ARTICLE 2

THE SECURITIES

Section 2.01.  Form and Dating. 
The Securities and the Trustee’s certificate of authentication shall be
substantially in the form of Exhibit A, which is a part of this Indenture.  The Securities may have notations, legends
or endorsements required by law, stock exchange rule or usage (provided that
any such notation, legend or endorsement required by usage is in a form
acceptable to the Company).  The Company
shall provide any such notations, legends or endorsements to the Trustee in
writing.  Each Security shall be dated
the date of its authentication.

Section 2.02.  Execution And Authentication. 
The Securities shall be executed on behalf of the Company by its
Chairman of the Board, one of its Vice Chairman, its President, one of its
Senior Vice Presidents or one of its Vice Presidents, under its corporate seal
reproduced thereon and attested by its Secretary or one of its Assistant
Secretaries.  The signature of any of
these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile
signatures of individuals who were at any time the proper Officers of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Securities or did not hold such offices at the date of authentication
of such Securities.

 

7

 

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

The Trustee shall authenticate and deliver
Securities for original issue in an aggregate principal amount of up to
$230,000,000 upon a Company Order without any further action by the
Company.  The aggregate principal amount
of Securities and New Convertible Notes outstanding at any time may not exceed
the amount set forth in the foregoing sentence, except as provided in Section
2.07.

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

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

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

Section 2.04.  Paying Agent to Hold Money and Securities in
Trust.  Except as otherwise provided
herein, prior to or on each due date of payments in respect of any Security,
the Company shall deposit with the Paying Agent a sum of money or securities
sufficient to make such payments when so becoming due.  The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold
in trust for the benefit of Securityholders or the Trustee all money and
securities held by the Paying Agent for the making of payments in respect of
the Securities and shall notify the Trustee of any default by the Company in
making any such payment.  At any time
during the continuance of any such default, the Paying Agent shall, upon the
written request of the Trustee, forthwith pay to the Trustee all money and
securities so held in 

 

8

 

trust.  If the Company, a Subsidiary or an Affiliate
of either of them acts as Paying Agent, it shall segregate the money and
securities held by it as Paying Agent and hold it as a separate trust
fund.  The Company at any time may
require a Paying Agent to pay all money and securities held by it to the
Trustee and to account for any funds and securities disbursed by it.  Upon doing so, the Paying Agent shall have
no further liability for the money or securities.

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

Section 2.06.  Exchange and Registration of Transfer of
Securities; Depositary.  Upon surrender
for registration of transfer of any Security at any office or agency of the
Company designated as Registrar or co-registrar pursuant to Section 2.03 and
satisfaction of the requirements for such transfer set forth in this Section
2.06, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount.

Securities may be exchanged for a like aggregate
principal amount of Securities of other authorized denominations.  Securities to be exchanged shall be
surrendered at any office or agency to be maintained by the Company designated
as Registrar or co-registrar pursuant to Section 2.03 and the Company shall
execute and register and the Trustee shall authenticate and deliver in exchange
therefor the Security or Securities which the Securityholder making the
exchange shall be entitled to receive, bearing registration numbers not
contemporaneously outstanding.

All Securities presented for registration of
transfer or for exchange, purchase, redemption or payment shall (if so required
by the Company, the Trustee, the Registrar or any co-registrar) be duly
endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and the Trustee, duly executed by
the Holder or his attorney duly authorized in writing.

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

 

9

 

None of the Company, the Trustee, the Registrar or
any co-registrar shall be required to exchange or register a transfer of (a)
any Securities for a period of 15 days next preceding any selection of
Securities to be redeemed or (b) any Securities or portions thereof selected or
called for redemption or (c) any Securities or portion thereof surrendered for
redemption (and not withdrawn) pursuant to Section 3.07.

All Securities issued upon any transfer or exchange
of Securities shall be valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture as the Securities
surrendered upon such exchange or transfer.

The provisions of Clauses (a), (b), (c), (d) and (e)
below shall apply only to Global Securities:

(a)       Each Global Security
authenticated under this Indenture shall be registered in the name of the
Depositary designated for such Global Security or a nominee thereof and
delivered to such Depositary or a nominee thereof or Custodian therefor, and
each such Global Security shall constitute a single Security for all purposes
of this Indenture.

(b)      Notwithstanding any other
provision in this Indenture, no Global Security may be exchanged in whole or in
part for Securities registered, and no transfer of a Global Security in whole
or in party may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such
Depositary (i) has notified the Company that it is unwilling or unable to
continue as Depositary for such Global Security or (ii) has ceased to be a
clearing agency registered under the Exchange Act, or (B) there shall have
occurred and be continuing an Event of Default with respect to such Global
Security.

(c)       Subject to 2.06(b)
above, any exchange of a Global Security for other Securities may be made in
whole or in part, and all Securities issued in exchange for a Global Security
or any portion thereof shall be registered in such names as the Depositary for
such Global Security shall direct.

(d)      Every Security
authenticated and delivered upon registration of transfer of, or in exchange
for or in lieu of, a Global Security or any portion thereof whether pursuant to
this Article Two or otherwise, shall be authenticated and delivered in the form
of, and shall be, a Global Security, unless such Security is registered in the
name of a Person other than the Depositary for such Global Security or a
nominee thereof.

 

10

 

(e)       The Depositary or its
nominee, as registered own of a Global Security, shall be the Holder of such
Global Security for all purposes under the Indenture and the Securities, and
owners of beneficial interests in a Global Security shall hold such interests
pursuant to the applicable procedures. 
Accordingly, any such owner’s beneficial interest in a Global Security
will be shown only on, and the transfer of such interest shall be effected only
through, records maintained by the Depositary or its nominee or its agent
members and such owners of beneficial interests in a Global Security will not
be considered the owners or holders thereof.

The Depositary shall be a clearing agency registered
under the Exchange Act.  The Company
initially appoints The Depository Trust Company to act as Depositary with
respect to the Securities in global form. 
Initially, the Global Security shall be issued to the Depositary,
registered in the name of Cede & Co., as the nominee of the Depositary, and
deposited with the Trustee as custodian for Cede & Co.

If at any time the Depositary for the Global
Security notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security, the Company may appoint a successor
Depositary with respect to such Security. 
If a successor Depositary for the Global Security is not appointed by
the Company within 90 days after the Company receives such notice, the Company
will execute, and the Trustee, upon receipt of a Company Order for
authentication and delivery of Securities, will authenticate and deliver,
Securities in definitive form, in an aggregate principal amount equal to the
principal amount of the Global Security, in exchange for such Security in the
global form.

Section 2.07.  Replacement Securities. 
If (i) any mutilated Security is surrendered to the Trustee, or (ii)
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Company or
the Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in
lieu of any such destroyed, lost or stolen Security, a new Security of like
tenor and principal amount, bearing a number not contemporaneously outstanding.

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

 

11

 

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

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

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

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

If a Security is replaced pursuant to Section 2.07,
it ceases to be outstanding unless the Trustee receives proof satisfactory to
it that the replaced Security is held by a bona fide purchaser.

If the Paying Agent holds, in accordance with this
Indenture, on a Redemption Date, on a Fundamental Change Repurchase Date or on
Stated Maturity, money or securities, if permitted hereunder, sufficient to pay
Securities payable on that date, then on and after that date such Securities
shall cease to be outstanding and interest on such Securities shall cease to
accrue; provided, that if such Securities are to be redeemed, notice of such
redemption has been duly given pursuant to this Indenture or provision therefor
satisfactory to the Trustee has been made.

 

12

 

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

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

Section 2.10.  Cancellation. 
All Securities surrendered for payment, redemption or registration of
transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled by it.  The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Securities so delivered shall be promptly canceled by the Trustee.  The Company may not issue new Securities to
replace Securities it has paid or delivered to the Trustee for cancellation.  No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture.  All canceled Securities held by the Trustee shall be destroyed by
the Trustee and evidence of their destruction delivered to the Company unless
the Company directs by Company Order that the Trustee deliver canceled
Securities to the Company.

Section 2.11.  Persons Deemed Owners. 
Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal amount, premium, if
any, interest, Redemption Price and Fundamental Change Redemption Price in
respect thereof, for all purposes whatsoever, whether or not such Security be
overdue, and none of the Company, the Trustee or any agent of the Company or
the Trustee shall be affected by notice to the contrary.

 

13

 

Section 2.12.  Payment of Interest; Interest Rights
Preserved.  Interest on any Security
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest.

Any interest on any Security which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date or
Additional Interest Payment Date (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date
or Additional Interest Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in (a) or (b) below:

(a)       The Company may elect to
make payment of any Defaulted Interest to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest, which shall be fixed in the following manner. The Company shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to
be paid on each Security and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit on or
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the
proposed payment.  The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder at his address as it appears in the
Security Register, not less than 10 days prior to such Special Record
Date.  Notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable pursuant
to the following 2.12(b).

(b)      The Company may make
payment of any Defaulted Interest in any other lawful manner not inconsistent
with the requirements of any 

 

14

 

securities exchange or market on which the Securities may be listed, and upon
such notice as may be required by such exchange or market, if, after notice
given by the Company to the Trustee of the proposed payment pursuant to this
Clause, such manner of payment shall be deemed practicable by the Trustee.

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

Section 2.13.  Computation of Interest. 
Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

Section 2.14.  Preservation of Information; Communications
to Holders.

(a)   The Trustee shall preserve, in as current a
form as is reasonably practicable, the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 2.05
and the names and addresses of Holders received by the Trustee in its capacity
as Security Registrar.  The Trustee may
destroy any list furnished to it as provided in Section 2.05 upon receipt of a
new list so furnished.

(b)   The rights of Holders to communicate with
other Holders with respect to their rights under this Indenture or under the
Securities, and the corresponding right and duties of the Trustee, shall be as
provided in the TIA.

(c)   Every Holder of Securities, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of the disclosure of information as to names and
addresses of the Holders made pursuant to the TIA.

Section 2.15.  Additional Interest Payment Obligation. 
Interest payable on any Security shall be increased in the
circumstances described under Section 10.13(c) and (d) below:

(a)   The Company shall maintain EBITDA (as defined
herein) of not less than (i) $0.00  for
the fiscal quarters ending on December 26, 2003 and June 25, 2004, and
(ii) ($5,000,000) for the fiscal quarters ending on March 26, 2004 and
September 24, 2004.  “EBITDA” shall be
defined for purposes of this Section 2.15 as the Company’s consolidated net
earnings (or loss), plus net interest expense, income taxes, depreciation and
amortization for the relevant fiscal quarter, as determined in accordance with
GAAP and as reported by the Company in the cash flow statement included in its
quarterly report on Form 10-Q 

 

15

 

filed with the SEC relating
to such fiscal quarter.  All non-cash
restructuring charges and any extraordinary losses for the applicable fiscal
quarter shall be eliminated in the calculation of EBITDA for purposes of
determining compliance with this condition.

(b)   The Company shall, on or prior to December
31, 2003, reduce the aggregate principal amount of Securities and New
Convertible Notes (together, the “2009 Notes”) outstanding on the date hereof
by $25 million; provided that any purchases by the Company of up to $10 million
principal amount of Old Notes at a price (including commissions and other costs
of sale) equal to 85% or less of their principal amount shall be deemed a
reduction by an equal dollar amount of the outstanding principal amount of 2009
Notes. The Company may satisfy this obligation through open market or private
purchases or by initiating a cash tender offer at par (plus accrued interest)
for 2009 Notes and accepting and paying for sufficient New 2009 to satisfy this
condition.  In the event that less than
the aggregate principal amount of 2009 Notes required to satisfy this condition
are tendered, the Company’s acceptance of and payment for any and all 2009
Notes validly tendered will fully satisfy its obligations under this paragraph.

(c)   If the Company shall not have satisfied the
condition set forth in Section 2.15 (a) above in any fiscal quarter to which
such condition applies, the interest payable on the Securities shall increase
to a rate per annum equal to 14.75% for such fiscal quarter.

(d)   If the Company shall have satisfied the
condition set forth in Section 2.15(a) above in any fiscal quarter to which
such condition applies, but the Company has not reduced the outstanding
principal amount of 2009 Notes as required by Section 2.15(b), then the
interest payable on the Securities shall be increased to a rate per annum equal
to 14.75%; provided that if the Company shall have satisfied the condition set
forth in Section 2.15(b) in part, then the interest payable on the Securities
shall be increased (i) to a rate per annum equal to 13.75% if the outstanding
principal amount of 2009 Notes has been reduced (or deemed reduced) by at least
$10 million and less than $17.5 million and (ii) to a rate per annum equal to
12.75% if the outstanding principal amount of 2009 Notes has been reduced (or
deemed reduced) by at least $17.5 million and less than $25 million.

(e)   In the event that Sections 2.15(c) or (d)
require an increase in the interest payable on the Securities with respect to
any fiscal quarter (an “Additional Interest Payment”), the Company shall make
the Additional Interest Payment to the Persons in whose names the Securities
(or their respective Predecessor Securities) are registered at the close of business
on an Additional Interest Record Date for the Additional Interest Payment,
which shall be fixed in the following manner. 
The Company shall notify the Trustee in writing of the amount of the
Additional Interest Payment to be paid on each Security and the 

 

16

 

date such payment is to be
made (the “Additional Interest Payment Date”), and at the same time the Company
shall deposit with the Trustee an amount of money equal to the aggregate
Additional Interest Payment to be made or shall make arrangements satisfactory
to the Trustee for such deposit on or prior to the Additional Interest Payment
Date, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Additional Interest Payment .  Thereupon the Trustee shall fix a Additional
Interest Record Date for the Additional Interest Payment which shall not be
more than 15 days nor less than 10 days prior to the Additional Interest Payment
Date and not less than 10 days prior to the receipt by the Trustee of the
notice of the Additional Interest Payment. 
The Trustee shall promptly notify the Company of such Additional
Interest Record Date and, in the name of 
and the expense of the Company, shall cause notice of the Additional
Interest Payment to be mailed, first class postage pre-paid, to each Holder at
his address as it appears in the Security Register, not less than 10 days prior
to the Additional Interest Record Date. 
Notice of such Additional Interest Payment having been so mailed, such
Additional Interest Payment shall be paid to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on such Additional Interest Payment Date.  The making of an Additional Interest Payment
shall be the sole and exclusive remedy for the failure of the Company to
satisfy the conditions set forth in Section 2.15(a) and (b) above.

Section 2.16.  Company’s Use of Proceeds from Sale of
Certain Assets.  (a) Until the Company has
complied in full with its obligation set forth in Section 2.15(b) above, it
agrees that it will apply at least 50% of its net cash proceeds from the sale
of (i) businesses, (ii) material fixed assets or patents (other than in
connection with a commercial transaction in which the patents are related to
the subject matter of the transaction) and (iii) its or its Affiliates’ equity
securities to satisfy such obligation; provided, however that amounts from such
sales will be applied first as required by the terms of the Company’s Secured
Credit Facility and thereafter to the satisfaction of its obligation set forth
in Section 2.15(b).  For purposes of
this Section 2.16, “net cash proceeds” shall be defined as to any sale
transaction, as an amount equal to (i) the aggregate amount received in cash
(including any cash received by way of deferred payment pursuant to a note
receivable, installment receivable, purchase price adjustment receivable or
otherwise, but only as and when such cash received) from such sales
transaction, less (ii) the reasonable out-of-pocket expenses and fees incurred
in connection with such sale.

(b)   Upon consummation of a sale transaction
described in Section 2.16(a) above, the Company shall provide the Trustee a
certificate signed by its Chief Financial Officer setting forth (i) a
calculation of the net cash proceeds, including an itemization of fees and
expenses and (ii) certifying, in accordance with the provisions of Section
10.05, that the Company has complied with its obligations under Section 2.16
with respect to the application of such proceeds.

 

17

 

Section 2.17.  Right of Holders of 2009 Notes To Appoint
Directors.  (a) The Company agrees that
it will, as soon as reasonably practicable after submission to the Corporate
Secretary of a written request executed by the Holders of a majority in
principal amount of the 2009 Notes setting forth the names of two nominees to
serve on the Board of Directors, appoint such nominees, provided that such
nominees are reasonably acceptable to the nominating committee of the Board of
Directors.  The Company will include
such nominees in the slate of candidates for the Board of Directors who have
been nominated for terms of  at least
two years at the next annual meeting of shareholders.  In addition, for any period in which the Company is required to
pay Additional Interest, the Holders of a majority in principal amount of the
2009 Notes shall be entitled to name a third member of the Board of Directors who
is reasonably acceptable to the Board’s nominating committee in accordance with
the procedures set forth above.  The
term of such director shall end automatically, and such director shall promptly
submit his or her resignation from the Board of Directors, when the Company is
no longer required to make an Additional Interest Capital Payment.

(b)   In the event of a vacancy on the Board of
Directors created by the death or resignation of a director appointed by the
Holders of the 2009 Notes pursuant to Section 2.17(a) above (other than an
automatic resignation resulting from the termination of the Company’s
requirement to make an Additional Interest Payment), such vacancy may be
filled, after consultation with the Holders of the 2009 Notes, by the remaining
directors or director named by the Holders of the 2009 Notes, provided that
such replacement director is reasonably acceptable to the nominating committee
of the Board of Directors.

ARTICLE 3

REDEMPTION

Section 3.01.  Right to Redeem; Notices to Trustee. 
The Company, at its option, may redeem the Securities in accordance
with the provisions of paragraph 5 of the Securities.  If the Company elects to redeem Securities pursuant to paragraph
5 of the Securities, it shall notify the Trustee in writing of the Redemption
Date, the principal amount of Securities to be redeemed, the Redemption Price,
and the amount of accrued interest to, but excluding, the Redemption Date.

The Company shall give the notice to the Trustee
provided for in this Section 3.01 (i) in the case of any redemption of fewer
than all of the Securities, at least 45 days before the Redemption Date and
(ii) in the case of a redemption of all of the Securities, no later than the
Company is required to give notice to the 

 

18

 

Holders pursuant to Section
3.03, in each case unless a shorter notice shall be satisfactory to the
Trustee.

Section 3.02.  Selection of Securities to be Redeemed. 
If less than all the Securities are to be redeemed, the Trustee shall
select the Securities to be redeemed pro rata or by lot or by a method the
Trustee considers fair and appropriate (as long as such method is not
prohibited by the rules of any stock exchange or automated quotation system on
which the Securities are then listed). 
The Trustee shall make the selection at least 10 days, but not more than
60 days, before the Redemption Date from outstanding Securities not previously
called for redemption.  The Trustee may
select for redemption portions of the principal amount of Securities that have
denominations larger than $1,000. 
Securities and portions of Securities selected by the Trustee shall be
in principal amounts of $1,000 or a multiple of $1,000.  Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called
for redemption.  The Trustee shall
notify the Company promptly of the Securities or portions of Securities to be
redeemed.

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

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

(a)       the Redemption Date;

(b)      the Redemption Price,
together with the amount of accrued interest to, but excluding, the Redemption
Date;

(c)       the name and address of
the Paying Agent;

(d)      that Securities called
for redemption must be surrendered to the Paying Agent to collect the Redemption
Price and accrued interest to, but excluding, the Redemption Date;

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

(f)       that interest on
Securities called for redemption will cease to accrue on and after the
Redemption Date.

At the Company’s request, the Trustee shall give the
notice of redemption in the Company’s name and at the Company’s expense.

 

19

 

Section 3.04.  Effect of Notice of Redemption. 
Once notice of redemption is given, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price,
together with accrued interest to, but excluding, the Redemption Date, stated
in the notice.

Upon the later of the Redemption Date or the date
such Securities are surrendered to the Paying Agent, such Securities shall be
paid at the Redemption Price, together with accrued interest to, but excluding,
the Redemption Date, stated in the notice.

Section 3.05.  Deposit of Redemption Price. 
Prior to or on the Redemption Date, the Company shall deposit with the
Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of
them is the Paying Agent, shall segregate and hold in trust) money sufficient
to pay the Redemption Price and accrued interest to, but excluding, the
Redemption Date of all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which prior thereto
have been delivered by the Company to the Trustee for cancellation; provided
that if such payment is made on the Redemption Date it must be received by the
Trustee or Paying Agent, as the case may be, by 10:00 a.m.  New York City time, on such Redemption
Date.  If such money is then held by the
Company in trust and is not required for such purpose it shall be discharged
from such trust.

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

Section 3.07.  Redemption at Option of the Holder upon a
Fundamental Change.

(a)   If a Fundamental Change shall occur at any
time prior to July 1, 2009, each Holder of Securities shall have the right, at
such Holder’s option, to require the Company to redeem such Holder’s Securities
on the date (the “Fundamental Change Repurchase Date”) (or if
such date is not a Business Day, the next succeeding Business Day) that is 45
days after the date of the Company’s notice of such Fundamental Change.  The Securities will be redeemable in part in
multiples of $1,000 of principal amount. 
Such repayment shall be made at 100% of the principal amount (the “Fundamental
Change Redemption Price”) thereof. In each case, the Company shall
also pay to such Holders accrued interest to, but excluding, the Fundamental Change
Repurchase Date on the redeemed Securities; provided that if such Fundamental
Change Repurchase Date is an Interest Payment Date, then the interest payable
on such 

 

20

 

date shall be paid to the
Holder of the Security on the next preceding the Regular Record Date.

(b)   On or before the tenth day after the
occurrence of a Fundamental Change, the Company, or, at its written request
(which must be received by the Trustee at least five Business Days prior to the
date the Trustee is requested to give notice as described below), the Trustee
in the name of and at the expense of the Company, shall mail or cause to be
mailed to all Holders of record on the date of the Fundamental Change a notice
(the “Company
Notice”) of the occurrence of such Fundamental Change and of the
redemption right at the option of the Holders arising as a result thereof.  Such notice shall be mailed in the manner
and with the effect set forth in Section 3.03. 
The Company shall also deliver a copy of the Company Notice to the
Trustee at such time as it is mailed to the Holders.

Each Company Notice shall specify the circumstances
constituting the Fundamental Change, the Fundamental Change Repurchase Date,
the Fundamental Change Redemption Price at which the Company shall be obligated
to redeem the Securities, the amount of interest accrued on each Security to,
but excluding, the Fundamental Change Repurchase Date, the latest time by which
the Holder must exercise the redemption right (the “Fundamental Change Expiration Time”),
that the Holder shall have the right to withdraw any Notes prior to the
Fundamental Change Expiration Time, a description of the procedure which a
Holder must follow to exercise such redemption right and to withdraw any surrendered
Notes and the place or places where the Holder is to surrender such Holder’s
Securities.

No failure of the Company to give the foregoing
notices and no defect therein shall limit the Holders’ redemption rights or
affect the validity of the proceedings for the repurchase of the Securities
pursuant to this Section 3.07.

(c)   For a Security to be so redeemed at the
option of the Holder, the Paying Agent must receive such Security with the form
entitled “Option to Elect Redemption Upon a Fundamental Change” on the reverse
thereof duly completed (a “Fundamental Change Redemption Notice”),
together with such Security duly endorsed for transfer, on or before the 30th
day after the date of such Company Notice (or if such 30th day is not a
Business Day, the immediately preceding Business Day).  All questions as to the validity,
eligibility (including time of receipt) and acceptance of any Security for
redemption shall be determined by the Company, whose determination shall be
final and binding.

(d)   Upon receipt by the Company of the
Fundamental Change Redemption Notice specified in Section 3.07(c), the Holder
of the Security in respect of which such Fundamental Change Redemption Notice
was given shall (unless such Fundamental Change Redemption Notice is withdrawn
as specified in the following two paragraphs) thereafter be entitled to receive
solely the 

 

21

 

Fundamental Change
Redemption Price, together with accrued interest to, but excluding, the
Fundamental Change Repurchase Date, with respect to such Security.  Such Fundamental Change Redemption Price
together with accrued interest to, but excluding, the Fundamental Change
Repurchase Date, shall be paid to such Holder promptly following the
Fundamental Change Repurchase Date.

A Fundamental Change Redemption Notice may be
withdrawn by the Holder by means of a written notice of withdrawal delivered to
the office of the Paying Agent at any time prior to the close of business on
the Fundamental Change Repurchase Date to which it relates specifying:

(i)    the certificate number of
the Security in respect of which such notice of withdrawal is being submitted,

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

(iii)  the principal amount, if
any, of such Security which remains subject to the original Fundamental Change
Redemption Notice and which has been or will be delivered for purchase by the
Company.

There shall be no redemption pursuant to Section
3.07 if there has occurred prior to, on or after, as the case may be, the
giving, by the Holders of such Securities, of the required Fundamental Change
Redemption Notice and is continuing an Event of Default (other than a default
in the payment of the Fundamental Change Redemption Price, together with
accrued interest to, but excluding, the Fundamental Change Repurchase Date,
with respect to such Securities).

(e)   On or before the Fundamental Change
Repurchase Date the Company shall deposit with the Trustee or with the Paying
Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is
acting as the Paying Agent, shall segregate and hold in trust as provided in
Section 2.04) an amount of money and/or securities, if permitted hereunder,
sufficient to pay the aggregate Fundamental Change Redemption Price, together
with accrued interest to, but excluding, the Fundamental Change Repurchase
Date, of all the Securities or portions thereof which are to be redeemed as of
such Fundamental Change Repurchase Date; provided that if such payment is made
on the Fundamental Change Repurchase Date it must be received by the Trustee or
Paying Agent, as the case may be, by 10:00 a.m.  New York City time, on such Fundamental Change Repurchase Date.

(f)    Any Security that is to be redeemed upon a
Fundamental Change only in part shall be surrendered at the office of the
Paying Agent (with, if the 

 

22

 

Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder’s attorney duly authorized in writing) and the Company
shall execute and, upon the Company’s written direction to the Trustee, the Trustee
shall authenticate and deliver to the Holder of such Security, without service
charge, a new Security or Securities, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in
exchange for, the portion of the principal amount of the Security so
surrendered which is not redeemed.

(g)   In connection with any offer to redeem
Securities under Section 3.07 hereof the Company shall comply with all Federal
and state securities laws so as to permit the rights and obligations under
Section 3.07 to be exercised in the time and in the manner specified in Section
3.07.

(h)   The Trustee and the Paying Agent shall return
to the Company any cash that remains unclaimed as provided in paragraph 9 of
the Securities, together with interest or dividends, if any (subject to the
provisions of Section 7.01(f)), thereon, held by them for the payment of a
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date; provided, however that to
the extent that the aggregate amount of cash deposited by the Company pursuant
to Section 3.07 exceeds the aggregate Fundamental Change Redemption Price,
together with accrued interest to, but excluding, the Fundamental Change Repurchase
Date, of the Securities or portions thereof which the Company is obligated to
purchase as of the Fundamental Change Repurchase Date then promptly after the
Business Day following the Fundamental Change Repurchase Date the Trustee and
the Paying Agent shall return any such excess to the Company together with
interest or dividends, if any, thereon.

purposes and shall give prompt written notice to the Trustee of the location,
and any change in the location, of such other office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and

Section 10.02.

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

 

24

 

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

Securities or New Convertible Notes will remain outstanding, the Stated
Maturity of the indebtedness incurred must be at least 120 days after the

(a)       the Person (if other
than the Company) formed by such consolidation or into which the Company is

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.01.  Events of Default. 
“Event
of Default” occurs if:

(a)   the Company defaults in the payment of the
principal amount of, premium, if any, Redemption Price or Fundamental Change
Redemption Price on any Security when the same becomes due and payable at its
Stated Maturity, upon redemption, upon declaration or otherwise;

(b)   the Company defaults in the payment of any
installment of interest, including an Additional Interest Payment upon any of
the Securities as and when the same shall become due and payable, and
continuance of such default for 30 days;

 

27

 

(c)   the Company fails to comply with any of its
agreements in the Securities or this Indenture (other than those referred to in
clause (a) or (b) above and those set forth in Section 2.15(a) and (b) hereof,
as to which the exclusive remedy is set forth in Section 2.15) and such failure
continues for 60 days after receipt by the Company of a Notice of Default;

(d)   a decree or order by a court having
jurisdiction in the premises shall have been entered adjudging the Company a
bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization of the Company under any Bankruptcy Law, and such decree or
order shall have continued undischarged and unstayed for a period of 60
consecutive days; or a decree or order of a court having jurisdiction in the
premises of the appointment of a receiver or liquidator or trustee or assignee
in bankruptcy or insolvency of the Company or of its property, or for the
winding-up or liquidation of its affairs, shall have been entered, and such
decree or order shall have remained in force undischarged and unstayed of a
period of 60 consecutive days; or

(e)   the Company shall institute proceedings to be
adjudicated a voluntary bankrupt, or shall consent to the filing of a
bankruptcy proceeding against it, or shall file a petition or answer or consent
seeking reorganization under any Bankruptcy Law, or shall consent to the filing
of any such petition, or shall consent to the appointment of a receiver or
liquidator or trustee or assignee in bankruptcy or insolvency of it or of its
property or shall make an assignment for the benefit of creditors, or shall
admit in writing its inability to pay its debts generally as they become due.

(f)    an event of default under the Secured Credit
Facility, the Old Notes Indenture or the New Convertible Indenture shall have
occurred which results in the principal amount and accrued interest on that
debt becoming immediately due and payable.

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

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

Section 6.02.  Acceleration. 
If an Event of Default (other than an Event of Default specified in
Section 6.01(d) or (e)) occurs and is continuing, the Trustee 

 

28

 

by
notice to the Company, or the Holders of at least 25% in aggregate principal
amount of the Securities at the time outstanding by notice to the Company and
the Trustee, may declare the principal amount and premium, if any, on all the
Securities and the interest accrued thereon to be immediately due and
payable.  Upon such a declaration, such
principal amount, premium, if any, and interest accrued thereon shall be due
and payable immediately.  If an Event of
Default specified in Section 6.01(d) or (e) occurs and is continuing, the
principal amount and premium, if any, on all the Securities and the interest
accrued thereon shall become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any
Securityholders.  The Holders of a
majority in aggregate principal amount of the Securities at the time
outstanding, by notice to the Trustee (and without notice to any other
Securityholder) may rescind an acceleration and its consequences if the rescission
would not conflict with any judgment or decree and if all existing Events of
Default have been cured or waived except nonpayment of the principal amount,
premium, if any, and interest accrued thereon that has become due solely as a
result of acceleration and if all amounts due to the Trustee under Section 7.07
have been paid.  No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

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

The Trustee may maintain a proceeding even if the
Trustee does not possess any of the Securities or does not produce any of the
Securities in the proceeding.  A delay
or omission by the Trustee or any Securityholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of, or acquiescence in, the Event of Default.  No remedy is exclusive of any other
remedy.  All available remedies are
cumulative.

Section 6.04.  Waiver of Past Defaults. 
The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding, by notice to the Trustee (and without
notice to any other Securityholder), may waive an existing Default and its
consequences except (1) an Event of Default described in Section 6.01(a)  or 6.01(b), or (2) a Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder affected.  When a Default
is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right.

Section 6.05.  Control by Majority. 
The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding may direct 

 

29

 

the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture or that the Trustee
determines in good faith is unduly prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability unless the
Trustee is offered indemnity satisfactory to it.

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

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

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

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

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

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

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

Section 6.07.  Rights of Holders to Receive Payment. 
Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of the principal amount, premium, if any, accrued
interest, Redemption Price or Fundamental Change Redemption Price in respect of
the Securities held by such Holder, on or after the respective due dates
expressed in the Securities or any Redemption Date or Fundamental Change
Repurchase Date, as the case may be, or to bring suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or
affected adversely without the consent of each such Holder.

Section 6.08.  Collection Suit by Trustee. 
If an Event of Default described in Section 6.01(a) or 6.01(b) occurs
and is continuing, the Trustee may recover 

 

30

 

judgment
in its own name and as trustee of an express trust against the Company for the
whole amount owing with respect to the Securities and the amounts provided for
in Section 7.07.

Section 6.09.  Trustee May File Proofs of Claim. 
In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal amount, premium,
if any, accrued interest, Redemption Price or Fundamental Change Redemption
Price in respect of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment of any such
amount) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

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

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

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

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

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

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

 

31

 

Second:  to Securityholders for amounts due and unpaid on the Securities
for the principal amount, premium, if any, accrued interest, Redemption Price
or Fundamental Change Redemption Price, as the case may be, ratably, without
preference or priority of any kind, according to such amounts due and payable
on the Securities; and

Third:  the balance, if any, to the Company.

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

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

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

ARTICLE 7

TRUSTEE

Section 7.01.  Duties of Trustee. 
(a)  If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in its
exercise as a prudent 

 

32

 

man
would exercise or use under the circumstances in the conduct of his own
affairs.

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

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

(ii)   in the absence of bad faith
on its part, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the
requirements of this Indenture. However, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the
requirements of this Indenture.

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

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

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

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

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

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

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

Section 7.02.  Rights of Trustee. 
(a) The Trustee may rely on any document believed by it to be genuine
and to have been signed or presented by the proper person.  The Trustee need not investigate any fact or
matter stated in the document.

 

33

 

(b)   Before the Trustee acts or refrains from
acting, it may require a Company Order, an Officers’ Certificate or an Opinion
of Counsel.  The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Company Order, Officers’ Certificate or Opinion of Counsel.

(c)   The Trustee may act through agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

(d)   Subject to the provisions of Section 7.01(c),
the Trustee shall not be liable for any action it takes or omits to take in
good faith which it believes to be authorized or within its rights or powers.

Section 7.03.  Individual Rights of Trustee. 
The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee.  Any Paying Agent, Registrar or co-registrar
may do the same with the like rights. 
However, the Trustee must comply with Section 7.10.

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

Section 7.05.  Notice of Defaults. 
If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall give to each Securityholder notice of the Default
within 90 days after it occurs.  Except
in the case of a Default described in Section 6.01(a) or 6.01(b), the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interests of
Securityholders.  The Trustee shall not
give notice of a Default pursuant to Section 6.01(c) until at least sixty (60)
days have passed since its occurrence.

Section 7.06.  Disqualification; Conflicting Interests. 
If the Trustee has or shall acquire any conflicting interest within the
meaning of the TIA, it shall either eliminate such conflicting interest or
resign, to the extent and in the. 
manner provided by, and subject to the provisions of the TIA and this
Indenture.

Section 7.07.  Compensation and Indemnity. 
The Company agrees:

(a)       to pay to the Trustee
from time to time reasonable compensation for all services rendered by it
hereunder (which 

 

34

 

compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust);

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

(c)       to indemnify the Trustee
for, and to hold it harmless against, any loss, liability or expense incurred
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this trust, including the costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.

To secure the Company’s payment obligations in this
Section 7.07, the Trustee shall have a lien prior to the Securities on all
money or property held or collected by the Trustee, except that held in trust
to pay the principal amount, premium, if any, accrued interest, Redemption
Price or Fundamental Change Redemption Price, as the case may be, on particular
Securities.

The Company’s payment obligations pursuant to this
Section 7.07 shall survive the discharge of this Indenture.  When the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01(d)or (e), the expenses are
intended to constitute expenses of administration under any Bankruptcy Law.

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

(a)       the Trustee fails to
comply with, or ceases to be eligible under, Section 7.10;

(b)      the Trustee is adjudged
bankrupt or insolvent;

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

(d)      the Trustee otherwise
becomes incapable of acting.

 

35

 

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

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

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

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

Section 7.09.  Successor Trustee by Merger. 
If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all its corporate trustee business or assets  (including the administration of the trust
created by this Indenture) to, another corporation, the resulting, surviving or
transferee corporation without any further act shall be the successor Trustee.

Section 7.10.  Eligibility; Disqualification. 
The Trustee (or if a Trustee is a member of a bank holding company, its
bank holding company) shall have a combined capital and surplus of at least
$50,000,000 as set forth in its most recent published annual report of
conditions.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section,
it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

Section 7.11.  Preferential Collection of Claims Against
Company.  If and when the Trustee
shall be or become a creditor of the Company (or any other obligor upon the
Securities), the Trustee shall be subject to the provisions of the TIA
regarding the collection of claims against the Company (or any such other
obligor).

Section 7.12.  Reports by Trustee.

 

36

 

(a)   The Trustee shall transmit to Holders such
reports concerning the Trustee and its actions under this Indenture as may be
required pursuant to the TIA at the times and in the manner provided pursuant
thereto.

(b)   A copy of each such report shall, at the time
of such transmission to Holders, be filed by the Trustee with each stock
exchange or market upon which the Securities are listed, with the Commission
and with the Company.  The Company will
notify the Trustee when the Securities are listed on any stock exchange or
market.

ARTICLE 8

DISCHARGE OF INDENTURE

Section 8.01.  Discharge of Liability on Securities. 
When (i) the Company delivers to the Trustee all outstanding Securities
(other than Securities replaced pursuant to Section 2.07) for cancellation or
(ii) all outstanding Securities have become due and payable and the Company
deposits with the Trustee cash and/or securities, as permitted by the terms
hereof, sufficient to pay at Stated Maturity the principal amount of all
outstanding Securities (other than Securities replaced pursuant to Section
2.07), and if in either case the Company pays all other sums payable hereunder
by the Company, then this Indenture shall, subject to Section 7.07, cease to be
of further effect.  The Trustee shall
join in the execution of a document prepared by the Company acknowledging
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers’ Certificate and Opinion of Counsel and at the cost
and expense of the Company.

Section 8.02.  Repayment to the Company. 
The Trustee and the Paying Agent shall return to the Company upon
written request any money or securities held by them for the payment of any amount
with respect to the Securities that remains unclaimed for two years, provided,
however, that the Trustee or such Paying Agent, before being required to make
any such return, shall at the expense of the Company cause to be published once
in a newspaper of general circulation in The City of New York or mail to each
such Holder notice that such money or securities remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication or mailing, any unclaimed money or securities then
remaining will be returned to the Company. 
After return to the Company, Holders entitled to the money or securities
must look to the Company for payment as general creditors unless an applicable
abandoned property law designates another person.

 

37

 

ARTICLE 9

AMENDMENTS

Section 9.01.  Without Consent of Holders. 
The Company and the Trustee may amend this Indenture or the Securities
without the consent of any Securityholder:

(a)       to cure any ambiguity,
defect or inconsistency;

(b)      to comply with Article 5;

(c)       to provide for
uncertificated Securities in addition to certificated Securities so long as
such uncertificated Securities are in registered form for purposes of the

(d)      to make any change that
does not adversely affect the right of any Securityholder; or

(e)       to make any change to
comply with the TIA, or any amendment thereto, or to comply with any
requirement of the SEC in connection with the qualification, if any, of the
Indenture under the TIA.

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

manner or rate of accrual in connection with interest, reduce the rate of
interest referred to in paragraph 1 of the Securities or extend the time for
payment of interest on any Security;

(b)      reduce the Redemption
Price or extend the Stated Maturity;

Price or Fundamental Change Redemption Price of any Security;

(d)      make any Security payable
in money or securities other than that stated in the Security;

(e)       make any change in
Section 6.04, Section 6.07 or this Section 9.02, except to increase any such
percentage; or

 

38

 

(f)       make any change that
adversely affects the right to require the Company to redeem the Securities
upon a Fundamental Change in accordance with the terms thereof and this
Indenture;

and no such amendment or
supplement to this Indenture may reduce the aforesaid percentage of Securities
whose Holders must consent to any such amendment or supplemental indenture,
without the consent of the Holders of all the Securities then outstanding.

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

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

Section 9.03.  Compliance with TIA. 
Every supplemental indenture executed pursuant to this Article shall
comply with the TIA as then in effect.

Section 9.04.  Revocation and Effect of Consents, Waivers

supplemental indenture, waiver or other action becomes effective, a consent to
it or any other action by a Holder of a Security hereunder is a continuing consent
by the Holder and every subsequent Holder of that Security or portion of the
Security that evidences the same obligation as the consenting Holder’s
Security, even if notation of the consent, waiver or action is not made on the
Security.  However, any such Holder or
subsequent Holder may revoke the consent, waiver or action as to such Holder’s
Security or portion of the Security if the Trustee receives the notice or
revocation before the date the amendment, supplemental indenture, waiver or
action becomes effective.  After an
amendment, supplemental indenture, waiver or action becomes effective, it shall
bind every Securityholder.

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

Section 9.06.  Trustee to Sign Supplemental Indentures. 
The Trustee shall sign any supplemental indenture authorized pursuant
to this Article 9 if the amendment does not adversely affect the rights,
duties, liabilities or immunities of 

 

39

 

the
Trustee.  If it does, the Trustee may,
but need not, sign such supplemental indenture.  In signing such supplemental indenture the Trustee shall be
entitled to receive, and (subject to the provisions of Section 7.01) shall be
fully protected in relying upon, an Officers’ Certificate and an Opinion of
Counsel stating that such supplemental indenture is authorized or permitted by
this Indenture.

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

Silicon Graphics, Inc., a Delaware corporation,
promises to pay to or registered assigns, the principal amount of_____________
Dollars ($) on July 1, 2009 and to pay interest thereon from  [the date after expiration of the exchange
offer], 2003 or from the most recent Interest Payment Date to which interest
has been paid or duly provided for, semi-annually on January 1 and July 1 in

not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any securities

[FORM OF REVERSE SIDE OF
SECURITY]

SILICON GRAPHICS, INC.

11.75% SENIOR NOTE DUE 2009

1.             Interest

This Security shall bear interest at 11.75% per
annum (or, in certain circumstances set forth in Section 2.15 of the Indenture
at a higher rate for a specific fiscal quarter as described in such Section
2.15 of the Indenture) in the manner set forth in the Indenture and the face of
this Security.  In the event that
principal hereof or any portion of such principal is not paid when due (whether
upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set
for payment of the Redemption Price pursuant to paragraph 5 hereof, upon the
date set for payment of a Fundamental Change Redemption Price pursuant to
paragraph 6 hereof or upon the Stated Maturity of this Security), then in each
such case the overdue amount shall bear interest at the rate of 11.75% per
annum (or at such rate as may be applicable at the time under Section 2.15 of
the Indenture), compounded semiannually (to the extent that the payment of such
interest shall be legally enforceable), which interest shall accrue from the
date such overdue amount was due to the date payment of such amount, including
interest thereon, has been made or duly provided for.  All such interest shall be payable on demand.

2.             Method of Payment

Subject to the terms and conditions of the
Indenture, the Company will make payments in respect of the Securities to the
persons who are registered Holders of Securities at the close of business on
the Redemption Date, Fundamental Change Repurchase Date or Stated Maturity, as
the case may be.  Holders must surrender
Securities to a Paying Agent to collect such payments in respect of the
Securities.  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.  However, the Company may make such cash payments by check mailed
to the address of, or by wire transfer to the account of, the person entitled
to such payment.

3.             Paying Agent and
Registrar

Initially, U.S. Bank National Association, a
national banking association (the “Trustee”), will act as Paying Agent and
Registrar.  The Company may appoint and
change any Paying Agent, Registrar or co-registrar without notice, 

 

A-4

 

other than notice to the
Trustee.  The Company or any of its
Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion
Agent, Registrar or co-registrar.

4.             Indenture

The Company issued the Securities under an Indenture
dated as of July    , 2003 (the “Indenture”), between the Company
and the Trustee.  Capitalized terms used
herein and not defined herein have the meanings ascribed thereto in the
Indenture.  The Securities are subject
to all such terms, and Securityholders are referred to the Indenture for a
statement of those terms.

The Securities are general unsecured obligations of
the Company limited to $230,000,000 aggregate principal amount (subject to
Section 2.02 and 2.07 of the Indenture).

5.             Redemption at the
Option of the Company

Prior to July 1, 2003, the Securities will not be
redeemable at the option of the Company. 
Beginning on July 1, 2003, the Company may redeem the Securities for
cash as a whole at any time, or from time to time in part, upon not less than
10 days’ nor more than 60 days’ notice at the following prices (the “Redemption
Price”) (expressed as percentages of the principal amount), together
with accrued and unpaid interest to, but excluding, the Redemption Date.

If redeemed prior to July 1, 2004, the Redemption
Price shall be 105% of the principal amount, plus accrued and unpaid interest
thereon.  Beginning on July 1, 2004, the
Redemption Price shall be 104% of the principal amount plus accrued and unpaid
interest thereon.  Beginning on July 1,
2005, the Redemption Price shall be 103% of the principal amount plus accrued
and unpaid interest thereon.  Beginning
on July 1, 2006, the Redemption Price shall be 102% of the principal amount
plus accrued and unpaid interest thereon. Beginning on July 1, 2007, the
Redemption Price shall be 101% of the principal amount plus accrued and unpaid
interest thereon.  Beginning on July 1,
2008, the Redemption Price shall be 100% of the principal amount plus accrued
and unpaid interest thereon.

If any Redemption Date is an Interest Payment Date,
then the interest payable on such date shall be paid to the Holder of the
Security on the next preceding Regular Record Date.  No Securities may be redeemed by the Company if an Event of
Default with respect to the payment of interest on the Securities has occurred
and is continuing.

No sinking fund is provided for the Securities.

 

A-5

 

Notice of redemption at the option of the Company
will be mailed at least 30 days but not more than 60 days before the Redemption
Date to each Holder of Securities to be redeemed at the Holder’s registered
address.  If money sufficient to pay the
Redemption Price, together with accrued interest to, but excluding, the
Redemption Date, of all Securities (or portions thereof) to be redeemed on the
Redemption Date is deposited with the Paying Agent prior to or on the
Redemption Date, on and after such date interest ceases to accrue on such
Securities or portions thereof. 
Securities in denominations larger than $1,000 of principal amount may
be redeemed in part but only in multiples of $1,000 of principal amount.

6.             Redemption at the
Option of the Holder Upon a Fundamental Change

(a)           At the option of the Holder and
subject to the terms and conditions of the Indenture, the Company shall become
obligated to redeem the Securities held by such Holder on the date (the “Fundamental
Change Repurchase Date”) (or if such date is not a Business Day, the
next succeeding Business Day) that is 45 days after the date of the Company’s
notice of such Fundamental Change (as defined in the Indenture) occurring on or
prior to July 1, 2009 at 100% of the principal amount.  In each case, the Company shall also pay
accrued but unpaid interest, if any, on such Securities to, but excluding, the Fundamental
Change Repurchase Date; provided that if such Fundamental Change Repurchase
Date is an Interest Payment Date, then the interest payable on such date shall
be paid to the Holder of the Security on the next preceding Regular Record
Date.  Securities in denominations
larger than $1,000 of principal amount may be redeemed in part in connection
with a Fundamental Change, but only in multiples of $1,000 of principal amount.

(b)           Holders have the right to withdraw
any Fundamental Change Redemption Notice by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the
Indenture.

(c)           If cash sufficient to pay the
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date, of all Securities or
portions thereof to be purchased as of the Fundamental Change Repurchase Date
is deposited with the Paying Agent on or prior to the Fundamental Change
Repurchase Date, interest ceases to accrue on such Securities (or portions
thereof) on and after the Fundamental Change Repurchase Date, and the Holder
thereof shall have no other rights as such (other than the right to receive the
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date, upon surrender of such
Security).

7.             Denominations;
Transfer; Exchange

 

A-6

 

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

8.             Persons Deemed
Owners

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

9.             Unclaimed Money or
Securities

The Trustee and the Paying Agent shall return to the
Company upon written request any money or securities held by them for the
payment of any amount with respect to the Securities that remains unclaimed for
two years, provided, however, that the Trustee or such Paying Agent, before
being required to make any such return, shall at the expense of the Company
cause to be published once in a newspaper of general circulation in The City of
New York or mail to each such Holder notice that such money or securities
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication or mailing, any unclaimed
money or securities then remaining will be returned to the Company.  After return to the Company, Holders
entitled to the money or securities must look to the Company for payment as
general creditors unless an applicable abandoned property law designates
another person.

10.          Amendment; Waiver

Subject to certain exceptions set forth in the
Indenture, (i) the Indenture or the Securities may be amended with the written
consent of the Holders of at least a majority in aggregate principal amount of
the Securities at the time outstanding and (ii) certain defaults or
noncompliance with certain provisions may be waived with the written consent of
the Holders of a majority in aggregate principal amount of the Securities at
the time outstanding.  Subject to
certain exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, defect or inconsistency, or to comply with
Article 5 of the Indenture, to provide 

 

A-7

 

for uncertificated
Securities in addition to or in place of certificated Securities or to make any
change that does not adversely affect the rights of any Securityholder or to
comply with any requirement of the SEC in connection with the qualification of
the Indenture under the TIA.

11.          Defaults and Remedies

Under the Indenture, Events of Default include (i)
default in payment of the principal amount, Redemption Price or Fundamental
Change Redemption Price, as the case may be, in respect of the Securities when
the same becomes due and payable; (ii) default for 30 days in the payment of
any installment of interest (including an Additional Interest Payment) on the
Securities; (iii) failure by the Company to comply with other agreements in the
Indenture or the Securities, subject to notice and lapse of time; provided,
that the Company’s failure to comply with its agreement set forth in Section
2.15(a) or (b) shall not constitute an Event of Default under the Securities or
under the Indenture and thus, Holders shall not be entitled to exercise the
remedies set forth herein or in Article 6 of the Indenture, but shall be
limited to the remedy set forth in Section 2.15 of the Indenture, (iv) an event
of default under the Secured Credit Facility, the Old Notes Indenture or the
New Convertible Indenture shall have occurred that results in the principal
amount of and accrued interest on that debt becoming immediately due and
payable, and (v) certain events of bankruptcy or insolvency.  If an Event of Default occurs and is
continuing, the Trustee, or the Holders of at least 25% in aggregate principal
amount of the Securities at the time outstanding, may declare all the
Securities to be due and payable immediately. 
Certain events of bankruptcy or insolvency are Events of Default which
will result in the Securities being declared due and payable immediately upon
the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture.  The Trustee may refuse to enforce the Indenture or the Securities
unless it receives reasonable indemnity or security.  Subject to certain limitations, Holders of a majority in
aggregate principal amount of the Securities at the time outstanding may direct
the Trustee in its exercise of any trust or power.  The Trustee may withhold from Securityholders notice of any continuing
Default (except a Default in payment of amounts specified in  (i) or (ii) above) if it determines that
withholding notice is in their interests.

12.          Trustee Dealings with
the Company

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

 

A-8

 

13.          No Recourse Against
Others

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

14.          Authentication

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

15.          Abbreviations

Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT
(=tenants by the entireties), JT TEN (=joint tenants with right of survivorship
and not as tenants in common), CUST (=custodian), and U/G/M/A (Uniform Gift to
Minors Act).

16.          Governing Law

THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE
INDENTURE AND THIS SECURITY.

The Company will furnish to any Securityholder upon
written request and without charge a copy of the Indenture which has in it the

Paying Agent to Hold Money and Securities in Trust.  Except as otherwise provided
herein, prior to or on each due date of payments in respect of any Security,
the Company shall deposit with the Paying Agent a sum of money or securities
sufficient to make such payments when so becoming due.  The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold
in trust for the benefit of Securityholders or the Trustee all money and
securities held by the Paying Agent for the making of payments in respect of
the Securities and shall notify the Trustee of any default by the Company in
making any such payment.  At any time
during the continuance of any such default, the Paying Agent shall, upon the
written request of the Trustee, forthwith pay to the Trustee all money and
securities so held in trust.  If the
Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent,
it shall segregate the money and securities held by it as Paying Agent and hold
it as a separate trust fund.  The
Company at any time may require a Paying Agent to pay all money and securities
held by it to the Trustee and to account for any funds and securities disbursed
by it.  Upon doing so, the Paying Agent
shall have no further liability for the money or securities.

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

Section 2.06. 
Exchange and Registration of Transfer of Securities; Depositary.  Upon surrender for
registration of transfer of any Security at any office or agency of the Company
designated as Registrar or co-registrar pursuant to Section 2.03 and satisfaction
of the requirements for such transfer set forth in this Section 2.06, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
any authorized denominations and of a like aggregate principal amount.

Securities may be exchanged
for a like aggregate principal amount of Securities of other authorized
denominations.  Securities to be
exchanged shall be surrendered at any office or agency to be maintained by the
Company designated as Registrar or co-registrar pursuant to Section 2.03 and
the Company shall execute and register and the Trustee shall authenticate and
deliver in exchange therefor the Security or Securities which the
Securityholder making the exchange shall be entitled to receive, bearing
registration numbers not contemporaneously outstanding.

All Securities presented for
registration of transfer or for exchange, purchase, redemption, conversion or
payment shall (if so required by the Company, the Trustee, the Registrar or any
co-registrar) be duly endorsed by, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Trustee,
duly executed by the Holder or his attorney duly authorized in writing.

No service charge shall be
charged to the Securityholder for any exchange or registration of transfer of
Securities, but the Company 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 Registrar or any co-registrar shall be required to exchange or
register a transfer of (a) any Securities for a period of 15 days next
preceding any selection of Securities to be redeemed or (b) any Securities or
portions thereof selected or called for redemption or (c) any Securities or
portion thereof surrendered for conversion or (d) any Securities or portion
thereof surrendered for redemption (and not withdrawn) pursuant to Section 3.08.

All Securities issued upon
any transfer or exchange of Securities shall be valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this
Indenture as the Securities surrendered upon such exchange or transfer.

The provisions of Clauses
(a), (b), (c), (d), and (e) below shall apply only to Global Securities:

11

 

(a)   Each Global Security authenticated under this
Indenture shall be registered in the name of the Depositary designated for such
Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or Custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture.

(b)   Notwithstanding any other provision in this
Indenture, no Global Security may be exchanged in whole or in part for
Securities registered, and no transfer of a Global Security in whole or in
party may be registered, in the name of any Person other than the Depositary for
such Global Security or a nominee thereof unless (A) such Depositary (i) has
notified the Company that it is unwilling or unable to continue as Depositary
for such Global Security or (ii) has ceased to be a clearing agency registered
under the Exchange Act, or (B) there shall have occurred and be continuing an
Event of Default with respect to such Global Security.

(c)   Subject to 2.06(b) above, any exchange of a
Global Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a Global Security or any portion thereof
shall be registered in such names as the Depositary for such Global Security
shall direct.

(d)   Every Security authenticated and delivered
upon registration of transfer of, or in exchange for or in lieu of, a Global
Security or any portion thereof whether pursuant to this Article Two or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof.

(e)   The Depositary or its nominee, as registered
own of a Global Security, shall be the Holder of such Global Security for all
purposes under the Indenture and the Securities, and owners of beneficial
interests in a Global Security shall hold such interests pursuant to the
applicable procedures.  Accordingly, any
such owner’s beneficial interest in a Global Security will be shown only on,
and the transfer of such interest shall be effected only through, records
maintained by the Depositary or its nominee or its agent members and such
owners of beneficial interests in a Global Security will not be considered the
owners or holders thereof.

The Depositary shall be a
clearing agency registered under the Exchange Act.  The Company initially appoints The Depository Trust Company to
act as Depositary with respect to the Securities in global form.  Initially, the Global Security shall be
issued to the Depositary, registered in the name of Cede & Co., as the
nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co.

12

 

If at any time the
Depositary for the Global Security notifies the Company that it is unwilling or
unable to continue as Depositary for such Global Security, the Company may
appoint a successor Depositary with respect to such Security.  If a successor Depositary for the Global
Security is not appointed by the Company within 90 days after the Company
receives such notice, the Company will execute, and the Trustee, upon receipt
of a Company Order for authentication and delivery of Securities, will
authenticate and deliver, Securities in definitive form, in an aggregate
principal amount equal to the principal amount of the Global Security, in
exchange for such Security in the global form.

Section 2.07. 
Replacement Securities.  If (i) any
mutilated Security is surrendered to the Trustee, or (ii) the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Security, and there is delivered to the Company and the Trustee
such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company or the Trustee that
such Security has been acquired by a bona fide purchaser, the Company shall
execute and upon its written request the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor and principal
amount, bearing a number not contemporaneously outstanding.

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

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

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

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

Section 2.08. 
Outstanding Securities; Determinations of Holders’ Action.  Securities outstanding at
any time are all the Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation and 

13

 

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

If a Security is replaced
pursuant to Section 2.07, it ceases to be outstanding unless the Trustee
receives proof satisfactory to it that the replaced Security is held by a bona
fide purchaser.

If the Paying Agent holds,
in accordance with this Indenture, on a Redemption Date, on a Fundamental
Change Repurchase Date or on Stated Maturity, money or securities, if permitted
hereunder, sufficient to pay Securities payable on that date, then on and after
that date such Securities shall cease to be outstanding and interest on such
Securities shall cease to accrue; provided, that if such Securities are to be
redeemed, notice of such redemption has been duly given pursuant to this
Indenture or provision therefor satisfactory to the Trustee has been made.

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

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

If temporary Securities are
issued, the Company will cause definitive Securities to be prepared without
unreasonable delay.  After the preparation
of definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 2.03,
without 

14

 

charge
to the Holder.  Upon surrender for
cancellation of any one or more temporary Securities the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations.  Until so exchanged the temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

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

Section 2.11. 
Persons Deemed Owners.  Prior to due
presentment of a Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name such Security is registered as the owner of such Security for the
purpose of receiving payment of principal amount, premium, if any, interest,
Redemption Price and Fundamental Change Redemption Price in respect thereof,
for the purpose of conversion and for all other purposes whatsoever, whether or
not such Security be overdue, and none of the Company, the Trustee or any agent
of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12. 
Payment of Interest; Interest Rights Preserved.  Interest on any Security
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest.

Any interest on any Security
which is payable, but is not punctually paid or dully provided for, on any
Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease
to be payable to the Holder on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in (a) or (b) below:

15

 

(a)   The Company may elect to make payment of any
Defaulted Interest to the Persons in whose names the Securities (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner.  The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such
deposit on or prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix
a Special Record Date for the payment of such Defaulted Interest which shall be
not more than 15 days and not less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment.  The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder at his address as it
appears in the Security Register, not less than 10 days prior to such Special
Record Date.  Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having
been so mailed, such Defaulted Interest shall be paid to the Persons in whose
names the Securities (or their respective Predecessor Securities) are
registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following Clause (b).

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

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

In the case of any Security
which is converted after any Regular Record Date on or prior to the close of
business on the next succeeding Interest Payment Date (other than any Security
whose Maturity is prior to such Interest Payment Date), interest whose Stated
Maturity is on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion, and such interest (whether or not
punctually paid or dully provided for) shall be paid 

16

 

to
the Person whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date.  Except as otherwise expressly provided in
the immediately preceding sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of such
Security shall not be payable.

Section 2.13. 
Computation of Interest.  Interest on the
Securities shall be computed on the basis of a 360-day year of twelve 30-day
months.

Section 2.14. 
Preservation of Information; Communications to Holders.

(a)   The Trustee shall preserve, in as current a
form as is reasonably practicable, the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 2.05
and the names and addresses of Holders received by the Trustee in its capacity
as Security Registrar.  The Trustee may
destroy any list furnished to it as provided in Section 2.05 upon receipt of a
new list so furnished.

(b)   The rights of Holders to communicate with
other Holders with respect to their rights under this Indenture or under the
Securities, and the corresponding right and duties of the Trustee, shall be as
provided in the TIA.

(c)   Every Holder of Securities, by receiving and
holding the same, agrees with the Company and the Trustee that neither the Company
nor the Trustee nor any agent of either of them shall be held accountable by
reason of the disclosure of information as to names and addresses of the
Holders made pursuant to the TIA.

Section 2.15. 
Reduction Of Conversion Price.  The Conversion
Price of  any Security shall be reduced
in the circumstances described under Section 2.15(c) and (d) below:

(a)   The Company shall maintain EBITDA (as defined
herein) of not less than (i) $0.00  for
the fiscal quarters ending on December 26, 2003 and June 25, 2004, and (ii)
($5,000,000) for the fiscal quarters ending on March 26, 2004 and September 24,
2004.  “EBITDA” shall be defined for
purposes of this Section 2.15 as the Company’s consolidated net earnings (or
loss), plus net interest expense, income taxes, depreciation and amortization
for the relevant fiscal quarter, as determined in accordance with GAAP and as
reported by the Company in the cash flow statement included in its quarterly
report on Form 10-Q filed with the SEC relating to such fiscal quarter.  All non-cash restructuring charges and any
extraordinary losses for the applicable fiscal quarter shall be eliminated in
the calculation of EBITDA for purposes of determining compliance with this
condition.

17

 

(b)   The Company shall, on or prior to December
31, 2003, reduce the aggregate principal amount of Securities and New
Convertible Notes (together, the “2009 Notes”) outstanding on the date hereof
by $25 million; provided that any purchases by the Company of up to $10 million
principal amount of Old Notes at a price (excluding commissions and other costs
of sale) equal to 85% or less of their principal amount shall be deemed a
reduction by an equal dollar amount of the outstanding principal amount of 2009
Notes. The Company may satisfy this obligation through open market or private
purchases or by initiating a cash tender offer at par (plus accrued interest)
for 2009 Notes and accepting and paying for sufficient 2009 Notes to satisfy
this condition.  In the event that less
than the aggregate principal amount of 2009 Notes required to satisfy this
condition are tendered, the Company’s acceptance of and payment for any and all
New Notes validly tendered will fully satisfy its obligations under this
paragraph.

(c)   If the Company shall not have satisfied the
condition set forth in Section 2.15(a) above in any fiscal quarter to which
such condition applies, the Conversion Price of the Securities shall be reduced
from $1.85 per share of Common Stock to $1.50 per share of Common Stock for the
next succeeding fiscal quarter, subject to adjustment as set forth in Section
10 below.

(d)   If the Company shall have satisfied the
condition set forth in Section 2.15(a) above in any fiscal quarter to which
such condition applies, but the Company has not reduced the outstanding
principal amount of 2009 Notes as required by Section 2.15(b), the Conversion
Price of the Securities shall be reduced from $1.85 per share of Common Stock
to $1.50 per share of Common Stock, subject to adjustment as set forth in
Section 10 below, until it has fully satisfied its obligations under Section
2.15(b).

Section 2.16. 
Company’s Use Of Proceeds From Sale Of Certain Assets.  (a) Until the Company has
complied in full with its obligation set forth in Section 2.15(b) above, it
agrees that it will apply at least 50% of its net cash proceeds from the sale
of (i) businesses, (ii) material fixed assets or patents (other than in
connection with a commercial transaction in which the patents are related to
the subject matter of the transaction) and (iii) its or its Affiliates’ equity
securities to satisfy such obligation; provided, however that amounts from such
sales will be applied first as required by the terms of the Company’s Secured
Credit Facility and thereafter to the satisfaction of its obligation set forth
in Section 2.15(b).  For purposes of
this Section 2.16, “net cash proceeds” shall be deemed, as to any sale
transaction, as an amount equal to (i) the aggregate amount received in cash
(including any cash received by way of deferred payment pursuant to a note
receivable, installment receivable, purchase price adjustment receivable or
otherwise, but only as and when such cash is received) from such sales
transaction, less (ii) the reasonable out-of-pocket expenses and fees incurred
in connection with such sale.

18

 

(b)   Upon consummation of a sale transaction
described in Section 2.16(a) above, the Company shall provide the Trustee a
certificate signed by its Chief Financial Officer setting forth (i) a
calculation of the net cash proceeds from such transaction, including an
itemization of fees and expenses and (ii) certifying, in accordance with the
provisions of Section 11.05 that the Company has complied with its obligations
under Section 2.16(a) with respect to the application of such proceeds.

Section 2.17. 
Right Of Holders Of 2009 Notes To Appoint Directors.  (a) The Company agrees that it
will, as soon as reasonably practicable after submission to the Corporate
Secretary of a written request executed by the Holders of a majority in
principal amount of the 2009 Notes setting forth the names of two nominees to
serve on the Board of Directors, appoint such nominees, provided that such
nominees are reasonably acceptable to the nominating committee of the Board of
Directors.  The Company will include
such nominees in the slate of candidates for the Board of Directors who have
been nominated for terms of  at least
two years at the next annual meeting of shareholders.  In addition, for any period in which the Company is required to
reduce the Conversion Price pursuant to Section 2.15(c) or (d) above, the
Holders of a majority in interest of the 2009 Notes shall be entitled to name a
third member of the Board of Directors who is reasonably acceptable to the
Board’s nominating committee in accordance with the procedures set forth
above.  The term of such director shall
end automatically, and such director shall promptly submit his or her
resignation from the Board of Directors, when the reduction in Conversion Price
pursuant to Section 2.15(c) or (d) above is no longer in effect.

(b)   In the event of a vacancy on the Board of
Directors created by the death or resignation of a director appointed by the
Holders of the 2009 Notes pursuant to Section 2.17(a) above (other than an
automatic resignation resulting from the expiration of the period during which
the Conversion Price is reduced), such vacancy may be filled, after
consultation with the Holders of 2009 Notes, by the remaining directors or
director named by the Holders of 2009 Notes, provided that such replacement
director is reasonably acceptable to the nominating committee of the Board of
Directors.

ARTICLE 3

Redemption

Section 3.01. 
Right to Redeem; Notices to Trustee. 
The Company, at its option, may redeem the Securities in accordance
with the provisions of paragraph 5 of the Securities.  If the Company elects to redeem Securities pursuant to paragraph
5 of the Securities, it shall notify the Trustee in writing of the Redemption
Date, the principal amount of Securities to be redeemed, the 

19

 

Redemption Price, and the
amount of accrued interest to, but excluding, the Redemption Date.

The Company shall give the
notice to the Trustee provided for in this Section 3.01 (i) in the case of any
redemption of fewer than all of the Securities, at least 45 days before the
Redemption Date and (ii) in the case of a redemption of all of the Securities,
no later than the Company is required to give notice to the Holders pursuant to
Section 3.03, in each case unless a shorter notice shall be satisfactory to the
Trustee.

Section 3.02. 
Selection of Securities to be Redeemed. 
If less than all the Securities are to be redeemed, the Trustee shall
select the Securities to be redeemed pro rata or by lot or by a method the
Trustee considers fair and appropriate (as long as such method is not
prohibited by the rules of any stock exchange or automated quotation system on
which the Securities are then listed). 
The Trustee shall make the selection at least 10 days, but not more than
60 days, before the Redemption Date from outstanding Securities not previously
called for redemption.  The Trustee may
select for redemption portions of the principal amount of Securities that have
denominations larger than $1,000. 
Securities and portions of Securities selected by the Trustee shall be
in principal amounts of $1,000 or a multiple of $1,000.  Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called
for redemption.  The Trustee shall
notify the Company promptly of the Securities or portions of Securities to be
redeemed.

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

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

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

(a)   the Redemption Date;

(b)   the Redemption Price, together with the amount
of accrued interest to, but excluding, the Redemption Date;

(c)   the Conversion Price;

20

 

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

(e)   that Securities called for redemption may be
converted at any time before the close of business on the last Trading Day
prior to the Redemption Date;

(f)    that Holders who want to convert Securities
must satisfy the requirements set forth in paragraph 7 of the Securities;

(g)   that Securities called for redemption must be
surrendered to the Paying Agent to collect the Redemption Price and accrued
interest to, but excluding, the Redemption Date;

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

(i)    that interest on Securities called for
redemption will cease to accrue on and after the Redemption Date.

At the Company’s request,
the Trustee shall give the notice of redemption in the Company’s name and at
the Company’s expense.

Section 3.04. 
Effect of Notice of Redemption.  Once notice of
redemption is given, Securities called for redemption become due and payable on
the Redemption Date and at the Redemption Price, together with accrued interest
to, but excluding, the Redemption Date, stated in the notice except for
Securities which are converted in accordance with the terms of this Indenture.

Upon the later of the
Redemption Date or the date such Securities are surrendered to the Paying Agent,
such Securities shall be paid at the Redemption Price, together with accrued
interest to, but excluding, the Redemption Date, stated in the notice.

Section 3.05. 
Deposit of Redemption Price.  Prior to or on
the Redemption Date, the Company shall deposit with the Paying Agent (or if the
Company or a Subsidiary or an Affiliate of either of them is the Paying Agent,
shall segregate and hold in trust) money sufficient to pay the Redemption Price
and accrued interest to, but excluding, the Redemption Date of all Securities
to be redeemed on that date other than Securities or portions of Securities
called for redemption which prior thereto have been delivered by the Company to
the Trustee for cancellation or have been converted; provided that if such
payment is made on the Redemption Date it must be received by the Trustee or
Paying Agent, as the case may be, by 10:00 a.m.  New York City time, on such Redemption Date.  The Paying Agent shall as promptly as
practicable return to the Company any money, with interest, if any, thereon
(subject to the provisions 

21

 

of Section 7.01(f)), not
required for that purpose because of conversion of Securities.  If such money is then held by the Company in
trust and is not required for such purpose it shall be discharged from such
trust.

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

Section 3.07. 
Conversion Arrangement on Call for Redemption.  In connection with any redemption of Securities, the
Company may arrange for the purchase and conversion of any Securities called
for redemption by an agreement with one or more investment bankers or other
purchasers to purchase such Securities by paying to the Paying Agent in trust
for the Securityholders, on or before the close of business on the Redemption
Date, an amount that, together with any amounts deposited with the Paying Agent
by the Company for the redemption of the Securities, is not less than the
Redemption Price, together with interest, if any, accrued to the Redemption
Date, of such Securities. 
Notwithstanding anything to the contrary contained in this Article 3,
the obligation of the Company to pay the Redemption Price of such Securities,
including all accrued interest, shall be deemed to be satisfied and discharged
to the extent such amount is so paid by such purchasers.  If such an agreement is entered into, any
Securities not duly surrendered for conversion by the Holders thereof may, at
the option of the Company, be deemed, to the fullest extent permitted by law,
acquired by such purchasers from such Holders and (notwithstanding anything to
the contrary contained in Article 10) surrendered by such purchasers for
conversion, all immediately prior to the close of business on the Redemption
Date, subject to payment of the above amount as aforesaid.

The Paying Agent shall hold
and pay to the Holders whose Securities are selected for redemption any such
amount paid to it in the same manner as it would moneys deposited with it by
the Company for the redemption of Securities. 
Without the Paying Agent’s prior written consent, no arrangement between
the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Paying Agent as set forth in this
Indenture, and the Company agrees to indemnify the Paying Agent from, and hold
it harmless against, any loss, liability or expense arising out of or in
connection with any such arrangement for the purchase and conversion of any
Securities between the Company and such purchasers, including the costs and
expenses incurred by the Paying Agent in the defense of any claim or liability
arising out of or in connection with the exercise or performance of any of its
powers, duties, responsibilities or obligations under this Indenture.

Section 3.08. 
Redemption at Option of the Holder upon a Fundamental Change.  (a)  If a Fundamental Change
shall occur at any time prior to July 1, 2009, each Holder of Securities shall
have the right, at such Holder’s option, to require the Company to redeem such
Holder’s Securities on the date (the “Fundamental Change Repurchase Date”) (or if
such date is not a Business Day, the next succeeding Business Day) that is 45
days after the date of the Company’s notice of such Fundamental Change.  The Securities will be redeemable in part in
multiples of $1,000 of principal amount. 
Such repayment shall be made at 100% of the principal amount (the “Fundamental
Change Redemption Price”) thereof. In each case, the Company shall
also pay to such Holders accrued interest to, but excluding, the Fundamental
Change Repurchase Date on the redeemed Securities; provided that if such
Fundamental Change Repurchase Date is an Interest Payment Date, then the
interest payable on such date shall be paid to the Holder of the Security on
the next preceding the Regular Record Date.

(b)   On or before the tenth day after the
occurrence of a Fundamental Change, the Company, or, at its written request
(which must be received by the Trustee at least five Business Days prior to the
date the Trustee is requested to give notice as described below), the Trustee
in the name of and at the expense of the Company, shall mail or cause to be
mailed to all Holders of record on the date of the Fundamental Change a notice
(the “Company
Notice”) of the occurrence of such Fundamental Change and of the
redemption right at the option of the Holders arising as a result thereof.  Such notice shall be mailed in the manner
and with the effect set forth in Section 3.03. 
The Company shall also deliver a copy of the Company Notice to the
Trustee at such time as it is mailed to the Holders.

Each Company Notice shall
specify the circumstances constituting the Fundamental Change, the Fundamental
Change Repurchase Date, the Fundamental Change Redemption Price at which the
Company shall be obligated to redeem the Securities, the amount of interest
accrued on each Security to, but excluding, the Fundamental Change Repurchase
Date, the latest time by which the Holder must exercise the redemption right
(the “Fundamental
Change Expiration Time”), that the Holder shall have the right to
withdraw any Notes prior to the Fundamental Change Expiration Time, a description
of the procedure which a Holder must follow to exercise such redemption right
and to withdraw any surrendered Notes and the place or places where the Holder
is to surrender such Holder’s Securities.

No failure of the Company to
give the foregoing notices and no defect therein shall limit the Holders’
redemption rights or affect the validity of the proceedings for the repurchase
of the Securities pursuant to this Section 3.08.

(c)   For a Security to be so redeemed at the
option of the Holder, the Paying Agent must receive such Security with the form
entitled “Option to Elect 

23

 

Redemption Upon a
Fundamental Change” on the reverse thereof duly completed (a “Fundamental
Change Redemption Notice”), together with such Security duly
endorsed for transfer, on or before the 30th day after the date of such Company
Notice (or if such 30th day is not a Business Day, the immediately preceding
Business Day).  All questions as to the
validity, eligibility (including time of receipt) and acceptance of any
Security for redemption shall be determined by the Company, whose determination
shall be final and binding.

(d)   Upon receipt by the Company of the
Fundamental Change Redemption Notice specified in Section 3.08(c), the Holder
of the Security in respect of which such Fundamental Change Redemption Notice
was given shall (unless such Fundamental Change Redemption Notice is withdrawn
as specified in the following two paragraphs) thereafter be entitled to receive
solely the Fundamental Change Redemption Price, together with accrued interest
to, but excluding, the Fundamental Change Repurchase Date, with respect to such
Security.  Such Fundamental Change
Redemption Price together with accrued interest to, but excluding, the Fundamental
Change Repurchase Date, shall be paid to such Holder promptly following the
Fundamental Change Repurchase Date. 
Securities in respect of which a Fundamental Change Redemption Notice
has been given by the Holder thereof may not be converted into shares of Common
Stock on or after the date of the delivery of such Fundamental Change
Redemption Notice, unless such Fundamental Change Redemption Notice has first
been validly withdrawn as specified in the following two paragraphs.

A Fundamental Change Redemption
Notice may be withdrawn by the Holder by means of a written notice of
withdrawal delivered to the office of the Paying Agent at any time prior to the
close of business on the Fundamental Change Repurchase Date to which it relates
specifying:

(i)    the certificate number of
the Security in respect of which such notice of withdrawal is being submitted,

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

(iii)  the principal amount, if
any, of such Security which remains subject to the original Fundamental Change
Redemption Notice and which has been or will be delivered for purchase by the
Company.

There shall be no redemption
pursuant to Section 3.08 if there has occurred prior to, on or after, as the
case may be, the giving, by the Holders of such Securities, of the required
Fundamental Change Redemption Notice and is continuing an Event of Default
(other than a default in the payment of the Fundamental Change Redemption
Price, together with accrued interest to, but 

24

 

excluding, the Fundamental Change Repurchase Date, with respect to such
Securities).

(e)   On or before the Fundamental Change
Repurchase Date the Company shall deposit with the Trustee or with the Paying
Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is
acting as the Paying Agent, shall segregate and hold in trust as provided in
Section 2.04) an amount of money and/or securities, if permitted hereunder, sufficient
to pay the aggregate Fundamental Change Redemption Price, together with accrued
interest to, but excluding, the Fundamental Change Repurchase Date, of all the
Securities or portions thereof which are to be redeemed as of such Fundamental
Change Repurchase Date; provided that if such payment is made on the
Fundamental Change Repurchase Date it must be received by the Trustee or Paying
Agent, as the case may be, by 10:00 a.m. 
New York City time, on such Fundamental Change Repurchase Date.

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

(g)   In connection with any offer to redeem
Securities under Section 3.08 hereof the Company shall comply with all Federal
and state securities laws so as to permit the rights and obligations under
Section 3.08 to be exercised in the time and in the manner specified in Section
3.08.

(h)   The Trustee and the Paying Agent shall return
to the Company any cash that remains unclaimed as provided in paragraph 11 of
the Securities, together with interest or dividends, if any (subject to the
provisions of Section 7.01(f)), thereon, held by them for the payment of a
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date; provided, however that to
the extent that the aggregate amount of cash deposited by the Company pursuant
to Section 3.08 exceeds the aggregate Fundamental Change Redemption Price,
together with accrued interest to, but excluding, the Fundamental Change
Repurchase Date, of the Securities or portions thereof which the Company is
obligated to purchase as of the Fundamental Change Repurchase Date then
promptly after the Business Day following the Fundamental Change Repurchase
Date the Trustee and the 

25

 

Paying Agent shall return
any such excess to the Company together with interest or dividends, if any,
thereon.

The Company may also from
time to time designate one or more other offices or agencies where the
Securities may be presented or surrendered for any or all such purposes and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The
City of New York, for such purposes.

(a)   the Person (if other than the Company) formed

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.01. 
Events of Default.  “Event of
Default” occurs if:

(a)   the Company defaults in the payment of the
principal amount of, premium, if any, Redemption Price or Fundamental Change
Redemption Price on any Security when the same becomes due and payable at its
Stated Maturity, upon redemption, upon declaration or otherwise;

(b)   the Company defaults in the payment of any
installment of interest upon any of the Securities as and when the same shall
become due and payable, and continuance of such default for 30 days;

(c)   the Company fails to comply with any of its
agreements in the Securities or this Indenture (other than those referred to in
clause (a) or (b) above and those set forth in Section 2.15(a) and (b) hereof,
as to which the exclusive remedy is set forth in Section 2.15) and such failure
continues for 60 days after receipt by the Company of a Notice of Default;

(d)   a decree or order by a court having
jurisdiction in the premises shall have been entered adjudging the Company a
bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization of the Company under any Bankruptcy Law, and such decree or
order shall have continued undischarged and unstayed for a period of 60
consecutive days; or a decree or order of a court having jurisdiction in the
premises of the appointment of a receiver or liquidator or trustee or assignee
in bankruptcy or insolvency of the Company or of its property, or for the
winding-up or liquidation of its affairs, shall have been entered, and such
decree or order shall have remained in force undischarged and unstayed of a
period of 60 consecutive days; or

(e)   the Company shall institute proceedings to be
adjudicated a voluntary bankrupt, or shall consent to the filing of a
bankruptcy proceeding against it, or shall file a petition or answer or consent
seeking reorganization under any Bankruptcy Law, or shall consent to the filing
of any such petition, or shall consent to the appointment of a receiver or
liquidator or trustee or assignee in bankruptcy or insolvency of it or of its
property or shall make an assignment for the benefit of creditors, or shall
admit in writing its inability to pay its debts generally as they become due.

(f)    an event of default under the Secured Credit
Facility, the Old Notes Indenture or the New Convertible Indenture shall have
occurred which results in the principal amount and accrued interest on that
debt becoming immediately due and payable.

30

 

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

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

Section 6.02. 
Acceleration.  If an Event of
Default (other than an Event of Default specified in Section 6.01(d) or (e))
occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in aggregate principal amount of the Securities at the time
outstanding by notice to the Company and the Trustee, may declare the principal
amount and premium, if any, on all the Securities and the interest accrued
thereon to be immediately due and payable. 
Upon such a declaration, such principal amount, premium, if any, and
interest accrued thereon shall be due and payable immediately.  If an Event of Default specified in Section
6.01(d) or (e) occurs and is continuing, the principal amount and premium, if
any, on all the Securities and the interest accrued thereon shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders.  The
Holders of a majority in aggregate principal amount of the Securities at the
time outstanding, by notice to the Trustee (and without notice to any other
Securityholder) may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of the principal
amount, premium, if any, and interest accrued thereon that has become due
solely as a result of acceleration and if all amounts due to the Trustee under
Section 7.07 have been paid.  No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.

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

The Trustee may maintain a
proceeding even if the Trustee does not possess any of the Securities or does
not produce any of the Securities in the proceeding.  A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of 

31

 

Default.  No remedy is exclusive of any other remedy.  All available remedies are cumulative.

Section 6.04. 
Waiver of Past Defaults.  The Holders of
a majority in aggregate principal amount of the Securities at the time
outstanding, by notice to the Trustee (and without notice to any other
Securityholder), may waive an existing Default and its consequences except (1)
an Event of Default described in Section 6.01(a) or 6.01(b), (2) a Default in
respect of a provision that under Section 9.02 cannot be amended without the
consent of each Securityholder affected, or (3) a Default that constitutes a
failure to convert any Security in accordance with the terms of Article
10.  When a Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

Section 6.05. 
Control by Majority.  The Holders of
a majority in aggregate principal amount of the Securities at the time
outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power
conferred on the Trustee.  However, the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture or that the Trustee determines in good faith is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability unless the Trustee is offered indemnity satisfactory to it.

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

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

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

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

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

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

32

 

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

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

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

Section 6.09. 
Trustee May File Proofs of Claim. 
In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal amount, premium,
if any, accrued interest, Redemption Price or Fundamental Change Redemption
Price in respect of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment of any such
amount) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

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

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

33

 

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

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

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

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

Second:  to Securityholders for amounts due and
unpaid on the Securities for the principal amount, premium, if any, accrued
interest, Redemption Price or Fundamental Change Redemption Price, as the case
may be, ratably, without preference or priority of any kind, according to such amounts
due and payable on the Securities; and

Third:  the balance, if any, to the Company.

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

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

Section 6.12. 
Waiver of Stay, Extension or Usury Laws.  The Company covenants (to the extent that it may
lawfully do so) that it will not at any time 

34

 

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

ARTICLE 7

TRUSTEE

Section 7.01. 
Duties of Trustee.  (a)  If
an Event of Default has occurred and is continuing, the Trustee shall exercise
the rights and powers vested in it by this Indenture and use the same degree of
care and skill in its exercise as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

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

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

(ii)   in the absence of bad faith
on its part, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the
requirements of this Indenture. However, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the
requirements of this Indenture.

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

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

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

35

 

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

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

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

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

Section 7.02. 
Rights of Trustee.  (a) The Trustee
may rely on any document believed by it to be genuine and to have been signed
or presented by the proper person.  The
Trustee need not investigate any fact or matter stated in the document.

(b)   Before the Trustee acts or refrains from
acting, it may require a Company Order, an Officers’ Certificate or an Opinion
of Counsel.  The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Company Order, Officers’ Certificate or Opinion of Counsel.

(c)   The Trustee may act through agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

(d)   Subject to the provisions of Section 7.01(c),
the Trustee shall not be liable for any action it takes or omits to take in
good faith which it believes to be authorized or within its rights or powers.

Section 7.03. 
Individual Rights of Trustee.  The Trustee in
its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or its Affiliates with the
same rights it would have if it were not Trustee.  Any Paying Agent, Registrar, Conversion Agent or co-registrar may
do the same with the like rights. 
However, the Trustee must comply with Section 7.10.

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

36

 

Section 7.05. 
Notice of Defaults.  If a Default
occurs and is continuing and if it is known to the Trustee, the Trustee shall
give to each Securityholder notice of the Default within 90 days after it
occurs.  Except in the case of a Default
described in Section 6.01(a) or 6.01(b), the Trustee may withhold the notice if
and so long as a committee of its Trust Officers in good faith determines that
withholding the notice is in the interests of Securityholders.  The Trustee shall not give notice of a
Default pursuant to Section 6.01(c) until at least sixty (60) days have passed
since its occurrence.

Section 7.06. 
Disqualification; Conflicting Interests.  If the Trustee has or shall acquire any conflicting
interest within the meaning of the TIA, it shall either eliminate such
conflicting interest or resign, to the extent and in the.  manner provided by, and subject to the provisions
of the TIA and this Indenture.

Section 7.07.  Compensation and Indemnity.  The
Company agrees:

(a)   to pay to the Trustee from time to time
reasonable compensation for all services rendered by it hereunder (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust);

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

(c)   to indemnify the Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence or
bad faith on its part, arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

To secure the Company’s
payment obligations in this Section 7.07, the Trustee shall have a lien prior
to the Securities on all money or property held or collected by the Trustee,
except that held in trust to pay the principal amount, premium, if any, accrued
interest, Redemption Price or Fundamental Change Redemption Price, as the case
may be, on particular Securities.

The Company’s payment
obligations pursuant to this Section 7.07 shall survive the discharge of this
Indenture.  When the Trustee incurs
expenses after the occurrence of a Default specified in Section 6.01(d) or (e),
the expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

37

 

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

(a)   the Trustee fails to comply with, or ceases
to be eligible under, Section 7.10;

(b)   the Trustee is adjudged bankrupt or
insolvent;

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

(d)   the Trustee otherwise becomes incapable of
acting.

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

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

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

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

Section 7.09. 
Successor Trustee by Merger.  If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trustee business or assets (including the administration of
the trust created by this Indenture) to, another corporation, the resulting,
surviving or transferee corporation without any further act shall be the
successor Trustee.

38

 

Section 7.10. 
Eligibility; Disqualification.  The Trustee (or
if a Trustee is a member of a bank holding company, its bank holding company)
shall have a combined capital and surplus of at least $50,000,000 as set forth
in its most recent published annual report of conditions.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.11. 
Preferential Collection of Claims Against Company.  If and when the Trustee
shall be or become a creditor of the Company (or any other obligor upon the
Securities), the Trustee shall be subject to the provisions of the TIA
regarding the collection of claims against the Company (or any such other
obligor).

Section 7.12. 
Reports by Trustee.

(a)   The Trustee shall transmit to Holders such
reports concerning the Trustee and its actions under this Indenture as may be
required pursuant to the TIA at the times and in the manner provided pursuant
thereto.

(b)   A copy of each such report shall, at the time
of such transmission to Holders, be filed by the Trustee with each stock
exchange or market upon which the Securities are listed, with the Commission
and with the Company.  The Company will
notify the Trustee when the Securities are listed on any stock exchange or
market.

ARTICLE 8

DISCHARGE OF INDENTURE

Section 8.01. 
Discharge of Liability on Securities. 
When (i) the Company delivers to the Trustee all outstanding Securities
(other than Securities replaced pursuant to Section 2.07) for cancellation or
(ii) all outstanding Securities have become due and payable and the Company
deposits with the Trustee cash and/or securities, as permitted by the terms
hereof, sufficient to pay at Stated Maturity the principal amount of all
outstanding Securities (other than Securities replaced pursuant to Section
2.07), and if in either case the Company pays all other sums payable hereunder
by the Company, then this Indenture shall, subject to Section 7.07, cease to be
of further effect.  The Trustee shall
join in the execution of a document prepared by the Company acknowledging
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers’ Certificate and Opinion of Counsel and at the cost
and expense of the Company.

Section 8.02. 
Repayment to the Company.  The Trustee and
the Paying Agent shall return to the Company upon written request any money or
securities held by them for the payment of any amount with respect to the
Securities that 

39

 

remains
unclaimed for two years, provided, however, that the Trustee or such Paying
Agent, before being required to make any such return, shall at the expense of
the Company cause to be published once in a newspaper of general circulation in
The City of New York or mail to each such Holder notice that such money or
securities remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication or mailing,
any unclaimed money or securities then remaining will be returned to the
Company.  After return to the Company,
Holders entitled to the money or securities must look to the Company for
payment as general creditors unless an applicable abandoned property law
designates another person.

ARTICLE 9

AMENDMENTS

Section 9.01. 
Without Consent Of Holders.  The Company and
the Trustee may amend this Indenture or the Securities without the consent of
any Securityholder:

(a)   to cure any ambiguity, defect or
inconsistency;

(b)   to comply with Article 5 or Section 10.14;

(c)   to provide for uncertificated Securities in
addition to certificated Securities so long as such uncertificated Securities
are in registered form for purposes of the Internal Revenue Code of 1986, as

(d)   to make any change that does not adversely
affect the right of any Securityholder; or

(e)   to make any change to comply with the TIA, or
any amendment thereto, or to comply with any requirement of the SEC in connection
with the qualification, if any, of the Indenture under the TIA.

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

(a)   make any change to the manner or rate of
accrual in connection with interest, reduce the rate of interest referred to in
paragraph 1 of the Securities or extend the time for payment of interest on any
Security;

(b)   reduce the Redemption Price or extend the
Stated Maturity;

40

 

(c)   reduce the Redemption Price or Fundamental
Change Redemption -Price of any Security;

(d)   make any Security payable in money or
securities other than that stated in the Security;

(e)   make any change in Section 6.04, Section 6.07
or this Section 9.02, except to increase any such percentage;

(f)    make any change that adversely affects the
right to convert any Security; or

(g)   make any change that adversely affects the
right to require the Company to redeem the Securities upon a Fundamental Change
in accordance with the terms thereof and this Indenture;

and
no such amendment or supplement to this Indenture may reduce the aforesaid
percentage of Securities whose Holders must consent to any such amendment or
supplemental indenture, without the consent of the Holders of all the
Securities then outstanding.

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

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

Section 9.03. 
Compliance with TIA.  Every
supplemental indenture executed pursuant to this Article shall comply with the
TIA as then in effect.

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

Section 9.05. 
Notation on or Exchange of Securities. 
Securities authenticated and delivered after the execution of any
supplemental indenture 

41

 

pursuant
to this Article may, and shall if required by the Trustee, bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental
indenture.  If the Company shall so
determine, new Securities so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any such supplemental indenture may be
prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for outstanding Securities,

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

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

ARTICLE 10

CONVERSION

Section 10.01. 
Conversion Privilege.  A Holder of a
Security may convert such Security into Common Stock at any time during the
period stated in paragraph 7 of the Securities.  The conversion price per share of Common Stock (the “Conversion
Price”) shall be that set forth in paragraph 7 in the Securities,
subject to adjustment as herein set forth and subject to reduction as set forth
in Section 2.15.

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

Section 10.02. 
Conversion Procedure.  To convert a
Security a Holder must satisfy the requirements in paragraph 7 of the
Securities.  The date on which the
Holder satisfies all those requirements is the conversion date (the “Conversion
Date”).  Securities
surrendered for conversion during the period from the close of business on any
Regular Record Date to the close of business on the Trading Day immediately
prior to the next succeeding Interest Payment Date 

42

 

(the
“Interest
Period”) shall (except in the case of Securities or portions thereof
which have been called for redemption on a Redemption Date within such Interest
Period) be accompanied by payment in New York Clearing House funds or other
funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the principal amount of Securities being
surrendered for conversion.  Subject to
the provisions of Section 3.07 relating to the payment of Defaulted Interest by
the Company, the interest payment with respect to a Security surrendered for
conversion during the Interest Period (except in the case of Securities or
portions thereof which have been called for redemption on a Redemption Date within
the Interest Period) shall be payable on such Interest Payment Date to the
Holder of such Securities at the close of business on such Regular Record Date
notwithstanding the conversion of such Securities during such Interest Period.

As soon as practicable after
the Conversion Date, the Company shall deliver to the Holder, through the
Conversion Agent, a certificate for the number of full shares of Common Stock
issuable upon the conversion and cash in lieu of any fractional share
determined pursuant to Section 10.03. 
The person in whose name the certificate is registered shall be treated
as a stockholder of record on and after the Conversion Date; provided, however,
that no surrender of a Security on any date when the stock transfer books of
the Company shall be closed shall be effective to constitute the person or
persons entitled to receive the shares of Common Stock upon such conversion as
the record holder or holders of such shares of Common Stock on such date, but
such surrender shall be effective to constitute the person or persons entitled
to receive such shares of Common Stock as the record holder or holders thereof
for all purposes at the close of business on the next succeeding day on which
such stock transfer books are open; such conversion shall be at the Conversion
Price in effect on the date that such Security shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been
closed.  Upon conversion of a Security,
such person shall no longer be a Holder of such Security.

No payment or adjustment
will be made for dividends on or other distribution with respect to any Common
Stock except as provided in this Article 10.

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

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

43

 

If the last day on which a
Security may be converted is a Legal Holiday in a place where a Conversion
Agent is located, the Security may be surrendered to that Conversion Agent on
the next succeeding day that it is not a Legal Holiday.

Section 10.03. 
Fractional Shares.  The Company
will not issue a fractional share of Common Stock upon conversion of a
Security.  Instead, the Company will
deliver cash for the current market value of the fractional share.  The current market value of a fractional
share shall be determined to the nearest 1/10,000th of a share by multiplying
the last reported sale price (determined as set forth in the definition of
Current Market Price), on the last Trading Day prior to the Conversion Date, of
a full share by the fractional amount and rounding the product to the nearest
whole cent.

Section 10.04. 
Taxes on Conversion.  If a Holder
converts a Security, the Company shall pay any documentary, stamp or similar
issue or transfer tax due on the issue of shares of Common Stock upon the
conversion.  However, the Holder shall
pay any such tax which is due because the Holder requests the shares to be
issued in a name other than the Holder’s name. 
The Conversion Agent may refuse to deliver the certificates representing
the Common Stock being issued in a name other than the Holder’s name until the
Conversion Agent receives a sum sufficient to pay any tax which will be due
because the shares are to be issued in a name other than the Holder’s
name.  Nothing herein shall preclude any
tax withholding required by law or regulations.

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

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

The Company will endeavor
promptly to comply with all Federal and state securities laws regulating the
offer and delivery of shares of Common Stock upon conversion of Securities, if
any, and will endeavor promptly, if permitted by the rules of such exchange,
over-the-counter market or other market, to list or cause to have quoted such
shares of Common Stock on each national Securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

Section 10.06. 
Adjustment for Change in Capital Stock. 
In case the Company shall (i) pay a dividend, or make a distribution,
in shares of its Common Stock, on its Common Stock, (ii) subdivide its
outstanding Common Stock into a 

44

 

greater
number of shares, or (iii) combine its outstanding Common Stock into a smaller
number of shares, the Conversion Price in effect immediately prior thereto
shall be adjusted so that the holder of any Security thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock of
the Company which he would have owned or have been entitled to receive after
the happening of any of the events described above had such Security been converted
immediately prior to the happening of such event.  If any dividend or distribution of the type described in clause
(i) above is not so paid or made, the Conversion Price shall again be adjusted
to the Conversion Price which would then be in effect if such dividend or
distribution had not been declared.  An
adjustment made pursuant to this Section 10.06 shall become effective
immediately after the record date in the case of a dividend and shall become
effective immediately after the effective date in the case of subdivision or
combination.

Section 10.07. 
Adjustment for Rights Issue.  In case the
Company shall issue rights or warrants to all holders of its Common Stock
entitling them (for a period expiring within 45 days after the record date
mentioned below) to subscribe for or purchase Common Stock at a price per share
less than the Current Market Price per share of Common Stock at the record date
for the determination of stockholders entitled to receive such rights or
warrants, the Conversion Price in effect immediately prior thereto shall be
adjusted so that the same shall equal the Conversion Price determined by
multiplying the Conversion Price in effect immediately prior to the date of
issuance of such rights or warrants by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding on the date of issuance of
such rights or warrants plus the number of shares which the aggregate offering
price of the total number of shares so offered would purchase at such Current
Market Price, and of which the denominator shall be the number of shares of
Common Stock outstanding on the date of issuance of such rights or warrants
plus the number of additional shares of Common Stock offered for subscription
or purchase.  Such adjustment shall be
made successively whenever any such rights or warrants are issued, and shall
become effective immediately after the opening of business on the day following
the record date for the determination of the stockholders entitled to receive
such rights or warrants.  To the extent
that shares of Common Stock are not delivered after the expiration of such
rights or warrants, the Conversion Price shall be readjusted to the Conversion
Price which would then be in effect had the adjustments made upon the issuance
of such rights or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered.  If such rights or warrants are not so issued, the Conversion
Price shall again be adjusted to be the Conversion Price which would then be in
effect if such record date for the determination of stockholders entitled to
receive such rights or warrants had not been fixed.  In determining whether any rights or warrants entitle the holders
to subscribe for or purchase shares of Common Stock at less than such Current 

45

 

Market
Price, and in determining the aggregate offering price of such shares of Common
Stock, there shall be taken into account any consideration received by the
Company for such rights or warrants, the value of such consideration, if other
than cash, to be determined by the Board of Directors.

Section 10.08. 
Adjustment for Other Distributions. 
(a) In case the Company shall distribute to all holders of its Common
Stock (excluding any distribution in connection with the liquidation,
dissolution or winding up of the Company, whether voluntary or involuntary) any
shares of any class of capital stock of the Company (other than Common Stock)
or evidences of its indebtedness or assets (other than cash) or rights or
warrants to subscribe for or purchase any of its securities (excluding those
referred to in Section 10.07 hereof) (any of the foregoing hereinafter in this
Section 10.08(a) called the “Distributed Securities”), then, in each
case, the Conversion Price shall be adjusted so that the same shall equal the
Conversion Price determined by multiplying the Conversion Price in effect
immediately prior to the date of such distribution by a fraction of which the
numerator shall be the Current Market Price per share of the Common Stock on
the record date mentioned below less the fair market value on such record date
(as determined by the Board of Directors of the Company, whose determination
shall be conclusive, and described in a certificate filed with the Trustee) of
the Distributed Securities so distributed applicable to one share of Common
Stock, and the denominator shall be the Current Market Price per share of the
Common Stock on such record date.  Such
adjustment shall become effective immediately after the record date for the
determination of stockholders entitled to receive such distribution.  Notwithstanding the foregoing, in the event
the then fair market value (as so determined) of the portion of the Distributed
Securities so distributed applicable to one share of Common Stock is equal to
or greater than the Current Market Price of the Common Stock on the relevant
record date, in lieu of the foregoing adjustment, adequate provision shall be
made so that each Securityholder shall have the right to receive upon
conversion the amount of Distributed Securities such Holder would have received
had such Holder converted each Security on such record date.  In the event that such distribution is not
so paid or made, the Conversion Price shall again be adjusted to the Conversion
Price which would then be in effect if such distribution had not been
declared.  If the Board of Director
determines the fair market value of any distribution for purposes of this
Section 10.08(a) 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 computing the Current Market Price of the Common Stock.

Notwithstanding the
foregoing provisions of this Section 10.08(a), no adjustment shall be made
thereunder for any distribution of Distributed Securities if the Company makes
proper provision so that each Holder of a Security who converts such Security
(or any portion thereof) after the record date for such distribution shall be
entitled to receive upon such conversion, in addition to the 

46

 

shares
of Common Stock issuable upon such conversion, the amount and kind of
Distributed Securities that such Holder would have been entitled to receive if
such Holder had, immediately prior to such record date, converted such Security
into Common Stock, provided that, with respect to any
Distributed Securities that are convertible, exchangeable or exercisable, the
foregoing provision shall only apply to the extent (and so long as) the
Distributed Securities receivable upon conversion of such Security would be
convertible, exchangeable or exercisable, as applicable, without any loss of
rights or privileges for a period of at least 60 days following conversion of
such Security.

(b)   In case the Company shall, by dividend or
otherwise, distribute to all holders of its Common Stock cash (excluding (x)
any quarterly cash dividend on the Common Stock to the extent the aggregate cash
dividend per share of Common Stock in any fiscal quarter does not exceed the
greater of (A) the amount per share of Common Stock of the next preceding
quarterly cash dividend on the Common Stock to the extent such preceding
quarterly dividend did not require any adjustment of the Conversion Price
pursuant to this Section 10.08(b) (as adjusted to reflect subdivisions or
combinations of the Common Stock), and (B) 3.75% of the average of the last
reported sales prices of the Common Stock (determined as provided in the
definition of Current Market Price) during the ten Trading Days next preceding
the date of declaration of such dividend and (y) any dividend or distribution
in connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary), then, in such case, unless the Company
elects to reserve such cash for distribution to the holders of the Securities
upon the conversion of the Securities so that any such holder converting
Securities will receive upon such conversion, in addition to the shares of
Common Stock to which such holder is entitled, the amount of cash which such
holder would have received if such holder had, immediately prior to the record
date for such distribution of cash, converted its Securities into Common Stock,
the Conversion Price shall be decreased so that the same shall equal the
Conversion Price determined by multiplying the Conversion Price in effect
immediately prior to the record date by a fraction of which the numerator shall
be the Current Market Price of the Common Stock on the record date less the
amount of cash so distributed (and not excluded as provided above) applicable
to one share of Common Stock, and the denominator shall be such Current Market
Price of the Common Stock, such decrease to be effective immediately prior to
the opening of business on, the day following the record date; provided,
however, that in the event the portion of the cash so distributed applicable to
one share of Common Stock is equal to or greater than the Current Market Price
of the Common Stock on the record date, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Securityholder shall have the
right to receive upon conversion the amount of cash such holder would have
received had such holder converted each Security on the record date.  If such dividend or distribution is not so
paid or made, the Conversion Price shall again be adjusted to be the Conversion
Price 

47

 

which
would then be in effect if such dividend or distribution had not been
declared.  If any adjustment is required
to be made as set forth in this Section 10.08(b) as a result of a distribution
that is a quarterly dividend, such adjustment shall be based upon the amount by
which such distribution exceeds the amount of the quarterly cash dividend
permitted to be excluded pursuant hereto. 
If an adjustment is required to be made as set forth in this Section
10.08(b) above as a result of a distribution that is not a quarterly dividend,
such adjustment shall be based upon the full amount of the distribution.

(c)   In case a tender or exchange offer made by
the Company or any Subsidiary of the Company for all or any portion of the
Common Stock shall expire and such tender or exchange offer shall involve the
payment by the Company or such Subsidiary of consideration per share of Common
Stock having a fair market value (as determined by the Board of Directors or,
to the extent permitted by applicable law, a duly authorized committee thereof,
whose determination shall be conclusive, and described in a resolution of the
Board of Directors or such duly authorized committee thereof, as the case may
be, at the last time (the “Expiration Time”) tenders or exchanges may
be made pursuant to such tender or exchange offer (as it shall have been
amended)) that exceeds the Current Market Price of the Common Stock on the
Trading Day next succeeding the Expiration Time, the Conversion Price shall be
decreased so that the same shall equal the Conversion Price determined by
multiplying the Conversion Price in effect immediately prior to the Expiration
Time by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding (including any tendered or exchanged shares) on the
Expiration Time multiplied by the Current Market Price of the Common Stock on
the Trading Day next succeeding the Expiration Time, and the denominator shall
be the sum of (x) the fair market value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to
any maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Expiration
Time (the shares deemed so accepted up to any such maximum, being referred to
as the “Purchased
Shares”) and (y) the product of the number of shares of Common Stock
outstanding (less any Purchased Shares) on the Expiration Time and the Current
Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time, such decrease to become effective immediately prior to the
opening of business on the day following the Expiration Time.  In the event that the Company is obligated
to purchase shares pursuant to any such tender or exchange offer, but the
Company is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be effect if such
tender or exchange offer had not been made.

(d)   In case of a tender or exchange offer made by
a Person other than the Company or any Subsidiary for an amount which increases
the offeror’s 

48

 

ownership
of Common Stock to more than 25% of the Common Stock outstanding and shall
involve the payment by such person of consideration per share of Common Stock
having a fair market value (as determined by the Board of Directors, whose
determination shall be conclusive, and described in a resolution of the Board
of Directors) at the last time (the “Offer Expiration Time”) tenders or
exchanges may be made pursuant to such tender or exchange offer (as it shall
have been amended) that exceeds the Current Market Price of the Common Stock on
the Trading Day next succeeding the Offer Expiration Time, and in which, as of
the Offer Expiration Time the Board of Directors is not recommending rejection
of the offer, the Conversion Price shall be decreased so that the same shall
equal the Conversion Price determined by multiplying the Conversion Price in
effect immediately prior to the Offer Expiration Time by a fraction of which
the numerator shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) on the Offer Expiration Time
multiplied by the Current Market Price of the Common Stock on the Trading Day
next succeeding the Offer Expiration Time, and the denominator shall be the sum
of (x) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders based on the acceptance (up to any
maximum specified in the terms of the tender or exchange offer) of all shares
validly tendered or exchanged and not withdrawn as of the Offer Expiration Time
(the shares deemed so accepted, up to any such maximum, being referred to as
the “Accepted
Purchased Shares”) and (y) the product of the number of shares of
Common Stock outstanding (less any Accepted Purchased Shares) on the Offer
Expiration Time and the Current Market Price of the Common Stock on the Trading
Day next succeeding the Expiration Time, such decrease to become effective
immediately prior to the opening of business on the day following the Offer
Expiration Time.  In the event that such
Person is obligated to purchase shares pursuant to any such tender or exchange
offer, but such Person is permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the
Conversion Price shall again be adjusted to be the Conversion Price which would
then be in effect if such tender or exchange offer had not been made.  Notwithstanding the foregoing, the
adjustment described in this Section 10.08(d) shall not be made if as of the
Offer Expiration Time, the offering documents with respect to such offer
disclose a plan or intention to cause the Company to engage in any transaction
described in Article 5.

Section 10.09. 
When Adjustment May be Deferred. 
No adjustment in the Conversion Price need be made unless the
adjustment would require an increase or decrease of at least 1% in the
Conversion Price.  Any adjustments that
are not made shall be carried forward and taken into account in any subsequent
adjustment.

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

49

 

Section 10.10. 
When no Adjustment Required.  No adjustment
need be made for rights to purchase Common Stock pursuant to a Company plan for
reinvestment of dividends or interest.

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

To the extent the Securities
become convertible into cash, assets, property or securities (other than
capital stock of the Company), no adjustment need be made thereafter as to the
cash, assets, property or such securities. 
Interest will not accrue on the cash.

Section 10.11. 
Notice of Adjustment.  Whenever the
Conversion Price is adjusted, the Company shall promptly mail to Securityholders
a notice of the adjustment.  The Company
shall file with the Trustee and the Conversion Agent such notice.  The certificate shall, absent manifest
error, be conclusive evidence that the adjustment is correct.  Neither the Trustee nor any Conversion Agent
shall be under any duty or responsibility with respect to any such certificate
except to exhibit the same to any Holder desiring inspection thereof.

Section 10.12. 
Voluntary Decrease.  The Company may
make such decreases in the Conversion Price, in addition to those required by
Sections 10.06, 10.07 and 10.08, as the Board of Directors considers to be
advisable to avoid or diminish any income tax to holders of Common Stock or
rights to purchase Common Stock resulting from any dividend or distribution of
stock (or rights to acquire stock) or from any event treated as such for income
tax purposes.  To the extent permitted
by applicable law, the Company from time to time may decrease the Conversion
Price by any amount for any period of time if the period is at least 20 days,
the decrease is irrevocable during the period and the Board of Directors shall
have made a determination that such decrease would be in the best interests of
the Company, which determination shall be conclusive.  Whenever the Conversion Price is so decreased, the Company shall
mail to Securityholders and file with the Trustee and the Conversion Agent a
notice of the decrease.  The Company
shall mail the notice at least 15 days before the date the decreased Conversion
Price takes effect.  The notice shall
state the decreased Conversion Price and the period it will be in effect.

Section 10.13.  Notice Of Certain Transactions. 
If:

(a)   the Company makes any distribution or
dividend that would require an adjustment in the Conversion Price pursuant to
Section 10.06, 10.07 or 10.08; or

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

50

 

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

then
the Company shall mail to Securityholders and file with the Trustee and the
Conversion Agent a notice referencing this Section 10.13 and stating the
proposed record date for a dividend or distribution or the proposed effective
date of a subdivision, combination, reclassification, consolidation, merger,
sale, transfer, dissolution, liquidation or winding-up, and if applicable, the
new Conversion Price.  The Company shall
file and mail the notice at least 15 days before such date.  Failure to file or mail the notice or any
defect in it shall not affect the validity of the transaction.  Unless and until the Trustee shall receive a
notice pursuant to this Section 10.13, it shall not be deemed to have knowledge
of any event required to be described in a notice pursuant to this
Section 10.13.

Section 10.14. 
Effect of Reclassification, Consolidation, Merger or Sale.  If any of the following
events occur, namely (i) any reclassification or change of outstanding shares
of Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation, merger or combination of the Company with
another corporation as a result of which holders of Common Stock shall be
entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, or (iii) any sale
or conveyance of the properties and assets of the Company as, or substantially
as, an entirety to any other corporation as a result of which holders of Common
Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock,
then the Company or the successor or purchasing corporation, as the case may
be, shall execute with the Trustee a supplemental indenture providing that each
Security shall be convertible into the kind and amount of shares of stock and
other securities or property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon
conversion of such Securities immediately prior to such reclassification,
change, consolidation, merger, combination, sale or conveyance.  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.

The Company shall cause
notice of the execution of such supplemental indenture to be mailed to each
holder of Securities at his address appearing on the Security register provided
for in Section 2.03 of this Indenture.

The above provisions of this
Section shall similarly apply to successive reclassifications, consolidations,
mergers, combinations, and sales.

If this Section applies,
neither Section 10.06, 10.07 nor 10.08 applies.

51

 

Section 10.15. 
Company Determination Final.  Any
determination that the Company or the Board of Directors must make pursuant to
Section 10.03, 10.06, 10.07, 10.08, 10.09, 10.10, 10.14 or 10.17 is conclusive.

Section 10.16. 
Trustee’s Adjustment Disclaimer. 
The Trustee has no duty to determine when an adjustment under this
Article 10 should be made, how it should be made or what it should be.  The Trustee has no duty to determine whether
a supplemental indenture under Section 10.14 need be entered into or whether
any provisions of any supplemental indenture are correct.  The Trustee shall not be accountable for and
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Securities. 
The Trustee shall not be responsible for the Company’s failure to comply
with this Article 10.  Each Conversion
Agent shall have the same protection under this Section 10.16 as the Trustee.

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

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

Section 10.19. 
Rights Issued in Respect of Common Stock Issued Upon Conversion.  Each share of Common Stock
issued upon conversion of Securities pursuant to this Article 10 shall be
entitled to receive the appropriate number of Rights (as defined below), if
any, and the certificates representing the Common Stock issued upon such
conversion shall bear such legends, if any, in each case as provided by and
subject to the terms of the agreement governing such Rights (the “Rights
Agreement”) as in effect at the time of such conversion.  If the Rights are separated from the Common
Stock in accordance with the provisions of the Rights Agreement such that the
Holders of Securities would thereafter not be entitled to receive any such
Rights in respect to the Common Stock issuable upon conversion of such
Securities, the Conversion Price will be adjusted as provided in Section
10.08(a) on the separation date; provided that if such Rights expire, terminate
or are redeemed by the Company, the Conversion Price shall again be adjusted to
be the Conversion Price which would then be in effect if such separation had
not occurred.  In lieu of any such
adjustment, the Company may amend the Rights Agreement to provide that upon
conversion of the Securities the Holders will receive, in addition to the
Common Stock issuable upon such 

52

 

conversion,
the Rights which would have attached to such shares of Common Stock if the
Rights had not become separated from the Common Stock pursuant to the
provisions of the Rights Agreement.

Rights or warrants
distributed by the Company to all holders of Common Stock entitling the holders
thereof to subscribe for or purchase shares of the Company’s capital stock
(either initially or under certain circumstances), which rights or warrants,
until the occurrence of a specified event or events (“Trigger Event”):

(a)   are deemed to be transferred with such shares
of Common Stock,

(b)   are not exercisable, and

(c)   are also issued in respect of future
issuances of Common Stock,

(“Rights”)
shall not be deemed distributed for purposes of Section 10.08(a) until the
occurrence of the earliest Trigger Event. 
In addition, in the event of any distribution of rights or warrants, or
any Trigger Event with respect thereto, that shall have resulted in an
adjustment to the Conversion Price under Section 10.08(a), (1) in the case of
any such rights or warrants which shall all have been redeemed or repurchased
without exercise by any holders thereof, the Conversion Price 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 of Common Stock with respect to such rights or warrants (assuming such
holder had retained such rights or warrants), made to all holders of Common
Stock as of the date of such redemption or repurchase, and (2) in the case of
any such rights or warrants all of which shall have expired without exercise by
any holder thereof, the Conversion Price shall be readjusted as if such
issuance had not occurred.

Section 10.20. 
General Considerations.  Whenever
successive adjustments to the Conversion Price are called for pursuant to this
Article 10, such adjustments shall be made to the Current Market Price as may
be necessary or appropriate to effectuate the intent of this Article and to avoid
unjust or inequitable results as determined in good faith by the Board of
Directors.

Silicon Graphics, Inc., a
Delaware corporation, promises to pay to or registered assigns, the principal
amount of_____________ Dollars ($) on July 1, 2009 and to pay interest
thereon from  [the date after expiration
of the exchange offer], 2003 or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, semi-annually on
January 1 and July 1 in each year, commencing January 1, 2004,
at the rate of 6.50% per annum until the principal hereof is paid or made
available for payment.  The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the
December 15 or June 15 (whether or not a Business Day), as the case
may be, next preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in
whose name this Security (or one or more Predecessor Securities) is registered
at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
Holders of Securities not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not

inconsistent
with the requirements of any securities exchange or other market on which the
Securities may be listed, and upon such notice as may be required by such
exchange or market, all as more fully provided in said Indenture.  Payment of the principal of (and premium, if
any) and interest on this Security will be made at the Corporate Trust Office
or the office or agency of the Company maintained for that purposes in the
Borough of Manhattan, The City of New York, New York in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that at the option of
the Company payment of interest may be made by check mailed to the address of,
or by wire transfer to the account of, the Person entitled thereto as such
address shall appear in the Security Register.

Additional provisions of

1.             Interest

This Security shall bear
interest at 6.50% per annum in the manner set forth in the Indenture and the
face of this Security.  In the event
that principal hereof or any portion of such principal is not paid when due
(whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the
date set for payment of the Redemption Price pursuant to paragraph 5 hereof, upon
the date set for payment of a Fundamental Change Redemption Price pursuant to
paragraph 6 hereof or upon the Stated Maturity of this Security), then in each
such case the overdue amount shall bear interest at the rate of 6.50% per
annum, compounded semiannually (to the extent that the payment of such interest
shall be legally enforceable), which interest shall accrue from the date such
overdue amount was due to the date payment of such amount, including interest
thereon, has been made or duly provided for. 
All such interest shall be payable on demand.

2.             Method
of Payment

Subject to the terms and
conditions of the Indenture, the Company will make payments in respect of the
Securities to the persons who are registered Holders of Securities at the close
of business on the Redemption Date, Fundamental Change Repurchase Date or
Stated Maturity, as the case may be. 
Holders must surrender Securities to a Paying Agent to collect such
payments in respect of the Securities. 
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.  However, the Company may make
such cash payments by check mailed to the address of, or by wire transfer to
the account of, the person entitled to such payment.

3.             Paying
Agent, Conversion Agent and Registrar

Initially, U.S. Bank
National Association, a national banking association (the “Trustee”), will act as Paying
Agent, Conversion Agent and Registrar. 
The Company may appoint and change any Paying Agent, Conversion Agent,
Registrar or co-registrar without notice, other than notice to the
Trustee.  The Company or any of its
Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion
Agent, Registrar or co-registrar.

4.             Indenture

The Company issued the
Securities under an Indenture dated as of July __, 2003 (the “Indenture”),
between the Company and the Trustee. 
Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture.  The
Securities are subject to all such terms, and Securityholders are referred to
the Indenture for a statement of those terms.

The Securities are general
unsecured obligations of the Company limited to $78,000,000 aggregate principal
amount (subject to Sections 2.02 and 2.07 of the Indenture).

5.             Redemption
at the Option of the Company

Prior to the second
anniversary of the original issuance of the Securities, the Securities will not
be redeemable at the option of the Company. 
Beginning on the second anniversary of the original issuance of the
Securities, the Company may redeem the Securities for cash as a whole at any
time, or from time to time in part, upon not less than 10 days’ nor more than
60 days’ notice at the a price equal to 100% of the principal amount (the “Redemption
Price”) thereof, together with accrued and unpaid interest to, but
excluding, the Redemption Date, provided that during the year beginning on the
first anniversary of the original issuance of the Securities, the Company may
only redeem the Securities if the Closing Price of the Company’s Common Stock
has been at least 150% of the then-applicable Conversion Price for the 20
consecutive Trading Days ending two Trading Days prior to the notice of
redemption.

If
any Redemption Date is an Interest Payment Date, then the interest payable on
such date shall be paid to the Holder of the Security on the next preceding
Regular Record Date.  No Securities may
be redeemed by the Company if an Event of Default with respect to the payment
of interest on the Securities has occurred and is continuing.

No sinking fund is provided
for the Securities.

Notice of redemption at the
option of the Company will be mailed at least 30 days but not more than 60 days
before the Redemption Date to each Holder of Securities to be redeemed at the
Holder’s registered address.  If money
sufficient to pay the Redemption Price, together with accrued interest to, but
excluding, the Redemption Date, of all Securities (or portions thereof) to be
redeemed on the Redemption Date is deposited with the Paying Agent prior to or
on the Redemption Date, on and after such date interest ceases to accrue on
such Securities or portions thereof. 
Securities in denominations larger than $1,000 of principal amount may
be redeemed in part but only in multiples of $1,000 of principal amount.

A-5

 

6.             Redemption
at the Option of the Holder Upon a Fundamental Change

(a)           At the option of the Holder and subject
to the terms and conditions of the Indenture, the Company shall become
obligated to redeem the Securities held by such Holder on the date (the “Fundamental
Change Repurchase Date”) (or if such date is not a Business Day, the
next succeeding Business Day) that is 45 days after the date of the Company’s
notice of such Fundamental Change (as defined in the Indenture) occurring on or
prior to July 1, 2009 at 100% of the principal amount.  In each case, the Company shall also pay
accrued but unpaid interest, if any, on such Securities to, but excluding, the
Fundamental Change Repurchase Date; provided that if such Fundamental Change
Repurchase Date is an Interest Payment Date, then the interest payable on such
date shall be paid to the Holder of the Security on the next preceding Regular
Record Date.  Securities in
denominations larger than $1,000 of principal amount may be redeemed in part in
connection with a Fundamental Change, but only in multiples of $1,000 of principal
amount.

(b)           Holders have the right to withdraw
any Fundamental Change Redemption Notice by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the
Indenture.

(c)           If cash sufficient to pay the
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date, of all Securities or
portions thereof to be purchased as of the Fundamental Change Repurchase Date
is deposited with the Paying Agent on or prior to the Fundamental Change Repurchase
Date, interest ceases to accrue on such Securities (or portions thereof) on and
after the Fundamental Change Repurchase Date, and the Holder thereof shall have
no other rights as such (other than the right to receive the Fundamental Change
Redemption Price, together with accrued interest to, but excluding, the
Fundamental Change Repurchase Date, upon surrender of such Security).

7.             Conversion

Subject to the next two
succeeding sentences, a Holder of a Security may convert it into Common Stock
of the Company at any time after issuance and before the close of business on
July 1, 2009.  If the Security is called
for redemption, the Holder may convert it at any time before the close of the
last Trading Day prior to the Redemption Date. 
In the event the Security is surrendered during the period from the
close of business on any Regular Record Date next preceding any Interest
Payment Date to the close of business on the Trading Day immediately preceding
the next succeeding Interest Payment Date (except in the case of Security to be
redeemed within such period), such Securities must be accompanied by payment in
New York Clearing House funds or other funds acceptable to the Company of an
amount equal to the interest payable on 

A-6

 

such
Interest Payment Date on the principal amount of this Security then being
converted.  Subject to the aforesaid
requirement for payment and, in the case of a conversion after the Regular
Record Date next preceding any Interest Payment Date and on or before such
Interest Payment Date, to the right of the Holder of this Security (or any
Predecessor Security) of record at such Regular Record Date to receive an
installment of interest payable on such Interest Payment Date (except in the case
of Securities whose Maturity is prior to such Interest Payment Date), no
payment or adjustment is to be made on conversion for interest accrued hereon
or for dividends on the Common Stock issued on conversion.  A Security in respect of which a Holder has
delivered a notice of exercise of the option to redeem such Security in the
event of a Fundamental Change may be converted only if the notice of exercise
is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Price
is $1.85 per share of Common Stock, subject to adjustment or reduction in
certain events described in Sections 2 and 10 of the Indenture.  The Company will deliver cash or a check in
lieu of any fractional share of Common Stock.

To convert a Security a
Holder must (1) complete and manually sign the conversion notice on the back of
the Security (or complete and manually sign a facsimile of such notice) and
deliver such notice to the Conversion Agent, (2) surrender the Security to a
Conversion Agent, (3) furnish appropriate endorsements and transfer documents
if required by the Conversion Agent, the Company or the Trustee and (4) pay any
transfer or similar tax, if required.

A Holder may convert a
portion of a Security if the principal amount of such portion is $1,000 or a
multiple of $1,000.  No payment or
adjustment will be made for dividends on the Common Stock except as provided in
the indenture.

The Conversion Price is
subject to adjustment or reduction as provided in the Indenture.  In addition, in the case of (i) any
reclassification of the Common Stock, or (ii) a consolidation or merger
involving the Company or a sale or
conveyance to another corporation of the property and assets of the
Company as an entirety (or substantially as an entirety), in each case as a result
of which holders of Common Stock shall be
entitled to receive stock, securities, other property or assets
(including cash) with respect to or in exchange for such Common Stock, as set
forth in the Indenture, or upon certain distributions described in the
Indenture, the right to convert a Security into Common Stock may be changed; as
set forth in the Indenture, into a right to convert it into securities, cash or
other assets of the Company or another person.

A-7

 

8.             Conversion
Arrangement on Call for Redemption

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

9.             Denominations;
Transfer; Exchange

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

10.          Persons
Deemed Owners

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

11.          Unclaimed
Money or Securities

The Trustee and the Paying
Agent shall return to the Company upon written request any money or securities
held by them for the payment of any amount with respect to the Securities that
remains unclaimed for two years, provided, however, that the Trustee or such
Paying Agent, before being required to make any such return, shall at the
expense of the Company cause to be published once in a newspaper of general
circulation in The City of New York or mail to each such Holder notice that
such money or securities remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing, any unclaimed money or securities then remaining will be returned
to the Company.  After return to the
Company, Holders entitled to the money or securities must look to the Company
for payment 

A-8

 

as
general creditors unless an applicable abandoned property law designates
another person.

12.          Amendment;
Waiver

Subject to certain
exceptions set forth in the Indenture, (i) the Indenture or the Securities may
be amended with the written consent of the Holders of at least a majority in
aggregate principal amount of the Securities at the time outstanding and (ii)
certain defaults or noncompliance with certain provisions may be waived with
the written consent of the Holders of a majority in aggregate principal amount
of the Securities at the time outstanding. 
Subject to certain exceptions set forth in the Indenture, without the
consent of any Securityholder, the Company and the Trustee may amend the
Indenture or the Securities to cure any ambiguity, defect or inconsistency, or
to comply with Article 5 or Section 10.14 of the Indenture, to provide for
uncertificated Securities in addition to or in place of certificated Securities
or to make any change that does not adversely affect the rights of any
Securityholder or to comply with any requirement of the SEC in connection with
the qualification of the Indenture under the TIA.

13.          Defaults
and Remedies

Under the Indenture, Events
of Default include (i) default in payment of the principal amount, Redemption
Price or Fundamental Change Redemption Price, as the case may be, in respect of
the Securities when the same becomes due and payable; (ii) default for 30 days
in the payment of any installment of interest on the Securities; (iii) failure
by the Company to comply with other agreements in the Indenture or the
Securities, subject to notice and lapse of time; provided, that the Company’s
failure to comply with its agreement set forth in Section 2.15(a) or (b) shall
not constitute an Event of Default under the Securities or under the Indenture
and thus, Holders shall not be entitled to exercise the remedies set forth
herein or in Article 6 of the Indenture, but shall be limited to the remedy set
forth in Section 2.15 of the Indenture; (iv) an event of default under the
Secured Credit Facility, the Old Notes Indenture or the New Indenture shall
have occurred that results in the principal amount of and accrued interest on
that debt becoming immediately due and payable, and (v) certain events of
bankruptcy or insolvency.  If an Event
of Default occurs and is continuing, the Trustee, or the Holders of at least
25% in aggregate principal amount of the Securities at the time outstanding,
may declare all the Securities to be due and payable immediately.  Certain events of bankruptcy or insolvency
are Events of Default which will result in the Securities being declared due
and payable immediately upon the occurrence of such Events of Default.

Securityholders may not
enforce the Indenture or the Securities except as provided in the
Indenture.  The Trustee may refuse to
enforce the Indenture or the Securities unless it receives reasonable indemnity
or security.  Subject to certain 

A-9

 

limitations,
Holders of a majority in aggregate principal amount of the Securities at the
time outstanding may direct the Trustee in its exercise of any trust or
power.  The Trustee may withhold from
Securityholders notice of any continuing Default (except a Default in payment
of amounts specified in clause (i) or (ii) above) if it determines that
withholding notice is in their interests.

14.          Trustee
Dealings with the Company

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

15.          No
Recourse Against Others

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

16.          Authentication

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

17.          Abbreviations

Customary abbreviations may
be used in the name of a Securityholder or an assignee, such as TEN COM
(=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint
tenants with right of survivorship and not as tenants in common), CUST
