                  (a)      The Issuers shall prepare and file or cause to be
prepared and filed with the SEC no later than a date which is 90 days after the
Issue Date (the "Filing Deadline Date") a Registration Statement for an offering
to be made on a delayed or continuous basis pursuant to Rule 415 of the
Securities Act (a "Shelf Registration Statement") relating to the offer and sale
from time to time by Holders of all of the Registrable Securities (the "Initial
Shelf Registration Statement"). The Initial Shelf Registration Statement shall
be on Form S-3 or another appropriate form permitting registration of such
Registrable Securities for resale by such Holders in accordance with the methods
of distribution reasonably elected by the Holders and set forth in the Initial
Shelf Registration Statement; provided that in no event will such method(s) of
distribution take the form of an underwritten offering of the Registrable
Securities without the prior agreement of the Issuers. The Issuers shall use
reasonable efforts to cause the Initial Shelf Registration Statement to be
declared effective under the Securities Act no later than the date (the
"Effectiveness Deadline Date") that is 180 days after the Issue Date, and to
keep the Initial Shelf Registration Statement (or any Subsequent Shelf
Registration Statement) continuously effective under the Securities Act until
the expiration of the Effectiveness Period. Each Holder that became a Notice
Holder on or prior to the date ten Business Days prior to the time that the
Initial Shelf Registration

                                       4
<PAGE>

Statement became effective shall be named as a selling securityholder in the
Initial Shelf Registration Statement and the related Prospectus in such a manner
as to permit such Holder to deliver such Prospectus to purchasers of Registrable
Securities in accordance with applicable law (other than laws not generally
applicable to all such Holders). Notwithstanding the foregoing, no Holder shall
be entitled to have the Registrable Securities held by it covered by such Shelf
Registration Statement unless such Holder has provided a Notice and
Questionnaire in accordance with Section 2(d) and is in compliance with Section
4. Except as described in the Offering Memorandum, none of the Issuers'
securityholders (other than the Holders of Registrable Securities) shall have
the right to include any of the Issuers' securities in the Shelf Registration
Statement.

                  (b)      If the Initial Shelf Registration Statement or any
Subsequent Shelf Registration Statement ceases to be effective for any reason at
any time during the Effectiveness Period, the Issuers shall use reasonable
efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 30 days of such cessation
of effectiveness amend the Shelf Registration Statement in a manner reasonably
expected by the Issuers to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional Shelf Registration Statement
covering all of the securities that as of the date of such filing are
Registrable Securities (a "Subsequent Shelf Registration Statement"). If a
Subsequent Shelf Registration Statement is filed, the Issuers shall use
reasonable efforts to cause the Subsequent Shelf Registration Statement to
become effective as promptly as is reasonably practicable after such filing or,
if filed during a Deferral Period, after the expiration of such Deferral Period,
and to keep such Registration Statement (or subsequent Shelf Registration
Statement) continuously effective until the end of the Effectiveness Period.

                  (c)      The Issuers shall supplement and amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Issuers for such Shelf
Registration Statement, if required by the Securities Act or, to the extent to
which the Issuers do not reasonably object, as reasonably requested by the
Initial Purchaser or by the Trustee on behalf of the registered Holders.

                  (d)      Each Holder of Registrable Securities agrees that if
such Holder wishes to sell Registrable Securities pursuant to a Shelf
Registration Statement and related Prospectus, it will do so only in accordance
with this Section 2(d) and Section 3(i) and Section 4. Each Holder of
Registrable Securities wishing to sell Registrable Securities pursuant to a
Shelf Registration Statement and related Prospectus shall deliver a Notice and
Questionnaire to the Issuers at least five (5) Business Days prior to any
intended distribution of Registrable Securities under the Shelf Registration
Statement. From and after the date the Initial Shelf Registration Statement is
declared effective, the Issuers shall, as promptly as is reasonably practicable
after the date a Notice and Questionnaire is delivered, (i) if required by
applicable law, file with the SEC a post-effective amendment to the Shelf
Registration Statement or prepare and, if required by applicable law, file a
supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other document required
by the SEC so that the Holder delivering such Notice and Questionnaire is named
as a selling securityholder in the Shelf Registration Statement and the related
Prospectus in such a manner as to permit such Holder to deliver such Prospectus

                                       5
<PAGE>

to purchasers of the Registrable Securities in accordance with applicable law
(other than laws not generally applicable to all Holders of Registrable
Securities wishing to sell Registrable Securities pursuant to the Shelf
Registration Statement and related Prospectus) and, if the Issuers shall file a
post-effective amendment to the Shelf Registration Statement, use reasonable
efforts to cause such post-effective amendment to be declared effective under
the Securities Act as promptly as is reasonably practicable; (ii) provide such
Holder copies of any documents filed pursuant to Section 2(d)(i); and (iii)
notify such Holder as promptly as is reasonably practicable after the
effectiveness under the Securities Act of any post-effective amendment filed
pursuant to Section 2(d)(i); provided that if such Notice and Questionnaire is
delivered during a Deferral Period, the Company shall so inform the Holder
delivering such Notice and Questionnaire and shall take the actions set forth in
clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in
accordance with Section 3(i), provided further that if under applicable law the
Issuers have more than one option as to the type or manner of making any such
filing, it will make the required filing or filings in the manner or of a type
that the Issuers reasonably expect will result in the earliest availability of
the Prospectus for effecting resales of Registrable Securities. Notwithstanding
anything contained herein to the contrary, the Issuers shall be under no
obligation to name any Holder that is not a Notice Holder as a selling
securityholder in any Registration Statement or related Prospectus; provided,
however, that any Holder that becomes a Notice Holder pursuant to the provisions
of Section 2(d) of this Agreement (whether or not such Holder was a Notice
Holder at the time the Registration Statement was initially declared effective)
shall be named as a selling securityholder in the Registration Statement or
related Prospectus subject to and in accordance with the requirements of this
Section 2(d).

                  (e)      The parties hereto agree that the Holders of
Registrable Securities will suffer damages, and that it would not be feasible to
ascertain the extent of such damages with precision, if (i) the Initial Shelf
Registration Statement has not been filed on or prior to the Filing Deadline
Date, (ii) the Initial Shelf Registration Statement has not been declared
effective under the Securities Act on or prior to the Effectiveness Deadline
Date, or (iii) the aggregate duration of Deferral Periods in any period exceeds
the number of days permitted in respect of such period pursuant to Section 3(i)
hereof (each of the events of a type described in any of the foregoing clauses
(i) through (iii) is individually referred to herein as an "Event," and the
Filing Deadline Date in the case of clause (i), the Effectiveness Deadline Date
in the case of clause (ii), and the date on which the aggregate duration of
Deferral Periods in any period exceeds the number of days permitted by Section
3(i) hereof in the case of clause (iii), being referred to herein as an "Event
Date"). Events shall be deemed to continue until the "Event Termination Date,"
which shall be the following dates with respect to the respective types of
Events: the date the Initial Shelf Registration Statement is filed in the case
of an Event of the type described in clause (i), the date the Initial Shelf
Registration Statement is declared effective under the Securities Act in the
case of an Event of the type described in clause (ii), and termination of the
Deferral Period that caused the limit on the aggregate duration of Deferral
Periods in a period set forth in Section 3(i) to be exceeded in the case of the
commencement of an Event of the type described in clause (iii).

                  Accordingly, commencing on (and including) any Event Date and
ending on (but excluding) the Event Termination Date (a "Damages Accrual
Period"), the Issuers agree to pay, as liquidated damages and not as a penalty,
an amount (the "Liquidated Damages

                                       6
<PAGE>

Amount") equal to 0.25% per annum for the first 90-day period from the Event
Date, and thereafter at a rate per annum equal to 0.50% of the aggregate
principal amount of such Notes determined as of the Business Day immediately
preceding the next Damages Payment Date.

                  The Liquidated Damages Amount shall be payable on the Damages
Payment Dates to Record Holders of then outstanding Notes that are Registrable
Securities accruing, for each portion of such Damages Accrual Period beginning
on and including a Damages Payment Date (or, in respect of the first time that
the Liquidation Damages Amount is to be paid to Holders on a Damages Payment
Date as a result of the occurrence of any particular Event, from the Event Date)
and ending on but excluding the first to occur of (A) the date of the end of the
Damages Accrual Period or (B) the next Damages Payment Date; provided that any
Liquidated Damages Amount accrued with respect to any Note or portion thereof
called for redemption on a redemption date or converted into Underlying Common
Stock on a conversion date prior to the Damages Payment Date shall, in any such
event, be paid instead to the Holder who submitted such Note or portion thereof
for redemption or conversion on the applicable redemption date or conversion
date, as the case may be, on such date (or promptly following the conversion
date, in the case of conversion). Notwithstanding the foregoing, no Liquidated
Damages Amounts shall accrue as to any Registrable Security from and after the
earlier of (x) the date such security is no longer a Registrable Security and
(y) expiration of the Effectiveness Period.

                  The rate of accrual of the Liquidated Damages Amount with
respect to any period shall not exceed the rate provided for in this Section
2(e) notwithstanding the occurrence of multiple concurrent Events. Following the
cure of all Events requiring the payment by the Issuers of Liquidated Damages
Amounts to the Holders of Registrable Securities pursuant to this Section 2(e),
the accrual of Liquidated Damages Amounts will cease (without in any way
limiting the effect of any subsequent Event requiring the payment of the
Liquidated Damages Amount by the Issuers).

                  The Trustee, subject to the applicable provisions of the
Indenture, shall be entitled, on behalf of Holders of Notes or Underlying Common
Stock, to seek any available remedy for the enforcement of this Agreement,
including for the payment of any Liquidated Damages Amount. Notwithstanding the
foregoing, the parties agree that the sole monetary damages payable for a
violation of the terms of this Agreement with respect to which liquidated
damages are expressly provided shall be such liquidated damages. Nothing shall
preclude a Notice Holder or Holder of Registrable Securities from pursuing or
obtaining specific performance or other equitable relief with respect to this
Agreement.

                  The parties hereto agree that the liquidated damages provided
for in this Section 2(e) constitute a reasonable estimate of the damages that
may be incurred by Holders of Registrable Securities by reason of the failure of
the Shelf Registration Statement to be filed or declared effective or available
for effecting resales of Registrable Securities in accordance with the
provisions hereof.

                                       7

                  SECTION 3. Registration Procedures. In connection with the
registration obligations of the Issuers under Section 2 hereof, during the
Effectiveness Period the Issuers shall:

                  (a)      Before filing any Registration Statement or
Prospectus or any amendments or supplements (other than supplements that do
nothing more substantive than name one or more Notice Holders as selling
securityholders) thereto with the SEC, furnish to the Initial Purchaser copies
of all such documents proposed to be filed and use reasonable efforts to reflect
in each such document when so filed with the SEC such comments as the Initial
Purchaser reasonably shall propose within three (3) Business Days of the
delivery of such copies to the Initial Purchaser.

                  (b)      Subject to Section 3(i), prepare and file with the
SEC such amendments and post-effective amendments to each Registration Statement
as may be necessary to keep such Registration Statement continuously effective
for the applicable period specified in Section 2(a); cause the related
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 (or any similar provisions then in
force) under the Securities Act; and use reasonable efforts to comply with the
provisions of the Securities Act applicable to it with respect to the
disposition of all securities covered by such Registration Statement during the
Effectiveness Period in accordance with the intended methods of disposition by
the sellers thereof set forth in such Registration Statement as so amended or
such Prospectus as so supplemented.

                  (c)      As promptly as reasonably practicable give notice to
the Notice Holders and the Initial Purchaser (i) when any Prospectus, Prospectus
supplement, Registration Statement or post-effective amendment to a Registration
Statement has been filed with the SEC and, with respect to a Registration
Statement or any post-effective amendment, when the same has been declared
effective (provided, however, that the Issuers shall not be required by this
clause (i) to notify (A) the Initial Purchaser of the filing of a Prospectus
supplement that does nothing more substantive than name one or more Notice
Holders as selling securityholders or (B) any Notice Holder of the filing of a
Prospectus supplement that does nothing more substantive than name one or more
other Notice Holders as selling securityholders), (ii) of any request, following
the effectiveness of the Initial Shelf Registration Statement under the
Securities Act, by the SEC or any other federal or state governmental authority
for amendments or supplements to any Registration Statement or related
Prospectus or for additional information, (iii) of the issuance by the SEC or
any other federal or state governmental authority of any stop order or
injunction suspending or enjoining the use of any Prospectus or the
effectiveness of any Registration Statement or the initiation or threatening of
any proceedings for that purpose, (iv) of the receipt by the Issuers of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of (but not the nature of or details concerning)
a Material Event (provided, however, that no notice by the Issuers shall be
required pursuant to this clause (v) in the event that the Issuers either
promptly file a Prospectus supplement to update the Prospectus or a Current
Report on Form 8-K or other appropriate Exchange Act report that is incorporated
by reference into the Registration Statement, which, in either case, contains
the requisite information with respect

                                       8
<PAGE>

to such Material Event that results in such Registration Statement no longer
containing any untrue statement of material fact or omitting to state a material
fact necessary to make the statements contained therein not misleading) and (vi)
of the determination by the Issuers that a post-effective amendment to a
Registration Statement will be filed with the SEC, which notice may, at the
discretion of the Issuers (or as required pursuant to Section 3(i)), state that
it constitutes a Deferral Notice, in which event the provisions of Section 3(i)
shall apply.

                  (d)      Use reasonable efforts to obtain the withdrawal of
any order suspending the effectiveness of a Registration Statement or the
lifting of any suspension of the qualification (or exemption from qualification)
of any of the Registrable Securities for sale in any jurisdiction in which they
have been qualified for sale, in either case at the earliest possible moment or,
if any such order or suspension is made effective during any Deferral Period, at
the earliest possible moment after the expiration of such Deferral Period.

                  (e)      If reasonably requested by the Initial Purchaser or
any Notice Holder, as promptly as reasonably practicable incorporate in a
Prospectus supplement or post-effective amendment to a Registration Statement
such information as the Initial Purchaser or such Notice Holder shall have so
requested to the extent the Issuers do not reasonably object thereto.

                  (f)      As promptly as reasonably practicable after the
filing of such documents with the SEC, furnish to each Notice Holder and the
Initial Purchaser, upon their request and without charge, at least one conformed
copy of the Registration Statement and any amendment thereto, including
financial statements, but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits (unless
requested in writing to the Issuers by such Notice Holder or the Initial
Purchaser, as the case may be).

                  (g)      During the Effectiveness Period, deliver to each
Notice Holder in connection with any sale of Registrable Securities pursuant to
a Registration Statement, without charge, as many copies of the Prospectus or
Prospectuses relating to such Registrable Securities (including each preliminary
prospectus) and any amendment or supplement thereto as such Notice Holder may
reasonably request; and the Issuers hereby consent (except during such periods
that a Deferral Notice is outstanding and has not been revoked) to the use of
such Prospectus or each amendment or supplement thereto by each Notice Holder in
connection with any offering and sale of the Registrable Securities covered by
such Prospectus or any amendment or supplement thereto in the manner set forth
therein.

                  (h)      Subject to Section 3(i), prior to any public offering
of the Registrable Securities pursuant to the Shelf Registration Statement, use
reasonable efforts to register or qualify or cooperate with the Notice Holders
in connection with the registration or qualification (or exemption from such
registration or qualification) of such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions within the United
States as any Notice Holder reasonably requests in writing (which request may be
included in the Notice and Questionnaire), it being agreed that no such
registration or qualification will be made unless so requested; prior to any
public offering of the Registrable Securities pursuant to the Shelf Registration
Statement, use reasonable efforts to keep each

                                       9
<PAGE>

such registration or qualification (or exemption therefrom) effective during the
Effectiveness Period in connection with such Notice Holder's offer and sale of
Registrable Securities pursuant to such registration or qualification (or
exemption therefrom) and do any and all other acts or things reasonably
necessary to enable the disposition in such jurisdictions of such Registrable
Securities in the manner set forth in the relevant Registration Statement and
the related Prospectus; provided that the Issuers will not be required to (i)
qualify as a foreign corporation or as a dealer in securities in any
jurisdiction where it is not otherwise qualified or (ii) take any action that
would subject it to general service of process in suits or to taxation in any
such jurisdiction where it is not then so subject.

                  (i)      Upon (A) the issuance by the SEC of a stop order
suspending the effectiveness of the Shelf Registration Statement or the
initiation of proceedings with respect to the Shelf Registration Statement under
Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or
the existence of any fact (a "Material Event") as a result of which any
Registration Statement shall contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, or any Prospectus shall contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading (including, in
any such case, as a result of the non-availability of financial statements), or
(C) the occurrence or existence of any pending corporate development that, in
the discretion of the Issuers, makes it appropriate to suspend the availability
of the Shelf Registration Statement and the related Prospectus, (i) in the case
of clause (B) above, subject to the next sentence, as promptly as practicable
prepare and file a post-effective amendment to such Registration Statement or a
supplement to the related Prospectus or any document incorporated therein by
reference or file any other required document that would be incorporated by
reference into such Registration Statement and Prospectus so that such
Registration Statement does not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, and such Prospectus does not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, as
thereafter delivered to the purchasers of the Registrable Securities being sold
thereunder, and, in the case of a post-effective amendment to a Registration
Statement, subject to the next sentence, use reasonable efforts to cause it to
be declared effective as promptly as is reasonably practicable, and (ii) give
notice to the Notice Holders that the availability of the Shelf Registration
Statement is suspended (a "Deferral Notice") and, upon receipt of any Deferral
Notice, each Notice Holder agrees not to sell any Registrable Securities
pursuant to the Registration Statement until such Notice Holder's receipt of
copies of the supplemented or amended Prospectus provided for in clause (i)
above, or until it is advised in writing by the Issuers that the Prospectus may
be used, and has received copies of any additional or supplemental filings that
are incorporated or deemed incorporated by reference in such Prospectus. The
Issuers will use reasonable efforts to ensure that the use of the Prospectus may
be resumed (x) in the case of clause (A) above, as promptly as is practicable,
and (y) in the case of clauses (B) and (C) above, as soon as, in the sole
judgment of the Issuers, public disclosure of such Material Event or pending
corporate development would not be prejudicial to or contrary to the interests
of the Issuers or, if necessary to avoid

                                       10
<PAGE>

unreasonable burden or expense, as soon as reasonably practicable thereafter. So
long as the period during which the availability of the Registration Statement
and any Prospectus is suspended (the "Deferral Period") does not exceed
forty-five (45) days during any three (3) month period or one hundred and twenty
(120) days during any twelve (12) month period, the Issuers shall not incur any
obligation to pay liquidated damages pursuant to Section 2(e).

                  (j)      In connection with a disposition of Registrable
Securities pursuant to a Registration Statement, make reasonably available for
inspection at reasonable times by one or more representatives of the Notice
Holders, and any broker-dealer, attorneys or accountants retained by such Notice
Holders, all financial and other records, pertinent corporate documents and
properties of the Issuers as shall be reasonably necessary to enable them to
exercise any applicable due diligence responsibilities as are customary, and
cause the Issuers' officers, directors and employees to supply all information
reasonably requested by any such representative or representatives of the Notice
Holders, broker-dealers, attorneys or accountants in connection with the Self
Registration Statement after the filing thereof and before its effectiveness;
provided, however, that such persons shall first agree in writing with the
Issuers that any information that is reasonably designated by the Issuers in
writing as confidential at the time of delivery of such information shall be
kept confidential by such persons and shall be used solely for the purposes of
exercising rights under this Agreement; and provided further that, if the
foregoing inspection and information gathering would otherwise disrupt the
Issuers' conduct of business, such inspection and information gathering shall,
to the greatest extent possible, be coordinated on behalf of the Notice Holders
and the other parties entitled thereto by one counsel designated by and on
behalf of Notice Holders and the other parties and reasonably acceptable to the
Issuers.

                  (k)      Comply with all applicable rules and regulations of
the SEC and make generally available to its security holders earning statements
(which need not be audited) satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder (or any similar rule promulgated under
the Securities Act) no later than the time period prescribed by the SEC for
filing a Form 10-Q after the end of any 12-month period (or the time period
prescribed by the SEC for filing a Form 10-K after the end of any 12-month
period if such period is a fiscal year) commencing on the first day of the first
fiscal quarter of the Issuers commencing after the effective date of a
Registration Statement, which statements shall cover said 12-month periods.

                  (l)      Cooperate with each Notice Holder to facilitate the
timely preparation and delivery of certificates representing Registrable
Securities sold pursuant to a Registration Statement, and cause such Registrable
Securities to be in such denominations as are permitted by the Indenture and
registered in such names as such Notice Holder may request in writing at least
two Business Days prior to any sale of such Registrable Securities.

                  (m)      Provide a CUSIP number for all Registrable Securities
covered by each Registration Statement not later than the effective date of such
Registration Statement and provide the Trustee for the Notes and the transfer
agent for the Common Stock with certificates for the Registrable Securities that
are in a form eligible for deposit with The Depository Trust Company.

                                       11
<PAGE>

                  (n)      Make reasonable effort to provide such information as
is required for any filings required to be made with the National Association of
Securities Dealers, Inc.

                  (o)      Upon (i) the filing of the Initial Shelf Registration
Statement and (ii) the effectiveness of the Initial Shelf Registration
Statement, announce the same, in each case by release to Businesswire, Reuters
Economic Services, Bloomberg Business News or any other means of dissemination
reasonably expected to make such information known publicly.

                  (p)      Take all actions necessary, or reasonably requested
by the holders of a majority of the Registrable Securities being sold, in order
to expedite or facilitate disposition of such Registrable Securities; provided
that in no event will such actions take the form of an underwritten offering of
the Registrable Securities without the prior agreement of the Issuers.

                  (q)      Cause the Indenture to be qualified under the TIA not
later than the effective date of any Registration Statement; and in connection
therewith, cooperate with the Trustee to effect such changes to the Indenture as
may be required for the Indenture to be so qualified in accordance with the
terms of the TIA and execute, and use reasonable efforts to cause the Trustee to
execute, all documents as may be required to effect such changes, and all other
forms and documents required to be filed with the SEC to enable the Indenture to
be so qualified in a timely manner.

                  SECTION 4. Holder's Obligations. Each Holder agrees, by
acquisition of the Registrable Securities, that no Holder of Registrable
Securities shall be entitled to sell any of such Registrable Securities pursuant
to a Registration Statement or to receive a Prospectus relating thereto, unless
such Holder has furnished the Issuers with a Notice and Questionnaire as
required pursuant to Section 2(d) hereof (including the information required to
be included in such Notice and Questionnaire) and the information set forth in
the next sentence. Each Notice Holder agrees promptly to furnish to the Issuers
all information required to be disclosed in order to make the information
previously furnished to the Issuers by such Notice Holder not misleading, any
other information regarding such Notice Holder and the distribution of such
Registrable Securities as may be required to be disclosed in the Registration
Statement under applicable law or pursuant to SEC comments and any information
otherwise required by the Issuers to comply with applicable law or regulations.
Each Holder further agrees, following termination of the Effectiveness Period,
to notify the Issuers, within ten Business Days of a request, of the amount of
Registrable Securities sold pursuant to the Registration Statement and, in the
absence of a response, the Issuers may assume that all of the Holder's
Registrable Securities were so sold.

                  SECTION 5. Registration Expenses. The Issuers shall bear all
fees and expenses incurred in connection with the performance by the Company of
its obligations under Sections 2 and 3 of this Agreement whether or not any of
the Registration Statements are declared effective. Such fees and expenses shall
include, without limitation, (i) all registration and filing fees (including,
without limitation, fees and expenses (x) with respect to filings required to be
made with the National Association of Securities Dealers, Inc. and (y) of
compliance with federal and state securities or Blue Sky laws to the extent such
filings or compliance are required pursuant to this Agreement (including,
without limitation,

                                       12
<PAGE>

reasonable fees and disbursements of the counsel specified in the next sentence
in connection with Blue Sky qualifications of the Registrable Securities under
the laws of such jurisdictions as the Notice Holders of a majority of the
Registrable Securities being sold pursuant to a Registration Statement may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities in a form eligible for deposit
with The Depository Trust Company), (iii) duplication expenses relating to
copies of any Registration Statement or Prospectus delivered to any Holders
hereunder, (iv) fees and disbursements of counsel for the Issuers in connection
with the Shelf Registration Statement, and (v) reasonable fees and disbursements
of the Trustee and its counsel and of the registrar and transfer agent for the
Common Stock. In addition, the Issuers shall bear or reimburse the Notice
Holders for the fees and disbursements of one firm of legal counsel retained by
the Holders, which shall, upon the written consent of the Initial Purchaser
(which shall not be unreasonably withheld), be another nationally recognized law
firm experienced in securities law matters designated by the Issuers. In
addition, the Issuers shall pay the internal expenses of the Issuers (including,
without limitation, all salaries and expenses of officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange on which the same securities of the
Issuers are then listed and the fees and expenses of any person, including
special experts, retained by the Issuers. Each Notice Holder shall pay all
underwriting discounts, commissions and transfer taxes, if any, relating to the
sale or disposition of such Notice Holder's Registrable Securities pursuant to
the Shelf Registration Statement.

                  SECTION 6. Indemnification; Contribution.

                  (a)      The Issuers agree, jointly and severally, to
indemnify and hold harmless the Initial Purchaser and each holder of Registrable
Securities and each person who controls the Initial Purchaser or any holder of
Registrable Securities within the meaning of either Section 15 of the Securities
Act or Section 20 of 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 Securities Act, the Exchange Act, or other 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 or in any amendment
thereof, or arise out of or are based upon the omission or alleged omission to
state therein a material fact necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading or
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact included in any preliminary prospectus or the Prospectus or
in any amendment thereof or supplement thereto, or the omission or alleged
omission therefrom of a material fact required to be stated therein or necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, and, in each case, agrees to reimburse
each such indemnified party for any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that (i) 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

                                       13
<PAGE>

in conformity with, written information relating to the Initial Purchaser
furnished to the Company by or the Initial Purchaser specifically for use in
connection with the preparation of the Registration Statement or any amendment
thereof, or any preliminary prospectus or the Prospectus or in any amendment
thereof or supplement thereto, (ii) the foregoing indemnity agreement, with
respect to any preliminary prospectus, shall not inure to the benefit of any
holder of Registrable Securities (or any person controlling such holder of
Registrable Securities) as to whom it shall be established did not send or
deliver to the person asserting any such loss, claim, damage or liability and
who purchased Securities which are the subject thereof a copy of the Prospectus
as amended or supplemented (exclusive of material incorporated by reference) at
or prior to the written confirmation of the sale of such Securities in any case
where such delivery is required by the Securities Act, and the untrue statement
or omission of a material fact contained in such preliminary prospectus was
corrected in the Prospectus as amended or supplemented and the Company had
previously furnished copies thereof to the Initial Purchaser, and (iii) the
Company will not be liable for any loss, liability or expense of any settlement
or compromise of, or consent to entry of judgment with respect to, any pending
or threatened litigation or any pending or threatened governmental agency
investigation or proceeding if such settlement or compromise of or consent to
entry of judgment with respect thereto is effected without the prior written
consent of the Company, except to the extent that such consent is not required
pursuant to Section 6(d) hereof; and provided further that this indemnity
agreement shall not apply to any such loss, claim, damage or liability arising
from an offer or sale of Registrable Securities occurring during a Deferral
Period, if a Deferral Notice was given to such Notice Holder in accordance with
Section 8(c). This indemnity agreement will be in addition to any liability that
the Company may otherwise have.

                  (b)      In connection with any Registration Statement in
which a Holder, including, without limitation, the Initial Purchaser, of
Registrable Securities is participating, is furnishing information relating to
such Holder of Registrable Securities to the Issuers in writing expressly for
use in such Registration Statement, any preliminary prospectus, the Prospectus
or any amendments or supplements thereto, the Holders of such Registrable
Securities agree, severally and not jointly, to indemnify and hold harmless the
Initial Purchaser and each person, if any, who controls the Initial Purchaser
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act and the Issuers, and each person, if any, who controls the
Issuers within the meaning of either such Section, against any and all loss,
liability, claim, damage and expense described in the indemnity contained in
subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto) in reliance upon and
in conformity with written information furnished to the Issuers by or on behalf
of such holder of Registrable Securities (which also acknowledges the indemnity
provisions herein) or any person, if any, who controls any such holder of
Registrable Securities specifically for use in the Registration Statement (or
any amendment thereto) or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto). This indemnity agreement will be in addition
to any liability that any Holder of such Registrable Securities may otherwise
have.

                                       14
<PAGE>

                  The Initial Purchaser agrees to indemnify and hold harmless
the Issuers or any Holders of Registrable Securities and each person who
controls an Issuer or any Holders of Registrable Securities, as the case may be,
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act, against any and all losses, claims, damages, liabilities and
expenses described in the indemnity contained in Section 6(a), but only with
respect to untrue statements or alleged untrue statements or omissions or
alleged omissions made in the Registration Statement (or any amendment thereto)
or any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information relating to
the Initial Purchaser furnished to the Company by the Initial Purchaser
specifically for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus or the Prospectus (or any amendment or supplement
thereto). This indemnity agreement will be in addition to any liability that the
Initial Purchaser 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 indemnifying party or parties in writing
of the commencement thereof; but the omission so to notify the indemnifying
party or parties will not relieve it from any liability which it may have to any
indemnified party otherwise than under this Section 6. In case any such action
is brought against any indemnified party and it notifies the indemnifying party
or parties of the commencement thereof, the indemnifying party or parties will
be entitled to participate therein, and to the extent that it may elect, by
written notice delivered to such indemnified party promptly after receiving the
aforesaid notice from such indemnified party, to assume the defense thereof,
with counsel satisfactory to such indemnified party; provided, however, that if,
in the reasonable judgment of such indemnified party, a conflict of interest
exists where it is advisable for such indemnified party to be represented by
separate counsel, the indemnified party shall have the right to employ separate
counsel in any such action, in which event the fees and expenses of such
separate counsel shall be borne by the indemnifying party or parties. Upon
receipt of notice from the indemnifying party or parties to such indemnified
party of the election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party or parties will not be
liable to such indemnified party under this Section 6 for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof unless (i) the indemnified party shall have employed separate
counsel in accordance with the proviso to the next preceding sentence (it being
understood, however, that the indemnifying party or parties shall not be liable
for the expenses of more than one such separate counsel representing the
indemnified parties under subparagraph (a) of this Section 6 who are parties to
such action), (ii) the indemnifying party or parties shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action or (iii) the
indemnifying party or parties have authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party or parties; and
except that, if clause (i) or (iii) is applicable, such liability shall be only
in respect of the counsel referred to in such clause (i) or (iii). It is
understood that all such fees and expenses of counsel for the indemnified party
for which the indemnifying party is liable shall be reimbursed as they are
incurred. No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be

                                       15
<PAGE>

unreasonably withheld), effect any settlement or compromise of, or consent to
entry of judgment with respect to, any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement or compromise of, or consent to entry of judgment with respect
thereto includes an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such proceeding and does not
include a statement as to or an admission of fault, culpability or failure to
act by or on behalf of any indemnified party.

                  (d)      If at any time an indemnified party shall have
requested an indemnifying party to reimburse the indemnified party for fees and
expenses of counsel payable pursuant to this Section 6, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid notice of request, (ii) such indemnifying party shall have received
notice of the terms of such settlement at least 30 days prior to such settlement
being entered into, and (iii) such indemnifying party shall not have reimbursed
such indemnified party in accordance with such request prior to the date of such
settlement.

                  (e)      If the indemnification provided for in paragraph (a)
or (b) of this Section 6 is for any reason unavailable to or insufficient to
hold harmless an indemnified party in respect of any losses, liabilities,
claims, damages or expenses referred to therein, then each indemnifying party
shall contribute to the aggregate amount of such losses, liabilities, claims,
damages and expenses incurred by such indemnified party, (i) in such proportion
as is appropriate to reflect the relative fault of the indemnifying party or
parties on the one hand and of the indemnified party on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations. The relative fault of the Issuers on the one hand and
the Holders of Registrable Securities or the Initial Purchaser on the other hand
shall be determined by reference to, among other things, whether any such untrue
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by the Company or by
the Holder of Registrable Securities or the Initial Purchaser and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Issuers and the Initial Purchaser agree
that it would not be just and equitable if contribution pursuant to this Section
were determined by pro rata allocation (even if the Initial Purchaser and the
Holders of Registrable Securities were treated as one entity for such purpose)
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section.

                  (f)      The aggregate amount of losses, liabilities, claims,
damages and expenses incurred by an indemnified party and referred to above in
this Section shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in investigating, preparing or defending
against any such action or claim. Notwithstanding the provisions of this
Section, no Holder of Registrable Securities nor the Initial Purchaser shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by such Holder of Registrable
Securities or by the

                                       16
<PAGE>

Initial Purchaser, as the case may be, exceeds the amount of any damages that
such Holder of Registrable Securities or the Initial Purchaser has otherwise
been required to pay by reason of any such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section, each person, if any, who
controls the Initial Purchaser or any Holder of Registrable Securities within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act shall have the same rights to contribution as the Initial Purchaser or such
Holder, and each director of the Issuers, each officer of the Issuers, and each
person, if any, who controls an Issuer within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Issuers.

                  SECTION 7. Information Requirements. The Issuers covenant
that, if at any time before the end of the Effectiveness Period the Issuers are
not subject to the reporting requirements of the Exchange Act, they will
cooperate with any Holder of Registrable Securities and take such further
reasonable action as any Holder of Registrable Securities may reasonably request
in writing (including, without limitation, making such reasonable
representations as any such Holder may reasonably request), all to the extent
required from time to time to enable such Holder to sell Registrable Securities
without registration under the Securities Act within the limitations of Rule 144
and Rule 144A under the Securities Act and customarily taken in connection with
sales pursuant to such exemptions. Upon the written request of any Holder of
Registrable Securities, the Issuers shall deliver to such Holder a written
statement as to whether it has complied with such filing requirements, unless
such a statement has been included in the Issuers' most recent report required
to be filed and filed pursuant to Section 13 or Section 15(d) of the Exchange
Act. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Issuers to register any of its securities under any section of the
Exchange Act.

                  SECTION 8. Miscellaneous

                  (a)      No Conflicting Agreements. The Issuers are not, as of
the date hereof, a party to, nor shall it, on or after the date of this
Agreement, enter into, any agreement with respect to the Issuers' securities
that conflicts in any material respect with the rights granted to the Holders of
Registrable Securities in this Agreement. The Issuers represent and warrant that
the rights granted to the Holders of Registrable Securities hereunder do not
conflict with the rights granted to the holders of the Issuers' securities under
any other agreements.

                  (b)      Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Issuers have obtained the written
consent of Holders of a majority of the then outstanding Underlying Common Stock
constituting Registrable Securities (with Holders of Notes, for purposes of this
Section, of the number of outstanding shares of Underlying Common Stock into
which such Notes would be convertible or exchangeable as of the date on which
such consent is requested). Notwithstanding the foregoing, a waiver or consent
to depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders of

                                       17
<PAGE>

Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders of Registrable Securities may be given by Holders of at
least a majority of the Registrable Securities being sold by such Holders
pursuant to such Registration Statement; provided that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with
the provisions of the immediately preceding sentence. Each Holder of Registrable
Securities outstanding at the time of any such amendment, modification,
supplement, waiver or consent or thereafter shall be bound by any such
amendment, modification, supplement, waiver or consent effected pursuant to this
Section 8(b), whether or not any notice, writing or marking indicating such
amendment, modification, supplement, waiver or consent appears on the
Registrable Securities or is delivered to such Holder.

                  (c)      Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand delivery,
by telecopier, by courier guaranteeing overnight delivery or by first-class
mail, return receipt requested, and shall be deemed given (i) when made, if made
by hand delivery, (ii) upon confirmation, if made by telecopier, (iii) one (1)
Business Day after being deposited with such courier, if made by overnight
courier, or (iv) on the date indicated on the notice of receipt, if made by
first-class mail, to the parties as follows:

                  if to a Holder of Registrable Securities that is not a Notice
Holder, at the address for such Holder then appearing in the Registrar (as
defined in the Indenture);

                  if to a Notice Holder, at the most current address given by
such Holder to the Company in a Notice and Questionnaire or any amendment
thereto;

                  if to the Issuers, to:

or to such other address as such person may have furnished to the other persons
identified in this Section 8(c) in writing in accordance herewith.

                  (d)      Approval of Holders. Whenever the consent or approval
of Holders of a specified percentage of Registrable Securities is required
hereunder, Registrable Securities held by the Issuers or their Affiliates (other
than the Initial Purchaser or subsequent Holders of Registrable Securities if
such subsequent Holders are deemed to be such affiliates solely by reason of
their holdings of such Registrable Securities) shall not be counted in
determining whether such consent or approval was given by the Holders of such
required percentage.

                  (e)      Successors and Assigns. This Agreement shall inure to
the benefit of and be binding upon the successors and assigns of each of the
parties hereto and, without limitation of the foregoing and without requiring an
express assignment, subsequent Holders of Registrable Securities; provided,
however, that (i) this Agreement shall not inure to the benefit of or be binding
upon a successor or assign of a Holder unless and to the extent such successor
or assign acquired Registrable Securities from such Holder and (ii) nothing
contained herein shall be deemed to permit any assignment, transfer or other
disposition of Registrable Securities in violation of the terms of the Purchase
Agreement or the Indenture. If any transferee of any Holder shall acquire
Registrable Securities, in any manner, whether by operation of law or otherwise,
such Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities such person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement applicable to such Holder.

                  (f)      Counterparts. This Agreement may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each
of which when so executed shall be deemed to be original and all of which taken
together shall constitute one and the same agreement.

                  (g)      Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (h)      Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

                  (i)      Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated thereby, and the parties hereto
shall use their best efforts to find and employ an alternative means to achieve
the same or substantially the same result as that contemplated by such term,
provision, covenant or restriction, it being intended that all of the rights and
privileges of the parties hereto shall be enforceable to the fullest extent
permitted by law.

                  (j)      Entire Agreement. This Agreement is intended by the
parties hereto as a final expression of their agreement and is intended to be a
complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein and the
registration rights granted by the Issuers with respect to the Registrable
Securities. Except as provided in the Purchase Agreement, there are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein, with respect to the registration rights granted by the
Issuers with respect to the Registrable Securities. This Agreement supersedes
all prior agreements and undertakings among the parties hereto with respect to
such registration rights.

                  (k)      Termination. This Agreement and the obligations of
the parties hereunder shall terminate upon the end of the Effectiveness Period,
except for any liabilities or obligations under Section 4, 5 or 6 hereof and the
obligations to make payments of and provide for liquidated damages under Section
2(e) hereof to the extent such damages accrue prior to the end of the
Effectiveness Period, each of which shall remain in effect in accordance with
its terms.

         rights, warrants or options or distribution in respect of which the
         Average Sale Price is being calculated, or

                  (ii)     the period (x) commencing on the date next succeeding
         the first public announcement of (a) the issuance of rights, warrants
         or options or (b) the distribution, in each case, in respect of which
         the Average Sale Price is being calculated and (y) proceeding through
         the last full trading day prior to the Time of Determination with

         of which the Average Sale Price is being calculated (excluding days
         within such period, if any, which are not trading days), or

                  (iii)    the period, if any, (x) commencing on the date next

         issuance of rights, warrants or options or (b) distribution, in each
         case, for which an adjustment is required by the provisions of Sections
         10.06(c), 10.07 or 10.08 and (y) proceeding through the last full

                  SECTION 1.03      Incorporation by Reference of Trust

following TIA terms used in this Indenture have the following meanings:

                  "Commission" means the SEC.

                  All other TIA terms used in this Indenture that are defined by
the TIA, defined by TIA reference to another statute or defined by SEC rule have
the meanings assigned to them by such definitions.

                  SECTION 1.04      Rules of Construction. Unless the context
otherwise requires:

                  (1)      a defined term has the meaning assigned to it;

                  (2)      an accounting term not otherwise defined has the
         meaning assigned to it in accordance with United States generally
         accepted accounting principles as in effect from time to time;

                  (3)      "or" is not exclusive;

<PAGE>

                  (4)      "including" means including, without limitation; and

                  (5)      words in the singular include the plural, and words
         in the plural include the singular.

                  SECTION 1.05      Acts of Holders.

                  (a)      Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders may be embodied in and evidenced by one or more instruments
(which may take the form of an electronic writing or messaging or otherwise be
in accordance with customary procedures of the Depositary or the Trustee) of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing (which may be in electronic form); and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, when it is hereby
expressly required, to the Company. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent
(either of which may be in electronic form) shall be sufficient for any purpose
of this Indenture and conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Section.

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

                  (c)      The ownership of Securities shall be proved by the
register maintained by the Registrar.

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

                  (e)      If the Company shall solicit from the Holders any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company shall have no
obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the outstanding Securities shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless taken on or prior to the applicable
Expiration Date (as defined below) by Holders of the requisite amount of
outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite amount of outstanding Securities on the date such action is
taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities in the manner set forth in
Section 13.02.

                  With respect to any record date set pursuant to this Section
1.05, the Company may designate any date as the "Expiration Date" and from time
to time may change the Expiration Date to any earlier or later day; provided
that no such change shall be effective unless notice of the proposed new
Expiration Date is given to the Trustee, and to each Holder in the manner set
forth in Section 13.02 on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date pursuant to
this Section, the Company shall be deemed to have initially designated the 180th
day after such record date as the Expiration Date with respect thereto, subject
to its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date.

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

Trustee's certificate of authentication shall be substantially in the form of

a form acceptable to the Company). The Company shall provide any such notations,
legends or endorsements to the Trustee in writing. Each Security shall be dated

Global Securities will not be entitled to receive physical delivery of
Non-Global Securities in certificated form and must exercise any rights in
respect of their interests, including any right to convert or require purchase
of their interests in the Securities, in accordance with the Applicable
Procedures. Each Global Security shall represent such of the outstanding
Securities as shall be specified therein and each shall provide that it shall
represent the aggregate principal amount of outstanding Securities from time to
time endorsed thereon and that the aggregate principal amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, redemptions, transfers, and conversions.

                  Any adjustment of the aggregate principal amount of a Global
Security to reflect the amount of any increase or decrease in the principal
amount of outstanding Securities represented thereby shall be made by the
Trustee in accordance with instructions given by the Holder thereof as required
by Section 2.12 hereof and shall be made on the records of the Trustee and the
Depositary.

                  (c)      Book-Entry Provisions. This Section 2.01(c) shall
apply only to Global Securities deposited with or on behalf of the Depositary.

                  THE PROHIBITED TRANSACTION RESTRICTIONS OF ERISA AND THE CODE
                  OR ANY PROVISIONS OF STATE OR FEDERAL LAWS OR REGULATIONS THAT
                  ARE SUBSTANTIALLY SIMILAR TO THE FOREGOING PROVISIONS OF ERISA
                  AND THE CODE, AS APPLICABLE, PURSUANT TO ONE OR MORE
                  PROHIBITED TRANSACTION STATUTORY OR ADMINISTRATIVE
                  EXEMPTIONS."

                  SECTION 2.02      Execution and Authentication. The Securities
shall be executed on behalf of the Company by any Officer. The signature of the
Officer on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of an
individual who was at the time of the execution of the Securities the proper
Officer of the Company shall bind the Company, notwithstanding that such
individual has ceased to hold such office prior to the authentication and
delivery of such Securities or did not hold such office at the date of
authentication of such Securities.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory of the Trustee and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder.

                  The Trustee shall authenticate and deliver Securities for
original issue in an aggregate principal amount of up to $300,000,000.00 upon a
Company Order without any further action by the Company, provided that, if the
Company sells any Securities pursuant to the purchase option (the "Purchase
Option") granted pursuant to Section 2(b) of the Purchase Agreement, dated
September 17, 2003, among the Company and Citigroup Global Markets Inc., the
Trustee shall authenticate and deliver Securities for original issue in an
aggregate principal amount of up to $300,000,000.00 plus up to $50,000,000.00
aggregate principal amount of Securities sold pursuant to the Purchase Option,
in each case, if relevant, upon a Company Order without any further action by
the Company. The aggregate principal amount of Securities outstanding at any
time may not exceed the amount set forth in the foregoing sentence, except as
provided in Section 2.07.

                  The Securities shall be issued only in registered form without
coupons and only in principal denominations of $1,000 and any integral multiple
thereof.

                  SECTION 2.03      Registrar, Paying Agent and Conversion
Agent. The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar"), an office
or agency where Securities may be presented for purchase or payment ("Paying
Agent") and an office or agency where Securities may be presented for conversion
("Conversion Agent"). The Registrar shall keep a register of the Securities and
of their transfer and exchange. The Company may have one or more co-registrars,
one or more additional paying agents and one or more additional conversion
agents. The term "Paying Agent" includes any additional paying agent, including
any named pursuant to Section 4.05. The term "Conversion Agent" includes any
additional conversion agent, including any named pursuant to Section 4.05.

                                       14
<PAGE>

                  The Company shall enter into an appropriate agency agreement
with any Registrar or co-registrar, Paying Agent or Conversion Agent (that is
not also the Trustee). The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the
name and address of any such agent. If the Company fails to maintain a
Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and
shall be entitled to appropriate compensation therefor pursuant to Section 7.07.
The Company or any Subsidiary or an Affiliate of either of them may act as
Paying Agent, Registrar, Conversion Agent or co-registrar.

                  The Company initially appoints the Trustee as Registrar,
Conversion Agent and Paying Agent in connection with the Securities.

                  SECTION 2.04      Paying Agent to Hold Money and Securities in
Trust. Except as otherwise provided herein, not later than 11:30 a.m., New York
City time, on each due date of payments in respect of any Security, the Company
shall deposit with the Paying Agent a sum of money (in immediately available
funds if deposited on the due date) or Common Stock sufficient to make such
payments when so becoming due. The Company shall require each Paying Agent (that
is not also the Trustee) to agree in writing that such Paying Agent shall hold
in trust for the benefit of Securityholders or the Trustee all money and Common
Stock held by such Paying Agent for the making of payments in respect of the
Securities and shall notify the Trustee of any default by the Company in making
any such payment. At any time during the continuance of any such default, the
Paying Agent shall, upon the written request of the Trustee, forthwith pay to
the Trustee all money and Common Stock so held in trust. If the Company, a
Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall
segregate the money and Common Stock held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay
all money and Common Stock held by it to the Trustee and to account for any
funds and Common Stock disbursed by it. Upon doing so, such Paying Agent shall
have no further liability for such money or Common Stock.

                  SECTION 2.05      Securityholder Lists. The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Securityholders. If the Trustee is
not the Registrar, the Company shall cause to be furnished to the Trustee at
least semiannually on June 1 and December 1 a listing of Securityholders dated
within 15 days of the date on which the list is furnished and at such other
times as the Trustee may request in writing a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of
Securityholders.

                  Every Holder, by receiving and holding the same, agrees with
the Company and the Trustee that none of the Company, any other obligor, the
Trustee and any agent of any of them shall be held accountable by reason of the
disclosure of any

                                       15
<PAGE>

such list of the names and addresses of Securityholders, regardless of the
source from which such information was derived, and that the Trustee shall not
be held accountable by reason of mailing any material pursuant to a request made
under TIA Section 312(b).

                  SECTION 2.06      Transfer and Exchange. Subject to Section
2.12 hereof,

                  (a)      Upon surrender for registration of transfer of any
Security, together with a written instrument of transfer satisfactory to the
Registrar duly executed by the Securityholder or such Securityholder's attorney
duly authorized in writing, at the office or agency of the Company designated as
Registrar or co-registrar pursuant to Section 2.03 and satisfaction of the
applicable requirements set forth in Section 2.12(b), the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of any authorized
denomination or denominations, of a like aggregate principal amount. The Company
shall not charge a service charge for any registration of transfer or exchange,
but the Company may require payment of a sum sufficient to pay all taxes,
assessments or other governmental charges that may be imposed in connection with
the registration of transfer or exchange of the Securities from the
Securityholder requesting such registration of transfer or exchange.

                  At the option of the Holder, Non-Global Securities may be
exchanged for other Securities of any authorized denomination or denominations,
of a like aggregate principal amount, and upon surrender of the Securities to be
exchanged and satisfaction of the requirements set forth in Section 2.12(b)(3),
the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

                  (b)      The Company shall not be required to make, and the
Registrar need not register, transfers or exchanges of Securities selected for
redemption (except, in the case of Securities to be redeemed in part, the
portion thereof not to be redeemed) or any Securities in respect of which a
Purchase Notice or Change in Control Purchase Notice has been given and not
withdrawn by the Holder thereof in accordance with the terms of this Indenture
(except, in the case of Securities to be purchased in part, the portion thereof
not to be purchased) or any Securities for a period of 15 days before the
mailing of a notice of redemption of Securities to be redeemed.

                  (c)      Successive registrations and registrations of
transfers and exchanges as aforesaid may be made from time to time as desired,
and each such registration shall be noted on the register for the Securities.

                  (d)      Any Registrar appointed pursuant to Section 2.03
hereof shall provide to the Trustee such information as the Trustee may
reasonably require in

                                       16
<PAGE>

connection with the delivery by such Registrar of Securities upon registration
of transfer or exchange of Securities.

                  (e)      No Registrar shall be required to make registrations
of transfer or exchange of Securities during any periods designated in the text
of the Securities or in this Indenture as periods during which such registration
of transfers and exchanges need not be made.

                  (f)      (x) If Securities are issued upon the registration of
transfer, exchange or replacement of Securities subject to restrictions on
transfer and bearing the legends set forth on the form of Security attached
hereto as Exhibit A-1 setting forth such restrictions (collectively, the
"Legend"), the Securities so issued shall bear the Legend, or (y) if a request
is made to remove the Legend on a Security, the Legend shall not be removed, as
the case may be, unless in each case there is delivered to the Company and the
Registrar such satisfactory evidence, which shall include an opinion of counsel,
which counsel is reasonably satisfactory to the Company and the Registrar, as
may be reasonably required by the Company and the Registrar, that neither the
Legend nor the restrictions on transfer set forth therein are required to ensure
that transfers thereof comply with the provisions of Rule 144A or Rule 144 or
that such Securities are not "restricted" within the meaning of Rule 144. Upon
(i) provision of such satisfactory evidence, or (ii) notification by the Company
to the Trustee and Registrar of the sale of such Security pursuant to a
registration statement that is effective at the time of such sale, the Trustee
shall authenticate and deliver a Security that does not bear the Legend. If the
Legend is removed from the face of a Security and the Security is subsequently
held by an Affiliate of the Company, the Company shall use its reasonable best
efforts to reinstate the Legend.

                  The Trustee and the Registrar 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 Security (including any transfers between or
among Depositary participants or beneficial owners of interests in any Global
Security) 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 2.07      Replacement Securities. If (a) any mutilated
Security is surrendered to the Trustee, or (b) the Company, the Guarantor and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Security, and there is delivered to the Company, the Guarantor and
the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of written notice to the Company or the
Trustee that such Security has been acquired by a protected

                                       17
<PAGE>

purchaser within the meaning of Article 8 of the Uniform Commercial Code (a
"Protected Purchaser"), the Company shall execute and the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount, bearing a number not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, or is about to be purchased by
the Company pursuant to Article 3 hereof, the Company in its discretion may,
instead of issuing a new Security, pay or purchase such Security, as the case
may be.

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

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

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

                  SECTION 2.08      Outstanding Securities; Determinations of
Holders' Action. Securities outstanding at any time are all the Securities
authenticated by the Trustee, except for those cancelled by it, those paid
pursuant to Section 2.07 and delivered to it for cancellation, and those
described in this Section 2.08 as not outstanding. A Security does not cease to
be outstanding because the Company or an Affiliate thereof holds the Security;
provided, however, that in determining whether the Holders of the requisite
principal amount of Securities have given or concurred in any request, demand,
authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the
Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, only Securities which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded. Subject to the foregoing,
only Securities outstanding at the time of such determination shall be
considered in any such determination (including, without limitation,
determinations pursuant to Articles 6 and 9).

                                       18
<PAGE>

                  If a Security is replaced pursuant to Section 2.07, the
replaced Security ceases to be outstanding unless the Trustee and the Company
receive proof satisfactory to each of them that the replaced Security is held by
a Protected Purchaser unaware that such Security has been replaced, in which
case the replacement security shall be deemed not to be outstanding.

                  If the Paying Agent holds, in accordance with this Indenture,
on a Redemption Date, or on the Business Day following the Purchase Date or a
Change in Control Purchase Date, or on Stated Maturity, money or securities
(including Common Stock), if permitted hereunder, sufficient to pay Securities
payable on that date, then immediately after such Redemption Date, Purchase
Date, Change in Control Purchase Date or Stated Maturity, as the case may be,
such Securities shall cease to be outstanding, interest on such Securities shall
cease to accrue and all other rights of the Holder shall terminate other than
the right of such Holder to receive payment for such Security upon delivery of
such Security in accordance with the terms of this Indenture; provided that, if
such Securities are to be redeemed, notice of such redemption has been duly
given pursuant to this Indenture.

                  If a Security is converted in accordance with Article 10, then
from and after the time of conversion on the Conversion Date, such Security
shall cease to be outstanding and interest shall cease to accrue on such
Security.

                  SECTION 2.09      Temporary Securities. Pending the
preparation of definitive Securities, the Company may execute, and the Trustee
shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as conclusively evidenced by their execution of such Securities.

                  If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for such purpose
pursuant to Section 2.03, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations. Until so
exchanged the temporary Securities shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities.

                  SECTION 2.10      Cancellation. All Securities surrendered for
payment, purchase by the Company pursuant to Article 3, conversion, redemption
or registration of

                                       19
<PAGE>

transfer or exchange shall, if surrendered to the Company or any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee. The Company may not issue new
Securities to replace Securities it has paid or delivered to the Trustee for
cancellation or that any Holder has converted pursuant to Article 10. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section 2.10, except as expressly permitted by
this Indenture. All cancelled Securities held by the Trustee shall be disposed
of by the Trustee.

                  SECTION 2.11      Persons Deemed Owners. Prior to due
presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
such Security is registered as the owner of such Security for the purpose of
receiving payment of principal of the Security or the payment of any Redemption
Price, Purchase Price or Change in Control Purchase Price in respect thereof or
interest thereon, for the purpose of conversion and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

                  Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global
Securities held by the Depositary, or for maintaining, supervising, or reviewing
any records relating to such beneficial ownership interests or for the
performance by the Depositary or any direct or indirect participant of the
Depositary of their respective obligations under the rules, regulations, and
procedures creating and affecting the Depositary and its operations or any other
statutory, regulatory, contractual, or customary procedures governing their
operations.

                  SECTION 2.12      Transfer of Securities.

                  (a)      Notwithstanding any other provisions of this
Indenture or the Securities, (A) transfers of a Global Security, in whole or in
part, shall be made only in accordance with Section 2.06 and Section 2.12(b)(1),
(B) transfer of a beneficial interest in a Global Security for a Non-Global
Security shall comply with Section 2.06 and Section 2.12(b)(2) below, (C)
transfers of a Non-Global Security shall comply with Section 2.06 and Section
2.12(b)(3), (D) transfers of a Non-Global Security for a beneficial interest in
a Global Security shall comply with Section 2.06 and Section 2.12(b)(4) below
and (E) transfers of beneficial interests in Global Securities shall be made in
accordance with Section 2.12(b)(5) below.

                                       20
<PAGE>

                  No transfer of a Security to any Person shall be effective
under this Indenture or the Securities unless and until such Security has been
registered in the name of such Person.

                  (b)      Transfer Requirements.

                  (1)      Restrictions on Transfers of Global Securities. A
         Global Security may not be transferred, in whole or in part, to any
         Person other than the Depositary, and no such transfer to any such
         other Person may be registered; provided that this Section 2.12(b)(1)
         shall not prohibit any transfer of a Security that is issued in
         exchange for a Global Security but is not itself a Global Security.
         Nothing in this Section 2.12(b)(1) shall prohibit or render ineffective
         any transfer of a beneficial interest in a Global Security effected in
         accordance with the other provisions of this Section 2.12(b).

                  (2)      Restrictions on Transfer of a Beneficial Interest in
         a Global Security for a Non-Global Security. A beneficial interest in a
         Global Security may not be exchanged for a Non-Global Security except
         pursuant to Section 2.12(f)(1)(ii) and (iii) and upon satisfaction of
         the requirements set forth below. Upon receipt by the Trustee of a
         request for transfer of a beneficial interest in a Global Security in
         accordance with Applicable Procedures for a Non-Global Security in the
         form satisfactory to the Trustee, together with:

                           (i)      so long as the Securities are Restricted
                  Securities, certification, in the form set forth in Exhibit B;

                           (ii)     written instructions to the Trustee to make,
                  or direct the Registrar to make, an adjustment on its books
                  and records with respect to such Global Security to reflect a
                  decrease in the aggregate principal amount of the Securities
                  represented by the Global Security, such instructions to
                  contain information regarding the Depositary account to be
                  credited with such decrease; and

                           (iii)    if the Company or Registrar so requests, an
                  opinion of counsel, which counsel is reasonably acceptable to
                  the Company and the Registrar, or other evidence reasonably
                  satisfactory to them as to the compliance with the
                  restrictions set forth in the Legend,

         then the Trustee shall cause, or direct the Registrar to cause, in
         accordance with the standing instructions and procedures existing
         between the Depositary and the Registrar, the aggregate principal
         amount of Securities represented by the Global Security to be decreased
         by the aggregate principal amount of the Non-Global Security to be
         issued, shall authenticate and deliver such Non-Global Security and

                                       21

<PAGE>

         shall instruct the Depositary to debit or cause to be debited to the
         account of the Person specified in such instructions a beneficial
         interest in the Global Security equal to the principal amount of the
         Non-Global Security so issued.

                  (3)      Transfer and Exchange of Non-Global Securities. When
         Non-Global Securities are presented to the Registrar with a request:

                           (x)      to register the transfer of such Non-Global
                  Securities; or

                           (y)      to exchange such Non-Global Securities for
                  an equal principal amount of Non-Global Securities of other
                  authorized denominations,

         the Registrar shall register the transfer or make the exchange as
         requested if its reasonable requirements for such transaction are met;
         provided, however, that the Non-Global Securities surrendered for
         registration of transfer or exchange:

                           (i)      shall be duly endorsed or accompanied by a
                  written instrument of transfer in form reasonably satisfactory
                  to the Company and the Registrar, duly executed by the Holder
                  thereof or his attorney duly authorized in writing; and

                           (ii)     so long as such Securities are Restricted
                  Securities, such Securities are being transferred or exchanged
                  pursuant to an effective registration statement under the
                  Securities Act or, if being transferred pursuant to clause
                  (A), (B) or (C) below, are accompanied by the additional
                  information and documents specified in each clause, as
                  applicable:

                                    (A)      if such Non-Global Securities are
                           being delivered to the Registrar by a Holder for
                           registration in the name of such Holder, without
                           transfer, a certification from such Holder to that
                           effect; or

                                    (B)      if such Non-Global Securities are
                           being transferred to the Company, a certification to
                           that effect; or

                                    (C)      if such Non-Global Securities are
                           being transferred pursuant to an exemption from
                           registration (i) a certification to that effect (in
                           the form set forth in Exhibit B, if applicable) and
                           (ii) if the Company or Registrar so requests, an
                           opinion of counsel, which counsel is reasonably
                           acceptable to the Company and the Registrar, or other
                           evidence reasonably satisfactory to them as to the
                           compliance with the restrictions set forth in the
                           Legend.

                  (4)      Restrictions on Transfer of a Non-Global Security for
         a Beneficial Interest in a Global Security. A Non-Global Security may
         not be exchanged for a beneficial interest in a Global Security except
         upon satisfaction of the requirements set forth below. Upon receipt by
         the Trustee of a Non-Global Security, duly endorsed or accompanied by
         appropriate instruments of transfer, in form satisfactory to the
         Trustee, together with:

                           (i)      so long as the Securities are Restricted
                  Securities, certification, in the form set forth in Exhibit B,
                  that such Non-Global Security is being transferred to a QIB in
                  accordance with Rule 144A; and

                           (ii)     written instructions directing the Trustee
                  to make, or to direct the Registrar to make, an adjustment on
                  its books and records with respect to such Global Security to
                  reflect an increase in the aggregate principal amount of the
                  Securities represented by the Global Security, such
                  instructions to contain information regarding the Depositary
                  account to be credited with such increase,

         then the Trustee shall cancel such Non-Global Security and cause, or
         direct the Registrar to cause, in accordance with the standing
         instructions and procedures existing between the Depositary and the
         Registrar, the aggregate principal amount of Securities represented by
         the Global Security to be increased by the aggregate principal amount
         of the Non-Global Security to be exchanged, and shall instruct the
         Depositary to credit or cause to be credited to the account of the
         Person specified in such instructions a beneficial interest in the
         Global Security equal to the principal amount of the Non-Global
         Security so cancelled. If no Global Securities are then outstanding,
         the Company shall issue and the Trustee shall authenticate a new Global
         Security in the appropriate principal amount.

                  (5)      Restrictions on Transfer of a Beneficial Interest in
         a Global Security. Transfers of beneficial interests in a Global
         Security shall only be effected through the Depositary in accordance
         with this Indenture and the Applicable Procedures therefor.

                  (c)      Subject to the succeeding Section 2.12(d), every
Security shall be subject to the restrictions on transfer provided in the Legend
including the requirement of the delivery of an opinion of counsel, if so
provided. Whenever any Restricted Security is presented or surrendered for
registration of transfer or for exchange for a Security registered in a name
other than that of the Holder, such Security must be accompanied by a
certificate in substantially the form set forth in Exhibit B, dated the date of
such surrender and signed by the Holder of such Security, as to compliance with
such restrictions on transfer. The Registrar shall not be required to accept for
such registration

                                       23

<PAGE>

of transfer or exchange any Security not so accompanied by a properly completed
certificate.

                  (d)      The restrictions imposed by the Legend upon the
transferability of any Security shall cease and terminate when such Security has
been sold pursuant to an effective registration statement under the Securities
Act or transferred in compliance with Rule 144 or, if earlier, upon the
expiration of the holding period applicable to transfers thereof under paragraph
(k) of Rule 144. Any Security as to which such restrictions on transfer shall
have expired in accordance with their terms or shall have terminated may, upon a
surrender of such Security for exchange to the Registrar in accordance with the
provisions of this Section 2.12 (accompanied, in the event that such
restrictions on transfer have terminated by reason of a transfer in compliance
with Rule 144, by an opinion of counsel having substantial experience in
practice under the Securities Act and otherwise reasonably acceptable to the
Company, addressed to the Company, the Trustee and the Registrar and in form
acceptable to the Company, to the effect that the transfer of such Security has
been made in compliance with Rule 144), be exchanged for a new Security, of like
tenor and aggregate principal amount, which shall not bear the restrictive
Legend. The Company shall inform the Trustee of the effective date of any
registration statement registering the Securities under the Securities Act. The
Trustee and the Registrar shall not be liable for any action taken or omitted to
be taken by it in good faith in accordance with the aforementioned opinion of
counsel or registration statement.

                  (e)      As used in Section 2.12, the term "transfer"
encompasses any sale, pledge, transfer, hypothecation or other disposition of
any Security.

                  (f)      The provisions of clauses (1), (2), (3), (4) and (5)
below shall apply only to Global Securities:

                  (1)      Notwithstanding any other provisions of this
         Indenture or the Securities, except as provided in Section 2.12(b)(1),
         a Global Security shall not be exchanged in whole or in part for a
         Security registered in the name of any Person other than the
         Depositary, provided that a Global Security may be exchanged for
         Securities registered in the names of any Person designated by the
         Depositary in the event that (i) the Depositary has notified the
         Company that it is unwilling or unable to continue as Depositary for
         such Global Security or such Depositary has ceased to be a "clearing
         agency" registered under the Exchange Act, and a successor Depositary
         is not appointed by the Company within 90 days, (ii) the Company elects
         to discontinue use of the system of book-entry transfer through DTC (or
         any successor depositary), or (iii) an Event of Default has occurred
         and is continuing. Any Global Security exchanged pursuant to subclause
         (i) of this clause (1) shall be so exchanged in whole and not in part,
         and any Global Security exchanged pursuant to subclause (ii) of this
         clause (1) may be exchanged in whole or from time to time in part as
         directed by the Depositary. Any Security issued in

                                       24

<PAGE>

         exchange for a Global Security or any portion thereof shall be a Global
         Security; provided that any such Security so issued that is registered
         in the name of a person other than the Depositary or a nominee thereof
         shall not be a Global Security.

                  (2)      Securities issued in exchange for a Global Security
         or any portion thereof shall be issued in definitive, fully registered
         form, without interest coupons, shall have an aggregate principal
         amount equal to that of such Global Security 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 the applicable legends provided for herein. Any Global Security to
         be exchanged in whole shall be surrendered by the Depositary to the
         Trustee, as Registrar. With regard to any Global Security to be
         exchanged in part, either such Global Security 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 Security, 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 deliver the Security
         issuable on such exchange to or upon the order of the Depositary or an
         authorized representative thereof.

                  (3)      Subject to the provisions of clause (5) below, the
         registered Holder may grant proxies and otherwise authorize any Person,
         including Agent Members (as defined below) and persons that may hold
         interests through Agent Members, to take any action which a holder is
         entitled to take under this Indenture or the Securities.

                  (4)      In the event of the occurrence of any of the events
         specified in clause (1)(ii) or (iii) above, the Company will promptly
         make available to the Trustee a reasonable supply of Non-Global
         Securities in definitive, fully registered form, without interest
         coupons.

                  (5)      Neither any members of, or participants in, the
         Depositary (collectively, the "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 Security registered in the name of
         the Depositary or under any such Global Security, and the Depositary
         may be treated by the Company, the Trustee, the Registrar, the Paying
         Agent and any agent of the Company, the Trustee, the Registrar or the
         Paying Agent as the absolute owner and holder of such Global Security
         for all purposes whatsoever. Notwithstanding the foregoing, nothing
         herein shall prevent the Company, the Guarantor or the Trustee or any
         agent of the Company, the Guarantor or the Trustee from giving effect
         to any written certification, proxy or other authorization furnished by
         the Depositary, or impair,

                                       25

<PAGE>

         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 Security.

                  SECTION 2.13      CUSIP Numbers. The Company in issuing the
Securities 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
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the CUSIP numbers
known to an Officer of the Company.

                                    ARTICLE 3

                            REDEMPTION AND PURCHASES

                  SECTION 3.01      Right to Redeem; Notices to Trustee. The
Company, at its option, may redeem the Securities in accordance with the
provisions of paragraphs 5 and 7 of the Securities. Prior to September 23, 2008,
the Company cannot redeem the Securities. Beginning on September 23, 2008, the
Company may redeem the Securities for cash in whole at any time, or in part from
time to time. If the Company elects to redeem Securities pursuant to paragraph 5
of the Securities, it shall notify the Trustee in writing of the Redemption Date
and the principal amount of Securities to be redeemed and the amount of accrued
and unpaid interest, if any, payable on the Redemption Date.

                  The Company shall give the notice to the Trustee provided for
in this Section 3.01, at least 45 days but not more than 60 days before the
Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).
If fewer than all the Securities are to be redeemed, the record date relating to
such redemption shall be selected by the Company and given to the Trustee, which
record date shall not be less than ten days after the date of notice to the
Trustee.

                  SECTION 3.02      Selection of Securities to Be Redeemed. If
less than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by any other method the Trustee
considers fair and appropriate (so long as such method is not prohibited by the
rules of any stock exchange on which the Securities are then listed). The
Trustee shall make the selection at least 30 days but not more than 60 days
before the Redemption Date from outstanding Securities not previously called for
redemption. The Trustee may select for redemption portions of the principal
amount of Securities that have denominations larger than $1,000.

                                       26

<PAGE>

                  Securities and portions of them the Trustee selects shall be
in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of Securities to be redeemed.

                  If any Security selected for partial redemption is converted
in part before termination of the conversion right with respect to the portion
of the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption. Securities
which have been converted during a selection of Securities to be redeemed may be
treated by the Trustee as outstanding for the purpose of such selection.

                  SECTION 3.03      Notice of Redemption. At least 30 days but
not more than 60 days before a Redemption Date, the Company shall mail a notice
of redemption by first-class mail, postage prepaid, to each Holder of Securities
to be redeemed.

                  The notice shall identify the Securities to be redeemed and
shall state:

                  (1)      the Redemption Date;

                  (2)      the Redemption Price and accrued and unpaid interest,
         if any, payable on the Redemption Date;

                  (3)      the Conversion Rate;

                  (4)      the name and address of the Paying Agent and
         Conversion Agent;

                  (5)      that Securities called for redemption may be
         converted at any time before the close of business on the second
         Business Day immediately preceding the Redemption Date, even if not
         otherwise convertible at such time;

                  (6)      that Holders who want to convert Securities must
         satisfy the requirements set forth in paragraph 8 of the Securities;

                  (7)      that Securities called for redemption must be
         surrendered to the Paying Agent to collect the Redemption Price and
         accrued and unpaid interest, if any;

                  (8)      if fewer than all the outstanding Securities are to
         be redeemed, the certificate number and principal amounts of the
         particular Securities to be redeemed;

                                       27

<PAGE>

                  (9)      that, unless the Company defaults in making payment
         of such Redemption Price and any interest which is due and payable,
         interest will cease to accrue on and after the Redemption Date;

                  (10)     the CUSIP number of the Securities; and

                  (11)     any other information the Company wants to present.

                  At the Company's request, the Trustee shall give the notice of
redemption to Holders in the Company's name and at the Company's expense,
provided that the Company makes such request at least five Business Days (unless
a shorter period shall be reasonably satisfactory to the Trustee) prior to the
date such notice of redemption must be mailed.

                  SECTION 3.04      Effect of Notice of Redemption. Once notice
of redemption is given, Securities called for redemption become due and payable
on the Redemption Date and at the Redemption Price (together with accrued and
unpaid interest, if any, to but not including the date of redemption) stated in
the notice except for Securities which are converted in accordance with the
terms of this Indenture. Upon the later of the Redemption Date and surrender to
the Paying Agent, such Securities shall be paid at the Redemption Price
(together with accrued and unpaid interest, if any, to but not including the
date of redemption) stated in the notice.

                  SECTION 3.05      Deposit of Redemption Price. Prior to 11:30
a.m. (New York City time) on any Redemption Date, the Company shall deposit with
the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of
them is the Paying Agent, shall segregate and hold in trust) money sufficient to
pay the Redemption Price of, and any accrued and unpaid interest to but not
including the date of redemption with respect to, all Securities to be redeemed
on that date other than Securities or portions of Securities called for
redemption which on or prior thereto have been delivered by the Company to the
Trustee for cancellation or have been converted in accordance with this
Indenture. The Paying Agent shall as promptly as practicable return to the
Company any money not required for that purpose because of conversion of
Securities pursuant to Article 10. If such money is then held by the Company or
a Subsidiary or an Affiliate of either of them in trust and is not required for
such purpose it shall be discharged from such trust.

                  SECTION 3.06      Securities Redeemed in Part. Upon surrender
of a Security that is redeemed in part, the Company shall execute and the
Trustee shall authenticate and deliver to the Holder a new Security in an
authorized denomination equal in principal amount to the unredeemed portion of
the Security surrendered.

                                       28

<PAGE>

                  SECTION 3.07      Conversion Arrangement on Call for
Redemption. In connection with any redemption of Securities, the Company may
arrange for the purchase and conversion of any Securities called for redemption
by an agreement with one or more investment banks or other purchasers to
purchase such Securities by paying to the Trustee in trust for the
Securityholders, on or prior to 11:30 a.m. New York City time on the Redemption
Date, an amount that, together with any amounts deposited with the Trustee by
the Company for the redemption of such Securities, is not less than the
Redemption Price of, and any accrued and unpaid interest with respect to, such
Securities. Notwithstanding anything to the contrary contained in this Article
3, the obligation of the Company to pay the Redemption Prices of such Securities
shall be deemed to be satisfied and discharged to the extent such amount is so
paid by such purchasers. If such an agreement is entered into, any Securities
not duly surrendered for conversion by the Holders thereof may, at the option of
the Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article 10) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on the Business Day prior to the
Redemption Date, subject to payment of the above amount as aforesaid. The
Trustee shall hold and pay to the Holders whose Securities are selected for
redemption any such amount paid to it for purchase and conversion in the same
manner as it would moneys deposited with it by the Company for the redemption of
Securities. Without the Trustee's prior written consent, no arrangement between
the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture,
and the Company agrees to indemnify the Trustee from, and hold it harmless
against, any loss, liability or expense arising out of or in connection with any
such arrangement for the purchase and conversion of any Securities between the
Company and such purchasers, including the costs and expenses incurred by the
Trustee in the defense of any claim or liability arising out of or in connection
with the exercise or performance of any of its powers, duties, responsibilities
or obligations under this Indenture.

                  SECTION 3.08      Purchase of Securities at Option of the
Holder.

                  (a)      General. Securities shall be purchased by the Company
pursuant to paragraph 6 of the Securities as of each September 23, 2008, 2013
and 2018 (each, a "Purchase Date"), at a purchase price equal to the principal
amount thereof plus accrued and unpaid interest, if any, to the Purchase Date
(the "Purchase Price"), at the option of the Holder thereof, upon the
satisfaction of all of the following:

                  (1)      delivery to the Paying Agent by the Holder of a
         written notice of purchase (a "Purchase Notice") at any time from the
         opening of business on the date that is 20 Business Days prior to a
         Purchase Date until the close of business on the second Business Day
         immediately preceding such Purchase Date stating:

                                       29

<PAGE>

                           (A)      if certificated shares have been issued, the
                  certificate number of the Security which the Holder will
                  deliver to be purchased,

                           (B)      the portion of the principal amount of the
                  Security which the Holder will deliver to be purchased, which
                  portion must be a principal amount of $1,000 or an integral
                  multiple thereof,

                           (C)      that such Security shall be purchased as of
                  the Purchase Date pursuant to the terms and conditions
                  specified in paragraph 6 of the Securities and in this
                  Indenture, and

                           (D)      in the event the Company elects, pursuant to
                  Section 3.08(b), to pay the Purchase Price to be paid as of
                  such Purchase Date, in whole or in part, in shares of Common
                  Stock but such portion of the Purchase Price shall ultimately
                  be payable to such Holder entirely in cash because any of the
                  conditions to payment of the Purchase Price in Common Stock,
                  as set forth in Section 3.08(d), is not satisfied prior to the
                  close of business on such Purchase Date, whether such Holder
                  elects (i) to withdraw such Purchase Notice as to some or all
                  of the Securities to which such Purchase Notice relates
                  (stating the principal amount and certificate numbers of the
                  Securities as to which such withdrawal shall relate), or (ii)
                  to receive cash in respect of the entire Purchase Price for
                  all Securities (or portions thereof) to which such Purchase
                  Notice relates; and

                  (2)      delivery or book entry transfer of such Security to
         the Paying Agent prior to, on or after the Purchase Date (together with
         all necessary endorsements) at the offices of the Paying Agent, such
         delivery being a condition to receipt by the Holder of the Purchase
         Price therefor; provided, however, that such Purchase Price shall be so
         paid pursuant to this Section 3.08 only if the Security so delivered to
         the Paying Agent shall conform in all respects to the description
         thereof in the related Purchase Notice, as determined by the Company.

                  If a Holder, in such Holder's Purchase Notice and in any
written notice of withdrawal delivered by such Holder pursuant to the terms of
Section 3.10, fails to indicate such Holder's choice with respect to the
election set forth in clause (D) of Section 3.08(a)(1), such Holder shall be
deemed to have elected to receive cash in respect of the Purchase Price for all
Securities subject to such Purchase Notice in the circumstances set forth in
such clause (D).

                  The Company shall purchase from the Holder thereof, pursuant
to this Section 3.08, a portion of a Security if the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

<PAGE>

                  Any purchase by the Company contemplated pursuant to the
provisions of this Section 3.08 shall be consummated by the delivery of the
consideration to be received by the Holder promptly following the later of the
Purchase Date and the time of delivery of the Security to the Paying Agent in
accordance with this Section 3.08.

                  Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Purchase Notice contemplated by this Section
3.08(a) shall have the right to withdraw such Purchase Notice at any time prior
to the close of business on the Business Day prior to the Purchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 3.10.

                  The Paying Agent shall promptly notify the Company of the
receipt by it of any Purchase Notice or written notice of withdrawal thereof.

                  (b)      Company's Right to Elect Manner of Payment of
Purchase Price. The Securities to be purchased pursuant to Section 3.08(a) may
be paid for, at the election of the Company, in U.S. legal tender ("cash") or
Common Stock, or in any combination of cash and Common Stock, subject to the
conditions set forth in Sections 3.08(c) and (d), as applicable. The Company
shall designate, in the Company Notice delivered pursuant to Section 3.08(e),
whether the Company will purchase the Securities for cash or Common Stock, or,
if a combination thereof, the percentages or amounts of the Purchase Price of
Securities in respect of which it will pay in cash or Common Stock; provided
that the Company will pay cash for fractional interests in Common Stock. For
purposes of determining the existence of potential fractional interests, all
Securities subject to purchase by the Company held by a Holder shall be
considered together (no matter how many separate certificates are to be
presented). Each Holder whose Securities are purchased pursuant to this Section
3.08 shall receive the same percentage of cash or Common Stock in payment of the
Purchase Price for such Securities, except (i) as provided in Section 3.08(d)
with regard to the payment of cash in lieu of fractional shares of Common Stock
and (ii) in the event that the Company is unable to purchase the Securities of a
Holder or Holders of Common Stock because any necessary qualifications or
registrations of the Common Stock under applicable state securities laws cannot
be obtained, the Company may purchase the Securities of such Holder or Holders
for cash. The Company may not change its election with respect to the
consideration (or components or percentages of components thereof) to be paid
once the Company has given its Company Notice to Securityholders except pursuant
to this Section 3.08(b) or pursuant to Section 3.08(d) in the event of a failure
to satisfy, prior to the close of business on the Purchase Date, any condition
to the payment of the Purchase Price, in whole or in part, in Common Stock.

                  At least three Business Days before the Company Notice Date,
the Company shall deliver an Officers' Certificate to the Trustee specifying:

                                       31

<PAGE>

                  (1)      the manner of payment selected by the Company,

                  (2)      the information required by Section 3.08(e),

                  (3)      if the Company elects to pay the Purchase Price, or a
         specified percentage thereof, in Common Stock, that the conditions to
         such manner of payment set forth in Section 3.08(d) have been or will
         be complied with, and

                  (4)      whether the Company desires the Trustee to give the
         Company Notice required by Section 3.08(e).

                  (c)      Purchase with Cash. On each Purchase Date, at the
option of the Company, the Purchase Price of Securities in respect of which a
Purchase Notice pursuant to Section 3.08(a) has been given and not withdrawn, or
a specified percentage thereof, may be paid by the Company with cash equal to
the aggregate Purchase Price of such Securities.

                  (d)      Payment by Issuance of Common Stock. On each Purchase
Date, at the option of the Company, the Purchase Price of Securities in respect
of which a Purchase Notice pursuant to Section 3.08(a) has been given, or a
specified percentage thereof, may be paid by the Company by the issuance of a
number of shares of Common Stock equal to the quotient obtained by dividing (i)
the amount of cash to which the Securityholders would have been entitled had the
Company elected to pay all or such specified percentage, as the case may be, of
the Purchase Price of such Securities in cash by (ii) the Market Price of a
share of Common Stock, subject to the next succeeding paragraph.

                  The Company will not issue a fractional share of Common Stock
in payment of the Purchase Price. Instead the Company will pay cash for the
current market value of the fractional share. The current market value of a
fraction of a share shall be determined by multiplying the Market Price by such
fraction and rounding the product to the nearest whole cent. If a Holder elects
to have more than one Security purchased, the number of shares of Common Stock
shall be based on the aggregate amount of Securities to be purchased.

                  Upon a payment by Common Stock pursuant to the terms hereof,
that portion of accrued and unpaid interest, if any, attributable to the period
from the Issue Date to the Purchase Date with respect to the purchased Security
shall not be cancelled, extinguished or forfeited but rather shall be deemed
paid in full to the Holder through the delivery of the Common Stock in exchange
for the Security being purchased pursuant to the terms hereof, and the fair
market value of such Common Stock (together with any cash payments in lieu of
fractional shares of Common Stock) shall be treated as issued, to the extent
thereof, first in exchange for the accrued and unpaid interest, if any, through

                                       32

<PAGE>

the Purchase Date, and the balance, if any, of the fair market value of such
shares of Common Stock shall be treated as issued in exchange for the principal
amount of the Security being purchased pursuant to the provisions hereof.

                  The Company's right to exercise its election to purchase the
Securities pursuant to this Section 3.08 through the issuance of shares of
Common Stock shall be conditioned upon:

                  (1)      the Company's not having given its Company Notice of
         an election to pay entirely in cash and its giving of timely Company
         Notice of election to purchase all or a specified percentage of the
         Securities with Common Stock as provided herein;

                  (2)      the shares of Common Stock having been admitted for
         listing or admitted for listing subject to notice of issuance on the
         New York Stock Exchange or if the Common Stock is not then listed on
         the New York Stock Exchange, on such other United States securities
         exchange on which the Common Stock is then listed or, if the Common
         Stock is not then listed on a United States securities exchange, as
         quoted on the National Association of Securities Dealers Automated
         Quotation System;

                  (3)      the registration of the shares of Common Stock to be
         issued in respect of the payment of the Purchase Price under the
         Securities Act of 1933, as amended (the "Securities Act"), or the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), in
         each case, if required;

                  (4)      any necessary qualification or registration under
         applicable state securities laws or the availability of an exemption
         from such qualification and registration; and

                  (5)      the receipt by the Trustee of (A) an Officers'
         Certificate stating that the terms of the issuance of the Common Stock
         are in conformity with this Indenture and that conditions (1), (2), (3)
         and (4) above and the condition set forth in the second succeeding
         sentence have been satisfied and (B) an Opinion of Counsel to the
         effect that the shares of Common Stock to be issued by the Company in
         payment of the Purchase Price in respect of Securities have been duly
         authorized and, when issued and delivered pursuant to the terms of this
         Indenture in payment of the Purchase Price in respect of the
         Securities, will be validly issued, fully paid and non-assessable and,
         to the best of such counsel's knowledge, free from preemptive rights
         under applicable state law or material contracts.

                                       33

<PAGE>

                  Such Officers' Certificate shall also set forth the number of
shares of Common Stock to be issued for each $1,000 principal amount of
Securities and the Sale Price of a share of Common Stock on each trading day
during the period for which the Market Price is calculated. The Company may pay
the Purchase Price (or any portion thereof) in Common Stock only if the
information necessary to calculate the Market Price is published in a daily
newspaper of national circulation. If the foregoing conditions are not satisfied
with respect to a Holder or Holders prior to the close of business on the
Purchase Date and the Company has elected to purchase the Securities pursuant to
this Section 3.08 through the issuance of shares of Common Stock, the Company
shall pay the entire Purchase Price of the Securities of such Holder or Holders
in cash.

                  The "Market Price" of the Common Stock means the average of
the Sale Prices of the Common Stock for the five trading day period ending on
the third Business Day (if the third Business Day prior to the applicable
Purchase Date (or Change in Control Purchase Date, as applicable) is a trading
day or, if not, then on the last trading day prior to such third Business Day)
prior to the applicable Purchase Date (or Change in Control Purchase Date, as
applicable), appropriately adjusted to take into account the occurrence, during
the period commencing on the first of such trading days during such five trading
day period and ending on such Purchase Date (or Change in Control Purchase Date,
as applicable), of any event described in Section 10.06, 10.07 or 10.08;
subject, however, to the conditions set forth in Sections 10.09 and 10.10.

                  (e)      Notice of Election. The Company's notice of election
to purchase with cash or Common Stock or any combination thereof (the "Company
Notice") shall be sent to the Holders (and to beneficial owners as required by
applicable law) in the manner provided in Section 13.02 no later than 20 days
prior to the Purchase Date (the "Company Notice Date"). Such Company Notice
shall state the manner of payment elected and shall contain the following
information:

                  In the event the Company has elected to pay the Purchase Price
(or a specified percentage thereof) with Common Stock, the Company Notice shall:

                  (1)      state that each Holder will receive Common Stock with
         a Market Price determined as of a specified date prior to the Purchase
         Date equal to such specified percentage of the Purchase Price of the
         Securities held by such Holder (except any cash amount to be paid in
         lieu of fractional shares);

                  (2)      set forth the method of calculating the Market Price
         of the Common Stock; and

                  (3)      state that because the Market Price of Common Stock
         will be determined prior to the Purchase Date, Holders will bear the
         market risk with

                                       34

<PAGE>

         respect to the value of the Common Stock to be received from the date
         such Market Price is determined to the Purchase Date.

                  In any case, each Company Notice shall include a form of
Purchase Notice to be completed by a Securityholder and shall state:

                  (i)      the Purchase Price and the Conversion Rate;

                  (ii)     whether the Company will pay the Purchase Price in
         cash or in Common Stock or any combination thereof, specifying the
         percentage of each;

                  (iii)    the name and address of the Paying Agent and the
         Conversion Agent;

                  (iv)     that Securities as to which a Purchase Notice has
         been given may be converted pursuant to Article 10 hereof only if the
         applicable Purchase Notice has been withdrawn in accordance with the
         terms of this Indenture;

                  (v)      that Securities must be surrendered to the Paying
         Agent to collect payment of the Purchase Price;

                  (vi)     that the Purchase Price for any Security as to which
         a Purchase Notice has been given and not withdrawn will be paid
         promptly following the later of the Purchase Date and the time of
         surrender of such Security as described in (v);

                  (vii)    the procedures the Holder must follow to exercise
         rights under Section 3.08 and a brief description of those rights;

                  (viii)   briefly, the conversion rights of the Securities and
         that Holders who want to convert Securities must satisfy the
         requirements set forth in paragraph 8 of the Securities;

                  (ix)     the procedures for withdrawing a Purchase Notice
         (including, without limitation, for a conditional withdrawal pursuant
         to the terms of Section 3.08(a)(1)(D) or Section 3.10);

                  (x)      that, unless the Company defaults in making payment
         of such Purchase Price, interest on Securities surrendered for purchase
         will cease to accrue on and after the Purchase Date; and

                  (xi)     the CUSIP number of the Securities.

                                       35

<PAGE>

                  At the Company's request, the Trustee shall give such Company
Notice in the Company's name and at the Company's expense; provided, however,
that, in all cases, the text of such Company Notice shall be prepared by the
Company.

                  Upon determination of the actual number of shares of Common
Stock to be issued for each $1,000 principal amount of Securities, the Company
will issue a press release through Dow Jones & Company, Inc. or Bloomberg
Business News containing this information and publish such determination on the
Company's web site on the World Wide Web or through such other public medium as
the Company may use at that time.

                  (f)      Covenants of the Company. All shares of Common Stock
delivered upon purchase of the Securities shall be newly issued shares or
treasury shares, shall be duly authorized, validly issued, fully paid and
nonassessable and shall be free from preemptive rights and free of any lien or
adverse claim created by the Company.

                  (g)      Procedure upon Purchase. The Company shall deposit
cash (in respect of a cash purchase under Section 3.08(c) or for fractional
interests as applicable) or shares of Common Stock, or a combination thereof, as
applicable, at the time and in the manner as provided in Section 3.11,
sufficient to pay the aggregate Purchase Price of all Securities to be purchased
pursuant to this Section 3.08. As soon as practicable after the Purchase Date,
the Company shall deliver to each Holder entitled to receive Common Stock
through the Paying Agent, a certificate for the number of full shares of Common
Stock issuable in payment of the Purchase Price and cash in lieu of any
fractional interests. The person in whose name the certificate for Common Stock
is registered shall be treated as a holder of record of shares of Common Stock
on the Business Day following the Purchase Date. Subject to Section 3.08(d), no
payment or adjustment will be made for dividends on the Common Stock the record
date for which occurred on or prior to the Purchase Date.

                  (h)      Taxes. If a Holder of a Security is paid in Common
Stock, the Company shall pay any documentary, stamp or similar issue or transfer
tax due on such issue of shares of Common Stock. However, the Holder shall pay
any such tax which is due because the Holder requests the shares of Common Stock
to be issued in a name other than the Holder's name. The Paying Agent may refuse
to deliver the certificates representing the Common Stock being issued in a name
other than the Holder's name until the Paying Agent receives a sum sufficient to
pay any tax which will be due because the shares of Common Stock are to be
issued in a name other than the Holder's name. Nothing herein shall preclude any
income tax withholding required by law or regulations.

                  SECTION 3.09      Purchase of Securities at Option of the
Holder upon Change in Control.

                  (a)      If there shall have occurred a Change in Control as
defined below, Securities shall be purchased by the Company, at the option of
the Holder thereof, at a purchase price equal to the principal amount thereof,
plus accrued and unpaid interest, if any (the "Change in Control Purchase
Price"), as of the date selected by the Company that is no later than 30
Business Days after the occurrence of the Change in Control but in no event
prior to the date on which such Change in Control occurs (the "Change in Control
Purchase Date"), subject to satisfaction by or on behalf of the Holder of the
requirements set forth in Section 3.09(c).

                  A "Change in Control" means the occurrence of any of the
following after the Securities are originally issued pursuant to this Indenture:

                  (1)      any "person" or "group" within the meaning of Section
         13(d) of the Exchange Act other than the Company, any subsidiary of the
         Company or the Guarantor, or any Employee Benefit Plan of the Company,
         the Guarantor, or any of their respective subsidiaries, files a
         Schedule TO or any schedule, form or report under the Exchange Act
         disclosing that such person or group has become the direct or indirect
         ultimate "beneficial owner," as defined in Rule 13d-3 under the
         Exchange Act, of the Company's common equity representing more than 50%
         of the voting power of the Company's common equity entitled to vote
         generally in the election of directors;

                  (2)      any "person" or "group" within the meaning of Section
         13(d) of the Exchange Act other than the Company, any subsidiary of the
         Company or the Guarantor, or any Employee Benefit Plan of the Company,
         the Guarantor or any of their respective subsidiaries, becomes (whether
         by purchase, share exchange, consolidation, merger or otherwise) the
         direct or indirect ultimate "beneficial owner," as defined in Rule
         13d-3 under the Exchange Act, of the Guarantor's common equity
         representing more than 50% of the voting power of the Guarantor's
         common equity entitled to vote generally in the election of directors;
         provided, however, that if such person or group became such a direct or
         indirect "beneficial owner" of the Guarantor's common equity as a
         result of a transaction involving the Company that does not otherwise
         constitute a change in control under this provision, then any
         beneficial ownership of the Guarantor's common stock by such person or
         group shall not be a change in control under this clause (2);

                  (3)      consummation of any share exchange, consolidation or
         merger of the Company pursuant to which the Company's Common Stock will
         be converted into cash, securities or other property or any sale, lease
         or other transfer in one

                                       37

<PAGE>

         transaction or a series of transactions of all or substantially all of
         the consolidated assets of either the Company and its subsidiaries,
         taken as a whole, or the Guarantor and its subsidiaries, taken as a
         whole, to any person other than the Company, the Guarantor or one or
         more of subsidiaries of the Company or the Guarantor; provided,
         however, that a transaction where the holders of the Company's or the
         Guarantor's common equity immediately prior to such transaction have,
         directly or indirectly, more than 50% of the aggregate voting power of
         all classes of common equity of the continuing or surviving corporation
         or transferee entitled to vote generally in the election of directors
         immediately after such event shall not be a change in control;

                  (4)      during any period of 12 consecutive months,
         individuals who at the beginning of such period constitute the
         Company's Board of Directors (together with any new director whose
         election by the Company's Board of Directors or whose nomination for
         election by the Company's stockholders was approved by a vote of at
         least a majority of the directors then still in office who either were
         directors at the beginning of such period or whose election or
         nomination for election was previously approved) cease for any reason
         (other than death or disability) to constitute a majority of the
         directors then in office; or

                  (5)      during any period of 12 consecutive months,
         individuals who at the beginning of such period constitute the
         Guarantor's Board of Directors (together with any new director whose
         election by the Guarantor's Board of Directors or whose nomination for
         election by the Guarantor's stockholders was approved by a vote of at
         least a majority of the directors then still in office who either were
         directors at the beginning of such period or whose election or
         nomination for election was previously approved) cease for any reason
         (other than death or disability) to constitute a majority of the
         directors then in office.

                  A Change in Control will not be deemed to have occurred in
respect of any of the foregoing, however, if either:

                  (i)      the Sale Price of the Common Stock of the Company for
         any five Trading Days within the 10 consecutive Trading Days ending
         immediately before the later of the Change in Control or the public
         announcement thereof equals or exceeds 105% of the Conversion Price of
         the Securities in effect immediately before the Change in Control or
         the public announcement thereof; or

                  (ii)     at least 90% of the consideration, excluding cash
         payments for fractional shares, in the transaction or transactions
         constituting the Change in Control consists of shares of capital stock
         traded on a national securities exchange or quoted on the Nasdaq
         National Market or which will be so traded or quoted when issued or
         exchanged in connection with a change in control (these securities

                                       38

<PAGE>

         being referred to as "publicly traded securities") and as a result of
         this transaction or transactions the Securities become convertible into
         such publicly traded securities, excluding cash payments for fractional
         shares.

                  For purposes of the above paragraph, the term capital stock of
any person means any and all shares (including ordinary shares or American
Depositary Shares), interests, participations or other equivalents however
designated of corporate stock or other equity participations, including
partnership interests, whether general or limited, of such person and any rights
(other than debt securities convertible or exchangeable into an equity
interest), warrants or options to acquire an equity interest in such person.

                  (b)      Change in Control Company Notice. Within 15 Business
Days after the occurrence of a Change in Control (the "Change in Control Notice
Date"), the Company shall mail a written notice of Change in Control (the
"Change in Control Company Notice") by first-class mail to the Trustee and to
each Holder (and to beneficial owners as required by applicable law). The notice
shall include a form of Change in Control Purchase Notice to be completed by the
Securityholder and shall state:

                  (1)      briefly, the events causing a Change in Control and
         the date of such Change in Control;

         specifying the percentage of each;

                  (6)      if the Company will pay the Change in Control
         Purchase Price (or a specified percentage thereof) with Common Stock,
         the method of calculating the Market Price of the Common Stock;

                  (7)      if the Company will pay the Change in Control
         Purchase Price with Common Stock, that because the Market Price of
         Common Stock will be determined prior to the Change in Control Purchase
         Date, Holders will bear the market risk with respect to the value of
         Common Stock to be received from the date such Market Price is
         determined to the Change in Control Purchase Date;

                  (8)      the name and address of the Paying Agent and the

         Agent to collect payment of the Change in Control Purchase Price;

                  (12)     that the Change in Control Purchase Price for any

         the Change in Control Purchase Date and the time of surrender of such
         Security as described in (11);

                  (13)     briefly, the procedures the Holder must follow to
         exercise rights under this Section 3.09;

                  (14)     briefly, the conversion rights of the Securities;

                  (15)     the procedures for withdrawing a Change in Control

                  (16)     that, unless the Company defaults in making payment

                  (c)      Change in Control Purchase Notice. A Holder may
exercise its rights specified in Section 3.09(a) upon satisfaction of the
following:

                  (1)      delivery of a written notice of purchase (a "Change
         in Control Purchase Notice") to the Paying Agent at any time prior to
         the close of business on the second business day prior to the Change in
         Control Purchase Date, stating:

                           (A)      if certificated Securities have been issued,
                  the certificate number of the Security which the Holder will
                  deliver to be purchased;

                           (B)      the portion of the principal amount of the

                  portion must be $1,000 or an integral multiple thereof;

                                       40

<PAGE>

                           (C)      that such Security shall be purchased
                  pursuant to the terms and conditions specified in paragraph 6
                  of the Securities and in this Indenture; and

                           (D)      in the event the Company elects, pursuant to
                  Section 3.09(f), to pay the Change in Control Purchase Price
                  to be paid as of such Change in Control Purchase Date, in
                  whole or in part, in shares of Common Stock but such portion
                  of the Change in Control Purchase Price shall ultimately be
                  payable to such Holder entirely in cash because any of the
                  conditions to payment of the Change in Control Purchase Price
                  in Common Stock, as set forth in Section 3.09(d), is not
                  satisfied prior to the close of business on such Change in
                  Control Purchase Date, whether such Holder elects (i) to
                  withdraw such Change in Control Purchase Notice as to some or
                  all of the Securities to which such Purchase Notice relates
                  (stating the principal amount and certificate numbers of the
                  Securities as to which such withdrawal shall relate), or (ii)
                  to receive cash in respect of the entire Change in Control
                  Purchase Price for all Securities (or portions thereof) to
                  which such Change in Control Purchase Notice relates; and

                  (2)      the delivery of such Security to the Paying Agent
         prior to, on or after the Change in Control Purchase Date (together
         with all necessary endorsements) at the offices of the Paying Agent,
         such delivery being a condition to the receipt by the Holder of the
         Change in Control Purchase Price therefor; provided, however, that such
         Change in Control Purchase Price shall be so paid pursuant to this
         Section 3.09 only if the Security so delivered to the Paying Agent
         shall conform in all respects to the description thereof set forth in
         the related Change in Control Purchase Notice, as determined by the
         Company.

                  If a Holder, in such Holder's Change in Control Purchase
Notice and in any written notice of withdrawal delivered by such Holder pursuant
to the terms of Section 3.10, fails to indicate such Holder's choice with
respect to the election set forth in clause (D) of Section 3.09(c)(1), such
Holder shall be deemed to have elected to receive cash in respect of the Change
in Control Purchase Price for all Securities subject to such Change in Control
Purchase Notice in the circumstances set forth in such clause (D).

                  The Company shall purchase from the Holder thereof, pursuant
to this Section 3.09, a portion of a Security if the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

                  Any purchase by the Company contemplated pursuant to the
provisions of this Section 3.09 shall be consummated by the delivery of the
consideration to be received by the Holder promptly following the later of the
Change in Control Purchase

                                       41

<PAGE>

Date and the time of delivery of the Security to the Paying Agent in accordance
with this Section 3.09.

                  Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Change in Control Purchase Notice
contemplated by this Section 3.09(c) shall have the right to withdraw such
Change in Control Purchase Notice at any time prior to the close of business on
the Business Day prior to the Change in Control Purchase Date by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section
3.10.

                  The Paying Agent shall promptly notify the Company of the
receipt by it of any Change in Control Purchase Notice or written withdrawal
thereof.

                  The Company shall not be required to comply with this Section
3.09 if a third party mails a written notice of Change in Control in the manner,
at the times and otherwise in compliance with this Section 3.09 and repurchases
all Securities for which a Change in Control Purchase Notice shall be delivered
and not withdrawn.

                  (d)      Company's Right to Elect Manner of Payment of Change
in Control Purchase Price. The Securities to be purchased pursuant to Section
3.09(a) may be paid for, at the election of the Company, in cash or Common
Stock, or in any combination of cash and Common Stock, subject to the conditions
set forth in Sections 3.09(e) and (f), as applicable. The Company shall
designate, in the Change in Control Company Notice delivered pursuant to Section
3.09(b), whether the Company will purchase the Securities for cash or Common
Stock, or, if a combination thereof, the percentages or amounts of the Change in
Control Purchase Price of Securities in respect of which it will pay in cash or
Common Stock; provided that the Company will pay cash for fractional interests
in Common Stock. For purposes of determining the existence of potential
fractional interests, all Securities subject to purchase by the Company held by
a Holder shall be considered together (no matter how many separate certificates
are to be presented). Each Holder whose Securities are purchased pursuant to
this Section 3.09 shall receive the same percentage of cash or Common Stock in
payment of the Change in Control Purchase Price for such Securities, except (i)
as provided in Section 3.09(f) with regard to the payment of cash in lieu of
fractional shares of Common Stock and (ii) in the event that the Company is
unable to purchase the Securities of a Holder or Holders of Common Stock because
any necessary qualifications or registrations of the Common Stock under
applicable state securities laws cannot be obtained, the Company may purchase
the Securities of such Holder or Holders for cash. The Company may not change
its election with respect to the consideration (or components or percentages of
components thereof) to be paid once the Company has given its Change in Control
Company Notice to Securityholders except pursuant to this Section 3.09 or
pursuant to Section 3.09(f) in the event of a failure to satisfy, prior to the
close of business on the

                                       42

<PAGE>

Purchase Date, any condition to the payment of the Purchase Price, in whole or
in part, in Common Stock.

                  At least three Business Days before the Change in Control
Company Notice Date, the Company shall deliver an Officers' Certificate to the
Trustee specifying:

                  (1)      the manner of payment selected by the Company,

                  (2)      the information required by this Section 3.09(b),

                  (3)      if the Company elects to pay the Change in Control
         Purchase Price, or a specified percentage thereof, in Common Stock,
         that the conditions to such manner of payment set forth in this Section
         3.09 have been or will be complied with, and

                  (4)      whether the Company desires the Trustee to give the
         Change in Control Company Notice required by Section 3.09(b).

                  (e)      Purchase with Cash. On each Change in Control
Purchase Date, at the option of the Company, the Change in Control Purchase
Price of Securities in respect of which a Change in Control Purchase Notice
pursuant to Section 3.09(c) has been given and not withdrawn, or a specified
percentage thereof, may be paid by the Company with cash equal to the aggregate
Change in Control Purchase Price of such Securities.

                  (f)      Payment by Issuance of Common Stock. On each Change
in Control Purchase Date, at the option of the Company, the Change in Control
Purchase Price of Securities in respect of which a Change in Control Purchase
Notice pursuant to Section 3.09(c) has been given, or a specified percentage
thereof, may be paid by the Company by the issuance of a number of shares of
Common Stock equal to the quotient obtained in dividing (i) the Change in
Control Purchase Price (less any amounts paid in cash) by (ii) 97 1/2% of the
Market Price of a share of Common Stock, subject to the next succeeding
paragraph.

                  The Company will not issue a fractional share of Common Stock
in payment of the Change in Control Purchase Price. Instead the Company will pay
cash for the current market value of the fractional share. The current market
value of a fraction of a share shall be determined by multiplying the Market
Price by such fraction and rounding the product to the nearest whole cent. It is
understood that if a Holder elects to have more than one Security purchased, the
number of shares of Common Stock shall be based on the aggregate amount of
Securities to be purchased.

                  Upon a payment by Common Stock pursuant to the terms hereof,
that portion of accrued and unpaid interest, if any, attributable to the period
from the Issue Date to the Change in Control Purchase Date with respect to the
purchased Security shall

                                       43

<PAGE>

not be cancelled, extinguished or forfeited but rather shall be deemed paid in
full to the Holder through the delivery of the Common Stock in exchange for the
Security being purchased pursuant to the terms hereof, and the fair market value
of such Common Stock (together with any cash payments in lieu of fractional
shares of Common Stock) shall be treated as issued, to the extent thereof, first
in exchange for the accrued and unpaid interest, if any, through the Change in
Control Purchase Date, and the balance, if any, of the fair market value of such
shares of Common Stock shall be treated as issued in exchange for the principal
amount of the Security being purchased pursuant to the provisions hereof.

                  The Company's right to exercise its election to purchase the
Securities pursuant to this Section 3.09 through the issuance of shares of
Common Stock shall be conditioned upon:

                  (1)      the Company's not having given its Change in Control
         Company Notice of an election to pay entirely in cash and its giving of
         timely Change in Control Company Notice of election to purchase all or
         a specified percentage of the Securities with Common Stock as provided
         herein;

                  (2)      the shares of Common Stock having been admitted for
         listing or admitted for listing subject to notice of issuance on the
         New York Stock Exchange or if the Common Stock is not then listed on
         the New York Stock Exchange, on such other United States securities
         exchange on which the Common Stock is then listed or, if the Common
         Stock is not then listed on a United States securities exchange, as
         quoted on the National Association of Securities Dealers Automated
         Quotation System;

                  (3)      the registration of the shares of Common Stock to be
         issued in respect of the payment of the Change in Control Purchase
         Price under the Securities Act or the Exchange Act, in each case, if
         required;

                  (4)      any necessary qualification or registration under
         applicable state securities laws or the availability of an exemption
         from such qualification and registration; and

                  (5)      the receipt by the Trustee of (A) an Officers'
         Certificate stating that the terms of the issuance of the Common Stock
         are in conformity with this Indenture and that conditions (1), (2), (3)
         and (4) above and the condition set forth in the second succeeding
         sentence have been satisfied and (B) an Opinion of Counsel to the
         effect that the shares of Common Stock to be issued by the Company in
         payment of the Change in Control Purchase Price in respect of
         Securities have been duly authorized and, when issued and delivered
         pursuant to the terms of this Indenture in payment of the Change in
         Control Purchase Price in

                                       44

<PAGE>

         respect of the Securities, will be validly issued, fully paid and
         non-assessable and, to the best of such counsel's knowledge, free from
         preemptive rights under applicable state law or material contracts,
         and, in the case of such Officers' Certificate, stating that conditions
         to the issuance of shares of Common Stock have been satisfied.

                  Such Officers' Certificate shall also set forth the number of
shares of Common Stock to be issued for each $1,000 principal amount of
Securities and the Sale Price of a share of Common Stock on each trading day
during the period for which the Market Price is calculated. The Company may pay
the Change in Control Purchase Price (or any portion thereof) in Common Stock
only if the information necessary to calculate the Market Price is published in
a daily newspaper of national circulation. If the foregoing conditions are not
satisfied with respect to a Holder or Holders prior to the close of business on
the Change in Control Purchase Date and the Company has elected to purchase the
Securities pursuant to this Section 3.09 through the issuance of shares of
Common Stock, the Company shall pay the entire Change in Control Purchase Price
of the Securities of such Holder or Holders in cash.

                  (g)      Taxes. If a Holder of a Security is paid in Common
Stock, the Company shall pay any documentary, stamp or similar issue or transfer
tax due on such issue of shares of Common Stock. However, the Holder shall pay
any such tax which is due because the Holder requests the shares of Common Stock
to be issued in a name other than the Holder's name. The Paying Agent may refuse
to deliver the certificates representing the Common Stock being issued in a name
other than the Holders' name until the Paying Agent receives a sum sufficient to
pay any tax which will be due because the shares of Common Stock are to be
issued in a name other than the Holder's name. Nothing herein shall preclude any
income tax withholding required by law or regulations.

                  SECTION 3.10      Effect of Purchase Notice or Change in
Control Purchase Notice. Upon receipt by the Paying Agent of the Purchase Notice
or Change in Control Purchase Notice specified in Section 3.08(a) or Section
3.09(c), as applicable, the Holder of the Security in respect of which such
Purchase Notice or Change in Control Purchase Notice, as the case may be, was
given shall (unless such Purchase Notice or Change in Control Purchase Notice is
withdrawn as specified in the following two paragraphs) thereafter be entitled
to receive solely the Purchase Price or Change in Control Purchase Price, as the
case may be, with respect to such Security. Such Purchase Price or Change in
Control Purchase Price shall be paid to such Holder, subject to receipt of funds
and/or securities by the Paying Agent, promptly following the later of (x) the
Purchase Date or the Change in Control Purchase Date, as the case may be, with
respect to such Security (provided the conditions in Section 3.08(a) or Section
3.09(c), as applicable, have been satisfied) and (y) the time of delivery of
such Security to the Paying Agent by the Holder thereof in the manner required
by Section 3.08(a) or Section 3.09(c), as applicable. Securities in respect of
which a Purchase Notice or

                                       45
<PAGE>

Change in Control Purchase Notice, as the case may be, has been given by the
Holder thereof may not be converted pursuant to Article 10 hereof on or after
the date of the delivery of such Purchase Notice or Change in Control Purchase
Notice, as the case may be, unless such Purchase Notice or Change in Control
Purchase Notice, as the case may be, has first been validly withdrawn as
specified in the following two paragraphs.

                  A Purchase Notice or Change in Control Purchase Notice, as the
case may be, may be withdrawn by means of a written notice of withdrawal
delivered to the office of the Paying Agent in accordance with the Purchase
Notice or Change in Control Purchase Notice, as the case may be, at any time
prior to the close of business on the Business Day prior to the Purchase Date or
the Change in Control Purchase Date, as the case may be, specifying:

                  (1)      if certificated Securities have been issued, the
         certificate number of the Security in respect of which such notice of
         withdrawal is being submitted,

                  (2)      the principal amount of the Security with respect to
         which such notice of withdrawal is being submitted, and

                  (3)      the principal amount, if any, of such Security which
         remains subject to the original Purchase Notice or Change in Control
         Purchase Notice, as the case may be, and which has been or will be
         delivered for purchase by the Company.

                  A written notice of withdrawal of a Purchase Notice or Change
in Control Purchase Notice may be in the form set forth in the preceding
paragraph or may be in the form of (i) a conditional withdrawal contained in a
Purchase Notice pursuant to the terms of Section 3.08(a)(1)(D) and Section
3.09(c)(1)(D) or (ii) a conditional withdrawal containing the information set
forth in Section 3.08(a)(1)(D) and Section 3.09(c)(1)(D) and the preceding
paragraph and contained in a written notice of withdrawal delivered to the
Paying Agent as set forth in the preceding paragraph.

                  There shall be no purchase of any Securities pursuant to
Section 3.08 or 3.09 (other than through the issuance of Common Stock in payment
of the Purchase Price or Change in Control Purchase Price, as the case may be,
including cash in lieu of fractional shares) if there has occurred (prior to, on
or after, as the case may be, the giving, by the Holders of such Securities, of
the required Purchase Notice or Change in Control Purchase Notice, as the case
may be) and is continuing an Event of Default (other than a default in the
payment of the Purchase Price or Change in Control Purchase Price, as the case
may be, with respect to such Securities). The Paying Agent will promptly return
to the respective Holders thereof any Securities (x) with respect to which a
Purchase Notice or Change in Control Purchase Notice, as the case may be, has
been withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of

                                       46
<PAGE>

an Event of Default (other than a default in the payment of the
Purchase Price or Change in Control Purchase Price, as the case may be, and any
accrued and unpaid interest with respect to such Securities) in which case, upon
such return, the Purchase Notice or Change in Control Purchase Notice with
respect thereto shall be deemed to have been withdrawn.

                  SECTION 3.11 Deposit of Purchase Price or Change in Control
Purchase Price. Prior to 11:30 a.m., New York City time, on the Business Day
following the Purchase Date or the Change in Control Purchase Date, as the case
may be, the Company shall deposit with the Trustee or with the Paying Agent (or,
if the Company or a Subsidiary or an Affiliate of either of them is acting as
the Paying Agent, shall segregate and hold in trust as provided in Section 2.04)
an amount of money (in immediately available funds if deposited on such Business
Day) or Common Stock, if permitted hereunder, sufficient to pay the aggregate
Purchase Price or Change in Control Purchase Price, as the case may be, of all
the Securities or portions thereof which are to be purchased as of the Purchase
Date or Change in Control Purchase Date, as the case may be. If the Paying Agent
holds money or Common Stock sufficient to pay the Purchase Price or Change in
Control Purchase Price, as applicable, of such Security or portion thereof on
the Business Day following the Purchase Date or Change in Control Purchase Date,
as applicable, in accordance with the terms of the Indenture, then at the close
of business on the Purchase Date or Change in Control Purchase Date, as
applicable, such Security or portion thereof will cease to be outstanding and
interest on such Security or portion thereof will cease to accrue, whether or
not such Security or portion thereof is delivered to the Paying Agent.
Thereafter, all other rights of the Holder shall terminate, other than the right
to receive the Purchase Price or Change in Control Purchase Price upon delivery
of such Security.

                  SECTION 3.12 Securities Purchased in Part. Any Security which
is to be purchased only in part shall be surrendered at the office of the Paying
Agent (with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge,
a new Security or Securities, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to, and in exchange for, the
portion of the principal amount of the Security so surrendered which is not
purchased.

                                       47
<PAGE>

                  SECTION 3.13 Repayment to the Company. The Trustee and the
Paying Agent shall promptly return to the Company any cash or shares of Common
Stock that remain unclaimed as provided in paragraph 13 of the Securities,
together with interest or dividends, if any, thereon (subject to the provisions
of Section 7.01(f)), held by them for the payment of the Purchase Price or
Change in Control Purchase Price, as the case may be; provided, however, that to
the extent that the aggregate amount of cash or shares of Common Stock deposited
by the Company pursuant to Section 3.11 exceeds the aggregate Purchase Price or
Change in Control Purchase Price, as the case may be, of the Securities or
portions thereof which the Company is obligated to purchase as of the Purchase
Date or Change in Control Purchase Date, as the case may be, whether as a result
of withdrawal or otherwise, then promptly after the Business Day following the
Purchase Date or Change in Control Purchase Date, as the case may be, the
Trustee shall return any such excess to the Company together with interest or
dividends, if any, thereon (subject to the provisions of Section 7.01(f)).

                  SECTION 3.14 Termination of Right to Pay in Common Stock.
Notwithstanding anything to the contrary in the Securities or the Indenture or
otherwise, the Company in its sole discretion may elect to terminate its right
to pay in Common Stock, in whole or in part, with respect to any purchase,
repurchase or redemption of any Security (or portion thereof) by providing a
notice to the Trustee of such election.

                                   ARTICLE 4

                                   COVENANTS

                  SECTION 4.01 Payment of Securities. The Company shall promptly
make all payments in respect of the Securities on the dates and in the manner
provided in the Securities or pursuant to this Indenture. Any amounts to be
given to the Trustee or Paying Agent, shall be deposited with the Trustee or
Paying Agent by 11:30 a.m., New York City time on the payment date, by the
Company. Principal, interest, Redemption Price, Purchase Price and Change in
Control Purchase Price shall be considered paid on the applicable date due if on
such date (or, in the case of a Purchase Price or Change in Control Purchase
Price, on the Business Day following the applicable Purchase Date or Change in
Control Purchase Date, as the case may be) the Trustee or the Paying Agent
holds, in accordance with this Indenture, money or securities, if permitted
hereunder, sufficient to pay all such amounts then due.

                  The Company shall, to the extent permitted by law, pay
interest on overdue amounts at the rate per annum set forth in paragraph 1 of
the Securities, compounded semiannually, which interest shall accrue from the
date such overdue amount was originally due to the date payment of such amount,
including interest thereon, has been made or duly provided for. All such
interest shall be payable on demand.

                  SECTION 4.02 SEC and Other Reports. The Company shall deliver
to the Trustee, within 30 days after it files the same with the SEC, copies of
its annual report and of the information, documents and other reports (or copies
of such portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act. The Company also shall comply with the
provisions of TIA Section 314(a). Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee's
receipt of the same shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

                  SECTION 4.03 Compliance Certificate. The Company shall deliver
to the Trustee within 120 days after the end of each calendar year of the
Company (beginning with the calendar year ending on December 31, 2003) an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company 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
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

                  SECTION 4.04 Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purposes of this Indenture.

                  SECTION 4.05 Maintenance of Office or Agency. The Company will
maintain in the Borough of Manhattan, The City of New York, an office or agency
of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities
may be presented or surrendered for payment, where Securities may be surrendered
for registration of transfer, exchange, purchase, redemption or conversion and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The Company shall give prompt written notice
to the Trustee of the location, and of any change in the location, of any such
office or agency (other than a change in the location of the office of the
Trustee). If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 13.02.

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its

                                       49
<PAGE>

obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such purposes.

                  SECTION 4.06 Delivery of Certain Information. At any time when
the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the
request of a Holder or any beneficial holder of Securities or shares of Common
Stock which are restricted securities issued upon conversion thereof, the
Company will promptly furnish or cause to be furnished Rule 144A Information (as
defined below) to such Holder or any beneficial holder of Securities or holder
of shares of Common Stock issued upon conversion of Securities, or to a
prospective purchaser of any such security designated by any such holder, as the
case may be, to the extent required to permit compliance by such Holder or
holder with Rule 144A under the Securities Act in connection with the resale of
any such security. "Rule 144A Information" shall be such information as is
specified pursuant to Rule 144A(d)(4) under the Securities Act.

                  SECTION 4.07 Covenant to Comply with Securities Laws upon
Purchase of Securities. In connection with any offer to purchase or purchase of
Securities under Section 3.08 or 3.09 hereof (provided that such offer or
purchase constitutes an "Issuer Tender Offer" for purposes of Rule 13e-4 (which
term, as used herein, includes any successor provision thereto) under the
Exchange Act at the time of such offer or purchase), the Company shall to the
extent applicable (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange
Act, (ii) file the related Schedule TO (or any successor schedule, form or
report) under the Exchange Act, and (iii) otherwise comply with all Federal and
state securities laws so as to permit the rights and obligations under Sections
3.08 and 3.09 to be exercised in the time and in the manner specified in
Sections 3.08 and 3.09.

                                    ARTICLE 5

                              SUCCESSOR CORPORATION

                  SECTION 5.01 Consolidation, Merger or Sale of Assets
Permitted. The Company covenants that it will not merge or consolidate with or
into any other Person or sell, convey, transfer or otherwise dispose of all or
substantially all of its assets to any Person, unless:

                  (a)      the successor (if other than the Company) formed by
         such consolidation or into which the Company is merged or to which all
         or substantially all of the assets of the Company are sold, conveyed or
         transferred (A) shall be a Person organized and existing under the laws
         of the United States of America, any state thereof or the District of
         Columbia, and (B) shall expressly assume by supplemental indenture
         executed and delivered to the Trustee the due and punctual payment of
         all amounts with respect to the Securities, according to

                                       50
<PAGE>

         their tenor, and the due and punctual performance and observance of all
         of the covenants and obligations of the Company under the Securities
         and this Indenture; and

                  (b)      immediately after giving effect to such transaction,
         no Default or Event of Default shall have occurred and be continuing;
         and

                  (c)      the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger, sale, conveyance, transfer and, if a
         supplemental indenture is required under clause (a)(B) above in
         connection with such transaction, such supplemental indenture, comply
         with this Article 5 and that all conditions precedent herein provided
         for relating to such transaction have been satisfied.

                  SECTION 5.02 Succession by Successor Corporation. In case of
any such merger, consolidation, sale, conveyance or other disposition and upon
any such assumption of the obligations of the Company by a successor as provided
in Section 5.01, such successor shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture and the
Securities with the same effect as if such successor had been named as the
Company herein; and thereafter, the Company shall be discharged from all
obligations and covenants under this Indenture and the Securities. Subject to
Section 9.06, the Company, the Guarantor, the Trustee and the successor Person
shall enter into a supplemental indenture to evidence the succession and
substitution of such successor Person and such discharge and release of the
Company.

                  SECTION 5.03 Evidence to be Furnished Trustee. The Trustee may
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale or conveyance, and any such
assumption, complies with the provisions of this Article 5.

                  SECTION 5.04 Merger or Consolidation of Guarantor. The
Guarantor shall not consolidate with or merge into any Person or sell, convey,
or transfer its properties and assets substantially as an entirety to another
Person unless the surviving Person assumes the obligation of the Guarantor and
the surviving Person is organized and existing under the laws of the United
States, any state thereof or the District of Columbia. In the event of the
assumption by a successor Person of the obligations of the Guarantor as provided
in the immediately preceding sentence, such successor Person shall succeed to
and be substituted for the Guarantor hereunder and under the Guarantee and all
obligations of the Guarantor under the Indenture and the Guarantee shall
terminate.

                             DEFAULTS AND REMEDIES

                  SECTION 6.01 Events of Default. An "Event of Default" occurs
if:

                  (1)      the Company defaults in payment of any interest when
         due under the Securities and such default continues for 30 days;

                  (2)      the Company defaults in the payment of the principal
         amount at the Stated Maturity, Redemption Price, Purchase Price or
         Change in Control Purchase Price on any Security, in each case when the
         same becomes due and payable;

                  (3)      the Company fails to comply with any of its
         agreements in the Securities or this Indenture (other than those
         referred to in clauses (1) and (2) above) and the Company fails to cure
         (or obtain a waiver of) such failure for 60 days after receipt by the
         Company of a Notice of Default as set forth in the last paragraph of
         this Section 6.01;

                  (4)      default by the Company or the Guarantor with respect
         to any Debt, whether such Debt now exists or is created later, which
         default results in such Debt becoming or being declared due and payable
         prior to the date on which it would otherwise have become due and
         payable, and the aggregate principal amount of such Debt so accelerated
         exceeds $50,000,000, and such acceleration has not been rescinded or
         annulled within a period of 10 days after receipt by the Company of a
         Notice of Default as set forth in the last paragraph of this Section
         6.01; provided, however, that if any such default shall be cured,
         waived, rescinded or annulled, then the Event of Default by reason
         thereof shall be deemed not to have occurred;

                  (5)      the Guarantee ceases to be in full force and effect
         or is declared null and void or the Guarantor denies that it has any
         further liability under the Guarantee, or gives notice to such effect
         (other than by reason of the termination of this Indenture or the
         release of any such Guarantee in accordance with this Indenture) and
         such condition shall have continued for a period of 30 days after
         written notice of such failure requiring the Guarantor and the Company
         to remedy the same shall have been given (x) to the Company by the
         Trustee or (y) to the Company and the Trustee by the holders of 25% in
         aggregate principal amount of the Securities then outstanding;

                  (6)      the Company or the Guarantor pursuant to or under or
         within the meaning of any Bankruptcy Law:

                                       52
<PAGE>

                           (A)      commences a voluntary case or proceeding;

                           (B)      consents to the entry of an order for relief
                  against it in an involuntary case or proceeding or the
                  commencement of any case against it;

                           (C)      consents to the appointment of a Custodian
                  of it or for all or substantially all of its property; or

                           (D)      makes a general assignment for the benefit
                  of its creditors.

                  (7)      a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (A)      is for relief against the Company or the
                  Guarantor in an involuntary case or proceeding, or adjudicates
                  the Company or the Guarantor insolvent or bankrupt;

                           (B)      appoints a Custodian of the Company or the
                  Guarantor or for all or substantially all of its respective
                  property; or

                           (C)      orders the winding up or liquidation of the
                  Company or the Guarantor;

         and the order or decree remains unstayed and in effect for 90 days.

                  "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors.

                  "Custodian" means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law.

                  A Default under clause (3) or clause (4) above is not an Event
of Default until the Trustee notifies the Company, or the Holders of at least
25% in aggregate principal amount of the Securities at the time outstanding
notify the Company and the Trustee, of the Default and the Company does not cure
such Default (and such Default is not waived) within the time specified in
clause (3) or clause (4) above after actual receipt of such notice. Any such
notice must specify the Default, demand that it be remedied and state that such
notice is a "Notice of Default".

                  SECTION 6.02 Acceleration. If an Event of Default (other than
an Event of Default specified in Section 6.01(6) or (7) in respect of the
Company or the Guarantor) occurs and is continuing, either the Trustee by
written notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities at the time

                                       53
<PAGE>

outstanding by notice to the Company and the Trustee, may declare the principal
amount and all accrued and unpaid interest, if any, through the date of
declaration on all the Securities to be immediately due and payable. Upon such a
declaration, such principal amount, and such accrued and unpaid interest, if
any, shall be due and payable immediately. If an Event of Default specified in
Section 6.01(6) or (7) occurs in respect of the Company or the Guarantor and is
continuing, the principal amount, and accrued and unpaid interest, if any, on
all the Securities shall become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Securityholders. The
Holders of a majority in aggregate principal amount of the Securities at the
time outstanding, by notice to the Trustee (and without notice to any other
Securityholder), may rescind any acceleration of the Securities and its
consequences if the rescission would not conflict with any judgment or decree of
any court of competent jurisdiction and if all existing Events of Default have
been cured or waived except nonpayment of the principal amount, and accrued and
unpaid interest, if any, that have become due solely as a result of acceleration
and if all amounts due to the Trustee under Section 7.07 have been paid. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.

                  SECTION 6.03 Other Remedies. If an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy to collect the
payment of the principal amount, and accrued and unpaid interest, if any, on the
Securities or to enforce the performance of any provision of the Securities or
this Indenture.

                  The Trustee may maintain a proceeding even if the Trustee does
not possess any of the Securities or does not produce any of the Securities in
the proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default. Except as set forth in Section 2.07 hereof, no remedy is
exclusive of any other remedy. To the extent permitted by applicable law, all
available remedies are cumulative.

                  SECTION 6.04 Waiver of Past Defaults. Subject to Section 6.02,
the Holders of a majority in aggregate principal amount of the Securities at the
time outstanding, by notice to the Trustee (and without notice to any other
Securityholder), may waive an existing Default and its consequences except (1)
an Event of Default described in Section 6.01(1) or (2), (2) a Default in
respect of a provision that under Section 9.02 cannot be amended without the
consent of each Securityholder affected or (3) a Default which constitutes a
failure to convert any Security in accordance with the terms of Article 10. When
a Default is waived, it is deemed cured and shall cease to exist, but no such
waiver shall extend to any subsequent or other Default or impair any consequent
right. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and
such Section 316(a)(1)(B) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

                                       54
<PAGE>

                  SECTION 6.05 Control by Majority. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding may direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture or that the Trustee determines in good faith is unduly
prejudicial to the rights of other Securityholders or would involve the Trustee
in personal liability unless the Trustee is offered indemnity satisfactory to
it. This Section 6.05 shall be in lieu of Section 316(a)(1)(A) of the TIA and
such Section 316(a)(1)(A) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

                  SECTION 6.06 Limitation on Suits. A Securityholder may not
pursue any remedy with respect to this Indenture or the Securities unless:

                  (1)      the Holder gives to the Trustee written notice
         stating that an Event of Default is continuing;

                  (2)      the Holders of at least 25% in aggregate principal
         amount of the Securities at the time outstanding make a written request
         to the Trustee to pursue the remedy;

                  (3)      such Holder or Holders offer to the Trustee security
         or indemnity satisfactory to the Trustee against any loss, liability or
         expense;

                  (4)      the Trustee does not comply with the request within
         60 days after receipt of such notice, request and offer of security or
         indemnity; and

                  (5)      the Holders of a majority in aggregate principal
         amount of the Securities at the time outstanding do not give the
         Trustee a direction inconsistent with the request during such 60-day
         period.

                  A Securityholder may not use this Indenture to prejudice the
rights of any other Securityholder or to obtain a preference or priority over
any other Securityholder.

                  SECTION 6.07 Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of the principal, interest, Redemption Price, Purchase Price
or Change in Control Purchase Price in respect of the Securities held by such
Holder, on or after the respective due dates expressed in the Securities or any
Redemption Date, and to convert the Securities in accordance with Article 10, or
to bring suit for the enforcement of any such payment on or after such
respective dates or the right to convert, shall not be impaired or affected
adversely without the consent of such Holder.

                                       55
<PAGE>

                  SECTION 6.08 Collection Suit by Trustee. If an Event of
Default described in Section 6.01(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount owing with respect to the Securities
and the amounts provided for in Section 7.07.

                  SECTION 6.09 Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, to the
extent permitted by applicable law, the Trustee (irrespective of whether the
principal amount, interest, Redemption Price, Purchase Price or Change in
Control Purchase Price 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 on the Company for the payment of any such amount) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                  (a)      to file and prove a claim for the whole amount of the
         principal, interest, Redemption Price, Purchase Price or Change in
         Control Purchase Price, as the case may be, and to file such other
         papers or documents as may be necessary or advisable in order to have
         the claims of the Trustee (including any claim for the reasonable
         compensation, expenses, disbursements and advances of the Trustee, its
         agents and counsel or any other amounts due the Trustee under Section
         7.07) and of the Holders allowed in such judicial proceeding, and

                  (b)      to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

                  SECTION 6.10 Priorities. If the Trustee collects any money
pursuant to this Article 6, it shall pay out the money in the following order:

                                       56
<PAGE>

                  FIRST: to the Trustee for amounts due under Section 7.07;

                  SECOND: to Securityholders for amounts due and unpaid on the
         Securities for the principal, interest, Redemption Price, Purchase
         Price or Change in Control Purchase Price, as the case may be, ratably,
         without preference or priority of any kind, according to such amounts
         due and payable on the Securities; and

                  THIRD: the balance, if any, to the Company or, to the extent
         the Trustee has collected any amounts pursuant to the Guarantee from
         the Guarantor, to the Guarantor.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section 6.10. At least 15 days
before such record date, the Trustee shall mail to each Securityholder and the
Company a notice that states the record date, the payment date and the amount to
be paid.

                  SECTION 6.11 Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant (other than the Trustee)
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate
principal amount of the Securities at the time outstanding. This Section 6.11
shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby
expressly excluded from this Indenture, as permitted by the TIA.

                  SECTION 6.12 Waiver of Stay, Extension or Usury Laws. Each of
the Company and the Guarantor covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
or any usury or other law wherever enacted, now or at any time hereafter in
force, which would prohibit or forgive the Company or the Guarantor from paying
all or any portion of the principal, interest, Redemption Price, Purchase Price
or Change in Control Purchase Price, as contemplated herein, or which may affect
the covenants or the performance of this Indenture; and each of the Company and
the Guarantor (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

                                     TRUSTEE

                  SECTION 7.01 Duties of Trustee.

                  (a)      If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by
this Indenture and use the same degree of care and skill in its exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

                  (b)      Except during the continuance of an Event of Default:

                  (1)      the Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others; and

                  (2)      in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture, but in case of any such certificates or opinions which
         by any provision hereof are specifically required to be furnished to
         the Trustee, the Trustee shall examine the certificates and opinions to
         determine whether or not they conform to the requirements of this
         Indenture, but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein.

This Section 7.01(b) shall be in lieu of Section 315(a) of the TIA and such
Section 315(a) is hereby expressly excluded from this Indenture, as permitted by
the TIA.

                  (c)      The Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                  (1)      this paragraph (c) does not limit the effect of
         paragraph (b) of this Section 7.01;

                  (2)      the Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer unless it is
         proved that the Trustee was negligent in ascertaining the pertinent
         facts; and

                  (3)      the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05.

                                       58
<PAGE>

Subparagraphs (c)(1), (2) and (3) shall be in lieu of Sections 315(d)(1),
315(d)(2) and 315(d)(3) of the TIA and such Sections 315(d)(1), 315(d)(2) and
315(d)(3) are hereby expressly excluded from this Indenture, as permitted by the
TIA.

                  (d)      Every provision of this Indenture that in any way
relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this
Section 7.01.

                  (e)      The Trustee may refuse to perform any duty or
exercise any right or power or extend or risk its own funds or otherwise incur
any financial liability unless it receives indemnity satisfactory to it against
any loss, liability or expense.

                  (f)      Money held by the Trustee in trust hereunder need not
be segregated from other funds except to the extent required by law. The Trustee

any money received by it hereunder unless otherwise agreed in writing with the
Company.

                  SECTION 7.02 Rights of Trustee. Subject to its duties and
responsibilities under the provisions of Section 7.01, and, except as expressly
excluded from this Indenture pursuant to said Section 7.01, subject also to its
duties and responsibilities under the TIA:

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

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

                  (c)      the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or

         appointed with due care by it hereunder;

                  (d)      the Trustee shall not be liable for any action taken,
         suffered, or omitted to be taken by it in good faith which it believes
         to be authorized or within its rights or powers conferred under this
         Indenture;

                  (e)      the Trustee may consult with counsel selected by it
         and any advice or opinion of such counsel shall be full and complete
         authorization and protection

                                       59
<PAGE>

         in respect of any action taken or suffered or omitted by it hereunder
         in good faith and in accordance with such advice or opinion of such
         counsel;

                  (f)      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 Holders, pursuant to the
         provisions of this Indenture, unless such Holders shall have offered to
         the Trustee security or indemnity satisfactory to it against any costs,
         expenses and liabilities which may be incurred therein or thereby;

                  (g)      any request or direction of the Company mentioned
         herein may be sufficiently evidenced by a Company Request or Company
         Order and any resolution of the Board of Directors may be sufficiently
         evidenced by a resolution of the Board of Directors;

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

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

                  (j)      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 to each agent,
         custodian and other Person employed to act hereunder; and

                  (k)      the Trustee may request that the Company 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.

                  SECTION 7.03 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it

                                       60
<PAGE>

were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar
may do the same with like rights. However, the Trustee must comply with Sections
7.10 and 7.11.

                  SECTION 7.04 Trustee's Disclaimer. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the
Securities, it shall not be accountable for the Company's use or application of
the proceeds from the Securities, it shall not be responsible for any statement
in the registration statement for the Securities under the Securities Act or in
the Indenture or the Securities (other than its certificate of authentication),
or the determination as to which beneficial owners are entitled to receive any
notices hereunder.

                  SECTION 7.05 Notice of Defaults. If a Default or Event of
Default occurs and is continuing and if it is known to a Responsible Officer of
the Trustee, the Trustee shall give to each Securityholder notice of the Default
or Event of Default, as applicable, within 90 days after such Responsible
Officer obtains knowledge of such Default or Event of Default, as applicable,
unless such Default or Event of Default, as applicable, shall have been cured or
waived before the giving of such notice. Except in the case of a Default or
Event of Default, as applicable, described in Section 6.01(1) or (2), the
Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of Securityholders. The second sentence of this Section 7.05 shall be
in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby
expressly excluded from this Indenture, as permitted by the TIA. The Trustee
shall not be deemed to have knowledge of a Default unless a Responsible Officer
of the Trustee has received written notice of such Default.

                  SECTION 7.06 Reports by Trustee to Holders. Within 60 days
after each May 15 beginning with the May 15 following the date of this
Indenture, the Trustee shall mail to each Securityholder a brief report dated as
of such May 15 that complies with TIA Section 313(a), if required to do so by
such Section 313(a). The Trustee also shall comply with TIA Section 313(b).

                  A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each securities exchange, if
any, on which the Securities are listed. The Company agrees to promptly notify
the Trustee whenever the Securities become listed on any securities exchange and
of any delisting thereof.

                  SECTION 7.07 Compensation and Indemnity. The Company agrees:

                  (a)      to pay to the Trustee from time to time such
         reasonable compensation as the Company and the Trustee shall from time
         to time agree in writing for all services rendered by it hereunder
         (which compensation shall not be

                                       61
<PAGE>

         limited (to the extent permitted by law) by any provision of law in
         regard to the compensation of a trustee of an express trust);

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

                  (c)      to indemnify the Trustee or any predecessor, Trustee
         and their agents for, and to hold them harmless against, any loss,
         damage, claim, liability, cost or expense (including reasonable
         attorney's fees and expenses and taxes (other than taxes based upon,
         measured by or determined by the income of the Trustee)) incurred
         without negligence or bad faith on its part, arising out of or in
         connection with the acceptance or administration of this trust,
         including the reasonable costs and expenses of defending itself against
         any claim (whether asserted by any Holder or any other Person (other
         than the Company)) or liability in connection with the exercise or
         performance of any of its powers or duties hereunder.

                  To secure the Company's payment obligations in this Section
7.07, the Holders shall have been deemed to have granted to the Trustee a lien
prior to the Securities on all money or property held or collected by the
Trustee, except that held in trust to pay the principal, interest, Redemption
Price, Purchase Price or Change in Control Purchase Price, as the case may be,
on particular Securities.

                  The Company's payment obligations pursuant to this Section
7.07 shall survive the discharge of this Indenture and the resignation or
removal of the Trustee. When the Trustee incurs expenses after the occurrence of
a Default specified in Section 6.01(6) or(7), the expenses including the
reasonable charges and expenses of its counsel, are intended to constitute
expenses of administration under any Bankruptcy Law.

                  SECTION 7.08 Replacement of Trustee. The Trustee may resign by
so notifying the Company; provided, however, no such resignation shall be
effective until a successor Trustee has accepted its appointment pursuant to
this Section 7.08. The Holders of a majority in aggregate principal amount of
the Securities at the time outstanding may remove the Trustee by so notifying
the Trustee and the Company. The Company shall remove the Trustee if:

                  (a)      the Trustee fails to comply with Section 7.10;

                                       62
<PAGE>

                  (b)      the Trustee is adjudged bankrupt or insolvent;

                  (c)      a receiver or public officer takes charge of the
         Trustee or its property; or

                  (d)      the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint, by
resolution of its Board of Directors, a successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company satisfactory in form and
substance to the retiring Trustee and the Company. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held
by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07.

                  If a successor Trustee does not take office within 30 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of a majority in aggregate principal amount of the
Securities at the time outstanding may petition any court of competent
jurisdiction at the expense of the Company for the appointment of a successor
Trustee.

                  If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

                  SECTION 7.09 Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another Person, the resulting,
surviving or transferee Person without any further act shall be the successor
Trustee.

                  SECTION 7.10 Eligibility; Disqualification. The Trustee shall
at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The
Trustee (or its parent holding company) shall have a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual
report of condition. Nothing herein contained shall prevent the Trustee from
filing with the Commission the application referred to in the penultimate
paragraph of TIA Section 310(b).

                  SECTION 7.11 Preferential Collection of Claims Against
Company. The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship

                                       63
<PAGE>

listed in TIA Section 311(b). A Trustee who has resigned or been removed shall
be subject to TIA Section 311(a) to the extent indicated therein.

                                   ARTICLE 8

                             DISCHARGE OF INDENTURE

                  SECTION 8.01 Discharge of Liability on Securities. When (i)
the Company delivers to the Trustee all outstanding Securities (other than
Securities replaced pursuant to Section 2.07) for cancellation or (ii) all
outstanding Securities have become due and payable and the Company or the
Guarantor irrevocably deposits with the Trustee, the Paying Agent (if the Paying
Agent is not the Company or any of its Affiliates) or the Conversion Agent cash
or, if expressly permitted by the terms of the Securities or the Indenture,
Common Stock sufficient to pay all amounts due and owing on all outstanding
Securities (other than Securities replaced pursuant to Section 2.07), and if in
either case the Company or the Guarantor pays all other sums payable hereunder
by the Company, then this Indenture shall, subject to Section 7.07, cease to be
of further effect. The Trustee shall join in the execution of a document
prepared by the Company acknowledging satisfaction and discharge of this
Indenture on demand of the Company accompanied by an Officers' Certificate and
Opinion of Counsel and at the cost and expense of the Company.

                  SECTION 8.02 Repayment to the Company or the Guarantor. The
Trustee, the Paying Agent and the Conversion Agent shall return to the Company,
or to the extent the Trustee collects any amount pursuant to the Guarantee from
the Guarantor, to the Guarantor upon written request any money or securities
held by them for the payment of any amount with respect to the Securities that
remains unclaimed for two years, subject to applicable unclaimed property law.
After return to the Company or the Guarantor, as the case may be, Holders
entitled to the money or securities must look to the Company or the Guarantor
for payment as general creditors unless an applicable abandoned property law
designates another person and the Trustee, the Paying Agent and the Conversion
Agent shall have no further liability to the Securityholders with respect to
such money or securities for that period commencing after the return thereof.

Guarantor and the Trustee may amend this Indenture or the Securities without the
consent of any Securityholder:

<PAGE>

                  (1)      to cure any ambiguity, omission, defect or
         inconsistency in the Securities or this Indenture;

                  (2)      to evidence a successor to the Company or the
         Guarantor, and the assumption by that successor of the Company's or the
         Guarantor's obligations under the Indenture, the Securities or the
         Guarantee, as applicable, or otherwise to comply with Article 5 or
         Section 10.14;

                  (3)      to secure the Company's obligations under the
         Securities and this Indenture;

                  (4)      to add any additional Events of Default;

                  (5)      to increase the Conversion Rate;

         amendment thereto, or to comply with any requirement of the SEC in
         connection with the qualification of the Indenture under the TIA, or as
         necessary in connection with the registration of the Securities and the
         shares of Common Stock issuable upon conversion of the Securities under
         the Securities Act;

                  (8)      to make any change that does not materially adversely
         affect the rights of any Holders (it being understood that any
         amendment described in clause (1) above made solely to conform this
         Indenture to the final offering memorandum provided to investors in
         connection with the initial offering of the Securities will be deemed
         not to materially adversely affect the rights or interests of Holders);

                  (9)      to add or change any provisions to such extent as is

         appointment under this Indenture of separate or successor Trustees;

                  (11)     to make any change that would provide any additional
         rights or benefits to Securityholders; or

                  (12)     to modify the restrictions on, and procedures for,
         resale and other transfers of the Securities or the shares of Common
         Stock issuable upon conversion of the Securities pursuant to law,

         securities generally.

                  SECTION 9.02 With Consent of Holders. With the written consent
of the Holders of at least a majority in aggregate principal amount of the
Securities at the time outstanding, the Company, the Guarantor and the Trustee
may amend this Indenture or the Securities. However, without the consent of each
Securityholder affected, an amendment to this Indenture or the Securities may
not:

                  (1)      reduce the percentage in principal amount of
         Securities whose Holders must consent to an amendment or modification
         of this Indenture, waiver of compliance with certain provisions of this
         Indenture or waiver of Defaults;

                  (2)      alter the rate or manner of calculation of interest
         referred to in Article 11 and paragraph 1 of the Securities or alter
         the time of payment of interest on any Security;

                  (3)      reduce the principal amount with respect to any
         Security, or change the Stated Maturity of any Security;

                  (4)      reduce the Redemption Price, Purchase Price or Change
         in Control Purchase Price of any Security;

                  (5)      make any Security payable in money or securities
         other than as stated in the Security;

                  (6)      make any change to this Section 9.02;

                  (7)      make any change that adversely affects the right of a
         Securityholder to convert any Security;

                  (8)      make any change that adversely affects the right of a
         Securityholder to require the Company to purchase the Securities in
         accordance with the terms thereof and of this Indenture;

                  (9)      impair the right to institute suit for the
         enforcement of any payment with respect to the Securities or under the
         Guarantee of the Guarantor, or with respect to the conversion of the
         Securities; or

                  (10)     release the Guarantor from any of its obligations
         under its Guarantee other than in accordance with the terms of this
         Indenture.

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

                                       66
<PAGE>

                  After an amendment under this Section 9.02 becomes effective,
the Company shall mail to each Holder a notice briefly describing the amendment.

                  SECTION 9.03 Compliance with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall comply with the
TIA.

                  SECTION 9.04 Revocation and Effect of Consents, Waivers and
Actions. Until an amendment, consent, waiver or other action by Holders becomes
effective, a consent thereto by a Holder of a Security hereunder is a continuing
consent by the Holder and every subsequent Holder of that Security or portion of
the Security that evidences the same obligation as the consenting Holder's
Security, even if notation of the amendment, consent, waiver or other action is
not made on the Security. However, any such Holder or subsequent Holder may
revoke the consent as to such Holder's Security or portion of the Security if
the Trustee receives the notice of revocation before the date as of which the
amendment, consent, waiver or action is made effective. After an amendment,
consent, waiver or action becomes effective, it shall bind every Securityholder.

                  SECTION 9.05 Notation on or Exchange of Securities. Securities
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a
notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Securities so
modified as to conform, as confirmed in a Company Order, to any such
supplemental indenture may be prepared and executed by the Company and, if so
prepared and executed, shall be authenticated and delivered by the Trustee in
exchange for outstanding Securities.

                  SECTION 9.06 Trustee to Sign Supplemental Indentures. The
Trustee shall sign any supplemental indenture authorized pursuant to this
Article 9 if the amendment contained therein does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign such supplemental indenture. In signing such
supplemental indenture the Trustee shall receive, and (subject to the provisions
of Section 7.01) shall be fully protected in relying upon, in addition to the
documents required by Section 13.04, an Officers' Certificate and an Opinion of
Counsel stating that such amendment is authorized or permitted by this
Indenture.

                  SECTION 9.07 Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby.

                                   ARTICLE 10

                                   CONVERSION

                  SECTION 10.01 Conversion Privilege. A Holder of a Security may
convert such Security into Common Stock at any time during the periods and
subject to the conditions stated in paragraph 8 of the Securities, subject to
the provisions of this Article 10. The number of shares of Common Stock issuable
upon conversion of a Security per $1,000 of principal amount thereof (the
"Conversion Rate") shall be determined in accordance with the provisions of
paragraph 8 of the Securities. The initial number of shares of Common Stock
issuable upon conversion of a Security per $1,000 of principal amount thereof
shall equal 57.61, subject to adjustment.

                  A Holder may convert a portion of the principal amount of a
Security if the portion is $1,000 or an integral multiple of $1,000. Provisions
of this Indenture that apply to conversion of all of a Security also apply to
conversion of a portion of a Security.

                  The Trustee (or other Conversion Agent appointed by the
Company) shall, on behalf of the Company, determine on a daily basis whether the
Securities shall be convertible as a result of the occurrence of an event
specified in paragraph 8 of the Securities and, if the Securities shall be
convertible, the Trustee (or other Conversion Agent appointed by the Company)
shall promptly deliver to the Company and the Trustee (if the Trustee is not the
Conversion Agent) written notice thereof. Whenever the Securities shall become
convertible pursuant to the foregoing condition, the Company or, at the
Company's request, the Trustee in the name and at the expense of the Company,
shall promptly notify the Holders of the event triggering such convertibility in
the manner provided under the Indenture, and the Company shall use its
reasonable best efforts to publish such information on the Company's website and
publicly announce such information through Dow Jones & Company, Inc. or
Bloomberg Business News. Any notice so given shall be conclusively presumed to
have been duly given, whether or not the Holder receives such notice.

                  SECTION 10.02 Conversion Procedure. To convert a Security, a
Holder must satisfy the requirements in paragraph 8 of the Securities. The date
on which the Holder satisfies all those requirements is the conversion date (the
"Conversion Date").

                  Subject to and in accordance with Section 10.20, the Company
shall deliver to the Holder, through the Conversion Agent, a certificate for the
number of full shares of Common Stock issuable upon the conversion and cash in
lieu of any fractional share determined pursuant to Section 10.03. The Company
shall determine the number of shares and the amounts of cash (including with
respect to any fractional share)

                                       68
<PAGE>

determined as described in Section 10.03 and 10.20 and shall set forth such
information in an Officers' Certificate delivered to the Conversion Agent. The
Conversion Agent shall have no duties under this paragraph unless and until it
has received such certificate.

                  The person in whose name the certificate is registered shall
be treated as a stockholder of record on and after the Conversion Date;
provided, however, that no surrender of a Security on any date when the stock
transfer books of the Company shall be closed shall be effective to constitute
the Person or Persons entitled to receive the shares of Common Stock upon such
conversion as the record holder or holders of such shares of Common Stock on
such date, but such surrender shall be effective to constitute the Person or
Persons entitled to receive such shares of Common Stock as the record holder or
holders thereof for all purposes at the close of business on the next succeeding
day on which such stock transfer books are open; such conversion shall be at the
Conversion Rate in effect on the date that such Security shall have been
surrendered for conversion, as if the stock transfer books of the Company had
not been closed. Upon conversion of a Security, such Person shall no longer be a
Holder of such Security.

                  Holders may surrender a Security for conversion by means of a
book-entry delivery in accordance with paragraph 8 of the Security and the
regulations of the applicable book-entry facility.

                  No payment or adjustment will be made for dividends on, or
other distributions with respect to, any Common Stock except as provided in this
Article 10. On conversion of a Security, that portion of accrued and unpaid
interest, if any, attributable to the period from the Issue Date of the Security
through the Conversion Date with respect to the converted Security shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the Holder thereof through delivery of the Common Stock or cash, or
combination thereof (together with the cash payment, if any, in lieu of
fractional shares) in exchange for the Security being converted pursuant to the
provisions hereof; and the fair market value of such shares of Common Stock
(together with any such cash payment including cash in lieu of fractional
shares) shall be treated as issued, to the extent thereof, first in exchange for
the accrued and unpaid interest through the Conversion Date, and the balance, if
any, of such fair market value of such Common Stock (and any such cash payment)
shall be treated as issued in exchange for the principal amount of the Security
being converted pursuant to the provisions hereof.

                  If the Holder converts more than one Security at the same
time, the number of shares of Common Stock issuable upon the conversion shall be
based on the aggregate principal amount of the Securities converted.

                  Subject to the provisions of Article 10 and paragraph 8 of the
Securities, a Security surrendered for conversion based on (a) the Common Stock
price (in accordance with paragraph 8(a) of the Securities), may be surrendered
for conversion after

                                       69
<PAGE>

September 30, 2003 until the close of business on September 17, 2023, (b) the
Security being called for redemption (in accordance with paragraph 8(c) of the
Securities), may be surrendered for conversion at any time prior to the close of
business on the second Business Day immediately preceding the Redemption Date,
even if it is not otherwise convertible at such time, and (c) the occurrence of
certain corporate transactions (in accordance with paragraph 8(e) of the
Security) may be surrendered for conversion at any time from and after the date
which is 15 days prior to the anticipated effective date of such transaction
until 15 days after the actual date of such transaction, and if such day is not
a Business Day, the next occurring Business Day following such day.

                  Upon surrender of a Security that is converted in part, the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder, a new Security in an authorized denomination equal in principal amount
to the unconverted portion of the Security surrendered.

                  Securityholders of Securities surrendered for conversion
during the period from the close of business on any Regular Record Date next
preceding any Interest Payment Date to the opening of business of such Interest
Payment Date will receive the semiannual interest payable on such Securities on
the corresponding Interest Payment Date notwithstanding the conversion at any
time after the close of business on such Regular Record Date. Securities
surrendered for conversion by a Securityholder during the period from the close
of business on any Regular Record Date to the opening of business on the next
Interest Payment Date, except for Securities to be redeemed within this period,
must be accompanied by payment of an amount equal to the interest that the
Securityholder is to receive on the Securities so converted.

                  SECTION 10.03 Fractional Shares. The Company will not issue a
fractional share of Common Stock upon conversion of a Security. Instead, the
Company will deliver cash for the current market value of the fractional share.
The current market value of a fractional share shall be determined, to the
nearest 1/1,000th of a share, by multiplying the per share Sale Price of the
Common Stock, on the last Trading Day prior to the Conversion Date, by the
fractional amount and rounding the product to the nearest whole cent.

                  SECTION 10.04 Taxes on Conversion. If a Holder converts a
Security, the Company shall pay any documentary, stamp or similar issue or
transfer tax due on the issue of shares of Common Stock upon the conversion.
However, the Holder shall pay any such tax which is due because the Holder
requests the shares to be issued in a name other than the Holder's name. The
Conversion Agent may refuse to deliver the certificates representing the Common
Stock being issued in a name other than the Holder's name until the Conversion
Agent receives a sum sufficient to pay any tax which will be due because the
shares are to be issued in a name other than the Holder's name.

                                       70
<PAGE>

Nothing herein shall preclude the Company from any tax withholding or directing
the withholding of any tax required by law or regulations.

                  SECTION 10.05 Company to Provide Stock. The Company shall,
prior to issuance of any Securities under this Article 10, and from time to time
as may be necessary, reserve out of its authorized but unissued Common Stock a
sufficient number of shares of Common Stock to permit the conversion of the
Securities.

                  All shares of Common Stock delivered upon conversion of the
Securities shall be newly issued shares or treasury shares, shall be duly and
validly issued and fully paid and nonassessable and shall be free from
preemptive rights and free of any lien or adverse claim created by the Company.

                  The Company will endeavor promptly to comply with all federal
and state securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Securities, if any, and will list or cause to have
quoted such shares of Common Stock on the New York Stock Exchange or, if shares
of Common Stock are then not listed on the New York Stock Exchange, on such
other United States securities exchange or United States over-the-counter market
on which the Common Stock is then principally listed or quoted.

                  SECTION 10.06 Adjustment for Change in Capital Stock. Except
as set forth in Section 10.14, if, after the Issue Date of the Securities, the
Company:

                  (a)      pays a dividend or makes a distribution on its Common
         Stock in shares of its Common Stock;

                  (b)      subdivides its outstanding shares of Common Stock
         into a greater number of shares;

                  (c)      pays a dividend or makes a distribution on its Common
         Stock in shares of its Capital Stock (other than Common Stock or
         rights, warrants or options for its Capital Stock);

                  (d)      combines its outstanding shares of Common Stock into
         a smaller number of shares; or

                  (e)      issues by reclassification of its Common Stock any
         shares of its Capital Stock (other than rights, warrants or options for
         its Capital Stock),

then the conversion privilege and the Conversion Rate in effect immediately
prior to such action shall be adjusted so that the Holder of a Security
thereafter converted may receive the number of shares or other units of Capital
Stock of the Company which such Holder

                                       71

<PAGE>

would have owned immediately following such action if such Holder had converted
the Security immediately prior to such action.

                  The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.

                  SECTION 10.07 Adjustment for Rights Issue. Except as set forth
in Sections 10.14 and 10.19, if after the Issue Date of the Securities, the
Company distributes any rights, warrants or options to all holders of its Common
Stock entitling them, for a period expiring within 60 days after the record date
for such distribution, to purchase shares of Common Stock at a price per share
less than the Sale Price of the Common Stock as of the Time of Determination,
the Conversion Rate shall be adjusted in accordance with the formula below;
provided that if such rights are exercisable only upon the occurrence of a
triggering event, then the Conversion Rate will not be adjusted until such
triggering event occurs:

                                       R (O + N)
                               R' = ---------------
                                    O + [(N x P)/M]
                  where:

                  R' = the adjusted Conversion Rate.

                  R = the current Conversion Rate.

                  O = the number of shares of Common Stock outstanding on the
record date for the distribution to which this Section 10.07 is being applied.

                  N = the number of additional shares of Common Stock offered
pursuant to the distribution.

                  P = the offering price per share of the additional shares.

                  M = the Average Sale Price, minus, in the case of (i) a
distribution to which Section 10.06(c) applies or (ii) a distribution to which
Section 10.08 applies, for which, in each case, (x) the record date shall occur
on or before the record date for the distribution to which this Section 10.07
applies and (y) the Ex-Dividend Time shall occur on or after the date of the
Time of Determination for the distribution to which this Section 10.07 applies,
the fair market value (on the record date for the distribution to which this
Section 10.07 applies) of:

                  (1)      the Capital Stock of the Company distributed in
         respect of each share of Common Stock in such Section 10.06(c)
         distribution and

                                       72

<PAGE>

                  (2)      assets of the Company or debt securities or any
         rights, warrants or options to purchase securities of the Company
         distributed in respect of each share of Common Stock in such Section
         10.08 distribution.

                  The Board of Directors shall determine fair market values for
the purposes of this Section 10.07.

                  The adjustment shall become effective immediately after the
record date for the determination of shareholders entitled to receive the
rights, warrants or options to which this Section 10.07 applies. If any shares
of Common Stock subject to such rights, warrants or options have not been issued
when such rights, warrants or options expire (or to the extent such rights,
warrants or options are redeemed by the Company, or otherwise cease to be
convertible into, to be exchangeable for or to carry any such right to purchase
shares), then the Conversion Rate shall promptly be readjusted to the Conversion
Rate which would then be in effect had the adjustment upon the issuance of such
rights, warrants or options been made on the basis of the actual number of
shares of Common Stock issued upon the exercise of such rights, warrants or
options.

                  No adjustment shall be made under this Section 10.07 if the
application of the formula stated above in this Section 10.07 would result in a
value of R' that is equal to or less than the value of R.

                  SECTION 10.08 Adjustment for Other Distributions.

                  (a)      If, after the Issue Date of the Securities, the
Company distributes to all holders of its Common Stock any cash, assets
(excluding any Capital Stock of a Subsidiary or business unit) or evidence of
indebtedness but excluding any dividends and distributions referred to in
Section 10.06 and 10.07, the Conversion Rate shall be adjusted in accordance
with the formula:

                                    R x M
                               R' = -----
                                    M - F

                  where:

                  R' = the adjusted Conversion Rate.

                  R = the current Conversion Rate.

                  M = the Average Sale Price, minus, in the case of a
distribution to which Section 10.06(c) applies, for which (i) the record date
shall occur on or before the record date for the distribution to which this
Section 10.08 applies and (ii) the Ex-Dividend Time shall occur on or after the
date of the Time of Determination for the distribution to which this Section
10.08 applies, the fair market value (on the record date for the distribution to
which this Section 10.08 applies) of any Capital Stock of the Company

                                       73

<PAGE>

distributed in respect of each share of Common Stock in such Section 10.06(c)
distribution.

                  F = the fair market value (on the record date for the
distribution to which this Section 10.08 applies) of the assets, securities,
rights, warrants or options to be distributed in respect of each share of Common
Stock in the distribution to which this Section 10.08 is being applied
(including, in the case of cash dividends or other cash distributions giving
rise to an adjustment, all such cash distributed concurrently).

                  (b)      If, after the Issue Date of the Securities, the
Company pays a dividend or makes a distribution to all holders of its Common
Stock consisting of Capital Stock of any class or series, or similar equity
interests, of or relating to a Subsidiary or other business unit of the Company,
the Conversion Rate shall be adjusted in accordance with the formula:

                               R' = R x (1 + F/M)

                  where:

                  R' = the adjusted Conversion Rate.

                  R = the current Conversion Rate.

                  M = the average of the Sale Prices of the Common Stock for the
ten (10) trading days commencing on and including the fifth trading day after
the date on which "ex-dividend trading" commences for such dividend or
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 (the
"Ex-Dividend Date").

                  F = the fair market value of the securities distributed in
respect of each share of Common Stock for which this Section 10.08(b) applies
shall mean the number of securities distributed in respect of each share of
Common Stock multiplied by the average of the Sale Prices of those securities
distributed for the ten (10) trading days commencing on and including the fifth
trading day after the Ex-Dividend Date.

                  (c)      In the case of a tender or exchange offer (but not
including any purchases pursuant to a stock buy-back program) made by the
Company or any Subsidiary for all or any portion of the Common Stock (excluding
any transactions solely involving odd lots of shares of Common Stock) that has
expired and such tender or exchange offer (as amended upon the expiration
thereof) requires 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 Expiration Time exceeds the Sale Price
per share of Common Stock on the Trading Day next succeeding

                                       74

<PAGE>

the Expiration Time, the Conversion Rate shall be increased so that the
Conversion Rate shall equal the rate determined by multiplying the Conversion
Rate in effect immediately prior to the Expiration Time by a fraction:

                  (1)      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 Sale Price per share of Common
         Stock on the Trading Day next succeeding the Expiration Time, and

                  (2)      the denominator of which shall be the number of
         shares of Common Stock outstanding (including any tendered or exchanged
         shares (including Purchased Shares)) at the Expiration Time multiplied
         by the Sale Price per share of Common Stock on the Trading Day next
         succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business
on the day following the Expiration Time. "Expiration Time" with respect to a
tender offer or exchange offer, means the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer. Notwithstanding
the foregoing, if the Company is obligated to purchase shares pursuant to any
such tender or exchange offer, but the Company is permanently prevented by
applicable law from 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.

                  (d)      For purposes of this Section 10.08:

                  (1)      the Board of Directors shall determine fair market
         values for the purposes of this Section 10.08;

                  (2)      the adjustment shall become effective immediately
         after the record date for the determination of shareholders entitled to
         receive the distribution to which this Section 10.08 applies; and

                  (3)      in the event that, with respect to any distribution
         to which this Section 10.08 otherwise apply, the difference "M-F" as
         defined in the above formula is less than $1.00 or "F" is greater than
         "M", then the adjustment

                                       75

<PAGE>

         provided by this Section 10.08 shall not be made and in lieu thereof
         the provisions of the last paragraph of Section 10.14 shall apply to
         such distribution.

                  SECTION 10.09 When Adjustment May Be Deferred. No adjustment
in the Conversion Rate need be made unless the adjustment would require an
increase or decrease of at least 1% in the Conversion Rate. Any adjustments that
are not made shall be carried forward and taken into account in any subsequent
adjustment and all adjustments that are made and carried forward shall be taken
in the aggregate in order to determine if the 1% threshold is met.

                  All calculations under this Article 10 shall be made to the
nearest cent or to the nearest 1/1,000th of a share, as the case may be.

                  SECTION 10.10 When No Adjustment Required. For the avoidance
of doubt, the Conversion Rate shall only be subject to adjustment for the
circumstances and in the manner set forth in Sections 10.06, 10.07, 10.08 and
10.12 and for no other event or circumstance.

                  No adjustment need be made for a transaction referred to in
Section 10.06, 10.07, 10.08 or 10.14 if Securityholders are to participate in
the transaction on a basis and with notice that the Board of Directors
determines to be fair and appropriate in light of the basis and notice on which
holders of Common Stock participate in the transaction. Such participation by
Securityholders may include participation upon conversion provided that an
adjustment shall be made at such time as the Securityholders are no longer
entitled to participate.

                  No adjustment need be made for rights to purchase Common Stock
pursuant to a Company plan for reinvestment of dividends or interest.

                  No adjustment need be made for a change in the par value or no
par value of the Common Stock.

                  To the extent the Securities become convertible pursuant to
this Article 10 into cash, no adjustment need be made thereafter as to the cash.
Interest will not accrue on the cash.

                  No adjustment will be made pursuant to this Article 10 that
would result, through the application of two or more provisions hereof, in the
duplication of any adjustment.

                  SECTION 10.11 Notice of Adjustment. Whenever the Conversion
Rate is adjusted, the Company shall promptly mail to Securityholders a notice of
the adjustment. The Company shall file with the Trustee and the Conversion Agent
such notice and a certificate from the Company's independent public accountants
briefly

                                       76

<PAGE>

stating the facts requiring the adjustment and the manner of computing it. Upon
receipt by it of such notice, and at the written request of the Company, the
Conversion Agent will promptly mail such notice to Securityholders at the
Company's expense. The certificate shall be conclusive evidence that the
adjustment is correct. Neither the Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such certificate except to
exhibit the same to any Holder desiring inspection thereof.

                  SECTION 10.12 Voluntary Increase. The Company from time to
time may increase the Conversion Rate by any amount for any period of time.
Whenever the Conversion Rate is increased, the Company shall file with the
Trustee and the Conversion Agent a notice of the increase, and the Conversion
Agent will mail such notice to the Securityholders, at the Company's expense.
The Company shall mail the notice at least 15 days before the date the increased
Conversion Rate takes effect. The notice shall state the increased Conversion
Rate and the period it will be in effect.

                  A voluntary increase of the Conversion Rate does not change or
adjust the Conversion Rate otherwise in effect for purposes of Section 10.06,
10.07 or 10.08.

                  SECTION 10.13 Notice of Certain Transactions. If:

                  (a)      the Company takes any action that would require an
         adjustment in the Conversion Rate pursuant to Section 10.06, 10.07 or
         10.08 (unless no adjustment is to occur pursuant to Section 10.09 or
         10.10); or

                  (b)      the Company takes any action that would require a
         supplemental indenture pursuant to Section 10.14; or

                  (c)      there is a liquidation or dissolution of the Company;

then the Company shall mail to Securityholders and file with the Trustee and the
Conversion Agent a notice stating the proposed record date for a dividend or
distribution or the proposed effective date of a subdivision, combination,
reclassification, consolidation, merger, binding share exchange, transfer,
liquidation or dissolution. The Company shall file and mail the notice at least
15 days before such date. Failure to file or mail the notice or any defect in it
shall not affect the validity of the transaction.

                  SECTION 10.14 Reorganization of Company; Special
Distributions. If the Company is a party to a transaction subject to Section
5.01 (other than a sale of all or substantially all of the assets of the Company
in a transaction in which the holders of Common Stock immediately prior to such
transaction do not receive securities, cash, property or other assets of the
Company or any other Person) or a merger or binding share exchange which
reclassifies or changes its outstanding Common Stock, the Person, if other than
the Company, obligated to deliver securities, cash or other assets upon
conversion of Securities shall enter into a supplemental indenture. If the
issuer of

                                       77

<PAGE>

securities deliverable upon conversion of Securities is an Affiliate of the
successor company, that issuer shall join in the supplemental indenture.

                  The supplemental indenture shall provide that the Holder's
right to convert its Security into Common Stock shall be changed into a right to
convert such Security into the kind and amount of securities, cash or other
assets which such Holder would have received immediately after the
consolidation, merger, binding share exchange or transfer if such Holder had
converted the Security immediately before the effective date of the transaction,
assuming (to the extent applicable) that such Holder (i) was not a constituent
Person or an Affiliate of a constituent Person to such transaction; (ii) made no
election with respect thereto; and (iii) was treated alike with the plurality of
non-electing Holders. The supplemental indenture shall provide for adjustments
which shall be as nearly equivalent as may be practical to the adjustments
provided for in this Article 10. The successor company shall mail to
Securityholders a notice briefly describing the supplemental indenture.

                  If this Section applies, neither Section 10.06 nor 10.07
applies.

                  If the Company makes a distribution to all holders of its
Common Stock of any of its assets, or debt securities or any rights, warrants or
options to purchase securities of the Company that but for the provisions of the
last paragraph of 10.08 would otherwise result in an adjustment in the
Conversion Rate pursuant to the provisions of Section 10.08, then, from and
after the record date for determining the holders of Common Stock entitled to
receive the distribution, a Holder of a Security that converts such Security in
accordance with the provisions of this Indenture shall upon such conversion be
entitled to receive, in addition to the shares of Common Stock into which the
Security is convertible, the kind and amount of securities, cash or other assets
comprising the distribution that such Holder would have received if such Holder
had converted the Security immediately prior to the record date for determining
the holders of Common Stock entitled to receive the distribution.

                  SECTION 10.15 Company Determination Final. Any determination
that the Company or the Board of Directors must make pursuant to Section 10.03,
10.06, 10.07, 10.08, 10.09, 10.10 or 10.14 is conclusive.

                  SECTION 10.16 Trustee's Adjustment Disclaimer. Except as
provided in last paragraph of Section 10.01, the Trustee has no duty to
determine when an adjustment under this Article 10 should be made, how it should
be made or what it should be. The Trustee has no duty to determine whether a
supplemental indenture under Section 10.14 need be entered into or whether any
provisions of any supplemental indenture are correct. The Trustee shall not be
accountable for and makes no representation as to the validity or value of any
securities or assets issued upon conversion of Securities. The Trustee shall not
be responsible for the Company's failure

                                       78

<PAGE>

to comply with this Article 10. Each Conversion Agent (other than the Company or
an Affiliate of the Company) shall have the same protection under this Section
10.16 as the Trustee.

                  SECTION 10.17 Simultaneous Adjustments. In the event that this
Article 10 requires adjustments to the Conversion Rate under more than one of
Sections 10.06, 10.07 or 10.08, and the record dates for the distributions
giving rise to such adjustments shall occur on the same date, then such
adjustments shall be made by applying, first, the provisions of Section 10.06,
second, the provisions of Section 10.08 and, third, the provisions of Section
10.07.

                  SECTION 10.18 Successive Adjustments. After an adjustment to
the Conversion Rate under this Article 10, any subsequent event requiring an
adjustment under this Article 10 shall cause an adjustment to the Conversion
Rate as so adjusted.

                  SECTION 10.19 Rights Issued in Respect of Common Stock Issued
upon Conversion. Each share of Common Stock issued upon conversion of Securities
pursuant to this Article 10 shall be entitled to receive the appropriate number
of common stock or preferred stock purchase rights, as the case may be (the
"Rights"), if any, that all shares of Common Stock are entitled to receive and
the certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
shareholder rights agreement adopted by the Company, as the same may be amended
from time to time (in each case, a "Rights Agreement"), whether or not such
rights have separated from the Common Stock at the time of such conversion.
Provided that such Rights Agreement requires that each share of Common Stock
issued by the Company (including those that might be issued upon conversion of
Securities) at any time prior to the distribution of separate certificates
representing the Rights be entitled to receive such Rights, then,
notwithstanding anything else to the contrary in the Securities or this Article
10, there shall not be any adjustment to the conversion privilege or Conversion
Rate or any other term or provision of the Securities as a result of the
issuance of Rights, the distribution of separate certificates representing the
Rights, the exercise or redemption of such Rights in accordance with any such
Rights Agreement, or the termination or invalidation of such Rights.
Notwithstanding anything to the contrary herein, nothing in this provision is
intended to confer on the Common Stock issuable upon conversion of Securities
any right that is different than the rights to which all shares of Common Stock
of the Company are entitled to receive.

                  SECTION 10.20 Company's Right to Elect to Pay Cash or Common
Stock. In lieu of delivery of Common Stock upon notice of conversion of any
Securities (for all or any portion of the Securities), the Company may elect to
pay Holders surrendering Securities an amount in cash for each $1,000 principal
amount equal to the average of the Sale Price of Common Stock for the five
consecutive trading days

                                       79

<PAGE>

immediately following either (a) the date of notice of election to deliver cash
as described below if the Company has not given notice of redemption pursuant to
Section 3.03, or (b) the conversion date if the Company has given notice of
redemption specifying that the Company intends to deliver cash upon conversion,
in either case such average Sales Price multiplied by the Conversion Rate in
effect on that date. The Company will inform the Holders through the Trustee no
later than two Business Days following the date it receives a conversion notice
as set forth in paragraph 8(f) of the Securities, of the Company's election to
deliver shares of Common Stock or to pay cash in lieu of delivery of Common
Stock, unless the Company has already informed Holders of its election in
connection with its optional redemption of the Securities pursuant to Section
3.01 herein. If the Company elects to deliver all of such payment in Common
Stock, the Common Stock will be delivered by the Company through the Conversion
Agent no later than the fifth Business Day following the Conversion Date. If the
Company elects to pay all or a portion of such payment in cash, the payment,
including any delivery of Common Stock, will be made to Holders surrendering
Securities no later than the tenth Business Day following the applicable
conversion date. If an Event of Default (other than a default in a cash payment
upon conversion of the Securities) has occurred and is continuing, the Company
may not pay cash upon conversion of any Security or portion of a Security (other
than cash for fractional shares).

                                   ARTICLE 11

                               PAYMENT OF INTEREST

                  SECTION 11.01 Interest Payments. Interest on any Security that
is payable, and is punctually paid or duly provided for, on any applicable
payment date shall be paid to the person in whose name that Security is
registered at the close of business each March 8 and September 8 (each a
"Regular Record Date") at the office or agency of the Company maintained for
such purpose. Each installment of interest on any Security shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States, if the Trustee shall have received proper wire transfer
instructions from such payee not later than the related Regular Record Date. If
no such instructions have been received or if the payee is a Holder of less than
1,000,000 aggregate principal amount of the Securities, the Company may elect to
pay the installment of interest by check drawn on a bank in New York City mailed
to the payee at its address set forth on the Registrar's books. In the case of a
permanent Global Security, interest payable on any applicable payment date will
be paid to the Depositary, with respect to that portion of such permanent Global
Security held for its account by Cede & Co. for the purpose of permitting such
party to credit the interest received by it in respect of such permanent Global
Security to the accounts of the beneficial owners thereof.

                  SECTION 11.02 Defaulted Interest. Except as otherwise
specified with respect to the Securities, any interest on any Security that is
payable, but is not punctually

                                       80

<PAGE>

paid or duly provided for, within 30 days following any applicable payment date
(herein called "Defaulted Interest", which term shall include any accrued and
unpaid interest that has accrued on such defaulted amount in accordance with
paragraph 1 of the Securities), shall forthwith cease to be payable to the
registered Holder thereof on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the Company,
at its election in each case, as provided in clause (1) or (2) below:

                  (1)      The Company may elect to make payment of any
         Defaulted Interest to the persons in whose names the Securities are
         registered at the close of business on a special record date for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Security
         and the date of the proposed payment (which shall not be less than 20
         days after such notice is received by the Trustee), and at the same
         time the Company shall deposit with the Trustee an amount of money
         equal to the aggregate amount proposed to be paid in respect of such
         Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit 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 (the
         "Special Record Date") for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be mailed, first-class postage prepaid, to each
         Holder of Securities at his address as it appears on the list of
         Securityholders maintained pursuant to Section 2.05 not less than 10
         days prior to such Special Record Date. Notice of the proposed payment
         of such Defaulted Interest and the Special Record Date therefor having
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         persons in whose names the Securities are registered at the close of
         business on such Special Record Date and shall no longer be payable
         pursuant to the following clause (2).

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

<PAGE>

                  SECTION 11.03 Interest Rights Preserved. Subject to the
foregoing provisions of this Article 11 and Section 2.06, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue interest, which were carried by such other Security.

                                   ARTICLE 12

                                    GUARANTEE

                  SECTION 12.01 Guarantee. The Guarantor hereby unconditionally
guarantees, on an unsecured basis, to each Holder of a Security authenticated
and delivered by the Trustee in accordance with the terms hereof, and to the
Trustee on behalf of such Holder, (i) (x) the due and punctual payment of the
principal of, and interest on, such Security, when and as the same shall become
due and payable, whether at Stated Maturity, by acceleration, redemption or
otherwise, (y) the due and punctual payment of interest on the overdue principal
and interest, if any, on such Security, to the extent lawful, and (z) the
faithful performance of all other obligations of the Company to the Holders or
the Trustee under such Security and this Indenture and (ii) in case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, that the same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise.

                  The Guarantor hereby agrees that its obligations hereunder
shall be unconditional, irrespective of (to the extent permitted by law) the
validity, regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
with respect to any provisions hereof or thereof, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of the Guarantor.

                  The Guarantor hereby waives (to the extent permitted by law)
the benefits of diligence, presentment, demand for payment, filing of claims
with a court in the event of insolvency or bankruptcy of the Company, any right
to require a proceeding first against the Company or any other Person, protest,
notice and all demands whatsoever and covenants that the Guarantee shall not be
discharged as to any Security except by complete performance of the obligations
contained in such Security, and this Indenture and the Guarantee (to the extent
that any obligations under this Indenture and the Guarantee relate to and are
outstanding with respect to such Security). The Guarantor acknowledges that the
Guarantee is a guarantee of payment and not of collection.

                  The Guarantor hereby agrees that, in the event of a default in
payment of principal or interest on such Security, whether at its Stated
Maturity, by acceleration,

                                       82

<PAGE>

redemption, purchase or otherwise, legal proceedings may be instituted by the
Trustee on behalf of, or by, the Holder of such Security, subject to the terms
and conditions set forth in this Indenture, directly against the Guarantor to
enforce the Guarantee without first proceeding against the Company. The
Guarantor agrees that if, after the occurrence and during the continuance of an
Event of Default, the Trustee or any of the Holders are prevented by applicable
law from exercising their respective rights to accelerate the maturity of the
Securities, to collect interest on the Securities, or to enforce or exercise any
other right or remedy with respect to the Securities, the Guarantor shall pay to
the Trustee for the account of the Holder, upon demand therefor, the amount that
would otherwise have been due and payable had such rights and remedies been
permitted to be exercised by the Trustee or any of the Holders.

                  The Guarantor hereby agrees to pay any and all costs and
expenses incurred by the Trustee or the Holders in enforcing their respective
rights under the Guarantee.

                  The Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the Company
for liquidation, reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets.

                  SECTION 12.02 Severability. In case any provision of the
Guarantee shall be invalid, illegal or unenforceable, the validity, legality,
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

                  SECTION 12.03 Limitation of Guarantor's Liability. Any term or
provision of this Indenture notwithstanding, the Guarantee shall not exceed the
maximum amount that can be guaranteed by the Guarantor without rendering the
Guarantee voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

                  SECTION 12.04 Subrogation. The Guarantor shall be subrogated
to all rights of Holders against the Company in respect of any amounts paid by
the Guarantor pursuant to the provisions of Section 12.01; provided, however,
that, if an Event of Default has occurred and is continuing, the Guarantor shall
not be entitled to enforce or receive any payments arising out of, or based
upon, such right of subrogation until all amounts then due and payable by the
Company under this Indenture or the Securities shall have been paid in full.

                  SECTION 12.05 Reinstatement. The Guarantor hereby agrees that
the Guarantee provided for in Section 12.01 shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof,
made by or on behalf of the

                                       83

<PAGE>

Company or the Guarantor in respect of any of the obligations under the
Securities or the Indenture is rescinded or must otherwise be restored or
returned by any Holder or the Trustee for any reason whatsoever, whether upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Company, or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for the Company or any substantial
part of its properties, or otherwise, all as though such payment had not been
made.

                  SECTION 12.06 Benefits Acknowledged. The Guarantor
acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by this Indenture and that its guarantee and
waivers pursuant to its Guarantee are knowingly made in contemplation of such
benefits.

                  SECTION 12.07 Authentication Required. The Guarantee shall not
be valid or obligatory for any purpose until the certificate of authentication
on the Securities shall have been executed by the Trustee under the Indenture by
the manual signature of one of its authorized signatories.

                  SECTION 12.08 Release of the Guarantor. Concurrently with the
discharge of the Securities under Section 8.01, the Guarantor shall be released
from its obligations under the Guarantee.

                                   ARTICLE 13

                                  MISCELLANEOUS

                  SECTION 13.01 Trust Indenture Act Controls. This Indenture is
subject to the TIA and if any provision hereof limits, qualifies or conflicts
with a provision of the TIA that is required by the TIA to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the TIA that may be so
modified or excluded, the latter provision shall be deemed to apply to this
Indenture as so modified, or to be excluded, as the case may be, whether or not
such provision of this Indenture refers expressly to such provision of the TIA.

                  SECTION 13.02 Notices.

                  (a)      Unless provided otherwise in this Indenture, any
request, demand, authorization, direction, notice, consent, waiver or Act of
Securityholders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

                  (1)      the Trustee by any Securityholder or by the Company

         to or with the Trustee at its Corporate Trust Office, Attention:
         Roseline Maney, or

                  (2)      the Company by the Trustee or by any Securityholder
         shall be sufficient for every purpose hereunder if in writing and
         mailed, first-class postage prepaid, to the Company addressed to it at
         AMR Corporation, P.O. Box 619616, Dallas/Fort Worth Airport, Texas
         75261-9616, Attention: Treasurer, or at any other address previously
         furnished in writing to the Trustee by the Company.

                  (b)      Any notice or communication given to a Securityholder
shall be mailed to the Securityholder, by first-class mail, postage prepaid, at
the Securityholder's address as it appears on the registration books of the
Registrar and shall be sufficiently given (unless otherwise herein expressly
provided) if so mailed within the time prescribed.

                  Failure to mail a notice or communication to a Securityholder
or any defect in it shall not affect its sufficiency with respect to other
Securityholders. If a notice or communication is mailed in the manner provided
above, it is duly given, whether or not received by the addressee.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee (such approval not to be unreasonably withheld) shall constitute a
sufficient notification for every purpose hereunder. If it is impossible or, in
the opinion of Trustee, impracticable to give any notice by publication in the
manner herein required, then such publication in lieu thereof as shall be made
with the approval of the Trustee will constitute a sufficient publication of
such notice.

                  Any request, demand, authorization, direction, notice, consent
or waiver required or permitted under this Indenture shall be in the English
language.

                  Where this indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be equivalent of such
notice. Waiver of notice by Securityholders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

                  (c)      If the Company mails a notice or communication to the
Securityholders, it shall mail a copy to the Trustee and each Registrar, Paying
Agent, Conversion Agent or co-registrar. The Trustee shall promptly furnish the
Company with a copy of any report, demand, notice or written communication
received by the Trustee hereunder from, or sent or furnished by the Trustee
hereunder to, any Securityholder.

         of the signers, all conditions precedent, if any, provided for in this
         Indenture relating to the proposed action have been complied with; and

                  (b)      an Opinion of Counsel stating that, in the opinion of
         such counsel, all such conditions precedent, if any, have been complied
         with;

provided that, in the case of any such request or application as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular request or application, no additional
certificate or opinion need be furnished.

                  SECTION 13.05 Statements Required in Certificate or Opinion.

                  (b)      In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not
necessary that all such matters be certified by, or covered by the opinion of,
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents.

                  Any certificate or opinion of an Officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such Officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or any Opinion of Counsel may be based, insofar
as it relates to factual matters, upon a certificate or opinion of, or
representations by, an Officer or Officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations as to such matters are
erroneous.

                  Any certificate or opinion of an Officer of the Company or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows, or in the exercise of reasonable care should know, that the
certificate or opinions or representations as to such accounting matters are
erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  SECTION 13.06 Separability Clause. In case any provision in
this Indenture or in the Securities shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

                  SECTION 13.07 Rules by Trustee, Paying Agent, Conversion Agent
and Registrar. The Company and the Trustee may make reasonable rules for action
by or a meeting of Securityholders. The Registrar, Conversion Agent and the
Paying Agent may make reasonable rules for their functions.

be the obligation

                                       87

binding on the Company and the Holders absent manifest error. The Trustee,
Paying Agent and Conversion Agent shall not be obligated to recalculate,
recompute or confirm any such calculations.

                  SECTION 13.09 Legal Holidays. A "Legal Holiday" is any day
other than a Business Day. If any specified date (including a date for giving
notice) is a Legal Holiday, the action shall be taken on the next succeeding day
that is not a Legal Holiday with the same force and effect as if made on such
specified date, and, if the action to be taken on such date is a payment in
respect of the Securities, no interest, if any, shall accrue for the intervening
period.

                  SECTION 13.10 Governing Law. THIS INDENTURE, THE SECURITIES
AND THE GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND
PERFORMANCE APPLICABLE TO AGREEMENTS MADE OR INSTRUMENTS ENTERED INTO, AND, IN
EACH CASE, PERFORMED IN SUCH STATE.

                  SECTION 13.11 No Recourse Against Others. No past, present or
future director, officer, employee, agent, representative, member, manager,
trustee, stockholder or other equity holder, as such, of the Company, the
Guarantor or any successor Person or any Affiliate of any thereof shall have any

Person or any Affiliate of any thereof, either directly or through the Company,
the Guarantor or any successor Person or any Affiliate of any thereof, under the
Securities, this Indenture or the Guarantee or for any claim based on, in
respect of or by reason of such obligations or their creation, whether by virtue
of any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise. By
accepting a Security, each Securityholder shall waive and release all such
liability. The waiver and release shall be part of the consideration for the
issue of the Securities.

                  SECTION 13.12 Successors. All agreements of the Company and
the Guarantor in this Indenture and the Securities shall bind its respective
successor. All agreements of the Trustee in this Indenture shall bind its
successor.

provision of this Indenture and that is authorized or required to be done or
performed by any board, committee or Officer of the Company or the Guarantor
shall and may be done and performed with like force and effect by the like
board, committee or officer of any corporation that shall at the time be the
successor or assign of the Company or the Guarantor.

                     4.25% Senior Convertible Note due 2023

1.       Interest.

                  The Company promises to pay interest on the principal amount
of this Security at the rate per annum of 4.25% from the Issue Date, or from the
most recent date to which interest has been paid or provided for. During such
period, the Company will pay interest semiannually in arrears on March 23 and
September 23 of each year, commencing on March 23, 2004 (each an "Interest
Payment Date"), to Holders of record at the close of business on each March 8
and September 8 (whether or not a business day) (each a "Regular Record Date")
immediately preceding such Interest Payment Date. Interest on the Securities
will accrue from the most recent date to which interest has been paid or duly
provided or, if no interest has been paid, from the Issue Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

                  If the principal amount hereof or any portion of such
principal amount is not paid when due (whether upon acceleration pursuant to
Section 6.02 of the Indenture, upon the date set for payment of the Redemption
Price pursuant to paragraph 5 hereof, upon the date set for payment of the
Purchase Price or Change in Control Purchase Price pursuant to paragraph 6
hereof or upon the Stated Maturity of this Security) or if interest due hereon
or any portion of such interest is not paid when due in accordance with
paragraph 5 or 10 hereof, then in each such case the overdue amount shall, to
the extent permitted by law, bear interest at the rate of 4.25% per annum,
compounded semiannually, which interest shall accrue from the date such overdue
amount was originally due to the date payment of such amount, including interest
thereon, has been made or duly provided for. All such interest shall be payable
on demand.

2.       Method of Payment.

                  Subject to the terms and conditions of the Indenture, the
Company will make payments in respect of Redemption Price, Purchase Price and
Change in Control Purchase Price and at Stated Maturity to Holders who surrender
Securities to a Paying Agent to collect such payments in respect of the
Securities. The Company will pay any cash amounts in money of the United States
that at the time of payment is legal tender for payment of public and private
debts. However, the Company may make such cash payments by check payable in such
money or by wire transfer.

3.       Paying Agent, Conversion Agent and Registrar.

                  Initially, Wilmington Trust Company, a Delaware banking
corporation (the "Trustee"), will act as Paying Agent, Conversion Agent and
Registrar. The Company may appoint and change any Paying Agent, Conversion
Agent, Registrar or co-registrar without notice, other than notice to the
Trustee except that the Company will

                                     A-1-5

<PAGE>

maintain at least one Paying Agent in the State of New York, City of New York,
Borough of Manhattan, which shall initially be an office or agency of the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may
act as Paying Agent, Conversion Agent, Registrar or co-registrar.

4.       Indenture.

                  The Company issued and the Guarantor has guaranteed the
Securities pursuant to an Indenture, dated as of September 23, 2003 (the
"Indenture"), among the Company, the Guarantor and the Trustee. Capitalized
terms used herein and not defined herein have the meanings ascribed thereto in
the Indenture. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the TIA. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the TIA for a statement of those terms.

                  The Securities and the Guarantee are general unsecured and
unsubordinated obligations of the Company and the Guarantor, respectively,
limited to $300,000,000 aggregate principal amount (subject to Sections 2.02 and
2.07 of the Indenture). The Indenture does not limit other indebtedness of the
Company or the Guarantor secured or unsecured.

5.       Redemption at the Option of the Company.

                  No sinking fund is provided for the Securities. The Securities
are redeemable as a whole, or from time to time in part, at any time at the
option of the Company in accordance with the Indenture at a price equal to the
principal amount of the Securities (the "Redemption Price") together with
accrued and unpaid interest, if any, provided that the Securities are not
redeemable prior to September 23, 2008.

6.       Purchase by the Company at the Option of the Holder.

                  Subject to the terms and conditions of the Indenture, the
Company shall become obligated to purchase, at the option of the Holder, the
Securities held by such Holder on each of September 23, 2008, 2013 and 2018
(each a "Purchase Date") at a price equal to the principal amount of the
Securities plus accrued and unpaid interest, if any (the "Purchase Price"), upon
delivery of a Purchase Notice containing the information set forth in the
Indenture, at any time from the opening of business on the date that is 20
Business Days prior to such Purchase Date until the close of business on the
second Business Day immediately preceding such Purchase Date and upon delivery
of the Securities to the Paying Agent by the Holder as set forth in the
Indenture.

                  The Purchase Price may be paid, at the option of the Company,
in cash or by the issuance and delivery of shares of Common Stock of the
Company, or in any combination thereof in accordance with the Indenture. If the
Company elects to pay any

                                     A-1-6

<PAGE>

portion of the Purchase Price in its Common Stock, the Company shall issue a
number of shares of its Common Stock equal to such portion of the Purchase Price
to be paid in Common Stock divided by the Market Price of a share of Common
Stock.

                  At the option of the Holder and subject to the terms and
conditions of the Indenture, the Company shall become obligated to purchase the
Securities held by such Holder on a date selected by the Company no later than
30 Business Days after the occurrence of a Change in Control for a Change in
Control Purchase Price equal to the principal amount of the Securities plus
accrued and unpaid interest, if any, to but not including the Change in Control
Purchase Date.

                  The Change in Control Purchase Price may be paid (at the
option of the Company) in cash or by the issuance and delivery of shares of
Common Stock of the Company, or in any combination thereof in accordance with
the Indenture. If the Company elects to pay any portion of the Change in Control
Purchase Price in its Common Stock, the Company shall issue a number of shares
of its Common Stock equal to such portion of the Change in Control Purchase
Price to be paid in Common Stock divided by 97 1/2% of the Market Price of a
share of Common Stock.

                  A third party may make the offer and purchase of the
Securities in lieu of the Company in accordance with the Indenture.

                  Holders have the right to withdraw any Purchase Notice or
Change in Control Purchase Notice, as the case may be, by delivering to the
Paying Agent a written notice of withdrawal in accordance with the provisions of
the Indenture.

                  If cash (and/or Common Stock if permitted under the Indenture)
sufficient to pay the Purchase Price or Change in Control Purchase Price, as the
case may be, of all Securities or portions thereof to be purchased as of the
Purchase Date or the Change in Control Purchase Date, as the case may be, is
deposited with the Paying Agent on the Business Day following the Purchase Date
or the Change in Control Purchase Date, as the case may be, interest shall cease
to accrue on such Securities (or portions thereof) at the close of business on
such Purchase Date or Change in Control Purchase Date, as the case may be, and
the Holder thereof shall have no other rights as such (other than the right to
receive the Purchase Price or Change in Control Purchase Price, as the case may
be, if any, upon surrender of such Security).

7.       Notice of Redemption.

                  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder of Securities to be
redeemed at the Holder's registered address. If money sufficient to pay the
Redemption Price of, and accrued and unpaid interest, if any, with respect to
all Securities (or portions thereof) to

                                     A-1-7

<PAGE>

be redeemed on the Redemption Date is deposited with the Paying Agent prior to
or on the Redemption Date, on such Redemption Date, interest shall cease to
accrue on such Securities or portions thereof. Securities in principal
denominations larger than $1,000 of principal amount may be redeemed in part but
only in integral multiples of $1,000 of principal.

8.       Conversion.

         (a)      Conversion Based on Common Stock Price. Subject to the
provisions of this paragraph 8 and the Indenture but notwithstanding the fact
that any other condition to conversion in paragraph 8(b), (c), (d) or (e) has
not been satisfied, Holders may surrender the Securities for conversion into
Common Stock on a Conversion Date in any calendar quarter commencing after
September 30, 2003, if the Sale Price of the Common Stock for at least 20
trading days in a period of 30 consecutive trading days ending on the last
trading day of the preceding calendar quarter is greater than 120% of the
Conversion Price per share of Common Stock on the last trading day of such
preceding calendar quarter. If the foregoing condition is satisfied, then the
Securities will be convertible at any time thereafter by the Holder, through the
maturity of the Securities.

         (b)      Conversion Based on Trading Price of the Securities. Subject
to the provisions of this paragraph 8 and the Indenture but notwithstanding the
fact that any other condition to conversion in paragraph 8(a), (c), (d) or (e)
has not been satisfied, the Securities may be surrendered for conversion prior
to maturity at any time during the five Business Day period after any five
consecutive trading day period in which the trading price per $1,000 principal
amount of the Securities for that five trading-day period was less than 98% of
the product of the Sale Price for the Common Stock and the Conversion Rate.

                  If on the date of any conversion pursuant to this paragraph
8(b), the Sale Price of our Common Stock is greater than the Conversion Price,
then Securityholders will receive, in lieu of Common Stock based on the
Conversion Price, cash or Common Stock or a combination of cash and Common
Stock, at the Company's option, with a value equal to the principal amount of
such Securities, plus the accrued and unpaid interest, if any, as of the
Conversion Date ("Principal Value Conversion"). The Company will notify
Securityholders that surrender their Securities for conversion, if it is a
Principal Value Conversion, by the second trading day following the date of
conversion, whether the Company will pay them all or a portion of the principal
amount of such Securities, plus accrued and unpaid interest, if any, in cash,
Common Stock or a combination of cash and Common Stock, and in what percentage.
Any Common Stock delivered upon a Principal Value Conversion will be valued at
the greater of the Conversion Price on the Conversion Date and the applicable
stock price as of the Conversion Date. The Company will pay such Securityholders
any portion of the principal amount of such Securities, plus accrued and unpaid
interest, if any, to be paid in

                                     A-1-8

<PAGE>

cash and deliver Common Stock with respect to any portion of the principal
amount of such Securities, plus accrued and unpaid interest, if any, to be paid
in Common Stock no later than the third Business Day following the determination
of the applicable stock price.

                  The "applicable stock price" means, in respect of a date of
determination, the average of the Sale Price per share of Common Stock over the
five-trading day period starting the third trading day following such date of
determination.

                  The "trading price" of the Securities on any date of
determination means the average of the secondary market bid quotations obtained
by the Trustee for $5 million principal amount of the Securities at
approximately 3:30 p.m., New York City time, on such determination date from
three independent nationally recognized securities dealers the Company selects;
provided that if three such bids cannot reasonably be obtained by the Trustee,
but two such bids are obtained, then the average of the two bids shall be used,
and if only one such bid can reasonably be obtained by the Trustee, that one bid
shall be used. If the Trustee cannot reasonably obtain at least one bid for $5
million principal amount of the Securities from a nationally recognized
securities dealer, then the trading price per $1,000 principal amount of
Securities will be deemed to be less than 98% of the product of the Sale Price
of the Common Stock and the Conversion Rate.

                  In connection with any conversion upon satisfaction of the
above trading pricing condition, the Trustee shall have no obligation to
determine the trading price of the Securities unless the Company has requested
such determination; and the Company shall have no obligation to make such
request unless a Holder of the Securities provides the Company with reasonable
evidence that the trading price per $1,000 principal amount of Securities would
be less than 98% of the product of the Sale Price of our Common Stock and the
Conversion Rate. At such time, the Company shall instruct the Trustee to
determine the trading price of the Securities beginning on the next trading day
and on each successive trading day until the trading price per $1,000 principal
amount of the Securities is greater than 98% of the product of the Sale Price of
the Company's Common Stock and the Conversion Rate.

         (c)      Conversion upon Redemption. Subject to the provisions of this
paragraph 8 and the Indenture but notwithstanding the fact that any other
condition to conversion in paragraph 8(a), (b), (d) or (e) has not been
satisfied, a Holder may surrender for conversion into Common Stock a Security or
portion of a Security which has been called for redemption pursuant to paragraph
5 hereof, but such Securities may be surrendered for conversion until the close
of business on the second Business Day immediately preceding the Redemption
Date.

         (d)      Conversion upon Certain Distributions. Subject to the
provisions of this paragraph 8 and the Indenture but notwithstanding the fact
that any other condition to

                                     A-1-9

<PAGE>

conversion in paragraph (a), (b), (c) or (e) has not been satisfied, in the
event that the Company declares a dividend or distribution described in Section
10.07 of the Indenture, or a dividend or a distribution described in Section
10.08(a) or 10.08(b) of the Indenture where in the case of a dividend or
distribution pursuant to 10.08(a) or 10.08(b), the fair market value, per share,
of such dividend or distribution per share of Common Stock, as determined in the
Indenture, exceeds 15% of the Sale Price of the Common Stock on the Business Day
immediately preceding the date of declaration for such dividend or distribution,
then the Securities may be surrendered for conversion beginning on the date the
Company gives notice to the Holders of such right, which shall not be less than
20 days prior to the date for such dividend or distribution, and Securities may
be surrendered for conversion at any time thereafter until the close of business
on the Business Day prior to the date of distribution or until the Company
announces that such dividend or distribution will not take place.

         (e)      Conversion upon the Occurrence of Certain Corporate
Transactions. Subject to the provisions of this paragraph 8 and the Indenture
but notwithstanding the fact that any other condition to conversion in paragraph
(a), (b), (c) or (d) has not been satisfied, in the event the Company is a party
to a transaction described in the first paragraph of Section 10.14 of the
Indenture, the Securities may be surrendered for conversion at any time from and
after the date which is 15 days prior to the date the Company announces the
anticipated effective date until 15 days after the actual effective date of such
transaction, and at the effective time of such transaction, the right to convert
a Security into Common Stock will be deemed to have changed into a right to
convert it into the kind and amount of cash, securities or other assets of the
Company or other Person which the holder would have received if the holder had
converted its Security immediately prior to the applicable record date for the
transaction.

         (f)      General Provisions. A Security in respect of which a Holder
has delivered a Purchase Notice or Change in Control Purchase Notice exercising
the option of such Holder to require the Company to purchase such Security may
be converted only if such notice of exercise is withdrawn in accordance with the
terms of the Indenture.

                  The initial Conversion Rate is 57.61 shares of Common Stock
per $1,000 principal amount, subject to adjustment in certain events described
in the Indenture. The Company will pay cash in lieu of any fractional share of
Common Stock.

                  The Company may elect to pay cash in lieu of delivering Common
Stock upon notice of conversion in accordance with Section 10.20 of the
Indenture.

                  To convert a Security, a Holder must (1) complete and manually
sign the conversion notice below (or complete and manually sign a facsimile of
such notice) and deliver such notice to the Conversion Agent, (2) surrender the
Security to the Conversion Agent, (3) furnish appropriate endorsements and
transfer documents if required by the

                                     A-1-10

<PAGE>

Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar
tax, if required.

                  A Holder may convert a portion of a Security if the principal
amount of such portion is $1,000 or an integral multiple of $1,000. No payment
or adjustment will be made for dividends on the Common Stock except as provided
in the Indenture. On conversion of a Security, the accrued and unpaid interest,
if any, with respect to the converted Security shall not be cancelled,
extinguished or forfeited, but rather shall be deemed to be paid in full to the
Holder thereof through the delivery of the Common Stock or cash, or combination
thereof (together with the cash payment, if any, in lieu of fractional shares),
in exchange for the Security being converted pursuant to the terms hereof; and
the fair market value of such shares of Common Stock or cash, or combination
thereof (together with any such cash payment in lieu of fractional shares),
shall be treated as issued, to the extent thereof, first in exchange for the
accrued and unpaid interest, if any, through the Conversion Date and the
balance, if any, of such fair market value of such Common Stock or cash, or
combination thereof (and any such cash payment), shall be treated as issued in
exchange for the principal amount of the Security being converted pursuant to
the provisions hereof.

                  In accordance with Sections 10.06, 10.07 and 10.08 of the
Indenture, the Conversion Rate will be adjusted, as further provided in the
Indenture, for dividends or distributions on Common Stock payable in Common
Stock or other Capital Stock; subdivisions, combinations or certain
reclassifications of Common Stock; distributions to all holders of Common Stock
of certain rights to purchase Common Stock for a period expiring within 60 days
of the record date for such distribution at a price per share of Common Stock
less than the Sale Price of the Common Stock at the Time of Determination;
distributions to all holders of Common Stock of cash, assets or evidence of
indebtedness of the Company (including shares of Capital Stock of a Subsidiary);
and for the purchase of Common Stock pursuant to a tender offer or exchange
offer for Common Stock (excluding odd lots of Common Stock) made by the Company
or any Subsidiary. However, no adjustment need be made if Securityholders may
participate in the transaction or in certain other cases specified in the
Indenture. The Company from time to time may voluntarily increase the Conversion
Rate.

                  If the Company is a party to a consolidation, merger or
binding share exchange or a transfer of all or substantially all of its assets,
or upon certain distributions described in the Indenture, the right to convert a
Security into Common Stock may be changed into a right to convert it into
securities, cash or other assets of the Company or another person in the
circumstances described in the Indenture.

9.       Conversion Arrangement on Call for Redemption.

                  Any Securities called for redemption, unless surrendered for
conversion before the close of business on the Redemption Date, may be deemed to
be purchased from the Holders of such Securities at an amount not less than the
Redemption Price, by one or more investment bankers or other purchasers who may
agree with the Company to purchase such Securities from the Holders, to convert
them into Common Stock of the Company and to make payment for such Securities to
the Trustee in trust for such Holders.

10.      Defaulted Interest.

                  Except as otherwise specified with respect to the Securities,
any Defaulted Interest on any Security shall forthwith cease to be payable to
the registered Holder thereof on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the Company
as provided for in Section 11.02 of the Indenture.

11.      Denominations; Transfer; Exchange.

                  The Securities are in fully registered form, without coupons,
in principal denominations of $1,000 and integral multiples of $1,000. A Holder
may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not transfer or exchange
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities in respect of which a Purchase Notice or Change in Control Purchase
Notice has been given and not withdrawn (except, in the case of a Security to be
purchased in part, the portion of the Security not to be purchased) or any
Securities for a period of 15 days before the mailing of a notice of redemption
of Securities to be redeemed.

12.      Persons Deemed Owners.

                  The registered Holder of this Security may be treated as the
owner of this Security for all purposes.

13.      Unclaimed Money or Securities.

                  The Trustee and the Paying Agent shall return to the Company
upon written request any money or securities held by them for the payment of any
amount with respect to the Securities that remains unclaimed for two years,
subject to applicable unclaimed property laws. After return to the Company,
Holders entitled to the money or

                                     A-1-12

<PAGE>

securities must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another person.

14.      Amendment; Waiver.

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
at the time outstanding and (ii) certain Defaults may be waived with the written
consent of the Holders of a majority in aggregate principal amount of the
Securities at the time outstanding. Subject to certain exceptions set forth in
the Indenture, without the consent of any Securityholder, the Company and the
Trustee may amend the Indenture or the Securities to cure any ambiguity,
omission, defect or inconsistency in this Securities or in the Indenture, or to
comply with Article 5 or Section 10.14 of the Indenture, to secure the Company's
obligations under this Security or the Indenture, to add additional Events of
Default, to increase the Conversion Rate, to add to the Company's covenants for
the benefit of the Securityholders or to surrender any right or power conferred
on the Company, to comply with any requirement of the SEC in connection with the
qualification of the Indenture under the TIA, or as necessary in connection with
the registration of the Securities under the Securities Act, to make any change
that does not materially adversely affect the rights of any Holders, to add or
change provisions as necessary to permit or facilitate the issuance of the
Global Security, to evidence and provide for the acceptance of the appointment
under the Indenture of a separate or successor Trustee, to provide additional
rights or benefits to Holders, or to modify the restrictions on, and procedures
for, resale and other transfers of this Security pursuant to law, regulation or
practice relating to the resale or transfer of restricted securities generally.

15.      Defaults and Remedies.

                  Events of Default are as set forth in Section 6.01 of the
Indenture.

                  Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to
enforce the Indenture or the Securities unless it receives indemnity or security
satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the Securities at the time outstanding
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of amounts specified in
Section 6.01(1) or (2) of the Indenture above) if a committee of its Responsible
Officers determines in good faith that withholding notice is in the interests of
the Securityholders.

16.      Trustee Dealings with the Company.

                  Subject to certain limitations imposed by the TIA, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

17.      No Recourse Against Others.

                  No past, present or future director, officer, employee, agent,
representative, member, manager, trustee, stockholder or other equity holder, as
such, of the Company, the Guarantor or any successor Person or any Affiliate of
any thereof shall have any liability for any obligations of the Company, the
Guarantor or any successor Person or any Affiliate of any thereof, either
directly or through the Company, the Guarantor or any successor Person or any
Affiliate of any thereof, under the Securities, the Indenture or the Guarantee
or for any claim based on, in respect of or by reason of such obligations or
their creation, whether by virtue of any rule of law, statute or constitutional
provision or by the enforcement of any assessment or by any legal or equitable
proceeding or otherwise. By accepting a Security, each Securityholder shall
waive and release all such liability. The waiver and release shall be part of
the consideration for the issue of the Securities.

18.      Authentication.

                  This Security shall not be valid until an authorized signatory
of the Trustee manually signs the Trustee's Certificate of Authentication on the
other side of this Security.

                               [FORM OF GUARANTEE]

                  The Guarantor (as defined in the Indenture and which term
includes any successor person under the Indenture), subject in every respect to
the terms and conditions set forth in the Indenture, hereby unconditionally
guarantees, on an unsecured basis (the "Guarantee"), to each Holder of a
Security authenticated and delivered by the Trustee in accordance with the terms
of the Indenture, and to the Trustee on behalf of such Holder, (i) (x) the due
and punctual payment of the principal of, and interest on, such Security, when
and as the same shall become due and payable, whether at Stated Maturity, by
acceleration, redemption or otherwise, (y) the due and punctual payment of
interest on the overdue principal and interest, if any, on such Security, to the
extent lawful, and (z) the faithful performance of all other obligations of the
Company to the Holders or the Trustee under such Security and the Indenture, in
each case as set forth in Article 12 of the Indenture and (ii) in case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, that the same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise.

                  The Guarantor hereby agrees to pay any and all costs and
expenses incurred by the Trustee or the Holders in enforcing their respective
rights under the Guarantee.

                  Any term or provision of the Guarantee or the Indenture
notwithstanding, the Guarantee shall not exceed the maximum amount that can be
guaranteed by the Guarantor without rendering the Guarantee voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

                  The obligations of the undersigned to the Holders of the
Securities and to the Trustee pursuant to this Guarantee and in the Indenture
are expressly set forth in the Indenture and reference is hereby made to the
Indenture for the precise terms of the Guarantee and all of the other provisions
of the Indenture to which this Guarantee relates. In the event of the assumption
by a successor Person of the obligations of the Guarantor as provided in Section
5.04 of the Indenture, such successor Person shall succeed to and be substituted
for the Guarantor hereunder and under the Indenture and all such obligations of
the Guarantor under the Indenture and the Guarantee shall terminate.

                  No past, present or future director, officer, employee, agent,
representative member, manager, trustee, stockholder or other equity holder, as
such, of the Guarantor or any successor Person or any Affiliate of the Guarantor
shall have any liability for any

                                     A-2-1

obligations of the Guarantor or any successor Person or any Affiliate of the
Guarantor, either directly or through the Guarantor or any successor Person or
any Affiliate of the Guarantor, under this Guarantee or for any claim based on,
in respect of or by reason of such obligations or their creation, whether by
virtue of any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise.

                  The Guarantee shall not be valid or obligatory for any purpose
until the certificate of authentication on the Securities shall have been
executed by the Trustee under the Indenture by the manual signature of one of
its authorized signatories.

                  The Guarantee shall be governed by and construed in accordance
with the law of the State of New York, including all matters of construction,
validity and performance, applicable to agreements made or instruments entered
into and, in each case, performed in such state.

to be duly executed.
