          Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for

deliver, the Notes which the Noteholder making the exchange is entitled to receive, bearing
registration numbers not contemporaneously outstanding.

          All Notes presented or surrendered for registration of transfer or for exchange, repurchase or
conversion shall (if so required by the Company, the Trustee, the Security Registrar or any
co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and duly executed, by the Noteholder thereof or his
attorney-in-fact duly authorized in writing.

9

 

          No service charge shall be charged to the Noteholder for any exchange or registration of
transfer of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover
any tax, assessments or other governmental charges that may be imposed in connection therewith.

          None of the Company, the Trustee, the Security Registrar or any co-registrar shall be required
to exchange or register a transfer of (a) any Notes surrendered for conversion or, if a portion of
any Note is surrendered for conversion, such portion thereof surrendered for conversion or (b) any
Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with
Article IX hereof.

          All Notes issued upon any registration of transfer or exchange of Notes in accordance with
this Fifth Supplemental Indenture shall be the valid, binding and legal obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Fifth Supplemental Indenture
as the Notes surrendered upon such registration of transfer or exchange.

               (b) Intentionally Omitted.

               (c) Intentionally Omitted.

               (d) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this instrument or under applicable law
with respect to any transfer of any interest in any Note other than to require delivery of such
certificates and other documentation or evidence as are expressly required by, and to do so if and
when expressly required by, the terms of this instrument, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

               (e) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, all Notes shall be represented by one or more Notes in global form
(each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary.
The transfer and exchange of beneficial interests in a Global Note, which does not involve the
issuance of a definitive Note, shall be effected through the Depositary (but not the Trustee or the
Custodian) in accordance with this Fifth Supplemental Indenture (including the restrictions on
transfer set forth herein) and the procedures of the Depositary therefor.

          Section 2.07 Additional Notes; Repurchases. The Company may, without the consent of the Noteholders and notwithstanding Section 2.01,
issue additional Notes hereunder with the same terms and with the same CUSIP number as the Notes
initially issued hereunder in an unlimited aggregate principal amount, which will form the same
series with the Notes initially issued hereunder, provided that no such additional Notes may be
issued unless fungible with the Notes initially issued hereunder for U.S. federal income tax
purposes. The Company may also from time to time repurchase the Notes in open market purchases by
tender at any price or by private agreement without prior notice to Noteholders.

          Section 2.08 No Sinking Fund. The provisions of Article Twelve of the Base Indenture shall not
be applicable to the Notes. No sinking fund is provided for the Notes.

10

 

          Section 2.09 Ranking. The Notes constitute a senior general obligation of the Company, ranking
equally with other existing and future senior and unsubordinated indebtedness of the Company and
ranking senior in right of payment to any future indebtedness of the Company that is expressly made
subordinate to the Notes by the terms of such indebtedness.

ARTICLE III

REDEMPTION

          Section 3.01 Right to Redeem.

               (a) Notwithstanding any provision of the Base Indenture, as modified by this Fifth
Supplemental Indenture, to the contrary, the Company may redeem the Notes prior to November 15,
2037, in whole, in order to preserve the Company’s status as a real estate investment trust under
the Code.

               (b) Except as provided in Section 3.01(a), the Company may not redeem the Notes prior to
January 15, 2013. On or after January 15, 2013, the Company, at its option, may redeem the Notes
from time to time in whole or in part.

               (c) Any redemption of Notes shall be at a Redemption Price equal to 100% of the principal
amount of the Notes being redeemed, plus accrued and unpaid interest; provided, however, that the
Company may deduct and withhold from such Redemption Price any amount required to be deducted and
withheld under applicable law.

          Section 3.02 Selection of Notes to be Redeemed.

               (a) The provisions of Section 1103 of the Base Indenture shall govern the selection of Notes
to be redeemed by the Trustee provided, however, that if less than all of the Notes are to be
redeemed, the Trustee shall make the selection from the Notes of that series Outstanding and not
previously called for redemption, by lot, or in its discretion, on a pro rata basis..

               (b) If any Note selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Note so selected, the converted portion of such
Note shall be deemed to be part of the portion selected for redemption. Notes which have been
converted subsequent to the Trustee commencing selection of Notes to be redeemed but prior to
redemption of such Notes shall be treated by the Trustee as Outstanding for the purpose of such
selection.

          Section 3.03 Notice of Redemption. The provisions of Section 1104 of the Base Indenture shall
govern notices of redemption of the Notes; provided, however, that in addition to the information
specified in Section 1104 of the Base Indenture, notices of redemption of the Notes shall also
state:

               (a) the then-current Conversion Price;

11

 

               (b) the name and address of the Conversion Agent;

               (c) that Holders who wish to convert Notes must surrender such Notes for conversion no later
than the close of business on the second Business Day immediately preceding the Redemption Date and
must satisfy the other requirements set forth herein; and

               (d) whether the Company will satisfy its Conversion Obligation with respect to any Notes
called for redemption that are surrendered for conversion in cash, Common Shares or both as
provided herein; provided that the Company may not provide notice of a redemption of Notes at the
Company’s option that specifies that the Company will settle conversions of Notes prior to such
redemption in cash and Common Shares unless, at the time of such notice, the Company has available
to it a sufficient number of authorized Common Shares to satisfy its Conversion Obligation in
respect of the Notes to be redeemed.

ARTICLE IV

PARTICULAR COVENANTS OF THE COMPANY

          Section 4.01 Payment of Principal and Interest.

               (a) Sections 307 and 1001 of the Base Indenture shall apply to the Notes; provided, however,
that, with respect to any Noteholder with an aggregate principal amount in excess of $1,000,000, at
the application of such Holder in writing to the Security Registrar not later than the relevant
record date, accrued and unpaid interest on such Holder’s
Notes shall be paid by wire transfer in immediately available funds to such Holder’s account
in the United States supplied by such Holder from time to time to the Trustee and Paying Agent (if
different from Trustee); provided further that payment of accrued and unpaid interest made to the
Depositary shall be paid by wire transfer in immediately available funds in accordance with such
wire transfer instructions and other procedures provided by the Depositary from time to time.

               (b) Except as otherwise provided in this Section 4.01(b), a Holder of any Notes at the close
of business on a Record Date shall be entitled to receive interest on such Notes on the
corresponding Interest Payment Date. A Holder of any Notes as of a Record Date that are converted
after the close of business on such Record Date and prior to the opening of business on the
corresponding Interest Payment Date shall be entitled to receive interest on the principal amount
of such Notes, notwithstanding the conversion of such Notes prior to such Interest Payment Date.
However, a Holder that surrenders any Notes for conversion between the close of business on a
Record Date and the opening of business on the corresponding Interest Payment Date shall be
required to pay the Company an amount equal to the interest payable by the Company with respect to
such Notes on such Interest Payment Date at the time such Holder surrenders such Notes for
conversion, provided, however, that this sentence shall not apply to a Holder that converts Notes:

                    (i) in respect of which the Company has given notice of redemption pursuant to
Section 3.03 on a Redemption Date that is after the relevant Record Date and on or
prior to the relevant Interest Payment Date; or

12

 

                    (ii) to the extent of any overdue interest, if any overdue interest exists at
the time of conversion with respect to such Notes;

                    (iii) in connection with a Fundamental Change in which the Company has
specified a Fundamental Change Repurchase Date that is after a Record Date and on
or prior to the next Interest Payment Date; or

                    (iv) after the Record Date immediately preceding the Maturity Date.

Accordingly, a Holder that converts Notes under any of the circumstances described in clauses (i),
(ii), (iii) or (iv) above will not be required to pay to the Company an amount equal to the
interest payable by the Company with respect to such Notes on the relevant Interest Payment Date.

          Section 4.02 Maintenance of Office or Agency for Conversion Agent. If at any time the
Conversion Agent is not the Trustee or an office or agency designated or appointed by the Trustee,
the Company will give prompt written notice to the Trustee of the location of such Conversion
Agent. If at any time the Company shall fail to maintain an office or agency for the Conversion
Agent, presentations, surrenders, notices and demands related to conversions of Notes may be made
or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of
Manhattan, the City of New York or in the City of Boston.

          Section 4.03 Intentionally Omitted.

          Section 4.04 Intentionally Omitted.

          Section 4.05 Exclusion of Certain Provisions From Base Indenture. Section 1004, Section 1006,

Supplemental Indenture to the Base Indenture), Section 1010 and Section 1012 of the Base Indenture

Note affected thereby:

               (a) make any change that adversely affects the conversion rights of any Notes;

               (b) reduce the Fundamental Change Repurchase Price, Redemption Price or Put Right Repurchase
Price of any Note, or amend or modify in any manner adverse to Noteholders the Company’s obligation
to make such payments or Article III or Article IX of this Fifth Supplemental Indenture, whether
through an amendment or waiver of provisions in the covenants, definitions or otherwise.

          Section 6.03 Effect of Supplemental Indentures. Upon the execution of any supplemental

CONVERSION OF NOTES

          Section 8.01 Conversion Privilege.

               (a) Subject to the conditions described in clauses (b) through (f) below and to Section 8.11
hereof, and upon compliance with the provisions of this Article VIII, a Holder of Notes shall have
the right, at such Holder’s option, to convert all or any portion (if the portion to be converted
is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the
close of business on the scheduled Trading Day immediately preceding October 15, 2012 at a rate
(the “Conversion Rate”) of 12.1957 Common Shares (subject to adjustment by the Company as provided
in Section 8.04) per $1,000 principal amount of Notes (the “Conversion Obligation”) under the
circumstances and during the periods set forth below. On and after October 15, 2012, regardless of
the conditions described in clause (b) through (f) below, upon compliance with the provisions of
this Article VIII and subject to Section 8.11 hereof, a Noteholder shall have the right, at such
holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal
amount or an integral multiple thereof) of such Note at any time prior to the close of business on
the scheduled Trading Day immediately preceding the Maturity Date at a Conversion Rate of 12.1957
Common Shares (subject to adjustment by the Company as provided in Section 8.04) per $1,000
principal amount of Notes.

               (b) (1) A Holder of Notes shall have the right, at such Holder’s option, to convert its Notes
prior to October 15, 2012, during the five Business Day period immediately after any ten
consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000
principal amount of Notes for each day of such Measurement Period was less than 98% of the product
of the Last Reported Sale Price of the Common Shares on such date and the Conversion Rate on such
date, all as determined by the Trustee in the manner described in the immediately succeeding
paragraph. The Trustee shall have no obligation to determine the Trading Price of the Notes unless
requested by the Company to do so in writing, and the Company shall have no obligation to make such
request unless a Noteholder or Noteholders of at least $1,000,000 aggregate principal amount of
Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal
amount of the Notes would be less than 98% of the product of the Last Reported Sale Price at such
time and the then-applicable Conversion Rate, at which time the Company shall select three
independent nationally recognized securities dealers (each, an “Independent Securities Dealer”),
request that the Independent Securities Dealers provide a secondary market quotation for the Notes
and provide such determination to the Company and the Trustee in writing, and the Company shall
instruct

15

 

the Independent Securities Dealers to provide a secondary market quotation for the Notes
beginning on the next Trading Day and on each successive Trading Day until the Trading Price per
$1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Last
Reported Sale Price on such date and the then-applicable Conversion Rate. If the Trading Price
condition set forth above has been met, the Company shall so notify the Noteholders. If at any time
after the Trading Price condition set forth above has been met, the Trading Price per
$1,000 principal amount of Notes is greater than 98% of the product of the Last Reported Sale
Price on such date and the then-applicable Conversion Rate, the Company shall so notify the
Noteholders.

               (2) Any request by the Company to the Trustee for a determination of the Trading Price and
whether the Trading Price condition set forth in the first sentence of the immediately preceding
paragraph has been met shall be accompanied by an Officers’ Certificate setting forth, for each day
of determination (as identified in such Certificate), the name of the Independent Securities
Dealers providing the secondary market bid quotations, a statement certifying that that such
dealers are “Independent Securities Dealers” as required in this Section 8.01, the secondary
market bid quotations obtained from such Independent Securities Dealers (a copy of which will be
attached to such Officers’ Certificate), the Company’s calculation of the Trading Price for such
date. The Trustee shall be entitled to conclusively rely, without independent verification, on the
quotations provided by the Company in making its determinations hereunder. On the basis of such
quotations, the Trustee shall determine the Trading Price of the Notes, and provide such
determination to the Company. Absent manifest error, the Trustee’s determination of the Trading
Price will be binding on the Company. Unless and until a Responsible Officer of the Trustee shall
have received a request from the Company for determination of the Trading Price for the Notes and
the Officers’ Certificate contemplated herein, the Trustee shall have no obligation to make any
determination of the Trading Price of the Notes or whether the Trading Price condition has been
met.

               (c) A Holder of Notes shall have the right, at such Holder’s option, to convert Notes during
any calendar quarter after the quarter ended December 31, 2007, and only during such calendar
quarter, if the Last Reported Sale Price for the Common Shares for at least 20 Trading Days during
the period of 30 consecutive Trading Days ending on the last Trading Day of the previous calendar
quarter exceeds 130% of the Conversion Price (the “Conversion Trigger Price”) on such last Trading
Day, which Conversion Price shall be subject to adjustment in accordance with this Article VIII.
The Conversion Agent shall, on the Company’s behalf, determine at the beginning of each calendar
quarter whether the Notes are convertible as a result of the price of Common Shares as contemplated
in the previous sentence and notify the Company and the Trustee.

               (d) In the event that the Company has delivered a notice of redemption in accordance with
Section 1104 of the Base Indenture and Section 3.03 of this Fifth Supplemental Indenture to the
Holders of Notes, a Holder of Notes may convert Notes at any time prior to the close of business on
the second Business Day immediately preceding the corresponding Redemption Date; provided, however,
that a Holder who has already delivered a Fundamental Change Repurchase Notice with respect to a
Note may not convert such Note until the Holder has withdrawn the Fundamental Change Repurchase
Notice in accordance with the terms of the Note and this Fifth Supplemental Indenture.

16

 

               (e) (1) In the event that the Company elects to:

                         (A) distribute to all or substantially all holders of Common Shares
rights entitling them to purchase, for a period expiring within 60 days,
Common Shares at a price less than
the Last Reported Sale Price of the Common Shares for the Trading
Day immediately preceding the declaration date of such distribution; or

                         (B) distribute to all or substantially all holders of Common
Shares, assets or debt securities of the Company or rights to purchase
the Company’s securities, which distribution has a per share value (as
determined by the Board of Trustees) exceeding 15% of the Last Reported
Sale Price of the Common Shares on the day immediately preceding the
date of declaration of such distribution,

then, in either case, Holders may surrender the Notes for conversion at any time on and after the
date that the Company provides notice to Holders referred to in the next sentence until the earlier
of the close of business on the Business Day immediately preceding the Ex-Dividend Date for such
distribution or the date the Company announces that such distribution will not take place. The
Company shall notify Holders of any distribution referred to in either clause (A) or clause (B)
above and of the resulting conversion right no later than the 35th Business Day prior to the
Ex-Dividend Date for such distribution.

               (2) If the Company is a party to any transaction or event that constitutes a
Fundamental Change, a Holder may surrender Notes for conversion at any time from and after
the 30th scheduled Trading Day prior to the anticipated Effective Date of such transaction
or event until the related Fundamental Change Repurchase Date and, upon such surrender, the
Holder shall be entitled to the increase in the Conversion Rate, if any, specified in
Section 8.01(g). The Company shall give notice to all record Noteholders and the Trustee
and issue a press release of the Fundamental Change no later than 30 scheduled Trading Days
prior to the anticipated effective date of the Fundamental Change.

               (3) If the Company is a party to a consolidation, merger, binding share exchange or
sale or conveyance of all or substantially all of its properties and assets, in each case
pursuant to which the Common Shares would be converted into cash, securities and/or other
property, then the Holders shall have the right to convert Notes at any time beginning
fifteen calendar days prior to the date announced by the Company as the anticipated
effective date of the transaction and until and including the date that is fifteen calendar
days after the date that is the effective date of such transaction; provided such
transaction does not otherwise constitute a Fundamental Change to which the provisions of
Section 8.01(e)(ii) shall apply. The Company shall give notice to all record Noteholders
and the Trustee and issue a press release at least 20 calendar days prior to the
anticipated effective date of such transaction. If the Board of Trustees determines the
anticipated effective date of the transaction, such determination shall be conclusive and
binding on the Holders.

17

 

               (f) The Notes shall be convertible at any time beginning on the first Business Day after any
30 consecutive Trading Day period during which Common Shares are not listed on either a U.S.
national securities exchange.

               (g) (1) If a Noteholder elects to convert Notes in connection with a Fundamental Change that
occurs prior to January 15, 2013, the Conversion Rate applicable to each $1,000 principal amount of
Notes so converted shall be increased by an additional number of Common Shares (the “Additional
Shares”) as described below. Settlement of Notes tendered for conversion to which Additional
Shares shall be added to the Conversion Rate as provided in this subsection shall be settled
pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(g), a conversion
shall be deemed to be “in connection with” a Fundamental Change to the extent that the related
conversion notice is delivered during the time period beginning on the 30th Trading Day prior to
the anticipated Effective Date of such Fundamental Change and ending on the related Fundamental
Change Repurchase Date, inclusive (regardless of whether the provisions of clauses (b), (c), (d),
(e) or (f) of this Section 8.01 shall apply to such conversion). Such conversion notice shall
indicate that the Holder of Notes has elected to convert Notes in connection with a Fundamental
Change; provided, however, that the failure to so indicate shall not in any way affect the
Conversion Obligation or the right of such Holder to receive Additional Shares in connection with
such conversion.

                    (i) The number of Additional Shares by which the Conversion Rate will be
increased shall be determined by reference to the table attached as Schedule A
hereto, based on the date on which the Fundamental Change occurs or becomes
effective (the “Effective Date”), and the Stock Price; provided, that if the Stock
Price is between two Stock Price amounts in the table or the Effective Date is
between two Effective Dates in the table, the number of Additional Shares shall be
determined by a straight-line interpolation between the number of Additional Shares
set forth for the next higher and next lower Stock Price amounts and the two
nearest Effective Dates, as applicable, based on a 365-day year; provided further
that if (1) the Stock Price is greater than $120.00 per Common Share (subject to
adjustment in the same manner as set forth in Section 8.04), no Additional Shares
will be added to the Conversion Rate, and (2) the Stock Price is less than $68.33
per Common Share (subject to adjustment in the same manner as set forth in
Section 8.04), no Additional Shares will be added to the Conversion Rate.
Notwithstanding the foregoing, in no event will the total number of Common Shares
issuable upon conversion exceed 14.6349 per $1,000 principal amount of Notes
(subject to adjustment in the same manner as set forth in clauses (a), (b) and (c)
of Section 8.04).

                    (ii) The Stock Prices set forth in the first row of the table in Schedule A
hereto shall be adjusted as of any date on which the Conversion Rate of the Notes
is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable
immediately prior to such adjustment, multiplied by a fraction, the numerator of
which is the Conversion Rate in effect immediately prior to the adjustment giving
rise to the Stock Price adjustment and the denominator of which is the Conversion
Rate as so adjusted. The number of Additional Shares within the table shall be
adjusted in the same manner as the

18

 

Conversion Rate as set forth in Section 8.04
(other than by operation of an adjustment to the Conversion Rate by adding
Additional Shares).

          Section 8.02 Conversion Procedures.

               (a) (1) The Company shall settle its Conversion Obligations as described in Section
8.02(a)(3), unless, within the applicable time period specified in this Section 8.02(a)(1), the
Company elects to settle its conversion Obligations as described in Section 8.02(a)(2) or Section
8.02(a)(4). The cash and/or Common Shares which the Company is required to deliver in accordance
with this Section 8.02 in settlement of its Conversion Obligations is referred to herein as the
“Settlement Amount.” If the Company desires to settle its Conversion Obligations as described in
Section 8.02(a)(2) or Section 8.02(a)(4), the Company shall notify each converting Noteholder by
notice to the Trustee (for further distribution to Noteholders) of the method the Company will
choose to satisfy its Conversion Obligations no later than the second Trading Day immediately
following the Company’s receipt of a Notice of Conversion from such Holder, and such notice shall
specify the section of this Fifth Supplemental Indenture pursuant to which the Company is electing
to satisfy its conversion obligations; provided, however, that the Company shall have the right to
irrevocably elect, in its sole discretion and without the consent of Noteholders, by notice to the
Trustee (for further distribution to Noteholders), on or prior to October 15, 2012, to settle all
of its future Conversion Obligations entirely in Common Shares as described in Section 8.02(a)(2),
and provided further, that the Company is required to settle all conversions with a Conversion Date
occurring on or after October 15, 2012 in the same manner, and the Company shall notify Noteholders
by notice to the Trustee (for further distribution to Noteholders) of the manner of settlement
(including specifying the applicable section of this Fifth Supplemental Indenture that describes
such manner of settlement) on or before such date. The Company shall treat all Noteholders
converting on the same Trading Day in the same manner; however, the Company shall not have any
obligation to settle its Conversion Obligations arising on different Trading Days in the same
manner, except for conversions with a Conversion Date occurring on or after October 15, 2012, which
shall all be satisfied in the same manner.

               (2) If the Company has elected, within the applicable time periods specified in Section
8.02(a)(1), to settle its Conversion Obligations as described in this Section 8.02(a)(2), the
Company shall have the right to settle its conversion obligations entirely in Common Shares. If
the Company elects to satisfy its Conversion Obligation entirely in Common Shares, the Company
shall deliver a number of Common Shares equal to (i) the aggregate principal amount of Notes to be
converted divided by $1,000, multiplied by (ii) the applicable Conversion Rate (which shall include
any increases to reflect any Additional Shares that such Holder is entitled to receive pursuant to
Section 8.01(g) above). The Company shall deliver such Common Shares as soon as practicable after
it has notified the converting Holder pursuant to Section 8.02(a)(1) above, that it has elected to
satisfy its Conversion Obligation entirely in Common Shares.

               (3) If the Company does not elect, within the applicable time periods specified in Section
8.02(a)(1), to settle its conversion obligations as described in Section 8.02(a)(2) or 8.02(a)(4),
the Company shall settle its Conversion Obligations as described in this Section 8.02(a)(3),
subject to Section 8.02(b) hereof. The Company shall deliver in respect of

19

 

each $1,000 principal amount of Notes being converted a Settlement Amount equal to the sum of
the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the
Observation Period, on the third Trading Day immediately following the last day of the related
Observation Period; provided that the Company will deliver cash in lieu of fractional Common Shares
as set forth pursuant to clause (k) below. The Daily Settlement Amounts shall be determined by the
Company promptly following the last day of the Observation Period.

               (4) If the Company has elected, within the applicable time periods specified in Section
8.02(a)(1), to settle its Conversion Obligations as described in this Section 8.02(a)(4), the
Company shall have the right to settle all or a portion of the amount by which the Daily Conversion
Value exceeds $50 in cash in accordance with this Section 8.02(a)(4). In such case, the Company
shall specify a percentage of the amount by which the Daily Conversion Value exceeds $50 that will
be settled in cash, or the “cash percentage.” The Company will inform converting Holders by notice
to the Trustee (for further distribution to Noteholders) no later than two Trading Days prior to
the first day of the applicable Observation Period if it elects to pay cash upon conversion of the
Notes and shall specify in such notice (the “cash percentage notice”) the applicable cash
percentage. If the Company elects to specify a cash percentage, the amount of cash that the
Company shall deliver in respect of each Trading Day in the applicable Observation Period shall
equal the product of (w) the cash percentage and (x) the amount by which the Daily Conversion Value
exceeds $50 for such Trading Day. The number of Common Shares deliverable in respect of each
Trading Day in the applicable Observation Period shall equal (i) the product of (y) 100% minus the
cash percentage and (z) the amount by which the Daily Conversion Value exceeds $50 for such Trading
Day, divided by (ii) the Daily VWAP of the Common Shares for such Trading Day. If the Company does
not specify a cash percentage, it must settle the entire amount by which the Daily Conversion Value
exceeds $50 with Common Shares pursuant to Section 8.02(a)(3) above; provided, however, that the
Company will deliver cash in lieu of fractional Common Shares as set forth pursuant to clause (k)
below. If the Company specifies a cash percentage, the Company shall satisfy its Conversion
Obligation by delivering, on the third Trading Day immediately following the last day of the
related Observation Period, the amount of cash and the number of Common Shares deliverable pursuant
to this Section 8.02(a)(4).

               (b) Notwithstanding Section 8.02(a), the Company shall satisfy the Conversion Obligation with
respect to each $1,000 principal amount of Notes tendered for conversion to which Additional Shares
shall be added to the Conversion Rate as set forth in Section 8.01(g) pursuant to this clause (b).

                         (A) If the last day of the applicable Observation Period related to
Notes surrendered for conversion is prior to the third Trading Day
preceding the Effective Date of the Fundamental Change, the Company will
satisfy the related Conversion Obligation with respect to each $1,000
principal amount of Notes tendered for conversion as described in
Section 8.01(a) by delivering the amount of cash and Common Shares, if
any (based on the Conversion Rate, but without regard to the number of
Additional Shares to be added to the Conversion Rate pursuant to
Section 8.01(g)) on the third Trading Day immediately following the last
day of the

20

 

applicable Observation Period. In addition, as soon as
practicable
following the Effective Date of the Fundamental Change, the Company
will deliver the increase in such amount of cash and Reference Property
deliverable in lieu of Common Shares, if any, as if the Conversion Rate
had been increased by such number of Additional Shares during the
related Observation Period (and based upon the related Daily VWAP prices
during such Observation Period). If such increased amount of cash and
Common Shares, if any, results in an increase to the amount of cash to
be paid to Holders, the Company will pay such increase in cash, and if
such increased amount results in an increase to the number of Common
Shares, the Company will deliver such increase by delivering Reference
Property based on such increased number of shares.

                         (B) If the last day of the applicable Observation Period related to
Notes surrendered for conversion is on or following the third scheduled
Trading Day preceding the Effective Date of such Fundamental Change, the
Company will satisfy the Conversion Obligation with respect to each
$1,000 principal amount of Notes tendered for conversion as described in
Section 8.01(a) (based on the Conversion Rate as increased by the
Additional Shares pursuant to Section 8.01(g) above) on the later to
occur of (x) the Effective Date of the Fundamental Change and (y) the
third Trading Day immediately following the last day of the applicable
Observation Period.

               (c) Before any Holder of a Note shall be entitled to convert the same as set forth above, such
Holder shall (1) in the case of a Global Note, comply with the procedures of the Depositary in
effect at that time and, if required, pay funds equal to interest payable on the next Interest
Payment Date to which such Holder is not entitled as set forth in Section 4.01(b) and
Section 8.02(i) and, if required, pay all taxes or duties, if any, and (2) in the case of a Note
issued in certificated form, (A) complete and manually sign and deliver an irrevocable written
notice to the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile
thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state in
writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any Common Shares, if
any, to be delivered upon settlement of the Conversion Obligation to be registered, (B) surrender
such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement
and transfer documents), at the office of the Conversion Agent, (C) if required, pay funds equal to
interest payable on the next Interest Payment Date to which such Holder is not entitled as set
forth in Section 4.01(b) and Section 8.02(i), and (D) if required, pay all taxes or duties, if any.
A Note shall be deemed to have been converted immediately prior to the close of business on the
date (the “Conversion Date”) that the Holder has complied with the requirements set forth in this
Section 8.02(c).

          No Notice of Conversion with respect to any Notes may be tendered by a Holder thereof if such
Holder has also tendered a Put Right Repurchase Notice or a Fundamental Change Repurchase Notice
and not validly withdrawn such Put Right Repurchase Notice or

21

 

Fundamental Change Repurchase Notice in accordance with the applicable provisions of
Section 9.01 or 9.02, as the case may be.

     If more than one Note shall be surrendered for conversion at one time by the same Holder, the
Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion
shall be computed on the basis of the aggregate principal amount of the Notes (or specified
portions thereof to the extent permitted thereby) so surrendered.

          (d) Delivery of the amounts owing in satisfaction of the Conversion Obligation shall be made
by the Company in no event later than the date specified in Section 8.02(a), except to the extent
specified in Section 8.02(b). The Company shall make such delivery by paying the cash amount owed
to the Conversion Agent or to the Holder of the Note surrendered for conversion, or such Holder’s
nominee or nominees, and by issuing, or causing to be issued, and delivering to the Conversion
Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry
transfer through the Depositary for the number of full Common Shares to which such Holder shall be
entitled as part of such Conversion Obligation (together with any cash in lieu of fractional
shares).

          (e) In case any Note shall be surrendered for partial conversion, the Company shall execute
and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the
Note so surrendered, without charge to such Holder, a new Note or Notes in authorized denominations
in an aggregate principal amount equal to the unconverted portion of the surrendered Notes.

          (f) If a Holder submits a Note for conversion, the Company shall pay all stamp and other
duties, if any, which may be imposed by the United States or any political subdivision thereof or
taxing authority thereof or therein with respect to the issuance of Common Shares, if any, upon the
conversion. However, the Holder shall pay any such tax that is due because the Holder requests any
Common 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 Shares being issued in a name other than the
Holder’s name until the Trustee receives a sum sufficient to pay any tax which will be due because
the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude
any tax withholding required by law or regulations.

          (g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any
shares issued upon the conversion of any Note as provided in this Article.

          (h) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Global Note as to the reduction in the
principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee.

          (i) Upon conversion, a Noteholder will not receive any separate cash payment for accrued and
unpaid interest, except as set forth below. The Company’s settlement of its Conversion Obligation
as described above shall be deemed to satisfy its obligation to pay

22

 

the principal amount of the
Note and accrued and unpaid interest to, but not including, the Conversion Date. As a result,
accrued and unpaid interest to, but not including, the Conversion Date shall be deemed to be paid
in full rather than cancelled, extinguished or forfeited.
Notwithstanding the preceding sentence, if Notes are converted after the close of business on
a Record Date, Holders of such Notes as of the close of business on the Record Date will receive
the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the
conversion. Notes surrendered for conversion 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 payable on the Notes so converted;
provided, however, that no such payment need be made (1) if the Company has called the Notes for
redemption or (2) to the extent of any overdue interest existing at the time of conversion with
respect to such Note, (3) to Notes surrendered for conversion in connection with a Fundamental
Change in which the Company has specified a Fundamental Change Repurchase Date that is after a
Record Date and on or prior to the next Interest Payment Date, or (4) to Notes surrendered for
conversion after the Record Date immediately preceding the Maturity Date. Except as described
above, no payment or adjustment will be made for accrued interest on converted Notes.

          (j) The Person in whose name the certificate for any Common Shares issued upon conversion is
registered shall be treated as a shareholder of record on and after the Conversion Date; provided,
however, that no surrender of 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 Common
Shares upon such conversion as the record holder or holders of such Common Shares on such date, but
such surrender shall be effective to constitute the Person or Persons entitled to receive such
Common Shares 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 Notes shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of
Notes, such Person shall no longer be a Noteholder.

          (k) No fractional Common Shares shall be issued upon conversion of any Note or Notes. If more
than one Note shall be surrendered for conversion at one time by the same Holder, the number of
full shares that shall be issued upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof) so surrendered. Instead of
any fractional Common Share that would otherwise be issued upon conversion of any Note or Notes (or
specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction
(calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the
Last Reported Sale Price of the Common Shares on the last day of the applicable Observation Period.

          (l) Reserved.

     Section 8.03 Reserved.

     Section 8.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time
to time by the Company as follows:

23

 

          (a) In case the Company shall issue Common Shares as a dividend or distribution to holders of
the outstanding Common Stock, or shall effect a subdivision into a
greater number of Common Shares or combination into a lesser number of Common Shares, the
Conversion Rate shall be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such event;
	 
	 	 	 	 
	CR¢

	 	=
	 	the Conversion Rate in effect immediately after such event;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of Common Shares outstanding immediately prior to such event; and
	 
	 	 	 	 
	OS¢

	 	=
	 	the number of Common Shares outstanding immediately after such event.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the
Business Day following the record date fixed for such determination. If any dividend or
distribution of the type described in this Section 8.04(a) is declared but not so paid or made, or
the outstanding Common Shares are not subdivided or combined, as the case may be, the Conversion
Rate shall be immediately readjusted, effective as of the date the Board of Trustees determines not
to pay such dividend or distribution, or subdivide or combine the outstanding Common Shares, as the
case may be, to the Conversion Rate that would then be in effect if such dividend, distribution,
subdivision or combination had not been declared.

          (b) In case the Company shall issue to all or substantially all holders of its outstanding
Common Shares any rights, warrants or convertible securities entitling them (for a period expiring
within sixty (60) calendar days after the issuance thereof) to subscribe for or purchase Common
Shares at a price per share less than the Last Reported Sale Price of the Common Shares on the
Business Day immediately preceding the date of announcement of such issuance, the Conversion Rate
shall be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such event;
	 
	 	 	 	 
	CR¢

	 	=
	 	the Conversion Rate in effect immediately after such event;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of Common Shares outstanding immediately prior to such event;

24

 

	 	 	 	 	 
	X

	 	=
	 	the total number of Common Shares issuable pursuant to such rights, warrants or convertible securities; and
	 
	 	 	 	 
	Y

	 	=
	 	the number of Common Shares equal to the aggregate price
payable to exercise such rights, warrants or convertible securities divided by
the average of the Last Reported Sale Prices per Common Share over the ten
consecutive Trading Day period ending on the Business Day immediately preceding
the record date (or, if later, the Ex-Date relating to such distribution) for
the issuance of such rights, warrants or convertible securities.

Such adjustment shall be successively made whenever any such rights, warrants or convertible
securities are issued and shall become effective immediately after 9:00 a.m., New York City time,
on the Business Day following the date fixed for such determination. If such rights, warrants or
convertible securities are not so exercised prior to their expiration, the Conversion Rate shall
again be adjusted to be the Conversion Rate that would then be in effect if such record date for
such distribution had not been fixed.

     In determining whether any rights, warrants or convertible securities entitle the holder
thereof to subscribe for or purchase Common Shares at a price per share less than the Last Reported
Sale Price of the Common Shares on the Business Day immediately preceding the date of announcement
of such issuance, and in determining the aggregate offering price of such Common Shares, there
shall be taken into account any consideration received by the Company for such rights, warrants or
convertible securities and any amount payable on exercise or conversion thereof, the value of such
consideration, if other than cash, to be determined by the Board of Trustees.

          (c) In case the Company shall distribute to all or substantially all holders of its Common
Shares shares of beneficial interest, evidences of its indebtedness or other assets or property of
the Company (including securities, but excluding dividends and distributions covered by
Section 8.04(a), Section 8.04(b) or Section 8.04(d) and distributions described below in this
paragraph (c) with respect to Spin-Offs) (any of such shares of beneficial interest, indebtedness,
or other asset or property hereinafter in this Section 8.04(c) called the “Distributed Property”),
then, in each such case the Conversion Rate shall be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such distribution;
	 
	 	 	 	 
	CR¢

	 	=
	 	the Conversion Rate in effect immediately after such distribution;

25

 

	 	 	 	 	 	 	 
	 

	 	SP0
	 	=
	 	the average of the Last Reported Sale Prices of the Common Shares
over the ten consecutive Trading Day period ending on the Business Day
immediately preceding the record date for such distribution (or, if earlier,
the Ex-Date relating to such distribution); and
	 
	 	 	 	 	 	 
	 

	 	FMV
	 	=
	 	the fair market value (as determined by the Board of
Trustees) of the Distributed Property distributed with respect to each
outstanding share of Common Shares on the record date for such distribution
(or, if earlier, the Ex-Date relating to such distribution).

Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the
Business Day following the date fixed for the determination of shareholders entitled to receive
such distribution; provided that if the then fair market value (as so determined) of the portion of
the Distributed Property so distributed applicable to one Common Share is equal to or greater than
SP0 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be
made so that each Noteholder shall have the right to receive, for each $1,000 principal amount of
Notes upon conversion, the amount of Distributed Property such Holder would have received had such
Holder owned a number of Common Shares equal to the Conversion Rate on the record date. If such
dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. If the Board of Trustees determines the fair market value of any distribution for
purposes of this Section 8.04(c) by reference to the actual or when issued trading market for any
securities, it must in doing so consider the prices in such market over the same period used in
determining SP0 above.

          With respect to an adjustment pursuant to this Section 8.04(c) where there has been a payment
of a dividend or other distribution on the Common Shares in shares of beneficial interest any class
or series, or similar equity interest, of or relating to a Subsidiary or other business unit (a
“Spin-Off”), unless the Company distributes such shares of beneficial interest or equity interests
to each Noteholder on the same basis as such Noteholder would have received had it converted its
Notes solely into Common Shares immediately prior to such dividend or distribution, the Conversion
Rate in effect immediately before 5:00 p.m., New York City time, on the Record Date fixed for
determination of shareholders entitled to receive the distribution will be increased based on the
following formula:

	 	 	 	 	 	 	 
	 

	 	where	 	 	 	 
	 
	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to such
distribution;
	 
	 	 	 	 	 	 
	 

	 	CR¢
	 	=
	 	the Conversion Rate in effect immediately after such distribution;

26

 

	 	 	 	 	 	 	 
	 

	 	FMV0
	 	=
	 	the average of the Last Reported Sale Prices of the shares of
beneficial interest or similar equity interest distributed to holders of Common
Shares applicable to one Common Share over the first ten consecutive Trading
Day period after the effective date of the Spin-Off; and
	 
	 

	 	MP0
	 	=
	 	the average of the Last Reported Sale Prices of Common Shares over
the first ten consecutive Trading Day period after the effective date of the
Spin-Off.

Such adjustment shall occur on the tenth Trading Day from, and including, the effective date of the
Spin-Off; provided that in respect of any conversion within the ten Trading Days following any
Spin-Off, references within this paragraph (c) to ten days shall be deemed replaced with such
lesser number of Trading Days as have elapsed between such Spin-Off and the Conversion Date in
determining the applicable Conversion Rate.

          Rights or warrants distributed by the Company to all holders of Common Shares, entitling the
holders thereof to subscribe for or purchase Common Shares (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified event or events
(“Trigger Event”): (i) are deemed to be transferred with such Common Shares; (ii) are not
exercisable; and (iii) are also issued in respect of future issuances of Common Shares, shall be
deemed not to have been distributed for purposes of this Section 8.04 (and no adjustment to the
Conversion Rate under this Section 8.04 will be required) until the occurrence of the earliest
Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an
appropriate adjustment (if any is required) to the Conversion Rate shall be made under this
Section 8.04(c). If any such right or warrant, including any such existing rights or warrants
distributed prior to the date of this Fifth Supplemental Indenture, are subject to events, upon the
occurrence of which such rights or warrants become exercisable to purchase different securities,
evidences of indebtedness or other assets, then the date of the occurrence of any and each such
event shall be deemed to be the date of distribution and record date with respect to new rights or
warrants with such rights (and a termination or expiration of the existing rights or warrants
without exercise by any of the holders thereof). In addition, in the event of any distribution (or
deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type
described in the preceding sentence) with respect thereto that was counted for purposes of
calculating a distribution amount for which an adjustment to the Conversion Rate under this
Section 8.04 was made, (1) in the case of any such rights or warrants that shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be
readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger
Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or repurchase price received by a holder or holders of Common Shares with respect to such rights or
warrants (assuming such holder had retained such rights or warrants), made to all holders of Common
Shares as of the date of such redemption or repurchase, and (2) in the case of such rights or
warrants that shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

27

 

          For purposes of this Section 8.04(c), Section 8.04(a) and Section 8.04(b), any dividend or
distribution to which this Section 8.04(c) is applicable that also includes Common Shares to which
Section 8.04(a) applies or rights or warrants to subscribe for or purchase Common Shares to which
Section 8.04(a) or Section 8.04(b) applies (or both), shall be deemed instead to be (1) a dividend
or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such
Common Shares or rights or warrants to which Section 8.04(c) applies (and any Conversion Rate
adjustment required by this Section 8.04(c) with respect to such dividend or distribution shall
then be made) immediately followed by (2) a dividend or distribution of such Common Shares or such
rights or warrants (and any further Conversion Rate adjustment required by Section 8.04(a) and
Section 8.04(b) with respect to such dividend or distribution shall then be made), except (A) the
record date of such dividend or distribution shall be substituted as “the record date” and “the
date fixed for such determination” within the meaning of Section 8.04(a) and Section 8.04(b) and
(B) any Common Shares included in such dividend or distribution shall not be deemed “outstanding
immediately prior to such event” within the meaning of Section 8.04(a).

                (d) In case the Company shall pay a dividend or make a distribution consisting exclusively of
cash to all or substantially all holders of its Common Shares to the extent that the aggregate of
all such cash dividends or distributions paid in any quarter exceeds the Dividend Threshold Amount
for such quarter, the Conversion Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 
	 

	 	where	 	 	 	 
	 
	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the record date
for such distribution;
	 
	 	 	 	 	 	 
	 

	 	CR¢
	 	=
	 	the Conversion Rate in effect immediately after the record date for such
distribution;
	 
	 

	 	SP0
	 	=
	 	the average of the Last Reported Sale Prices of the Common Shares
over the period of ten consecutive Trading Days ending the Business Day
immediately preceding the record date (as defined in clause (f) of this
Section) for such distribution (or, if earlier, the Ex-Date relating to such
distribution);
	 
	 	 	 	 	 	 
	 

	 	T
	 	=
	 	the dividend threshold amount (“Dividend Threshold Amount”),
which amount shall initially be $0.46 per quarter and which shall be
appropriately adjusted from time to time for any share dividends on, or
subdivisions or combinations of, Common Shares; provided, that if a Conversion
Rate adjustment is required to be made as a result of a distribution that is
not a quarterly dividend either in whole or in part, the Dividend Threshold
Amount shall be deemed to be zero; and

28

 

	 	 	 	 	 	 	 
	 

	 	C
	 	=
	 	the amount in cash per share that the Company distributes to
holders of Common Shares.

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the
record date for such dividend or distribution; provided that if the portion of the cash so
distributed applicable to one Common Share is equal to or greater than SP0 above, in
lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall
have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash
such Holder would have received had such Holder owned a number of shares equal to the Conversion
Rate on the record date. If such dividend or distribution is not so paid or made, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared.

          For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any
reclassification of the Common Shares, as a result of which the Notes become convertible into more
than one class of Common Shares, if an adjustment to the Conversion Rate is required pursuant to
this Section 8.04(d), references in this Section to one Common Share or Last Reported Sale Price of
one Common Share shall be deemed to refer to a unit or to the price of a unit consisting of the
number of shares of each class of Common Shares into which the Notes are then convertible equal to
the number of shares of such class issued in respect of one Common Share in such reclassification.
The above provisions of this paragraph shall similarly apply to successive reclassifications.

                (e) In case the Company or any of its Subsidiaries makes a payment in respect of a tender
offer or exchange offer for all or any portion of the Common Shares, to the extent that the cash
and value of any other consideration included in the payment per Common Share exceeds the Last
Reported Sale Price of the Common Shares on the Trading Day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended),
the Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 	 	 
	 

	 	where	 	 	 	 
	 
	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect on the date such tender or exchange
offer expires;
	 
	 	 	 	 	 	 
	 

	 	CR¢
	 	=
	 	the Conversion Rate in effect on the day next succeeding the date such
tender or exchange offer expires;
	 
	 	 	 	 	 	 
	 

	 	AC
	 	=
	 	the aggregate value of all cash and any other consideration
(as determined by the Board of Trustees) paid or payable for shares purchased
in such tender or exchange offer;

29

 

	 	 	 	 	 	 	 
	 

	 	OS0
	 	=
	 	the number of Common Shares outstanding immediately prior to the
date such tender or exchange offer expires;
	 
	 	 	 	 	 	 
	 

	 	OS¢
	 	=
	 	the number of Common Shares outstanding immediately after the date such
tender or exchange offer expires; and
	 
	 	 	 	 	 	 
	 

	 	SP¢
	 	=
	 	the average of the Last Reported Sale Prices of Common Shares over the
ten consecutive Trading Day period commencing on the Trading Day next
succeeding the date such tender or exchange offer expires,

such adjustment to become effective immediately prior to the opening of business on the day
following the last date on which tenders or exchanges may be made pursuant to such tender or
exchange offer. If the Company is obligated to purchase shares pursuant to any such tender or
exchange offer, but the Company is permanently prevented by applicable law from effecting all or
any such purchases or all or any portion of such purchases are rescinded, the Conversion Rate shall
again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange
offer had not been made or had only been made in respect of the purchases that had been effected.
No adjustment to the Conversion Rate will be made if the application of the foregoing formulae
would result in a decrease in the Conversion Rate.

          (f) For purposes of this Section 8.04 the term “record date” shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of Common Shares have the
right to receive any cash, securities or other property or in which the Common Shares (or other
applicable security) is converted for or converted into any combination of cash, securities or
other property, the date fixed for determination of shareholders entitled to receive such cash,
securities or other property (whether such date is fixed by the Board of Trustees or by statute,
contract or otherwise).

          (g) In addition to those required by clauses (a), (b), (c), (d), and (e) of this Section 8.04,
and to the extent permitted by applicable law and subject to the applicable rules of the New York
Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a
period of at least 20 days if the Board of Trustees determines that such increase would be in the
Company’s best interest. In addition, the Company may also (but is not required to) increase the
Conversion Rate to avoid or diminish any income tax to holders of Common Shares or rights to
purchase Common Shares in connection with any dividend or distribution of shares (or rights to
acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to the Holder of each Note at his last address appearing
on the Security Register a notice of the increase at least five days prior to the date the
increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate
and the period during which it will be in effect.

          (h) All calculations and other determinations under this Article VIII shall be made by the
Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a
share, as the case may be. No adjustment shall be made for the Company’s issuance of Common Shares
or any securities convertible into or exchangeable for Common Shares, or the right to purchase
Common Shares or such convertible or exchangeable

30

 

securities, other than as provided in this Section 8.04. No adjustment shall be made to the
Conversion Rate unless such adjustment would require a change of at least 1% in the Conversion Rate
then in effect at such time. The Company shall carry forward any adjustments that are less than 1%
of the Conversion Rate and make such carried forward adjustments, regardless of whether the
aggregate adjustment is less than 1% within one year of the first such adjustment carried forward,
upon a Fundamental Change, upon any call of the notes for redemption or upon maturity.

          (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. The Trustee and Conversion Agent may conclusively rely on the
accuracy of the Conversion Rate adjustment provided by the Company. Unless and until a Responsible
Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be
deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry
that the last Conversion Rate of which it has knowledge is still in effect. Promptly after
delivery of such certificate, the Company shall prepare a notice of such adjustment of the
Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the
Holder of each Note at his last address appearing on the Security Register, within thirty (30) days
of the effective date of such adjustment. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment.

          (j) For purposes of this Section 8.04, the number of Common Shares at any time outstanding
shall not include shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of Common Shares.

     Notwithstanding the foregoing provisions of this Section 8.04, in no event will the total
number of Common Shares issuable upon conversion exceed 14.6349 per $1,000 principal amount of
Notes (subject to adjustment in the same manner or as set forth in clauses (a), (b) and (c) of this
Section 8.04).

     Section 8.05 Shares to be Fully Paid. Subject to Section 8.02(k), the Company shall provide,
free from preemptive rights, sufficient Common Shares to provide for conversion of the Notes from
time to time as such Notes are presented for conversion.

     Section 8.06 Effect of Reclassification, Consolidation, Merger or Sale. If any of the
following events occur, namely (i) any reclassification or change of the outstanding Common Shares
(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 split, subdivision or combination), (ii) any consolidation, merger or
combination of the Company with another Person, or (iii) any sale or conveyance of all or
substantially all of the property and assets of the Company to any other Person, in either case as
a result of which holders of Common Shares shall be entitled to receive cash, securities or other
property or assets with respect to or in exchange for such Common Shares (any such event a “Merger
Event”), then:

31

 

          (a) the Company or the successor or purchasing Person, as the case may be, shall execute with
the Trustee a supplemental indenture (which, as evidenced in an Opinion of Counsel delivered to the
Trustee, shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so comply) providing for
the conversion and settlement of the Notes as set forth in this Fifth Supplemental Indenture. Such
supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article and the Trustee may conclusively rely
on the determination by the Company of the equivalency of such adjustments. If, in the case of any
Merger Event, the Reference Property includes shares of stock or other securities and assets of a
corporation other than the successor or purchasing corporation, as the case may be, in such
reclassification, change, consolidation, merger, combination, sale or conveyance, then such
supplemental indenture shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Notes as the Board of Trustees
shall reasonably consider necessary by reason of the foregoing, including to the extent required by
the Board of Trustees and practicable the provisions providing for the repurchase rights set forth
in Article 9 herein.

     In the event the Company shall execute a supplemental indenture pursuant to this Section 8.06,
the Company shall, in addition to the Officers’ Certificate and Opinion of Counsel required by
Section 102 of the Base Indenture, file with the Trustee an Officers’ Certificate briefly stating
the kind or amount of cash, securities or property or asset that will constitute the Reference
Property after any such Merger Event, any adjustment to be made with respect thereto, and the
Trustee shall promptly mail notice thereof to all Noteholders.

          (b) Notwithstanding the provisions of Section 8.02(a) and Section 8.02(b), and subject to the
provisions of Section 8.01, at the effective time of such Merger Event, the right to convert each
$1,000 principal amount of Notes will be changed to a right to convert such Note by reference to
the kind and amount of cash, securities or other property or assets that a holder of a number of
Common Shares equal to the Conversion Rate immediately prior to such transaction would have owned
or been entitled to receive (the “Reference Property”) such that from and after the effective time
of such transaction, a Noteholder will be entitled thereafter to convert its Notes, subject to the
successor’s right to deliver cash, Common Shares or common stock of such successor or a combination
of cash and Common Shares as set forth in Section 8.02(b), into cash (up to the aggregate principal
amount thereof) and, in lieu of the Common Shares otherwise deliverable, the same type (and in the
same proportion) of Reference Property, based on the Daily Settlement Amounts of Reference Property
in an amount equal to the applicable Conversion Rate, as described under Section 8.02(b). For
purposes of determining the constitution of Reference Property, the type and amount of
consideration that a holder of Common Shares would have been entitled to in the case of
reclassifications, consolidations, mergers, sales or conveyance of assets or other transactions
that cause the Common Shares to be converted into the right to receive more than a single type of
consideration (determined based in part upon any form of shareholder election) will be deemed to be
the weighted average of the types and amounts of consideration received by the holders of Common
Shares that affirmatively make such an election. The Company shall not become a party to any such
transaction unless its terms are consistent with the preceding. None of the foregoing provisions
shall affect the right of a Holder of Notes to convert its Notes in accordance with the provisions
of Article VIII hereof prior to the effective date.

32

 

          (c) The Company shall cause notice of the execution of such supplemental indenture to be
mailed to each Noteholder, at his address appearing on the Security Register, within thirty (30)
days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.

          (d) The above provisions of this Section shall similarly apply to successive Merger Events.

     Section 8.07 Certain Covenants. The Company covenants that all Common Shares delivered upon
conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes,
liens and changes with respect to the issue thereof.

     Section 8.08 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not
at any time be under any duty or responsibility to any Noteholder to determine the Conversion Rate
or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect
to the nature or extent or calculation of any such adjustment when made, or with respect to the
method employed, or herein or in any supplemental indenture provided to be employed, in making the
same. The Trustee and any other Conversion Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any Common Shares, or of any securities or property,
which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and
any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor
any Conversion Agent shall be responsible for any failure of the Company to transfer or deliver any
Common Shares or share certificates or other securities or property or cash upon the surrender of
any Note for the purpose of conversion or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article.

     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 8.06 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Noteholders upon the
conversion of their Notes after any event referred to in such Section 8.06 or to any adjustment to
be made with respect thereto, but, subject to the provisions of Article Six of the Base Indenture,
may accept as conclusive evidence of the correctness of any such provisions, and shall be protected
in relying upon, the Officers’ Certificate with respect thereto.

     Section 8.09 Notice to Holders Prior to Certain Actions.

     In case:

          (a) the Company shall declare a dividend (or any other distribution) on its Common Shares that
would require an adjustment in the Conversion Rate pursuant to Section 8.04; or

          (b) the Company shall authorize the granting to all of the holders of its Common Shares of
rights or warrants to subscribe for or purchase any share of any class or any other rights or
warrants;

33

 

          (c) of any reclassification of the Common Shares of the Company (other than a subdivision or
combination of its outstanding Common Shares, or a change in par value, or from par value to no par
value, or from no par value to par value), or of any consolidation or merger to which the Company
is a party and for which approval of any shareholders of the Company is required, or of the sale or
transfer of all or substantially all of the assets of the Company; or

          (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company,

the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at his
address appearing on the Security Register as promptly as possible but in any event at least thirty
(30) days prior to the applicable date specified in clause (x) or (y) below, as the case may be, a
notice stating (x) the date on which a record is to be taken for the purpose of such dividend,
distribution or rights or warrants, or, if a record is not to be taken, the date as of which the
holders of Common Shares of record to be entitled to such dividend, distribution or rights are to
be determined, or (y) the date on which such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the
date as of which it is expected that holders of Common Shares of record shall be entitled to
convert their Common Shares for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.

     Section 8.10 Shareholder Rights Plans. Upon conversion of the Notes, the Holders shall
receive, in addition to any Common Shares issuable upon such conversion, the associated rights
issued under any future shareholder rights plan the Company adopts unless, prior to conversion, the
rights have separated from the Common Shares, expired, terminated or been redeemed or converted in
accordance with such rights plan. If, and only if, the Holders receive rights under such
shareholder rights plans as described in the preceding sentence upon conversion of their Notes,
then no other adjustment pursuant to this Article VIII shall be made in connection with such
shareholder rights plans.

     Section 8.11 Ownership Limit. Notwithstanding any other provision of this Fifth Supplemental
Indenture or the Notes, no Holder of Notes (or beneficial owner of Notes) shall be entitled to
convert such Notes for Common Shares to the extent that receipt of such shares would cause such
Holder (or beneficial owner of Notes) (together with such Holder’s (or beneficial owner’s)
affiliates) to exceed the applicable ownership limit contained in the declaration of trust of the
Company.

ARTICLE IX

REPURCHASE OF NOTES AT OPTION OF HOLDERS

     Section 9.01 Repurchase of Securities at Option of the Holder on Specified Dates.

          (a) The provisions of Article Thirteen of the Base Indenture shall not be applicable to the
Notes.

          (b) Each Noteholder shall have the right, at such Holder’s option, to require the Company to
repurchase all of such Holder’s Notes or any portion thereof that is a multiple of $1,000 principal
amount, for cash on January 15, 2013, November 15, 2017, November 15, 2022, November 15, 2027 and
November 15, 2032 (each, a “Put Right Repurchase Date”) at a repurchase price per Note equal to
100% of the aggregate principal amount of the Notes being repurchased, together with any accrued
and unpaid interest up to, but not including, such Put Right Repurchase Date (the “Put Right
Repurchase Price”).

     Repurchases of Notes by the Company pursuant to this Section 9.01 shall be made, at the option
of the Holder thereof, upon:

                     (i) delivery to the Trustee (or other Paying Agent appointed by the Company)
by the Holder of a written notice of purchase (a “Put Right Repurchase Notice”) in
the form set forth on the reverse of the Note at any time from the opening of
business on the date that is 25 Business Days prior to the applicable Put Right
Repurchase Date until the close of business on the fifth Business Day prior to such
Put Right Repurchase Date stating:

                    (A) if certificated, the certificate numbers of the Notes to be
delivered for repurchase;

                     (B) the portion of the principal amount of the Notes to be
repurchased, which must be $1,000 or an integral multiple thereof, and

                    (C) that the Notes are to be repurchased as of the applicable Put
Right Repurchase Date pursuant to the terms and conditions specified in
the Notes and in this Fifth Supplemental Indenture, and

                     (ii) delivery of such Note to the Paying Agent prior to, on or after the Put
Right Repurchase Date (together with all necessary endorsements) at the offices of
the Paying Agent, such delivery being a condition to receipt by the Holder of the
Put Right Repurchase Price therefor, which shall be so paid pursuant to this
Section 9.01 only if the Note so delivered to the Paying Agent shall conform in all
respects to the description thereof in the related Put Right Repurchase Notice, as
determined by the Company.

35

 

     The Company shall repurchase from the Holder thereof, pursuant to this Section 9.01, a portion
of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Fifth Supplemental Indenture that apply to the repurchase of all of a Note also
apply to the repurchase of such portion of such Note.

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.01
shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Put Right Repurchase Date and the time of delivery of the Note.

     The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company
of the receipt by it of any Put Right Repurchase Notice or written notice of withdrawal thereof in
accordance with the provisions of Section 9.01(e).

     Any Note that is to be repurchased only in part shall be surrendered to the Trustee (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 his
attorney duly authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and make available for delivery to the Holder of such Note without service charge, a
new Note or Notes, containing identical terms and conditions, each in an authorized denomination in
aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal
of the Note so surrendered.

          (c) In connection with any purchase of Notes pursuant to this Section 9.01, the Company shall
give written notice of the Put Right Repurchase Date to the Holders (the “Company Put Right
Notice”).

     The Company Put Right Notice shall be sent by first-class mail to the Trustee and to each
Holder (and to each beneficial owner as required by applicable law) that has delivered a Put Right
Repurchase Notice within 10 Business Days of receipt of such Put Right Repurchase Notice, or, if a
shorter period, at least two Business Days prior to any Put Right Repurchase Date (the “Company Put
Right Notice Date”). Each Company Put Right Notice shall include a form of Put Right Repurchase
Notice to be completed by a Noteholder and shall state:

                     (i) the Put Right Repurchase Price and the Conversion Price;

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

                     (iii) that Notes as to which a Put Right Repurchase Notice has been given may
be converted in accordance with Article VIII hereof only if the applicable Put
Right Repurchase Notice has been withdrawn in accordance with the terms of this
Fifth Supplemental Indenture;

                     (iv) that Notes must be surrendered to the Paying Agent to collect payment;

36

 

               (v) that the Put Right Repurchase Price for any Note as to which a Put Right
Repurchase Notice has been given and not withdrawn will be paid promptly following
the later of the Put Right Repurchase Date and the time of surrender of such Note
as described in subclause (iv) above;

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

               (vii) briefly, the conversion rights of the Notes;

               (viii) the procedures for withdrawing a Put Right Repurchase Notice (including
pursuant to the terms of Section 9.01(e);

               (ix) that, unless the Company defaults in making payment on Notes for which a
Put Right Repurchase Notice has been submitted, interest on the Notes in respect of
which a Put Right Repurchase Notice has been delivered and not withdrawn will cease
to accrue on the Put Right Repurchase Date; and

               (x) the CUSIP number of the Notes.

          If any of the Notes are to be redeemed in the form of a Global Note, the Company shall modify
such notice to the extent necessary to accord with the procedures of the Depositary applicable to
redemptions.

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

               (d) Upon receipt by the Trustee (or other Paying Agent appointed by the Company) of the Put
Right Repurchase Notice specified in Section 9.01(a), the Holder of the Note in respect of which
such Put Right Repurchase Notice was given shall (unless such Put Right Repurchase Notice is
withdrawn as specified in Section 9.01(e)) thereafter be entitled to receive solely the Put Right
Repurchase Price with respect to such Note. Such Put Right Repurchase Price shall be paid to such
Holder, subject to receipt of funds by the Paying Agent, promptly following the later of (x) the
Put Right Repurchase Date with respect to such Note (provided the conditions in Section 9.01(a)
have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder
thereof in the manner required by Section 9.01(a). Notes in respect of which a Put Right Repurchase
Notice has been given by the Holder thereof may not be converted pursuant to Article VIII hereof on
or after the date of the delivery of such Put Right Repurchase Notice, unless such Put Right
Repurchase Notice has first been validly withdrawn as specified in Section 9.01(e).

               (e) A Put Right Repurchase Notice may be withdrawn by means of a written notice of withdrawal
delivered to the office of the Paying Agent in accordance with the
Put Right Repurchase Notice at any time prior to 10:00 A.M. New York City time on the fourth
Business Day prior to the Put Right Repurchase Date specifying:

37

 

               (i) if certificated Notes have been issued, the certificate numbers of the
withdrawn Notes,

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

               (iii) the principal amount, if any, of such Notes that remains subject to the
original Put Right Repurchase Notice, which portion must be in principal amounts of
$1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with
appropriate procedures of the Depositary.

          A written notice of withdrawal of a Put Right Repurchase Notice shall be in the form set forth
in the preceding paragraph.

          Upon receipt of a written notice of withdrawal, the Paying Agent shall promptly return to the
Holders thereof any Notes in respect of which a Put Right Repurchase Notice has been withdrawn in
accordance with the provisions of Section 9.01(f).

               (f) There shall be no repurchase of any Notes pursuant to this Section 9.01 if there has
occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of
the required Put Right Repurchase Notice) and is continuing an Event of Default with respect to
Notes (other than a default in the payment of the Put Right Repurchase Price with respect to such
Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes held by
it during the continuance of an Event of Default with respect to Notes (other than a default in the
payment of the Put Right Repurchase Price with respect to such Notes), in which case, upon such
return, the Put Right Repurchase Notice with respect thereto shall be deemed to have been
withdrawn.

               (g) Prior to 11:00 a.m. (local time in The City of New York) on the Put Right Repurchase Date,
the Company shall deposit with the Trustee (or other Paying Agent appointed by the Company or if
the Company is acting as its own Paying Agent, set aside, segregate and hold in trust in accordance
with the terms of the Base Indenture as modified by this Fifth Supplemental Indenture) an amount
(in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate
Put Right Repurchase Price of all the Notes or portions thereof which are to be purchased as of the
Put Right Repurchase Date. The manner in which the deposit required by this Section 9.01(g) is
made by the Company shall be at the option of the Company; provided that such deposit shall be made
in a manner such that the Trustee or a Paying Agent shall have immediately available funds on the
Put Right Repurchase Date.

          If the Trustee (or other Paying Agent appointed by the Company) holds, in accordance with the
terms hereof, money sufficient to pay the Put Right Repurchase Price of any Note, then, on the Put
Right Repurchase Date, such Note will cease to be Outstanding and the
rights of the Holder in respect thereof shall terminate (other than the right to receive the
Put Right Repurchase Price as aforesaid).

38

 

          To the extent that the aggregate amount of cash deposited by the Company pursuant to this
Section 9.01(g) exceeds the aggregate Put Right Repurchase Price of the Notes or portions thereof
that the Company is obligated to purchase, then promptly after the Put Right Repurchase Date the
Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company.

          Section 1.02 Repurchase at Option of Holders Upon a Fundamental Change.

               (a) If a Fundamental Change occurs at any time, then each Noteholder shall have the right, at
such Holder’s option, to require the Company to repurchase all of such Holder’s Notes or any
portion thereof that is a multiple of $1,000 principal amount, for cash on the date (the
"Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty (20)
Business Days and not more than thirty-five (35) Business Days after the date of the Fundamental
Change Company Notice (as defined below) at a repurchase price equal to 100% of the principal
amount thereof, together with accrued and unpaid interest thereon to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”).

          Repurchases of Notes under this Section 9.02 shall be made, at the option of the Holder
thereof, upon:

               (i) delivery to the Trustee (or other Paying Agent appointed by the Company)
by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”)
in the form set forth on the reverse of the Note prior to the close of business on
the Fundamental Change Repurchase Date; and

               (ii) delivery or book-entry transfer of the Notes to the Trustee (or other
Paying Agent appointed by the Company) at any time after delivery of the
Fundamental Change Repurchase Notice (together with all necessary endorsements) at
the Corporate Trust Office of the Trustee (or other Paying Agent appointed by the
Company) in the Borough of Manhattan or the City of Boston, such delivery being a
condition to receipt by the Holder of the Fundamental Change Repurchase Price
therefor; provided that such Fundamental Change Repurchase Price shall be so paid
pursuant to this Section 9.02 only if the Note so delivered to the Trustee (or
other Paying Agent appointed by the Company) shall conform in all respects to the
description thereof in the related Fundamental Change Repurchase Notice.

The Fundamental Change Repurchase Notice shall state:

               (A) if certificated, the certificate numbers of Notes to be
delivered for repurchase;

               (B) the portion of the principal amount of Notes to be repurchased,
which must be $1,000 or an integral multiple thereof; and

39

 

               (C) that the Notes are to be repurchased by the Company pursuant to
the applicable provisions of the Notes and this Fifth Supplemental
Indenture.

          Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.02
shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Fundamental Change Repurchase Date and the time of the book-entry
transfer or delivery of the Note.

          The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company
of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal
thereof in accordance with the provisions of Section 9.02(c).

          Any Note that is to be repurchased only in part shall be surrendered to the Trustee (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 his
attorney duly authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and make available for delivery to the Holder of such Note without service charge, a
new Note or Notes, containing identical terms and conditions, each in an authorized denomination in
aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal
of the Note so surrendered.

               (b) On or before the twentieth day after the occurrence of any Fundamental Change, the Company
shall provide to all Holders of record of the Notes and the Trustee and Paying Agent a notice (the
"Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the
repurchase right at the option of the Holders arising as a result thereof. Such mailing shall be by
first class mail. Simultaneously with providing such Fundamental Change Company Notice, the
Company shall publish a notice containing the information included therein once in a newspaper of
general circulation in The City of New York or publish such information on the Company’s website or
through such other public medium as the Company may use at such time.

          Each Fundamental Change Company Notice shall specify:

               (i) the events causing the Fundamental Change;

               (ii) the date of the Fundamental Change;

               (iii) that the Holder must exercise the repurchase right on or prior to the
close of business on the Fundamental Change Repurchase Date;

               (iv) the Fundamental Change Repurchase Price;

               (v) the Fundamental Change Repurchase Date;

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

40

 

               (vii) the applicable Conversion Rate and any adjustments to the applicable
Conversion Rate;

               (viii) that the Notes with respect to which a Fundamental Change Repurchase
Notice has been delivered by a Holder may be converted only if the Holder withdraws
the Fundamental Change Repurchase Notice in accordance with the terms of this Fifth
Supplemental Indenture; and

               (ix) the procedures that Holders must follow to require the Company to
repurchase their Notes.

          No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 9.02.

               (c) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the Trustee and Paying Agent in accordance with the Fundamental Change
Company Notice at any time prior to the close of business on the Business Day prior to the
Fundamental Change Repurchase Date, specifying:

               (i) the principal amount of the Notes with respect to which such notice of
withdrawal is being submitted;

               (ii) if certificated Notes have been issued, the certificate numbers of the
withdrawn Notes; and

               (iii) the principal amount, if any, of such Notes that remains subject to the
original Fundamental Change Repurchase Notice, which portion must be in principal
amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with
appropriate procedures of the Depositary.

               (d) On or prior to 11:00 a.m. (local time in The City of New York) on the second Business Day
following the Fundamental Change Repurchase Date, the Company will deposit with the Trustee (or
other Paying Agent appointed by the Company or if the Company is acting as its own Paying Agent,
set aside, segregate and hold in trust in accordance with the Base Indenture as modified by this
Fifth Supplemental Indenture) an amount of money sufficient to repurchase on the Fundamental Change
Repurchase Date all of the Notes to be repurchased on such date at the Fundamental Change
Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent
appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn) prior
to the close of business on the Fundamental Change Repurchase Date will be made promptly after the
later of (x) the
Fundamental Change Repurchase Date with respect to such Note (provided the Holder has
satisfied the conditions to the payment of the Fundamental Change Repurchase Price in
Section 9.02), and (y) the time of book-entry transfer or the delivery of such Note to the Trustee
(or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by
Section 9.02 by mailing checks for the amount payable to the Holders of such Notes entitled

41

 

thereto
as they shall appear in the Security Register, provided, however, that payments to the Depositary
shall be made by wire transfer of immediately available funds to the account of the Depositary or
its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company,
return to the Company any funds in excess of the Fundamental Change Repurchase Price.

               (e) If the Trustee (or other Paying Agent appointed by the Company) holds money or securities
sufficient to repurchase on the Fundamental Change Repurchase Date all the Notes or portions
thereof that are to be purchased as of the second Business Day following the Fundamental Change
Repurchase Date, then on and after the Fundamental Change Repurchase Date (i) such Notes will cease
to be Outstanding, (ii) interest will cease to accrue on such Notes, and (iii) all other rights of
the Holders of such Notes will terminate, whether or not book-entry transfer of the Notes has been
made or the Notes have been delivered to the Trustee or Paying Agent, other than the right to
receive the Fundamental Change Repurchase Price upon delivery of the Notes.

[FORM OF REVERSE OF NOTE]

PROLOGIS

1.875% Convertible Senior Notes due 2037

          This Security is one of a duly authorized issue of Securities of the Company, designated as
its 1.875% Convertible Senior Notes due 2037 (herein called the “Securities”), issued under and
pursuant to an Indenture dated as of March 1, 1995, as supplemented with respect to the Securities
by the Second Supplemental Indenture, dated as of November 2, 2005 and the Fifth Supplemental
Indenture, dated as of November 8, 2007 (as so supplemented, herein called the “Indenture”),
between the Company and U.S. Bank National Association (herein called the “Trustee”), to which
Indenture and all indentures supplemental thereto reference is hereby made for a description of the
rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities. Additional Securities may be issued in an unlimited
aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized
terms used but not defined herein shall have the meanings ascribed to them in the Indenture.

          In case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal of and interest on all Securities may be declared, and upon said
declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

          Prior to January 15, 2013, the Company may not redeem the Securities except to preserve the
Company’s status as a real estate investment trust as described in Section 3.01 of the Fifth
Supplemental Indenture. Subject to the terms and conditions of the Indenture, on or after January
15, 2013, the Company shall have the right to redeem the Securities, in whole or from time to time
in part, at a price equal to 100% of the principal amount of the Securities being redeemed, plus
accrued and unpaid interest. Any such redemption shall be upon at least 30 days’ and no more than
60 days’ notice to Holders of the Securities.

          Subject to the terms and conditions of the Indenture, the Company will make all payments and
deliveries in respect of the Fundamental Change Repurchase Price, the Put Right Repurchase Price,
the Redemption Price and the principal amount on the Maturity Date, as the case may be, to the
Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the
Security. The Company will pay cash amounts in money of the United States that at the time of
payment is legal tender for payment of public and private debts.

          The Indenture contains provisions permitting the Company and the Trustee in certain
circumstances, without the consent of the Holders of the Securities, and in other circumstances,
with the consent of the Holders of not less than a majority in principal amount of the Securities
at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
adding any provisions to or changing in any manner or eliminating any of the provisions of the
Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of
the Securities; provided, however, that no such supplemental

Exh. A-6

 

indenture shall make any of the changes set forth in Section 6.02 of the Fifth Supplemental
Indenture, without the consent of each Holder of an Outstanding Security affected thereby. It is
also provided in the Indenture that, prior to any declaration accelerating the maturity of the
Securities, the Holders of a majority in principal amount of the Securities at the time Outstanding
may on behalf of the Holders of all of the Securities waive any past default or Event of Default
under the Indenture and its consequences except as provided in the Indenture. Any such consent or
waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and owners of this Security and
any Securities which may be issued in exchange or substitution hereof, irrespective of whether or
not any notation thereof is made upon this Security or such other Securities.

          No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and accrued and unpaid interest on this Security at the place, at the respective
times, at the rate and in the lawful money herein prescribed.

          The Securities are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred
to on the face hereof, and in the manner and subject to the limitations provided in the Indenture,
without payment of any service charge but with payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any registration or exchange of
Securities, Securities may be exchanged for a like aggregate principal amount of Securities of
other authorized denominations.

          The Securities are not subject to redemption through the operation of any sinking fund.

          Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s
option, to require the Company to repurchase all of such Holder’s Securities or any portion thereof
(in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase
Date at a price equal to 100% of the principal amount of the Securities such holder elects to
require the Company to repurchase, together with accrued and unpaid interest to but excluding the
Fundamental Change Repurchase Date. The Company or, at the written request of the Company, the
Trustee shall mail to all Holders of record of the Securities a notice of the occurrence of a
Fundamental Change and of the repurchase right arising as a result thereof on or before the
twentieth day after the occurrence of any Fundamental Change.

of such Holder’s Securities or any portion thereof (in principal amounts of $1,000 or integral

the Paying Agent at any time from the opening of business on the date that is 25 Business Days
prior to the applicable Put Right Repurchase Date until the close of business on the fifth Business
Day prior to the Put Right Repurchase Date.

          Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, on
and after October 15, 2012, or earlier upon the occurrence of certain conditions specified in the
Indenture and prior to the close of business on the Trading Day immediately preceding the Maturity
Date, to convert any Securities or portion thereof which is $1,000 or an integral multiple thereof,
into cash, Common Shares or a combination of cash and Common Shares, at the option of the Company
as provided in the Fifth Supplemental Indenture, in each case at the Conversion Rate specified in
the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this
Security, together with a Notice of Conversion, a form of which is attached to this Security, as
provided in the Indenture and this Security, to the Company at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, City of New York or the City of Boston or
elsewhere as provided in the Indenture, and, unless the shares issuable on conversion are to be
issued in the same name as this Security, duly endorsed by, or accompanied by instruments of
transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized
attorney. The initial Conversion Rate is 12.1957 shares for each $1,000 principal amount of
Securities. No fractional Common Shares will be issued upon any conversion, but an adjustment in
cash will be paid to the Holder, as provided in the Indenture, in respect of any fraction of a
share which would otherwise be issuable upon the surrender of any Security or Securities for
conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such
Security except as provided in the Indenture.

          Upon due presentment for registration of transfer of this Security at the office or agency of
the Company in the Borough of Manhattan, City of New York or the City of Boston, a new Security or
Securities of authorized denominations for an equal aggregate principal amount will be issued to
the transferee in exchange thereof, subject to the limitations provided in the Indenture, without
charge except for any tax, assessments or other governmental charge imposed in connection
therewith.

          The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and
any Security Registrar may deem and treat the registered Holder hereof as the absolute owner of
this Security (whether or not this Security shall be overdue and notwithstanding any notation of
ownership or other writing hereon), for the purpose of receiving payment hereof, or on account
hereof, for the conversion hereof and for all other purposes, and neither the Company nor the
Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor
any Security Registrar shall be affected by any notice to the contrary. All payments made to or
upon the order of such registered Holder shall, to the extent of the sum or sums paid, satisfy and
discharge liability for monies payable on this Security.

          No recourse for the payment of the principal of, or accrued and unpaid interest on, this
Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or
upon any obligation, covenant or agreement of the Company in the Indenture or any indenture
supplemental thereto or in any Security, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, stockholder, employee, agent, officer, trustee,
director or subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law or by the enforcement of any

Exh. A-8

 

assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as
part of the consideration for the issue hereof, expressly waived and released.

          Terms used in this Security and defined in the Indenture are used herein as therein defined.

          Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM
(=tenants in common), TENANT (=tenants by the entireties), JT TEN (joint tenants with right of

ARTICLE IV

Shares Subject to the Plan

     4.1 Number of Shares; Award Limits. Subject to the provisions of this Article IV, the maximum
number of shares of Common Stock with respect to which Awards may be granted during the term of the
Plan shall be 20 million shares. Shares of Common Stock will be made available from the authorized
but unissued shares of the Company or from shares reacquired by the Company, including shares
purchased in the open market. The shares of Common Stock subject to (i) any Award granted under
the Plan that shall expire, terminate or be annulled for any reason without having been exercised
(or considered to have been exercised as provided in Section 7.2), (ii) any Award of any SARs
granted under the Plan that shall be exercised for cash, and (iii) any Award of Restricted Shares
or Stock Units that shall be forfeited prior to becoming vested (provided that the Holder received
no benefits of ownership of such Restricted Shares or Stock Units other than voting rights and the
accumulation of Retained Distributions and unpaid Dividend Equivalents that are likewise forfeited)
shall again be available for purposes of the Plan. Except for Awards described in Section 11.1, no
person may be granted in any calendar year Awards covering more than 2 million shares of Common
Stock (as such amount may be adjusted from time to time as provided in Section 4.2). No person
shall receive payment for Cash Awards during any calendar year aggregating in excess of
$10,000,000.

     4.2 Adjustments. If the Company subdivides its outstanding shares of any series of Common
Stock into a greater number of shares of such series of Common Stock (by stock dividend, stock
split, reclassification, or otherwise) or combines its outstanding shares of any series of Common
Stock into a smaller number of shares of such series of Common Stock (by reverse stock split,
reclassification, or otherwise) or if the Committee determines that any stock dividend,
extraordinary cash dividend, reclassification, recapitalization, reorganization, split-up,
spin-off, combination, exchange of shares, warrants or rights offering to purchase such series of
Common Stock or other similar corporate event (including mergers or consolidations other than those
which constitute Approved Transactions, adjustments with respect to which shall be governed by
Section 11.1(b)) affects any series of Common Stock so that an adjustment is

-6-

 

required to preserve the benefits or potential benefits intended to be made available under
the Plan, then the Committee, in such manner as the Committee, in its sole discretion, deems
equitable and appropriate, shall make such adjustments to any or all of (i) the number and kind of
shares of stock which thereafter may be awarded, optioned or otherwise made subject to the benefits
contemplated by the Plan, (ii) the number and kind of shares of stock subject to outstanding
Awards, and (iii) the purchase or exercise price and the relevant appreciation base with respect to
any of the foregoing, provided, however, that the number of shares subject to any Award shall
always be a whole number. Notwithstanding the foregoing, if all shares of any series of Common
Stock are redeemed, then each outstanding Award shall be adjusted to substitute for the shares of
such series of Common Stock subject thereto the kind and amount of cash, securities or other assets
issued or paid in the redemption of the equivalent number of shares of such series of Common Stock
and otherwise the terms of such Award, including, in the case of Options or similar rights, the
aggregate exercise price, and, in the case of Free Standing SARs, the aggregate base price, shall
remain constant before and after the substitution (unless otherwise determined by the Committee and
provided in the applicable Agreement). The Committee may, if deemed appropriate, provide for a
cash payment to any Holder of an Award in connection with any adjustment made pursuant to this
Section 4.2.

ARTICLE V

Eligibility

     5.1 General. The persons who shall be eligible to participate in the Plan and to receive
Awards under the Plan shall, subject to Section 5.2, be such persons who are employees (including
officers) of or independent contractors providing services to the Company or its Subsidiaries as
the Committee shall select. Awards may be made to employees or independent contractors who hold or
have held Awards under the Plan or any similar or other awards under any other plan of the Company
or any of its Affiliates.

     5.2 Ineligibility. No member of the Committee, while serving as such, shall be eligible to
receive an Award.

ARTICLE VI

from time to time those eligible persons to be granted Options, the time when each Option shall be
granted to such eligible persons, the series and number of shares of Common Stock subject to such
Option, and, subject to Section 6.2, the purchase price of the shares of Common Stock subject to
such Option.

     6.2 Option Price. The price at which shares may be purchased upon exercise of an Option shall
be fixed by the Committee and may be no less than the Fair Market Value of the shares of the
applicable series of Common Stock subject to the Option as of the date the Option is granted.

     6.3 Term of Options. Subject to the provisions of the Plan with respect to death, retirement
and termination of employment, the term of each Option shall be for such period as the Committee
shall determine as set forth in the applicable Agreement.

     6.4 Exercise of Options. An Option granted under the Plan shall become (and remain)
exercisable during the term of the Option to the extent provided in the applicable Agreement and
the Plan and, unless the Agreement otherwise provides, may be exercised to the extent exercisable,
in whole or in part, at any time and from time to time during such term; provided, however, that
subsequent to the grant of an Option, the Committee, at any time before complete termination of
such Option, may accelerate the time or times at which such Option may be exercised in whole or in
part (without reducing the term of such Option).

     6.5 Manner of Exercise.

     (a) Form of Payment. An Option shall be exercised by written notice to the Company
upon such terms and conditions as the Agreement may provide and in accordance with such
other procedures for the exercise of Options as the Committee may establish from time to
time. The method or methods of payment of the purchase price for the shares to be purchased
upon exercise of an Option and of any amounts required by Section 11.9 shall be determined
by the Committee and may consist of (i) cash, (ii) check, (iii) promissory note (subject to
applicable law), (iv) whole shares of any series of Common Stock, (v) the withholding of
shares of the applicable series of Common Stock issuable upon such exercise of the Option,
(vi) the delivery, together with a properly executed exercise notice, of irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale or loan
proceeds required to pay the purchase price, or (vii) any combination of the foregoing
methods of payment, or such other consideration and method of payment as may be permitted
for the issuance of shares under the Delaware General Corporation Law. The permitted method
or methods of payment of the amounts payable upon exercise of an Option, if other than in
cash, shall be set forth in the applicable Agreement and may be subject to such conditions
as the Committee deems appropriate.

     (b) Value of Shares. Unless otherwise determined by the Committee and provided in the
applicable Agreement, shares of any series of Common Stock delivered in payment of all or
any part of the amounts payable in connection with the exercise of an Option, and shares of
any series of Common Stock withheld for such payment, shall be valued for such purpose at
their Fair Market Value as of the exercise date.

     (c) Issuance of Shares. The Company shall effect the transfer of the shares of Common
Stock purchased under the Option as soon as practicable after the exercise thereof and
payment in full of the purchase price therefor and of any amounts required by Section 11.9,
and within a reasonable time thereafter, such transfer shall be evidenced on the books of
the Company. Unless otherwise determined by the Committee and provided in the applicable
Agreement, (i) no Holder or other person exercising an Option shall have any of the rights
of a stockholder of the Company with respect to shares of Common

-8-

 

Stock subject to an Option granted under the Plan until due exercise and full payment
has been made, and (ii) no adjustment shall be made for cash dividends or other rights for
which the record date is prior to the date of such due exercise and full payment.

     6.6 Nontransferability. Unless otherwise determined by the Committee and provided in the
applicable Agreement, Options shall not be transferable other than by will or the laws of descent
and distribution or pursuant to a Domestic Relations Order, and, except as otherwise required
pursuant to a Domestic Relations Order, Options may be exercised during the lifetime of the Holder
thereof only by such Holder (or his or her court-appointed legal representative).

ARTICLE VII

SARs

     7.1 Grant of SARs. Subject to the limitations of the Plan, SARs may be granted by the
Committee to such eligible persons in such numbers, with respect to any specified series of Common
Stock, and at such times during the term of the Plan as the Committee shall determine. A SAR may
be granted to a Holder of an Option (hereinafter called a "related Option") with respect to all or
a portion of the shares of Common Stock subject to the related Option (a "Tandem SAR") or may be
granted separately to an eligible employee (a "Free Standing SAR"). Subject to the limitations of
the Plan, SARs shall be exercisable in whole or in part upon notice to the Company upon such terms
and conditions as are provided in the Agreement.

     7.2 Tandem SARs. A Tandem SAR may be granted either concurrently with the grant of the
related Option or at any time thereafter prior to the complete exercise, termination, expiration or
cancellation of such related Option. Tandem SARs shall be exercisable only at the time and to the
extent that the related Option is exercisable (and may be subject to such additional limitations on
exercisability as the Agreement may provide) and in no event after the complete termination or full
exercise of the related Option. Upon the exercise or termination of the related Option, the Tandem
SARs with respect thereto shall be canceled automatically to the extent of the number of shares of
Common Stock with respect to which the related Option was so exercised or terminated. Subject to
the limitations of the Plan, upon the exercise of a Tandem SAR and unless otherwise determined by
the Committee and provided in the applicable Agreement, (i) the Holder thereof shall be entitled to
receive from the Company, for each share of the applicable series of Common Stock with respect to
which the Tandem SAR is being exercised, consideration (in the form determined as provided in
Section 7.4) equal in value to the excess of the Fair Market Value of a share of the applicable
series of Common Stock with respect to which the Tandem SAR was granted on the date of exercise
over the related Option purchase price per share, and (ii) the related Option with respect thereto
shall be canceled automatically to the extent of the number of shares of Common Stock with respect
to which the Tandem SAR was so exercised.

     7.3 Free Standing SARs. Free Standing SARs shall be exercisable at the time, to the extent
and upon the terms and conditions set forth in the applicable Agreement. The base price of a Free
Standing SAR may be no less than the Fair Market Value of the applicable series of Common Stock
with respect to which the Free Standing SAR was granted as of the date the Free

-9-

 

Standing SAR is granted. Subject to the limitations of the Plan, upon the exercise of a Free
Standing SAR and unless otherwise determined by the Committee and provided in the applicable
Agreement, the Holder thereof shall be entitled to receive from the Company, for each share of the
applicable series of Common Stock with respect to which the Free Standing SAR is being exercised,
consideration (in the form determined as provided in Section 7.4) equal in value to the excess of
the Fair Market Value of a share of the applicable series of Common Stock with respect to which the
Free Standing SAR was granted on the date of exercise over the base price per share of such Free
Standing SAR.

     7.4 Consideration. The consideration to be received upon the exercise of a SAR by the Holder
shall be paid in the applicable series of Common Stock with respect to which the SAR was granted
(valued at Fair Market Value on the date of exercise of such SAR). No fractional shares of Common
Stock shall be issuable upon exercise of a SAR, and unless otherwise provided in the applicable
Agreement, the Holder will receive cash in lieu of fractional shares. Unless the Committee shall
otherwise determine, to the extent a Free Standing SAR is exercisable, it will be exercised
automatically on its expiration date.

     7.5 Limitations. The applicable Agreement may provide for a limit on the amount payable to a
Holder upon exercise of SARs at any time or in the aggregate, for a limit on the time periods
during which a Holder may exercise SARs, and for such other limits on the rights of the Holder and
such other terms and conditions of the SAR, including a condition that the SAR may be exercised
only in accordance with rules and regulations adopted from time to time, as the Committee may
determine. Unless otherwise so provided in the applicable Agreement, any such limit relating to a
Tandem SAR shall not restrict the exercisability of the related Option. Such rules and regulations
may govern the right to exercise SARs granted prior to the adoption or amendment of such rules and
regulations as well as SARs granted thereafter.

     7.6 Exercise. For purposes of this Article VII, the date of exercise of a SAR shall mean the
date on which the Company shall have received notice from the Holder of the SAR of the exercise of
such SAR (unless otherwise determined by the Committee and provided in the applicable Agreement).

     7.7 Nontransferability. Unless otherwise determined by the Committee and provided in the
applicable Agreement, (i) SARs shall not be transferable other than by will or the laws of descent
and distribution or pursuant to a Domestic Relations Order, and (ii) except as otherwise required
pursuant to a Domestic Relations Order, SARs may be exercised during the lifetime of the Holder
thereof only by such Holder (or his or her court-appointed legal representative).

ARTICLE VIII

Restricted Shares

     8.1 Grant. Subject to the limitations of the Plan, the Committee shall designate those
eligible persons to be granted Awards of Restricted Shares, shall determine the time when each such
Award shall be granted, shall determine whether shares of Common Stock covered by Awards of
Restricted Shares will be issued at the beginning or the end of the Restriction Period

-10-

 

and whether Dividend Equivalents will be paid during the Restriction Period in the event
shares of the applicable series of Common Stock are to be issued at the end of the Restriction
Period, and shall designate (or set forth the basis for determining) the Vesting Date or Vesting
Dates for each Award of Restricted Shares, and may prescribe other restrictions, terms and
conditions applicable to the vesting of such Restricted Shares in addition to those provided in the
Plan. The Committee shall determine the price, if any, to be paid by the Holder for the Restricted
Shares; provided, however, that the issuance of Restricted Shares shall be made for at least the
minimum consideration necessary to permit such Restricted Shares to be deemed fully paid and
nonassessable. All determinations made by the Committee pursuant to this Section 8.1 shall be
specified in the Agreement.

     8.2 Issuance of Restricted Shares at Beginning of the Restriction Period. If shares of the
applicable series of Common Stock are issued at the beginning of the Restriction Period, the stock
certificate or certificates representing such Restricted Shares shall be registered in the name of
the Holder to whom such Restricted Shares shall have been awarded. During the Restriction Period,
certificates representing the Restricted Shares and any securities constituting Retained
Distributions shall bear a restrictive legend to the effect that ownership of the Restricted Shares
(and such Retained Distributions), and the enjoyment of all rights appurtenant thereto, are subject
to the restrictions, terms and conditions provided in the Plan and the applicable Agreement. Such
certificates shall remain in the custody of the Company or its designee, and the Holder shall
deposit with the custodian stock powers or other instruments of assignment, each endorsed in blank,
so as to permit retransfer to the Company of all or any portion of the Restricted Shares and any
securities constituting Retained Distributions that shall be forfeited or otherwise not become
vested in accordance with the Plan and the applicable Agreement.

     8.3 Restrictions. Restricted Shares issued at the beginning of the Restriction Period shall
constitute issued and outstanding shares of the applicable series of Common Stock for all corporate
purposes. The Holder will have the right to vote such Restricted Shares, to receive and retain
such dividends and distributions, as the Committee may designate, paid or distributed on such
Restricted Shares, and to exercise all other rights, powers and privileges of a Holder of shares of
the applicable series of Common Stock with respect to such Restricted Shares; except, that, unless
otherwise determined by the Committee and provided in the applicable Agreement, (i) the Holder will
not be entitled to delivery of the stock certificate or certificates representing such Restricted
Shares until the Restriction Period shall have expired and unless all other vesting requirements
with respect thereto shall have been fulfilled or waived; (ii) the Company or its designee will
retain custody of the stock certificate or certificates representing the Restricted Shares during
the Restriction Period as provided in Section 8.2; (iii) other than such dividends and
distributions as the Committee may designate, the Company or its designee will retain custody of
all distributions ("Retained Distributions") made or declared with respect to the Restricted Shares
(and such Retained Distributions will be subject to the same restrictions, terms and vesting, and
other conditions as are applicable to the Restricted Shares) until such time, if ever, as the
Restricted Shares with respect to which such Retained Distributions shall have been made, paid or
declared shall have become vested, and such Retained Distributions shall not bear interest or be
segregated in a separate account; (iv) the Holder may not sell, assign, transfer, pledge, exchange,
encumber or dispose of the Restricted Shares or any Retained Distributions or

-11-

 

his interest in any of them during the Restriction Period; and (v) a breach of any
restrictions, terms or conditions provided in the Plan or established by the Committee with respect
to any Restricted Shares or Retained Distributions will cause a forfeiture of such Restricted
Shares and any Retained Distributions with respect thereto.

     8.4 Issuance of Stock at End of the Restriction Period. Restricted Shares issued at the end
of the Restriction Period shall not constitute issued and outstanding shares of the applicable
series of Common Stock, and the Holder shall not have any of the rights of a stockholder with
respect to the shares of Common Stock covered by such an Award of Restricted Shares, in each case
until such shares shall have been transferred to the Holder at the end of the Restriction Period.
If and to the extent that shares of Common Stock are to be issued at the end of the Restriction
Period, the Holder shall be entitled to receive Dividend Equivalents with respect to the shares of
Common Stock covered thereby either (i) during the Restriction Period or (ii) in accordance with
the rules applicable to Retained Distributions, as the Committee may specify in the Agreement.

     8.5 Cash Payments. In connection with any Award of Restricted Shares, an Agreement may
provide for the payment of a cash amount to the Holder of such Restricted Shares after such
Restricted Shares shall have become vested. Such cash amounts shall be payable in accordance with
such additional restrictions, terms and conditions as shall be prescribed by the Committee in the
Agreement and shall be in addition to any other salary, incentive, bonus or other compensation
payments which such Holder shall be otherwise entitled or eligible to receive from the Company.

     8.6 Completion of Restriction Period. On the Vesting Date with respect to each Award of
Restricted Shares and the satisfaction of any other applicable restrictions, terms and conditions,
(i) all or the applicable portion of such Restricted Shares shall become vested, (ii) any Retained
Distributions and any unpaid Dividend Equivalents with respect to such Restricted Shares shall
become vested to the extent that the Restricted Shares related thereto shall have become vested,
and (iii) any cash amount to be received by the Holder with respect to such Restricted Shares shall
become payable, all in accordance with the terms of the applicable Agreement. Any such Restricted
Shares, Retained Distributions and any unpaid Dividend Equivalents that shall not become vested
shall be forfeited to the Company, and the Holder shall not thereafter have any rights (including
dividend and voting rights) with respect to such Restricted Shares, Retained Distributions and any
unpaid Dividend Equivalents that shall have been so forfeited. The Committee may, in its
discretion, provide that the delivery of any Restricted Shares, Retained Distributions and unpaid
Dividend Equivalents that shall have become vested, and payment of any related cash amounts that
shall have become payable under this Article VIII, shall be deferred until such date or dates as
the recipient may elect. Any election of a recipient pursuant to the preceding sentence shall be
filed in writing with the Committee in accordance with such rules and regulations, including any
deadline for the making of such an election, as the Committee may provide, and shall be made in
compliance with Section 409A of the Code.

ARTICLE IX

Stock Units

     9.1 Grant. In addition to granting Awards of Options, SARs and Restricted Shares, the
Committee shall, subject to the limitations of the Plan, have authority to grant to eligible
persons Awards of Stock Units which may be in the form of shares of any specified series of Common
Stock or units, the value of which is based, in whole or in part, on the Fair Market Value of the
shares of any specified series of Common Stock. Subject to the provisions of the Plan, including
any rules established pursuant to Section 9.2, Awards of Stock Units shall be subject to such
terms, restrictions, conditions, vesting requirements and payment rules as the Committee may
determine in its discretion, which need not be identical for each Award. The determinations made
by the Committee pursuant to this Section 9.1 shall be specified in the applicable Agreement.

     9.2 Rules. The Committee may, in its discretion, establish any or all of the following rules
for application to an Award of Stock Units:

     (a) Any shares of Common Stock which are part of an Award of Stock Units may not be
assigned, sold, transferred, pledged or otherwise encumbered prior to the date on which the
shares are issued or, if later, the date provided by the Committee at the time of the Award.

     (b) Such Awards may provide for the payment of cash consideration by the person to whom
such Award is granted or provide that the Award, and any shares of Common Stock to be issued
in connection therewith, if applicable, shall be delivered without the payment of cash
consideration; provided, however, that the issuance of any shares of Common Stock in
connection with an Award of Stock Units shall be for at least the minimum consideration
necessary to permit such shares to be deemed fully paid and nonassessable.

     (c) Awards of Stock Units may provide for deferred payment schedules, vesting over a
specified period of employment, the payment (on a current or deferred basis) of dividend
equivalent amounts with respect to the number of shares of Common Stock covered by the
Award, and elections by the employee to defer payment of the Award or the lifting of
restrictions on the Award, if any, provided that any such deferrals shall comply with the
requirements of Section 409A of the Code.

     (d) In such circumstances as the Committee may deem advisable, the Committee may waive
or otherwise remove, in whole or in part, any restrictions or limitations to which a Stock
Unit Award was made subject at the time of grant.

ARTICLE X

Cash Awards and Performance Awards

     10.1 Cash Awards. In addition to granting Options, SARs, Restricted Shares and Stock Units,
the Committee shall, subject to the limitations of the Plan, have authority to grant to

-13-

 

eligible persons Cash Awards. Each Cash Award shall be subject to such terms and conditions,
restrictions and contingencies as the Committee shall determine. Restrictions and contingencies
limiting the right to receive a cash payment pursuant to a Cash Award shall be based upon the
achievement of single or multiple Performance Objectives over a performance period established by
the Committee. The determinations made by the Committee pursuant to this Section 10.1 shall be
specified in the applicable Agreement.

     10.2 Designation as a Performance Award. The Committee shall have the right to designate any
Award of Options, SARs, Restricted Shares or Stock Units as a Performance Award. All Cash Awards
shall be designated as Performance Awards.

     10.3 Performance Objectives. The grant or vesting of a Performance Award shall be subject to
the achievement of Performance Objectives over a performance period established by the Committee
based upon one or more of the following business criteria that apply to the Holder, one or more
business units, divisions or Subsidiaries of the Company or the applicable sector of the Company,
or the Company as a whole, and if so desired by the Committee, by comparison with a peer group of
companies: increased revenue; net income measures (including income after capital costs and income
before or after taxes); stock price measures (including growth measures and total stockholder
return); price per share of Common Stock; market share; earnings per share (actual or targeted
growth); earnings before interest, taxes, depreciation, and amortization (EBITDA); economic value
added (or an equivalent metric); market value added; debt to equity ratio; cash flow measures
(including cash flow return on capital, cash flow return on tangible capital, net cash flow and net
cash flow before financing activities); return measures (including return on equity, return on
average assets, return on capital, risk-adjusted return on capital, return on investors’ capital
and return on average equity); operating measures (including operating income, funds from
operations, cash from operations, after-tax operating income; sales volumes, production volumes and
production efficiency); expense measures (including overhead cost and general and administrative
expense); margins; stockholder value; total stockholder return; proceeds from dispositions; total
market value and corporate values measures (including ethics compliance, environmental and safety).
Unless otherwise stated, such a Performance Objective need not be based upon an increase or
positive result under a particular business criterion and could include, for example, maintaining
the status quo or limiting economic losses (measured, in each case, by reference to specific
business criteria). The Committee shall have the authority to determine whether the Performance
Objectives and other terms and conditions of the Award are satisfied, and the Committee’s
determination as to the achievement of Performance Objectives relating to a Performance Award shall
be made in writing.

     10.4 Section 162(m) of the Code. Notwithstanding the foregoing provisions, if the Committee
intends for a Performance Award to be granted and administered in a manner designed to preserve the
deductibility of the compensation resulting from such Award in accordance with Section 162(m) of
the Code, then the Performance Objectives for such particular Performance Award relative to the
particular period of service to which the Performance Objectives relate shall be established by the
Committee in writing (i) no later than 90 days after the beginning of such period and (ii) prior to
the completion of 25% of such period.

-14-

 

     10.5 Waiver of Performance Objectives. The Committee shall have no discretion to modify or
waive the Performance Objectives or conditions to the grant or vesting of a Performance Award
unless such Award is not intended to qualify as qualified performance-based compensation under
Section 162(m) of the Code and the relevant Agreement provides for such discretion.

ARTICLE XI

General Provisions

     11.1 Acceleration of Awards.

     (a) Death or Disability. If a Holder’s employment shall terminate by reason of death
or Disability, notwithstanding any contrary waiting period, installment period, vesting
schedule or Restriction Period in any Agreement or in the Plan, unless the applicable
Agreement provides otherwise: (i) in the case of an Option or SAR, each outstanding Option
or SAR granted under the Plan shall immediately become exercisable in full in respect of the
aggregate number of shares covered thereby; (ii) in the case of Restricted Shares, the
Restriction Period applicable to each such Award of Restricted Shares shall be deemed to
have expired and all such Restricted Shares, any related Retained Distributions and any
unpaid Dividend Equivalents shall become vested and any related cash amounts payable
pursuant to the applicable Agreement shall be adjusted in such manner as may be provided in
the Agreement; and (iii) in the case of Stock Units, each such Award of Stock Units shall
become vested in full.

     (b) Approved Transactions; Board Change; Control Purchase. In the event of any
Approved Transaction, Board Change or Control Purchase, notwithstanding any contrary waiting
period, installment period, vesting schedule or Restriction Period in any Agreement or in
the Plan, unless the applicable Agreement provides otherwise: (i) in the case of an Option
or SAR, each such outstanding Option or SAR granted under the Plan shall become exercisable
in full in respect of the aggregate number of shares covered thereby; (ii) in the case of
Restricted Shares, the Restriction Period applicable to each such Award of Restricted Shares
shall be deemed to have expired and all such Restricted Shares, any related Retained
Distributions and any unpaid Dividend Equivalents shall become vested and any related cash
amounts payable pursuant to the applicable Agreement shall be adjusted in such manner as may
be provided in the Agreement; and (iii) in the case of Stock Units, each such Award of Stock
Units shall become vested in full, in each case effective upon the Board Change or Control
Purchase or immediately prior to consummation of the Approved Transaction. The effect, if
any, on a Cash Award of an Approved Transaction, Board Change or Control Purchase shall be
prescribed in the applicable Agreement. Notwithstanding the foregoing, unless otherwise
provided in the applicable Agreement, the Committee may, in its discretion, determine that
any or all outstanding Awards of any or all types granted pursuant to the Plan will not vest
or become exercisable on an accelerated basis in connection with an Approved Transaction if
effective provision has been made for the taking of such action which, in the opinion of the
Committee, is equitable and appropriate to substitute a new Award for such Award or

-15-

 

to assume such Award and to make such new or assumed Award, as nearly as may be
practicable, equivalent to the old Award (before giving effect to any acceleration of the
vesting or exercisability thereof), taking into account, to the extent applicable, the kind
and amount of securities, cash or other assets into or for which the applicable series of
Common Stock may be changed, converted or exchanged in connection with the Approved
Transaction.

     11.2 Termination of Employment.

     (a) General. If a Holder’s employment shall terminate prior to an Option or SAR
becoming exercisable or being exercised (or deemed exercised, as provided in Section 7.2) in
full, or during the Restriction Period with respect to any Restricted Shares or prior to the
vesting or complete exercise of any Stock Units, then such Option or SAR shall thereafter
become or be exercisable, such Stock Units to the extent vested shall thereafter be
exercisable, and the Holder’s rights to any unvested Restricted Shares, Retained
Distributions, unpaid Dividend Equivalents and related cash amounts and any such unvested
Stock Units shall thereafter vest, in each case solely to the extent provided in the
applicable Agreement; provided, however, that, unless otherwise determined by the Committee
and provided in the applicable Agreement, (i) no Option or SAR may be exercised after the
scheduled expiration date thereof; (ii) if the Holder’s employment terminates by reason of
death or Disability, the Option or SAR shall remain exercisable for a period of at least one
year following such termination (but not later than the scheduled expiration of such Option
or SAR); and (iii) any termination of the Holder‘s employment for cause will be treated in
accordance with the provisions of Section 11.2(b). The effect on a Cash Award of the
termination of a Holder’s employment for any reason, other than for cause, shall be
prescribed in the applicable Agreement.

     (b) Termination for Cause. If a Holder’s employment with the Company or a Subsidiary
of the Company shall be terminated by the Company or such Subsidiary for “cause” during the
Restriction Period with respect to any Restricted Shares or prior to any Option or SAR
becoming exercisable or being exercised in full or prior to the vesting or complete exercise
of any Stock Unit or the payment in full of any Cash Award (for these purposes, “cause”
shall have the meaning ascribed thereto in any employment agreement to which such Holder is
a party or, in the absence thereof, shall include insubordination, dishonesty, incompetence,
moral turpitude, other misconduct of any kind and the refusal to perform his duties and
responsibilities for any reason other than illness or incapacity; provided, however, that if
such termination occurs within 12 months after an Approved Transaction or Control Purchase
or Board Change, termination for “cause” shall mean only a felony conviction for fraud,
misappropriation, or embezzlement), then, unless otherwise determined by the Committee and
provided in the applicable Agreement, (i) all Options and SARs and all unvested or
unexercised Stock Units and all unpaid Cash Awards held by such Holder shall immediately
terminate, and (ii) such Holder’s rights to all Restricted Shares, Retained Distributions,
any unpaid Dividend Equivalents and any related cash amounts shall be forfeited immediately.

-16-

 

     (c) Miscellaneous. The Committee may determine whether any given leave of absence
constitutes a termination of employment; provided, however, that for purposes of the Plan,
(i) a leave of absence, duly authorized in writing by the Company for military service or
sickness, or for any other purpose approved by the Company if the period of such leave does
not exceed 90 days, and (ii) a leave of absence in excess of 90 days, duly authorized in
writing by the Company provided the employee’s right to reemployment is guaranteed either by
statute or contract, shall not be deemed a termination of employment. Unless otherwise
determined by the Committee and provided in the applicable Agreement, Awards made under the
Plan shall not be affected by any change of employment so long as the Holder continues to be
an employee of the Company.

     11.3 Right of Company to Terminate Employment. Nothing contained in the Plan or in any Award,
and no action of the Company or the Committee with respect thereto, shall confer or be construed to
confer on any Holder any right to continue in the employ of the Company or any of its Subsidiaries
or interfere in any way with the right of the Company or any Subsidiary of the Company to terminate
the employment of the Holder at any time, with or without cause, subject, however, to the
provisions of any employment agreement between the Holder and the Company or any Subsidiary of the
Company.

     11.4 Nonalienation of Benefits. Except as set forth herein, no right or benefit under the
Plan shall be subject to anticipation, alienation, sale, assignment, hypothecation, pledge,
exchange, transfer, encumbrance or charge, and any attempt to anticipate, alienate, sell, assign,
hypothecate, pledge, exchange, transfer, encumber or charge the same shall be void. No right or
benefit hereunder shall in any manner be liable for or subject to the debts, contracts, liabilities
or torts of the Person entitled to such benefits.

     11.5 Written Agreement. Each Award of Options shall be evidenced by a stock option agreement;
each Award of SARs shall be evidenced by a stock appreciation rights agreement; each Award of
Restricted Shares shall be evidenced by a restricted shares agreement; each Award of Stock Units
shall be evidenced by a stock units agreement; and each Performance Award shall be evidenced by a
performance award agreement (including a cash award agreement evidencing a Cash Award), each in
such form and containing such terms and provisions not inconsistent with the provisions of the Plan
as the Committee from time to time shall approve; provided, however, that if more than one type of
Award is made to the same Holder, such Awards may be evidenced by a single Agreement with such
Holder. Each grantee of an Option, SAR, Restricted Shares, Stock Units or Performance Award
(including a Cash Award) shall be notified promptly of such grant, and a written Agreement shall be
promptly executed and delivered by the Company. Any such written Agreement may contain (but shall
not be required to contain) such provisions as the Committee deems appropriate (i) to insure that
the penalty provisions of Section 4999 of the Code will not apply to any stock or cash received by
the Holder from the Company or (ii) to provide cash payments to the Holder to mitigate the impact
of such penalty provisions upon the Holder. Any such Agreement may be supplemented or amended from
time to time as approved by the Committee as contemplated by Section 11.7(b).

     11.6 Designation of Beneficiaries. Each person who shall be granted an Award under the Plan
may designate a beneficiary or beneficiaries and may change such designation from
time to time by filing a written designation of beneficiary or beneficiaries with the
Committee on a form to be prescribed by it, provided that no such designation shall be effective
unless so filed prior to the death of such person.

-17-

 

     11.7 Termination and Amendment.

     (a) General. Unless the Plan shall theretofore have been terminated as hereinafter
provided, no Awards may be made under the Plan on or after the tenth anniversary of the
Effective Date. The Plan may be terminated at any time prior to the tenth anniversary of
the Effective Date and may, from time to time, be suspended or discontinued or modified or
amended if such action is deemed advisable by the Committee.

     (b) Modification. No termination, modification or amendment of the Plan may, without
the consent of the person to whom any Award shall theretofore have been granted, adversely
affect the rights of such person with respect to such Award, except as otherwise permitted
by Section 11.18. No modification, extension, renewal or other change in any Award granted
under the Plan shall be made after the grant of such Award, unless the same is consistent
with the provisions of the Plan. With the consent of the Holder, or as otherwise permitted
under Section 11.18, and subject to the terms and conditions of the Plan (including Section
11.7(a)), the Committee may amend outstanding Agreements with any Holder, including any
amendment which would (i) accelerate the time or times at which the Award may be exercised
and/or (ii) extend the scheduled expiration date of the Award. Without limiting the
generality of the foregoing, the Committee may, but solely with the Holder’s consent unless
otherwise provided in the Agreement, agree to cancel any Award under the Plan and grant a
new Award in substitution therefore, provided that the Award so substituted shall satisfy
all of the requirements of the Plan as of the date such new Award is made. Nothing
contained in the foregoing provisions of this Section 11.7(b) shall be construed to prevent
the Committee from providing in any Agreement that the rights of the Holder with respect to
the Award evidenced thereby shall be subject to such rules and regulations as the Committee
may, subject to the express provisions of the Plan, adopt from time to time or impair the
enforceability of any such provision.

     11.8 Government and Other Regulations. The obligation of the Company with respect to Awards
shall be subject to all applicable laws, rules and regulations and such approvals by any
governmental agencies as may be required, including the effectiveness of any registration statement
required under the Securities Act of 1933, and the rules and regulations of any securities exchange
or association on which the Common Stock may be listed or quoted. For so long as any series of
Common Stock are registered under the Exchange Act, the Company shall use its reasonable efforts to
comply with any legal requirements (i) to maintain a registration statement in effect under the
Securities Act of 1933 with respect to all shares of the applicable series of Common Stock that may
be issued to Holders under the Plan and (ii) to file in a timely manner all reports required to be
filed by it under the Exchange Act.

     11.9 Withholding. The Company’s obligation to deliver shares of Common Stock or pay cash in
respect of any Award under the Plan shall be subject to applicable federal, state and local tax
withholding requirements. Federal, state and local withholding tax due at the time of an Award,
upon the exercise of any Option or SAR or upon the vesting of, or expiration of restrictions with
respect to, Restricted Shares or Stock Units or the satisfaction of the

Performance Objectives applicable to a Performance Award, as appropriate, may, in the
discretion of the Committee, be paid in shares of the applicable series of Common Stock already
owned by the Holder or through the withholding of shares otherwise issuable to such Holder, upon
such terms and conditions (including the conditions referenced in Section 6.5) as the Committee
shall determine. If the Holder shall fail to pay, or make arrangements satisfactory to the
Committee for the payment to the Company of, all such federal, state and local taxes required to be
withheld by the Company, then the Company shall, to the extent permitted by law, have the right to
deduct from any payment of any kind otherwise due to such Holder an amount equal to any federal,
state or local taxes of any kind required to be withheld by the Company with respect to such Award.

     11.10 Nonexclusivity of the Plan. The adoption of the Plan by the Board shall not be
construed as creating any limitations on the power of the Board to adopt such other incentive
arrangements as it may deem desirable, including the granting of stock options and the awarding of
stock and cash otherwise than under the Plan, and such arrangements may be either generally
applicable or applicable only in specific cases.

     11.11 Exclusion from Pension and Profit-Sharing Computation. By acceptance of an Award,
unless otherwise provided in the applicable Agreement, each Holder shall be deemed to have agreed
that such Award is special incentive compensation that will not be taken into account, in any
manner, as salary, compensation or bonus in determining the amount of any payment under any
pension, retirement or other employee benefit plan, program or policy of the Company or any
Subsidiary of the Company. In addition, each beneficiary of a deceased Holder shall be deemed to
have agreed that such Award will not affect the amount of any life insurance coverage, if any,
provided by the Company on the life of the Holder which is payable to such beneficiary under any
life insurance plan covering employees of the Company or any Subsidiary of the Company.

     11.12 Unfunded Plan. Neither the Company nor any Subsidiary of the Company shall be required
to segregate any cash or any shares of Common Stock which may at any time be represented by Awards,
and the Plan shall constitute an "unfunded” plan of the Company. Except as provided in Article
VIII with respect to Awards of Restricted Shares and except as expressly set forth in an Agreement,
no employee shall have voting or other rights with respect to the shares of Common Stock covered by
an Award prior to the delivery of such shares. Neither the Company nor any Subsidiary of the
Company shall, by any provisions of the Plan, be deemed to be a trustee of any shares of Common
Stock or any other property, and the liabilities of the Company and any Subsidiary of the Company
to any employee pursuant to the Plan shall be those of a debtor pursuant to such contract
obligations as are created by or pursuant to the Plan, and the rights of any employee, former
employee or beneficiary under the Plan shall be limited to those of a general creditor of the
Company or the applicable Subsidiary of the Company, as the case may be. In its sole discretion,
the Board may authorize the creation of trusts or other arrangements to meet the obligations of the
Company under the Plan, provided, however, that the existence of such trusts or other arrangements
is consistent with the unfunded status of the Plan.

     11.13 Governing Law. The Plan shall be governed by, and construed in accordance with, the
laws of the State of Delaware.

     11.14 Accounts. The delivery of any shares of Common Stock and the payment of any amount in
respect of an Award shall be for the account of the Company or the applicable Subsidiary of the
Company, as the case may be, and any such delivery or payment shall not be made until the recipient
shall have paid or made satisfactory arrangements for the payment of any applicable withholding
taxes as provided in Section 11.9.

     11.15 Legends. Each certificate evidencing shares of Common Stock subject to an Award shall
bear such legends as the Committee deems necessary or appropriate to reflect or refer to any terms,
conditions or restrictions of the Award applicable to such shares, including any to the effect that
the shares represented thereby may not be disposed of unless the Company has received an opinion of
counsel, acceptable to the Company, that such disposition will not violate any federal or state
securities laws.

     11.16 Company’s Rights. The grant of Awards pursuant to the Plan shall not affect in any way
the right or power of the Company to make reclassifications, reorganizations or other changes of or
to its capital or business structure or to merge, consolidate, liquidate, sell or otherwise dispose
of all or any part of its business or assets.

     11.17 Interpretation. The words “include,” “includes,” “included” and “including” to the
extent used in the Plan shall be deemed in each case to be followed by the words “without
limitation.”

     11.18 Section 409A. Notwithstanding anything in this Plan to the contrary, if any Plan
provision or Award under the Plan would result in the imposition of an additional tax under Code
Section 409A and related regulations and United States Department of the Treasury pronouncements
(“Section 409A”), that Plan provision or Award will be reformed to avoid imposition of the
applicable tax and no action taken to comply with Section 409A shall be deemed to adversely affect
the Holder’s rights to an Award or require the consent of the Holder.
