the Registered Exchange Offer is not consummated within 240 days of the date
hereof; (iii) within thirty (30) days following the consummation of the

Purchaser that participates in the Registered Exchange Offer or acquires New
Securities pursuant to Section 2(f) hereof, such Initial Purchaser does not

that an Initial Purchaser deliver a Prospectus containing the information
required by Item 507 or 508 of Regulation S-K under the Act in connection with
sales of New Securities acquired in exchange for such Securities shall result in
such New Securities being not “freely tradeable”; and (y) the requirement that
an Exchanging Dealer deliver a Prospectus in connection with sales of New
Securities acquired in the Registered Exchange Offer in exchange for Securities
acquired as a result of market-making activities or other trading activities
shall not

requested, a Shelf Registration Statement relating to the offer and sale of the
Securities or the New Securities, as applicable, by the Holders thereof from
time to time in accordance with the methods of distribution elected by such
Holders and set forth in such Shelf Registration Statement; provided, however,
that nothing in this Section 3(b) shall require the filing of a Shelf
Registration Statement prior to the deadline for filing the Exchange Offer
Registration Statement set forth in Section 2(a) hereof; and provided, further,

Securities received by an Initial Purchaser in exchange for Securities
constituting any portion of an unsold allotment, the Company may, if permitted
by current interpretations by the Commission’s staff, file a post-effective
amendment to the Exchange Offer Registration Statement containing the
information required by Item 507 or 508 of Regulation S-K, as applicable, in
satisfaction of its obligations under this subsection with respect thereto, and
any such Exchange Offer Registration Statement, as so amended, shall be referred
to herein as, and governed by the provisions herein applicable to, a Shelf
Registration Statement.

Securities at any time during the Shelf Registration Period, unless such action
is (x) required by applicable law or otherwise undertaken by the Company in good
faith and for valid business reasons (not including avoidance of the Company’s
obligations hereunder), including the acquisition or divestiture of assets, and
(y) permitted pursuant to Section 4(k)(ii) hereof.

(iii) The Company shall cause the Shelf Registration Statement and the related
Prospectus and any amendment or supplement thereto, as of the effective date of

Shelf Registration is suspended and, upon actual receipt of any such notice,
each Holder agrees to suspend use of the Prospectus and not to sell any
Registrable Securities pursuant to the Shelf Registration until such Holder’s
receipt of copies of the supplemented or amended Prospectus provided for in

Indenture Act in a timely manner.

(o) Each Holder of Securities or New Securities to be sold pursuant to a Shelf

connection with such sale. The Company may require such Holder to furnish to the
Company such information regarding the Holder and the distribution of such
Securities as the Company may from time to time reasonably require for inclusion
in such Registration Statement, and each such Holder shall furnish reasonably
promptly to the Company any additional information required to be disclosed in
order to make the information previously disclosed to the Company by such Holder
and included in such Shelf Registration Statement not misleading. The Company
may exclude from such Shelf Registration Statement the Securities of any Holder
that unreasonably fails to furnish such information within a reasonable time
after receiving such request.

(ii) cause the Company’s officers, directors, employees, accountants and

agreements from such requesting party;

(iii) make such representations and warranties to the requesting party, in form,
substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings and covering matters including, but not limited

financial data are, or are required to be, included in the Registration
Statement), addressed to the requesting party, in customary form and covering
matters of the type customarily covered in “comfort” letters in connection with
primary underwritten offerings, or if requested by the requesting party or its
counsel in lieu of a “comfort” letter, an agreed-upon procedures letter under
Statement on Auditing Standards No. 35, covering matters reasonably requested by
the requesting party or its counsel; and

(vi) deliver such documents and certificates as may be reasonably requested by
the requesting party or its counsel, including those to evidence compliance with

The foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of this
Section shall be performed at the close of the Registered Exchange Offer and the
effective date of any post-effective amendment to the Exchange Offer
Registration Statement.

(s) If a Registered Exchange Offer is to be consummated, upon delivery of the
Securities by Holders to the Company (or to such other person as directed by the
Company) in exchange for the New Securities, the Company shall mark, or caused
to be marked, on the Securities so exchanged that such Securities are being
cancelled in exchange for the New Securities. In no event shall such Securities
be marked as paid or otherwise satisfied.

(t) The Company shall use its reasonable best efforts if the Securities have
been rated prior to the initial sale of such Securities, to confirm such ratings
will apply to the Securities or the New Securities, as the case may be, covered
by a Registration Statement at the time the Registration Statement is declared
effective.

(u) In the event that any Broker-Dealer shall underwrite any Securities or
participate as a member of an underwriting syndicate or selling group or “assist
in the distribution” (within the meaning of the NASD Rules) thereof, whether as
a Holder of such Securities or as an underwriter, a placement or sales agent or
a broker or dealer in respect thereof, or otherwise, the Company shall assist
such Broker-Dealer in complying with the NASD Rules.

(v) The Company shall use its reasonable best efforts to take all other steps

hereof and, in the event of any Shelf Registration Statement, will reimburse the

shall initially be Mayer, Brown, Rowe & Maw LLP, but which may be another
nationally recognized law firm experienced in securities matters designated by
the Majority Holders) to act as counsel for the Holders in connection therewith,
and, in the case of any Exchange Offer Registration Statement, will reimburse
the Initial Purchasers for the reasonable fees and disbursements of counsel
acting in connection therewith.

 

14

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

6. Indemnification and Contribution. (a) The Company agrees to indemnify and
hold harmless each Holder of Securities or New Securities, as the case may be,
covered by any Registration Statement, each Initial Purchaser and, with respect
to any Prospectus delivery as contemplated in Section 4(h) hereof, each
Exchanging Dealer, the directors, officers, employees, Affiliates and agents of
each such Holder, Initial Purchaser or Exchanging Dealer and each person who
controls any such Holder, Initial Purchaser or Exchanging Dealer within the
meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other U.S. federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities or actions in respect thereof arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement as originally filed or in
any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in
any amendment thereof or supplement thereto, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
preliminary Prospectus or the Prospectus, in the light of the circumstances
under which they were made) not misleading, and agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by it in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of the party claiming indemnification specifically for inclusion therein.
This indemnity agreement shall be in addition to any liability that the Company
may otherwise have.

The Company also agrees to indemnify as provided in this Section 6(a) or
contribute as provided in Section 6(d) hereof to Losses of each underwriter, if
any, of Securities or New Securities, as the case may be, registered under a
Shelf Registration Statement, their directors, officers, employees, Affiliates
or agents and each person who controls such underwriter on substantially the
same basis as that of the indemnification of the Initial Purchasers and the
selling Holders provided in this Section 6(a) and shall, if requested by any
Holder, enter into an underwriting agreement reflecting such agreement, as
provided in Section 4(p) hereof.

(b) Each Holder of securities covered by a Registration Statement (including
each Initial Purchaser that is a Holder, in such capacity) severally and not
jointly agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers and each person who controls the Company within
the meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each such Holder, but only with
reference to written information relating to such Holder furnished to the
Company by or on behalf of such Holder specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability that any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the

 

15

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

indemnifying party in writing of the commencement thereof; but the failure so to
notify the indemnifying party (i) will not relieve it from liability under
paragraph (a) or (b) above unless and to the extent it did not otherwise learn
of such action and such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or
(b) above. The indemnifying party shall be entitled to appoint counsel
(including local counsel) of the indemnifying party’s choice at the indemnifying
party’s expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel,
other than local counsel if not appointed by the indemnifying party, retained by
the indemnified party or parties except as set forth below); provided, however,
that such counsel shall be satisfactory to the indemnified party.
Notwithstanding the indemnifying party’s election to appoint counsel (including
local counsel) to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest; (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party; (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action; or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this
Section 6 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, then each applicable indemnifying party severally agrees
to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending any loss, claim, liability, damage or action)
(collectively “Losses”) to which such indemnified party may be subject in such
proportion as is appropriate to reflect the relative benefits received by such
indemnifying party, on the one hand, and such indemnified party, on the other
hand, from the Registration Statement which resulted in such Losses; provided,
however, that in no case shall any Initial Purchaser be responsible for any
amount in excess of the purchase discount or commission applicable to such
Security, or in the case of a New Security, applicable to the Security that was
exchangeable into such New Security, as set forth in the Final Memorandum, nor
shall any underwriter be responsible for any amount in excess of the
underwriting discount or commission applicable to the securities purchased by
such underwriter under the Registration Statement which resulted in such Losses.
If the allocation provided by the immediately preceding sentence is unavailable
for any reason,

 

16

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

the indemnifying party and the indemnified party shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of such indemnifying party, on the one hand, and such
indemnified party, on the other hand, in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the Initial Placement (before deducting expenses) as
set forth in the Final Memorandum. Benefits received by the Initial Purchasers
shall be deemed to be equal to the total purchase discounts and commissions as
set forth on the cover page of the Final Memorandum, and benefits received by
any other Holders shall be deemed to be equal to the value of receiving
Securities or New Securities, as applicable, registered under the Act. Benefits
received by any underwriter shall be deemed to be equal to the total
underwriting discounts and commissions, as set forth on the cover page of the
Prospectus forming a part of the Registration Statement which resulted in such
Losses. Relative fault shall be determined by reference to, among other things,
whether any untrue or any alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
provided by the indemnifying party, on the one hand, or by the indemnified
party, on the other hand, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The parties agree that it would not be just and
equitable if contribution were determined by pro rata allocation (even if the
Holders were treated as one entity for such purpose) or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 6, each person who
controls a Holder within the meaning of either the Act or the Exchange Act and
each director, officer, employee and agent of such Holder shall have the same
rights to contribution as such Holder, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, each officer and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

(e) The provisions of this Section will remain in full force and effect,
regardless of any investigation made by or on behalf of any Holder or the
Company or any of the indemnified persons referred to in this Section 6, and
will survive the sale by a Holder of securities covered by a Registration
Statement.

7. Underwritten Registrations. (a) If any of the Securities or New Securities,
as the case may be, covered by any Shelf Registration Statement are to be sold
in an underwritten offering, the Managing Underwriters shall be selected by the
Majority Holders, subject to the reasonable approval of the Company.

(b) No Holder may participate in any underwritten offering pursuant to any Shelf
Registration Statement, unless such Holder (i) agrees to sell such Holder’s
Securities or New Securities, as the case may be, on the basis reasonably
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements; and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements.

 

17

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

8. Registration Defaults. If any of the following events shall occur, then the
Company shall pay liquidated damages (the “Registration Default Damages”) to the
Holders of Securities in respect of the Securities as follows:

(a) if any Registration Statement required by this Agreement is not filed with
the Commission on or prior to the date specified for such filing in this
Agreement, then Registration Default Damages shall accrue on the Registrable
Securities at a rate of .25% per annum for the first 60 days from and including
such specified date and .50% per annum thereafter; or

(b) if any Registration Statement required by this Agreement is not declared
effective by the Commission on or prior to the date by which reasonable best
efforts are to be used to cause such effectiveness under this Agreement, then
commencing on the day after such specified date, Registration Default Damages
shall accrue on the Registrable Securities at a rate of .25% per annum for the
first 60 days from and including such specified date and .50% per annum
thereafter; or

(c) if any Registration Statement required by this Agreement has been declared
effective but ceases to be effective at any time at which it is required to be
effective under this Agreement, except as a result of the exercise by the
Company of its right to suspend use of a Shelf Registration Statement and the
released Prospectus pursuant to Section 4(k)(ii) hereof, then commencing on the
day the Registration Statement ceases to be effective, Registration Default
Damages shall accrue on the Registrable Securities at a rate of .25% per annum
for the first 60 days from and including such date on which the Registration
Statement ceases to be effective and .50% per annum thereafter;

provided, however, that (1) upon the filing of the Registration Statement (in
the case of paragraph (a) above), (2) upon the effectiveness of the Registration
Statement (in the case of paragraph (b) above), (3) upon the effectiveness of
the Registration Statement which had ceased to remain effective (in the case of
paragraph (c) above), or (4) upon the Securities or New Securities becoming
freely tradable under the Securities Act, Registration Default Damages shall
cease to accrue.

9. No Inconsistent Agreements. The Company has not entered into, and agrees not
to enter into, any agreement with respect to its securities that is inconsistent
with the rights granted to the Holders herein or that otherwise conflicts with
the provisions hereof.

10. Amendments and Waivers. The provisions of this Agreement may not be amended,
qualified, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Company has obtained the
written consent of the Majority Holders; provided that, with respect to any
matter that directly or indirectly affects the rights of any Initial Purchaser
hereunder, the Company shall obtain the written consent of each such Initial
Purchaser against which such amendment, qualification, supplement, waiver or
consent is to be effective; provided, further, that no amendment, qualification,
supplement, waiver or consent with respect to Section 8 hereof shall be
effective as against any Holder of Registered Securities unless consented to in
writing by such Holder; and provided, further, that the provisions of this
Article 10 may not be amended, qualified, modified or supplemented, and

 

18

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

waivers or consents to departures from the provisions hereof may not be given,
unless the Company has obtained the written consent of the Initial Purchasers
and each Holder. Notwithstanding the foregoing (except the foregoing provisos),
a waiver or consent to departure from the provisions hereof with respect to a
matter that relates exclusively to the rights of Holders whose Securities or New
Securities, as the case may be, are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect the rights of other
Holders may be given by the Majority Holders, determined on the basis of
Securities or New Securities, as the case may be, being sold rather than
registered under such Registration Statement.

11. Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, first-class mail, telex,
telecopier or air courier guaranteeing overnight delivery:

(a) if to a Holder, at the most current address given by such holder to the
Company in accordance with the provisions of this Section 11, which address
initially is, with respect to each Holder, the address of such Holder maintained
by the Registrar under the Indenture;

(b) if to the Representatives, initially at the address or addresses set forth
in the Purchase Agreement; and

(c) if to the Company, initially at its address set forth in the Purchase
Agreement.

All such notices and communications shall be deemed to have been duly given when
received.

The Initial Purchasers or the Company by notice to the other parties may
designate additional or different addresses for subsequent notices or
communications.

12. Remedies. Each Holder, in addition to being entitled to exercise all rights
provided to it herein, in the Indenture or in the Purchase Agreement or granted
by law, including recovery of liquidated or other damages, will be entitled to
specific performance of its rights under this Agreement. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Agreement and hereby agrees
to waive in any action for specific performance the defense that a remedy at law
would be adequate.

13. Successors. This Agreement shall inure to the benefit of and be binding upon
the parties hereto, their respective successors and assigns, including, without
the need for an express assignment or any consent by the Company thereto,
subsequent Holders of Securities and the New Securities, and the indemnified
persons referred to in Section 6 hereof. The Company hereby agrees to extend the
benefits of this Agreement to any Holder of Securities and the New Securities,
and any such Holder may specifically enforce the provisions of this Agreement as
if an original party hereto.

 

19

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

14. Counterparts. This Agreement may be signed in one or more counterparts, each
of which shall constitute an original and all of which together shall constitute
one and the same agreement.

15. Headings. The section headings used herein are for convenience only and
shall not affect the construction hereof.

16. Applicable Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York applicable to contracts made
and to be performed in the State of New York. The parties hereto each hereby
waive any right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

17. Severability. In the event that any one of more of the provisions contained
herein, or the application thereof in any circumstances, is held invalid,
illegal or unenforceable in any respect for any reason, the validity, legality
and enforceability of any such provision in every other respect and of the
remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties
shall be enforceable to the fullest extent permitted by law.

18. Securities Held by the Company, etc. Whenever the consent or approval of
Holders of a specified percentage of principal amount of Securities or New
Securities is required hereunder, Securities or New Securities, as applicable,
held by the Company or its Affiliates (other than subsequent Holders of
Securities or New Securities if such subsequent Holders are deemed to be
Affiliates solely by reason of their holdings of such Securities or New
Securities) shall not be counted in determining whether such consent or approval
was given by the Holders of such required percentage.

ANNEX A

Each broker-dealer that receives new securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new securities. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an “underwriter” within the meaning of
the Act. This prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of new
securities received in exchange for securities where such securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. The company has agreed that, starting on the expiration date
and ending on the close of business one year after the expiration date, it will
make this prospectus available to any broker-dealer for use in connection with
any such resale. See “Plan of Distribution”.

 

A-1

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

ANNEX B

Each broker-dealer that receives new securities for its own account in exchange
for securities, where such securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such new
securities. See “Plan of Distribution”.

 

B-1

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

ANNEX C

PLAN OF DISTRIBUTION

Each broker-dealer that receives new securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new securities. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new securities received in exchange for securities
where such securities were acquired as a result of market-making activities or
other trading activities. The company has agreed that, starting on the
expiration date and ending on the close of business one year after the
expiration date, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, all dealers effecting transactions in the new securities may be
required to deliver a prospectus.

The company will not receive any proceeds from any sale of new securities by
brokers-dealers. New securities received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the new securities or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such new securities. Any
broker-dealer that resales new securities that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such new securities may be deemed to be an
“underwriter” within the meaning of the Act and any profit of any such resale of
new securities and any commissions or concessions received by any such persons
may be deemed to be underwriting compensation under the Act. The Letter of
Transmittal states that by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Act.

For a period of one year after the expiration date, the company will promptly
send additional copies of this prospectus and any amendment or supplement to
this prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. The company has agreed to pay all expenses incident to the
Exchange Offer (including the expenses of one counsel for the holder of the
securities) other than commissions or concessions of any brokers or dealers and
will indemnify the holders of the securities (including any broker-dealers)
against certain liabilities, including liabilities under the Act.
