive and binding absent manifest error. Borrower shall
pay such Lender the amount shown as due on any such certificate within 5 days
after receipt thereof.

          SECTION 2.14 PAYMENTS GENERALLY; PRO RATA TREATMENT; SHARING OF
SETOFFS.

          (a) Payments Generally. Borrower shall make each payment required to
be made by it hereunder or under any other Loan Document (whether of principal,
interest, fees or Reimbursement Obligations, or of amounts payable under Section
2.12, 2.13, 2.15 or 10.03, or otherwise) on or before the time expressly
required hereunder or under such other Loan Document for such payment (or, if no
such time is expressly required, prior to 2:00 p.m., New York City time), on the
date when due, in immediately available funds, without setoff, deduction or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Administrative Agent, be deemed to have been received on the
next succeeding Business Day for purposes of calculating interest thereon. All
such payments shall be made to the Administrative Agent at its offices at 677
Washington Boulevard, Stamford, Connecticut, except payments to be made directly
to the Issuing Bank or Swingline Lender as expressly provided herein and except
that payments pursuant to Sections 2.12, 2.13, 2.15 and 10.03 shall be made
directly to the persons entitled thereto and payments pursuant to other Loan
Documents shall be made to the persons specified therein. The Administrative
Agent shall distribute any such payments received by it for the account of any
other person to the appropriate recipient promptly following receipt thereof. If
any payment under any Loan Document shall be due on a day that is not a Business
Day, unless specified otherwise, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
under each Loan Document shall be made in dollars, except as expressly specified
otherwise.

          (b) Insufficient Funds. If at any time insufficient funds are received
by and available to the Administrative Agent to pay fully all amounts of
principal, Reimbursement Obligations, interest and fees then due hereunder, such
funds shall be applied (i) first, toward payment of interest and fees then

                                      -51-

<PAGE>

due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, and (ii) second, toward
payment of principal and Reimbursement Obligations then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of principal
and Reimbursement Obligations then due to such parties.

          (c) Sharing of Setoff. If any Lender (and/or the Issuing Bank, which
shall be deemed a "Lender" for purposes of this Section 2.14(c)) shall, by
exercising any right of setoff or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Loans or other Obligations
resulting in such Lender's receiving payment of a proportion of the aggregate
amount of its Loans and accrued interest thereon or other Obligations greater
than its pro rata share thereof as provided herein, then the Lender receiving
such greater proportion shall (a) notify the Administrative Agent of such fact,
and (b) purchase (for cash at face value) participations in the Loans and such
other obligations of the other Lenders, or make such other adjustments as shall
be equitable, so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and other amounts owing them,
provided that:

          (i) if any such participations are purchased and all or any portion of
     the payment giving rise thereto is recovered, such participations shall be
     rescinded and the purchase price restored to the extent of such recovery,
     without interest; and

          (ii) the provisions of this paragraph shall not be construed to apply
     to (x) any payment made by Borrower pursuant to and in accordance with the
     express terms of this Agreement or (y) any payment obtained by a Lender as
     consideration for the assignment of or sale of a participation in any of
     its Loans or participations in LC Disbursements to any assignee or
     participant, other than to Borrower or any Subsidiary thereof (as to which
     the provisions of this paragraph shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may
effectively do so under applicable Requirements of Law, that any Lender
acquiring a participation pursuant to the foregoing arrangements may exercise
against such Loan Party rights of setoff and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Loan
Party in the amount of such participation. If under applicable bankruptcy,
insolvency or any similar law any Secured Party receives a secured claim in lieu
of a setoff or counterclaim to which this Section 2.14(c) applies, such Secured
Party shall to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights to which the Secured Party
is entitled under this Section 2.14(c) to share in the benefits of the recovery
of such secured claim.

          (d) Borrower Default. Unless the Administrative Agent shall have
received notice from Borrower prior to the date on which any payment is due to
the Administrative Agent for the account of the Lenders or the Issuing Bank
hereunder that Borrower will not make such payment, the Administrative Agent may
assume that Borrower has made such payment on such date in accordance herewith
and may, in reliance upon such assumption, distribute to the Lenders or the
Issuing Bank, as the case may be, the amount due. In such event, if Borrower has
not in fact made such payment, then each of the Lenders or the Issuing Bank, as
the case may be, severally agrees to repay to the Administrative Agent forthwith
on demand the amount so distributed to such Lender or the Issuing Bank with
interest thereon, for each day from and including the date such amount is
distributed to it to but excluding the date of payment to the Administrative
Agent, at the greater of the Federal Funds Effective Rate and a rate determined
by the Administrative Agent in accordance with banking industry rules on
interbank compensation.

                                      -52-

<PAGE>

          (e) Lender Default. If any Lender shall fail to make any payment
required to be made by it pursuant to Section 2.02(c), 2.14(d), 2.17(d),
2.18(d), 2.18(e) or 10.03(c), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender's obligations under such Sections until all such
unsatisfied obligations are fully paid.

          SECTION 2.15 TAXES.

          (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of Borrower hereunder or under any other Loan Document shall be
made free and clear of and without reduction or withholding for any Indemnified
Taxes or Other Taxes; provided that if Borrower shall be required by applicable
Requirements of Law to deduct any Indemnified Taxes (including any Other Taxes)
from such payments, then (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or
Issuing Bank, as the case may be, receives an amount equal to the sum it would
have received had no such deductions been made, (ii) Borrower shall make such
deductions and (iii) Borrower shall timely pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable Requirements of
Law.

          (b) Payment of Other Taxes by Borrower. Without limiting the
provisions of paragraph (a) above, Borrower shall timely pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable Requirements
of Law.

          (c) Indemnification by Borrower. Borrower shall indemnify the
Administrative Agent, each Lender and the Issuing Bank, within 20 days after
demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) paid by the Administrative
Agent, such Lender or the Issuing Bank, as the case may be, and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to
the amount of such payment or liability delivered to Borrower by a Lender or the
Issuing Bank (with a copy to the Administrative Agent), or by the Administrative
Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be
conclusive absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by Borrower to a Governmental Authority,
Borrower shall deliver to the Administrative Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

          (e) Status of Lenders. Any Foreign Lender shall, to the extent it may
lawfully do so, deliver to Borrower and the Administrative Agent (in such number
of copies as shall be requested by the recipient) on or prior to the date on
which such Foreign Lender becomes a Lender under this Agreement (and from time
to time thereafter upon the request of Borrower or the Administrative Agent or
if the Lender's factual or legal circumstances have changed since it last
provided the form, rendering such form obsolete or incorrect, but only if such
Foreign Lender is legally entitled to do so), whichever of the following is
applicable:

                                      -53-

<PAGE>

          (i) duly completed copies of Internal Revenue Service Form W-8BEN
     claiming eligibility for benefits of an income tax treaty to which the
     United States of America is a party,

          (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

          (iii) in the case of a Foreign Lender claiming the benefits of the
     exemption for portfolio interest under Section 881(c) of the Code, (x) a
     certificate, in substantially the form of Exhibit Q, or any other form
     approved by the Administrative Agent, to the effect that such Foreign
     Lender is not (A) a "bank" within the meaning of Section 881(c)(3)(A) of
     the Code, (B) a "10 percent shareholder" of Borrower within the meaning of
     Section 881(c)(3)(B) of the Code, or (C) a "controlled foreign corporation"
     described in Section 881(c)(3)(C) of the Code and (y) duly completed copies
     of Internal Revenue Service Form W-8BEN, or

          (iv) any other form prescribed by applicable Requirements of Law as a
     basis for claiming exemption from or a reduction in United States Federal
     withholding tax duly completed together with such supplementary
     documentation as may be prescribed by applicable Requirements of Law to
     permit Borrower to determine the withholding or deduction required to be
     made.

          (f) Treatment of Certain Refunds. If the Administrative Agent, a
Lender or the Issuing Bank determines, in its good faith sole discretion, that
it has received a refund of any Indemnified Taxes or Other Taxes as to which it
has been indemnified by Borrower or with respect to which Borrower has paid
additional amounts pursuant to this Section, it shall pay to Borrower an amount
equal to such refund (but only to the extent of indemnity payments made, or
additional amounts paid, by Borrower under this Section with respect to the
Indemnified Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing
Bank, as the case may be, and without interest (other than any interest paid by
the relevant Governmental Authority with respect to such refund) so as to leave
such Lender, Issuing Bank or Administrative Agent in no better or worse position
than in which each would have been if payment of the relevant additional amount
had not been made; provided that Borrower, upon the request of the
Administrative Agent, such Lender or the Issuing Bank, agrees to repay the
amount paid over to Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent,
such Lender or the Issuing Bank in the event the Administrative Agent, such
Lender or the Issuing Bank is required to repay such refund to such Governmental
Authority. This paragraph shall not be construed to require the Administrative
Agent, any Lender or the Issuing Bank to make available its tax returns (or any
other information relating to its taxes that it deems confidential) to Borrower
or any other person.

          SECTION 2.16 MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.

          (a) Designation of a Different Lending Office. If any Lender requests
compensation under Section 2.12, or requires Borrower to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.15, then such Lender shall use reasonable efforts to
designate a different lending office for funding or booking its Loans hereunder
or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section
2.12 or 2.15, as the case may be and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. Borrower hereby agrees to pay all reasonable costs and expenses incurred
by any Lender in connection with any such designation or assignment. A
certificate setting forth such costs and expenses submitted by such Lender to
Borrower shall be conclusive absent manifest error.

                                      -54-

<PAGE>

          (b) Replacement of Lenders. If any Lender requests compensation under
Section 2.12, or if Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.15, or if any Lender defaults in its obligation to fund Loans
hereunder, or if Borrower exercises its replacement rights under Section
10.02(d), then Borrower may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in, and consents required by, Section 10.04), all of its interests, rights and
obligations under this Agreement and the other Loan Documents to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that:

          (i) Borrower shall have paid to the Administrative Agent the
     processing and recordation fee specified in Section 10.04(b);

          (ii) such Lender shall have received payment of an amount equal to the
     outstanding principal of its Loans and participations in LC Disbursements
     and Swingline Loans, accrued interest thereon, accrued fees and all other
     amounts payable to it hereunder and under the other Loan Documents
     (including any amounts under Section 2.13), from the assignee (to the
     extent of such outstanding principal and accrued interest and fees) or
     Borrower (in the case of all other amounts);

          (iii) in the case of any such assignment resulting from a claim for
     compensation under Section 2.12 or payments required to be made pursuant to
     Section 2.15, such assignment will result in a reduction in such
     compensation or payments thereafter; and

          (iv) such assignment does not conflict with applicable Requirements of
     Law.

A Lender shall not be required to make any such assignment or delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling Borrower to require such assignment and delegation cease
to apply.

          SECTION 2.17 SWINGLINE LOANS.

          (a) Swingline Commitment. Subject to the terms and conditions set
forth herein, the Swingline Lender agrees to make Swingline Loans to Borrower
from time to time during the Revolving Availability Period, in an aggregate
principal amount at any time outstanding that will not result in (i) the
aggregate principal amount of outstanding Swingline Loans exceeding $10,000,000
or (ii) the sum of the total Revolving Exposures exceeding the total Revolving
Commitments; provided that the Swingline Lender shall not be required to make a
Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing
limits and subject to the terms and conditions set forth herein, Borrower may
borrow, repay and reborrow Swingline Loans.

          (b) Swingline Loans. To request a Swingline Loan, Borrower shall
deliver, by hand delivery or telecopier, a duly completed and executed Borrowing
Request to the Administrative Agent and the Swingline Lender, not later than
2:00 p.m., New York City time, on the day of a proposed Swingline Loan. Each
such notice shall be irrevocable and shall specify the requested date (which
shall be a Business Day) and the amount of the requested Swingline Loan. Each
Swingline Loan shall be an ABR Loan. The Swingline Lender shall make each
Swingline Loan available to Borrower by means of a credit to the general deposit
account of Borrower with the Swingline Lender (or, in the case of a Swingline
Loan made to finance the reimbursement of an LC Disbursement as provided in
Section

                                      -55-

<PAGE>

2.18(e), by remittance to the Issuing Bank) by 3:00 p.m., New York City time, on
the requested date of such Swingline Loan. Borrower shall not request a
Swingline Loan if at the time of or immediately after giving effect to the
Extension of Credit contemplated by such request a Default has occurred and is
continuing or would result therefrom. Swingline Loans shall be made in minimum
amounts of $500,000 and integral multiples of $500,000 above such amount.

          (c) Prepayment. Borrower shall have the right at any time and from
time to time to repay any Swingline Loan, in whole or in part, upon giving
written notice to the Swingline Lender and the Administrative Agent before 12:00
(noon), New York City time, on the proposed date of repayment.

          (d) Participations. The Swingline Lender may at any time in its
discretion by written notice given to the Administrative Agent (provided such
notice requirement shall not apply if the Swingline Lender and the
Administrative Agent are the same entity) not later than 11:00 A.M., New York
City time, on the next succeeding Business Day following such notice require the
Revolving Lenders to acquire participations on such Business Day in all or a
portion of the Swingline Loans then outstanding. Such notice shall specify the
aggregate amount of Swingline Loans in which Revolving Lenders will participate.
Promptly upon receipt of such notice, the Administrative Agent will give notice
thereof to each Revolving Lender, specifying in such notice such Lender's Pro
Rata Percentage of such Swingline Loan or Loans. Each Revolving Lender hereby
absolutely and unconditionally agrees, upon receipt of notice as provided above,
to pay to the Administrative Agent, for the account of the Swingline Lender,
such Lender's Pro Rata Percentage of such Swingline Loan or Loans. Each
Revolving Lender acknowledges and agrees that its obligation to acquire
participations in Swingline Loans pursuant to this paragraph is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever (so long as such
payment shall not cause such Lender's Revolving Exposure to exceed such Lender's
Revolving Commitment). Each Revolving Lender shall comply with its obligation
under this paragraph by wire transfer of immediately available funds, in the
same manner as provided in Section 2.02(c) with respect to Loans made by such
Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment
obligations of the Revolving Lenders), and the Administrative Agent shall
promptly pay to the Swingline Lender the amounts so received by it from the
Revolving Lenders. The Administrative Agent shall notify Borrower of any
participations in any Swingline Loan acquired by the Revolving Lenders pursuant
to this paragraph, and thereafter payments in respect of such Swingline Loan
shall be made to the Administrative Agent and not to the Swingline Lender. Any
amounts received by the Swingline Lender from Borrower (or other party on behalf
of Borrower) in respect of a Swingline Loan after receipt by the Swingline
Lender of the proceeds of a sale of participations therein shall be promptly
remitted to the Administrative Agent. Any such amounts received by the
Administrative Agent shall be promptly remitted by the Administrative Agent to
the Revolving Lenders that shall have made their payments pursuant to this
paragraph, as their interests may appear. The purchase of participations in a
Swingline Loan pursuant to this paragraph shall not relieve Borrower of any
default in the payment thereof.

          SECTION 2.18 LETTERS OF CREDIT.

          (a) General. Subject to the terms and conditions set forth herein,
Borrower may request the Issuing Bank, and the Issuing Bank agrees, to issue
Letters of Credit for its own account or the account of a Subsidiary in a form
reasonably acceptable to the Administrative Agent and the Issuing Bank, at any
time and from time to time during the Revolving Availability Period (provided
that Borrower shall be a co-applicant, and be jointly and severally liable, with
respect to each Letter of Credit issued for the account of a Subsidiary). The
Issuing Bank shall have no obligation to issue, and Borrower

                                      -56-

<PAGE>

shall not request the issuance of, any Letter of Credit at any time if after
giving effect to such issuance, the LC Exposure would exceed the LC Commitment
or the total Revolving Exposure would exceed the total Revolving Commitments. In
the event of any inconsistency between the terms and conditions of this
Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by Borrower to, or entered into by
Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and
conditions of this Agreement shall control.

          (b) Request for Issuance, Amendment, Renewal, Extension; Certain
Conditions and Notices. To request the issuance of a Letter of Credit or the
amendment, renewal or extension of an outstanding Letter of Credit, Borrower
shall deliver, by hand or telecopier (or transmit by electronic communication,
if arrangements for doing so have been approved by the Issuing Bank), an LC
Request to the Issuing Bank and the Administrative Agent not later than 11:00
a.m. on the third Business Day preceding the requested date of issuance,
amendment, renewal or extension (or such later date and time as is acceptable to
the Issuing Bank).

          A request for an initial issuance of a Letter of Credit shall specify
in form and detail satisfactory to the Issuing Bank:

          (i) the proposed issuance date of the requested Letter of Credit
     (which shall be a Business Day);

          (ii) the amount thereof;

          (iii) the expiry date thereof (which shall not be later than the date
     specified in Section 2.18(c));

          (iv) the name and address of the beneficiary thereof;

          (v) whether the Letter of Credit is to be issued for its own account
     or for the account of one of its Subsidiaries (provided that Borrower shall
     be a co-applicant, and therefore jointly and severally liable, with respect
     to each Letter of Credit issued for the account of a Subsidiary);

          (vi) the documents to be presented by such beneficiary in connection
     with any drawing thereunder;

          (vii) the full text of any certificate to be presented by such
     beneficiary in connection with any drawing thereunder; and

          (viii) such other matters as the Issuing Bank may require.

          A request for an amendment, renewal or extension of any outstanding
Letter of Credit shall specify in form and detail satisfactory to the Issuing
Bank:

          (i) the Letter of Credit to be amended, renewed or extended;

          (ii) the proposed date of amendment, renewal or extension thereof
     (which shall be a Business Day);

          (iii) the nature of the proposed amendment, renewal or extension; and

                                      -57-

<PAGE>

          (iv) such other matters as the Issuing Bank may require.

If requested by the Issuing Bank, Borrower also shall submit a letter of credit
application on the Issuing Bank's standard form in connection with any request
for a Letter of Credit. In the event of any conflict between such application
and this Agreement, this Agreement shall control. A Letter of Credit shall be
issued, amended, renewed or extended only if (and, upon issuance, amendment,
renewal or extension of each Letter of Credit, Borrower shall be deemed to
represent and warrant that), after giving effect to such issuance, amendment,
renewal or extension, (i) the LC Exposure shall not exceed the LC Commitment,
(ii) the total Revolving Exposures shall not exceed the total Revolving
Commitments and (iii) the conditions set forth in Section 4.02 in respect of
such issuance, amendment, renewal or extension shall have been satisfied. Unless
the Issuing Bank shall agree otherwise, no Letter of Credit shall be in an
initial amount less than $100,000, in the case of a Commercial Letter of Credit,
or $500,000, in the case of a Standby Letter of Credit.

          Upon the issuance of any Letter of Credit or amendment, renewal,
extension or modification to a Letter of Credit, the Issuing Bank shall promptly
notify the Administrative Agent, who shall promptly notify each Revolving
Lender, thereof, which notice shall be accompanied by a copy of such Letter of
Credit or amendment, renewal, extension or modification to a Letter of Credit
and the amount of such Lender's respective participation in such Letter of
Credit pursuant to Section 2.18(d). On the first Business Day of each calendar
month, the Issuing Bank shall provide to the Administrative Agent a report
listing all outstanding Letters of Credit and the amounts and beneficiaries
thereof and the Administrative Agent shall promptly provide such report to each
Revolving Lender.

          (c) Expiration Date. (i) Each Letter of Credit shall expire at or
prior to the close of business on the earlier of (i) in the case of a Standby
Letter of Credit, (x) the date which is one year after the date of the issuance
of such Standby Letter of Credit (or, in the case of any renewal or extension
thereof, one year after such renewal or extension) and (y) the Letter of Credit
Expiration Date and (ii) in the case of a Commercial Letter of Credit, (x) the
date that is 270 days after the date of issuance of such Commercial Letter of
Credit (or, in the case of any renewal or extension thereof, 270 days after such
renewal or extension) and (y) the Letter of Credit Expiration Date.

          (ii) If Borrower so requests in any Letter of Credit Request, the
Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter
of Credit that has automatic renewal provisions (each, an "AUTO-RENEWAL LETTER
OF CREDIT"); provided that any such Auto-Renewal Letter of Credit must permit
the Issuing Bank to prevent any such renewal at least once in each twelve-month
period (commencing with the date of issuance of such Letter of Credit) by giving
prior notice to the beneficiary thereof not later than a day in each such
twelve-month period to be agreed upon at the time such Letter of Credit is
issued. Unless otherwise directed by the Issuing Bank, Borrower shall not be
required to make a specific request to the Issuing Bank for any such renewal.
Once an Auto-Renewal Letter of Credit has been issued, the Revolving Lenders
shall be deemed to have authorized (but may not require) the Issuing Bank to
permit the renewal of such Letter of Credit at any time to an expiry date not
later than the earlier of (i) one year from the date of such renewal and (ii)
the Letter of Credit Expiration Date; provided that the Issuing Bank shall not
permit any such renewal if (x) the Issuing Bank has determined that it would
have no obligation at such time to issue such Letter of Credit in its renewed
form under the terms hereof (by reason of the provisions of Section 2.18(f) or
otherwise), or (y) it has received notice on or before the day that is two
Business Days before the date which has been agreed upon pursuant to the proviso
of the first sentence of this paragraph, (1) from the Administrative Agent that
any Revolving Lender directly affected thereby has elected not to permit such
renewal or (2) from the Administrative Agent, any Lender or Borrower that one or
more of the applicable conditions specified in Section 4.02 are not then
satisfied.

          (d) Participations. By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Issuing Bank or the Lenders, the Issuing Bank
hereby irrevocably grants to each Revolving Lender, and each Revolving Lender
hereby acquires from the Issuing Bank, a participation in such Letter of Credit
equal to such Revolving Lender's Pro Rata Percentage of the aggregate amount
available to be drawn under such Letter of Credit. In consideration and in
furtherance of the foregoing, each Revolving Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of
the Issuing Bank, such Revolving Lender's Pro Rata Percentage of each LC
Disbursement made by the Issuing Bank and not reimbursed by Borrower on the date
due as provided in Section 2.18(e), or of any reimbursement payment required to
be refunded to Borrower for any reason. Each Revolving Lender acknowledges and
agrees that its obligation to acquire participations pursuant to this paragraph
in respect of Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or
extension of any Letter of Credit or the occurrence and continuance of a Default
or reduction or termination of the Commitments, or expiration, termination or
cash collateralization of any Letter of Credit and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement.

          (i) If the Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, Borrower shall reimburse such LC Disbursement by paying to the
Issuing Bank an amount equal to such LC Disbursement not later than 3:00 p.m.,
New York City time, on the date that such LC Disbursement is made if Borrower
shall have received notice of such LC Disbursement prior to 11:00 a.m., New York
City time, on such date, or, if such notice has not been received by Borrower
prior to such time on such date, then not later than 3:00 p.m., New York City
time, on the Business Day immediately following the day that Borrower receives
such notice; provided that Borrower may, subject to the conditions to borrowing
set forth herein, request in accordance with Section 2.03 that such payment be
financed with ABR Revolving Loans or Swingline Loans in an equivalent amount
and, to the extent so financed, Borrower's obligation to make such payment shall
be discharged and replaced by the resulting ABR Revolving Loans or Swingline
Loans.

          (ii) If Borrower fails to make such payment when due, the Issuing Bank
shall notify the Administrative Agent and the Administrative Agent shall notify
each Revolving Lender of the applicable LC Disbursement, the payment then due
from Borrower in respect thereof and such Revolving Lender's Pro Rata Percentage
thereof. Each Revolving Lender shall pay by wire transfer of immediately
available funds to the Administrative Agent not later than 2:00 p.m., New York
City time, on such date (or, if such Revolving Lender shall have received such
notice later than 12:00 noon, New York City time, on any day, not later than
11:00 a.m., New York City time, on the immediately following Business Day), an
amount equal to such Revolving Lender's Pro Rata Percentage of the unreimbursed
LC Disbursement in the same manner as provided in Section 2.02(c) with respect
to Revolving Loans made by such Revolving Lender, and the Administrative Agent
will promptly pay to the Issuing Bank the amounts so received by it from the
Revolving Lenders. The Administrative Agent will promptly pay to the Issuing
Bank any amounts received by it from Borrower pursuant to the above paragraph
prior to the time that any Revolving Lender makes any payment pursuant to the
preceding sentence and any such amounts received by the Administrative Agent
from Borrower thereafter will be promptly remitted by the Administrative Agent
to the Revolving Lenders that shall have made such payments and to the Issuing
Bank, as appropriate.

          (iii) If any Revolving Lender shall not have made its Pro Rata
Percentage of such LC Disbursement available to the Administrative Agent as
provided above, each of such Revolving Lender

                                      -59-

<PAGE>

and Borrower severally agrees to pay interest on such amount, for each day from
and including the date such amount is required to be paid in accordance with the
foregoing to but excluding the date such amount is paid, to the Administrative
Agent for the account of the Issuing Bank at (i) in the case of Borrower, the
rate per annum set forth in Section 2.18(h) and (ii) in the case of such Lender,
at a rate determined by the Administrative Agent in accordance with banking
industry rules or practices on interbank compensation.

          (f) Obligations Absolute. The Reimbursement Obligation of Borrower as
provided in Section 2.18(e) shall be absolute, unconditional and irrevocable,
and shall be paid and performed strictly in accordance with the terms of this
Agreement under any and all circumstances whatsoever and irrespective of (i) any
lack of validity or enforceability of any Letter of Credit or this Agreement, or
any term or provision therein; (ii) any draft or other document presented under
a Letter of Credit being proved to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; (iii) payment by the Issuing Bank under a Letter of Credit
against presentation of a draft or other document that fails to comply with the
terms of such Letter of Credit; (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the
provisions of this Section 2.18, constitute a legal or equitable discharge of,
or provide a right of setoff against, the obligations of Borrower hereunder; (v)
the fact that a Default shall have occurred and be continuing; or (vi) any
material adverse change in the business, property, results of operations,
prospects or condition, financial or otherwise, of Borrower and its
Subsidiaries. None of the Agents, the Lenders, the Issuing Bank or any of their
Affiliates shall have any liability or responsibility by reason of or in
connection with the issuance or transfer of any Letter of Credit or any payment
or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank; provided that the foregoing shall not be construed to excuse the
Issuing Bank from liability to Borrower to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are hereby waived
by Borrower to the extent permitted by applicable Requirements of Law) suffered
by Borrower that are caused by the Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto expressly agree that,
in the absence of gross negligence or willful misconduct on the part of the
Issuing Bank (as finally determined by a court of competent jurisdiction), the
Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Issuing Bank may, in its sole discretion, either accept and make payment upon
such documents without responsibility for further investigation, regardless of
any notice or information to the contrary, or refuse to accept and make payment
upon such documents if such documents are not in strict compliance with the
terms of such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit. The Issuing Bank shall promptly
give written notice to the Administrative Agent and Borrower of such demand for
payment and whether the Issuing Bank has made or will make an LC Disbursement
thereunder; provided that any failure to give or delay in giving such notice
shall not relieve Borrower of its Reimbursement Obligation to the Issuing Bank
and the Revolving Lenders with respect to any such LC Disbursement (other than
with respect to the timing of such Reimbursement Obligation set forth in Section
2.18(e)).

                                      -60-

<PAGE>

          (h) Interim Interest. If the Issuing Bank shall make any LC
Disbursement, then, unless Borrower shall reimburse such LC Disbursement in full
on the date such LC Disbursement is made, the unpaid amount thereof shall bear
interest payable on demand, for each day from and including the date such LC
Disbursement is made to but excluding the date that Borrower reimburses such LC
Disbursement, at the rate per annum determined pursuant to Section 2.06(c).
Interest accrued pursuant to this paragraph shall be for the account of the
Issuing Bank, except that interest accrued on and after the date of payment by
any Revolving Lender pursuant to Section 2.18(e) to reimburse the Issuing Bank
shall be for the account of such Lender to the extent of such payment.

          (i) Cash Collateralization. If any Event of Default shall occur and be
continuing, on the Business Day that Borrower receives notice from the
Administrative Agent or the Required Revolving Lenders (or, if the maturity of
the Loans has been accelerated, Revolving Lenders with LC Exposure representing
greater than 50% of the total LC Exposure) demanding the deposit of cash
collateral pursuant to this paragraph, Borrower shall deposit on terms and in
accounts satisfactory to the Collateral Agent, in the name of the Collateral
Agent and for the benefit of the Revolving Lenders, an amount in cash or Cash
Equivalents equal to the LC Exposure as of such date plus any accrued and unpaid
interest thereon; provided that the obligation to deposit such cash collateral
shall become effective immediately, and such deposit shall become immediately
due and payable, without demand or other notice of any kind, upon the occurrence
of any Event of Default with respect to Borrower described in Section 8.01(g) or
(h). Funds so deposited shall be applied by the Collateral Agent to reimburse
the Issuing Bank for LC Disbursements for which it has not been reimbursed and,
to the extent not so applied, shall be held for the satisfaction of outstanding
Reimbursement Obligations or, if the maturity of the Loans has been accelerated
(but subject to the consent of Revolving Lenders with LC Exposure representing
greater than 50% of the total LC Exposure), be applied to satisfy other
Obligations of Borrower under this Agreement. If Borrower is required to provide
an amount of cash collateral hereunder as a result of the occurrence of an Event
of Default, such amount plus any accrued interest or realized profits with
respect to such amounts (to the extent not applied as aforesaid) shall be
returned to Borrower within three Business Days after all Events of Default have
been cured or waived.

          (j) Additional Issuing Banks. Borrower may, at any time and from time
to time, designate one or more additional Revolving Lenders to act as an issuing
bank under the terms of this Agreement, with the consent of the Administrative
Agent (which consent shall not be unreasonably withheld) and such Revolving
Lender(s). Any Lender designated as an issuing bank pursuant to this paragraph
(j) shall be deemed (in addition to being a Revolving Lender) to be the Issuing
Bank with respect to Letters of Credit issued or to be issued by such Revolving
Lender, and all references herein and in the other Loan Documents to the term
"Issuing Bank" shall, with respect to such Letters of Credit, be deemed to refer
to such Revolving Lender in its capacity as Issuing Bank, as the context shall
require.

          (k) Resignation or Removal of the Issuing Bank. The Issuing Bank may
resign as Issuing Bank hereunder at any time upon at least 30 days' prior notice
to the Lenders, the Administrative Agent and Borrower. The Issuing Bank may be
replaced at any time by written agreement among Borrower, each Agent, the
replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent
shall notify the Lenders of any such replacement of the Issuing Bank or any such
additional Issuing Bank. At the time any such resignation or replacement shall
become effective, Borrower shall pay all unpaid fees accrued for the account of
the replaced Issuing Bank pursuant to Section 2.05(c). From and after the
effective date of any such resignation or replacement or addition, as
applicable, (i) the successor or additional Issuing Bank shall have all the
rights and obligations of the Issuing Bank under this Agreement with respect to
Letters of Credit to be issued by it thereafter and (ii) references herein to
the term "Issuing Bank" shall be deemed to refer to such successor or such
addition or to any previous Issuing Bank, or to

                                      -61-

<PAGE>

such successor or such addition and all previous Issuing Banks, as the context
shall require. After the resignation or replacement of an Issuing Bank
hereunder, the replaced Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of an Issuing Bank under this
Agreement with respect to Letters of Credit issued by it prior to such
resignation or replacement, but shall not be required to issue additional
Letters of Credit. If at any time there is more than one Issuing Bank hereunder,
Borrower may, in its discretion, select which Issuing Bank is to issue any
particular Letter of Credit.

          (l) Other. The Issuing Bank shall be under no obligation to issue any
Letter of Credit if

          (i) any order, judgment or decree of any Governmental Authority or
     arbitrator shall by its terms purport to enjoin or restrain the Issuing
     Bank from issuing such Letter of Credit, or any Requirement of Law
     applicable to the Issuing Bank or any request or directive (whether or not
     having the force of law) from any Governmental Authority with jurisdiction
     over the Issuing Bank shall prohibit, or request that the Issuing Bank
     refrain from, the issuance of letters of credit generally or such Letter of
     Credit in particular or shall impose upon the Issuing Bank with respect to
     such Letter of Credit any restriction, reserve or capital requirement (for
     which the Issuing Bank is not otherwise compensated hereunder) not in
     effect on the Amendment Effectiveness Date, or shall impose upon the
     Issuing Bank any unreimbursed loss, cost or expense which was not
     applicable on the Amendment Effectiveness Date and which the Issuing Bank
     in good faith deems material to it; or

          (ii) the issuance of such Letter of Credit would violate one or more
     policies of the Issuing Bank.

The Issuing Bank shall be under no obligation to amend any Letter of Credit if
(A) the Issuing Bank would have no obligation at such time to issue such Letter
of Credit in its amended form under the terms hereof, or (B) the beneficiary of
such Letter of Credit does not accept the proposed amendment to such Letter of
Credit.

          SECTION 2.19 INCREASE IN COMMITMENTS.

          (a) Borrower Request. After a Successful Syndication is completed,
Borrower may by 10 Business Days' written notice to the Administrative Agent
request, on up to but no more than four separate occasions, the establishment of
one or more new Term Loan Commitments (it being understood that this is in
addition to the New Term Loan Commitments) by an amount not in excess of $40.0
million in the aggregate and not less than $5.0 million individually. Each such
notice shall specify (i) the date (each, an "INCREASE EFFECTIVE DATE") on which
Borrower proposes that the increased or new Commitments shall be effective,
which shall be a date not less than 10 Business Days after the date on which
such notice is delivered to the Administrative Agent and (ii) the identity of
each Eligible Assignee to whom Borrower proposes any portion of such increased
or new Commitments be allocated and the amounts of such allocations; provided
that any existing Lender approached to provide all or a portion of the increased
or new Commitments may elect or decline, in its sole discretion, to provide such
increased or new Commitment.

          (b) Conditions. The increased or new Commitments shall become
effective, as of such Increase Effective Date; provided that:

          (i) each of the conditions set forth in Section 4.02 shall be
     satisfied;

                                      -62-

<PAGE>

          (ii) no Event of Default shall have occurred and be continuing or
     would result from the borrowings to be made on the Increase Effective Date;

          (iii) as of the Test Period, after calculating Consolidated EBITDA,
     Indebtedness and Consolidated Interest Expense on a Pro Forma Basis to give
     effect to the borrowings to be made on the Increase Effective Date, the
     Acquisition, the Projects, any Permitted Acquisition (including any
     Permitted Acquisition financed on the Increase Effective Date) and Asset
     Sales consummated at any time on or after the first day of the Test Period
     as if the Acquisition, the Projects and each such Permitted Acquisition had
     been effected on the first day of such period and as if each such Asset
     Sale had been consummated on the first day of such period, Borrower shall
     be in compliance with each of the covenants set forth in Section 6.10;

          (iv) Borrower shall deliver or cause to be delivered any legal
     opinions or other documents reasonably requested by the Administrative
     Agent in connection with any such transaction.

          (c) Terms of New Loans and Commitments. The terms and provisions of
Loans made pursuant to the new Commitments shall be as follows:

          (i) terms and provisions of Term Loans made pursuant to new
     Commitments shall be, except as otherwise set forth herein or in the
     Increase Joinder, identical to the Term Loans (it being understood that
     such Term Loans may be part of an existing tranche of Term Loans);

          (ii) the weighted average life to maturity of all new Term Loans shall
     be no shorter than the weighted average life to maturity of the existing
     Term Loans;

          (iii) the maturity date of the new Term Loans shall not be earlier
     than the Final Maturity Date;

          (iv) the Applicable Margins for the new Term Loans shall be determined
     by Borrower and the applicable new Lenders; provided, however, that the
     Applicable Margins for the new Term Loans shall not be greater than the
     Applicable Margins then payable with respect to the Term Loans plus 50
     basis points.

The increased or new Commitments shall be effected by a joinder agreement (the
"INCREASE JOINDER") executed by Borrower, the Administrative Agent and each
Lender making such increased or new Commitment, in form and substance
satisfactory to each of them. The Increase Joinder may, without the consent of
any other Lenders, effect such amendments to this Agreement and the other Loan
Documents as may be necessary or appropriate, in the opinion of the
Administrative Agent, to effect the provisions of this Section 2.19.

          (d) Making of New Term Loans. On any Increase Effective Date on which
new Commitments for Term Loans are effective, subject to the satisfaction of the
foregoing terms and conditions, each Lender of such new Commitment shall make a
Term Loan to Borrower in an amount equal to its new Commitment.

          (e) Equal and Ratable Benefit. The Loans and Commitments established
pursuant to this paragraph shall constitute Loans and Commitments under, and
shall be entitled to all the benefits afforded by, this Agreement and the other
Loan Documents, and shall, without limiting the foregoing, benefit equally and
ratably from the Guarantees and security interests created by the Security
Documents. The Loan Parties shall take any actions reasonably required by the
Administrative Agent to ensure and/or

                                      -63-

<PAGE>

demonstrate that the Lien and security interests granted by the Security
Documents continue to be perfected under the UCC or otherwise after giving
effect to the establishment of any such Class of Term Loans or any such new
Commitments.

          SECTION 2.20 MODIFICATION OF REVOLVING LOAN.

          (a) Borrower Request. Borrower may by 30 Business Days' written notice
to the Administrative Agent elect to request, effective as of the Revolving
Maturity Date, to extend the Revolving Loans and the Revolving Loan Commitments
beyond the Revolving Maturity Date or to replace the Revolving Loan Commitments.
Such notice shall specify (i) the date on which the Borrower proposes that the
extended or new Revolving Loan Commitments shall mature and (ii) the identity of
each Eligible Assignee to whom Borrower proposes any portion of such extended or
new Revolving Loan Commitments be allocated and the amounts of such allocations;
provided that any existing Lender approached to provide all or a portion of the
extended or new Revolving Loan Commitments may elect or decline, in its sole
discretion, to provide such extended or new Revolving Loan Commitment and if it
so declines the unpaid principal amount of its Revolving Loans shall be paid in
full on the Revolving Maturity Date.

          (b) Conditions. The extended or new Revolving Loan Commitments shall
become effective, as of the Revolving Loan Maturity Date; provided that:

          (i) each of the conditions set forth in Section 4.02 shall be
     satisfied;

          (ii) no Event of Default shall have occurred and be continuing or
     would result from the extension or replacement of the Revolving Loan
     Commitments; and

          (iii) Borrower shall deliver or cause to be delivered any legal
     opinions or other documents reasonably requested by the Administrative
     Agent in connection with any such transaction.

          (c) Terms of New Revolving Loans and Revolving Loan Commitments. The
terms and provisions of Revolving Loans and Revolving Loan Commitments made
pursuant to such extension or replacement shall be identical to those of the
current Revolving Loans and Revolving Loan Commitments. The extended or new
Revolving Loan Commitments shall be effected by a joinder agreement (the
"REVOLVING LOAN JOINDER") executed by Borrower, the Administrative Agent and
each Lender making such extended or new Commitment, in form and substance
satisfactory to each of them. The Revolving Loan Joinder may, without the
consent of any other Lenders, effect such amendments to this Agreement and the
other Loan Documents as may be necessary or appropriate, in the opinion of the
Administrative Agent, to effect the provisions of this Section 2.20.

          (d) Equal and Ratable Benefit. The Loans and Commitments extended or
established pursuant to this paragraph shall constitute Loans and Commitments
under, and shall be entitled to all the benefits afforded by, this Agreement and
the other Loan Documents, and shall, without limiting the foregoing, benefit
equally and ratably from the Guarantees and security interests created by the
Security Documents. The Loan Parties shall take any actions reasonably required
by the Administrative Agent to ensure and/or demonstrate that the Lien and
security interests granted by the Security Documents continue to be perfected
under the UCC or otherwise after giving effect to the extension or establishment
of any such Loans or any such Commitments.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

          Each Loan Party represents and warrants to the Administrative Agent,
the Collateral Agent, the Issuing Bank and each of the Lenders (with references
to the Companies being references thereto after giving effect to the
Transactions, the Amendment Transactions and the Second Amendment Transactions
to occur on the Amendment Effectiveness Date unless otherwise expressly stated)
that:

          SECTION 3.01 ORGANIZATION; POWERS. Each Company (a) is duly organized
and validly existing under the laws of the jurisdiction of its organization, (b)
has all requisite organizational power and authority to carry on its business as
now conducted and to own and lease its property and (c) is qualified and in good
standing (to the extent such concept is applicable in the applicable
jurisdiction) to do business in every jurisdiction where such qualification is
required, except in such jurisdictions where the failure to so qualify or be in
good standing, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. There is no existing default
under any Organizational Document of any Company or any event which, with the
giving of notice or passage of time or both, would constitute a default by any
party thereunder.

          SECTION 3.02 AUTHORIZATION; ENFORCEABILITY. The Second Amendment
Transactions to be entered into by each Loan Party are within such Loan Party's
powers and have been duly authorized by all necessary action on the part of such
Loan Party. This Agreement has been duly executed and delivered by each Loan
Party and constitutes, and each other Loan Document to which any Loan Party is
to be a party, when executed and delivered by such Loan Party, will constitute,
a legal, valid and binding obligation of such Loan Party, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally
and subject to general principles of equity, regardless of whether considered in
a proceeding in equity or at law.

          SECTION 3.03 NO CONFLICTS. Except as set forth on Schedule 3.03, the
Second Amendment Transactions (a) do not require any consent or approval of,
registration or filing with, or any other action by, any Governmental Authority,
except (i) such as have been obtained or made and are in full force and effect,
(ii) filings necessary to perfect Liens created by the Loan Documents and the
Second Lien Loan Documents and (iii) consents, approvals, registrations,
filings, permits or actions the failure to obtain or perform which could not
reasonably be expected to result in a Material Adverse Effect, (b) will not
violate the Organizational Documents of any Company, (c) will not violate any
Requirement of Law in any material respect, (d) will not violate or result in a
default or require any consent or approval under any indenture, agreement or
other instrument binding upon any Company or its property, or give rise to a
right thereunder to require any payment to be made by any Company, except for
violations, defaults or the creation of such rights that could not reasonably be
expected to result in a Material Adverse Effect, and (e) will not result in the
creation or imposition of any Lien on any property of any Company, except Liens
created by the Loan Documents and Permitted Liens.

          SECTION 3.04 FINANCIAL STATEMENTS; PROJECTIONS.

          (a) Historical Financial Statements. Borrower has heretofore delivered
to the Lenders the consolidated balance sheets and related income statements and
statements of cash flows and statements of changes in member interests of
Borrower (x)(i) as of, and for the period from April 2, 2003 through, December
31, 2003, and (ii) as of and for the fiscal year ended December 31, 2004, in
each case

                                      -65-

three-month and six-month periods ended June 30, 2005 and as of and for the
three-month and six-month periods ended June 30, 2004, in the case of clauses
(x) and (y), certified by the chief financial officer of Borrower. Such
financial statements and all financial statements delivered pursuant to Sections
5.01(a) and (b) have been prepared in accordance with GAAP and fairly present,
in all material respects, the consolidated financial condition and results of
operations and cash flows of Borrower and its Subsidiaries as of the dates and
for the periods to which they relate.

          (b) No Liabilities. Except as set forth in the financial statements
referred to in Section 3.04(a), there are no liabilities of any Company of any
kind, whether accrued, contingent, absolute, determined, determinable or
otherwise, which could reasonably be expected to result in a Material Adverse
Effect, and there is no existing condition, situation or set of circumstances
which could reasonably be expected to result in such a liability, other than
liabilities permitted under the Loan Documents and the Second Lien Loan
Documents. Since December 31, 2003 there has been no event, change, circumstance
or occurrence that, individually or in the aggregate, has had or could
reasonably be expected to result in a Material Adverse Effect.

          (c) Pro Forma Financial Statements. Holdings has heretofore delivered
to the Lenders Borrower's unaudited pro forma consolidated balance sheet and
statement of income, pro forma EBITDA and other operating data for the fiscal
year ended December 31, 2003, and as of and for the nine-month period ended
September 30, 2004, in each case after giving effect to the Transactions as if
they had occurred on such date in the case of the balance sheet and as of the
beginning of all periods presented in the case of the statement of income. Such
pro forma financial statements have been prepared in good faith by Holdings,
based on the assumptions stated therein (which assumptions are believed by
Holdings on the date hereof and on the Closing Date to be reasonable in light of
current conditions and facts then known to Holdings), are based on the best
information available to Holdings as of the date of delivery thereof, accurately
reflect all adjustments required to be made to give effect to the Transactions,
and present fairly in all material respects the pro forma consolidated financial
position and results of operations of Borrower and its Subsidiaries as of such
date and for such periods, assuming that the Transactions had occurred at such
dates.

          (d) Forecasts. The forecasts of financial performance of Borrower and
its subsidiaries furnished to the Lenders have been prepared in good faith by
Holdings and based on assumptions believed by Borrower to be reasonable at the
time such forecasts were provided (and on the Closing Date in the case of
forecasts provided prior to the Closing Date) (it being recognized by the
Lenders, however, that projections as to future events are not to be viewed as
facts and that actual results during the period(s) covered by such projections
may differ from the projected results and that such differences may be material
and that the Loan Parties make no representation that such projections will be
realized).

          SECTION 3.05 PROPERTIES.

          (a) Generally. Each Company has good title to, or valid leasehold
interests in, all its property material to its business, free and clear of all
Liens except for, in the case of Collateral, Permitted Collateral Liens and, in
the case of all other material property, Permitted Liens and minor
irregularities or deficiencies in title that, individually or in the aggregate,
do not materially interfere with its ability to conduct its business as
currently conducted or to utilize such property for its intended purpose. The
property

                                      -66-

<PAGE>

of the Companies, taken as a whole, (i) is in good operating order, condition
and repair (ordinary wear and tear excepted) in accordance with industry
standards and (ii) constitutes all the property which is required for the
business and operations of the Companies as presently conducted.

          (b) Real Property. Schedules 8(a) and 8(b) to the Perfection
Certificate dated the Amendment Effectiveness Date contain a true and complete
list of each interest in Real Property (i) owned by any Company as of the date
hereof and describes the type of interest therein held by such Company and
whether such owned Real Property is leased and if leased whether the underlying
Lease contains any option to purchase all or any portion of such Real Property
or any interest therein or contains any right of first refusal relating to any
sale of such Real Property or any portion thereof or interest therein and (ii)
leased, subleased or otherwise occupied or utilized by any Company, as lessee,
sublessee, franchisee or licensee, as of the date hereof and describes the type
of interest therein held by such Company and, in each of the cases described in
clauses (i) and (ii) of this Section 3.05(b), whether any Lease requires the
consent of the landlord or tenant thereunder, or other party thereto, to the
Second Amendment Transactions. As of the Amendment Effectiveness Date, with
respect to each Real Property or Mortgaged Property, there are no Leases in
which Borrower or any Subsidiary holds the lessor's interest.

          (c) No Casualty Event. No Company has received any notice of, nor has
any knowledge of, the occurrence or pendency or contemplation of any Casualty
Event affecting all or any material portion of its property. No Mortgage
encumbers improved Real Property that is located in an area that as of the date
of this Agreement has been identified by the Secretary of Housing and Urban
Development as an area having special flood hazards within the meaning of the
National Flood Insurance Act of 1968 unless flood insurance available under such
Act has been obtained in accordance with Section 5.04.

          (d) Collateral. Each Company owns or has rights to use all of the
Collateral and all rights with respect to any of the foregoing used in,
necessary for or material to each Company's business as currently conducted. The
use by each Company of such Collateral and all such rights with respect to the
foregoing do not infringe on the rights of any person other than such
infringement which could not, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Effect. No claim has been made and
remains outstanding that any Company's use of any Collateral does or may violate
the rights of any third party that could, individually or in the aggregate,
reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.06 INTELLECTUAL PROPERTY.

          (a) Ownership/No Claims. Each Loan Party owns, or is licensed to use,
all patents, patent applications, trademarks, trade names, servicemarks,
copyrights, technology, trade secrets, proprietary information, domain names,
know-how and processes necessary for the conduct of its business as currently
conducted (the "INTELLECTUAL PROPERTY"), except for those the failure to own or
license which, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No claim has been asserted and
is pending by any person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property, nor does any Loan Party know of any valid basis for any such claim, in
each case that could reasonably be expected to result in a Material Adverse
Effect. The use of such Intellectual Property by each Loan Party does not
infringe the rights of any person, except for such claims and infringements
that, individually or in the aggregate, could not reasonably be expected to
result in a Material Adverse Effect.

          (b) Registrations. Except pursuant to licenses and other user
agreements entered into by each Loan Party in the ordinary course of business
that are listed in Schedule 12(a) or 12(b) to the Perfection

                                      -67-

<PAGE>

Certificate, on and as of the date hereof (i) each Loan Party owns and possesses
the right to use, and has done nothing to authorize or enable any other person
to use, any copyright, patent or trademark (as such terms are defined in the
Security Agreement) listed in Schedule 12(a) or 12(b) to the Perfection
Certificate and (ii) all registrations listed in Schedule 12(a) or 12(b) to the
Perfection Certificate are valid and in full force and effect.

          (c) No Violations or Proceedings. To each Loan Party's knowledge, on
and as of the date hereof, there is no material violation by others of any right
of such Loan Party with respect to any copyright, patent or trademark listed in
Schedule 12(a) or 12(b) to the Perfection Certificate, pledged by it under the
name of such Loan Party except as may be set forth on Schedule 3.06(c).

          SECTION 3.07 EQUITY INTERESTS AND SUBSIDIARIES.

          (a) Equity Interests. Schedules 1(a) and 10(a) to the Perfection
Certificate dated the Amendment Effectiveness Date set forth a list of (i) all
the Subsidiaries of Holdings and their jurisdictions of organization as of the
Amendment Effectiveness Date and (ii) the number of each class of its Equity
Interests authorized, and the number outstanding, on the Amendment Effectiveness
Date and the number of shares covered by all outstanding options, warrants,
rights of conversion or purchase and similar rights at the Amendment
Effectiveness Date. All Equity Interests of each Company are duly and validly
issued and are fully paid and non-assessable, and, other than the Equity
Interests of Borrower and Holdings, are owned by Borrower, directly or
indirectly through Wholly Owned Subsidiaries. All Equity Interests of Borrower
are owned directly by Holdings. Each Loan Party is the record and beneficial
owner of, and has good and defensible title to, the Equity Interests pledged by
it under the Security Agreement, free of any and all Liens, rights or claims of
other persons, except the security interest created by the Security Agreement
and the Second Lien Loan Documents, and there are no outstanding warrants,
options or other rights to purchase, or shareholder, voting trust or similar
agreements outstanding with respect to, or property that is convertible into, or
that requires the issuance or sale of, any such Equity Interests. All
Subsidiaries of Holdings, other than Borrower, existing on the Amendment
Effectiveness Date are Guarantors.

          (b) No Consent of Third Parties Required. No consent of any person
including any other general or limited partner, any other member of a limited
liability company, any other shareholder or any other trust beneficiary is
necessary or reasonably desirable (from the perspective of a secured party) in
connection with the creation, perfection or First Priority status of the
security interest of the Collateral Agent in any Equity Interests pledged to the
Collateral Agent for the benefit of the Secured Parties under the Security
Agreement or the exercise by the Collateral Agent of the voting or other rights
provided for in the Security Agreement or the exercise of remedies in respect
thereof.

          (c) Organizational Chart. An accurate organizational chart, showing
the ownership structure of Holdings, Borrower and each Subsidiary on the
Amendment Effectiveness Date, and after giving effect to the Transactions, the
Amendment Transactions and the Second Amendment Transactions, is set forth on
Schedule 10(a) to the Perfection Certificate dated the Amendment Effectiveness
Date.

          SECTION 3.08 LITIGATION; COMPLIANCE WITH LAWS. There are no actions,
suits or proceedings at law or in equity by or before any Governmental Authority
now pending or, to the knowledge of any Company, threatened against or affecting
any Company or any business, property or rights of any Company (i) that involve
any Loan Document or any of the Transactions, the Amendment Transactions or the
Second Amendment Transactions or (ii) which could reasonably be expected,
individually or in the aggregate, to result in a Material Adverse Effect. Except
for matters covered by Section 3.18, no

                                      -68-

<PAGE>

Company or any of its property is in violation of, nor will the continued
operation of its property as currently conducted violate, any Requirements of
Law (including any zoning or building ordinance, code or approval or any
building permits) or any restrictions of record or agreements affecting any
Company's Real Property or is in default with respect to any Requirement of Law,
where such violation or default, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.09 AGREEMENTS. No Company is a party to any agreement or
instrument or subject to any corporate or other constitutional restriction that
has resulted or could reasonably be expected to result in a Material Adverse
Effect. No Company is in default in any manner under any provision of any
indenture or other agreement or instrument evidencing Indebtedness, or any other
agreement or instrument to which it is a party or by which it or any of its
property is or may be bound, where such default could reasonably be expected to
result in a Material Adverse Effect, and no condition exists which, with the
giving of notice or the lapse of time or both, would constitute such a default.
Schedule 3.09 accurately and completely lists all material agreements (other
than leases of Real Property set forth on Schedule 8(a) or 8(b) to the
Perfection Certificate dated the Amendment Effectiveness Date) to which any
Company is a party which are in effect on the date hereof in connection with the
operation of the business conducted thereby and Borrower has delivered to the
Administrative Agent complete and correct copies of all such material
agreements, including any amendments, supplements or modifications with respect
thereto, and all such agreements are in full force and effect.

          SECTION 3.10 FEDERAL RESERVE REGULATIONS. No Company is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of buying or carrying Margin Stock. No part of the
proceeds of any Loan or any Letter of Credit will be used, whether directly or
indirectly, and whether immediately, incidentally or ultimately, for any purpose
that entails a violation of, or that is inconsistent with, the provisions of the
regulations of the Board, including Regulation T, U or X. The pledge of the
Securities Collateral pursuant to the Security Agreement does not violate such
regulations.

          SECTION 3.11 INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY
ACT. No Company is (a) an "investment company" or a company "controlled" by an
"investment company," as defined in, or subject to regulation under, the
Investment Company Act of 1940, as amended, or (b) a "holding company," an
"affiliate" of a "holding company" or a "subsidiary company" of a "holding
company," as defined in, or subject to regulation under, the Public Utility
Holding Company Act of 1935, as amended, other than in compliance with Section
9(a)(2) thereof. No approval, consent or notice pursuant to the Public Utility
Holding Company Act of 1935, as amended, is required in connection with the
Transactions, the Amendment Transactions or the Second Amendment Transactions or
is required in connection with making any extensions of credit hereunder.

          SECTION 3.12 USE OF PROCEEDS. Borrower will use the proceeds of (a)
the Term Loans and the Revolving Loans funded on the Closing Date (together with
the proceeds of the Second Lien Loans) to finance the Transactions (other than
the Regency Equity Financing) and pay related fees, commissions and expenses,
(b) the Additional Term Loans to fund the Projects, (c) the New Term Loans to
repay the Revolving Loans and the Second Lien Loans, (d) the Term Loans funded
after the Amendment Effectiveness Date (other than the New Term Loans) in
accordance with Section 2.19, and (e) the Revolving Loans funded after the
Closing Date, and the Swingline Loans, after the Closing Date for working
capital and general corporate purposes (including to effect Permitted
Acquisitions and the Projects).

<PAGE>

          SECTION 3.13 TAXES. Each Company has (a) timely filed or caused to be
timely filed all federal Tax Returns and all material state, local and foreign
Tax Returns or materials required to have been filed by it and (b) duly and
timely paid, collected or remitted or caused to be duly and timely paid,
collected or remitted all Taxes (whether or not shown on any Tax Return) due and
payable, collectible or remittable by it and all assessments received by it,
except Taxes (i) that are being contested in good faith by appropriate
proceedings and for which such Company has set aside on its books adequate
reserves in accordance with GAAP and (ii) which could not, individually or in
the aggregate, have a Material Adverse Effect. Each Company has made adequate
provision in accordance with GAAP for all Taxes not yet due and payable. Each
Company is unaware of any proposed or pending tax assessments, deficiencies or
audits that could be reasonably expected to, individually or in the aggregate,
result in a Material Adverse Effect. No Company has ever been a party to any
understanding or arrangement constituting a "tax shelter" within the meaning of
Section 6111(c), Section 6111(d) or Section 6662(d)(2)(C)(iii) of the Code, or
has ever "participated" in a "reportable transaction" within the meaning of
Treasury Regulation Section 1.6011-4, except as could not be reasonably expected
to, individually or in the aggregate, result in a Material Adverse Effect.

          SECTION 3.14 NO MATERIAL MISSTATEMENTS. No written information,
report, financial statement, certificate, Borrowing Request, LC Request, exhibit
or schedule furnished by or on behalf of any Company to the Administrative Agent
or any Lender in connection with the negotiation of any Loan Document or
included therein or delivered pursuant thereto, taken as a whole, or the
Original Confidential Information Memorandum or the Amendment Confidential
Information Memorandum or the New Confidential Information Memorandum contained
or contains any material misstatement of fact or omitted or omits to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were or are made, not misleading as of the date
such information is dated or certified; provided that (i) to the extent any such
information, report, financial statement, exhibit or schedule was based upon or
constitutes a forecast or projection, each Company represents only that it acted
in good faith and utilized reasonable assumptions and due care in the
preparation of such information, report, financial statement, exhibit or
schedule (it being recognized by the Lenders, however, that projections as to
future events are not to be viewed as facts and that results during the
period(s) covered by such projections may differ from the projected results and
that such differences may be material and that the Loan Parties make no
representation that such projections will be realized) and (ii) as to
statements, information and reports supplied by third parties after the
Amendment Effectiveness Date, Borrower represents only that it is not aware of
any material misstatement or omission therein.

          SECTION 3.15 LABOR MATTERS. As of the date hereof and the Amendment
Effectiveness Date, there are no strikes, lockouts or slowdowns against any
Company pending or, to the knowledge of any Company, threatened. The hours
worked by and payments made to employees of any Company have not been in
violation of the Fair Labor Standards Act of 1938, as amended, or any other
applicable federal, state, local or foreign law dealing with such matters in any
manner which could reasonably be expected to result in a Material Adverse
Effect. All payments due from any Company, or for which any claim may be made
against any Company, on account of wages and employee health and welfare
insurance and other benefits, have been paid or accrued as a liability on the
books of such Company except where the failure to do so could not reasonably be
expected to result in a Material Adverse Effect. The consummation of the
Transactions, the Amendment Transactions and the Second Amendment Transactions
will not give rise to any right of termination or right of renegotiation on the
part of any union under any collective bargaining agreement to which any Company
is bound.

          SECTION 3.16 SOLVENCY. Immediately after the consummation of the
Second Amendment Transactions to occur on the Amendment Effectiveness Date and
immediately following the

                                      -70-

<PAGE>

making of each Loan and after giving effect to the application of the proceeds
of each Loan, (a) the fair value of the properties of each Loan Party
(individually and on a consolidated basis with its Subsidiaries, and determined
on a going concern basis) will exceed the probable liability of its debts and
other liabilities, subordinated, contingent or otherwise; (b) the present fair
saleable value of the property of each Loan Party (individually and on a
consolidated basis with its Subsidiaries) will be greater than the amount that
will be required to pay the probable liability of its debts and other
liabilities, subordinated, contingent or otherwise, as such debts and other
liabilities become absolute and matured; (c) each Loan Party (individually and
on a consolidated basis with its Subsidiaries) will be able to pay its debts and
liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; and (d) each Loan Party (individually
and on a consolidated basis with its Subsidiaries) will not have unreasonably
small capital with which to conduct its business in which it is engaged as such
business is now conducted and is proposed to be conducted following the
Amendment Effectiveness Date.

          SECTION 3.17 EMPLOYEE BENEFIT PLANS. Each Company and its ERISA
Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events,
could reasonably be expected to result in material liability of any Company or
any of its ERISA Affiliates or the imposition of a Lien on any of the property
of any Company. The present value of all accumulated benefit obligations of all
underfunded Plans (based on the assumptions used for purposes of Statement of
Financial Accounting Standards No. 87) did not, as of the date of the most
recent financial statements reflecting such amounts, exceed by more than
$250,000 the fair market value of the property of all such underfunded Plans.
Using actuarial assumptions and computation methods consistent with subpart I of
subtitle E of Title IV of ERISA, the aggregate liabilities of each Company or
its ERISA Affiliates to all Multiemployer Plans in the event of a complete
withdrawal therefrom, as of the close of the most recent fiscal year of each
such Multiemployer Plan, could not reasonably be expected to result in a
Material Adverse Effect.

          SECTION 3.18 ENVIRONMENTAL MATTERS.

          (a) Except as set forth in Schedule 3.18 and except as, individually
or in the aggregate, could not reasonably be expected to result in a Material
Adverse Effect:

          (i) The Companies and their businesses, operations and Real Property
     are in compliance with, and the Companies have no liability under,

     for the conduct of their businesses and operations, and the ownership,
     operation and use of their property, under Environmental Law, all such
     Environmental Permits are valid and in good standing and, under the
     currently effective business plan of the Companies, no expenditures or
     operational adjustments will be required in order to renew or modify such
     Environmental Permits during the next five years;

          (iii) There has been no Release or threatened Release of Hazardous
     Material on, at, under or from any Real Property or facility presently or
     formerly owned, leased or operated by the Companies or their predecessors
     in interest that could result in liability by the Companies under
     Environmental Law;

          (iv) There is no Environmental Claim pending or, to the knowledge of
     the Companies, threatened against the Companies, or relating to the Real
     Property currently or formerly

                                      -71-

<PAGE>

     owned, leased or operated by the Companies or relating to the operations of
     the Companies, and there are no actions, activities, circumstances,
     conditions, events or incidents that could form the basis of such an
     Environmental Claim; and

          (v) No person with an indemnity or contribution obligation to the
     Companies relating to compliance with or liability under Environmental Law
     is in default with respect to such obligation.

          (b) Except as set forth in Schedule 3.18:

          (i) (A) On the Amendment Effectiveness Date, no Company is obligated
     to perform any action or otherwise incur any expense under Environmental
     Law pursuant to any order, decree, judgment or agreement by which it is
     bound or has assumed by contract or agreement, and no Company is conducting
     or financing any Response pursuant to any Environmental Law with respect to
     any Real Property or any other location and (B) after the Amendment
     Effectiveness Date, no Company is obligated to perform any action or
     otherwise incur any expense under Environmental Law pursuant to any order,
     decree, judgment or agreement by which it is bound or has assumed by
     contract or agreement, and no Company is conducting or financing any
     Response pursuant to any Environmental Law with respect to any Real
     Property or any other location, except, in each case, as individually or in
     the aggregate could not reasonably be expected to result in a Material
     Adverse Effect;

          (ii) No Real Property or facility owned, operated or leased by the
     Companies and, to the knowledge of the Companies, no Real Property or
     facility formerly owned, operated or leased by the Companies or any of
     their predecessors in interest is (i) listed or proposed for listing on the
     National Priorities List promulgated pursuant to CERCLA or (ii) listed on
     the Comprehensive Environmental Response, Compensation and Liability
     Information System promulgated pursuant to CERCLA or (iii) included on any
     similar list maintained by any Governmental Authority including any such
     list relating to petroleum;

          (iii) No material Lien has been recorded or, to the knowledge of any
     Company, threatened under any Environmental Law with respect to any Real
     Property or other assets of the Companies;

          (iv) The execution, delivery and performance of this Agreement and the
     consummation of the transactions contemplated hereby will not require any
     notification, registration, filing, reporting, disclosure, investigation,
     remediation or cleanup pursuant to any Governmental Real Property
     Disclosure Requirements or any other Environmental Law; and

          (v) The Companies have made available to the Lenders all material
     records and files in the possession, custody or control of, or otherwise
     reasonably available to, the Companies concerning compliance with or
     liability under Environmental Law, including those concerning the existence
     of Hazardous Material at Real Property or facilities currently or formerly
     owned, operated, leased or used by the Companies.

          SECTION 3.19 INSURANCE. Schedule 3.19 sets forth a true, complete and
correct description of all insurance maintained by each Company as of the
Amendment Effectiveness Date. All insurance maintained by the Companies is in
full force and effect, all premiums have been duly paid, no Company has received
notice of violation or cancellation thereof, the Premises, and the use,
occupancy

                                      -72-

<PAGE>

and operation thereof, comply in all material respects with all Insurance
Requirements, and there exists no default under any Insurance Requirement except
as could not reasonably be expected to cause or result in a Material Adverse
Effect. Each Company has insurance in such amounts and covering such risks and
liabilities as are customary for companies of a similar size engaged in similar
businesses in similar locations.

          SECTION 3.20 SECURITY DOCUMENTS.

          (a) Security Agreement. The Security Agreement is effective to create
in favor of the Collateral Agent for the benefit of the Secured Parties, legal,
valid and enforceable Liens on, and security interests in, the Security
Agreement Collateral and, (i) when financing statements and other filings in
appropriate form are filed in the offices specified on Schedule 7 to the
Perfection Certificate and (ii) upon the taking of possession or control by the
Collateral Agent of the Security Agreement Collateral with respect to which a
security interest may be perfected only by possession or control (which
possession or control shall be given to the Collateral Agent to the extent
possession or control by the Collateral Agent is required by each Security
Agreement), the Liens created by the Security Agreement shall constitute fully
perfected First Priority Liens on, and security interests in, all right, title
and interest of the grantors thereunder in the Security Agreement Collateral
(other than such Security Agreement Collateral in which a security interest
cannot be perfected under the UCC as in effect at the relevant time in the
relevant jurisdiction), in each case subject to no Liens other than Permitted
Collateral Liens.

          (b) Copyright Office Filing. When the Security Agreement or a short
form thereof is filed in the United States Copyright Office, the Liens created
by such Security Agreement shall constitute fully perfected First Priority Liens
on, and security interests in, all right, title and interest of the grantors
thereunder in the Registered Copyrights and Registered Copyright Licenses (each
as defined in such Security Agreement), in each case subject to no Liens other
than Permitted Collateral Liens.

          (c) Mortgages. Each Mortgage (as amended by the Mortgage Amendments,
if applicable) is effective to create, in favor of the Collateral Agent, for its
benefit and the benefit of the Secured Parties, legal, valid and enforceable
First Priority Liens on, and security interests in, all of the Loan Parties'
right, title and interest in and to the Mortgaged Properties thereunder and the
proceeds thereof, subject only to Permitted Collateral Liens or other Liens
acceptable to the Collateral Agent, and when the Mortgages are filed in the
offices specified on Schedule 8(a) to the Perfection Certificate dated the
Amendment Effectiveness Date (or, in the case of any Mortgage executed and
delivered after the date thereof in accordance with the provisions of Sections
5.11 and 5.12, when such Mortgage is filed in the offices specified in the local
counsel opinion delivered with respect thereto in accordance with the provisions
of Sections 5.11 and 5.12), the Mortgages shall constitute First Priority fully
perfected Liens on, and security interests in, all right, title and interest of
the Loan Parties in the Mortgaged Properties and the proceeds thereof, in each
case prior and superior in right to any other person, other than Liens permitted
by such Mortgage.

          (d) Valid Liens. Each Security Document delivered pursuant to Sections
5.11 and 5.12 will, upon execution and delivery thereof, be effective to create
in favor of the Collateral Agent, for the benefit of the Secured Parties, legal,
valid and enforceable Liens on, and security interests in, all of the Loan
Parties' right, title and interest in and to the Collateral thereunder, and when
all appropriate filings or recordings are made in the appropriate offices as may
be required under applicable law, such Security Document will constitute First
Priority fully perfected Liens on, and security interests in, all right, title
and interest of the Loan Parties in such Collateral, in each case subject to no
Liens other than the applicable Permitted Collateral Liens.

          SECTION 5.04 INSURANCE.

          (a) Generally. Keep its insurable property adequately insured at all
times by reputable insurers that are, to the knowledge of the Loan Parties,
financially sound; maintain such other insurance, to such extent and against
such risks as is customary with companies in the same or similar businesses
operating in the same or similar locations, including insurance with respect to
Mortgaged Properties and other properties material to the business of the
Companies against such casualties and contingencies and of such types and in
such amounts with such deductibles as is customary in the case of similar
businesses operating in the same or similar locations, including (i) physical
hazard insurance on an "all risk" basis, (ii) commercial general liability
against claims for bodily injury, death or property damage covering any and all
insurable claims as are usually carried by companies of established repute
engaged in the same or similar business owning similar properties and located in
the same general areas, (iii) explosion insurance in respect of any boilers,
machinery or similar apparatus constituting Collateral, (iv) business
interruption insurance, (v) worker's compensation insurance and such other
insurance as may be required by any Requirement of Law and (vi) such other
insurance against risks as the Administrative Agent may from time to time
require (such policies to be in such form and amounts and having such coverage
as may be reasonably satisfactory to the Administrative Agent and the Collateral
Agent); provided that with respect to physical hazard insurance, neither the
Collateral Agent nor the applicable Company shall agree to the adjustment of any
claim thereunder without the consent of the other (such consent not to be
unreasonably withheld or delayed); provided, further, that no consent of any
Company shall be required during the continuance of an Event of Default.

          (b) Requirements of Insurance. All such insurance shall (i) provide
that no cancellation, material reduction in amount or material change in
coverage thereof shall be effective until at least 30 days after receipt by the
Collateral Agent of written notice thereof, (ii) name the Collateral Agent as
mortgagee (in the case of property insurance) or additional insured on behalf of
the Secured Parties (in the case of liability insurance) or loss payee (in the
case of property insurance), as applicable, and (iii) be reasonably satisfactory
in all other respects to the Collateral Agent.

          (c) Notice to Agents. Notify the Administrative Agent and the
Collateral Agent immediately whenever any separate insurance concurrent in form
or contributing in the event of loss with that required to be maintained under
this Section 5.04 is taken out by any Company; and promptly deliver to the
Administrative Agent and the Collateral Agent a duplicate original copy of such
policy or policies.

          (d) Flood Insurance. With respect to each portion of Mortgaged
Property (other than Pipelines) on which improvements are located, obtain flood
insurance in such total amount as the Administrative Agent or the Required
Lenders may from time to time require, if at any time the area in which any
improvements located on any Mortgaged Property is designated a "flood hazard
area" in any Flood Insurance Rate Map published by the Federal Emergency
Management Agency (or any successor agency), and otherwise comply with the

respect to such insurance and such supplemental reports with respect thereto as
the Administrative Agent or the Collateral Agent may from time to time
reasonably request.

Property shall take any action that is reasonably likely to be the basis for
termination, revocation or denial of any

                                      -80-

<PAGE>

insurance coverage required to be maintained under such Loan Party's respective
Mortgage or that could be the basis for a defense to any claim under any
Insurance Policy maintained in respect of the Premises, and each Loan Party
shall otherwise comply in all material respects with all Insurance Requirements
in respect of the Premises; provided, however, that each Loan Party may, at its
own expense and after written notice to the Administrative Agent, (i) contest
the applicability or enforceability of any such Insurance Requirements by
appropriate legal proceedings, the prosecution of which does not constitute a
basis for cancellation or revocation of any insurance coverage required under
this Section 5.04 or (ii) cause the Insurance Policy containing any such
Insurance Requirement to be replaced by a new policy complying with the
provisions of this Section 5.04.

          SECTION 5.05 OBLIGATIONS AND TAXES.

Documents, pay its Indebtedness and other obligations promptly and in accordance
with their terms and pay and discharge promptly when due all Taxes, assessments
and governmental charges or levies imposed upon it or upon its income or profits
or in respect of its property, before the same shall become delinquent or in
default, as well as all lawful claims for labor, services, materials and
supplies or otherwise that, if unpaid, might give rise to a Lien other than a
Permitted Lien upon such properties or any part thereof; provided that such
payment and discharge shall not be required with respect to any such Tax,
assessment, charge, levy, claim, Indebtedness or obligation so long as (x)(i)
the validity or amount thereof shall be contested in good faith by appropriate
proceedings timely instituted and diligently conducted and the applicable
Company shall have set aside on its books adequate reserves or other appropriate
provisions with respect thereto in accordance with GAAP, (ii) such contest
operates to suspend collection of the contested obligation, Tax, assessment or
charge and enforcement of a Lien other than a Permitted Lien and (iii) in the
case of Collateral, the applicable Company shall have otherwise complied with

reasonably be expected to result in a Material Adverse Effect.

          (b) Filing of Returns. Timely file or cause to be filed all material
Tax Returns required to be filed by it.

          (c) Tax Shelter Reporting. Borrower does not intend to treat the Loans

Section 1.6011-4. In the event Borrower determines to take any action
inconsistent with such intention, it will promptly notify the Administrative
Agent thereof.

          SECTION 5.06 EMPLOYEE BENEFITS.

actions necessary to cause such Lien to be duly perfected to the extent required
by such Security Document in accordance with all applicable Requirements of Law,
including the filing of financing statements in such jurisdictions as may be
reasonably requested by the Administrative Agent. Borrower shall otherwise take
such actions and execute and/or deliver to the Collateral Agent such documents
as the Administrative Agent or the Collateral Agent shall reasonably require to
confirm the validity, perfection and priority of the Lien of the Security
Documents against such after-acquired properties.

          (b) Subject to Section 6.14(y), with respect to any person that is or

representing all of the Equity Interests of such Subsidiary, together with
undated stock powers or other appropriate instruments of transfer executed and
delivered in blank by a duly authorized officer of the holder(s) of such Equity

duly authorized officer of such Loan Party and (ii) cause such new Subsidiary
(A) to execute a Joinder Agreement or such comparable documentation to become a

Foreign Subsidiary, execute a security agreement compatible with the laws of
such Foreign Subsidiary's jurisdiction in form and substance reasonably
satisfactory to the Administrative Agent, and (B) to take all actions necessary
or reasonably advisable in the opinion of the Administrative Agent or the
Collateral Agent to cause the Lien created by the applicable Security Agreement

required to be delivered to the Collateral Agent pursuant to clause (i) of this

created or acquired after the Closing Date and (2) no Foreign Subsidiary shall
be required to take the actions specified in clause (ii) of this Section
5.11(b), if, in the case of either clause (1) or (2), doing so would constitute
an investment of earnings in United States property under Section 956 (or a
successor provision) of the Code, which investment would or could reasonably be
expected to trigger a material increase in the net income of a United States
shareholder of such Subsidiary pursuant to Section 951 (or a successor

                                      -83-

100% of the Equity Interests not constituting Voting Stock of any such
Subsidiary, except that any such Equity Interests constituting "stock entitled
to vote" within the meaning of Treasury Regulation Section 1.956-2(c)(2) shall
be treated as Voting Stock for purposes of this Section 5.11(b).

          (c) Promptly grant to the Collateral Agent, within 60 days (subject to
extension in the sole discretion of the Collateral Agent) of the acquisition
thereof, a security interest in and Mortgage on (i) each Real Property owned in
fee by such Loan Party as is acquired by such Loan Party after the Closing Date
and that, together with any improvements thereon, individually has a fair market
value of at least $2.0 million, and (ii) unless the Collateral Agent otherwise
consents, each leased Real Property of such Loan Party which lease individually
has a fair market value of at least $2.0 million, in each case, as additional
security for the Secured Obligations (unless the subject property is already
mortgaged to a third party to the extent permitted by Section 6.02). Such
Mortgages shall be granted pursuant to documentation reasonably satisfactory in
form and substance to the Administrative Agent and the Collateral Agent and
shall constitute valid and enforceable perfected First Priority Liens subject
only to Permitted Collateral Liens or other Liens acceptable to the Collateral
Agent. The Mortgages or instruments related thereto shall be duly recorded or
filed in such manner and in such places as are required by law to establish,
perfect, preserve and protect the Liens in favor of the Collateral Agent
required to be granted pursuant to the Mortgages and all taxes, fees and other
charges payable in connection therewith shall be paid in full. Such Loan Party
shall otherwise take such actions and execute and/or deliver to the Collateral
Agent such documents as the Administrative Agent or the Collateral Agent shall
reasonably require to confirm the validity, perfection and priority of the Lien
of any existing Mortgage or new Mortgage against such after-acquired Real
Property (including a local counsel opinion (in form and substance reasonably
satisfactory to the Administrative Agent and the Collateral Agent) in respect of
such Mortgage).

          (d) Promptly grant to the Collateral Agent, within 60 days (subject to

by such Loan Party as is acquired by such Loan Party after the Closing Date and
that, together with any improvements thereon and any related unmortgaged
Pipeline, has a fair market value of at least $2.0 million, and (ii) unless the
Collateral Agent otherwise consents, each leased Pipeline of such Loan Party
which lease together with any related unmortgaged Pipeline leases has a fair
market value of at least $2.0 million, in each case, as additional security for
the Secured Obligations (unless the subject property is already mortgaged to a
third party to the extent permitted by Section 6.02). Such Mortgages shall be
granted pursuant to documentation reasonably satisfactory in form and substance
to the Administrative Agent and the Collateral Agent and shall constitute valid
and enforceable perfected First Priority Liens subject only to Permitted
Collateral Liens or other Liens acceptable to the Collateral Agent. The
Mortgages or instruments related thereto shall be duly recorded or filed in such
manner and in such places as are required by law to establish, perfect, preserve
and protect the Liens in favor of the Collateral Agent required to be granted
pursuant to the Mortgages and all taxes, fees and other charges payable in
connection therewith shall be paid in full. Such Loan Party shall otherwise take
such actions and execute and/or deliver to the Collateral Agent such documents
as the Administrative Agent or the Collateral Agent shall reasonably require to
confirm the validity, perfection and priority of the Lien of any existing
Mortgage or new Mortgage against such after-acquired Pipeline (including a local
counsel opinion (in form and substance reasonably satisfactory to the
Administrative Agent and the Collateral Agent) in respect of such Mortgage).

the reasonable request of the Administrative Agent, the Collateral Agent or any
Lender, at Borrower's expense, execute, acknowledge and deliver, or cause the
execution, acknowledgment and delivery of, and thereafter register, file or
record, or cause to be registered, filed or recorded, in an appropriate
governmental office, any document or instrument supplemental to or confirmatory
of the Security Documents or otherwise deemed by the Administrative Agent or the
Collateral Agent reasonably necessary or desirable for the continued validity,
perfection and priority of the Liens on the Collateral covered thereby subject
to no other Liens except as permitted by the applicable Security Document, or
obtain any consents or waivers as may be necessary or appropriate in connection
therewith. Deliver or cause to be delivered to the Administrative Agent and the
Collateral Agent from time to time such other documentation, consents,
authorizations, approvals and orders in form and substance reasonably
satisfactory to the Administrative Agent and the Collateral Agent as the
Administrative Agent and the Collateral Agent shall reasonably deem necessary to
perfect or maintain the Liens on the Collateral pursuant to the Security
Documents. Upon the exercise by the Administrative Agent, the Collateral Agent
or any Lender of any power, right, privilege or remedy pursuant to any Loan
Document which requires any consent, approval, registration, qualification or
authorization of any Governmental Authority, execute and deliver all
applications, certifications, instruments and other documents and papers that
the Administrative Agent, the Collateral Agent or such Lender may require. If
the Administrative Agent, the Collateral Agent or the Required Lenders determine
that they are required by a Requirement of Law to have appraisals prepared in
respect of the Real Property of any Loan Party constituting Collateral, Borrower
shall provide to the Administrative Agent appraisals that satisfy the applicable
requirements of the Real Estate Appraisal Reform Amendments of FIRREA and are
otherwise in form and substance reasonably satisfactory to the Administrative
Agent and the Collateral Agent.

connection therewith as the Collateral Agent or the Administrative Agent may

          (c) amend or otherwise change the terms of the Second Lien Loan

                                    GUARANTEE

          SECTION 7.01 THE GUARANTEE. The Guarantors hereby jointly and
severally guarantee, as a primary obligor and not as a surety to each Secured
Party and their respective successors and assigns, the prompt payment in full
when due (whether at stated maturity, by required prepayment, declaration,
demand, by acceleration or otherwise) of the principal of and interest
(including any interest, fees, costs or charges that would accrue but for the
provisions of the Title 11 of the United States Code after any bankruptcy or
insolvency petition under Title 11 of the United States Code) on the Loans made
by the Lenders to, and the Notes held by each Lender of, Borrower, and all other
Secured Obligations from time to time owing to the Secured Parties by any Loan
Party under any Loan Document or any Hedging Agreement entered into with a
counterparty that is a Secured Party, in each case strictly in accordance with
the terms thereof (such obligations being herein collectively called the
"GUARANTEED OBLIGATIONS"). The Guarantors hereby jointly and severally agree
that if Borrower or other Guarantor(s) shall fail to pay in full when due
(whether at stated maturity, by acceleration or otherwise) any of the Guaranteed
Obligations, the Guarantors will promptly pay the same in cash, without any
demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at extended maturity, by acceleration or
otherwise) in accordance with the terms of such extension or renewal.

          SECTION 7.02 OBLIGATIONS UNCONDITIONAL. The obligations of the
Guarantors under Section 7.01 shall constitute a guaranty of payment and to the
fullest extent permitted by applicable Requirements of Law, are absolute,
irrevocable and unconditional, joint and several, irrespective of the value,
genuineness, validity, regularity or enforceability of the Guaranteed
Obligations of Borrower under this Agreement, the Notes, if any, or any other
agreement or instrument referred to herein or therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, irrespective of any other circumstance whatsoever
that might otherwise constitute a legal or equitable discharge or defense of a
surety or Guarantor (except for payment in full). Without limiting the
generality of the foregoing, it is agreed that the occurrence of any one or more
of the following shall not alter or impair the liability of the Guarantors
hereunder which shall remain absolute, irrevocable and unconditional under any
and all circumstances as described above:

          (i) at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

          (ii) any of the acts mentioned in any of the provisions of this
     Agreement or the Notes, if any, or any other agreement or instrument
     referred to herein or therein shall be done or omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be amended in any
     respect, or any right under the Loan Documents or any other agreement or
     instrument referred to herein or therein shall be amended or waived in any
     respect or any other guarantee of any of the Guaranteed Obligations or any
     security therefor shall be released or exchanged in whole or in part or
     otherwise dealt with;

          (iv) any Lien or security interest granted to, or in favor of, Issuing
     Bank or any Lender or Agent as security for any of the Guaranteed
     Obligations shall fail to be perfected; or

                                      -102-

<PAGE>

          (v) the release of any other Guarantor pursuant to Section 7.09.

          The Guarantors hereby expressly waive diligence, presentment, demand
of payment, protest and all notices whatsoever, and any requirement that any
Secured Party exhaust any right, power or remedy or proceed against Borrower
under this Agreement or the Notes, if any, or any other agreement or instrument
referred to herein or therein, or against any other person under any other
guarantee of, or security for, any of the Guaranteed Obligations. The Guarantors
waive any and all notice of the creation, renewal, extension, waiver,
termination or accrual of any of the Guaranteed Obligations and notice of or
proof of reliance by any Secured Party upon this Guarantee or acceptance of this
Guarantee, and the Guaranteed Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred in reliance upon this
Guarantee, and all dealings between Borrower and the Secured Parties shall
likewise be conclusively presumed to have been had or consummated in reliance
upon this Guarantee. This Guarantee shall be construed as a continuing,
absolute, irrevocable and unconditional guarantee of payment without regard to
any right of offset with respect to the Guaranteed Obligations at any time or
from time to time held by Secured Parties, and the obligations and liabilities
of the Guarantors hereunder shall not be conditioned or contingent upon the
pursuit by the Secured Parties or any other person at any time of any right or
remedy against Borrower or against any other person which may be or become
liable in respect of all or any part of the Guaranteed Obligations or against
any collateral security or guarantee therefor or right of offset with respect
thereto. This Guarantee shall remain in full force and effect and be binding in
accordance with and to the extent of its terms upon the Guarantors and the
successors and assigns thereof, and shall inure to the benefit of the Lenders,
and their respective successors and assigns, notwithstanding that from time to
time during the term of this Agreement there may be no Guaranteed Obligations
outstanding.

          SECTION 7.03 REINSTATEMENT. The obligations of the Guarantors under
this Article VII shall be automatically reinstated if and to the extent that for
any reason any payment by or on behalf of Borrower or other Loan Party in
respect of the Guaranteed Obligations is rescinded or must be otherwise restored
by any holder of any of the Guaranteed Obligations, whether as a result of any
proceedings in bankruptcy or reorganization or otherwise.

          SECTION 7.04 SUBROGATION; SUBORDINATION. Each Guarantor hereby agrees
that until the indefeasible payment and satisfaction in full in cash of all
Guaranteed Obligations and the expiration and termination of the Commitments of
the Lenders under this Agreement it shall waive any claim and shall not exercise
any right or remedy, direct or indirect, arising by reason of any performance by
it of its guarantee in Section 7.01, whether by subrogation or otherwise,
against Borrower or any other Guarantor of any of the Guaranteed Obligations or
any security for any of the Guaranteed Obligations. Any Indebtedness of any Loan
Party permitted pursuant to Section 6.01(d) shall be subordinated to such Loan
Party's Secured Obligations in the manner set forth in the Intercompany Note
evidencing such Indebtedness.

          SECTION 7.05 REMEDIES. The Guarantors jointly and severally agree
that, as between the Guarantors and the Lenders, the obligations of Borrower
under this Agreement and the Notes, if any, may be declared to be forthwith due
and payable as provided in Section 8.01 (and shall be deemed to have become
automatically due and payable in the circumstances provided in Section 8.01) for
purposes of Section 7.01, notwithstanding any stay, injunction or other
prohibition preventing such declaration (or such obligations from becoming
automatically due and payable) as against Borrower and that, in the event of
such declaration (or such obligations being deemed to have become automatically
due and payable), such obligations (whether or not due and payable by Borrower)
shall forthwith become due and payable by the Guarantors for purposes of Section
7.01.

<PAGE>

          SECTION 7.06 INSTRUMENT FOR THE PAYMENT OF MONEY. Each Guarantor
hereby acknowledges that the guarantee in this Article VII constitutes an
instrument for the payment of money, and consents and agrees that any Lender or
Agent, at its sole option, in the event of a dispute by such Guarantor in the
payment of any moneys due hereunder, shall have the right to bring a
motion-action under New York CPLR Section 3213.

          SECTION 7.07 CONTINUING GUARANTEE. The guarantee in this Article VII
is a continuing guarantee of payment, and shall apply to all Guaranteed
Obligations whenever arising.

          SECTION 7.08 GENERAL LIMITATION ON GUARANTEE OBLIGATIONS. In any
action or proceeding involving any state corporate limited partnership or
limited liability company law, or any applicable state, federal or foreign
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Guarantor under Section 7.01
would otherwise be held or determined to be void, voidable, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under Section 7.01, then, notwithstanding any
other provision to the contrary, the amount of such liability shall, without any
further action by such Guarantor, any Loan Party or any other person, be
automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding.

          SECTION 7.09 RELEASE OF GUARANTORS. If, in compliance with the terms
and provisions of the Loan Documents, all or substantially all of the Equity
Interests or property of any Guarantor are sold or otherwise transferred (a
"TRANSFERRED Guarantor") to a person or persons, none of which is Borrower or a
Subsidiary, such Transferred Guarantor shall, upon the consummation of such sale
or transfer, be released from its obligations under this Agreement (including
under Section 10.03 hereof) and its obligations to pledge and grant any
Collateral owned by it pursuant to any Security Document and, in the case of a
sale of all or substantially all of the Equity Interests of the Transferred
Guarantor, the pledge of such Equity Interests to the Collateral Agent pursuant
to the Security Agreements shall be released, and the Collateral Agent shall
take such actions as are necessary to effect each release described in this
Section 7.09 in accordance with the relevant provisions of the Security
Documents; provided that such Guarantor is also released from its obligations
under the Second Lien Loan Documents on the same terms.

                                  ARTICLE VIII
                                EVENTS OF DEFAULT

          SECTION 8.01 EVENTS OF DEFAULT. Upon the occurrence and during the
continuance of the following events ("EVENTS OF DEFAULT"):

          (a) default shall be made in the payment of any principal of any Loan
     or any Reimbursement Obligation when and as the same shall become due and

     (whether voluntary or mandatory) thereof or by acceleration thereof or
     otherwise;

          (b) default shall be made in the payment of any interest on any Loan
     or any Fee or any other amount (other than an amount referred to in

     for a period of three Business Days;

                                      -104-

     connection with or pursuant to any Loan Document or the borrowings or

     delivered hereunder, shall prove to have been false or misleading in any
     material respect when so made, deemed made or furnished;

          (d) default shall be made in the due observance or performance by any
     Company of any covenant, condition or agreement contained in Section

     be waived for a period of 30 days after written notice thereof from the
     Administrative Agent or any Lender to Borrower;

          (f) any Company shall (i) fail to pay any principal or interest,
     regardless of amount, due in respect of any Indebtedness (other than the
     Obligations), when and as the same shall become due and payable beyond any
     applicable grace period, or (ii) fail to observe or perform any other term,
     covenant, condition or agreement contained in any agreement or instrument
     evidencing or governing any such Indebtedness if the effect of any failure
     referred to in this clause (ii) is to cause, or to permit the holder or
     holders of such Indebtedness or a trustee or other representative on its or
     their behalf (with or without the giving of notice, the lapse of time or
     both) to cause, such Indebtedness to become due prior to its stated
     maturity or become subject to a mandatory offer purchase by the obligor;
     provided that, other than in the case of the Second Lien Loans, it shall
     not constitute an Event of Default pursuant to this paragraph (f) unless
     the aggregate amount of all such Indebtedness referred to in clauses (i)
     and (ii) exceeds $5.0 million at any one time (provided that, in the case
     of Hedging Obligations, the amount counted for this purpose shall be the
     amount payable by all Companies if such Hedging Obligations were terminated
     at such time);

          (g) an involuntary proceeding shall be commenced or an involuntary
     petition shall be filed in a court of competent jurisdiction seeking (i)
     relief in respect of any Company, or of a substantial part of the property

     any petition seeking relief under Title 11 of the United States Code, as
     now constituted or hereafter amended, or any other federal, state or
     foreign bankruptcy, insolvency, receivership or similar law; (ii) consent

     manner, any proceeding or the filing of any petition described in clause

     or (viii) subject to the rights of Subsidiaries of Borrower under Section
     6.05(e), wind up or liquidate;

          (i) one or more judgments, orders or decrees for the payment of money
     in an aggregate amount in excess of $5.0 million (that are not covered by
     insurance from an insurance company with an A.M. Best financial strength
     rating of at least A-, it being understood that even if such amounts are
     covered by insurance from such an insurance company such amounts shall
     count against such basket if responsibility for such amounts has been
     denied by such insurance company or such insurance company has not been
     promptly notified of such amounts or such insurance company is not
     participating in the defense thereof with customary diligence) shall be
     rendered against any Company or any combination thereof and the same shall
     remain undischarged, unvacated or unbonded for a period of 30 consecutive
     days during which execution shall not be effectively stayed, or any action
     shall be legally taken by a judgment creditor to levy upon properties of
     any Company to enforce any such judgment;

          (j) one or more ERISA Events shall have occurred that, in the opinion
     of the Required Lenders, when taken together with all other such ERISA
     Events, could reasonably be expected to result in a Material Adverse
     Effect;

          (k) any security interest and Lien purported to be created by any
     Security Document with respect to any Collateral worth, individually or in
     the aggregate, in excess of $1.0 million shall cease to be in full force
     and effect, or shall cease to give the Collateral Agent, for the benefit of
     the Secured Parties, the Liens, rights, powers and privileges purported to
     be created and granted under such Security Document (including a perfected
     First Priority security interest in and Lien on all of such Collateral
     (except as otherwise expressly provided in this Agreement or such Security
     Document)) in favor of the Collateral Agent, or shall be asserted by
     Borrower or any other Loan Party not to be a valid, perfected, First
     Priority (except as otherwise expressly provided in this Agreement or such
     Security Document) security interest in or Lien on such Collateral;

          (l) any Loan Document or any material provisions thereof shall at any
     time and for any reason be declared by a court of competent jurisdiction to
     be null and void, or a proceeding shall be commenced by any Loan Party or
     any other person, or by any Governmental Authority, seeking to establish
     the invalidity or unenforceability thereof (exclusive of questions of
     interpretation of any provision thereof), or any Loan Party shall repudiate
     or deny any portion of its liability or obligation for the Obligations; or

          (m) there shall have occurred a Change in Control;

then, and in every such event (other than an event with respect to Holdings or
Borrower described in paragraph (g) or (h) above), and at any time thereafter
during the continuance of such event, the Administrative Agent may, and at the
request of the Required Lenders shall, by notice to Borrower, take either or
both of the following actions, at the same or different times: (i) terminate
forthwith the Commitments and (ii) declare the Loans and Reimbursement
Obligations then outstanding to be forthwith due and payable in whole or in
part, whereupon the principal of the Loans and Reimbursement Obligations so
declared to be due and payable, together with accrued interest thereon and any
unpaid accrued Fees and all other Obligations of Borrower accrued hereunder and
under any other Loan Document, shall become forthwith due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived by Borrower and the Guarantors, anything contained
herein or in any other Loan

                                      -106-

<PAGE>

Document to the contrary notwithstanding; and in any event, with respect to
Holdings or Borrower described in paragraph (g) or (h) above, the Commitments
shall automatically terminate and the principal of the Loans and Reimbursement
Obligations then outstanding, together with accrued interest thereon and any
unpaid accrued Fees and all other Obligations of Borrower accrued hereunder and
under any other Loan Document, shall automatically become due and payable,
without presentment, demand, protest or any other notice of any kind, all of
which are hereby expressly waived by Borrower and the Guarantors, anything
contained herein or in any other Loan Document to the contrary notwithstanding.

          SECTION 8.02 RESCISSION. If at any time after termination of the
Commitments or acceleration of the maturity of the Loans, Borrower shall pay all
arrears of interest and all payments on account of principal of the Loans and
Reimbursement Obligations owing by it that shall have become due otherwise than
by acceleration (with interest on principal and, to the extent permitted by law,
on overdue interest, at the rates specified herein) and all Defaults (other than
non-payment of principal of and accrued interest on the Loans due and payable
solely by virtue of acceleration) shall be remedied or waived pursuant Section
10.02, then upon the written consent of the Required Lenders and written notice
to Borrower, the termination of the Commitments or the acceleration and their
consequences may be rescinded and annulled; but such action shall not affect any
subsequent Default or impair any right or remedy consequent thereon. The
provisions of the preceding sentence are intended merely to bind the Lenders and
the Issuing Bank to a decision that may be made at the election of the Required
Lenders, and such provisions are not intended to benefit Borrower and do not
give Borrower the right to require the Lenders to rescind or annul any
acceleration hereunder, even if the conditions set forth herein are met.

          SECTION 8.03 APPLICATION OF PROCEEDS. The proceeds received by the
Collateral Agent in respect of any sale of, collection from or other realization
upon all or any part of the Collateral pursuant to the exercise by the
Collateral Agent of its remedies shall be applied, in full or in part, together
with any other sums then held by the Collateral Agent pursuant to this
Agreement, promptly by the Collateral Agent as follows:

          (a) First, to the payment of all reasonable costs and expenses, fees,
     commissions and taxes of such sale, collection or other realization
     including compensation to the Collateral Agent and its agents and counsel,
     and all expenses, liabilities and advances made or incurred by the
     Collateral Agent in connection therewith and all amounts for which the
     Collateral Agent is entitled to indemnification pursuant to the provisions
     of any Loan Document, together with interest on each such amount at the
     highest rate then in effect under this Agreement from and after the date
     such amount is due, owing or unpaid until paid in full;

          (b) Second, to the payment of all other reasonable costs and expenses
     of such sale, collection or other realization including compensation to the
     other Secured Parties and their agents and counsel and all costs,
     liabilities and advances made or incurred by the other Secured Parties in
     connection therewith, together with interest on each such amount at the
     highest rate then in effect under this Agreement from and after the date
     such amount is due, owing or unpaid until paid in full;

          (c) Third, without duplication of amounts applied pursuant to clauses
     (a) and (b) above, to the indefeasible payment in full in cash, pro rata,
     of interest and other amounts constituting Obligations (other than
     principal and Reimbursement Obligations) and any fees, premiums and
     scheduled periodic payments due under Hedging Agreements constituting
     Secured Obligations and any interest accrued thereon, in each case equally
     and ratably in accordance with the respective amounts thereof then due and
     owing;

                                      -107-

<PAGE>

          (d) Fourth, to the indefeasible payment in full in cash, pro rata, of
     principal amount of the Obligations (including Reimbursement Obligations)
     and any breakage, termination or other payments under Hedging Agreements
     constituting Secured Obligations and any interest accrued thereon; and

          (e) Fifth, the balance, if any, to the person lawfully entitled
     thereto (including the applicable Loan Party or its successors or assigns)
     or as a court of competent jurisdiction may direct.

          In the event that any such proceeds are insufficient to pay in full
the items described in clauses (a) through (e) of this Section 8.03, the Loan
Parties shall remain liable, jointly and severally, for any deficiency. Each
Loan Party acknowledges the relative rights, priorities and agreements of the
Secured Parties and the Second Lien Secured Parties, as set forth in the
Intercreditor Agreement and this Agreement, including as set forth in this
Section 8.03.

          SECTION 8.04 Holdings' Right to Cure.

          (a) Cure Right Mechanics. Notwithstanding anything to the contrary
contained in Section 8.01, in the event that Borrower fails to comply with the
requirements of Section 6.10(a), (b) or (c), until the expiration of the 10th
day subsequent to the date the certificate calculating such covenant is required
to be delivered pursuant to Section 5.01(c), Holdings shall have the right to
issue Permitted Cure Securities for cash or otherwise receive cash contributions
to the capital of Holdings, and, in each case, to contribute any such cash to
the capital of Borrower (collectively, the "CURE RIGHT"), and upon the receipt
by Borrower of such cash (the "CURE AMOUNT") pursuant to the exercise by
Holdings of such Cure Right such covenant shall be recalculated giving effect to
the following pro forma adjustments:

          (i) if such Cure Right is exercised with respect to (x) Section
     6.10(a) or (b), Consolidated EBITDA shall be increased, solely for the
     purpose of measuring such covenants and not for any other purpose under
     this Agreement, by an amount equal to the Cure Amount and (y) Section
     6.10(c), the amount of Capital Expenditures allowed for such period shall
     be increased, solely for the purpose of measuring such covenants and not
     for any other purpose under this Agreement, by an amount equal to the Cure
     Amount; and

          (ii) If, after giving effect to the foregoing recalculations, Holdings
     shall then be in compliance with the requirements of all such covenants,
     Holdings shall be deemed to have satisfied the requirements of such
     covenants as of the relevant date of determination with the same effect as
     though there had been no failure to comply therewith at such date, and the
     applicable breach or default of either such covenant that had occurred
     shall be deemed cured for this purposes of the Agreement.

          (b) Limitation on Exercise of Cure Right. Notwithstanding anything
herein to the contrary, (a) in each four-fiscal-quarter period there shall be at
least one fiscal quarter in which the Cure Right is not exercised, (b) in each
eight-fiscal-quarter period, there shall be a period of at least four
consecutive fiscal quarters during which the Cure Right is not exercised and (c)
the Cure Amount shall be no greater than the amount required for purposes of
complying with such covenants.

                                   ARTICLE IX
                THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

          SECTION 9.01 APPOINTMENT AND AUTHORITY. Each of the Lenders and the
Issuing Bank hereby irrevocably appoints UBS AG, Stamford Branch, to act on its
behalf as the Administrative Agent and the Collateral Agent hereunder and under
the other Loan Documents and authorizes such Agents to take such actions on its
behalf and to exercise such powers as are delegated to such Agents by the terms
hereof or thereof, together with such actions and powers as are reasonably
incidental thereto. The provisions of this Article are solely for the benefit of
the Administrative Agent, the Collateral Agent, the Lenders and the Issuing
Bank, and neither Borrower nor any other Loan Party shall have rights as a third
party beneficiary of any of such provisions.

          SECTION 9.02 RIGHTS AS A LENDER. Each person serving as an Agent
hereunder shall have the same rights and powers in its capacity as a Lender as
any other Lender and may exercise the same as though it were not an Agent and
the term "Lender" or "Lenders" shall, unless otherwise expressly indicated or
unless the context otherwise requires, include each person serving as an Agent
hereunder in its individual capacity. Such person and its Affiliates may accept
deposits from, lend money to, act as the financial advisor or in any other
advisory capacity for and generally engage in any kind of business with Borrower
or any Subsidiary or other Affiliate thereof as if such person were not an Agent
hereunder and without any duty to account therefor to the Lenders.

          SECTION 9.03 EXCULPATORY PROVISIONS(a). No Agent shall have any
duties or obligations except those expressly set forth herein and in the other
Loan Documents. Without limiting the generality of the foregoing, no Agent:

          (i) shall be subject to any fiduciary or other implied duties,
     regardless of whether a Default has occurred and is continuing;

          (ii) shall have any duty to take any discretionary action or exercise
     any discretionary powers, except discretionary rights and powers expressly
     contemplated hereby or by the other Loan Documents that such Agent is
     required to exercise as directed in writing by the Required Lenders (or
     such other number or percentage of the Lenders as shall be expressly
     provided for herein or in the other Loan Documents); provided that such
     Agent shall not be required to take any action that, in its judgment or the
     judgment of its counsel, may expose such Agent to liability or that is
     contrary to any Loan Document or applicable Requirements of Law; and

          (iii) shall, except as expressly set forth herein and in the other
     Loan Documents, have any duty to disclose, and shall not be liable for the
     failure to disclose, any information relating to Borrower or any of its
     Affiliates that is communicated to or obtained by the person serving as
     such Agent or any of its Affiliates in any capacity.

No Agent shall be liable for any action taken or not taken by it (x) with the
consent or at the request of the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary, or as such Agent shall believe
in good faith shall be necessary, under the circumstances as provided in Section
10.02) or (y) in the absence of its own gross negligence or willful misconduct.
No Agent shall be deemed to have knowledge of any Default unless and until
notice describing such Default is given to such Agent by Borrower, a Lender or
the Issuing Bank.

                                      -109-

<PAGE>

          No Agent shall be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement or any other Loan Document, (ii) the contents of
any certificate, report or other document delivered hereunder or thereunder or
in connection herewith or therewith, (iii) the performance or observance of any
of the covenants, agreements or other terms or conditions set forth herein or
therein or the occurrence of any Default, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document or any
other agreement, instrument or document or (v) the satisfaction of any condition
set forth in Article IV or elsewhere herein, other than to confirm receipt of
items expressly required to be delivered to such Agent. Without limiting the
generality of the foregoing, the use of the term "agent" in this Agreement with
reference to the Administrative Agent or the Collateral Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law. Instead, such term us used merely as a
matter of market custom and is intended to create or reflect only an
administrative relationship between independent contracting parties.

          SECTION 9.04 RELIANCE BY AGENT. Each Agent shall be entitled to rely
upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing
(including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or
otherwise authenticated by the proper person. Each Agent also may rely upon any
statement made to it orally or by telephone and believed by it to have been made
by the proper person, and shall not incur any liability for relying thereon. In
determining compliance with any condition hereunder to the making of a Loan, or
the issuance of a Letter of Credit, that by its terms must be fulfilled to the
satisfaction of a Lender or the Issuing Bank, the Administrative Agent may
presume that such condition is satisfactory to such Lender or the Issuing Bank
unless the Administrative Agent shall have received notice to the contrary from
such Lender or the Issuing Bank prior to the making of such Loan or the issuance
of such Letter of Credit. Each Agent may consult with legal counsel (who may be
counsel for Borrower), independent accountants and other experts selected by it,
and shall not be liable for any action taken or not taken by it in accordance
with the advice of any such counsel, accountants or experts.

          SECTION 9.05 DELEGATION OF DUTIES. Each Agent may perform any and all
of its duties and exercise its rights and powers hereunder or under any other
Loan Document by or through any one or more sub-agents appointed by such Agent.
Each Agent and any such sub-agent may perform any and all of its duties and
exercise its rights and powers by or through their respective Related Parties.
The exculpatory provisions of this Article shall apply to any such sub-agent and
to the Related Parties of each Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Agent.

          SECTION 9.06 RESIGNATION OF AGENT. Each Agent may at any time give
notice of its resignation to the Lenders, the Issuing Bank and Borrower. Upon
receipt of any such notice of resignation, the Required Lenders shall have the
right, in consultation with Borrower, to appoint a successor, which shall be a
bank with an office in the United States, or an Affiliate of any such bank with
an office in the United States. If no such successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation, then
the retiring Agent may on behalf of the Lenders and the Issuing Bank, appoint a
successor Agent meeting the qualifications set forth above provided that if the
Agent shall notify Borrower and the Lenders that no qualifying person has
accepted such appointment, then such resignation shall nonetheless become
effective in accordance with such notice and (1) the retiring Agent shall be
discharged from its duties and obligations hereunder and under the other Loan
Documents (except that in the case of any collateral security held by the
Collateral Agent on behalf of the Lenders or the Issuing Bank under any of the

                                      -110-

<PAGE>

Loan Documents, the retiring Collateral Agent shall continue to hold such
collateral security as nominee until such time as a successor Collateral Agent
is appointed) and (2) all payments, communications and determinations provided
to be made by, to or through an Agent shall instead be made by or to each Lender
and the Issuing Bank directly, until such time as the Required Lenders appoint a
successor Agent as provided for above in this paragraph. Upon the acceptance of
a successor's appointment as Agent hereunder, such successor shall succeed to
and become vested with all of the rights, powers, privileges and duties of the
retiring (or retired) Agent, and the retiring Agent shall be discharged from all
of its duties and obligations hereunder or under the other Loan Documents (if
not already discharged therefrom as provided above in this paragraph). The fees
payable by Borrower to a successor Agent shall be the same as those payable to
its predecessor unless otherwise agreed between Borrower and such successor.
After the retiring Agent's resignation hereunder and under the other Loan
Documents, the provisions of this Article IX and Section 10.03 shall continue in
effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while the retiring Agent was acting as Agent.

          SECTION 9.07 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender and
the Issuing Bank acknowledges that it has, independently and without reliance
upon any Agent or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender and the Issuing Bank also acknowledges that it
will, independently and without reliance upon any Agent or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement, any other Loan Document or any related
agreement or any document furnished hereunder or thereunder.

          SECTION 9.08 NO OTHER DUTIES, ETC.; APPOINTMENT. Anything herein to
the contrary notwithstanding, none of the Bookmanagers, Arrangers, Syndication
Agent or Documentation Agents listed on the cover page hereof shall have any
powers, duties or responsibilities under this Agreement or any of the other Loan
Documents, except in its capacity, as applicable, as the Administrative Agent,
the Collateral Agent, a Lender or the Issuing Bank hereunder. The Administrative
Agent and Borrower may appoint additional or different Syndication Agents and
Documentation Agents and amend (or amend and restate) this Agreement to reflect
such appointments without the approval of any Lender other than any resigning
Syndication Agent or Documentation Agent.

          SECTION 9.09 INTERCREDITOR AGREEMENT. Notwithstanding anything herein
to the contrary, each Lender also acknowledges that the Lien and security
interest granted to the Collateral Agent pursuant to the Security Documents and
the exercise of any right or remedy by the Collateral Agent thereunder are
subject to the provisions of the Intercreditor Agreement. In the event of any
conflict between the terms of the Intercreditor Agreement and the Security
Documents, the terms of the Intercreditor Agreement shall govern and control.

          (b) Electronic Communications. Notices and other communications to the
Lenders and the Issuing Bank hereunder may (subject to Section 10.01(d)) be
delivered or furnished by electronic communication (including e-mail and
Internet or intranet websites) pursuant to procedures approved by the
Administrative Agent; provided that the foregoing shall not apply to notices to
any Lender or the Issuing Bank pursuant to Article II if such Lender or the
Issuing Bank, as applicable, has notified the Administrative Agent that it is
incapable of receiving notices under such Article by electronic communication.
The Administrative Agent, the Collateral Agent or Borrower may, in its
discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it (including as

          (c) Change of Address, Etc. Any party hereto may change its address or
telecopier number for notices and other communications hereunder by notice to

          (d) Posting. Each Loan Party hereby agrees that it will provide to the
Administrative Agent all information, documents and other materials that it is
obligated to furnish to the Administrative Agent pursuant to this Agreement and
any other Loan Document, including all notices, requests, financial statements,
financial and other reports, certificates and other information materials, but
excluding any such communication that (i) relates to a request for a new, or a

election of an interest rate or interest period relating thereto), (ii) relates
to the payment of any principal or other amount due under this Agreement prior
to the scheduled date therefor, (iii) provides notice of any Default under this
Agreement or (iv) is required to be delivered to satisfy any condition precedent
to the effectiveness of this Agreement and/or any borrowing or

                                     -113-

<PAGE>

other extension of credit hereunder (all such non-excluded communications,
collectively, the "COMMUNICATIONS"), by transmitting the Communications in an
electronic/soft medium in a format reasonably acceptable to the Administrative
Agent at christopher.aitkin@ubs.com or at such other e-mail address(es) provided
to Borrower from time to time or in such other form, including hard copy
delivery thereof, as the Administrative Agent shall require. In addition, each
Loan Party agrees to continue to provide the Communications to the
Administrative Agent in the manner specified in this Agreement or any other Loan
Document or in such other form, including hard copy delivery thereof, as the
Administrative Agent shall require. Nothing in this Section 10.01 shall
prejudice the right of the Agents, any Lender or any Loan Party to give any
notice or other communication pursuant to this Agreement or any other Loan
Document in any other manner specified in this Agreement or any other Loan
Document or as any such Agent shall require.

          To the extent consented to by the Administrative Agent in writing from
time to time, Administrative Agent agrees that receipt of the Communications by
the Administrative Agent at its e-mail address(es) set forth above shall
constitute effective delivery of the Communications to the Administrative Agent
for purposes of the Loan Documents; provided that Borrower shall also deliver to
the Administrative Agent an executed original of each Compliance Certificate
required to be delivered hereunder.

          Each Loan Party further agrees that Administrative Agent may make the
Communications available to the Lenders by posting the Communications on
Intralinks or a substantially similar electronic transmission system (the
"PLATFORM"). The Platform is provided "as is" and "as available." The Agents do
not warrant the accuracy or completeness of the Communications, or the adequacy
of the Platform and expressly disclaim liability for errors or omissions in the
communications. No warranty of any kind, express, implied or statutory,
including, without limitation, any warranty of merchantability, fitness for a
particular purpose, non-infringement of third party rights or freedom from
viruses or other code defects, is made by any Agent in connection with the
Communications or the Platform. In no event shall the Administrative Agent or
any of its Related Parties have any liability to the Loan Parties, any Lender or
any other person for damages of any kind, including direct or indirect, special,
incidental or consequential damages, losses or expenses (whether in tort,
contract or otherwise) arising out of any Loan Party's or the Administrative
Agent's transmission of communications through the Internet, except to the
extent the liability of such person is found in a final non-appealable judgment
by a court of competent jurisdiction to have resulted from such person's gross
negligence or willful misconduct.

          SECTION 10.02 WAIVERS; AMENDMENT.

          (a) Generally. No failure or delay by any Agent, the Issuing Bank or
any Lender in exercising any right or power hereunder or under any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
each Agent, the Issuing Bank and the Lenders hereunder and under the other Loan
Documents are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of any Loan Document or
consent to any departure by any Loan Party therefrom shall in any event be
effective unless the same shall be permitted by this Section 10.02, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. Without limiting the generality of the foregoing,
the making of a Loan or issuance of a Letter of Credit shall not be construed as
a waiver of any Default, regardless of whether any Agent, any Lender or the
Issuing Bank may have had notice or knowledge of such Default at the time. No
notice or demand on Borrower in any case shall entitle Borrower to any other or
further notice or demand in similar or other circumstances.

                                     -114-

          (b) Required Consents. Subject to Sections 10.02(c) and (d) and the
Intercreditor Agreement, neither this Agreement nor any other Loan Document nor
any provision hereof or thereof may be waived, amended, supplemented or modified
except, in the case of this Agreement, pursuant to an agreement or agreements in
writing entered into by Borrower and the Required Lenders or, in the case of any
other Loan Document, pursuant to an agreement or agreements in writing entered
into by the Administrative Agent, the Collateral Agent (in the case of any
Security Document) and the Loan Party or Loan Parties that are party thereto, in
each case with the written consent of the Required Lenders; provided that no
such agreement shall be effective if the effect thereof would:

          (i) increase the Commitment of any Lender without the written consent
     of such Lender (it being understood that no amendment, modification,
     termination, waiver or consent with respect to any condition precedent,
     covenant or Default shall constitute an increase in the Commitment of any
     Lender);

          (ii) reduce the principal amount of any Loan or LC Disbursement or
     reduce the rate of interest thereon (other than interest pursuant to
     Section 2.06(c)), or reduce any Fees payable hereunder, or change the form
     or currency of payment of any Obligation, without the written consent of
     each Lender directly affected thereby (it being understood that any
     amendment or modification to the financial definitions in this Agreement
     shall not constitute a reduction in the rate of interest for purposes of
     this clause (ii));

          (iii) (A) change the scheduled final maturity of any Loan, (B)
     postpone the date for payment of any Reimbursement Obligation or any
     interest or fees payable hereunder, (C) change the amount of, waive or
     excuse any such payment (other than waiver of any increase in the interest
     rate pursuant to Section 2.06(c)), or (D) postpone the scheduled date of
     expiration of any Commitment or any Letter of Credit beyond the Revolving
     Maturity Date, in any case, without the written consent of each Lender
     directly affected thereby;

          (iv) increase the maximum duration of Interest Periods hereunder,
     without the written consent of each Lender directly affected thereby;

          (v) permit the assignment or delegation by Borrower of any of its
     rights or obligations under any Loan Document, without the written consent
     of each Lender;

          (vi) release Holdings or all or substantially all of the Subsidiary
     Guarantors from their Guarantee (except as expressly provided in Article
     VII), or limit their liability in respect of such Guarantee, without the
     written consent of each Lender;

          (vii) release all or substantially all of the Collateral from the
     Liens of the Security Documents or alter the relative priorities of the
     Secured Obligations entitled to the Liens of the Security Documents, in
     each case without the written consent of each Lender (it being understood
     that additional Classes of Loans pursuant to Sections 2.19 and 2.20 or
     consented to by the Required Lenders may be equally and ratably secured by
     the Collateral with the then existing Secured Obligations under the
     Security Documents);

          (viii) change Section 2.14(b) or (c) in a manner that would alter the
     pro rata sharing of payments or setoffs required thereby or any other
     provision in a manner that would alter the pro rata allocation among the
     Lenders of Loan disbursements, including the requirements of Sections
     2.02(a), 2.17(d) and 2.18(d), without the written consent of each Lender
     directly affected thereby;

                                     -115-

<PAGE>

          (ix) change any provision of this Section 10.02(b) or Section 10.02(c)
     or (d), without the written consent of each Lender directly affected
     thereby (except for additional restrictions on amendments or waivers for
     the benefit of Lenders of additional Classes of Loans pursuant to Section
     2.19 or consented to by the Required Lenders);

          (x) change the percentage set forth in the definition of "Required
     Lenders," "Required Class Lenders," "Required Revolving Lenders" or any
     other provision of any Loan Document (including this Section) specifying
     the number or percentage of Lenders (or Lenders of any Class) required to
     waive, amend or modify any rights thereunder or make any determination or
     grant any consent thereunder, without the written consent of each Lender
     (or each Lender of such Class, as the case may be), other than to increase
     such percentage or number or to give any additional Lender or group of
     Lenders such right to waive, amend or modify or make any such determination
     or grant any such consent;

          (xi) change the application of prepayments as among or between Classes
     under Section 2.10(h), without the written consent of the Required Class
     Lenders of each Class that is being allocated a lesser prepayment as a
     result thereof (it being understood that the Required Lenders may waive, in
     whole or in part, any prepayment so long as the application, as between
     Classes, of any portion of such prepayment that is still required to be
     made is not changed and, if additional Classes of Term Loans under this
     Agreement pursuant to Section 2.19 or consented to by the Required Lenders
     are made, such new Term Loans may be included on a pro rata basis in the
     various prepayments required pursuant to Section 2.10(h));

          (xii) change or waive any provision of Article X as the same applies
     to any Agent, or any other provision hereof as the same applies to the
     rights or obligations of any Agent, in each case without the written
     consent of such Agent;

          (xiii) change or waive any obligation of the Lenders relating to the
     issuance of or purchase of participations in Letters of Credit, without the
     written consent of the Required Revolving Lenders, the Administrative Agent
     and the Issuing Bank;

          (xiv) change or waive any provision hereof relating to Swingline Loans
     (including the definition of "Swingline Commitment"), without the written
     consent of the Swingline Lender;

          (xv) expressly change or waive any condition precedent in Section 4.02
     to any Revolving Borrowing without the written consent of the Required
     Revolving Lenders; or

          (xvi) change or waive any provision affecting rights applicable only
     to Lenders holding New Term Loan Commitments without the written consent of
     the Lenders holding a majority of the New Term Loan Commitments;

provided, further, that

          (1) any waiver, amendment or modification prior to the achievement of
     a Successful Syndication may not be effected without the written consent of
     the Arranger (such consent not to be unreasonably withheld or delayed); and

          (2) any waiver, amendment or modification of the Intercreditor
     Agreement (and any related definitions) may be effected by an agreement or
     agreements in writing entered into among the Collateral Agent, the
     Administrative Agent, the Required Lenders and the Required Second

                                     -116-

<PAGE>

     Lien Lenders (without the consent of any Loan Party, so long as such
     amendment, waiver or modification does not impose any additional duties or
     obligations on the Loan Parties or alter or impair any right of any Loan
     Party under the Loan Documents or adversely affect any Loan Party).

Notwithstanding anything in this Section 10.02 to the contrary, any Increase
Joinder or Revolving Loan Joinder may, without the consent of any Lenders other
than those participating in such joinder, effect such amendments to this
Agreement and the other Loan Documents as may be necessary or appropriate, in
the opinion of the Administrative Agent, to effect the provisions of Section
2.19 or 2.20, as applicable.

          (c) Collateral. Without the consent of any other person, the
applicable Loan Party or Parties and the Administrative Agent and/or Collateral
Agent may (in its or their respective sole discretion, or shall, to the extent
required by any Loan Document) enter into any amendment or waiver of any Loan
Document, or enter into any new agreement or instrument, to effect the granting,
perfection, protection, expansion or enhancement of any security interest in any
Collateral or additional property to become Collateral for the benefit of the
Secured Parties, or as required by local law to give effect to, or protect any
security interest for the benefit of the Secured Parties, in any property or so
that the security interests therein comply with applicable Requirements of Law.

          (d) Dissenting Lenders. If, in connection with any proposed change,
waiver, discharge or termination of the provisions of this Agreement as
contemplated by Section 10.02(b), the consent of the Required Lenders is
obtained but the consent of one or more of such other Lenders whose consent is
required is not obtained, then Borrower shall have the right to replace such
non-consenting Lender or Lenders, so long as all non-consenting Lenders are so
replaced (or, at the option of Borrower if the respective non-consenting
Lenders' consent is required with respect to less than all Classes of Loans (or
related Commitments), to replace only the Commitments and/or Loans of the
respective non-consenting Lender that gave rise to the need to obtain such
Lender's individual consent), with one or more persons pursuant to Section 2.16
so long as at the time of such replacement each such new Lender consents to the
proposed change, waiver, discharge or termination.

          SECTION 10.03 EXPENSES; INDEMNITY; DAMAGE WAIVER.

          (a) Costs and Expenses. Borrower shall pay (i) all reasonable
out-of-pocket expenses incurred by the Administrative Agent, the Collateral
Agent and their respective Affiliates (including the reasonable fees, charges
and disbursements of counsel, and local counsel who specialize in gas and
pipeline matters, for the Administrative Agent and/or the Collateral Agent) in
connection with the syndication of the credit facilities provided for herein
(including the obtaining and maintaining of CUSIP numbers for the Loans), the
preparation, negotiation, execution, delivery and administration of this
Agreement and the other Loan Documents or any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable
out-of-pocket expenses incurred by the Issuing Bank in connection with the
issuance, amendment, renewal or extension of any Letter of Credit or any demand
for payment thereunder, (iii) all out-of-pocket expenses incurred by the
Administrative Agent, the Collateral Agent, any Lender or the Issuing Bank
(including the fees, charges and disbursements of any counsel, and local counsel
who specialize in gas and pipeline matters, for the Administrative Agent, the
Collateral Agent, any Lender or the Issuing Bank), in connection with the
enforcement or protection of its rights (A) in connection with this Agreement
and the other Loan Documents, including its rights under this Section 10.03, or
(B) in connection with the Loans made or Letters of Credit issued hereunder,
including all such out-of-pocket expenses

                                     -117-

<PAGE>

incurred during any workout, restructuring or negotiations in respect of such
Loans or Letters of Credit and (iv) all documentary and similar taxes and
charges in respect of the Loan Documents.

          (b) Indemnification by Borrower. Borrower shall indemnify the
Administrative Agent (and any sub-agent thereof), the Collateral Agent (and any
sub-agent thereof) each Lender and the Issuing Bank, and each Related Party of
any of the foregoing persons (each such person being called an "INDEMNITEE")
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including the fees, charges and
disbursements of any counsel, and local counsel who specialize in gas and
pipeline matters, for any Indemnitee) incurred by any Indemnitee or asserted
against any Indemnitee by any third party or by Borrower or any other Loan Party
arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the performance by the parties hereto
of their respective obligations hereunder or thereunder or the consummation of
the transactions contemplated hereby or thereby, (ii) any Loan or Letter of
Credit or the use or proposed use of the proceeds therefrom (including any
refusal by the Issuing Bank to honor a demand for payment under a Letter of
Credit if the documents presented in connection with such demand do not strictly
comply with the terms of such Letter of Credit), (iii) any actual or alleged
presence or Release or threatened Release of Hazardous Materials on, at, under
or from any property owned, leased or operated by any Company at any time, or
any Environmental Claim related in any way to any Company, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory, whether
brought by a third party or by Borrower or any other Loan Party, and regardless
of whether any Indemnitee is a party thereto; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses (x) are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Indemnitee or (y) result from
a claim brought by Borrower or any other Loan Party against an Indemnitee for
breach in bad faith of such Indemnitee's obligations hereunder or under any
other Loan Document, if Borrower or such Loan Party has obtained a final and
nonappealable judgment in its favor on such claim as determined by a court of
competent jurisdiction; provided, further, that Borrower shall not be required
to reimburse the legal fees and expenses of more than one outside counsel (in
addition to any reasonably necessary special counsel and up to one local counsel
in each applicable local jurisdiction) for all Indemnitees unless, in the
reasonable written opinion of outside counsel to such Indemnitees,
representation of all such Indemnitees would be inappropriate due to the
existence of an actual or potential conflict of interest.

          (c) Reimbursement by Lenders. To the extent that Borrower for any
reason fails to indefeasibly pay any amount required under paragraph (a) or (b)
of this Section 10.03 to be paid by it to the Administrative Agent (or any
sub-agent thereof), the Collateral Agent, the Issuing Bank, the Swingline Lender
or any Related Party of any of the foregoing, each Lender severally agrees to
pay to the Administrative Agent (or any such sub-agent), the Collateral Agent
(or any sub-agent thereof), the Issuing Bank, the Swingline Lender or such
Related Party, as the case may be, such Lender's pro rata share (determined as
of the time that the applicable unreimbursed expense or indemnity payment is
sought) of such unpaid amount; provided that the unreimbursed expense or
indemnified loss, claim, damage, liability or related expense, as the case may
be, was incurred by or asserted against the Administrative Agent (or any such
sub-agent), the Collateral Agent (or any sub-agent thereof), the Swingline
Lender or the Issuing Bank in its capacity as such, or against any Related Party
of any of the foregoing acting for the Administrative Agent (or any such
sub-agent), the Collateral Agent (or any sub-agent thereof), the Swingline
Lender or Issuing Bank in connection with such capacity. The obligations of the
Lenders under this paragraph (c) are subject to the provisions of Section 2.14.
For purposes hereof, a Lender's "pro rata share"

                                     -118-

<PAGE>

shall be determined based upon its share of the sum of the total Revolving
Exposure, outstanding Term Loans and unused Commitments at the time.

          (d) Waiver of Consequential Damages, Etc. To the fullest extent
permitted by applicable Requirements of Law, no Loan Party shall assert, and
each Loan Party hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as a
result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby, the transactions contemplated hereby or thereby,
any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee
referred to in paragraph (b) above shall be liable for any damages arising from
the use by unintended recipients of any information or other materials
distributed by it through telecommunications, electronic or other information
transmission systems in connection with this Agreement or the other Loan
Documents or the transactions contemplated hereby or thereby.

          (e) Payments. All amounts due under this Section shall be payable not
later than 3 Business Days after demand therefor.

          SECTION 10.04 SUCCESSORS AND ASSIGNS.

          (a) Successors and Assigns Generally. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that Borrower may not
assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of the Administrative Agent, the Collateral Agent, the
Issuing Lender, the Swingline Lender and each Lender and no Lender may assign or
otherwise transfer any of its rights or obligations hereunder except (i) to an
Eligible Assignee in accordance with the provisions of paragraph (b) of this
Section 10.04, (ii) by way of participation in accordance with the provisions of
paragraph (d) of this Section 10.04 or (iii) by way of pledge or assignment of a
security interest subject to the restrictions of paragraph (f) of this Section
(and any other attempted assignment or transfer by Borrower or any Lender shall
be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any person (other than the parties hereto, their
respective successors and assigns permitted hereby, Participants to the extent
provided in paragraph (d) of this Section and, to the extent expressly
contemplated hereby, the other Indemnitees) any legal or equitable right, remedy
or claim under or by reason of this Agreement.

          (b) Assignments by Lenders. Any Lender may at any time assign to one
or more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it); provided that

          (i) except in the case of any assignment made in connection with the
     primary syndication of the Commitment and Loans by the Arranger or an
     assignment of the entire remaining amount of the assigning Lender's
     Commitment and the Loans at the time owing to it or in the case of an
     assignment to a Lender or an Affiliate of a Lender or an Approved Fund with
     respect to a Lender, the aggregate amount of the Commitment (which for this
     purpose includes Loans outstanding thereunder) or, if the applicable
     Commitment is not then in effect, the principal outstanding balance of the
     Loans of the assigning Lender subject to each such assignment (determined
     as of the date the Assignment and Assumption with respect to such
     assignment is delivered to the Administrative Agent or, if "Trade Date" is
     specified in the Assignment and Assumption, as of the Trade Date) shall not
     be less than $5.0 million, in the case of any assignment in respect of
     Revolving Loans and/or Revolving Commitments, or $1.0 million, in the case
     of any assignment

                                     -119-

<PAGE>

     in respect of Term Loans and/or Term Loan Commitments, unless each of the
     Administrative Agent and, so long as no Event of Default has occurred and
     is continuing, Borrower otherwise consent (each such consent not to be
     unreasonably withheld or delayed);

          (ii) each partial assignment shall be made as an assignment of a
     proportionate part of all the assigning Lender's rights and obligations
     under this Agreement with respect to the Loan or the Commitment assigned,
     except that this clause (ii) shall not prohibit any Lender from assigning
     all or a portion of its rights and obligations among separate tranches on a
     non-pro rata basis; and

          (iii) the parties to each assignment shall execute and deliver to the
     Administrative Agent an Assignment and Assumption, together with a
     processing and recordation fee of $3,500, and the Eligible Assignee, if it
     shall not be a Lender, shall deliver to the Administrative Agent an
     Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant
to paragraph (c) of this Section 10.04, from and after the effective date
specified in each Assignment and Assumption, the Eligible Assignee thereunder
shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto) but shall continue
to be entitled to the benefits of Sections 2.12, 2.13, 2.15 and 10.03 with
respect to facts and circumstances occurring prior to the effective date of such
assignment. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this paragraph shall be treated
for purposes of this Agreement as a sale by such Lender of a participation in
such rights and obligations in accordance with paragraph (d) of this Section
10.04.

          (c) Register. The Administrative Agent, acting solely for this purpose
as an agent of Borrower, shall maintain at one of its offices in Stamford,
Connecticut a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the
Commitments of, and principal amounts of the Loans and LC Disbursements owing
to, each Lender pursuant to the terms hereof from time to time (the "REGISTER").
The entries in the Register shall be conclusive, and Borrower, the
Administrative Agent, the Issuing Bank and the Lenders shall treat each person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by Borrower, the
Issuing Bank, the Collateral Agent, the Swingline Lender and any Lender (with
respect to its own interest only), at any reasonable time and from time to time
upon reasonable prior notice.

          (d) Participations. Any Lender may at any time, without the consent
of, or notice to, Borrower, the Administrative Agent, the Issuing Bank or the
Swingline Lender sell participations to any person (other than a natural person
or Borrower or any of Borrower's Affiliates or Subsidiaries) (each, a
"PARTICIPANT") in all or a portion of such Lender's rights and/or obligations
under this Agreement (including all or a portion of its Commitment and/or the
Loans owing to it); provided that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) Borrower, the Administrative

                                     -120-

<PAGE>

Agent and the Lenders and Issuing Bank shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.

          Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce the Loan Documents and to approve any amendment, modification or waiver
of any provision of the Loan Documents; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in clause
(i), (ii) or (iii) of the first proviso to Section 10.02(b) that affects such
Participant. Subject to paragraph (e) of this Section, Borrower agrees that each
Participant shall be entitled to the benefits of Sections 2.12, 2.13 and 2.15
(subject to the requirements of those Sections) to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to paragraph (b)
of this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.08 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.14 as though it were a
Lender.

          (e) Limitations on Participant Rights. A Participant shall not be
entitled to receive any greater payment under Sections 2.12, 2.13 and 2.15 than
the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to
such Participant is made with Borrower's prior written consent.

          (f) Certain Pledges. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to
secure obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto. In
the case of any Lender that is a fund that invests in bank loans, such Lender
may, without the consent of Borrower or the Administrative Agent, collaterally
assign or pledge all or any portion of its rights under this Agreement,
including the Loans and Notes or any other instrument evidencing its rights as a
Lender under this Agreement, to any holder of, trustee for, or any other
representative of holders of, obligations owed or securities issued, by such
fund, as security for such obligations or securities.

          SECTION 10.05 SURVIVAL OF AGREEMENT. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the other parties hereto and shall survive the
execution and delivery of the Loan Documents and the making of any Loans and
issuance of any Letters of Credit, regardless of any investigation made by any
such other party or on its behalf and notwithstanding that the Agents, the
Issuing Bank or any Lender may have had notice or knowledge of any Default or
incorrect representation or warranty at the time any credit is extended
hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable
under this Agreement is outstanding and unpaid or any Letter of Credit is
outstanding and so long as the Commitments have not expired or terminated. The
provisions of Sections 2.12, 2.14, 2.15 and Article X shall survive and remain
in full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the payment of the
Reimbursement Obligations, the expiration or termination of the Letters of
Credit and the Commitments or the termination of this Agreement or any provision
hereof.

     SECTION 10.06 COUNTE RPARTS; INTEGRATION; EFFECTIVENESS; ELECTRONIC
EXECUTION.

          (a) Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and the other
Loan Documents, and any separate letter agreements with respect to fees payable
to the Administrative Agent, constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective when it shall have been executed
by the Administrative Agent and when the Administrative Agent shall have
received a fully executed and effective Amendment Agreement and counterparts
hereof that, when taken together, bear the signatures of each of the other
parties hereto. Borrower, the Guarantors, the Agents and the Lenders agree that
(a) all obligations under the Restated Credit Agreement executed on the First
Amendment Effectiveness Date, that is amended and restated hereby, shall
continue to exist under and be evidenced by this Agreement and the other Loan
Documents and shall constitute Obligations and (b) except as expressly stated
herein or amended, the other Loan Documents are ratified and confirmed as
remaining unmodified and in full force and effect with respect to all Secured
Obligations. Delivery of an executed counterpart of a signature page of this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

          (b) Electronic Execution of Assignments. The words "execution,"
"signed," "signature," and words of like import in any Assignment and Assumption
shall be deemed to include electronic signatures or the keeping of records in
electronic form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in
any applicable Requirement of Law, including the Federal Electronic Signatures
in Global and National Commerce Act, the New York State Electronic Signatures
and Records Act, or any other similar state laws based on the Uniform Electronic
Transactions Act.

          SECTION 10.07 SEVERABILITY. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          SECTION 10.08 RIGHT OF SETOFF. If an Event of Default shall have
occurred and be continuing, each Lender, the Issuing Bank, and each of their
respective Affiliates is hereby authorized at any time and from time to time, to
the fullest extent permitted by applicable Requirements of Law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final, in whatever currency) at any time held and other obligations (in whatever
currency) at any time owing by such Lender, the Issuing Bank or any such
Affiliate to or for the credit or the account of Borrower or any other Loan
Party against any and all of the obligations of Borrower or such Loan Party now
or hereafter existing under this Agreement or any other Loan Document to such
Lender or the Issuing Bank, irrespective of whether or not such Lender or the
Issuing Bank shall have made any demand under this Agreement or any other Loan
Document and although such obligations of Borrower or such Loan Party may be
contingent or unmatured or are owed to a branch or office of such Lender or the
Issuing Bank different from the branch or office holding such deposit or
obligated on such indebtedness. The rights of each Lender, the Issuing Bank and
their respective Affiliates under this Section are in addition to other rights
and remedies (including other rights of setoff) that such Lender, the Issuing
Bank or their respective Affiliates may

                                     -122-

<PAGE>

have. Each Lender and the Issuing Bank agrees to notify Borrower and the
Administrative Agent promptly after any such setoff and application; provided
that the failure to give such notice shall not affect the validity of such
setoff and application.

          SECTION 10.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

          (a) Governing Law. This Agreement shall be construed in accordance
with and governed by the law of the State of New York, without regard to
conflicts of law principles that would require the application of the laws of
another jurisdiction.

          (b) Submission to Jurisdiction. Each Loan Party hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to any Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State court or, to the
fullest extent permitted by applicable law, in such Federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement or
any other Loan Document shall affect any right that the Administrative Agent,
the Issuing Bank or any Lender may otherwise have to bring any action or
proceeding relating to this Agreement or any other Loan Document against any
Loan Party or its properties in the courts of any jurisdiction.

          (c) Waiver of Venue. Each Loan Party hereby irrevocably and
unconditionally waives, to the fullest extent permitted by applicable
Requirements of Law, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Agreement or any other Loan Document in any court referred to in Section
10.09(b). Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by applicable Requirements of Law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

          (d) Service of Process. Each party hereto irrevocably consents to
service of process in any action or proceeding arising out of or relating to any
Loan Document, in the manner provided for notices (other than telecopier) in
Section 10.01. Nothing in this Agreement or any other Loan Document will affect
the right of any party hereto to serve process in any other manner permitted by
applicable Requirements of Law.

          SECTION 10.10 WAIVER OF JURY TRIAL. Each Loan Party hereby waives, to
the fullest extent permitted by applicable Requirements of Law, any right it may
have to a trial by jury in any legal proceeding directly or indirectly arising
out of or relating to this Agreement, any other Loan Document or the
transactions contemplated hereby (whether based on contract, tort or any other
theory). Each party hereto (a) certifies that no representative, agent or
attorney of any other party has represented, expressly or otherwise, that such
other party would not, in the event of litigation, seek to enforce the foregoing
waiver and (b) acknowledges that it and the other parties hereto have been
induced to enter into this Agreement by, among other things, the mutual waivers
and certifications in this Section.

          SECTION 10.11 HEADINGS. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

          SECTION 10.12 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. Each
of the Administrative Agent, the Lenders and the Issuing Bank agrees to maintain
the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its Affiliates and to its and its
Affiliates' respective partners, directors, officers, employees, agents,
advisors and other representatives (it being understood that the persons to whom
such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority purporting to have jurisdiction
over it or its Affiliates (including any self-regulatory authority, such as the
National Association of Insurance Commissioners), (c) to the extent required by
applicable Requirements of Law or by any subpoena or similar legal process, (d)
to any other party hereto, (e) in connection with the exercise of any remedies
hereunder or under any other Loan Document or any action or proceeding relating
to this Agreement or any other Loan Document or the enforcement of rights
hereunder or thereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section 10.12, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
Borrower and its obligations or (iii) any rating agency for the purpose of
obtaining a credit rating applicable to any Lender, (g) with the consent of
Borrower or (h) to the extent such Information (x) becomes publicly available
other than as a result of a breach of this Section or (y) becomes available to
the Administrative Agent, any Lender, the Issuing Bank or any of their
respective Affiliates on a nonconfidential basis from a source other than
Borrower. For purposes of this Section, "INFORMATION" means all information
received from Borrower or any of its Subsidiaries relating to Borrower or any of
its Subsidiaries or any of their respective businesses, other than any such
information that is available to the Administrative Agent, any Lender or the
Issuing Bank on a nonconfidential basis prior to disclosure by Borrower or any
of its Subsidiaries; provided that, in the case of information received from
Borrower or any of its Subsidiaries after the Closing Date, such information is
clearly identified at the time of delivery as confidential. Any person required
to maintain the confidentiality of Information as provided in this Section shall
be considered to have complied with its obligation to do so if such person has
exercised the same degree of care to maintain the confidentiality of such
Information as such person would accord to its own confidential information.

          SECTION 10.13 USA PATRIOT ACT NOTICE. Each Lender that is subject to
the Act (as hereinafter defined) and the Administrative Agent (for itself and
not on behalf of any Lender) hereby notifies Borrower that pursuant to the
requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the "ACT"), it is required to obtain, verify and record
information that identifies Borrower, which information includes the name,
address and tax identification number of Borrower and other information
regarding Borrower that will allow such Lender or the Administrative Agent, as
applicable, to identify Borrower in accordance with the Act. This notice is
given in accordance with the requirements of the Act and is effective as to the
Lenders and the Administrative Agent.

          SECTION 10.14 INTEREST RATE LIMITATION. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable Requirements of Law (collectively, the "CHARGES"),
shall exceed the maximum lawful rate (the "MAXIMUM RATE") which may be
contracted for, charged, taken, received or reserved by the Lender holding such
Loan in accordance with applicable Requirements of Law, the rate of interest
payable in respect of such Loan hereunder, together with all Charges payable in
respect thereof, shall be limited to the Maximum Rate and, to the extent lawful,
the interest and Charges that would have been payable in respect of such Loan
but were not payable as a result of the operation of this Section shall be
cumulated and the interest and Charges payable to such Lender in respect of
other Loans or periods shall be increased (but not above the Maximum Rate
therefor)

                                     -124-

<PAGE>

until such cumulated amount, together with interest thereon at the Federal Funds
Effective Rate to the date of repayment, shall have been received by such
Lender.

          SECTION 10.15 LENDER ADDENDUM. Each Lender to become a party to this
Agreement on the Closing Date, the First Amendment Effectiveness Date or the
Amendment Effectiveness Date shall do so by delivering to the Administrative
Agent a Lender Addendum duly executed by such Lender, Borrower and the
Administrative Agent.

          SECTION 10.16 OBLIGATIONS ABSOLUTE. To the fullest extent permitted by
applicable Requirements of Law, all obligations of the Loan Parties hereunder
shall be absolute and unconditional irrespective of:

          (a) any bankruptcy, insolvency, reorganization, arrangement,
     readjustment, composition, liquidation or the like of any Loan Party;

          (b) any lack of validity or enforceability of any Loan Document or any
     other agreement or instrument relating thereto against any Loan Party;

          (c) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Obligations, or any other amendment or
     waiver of or any consent to any departure from any Loan Document or any
     other agreement or instrument relating thereto;

          (d) any exchange, release or non-perfection of any other Collateral,
     or any release or amendment or waiver of or consent to any departure from
     any guarantee, for all or any of the Obligations;

          (e) any exercise or non-exercise, or any waiver of any right, remedy,
     power or privilege under or in respect hereof or any Loan Document; or

          (f) any other circumstances which might otherwise constitute a defense
     available to, or a discharge of, the Loan Parties.

          SECTION 10.17 CONSENT TO TRANSACTIONS ASSOCIATED WITH THE SPECIFIED
IPO. Notwithstanding anything herein to the contrary, the parties hereto
acknowledge and consent to all transactions entered into or actions taken by the
Companies that are (a) set forth in Schedule 10.17, (b) set forth in or
contemplated by the Registration Statement as amended and publicly filed through
the date hereof, or (c) otherwise necessary or desirable in connection with the
Specified IPO and are not adverse to the Lenders in any material manner. In
addition, all Guarantees of, and Liens securing any, Obligations (i) granted by
the Loan Parties hereunder that are no longer Loan Parties under the Third
Amended and Restated Credit Agreement or (ii) the release of which is necessary
to accomplish the transactions described in the immediately preceding sentence
shall, in each case, be terminated and released by the Collateral Agent (who is
hereby authorized to do so by the Administrative Agent, the Issuing Bank and the
Lenders) immediately prior to the effectiveness of the Third Amended and
Restated Credit Agreement.
