require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent shall have no further liability for such
money. If the Company acts as Paying Agent, it shall segregate and hold as a
separate trust fund all money held by it as Paying Agent.

    


    Section 2.5 Securityholder
Lists.

    


    The
Trustee shall preserve in as current a form as is reasonably practicable the

available to cover the payment of interest in shares; (2) the shares of Common
Stock to be issued shall not require registration with, or approval of, any
governmental authority under any state law or any other federal law before such

Conversion Date, Mandatory Conversion Date or Maturity Date, as applicable; and
(3) the shares of Common Stock to be issued will, upon issuance, be duly and

the Holder’s prime broker with the DTC through its Deposit Withdrawal Agent

    Section 2.8 Mutilated,
Destroyed, Lost and Stolen Securities.

    


    If any
mutilated Security is surrendered to the Trustee, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security
and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

    


    If there
shall be delivered to the Company and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Security and (ii) such
security or indemnity as may be required by them to save each of them and any
agent of either of them harmless, then, in the absence of notice to the Company
or the Trustee that such Security has been acquired by a protected purchaser,
the Company shall execute and upon its request the Trustee shall authenticate
and make available for delivery, in lieu of any such destroyed, lost or stolen
Security, a new Security and of like tenor and principal amount and 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, the Company in its discretion may, instead of issuing a
new Security, pay such Security.

    


    Upon the
issuance of any new Security 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 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 the benefits of
this Indenture equally and proportionately with any and all other Securities
duly issued hereunder.

    The

lawful) all other rights and remedies with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities.

    


    Section 2.9 Outstanding
Securities.

    


    If the
Paying Agent (other than the Company) holds on the Maturity Date, money
sufficient to pay the principal amount with respect to all Securities to be paid
upon maturity plus, if applicable, accrued and unpaid interest, if any, payable
as herein provided upon maturity, then (unless there shall be a Default in the
payment of such principal amount, or of such accrued and unpaid interest),
except as otherwise provided herein, on and after such date such Securities
shall be deemed to be no longer outstanding, interest on such Securities shall
cease to accrue, and such Securities shall be deemed paid whether or not such
Securities are delivered to the Paying Agent. Thereafter, all rights of the
Holders of such Securities shall terminate with respect to such Securities,
other than the right to receive the principal amount plus, if applicable, such
accrued and unpaid interest, in accordance with this Indenture.

    


    If a
Security is converted in accordance with ARTICLE IX, then, from and after the
time of such conversion on the Conversion Date, such Security shall cease to be
outstanding, and interest, if any, shall cease to accrue on such Security unless
there shall be a Default in the payment or delivery of the consideration payable
hereunder upon such conversion.

    


    Section 2.10 Cancellation.

The Global Securities initially shall (i) be registered in the name of
the Depository for the Securities or the nominee of such Depository, (ii) be
delivered to the Trustee as custodian for such Depository and (iii) bear legends
as required hereby. Members of, or participants in, the Depository for the
Securities (“Participants”) shall have no rights under this Indenture with
respect to any Global Security held on their behalf by such Depository, or the
Trustee as its custodian, or under the Global Security, and such Depository may
be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of the Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
such Depository or impair, as between such Depository and Participants, the
operation of customary practices governing the exercise of the rights of a
Holder of any Security.

    


    2.13.2 Transfer and Exchange.
Notwithstanding any provisions to the contrary contained in Section 2.6
of the Indenture and in addition thereto, any Global Security shall be
exchangeable pursuant to Section 2.6 of the Indenture for Securities registered
in the names of Holders other than the Depository for such Security or its
nominee only if (i) such Depository notifies the Company that it is unwilling or
unable to continue as Depository for such Global Security or if at any time such
Depository ceases to be a clearing agency registered under the Exchange Act,
and, in either case, the Company fails to appoint a successor Depository within
90 days of such event, (ii) the Company executes and delivers to the Trustee an
Officers’ Certificate to the effect that such Global Security shall be so
exchangeable or (iii) an Event of Default with respect to the Securities
represented by such Global Security shall have happened and be continuing. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Securities registered in such names as the Depository shall
direct in writing in an aggregate principal amount equal to the principal amount
of the Global Security with like tenor and terms.

    Except as
provided in this Section 2.13.2, a Global Security may not be transferred except
as a whole by the Depository with respect to such Global Security to a nominee
of such Depository, by a nominee of such Depository to such Depository or
another nominee of such Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such a successor Depository.

    


    2.13.3 Legend. Unless
otherwise provided pursuant to Section 2.2, any Global Security issued hereunder
shall bear a legend in substantially the following form:

    


    “This
Security is a Global Security within the meaning of the Indenture hereinafter
referred to and is registered in the name of the Depository or a nominee of the
Depository. This Security is exchangeable for Securities registered in the name
of a person other than the Depository or its nominee only in the limited
circumstances described in the Indenture, and may not be transferred except as a
whole by the Depository to a nominee of the Depository, by a nominee of the
Depository to the Depository or another nominee of the Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such a
successor Depository.”

    


    2.13.4 Acts of Holders. The
Depository, as a Holder, may appoint agents and otherwise authorize participants
to give or take any request, demand, authorization, direction, notice, consent,
waiver or other action which a Holder is entitled to give or take under the
Indenture.

    


    2.13.5 Payments.
Notwithstanding the other provisions of this Indenture, unless otherwise
specified as contemplated by Section 2.2, payment of the principal of and
interest, if any, on any Global Security shall be made to the Holder
thereof.

    


    2.13.6 Consents, Declaration and
Directions. Except as provided in Section 2.13.5, the Company, the
Trustee and any Agent shall treat a person as the Holder of such principal
amount of outstanding Securities represented by a Global Security as shall be
specified in a written statement of the Depository with respect to such Global
Security, for purposes of obtaining any consents, declarations, waivers or
directions required to be given by the Holders pursuant to this
Indenture.

    


    Section 2.14 CUSIP
Numbers.

    


    The
Company in issuing the Securities may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption
as a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other elements of identification printed on
the Securities, and any such redemption shall not be affected by any defect in
or omission of such CUSIP numbers. The Company shall promptly notify the Trustee
of any change in the CUSIP numbers.

    


    Section 2.15 Deposit
of Moneys.

    


    Prior to

Date, the Company shall have deposited with a Paying Agent (other than the
Company) money, in funds immediately available on such date, sufficient to make
cash payments, if any, due on such interest payment date, if applicable, or, the
Maturity Date, as the case may be, in a timely manner which permits the Paying
Agent to remit payment to the Holders on such interest payment date, if
applicable, or, the Maturity Date, as the case may be.

    


    Section 2.16 Ranking.

    


    The
Securities will be secured on a second-priority lien basis by all of the
Company’s assets, subordinated to existing and future Senior Debt, senior to any
existing and future Indebtedness that by its terms ranks junior to the
Securities, pari-passu with the Company’s other existing and future Indebtedness
except in the case of existing and future unsecured Indebtedness to the extent
of the value of assets securing the Securities remaining after application to
any Senior Debt.

Securities.

    


    The
Company may, without the consent of the Holders and notwithstanding Section 2.1
and Section 2.2 hereof, reopen the Securities and issue additional Securities
hereunder with the same terms and conditions (except for any difference in the
issue price therefor and interest accrued prior to the date of issuance thereof)
and with the same CUSIP number as the Securities initially issued hereunder in
an aggregate principal amount of up to $[___], which will form the same series
with the Securities initially issued hereunder, provided that such additional
Securities constitute the same issue as the Securities initially issued
hereunder for U.S. federal income tax purposes. The Securities initially issued
hereunder and any such additional Securities would rank equally and ratably and
would be treated as a single series of debt securities for all purposes under
the Indenture.

of Principal and Interest.

    


    3.1.1 The Company shall pay
all amounts due with respect to the Securities on the dates and in the manner
provided in the Securities. All such amounts shall be considered paid on the

sufficient to pay the amount then due with respect to the Securities (unless
there shall be a Default in the payment of such amounts to the respective
Holder(s)).

    


    3.1.2 The Company shall pay,

York, where Securities may be surrendered for registration of transfer or
exchange, payment or conversion and where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served. The
Corporate Trust Office will initially serve as the office or agency for such
purposes. The Company will give prompt written notice to the Trustee of any
change in the location of such 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 of any change in the location thereof, such
presentations, surrenders, notices and demands may continue to be made or served
at the Corporate Trust Office of the Trustee.

    


    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 [___] for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

such report as the SEC may from time to time by rules and regulations prescribe)
the Company is required to file with the SEC pursuant to Section 13 or 15(d) of
the Exchange Act; provided, however, that the Company shall not be required to
deliver to the Trustee any material for which the Company has sought and
received confidential treatment by the SEC; provided further, each such report
will be deemed to be so delivered to the Trustee at the time such report is
filed with the SEC through the SEC’s EDGAR database.

not accept such filing, file with the SEC in accordance with rules and
regulations prescribed from time to time by the SEC) and, upon request, to each
Holder, no later than the date the Company would have been required to file the
same with the SEC, the reports the Company would have been required to file with
the SEC pursuant to Section 13 or 15(d) of the Exchange Act (after giving

registered on a national securities exchange and were subject to the reporting
requirements of such sections. The Company shall also deliver to the Trustee
copies of the Company’s annual report to stockholders, containing audited
financial statements, and any other financial reports which the Company
furnishes to its stockholders. The Company also shall comply with the other
provisions of TIA § 314(a). Delivery of such reports, information and documents
to the Trustee is for informational purposes only, and the Trustee’s receipt
thereof shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers’ Certificates).

    


    Section 3.4 Compliance

    The
Company shall deliver to the Trustee, within 90 days after the end of each
fiscal year of the Company, or, if earlier, the date the Company is, or would
be, required to file with the SEC the Company’s annual report (whether on Form
10-K under the Exchange Act or another appropriate form) for such fiscal year,

any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, extension or usury law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture or the Securities; and the Company (to the extent
it may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not, by resort to any such law, 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
has been enacted.

Existence.

to ARTICLE IV, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and the
rights (charter and statutory), licenses and franchises of the Company; provided, however, that the
Company shall not be required to preserve any such right, license or franchise,
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company taken as a whole
and that the loss thereof is not adverse in any material respect to the
Holders.

    


    Section 3.7 Taxes.

    


    The
Company shall pay prior to delinquency all taxes, assessments and governmental
levies, except as contested in good faith and by appropriate

“successor person”), and may not permit any person to merge into, or convey,

of Maturity; Rescission and Annulment.

    


    If an

to the Company (and to the Trustee if given by Holders), and upon any such
declaration such principal amount and accrued and unpaid interest, if any, shall
become immediately due and payable. If an Event of Default specified in Sections
5.1(g) or (h) with respect to the Company shall occur, the principal amount of
and accrued and unpaid interest, if any, on all outstanding Securities shall
ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

    


    At any
time after such a declaration of acceleration with respect to the Securities has
been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in principal amount of the outstanding Securities, by written notice
to the Company and the Trustee, may rescind and annul such declaration and its
consequences if:

pay

    


    (i) all
overdue interest, if any, on all Securities,

principal of any Securities which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate or rates prescribed
therefor in such Securities,

    


    (iii) to
the extent that payment of such interest is lawful, interest upon any overdue
principal and overdue interest at the rate or rates prescribed therefor in such
Securities, and

    


    (iv) all
sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel;
and

    


    (b) all
Events of Default with respect to Securities, other than the non-payment of the
principal of Securities which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section
5.13.

    


    No such
rescission shall affect any subsequent Default or impair any right consequent
thereon.

    


    Section 5.3 Collection
of Indebtedness and Suits for Enforcement by Trustee.

    


    The
Company covenants that if:

    


    (a)
default is made in the payment of any interest on any Security when such
interest becomes due and payable and such default continues for a period of 30
days, or

    


    (b)
default is made in the payment of principal of any Security at the Maturity
thereof, then, subject to the Intercreditor Agreement, the Company will, upon
demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal and interest and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal or any overdue interest,
at the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel.


    
      
         


      

      
        16

        
          

        

      

      
         


      

    

    


    If the
Company fails to pay such amounts forthwith upon such demand, the Trustee, in
its own name and as trustee of an express trust, subject to any restrictions in
the Intercreditor Agreement, may institute a judicial proceeding for the
collection of the sums so due and unpaid, may prosecute such proceeding to
judgment or final decree and may enforce the same against the Company or any
other obligor upon such Securities and collect the moneys adjudged or deemed to
be payable in the manner provided by law out of the property of the Company or
any other obligor upon such Securities, wherever situated.

    


    If an
Event of Default with respect to any Securities occurs and is continuing,
subject to any restrictions in the Intercreditor Agreement, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or the
Security Documents or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

    


    Section 5.4 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, subject
to the restrictions in the Intercreditor Agreement, the Trustee (irrespective of
whether the principal 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 overdue principal
or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

    


    (a) to
file and prove a claim for the whole amount of principal and interest owing and
unpaid in respect of the Securities 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 other similar official in any such judicial

Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to 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 6.7.

    


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

such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

collected by the Trustee pursuant to this Article shall be applied in the

partially paid and upon surrender thereof if fully paid:

    


    First: To

    Second:
To the payment of the amounts then due and unpaid for principal of and interest
on the Securities in respect of which or for the benefit of which such money has

on Suits.

    


    No Holder
of any Security shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, except in compliance with any
restrictions in the Intercreditor Agreement and unless

    


    (a) such
Holder has previously given written notice to the Trustee of a continuing Event
of Default with respect to the Securities;

    


    (b) the
Holders of not less than 25% in principal amount of the outstanding Securities
shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default in its own name as Trustee
hereunder;

    


    (c) such
Holder or Holders have offered to the Trustee reasonable indemnity against the
losses, expenses or liabilities to be incurred in compliance with such
request;

    


    (d) the
Trustee for 60 days after its receipt of such notice, request and offer of
indemnity has failed to institute any such proceeding; and

    


    (e) no
direction inconsistent with such written request has been given to the Trustee
during such 60 day period by the Holders of a majority in principal amount of
the outstanding Securities;

    


    it being
understood and intended that no one or more of such Holders shall have any right
in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such
Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all such
Holders.

    


    Section 5.8 Unconditional
Right of Holders to Receive Principal and Interest and to
Convert Securities.

    


    Notwithstanding
any other provision in this Indenture, the Holder of any Security shall have the

of and interest, if any, on such Security on the Stated Maturity or Stated
Maturities expressed in such Security, to convert any Security into shares of
Common Stock in accordance with the terms of such Security and, subject to the
Intercreditor Agreement, to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

    


    Section 5.9 Restoration
of Rights and Remedies.

    


    If the
Trustee or any Holder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Holders shall be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

    


    Section 5.10 Rights
and Remedies Cumulative.

    


    Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in Section 2.8, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.


    
      
         


      

      
        18

        
          

        

      

      
         


      

    

    


    Section 5.11 Delay or
Omission Not Waiver.

    


    No delay
or omission of the Trustee or of any Holder of any Securities to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may
be.

    


    Section 5.12 Control
by Holders.

    


    The
Holders of a majority in principal amount of the outstanding Securities shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, with respect to the Securities, provided
that:

    


    (a) such
direction shall not be in conflict with any rule of law or with this Indenture
or the Intercreditor Agreement,

    


    (b) the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, and

    


    (c)
subject to the provisions of Section 6.1, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall, by a
Responsible Officer of the Trustee, determine that the proceeding so directed
would involve the Trustee in personal liability.

    


    Section 5.13 Waiver of
Past Defaults.

    


    Subject
to Section 5.2, the Holders of not less than a majority in principal amount of
the outstanding Securities may on behalf of the Holders of all the Securities
waive any past Default hereunder with respect the Securities and its
consequences, except (a) a Default in the payment of the principal of or
interest on any Security, (b) a Default with respect to a Holder’s right to
convert Securities, or (c) a Default with respect to any covenant the amendment
of which would require the consent of each Holder (provided, however, that the
Holders of [a majority] in principal amount of the outstanding Securities may
rescind an acceleration and its consequences, including any related payment
default that resulted from such acceleration). Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

    


    Section 5.14 Undertaking
for Costs.

    


    All
parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the outstanding Securities, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of or interest on any
Security on or after the Stated Maturity or Stated Maturities expressed in such
Security (or, in the case of redemption, on the redemption
date).

    TRUSTEE

    


    Section 6.1 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 their 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:

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 Officers’ Certificates or Opinions of Counsel furnished to the
Trustee and conforming to the requirements of this Indenture; however, in the case
of any such Officers’ Certificates or Opinions of Counsel which by any
provisions hereof are specifically required to be furnished to the Trustee, the
Trustee shall examine such Officers’ Certificates and Opinions of Counsel 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 does not limit the effect of paragraph (b) of this
Section.

    


    (ii) The
Trustee shall not be liable for any error of judgment made in good faith by a

ascertaining the pertinent facts.

    


    (iii) The
Trustee shall not be liable with respect to any action taken, suffered or
omitted to be taken by it with respect to Securities in good faith in accordance
with the direction of the Holders of a majority in principal amount of the
outstanding Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture with respect to the
Securities.

    


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

    (h) No
provision of this Indenture shall require the Trustee to risk its own funds or
otherwise incur any financial liability in the performance of any of its duties,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk is not reasonably assured to it.

    


    (i) The
Paying Agent, the Registrar and any authenticating agent shall be entitled to
the protections and immunities as are set forth in paragraphs (a), (b) and (c)
of this Section with respect to the Trustee; provided that such

Trustee.

    


    (a) The
Trustee may rely on and shall be protected in acting or refraining from acting
upon 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)

reliance thereon.

Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders

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 an Affiliate with the
same rights it would have if it were not Trustee. Any Agent may do the same with
like rights. The Trustee is also subject to Sections 6.10 and 6.11.

    


    Section 6.4 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, and it shall not be responsible for any statement
in the Securities other than its authentication.

    


    Section 6.5 Notice of
Defaults.

    


    If a
Default or Event of Default occurs and is continuing with respect to the
Securities and if it is known to a Responsible Officer of the Trustee, the
Trustee shall mail to each Securityholder of the Securities notice of a Default
or Event of Default within 30 days after it occurs or, if later, after a
Responsible Officer of the Trustee has knowledge of such Default or Event of
Default. Except in the case of a Default or Event of Default in payment of
principal of or interest on any Security, the Trustee may withhold the notice if
and so long as its corporate trust committee or a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

the extent required under, TIA Section 313.

    A copy of
each report at the time of its mailing to Securityholders shall be filed with
the SEC and each stock exchange on which the Securities are listed. The Company
shall promptly notify the Trustee when Securities are listed on any stock
exchange.

    


    Section 6.7 Compensation
and Indemnity.

    


    The
Company shall pay to the Trustee from time to time reasonable compensation for
its services. The Trustee’s compensation shall not be limited by any law on

or Agent. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any settlement made without its consent, which consent shall not be
unreasonably withheld. This indemnification shall apply to officers, directors,
employees, shareholders and agents of the Trustee.

    


    The
Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee or by any officer, director, employee,
shareholder or agent of the Trustee through negligence or bad
faith.

Securities.

    


    When the
Trustee incurs expenses or renders services after an Event of Default specified
in Section 5.1(g) or Section 5.1(h) occurs, the expenses and the compensation

Bankruptcy Law.

    


    Section 6.8 Replacement
of Trustee.

    


    A
resignation or removal of the Trustee and appointment of a successor Trustee
shall become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section.

    


    The
Trustee may resign with respect to the Securities by so notifying the Company.
The Holders of a majority in principal amount of the Securities may remove the
Trustee by so notifying the Trustee and the Company. The Company may remove the

Trustee resigns or is removed or if a vacancy exists in the office of Trustee
for any reason, the Company shall promptly appoint a successor Trustee. Within
one year after the successor Trustee takes office, the Holders of a majority in
principal amount of the then outstanding Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.

successor Trustee with respect to the Securities does not take office within 60
days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in principal amount of the Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.


    
      
         


      

      
        22

        
          

        

      

      
         


      

    

    


    If the
Trustee with respect to the Securities fails to comply with Section 6.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Immediately after that, the retiring
Trustee shall transfer all property held by it as Trustee to the successor
Trustee subject to the lien provided for in Section 6.7, 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 with respect
to the Securities for which it is acting as Trustee under this Indenture. A
successor Trustee shall mail a notice of its succession to each Securityholder.
Notwithstanding replacement of the Trustee pursuant to this Section 6.8, the
Company’s obligations under Section 6.7 hereof shall continue for the benefit of
the retiring trustee with respect to expenses and liabilities incurred by it
prior to such replacement.

    


    Section 6.9 Successor
Trustee by Merger, Etc.

Trustee consolidates with, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor
Trustee.

    


    Section 6.10 Eligibility;
Disqualification.

Indenture shall always have a Trustee who satisfies the requirements of TIA

annual report of condition. The Trustee shall comply with TIA Section
310(b).

    


    Section 6.11 Preferential
Collection of Claims Against Company.

    


    The
Trustee is subject to TIA Section 311(a), excluding any creditor relationship

held by them for the payment of principal and interest that remains unclaimed
for two years. Thereafter, the Trustee and Paying Agent may withhold paying any
such money to the Company until they publish in a newspaper of general
circulation in the City of New York, or mail to each Holder, a notice stating
that the money will be paid to the Company if unclaimed after a date no less
than 30 days from the publication or mailing. After that, Securityholders
entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another person, and all
liability of the Trustee and the Paying agent with respect to the money will
cease.

    


    Section 7.4 Reinstatement.

    


    If the
Trustee or Paying Agent is unable to apply any money or U.S. Government
Obligations in accordance with Section 6.1, by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 6.1, until such
time as the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 6.1; provided, however, that
if the Company makes any payment of principal of, premium, if any, or interest
on any Securities because of reinstatement of its obligations, the Company shall
be subrogated to the rights of the holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent.

        24

        
          

        

      

      
         


      

    

    


    In
addition, the Company and the Trustee, subject to any restrictions in the
Intercreditor Agreement, may enter into a supplemental indenture without the
consent of Holders of the Securities to cure any ambiguity, defect, omission or
inconsistency in this Indenture in a manner that does not, individually or in
the aggregate with all other modifications made or to be made to the Indenture,
adversely affect the rights of any Holder.

    


    Section 8.2 With
Consent of Holders.

    


    The
Company, with the consent of the Trustee, subject to any restrictions in the
Intercreditor Agreement, may amend or supplement this Indenture or the
Securities without notice to any Securityholder but with the written consent of
the Holders of at least a majority in aggregate principal amount of the
outstanding Securities. Subject to Section 5.2, Section 5.8 and Section 5.13,
the Holders of a majority in aggregate principal amount of the outstanding
Securities may, by notice to the Trustee, subject to any restrictions in the
Intercreditor Agreement, waive compliance by the Company with any provision of
this Indenture or the Securities without notice to any other Securityholder.
Notwithstanding anything herein to the contrary, without the consent of each
Holder of each outstanding Security affected, an amendment, supplement or
waiver, including a waiver pursuant to Section 5.2, Section 5.3 or Section 5.13,
may not:

    


    (a)
change the Stated Maturity of the principal of, or the payment date of any
installment of interest on, any Security;

    


    (b)
reduce the principal amount of, or any interest or interest rate on, any
Security;

    


    (c)
change the place, manner or currency of payment of principal of, or any interest
on, any Security;

    


    (d)
impair the right to institute suit for the enforcement of any payment on, or
with respect to, or of the conversion of, any Security;

    


    
      (e)
modify
the provisions of Section 2.13 in a manner adverse to
Holders;

    

    


    (f)
except as provided in this Indenture, the Security Agreement and the
Intercreditor Agreement, release all or substantially all of the Collateral
other than in accordance with this Indenture, the Security Agreement and the
Intercreditor Agreement;

    


    (g)
adversely affect the right of Holders to convert Securities in accordance with
ARTICLE IX;

    


    (h)
reduce the percentage of the aggregate principal amount of the outstanding
Securities whose Holders must consent to a modification to or amendment of any
provision of this Indenture or the Securities;

    


    (i)
reduce the percentage of the aggregate principal amount of the outstanding
Securities whose Holders must consent to a waiver of compliance with any
provision of this Indenture or the Securities or a waiver of any Default or
Event of Default; or

    


    (j)
modify the provisions of this Indenture with respect to modification and waiver
(including waiver of a Default or an Event of Default), except to increase the
percentage required for modification or waiver or to provide for the consent of
each affected Holder.

    


    Promptly
after an amendment, supplement or waiver under Section 8.1 or this Section 8.2
becomes effective, the Company shall mail, or cause to be mailed, to
Securityholders a notice briefly describing such amendment, supplement or
waiver. Any failure of the Company to mail such notice shall not in any way
impair or affect the validity of such amendment, supplement or
waiver.

    


    It shall
not be necessary for the consent of the Holders of Securities under this Section
8.2 to approve the particular form of any proposed supplemental indenture or
waiver, but it shall be sufficient if such consent approves the substance
thereof. After a waiver under this section becomes effective, the Company shall
mail to the Holders of Securities affected thereby, a notice briefly describing
the supplemental indenture or waiver. Any failure by the Company to mail or
publish such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture or
waiver.

    Section 8.3 Compliance
with Trust Indenture Act.

    


    Every
amendment to this Indenture or the Securities shall be set forth in a
supplemental indenture hereto that complies with the TIA as then in
effect.

    


    Section 8.4 Revocation
and Effect of Consents.

    


    Until an
amendment, supplement or waiver becomes effective, a consent to it by a Holder
is a continuing consent by the Holder and every subsequent Holder of a Security
or portion of a Security that evidences the same debt as the consenting Holder’s
Security, even if notation of the consent is not made on any Security. However,
any such Holder or subsequent Holder may revoke the consent as to its Security
or portion of a Security if the Trustee receives the notice of revocation before
the date the amendment, supplement or waiver becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

    


    After an
amendment, supplement or waiver becomes effective with respect to the
Securities, it shall bind every Holder unless such amendment, supplement or
waiver makes a change that requires, pursuant to Section 8.2, the consent of
each Holder affected. In that case, the amendment, supplement or waiver shall
bind each Holder of a Security who has consented to it and, provided that notice
of such amendment, supplement or waiver is reflected on a Security that
evidences the same debt as the consenting Holder’s Security, every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder’s Security.

    


    Section 8.5 Notation
on or Exchange of Securities.

    


    If an
amendment, supplement or waiver changes the terms of a Security, the Trustee may
require the Holder of the Security to deliver such amendment, supplement or
waiver to the Trustee. The Trustee may place an appropriate notation on the
Security as directed and prepared by the Company about the changed terms and
return it to the Holder. Alternatively, if the Company so determines, the
Company in exchange for the Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.

    


    Section 8.6 Trustee
Protected.

    


    The
Trustee shall sign any amendment, supplemental indenture or waiver authorized
pursuant to this ARTICLE VIII; provided, however, that the
Trustee need not sign any amendment, supplement or waiver authorized pursuant to
this ARTICLE VIII that adversely affects the Trustee’s rights, duties,
liabilities or immunities. The Trustee shall be entitled to receive and
conclusively rely upon an Opinion of Counsel as to legal matters and an
Officers’ Certificate as to factual matters that any supplemental indenture,
amendment or waiver is permitted or authorized pursuant to this Indenture and
that all conditions precedent to the execution of such supplemental indenture
have been fulfilled.

    (a)
Subject to the provisions of ARTICLE IX, the Securities shall be convertible, at
any time, in integral multiples of $1,000 principal amount, into shares of
Common Stock in accordance with this ARTICLE IX.

    


    (b) The
Company shall not issue fractional shares of Common Stock upon conversion. In
the event of fractional shares, the Company shall pay a cash adjustment for
fractional shares based on the close sale price per share of the Common Stock on
the Trading Day immediately preceding the Conversion Date.

    


    (c)
Notwithstanding anything herein to the contrary, the right to convert the
Securities pursuant to this ARTICLE IX shall terminate at the close of business
on the Maturity Date.

    


    (d) The
initial Conversion Rate shall be   shares of
Common Stock per $1,000 principal amount of Securities. The Conversion Rate
shall be subject to adjustment in accordance with Section 9.7 through Section
9.15.


    
      
         


      

      
        26

        
          

        

      

      
         


      

    

    


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

    


    Section 9.2 Limitation
on the Right to Convert.

    


    9.2.1 Provisional Limitation on the Right
to Convert. Until the Release Date: (i) each Security shall only be
convertible by a Holder (or Beneficial Holder) or by the Company pursuant to
Section 9.3 on any day to the extent that, together with all prior conversions
under such Security or, in the case of a Global Security held for the benefit of
a Beneficial Holder, the total amount of such Security that has been converted
for the benefit of such Holder (Beneficial Holder) does not exceed the product
of (A) 10% of the original principal amount of all Securities held by such
Holder (or Beneficial Holder), and (B) the number of whole or partial calendar
weeks since the Issue Date; and (ii) a Holder (or Beneficial Holder) may only
convert such Securities to the extent of such Holders (or Beneficial Holder’s)
pro rata allocation of [___] shares of Common Stock.

    


    9.2.2 Permanent Limitation on the Right to
Convert. At no time may the Company effect the conversion of any
Securities or issue to a Holder (or Beneficial Holder) shares of Common Stock,
or a Holder (or Beneficial Holder) convert all or a portion of the Securities
into shares of Common Stock, if following such issuance or conversion, the
aggregate number of shares of Common Stock held by any Beneficial Holder of such
Securities would exceed, when aggregated with all other shares of Common Stock
then-owned by such Beneficial Holder and all shares of Common Stock that such
Beneficial Holder is then the beneficial owner of (as determined in accordance
with Section 13(d) of the Exchange Act and the rules thereunder), the number of
shares of Common Stock that would result in such Beneficial Holder beneficially
owning (as determined in accordance with Section 13(d) of the Exchange Act and
the rules thereunder) more than 4.999% of all of the Common Stock outstanding
following such conversion.

    


    Section 9.3 Mandatory
Conversion.

    


    The
Company may elect to cause all or a portion of the principal amount of the
Securities to convert into a number of fully paid and nonassessable shares of
Common Stock equal to the quotient of (i) the principal amount of the Securities
divided by (ii) the Conversion Price in effect on the date of such conversion
(the “Mandatory Conversion Date”) by providing thirty (30) days prior written
notice of such Mandatory Conversion Date. Notwithstanding the foregoing, the
Company may not elect to cause all or a portion of the Securities to convert
into Common Stock on a Mandatory Conversion Date if, on the proposed Mandatory
Conversion Date (i) the Daily VWAP is equal to or greater than $  (as
appropriately adjusted for stock splits, stock dividends, reorganizations,
recapitalizations, stock combinations and the like) for each of the twenty (20)
consecutive prior trading days ending on the trading day immediately prior to
such date, (ii) the Common Stock issuable upon the mandatory conversion would,
immediately upon issuance, be Tradable and (iii) we have sufficient authorized
and unissued shares of Common Stock for full conversion of the Securities. Any
such conversion shall be made pro-rata among all Holders of Securities and
subject to the limitations set forth in Section 9.2. On any such Mandatory
Conversion Date, the Company shall also pay the Holders an amount in cash or, at
the Company’s option following the Authorization Date, provided that the Equity
Conditions are met as of the Mandatory Conversion Date, in shares of Common
Stock, valued at 90% of the Daily VWAP on the Trading Day immediately preceding
the Mandatory Conversion Date, in each case equal to the then accrued and unpaid
interest on the outstanding principal balance of the Securities.

    


    Section 9.4 Conversion
Procedure and Payment Upon Conversion.

    


    9.4.1 To convert a Security
(other than a mandatory conversion pursuant to Section 9.3), a Holder must
satisfy the requirements of paragraph 6 of the Securities. If a Security is
tendered for conversion or upon a mandatory conversion pursuant to Section 9.3
in accordance with this ARTICLE IX, then:

    


    (a) the
Company shall deliver, through the Conversion Agent, the following to the Holder
of such Security:

    


    (i) a
certificate for, or to the extent permissible, in book entry form through DTC,
the number of full shares of Common Stock into which the Securities are
converted (the “Conversion Shares”);


    
      
         


      

      
        27

        
          

        

      

      
         


      

    

    


    (ii) any
cash payment for fractional shares (the “Cash Payment”); and

    


    (iii)
cash or, at the Company’s option following the Authorization Date, provided that
the Equity Conditions are met as of the Conversion Date, shares of Common Stock
valued at 90% of the Daily VWAP on the Trading Day immediately preceding the
Conversion Date, in each case in an amount equal to all accrued and unpaid
interest from, and including, the last Record Date through and excluding the
Conversion Date;

    


    (b) the
Company shall deliver such Conversion Shares and such cash interest Payment or
shares of Common Stock in lieu of interest as soon as practicable following the
Conversion Date applicable to such conversion, but in no event more than two (2)
Business Days after the Conversion Date; and

    


    (c) at
and after the close of business on the Conversion Date, the person in whose name
such certificate representing such Conversion Shares is to be registered shall
be treated as a stockholder of record with respect to such Conversion Shares,
and all rights of the Holder of such Security shall terminate, other than the
right to receive the consideration deliverable upon conversion of such Security
as provided herein.

    


    9.4.2 If any Holder surrenders
a Security for conversion after the close of business on the Record Date for the
payment of an installment of interest and prior to the related Interest Payment
Date, then, notwithstanding such conversion, the interest payable with respect
to such Security on such Interest Payment Date shall be paid on such Interest
Payment Date to the Holder of record of such Security at the close of business
on such Record Date.

    


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

    


    9.4.4 Upon surrender of a
Security that is converted in part, the Trustee shall authenticate for the
Holder a new Security equal in principal amount to the unconverted portion of
the Security surrendered.

    


    9.4.5 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 is not a Legal Holiday.

    


    Section 9.5 Taxes on
Conversion.

    


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

    


    Section 9.6 Company
to Provide Stock.

    


    9.6.1 Subject to Section
9.6.2, the Company shall at all times reserve out of its authorized but unissued
Common Stock or Common Stock held in its treasury enough shares of Common Stock
to permit the conversion, in accordance herewith, of all of the Securities into
shares of Common Stock.

    


    All
shares of Common Stock which may be issued upon conversion of the Securities
shall be validly issued, fully paid and non-assessable and shall be free of
preemptive or similar rights and free of any lien or adverse claim.

    


    The
Company shall comply with all securities laws regulating the offer and delivery
of shares of Common Stock upon conversion of Securities and shall list such
shares on each national securities exchange or automated quotation system on
which the Common Stock is listed.


    
      
         


      

      
        28

        
          

        

      

      
         


      

    

    


    9.6.2 Notwithstanding the
foregoing, as of the date hereof, the Company will not have a sufficient number
of shares of Common Stock authorized and available for issuance to enable it to
convert the Securities or pay interest in shares of Common Stock. The Company
shall seek stockholder approval at its next annual meeting of stockholders, or
alternatively, at a special meeting of stockholders, of, and shall, no later
than the date that is 105 days from the Issue Date, (i) increase the number of
shares of the Company’s Common Stock that is authorized from 6,000,000,000 to at
least [___]; and (ii) effect a 1- ___ reverse stock split of its Common Stock
and to reserve for issuance upon conversion of the Securities such additional
shares of Common Stock sufficient to permit the Company to allow conversion of
the Securities and to pay interest in shares of Common Stock.

    


    Section 9.7 Adjustment
of Conversion Rate.

    


    The
Conversion Rate shall be subject to adjustment from time to time as
follows:

    


    (a) In
case the Company shall (1) pay a dividend in shares of Common Stock to all or
substantially all holders of Common Stock, (2) make a distribution in shares of
Common Stock to all holders of Common Stock, (3) subdivide the outstanding
shares of Common Stock into a greater number of shares of Common Stock or (4)
combine the outstanding shares of Common Stock into a smaller number of shares
of Common Stock, the Conversion Rate shall be adjusted by multiplying the
Conversion Rate in effect immediately prior to close of business on the record
date or effective date, as applicable, of such dividend, distribution,
subdivision or combination by the number of shares of Common Stock which a
person who owns only one share of Common Stock immediately before the record
date or effective date, as applicable, of such dividend, distribution,
subdivision or combination and who is entitled to participate in such dividend,
distribution, subdivision or combination would own immediately after giving
effect to such dividend, distribution, subdivision or combination (without
giving effect to any arrangement pursuant to such dividend, distribution,
subdivision or combination not to issue fractional shares of Common Stock). Any
adjustment made pursuant to this Section 9.7(a) shall become effective
immediately after the record date in the case of a dividend or distribution and
shall become effective immediately after the effective date in the case of a
subdivision or combination.

    


    (b) In
case the Company shall issue rights (other than rights pursuant to a stockholder
rights plan) or warrants to all or substantially all holders of Common Stock,
entitling them to subscribe for or purchase shares of Common Stock (or
securities convertible into or exchangeable or exercisable for Common Stock), at
a price per share (or having a conversion, exchange or exercise price per share)
that is less than the current market price (as determined pursuant to Section
9.7(g)) per share of Common Stock on Trading Day immediately preceding the
announcement of the issuance of such rights or warrants, the Conversion Rate
shall be increased by multiplying the Conversion Rate in effect immediately
prior to such record date by a fraction of which (A) the numerator shall be the
sum of (I) the number of shares of Common Stock outstanding at the close of
business on such record date and (II) the aggregate number of shares (the
“Underlying Shares”) of Common Stock underlying all such issued rights or
warrants (whether by exercise, conversion, exchange or otherwise), and (B) the
denominator shall be the sum of (I) number of shares of Common Stock outstanding
at the close of business on such record date and (II) the number of shares of
Common Stock which the aggregate exercise, conversion, exchange or other price
at which the Underlying Shares may be subscribed for or purchased pursuant to
such rights or warrants would purchase at such current market price per share of
Common Stock. Such increase shall become effective immediately prior to the
opening of business on the day following such record date. In no event shall the
Conversion Rate be decreased pursuant to this Section 9.7(b).


    
      
         


      

      
        29

        
          

        

      

      
         


      

    


    (c) In
case the Company shall dividend or distribute to all or substantially all
holders of Common Stock shares of Capital Stock of the Company or any existing
or future Subsidiary of the Company (other than Common Stock), evidences of
Indebtedness or other assets (other than dividends or distributions requiring an
adjustment to the Conversion Rate in accordance with Section 9.7(d) or Section
9.7(e)), or shall dividend or distribute to all or substantially all holders of
Common Stock rights or warrants to subscribe for or purchase securities (other
than dividends or distributions of rights or warrants requiring an adjustment to
the Conversion Rate in accordance with Section 9.7(b)) (the foregoing
hereinafter in this Section 9.7 called the “Additional Property, then in each
such case the Conversion Rate shall be increased by multiplying the Conversion
Rate in effect immediately prior to the close of business on the record date for
the determination of stockholders entitled to such dividend or distribution by a
fraction of which (A) the numerator shall be the current market price per share
of Common Stock (as determined pursuant to Section 9.7(g)) on such record date
and (B) the denominator shall be an amount equal to (I) such current market
price per share of Common Stock less (II) the fair market value (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution), on such record date, of the portion of the
Additional Property to be dividended or distributed applicable to one share of
Common Stock, such increase to become effective immediately prior to the opening
of business on the day following such record date; provided, however, that if
such denominator is equal to or less than zero, then, in lieu of the foregoing
adjustment to the Conversion Rate, adequate provision shall be made so that each
Holder shall have the right to receive upon conversion of its Securities, in
addition to any consideration otherwise payable as herein provided upon such
conversion, an amount, per $1,000 principal amount of such Securities that a
person owns on such record date, of Additional Property that such Holder would
have received as a result of such dividend or distribution had such Holder
converted the Securities (or a portion thereof) immediately prior to such record
date. Notwithstanding the foregoing, in the event that the Company shall
distribute rights or warrants (other than distributions of rights or warrants
requiring an adjustment to the Conversion Rate in accordance with Section 9.7(b)
and other than rights under the Rights Agreement or stockholders’ rights plan
the Company may have in effect at such time) (collectively, “Rights”) pro rata
to holders of Common Stock, the Company may, in lieu of making any adjustment
pursuant to this Section 9.7(c), make proper provision so that each Holder of a
Security who converts such Security (or any portion thereof) on or after the
record date for such distribution and prior to the expiration or redemption of
the Rights shall be entitled to receive upon such conversion, in addition to any
consideration otherwise payable as herein provided upon such conversion, a
number of Rights, per $1,000 principal amount of such Security, equal to the
number of Rights to which a holder of a number of shares of Common Stock equal
to the Conversion Rate in effect at the close of business on such record date
would be entitled at the time of such conversion in accordance with the terms
and provisions of and applicable to the Rights. Notwithstanding the first
sentence of this Section 9.7(c), a distribution of rights pursuant to a
stockholders’ rights plan shall not constitute a dividend or distribution
requiring an adjustment to the Conversion Rate pursuant to the first sentence of
this Section 9.7(c), provided that (1) such rights have not separated from the
Common Stock at the time of such distribution; and (2) the Company has made
adequate provision in accordance with Section 9.15 for Holders to receive such
rights upon conversion. In no event shall the Conversion Rate be decreased
pursuant to this Section 9.7(c).

    


    (d) In
case the Company shall, by dividend or otherwise, at any time make a
distribution of cash (excluding any cash that is distributed as part of a
distribution requiring a Conversion Rate adjustment pursuant to Section 9.7(e))
to all or substantially all holders of Common Stock, the Conversion Rate shall
be increased by multiplying the Conversion Rate in effect immediately prior to
the Ex Date for such distribution by a fraction (A) whose numerator shall be the
current market price per share of Common Stock (as determined pursuant to
Section 9.7(g)) on the Trading Day immediately preceding the Ex Date and (B)
whose denominator shall be an amount equal to (I) such current market price per
share of Common Stock less (II) the amount of the distribution per share of
Common Stock; provided, however, that the Conversion Rate shall not be adjusted
pursuant to this Section 9.7(d) to the extent, and only to the extent, such
adjustment would cause the Conversion Price to be less than par value; provided
further that, if the denominator of such fraction shall be equal to or less than
zero, the Conversion Rate shall be instead adjusted so that the Conversion Price
is equal to par value. An adjustment to the Conversion Rate pursuant to this
Section 9.7(d) shall become effective immediately after the opening of business
on such Ex Date. In no event shall the Conversion Rate be decreased pursuant to
this Section 9.7(d).

    


    (e) In
case the Company shall distribute cash or other consideration in respect of a
tender offer or exchange offer made by the Company for all or any portion of the
Common Stock where the sum of the aggregate amount of such cash distributed and
the aggregate fair market value (as determined in good faith by the Board of
Directors, whose determination shall be conclusive and set forth in a Board
Resolution), as of the Expiration Date (as defined below), of such other
consideration distributed (such sum, the “Aggregate Amount”) expressed as an
amount per share of Common Stock validly tendered or exchanged, and not
withdrawn, pursuant to such tender offer or exchange offer as of the Expiration
Time (as defined below) (such tendered or exchanged shares of Common Stock, the
“Purchased Shares”) exceeds the Daily VWAP on the first Trading Day after last
date (such last date, the “Expiration Date”) on which tenders or exchanges could
have been made pursuant to such tender offer or exchange offer (as the same may
be amended through the Expiration Date), then the Conversion Rate shall be
increased by multiplying the Conversion Rate in effect immediately prior to the
close of business on the Expiration Date by a fraction (A) whose numerator is
equal to the sum of (I) the Aggregate Amount and (II) the product of (a) the
Daily VWAP on the first Trading Day after the Expiration Date and (b) an amount
equal to (i) the number of shares of Common Stock outstanding as of the last
time (the “Expiration Time”) at which tenders or exchanges could have been made
pursuant to such tender offer or exchange offer (including all Purchased Shares)
less (ii) the Purchased Shares and (B) whose denominator is equal to the product
of (I) the number of shares of Common Stock outstanding as of the Expiration
Time (including all Purchased Shares) and (II) such Daily VWAP.

    An
increase, if any, to the Conversion Rate pursuant to this Section 9.7(e) shall
become effective immediately prior to the opening of business on the second
(2nd) Business Day following the Expiration Date. In the event that the Company
is obligated to purchase shares of Common Stock pursuant to any such tender
offer or exchange offer, but the Company is permanently prevented by applicable
law from effecting any such purchases, or all such purchases are rescinded, then
the Conversion Rate shall again be adjusted to be the Conversion Rate which
would then be in effect if such tender offer or exchange offer had not been
made. If the application of this Section 9.7(e) to any tender offer or exchange
offer would result in a decrease in the Conversion Rate, no adjustment shall be
made for such tender offer or exchange offer under this Section
9.7(e).

    


    (f)
Reserved

    


    (g) For
the purpose of any computation under subsections (a), (b), (c) or (d) above of
this Section 9.7, the current market price per share of Common Stock on any date
shall be deemed to be the average of the Daily VWAP for the ten (10) consecutive
Trading Days ending on, but excluding, the earlier of such date and the Ex Date
with respect to the issuance or distribution requiring such computation;
provided, however, that such current market price per share of Common Stock
shall be appropriately adjusted by the Company, in its good faith determination,
to account for any adjustment, pursuant hereto, to the Conversion Rate that
shall become effective, or any event requiring, pursuant hereto, an adjustment
to the Conversion Rate where the Ex Date of such event occurs, at any time
during the period that begins on, and includes, the first day of such ten (10)
consecutive Trading Days and ends on, and includes, the date when the adjustment
to the Conversion Rate on account of the event requiring the computation of such
current market price becomes effective.

    


    The term
“Ex Date,” (i) when used with respect to any issuance or distribution, means the
first date on which the Common Stock trades the regular way on the relevant
exchange or in the relevant market from which the Daily VWAP was obtained
without the right to receive such issuance or distribution, (ii) when used with
respect to any subdivision or combination of shares of Common Stock, means the
first date on which the Common Stock trades the regular way on such exchange or
in such market after the time at which such subdivision or combination becomes
effective, and (iii) when used with respect to any tender offer or exchange
offer means the first date on which the Common Stock trades the regular way on
such exchange or in such market after the expiration time of such tender offer
or exchange offer (as it may be amended or extended).

    


    Section 9.8 No
Adjustment.

    


    If any
rights, options or warrants issued by the Company and requiring an adjustment to
the Conversion Rate in accordance with Section 9.7 are only exercisable upon the
occurrence of certain triggering events, then the Conversion Rate will not be
adjusted as provided in Section 9.7 until the earliest of such triggering event
occurs. Upon the expiration or termination of any such rights, options or
warrants without the exercise of such rights, options or warrants, the
Conversion Rate then in effect shall be adjusted immediately to the Conversion
Rate which would have been in effect at the time of such expiration or
termination had such rights, options or warrants, to the extent outstanding
immediately prior to such expiration or termination, never been issued. However,
if prior to the occurrence of such a triggering event, the Holder of a Security
converts into Common Stock, in addition to the issuance of the Common Stock,
upon conversion the Company will also issue such Holder the rights, options or
warrants subject to such triggering events that such Holder would have received
if the Holder had converted into Common Stock prior to the issuance of such
rights, options or warrants.

    


    If any
dividend or distribution is declared and the Conversion Rate is adjusted
pursuant to Section 9.7 on account of such dividend or distribution, but such
dividend or distribution is thereafter not paid or made, the Conversion Rate
shall again be adjusted to the Conversion Rate which would then be in effect had
such dividend or distribution not been declared.

    


    No
adjustment to the Conversion Rate need be made pursuant to Section 9.7 for a
transaction if Holders are to participate in the transaction without conversion
on a basis and with notice that the Board of Directors determines in good faith
to be fair and appropriate in light of the basis and notice on which holders of
Common Stock participate in the transaction (which determination shall be
described in a Board Resolution).

    Section 9.9 Other
Adjustments.

    


    In the
event that, as a result of an adjustment made pursuant to this ARTICLE IX, the
Holder of any Security thereafter surrendered for conversion shall become
entitled to receive any shares of Capital Stock other than shares of Common
Stock, thereafter the Conversion Rate of such other shares so receivable upon
conversion of any Security shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this ARTICLE IX.

    


    Section 9.10 Adjustments
for Tax Purposes.

    


    Except as
prohibited by law or by the rules of the OTC Bulletin Board or any other stock
exchange on which the Company’s Common Stock is then traded, the Company may
make such increases in the Conversion Rate, in addition to those required by
Section 9.7 hereof, as it determines to be advisable in order that any stock
dividend, subdivision of shares, distribution of rights to purchase stock or
securities or distribution of securities convertible into or exchangeable for
stock made by the Company or to its stockholders will not be taxable to the
recipients thereof.

    


    Section 9.11 Notice of
Adjustment.

    


    Whenever
the Conversion Rate is adjusted, the Company shall promptly mail to Holders at
the addresses appearing on the Registrar’s books a notice of the adjustment and
file with the Trustee an Officers’ Certificate briefly stating the facts
requiring the adjustment and the manner of computing it. The certificate shall
be conclusive evidence of the correctness of such adjustment.

    


    Section 9.12 Notice of
Certain Transactions.

    


    In the
event that:

    


    (a) the
Company takes any action, or becomes aware of any event, which would require an
adjustment in the Conversion Rate,

    


    (b) the
Company takes any action that would require a supplemental indenture pursuant to
Section 9.13, or

    


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

    


    the
Company shall mail to Holders at the addresses appearing on the Registrar’s
books and the Trustee a written notice stating the proposed record, effective or
expiration date, as the case may be, of any transaction referred to in clause
(a), (b) or (c) of this Section 9.12. The Company shall mail such notice at
least twenty (20) days before such date; however, failure to mail such notice or
any defect therein shall not affect the validity of any transaction referred to
in clause (a), (b) or (c) of this Section 9.12.

    Section 9.13 Effect of
Reclassifications, Consolidations, Mergers, Binding Share
Exchanges or Sale on Conversion Privilege.

    


    If any of
the following shall occur, namely: (i) any reclassification or change in the
Common Stock issuable upon conversion of Securities (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 of Common Stock), (ii) any
consolidation, merger or binding share exchange to which the Company is a party
other than a merger in which the Company is the continuing Person and which does
not result in any reclassification of, or change (other than a change in name,
or 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) in, the Common Stock or
(iii) any sale, transfer, lease, conveyance or other disposition of all or
substantially all of the Company’s property or assets, in each case pursuant to
which the Common Stock would be converted into or exchanged for, or would
constitute solely the right to receive, cash, securities or other property, then
the Company or such successor or purchasing Person, as the case may be, shall,
as a condition precedent to such reclassification, change, consolidation,
merger, binding share exchange, sale, transfer, lease, conveyance or
disposition, execute and deliver to the Trustee a supplemental indenture in form
reasonably satisfactory to the Trustee providing that, at and after the
effective time of such reclassification, change, consolidation, merger, binding
share exchange, sale, transfer, lease, conveyance or disposition, the Holder of
each Security then outstanding shall have the right to convert such Security (if
otherwise convertible pursuant to this ARTICLE IX) into the kind and amount of
cash, securities or other property (collectively, “Reference Property”)
receivable upon such reclassification, change, consolidation, merger, binding
share exchange, sale, transfer, lease, conveyance or disposition which a Holder
of such Security would have received if the Holder had converted the Security
immediately before the transaction (assuming, if holders of Common Stock shall
have the opportunity to elect the form of consideration to receive pursuant to
such reclassification, change, consolidation, merger, binding share exchange,
sale, transfer, lease, conveyance or disposition, that the Collective Election
shall have been made with respect to such election). If holders of Common Stock
shall have the opportunity to elect the form of consideration to receive
pursuant to such reclassification, change, consolidation, merger, binding share
exchange, sale, transfer, lease, conveyance or disposition, then the Company
shall make adequate provision to give Holders, treated as a single class, a
reasonable opportunity to elect (the “Collective Election”) the form of such
consideration for purposes of determining the composition of the Reference
Property referred to in the immediately preceding sentence, and once such
election is made, such election shall apply to all Holders after the effective
time of such reclassification, change, consolidation, merger, binding share
exchange, sale, transfer, lease, conveyance or disposition. The supplemental
indenture referred to in the first sentence of this paragraph shall provide for
adjustments of the Conversion Rate which shall be as nearly equivalent as may be
practicable to the adjustments of the Conversion Rate provided for in this
ARTICLE IX. The foregoing, however, shall not in any way affect the right a
Holder of a Security may otherwise have, pursuant to Section 9.7(c) or Section
9.15, to receive rights or warrants upon conversion of a Security. If, in the
case of any such consolidation, merger, binding share exchange, sale, transfer,
lease, conveyance or disposition, the stock or other securities and property
(including cash) receivable thereupon by a holder of Common Stock includes
shares of stock or other securities and property of a Person other than the
successor or purchasing Person, as the case may be, in such consolidation,
merger, binding share exchange, sale, transfer, lease, conveyance or
disposition, then such supplemental indenture shall also be executed by such
other Person and shall contain such additional provisions to protect the
interests of the Holders of the Securities as the Board of Directors in good
faith shall reasonably determine necessary by reason of the foregoing (which
determination shall be described in a Board Resolution). The provisions of this
Section 9.13 shall similarly apply to successive consolidations, mergers,
binding share exchanges, sales, transfers, leases, conveyances or
dispositions.

    


    In the
event the Company shall execute a supplemental indenture pursuant to this
Section 9.13, the Company shall promptly file with the Trustee an Officers’
Certificate briefly stating the reasons therefor, the kind or amount of shares
of stock or securities or property (including cash) receivable by Holders of the
Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, binding share exchange, sale,
transfer, lease, conveyance or disposition and any adjustment to be made with
respect thereto.

    


    The
Company shall not become a party to any such reclassification, change,
consolidation, merger, binding share exchange, sale, transfer, lease, conveyance
or disposition unless the terms thereof are consistent with this Section
9.13.

    


    Section 9.14 Trustee’s
Disclaimer.

    


    The
Trustee has no duty to determine when an adjustment under this ARTICLE IX should
be made, how it should be made or what such adjustment should be, but may accept
as conclusive evidence of the correctness of any such adjustment, and shall be
protected in relying upon, the Officers’ Certificate with respect thereto which
the Company is obligated to file with the Trustee pursuant to Section 9.11
hereof. The Trustee makes no representation as to the validity or value of any
securities or assets issued upon conversion of Securities, and the Trustee shall
not be responsible for the failure by the Company to comply with any provisions
of this ARTICLE IX.

    


    The
Trustee shall not be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture executed pursuant to
Section 9.13, but may accept as conclusive evidence of the correctness thereof,
and shall be protected in relying upon, the Officers’ Certificate with respect
thereto which the Company is obligated to file with the Trustee pursuant to
Section 9.13 hereof.

    Section 9.15 Rights
Distributions Pursuant to the Stockholder Rights Plan.

    


    Upon
conversion of any Security or a portion thereof, the Company shall make
provision for the Holder thereof, to the extent such Holder is to receive shares
of Common Stock upon such conversion, to receive, in addition to, and
concurrently with the delivery of, the consideration otherwise payable hereunder
upon such conversion, the rights described in the Rights Agreement or any other
stockholders’ rights plan the Company may have in effect at such time, unless
such rights have separated from the Common Stock at the time of such conversion,
in which case the Conversion Rate shall be adjusted upon such separation in
accordance with Section 9.7(c).

    


    ARTICLE
X.

    SUBORDINATION

    


    Section 10.1 Agreement
of Subordination.

    


    The
Company covenants and agrees, and each holder of Securities issued hereunder by
its acceptance thereof likewise covenants and agrees, that all Securities shall
be issued subject to the provisions of this Article X, and each Holder, whether
upon original issue or upon registration of transfer, assignment or exchange
thereof, accepts and agrees to be bound by such provisions.

    


    The
payment of the principal of and interest on all Securities issued hereunder
shall, to the extent and in the manner hereinafter set forth, be subordinated
and subject in right of payment to the prior payment in full of all Senior Debt,
whether outstanding at the date of this Indenture or thereafter
incurred.

    


    No
provision of this Article X shall prevent the occurrence of any default or Event
of Default hereunder.

    


    Section 10.2 Payments
to Holders.

    


    No
payment shall be made with respect to the principal of or interest on the
Securities, except payments and distributions made by the Trustee as permitted
by the first or second paragraph of Section 10.5, if:

    


    (A) a
default in the payment of principal, interest, rent or other obligations in
respect of Senior Debt occurs and is continuing beyond any applicable period of
grace (a “Payment Default”), unless and until such Payment Default shall have
been cured or waived or shall have ceased to exist; or

    


    (B) a
default, other than a Payment Default, on any Senior Debt occurs and is
continuing that then permits holders of such Senior Debt or a Representative
thereof to accelerate its maturity (or in the case of any lease, a default
occurs and is continuing that permits the lessor to either terminate the lease
or require the Company to make an irrevocable offer to terminate the lease
following an event of default thereunder) (a “Non-Payment Default”), unless and
until such Non-Payment Default shall have been cured or waived or shall have
ceased to exist.

    


    The
Company may and shall resume payments on and distributions in respect of the
Securities upon the date upon which any such Payment Default or Non-Payment is
cured or waived or ceases to exist.

    


    Upon any
payment by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding up or liquidation or reorganization of the Company,
whether voluntary or involuntary or in bankruptcy, insolvency, receivership or
other proceedings, all amounts due or to become due upon all Senior Debt shall
first be paid in full in cash or other payment satisfactory to the holders of
such Senior Debt or provision is made for such payment thereof in accordance
with its terms provided for in cash or other payment satisfactory to the holders
of such Senior Debt before any payment is made on account of the principal of or
interest on the Securities (except payments made pursuant to Article VII from
monies deposited with the Trustee pursuant thereto prior to commencement of
proceedings for such dissolution, winding up, liquidation or reorganization),
and upon any such dissolution or winding up or liquidation or reorganization of
the Company or bankruptcy, insolvency, receivership or other similar proceeding,
any payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the holders of
the Securities or the Trustee would be entitled, except for the provisions of
this Article X, shall (except as aforesaid) be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the Securities or by
the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Debt (pro rata to such holders on the basis of the respective
amounts of Senior Debt held by such holders, or as otherwise required by law or
a court order) or their Representative or Representatives, as their respective
interests may appear, to the extent necessary to pay all Senior Debt in full, in
cash or other payment satisfactory to the holders of such Senior Debt, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Debt, before any payment or distribution is made to the holders of the
Securities or to the Trustee.

    For
purposes of this Article X, the words, “cash, property or securities” shall not
be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article X with respect to
the Securities to the payment of all Senior Debt which may at the time be
outstanding provided that (i) the Senior Debt is assumed by the new corporation,
if any, resulting from any reorganization or readjustment, and (ii) the rights
of the holders of Senior Debt (other than leases which are not assumed by the
Company or the new corporation, as the case may be) are not, without the consent
of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another
corporation or the liquidation or dissolution of the Company following the
conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another Person upon the terms and conditions provided for in
Section 9.13 shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 10.2 if such other Person shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions stated in Section 9.13.

    


    In the
event of the acceleration of the Securities because of an Event of Default, no
payment or distribution shall be made to the Trustee or any holder of Securities
in respect of the principal of or interest on the Securities except payments and
distributions made by the Trustee as permitted by the first or second paragraph
of Section 10.5, until all Senior Debt has been paid in full in cash or other
payment satisfactory to the holders of Senior Debt If payment of the Securities
is accelerated because of an Event of Default, the Company or the Trustee shall
promptly notify holders of Senior Debt of the acceleration.

    


    In the
event that, notwithstanding the foregoing provisions, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing provisions in this Section 10.2, shall
be received by the Trustee or the holders of the Securities before all Senior
Debt is paid in full in cash or other payment satisfactory to the holders of
such Senior Debt, or provision is made for such payment thereof in accordance
with its terms in cash or other payment satisfactory to the holders of such
Senior Debt, such payment or distribution shall be held in trust for the benefit
of and shall be paid over or delivered to the holders of Senior Debt or their
Representative or Representatives, as their respective interests may appear, as
calculated by the Company, for application to the payment of any Senior Debt
remaining unpaid to the extent necessary to pay all Senior Debt in full in cash
or other payment satisfactory to the holders of such Senior Debt, after giving
effect to any concurrent payment or distribution to or for the holders of such
Senior Debt.

    


    Nothing
in this Section 10.2 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 6.7. This Section 10.2 shall be subject to the further
provisions of Section 10.5.

    


    Section 10.3 Subrogation
of Securities.

    


    Subject
to the payment in full of all Senior Debt, the rights of the holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Debt pursuant to the provisions of this
Article X (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to other indebtedness of the
Company to substantially the same extent as the Securities are subordinated and
is entitled to like rights of subrogation) to the rights of the holders of
Senior Debt to receive payments or distributions of cash, property or securities
of the Company applicable to the Senior Debt until the principal and interest on
the Securities shall be paid in full, and, for the purposes of such subrogation,
no payments or distributions to the holders of the Senior Debt of any cash,
property or securities to which the holders of the Securities or the Trustee
would be entitled except for the provisions of this Article X, and no payment
over pursuant to the provisions of this Article X, to or for the benefit of the
holders of Senior Debt by holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Debt, and the
holders of the Securities, be deemed to be a payment by the Company to or on
account of the Senior Debt, and no payments or distributions of cash, property
or securities to or for the benefit of the holders of the Securities pursuant to
the subrogation provisions of this Article X, which would otherwise have been
paid to the holders of Senior Debt, shall be deemed to be a payment by the
Company to or for the account of the Securities. It is understood that the
provisions of this Article X are and are intended solely for the purposes of
defining the relative rights of the holders of the Securities, on the one hand,
and the holders of the Senior Debt, on the other hand.

    Nothing
contained in this Article X or elsewhere in this Indenture or in the Securities
is intended to or shall impair, as among the Company, its creditors other than
the holders of Senior Debt, and the holders of the Securities, the obligation of
the Company, which is absolute and unconditional, to pay to the holders of the
Securities the principal of and interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the holders of the Securities and
creditors of the Company other than the holders of the Senior Debt, nor shall
anything herein or therein prevent the Trustee or the holder of any Securities
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article X of the
holders of Senior Debt in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.

    


    Upon any
payment or distribution of assets of the Company referred to in this Article X,
the Trustee, subject to the provisions of Section 6.1, and the holders of the
Securities shall be entitled to rely upon any order or decree made by any court
of competent jurisdiction in which such bankruptcy, dissolution, winding up,
liquidation or reorganization proceedings are pending, or a certificate of the
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, delivered to the Trustee or to the holders
of the Securities, for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon and all other
facts pertinent thereto or to this Article X.

    


    Section 10.4 Authorization
to Effect Subordination.

    


    Each
holder of a Security by the holder’s acceptance thereof authorizes and directs
the Trustee on the holder’s behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article X and
appoints the Trustee to act as the holder’s attorney-in-fact for any and all
such purposes. Subject to the Intercreditor Agreement, if the Trustee does not
file a proper proof of claim or proof of debt in the form required in any
proceeding referred to in Section 5.4 hereof at least thirty (30) days before
the expiration of the time to file such claim, the holders of any Senior Debt or
their Representatives are hereby authorized to file an appropriate claim for and
on behalf of the holders of the Securities.

    


    Section 10.5 Notice to
Trustee.

    


    The
Company shall give prompt written notice in the form of an Officers’ Certificate
to a Responsible Officer of the Trustee and to any paying agent of any fact
known to the Company that would prohibit the making of any payment of monies to
or by the Trustee or any paying agent in respect of the Securities pursuant to
the provisions of this Article X. Notwithstanding the provisions of this Article
X or any other provision of this Indenture, the Trustee shall not be charged
with knowledge of the existence of any facts that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article X, unless and until a Responsible Officer of
the Trustee shall have received written notice thereof at the Corporate Trust
Office from the Company (in the form of an Officers’ Certificate) or a
Representative or a holder or holders of Senior Debt, and before the receipt of
any such written notice, the Trustee, subject to the provisions of Section 6.1,
shall be entitled in all respects to assume that no such facts exist; provided,
however, that if on a date not less than one Business Day prior to the date upon
which by the terms hereof any such monies may become payable for any purpose
(including, without limitation, the payment of the principal of or interest on
any Security) the Trustee shall not have received, with respect to such monies,
the notice provided for in this Section 10.5, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
apply monies received to the purpose for which they were received, and shall not
be affected by any notice to the contrary that may be received by it on or after
such prior date.

    Notwithstanding
anything in this Article X to the contrary, nothing shall prevent any payment by
the Trustee to the Holders of monies deposited with it pursuant to Section 7.1,
if a Responsible Officer of the Trustee shall not have received written notice
at the Corporate Trust Office on or before one Business Day prior to the date
such payment is due that such payment is not permitted under Section 10.1 or
10.2.

    


    The
Trustee, subject to the provisions of Section 6.1, shall be entitled to rely on
the delivery to it of a written notice by a Representative or a person
representing himself to be a holder of Senior Debt (or a trustee on behalf of
such holder) to establish that such notice has been given by a Representative or
a holder of Senior Debt or a trustee on behalf of any such holder or holders.
The Trustee shall not be required to make any payment or distribution to or on
behalf of a holder of Senior Debt pursuant to this Article X unless it has
received satisfactory evidence as to the amount of Senior Debt held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article X.

    


    Section 10.6 Trustee’s
Relation to Senior Debt.

    


    The
Trustee, in its individual capacity, shall be entitled to all the rights set
forth in this Article X in respect of any Senior Debt at any time held by it, to
the same extent as any other holder of Senior Debt, and nothing in Section 6.11
or elsewhere in this Indenture shall deprive the Trustee of any of its rights as
such holder.

    


    With
respect to the holders of Senior Debt, the Trustee undertakes to perform or to
observe only such of its covenants and obligations as are specifically set forth
in this Article X, and no implied covenants or obligations with respect to the
holders of Senior Debt shall be read into this Indenture against the Trustee.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Debt and, subject to the provisions of Section 6.1, the Trustee shall not
be liable to any holder of Senior Debt (i) for any failure to make any payments
or distributions to such holder or (ii) if it shall pay over or deliver to
holders of Securities, the Company or any other Person money in compliance with
this Article X.

    


    Section 10.7 No
Impairment of Subordination.

    


    No right
of any present or future holder of any Senior Debt to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.
Senior Debt may be created, renewed or extended and holders of Senior Debt may
exercise any rights under any instrument creating or evidencing such Senior
Debt, including, without limitation, any waiver of default thereunder, without
any notice to or consent from the holders of the Securities or the Trustee. No
compromise, alteration, amendment, modification, extension, renewal or other
change of, or waiver, consent or other action in respect of, any liability or
obligation under or in respect of the Senior Debt or any terms or conditions of
any instrument creating or evidencing such Senior Debt shall in any way alter or
affect any of the provisions of this Article X or the subordination of the
Securities provided thereby.

    


    Section 10.8 Certain
Conversions Not Deemed Payment.

    


    For the
purposes of this Article X only, (1) the issuance and delivery of junior
securities upon conversion of Securities in accordance with Article IX shall not
be deemed to constitute a payment or distribution on account of the principal of
or interest on Securities or on account of the purchase or other acquisition of
Securities, (2) the issuance and delivery of Common Stock as payment of interest
in accordance with Section 2.7 shall not be deemed to constitute a payment or
distribution on account of the principal of or interest on Securities or on
account of the purchase or other acquisition of Securities and (3) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 9.4), property or securities (other than junior securities)
upon conversion of a Security shall be deemed to constitute payment on account
of the principal of or interest on such Security. For the purposes of this
Section 10.8, the term “junior securities” means (a) shares of any stock of any
class of the Company or (b) securities of the Company that are subordinated in
right of payment to all Senior Debt that may be outstanding at the time of
issuance or delivery of such securities to substantially the same extent as, or
to a greater extent than, the Securities are so subordinated as provided in this
Article X. Nothing contained in this Article X or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Company, its
creditors (other than holders of Senior Debt) and the Holders, the right, which
is absolute and unconditional, of the Holder of any Security to convert such
Security in accordance with Article IX.

    Section 10.9 Article
Applicable to Paying Agents.

    


    If at any
time any paying agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article
X shall (unless the context otherwise requires) be construed as extending to and
including such paying agent within its meaning as fully for all intents and
purposes as if such paying agent were named in this Article X in addition to or
in place of the Trustee; provided, however, that the
first paragraph of Section 10.5 shall not apply to the Company or any Affiliate
of the Company if it or such Affiliate acts as paying agent.

    


    The
Trustee shall not be responsible for the actions or inactions of any other
paying agents (including the Company if acting as its own paying agent) and
shall have no control of any funds held by such other paying
agents.

    


    Section 10.10 Senior
Debt Entitled to Rely.

    


    The
holders of Senior Debt shall have the right to rely upon this Article X, and no
amendment or modification of the provisions contained herein shall diminish the
rights of such holders unless such holders shall have agreed in writing
thereto.

    


    Section 10.11 Reliance
on Judicial Order or Certificate of Liquidating Agent.

    


    Upon any
payment or distribution of assets of the Company referred to in this Article X,
the Trustee and the Holders shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Debt and other indebtedness of the Company, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article X.

    


    Section 10.12 Intercreditor
Agreement and Security Documents.

    


    10.12.1 The due and punctual
payment of the principal of, and interest on, the Securities when due and as the
same shall be due and payable, whether on an Interest Payment Date, at Stated
Maturity, by acceleration, conversion or otherwise, interest on the overdue
principal of and interest (to the extent permitted by law), if any, on the
Securities and performance of all other obligations under this Indenture, the
Securities, and the Security Documents shall be secured as provided in the
Security Documents and shall be subject to the Intercreditor Agreement. The
security interests in the Collateral created by the Security Documents as now or
hereafter in effect shall be held by the Trustee for the equal and ratable
benefit and security of the Holders of the Securities without preference,
priority or distinction of any thereof over any other by reason, or difference
in time, of issuance, sale or otherwise, and for the enforcement of the payment
of principal of, and interest on, the Securities in accordance with their
terms.

    


    10.12.2 Each Holder, by its
acceptance of the Securities, consents and agrees to the terms of the Security
Documents and the Intercreditor Agreement (including without limitations the
provisions providing for the foreclosure and release of Collateral) as the same
may be in effect from time to time in accordance with their terms and authorizes
and directs the Trustee to enter into the Security Documents and the
Intercreditor Agreement and to perform its obligations and exercise its rights
thereunder in accordance therewith. The Company initially appoints the Trustee
as collateral agent under the Security Documents and the Intercreditor
Agreement. Any successor Trustee will act as collateral agent and/or Trustee
under the Security Documents and the Intercreditor Agreement or appoint another
Person to act in such capacity.

    


    10.12.3 Collateral shall be
released from the liens created by the Security Documents from time to time at
the sole cost and expense of the Company:

    


    (a) upon
payment in full of the Securities and discharge of the indenture in accordance
with Article VII;


    
      
         


      

      
        38

        
          

        

      

      
         


      

    

    


    (b) upon
any sale, transfer or other disposition by the Company of such Collateral
(provided that only the Collateral subject to such sale, transfer or other
disposition shall be released); and

    


    (c) as
required pursuant to the terms of the Intercreditor Agreement;

    


    provided
that the Trustee shall not release any such liens unless and until it shall have
received an Officer’s Certificate and if requested by the Trustee, an Opinion of
Counsel, stating that all conditions precedent hereunder have been met. Upon
compliance with the foregoing, the Trustee shall execute, deliver or acknowledge
any necessary or proper instruments of termination, satisfaction or release to
evidence the release of Collateral in accordance with the provisions hereof, the
Security Documents and the Intercreditor Agreement.

    


    10.12.4 Subject to the terms
of the Intercreditor Agreement, the Trustee may, in its sole discretion and
without the consent of the Holders, on behalf of the Holders, take all actions
it deems necessary or appropriate in order to (a) enforce any of the terms of
the Security Documents, and (b) collect and receive any and all amounts payable
in respect of the obligations of the Company hereunder and under the Securities
and the Security Documents. Subject to the terms of the Intercreditor Agreement,
the Trustee shall have the power to institute and maintain such suits and
proceedings as it may deem expedient to prevent any impairment of the Collateral
by any acts that may be unlawful or in violation of the Indenture or the
Security Documents, and such suits and proceedings as the Trustee may deem
expedient to preserve or protect its interest and the interests of the Holders
in the Collateral and the proceeds arising therefrom, including power to
institute and maintain suits or proceedings to restrain the enforcement of or
compliance with any legislative or other governmental enactment, rule, or order
that may be unconstitutional or otherwise invalid, if the enforcement of, or
compliance with, such enactment, rule or order would impair the security granted
under the Security Documents or be prejudicial to the interests of the Holders
or the Trustee.

    


    10.12.5 Subject to the
Intercreditor Agreement, the Trustee is authorized to receive any funds for the
benefit of the Holders distributed pursuant to the Security Documents and to
make further distributions of such funds to the Holders according to the
provisions of this Indenture and the Security Documents.

Company will pay, in money of the United States that at the time of payment is
legal tender for payment of public and private debts, all amounts due in cash
with respect to the Securities, which amounts shall be paid (A) in the case this
Security is in global form, by wire transfer of immediately available funds to
the account designated by the Depository for the Securities or its nominee; (B)
in the case of a Security that is held, other than global form, by a Holder of
Securities, by wire transfer of immediately available funds to the account
specified by such Holder or, if such Holder does not specify an account, by
mailing a check to the address of such Holder set forth in the register of the
Registrar; and (C) in the case of a Security that is held, other than global
form, by a Holder of Securities, by mailing a check to the address of such
Holder set forth in the register of the Registrar.

    


    4. Paying Agent, Registrar, Conversion
Agent. Initially, U.S. Bank National Association (the “Trustee”) will act as Paying
Agent, Registrar and Conversion Agent. The Company may change any Paying Agent,
Registrar or Conversion Agent without notice.

    


    5. Indenture. The Company issued
the Securities under an indenture dated as of [___] (the “Indenture”) between the
Company and the Trustee. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”) as amended and in effect
from time to time. The Securities are subject to all such terms, and Holders are
referred to the Indenture and the TIA for a statement of such terms. The
Securities are junior obligations of the Company limited to $[___] aggregate
principal amount secured by all of the Company’s assets, will be subordinated to
the Company’s senior secured indebtedness and will be effectively senior to the
Company’s existing and future unsecured indebtedness. Terms used herein without
definition and which are defined in the Indenture have the meanings assigned to
them in the Indenture.

    6. Conversion. The Securities
shall be convertible, at any time, in integral multiples of $1,000 principal
amount, into cash, shares of Common Stock or a combination of cash and shares of
Common Stock in accordance with ARTICLE IX of the Indenture.

    


    Notwithstanding
anything herein to the contrary, the right to convert the Securities pursuant to
ARTICLE IX of the Indenture shall terminate at the close of business on the
Maturity Date.

    


    To
convert a Security (other than a mandatory conversion pursuant to Section 9.3 of
the Indenture), a Holder must (1) complete and sign the Conversion Notice, with
appropriate signature guarantee, on the back of the Security, (2) surrender the
Security to a Conversion Agent, (3) furnish appropriate endorsements and
transfer documents if required by the Registrar or Conversion Agent, and (4) pay
any tax or duty if required pursuant to the Indenture. A Holder may convert a
portion of a Security if the portion is $1,000 principal amount or an integral
multiple of $1,000 principal amount. In the case of a Security issued as a
Global Security, the Beneficial Holder of such Security must also send a copy of
the Conversion Notice, with appropriate signature guarantee, on the back of the
Security, to the Company, and must comply with the Depository’s then applicable
conversion program procedures.

    


    If a
Security is tendered for conversion in accordance with the Indenture, then the
Holder of such Security shall be entitled to receive shares of Common Stock and
cash, if applicable, in accordance with Section 9.4.1 of the
Indenture.

    


    The
initial Conversion Rate is [___] shares of Common Stock per $1,000 principal
amount of Securities subject to adjustment in the event of certain circumstances
as specified in the Indenture. The Company will deliver a check in lieu of any
fractional share. On conversion, the Company shall pay to Holder all unpaid and
accrued interest on the Securities. If any Holder surrenders a Security for
conversion after the close of business on the record date for the payment of an
installment of interest and prior to the related interest payment date, then,
notwithstanding such conversion, the interest payable with respect to such
Security on such interest payment date shall be paid on such interest payment
date to the Holder of record of such Security at the close of business on such
record date.

    


    7. Mandatory Conversion. On any
Mandatory Conversion Date, subject to the limitations on conversion set forth in
Section 8, the Company may cause all of the principal amount of the Securities
to convert into a number of fully paid and nonassessable shares of Common Stock
equal to the quotient of (i) the principal amount of the Securities divided by
(ii) the Conversion Price in effect on the Mandatory Conversion Date by
providing thirty (30) days prior written notice of such Mandatory Conversion
Date. Notwithstanding the foregoing, the Company may not elect to cause all or a
portion of the Securities to convert into Common Stock, unless at such time the
Company shall have met the conditions set forth in Section 9.3 of the Indenture.
On any such Mandatory Conversion Date, the Company shall also pay the Holders
cash or, at the Company’s option following the Authorization Date, provided the
Equity Conditions are met, shares of Common Stock valued at 90% of the Daily
VWAP on the Trading Day immediately preceding the Mandatory Conversion
Date.

    


    11.15.1 8. Limitation on the Right to
Convert. Until the Release Date: (i) the Security shall only be
convertible by a Holder (or Beneficial Holder) or by the Company pursuant to
Section 9.3 of the Indenture on any day to the extent that, together with all
prior conversions under such Security or, in the case of a Global Security held
for the benefit of a Beneficial Holder, the total amount of such Security that
has been converted for the benefit of (or Beneficial Holder) does not exceed the
product of (A) 10% of the principal amount of all Securities held by such Holder
(or Beneficial Holder), and (B) the number of whole or partial calendar weeks
since the Issue Date; and (ii) a Holder (or Beneficial Holder) may only convert
such Securities to the extent of such Holders (or Beneficial Holder’s) pro rata
allocation of [___] shares of Common Stock.

    


    At no
time may the Company effect the conversion of any Securities or issue to a
Holder (or Beneficial Holder) shares of Common Stock, or a Holder (or Beneficial
Holder) convert all or a portion of the Securities into shares of Common Stock,
if following such issuance or conversion, the aggregate number of shares of
Common Stock held by any Beneficial Holder of such Securities would exceed, when
aggregated with all other shares of Common Stock then-owned by such Beneficial
Holder and all shares of Common Stock that such Beneficial Holder is then the
beneficial owner of (as determined in accordance with Section 13(d) of the
Exchange Act and the rules thereunder), the number of shares of Common Stock
that would result in such Beneficial Holder beneficially owning (as determined
in accordance with Section 13(d) of the Exchange Act and the rules thereunder)
more than 4.999% of all of the Common Stock outstanding following such
conversion.

    9. Denominations, Transfer,
Exchange. The Securities are in registered form, without coupons, in
denominations of $1,000 principal amount and integral multiples of $1,000
principal amount. The transfer of Securities may be registered and Securities
may be exchanged as provided in the Indenture. The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents. No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or similar governmental charge that may be imposed in connection with
certain transfers or exchanges.

    


    10. Persons Deemed Owners. The
registered Holder of a Security may be treated as the owner of such Security for
all purposes.

    


    11. Merger or Consolidation. The
Company shall not consolidate with or merge into, or convey, transfer or lease
all or substantially all of its properties and assets to, any person (a
“successor person”), and may not permit any person to merge into, or convey,
transfer or lease its properties and assets substantially as an entirety to, the
Company, whether in a single transaction or a series of related transactions,
unless: (a) the successor person (if any) is a corporation organized and validly
existing under the laws of any U.S. domestic jurisdiction and expressly assumes
by supplemental indenture the Company’s obligations on the Securities and under
the Indenture; and (b) immediately after giving effect to the transaction, no
default or Event of Default (as defined in the Indenture), shall have occurred
and be continuing. The Company shall deliver to the Trustee prior to the
consummation of the proposed transaction an Officers’ Certificate to the
foregoing effect and an opinion of counsel stating that the proposed transaction
and such supplemental indenture comply with the Indenture.

    


    12. Amendments, Supplements and
Waivers. Subject to certain exceptions and to compliance with the
Intercreditor Agreement, the Indenture or the Securities may be amended or
supplemented with the consent of the Holders of at least a majority in aggregate
principal amount of the outstanding Securities, and certain existing Defaults or
Events of Default may be waived with the consent of the Holders of a majority in
aggregate principal amount of the Securities then outstanding. In accordance
with the terms of the Indenture, subject to compliance with the Intercreditor
Agreement, the Company, with the consent of the Trustee, may amend or supplement
the Indenture or the Securities without notice to or the consent of any
Securityholder: (i) to comply with Section 4.2 and Section 9.13 of the
Indenture; (ii) to grant additional security for the obligations of the Company
in respect of the Securities; (iii) to surrender any right or power conferred
upon the Company; (iv) to add to the covenants of the Company described in this
Indenture for the benefit of the Holders; and (v) to make provisions with
respect to adjustments to the Conversion Rate as required by the Indenture (but
not to increase the Conversion Rate). In addition, the Company and the Trustee
may enter into a Indenture without the consent of Holders of the Securities to
cure any ambiguity, defect, omission or inconsistency in the Indenture in a
manner that does not, individually or in the aggregate with all other
modifications made or to be made to the Indenture, adversely affect the rights
of any Holder.

    


    13. Defaults and Remedies. If an
Event of Default, with respect to Securities at the time outstanding occurs and
is continuing (excluding an Event of Default referred to in Sections 5.1(g) or
(h)) with respect to the Company, then in every such case, subject to
restrictions set forth in the Intercreditor Agreement, the Trustee or the
Holders of not less than 25% in principal amount of the outstanding Securities
may declare the principal amount of and accrued and unpaid interest, if any, on
all of the Securities to be due and payable immediately, by a notice in writing
to the Company (and to the Trustee if given by Holders), and upon any such
declaration such principal amount and accrued and unpaid interest, if any, shall
become immediately due and payable. If an Event of Default specified in Sections
5.1(g) or (h) with respect to the Company shall occur, the principal amount of
and accrued and unpaid interest, if any, on all outstanding Securities shall
ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

    


    Holders
may not enforce the Indenture or the Securities except as provided in the
Indenture and subject to compliance with the Intercreditor Agreement. The
Trustee may require indemnity reasonably satisfactory to it before it enforces
the Indenture or the Securities. Subject to compliance with the Intercreditor
Agreement, the Holders of a majority in aggregate principal amount of the
Securities then outstanding may direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law the Indenture or the Intercreditor Agreement,
is unduly prejudicial to the rights of other Holders or would involve the
Trustee in personal liability unless the Trustee is offered indemnity reasonably
satisfactory to it; provided, that the Trustee
may take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

    If a
Default or Event of Default occurs and is continuing as to which the Trustee has
received notice pursuant to the provisions of the Indenture, or as to which a
Responsible Officer of the Trustee shall have actual knowledge, the Trustee
shall mail to each Holder a notice of the Default or Event of Default within
thirty (30) days after it occurs unless such Default or Event of Default has
been cured or waived. Except in the case of a Default or Event of Default in
payment of any amounts due with respect to any Security, the Trustee may
withhold the notice if, and so long as it in good faith determines that,
withholding the notice is in the best interests of Holders. The Company must
deliver to the Trustee an annual compliance certificate.

    


    14. Trustee Dealings with the
Company. The Trustee under the Indenture, or any banking institution
serving as successor Trustee thereunder, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for, the
Company or its Affiliates, and may otherwise deal with the Company or its
Affiliates, as if it were not Trustee.

    


    15. No Recourse Against Others. No
past, present or future director, officer, employee or stockholder, as such, of
the Company shall 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. Each Holder, by accepting a
Security, 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 authenticated by the manual signature of the Trustee or
an authenticating agent in accordance with the Indenture.

    


    17. Abbreviations. Customary
abbreviations may be used in the name of a Holder or an assignee, such as: TEN
COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint
tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (Uniform Gifts to Minors Act).
