approximately 3:30 p.m., New York City time, on such date from three independent
nationally recognized securities dealers selected by the Company; provided that
if at least three such bids cannot reasonably be obtained by the Trustee, but
two 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, one bid shall be
used; and provided further that if the Trustee cannot reasonably obtain at least
one bid for $5,000,000 Original Principal Amount of Senior Convertible Notes
from a nationally recognized securities dealer or in the Company's reasonable
judgment, the bid quotations are not indicative of the secondary market value of

Payment Date (such day being an "Interest Reset Date"); provided that such rate
will never be less than 0%, from the Original Issue Date, or from the most
recent date to which interest has been paid or provided for, until August 1,
2010. During such period, the Company will pay cash interest semi-annually in
arrears on each Interest Payment Date to Holders of record at the close of
business on each Regular Record Date immediately preceding such Interest Payment
Date. The interest rate in effect for the Senior Convertible Notes on any day
will be (a) if that day is an Interest Reset Date, the interest determined as of
the Determination Date immediately preceding such Interest Reset Date, or (b) if
that day is not an Interest Reset Date, the interest rate determined as of the

accrued through the day immediately preceding the most recent Interest Payment
Date (or the Repurchase Date, Redemption Date, Fundamental Change Purchase Date
or, in certain circumstances, the Conversion Date, as the case may be). Any
payment required to be made on any day that is not a Business Day will be made
on the next succeeding Business Day.

     LIBOR will be determined by the Calculation Agent as of the applicable
determination date in accordance with the following provisions ("Six-Month
LIBOR"):

          (i)        the rate for six-month deposits in US dollars commencing on
     the related Interest Reset Date, that appears on the Moneyline Telerate
     Page 3750 as of 11:00 A.M., London time, on the interest Determination
     Date; or

          (ii)       if no rate appears on the particular interest Determination
     Date on the Moneyline Telerate Page 3750, the rate calculated by the
     Calculation Agent as the arithmetic mean of at least two offered quotations
     obtained by the Calculation Agent after requesting the principal London
     offices of each of four major reference banks in the London interbank
     market to provide the Calculation Agent with its offered quotation for
     deposits in US dollars for the period of six months, commencing on the
     related Interest Reset Date, to prime banks in the London interbank market
     at approximately 11:00 A.M., London time, on that interest Determination
     Date and in a principal amount that is representative for a single
     transaction in US dollars in that market at that time; or

          (iii)      if fewer than two offered quotations referred to in clause
     (ii) are provided as requested, the rate calculated by the Calculation
     Agent as the arithmetic mean of the rates quoted at approximately 11:00
     A.M., New York time, on the particular interest Determination Date by three
     major banks in The City of New York selected by the Calculation Agent for
     loans in US dollars to leading European banks for a period of six months
     and in a principal amount that is representative for a single transaction
     in US dollars in that market at that time; or

          (iv)       if the banks so selected by the Calculation Agent are not
     quoting as mentioned in clause (iii), six-month LIBOR determined on the
     preceding interest Determination Date.

          (v)        "Moneyline Telerate Page 3750" means the display on
     Moneyline Telerate (or any successor service) on such page (or any other
     page as may replace such page on such service) for the purpose of
     displaying the London interbank rates of major banks for US dollars.

     (b) If the Stated Maturity date of the Senior Convertible Notes falls on a
day that is not a LIBOR Business Day, the related payment of principal and
interest will be made on the next LIBOR Business Day as if it were made on the
date such payment was due, and no interest will accrue on the amounts so payable
for the period from and after such Stated Maturity date to the next LIBOR
Business Day. If any Interest Reset Date or Interest Payment Date (other than at
the date of Stated Maturity) would otherwise be a day that is not a LIBOR
Business Day, that Interest Reset Date and Interest Payment Date will be
postponed to the next date that is a LIBOR Business Day, except that if such
LIBOR Business Day is in the next calendar month, such Interest Reset Date and
Interest Payment Date (other than at the date of Stated Maturity) shall be the
immediately preceding LIBOR Business Day.

     (c) Until August 1, 2010, the accreted principal amount (the "Accreted
Principal Amount") of a Senior Convertible Note will be equal to the Original
Principal Amount of $1,000. Beginning August 1, 2010, the Senior Convertible
Note shall not bear interest, except as specified in this paragraph. From such
date, the Original Principal Amount shall commence increasing daily by the
annual rate of Six Month LIBOR plus 0.50% reset on each Interest Reset Date;
provided that such rate will never be less than 0%, to produce the Accreted
Principal Amount. The Accreted Principal Amount will compound semi-annually, not
daily. On Stated Maturity, the Holder of this Senior Convertible Note will
receive the fully Accreted Principal Amount of this Senior Convertible Note on
such date, unless the Senior Convertible Note has been earlier redeemed,
repurchased or converted. Unless cash interest is payable as provided in Section
1.03(a) or (h) hereof, the accrued yield shall be added to the Accreted
Principal Amount per Senior Convertible Note as of the day preceding the most
recent Yield Reset Date. The yield will be calculated using the actual number of
days elapsed between the Yield Reset Dates divided by 360.

     (d) If the Accreted Principal Amount hereof or any portion of such
Accreted Principal Amount is not paid when due (whether upon acceleration
pursuant to Section 502 of the Original Indenture, upon the date set for payment
of the Redemption Price, upon the date set for payment of the Purchase Price or
Fundamental Change Purchase Price or upon the Stated Maturity of the Senior
Convertible Notes) or if installments of cash interest due hereon as provided in
Section 1.03(a) or (h) are not paid when due in accordance with this Section,
then in each such case, the overdue amount shall, to the extent permitted by
law, bear interest at Six Month LIBOR plus 0.50% reset on each Interest Reset
Date (provided that such rate will never be less than 0%) as such rate is in
effect following 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. The accrual of such
interest on overdue amounts shall be in lieu of, and not in addition to, any
subsequent increase in the Accreted Principal Amount.

     (e) The Company will pay contingent interest ("Contingent Interest") to
the Holders of the Senior Convertible Notes in respect of any six-month interest
period from February 1 to July 31 and from August 1 to January 31, commencing on
or after August 1, 2010 for which the average Trading Price of a Senior
Convertible Note for the applicable five Trading Day reference period equals or
exceeds 120% of the sum of the Accreted Principal Amount and accrued interest,
if any, for a Senior Convertible Note as of the day immediately preceding the
first day of the applicable six-month interest period. The "five Trading Day
reference period" means the five Trading Days ending on the third Trading Day
immediately preceding the relevant Interest

                                       10
<Page>

Reset Date. For any six-month interest period in respect of which the Contingent
Interest is payable, the Contingent Interest payable on each $1,000 principal
amount of Notes shall be equal to 0.30% of the average Trading Price of a Senior
Convertible Note for the applicable five Trading Day reference period. No
Contingent Interest shall be payable on Senior Convertible Notes redeemed on
August 1, 2010 (or, if August 1, 2010 is not a Business Day, on the next
following Business Day).

     Upon determination that Holders will be entitled to receive Contingent
Interest in respect of a six-month interest period, the Company shall notify the
Holders. In connection with providing such notice, the Company will issue a
press release containing information regarding the Contingent Interest
determination or publish such information on the Company's then existing website
or through such other public medium as the Company may use at that time.

     (f) Interest, including Contingent Interest, if any, on any Senior
Convertible Note that is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the person in whose name that
Senior Convertible Note is registered at the close of business on the Regular
Record Date for such interest or Contingent Interest, if any, at the office or
agency of the Company maintained for such purpose. Each installment of interest
or Contingent Interest, if any, on any Senior Convertible Note shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States.

     (g) The amount of interest, including Contingent Interest, if any, payable
for any period shall be computed on the basis of the actual number of days
elapsed over a 360-day year. The amount of interest, including Contingent
Interest, if any, payable for any partial period shall be computed on the basis
of a 360-day year of twelve 30-day months and the actual number of days elapsed
in any partial month. In the event that any Interest Payment Date on a Senior
Convertible Note is not a Business Day, then a payment of the interest,
including Contingent Interest, if any, payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay) with the same force and effect as if made
on the date of the payment was originally payable.

     (h) From and after the date (the "Tax Event Date") of the occurrence of a
Tax Event after August 1, 2010, the Company shall have the option to elect by
notice to the Trustee, in lieu of having Accreted Principal Amount increase, to
have interest accrue and be paid in cash at the annual rate equal to Six Month
LIBOR plus 0.50%, reset on each Interest Reset Date; provided that such rate
shall never be less than 0%, on a Restated Principal Amount per $1,000 Original
Principal Amount (the "Restated Principal Amount") equal to the accrued Accreted
Principal Amount through the Tax Event Date or the date the Company exercises
the option provided for in this section, whichever is later (the "Option
Exercise Date"). Such interest shall be payable semi-annually on February 1 and
August 1 of each year to Holders of record at the close of business on January
15 and July 15 immediately preceding such Interest Payment Date. Interest will
accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from the Option Exercise Date. The Trustee shall notify
Holders of Senior Convertible Notes within 15 days after the Option Exercise
Date that the Company has exercised the option provided for in this Section.

                                       11

     SECTION 1.04    DENOMINATIONS. The Senior Convertible Notes shall be issued
in denominations of $1,000 and any integral multiple thereof.

     SECTION 1.05    GLOBAL SECURITIES. (a) The Senior Convertible Notes shall
initially be issued in the form of one or more Global Securities registered in
the name of the Depositary (which initially shall be The Depository Trust
Company) or its nominee. Except under the limited circumstances described below,
Senior Convertible Notes represented by such Global Security or Global
Securities shall not be exchangeable for, and shall not otherwise be issuable
as, Senior Convertible Notes in definitive form ("Definitive Securities"). The
Global Securities described in this Article 1 may not be transferred except by
the Depositary to a nominee of the Depositary or by a nominee of the Depositary
to the Depositary or another nominee of the Depositary or to a successor
Depositary or its nominee.

     (b) A Global Security shall be exchangeable for Senior Convertible Notes
registered in the names of Persons other than the Depositary or its nominee only
if (i) the Depositary notifies the Company that it is unwilling or unable to
continue as a Depositary for such Global Security and no successor Depositary
shall have been appointed by the Company within 90 days of receipt by the
Company of such notification, or if at any time the Depositary ceases to be a
clearing agency registered under the Exchange Act at a time when the Depositary
is required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Company within 90 days after it
becomes aware of such cessation, or (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Senior Convertible Notes registered in such names as the
Depositary shall direct.

     (c) Transfers, exchanges and forms of the Senior Convertible Notes are
further subject to the provisions of Section 1.16.

     SECTION 1.06    REDEMPTION AT THE OPTION OF THE COMPANY. (a) The Senior
Convertible Notes are redeemable as a whole, or from time to time in part, on
any date (a "Redemption Date") at the option of the Company at 100% of the
Accreted Principal Amount of the Senior Convertible Notes, plus any accrued and
unpaid interest and Liquidated Damages to the Redemption Date (the "Redemption
Price"), provided that the Senior Convertible Notes are not redeemable prior to
August 1, 2010. If this Senior Convertible Note has been converted to a
semi-annual cash interest paying note following the occurrence of a Tax Event
and an Option Exercise Date, the Redemption Price will be equal to the Restated
Principal Amount plus accrued and unpaid interest (including Contingent
Interest, if any) and Liquidated Damages, if any, from the date of such
conversion to but not including the Redemption Date; but in no event will this
Senior Convertible Note be redeemable before August 1, 2010.

     (b) The Company shall notify each Holder and the Trustee of the redemption
pursuant to Section 1104 of the Original Indenture.

     (c) If any Senior Convertible Notes selected for partial redemption are
thereafter surrendered for conversion in part before termination of the
conversion right with respect to the portion of the Senior Convertible Notes so
selected, the converted portion of such Senior Convertible Notes shall be deemed
(so far as may be), solely for purposes of determining the

                                       12
<Page>

aggregate principal amount of Senior Convertible Notes to be redeemed by the
Company, to be the portion selected for redemption. Senior Convertible Notes
which have been converted during a selection of Senior Convertible Notes to be
redeemed may be treated by the Trustee as Outstanding for the purpose of such
selection. Nothing in this Section 1.06(c) shall affect the right of any Holder
to convert any Senior Convertible Notes before the termination of the conversion
right with respect thereto. If the Company decides to redeem fewer than all of
the outstanding Senior Convertible Notes then the Trustee will select the Senior
Convertible Notes to be redeemed (in principal amount of $1,000 or integral
multiples thereof) by lot, or on a pro rata basis or by another method the
Trustee considers fair and appropriate.

     (d) In addition to those matters set forth in Section 1104 of the
Indenture, a notice of redemption sent to the Holders of Senior Convertible
Notes shall state:

          (i)        the name of the Paying Agent and Conversion Agent;

          (ii)       the then current Conversion Rate;

          (iii)      that the Senior Convertible Notes called for redemption may
     be converted at any time prior to the close of business on the second
     Business Day immediately preceding the Redemption Date; and

          (iv)       that Holders who wish to convert Senior Convertible Notes
     must comply with the procedures in Section 1.10 hereof and paragraph 7 of
     the reverse of the Senior Convertible Notes.

     (e) The Senior Convertible Notes shall not have a sinking fund.

     SECTION 1.07    PURCHASE AT THE OPTION OF THE HOLDER UPON A FUNDAMENTAL
CHANGE. (a) Each Holder shall have the right, at such Holder's option, to
require the Company to purchase any or all of such Holder's Senior Convertible
Notes for cash in integral multiples of $1,000 Original Principal Amount held by
such Holder by delivery to the Paying Agent (as hereinafter provided) of a
Fundamental Change Purchase Notice no later than 60 Business Days after the
occurrence of a Fundamental Change of the Company (a "Fundamental Change
Purchase Date") for a Fundamental Change purchase price (the "Fundamental Change
Purchase Price") equal to 100% of the Accreted Principal Amount of such Senior
Convertible Notes plus accrued and unpaid interest, including Contingent
Interest, if any, and Liquidated Damages, if any, to but not including the
Fundamental Change Purchase Price Date, which Fundamental Change Purchase Price
shall be paid in cash. No Senior Convertible Notes may be purchased at the
option of the Holders due to a Fundamental Change if there has occurred and is
continuing an Event of Default (other than an Event of Default that is cured by
the payment of the Fundamental Change Purchase Price of such Senior Convertible
Notes).

     (b) EXERCISE OF FUNDAMENTAL CHANGE OPTION. For a Senior Convertible Note
to be so purchased at the option of the Holder pursuant to this Section 1.07,
the Paying Agent must receive, no later than 60 Business Days after the
occurrence of a Fundamental Change:

          (i)        a written notice of purchase (a "Fundamental Change
     Purchase Notice") substantially in the form entitled "Form of Fundamental
     Change Purchase Notice" on the

                                       13
<Page>

     reverse of the Senior Convertible Note duly completed, on or before the
     close of business on the Business Day immediately preceding the Fundamental
     Change Purchase Date, subject to extension to comply with applicable law.
     The Fundamental Change Purchase Notice shall state:

                     (1)  if certificated, the certificate numbers of the Senior
          Convertible Notes which the Holder shall deliver to be purchased;

                     (2)  the portion of the principal amount of the Senior
          Convertible Notes which the Holder shall deliver to be purchased,
          which portion must be $1,000 or an integral multiple thereof; and

                     (3)  that such Senior Convertible Notes shall be purchased
          as of the Fundamental Change Purchase Date pursuant to the terms and
          conditions specified in the Senior Convertible Notes and in the
          Indenture;

          (ii)       delivery or book-entry transfer of such Senior Convertible
     Notes prior to, on or after the Fundamental Change Purchase Date (together
     with all necessary endorsements) at the offices of the Paying Agent, such
     delivery or transfer being a condition to receipt by the Holder of the
     Fundamental Change Purchase Price therefor; provided, however, that such
     Fundamental Change Purchase Price shall be so paid pursuant to this Section
     1.07 only if the Senior Convertible Notes so delivered or transferred to
     the Paying Agent shall conform in all respects to the description thereof
     in the related Fundamental Change Purchase Notice.

     SECTION 1.08    PURCHASE OF SENIOR CONVERTIBLE NOTES AT THE OPTION OF THE
HOLDER. (a) On each of August 1, 2010, August 1, 2013 and August 1, 2018 (each,
a "Repurchase Date"), each Holder shall have the right, at such Holder's option,
to require the Company to purchase any or all of such Holder's Senior
Convertible Notes. The Company shall purchase such Senior Convertible Notes at a
price equal to 100% of the Accreted Principal Amount of the Senior Convertible
Notes to be purchased plus any accrued and unpaid interest, including Contingent
Interest, if any, and Liquidated Damages, if any, on the principal amount to be
purchased to but excluding the Repurchase Date.

     If prior to a Repurchase Date this Senior Convertible Note has been
converted to a semi-annual coupon note following the occurrence of a Tax Event,
the Purchase Price will be equal to the Restated Principal Amount plus accrued
and unpaid cash interest, including Contingent Interest, if any, and Liquidated
Damages, if any, from the date of conversion to the Repurchase Date but not
including the Repurchase Date.

     (b) EXERCISE OF REPURCHASE OPTION.  For a Senior Convertible Note to be so
purchased at the option of the Holder, the Paying Agent must receive:

          (i)        a written notice of purchase (a "Repurchase Notice")
     substantially in the form entitled "Form of Repurchase Notice" on the
     reverse of the Senior Convertible Note duly completed, at any time from the
     opening of business on the date that is 20 Business Days prior to a
     Repurchase Date until the close of business on the third Business Day prior
     to such Repurchase Date. The Repurchase Notice shall state:

                                       14
<Page>

                     (1)  if certificated, the certificate numbers of the Senior
          Convertible Notes which the Holder shall deliver to be purchased;

                     (2)  the portion of the principal amount of the Senior
          Convertible Notes which the Holder shall deliver to be purchased,
          which portion must be $1,000 or an integral multiple thereof; and

                     (3)  that such Senior Convertible Notes shall be purchased
          as of the Repurchase Date pursuant to the terms and conditions
          specified in the Senior Convertible Notes and in the Indenture.

          (ii)       delivery or book-entry transfer of such Senior Convertible
     Notes to the Paying Agent prior to, on or after the Repurchase Date
     (together with all necessary endorsements) at the offices of the Paying
     Agent, such delivery or transfer 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 1.08 only if the Senior
     Convertible Notes so delivered or transferred to the Paying Agent shall
     conform in all respects to the description thereof in the related
     Repurchase Notice.

     SECTION 1.09    FURTHER CONDITIONS AND PROCEDURES FOR PURCHASE UPON A
FUNDAMENTAL CHANGE AND PURCHASE AT THE OPTION OF THE HOLDER.

     (a) NOTICE OF REPURCHASE DATE OR FUNDAMENTAL CHANGE. The Company shall
send notices (each, a "Company Purchase Notice") to the Holders (and to
beneficial owners as required by applicable law) at their addresses shown in the
Senior Convertible Note register maintained by the Security Registrar, and shall
deliver a copy of each such notice to the Trustee and Paying Agent, not less
than 20 Business Days prior to each Repurchase Date, or on or before the 20th
day after the occurrence of the Fundamental Change, as the case may be (each
such date of delivery, a "Company Purchase Notice Date"). Any such notice
delivered to the Trustee and the Paying Agent with respect to a Fundamental
Change shall be accompanied by an Officers' Certificate certifying that a
Fundamental Change has occurred and as to the date of the occurrence thereof, on
which Certificate the Trustee and the Paying Agent may conclusively rely. Each
Company Purchase Notice shall include a Form of Repurchase Notice or Fundamental
Change Purchase Notice to be completed by a Holder and shall state:

     Purchase Price, excluding accrued and unpaid interest, the applicable
     Conversion Rate at the time of such notice (and any applicable adjustments
     to the Conversion Rate) and, to the extent known at the time of such
     notice, the amount of interest that will be payable with respect to the
     Senior Convertible Notes on the applicable Repurchase Date or Fundamental
     Change Purchase Date;

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

          (vi)       that Senior Convertible Notes must be surrendered to the

          (vii)      that Senior Convertible Notes as to which a Repurchase
     Notice or Fundamental Change Purchase Notice has been given by the Holder
     to the Company may be converted only if the applicable Repurchase Notice or
     Fundamental Change Purchase Notice has been withdrawn by the Holder in
     accordance with the terms of this Fifth Supplemental Indenture; provided
     that the Senior Convertible Notes are otherwise convertible in accordance
     with paragraph 7 of the reverse of the Senior Convertible Notes;

          (viii)     that the Purchase Price or Fundamental Change Purchase
     Price for any Senior Convertible Notes as to which a Repurchase Notice or a
     Fundamental Change Purchase Notice, as applicable, has been given and not
     withdrawn shall be paid by the Paying Agent promptly following the later of
     the Repurchase Date or Fundamental Change Purchase Date, as applicable, or
     the time of book-entry transfer or delivery of such Senior Convertible
     Notes;

          (ix)       the procedures the Holder must follow under Sections 1.07
     or 1.08, as applicable, and this Section 1.09;

          (x)        briefly, the conversion rights of the Senior Convertible
     Notes and whether, at the time of such notice, the Convertible Senior Notes
     are eligible for conversion;

          (xi)       that, unless the Company defaults in making payment of such
     Purchase Price or Fundamental Change Purchase Price on Senior Convertible
     Notes covered by any Repurchase Notice or Fundamental Change Purchase
     Notice, as applicable, interest will cease to accrue on and after the
     Repurchase Date or Fundamental Change Purchase Date, as applicable;

will publish a notice containing the information in such Company Purchase Notice
in a newspaper of general circulation in The City of New York or publish such
information on its then existing web site or through such other public medium as
it may use at the time.

     At the Company's request, made at least five Business Days prior to the
date upon which such notice is to be mailed, and at the Company's expense, the
Paying Agent shall give the Company Purchase Notice in the Company's name;
provided, however, that, in all cases, the text of the Company Purchase Notice

     (b) EFFECT OF REPURCHASE NOTICE OR FUNDAMENTAL CHANGE PURCHASE NOTICE.
Upon receipt by the Paying Agent on behalf of the Company from the Holder of the
Fundamental Change Purchase Notice or the Repurchase Notice specified in Section
1.07(b)(i) or Section 1.08(b)(i), as applicable, the Holder of the Senior
Convertible Notes in respect of which such Fundamental Change Purchase Notice or
the Repurchase Notice, as the case may be, was given shall (unless such
Fundamental Change Purchase Notice or the Repurchase Notice is withdrawn as
specified in the following two paragraphs) thereafter be entitled to receive
solely the Fundamental Change Purchase Price or the Purchase Price with respect
to such Senior Convertible Notes. Such Fundamental Change Purchase Price or
Purchase Price shall be paid by the Paying Agent to such Holder promptly
following the later of (x) the Fundamental Change Purchase Date or the
Repurchase Date, as the case may be, with respect to such Senior Convertible
Notes (provided the conditions in Section 1.07(b) or Section 1.08(b), as
applicable, have been satisfied), and (y) the time of delivery or book-entry
transfer of such Senior Convertible Notes to the Paying Agent by the Holder
thereof in the manner required by Section 1.07(b)(ii) or Section 1.08(b)(ii), as
applicable. Senior Convertible Notes in respect of which a Fundamental Change
Purchase Notice or Repurchase Notice, as the case may be, has been given by the
Holder thereof may not be converted for shares of Common Stock on or after the
date of the delivery of such Fundamental Change Purchase Notice or Repurchase
Notice, as the case may be, unless such Fundamental Change Purchase Notice or
Repurchase Notice, as the case may be, has first been validly withdrawn or
deemed to have been validly withdrawn as specified in Section 1.09(c); provided
that the Senior Convertible Notes are otherwise convertible in accordance with
paragraph 7 of the reverse of the Senior Convertible Notes.

     On or before 10:00 a.m. (New York City time) on the Fundamental Change
Purchase Date or the Repurchase Date, as the case may be, the Company shall
deposit with the Paying Agent (or if the Company or an Affiliate of the Company
is acting as the Paying Agent, shall segregate and hold in trust) the Purchase
Price consideration sufficient to pay the aggregate Fundamental Change Purchase
Price or the aggregate Purchase Price, as the case may be, of the Senior
Convertible Notes to be purchased pursuant to Section 1.07 or Section 1.08, as
applicable. Payment by the Paying Agent of such Fundamental Change Purchase
Price or Purchase Price for such Senior Convertible Notes shall be made promptly
following the later of the Fundamental Change Purchase Date or the Repurchase
Date, as the case may be, or the time of book-entry transfer or delivery of such
Senior Convertible Notes. If the Paying Agent holds money sufficient to pay the
Fundamental Change Purchase Price or Purchase Price, as the case may be, of such
Senior Convertible Notes on the Business Day following the Fundamental Change
Purchase Date or the Repurchase Date, as the case may be, then, on and after
such date, such Senior Convertible Notes shall cease to be outstanding and
interest on such Senior Convertible Notes shall cease to accrue, whether or not
book-entry transfer of such Senior Convertible Notes is made or such Senior
Convertible Notes are delivered to the Paying Agent, and all other rights of the
Holder shall terminate (other than the right to receive the Fundamental Change
Purchase Price or the Purchase Price, as the case may be, upon delivery or
transfer of the Senior Convertible Notes). Nothing herein shall preclude the
Company withholding any tax required by law.

     The Company shall require each Paying Agent (other than the Trustee) to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of the
Fundamental Change Purchase Price or the Purchase

                                       17

Price, as the case may be, and shall notify the Trustee of any default by the
Company in making any such payment. If the Company or an Affiliate of the
Company acts as Paying Agent, it shall segregate the money 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 deliver all money held by it pursuant to this Section 1.09 to
the Trustee and to account for any funds disbursed by the Paying Agent. Upon
doing so, the Paying Agent shall have no further liability for the money
delivered to the Trustee.

     All questions as to the validity, eligibility (including time of receipt)
and acceptance of any Senior Convertible Notes for purchase shall be determined
by the Company, whose determination shall be final and binding, absent manifest
error.

     (c) WITHDRAWAL OF A REPURCHASE NOTICE OR FUNDAMENTAL CHANGE PURCHASE
NOTICE. A Repurchase Notice or Fundamental Change 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 at any time prior to 5:00 p.m. New York City time
on the Repurchase Date or the Fundamental Change Purchase Date, as the case may
be, to which it relates specifying:

          (i)        if certificated, the certificate number of the Senior
     Convertible Notes in respect of which such notice of withdrawal is being
     submitted;

          (ii)       the principal amount of the Senior Convertible Notes with
     respect to which such notice of withdrawal is being submitted; and

          (iii)      the principal amount, if any, of such Senior Convertible
     Notes which remains subject to the Repurchase Notice or Fundamental Change
     Purchase Notice, as the case may be, and which has been or shall be
     transferred or delivered for purchase by the Company.

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

     (d) Notwithstanding the requirements of Sections 1.07 or 1.08 and this
Section 1.09, if the Senior Convertible Notes are represented by Global
Securities in book-entry form the appropriate procedures of the Depositary must
be complied with for any purchase upon a Fundamental Change or Repurchase
Option.

     (e) EFFECT OF EVENT OF DEFAULT. There shall be no purchase of any Senior
Convertible Notes pursuant to Section 1.07 or Section 1.08 if an Event of
Default has occurred and is continuing (other than a default that is cured by
the payment of the Purchase Price or Fundamental Change Purchase Price, as the
case may be). The Paying Agent shall promptly return to the respective Holders
thereof any Senior Convertible Notes: (x) with respect to which a Repurchase
Notice or Fundamental Change Purchase Notice, as the case may be, has been
withdrawn in compliance with this Fifth Supplemental Indenture, or (y) held by
it during the continuance of an Event of Default (other than a default that is
cured by the payment of the Purchase Price or Fundamental Change Purchase Price,
as the case may be) in which case, upon such return, the Repurchase Notice or
Fundamental Change Purchase Notice with respect thereto shall be deemed to have
been withdrawn.

                                       18
<Page>

     (f) SENIOR CONVERTIBLE NOTES PURCHASED IN PART. Any Senior Convertible
Notes that are 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 or the Authenticating Agent, if any, shall authenticate and deliver to
the Holder of such Senior Convertible Notes, without service charge, a new
Senior Convertible Note or Senior Convertible Notes, 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 Senior
Convertible Notes so surrendered which is not purchased.

     (g) COVENANT TO COMPLY WITH SECURITIES LAWS UPON PURCHASE OF SENIOR
CONVERTIBLE NOTES. In connection with any offer to purchase Senior Convertible
Notes under Sections 1.07 or 1.08 hereof, the Company shall, to the extent
applicable, (i) comply with Rules 13e-4 and 14e-1 (and any successor provisions
thereto) under the Exchange Act, if applicable, (ii) file the related Schedule
TO (or any successor schedule, form or report) under the Exchange Act, if
applicable and (iii) otherwise comply with all applicable federal and state
securities laws so as to permit the rights and obligations under Sections 1.07,
1.08 or this Section 1.09 to be exercised in the manner specified in Sections
1.07, 1.08 or this Section 1.09; provided, however, that the Company shall not
take any action in violation of any applicable federal or state securities laws.

     (h) REPAYMENT TO THE COMPANY. The Trustee and the Paying Agent shall
return to the Company any cash or property that remains unclaimed as provided in
Section 1003 of the Original Indenture, together with any unclaimed interest,
held by them for the payment of a Purchase Price or Fundamental Change Purchase
Price, as the case may be; provided, however, that to the extent that the
aggregate amount of cash deposited by the Company pursuant to Section 1.09(b),
as applicable, exceeds the aggregate Purchase Price or Fundamental Change
Purchase Price, as the case may be, of the Senior Convertible Notes or portions
thereof which the Company is obligated to purchase as of the Repurchase Date or
Fundamental Change Purchase Date, as the case may be, then promptly on and after
the Business Day following the Repurchase Date or Fundamental Change Purchase
Date, as the case may be, the Trustee or the Paying Agent, as the case may be,
shall return any such excess to the Company together with any excess interest
held by them for payment to Holders.

     (i) In any case where a Repurchase Date or a Fundamental Change Purchase
Date shall not be a Business Day at any Place of Payment, then (notwithstanding
any other provision of the Indenture or the Senior Convertible Notes) payment of
interest and the Purchase Price or the Fundamental Change Purchase Price, as the
case may be, need not be made at such Place of Payment on such date (provided
that all other conditions therefor have been complied with), but may be made on
the next succeeding Business Day at such Place of Payment (provided that such
conditions have been complied with) with the same force and effect as if made on
the Repurchase Date or the Fundamental Change Purchase Date, as the case may be
(and without any interest or payment in respect of any such delay).

     SECTION 1.10    CONVERSION OF SENIOR CONVERTIBLE NOTES.

     (a) RIGHT TO CONVERT. A Holder may convert its Senior Convertible Notes
for Common Stock at any time during the periods specified in paragraph 7 of the
reverse of the Senior Convertible Notes. In lieu of delivery of shares of Common
Stock, the Company shall have the option to satisfy its conversion obligations
in cash as provided herein; provided, however, that the Company shall not have
such option at Stated Maturity or following a notice of redemption pursuant to
Section 1.06 hereof.

     (b) THE CONVERSION RATE. The initial Conversion Rate is 16.2760 shares of
Common Stock issuable upon conversion of $1,000 principal amount of a Senior
Convertible Note (the "Conversion Rate"), subject to adjustment as herein set
forth. A Holder may convert a portion of the principal amount of Senior
Convertible Notes if the portion is $1,000 or an integral multiple thereof. If
the Company elects to satisfy its conversion obligations in cash, the Holder
will receive cash (subject to adjustment as herein set forth) equal to the
product of (x) the product of (A) the Original Principal Amount of the Senior
Convertible Notes to be converted divided by 1,000 and (B) the Conversion Rate,
and (y) the average Closing Sale Price of the Common Stock during the Cash
Settlement Averaging Period.

     (c) CONVERSION PROCEDURES. To convert Senior Convertible Notes, the
requirements set forth in this Section 1.10(c) and in paragraph 7 of the reverse
of the Senior Convertible Notes must be satisfied.

          (i)        To convert the Senior Convertible Notes, a Holder must (1)
     complete and manually sign the irrevocable conversion notice on the back of
     the Senior Convertible Notes (or complete and manually sign a facsimile of
     such notice) and deliver such notice to the Conversion Agent at the office
     maintained by the Conversion Agent for such purpose, (2) with respect to
     Senior Convertible Notes in certificated form, surrender the Senior
     Convertible Notes to the Conversion Agent or with respect to Senior
     Convertible Notes represented by Global Securities, cause the book-entry
     transfer thereof to the Conversion Agent, (3) furnish appropriate
     endorsements and transfer documents if required by the Conversion Agent,
     the Company or the Trustee and (4) pay any transfer or similar tax, if
     required. The date on which the Holder satisfies all such requirements is
     the conversion date (the "Conversion Date"). As soon as practicable, but in
     no event later than the fifth Business Day following the Conversion Date,
     the Company shall deliver to the Holder, through the Conversion Agent, a
     certificate (or credit the book-entry transfer of such shares of Common
     Stock) 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 1.10(d).

          (ii)       Holders of Senior Convertible Notes at the close of
     business on a Regular Record Date will receive payment of interest payable
     on the corresponding Interest Payment Date notwithstanding the conversion
     of such Senior Convertible Notes at any time after the close of business on
     such Regular Record Date. Senior Convertible Notes surrendered for
     conversion by a Holder during the period from the close of business on any
     Regular Record Date to the opening of business on the corresponding
     Interest Payment Date must be accompanied by payment of an amount equal to
     the interest that

                                       20
<Page>

     the Holder is to receive on the Senior Convertible Notes; provided,
     however, that no such payment need be made with respect to Senior
     Convertible Notes in respect of which a Redemption Date or Fundamental
     Change Purchase Date has been set that falls within this period or on such
     Interest Payment Date or to the extent any overdue interest exists at the
     time of such conversion. Except as described above, no payment or
     adjustment will be made for accrued interest on converted Senior
     Convertible Notes. Upon conversion of Senior Convertible Notes, a Holder
     will not receive any cash payment of interest (unless such conversion
     occurs between a Regular Record Date and the Interest Payment Date to which
     it relates) and the Company will not adjust the Conversion Rate to account
     for accrued and unpaid interest.

          (iii)      The Person in whose name the certificate for such shares of
     Common Stock is registered shall be treated as a stockholder of record on
     and after the Conversion Date; provided, however, that no surrender of
     Senior Convertible Notes 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
     Senior Convertible Notes shall have been surrendered for conversion, as if
     the stock transfer books of the Company had not been closed. Upon
     conversion of Senior Convertible Notes, such Person shall no longer be a
     Holder of such Senior Convertible Notes.

          (iv)       No payment or adjustment shall be made for dividends on or
     other distributions with respect to any Common Stock except as provided in
     Section 1.10(g). If a Holder converts more than one Senior Convertible Note
     at the same time, the number of shares of Common Stock issuable upon the
     conversion shall be based on the total principal amount of the Senior
     Convertible Notes converted. Upon surrender of a Senior Convertible Note
     that is converted in part, the Company shall execute, and the Trustee or
     the Authenticating Agent shall authenticate and deliver to the Holder, a
     new Senior Convertible Note in an authorized denomination equal in
     principal amount to the unconverted portion of the Senior Convertible Note
     surrendered. If the last day on which Senior Convertible Notes may be
     converted is not a Business Day in a place where a Conversion Agent is
     located, the Senior Convertible Notes may be surrendered to that Conversion
     Agent on the next succeeding day that is a Business Day. A Holder of Senior
     Convertible Notes is not entitled to any rights of a Holder of Common Stock
     until such Holder has converted its Senior Convertible Notes to Common
     Stock, and only to the extent such Senior Convertible Notes are deemed to
     have been converted into Common Stock pursuant to this Section 1.10.

          (v)        In the event the Company exercises its option pursuant to
     Section 1.03(h) to have, in lieu of having the Accreted Principal Amount
     increase, interest accrue on the Senior Convertible Note following a Tax
     Event, the Holder will be entitled on conversion to receive the same number
     of shares of Common Stock such Holder would have

                                       21
<Page>

     received if the Company had not exercised such option. Increases in the
     Accreted Principal Amount and cash interest (including Contingent Interest,
     if any, and interest payable upon the occurrence of a Tax Event, if any)
     will not be paid on Senior Convertible Notes that are converted, except
     accrued cash interest will be payable upon conversion of Senior Convertible
     Notes made concurrently with or after acceleration of Senior Convertible
     Notes following the Event of Default.

          (vi)       If a Holder of Senior Convertible Notes has already
     delivered a Fundamental Change Purchase Notice or Repurchase Notice with
     respect to a Senior Convertible Note, then the Holder may not surrender
     such Senior Convertible Note for conversion until the Holder has withdrawn
     the applicable Fundamental Change Purchase Notice or Repurchase Notice in
     accordance with the provisions hereof.

          (vii)      On conversion of a Senior Convertible Note, increases in
     the Accreted Principal Amount or cash interest (or interest if the Company
     has exercised its option provided for in Section 1.03(h) hereof)
     attributable to the period from the Original Issue Date (or, if the Company
     has exercised the option provided for in Section 1.03(h) hereof, the later
     of (x) the date of such exercise and (y) the date on which interest was
     last paid) through the Conversion Date 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 (together with the cash
     payment, if any, in lieu of fractional shares) in exchange for the Senior
     Convertible Note being converted pursuant to the terms of the Senior
     Convertible Notes, and the fair market value of such shares of Common Stock
     (together with any such cash payment in lieu of fractional shares) shall be
     treated as issued, to the extent thereof, first in exchange for increases
     in the Accreted Principal Amount or cash interest (or interest, if the
     Company has exercised its option provided for in Section 1.03(h) hereof)
     accrued 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 Original Principal Amount of the
     Senior Convertible Note being converted pursuant to the provisions of the
     Senior Convertible Notes.

          (viii)     If the Company elects to exercise its option to satisfy its
     conversion obligation in cash, it shall notify the Conversion Agent of such
     election during the Cash Settlement Notice Period. Upon such timely notice,
     Holders may retract their conversion notice at any time during the
     Conversion Retraction Period (notwithstanding anything contained herein to
     the contrary). Unless a conversion notice has been retracted pursuant to
     the preceding sentence, settlement in cash through the Conversion Agent
     shall occur on the Business Day immediately following the Cash Settlement
     Averaging Period.

     (d) CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. The Company shall not
issue a fractional share of Common Stock upon conversion of Senior Convertible
Notes. Instead the Company shall 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 1/10,000th of a share by multiplying the Last Reported
Sale Price of a full share of Common Stock on the Trading Day immediately
preceding the Conversion Date by the fractional amount and rounding the product
to the nearest whole cent.

                                       22
<Page>

     (e) TAXES ON CONVERSION. If a Holder converts Senior Convertible Notes, 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 shall be due because the shares are to be issued
in a name other than the Holder's name. Nothing herein shall preclude the
Company's withholding any tax required by law.

     (f) COVENANTS OF THE COMPANY. The Company shall, prior to issuance of any
Senior Convertible Notes hereunder, 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 Senior Convertible Notes.
All shares of Common Stock delivered upon conversion of the Senior Convertible
Notes 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. The Company shall endeavor promptly to
comply with all federal and state securities laws regulating the order and
delivery of shares of Common Stock upon the conversion of Senior Convertible
Notes, if any, and shall cause to have listed or quoted all such shares of
Common Stock on the New York Stock Exchange, or, if not listed thereon, on each
United States national securities exchange or over-the-counter or other domestic
market on which the Common Stock is then listed or quoted.

     (g) ADJUSTMENTS TO CONVERSION RATE. The Conversion Rate shall be adjusted
from time to time by the Company as follows:

          (i)        In case the Company shall pay or make a dividend or other
     distribution on the Common Stock in Common Stock, the Conversion Rate, as
     in effect at the opening of business on the day following the date fixed
     for the determination of stockholders entitled to receive such dividend or
     other distribution, shall be increased by dividing such Conversion Rate by
     a fraction of which the numerator shall be the number of shares of Common
     Stock outstanding at the close of business on the date fixed for such
     determination and the denominator shall be the sum of such number of shares
     and the total number of shares constituting such dividend or other
     distribution, such increase to become effective immediately after the
     opening of business on the day following the date fixed for such
     determination. For the purposes of this Section 1.10(g)(i), the number of
     shares of Common Stock at any time outstanding shall not include shares
     held in treasury by the Company but shall include any shares issuable in
     respect of any scrip certificates issued in lieu of fractions of shares of
     Common Stock. The Company will not pay any dividend or make any
     distribution on shares of Common Stock held in treasury by the Company.

          (ii)       In case the Company shall issue rights, options or warrants
     (other than pursuant to any dividend reinvestment or share purchase plans)
     to all Holders of its Common Stock (not being available on an equivalent
     basis to Holders of the Senior Convertible Notes upon conversion of such
     Senior Convertible Notes) entitling them, for a period expiring within 60
     days after the record date for the determination of

                                       23
<Page>

     stockholders entitled to receive such rights, options or warrants, to
     subscribe for or purchase shares of Common Stock at a price per share less
     than the Current Market Price per share of the Common Stock on the date
     fixed for the determination of stockholders entitled to receive such
     rights, options or warrants (other than pursuant to a dividend reinvestment
     plan or share purchase plan), the Conversion Rate in effect at the opening
     of business on the day following the date fixed for such determination
     shall be increased by dividing such Conversion Rate by a fraction of which
     the numerator shall be the number of shares of Common Stock outstanding at
     the close of business on the date fixed for such determination plus the
     number of shares of Common Stock which the aggregate offering price of the
     total number of shares of Common Stock so offered for subscription or
     purchase would purchase at such Current Market Price and the denominator
     shall be the number of shares of Common Stock outstanding at the close of
     business on the date fixed for such determination plus the number of shares
     of Common Stock so offered for subscription or purchase at such below
     Current Market Price, such increase to become effective immediately after
     the opening of business on the day following the date fixed for such
     determination. For the purposes of this Section 1.10(g)(ii), the number of
     shares of Common Stock at any time outstanding shall not include shares
     held in treasury by the Company but shall include any shares issuable in
     respect of any scrip certificates issued in lieu of fractions of shares of
     Common Stock. The Company shall not issue any such rights, options or
     warrants in respect of shares of Common Stock held in treasury by the
     Company.

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

          (iv)       In case the Company shall, by dividend or otherwise,
     distribute to all Holders of its Common Stock evidences of its
     indebtedness, shares of capital stock, securities, cash or other property
     (but excluding any rights, options or warrants referred to in Section
     1.10(g)(ii) of this Section, any dividend or distribution paid exclusively
     in cash and any dividend or distribution referred to in Section
     1.10(g)(i)), the Conversion Rate shall be adjusted by dividing the
     Conversion Rate in effect immediately prior to the close of business on the
     date fixed for the determination of stockholders entitled to receive such
     distribution by a fraction of which the numerator shall be the Current
     Market Price per share of the Common Stock on the date fixed for such
     determination less the then fair market value (as determined by the Board
     of Directors, whose determination shall be conclusive and described in a
     Board Resolution) on such date of the portion of the evidences of
     indebtedness, shares of capital stock, securities, cash or other property
     so distributed applicable to one share of Common Stock and the denominator
     shall be such Current Market Price per share of the Common Stock, such
     adjustment to become

                                       24
<Page>

     effective immediately prior to the opening of business on the day following
     the date fixed for the determination of stockholders entitled to receive
     such distribution; provided, however, that in the event that the Company
     makes a distribution to all Holders of its Common Stock consisting of
     capital stock of, or similar equity interests in, a subsidiary of the
     Company, the Conversion Rate shall be adjusted by dividing the Conversion
     Rate in effect immediately prior to the close of business on the date fixed
     for the determination of stockholders entitled to receive such distribution
     by a fraction of which the numerator shall be the Spin-off Market Price per
     share of the Common Stock on the date fixed for such determination less the
     Spin-off Market Price per share or similar equity interest of the
     subsidiary of the Company on such date and the denominator shall be the
     Spin-off Market Price per share of the Common Stock, such adjustment to
     become effective 10 trading days after the effective date of such
     distribution of capital stock of, or similar equity interest in, a
     subsidiary or other business unit of the Company. In any case in which this
     Section 1.10(g)(iv) is applicable, Sections 1.10(g)(i) and (ii) shall not
     be applicable.

          (v)        In case the Company shall, (I) by dividend or otherwise,
     distribute to all Holders of its Common Stock cash (excluding (i) any cash
     that is distributed in an event to which Section 1.10(h)(iv) applies or
     (ii) cash that is distributed as part of a distribution referred to in
     Section 1.10(g)(iv)) in an aggregate amount that, combined together with
     (II) the aggregate amount of any other distributions to all Holders of its
     Common Stock made exclusively in cash within the quarterly fiscal period
     containing the date of payment of such distribution and in respect of which
     no adjustment pursuant to this Section 1.10(g)(v) or Section 1.10(g)(vi)
     has been made and (III) the aggregate of any cash plus the fair market
     value of any securities or other property, as of the expiration of the
     applicable tender or exchange offer referred to below (as determined by the
     Board of Directors, whose determination shall be conclusive and described
     in a Board Resolution), of consideration payable in respect of any tender
     or exchange offer (other than consideration payable in respect of any
     odd-lot tender offer) by the Company or any of its subsidiaries for all or
     any portion of the Common Stock concluded within the quarterly fiscal
     period containing the date of payment of the distribution described in
     clause (I) above and in respect of which no adjustment pursuant to this
     Section 1.10(g)(v) or Section 1.10(g)(vi) has been made, exceeds the
     product of $0.13 (appropriately adjusted from time to time for any stock
     dividends on or subdivisions or combinations of Common Stock) multiplied by
     the number of shares of Common Stock outstanding on such date, then, and in
     each such case, immediately after the close of business on such date for
     determination, the Conversion Rate shall be increased so that the same
     shall equal the rate determined by dividing the Conversion Rate in effect
     immediately prior to the close of business on the date fixed for
     determination of the stockholders entitled to receive such distribution by
     a fraction (i) the numerator of which shall be equal to the Current Market
     Price per share of the Common Stock on the date fixed for such
     determination plus $0.13 (appropriately adjusted from time to time for any
     stock dividends on or subdivisions or combination of Common Stock) less an
     amount equal to the quotient of (x) the combined amount distributed or
     payable in the transactions described in clauses (I), (II) and (III) above
     and (y) the number of shares of Common Stock outstanding on such date for
     determination and (ii) the denominator of which shall be equal to the
     Current Market Price per share of the Common Stock on such date for
     determination.

                                       25

          (vi)       In case (I) a tender or exchange offer made by the Company
     or any subsidiary of the Company for all or any portion of the Common Stock
     (other than consideration payable in respect of any odd-lot tender offer)
     shall expire and such tender or exchange offer (as amended upon the
     expiration thereof) shall require the payment to stockholders (based on the
     acceptance (up to any maximum specified in the terms of the tender or
     exchange offer) of Purchased Shares) of an aggregate consideration having a
     fair market value (as determined by the Board of Directors, whose
     determination shall be conclusive and described in a Board Resolution) that
     combined together with (II) the aggregate of the cash plus the fair market
     value (as determined by the Board of Directors, whose determination shall
     be conclusive and described in a Board Resolution), as of the expiration of
     such tender or exchange offer, of consideration payable in respect of any
     other tender or exchange offer (other than consideration payable in respect
     of any odd-lot tender offer) by the Company or any subsidiary of the
     Company for all or any portion of the Common Stock expiring within the
     quarterly fiscal period containing the expiration of such tender or
     exchange offer and in respect of which no adjustment pursuant to Section
     1.10(g)(v) or this Section 1.10(g)(vi) has been made and (III) the
     aggregate amount of any distributions to all Holders of the Company's
     Common Stock made exclusively in cash within the quarterly fiscal period
     containing the expiration of such tender or exchange offer and in respect
     of which no adjustment pursuant to Section 1.10(g)(v) or this Section
     1.10(g)(vi) has been made, exceeds the Current Market Price per share of
     Common Stock on the Trading Day next succeeding the last time (the
     "Expiration Time") tenders could have been made pursuant to such tender or
     exchange offer (as it may be amended), then, and in each such case,
     immediately prior to the opening of business on the day after the date of
     the Expiration Time, the Conversion Rate shall be adjusted so that the same
     shall equal the rate determined by dividing the Conversion Rate immediately
     prior to the close of business as of the Expiration Time by a fraction (i)
     the numerator of which shall be equal to (A) the product of (1) the Current
     Market Price per share of the Common Stock as of the Expiration Time and
     (2) the number of shares of Common Stock outstanding (including any
     tendered shares) as of the Expiration Time less (B) the amount of cash plus
     the fair market value (determined as aforesaid) of the aggregate
     consideration payable to stockholders based on the transactions described
     in clauses (I), (II) and (III) above (assuming in the case of clause (I)
     the acceptance, up to any maximum specified in the terms of the tender or
     exchange offer, of Purchased Shares), and (ii) the denominator of which
     shall be equal to the product of (A) the Current Market Price per share of
     the Common Stock as of the Expiration Time and (B) the number of shares of
     Common Stock outstanding (including any tendered shares) as of the
     Expiration Time less the number of all shares validly tendered 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").

          (vii)      All adjustments to the Conversion Rate, shall be calculated
     to the nearest 1/10,000th of a share of Common Stock (or if there is not a
     nearest 1/10,000th of a share to the next lower 1/10,000th of a share). No
     adjustment in the Conversion Rate shall be required unless such adjustment
     would require an increase or decrease of at least one percent therein;
     provided, however, that any adjustments which by reason of this
     subparagraph are not required to be made because they would have required
     an increase

                                       26
<Page>

     or decrease of less than one percent shall be carried forward and taken
     into account in any subsequent adjustment.

          (viii)     Notwithstanding the foregoing provisions of Section
     1.10(g)(ii) or (iv), no adjustment shall be made thereunder, nor shall an
     adjustment be made to the ability of a Holder of a Note to convert, for any
     distribution described therein if the Holder will otherwise participate in
     the distribution without conversion of such Holder's Senior Convertible
     Notes.

          (ix)       No adjustment pursuant to the Conversion Rate or a Holder's
     ability to convert pursuant to this Section 1.10(g) shall be made in
     connection with the issuance of rights, the distribution of separate
     certificates representing rights or the exercise, redemption, termination
     or invalidation of rights pursuant to any stockholder rights plan
     implemented by the Company which provides that, upon conversion of the
     Senior Convertible Notes, the Holders shall receive, in addition to the
     Common Stock issuable upon such conversion, the rights issued under such
     stockholder rights plan (notwithstanding the occurrence of an event causing
     such rights to separate from the Common Stock at or prior to the time of
     conversion).

     (h) MISCELLANEOUS PROVISIONS RELATING TO CONVERSION.

          (i)        WHEN NO ADJUSTMENT REQUIRED. No adjustment to the
     Conversion Rate need be made:

                     (1)  upon the issuance of any shares of Common Stock
          pursuant to any present or future plan providing for the reinvestment
          of dividends or interest payable on securities of the Company and the
          investment of additional optional amounts in shares of Common Stock
          under any plan;

                     (2)  upon the issuance of any shares of Common Stock or
          options or rights to purchase those shares pursuant to any present or
          future employee, director or consultant benefit plan or program of or
          assumed by the Company or any of its Subsidiaries;

                     (3)  upon the issuance of any shares of Common Stock
          pursuant to any option, warrant, right, or exercisable, exchangeable
          or convertible security not described in (2) above and outstanding as
          of the date the Senior Convertible Notes were first issued;

                     (4)  for a change in the par value of the Common Stock; or

                     (5)  for accrued and unpaid interest.

     To the extent the Senior Convertible Notes become convertible into cash,
     assets or property (other than capital stock of the Company or securities
     to which Section 1.10(h)(iv) applies), no adjustment shall be made
     thereafter as to the cash, assets or property. Interest shall not accrue on
     such cash, assets or property.

                                       27
<Page>

          (ii)       NOTICE OF ADJUSTMENT. Whenever the Conversion Rate is
     adjusted, the Company shall promptly mail to Holders a notice of the
     adjustment. The Company shall file with the Trustee and the Conversion
     Agent such notice. The certificate shall, absent manifest error, 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.

          (iii)      VOLUNTARY INCREASE. The Company may make such increases in
     the Conversion Rate, in addition to those required by Section 1.10(g), as
     the Board of Directors considers to be advisable to avoid or diminish any
     income tax to Holders of Common Stock or rights to purchase Common Stock
     resulting from any dividend or distribution of stock (or rights to acquire
     Common Stock) or from any event treated as such for income tax purposes. To
     the extent permitted by applicable law, the Company may from time to time
     increase the Conversion Rate by any amount for any period of time if the
     period is at least 20 days, the increase is irrevocable during the period
     and the Board of Directors shall have made a determination that such
     increase would be in the best interests of the Company, which determination
     shall be conclusive. Whenever the Conversion Rate is so increased, the
     Company shall mail to Holders and file with the Trustee and the Conversion
     Agent a notice of such increase. Neither the Trustee nor any Conversion
     Agent shall be under any duty or responsibility with respect to any such
     notice except to exhibit the same to any Holder desiring inspection
     thereof. The Company shall mail the notice at least 15 days before the date
     the increased Conversion Rate takes affect. The notice shall state the
     increased Conversion Rate and the period it shall be in effect.

          (iv)       EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER, BINDING
     SHARE EXCHANGE OR SALE. If any of the following events occur, namely (a)
     any reclassification or change of outstanding shares of Common Stock (other
     than a change in par value, or from par value to no par value, or from no
     par value to par value, or as a result of a subdivision or combination),
     (b) any consolidation, merger or binding share exchange of the Company with
     another corporation as a result of which Holders of Common Stock shall be
     entitled to receive stock, securities or other property or assets
     (including cash) with respect to or in exchange for such Common Stock or
     (c) any sale or conveyance of all or substantially all of the assets of the
     Company to any other corporation as a result of which Holders of Common
     Stock shall be entitled to receive stock, securities or other property or
     assets (including cash) with respect to or in exchange for such Common
     Stock, then the Conversion Rate will not be adjusted. If any of the events
     described in the preceding sentence occur, the Company or the successor or
     purchasing corporation, as the case may be, shall execute with the Trustee
     a supplemental indenture or otherwise amend the terms of the Senior
     Convertible Notes, to provide that each Senior Convertible Note shall be
     convertible into the kind and amount of shares of stock, other securities
     or property or assets (including cash) that the Holder of the Senior
     Convertible Note would have received upon such reclassification, change,
     consolidation, merger, binding share exchange, sale or conveyance if such
     Holder had converted such Senior Convertible Note into the number of shares
     of Common Stock issuable upon conversion of such Senior Convertible Note
     immediately prior to such reclassification, change, consolidation, merger,
     combination, binding share exchange, sale or conveyance. Such supplemental

                                       28
<Page>

     indenture or other amendment to the Senior Convertible Notes shall provide
     for adjustments which shall be as nearly equivalent as may be practicable
     to the adjustments provided for in this Section 1.10(h)(iv). The Company
     shall cause notice of the execution of such supplemental indenture or
     amendment of the Senior Convertible Notes to be mailed to each Holder, at
     its address appearing on the Senior Convertible Note register, within 20
     days after execution thereof. Failure to deliver such notice shall not
     affect the legality or validity of such supplemental indenture. The above
     provisions of this Section shall similarly apply to successive
     reclassifications, changes, consolidations, mergers, combinations, binding
     share exchanges, sales and conveyances. If this Section 1.10(h)(iv) applies
     to any event or occurrence, Section 1.10(g) shall not apply.

          (v)        RESPONSIBILITY OF TRUSTEE. The Trustee and any other
     Conversion Agent shall not at any time be under any duty or responsibility
     to any Holder to determine whether any facts exist which may require any
     adjustment of the Conversion Rate and shall be protected in relying upon an
     Officers' Certificate with respect to the same. The Trustee and any other
     Conversion Agent shall not be accountable with respect to the validity or
     value (or the kind or amount) of any shares of Common Stock, or of any
     securities or property, which may at any time be issued or delivered upon
     the conversion of any Senior Convertible Notes and the Trustee and any
     other Conversion Agent make no representations with respect thereto.
     Neither the Trustee nor any Conversion Agent shall be responsible for any
     failure of the Company to issue, transfer or deliver any shares of Common
     Stock or stock certificates or other securities or property or cash upon
     the surrender of any Senior Convertible Notes for the purpose of conversion
     or to comply with any of the duties, responsibilities or covenants of the
     Company contained in this Section 1.10. Without limiting the generality of
     the foregoing, neither the Trustee nor any Conversion Agent shall be under
     any responsibility to determine the correctness of any provisions contained
     in any supplemental indenture entered into pursuant to Section 1.10(h)(iv)
     relating either to the kind or amount of shares of stock or securities or
     other property or assets (including cash) receivable by Holders upon the
     conversion of their Senior Convertible Notes after any event referred to in
     such Section 1.10(h)(iv) or to any adjustment to be made with respect
     thereto, but, subject to the provisions of Article Six of the Indenture,
     may accept as conclusive evidence of the correctness of any such
     provisions, and shall be protected in relying upon, the Officers'
     Certificate (which the Company shall be obligated to file with the Trustee
     prior to the execution of any such supplemental indenture) with respect
     thereto. Neither the Trustee nor the Conversion Agent shall be responsible
     for determining whether any event contemplated by the paragraph 7 of the
     reverse of the Senior Convertible Notes has occurred which makes the Senior
     Convertible Notes eligible for conversion or no longer eligible therefor
     until the Company has delivered to the Trustee and the Conversion Agent an
     Officers' Certificate stating that such event has occurred, on which
     Certificate the Trustee and the Conversion Agent may conclusively rely, and
     the Company agrees to deliver such Officers' Certificate to the Trustee and
     the Conversion Agent immediately after the occurrence of any such event.

     In no event shall the Trustee or the Conversion Agent be liable for any
indirect, special, punitive or consequential loss or damage of any kind
whatsoever, including, but not limited to,

                                       29
<Page>

lost profits, even if the Trustee or the Conversion Agent have been advised of
the likelihood of such loss or damage and regardless of the form of action.

     In no event shall the Trustee or the Conversion Agent be liable for any
failure or delay in the performance of its obligations hereunder because of
circumstances beyond its control, including, but not limited to, acts of God,
flood, war (whether declared or undeclared), terrorism, fire, riot, embargo,
government action, including any laws, ordinances, regulations, governmental
action or the like which delay, restrict or prohibit the providing of the
services contemplated by this Indenture.

          (vi)       SUCCESSIVE ADJUSTMENTS. After an adjustment to the
     Conversion Rate under Section 1.10(g), any subsequent event requiring an
     adjustment under Section 1.10(g) shall cause an adjustment to the
     Conversion Rate as so adjusted.

          (vii)      GENERAL CONSIDERATIONS. Whenever successive adjustments to
     the Conversion Rate are called for pursuant to Sections 1.10(g) or 1.10(h),
     such adjustments shall be made to the Current Market Price as may be
     necessary or appropriate to effectuate the intent of 1.10(g) or 1.10(h) and
     to avoid unjust or inequitable results as determined in good faith by the
     Board of Directors.

     (i) On conversion of a Senior Convertible Note, a Holder shall receive no
payment for that portion of accrued and unpaid interest on the converted Senior
Convertible Note attributable to the period from the most recent Interest
Payment Date (or, if no Interest Payment Date has occurred, from the Original
Issue Date) through the Conversion Date with respect to the converted Senior
Convertible Note.

     SECTION 1.11    ADDITIONAL EVENTS OF DEFAULT; WITHHOLDING NOTICE;
RESCISSION. (a) In addition to those matters set forth in Section 501 of the
Original Indenture, an "Event of Default" with respect to the Senior Convertible
Notes shall also mean any of the following events:

          (i)        default in the Company's obligation to repurchase Senior
Convertible Notes upon the Company's exercise of its repurchase option pursuant
to Section 1.06, upon the occurrence of a Fundamental Change pursuant to Section
1.07 or upon the exercise by a Holder of its option to require the Company to
repurchase such Holder's Senior Convertible Notes pursuant to Section 1.08; or

          (ii)       default in the Company's obligation to convert the Senior
Convertible Notes upon exercise of a Holder's conversion rights pursuant to
Section 1.10 hereof; or

          (iii)      default by the Company in its obligation to provide notice
of a Fundamental Change.

     (b) The Trustee may withhold from the Holders notice of any continuing
default or Event of Default (except a default or Event of Default in the payment
of principal of, interest or Liquidated Damages, if any, on the Senior
Convertible Notes) if it determines in good faith that withholding notice is in
the Holders' interest.

                                       30
<Page>

     (c) The Holders of a majority in aggregate principal amount of the Senior
Convertible Notes then outstanding by notice to the Trustee may rescind any
acceleration of the Senior Convertible Notes and its consequences if all
existing Events of Default (other than the nonpayment of principal of, interest,
Contingent Interest and Liquidated Damages, if any, on the Senior Convertible
Notes that has become due solely by virtue of such acceleration) have been cured
or waived and if the rescission would not conflict with any judgment or decree
of any court of competent jurisdiction. No such rescission will affect any
subsequent default or Event of Default or impair any right consequent thereto.

     SECTION 1.12 AMENDMENT; SUPPLEMENT; AND WAIVER. In addition to those
matters set forth in Section 902 of the Original Indenture, with respect to the
Senior Convertible Notes, no amendment or supplemental indenture shall without
the consent of the Holder of each Senior Convertible Note affected thereby:

     (a) reduce the percentage of the Original Principal Amount of Senior
Convertible Notes whose Holders must consent to an amendment, supplement or
waiver;

     (b) reduce the principal of, or premium on, or change the fixed Stated
Maturity of any Senior Convertible Note or, except as permitted pursuant to
clause (s), (v), (y) or (z) of the immediately following paragraph, alter the
provisions with respect to the redemption or repurchase of the Senior
Convertible Notes;

     (c) reduce the rate of or change the time for payment of interest,
including Contingent Interest, defaulted interest, or Liquidated Damages, on any
Senior Convertible Notes;

     (d) waive a Default or Event of Default in the payment of principal of or
premium, if any, or interest (including Contingent Interest, if any) or
Liquidated Damages, if any, on the Senior Convertible Notes (except a rescission
of acceleration of the Senior Convertible Notes by the Holders of at least a
majority in aggregate Accreted Principal Amount of the Senior Convertible Notes
and a waiver of the payment default that resulted from such acceleration);

     (e) make the principal of, or premium, if any, or interest (including
Contingent Interest, if any) or Liquidated Damages, if any, on, any Senior
Convertible Note payable in money other than as provided for in the Indenture
and in the Senior Convertible Notes;

     (f) make any change in the provisions of the Indenture relating to waivers
of past Defaults or the rights of Holders of Senior Convertible Notes to receive
payments of principal of, premium, if any, or interest (including Contingent
Interest, if any) or Liquidated Damages, if any, on the Senior Convertible
Notes;

     (g) waive a redemption or repurchase payment with respect to any Senior
Convertible Note;

     (h) except as permitted by the Indenture, increase the Conversion Price or
modify the provisions of the Indenture relating to conversion of the Senior
Convertible Notes in a manner adverse to the Holders;

                                       31
<Page>

     (i) make any change to the abilities of Holders of Senior Convertible Notes
to enforce their rights under the Indenture or the foregoing provisions of this
Section 1.12 or this provision;

     (j) reduce the Redemption Price, Purchase Price or Fundamental Change
Purchase Price of the Senior Convertible Notes; or

     (k) make any change that adversely affects the right to convert the Senior
Convertible Notes.

     Notwithstanding the foregoing, without the consent of any Holder, the
Company and the Trustee may amend or supplement the Indenture or the Senior
Convertible Notes to:

     (s) cure any ambiguity, defect or inconsistency or make any other changes
in the provisions of the Indenture which they may deem necessary or desirable,
provided such amendment does not materially and adversely affect the Senior
Convertible Notes;

     (t) provide for uncertificated Senior Convertible Notes in addition to or
in place of certificated Senior Convertible Notes;

     (u) provide for the assumption of the Company's obligations to Holders of
Senior Convertible Notes in the circumstances required under the Indenture;

     (v) provide for exchange rights of Holders of Senior Convertible Notes in
certain events;

     (w) reduce the Conversion Price;

     (x) evidence and provide for the acceptance of the appointment under the
Indenture of a successor Trustee;

     (y) make any change that would provide any additional rights or benefits to
the Holders of Senior Convertible Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder; or

     (z) comply with requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act of 1939.

     In addition, with respect to the Senior Convertible Notes, to the extent
set forth in Section 513 of the Original Indenture, the Holders of at least a
majority in aggregate principal amount of the Outstanding Senior Convertible
Notes may waive an existing default other than: (a) any default by the Company
in any payment of the Redemption Price, Purchase Price or Fundamental Change
Purchase Price with respect to any Senior Convertible Notes, or (b) any default
which constitutes a failure to convert any Senior Convertible Note in accordance
with its terms and the Indenture.

     SECTION 1.13    REGISTER OF SECURITIES; PAYING AGENT; CONVERSION AGENT.
Initially, the Trustee shall act as Paying Agent, Conversion Agent and Security
Registrar with respect to the Senior Convertible Notes with the Place of Payment
for the Senior Convertible Notes initially being the Corporate Trust Office. The
Company may appoint and change any Paying Agent,

                                       32
<Page>

Conversion Agent, Security Registrar or co-registrar or approve a change in the
office through which any Paying Agent acts without notice, other than notice to
the Trustee. The Company or any of its Subsidiaries or any of their Affiliates
may act as Paying Agent, Conversion Agent, Security Registrar or co-registrar.

     SECTION 1.14    CALCULATIONS IN RESPECT OF THE SENIOR CONVERTIBLE NOTES.
The Trustee will act as Calculation Agent and will be responsible for making all
calculations called for under the Senior Convertible Notes other than
calculations of interest. These calculations include, but are not limited to,
determination of the Trading Price, Current Market Price, Closing Sale Price,
interest rate on the Senior Convertible Notes and Conversion Rate of the Senior
Convertible Notes. The Trustee will make these calculations in good faith and,
absent manifest error, these calculations will be final and binding on the
Holders. The Trustee will forward its calculations to any Holder upon the
request of such Holder.

     SECTION 1.15    TAX TREATMENT. The Company hereby agrees, and by purchasing
a beneficial ownership interest in the Senior Convertible Notes each Holder, and
any person (including an entity) that acquires a direct or indirect beneficial
interest in the Senior Convertible Notes, will be deemed to have agreed (i) for
United States Federal income tax purposes to treat the Senior Convertible Notes
as indebtedness of the Company that is subject to Treas. Reg. Sec. 1.1275-4 (the
"Contingent Payment Regulations"), (ii) for all tax purposes to treat the Senior
Convertible Notes as indebtedness of the Company (iii) for purposes of the
Contingent Payment Regulations to treat the fair market value of any Common
Stock beneficially received by a beneficial Holder upon any conversion of the
Senior Convertible Notes (or cash in lieu of Common Stock) as a contingent
payment, and (iv) to be bound by the Company's projected payment schedule with
respect to the Senior Convertible Notes. The provisions of this Indenture shall
be interpreted to further this intention and agreement of the parties. The
comparable yield and the schedule of projected payments are not determined for
any purpose other than for the determination of interest accruals and adjustment
thereof in respect of the Senior Convertible Notes for United States Federal
income tax purposes. The comparable yield and the schedule of projected payments
do not constitute a projection or representation regarding the future stock
price or the amounts payable on the Senior Convertible Notes. For purposes of
the foregoing, the Company's determination of the "comparable yield" is 8.28%
per annum, compounded semiannually. A Holder of Senior Convertible Notes may
obtain the Yield to Maturity, Issue Date, Comparable Yield and Projected Payment
Schedule (which Schedule is attached hereto as Exhibit C) by submitting a
written request to Bausch & Lomb Incorporated, One Bausch & Lomb Place
Rochester, New York 14604, Attention: Chief Financial Officer.

     SECTION 1.16    TRANSFER AND EXCHANGE.

     (a) TRANSFER AND EXCHANGE OF DEFINITIVE SECURITIES. When Definitive
Securities are presented to the Registrar with a request:

          (i)        to register the transfer of such Definitive Securities; or

          (ii)       to exchange such Definitive Securities for an equal
     principal amount of Definitive Securities of other authorized
     denominations, the Registrar shall register the transfer or make the
     exchange as requested if its reasonable requirements for such

                                       33
<Page>

     transaction are met; provided, however, that the Definitive Securities
     surrendered for transfer or exchange:

                     (A)  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

                     (B)  are accompanied by the following additional
          information and documents, as applicable, if such Definitive
          Securities are Transfer Restricted Securities:

                          (x)  if such Definitive Securities are being delivered
                     to the Registrar by a Holder for registration in the name
                     of such Holder, without transfer, a certification from such

     transferred (A) to a QIB in accordance with Rule 144A or (B) outside the

<Page>

          (ii)       written instructions directing the Trustee to make, or to
     direct the securities custodian 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 Definitive Security and cause, or direct the securities custodian to
     cause, in accordance with the standing instructions and procedures existing
     between the Depositary and the securities custodian, the aggregate
     principal amount of securities represented by the Global Security to be
     increased by the aggregate principal amount of the Definitive Security to
     be exchanged and shall 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 Definitive Security so
     canceled. If no Global Securities are then outstanding and the Global
     Security has not been previously exchanged for certificated securities
     pursuant to Section 1.05(b), the Company shall issue and the Trustee shall
     authenticate, upon written order of the Company in the form of an Officers'
     Certificate, a new Global Security in the appropriate principal amount.

     (c) TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.

          (i)        The transfer and exchange of Global Securities or
     beneficial interests therein shall be effected through the Depositary, in
     accordance with this Supplemental Indenture (including applicable
     restrictions on transfer set forth herein, if any) and the procedures of
     the Depositary therefor. A transferor of a beneficial interest in a Global
     Security shall deliver a written order given in accordance with the
     Depositary's procedures containing information regarding the participant
     account of the Depositary to be credited with a beneficial interest in such
     Global Security or another Global Security and such account shall be
     credited in accordance with such order with a beneficial interest in the
     applicable Global Security and the account of the Person making the
     transfer shall be debited by an amount equal to the beneficial interest in
     the Global Security being transferred. Transfers by an owner of a
     beneficial interest in a Rule 144A Global Security to a transferee who
     takes delivery of such interest through a Regulation S Global Security,
     whether before or after the expiration of the Restricted Period, shall be
     made only upon receipt by the Trustee of a certification (in the form set
     forth on the reverse side of the Transfer Restricted Security) from the
     transferor to the effect that such transfer is being made in accordance
     with Regulation S or (if available) Rule 144 under the Securities Act and
     that, if such transfer is being made prior to the expiration of the
     Restricted Period, the interest transferred shall be held immediately
     thereafter through Euroclear or Clearstream.

          (ii)       If the proposed transfer is a transfer of a beneficial
     interest in one Global Security to a beneficial interest in another Global
     Security, the Registrar shall reflect on its books and records the date and
     an increase in the principal amount of the Global Security to which such
     interest is being transferred in an amount equal to the principal amount of
     the interest to be so transferred, and the Registrar shall reflect on its
     books and records the date and a corresponding decrease in the principal
     amount of Global Security from which such interest is being transferred.

     Supplemental Indenture (other than the provisions set forth in Section
     1.05), a Global Security may not be transferred as a whole except by the
     Depositary to a nominee of the Depositary or by a nominee of the Depositary
     to the Depositary or another nominee of the Depositary or by the Depositary
     or any such nominee to a successor Depositary or a nominee of such
     successor Depositary.

          (iv)       In the event that a Global Security is exchanged for
     Definitive Securities pursuant to Section 1.05(b) prior to the
     effectiveness of a Shelf Registration Statement with respect to such
     securities, such securities may be exchanged only in accordance with such
     procedures as are substantially consistent with the provisions of this
     Section 1.16 (including the certification requirements set forth on the
     reverse of the Transfer Restricted Security intended to ensure that such
     transfers comply with Rule 144A, Regulation S or such other applicable
     exemption from registration under the Securities Act, as the case may be)
     and such other procedures as may from time to time be adopted by the
     Company.

     (d) RESTRICTIONS ON TRANSFER OF REGULATION S GLOBAL SECURITY.

          (i)        Prior to the expiration of the Restricted Period, interests
     in a Regulation S Global Security may only be held through Euroclear or
     Clearstream. During the Restricted Period, beneficial ownership interests
     in a Regulation S Global Security may only be sold, pledged or transferred
     through Euroclear or Clearstream in accordance with the Applicable
     Procedures and only (A) to the Company, (B) so long as such security is
     eligible for resale pursuant to Rule 144A, to a person whom the selling
     Holder reasonably believes is a QIB that purchases for its own account or
     for the account of a QIB to whom notice is given that the resale, pledge or
     transfer is being made in reliance on Rule 144A, (C) in an offshore
     transaction in accordance with Regulation S, (D) pursuant to an exemption
     from registration under the Securities Act provided by Rule 144 (if
     applicable) under the Securities Act, or (E) pursuant to an effective
     registration statement under the Securities Act, in each case in accordance
     with any applicable securities laws of any state of the United States.
     Prior to the expiration of the Restricted Period, transfers by an owner of
     a beneficial interest in a Regulation S Global Security to a transferee who
     takes delivery of such interest through a Rule 144A Global Security shall
     be made only in accordance with the Applicable Procedures and upon receipt
     by the Trustee of a written certification from the transferor of the
     beneficial interest in the form provided on the reverse of the Transfer
     Restricted Security to the effect that such transfer is being made to (i) a
     person whom the transferor reasonably believes is a QIB within the meaning
     of Rule 144A in a transaction meeting the requirements of Rule 144A. Such
     written certification shall no longer be required after the expiration of
     the Restricted Period.

          (ii)       Upon the expiration of the Restricted Period, beneficial
     ownership interests in a Regulation S Global Security shall be transferable
     in accordance with applicable law and the other terms of the Indenture.

                           BAUSCH & LOMB INCORPORATED

                     FLOATING RATE CONVERTIBLE NOTE DUE 2023

1.   Interest and Contingent Interest.

     (a)     The Senior Convertible Notes will bear cash interest on the
Original Principal Amount at the annual rate of Six Month LIBOR plus 0.50%,
reset semi-annually on each Interest Payment Date (such day being an "Interest
Reset Date"); provided that such rate will never be less than 0%, from the
Original Issue Date, or from the most recent date to which interest has been
paid or provided for, until August 1, 2010. During such period, the Company will
pay cash interest semi-annually in arrears on each Interest Payment Date to
Holders of record at the close of business on each Regular Record Date
immediately preceding such Interest Payment Date. The interest rate in effect
for the Senior Convertible Notes on any day will be (a) if that day is an
Interest Reset Date, the interest determined as of the Determination Date
immediately preceding such Interest Reset Date or (b) if that day is not an
Interest Reset Date, the interest rate determined as of the Determination Date
immediately preceding the most recent Interest Reset Date. Each payment of cash
interest on the Senior Convertible Notes will include interest (including
Contingent Interest, if any) and Liquidated Damages, if any, accrued through the
day immediately preceding the most recent Interest Payment Date (or the
Repurchase Date, Redemption Date, Fundamental Change Date or, in certain
circumstances, the Conversion Date, as the case may be). Any payment required to
be made on any day that is not a Business Day will be made on the next
succeeding Business Day.

     LIBOR will be determined by the Calculation Agent as of the applicable
determination date in accordance with the following provisions ("Six-Month
LIBOR"):

     (i)     the rate for six-month deposits in US dollars commencing on the
related Interest Reset Date, that appears on the Moneyline Telerate Page 3750 as
of 11:00 A.M., London time, on the interest Determination Date; or

     (ii)    if no rate appears on the particular interest Determination Date on
the Moneyline Telerate Page 3750, the rate calculated by the Calculation Agent
as the arithmetic mean of at least two offered quotations obtained by the
Calculation Agent after requesting the principal London offices of each of four
major reference banks in the London interbank market to provide the Calculation
Agent with its offered quotation for deposits in US dollars for the period of
six months, commencing on the related Interest Reset Date, to prime banks in the
London interbank market at approximately 11:00 A.M., London time, on that
interest Determination Date and in a principal amount that is representative for
a single transaction in US dollars in that market at that time; or

     (iii)   if fewer than two offered quotations referred to in clause (ii) are
provided as requested, the rate calculated by the Calculation Agent as the
arithmetic mean of the rates quoted at approximately 11:00 A.M., New York time,
on the particular interest Determination Date by three major banks in The City
of New York selected by the Calculation Agent for loans in US

                                       A-1
<Page>

dollars to leading European banks for a period of six months and in a principal
amount that is representative for a single transaction in US dollars in that
market at that time; or

     (iv)    if the banks so selected by the Calculation Agent are not quoting
as mentioned in clause (iii), six-month LIBOR determined on the preceding
interest Determination Date.

     "Moneyline Telerate Page 3750" means the display on Moneyline Telerate (or
any successor service) on such page (or any other page as may replace such page
on such service) for the purpose of displaying the London interbank rates of
major banks for US dollars.

     If the Stated Maturity date of the Senior Convertible Notes falls on a day
that is not a LIBOR Business Day, the related payment of principal and interest
will be made on the next LIBOR Business Day as if it were made on the date such
payment was due, and no interest will accrue on the amounts so payable for the
period from and after such Stated Maturity date to the next LIBOR Business Day.
If any Interest Reset Date or Interest Payment Date (other than at the date of
Stated Maturity) would otherwise be a day that is not a LIBOR Business Day, that
Interest Reset Date and Interest Payment Date will be postponed to the next date
that is a LIBOR Business Day, except that if such LIBOR Business Day is in the
next calendar month, such Interest Reset Date and Interest Payment Date (other
than at the date of Stated Maturity) shall be the immediately preceding LIBOR
Business Day.

     (b)     Until August 1, 2010, the Accreted Principal Amount of a Senior
Convertible Note will be equal to the Original Principal Amount of $1,000.
Beginning August 1, 2010, the Senior Convertible Note shall not bear interest,
except as specified in this paragraph of the Indenture. From such date, the
Original Principal Amount shall commence increasing daily by the annual rate of
Six Month LIBOR plus 0.50% reset on each Interest Reset Date; provided that such
rate will never be less than 0%, to produce the Accreted Principal Amount. The
Accreted Principal Amount will compound semi-annually, not daily. On the Stated
Maturity, the Holder of this Senior Convertible Note will receive the fully
Accreted Principal Amount of this Senior Convertible Note on such date, unless
the Senior Convertible Note has been earlier redeemed, repurchased or converted.
Unless cash interest is payable as provided in Section 1.03(a) or (h) hereof,
the accrued yield shall be added to the Accreted Principal Amount per Senior
Convertible Note as of the day preceding the most recent Yield Reset Date. The
yield will be calculated using the actual number of days elapsed between the
Yield Reset Dates divided by 360.

     (c)     If the Accreted Principal Amount hereof or any portion of such
Accreted Principal Amount is not paid when due (whether upon acceleration
pursuant to Section 502 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 Fundamental Change Purchase Price pursuant to paragraph
6 hereof or upon the Stated Maturity of this Senior Convertible Note) or if
installments of cash interest due hereon are not paid when due in accordance
with this paragraph, then in each such case the overdue amount shall, to the
extent permitted by law, bear interest at Six Month LIBOR plus 0.50% reset on
each Interest Reset Date (provided that such rate will never be less than 0%) as
such rate is in effect following the date such overdue amount was due,
compounded quarterly, 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. The accrual of such interest on

                                       A-2
<Page>

overdue amounts shall be in lieu of, and not in addition to, any subsequent
increase in the Accreted Principal Amount.

     (d)     The Company will pay Contingent Interest to the Holders of the
Senior Convertible Notes in respect of any six-month interest period from
February 1 to July 31 and August 1 to January 31, commencing on or after August
1, 2010 for which the average Trading Price of a Senior Convertible Note for the
applicable five Trading Day reference period equals or exceeds 120% of the sum
of the Accreted Principal Amount and accrued interest, if any, for a Senior
Convertible Note as of the day immediately preceding the first day of the
applicable six-month interest period. The "five Trading Day reference period"
means the five Trading Days ending on the third Trading Day immediately
preceding the relevant six-month interest period. For any six-month interest
period in respect of which Contingent Interest is payable, the Contingent
Interest payable on each $1,000 principal amount of Notes shall be equal to
0.30% of the average Trading Price of a Senior Convertible Note for the
applicable five Trading Day reference period. No Contingent Interest shall be
payable on Senior Convertible Notes redeemed pursuant to this paragraph 6 on
August 1, 2010 (or, if August 1, 2010 is not a Business Day, on the next
following Business Day).

     Upon determination that Holders will be entitled to receive Contingent
Interest in respect of a six-month interest period, the Company shall notify the
Holders. In connection with providing such notice, the Company will issue a
press release containing information regarding the Contingent Interest
determination or publish such information on the Company's then existing website
or through such other public medium as the Company may use at that time.

     (e)     Interest, including Contingent Interest, if any, on any Senior
Convertible Note that is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the person in whose name that
Senior Convertible Note is registered at the close of business on the Regular
Record Date for such interest or Contingent Interest, if any, at the office or
agency of the Company maintained for such purpose. Each installment of interest
or Contingent Interest, if any, on any Senior Convertible Note shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States.

     (f)     The amount of interest, including Contingent Interest, if any,
payable for any period shall be computed on the basis of the actual number of
days elapsed over a 360-day year. The amount of interest, including Contingent
Interest, if any, payable for any partial period shall be computed on the basis
of a 360-day year of twelve 30-day months and the actual number of days elapsed
in any partial month. In the event that any Interest Payment Date on a Senior
Convertible Note is not a Business Day, then a payment of the interest,
including Contingent Interest, if any, payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay) with the same force and effect as if made
on the date the payment was originally payable.

2.   Method of Payment.

     Subject to the terms and conditions of the Indenture, the Company will make
payments in respect of Accreted Principal Amount, Redemption Prices, Purchase
Prices, Fundamental Change Purchase Prices and on Stated Maturity to Holders who
surrender Senior Convertible

                                       A-3
<Page>

Notes to a Paying Agent to collect such payments in respect of the Senior
Convertible Notes. In addition, the Company will pay cash interest beginning
November 1, 2003 until August 1, 2010, as more fully described in paragraph 1
hereof. 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.

3.   Paying Agent, Conversion Agent and Registrar.

     Initially, Citibank, N.A. (the "Trustee") will act as Paying Agent,
Conversion Agent and Registrar. The Company may appoint and change any Paying
Agent, Conversion Agent and Registrar or co-registrar without notice, other than
notice to the Trustee except that the Company will 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 the Senior Convertible Notes pursuant to an Indenture
dated as of September 1, 1991, as subsequently supplemented including by the
Fifth Supplemental Indenture thereto dated August 4, 2003 (the "Indenture"),
between the Company and the Trustee. The terms of the Senior Convertible Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Senior Convertible Notes themselves and the Trust Indenture Act
of 1939, as in effect from time to time (the "TIA"). Capitalized terms used
herein and not defined herein have the meanings ascribed thereto in the
Indenture. The Senior Convertible Notes are subject to all such terms, and
Senior Convertible Note Holders are referred to the Indenture and the TIA for a
statement of those terms. In the event of any inconsistency between the terms
hereof and the terms of the Indenture, the terms of the Indenture shall prevail.

     The Senior Convertible Notes are unsecured and unsubordinated obligations
of the Company limited to $140,000,000 aggregate Original Principal Amount (plus
up to $20,000,000 aggregate Original Principal Amount that may be sold by the
Company to the Initial Purchasers pursuant to the option granted to the Initial
Purchasers pursuant to the Purchase Agreement) (subject to the applicable
provisions of the Indenture). 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 Senior Convertible Notes. The Senior
Convertible Notes 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 100%
of the Accreted Principal Amount of the Senior Convertible Notes, plus any
accrued and unpaid interest and Liquidated Damages to the Redemption Date,
provided that the Senior Convertible Notes are not redeemable prior to August 1,
2010.

     If less than all of the outstanding Senior Convertible Notes are to be
redeemed, the Trustee will select the Senior Convertible Notes to be redeemed in
Original Principal Amounts

                                       A-4
<Page>

of $1,000 or integral multiples of $1,000 Original Principal Amount. In this
case, the Trustee may select the Senior Convertible Notes by lot, pro rata or by
any other method the Trustee considers fair and appropriate. If a portion of a
Holder's Senior Convertible Notes is selected for partial redemption and the
Holder converts a portion of the Senior Convertible Notes, the converted portion
will be deemed to be the portion selected for redemption.

     If this Senior Convertible Note has been converted to a semi-annual cash
interest paying note following the occurrence of a Tax Event, the Redemption
Price will be equal to the Restated Principal Amount plus accrued and unpaid
interest (including Contingent Interest, if any) and Liquidated Damages, if any,
from the date of such conversion to but not including the Redemption Date; but
in no event will this Senior Convertible Note be redeemable before August 1,
2010.

     No Contingent Interest shall be payable on Senior Convertible Notes
redeemed pursuant to this paragraph 5 on August 1, 2010 (or if August 1, 2010 is
not a Business Day, on the following Business Day).

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 Senior
Convertible Notes held by such Holder on August 1 of 2010, 2013 and 2018 at a
Purchase Price equal to 100% of the Accreted Principal Amount of such Senior
Convertible Notes on the applicable Repurchase Date plus accrued and unpaid
interest, including Contingent Interest, if any, and Liquidated Damages, if any,
to but not including the Repurchase Date, upon delivery of 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 third Business Day prior to
such Repurchase Date and upon delivery of the Senior Convertible Notes to the
Paying Agent by the Holder as set forth in the Indenture.

     If prior to a Repurchase Date this Senior Convertible Note has been
converted to a semi-annual cash interest paying note following the occurrence of
a Tax Event, the Purchase Price will be equal to the Restated Principal Amount
plus accrued and unpaid cash interest, including Contingent Interest, if any,
and Liquidated Damages, if any, from the date of conversion to the Repurchase
Date but not including the Repurchase Date as provided in the Indenture.

     At the option of the Holder and subject to the terms and conditions of the
Indenture, the Company shall become obligated to purchase in cash all or a
portion of the Senior Convertible Notes in integral multiples of $1,000 Original
Principal Amount held by such Holder no later than 60 Business Days after the
occurrence of a Fundamental Change of the Company for a Fundamental Change
Purchase Price equal to 100% of the Accreted Principal Amount of such Senior
Convertible Notes plus accrued and unpaid interest, including Contingent
Interest, if any, and Liquidated Damages, if any, to but not including the
Fundamental Change Purchase Price Date, which Fundamental Change Purchase Price
shall be paid in cash.

                                       A-5
<Page>

     Holders have the right to withdraw any Repurchase Notice or Fundamental
Change 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.

     Payment of the Purchase Price for a Senior Convertible Note for which a
Repurchase Notice has been delivered and not withdrawn is conditioned upon
book-entry transfer or delivery of such Senior Convertible Note, together with
any necessary endorsements, to the Paying Agent at its office in the Borough of
Manhattan, The City of New York, or any other office or the Paying Agent, at any
time after delivery of the Repurchase Notice.

     If cash sufficient to pay the Purchase Price or Fundamental Change Purchase
Price, as the case may be, of all Senior Convertible Notes or portions thereof
to be purchased as of the Repurchase Date or the Fundamental Change Purchase
Price Date, as the case may be, is deposited with the Paying Agent on the
Business Day immediately following to the Repurchase Date or on the Fundamental
Change Purchase Price Date, as the case may be, such Senior Convertible Notes
(or portions thereof) will cease to be outstanding, the Accreted Principal
Amount shall cease to increase, and cash interest, including Contingent
Interest, if any, and Liquidated Damages, if any, shall cease to accrue on such
Senior Convertible Notes (or portions thereof) on such Repurchase Date or
Fundamental Change Purchase Price 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 Fundamental Change Purchase Price, as the case may be, if any,
upon surrender of such Senior Convertible Notes). This will be the case whether
or not book-entry transfer of the Senior Convertible Note has been made or the
Senior Convertible Note has been delivered to the Paying Agent.

7.   Conversion.

     CONVERSION BASED ON COMMON STOCK PRICE. Subject to the provisions of this
paragraph 7 and notwithstanding the fact that any other condition to conversion
described below has not been satisfied, Holders may convert the Senior
Convertible Notes into Common Stock on a Conversion Date at any time starting
with the first day of any calendar quarter commencing after September 30, 2003
if the Closing 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 such
preceding calendar quarter is greater than the conversion trigger price per
share. The "conversion trigger price" for any calendar quarter shall be 120% of
the accreted Conversion Price per share (as defined below) of Common Stock on
the last Trading Day of such preceding calendar quarter. If the foregoing
condition is satisfied, then the Senior Convertible Notes will be convertible at
any time of the option of the Holder, through their maturity.

     The "ACCRETED CONVERSION PRICE" per share of Common Stock as of any day
equals the quotient of:

     -    the Accreted Principal Amount on that day, divided by

     -    the number of shares of Common Stock issuable upon conversion of
          $1,000 Original Principal Amount of Senior Convertible Notes on that
          day, subject to any adjustments to the Conversion Rate through that
          day.

                                       A-6
<Page>

     Beginning August 1, 2010, the accreted principal amount of a Senior
Convertible Note will be equal to the Original Principal Amount of $ 1,000
increased daily by the annual rate of Six Month LIBOR plus 0.50%, reset on each
Interest Reset Date.

     CONVERSION BASED ON TRADING PRICE OF SENIOR CONVERTIBLE NOTES. Subject to
the provisions of this paragraph 7 and notwithstanding the fact that any other
condition to conversion described below has not been satisfied, Holders may
convert the Senior Convertible Notes, prior to August 1, 2020, into Common Stock
during each of the five Business Day periods after any ten consecutive Trading
Day period in which the Trading Price per $1,000 Original Principal Amount of
the Senior Convertible Notes was less than 97% of the product of (i) the Closing
Sale Price over the same ten day Trading Day period, and (ii) the number of
shares of Common Stock issuable upon conversion of $1,000 Original Principal
Amount of the Senior Convertible Notes. Upon conversion, the Company has the
right to deliver cash or Common Stock.

     The "Trading Price" means, on any date, the average of the secondary market
bid quotations for the Senior Convertible Notes obtained by the Trustee for
$5,000,000 Original Principal Amount of Senior Convertible Notes at
approximately 3:30 p.m., New York City time, on such date from three independent
nationally recognized securities dealers selected by the Company; provided that
if at least three such bids cannot reasonably be obtained by the Trustee, but
two 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, one bid shall be
used; and provided further that if the Trustee cannot reasonably obtain at least
one bid for $5,000,000 Original Principal Amount of Senior Convertible Notes
from a nationally recognized securities dealer or in the Company's reasonable
judgment, the bid quotations are not indicative of the secondary market value of
the Senior Convertible Notes, then the Trading Price per $1,000 Original
Principal Amount of Senior Convertible Notes shall be deemed to be less than 97%
of the product of: (a) the number of shares of Common Stock issuable upon
conversion of $1,000 Original Principal Amount of Senior Convertible Notes, and
(b) the Closing Sale Price on such date.

     The Trustee (or other conversion agent appointed by the Company) shall have
no obligation to determine the Trading Price unless the Company has requested
such a determination; and the Company shall have no obligation to make such
request unless a Holder provides it with reasonable evidence that the Trading
Price per $1,000 Original Principal Amount of Senior Convertible Notes would be
less than 97% of the product of the Closing Sale Price of Common Stock over the
same ten Trading Day period and the number of shares of Common Stock issuable
upon conversion of $1,000 Original Principal Amount of Senior Convertible Notes.
If such evidence is provided, the Company shall instruct the Trustee (or other
conversion agent) to determine the Trading Price of the Senior Convertible Notes
beginning on the next Trading Day and on each successive Trading Day until the
Trading Price per $1,000 Original Principal Amount of Senior Convertible Notes
is greater than 97% of the product of the Closing Sale Price and the number of
shares issuable upon conversion of $ 1,000 Original Principal Amount of the
Senior Convertible Notes.

     CONVERSION UPON REDEMPTION. Subject to the provisions of this paragraph 7
and notwithstanding the fact that any other condition described herein to
conversion has not been satisfied, a Holder may convert into Common Stock a
Senior Convertible Note or portion of a Senior Convertible Note which has been
called for redemption pursuant to paragraph 5 hereof,

                                       A-7
<Page>

provided such Senior Convertible Notes are surrendered for conversion prior to
the close of business on the Business Day immediately preceding the Redemption
Date.

     CONVERSION UPON OCCURRENCE OF CERTAIN CORPORATE TRANSACTIONS. (a) Subject
to the provisions of this paragraph 7 and notwithstanding the fact that any
other condition described herein to conversion has not been satisfied, in the
event the Company is a party to a consolidation, merger or binding share
exchange or a transfer of all or substantially all of the Company's assets
pursuant to which the Common Stock would be converted into cash, securities or
other property as set forth in of the Indenture, the Senior Convertible Notes
may be surrendered for conversion at any time from and after the date which is
15 days prior to the date announced by the Company as the anticipated effective
time until 15 days after the actual effective date of such transaction, and at
the effective time of such transaction the right to convert a Senior Convertible
Note 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
another person which the Holder would have received if the Holder had converted
its Senior Convertible Note into Common Stock immediately prior to the
transaction. If such transaction also constitutes a Fundamental Change, a Holder
will be able to require the Company to purchase all or a portion of such
Holder's Senior Convertible Notes pursuant to Paragraph 6 and of the Indenture.

     (a)     Subject to the provisions of this paragraph 7 and notwithstanding
the fact that any other condition to conversion has not been satisfied, in the
event that the Company declares a dividend or distribution described in Section
1.10(g)(ii) of the Indenture, or a dividend or a distribution described in
Section 1.10(g)(iv) of the Indenture where, the fair market value, per share, of
such dividend or distribution per share of Common Stock, as determined in the
Indenture, exceeds 10% of the Closing Sale Price of the Common Stock on the
Business Day immediately preceding the date of declaration for such dividend or
distribution or a Fundamental Change occurs other than pursuant to a transaction
described in clause (a) hereof, the Senior Convertible Notes 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 Ex-Dividend Date
for such dividend or distribution or which shall be within 20 days after the
occurrence of such Fundamental Change, as the case may be, and Senior
Convertible Notes may be surrendered for conversion at any time thereafter 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 dividend or
distribution will not take place, with respect to a dividend or distribution, or
within 30 days of such Fundamental Change Purchase Notice, in the case of such a
Fundamental Change. No adjustment to the Conversion Rate or the ability of the
Holders to convert this Senior Convertible Note will be made if the Company
provides, as permitted in the Indenture, for Holders to participate in the
transaction without conversion or in other cases specified in the Indenture.

     A Senior Convertible Note in respect of which a Holder has delivered a
Repurchase Notice or Fundamental Change Purchase Notice exercising the option of
such Holder to require the Company to purchase such Senior Convertible Note may
be converted only if such notice of exercise is withdrawn in accordance with the
terms of the Indenture.

     The initial Conversion Rate is 16.2760 shares of Common Stock per $1,000
Original Principal Amount of each Senior Convertible Note, subject to adjustment
for certain events

                                       A-8
<Page>

described in the Indenture. The Company will deliver cash or a check in lieu of
any fractional share of Common Stock. The ability to surrender Senior
Convertible Notes for conversion will expire at the close of business on July
31, 2023.

     In the event the Company exercises its option pursuant to Section 1.03(h)
of the Indenture to have, in lieu of having the Accreted Principal Amount
increase, interest accrue on the Senior Convertible Note following a Tax Event,
the Holder will be entitled on conversion to receive the same number of shares
of Common Stock such Holder would have received if the Company had not exercised
such option.

     Increases in the Accreted Principal Amount and cash interest (including
Contingent Interest, if any, and interest payable upon the occurrence of a Tax
Event, if any) will not be paid on Senior Convertible Notes that are converted,
except accrued cash interest will be payable upon conversion of Senior
Convertible Notes made concurrently with or after acceleration of Senior
Convertible Notes following an Event of Default. Senior Convertible Notes
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 on such Interest Payment Date shall be entitled to receive such
interest payable on such Senior Convertible Notes on the corresponding Interest
Payment Date and, except Senior Convertible Notes to be redeemed within this
period, Senior Convertible Notes surrendered for conversion during such periods
must be accompanied by payment of an amount equal to the interest, including
Contingent Interest, with respect thereto that the registered Holder is to
receive.

     To exercise its conversion right, a Holder must (1) complete and manually
sign the conversion notice (or complete and manually sign a facsimile of such
notice) and deliver such notice to the Conversion Agent, (2) surrender the
Senior Convertible Note to the Conversion Agent, (3) furnish appropriate
endorsements and transfer documents if required by the Conversion Agent, the
Company or the Trustee and (4) pay any transfer or similar taxes, if required.

     A Holder may convert a portion of a Senior Convertible Note if the Original
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 Senior Convertible Note, increases
in the Accreted Principal Amount or cash interest (or interest if the Company
has exercised its option provided for in paragraph 9 hereof) attributable to the
period from the Issue Date (or, if the Company has exercised the option referred
to in paragraph 9 hereof, the later of (x) the date of such exercise and (y) the
date on which interest was last paid) through the Conversion Date 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 (together
with the cash payment, if any, in lieu of fractional shares) in exchange for the
Senior Convertible Note being converted pursuant to the terms hereof, and the
fair market value of such shares of Common Stock (together with any such cash
payment in lieu of fractional shares) shall be treated as issued, to the extent
thereof, first in exchange for increases in the Accreted Principal Amount or
cash interest (or interest, if the Company has exercised its option provided for
in paragraph 9 hereof) accrued through the Conversion Date, and the balance, if
any, of such fair market value of such Common Stock (and any such cash

                                       A-9
<Page>

payment) shall be treated as issued in exchange for the Issue Price of the
Senior Convertible Note being converted pursuant to the provisions hereof.

     The Conversion Rate will be adjusted for dividends or distributions on
Common Stock payable in Common Stock or other Capital Stock of the Company;
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 less than the current market price of the Common Stock at the
time of the announcement of the distribution, distributions to such Holders of
assets or debt securities of the Company or certain rights to purchase
securities of the Company (including cash dividends or distributions) and
payments in respect of a tender offer or exchange offer for Common Stock to the
extent that the cash and value of any other consideration included in the
payment per share of Common Stock exceed the current market price per share of
Common Stock on the Trading Day next succeeding the last date on which tenders
or exchanges may be made pursuant to such tender or exchange offer. However, no
adjustment need be made if Senior Convertible Note Holders may participate in
the transaction or in certain other cases. 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 Senior
Convertible Note into Common Stock may be changed into a right to convert it
into securities, cash or other assets of the Company or another person.

     The Conversion Rate will not be adjusted for increases in the Accreted
Principal Amount or accrued cash interest, Contingent Interest or Liquidated
Damages, if any.

     If a Holder elects to convert all or a portion of a Senior Convertible Note
into shares of Common Stock as set forth above, the Company may choose to
satisfy all or any portion of its conversion obligations in cash as set forth in
the Indenture.

8.   Conversion Arrangement on Call for Redemption.

     Any Senior Convertible Notes 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 Senior Convertible Notes 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 Senior Convertible
Notes from the Holders, to convert them into Common Stock of the Company and to
make payment for such Senior Convertible Notes to the Trustee in trust for such
Holders.

9.   Tax Event.

     From and after the date (the "Tax Event Date") of the occurrence of a Tax
Event after August 1, 2010, the Company shall have the option to elect, by
notice to the Trustee, in lieu of having Accreted Principal Amount increase, to
have interest accrue and be paid in cash at the annual rate equal to Six Month
LIBOR plus 0.50% reset on each Interest Reset Date; provided that such rate
shall never be less than 0%, on a Restated Principal Amount per $1,000 Original
Principal Amount (the "Restated Principal Amount") equal to the accrued Accreted
Principal

                                      A-10
<Page>

Amount through the Tax Event Date or the date the Company exercises the option
provided for in this paragraph 9, whichever is later (the "Option Exercise
Date"). Such interest shall be payable semi-annually on February 1 and August 1
of each year to Holders of record at the close of business on January 15 and
July 15 immediately preceding such interest payment date. Interest will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the Option Exercise Date.

     The Trustee shall notify Holders of Senior Convertible Notes within 15 days
after the Option Exercise Date that the Company has exercised the option
provided for in this paragraph.

10.  Defaulted Interest.

     Except as otherwise specified with respect to the Senior Convertible Notes,
any defaulted interest on any Senior Convertible Note shall forthwith cease to
be payable to the registered Holder thereof on the relevant Regular Record Date
or accrual date, as the case may be, by virtue of having been such Holder, and
such defaulted interest may be paid by the Company as provided for in the
Indenture.

11.  Denominations; Transfer; Exchange.

     The Senior Convertible Notes are in fully registered form, without coupons,
in denominations of $1,000 of Original Principal Amount and integral multiples
of $1,000. A Holder may transfer or exchange Senior Convertible Notes 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 Senior Convertible Notes selected for
redemption (except, in the case of a Senior Convertible Note to be redeemed in
part, the portion of the Senior Convertible Note not to be redeemed) or any
Senior Convertible Notes in respect of which a Repurchase Notice or Designated
Event notice has been given and not withdrawn (except, in the case of a Senior
Convertible Note to be purchased in part, the portion of the Senior Convertible
Note not to be purchased) or any Senior Convertible Notes for a period of 15
days before the mailing of a notice of redemption of Senior Convertible Notes to
be redeemed.

12.  Persons Deemed Owners.

     The registered Holder of this Senior Convertible Note may be treated as the
owner of this Senior Convertible Note 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 Senior Convertible Notes that remains unclaimed for two years,
subject to applicable unclaimed property laws. 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.

Notes may be amended to: (s) cure any ambiguity or correct or supplement any

(a) reduce the percentage of Original Principal Amount of Senior Convertible
Notes whose Holders must consent to an amendment, supplement or waiver; (b)
reduce the principal of, or premium on, or change the Stated Maturity of any
Senior Convertible Note or, except as permitted pursuant to clause (s), (v), (y)
or (z) of the immediately preceding paragraph, alter the provisions with respect

rate of or change the time for payment of interest, including Contingent

majority in aggregate Accreted Principal Amount of the Senior Convertible Notes
and a waiver of the payment default that resulted from such acceleration); (e)

Interest, if any) or Liquidated Damages, if any, on, any Senior Convertible Note
payable in money other than as provided for in the Indenture and in the Senior
Convertible Notes; (f) make any change in the provisions of the Indenture
relating to waivers of past Defaults or the rights of Holders of Senior
Convertible Notes to receive payments of principal of, premium, if any, or

on the Senior Convertible Notes; (g) waive a redemption or repurchase payment
with respect to any Senior Convertible Note; (h) except as permitted by the
Indenture, increase the Conversion Price or modify the provisions of the
Indenture relating to conversion of the Senior Convertible Notes in a manner

                                      A-12

Holders of Senior Convertible Notes to enforce their rights under the Indenture
or the foregoing provisions of this paragraph 14 or this provision; (j) reduce
the Redemption Price, Purchase Price or Fundamental Change Purchase Price of the
Senior Convertible Notes; or (k) make any change that adversely affects the
right to convert the Senior Convertible Notes.

15.  Defaults and Remedies.

     An Event of Default is: (a) default for 30 days or more in payment of any
installment of interest (including contingent interest, if any) or Liquidated
Damages, if any, on the Senior Convertible Notes; (b) default in payment of the
principal of, or premium, if any, on the Senior Convertible Notes, when due at
maturity, upon repurchase, upon acceleration or otherwise; (c) default in the
Company's obligation to repurchase Senior Convertible Notes upon the Company's
exercise of its repurchase option pursuant to Section 1.06 of the Indenture,
upon the occurrence of a Fundamental Change pursuant to Section 1.07 of the
Indenture or upon the exercise by a Holder of its option to require the Company
to repurchase such Holder's Senior Convertible Notes pursuant to Section 1.08 of
the Indenture; (d) default by the Company in its obligation to provide notice of
a Fundamental Change.; (e) default in the Company's obligation to convert the
Senior Convertible Notes upon exercise of a Holder's conversion rights pursuant
to Section 1.10 of the Indenture; (f) default by the Company for 60 days or more
after notice as provided in the Indenture in the observance or performance of
any other covenants in the Indenture; (g) default by the Company under any
mortgage, indenture or instrument under which there may be issued, or by which
there may be secured or evidenced, any indebtedness of the Company for money
borrowed which and shall result in more than $20,000,000 in principal amount of
such indebtedness becoming declared due and payable, and such acceleration shall
not have been rescinded, annulled or discharged within 30 days after notice is
given as specified in the Indenture; or (h) certain events involving bankruptcy,
insolvency or reorganization of the Company or any Material Subsidiary.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate Accreted Principal Amount of the then outstanding
Senior Convertible Notes may declare the unpaid principal of, premium, if any,
and accrued and unpaid interest (including Contingent Interest, if any) and
Liquidated Damages, if any, on all Senior Convertible Notes then outstanding to
be due and payable immediately, except that in the case of an Event of Default
arising from certain events of bankruptcy, insolvency, or reorganization with
respect to the Company or any of its Material Subsidiaries, all outstanding
Senior Convertible Notes become due and payable without further action or
notice. Holders of Senior Convertible Notes may not enforce the Indenture or the
Senior Convertible Notes except as provided in the Indenture. The Trustee may
require an indemnity satisfactory to it before it enforces the Indenture or the
Senior Convertible Notes. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Senior Convertible Notes may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing default (except a default in payment of
principal, premium, if any, or interest (including Contingent Interest, if any)
or Liquidated Damages, if applicable) if it determines that withholding notice
is in their interests. The Company must furnish annual compliance certificates
to the Trustee.

16.  Registration Rights Agreement.

     The Holder of this Senior Convertible Note is entitled to the benefits of a
Registration Rights Agreement, dated August 4, 2003, between the Company and the
Initial Purchasers (the "Registration Rights Agreement"). Pursuant to the
Registration Rights Agreement the Company has agreed for the benefit of the
Holders of the Senior Convertible Notes and the Common Stock issued and issuable
upon conversion of the Senior Convertible Notes, that (i) the Company will, at
its cost, within 90 days after the Issue Date, file a shelf registration
statement (the "Shelf Registration Statement") with the Securities and Exchange
Commission (the "Commission") with respect to resales of the Senior Convertible
Notes and the Common Stock issuable upon conversion thereof, (ii) the Company
will use its reasonable best efforts to cause such Shelf Registration Statement
to be declared effective by the Commission under the Securities Act within 180
days after the Issue Date and (iii) the Company will use its reasonable best
efforts to keep such Shelf Registration Statement continuously effective under
the Securities Act until the earliest of (a) the second anniversary of the Issue
Date or, if later, the second anniversary of the last date on which any Senior
Convertible Notes are issued upon exercise of the Initial Purchasers'
over-allotment option or, if later, the second anniversary of the last date on
which any unregistered Common Stock is issued or issuable upon conversion of the
Senior Convertible Notes, (b) the date on which the Senior Convertible Notes or
the Common Stock issuable upon conversion thereof may be sold by persons who are
not "affiliates" (as defined in Rule 144) of the Company pursuant to paragraph
(k) of Rule 144 (or any successor provision) promulgated by the Commission under
the Securities Act, (c) the date as of which the Senior Convertible Notes or the
Common Stock issuable upon conversion thereof have been transferred pursuant to
Rule 144 under the Securities Act (or any similar provision then in force) and
(d) the date as of which all the Senior Convertible Notes or the Common Stock
issuable upon conversion thereof have been sold pursuant to such Shelf
Registration Statement.

     If the Shelf Registration Statement (i) is not filed with the Commission on
or prior to 90 days, or (ii) has not been declared effective by the Commission
within 180 days, after the Issue Date or (iii) is filed and declared effective
but shall thereafter cease to be effective (without being succeeded immediately
by a replacement shelf registration statement filed and declared effective) or
cease to be usable (including, without limitation, as a result of a Suspension
Period as defined below) for the offer and sale of Transfer Restricted
Securities (as defined below) for a period of time (including any Suspension
Period) which shall exceed 60 days in the aggregate in any 12-month period
during the period beginning on the Issue Date and ending on or prior to the
second anniversary of the Issue Date or, if later, the second anniversary of the
last date on which any Senior Convertible Notes are issued upon exercise of the
Initial Purchasers' overallotment option or, if later, the second anniversary of
the last date on which any unregistered Common Stock is issued or issuable upon
conversion of the Senior Convertible Notes (each such event referred to in
clauses (i), (ii) and (iii) being referred to herein as a "Registration
Default"), the Company will pay liquidated damages ("Liquidated Damages") to
each Holder of Transfer Restricted Securities which has complied with its
obligations under the Registration Rights Agreement. The amount of Liquidated
Damages payable during any period in which a Registration Default shall have
occurred and be continuing is that amount which is equal to one-quarter of one
percent (25 basis points) per annum per $ 1,000 Original Principal Amount of
Senior Convertible Notes constituting Transfer Restricted Securities for the
first 90 days during which a Registration Default has occurred and is continuing
and one-half of one percent (50

                                      A-14
<Page>

basis points) per annum per $1,000 Original Principal Amount of Senior
Convertible Notes constituting Transfer Restricted Securities for any additional
days during which such Registration Default has occurred and is continuing. The
Company will pay all accrued Liquidated Damages by wire transfer of immediately
available funds or by federal funds check on each Damages Payment Date (as
defined in the Registration Rights Agreement), and Liquidated Damages will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
Following the cure of a Registration Default, Liquidated Damages will cease to
accrue with respect to such Registration Default.

     "Transfer Restricted Securities" means each Senior Convertible Note and
each share of Common Stock issued on conversion thereof until the date on which
such Senior Convertible Note or share, as the case may be, (i) has been
transferred pursuant to the Shelf Registration Statement or another registration
statement covering such Senior Convertible Note or share which has been filed
with the Commission pursuant to the Securities Act, in either case after such
registration statement has become and while such registration statement is
effective under the Securities Act, (ii) has been transferred pursuant to Rule
144 under the Securities Act (or any similar provision then in force), or (iii)
may be sold or transferred pursuant to Rule 144(k) under the Securities Act (or
any similar provision then in force).

     Pursuant to the Registration Rights Agreement, the Company may suspend the
use of the prospectus which is a part of the Shelf Registration Statement for a
period not to exceed 30 days in any three-month period or for three periods not
to exceed an aggregate of 90 days in any twelve-month period under certain
circumstances (each, a "Suspension Period"); provided that the existence of a
Suspension Period will not prevent the occurrence of a Registration Default or
otherwise limit the obligation of the Company to pay Liquidated Damages.

     The above description of certain provisions of the Registration Rights
Agreement is qualified by reference to, and is subject in its entirety to, the
more complete description thereof contained in the Registration Rights
Agreement.

17.  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 Senior Convertible Notes 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.

18.  No Recourse Against Others.

     A director, officer, employee, agent, representative, stockholder or equity
Holder, as such, of the Company shall not have any liability for any obligations
of the Company under the Senior Convertible Notes or this Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Senior Convertible Note, each Senior Convertible Note
Holder shall waive and release all such liability. The waiver and release shall
be part of the consideration for the issue of the Senior Convertible Notes.
