                          [REVERSE OF GLOBAL SECURITY]

                      2.60% Convertible Debentures due 2036

1.   Interest

     This Security shall bear cash interest at the rate of 2.60% per annum.
Interest on this Security shall accrue from the Issue Date, or from the most
recent date to which interest has been paid or provided for. Interest shall be
payable semiannually in arrears on June 15 and December 15 of each year,
beginning on June 15, 2007, to the holders of record of Securities at the close
of business on the June 1 or December 1 immediately preceding such Interest
Payment Date (or repurchase, redemption or Stated Maturity, as applicable). Each
payment of cash interest on this Security shall include interest accrued for the
period commencing on and including the immediately preceding Interest Payment
Date (or, if none, the scheduled original Issue Date) through the day before the
applicable Interest Payment Date, Redemption Date, Repurchase Date or Stated
Maturity, as applicable. Any payment required to be made on any day that is not
a Business Day shall be made on the next succeeding Business Day and no
additional interest shall accrue. Interest shall be calculated using a 360-day
year composed of twelve 30-day months. Interest shall cease to accrue on this
Security upon its Stated Maturity, conversion or repurchase by the Company
including a repurchase at the option of the Holder upon a Fundamental Change in
accordance with Paragraph 7 hereof.

     Interest on Securities converted after a Record Date but prior to the
corresponding Interest Payment Date will be paid to the Holder of the Securities
on the Record Date but, upon conversion the Holder must pay the Company the
interest which has accrued and will be paid on such Interest Payment Date. No
such payment need be made (1) if the Company has specified a Redemption Date
that is after a Record Date and on or prior to the next Interest Payment Date,
(2) if the Company has specified a Fundamental Change Repurchase Date that is
after a Record Date and on or prior to the next Interest Payment Date or (3)
only to the extent of overdue interest, if any overdue interest exists at the
time of conversion with respect to such Securities.

     From and after December 20, 2009, the Company will pay Contingent Interest
on this Security under the circumstances and in the amounts described in Article
11 of the Indenture. Such Contingent Interest, if any, shall be payable
semi-annually in arrears on each Interest Payment Date. Contingent Interest, if
any, will be computed on the basis of a 360-day year of twelve 30-day months.

     In the event of any payment of Contingent Interest, the Company will
disseminate a press release through Dow Jones & Company, Inc. or Bloomberg
Business News containing this information or through such other public medium as
the Company may use at that time.

2.   Method of Payment.

     The Company shall promptly make all payments in respect of the Securities
on the dates and in the manner provided herein and in the Indenture. The Company
will pay interest (except Defaulted Interest) on the principal amount of the
Securities on each June 15 and December 15

                                      R-1

<PAGE>

to the Persons who are registered Holders of Securities at the close of business
on the June 1 and December 1 next preceding the Interest Payment Date even if
Securities are canceled or repurchased after such Record Date and on or before
the Interest Payment Date. Holders must surrender Securities to a Paying Agent
to collect principal payments. The Company will pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts. The Company will make all payments in
respect of a Certificated Security (including principal and interest) in U.S.
dollars at the office of the Trustee. At the Company's option, however, the
Company may make such payments by mailing a check to the registered address of
each Holder thereof as such address shall appear on the register or, with
respect to Securities represented by a Global Security, by wire transfer of
immediately available funds to the accounts specified by the Depositary. If an
Interest Payment Date is a date other than a Business Day, payment may be made
at that place on the next succeeding day that is a Business Day and no interest
shall accrue for the intervening period.

3.   Paying Agent, Conversion Agent and Registrar.

     Initially, the Trustee will act as Paying Agent, Conversion Agent and
Registrar. The Company may appoint and change any Paying Agent, Conversion Agent
or Registrar without notice, other than notice to the Trustee; provided that the
Company will maintain at least one Paying Agent in the United States of America,
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 or Registrar.

4.   Indenture.

     The Company issued the Securities under an Indenture dated as of December
20, 2006 (the "Indenture"), between the Company and the Trustee. The terms of
the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as in effect from
time to time. Capitalized terms used herein and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Holders are referred to the Indenture and the TIA for a
statement of those terms.

     The Securities are general unsecured obligations of the Company limited to
an aggregate principal amount of $900,000,000. The Indenture does not limit
other indebtedness of the Company, secured or unsecured.

5.   Redemption at the Option of the Company.

     No sinking fund is provided for the Securities. Subject to the terms and
conditions of this Indenture, the Securities are redeemable at the option of the
Company in whole or in part, at any time or from time to time on, or after
December 20, 2009 for a cash price equal to the 100% of the principal amount
plus accrued and unpaid interest, if any, up to the Redemption Date (the
"REDEMPTION PRICE").

                                      R-2

<PAGE>

6.   Notice of Redemption.

     Notice of redemption pursuant to Paragraph 5 of this Security will be
mailed at least 15 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 all Securities (or portions
thereof) to be redeemed on the Redemption Date is deposited with the Paying
Agent prior to or on the Redemption Date, immediately after such Redemption Date
interest ceases to accrue on such Securities or portions thereof. Securities in
denominations larger than $1,000 of principal amount may be redeemed in part but
only in integral multiples of $1,000 of principal amount.

7.   Purchase By the Company at the Option of the Holder.

     (a) Subject to the terms and conditions of the Indenture, the Company shall
become obligated to repurchase, at the option of the Holder, all or any portion
of the Securities held by such Holder on December 15, 2009, December 15, 2011,
December 15, 2016, December 15, 2021, December 15, 2026 and December 15, 2031 or
the next Business Day following such dates to the extent such dates are not
Business Days in integral multiples of $1,000 in cash at a Repurchase Price
equal to 100% of the principal amount plus accrued and unpaid interest, if any,
on the Repurchase Date. To exercise such right, a Holder shall deliver to the
Company a Repurchase 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 Repurchase Date until the close of business on the
last Business Day prior to such Repurchase Date, and shall deliver the
Securities to the Paying Agent as set forth in the Indenture.

     (b) At the option of the Holder and subject to the terms and conditions of
the Indenture, the Company shall become obligated to offer to repurchase the
Securities held by such Holder within 30 days (which repurchase shall occur no
more than 45 days after the date of such offer) after the occurrence of a
Fundamental Change of the Company (as defined in the Indenture) for a
Fundamental Change Repurchase Price equal to 100% of the principal amount plus
accrued and unpaid interest, if any, on the Fundamental Change Repurchase Date,
which Fundamental Change Repurchase Price shall be paid in cash.

     (c) Holders have the right to withdraw any Repurchase Notice delivered
pursuant to Paragraph 7(a) above or Fundamental Change Repurchase Notice
delivered pursuant to Paragraph 7(b), as the case may be, by delivering to the
Paying Agent a written notice of withdrawal in accordance with the provisions of
the Indenture at any time prior to the close of business of the last day prior
to the Repurchase Date. If cash sufficient to pay the Repurchase Price or
Fundamental Change Repurchase Price, as the case may be, of all Securities or
portions thereof to be repurchased as of the Repurchase Date or the Fundamental
Change Repurchase Date, as the case may be, is deposited with the Paying Agent
on the Repurchase Date or the Fundamental Change Repurchase Date, interest will
cease to accrue on such Securities (or portions thereof) immediately after such
Repurchase Date or Fundamental Change Repurchase Date, and the Holder thereof
shall have no other rights as such other than the right to receive the
Repurchase Price or Fundamental Change Repurchase Price upon surrender of such
Security.

8.   Conversion.

     (a) The initial Conversion Rate is 16.1875 shares of Common Stock per
$1,000 principal amount, subject to adjustment in certain events described in
the Indenture. Upon conversion, a Holder will receive, in respect of each $1,000
principal amount of Securities, (x) cash equal to the lesser of (1) $1,000 or
(2) the Conversion Value; and (y) a number of shares of Common Stock equal the
sum of the Daily Share Amounts (as defined in the Indenture) for each of the ten
consecutive Trading Days in the Applicable Conversion Reference Period (as
defined in the Indenture), as more fully set forth in the Indenture. A Holder
that surrenders Securities for conversion will receive cash in lieu of any
fractional share of Common Stock based on the Closing Sale Price of the Common
Stock of the Company on the Trading Day immediately prior to the Conversion
Date.

     (b) Holders may surrender Securities for conversion into cash and shares,
if any, of Common Stock during any fiscal quarter ending after March 31, 2007
(and only during such fiscal quarter) if, the Closing Sale Price of the Common
Stock for at least 20 Trading Days in the 30 Trading Day period ending on the
last Trading Day of the immediately preceding fiscal quarter is more than 130%
of the Conversion Price per share of the Common Stock on the last day of such
preceding fiscal quarter. The "CONVERSION PRICE" per share of Common Stock as of
any day will equal the result obtained by dividing $1,000 by the then applicable
Conversion Rate.

     (c) A Holder may also surrender for conversion a Security or portion of a
Security which has been called for redemption pursuant to Paragraph 5 hereof,
and such Securities may be surrendered for conversion until the close of
business on the Business Day prior to the Redemption Date. A Security in respect
of which a Holder has delivered a Repurchase Notice or a Fundamental Change
Repurchase Notice exercising the option of such Holder to require the Company to
repurchase such Security may be converted only if such notice of exercise is
withdrawn in accordance with the terms of the Indenture.

     (d) If the Company elects to either (i) distribute to all Holders of Common
Stock certain rights entitling them to purchase, for a period expiring within 60
days, shares of Common Stock at less than the current market price at the time,
or (ii) distribute to all Holders of Common Stock the Company's assets, debt
securities or certain rights to purchase the Company's securities, which
distribution has a per share value exceeding 12.5% of the Closing Sale Price of
a share of Common Stock on the day prior to the declaration date for such
distribution, the Company must give notice to the Holders at least 25 scheduled
Trading Days prior to the Ex-Dividend Date for such distribution. Once such
notice has been given, the Securities may be surrendered for conversion at any
time until the earlier of the close of business on the Business Day prior to the
Ex-Dividend Date or until the Company announces that such distribution will not
take place. No adjustment to the ability of a holder to convert will be made if
the holder will otherwise participate in the distribution without conversion.
The Company shall notify Holders at least 25 scheduled Trading Days prior to the
Ex-Dividend Date for such distribution.

     (e) If the Company is party to any transaction or event that constitutes a
Fundamental Change, including any event that would be a Fundamental Change but
for the existence of an exception specified in clauses (A) or (B) of the
paragraph following the definition thereof), a

                                      R-4

<PAGE>

Holder may surrender Securities for conversion at any time from and after the
15th scheduled Trading Day prior to the anticipated effective date of such
transaction or event until the Fundamental Change Repurchase Date (or if there
is no Fundamental Change Repurchase Date with respect to such event, the 15th
day after the effective date thereof, as set forth in Section 3.08 of the
Indenture) corresponding to such event. The Company will notify Holders at least
25 scheduled Trading Days prior to the anticipated effective date of such
transaction.

     (f) If the Company is a party to a combination, merger, binding share
exchange or sale or conveyance of all or substantially all of its property and
assets, in each case pursuant to which the Common Stock would be converted into
cash, securities and/or other property that does not also constitute Fundamental
Change, including any event that would be a Fundamental Change but for the
existence of an exception specified in clauses (A) or (B) of the paragraph
following the definition thereof), Holders shall have the right to surrender
Securities for conversion at any time from and after the date which is 15
scheduled Trading Days prior to the date that is the actual effective date of
such transaction and ending on the 15th scheduled Trading Day following the
effective date of such transaction. The Company will notify Holders at least 25
scheduled Trading Days prior to the anticipated effective date of such
transaction.

     (g) Holders may surrender Securities for conversion at any time on or after
September 15, 2036 until the close of business on the business day immediately
preceding the Stated Maturity.

     (h) To surrender a Security for conversion, a Holder must (1) complete and
manually sign the irrevocable 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 and (4) pay any transfer or
similar tax, if required.

     (i) 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 shares of Common Stock except as
provided in the Indenture. Except as provided in Paragraph 1 hereof, on
conversion of a Security, the Holder will not receive any cash payment
representing accrued and unpaid interest with respect to the converted
Securities. Instead, upon conversion the Company will deliver to the Holder
cash, a fixed number of shares of Common Stock, if any, and any cash payment to
account for fractional shares. Accrued and unpaid interest will be deemed paid
in full rather than cancelled, extinguished or forfeited. The Company will not
adjust the Conversion Rate to account for accrued and unpaid interest.

     (j) The Conversion Rate will be adjusted as provided in Article 10 of the
Indenture. The Company may increase the Conversion Rate for at least 20 Business
Days, so long as the increase is irrevocable during such period.

     (k) 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 as set forth in
Section 5.01 of the Indenture, or upon certain events described in Section 10.15
of the Indenture, then at the effective time of the transaction, the Conversion
Value and Daily Share Amount will be determined based upon the

                                      R-5

<PAGE>

kind and amount of cash, securities or other property that a holder of a number
of shares of Common Stock equal to the Conversion Rate would have received in
the transaction or event.

     (l) The Company will notify Holders of any event triggering the right to
convert the Securities as specified in the Indenture.

9.   Conversion Arrangement on Call for Redemption.

     A Holder may surrender for conversion any of the Securities called for
redemption at any time prior to the close of business one Business Day prior to
the Redemption Date, even if it is not otherwise convertible at such time. If a
Holder has already delivered a Repurchase Notice or a Fundamental Change
Repurchase Notice with respect to a Security, however, the Holder may not
surrender that Security for conversion until the Holder has withdrawn the notice
in accordance with the Indenture.

10.  Mandatory Disposition Due to Gaming Laws.

     Each holder, by accepting this Security, shall be deemed to have agreed
that if the Gaming Authority of any jurisdiction in which Company or any
Subsidiary does business requires that a person who is a holder or the
beneficial owner of the Security be licensed, qualified or found suitable under
applicable Gaming Laws, such holder or beneficial owner, as the case may be,
shall apply for a license, qualification or a finding of suitability within the
required time period. If such person fails to apply or become licensed or
qualified or is found unsuitable, the Company shall have the right, at its
option to:

     (1) require such person to dispose of this Security or beneficial interest
in this Security within 30 days of receipt of notice of the Company's election
or such earlier date as may be requested or prescribed by such Gaming Authority;
or

     (2) redeem this Security at a redemption price equal to:

          (A) the lesser of

               (i) such person's cost, and

               (ii) the principal amount, plus accrued and unpaid interest, if
          any, to the earlier of the redemption date or the date of the finding
          of unsuitability, which may be less than 30 days following the notice
          of redemption if so required or prescribed by the applicable Gaming
          Authority; or

          (B) such other amount as may be required by applicable law or by order
     of any applicable Gaming Authority.

     The Company shall notify the Trustee in writing of any such redemption as
soon as practicable. The Company shall not be responsible for any costs or
expenses any such holder may incur in connection with its application for a
license, qualification or a finding of suitability.

                                      R-6

11.  Denominations; Transfer; Exchange.

     The Securities are in fully registered form, without coupons, in
denominations of $1,000 of principal amount 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 Repurchase Notice or Fundamental Change
Repurchase Notice has been given and not withdrawn (except, in the case of a
Security to be repurchased in part, the portion of the Security not to be
repurchased) 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 law. After return to the Company, Holders entitled
to the money or securities must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another Person.

14.  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.

15.  Calculations in Respect of Securities.

     The Company will be responsible for making all calculations called for
under the Securities. These calculations include, but not limited to,
determinations of the market prices of the Securities and the Common Stock, any
accrued interest payable on the Securities, the Conversion Value, the Daily
Share Amount and the Conversion Price of the Securities. The Company will make
these calculations in good faith and, absent manifest error, the calculations
will be final and binding on Holders of the Securities. The Company will provide
to the Trustee a schedule of its calculations, and the Trustee is entitled to
rely upon the accuracy of such calculations without independent verification.
The Trustee will forward the Company's calculations to any Holder of the
Securities upon the request of such Holder.

                                      R-7

<PAGE>

16.  No Recourse Against Others.

     A director, officer, employee or shareholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Securities
or the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Holder waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

17.  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.

18.  Abbreviations.

     Customary abbreviations may be used in the name of a Holder or an assignee,

calendar days following the Closing Date; provided, however, that the Company
may, upon written notice to all Holders, postpone having the Shelf Registration
Statement become effective for a reasonable period not to exceed 90 days if the
Company possesses material non-public information, the disclosure of which would
have a material adverse effect on the Company and its subsidiaries taken as a
whole or would impede the consummation of a proposed or pending material

                                       4

<PAGE>

     (b) The Company shall use its reasonable best efforts:

          (i) to keep the Shelf Registration Statement continuously effective,
     supplemented and amended as required by the provisions of Section 3(j)
     hereto, in order to permit the Prospectus forming a part thereof and any
     related Issuer Free Writing Prospectus to be usable by Electing Holders

     under the Shelf Registration Statement; (2) the expiration of the period
     referred to in Rule 144(k) of the Act with respect to all Registrable
     Securities held by Persons that are not Affiliates of the Company; (3) two
     years from the last date of original issuance of any Registrable
     Securities; and (4) the date when there are no Registrable Securities
     outstanding (such period being referred to herein as the "Effectiveness
     Period");

          (ii) after the Effective Time of the Shelf Registration Statement,
     promptly upon the request of any Holder of Registrable Securities that is
     not then an Electing Holder, to take any action reasonably necessary (other
     than the preparation and filing of any post effective amendment, if at such
     time the Company is eligible to use an automatic shelf registration
     statement and to supplement such automatic shelf registration statement by
     prospectus supplement) to enable such Holder to use the Prospectus forming
     a part thereof and any related Issuer Free Writing Prospectus for resales
     of Registrable Securities, including, without limitation, any action
     necessary to identify such Holder as a selling securityholder in the Shelf
     Registration Statement; provided, however, that nothing in this
     subparagraph shall relieve such Holder of the obligation to return a
     completed and signed Notice and Questionnaire to the Company in accordance
     with Section 3(a)(ii) hereof; and

          (iii) if at any time the Securities, pursuant to Article 10 of the
     Indenture, are convertible into securities other than Common Stock, to
     cause, or to cause any successor under the Indenture to cause, such
     securities to be included in the Shelf Registration Statement no later than
     the date on which the Securities may then be convertible into such
     securities.

The Company shall be deemed not to have used its reasonable best efforts to keep
the Shelf Registration Statement effective during the Effectiveness Period if
the Company voluntarily takes any action that would result in Holders of
Registrable Securities covered thereby not being able to offer and sell any of
such Registrable Securities during that period, unless such action is (A)
required by applicable law and the Company thereafter promptly complies with the
requirements of paragraph 3(j) below or (B) permitted pursuant to Section 2(c)
below.

     (c) The Company may suspend the use of the Prospectus for a period not to
exceed 45 days in any 90-day period or an aggregate of 90 days in any 12-month
period, during the period beginning on the issue date and ending on or prior to
the second anniversary of the last

                                       5

<PAGE>

issue date of any Debentures (each, a "Suspension Period") if the Board of
Directors of the Company shall have determined in good faith that because of
valid business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, pending
corporate developments and similar events, it is in the best interests of the
Company to suspend such use, and prior to suspending such use the Company
provides the Electing Holders with written notice of such suspension, which
notice need not specify the nature of the event giving rise to such suspension.

     3. Registration Procedures. In connection with the Shelf Registration
Statement, the following provisions shall apply:

          (a) (i) Not less than 30 calendar days prior to the Effective Time of
     the Shelf Registration Statement, the Company shall mail the Notice and
     Questionnaire to the Holders of Registrable Securities. Holders of
     Registrable Securities shall have at least 20 calendar days from the date
     on which the Notice and Questionnaire is first mailed to such Holders to
     return a completed and signed Notice and Questionnaire to the Company. The
     Company shall take action to name each Holder that is a Electing Holder as
     of the date that is five business days prior to the effectiveness of the
     Shelf Registration Statement as a selling securityholder in the Shelf
     Registration Statement at the time of its effectiveness so that such Holder
     is permitted to deliver the Prospectus forming a part thereof as of such
     time to purchasers of such Holder's Registrable Securities in accordance
     with applicable law. The Company shall not be required to take any action
     to name any Holder as a selling securityholder in the Shelf Registration
     Statement or to enable any Holder to use the Prospectus forming a part
     thereof for resales of Registrable Securities unless such Holder has
     returned a completed and signed Notice and Questionnaire to the Company by
     the deadline set forth herein prior to the Effective Time or after the
     Effective Time as specified below.

          (ii) After the Effective Time of the Shelf Registration Statement, the
     Company shall, upon the request of any Holder of Registrable Securities
     that is not then an Electing Holder, promptly send a Notice and
     Questionnaire to such Holder. From and after the Effective Time of the
     Shelf Registration Statement, the Company shall (A) as promptly as is
     practicable after the date a completed and signed Notice and Questionnaire
     is delivered to the Company, and in any event within five Business Days
     after such date, prepare and file with the Commission (x) a supplement to
     the Prospectus or, if required by applicable law, a post-effective
     amendment to the Shelf Registration Statement and (y) any other document
     required by applicable law, so that the Holder delivering such Notice and
     Questionnaire is named as a selling securityholder in the Shelf
     Registration Statement and is permitted to deliver the Prospectus to
     purchasers of such Holder's Registrable Securities in accordance with
     applicable law, and (B) if the Company shall file a post-effective
     amendment to the Shelf Registration Statement, use its reasonable best
     efforts to cause such post-effective amendment to become effective under
     the Securities Act as

                                       6

<PAGE>

     promptly as is practicable; provided, however, that if a Notice and
     Questionnaire is delivered to the Company during a Suspension Period, the
     Company shall not be obligated to take the actions set forth in this clause
     (ii) until the termination of such suspension period; and provided,
     further, that any supplements or amendments that solely list an additional
     Electing Holder need not be submitted for prior review of counsel to
     Electing Holders under Section 3(c) below.

          (iii) The term "Electing Holder" shall mean any Holder of Registrable
     Securities that has returned a completed and signed Notice and
     Questionnaire to the Company in accordance with Section 3(a)(i) or 3(a)(ii)
     hereof.

     (b) The Company shall furnish to one counsel for the Electing Holders which
counsel shall initially be Cleary Gottlieb Steen & Hamilton LLP, prior to the
Effective Time, a copy of the Shelf Registration Statement initially filed with
the Commission, and shall furnish to Electing Holders upon request, prior to the
filing thereof with the Commission, copies of each amendment thereto, each
amendment or supplement, if any, to the Prospectus included therein, and any
related Issuer Free Writing Prospectus and shall use its reasonable best efforts
to reflect in each such document, at the Effective Time or when so filed with
the Commission, as the case may be, such comments as such Holders and their
counsel reasonably may propose.

     (c) The Company shall promptly take such action as may be necessary so that
(i) each of the Shelf Registration Statement and any amendment thereto, the
Prospectus forming a part thereof and any amendment or supplement thereto and
any related Issuer Free Writing Prospectus (and each report or other document
incorporated therein by reference in each case) complies in all material
respects with the Securities Act and the Exchange Act and the respective rules
and regulations thereunder, (ii) each of the Shelf Registration Statement and
any amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) each of the Prospectus forming a part of the Shelf Registration Statement,
any amendment or supplement to such Prospectus, and any related Issuer Free
Writing Prospectus does not at any time during the Effectiveness Period include
an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     (d) The Company shall promptly advise each Electing Holder:

          (i) when a Shelf Registration Statement and any amendment thereto has
     been filed with the Commission and when a Shelf Registration Statement or
     any post-effective amendment thereto has become effective, in each case by
     making a public announcement thereof by release made to Dow Jones &
     Company, Inc., Bloomberg Business News or PR Newswire;

                                       7

<PAGE>

          (ii) of any request by the Commission for amendments or supplements to
     the Shelf Registration Statement or the Prospectus included therein or for
     additional information;

          (iii) of the issuance by the Commission of any stop order suspending
     the effectiveness of the Shelf Registration Statement or the initiation of
     any proceedings for such purpose;

          (iv) of the receipt by the Company of any notification with respect to
     the suspension of the qualification of the securities included in the Shelf
     Registration Statement for sale in any jurisdiction or the initiation of
     any proceeding for such purpose; and

          (v) of the happening of any event or the existence of any state of
     facts that requires the making of any changes in the Shelf Registration
     Statement or the Prospectus included therein or any related Issuer Free
     Writing Prospectus so that, as of such date, such Shelf Registration
     Statement, Prospectus and any such Issuer Free Writing Prospectus do not
     contain an untrue statement of a material fact and do not omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein (in the case of the Prospectus and any such Issuer Free
     Writing Prospectus, in light of the circumstances under which they were
     made) not misleading (which advice shall be accompanied by an instruction
     to such Holders to suspend the use of the Prospectus or Issuer Free Writing
     Prospectus until the requisite changes have been made which notice need not
     specify the nature of the event giving rise to such suspension).

     (e) The Company shall use its reasonable best efforts to prevent the
issuance, and if issued to obtain the withdrawal at the earliest possible time,
of any order suspending the effectiveness of the Shelf Registration Statement.

     (f) The Company shall furnish to each Electing Holder, upon their request,
without charge, at least one copy of the Shelf Registration Statement, all
post-effective amendments any prospectus supplement thereto, including any
financial statements and schedules included therein, and, if such Electing
Holder so requests in writing, all reports, other documents and exhibits that
are filed with or incorporated by reference in the Shelf Registration Statement
that are not at such time available on the SEC's Electronic Data Gathering,
Analysis, and Retrieval system.

     (g) The Company shall, during the Effectiveness Period, make available to
each Electing Holder, without charge, as many copies of the Prospectus
(including each preliminary Prospectus) included in the Shelf Registration
Statement, any related Issuer Free Writing Prospectus, and, in each case, any
amendment or supplement thereto as such Electing Holder may reasonably request;
and the Company consents (except during a Suspension Period or during the
continuance of any event or the existence of any state of facts described in
Sections

                                       8

Writing Prospectus and, in each case, any amendment or supplement thereto during
the Effectiveness Period.

Statement, and (iii) take any and all other actions necessary or advisable to
enable the disposition in such jurisdictions of such Registrable Securities;

subject.

preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to the Shelf Registration Statement, which certificates, if so
required by any securities exchange upon which any Registrable Securities are
listed, shall be penned, lithographed or engraved, or produced by any
combination of such methods, on steel engraved borders, and which certificates
shall be free of any restrictive legends and in such permitted denominations and
registered in such names as Electing Holders may request in connection with the
sale of Registrable Securities pursuant to the Shelf Registration Statement.

     (j) Upon the occurrence of any fact or event contemplated by paragraph
3(d)(v) above, subject to Section 2(c) hereof, the Company shall promptly
following such occurrence prepare, file (and have become effective) a
post-effective amendment to any Shelf Registration Statement or an amendment or
supplement to the related Prospectus included therein or file any other document
with the Commission so that, as thereafter delivered to purchasers of the
Registrable Securities, the Prospectus and any related Issuer Free Writing
Prospectus will not include an untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. If the Company
notifies the Electing Holders of the occurrence of any fact or event
contemplated by paragraph 3(d)(v) above or of a Suspension Period, the Electing
Holder shall

                                       9

<PAGE>

suspend the use of the Prospectus and any related Issuer Free Writing Prospectus
until the requisite changes to the Prospectus or the Issuer Free Writing
Prospectus have been made.

     (k) Not later than the Effective Time of the Shelf Registration Statement,
the Company shall provide a CUSIP number for the Registrable Securities that are
debt securities.

     (l) The Company shall use its reasonable best efforts to comply with all
applicable Rules and Regulations, and to make generally available to its
securityholders as soon as practicable, but in any event not later than eighteen
months after (i) the effective date (as defined in Rule 158(c) under the
Securities Act) of the Shelf Registration Statement, (ii) the effective date of
each post-effective amendment to the Shelf Registration Statement, and (iii) the
date of each filing by the Company with the Commission of an Annual Report on
Form 10-K that is incorporated by reference in the Shelf Registration Statement,
an earnings statement of the Company and its subsidiaries complying with Section
11(a) of the Securities Act and the rules and regulations of the Commission
thereunder (including, at the option of the Company, Rule 158).

     (m) Not later than the Effective Time of the Shelf Registration Statement,
the Company shall cause the Indenture to be qualified under the Trust Indenture
Act; in connection with such qualification, the Company shall cooperate with the
Trustee under the Indenture and the Holders (as defined in the Indenture) to
effect such changes to the Indenture as may be required for such Indenture to be
so qualified in accordance with the terms of the Trust Indenture Act; and the
Company shall execute, and shall use all reasonable efforts to cause the Trustee
to execute, all documents that may be required to effect such changes and all
other forms and documents required to be filed with the Commission to enable
such Indenture to be so qualified in a timely manner. In the event that any such
amendment or modification referred to in this Section 3(m) involves the
appointment of a new trustee under the Indenture, the Company shall appoint a
new trustee thereunder pursuant to the applicable provisions of the Indenture.

     (n) In the event of an underwritten offering conducted pursuant to Section
6 hereof, the Company shall, if requested, promptly include or incorporate in a
Prospectus supplement or post-effective amendment to the Shelf Registration
Statement such information as the Managing Underwriters and the Company
reasonably agree should be included therein and shall make all required filings
of such Prospectus supplement or post-effective amendment as soon as practicable
after it is notified of the matters to be included or incorporated in such
Prospectus supplement or post-effective amendment.

     (o) The Company shall enter into such customary agreements (including an
underwriting agreement in customary form in the event of an underwritten
offering conducted pursuant to Section 6 hereof (which will include lock-up
agreements only if the Company so agrees) and take all other appropriate action
in order to expedite and facilitate the registration and disposition of the
Registrable Securities, and in connection therewith, if an underwriting

                                       10

<PAGE>

agreement is entered into, cause the same to contain indemnification provisions
and procedures substantially identical to those set forth in Section 5 hereof
with respect to all parties to be indemnified pursuant to Section 5 hereof.

     (p) The Company shall:

          (i) (A) subject to the provisions of this paragraph, make reasonably
     available for inspection during normal business hours by the Electing
     Holders, any underwriter participating in any disposition pursuant to the
     Shelf Registration Statement, and any attorney or accountant or other agent
     retained by such Electing Holders or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and its subsidiaries, and (B) cause the Company's officers,
     directors and employees to supply all information reasonably requested by
     such Electing Holders or any such underwriter, attorney or accountant or
     agent in connection with the Shelf Registration Statement, in each case, as
     is customary for similar due diligence examinations; provided, however,
     that all records, information and documents that are designated by the
     Company, in good faith, as confidential shall be kept confidential by such
     Electing Holders and any such underwriter, attorney or accountant or agent,
     unless such disclosure is made in connection with a court proceeding or
     required by law, or such records, information or documents become available
     to the public generally or through a third party without an accompanying
     obligation of confidentiality and the Company may request that the Electing
     Holders agree in writing to maintain the confidentiality of information
     obtained in such due diligence examination; and provided, further, that,
     such inspection and information gathering shall be coordinated on behalf of
     the Electing Holders and the other parties entitled thereto by one counsel
     designated by and on behalf of the Electing Holders and other parties;

          (ii) in connection with any underwritten offering conducted pursuant
     to Section 6 hereof, make such representations and warranties to the
     Electing Holders participating in such underwritten offering and to the
     Managing Underwriters, in form, substance and scope as are customarily made
     by the Company to underwriters in primary underwritten offerings of equity
     and convertible debt securities and covering matters including, but not
     limited to, those set forth in the Purchase Agreement;

          (iii) in connection with any underwritten offering conducted pursuant
     to Section 6 hereof, obtain opinions of counsel to the Company (which
     counsel and opinions (in form, scope and substance) shall be reasonably
     satisfactory to the Managing Underwriters) addressed to each Electing
     Holder participating in such underwritten offering and the underwriters,
     covering such matters as are customarily covered in opinions requested in
     primary underwritten offerings of equity and convertible debt securities
     and such other matters as may be reasonably requested by such Electing
     Holders and underwriters (it being agreed that the matters to be covered by
     such opinions

                                       11

<PAGE>

     shall include, without limitation, as of the date of the opinion and as of
     the Effective Time of the Shelf Registration Statement or most recent
     post-effective amendment thereto, as the case may be, the absence from the
     Shelf Registration Statement, the Prospectus and any related Issuer Free
     Writing Prospectus, in each case, including the documents incorporated by
     reference therein, of an untrue statement of a material fact or the
     omission of a material fact required to be stated therein or necessary to
     make the statements therein (in the case of the Prospectus and any such
     Issuer Free Writing Prospectus, in light of the circumstances under which
     they were made) not misleading;

          (iv) in connection with any underwritten offering conducted pursuant
     to Section 6 hereof, obtain "cold comfort" letters and updates thereof from
     the independent public accountants of the Company (and, if necessary, from
     the independent public accountants of any subsidiary of the Company or of
     any business acquired by the Company for which financial statements and
     financial data are, or are required to be, included in the Shelf
     Registration Statement), addressed to each Electing Holder participating in
     such underwritten offering (if such Electing Holder has provided such
     letter, representations or documentation, if any, required by the
     accountants for such "cold comfort" letter to be so addressed) and the
     underwriters, in customary form and covering matters of the type
     customarily covered in "cold comfort" letters in connection with primary
     underwritten offerings;

          (v) in connection with any underwritten offering conducted pursuant to
     Section 6 hereof, deliver such documents and certificates as are customary
     and may be reasonably requested by counsel to the Electing Holders
     participating in such underwritten offering and the Managing Underwriters,
     if any, including, without limitation, certificates to evidence compliance
     with Section 3(j) hereof and with any conditions contained in the
     underwriting agreement or other agreements entered into by the Company.

     (q) The Company will use its best efforts to cause the Common Stock
issuable upon conversion of the Securities to be listed on the New York Stock
Exchange or other stock exchange or trading system on which the Common Stock
primarily trades on or prior to the Effective Time of the Shelf Registration
Statement hereunder.

     (r) In the event that any broker-dealer registered under the Exchange Act
shall be an "affiliate" (as defined in Rule 2720(b)(1) of the NASD Rules (or any
successor provision thereto)) of the Company or has a "conflict of interest" (as
defined in Rule 2720(b)(7) of the NASD Rules (or any successor provision
thereto)) and such broker-dealer shall underwrite, participate as a member of an
underwriting syndicate or selling group or assist in the distribution of any
Registrable Securities covered by the Shelf Registration Statement, whether as a
Holder of such Registrable Securities or as an underwriter, a placement or sales
agent or a broker or dealer in respect thereof, or otherwise, the Company shall
assist such broker-dealer in complying

                                       12

<PAGE>

with the requirements of the NASD Rules, including, without limitation, by (A)
engaging a "qualified independent underwriter" (as defined in Rule 2720(b)(15)
of the NASD Rules (or any successor provision thereto)) to participate in the
preparation of the registration statement relating to such Registrable
Securities, to exercise usual standards of due diligence in respect thereto and
to recommend the public offering price of such Registrable Securities, (B)
indemnifying such qualified independent underwriter to the extent of the
indemnification of underwriters provided in Section 5 hereof, and (C) providing
such information to such broker-dealer as may be required in order for such
broker-dealer to comply with the requirements of the NASD Rules.

     (s) The Company shall use its reasonable best efforts to take all other
steps necessary to effect the registration, offering and sale of the Registrable
Securities covered by the Shelf Registration Statement contemplated hereby.

     4. Registration Expenses. Except as otherwise provided in Section 3, the
Company shall bear all fees and expenses incurred in connection with the
performance of its obligations under Sections 2, 3 and 6 hereof and shall bear
or reimburse the Electing Holders for the reasonable fees and disbursements of a
single counsel selected by a plurality of all Electing Holders who own an
aggregate of not less than 25% of the aggregate principal amount of the
Registrable Securities covered by the Shelf Registration Statement, or
designated by the Purchasers if Electing Holders have not so designated, to act
as counsel for all the Electing Holders in connection therewith. Each Electing
Holder shall pay all underwriting discounts and commissions and transfer taxes,
if any, relating to the sale or disposition of such Electing Holder's
Registrable Securities pursuant to the Shelf Registration Statement.

     5. Indemnification and Contribution.

     (a) Indemnification by the Company. Upon the registration of the
Registrable Securities pursuant to Section 2 hereof, the Company shall indemnify
and hold harmless each Electing Holder and each underwriter, if any, and each of
their respective officers and directors and each person who controls such
Electing Holder or underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act (each such person being
sometimes referred to as an "Indemnified Person") against any losses, claims,
damages or liabilities, joint or several, to which such Indemnified Person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act, or any Prospectus or
related Issuer Free Writing Prospectus contained therein or furnished by the
Company to any Indemnified Person, or, in each case, any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading,

                                       13

<PAGE>

and the Company hereby agrees to reimburse such Indemnified Person for any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such action or claim as such expenses are incurred; provided,
however, that the Company shall not be liable to any such Indemnified Person in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in such Shelf Registration Statement,
Prospectus or related Issuer Free Writing Prospectus, or, in each case,
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by such Indemnified Person expressly for
use therein; and provided, further, that the Company shall not be liable for
loss, claim, damage or expense arising from any offer or sale of Registrable
Securities during a Suspension Period of which the Electing Holder has received
notice.

     (b) Indemnification by the Electing Holders and any Agents and
Underwriters. Each Electing Holder agrees, as a consequence of the inclusion of
any of such Electing Holder's Registrable Securities in such Shelf Registration
Statement, and each underwriter, selling agent or other securities professional,
if any, which facilitates the disposition of Registrable Securities shall agree,
as a consequence of facilitating such disposition of Registrable Securities,
severally and not jointly, to (i) indemnify and hold harmless the Company, its
directors, officers who sign any Shelf Registration Statement and each person,
if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any losses, claims,
damages or liabilities to which the Company or such other persons may become
subject, under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in such Shelf Registration Statement or Prospectus, or any amendment
or supplement, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Electing
Holder, underwriter, selling agent or other securities professional expressly
for use therein, and (ii) reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
any such action or claim as such expenses are incurred.

     (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party
under subsection (a) or (b) above of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under this Section 5, notify such indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability under subsection (a)
or (b) above except to the extent it has been materially prejudiced by such
failure, or any liability, which it may have to any indemnified party otherwise
than under the indemnification provisions of or contemplated by subsection (a)
or (b) above. In no event shall the indemnifying party be

                                       14

<PAGE>

liable for the fees and expenses of more than one counsel (other than local
counsel) for all indemnified parties in connection with any one action or
separate but similar actions in the same jurisdiction arising out of the same
general allegations or circumstances. In case any such action shall be brought
against Holders, such counsel shall be designated by a plurality of all such
Holders who own an aggregate of not less than 25% of the aggregate principal
amount of Registrable Securities. In case any such action shall be brought
against any indemnified party and it shall notify an indemnifying party of the
commencement thereof, such indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, such indemnifying party shall
not be liable to such indemnified party under this Section 5 for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act, by
or on behalf of any indemnified party.

     (d) Contribution. If the indemnification provided for in this Section 5 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 5(d) were determined by
pro rata allocation (even if the Electing Holders or any underwriters, selling
agents or other securities professionals or all of them 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 in this Section 5(d).
The

                                       15

<PAGE>

amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
shall be deemed to include any legal or other fees or expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. 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. The obligations of the Electing Holders and any underwriters,
selling agents or other securities professionals in this Section 5(d) to
contribute shall be several in proportion to the percentage of principal amount
of Registrable Securities registered or underwritten, as the case may be, by
them and not joint.

     (e) Notwithstanding any other provision of this Section 5, in no event will
any (i) Electing Holder be required to undertake liability to any person under
this Section 5 for any amounts in excess of the dollar amount of the proceeds to
be received by such Holder from the sale of such Holder's Registrable Securities
(after deducting any fees, discounts and commissions applicable thereto)
pursuant to any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act and (ii) underwriter,
selling agent or other securities professional be required to undertake
liability to any person hereunder for any amounts in excess of the discount,
commission or other compensation payable to such underwriter, selling agent or
other securities professional with respect to the Registrable Securities
underwritten by it and distributed to the public.

     (f) The obligations of the Company under this Section 5 shall be in
addition to any liability which the Company may otherwise have to any
Indemnified Person and the obligations of any Indemnified Person under this
Section 5 shall be in addition to any liability which such Indemnified Person
may otherwise have to the Company. The remedies provided in this Section 5 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to an indemnified party at law or in equity.

     6. Underwritten Offering. Any Holder of Registrable Securities who desires
to do so may sell Registrable Securities (in whole or in part) in an
underwritten offering; provided that (i) the Electing Holders of at least
33-1/3% in aggregate principal amount of the Registrable Securities then covered
by the Shelf Registration Statement shall request such an offering) and (ii) at
least such aggregate principal amount of such Registrable Securities shall be
included in such offering; and provided, further, that the Company shall not be
obligated to cooperate with more than one underwritten offering during the
Effectiveness Period. Upon receipt of such a request, the Company shall provide
all Holders of Registrable Securities written notice of the request, which
notice shall inform such Holders that they have the opportunity to participate
in the offering. In any such underwritten offering, the investment banker or
bankers and manager or managers that will administer the offering will be
selected by, and the underwriting arrangements with respect thereto (including
the size of the offering) will be approved by, the holders of a majority of the
Registrable Securities to be included in such offering; provided,

                                       16
<PAGE>

however, that such investment bankers and managers and underwriting arrangements
must be reasonably satisfactory to the Company. No Holder may participate in any
underwritten offering contemplated hereby unless (a) such Holder agrees to sell
such Holder's Registrable Securities to be included in the underwritten offering
in accordance with any approved underwriting arrangements, (b) such Holder
completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such approved underwriting arrangements, and (c) if
such Holder is not then an Electing Holder, such Holder returns a completed and
signed Notice and Questionnaire to the Company in accordance with Section
3(a)(ii) hereof within a reasonable amount of time before such underwritten
offering. The Holders participating in any underwritten offering shall be
responsible for any underwriting discounts and commissions and fees and, subject
to Section 4 hereof, expenses of their own counsel. The Company shall pay all
expenses customarily borne by issuers in an underwritten offering, including but
not limited to filing fees, the fees and disbursements of its counsel and
independent public accountants and any printing expenses incurred in connection
with such underwritten offering. Notwithstanding the foregoing or the provisions
of Section 3(n) hereof, upon receipt of a request from the Managing Underwriter
or a representative of Holders of a majority of the Registrable Securities to be
included in an underwritten offering to prepare and file an amendment or
supplement to the Shelf Registration Statement and Prospectus in connection with
an underwritten offering, the Company may delay the filing of any such amendment
or supplement for up to 90 days if the Board of Directors of the Company shall
have determined in good faith that the Company has a bona fide business reason
for such delay.

     7. Additional Interest.

     (a) Notwithstanding any postponement of the effectiveness pursuant to
Section 2(a) hereof, if (i) on or prior to the 90th day following the Closing
Date, a Shelf Registration Statement has not been filed with the Commission,
(ii) on or prior to the 180th day following the Closing Date, such Shelf
Registration Statement has not become effective or (iii) if, after the
effectiveness date of the Shelf Registration Statement, (x) the Shelf
Registration Statement ceases to be effective or usable for the offer and sale
of Registrable Securities (other than due to a Suspension Period), and the
Company fails to file (and have become effective,), within 10 Business Days, a
post-effective amendment to the Shelf Registration Statement or amendment or
supplement to the Prospectus contained therein or such other document with the
Commission to make the Shelf Registration Statement effective or such Prospectus
usable, or (y) Suspension Periods exceed 45 days, whether or not consecutive, in
any 90-day period, or more than 90 days, whether or not consecutive, during any
12-month period during the Effectiveness Period (each, a "Registration
Default"), the Company shall be required to pay additional interest ("Additional
Interest"), from and including the day following such Registration Default until
such Registration Default is cured, at a rate per annum equal to one-quarter of
one percent (0.25%) of the aggregate principal amount of the Debentures, to and
including the 90th day following such

                                       17

<PAGE>

Registration Default and one-half of one percent (0.50%) of the aggregate
principal amount of the Debentures from and after the 91st day following such
Registration Default.

     (b) If a Holder has converted some or all of its Securities into Common
Stock, the Holder will be entitled to receive equivalent amounts of Additional
Interest based on the principal amount at maturity of the Securities converted.
A Holder will not be entitled to Additional Interest unless it has provided all
information requested by the Notice and Questionnaire prior to the date of the
Registration Default, if the date of the Registration Default is after the
deadline for the return of the Notice and Questionnaire.

     (c) Notwithstanding the foregoing, in no event will Additional Interest be
payable in connection with a failure to register the Common Stock. For the
avoidance of doubt, if the Company fails to register both the Securities and the
Common Stock, then the Additional Interest shall be payable in connection with
the failure to register the Securities.

     (d) Any amounts to be paid as Additional Interest pursuant to paragraph (a)
of this Section 7 shall be paid in cash semiannually in arrears, with the first
semiannual payment due on the first June 15 or December 15, as applicable,
following the date on which such Additional Interest begin to accrue.

     (e) Except as provided in Section 9(c) hereof, the Additional Interest as
set forth in this Section 7 shall be the exclusive monetary remedy available to
the Holders of Registrable Securities for such Registration Default. In no event
shall the Company be required to pay Additional Interest in excess of the
applicable maximum amount of one-half of one percent (0.50%) set forth above,
regardless of whether one or multiple Registration Defaults exist.

     8. Rule 144A.

     The Company agrees with each Holder, for so long as any Registrable
Securities remain outstanding and during any period in which the Company is not
subject to Section 13 or 15(d) of the Exchange Act, to make available, upon
request of any Holder, to such Holder of Registrable Securities in connection
with any sale thereof and any prospective purchaser of such Registrable
Securities designated by such Holder, the information required by Rule
144A(d)(4) under the Securities Act in order to permit resales of such
Registrable Securities pursuant to Rule 144A.

     9. Miscellaneous.

     (a) Free Writing Prospectuses. Each Holder represents that it has not
prepared or had prepared on its behalf or used or referred to, and agrees that
it will not prepare or have prepared on its behalf or use or refer to, any Free
Writing Prospectus, and has not distributed and will not distribute any written
materials in connection with the offer or sale of the Registrable Securities
without the prior express written consent of the Company and, in connection with
any underwritten offering, the underwriters. Any such Free Writing Prospectus
consented to by the

                                       18

<PAGE>

Company and, if applicable, the underwriters, as the case may be, is hereinafter
referred to as a "Permitted Free Writing Prospectus." The Company represents and
agrees that it has treated and will treat, as the case may be, each Permitted
Free Writing Prospectus as an Issuer Free Writing Prospectus, including in
respect of timely filing with the Commission, legending and recordkeeping.

     (b) Other Registration Rights. The Company may grant registration rights
that would permit any person that is a third party the right to piggy-back on
any Shelf Registration Statement, provided that if the Managing Underwriter of
any underwritten offering conducted pursuant to Section 6 hereof notifies the
Company and the Electing Holders that the total amount of securities which the
Electing Holders and the holders of such piggy-back rights intend to include in
any Shelf Registration Statement is so large as to materially threaten the
success of such offering (including the price at which such securities can be
sold), then the amount, number or kind of securities to be offered for the
account of holders of such piggy-back rights will be reduced to the extent
necessary to reduce the total amount of securities to be included in such
offering to the amount, number and kind recommended by the Managing Underwriter
prior to any reduction in the amount of Registrable Securities to be included in
such Shelf Registration Statement.

     (c) Specific Performance. The parties hereto acknowledge that there would
be no adequate remedy at law if the Company fails to perform any of its
obligations hereunder and that the Purchasers and the Holders from time to time
may be irreparably harmed by any such failure, and accordingly agree that the
Purchasers and such Holders, in addition to any other remedy to which they may
be entitled at law or in equity and without limiting the remedies available to
the Electing Holders under Section 7 hereof, shall, at any time the Securities
