                                       OF

                           LOCKHEED MARTIN CORPORATION

(Incorporated under the laws of Maryland, August 26, 1994, and herein referred
to as the "Corporation")

                                    ARTICLE I

                                  STOCKHOLDERS

     Section 1.01. ANNUAL MEETINGS. The Corporation shall hold an annual meeting
of stockholders for the election of directors and the transaction of any
business within the powers of the Corporation at such date during the month of
April in each year as shall be determined by the Board of Directors. Subject to
Article I, Section 1.11 of these Bylaws, any business of the Corporation may be
transacted at such annual meeting. Failure to hold an annual meeting at the
designated time shall not, however, invalidate the corporate existence or affect
otherwise valid corporate acts.

     Section 1.02. SPECIAL MEETINGS. At any time in the interval between annual
meetings, special meetings of the stockholders may be called by the Chairman of
the Board, Chief Executive Officer, or by the Board of Directors or by the
Executive Committee by vote at a meeting or in writing with or without a
meeting. Special meetings of stockholders shall also be called by the Secretary
of the Corporation on the written request of stockholders entitled to cast at
least a majority of all the votes entitled to be cast at the meeting.

     Section 1.03. PLACE OF MEETINGS. All meetings of stockholders shall be held
at such place within the United States as may be designated in the notice of
meeting.

     Section 1.04. NOTICE OF MEETINGS. Not less than thirty (30) days nor more
than ninety (90) days before the date of every stockholders' meeting, the
Secretary shall give to each stockholder entitled to vote at such meeting and
each other stockholder entitled to notice of the meeting, written or printed
notice stating the time and place of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, either by mail
or by presenting it to him or her personally or by leaving it at his or her
residence or usual place of business. If mailed, such notice shall be deemed to
be given when deposited in the United States mail addressed to the stockholder
at his or her post office address as it appears on the records of the
Corporation, with postage thereon prepaid. Notwithstanding the foregoing
provision for notice, a waiver of notice in writing, signed by the person or
persons entitled to such notice and filed with the records of the meeting,
whether before or after the holding thereof, or actual attendance at the meeting
in person or by proxy, shall be deemed equivalent to the giving of such notice
to such

<PAGE>

persons. Any meeting of stockholders, annual or special, may adjourn from time
to time without further notice to a date not more than one hundred twenty (120)
days after the original record date at the same or some other place.

     Section 1.05. CONDUCT OF MEETINGS. Each meeting of stockholders shall be
conducted in accordance with such rules and procedures as the Board of Directors
may determine subject to the requirements of applicable law and the Charter. The
Chairman of the Board, or in his or her absence the Chief Executive Officer, or
in their absence the person designated in writing by the Chairman of the Board,
or if no person is so designated, then a person designated by the Board of
Directors, shall preside as chairman of the meeting; if no person is so
designated, then the meeting shall choose a chairman by a majority of all votes
cast at a meeting at which a quorum is present. The Secretary or in the absence
of the Secretary a person designated by the chairman of the meeting shall act as
secretary of the meeting.

     Section 1.06. QUORUM. At any meeting of stockholders, the presence in
person or by proxy of stockholders entitled to cast a majority of the votes
thereat shall constitute a quorum; but this section shall not affect any
requirement under statute or under the Charter of the Corporation for the vote
necessary for the adoption of any measure. In the absence of a quorum, the
stockholders present in person or by proxy, by majority vote and without further
notice, may adjourn the meeting from time to time to a date not more than 120
days after the original record date until a quorum shall attend. At any such
adjourned meeting at which a quorum shall be present, any business may be
transacted which might have been transacted at the meeting as originally
notified.

     Section 1.07. VOTES REQUIRED. Unless applicable law or the Charter of the
Corporation provides otherwise, at a meeting of stockholders, the vote of a
majority of the votes entitled to be cast at a meeting, duly called and at which
a quorum is present, shall be required to take or authorize action upon any
matter which may properly come before the meeting. Unless the Charter provides
for a greater or lesser number of votes per share or limits or denies voting
rights, each outstanding share of stock, regardless of class, shall be entitled
to one vote on each matter submitted to a vote at a meeting of stockholders; but
no share shall be entitled to any vote if any installment payable thereon is
overdue and unpaid.

     Section 1.08. PROXIES. A stockholder may vote shares of the Corporation's
capital stock that are entitled to be voted and are owned of record by such
stockholder either in person or by proxy in any manner permitted by Section
2-507 of the Maryland General Corporation Law, as in effect from time to time.
No proxy shall be valid more than eleven (11) months after its date, unless
otherwise provided in the proxy.

     Section 1.09. LIST OF STOCKHOLDERS. At each meeting of stockholders, a true
and complete list of all stockholders entitled to vote at such meeting, stating
the number and class of shares held by each, shall be furnished by the
Secretary.

     Section 1.10. INSPECTORS OF ELECTION. In advance of any meeting of
stockholders, the Board of Directors may appoint Inspectors of Election to act
at such meeting or at

<PAGE>

any adjournment or adjournments thereof. If such Inspectors are not so appointed
or fail or refuse to act, the chairman of any such meeting, upon the demand of
stockholders present in person or by proxy entitled to cast 25% of all the votes
entitled to be cast at the meeting, shall make such appointments.

     If there are three (3) or more Inspectors of Election, the decision, act or
certificate of a majority shall be effective in all respects as the decision,
act or certificate of all. The Inspectors of Election shall determine the number
of shares outstanding, the voting power of each, the shares represented at the
meeting, the existence of a quorum, the authenticity, validity and effect of
proxies; shall receive votes, ballots, assents or consents, hear and determine
all challenges and questions in any way arising in connection with the vote,
count and tabulate all votes, assents and consents, and determine the result;
and do such acts as may be proper to conduct the election and the vote with
fairness to all stockholders. On request, the Inspectors shall make a report in
writing of any challenge, question or matter determined by them, and shall make
and execute a certificate of any fact found by them.

     No such Inspector need be a stockholder of the Corporation.

     Section 1.11. DIRECTOR NOMINATIONS AND STOCKHOLDER BUSINESS.

     (a) Nominations and Stockholder Business at Annual Meetings of
Stockholders. Nominations of persons for election to the Board of Directors of
the Corporation and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (i) pursuant to
the Corporation's notice of meeting, (ii) by or at the direction of the Board of
Directors or (iii) by any stockholder of the Corporation who was a stockholder
of record at the time of giving of notice provided for in this Section 1.11(a),
who is entitled to vote at the meeting and who complied with the notice
procedures set forth in this Section 1.11(a).

     For nominations or other business to be properly brought before an annual
meeting by a stockholder pursuant to clause (iii) of paragraph (a) of this
Section 1.11, the stockholder must have given timely notice thereof in writing
to the Secretary of the Corporation. To be timely, a stockholder's notice shall
be delivered to the Secretary at the principal executive offices of the
Corporation not less than ninety (90) days nor more than one-hundred twenty
(120) days prior to the first anniversary of the date of mailing of the notice
for the preceding year's annual meeting; provided, however, that in the event
that the date of mailing of the notice for the annual meeting is advanced or
delayed by more than thirty (30) days from the anniversary date of mailing of
the notice for the preceding year's annual meeting, notice by the stockholder to
be timely must be so delivered not earlier than the one-hundred twentieth
(120th) day prior to the date of mailing of the notice for such annual meeting
and not later than the close of business on the later of the ninetieth (90th)
day prior to the date of mailing of the notice for such annual meeting or the
tenth (10th) day following the day on which public announcement of the date of
mailing of the notice for such meeting is first made. Such stockholder's notice
shall set forth (i) as to each person whom the stockholder proposes to nominate
for election or reelection as a director, (A) the name, age, business address
and residence address of such person, (B) the class and number of shares of
capital stock of the Corporation that are beneficially owned by such person, and
(C) all other information

<PAGE>

relating to such person that is required to be disclosed in solicitations of
proxies for election of directors in an election contest, or is otherwise
required, in each case pursuant to Regulation 14A (or any successor provision)
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(including such person's written consent to being named in the proxy statement
as a nominee and to serving as a director if elected); (ii) as to any other
business that the stockholder proposes to bring before the meeting, a
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder (including any anticipated benefit to the
stockholder therefrom) and of each beneficial owner, if any, on whose behalf the
proposal is made; and (iii) as to the stockholder giving the notice and each
beneficial owner, if any, on whose behalf the nomination or proposal is made,
(x) the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (y) the class and number
of shares of stock of the Corporation which are owned beneficially and of record
by such stockholder and such beneficial owner.

     Notwithstanding anything in this paragraph (a) of this Section 1.11 to the
contrary, in the event that Section 2.02 of these Bylaws is amended, altered or
repealed so as to increase or decrease the maximum or minimum number of
directors and there is no public announcement of such action at least
one-hundred (100) days prior to the first anniversary of the preceding year's
annual meeting, a stockholder's notice required by this Section 1.11(a) shall
also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary at
the principal executive offices of the Corporation not later than the close of
business on the tenth (10/th/) day following the day on which such public
announcement is first made by the Corporation.

     (b) Director Nominations and Stockholder Business at Special Meetings of
Stockholders. Only such business shall be conducted at a special meeting of
stockholders as shall have been brought before the meeting pursuant to the
Corporation's notice of meeting. Nominations of persons for election to the
Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected (i) pursuant to the Corporation's notice of meeting,
(ii) by or at the direction of the Board of Directors or (iii) provided that the
Board of Directors has determined that directors shall be elected at such
special meeting, by any stockholder of the Corporation who is a stockholder of
record at the time of giving of notice provided for in this Section 1.11, who is
entitled to vote at the meeting and who complied with the notice procedures set
forth in this Section 1.11. In the event the Corporation calls a special meeting
of stockholders for the purpose of electing one or more directors to the Board,
any such stockholder may nominate a person or persons (as the case may be) for
election to such position(s) as specified in the Corporation's notice of
meeting, if the stockholder's notice required by paragraph (a) of this Section
1.11 shall be delivered to the Secretary at the principal executive offices of
the Corporation not earlier than the one-hundred twentieth (120/th/) day prior
to such special meeting and not later than the close of business on the later of
the ninetieth (90/th/) day prior to such special meeting or the tenth (10/th/)
day following the day on which public announcement is first made of the date of
the special meeting and of the nominees proposed by the Board of Directors to be
elected at such meeting.

     (c) General. Only such persons who are nominated in accordance with the
procedures set forth in this Section 1.11 and Article II, Section 2.04 shall be
eligible to serve as directors and

<PAGE>

only such business shall be conducted at a meeting of stockholders as shall have
been brought before the meeting in accordance with the procedures set forth in
this Section 1.11. The chairman of the meeting shall have the power and duty to
determine whether a nomination or any business proposed to be brought before the
meeting was made or proposed, as the case may be, in accordance with the
procedures set forth in this Section 1.11 and, if any proposed nomination or
business is not in compliance with this Section 1.11, to declare that such
defective nomination or proposal be disregarded.

     For purposes of this Section 1.11, (a) the "date of mailing of the notice"
shall mean the date of the proxy statement for the solicitation of proxies for
election of directors and (b) "public announcement" shall mean disclosure (i) in
a press release reported by the Dow Jones New Service, Associated Press or
comparable news service or (ii) in a document publicly filed by the Corporation
with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d)
of the Exchange Act.

     Notwithstanding the foregoing provisions of this Section 1.11, a
stockholder shall also comply with all applicable requirements of state law and
of the Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Section 1.11. Nothing in this Section 1.11 shall be
deemed to affect any rights of stockholders to request inclusion of proposals,
nor the right of the Corporation to omit a proposal from, in the Corporation's
proxy statement pursuant to Rule 14a-8 (or any successor provision) under the
Exchange Act.

                                   ARTICLE II

                               BOARD OF DIRECTORS

     Section 2.01. POWERS. The business and affairs of the Corporation shall be
managed under the direction of its Board of Directors. The Board of Directors
may exercise all the powers of the Corporation, except such as are by statute or
the Charter or the Bylaws conferred upon or reserved to the stockholders.

     Section 2.02. NUMBER OF DIRECTORS. The number of directors of the
Corporation shall be not less than twelve (12) nor more than twenty-five (25).
By vote of a majority of the Board of Directors, the number of directors may be
increased or decreased, from time to time, within the limits above specified;
provided, however, that except as set forth in the Charter of the Corporation,
the tenure of office of a director shall not be affected by any decrease in the
number of directors so made by the Board.

     Section 2.03. ELECTION OF DIRECTORS. Except as set forth in the Charter of
the Corporation, the members of the Board of Directors shall be elected each
year at the annual meeting of stockholders, and each director shall hold office
until the next annual meeting of stockholders held after his or her election and
until his or her successor will have been elected and qualified. No person,
other than a person granted an exemption from this provision by the Board of
Directors,

<PAGE>

shall be eligible to be elected as a director for a term which expires after the
first annual meeting of stockholders after he or she reaches the age of 72
years.

     Section 2.04. CHAIRMAN OF THE BOARD. The Board of Directors shall designate
from its membership a Chairman of the Board, who shall preside at all meetings
of the stockholders and of the Board of Directors. He may sign with the
Secretary or an Assistant Secretary certificates of stock of the Corporation,
and he shall perform such other duties as may be prescribed by the Board of
Directors.

     Section 2.05. REMOVAL. Any director or the Board of Directors may be
removed from office as a director at any time, but only for cause, by the
affirmative vote at a duly called meeting of stockholders of at least 80% of the
votes which all holders of the then outstanding shares of capital stock of the
Corporation would be entitled to cast at an annual election of directors, voting
together as a single class.

     Section 2.06. VACANCIES. Vacancies in the Board of Directors, except for
vacancies resulting from an increase in the number of directors, shall be filled
only by a majority vote of the remaining directors then in office, though less
than a quorum, except that vacancies resulting from removal from office by a
vote of the stockholders may be filled by the stockholders at the same meeting
at which such removal occurs. Vacancies resulting from an increase in the number
of directors shall be filled only by a majority vote of the Board of Directors.
Any director elected to fill a vacancy shall hold office until the next annual
meeting of stockholders and until his or her successor will have been elected
and qualified.

of a new certificate in place thereof upon such terms and conditions as it may
deem advisable; or the Board of Directors may delegate such power to any officer
or officers or agents of the Corporation; but the Board of Directors or such
officer or officers, in their discretion, may refuse to issue such new
certificate save upon the order of some court having jurisdiction in the
premises.

                                   ARTICLE VI

                                 INDEMNIFICATION

     Section 6.01. INDEMNIFICATION OF DIRECTORS, OFFICERS, AND EMPLOYEES. The
Corporation shall indemnify and hold harmless to the fullest extent permitted
by, and under, applicable law as it presently exists and as is further set forth
in Section 6.02 below or as may hereafter be amended any person who is or was a
director, officer or employee of the Corporation or who is or was serving at the
request of the Corporation as a director, officer or employee of another
corporation or entity (including service with employee benefit plans), who by
reason of this status or service in that capacity was, is, or is threatened to
be made a party or is otherwise involved in any action, suit or proceeding,
whether civil, criminal, administrative, or investigative. Such indemnification
shall be against all liability and loss suffered and expenses (including, but
not limited to, attorneys' fees, judgments, fines, penalties, and amounts paid
in settlement) actually and reasonably incurred by the individual in connection
with such proceeding; provided, however, that the Corporation shall not be
required to indemnify a person in connection with an action, suit or proceeding
initiated by such person unless the action, suit or proceeding was authorized by
the Board of Directors of the Corporation.

     Section 6.02. STANDARD. Maryland General Corporation Law Section 2-418, on
August 29, 1994, provided generally that a corporation may indemnify any
individual made a party to a proceeding by reason of service on behalf of the
corporation unless it is established that:

          (i)   The act or omission of the individual was material to the matter
     giving rise to the proceeding; and

                (1) Was committed in bad faith; or

                (2) Was the result of active and deliberate dishonesty; or

          (ii)  The individual actually received an improper personal benefit in
     money, property, or services; or

          (iii) In the case of any criminal proceeding, the individual had
     reasonable cause to believe that the act or omission was unlawful.

<PAGE>

     Section 6.03. ADVANCE PAYMENT OF EXPENSES. The Corporation shall pay or
reimburse reasonable expenses in advance of a final disposition of the
proceeding and without requiring a preliminary determination of the ultimate
entitlement to indemnification provided that the individual first provides the
Corporation with: (a) a written affirmation of the individual's good faith
belief that the individual meets the standard of conduct necessary for
indemnification under the laws of the State of Maryland; and (b) a written
undertaking by or on behalf of the individual to repay the amount advanced if it
shall ultimately be determined that the applicable standard of conduct has not
been met.

     Section 6.04. GENERAL. The Board of Directors, by resolution, may authorize
the management of the Corporation to act for and on behalf of the Corporation in
all matters relating to indemnification within any such limits as may be
specified from time to time by the Board of Directors, all consistent with
applicable law.

     The rights conferred on any person by this Article VI shall not be
exclusive of any other rights which such person may have or hereafter acquire
under any statute, provision of the Charter of the Corporation, these Bylaws,
agreement, vote of the stockholders or disinterested directors or otherwise.

     Repeal or modification of this Article VI or the relevant law shall not
affect adversely any rights or obligations then existing with respect to any
facts then or theretofore existing or any action, suit or proceeding theretofore
or thereafter brought or threatened based in whole or in part upon any such
facts.

                                   ARTICLE VII

                                SUNDRY PROVISIONS

     Section 7.01. SEAL. The corporate seal of the Corporation shall bear the
name of the Corporation and the words "Incorporated 1994 Maryland" and
"Corporate Seal."

     Section 7.02. VOTING OF STOCK IN OTHER CORPORATIONS. Any shares of stock in
other corporations or associations, which may from time to time be held by the
Corporation, may be represented and voted at any of the stockholders' meetings
thereof by the Chairman or President of the Corporation or by proxy or proxies
appointed by the Chairman or President of the Corporation. The Board of
Directors or Chairman, however, may by resolution or delegation appoint some
other person or persons to vote such shares, in which case such person or
persons shall be entitled to vote such shares upon the production of a certified
copy of such resolution or delegation.

     Section 7.03. AMENDMENTS. The Board of Directors shall have the exclusive
power, at any regular or special meeting thereof, to make and adopt new Bylaws,
or to amend, alter, or repeal any Bylaws of the Corporation, provided such
revisions are not inconsistent with the Charter or statute.<PAGE>

     WHEREAS, for its lawful corporate purposes, the Company deems it necessary

     NOW, THEREFORE, THIS INDENTURE WITNESSETH:

     For and in consideration of the premises and the purchase of the Securities
by the Holders thereof, it is mutually covenanted and agreed by the Company and
by the Trustee, for the equal and proportionate benefit of all Holders of the
Securities, as follows:

                                   ARTICLE 1
             Definitions and Other Provisions of General Application

     Section 1.01. Certain Terms Defined.

     (a) Definitions.

     "Accreted Interest" means, for any Interest Period for any Security as of
any date of determination, (i) the Accreted Principal Amount of such Security at
the beginning of the Interest Period in which such date occurs, multiplied by
(ii) the Applicable Yield for such Interest Period, multiplied by (iii) the
quotient of the actual number of days elapsed from and including the first day
of such Interest Period, to but excluding the date of determination divided by
360; provided that the Accreted Interest for any full Interest Period shall be
calculated by reference to the actual number of days in such Interest Period
divided by 360.

     "Accreted Principal Amount" means, for any Security as of any date of
determination, (i) the Original Principal Amount of such Security, plus (ii) the
sum of the Accreted Interest for each Interest Period concluding on or prior to
such date, plus (iii) the Accreted Interest for the Interest Period in which
such date occurs as of the date of determination.

     "Additional Interest" has the meaning specified in the Registration Rights
Agreement.

<PAGE>

     "Affiliate" of any specified person means any other person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified person. For the purposes of this definition,
"control" when used with respect to any specified person means the power to
direct or cause the direction of the management and policies of such person,
directly or indirectly, whether through the ownership of voting securities, by
contract or otherwise; and the terms "controlling" and "controlled" have
meanings correlative to the foregoing.

     "Applicable Stock Price" means, in respect of a Conversion Date, the
average of the Last Reported Sale Prices per share of Common Stock over the
five-Trading Day period starting the third Trading Day following such Conversion
Date.

     "Applicable Yield" means (1) prior to August 15, 2008, 0% and (2) from and
after August 15, 2008, for any Interest Period, a rate equal to 3-Month LIBOR
determined on the LIBOR Determination Date relating to the Interest Reset Date
for such Interest Period, minus 0.25% provided that in no event shall the
Applicable Yield be less than 0%.

be.

if any specified date (including a date for giving notice) on which action is to

Purchase Date) of a Security falls on a day that is not a Business Day, such
Interest Payment Date will be postponed to the next succeeding Business

Payment Date will be the Business Day immediately preceding such Interest

Fundamental Change Purchase Date of a Security would fall on a day that is not a
Business Day, the required payment of interest, if any, and principal will be
made on the next succeeding Business Day and no interest on such payment will
accrue for the period from and after the Stated Maturity, Redemption Date,
Purchase Date or Fundamental Change Purchase Date to such next succeeding
Business Day.

be tradable on The PORTAL(R) Market or as may be required for the Securities to
be tradable on any other market developed for trading of securities pursuant to
Rule 144A or as may be required to comply with any applicable law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Securities may be
listed, or to conform to usage, or to indicate any special limitations or
restrictions to which any particular Securities are subject.

     So long as the Securities are eligible for book-entry settlement with the
Depositary, or unless otherwise required by law, or otherwise contemplated by
Section 2.11(b), all of the Securities will be represented by one or more
Securities in global form registered in the name of the Depositary or the
nominee

                                       13

<PAGE>

of the Depositary (a "Global Security"). The transfer and exchange of beneficial
interests in any such Global Security shall be effected through the Depositary
in accordance with this Indenture and the applicable procedures of the
Depositary. Except as provided in Section 2.11(b), beneficial owners of a Global
Security shall not be entitled to have certificates registered in their names,
will not receive or be entitled to receive physical delivery of certificates in
definitive form and will not be considered holders of such Global Security.

     Each Global Security shall represent such of the outstanding Securities as
shall be specified therein and each shall provide that it shall represent the
aggregate Original Principal Amount of outstanding Securities from time to time
endorsed thereon and that the aggregate Original Principal Amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, redemptions, purchases or conversions of such
Securities. Any endorsement of a Global Security to reflect the amount of any
increase or decrease in the Original Principal Amount of outstanding Securities
represented thereby shall be made by the Trustee in accordance with the standing
instructions and procedures existing between the Depositary and the Trustee.

     Each Security shall be dated the date of its authentication.

     Section 2.02. Execution and Authentication. Two Officers (or one Officer
and an Assistant Treasurer or an Assistant Secretary) shall sign the Securities
for the Company by manual or facsimile signature.

     If an Officer whose signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security, the Security shall be valid
nevertheless.

     A Security shall not be valid until the Trustee manually signs the
certificate of authentication on the Security. The signature shall be conclusive
evidence that the Security has been authenticated under this Indenture.

     The Trustee shall authenticate and deliver Securities for original issue in
an aggregate Original Principal Amount of $850,000,000 (up to $1,000,000,000 if
the Initial Purchasers' option set forth in the Purchase Agreement is exercised
in full) upon a Company Order without any further action by the Company. The
Securities shall be issued only in registered form without coupons and only in
denominations of $1,000 Original Principal Amount and any integral multiple
thereof. The aggregate Original Principal Amount of Securities outstanding at
any time may not exceed the amount set forth in the first sentence of this
paragraph, subject to the parenthetical set forth therein, except as provided in
Section 2.06.

                                       14

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

     The Company shall notify the Trustee of the name and address of any such
agent. If the Company fails to maintain a Registrar, Paying Agent, Trustee or
Conversion Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 5.07. The Company or any
Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar,
Trustee, Conversion Agent or co-registrar.

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

     Section 2.04. Paying Agent to Hold Money and Securities in Trust. Except as
otherwise provided herein, on or prior to each due date of payments in respect
of any Security, the Company shall deposit with the Paying Agent a sum of money
(in immediately available funds if deposited on the due date) or, if applicable,
Common Stock sufficient to make such payments when so becoming due. The Company
shall require each Paying Agent (other than the Trustee) to agree in writing
that the Paying Agent shall hold in trust for the benefit of Holders and/or the
Trustee all money and Common Stock held by the Paying Agent for the making of
payments in respect of the Securities and shall notify the Trustee of any
default by the Company in making any such payment. At any time during the
continuance of any such default, the Paying Agent shall, upon the written
request of the Trustee, forthwith pay to the Trustee all money and Common Stock
so held in trust. If the Company, a Subsidiary or an Affiliate of either of them
acts as Paying Agent, it shall segregate the money and Common Stock held by it
as Paying Agent and hold it as a separate trust fund. The Company at any time
may require a Paying Agent to pay all money and Common Stock held by it to the
Trustee and to account for any funds and Common Stock disbursed by it. Upon
doing so, the Paying Agent shall have no further liability for the money or
Common Stock.

     Section 2.05. Transfer and Exchange. (a) Subject to Section 2.11 hereof,
upon surrender for registration or transfer of any Security, together with a
written instrument of transfer satisfactory to the Registrar duly executed by
the

                                       15

<PAGE>

Holder or such Holder's attorney duly authorized in writing, at the office or
agency of the Company designated as Registrar or co-registrar pursuant to
Section 2.03, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denomination or denominations, of a like
aggregate Original Principal Amount. The Company shall not charge a service
charge for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to pay all taxes, assessments or other governmental
charges that may be imposed in connection with the transfer or exchange of the
Securities from the Holder requesting such transfer or exchange.

     The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities in respect of which a Purchase Notice or Fundamental
Change Purchase Notice has been given and not withdrawn by the Holder thereof in
accordance with the terms of this Indenture (except, in the case of Securities
to be purchased in part, the portion thereof not to be purchased) or any
Securities for a period of 15 days before the mailing of a notice of redemption
of Securities to be redeemed.

     (b) Notwithstanding any provision to the contrary herein, so long as a
Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, shall be made
only in accordance with Section 2.11 and this Section 2.05(b). Transfers of a
Global Security shall be limited to transfers of such Global Security in whole,
or in part, to nominees of the Depositary or to a successor of the Depositary or
such successor's nominee.

     (c) Successive registrations and registrations of transfers and exchanges
as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Securities.

     (d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide
to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon transfer or
exchange of Securities.

     (e) No Registrar shall be required to make registrations of transfer or
exchange of Securities during any periods designated in the text of the
Securities or in this Indenture as periods during which such registration of
transfers and exchanges need not be made.

     (f) Prior to the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision),

                                       16

<PAGE>

if Securities are issued upon the transfer, exchange or replacement of
Securities subject to restrictions on transfer and bearing the legends on the
form of Security attached hereto as Exhibit A setting forth such restrictions
(collectively, the "Legend"), or if a request is made to remove the Legend on a
Security, the Securities so issued shall bear the Legend, or the Legend shall
not be removed, as the case may be, unless there is delivered to the Company and
the Registrar such satisfactory evidence, which shall include an Opinion of
Counsel, as may be reasonably required by the Company and the Registrar, that
neither the Legend nor the restrictions on transfer set forth therein are
required to ensure that transfers thereof comply with the provisions of Rule
144A or Rule 144 under the Securities Act or that such Securities are not
"restricted" within the meaning of Rule 144 under the Securities Act. Upon (i)
provision of such satisfactory evidence or (ii) notification by the Company to
the Trustee and Registrar of the sale of such Security pursuant to a
registration statement that is effective at the time of such sale, the Trustee,
at the written direction of the Company, shall authenticate and deliver a
Security that does not bear the Legend. If the Legend is removed from the face
of a Security and the Security is subsequently held by an Affiliate of the
Company, the Legend shall be reinstated. Any shares of Common Stock issued upon
conversion of Securities that bear the Legend shall bear a restricted legend
substantially identical to the Legend (except that such Legend shall not refer
to any shares of Common Stock issuable upon conversion of Securities).

     (g) Nothing in this Indenture or in the Securities shall prohibit the sale
or other transfer of any Securities (including beneficial interests in Global
Securities) to the Company or any of its Subsidiaries.

     Section 2.06. Replacement Securities. If (a) any mutilated Security is
surrendered to the Trustee, or (b) the Company and the Trustee receive evidence
to their satisfaction of the destruction, loss or theft of any Security, and
there is delivered to the Company and the Trustee such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its written request the
Trustee shall authenticate and deliver, in exchange for any such mutilated
Security or in lieu of any such destroyed, lost or stolen Security, a new
Security of like tenor and Original Principal Amount, bearing a number not
contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, or is about to be purchased by the
Company pursuant to Articles 12 or 13 hereof, the Company in its discretion may,
instead of issuing a new Security, pay or purchase such Security, as the case
may be.

                                       17

<PAGE>

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

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

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

     Section 2.07. Outstanding Securities; Determinations of Holders' Actions.
Securities outstanding at any time are all the Securities authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those delivered to it pursuant to Section 2.06 and those described in this
Section 2.07 as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate thereof holds the Security; provided,
however, that in determining whether the Holders of the requisite Original
Principal Amount of Securities have given or concurred in any request, demand,
authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the
Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, only Securities which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded. Subject to the foregoing,
only Securities outstanding at the time of such determination shall be
considered in any such determination (including, without limitation,
determinations pursuant to Articles 4 and 8).

     If a Security is replaced pursuant to Section 2.06, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a protected purchaser.

     If the Paying Agent holds, in accordance with this Indenture, on a
Redemption Date, or on the Business Day following a Purchase Date or a
Fundamental Change Purchase Date, or on Stated Maturity, money or securities, if
permitted hereunder, sufficient to pay Securities payable on that date, then
immediately after such Redemption Date, Purchase Date, Fundamental Change
Purchase Date or Stated Maturity, as the case may be, such Securities shall
cease

                                       18

<PAGE>

to be outstanding and interest (including Contingent Interest and Additional
Interest, if any) on such Securities shall cease to accrue; provided, that if
such Securities are to be redeemed, notice of such redemption has been duly
given pursuant to this Indenture or provision therefor satisfactory to the
Trustee has been made.

     If a Security is converted in accordance with Article 11, then from and
after the time of conversion on the Conversion Date, such Security shall cease
to be outstanding and interest (including Contingent Interest, if any) shall
cease to accrue on such Security, unless the Holder of such Security retracts
the Notice of Conversion pursuant to Section 11.02.

     Section 2.08. Temporary Securities. Pending the preparation of definitive
Securities, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.

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

     Section 2.09. Cancellation. All Securities surrendered for payment,
purchase by the Company pursuant to Article 12 and Article 13, conversion,
redemption or registration of transfer or exchange shall, if surrendered to any
person other than the Trustee, be delivered to the Trustee and shall be promptly
canceled by it. The Company or any Subsidiary may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder that the Company or any Subsidiary may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly canceled by the
Trustee. The Company may not issue new Securities to replace Securities it has
paid or delivered to the Trustee for cancellation or that any Holder has
converted pursuant to Article 11. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as

                                       19

<PAGE>

expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
practice.

     Section 2.10. Persons Deemed Owners. Prior to due presentment of a Security
for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of the Security or the payment of any Redemption Price, Purchase Price
or Fundamental Change Purchase Price in respect thereof, and interest thereon,
for the purpose of conversion and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the Trustee nor any agent
of the Company or the Trustee shall be affected by notice to the contrary.

     Section 2.11. Global Securities.

     (a) Notwithstanding any other provisions of this Indenture or the
Securities, transfers of a Global Security, in whole or in part, shall be made
only in accordance with Section 2.05 and this Section 2.11. A Global Security
may not be transferred, in whole or in part, to any Person other than the
Depositary or a nominee or any successor thereof, and no such transfer to any
such other Person may be registered; provided that this clause (a) shall not
prohibit any transfer of a Security that is issued in exchange for a Global
Security but is not itself a Global Security. No transfer of a Security to any
Person shall be effective under this Indenture unless and until such Security
has been registered in the name of such Person.

     (b) Notwithstanding any other provisions of this Indenture or the
Securities, a Global Security shall not be exchanged in whole or in part for a
Security registered in the name of any Person other than the Depositary or one
or more nominees thereof, provided that a Global Security may be exchanged for
Securities registered in the names of any person designated by the Depositary in
the event that (i) the Depositary has notified the Company that it is unwilling
or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a "clearing agency" registered under the Exchange Act, and a
successor Depositary is not appointed by the Company within 90 days or (ii) the
Company decides to discontinue the use of the system of book-entry transfer
through the Depositary (or any successor Depositary). Any Global Security
exchanged pursuant to clause (a) above shall be so exchanged in whole and not in
part. Any Security issued in exchange for a Global Security or any portion
thereof shall be a Global Security; provided that any such Security so issued
that is registered in the name of a Person other than the Depositary or a
nominee thereof shall not be a Global Security.

                                       20

<PAGE>

         (c) Securities issued in exchange for a Global Security or any portion
thereof shall be issued in definitive, fully registered form, without interest
coupons, shall have an aggregate Original Principal Amount equal to that of such
Global Security or portion thereof to be so exchanged, shall be registered in
such names and be in such authorized denominations as the Depositary shall
designate and shall bear the applicable Legends provided for herein. Any Global
Security to be exchanged in whole shall be surrendered by the Depositary to the
Trustee or the Registrar. With regard to any Global Security to be exchanged in
part, either such Global Security shall be so surrendered for exchange or, if
the Trustee is acting as custodian for the Depositary or its nominee with
respect to such Global Security, the Original Principal Amount thereof shall be
reduced, by an amount equal to the portion thereof to be so exchanged, by means
of an appropriate adjustment made on the records of the Trustee. Upon any such
surrender or adjustment, the Trustee shall authenticate and deliver the Security
issuable on such exchange to or upon the order of the Depositary or an
authorized representative thereof.

         (d) Subject to the provisions of Section 2.11(f) below, the registered
Holder may grant proxies and otherwise authorize any Person, including Agent
Members (as defined below) and persons that may hold interests through Agent
Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities.

         (e) In the event of the occurrence of any of the events specified in
Section 2.11(b) above, the Company will promptly make available to the Trustee a
reasonable supply of certificated Securities in definitive, fully registered
form, without interest coupons.

         (f) Neither any members of, or participants in, the Depositary
(collectively, the "Agent Members") nor any other Persons on whose behalf Agent
Members may act shall have any rights under this Indenture with respect to any
Global Security registered in the name of the Depositary or any nominee thereof,
or under any such Global Security, and the Depositary or such nominee, as the
case may be, may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner and holder of such Global Security
for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company or the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or such nominee, as the case may be, or impair, as
between the Depositary, its Agent Members and any other person on whose behalf
an Agent Member may act, the operation of customary practices of such Persons
governing the exercise of the rights of a holder of any Security.

         Section 2.12. Legends.

                                       21

<PAGE>

         (a) Subject to the succeeding paragraph, every Security shall be
subject to the restrictions on transfer provided in the Legend including the
delivery of a certification or an Opinion of Counsel as set forth in the Legend,
if so requested by the Company or the Registrar.

         (b) The restrictions imposed by the Legend upon the transferability of
any Security shall cease and terminate when such Security has been sold pursuant
to an effective registration statement under the Securities Act or transferred
in compliance with Rule 144 under the Securities Act (or any successor provision
thereto) or, if earlier, upon the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision). Any Security as to which such restrictions on transfer shall have
expired in accordance with their terms or shall have terminated may, upon a
surrender of such Security for exchange to the Registrar in accordance with the
provisions of this Section 2.12 (accompanied, in the event that such
restrictions on transfer have terminated by reason of a transfer in compliance
with Rule 144 or any successor provision, by an opinion of counsel having
substantial experience in practice under the Securities Act and otherwise
reasonably acceptable to the Company, addressed to the Company and the Registrar
and in form acceptable to the Company, to the effect that the transfer of such
Security has been made in compliance with Rule 144 or such successor provision),
be exchanged for a new Security, of like tenor and aggregate Original Principal
Amount, which shall not bear the restrictive Legend. The Company shall inform
the Trustee of the effective date of any registration statement registering the
Securities under the Securities Act. The Trustee and the Registrar shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the aforementioned opinion of counsel or registration statement.

         (c) As used in the preceding two paragraphs of this Section 2.12, the
term "transfer" encompasses any sale, pledge, transfer, hypothecation or other
disposition of any Security.

         Section 2.13. Payment of Interest; Interest Rights Preserved. Interest,
including Contingent Interest and Additional Interest, if any, on any Security
that is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest at the office or agency of the Company
maintained for such purpose pursuant to Section 9.02. However, the Company may
make such interest payments by check payable to or upon the written order of the
Person entitled thereto pursuant to Section 17.03, to the address of such Person
as it appears on the Security Register; provided that payment by wire transfer
of immediately available funds will be required with respect to principal of and
interest (including Contingent Interest, if any) on all Global Securities and
all

                                       22

<PAGE>

Securities of Holders of more than $25,000,000 aggregate Original Principal
Amount of Securities that have requested such method of payment and provided
wire transfer instructions to the Company or the Paying Agent at least five
Business Days prior to the applicable Interest Payment Date.

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

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

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

                                       23

<PAGE>

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

         Section 2.14. 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
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the CUSIP numbers.

         Section 2.15. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders of Securities. If the Trustee is not the
Registrar, the Company shall furnish or cause to be furnished to the Trustee on
or before each Interest Payment Date and at such other times as the Trustee may
request in writing a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Holders of Securities.

                                    ARTICLE 3

                           Satisfaction and Discharge

    Section 3.01. Discharge of Liability on Securities. When (i) the Company
delivers to the Trustee or any Paying Agent all outstanding Securities (other
than Securities replaced pursuant to Section 2.06 of the Indenture) for
cancellation or (ii) all outstanding Securities have become due and payable,
whether at Stated Maturity, any Redemption Date, any Purchase Date, a
Fundamental Change Purchase Date, or upon conversion or otherwise, and the
Company deposits with the Trustee or any Paying Agent cash or, if expressly
permitted by the terms of the Securities, Common Stock sufficient to pay all
amounts due and owing on all outstanding Securities (other than Securities
replaced pursuant to Section 2.06), and if in either case the Company pays all
other sums payable hereunder by the Company, then this Indenture shall, subject
to Section 5.07, cease to be of further effect, except for the indemnification
of the Trustee, which shall survive such satisfaction and discharge. The Trustee
shall join in the execution of a document prepared by the Company acknowledging
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and Opinion of Counsel and at the
reasonable cost and expense of the Company.

Securities or this Indenture.

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

         Section 4.05. Trustee May File Proofs of Claim. The Trustee may file

behalf of the Holders in any election of a trustee in bankruptcy or other person
performing similar functions.

         ratably, without preference or priority of any kind, according to the
         amounts due and payable on such Securities; and

                 THIRD: To the payment of the remainder, if any, to the Company

proceeding, judicial or otherwise, with respect to this Indenture, or for the

         to the Trustee of a continuing Event of Default with respect to the
         Securities held by that Holder;

                  (ii)  the Holders of not less than 25% in aggregate Original
         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;

                  (iii) such Holder or Holders shall have offered to the Trustee
         reasonable indemnity satisfactory to it as it may require against the
         costs, expenses and liabilities to be incurred in compliance with such
         request;

                  (iv)  no direction inconsistent with such written request
         shall have been given to the Trustee pursuant to Section 4.11 during
         such 60-day period by the Holders of a majority in Original Principal
         Amount of the outstanding Securities; and

                  (v)   the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity shall have failed to institute
         any such proceeding.

any Security shall have the right, which is absolute and unconditional, to

Price, Fundamental Change Purchase Price and interest (including Contingent
Interest and Additional Interest, if any) on such Security after the respective
due dates expressed in such Security, and to convert the Securities in

such payment on or

                                       28

<PAGE>

after such respective dates, and such rights shall not be impaired without the
consent of such Holder.

         Section 4.09. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in the last paragraph of Section 2.06, 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.

         Section 4.10. 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 4 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 4.11. Control by Holders. The Holders of a majority in
aggregate Original 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, however, that

                  (i)   such direction shall not be in conflict with any rule of
         law or with this Indenture,

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

                  (iii) such direction is not unduly prejudicial to the rights
         of Holders not taking part in such direction, and

                  (iv)  such direction would not involve the Trustee in personal
         liability, as the Trustee, upon being advised by counsel, shall
         reasonably determine.

         Section 4.12. Waiver of Past Defaults.

         (a) Before a declaration that the Accreted Principal Amount of the
Securities and any accrued or unpaid interest (including Contingent Interest and

                                       29

<PAGE>

Additional Interest, if any) shall be due and payable immediately is made
pursuant to Section 4.02(a), the Holders of at least a majority in aggregate
Original Principal Amount of the outstanding Securities may on behalf of the
Holders of all the Securities by notice to the Trustee waive any past default
hereunder with respect to such Securities and its consequences, except a Default
that is (i) an Event of Default described in Section 4.01(a) or Section 4.01(b)
or (ii) in respect of a covenant or provision hereof which under Article 8
cannot be modified or amended without the consent of the Holder of each
outstanding Security.

         (b) 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, and the Company, the Trustee and Holders shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

         Section 4.13. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Security by the Holder's 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 and expenses, 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 Original Principal Amount of
the outstanding Securities, or to any suit instituted by any Holder pursuant to
Section 4.08. This Section 4.13 shall be in lieu of Section 315(e) of the TIA
and such Section 315(e) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

irrespective of whether the Trustee has been advised of the likelihood of such
loss or damage and regardless of the form of action.

     (i) The Trustee shall not be deemed to have notice of any Default or Event

which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not suspended.

     Section 5.03. Individual Rights of Trustee, etc. 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 any of its Affiliates with the same

Securities and is continuing and if it is known to the Trustee, the Trustee
shall mail to each Holder of Securities of that series notice of the Default

reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it. Such expenses shall include the reasonable compensation and
expenses of the Trustee's agents and counsel. The Company shall indemnify the
Trustee against any and all loss, liability, damage, claim or expense, including
taxes (other than those based upon, measured by or determined by the income of

trust to pay principal of and interest, if any, on particular Securities.

Event of Default specified in Section 4.01(e) or Section 4.01(f), the expenses

administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section shall survive the termination of this
Indenture and the resignation or removal of the Trustee.

to the Securities by so notifying the Company. The Holders of a majority in

of trustee for any reason, the Company shall promptly appoint a successor
Trustee.

                                       34

     A 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 for the benefit of the
series with respect to which it is retiring to the successor Trustee, the
resignation or removal of the retiring Trustee shall then become effective, and
the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture with respect to that series. A successor Trustee
shall mail notice of its succession to each Holder of the Securities.

     If a successor Trustee with respect to the Securities does not take office

Trustee, the Company or the Holders of a majority in principal amount of the
Securities may petition any court of competent jurisdiction, at the expense of
the Company in the case of the Trustee, for the appointment of a successor
Trustee.

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

     If there are two or more Trustees at any time under this Indenture, each
will be the Trustee of a separate trust held under this Indenture for the
benefit of the series of Securities for which it is acting as Trustee and the
rights and obligations of each Trustee will be determined as if it were acting
under a separate indenture.

     Section 5.09. Successor Trustee by Merger, etc. If the Trustee consolidates

     Section 8.03. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article 8 or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be provided with, and (subject to Section 5.01)
shall be fully protected in relying upon, an Opinion of Counsel and an Officers'
Certificate stating that the execution of such supplemental indenture is

Trustee's own rights, duties or immunities under this Indenture or otherwise.

the Company at the latest on the day such payment is due. Accreted Principal
Amount, Redemption Price, Purchase Price, Fundamental Change Purchase Price and
interest (including Contingent Interest and Additional Interest, if any), shall
be considered paid on the applicable date due if on such date (or, in the case
of a Purchase Price or Fundamental Change Purchase Price, on the Business Day
following the applicable Purchase Date or Fundamental Change Purchase Date, as
the case may be) the Trustee or the

                                       40

<PAGE>

Paying Agent holds, in accordance with this Indenture, money or securities, if
permitted hereunder, sufficient to pay all such amounts then due.

     Section 9.02. Maintenance of Office or Agency. The Company shall maintain
an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent
where the Securities may be presented or surrendered for payment, where the
Securities may be surrendered for registration of transfer or exchange, where
the Securities may be surrendered for purchase, redemption or conversion and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and 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 thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands. The Corporate Trust Office of the Trustee, shall initially be such
office or agency for all of the aforesaid purposes.

file with the Trustee promptly at the end of each calendar year (i) a written
notice specifying the amount of Tax Original Issue Discount (including daily

Discount as may then be reasonably requested by the Trustee and relevant under
the Internal Revenue Code of 1986, as amended from time to time or the Treasury
Regulations promulgated thereunder.

deliver such further instruments and do such further acts as may be reasonably

effectively the purposes of this Indenture.

     (b)  On any Interest Payment Date on which Additional Interest is payable,
the Company shall issue a press release stating the amount of such Additional
Interest and setting forth the manner in which such amount was calculated, and
publish such information on its website on the World Wide Web.

     Section 9.06. Contingent Debt Treatment. The Company agrees, and by
acceptance of a beneficial interest in a Security each Holder and any beneficial
owner of a Security shall be deemed to agree, to treat, for United States
federal income tax purposes, the Securities as debt instruments that are subject
to Treasury Regulation Section 1.1275-4 or any successor provision (the
"contingent debt regulations") and to be bound (in the absence of an
administrative determination or judicial ruling to the contrary) by the
Company's determination of the comparable yield and projected payment schedule
within the meaning of the contingent debt regulations. Holders or beneficial
owners may obtain the issue price, amount of Tax Original Issue Discount, issue
date, yield to maturity, comparable yield and a copy of the projected payment
schedule, determined by the Company pursuant to the contingent debt regulations,
by submitting a written request for it to the Company at the following address:
Lockheed Martin Corporation, 6801 Rockledge Drive, Bethesda, Maryland, 20817,
Attention: Treasurer.

     The Company acknowledges and agrees, and by acceptance of a beneficial
interest in a Security each Holder and any beneficial owner of a Security shall
be deemed to acknowledge and agree, that (i) the comparable yield means the
annual yield the Company would pay, as of the issue date, on a noncontingent,
nonconvertible, fixed-rate debt instrument with terms and conditions otherwise
similar to those of the Securities and (ii) the comparable yield and the
projected payment schedule that a Holder or beneficial owner may obtain as
described above do not constitute a representation by the Company regarding the
actual amounts that will be paid on the Securities or the value of the Common
Stock into which the Securities may be converted.

     Section 9.07. Reports by Company. The Company shall file with the Trustee,
within 15 days after it files such annual and quarterly reports, information,
documents and other reports with the Commission, copies of its annual report and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may by rules and regulations prescribe)
which the Company is required to file with the Commission pursuant to Section 13
or 15(d) of the Exchange Act. The Company also shall comply with the other
provisions of TIA Section 314(a).

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of

                                       42

<PAGE>

its covenants hereunder (as to which the Trustee is entitled to rely exclusively
on Officers' Certificates).

     If at any time while any of the Securities are "restricted securities"
within the meaning of Rule 144, the Company is no longer subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company
will prepare and will furnish to any Holder, any beneficial owner of Securities
and any prospective purchaser of Securities designated by a Holder or a
beneficial owner of Securities, promptly upon request, the information required
pursuant to Rule 144A(d)(4) (or any successor thereto) under the Securities Act
in connection with the offer, sale or transfer of Securities.

     Section 9.08. Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate, one of the signatories to which is the chief executive,
chief accounting or chief financial officer, stating whether or not the signers
know of any default by the Company in performing its covenants in this Article
9. If they do know of such a default, the certificate shall describe the
default. The certificate need not comply with Section 17.05.

                                   ARTICLE 10
                            Redemption of Securities

     Section 10.01. Right to Redeem; Notices to Trustee. Prior to August 15,
2008, the Securities shall not be redeemable at the option of the Company.
Beginning on August 15, 2008 and until the Stated Maturity, the Securities are
redeemable for cash as a whole, or from time to time in part, at the option of
the Company at the Redemption Price; provided that if the Redemption Date is an
Interest Payment Date, accrued and unpaid interest (including Contingent
Interest or Additional Interest, if any) shall be paid to the Holder of record
as of the applicable Regular Record Date, rather than to the Holder presenting
the Security for redemption. If the Company elects to redeem Securities, it
shall notify the Trustee in writing of the Redemption Date, the Original
Principal Amount of Securities to be redeemed and the Redemption Price.

     The Company shall give the notice by mail to the Trustee provided for in
this Section 10.01 by a Company Order not less than 50 days before the
Redemption Date.

     Section 10.02. Selection of Securities to Be Redeemed. If less than all the
Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata or by lot or by any other method the Trustee considers fair
and appropriate (so long as such method is not prohibited by the rules of any
stock exchange on which the Securities are then listed). The Trustee shall make
the

                                       43

<PAGE>

selection at least 20 days but not more than 60 days before the Redemption Date
from outstanding Securities not previously called for redemption. The Trustee
may select for redemption portions of the Original Principal Amount of
Securities that have denominations larger than $1,000. Securities and portions
of them the Trustee selects shall be in Original Principal Amounts of $1,000 or
an integral multiple of $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be redeemed.

     If any Security selected for partial redemption is converted in part before
the Business Day immediately preceding the Redemption Date, the converted
portion of such Security shall be deemed (so far as may be) to be the portion
selected for redemption. Securities which have been converted during a selection
of Securities to be redeemed may be treated by the Trustee as outstanding for
the purpose of such selection.

     Section 10.03. Notice of Redemption. (a) At least 20 days but not more than
60 days before a Redemption Date, the Company shall mail a notice of redemption
by first-class mail, postage prepaid, to each Holder of Securities to be
redeemed.

     (b)  The notice shall identify the Securities to be redeemed (including the
CUSIP numbers) and shall at a minimum state:

          (i)    the Redemption Date;

          (ii)   the Redemption Price;

          (iii)  the Conversion Rate;

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

          (v)    that Securities called for redemption may be converted at any
     time before the close of business on the Business Day immediately preceding
     the Redemption Date;

          (vi)   that Holders who want to convert Securities must satisfy the
     requirements set forth in the applicable provisions of the Securities;

          (vii)  whether the Company will deliver cash, Common Stock or a
     combination of cash and Common Stock in the event a Holder converts
     Securities called for redemption;

                                       44

<PAGE>

          (viii) that Securities called for redemption must be surrendered to
     the Paying Agent to collect the Redemption Price;

          (ix)   if fewer than all the outstanding Securities are to be
     redeemed, the certificate number and Original Principal Amounts of the
     particular Securities to be redeemed;

          (x)    that, unless the Company defaults in making payment of such
     Redemption Price, interest (including Contingent Interest and Additional
     Interest, if any) on Securities called for redemption will cease to accrue
     on and after the Redemption Date; and

          (xi)   the CUSIP number of the Securities.

     (c)  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense, provided that the
Company makes such request at least three Business Days prior to such notice of
redemption.

     Section 10.04. Effect of Notice of Redemption. Once notice of redemption is
given, Securities called for redemption become due and payable on the Redemption
Date and at the Redemption Price stated in the notice, except for Securities
which are converted in accordance with the terms of this Indenture. Upon
surrender to the Paying Agent, such Securities shall be paid at the Redemption
Price stated in the notice.

     Section 10.05. Deposit of Redemption Price. Prior to 10:00 a.m., New York
City time on the Redemption Date, the Company shall deposit with the Paying
Agent (or if the Company or a Subsidiary or an Affiliate of either of them is
the Paying Agent, shall segregate and hold in trust) money sufficient to pay the
Redemption Price of all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which on or prior
thereto have been delivered by the Company to the Trustee for cancellation or
have been converted. The Paying Agent shall as promptly as practicable return to
the Company any money not required for that purpose because of conversion of
Securities pursuant to Article 11. If such money is then held by the Company in
trust and is not required for such purpose it shall be discharged from such
trust.

     Section 10.06. Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Security in an authorized
denomination equal in Original Principal Amount to the unredeemed portion of the
Security surrendered.

                                   Conversion

     Section 11.01. Right to Convert.

     (a)  Subject to and upon compliance with the provisions of this Indenture
the holder of any Security shall have the right, at such holder's option, to
convert the Original Principal Amount of the Security, or any portion of such
Original Principal Amount which is a multiple of $1,000, into fully paid and
nonassessable shares of Common Stock (as such shares shall then be constituted)
at the Conversion Rate in effect at such time, by surrender of the Security so
to be converted in whole or in part, together with any required funds, only
under the circumstances described in this Section 11.01 and in the manner
provided in Section 11.02.

     Notwithstanding any other provision of the Securities or this Indenture,
all Holders' rights with respect to conversion of the Securities and the
Company's obligation to deliver shares of Common Stock at the Conversion Rate
upon such conversion (the "Conversion Obligation"), are subject, in their
entirety, to the Company's right, in its sole and absolute discretion, to elect
to satisfy such Conversion Obligation in any manner permitted pursuant to
Section 11.03.

     (b)  Securities may be surrendered for conversion into shares of Common
Stock in integral multiples of $1,000 Original Principal Amount

          (i)    during any calendar quarter commencing prior to August 15, 2028
     (and only during such calendar quarter), if the Last Reported Sale Price of
     the Common Stock for at least 20 Trading Days in a period of 30 consecutive
     Trading Days ending on the last Trading Day of the previous calendar
     quarter is more than 130% of the Conversion Price as of the last day of
     such previous calendar quarter and

          (ii)   at any time after August 15, 2028 and prior to the Stated
     Maturity if, the Last Reported Sale Price of the Common Stock is greater
     than or equal to 130% of the Conversion Price on any day after August 15,
     2028.

     (c)  Securities may be surrendered for conversion into shares of Common
Stock in integral multiples of $1,000 Original Principal Amount at any time
during the five Business Day period after any five consecutive Trading Day
period in which the Trading Price of the Securities for each day of such five
Trading Day period was less than 98% of the product of the Last Reported Sale
Price and the Conversion Rate as of each such Trading Day.

                                       46

<PAGE>

Notwithstanding the foregoing, if, on the date of any conversion pursuant to
this Section 11.01(c), the Last Reported Sale Price of the Common Stock is
between 100% and 130% of the Conversion Price as of such date, the Holders of
Securities surrendered for conversion shall receive, in lieu of Common Stock
based on the Conversion Rate, cash or Common Stock or a combination of cash and
Common Stock, at the Company's option, with a value equal to the Accreted
Principal Amount of Securities plus accrued and unpaid interest, if any,
including Contingent Interest and Additional Interest, if any, as of the
Conversion Date ("Principal Value Conversion"). If a Holder surrenders its
Securities for a Principal Value Conversion, the Company shall notify such
Holder by the second Trading Day following the Conversion Date whether the
Company will pay such Holder all or a portion of the Accreted Principal Amount
plus accrued and unpaid Contingent Interest and Additional Interest, if any, in
cash, Common Stock or a combination of cash and Common Stock, and in what
percentage. Any Common Stock delivered upon a Principal Value Conversion will be
valued at the Applicable Stock Price. The Company will pay such Holder any
portion of the Accreted Principal Amount plus accrued and unpaid Contingent
Interest and Additional Interest, if any, to be paid in cash and deliver Common
Stock with respect to any portion of the Accreted Principal Amount plus accrued
and unpaid Contingent Interest and Additional Interest, if any, to be paid in
Common Stock, no later than the fifth Business Day following the determination
of the Applicable Stock Price.

In connection with any conversion pursuant to this Section 11.01(c), the Trustee
shall not have any obligation to determine the Trading Price of the Securities
unless the Company has requested such determination and the Company shall have
no obligation to make such request unless a Holder provides the Company with
reasonable evidence that the Trading Price is less than 98% of the product of
the Last Reported Sale Price of the Common Stock and the Conversion Rate. At
such time, the Company shall instruct the Trustee to determine the Trading Price
of the Securities beginning on the next Trading Day and on each successive
Trading Day until the Trading Price is greater than or equal to 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion
Rate as of such Trading Day.

     (d)  Any Securities called for redemption under Article 10 hereof may be
surrendered for conversion into shares of Common Stock in integral multiples of
$1,000 Original Principal Amount at any time prior to the close of business on
the Business Day immediately preceding the Redemption Date, even if the
Securities are not otherwise convertible at such time.

     (e)  Securities may be surrendered for conversion into shares of Common
Stock in integral multiples of $1,000 Original Principal Amount

          (i)  if the Company elects to distribute to all holders of Common
     Stock

                (A)  rights or warrants entitling them to purchase, for a period
          expiring within 60 days of the date of such distribution, Common Stock
          at less than the Last Reported Sale Price of the Common Stock on the
          Trading Day immediately preceding the declaration date for such
          distribution or

                (B)  assets, debt securities or rights to purchase the Company's
          securities, which distribution has a per share value as determined by
          the Board of Directors exceeding 5% of the Last Reported Sale Price of
          the Common Stock on the Trading Day immediately preceding the
          declaration date for such distribution

     beginning on the date that the Company gives notice to the Holders of such
     right, which shall not be less than 20 days prior to the time ("Ex-Dividend
     Time") immediately prior to the commencement of "ex-dividend" trading for
     such distribution on the New York Stock Exchange or such other principal
     national or regional exchange or market on which the Common Stock is then
     listed or quoted for such dividend or distribution, and Securities may be
     surrendered for conversion at any time thereafter until the earlier of the
     close of business on the Business Day prior to the Ex-Dividend Time and the
     date the Company announces that such dividend or distribution will not take
     place; provided that Holders shall not have the right to surrender
     Securities for conversion pursuant to this Section 11.01(e)(i) if they will
     otherwise participate in the distribution described above without first
     converting Securities into Common Stock; or

          (ii)   if the Company is a party to a consolidation, merger or binding
     share exchange pursuant to which shares of Common Stock would be converted
     into cash, securities or other property as set forth in Section 11.10(ii),
     at any time from and after the date that is 15 days prior to the
     anticipated effective date of the transaction until 15 days after the
     actual effective date of such transaction (or, if such transaction
     constitutes a Fundamental Change, until the applicable Fundamental Change
     Purchase Date) and, at the effective time of the transaction, the right to
     convert a Security into shares of Common Stock shall be changed into a
     right to convert such Security into the kind and amount of cash, securities
     or other property of the Company or another person that the Holder would
     have received if the Holder had converted such Security immediately prior
     to the transaction as set forth in Section 11.10.

                                       48

     (f)  Securities may be surrendered for conversion into shares of Common
Stock in integral multiples of $1,000 Original Principal Amount, during any
period in which (i) the credit rating assigned to the Securities by Standard &
Poor's Ratings Services, a division of The McGraw-Hill Companies Inc., and its
successors ("S&P") is below BB+, (ii) the credit rating assigned to the
Securities by Moody's Investors Services and its successors ("Moody's") is below
Ba1 or (iii) the Securities by are no longer rated by at least one of S&P or
Moody's.

     Section 11.02. Conversion Procedures. To convert a Security, a Holder must
(a) complete and manually sign the Notice of Conversion or a facsimile of the
Notice of Conversion on the back of the Security (the "Notice of Conversion")
and deliver such notice to the Conversion Agent, (b) surrender the Security to
the Conversion Agent, (c) furnish appropriate endorsements and transfer
documents if required by the Registrar or the Conversion Agent, (d) if required,
pay all transfer or similar taxes and (e) if required, pay funds equal to the
interest payable on the next Interest Payment Date. To convert a beneficial
interest in the Security, the holder thereof must comply with clauses (c)
through (e) of the preceding sentence and comply with the Depositary's
procedures for conversion. The date on which the Holder satisfies all of those
requirements is the "Conversion Date."

     Subject to the next succeeding sentence, the Company will, as soon as
practicable following the Conversion Settlement Date, (i) pay the cash component
(including cash in lieu of any fraction of a share to which such Holder would
otherwise be entitled), if any, of the Conversion Settlement Distribution
determined pursuant to Section 11.03 to the Holder of a Security surrendered for
conversion, or such Holder's nominee or nominees, and (ii) issue, or cause to be
issued, and deliver to the Conversion Agent or to such Holder, or such Holder's
nominee or nominees, certificates for the number of full shares of Common Stock,
if any, to which such Holder shall be entitled as part of such Conversion
Settlement Distribution. If a conversion is a Principal Value Conversion
pursuant to 11.01(c), the Company shall deliver to the Conversion Agent or to
the Holder, no later than the fifth Business Day following the date on which the
Applicable Stock Price is determined, a certificate for the number of whole
shares of Common Stock issuable upon the conversion and, if applicable, cash in
lieu of such Common Stock and cash in lieu of any fractional shares pursuant to
Section 11.04.

     The Person in whose name the Common Stock certificate is registered shall
be deemed to be a shareholder of record at the close of business on the
applicable Conversion Settlement Date; provided however, that if any such date
is a date when the stock transfer books of the Company are closed, such Person
shall be deemed a shareholder of record as of the next date on which the stock
transfer books of the Company are open.

                                       49

<PAGE>

     No payment or adjustment shall be made for dividends on, or other
distributions with respect to, any Common Stock except as provided in this
Article 11. On conversion of a Security, any accrued and unpaid interest
(including Contingent Interest, if any, Accreted Interest for all Interest
Periods concluding prior to the Conversion Date, if any, and Accreted Interest
for the Interest Period in which the Conversion Date occurs, if any) with
respect to such Security that is attributable to the period from the Issue Date
to the Conversion Date shall not be cancelled, extinguished or forfeited but
rather shall be deemed paid in full to the Holder of such Security through the
delivery of the Common Stock (together with the cash payment, if any, in lieu of
fractional shares), or cash or a combination of cash and Common Stock in lieu
thereof, in exchange for the Security being converted pursuant to the provisions
hereof, and the fair market value of the Common Stock (together with the cash
payment, if any, in lieu of fractional shares), or cash or a combination of cash
and Common Stock in lieu thereof, shall be treated as issued, to the extent
thereof, first in exchange for any accrued and unpaid interest (including
Contingent Interest, if any, Accreted Interest for all Interest Periods
concluding prior to the Conversion Date, if any, and Accreted Interest for the
Interest Period in which the Conversion Date occurs, if any) attributable to the
period from the Issue Date to the Conversion Date, and the balance, if any, of
such fair market value shall be treated as issued in exchange for the Original
Principal Amount of the Security being converted pursuant to the provisions
hereof. Notwithstanding the preceding sentence, on conversion of a Security
during the period from the close of business on any Regular Record Date
immediately preceding any Interest Payment Date to the close of business on the
Business Day immediately preceding such Interest Payment Date, the Holder on
such Regular Record Date shall receive the interest payable on such Interest
Payment Date.

     The Company agrees, and by acceptance of a beneficial interest in a
Security each Holder and any beneficial owner of a Security shall be deemed to
agree, to be bound (in the absence of an administrative determination or
judicial ruling to the contrary) by the Company's determination of the projected
payment schedule within the meaning of the contingent debt regulations, and
accordingly shall treat, for United States federal income tax purposes, the fair
market value of the Common Stock received upon the conversion of a Security
(together with any cash payment in lieu of fractional shares) or cash in lieu
thereof, or a combination of cash and Common Stock as a contingent payment on
the Security for purposes of Treasury Regulation Section 1.1275-4 or any
successor provision.

     If a Holder converts more than one Security at the same time, the number of
shares of Common Stock issuable upon the conversion shall be based on the
aggregate Original Principal Amount of Securities converted.

                                       50

<PAGE>

     Upon surrender of a Security that is converted in part, the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder, a new
Security equal in Original Principal Amount to the Original Principal Amount of
the unconverted portion of the Security surrendered.

     Securities or portions thereof surrendered for conversion during the period
from the close of business on any Regular Record Date immediately preceding any
Interest Payment Date to the close of business on the Business Day immediately
preceding such Interest Payment Date shall be accompanied by payment to the
Company or its order, in New York Clearing House funds or other funds acceptable
to the Company, of an amount equal to the interest payable on such Interest
Payment Date with respect to the Original Principal Amount of Securities or
portions thereof being surrendered for conversion; provided that no such payment
need be made if (1) the Company has specified a Redemption Date that occurs
during the period from the close of business on a Regular Record Date to the
close of business on the Interest Payment Date to which such Regular Record Date
relates, (2) the Company has specified a Fundamental Change Purchase Date during
such period or (3) only to the extent of overdue interest or overdue Contingent
Interest, any overdue interest or overdue Contingent Interest exists on the
Conversion Date with respect to the Securities converted.

     Section 11.03. Payment of Cash in Lieu of Common Stock.

     (a)  If a Holder elects to convert all or any portion of a Security into
shares of Common Stock as set forth in Section 11.01 and the Company receives
such Holder's Notice of Conversion on or prior to the day that is 20 days prior
to the Stated Maturity, or with respect to Securities called for redemption
pursuant to Section 10.01, the applicable Redemption Date (the "Final Notice
Date"), the Company may choose to satisfy all or any portion of the Conversion
Obligation in cash. Upon such election, the Company will notify such Holder
through the Trustee of the dollar amount to be satisfied in cash (which must be
expressed either as 100% of the Conversion Obligation or as a fixed dollar
amount) at any time on or before the date that is two Business Days following
the Company's receipt of the Notice of Conversion (such period, the "Cash
Settlement Notice Period"). If the Company elects to pay cash for any portion of
the shares otherwise issuable to the Holder, the Holder may retract the Notice
of Conversion at any time during the two Business Day period beginning on the
day after the final day of the Cash Settlement Notice Period (the "Conversion
Retraction Period"); no such retraction can be made (and a Notice of Conversion
shall be irrevocable) if the Company does not elect to deliver cash in lieu of
shares of Common Stock (other than cash in lieu of fractional shares). With
respect to any Notice of Conversion received by the Company prior to the Final
Notice Date, the "Conversion Settlement Distribution" for any Security

                                       51

<PAGE>

subject to such Notice of Conversion shall consist of cash, Common Stock or a
combination thereof, as selected by the Company as set forth below:

          (i)    if the Company elects to satisfy the entire Conversion
     Obligation in shares of Common Stock, the Conversion Settlement
     Distribution shall be a number of shares equal to (1) the aggregate
     Original Principal Amount of the Securities to be converted divided by
     1,000, multiplied by (2) the Conversion Rate, plus cash for any fractional
     shares pursuant to Section 11.04;

          (ii)   if the Company elects to satisfy the entire Conversion
     Obligation in cash, the Conversion Settlement Distribution shall be cash in
     an amount equal to the product of:

                  (A)  a number equal to the product of (x) the aggregate
          Original Principal Amount of Securities to be converted divided by
          1,000 multiplied by (y) the Conversion Rate, and

                  (B)  the average of the Last Reported Sale Prices of the
          Common Stock for the 10 Trading Days beginning on the Trading Day
          immediately following the final day of the Conversion Retraction
          Period (the "Cash Settlement Averaging Period"); and

          (iii)  if the Company elects to satisfy a fixed portion (other than
     100%) of the Conversion Obligation in cash, the Conversion Settlement
     Distribution shall consist of such cash amount ("Cash Amount") and a number
     of shares equal to the greater of (1) zero and (2) the excess, if any, of
     the number of shares calculated as set forth in clause (i) above over the
     number of shares equal to the sum, for each day of the Cash Settlement
     Averaging Period, of (x) 10% of the Cash Amount, divided by (y) the Last
     Reported Sale Price of the Common Stock on such day, plus cash for any
     fractional shares pursuant to Section 11.04.

     (b)  At any time on or before any Final Notice Date, the Company will
notify the Trustee whether it intends to satisfy all or any portion of the
Conversion Obligation with respect to conversions of Securities for which the
Company receives a Notice of Conversion after such Final Notice Date and the
dollar amount to be satisfied in cash (which must be expressed either as 100% or
as a fixed dollar amount). In such case, the applicable Conversion Settlement
Distribution will be computed in the same manner as set forth in clause (a)
above except that the Cash Settlement Averaging Period shall be the 10 Trading
Days beginning on the first Trading Day following the Company's receipt of the
Notice of Conversion or in the event that the Company receives a Notice of

                                       52

<PAGE>

Conversion on the Business Day prior to the Stated Maturity, the 10 Trading Days
beginning on the first Trading Day after the Stated Maturity.

     Section 11.04. Fractional Shares. The Company shall not issue a fractional
share of Common Stock upon conversion of a Security. Instead, the Company will
deliver cash for the current market value of the fractional share. The current
market value of a fractional share of Common Stock shall be determined, to the
nearest 1/1,000th of a share, by multiplying the Last Reported Sale Price of a
full share of Common Stock on the Trading Day immediately preceding the
Conversion Settlement Date by the fractional amount and rounding the product to
the nearest whole cent.

     Section 11.05. Taxes on Conversion. If a Holder converts a Security, the
Company shall pay any documentary, stamp or similar issue or transfer taxes due
on the issue of shares of Common Stock upon such conversion. However, the Holder
shall pay any such tax which is due because the Holder requests the shares to be
issued in a name other than the Holder's name. The Conversion Agent may refuse
to deliver the certificate representing the Common Stock being issued in a name
other than the Holder's name until the Conversion Agent receives a sum
sufficient to pay any tax which will be due because the shares are to be issued
in a name other than the Holder's name. Nothing herein shall preclude any tax
withholding required by law or regulation.

     Section 11.06. Reservation of Shares, Shares to Be Fully Paid; Compliance
with Governmental Requirements; Listing of Common Stock.

     (a)  The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock to provide for the conversion of the Securities from time to time
as such Securities are presented for conversion.

     (b)  Before taking any action which would cause an adjustment increasing
the Conversion Rate to an amount that would cause the Conversion Price to be
reduced below the then par value, if any, of the shares of Common Stock issuable
upon conversion of the Securities, the Company will take all corporate action,
if any, which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Rate.

     (c)  (i) The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be fully paid and
nonassessable by the Company and, subject to the provisions of Section 11.05,
free from all taxes, liens and charges with respect to the issue thereof.

                                       53

<PAGE>

          (ii)   The Company covenants that, if any shares of Common Stock to be
     provided for the purpose of conversion of Securities hereunder require
     registration with or approval of any governmental authority under any
     federal or state law before such shares may be validly issued upon
     conversion, the Company will in good faith and as expeditiously as
     possible, to the extent then permitted by the rules and interpretations of
     the Securities and Exchange Commission (or any successor thereto), endeavor
     to secure such registration or approval, as the case may be.

     (d)  The Company further covenants that, if at any time the Common Stock
shall be listed on the NYSE or any other national securities exchange or
automated quotation system, the Company will, if permitted by the rules of such
exchange or automated quotation system, list and keep listed, so long as the
Common Stock shall be so listed on such exchange or automated quotation system,
all Common Stock issuable upon conversion of the Security; provided, however,
that, if the rules of such exchange or automated quotation system permit the
Company to defer the listing of such Common Stock until the first conversion of
the Securities into Common Stock in accordance with the provisions of this
Indenture, the Company covenants to list such Common Stock issuable upon
conversion of the Securities in accordance with the requirements of such
exchange or automated quotation system at such time.

     Section 11.07. Adjustment of Conversion Rate. The Conversion Rate shall be
adjusted from time to time by the Company as follows:

     (a)  In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect at the opening of
business on the date following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution by a
fraction,

         (i)     the numerator of which shall be the sum of the number of shares
     of Common Stock outstanding at the close of business on the date fixed for
     the determination of stockholders entitled to receive such dividend or
     other distribution plus the total number of shares of Common Stock
     constituting such dividend or other distribution; and

         (ii)    the denominator of which shall be the number of shares of
     Common Stock outstanding at the close of business on the date fixed for
     such determination,

such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If any dividend or

                                       54

<PAGE>

distribution of the type described in this Section 11.07(a) is declared but not
so paid or made, the Conversion Rate shall again be adjusted to the Conversion
Rate that would then be in effect if such dividend or distribution had not been
declared.

     (b)  In case the Company shall issue rights or warrants to all holders of
its outstanding shares of Common Stock entitling them (for a period expiring
within sixty (60) days after the date fixed for determination of stockholders
entitled to receive such rights or warrants) to subscribe for or purchase shares
of Common Stock at a price per share less than the Current Market Price as of
the date immediately preceding the record date fixed for determination of
stockholders entitled to receive such rights or warrants, the Conversion Rate
shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the date fixed
for determination of stockholders entitled to receive such rights or warrants by
a fraction,

               (i)  the numerator of which shall be the number of shares of
     Common Stock outstanding on the record date fixed for determination of
     stockholders entitled to receive such rights or warrants plus the total
     number of additional shares of Common Stock offered for subscription or
     purchase, and

               (ii) the denominator of which shall be the sum of the number of
     shares of Common Stock outstanding at the close of business on the record
     date fixed for determination of stockholders entitled to receive such
     rights or warrants plus the number of shares that the aggregate offering
     price of the total number of shares so offered would purchase at a price
     equal to the Current Market Price as of the date immediately preceding the
     record date fixed for determination of stockholders entitled to receive
     such rights or warrants.

     Such adjustment shall be successively made whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of
business on the day following the date fixed for determination of stockholders
entitled to receive such rights or warrants. To the extent that shares of Common
Stock are not delivered after the expiration of such rights or warrants, the
Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect had the adjustments made upon the issuance of such rights or warrants
been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. If such rights or warrants are not so issued, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such date fixed for the determination of stockholders entitled to
receive such rights or warrants had not been fixed. In determining whether any
rights or warrants entitle the holders to subscribe for or purchase shares of

                                       55

<PAGE>

Common Stock at a price less than the Current Market Price as of the date
immediately preceding the record date fixed for determination of stockholders
entitled to receive such rights or warrants, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account
any consideration received by the Company for such rights or warrants and any
amount payable on exercise or conversion thereof, the value of such
consideration, if other than cash, to be determined by the Board of Directors.

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

     (d)  In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock assets, debt securities, shares of any class of
capital stock of the Company or rights or warrants to purchase any securities of
the Company excluding (x) any dividend or distribution or issuance referred to
in Section 11.07(a), (b) or (g) and (y) any dividend or distribution paid
exclusively in cash (any of the foregoing hereinafter in this Section 11.07(d)
called the "Distributed Assets or Securities")), then, in each such case, the
Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect on the Record Date with
respect to such distribution by a fraction,

             (i)    the numerator of which shall be the Current Market Price on
     such Record Date; and

             (ii)   the denominator of which shall be the Current Market Price
     on such Record Date less the Fair Market Value (as determined by the Board
     of Directors, whose determination shall be conclusive, and described in a
     resolution of the Board of Directors) on the Record Date of the portion of
     the Distributed Assets or Securities so distributed applicable to one share
     of Common Stock,

such adjustment to become effective immediately prior to the opening of business
on the day following such Record Date; provided that if the difference between
the Current Market Price on the Record Date and the then Fair Market Value (as
so determined) of the portion of the Distributed Securities so

                                       56

<PAGE>

distributed applicable to one share of Common Stock is less than $1.00, in lieu
of the foregoing adjustment, adequate provision shall be made so that each
Holder shall have the right to receive upon conversion the amount of Distributed
Assets or Securities such holder would have received had such holder converted
each Security on the Record Date. If such dividend or distribution is not so
paid or made, the Conversion Rate shall again be adjusted to be the Conversion
Rate that would then be in effect if such dividend or distribution had not been
declared. If the Board of Directors determines the Fair Market Value of any
distribution for purposes of this Section 11.07(d) by reference to the actual or
when issued trading market for any securities, it must in doing so consider the
prices in such market over the same period used in computing the Current Market
Price on the applicable Record Date.

     Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 11.07 (and no adjustment to the Conversion Rate under
this Section 11.07 will be required) until the occurrence of the earliest
Trigger Event, whereupon such rights and warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 11.07(d). If any such right or warrant,
including any such existing rights or warrants distributed prior to the date of
this Indenture, are subject to events, upon the occurrence of which such rights
or warrants become exercisable to purchase different securities, evidences of
indebtedness or other assets, then the date of the occurrence of any and each
such event shall be deemed to be the date of distribution and record date with
respect to new rights or warrants with such rights (and a termination or
expiration of the existing rights or warrants without exercise by any of the
holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 11.07 was made, (1) in the case of any such
rights or warrants that shall all have been redeemed or repurchased without
exercise by any holders thereof, the Conversion Rate shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or
Trigger Event, as the case may be, as though it were a cash distribution, equal
to the per share redemption or repurchase price received by a holder or holders
of Common Stock with respect to such rights or warrants (assuming such holder
had retained such rights or warrants), made to all holders of Common Stock as of
the date of such

                                       57

<PAGE>

redemption or repurchase, and (2) in the case of such rights or warrants that
shall have expired or been terminated without exercise thereof, the Conversion
Rate shall be readjusted as if such expired or terminated rights and warrants
had not been issued.

     For purposes of this Section 11.07(d) and Section 11.07(a) and (b), any
dividend or distribution to which this Section 11.07(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock described in Section 11.07(b) (or both), shall
be deemed instead to be (1) a dividend or distribution of the evidences of
assets, debt securities or shares of capital stock other than such shares of
Common Stock or rights or warrants (and any Conversion Rate adjustment required
by this Section 11.07(d) with respect to such dividend or distribution shall
then be made) immediately followed by (2) a dividend or distribution of such
shares of Common Stock or such rights or warrants (and any further Conversion
Rate adjustment required by Sections 11.07(a) and 11.07(b) with respect to such
dividend or distribution shall then be made), except (A) the Record Date of such
dividend or distribution shall be substituted as "the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution", "the date fixed for the determination of stockholders entitled to
receive such rights or warrants" and "the date fixed for such determination"
within the meaning of Section 11.07(a) and 11.07(b) and (B) any shares of Common
Stock included in such dividend or distribution shall not be deemed "outstanding
at the close of business on the date fixed for such determination" within the
meaning of Section 11.07(a).

     (e)  In case the Company shall, by dividend or otherwise, make
distributions consisting exclusively of cash to all holders of its Common Stock,
excluding any quarterly cash dividend on the Common Stock to the extent that the
aggregate cash dividend per share of Common Stock in any quarter does not exceed
$0.12 (the "Dividend Threshold Amount") then, in such case, the Conversion Rate
shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the close of
business on such record date by a fraction,

             (i)    the numerator of which shall be the Current Market Price on
     such record date; and

             (ii)   the denominator of which shall be the Current Market Price
     on such record date less the amount of cash so distributed applicable to
     one share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on
the day following the record date; provided that if the portion of the cash so
distributed applicable to one share of Common Stock is equal to or greater than

                                       58

<PAGE>

the Current Market Price on the record date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each Holder shall have the
right to receive upon conversion the amount of cash such holder would have
received had such holder converted each Security on the Record Date. If such
dividend or distribution is not so paid or made, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared. If any adjustment is required to
be made as set forth in this Section 11.07(e) as a result of a distribution that
is a quarterly dividend, such adjustment shall be based upon the amount by which
such distribution exceeds the Dividend Threshold Amount. If an adjustment is
required to be made as set forth in this Section 11.07(e) above as a result of a
distribution that is not a quarterly dividend, such adjustment shall be based
upon the full amount of the distribution.

     (f)  In case a tender or exchange offer made by the Company or any
Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors)
that as of the last time (the "Expiration Time") tenders or exchanges may be
made pursuant to such tender or exchange offer (as it may be amended) exceeds
the Last Reported Sale Price of a share of Common Stock on the Trading Day next
succeeding the Expiration Time, the Conversion Rate shall be increased so that
the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the Expiration Time by a fraction,

            (i)     the numerator of which shall be the sum of (x) the Fair
     Market Value (determined as aforesaid) of the aggregate consideration
     payable to stockholders based on the acceptance (up to any maximum
     specified in the terms of the tender or exchange offer) of all shares
     validly tendered or exchanged and not withdrawn as of the Expiration Time
     (the shares deemed so accepted up to any such maximum, being referred to as
     the "Purchased Shares") and (y) the product of the number of shares of
     Common Stock outstanding (less any Purchased Shares) at the Expiration Time
     and the Last Reported Sale Price of a share of Common Stock on the Trading
     Day next succeeding the Expiration Time, and

            (ii)    the denominator of which shall be the number of shares of
     Common Stock outstanding (including any tendered or exchanged shares) at
     the Expiration Time multiplied by the Last Reported Sale Price of a share
     of Common Stock on the Trading Day next succeeding the Expiration Time,

                                       59

<PAGE>

such adjustment to become effective immediately prior to the opening of business
on the day following the Expiration Time. If the Company is obligated to
purchase shares pursuant to any such tender or exchange offer, but the Company
is permanently prevented by applicable law from effecting any such purchases or
all such purchases are rescinded, the Conversion Rate shall again be adjusted to
be the Conversion Rate that would then be in effect if such tender or exchange
offer had not been made.

     (g)  If the Company pays a dividend or makes a distribution to all holders
of its Common Stock consisting of capital stock of any class or series, or
similar equity interests, of or relating to a Subsidiary or other business unit
of the Company, the Conversion Rate shall be increased so that the same shall be
equal to the rate determined by multiplying the Conversion Rate in effect on the
Record Date with respect to such distribution by a fraction,

              (i)   the numerator of which shall be the sum of (A) the average
     of the Last Reported Sale Prices of the Common Stock for the ten (10)
     Trading Days commencing on and including the fifth Trading Day after the
     date on which "ex-dividend trading" commences for such dividend or
     distribution on The New York Stock Exchange or such other national or
     regional exchange or market which such securities are then listed or quoted
     (the "Ex-Dividend Date") plus (B) the fair market value of the securities
     distributed in respect of each share of Common Stock for which this Section
     11.07(g) applies and shall equal the number of securities distributed in
     respect of each share of Common Stock multiplied by the average of the
     closing sale prices of those securities distributed for the ten (10)
     Trading Days commencing on and including the fifth Trading Day after the
     Ex-Dividend Date; and

              (ii)  the denominator of which shall be the average of the Last
     Reported Sale Prices of the Common Stock for the ten (10) Trading Days
     commencing on and including the fifth Trading Day after the Ex-Dividend
     Date,

such adjustment to become effective immediately prior to the opening of business
on the day following fifteenth Trading Day after the Ex-Dividend Date; provided
that if (x) the average of the Last Reported Sale Prices of the Common Stock for
the ten (10) Trading Days commencing on and including the fifth Trading Day
after the Ex-Dividend Date minus (y) the fair market value of the securities
distributed in respect of each share of Common Stock for which this Section
11.07(g) applies (as calculated in Section 11.07(g)(i)(B) above) is less than
$1.00, then the adjustment provided by for by this Section 11.07(g) shall not be
made and in lieu thereof the provisions of Section 11.10 shall apply to such
distribution.

                                       60

<PAGE>

     (h)  Notwithstanding anything to the contrary, in the event of an
adjustment to the Conversion Rate pursuant to Section 11.07 (e) or (f), in no
event with the Conversion Rate exceed 20.1207 (the "Maximum Conversion Rate").
The Maximum Conversion Rate is subject to the same proportional adjustments made
to the Conversion Rate pursuant to Section 11.07(a), (b), (c), (d) or (g).

     (i)  If any adjustment or readjustment is made to the Conversion Rate
pursuant to this Section 11.07 (other than pursuant to Section 11.07 (e)), the
same proportional adjustment shall be made to the Dividend Threshold Amount;
provided that the Dividend Threshold Amount shall be decreased whenever the
Conversion Rate is increased and increased whenever the Conversion Rate is
decreased.

     (j)  For purposes of this Section 11.07, the following terms shall have the
meaning indicated:

           (i)  "Current Market Price" shall mean the average of the daily Last
     Reported Sale Prices per share of Common Stock for the twenty consecutive
     Trading Days ending on the earlier of such date of determination and the
     day before the "ex" date with respect to the issuance, distribution,
     subdivision or combination requiring such computation immediately prior to
     the date in question. For purpose of this paragraph, the term "ex" date,
     (1) when used with respect to any issuance or distribution, means the first
     date on which the Common Stock trades, regular way, on the relevant
     exchange or in the relevant market from which the Last Reported Sale Price
     was obtained without the right to receive such issuance or distribution,
     and (2) when used with respect to any subdivision or combination of shares
     of Common Stock, means the first date on which the Common Stock trades,
     regular way, on such exchange or in such market after the time at which
     such subdivision or combination becomes effective.

     If another issuance, distribution, subdivision or combination to which
     Section 11.07 applies occurs during the period applicable for calculating
     "Current Market Price" pursuant to the definition in the preceding
     paragraph, "Current Market Price" shall be calculated for such period in a
     manner determined by the Board of Directors to reflect the impact of such
     issuance, distribution, subdivision or combination on the Last Reported
     Sale Price of the Common Stock during such period.

           (ii)  "Fair Market Value" shall mean the amount which a willing buyer
     would pay a willing seller in an arm's-length transaction.

                                       61

<PAGE>

           (iii)  "Record Date" shall mean, with respect to any dividend,
     distribution or other transaction or event in which the holders of Common
     Stock have the right to receive any cash, securities or other property or
     in which the Common Stock (or other applicable security) is exchanged for
     or converted into any combination of cash, securities or other property,
     the date fixed for determination of stockholders entitled to receive such
     cash, securities or other property (whether such date is fixed by the Board
     of Directors or by statute, contract or otherwise).

     (k)  The Company may make such increases in the Conversion Rate in addition
to those required by Section 11.07(a), (b), (c), (d), (e), (f) or (g) as the
Board of Directors considers to be advisable to avoid or diminish any income tax
to holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes.

     To the extent permitted by applicable law, the Company from time to time
may increase the Conversion Rate by any amount for any period of time if the
period is at least twenty (20) Business Days, the increase is irrevocable during
the period and the Board of Directors shall have made a determination that such
increase would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to Holders a notice of the increase
at least fifteen (15) days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period
during which it will be in effect.

     (l)  No adjustment in the Conversion Rate shall be required unless such
adjustment would require an increase or decrease of at least one percent (1%) in
such rate; provided that any adjustments that by reason of this Section 11.07(l)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Article 11 shall be made
by the Company and shall be made to the nearest cent or to the nearest one-ten
thousandth (1/10,000) of a share, as the case may be. To the extent the
Securities become convertible into cash, assets or property, subject to Section
11.10, no adjustment need be made thereafter as to the cash, assets or property.
Interest will not accrue on any cash into which the Securities are convertible.

     (m)  Whenever the Conversion Rate is adjusted as herein provided, the
Company shall promptly file with the Trustee and any Conversion Agent other than
the Trustee an Officers' Certificate setting forth the Conversion Rate after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a Responsible Officer of the Trustee or Conversion
Agent shall have received such Officers' Certificate, the Trustee or Conversion
Agent, as the case may be, shall not be deemed to have knowledge of any

                                       62

<PAGE>

adjustment of the Conversion Rate and may assume that the last Conversion Rate
of which it has knowledge is still in effect. Promptly after delivery of such
certificate, the Company shall prepare a notice of such adjustment of the
Conversion Rate setting forth the adjusted Conversion Rate and the date on which
each adjustment becomes effective and shall mail such notice of such adjustment
of the Conversion Rate to the Holder of each Security at his last address
appearing on the Security Register within twenty (20) days after execution
thereof. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

     (n)  In any case in which this Section 11.07 provides that an adjustment
shall become effective immediately after (1) a record date or Record Date for an
event, (2) the date fixed for the determination of stockholders entitled to
receive a dividend or distribution pursuant to Section 11.07(a), (3) a date
fixed for the determination of stockholders entitled to receive rights or
warrants pursuant to Section 11.07(b), or (4) the Expiration Time for any tender
or exchange offer pursuant to Section 11.07(f) (each a "Determination Date"),
the Company may elect to defer until the occurrence of the applicable Adjustment
Event (as hereinafter defined) (x) issuing to the holder of any Security
converted after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock or other securities
issuable upon such conversion, or cash in lieu thereof, by reason of the
adjustment required by such Adjustment Event over and above the Common Stock
issuable upon such conversion, or cash in lieu thereof, before giving effect to
such adjustment and (y) paying to such holder any amount in cash in lieu of any
fraction pursuant to Section 11.04. For purposes of this Section 11.07(n), the
term "Adjustment Event" shall mean:

            (i)   in any case referred to in clause (1) hereof, the occurrence
     of such event,

            (ii)  in any case referred to in clause (2) hereof, the date any
     such dividend or distribution is paid or made,

            (iii) in any case referred to in clause (3) hereof, the date of
     expiration of such rights or warrants, and

            (iv)  in any case referred to in clause (4) hereof, the date a sale
     or exchange of Common Stock pursuant to such tender or exchange offer is
     consummated and becomes irrevocable.

     (o)  For purposes of this Section 11.07, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company, unless such treasury shares participate in any distribution or
dividend that requires an adjustment pursuant to this Section

                                       63

<PAGE>

11.07, but shall include shares issuable in respect of scrip certificates issued
in lieu of fractions of shares of Common Stock.

     Section 11.08. When No Adjustment Required. When No Adjustment Required. No
adjustment to the Conversion Rate need be made:

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

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

     (c)  upon the issuance of any shares of Common Stock pursuant to any
option, warrant, right, or exercisable, exchangeable or convertible security not
described in paragraph (b) above and outstanding as of the date of this
Indenture;

     (d)  for a change in the par value or no par value of the Common Stock; or

     (e)  for accrued and unpaid interest (including Contingent Interest or
Additional Interest, if any).

     Section 11.09. Notice of Certain Transactions. In the event that:

            (i)   the Company takes any action which would require an adjustment
     in the Conversion Rate;

            (ii)  the Company takes any action that requires a supplemental
     indenture pursuant to Section 11.10; or

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

the Company shall mail to Holders and file with the Trustee a notice stating the
proposed record or effective date, as the case may be. The Company shall mail
the notice at least fifteen days before such date. Failure to mail such notice
or any defect therein shall not affect the validity of any transaction referred
to in clause (i), (ii) or (iii) of this Section 11.09.

     Section 11.10. Effect of Reclassification, Consolidation, Merger or Sale on
Conversion Privilege. If any of the following events occur, namely (i) any
reclassification or change of the outstanding shares of Common Stock (other than
a subdivision or combination to which Section 11.07(c) applies), (ii) any

                                       64

<PAGE>

consolidation, merger, binding share exchange or combination of the Company with
another Person as a result of which holders of Common Stock shall be entitled to
receive stock, other securities or other property or assets (including cash)
with respect to or in exchange for such Common Stock, or (iii) any sale or
transfer of all or substantially all of the properties and assets of the Company
to any other Person as a result of which holders of Common Stock shall be
entitled to receive stock, other securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, then the
Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental
indenture) providing that each Security shall be convertible into the kind and
amount of shares of stock, other securities or other property or assets
(including cash) receivable upon such reclassification, change, consolidation,
merger, binding share exchange, combination, sale or transfer by a holder of a
number of shares of Common Stock issuable upon conversion of such Securities
(assuming, for such purposes, a sufficient number of authorized shares of Common
Stock are available to convert all such Securities) immediately prior to such
reclassification, change, consolidation, merger, combination, binding share
exchange, sale or transfer assuming such holder of Common Stock did not exercise
his rights of election, if any, as to the kind or amount of stock, other
securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, binding share exchange,
combination, sale or transfer (provided that, if the kind or amount of stock,
other securities or other property or assets (including cash) receivable upon
such reclassification, change, consolidation, merger, combination, sale or
transfer is not the same for each share of Common Stock in respect of which such
rights of election shall not have been exercised ("non-electing share"), then
for the purposes of this Section 11.10 the kind and amount of stock, other
securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, binding share exchange,
combination, sale or transfer for each non-electing share shall be deemed to be
the kind and amount so receivable per share by a plurality of the non-electing
shares). Such supplemental indenture shall provide for adjustments which shall
be as nearly equivalent as may be practicable to the adjustments provided for in
this Article 11.

     The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder of Securities, at its address appearing on
the Security register, within twenty (20) days after execution thereof and shall
issue a press release containing such information and publish such information
on its website on the World Wide Web. Failure to deliver such notice shall not
affect the legality or validity of such supplemental indenture.

                                       65

<PAGE>

     The above provisions of this Section 11.10 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, binding share
exchanges, combinations, sales and transfers.

     If this Section 11.10 applies to any event or occurrence, Section 11.07
shall not apply.

     Section 11.11. Trustee's Disclaimer. The Trustee shall have no duty to
determine when an adjustment under this Article 11 should be made, how it should
be made or what such adjustment should be, but may accept as conclusive evidence
of that fact or the correctness of any such adjustment, and shall be protected
in relying upon, an Officers' Certificate including the Officers' Certificate
with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 11.07(m). 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 Company's failure
to comply with any provisions of this Article 11.

     The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 11.10, but may accept as conclusive evidence of the
correctness thereof, and shall be fully protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 11.07(m).

     Section 11.12. Rights Issued in Respect of Common Stock Issued Upon
Conversion. Each share of Common Stock issued upon conversion of Securities
pursuant to this Article 11 shall be entitled to receive the appropriate number
of common stock or preferred stock purchase rights, as the case may be (the
"Rights"), if any, that shares of Common Stock are entitled to receive and the
certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
shareholder rights agreement adopted by the Company, as the same may be amended
from time to time (in each case, a "Rights Agreement"). Provided that such
Rights Agreement requires that each share of Common Stock issued upon conversion
of Securities at any time prior to the distribution of separate certificates
representing the Rights be entitled to receive such Rights, then,
notwithstanding anything else to the contrary in this Article 11, there shall
not be any adjustment to the conversion privilege or Conversion Rate as a result
of the issuance of Rights, but an adjustment to the Conversion Rate shall be
made pursuant to Section 11.07(d) upon the separation of the Rights from the
Common Stock.

                                       66

     Section 11.13. Company Determination Final. Any determination that the
Company or the Board of Directors must make pursuant to Sections 11.02, 11.04,
11.07 or 11.10 shall be conclusive.

                                   ARTICLE 12
                          Purchase At Option of Holders

     Section 12.01. Right to Require Purchase.

     (a)  Each Holder has the right to require the Company to purchase all or a
portion of the Securities held by such Holder on August 15, 2008, 2013, 2018,
2023, and 2028, or if any such day is not a Business Day, on the immediately
succeeding Business Day (each, a "Purchase Date").

     (b)  On or before the 20/th/ Business Day prior to each Purchase Date, the
Company shall mail a written notice to the Trustee and any Paying Agent and to
each Holder at its address shown in the Security Register.

     The notice shall include the form of Purchase Notice to be completed by the
Holder and shall state:

            (i)  the Purchase Price;

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

          (iii)  the Conversion Rate and any adjustments to the Conversion
     Rate;

           (iv)  that the Securities with respect to which a Purchase Notice has
     been given by the Holder may be converted only if the Holder withdraws the
     Purchase Notice in accordance with the terms of the Indenture; and

            (v)  the procedures set forth in Section 12.02 that each Holder must
     follow to exercise its right to require the Company to purchase such
     Holder's Securities.

     In connection with providing such notice, the Company shall issue a press
release containing the information included in the notice and publish such
information on its website on the World Wide Web.

     Section 12.02. Purchase Procedures. The Company shall purchase such
Securities for cash at a Purchase Price equal to 100% of the Accreted Principal
Amount thereof, plus accrued and unpaid interest (including Contingent Interest

                                       67

<PAGE>

and Additional Interest, if any) to, but excluding, the Purchase Date (the
"Purchase Price") (provided that if the Purchase Date is an Interest Payment
Date, any accrued and unpaid interest, Contingent Interest or Additional
Interest, shall be paid to the Holder of record as of the applicable Regular
Record Date, rather than to the Holder presenting the Security for purchase), at
the option of the Holder thereof, upon:

     (a)  delivery to the Paying Agent by the Holder of a written notice of
purchase (a "Purchase Notice") at any time from the opening of business on the
date that is 20 Business Days prior to a Purchase Date until the close of
business on the Business Day immediately preceding such Purchase Date stating:

             (i)  if a certificated Security has been issued, the certificate
     number of the Security which the Holder will deliver to be purchased or if
     not, such information as may be required under applicable procedures of the
     Depositary,

            (ii)  the portion of the Original Principal Amount of the Security
     which the Holder will deliver to be purchased, which portion must be $1,000
     or an integral multiple thereof, and

           (iii)  that such Security shall be purchased as of the applicable
     Purchase Date pursuant to the provisions of the Securities and this Article
     12; and

     (b)  delivery of such Security to the Paying Agent prior to, on or after
the Purchase Date (together with all necessary endorsements) at the offices of
the Paying Agent, such delivery being a condition to receipt by the Holder of
the Purchase Price therefor; provided, however, that such Purchase Price shall
be so paid pursuant to this Article 12 only if the Security so delivered to the
Paying Agent shall conform in all respects to the description thereof in the
related Purchase Notice.

     The Company shall purchase from the Holder thereof, pursuant to this
Article 12, a portion of a Security if the Original Principal Amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

     Any purchase by the Company contemplated pursuant to the provisions of this
Article 12 shall be consummated by the payment of the Purchase Price to be
received by the Holder in cash promptly following the later of the Purchase Date
and the time of delivery of the Security as set forth in Section 12.04.

                                       68

<PAGE>

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Purchase Notice contemplated by this Section 12.02 shall
have the right to withdraw such Purchase Notice at any time prior to the close
of business on the Business Day immediately preceding the Purchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 12.03.

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

     The Company may, at its option, specify additional dates on which Holders
will have the right to require it to purchase Securities upon written notice to
the Paying Agent, the Trustee and the Holders. Such notice shall specify the
additional dates upon which the Company shall be required to purchase the
Securities at the option of the Holders and shall be delivered to the Paying
Agent, the Trustee and the Holders no less than 25 Business Days prior to the
earliest purchase date specified in such notice.

     Section 12.03. Effect of Purchase Notice. Upon receipt by the Paying Agent
of the Purchase Notice specified in Section 12.02(a), the Holder of the Security
in respect of which such Purchase Notice was given shall (unless such Purchase
Notice is withdrawn as specified in the following two paragraphs) thereafter be
entitled to receive solely the Purchase Price with respect to such Security.
Such Purchase Price shall be paid to such Holder, subject to receipt of funds by
the Paying Agent, promptly following the later of (x) the Purchase Date with
respect to such Security (provided the conditions in Section 12.02 have been
satisfied) and (y) the time of delivery of such Security to the Paying Agent by
the Holder thereof in the manner required by Section 12.02. Securities in
respect of which a Purchase Notice has been given by the Holder thereof may not
be converted pursuant to Article 11 hereof on or after the date of the delivery
of such Purchase Notice unless such Purchase Notice has first been validly
withdrawn as specified in the following two paragraphs.

     A Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent at any time prior to the
close of business on the applicable Purchase Date specifying:

            (i)   if certificated Securities have been issued, the certificate
     number of the Security in respect of which such notice of withdrawal is
     being submitted, or if not, such information as may be required under
     appropriate procedures of the Depositary;

           (ii)   the Original Principal Amount of the Security with respect to
     which such notice of withdrawal is being submitted; and

            (iii)  the Original Principal Amount, if any, of such Security that
     remain subject to the original Purchase Notice and have been or will be
     delivered for purchase by the Company.

     The Paying Agent will promptly return to the respective Holders thereof any
Securities with respect to which a Purchase Notice has been withdrawn in
compliance with this Indenture, in which case, upon such return, the Purchase
Notice with respect thereto shall be deemed to have been withdrawn.

     Section 12.04. Deposit of Purchase Price. Prior to 10:00 a.m. (New York
City time) on the Purchase Date, the Company shall deposit with the Trustee or
with the Paying Agent an amount of cash (in immediately available funds if
deposited on such Purchase Date) sufficient to pay the aggregate Purchase Price
of all of the Securities or portions thereof which are to be purchased as of the
Purchase Date. The manner in which the deposit required by this Section 12.04 is
made by the Company shall be at the option of the Company, provided, however,
that such deposit shall be made in a manner such that the Trustee or a Paying
Agent shall have immediately available funds on the date of deposit.

     If a Paying Agent holds, in accordance with the terms hereof, cash
sufficient to pay the Purchase Price of any Security for which a Purchase Notice
has been tendered and not withdrawn in accordance with this Indenture on the
Business Day following the Purchase Date then, immediately after such Purchase
Date, such Security will cease to be outstanding, interest (including Accreted
Interest, Contingent Interest and Additional Interest, if any) will cease to
accrue and the rights of the Holder in respect thereof shall terminate (other
than the right to receive the Purchase Price as aforesaid).

     Section 12.05. Securities Purchased in Part. Any Security which is to be
purchased only in part shall be surrendered at the office of the Paying Agent
(with, if the Company, the Paying Agent or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company, the Paying Agent or the Trustee duly executed by, the Holder thereof or
such Holder's attorney duly authorized in writing) and the Company shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge except for any taxes to be paid by the Holder in the
event a Security is registered under a new name, a new Security or Securities,
of any authorized denomination as requested by such Holder in aggregate Original
Principal Amount equal to, and in exchange for, the portion of the Original
Principal Amount of the Security so surrendered that is not purchased.

     Section 12.06. Repayment to the Company. The Trustee and the Paying Agent
shall return to the Company any cash that remains unclaimed for two

                                       70

<PAGE>

years, subject to applicable unclaimed property law, together with interest, if
any, thereon held by them for the payment of the Purchase Price, provided,
however, that to the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 12.04 exceeds the aggregate Purchase Price of the
Securities or portions thereof which the Company is obligated to purchase as of
the Purchase Date, then promptly after the Business Day following the Purchase
Date, the Trustee or the Paying Agent, as applicable, shall return any such
excess to the Company. Thereafter, any Holder entitled to payment must look to
the Company for payment as a general creditor, unless an applicable abandoned
property law designates another Person.

     (a) If at any time prior to Stated Maturity that Securities remain
outstanding there shall occur a Fundamental Change, Securities shall be
purchased by the Company in integral multiples of $1,000 Original Principal
Amount at the option of the Holders thereof as of the date specified by the
Company that is not less than 20 Business Days nor more than 35 Business Days
after the date of the Company's notice, pursuant to clause (b) below, of the

the Accreted Principal Amount of the Securities to be purchased plus accrued and
unpaid interest (including Contingent Interest and Additional Interest, if any)
to, but excluding, the Fundamental Change Purchase Date, unless such Fundamental
Change Purchase Date falls after a Regular Record Date and on or prior to the
corresponding Interest Payment Date, in which case the Company shall pay the
full amount of accrued and unpaid interest (including Contingent Interest and
Additional Interest, if any) payable on such Interest Payment Date to the holder
of record at the close of business on such Regular Record Date.

     A "Fundamental Change" shall be deemed to have occurred at such time after
the original issuance of the Securities as any of the following occurs:

          (i) the Common Stock or other common stock into which the Securities
     are convertible is neither listed for trading on a United States national
     securities exchange nor approved for trading on the Nasdaq National Market
     or another established automated over the counter trading market in the
     United States;

                                       71

<PAGE>

          (ii) a "person" or "group" within the meaning of Section 13(d) of the
     Exchange Act, other than the Company, any Subsidiary of the Company or any
     employee benefit plan of the Company or any such Subsidiary, files a
     Schedule TO (or any other schedule, form or report under the Exchange Act)
     disclosing that such person or group has become the direct or indirect
     ultimate beneficial owner (as defined in Rule 13d-3 of the Exchange Act) of
     Voting Stock of the Company representing more than 50% of the voting power
     of the Company's Voting Stock;

          (iii) consummation of any share exchange, consolidation or merger of
     the Company pursuant to which the Common Stock will be converted into cash,

     transaction or a series of transactions) of all or substantially all of the
     consolidated assets of the Company and its Subsidiaries, taken as a whole,
     to any Person (other than the Company or one or more of the Company's
     Subsidiaries); provided, however, that a transaction where the holders of
     the Company's Voting Stock immediately prior to such transaction own,
     directly or indirectly, more than 50% of the aggregate voting power of all
     classes of Voting Stock of the continuing or surviving corporation or
     transferee or lessee immediately after such event shall not be a
     Fundamental Change; or

          (iv) Continuing Directors cease to constitute at least a majority of
     the Board of Directors;

provided, however, that a Fundamental Change shall not be deemed to have
occurred in respect of any of the foregoing if either (x) the Last Reported Sale
Price per share of Common Stock for any five Trading Days within the period of
10 consecutive Trading Days ending immediately before the later of the
Fundamental Change or the public announcement thereof shall equal or exceed 105%
of the Conversion Price of the Notes in effect immediately before the
Fundamental Change or the public announcement thereof; or (y) at least 90% of
the consideration (excluding cash payments for fractional shares) in the
transaction or transactions constituting the Fundamental Change consists of
shares of capital stock traded on a national securities exchange or reported by
the NASDAQ National Market (or which shall be so traded or reported when issued
or exchanged in connection with such Fundamental Change) (such securities being
referred to as "Publicly Traded Securities") and as a result of such transaction
or transactions the Securities become convertible into such Publicly Traded
Securities (excluding cash payments for fractional shares). For purposes of the
foregoing proviso the term "capital stock" of any Person means any and all
shares, interests, participations or other equivalents however designated of
corporate stock or other equity participations, including partnership interests,
whether general or limited, of such Person and any rights (other than debt

                                       72

securities convertible or exchangeable into an equity interest), warrants or
options to acquire an equity interest in such Person.

A "Continuing Director" shall mean a director who either was a member of the
Board of Directors on August 13, 2003 or who becomes a member of the Board of
Directors subsequent to that date and whose appointment, election or nomination
for election by the Company's stockholders is duly approved by a majority of the
Continuing Directors on the Board of Directors at the time of such approval,

Company on behalf of the Board of Directors in which such individual is named as
nominee for director.

     (b) On or before the 30/th/ day after the occurrence of a Fundamental
Change, the Company shall mail a written notice of the Fundamental Change to the
Trustee and any Paying Agent and to each Holder.

     The notice shall include the form of a Fundamental Change Purchase Notice
to be completed by the Holder and shall state:

          (i)    the events causing such Fundamental Change and the date of such
     Fundamental Change;

          (ii)   the date by which the Fundamental Change Purchase Notice
     pursuant to Section 13.01(c) must be given;

          (iv)   the Fundamental Change Purchase Price that will be payable with
     respect to the Securities as of the Fundamental Change Purchase Date;

          (v)    briefly, the conversion rights of the Securities;

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

          (vii)  the Conversion Rate and any adjustments thereto;

          (viii) that Securities as to which a Fundamental Change Purchase
     Notice has been given may be converted into Common Stock pursuant to
     Article 11 only to the extent that the Fundamental Change Purchase Notice
     has been withdrawn in accordance with the terms of this Indenture;

          (ix)   the procedures that the Holder must follow to exercise rights
     under this Section 13.01;

                                       73

<PAGE>

          (x)  the procedures for withdrawing a Fundamental Change Purchase
     Notice, including a form of notice of withdrawal; and

          (xi) that the Holder must satisfy the requirements set forth in the
     Securities in order to convert the Securities.

     If any of the Securities is in the form of a Global Security, then the
Company shall modify such notice to the extent necessary to accord with the
procedures of the Depositary applicable to the purchase of Global Securities. In
connection with providing such notice, the Company shall issue a press release
containing the information included in the notice and publish such information
on its website on the World Wide Web.

     (c) A Holder may exercise its rights specified in subsection (a) of this
Section 13.01 upon delivery of a written notice (which shall be in substantially
the form included as an attachment to the Securities and which may be delivered
by letter, overnight courier, hand delivery, facsimile transmission or in any
other written form and, in the case of Global Securities, may be delivered
electronically or by other means in accordance with the Depositary's customary
procedures) of the exercise of such rights (a "Fundamental Change Purchase
Notice") to any Paying Agent at any time prior to the close of business on the
Business Day immediately preceding the Fundamental Change Purchase Date.

     The delivery of such Security to any Paying Agent (together with all
necessary endorsements) at the office of such Paying Agent shall be a condition
to the receipt by the Holder of the Fundamental Change Purchase Price.

     The Company shall purchase from the Holder thereof, pursuant to this
Section 13.01, a portion of a Security if the Original Principal Amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this

of such Security.

     Any purchase by the Company contemplated pursuant to the provisions of this
Section 13.01 shall be consummated by the delivery of the consideration to be
received by the Holder promptly following the later of the Fundamental Change
Purchase Date and the time of delivery of the Security to the Paying Agent in

     Notwithstanding anything herein to the contrary, any Holder delivering to a
Paying Agent the Fundamental Change Purchase Notice contemplated by this
subsection (c) shall have the right to withdraw such Fundamental Change Purchase
Notice in whole or as to a portion thereof that is an Original Principal Amount
of $1,000 or an integral multiple thereof at any time prior to the close of

                                       74

<PAGE>

business on the Business Day immediately preceding the Fundamental Change
Purchase Date by delivery of a written notice of withdrawal to the Paying Agent
in accordance with Section 13.02.

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

     Anything herein to the contrary notwithstanding, in the case of Global
Securities, any Fundamental Change Purchase Notice may be delivered or withdrawn
and such Securities may be surrendered or delivered for purchase in accordance
with the applicable procedures of the Depositary as in effect from time to time.

     Section 13.02. Effect of Fundamental Change Purchase Notice.

     Upon receipt by any Paying Agent of the Fundamental Change Purchase Notice
specified in Section 13.01(c), the Holder of the Security in respect of which
such Fundamental Change Purchase Notice was given shall (unless such Fundamental
Change Purchase Notice is withdrawn as specified below) thereafter be entitled
to receive the Fundamental Change Purchase Price with respect to such Security.
Such Fundamental Change Purchase Price shall be paid to such Holder promptly

such Security (provided the conditions in Section 13.01(c) have been satisfied)
and (b) the time of delivery of such Security to a Paying Agent by the Holder
thereof in the manner required by Section 13.01(c). Securities in respect of
which a Fundamental Change Purchase Notice has been given by the Holder thereof

such Fundamental Change Purchase Notice unless such Fundamental Change Purchase
Notice has first been validly withdrawn as specified in the following paragraph.

     A Fundamental Change Purchase Notice may be withdrawn by means of a written
notice of withdrawal delivered to the office of the Paying Agent at any time
prior to the close of business on the Business Day immediately preceding the
applicable Fundamental Change Purchase Date specifying:

          (i) if certificated Securities have been issued, the certificate
     numbers for Securities in respect of which such notice of withdrawal is
     being submitted, or if not, such information as required by the Depositary;

          (ii) the Original Principal Amount, in integral multiples of $1,000,
     of the Securities with respect to which such notice of withdrawal is being
     submitted; and

<PAGE>

          (iii) the Original Principal Amount, if any, of such Securities that
     remain subject to the original Fundamental Change Purchase Notice and have
     been or will be delivered for purchase by the Company.

     The Paying Agent will promptly return to the respective Holders thereof any
Securities with respect to which a Fundamental Change Purchase Notice has been
withdrawn in compliance with this Indenture, in which case, upon such return,
the Fundamental Change Purchase Notice with respect thereto shall be deemed to
have been withdrawn.

Company shall deposit with the Trustee or with a Paying Agent an amount of cash
(in immediately available funds if deposited on the Fundamental Change Purchase
Date) sufficient to pay the aggregate Fundamental Change Purchase Price of all
the Securities or portions thereof that are to be purchased as of such
Fundamental Change Purchase Date. The manner in which the deposit required by
this Section 13.03 is made by the Company shall be at the option of the Company,
provided, however, that such deposit shall be made in a manner such that the
Trustee or a Paying Agent shall have immediately available funds on the date of
such deposit.

     If a Paying Agent holds, in accordance with the terms hereof, money
sufficient to pay the Fundamental Change Purchase Price of any Security for
which a Fundamental Change Purchase Notice has been tendered and not withdrawn
in accordance with this Indenture on the Fundamental Change Purchase Date then,
immediately following the Fundamental Change Purchase Date, such Security will
cease to be outstanding, interest (including Accreted Interest, Contingent
Interest and Additional Interest, if any) will cease to accrue and the rights of
the Holder in respect thereof shall terminate (other than the right to receive
the Fundamental Change Purchase Price). The Company shall publicly announce the
Original Principal Amount of Securities purchased as a result of such
Fundamental Change on or as soon as practicable after the Fundamental Change
Purchase Date.

     Section 13.04. Securities Purchased in Part. Any Security that is to be
purchased only in part shall be surrendered at the office of a Paying Agent and
promptly after the Fundamental Change Purchase Date the Company shall execute
and the Trustee, or any Authenticating Agent, shall authenticate and deliver to
the Holder of such Security, without service charge (other than amounts to be
paid in respect of applicable transfer taxes), a new Security or Securities, of
such authorized denomination or denominations in integral multiples of $1,000
Original Principal Amount as may be requested by such Holder, in aggregate
Original Principal Amount equal to, and in exchange for,

                                       76

<PAGE>

the portion of the Original Principal Amount of the Security so surrendered that
is not purchased.

     Section 13.05. Repayment to the Company. The Trustee and the Paying Agent
shall return to the Company any cash that remains unclaimed for two years,
subject to applicable unclaimed property law, together with interest, if any,
thereon held by them for the payment of the Fundamental Change Purchase Price;
provided, however, that to the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 13.03 exceeds the aggregate
Fundamental Change Purchase Price of the Securities or portions thereof which
the Company is obligated to purchase as of the Fundamental Change Purchase Date,
then on the Business Day following the Fundamental Change Purchase Date, the
Trustee or Paying Agent, as applicable, shall return any such excess to the
Company. Thereafter, any Holder entitled to payment must look to the Company for
payment as general creditors, unless an applicable abandoned property law
designates another Person.

either directly or through the Company, whether by virtue of any constitution,

contained by or in behalf of the Company shall bind its successors and assigns,
whether so expressed or not.

     Section 17.02. Acts of Board, Committee or Officer of Successor Company
Valid. Any act or proceeding by any provision of this Indenture authorized or
required to be done or performed by any board, committee or officer of the
Company shall and may be done and performed with like force and effect by the
like board, committee or officer of any corporation that shall at that time be
the successor of the Company.

     Section 17.03. Required Notices or Demands. Any notice or demand which by

prepaid in the United States addressed to such Holder at the address of such
Holder as shown on the Security Register. In any case, where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before

reliance upon such waiver.

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impractical to mail notice of any event to Holders when
such notice is required to be given pursuant to any provision of this Indenture,
then any manner of giving such notice as shall be satisfactory to the Trustee
shall be deemed to be a sufficient giving of such notice.

any request or application by the Company to the Trustee to take any action
under this Indenture, the Company shall furnish to the Trustee:

                       [FORM OF REVERSE SIDE OF SECURITY]

              Floating Rate Convertible Senior Debentures due 2033

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities") limited in aggregate Original Principal
Amount to $1,000,000,000, issued under an Indenture, dated as of August 13, 2003
(the "Indenture"), between the Company and The Bank of New York, as Trustee (the
"Trustee," which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. Capitalized terms used and not otherwise defined in
this Security are used as defined in the Indenture.

Interest.

     This Security will bear interest from August 13, 2003 or from the most
recent date to which interest has been paid or duly provided for, quarterly in
arrears on February 15, May 15, August 15 and November 15 of each year (each, an
"Interest Payment Date"), subject to Section 1.08 of the Indenture, commencing
November 15, 2003, at the rate per annum equal to 3-month LIBOR, reset quarterly
on each Interest Reset Date, minus 0.25%, to but excluding August 15, 2008.
Regardless of the level of 3-month LIBOR, however, the annual rate of interest
on the Securities during any Interest Period will never be less than zero.
Interest on this Security shall be calculated on the basis of a 360-day year and
the actual number of days elapsed during the related Interest Period. Interest
payable on this Security on any Interest Payment Date will include interest for
the immediately preceding Interest Period. The interest so payable and
punctually paid or duly provided for on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest payment, which shall be the
February 1, May 1, August 1 or November 1, as the case may be, immediately
preceding the relevant Interest Payment Date. Any interest which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the registered Holder hereof on the relevant
Regular Record Date by virtue of having been such Holder, and may be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Company, notice whereof shall be
given to the Holders of Securities not less than 10 days prior to such Special
Record Date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the

                                      A-6

<PAGE>

Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture.

     From and after August 15, 2008, the Company will no longer be required to
pay cash interest. The Original Principal Amount of this Security shall accrete
daily at the Applicable Yield for each Interest Period, which shall be 0% prior
to August 15, 2008.

Contingent Interest.

     From and after August 15, 2008, the Company will pay Contingent Interest on
this Security under the circumstances and in the amounts described in Article 14
of the Indenture. Such Contingent Interest, if any, shall be payable quarterly
in arrears on each Interest Payment Date to the Holder of this Security as of
the close of business on the Regular Record Date relating to such Interest
Payment Date.

Interest on Overdue Amounts.

     If the Accreted Principal Amount hereof or any portion of such Accreted
Principal Amount is not paid when due (whether upon acceleration pursuant to
Section 4.02 of the Indenture, upon the dates set for payment of the Redemption
Price, Purchase Price or Fundamental Change Purchase Price, or upon the Stated
Maturity of this Security) or if interest due hereon (including Contingent
Interest and Additional Interest, if any) (or any portion of such interest), is
not paid when due, then in each such case the overdue amount shall, to the
extent permitted by law, bear interest at the rate then borne by this Security
or, if any overdue amount exists on or after August 15, 2008, at the Applicable
Yield of this Security for the applicable Interest Period, compounded at the end
of such Interest Period, which interest shall accrue from the date such overdue
amount was originally due to the date payment of such amount, including interest
thereon, has been made or duly provided for. All such interest shall be payable
as set forth in the Indenture.

Method of Payment.

     Subject to the terms and conditions of the Indenture, the Company will make
payments in respect of Redemption Price, Purchase Price, Fundamental Change
Purchase Price and at Stated Maturity to Holders who surrender Securities to a
Paying Agent to collect such payments in respect of the Securities; provided
that if any Redemption Date, Purchase Date or Fundamental Change Date is an
Interest Payment Date, accrued and unpaid interest (including Contingent
Interest and Additional Interest, if any) shall be paid to the Holder of record
as of the applicable Regular Record Date. The Company will pay cash amounts in
money of the United States that at the time of payment is legal tender

                                      A-7

<PAGE>

for payment of public and private debts. However, the Company may make such cash
payments by check payable in such money; provided that payment by wire transfer
of immediately available funds will be required with respect to principal of and
interest (including Contingent Interest, if any) on all Global Securities and
all Securities of Holders of more than $25,000,000 aggregate Original Principal
Amount of Securities that have requested such method of payment and provided
wire transfer instructions to the Company or the Paying Agent at least five
Business Days prior to the applicable Interest Payment Date. If any Interest
Payment Date (other than an Interest Payment Date coinciding with the Stated
Maturity or earlier Redemption Date, Purchase Date, or Fundamental Change
Purchase Date) falls on a day that is not a Business Day, such Interest Payment
Date will be postponed to the next succeeding Business Day and no interest on
such payment will accrue for the period from and after the Interest Payment Date
to such next succeeding Business Day, provided that, if such Business Day falls
in the next succeeding calendar month, the Interest Payment Date will be the
Business Day immediately preceding such Interest Payment Date. If the Stated
Maturity, Redemption Date, Purchase Date or Fundamental Change Purchase Date of
this Security would fall on a day that is not a Business Day, the required
payment of interest, if any, and principal will be made on the next succeeding
Business Day and no interest on such payment will accrue and no principal will
accrete for the period from and after the Stated Maturity, Redemption Date,
Purchase Date or Fundamental Change Purchase Date to such next succeeding
Business Day.

Paying Agent, Conversion Agent and Registrar.

     Initially, the Trustee will act as Paying Agent, Conversion Agent and
Registrar. The Company may appoint and change any Paying Agent, Conversion
Agent, Registrar or co-registrar without notice, other than notice to the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may
act as Paying Agent, Conversion Agent, Registrar or co-registrar.

Indenture.

     The terms of the Securities include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
in effect from time to time (the "TIA"). The Securities are subject to all such
terms, and Holders are referred to the Indenture and the TIA for a statement of
those terms.

     The Securities are general unsecured obligations. The Indenture does not
limit other indebtedness of the Company.

                                      A-8

<PAGE>

Redemption at the Option of the Company.

     No sinking fund is provided for the Securities. Prior to August 15, 2008,
the Securities shall not be redeemable at the option of the Company. Beginning
on August 15, 2008 and until the Stated Maturity, the Securities are redeemable
for cash as a whole, or from time to time in part, at the option of the Company
at a Redemption Price equal to 100% of the Accreted Principal Amount of the
Securities, plus accrued and unpaid interest (including Contingent Interest and
Additional Interest, if any) to, but excluding, the Redemption Date, as provided
in Article 10 of the Indenture.

     If the Company redeems less than all of the outstanding Securities, the
Trustee will select the Securities to be redeemed (i) by lot; (ii) pro rata; or
(iii) by another method the Trustee considers fair and appropriate. If the
Trustee selects a portion of a Holder's Securities for partial redemption and
the Holder converts a portion of the same Securities, the converted portion
shall be deemed to be from the portion selected for redemption.

Notice of Redemption.

     Notice of redemption will be mailed at least 20 days but not more than 60
days before the Redemption Date to each Holder of Securities to be redeemed at
the Holder's registered address. If money sufficient to pay the Redemption Price
of all Securities (or portions thereof) to be redeemed on the Redemption Date is
deposited with the Paying Agent prior to or on the Redemption Date, immediately
after such Redemption Date interest shall cease to accrue and principal will
cease to accrete on such Securities or portions thereof. Securities in
denominations larger than $1,000 Original Principal Amount may be redeemed in
part but only in integral multiples of $1,000.

Purchase By the Company at the Option of the Holder.

     Each Holder has the right to require the Company to purchase the Securities
held by such Holder on August 15, 2008, 2013, 2018, 2023 and 2028, or if any
such day is not a Business Day, the next succeeding Business Day (each, a
"Purchase Date"). If required by any Holder, the Company shall purchase
Securities for cash at a Purchase Price equal to 100% of the Accreted Principal
Amount thereof, plus accrued and unpaid interest (including Contingent Interest
and Additional Interest, if any) to, but excluding, the Purchase Date, upon
delivery of a Purchase Notice containing the information set forth in the
Indenture, at any time from the opening of business on the date that is 20
Business Days prior to such Purchase Date until the close of business on the
Business Day immediately preceding such Purchase Date and upon delivery of the
Securities to the Paying Agent by the Holder as set forth in the Indenture.

                                      A-9

<PAGE>

         At the option of the Holder and subject to the terms and conditions of
the Indenture, the Company shall purchase all or a portion of the Securities
held by such Holder as of the date that is not less than 20 nor more than 35
Business Days after the date of the Company's notice to Holders of the
occurrence of a Fundamental Change occurring prior to Stated Maturity for a
Fundamental Change Purchase Price equal to 100% of the Accreted Principal Amount
thereof, plus accrued and unpaid interest (including Contingent Interest and
Additional Interest, if any) to, but excluding, the Fundamental Change Purchase
Date, unless such Fundamental Change Purchase Date falls after a Regular Record
Date and on or prior to the corresponding Interest Payment Date, in which case
the Company shall pay the full amount of accrued and unpaid interest (including
Contingent Interest and Additional Interest, if any) payable on such Interest
Payment Date to the Holder at the close of business on such Regular Record Date.

         Holders have the right to withdraw any Purchase Notice or Fundamental
Change Purchase Notice, as the case may be, by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the Indenture.

         As provided in the Indenture, if cash sufficient to pay the Purchase
Price or Fundamental Change Purchase Price, as the case may be, of all
Securities or portions thereof to be purchased as of the Purchase Date or the
Fundamental Change Purchase Date, as the case may be, is deposited with the
Paying Agent on the Purchase Date or the Fundamental Change Purchase Date, as
the case may be, all interest (including Contingent Interest and Additional
Interest, if any) ceases to accrue and principal ceases to accrete on such
Securities (or portions thereof) immediately after such Purchase Date or
Fundamental Change Purchase Date, as the case may be, and the Holder thereof
shall have no other rights as such (other than the right to receive the Purchase
Price or Fundamental Change Purchase Price, as the case may be, upon surrender
of such Security).

Conversion.

         Subject to the terms of the Indenture, the Holder of a Security may
convert the Security into shares of Common Stock at the Conversion Rate under
the circumstances set forth in Section 11.01 of the Indenture; provided,
however, the Company may satisfy its obligation with respect to any demand for
conversion by delivering Common Stock, cash or a combination of cash and Common
Stock. The Conversion Rate for the Securities on any Conversion Date shall be
determined as set forth in the Indenture. Upon conversion of a Security, the
Company shall deliver the Conversion Settlement Distribution within the time
periods set forth in Section 11.02 of the Indenture.

         A Security in respect of which a Holder has delivered a Purchase Notice
or a Fundamental Change Purchase Notice exercising the option of such Holder

                                      A-10

<PAGE>

to require the Company to purchase such Security may be converted only if such
notice of exercise is withdrawn in accordance with the terms of the Indenture.

         A Holder's right to convert the Securities into Common Stock of the
Company is also subject to the Company's right to elect pursuant to Section
11.03 of the Indenture to pay such Holder cash in lieu of delivering all or part
of such Common Stock; provided, however, that if such payment of cash is not
permitted pursuant to the provisions of the Indenture, the Company shall deliver
Common Stock (and cash in lieu of fractional shares of Common Stock) in
accordance with the Indenture, whether or not the Company has delivered a notice
pursuant to the Indenture to the effect that the Securities will be paid in
cash.

         If an Event of Default (other than a default in a cash payment upon
conversion of the Securities) shall have occurred and be continuing, the Company
shall deliver Common Stock in accordance with the terms of the Indenture,
whether or not the Company has delivered a notice pursuant to Section 11.03 of
the Indenture to the effect that the Securities would be paid in cash or a
combination of cash and Common Stock.

         A Holder may convert a portion of a Security if the Original Principal
Amount of such portion is $1,000 or an integral multiple of $1,000. No payment
or adjustment shall be made for dividends on the Common Stock except as provided
in the Indenture. On conversion of a Security, any accrued and unpaid interest
(including Contingent Interest, if any, Accreted Interest for all Interest
Periods concluding prior to the Conversion Date, if any, and Accreted Interest
for the Interest Period in which the Conversion Date occurs, if any) with
respect to such Security that is attributable to the period from the Issue Date
to the Conversion Date shall not be cancelled, extinguished or forfeited but
rather shall be deemed paid in full to the Holder of such Security through the
delivery of the Common Stock (together with the cash payment, if any, in lieu of
fractional shares), or cash or a combination of cash and Common Stock in lieu
thereof, in exchange for the Security being converted pursuant to the provisions
hereof, and the fair market value of the Common Stock (together with the cash
payment, if any, in lieu of fractional shares), or cash or a combination of cash
and Common Stock in lieu thereof, shall be treated as issued, to the extent
thereof, first in exchange for any accrued and unpaid interest (including
Contingent Interest, if any, Accreted Interest for all Interest Periods
concluding prior to the Conversion Date, if any, and Accreted Interest for the
Interest Period in which the Conversion Date occurs, if any) attributable to the
period from the Issue Date to the Conversion Date, and the balance, if any, of
such fair market value shall be treated as issued in exchange for the Original
Principal Amount of the Security being converted pursuant to the provisions
hereof. Notwithstanding the preceding sentence, on conversion of a Security
during the period from the close of business on any Regular Record Date
immediately preceding any Interest

                                      A-11

<PAGE>

Payment Date to the close of business on the Business Day immediately preceding
such Interest Payment Date, the Holder on such Regular Record Date shall receive
the interest payable on such Interest Payment Date.

         Securities or portions thereof surrendered for conversion during the
period from the close of business on any Regular Record Date immediately
preceding any Interest Payment Date to the close of business on the Business Day
immediately preceding such Interest Payment Date shall be accompanied by payment
to the Company or its order, in New York Clearing House funds or other funds
acceptable to the Company, of an amount equal to the interest payable on such
Interest Payment Date with respect to the Original Principal Amount of
Securities or portions thereof being surrendered for conversion; provided that
no such payment need be made if (1) the Company has specified a Redemption Date
that occurs during the period from the close of business on a Regular Record
Date to the close of business on the Interest Payment Date to which such Regular
Record Date relates, (2) the Company has specified a Fundamental Change Purchase
Date during such period or (3) only to the extent of overdue interest or overdue
Contingent Interest, any overdue interest or overdue Contingent Interest exists
on the Conversion Date with respect to the Securities converted.

         No fractional shares will be issued upon conversion; in lieu thereof,
an amount will be paid in cash pursuant to Section 11.04 of the Indenture. The
Company shall deliver cash or a check in lieu of any fractional share of Common
Stock

         The Company agrees, and by acceptance of a beneficial interest in a
Security each Holder and any beneficial owner of a Security shall be deemed to
agree to be bound (in the absence of an administrative determination or judicial
ruling to the contrary) by the Company's determination of the projected payment
schedule within the meaning of the contingent debt regulations, and accordingly
shall treat, for United States federal income tax purposes, the fair market
value of the Common Stock received upon the conversion of a Security (together
with any cash payment in lieu of fractional shares) or cash in lieu thereof, or
a combination of cash and Common Stock as a contingent payment on the Security
for purposes of Treasury Regulation Section 1.1275-4 or any successor provision.

         To convert a Security, a Holder must fulfill the conditions set forth
in Section 11.02 of the Indenture.

         The Conversion Rate will be adjusted as set forth in Article 11 of the

provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to

shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
